The aim of this prospective study was to evaluate radiographic levels of peri-implant bone crest as well as soft tissue response, papilla height, and buccal mucosa recession, in bone-level implants restored with platform switching after 1-year and 5-year follow-ups. This prospective study called for the placement of 59 implants to obtain a target of 90% power. To compensate for possible dropouts, the sample size was adjusted to 67 implants. To assess marginal bone level changes, periapical radiographs were taken at baseline, 1 year, and 5 years after the definitive restorations. Peri-implant soft tissue modifications were evaluated by performing a photographic sequence at 15 days, 1 year, and 5 years after implant restoration. Parameters measured were: (1) distance from the tip of the papilla to the contact point and (2) apicocoronal crown length. A one-way analysis of variance (ANOVA rank test) was used to compare quantitative data among the three time points studied. Mean marginal bone level changes were as follows: -0.06 ± 0.32 mm from baseline to 1 year, -0.23 ± 0.38 mm from 1 to 5 years, and -0.28 ± 0.45 mm from baseline to 5 years. In bone-level outcomes, no statistically significant differences were found between baseline and 1 year, while the mean differences between 1 and 5 years and baseline and 5 years showed statistically significant differences. In the soft tissue analysis, the distance from the tip of the papilla to the contact point showed the following values: baseline, 2.08 mm; 1 year, 1.54 mm; 5 years, 1.31 mm. No statistically significant differences were found between baseline and 1 year, whereas statistically significant differences between 1 and 5 years and baseline and 5 years were found. Apicocoronal crown length measurements showed the following values: baseline, 9.44 mm; 1 year, 9.28 mm; 5 years, 9.81 mm. No significant differences were found between times studied. This prospective clinical study of 67 bone-level implants restored according to the platform-switching concept reported that radiographic levels of peri-implant bone crest were statistically significant between 1 and 5 years and baseline and 5 years. For the soft tissue response, the greatest reduction in the distance from the papilla to the contact point from 1 to 5 years and baseline to 5 years was observed. No significant differences were shown in the buccal margin.

Objectives. We aimed to examine whether baseline hemoglobin levels in C282Y-homozygous patients are related to the degree of serum ferritin (SF) elevation and whether patients with different baseline hemoglobin have different phlebotomy requirements. Methods. A total of 196 patients (124 males and 72 females) who had undergone therapeutic phlebotomy and had SF and both pre- and posttreatment hemoglobin values were included in the study. Results. Bivariate correlation analysis suggested that baseline SF explains approximately 6 to 7% of the variation in baseline hemoglobin. The results also showed that males who had higher (≥150 g/L) baseline hemoglobin levels had a significantly greater reduction in their posttreatment hemoglobin despite requiring fewer phlebotomies to achieve iron depletion than those who had lower (<150 g/L) baseline hemoglobin, regardless of whether baseline SF was below or above 1000 µg/L. There were no significant differences between hemoglobin subgroups regarding baseline and treatment characteristics, except for transferrin saturation between male subgroups with SF above 1000 µg/L. Similar differences were observed when females with higher (≥138 g/L) baseline hemoglobin were compared with those with lower (<138 g/L) baseline hemoglobin. Conclusion. Dividing C282Y-homozygous patients into just two subgroups according to the degree of baseline SF elevation may obscure important subgroup variations. PMID:26380265

Objective To prospectively assess the relation between carotid plaque characteristics and the development of new cerebral white matter lesions (WMLs) at MRI. Methods Fifty TIA/stroke patients with ipsilateral 30–69% carotid stenosis underwent MRI of the plaque at baseline. Total plaque volume and markers of vulnerability to thromboembolism (lipid-rich necrotic core [LRNC] volume, fibrous cap [FC] status, and presence of intraplaque hemorrhage [IPH]) were assessed. All patients also underwent brain MRI at baseline and after one year. Ipsilateral cerebral WMLs were quantified with a semiautomatic method. Results Mean WML volume significantly increased over a one-year period (6.52 vs. 6.97 mm3, P = 0.005). WML volume at baseline and WML progression did not significantly differ (P>0.05) between patients with 30–49% and patients with 50–69% stenosis. There was a significant correlation between total plaque volume and baseline ipsilateral WML volume (Spearman ρ = 0.393, P = 0.005). There was no significant correlation between total plaque volume and ipsilateral WML progression. There were no significant associations between LRNC volume and WML volume at baseline and WML progression. WML volume at baseline and WML progression did not significantly differ between patients with a thick and intact FC and patients with a thin and/or ruptured FC. WML volume at baseline and WML progression also did not significantly differ between patients with and without IPH. Conclusion The results of this study indicate that carotid plaque burden is significantly associated with WML severity, but that there is no causal relationship between carotid plaque vulnerability and the occurrence of WMLs.

Objective. This study explored the feasibility of detecting hidden muscle activity in surface electromyogram (EMG) baseline. Approach. Power spectral density (PSD) analysis and multi-scale entropy (MSE) analysis were used. Both analyses were applied to computer simulations of surface EMG baseline with the presence (representing activity data) or absence (representing reference data) of hidden muscle activity, as well as surface electrode array EMG baseline recordings of healthy control and amyotrophic lateral sclerosis (ALS) subjects. Main results. Although the simulated reference data and the activity data yielded no distinguishable difference in the time domain, they demonstrated a significant difference in the frequency and signal complexity domains with the PSD and MSE analyses. For a comparison using pooled data, such a difference was also observed when the PSD and MSE analyses were applied to surface electrode array EMG baseline recordings of healthy control and ALS subjects, which demonstrated no distinguishable difference in the time domain. Compared with the PSD analysis, the MSE analysis appeared to be more sensitive for detecting the difference in surface EMG baselines between the two groups. Significance. The findings implied the presence of a hidden muscle activity in surface EMG baseline recordings from the ALS subjects. To promote the presented analysis as a useful diagnostic or investigatory tool, future studies are necessary to assess the pathophysiological nature or origins of the hidden muscle activity, as well as the baseline difference at the individual subject level.

To determine if baseline Sport Concussion Assessment Tool, third Edition (SCAT3) scores differ between athletes with and without disability. Cross-sectional comparison of preseason baseline SCAT3 scores for a range of England international footballers. Team doctors and physiotherapists supporting England football teams recorded players' SCAT 3 baseline tests from August 1, 2013 to July 31, 2014. A convenience sample of 249 England footballers, of whom 185 were players without disability (male: 119; female: 66) and 64 were players with disability (male learning disability: 17; male cerebral palsy: 28; male blind: 10; female deaf: 9). Between-group comparisons of median SCAT3 total and section scores were made using nonparametric Mann-Whitney-Wilcoxon ranked-sum test. All footballers with disability scored higher symptom severity scores compared with male players without disability. Male footballers with learning disability demonstrated no significant difference in the total number of symptoms, but recorded significantly lower scores on immediate memory and delayed recall compared with male players without disability. Male blind footballers' scored significantly higher for total concentration and delayed recall, and male footballers with cerebral palsy scored significantly higher on balance testing and immediate memory, when compared with male players without disability. Female footballers with deafness scored significantly higher for total concentration and balance testing than female footballers without disability. This study suggests that significant differences exist between SCAT3 baseline section scores for footballers with and without disability. Concussion consensus guidelines should recognize these differences and produce guidelines that are specific for the growing number of athletes living with disability.

Individuals differ widely in how steeply they discount future rewards. The sources of these stable individual differences in delay discounting (DD) are largely unknown. One candidate is the COMT Val158Met polymorphism, known to modulate prefrontal dopamine levels and affect DD. To identify possible neural mechanisms by which this polymorphism may contribute to stable individual DD differences, we measured 73 participants’ neural baseline activation using resting electroencephalogram (EEG). Such neural baseline activation measures are highly heritable and stable over time, thus an ideal endophenotype candidate to explain how genes may influence behavior via individual differences in neural function. After EEG-recording, participants made a series of incentive-compatible intertemporal choices to determine the steepness of their DD. We found that COMT significantly affected DD and that this effect was mediated by baseline activation level in the left dorsal prefrontal cortex (DPFC): (i) COMT had a significant effect on DD such that the number of Val alleles was positively correlated with steeper DD (higher numbers of Val alleles means greater COMT activity and thus lower dopamine levels). (ii) A whole-brain search identified a cluster in left DPFC where baseline activation was correlated with DD; lower activation was associated with steeper DD. (iii) COMT had a significant effect on the baseline activation level in this left DPFC cluster such that a higher number of Val alleles was associated with lower baseline activation. (iv) The effect of COMT on DD was explained by the mediating effect of neural baseline activation in the left DPFC cluster. Our study thus establishes baseline activation level in left DPFC as salient neural signature in the form of an endophenotype that mediates the link between COMT and DD. PMID:22586360

Objective: To investigate differences in different aspects of social participation and social capital among baseline daily smokers that had remained daily smokers, become intermittent smokers, or stopped smoking at one year follow up. Design/setting/participants/measurements: 12 507 individuals, aged 45–69 years, interviewed at baseline between 1992 and 1994 and at a one year follow up were investigated in this longitudinal study. The three groups of baseline daily smokers were compared to the reference population (baseline intermittent smokers and non-smokers) according to different aspects of social participation and social capital. A multivariate logistic regression model was used to assess differences in different aspects of social participation and social capital. Results: The baseline daily smokers that remained daily smokers at the one year follow up had significantly increased odds ratios of non-participation in study circles in other places than at work, meeting of organisations other than unions, theatre/cinema, arts exhibition, church, sports events, large gatherings of relatives, and private parties compared to the reference population. The baseline daily smokers that had become intermittent smokers at the one year follow up had significantly increased odds ratios of non-participation in church services. The baseline daily smokers that had stopped smoking had increased odds ratios of non-participation in having attended a meeting of organisations other than labour unions during the past year, having been to a theatre or cinema, and of having visited an arts exhibition during the past year. All three categories of baseline daily smokers had significantly decreased odds ratios of non-participation in night club/entertainment. Conclusions: The baseline daily smokers that had remained daily smokers at the one year follow up had particularly high rates of non-participation compared to the reference population in both activities specifically related to social capital, such as other study circles, meetings of organisations other than labour unions, and church attendance and cultural activities such as theatre/cinema and arts exhibition, although significantly lower participation in cultural activities and meetings of other organisations was also observed among daily smokers that had stopped smoking. All three baseline daily smoker groups had higher rates of having visited a night club during the past year. PMID:12958387

Objective. Event-related desynchronization (ERD) or synchronization (ERS) refers to the modulation of any EEG rhythm in response to a particular event. It is typically quantified as the ratio between a baseline and a task condition (the event). Here, we focused on the sensorimotor mu-rhythm. We explored the effects of different baselines on mu-power and ERD of the mu-rhythm during a motor imagery task. Methods. Eighteen healthy subjects performed motor imagery tasks while EEGs were recorded. Five different baseline movies were shown. For the imagery task a right-hand opening/closing movie was shown. Power and ERD of the mu-rhythm recorded over C3 and C4 for the different baselines were estimated. Main Results. 50% of the subjects showed relatively high mu-power for specific baselines only, and ERDs of these subjects were strongly dependent on the baseline used. In 17% of the subjects no preference was found. Contralateral ERD of the mu-rhythm was found in about 67% of the healthy volunteers, with a significant baseline preference in about 75% of that subgroup. Significance. The sensorimotor ERD quantifies activity of the brain during motor imagery tasks. Selection of the optimal baseline increases ERD.

The prevalence and possible long-term consequences of concussion remain an increasing concern to the U.S. military, particularly as it pertains to maintaining a medically ready force. Baseline testing is being used both in the civilian and military domains to assess concussion injury and recovery. Accurate interpretation of these baseline assessments requires one to consider other influencing factors not related to concussion. To date, there is limited understanding, especially within the military, of what factors influence normative test performance. Given the significant physical and mental demands placed on service academy members (SAM), and their relatively high risk for concussion, it is important to describe demographics and normative profile of SAMs. Furthermore, the absence of available baseline normative data on female and non-varsity SAMs makes interpretation of post-injury assessments challenging. Understanding how individuals perform at baseline, given their unique individual characteristics (e.g., concussion history, sex, competition level), will inform post-concussion assessment and management. Thus, the primary aim of this manuscript is to characterize the SAM population and determine normative values on a concussion baseline testing battery. All data were collected as part of the Concussion Assessment, Research and Education (CARE) Consortium. The baseline test battery included a post-concussion symptom checklist (Sport Concussion Assessment Tool (SCAT), psychological health screening inventory (Brief Symptom Inventory (BSI-18) and neurocognitive evaluation (ImPACT), Balance Error Scoring System (BESS), and Standardized Assessment of Concussion (SAC). Linear regression models were used to examine differences across sexes, competition levels, and varsity contact levels while controlling for academy, freshman status, race, and previous concussion. Zero inflated negative binomial models estimated symptom scores due to the high frequency of zero scores. Significant, but small, sex effects were observed on the ImPACT visual memory task. While, females performed worse than males (p < 0.0001, pη2 = 0.01), these differences were small and not larger than the effects of the covariates. A similar pattern was observed for competition level on the SAC. There was a small, but significant difference across competition level. SAMs participating in varsity athletics did significantly worse on the SAC compared to SAMs participating in club or intramural athletics (all p's < 0.001, η2 = 0.01). When examining symptom reporting, males were more than two times as likely to report zero symptoms on the SCAT or BSI-18. Intramural SAMs had the highest number of symptoms and severity compared to varsity SAMs (p < 0.0001, Cohen's d < 0.2). Contact level was not associated with SCAT or BSI-18 symptoms among varsity SAMs. Notably, the significant differences across competition level on SCAT and BSI-18 were sub-clinical and had small effect sizes. The current analyses provide the first baseline concussion battery normative data among SAMs. While statistically significant differences may be observed on baseline tests, the effect sizes for competition and contact levels are very small, indicating that differences are likely not clinically meaningful at baseline. Identifying baseline differences and significant covariates is important for future concussion-related analyses to inform concussion evaluations for all athlete levels.

The purpose of the present study was to investigate the possible effects of sociocultural influences, specifically pertaining to language and education, on baseline neuropsychological concussion testing as obtained via immediate postconcussion assessment and cognitive testing (ImPACT) of players from a professional baseball team. A retrospective chart review. Baseline testing of a professional baseball organization. Four hundred five professional baseball players. Age, languages spoken, hometown country location (United States/Canada vs overseas), and years of education. The 5 ImPACT composite scores (verbal memory, visual memory, visual motor speed, reaction time, impulse control) and ImPACT total symptom score from the initial baseline testing. The result of t tests revealed significant differences (P < 0.05) when comparing native English to native Spanish speakers in many scores. Even when corrected for education, the significant differences (P < 0.05) remained in some scores. Sociocultural differences may result in differences in computer-based neuropsychological testing scores.

Determine the extent that participation in Resource Mothers Program (RMP) home visiting improves maternal health at 3 months postpartum. A randomized controlled trial using RMPs in two urban and one rural location in a mid-Atlantic state. Community health workers from these RMPs enrolled teens into the study and the research team assigned participants to either the intervention group or telephone support control group using computerized randomization assignments. Data collection from baseline and 3 months postpartum using the Edinburgh Postnatal Depression Scale (EPDS) and the Prenatal Psychosocial Profile (PPP) is reported. The sample included 150 pregnant teens with a mean age of 17 years. Mean self-esteem scores between groups were not significantly different at baseline, but the RMP group self-esteem scores improved significantly at the 3 months postpartum interview (36.40 ± 5.63 for RMP vs. 34.10 ± 4.29 telephone control group, p = 0.049). Neither group was at risk for depression at baseline or 3 months postpartum. Because 60% of the total sample identified as Hispanic, post hoc analysis revealed significantly different baseline stress mean scores between Hispanic and non-Hispanic teens (p = 0.038); however, these differences were no longer significant by 3 months postpartum (p = 0.073). The EPDS scores by ethnicity were not different at baseline (p = 0.875) but were significantly different at 3 months (p = 0.007). The RMP home-visiting intervention can lead to improved self-esteem scores in teens, particularly in Hispanic teens. Improved self-esteem has been shown to lead to better parenting.

Baseline neurocognitive assessment plays a critical role in return-to-play decision making following sport-related concussions. Prior studies have assessed the effect of a variety of modifying factors on neurocognitive baseline test scores. However, relatively little investigation has been conducted regarding the effect of pretest exercise on baseline testing. The aim of our investigation was to determine the effect of pretest exercise on baseline Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) scores in adolescent and young adult athletes. We hypothesized that athletes undergoing self-reported strenuous exercise within 3 hours of baseline testing would perform more poorly on neurocognitive metrics and would report a greater number of symptoms than those who had not completed such exercise. Cross-sectional study; Level of evidence, 3. The ImPACT records of 18,245 adolescent and young adult athletes were retrospectively analyzed. After application of inclusion and exclusion criteria, participants were dichotomized into groups based on a positive (n = 664) or negative (n = 6609) self-reported history of strenuous exercise within 3 hours of the baseline test. Participants with a positive history of exercise were then randomly matched, based on age, sex, education level, concussion history, and hours of sleep prior to testing, on a 1:2 basis with individuals who had reported no pretest exercise. The baseline ImPACT composite scores of the 2 groups were then compared. Significant differences were observed for the ImPACT composite scores of verbal memory, visual memory, reaction time, and impulse control as well as for the total symptom score. No significant between-group difference was detected for the visual motor composite score. Furthermore, pretest exercise was associated with a significant increase in the overall frequency of invalid test results. Our results suggest a statistically significant difference in ImPACT composite scores between individuals who report strenuous exercise prior to baseline testing compared with those who do not. Since return-to-play decision making often involves documentation of return to neurocognitive baseline, the baseline test scores must be valid and accurate. As a result, we recommend standardization of baseline testing such that no strenuous exercise takes place 3 hours prior to test administration.

Traditional cardiovascular risk factors, such as hypertension and dyslipidemia, predispose individuals to cardiovascular disease, particularly patients with diabetes. We investigated the predictive value of baseline systolic blood pressure (SBP) and low-density lipoprotein cholesterol (LDL-C) on the risk of vascular outcomes in a large population of patients at high risk of future cardiovascular events. Data were pooled from the TNT (Treating to New Targets), CARDS (Collaborative Atorvastatin Diabetes Study), and IDEAL (Incremental Decrease in End-Points Through Aggressive Lipid Lowering) trials and included a total of 21,727 patients (TNT: 10,001; CARDS: 2838; IDEAL: 8888). The effect of baseline SBP and LDL-C on cardiovascular events, coronary events, and stroke was evaluated using a multivariate Cox proportional-hazards model. Overall, risk of cardiovascular events was significantly higher for patients with higher baseline SBP or LDL-C. Higher baseline SBP was significantly predictive of stroke but not coronary events. Conversely, higher baseline LDL-C was significantly predictive of coronary events but not stroke. Results from the subgroup with diabetes (5408 patients; TNT: 1501; CARDS: 2838; IDEAL: 1069) were broadly consistent with those of the total cohort: baseline SBP and LDL-C were significantly predictive of cardiovascular events overall, with the association to LDL-C predominantly related to an effect on coronary events. However, baseline SBP was not predictive of either coronary or stroke events in the pooled diabetic population. In this cohort of high-risk patients, baseline SBP and LDL-C were significantly predictive of cardiovascular outcomes, but this effect may differ between the cerebrovascular and coronary systems.

Bone turnover associated with orthodontic tooth movement is evidenced by increased bone turnover markers in gingival crevicular fluid (GCF). Postmenopausal women have an increased concentration of serum bone turnover markers. The filtrate of this serum makes up GCF, but little is known of the bone turnover around teeth in this cohort. The objective of this investigation was to compare the GCF bone turnover markers in premenopausal vs postmenopausal women receiving orthodontic treatment at baseline and at orthodontic activation. Twenty-eight women were enrolled in the study and separated into 2 groups: premenopausal (16) and postmenopausal (12). Bone turnover was evaluated by GCF at baseline and 24 hours after orthodontic appliance activation. GCF concentrations of RANKL and OPN were measured using ELISA. Baseline and change in concentrations were compared between groups. Baseline RANKL and OPN were significantly different between the premenopausal and postmenopausal groups (P <0.05). Both markers increased significantly from baseline to 24 hours after orthodontic appliance activation in both groups (P <0.05). However, the response to orthodontic activation was not significantly different between groups. Although postmenopausal women have a different bone turnover profile at baseline than do their premenopausal counterparts, there is no difference in their response to orthodontic activation. This confers a level of security associated with orthodontic activation. Future studies are warranted to construct biomarker curves throughout orthodontic therapy.

In birds, corticosterone (CORT) appears to facilitate reproductive activity because baseline and stress-induced CORT levels are elevated in breeding individuals compared with other times of the year. In particular, CORT is lower in the sex providing most of the parental care (i.e., incubation), which could be an important adaptation to tolerate stressors that result in abandoning reproduction. Therefore, one explanation for sex differences in CORT is that lower levels are favoured during the incubation/parental phase of reproduction. Using two species of uniparental shorebird - polyandrous red phalaropes (Phalaropus fulicarius) and polygynous white-rumped sandpipers (Calidris fuscicollis) - we predicted that the incubating sex would have lower baseline and stress-induced CORT, and incubating individuals with lower CORT would more effectively defend nests against a simulated intrusion, would return more quickly afterwards, and would ultimately have higher hatch success. We found that phalaropes followed the predicted pattern: incubating individuals (males) had lower baseline and stress-induced CORT than females but for baseline CORT these differences existed prior to males commencing incubation. Incubating male phalaropes with lower baseline and stress-induced CORT returned to incubate more quickly after a disturbance and there was non-significant tendency for baseline CORT to be lower in successful nests. In sandpipers, we observed no sex differences and no significant relationships between individual CORT levels and nest defence behaviours or hatch success. Our results demonstrate that in phalaropes at least, selection favours lower baseline and stress-induced CORT during the nesting period. These results can explain sex differences in stress-induced levels of CORT, however sex differences in baseline CORT were present prior to incubation. Copyright © 2013 Elsevier Inc.

High hydration is commonly used in renal studies to improve the completeness of urine collection. The renal effects of hydration are not well defined. Renal function was studied under fasting conditions (baseline) and after a meat meal (2 g of protein/kg body weight) in 12 healthy adults on a low and high hydration regimen of 0.5 and 4 mL of oral water per kg body weight/30 min, respectively. Urine flow, urinary and plasma Na, K, urea, and osmolality were stably different on low and high hydration regimens. At baseline, there were significant or borderline significant correlations of plasma and urine osmolality with glomerular filtration rate (GFR; inulin clearance) only in the low hydration regimen. GFR was higher in the low than the high hydration regimen at all time points. The difference was significant at baseline (19.2%) and at 90 to 180 minutes after the meal (14.4%). After the meal, GFR increased significantly over baseline values only in the high hydration regimen (30.0% at peak time). Urinary excretion of Na, urea, and osmoles was lower in the low than the high hydration regimen at all time points: The difference was significant for Na (at baseline) and osmoles (all time points). Urinary K excretion was not different in the two regimens. After the meal, there were significant increases in urinary excretion of Na (in the low hydration regimen) and urea (90 to 180 min after the meal). In fasting adults, high hydration lowered GFR and increased natriuresis. After a meat meal, GFR increased only in the high hydration regimen and natriuresis only in the low hydration regimen. Hydration affects GFR and natriuresis under fasting conditions and after a meat meal.
Validity and Reliability of Baseline Testing in a Standardized Environment.

The Immediate Postconcussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to determine cognitive recovery from concussion based on comparing post-injury scores to baseline scores. This model is based on the premise that ImPACT baseline test scores are a valid and reliable measure of optimal cognitive function at baseline. Growing evidence suggests that this premise may not be accurate and a large contributor to invalid and unreliable baseline test scores may be the protocol and environment in which baseline tests are administered. This study examined the effects of a standardized environment and administration protocol on the reliability and performance validity of athletes' baseline test scores on ImPACT by comparing scores obtained in two different group-testing settings. Three hundred-sixty one Division 1 cohort-matched collegiate athletes' baseline data were assessed using a variety of indicators of potential performance invalidity; internal reliability was also examined. Thirty-one to thirty-nine percent of the baseline cases had at least one indicator of low performance validity, but there were no significant differences in validity indicators based on environment in which the testing was conducted. Internal consistency reliability scores were in the acceptable to good range, with no significant differences between administration conditions. These results suggest that athletes may be reliably performing at levels lower than their best effort would produce. © The Author 2017. Published by Oxford University Press. All rights reserved.

We studied the effect of early antihypertensive treatment on death, major disability, and vascular events among patients with acute ischemic stroke according to their baseline SBP. We randomly assigned 4071 acute ischemic stroke patients with SBP between 140 and less than 220 mmHg to receive antihypertensive treatment or to discontinue all antihypertensive medications during hospitalization. A composite primary outcome of death and major disability and secondary outcomes were compared between treatment and control stratified by baseline SBP levels of less than 160, 160-179, and at least 180 mmHg. At 24 h after randomization, differences in SBP reductions were 8.8, 8.6 and 7.8 mmHg between the antihypertensive treatment and control groups among patients with baseline SBP less than 160, 160-179, and at least 180 mmHg, respectively (P < 0.001 among subgroups). At day 14 or hospital discharge, the primary and secondary outcomes were not significantly different between the treatment and control groups among subgroups. However, there was a significant interaction between antihypertensive treatment and baseline SBP subgroups on death (P = 0.02): odds ratio (95% CI) of 2.42 (0.74-7.89) in patients with baseline SBP less than 60 mmHg and 0.34 (0.11-1.09) in those with baseline SBP at least 180 mmHg. At the 3-month follow-up, the primary and secondary clinical outcomes were not significantly different between the treatment and control groups by baseline SBP levels. Early antihypertensive treatment had a neutral effect on clinical outcomes among acute ischemic stroke patients with various baseline SBP levels. Future clinical trials are warranted to test BP-lowering effects in acute ischemic stroke patients by baseline SBP levels. ClinicalTrials.gov Identifier: NCT01840072.
Activation of the mesocortical dopamine system by feeding: lack of a selective response to stress.

There is wide agreement that catecholamine systems in the prefrontal cortex are activated by stressful stimuli. To date, however, the extent to which other stimuli can increase the activity of these systems has received little attention. In the present study, the effects of tail pinch stress and feeding on dopamine and noradrenaline release in the prefrontal cortex of rats were examined using in vivo brain microdialysis. Both stimuli increased dopamine release, with peak effects reaching 212% above baseline for tail pinch and 165% above baseline for feeding. The effects of the two stimuli on peak dopamine release were not significantly different. Both stimuli also significantly increased noradrenaline release, with peak effects reaching 128% above baseline for tail pinch and 98% above baseline for feeding. The effects of the two stimuli on peak noradrenaline release were not significantly different. These results indicate that activation of catecholaminergic afferents to the prefrontal cortex is not specific to stress, but also occurs in response to non-stressors with positive motivational valence.

Results from hematology and clinical chemistry tests are presented for healthy captive-raised Trumpeter Swans (Cygnus buccinator) to help establish baseline data. Blood samples were obtained from 14 cygnets between the ages of three to four and seven to eight months that were the subjects of a study to teach migration routes to swans. Males and females differed significantly in asparatate aminotransferase, alanine aminotransferase and total protein. Age categories differed significantly in hematocrit, white blood cell counts, alkaline phosphatase, aspar-rate aminotransferase, glucose, cholesterol and uric acid. There were no significant differences among age categories in values of alanine aminotransferase, calcium, triglycerides and total protein.

Few dating violence prevention programs assess how variations in initial violence risk affects responsiveness. This study examines the efficacy of Date SMART, a dating violence and sexual risk prevention program designed to target high-risk adolescent girls, in preventing dating violence in the context of varying initial levels of depressive symptoms. A diverse sample of N = 109 female adolescents with a history of physical dating violence participated in a randomized controlled trial of the Date SMART program and a knowledge only (KO) comparison. Using baseline depression level as a primary risk factor, a series of multilevel models revealed significant main effects of baseline depression such that higher baseline depression was associated with greater physical dating violence perpetration and victimization. Results also showed a three-way interaction for assessment point, depressive symptoms, and condition for physical dating violence perpetration. Specifically, those with higher baseline depression in Date SMART showed significantly less physical dating violence perpetration at follow-ups compared with those with higher baseline depression in the KO group. This difference in violence reduction between conditions was not observed for those with lower baseline depression. Date SMART appears to effectively reduce physical dating violence perpetration in those with higher levels of initial risk. Current findings support that adolescents with different risk profiles respond differently to violence prevention programs.

To evaluate the efficiency of social-cognitive theory-guided oral hygiene interventions in adolescents and to identify predictors of adolescents' self-care practice. A cluster randomized trial included 197 15- to 16-year-olds from two secondary schools. The intervention group received three face-to-face educational hands-on sessions facilitated by a dentist and adolescents worked in pairs. Individual dental plaque levels were measured at baseline, after intervention, at six and at 12 months. The structured questionnaire inquired about gender, family socio-economic status (baseline), and different social-cognitive domain variables (baseline, six, and 12 months). At baseline, there were no statistically significant differences in dental plaque scores between the intervention and control groups (P = 0.183). At the 6-month follow-up, the intervention group had significantly less dental plaque than the control group (P = 0.047), but the intergroup difference in dental plaque levels was not significant at the 12-month follow-up (P = 0.400). Variations in dental plaque levels at different time periods were explained by the following predictors: family's socio-economic status, social-cognitive domain variables, group affiliation, and baseline plaque levels. Social-cognitive theory-guided interventions improved oral self-care of adolescents in the short term. After the intervention was discontinued, the improvement in oral self-care of adolescents lasted for another 5 months. © 2015 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Background: A diet high in vegetables, fruit, and fiber and low in fat decreased additional risk of secondary breast cancer events in women without hot flashes (HF−) compared with that in women with hot flashes (HF+), possibly through lowered concentrations of circulating estrogens. Objective: The objective was to investigate the intervention effect by baseline quartiles of dietary pattern among breast cancer survivors in the HF− subgroup of the Women's Healthy Eating and Living Study. Design: A randomized controlled trial compared a putative cancer prevention diet with a diet of 5 servings of vegetables and fruit daily in early-stage breast cancer survivors. Participants did not experience hot flashes at baseline (n = 896). We confirmed cancer status for 96% of participants ≈7.3 y after enrollment. Results: The study intervention achieved a large between-group difference in dietary pattern that, at 4 y, was not significantly different across baseline quartiles of dietary pattern. The intervention group experienced fewer breast cancer events than did the comparison group for all of the baseline quartiles. This difference was significant only in upper baseline quartiles of intake of vegetables, fruit, and fiber and in the lowest quartile of fat. A significant trend for fewer breast cancer events was observed across quartiles of vegetable-fruit and fiber consumption. Conclusions: The secondary analysis showing the decreased risk in the HF− subgroup was not explained by amount of change in dietary pattern achieved. The difference was strongest in the quartile with the most putatively cancer-preventive dietary pattern at baseline. PMID:19339393

To analyse sociodemographic, viroimmunological and clinical parameters in different HIV-transmission categories at baseline and during treatment, 3039 patients were followed up for 12 months after the initiation of a nelfinavir-based regimen. Multiple baseline parameters were significantly different in the diverse categories, including CD4 counts (P<0.0001) and viral load (P=0.02). There were differences in the groups regarding the CD4 response (P=0.01), but not the virological response (P=0.4), to therapy over time. Multivariate analyses revealed that transmission categories were significantly related to baseline CD4 counts (P=0.01), viral load at 12 months (P=0.0006), poorer adherence to therapy of injecting drug users (IDUs) vs. each of the other groups (P<0.001) and failure to complete the 12-month evaluation of IDU vs. heterosexual (P=0.003) and men who have sex with men (MSM) groups (P=0.02). We conclude that transmission categories had a significant influence on several baseline parameters and viroimmunological outcomes following highly active antiretroviral therapy (HAART), as well as on adherence to therapy and to medical appointments.

Background We aimed to introduce team-based learning (TBL) as one of the teaching methods for diagnostics and to compare its teaching effectiveness with that of the traditional teaching methods. Methods We conducted a randomized controlled trial on diagnostics teaching involving 111 third-year medical undergraduates, using TBL as the experimental intervention, compared with lecture-based learning as the control, for teaching the two topics of symptomatology. Individual Readiness Assurance Test (IRAT)-baseline and Group Readiness Assurance Test (GRAT) were performed in members of each TBL subgroup. The scores in Individual Terminal Test 1 (ITT1) immediately after class and Individual Terminal Test 2 (ITT2) 1 week later were compared between the two groups. The questionnaire and interview were also implemented to survey the attitude of students and teachers toward TBL. Results There was no significant difference between the two groups in ITT1 (19.85±4.20 vs 19.70±4.61), while the score of the TBL group was significantly higher than that of the control group in ITT2 (19.15±3.93 vs 17.46±4.65). In the TBL group, the scores of the two terminal tests after the teaching intervention were significantly higher than the baseline test score of individuals. IRAT-baseline, ITT1, and ITT2 scores of students at different academic levels in the TBL teaching exhibited significant differences, but the ITT1-IRAT-baseline and ITT2-IRAT-baseline indicated no significant differences among the three subgroups. Conclusion Our TBL in symptomatology approach was highly accepted by students in the improvement of interest and self-directed learning and resulted in an increase in knowledge acquirements, which significantly improved short-term test scores compared with lecture-based learning. TBL is regarded as an effective teaching method worthy of promoting. PMID:28331383

Younger age and female sex are both associated with greater mental stress in the general population, but limited data exist on the status of perceived stress in young and middle-aged patients presenting with acute myocardial infarction. We examined sex difference in stress, contributing factors to this difference, and whether this difference helps explain sex-based disparities in 1-month recovery using data from 3572 patients with acute myocardial infarction (2397 women and 1175 men) 18 to 55 years of age. The average score of the 14-item Perceived Stress Scale at baseline was 23.4 for men and 27.0 for women (P<0.001). Higher stress in women was explained largely by sex differences in comorbidities, physical and mental health status, intrafamily conflict, caregiving demands, and financial hardship. After adjustment for demographic and clinical characteristics, women had worse recovery than men at 1 month after acute myocardial infarction, with mean differences in improvement score between women and men ranging from -0.04 for EuroQol utility index to -3.96 for angina-related quality of life (P<0.05 for all). Further adjustment for baseline stress reduced these sex-based differences in recovery to -0.03 to -3.63, which, however, remained statistically significant (P<0.05 for all). High stress at baseline was associated with significantly worse recovery in angina-specific and overall quality of life, as well as mental health status. The effect of baseline stress on recovery did not vary between men and women. Among young and middle-aged patients, higher stress at baseline is associated with worse recovery in multiple health outcomes after acute myocardial infarction. Women perceive greater psychological stress than men at baseline, which partially explains women's worse recovery. © 2015 American Heart Association, Inc.

To compare the effects of 5% lidocaine patches and placebo patches on pain intensity and electromyographic (EMG) activity of an active myofascial trigger point (MTrP) of the upper trapezius muscle. Thirty-six patients with a MTrP in the upper trapezius muscle were randomly divided into two groups: 20 patients received lidocaine patches (lidocaine group) and 16 patients received placebo patches (placebo group). They used the patches for 12 h each day, for 2 weeks. The patch was applied to the skin over the upper trapezius MTrP. Spontaneous pain, pressure pain thresholds, pain provoked by a 4-kg pressure applied to the MTrP and trapezius EMG activity were measured before and after treatment. Baseline spontaneous pain values were similar in both groups and significantly lower in the lidocaine group than the placebo group after treatment. The baseline pressure pain threshold was significantly lower in the lidocaine group, but after treatment it was significantly higher in this group. Baseline and final values of the pain provoked by a 4-kg pressure showed no significant difference between the groups. Baseline EMG activity at rest and during swallowing of saliva was significantly higher in the lidocaine group, but no significant difference was observed after treatment. Baseline EMG activity during maximum voluntary clenching was similar in both groups, but significantly higher in the lidocaine group after treatment. These clinical and EMG results support the use of 5% lidocaine patches for treating patients with MTrP of the upper trapezius muscle.

The aim of this controlled, parallel design clinical study was to compare the effectiveness of an Er:YAG laser (ERL) to that of mechanical debridement using plastic curettes and antiseptic therapy for nonsurgical treatment of peri-implantitis. Twenty patients with moderate to advanced peri-implantitis lesions were randomly treated with either (1) an ERL using a cone-shaped glass fiber tip at an energy setting of 100 mJ/pulse and 10 pps (ERL), or (2) mechanical debridement using plastic curettes and antiseptic therapy with chlorhexidine digluconate (0.2%) (C). The following clinical parameters were measured at baseline, 3 and 6 months after treatment by one blinded and calibrated examiner: Plaque index (PI), bleeding on probing (BOP), probing depth (PD), gingival recession (GR) and clinical attachment level (CAL). At the baseline examination, there were no statistically significant differences in any of the investigated parameters. Mean value of BOP decreased in the ERL group from 83% at baseline to 31% after 6 months (P < 0.001) and in the C group from 80% at baseline to 58% after 6 months (P < 0.001). The difference between the two groups was statistically significant (P < 0.001, respectively). The sites treated with ERL demonstrated a mean CAL change from 5.8 +/- 1 mm at baseline to 5.1 +/- 1.1 mm (P < 0.01) after 6 months. The C sites demonstrated a mean CAL change from 6.2 +/- 1.5 mm at baseline to 5.6 +/- 1.6 mm (P < 0.001) after 6 months. After 6 months, the difference between the two groups was statistically not significant (P > 0.05). Within the limits of the present study, it was concluded that (i) at 6 months following treatment both therapies led to significant improvements of the investigated clinical parameters, and (ii) ERL resulted in a statistically significant higher reduction of BOP than C.

The aim of this study was to develop summary metrics and assess the construct validity for a virtual reality laparoscopic simulator (LapSim) by comparing the learning curves of three groups with different levels of laparoscopic expertise. Three groups of subjects ('expert', 'junior', and 'naïve') underwent repeated trials on three LapSim tasks. Formulas were developed to calculate scores for efficiency ('time-error') and economy of 'motion' ('motion') using metrics generated by the software after each drill. Data (mean +/- SD) were evaluated by analysis of variance (ANOVA). Significance was set at p < 0.05. All three groups improved significantly from baseline to final for both 'time-error' and 'motion' scores. There were significant differences between groups in time error performances at baseline and final, due to higher scores in the 'expert' group. A significant difference in 'motion' scores was seen only at baseline. We have developed summary metrics for the LapSim that differentiate among levels of laparoscopic experience. This study also provides evidence of construct validity for the LapSim.

In total knee arthroplasty (TKA), dynamic knee loading may loosen the artificial joint and bone or cause polyethylene wear after prolonged use. TKA decreases knee adduction moment at 6 months, but this effect is lost by 1 year post-operatively. However, lateral thrust after TKA has not been clarified. We hypothesized that like knee adduction moment, lateral thrust would return to baseline levels by 1 year post-operatively. Participants were 15 patients who underwent TKA for medial knee OA. Japanese Orthopaedic Association (JOA) score, numeric rating scale, and gait analysis (measurement of peak knee adduction moment, knee varus angle at peak knee adduction moment, lateral thrust, and gait speed) were performed preoperatively (baseline) and 3 weeks, 3 and 6 months, and 1 year post-operatively. JOA score improved from 55 ± 9.8 to 78 ± 12.1 at 1 year post-operatively, and pain decreased significantly from baseline at each follow-up (p < 0.001). Significant increases in gait speed were observed at 6 months and 1 year (p < 0.001). Peak knee adduction moment during stance phase was significantly lower at 3 weeks, 3 months, and 6 months compared to baseline (p < 0.05), but no significant changes were seen at 1 year. Knee varus at peak knee adduction moment did not differ significantly between any measurement points, while lateral thrust was decreased at 6 months and 1 year compared to baseline (p < 0.05). Temporal courses of changes up to 1 year after TKA differed between knee adduction moment and lateral thrust, so our hypothesis was rejected. IV.

To compare the performance of aberration detection algorithm for infectious disease outbreaks, based on two different types of baseline data. Cases and outbreaks of hand-foot-and-mouth disease (HFMD) reported by six provinces of China in 2009 were used as the source of data. Two types of baseline data on algorithms of C1, C2 and C3 were tested, by distinguishing the baseline data of weekdays and weekends. Time to detection (TTD) and false alarm rate (FAR) were adopted as two evaluation indices to compare the performance of 3 algorithms based on these two types of baseline data. A total of 405 460 cases of HFMD were reported by 6 provinces in 2009. On average, each county reported 1.78 cases per day during the weekdays and 1.29 cases per day during weekends, with significant difference (P < 0.01) between them. When using the baseline data without distinguish weekdays and weekends, the optimal thresholds for C1, C2 and C3 was 0.2, 0.4 and 0.6 respectively while the TTD of C1, C2 and C3 was all 1 day and the FARs were 5.33%, 4.88% and 4.50% respectively. On the contrast, when using the baseline data to distinguish the weekdays and weekends, the optimal thresholds for C1, C2 and C3 became 0.4, 0.6 and 1.0 while the TTD of C1, C2 and C3 also appeared equally as 1 day. However, the FARs became 4.81%, 4.75% and 4.16% respectively, which were lower than the baseline data from the first type. The number of HFMD cases reported in weekdays and weekends were significantly different, suggesting that when using the baseline data to distinguish weekdays and weekends, the FAR of C1, C2 and C3 algorithm could effectively reduce so as to improve the accuracy of outbreak detection.

This exploratory analysis assessed and compared patients' treatment satisfaction with empagliflozin plus metformin versus glimepiride plus metformin, using data obtained from the Diabetes Treatment Satisfaction Questionnaire, status version (DTSQs) collected in a randomized, double-blind, double-dummy clinical trial. Observed values for DTSQs scale score and each of its eight items were summarized by visit and treatment arm. Changes from baseline in these scores were analyzed using linear mixed models for repeated measures. The baseline scale score and item scores were comparable between empagliflozin plus metformin (n = 765) and glimepiride plus metformin (n = 780). Compared with baseline, patients reported significant treatment satisfaction increases and significant decreases in perceived hyperglycemia with both treatments at all visits. Also, compared with baseline, a significant increase in perceived frequency of hypoglycemia was observed in the glimepiride treatment group at all visits. No statistically significant treatment difference was observed in DTSQs scale score and its items at week 104. The difference between the treatment groups was significant and in favor of empagliflozin from week 28 onward for perceived frequency of hyperglycemia (P ≤ 0.006) and perceived frequency of hypoglycemia (P ≤ 0.011). Despite positive trends in favor of empagliflozin, there was no significant difference in DTSQs scale score between empagliflozin and glimepiride at 104 weeks. However, when compared with glimepiride, empagliflozin demonstrated significantly lower perceived frequency of hyperglycemia and hypoglycemia at all visits from week 28 onward. This finding is consistent with the clinical results reported for the EMPA-REG H2H-SU trial.

Psoriasis is a chronic inflammatory condition that occurs worldwide; however, few studies have examined this condition in non-Caucasian populations. The purpose of this study was to investigate racial/ethnic differences in demographics, psoriasis severity, efficacy, safety, and health-related quality of life in patients treated with etanercept using data from the Etanercept Assessment of Safety and Effectiveness (EASE) in Psoriasis trial. This is an investigator-initiated evaluation of data from the EASE study. The study included 2511 patients (Caucasian n=2164; Hispanic/Latino n=173; African American n=98; Asian n=76). Although baseline Physicians' Global Assessment (PGA) scores were similar, we found significant baseline differences in patient characteristics, prior therapy, percentage of body surface area (%BSA) affected and Dermatology Life Quality Index (DLQI) scores between the groups. At baseline, the Caucasian group had the longest disease duration (19 years), but the lowest percentage of BSA involvement (28%). The Asian group had the highest percentage of BSA involvement (41%). Baseline DLQI score was lowest for Caucasians (12.0) and highest for Hispanic/Latinos (14.6). At week 12, response to therapy was similar in all ethnic/racial groups. The BSA involvement was reduced by more than 50 percent for all groups, but remained significantly higher for the Asian group (17%) than for the Caucasian (13%; P=0.0105) and African American groups (13%; P=0.0461). At week 12, the mean Asian DLQI score of 5.2 was significantly higher (worse) than scores for the Caucasian (3.5; P=0.0001) and Hispanic/Latino groups (3.8; P=0.028). For both percentage of BSA and DLQI, differences among racial/ethnic groups in the percentage improvement from baseline were not statistically significant. Adverse event rates were similar for the groups. Patient characteristics at enrollment differed among ethnic groups, but no significant racial/ethnic differences were found in safety or efficacy of etanercept. However, racial/ethnic differences in the impact of psoriasis on quality of life were observed.

This study investigated the effects of lesion baseline characteristics and different strontium (Sr) to calcium (Ca) ratios in plaque fluid-like solutions (PF) on lesion de- and remineralization. Caries lesions were formed in enamel using three protocols: methylcellulose acid gel (MeC) and partially saturated lactic acid solutions containing carboxymethylcellulose (CMC) or not (SOLN). Lesions were exposed to PF with four distinct Sr:Ca molar ratios (0:1/3:1:3), but otherwise identical composition and total Sr+Ca molarity, for seven days. Lesions were characterized using transverse microradiography (TMR) at baseline and post-treatment. At baseline, MeC and CMC had similar integrated mineral loss values, whereas SOLN lesions were more demineralized. All lesions showed significant differences in their mineral distributions, with CMC and SOLN having lower R values (integrated mineral loss to lesion depth ratio) than MeC. Post-PF exposure, no interaction was found between lesion type and Sr:Ca ratio. Within lesion type, MeC demineralized, whereas CMC and SOLN exhibited some remineralization, with the differences between MeC and the other lesion types being of statistical significance. Within Sr:Ca ratio, the 1:3 ratio exhibited some remineralization whereas other groups tended to demineralize. Only the difference between groups SrCa1/3 and SrCa0 was of statistical significance. In summary, both lesion baseline characteristics and Sr:Ca ratio were shown to effect lesion de- and remineralization. Under the conditions of the study, high-R lesions are more prone to demineralize under PF-like conditions than low-R lesions. In addition, partial Sr substitution for Ca in PF was shown to enhance lesion remineralization. Copyright © 2012 Elsevier Ltd. All rights reserved.

Background: Periodontally accelerated osteogenic orthodontics is a clinical procedure that combines selective corticotomy, particulate grafting, and application of orthodontics. It reduces treatment time, increases stability of teeth, and prevents relapse of orthodontic tooth moment. The present study was aimed to explore the clinical and radiographic comparison of bone density changes, retraction time differences in buccal and palatal corticotomy with buccal corticotomy which was done by surgical bur. Materials and Methods: A split-mouth was designed in 16 patients and divided into right (buccal and palatal corticotomy) (Group I), left (buccal corticotomy) (Group II) sides. In both groups, decortication was done with surgical bur. Clinical parameters such as gingival bleeding index and probing pocket depth were recorded at baseline, 1 month, 3 months, and 6 months. Bone density changes were measured by computed tomography at baseline and after 6 months after surgery and also used for evaluating differences in bone density changes between two groups. Retraction time differences were also measured in both groups. Results: In both groups, there was significant difference between bone density changes at baseline and 6 months after surgery. However, the difference between two groups was not significant. The difference in clinical parameters between two groups was not significant. The difference in retraction time differences was not significant. Conclusion: Within limits of the study, it may be concluded that there was difference between bone density changes before and 6 months after surgery. Difference in total treatment time found to be no significant between two groups. PMID:28839422

Little is known regarding objective predictors of cachexia affecting patients with heart failure (HF). We studied 108 stable chronic systolic HF patients with serial echocardiography and biomarker measurements over 10 months. Cachexia was defined as weight loss ≥5 % from baseline or final BMI <20 kg/m 2 ; 18.5 % developed cachexia. While there were no significant differences in baseline or serial echocardiographic measures in those developing cachexia, we found significant differences in baseline amino-terminal pro-B type natriuretic peptide (NT-proBNP), highly sensitive troponin I, sST2, and endothelin-1. Baseline log NT-proBNP (hazard ratio (HR) = 2.57, p = 0.004) and edema (HR = 3.36, p = 0.04) were predictive of cachexia in an adjusted analysis. When serial measurement of biomarkers was considered, only percent time with NT-proBNP ≥1000 pg/mL was predictive of cachexia. Thus, a close association exists between baseline and serial measurement of NT-proBNP and HF cachexia.

Objective The evaluation sought to determine if a comprehensive, school-based asthma management program in a small, rural school district helped students improve asthma control. Methods To determine if students in the asthma program demonstrated better asthma control than students in a comparison school district, the evaluation team used a quasi-experimental, cross-sectional design and administered questionnaires assessing asthma control (which included FEV1 measurement) to 456 students with asthma in the intervention and comparison districts. Data were analyzed for differences in asthma control between students in the two districts. To determine if students in the intervention experienced increased asthma control between baseline and follow-up, the evaluation team used a one-group retrospective design. Program records for 323 students were analyzed for differences in percent of predicted forced expiratory volume in one second (FEV1) between baseline and follow-up. Results Students with asthma in the intervention district exhibited significantly better asthma control than students with asthma in the comparison district. Percent of predicted FEV1 did not change significantly between baseline and follow-up for the intervention participants; however, post hoc analyses revealed students with poorly-controlled asthma at baseline had significantly higher FEV1 scores at follow-up, and students with well-controlled asthma at baseline had significantly lower FEV1 scores at follow-up. Conclusions Findings suggest the comprehensive school-based program led to improvements in asthma control for students with poorly controlled asthma at baseline, and school-based programs need mechanisms for tracking students with initially well-controlled asthma in order to ensure they maintain control.

The esophageal intraluminal baseline impedance may be used to evaluate the status of mucosa integrity. Esophageal acid exposure decreases the baseline impedance. We aimed to compare baseline impedance in patients with various reflux events and with different acid-related parameters, and investigate the relationships between epithelial histopathologic abnormalities and baseline impedance. A total of 229 GERD patients and 34 controls underwent 24-h multichannel intraluminal impedance and pH monitoring (MII-pH monitoring), gastroendoscopy, and completed a GERD questionnaire (GerdQ). We quantified epithelial intercellular spaces (ICSs) and expression of tight junction (TJ) proteins by histologic techniques. Mean baseline values in reflux esophagitis (RE) (1752 ± 1018 Ω) and non-erosive reflux disease (NERD) (2640 ± 1143 Ω) were significantly lower than in controls (3360 ± 1258 Ω; p < 0.001 and p = 0.001, respectively). Among NERD subgroups, mean baselines in the acid reflux group (2510 ± 1239 Ω) and mixed acid/weakly acidic reflux group (2393 ± 1009 Ω) were much lower than in controls (3360 ± 1258 Ω; p = 0.020 and p < 0.001, respectively). The mean baseline in severe RE patients was significantly lower than in mild RE patients (LA-C/D vs. LA-A/B: 970 ± 505 Ω vs. 1921 ± 1024 Ω, p < 0.001). There was a significant negative correlation between baseline value and acid exposure time (AET) (r = -0.41, p < 0.001), and a weak but significant correlation (r = -0.20, p = 0.007) between baseline value and weakly AET. Negative correlations were observed between ICS and the baseline impedance (r = -0.637, p < 0.001) and claudin-1 and the baseline impedance (r = -0.648, p < 0.001). Patients with dominant acid reflux events and with longer AET have low baseline impedance. Baseline values are correlated with esophageal mucosal histopathologic changes such as dilated ICS and TJ alteration.

To examine the effect of postprandial thermogenesis on the cutaneous vasodilatory response, 10 healthy male subjects exercised for 30 min on a cycle ergometer at 50% of peak oxygen uptake, with and without food intake. Mean skin temperature, mean body temperature (Tb), heart rate, oxygen uptake, carbon dioxide elimination, and respiratory quotient were all significantly higher at baseline in the session with food intake than in the session without food intake. To evaluate the cutaneous vasodilatory response, relative laser Doppler flowmetry values were plotted against esophageal temperature (Tes) and Tb. Regression analysis revealed that the [Formula: see text] threshold for cutaneous vasodilation tended to be higher with food intake than without it, but there were no significant differences in the sensitivity. To clarify the effect of postprandial thermogenesis on the threshold for cutaneous vasodilation, the between-session difference in the Tes threshold and the Tb threshold were plotted against the between-session difference in baseline Tes and baseline Tb, respectively. Linear regression analysis of the resultant plot showed significant positive linear relationships (Tes: r = 0.85, P < 0.01; Tb: r = 0.67, P < 0.05). These results suggest that postprandial thermogenesis increases baseline body temperature, which raises the body temperature threshold for cutaneous vasodilation during exercise.

The management of sports-related concussions (SRCs) utilizes serial neurocognitive assessments and self-reported symptom inventories to assess recovery and safety for return to play (RTP). Because postconcussive RTP goals include symptom resolution and a return to neurocognitive baseline levels, clinical decisions rest in part on understanding modifiers of this baseline. Several studies have reported age and sex to influence baseline neurocognitive performance, but few have assessed the potential effect of sleep. We chose to investigate the effect of reported sleep duration on baseline Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) performance and the number of patient-reported symptoms. We hypothesized that athletes receiving less sleep before baseline testing would perform worse on neurocognitive metrics and report more symptoms. Cross-sectional study; Level of evidence, 3. We retrospectively reviewed 3686 nonconcussed athletes (2371 male, 1315 female; 3305 high school, 381 college) with baseline symptom and ImPACT neurocognitive scores. Patients were stratified into 3 groups based on self-reported sleep duration the night before testing: (1) short, <7 hours; (2) intermediate, 7-9 hours; and (3) long, ≥9 hours. A multivariate analysis of covariance (MANCOVA) with an α level of .05 was used to assess the influence of sleep duration on baseline ImPACT performance. A univariate ANCOVA was performed to investigate the influence of sleep on total self-reported symptoms. When controlling for age and sex as covariates, the MANCOVA revealed significant group differences on ImPACT reaction time, verbal memory, and visual memory scores but not visual-motor (processing) speed scores. An ANCOVA also revealed significant group differences in total reported symptoms. For baseline symptoms and ImPACT scores, subsequent pairwise comparisons revealed these associations to be most significant when comparing the short and intermediate sleep groups. Our results indicate that athletes sleeping fewer than 7 hours before baseline testing perform worse on 3 of 4 ImPACT scores and report more symptoms. Because SRC management and RTP decisions hinge on the comparison with a reliable baseline evaluation, clinicians should consider sleep duration before baseline neurocognitive testing as a potential factor in the assessment of athletes' recovery.

The influence of the piston-cassette pump fill stroke on the pharmacodynamic response to sodium nitroprusside was evaluated prospectively in 10 adult patients in the surgical intensive-care unit. Simultaneous analog recordings of blood pressure and fill stroke were made over three complete pump fill cycles in each patient. Sodium nitroprusside flow rates and concentrations were recorded throughout the data-collection period. Analysis was based on the maximum pressure obtained during the two-minute baseline period before a fill stroke (Pmax baseline), the pressure at the initiation of the fill stroke (P initial), and the maximum pressure obtained during the two-minute period after the fill stroke (Pmax postfill). The maximum systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean blood pressure (MBP) during the baseline and post-fill-stroke periods were significantly different. The mean (+/- S.D.) variability in pressure between the time periods Pmax baseline and Pmax postfill was 3.9 +/- 5.8 mm Hg for SBP (range, -8 to +16), 3.5 +/- 5.7 mm Hg for DBP (range, -7 to +13), and 3.6 +/- 5.6 mm Hg for MBP (range, -7 to +14). The likelihood of a pharmacodynamic change was inconsistent both between and within patients. Within patients the difference between cycles for the variability between time periods ranged from a minimum of 2 mm Hg to a maximum of 16 mm Hg for SBP, 2 mm Hg to 17 mm Hg for DBP, and 1 mm Hg to 17 mm Hg for MBP. The variability within the baseline period (Pmax baseline - P initial) in SBP was significantly greater than the variability between the time periods, while the differences for DBP and MBP were not significant.(ABSTRACT TRUNCATED AT 250 WORDS)

To evaluate the effect of antacid swish in the salivary pH values and to monitor the pH changes in subjects with and without dental erosion after multiple acid challenge tests. 20 subjects with tooth erosion were matched in age and gender with 20 healthy controls according to specific inclusion/exclusion criteria. Baseline measures were taken of salivary pH, buffering capacity and salivary flow rate using the Saliva Check System. Subjects swished with Diet Pepsi three times at 10-minute intervals. Changes in pH were monitored using a digital pH meter at 0-, 5-, and 10- minute intervals and at every 5 minutes after the third swish until pH resumed baseline value or 45 minutes relapse. Swishing regimen was repeated on a second visit, followed by swishing with sugar-free liquid antacid (Mylanta Supreme). Recovery times were also recorded. Data was analyzed using independent t-tests, repeated measures ANOVA, and Fisher's exact test (α= 0.05). Baseline buffering capacity and flow rate were not significantly different between groups (P= 0.542; P= 0.2831, respectively). Baseline salivary pH values were similar between groups (P= 0.721). No significant differences in salivary pH values were found between erosion and non-erosion groups in response to multiple acid challenges (P= 0.695) or antacid neutralization (P= 0.861). Analysis of salivary pH recovery time revealed no significant differences between groups after acid challenges (P= 0.091) or after the use of antacid (P= 0.118). There was a highly significant difference in the survival curves of the two groups on Day 2, with the non-erosion group resolving significantly faster than the erosion group (P= 0.0086).

Intravenous lipid emulsion (ILE) is an adjunctive antidote used in selected critically ill poisoned patients. These patients may also require administration of advanced cardiac life support (ACLS) drugs. Limited data is available to describe interactions of ILE with standard ACLS drugs, specifically epinephrine. Twenty rats with intra-arterial and intravenous access were sedated with isoflurane and split into ILE or normal saline (NS) pretreatment groups. All received epinephrine 15 μm/kg intravenously (IV). Continuous mean arterial pressure (MAP) and heart rate (HR) were monitored until both indices returned to baseline. Standardized t tests were used to compare peak MAP, time to peak MAP, maximum change in HR, time to maximum change in HR, and time to return to baseline MAP/HR. There was a significant difference (p = 0.023) in time to peak MAP in the ILE group (54 s, 95 % CI 44-64) versus the NS group (40 s, 95 % CI 32-48) and a significant difference (p = 0.004) in time to return to baseline MAP in ILE group (171 s, 95 % CI 148-194) versus NS group (130 s, 95 % CI 113-147). There were no significant differences in the peak change in MAP, peak change in HR, time to minimum HR, or time to return to baseline HR between groups. ILE-pretreated rats had a significant difference in MAP response to epinephrine; ILE delayed the peak effect and prolonged the duration of effect of epinephrine on MAP, but did not alter the peak increase in MAP or the HR response.

Sex differences in Parkinson disease clinical features have been reported, but few studies have examined sex influences on use of dopaminergic medication in early Parkinson disease. The objective of this study was to test if there are differences in the type of dopaminergic medication used and levodopa equivalent daily dose between men and women with early Parkinson disease enrolled in a large multicenter study of Creatine as a potential disease modifying therapy - the National Institute of Neurological Disorders and Stroke Exploratory Trials in Parkinson Disease Long-Term Study-1. Baseline data of 1,741 participants from 45 participating sites were analyzed. Participants from the United States and Canada were enrolled within five years of Parkinson Disease diagnosis. Two outcome variables were studied: type of dopaminergic medication used and levodopa equivalent daily dose at baseline in the Long-Term Study-1. Chi-square statistic and linear regression models were used for statistical analysis. There were no statistically significant differences in the frequency of use of different types of dopaminergic medications at baseline between men and women with Parkinson Disease. A small but statistically significant difference was observed in the median unadjusted levodopa equivalent daily dose at baseline between women (300 mg) and men (325 mg), but this was not observed after controlling for disease duration (years since Parkinson disease diagnosis), disease severity (Unified Parkinson's Disease Rating Scale Motor and Activities of Daily Living Scores), and body weight. In this large multicenter study, we did not observe sex differences in the type and dose of dopaminergic medications used in early Parkinson Disease. Further research is needed to evaluate the influence of male or female sex on use of dopaminergic medication in mid- and late-stage Parkinson Disease.

Nutrition education for student volunteers can enhance their skills, and they can act as change agents in the community. There is a dearth of data from India on the effectiveness of different communication tools in providing nutrition education to student volunteers. This study aims to examine the comparative effectiveness of two different methods of communication--lectures in the classroom aided by print material, and a televised version of a local folk-dance form--for providing nutrition education to student community volunteers in a South Indian state. Interventions were conducted during two mega-camps of student volunteers (camps 1 and 2) with 70 and 137 participants, respectively. Their knowledge levels were tested at baseline. Camp 1 received the lecture intervention and camp 2 the televised folk-dance intervention. Knowledge scores were measured before and after the intervention in each camp, and the two camps were compared for significant improvements in knowledge. At baseline, the knowledge levels of students in both camps were comparable. Significant improvement in knowledge was observed in both camps after intervention (p < .05). Although there was no significant difference between the camps in improvement in knowledge, a significant difference was observed when only the positive increments (improvement over baseline) were compared. The televised version of the folk-dance form was better in bringing about positive increment.

To evaluate the clinical outcomes of intentionally replanted maxillary single-rooted teeth with vertical root fractures (VRFs) after being repaired extraorally using 4-methacryloxyethyl trimellitate anhydride/methacrylate-tri-n-butyl borane (4-META/MMA-TBB) resin cement. Twenty-one root filled maxillary single-rooted teeth with VRFs were evaluated. After atraumatic extraction, fractured fragments were adhesively cemented. The teeth were then replanted and splinted to the neighbouring teeth for 2 weeks. Plaque index (PI), gingival index (GI), probing depth (PD) and clinical attachment level (CAL) were assessed at baseline, 6 and 12 months, and radiographic evaluations were made using PAI scores at baseline and 12 months. Mobility was evaluated using periotest values (PTV) at baseline, 1, 3, 6 and 12 months. Replanted teeth, contralateral teeth (control teeth) and adjacent teeth were analysed statistically using repeated measures one-way anova, unpaired t-tests and Wilcoxon matched-pairs signed-rank tests. Two teeth were extracted in the first month after surgery. PI, GI, CAL and PD scores of the replanted teeth were significantly lower at 6 month (P < 0.0001 for all) and 12 month (P < 0.0001 for all) postoperatively when compared to baseline, but the values were not significantly different from those of the control and adjacent teeth. PTV of the test teeth increased significantly (P < 0.0001) after the intervention and decreased to baseline levels by month 12. PTVs were significantly higher (P < 0.05) at baseline, 1, 3 and 6 months in the test teeth when compared with the control teeth, but were not significantly different at month 12. PAI scores of teeth with VRF were significantly lower (P < 0.05) at 12 months compared with baseline. Adhesive cementation and intentional replantation were an effective treatment modality for this group of vertically fractured maxillary single-rooted teeth. The clinical periodontal parameters decrease by month 6, and the mobility returned to the physiological limits of natural teeth 12 months after replantation. © 2015 International Endodontic Journal.

This study addressed the question whether the composition of supposedly 'healthy' or 'unhealthy' dietary regimes has a calorie-independent short-term effect on biomarkers of metabolic stress and vascular risk in healthy individuals. Healthy male volunteers (age 29.5 ± 5.9 years, n = 39) were given a standardized baseline diet for two weeks before randomization into three groups of different dietary regimes: fast food, Mediterranean and German cooking style. Importantly, the amount of calories consumed per day was identical in all three groups. Blood samples were analyzed for biomarkers of cardiovascular risk and metabolic stress after two weeks of the baseline diet and after two weeks of the assigned dietary regime. No dietary intervention affected the metabolic or cardiovascular risk profile when compared in-between groups or compared to baseline. Subjects applied to the Mediterranean diet showed a statistically significant increase of uric acid compared to baseline and compared to the German diet group. Plasma concentrations of urea were significantly higher in both the fast food group and the Mediterranean group, when compared to baseline and compared to the German diet group. No significant differences were detected for the levels of vitamins, trace elements or metabolic stress markers (8-hydroxy-2-deoxyguanosine, malondialdehyde and methylglyoxal, a potent glycating agent). Established parameters of vascular risk (e.g. LDL-cholesterol, lipoprotein(a), homocysteine) were not significantly changed in-between groups or compared to baseline during the intervention period. The calorie-controlled dietary intervention caused neither protective nor harmful short-term effects regarding established biomarkers of vascular or metabolic risk. When avoiding the noxious effects of overfeeding, healthy individuals can possess the metabolic capacity to compensate for a potentially disadvantageous composition of a certain diet.

Procalcitonin has been found to be a good marker for the diagnosis of sepsis. However, data on procalcitonin levels to predict the clinical outcome in patients with sepsis are limited. The aim of our study was to estimate serum procalcitonin levels in patients with sepsis and to identify its relationship with the clinical outcome. This was a prospective observational study conducted on 112 patients with sepsis admitted to the medical wards and medical intensive care unit of a tertiary care teaching hospital. Serum procalcitonin was measured at baseline before antibiotic administration and on day 5. The clinical outcome studied was death or survival on day 28. Baseline mean serum procalcitonin was highest in patients with septic shock and lowest in patients having sepsis without organ dysfunction. Mean values of procalcitonin at baseline and on day 5 were significantly higher in non-survivors when compared with survivors. There was a significant difference in the change in procalcitonin levels from baseline to day 5 between survivors and non-survivors, with survivors having declining values on day 5 while non-survivors had increasing values from baseline. The baseline APACHE II and SOFA scores also showed a significant correlation with the baseline procalcitonin level. Declining values of procalcitonin therefore indicate a favourable clinical outcome in patients with sepsis.

Two case reports suggest that metronidazole treatment for Clostridium difficile infections (CDI) increases tacrolimus (TAC) trough levels. The primary objective of this study was to determine the clinical significance of this potential interaction in transplant patients receiving CDI treatment. Currently, no robust literature exists to estimate a magnitude of pharmacokinetic interaction between metronidazole and TAC. In this retrospective study, the effects of CDI and metronidazole treatment on TAC levels in 52 adult solid organ transplant patients were investigated. The primary outcome was to determine the difference in dose-normalized TAC levels between baseline and symptom resolution in patients treated with metronidazole or vancomycin. The secondary outcome was to determine the difference in dose-normalized TAC levels at baseline and CDI diagnosis. The average change in log-transformed dose-normalized TAC levels from baseline to symptom resolution was 0.99 for metronidazole (n = 35) and 1.04 for vancomycin (n = 17) treatment. The mean difference between the groups was 0.96 (95% confidence interval: 0.74-1.24). No significant difference was found between dose-normalized TAC levels at CDI diagnosis and baseline (P = 0.37). CDI treatment with metronidazole was not associated with a >30% increase in TAC levels compared with vancomycin. Both treatment groups required TAC dose adjustments to maintain goal TAC levels and those treated with metronidazole did not require a significantly greater dose adjustment. © 2016 John Wiley & Sons A/S.

This study investigated the prevalence of driven exercise (DE) and its role in treatment outcome for adolescents with bulimia nervosa (BN) and anorexia nervosa (AN). Participants were 201 adolescents with an eating disorder (ED) (80 with BN and 121 with AN) presenting for outpatient treatment at two specialist clinics. All adolescents participated in one of two randomized controlled trials. Descriptive statistics were conducted to evaluate the presence and frequency of baseline DE. Exploratory hierarchical regressions were used to evaluate the effect of baseline DE on treatment outcomes. About 66.3% of adolescents with BN and 23.1% of adolescents with AN presented with baseline DE. The presence of baseline DE predicted significantly worse outcomes for adolescents with AN in terms of ED symptom severity (ps < .004); however, baseline DE did not significantly predict any of the evaluated outcomes for adolescents with BN (ps < .05). The results of this secondary exploratory data suggest that DE is prevalent for adolescents with BN and AN. However, DE may be related to different constructs for adolescents with AN than those with BN, suggesting differences in treatment needs. © 2014 Wiley Periodicals, Inc.

Impaired mobility, such as falls, may be an early biomarker of subsequent cognitive decline and is associated with subclinical alterations in both brain structure and function. In this 12-month prospective study, we examined whether there are volumetric differences in gray matter and subcortical regions, as well as cerebral white matter, between older fallers and non-fallers. In addition, we assessed whether these baseline volumetric differences are associated with changes in cognitive function over 12 months. A total of 66 community-dwelling older adults were recruited and categorized by their falls status. Magnetic resonance imaging occurred at baseline and participants’ physical and cognitive performances were assessed at baseline and 12-months. At baseline, fallers showed significantly lower volumes in gray matter, subcortical regions, and cerebral white matter compared with non-fallers. Notably, fallers had significantly lower left lateral orbitofrontal white matter volume. Moreover, lower left lateral orbitofrontal white matter volume at baseline was associated with greater decline in set-shifting performance over 12 months. Our data suggest that falls may indicate subclinical alterations in regional brain volume that are associated with subsequent decline in executive functions. PMID:27079333

To examine potential disease-modifying effects of statin drugs, we conducted a 12-month randomized, placebo-controlled clinical trial of simvastatin in cognitively normal adults using change in CSF Alzheimer disease biomarkers as primary outcome measure. Participants were 45-64 years old and statin-naive with normal cognition and normal or mildly elevated cholesterol. Forty-six participants completed the 1-year study per protocol (25 in the simvastatin and 21 in the placebo group). Simvastatin was titrated to 40 mg/d. CSF Aβ 42 , total tau, and p-tau 181 were measured at baseline and after 12 months of treatment using the INNO-BIA AlzBio3 assay. We used analysis of covariance to assess differences in biomarker change from baseline between treatment groups, adjusting for age, sex, and APOE ε4 status. Changes from baseline did not differ significantly between treatment groups for any CSF biomarker, with p values of 0.53, 0.36, and 0.25 for CSF Aβ 42 , total tau, and p-tau 181 , respectively. There was no significant modifying effect of sex, APOE ε4, or baseline high-density lipoprotein or triglycerides on treatment group for any of the biomarkers (all p > 0.18). However, a significant interaction between treatment group and baseline low-density lipoprotein (LDL) was observed for p-tau 181 ( p = 0.003), where greater decreases from baseline in CSF p-tau 181 concentrations were associated with higher baseline LDL level for the simvastatin group. Simvastatin-related reductions in CSF p-tau 181 concentrations may be modulated by LDL cholesterol. The potential disease-modifying effects of simvastatin on CSF phospho-tau should be further investigated in persons with hypercholesterolemia. © 2017 American Academy of Neurology.

Previous research has found that a common polymorphism in the serotonin transporter gene (5-HTTLPR) is an important mediator of individual differences in brain responses associated with emotional behaviour. In particular, relative to individuals homozygous for the l-allele, carriers of the s-allele display heightened amygdala activation to emotional compared to non-emotional stimuli. However, there is some debate as to whether this difference is driven by increased activation to emotional stimuli, resting baseline differences between the groups, or decreased activation to neutral stimuli. We performed functional imaging during an implicit facial expression processing task in which participants viewed angry, sad and neutral faces. In addition to neutral faces, we included two further baseline conditions, houses and fixation. We found increased amygdala activation in s-allele carriers relative to l-homozygotes in response to angry faces compared to neutral faces, houses and fixation. When comparing neutral faces to houses or fixation, we found no significant difference in amygdala response between the two groups. In addition, there was no significant difference between the groups in response to fixation when compared with a houses baseline. Overall, these results suggest that the increased amygdala response observed in s-allele carriers to emotional faces is primarily driven by an increased response to emotional faces rather than a decreased response to neutral faces or an increased resting baseline. The results are discussed in relation to the tonic and phasic hypotheses of 5-HTTLPR-mediated modulation of amygdala activity. Copyright © 2010 Elsevier Ltd. All rights reserved.

To explore whether poor initial insight during a first episode of mania with psychotic features was predictive of poor psychosocial and clinical outcomes at 18 months. Secondary analysis was performed on data collected during an 8-week RCT comparing the efficacy of olanzapine versus chlorpromazine as an adjunct to lithium, and at 18-month follow-up. 74 participants were divided into three groups (no insight, partial insight, and full insight) according to the insight item from the Young Mania Rating Scale (YMRS). Differences between these three groups were examined at baseline and at 18 months on measures of symptoms (YMRS, HAMD-21, and CGI-S), and social and occupational functioning (SOFAS). Baseline differences between the three groups were determined using general linear models and chi-squared analyses. Group differences from baseline to 18-month follow-up were determined using repeated measures general linear models. At baseline there were significant differences between the three insight groups in terms of mania and functioning, but at 18 months all groups had improved significantly in terms of psychopathology, mania, depression and social and occupational functioning. There were no significant differences between the three groups at study completion with respect to these domains. The study was limited by the lack of availability of a more detailed rating scale for insight, and it did not account for the duration of untreated psychosis (DUI). Poor initial insight during a first episode of mania with psychotic features does not predict poor clinical and psychosocial outcome at 18 months. Crown Copyright © 2014. Published by Elsevier B.V.

The influence of neuroticism on stress perception and its associated negative affect is explored in a quasi-experimental repeated measure study. The study involves manipulating the stress perception and affect of high N group (n = 24) and low N group (n = 28) three times; first, through exposure to neutral stimuli; second, through exposure to a laboratory stressor; third, through exposure to positive stimuli. The results reveal that after exposure to neutral stimuli, there is a significant difference in the baseline Perceived Stress Scores (PSS) (p = .005) and Negative Affect (NA) scores (p = .001) of the two groups. During the stress task, however, both groups show a non-significant difference in the PSS (p = .200) and NA scores (p = .367). After exposure to positive stimuli, there is a significant difference in the PSS scores (p = .001), but a non-significant difference in the NA scores (p = .661) of the two groups. When compared across three conditions, the high N group report significantly higher perceived stress (p = .002), but not significantly higher negative affect (p = .123) than the low N group. Finally for both PSS and NA scores, there is no interaction between neuroticism and any of the three treatment conditions (p = .176; p = .338, respectively). This study shows that the high N group may be at risk for health disparities due to maintaining a chronic higher baseline stress perception and negative affect state under neutral conditions, than the low N group. Implications of the study are discussed.

To investigate the effect of two tinted contact lenses (CL) designed for outdoor sports activity on the psychometric determination of retinal straylight using the compensation comparison method. Thirteen emmetropic subjects were randomly fitted with two different tinted Nike Maxsight (Bausch & Lomb, Rochester, NY, USA) CL in one eye, while the contralateral eye was fitted with a clear lens made of the same material (Optima 38, Bausch & Lomb). Three valid straylight measurements were taken on each eye before and a few minutes after lens insertion, when lens stabilization had occurred. The subjects' mean straylight values were 0.90 +/- 0.09 at baseline and 0.95 +/- 0.10 with the clear Optima 38 CL. Straylight values were 0.97 +/- 0.10 and 1.0 +/- 0.10 log units with the amber and grey-green tinted CL, respectively. Differences in straylight between baseline (without CL) and with the clear CL in place were neither statistically significant (p = 0.066) nor was there a significant difference between baseline and the amber CL (p = 0.052). However, the grey-green CL showed a statistically significant difference from baseline (p = 0.006). Differences in straylight with the clear CL compared with the grey-green CL were also statistically different from zero (p = 0.002) showing an increased straylight value for the tinted CL. These differences were variable, but consistent for each subject, thus those showing higher or lower changes with one tinted lens tended to show the same trend with the second lens (r(2) = 0.736). Despite increases having been found in straylight values with tinted contact lenses, those changes are not likely to induce clinically significant changes in visual function under photopic conditions, even for the grey-green CL, which seems to increase straylight values more significantly than the amber CL. This difference between the tinted CL could suggest a wavelength dependence of straylight values, although this should be investigated further by controlling for pupil size and subjects' pigmentation, as well as by using neutral density filters.

It is still debatable which technique should be used with universal adhesives, either etch-and-rinse (wet or dry) or self-etch strategy (with or without selective enamel etching). To evaluate the 36-month clinical performance of Scotchbond Universal Adhesive (SU, 3M ESPE) in non-carious cervical lesions (NCCLs) using two evaluation criteria. Thirty-nine patients participated in this study. Two-hundred restorations were assigned to four groups: ERm: etch-and-rinse+moist dentin; ERd: etch-and-rinse+dry dentin; Set: selective enamel etching; and SE: self-etch. The same composite resin was inserted for all restorations in up to 3 increments. The restorations were evaluated at baseline and at 6-, 18-, and 36-months using both the FDI and the USPHS criteria. Statistical analyses were performed with Friedman repeated measures ANOVA by rank and McNemar test for significance in each pair (α=0.05). Eight restorations (ERm: 1; ERd: 1; Set: 1 and SE: 5) were lost after 36 months, but only significant for SE when compared with baseline (p=0.02 for either criteria). Marginal staining occurred in 6.8% of the restorations (groups ERm, ERd, and Set) and 17.5% of the restorations (group SE), with significant difference for each group when compared with baseline using the FDI criteria (p<0.04), while statistical significance was reached only for SE when compared with baseline using the USPHS criteria (p<0.03). Twenty-eight and 49 restorations were scored as bravo for marginal adaptation using the USPHS and FDI criteria, respectively, with significant difference for each group when compared with baseline (p<0.05). While there was no statistical difference among bonding strategies when a universal adhesive was used, there were signs of degradation when the universal adhesive was applied in SE mode. The FDI criteria remain more sensitive than the USPHS criteria, especially for the criteria marginal staining and marginal adaptation. Copyright © 2015 Elsevier Ltd. All rights reserved.

Objectives This study assessed the anxiolytic effectiveness of a test diet (Royal Canin Feline Calm diet) supplemented with L-tryptophan and alpha-casozepine. Methods Subjects were 24 cats that were classified as mildly or markedly fearful based on the presence of a person in their home room. Three different protocols were used to assess anxiety: (1) evaluation of the response to a human in the cat's home room (home room test); (2) analysis of the response to placement in an empty test room (open-field test); and (3) analysis of the response to an unfamiliar human (human interaction test). All three protocols were first run at baseline, and the results were used to assign the animals to control and test diet groups that showed equivalent fear and anxiety. Both groups were retested on the three protocols after 2 weeks (test 1) and again after 4 weeks (test 2). Results The diet groups differed for two behavioral measures in the open-field test: inactivity duration and inactivity frequency. The control group showed statistically significant increases in inactivity duration between baseline and test 1 and baseline and test 2, while the group fed the test diet showed a marginally not significant decrease in inactivity duration between baseline and test 1 and a not significant decrease for test 2. There was also a significant increase in inactivity frequency between baseline and test 1 in the test diet group and marginally not significant decrease in the control group. There were no differences between groups in the approach of the cats toward people for the home room test and the human interaction test. Conclusions and relevance These results suggest that the test diet reduced the anxiety response to placement in an unfamiliar location, but that fear in the presence of an unfamiliar person was not counteracted by the diet.

To determine the differences between escitalopram and citalopram in the treatment of patients with major depressive disorder across a range of baseline severity of depression using trend analysis. Data from the three placebo-controlled studies comparing escitalopram to citalopram were analyzed. The pre-specified primary outcome variable was MADRS total score; secondary outcomes included Clinical Global Impression-Severity (CGI-S) and -Improvement (CGI-I) scores. All analyses were based on an intent-to-treat (ITT) population and all direct comparisons were done by ANCOVA adjusting for baseline value and centre. Analyses of the pooled data (N=1203) show that, while the difference between citalopram and placebo was approximately constant across the range of baseline severity, the difference between escitalopram and placebo (p=0.0010 for no trend) and between escitalopram and citalopram (p=0.0012 for no trend) became greater, the more severely depressed the patients were at baseline. A similar pattern was apparent with the CGI-S and CGI-I results. There was a significant superiority of escitalopram over citalopram in response rate (defined as > or = 50% decrease in MADRS total score), and this difference increased with increasing baseline severity. These trend analyses thus indicate that the superiority of escitalopram over citalopram is more apparent as the baseline severity of depression increases.

The Southeastern United States has the highest prevalence of hypertension and African Americans have disproportionately worse blood pressure control. The authors sought to evaluate the effect of a multicomponent practice-based quality improvement intervention on lowering mean systolic blood pressure (SBP) at 12 and 24 months compared with baseline among 525 patients, and to assess for a differential effect of the intervention by race (African Americans vs white). At 12 months, both African Americans (-5.0 mm Hg) and whites (-7.8 mm Hg) had a significant decrease in mean SBP compared with baseline, with no significant between-group difference. Similarly, at 24 months, mean SBP decreased in both African Americans (-6.0 mm Hg) and whites (-7.2 mm Hg), with no significant difference between groups. Notably, no significant racial disparity in mean SBP at baseline was shown. The intervention was effective in lowering mean SBP in both African Americans and whites but there was no differential effect of the intervention by race. ©2016 Wiley Periodicals, Inc.

Sublingual-specific immunotherapy (SLIT) is considered as a valid treatment of respiratory allergies. We performed a case-control study to evaluate the effect of SLIT in children with allergic asthma and rhinitis. The study plan included 140 patients (age 6-14 yr, 43% girls and 57% boys) presenting allergic rhinitis and/or asthma, 70 treated with SLIT actively for three years and 70 controls never treated with specific immunotherapy (only symptomatic drugs). Rhinitis Symptom Score (RSS), Asthma Symptom Score (ASS) and Medication Score (MS) were evaluated at beginning and during the 3 years of immunotherapy. results: There was a significant improvement of RSS (mean ± SD) in the SLIT group: baseline 5.31 ± 2.01, third year 1.38 ± 1.06 (p < 0.0001 vs baseline). baseline 5.00 ± 1.08, third year 4.68 ± 1.152 (P ¼ NS). ASS (mean ± SD) in the SLIT group: baseline 4.09 ± 2.21, third year 1.23 ± 1.4 (p < 0.0001 vs baseline). baseline 4.04 ± 2.46, third year 3.62 ± 2.26 (p ¼ NS). MS (mean ± SD) in the SLIT group: baseline 3.30 ± 1.4, third year 0.88 ± 1.26 (p < 0.0001 vs baseline). baseline 3.19 ± 1.23, third year 3.39 ± 1.12 (p ¼ NS). There are no statistically significant differences among monosensitized/polysensitized patients and at different age ranges. None of the patients included reported severe systemic reactions or anaphylaxis. During the treatment, the active group showed sustained reductions in mean asthma and rhinitis symptom scores when compared with controls to confirm the efficacy and safety of sublingual immunotherapy.

Obstructive sleep apnoea (OSA) is strongly associated with cardiovascular disease. However, acute cardiovascular effects of repetitive airway obstruction are poorly understood. While past research used a sustained Mueller manoeuver to simulate OSA we employed a series of gasping efforts to better simulate true obstructive apnoeas. This report describes acute changes in cardiac anatomy and flow related to sudden changes in intrathoracic pressure. 26 healthy, normal weight participants performed 5-6 gasping efforts (target intrathoracic pressure -40 mm Hg) while undergoing Doppler echocardiography. 14 participants had sufficient echocardiographic images to allow comparison of atrial areas during the manoeuver with baseline measurements. Mitral and tricuspid E-wave and A-wave velocities postmanoeuver were compared with baseline in all participants. Average atrial areas changed little during the manoeuver, but variance in both atrial areas was significantly greater than baseline. Further, an inverse relationship was noted with left atrial collapse and right atrial enlargement at onset of inspiratory effort. Significant inverse changes were noted in Doppler flow when comparing the first beat postmanoeuver (pMM1) with baseline. Mitral E-wave velocity increased 9.1 cm/s while tricuspid E-wave velocity decreased 7.0 cm/s; by the eighth beat postmanoeuver (pMM8) values were not different from baseline. Mitral and tricuspid A-wave velocities were not different from baseline at pMM1, but both were significantly higher by pMM8. Repetitive obstructive apnoeas produce dynamic, inverse changes in atrial size and Doppler flow across the atrioventricular valves. These observations have important implications for understanding the pathophysiology of OSA.

Outcomes in a RCTs of 12 weeks of theclinical efficacy of N-acetylcysteine (NAC) as an adjunctive treatment on depression and anxiety symptoms and its effects on high-sensitivity C-reactive protein (hs-CRP) levels. A wide array of measures were made. The 17-item version of the Hamilton Depression Rating Scale (HDRS17); the Hamilton Anxiety Rating Scale (HAM-A); Sheehan Disability Scale; Quality of Life; Clinical Global Impression (CGI); anthropometrics measures; and vital signs and biochemical laboratory. There were no significant differences among the groups regarding demographic, clinical features, use of medication, metabolic syndrome and comorbidities. From baseline to week 12, individuals receiving NAC, versus placebo, had a statistically significant reduction in depressive symptoms on HDRS 17 (p < 0.01) and anxiety symptoms on HAM-A (p = 0.04), but only for individuals with levels of hs-CRP > 3 mg/L at baseline. Individuals receiving NAC with baseline levels of hs-CRP > 3 mg/L, had more significant reduction in uric acid levels compared to individuals with baseline levels of hs-CRP ≤ 3 mg/L on week 12. Participants receiving placebogained significantly more weight during the 12 weeks for baseline levels of hs-CRP ≤ 3 mg/L and hs-CRP > 3 mg/L, and individuals receiving NAC in both groups did not have significant weight change during the 12 weeks. No individuals were withdrawn from the study because of adverse event. NAC group exhibited significantly greater reduction on hs-CRP levels than placebo group from baseline to week 12. clinicaltrials.gov Identifier; NCT02252341. Copyright © 2018 Elsevier B.V.

Chinese American women with type 2 diabetes (T2DM) are more vulnerable to poor diabetes outcomes than men because immigrant status, ethnicity, and economics intersect with gender to diminish disease management opportunities. We explored gender differences in factors associated with diabetes management at intake and after treatment with a behavioral intervention in first-generation Chinese American immigrants. A sample of 178 Chinese Americans with T2DM was enrolled in a single-cohort, repeated-measures delayed-treatment trial. Data were collected at baseline, 8, 16, 24, and 32 weeks with 6-week treatment provided after 16 weeks. Gender differences at baseline and gender by treatment interactions were noted. Women at baseline reported significantly worse depressive symptoms and general health. Significant gender by treatment interactions were observed for diabetes self-efficacy, bicultural efficacy, family instrumental support, and diabetes quality of life-satisfaction. Only women showed improvement, suggesting women benefited more from the intervention in psychosocial factors related to diabetes management. © The Author(s) 2014.

Different attachment systems for mandibular two-implant overdentures could influence levels of patient satisfaction. Positive consensus of the majority of patients being satisfied does not preclude the possibility of dissatisfaction for some. To evaluate patient satisfaction and dissatisfaction before and after 5 years of wearing mandibular two implant overdentures using different attachment systems ; to determine the prognostic relevance of pretreatment complete denture complaints to treatment outcomes. A total of 106 edentulous participants enrolled in a clinical trial completed a preliminary self-report inventory of their original complete denture complaints.New complete maxillary dentures and mandibular two-implant overdentures were provided to each participant using one of six different attachment systems. Patient satisfaction was determined at pretreatment; at baseline with mandibular two-implant overdenture insertion; and then annually for 5 years, using visual analogue and Likert-type scales. Patient satisfaction with mandibular two-implant overdentures showed significant changes pre- to posttreatment(baseline) in all domains, but these were significant immediately and maintained without further significance for 5 years, other than pain with the overdenture. After 5 years, no significant differences were observed with all the attachment systems. Highly significant differences were found with some social and psychological aspects by the fifth year compared to baseline. Diagnostic and prognostic indicators from a pretreatment inventory identified 12 participants (13.5%) who were dissatisfied. These indicators revealed a maladaptive predisposition to mandibular two-implant overdentures. The provision of mandibular two-implant overdentures will, in the majority of patients, significantly enhance levels of patient satisfaction for 5 years, as compared to complete mandibular dentures, regardless of the attachment system. Careful evaluation of pretreatment complaints with conventional dentures can possibly identify patient dissatisfaction with mandibular two-implant overdentures [corrected]. © 2010 Wiley Periodicals, Inc.

The effect of heat-pressing and subsequent pre-cementation (acid-etching) and resin-cementation operative techniques on the development of transient and residual stresses in different thicknesses of a lithium disilicate glass-ceramic were characterised using profilometry prior to biaxial flexure strength (BFS) determination. 60 IPS e.max Press discs were pressed and divested under controlled conditions. The discs were polished on one surface to thicknesses of 0.61±0.05, 0.84±0.08, and 1.06±0.07 mm (Groups A-C, respectively). The mean of the maximum deflection (acid-etching and resin-coating was determined using high resolution profilometery prior to BFS testing. Paired sample t-tests were performed (p<0.05) on the 20 individual samples in each group (Groups A-C) for each comparison. Differences between the baseline quantification and resin-cement coating deflection values and BFS values for Groups A-C were determined using a one-way ANOVA with post hoc Tukey tests (p<0.05). Baseline quantification for Groups A-C identified no significant differences between the group means of the maximum deflection values (p=0.341). Following HF acid-etching, a significant increase in deflection for all groups (p<0.001) was identified compared with the baseline quantification. Additionally, resin-cement coating significantly increased deflection for Group A (p<0.001), Group B (p<0.001) and Group C (p=0.001) specimens for the individual groups. The increased deflection from baseline quantification to resin-cement coating was significantly different (p<0.001) for the three specimen thicknesses, although the BFS values were not. The lower reported baseline quantification range of the mean of the maximum deflection for the IPS e.max(®) Press specimens was predominantly the result of specimen polishing regime inducing a tensile stress state across the surface defect integral which accounted for the observed surface convexity. Acid-etching and resin-cementation had a significant impact on the development and magnitude of the transient and residual stresses in the lithium disilicate glass-ceramic investigated.

Objective: To assess the effect of angiotensin converting enzyme inhibition on glomerular filtration rate (GFR) in normotensive patient with type 1 diabetes. Methods: A two year non-placebo control prospective study was conducted after ethical approval at Diabetes Centre of Diabetic Association of Pakistan, a WHO collaborating centre in Karachi, Pakistan. All patients with type 1 diabetes visited the out-patients department from August 2009 till July 2011 and those who fulfilled the inclusion criteria were invited to participate. A total of 121 people aged ≥18 years and ≥ 5 years of diabetes were included. Pregnant and lactating woman and those aged <18 years were excluded. GFR was calculated by using CKD-EPI formula (eGFR) at baseline and after two year. On the basis of estimated GFR, patients at baseline were divided according to KDIGO classification of chronic kidney diseases into, hyperfiltration (eGFR ≥ 100 ml/min) and normal filtration group (eGFR < 100 ml/min). All subjects in hyperfiltration group received ACE inhibitor (treatment group) while patients with normal filtration did not receive ACE inhibitor (control group). Results: Fifty two patients (43%) were in the treatment and sixty nine (57%) were in the control group. At baseline eGFR, systolic and diastolic blood pressures between groups were non-significantly different. After two years, compared to baseline, eGFR of the treatment group declined and the control group increased significantly. No significant difference in systolic while diastolic blood pressure of the treatment group increased significantly after two years compared to baseline. In contrast both systolic and diastolic blood pressure of control group increased significantly after two years compared to their baseline values. Conclusion: Present study demonstrated that initiation of ACEI in hyperfiltration stage declined GFR and keep blood pressure within normal range. PMID:27375689

The aim of the present study was to compare the long-term effects of two dietary approaches on changes in dietary intakes, eating behaviours and body weight: (1) approach using restrictive messages to limit high-fat foods (low-fat intake; LOFAT); (2) approach emphasising non-restrictive messages directed towards the inclusion of fruits and vegetables (high intake of fruits and vegetables; HIFV). A total of sixty-eight overweight or obese postmenopausal women were randomly assigned to one of the two dietary approaches. The 6-month dietary intervention included three group sessions and ten individual sessions with a dietitian. Dietary intakes, eating behaviours and anthropometrics were measured at baseline, at the end of the dietary intervention (T = 6) and 6 months and 12 months after the end of the intervention (T = 12 and T = 18). In the LOFAT group, energy and fat intakes were lower at T = 6 when compared with baseline and remained lower at T = 12 and T = 18. In the HIFV group, fruit and vegetable intakes increased significantly at T = 6 but were no longer significantly different from baseline at T = 12 and T = 18. Dietary restraint increased at T = 6 and remained higher than baseline at T = 18 in the LOFAT group while no significant change was observed in the HIFV group. At T = 6, body weight was significantly lower than baseline in both groups (LOFAT: - 3.7 (SD 2.8) kg; HIFV: - 1.8 (SD 3.0) kg) and no significant difference in body-weight change from baseline was found between groups at T = 18. We concluded that weight loss was similar at 1-year follow-up in both dietary approaches. Despite relatively good improvements in the short term, the adherence to a 6-month dietary intervention promoting high intakes of fruits and vegetables was difficult to maintain.

Background Airway inflammation is a significant contributor to the morbidity of cystic fibrosis (CF) disease. One feature of this inflammation is the production of oxygenated metabolites, such as prostaglandins. Individuals with CF are known to have abnormal metabolism of fatty acids, typically resulting in reduced levels of linoleic acid (LA) and docosahexaenoic acid (DHA). Methods This is a randomized, double-blind, cross-over clinical trial of DHA supplementation with endpoints of plasma fatty acid levels and prostaglandin E metabolite (PGE-M) levels. Patients with CF age 6 to 18 years with pancreatic insufficiency were recruited. Each participant completed 3 four-week study periods: DHA at two different doses (high dose and low dose) and placebo with a minimum 4 week wash-out between each period. Blood, urine, and exhaled breath condensate (EBC) were collected at baseline and after each study period for measurement of plasma fatty acids as well as prostaglandin E metabolites. Results Seventeen participants were enrolled, and 12 participants completed all 3 study periods. Overall, DHA supplementation was well tolerated without significant adverse events. There was a significant increase in plasma DHA levels with supplementation, but no significant change in arachidonic acid (AA) or LA levels. However, at baseline, AA levels were lower and LA levels were higher than previously reported for individuals with CF. Urine PGE-M levels were elevated in the majority of participants at baseline, and while levels decreased with DHA supplementation, they also decreased with placebo. Conclusions Urine PGE-M levels are elevated at baseline in this cohort of pediatric CF patients, but there was no significant change in these levels with DHA supplementation compared to placebo. In addition, baseline plasma fatty acid levels for this cohort showed some difference to prior reports, including higher levels of LA and lower levels of AA, which may reflect changes in clinical care, and consequently warrants further investigation.

This randomized clinical trial investigated the influence of the utilization time of brush heads from different types of power toothbrushes [oscillating rotating (OR) and sonic action (SA)93; on oral hygiene (plaque accumulation and gingival inflammation) over a 6-month observation period. 49 participants were randomly allocated into two groups: use of the same brush head over 6 months (NR: non-replacement) or replacement of brush head every 4 weeks over 6 months (R: replacement). Each group was subdivided into two subgroups according to kind of toothbrush (TB) used (OR and SA). Modified Quigley-Hein plaque index (QHI), papilla bleeding index (PBI), and gingival index (GI) were recorded at baseline and 2, 8, 12, 16, and 24 weeks after baseline. After 24 weeks, participants of both groups (R and NR) received a new brush head. At week 26, final QHI, PBI, and GI were recorded. QHI decreased between baseline and follow-up visits in R groups (P< 0.05), with the exception of week 12 (P= 0.26). In NR groups, no significant decrease was detected (P> 0.05). There was no significant effect of time on PBI or GI in any of R subgroups (P> 0.05). In NR oscillating/rotating TB: significant increase in PBI and GI was detected 24 weeks after baseline (PBI: P= 0.02, GI: P= 0.03); sonic action TBs showed significant decrease in PBI at every follow-up visit (P< 0.05), except at 24 weeks after baseline (P= 0.73). GI was significantly decreased at 2 weeks after baseline only (P< 0.01). Six-month use of the same brush head reduced effectiveness in removing plaque, and gingival inflammation appeared to increase after a utilization time of over 4 months. Replacing brush heads is advised after 4 months.

To determine the effect of sedation with detomidine on intraocular pressure (IOP) in standing horses and whether topical ocular application of anesthetic alters this effect. Clinical trial. 15 clinically normal horses. Horses were assigned to group 1 (n = 7) or 2 (8). Intraocular pressure measurements were obtained at baseline (before sedation) and 10 minutes after IV administration of detomidine (0.02 mg/kg [0.009 mg/lb]). Group 1 horses had an additional IOP measurement at 20 minutes after sedation. For group 2 horses, topical ocular anesthetic was administered 10 minutes prior to baseline IOP measurements. Mean ± SD baseline IOP for horses without topical anesthesia (group 1 horses; IOP, 24.30 ± 3.09 mm Hg) was significantly lower, compared with that of horses with topical anesthesia (group 2 horses; IOP, 30.40 ± 3.25 mm Hg). Compared with baseline values, IOP at 10 minutes after sedation decreased significantly in all horses (by 3.61 ± 1.48 mm Hg and 5.78 ± 4.32 mm Hg in groups 1 and 2, respectively). In group 1 horses, IOP at 10 (20.69 ± 3.45 mm Hg) and 20 (19.96 ± 2.13 mm Hg) minutes after sedation was significantly decreased, compared with baseline values; however, the difference between IOP at 10 versus 20 minutes was not significant. The difference in IOP between group 1 and 2 horses at 10 minutes after sedation was not significant. IV administration of detomidine caused a decrease in IOP in clinically normal horses and may be a safe sedative when performing ocular procedures.

To investigate the effect(s) of intravitreally injected ranibizumab on retinal vessel diameter in patients with diabetic macular edema. Participants of this prospective study were 14 men and 16 women (30 eyes) aged 60 ± 11 years (mean ± standard deviation), all with clinically significant diabetic macular edema. Treatment comprised 3 intravitreal injections of ranibizumab given at 4-week intervals. Examinations were conducted before the first (baseline), before the second (Month 1), before the third (Month 2) injections, and 3 months after baseline (Month 3). Measured parameters included systemic blood pressure, static retinal vessel analysis (central retinal artery equivalent and central retinal vein equivalent), and dynamic retinal vessel analysis, as measured by the change in vessel diameter in response to flicker stimulation during three measurement cycles. Flicker stimulation was accomplished using a 50-second baseline recording, followed by an online measurement during 20-second flicker stimulation and 80-second online measurements in both arteriolar and venular vessel segments. Static retinal vessel analysis showed a reduction of central retinal artery equivalent from 186.25 ± 51.40 μm (baseline) to 173.20 ± 22.2 μm (Month 1), to 174.30 ± 27.30 μm (Month 2), and to 170.56 ± 22.89 μm (Month 3), none of which was statistically significant (P = 0.23, 0.12, and 0.14, respectively). Central retinal vein equivalent was reduced from 216.21 ± 25.0 μm (baseline) to 214.48 ± 25.4 μm (Month 1), to 214.80 ± 24.30 μm (Month 2), and to 211.41 ± 24.30 μm (Month 3), revealing no statistically significant differences between examination time points (P = 0.54, 0.06, and 0.24, respectively). Dynamic vessel analysis yielded a mean retinal arterial diameter change of +1.47% ± 2.3 (baseline), +1.91% ± 2.5 (Month 1), +1.76% ± 2.2 (Month 2), and +1.66% ± 2.1 (Month 3), none of which showed statistically significant differences (P = 0.32, 0.49, and 0.70, respectively). Mean retinal venous diameter changes were +3.15% ± 1.7 (baseline), +3.7% ± 2.3 (Month 1), +4.0% ± 2.0 (Month 2), and +4.95% ± 1.9 (Month 3), none of which showed statistically significant differences (P = 0.12, 0.17, and 0.14, respectively). Central retinal thickness, as measured by spectral domain optical coherence tomography, decreased significantly from 435.2 ± 131.8 μm (baseline) to 372.3 ± 142.8 μm (Month 3), P = 0.01. Regression analysis of arteriolar and venular diameters indicated that there was no significant correlation between these 2 parameters (r = 0.053; P = 0.835 and r = 0.06; P = 0.817, respectively). Also, no significant correlation was observed between the difference in the central retinal thickness and change in arteriolar or venular dilatation (r = 0.291, P = 0.241 and r = 0.06, P = 0.435, respectively). Intravitreally applied ranibizumab did not significantly affect retinal vessel diameter in patients with diabetic macular edema. Decline in the central foveal thickness after ranibizumab therapy, as measured by spectral domain optical coherence tomography, was not linked to any change in retinal vessel diameter or dilatatory response, neither for arterioles nor venules.

Background Protein supplements are routinely used after a laparoscopic gastric bypass (LGB). The aim of this study is to evaluate the impact of an amino acid supplement on glucose homeostasis, hormonal and inflammatory markers after LGB. Methods 30 patients undergoing LGB were randomized to receive or not to receive 24g of an oral supplement containing a leucine metabolite, glutamine and arginine twice daily for 8 weeks. Changes in weight, BMI, ghrelin, GLP-1, GIP, glucose, insulin, C-peptide, insulin sensitivity, IL-6, CRP, leptin and IGF-1 were assessed preoperatively, 2 weeks and 8-weeks postoperatively. Results 30 patients (96.7% females, 46.9 ± 8.4 years, 113.4 ± 11.6 kg and BMI 43.3 ± 4.1 kg/m2) were randomized. The experimental (N=14) and control groups (N=16) were not significantly different at baseline. Weight and BMI were decreased significantly at two weeks and at eight weeks (p<0.0001 for each variable), but no statistical significance was observed between the two groups. Fasting glucose decreased significantly at 2 & 8 weeks as compared to base line (p<0.0001) with no difference between experimental and control groups (p=0.8), but insulin and calculated insulin sensitivity, that were similar at baseline, become significantly worse in the experimental group 8 weeks after surgery ( p=0.02 for insulin, p=0.04 for the homeostasis model assessment (HOMA) index). CRP, which was similar at baseline, was found to be significantly lower at 8 weeks in control vs. experimental group, (P=0.018). IL-6 decreased significantly from baseline at 2 weeks and rebounded at 8 weeks in both groups, there was a trend of higher IL-6 in the experimental group that becomes significant at 8 weeks (p=0.05). Leptin and IGF-1 levels decreased significantly from baseline at 2 & 8 weeks (p<0.0001) but there was no difference between the two groups. No significant change in GLP-1, ghrelin or GIP were noticed after 8 weeks. Conclusion An amino acid supplement had no effect on the early postoperative incretins following LGB. It may have a negative influence on glycemic control and degree of inflammation. Future studies are needed to clarify these effects. PMID:21463799

To investigate whether the proven benefits of insulin degludec (IDeg) combined with insulin aspart (IAsp), known as IDegAsp, given twice daily, extend across a wide spectrum of patients with diabetes. This was a post hoc pooled analysis of 5 phase III randomized, 26-week, open-label, treat-to-target trials comparing IDegAsp twice daily (n = 1111) with one of two comparators: premixed insulin (biphasic insulin aspart 30 [BIAsp 30]) twice daily (n = 561) or IDeg once daily + IAsp (n = 136). Patient data were stratified according to baseline glycated haemoglobin (HbA1c) or fasting plasma glucose (FPG) categories, as well as by baseline duration of diabetes or body mass index (BMI) categories. We conducted a meta-analysis of 5 clinical trials: NCT01513590, NCT01009580, NCT01059812, NCT01680341 and NCT01713530. End-of-trial results were broadly consistent, with differences between IDegAsp and comparators observed in phase III trials. HbA1c results were similar for IDegAsp and the comparators in all baseline characteristic (HbA1c, duration of diabetes or BMI) and category groups (number ranges). Significantly lower FPG level was observed with IDegAsp vs comparators in all baseline characteristic and most category groups (excluding FPG <5.5 mmol/L). Significantly lower insulin doses were observed with IDegAsp vs comparators in all baseline characteristic and half of the category groups, and significantly lower rates of confirmed and nocturnal confirmed hypoglycaemia were observed with IDegAsp vs comparators in all baseline variable and category groups. IDegAsp retains a consistent safety and efficacy profile in patients with different baseline characteristics. © 2018 The Authors. Diabetes, Obesity and Metabolism published by John Wiley & Sons Ltd.

(R,S)-ketamine is a rapid and effective antidepressant drug that produces a response in two thirds of patients with treatment-resistant depression (TRD). The underlying biochemical differences between a (R,S)-ketamine responder (KET-R) and non-responder (KET-NR) have not been definitively identified but may involve serine metabolism. The aim of the study was to examine the relationship between baseline plasma concentrations of D-serine and its precursor L-serine and antidepressant response to (R,S)-ketamine in TRD patients. Plasma samples were obtained from 21 TRD patients at baseline, 60 min before initiation of the (R,S)-ketamine infusion. Patients were classified as KET-Rs (n = 8) or KET-NRs (n = 13) based upon the difference in Montgomery-Åsberg Depression Rating Scale (MADRS) scores at baseline and 230 min after infusion, with response defined as a ≥50 % decrease in MADRS score. The plasma concentrations of D-serine and L-serine were determined using liquid chromatography-mass spectrometry. Baseline D-serine plasma concentrations were significantly lower in KET-Rs (3.02 ± 0.21 μM) than in KET-NRs (4.68 ± 0.81 μM), p < 0.001. A significant relationship between baseline D-serine plasma concentrations and percent change in MADRS at 230 min was determined using a Pearson correlation, r = 0.77, p < 0.001, with baseline D-serine explaining 60 % of the variance in (R,S)-ketamine response. The baseline concentrations of L-serine (L-Ser) in KET-Rs were also significantly lower than those measured in KET-NRs (66.2 ± 9.6 μM vs 242.9 ± 5.6 μM, respectively; p < 0.0001). The results demonstrate that the baseline D-serine plasma concentrations were significantly lower in KET-Rs than in KET-NRs and suggest that this variable can be used to predict an antidepressant response following (R,S)-ketamine administration.
Comparative efficacy of two battery-powered toothbrushes on dental plaque removal.

A number of clinical studies have consistently demonstrated that power toothbrushes deliver superior plaque removal compared to manual toothbrushes. Recently, a new power toothbrush (Crest SpinBrush) has been marketed with a design that fundamentally differs from other marketed power toothbrushes. Other power toothbrushes feature a small, round head designed to oscillate for enhanced cleaning between the teeth and below the gumline. The new power toothbrush incorporates a similar round oscillating head in conjunction with fixed bristles, which allows the user to brush with optimal manual brushing technique. The objective of this randomized, examiner-blind, parallel design study was to compare the plaque removal efficacy of a positive control power toothbrush (Colgate Actibrush) to an experimental toothbrush (Crest SpinBrush) following a single use among 59 subjects. Baseline plaque scores were 1.64 and 1.40 for the experimental toothbrush and control toothbrush treatment groups, respectively. With regard to all surfaces examined, the experimental toothbrush delivered an adjusted (via analysis of covariance) mean difference between baseline and post-brushing plaque scores of 0.47, while the control toothbrush delivered an adjusted mean difference of 0.33. On average, the difference between toothbrushes was statistically significant (p = 0.013). Because the covariate slope for the experimental group was statistically significantly greater (p = 0.001) than the slope for the control group, a separate slope model was used. Further analysis demonstrated that the experimental group had statistically significantly greater plaque removal than the control group for baseline plaque scores above 1.43. With respect to buccal surfaces, using a separate slope analysis of covariance, the experimental toothbrush delivered an adjusted mean difference between baseline and post-brushing plaque scores of 0.61, while the control toothbrush delivered an adjusted mean difference of 0.39. This difference between toothbrushes was also statistically significant (p = 0.002). On average, the results on lingual surfaces demonstrated similar directional scores favoring the experimental toothbrush; however these results did not achieve statistical significance. In conclusion, the experimental Crest SpinBrush, with its novel fixed and oscillating bristle design, was found to be more effective than the positive control Colgate Actibrush, which is designed with a small round oscillating cluster of bristles.

Evidence in adults suggests that improvements in cognitive performance may follow weight loss resulting from bariatric surgery, and baseline cognitive performance may be associated with weight loss following surgery. This has not been evaluated in adolescents. Participants were 38 adolescents of age 14-21 years composed of three groups: (1) 12 adolescents with severe obesity who received vertical sleeve gastrectomy during the study (VSG); (2) 14 adolescents with severe obesity who were wait-listed for VSG (WL); and (3) 12 healthy weight controls (HC). Participants completed testing of visual memory, verbal memory, and executive functioning at baseline (T1), which occurred presurgery for the VSG group, and approximately 4 months after baseline (T2). Body mass index (BMI) was assessed at T1, T2, and additionally at 6 months following VSG for the adolescents who received surgery. Although there was evidence of greater improvement for the VSG as compared with WL and HC groups in visual and verbal memory, group differences did not reach significance and effect sizes were small (η2 < 0.01). There was a significant positive association between indices of baseline executive functioning and excess BMI loss at 6 months postsurgery. This small pilot study showed no significant differences by group in cognitive performance post-VSG. There was a significant association of baseline cognitive performance with weight loss outcomes. Given the very preliminary nature of these results in a small sample, future research should examine these relationships in a larger sample and evaluate mechanisms of these associations (e.g., insulin resistance, sleep, physical activity).

Corticomotor excitability has been shown to correlate with motor learning and functional recovery. The aim of the present study was to monitor changes in excitability of the corticomotor pathways induced by neck training and to compare the effects in patients with neck or knee pain and pain-free participants. Corticomotor excitability was assessed using transcranial magnetic stimulation and electromyography at baseline, after 30 min and 1 h, and at a 1-week follow-up visit. The primary outcome measures were changes in amplitudes and latencies of motor evoked potentials (MEPs) at 1-week follow-up. MEP responses induced by neck training yielded significantly different outcomes in the three groups. In the group with neck pain and training, MEP amplitudes were significantly reduced between baseline and 30 min (p ≤ 0.05), but with no significant difference between baseline, 1 h (p = 0.178) and 1 week (p = 0.067). In the group with knee pain and training, MEP amplitudes significantly increased between baseline and 30 min (p ≤ 0.01) and 1 h (p < 0.001), but not after 1 week (p = 0.524) compared with baseline. In the pain-free group, there were no changes over time. Neck training reduced neuroplastic responsiveness of corticomotor pathways in neck pain patients in contrast to knee pain patients and pain-free participants. Increased attention to adaptive and maladaptive neuroplastic responses induced by training may prove valuable in the process of optimizing clinical outcomes. © 2014 European Pain Federation - EFIC®

Myalgic Encephalopathy/Chronic Fatigue Syndrome (ME/CFS) is a disease of unknown etiology. We have previously suggested clinical benefit from B-cell depletion using the monoclonal anti-CD20 antibody rituximab in a randomized and placebo-controlled study. Prolonged responses were then demonstrated in an open-label phase-II study with maintenance rituximab treatment. Using blood samples from patients in the previous two clinical trials, we investigated quantitative changes in T-lymphocyte subsets, in immunoglobulins, and in serum levels of two B-cell regulating cytokines during follow-up. B-lymphocyte activating factor of the tumor necrosis family (BAFF) in baseline serum samples was elevated in 70 ME/CFS patients as compared to 56 healthy controls (p = 0.011). There were no significant differences in baseline serum BAFF levels between patients with mild, moderate, or severe ME/CFS, or between responders and non-responders to rituximab. A proliferation-inducing ligand (APRIL) serum levels were not significantly different in ME/CFS patients compared to healthy controls at baseline, and no changes in serum levels were seen during follow-up. Immunophenotyping of peripheral blood T-lymphocyte subsets and T-cell activation markers at multiple time points during follow-up showed no significant differences over time, between rituximab and placebo groups, or between responders and non-responders to rituximab. Baseline serum IgG levels were significantly lower in patients with subsequent response after rituximab therapy compared to non-responders (p = 0.03). In the maintenance study, slight but significant reductions in mean serum immunoglobulin levels were observed at 24 months compared to baseline; IgG 10.6-9.5 g/L, IgA 1.8-1.5 g/L, and IgM 0.97-0.70 g/L. Although no functional assays were performed, the lack of significant associations of T- and NK-cell subset numbers with B-cell depletion, as well as the lack of associations to clinical responses, suggest that B-cell regulatory effects on T-cell or NK-cell subsets are not the main mechanisms for the observed improvements in ME/CFS symptoms observed in the two previous trials. The modest increase in serum BAFF levels at baseline may indicate an activated B-lymphocyte system in a subgroup of ME/CFS patients.

Some clinical studies have reported reduced peripheral glial cell line-derived neurotrophic factor (GDNF) level in elderly patients with major depressive disorder (MDD). We verified whether a reduction in plasma GDNF level was associated with MDD. Plasma GDNF level was measured in 23 healthy control subjects and 23 MDD patients before and after 6 weeks of treatment. Plasma GDNF level in MDD patients at baseline did not differ from that in healthy controls. Plasma GDNF in MDD patients did not differ significantly from baseline to the end of treatment. GDNF level was significantly lower in recurrent-episode MDD patients than in first-episode patients before and after treatment. Our findings revealed significantly lower plasma GDNF level in recurrent-episode MDD patients, although plasma GDNF levels in MDD patients and healthy controls did not differ significantly. The discrepancy between our study and previous studies might arise from differences in the recurrence of depression or the ages of the MDD patients.

This study is designed to investigate the inducing effect of one arm exercise on interarm difference (IAD) in the blood pressure (BP). Fifty healthy young participants were included in the study. Three-minute exercises of the right arm elbow flexion and extension were performed. The bilateral brachial BP was simultaneously measured with two automatic BP measurement devices before (basic) and immediately 0, 5, 10, 15, 20, and 30 min after exercise. The absolute difference in the systolic BP (SBP) and diastolic BP (DBP) between the left and right BP of at least 10 mmHg was recognized as sIAD and dIAD. The baseline data of the SBP and DBP in left and right arms revealed no significant difference (SBP: 110 ± 10 vs. 111 ± 11 mmHg; DBP: 66 ± 8 vs. 66 ± 9 mmHg, both not significant). The prevalence of dIAD was 2% at the baseline. However, this prevalence increased to 80% at 0 min, as right arm exercise induced the right DBP decrease and left DBP increase, and then the prevalence decreased gradually within a 30-min recovery period. The prevalence of sIAD was zero at the baseline and the maximal prevalence was 8% during the 20-min postexercise period. One arm exercise can lead to a significant IAD in DBP. Any arm exercise should be avoided before BP measurement.

Personal hygiene related diseases are serious public health problems in developing countries. To assess the effect of health education on knowledge, attitude, and practices of personal hygiene among rural secondary school students in Sokoto state, north western Nigeria. A quasi-experimental controlled study with pretest and post-test design was carried out. A total 120 subjects per group were selected by multistage sampling technique. Two pre-tested instruments, structured interviewer-administered questionnaire and observer's checklist for personal hygiene practices were used for data collection. Health education intervention was carried out one week after baseline data collection and repeated after four weeks for the intervention group only. Postintervention data collection was carried out in both intervention and control groups three months after the 2nd intervention. However, for ethical consideration, the control group was also provided with the health education intervention similar to that provided to the intervention group. A total of 120 and 116 subjects in the intervention and control groups respectively participated in all phases of the study. The mean knowledge score (%) of the study subjects was high and similar (73.18 +/- 25.82; 77.06 +/- 21.79; p = 0.21) in both the intervention and control groups at baseline, but differed very significantly (91.16 +/- 11.03; 81.74 +/- 21.78; p < 0.0001) at post-intervention. The mean attitude score (%) was high but differ significantly (82.6 +/- 12.73; 86.38 +/- 10.74; p = 0.01) between the intervention and control groups at baseline, and further differed very significantly (95.5 +/- 3.66; 86.90 +/- 10.44; p < 0.0001) at post intervention. The mean reported practice score (%) was high but differ significantly (94.86 +/- 3.00; 93.25 +/- 6.31; p = 0.01) between the intervention and control groups at baseline, and further differed very significantly (96.68 +/- 4.08; 93.7 +/- 6.28; p < 0.0001) at post-intervention. The mean observed practice score (%) was high and similar (57.50 +/- 29.65; 61.35 +/- 28.49; p = 0.31) in both the intervention and control groups at baseline, but differed very significantly (88.20 +/- 9.99; 62.10 +/- 26.94; p < 0.0001) at post-intervention. Health education intervention had impact on knowledge base, attitude and practice of study subjects in intervention group compared to control group. Personal hygiene health education is therefore recommended to be taught in secondary schools.

Computerized neuropsychological tests are frequently used to assist in return-to-play decisions following sports concussion. However, due to concerns about test reliability, the Centers for Disease Control and Prevention recommends yearly baseline testing. The standard practice that has developed in baseline/postinjury comparisons is to examine the difference between the most recent baseline test and postconcussion performance. Drawing from classical test theory, the present study investigated whether temporal stability could be improved by taking an alternate approach that uses the aggregate of 2 baselines to more accurately estimate baseline cognitive ability. One hundred fifteen English-speaking professional hockey players with 3 consecutive Immediate Postconcussion Assessment and Testing (ImPACT) baseline tests were extracted from a clinical program evaluation database overseen by the National Hockey League and National Hockey League Players' Association. The temporal stability of ImPACT composite scores was significantly increased by aggregating test performance during Sessions 1 and 2 to predict performance during Session 3. Using this approach, the 2-factor Memory (r = .72) and Speed (r = .79) composites of ImPACT showed acceptable long-term reliability. Using the aggregate of 2 baseline scores significantly improves temporal stability and allows for more accurate predictions of cognitive change following concussion. Clinicians are encouraged to estimate baseline abilities by taking into account all of an athlete's previous baseline scores.

Mathematical performance is highly correlated with several general cognitive abilities, including working memory (WM) capacity. Here we investigated the effect of numerical training using a number-line (NLT), WM training (WMT), or the combination of the two on a composite score of mathematical ability. The aim was to investigate if the combination contributed to the outcome, and determine if baseline performance or neuroimaging predict the magnitude of improvement. We randomly assigned 308, 6-year-old children to WMT, NLT, WMT+NLT or a control intervention. Overall, there was a significant effect of NLT but not WMT. The WMT+NLT was the only group that improved significantly more than the controls, although the interaction NLTxWM was non-significant. Higher WM and maths performance predicted larger benefits for WMT and NLT, respectively. Neuroimaging at baseline also contributed significant information about training gain. Different individuals showed as much as a three-fold difference in their responses to the same intervention. These results show that the impact of an intervention is highly dependent on individual characteristics of the child. If differences in responses could be used to optimize the intervention for each child, future interventions could be substantially more effective. Copyright © 2016 The Authors.

To evaluate the possible relationships between a health policy decision, in relation to the diabetes education strategies and the metabolic control outcomes. Longitudinal prospective cohort study. A random cohort sample of 276 type II diabetes mellitus subjects. All primary care centres in three regions of Catalonia. Patients were classified as specialised (n=59) or non-specialised (n=217) groups, as regards whether having received previous diabetes education before the start of the study. HbA1c values were evaluated in all subjects at baseline and after 5 years after receiving only conventional education. Baseline evaluation showed a better metabolic control in the specialised group (P=0.009). The final evaluation showed no significant differences in outcomes between the two groups (P=0.679). When baseline and outcomes values were compared, significant differences were observed in all subjects (P=0.001), the specialised group showed significantly poorer metabolic control (P<0.001), but in the group with previous conventional education no significant differences were observed (P=0.058). Our results suggest that the withdrawal of higher levels of diabetes education may play a major role in poor metabolic control, and that conventional diabetes education does not improve outcomes. Health policy in Primary Care should consider improving the level of diabetes education.

Concussion literature and treatment guidelines are inconclusive regarding the role of sex in symptom reporting at baseline and post-concussion. Although empirical evidence is lacking, it is generally regarded that females have a more severe symptomatic presentation than males at all time-points on the concussion spectrum. Our objective was to determine whether differences exist between males and females at baseline (pre-season/before concussion) or post-concussion for self-reported (1) prevalence of individual symptoms and (2) total symptom scores in high school and college athletes. Systematic review and meta-analysis of observational cohort studies; level of evidence, 1. A computerized search of the PubMed, SPORTDiscus, CINAHL, and Scopus databases was performed. Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines were followed. Criteria for inclusion were (1) self-report of symptoms at any time within the concussion spectrum, including baseline and after concussion, (2) study sample included high school and/or collegiate athletes aged 12-26 years, (3) concussions occurred during participation in sport, and (4) symptom reporting was separated by sex. The Quality Assessment Tool for Cohort Studies, Q-Coh, was utilized for quality assessment. Twenty-one studies met the criteria for inclusion: seventeen had good quality and four, acceptable quality. At baseline, females had significantly higher odds than males of reporting the individual symptoms of vision/hearing problems, headache/migraine, difficulty concentrating, energy/sleep disturbances, and emotional disturbances. Post-concussion, only one symptom demonstrated significant differences between males and females, with females demonstrating lower odds of reporting confusion than males. Statistically, at baseline and post-concussion, females had significantly higher total symptom scores on the Post-Concussion Scale (PCS) and the Sport Concussion Assessment Tool 2 (SCAT2), but when the standard mean difference was interpreted after back-transformation, these results were clinically insignificant. The symptomatic presentation of males and females, most notably the prevalence of specific symptoms, is very divergent. Females had higher total symptom scores at baseline and post-concussion, however, clinically this cannot be interpreted as a meaningful difference. It is possible that these differences can be explained by normal hormonal changes associated with the menstrual cycle. The implications of these findings are that symptomatic presentation during an individual female's menstrual cycle needs to be taken into consideration post-concussion when making return-to-play decisions, as returning to a completely asymptomatic level may not be a reasonable expectation.

Our primary aim was to determine the short-term effects of a ketogenic diet on cardiac ventricular function in patients with refractory epilepsy. Thirty-eight drug-resistant epileptic patients who were treated with a ketogenic diet were enrolled in this prospective study. Echocardiography was performed on all patients before beginning the ketogenic diet and after the sixth month of therapy. Two-dimensional, M-mode, color flow, spectral Doppler, and pulsed-wave tissue Doppler imaging measurements were performed on all patients. The median age of the 32 patients was 45.5 months, and 22 (57.8%) of them were male. Body weight, height, and body mass index increased significantly at the sixth month of therapy when compared with baseline values (P < 0.05). Baseline variables assessed by conventional M-mode echocardiography showed no significant difference at month 6 (P > 0.05). Doppler flow indices of mitral annulus and tricuspid annulus velocity of patients at baseline and month 6 showed no significant differences (P > 0.05). Tricuspid annular E/A ratio was lower at month 6 (P < 0.05). Although mitral annulus tissue Doppler imaging studies showed no significant difference (P > 0.05), there was a decrease in Ea velocity and Ea/Aa ratio gathered from tricuspid annulus at month 6 compared with baseline (P < 0.05). A 6-month duration ketogenic diet does not impair left ventricular functions in children with refractory epilepsy; however, it may be associated with a right ventricular diastolic dysfunction.

Background and objectives: While peritoneal dialysis with icodextrin is commonly used in patients with poor peritoneal membrane characteristics, the data on the usefulness of this solution in patients with lower transport characteristics are limited. The study was designed to compare icodextrin to glucose in Chinese prevalent peritoneal dialysis patients of different peritoneal transport characteristics (PET) categories. Design, setting, participants, & measurements: This was a randomized, double-blind, perspective control study. Stable prevalent continuous ambulatory peritoneal dialysis (CAPD) patients were randomized to either 7.5% icodextrin (ICO) or 2.5% glucose (GLU) solution for 4 wk. Peritoneal membrane function was measured to define PET category in baseline. Creatinine clearance (Ccr), urea nitrogen clearance (CBUN), ultrafiltration (UF) during the long night dwell, dialysate, and metabolic biomarkers were measured at baseline, 2, and 4 wk. UF, Ccr, and CBUN were compared among different PET categories. Results: A total of 201 CAPD patients were enrolled in the study. There were no baseline differences between the groups. Following 2 and 4 wk of therapy, Ccr, CBUN, and UF were all significantly higher in the ICO versus the GLU group. Additionally, switching to ICO resulted in a significant increase in UF in high, high-average, and low-average transporters as compared with baseline. The extent of increased UF was more obvious in higher transporters. Blood cholesterol level in the ICO group decreased significantly than that in the GLU group. Conclusion: Compared with glucose-based solution, 7.5% icodextrin significantly improved UF and small solute clearance, even in patients with low-average peritoneal transport. PMID:19808224

It is unclear if resistance training (RT) can be used to alter declines in autonomic modulation associated with aging. Young women (YW; range 18–25 yrs) and older women (OW; range 50–72 yrs) were compared at baseline. Only OW underwent supervised RT 2 days a week for 12-weeks. Baseline and post-training measurements included heart rate variability (HRV) and complexity (Sample Entropy) to assess autonomic modulation. The 12-weeks of RT consisted of 9 exercises performing 3 sets of 8–12 repetitions. At baseline, group differences in maximal strength, and autonomic modulation were evaluated with a one-way ANOVA with BMI as a covariate. In the OW, the effects of RT were evaluated with repeated-measures ANOVA in order to compare baseline to after RT. The YW had significantly (p≤0.05) lower diastolic, but not systolic blood pressure. The YW also had significantly (p≤0.05) greater absolute Ln (natural logarithm) high-frequency (HF) power and normalized HF power compared to the OW. In addition, there were significantly (p≤0.05) greater levels of normalized low-frequency power (LF) (and the LF/HF ratio) in the OW compared to the YW before RT. However, no difference was found for Sample Entropy. After RT, OW significantly (p≤0.05) increased the chest press (28%) and leg extension (33%). RT had no significant effect on any autonomic parameter suggesting that it may not be a sufficient stimulus to alter the effects of aging. PMID:28344732

To examine association of interactions between patient empowerment (PE) and health literacy with 1-year-later self-management behaviors in patients with type 2 diabetes (T2DM). A prospective design was employed in this study. Overall, 395 patients with T2DM completed self-reported questionnaires at baseline and 1year later. A hierarchical multiple regression was used to identify the association of interactions between PE and health literacy at baseline with the 1-year-later self-management behaviors. Interactions between PE and communicative and critical health literacy (CCHL) at baseline significantly associated with the 1-year-later global self-management behaviors in patients with T2DM. Among the participants who exhibited high PE at baseline, the scores of 1-year-later global self-management behaviors of the participants with a high CCHL at baseline were significantly higher than those with a low CCHL at baseline. Nevertheless, among the participants who exhibited low PE at baseline, no significant differences were identified in the 1-year-later global self-management behaviors between the participants with high vs. low CCHL at baseline. PE may improve self-management behaviors in patients with high CCHL, but may prove useless in patients with low CCHL. Healthcare providers should ensure that patients with T2DM have adequate CCHL prior to empowering them. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

To evaluate long-term, multiple risk factor intervention on physical, psychological and mental prognosis, and development of complications and cardiovascular disease in elderly type 2 diabetes patients. Our randomized, controlled, multicenter, prospective intervention trial included 1173 elderly type 2 diabetes patients who were enrolled from 39 Japanese institutions and randomized to an intensive or conservative treatment group. Glycemic control, dyslipidemia, hypertension, obesity, diabetic complications and atherosclerotic disease were measured annually. Instrumental activity of daily living, cognitive impairment, depressive symptoms and diabetes burden were assessed at baseline and 3 years. There was no significant difference in clinical or cognitive parameters at baseline between the two groups. The prevalence of low activities of daily living, depressive symptoms and cognitive impairment was 13%, 28% and 4%, respectively, and was similar in the two groups. A small, but significant difference in HbA1c between the two groups was observed at 1 year after the start of intervention (7.9% vs 8.1%, P < 0.05), although this significant difference was not observed after the second year. With the exception of coronary revascularization, there was no significant difference in fatal or non-fatal events between the two groups. Composite events were also similar in the two groups. This study showed no significant differences in fatal or non-fatal events between intensive and conventional treatment. The present study might clarify whether treatment of risk factors influences function and quality of life in elderly diabetic patients. © 2012 Japan Geriatrics Society.

A prospective, randomized, controlled study was performed to evaluate the effects of perioperative alanyl-glutamine-supplemented parenteral nutrition (PN) support on the immunologic function, intestinal permeability, and nutrition status of surgical patients with chronic radiation enteritis (CRE)-induced intestinal obstruction. Patients who received 0.4 g/kg/d alanyl-glutamine and isonitrogenous PN were assigned to an alanyl-glutamine-supplemented PN (Gln-PN) group and a control group, respectively. Serum levels of alanine aminotransferase and glutamine, body fat mass (FM), immunologic function, and intestinal permeability were measured before and after surgery. Serum glutamine levels of the Gln-PN group significantly exceeded that of the control group (P < .001; Gln-PN, baseline 460.7 ± 42.5 vs 523.3 ± 48.6 µmol/L on postoperative day 14 [POD14], P < .001; control, baseline 451.9 ± 44.0 vs 453.8 ± 42.3 µmol/L on POD14, P = .708). Lactulose/mannitol ratios of both groups decreased over time (Gln-PN, baseline 0.129 ± 0.0403 vs 0.024 ± 0.0107 on POD1 4; control, baseline 0.125 ± 0.0378 vs 0.044 ± 0.0126 on POD14, P < .001 in both groups). CD4/CD8-positive T-lymphocyte ratios significantly rose in both groups, with significant intergroup difference (P < .001; Gln-PN, baseline 1.36 ± 0.32 vs 1.82 ± 0.30 on POD14, P < .001; control, baseline 1.37 ± 0.25 vs 1.63 ± 0.31 on POD14, P < .001). In the Gln-PN group, FM increased from 3.68 ± 1.68 kg at baseline to 5.22 ± 1.42 kg on POD14 (P < .001). FM of control group increased from 3.84 ± 1.57 kg at baseline to 5.40 ± 1.54 kg on POD14 (P < .001). However, there were no significant intergroup differences (P = .614). Gln-PN significantly boosted the immune state and decreased the intestinal permeability of CRE patients. However, Gln-PN was not superior to standard PN in improving the nutrition state and intestinal motility of surgical patients with CRE-induced intestinal obstruction. © 2015 American Society for Parenteral and Enteral Nutrition.

This research investigated the effects of the transport of blood samples between centers/laboratories by car on coagulation tests. Five tubes of blood samples were taken from 20 healthy volunteers. The samples consisted of a baseline (control) group, centrifuged and noncentrifuged transported samples; centrifuged and noncentrifuged untransported samples. The groups of centrifuged and noncentrifuged samples were transported by car for 2 h. The centrifuged and noncentrifuged untransported samples were incubated in the laboratory until the transported samples arrived. Prothrombin time (PT) and activated partial thromboplastin time (APTT) tests were conducted for all samples. Significant differences between the baseline group and the centrifuged and noncentrifuged transported samples and the noncentrifuged untransported samples were found for APTT levels (p<0.05, for all). In addition, significant mean percentage differences in PT values were found between the baseline group and the noncentrifuged transported samples (p<0.001) and the noncentrifuged untransported samples (p=0.005). The mean level of PT in the noncentrifuged transported samples was outside the upper limit of the clinical decision level. Noncentrifuged transported samples showed clinically significant differences in PT test results that may have stemmed from mechanical agitation during transportation. Therefore, we recommend not transporting noncentrifuged specimens for PT testing by car.

Whether there are racial and ethnic disparities in the rate of cognitive decline among older adults is not clear. The purpose of this study was to determine if there are differences in cognitive decline among racial and ethnic older adults. Data were from the Health and Retirement Study, waves 1998-2010. Participants were community dwelling at baseline (n = 9,492), mostly female participants (58.8%), ranged in age from 65 to 105 years (M = 74.41, SD = 6.97), and had education levels that averaged less than high school (M = 11.7, SD = 3.4). Cognition was examined using a combined score from word recall, Serial 7's, backward counting, and naming tasks. To determine changes in cognition across 12 years, we utilized mixed effects models. Results indicated that after adjusting for covariates, race or ethnicity was unrelated to changes in cognitive performance, but there were significant differences in baseline cognition and these differences were more pronounced after adjusting for age, gender, education, poverty, heart disease, diabetes, high blood pressure. It is evident that there are significant differences in baseline cognition, although the rate of cognitive decline across 12 years did not vary significantly by race. These findings support previous assertions that the rate of cognitive decline is not associated with race and suggest that it is likely that baseline cognitive performance is a better indicator of performance over time. © The Author 2013.

National Collegiate Athletic Association (NCAA) concussion guidelines state that all NCAA athletes must have a concussion baseline test prior to commencing their competitive season. To date, little research has examined potential racial differences on baseline neurocognitive performance among NCAA athletes. The purpose of this study was to investigate differences between Black and White collegiate athletes on baseline neurocognitive performance and self-reported symptoms. A total of 597 collegiate athletes (400 White, 197 Black) participated in this study. Athletes self-reported their race on the demographic section of their pre-participation physical examination and were administered the Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) neurocognitive battery in a supervised, quiet room. Controlling for sex, data were analyzed using separate one-way analyses of covariance (ANCOVAs) on symptom score, verbal and visual memory, visual motor processing speed, and reaction time composite scores. Results revealed significant differences between White and Black athletes on baseline symptom score (F (1,542) = 5.82, p = .01), visual motor processing speed (F (1,542) = 14.89, p < .001), and reaction time (F (1,542) = 11.50, p < .01). White athletes performed better than Black athletes on baseline visual motor processing speed and reaction time. Black athletes reported higher baseline symptom scores compared to Whites. There was no statistical difference between race on verbal memory (p = .08) and that on visual memory (p = .06). Black athletes demonstrated disparities on some neurocognitive measures at baseline. These results suggest capturing an individual baseline on each athlete, as normative data comparisons may be inappropriate for athletes of a racial minority.

We conducted a prospective serial laboratory cohort study to assess the correlation of factor VIII (FVIII) levels in response to thrombolysis in patients with large vessel occlusion (LVO) and acute ischemic stroke (AIS). Patients with AIS with anterior circulation LVO were eligible for enrollment if treated within 4.5 hours from last seen normal with intravenous tissue plasminogen activator (tPA). Patients (n = 29) had a mean age of 71 years and median National Institute of Health Stroke Scale of 14. Baseline pre-tPA FVIII was not significantly correlated with clot burden score (-0.147, P = .447) or vessel recanalization (-0.133, P = .499). Median FVIII decreased significantly from baseline to 6 hours post-tPA (282% to 161%, P = .002), but delta in FVIII level did not correlate with vessel recanalization (0.013, P = .948). There was no difference between median FVIII level at baseline and 90 days post-AIS. FVIII level decreased significantly after tPA, but baseline FVIII level and early change in FVIII level were not significant predictors of clot burden, vessel recanalization after thrombolysis, or symptomatic hemorrhage.

This study prospectively examined the course of depression in African American and Caucasian midlife women over an 11-year period. Racial differences in lifetime history of depression, severity of depressive symptoms and rates of depressive disorders at baseline, and persistence or recurrence of depression over an 11 year period were examined. Predictors of persistence/recurrence of depression were also examined. The sample was comprised of 423 midlife women enrolled in the Study of Women Across the Nation (SWAN) Mental Health Study (MHS). All participants completed baseline and annual assessments, which included self-reported measures of health, functioning, and psychosocial factors, and clinician administered assessments of psychiatric disorders. Logistic regression analyses were used to examine predictors of depression persistence/recurrence. Findings indicated that African American and Caucasian women did not differ significantly in rates of lifetime and baseline depressive disorders, or severity of depressive symptoms. Annual assessments revealed no significant differences between the groups in rates of persistent/recurrent depression. While African American and Caucasian women do not differ in recurrence of depression at midlife, factors associated with depression differed by race.

We performed a meta-analysis of three sub-studies of the randomized Tamoxifen Exemestane Adjuvant Multinational (TEAM) trial to determine the effects of exemestane and tamoxifen on bone health. Patients received exemestane or tamoxifen as adjuvant therapy for hormone receptor-positive breast cancer. Bone mineral density (BMD) was assessed at baseline and after 12 and 24 months of treatment. Bone turnover markers were also measured. Patients receiving tamoxifen showed a mean increase from baseline in lumbar spine BMD of 1.2% at month 12 and 0.2% at month 24. Patients receiving exemestane showed a mean decrease from baseline of 2.6% after 12 months and 3.5% after 24 months. There were significant differences in the changes in lumbar spine BMD between treatment groups (P < 0.0001 at both time points). Changes in BMD from baseline at the total hip were also significantly different between exemestane and tamoxifen (P < 0.05 at both time points). Bone turnover markers decreased from baseline with tamoxifen and increased with exemestane. Exemestane resulted in decreases in BMD and increases in bone turnover markers. BMD increased and bone turnover markers decreased with tamoxifen.

To investigate the effects of health education based on integrative therapy of Chinese and Western medicine for type 2 diabetes mellitus (T2DM) from the aspects of knowledge, attitude and practice (KAP), health-related quality of life (HRQoL), body mass index (BMI) and glucose control. Patients were individually randomized into intervention group (receiving integrative education, n=120) and control group (receiving usual education, n=120). The primary outcome was the changes in glycosylated hemoglobin A1c (HbA1c) levels after 3, 6, 9 and 12 months from baseline. Hierarchical linear models (HLMs) were used to assess within-group changes in outcomes over time and between-group differences in patterns of change. Secondary outcomes were KAP scores, HRQoL scores and BMI after 6 and 12 months, paired-sample t test was used to assess within-group changes in outcomes in 6 and 12 months, independent-sample t test was used to assess between-group differences in patterns of change. HbA1c decreased statistically from baseline to 3 months, from 3 to 6 months, from 6 to 9 months and from 9 to 12 months in the intervention group (all P<0.01); and decreased significantly from baseline to 3 months, and from 3 to 6 months in the control group P<0.01). There was a significant between-group difference from baseline to 3 months (P=0.044), from 6 to 9 months (P<0.01) and from 9 to 12 months (P<0.01). Significant improvements in the intervention group along with significant between-group differences were found in KAP and HRQoL scores respectively (all P<0.05). The number in the intervention group of normal weight increased from 56 at baseline to 81 (6 months), 94 (12 months), the number in the control group were 63 (baseline), 69 (6 months), 70 (12 months), the χ 2 of hierarchical analysis of BMI were 6.93 (P=0.075), 10.31 (P=0.016), 15.53 (P<0.01), respectively. Health education based on integrative therapy of Chinese and Western medicine is beneficial to the control of T2DM and should be recommended for T2DM.

This study assessed the efficacy of oral care education among nursing home staff members to improve the oral health of residents. Nursing home support staff members (NHSSMs) in the study group received oral care education at baseline between a pretest and posttest. NHSSMs' oral care knowledge was measured using a 20-item knowledge test at baseline, posteducation, and at a 6-month follow-up. Residents' oral health was assessed at baseline and again at a 6-month follow-up using the Modified Plaque Index (PI) and Modified Gingival Index (GI). Among staff members who received the oral care education (n = 32), posttest knowledge statistically significantly increased from the pretest level (p < .05). Thirty-nine control residents of the nursing homes and 41 study residents participated. Among residents in the study group, PI decreased at 6 months compared to baseline (p < .05), but there was no statistically significant difference in their GI measurements between baseline and 6-month follow-up (p= .07). © 2012 Special Care Dentistry Association and Wiley Periodicals, Inc.

The effect of Stroop test (ST)-induced stress on autonomic nervous system activity is often examined via measurement of heart rate variability (HRV). However, HRV may be significantly affected by interfering factors, including vocalization and inappropriate body position. Surprisingly, published studies ignore these issues, so the aim of our study was to test the innovative procedure for correct HRV measurement in individuals exposed to ST. Moreover, we examined possible gender differences in HRV and heart rate (HR) during ST. Healthy participants (21 men, 34 women) were placed in a supine position (no orthostatic activation) and then exposed to a 5 min relaxation period and a 5 min period of computerized ST (no vocalization). We found significant differences in HR and HRV parameters in both genders during ST when compared to relaxation (baseline) values. On the other hand, there were no significant differences in HR and HRV between males and females (except for a higher baseline HR in women). Also, reactivity to ST stress (difference between baseline and ST value) showed no gender differences. In conclusion, when performed in a supine position and without vocalization, the ST induces significant stress-related changes of HR and HRV in both genders, with no gender differences in the magnitude of reaction to ST stress. This experimental procedure can be used for correct examination of mental stress-related changes in the autonomic nervous system, and is particularly useful for examining mixed-gender experimental groups.

2016-06-01
Sex differences in weight loss are often seen despite using the same weight loss program. There has been relatively little investigation of physiological influences on weight loss success in males and females, such as energy homeostasis and appetite regulating hormones. The aims were to 1) characterise baseline plasma leptin, ghrelin and adiponectin concentrations in overweight and obese males and females, and 2) determine whether baseline concentrations of these hormones predict weight loss in males and females. Subjects were overweight or obese (BMI 25-40 kg/m(2)) adults aged 18-60 years. Weight was measured at baseline, and after three and six months participation in a weight loss program. Baseline concentrations of leptin, adiponectin and ghrelin were determined by enzyme-linked immunosorbent assay (ELISA). An independent t-test or non-parametric equivalent was used to determine any differences between sex. Linear regression determined whether baseline hormone concentrations were predictors of six-month weight change. Females had significantly higher baseline concentrations of leptin, adiponectin and unacylated ghrelin as well as ratios of leptin:adiponectin and leptin:ghrelin. The ratio of acylated:unacylated ghrelin was significantly higher in males. In males and females, a higher baseline concentration of unacylated ghrelin predicted greater weight loss at six months. Additionally in females, higher baseline total ghrelin predicted greater weight loss and a higher ratio of leptin:ghrelin predicted weight gain at six months. A higher pre-weight-loss plasma concentration of unacylated ghrelin is a modest predictor of weight loss success in males and females, while a higher leptin:ghrelin ratio is a predictor of weight loss failure in females. Further investigation is required into what combinations and concentrations of these hormones are optimal for weight loss success. Copyright © 2016 Elsevier Ltd. All rights reserved.

Abstract Background: Multiple abnormal metabolic traits are found together or “cluster” within individuals more often than is predicted by chance. The individual and combined role of adiposity and insulin resistance (IR) on metabolic trait clustering is uncertain. We tested the hypothesis that change in trait clustering is a function of both baseline level and change in these measures. Methods: In 2616 nondiabetic Framingham Offspring Study participants, body mass index (BMI) and fasting insulin were related to a within-person 7-year change in a trait score of 0–4 Adult Treatment Panel III metabolic syndrome traits (hypertension, high triglycerides, low high-density lipoprotein cholesterol, hyperglycemia). Results: At baseline assessment, mean trait score was 1.4 traits, and 7-year mean (SEM) change in trait score was +0.25 (0.02) traits, P<0.0001. In models with BMI predictors only, for every quintile difference in baseline BMI, the 7-year trait score increase was 0.14 traits, and for every quintile increase in BMI during 7-year follow-up, the trait score increased by 0.3 traits. Baseline level and change in fasting insulin were similarly related to trait score change. In models adjusted for age–sex–baseline cluster score, 7-year change in trait score was significantly related to both a 1-quintile difference in baseline BMI (0.07 traits) and fasting insulin (0.18 traits), and to both a 1-quintile 7-year increase in BMI (0.21 traits) and fasting insulin (0.18 traits). Conclusions: Change in metabolic trait clustering was significantly associated with baseline levels and changes in both BMI and fasting insulin, highlighting the importance of both obesity and IR in the clustering of metabolic traits.

There is a need to find very early markers for pre-clinical Alzheimer's disease as interventions early in the disease process are thought to be most effective. The present study aimed to address the potential relation between cerebrospinal fluid (CSF) biomarkers and reduced cognitive function in a relatively young cohort of memory clinic patients with subjective cognitive decline. 122 patients (mean age 63 years) with subjective cognitive decline were recruited from two university memory clinics and followed for two years. The main finding was that the subgroup with objective memory decline during the study period had significantly higher T-tau at baseline than the group with improved memory. Baseline CSF variables showed a trend toward more pathological values in the patients with memory decline compared to those who improved or remained stable. The baseline memory score of those who declined was significantly better than the baseline score of those who improved over two years. The general trend for the whole group was improved memory and executive test scores. There were no differences in cognitive scores based on CSF quartiles at baseline, nor were there differences in cognitive outcome for patients with early amnestic mild cognitive impairment versus average cognitive function at baseline. The main finding that T-tau rather than amyloid-β was associated with memory decline do not support the prevailing opinion about the chain of events assumed to take place in Alzheimer's disease. In addition, memory decline was not associated with poor baseline memory score. Thus, a memory cut-off indicating low baseline memory would not would have identified the declining group.

Objective. To investigate the relationship between binge eating behavior and weight loss maintenance over a two-year period in adults. Design. Secondary data analysis using the Keep It Off study, a randomized trial evaluating an intervention to promote weight loss maintenance. Participants. 419 men and women (ages: 20 to 70 y; BMI: 20–44 kg/m2) who had intentionally lost ≥10% of their weight during the previous year. Measurements. Body weight was measured and binge eating behavior over the past 6 months was reported at baseline, 12 months and 24 months. Height was measured at baseline. Results. Prevalence of binge eating at baseline was 19.4% (n = 76). Prevalence of binge eating at any time point was 30.1% (n = 126). Although rate of weight regain did not differ significantly between those who did or did not report binge eating at baseline, binge eating behavior across the study period (additive value of presence or absence at each time point) was significantly associated with different rates of weight regain. Conclusion. Tailoring weight loss maintenance interventions to address binge eating behavior is warranted given the prevalence and the different rates of weight regain experienced by those reporting this behavior.

Despite new improvements on cardiopulmonary resuscitation (CPR), brain damage is very often after resuscitation. To assess the prognostic value of cerebral oxygen saturation measurement (rSO 2 ) for assessing prognosis on patients after cardiopulmonary resuscitation. Retrospective analysis. We analyzed 25 post-CPR patients (12 female and 13 male). All the patients were cooled to a target temperature of 33-34°C. The Glascow Coma Scale (GCS), Corneal Reflexes (CR), Pupillary Reflexes (PR), arterial Base Excess (BE) and rSO 2 measurements were taken on admission. The rewarming GCS, CR, PR, BE and rSO 2 measurements were made after the patient's temperature reached 36°C. In survivors, the baseline rSO 2 value was 67.5 (46-70) and the percent difference between baseline and rewarming rSO 2 value was 0.03 (0.014-0.435). In non-survivors, the baseline rSO 2 value was 30 (25-65) and the percent difference between baseline and rewarming rSO 2 value was 0.031 (-0.08 to -20). No statistical difference was detected on percent changes between baseline and rewarming values of rSO 2. Statistically significant difference was detected between baseline and rewarming GCS groups (p=0.004). No statistical difference was detected between GCS, CR, PR, BE and rSO 2 to determine the prognosis. Despite higher values of rSO 2 on survivors than non-survivors, we found no statistically considerable difference between groups on baseline and the rewarming rSO 2 values. Since the measurement is simple, and not affected by hypotension and hypothermia, the rSO 2 may be a useful predictor for determining the prognosis after CPR.

Several studies have examined changes in patient-reported outcome measures (PROMs) after anterior cruciate ligament (ACL) injury, but no studies to date have prospectively evaluated changes from preinjury baseline through injury and follow-up among ACL-injured patients compared to the baseline and follow-up changes of uninjured patients. To examine changes in PROMs over time from preinjury baseline to at least 2 years after ACL reconstruction and to compare these changes with those of an uninjured control group having similar physical activity requirements. Cohort study; Level of evidence, 2. The authors conducted a prospective cohort study with a nested case-control analysis at a US service academy. All incoming first year students were recruited to participate in this study. Consenting participants completed a baseline questionnaire that included the KOOS (Knee injury and Osteoarthritis Outcome Score), WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index), and MARS (Marx Activity Rating Scale). Participants who sustained a subsequent ACL injury completed assessments at the time of surgery and at 6, 12, and 24 months after surgery. Healthy participants were recruited to repeat the baseline assessments within 1 year of graduation. Inter- and intragroup differences at these time points were evaluated with dependent and independent t tests, respectively. We also compared these results with established minimum clinically important difference (MCID) values. Of 1268 first year students entering the academy, 1005 with no previous injuries consented to participate in this study (82% male, mean ± SD age 19 ± 1 years). Of those enrolled, 30 suffered an ACL injury and met the inclusion criteria for this study. Ninety uninjured control students who met the inclusion criteria completed follow-up assessments. There were statistically significant differences across all KOOS and WOMAC subscales between ACL-injured group and uninjured group at the time of the final follow-up assessment. Four KOOS subscales (Pain, Symptoms, Sports and Recreation Function, and Knee-Related Quality of Life) and the WOMAC Stiffness subscale demonstrated >8-point differences between groups, which exceeded the established MCID for these instruments. There were no significant differences between the ACL-injured group and uninjured groups noted for the MARS ( P = .635). At the time of final follow-up, the ACL-injured group also reported significant deficits on the WOMAC Stiffness subscale ( P = .032), the MARS ( P = .030), and all KOOS subscales, with the exception of Functional Activities of Daily Living, as compared with their preinjury baseline scores. These deficits exceeded the established MCID values for 3 KOOS subscales and the MARS. Patients with ACL injuries reported significant deficits on PROMs at least 2 years after surgical reconstruction in relation to preinjury baseline scores and an uninjured control group. Many of these deficits exceeded established MCID values.

Objective Obstructive sleep apnoea (OSA) is strongly associated with cardiovascular disease. However, acute cardiovascular effects of repetitive airway obstruction are poorly understood. While past research used a sustained Mueller manoeuver to simulate OSA we employed a series of gasping efforts to better simulate true obstructive apnoeas. This report describes acute changes in cardiac anatomy and flow related to sudden changes in intrathoracic pressure. Methods and results 26 healthy, normal weight participants performed 5–6 gasping efforts (target intrathoracic pressure −40 mm Hg) while undergoing Doppler echocardiography. 14 participants had sufficient echocardiographic images to allow comparison of atrial areas during the manoeuver with baseline measurements. Mitral and tricuspid E-wave and A-wave velocities postmanoeuver were compared with baseline in all participants. Average atrial areas changed little during the manoeuver, but variance in both atrial areas was significantly greater than baseline. Further, an inverse relationship was noted with left atrial collapse and right atrial enlargement at onset of inspiratory effort. Significant inverse changes were noted in Doppler flow when comparing the first beat postmanoeuver (pMM1) with baseline. Mitral E-wave velocity increased 9.1 cm/s while tricuspid E-wave velocity decreased 7.0 cm/s; by the eighth beat postmanoeuver (pMM8) values were not different from baseline. Mitral and tricuspid A-wave velocities were not different from baseline at pMM1, but both were significantly higher by pMM8. Conclusions Repetitive obstructive apnoeas produce dynamic, inverse changes in atrial size and Doppler flow across the atrioventricular valves. These observations have important implications for understanding the pathophysiology of OSA. PMID:27127636

Although the neurophysiology underlying pharmacotherapy for bipolar disorder remains poorly understood, recent studies suggest that therapeutic mechanisms may be reflected in changes in concentrations of N-acetylaspartate (NAA), a putative measure of neuronal integrity and metabolism. In this study, we used magnetic resonance spectroscopy (MRS) to examine prefrontal NAA in patients receiving quetiapine for bipolar mania. On the basis of previous findings, we hypothesized that remission would be associated with increased NAA concentrations in the prefrontal cortex. Thirty-one manic bipolar patients and 13 healthy subjects were recruited to participate in this prospective study. All subjects participated in MRS at baseline and after 8 weeks of treatment. Bipolar subjects received open-label quetiapine monotherapy (mean dose [SD], 584 [191] mg). Fourteen patients remitted (Young Mania Rating Scale ≤ 12) ("remitters"), 11 patients did not ("nonremitters"), and 6 patients were lost to follow-up. Bipolar and healthy subjects did not significantly differ in baseline NAA or degree of change during the 8 weeks. Remitters showed greater mean baseline NAA concentrations in the right ventrolateral prefrontal cortex compared with nonremitters (P < 0.05). In the anterior cingulate, remitters showed near significantly decreased baseline NAA concentrations at baseline (P < 0.06), and significant differences in NAA change during the 8 weeks of treatment (P < 0.03). Manic patients who remitted with quetiapine treatment in the course of this study exhibited distinct patterns of baseline prefrontal NAA concentration, coupled with decreased NAA in the anterior cingulate with treatment; the latter possibly reflecting disparate effects of quetiapine on neuronal metabolism. These data support suggestions that therapeutic effects of quetiapine involve metabolic effects on specific prefrontal regions.

Using a novel digital meniscometer (PDM), alterations in tear meniscus radius (TMR) were measured simultaneously with blink rate (BR) following the instillation of artificial tears. Central TMR and BR of 22 subjects (11 male and 11 female; mean age, 24.3 ± 2.6 SD years) were measured at baseline, and 0, 1, 5, 10, and 30 minutes after instillation of an artificial tear containing hydroxypropyl-guar and glycol (SYS) or saline (SAL). A dose of 35 μL was applied in one eye in a randomized order with a washout period between each drop. For SAL, compared to baseline TMR (0.33 ± 0.08 mm), TMR significantly increased with drop instillation (1.55 ± 0.69 mm) and at 1 minute (0.66 ± 0.36 mm; P < 0.05), but returned to baseline after 5 minutes. For SYS, TMR (0.32 ± 0.07 mm) remained significantly increased after application (1.62 ± 0.81 mm), and at 1 minute (0.81 ± 0.43 mm) and 5 minutes (0.39 ± 0.08 mm; P < 0.05). Compared to baseline BR with SAL (14.8 ± 7.7) and SYS (14.9 ± 9.4), values were significantly increased upon drop instillation (22.5 ± 11.8; 21.3 ± 11.8; P < 0.05), but returned to baseline after 1 minute. Dry eye symptoms were correlated with baseline BR (r = 0.550, P = 0.008). Results indicate that PDM can detect changes in TMR following instillation of artificial tears. Difference in residence time reflects the different viscosity of each drop. An overload with a large drop may result in an initially increased BR.

Humans in Antarctica face different environmental challenges, such as low ultra-violet radiation, which is crucial for vitamin D production in humans. Therefore we assessed changes in 25-OH-vitamin D serum concentration during 13 months of overwintering at the German Stations Neumayer II and III (2007-2012). We hypothesized that (i) 25-OH-vitamin D serum concentration would significantly decrease, (ii) changes would be affected by age, gender, baseline (i.e. pre-overwintering) fat mass, baseline 25-OH-vitamin D serum concentration, and station residence, and (iii) our results would not differ from similar previous studies in comparable high latitudes. 25-OH-vitamin D serum concentrations were determined before, after, and monthly during the campaigns from venous blood samples of n = 43 participants (28 men, 15 women). Baseline fat mass was determined via bio impedance analysis and body plethysmography. Data were analyzed for change over time, dependency on independent parameters, and after categorization for sufficiency (>50nmol/l), insufficiency (25-50nmol/l), and deficiency (<25nmol/l). Results were compared with data from similar previous studies. We found a significant decrease of 25-OH-vitamin D with dependency on month. Age, gender, fat mass, and station residence had no influence. Only baseline 25-OH-vitamin D serum concentrations significantly affected subsequent 25-OH-vitamin D values. Overwinterings at the Antarctic German research stations Neumayer II and III are associated with a decrease in 25-OH-vitamin D serum concentrations, unaffected by age, gender, baseline fat mass, and station residence. Higher baseline vitamin D serum concentrations might protect from subsequent deficiencies. Residence at the Neumayer Stations may lead to lower vitamin D serum concentrations than found in other comparable high latitudes.

To quantify median nerve characteristics before and after strenuous wheelchair propulsion and relate them to symptoms of carpal tunnel syndrome (CTS). We hypothesized that persons with and without symptoms of CTS would have significantly different nerve characteristics at baseline and after propulsion. A repeated-measures design was used to obtain ultrasound images of the median nerve at 3 levels of the wrist (radius, pisiform, and hamate) before and after wheelchair propulsion. Investigators were blinded to subject history related to CTS. The 2007 and 2008 National Veterans Wheelchair Games and the Human Engineering Research Laboratories. Fifty-four participants between the ages of 18 and 65 years with a nonprogressive disability who used a manual wheelchair as their primary means of mobility completed this study. Participants completed questionnaires regarding demographics and the presence and severity of symptoms of CTS. Ultrasound images of the median nerve were obtained before and after a 15-minute strenuous wheelchair-propulsion task. Baseline values and post-propulsion changes were determined for median nerve cross-sectional area, flattening ratio, and swelling ratio. Differences in median nerve variables between symptomatic and asymptomatic groups were assessed. No significant differences between symptom groups were identified at baseline; however, persons with symptoms of CTS showed a significantly different percent change from baseline compared with the asymptomatic participants for cross-sectional area at pisiform (P = .014) and flattening ratio at hamate (P = .022), and they showed a strong trend toward a difference in swelling ratio (P = .0502). For each of these variables, the change in the symptomatic group was in the opposite direction of the change in the asymptomatic group. We found several median nerve responses to wheelchair propulsion associated with symptoms of CTS. These responses occurred even though no baseline ultrasound difference was found based on symptoms. Future research is necessary to determine how propulsion characteristics (ie, force, repetition, and posture) affect the median nerve response.

Idiopathic pulmonary fibrosis (IPF) is a chronic, devastating, lung disease, with few therapeutic options. Data are limited with respect to the long-term effect of exercise training (ET) in IPF. This study sought to evaluate the long-term effects of a 12-week ET program on clinical outcomes in IPF patients. Thirty-four IPF patients were randomly allocated to ET or control groups. ET group participated in a 12-week supervised exercise program, while the control group continued with regular medical treatment alone. Exercise capacity, 30 s-chair-stand test for leg strength, dyspnea, and Saint George's Respiratory Questionnaire (SGRQ) for quality of life (QOL) were assessed at baseline and re-evaluated at 11 months from baseline. In addition, at 30-month time point from baseline, the impact of the 12-week intervention was analyzed with respect to survival and cardio-respiratory-related hospitalizations. Thirty-two patients completed the 12-week intervention and 28 patients (14 in each group) were re-evaluated. At 11-month follow-up, no significant differences between the groups and time effect were demonstrated for most outcomes. ET group showed preserved values at the baseline level while the control group showed a trend of deterioration. Only the 30 s-chair-stand test (mean difference 3 stands, p = 0.01) and SGRQ (mean difference -6 units, p = 0.037) were significantly different between the groups. At 30 months, the survival analysis showed three deaths, eight hospitalizations occurred in the control group versus one death, one lung transplantation and seven hospitalizations in the ET group, with no significant differences between groups. At 11-month follow-up, the 12-week ET program showed clinical outcomes were preserved at baseline levels with some maintenance of improvements in leg strength and QOL in the ET group. The control group showed a trend of deterioration in the outcomes. At 30 months, the 12-week ET program did not show benefits in prognosis although the study was underpowered to detect such differences. We suggest including ET as a long-term continued treatment and as a core component of pulmonary rehabilitation programs for IPF patients.

Neuromuscular blocking drugs have been implicated in intraoperative bronchoconstrictive episodes. We examined the effects of clinically relevant doses of cisatracurium and rocuronium on the lung mechanics of pediatric subjects. We hypothesized that cisatracurium and rocuronium would have bronchoconstrictive effects. We studied ASA physical status I and II pediatric subjects having elective dental or urological procedures, requiring general anesthesia with endotracheal intubations with either cisatracurium or rocuronium. Pulmonary function tests were performed before and after neuromuscular blocking drug dosing and again after albuterol administration. Using forced deflation and passive deflation techniques, forced vital capacity (FVC) and maximum expiratory flow rate at 10% (MEF10) of FVC were obtained. Fractional changes from the baseline were used to compare subjects. Changes in MEF10 of >30% were considered clinically significant. A Shapiro-Wilk test, paired t test, and Wilcoxon rank sum test were used to analyze the data. Twenty-five subjects (median age = 5.25 years; range = 9 months-9.9 years) were studied; 12 subjects received cisatracurium and 13 subjects received rocuronium. Data are shown as mean proportional change ± SD or, in the case of not normally distributed, median proportional change (first, third quartile) with P values. In the cisatracurium group, there were no differences between baseline and postneuromuscular blocker administration in the fractional change from the baselines of FVC (1.00 ± 0.04, P = 0.5), but there was a significant decrease in MEF10 (0.80 ± 0.18, P = 0.002). In the rocuronium group, there were small yet significant decreases of FVC (0.99 [first quartile 0.97, third quartile 1], P = 0.02) and significant decreases in MEF10 (0.78 ± 0.26, P = 0.008). After administration of albuterol in the cisatracurium group, FVC increased slightly but significantly from baseline values (1.02 ± 0.02, P = 0.005). MEF10 increased significantly beyond baseline values (1.24 ± 0.43, P =0.04). In the rocuronium group, there were also significant differences between baseline and postalbuterol administration from the baseline value of FVC (1.02 ± 0.02, P = 0.004) and MEF10 (1.23 ± 0.29, P = 0.01). At clinically relevant doses, both cisatracurium and rocuronium caused changes in lung function, indicating constriction of smaller airways. In general, these changes were mild and not clinically detectable. However, in the rocuronium group, 3 of 13 patients showed more noticeable decreases in MEF10 (≤50%), demonstrating the potential for significant broncho-bronchiolar constriction in susceptible patients.

Improving outcomes and health resource use for patients with chronic obstructive pulmonary disease (COPD) care is a priority for health systems. The Health Buddy Program, a content-driven telehealth system coupled with care management, is designed to enhance patient education, self-management, and timely access to care. To examine the effects of the Health Buddy Program on resource use among Medicare patients with COPD who participated in a Centers for Medicare and Medicaid Services demonstration project from 2006 to 2010. Medicare fee-for-service beneficiaries with COPD who enrolled in the intervention at two participating clinics were propensity-score matched to similar patients with COPD identified from a 5% random sample of Medicare patients. Difference-in-difference analyses descriptively compared the program's effect on quarterly healthcare resource use over the 3-year study period compared with baseline. Negative binomial models estimated the association of the program with healthcare resource outcomes adjusting for significant (P<0.05) baseline differences post matching. The effect of the Health Buddy Program on quarterly all-cause and respiratory-related hospital admissions, hospital admissions for COPD exacerbations, and all-cause emergency department use was assessed after matching. Intervention (n=619) and matched control subjects (n=619) had similar baseline characteristics after matching. The Health Buddy Program was associated with 23% lower quarterly all-cause hospital admissions and 40% lower quarterly respiratory-related hospital admissions compared with baseline for intervention beneficiaries versus control subjects. In subgroup analyses, patients who engaged in the intervention during the study period (n=247) demonstrated significantly lower quarterly hospital admissions for COPD exacerbations. The Health Buddy Program was not associated with reductions in quarterly emergency department use. Results were robust in analyses that adjusted for significant differences in baseline characteristics after matching. A content-driven telehealth system combined with care management has the potential to improve health outcomes in Medicare beneficiaries with COPD.

We revisit correlations of neutrino oscillation parameters in reactor and long-baseline neutrino oscillation experiments. A framework based on an effective value of θ13 is presented, which can be used to analytically study the correlations and explain some questions including why and when δC P has the best fit value of -π /2 , why current and future long-baseline experiments will have less precision of δC P around ±π /2 than that around zero, etc. Recent hints on the C P phase are then considered from the point of view that different reactor and long-baseline neutrino experiments provide currently different best-fit values of θ13 and θ23. We point out that the significance of the hints changes for the different available best-fit values.

With institutional review board approval, 33 patients who needed restoration of noncarious cervical lesions (NCCL) were enrolled in this study. A total of 92 NCCL were selected and randomly assigned to three groups: (1) Ambar (FGM), a two-step etch-and-rinse adhesive (control), combined with the nanofilled composite resin Filtek Supreme Plus (FSP; 3M ESPE); (2) Fuji II LC (GC America), a traditional resin-modified glass ionomer (RMGIC) restorative material; (3) Ketac Nano (3M ESPE), a nanofilled RMGIC restorative material. Restorations were evaluated at six months and one year using modified United States Public Health Service parameters. At six months after initial placement, 84 restorations (a 91.3% recall rate) were evaluated. At one year, 78 restorations (a 84.8% recall rate) were available for evaluation. The six month and one year overall retention rates were 93.1% and 92.6%, respectively, for Ambar/FSP; 100% and 100%, respectively, for Fuji II LC; and 100% and 100%, respectively, for Ketac Nano with no statistical difference between any pair of groups at each recall. Sensitivity to air decreased for all three adhesive materials from the preoperative to the postoperative stage, but the difference was not statistically significant. For Ambar/FSP, there were no statistical differences for any of the parameters from baseline to six months and from baseline to one year. For Fuji II LC, surface texture worsened significantly from baseline to six months and from baseline to one year. For Ketac Nano, enamel marginal staining increased significantly from baseline to one year and from six months to one year. Marginal adaptation was statistically worse at one year compared with baseline only for Ketac Nano. When parameters were compared for materials at each recall, Ketac Nano resulted in significantly worse color match than any of the other two materials at any evaluation period. At one year, Ketac Nano resulted in significantly worse marginal adaptation than the other two materials and worse marginal staining than Fuji II LC. Surface texture was statistically worse for Fuji II LC compared with the other two materials at all evaluation periods. The one-year retention rate was statistically similar for the three adhesive materials. Nevertheless, enamel marginal deficiencies and color mismatch were more prevalent for Ketac Nano. Surface texture of Fuji II LC restorations deteriorated quickly.

To estimate the yearly rate of change of best-corrected visual acuity (BCVA) and the risk of loss 1 line or more over 1 year and to identify risk factors for BCVA loss in patients with Stargardt disease (STGD1). Multicenter, prospective cohort study. Two hundred fifty-nine patients (489 eyes) with molecularly confirmed STGD1 enrolled at 9 centers in the United States and Europe. Participants were followed up every 6 months, and data at the baseline and 6- and 12-month visits were analyzed. Best-corrected visual acuity was measured using the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol. Standardized reporting forms were used to collect participants' characteristics and clinical observations. Linear mixed effects models were used to estimate the rate of BCVA loss. Linear models with generalized estimating equations were used to identify risk factors for BCVA loss of 1 line or more over 1 year. Change in BCVA over 1 year. Cross-sectional analysis at baseline showed that earlier symptom onset and longer duration since onset was associated with worse BCVA. Longitudinal analysis showed no overall significant change of BCVA within 12 months, but the rate of BCVA change was significantly different by baseline BCVA (P < 0.001). The BCVA of eyes with baseline BCVA of 20/25 or better declined at a rate of 2.8 ETDRS letters per year (P = 0.10), eyes with baseline BCVA between 20/25 and 20/70 declined at a rate of 2.3 ETDRS letters per year (P = 0.002), eyes with baseline BCVA between 20/70 and 20/200 declined at a rate of 0.8 ETDRS letters per year (P = 0.08), and eyes with baseline BCVA worse than 20/200 showed a significant improvement of 2.3 ETDRS letters per year (P < 0.001). Overall, 12.9% of eyes lost 1 line or more, and the risk of such BCVA loss was different by baseline BCVA level (P = 0.016). Smoking and vitamin A use was not associated significantly with baseline BCVA, nor with rate of BCVA loss over 1 year. Change in BCVA in STGD1 patients over a 12-month period was small, but varied depending on baseline BCVA. Given the slow change during 1 year, BCVA is unlikely to be a sensitive outcome measure for STGD1 treatment trials with 1 year's duration. Copyright © 2017 American Academy of Ophthalmology.

To examine how corneal astigmatism changes with age over 20 years after cataract surgery and to assess whether the changes differ from those in eyes that did not have surgery. Hayashi Eye Hospital, Fukuoka, Japan. Retrospective case study. Using an autokeratometer, corneal astigmatism was measured preoperatively, at baseline (the day the surgically induced astigmatism stabilized), and 10 years and 20 years after baseline. The change in corneal astigmatism between baseline and 10 years, 10 years and 20 years, and baseline and 20 years was determined using power vector analysis and compared between the time intervals and between groups. The study assessed 74 eyes that had phacoemulsification with a horizontal scleral incision more than 21 years ago (surgery group) and 68 eyes that did not have surgery (no-surgery group). The mean vertical/horizontal change in corneal astigmatism (J0) between baseline and 20 years was -0.64 diopter (D) in the surgery group and -0.49 D in the no-surgery group. The oblique change (J45) was -0.03 D in the surgery group and 0.07 D in the no-surgery group. Using multivariate comparison, the mean J0 and J45 values were not significantly different between baseline and 10 years or between 10 years and 20 years in both groups (P ≥ .2350). The J0 and J45 values were not significantly different between the 2 groups at any time interval (P ≥ .1331). Corneal astigmatism continues to change toward against-the-rule astigmatism over 20 years after cataract surgery. This change was similar in eyes that did not have surgery.

Differences in results of baseline and subsequent annual repeat rounds provide important information for optimising the regimen of screening. A prospective cohort study of 65,374 was reviewed to examine the frequency/percentages of the largest noncalcified nodule (NCN), lung cancer cell types and Kaplan-Meier (K-M) survival rates, separately for baseline and annual rounds. Of 65,374 baseline screenings, NCNs were identified in 28,279 (43.3%); lung cancer in 737 (1.1%). Of 74,482 annual repeat screenings, new NCNs were identified in 4959 (7%); lung cancer in 179 (0.24%). Only adenocarcinoma was diagnosed in subsolid NCNs. Percentages of lung cancers by cell type were significantly different (p < 0.0001) in the baseline round compared with annual rounds, reflecting length bias, as were the ratios, reflecting lead times. Long-term K-M survival rate was 100% for typical carcinoids and for adenocarcinomas manifesting as subsolid NCNs; 85% (95% CI 81-89%) for adenocarcinoma, 74% (95% CI 63-85%) for squamous cell, 48% (95% CI 34-62%) for small cell. The rank ordering by lead time was the same as the rank ordering by survival rates. The significant differences in the frequency of NCNs and frequency and aggressiveness of diagnosed cancers in baseline and annual repeat need to be recognised for an optimal regimen of screening. • Lung cancer aggressiveness varies considerably by cell type and nodule consistency. • Kaplan-Meier survival rates varied by cell type between 100% and 48%. • The percentages of lung cancers by cell type in screening rounds reflect screening biases. • Rank ordering by cell type survival is consistent with that by lead times. • Empirical evidence provides critical information for the regimen of screening.

Purpose To examine whether traditional and cyber bullying victimization were associated with adolescent's mental health problems and suicidal ideation at two-year follow-up. Gender differences were explored to determine whether bullying affects boys and girls differently. Methods A two-year longitudinal study was conducted among first-year secondary school students (N = 3181). Traditional and cyber bullying victimization were assessed at baseline, whereas mental health status and suicidal ideation were assessed at baseline and follow-up by means of self-report questionnaires. Logistic regression analyses were conducted to assess associations between these variables while controlling for baseline problems. Additionally, we tested whether gender differences in mental health and suicidal ideation were present for the two types of bullying. Results There was a significant interaction between gender and traditional bullying victimization and between gender and cyber bullying victimization on mental health problems. Among boys, traditional and cyber bullying victimization were not related to mental health problems after controlling for baseline mental health. Among girls, both traditional and cyber bullying victimization were associated with mental health problems after controlling for baseline mental health. No significant interaction between gender and traditional or cyber bullying victimization on suicidal ideation was found. Traditional bullying victimization was associated with suicidal ideation, whereas cyber bullying victimization was not associated with suicidal ideation after controlling for baseline suicidal ideation. Conclusions Traditional bullying victimization is associated with an increased risk of suicidal ideation, whereas traditional, as well as cyber bullying victimization is associated with an increased risk of mental health problems among girls. These findings stress the importance of programs aimed at reducing bullying behavior, especially because early-onset mental health problems may pose a risk for the development of psychiatric disorders in adulthood.

Central visual field (VF) damage in glaucoma patients can significantly hinder daily activities. The present study investigates whether the presence of localized baseline damage to the central 10 degrees of the VF is predictive of faster global mean deviation (MD) progression. Prospective cohort study. Eyes from the multicenter African Descent and Glaucoma Evaluation Study (ADAGES) with established glaucoma and VF loss and a minimum of 5 24-2 VFs were eligible. Baseline central 24-2 damage was defined as any of the 12 central-most points with total deviation (TD) values at P < 0.5% on 2 consecutive examinations. Progression was determined using trend-based and event-based criteria: (1) rates of MD change significantly faster than zero and (2) >-5 dB MD loss over the entire follow-up. A total of 827 eyes of 584 patients were studied. Mean rate of MD change of the entire sample was -0.15 dB/year (95% CI: -0.19 to -0.12, P < .001). Eyes with baseline central damage progressed faster than those without (difference: β central = -0.07 dB/year, 95% CI: -0.11 to -0.01, P = .011) and were more likely to experience MD loss greater than 5 dB (hazard ratio = 3.0 [95% CI: 2.1-4.1, P < .001]). These differences remained significant after adjusting for confounders. The presence of central VF damage at baseline is significantly associated with more rapid global progression. Detection of central VF damage aids in stratification of high-risk patients who may need intensive surveillance and aggressive treatment. Copyright © 2018 Elsevier Inc. All rights reserved.

The purpose of the current study was to predict concurrent levels of problem behaviors from young children's baseline cortisol and attachment classification, a proxy for the quality of caregiving experienced. In a sample of 58 children living at or below the federal poverty threshold, children's baseline cortisol levels, attachment classification, and problem behaviors were assessed at 17 months of age. We hypothesized that an interaction between baseline cortisol and attachment classification would predict problem behaviors above and beyond any main effects of baseline cortisol and attachment. However, based on limited prior research, we did not predict whether or not this interaction would be more consistent with diathesis-stress or differential susceptibility models. Consistent with diathesis-stress theory, the results indicated no significant differences in problem behavior levels among children with high baseline cortisol. In contrast, children with low baseline cortisol had the highest level of problem behaviors in the context of a disorganized attachment relationship. However, in the context of a secure attachment relationship, children with low baseline cortisol looked no different, with respect to problem behavior levels, then children with high cortisol levels. These findings have substantive implications for the socioemotional development of children reared in poverty. Copyright © 2017 Elsevier Inc. All rights reserved.

The hemoglobin glycation index (HGI) is known to be correlated with the risk for cardiovascular disease. To analyze the association between incident coronary artery calcification (CAC) and the changes in HGI among participants without diabetes, over 4 years. A retrospective study of 2052 nondiabetic participants in whom the coronary artery calcium score was measured repeatedly over 4 years, as part of a health checkup program in Kangbuk Samsung Hospital in Korea, and who had no CAC at baseline. The HGI was defined as the difference between the measured and predicted hemoglobin A1c (HbA1c) levels. A total of 201 participants developed CAC after 4 years, and the mean baseline HGI was significantly higher in those patients. The incidence of CAC gradually increased from the first to the fourth quartile groups of baseline HGI. The odds ratio (OR) for incident CAC was the highest among the four groups divided by the quartiles of the baseline HGI and was significant after adjustment for confounding variables (vs first quartile group: OR, 1.632; 95% confidence interval, 1.024 to 2.601). The incidence of and risk for CAC development were significantly higher than in other groups compared with the low-to-low group after adjustment for confounding factors; however, when baseline HbA1c level was included in the model, only participants with a low-to-high HGI over 4 years showed a significantly increased OR for CAC development compared with the low-to-low group (OR, 1.722; 95% confidence interval, 1.046 to 2.833). The participants with a high baseline HGI and consistently high HGI showed a higher risk for incident CAC than those with a low baseline HGI. An increased HGI over 4 years significantly increased the risk for CAC regardless of the baseline HbA1c levels. Copyright © 2017 Endocrine Society

Objective: Accurate delivery of torque to implant screws is critical to generate ideal preload in the screw joint and to offer protection against screw loosening. Mechanical torque-limiting devices (MTLDs) are available for this reason. In this study, the accuracy of one type of friction-style and two types of spring-style MTLDs at baseline, following fatigue conditions and sterilization processes were determined. Materials and Methods: Five unused MTLDs were selected from each of Straumann (ITI), Astra TECH and CWM systems. To measure the output of each MTLD, a digital torque gauge with a 3-jaw chuck was used to hold the driver. Force was applied to the MTLDs until either the friction styles released at a pre-calibrated torque value or the spring styles flexed to a pre-calibrated limit (target torque value). The peak torque value was recorded and the procedure was repeated 5 times for each MTLD. Then MTLDs were subjected to fatigue conditions at 500 and 1000 times and steam sterilization processes at 50 and 100 times and the peak torque value was recorded again at each stage. Results: Adjusted difference between measured torque values and target torque values differed significantly between stages for all 3 systems. Adjusted difference did not differ significantly between systems at all stages, but differed significantly between two different styles at baseline and 500 times fatigue stages. Conclusion: Straumann (ITI) devices differed minimally from target torque values at all stages. MTLDs with Spring-style were significantly more accurate than Friction-style device in achieving their target torque values at baseline and 500 times fatigue. PMID:23724209

To examine differences between the baseline-referenced and norm-referenced approaches for determining decrements in Automated Neuropsychological Assessment Metrics Version 4 TBI-MIL (ANAM) performance following mild traumatic brain injury (mTBI). ANAM data were reviewed for 616 US Service members, with 528 of this sample having experienced an mTBI and 88 were controls. Post-injury change scores were calculated for each sub-test: (1) normative change score = in-theater score - normative mean and (2) baseline change score = in-theater score - pre-deployment baseline. Reliable change cut-scores were applied to the change and the resulting frequency distributions were compared using McNemar tests. Receiver operator curves (ROC) using both samples (i.e. mTBI and control) were calculated for the change scores for each approach to determine the discriminate ability of the ANAM. There were no statistical differences, p < 0.05 (Bonferonni-Holm corrected), between the approaches. When the area under the curve for the ROCs were averaged across sub-tests, there were no significant differences between either the norm-referenced (0.65) or baseline-referenced (0.66) approaches, p > 0.05. Overall, the findings suggest there is no clear advantage of using the baseline-referenced approach over norm-referenced approach.

There is insufficient research on whether direct-acting antiviral (DAA) therapy can improve liver fibrosis in patients with chronic hepatitis C virus (HCV). We evaluated sequential changes in liver stiffness using shear wave elastography in patients with HCV who received DAA therapy. A total of 210 patients with HCV who received daclatasvir and asunaprevir therapy and achieved sustained virological response (SVR) were analyzed. Liver stiffness, as evaluated by shear wave elastography, and laboratory data were assessed before treatment (baseline), at end of treatment (EOT), and at 24 weeks after EOT (SVR24). Alanine aminotransferase levels (ALT) decreased over time, and there were significant differences between baseline and EOT and between EOT and SVR24. Although platelet counts did not significantly differ between baseline and EOT, they increased significantly from EOT to SVR24. The median (interquartile range) liver stiffness values at baseline, EOT, and SVR24 were 10.2 (7.7-14.7), 8.8 (7.1-12.1), and 7.6 (6.3-10.3) kPa, respectively (P < 0.001, baseline vs EOT; P < 0.001, EOT vs SVR24). Additionally, in patients with ALT ≤ 30 (indicating low necroinflammatory activity in the liver) and Fibrosis-4 index > 2.0 (n = 75), the liver stiffness values at baseline, EOT, and SVR24 were 9.6 (7.7-15.2), 9.2 (7.3-12.1), and 7.7 (6.3-10.1) kPa, respectively (P < 0.001, baseline vs EOT; P < 0.001, EOT vs SVR24). These results suggest that early improvement of liver stiffness starts during the administration of DAAs in patients who achieve SVR, and this effect is particularly pronounced in patients with progressive liver fibrosis. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

The luteinizing hormone-releasing hormone agonist leuprolide acetate is used commonly to anage reproductive problems in pet birds. To determine the effect of leuprolide acetate on plas a and fecal hormone levels in a psittacine species, a single 800 microg/kg dose of the 30-day depot form of leuprolide acetate was administered IM in 11 healthy, nonbreeding adult Hispaniolan Amazon parrots (Amazona ventralis), and plasma and fecal hormone levels were measured before and after leuprolide administration. At pooled baseline to 21 days postleuprolide acetate administration, sample collection day was significantly associated with plasma 17beta-estradiol and androstenedione levels and fecal 17beta-estradiol levels (evaluated in females only). Both plasma androstenedione and plasma 17beta-estradiol levels decreased significantly from baseline to a nadir at 7 days postleuprolide acetate administration but did not differ significantly 14 days later from that nadir or from pooled baseline samples, suggesting that the effect of leuprolide on hormone levels remained about 2 weeks. Fecal 17beta-estradiol levels increased significantly from the nadir at 7 days postleuprolide to 21 days postleuprolide administration, with trends of the level at 21 days postleuprolide being higher than the pooled baseline level and of decreasing levels from pooled baseline to 7 days postleuprolide administration. Plasma luteinizing hormone and fecal testosterone levels did not change significantly from baseline levels after leuprolide administration over the 2-day period. No significant correlations were found between plasma hormone and fecal hormone levels. These results suggest that measurement of plasma androstenedione, plasma 17beta-estradiol, and fecal 17beta-estradiol levels might be useful in assessing the effects of 30-day depot leuprolide acetate in Hispaniolan Amazon parrots.

Declining cognitive function is relatively common and increasingly prevalent. Studies have shown that different nutrients (e.g., Ginkgo biloba and vitamin E) appear to be effective at improving memory and concentration, while less is known about their effect on immunity. This study investigated the effect of Ginkgo Synergy(®) plus Choline (n = 33) and OPC Synergy(®) plus Catalyn(®) (n = 31) versus placebo (n = 33) in a 6-month, randomized, double-blind trial on cognitive and immune functioning among English-speaking, non-smoking, healthy older adults. The Stroop Color and Word Test, Trail Making Test A and B, Controlled Oral Word Association, Hopkins Verbal Learning, Mini-Mental State Exam, and Digit Symbol were administered at baseline and 3 and 6 months follow-up to assess cognitive functioning. Cytokines and growth factors were measured at baseline and 6 months to assess inflammation and immune functioning. Data were analyzed with linear mixed modeling. No serious adverse events were noted in this study. According to time on the Trail Making Test-B, the Ginkgo Synergy(®) plus Choline arm showed improvement from baseline to 3 months follow-up (mean difference = 24.2; SE = 6.4; 95% CI: 8.6, 39.7; p = 0.01). On the Controlled Oral Word Association Trial-S, the scores significantly increased for the Ginkgo Synergy(®) plus Choline arm from baseline to 6 months follow-up (mean difference = 2.1; SE = 0.8; 95% CI: 0.2, 3.9; p < 0.05) and for the OPC Synergy(®) plus Catalyn(®) arm from baseline to 3 months follow-up (mean difference = 2.1; SE = 0.8; 95% CI: 0.2, 4.0; p < 0.05). Epidermal growth factor significantly decreased from baseline to 6 months follow-up for the Ginkgo Synergy(®) plus Choline arm (mean difference = 120.7; SE = 28.4; 95% CI: 62.6, 178.8; p < 0.001). Our study showed isolated and modest effects of a Ginkgo biloba plus choline-based formula on cognitive and immune functioning among healthy older adults with no history of significant cognitive deficits. Our trial was registered with clinicaltrials.gov (ID: NCT01672359). This study was supported by a grant from Standard Process, Inc.

Some studies have suggested that disorders in the peripheral and central metabolism of serotonin (5-HT) may play a role in the pathophysiology of autistic disorder. This study examines the whole blood concentrations of 5-HT and 5-hydroxy-indoleacetic acid (5-HIAA) in baseline conditions and during a challenge with L-5-OH-tryptophane (5-HTP; 4 mg/kg in non enteric-coated tablets), the precursor of 5-HT, in a study group of 18 male, post-pubertal, Caucasian autistic patients (age 13-19 y.; I.Q.>55) and 20 matched healthy volunteers. In baseline conditions, no significant differences in 5-HT or 5-HIAA levels could be found between autistic youngsters and normal controls. 5-HTP administration significantly increased the levels of 5-HT in autistic youngsters but not in normal controls. Following 5-HTP challenge the 5-HT levels were significantly higher in autistic patients than in healthy volunteers. After challenge with 5-HTP, no significant differences were found in the concentrations of 5-HIAA or the test substance between autistic youngsters and normal controls. Differences in the peripheral metabolism of 5-HT which may not be observed in baseline conditions but which became clear after loading with 5-HTP, suggest that an increased synthesis of 5-HT from its precursor 5-HTP might be a one factor responsible for differences in the serotonergic system between autistic post-pubertal youngsters and normal controls.

To evaluate the efficacy of Kivia powder on supporting overall gut health through the relief of the discomfort of occasional constipation. Randomized, double-blind, placebo-controlled, parallel-group trial. The investigational product for this study was Kivia powder (Vital Food Processors Ltd., Auckland, New Zealand), containing the active ingredient Zyactinase™, 5.5 g taken daily for four weeks. One hundred thirty-eight subjects reporting occasional constipation were screened and 87 were randomized to placebo (n = 44) and product (n = 43). Bowel movement frequency, as measured by both average daily spontaneous bowel movements (SBM) and complete spontaneous bowel movements (CSBM), were the same in both groups at baseline. There were significant increases in spontaneous bowel movements at week 1 (p = 0.001), week 2 (p = 0.001), week 3 (p = 0.000), and week 4 (p = 0.000) compared to baseline. SBM demonstrated significant differences between the treatment group and the placebo group at week 3 (p = 0.000), and week 4 (p = 0.020). The treatment group demonstrated a significantly higher rate of SBM at week 3 (p = 000) and from baseline to week 4 (p = 0.019). Significant increases in complete spontaneous bowel movements were observed at week 1 (p = 0.000), week 2 (p = 0.000), week 3 (p = 0.000), and week 4 (p = 0.000) compared to baseline. Moreover, CSBM was significantly higher for the treatment group compared to placebo at week 2 (p = 0.001). The change in average daily CSBM from baseline to week 2 was significantly higher in the treatment group than in the placebo group (p = 0.004).Abdominal discomfort or pain demonstrated significant differences between groups at week 1 (p = 0.044) and week 3 (p = 0.026). Flatulence was significantly lower for active group compared to placebo at week 2 (p = 0.047) and week 3 (p = 0.023). The number of bowel movements associated with urgency was significantly lower in the treatment group compared to the placebo group at week 3 (p = 0.048). In addition, it was decreased from baseline to week 1 (p = 0.040) and from baseline to week 3 (p = 0.024) in the treatment group, while the placebo group did not report any reductions in bowel urgency. Bowel movements in the treatment arm were significantly smoother and softer by week 2 (p = 0.020) and week 3 (p = 0.041). Treatment with Kivia powder, an extract of kiwifruit containing Zyactinase™, for four weeks was well tolerated and more effective than placebo in gently enhancing bowel movement frequency and reducing abdominal pain and flatulence in subjects with occasional constipation.

Importance Although research on quality of life and dermatologic conditions is well represented in the literature, information on teledermatology’s effect on quality of life is virtually absent. Objective To determine the effect of store and forward teledermatology on quality of life. Design Two-site, parallel-group, superiority randomized controlled trial. Setting Dermatology clinics and affiliated sites of primary care at 2 US Department of Veterans Affairs medical facilities. Participants Patients being referred to a dermatology clinic were randomly assigned, stratified by site, to teledermatology or the conventional consultation process. Among the 392 patients who met the inclusion criteria and were randomized, 326 completed the allocated intervention and were included in the analysis. Interventions Store and forward teledermatology (digital images and a standardized history) or conventional text-based consultation processes were used to manage the dermatology consultations. Patients were followed up for 9 months. Main Outcome Measures The primary end point was change in Skindex-16 scores, a skin-specific quality-of-life instrument, between baseline and 9 months. A secondary end point was change in Skindex-16 scores between baseline and 3 months. Results Patients in both randomization groups demonstrated a clinically significant improvement in Skindex-16 scores between baseline and 9 months with no significant difference by randomization group (P=.66, composite score). No significant difference in Skindex-16 scores by randomization group between baseline and 3 months was found (P=.39, composite score). Conclusions Compared with the conventional consultation process, store and forward teledermatology did not result in a statistically significant difference in skin-related quality of life at 3 or 9 months after referral.

The aim of the present study was to evaluate the adjunctive effect of the local application of a hyaluronan gel to scaling and root planing in the treatment of chronic periodontitis. Twelve patients with chronic periodontitis were recruited to participate in a study with a split-mouth design and provided informed consent. Plaque formation and bleeding on probing were evaluated pretreatment (baseline) and at 1, 4, and 12 weeks post-treatment. Probing depths and attachment levels were evaluated at baseline and at 12 weeks. The patients received full-mouth scaling and root planing. A hyaluronan gel was administered subgingivally in the test sites at baseline and after 1 week. Significant differences between test and control were evaluated using the paired t test, repeated-measures analysis of variance (Wilks lambda), and a non-parametric Wilcoxon signed-rank test. A significant reduction in bleeding on probing scores and probing depths was observed in both groups at 12 weeks (P <0.05). Significantly lower bleeding on probing scores were observed in the hyaluronan group compared to control at 12 weeks (P <0.05). Mean probing depth reductions between baseline and 12 weeks were 1.0 +/- 0.3 mm and 0.8 +/- 0.2 mm for the hyaluronan and control groups, respectively. The difference between the groups was statistically significant (P <0.05). The local application of hyaluronan gel in conjunction with scaling and root planing may have a beneficial effect on periodontal health in patients with chronic periodontitis.

The Idiopathic Intracranial Hypertension Treatment Trial (IIHTT) showed that acetazolamide provided a modest, significant improvement in mean deviation (MD). Here, we further analyze visual field changes over the 6-month study period. Of 165 subjects with mild visual loss in the IIHTT, 125 had perimetry at baseline and 6 months. We evaluated pointwise linear regression of visual sensitivity versus time to classify test locations in the worst MD (study) eye as improving or not; pointwise changes from baseline to month 6 in decibels; and clinical consensus of change from baseline to 6 months. The average study eye had 36 of 52 test locations with improving sensitivity over 6 months using pointwise linear regression, but differences between the acetazolamide and placebo groups were not significant. Pointwise results mostly improved in both treatment groups with the magnitude of the mean change within groups greatest and statistically significant around the blind spot and the nasal area, especially in the acetazolamide group. The consensus classification of visual field change from baseline to 6 months in the study eye yielded percentages (acetazolamide, placebo) of 7.2% and 17.5% worse, 35.1% and 31.7% with no change, and 56.1% and 50.8% improved; group differences were not statistically significant. In the IIHTT, compared to the placebo group, the acetazolamide group had a significant pointwise improvement in visual field function, particularly in the nasal and pericecal areas; the latter is likely due to reduction in blind spot size related to improvement in papilledema.

Intraoperative hypothermia is associated with several unfavorable events; therefore, it is important to prevent the development of hypothermia. Amino acid consumption and/or infusion have been reported to prevent hypothermia. We hypothesized that preoperative carbohydrate-rich beverage (Arginaid Water™) loading can reduce intraoperative hypothermia in rats under general anesthesia. We divided 18 rats into 3 groups (group A, 8 mL/kg of saline; group B, 8 mL/kg of a carbohydrate-rich beverage; and group C, 21 mL/kg of the carbohydrate-rich beverage). The rats were administered each beverage at the above mentioned doses via an oral gastric tube 30 min before the induction of anesthesia. During the 2-h general anesthesia, rectal temperature was measured at 20-min intervals. Serum ketone body concentration was measured at 0 and 120 min. The baseline temperature was not significantly different among the groups. At the end of the experiment, group A showed a significantly greater decrease in temperature from the baseline (5.4 ± 0.8°C) than group B (3.9 ± 0.7°C, P = 0.01) and group C (3.8 ± 0.8°C, P = 0.01). The temperatures in groups B and C were not significantly different. There was no significant change in the serum ketone body concentration from the baseline at the end of the experiment in group A. However, the serum ketone body concentrations in group B and group C were significantly decreased from the baseline. Preoperative carbohydrate loading reduces hypothermia in rats under general anesthesia.

Organizational readiness to change may be a key determinant of implementation success and a mediator of the effectiveness of implementation interventions. If organizational readiness can be reliably and validly assessed at the outset of a change initiative, it could be used to assess the effectiveness of implementation-support activities by measuring changes in readiness factors over time. We analyzed two waves of readiness-to-change survey data collected as part of a three-arm, randomized controlled trial to implement evidence-based health promotion practices in small worksites in low-wage industries. We measured five readiness factors: context (favorable broader conditions); change valence (valuing health promotion); information assessment (demands and resources to implement health promotion); change commitment (an intention to implement health promotion); and change efficacy (a belief in shared ability to implement health promotion). We expected commitment and efficacy to increase at intervention sites along with their self-reported effort to implement health promotion practices, termed wellness-program effort. We compared means between baseline and 15 months, and between intervention and control sites. We used linear regression to test whether intervention and control sites differed in their change-readiness scores over time. Only context and change commitment met reliability thresholds. Change commitment declined significantly for both control (-0.39) and interventions sites (-0.29) from baseline to 15 months, while context did not change for either. Only wellness program effort at 15 months, but not at baseline, differed significantly between control and intervention sites (1.20 controls, 2.02 intervention). Regression analyses resulted in two significant differences between intervention and control sites in changes from baseline to 15 months: (1) intervention sites exhibited significantly smaller change in context scores relative to control sites over time and (2) intervention sites exhibited significantly higher changes in wellness program effort relative to control sites. Contrary to our hypothesis, change commitment declined significantly at both Healthlinks and control sites, even as wellness-program effort increased significantly at HealthLinks sites. Regression to the mean may explain the decline in change commitment. Future research needs to assess whether baseline commitment is an independent predictor of wellness-program effort or an effect modifier of the HealthLinks intervention.

To determine the effects of intravenous and intramuscular xylazine–ketamine on intraocular pressure (IOP) in laboratory rabbits, 10 New Zealand white rabbits received xylazine (0.46 mg/kg) and ketamine (1.5 mg/kg) intravenously whereas another 10 rabbits received intramuscular xylazine (10 mg/kg) and ketamine (50 mg/kg). IOP was measured at baseline and 5, 10, 20, and 25 min after administration in rabbits that were injected intravenously and at baseline and 10, 20, 30, and 45 min in rabbits injected intramuscularly. Baseline IOP (mean ± 1 SD; intravenous group, 20.15 ± 2.24 mm Hg; intramuscular group, 19.03 ± 1.77 mm Hg) did not differ between groups. Compared with baseline values, IOP decreased significantly after intravenous administration at 10, 20, and 25 min (decreases of 2.73, 4.10, and 4.55 mm Hg, respectively) but not at 5 min (decrease of 1.40 mm Hg). IOP in intramuscularly dosed rabbits showed significant differences from baseline at 10, 20, 30, and 45 min (decreases of 2.88, 3.30, 3.95, and 4.60 mm Hg, respectively). In the intravenous group, IOP differed at 10 min compared with 25 min (1.83 mm Hg, P = 0.0143) but not at 20 min compared with 25 min (0.450 mm Hg). In the intramuscular group, differences in IOP at 10 min compared with 20 min, 20 min compared with 30 min, and 30 min compared with 45 min were nonsignificant. Intravenous and intramuscular xylazine–ketamine decreased IOP in laboratory rabbits and may be used safely during ocular procedures for which increased IOP is a concern. PMID:23849448

We analyzed the public STAR*D database to better characterize the baseline clinical characteristics and functional outcomes of patients with major depressive disorder (MDD) who experienced partial response in order to better understand the burden associated with this outcome. Patients (n=2,876) received treatment with citalopram. The last available Quick Inventory of Depressive Symptoms (QIDS-SR) from the 12-week treatment period was used to assign subjects to one of three groups: remitters QIDS-SR≤5; non-responders QIDS-SR >5 and <25% reduction from baseline; and partial responders QIDS-SR >5 and ≥25% reduction from baseline. Baseline sociodemographic and clinical characteristics were compared across groups, as well as functional outcomes at Level 1 exit. RESULTS. Of the 2,876 patients, 943 patients (33%) were classified as remitters, 1069 (37%) as partial responders, and 854 (30%) as non-responders. The groups differed on a number of pre-treatment course of illness variables and comorbidities. In addition, remitters, partial responders, and non-responders all separated on posttreatment quality of life and functional outcomes at Level 1 exit. Partial responders demonstrated significant functional impairment at Level 1 exit, differing significantly from the patients who remitted on quality of life, mental and physical functioning, and social and work-related impairment. Adjusted outcomes showed similar differences. Differences in baseline rates of suicidality, comorbidity, and atypical presentations of depression were also observed between outcome groups. Given the substantial clinical and economic burden associated with functional impairment in depression, the need to fully treat partially responding patients to achieve depression remission and restoration of functioning is highlighted by this work.

To evaluate hypothalamic-pituitary-adrenal (HPA) axis function in patients with recent onset polymyalgia rheumatica (PMR) not previously treated with glucocorticoids; and to detect possible correlations between adrenal hormone levels, interleukin 6 (IL-6), and other acute phase reactants at baseline and during 12 months of glucocorticoid treatment. Forty-one PMR patients of both sexes with recent onset disease and healthy sex and age matched controls were enrolled into a longitudinal study. Patients were monitored for serum cortisol, dehydroepiandrosterone sulfate (DHEAS), androstenedione (ASD), and clinical and laboratory measures of disease activity such as C-reactive protein and IL-6 concentrations at baseline and after 1, 3, 6, 9 and 12 months of glucocorticoid treatment. To assess dynamic HPA axis function, serum cortisol and plasma adrenocorticotropic hormone (ACTH) levels were evaluated in another 8 patients with recent onset PMR not treated with glucocorticoid in comparison to controls after challenge with ovine corticotropin releasing hormone (oCRH) test. In addition, serum cortisol and 17-hydroxyprogesterone (17-OHP) levels were evaluated after stimulation with low dose (1 microg) intravenous ACTH. Serum cortisol and ASD levels of all PMR patients at baseline did not differ from controls. During followup, cortisol levels dipped at one and 3 months. Serum DHEAS levels in all patients were significantly lower than in controls at baseline. In female PMR patients a significant correlation was found at baseline between cortisol levels and duration of disease. Serum concentrations of IL-6 at baseline were significantly higher in PMR patients than in controls. During 12 months of glucocorticoid treatment IL-6 levels dropped significantly at one month; thereafter they remained stable and did not increase again despite tapering of the glucocorticoid dose. After oCRH stimulation, a similar cortisol response was found in patients and controls. After ACTH administration, a significant cortisol peak was detected in patients and controls, whereas no significant difference in cortisol area-under-the-curve (AUC) was found between the groups. In contrast, ACTH induced a significantly higher (p < 0.05) peak of 17-OHP and AUC in PMR patients than in controls. This study found reduced production of adrenal hormones (cortisol, DHEAS) at baseline in patients with active and untreated PMR. The defect seems mainly related to altered adrenal responsiveness to the ACTH stimulation (i.e., increased 17-OHP), at least in untreated patients. The 12 month glucocorticoid treatment of patients reduced the production of inflammatory mediators (i.e., IL-6) in a stable manner that persisted after glucocorticoids were tapered.

Individual response to dietary interventions can be highly variable. The phenotypic characteristics of those who will respond positively to personalised dietary advice are largely unknown. The objective of this study was to compare the phenotypic profiles of differential responders to personalised dietary intervention, with a focus on total circulating cholesterol. Subjects from the Food4Me multi-centre study were classified as responders or non-responders to dietary advice on the basis of the change in cholesterol level from baseline to month 6, with lower and upper quartiles defined as responder and non-responder groups, respectively. There were no significant differences between demographic and anthropometric profiles of the groups. Furthermore, with the exception of alcohol, there was no significant difference in reported dietary intake, at baseline. However, there were marked differences in baseline fatty acid profiles. The responder group had significantly higher levels of stearic acid (18 : 0, P=0·034) and lower levels of palmitic acid (16 : 0, P=0·009). Total MUFA (P=0·016) and total PUFA (P=0·008) also differed between the groups. In a step-wise logistic regression model, age, baseline total cholesterol, glucose, five fatty acids and alcohol intakes were selected as factors that successfully discriminated responders from non-responders, with sensitivity of 82 % and specificity of 83 %. The successful delivery of personalised dietary advice may depend on our ability to identify phenotypes that are responsive. The results demonstrate the potential use of metabolic profiles in identifying response to an intervention and could play an important role in the development of precision nutrition.

Objective To assess the impact of wearing fixed orthodontic appliance (FOA) or clear-aligner, on daily performance in adult patients. Methods The Oral Impacts on Daily Performance (OIDP) index was assessed in 152 adults aged 25–35 years at baseline (T0), 6 months after bonding (T1), and 12 months after bonding (T2). Participants were randomly divided into two groups: CA group (participants treated with clear-aligner) and a control group (FOA group; participants treated with FOA). Baseline malocclusion severity was assessed using the Index of Orthodontic Treatment Need. Results There were no significant differences in sociodemographic variables and OIDP scores at baseline between the two groups. Significant changes in OIDP total and subscale scores were observed while wearing FOA: OIDP total score and subscale scores of eating, cleaning teeth, smiling, and social relation at T1 and T2 were significantly higher than at baseline (P<0.05 or P<0.01). However, only OIDP total score was significantly increased at T1 compared to the baseline in the CA group. OIDP total score and subscale scores of eating, cleaning teeth, smiling, and social relation were significantly higher in patients wearing FOA than in patients wearing clear-aligner at T1 and T2 (P<0.05 or P<0.01). Conclusion Patients wearing clear-aligner have fewer impacts on daily life than those wearing FOA during treatment, and have no significant changes in OIPD subscale scores at 12 months. FOA therapy significantly impacts daily performance in adult patients during treatment. PMID:27616881

To determine the outcome of intervention with a spinal weighted kypho-orthosis (WKO) and a spinal proprioceptive extension exercise dynamic (SPEED) program on the risk of falls in ambulatory community-dwelling persons older than 60 years with osteoporosis-kyphosis at risk for falls. The study had 3 stages. At stage 1 (baseline), the 12 women in the kyphotic group were compared with 13 healthy controls to assess the risk of falls and balance disorder in the kyphotic group. At stage 2, the 12 kyphotic women began the SPEED program with a WKO (2 supervised sessions in an outpatient clinic and a 4-week, daily home-based training program). At stage 3, baseline and follow-up data of the kyphotic group were compared to determine the effect of intervention. At baseline, there were significant differences between the osteoporotic-kyphotic group and the control group in balance (P=.002), gait (P<.05), and strength (P<.05). After a 4-week intervention, comparison of the kyphotic group's baseline and follow-up results showed a significant change in balance (P=.003) and several gait parameters (P<.05). Mean back extensor strength improved significantly from baseline (144.0-46.5 N) to follow-up (198.6+/-55.2 N; P<.001). Lower extremity muscle strength was not changed significantly, except for improved left ankle plantar flexors (P=.02). Back pain decreased significantly (P=.001). Balance, gait, and risk of falls improved significantly with the 4-week SPEED program.

This study compares the effect of heliox-driven to that of air-driven bronchodilator therapy on the pulmonary function test (PFT) in patients with different levels of asthma severity. One-hundred thirty-two participants were included in the study. Participants underwent spirometry twice with bronchodilator testing on two consecutive days. Air-driven nebulization was used one day and heliox-driven nebulization the other day in random order crossover design. After a baseline PFT, each participant received 2.5 mg of albuterol sulfate nebulized with the randomized driving gas. Post bronchodilator PFT was repeated after 30 min. The next day, the exact same protocol was repeated, except that the other driving gas was used to nebulize the drug. Participants were subgrouped and analyzed according to their baseline FEV(1) on day 1: Group I, FEV(1) ≥80 %; Group II, 80 % > FEV(1) > 50 %; Group III, FEV(1) ≤50 %. The proportion of participants with greater than 12 % and 200-mL increases from their baseline FEV(1) and the changes from baseline in PFT variables were compared between heliox-driven versus air-driven bronchodilation therapy. The proportion of participants with >12 % and 200-mL increases from their baseline FEV(1) with air- or heliox-driven bronchodilation was not different with respect to the proportion of participants with baseline FEV(1) ≥80 % (20 vs. 18 %, respectively) and 80 % > FEV(1) > 50 % (36 vs. 43 %, respectively), but it was significantly greater with heliox-driven bronchodilation in participants with FEV(1) ≤50 % (43 vs. 73 %, respectively; p = 0.01). Changes from baseline FVC, FEV(1), FEV(1)/FVC, FEF(25-75) %, FEF(max), FEF(25) %, FEF(50) %, and FEF(75) % were significantly larger with heliox-driven versus air-driven bronchodilation in participants with baseline FEV(1) ≤50 %. Improvements in PFT variables are more frequent and profound with heliox-driven compared to air-driven bronchodilator therapy only in asthmatic patients with baseline FEV(1) ≤50 %.

Aim of this study was to determine the effect of high dose vitamin D given to patients with early diabetic renal disease on systolic and diastolic blood pressure, total cholesterol (TC), low-density lipoproteins (LDL), triglycerides (TG) and high density lipoproteins (HDL) in a randomized controlled trial MATERIALS AND METHOD: Patients with early diabetic nephropathy were recruited. Selected patients were allocated to two groups by Block randomization method. Treatment group received 50,000 IU of vitamin D3 intramuscularly and the control group was given an equal volume of distilled water (0.25mL) monthly for six months. Blood and urine were collected at the baseline for biochemical analyses and blood pressure was measured. After six months all the measurements done at the baseline were repeated. Of 155 patients invited, 85 were randomly assigned to two groups. No significant differences were found between treatment and control groups at the baseline. Vitamin D therapy significantly reduced DBP, total cholesterol and LDL but the between group differences were not significant. There was an increase in HDL cholesterol level in the treatment group while there was no change in the control group Between groups difference was significant (P=<0.001). There was a significant improvement of serum HDL level with six months therapy of high dose vitamin D in patients with early diabetic nephropathy. Copyright © 2017 Diabetes India.

Previous research on smart phone use while driving has primarily focused on phone calls and texting. Drivers are now increasingly using their phone for other activities during driving, in particular social media, which have different cognitive demands. The present study compared the effects of four different smart phone tasks on car-following performance in a driving simulator. Phone tasks were chosen that vary across two factors: interaction medium (text vs image) and task pacing (self-paced vs experimenter-paced) and were as follows: Text messaging with the experimenter (text/other-paced), reading Facebook posts (text/self-paced), exchanging photos with the experimenter via Snapchat (image, experimenter -paced), and viewing updates on Instagram (image, experimenter -paced). Drivers also performed a driving only baseline. Brake reaction times (BRTs) were significantly greater in the text-based conditions (Mean = 1.16 s) as compared to both the image-based conditions (Mean = 0.92 s) and the baseline (0.88 s). There was no significant difference between BRTs in the image-based and baseline conditions and there was no significant effect of task-pacing. Similar results were obtained for Time Headway variability. These results are consistent with the picture superiority effect found in memory research and suggest that image-based interfaces could provide safer ways to “stay connected” while driving than text-based interfaces.

Objective We assessed whether differing autoantibody screening criteria for type 1 diabetes (T1D) prevention trials result in different baseline metabolic profiles of those who screen positive. Methods Diabetes Prevention Trial-Type 1 (DPT-1) participants were screened for islet cell autoantibodies (ICA), whereas TrialNet Natural History Study (TNNHS) participants were screened for biochemical autoantibodies. In both studies, those determined to be autoantibody positive underwent baseline oral glucose tolerance tests (OGTTs) in which glucose and C-peptide were measured. Results The percentage of those with an OGTT in the diabetic range was higher among the DPT-1 participants (10.0% of 956 vs. 6.4% of 645, p<0.01). In a logistic regression analysis with adjustments for age and gender, the difference persisted (p<0.01). Among those in the non-diabetic range (n=860 for DPT-1 and n=604 for the TNNHS), glucose levels were similar at all time points, except for higher fasting glucose levels in the TNNHS participants (p<0.001). There was a higher percentage of impaired fasting glucose in the TNNHS participants (10.9% vs. 6.7%, p<0.01); however, with adjustments for age and gender, there was no longer a significant difference. There was no significant difference in the percentages with IGT. C-peptide levels were much lower in the DPT-1 cohort at all OGTT time points (p<0.001 for all). Discussion Differing criteria for autoantibody screening can result in marked differences in the baseline metabolic profiles of prospective participants of T1D prevention trials. PMID:20522170

We sought to evaluate associations between baseline sphericity index (SI) and clinical outcome, and changes in SI after coronary artery bypass graft (CABG) surgery with or without surgical ventricular reconstruction (SVR) in ischaemic cardiomyopathy patients enrolled in the SVR study (Hypothesis 2) of the Surgical Treatment for Ischemic Heart Failure (STICH) trial. Among 1000 patients in the STICH SVR study, we evaluated 546 patients (255 randomized to CABG alone and 291 to CABG + SVR) whose baseline SI values were available. SI was not significantly different between treatment groups at baseline. After 4 months, SI had increased in the CABG + SVR group, but was unchanged in the CABG alone group (0.69 ± 0.10 to 0.77 ± 0.12 vs. 0.67 ± 0.07 to 0.66 ± 0.09, respectively; P < 0.001). SI did not significantly change from 4 months to 2 years in either group. Although LV end-systolic volume and EF improved significantly more in the CABG + SVR group compared with CABG alone, the severity of mitral regurgitation significantly improved only in the CABG alone group, and the estimated LV filling pressure (E/A ratio) increased only in the CABG + SVR group. Higher baseline SI was associated with worse survival after surgery (hazard ratio 1.21, 95% confidence interval 1.02 - 1.43; P = 0.026). Survival was not significantly different by treatment strategy. Although SVR was designed to improve LV geometry, SI worsened after SVR despite improved LVEF and smaller LV volume. Survival was significantly better in patients with lower SI regardless of treatment strategy. © 2015 The Authors. European Journal of Heart Failure © 2015 European Society of Cardiology.

To assess if rewarming time in finger cooling test (FCT) as an indicator of microvascular dysfunction is abnormal in patients with type 2 diabetes mellitus (T2DM). Forty-three T2DM patients and 48 healthy controls with similarly distributed baseline demographic, clinical and laboratory parameters were subjected to FCT involving 60-second index finger immersion into water at 4°C. Finger temperature was measured before FCT (baseline-T), immediately after cooling stimulus (T0), and at one-minute intervals until baseline-T recovery. Temperature decline amplitude was calculated as the difference between T0 and baseline-T, and rewarming time as time elapsed from T0 to baseline-T recovery. T2DM patients compared with healthy controls had statistically similar baseline-T, significantly larger temperature decline amplitude, significantly lower T0, and significantly longer rewarming time. In T2DM patients, rewarming time positively correlated with T2DM duration (r=0.513, p<0.001) and glycated hemoglobin (HbA1c) level (r=0.446, p=0.003), which also were its independent predictors in multivariate regression analysis. Patients with T2DM display abnormal FCT results suggestive of microvascular dysfunction, with T2DM duration and HbA1c level independently predicting rewarming time. Copyright © 2016.

In three 8-week studies of vilazodone 40 mg/d (NCT00285376, NCT00683592, and NCT01473394) and a 10-week study of vilazodone 20 or 40 mg/d (NCT01473381), adults with major depressive disorder (MDD) showed significantly greater improvement with vilazodone versus placebo in global disease severity as measured by mean change from baseline in Clinical Global Impression of Severity (CGI-S) score. To assess the proportion of patients achieving clinically meaningful improvement, a post hoc pooled analysis was conducted using categorical shifts in disease severity based on CGI-S scores at baseline and end of treatment (EOT). Analyses were conducted in the pooled intent-to-treat population (N=2,218). Definitions of categorical shifts included CGI-S ≥4 (moderately ill or worse) at baseline to CGI-S ≤2 (normal or borderline ill) at EOT; CGI-S ≥5 (markedly ill or worse) at baseline to CGI-S ≤2 at EOT; and CGI-S ≥6 (severely ill or worse) at baseline to CGI-S ≤3 (mildly ill or better) at EOT. At baseline, 2,217 patients were moderately ill or worse. The percentage who improved to normal or borderline ill was significantly higher with vilazodone than with placebo (40.0% versus 27.8%; odds ratio [OR] =1.7, P <0.001; number needed to treat [NNT] =9). In the 979 patients who were markedly ill or worse at baseline, the percentage who improved to normal or borderline ill was significantly higher with vilazodone than with placebo (36.8% versus 25.5%; OR =1.7, P <0.001; NNT =9). The small number of severely ill patients at baseline (n =43) provided inadequate power to detect statistically significant between-group differences, but an NNT =5 was found for improvement to mildly ill or better. Categorical shift analyses, defined using baseline and EOT CGI-S scores, showed that significantly higher proportions of patients had clinically meaningful improvements in global disease severity with vilazodone 20-40 mg/d versus placebo. This type of analysis may be useful for evaluating the effects of antidepressant treatment in adults with MDD.

Background: Quantitative MRI techniques have demonstrated thalamocortical abnormalities in idiopathic generalized epilepsy (IGE). However, there are few studies examining IGE early in its course and the neurodevelopmental course of this region is not adequately defined. Objective: We examined the 2-year developmental course of the thalamus and frontal lobes in pediatric new-onset IGE (i.e., within 12 months of diagnosis). Methods: We performed whole-brain MRI in 22 patients with new-onset IGE and 36 age-matched healthy controls. MRI was repeated 24 months after baseline MRI. Quantitative volumetrics were used to examine thalamic and frontal lobe volumes. Results: The IGE group showed significant differences in thalamic volume within 1 year of seizure onset (baseline) and went on to show thalamic volume loss at a significantly faster rate than healthy control children over the 2-year interval. The control group also showed a significantly greater increase in frontal white matter expansion than the IGE group. In contrast, frontal lobe gray matter volume differences were moderate at baseline and persisted over time, indicating similar developmental trajectories with differences early in the disease process that are maintained. Conclusions: Brain tissue abnormalities in thalamic and frontal regions can be identified very early in the course of IGE and an abnormal trajectory of growth continues over a 2-year interval.

The IGE group showed significant differences in thalamic volume within 1 year of seizure onset (baseline) and went on to show thalamic volume loss at a significantly faster rate than healthy control children over the 2-year interval. The control group also showed a significantly greater increase in frontal white matter expansion than the IGE group. In contrast, frontal lobe gray matter volume differences were moderate at baseline and persisted over time, indicating similar developmental trajectories with differences early in the disease process that are maintained. Brain tissue abnormalities in thalamic and frontal regions can be identified very early in the course of IGE and an abnormal trajectory of growth continues over a 2-year interval.

There are currently limited data about whether the effect of spironolactone in patients with resistant arterial hypertension depends on baseline blood pressure and the presence of a secondary cause of hypertension. Patients with office systolic blood pressure (BP) >140 mmHg or diastolic BP >90 mmHg, despite treatment with at least 3 antihypertensive drugs including a diuretic, were randomly assigned to receive spironolactone or a placebo for 8 weeks in a double-blind, placebo-controlled, multicentre trial (ASPIRANT). Analyses were done with 55 patients treated with spironolactone. The degree of BP reduction after 8 weeks of spironolactone treatment did not differ significantly between the three tertiles of baseline systolic BP and patients with and without a secondary cause of hypertension. The reduction of office systolic, office diastolic BP and office pulse pressure was significantly lower in the highest tertile with baseline diastolic BP > 97 mmHg. Spironolactone treatment is effective to a similar extent both in patients with and without a secondary cause of hypertension and regardless of the baseline value of systolic BP. Less effect of spironolactone was found in patients with the highest baseline diastolic BP.

This article reports adolescent substance use outcomes of universal family and school preventive interventions 5½ years past baseline. Participants were 1677 7th grade students from schools (N = 36) randomly assigned to the school-based Life Skills Training plus the Strengthening Families Program: For Parents and Youth 10–14 (LST + SFP 10–14), LST-alone, or a control condition. Self-reports were collected at baseline, 6 months later following the interventions, then yearly through the 12th grade. Measures included initiation—alcohol, cigarette, marijuana, and drunkenness, along with a Substance Initiation Index (SII)—and measures of more serious use—frequency of alcohol, cigarette, and marijuana use, drunkenness frequency, monthly poly-substance use, and advanced poly-substance use. Analyses ruled out differential attrition. For all substance initiation outcomes, one or both intervention groups showed significant, positive point-in-time differences at 12th grade and/or significant growth trajectory outcomes when compared with the control group. Although no main effects for the more serious substance use outcomes were observed, a higher-risk subsample demonstrated significant, positive 12th grade point-in-time and/or growth trajectory outcomes for one or both intervention groups on all measures. The observed pattern of results likely reflects a combination of predispositions of the higher-risk subsample, the timing of the interventions, and baseline differences between experimental conditions favoring the control group.

Cluster randomised controlled trial. Clusters of adolescents (classrooms of 15- to 16-year-olds) in each school were allocated either into a control group or into an intervention group. The interventions consisted of peer cooperation (peer support) and peer interactive learning (observational learning) facilitated through feedback from a dentist (professional support). Three intervention sessions with preselected pairs of adolescents were delivered in the first three weeks. Gender, family socio-economic status (baseline) and different social-cognitive domain variables (baseline, six, and 12 months) were assessed using a questionnaire. Dental plaque levels were the primary outcome measure and they were measured at baseline, after the intervention measured only in the social-cognitive theory-guided group, at six and 12 months. At the six-month follow-up there was a statistically significant difference in means ± SD between the social-cognitive intervention group (27.4 ± 19.4) and the control group (35.1 ± 20.0). At the 12-month follow-up, there was no statistically significant difference in means ± SD between the social-cognitive intervention group (27.4 ± 18.5) and the control group (31.9 ± 17.8). Variations in dental plaque levels at different time periods were explained by the following predictors: family's socio-economic status, social-cognitive domain variables, group affiliation and baseline plaque levels. Social-cognitive theory-guided interventions improved oral self-care of adolescents in the short term. This improvement lasted only for five months after the intervention was discontinued.

Reasons for the recent mixed success of research into negative symptoms may be informed by conceptualizing negative symptoms as a system that is identifiable from network analysis. We aimed to identify: (I) negative symptom systems; (I) central negative symptoms within each system; and (III) differences between the systems, based on network analysis of negative symptoms for baseline, endpoint and change. Patients with chronic schizophrenia and predominant negative symptoms participated in three clinical trials that compared placebo and amisulpride to 60days (n=487). Networks analyses were computed from the Scale for the Assessment of Negative Symptoms (SANS) scores for baseline and endpoint for severity, and estimated change based on mixed models. Central symptoms to each network were identified. The networks were contrasted for connectivity with permutation tests. Network analysis showed that the baseline and endpoint symptom severity systems formed symptom groups of Affect, Poor responsiveness, Lack of interest, and Apathy-inattentiveness. The baseline and endpoint networks did not significantly differ in terms of connectivity, but both significantly (P<0.05) differed to the change network. In the change network the apathy-inattentiveness symptom group split into three other groups. The most central symptoms were Decreased Spontaneous Movements at baseline and endpoint, and Poverty of Speech for estimated change. Results provide preliminary evidence for: (I) a replicable negative symptom severity system; and (II) symptoms with high centrality (e.g., Decreased Spontaneous Movement), that may be future treatment targets following replication to ensure the curent results generalize to other samples.

In recent years, leading organizations in inflammatory bowel disease (IBD) have developed quality measures for the care of adults with Crohn's disease or ulcerative colitis. We used chart audits to assess the impact of quality improvement educational activities on documented adherence to Physician Quality Reporting System measures for IBD. Twenty community-based gastroenterologists were recruited to participate in baseline chart audits (n = 200), a series of 4 accredited educational activities with feedback, and follow-up chart audits (n = 200). Trained abstractors reviewed randomly selected charts of adults with moderate or severe Crohn's disease. The charts were retrospectively abstracted for physicians' documented performance of the 2013 Physician Quality Reporting System IBD quality measures. We compared the physicians' baseline and posteducation rates of documented adherence with 10 of these measures. In a secondary analysis, we compared preeducation with posteducation difference scores of low-performing physicians, those whose baseline documentation rates were in the lowest quartile, and the rest of the cohort. At baseline, documentation of mean provider-level adherence to the 10 quality measures ranged from 3% to 98% (grand mean = 35.8%). In the overall analysis, baseline and posteducation rates of documented adherence did not differ significantly for any of the measures. However, for 4 measures, preeducation to posteducation difference scores were significantly greater among low performers than physicians in the highest 3 quartiles. The results of this preliminary pragmatic study indicate that quality improvement education affords the potential to improve adherence to Physician Quality Reporting System quality measures for IBD among low-performing gastroenterologists.

Background Correlates of recovery from alcohol dependence have been identified through a variety of study designs characterized by different strengths and limitations. The goal of this study was to compare correlates of recovery based on a 3-year prospective design with those based on cross-sectional analyses of data from the same source. Methods Data from the 2001-2002 Wave 1 and 2004-2005 Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were used to examine baseline characteristics associated with Wave 2 recovery from alcohol dependence, among those who classified with past-year DSM-IV alcohol dependence at Wave 1 (n=1,172). Results Abstinent recovery (AR) was significantly associated with Black/Asian/Hispanic race/ethnicity, children <1 year of age in the household at baseline, attending religious services ≥weekly at follow-up, and having initiated help seeking that comprised/included 12-step participation within <3 years prior to baseline. Nonabstinent recovery (NR) was positively associated with being never married at baseline, having job problems or being unemployed in the year preceding baseline, attending religious services

To determine whether there were ocular surface changes in glaucomatous patients treated with preservatives beta-blockers who switched to preservative-free beta-blockers. This was a prospective, longitudinal, open-labeled study. One hundred thirty-two patients with primary open angle glaucoma treated with a preserved beta-blocker were enrolled. All the patients underwent perimetric and gonioscopic examination, complete ophthalmologic examination, intraocular pressure (IOP) measurements, evaluation of ocular surface, Schirmer's test, blood pressure and heart rate at baseline and 1-3 months after changing the medical treatment to a preservative-free timolol 0.1% (Timogel 0.1; Thea). At baseline, after 1 month and at the end of the study (3 months), all patients underwent a questionnaire on the visual quality and symptoms and on the quality of life (QoL). Data were analyzed by t-test when the distribution of the data was normal, by Mann-Whitney when the distribution was not normal. No significant difference was found for IOP before switching from preserved beta-blockers to preservative-free ones. No significant difference was found in blood pressure and heart rate. However, a statistically significant difference was found for abnormal fluorescein staining of the cornea and conjunctiva, eyelid erythema, conjunctival hyperemia, and follicular hyperplasia. A significant difference was found for break-up time (from 9.38±4.7 s at baseline to 10.64±4.7 s after 3 months) and Schirmer's test (from 12.9±5.96 mm at baseline to 14.2±5.87 mm after 3 months). The questionnaire showed that the patient improved the dryness and foreign body sensation. In glaucomatous patients, preservative-free 0.1 timolol treatment improved their QoL. Similar dry eye signs or symptoms improved after 3 months of treatment reducing dryness, hyperemia, follicular hyperplasia, and foreign body sensation.

To establish whether there was a difference in health-related quality of life (HRQoL) in people with chronic musculoskeletal disorders (PwCMSKD) after participating in a multimodal physiotherapy program (MPP) either two or three sessions a week. Total of 114 PwCMSKD participated in this prospective randomised controlled trial. An individualised MPP, consisting of exercises for mobility, motor-control, muscle strengthening, cardiovascular training, and health education, was implemented either twice a week (G2: n = 58) or three times a week) (G3: n = 56) for 1 year. HRQoL physical and mental health state (PHS/MHS), Roland Morris disability Questionnaire (RMQ), Neck-Disability-Index (NDI) and Western Ontario and McMaster Universities' Arthritis Index (WOMAC) were used to measure outcomes of MPP for people with chronic low back pain, chronic neck pain and osteoarthritis, respectively. Measures were taken at baseline, 8 weeks (8 w), 6 months (6 m), and 1 year (1 y) after starting the programme. No statistically significant differences were found between the two groups (G2 and G3), except in NDI at 8 w (-3.34, (CI 95%: -6.94/0.84, p = 0.025 (scale 0-50)). All variables showed improvement reaching the following values (from baseline to 1 y) G2: PHS: 57.72 (baseline: 41.17; (improvement: 16.55%), MHS: 74.51 (baseline: 47.46, 27.05%), HRQoL 0.90 (baseline: 0.72, 18%)), HRQoL-VAS 84.29 (baseline: 58.04, 26.25%), RMQ 4.15 (baseline: 7.85, 15.42%), NDI 3.96 (baseline: 21.87, 35.82%), WOMAC 7.17 (baseline: 25.51, 19.10%). G3: PHS: 58.64 (baseline: 39.75, 18.89%), MHS: 75.50 (baseline: 45.45, (30.05%), HRQoL 0.67 (baseline: 0.88, 21%), HRQoL-VAS 86.91 (baseline: 52.64, 34.27%), RMQ 4.83 (baseline: 8.93, 17.08%), NDI 4.91 (baseline: 23.82, 37.82%), WOMAC 6.35 (baseline: 15.30, 9.32%). No significant differences between the two groups were found in the outcomes of a MPP except in the NDI at 8 weeks, but both groups improved in all variables during the course of 1 year under study. Implications for Rehabilitation A multimodal physiotherapy program (MPP) improves quality of life, overall health, and function in people with chronic musculoskeletal disease after an intervention of short, medium and long term. This implies that twice a week MPP for people with chronic musculoskeletal pain has comparable results to three times a week provision and therefore may have implications in saving resources and cost for patients and service providers without compromising the outcomes of treatment. These results can be considered not only for therapists, but also for managers who offer the services to optimise the balance cost-effectiveness of the proposed interventions.

Introduction: Preterm premature rupture of membranes (PPROM) can result in fetal complications such as oligohydramnios. This study aimed to determine the effects of intravenous (IV) fluid bolus on amniotic fluid index (AFI) in pregnant women with PPROM. Methods: 24 women with PPROM during singleton live pregnancy of 28 to 34 weeks whose baseline AFI was ≤ 5cm were randomized into two groups. The study group received one liter intravenous fluid bolus of isotonic Ringer serum during 30-minute period. Reevaluations of amniotic fluid index in both groups were made 90 minutes and 48 hours after baseline measurement. Independent t-test and paired t-test were used to compare the two groups and mean amniotic fluid index before and after treatment, respectively. Results: The results of this study demonstrate that AFI decreased statistically significant in both the control and study groups. AFI decreased in both groups at 48 hours later. This decrease was not statistically significant in any group. The mean change in AFI (90 minutes and baseline) and (48 hours and baseline) between the two groups were not significant. The time between mean baseline measurements and delivery were 196.41 and 140.58 hours in the study and control groups, respectively. This difference was not statistically significant. Conclusion: This study did not find significant impact of hydration On AFI as a prophylactic method on oligohydramnios in pregnant women with PPROM. PMID:25276709

To investigate whether the long-term use (6 months) of an arginine-calcium carbonate-MFP toothpaste would affect calculus formation and/or gingivitis when compared to a calcium carbonate-MFP toothpaste. This was a double-blind clinical study. Eligible adult subjects (120) entered a 2-month pre-test phase of the study. After receiving an evaluation of oral tissue and a dental prophylaxis, the subjects were provided with a regular fluoride toothpaste, a soft-bristled adult toothbrush with instructions to brush their teeth for 1-minute twice daily (morning and evening) for 2 months. The subjects were then examined for baseline calculus using the Volpe-Manhold Calculus Index (VMI) and gingivitis using the Löe-Silness Gingival Index (GI), along with an oral tissue examination. Qualifying subjects were randomized to two treatment groups: (1) Colgate Sensitive Pro-Relief toothpaste containing 8.0% arginine, 1450 ppm MFP and calcium carbonate (Test group), or (2) Colgate Cavity Protection toothpaste containing 1450 ppm MFP and calcium carbonate (Control group). Subjects were stratified by the VMI score and gender. After a dental prophylaxis (VMI=0), the subjects entered a 6-month test phase. Each received the assigned toothpaste and a soft-bristled adult toothbrush for home use with instructions of brushing teeth for 1 minute twice daily (morning and evening). The examinations of VMI, Löe-Silness GI and oral tissues were conducted after 3 and 6 months. Prior to each study visit, subjects refrained from brushing their teeth as well as eating and drinking for 4 hours. 99 subjects complied with the study protocol and completed the 6-month test phase. No within-treatment comparison was performed for the VMI because it was brought down to zero after the prophylaxis at the baseline of the test phase. For the Löe-Silness GI, subjects of the Test group exhibited a significant difference from baseline at the 3- and 6-month examinations. The 3-month Löe-Silness GI of the Control group was significantly different from that of the baseline; however, its 6-month Löe-Silness GI was not statistically significantly different from the baseline values. After 3 and 6 months, there were no significant differences between the Test and Control groups with respect to the mean VMI scores; there were no statistically significant differences between the two groups with respect to the Löe-Silness GI results after 3 and 6 months of product use.

Effective interventions are needed to reduce the chronic disease epidemic. The Internet has the potential to provide large populations with individual advice at relatively low cost. The focus of the study was the Web-based tailored physical activity intervention Active-online. The main research questions were (1) How effective is Active-online, compared to a nontailored website, in increasing self-reported and objectively measured physical activity levels in the general population when delivered in a real-life setting? (2) Do respondents recruited for the randomized study differ from spontaneous users of Active-online, and how does effectiveness differ between these groups? (3) What is the impact of frequency and duration of use of Active-online on changes in physical activity behavior? Volunteers recruited via different media channels completed a Web-based baseline survey and were randomized to Active-online (intervention group) or a nontailored website (control group). In addition, spontaneous users were recruited directly from the Active-online website. In a subgroup of participants, physical activity was measured objectively using accelerometers. Follow-up assessments took place 6 weeks (FU1), 6 months (FU2), and 13 months (FU3) after baseline. A total of 1531 respondents completed the baseline questionnaire (intervention group n = 681, control group n = 688, spontaneous users n = 162); 133 individuals had valid accelerometer data at baseline. Mean age of the total sample was 43.7 years, and 1146 (74.9%) were women. Mixed linear models (adjusted for sex, age, BMI category, and stage of change) showed a significant increase in self-reported mean minutes spent in moderate- and vigorous-intensity activity from baseline to FU1 (coefficient = 0.14, P = .001) and to FU3 (coefficient = 0.19, P < .001) in all participants with no significant differences between groups. A significant increase in the proportion of individuals meeting the HEPA recommendations (self-reported) was observed in all participants between baseline and FU3 (OR = 1.47, P = .03), with a higher increase in spontaneous users compared to the randomized groups (interaction between FU3 and spontaneous users, OR = 2.95, P = .02). There were no increases in physical activity over time in any group for objectively measured physical activity. A significant relation was found between time spent on the tailored intervention and changes in self-reported physical activity between baseline and FU3 (coefficient = 1.13, P = .03, intervention group and spontaneous users combined). However, this association was no longer significant when adjusting for stage of change. In a real-life setting, Active-online was not more effective than a nontailored website in increasing physical activity levels in volunteers from the general population. Further research may investigate ways of integrating Web-based physical activity interventions in a wider context, for example, primary care or workplace health promotion.

We examined pelvic floor muscles (PFM) activity (%MVC) in twenty nulliparous women by body position during exercise as well as the activation of abdominal muscles and the gluteus maximus during voluntary contractions of the PFMs. Pelvic floor muscle activity was recorded using a vaginal probe during five experimental trials. Activation of transversus abdominis, rectus abdominis, and gluteus maximus during voluntary PFM contractions was also assessed. Significant differences in mean normalized amplitudes of baseline PFM activity were revealed between standing and lying (P < 0.00024) and lying and ball-sitting positions (P < 0.0053). Average peak, average time before peak, and average time after peak did not differ significantly during the voluntary contractions of the PFMs. Baseline PFM activity seemed to depend on the body position and was the highest in standing. Pelvic floor muscles activity during voluntary contractions did not differ by position in continent women. Statistically significant differences between the supine lying and sitting positions were only observed during a sustained 60-second contraction of the PFMs. PMID:25793212

To perform a worked example of an approach that can be used to identify and remove potentially biased trials from meta-analyses via the analysis of baseline variables. True randomisation produces treatment groups that differ only by chance; therefore, a meta-analysis of a baseline measurement should produce no overall difference and zero heterogeneity. A meta-analysis from the British Medical Journal, known to contain significant heterogeneity and imbalance in baseline age, was chosen. Meta-analyses of baseline variables were performed and trials systematically removed, starting with those with the largest t-statistic, until the I 2 measure of heterogeneity became 0%, then the outcome meta-analysis repeated with only the remaining trials as a sensitivity check. We argue that heterogeneity in a meta-analysis of baseline variables should not exist, and therefore removing trials which contribute to heterogeneity from a meta-analysis will produce a more valid result. In our example none of the overall outcomes changed when studies contributing to heterogeneity were removed. We recommend routine use of this technique, using age and a second baseline variable predictive of outcome for the particular study chosen, to help eliminate potential bias in meta-analyses.

The aim of the study was to evaluate the association between baseline Lipiodol uptake in hepatocellular carcinoma (HCC) after transarterial chemoembolization (TACE) with early tumor recurrence, and to identify a threshold baseline uptake value predicting tumor response. A single-institution retrospective database of HCC treated with Lipiodol-TACE was reviewed. Forty-six tumors in 30 patients treated with a Lipiodol-chemotherapy emulsion and no additional particle embolization were included. Baseline Lipiodol uptake was measured as the mean Hounsfield units (HU) on a CT within one week after TACE. Washout rate was calculated dividing the difference in HU between the baseline CT and follow-up CT by time (HU/month). Cox proportional hazard models were used to correlate baseline Lipiodol uptake and other variables with tumor response. A receiver operating characteristic (ROC) curve was used to identify the optimal threshold for baseline Lipiodol uptake predicting tumor response. During the follow-up period (mean 5.6 months), 19 (41.3%) tumors recurred (mean time to recurrence = 3.6 months). In a multivariate model, low baseline Lipiodol uptake and higher washout rate were significant predictors of early tumor recurrence ( P = 0.001 and < 0.0001, respectively). On ROC analysis, a threshold Lipiodol uptake of 270.2 HU was significantly associated with tumor response (95% sensitivity, 93% specificity). Baseline Lipiodol uptake and washout rate on follow-up were independent predictors of early tumor recurrence. A threshold value of baseline Lipiodol uptake > 270.2 HU was highly sensitive and specific for tumor response. These findings may prove useful for determining subsequent treatment strategies after Lipiodol TACE.

To assess the depressive status and its influence on Chinese HIV-1(+) population, and how it was influenced by highly active antiretroviral therapy (HAART) and the CD4(+) T cell count. Anti-HIV-1(+) patients (age between 18 and 65 years old) who had met the criteria to commence the anti-HIV treatment but had not yet started, were selected from the Beijing Ditan Hospital between March 2011 and June 2012. BDI-II (Beck Depression Inventory) and a self-designed questionnaire were used to evaluate the baseline and the status of 48 weeks post the HAART treatment. Statistically, t test and the Wilcoxon rank sum test were used to compare the BDI scores under different conditions and before/after the HAART. (1) Of 100 subjects: male to female ratio was 99:1; the average age was 31.37 ± 5.58 years; the average education background was of 13.13 ± 3.51 years; the unemployed percentage was 4%; time before being identified as anti-HIV-1(+) was 5.0 (1.0 - 21.0) months; the percentage being infected through homosexual contact was 83%. The baseline BDI score was 6.0 (3 - 10.25). (2) There was no significant difference (P > 0.05) in BDI score between those subjects having had education less or more than 12 years; the BDI score of patients whose anti-HIV-1(+) was significantly higher (P < 0.05) among those discovered within the past 6 months than those more than 6 months. The BDI score of patients whose baseline CD4(+) T cell count below 200 cells/µl was significantly higher (P < 0.05) than those with baseline CD4(+) T cell count greater than 200 cells/µl. The CD4(+) T cell count was significantly high (P < 0.001) after 48 weeks of anti-viral treatment, but the BDI score was not significantly different (P > 0.05). There was no significant change (P > 0.05) in the proportion of patients with different degrees of BDI score before and after 48 weeks of antiviral treatment. Depression in HIV patients was most overt in the first six months when they were aware of the infection. The degree of depression was more severe in patients with baseline CD4(+) T cell count less than 200 cells/µl with improvement of immunity after the HAART did not alleviate the level of depression.

Objective To identify the clinical characteristics of proper robot-assisted gait training group using exoskeletal locomotor devices in non-ambulatory subacute stroke patients. Methods A total of 38 stroke patients were enrolled in a 4-week robotic training protocol (2 sessions/day, 5 times/week). All subjects were evaluated for their general characteristics, Functional Ambulatory Classification (FAC), Fugl-Meyer Scale (FMS), Berg Balance Scale (BBS), Modified Rankin Scale (MRS), Modified Barthel Index (MBI), and Mini-Mental Status Examination (MMSE) at 0, 2, and 4 weeks. Statistical analysis were performed to determine significant clinical characteristics for improvement of gait function after robot-assisted gait training. Results Paired t-test showed that all functional parameters except MMSE were improved significantly (p<0.05). The duration of disease and baseline BBS score were significantly (p<0.05) correlated with FAC score in multiple regression models. Receiver operating characteristic (ROC) curve showed that a baseline BBS score of '9' was a cutoff value (AUC, 0.966; sensitivity, 91%–100%; specificity, 85%). By repeated-measures ANOVA, the differences in improved walking ability according to time were significant between group of patients who had baseline BBS score of '9' and those who did not have baseline BBS score of '9' Conclusion Our results showed that a baseline BBS score above '9' and a short duration of disease were highly correlated with improved walking ability after robot-assisted gait training. Therefore, baseline BBS and duration of disease should be considered clinically for gaining walking ability in robot-assisted training group. PMID:27152266

Disaster triage training for emergency medical service (EMS) providers is not standardized. Simulation training is costly and time-consuming. In contrast, educational video games enable low-cost and more time-efficient standardized training. We hypothesized that players of the video game "60 Seconds to Survival" (60S) would have greater improvements in disaster triage accuracy compared to control subjects who did not play 60S. Participants recorded their demographics and highest EMS training level and were randomized to play 60S (intervention) or serve as controls. At baseline, all participants completed a live school-shooting simulation in which manikins and standardized patients depicted 10 adult and pediatric victims. The intervention group then played 60S at least three times over the course of 13 weeks (time 2). Players triaged 12 patients in three scenarios (school shooting, house fire, tornado), and received in-game performance feedback. At time 2, the same live simulation was conducted for all participants. Controls had no disaster training during the study. The main outcome was improvement in triage accuracy in live simulations from baseline to time 2. Physicians and EMS providers predetermined expected triage level (RED/YELLOW/GREEN/BLACK) via modified Delphi method. There were 26 participants in the intervention group and 21 in the control group. There was no difference in gender, level of training, or years of EMS experience (median 5.5 years intervention, 3.5 years control, p = 0.49) between the groups. At baseline, both groups demonstrated median triage accuracy of 80 percent (IQR 70-90 percent, p = 0.457). At time 2, the intervention group had a significant improvement from baseline (median accuracy = 90 percent [IQR: 80-90 percent], p = 0.005), while the control group did not (median accuracy = 80 percent [IQR:80-95], p = 0.174). However, the mean improvement from baseline was not significant between the two groups (difference = 6.5, p = 0.335). The intervention demonstrated a significant improvement in accuracy from baseline to time 2 while the control did not. However, there was no significant difference in the improvement between the intervention and control groups. These results may be due to small sample size. Future directions include assessment of the game's effect on triage accuracy with a larger, multisite site cohort and iterative development to improve 60S.

The on-field diagnosis of sports-related concussion (SRC) is complicated by the lack of an accurate and objective marker of brain injury. To compare subject-specific changes in the astroglial protein, S100B, before and after SRC among collegiate and semi-professional contact sport athletes, and compare these changes to differences in S100B before and after non-contact exertion. Longitudinal cohort study. From 2009-2011, we performed a prospective study of athletes from Munich, Germany, and Rochester, New York, USA. Serum S100B was measured in all SRC athletes at pre-season baseline, within 3 hours of injury, and at days 2, 3 and 7 post-SRC. Among a subset of athletes, S100B was measured after non-contact exertion but before injury. All samples were collected identically and analyzed using an automated electrochemiluminescent assay to quantify serum S100B levels. Forty-six athletes (30 Munich, 16 Rochester) underwent baseline testing. Thirty underwent additional post-exertion S100B testing. Twenty-two athletes (16 Rochester, 6 Munich) sustained a SRC, and 17 had S100B testing within 3 hours post-injury. The mean 3-hour post-SRC S100B was significantly higher than pre-season baseline (0.099±0.008 µg/L vs. 0.058±0.006 µg/L, p = 0.0002). Mean post-exertion S100B was not significantly different than the preseason baseline. S100B levels at post-injury days 2, 3 and 7 were significantly lower than the 3-hour level, and not different than baseline. Both the absolute change and proportional increase in S100B 3-hour post-injury were accurate discriminators of SRC from non-contact exertion without SRC (AUC 0.772 and 0.904, respectively). A 3-hour post-concussion S100B >0.122 µg/L and a proportional S100B increase of >45.9% over baseline were both 96.7% specific for SRC. Relative and absolute increases in serum S100B can accurately distinguish SRC from sports-related exertion, and may be a useful adjunct to the diagnosis of SRC.

The present study is the first to simultaneously and continuously measure oxygen consumption (MO(2)) and gastrointestinal blood flow (q(gi)) in fish. In addition, while it is the first to compare the effects of three isoenergetic diets on q(gi) in fish, no significant differences among diets were found for postprandial MO(2), q(gi) or heart rate (f(H)) in rainbow trout, Oncorhynchus mykiss. Postprandial q(gi), f(H) and MO(2) were significantly elevated above baseline levels by 4 h. Postprandial q(gi) peaked at 136% above baseline after 11 h, f(H) peaked at 110% above baseline after 14 h and MO(2) peaked at 96% above baseline after 27 h. Moreover, postprandial MO(2) remained significantly elevated above baseline longer than q(gi) (for 41 h and 30 h, respectively), perhaps because most of the increase in MO(2) associated with feeding is due to protein handling, a process that continues following the absorption of nutrients which is thought to be the primary reason for the elevation of q(gi). In addition to the positive relationships found between postprandial MO(2) and q(gi) and between postprandial MO(2) and f(H), we discovered a novel relationship between postprandial q(gi) and f(H).

Present study evaluates efficacy of Trifala and Ela as plaque controlling agent and compares it with chlorhexidine. To evaluate Antigingivitis, Antiplaque and Antihalitosis effect of Triphala and Ela decoction. A randomized sample of 60 patients with plaque induced gingivitis was enrolled and equally divided into two groups group A and group B. Group A was given Trifala and Ela decoction and Group B Chlorehexidine mouthwash for 21 days twice daily. Gingival inflammation index, plaque index and Organoleptic scoring scale was recorded at baseline, 14th day and 21st day. Comparing the plaque index for Group A with group B the reduction in from baseline to 14 day was 42.59 % and 38.62% respectively while from baseline to 21 day was 56.20% and 68.57% respectively. On comparing Gingival index for group A with group B the reduction from baseline to 14 day was 31.95% and 38.62 % respectively while from baseline to 21 day was 69.95 % and 68.57% respectively. Halitosis Percentage reduction at 14th day from base line was 33.33% and 38.18%; at 21 day from baseline 66.66% and 72.72% respectively for group A and group B. No statistical significant difference for intergroup comparison was found using paired t test. Intra group analysis using unpaired t test was significant for all the indices at different time intervals. Triphala and Ela decoction is organic, easy to prepare economical and equally effective as compared to chlorhexidine mouthwash. © The Author(s) 2016.

Epilepsy is characterized by unpredictable and sudden paroxysmal neuronal firing occurrences and sometimes evolving in clinically evident seizure. To predict seizure event, small-world characteristic in nine minutes before seizure, divided in three 3-min periods (T0, T1, T2) were investigated. Intracerebral recordings were obtained from 10 patients with drug resistant focal epilepsy examined by means of stereotactically implanted electrodes; analysis was focused in a period of low spiking (Baseline) and during two seizures. Networks' architecture is undirected and weighted. Electrodes' contacts close to epileptic focus are the vertices, edges are weighted by mscohere (=magnitude squared coherence). Differences were observed between Baseline and T1 and between Baseline and T2 in theta band; and between Baseline and T1, Baseline and T2, and near-significant difference between T0 and T2 in Alpha 2 band. Moreover, an intra-band index was computed for small worldness as difference between Theta and Alpha 2. It was found a growing index trend from Baseline to T2. Cortical network features a specific pre-seizure architecture which could predict the incoming epileptic seizure. Through this study future researches could investigate brain connectivity modifications approximating a clinical seizure also in order to address a preventive therapy.

Purpose This post hoc analysis of the Medical Therapy of Prostatic Symptoms (MTOPS) trial examined the effect of finasteride alone compared to placebo on clinical progression of benign prostatic hyperplasia (BPH) in men with baseline prostate volume (PV) <30 mL and ≥30 mL. Materials and Methods Men were randomized to placebo (n=737), doxazosin alone (4 to 8 mg) (n=756), finasteride alone (5 mg) (n=768), or doxazosin plus finasteride (n=786) (average duration of follow-up was 4.5 yrs); ~50% of patients had a baseline PV ≥30 mL. The present analysis was based on the finasteride alone and placebo arms only and included patients for whom baseline and end of study data were available. We examined the effect of treatment on the cumulative percentage of men who did not experience clinical progression of BPH by study end. Results In men with baseline PV ≥30 mL, treatment with finasteride produced a significant (p<0.001) increase relative to placebo in the cumulative percentage of patients who did not experience clinical progression of BPH (finasteride, 88.1%, versus placebo, 77.8%). There was no significant (p=0.441) between-group difference in men with baseline PV <30 mL (91.4% versus 89.1%, respectively). Conclusions Long-term treatment with finasteride led to a significant beneficial effect compared to placebo on clinical progression of BPH in LUTS patients with enlarged prostates (baseline PV ≥30 mL). Finasteride had no significant effect, compared to placebo on clinical progression of BPH in LUTS patients with smaller prostates (baseline PV <30 mL). PMID:21334655

This study evaluates the relationship between plasma homovanillic acid (pHVA) levels, which have been used to study the role of central dopamine in schizophrenia, and the positive/negative syndrome in first episode schizophrenic patients before and after antipsychotic treatment. Forty neuroleptic-naive first episode schizophrenic patients were monitored at baseline and on days 7, 14 and 28. Clinical status was evaluated with the Scale for the Assessment of Positive Symptoms (SAPS), the Scale for the Assessment of Negative Symptoms (SANS), and the Brief Psychotic Rating Scale. Plasma HVA levels were also measured. Patients were divided into predominantly positive or negative syndrome groups by subtracting SAPS from SANS scores, at baseline. A healthy control group was also enrolled. Schizophrenic patients as a group had significantly higher pHVA levels than controls at baseline (20.50+/-11.85 vs. 13.04+/-7.22 ng/ml). Moreover, 12 predominantly negative syndrome patients had similar mean baseline pHVA levels (21.30+/-12.36 ng/ml) to those of 28 predominantly positive syndrome patients (19.40+/-11.33 ng/ml). During follow-up, there was a different evolution of pHVA levels in the predominantly positive syndrome group than in the predominantly negative syndrome group, with a significantly greater global reduction of pHVA levels in the former. Although both groups showed clinical improvement following 4 weeks of treatment with risperidone, pHVA levels at endpoint were lower (13.29+/-5.91 ng/ml) than at baseline in patients in the predominantly positive syndrome group, while among those in the predominantly negative syndrome group there was no difference in pHVA levels before and after treatment (21.02+/-13.06 ng/ml). The different pHVA level profiles observed in predominantly positive and negative syndrome first episode patients after 4 weeks of treatment with risperidone suggest that each syndrome may have a different underlying neurobiology.

The broadly used combination of metformin and sulphonylurea (SU) often fails to bring patients to glycaemic goal. This study assessed the efficacy and safety of vildagliptin as add-on therapy to metformin plus glimepiride combination in patients with type 2 diabetes mellitus (T2DM) who had inadequate glycaemic control. A multicentre, double-blind, placebo-controlled study randomized patients to receive treatment with vildagliptin 50 mg bid (n = 158) or placebo (n = 160) for 24 weeks. After 24 weeks, the adjusted mean change in haemoglobin A1c (HbA1c) was -1.01% with vildagliptin (baseline 8.75%) and -0.25% with placebo (baseline 8.80%), with a between-treatment difference of -0.76% (p < 0.001). Significantly more patients on vildagliptin achieved the HbA1c target <7% (28.3% vs. 5.6%; p < 0.001). The difference in fasting plasma glucose reduction between vildagliptin and placebo was -1.13 mmol/l (p < 0.001). In subgroup of patients with baseline HbA1c ≤8%, vildagliptin reduced HbA1c by 0.74% from baseline 7.82% (between-treatment difference: -0.97%; p < 0.001) with significantly more patients achieving the HbA1c target <7% (38.6% vs. 13.9%; p = 0.014). Vildagliptin was well tolerated with low incidence of hypoglycaemia, slightly higher than with placebo (5.1% vs. 1.9%) and no clinically relevant weight gain. Vildagliptin significantly improved glycaemic control in patients with T2DM inadequately controlled with metformin plus glimepiride combination. The addition of vildagliptin was well tolerated with low risk of hypoglycaemia and weight gain. This makes vildagliptin an attractive treatment option for patients failing on metformin plus SU particularly in patients with baseline HbA1c ≤8%. © 2013 The Authors.

Erectile dysfunction (ED) is observed frequently in patients with end-stage renal disease, hemodialysis patients, and renal allograft recipients. There are few studies of sildenafil use in renal allograft recipients. The study is designed as a randomized, double-blind, placebo-controlled, crossover trial. Efficacy was assessed by using the self-administered International Index of Erectile Function (IIEF), a 15-question validated measure of ED, and a global efficacy question (Did the treatment improve your erection?). Thirty-two eligible renal transplant recipients were included in this study. After treatment with sildenafil citrate, patients had significantly better scores in 13 of 15 questions, except for questions 11 (desire frequency; P = 0.39) and 12 (desire level; P = 0.61). Treatment efficacy assessed through questions 3 (penetration ability; P < 0.001) and 4 (maintenance frequency; P < 0.001) was significantly better after sildenafil therapy. There were no significant differences between baseline and post-placebo treatment scores, except for question 13 (relationship satisfaction). Patients treated with sildenafil had significantly better scores in 4 domains compared with baseline, but a difference was not observed in the sexual desire domain (P = 0.32). There were no significant differences in scores between placebo and baseline in any domain. On the global efficacy question, 81.3% of patients showed improvement compared with 18.7% with placebo. There were no differences in areas under the curve and maximum cyclosporine concentrations before and after sildenafil therapy. No patient discontinued the drug because of side effects except for 1 patient with visual hallucination. Treatment with sildenafil in renal transplant recipients is a valid option with an effective response.

Objective: To compare the effects of two auditory methods by mother and fetus on the results of NST in 2011-2012. Materials and methods: In this single-blind clinical trial, 213 pregnant women with gestational age of 37-41 weeks who had no pregnancy complications were randomly divided into 3 groups (auditory intervention for mother, auditory intervention for fetus, and control) each containing 71 subjects. In the intervention groups, music was played through the second 10 minutes of NST. The three groups were compared regarding baseline fetal heart rate and number of accelerations in the first and second 10 minutes of NST. The data were analyzed using one-way ANOVA, Kruskal-Wallis, and paired T-test. Results: The results showed no significant difference among the three groups regarding baseline fetal heart rate in the first (p = 0.945) and second (p = 0.763) 10 minutes. However, a significant difference was found among the three groups concerning the number of accelerations in the second 10 minutes. Also, a significant difference was observed in the number of accelerations in the auditory intervention for mother (p = 0.013) and auditory intervention for fetus groups (p < 0.001). The difference between the number of accelerations in the first and second 10 minutes was also statistically significant (p = 0.002). Conclusion: Music intervention was effective in the number of accelerations which is the indicator of fetal health. Yet, further studies are required to be conducted on the issue. PMID:27385971

Objective: To compare the differences of CD(4) (+) T lymphocyte (CD(4)) counts between patients aged 18 and over, to explore the effect of age on treatment, 36 months after having received the China National Free AIDS Antiretroviral Treatment on HIV/AIDS. Methods: Through the National ART Information Ssystem, we selected those HIV/AIDS patients who initiated the ART 36 months after the ART, between January 1, 2010 and December 31, 2012 in Guangzhou, Liuzhou and Kunming. Patients were divided into age groups as 18-49, 50-59 and 60 or over year olds, at the baseline of treatment. Under different levels of baseline CD(4) counts, we chose the baseline and different time-point of CD(4) counts as dependent variables, applied mixed linear model to analyze the effects of age, viral suppression, gender, baseline CD(4)/CD(8) ratio and initial treatment regimen. Results: A total of 5 331 HIV/AIDS patients were recruited. No differences were found on age group ratios between different levels of baseline CD(4) counts. At the level of baseline CD(4)<200 cells/μl, both the 50-59 and 60 or above years old groups had lower CD(4) counts than the 18-49 year-old group, within 36 months after the initiation of ART. However, at the baseline CD(4) level of 200-350 cells/μl, no significant differences on CD(4) counts between the 50-59 year-old and 18-49 year-old groups were noticed. CD(4) counts seemed lower in the 60 and above year-old group than in the 18-49 year-old group. Conclusion: Age might serve as an influencing factor on CD(4) counts within 36 months after the initiation of ART, suggesting that earlier initiation of ART might be of help to the recovery of immune function in the 50-59 year-old group.

To investigate the association among religiosity and depression, anxiety, and quality of life in women with breast cancer. The sample consisted of 284 patients with breast cancer who were undergoing surgery. They were assessed with the following instruments at baseline and at 1 year after surgery: the Duke Religious Index (DRI), the Montgomery-Asberg Depression Rating Scale, the Hospital Anxiety Depression Scale, and the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30. Depression was diagnosed with the Mini International Neuropsychiatric Interview. The prevalence of depression at baseline and at 1 year was 22.5% and 16.5%, respectively. The religious groups did not differ significantly with respect to the prevalence of depression or scores on psychiatric measures at either baseline or at 1 year. The prevalence of depression significantly decreased only in the Protestant group, from 30.1% to 15.7%. Scores on the DRI were significantly negatively correlated with scores on all of the anxiety and depression scales at 1 year after surgery in this group. In contrast, scores on the religious activity subscale of the DRI were significantly positively correlated with scores on the Hospital Anxiety Depression Scale at baseline or at 1 year among Catholic participants. The DRI scores of Protestant respondents were significantly positively correlated with scores on the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 at 1 year after surgery. Religiosity plays an important role in the emotional state and quality of life of Korean women with breast cancer. However, its clinical meaning may differ according to the type of religious affiliation and the stage of illness. Copyright © 2012 John Wiley & Sons, Ltd.

AIM To evaluate the refractive correction for standard automated perimetry (SAP) in eyes with refractive multifocal contact lenses (CL) in healthy young participants. METHODS Twenty-nine eyes of 29 participants were included. Accommodation was paralyzed in all participants with 1% cyclopentolate hydrochloride. SAP was performed using the Humphrey SITA-standard 24-2 and 10-2 protocol under three refractive conditions: monofocal CL corrected for near distance (baseline); multifocal CL corrected for distance (mCL-D); and mCL-D corrected for near vision using a spectacle lens (mCL-N). Primary outcome measures were the foveal threshold, mean deviation (MD), and pattern standard deviation (PSD). RESULTS The foveal threshold of mCL-N with both the 24-2 and 10-2 protocols significantly decreased by 2.2-2.5 dB (P<0.001), while that of mCL-D with the 24-2 protocol significantly decreased by 1.5 dB (P=0.0427), as compared with that of baseline. Although there was no significant difference between the MD of baseline and mCL-D with the 24-2 and 10-2 protocols, the MD of mCL-N was significantly decreased by 1.0-1.3 dB (P<0.001) as compared with that of both baseline and mCL-D, with both 24-2 and 10-2 protocols. There was no significant difference in the PSD among the three refractive conditions with both the 24-2 and 10-2 protocols. CONCLUSION Despite the induced mydriasis and the optical design of the multifocal lens used in this study, our results indicated that, when the dome-shaped visual field test is performed with eyes with large pupils and wearing refractive multifocal CLs, distance correction without additional near correction is to be recommended.

Follistatin levels have recently been considered as a marker for inflammation. Our objective was to evaluate the level of circulating follistatin and high-sensitivity C-reactive protein (hsCRP) in women with polycystic ovary syndrome (PCOS) after oral contraceptive (OC) treatment. A total of 56 Taiwanese women with PCOS were enrolled in this prospective observational study in which they were treated for 3 months with OCs (ethinyl estradiol-cyproterone acetate). Blood samples were taken at baseline after treatment during the withdrawal bleed. Body mass index (BMI), lipid profiles, plasma follistatin, hsCRP, fasting glucose, insulin for the homeostasis model assessment of insulin resistance (HOMA-IR) and hormone profiles were measured and analyzed. Total testosterone, free androgen index (FAI), dehydroepiandrosterone sulfate (DHEAS), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol levels were significantly lower, but total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, circulating follistatin and hsCRP were significantly higher than baseline in women with PCOS after treatment with OCs. An elevation of fasting insulin, HOMA-IR and hsCRP after OC treatment was more evident in non-obese than obese women, whereas the elevation of follistatin was significant in both obese and non-obese women. Follistatin and hsCRP levels all showed significant correlations with each other at baseline and after treatment. The differences in follistatin and hsCRP levels from baseline to after OC treatment were significantly associated with the difference in triglyceride levels. Both hsCRP and follistatin levels increase after OC treatment in women with PCOS. Follistatin seems more sensitive than hsCRP alone to represent the aggravated low-grade inflammatory status after OC treatment in obese and non-obese women with PCOS.

Rosmarinus officinalis L. is a medicinal plant with diverse activities including enhancement microcapillary perfusion. The present study aimed to investigate the clinical efficacy of rosemary oil in the treatment of androgenetic alopecia (AGA) and compare its effects with minoxidil 2%. Patients with AGA were randomly assigned to rosemary oil (n = 50) or minoxidil 2% (n = 50) for a period of 6 months. After a baseline visit, patients returned to the clinic for efficacy and safety evaluations every 3 months. A standardized professional microphotographic assessment of each volunteer was taken at the initial interview and after 3 and 6 months of the trial. No significant change was observed in the mean hair count at the 3-month endpoint, neither in the rosemary nor in the minoxidil group (P > .05). In contrast, both groups experienced a significant increase in hair count at the 6-month endpoint compared with the baseline and 3-month endpoint (P < .05). No significant difference was found between the study groups regarding hair count either at month 3 or month 6 (> .05). The frequencies of dry hair, greasy hair, and dandruff were not found to be significantly different from baseline at either month 3 or month 6 trial in the groups (P > .05). The frequency of scalp itching at the 3- and 6-month trial points was significantly higher compared with baseline in both groups (P < .05). Scalp itching, however, was more frequent in the minoxidil group at both assessed endpoints (P < .05). The findings of the present trial provided evidence with respect to the efficacy of rosemary oil in the treatment of AGA.

The aim of this study was to investigate the long-term effect of acupuncture for treatment of tinnitus. This study is a randomized, patient- and assessor-blind, sham-acupuncture-controlled, pilot trial. Participants were adults (18-60 years old) with chronic (≥6 months), unilateral tinnitus, and without moderate or severe hearing loss. Thirty-three (33) participants were randomized to one of two treatment groups: real acupuncture and sham-acupuncture (nonmeridian; no specific response, de qi). Participants received 10 sessions of acupuncture treatment (twice a week for 5 weeks), and usual patient care education. The subjective outcome was the score of Tinnitus Handicap Inventory (THI) and Visual Analogue Scale (VAS) from baseline to 3 months after. Pure Tone Average (PTA) and Speech Discrimination (SD) from baseline to 3 months after were assessed as objective outcomes. A significant interaction between time and group in VAS (p=0.017) was evident, but not in THI, PTA, and SD scores. THI showed significant improvement at the end of treatment and 3 months after, compared to baseline, in real acupuncture (p=0.004). In SD, a significant long-term effect of real acupuncture was observed until 3 months after (p=0.011). However, the effect of real acupuncture in PTA was not maintained until 3 months after the end of treatment. No significant difference in the sham-acupuncture treatment group was evident. No statistical difference in any outcome was observed between real and sham acupuncture. Only in the mean percent change of VAS, real acupuncture showed statistical significance, compared with sham-acupuncture from baseline to 3 months after (p=0.019). Through evaluation of subjective (THI and VAS) and objective outcomes (PTA and SD), this study demonstrates the long-term effect of real acupuncture.

The purpose of the study was to investigate the effect of different ventilatory strategies on local and systemic cytokine production in swine with intact lungs in vivo after 4 h of mechanical ventilation. Twenty-five swine were anesthetized and then randomized into five groups (n = 5): (1) low tidal volume zero PEEP (LVZP); (2) medium tidal volume zero PEEP (MVZP); (3) high tidal volume zero PEEP (HVZP); (4) low tidal volume PEEP (LVP); (4) high tidal volume PEEP (HVP). Respiratory rate was adjusted to maintain normocapnia and fraction of inspired oxygen (FiO2) was 1.0. TNF-alpha and IL-10 were measured in BALF and serum at baseline, 2 h, and 4 h of MV. One animal in LVZP (2 h) and two in HVP (3 h) group died before the end of the experiment. TNF-alpha level in BALF was significantly higher in LVZP and LVP at 4 h compared to baseline and the other groups. IL-10 level in BALF was significantly higher in LVP at 4h compared to baseline and the other groups. There was a statistically significant increase in serum TNF-alpha levels at 4 h in LVP group compared to baseline and the other groups at 4 h. There was statistically significant increase in serum IL-10 levels in HVZP and LVP groups at 2 and 4 h which was significantly higher compared to the other groups at 4 h. Our results show that a) low volume MV may induce local and systemic pro- and anti-inflammatory cytokine increase b) in the presence of pro-inflammatory cytokine response there is also an anti-inflammatory response in the same compartment (lungs, circulation). c) There maybe loss of alveolar-to-systemic cytokine compartmentalization.

To examine the patterns of myopigenic activity (high near work, low time outdoors) in children growing up in Sydney, Australia, by age, ethnicity and gender. The Sydney Adolescent Vascular and Eye Study (SAVES) re-examined children from the two age cohorts (6 and 12 years at baseline) from the Sydney Myopia Study (SMS). At 5-6 year follow-up, 863 in the younger cohort and 1196 in the older cohort had complete refraction data. Cycloplegic autorefraction (cyclopentolate 1%; Canon RK-F1) was measured at baseline and follow-up. Children who became myopic (≤-0.50 dioptres spherical equivalent refraction) were those classified as non-myopic at baseline and myopic at follow-up. A detailed questionnaire was administered to measure weekly activities, including time spent outdoors and near work at both baseline and follow-up examination. Overall, 128 (14.8%) children in the younger cohort and 210 (17.6%) in the older cohort became myopic. At follow-up, for both cohorts, children had significantly reduced the amount of time spent outdoors (younger cohort, p = 0.001, older cohort, p < 0.0001) and increased near work time (younger cohort, p < 0.0001, older cohort, p = 0.006). Children of East Asian ethnicity spent significantly less time outdoors by more than 7 h per week (both cohorts at baseline and follow-up, all p < 0.0001) and more time in near work activities by close to 3 h compared to European Caucasian children at all ages examined (both cohorts at baseline and follow-up all, p < 0.03). The average pattern of activity for girls differed from that of boys in a similar way (both cohorts at baseline and follow-up all, p < 0.0001). The two independent samples of 12 year-old children provided by follow-up in the younger cohort and baseline in the older cohort gave very similar answers to the questionnaire, with significant differences only evident for computer use (p = 0.001) and books read (p < 0.0001). Answers to the activity questionnaire were very similar in the two cohorts of 12 year-olds, suggesting that the questionnaire gives reproducible answers. However, further work is required for validation. Children's pattern of activities become more myopigenic with age, and differed by gender and by ethnicity at all ages, with girls having a more myopigenic activity pattern than boys, and children of East Asian ancestry having a more myopigenic activity pattern than European Caucasian children.

The aim was to describe vitamin D status and its association with changes in PF during 12 months in Finnish community-dwelling elderly (≥65 years). Baseline serum 25-hydroxyvitamin D (25OHD) concentration was measured by enzymeimmunoassay, and participants (n=518) were divided according to 25OHD to three groups (I <50 nmol/l, II 50-74.9 nmol/l, and III ≥75 nmol/l). PF (maximal isometric extension strength of right and left knee, and time in five-repetition sit-to-stand test (5STS) and 10-m walking test) was measured at baseline and after 12 months. 25OHD deficiency (<50 nmol/l) was found in 20.5% of the participants. During a 12-month follow-up, differences in changes in knee extensor strength of right (p=0.044) and left (p=0.010) lower extremity and in 10-m walking test (p=.040) between the groups were significant. According to further pairwise comparisons these differences were between groups I and III (right knee, p=0.036; left knee, p=0.009; 10-m walk, p=0.044), with the exception of left knee extensor strength in which there were also significant difference between groups I and II (p=0.039). All significant differences in changes were in favour of group II or III. Significant differences in changes in knee extensor strengths maintained after adjustments for group (intervention/control), parathyroid hormone, and baseline level of knee extensor strength. Prospective analyses showed low 25OHD concentrations (<50 nmol/l) to be associated with deterioration in PF during 12 months compared with high 25OHD concentrations (≥75 nmol/l).

In spite of significant disparities in sexual health outcomes for American Indian youth, no studies exist examining the effectiveness of HIV-prevention interventions. Circle of Life is an HIV-prevention intervention specifically developed for American Indian middle-school youth. We describe the rationale, methodology, and baseline results of a longitudinal randomized trial of Circle of Life conducted among American Indian youth aged 11-15 in a reservation community. The innovative design includes two pre-intervention waves to determine patterns of behavior prior to the intervention that might be associated with a differential impact of the intervention on sexual risk. We used one-way analysis of variance and chi-square tests to test for significant differences between randomized group assignment at each baseline wave and generalized estimating equations (GEE) to test significant differences in the rate of change in outcomes by group longitudinally. We present the collaborative and adaptive strategies for consenting, assenting, and data collection methodology in this community. Achieved response rates are comparable to other similar studies. Results from the two baseline waves indicate that few outcomes significantly varied by randomized intervention assignment. Ten percent of youth reported having had sex at Wave 1, rising to 15% at Wave 2. Among those who had had sex, the majority (>70%) reported using a condom at last sex. The project is well positioned to carry out the longitudinal assessments of the intervention to determine the overall impact of the Circle of Life and the differential impact by pre-intervention patterns of behavior across youth.

Background We tested minocycline as an anti-proteinuric adjunct to renin-angiotensin-aldosterone system inhibitors (RAASi) in diabetic nephropathy (DN) and measured urinary biomarkers to evaluate minocycline’s biological effects. Methods Design: Prospective, single center, randomized, placebo-controlled, intention-to-treat pilot trial. Inclusion. Type 2 diabetes/DN; Baseline creatinine clearance > 30 mL/min; proteinuria ≥ 1.0 g/day; Age ≥30 years; BP <150/95 mm Hg; intolerant of/at maximum RAASi dose. Protocol. 3-wk screening; Baseline randomization; Urine and blood measures at months 1, 2, 4, and Month 6 study completion. Urine interleukin-6 (IL-6) and osteoprotegerin were measured in a subset. Primary outcome. Natural log of urine protein/creatinine (ln U P:Cr) ratio at Month 6 vs Baseline. Results 30 patients completed the study. The 15% decline in U P: Cr in minocycline patients (6 month P:Cr ÷ Baseline P:Cr, 0.85 vs. 0.92) was not significant (p = 0.27). Creatinine clearance did not differ in the 2 groups. Urine IL-6:Cr (p = 0.03) and osteoprotegerin/Cr (p = 0.046) decrements were significant. Minocycline modified the relationship between urine IL-6 and proteinuria, suggesting a protective biological effect. Conclusions Although the decline in U P:Cr in minocycline patients was not statistically significant, the significant differences in urine IL-6 and osteoprotegerin suggest that minocycline may confer cytoprotection in patients with DN, providing a rationale for further study.

The present study evaluated and compared the recovery of pectoralis major (PM) and triceps brachii (TB) muscles of trained men after bench press exercise. Eighteen volunteers performed eight sets of bench press exercise to momentary muscle failure and were evaluated for TB and PM peak torque and total work on an isokinetic dynamometer. PM peak torque and total work remained lower than baseline for 72 and 96 h, respectively. TB peak torque was only different from baseline immediately post training, while total work was significantly lower than baseline immediately and 48 h after training. Normalized peak torque values were only different between TB and PM at 48 h after training. Considering the small and nonsignificant difference between the recovery of TB and PM muscles, the results suggest that bench press exercise may promote a similar stress on these muscles.

The increasing prevalence of childhood obesity is a serious public health problem associated with co-morbidities in adulthood, as well as childhood. This study was conducted to identify associations between total sugar intake and sugar intake from different foods (fruit, milk, and sugar-sweetened beverages (SSBs)), and adiposity and continuous metabolic syndrome scores (cMetS) among Korean children and adolescents using cohort data. The study subjects were children (n = 770) who participated in the 4th year (2008) of the Korean Child-Adolescent Cohort Study (KoCAS). Dietary intake data were collected via three-day 24-h food records, and sugar intake was calculated for the total sugar content of foods using our database compiled from various sources. Anthropometric measurements, assessments of body composition, and blood sample analysis were performed at baseline and at follow-up four years later. The cMetS was calculated based on waist circumference, triglycerides, high-density lipoprotein cholesterol, glucose, and mean arterial blood pressure. According to multiple linear regression analysis, there were no significant associations between total sugar intake and adiposity and cMetS. However, higher intake of fruit sugar at baseline was significantly associated with lower body mass index (BMI) z-scores and body fat percentages at baseline (β = -0.10, p = 0.02 and β = -0.78, p < 0.01, respectively). At follow-up, sugar intake from fruit at baseline was still negatively associated with the above outcomes, but only the relationship with BMI z-scores retained statistical significance (β = -0.08, p < 0.05). There was a significant positive relationship between consumption of sugar from SSBs and cMetS at baseline (β = 0.04, p = 0.02), but that relationship was not observed at follow-up (p = 0.83). Differences in consumption sugars from fruit and SSBs might play an important role in the risk of adiposity and metabolic disease in children and adolescents. Our results suggest that strategies for reducing sugar intake need to target particular food groups. Consequently, this information could be of value to obesity- and metabolic disease-prevention strategies.

Objective To evaluate the efficacy of Kivia powder on supporting overall gut health through the relief of the discomfort of occasional constipation. Design Randomized, double-blind, placebo-controlled, parallel-group trial. Interventions The investigational product for this study was Kivia powder (Vital Food Processors Ltd., Auckland, New Zealand), containing the active ingredient Zyactinase™, 5.5 g taken daily for four weeks. Results One hundred thirty-eight subjects reporting occasional constipation were screened and 87 were randomized to placebo (n = 44) and product (n = 43). Bowel movement frequency, as measured by both average daily spontaneous bowel movements (SBM) and complete spontaneous bowel movements (CSBM), were the same in both groups at baseline. There were significant increases in spontaneous bowel movements at week 1 (p = 0.001), week 2 (p = 0.001), week 3 (p = 0.000), and week 4 (p = 0.000) compared to baseline. SBM demonstrated significant differences between the treatment group and the placebo group at week 3 (p = 0.000), and week 4 (p = 0.020). The treatment group demonstrated a significantly higher rate of SBM at week 3 (p = 000) and from baseline to week 4 (p = 0.019). Significant increases in complete spontaneous bowel movements were observed at week 1 (p = 0.000), week 2 (p = 0.000), week 3 (p = 0.000), and week 4 (p = 0.000) compared to baseline. Moreover, CSBM was significantly higher for the treatment group compared to placebo at week 2 (p = 0.001). The change in average daily CSBM from baseline to week 2 was significantly higher in the treatment group than in the placebo group (p = 0.004). Abdominal discomfort or pain demonstrated significant differences between groups at week 1 (p = 0.044) and week 3 (p = 0.026). Flatulence was significantly lower for active group compared to placebo at week 2 (p = 0.047) and week 3 (p = 0.023). The number of bowel movements associated with urgency was significantly lower in the treatment group compared to the placebo group at week 3 (p = 0.048). In addition, it was decreased from baseline to week 1 (p = 0.040) and from baseline to week 3 (p = 0.024) in the treatment group, while the placebo group did not report any reductions in bowel urgency. Bowel movements in the treatment arm were significantly smoother and softer by week 2 (p = 0.020) and week 3 (p = 0.041). Conclusions Treatment with Kivia powder, an extract of kiwifruit containing Zyactinase™, for four weeks was well tolerated and more effective than placebo in gently enhancing bowel movement frequency and reducing abdominal pain and flatulence in subjects with occasional constipation.

Patient navigation is a promising intervention to ameliorate cancer health disparities. This study objective was to measure patient navigation effects on cancer-specific quality of life (QOL) among patients with newly diagnosed cancer. A randomized controlled trial of patient navigation was conducted in Rochester, NY. Patients with breast cancer and colorectal cancer were randomly assigned to receive a patient navigation intervention or usual care. QOL was measured at baseline and four subsequent time points, using the validated Functional Assessment of Cancer Therapy (FACT-B, FACT-C) instruments. Among 319 randomized patients (165 patient navigation, 154 control), median age was 57 years and 32.5% were from minority race/ethnicity groups. Patient navigation and control groups were comparable on baseline factors, except home ownership versus renting (more home ownership among controls, P = 0.05) and race (more whites among controls, P = 0.05). Total and subscale FACT scores did not differ between groups when analyzed as a change from baseline to 3 months, or at various time points. The emotional well-being subscale change from baseline approached significance (better change among patient navigation group, P = 0.05). Time trends of QOL measures did not differ significantly between groups. Adjustment for baseline patient factors did not reveal a benefit of patient navigation on QOL. In this randomized trial of patient navigation, there was no statistically significant effect on disease-specific QOL. These results suggest that patient navigation may not affect QOL during cancer treatment, that social/medical support are adequate in this study's setting, or that the trial failed to target patients likely to experience QOL benefit from patient navigation. 2012 AACR

The present study sought to examine the influence of physical activity on quality of life and negative mood in a sample of Black breast cancer survivors to determine if physical activity (dichotomized) predicted mean differences in negative mood and quality of life in this population. Study participants include 114 women diagnosed with breast cancer (any stage of disease, any type of breast cancer) recruited to participate in an adaptive cognitive-behavioral stress management intervention. The mean body mass index of the sample at baseline was 31.39 (standard deviation = 7.17). A multivariate analysis of covariance (MANCOVA) was conducted to determine if baseline physical activity predicted mean differences in negative mood and quality of life at baseline and at follow ups while controlling for relevant covariates. A one-way MANCOVA revealed a significant multivariate effect by physical activity group for the combined dependent variables at Time 2 (post 10-week intervention), p = .039. The second one-way MANCOVA revealed a significant multivariate effect at Time 3 (6 months after Time 2), p = .034. Specifically, Black breast cancer survivors who engaged in physical activity experienced significantly lower negative mood and higher social/family well-being at Time 2 and higher spiritual and functional well-being at Times 2 and 3. Results show that baseline physical activity served protective functions for breast cancer survivors over time. Developing culturally relevant physical activity interventions specifically for Black breast cancer survivors may prove vital to improving quality of life and mood in this population.

To test whether an image-processing algorithm can aid in visualization of mesial temporal sclerosis on magnetic resonance imaging by selectively increasing contrast-to-noise ratio (CNR) between abnormal hippocampus and normal brain. In this Institutional Review Board-approved and Health Insurance Portability and Accountability Act-compliant study, baseline coronal fluid-attenuated inversion recovery images of 18 adults (10 females, eight males; mean age 41.2 years) with proven mesial temporal sclerosis were processed using a custom algorithm to produce corresponding enhanced images. Average (Hmean) and maximum (Hmax) CNR for abnormal hippocampus were calculated relative to normal ipsilateral white matter. CNR values for normal gray matter (GM) were similarly calculated using ipsilateral cingulate gyrus as the internal control. To evaluate effect of image processing on visual conspicuity of hippocampal signal alteration, a neuroradiologist masked to the side of hippocampal abnormality rated signal intensity (SI) of hippocampi on baseline and enhanced images using a five-point scale (definitely abnormal to definitely normal). Differences in Hmean, Hmax, GM, and SI ratings for abnormal hippocampi on baseline and enhanced images were assessed for statistical significance. Both Hmean and Hmax were significantly higher in enhanced images as compared to baseline images (p < 0.0001 for both). There was no significant difference in the GM between baseline and enhanced images (p = 0.9375). SI ratings showed a more confident identification of abnormality on enhanced images (p = 0.0001). Image-processing resulted in increased CNR of abnormal hippocampus without affecting the CNR of normal gray matter. This selective increase in conspicuity of abnormal hippocampus was associated with more confident identification of hippocampal signal alteration. Copyright © 2018 Academic Radiology.

Background. Rifaximin, a nonabsorbable antibiotic that decreases lipopolysaccharide (LPS) in cirrhotics, may decrease the elevated levels of microbial translocation, T-cell activation and inflammation in human immunodeficiency virus (HIV)-positive immune nonresponders to antiretroviral therapy (ART). Methods. HIV-positive adults receiving ART for ≥96 weeks with undetectable viremia for ≥48 weeks and CD4+ T-cell counts <350 cells/mm3 were randomized 2:1 to rifaximin versus no study treatment for 4 weeks. T-cell activation, LPS, and soluble CD14 were measured at baseline and at weeks 2, 4, and 8. Wilcoxon rank sum tests compared changes between arms. Results. Compared with no study treatment (n = 22), rifaximin (n = 43) use was associated with a significant difference between study arms in the change from baseline to week 4 for CD8+T-cell activation (median change, 0.0% with rifaximin vs +0.6% with no treatment; P = .03). This difference was driven by an increase in the no-study-treatment arm because there was no significant change within the rifaximin arm. Similarly, although there were significant differences between study arms in change from baseline to week 2 for LPS and soluble CD14, there were no significant changes within the rifaximin arm. Conclusions. In immune nonresponders to ART, rifaximin minimally affected microbial translocation and CD8+T-cell activation. Trial registration number. NCT01466595. PMID:25214516

Baseline element concentrations are given for Spanish moss (Tillandsia usneoides), loblolly pine (Pinus taeda), and associated soils. Baseline and variability data for ash, Al, Ba, C, Ca, Cd, Ce, Co, Cr, Cu, Fe, K, La, Li, Mg, Mn, Na, Nb, Nd, Ni, P, Pb, S, Sc, Sr, Th, Ti, V, Y, and Zn are reported; however, not all variables are reported for all media because, in some media, certain elements were below the analytical detection limit. Spatial variation in element concentration among and within 0.5 km grid cells are given for each of the media. In general, only a few elements in Spanish moss showed statistically significant landscape patterns, whereas several elements in loblolly pine and in soils exhibited differences among sampling grids. Significant differences in the concentration of three elements in Spanish moss and eight elements (including total S) in loblolly pine were observed between two sampling dates (November and June); however, the absolute amount of these differences was small. Except for perhaps Ni and Pb concentrations in Spanish moss, element levels in all sample media exhibited ranges that indicate natural rather than anthropogenic additions of trace elements.

Aims. To compare the baseline characteristics of a population-based cohort of patients with ankylosing spondylitis (AS) commencing biological therapy to the reported characteristics of bDMARD randomised controlled trials (RCTs) participants. Methods. Descriptive analysis of AS participants in the Australian Rheumatology Association Database (ARAD) who were commencing bDMARD therapy. Results. Up to December 2008, 389 patients with AS were enrolled in ARAD. 354 (91.0%) had taken bDMARDs at some time, and 198 (55.9%) completed their entry questionnaire prior to or within 6 months of commencing bDMARDs. 131 (66.1%) had at least one comorbid condition, and 24 (6.8%) had a previous malignancy (15 nonmelanoma skin, 4 melanoma, 2 prostate, 1 breast, cervix, and bowel). Compared with RCT participants, ARAD participants were older, had longer disease duration and higher baseline disease activity. Conclusions. AS patients commencing bDMARDs in routine care are significantly different to RCT participants and have significant baseline comorbidities. PMID:20107564

Severity of illness scores rest on the assumption that patients have normal physiologic values at baseline and that patients with similar severity of illness scores have the same degree of deviation from their usual state. Prior studies have reported differences in baseline physiology, including laboratory markers, between obese and normal weight individuals, but these differences have not been analyzed in the ICU. We compared deviation from baseline of pertinent ICU laboratory test results between obese and normal weight patients, adjusted for the severity of illness. Retrospective cohort study in a large ICU database. Tertiary teaching hospital. Obese and normal weight patients who had laboratory results documented between 3 days and 1 year prior to hospital admission. None. Seven hundred sixty-nine normal weight patients were compared with 1,258 obese patients. After adjusting for the severity of illness score, age, comorbidity index, baseline laboratory result, and ICU type, the following deviations were found to be statistically significant: WBC 0.80 (95% CI, 0.27-1.33) × 10/L; p = 0.003; log (blood urea nitrogen) 0.01 (95% CI, 0.00-0.02); p = 0.014; log (creatinine) 0.03 (95% CI, 0.02-0.05), p < 0.001; with all deviations higher in obese patients. A logistic regression analysis suggested that after adjusting for age and severity of illness at least one of these deviations had a statistically significant effect on hospital mortality (p = 0.009). Among patients with the same severity of illness score, we detected clinically small but significant deviations in WBC, creatinine, and blood urea nitrogen from baseline in obese compared with normal weight patients. These small deviations are likely to be increasingly important as bigger data are analyzed in increasingly precise ways. Recognition of the extent to which all critically ill patients may deviate from their own baseline may improve the objectivity, precision, and generalizability of ICU mortality prediction and severity adjustment models.

Background: Limited literature exists regarding the influence of rotator cuff tear morphology on patient outcomes. Purpose: To determine the effect of rotator cuff tear pattern (crescent, U-shape, L-shape) on patient-reported outcomes after rotator cuff repair. Study Design: Cohort study; Level of evidence, 3. Methods: Patients undergoing arthroscopic repair of known full-thickness rotator cuff tears were observed prospectively at regular intervals from baseline to 1 year. The tear pattern was classified at the time of surgery as crescent, U-shaped, or L-shaped. Primary outcome measures were the Western Ontario Rotator Cuff Index (WORC), the American Shoulder and Elbow Surgeons (ASES), and a visual analog scale (VAS) for pain. The tear pattern was evaluated as the primary predictor while controlling for variables known to affect rotator cuff outcomes. Mixed-methods regression and analysis of variance (ANOVA) were used to examine the effects of tear morphology on patient-reported outcomes after surgical repair from baseline to 1 year. Results: A total of 82 patients were included in the study (53 male, 29 female; mean age, 58 years [range, 41-75 years]). A crescent shape was the most common tear pattern (54%), followed by U-shaped (25%) and L-shaped tears (21%). There were no significant differences in outcome scores between the 3 groups at baseline. All 3 groups showed statistically significant improvement from baseline to 1 year, but analysis failed to show any predictive effect in the change in outcome scores from baseline to 1 year for the WORC, ASES, or VAS when tear pattern was the primary predictor. Further ANOVA also failed to show any significant difference in the change in outcome scores from baseline to 1 year for the WORC (P = .96), ASES (P = .71), or VAS (P = .86). Conclusion: Rotator cuff tear pattern is not a predictor of functional outcomes after arthroscopic rotator cuff repair. PMID:29623283

Cardio-metabolic syndrome (CMS) is a highly prevalent condition. There is an urgent need to identify effective and integrated multi-disciplinary approaches that can reduce risk factors for CMS. Sixty-two patients with a history of CMS were randomized 1:1 into two groups: a standard information -only group (control), or a self-regulated lifestyle waist circumference (patient-centered cognitive behavioral therapy) intervention group. A pretest and posttest, controlled, experimental design was used. Outcomes were measured at the baseline (week 0) and at the end of intervention (week 12). Comparisons were drawn between groups and over time. The mean (standard deviation) age of the subjects was 48.6 (5.8) years ranging from 32 to 63, and 56.9% of the participants were female. Both groups showed no significant differences in Demographic variables and the metabolic syndrome indicators at baseline. While the control group only showed modest improvement after 12 weeks, compared to baseline, the intervention group demonstrated significant improvement from baseline. This study controlled for patients' demographics and baseline characteristics when assessing the effects of intervention. After adjusting for age, education and baseline level, the experimental group and the control group were statistically significant different in the following post-treatment outcomes: WC (F = 35.96, P < 0.001), TG (F = 18.93, P < 0.001), RSBP (F = 33.89, P < 0.001) and SF-36(F = 157.93, P < 0.001). The results showed patients' age and education were not strong predictors of patients' outcome (including WC, TG, RSBP and SF-36). Lifestyle intervention on patient-centered cognitive behavioral therapy can improve the physical and mental health conditions among individuals reporting a history of cardio-metabolic syndrome, and possibly provided preliminary benefits for the treatment of CMS.

Using a spherically symmetric, self-gravitating, linear viscoelastic Earth model, we predict present-day three-dimensional surface deformation rates and baseline evolutions arising as a consequence of the late Pleistocene glacial cycles. In general, we use realistic models for the space-time geometry of the final late Pleistocene deglaciation event and incorporate a gravitationally self-consistent ocean meltwater redistribution. The predictions of horizontal velocity presented differ significantly, in both their amplitude and their spatial variation, from those presented in earlier analysis of others which adopted simplified models of both the late Pleistocene ice history and the Earth rheology. An important characteristic of our predicted velocity fields is that the melting of the Laurentide ice sheet over Canada is capable of contributing appreciably to the adjustment in Europe. The sensitivity of the predictions to variations in mantle rheology is investigated by considering a number of different Earth models, and by computing appropriate Frechet kernels. These calculations suggest that the sensitivity of the deformations to the Earth's rheology is significant and strongly dependent on the location of the site relative to the ancient ice sheet. The effects on the predictions of three-dimensional deformation rates of altering the ice history or adopting approximate models for the ocean meltwater redistribution have also been considered and found to be important (the former especially so). Finally, for a suite of Earth models we provide predictions of the velocity of a number of baselines in North America and Europe. We find that, in general, both radial and tangential motions contribute significantly to baseline length changes, and that these contributions are a strong function of the Earth model. We have, furthermore, found a set of Earth models which, together with the ICE-3G deglaciation chronology, produce predictions of baseline length changes that are consistent with very long baseline interferometry measurements of baselines within Europe.

Hypoalbuminemia, a frailty criterion, belongs to a group of co-morbidities not captured as a traditional risk factor. We assessed its prognostic value in patients who underwent transcatheter aortic valve implantation (TAVI). The study included 1,215 consecutive patients from the Optimized Catheter Valvular Intervention -TAVI Japanese multicenter registry. Hypoalbuminemia was defined as serum albumin level <3.5 g/dl. Baseline characteristics, procedural outcomes, and all-cause, cardiovascular and noncardiovascular mortality rates after TAVI were compared between patients with albumin level <3.5 g/dl (hypo[h]-ALB group, n = 284) and those with albumin level >3.5 g/dl (nonhypo[nh]-ALB group, n = 931). Several baseline characteristics differed significantly between both groups, including age (85.1 ± 5.1 vs 84.2 ± 4.9 years, p = 0.012), ejection fraction (58.5 ± 14.3% vs 62.9 ± 12.4%, p <0.001), baseline kidney function, or liver disease. The 30-day mortality rate in all patients showed significant differences between the 2 groups (3.9% vs 1.3%, p = 0.005). During a mean follow-up of 330 days, cumulative all-cause, cardiovascular, and noncardiovascular mortality rates were significantly higher in the hALB group than in the nhALB group (log-rank test, p <0.001, p = 0.0021, and p <0.001, respectively). The groups were also analyzed using a propensity matching model for adjusting the baseline differences. The analysis revealed that the poorer prognosis of the hALB group in terms of cumulative all-cause and noncardiovascular mortality was retained (p = 0.038, and p = 0.0068, respectively); however, differences in cardiovascular mortality rates in the 2 groups were attenuated (p = 0.93). In conclusion, hypoalbuminemia was associated with poor prognosis, highlighted by the increase in noncardiovascular mortality. Baseline albumin level could be a useful marker for risk stratification before TAVI. Copyright © 2016 Elsevier Inc. All rights reserved.

Physicians must participate in end-of-life discussions, but they understand poorly their patients' end-of-life values and preferences. A better understanding of these preferences and the effect of baseline attitudes will improve end-of-life discussions. To determine how baseline attitudes toward quality vs quantity of life affect end-of-life resource allocation. Otolaryngology-head and neck surgery (OHNS) physicians were recruited to use a validated online tool to create a Medicare health plan for advanced cancer patients. During the exercise, participants allocated a limited pool of resources among 15 benefit categories. These data were compared with preliminary data from patients with cancer and their caregivers obtained from a separate study using the same tool. Attitudes toward quality vs quantity of life were assessed for both physicians and patients and caregivers. Participation in online assessment exercise. Medicare resource allocation. Of 9120 OHNS physicians e-mailed, 767 participated. Data collected from this group were compared with data collected from 146 patients and 114 caregivers. Compared with patients and caregivers, OHNS physician allocations differed significantly in all 15 benefit categories except home care. When stratified by answers to 3 questions about baseline attitudes toward quality vs quantity of life, there were 3 categories in which allocations of patients and caregivers differed significantly from the group with the opposite attitude for at least 2 questions: other medical care (question 1, P < .001; question 2, P = .005), palliative care (question 1, P = .008; question 2, P = .006; question 3, P = .009), and treatment for cancer (questions 1 and 2, P < .001). In contrast, physician preferences showed significant differences in only 1, nonmatching category for each attitude question: cash (question 1, P = .02), drugs (question 2, P = .03), and home care (question 3, P = .048). Patients with cancer and their caregivers have different preferences from physicians. These preferences are, for these patients and their caregivers, affected by their baseline health attitudes, but physician preferences are not. Understanding the effect of baseline attitudes is important for effective end-of-life discussions.

This study investigated the effect of Vibram FiveFingers Bikila minimalist shoes on intrinsic foot musculature. We hypothesized that a gradual transition into minimalist shoes will increase the thickness of the abductor hallucis muscle. Forty-one individuals were divided into four groups: control (traditional shod) (n = 9), restricted walking in Vibram FiveFingers (n = 11), running in Vibram FiveFingers (n = 10), and unlimited walking in Vibram FiveFingers (n = 11). At baseline, 12 weeks, and 24 weeks, the thickness of the abductor hallucis muscle was determined using ultrasound. Statistical analysis was performed to determine the significance of differences in muscle thickness at the three different time points. The mean thickness of the abductor hallucis muscle at 24 weeks was significantly greater than that at baseline for the restricted walking (P = .005) and running (P < .001) groups. In the unlimited walking group, the mean thickness of the muscle at 12 weeks was significantly greater than that at baseline (P < .05) but not at 24 weeks. There were no significant differences in muscle thickness among the three time points for the control group (P = .432). This study demonstrated that wearing Vibram FiveFinger Bikila footwear over a controlled period of time, an unlimited amount of time, as well as transitioning runners over a 6-month period of time using the 10% philosophy for increasing mileage, significantly increases intrinsic muscle thickness of the abductor hallucis. The abductor hallucis muscle aids in support of the medial longitudinal arch, and an increase in this muscle thickness may help reduce running-related injuries thought to arise from arch weakness.

Individuals with bulimia nervosa (BN) often report co-morbid symptoms of non suicidal self-injury (NSSI). This study examined the influence of (lack of) perseverance, (lack of) premeditation, sensation seeking, and negative urgency (the tendency to act rashly when experiencing negative affect) on these two behavior patterns. We hypothesized that negative urgency influences vulnerability to multiple maladaptive behavior patterns, thus influencing the co-occurrence of NSSI and BN symptoms. 489 young adult women completed baseline assessments, and 209 completed an eight month follow-up assessment. Structural equation modeling was used to examine the influence of four personality pathways to impulsive behavior simultaneously on both behaviors at baseline, and the incremental predictive utility of traits on both behaviors at eight month follow up. Additionally, we examined the influence of NSSI at baseline on symptoms of BN at follow up, and symptoms of BN at baseline on NSSI at follow up. Negative urgency accounted for significant variance in NSSI and eating pathology. Baseline (lack of) perseverance contributed significantly to binge eating frequency at follow-up, when accounting for baseline symptoms. NSSI at baseline was associated with increased purging at follow-up. Individual differences in impulsivity appear to influence both NSSI and eating pathology. Copyright © 2012 Elsevier Ltd.

Previous studies have reported a meal-induced rise in hepatic glycogen stores from baseline levels following a fast and it is generally assumed that glycogen levels rise steadily following meals throughout the day. However, measurements are normally taken in conditions that are not typical of the Western breakfast, which is relatively carbohydrate rich with a lower calorific content than most experimental test meals. As such, little is known about the normal metabolic response to a realistic, low calorie morning meal. Therefore, the aim of this pilot study was to evaluate the effects of a low dose oral glucose intake on hepatic glycogen levels following an overnight fast in healthy subjects. Glycogen levels were monitored in vivo using (13)C Magnetic Resonance Spectroscopy at baseline and hourly for 4 hours following either a 50 g glucose drink (773 kJ) or a control drink (0 kJ) given over two different visits. During the control visit hepatic glycogen levels decreased throughout the experiment with statistically significant decreases from baseline at 190 minutes (P < 0.05) and 250 minutes (P < 0.05). By contrast, the low dose glucose intake maintained glycogen concentrations with no significant decrease from baseline over 4 hours. A comparison between visits revealed that mean glycogen concentrations were significantly greater during the glucose visit (control visit, AUC = 218 ± 39 mol L(-1) min(-1); glucose visit, AUC = 305 ± 49 mol L(-1) min(-1); P < 0.05). Liver volume decreased significantly from baseline at 180 minutes (P < 0.05) post consumption in both groups, with no significant difference found between visits. Gastric content volumes were significantly higher for the glucose visit immediately following consumption (P < 0.001) and at 60 minutes (P = 0.007) indicating slower gastric emptying for the glucose compared with the control. In conclusion, following an overnight fast, a low dose oral glucose challenge prevents a reduction in hepatic glycogen content but does not increase it above fasted levels.

This study compared the effect of a strength training session performed at different exercise orders and rest intervals on blood pressure and heart rate variability (HRV). Fifteen trained men performed different upper body exercise sequences [large to small muscle mass (SEQA) and small to large muscle mass (SEQB)] in randomized order with rest intervals between sets and exercises of 40 or 90 seconds. Fifteen repetition maximum loads were tested to control the training intensity and the total volume load. The results showed, significant reductions for systolic blood pressure (SBP) for all sequences compared to baseline and, post-exercise: SEQA90 at 20, 30, 40, 50 and 60 minutes; SEQA40 and SEQB40 at 20 minutes and SEQB90 at 10, 20, 30, 40, 50 and 60 minutes. For diastolic blood pressure (DBP), significant reductions were found for three sequences compared to baseline and, post-exercise: SEQA90 and SEQA40 at 50 and 60 minutes; SEQB40 at 10, 30 and 60 minutes. For HRV, there were significant differences in frequency domain for all sequences compared to baseline. In conclusion, when performing upper body strength training sessions, it is suggested that 90 second rest intervals between sets and exercises promotes a post-exercise hypotensive response in SBP. The 40 second rest interval between sets and exercises was associated with greater cardiac stress, and might be contraindicated when working with individuals that exhibit symptoms of cardiovascular disease.

Preservation of locomotor activity in multiple sclerosis (MS) patients is of utmost importance. Robotic-assisted body weight-supported treadmill training is a promising method to improve gait functions in neurologically impaired patients, although its effectiveness in MS patients is still unknown. To compare the effectiveness of robot-assisted gait training (RAGT) with that of conventional walking treatment (CWT) on gait and generalized functions in a group of stable MS patients. A prospective randomized controlled trial of 12 sessions of RAGT or CWT in MS patients of EDSS score 5-7. Primary outcome measures were gait parameters and the secondary outcomes were functional and quality of life parameters. All tests were performed at baseline, 3 and 6 months post-treatment by a blinded rater. Fifteen and 17 patients were randomly allocated to RAGT and CWT, respectively. Both groups were comparable at baseline in all parameters. As compared with baseline, although some gait parameters improved significantly following the treatment at each time point there was no difference between the groups. Both FIM and EDSS scores improved significantly post-treatment with no difference between the groups. At 6 months, most gait and functional parameters had returned to baseline. Robot-assisted gait training is feasible and safe and may be an effective additional therapeutic option in MS patients with severe walking disabilities.
Effect of Consuming Tea with Stevia on Salivary pH - An In Vivo Randomised Controlled Trial.
Pallepati, Akhil; Yavagal, Puja; Veeresh, D J
To assess the effect of consuming tea with stevia on salivary pH. This randomised controlled trial employed a Latin square design. Twenty-four male students aged 20-23 years were randomly allocated to 4 different groups, 3 experimental with tea sweetened by sucrose, jaggery or stevia, and one unsweetened control. Salivary pH assessments were performed at baseline and 1 min, 20 and 60 min after consumption of the respective tea. One-way ANOVA and repeated measures ANOVA followed by Tukey's post-hoc tests were employed to analyse the data. One minute after tea consumption, the salivary pH of the sucrose group significantly decreased compared to the stevia group (p = 0.01). There was a significant difference between baseline mean salivary pH and post-interventional mean salivary pH values at all time intervals in the tea + sucrose, tea + jaggery, and plain tea groups (p < 0.01). One hour after consumption of tea, the salivary pH values reached the baseline pH in stevia and plain tea groups, but it remained lower in the sucrose and jaggery groups. The results of the present study, in which the salivary pH values returned to baseline pH 1 h after drinking stevia-sweetened tea, suggest stevia's potential as a non-cariogenic sweetener.

The purpose of this study was to evaluate the 12-month clinical performance of glass ionomer restorations in teeth with MIH. First permanent molars affected by MIH (48) were restored with glass ionomer cement (GIC) and evaluated at baseline, at 6 and at 12 months, by assessing tooth enamel breakdown, GIC breakdown and caries lesion associations. The data were analyzed using the chi-square test and actuarial survival analysis. The likelihood of a restored tooth remaining unchanged at the end of 12 months was 78%. No statistically significant difference was observed in the association between increased MIH severity and caries at baseline (p > 0.05) for a 6-month period, or between increased MIH severity and previous unsatisfactory treatment at baseline (p > 0.05) for both a 6- and 12-month period. A statistically significant difference was observed in the association between increased MIH severity and extension of the restoration, involving 2 or more surfaces (p < 0.05) at both periods, and between increased MIH severity and caries at baseline (p < 0.05) at a 12-month period. Because the likelihood of maintaining the tooth structures with GIC restorations is high, invasive treatment should be postponed until the child is sufficiently mature to cooperate with the treatment, mainly of teeth affected on just one face.

In the present study, homovanillic acid in plasma (pHVA) and benzodiazepine receptors (3H-PK11195 binding) in neutrophil membranes were determined in blood obtained from cocaine-dependent (DSM-III-R) adult male inpatients at baseline-(within 72 hr of last cocaine use) and after 3 weeks of cocaine abstinence, and normal controls. The mean (+/- SEM) pHVA at baseline (10.3 ng/ml +/- 1.1) was similar to normals and did not change after 3 weeks of cocaine abstinence. Similarly, the binding indices of benzodiazepine receptors in cocaine-dependent subjects as a group were not significantly different than in normal controls. In 10 cocaine-dependent subjects, however, where both blood samples were available, the number of 3H-PK11195 binding sites was significantly (p < 0.05) decreased after 3 weeks of cocaine abstinence (mean +/- sem: Bmax = 6371 +/- 657 fmol/mg protein) compared with baseline (Bmax = 7553 +/- 925 fmol/mg protein), although there were no differences in the binding affinity (mean +/- sem: KD = 8.6 +/- 1.2 nmol/L after 3 weeks of abstinence compared with 8.1 +/- 1.0 nmol/L at baseline). These preliminary results suggest that peripheral benzodiazepine receptors may play an important role in the pathophysiology of cocaine withdrawal in cocaine-dependent human subjects.

This quasi-experimental study assessed the effects of new workplace showers on physical activity behaviors in a sample of downtown employees in Austin, TX. The study design was quasi-experimental with 2 comparison groups. Data were collected via internet-based surveys before and 4 months after shower installation at 1 worksite. Differences across study groups in the ranks of change in past-week minutes of physical activity from baseline to follow-up were assessed. Adjusted odds ratios and 95% confidence intervals for reporting an increase of ≥10 min past-week physical activity and workday physical activity among those with new showers and existing showers relative to those with no showers were also assessed. No significant differences in changes in physical activity from baseline to follow-up across study groups were found. One-quarter of participants with new workplace showers and 46.9% of those with existing workplace showers at baseline reported ever using the showers. This prospective study did not find significant changes in employee physical activity 4 months after installation of worksite showers. Worksite shower users were highly active at baseline, suggesting a possible early adopter effect, with potential for diffusion. Future studies may benefit from longer exposure times and larger samples.

The study aimed to quantify the color regression of enamel (E), dentine (D), and combined enamel-dentine (ED) of differently bleached ED specimens over a period of 12 months in vitro. Two ED samples were obtained from the labial surfaces of bovine teeth and prepared to a standardized thickness with the enamel and dentine layer each 1 mm. The ED samples were distributed on four groups (each n = 80), in which the different bleaching products were applied on enamel (1, Whitestrips; 2, Illuminé 15%; 3, Opalescence Xtra Boost) or dentine surfaces (4, mixture of sodium perborate/distilled water). Eighty ED samples were not bleached (control). Color (L*a*b*) of ED was assessed at baseline, subsequently after bleaching and at 3, 6, and 12 months of storage after bleaching (each 20 samples/group). E and D samples were prepared by removing the dentine or enamel layer of ED samples to allow for separate color analysis. Bleaching resulted in a significant color change (Delta E) of ED specimens. Within the observation period, Delta L but not Delta b declined to baseline. L* values of E and D samples also declined and were not significantly different from control samples after 12 months, while b* values did not decrease to baseline. Generally, no differences between the bleaching agents could be observed. Color change of enamel, dentine, and combined ED of in vitro bleached tooth samples is not stable over time with regard to lightness. However, yellowness did not return to baseline within 1 year.

The aim of this study was to investigate healthcare utilization patterns over a six-year period among older people (60+), classified as dependent/independent in Activities of Daily Living (ADL) and/or at/not at risk of depression and to identify healthcare utilization predictors. A sample (n=1402) comprising ten age cohorts aged between 60 and 96 years was drawn from the Swedish National study on Aging and Care (SNAC). Baseline data were collected between 2001 and 2003. Number and length of hospital stays were collected for six years after baseline year. Group differences and mean changes over time were investigated. Healthcare utilization predictors were explored using multiple linear regression analysis. The results revealed that 21-24% had at least one hospital stay in the six years after baseline, 29-37% among ADL dependent subjects and 24-33% among those at risk of depression. There was a significant increase of hospital stays in all groups over time. ADL-dependent subjects and those at risk of depression had significant more hospital stays, except for those at/not at risk of depression in years 2, 4 and 5. The healthcare utilization predictors 5-6 years after baseline were mainly age, previous healthcare utilization and various symptoms and, in 1-2 and 3-4 years after baseline, age, various diagnostic groups and various physical variables. Thus healthcare utilization patterns seem to be similar for the different groups, but it is difficult to find universal predictors. This suggests that different variables should be considered, including both ADL and psychosocial variables, when trying to identify future healthcare users. Copyright © 2012 Elsevier Ireland Ltd.

Effect of fructose and sucralose on flow-mediated vasodilatation in healthy, white European males.
Memon, Muhammad Qasim; Simpson, Elizabeth Jane; Macdonald, Ian Andrew
2014-07-01
To assess how acute consumption of fructose affects flow-mediated dilatation in brachial artery. The randomised cross-over study was conducted at the University of Nottingham's Medical School, Nottingham, United Kingdom in July 2009. Ten healthy, white European males visited the laboratory twice, on separate mornings. On each visit, the volunteers consumed water (3 ml/kg bodyweight) and rested semi-supine on the bed. After 30 minutes, baseline diastolic brachial artery diameter and blood velocity was measured. At 60 minutes, blood velocity and five scans of brachial artery diameter were recorded before a blood pressure cuff was inflated on the forearm for 5 minutes and at 50-60-70-80 and 90 sec after cuff deflation. Fifteen minutes later, the volunteers consumed 500 ml of test-drink containing either fructose (0.75 g/kg bodyweight) or sucralose (sweetness-matched with fructose drink); 45 minutes later, baseline and flow-mediated dilatation was re-measured. Pre-drink and post-drink baseline values were similar on two occasions (p > 0.05). Brachial artery diameter increased (p < 0.05) by 7 +/- 3% pre-fructose and by 6.9 +/- 3% above baseline values post-fructose with no significant difference in these responses (p < 0.15). It increased (p < 0.05) by 5.9 +/- 3% above baseline before and by 6.7 +/- 2% (p < 0.01) after sucralose; a significant difference was noted in these flow-mediated dilatation responses (p < 0.02). Responses before and after sucralose were not different from those before and after fructose (p < 0.294). Acute ingestion of fructose or sucralose had no effect on flow-mediated dilatation measured at brachial artery.

Critical thinking is essential to nursing practice. This study examined differences in the critical thinking dispositions of registered nurses (RNs) in a nursing fellowship program. Control and experimental groups were used to compare differences in scores on the California Critical Thinking Disposition Inventory (CCTDI) of RNs at three points during a fellowship program: baseline, week 7, and month 5. The control group consisted of RNs who received no education in critical thinking. The experimental group received education in critical thinking using simulated scenarios and reflective journaling. CCTDI scores examined with analysis of variance showed no significant difference within groups over time or between groups. The baseline scores of the experimental group were slightly higher than those of the control group. Chi-square analysis of demographic variables between the two groups showed no significant differences. Critical thinking dispositions are a combination of attitudes, values, and beliefs that make up one's personality based on life experience. Lack of statistical significance using a quantitative approach did not capture the development of the critical thinking dispositions of participants. A secondary qualitative analysis of journal entries is being conducted. Copyright 2013, SLACK Incorporated.

This study compares men and women with alcohol use disorders on levels and trajectories of spirituality and religiousness over 30 months while controlling for critical covariates. Men (n=92) and women (n=65) entering abstinence-based treatment were assessed for drinking behavior, spirituality, and psychosocial variables in a longitudinal panel study. Multiple regression tested for baseline differences and multi-level models tested for differences from baseline to 6 months (early recovery) and from 6 to 30 months (later recovery) in seven dimensions of spirituality/religiousness. Between baseline and 6 months, women had higher scores than men for forgiveness of others and lower scores than men for negative religious coping. Between 6 and 30 months, the acceleration of positive change in self forgiveness was significantly greater for women than men. Differences in negative religious coping and forgiveness might relate to differences in shame and guilt and their resolution by gender. Future research should examine whether gender differences in spirituality serve as an asset to women as they pursue addiction recovery. PMID:29250216

This prospective, randomized, split-mouth clinical trial evaluated the clinical performance of conventional glass ionomer cement (GIC; Riva Self-Cure, SDI), supplied in capsules or in powder/liquid kits and placed in Class I cavities in permanent molars by the Atraumatic Restorative Treatment (ART) approach. A total of 80 restorations were randomly placed in 40 patients aged 11-15 years. Each patient received one restoration with each type of GIC. The restorations were evaluated after periods of 15 days (baseline), 6 months, and 1 year, according to ART criteria. Wilcoxon matched pairs, multivariate logistic regression, and Gehan-Wilcoxon tests were used for statistical analysis. Patients were evaluated after 15 days (n=40), 6 months (n=34), and 1 year (n=29). Encapsulated GICs showed significantly superior clinical performance compared with hand-mixed GICs at baseline (p=0.017), 6 months (p=0.001), and 1 year (p=0.026). For hand-mixed GIC, a statistically significant difference was only observed over the period of baseline to 1 year (p=0.001). Encapsulated GIC presented statistically significant differences for the following periods: 6 months to 1 year (p=0.028) and baseline to 1 year (p=0.002). Encapsulated GIC presented superior cumulative survival rate than hand-mixed GIC over one year. Importantly, both GICs exhibited decreased survival over time. Encapsulated GIC promoted better ART performance, with an annual failure rate of 24%; in contrast, hand-mixed GIC demonstrated a failure rate of 42%.

The amygdala's role in threat perception suggests that increased activation of this region may be related to paranoid ideation. However, investigations of amygdala function in paranoid individuals with schizophrenia, compared with both healthy individuals and nonparanoid individuals with schizophrenia, have consistently reported reduced task-related activation. The reliance of blood-oxygen-level-dependent functional MRI on a contrast between events and baseline, and the inability to quantitatively measure this baseline, may account for these counterintuitive findings. The present study tested for differences in baseline levels of amygdala activity in paranoid and nonparanoid individuals with schizophrenia using arterial spin labeling perfusion MRI. Resting cerebral blood flow (CBF) and task-related activation of the amygdala were measured in 25 healthy individuals, 16 individuals with schizophrenia who were actively paranoid at the time of scanning, and 16 individuals with schizophrenia who were not paranoid. Analysis of relative CBF values extracted from the amygdala bilaterally revealed significantly increased activity in the left amygdala in paranoid patient volunteers compared with healthy comparison subjects and nonparanoid patient volunteers. Increased CBF was also evident in the right amygdala but did not reach the level of statistical significance. Paranoid volunteers also showed significantly decreased task-related activation of the amygdala compared with the two other groups. These findings suggest that amygdala hyperactivation may underlie paranoia in schizophrenia. Additionally, the reported differences between paranoid and nonparanoid patient volunteers emphasize the importance of considering symptom-based subgroups and baseline levels of activity in future investigations of neural activation in schizophrenia.

Objective: Type 2 diabetes is the most common metabolic disorder worldwide. Traditional herbs and spices can be used to control blood glucose concentrations. The objective of this study was to evaluate the effects of the daily intake of three grams cinnamon over eight weeks on glycemic status, lipid profiles and body composition in type 2 diabetic patients. Methods: A double blind, randomized, placebo controlled clinical trial was conducted on 44 patients with type 2 diabetes. Participants were randomly assigned to take either a three g/day cinnamon supplement (n=22) or a placebo (n=22) for eight weeks. Weight, height, body fat mass and systolic and diastolic blood pressure were measured at baseline and after intervention. The fasting blood glucose, insulin, HbA1c, total cholesterol, LDL C, HDL C, Apo lipoprotein A I and B were measured at baseline and endpoint. Results: From 44 subjects participated in this study 37 completed the study. There were no significant differences in baseline characteristics, dietary intake and physical activity between groups. In the treatment group, the levels of fasting blood glucose, HbA1c, triglyceride, weight, BMI and body fat mass decreased significantly compared to baseline, but not in placebo group. No significant differences were observed in glycemic status indicators, lipid profile and anthropometric indicators between the groups at the end of intervention. Conclusion: These data suggest that cinnamon may have a moderate effect in improving glycemic status indicators. PMID:22973482

To investigate the longitudinal spinal cord and brain changes in neuromyelitis optica (NMO) and multiple sclerosis (MS) and their associations with disability progression. We recruited 28 NMO, 22 MS, and 20 healthy controls (HC), who underwent both spinal cord and brain MRI at baseline. Twenty-five NMO and 20 MS completed 1-year follow-up. Baseline spinal cord and brain lesion loads, mean upper cervical cord area (MUCCA), brain, and thalamus volume and their changes during a 1-year follow-up were measured and compared between groups. All the measurements were also compared between progressive and non-progressive groups in NMO and MS. MUCCA decreased significantly during the 1-year follow-up in NMO not in MS. Percentage brain volume changes (PBVC) and thalamus volume changes in MS were significantly higher than NMO. MUCCA changes were significantly different between progressive and non-progressive groups in NMO, while baseline brain lesion volume and PBVC were associated with disability progression in MS. MUCCA changes during 1-year follow-up showed association with clinical disability in NMO. Spinal cord atrophy changes were associated with disability progression in NMO, while baseline brain lesion load and whole brain atrophy changes were related to disability progression in MS. • Spinal cord atrophy progression was observed in NMO. • Spinal cord atrophy changes were associated with disability progression in NMO. • Brain lesion and atrophy were related to disability progression in MS.

Objectives We aimed to examine whether the C-reactive protein (CRP) level could be used to differentiate between major depressive disorder (MDD) and bipolar II disorder (BD II). Methods Ninety-six healthy controls, 88 BD II and 72 MDD drug-naïve patients in their major depressive episodes were enrolled. The fasting plasma level of high-sensitivity CRP was assessed at baseline and after treatment. Results The BD II patients presented significantly higher 17-item Hamilton Depression Rating Scale (HDRS) scores and CRP levels at baseline when adjustment for age, gender, and body mass index (P < 0.001 and P < 0.001, respectively). After treatment the CRP levels remained significantly different (P < 0.001), although the HDRS score was not significantly different between the BD II and MDD patients. A receiver-operating characteristic analysis showed that a baseline CRP level of 621.6 ng/mL could discriminate between BD II and MDD, with an area under the curve of 0.816 and a sensitivity and specificity of 0.699 and 0.882, respectively. Furthermore, the baseline CRP level greater than 621.6 ng/ml had 28.2 higher odds of a diagnosis of BD II (P < 0.001, 95% confidence interval: 10.96-72.35). Conclusions The level of CRP plays a role of biomarker to differentiate between MDD and BD II depression in both their depressed and euthymic state.

Overweight and obesity are globally increasing risk factors for diseases in the context of metabolic syndrome. A randomized controlled trial was conducted to investigate whether there are any existing differences between two lifestyle intervention strategies with respect to weight reduction after 1 year. A total of 166 subjects with a body mass index of 28-35 kg/m 2 were enrolled in this trial at seven study centers; 109 were randomly allocated to the intervention group (comprehensive lifestyle modification program: web-based Individual Health Management [IHM]) with 3-month reduction phase plus 9-month maintenance phase, and 57 were allocated to the control group (written information with advice for healthy food habits: usual care [UC]). Body weight, waist circumference, blood pressure, laboratory findings, and bioimpedance analysis used to determine body composition were measured at baseline and after 3, 6, 9, and 12 months. The primary outcome parameter was body weight at month 12 compared to baseline. With respect to baseline status there were no statistically significant differences between the groups. Based on the intent-to-treat population, body weight showed a mean decrease of 8.7 kg (SD 6.1) in the intervention group (IHM) and 4.2 kg (SD 5) in the control group (UC) at month 12. This statistically significant difference ( P <0.001) was confirmed by various sensitivity analyses. Body mass index, waist circumference, high-density lipid cholesterol, body fat, and the ratio of fat and body cell mass improved to a significantly higher degree in the IHM group. IHM proved to be superior to UC in weight reduction after 1 year. With a mean loss of about 10% of the baseline weight, a clinically high relevant risk reduction for cardio-metabolic diseases is achievable.

SUMMARY Objectives To examine informant validity using the Community Screening Interview for Dementia (CSI ‘D’) both cross-sectionally and longitudinally in two very different cultures and to explore the effects of informants and study participants’ characteristics on the validity of informants’ reports. Methods Elderly African Americans age 65 years and older residing in Indianapolis, USA and elderly Yoruba Nigerians age 65 years and older residing in Ibadan, Nigeria were assessed on cognitive functioning using the CSI ‘D’ at baseline (1992–1993) and five-year follow-up (1997–1998). At baseline, the informant validity in both samples was evaluated against participants’ cognitive tests using Pearson correlation and regular regression models. At follow-up, informants ratings on cognitive decline were assessed against participants’ cognitive decline scores from baseline to follow-up using biserial correlation and logistic regressions. Results At baseline, informants’ reports on cognitive functioning significantly correlated with cognitive scores in both samples (Indianapolis:r = –0.43, p < 0.001; Ibadan:r = –0.47, p < 0.001). The participant–informant relationships significantly affected the informants’ reports in the two samples with different patterns (p = 0.005 for Indianapolis and p < 0.001 for Ibadan) at a given level of cognitive functioning. African Americans spouses reported more cognitive problems, while siblings reported more problems for the Yoruba Nigerians. At follow-up, informants’ ratings on cognitive decline significantly correlated with the cognitive decline scores (Indianapolis r = 0.38, p < 0.001; Ibadan r = 0.32, p < 0.001). The characteristics of study participants and informants had little impact on the informants’ ratings on cognitive decline. Conclusions Informant reports are valid in assessing the cognitive functioning of study participants both cross-sectionally and longitudinally in two very different cultures, languages and environments.

Cerebrovascular reactivity (CVR) is an important metric of cerebrovascular health. While the BOLD fMRI method in conjunction with carbon-dioxide (CO2) based vascular manipulation has been the most commonly used, the BOLD signal is not a direct measure of vascular changes, and the use of arterial-spin labeling (ASL) cerebral blood flow (CBF) imaging is increasingly advocated. Nonetheless, given the differing dependencies of BOLD and CBF on vascular baseline conditions and the diverse CO2 manipulation types currently used in the literature, knowledge of potential biases introduced by each technique is critical for the interpretation of CVR measurements. In this work, we use simultaneous BOLD-CBF acquisitions during both vasodilatory (hypercapnic) and vasoconstrictive (hypocapnic) stimuli to measure CVR. We further imposed different levels of baseline vascular tension by inducing hypercapnic and hypocapnic baselines, separately from normocapnia by 4 mm Hg. We saw significant and diverse dependencies on vascular stimulus and baseline condition in both BOLD and CBF CVR measurements: (i) BOLD-based CVR is more sensitive to basal vascular tension than CBF-based CVR; (ii) the use of a combination of vasodilatory and vasoconstrictive stimuli maximizes the sensitivity of CBF-based CVR to vascular tension changes; (iii) the BOLD and CBF vascular response delays are both significantly lengthened at predilated baseline. As vascular tension can often be altered by potential pathology, our findings are important considerations when interpreting CVR measurements in health and disease. PMID:25655446

Whether plantar fascia-specific stretching or shock-wave therapy is effective as an initial treatment for proximal plantar fasciopathy remains unclear. The aim of this study was to test the null hypothesis of no difference in the effectiveness of these two forms of treatment for patients who had unilateral plantar fasciopathy for a maximum duration of six weeks and which had not been treated previously. One hundred and two patients with acute plantar fasciopathy were randomly assigned to perform an eight-week plantar fascia-specific stretching program (Group I, n = 54) or to receive repetitive low-energy radial shock-wave therapy without local anesthesia, administered weekly for three weeks (Group II, n = 48). All patients completed the seven-item pain subscale of the validated Foot Function Index and a patient-relevant outcome questionnaire. Patients were evaluated at baseline and at two, four, and fifteen months after baseline. The primary outcome measures were a mean change in the Foot Function Index sum score at two months after baseline, a mean change in item 2 (pain during the first few steps of walking in the morning) on this index, and satisfaction with treatment. No difference in mean age, sex, weight, or duration of symptoms was found between the groups at baseline. At two months after baseline, the Foot Function Index sum score showed significantly greater changes for the patients managed with plantar fascia-specific stretching than for those managed with shock-wave therapy (p < 0.001), as well as individually for item 2 (p = 0.002). Thirty-five patients (65%) in Group I versus fourteen patients (29%) in Group II were satisfied with the treatment (p < 0.001). These findings persisted at four months. At fifteen months after baseline, no significant between-group difference was measured. A program of manual stretching exercises specific to the plantar fascia is superior to repetitive low-energy radial shock-wave therapy for the treatment of acute symptoms of proximal plantar fasciopathy.

The purpose of this study is to determine baseline vitreous humor temperature during a combined phacoemulsification and pars plana vitrectomy (PPV) procedure; to determine what is the temperature variation during phacoemulsification; and to compare vitreous temperature to sublingual temperature. The methods used are prospective, interventional and comparative study. Patients with a diagnosis of cataract and vitreous hemorrhage, programed for a combined procedure of phacoemulsification and PPV, were included. Patients were excluded if posterior capsular rupture existed during the anterior segment procedure. A thermoprobe was inserted through a PPV trocar. Measurement of the vitreous temperature was obtained at baseline and throughout phacoemulsification, at the end of every surgical step, and every 5 min. Sublingual temperature was measured with the same probe at the end of the surgery. Room temperature was registered. Seventeen eyes of 17 patients were included. Mean sublingual temperature was 36.5 °C (standard deviation [σ] 0.26 °C). Mean total vitreous temperature was 31.47 °C (σ 2.1 °C). Mean baseline vitreous temperature was 33.04 °C (σ 0.99 °C). Comparison of sublingual temperature with baseline vitreous temperature resulted in a significant difference (t test P < 0.000. 95 % confidence interval 2.93-3.98). Temperature measured by surgical step and surgical time presented a significant decrease in temperature from baseline (Kruskal-Wallis P < 0.000, P = 0.003, respectively). Vitreous humor is significantly hypothermic when compared to sublingual temperature. Vitreous temperature decreases significantly during phacoemulsification.

Subclinical hypothyroidism (SCH) is a common disorder which has adverse cardiovascular effects. Epicardial adipose tissue (EAT), a novel marker of cardiovascular risk, is increased in SCH. We aimed to investigate whether L-thyroxine treatment can reverse the thickening of EAT in SCH. Forty-four patients with SCH and 42 euthyroid control subjects were included. EAT thickness was measured using transthoracic echocardiography at baseline and after restoration of the euthyroid status with 3 months of L-thyroxine treatment. At baseline, mean EAT thickness was significantly greater in the SCH group when compared to the control group (6.3 ± 1.7 mm vs. 4.1 ± 0.9 mm, respectively, p < 0.001). There was a significant positive correlation between baseline serum thyroid stimulating hormone (TSH) level and EAT thickness in the SCH group. There was a significant reduction in mean EAT thickness in response to L-thyroxine treatment (6.3 ± 1.7 mm vs. 5.1 ± 1.4 mm, p < 0.001). The decrease in EAT thickness after L-thyroxine treatment when compared to baseline (DEAT) significantly correlated to the difference in TSH levels before and after treatment (DTSH; r = 0.323; p = 0.032). Epicardial adipose tissue thickness is increased in patients with SCH. This thickening was alleviated with restoration of the euthyroid status with L-thyroxine treatment in our study population of predominantly male, relatively old subjects with greater baseline EAT thickness.

Retrospective analysis of prospective data. The aim of this study was to reveal baseline predictors of persistent postlaminoplasty neck pain. Axial neck pain is one of the most common complications after cervical laminoplasty; however, baseline predictors of persistent postlaminoplasty neck pain are unclear. We analyzed data from 156 patients who completed a 2-year follow-up after double-door laminoplasty for degenerative cervical myelopathy. Patients rated the average intensity of axial neck pain in the last month using an 11-point numerical rating scale preoperatively and at the 2-year follow-up. The dependent variable was the presence of moderate-to-severe neck pain (numerical rating scale ≥4) at the 2-year follow-up. The independent variables included patient characteristics, baseline radiological parameters, surgical variables, baseline axial neck pain intensity, and baseline functions, which were measured by the Japanese Orthopaedic Association score and the Short Form-36 survey (SF-36). Logistic regression analysis was performed to identify independent predictors of moderate-to-severe neck pain after laminoplasty. At the 2-year follow-up, 51 patients (32%) had moderate-to-severe neck pain, and 106 patients (68%) had no or mild pain. Univariate analysis revealed that the ratio of cervical anterolisthesis, ratio of current smoking, baseline neck pain intensity, and baseline SF-36 Mental Component Summary differed significantly between the groups. Multivariate logistic regression analysis showed that independent predictors of moderate-to-severe neck pain at the 2-year follow-up include the presence of anterolisthesis, current smoking, moderate-to-severe baseline neck pain, and lower SF-36 Mental Component Summary. The presence of anterolisthesis and moderate-to-severe baseline neck pain were also associated with significantly poorer physical function after surgery. The presence of anterolisthesis was associated not only with the highest odds ratio of persistent neck pain but also with significantly poorer functional outcomes. Indications for cervical laminoplasty should be carefully determined in patients with cervical anterolisthesis. 4.

Aberrant expression of angiogenic factors has been anecdotally documented in brain arteriovenous malformation (AVM) nidus vessels; however, no data is available on the effect of radiosurgery on the levels of angiogenic factors in AVM patients. We sought to determine the plasma contents of VEGF, TGF-β, Ang-2 and bFGF in 28 brain AVM patients at baseline and post radiosurgery and further analyzed the relationship between plasma contents of these angiogenic factors with clinicopathologic variables of these patients. We enrolled brain AVM patients who underwent Cyberknife radiosurgery at our hospital between January 2014 and December 2015. Brain AVM was confirmed by cerebral angiography and radiosurgery was performed with Cyberknife irradiation. Plasma contents of VEGF, TGF-β, Ang-2 and bFGF were analyzed using commercially available enzyme-linked immunoassay (ELISA) kits. The baseline plasma VEGF content was 222.63 pg/mL (range 43.25-431.25 pg/mL). At three months post surgery, there was a significant -34.29% decline in plasma VEGF content versus baseline (P = 0.000). Furthermore, the median baseline plasma VEGF levels were higher in brain AVM with a nidus volume ≥ 10 cm 3 ) than those with a nidus volume < 10 cm 3 [median(IQR) 293.5 (186.5,359.25) vs. 202 (59.75, 270.75) pg/mL, P = 0.057]. The baseline plasma TGF-β content was 556.17 pg/mL (range 44.44-1486.11 pg/mL) and there was a significant -27.47% decline in plasma TGF-β content at 3 months post radiosurgery versus baseline (P = 0.015). Moreover, the baseline plasma ANG-2 content was 214.27 pg/mL (range 77.14-453.76 pg/mL). There was an immediate and significant -12.47% decline in plasma ANG-2 content post surgery versus baseline (P = 0.002). At three months post surgery, the plasma ANG-2 content still remained significantly depressed versus baseline (P = 0.002). In addition, the baseline plasma bFGF content was 9.17 pg/mL (range 3.67-36.78 pg/mL). No significant difference in plasma bFGF content was observed immediately post surgery and 3 months post surgery versus baseline (P = 0.05). Radiosurgery for brain AVM patients significantly reduced the plasma levels of angiogenic factors. The plasma angiogenic factors may be candidate markers for aberrant agniogenesis of brain AVM and patient response to radiosurgery. Copyright © 2018 Elsevier Inc. All rights reserved.

To investigate the predictive value of various molecular forms of prostate-specific antigen in men with baseline prostate-specific antigen <2.0 ng/mL. The case cohort comprised 150 men with a baseline prostate-specific antigen level <2.0 ng/mL, and who developed prostate cancer within 10 years. The control cohort was 300 baseline prostate-specific antigen- and age-adjusted men who did not develop prostate cancer. Serum prostate-specific antigen, free prostate-specific antigen, and [-2] proenzyme prostate-specific antigen were measured at baseline and last screening visit. The predictive impact of baseline prostate-specific antigen- and [-2] proenzyme prostate-specific antigen-related indices on developing prostate cancer was investigated. The predictive impact of those indices at last screening visit and velocities from baseline to final screening on tumor aggressiveness were also investigated. The baseline free to total prostate-specific antigen ratio was a significant predictor of prostate cancer development. The odds ratio was 6.08 in the lowest quintile baseline free to total prostate-specific antigen ratio subgroup. No serum indices at diagnosis were associated with tumor aggressiveness. The Prostate Health Index velocity and [-2] proenzyme prostate-specific antigen/free prostate-specific antigen velocity significantly increased in patients with higher risk D'Amico risk groups and higher Gleason scores. Free to total prostate-specific antigen ratio in men with low baseline prostate-specific antigen levels seems to predict the risk of developing prostate cancer, and it could be useful for a more effective individualized screening system. Longitudinal changes in [-2] proenzyme prostate-specific antigen-related indices seem to correlate with tumor aggressiveness, and they could be used as prognostic tool before treatment and during active surveillance. © 2017 The Japanese Urological Association.

Our purpose was to evaluate the relationship between subfoveal choroidal thickness (SCT) and development of macular atrophy (MA) in eyes with age-related macular degeneration (AMD). This was a prospective, multicenter study. Sixty participants (120 eyes) in the TREX-AMD trial (NCT01648292) with treatment-naïve neovascular AMD (NVAMD) in at least one eye were included. SCT was measured by certified reading center graders at baseline using spectral domain optical coherence tomography (SDOCT). The baseline SCT was correlated with the presence of MA at baseline and development of incident MA by month 18. Generalized estimating equations were used to account for information from both eyes. Baseline SCT in eyes with MA was statistically significantly less than in those without MA in both the dry AMD (DAMD) (P = 0.04) and NVAMD (P = 0.01) groups. Comparison of baseline SCT between MA developers and non-MA developers revealed a statistically significant difference (P = 0.03). Receiver operating characteristic curve (ROC) analysis showed the cut-off threshold of SCT for predicting the development of MA in cases without MA at baseline was 124 μm (AUC = 0.772; Sensitivity = 0.923; Specificity = 0.5). Among eyes without MA at baseline, those with baseline SCT ≤124 μm were 4.3 times more likely to develop MA (Odds ratio: 4.3, 95% confidence interval: 1.6-12, P = 0.005) than those with baseline SCT >124 μm. Eyes with AMD and MA had less SCT than those without MA. Eyes with less baseline SCT also appear to be at higher risk to develop MA within 18 months.

This study's objective was to determine whether two distinct carbohydrate (CHO)-modified diets and a standard portion-controlled (PC) diet differentially impacted children's eating behaviors and whether eating behavior scores predicted lower BMI among children with obesity. Children (n = 102) aged 7-12 years with obesity were randomly assigned to a 12-month intervention of a low-carbohydrate (LC), reduced glycemic load (RGL), or standard PC diet. The Three-Factor Eating Questionnaire (TFEQ) was completed at baseline, 3, 6, and 12 months by parents to characterize their child's hunger (H), disinhibition (D), and cognitive restraint (CR). Baseline and follow-up TFEQ scores by diet were evaluated relative to BMI status over time. All diet groups showed increased CR and decreased H and D from baseline to 3 months, with differences from baseline remaining at 12 months for CR and H. Lower BMI status during study follow-up was associated with different TFEQ scores by diet group (LC and RGL: higher CR; PC: lower H), adjusting for sex, age, and race. Higher CR at follow-up was predicted by race and higher baseline CR; only lower H at baseline predicted lower H at follow-up. Eating behaviors improved significantly with all diets during the initial 3 months; higher CR and lower H were sustained at treatment's end. BMI outcomes were associated with different eating behaviors in CHO-modified diet groups compared with PC diets. Targeting diets of children with obesity with specific baseline characteristics may lead to improved outcomes.

The aim of this study was to compare humoral and cellular immune responses to influenza vaccination in cancer survivors with and without severe symptoms of fatigue. Severely fatigued (n = 15) and non-fatigued (n = 12) disease-free cancer survivors were vaccinated against seasonal influenza. Humoral immunity was evaluated at baseline and post-vaccination by a hemagglutination inhibition assay. Cellular immunity was evaluated at baseline and post-vaccination by lymphocyte proliferation and activation assays. Regulatory T cells were measured at baseline by flow cytometry and heat-shock protein 90 alpha levels by ELISA. Comparable humoral immune responses were observed in fatigued and non-fatigued patients, both pre- and post-vaccination. At baseline, fatigued patients showed a significantly diminished cellular proliferation upon virus stimulation with strain H3N2 (1414 ± 1201 counts), and a trend in a similar direction with strain H1N1 (3025 ± 2339 counts), compared to non-fatigued patients (3099 ± 2401 and 5877 ± 4604 counts, respectively). The percentage of regulatory T lymphocytes was significantly increased (4.4 ± 2.1% versus 2.4 ± 0.8%) and significantly lower amounts of interleukin 2 were detected prior to vaccination in fatigued compared to non-fatigued patients (36.3 ± 44.3 pg/ml vs. 94.0 ± 45.4 pg/ml with strain H3N2 and 28.4 ± 44.0 pg/ml versus 74.5 ± 56.1 pg/ml with strain H1N1). Pre-vaccination heat-shock protein 90 alpha concentrations, post-vaccination cellular proliferation, and post-vaccination cytokine concentrations did not differ between both groups. In conclusion, influenza vaccination is favorable for severely fatigued cancer survivors and should be recommended when indicated. However, compared to non-fatigued cancer survivors, fatigued cancer survivors showed several significant differences in immunological reactivity at baseline, which warrants further investigation.

Patient-based outcomes with maxillary overdentures on a minimum number of implants, opposing mandibular 2-implant overdentures are not evident in the literature. To evaluate patient's satisfaction with maxillary 3-implant overdentures, opposing mandibular 2-implant overdentures, using two different attachment systems over the first 2 years of service. Forty participants wearing mandibular 2-implant overdentures for 3 years were randomly allocated to one of two similar implant system groups to receive maxillary 3-implant overdentures. Twenty participants were allocated to splinted and unsplinted attachment system treatment groups for each system. Patient satisfaction with pre-treatment complete maxillary dentures, with maxillary 3-implant overdentures at baseline and annually for 2 years, was measured using visual analogue scale questionnaires and the oral health impact profiles. Palatal coverage of the maxillary overdentures was reduced at the first annual recall. Data showed significant improvement in pain reduction, comfort, stability, and function variables of the visual analogue scale after treatment. Analysis by prosthodontic design using visual analogue scale showed no significant difference. The total oral health impact profile-14 scores after treatment for all participants, regardless of prosthodontic design, were significantly lower (more satisfied). The overall oral health impact profile-20E score at baseline was significantly higher (more satisfied) compared with pre-treatment conventional maxillary dentures. No significant changes were observed in the first or second years compared with baseline results. Twenty-two participants (84.6%) preferred reduced palatal coverage, regardless of prosthodontic design, after 1 year. Twenty participants (76.9%) still preferred reduced palatal coverage at the end of the second year. The provision of maxillary 3-implant overdentures to oppose mandibular 2-implant overdentures significantly improve levels of patient satisfaction compared with conventional maxillary dentures. © 2011 Wiley Periodicals, Inc.
Adaptive echolocation behavior in bats for the analysis of auditory scenes

Summary Echolocating bats emit sonar pulses and listen to returning echoes to probe their surroundings. Bats adapt their echolocation call design to cope with dynamic changes in the acoustic environment, including habitat change or the presence of nearby conspecifics/heterospecifics. Seven pairs of big brown bats, Eptesicus fuscus, were tested in this study to examine how they adjusted their echolocation calls when flying and competing with a conspecific for food. Results showed that differences in five call parameters, start/end frequencies, duration, bandwidth and sweep rate, significantly increased in the two-bat condition compared with the baseline data. In addition, the magnitude of spectral separation of calls was negatively correlated with the baseline call design differences in individual bats. Bats with small baseline call frequency differences showed larger increases in call frequency separation when paired than those with large baseline call frequency differences, suggesting that bats actively change their sonar call structure if pre-existing differences in call design are small. Call design adjustments were also influenced by physical spacing between two bats. Calls of paired bats exhibited the largest design separations when inter-bat distance was shorter than 0.5 m, and the separation decreased as the spacing increased. All individuals modified at least one baseline call parameter in response to the presence of another conspecific. We propose that dissimilarity between the time–frequency features of sonar calls produced by different bats aids each individual in segregating echoes of its own sonar vocalizations from the acoustic signals of neighboring bats.

Background Physical therapy can improve motor function in patients with PD. Music performance may be used to improve motor skills by rhythmic entrainment. Drumming has long been a part of traditional healing rituals worldwide, and is increasingly being utilized as a therapeutic strategy. Methods This pilot controlled prospective cohort trial assessed feasibility and effects of twice-weekly group West African drum circle classes for 6 weeks on PD patients’ quality of life, symptoms, motor findings, cognition, and mood. Ten patients with PD were recruited into the drum circle group. Ten patients with PD were matched pairwise to each of the drum circle participants, and enrolled in a no-intervention control group. Both groups completed the PD-specific Parkinson Disease Questionnaire (PDQ)-39 quality of life assessment and the Geriatric Depression Scale (GDS), and underwent motor and cognitive assessments by a rater blinded to group at baseline, 6 weeks, and 12 weeks. Results Drummers had significantly improved PDQ-39 scores from baseline to 6 weeks (−5.8, p=0.042), whereas the control group's scores were unchanged. Walking performance was significantly faster at baseline for controls; after 6 weeks of drumming this difference was no longer significant, and remained non-significant at 12 weeks. The drummers trended (p=0.069) toward improvement in walking from baseline to 12 weeks. Other outcomes did not significantly change from baseline to 6 or 12 weeks. Conclusions Drum circle classes significantly and reversibly improved quality of life in patients with PD. This pilot trial's findings merit larger controlled investigations comparing drumming classes to established interventions in PD, such as physical therapy. PMID:27340683

Background Green tea catechins may play a role in body weight regulation through interactions with the gut microbiota. Aim We examined whether green tea supplementation for 12 weeks induces changes in composition of the human gut microbiota. Methods 58 Caucasian men and women were included in a randomized, placebo-controlled design. For 12 weeks, subjects consumed either green tea (>0.56 g/d epigallocatechin-gallate + 0.28 ∼ 0.45 g/d caffeine) or placebo capsules. Fecal samples were collected twice (baseline, vs. week 12) for analyses of total bacterial profiles by means of IS-profiling, a 16S-23S interspacer region-based profiling method. Results No significant changes between baseline and week 12 in subjects receiving green tea or placebo capsules, and no significant interactions between treatment (green tea or placebo) and time (baseline and week 12) were observed for body composition. Analysis of the fecal samples in subjects receiving green tea and placebo showed similar bacterial diversity and community structures, indicating there were no significant changes in bacterial diversity between baseline and week 12 in subjects receiving green tea capsules or in subjects receiving placebo capsules. No significant interactions were observed between treatment (green tea or placebo) and time (baseline and week 12) for the gut microbial diversity. Although, there were no significant differences between normal weight and overweight subjects in response to green tea, we did observe a reduced bacterial alpha diversity in overweight as compared to normal weight subjects (p = 0.002). Conclusion Green tea supplementation for 12 weeks did not have a significant effect on composition of the gut microbiota. Trial Registration ClinicalTrials.gov NCT01556321 PMID:27054321

Gender is an important factor in child development. Especially in sub-Saharan Africa, girls have often been shown to be less likely to access education compared to boys. The consequence of this has been that that programmes addressing child development are often aimed at girls in order to redress gender imbalances. This study examines the effect of gender on the development of children attending community-based organisations in high HIV-affected areas, and explores whether community-based organisation attendance was associated with any changes in gender differences over time. Baseline data from 989 children and 12-15 month follow from 854 (86% response rate) were used to examine gender differences in children from Malawi and South Africa. At baseline, where there were differences by gender, these tended to disadvantage boys. It was found that boys were significantly more often found to be subjected to violence. Boys showed worse performance at school and more behavioural problems than girls. These gender differences persisted from baseline to follow-up. At follow-up, boys self-reported significantly worse average quality of life than girls. Only harsh discipline differed by gender in progression over time: boys experienced a stronger reduction in harsh physical discipline than girls from baseline to follow-up. Since harsh discipline was associated with boys' worse educational outcomes and behavioural problems, our data cautiously suggests that gender differences could be reduced over time. In conclusion, our data suggests that, perhaps due to the narrow equity approach focusing on provision for girls, boys may be overlooked. As a result, there are some specific experiences where boys are generally worse off. These differences have distinct ramifications for the educational and emotional development of boys. A broader equity approach to child development might be warranted to ensure that the needs of both girls and boys are considered, and that boys are not overlooked.

Improvement of attention with amphetamine in low- and high-performing rats.
Turner, Karly M; Burne, Thomas H J
2016-09-01
Attentional deficits occur in a range of neuropsychiatric disorders, such as schizophrenia and attention deficit hyperactivity disorder. Psychostimulants are one of the main treatments for attentional deficits, yet there are limited reports of procognitive effects of amphetamine in preclinical studies. Therefore, task development may be needed to improve predictive validity when measuring attention in rodents. This study aimed to use a modified signal detection task (SDT) to determine if and at what doses amphetamine could improve attention in rats. Sprague-Dawley rats were trained on the SDT prior to amphetamine challenge (0.1, 0.25, 0.75 and 1.25 mg/kg). This dose range was predicted to enhance and disrupt cognition with the effect differing between individuals depending on baseline performance. Acute low dose amphetamine (0.1 and 0.25 mg/kg) improved accuracy, while the highest dose (1.25 mg/kg) significantly disrupted performance. The effects differed for low- and high-performing groups across these doses. The effect of amphetamine on accuracy was found to significantly correlate with baseline performance in rats. This study demonstrates that improvement in attentional performance with systemic amphetamine is dependent on baseline accuracy in rats. Indicative of the inverted U-shaped relationship between dopamine and cognition, there was a baseline-dependent shift in performance with increasing doses of amphetamine. The SDT may be a useful tool for investigating individual differences in attention and response to psychostimulants in rodents.

Background Low/ered cholesterol is linked to aggression in some study designs. Cases/series have reported reproducible aggression increases on statins, but statins also bear mechanisms that could reduce aggression. Usual statin effects on aggression have not been characterized. Methods 1016 adults (692 men, 324 postmenopausal women) underwent double-blind sex-stratified randomization to placebo, simvastatin 20mg, or pravastatin 40mg (6 months). The Overt-Aggression-Scale-Modified–Aggression-Subscale (OASMa) assessed behavioral aggression. A significant sex-statin interaction was deemed to dictate sex-stratified analysis. Exploratory analyses assessed the influence of baseline-aggression, testosterone-change (men), sleep and age. Results The sex-statin interaction was significant (P=0.008). In men, statins tended to decrease aggression, significantly so on pravastatin: difference=-1.0(SE=0.49)P=0.038. Three marked outliers (OASMa-change ≥40 points) offset otherwise strong significance-vs-placebo: statins:-1.3(SE=0.38)P=0.0007; simvastatin:-1.4(SE=0.43)P=0.0011; pravastatin:-1.2(SE=0.45)P=0.0083. Age≤40 predicted greater aggression-decline on statins: difference=-1.4(SE=0.64)P=0.026. Aggression-protection was emphasized in those with low baseline aggression: age<40-and-low-baseline-aggression (N=40) statin-difference-vs-placebo=-2.4(SE=0.71)P=0.0016. Statins (especially simvastatin) lowered testosterone, and increased sleep problems. Testosterone-drop on statins predicted aggression-decline: β=0.64(SE=0.30)P=0.034, particularly on simvastatin: β=1.29(SE=0.49)P=0.009. Sleep-worsening on statins significantly predicted aggression-increase: β=2.2(SE=0.55)P<0.001, particularly on simvastatin (potentially explaining two of the outliers): β=3.3(SE=0.83)P<0.001. Among (postmenopausal) women, a borderline aggression-increase on statins became significant with exclusion of one younger, surgically-menopausal woman (N=310) β=0.70(SE=0.34)P=0.039. The increase was significant, without exclusions, for women of more typical postmenopausal age (≥45): (N=304) β=0.68(SE=0.34)P=0.048 – retaining significance with modified age-cutoffs (≥50 or ≥55). Significance was observed separately for simvastatin. The aggression-increase in women on statins was stronger in those with low baseline aggression (N=175) β=0.84(SE=0.30)P=0.006. No statin effect on whole blood serotonin was observed; and serotonin-change did not predict aggression-change. Conclusion Statin effects on aggression differed by sex and age: Statins generally decreased aggression in men; and generally increased aggression in women. Both findings were selectively prominent in participants with low baseline aggression – bearing lower change-variance, rendering an effect more readily evident.

Objective To test a new program’s effectiveness in reducing depression’s work burden. Methods A brief telephonic program to improve work functioning was tested in an early-stage randomized controlled trial (RCT) involving 79 Maine State Government employees who screened-in for depression and at-work limitations (treatment group=59; usual care group=27). Group differences in baseline to follow-up change scores on The Work Limitations Questionnaire (WLQ), WLQ Absence Module and PHQ-9 depression severity scale were tested with analysis of covariance. Results While there were no baseline group differences (p≥.05), by follow-up the treatment group had significantly better scores on every outcome and differences in the longitudinal changes were all statistically significant (p=.0.27 to .0001). Conclusions The new program was superior to usual care. The estimated productivity cost savings are $6041.70 per participant annually. PMID:22252528

In trial-based cost-effectiveness analysis baseline mean utility values are invariably imbalanced between treatment arms. A patient's baseline utility is likely to be highly correlated with their quality-adjusted life-years (QALYs) over the follow-up period, not least because it typically contributes to the QALY calculation. Therefore, imbalance in baseline utility needs to be accounted for in the estimation of mean differential QALYs, and failure to control for this imbalance can result in a misleading incremental cost-effectiveness ratio. This paper discusses the approaches that have been used in the cost-effectiveness literature to estimate absolute and differential mean QALYs alongside randomised trials, and illustrates the implications of baseline mean utility imbalance for QALY calculation. Using data from a recently conducted trial-based cost-effectiveness study and a micro-simulation exercise, the relative performance of alternative estimators is compared, showing that widely used methods to calculate differential QALYs provide incorrect results in the presence of baseline mean utility imbalance regardless of whether these differences are formally statistically significant. It is demonstrated that multiple regression methods can be usefully applied to generate appropriate estimates of differential mean QALYs and an associated measure of sampling variability, while controlling for differences in baseline mean utility between treatment arms in the trial.

Dyslipidemia has been considered as a major risk factor for coronary heart disease. Alternative medicine has a significant role in treatment of dyslipidemia. There are controversial findings regarding the effects of sour tea on dyslipidemia. The aim of this study was to evaluate the impact of aqueous extract of dried calyx of sour tea on polygenic dyslipidemia. This clinical trial was done on 43 adults (30-60 years old) with polygenic dyslipidemia that were randomly assigned to the intervention and control groups. The control group was trained in lifestyle modifications at baseline. The intervention group was trained for lifestyle modifications at baseline and received two cups of sour tea daily, and both groups were followed up for 12 weeks. Lipid profile was evaluated at baseline, and six and 12 weeks following the intervention. In addition, dietary and physical activity assessed at baseline for twelve weeks. Mean concentration of total cholesterol, HDL-C and LDL-C significantly decreased by up to 9.46%, 8.33%, and 9.80%, respectively, after 12 weeks in the intervention group in comparison to their baseline values. However, LDL-C/HDL-C ratio significantly increased by up to 3.15%, following 12 weeks in the control group in comparison to their baseline values. This study showed no difference in lipid profiles between the two groups, except for HDL-C concentrations. sour tea may have significant positive effects on lipid profile of polygenic dyslipidemia subjects and these effect might be attributed to its anthocyanins and inflation factor content. Therefore, sour tea intake with recommended dietary patterns and physical activity can be useful in regulation of lipid profile in patients with polygenic dyslipidemia.

The effect of isoflavone on endothelial function in postmenopausal women is controversial. The objective of this study was to evaluate the effect of oral isoflavone supplementation on endothelial function, as measured by flow-mediated dilation (FMD), in postmenopausal women. A meta-analysis of randomized placebo-controlled trials was conducted to evaluate the effect of oral isoflavone supplementation on endothelial function in postmenopausal women. Trials were searched in PubMed, Embase, the Cochrane Library database, and reviews and reference lists of relevant articles. Summary estimates of weighted mean differences (WMDs) and 95% CIs were obtained by using random-effects models. Meta-regression and subgroup analyses were performed to identify the source of heterogeneity. A total of 9 trials were reviewed in the present meta-analysis. Overall, the results of the 9 trials showed that isoflavone significantly increased FMD (WMD: 1.75%; 95% CI: 0.83%, 2.67%; P = 0.0002). Meta-regression analysis indicated that the age-adjusted baseline FMD was inversely related to effect size. Subgroup analysis showed that oral supplementation of isoflavone had no influence on FMD if the age-adjusted baseline FMD was > or = 5.2% (4 trials; WMD: 0.24%; 95% CI: -0.94%, 1.42%; P = 0.69). This improvement seemed to be significant when the age-adjusted baseline FMD levels were <5.2% (5 trials; WMD: 2.22%; 95% CI: 1.15%, 3.30%; P < 0.0001), although significant heterogeneity was still detected in this low-baseline-FMD subgroup. Oral isoflavone supplementation does not improve endothelial function in postmenopausal women with high baseline FMD levels but leads to significant improvement in women with low baseline FMD levels.

The aim of the present study was to test the neutralizing effect of mouthwashes on salivary pH after an acidic challenge. Twelve participants were recruited for three visits, one morning per week. Resting saliva was collected at baseline and after 2-min swishing with 20 mL orange juice as an acidic challenge. Participants then rinsed their mouth for 30 s with 20 mL water (control), an over-the-counter mouthwash (Listerine), or a two-step mouthwash, randomly assigned for each visit. Saliva was collected immediately, 15, and 45 min after rinsing. The pH values of the collected saliva were measured and analyzed with anova, followed by Student-Newman-Keuls post-hoc test (significance level: 0.05). Orange juice significantly lowered salivary pH. Immediately after rinsing, Listerine and water brought pH back to baseline values, with the pH significantly higher in the Listerine group. The two-step mouthwash raised pH significantly higher than Listerine and water, and higher than the baseline value. Salivary pH returned to baseline and was not significantly different among groups at 15 and 45 min post-rinsing. Mouth rinsing after an acidic challenge increased salivary pH. The tested mouthwashes raised pH higher than water. Mouthwashes with a neutralizing effect can potentially reduce tooth erosion from acid exposure. © 2015 Wiley Publishing Asia Pty Ltd.

Purpose Chemohormonal therapy with docetaxel and androgen deprivation therapy (ADT+D) for metastatic hormone-sensitive prostate cancer improves overall survival as compared with androgen deprivation therapy (ADT) alone. We compared the quality of life (QOL) between patients with metastatic hormone-sensitive prostate cancer who were treated with ADT+D and those who were treated with ADT alone. Methods Men were randomly assigned to ADT+ D (six cycles) or to ADT alone. QOL was assessed by Functional Assessment of Cancer Therapy-Prostate (FACT-P), FACT-Taxane, Functional Assessment of Chronic Illness Therapy-Fatigue, and the Brief Pain Inventory at baseline and at 3, 6, 9, and 12 months. The Wilcoxon signed rank test was used to examine changes over time. Mixed-effect models compared the QOL between arms at each time point. Results Seven hundred ninety men were randomly assigned (ADT+D [n = 397] and ADT[ n = 393]) and completed FACT-P (90% at baseline, 86% at 3 months, 83% at 6 months, 78% at 9 months, and 77% at 12 months). ADT+D patients reported a statistically significant decline in FACT-P at 3 months ( P < .001) but FACT-P did not differ significantly between baseline and 12 months ( P = .38). ADT+D FACT-P scores were significantly lower at 3 months ( P = .02) but significantly higher at 12 months ( P = .04) when compared with ADT FACT-P scores. Differences did not exceed the minimal clinically important difference at any time point. ADT+D patients reported significantly lower Functional Assessment of Chronic Illness Therapy-Fatigue scores at 3 months than did ADT patients ( P < .001). Over time, both arms reported significantly poorer FACT-Taxane scores ( P < .001) when compared with baseline. Brief Pain Inventory scores were similar between arms. Conclusion Although ADT+D was associated with statistically worse QOL at 3 months, QOL was better at 12 months for ADT+D patients than for ADT patients. Both arms reported a similar minimally changed QOL over time, suggesting that ADT+D is not associated with a greater long-term negative impact on QOL.

Protein supplements are routinely used after a laparoscopic gastric bypass (LGB). The aim of this study was to evaluate the impact of an amino acid supplement on glucose homeostasis and hormonal and inflammatory markers after LGB. Thirty patients undergoing LGB were randomized to receive or not 24 g of an oral supplement containing a leucine metabolite, glutamine, and arginine twice daily. Changes in weight, glucose, insulin, C-peptide, insulin sensitivity, interleukin (IL) 6, C-reactive protein (CRP), leptin, insulin-like growth factor (IGF) 1, ghrelin, and incretins were assessed preoperatively and 2 weeks and 8 weeks postoperatively. Thirty patients (96.7% female, age 46.9 ± 8.4 years, body mass index 43.3 ± 4.1 kg/m(2)) were randomized. The experimental (n = 14) and control (n = 16) groups were not significantly different at baseline. Weight loss was similar for the 2 groups. Fasting glucose decreased significantly at 2 and 8 weeks compared with base line (p < 0.0001) with no difference between the experimental and control groups (p = 0.8), but insulin and calculated insulin sensitivity, which were similar at baseline, became significantly worse in the experimental group 8 weeks after surgery (p = 0.02 for insulin; p = 0.04 for the homeostasis model assessment of insulin resistance). CRP and IL-6, which were similar at baseline, were found to be significantly higher at 8 weeks in the experimental group (p = 0.018 and p = 0.05, respectively). Leptin and IGF-1 levels decreased significantly from baseline at 2 and 8 weeks (p < 0.0001), but there was no difference between the 2 groups. No significant changes in GLP-1, ghrelin, or gastric inhibitory polypeptide were noticed after 8 weeks. An amino acid supplement had no effect on the early postoperative incretins after LGB. It may have a negative influence on glucose kinetics and degree of inflammation. Future studies are needed to clarify these effects. Copyright © 2011 American College of Surgeons.

This research evaluates the development of three environmental knowledge dimensions of secondary school students after participation in a singular 1-day outdoor education programme. Applying a cross-national approach, system, action-related and effectiveness knowledge levels of students educated in Germany and Singapore were assessed before and after intervention participation. Correlations between single knowledge dimensions and behaviour changes due to the environmental education intervention were examined. The authors applied a pre-, post- and retention test design and developed a unique multiple-choice instrument. Results indicate significant baseline differences in the prevalence of the different knowledge dimensions between subgroups. Both intervention subsamples showed a low presence of all baseline knowledge dimensions. Action-related knowledge levels were higher than those of system and effectiveness knowledge. Subsample-specific differences in performed pro-environmental behaviour were also significant. Both experimental groups showed significant immediate and sustained knowledge increases in the three dimensions after programme participation. Neither of the two control cohorts showed any significant increase in any knowledge dimension. Effectiveness knowledge improved most. The amount of demonstrated environmental actions increased significantly in both intervention groups. Both control cohorts did not show shifts in environmental behaviour. Yet, only weak correlations between any knowledge dimension and behaviour could be found.

The aim of the present study was to assess bone volume changes in maxillary molar regions after delayed implants placement. Patients presented large bone defects after tooth extractions. Reactive soft tissue was left into the defects. No grafts were used. Cone beam computed tomography (CBCT) scans were performed before tooth extractions, at implant placement (at 3 months from extraction) and 3 years after implant placement, bone volume measurements were assessed. Bucco-lingual width showed a statistically significant decrease (p = .013) at implant placement, 3 months after extraction. Moreover, a statistically significant increase (p < .01) was measured 3 years after implant placement. No statistically significant differences (p > .05) were found between baseline values (before extraction) and at 3 years from implant placement. Vertical dimension showed no statistically significant differences (p > .05) at implant placement, 3 months after extraction. Statistically significant differences (p < .0001) were found between baseline values (before extraction) and at 3 months from implant placement as well as between implant placement values and 3 years later. CT scans presented successful outcome of delayed implants placed in large bone defects at 3-year follow-up. © 2016 Wiley Periodicals, Inc.

In 770 postmenopausal women, the fracture incidence during a 4-year follow-up was analyzed in relation to the fracture probability (FRAX risk assessment tool) and risk (Garvan risk calculator) predicted at baseline. Incident fractures occurred in 62 subjects with a higher prevalence in high-risk subgroups. Prior fracture, rheumatoid arthritis, femoral neck T-score and falls increased independent of fracture incidence. The aim of the study was to analyze the incidence of fractures during a 4-year follow-up in relation to the baseline fracture probability and risk. Enrolled in the study were 770 postmenopausal women with a mean age of 65.7 ± 7.3 years. Bone mineral density (BMD) at the proximal femur, clinical data, and fracture probability using the FRAX tool and risk using the Garvan calculator were determined. Each subject was asked yearly by phone call about the incidence of fracture during the follow-up period. Of the 770 women, 62 had a fracture during follow-up, and 46 had a major fracture. At baseline, BMD was significantly lower, and fracture probability and fracture risk were significantly higher in women who had a fracture. Among women with a major fracture, the percentage with a high baseline fracture probability (>10 %) was significantly higher than among those without a fracture (p < 0.01). Fracture incidence during follow-up was significantly higher among women with a high baseline fracture probability (12.7 % vs. 5.2 %) and a high fracture risk (9.2 vs. 5.3 %) so that the "fracture-free survival" curves were significantly different (p < 0.05). The number of clinical risk factors noted at baseline was significantly associated with fracture incidence (chi-squared = 20.82, p < 0.01). Prior fracture, rheumatoid arthritis, and femoral neck T-score were identified as significant risk factors for major fractures (for any fractures, the influence of falls was also significant). During follow-up, fracture incidence was predicted by baseline fracture probability (FRAX risk assessment tool) and risk (Garvan risk calculator). A number of clinical risk factors and a prior fracture, rheumatoid arthritis, femoral neck T-score, and falls were independently associated with an increased incidence of fractures. [Corrected

We examined if the reduced risk of breast cancer events seen among women without baseline hot flash symptoms in the Women's Healthy Eating and Living (WHEL) dietary intervention trial was related to changes in sex hormone concentrations. Baseline and year one concentrations of total and bioavailable estradiol, and testosterone and sex hormone-binding globulin (SHBG) were compared by intervention arm among 447 postmenopausal women without hot flashes. Cox proportional hazard models tested interaction terms between study arm and baseline hormone concentrations adjusted for study site, antiestrogen use, positive nodes, tumor size, oophorectomy status, and hormone replacement therapy use. Sex hormone concentrations did not differ by study arm at baseline nor at year one. Twenty-two (9.8%) events occurred in the intervention arm versus 42 (18.9%) in the comparison arm (P = 0.009). Baseline bioavailable testosterone was significantly, positively associated with additional events (HR 1.69, 95% CI: 1.00-2.84; P = 0.049). There were significant interactions between the intervention and total (P = 0.015), and bioavailable (P = 0.050) testosterone: the intervention was more protective among participants with higher baseline total (HR 0.3, 95% CI: 0.2-0.7) or bioavailable (HR 0.4, 95% CI: 0.2-0.7) testosterone than for participants with lower baseline total (HR 0.8, 95% CI: 0.4-1.5) or bioavailable (HR 0.8, 95% CI: 0.4-1.5) testosterone. No significant effects were seen for estradiol or SHBG. The WHEL dietary intervention may have modified other risk factors of recurrence correlated with testosterone. Sex hormones should be considered as part of a larger biological system related to the risk of breast cancer recurrence. ©2011 AACR.

Several authors have tried to predict the risk of radiographic progression in RA according to baseline characteristics, considering exposure to treatment only as a binary variable (Treated: Yes/No). This study aims to model the risk of 5-year radiographic progression taking into account both baseline characteristics and the cumulative time-varying exposure to corticosteroids or DMARDs. The study population consisted of 403 patients of the Etude et Suivi des Polyarthrites Indifférenciées Récentes cohort meeting the 1987 ACR or 2010 ACR/EULAR criteria for RA at inclusion and having complete radiographic data at baseline and 5 years. Radiographic progression was defined at 5 years as a significant increase of the Sharp/van der Heidje score (smallest detectable difference ⩾5). The best logistic regression model was selected from the following: model including only clinico-biological baseline characteristics; model considering baseline characteristics and treatments as binary variables; and model considering baseline characteristics and treatments as weighted cumulative exposure variables. Radiographic progression occurred in 143 (35.5%) patients. The best model combined anti-citrullinated peptide antibody positivity, ESR, swollen joint count >14 and erosion score at baseline, as well as corticosteroids, MTX/LEF (MTX or LEF) and biologic DMARDs (bDMARDs) as weighted cumulative exposure variables. Recent cumulative exposure to high doses of corticosteroids (⩽ 3months) was significantly associated with the risk of 5-year radiographic progression and a significant protective association was highlighted for a 36-month exposure to bDMARDs. Corticosteroids and bDMARDs play an important role in radiographic progression. Accounting for treatment class and intensity of exposure is a major concern in predictive models of radiographic progression in RA patients.

People robustly associate various sound attributes with specific smells/tastes, and soundtracks that are associated with specific tastes can influence people’s evaluation of the taste of food and drink. However, it is currently unknown whether such soundtracks directly impact the eating experience via physiological changes (an embodiment account), or whether they act at a higher cognitive level, or both. The present research assessed a version of the embodiment account, where a soundtrack associated with sourness is hypothesized to induce a physiological response in the listener by increasing salivary flow. Salivation was measured while participants were exposed to three different experimental conditions – a sour soundtrack, a muted lemon video showing a man eating a lemon, and a silent baseline condition. The results revealed that salivation during the lemon video condition was significantly greater than in the sour soundtrack and baseline conditions. However, contrary to our hypothesis, there was no significant difference between salivation levels in the sour soundtrack compared to the baseline condition. These results are discussed in terms of potential mechanisms underlying the auditory modulation of taste perception/evaluation. PMID:28491044

We assessed the relationship between alcohol consumption in young adulthood (ages 18-30 years) and occupational success 15 years later among Blacks and Whites. We analyzed data from the Coronary Artery Risk Development in Young Adults Study on employment status and occupational prestige at year 15 from baseline. The primary predictor was weekly alcohol use at baseline, after stratification by race and adjustment for socioeconomic factors. We detected racial differences in the relationship between alcohol use in early adulthood and employment status at midlife. Blacks who were very heavy drinkers at baseline were more than 4 times as likely as Blacks who were occasional drinkers to be unemployed at year 15 (odds ratio [OR]=4.34; 95% confidence interval [CI]=2.22, 8.47). We found no statistically significant relationship among Whites. Occupational prestige at midlife was negatively related to very heavy drinking, but after adjustment for marital status, active coping, life stress, and educational attainment, this relationship was statistically significant only among Blacks. Heavy drinking during young adulthood was negatively associated with labor market success at midlife, especially among Blacks.

Synaptic memory consolidation is thought to rely on catecholaminergic signaling. Eventually, it is followed by systems consolidation, which embeds memories in a neocortical network. Although this sequence was demonstrated in rodents, it is unclear how catecholamines affect memory consolidation in humans. Here, we tested the effects of catecholaminergic modulation on synaptic and subsequent systems consolidation. We expected enhanced memory performance and increased neocortical engagement during delayed retrieval. Additionally, we tested if this effect was modulated by individual differences in a cognitive proxy measure of baseline catecholamine synthesis capacity. Fifty-three healthy males underwent a between-subjects, double-blind, placebo-controlled procedure across 2 days. On day 1, subjects studied and retrieved object-location associations and received 20 mg of methylphenidate or placebo. Drug intake was timed so that methylphenidate was expected to affect early consolidation but not encoding or retrieval. Memory was tested again while subjects were scanned three days later. Methylphenidate did not facilitate memory performance, and there was no significant group difference in activation during delayed retrieval. However, memory representations differed between groups depending on baseline catecholamines. The placebo group showed increased activation in occipito-temporal regions but decreased connectivity with the hippocampus, associated with lower baseline catecholamine synthesis capacity. The methylphenidate group showed stronger activation in the postcentral gyrus, associated with higher baseline catecholamine synthesis capacity. Altogether, methylphenidate during early consolidation did not foster long-term memory performance, but it affected retrieval-related neural processes depending on individual levels of baseline catecholamines.

The adverse effects of spinal anesthesia (SA) include arterial hypotension and bradycardia. The aim of this study was to compare the effects of 2 type 3 serotonin receptor antagonists in SA-induced adverse effects. Specifically, we assessed whether ramosetron was more effective than ondansetron in reducing SA-induced decreases in blood pressure (BP) and heart rate (HR). A total of 117 patients undergoing orthopedic surgery and receiving SA were intravenously administered 0.3 mg of ramosetron (n = 39, group R), 4 mg of ondansetron (n = 39, group O4), or 8 mg of ondansetron (n = 39, group O8). Systolic BP (SBP), diastolic BP (DBP), mean BP (MBP), HR, and the lowest SBP, DBP, MBP, and HR values were measured preoperatively (baseline) and intraoperatively. The incidence of postoperative nausea and vomiting, the need for rescue antiemetics, the amount of patient-controlled analgesia consumption, and pain score in the first 48 hours after surgery were determined. Baseline values did not significantly differ among the 3 groups. After SA, SBP, DBP, MBP, and HR were lower than their baseline values in all 3 groups. The differences between the baseline and the lowest values were significantly less in group R than in groups O4 and O8 with respect to SBP (P < 0.001), DBP (P = 0.001), and MBP (P < 0.001) less in group R than in group O4 with respect to HR (P = 0.032). Intergroup differences were not significant for postoperative nausea and vomiting, the need for rescue antiemetics, patient-controlled analgesia consumption, or pain score. The administration of ramosetron (0.3 mg) significantly attenuated the SA-induced decrease in BP compared with 4 or 8 mg of ondansetron and HR compared with 4 mg of ondansetron.

Chronic oxidative stress (OS) may play a role in cardiovascular disease in HIV-infected patients, and increased bilirubin levels may have a beneficial role in counteracting OS. Atazanavir (ATV) inhibits UDP-glucuronosyl-transferase 1A1 (UGT1A1), thus increasing unconjugated bilirubin levels. We aimed to compare changes in OS markers in patients on ATV/ritonavir (ATV/r)- vs. efavirenz (EFV)-based first-line antiretroviral therapy (ART). A multicentre, prospective cohort study of HIV-infected patients who started first-line ART with either ATV/r or EFV was conducted. Lipoprotein-associated phospholipase A2 (Lp-PLA2), myeloperoxidase (MPO) and oxidized low-density lipoprotein (oxLDL) were measured for 145 patients in samples obtained at baseline and after at least 9 months of ART during which the initial regimen was maintained and the patient was virologically suppressed. The change in OS markers was modelled using multiple linear regressions adjusting for baseline values and confounders. After adjustment for baseline variables, patients on ATV/r had a significantly greater decrease in Lp-PLA2 [estimated difference -16.3; 95% confidence interval (CI) -31.4, -1.25; P = 0.03] and a significantly smaller increase in OxLDL (estimated difference -21.8; 95% CI -38.0, -5.6; P < 0.01) relative to those on EFV, whereas changes in MPO were not significantly different (estimated difference 1.2; 95% CI -14.3, 16.7; P = 0.88). Adjusted changes in bilirubin were significantly greater for the ATV/r group than for the EFV group (estimated difference 1.33 mg/dL; 95% CI 1.03, 1.52 mg/dL; P < 0.01). Changes in bilirubin and changes in OS markers were significantly correlated. When compared with EFV, ATV/r-based therapy was associated with lower levels of oxidative stress biomarkers, which was in part attributable to increased bilirubin levels. © 2016 British HIV Association.

The hypothesis of this 5-y randomized clinical trial was that there would be no significant difference in the satisfaction of edentulous participants with removable complete overdentures attached to 1 or 2 mandibular implants. Secondary aims were to test changes in satisfaction between and within the groups from baseline to 5 y and differences between the groups in implant survival and prosthodontic maintenance over 5 y. Each of the 86 participants (mean age, 67 y) was randomly allocated to receive either 1 implant in the midline (group 1) or 2 implants in the canine areas (group 2) attached to a mandibular overdenture opposing a maxillary complete denture. Satisfaction was self-assessed by participants on a visual analog scale at baseline prior to implants, as well as at 2 mo and 1, 3, and 5 y with implant overdentures, whereas implant survival and prosthodontic maintenance were assessed by clinical examination. After 5 y, 29 participants in group 1 and 33 in group 2 were available, with most dropouts due to death. Satisfaction with the implant denture after 5 y was significantly (P < 0.001) higher than at baseline in both groups and remained with no significant difference (P = 0.32) between the groups. No implants failed in group 1 but 5 failed before loading in 4 participants in group 2. Most participants required maintenance or occasionally denture replacement, and although differences between the groups were not statistically significant, group 1 experienced almost twice as many fractured dentures usually adjacent to the implant attachment. We conclude that there were no significant differences after 5 y in satisfaction or survival of implants with mandibular overdentures retained by 1 implant or 2 implants. Additional research is required to confirm long-term treatment effectiveness of single-implant dentures and the implications of prosthetic maintenance with implant overdentures (ClinicalTrials.gov: NCT02117856). © International & American Associations for Dental Research 2014.

The use of oral calcium supplementation among the elderly for prevention and treatment of osteoporosis and osteopenia is increasing. The incidence of aortic valve disease and coronary artery disease also is increasing. No study thus far has been done to demonstrate whether this affects the progression of calcification in both the valves and vasculature. We sought to determine whether ingestion of oral calcium supplementation has an effect on aortic valve calcification (AVC) and coronary artery calcification (CAC). We performed an independent assessment of AVC, CAC, and calcium supplementation among patients enrolled in the Epidemiology of Coronary Artery Calcification study who were >60 years of age and had baseline and 4-year follow-up AVC data. In this population-based study of Olmsted County (Minnesota) residents, AVC and CAC scores were determined prospectively by electron beam computed tomography. We evaluated baseline demographic data and analyzed whether those patients using calcium supplementation had a higher rate of progression of both AVC and CAC. We identified 257 patients (mean age, 67.8+/-5.2 years), 144 of whom were women. Twenty-five patients (all women) reported using calcium supplements. Analysis of the 144 women (25 taking calcium supplementation) showed there was no difference in the progression of AVC (mean difference in baseline and follow-up AVC score; no supplement versus supplement, 30+/-9 vs 39+/-28; P=.73) or CAC (mean difference in baseline and follow-up CAC score; no supplement vs supplement, 47+/-15 vs 112+/-22; P=.154). There were no significant differences between the 2 groups with regard to baseline AVC, serum calcium, renal function, diabetes, hypertension, cholesterol, or body mass index. In this community-based observational study with a 4-year follow-up, no significant increased progression of AVC or CAC was found in women taking oral calcium supplementation. Larger prospective, randomized studies are needed to confirm these findings.

Constipation is the most common GI symptom in patients with diabetes mellitus (DM). Importantly, patients with constipation have lower health-related quality of life than those without constipation. Effective therapies for constipation are limited and there is a paucity of data evaluating the treatment of constipation in diabetics. Diabetic patients with chronic idiopathic constipation (CIC) as defined by Rome III criteria were recruited from outpatient clinics at a tertiary-care center and a Veterans Administration Hospital. Demographic data, baseline stool patterns, and a constipation-specific quality of life survey (Patient Assessment of Constipation Quality of Life (PAC-QOL)) were obtained. Baseline colonic transit time (CTT) was evaluated utilizing the wireless motility capsule. Patients were randomized in a double-blind fashion to 48 mcg per day lubiprostone or placebo for 8 weeks. The primary end point measured was the difference in number of spontaneous bowel movements (SBMs) per week vs. baseline for each group at each week after initiation of therapy. Secondary end points included changes in CTT after 4 weeks of therapy, PAC-QOL after 8 weeks of therapy, and changes from baseline in associated gastrointestinal (GI) symptoms as well as need for rescue medication at 2, 4, and 8 weeks. Seventy-six patients (mean age, 56.9±9.1 years, 62% females) were randomized. There were no significant differences between the two groups' baseline data or demographics. During the 8-week treatment period, patients in the lubiprostone group experienced an average of 1.83±0.80 (P=0.02) more SBMs per week than those in the placebo group as compared with baseline. The duration of CTT at Week 4 was shorter by an average of 13 h compared with baseline in the lubiprostone group, and was prolonged by an average of 7 h compared with baseline in the placebo group, leading to a treatment effect of 20.3±7.3 h (P=0.006). PAC-QOL improved in both the groups; however, there was no significant difference between the groups. There was no difference in associated GI symptoms and need for rescue medication between the two groups after 8 weeks. There were no serious adverse events reported during the study. This study suggests that lubiprostone is a safe and effective treatment for increasing weekly SBMs and decreasing CTT in patients with DM and CIC.

PURPOSE We compared the endocrine effects of 6 and 12 months of adjuvant letrozole versus tamoxifen in postmenopausal patients with hormone-responsive early breast cancer within an ongoing phase III trial. PATIENTS AND METHODS Patients were randomly assigned to receive tamoxifen, letrozole, or letrozole plus zoledronic acid. Serum values of estradiol, follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, dehydroepiandrosterone-sulphate (DHEA-S), progesterone, and cortisol were measured at baseline and after 6 and 12 months of treatment. For each hormone, changes from baseline at 6 and 12 months were compared between treatment groups, and differences over time for each group were analyzed. Results Hormonal data were available for 139 postmenopausal patients with a median age of 62 years, with 43 patients assigned to tamoxifen and 96 patients assigned to letrozole alone or combined with zoledronic acid. Baseline values were similar between the two groups for all hormones. Many significant changes were observed between drugs and for each drug over time. Namely, three hormones seemed significantly affected by one drug only: estradiol that decreased and progesterone that increased with letrozole and cortisol that increased with tamoxifen. Both drugs affected FSH (decreasing with tamoxifen and slightly increasing with letrozole), LH (decreasing more with tamoxifen than with letrozole), testosterone (slightly increasing with letrozole but not enough to differ from tamoxifen), and DHEA-S (increasing with both drugs but not differently between them). Zoledronic acid did not have significant impact on hormonal levels. CONCLUSION Adjuvant letrozole and tamoxifen result in significantly distinct endocrine effects. Such differences can explain the higher efficacy of letrozole as compared with tamoxifen.

Background Abacavir has been associated with an increased risk of acute myocardial infarction, but the pathogenic mechanisms remain unknown. We evaluated longitudinal changes in pro-atherosclerotic biomarkers in patients initiating abacavir or tenofovir. Methods Consecutive patients initiating antiretroviral therapy (ART) with abacavir/lamivudine or tenofovir/emtricitabine were included. Plasma levels of high sensitivity C reactive protein (hsCRP), interleukin-6 (IL-6), intercellular adhesion molecule-1, vascular cell adhesion molecule-1 (sVCAM-1) and plasminogen activator inhibitor-1 (PAI-1) were measured at baseline and at different time points throughout 48 weeks. Comparisons were adjusted for age, sex, ART status at inclusion, viral load, lipodystrophy, Framingham score and hepatitis C virus co-infection status. Results 50 patients were analyzed, 28 initiating abacavir and 22 tenofovir. The endothelial biomarker sVCAM-1 declined significantly in both treatment groups. hsCRP tended to increase soon after starting therapy with abacavir, a trend that was not seen in those initiating tenofovir. IL-6 significantly increased only at week 24 from baseline in patients on abacavir (+225%, p < 0.01) although the differences were not significant between groups. The procoagulant biomarker PAI-1 plasma levels increased from baseline at week 12 (+57%; p = 0.017), week 24 (+72%; p = 0.008), and week 48 (+149%; p < 0.001) in patients on tenofovir, but differences between groups were not statistically significant. Conclusion Changes in biomarkers of inflammation, coagulation, and endothelial function are not different in viremic patients starting ART with abacavir/lamivudine or tenofovir/emtricitabine. These changes occur in the early phases of treatment and include anti- and pro-atherosclerotic effects with both drugs. PMID:21294867

Recent studies have shown that a transcutaneous electrical nerve stimulation (TENS) and interferential current (IFC) application reduces pain in subjects with musculoskeletal disorders. However there are no clinical trials evaluating or comparing the muscle relaxation generated for these devices. To compare the muscle relaxation of the upper trapezius induced by the application of TENS and IFC in females with chronic nonspecific neck discomfort. Sixty-four females between 18 and 40 years of age and a history of nonspecific neck discomfort were randomly assigned to a TENS or an IFC group. The women in the TENS (N = 32; mean age 22 years) and IFC (N = 32, mean age 23 years) group were submitted to current application during 3 consecutive days and were assessed by electromyography (EMG) in different times aiming to quantify the muscular tension of the upper trapezius. A visual analogue scale (VAS) was used as pain measure at baseline (before TENS or IFC application) and at the end of the study. At baseline, demographic, pain, and EMG assessment data were similar between groups. Those in the IFC group had a significant trapezius relaxation after 3 IFC applications when compared to baseline and intermediate evaluations (P < 0.05). In contrast, the same analysis showed no significant difference between all assessments in the TENS group (P >0.05). In relation to pain relief, both groups showed an improvement at the end of the study when compared to baseline (both,P <0.05). The between-group analysis showed no difference for the subjects who received such IFC as TENS application (P <0.05). IFC induced the upper trapezius relaxation after 3 sessions in females with neck discomfort, but the TENS application did not change the muscular tension. However, these results should be carefully interpreted due to the lack of differences between groups. A significant pain decrease was found in the subjects of both groups, however, only the IFC application presented a clinically important improvement.

We sought to identify if baseline characteristic differences in patients who receive a 23 mm vs. 26 mm valve impact clinical outcomes. Transcatheter aortic valve replacement (TAVR) is currently an approved therapy for patients with severe aortic stenosis who are considered inoperable or are at high risk. We retrospectively examined baseline characteristics and outcomes of patients receiving a 23 mm (n = 132) vs. 26 mm valve (n = 81) via the transfemoral approach. Gender (P < 0.01), previous coronary artery bypass surgery (P < 0.01), history of atrial fibrillation (P = 0.04), and mean Society of Thoracic Surgeons (STS) score (P < 0.01) were significantly different between groups. There were no significant differences in the rates of minor/major vascular complications (2.2 vs. 3.7%, P = 0.68 and 13.0 vs. 12.3%, P = 0.89, respectively). Bleeding complications were also comparable (major bleed 2.3 vs. 1%, P >0.99, minor bleed 19.0 vs. 22.0%, P = 0.67 and life threatening bleed 7.0 vs. 5.0%, P = 0.77). In-hospital death (6.0 vs. 5.0%, P >0.99), 30-day all-cause death (7.6 vs. 6.2%, P = 0.69), and all-cause death at 1 year (17.4 vs. 25.9%, P = 0.13) were also similar between groups. Gender, valve size, previous coronary bypass surgery and atrial fibrillation were not independently associated with mortality; however, on multivariate analysis STS score was (HR 1.11; 95% CI 1.02-1.19; P = 0.01). Patients undergoing TAVR with 23 and 26 mm valves have similar clinical outcomes despite significant differences in baseline characteristics. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

We studied the degree and duration of effect on upper airway reflex sensitivity of oral benzocaine lozenges, nebulised lignocaine and lignocaine sprayed onto the vocal cords under direct vision, using low concentrations of ammonia as a stimulus to upper airway receptors. Ten minutes after the administration of oral benzocaine 20 mg the threshold response of the upper airway to ammonia (NH3TR) had risen significantly from baseline mean (SEM) of 680 (95) to 975 (109) ppm of ammonia with a return to baseline values after 25 min (n = 8, p < 0.05, repeated measures of ANOVA; p < 0.001, t-test). A direct spray of lignocaine 100 mg onto the vocal cords resulted in a significant elevation in NH3TR from a baseline mean (SEM) of 665 (81) to a maximum of 1600 (88) ppm of ammonia with a significant elevation in the threshold persisting for 100 min (n = 7, p < 0.001, repeated measures of ANOVA; p < 0.05, t-test). The application of 4% nebulised lignocaine 4 ml significantly increased NH3TR from a baseline mean (SEM) of 770 (56) to a maximum of 1190 (63) ppm of ammonia with a significant elevation in the threshold persisting for 30 min (n = 8, p < 0.001, repeated measures of ANOVA; p < 0.05, t-test). The maximum elevations in NH3TR with the two methods of lignocaine delivery were significantly different (p < 0.01, 2-way ANOVA).
Current methodology to assess bioequivalence of levothyroxine sodium products is inadequate.
Blakesley, Vicky A
2005-03-30
Levothyroxine sodium is a drug with a narrow therapeutic index for which an individual patient must have his or her dose carefully titrated to achieve the necessary therapeutic effect. In addition, exogenous levothyroxine cannot be distinguished from the endogenously produced hormone. Since 2004, generic formulations have been approved for the most frequently prescribed brands of levothyroxine sodium. This review examines the methodology and statistical acceptance criteria and summarizes findings of a previously published relative bioavailability study that brings into question the use of standard criteria to assess bioequivalence of levothyroxine sodium. The key findings reviewed were the following: (1) in the absence of baseline correction for endogenous T4 levels, products that differed by as much as 25% to 33% would be declared bioequivalent; (2) the use of baseline correction reduced the likelihood of declaring products bioequivalent when they actually differed by 25% to 33%; (3) even with baseline correction, products that differed by 12.5% would be declared bioequivalent; and (4) there was evidence of significant carryover from one dosing period to the next even with washout periods of up to 53 days. In conclusion, the current recommended methodology in the United States to assess bioequivalence for levothyroxine sodium products is inadequate to differentiate products that differ by 12.5%, a clinically relevant difference. Recommendations are made for modifications to the criteria that could improve the likelihood that products that differ by a clinically significant amount in their bioavailability would not be accepted as bioequivalent.

To establish a normal baseline for comparison, thirty-one thousand collagen fibril diameters were measured in calibrated transmission electron (TEM) photomicrographs of normal rabbit medial collateral ligaments (MCL's). A new automated method of quantitation was used to compare statistically fibril minimum diameter distributions in one midsubstance location in both MCL's from six animals at 3 months of age (immature) and three animals at 10 months of age (mature). Pooled results demonstrate that rabbit MCL's have statistically different (p less than 0.001) mean minimum diameters at these two ages. Interanimal differences in mean fibril minimum diameters were also significant (p less than 0.001) and varied by 20% to 25% in both mature and immature animals. Finally, there were significant differences (p less than 0.001) in mean diameters and distributions from side-to-side in all animals. These mean left-to-right differences were less than 10% in all mature animals but as much as 62% in some immature animals. Statistical analysis of these data demonstrate that animal-to-animal comparisons using these protocols require a large number of animals with appropriate numbers of fibrils being measured to detect small intergroup differences. With experiments which compare left to right ligaments, far fewer animals are required to detect similarly small differences. These results demonstrate the necessity for rigorous control of sampling, an extensive normal baseline and statistically confirmed experimental designs in any TEM comparisons of collagen fibril diameters.

Safinamide is a novel α-aminoamide with dopaminergic and non-dopaminergic properties developed as adjunctive therapy for patients with PD. Results from a 24-month double-blind controlled study suggested that as add-on to levodopa (and other PD medications) the benefits of safinamide on dyskinesia may be related to severity of dyskinesia at baseline. This post-hoc analysis further characterized the effects of safinamide on dyskinesia in mid- to late-stage PD patients. Patients were stratified by the presence or absence of dyskinesia at baseline, and by whether or not the dose of levodopa had been changed during the 24-month treatment period. Differences between safinamide and placebo were evaluated using the Wilcoxon rank-sum test. For the overall treated population (with or without baseline dyskinesia), safinamide 100 mg/day significantly improved the dyskinesia rating scale score, compared with placebo, in the subgroup of patients with no change in levodopa dose (p = 0.0488). For patients with baseline dyskinesia, improvements over placebo were also significant (p = 0.0153) in patients with or without changes in levodopa dose, and nearly significant (p = 0.0546) in patients with no change in levodopa dose, suggesting that these improvements were not due to levodopa dose reductions. While no statistically significant difference in mean DRS scores was seen between safinamide and placebo in the original study population, the present post-hoc analysis helps to provide a meaningful interpretation of the long-term effects of safinamide on dyskinesia. These results may be related to safinamide state- and use-dependent inhibition of sodium channels and stimulated glutamate release, and are unlikely due to reduced dopaminergic stimulation.

Aim: The aim of the study was to establish the baseline hematology and serum biochemistry values for Indian leopards (Panthera pardus fusca), and to assess the possible variations in these parameters based on age and gender. Materials and Methods: Hemato-biochemical test reports from a total of 83 healthy leopards, carried out as part of routine health evaluation in Bannerghatta Biological Park and Manikdoh Leopard Rescue Center, were used to establish baseline hematology and serum biochemistry parameters for the subspecies. The hematological parameters considered for the analysis included hemoglobin (Hb), packed cell volume, total erythrocyte count (TEC), total leukocyte count (TLC), mean corpuscular volume (MCV), mean corpuscular Hb (MCH), and MCH concentration. The serum biochemistry parameters considered included total protein (TP), albumin, globulin, aspartate aminotransferase, alanine aminotransferase (ALT), blood urea nitrogen, creatinine, triglycerides, calcium, and phosphorus. Results: Even though few differences were observed in hematologic and biochemistry values between male and female Indian leopards, the differences were statistically not significant. Effects of age, however, were evident in relation to many hematologic and biochemical parameters. Sub-adults had significantly greater values for Hb, TEC, and TLC compared to adults and geriatric group, whereas they had significantly lower MCV and MCH compared to adults and geriatric group. Among, serum biochemistry parameters the sub-adult age group was observed to have significantly lower values for TP and ALT than adult and geriatric leopards. Conclusion: The study provides a comprehensive analysis of hematologic and biochemical parameters for Indian leopards. Baselines established here will permit better captive management of the subspecies, serve as a guide to assess the health and physiological status of the free ranging leopards, and may contribute valuable information for making effective management decisions during translocation or rehabilitation process.

Mitochondrial dysfunction may result in a variety of diseases. The objectives here were to examine possible differences in mtDNA copy number between healthy controls and patients with depression, anxiety or stress- and adjustment disorders; the association between mtDNA copy number and disease severity at baseline; and the association between mtDNA copy number and response after an 8-week treatment (mindfulness, cognitive based therapy). A total of 179 patients in primary health care (age 20-64 years) with depression, anxiety and stress- and adjustment disorders, and 320 healthy controls (aged 19-70 years) were included in the study. Relative mtDNA copy number was measured using quantitative real-time PCR on peripheral blood samples. We found that the mean mtDNA copy number was significantly higher in patients compared to controls (84.9 vs 75.9, p<0.0001) at baseline. The difference in mtDNA copy number between patients and controls remained significant after controlling for age and sex (ß=8.13, p<0.0001; linear regression analysis). The mtDNA copy number was significantly associated with Patient Health Questionnaire (PHQ-9) scores (β=0.57, p=0.02) at baseline. After treatment, the change in mtDNA copy number was significantly associated with the treatment response, i.e., change in Hospital Anxiety and Depression Scale (HADS-D) and PHQ-9 scores (ß=1.00, p=0.03 and ß=0.65, p=0.04, respectively), after controlling for baseline scores, age, sex, BMI, smoking status, alcohol drinking and medication. Our findings show that mtDNA copy number is associated with symptoms of depression, anxiety and stress- and adjustment disorders and treatment response in these disorders.

Neutropenia is a major adverse event of docetaxel-based chemotherapy. The present study was undertaken to evaluate the incidence of neutropenia and to develop a nomogram for predicting Grade 4 neutropenia during the first cycle of docetaxel-based chemotherapy in patients with castration-resistant prostate cancer (CRPC). This study included 112 patients with CRPC treated with docetaxel-based systemic chemotherapy. We evaluated the incidence and risk factors for Grade 4 neutropenia in the first cycle of chemotherapy. Sixty-two of 112 patients (55.4%) developed Grade 4 neutropenia in the first cycle of docetaxel-based chemotherapy. There were significant differences in age, baseline white blood cell count, and baseline neutrophil count between patients with non-Grade 4 neutropenia and those with Grade 4 neutropenia in univariate analyses. The serum prostate-specific antigen level, hemoglobin level, creatinine, albumin, Eastern Cooperative Oncology Group performance status, metastatic sites, extent of disease, and history of external beam radiotherapy to the prostate were not significantly different between the 2 groups. Multivariate logistic regression analysis showed that age (odds ratio [OR], 1.08; P = .019) and baseline neutrophil counts (OR, 0.79; P = .045) were significant independent risk factors for severe neutropenia. A nomogram and a calibration plot on the basis of these results were developed from a multivariate logistic regression analysis to predict the probability of Grade 4 neutropenia. Age and baseline neutrophil counts were significant independent risk factors for Grade 4 neutropenia. The nomogram to predict it provides useful information for the management of patients with CRPC treated with docetaxel chemotherapy. Copyright © 2016 Elsevier Inc. All rights reserved.

Short stature represents one of the main features of children with Noonan syndrome. The reason for impaired growth remains largely unknown. To assess GH and IGF1 secretion in children with Noonan syndrome. 12 prepubertal children with Noonan syndrome due to mutations in the PTPN11 gene [7 males, 6 females; median age, years: 8.6 (range 5.1-13.4)] were studied; 12 prepubertal children with short stature (SS) [7 males, 5 females; median age, years: 8.1 (range 4.8-13.1)] served as the control group. GH secretion after arginine stimulation test; IGF1 generation test by measurement of IGF1 levels before and after recombinant GH (rGH) administration (0.05 mg/kg/day for 4 days). Baseline and stimulated peak values of GH were not significantly different between the two groups. At +120 minutes, GH levels remained significantly higher (p = 0.0121) in comparison with baseline values in children with Noonan syndrome. Baseline IGFI levels in patients and in SS controls were not significantly different, in contrast to values after the rGH generation test [205 ng/mL (interquartiles 138.2-252.5 ng/mL) and 284.5 ng/mL (interquartiles 172-476 ng/mL), respectively; p = 0.0248]. IGF1 values were significantly related to height (baseline: r = 773, p = 0.0320; peak: r = 0.591, p = 0.0428) in children with Noonan syndrome. Blunted increase of IGF1 after the rGH generation test was present in children with Noonan syndrome due to mutations in the PTPN11 gene in comparison with SS children. This finding may be due to partial GH resistance in the former likely related to altered Ras-MAPK signaling pathway.

Since exercise increases the production of reactive oxygen species in different tissues, the objective of this study is to evaluate, compare and correlate the acute effects of aerobic and resistance exercise in circulatory markers of oxidative stress and acylated ghrelin (AG) in postmenopausal women. Ten postmenopausal women completed different protocols: a control session (CON), an aerobic exercise session (AERO); and a single-set (SSR) or 3-set (MSR) resistance exercise protocol. After exercise, both MSR (P = .06) and AERO (P = .02) sessions showed significant increased lipid peroxidation compared with baseline levels. CON and SSR sessions showed no differences after exercise. No differences were found between sessions at any time for total glutathione, glutathione dissulfide or AG concentrations. Exercise significantly increased lipid peroxidation compared with baseline values. As pro oxidant stimuli is necessary to promote chronic adaptations to the antioxidant defenses induced by exercise, our findings are important to consider when evaluating exercise programs prescription variables aiming quality of life in this population.

Abstract To evaluate the efficacy of a functional microarray of microneedles (MNs) plus topical tranexamic acid (TA) for melasma in middle-aged women in China. Thirty female subjects with melasma were enrolled in this study. The left or right side of the face was chosen randomly to be pretreated with a functional microarray of MNs, followed by topical 0.5% TA solution once per week for 12 weeks. The other half-face was the control, treated with a sham device plus topical 0.5% TA solution. At baseline and at weeks 4, 8, and 12 of treatment, clinical (photographic) evaluations and parameters determined by Visia were recorded. At baseline and week 12, patient satisfaction scores and the biophysical parameters measured by Mexameter were also recorded. Side effects were evaluated at baseline and at the end of the 12 weeks. In total, 28 women (93.3%) completed the study. The brown spots’ scores measured by Visia were significantly lower on the combined therapy side than on the control side at 12 weeks after starting treatment; there was no significant difference between sides at 4 or 8 weeks. After 12 weeks, melanin index (MI) decreased significantly in both 2 groups, and the MI was significantly less on the combined side at week 12. Transepidermal water loss, roughness, skin hydration, skin elasticity, and erythema index showed no significant differences between 2 sides at baseline, 4, 8, and 12 weeks after treatment. Physicians’ evaluations of photographs showed better results at week 12 with combined therapy: >25% improvement was observed in the MNs plus TA side in 25 patients, and in the TA side in only 10 patients. Subjective satisfaction scores on both sides increased significantly. The participants were more satisfied with the results of the combined therapy side than the control side. No obvious adverse reactions were observed throughout the study. Combined therapy with a functional microarray of MNs and topical TA solution is a promising treatment for melasma. PMID:28489798

This research paper aims to propose a hybrid of ant colony optimization (ACO) and k-nearest neighbor (KNN) algorithms as feature selections for selecting and choosing relevant features from customer review datasets. Information gain (IG), genetic algorithm (GA), and rough set attribute reduction (RSAR) were used as baseline algorithms in a performance comparison with the proposed algorithm. This paper will also discuss the significance test, which was used to evaluate the performance differences between the ACO-KNN, IG-GA, and IG-RSAR algorithms. This study evaluated the performance of the ACO-KNN algorithm using precision, recall, and F-score, which were validated using the parametric statistical significance tests. The evaluation process has statistically proven that this ACO-KNN algorithm has been significantly improved compared to the baseline algorithms. The evaluation process has statistically proven that this ACO-KNN algorithm has been significantly improved compared to the baseline algorithms. In addition, the experimental results have proven that the ACO-KNN can be used as a feature selection technique in sentiment analysis to obtain quality, optimal feature subset that can represent the actual data in customer review data.

Transarterial chemoembolization (TACE) is usually followed by hepatic dysfunction. We evaluated the effects of L-carnitine on post-TACE impaired liver functions. Methods. 53 cirrhotic hepatocellular carcinoma patients at Osaka Medical College were enrolled in this study and assigned into either L-carnitine group receiving 600 mg oral L-carnitine daily or control group. Liver functions were evaluated at pre-TACE and 1, 4, and 12 weeks after TACE. Results. The L-carnitine group maintained Child-Pugh (CP) score at 1 week after TACE and exhibited significant improvement at 4 weeks after TACE (P < 0.01). Conversely, the control group reported a significant CP score deterioration at 1 week (P < 0.05) and 12 weeks after TACE (P < 0.05). L-carnitine suppressed serum albumin deterioration at 1 week after TACE. There were significant differences between L-carnitine and control groups regarding mean serum albumin changes from baseline to 1 week (P < 0.05) and 4 weeks after TACE (P < 0.05). L-carnitine caused prothrombin time improvement from baseline to 1, 4 (P < 0.05), and 12 weeks after TACE. Total bilirubin mean changes from baseline to 1 week after TACE exhibited significant differences between L-carnitine and control groups (P < 0.05). The hepatoprotective effects of L-carnitine were enhanced by branched chain amino acids combination. Conclusion. L-carnitine maintained and improved liver functions after TACE.

Plasma homovanillic acid (pHVA) and plasma methoxyhydroxyphenyl glycol (pMHPG), as well as plasma haloperidol, were measured in 33 schizophrenic patients before and during 6 weeks of haloperidol treatment. Good responders had higher baseline pHVA values compared with poor responders (17.4 +/- 8.8 ng/ml, n = 22 versus 11.4 +/- 5.0 ng/ml, n = 11, p less than 0.05). A higher than 15 ng/ml pretreatment pHVA level was associated with a more consistent clinical response to the subsequent treatment. Differential pHVA changes during treatment were also found between good and poor responders. Within the good responder group, a significant decline in pHVA over time was found. By contrast, pHVA showed a transient increase in the poor responder group. Plasma MHPG changes showed a similar pattern during treatment in good responders, although no significant differences in baseline values were found between the good (n = 13) and poor (n = 9) responders, and pMHPG showed no change during treatment in poor responders. Significant correlations between baseline pHVA and pMHPG values were found in 22 patients. Good responders and poor responders did not differ significantly in terms of age, duration of illness, severity of presenting symptoms, haloperidol dose, or plasma drug concentration. Two hypothetical subtypes of schizophrenia and both dopamine and norepinephrine systems involved in schizophrenic psychopathology are proposed.

This was the first exploratory randomized controlled study to compare the efficacy and safety of a preserved tafluprost/timolol fixed combination (TAF/TIM) with a preserved latanoprost/timolol fixed combination (LAT/TIM). This prospective, randomized, open-label study was conducted in Japanese patients with primary open-angle glaucoma, including normal-tension glaucoma or ocular hypertension. Following a 4-week LAT/TIM run-in period, eligible patients entered a 12-week treatment period, during which they received either LAT/TIM or TAF/TIM. The efficacy endpoint was the change in intraocular pressure (IOP) from baseline to week 12 and the safety endpoints included the changes from baseline to week 12 in superficial punctate keratopathy (SPK) score, tear breakup time (TBUT), and hyperemia score, as well as adverse events (AEs). At week 6, ocular symptoms were evaluated using a questionnaire. In total, 131 patients provided informed consent. Of these, 115 completed the run-in period and were assigned to receive TAF/TIM (n = 60) or LAT/TIM (n = 55). At week 12, there were no significant differences between the TAF/TIM and LAT/TIM groups in the change from baseline in trough IOP and IOP at 4-6 h after instillation. There were no significant differences between the two groups in the change from baseline to week 12 in SPK score, TBUT, and hyperemia score. However, only in the TAF/TIM group, the total SPK score and the inferior cornea SPK score were significantly lower at week 12 compared with baseline. Eye irritation and eye pain were significantly decreased in the TAF/TIM group compared with the LAT/TIM group. Two treatment-related AEs were reported in the TAF/TIM group (3.3%) and none in the LAT/TIM group, while no serious AEs were reported in either group. TAF/TIM is as effective as LAT/TIM in terms of IOP-reducing effect, with fewer ocular symptoms. TAF/TIM was associated with a significant improvement in SPK scores.

A new anesthesia system, the E-CAIOVX (GE Healthcare) enables the continuous monitoring of oxygen consumption (VO2) and carbon dioxide elimination (VCO2) during the surgical operation. The aim of this study was to evaluate the prognostic role of intraoperative baseline VO2 and VCO2 in an emergency open abdominal operation. A total of 103 patients who had an emergency open abdominal operation were enrolled in the study. VO2 and VCO2 were continuously measured from the induction of anesthesia to the end of the operation. There were significant correlations between intraoperative baseline VO2 and body surface area (BSA; P < .001, r = 0.68), VO2 and tidal volume (P < .001, r = 0.59), and VO2 and baseline body temperature (P < .0001, r = 0.49). Also, there were significant correlations between intraoperative baseline VCO2 and BSA (P < .001, r = 0.70), VCO2 and tidal volume (P < .001, r = 0.70), and VCO2 and body temperature (P < .001, r = 0.41). Fifteen (14.6%) of the 103 patients died within 4 months after the operation without having been discharged from hospital. Baseline VO2/BSA was higher in surviving patients (123.7 ± 23.6 mL/min ∙ m(2)) than the deceased (103.8 ± 15.6 mL/min ∙ m(2); P = .002). There was no significant difference in baseline VCO2/BSA levels between surviving (106.2 ± 20.1 mL/min ∙ m(2)) and deceased patients (99.4 ± 21.4 mL/min ∙ m(2)). In multivariate analysis, baseline body temperature lower than 36.2°C (P = .02), serum albumin less than 3.0 g/dL (P = .002), and baseline VO2/BSA less than 111.9 mL/min ∙ m(2) (P = .03) were independent factors. Baseline low VO2/BSA less than 111.9 mL/min ∙ m(2) was one of the poor predictors for the prognosis of an emergency open abdominal surgery. Copyright © 2015 Elsevier Inc. All rights reserved.

AIMS Serum chemerin concentrations are elevated in obese individuals and may play a role in type 2 diabetes. Exercise improves insulin sensitivity, which may be related to changes in chemerin. This study explored how an acute bout of aerobic exercise affected chemerin levels in non-diabetic obese adults. METHODS Blood samples from 11 obese adults were obtained during two separate conditions: sedentary (SED) and exercise (EX; 60-65% VO2peak). Samples were drawn at baseline, immediately following exercise and hourly for an additional 2 hours. ANOVA was used to test for differences in chemerin between conditions. RESULTS Unadjusted analysis showed no difference in overall change (baseline to 2 hrs post) in chemerin between conditions. During the 2-hr post-exercise period, chemerin decreased to 12% below baseline, compared to a 2.5% increase above baseline during that time period on the sedentary day (p=0.06, difference in post-to-2hr change between conditions). Controlling for homeostatic model assessment of insulin resistance (HOMA-IR), a significant difference existed between EX and SED in the change in chemerin from baseline to 2-hr post (p=0.02). Stratified analyses showed a consistent exercise-induced decrease in chemerin among non-insulin resistant subjects, while chemerin increased during exercise among insulin resistant subjects, and then decreased post-exercise. CONCLUSION An acute bout of exercise in obese individuals may elicit a drop in chemerin levels during the post-exercise period, and this response may vary based on insulin resistance. PMID:26008676

Men who are violent toward their partners tend to have a dual problem with alcohol and drug use, yet little is known about differences between men with single rather than dual problems. This study was one of the first to evaluate differences between alcohol dependent men who were arrested for Intimate Partner Violence (IPV) with and without concurrent illicit drug use. Seventy-eight participants were randomly assigned to manual-guided group behavioral therapies (Cognitive Behavioral Therapy or Twelve Step Facilitation) and assessed across 12 weeks of treatment. Despite denying drug use at baseline, thirty-two clients (43%) tested positive for illicit drug use (cocaine and marijuana) during the 12 weeks of treatment. The study specifically addressed whether there were differences between clients using alcohol only versus individuals using both alcohol + drugs in terms of 1) baseline characteristics; 2) treatment compliance (e.g., attendance and substance use during treatment; and 3) treatment outcomes (alcohol, drug use, anger management, and aggression at the completion of treatment). The results showed that there were comparatively few differences between the alcohol versus the alcohol + drug using groups at baseline. Regarding treatment compliance and retention, alcohol + drug using participants attended significantly fewer sessions, had significantly fewer percent days abstinence from alcohol use, significantly more total days of positive breathalyzer results. Regarding treatment outcomes across anger management and aggression scores, the alcohol + drug using participants had significantly more impairments in anger management styles from pre- to post-treatment. However, there were no differences between the groups across verbal or physical aggression. Both groups improved in their verbal aggression from pre- to post-treatment. The findings suggest that alcohol dependent men who continue to use illicit drugs may require additional interventions to effectively control their drug use and, their anger management styles.

Improvements in data quality for the mobile VLBI systems have placed higher accuracy requirements on Earth orientation calibrations. Errors in these calibrations may give rise to systematic effects in the nonlength components of the baselines. Various sources of Earth orientation data were investigated for calibration of Mobile VLBI baselines. Significant differences in quality between the several available sources of UT1-UTC were found. It was shown that the JPL Kalman filtered space technology data were at least as good as any other and adequate to the needs of current Mobile VLBI systems and observing plans. For polar motion, the values from all service suffice. The effect of Earth orientation errors on the accuracy of differenced baselines was also investigated. It is shown that the effect is negligible for the current mobile systems and observing plan.

Presently the necessity of fasting time for coagulation tests is not standardized. Our hypothesis is that this can harm patient safety. This study is aimed at evaluating whether a light meal (i.e. breakfast) can jeopardize laboratory coagulation tests. A blood sample was firstly collected from 17 fasting volunteers (12 h). Immediately after blood collection, the volunteers consumed a light meal. Then samples were collected at 1, 2 and 4 h after the meal. Coagulation tests included: activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen (Fbg), antithrombin III (AT), protein C (PC) and protein S (PS). Differences between samples were assessed by Wilcoxon ranked-pairs test. The level of statistical significance was set at P < 0.05. Mean % differences were determined and differences between and baseline and 1, 2 and 4h samples were compared with reference change value (RCV). A significantly higher % activity of AT was observed at 1 h and 4 h after meal vs. baseline specimen [113 (104-117) and 111 (107-120) vs. 109 (102-118), respectively; P = 0.029 and P = 0.016]. APTT at 2 h was found significantly lower than baseline samples [32.0 (29.9-34.8) vs. 34.1 (32.2-35.2), respectively; P = 0.041]. The results of both Fbg and PS tests were not influenced by a light meal. Furthermore, no coagulation tests had significant variation after comparison with RCV. A light meal does not influence the laboratory coagulation tests we assessed, but we suggest that the laboratory quality managers standardize the fasting time for all blood tests at 12 hours, to completely metabolize the lipids intake.

We examined the relationship between socioeconomic status (SES) and course and outcome of patients with psychosis. Two hypotheses were examined: a) patients with higher best-ever SES will have better course and outcome than those with lower best-ever SES, and b) patients with greater downward drift in SES will have poorer course and outcome than those with less downward drift. Data were drawn from the baseline and 2-year follow-up assessments of the UK700 Case Management Trial of 708 patients with severe psychosis. The indicators of SES used were occupational status and educational achievement. Drift in SES was defined as change from best-ever occupation to occupation at baseline. For the baseline data highly significant differences were found between best-ever groups and negative symptoms (non-manual vs. unemployed--coef -10.5, p=0.000, 95% CIs 5.1-15.8), functioning (non-manual vs. unemployed--coef -0.6, p=0.000, 95% CIs 0.3 to -0.8) and unmet needs (manual vs. unemployed - coef 0.5, p=0.004, 95% CIs 0.2-0.9). No significant differences between best-ever groups were found for days in hospital, symptoms, perceived quality of life and dissatisfaction with services. Significant differences for clinical and social variables were found between drift and non-drift SES groups. There were no significant findings between educational groups and clinical and social variables. Best-ever occupation, but not educational qualifications, appeared to predict prognosis in patients with severe psychosis. Downward drift in occupational status did not result in poorer illness course and outcome.

Previous cross-sectional studies and 6-year longitudinal study have demonstrated that home blood pressure (HBP) measurements upon awakening have a stronger predictive power for death, micro- and macrovascular complications than clinic blood pressure (CBP) measurements in patients with type 2 diabetes (T2DM). This study investigated which of these measurements offers stronger predictive power for outcomes over 10 years. At baseline, 400 Japanese patients with T2DM were classified as having hypertension (HT) or normotension (NT) based on HBP and CBP. The mean survey duration was 95 months. Primary and secondary end-points were death and new or worsened micro- and macrovascular complications, respectively. Differences in outcomes for each end-point between HT and NT patients were analyzed using Kaplan-Meier survival curves and log-rank testing. Associated risk factors were assessed using Cox proportional hazards analysis. Based on HBP, death and micro- and macrovascular complications were significantly higher in patients with HT than with NT at baseline and end-point. Based on CBP, there were no significant differences in incidence of death, micro- or macrovascular complications between patients with HT and NT at baseline and end-point, although a significant difference in incidence of death was observed between the HT and NT groups at end-point. However, the significance was significantly lower in CBP than in HBP. One risk factor associated with micro- and macrovascular complications in patients with HBP was therapy for HT. This 10-year longitudinal study of patients with T2DM demonstrated that elevated HBP upon awakening is predictive of death, and micro- and macrovascular complications.

Darifenacin and trospium are the commonly used antimuscarinics in the management of overactive bladder (OAB). Constipation is the second most common treatment related side-effect. Though its incidence with the above two medications is known, data on their comparative severity and impact on patient's well-being is lacking. Sixty subjects with OAB included in the study were randomized in 1:1 fashion to receive either darifenacin 7.5 mg OD or trospium extended release 60 mg OD. Treatment response was monitored using overactive bladder symptom score (OABSS). The severity of constipation was assessed using McMillan & Williams Constipation assessment scale (CAS), Bristol stool form scale and Knowles-Eccersley-Scott-Symptom (KESS) questionnaire score administered at baseline, 2 and 4 weeks of treatment. OABSS improved significantly, -5.80 ± 3.99 (p = 0.0005) and -5.27 ± 2.98 (p = 0.0005) in darifenacin and trospium groups respectively. However, the difference between the two groups was not significant either at 2 weeks (p = 0.952) or 4 weeks (p = 0.654) of treatment. A significant decrease in stool consistency was noted with darifenacin treatment (p < 0.05), but the same was not seen with trospium (p = 0.076). There was no significant difference in scores of KESS questionnaire between baseline, 2 weeks and 4 weeks, both within the group and between the groups (p > 0.05). McMillan & Williams CAS scores increased at week 2 and week 4, in comparison with baseline scores in both darifenacin and trospium treated patients, however, the difference between the two groups was not statistically significant (p > 0.05). Darifenacin and trospium are equally efficacious and comparable in tolerability in terms of constipation severity and its impact on patient well-being.

Purpose The NCIC CTG PR3/MRC PR07 randomized phase III trial compared androgen-deprivation therapy (ADT) alone versus ADT with radiotherapy (RT) for patients with locally advanced prostate cancer. This article reports the health-related quality-of-life (HRQOL) outcomes of this trial. Patients and Methods A total of 1,205 patients were randomly allocated to either ADT alone or ADT with RT. HRQOL was assessed at baseline and every 6 months thereafter using the European Organisation for Research and Treatment of Cancer Core Questionnaire and a prostate cancer–specific checklist or the Functional Assessment of Cancer Therapy–Prostate questionnaire. Mean changes from baseline scores for five function domains and nine symptom domains were analyzed as those most relevant to ADT and RT. The proportions of patients with improved, stable, or worsened HRQOL scores according to instrument-specific minimal important differences were calculated. Results Baseline questionnaires were completed by 1,028 patients (88%). At 6 months, RT had a statistically significant impact on mean score for bowel symptoms (P = .02), diarrhea (P < .001), urinary function (P = .003), and erectile dysfunction (P = .008); by 3 years, however, there were no significant between-group differences in any domain. Generalized linear mixed modeling revealed no significant between-arm differences in any of the function scales but showed significant deterioration in both arms over time for Functional Assessment of Cancer Therapy–Prostate total score, treatment outcome index, and physical and functional well-being. Conclusion The addition of RT to ADT for patients with locally advanced prostate cancer significantly improved overall survival and had only modest and transient negative impact on relevant domains of HRQOL.

To clarify the impact of hearing aids on mental health, social engagement, cognitive function, and physical health outcomes in older adults with hearing impairment. We assessed hearing handicap (hearing handicap inventory for the elderly; HHIE-S), cognition (mini mental state exam, trail making, auditory verbal learning, digit-symbol substitution, verbal fluency, incidence of cognitive impairment), physical health (SF-12 physical component, basic and instrumental activities of daily living, mortality), social engagement (hours per week spent in solitary activities), and mental health (SF-12 mental component) at baseline, five years prior to baseline, and five and 11 years after baseline. Community-dwelling older adults with hearing impairment (N = 666) from the epidemiology of hearing loss study cohort. There were no significant differences between hearing-aid users and non-users in cognitive, social engagement, or mental health outcomes at any time point. Aided HHIE-S was significantly better than unaided HHIE-S. At 11 years hearing-aid users had significantly better SF-12 physical health scores (46.2 versus 41.2; p = 0.03). There was no difference in incidence of cognitive impairment or mortality. There was no evidence that hearing aids promote cognitive function, mental health, or social engagement. Hearing aids may reduce hearing handicap and promote better physical health.

Aim: To investigate a potential association between SNP rs10494366 in the neural nitric oxide synthase adaptor protein (NOS1AP) and efficacy of repaglinide (an insulin secretagogue) in newly diagnosed Shanghai Chinese type 2 diabetes patients. Methods: A total of 104 newly diagnosed type 2 diabetes patients (69 men, 35 women) were recruited and treated with repaglinide for 24 weeks. Anthropometric measurements, clinical laboratory tests were obtained at baseline and after 24-week treatment. Genotyping was performed by sequencing. Results: The baseline value of BMI, HOMA-IR, HOMA-B, and fasting insulin level were significantly different between GG, GT, and TT genotypes (P=0.024, 0.030, 0.005, and 0.007, respectively). Carriers of TT genotype were in significant insulin resistance at baseline. After 24-week repaglinide monotherapy, the Δ value of fasting insulin (P=0.019) and HOMA-IR (P=0.011) were significantly different. TT carriers had the least insulin resistance after treatment. The mixed model analysis showed that the variation had an interaction effect with repaglinide treatment only on HOMA-IR (P=0.013). Conclusion: A common variant in rs10494366 is associated with repaglinide monotherapy efficacy on insulin resistance in newly diagnosed Shanghai Chinese type 2 diabetes patients. PMID:20305679

To determine the effects of povidone iodine 5% (Betadine 5%) applied to the eye on visual function, corneal integrity, and subjective complaints. Ten subjects were chosen to participate in this study (average age 40.6 ± 19.6; age range 22-68). LogMAR acuity, contrast sensitivity, corneal fluorescein staining, and subjective complaints were measured before and after 60 μl of Betadine 5% or saline were applied to one eye (eligibility visit, baseline, 5, 30, and 60 minutes and 4 and 24 hours post-application). Contrast sensitivity at 14 cpd was determined with a spatial two-alternative, forced choice procedure (Beethoven software). The National Eye Institute (NEI) grid pattern was used to grade corneal staining with sodium fluorescein. To avoid the detrimental effects of sodium fluorescein administration on functional vision, the corneal staining baseline was measured at the eligibility visit. Subjective complaints were monitored using the Schein dry eye questionnaire. The data were analyzed with an ANOVA. Saline administration did not alter logMAR acuity, contrast sensitivity, corneal fluorescein staining, or subjective complaints at any visit. Betadine administration significantly reduced the logMAR acuity, compared to baseline and the saline data, at the 30- and 60-minute visits (all P values <.05). The contrast sensitivity was significantly reduced compared to the baseline and the saline results at 5, 30, and 60 minutes after Betadine application (all P values <.05). The Betadine significantly increased the Schein questionnaire score, compared both to baseline and the saline data, at the 1- and 4-hour visits (all P values <.05). Total corneal staining and the maximum NEI sector staining were significantly different from baseline and from the saline results at every visit (all P values <.05). Betadine 5% application significantly decreases epithelial integrity of the cornea, decreases functional vision, and increases subjective complaints.

To examine the psychosocial outcomes and impact of attention problems in survivors of pediatric brain tumor. The survivors' cognitive functioning was measured using the Wechsler Intelligence Scale for Children. The Child Behavior Checklist-Attention Problems scale was used to screen for attention problems, and participants were classified as having attention problems (n=15) or normal attention (n=36). Psychosocial functioning was examined with the Korean Personality Rating scale for Children (K-PRC) at precraniospinal radiation and at 2-year follow-up. The attention problem group showed significantly higher depression and externalizing symptoms (delinquency, hyperactivity) and more significant impairment in family relationships than did the normal attention group at baseline. At follow-up, the attention problem group demonstrated significantly more delinquency and impaired family and social relationships. With the K-PRC scores, except for the somatization, social relationship subscale, there were significant differences between groups, but not in terms of treatment by time interaction or within time. At follow-up, multiple linear regressions showed that age at diagnosis significantly predicted K-PRC somatization (B=-1.7, P=0.004) and social relationships (B=-1.7, P=0.004), baseline full-scale intelligence quotient predicted K-PRC depression (B=-0.4, P=0.032) and somatization (B=-0.3, P=0.015), and attention problems at baseline predicted K-PRC depression (B=-15.2, P=0.036) and social relationships (B=-11.6, P=0.016). Pediatric brain tumor survivors, in particular, patients with attention problems, had worse psychosocial functioning at baseline and follow-up. Attention problems at baseline need to be carefully evaluated in assessing psychosocial functioning of pediatric brain tumor survivors.

Our objectives were to (1) investigate the feasibility of the use of the Japanese version of the Hopkins Verbal Learning Test-Revised (HVLT-R); (2) identify the clinical factors influencing the HVLT-R scores of patients undergoing whole-brain radiation therapy (WBRT); and (3) compare the neurocognitive function (NCF) after WBRT in different dose fractionation schedules. We administered the HVLT-R (Japanese version) before (baseline) and at four and eight months after WBRT in 45 patients who received either therapeutic (35Gy-in-14, n = 16; 30Gy-in-10, n = 18) or prophylactic (25Gy-in-10, n = 11) WBRT. Sixteen patients dropped out before the eight-month examination, due mostly to death from cancer. The Karnofsky Performance Status (KPS) 80–100 group had significantly higher baseline total recall (TR) scores (p = 0.0053), delayed recall (DR) scores (p = 0.012), and delayed recognition (DRecog) scores (p = 0.0078). The patients aged ≤65 years also had significantly higher TR scores (p = 0.030) and DRecog scores (p = 0.031). The patients who underwent two examinations (worse-prognosis group) had significantly decreased DR scores four months after WBRT compared to the baseline (p = 0.0073), and they were significantly more likely to have declined individual TR scores (p = 0.0017) and DR scores (p = 0.035) at four months. The eight-month HVLT-R scores did not significantly decline regardless of the WBRT dose fractionation. The baseline NCF was determined by age and KPS, and the early decline in NCF is characteristic of the worse-prognosis group. PMID:27827891

There is no agreement on the systematic exploration of the fundus oculi (FO) in hypertensive patients, and it is unknown whether the evolution of retinal microcirculatory alterations has prognostic value or not. The aim of this study was to investigate whether the evolution of the arteriole-to-venule ratio (AVR) in newly-diagnosed hypertensive patients is associated with better or worse evolution of target organ damage (TOD) during 1 year. A cohort of 133 patients with newly-diagnosed untreated hypertension was followed for 1 year. At baseline and follow-up, all patients underwent a physical examination, self-blood pressure measurement, ambulatory blood pressure monitoring, blood and urine analysis, electrocardiogram, and retinography. The endpoint was the favourable evolution of TOD and the total amount of TOD, according to the baseline AVR and the baseline and final difference of the AVR. A total of 133 patients were analyzed (mean age, 57 ± 10.7 years; 59% men). No differences were found in the decrease in blood pressure or antihypertensive treatment between quartiles of baseline AVR or baseline-final AVR difference. Patients with a difference between baseline and final AVR in the highest quartile (>0.0817) had a favorable evolution of left ventricular hypertrophy (odds ratio, 14.9; 95% confidence interval, 1.08-206.8) and the amount of TOD (odds ratio, 2.22; 95% confidence interval, 1.03-6.05). No favorable evolution was found of glomerular filtration rate. There is an association between the evolution of the AVR and the favorable evolution of TOD. Patients with greater increase of AVR have significantly better evolution of left ventricular hypertrophy and amount of TOD. Copyright © 2014 American Society of Hypertension.

Background and Purpose Sex and race reportedly influence outcome after recombinant tissue-type plasminogen activator (rtPA). It is, however, unclear whether baseline imbalances (eg, stroke severity) or lack of response to thrombolysis is responsible. We applied balancing methods to test the hypothesis that race and sex influence outcome after rtPA independent of baseline conditions. Methods We mapped group outcomes from the National Institute of Neurological Disorders and Stroke (NINDS) dataset based on race and sex onto a surrogate-control function to assess differences from expected outcomes at their respective National Institutes of Health Stroke Scale and age. Outcomes were also compared for subjects matched individually on key baseline factors using NINDS and 2 recent datasets from southeastern United States. Results At similar National Institutes of Health Stroke Scale and age, 90-day good outcomes (modified Rankin Score, 0–2) in NINDS were similarly improved after rtPA for white men and women. There was a strong trend for improvement in black men. Conversely, black women treated with rtPA showed response rates no different from the controls. After baseline matching, there were nonsignificant trends in outcomes except for significantly fewer good outcomes in black versus matched white women (37% versus 63%; P=0.027). Pooling the 3 datasets showed a similar trend for poorer short-term outcome for black women (P=0.054; modified Rankin Score, 0–1). Conclusions Matching for key baseline factors indicated that race and sex influence outcome most strikingly in black women who demonstrated poorest outcomes after rtPA. This finding supports the hypothesis that poor response to rtPA, rather than differences in baseline conditions, contributes to the worse outcome. This finding requires prospective confirmation.

Estrogen receptors are present in thyroid follicular cells in normal and neoplastic tissue. We evaluated changes in total thyroid volume and volume of thyroid nodules in postmenopausal women given either hormone therapy (HT) or no treatment in a 1-year observational follow-up. We studied 33 women receiving HT and 76 women receiving no treatment, comparing total thyroid volume, thyroid nodule volume, and serum concentrations of thyroid-stimulating hormone and estradiol at baseline and 1 year of follow-up. Serum thyroid-stimulating hormone concentrations were not different between groups either at baseline or at 1 year. Estradiol rose significantly in the HT group. The final percent changes in total thyroid volume were comparable between groups (HT, 1.59 +/- 2.56%; no treatment, 1.20 +/- 2.28%). At baseline, nodules were detected in 17 (51.5%) and 33 (43.4%) of women in the HT and no treatment groups, respectively, with no statistically significant difference between groups. The final number of nodules was unchanged or reduced in 88.2% and 81.1% and increased in 11.8% and 18.9% of women in the HT and no treatment groups, respectively, with no differences between groups. Baseline volumes of thyroid nodules were 0.8 +/- 0.4 and 1.4 +/- 0.4 mL in women in the HT and no treatment groups, respectively (P = 0.4). After 1 year the volume of thyroid nodules was unchanged or reduced in 47.1% and 52.8% and increased in 52.9% and 47.2% of women in the HT and no treatment groups, respectively, with no differences between groups. Estrogen administration for 1 year did not affect thyroid volume or the number and volume of thyroid nodules in postmenopausal women.

To determine whether characteristics and outcomes of Italian patients in the observational global Hypopituitary Control and Complication Study (HypoCCS) differed according to the degree of GH deficiency (GHD). Patients were grouped by tertiles of stimulated GH peak concentration at baseline (Group A lowest tertile, n = 342; Group B middle tertile, n = 345; Group C highest tertile, n = 338). Baseline demographics, lipid levels, body mass index categories and mean Framingham cardiovascular risk indexes were similar in the three groups and remained substantially unchanged over time, with no subsequent significant between-group differences (except mean levels of triglycerides increased in the highest tertile group). GHD was adult-onset for >75% of patients in all groups. The percentage of patients with multiple pituitary deficiencies was higher in Group A than in the other groups; isolated GHD was reported with highest frequency in Group C. Patients in Group A received the lowest mean starting dose of GH. Hyperlipidaemia at baseline was reported in 35·1%, 31·1% and 24·7% of patients in groups A, B and C, respectively (P = 0·029). Mean duration of GH treatment was 7·21, 5·45 and 4·96 years, respectively. The proportion of patients with adverse events did not differ significantly between groups, with a low prevalence over time of diabetes and cancer. In Italian patients from HypoCCS, the level of GH deficit did not influence changes over time in metabolic parameters or adverse event profile, despite differences in GHD severity at baseline and in the starting GH dose. © 2015 John Wiley & Sons Ltd.

Higher concentrations of certain phthalate metabolites are associated with adverse reproductive and pregnancy outcomes, as well as poor infant/child health outcomes. In non-pregnant populations, phthalate metabolite concentrations vary by race/ethnicity. Few studies have documented racial/ethnic differences between phthalate metabolite concentrations at multiple time points across the full-course of pregnancy. The objective of the study was to characterize the change in phthalate metabolite concentrations by race/ethnicity across multiple pregnancy time points. Women were participants in a prospectively collected pregnancy cohort who delivered at term (≥37 weeks) and had available urinary phthalate metabolite concentrations for ≥3 time points across full-term pregnancies (n=350 women). We assessed urinary concentrations of eight phthalate metabolites that were log-transformed and specific gravity-adjusted. We evaluated the potential racial/ethnic differences in phthalate metabolite concentrations at baseline (median 10 weeks gestation) using ANOVA and across pregnancy using linear mixed models to calculate the percent change and 95% confidence intervals adjusted for sociodemographic and lifestyle factors. Almost 30% of the population were non-Hispanic black or Hispanic. With the exception of mono-(3-carboxypropyl) (MCPP) and di-ethylhexyl phthalate (DEHP) metabolites, baseline levels of phthalate metabolites were significantly higher in non-whites (P<0.05). When evaluating patterns by race/ethnicity, mono-ethyl phthalate (MEP) and MCPP had significant percent changes across pregnancy. MEP was higher in Hispanics at baseline and decreased in mid-pregnancy but increased in late pregnancy for non-Hispanic blacks. MCPP was substantially higher in non-Hispanic blacks at baseline but decreased later in pregnancy. Across pregnancy, non-Hispanic black and Hispanic women had higher concentrations of certain phthalate metabolites. These differences may have implications for racial/ethnic differences in adverse pregnancy and child health outcomes.

MicroRNAs are short, non-coding molecules that regulate gene expression. Here, we investigate the role of microRNAs in depression and electroconvulsive therapy (ECT). We performed three studies: a deep sequencing discovery-phase study of miRNA changes in whole blood following ECT (n = 16), followed by a validation study in a separate cohort of patients pre-/post-ECT (n = 37) and matched healthy controls (n = 34). Changes in an experimentally validated gene target (VEGFA) were then analysed in patients pre-/post-ECT (n = 97) and in matched healthy controls (n = 53). In the discovery-phase study, we found no statistically significant differences in miRNA expression from baseline to end of treatment in the group as a whole, but post hoc analysis indicated a difference in patients with psychotic depression (n = 3). In a follow-up validation study, patients with psychotic depression (n = 7) had elevated baseline levels of miR-126-3p (t = 3.015, P = 0.006) and miR-106a-5p (t = 2.598, P = 0.025) compared to healthy controls. Following ECT, these differences disappeared. Baseline VEGFA levels were significantly higher in depressed patients compared to healthy controls (F(1,144) = 27.688, P = <0.001). Following ECT, there was a significant change in VEGFA levels in the psychotic group only (t = 2.915, P = 0.010). Molecular differences (miRNA and VEGFA) may exist between psychotic and non-psychotic depression treated with ECT. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

African-Americans (AA) have increased carotid artery intima-media thickness and decreased vascular function compared to their Caucasian (CA) peers. Aerobic exercise prevents and potentially reverses arterial dysfunction. Purpose The purpose of this study was to examine the effect of 8 weeks of moderate-high intensity aerobic training in young healthy sedentary AA and CA men and women. Methods Sixty-four healthy volunteers (men = 28, women = 36) with mean age = 24 underwent measures of arterial structure, function and blood pressure variables at baseline, post-4 week control period and 8 weeks post-training. Results There was a significant increase in VO2peak amongst both groups post exercise training. Brachial systolic blood pressure decreased significantly following control period in both groups but not following exercise training. Carotid pulse pressure decreased significantly in both groups post exercise training as compared to baseline. There was no change in any of the other blood pressure variables. AAs had a higher intima-media thickness at baseline and post-control period, but significantly decreased following exercise training compared to CAs. AAs had significantly lower baseline forearm blood flow and RH compared to CAs, but exercise training had no effect on these variables. There was no significant difference in arterial stiffness (cPWV) and wave-reflection (AIx) between the two groups at any time point. Conclusions This is the first study to show that, 8 weeks of aerobic exercise training causes significant improvement in the arterial structure in young, healthy AAs, making it comparable to the CAs and with minimal effects on blood pressure variables.

African Americans (AA) have increased carotid artery intima-media thickness and decreased vascular function compared with their Caucasian (CA) peers. Aerobic exercise prevents and potentially reverses arterial dysfunction. The purpose of this study was to examine the effect of 8 wk of moderate- to high-intensity aerobic training in young healthy sedentary AA and CA men and women. Sixty-four healthy volunteers (men, 28; women, 36) with mean age 24 yr underwent measures of arterial structure, function, and blood pressure (BP) variables at baseline, after the 4-wk control period, and 8 wk after training. There was a significant increase in VO2peak among both groups after exercise training. Brachial systolic BP decreased significantly after the control period in both groups but not after exercise training. Carotid pulse pressure decreased significantly in both groups after exercise training as compared with that in baseline. There was no change in any of the other BP variables. AA had higher intima-media thickness at baseline and after the control period but it significantly decreased after exercise training compared with that of CA. AA had significantly lower baseline forearm blood flow and reactive hyperemia compared with those of CA, but exercise training had no effect on these variables. There was no significant difference in arterial stiffness (central pulse wave velocity) and wave-reflection (augmentation index) between the two groups at any time point. This is the first study to show that 8 wk of aerobic exercise training causes significant improvement in the arterial structure in young, healthy AA, making it comparable with the CA and with minimal effects on BP variables.

Background Physical activity tracking wearable devices have emerged as an increasingly popular method for consumers to assess their daily activity and calories expended. However, whether these wearable devices are valid at different levels of exercise intensity is unknown. Objective The objective of this study was to examine heart rate (HR) and energy expenditure (EE) validity of 3 popular wrist-worn activity monitors at different exercise intensities. Methods A total of 62 participants (females: 58%, 36/62; nonwhite: 47% [13/62 Hispanic, 8/62 Asian, 7/62 black/ African American, 1/62 other]) wore the Apple Watch, Fitbit Charge HR, and Garmin Forerunner 225. Validity was assessed using 2 criterion devices: HR chest strap and a metabolic cart. Participants completed a 10-minute seated baseline assessment; separate 4-minute stages of light-, moderate-, and vigorous-intensity treadmill exercises; and a 10-minute seated recovery period. Data from devices were compared with each criterion via two-way repeated-measures analysis of variance and Bland-Altman analysis. Differences are expressed in mean absolute percentage error (MAPE). Results For the Apple Watch, HR MAPE was between 1.14% and 6.70%. HR was not significantly different at the start (P=.78), during baseline (P=.76), or vigorous intensity (P=.84); lower HR readings were measured during light intensity (P=.03), moderate intensity (P=.001), and recovery (P=.004). EE MAPE was between 14.07% and 210.84%. The device measured higher EE at all stages (P<.01). For the Fitbit device, the HR MAPE was between 2.38% and 16.99%. HR was not significantly different at the start (P=.67) or during moderate intensity (P=.34); lower HR readings were measured during baseline, vigorous intensity, and recovery (P<.001) and higher HR during light intensity (P<.001). EE MAPE was between 16.85% and 84.98%. The device measured higher EE at baseline (P=.003), light intensity (P<.001), and moderate intensity (P=.001). EE was not significantly different at vigorous (P=.70) or recovery (P=.10). For Garmin Forerunner 225, HR MAPE was between 7.87% and 24.38%. HR was not significantly different at vigorous intensity (P=.35). The device measured higher HR readings at start, baseline, light intensity, moderate intensity (P<.001), and recovery (P=.04). EE MAPE was between 30.77% and 155.05%. The device measured higher EE at all stages (P<.001). Conclusions This study provides one of the first validation assessments for the Fitbit Charge HR, Apple Watch, and Garmin Forerunner 225. An advantage and novel approach of the study is the examination of HR and EE at specific physical activity intensities. Establishing validity of wearable devices is of particular interest as these devices are being used in weight loss interventions and could impact findings. Future research should investigate why differences between exercise intensities and the devices exist. PMID:28302596

In 2008, the Irish Government initiated a pilot Healthy Schools Programme based on the World Health Organization Health Promoting Schools Model among children attending schools officially designated as urban and disadvantaged. We present here the first results on physical and emotional health and the relationship between childhood depression and demographic and socioeconomic factors. The Healthy Schools Programme evaluation was a 3-year longitudinal outcome study among urban disadvantaged children aged 4 to 12 years. Physical and psychological health outcomes were measured using validated, international instruments at baseline. Outcomes at baseline were compared with international norms and where differences were found, results were statistically modeled to determine factors predicting poor outcomes. A total of 552 children responded at baseline, representing over 50% of all eligible children available to participate from 7 schools. Findings at baseline revealed that in general, children did not differ significantly from international norms. However, detailed analysis of the childhood depression scores revealed that in order of importance, psychological well-being, the school environment, social support, and peer relations and age were statistically significant predictors of increased childhood depression in children under 12 years of age. Future health and well-being studies in schools among urban disadvantaged children need to broaden their scope to include measures of depression in children under 12 years of age and be cognisant of the impact of the school environment on the mental and emotional health of the very young. © 2012, American School Health Association.

Rationale Anxiety and aggression are associated with ethanol self-administration, but these behaviors can serve as either risk factors for or consequences of heavy drinking in rodents and humans. Baseline levels of aggressive-like and anxious-like behavior in non-human primates have not yet been characterized in relation to future or prior ethanol intake. Objective To test the association between temperament at baseline with future ethanol self-administration in late adolescent male (n=21) and female (n=11) rhesus monkeys. Methods Shortly after entering the laboratory and before exposure to ethanol, the Human Intruder Test (HIT) and the Novel Object Test (NOT) were used to determine baseline anxious-like and aggressive-like behavior in age-matched male and female rhesus monkeys (Macaca mulatta). The monkeys were induced to drink ethanol 4% (w/v) using a schedule-induced polydipsia procedure, followed by “open-access” ethanol self-administration in which the monkeys were allowed a choice of water or 4% ethanol (w/v) for 22 hours/day (h/d) for 52 weeks. Results Aggressive monkeys self-administered more ethanol and attained higher Blood Ethanol Concentrations (BECs). No significant differences in ethanol intakes or BECs were found between anxious and non-anxious monkeys or between behaviorally inhibited and non-inhibited monkeys. Baseline aggressive behavior positively correlated with ethanol intake and intoxication. Conclusions Baseline reactive aggression was associated with higher future ethanol intake and intoxication. While significant sex differences in HIT reactivity were observed, the relationship between aggression and ethanol drinking was observed across sex and is not sex-specific. PMID:27627910

Graduate healthcare students experience significant stressors during professional training. Mindfulness-Based Stress Reduction (MBSR) is a behavioural intervention designed to teach self-regulatory skills for stress reduction and emotion management. This study examines the impact of MBSR training on students from five healthcare graduate programs in a quasi-experimental trial. A total of 13 students completed the MBSR program and were compared with 15 controls. Both groups answered validated questionnaires measuring anxiety, burnout and empathy at baseline, at conclusion of the course (week 8) and 3 weeks post-course completion (week 11). Significant decrease in anxiety at weeks 8 and 11 compared with baseline (P<0.001 and P<0.01, respectively) was observed using the Burns Anxiety Inventory. Significant increase in empathy at week 8 (P<0.0096) was observed using the Jefferson Scale of Physician Empathy. Week 11 demonstrated a decrease in empathy from baseline (not statistically significant) across all subjects. No significant differences in burnout scores at weeks 8 and 11 were observed between those in the intervention and control groups. These results provide supportive evidence of MBSR as a behavioural intervention to reduce anxiety and increase empathy among graduate healthcare students.

Studies of physical exercise in patients with Alzheimer's disease (AD) are few and results have been inconsistent. To assess the effects of a moderate-to-high intensity aerobic exercise program in patients with mild AD. In a randomized controlled trial, we recruited 200 patients with mild AD to a supervised exercise group (60-min sessions three times a week for 16 weeks) or to a control group. Primary outcome was changed from baseline in cognitive performance estimated by Symbol Digit Modalities Test (SDMT) in the intention-to-treat (ITT) group. Secondary outcomes included changes in quality of life, ability to perform activities of daily living, and in neuropsychiatric and depressive symptoms. The ITT analysis showed no significant differences between intervention and control groups in change from baseline of SDMT, other cognitive tests, quality of life, or activities of daily living. The change from baseline in Neuropsychiatric Inventory differed significantly in favor of the intervention group (mean: -3.5, 95% confidence interval (CI) -5.8 to -1.3, p = 0.002). In subjects who adhered to the protocol, we found a significant effect on change from baseline in SDMT as compared with the control group (mean: 4.2, 95% CI 0.5 to 7.9, p = 0.028), suggesting a dose-response relationship between exercise and cognition. This is the first randomized controlled trial with supervised moderate-to-high intensity exercise in patients with mild AD. Exercise reduced neuropsychiatric symptoms in patients with mild AD, with possible additional benefits of preserved cognition in a subgroup of patients exercising with high attendance and intensity.

Abstract Objective This prospective, randomized, split-mouth clinical trial evaluated the clinical performance of conventional glass ionomer cement (GIC; Riva Self-Cure, SDI), supplied in capsules or in powder/liquid kits and placed in Class I cavities in permanent molars by the Atraumatic Restorative Treatment (ART) approach. Material and Methods A total of 80 restorations were randomly placed in 40 patients aged 11-15 years. Each patient received one restoration with each type of GIC. The restorations were evaluated after periods of 15 days (baseline), 6 months, and 1 year, according to ART criteria. Wilcoxon matched pairs, multivariate logistic regression, and Gehan-Wilcoxon tests were used for statistical analysis. Results Patients were evaluated after 15 days (n=40), 6 months (n=34), and 1 year (n=29). Encapsulated GICs showed significantly superior clinical performance compared with hand-mixed GICs at baseline (p=0.017), 6 months (p=0.001), and 1 year (p=0.026). For hand-mixed GIC, a statistically significant difference was only observed over the period of baseline to 1 year (p=0.001). Encapsulated GIC presented statistically significant differences for the following periods: 6 months to 1 year (p=0.028) and baseline to 1 year (p=0.002). Encapsulated GIC presented superior cumulative survival rate than hand-mixed GIC over one year. Importantly, both GICs exhibited decreased survival over time. Conclusions Encapsulated GIC promoted better ART performance, with an annual failure rate of 24%; in contrast, hand-mixed GIC demonstrated a failure rate of 42%. PMID:29364343

There is limited evidence about the distinguished effect of 3D oral health education videos over conventional 2 dimensional projections in improving oral health knowledge. This randomized controlled trial was done to test the effect of 3 dimensional oral health educational videos among first year dental students. 80 first year dental students were enrolled and divided into two groups (test and control). In the test group, 3D animation and in the control group, regular 2D video projections pertaining to periodontal anatomy, etiology, presenting conditions, preventive measures and treatment of periodontal problems were shown. Effect of 3D animation was evaluated by using a questionnaire consisting of 10 multiple choice questions given to all participants at baseline, immediately after and 1month after the intervention. Clinical parameters like Plaque Index (PI), Gingival Bleeding Index (GBI), and Oral Hygiene Index Simplified (OHI-S) were measured at baseline and 1 month follow up. A significant difference in the post intervention knowledge scores was found between the groups as assessed by unpaired t-test (p<0.001) at baseline, immediate and after 1 month. At baseline, all the clinical parameters in the both the groups were similar and showed a significant reduction (p<0.001)p after 1 month, whereas no significant difference was noticed post intervention between the groups. 3D animation videos are more effective over 2D videos in periodontal disease education and knowledge recall. The application of 3D animation results also demonstrate a better visual comprehension for students and greater health care outcomes.

Head and neck cancer treatment affects quality of life. There are differences in quality of life outcomes and perceived supportive care needs between cancer patients living in metropolitan and regional-remote areas. This study investigated quality of life over the first 6 months following head and neck cancer diagnosis and observed differences in quality of life by geographical location. Prospective observational study. Tertiary hospital in Brisbane, Australia. Newly diagnosed patients who were referred for the diagnosis, and/or treatment of head and neck cancer. Quality of life was measured by the University of Washington Quality of Life Survey, version 4 (UW-QoL). Participants completed the UW-QoL questionnaire prior to starting treatment, 1 month and 6 months post treatment. Metropolitan and regional or remote status was classified according to the Australian Standard Geographic Classification-Remoteness Area system. Ninety-five participants were included at baseline; 49 and 41 participants completed the 1-month and 6-month follow-ups, respectively. Scores in most UW-QoL domains decreased between baseline and 1 month post treatment and increased towards pre-treatment scores at the 6-month follow-up (except for anxiety and saliva). Pain at baseline was significantly worse in the regional-remote participants compared with metropolitan participants. No other statistically significant differences in UW-QoL score by geographical location were observed. The findings generally did not support significant differences in quality of life outcome between metropolitan and regional-remote head and neck cancer patients. The difference in pain experience between metropolitan and regional-remote groups requires further investigation. © 2018 National Rural Health Alliance Ltd.

Recently, a new power toothbrush has been marketed with a design that fundamentally differs from other marketed power toothbrushes, in that it incorporates a round oscillating head, in conjunction with fixed bristles. The objective of this study was to compare the plaque removal efficacy of a control manual toothbrush (Colgate Navigator) to this experimental power toothbrush (Crest SpinBrush) following a single use. This study was a randomized, controlled, examiner-blind, 4-period crossover design which examined plaque removal with the two toothbrushes following a single use in 40 completed subjects. Plaque was scored before and after brushing using the Turesky Modification of the Quigley-Hein Index. Baseline plaque scores were 1.77 for both the experimental toothbrush and control toothbrush treatment groups. With respect to all surfaces examined, the experimental toothbrush delivered an adjusted (via analysis of covariance) mean difference between baseline and post-brushing plaque scores of 0.48 while the control toothbrush delivered an adjusted mean difference of 0.35. The experimental toothbrush removed, on average, 37.6% more plaque than the control toothbrush. These results were statistically significant (P< 0.001). With respect to buccal surfaces, the experimental toothbrush delivered an adjusted mean difference between baseline and post-brushing plaque scores of 0.54 while the control toothbrush delivered an adjusted mean difference of 0.42. This represents 27.8% more plaque removal with the experimental toothbrush compared to the control toothbrush. These results were also statistically significant (P= 0.001). Results on lingual surfaces also demonstrated statistically significantly (P< 0.001) greater plaque removal for the experimental toothbrush with an average of 53.4% more plaque removal.

Crossover. To compare the time required to decrease intramuscular temperature 8°C below baseline temperature, and to compare intramuscular temperature 90 minutes posttreatment, between 2 cryotherapy modalities. Cryotherapy is used to treat pain from muscle injuries. Cooler intramuscular temperatures may reduce cellular metabolism and secondary hypoxic injury to attenuate acute injury response, specifically the rate of chemical mediator activity. Modalities that decrease intramuscular temperature quickly may be beneficial in the treatment of muscle injuries. Eighteen healthy subjects received 2 cryotherapy conditions, crushed-ice bag (CIB) and cold-water immersion (CWI), in a randomly allocated order, separated by 72 hours. Each condition was applied until intramuscular temperature decreased 8°C below baseline. Intramuscular temperature was monitored in the gastrocnemius, 1 cm below subcutaneous adipose tissue. The primary outcome was time to decrease intramuscular temperature 8°C below baseline. A secondary outcome was intramuscular temperature at the end of a 90-minute rewarming period. Paired t tests were used to examine outcomes. Time to reach an 8°C reduction in intramuscular temperature was not significantly different between CIB and CWI (mean difference, 2.6 minutes; 95% confidence interval: -3.10, 8.30). Intramuscular temperature remained significantly colder 90 minutes post-CWI compared to CIB (mean difference, 2.8°C; 95% confidence interval: 2.07°C, 3.52°C). There was no difference in time required to reduce intramuscular temperature 8°C 1 cm below adipose tissue using CIB and CWI. However, intramuscular temperature remained significantly colder 90 minutes following CWI. These results provide clinicians with information that may guide treatment-modality decisions.

Abstract Background Menopausal status and use of hormonal contraception or menopausal hormone therapy (HT) may affect treatment response to selective serotonin reuptake inhibitors (SSRIs). This report evaluates whether menopausal status and use of hormonal contraceptives or menopausal HT affect outcome in women treated with citalopram. Methods In the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study, 896 premenopausal and 544 postmenopausal women were treated with citalopram for 12–14 weeks. Baseline demographic and clinical characteristics were used in adjusted analysis of the effect of menopausal status and use of hormonal contraceptives or menopausal HT on outcomes. Remission was defined as final Hamilton Rating Scale for Depression-17 (HRSD17) ≤7 or Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR16) score ≤5 and response as ≥50% decrease from the baseline QIDS-SR16 score. Results Premenopausal and postmenopausal women differed in multiple clinical and demographic baseline variables but did not differ in response or remission rates. Premenopausal women taking hormonal contraceptives had significantly greater unadjusted remission rates on the HRSD17 and the QIDS-SR16 than women not taking contraception. Response and remission rates were not different between postmenopausal women taking vs. not taking HT. Adjusted results showed no significant difference in any outcome measure across menopause status in women who were not taking contraception/HT. There were no significant differences in adjusted results across HT status in premenopausal or postmenopausal women. Conclusions In this study, citalopram treatment outcome was not affected by menopausal status. Hormonal contraceptives and HT also did not affect probability of good outcome. PMID:23398127

The aim of this study was to compare the effects of exemestane and tamoxifen on hormone levels in postmenopausal patients with hormone receptor-positive breast cancer within a Germany substudy of the Tamoxifen Exemestane Adjuvant Multinational (TEAM) trial. Within the TEAM trial, patients were randomized to receive adjuvant treatment with exemestane for 5 years or tamoxifen for 2.5-3 years followed by exemestane for 2-2.5 years. Serum levels of testosterone, dehydroepiandrosterone sulfate (DHEAS), sex hormone binding globulin (SHBG), follicle stimulating hormone (FSH) and parathyroid hormone (PTH)-intact were measured at screening and after 3, 6 and 12 months of treatment. Data on hormone levels were available from 63 patients in the tamoxifen arm and 68 patients in the exemestane arm. Treatment with exemestane resulted in decreases from baseline in SHBG and PTH-intact levels, and increases from baseline in testosterone, DHEAS and FSH levels. Tamoxifen treatment resulted in increases from baseline in SHBG and PTH-intact, whereas levels of testosterone and FSH decreased and DHEAS levels did not change. At all time points assessed, the absolute change from baseline was significantly different between tamoxifen and exemestane for testosterone, SHBG, FSH and PTH-intact (all p < 0.0001). Exemestane and tamoxifen had statistically significantly different effects on hormone levels, including testosterone, SHBG, FSH and PTH-intact.

To compare the long-term visual and anatomic outcome of treatment with photodynamic therapy (PDT) or intravitreal bevacizumab (IVB; Avastin; Genentech Inc, South San Francisco, California, USA) for choroidal neovascularization attributable to pathologic myopia (mCNV). An open-label, interventional case series. Multi-institutional. Thirty-one eyes of Japanese women who received either PDT or IVB for mCNV. Inclusion criteria were age 50 years or older, greatest linear dimension (GLD) 1200 to 3000 microm, and baseline best-corrected visual acuity (BCVA) 20/200 to 20/40. INTERVENTION PROCEDURES: Patients received either PDT or IVB (1 mg/40 microL) throughout the study, with re-treatment when necessary. BCVA and visual gain/loss at 3, 6, 12, 18, and 24 months after the initial treatment. Age, BCVA, location of CNV, refractive error, and symptom duration at baseline did not differ significantly between groups. BCVA was significantly improved at 3 to 12 months (P < .05); however, the significance was lost at 18 and 24 months in the IVB group. The PDT group showed no significant improvement within the first year, and vision slowly worsened after 12 months, becoming significantly worse at 18 and 24 months compared to baseline (P< .01). BCVA was significantly higher in the IVB group at 6 months (P< .05), and 12 months or further (P < .01). Visual gain was significantly greater in the IVB group at 6, 12, 18, and 24 months (P < .05 for 6, 18, and 24 months and P < .01 for 12 months). These findings indicate that the effects of PDT and IVB have a different time course, and that IVB provides a significantly better BCVA than PDT for mCNV over the long-term.

Individuals differ markedly in brain structure, and in how this structure degenerates during ageing. In a large sample of human participants (baseline n = 731 at age 73 years; follow-up n = 488 at age 76 years), we estimated the magnitude of mean change and variability in changes in MRI measures of brain macrostructure (grey matter, white matter, and white matter hyperintensity volumes) and microstructure (fractional anisotropy and mean diffusivity from diffusion tensor MRI). All indices showed significant average change with age, with considerable heterogeneity in those changes. We then tested eleven socioeconomic, physical, health, cognitive, allostatic (inflammatory and metabolic), and genetic variables for their value in predicting these differences in changes. Many of these variables were significantly correlated with baseline brain structure, but few could account for significant portions of the heterogeneity in subsequent brain change. Physical fitness was an exception, being correlated both with brain level and changes. The results suggest that only a subset of correlates of brain structure are also predictive of differences in brain ageing.

Anecdotal case reports, amplified by mass media and internet-based opinion groups, have recently indicated vaccinations as possibly responsible for autoimmunity/lymphoproliferation development. Multiply vaccinated Italian military personnel (group 1, operating in Italy, group 2, operating in Lebanon) were followed-up for nine months to monitor possible post-vaccine autoimmunity/lymphoproliferation onset. No serious adverse event was noticed in both groups. Multivariate analysis of intergroup differences only showed a significant association between lymphocyte increase and tetanus/diphtheria vaccine administration. A significant post-vaccine decrease in autoantibody positivity was observed. Autoantibodies were also studied by microarray analysis of self-proteins in subjects exposed to ≥4 concurrent vaccinations, without observing significant difference among baseline and one and nine months post-vaccine. Moreover, HLA-A2 subjects have been analyzed for the possible CD8T-cell response to apoptotic self-epitopes, without observing significant difference between baseline and one month post-vaccine. Multiple vaccinations in young adults are safe and not associated to autoimmunity/lymphoproliferation onset during a nine-month-long follow-up. Copyright © 2017 Elsevier Inc. All rights reserved.

In North America, the B subtype of the major group (M) of HIV-1 predominates. Phylogenetic analysis of HIV reverse transcriptase and protease sequences isolated from 479 therapy-naive patients, first seeking treatment in British Columbia between June 1997 and August 1998, revealed a prevalence of 4.4% non-B virus. A range of different subtypes was identified, including one subtype A, 11 C, two D, five CRF01_AE, and one sample that could not be reliably subtyped. Baseline CD4 courts were significantly lower in individuals harbouring the non-B subtypes (P = 0.02), but baseline viral loads were similar (P = 0.80). In this study, individuals infected with non-B variants did not have a significantly different virological response to therapy after up to 18 months.

The aim of the present study was to evaluate the effect of adjunctive chlorhexidine (CHX) mouthrinse on gingival crevicular fluid (GCF) MMP-8 and TIMP-1 levels in plaque-associated gingivitis. A total of 50 gingivitis patients were included in the present study. In addition to daily plaque control, CHX group rinsed with CHX, while placebo group rinsed with placebo mouthrinse for 4 weeks. GCF samples were collected, and clinical parameters including plaque index, papillary bleeding index, calculus index and pocket depth were recorded at baseline and 4 weeks. GCF MMP-8 and TIMP-1 levels were determined by immunofluorometric assay (IFMA) and enzyme-linked immunosorbent assay (ELISA), respectively. In both groups, GCF MMP-8 levels of anterior and posterior sites at four weeks were not different from baseline (p > 0.05). There were no significant differences in GCF MMP-8 levels between the study groups at four weeks (p > 0.05). GCF TIMP-1 levels of anterior and posterior sites at four weeks were higher compared to baseline in both groups (p < 0.05). There was no significant difference in GCF TIMP level between the study groups at four weeks (p > 0.05). CHX usage had no significant effects on the GCF MMP-8 and TIMP-1 levels in plaque-associate gingivitis. However, daily plaque control resulted in the increase of GCF TIMP-1 levels regardless of CHX usage.

Objective We conducted a randomized controlled trial to determine whether IRISS (Intervention for those Recently Informed of their Seropositive Status), a positive affect skills intervention, improved positive emotion, psychological health, physical health, and health behaviors in people newly diagnosed with HIV. Method 159 participants who had received an HIV diagnosis in the past 3 months were randomized to a 5-session, in-person, individually-delivered positive affect skills intervention or an attention-matched control condition. Results For the primary outcome of positive affect, the group difference in change from baseline over time did not reach statistical significance (p = .12; d = .30). Planned secondary analyses within assessment point showed that the intervention led to higher levels of past-day positive affect at 5, 10, and 15 months post diagnosis compared to an attention control. For antidepressant use, the between group difference in change from baseline was statistically significant (p = .006; d = −.78 baseline to 15 months) and the difference in change over time for intrusive and avoidant thoughts related to HIV was also statistically significant (p = .048; d = .29). Contrary to findings for most health behavior interventions in which effects wane over the follow up period, effect sizes in IRISS seemed to increase over time for most outcomes. Conclusions This comparatively brief positive affect skills intervention achieved modest improvements in psychological health, and may have the potential to support adjustment to a new HIV diagnosis.

To investigate the effect of atorvastatin on exercise tolerance in patients with diastolic dysfunction and exercise-induced hypertension. A randomized, double-blind, placebo-controlled prospective study was performed. Sixty patients with diastolic dysfunction (mitral flow velocity E/A <1) and exercise-induced hypertension (SBP>200 mm Hg) treated with atorvastatin (20 mg q.d) or placebo for 1 year. Cardiopulmonary exercise test and exercise blood pressure measurement were performed. Plasma B-natriuretic peptide (BNP) concentration at rest and at peak exercise, plasma high sensitive-C reaction protein (hs-CRP) and endothelin (ET) concentration were determined at baseline and after treatment. After treatment by atorvastatin, the resting SBP, pulse pressure, the peak exercise SBP and BNP were significantly decreased; and the exercise time, metabolic equivalent, maximal oxygen uptake and anaerobic threshold were increased. All of these parameters had significant differences with baseline levels (P<0.05) and the rest pulse pressure, the peak exercise SBP and BNP, and the exercise time had significant differences compared with placebo treatment (P<0.05). Plasma concentrations of hs-CRP and ET were markedly reduced by atorvastatin treatment compared with baseline and placebo (P<0.05). No difference in above parameters was found before and after placebo treatment (P>0.05). In patients with diastolic dysfunction at rest and exercise-induced hypertension, atorvastatin can effectively reduce plasma hs-CRP and ET level, lower blood pressure and peak exercise SBP, decrease peak exercise plasma BNP concentration, and ultimately improve exercise tolerance.

Plantar fasciitis (PF) is a soft tissue disorder considered to be one of the most common causes of inferior heel pain. The aim of this study was to investigate the effect of monophasic pulsed current (MPC) and MPC coupled with plantar fascia-specific stretching exercises (SE) on the treatment of PF. Forty-four participants (22 women and 22 men, with a mean age of 49 years) diagnosed with PF were randomly assigned to receive MPC (n=22) or MPC coupled with plantar fascia-specific SE (n=22). Prior to and after 4 weeks of treatment, participants underwent baseline evaluation; heel pain was evaluated using a visual analogue scale (VAS), heel tenderness threshold was quantified using a handheld pressure algometer (PA), and functional activities level was assessed using the Activities of Daily Living subscale of the Foot and Ankle Ability Measure (ADL/FAAM). Heel pain scores showed a significant reduction in both groups compared to baseline VAS scores (P<0.001). Heel tenderness improved significantly in both groups compared with baseline PA scores (P<0.001). Functional activity level improved significantly in both groups compared with baseline (ADL/FAAM) scores (P<0.001). However, no significant differences existed between the 2 treatment groups in all post-intervention outcome measures. This trial showed that MPC is useful in treating inferior heel symptoms caused by PF.

Precise relative position determination is a prerequisite for radar interferometry by formation flying satellites. It has been shown that this can be achieved by high-quality, dual-frequency GPS receivers that provide precise carrier-phase observations. The precise baseline determination between satellites flying in formation can significantly improve the accuracy of interferometric products, and has become a research interest. The key technologies of baseline determination using spaceborne dual-frequency GPS for gravity recovery and climate experiment (GRACE) formation are presented, including zero-difference (ZD) reduced dynamic orbit determination, double-difference (DD) reduced dynamic relative orbit determination, integer ambiguity resolution and relative receiver antenna phase center variation (PCV) estimation. We propose an independent baseline determination method based on a new strategy of integer ambiguity resolution and correction of relative receiver antenna PCVs, and implement the method in the NUDTTK software package. The algorithms have been tested using flight data over a period of 120 days from GRACE. With the original strategy of integer ambiguity resolution based on Melbourne-Wübbena (M-W) combinations, the average success rate is 85.6%, and the baseline precision is 1.13 mm. With the new strategy of integer ambiguity resolution based on a priori relative orbit, the average success rate and baseline precision are improved by 5.8% and 0.11 mm respectively. A relative ionosphere-free phase pattern estimation result is given in this study, and with correction of relative receiver antenna PCVs, the baseline precision is further significantly improved by 0.34 mm. For ZD reduced dynamic orbit determination, the orbit precision for each GRACE satellite A or B in three dimensions (3D) is about 2.5 cm compared to Jet Propulsion Laboratory (JPL) post science orbits. For DD reduced dynamic relative orbit determination, the final baseline precision for two GRACE satellites formation is 0.68 mm validated by K-Band Ranging (KBR) observations, and average ambiguity success rate of about 91.4% could be achieved.

Mental health-related stigma is a major public health issue, and is an obstacle to the possibility for successful treatment, recovery, and reintegration. To examine attitudes towards mental illness among employees in the social services. The study design was part of a large randomized trial, and data presented in this study are baseline data from this trial. Respondents completed a baseline questionnaire to assess the respondents' attitudes. A significant difference was found between employees' personal attitudes towards depression and schizophrenia. The same significant difference was found in the employees' perceived attitudes. Furthermore, a significant difference was found between the employees' personal and perceived attitudes. A significant difference was found between the respondents wish for social distance towards depression and schizophrenia in all cases, except regarding the willingness to provide a job at one's own workplace. Employees in the social services are comparable to the general public concerning attitudes towards mental illness. The results indicate that the employees in social services could have great use of gaining more knowledge about mental illness and ways in which to recognize a mental illness, in order to be able to offer the right kind of help and reduce the treatment gap concerning people suffering from mental illness.

Background This study describes differences in trajectories of self-reported mental health in an ageing cohort, according to their housing, while controlling for confounders. Methods The General Health Questionnaire was measured on six occasions as part of Whitehall II cohort study of office-based British civil servants (1985-2009); 10,308 men and women aged 35-55 at baseline. Results Home-ownership was the predominant tenure at baseline and increased over the life-course, but the social gradient remained. In the bivariate analysis, by phase nine, renters had higher (poorer mental health) GHQ scores (55.48) than owner occupiers (51.98). Those who reported difficulty paying bills or problems with housing had higher GHQ scores at baseline (financial difficulties 57.70 vs 54.34; house problems 58.06 vs 53.99) and this relative difference increased by phase nine (financial difficulties 59.64 vs 51.67; house problems 56.68 vs 51.22). In multivariate models, the relative differences in GHQ scores by tenure increased with age, but were no longer significant after adjusting for confounders. Whereas GHQ scores for those with housing problems and financial difficulties were still significantly higher as participants grew older. Conclusion The social gradient in the effect of home ownership on mental health, which is evident at baseline, diminishes as people get older, whereas housing quality and financial problems become relatively more important in explaining older people's health. Inequalities in housing quality and ability to deal with household financial problems will become increasingly important mental health issues as the population ages. PMID:21884619

Hemodialysis patients experience an elevated risk of malnutrition associated with increased morbidity and mortality. Nocturnal hemodialysis (NHD) results in more effective removal of waste products and fluids. Therefore, diet and fluid restrictions are less restricted in NHD patients. However, it is ambiguous whether transition from conventional hemodialysis (CHD) to NHD leads to improved intake and nutritional status. We studied the effect of NHD on protein intake, laboratory indices of nutritional status, and body composition. Systematic review with meta-analysis. NHD patients. Systematic literature search from databases, Medline, Cinahl, EMBASE and The Cochrane Library, to identify studies reporting on nutritional status post-transition from CHD to NHD. Transition from CHD to NHD. Albumin, normalized protein catabolic rate (nPCR), dry body weight (DBW), body mass index (BMI), phase angle, protein intake, and energy intake. Systematic literature search revealed 13 studies comprising 282 patients that made the transition from CHD to NHD. Meta-analysis included nine studies in 229 patients. In control group controlled studies (n = 4), serum albumin increased significantly from baseline to 4-6 months in NHD patients compared with patients that remained on CHD (mean difference 1.3 g/l, 95% CI 0.02; 2.58, p = 0.05). In baseline controlled studies, from baseline to 4-6 months of NHD treatment, significant increases were ascertained in serum albumin (mean difference (MD) 1.63 g/l, 95% CI 0.73-2.53, p<0.001); nPCR (MD 0.16 g/kg/day; 95% CI 0.04-0.29, p = 0.01); protein intake (MD 18.9 g, 95% CI 9.7-28.2, p<0.001); and energy intake (MD 183.2 kcal, 95% CI 16.8-349.7, p = 0.03). Homogeneity was rejected only for nPCR (baseline versus 4-6 months). DBW, BMI, and phase angle did not significantly change. Similar results were obtained for comparison between baseline and 8-12 months of NHD treatment. Most studies had moderate sample sizes; some had incomplete dietary records and relatively brief follow-up period. Studies markedly differed with regard to study design. NHD is associated with significantly higher protein and energy intake as well as increases in serum albumin and nPCR. However, the data on body composition are inconclusive.

To analyze the quality of life (QOL) and performance status (PS) (secondary outcome) in patients with stage III to IV head and neck cancer (HNC) enrolled on a prospective randomized phase 3 trial comparing radiation-cisplatin without cetuximab (CIS) or with cetuximab (CET/CIS). The QOL hypothesis proposed a between-arm difference in Functional Assessment of Cancer Therapy-Head and Neck (FACT-HN) total score of ≥10% of the instrument range from baseline to 1 year. Patients who gave consent to the QOL/PS study completed the FACT-HN, Performance Status Scale for HNC (PSS-HN), and EuroQol (EQ-5D) at baseline through to 5 years. The pretreatment QOL/PS scores were correlated with outcome and p16 status in patients with oropharyngeal cancer (OPC). Of 818 analyzable patients, the 1-year change from baseline score for FACT-HN total was -0.41 (CIS arm) and -5.11 (CET/CIS arm) (P=.016), representing a 3.2% between-arm change of the FACT-HN total score. The mean EQ-5D index and PSS-HN scores were not significantly different between arms. The p16-positive OPC patients had significantly higher baseline and 1-year scores for PSS-HN, FACT-HN total, physical and functional subscales, and 2-years for the EQ-5D index compared with p16-negative OPC patients. Higher pretreatment PSS-HN diet, PSS-HN eating, FACT-HN, and EQ-5D index scores were associated with better overall survival (OS) and progression-free (PFS) survival on multivariate analysis. Higher baseline FACT-HN total, functional, physical subscale, and EQ-5D index scores were associated with improved OS and PFS in p16-positive OPC patients but not in p16-negative and non-OPC patients. There was no clinically meaningful difference in QOL/PS between arms. The p16-positive OPC patients had significantly higher QOL/PS than did p16-negative patients. Pretreatment QOL/PS is a significant independent predictor of outcome in locally advanced HNC. Copyright © 2016 Elsevier Inc. All rights reserved.

Pulsar positions can be measured with high precision using both pulsar timing methods and very long baseline interferometry (VLBI). Pulsar timing positions are referenced to a solar-system ephemeris, whereas VLBI positions are referenced to distant quasars. Here, we compare pulsar positions from published VLBI measurements with those obtained from pulsar timing data from the Nanshan and Parkes radio telescopes in order to relate the two reference frames. We find that the timing positions differ significantly from the VLBI positions (and also differ between different ephemerides). A statistically significant change in the obliquity of the ecliptic of 2.16 ± 0.33 mas is found for the JPL ephemeris DE405, but no significant rotation is found in subsequent JPL ephemerides. The accuracy with which we can relate the two frames is limited by the current uncertainties in the VLBI reference source positions and in matching the pulsars to their reference source. Not only do the timing positions depend on the ephemeris used in computing them, but also different segments of the timing data lead to varying position estimates. These variations are mostly common to all ephemerides, but slight changes are seen at the 10 μas level between ephemerides.

(i) To test whether theory-guided interventions are more effective than conventional dental instruction (CDI) for changing oral hygiene in adolescents and (ii) to examine whether such interventions equally benefit both genders and different socio-economic (SES) groups. A total of 244 adolescents were recruited from three schools, and cluster randomization allocated adolescents to one of the three types of interventions: two were theory-based interventions (Precaution Adoption Process Model or Authoritative Parenting Model) and CDI served as an active control. Oral hygiene levels % (OH) were assessed at baseline, after 3 months and after 12 months. A complete data set was available for 166 adolescents (the total follow-up rate: 69%). There were no significant differences in baseline OH between those who participated throughout the study and those who dropped out. Bivariate and multivariate analyses showed that theory-guided interventions produced significant improvements in oral hygiene and that there were no significant gender or socio-economic differences. Theory-guided interventions produced more positive changes in OH than CDI, and these changes did not differ between gender and SES groups. © 2017 John Wiley & Sons A/S.

Performance analysis of an integrated GPS/inertial attitude determination system. M.S. Thesis - MIT

The performance of an integrated GPS/inertial attitude determination system is investigated using a linear covariance analysis. The principles of GPS interferometry are reviewed, and the major error sources of both interferometers and gyroscopes are discussed and modeled. A new figure of merit, attitude dilution of precision (ADOP), is defined for two possible GPS attitude determination methods, namely single difference and double difference interferometry. Based on this figure of merit, a satellite selection scheme is proposed. The performance of the integrated GPS/inertial attitude determination system is determined using a linear covariance analysis. Based on this analysis, it is concluded that the baseline errors (i.e., knowledge of the GPS interferometer baseline relative to the vehicle coordinate system) are the limiting factor in system performance. By reducing baseline errors, it should be possible to use lower quality gyroscopes without significantly reducing performance. For the cases considered, single difference interferometry is only marginally better than double difference interferometry. Finally, the performance of the system is found to be relatively insensitive to the satellite selection technique.

Dietary modification, through supplementation and elimination diets, has become an area of interest to help slow skin aging, reduce symptom severity or prevent reoccurrence of certain dermatologic conditions [Clinical Dermatology vol. 31 (2013) 677-700]. Free radical components (reactive oxygen species or ROS) or lipid peroxide (LPO) is involved in the pathogenesis and progression of accelerated skin aging when prolonged oxidative stress occurs. The use of antioxidant-related therapies such as nutraceuticals is of particular interest in restoring skin homeostasis. Antioxidant carotenoid zeaxanthin is concentrated in the eye and skin tissue and believed to decrease the formation of ROS associated with UV light exposure. With zeaxanthin, phytoceramides, and botanical extracts an oral and topical test product (with zeaxanthin, algae extracts, peptides, hyaluronate) have been developed to improve the appearance and condition of skin when used as directed. Subjects were divided into three groups: two tests (skin formula 1 - oral product alone (ZO-1), skin formula 2- oral product with topical product (ZO-2 + ZT)), and one placebo control. The study consisted of a washout visit, baseline (randomization), week two (2), week four (4), week six (6), week eight (8), and week twelve (12). Key parameters measured were as follows: fine lines, deep lines, total wrinkles, wrinkle severity, radiance/skin color (L, a*, b*), discolorations, and skin pigment homogeneity. Thirty-one subjects completed the twelve-week study; no adverse events were recorded during the study. Statistically significant improvements from baseline mean hydration score were observed in active groups at weeks 2, 6, and 8. A statistically significant difference was observed between mean differences from baseline scores for total wrinkle count at week 4 for the combination active groups compared to placebo. A statistically significant difference from baseline scores for fine lines count was also observed at the week 4 visit compared to placebo for both active groups. Statistically significant differences from baseline scores for average wrinkles severity were seen for week 12 visit for both active groups compared to placebo. We have shown that the combination of zeaxanthin-based dietary supplement plus a topical formulation produces superior hydration to that of placebo. Additionally, we have shown that the combination of oral and topical combination vs. oral alone has superior abilities to improve parameters associated with facial lines and wrinkles compared to placebo, although the dietary supplement alone proved most effective in reducing wrinkle count and severity. © 2016 Wiley Periodicals, Inc.

Objective To evaluate the effectiveness and safety of polyunsaturated fatty acids for the treatment of the premenstrual syndrome (PMS) using a graded symptom scale and to assess the effect of this treatment on basal plasma levels of prolactin and total cholesterol. Methods A randomized, double-blind, placebo-controlled study was conducted with 120 women with PMS divided into three groups and treated with 1 or 2 grams of the medication or placebo. Symptoms were recorded over a 6-month period using the Prospective Record of the Impact and Severity of Menstruation (PRISM) calendar. Total cholesterol and prolactin levels were measured. Analysis of variance (ANOVA), Pearson's chi-square test, Wilcoxon's nonparametric signed-rank test for paired samples and the Mann-Whitney nonparametric test for independent samples were used in the statistical analysis. Results There were no differences in age, marital status, schooling or ethnicity between the groups. In the group treated with 1 gram of the medication, a significant reduction was found when the median PRISM score recorded in the luteal phase at baseline (99) was compared with the median score recorded in the 3rd month (58) and in the 6th month of evaluation (35). In the 2-gram group, these differences were even more significant (baseline score: 98; 3rd month: 48; 6th month: 28). In the placebo group, there was a significant reduction at the 3rd but not at the 6th month (baseline: 96.5; 3rd month: 63.5; 6th month: 62). The difference between the phases of the menstrual cycle was greater in the 2-gram group compared to the group treated with 1 gram of the medication. There were no statistically significant differences in prolactin or total cholesterol levels between baseline values and those recorded after six months of treatment. Conclusion The difference between the groups using the medication and the placebo group with respect to the improvement in symptomatology appears to indicate the effectiveness of the drug. Improvement in symptoms was higher when the 2-gram dose was used. This medication was not associated with any changes in prolactin or total cholesterol levels in these women. PMID:21241460

With the advent of the National Collegiate Athletic Association's (NCAA's) mandating the presence and practice of concussion-management plans in collegiate athletic programs, institutions will consider potential approaches for concussion management, including both baseline and normative comparison approaches. To examine sport and team differences in baseline performance on a computer-based neurocognitive measure and 2 standard sideline measures of cognition and balance and to determine the potential effect of premorbid factors sex and height on baseline performance. Cross-sectional study. University laboratory. A total of 437 NCAA Division II student-athletes (males = 273, females = 164; age = 19.61 ± 1.64 years, height = 69.89 ± 4.04 inches [177.52 ± 10.26 cm]) were recruited during mandatory preseason testing conducted in a concussion-management program. The computerized Concussion Resolution Index (CRI), the Standardized Assessment of Concussion (Form A; SAC), and the Balance Error Scoring System (BESS). Players on the men's basketball team tended to perform worse on the baseline measures, whereas soccer players tended to perform better. We found a difference in total BESS scores between these sports (P = .002). We saw a difference between sports on the hard-surface portion of the BESS (F6,347 = 3.33, P = .003, ηp(2) = 0.05). No sport, team, or sex differences were found with SAC scores (P > .05). We noted differences between sports and teams in the CRI indices, with basketball, particularly the men's team, performing worse than soccer (P < .001) and softball/baseball (P = .03). When sex and height were considered as possible sources of variation in BESS and CRI team or sport differences, height was a covariate for the team (F1,385 = 5.109, P = .02, ηp(2) = 0.013) and sport (F1,326 = 11.212, P = .001, ηp(2) = 0.033) analyses, but the interaction of sex and sport on CRI indices was not significant in any test (P > .05). Given that differences in neurocognitive functioning and performance among sports and teams exist, the comparison of posttraumatic and baseline assessment may lead to more accurate diagnoses of concussion and safer return-to-participation decision making than the use of normative comparisons.

The green tea extract is a naturally occurring product having beneficial effects that counteract with the pathobiological features of periodontitis and diabetes mellitus. Hence, the present study was aimed at incorporation of green tea extract into hydroxylpropyl methylcellulose and investigates its efficacy in chronic periodontitis patients associated with and without diabetes mellitus. For the in vitro study, formulation of green tea strips and placebo strips, and analysis of drug release pattern from the green tea strips at different time intervals were performed. For the in vivo study, 50 patients (20-65 years), including 25 systemically healthy patients with chronic periodontitis (group 1) and 25 diabetic patients with chronic periodontitis (group 2) were enrolled. In each patient, test and control sites were identified for the placement of green tea and placebo strips, respectively. Gingival Index (GI), Probing Pocket Depth (PPD), and Clinical Attachment Level (CAL) were examined at baseline, first, second, third, and fourth weeks. Microbiological analysis for Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans was performed at baseline and fourth week. The in vitro study showed 10.67% green tea release at 30 min; thereafter, a slow release was noted till 120 min. Both groups showed significant reduction in GI scores at the test sites. Group 1 showed significant (P < 0.001) PPD reduction at different time intervals at the test sites. However, group 2 showed significant reduction from baseline (5.30 ± 0.70) to fourth week (3.5 ± 0.97). Statistically significant gain in CAL at the test sites was observed both in group 1 (1.33 mm) and group 2 (1.43 mm). The prevalence of P. gingivalis in group 1 test sites was significantly reduced from baseline (75%) to fourth week (25%). Local drug delivery using green tea extract could be used as an adjunct in the treatment of chronic periodontitis in diabetic and non-diabetic individuals.

Seasonal modulation of baseline glucocorticoid concentrations as well as the sensitivity of the hypothalamic-pituitary-adrenal (HPA) axis plays an important role in supporting critical life-history events such as seasonal reproduction and migration. Despite numerous studies on adrenocortical modulation, little is known about the exact timing of this seasonal modulation with respect to critical life-history stages. We tested the hypothesis that seasonal modulation of the HPA axis during the spring mating season in male red-sided garter snakes (Thamnophis sirtalis parietalis) is temporally linked to the mechanisms regulating dispersal. We compared hormonal responses to capture stress in courting male red-sided garter snakes collected from the den site and den perimeter to those of dispersing snakes collected 0.6 km from the den. We also investigated possible changes in steroid hormones during the spring mating season. These studies support previous findings that plasma androgen and corticosterone concentrations significantly decline over the mating season. Our results demonstrate that males 0.6 km into a 15-20 km route to the feeding grounds have lower baseline corticosterone concentrations than male snakes actively courting at the den. Dispersing males also exhibit a typical stress response marked by a significant increase in corticosterone while actively courting males do not. Capture stress did not significantly influence androgen concentrations of either courting or dispersing male red-sided garter snakes. There were no significant differences in body composition indices among male snakes collected from the den, den perimeter, or 0.6 km away from the den. However, we did observe a significant negative correlation between baseline corticosterone levels and body composition indices. These data suggest that breeding is a distinct stage accompanied by specific physiological parameters that differ from those during dispersal to the feeding grounds. Our results indicate that declining baseline corticosterone concentrations may play a role in the behavioral switch between actively courting and dispersing (i.e., feeding) in the late spring.

To determine the effects of low-dose pioglitazone on plasma adipocyte-derived cytokines, high-sensitivity C-reactive protein (hs-CRP), and components of the metabolic syndrome in adults with the metabolic syndrome without diabetes mellitus. Prospective, randomized, double-blind, placebo-controlled study. University of Colorado Clinical and Translational Research Center. Thirty-two men and women, aged 30-60 years, without diabetes who had a clinical diagnosis of the metabolic syndrome, as defined by the American Heart Association/National Heart, Lung, and Blood Institute criteria. Patients were randomly assigned to receive oral pioglitazone 7.5 mg daily or matching placebo for 8 weeks. The primary end point was the change in plasma high-molecular-weight (HMW) adiponectin level from baseline to week 8. Other end points were changes in plasma total adiponectin, omentin, and hs-CRP levels, and changes in components of the metabolic syndrome (e.g., insulin sensitivity) from baseline to week 8. Pioglitazone was associated with a significant increase in plasma HMW adiponectin from baseline to week 8 compared with placebo (+47% vs -10%, p<0.001). Insulin sensitivity increased significantly from baseline to week 8 in the pioglitazone group (+88%, p=0.02) but not in the placebo group (+15%, p=0.14). Change in HMW adiponectin was significantly correlated with the change in insulin sensitivity in the pioglitazone group (r = 0.784, p=0.003). No significant differences in mean percentage changes in plasma total adiponectin, omentin, and hs-CRP levels were observed between the pioglitazone and placebo groups. Likewise, changes in body weight, insulin sensitivity, glucose, lipids, and blood pressure did not differ significantly between the groups. Low-dose pioglitazone favorably modulates plasma HMW adiponectin, which was associated with an improvement in insulin sensitivity, in patients with the metabolic syndrome without diabetes. © 2016 Pharmacotherapy Publications, Inc.

Because epidemiological studies provide evidence that periodontal infections are associated with an increased risk of progression of cardiovascular and cerebrovascular disease, we postulated that endothelial dysfunction, a critical element in the pathogenesis of atherosclerosis, would be present in patients with periodontal disease. We tested endothelial function in 30 patients with severe periodontitis and 31 control subjects using flow-mediated dilation (FMD) of the brachial artery. The groups were matched for age, sex, and cardiovascular risk factors. Three months after periodontal treatment, including both mechanical and pharmacological therapy, endothelial function was reassessed by brachial artery FMD. Markers of systemic inflammation were measured at baseline and at follow up. Flow-mediated dilation was significantly lower in patients with periodontitis than in control subjects (6.1% +/- 4.4% vs 8.5% +/- 3.4%, P = .002). Successful periodontal treatment resulted in a significant improvement in FMD (9.8% +/- 5.7%; P = .003 compared to baseline) accompanied by a significant decrease in C-reactive protein concentrations (1.1 +/- 1.9 vs 0.8 +/- 0.8 at baseline, P = .026). Endothelium-independent nitro-induced vasodilation did not differ between the study groups at baseline or after periodontal therapy. These results indicate that treatment of severe periodontitis reverses endothelial dysfunction. Whether improved endothelial function will translate into a beneficial effect on atherogenesis and cardiovascular events needs further investigation.

Sexual dysfunction is a complaint of 30-50% of American women. Aside from hormone replacement therapy, there are no current FDA-approved medical treatments for female sexual complaints. The goal of this pilot study was to determine safety and efficacy of sildenafil for use in women with sexual arousal disorder (SAD). Evaluations were completed on 48 women with complaints of SAD. Physiologic measurements, including genital blood flow, vaginal lubrication, intravaginal pressure-volume changes, and genital sensation were recorded pre- and postsexual stimulation at baseline and following 100 mg sildenafil. Subjective sexual function was assessed using a validated sexual function inventory at baseline and following 6 weeks of home use of sildenafil. At termination of the study patients also completed an intervention efficacy index (FIEI). Following sildenafil, poststimulation physiologic measurements improved significantly compared to baseline. Baseline subjective sexual function complaints, including low arousal, low desire, low sexual satisfaction, difficulty achieving orgasm, decreased vaginal lubrication, and dyspareunia also improved significantly following 6 weeks home use of sildenafil. Sildenafil appears to significantly improve both subjective and physiologic parameters of the female sexual response. Double-blind, placebo-controlled studies are currently in progress to further determine efficacy of this medication for treatment of female sexual dysfunction complaints in different populations of women.

High circulating tumor cell (CTC) counts are associated with poor prognosis in advanced prostate cancer, and recently CTC number was suggested to be a surrogate for survival in metastatic castrate-resistant prostate cancer (mCRPC). Ki67 and vimentin are well-characterised markers of tumour cell proliferation and the epithelial-mesenchymal transition (EMT), respectively. Here we asked if the expression of vimentin and Ki67 in CTCs offered prognostic or predictive information in mCRPC. In two separate patient cohorts, anti-vimentin or anti-Ki67 antibodies were added to the free channel in the CellSearch® system for analysis of peripheral blood samples. For each cohort, association of CTC number with clinical characteristics were assessed using Fisher's exact, Mann-Whitney and chi-squared tests. Kaplan-Meier method and log-rank tests were used to analyse overall survival (OS) of vimentin-expressing and Ki67-expressing CTC patient cohorts. In this retrospective analysis, CTC vimentin expression was analysed in 142 blood samples from 93 patients, and CTC Ki67 expression was analysed in 90 blood samples from 51 patients. In the vimentin cohort, 80/93 (86 %) of baseline samples from patients were CTC-positive overall (≥1 total CTC per 7.5 mls blood), and 30/93 (32.3 %) vimentin CTC-positive (≥1 vimentin-positive CTC per 7.5 mls blood). 41/51 (80.4 %) of baseline samples from patients in the Ki67 cohort were CTC-positive overall, and 23/51 (45.1 %) Ki67 CTC-positive (≥1 Ki67-positive CTC per 7.5 mls blood). There was no significant difference in baseline PSA in patients with vimentin-positive CTC at baseline versus those with no vimentin-positive CTC at baseline (p = 0.33). A significant reduction in OS was shown in patients with vimentin-positive CTC compared to those without vimentin-positive CTC (median 305 days vs 453 days, p = 0.0293). There was no significant difference in baseline PSA in patients with Ki67-positive CTC at baseline versus those without Ki67-positive CTC (p = 0.228), but OS was significantly reduced in the Ki67-positive CTC group (median 512 days vs 751 days, p = 0.0091). No changes in relative proportion of vimentin- or Ki67-positive CTCs were observed in post-treatment samples compared to baseline. Analysis of vimentin and Ki67 expression can straightforwardly be assessed in CTCs from patients with mCRPC. Poorer survival outcomes were observed in vimentin- and Ki67-positive CTC patients.

The study investigated the relationship between cognitive factors and gains in number recall following training in a number-consonant mnemonic in a sample of 112 older adults (M = 70.9 years). The cognitive factors examined included baseline episodic memory, working memory, processing speed, and verbal knowledge. In addition, predictors of maintenance of gains to a follow-up assessment, eight months later, were examined. Whereas working memory was a prominent predictor of baseline recall, the magnitude of gains in recall from pre- to post-test assessments were predicted by baseline episodic memory, processing speed, and verbal knowledge. Verbal knowledge was the only significant predictor of maintenance. Collectively, the results indicate the need to consider multiple factors to account for individual differences in memory plasticity. The potential contribution of additional factors to individual differences in memory plasticity is discussed.

The objective of this study was to determine the efficacy of individually designed herbal formulas according to the rules of Traditional Chinese Medicine (TCM) in patients with osteoarthritis of the hip and knee. This was a randomized, controlled, double-blind study with two parallel groups. This study was conducted at the University-centre in Gars am Kamp/Austria and was organized by the Institute of TCM and Complementary Medicine of the Danube University Krems /Austria. The study comprised female and male patients with osteoarthritis of hip or knee aged between 45 and 75 years. Patients were randomized into a treatment with individualized, water-based herbal decoctions prepared in a standardized cooking process (Verum group) or to a treatment with nonspecific presumably ineffective, water-based herbal decoctions (Control group). The primary outcome was the comparison of change between the intervention groups in the Western Ontario and McMaster Universities lower limb global index questionnaire (WOMAC global index) between baseline and week 20. Secondary outcomes included subscales of WOMAC for pain (A), stiffness (B), and functional impairment (C) and general quality of life in the form of the SF-36 questionnaire. Altogether, 102 patients were randomized in this trial. The demographic and medical baseline characteristics were comparable in the 2 groups. The change of the WOMAC global index and all three subscales was significant in both groups between week 20 and baseline (verum group, global WOMAC: at baseline 47 [SD ± 11.8] and at week 20: 24 (SD ± 18.3); change of mean 23; p > 0.001; control group; global WOMAC: at baseline: 48 (SD ± 14.7) and at week 20: 25 (SD ± 18.3); change of mean 23; p > 0.001). However, there was no significant difference (p = 0.783) between the treatment groups. There were significant changes in the subscales "physical functioning," "bodily pain," "vitality," "social-functioning," and "role-physical" of the SF-36 in both study groups between 20 weeks and baseline, but again no significant difference between the groups. There were no drug-related serious adverse events. While the individual prescription consisting of medicinal herbs according to TCM diagnosis investigated in this trial tend to improve the osteoarthritis, the same effect was also achieved with the nonspecific prescription.

Fetal electrocardiography (FECG) places electrodes on the maternal abdomen to convert the fetal electrocardiosignals into fetal heart rate (FHR), improving the accuracy and comfort of pregnant woman. At the same time, FECG simplifies the procedure of long term monitoring in the perinatal period. Investigating the influence of gestational age and time of day on FHR features to distinguish between non-stress test (NST) normal fetuses and NST suspicious fetuses. A novel method of FHR baseline estimation was presented; then baseline value and fetal heart rate variation (FHRV) were analyzed in the time domain using FHR signals recorded from 52 fetuses. Baseline values in 1:00, 2:00, 4:00, 5:00 and heart rate variation (HRV) distribution showed a significant difference (p< 0.05) between NST normal fetuses and NST suspicious fetuses. The results suggest that NST normal and suspicious fetuses had same outcome and different FHR features. Accurately distinguishing normal fetuses and suspicious fetuses is important for lowering the false positive rate and reducing unnecessary clinical intervention.

AIM This study evaluated the efficacy of a child-focused versus context-focused intervention in improving performance of functional tasks and mobility in young children with cerebral palsy. METHOD A randomized controlled trial cluster research design enrolled 128 children (49 females, 79 males; age range 12mo to 5y 11mo; mean age 3y 6mo, SD −1y 5mo) who were diagnosed with cerebral palsy. Children across levels I to V on the Gross Motor Classification System (GMFCS) were included in the study. Children were excluded if there were planned surgical or medication changes during the intervention period. Therapists from 19 children's rehabilitation centers were block randomized (by occupational therapist or physical therapist) to a treatment arm. Children from consenting families followed their therapists into their assigned group. Children received child-focused (n=71) or context-focused intervention (n=57) over 6 months, returning to their regular therapy schedule and approach between 6 and 9 months. The primary outcome measure was the Pediatric Evaluation of Disability Inventory (PEDI). Secondary outcome measures included the Gross Motor Function Measure (GMFM-66), range of motion of hip abduction, popliteal angle and ankle dorsiflexion, the Assessment of Preschool Children's Participation (APCP), and the Family Empowerment Scale (FES). Outcome evaluators were masked to group assignment and completed assessments at baseline, 6 months, and 9 months. RESULTS Ten children did not complete the full intervention, six in the child group and four in context group. GMFCS levels for children in the study were level I (n=37), level II (n=23), level III (n=21), level IV (n=21), and level V (n=26). There were no significant differences at baseline between the treatment groups for GMFCS level, parental education, or parental income. For the PEDI, there was no significant difference between the treatment groups, except for a small effect (p<0.03) on the Caregiver Assistance Mobility subscale between baseline and 9 months. The mean scores of both groups changed significantly on the Functional Skills Scales (p<0.001) and Caregiver Assistance Scales (p<0.02) of the PEDI after the 6-month intervention. There was no additional statistically significant change on the PEDI during the follow-up period from 6 to 9 months. A subgroup effect was found for age (p<0.001), with children younger than 3 years changing significantly more than older children. GMFCS level at baseline did not influence the amount of change on the PEDI scales. There were no significant differences between the treatment groups on the GMFM, range of motion measures, APCP or FES assessments. For the GMFM, there was a significant change over time from baseline to 6 months (p<0.001) and no significant change between 6 and 9 months. There was no adverse side effect as range of motion did not decrease in either group. Hip abduction increased significantly (p<0.01) at the 9-month assessment for both groups. For the APCP, significant changes for both treatment groups were found between baseline and 6 months for play intensity (p<0.04), physical activity intensity and diversity (p<0.001), and total score intensity (p<0.01). INTERPRETATION This study shows that child- or context-focused therapy approaches are equally effective and that frequency of intervention may be a critical component of successful intervention. Further evaluation is required to identify the various `dose-response' relations of amount of treatment and changes in functional abilities. PMID:21569012

Repaglinide and glimepiride are relatively new oral hypoglycemic agents. Few data are available concerning their effects on metabolic parameters other than measures of glycemic control. In addition to assessing the effects of repaglinide and glimepiride on glycemic control in patients with type 2 diabetes mellitus, this study also examined the effects of these agents on 3 metabolic parameters known to be cardiovascular risk factors--lipoprotein(a) (Lp[a]), plasminogen activator inhibitor-1 (PAI-1), and homocysteine (Hcy). This randomized, placebo-controlled, double-blind trial was conducted at a single center in Italy. Eligible patients were nonsmokers; had no hypertension or coronary heart disease; were taking no hypolipidemic drugs, diuretics, beta-blockers, or thyroxin; and had normal renal function. After an initial 4-week placebo washout period, patients were randomized to receive repaglinide 1 mg/d or glimepiride 1 mg/d. The dose of study drug was optimized over an 8-week titration period, which was followed by a 12-month treatment period. Measures of glycemic control (glycated hemoglobin [HbA1c], fasting plasma glucose [FPG], postprandial plasma glucose [PPG], fasting plasma insulin [FPI], postprandial plasma insulin [PPI]) and the other metabolic parameters of interest were assessed after 6 and 12 months of treatment. One hundred twenty-four patients (63 women, 61 men) completed the study, 62 in each treatment group. There were no significant differences in demographic characteristics between groups. After 6 and 12 months of treatment, FPG levels and HbA1c values were significantly reduced from baseline in both groups (6 months, P < 0.05; 12 months, P < 0.01). After 6 months, PPG levels were significantly decreased only in the repaglinide group (P < 0.05 vs baseline); at 12 months, however, PPG levels were significantly reduced from baseline in both groups (P < 0.01 repaglinide, P < 0.05 glimepiride). No significant changes from baseline in FPI or PPI levels were seen in either group at 6 months, although FPI levels were significantly increased in the repaglinide group at 12 months (P < 0.05). Repaglinide significantly lowered levels of Lp(a), PAI-1, and Hcy after 12 months (all, P < 0.05 vs baseline). Glimepiride significantly lowered levels of Lp(a) and Hcy after 6 months (both, P < 0.05 vs baseline) and levels of Lp(a) (P < 0.01 vs baseline), Hcy (P < 0.01 vs baseline), and PAI-1 (P < 0.05 vs baseline) after 12 months. Repaglinide and glimepiride improved glycemic control and reduced levels of other metabolic parameters of interest in this population of patients with type 2 diabetes. It is possible that the reductions in Lp(a), PAI-1, and Hcy were the result of improved glucose metabolism; however, the possibility that repaglinide and glimepiride may have a direct effect on these parameters should not be excluded.
Emotional intelligence, trauma severity, and emotional expression.

This study investigated Emotional Intelligence (EI) as a moderator for the association between emotional expression and adaptive trauma processing, as measured by depressive symptoms. Using Pennebaker's written emotional expression paradigm, 105 participants were assigned to either a conventional trauma-writing or religious trauma-writing condition. Depressive symptoms were assessed at baseline and again at one-month post writing. No significant association between EI and religiousness was found at baseline. Results indicated a three-way interaction among EI, trauma severity, and writing condition on depressive symptoms at follow-up. For the religious trauma-writing condition only, there was a significant difference between high- versus low-EI participants who experienced more severe trauma in depressive symptoms at follow-up, such that low-EI participants registered less depressive symptoms than high-EI participants; while there was no significant difference between low versus high EI for participants with less severe trauma. These findings encourage further investigation of the conditions under which religion may be a beneficial factor in trauma adaptation.

The effect of an interval exercise training (ITE) program on heart rate variability (HRV) was studied in 8 patients with Charcot-Marie-Tooth (CMT) disease and 8 healthy controls. At baseline, all subjects underwent ambulatory 24-hour Holter electrocardiographic (ECG) monitoring to evaluate HRV. HRV analysis was repeated on CMT patients after they completed a 24-week ITE program on a cycle ergometer. Before exercise, all HRV indices were lower in patients compared with controls, and the difference reached statistical significance for pNN50 (percent of differences between adjacent R-R intervals exceeding 50 ms). After ITE, time- and frequency-domain indices were significantly improved, particularly at night (+8% mean R-R interval, +95% pNN50, 52% reduction in low/high-frequency ratio). We observed significant increases in some of the time and frequency parameters, and values sometimes exceeded those of controls at baseline. Our results suggest that ITE improves HRV modulation in CMT patients by enhancing parasympathetic activity. Copyright © 2011 Wiley Periodicals, Inc.

Purpose. To examine the efficacy of ophthalmic rebamipide suspensions on ocular surface disorders induced by antiglaucoma eye drops. Patients and Methods. Forty eyes of 40 patients receiving latanoprost (0.005%) and timolol (0.5%) were included in this randomized prospective study. The patients were randomly divided into two groups (n = 20): the rebamipide-treated group and control group. Changes in intraocular pressure, tear film break-up time (TBUT), and corneal epithelial barrier function were evaluated at baseline, 4 weeks, and 8 weeks after rebamipide administration. Furthermore, superficial punctate keratopathy severity was evaluated by scoring the lesion area and density. Results. There was no significant difference in intraocular pressure before and after rebamipide treatment. However, corneal epithelial barrier function improved significantly 4 and 8 weeks after rebamipide treatment. TBUT was partially, but significantly, increased (P = 0.02) 8 weeks after rebamipide treatment, whereas no significant change was observed at 4 weeks. Additionally, a significant decrease in area and density of keratopathy was observed 8 weeks after rebamipide treatment but not at 4 weeks. The control group showed no significant difference compared to baseline. Conclusions. Our data suggests that rebamipide treatment may reduce the occurrence of drug-induced ocular surface disorder.

We predict the present-day rates of change of the lengths of 19 North American baselines due to the glacial isostatic adjustment process. Contrary to previously published research, we find that the three dimensional motion of each of the sites defining a baseline, rather than only the radial motions of these sites, needs to be considered to obtain an accurate estimate of the rate of change of the baseline length. Predictions are generated using a suite of Earth models and late Pleistocene ice histories, these include specific combinations of the two which have been proposed in the literature as satisfying a variety of rebound related geophysical observations from the North American region. A number of these published models are shown to predict rates which differ significantly from the VLBI observations.

Women have lower serum creatinine values than men for similar renal function. We aimed to determine the differential effect of baseline, peak, and delta creatinine between genders on outcomes in infected hospitalized cirrhotic patients. North American Consortium for the Study of End-Stage Liver Disease is a 15-center consortium of tertiary care hepatology centers prospectively enrolling infected cirrhotic inpatients. Baseline, peak, and delta creatinine during hospitalization were compared between genders, and their impact on overall survival, transplant-free survival, probability of transplantation, and need for renal replacement therapy (RRT) was analyzed. In total, 532 patients with cirrhosis (males = 59% median admission MELD = 20) had significantly lower median baseline (1.07 vs. 1.30 mg/dL, p < 0.0001) and peak creatinine (1.47 vs. 1.59 mg/dL, p = 0.024) in women than men during hospitalization for an infection, but both genders had similar delta creatinine levels (0.30 vs. 0.30 mg/dL, p = 0.957). Thirty-day mortality was similar between genders. RRT was not used more often in women (19 vs. 12%, p = 0.050), and women were 1.8 times more likely than men to receive RRT at the same creatinine (p = 0.028). Both peak and delta creatinine significantly predicted 6-month overall and transplant-free survival (p < 0.0001), but the probability of liver transplantation was affected by the interaction between gender and both peak and delta creatinine. Infected hospitalized cirrhotic women are significantly more likely than men to receive RRT at similar creatinine levels. Gender-specific differences in baseline, peak, and delta creatinine need further investigation to determine whether women need acute kidney injury treatment at lower creatinine thresholds than men.

Reduced potassium excretion caused by angiotensin-converting enzyme inhibitors (ACEis) and angiotensin receptor blockers (ARBs) may increase the risk of hyperkalemia (serum potassium concentration >5 mmol/L) in the setting of increased potassium intake. The purpose of this study was to assess the effect of increasing dietary potassium on serum potassium concentration in hypertensive individuals with normal renal function treated with an ACEi or ARB. We hypothesized that an increase in dietary potassium would not provoke hyperkalemia in this population despite treatment with either an ACEi or ARB. We conducted a controlled, parallel-design clinical trial in 20 hypertensive subjects with normal renal function treated with an ACEi or ARB, with random assignment to a usual diet or a high-potassium diet (HKD). Fruit and vegetable intake was used to increase potassium intake. Serum potassium concentration, 3-d food records, and 24-h urine collections were completed at baseline and 4 wk. In the usual-diet group there were no statistically significant differences for potassium excretion, intake, or serum levels at end of study compared with baseline. The HKD group had significant differences in urinary potassium excretion (83 ± 26 mmol/d at baseline compared with 109 ± 35 mmol/d at 4 wk, P = 0.01) and dietary potassium intake (3775 ± 1189 mg/d at baseline compared with 5212 ± 1295 mg/d at 4 wk, P = 0.02). Despite increased potassium intake in the HKD group, serum potassium concentrations did not significantly increase from baseline at midpoint or end of study (4.1 ± 0.6, 4.3 ± 0.3, and 4.2 ± 0.4 mmol/L, respectively). This study demonstrates that an increase in dietary potassium over a 4-wk period is safe in hypertensive subjects who have normal renal function and are receiving ACEi and/or ARB therapy. This trial was registered at www.clinicaltrials.gov as NCT02759367. © 2016 American Society for Nutrition.

School meals provide an excellent opportunity to improve children's diet. To investigate dietary intakes and acceptance of nutritionally balanced school meals ("nutrimeals") as compared with regular ("baseline") school meals among Filipino students. The study employed a before-after intervention design with one group. Students 13 to 16 years of age from a public school in Metro Manila (n = 112) consumed baseline school meals for 2 weeks followed by consumption of nutri-meals for 7 weeks. Served meals and plate waste were weighed to calculate food and nutrient intakes. Acceptability of meals was assessed daily in a random subsample using a seven-point hedonic scale. Analysis of covariance corrected for age and sex was conducted to test for differences in nutrient intakes and acceptability between nutri-meals and baseline meals. Feeding nutri-meals resulted in a higher intake of vegetables (95.3 ± 13.8 g), fruit (76.5 ± 6.3 g), and fish (19.1 ± 3.3 g) than baseline meals. Energy and protein intakes significantly increased by 140.7 ± 2.8 kcal and 3.2 ± 0.1 g, respectively. The quality of fat intake improved compared with baseline meals (p < .001). Micronutrient intake from nutri-meals was significantly higher than that from baseline meals (except for zinc), contributing 6% to 79% of recommended daily intakes. Most students (> 90%) liked both baseline and nutrimeals; however, the mean acceptability score for baseline meals was slightly higher (0.2 ± 0.07 points, p = .004). Nutritionally balanced nutri-meals may be a healthier and acceptable alternative to regular Filipino school meals. Further optimization of nutri-meals is required to meet the nutritional needs of adolescents and reduce sodium content.

To evaluate baseline low-luminance visual acuity (LLVA) as a predictor of visual acuity improvement in patients with neovascular (wet) age-related macular degeneration (wAMD) receiving antivascular endothelial growth factor A (anti-VEGF) therapy. In the HARBOR trial, 1084 treatment-naïve patients ≥50 years of age with subfoveal wAMD received intravitreal ranibizumab 0.5 or 2.0 mg monthly or as needed. To measure LLVA, patients read a normally illuminated ETDRS (Early Treatment Diabetic Retinopathy Study) chart with a neutral density filter placed in front of the study eye. Patients were assigned into quartiles based on the magnitude of the difference between best-corrected visual acuity under optimal luminance (BCVA) and LLVA (BCVA-LLVA gap). The association between mean change in BCVA from baseline and BCVA-LLVA gap at baseline was analysed using a general linear model. A smaller baseline BCVA-LLVA gap predicted significantly higher BCVA gains over 24 months (p<0.0001 at each month; Pearson correlation), even after controlling for baseline BCVA or stratifying by treatment arm. Patients in the smallest baseline BCVA-LLVA gap quartile gained an average of +13.4 letters compared with +2.4 letters for patients in the widest baseline BCVA-LLVA gap quartile. At months 12 and 24, the smallest baseline BCVA-LLVA gap quartile had the highest proportion of ≥15-≥30-letter gain, and the widest baseline BCVA-LLVA gap quartile had the highest proportion of ≥15-/≥30-letter loss (p<0.0001; Fisher's exact test). The baseline BCVA-LLVA gap is a significant predictor of visual acuity response to anti-VEGF treatment in patients with wAMD. NCT00891735; Post-results. Published by the BMJ Publishing Group Limited.

The aim of this study was to evaluate the development of renal dysfunction in veterans with type 2 diabetes mellitus (T2DM) treated with different antidiabetic regimens. A retrospective cohort study involving 1715 patients with T2DM and baseline serum creatinine (SCr) of 1.5 mg/dL or lesser. The development of renal dysfunction, defined as 0.5 mg/dL or greater increase from baseline SCr during 4.8 years of follow-up with monotherapy metformin (M), 2 combination therapy groups: metformin + insulin (MI) and metformin + sulfonylurea (MS) users were compared with changes observed in sulfonylurea monotherapy users (S). Both MI and MS groups had higher mean baseline hemoglobin A1C (HbA1C) (9.0 and 8.6%, respectively) and higher rates of baseline macroalbuminuria (17.3 and 12.1%, respectively) as compared with M and S groups (mean HbA1C7.7% in both groups, and proteinuria M-5.1% and S-7.4%). In unadjusted analysis, the development of renal dysfunction was more frequent in MI and MS but not in M group as compared with sulfonylurea monotherapy (unadjusted HRs and [95% confidence interval (CI), 2.1[1.4-3.0], 1.4[1.1-1.9], and 1.0[0.6-1.7], respectively). However, differences in the development of renal dysfunction were not significant between the 4 groups after adjusting for baseline variables. Baseline macroalbuminuria was a strong predictor of Scr elevation of 0.5 mg/dL or greater during follow-up (adjusted HR, 3.1[1.9-4.7]). Unexpectedly, baseline use of renin-angiotensin-aldosterone system blockers was also associated with the development of renal dysfunction (adjusted HR, 1.9[1.3-2.8]). In this retrospective cohort study involving US predominantly male veterans with T2DM, baseline macroalbuminuria and use of RAAS blockers were associated with increased risk of development of renal dysfunction, whereas different antidiabetic regimens were not.

Whether direct-acting antiviral (DAA) therapy can reduce liver fibrosis and steatosis in patients with chronic hepatitis C virus (HCV) infection remains unclear. We evaluated sequential changes in liver stiffness and steatosis using transient elastography (TE) and the TE-based controlled attenuation parameter (CAP) in patients with HCV who received DAA therapy. A total of 57 patients with HCV who received DAA therapy and achieved sustained virological response (SVR) were analyzed. Liver stiffness as evaluated with TE, steatosis as evaluated with CAP, and laboratory data were assessed before treatment (baseline), at end of treatment (EOT), 24 weeks after EOT (SVR24), and 48 weeks after EOT (SVR48). Alanine aminotransferase levels, corresponding to the presence of necroinflammatory activity, significantly decreased overall, with significant differences between baseline and EOT, EOT, and SVR24, and baseline and SVR48. However, alanine aminotransferase levels showed no significant changes between SVR24 and SVR48. Median (interquartile range) liver stiffness values at baseline, EOT, SVR24, and SVR48 were 8.3 (5.0-14.8), 7.4 (4.6-14.7), 5.3 (4.1-11.8), and 5.4 (4.0-13.4) kPa, respectively (baseline vs. EOT, P=0.044; EOT vs. SVR24, P=0.011; and SVR24 vs. SVR48, P=0.054). In patients with fatty liver (CAP≥236 dB/m, n=14), CAP values at baseline and SVR48 were 253 (245-278) and 229 (209-249) dB/m, respectively (P=0.020). Liver stiffness at SVR24 might reflect liver fibrosis in the patients who received DAA therapy and achieved SVR. In addition, liver steatosis reduces in the same cohort with fatty liver.

The purpose was to assess the early effects of removable partial denture (RPD) placement on abutment teeth in patients with periodontal disease. Fifteen distal-extension RPDs and 19 abutment teeth were evaluated in 13 patients with moderate-to-severe periodontal diseases. Clinical periodontal records and grey level (GL) score based on digital subtraction radiography were measured on the day of denture placement (baseline) and at 1day, 1 week, 1 month, 3 months, and 6 months after the placement. Occlusal force on total dentition (Ft) and abutment tooth (Fa) were recorded with (baseline) and without denture on the day of the placement, and with denture in the follow-up examinations. No statistically significant difference between a follow-up period and the baseline was found in the clinical periodontal and occlusal force records, except for Ft with denture on the day of the placement, which was significantly lower than the baseline (p<0.05). The GL at distal crestal of the abutment was significantly higher at 1 week after the placement than at the baseline (p<0.05), while the scores of following examinations returned to the baseline level. The distal crestal bone of the abutment tooth transitorily reacts to mechanical stress due to the denture placement, while this does not suggest a detrimental effect within the limitation of the study design with a short-term observation period. The RPDs can be safely used for patients with periodontal diseases for at least 6 months if they are properly placed and maintained by professional care. Copyright © 2017 Elsevier Ltd.

Charcot foot is a rare but severe complication to diabetes and peripheral neuropathy. It is still unclear if an acute Charcot foot has long-term effects on the bone metabolism. To investigate this, we conducted a follow-up study to examine if a previously acute Charcot foot has any long-term effects on bone mineral density (BMD) or local or systemic bone metabolism. An 8.5-year follow-up case-control study of 44 individuals with diabetes mellitus, 24 of whom also had acute or chronic Charcot foot at the baseline visit in 2005-2007, who were followed up in 2015 with DXA scans and blood samples. 21 of the 44 baseline participants participated in the follow-up. There were no difference in the change in total hip BMD from baseline to follow-up in either the Charcot or the control group (p = 0.402 and 0.517), and no increased risk of osteoporosis in the previous Charcot feet either. From baseline to follow-up, there was a significant difference in the change in levels of fsRANK-L in the Charcot group, but not in the control group (p = 0.002 and 0.232, respectively). At follow-up, there were no differences in fsRANK-L between the groups. The fsRANK-L/OPG ratio also significantly decreased from baseline to follow-up in the Charcot group (3.4 versus 0.5) (p = 0.009), but not in the control group (1.3 versus 1.1) (p = 0.302). We found that diabetes patients with an acute Charcot foot have an elevated fsRANK-L/OPG ratio, and that the level decreased from baseline to follow-up to be comparable to the level in diabetes patients without previous or current Charcot foot. We found no permanent effect of an acute Charcot foot on hip or foot BMD. Copyright © 2017 Elsevier Inc. All rights reserved.

The US Surgeon General's Report on Bone Health suggests America's bone-health is in jeopardy and issued a "call to action" to develop bone-health plans that: (1) improve nutrition, (2) increase health literacy and, (3) increase physical activity. This study is a response to this call to action. After signing an informed consent, 158 adults agreed to follow an open-label bone-health plan for six months after taking a DXA test of bone density, a 43-chemistry blood test panel and a quality of life inventory (AlgaeCal 1). Two weeks after the last subject completed, a second group of 58 was enrolled and followed the identical plan, but with a different bone-health supplement (AlgaeCal 2). There were no significant differences between the two groups in baseline bone mineral density (BMD) or in variables related to BMD (age, sex, weight, percent body fat, fat mass, or fat-free mass). In both groups, no significant differences in BMD or related variables were found between volunteers and non-volunteers or between those who completed per protocol and those who were lost to attrition.Both groups experienced a significant positive mean annualized percent change (MAPC) in BMD compared to expectation [AlgaeCal 1: 1.15%, p = 0.001; AlgaeCal 2: 2.79%, p = 0.001]. Both groups experienced a positive MAPC compared to baseline, but only AlgaeCal 2 experienced a significant change [AlgaeCal 1: 0.48%, p = 0.14; AlgaeCal 2: 2.18%, p < 0.001]. The MAPC in AlgaeCal 2 was significantly greater than that in AlgaeCal 1 (p = 0.005). The MAPC contrast between compliant and partially compliant subjects was significant for both plans (p = 0.001 and p = 0.003 respectively). No clinically significant changes in a 43-panel blood chemistry test were found nor were there any changes in self-reported quality of life in either group. Following The Plan for six months with either version of the bone health supplement was associated with significant increases in BMD as compared to expected and, in AlgaeCal 2, the increase from baseline was significantly greater than the increase from baseline in AlgaeCal 1. Increased compliance was associated with greater increases in BMD in both groups. No adverse effects were reported in either group. ClinicalTrials.gov NCT01114685.

Objectives. We assessed the relationship between alcohol consumption in young adulthood (ages 18–30 years) and occupational success 15 years later among Blacks and Whites. Methods. We analyzed data from the Coronary Artery Risk Development in Young Adults Study on employment status and occupational prestige at year 15 from baseline. The primary predictor was weekly alcohol use at baseline, after stratification by race and adjustment for socioeconomic factors. Results. We detected racial differences in the relationship between alcohol use in early adulthood and employment status at midlife. Blacks who were very heavy drinkers at baseline were more than 4 times as likely as Blacks who were occasional drinkers to be unemployed at year 15 (odds ratio [OR] = 4.34; 95% confidence interval [CI] = 2.22, 8.47). We found no statistically significant relationship among Whites. Occupational prestige at midlife was negatively related to very heavy drinking, but after adjustment for marital status, active coping, life stress, and educational attainment, this relationship was statistically significant only among Blacks. Conclusions. Heavy drinking during young adulthood was negatively associated with labor market success at midlife, especially among Blacks. PMID:19834006

in advanced cancer patients a cell-mediated immunological impairment, both at baseline and during postoperative period (surgical trauma response) is often found and is associated with poor prognosis. Furthermore it is well known that cortisol is strictly involved in the response to major surgical stress, has an important immunosuppression activity and causes a redistribution of immunological population cells in different tissues. The aim of the study was to verify serum levels and circadian rhythm of cortisol and ACTH in patients with colorectal cancer at baseline before surgery and in the postoperative period, and relate it to the immune status. 40 patients (22 female, 18 male with a median age of 66 yrs) with histologically proven colorectal cancer undergoing to surgery were enrolled in the study. Assessment of total lymphocyte, CD4+, cortisol level, circadian rhythm of cortisol (11 pm and 8 am) was performed at baseline and in 3rd and 7th postoperative days. ACTH levels (11 pm and 8 am) were studied in 18 patients. increase of cortisol serum level in the post-operative period vs baseline was statistically significant both in 3rd and 7th days. A significant decrease of total and CD4+ lymphocytes count was found on both 3rd and 7th postoperative days compared to baseline and to normal values. The rate of patients with an altered circadian rhythm was 68% and 53% at 3rd and 7th postoperative days respectively. At baseline 28% of patients had an altered cortisol circadian rhythm and it was significantly more frequent in patients with nodal involvement (P<0.005) and with metastatic spread (P<0.004). 44% of 18 patients evaluated for ACTH circadian rhythm displayed an alteration and it was significantly higher in patients with nodal involvement and metastatic disease (P<0.05). No relations between lymphocytopenia and alteration of night-cortisolemy, day-cortisolemy and cortisol and ACTH circadian rhythm were found, neither at baseline, 3rd and 7th postoperative days. it is known that lymphocytopenia, both at baseline and in the postoperative period, is associated with a poor prognosis in cancer patients and that cortisol plays an important role in the immune response. Our data show that lymphocytopenia often present in cancer patients, poor prognostic factor, seems not to be associated with ACTH and cortisol level and circadian rhythm alteration, both at baseline and after surgical stress. Otherwise even if paraneoplastic syndromes seems not to be related to colorectal cancer and no patient showed adrenocortical metastasis, an impairment of circadian rhythm of cortisol and ACTH was found at baseline in 28% and 44% respectively. It was significantly associated with the presence of metastatic disease. These preliminary results suggest further investigations on relation between cancer and endocrine system.

In the present study, we aimed to determine whether game-based virtual reality (VR) rehabilitation, combined with occupational therapy (OT), could improve health-related quality of life, depression, and upper extremity function. We recruited 35 patients with chronic hemiparetic stroke, and these participants were randomized into groups that underwent VR rehabilitation plus conventional OT, or the same amount of conventional OT alone, for 20 sessions over 4 weeks. Compared to baseline, the VR rehabilitation plus OT group exhibited significantly improved role limitation due to emotional problems (p=0.047). Compared to baseline, both groups also exhibited significantly improved depression (p=0.017) and upper extremity function (p=0.001), although the inter-group differences were not significant. However, a significant inter-group difference was observed for role limitation due to physical problems (p=0.031). Our results indicate that game-based VR rehabilitation has specific effects on health-related quality of life, depression, and upper extremity function among patients with chronic hemiparetic stroke.

To investigate baseline demographics and disease characteristics as predictors of the analgesic effect of duloxetine and pregabalin on diabetic peripheral neuropathic pain (DPNP). Based on data from the COMBO-DN study, a multinational clinical trial in DPNP, the potential impact of baseline characteristics on pain relief after 8-week monotherapy with 60 mg/day duloxetine or 300 mg/day pregabalin was assessed using analyses of covariance. Subgroups of interest were characterized regarding their baseline characteristics and efficacy outcomes. A total of 804 patients were evaluated at baseline. A significant interaction with treatment was observed in the mood symptom subgroups with a larger pain reduction in duloxetine-treated patients having no mood symptoms [Hospital Anxiety and Depression Scale (HADS) depression or anxiety subscale score <11; -2.33 (duloxetine); -1.52 (pregabalin); p = 0.024]. There were no significant interactions between treatment for subgroups by age (<65 or ≥65 years), gender, baseline pain severity [Brief Pain Inventory Modified Short Form (BPI-MSF) average pain <6 or ≥6], diabetic neuropathy duration (≤2 or >2 years), baseline haemoglobin A1c (HbA1c) (<8% or ≥8%), presence of comorbidities and concomitant medication use. Our analyses suggest that the efficacy of duloxetine and pregabalin for initial 8-week treatment in DPNP was consistent across examined subgroups based on demographics and disease characteristics at baseline except for the presence of mood symptoms. Duloxetine treatment appeared to be particularly beneficial in DPNP patients having no mood symptoms. © 2015 European Pain Federation - EFIC®

To assess the validity and reliability of the infrared spectrometry for measuring the delta over baseline for breath 13C. Twenty-four healthy adults were selected, including twelve males and twelve females. 13C-Leucine was used as tracer in stable isotope metabolic experiments. One baseline breath was collected before the tracer protocol began. Other breath samples were collected at 60, 120, 180, 195, 210, 225, 240, 255, 270 and 300 min post-tracer challenge. The delta over baseline for breath 13C was measured by the infrared spectrometry and Heliview 13C breath analyzer. No significant differences were found between the infrared spectrometry and Heliview 13C breath analyzer in measuring the delta over baseline for breath 13C. The F value and p value of two-way ANOVA were 0.29 and 0.5874 respectively. The t and p value of consistency test were 0.48 and 0.6346 respectively. The 13C infrared spectrometry can reliably measure the delta over baseline for breath 13C.

To evaluate the opaquing capacity, color compatibility and stability of IPS Empress all-ceramic veneers. A total of 86 IPS Empress all-ceramic veneers were made for 18 patients. The patients were divided into three groups: Group A was tetracycline teeth, 64 veneers for 5 patients; Group B was non-tetracycline teeth, 22 veneers for 13 patients; Group C was 22 natural vital teeth with normal color as control group. Before and after veneers were inserted, ShadeEye NCC was employed to obtain L * a * b * values of each tooth. The values of cemented veneers used as the baseline, the L * a * b * values of each veneer were measured half a year, 1 year, and 2 years after restoration respectively. All L * a * b * values at different evaluation times were analyzed by SPSS 10.0. Before and after veneers were restored, the L * a * b * values of both Group A and Group B were significantly different, the color difference being 5.01 and 4.15 respectively. The color difference between Group A and selected shade guides was 2.45. Compared with the baseline value, the L * value of Group A significantly decreased 2 years after restoration, but the DeltaE of different evaluation times was not significantly different. The color difference between Group B and Group C was 0.22 and there was no significant color difference after restoration. IPS Empress all-ceramic veneers have excellent opaquing capacity, color compatibility and stability to non-tetracycline teeth. To tetracycline teeth IPS Empress all-ceramic veneers have a certain opaquing capacity, but they cannot completely match with shade guides; the L * value is significantly different after restoration and further studies are needed to evaluate its color effect.

Objective Statins inhibit cholesterol synthesis but can upregulate cholesterol absorption, with higher doses producing larger effects. Ezetimibe inhibits cholesterol absorption but also upregulates synthesis. We tested whether ezetimibe added to ongoing statin therapy would be most effective in lowering LDL-cholesterol (LDL-C) in subjects on high-potency statins and whether these effects would be related to alterations in cholesterol absorption (β-sitosterol) and synthesis (lathosterol) markers. Methods Hypercholesterolemic subjects (n=874) on statins received ezetimibe 10 mg/day. Plasma lipids, lathosterol, and β-sitosterol were measured at baseline and on treatment. Subjects were divided into low- (n=133), medium- (n=582), and high- (n=159) statin potency groups defined by predicted LDL-C–lowering effects of each ongoing statin type and dose (reductions of ~20-30%, ~31-45%, or ~46-55%, respectively). Results The high-potency group had significantly lower baseline lathosterol (1.93 vs. 2.58 vs. 3.17 μmol/l; p <0.001) and higher baseline β-sitosterol values (6.21 vs. 4.58 vs. 4.51 μmol/l, p <0.001) than medium-/low-potency groups. Ezetimibe treatment in the high-potency group produced significantly greater reductions from baseline in LDL-C than medium-/low-potency groups (−29.1% vs. −25.0% vs. −22.7%; p <0.001) when evaluating unadjusted data. These effects and group differences were significantly (p <0.05) related to greater β-sitosterol reductions and smaller lathosterol increases. However, LDL-C reduction differences between groups were no longer significant after controlling for placebo effects, due mainly to modest LDL-C lowering by placebo in the high-potency group. Conclusion Patients on high-potency statins have the lowest levels of cholesterol synthesis markers and the highest levels of cholesterol absorption markers at baseline, and the greatest reduction in absorption markers and the smallest increases in synthesis markers with ezetimibe addition. Therefore, such patients may be good candidates for ezetimibe therapy if additional LDL-C lowering is needed. PMID:23040830

This study explored the relationship between serum ferritin and hepcidin in athletes. Baseline serum ferritin levels of 54 athletes from the control trial of five investigations conducted in our laboratory were considered; athletes were grouped according to values <30 μg/L (SF<30), 30–50 μg/L (SF30–50), 50–100 μg/L (SF50–100), or >100 μg/L (SF>100). Data pooling resulted in each athlete completing one of five running sessions: (1) 8×3 min at 85% vVO2peak; (2) 5×4 min at 90% vVO2peak; (3) 90 min continuous at 75% vVO2peak; (4) 40 min continuous at 75% vVO2peak; (5) 40 min continuous at 65% vVO2peak. Athletes from each running session were represented amongst all four groups; hence, the mean exercise duration and intensity were not different (p>0.05). Venous blood samples were collected pre-, post- and 3 h post-exercise, and were analysed for serum ferritin, iron, interleukin-6 (IL-6) and hepcidin-25. Baseline and post-exercise serum ferritin levels were different between groups (p<0.05). There were no group differences for pre- or post-exercise serum iron or IL-6 (p>0.05). Post-exercise IL-6 was significantly elevated compared to baseline within each group (p<0.05). Pre- and 3 h post-exercise hepcidin-25 was sequentially greater as the groups baseline serum ferritin levels increased (p<0.05). However, post-exercise hepcidin levels were only significantly elevated in three groups (SF30–50, SF50–100, and SF>100; p<0.05). An athlete's iron stores may dictate the baseline hepcidin levels and the magnitude of post-exercise hepcidin response. Low iron stores suppressed post-exercise hepcidin, seemingly overriding any inflammatory-driven increases. PMID:24667393

Nikseresht, M. Comparison of serum cytokine levels in men who are obese or men who are lean: effects of nonlinear periodized resistance training and obesity. J Strength Cond Res 32(6): 1787-1795, 2018-This study examined the capacity of nonlinear resistance training (NRT) to alter some cytokines and markers of insulin resistance in men who are obese. An additional aim was to compare these variables between men who are obese and men who are lean. Age- and fitness-matched men who are obese were randomly allocated to NRT (n = 12) and control (CON, n = 10) groups. An age- and fitness-matched control group of lean men (n = 11) were also recruited for baseline comparison. The NRT (12 weeks, 3 d·wk, 5-11 exercises) performed at different intensities (40-95% of 1 repetition maximum) with flexible periodization. Serum insulin, glucose, interleukin (IL)-6, IL-10, IL-17A, and IL-20 levels were measured at baseline and after training. Men who were obese had significantly lower IL-20 and higher glucose, insulin, insulin resistance (homeostasis model assessment, HOMA-IR), IL-10, and IL-6 than lean participants at baseline (all, p ≤ 0.05). There were significant negative correlations between IL-10 with anthropometric markers and HOMA-IR at baseline, whereas these variables were inversely correlated with IL-20. After training, V[Combining Dot Above]O2peak and 1 repetition maximum for bench press and knee extension of the NRT increased significantly compared with CON, which was accompanied by significant reductions in anthropometric markers, insulin and HOMA-IR. IL-6 and IL-17A did not change significantly in response to training, but IL-10 and IL-20 increased significantly compared with baseline. An inverse relationship between the percent IL-20 increase and the percent waist circumference decrease suggests that adipocytes, or other metabolic factors such as glucose, may exert a lowering-effect on IL-20.

HIV and TB infections are both associated with elevated oxidative stress parameters. Anti-oxidant supplementation may offer beneficial effects in positively modulating oxidative stress parameters in HIV and HIV-TB infected patients. We investigated the effects of vitamin A and C supplementation on oxidative stress in HIV infected and HIV-TB co-infected subjects. 40 HIV/TB co-infected and 50 HIV mono-infected patients were divided into 2 equal groups. Participants provided demographic information and blood was collected to determine oxidative stress parameters before and after vitamin A (5000 IU) and C (2600 mg) supplementation for 1 month. There was a significantly (p < 0.05) higher level of Malondialdehyde (MDA) at baseline for HIV infected subjects compared with HIV-TB co-infected subjects. There was a significantly (p < 0.05) lower level of MDA and higher level of Catalase (CAT) in subjects administered supplementation compared to subjects without supplementation for the HIV infected group. There was a significantly lower level of Reduced Glutathione (GSH), Superoxide Dismutase (SOD) and higher level of MDA after one month of supplementation compared with baseline levels for HIV/TB co infected subjects. A similar result was also obtained for the HIV mono-infected groups which had a significantly lower level of SOD, MDA and CAT compared to the baseline. There was a significantly lower level of GSH and SOD, and higher level of MDA after supplementation compared with the baseline for HIV/TB co-infected subjects. Comparing the indices at baseline and post no-supplementation in HIV/TB co-infection showed no significant differences in the oxidative stress parameters. HIV/TB co-infection and HIV mono-infection seems to diminish the capacity of the anti-oxidant system to control oxidative stress, however exogenous anti-oxidant supplementation appears not to have beneficial roles in positively modulating the associated oxidative stress.

Interleukin 13 (IL-13) is thought to play a key role as an effector cytokine in UC. Anrukinzumab, a humanised antibody that inhibits human IL-13, was evaluated for the treatment of UC. In a multicentre, randomised, double-blind, placebo-controlled study, patients with active UC (Mayo score ≥4 and <10) were randomised to anrukinzumab 200, 400 or 600 mg or placebo. Patients received five intravenous administrations over 14 weeks. The primary endpoint was fold change from baseline in faecal calprotectin (FC) at Week 14. Secondary endpoints included safety, pharmacokinetics and IL-13 levels. The modified intention-to-treat population included 84 patients (21 patients/arm). Fold change of FC from baseline at Week 14 was not significantly different for any treatment groups compared with the placebo. The study had a high dropout rate, in part, related to lack of efficacy. The exploratory comparisons of each dose were not significantly different from placebo in terms of change from baseline in total Mayo score, clinical response, clinical remission and proportion of subjects with mucosal healing. An increase in serum total IL-13 (free and bound to anrukinzumab) was observed for all anrukinzumab groups but not with placebo. This suggests significant binding of anrukinzumab to IL-13. The safety profile was not different between the anrukinzumab and placebo groups. A statistically significant therapeutic effect of anrukinzumab could not be demonstrated in patients with active UC in spite of binding of anrukinzumab to IL-13.

The SERVE-HF trial investigated the impact of treating central sleep apnoea (CSA) with adaptive servo-ventilation (ASV) in patients with systolic heart failure. A preplanned substudy was conducted to provide insight into mechanistic changes underlying the observed effects of ASV, including assessment of changes in left ventricular function, ventricular remodelling, and cardiac, renal and inflammatory biomarkers. In a subset of the 1325 randomised patients, echocardiography, cardiac magnetic resonance imaging (cMRI) and biomarker analysis were performed at baseline, and 3 and 12 months. In secondary analyses, data for patients with baseline and 12-month values were evaluated; 312 patients participated in the substudy. The primary endpoint, change in echocardiographically determined left ventricular ejection fraction from baseline to 12 months, did not differ significantly between the ASV and the control groups. There were also no significant between-group differences for changes in left ventricular dimensions, wall thickness, diastolic function or right ventricular dimensions and ejection fraction (echocardiography), and on cMRI (in small patient numbers). Plasma N-terminal pro B-type natriuretic peptide concentration decreased in both groups, and values were similar at 12 months. There were no significant between-group differences in changes in cardiac, renal and systemic inflammation biomarkers. In patients with systolic heart failure and CSA, addition of ASV to guideline-based medical management had no statistically significant effect on cardiac structure and function, or on cardiac biomarkers, renal function and systemic inflammation over 12 months. The increased cardiovascular mortality reported in SERVE-HF may not be related to adverse remodelling or worsening heart failure. © 2017 The Authors.

Rifaximin, a nonabsorbable antibiotic that decreases lipopolysaccharide (LPS) in cirrhotics, may decrease the elevated levels of microbial translocation, T-cell activation and inflammation in human immunodeficiency virus (HIV)-positive immune nonresponders to antiretroviral therapy (ART). HIV-positive adults receiving ART for ≥96 weeks with undetectable viremia for ≥48 weeks and CD4(+) T-cell counts <350 cells/mm(3) were randomized 2:1 to rifaximin versus no study treatment for 4 weeks. T-cell activation, LPS, and soluble CD14 were measured at baseline and at weeks 2, 4, and 8. Wilcoxon rank sum tests compared changes between arms. Compared with no study treatment (n = 22), rifaximin (n = 43) use was associated with a significant difference between study arms in the change from baseline to week 4 for CD8(+)T-cell activation (median change, 0.0% with rifaximin vs +0.6% with no treatment; P = .03). This difference was driven by an increase in the no-study-treatment arm because there was no significant change within the rifaximin arm. Similarly, although there were significant differences between study arms in change from baseline to week 2 for LPS and soluble CD14, there were no significant changes within the rifaximin arm. In immune nonresponders to ART, rifaximin minimally affected microbial translocation and CD8(+)T-cell activation. Trial registration number. NCT01466595. © The Author 2014.

Aim The effects of atomoxetine (20 and 60 mg twice daily), 400 mg moxifloxacin and placebo on QTc in 131 healthy CYP2D6 poor metabolizer males were compared. Methods Atomoxetine doses were selected to result in plasma concentrations that approximated expected plasma concentrations at both the maximum recommended dose and at a supratherapeutic dose in CYP2D6 extensive metabolizers. Ten second electrocardiograms were obtained for time-matched baseline on days −2 and −1, three time points after dosing on day 1 for moxifloxacin and five time points on day 7 for atomoxetine and placebo. Maximum mean placebo-subtracted change from baseline model-corrected QT (QTcM) on day 7 was the primary endpoint. Results QTcM differences for atomoxetine 20 and 60 mg twice daily were 0.5 ms (upper bound of the one-sided 95% confidence interval 2.2 ms) and 4.2 ms (upper bound of the one-sided 95% confidence interval 6.0 ms), respectively. As plasma concentration of atomoxetine increased, a statistically significant increase in QTc was observed. The moxifloxacin difference from placebo met the a priori definition of non-inferiority. Maximum mean placebo-subtracted change from baseline QTcM for moxifloxacin was 4.8 ms and this difference was statistically significant. Moxifloxacin plasma concentrations were below the concentrations expected from the literature. However, the slope of the plasma concentration−QTc change observed was consistent with the literature. Conclusion Atomoxetine was not associated with a clinically significant change in QTc. However, a statistically significant increase in QTc was associated with increasing plasma concentrations.

Metabolic syndrome poses additional risk for postmenopausal women who are already at risk for osteoporosis. We hypothesized that a nutritional supplement containing anti-inflammatory phytochemicals and essential bone nutrients would produce a favorable bone biomarker profile in postmenopausal women with metabolic syndrome. In this 14-week, randomized trial, 51 women were instructed to consume a modified Mediterranean-style, low-glycemic-load diet and to engage in aerobic exercise. Those in the intervention arm (n = 25) additionally received 200 mg hop rho iso-alpha acids, 100 mg berberine sulfate trihydrate, 500 IU vitamin D₃, and 500 μg vitamin K₁ twice daily. Forty-five women completed the study. Baseline nutrient intake did not differ between arms. Compared with baseline, the intervention arm exhibited an approximate 25% mean decrease (P < .001) in serum osteocalcin (indicative of bone turnover), whereas the placebo arm exhibited a 21% increase (P = .003). Serum 25-hydroxyvitamin D increased 23% (P = .001) in the intervention arm and decreased 12% (P = .03) in the placebo arm. The between-arm differences for osteocalcin and 25-hydroxyvitamin D were statistically significant. Serum insulin-like growth factor I was statistically increased in both arms, but the between-arm differences were not statistically significant. Subanalysis showed that among those in the highest tertile of baseline insulin-like growth factor I, the intervention arm exhibited a significant increase in amino-terminal propeptide of type I collagen, whereas the placebo arm showed a significant decrease at 14 weeks. Treatment with rho iso-alpha acids, berberine, vitamin D₃, and vitamin K₁ produced a more favorable bone biomarker profile indicative of healthy bone metabolism in postmenopausal women with metabolic syndrome.

To evaluate the relationship between alcohol consumption and the risk of acute exacerbation of COPD (AECOPD). We conducted a secondary analysis of data previously collected in a large, multicenter trial of daily azithromycin in COPD. To analyze the relationship between amount of baseline self-reported alcohol consumption in the past 12 months and subsequent AECOPD, we categorized the subjects as minimal (<1 drink/month), light-to-moderate (1-60 drinks/month), or heavy alcohol users (>60 drinks/month). The primary outcome was time to first AECOPD and the secondary outcome was AECOPD rate during the 1-year study period. Of the 1,142 enrolled participants, 1,082 completed baseline alcohol questionnaires and were included in this analysis. Six hundred and forty-five participants reported minimal alcohol intake, 363 reported light-to-moderate intake, and 74 reported heavy intake. There were no statistically significant differences in median time to first AECOPD among minimal (195 days), light-to-moderate (241 days), and heavy drinkers (288 days) (P=0.11). The mean crude rate of AECOPD did not significantly differ between minimal (1.62 events per year) and light-to-moderate (1.44 events per year) (P=0.095), or heavy drinkers (1.68 events per year) (P=0.796). There were no significant differences in hazard ratios for AECOPD after adjustment for multiple covariates. Among persons with COPD at high risk of exacerbation, we found no significant relationship between self-reported baseline alcohol intake and subsequent exacerbations. The number of patients reporting heavy alcohol intake was small and further study is needed to determine the effect of heavy alcohol intake on AECOPD risk.

Objective To investigate vilazodone, currently approved for major depressive disorder in adults, for generalized anxiety disorder (GAD). Method Three randomized, double-blind, placebo-controlled studies showing positive results for vilazodone (2,040 mg/d) in adult patients with GAD (DSM-IV-TR) were pooled for analyses; data were collected from June 2012 to March 2014. Post hoc outcomes in the pooled intent-to-treat population (n = 1,462) included mean change from baseline to week 8 in Hamilton Anxiety Rating Scale (HARS) total score, psychic and somatic anxiety subscale scores, and individual item scores; HARS response (≥ 50% total score improvement) and remission (total score ≤ 7) at week 8; and category shifts, defined as HARS item score ≥ 2 at baseline (moderate to very severe symptoms) and score of 0 at week 8 (no symptoms). Results The least squares mean difference was statistically significant for vilazodone versus placebo in change from baseline to week 8 in HARS total score (−1.83, P < .0001) and in psychic anxiety (−1.21, P < .0001) and somatic anxiety (−0.63, P < .01) subscale scores; differences from placebo were significant on 11 of 14 HARS items (P < .05). Response rates were higher with vilazodone than placebo (48% vs 39%, P < .001), as were remission rates (27% vs 21%, P < .01). The percentage of patients who shifted to no symptoms was significant for vilazodone on several items: anxious mood, tension, intellectual, depressed mood, somatic-muscular, somatic-sensory, cardiovascular, respiratory, and autonomic symptoms (P < .05). Conclusions Treatment with vilazodone versus placebo was effective in adult GAD patients, with significant differences between treatment groups found on both psychic and somatic HARS items.

Prescribed, patient-applied tooth lightening agents, or nightguard vital bleaching, typically utilizes a 10% carbamide peroxide agent applied during nocturnal hours. The purpose of this randomized double-blind study was to compare the amount of tooth color change in two groups of subjects using dentist-supervised, patient-applied 10% carbamide peroxide gel. One group used Opalescence (Ultradent Products Inc., South Jordan, Utah) and the other NiteWhite Excel (Discus Dental, Inc., Los Angeles, California). Evaluation of tooth color for the six maxillary anterior teeth was done using a Vita shade guide at baseline, 1, 2, and 4 weeks. Subjects were instructed to apply the gel nocturnally using a custom-made soft tray 8 hours per day for 2 weeks. The 16 tabs of the shade guide were ranked according to value from darkest to lightest. The number (1-16) that correlated to the shade tab selected as the match for each tooth was the outcome variable. A Kruskal-Wallis one way analysis of variance on ranks was used. The test revealed no statistically significant difference between Opalescence and NiteWhite Excel for lightening the teeth (p = .807). The color change was still significant after 2 weeks without further bleaching activity. The baseline evaluation of the maxillary incisors and canines for all subjects, regardless of group, demonstrated a significant shade difference, with the canines being darker. This difference was not seen after 2 weeks of active bleaching or at the 4-week evaluation. In this study comparing bleaching products, patients using Opalescence and NiteWhite Excel experienced a significant change in the color of their teeth relative to baseline values after 2 weeks of active treatment.

Sedentary time is an independent risk factor for chronic diseases and mortality. It is unknown whether active adults alter their dietary and/or physical activity behaviors in response to imposed sedentary time, possibly modifying risk. The aim of this study was to determine whether imposed sedentary time would alter typical behaviors of active adults. Sixteen physically active, young adults were randomized to the no-intervention control (CON, n = 8) group or the sedentary-intervention (SIT, n = 8) group. SIT participants attended monitored sedentary sessions (8 wk, 10 h/wk). Assessments including diet and physical activity occurred at baseline, week 4, and week 9. There were no differences (P > .05) between CON and SIT groups for step counts or time spent in sedentary, light, moderate, or vigorous physical activity when comparing a week during imposed sedentary time (week 4) to baseline and week 9. At week 4, caloric intake was not different from baseline (P > .05) in either group. Caloric intake decreased significantly (P > .05) in SIT from baseline to week 9. Active adults did not alter physical activity or dietary behaviors during the imposed sedentary intervention. However, SIT reduced caloric intake from baseline to week 9, indicating a possible compensatory response to imposed sitting in active adults.

Accumulating evidence suggests an important role for psychosocial work factors in injury, but little is known about the interaction between psychosocial factors and previous injury experience on subsequent injury risk. We examined the relationships between psychosocial work factors and new or recurrent injury among hospital workers. We studied 492 hospital workers including 116 cases with baseline injury and 376 injury-free referents at baseline over follow-up. Job strain, total support, effort-reward imbalance, overcommitment, and musculoskeletal injury at baseline were examined in logistic regression models as predictors of new or recurrent injury experienced during a 2-year follow-up period. The overall cumulative incidence of injury over follow-up was 35.6 % (51.7 % for re-injury among baseline injury cases; 30.6 % for new injury among referents). Significantly increased risks with baseline job strain (OR 1.26; 95 % CI 1.02-1.55) and effort-reward imbalance (OR 1.42; 95 % CI 1.12-1.81) were observed for injury only among the referents. Overcommitment was associated with increased risk of injury only among the cases (OR 1.58; 95 % CI 1.05-2.39). The effects of psychosocial work factors on new or recurrent injury risk appear to differ by previous injury experience, suggesting the need for differing preventive strategies in hospital workers.
Relative peripheral refraction in children: twelve-month changes in eyes with different ametropias.
Lee, Tsui-Tsui; Cho, Pauline
2013-05-01
To determine the peripheral refraction of children with different types of ametropias and to evaluate the relationship between central refractive changes, baseline relative peripheral refraction (RPR) and changes in RPR over a 12-month monitoring period. Cycloplegic central and peripheral refraction were performed biannually on the right eyes of children aged 6-9 for 12 months, using an open-view autorefractor. Peripheral refraction were measured along 10°, 20° and 30° from central fixation in both nasal and temporal fields. Refractive data were transposed into M, J0 and J45 vectors for analyses. RPR was determined by subtracting the central measurement from each peripheral measurement. Hyperopic eyes showed relative peripheral myopia while myopic eyes had relative hyperopia across the central 60° horizontal field at baseline. Emmetropic eyes had relative myopia within but showed relative hyperopia beyond the central 30° field. However, there was no significant correlation between central refractive changes and baseline RPR or between changes in central refraction and RPR over twelve months in any refractive groups. Correlations between changes in PR and central myopic shift were found mainly in the nasal field in different groups. In the subgroup analysis on the initially emmetropic and the initially myopic groups, the subgroups with faster myopic progression did not have significantly different RPR from the subgroups with slower progression. The RPR pattern of the initially emmetropic and the initially myopic groups became more asymmetric at the end of the study period with a larger increase in relative hyperopia in the temporal field. RPR patterns were different among hyperopic, emmetropic and myopic eyes. However, baseline RPR and changes in RPR cannot predict changes in central refraction over time. Our results did not provide evidence to support the hypothesis of RPR as a causative factor for myopic central refractive changes in children.

White matter and memory in healthy adults: Coupled changes over two years.
Bender, Andrew R; Prindle, John J; Brandmaier, Andreas M; Raz, Naftali
2016-05-01
Numerous cross-sectional studies have used diffusion tensor imaging (DTI) to link age-related differences in white matter (WM) anisotropy and concomitant decrements in cognitive ability. Due to a dearth of longitudinal evidence, the relationship between changes in diffusion properties of WM and cognitive performance remains unclear. Here we examine the relationship between two-year changes in WM organization and cognitive performance in healthy adults (N=96, age range at baseline=18-79 years). We used latent change score models (LCSM) to evaluate changes in age-sensitive cognitive abilities - fluid intelligence and associative memory. WM changes were assessed by fractional anisotropy (FA), axial diffusivity (AD), and radial diffusivity (RD) in WM regions that are considered part of established memory networks and exhibited individual differences in change. In modeling change, we postulated reciprocal paths between baseline measures and change factors, within and between WM and cognition domains, and accounted for individual differences in baseline age. Although baseline cross-sectional memory performance was positively associated with FA and negatively with RD, longitudinal effects told an altogether different story. Independent of age, longitudinal improvements in associative memory were significantly associated with linear reductions in FA and increases in RD. The present findings demonstrate the sensitivity of DTI-derived indices to changes in the brain and cognition and affirm the importance of longitudinal models for evaluating brain-cognition relations.

Oral cholera vaccines (OCVs) are relatively new public health interventions, and limited data exist on the potential impact of OCV use on traditional cholera prevention and control measures—safe water, sanitation and hygiene (WaSH). To assess OCV acceptability and knowledge, attitudes, and practices (KAPs) regarding cholera and WaSH, we conducted cross-sectional surveys, 1 month before (baseline) and 3 and 12 months after (first and second follow-up) a preemptive OCV campaign in Maela, a long-standing refugee camp on the Thailand-Burma border. We randomly selected households for the surveys, and administered questionnaires to female heads of households. In total, 271 (77%), 187 (81%), and 199 (85%) households were included in the baseline, first and second follow-up surveys, respectively. Anticipated OCV acceptability was 97% at baseline, and 91% and 85% of household members were reported to have received 1 and 2 OCV doses at first follow-up. Compared with baseline, statistically significant differences (95% Wald confidence interval not overlapping zero) were noted at first and second follow-up among the proportions of respondents who correctly identified two or more means of cholera prevention (62% versus 78% and 80%), reported boiling or treating drinking water (19% versus 44% and 69%), and washing hands with soap (66% versus 77% and 85%); a significant difference was also observed in the proportion of households with soap available at handwashing areas (84% versus 90% and 95%), consistent with reported behaviors. No significant difference was noted in the proportion of households testing positive for Escherichia coli in stored household drinking water at second follow-up (39% versus 49% and 34%). Overall, we observed some positive, and no negative changes in cholera- and WaSH-related KAPs after an OCV campaign in Maela refugee camp. OCV campaigns may provide opportunities to reinforce beneficial WaSH-related KAPs for comprehensive cholera prevention and control. PMID:27992609

Compared with baseline, statistically significant differences (95% Wald confidence interval not overlapping zero) were noted at first and second follow-up among the proportions of respondents who correctly identified two or more means of cholera prevention (62% versus 78% and 80%), reported boiling or treating drinking water (19% versus 44% and 69%), and washing hands with soap (66% versus 77% and 85%); a significant difference was also observed in the proportion of households with soap available at handwashing areas (84% versus 90% and 95%), consistent with reported behaviors. No significant difference was noted in the proportion of households testing positive for Escherichia coli in stored household drinking water at second follow-up (39% versus 49% and 34%). Overall, we observed some positive, and no negative changes in cholera- and WaSH-related KAPs after an OCV campaign in Maela refugee camp. OCV campaigns may provide opportunities to reinforce beneficial WaSH-related KAPs for comprehensive cholera prevention and control.

To assess the extent and duration of the effect of tongue cleaning procedures on bacterial load on the dorsal surface of the tongue. 19 subjects participated in this blinded crossover study. Subjects abstained from oral hygiene, eating and drinking from 22:00 h the previous evening. Tongue samples were collected at baseline and within 15 minutes of one of three procedures: teeth brushing alone; teeth brushing plus tongue scraping; teeth brushing plus tongue cleaning using a high speed vacuum ejector and irrigation with 20 ml antibacterial mouthwash. Subjects then brushed twice daily for 3 days apart from the second group who additionally scraped their tongue twice daily. On day 4, baseline and post-treatment samples were collected as per day 1. Bacteria (total anaerobes, Gram-negative anaerobes, VSC-producing bacteria and Streptococcus saliuarius) were enumerated using appropriate selective media. The tongue dorsum was colonized by all 4 bacterial categories (log(10) 6-8 cfu/sample). For subjects who brushed their teeth only, there was a significant reduction from baseline for S. saliuarius only. In contrast, tooth brushing plus tongue scraping resulted in statistically significant reductions from baseline for all bacterial categories (range log(10) 0.11-0.40 cfu/sample). Highly statistically significant reductions (log(10) 1.11-1.96 cfu/sample) were observed for subjects who underwent thorough tongue cleaning with the saliva ejector/mouthwash. To determine longevity of treatment effects, baseline bacterial loads for days 1 and 4 were compared. Only daily tongue scraping resulted in statistical significant reduction in baseline microbial loads on day 4. While mechanical tongue cleaning with or without chemical intervention can reduce bacterial load on the tongue, this effect is transient, and regular tongue cleaning is required to provide a long lasting (overnight) reduction in bacterial numbers. Nevertheless, tongue cleaning is an oral hygiene procedure that is little practiced due to discomfort and/or lack of awareness on the part of dental professionals and their patients.

We have examined the relationship between artificially sweetened beverage (ASB) consumption and long-term weight gain in the San Antonio Heart Study. From 1979 to 1988, height, weight, and ASB consumption were measured among 5,158 adult residents of San Antonio, Texas. Seven to eight years later, 3,682 participants (74% of survivors) were re-examined. Outcome measures were incidence of overweight/obesity (OW/OB(inc)) and obesity (OB(inc)) (BMI > or = 25 and > or = 30 kg/m(2), respectively), and BMI change by follow-up (DeltaBMI, kg/m(2)). A significant positive dose-response relationship emerged between baseline ASB consumption and all outcome measures, adjusted for baseline BMI and demographic/behavioral characteristics. Consuming >21 ASBs/week (vs. none) was associated with almost-doubled risk of OW/OB (odds ratio (OR) = 1.93, P = 0.007) among 1,250 baseline normal-weight (NW) individuals, and doubled risk of obesity (OR = 2.03, P = 0.0005) among 2,571 individuals with baseline BMIs <30 kg/m(2). Compared with nonusers (+1.01 kg/m(2)), DeltaBMIs were significantly higher for ASB quartiles 2-4: +1.46 (P = 0.003), +1.50 (P = 0.002), and +1.78 kg/m(2) (P < 0.0001), respectively. Overall, adjusted DeltaBMIs were 47% greater among artificial sweetener (AS) users than nonusers (+1.48 kg/m(2) vs. +1.01 kg/m(2), respectively, P < 0.0001). In separate analyses--stratified by gender; ethnicity; baseline weight category, dieting, or diabetes status; or exercise-change category--DeltaBMIs were consistently greater among AS users. These differences, though not significant among exercise increasers, or those with baseline diabetes or BMI >30 kg/m(2) (P = 0.069), were significant in all 13 remaining strata. These findings raise the question whether AS use might be fueling--rather than fighting--our escalating obesity epidemic.

Targeting biomarkers of oxidative-proinflammatory stress may result in improvement of modifiable metabolic syndrome, pre-diabetes and diabetes risk factors and subsequent risk reduction. 64 newly diagnosed antihyperglycemic treatment-naïve prediabetic and type 2 diabetes mellitus (T2DM) patients were randomly assigned using block design to either metformin combined with therapeutic lifestyle changes (TLC) or TLC alone. Body mass index (BMI), waist circumference, blood pressure, fasting plasma glucose (FPG), glycated hemoglobin (HbA1c), fasting lipid profile, plasma oxidative status and tumor necrosis factor (TNF)-α were measured at baseline, after 3 months and after 6 months from baseline. Except for HbA1c, baseline values did not differ significantly between the two groups. The post 3-months relative reductions in BMI (P=0.014) and HbA1c (P=0.037) in metformin combined with TLC intervention were significantly greater than those in TLC alone group. TNFα plasma levels were decreased significantly vs. baseline by metformin combined with TLC intervention (-22.90±46.76%, P=0.01). Conversely, TLC alone basically worsened proinflammatory status (42.40±40.82 %), P<0.001. Metformin with TLC treatment effected a therapeutic decrement of the oxidative stress (-15.44±35.32%, P=0.029 vs. baseline) unlike TLC alone (61.49±122.66%, P=0.01 vs. baseline). Both interventions' effects were sustained in the 6-month follow up periods. In both intervention groups, the relative changes in plasma TNFα were significantly correlated (P<0.01) with systolic blood pressure and the relative changes in oxidative stress were markedly correlated (P<0.05) with total cholesterol.

In assessing poor lumbar surgery outcomes, researchers continue to investigate psychosocial predictors of patient postoperative quality of life. This is the first study of its kind to investigate this relationship in an exclusively minimally invasive patient sample. To determine the association between preoperative mental health and postoperative patient-centered outcomes in patients undergoing minimally invasive lumbar surgery. In 83 adults undergoing single-level minimally invasive lumbar spine surgery, Pearson correlation and partial correlation analyses were conducted between all demographic and clinical baseline variables and Oswestry Disability Index (ODI), Visual Analogue Scale (VAS), and 36-item Short-Form Health Survey Version 2.0 (SF-36v2) scores at 6 to 12 months postoperatively. SF-36v2 mental component summary scores (MCS) were used to assess pre- and postoperative general mental health. Post hoc analysis consisted of Pearson correlations between baseline SF-36v2, ODI, and VAS scores, and an identical set of correlations at outcomes. Preoperative MCS showed no significant association with outcomes VAS, ODI, or physical component summary scores. Baseline disability correlated significantly and more strongly with baseline MCS (P < .001, r = -0.40) than baseline pain levels (VAS back not significant, VAS leg P = .015, r = 0.27). Outcomes disability correlated significantly and more strongly with outcome back and leg pain levels (P < .001, r = 0.60 and 0.66) than outcome MCS (P = .031, r = -0.24). In a patient sample with mental health scores comparable to the population mean, there is no relationship between preoperative general mental health and postoperative patient-centered outcomes. Surgeons should consider the dynamic relationships between patient disability, mental health, and pain levels in assessing quality of life at different time points.

Both hypertension and diabetes in middle-aged individuals have been suggested to be predictive indicators of cognitive decline. However, the association of hypertension, diabetes and their combination with cognitive functioning is still controversial in older people. The purpose of this study was to investigate the association between cognitive decline and hypertension, diabetes, and their combination in 70-year-old people based on a 3-year longitudinal analysis. Four hundred and fifty-four people aged 70 (±1) years who participated in the Japanese longitudinal cohort study of Septuagenarians, Octogenarians and Nonagenarians Investigation with Centenarians (SONIC) were recruited randomly from a general population and were monitored for 3 years. The data, including most of the demographics, cognitive functioning measured by the Montreal Cognitive Assessment Japanese version (MoCA-J), blood pressure, blood chemistry and other medical histories, were collected at baseline and during the follow-up. The prevalence of hypertension noted in the follow-up survey was significantly higher than than noted at baseline. The mean MoCA-J score at follow-up was not significantly different from the score obtained at baseline. However, the participants with diabetes, especially combined with hypertension at baseline, had significantly lower MoCA-J scores than those without lifestyle-related diseases. The combination of hypertension and diabetes was still a significant risk factor for cognitive decline, considering the MoCA-J scores obtained during the follow-up after adjustments at baseline, relative to sex, body mass index, dyslipidemia, smoking, excessive alcohol intake, antihypertensive treatment and education level (β=-0.14; P<0.01). Our findings indicate that diabetes and the combination of hypertension and diabetes are clear risk factors for future cognitive decline in elderly individuals who are 70 years of age.

Treatment for neuropsychiatric symptoms (NPS) in dementia is insufficient. Antipsychotics and acetylcholinesterase inhibitors are used generating symptomatic improvements in behavior and cognition, but few studies have investigated their effect on Alzheimer's disease (AD) biomarkers in cerebrospinal fluid (CSF). This is a secondary analysis based on an earlier clinical trial comparing the treatment effects on NPS. The aim of this study was to examine whether treatment with risperidone and galantamine affect levels of the biomarkers T-Tau, P-Tau, Aβ1-42, and Aβ42/40-ratio in CSF. The secondary aim was to test if baseline levels of these biomarkers are associated with the clinical course of NPS. 83 patients (mean + SD 77.9.6±7.7 years) with dementia and NPS were randomized to galantamine (n = 44) or risperidone (n = 39) treatment. CSF samples were collected at baseline and after 12 weeks. Changes in levels of biomarkers between the two treatment groups did not differ significantly. Low baseline levels of Aβ1 - 42 was significantly associated with reduction of irritability at follow up. Low baseline levels of Aβ1-42, Aβ42/40, and P-Tau were significant correlates of reduction in appetite and eating disorders. CSF Aβ1-42 levels in patients treated with risperidone were significantly decreased at follow up, showing an 8% (40 pg/mL) reduction as compared with baseline (p = 0.03). Our results suggest that risperidone may affect the CSF profile of AD biomarkers indicating more amyloid pathology. Treatment with galantamine did not affect the CSF biomarkers in any direction. The AD CSF biomarkers displayed correlations with specific NPS suggesting potential research questions to be pursued.

Although several micronutrients deficiency were reported to be associated with poor muscle function, however information on sarcopenia patients is still lacking. The aim of this report was to measure some micronutrients blood-based status in sarcopenia patients during both acute illness and recovery. We assessed nutritional status of randomly selected hospitalised patients using anthropometric, haematological and biochemical data at baseline, 6 weeks and at 6 months. Sarcopenia was diagnosed from low muscle mass and low muscle strength using anthropometric measures based on the European Working Group criteria. Micronutrient status was compared between sarcopenia patients and those without sarcopenia over a 6 months period. Forty-four out of 432 patients (10%) were diagnosed with sarcopenia on admission. Patients diagnosed with sarcopenia had lower micronutrients concentrations compared to those patients without sarcopenia however, the results were statistically significant only for baseline serum albumin, red cell folate and plasma zinc (p < 0.05). Lycopene, retinol, red cell folate and zinc were also significantly lower in sarcopenia patients at 6 weeks. Sarcopenia patients readmitted to hospital had poor baseline micronutrient status compared with sarcopenia patients stayed in the community during the 6-months follow up period but differences were not statistically significant. Both baseline serum albumin and plasma zinc were significantly higher in sarcopenia patients who were alive compared with those died at 6 months follow up. Baseline serum albumin and plasma zinc concentrations were lower in patients diagnosed with sarcopenia compared to those without sarcopenia, and also in sarcopenia patients who died compared with those alive at 6 months follow up.

Purpose The purpose of the study was to determine the impact of educational text messages on diabetes self-management activities and outcomes in patients with painful diabetic peripheral neuropathy (pDPN). Methods Patients with pDPN identified from a large integrated health system who agreed to participate were randomized to 6 months of usual care (UC) or UC plus twice-daily diabetes self-management text messages (UC+TxtM). Outcomes included the Pain Numerical Rating Scale, Summary of Diabetes Self-Care Activities (SDSCA), questions on diabetes health beliefs, and glycated hemoglobin (A1C). Changes from baseline were evaluated at 6 months and compared between groups. Results Demographic characteristics were balanced between groups (N = 62; 53% female, mean age = 63 years, 94% type 2 diabetes), as were baseline measures. After 6 months, pain decreased with UC+TxtM from 6.3 to 5.5 and with UC from 6.5 to 6.0, with no difference between groups. UC+TxtM but not UC was associated with significant improvements from baseline on all SDSCA subscales. On diabetes health beliefs, UC+TxtM patients reported significantly increased benefits and reduced barriers and susceptibility relative to UC at 6 months. A1C declined in both groups, but neither change was significant relative to baseline. Conclusions Patients with pDPN who receive twice-daily text messages regarding diabetes management reported reduced pain relative to baseline, although this change was not significant compared with usual care. In addition, text messaging was associated with increased self-management activities and improved diabetes health beliefs and total self-care. These results warrant further investigation.

This study evaluated whether acepromazine or methadone reduced behavioral parameters, overall excitement, and activity associated with midazolam administration to healthy dogs. Dogs received midazolam (M) alone [M: 0.25 mg/kg body weight (BW)] or with methadone (MM) (MM: 0.75 mg/kg BW) or acepromazine (MA) (MA: 0.03 mg/kg BW) or saline (S) solution alone, all intramuscularly. Two blinded observers evaluated behavioral parameters using video recordings 30 min before and after injection of drugs. Accelerometery was used to evaluate “total activity counts” (TAC) at baseline and post-treatment. Post-treatment excitement scores were significantly higher in M and MA compared to baseline, M and MM compared to S, and M compared to MA. Behavioral parameters showed significantly higher proportions of “pacing” post-treatment in all groups receiving midazolam, and “restlessness,” “chewing/licking,” and “sniffing” in M. No significant differences were found for TAC at baseline and post-treatment. Midazolam-induced paradoxical behavioral changes (excitation, panting, pacing, restlessness, licking/chewing, and vocalization) were not prevented by acepromazine or methadone in healthy dogs.

Global population aging will result in increasing rates of cognitive decline and dementia. Thus, effective, low-cost, and low side-effect interventions for the treatment and prevention of cognitive decline are urgently needed. Our study is the first to investigate the effects of Kundalini yoga (KY) training on mild cognitive impairment (MCI). Older participants (≥55 years of age) with MCI were randomized to either a 12-week KY intervention or memory enhancement training (MET; gold-standard, active control). Cognitive (i.e. memory and executive functioning) and mood (i.e. depression, apathy, and resilience) assessments were administered at baseline, 12 weeks and 24 weeks. At baseline, 81 participants had no significant baseline group differences in clinical or demographic characteristics. At 12 weeks and 24 weeks, both KY and MET groups showed significant improvement in memory; however, only KY showed significant improvement in executive functioning. Only the KY group showed significant improvement in depressive symptoms and resilience at week 12. KY group showed short- and long-term improvements in executive functioning as compared to MET, and broader effects on depressed mood and resilience. This observation should be confirmed in future clinical trials of yoga intervention for treatment and prevention of cognitive decline (NCT01983930).

Human pregnancies complicated by placental dysfunction may be characterized by a high hyperoxic Blood oxygen level-dependent (BOLD) MRI response. The pathophysiology behind this phenomenon remains to be established. The aim of this study was to evaluate whether it is associated with altered placental baseline conditions, including a lower oxygenation and altered tissue morphology, as estimated by the placental transverse relaxation time (T2*). We included 49 normal pregnancies (controls) and 13 pregnancies complicated by placental dysfunction (cases), defined by a birth weight < 10th percentile in combination with placental pathological signs of vascular malperfusion. During maternal oxygen inhalation, we measured the relative ΔBOLD response ((hyperoxic BOLD - baseline BOLD)/baseline BOLD) from a dynamic single-echo gradient-recalled echo (GRE) MRI sequence and the absolute ΔT2* (hyperoxic T2*- baseline T2*) from breath-hold multi-echo GRE sequences. In the control group, the relative ΔBOLD response increased during gestation from 5% in gestational week 20 to 20% in week 40. In the case group, the relative ΔBOLD response was significantly higher (mean Z-score 4.94; 95% CI 2.41, 7.47). The absolute ΔT2*, however, did not differ between controls and cases (p = 0.37), whereas the baseline T2* was lower among cases (mean Z-score -3.13; 95% CI -3.94, -2.32). Furthermore, we demonstrated a strong negative linear correlation between the Log 10 ΔBOLD response and the baseline T2* (r = -0.88, p < 0.0001). The high hyperoxic ΔBOLD response demonstrated in pregnancies complicated by placental dysfunction may simply reflect altered baseline conditions, as the absolute increase in placental oxygenation (ΔT2*) does not differ between groups.

Antireflux therapy may lead to recovery of impaired mucosal integrity in gastro-esophageal reflux disease (GERD) patients as reflected by an increase in baseline impedance. The study objective was to evaluate the effect of endoscopic fundoplication and proton pump inhibitor (PPI) PPI therapy on baseline impedance and heartburn severity in GERD patients. Forty-seven GERD patients randomized to endoscopic fundoplication (n = 32) or PPI therapy (n = 15), and 29 healthy controls were included. Before randomization and 6 months after treatment, baseline impedance was obtained during 24-h pH-impedance monitoring. Heartburn severity was evaluated using the GERD-HRQL questionnaire. Before treatment, baseline impedance in GERD patients was lower than in healthy controls (p < 0.001). Antireflux therapy increased baseline impedance (from 1498 [IQR 951-2472] to 2393 [IQR 1353-3027] Ω, p = 0.001), however it only led to a partial recovery when compared to healthy controls (2393 [IQR 1353-3027] vs 2983 [2335-3810] Ω, p < 0.01). The effect of both treatment options was not significantly different (p = 0.13) despite the increased number of non-acid reflux events in the PPI group. No correlation was found between baseline impedance and GERD symptoms before or after treatment. Reduction in acid reflux by endoscopic fundoplication or PPI therapy leads to an increase in baseline impedance in GERD patients, likely to reflect recovery of mucosal integrity. The impact of non-acid reflux events on esophageal mucosal integrity may be limited as no difference in the increase in baseline impedance was observed after both treatment options. The lack of association between impedance baseline and heartburn severity indicates that other factors may contribute to heartburn perception in GERD. © 2014 John Wiley & Sons Ltd.

Comparisons between men and women of time course responses of strength, delayed-onset muscle soreness (DOMS), and muscle swelling after a resistance training session are still controversial. Therefore, this study examined gender differences in strength loss, muscle thickness (MT), and DOMS between young men and women. Thirty apparently healthy, untrained volunteers (14 women and 16 men) participated in the study protocol. The resistance exercise session consisted of 8 sets at 10 repetition maximum load of the elbow flexor muscles of their dominant arm. Maximum isokinetic peak torque (PT), MT, and DOMS were recorded at baseline (TB), immediately after exercise (T0), and at 1 (T1), 2 (T2), 3 (T3), and 4 (T4) days after exercise. Baseline strength was expressed as 100%. There were no significant differences between the sexes for relative PT loss immediately after exercise (T0 = 74.31 ± 8.26% for men and 76.00 ± 6.31% for women). Also, PT was still significantly less than baseline from T1 to T4 for both genders. In contrast, recovery from PT was longer in women when compared with that in men. Muscle thickness responded similarly to PT in both genders. However, there was no significant difference between genders for DOMS at any time point. The time point that showed the greatest degree of mean soreness was T2 (4.94 ± 2.38 mm for men and 4.45 ± 2.07 mm for women). Our data suggest that after resistance exercise, women and men experience similar immediate strength loss; however they have dissimilar strength recovery across 4 days of recovery. Likewise, both genders experience a different time course of MT response after a traditional resistance exercise protocol. In contrast, men and women develop and dissipate muscle soreness in a similar manner.

We wanted to determine whether basal insulin requirements change when patients transition from insulin glargine U-100 (Gla-100) to insulin glargine U-300 (Gla-300) or insulin degludec. This study involved subjects seen in the University of Colorado Health Endocrine Clinic who were transitioned from Gla-100 to either Gla-300 ( n = 95) or insulin degludec ( n = 39). The primary outcome was the difference between baseline Gla-100 dose and dose of Gla-300 or insulin degludec prescribed after first follow-up visit within 1-12 months. Secondary outcomes included changes in glycemic control and empiric dose conversion from Gla-100 to Gla-300 or insulin degludec on the day of transition. Wilcoxon rank sum tests evaluated changes in insulin doses, and paired t tests assessed changes in glycemic control using GraphPad statistical software. Median daily basal insulin dose increased for individuals transitioned from Gla-100 to Gla-300 from 30 [19-60 interquartile range (IQR)] units at baseline to 34.5 (19-70 IQR) units after follow up ( p = 0.01). For patients transitioned to insulin degludec, dose changes from baseline to follow up were not significantly different ( p = 0.56). At the time of transition, the prescribed dose of Gla-300 or insulin degludec did not significantly differ from the previous dose of Gla-100 ( p = 0.73 and 0.28, respectively), indicating that empiric dose adjustments were not routinely prescribed. Patients who transitioned from Gla-100 to Gla-300 had increased basal insulin requirements between visits, while basal insulin requirements for those transitioned from Gla-100 to insulin degludec were not significantly different.

We assessed the relation between baseline electrocardiographic ischemia grades and initial myocardial area at risk (AR) and final infarct size (IS) in 49 patients who had undergone (99m)Tc sestamibi single-photon emission computed tomography before and 6 +/- 1 days after thrombolysis. Patients were classed as having grade III ischemia (ST segment elevation with terminal QRS distortion, n = 19) or grade II ischemia (ST elevation but no terminal QRS distortion, n = 30). We compared AR and IS by baseline ischemia grade and treatment (adenosine vs. placebo) and assessed relations of infarction index (IS/AR ratio x100) to time to thrombolysis, baseline ischemia grade, and adenosine therapy. Time to thrombolysis was similar for grade II and grade III. For placebo- treated patients, the median AR did not differ significantly between grade II (38%) and grade III patients (46%, p = 0.47), nor did median IS (16 vs. 40%, p = 0.096), but the median infarction index was 66 vs. 90% (p = 0.006). For adenosine-treated patients, median AR (21 vs. 26%, p = 0.44), median IS (5 vs. 17%, p = 0.15), and their ratio (31 vs. 67%, p = 0.23) did not differ significantly between grade II and grade III patients. The infarction index independently related to grade III ischemia (p = 0.0121) and adenosine therapy (p = 0.045). Infarct size related to baseline ischemia grade and was reduced by adenosine treatment. Necrosis progressed slowlier with baseline grade II versus III ischemia, which could offer more time for myocardial salvage with reperfusion. Copyright 2002 S. Karger AG, Basel

Cognitive impairment is very common in late-life depression, principally affecting executive skills and information processing speed. The aim of the study was to examine the effect of antidepressant treatment on cognitive performances over a 10-year period. The community-based cohort included 7381 participants aged 65 years and above. Five cognitive domains (verbal fluency, psychomotor speed, executive function, visuospatial skills and global cognition) were assessed up to five times over 10 years of follow-up. Treatment groups included participants under a specific antidepressant class at both baseline and the first follow-up and their follow-up cognitive data were considered until the last consecutive follow-up with a report of antidepressant use of the same class. Linear mixed models were used to compare baseline cognitive performance and cognitive decline over time according to antidepressant treatment. The models were adjusted for multiple confounders including residual depressive symptoms assessed by the Center for Epidemiologic Studies-Depression scale. At baseline, 4.0% of participants were taking antidepressants. Compared to non-users, tricyclic antidepressant users had lower baseline performances in verbal fluency, visual memory and psychomotor speed, and selective serotonin reuptake inhibitor users in verbal fluency and psychomotor speed. For the two other cognitive abilities, executive function and global cognition, no significant differences were found at baseline irrespective of the antidepressant class. Regarding changes over time, no significant differences were observed in comparison with non-users whatever the cognitive domain, except for a slight additional improvement over the follow-up in verbal fluency skills for tricyclic antidepressant users. In this large elderly general population cohort, we found no evidence for an association between antidepressant use and post-treatment cognitive decline over 10 years of follow-up in various cognitive domains.

The 6 minute walk test has been recently chosen as the primary outcome measure in international multicenter clinical trials in Duchenne muscular dystrophy ambulant patients. The aim of the study was to assess the spectrum of changes at 3 years in the individual measures, their correlation with steroid treatment, age and 6 minute walk test values at baseline. Ninety-six patients from 11 centers were assessed at baseline and 12, 24 and 36 months after baseline using the 6 minute walk test and the North Star Ambulatory Assessment. Three boys (3%) lost the ability to perform the 6 minute walk test within 12 months, another 13 between 12 and 24 months (14%) and 11 between 24 and 36 months (12%). The 6 minute walk test showed an average overall decline of −15.8 (SD 77.3) m at 12 months, of −58.9 (SD 125.7) m at 24 months and −104.22 (SD 146.2) m at 36 months. The changes were significantly different in the two baseline age groups and according to the baseline 6 minute walk test values (below and above 350 m) (p<0.001). The changes were also significantly different according to steroid treatment (p = 0.01). Similar findings were found for the North Star Ambulatory Assessment. These are the first 36 month longitudinal data using the 6 minute walk test and North Star Ambulatory Assessment in Duchenne muscular dystrophy. Our findings will help not only to have a better idea of the progression of the disorder but also provide reference data that can be used to compare with the results of the long term extension studies that are becoming available.

Objectives To determine whether heterogeneity in interleukin-6 (IL-6), IL-6 receptor and other components of the IL-6 signalling pathway/network, at the gene, transcript and protein levels, correlate with disease activity in patients with rheumatoid arthritis (RA) and with clinical response to tocilizumab. Design Biomarker samples and clinical data for five phase 3 trials of tocilizumab were analysed using serum (3751 samples), genotype (927 samples) and transcript (217 samples) analyses. Linear regression was then used to assess the association between these markers and either baseline disease activity or treatment response. Results Higher baseline serum IL-6 levels were significantly associated (p<0.0001) with higher baseline DAS28, erythrocyte sedimentation rate, C reactive protein and Health Assessment Questionnaire in patients whose responses to disease-modifying antirheumatic drugs (DMARD-IR) and to antitumour necrosis factor (aTNF-IR) were inadequate and patients who were naive/responders to methotrexate (MTX). Higher baseline serum IL-6 levels were also significantly associated with better clinical response to tocilizumab (versus placebo) measured by cDAS28 in the pooled DMARD-IR (p<0.0001) and MTX-naive populations (p=0.04). However, the association with treatment response was weak. A threefold difference in baseline IL-6 level corresponded to only a 0.17-unit difference in DAS28 at week 16. IL-6 pathway single nucleotide polymorphisms and RNA levels also were not strongly associated with treatment response. Conclusions Our analyses illustrate that the biological activity of a disease-associated molecular pathway may impact the benefit of a therapy targeting that pathway. However, the variation in pathway activity, as measured in blood, may not be a strong predictor. These data suggest that the major contribution to variability in clinical responsiveness to therapeutics in RA remains unknown. PMID:23959753

The aim of this study was to investigate the efficacy of nootropics (piracetam, aniracetam, nimodopine and dihydroergicristine) versus acetylcholinesterase inhibitors (AChE-Is) (tacrine and donepezil) in the treatment of Alzheimer's disease. This is a retrospective study of 510 patients with Alzheimer's disease. To determine clinical efficacy of treatment, we used the mean change over time in scores for the following tests: the Mini-Mental State Examination (MMSE); the Cambridge Cognitive Examination for the Elderly; and the Functional Rating Scale for Symptoms of Dementia. In all patients and in patients with severe Alzheimer's disease (baseline MMSE < 11), no significant differences were seen in the neuropsychological test scores between the two treatment groups. In patients with moderate dementia (baseline MMSE between 11 and 20), however, there was a significantly greater deterioration, as shown on the CAMCOG scale, after 12 months' treatment for patients receiving AChE-Is compared with those receiving nootropics (-4.38 for AChE-Is group versus 1.48 for nootropics group). For patients with mild dementia (baseline MMSE score between 21 and 26), there was a significantly greater deterioration on the MMSE scale for each time-point in the nootropics group compared with the AChE-Is group. In conclusion, we did not find any strong evidence that a difference in efficacy exists between AChE-Is and nootropics in the treatment of Alzheimer's disease.

Objective To clarify the impact of hearing aids on mental health, social engagement, cognitive function, and physical health outcomes in older adults with hearing impairment. Design We assessed hearing handicap (Hearing Handicap Inventory for the Elderly; HHIE-S), cognition (Mini Mental State Exam, Trail Making, Auditory Verbal Learning, Digit-Symbol Substitution, Verbal Fluency, incidence of cognitive impairment), physical health (SF-12 physical component, basic and instrumental activities of daily living, mortality), social engagement (hours per week spent in solitary activities) and mental health (SF-12 mental component) at baseline, 5 years prior to baseline, and 5 and 11 years after baseline. Study sample Community-dwelling older adults with hearing impairment (N=666) from the Epidemiology of Hearing Loss Study cohort. Results There were no significant differences between hearing aid users and non-users in cognitive, social engagement or mental health outcomes at any time point. Aided HHIE-S was significantly better than unaided HHIE-S. At 11 years hearing aid users had significantly better SF-12 physical health scores (46.2 versus 41.2; p=0.03). There was no difference in incidence of cognitive impairment or mortality. Conclusion There was no evidence that hearing aids promote cognitive function, mental health, or social engagement. Hearing aids may reduce hearing handicap and promote better physical health. PMID:26140300

To demonstrate the feasibility of a skills-based substance abuse prevention counseling program in a community setting for adults who sustained traumatic brain injury. Convenience sample of 117 participants (mean age=35 years) with preinjury history of alcohol or other drug use. Intervention group participants (n=36) from 3 vocational rehabilitation programs; a no-intervention comparison group (n=81) from an outpatient rehabilitation service. 12 individual counseling sessions featuring skills-based intervention. Changes in self-reported alcohol and other drug use, coping skillfulness, affect, and employment status from baseline to 9 months postintervention. Significant differences were noted at baseline for the intervention and comparison groups on ethnicity, time postinjury, marital status, and employment (P<.05). At the 9-month follow-up, the intervention group participants achieved a statistically significant decrease in alcohol and drug use (P<.05), increase in coping skillfulness (P<.01), and increased likelihood of maintaining employment (P<.01) relative to the comparison group. Controlling for baseline-adjusted means for the intervention and comparison groups, a statistically significant group difference in adjusted change was noted; the intervention group participants reported lower negative affect at the 9-month follow-up assessment (P<.05). A skills-based intervention provides a promising approach to promoting abstinence from all substances and increasing readiness for employment for adults with traumatic brain injuries in outpatient settings.

This study investigates the effect of exposure to a mobile phone-like radiofrequency (RF) electromagnetic field on people with atopic dermatitis (AD). Fifteen subjects with AD were recruited and matched with 15 controls without AD. The subjects were exposed for 30 min to an RF field at 1 W/kg via an indoor base station antenna attached to a 900 MHz GSM mobile phone. Blood samples for ELISA analysis of the concentration of substance P (SP), tumor necrosis factor receptor 1 (TNF R1), and brain derived neurotrophic factor (BDNF) in serum were drawn before and after the provocation (exposure/sham). Baseline heart rate and heart rate variability, local blood flow, and electrodermal activity were also recorded. No significant differences between the subject groups were found for baseline neurophysiological data. The cases displayed a serum concentration of TNF R1 significantly higher than the control subjects and a significantly lower serum concentration of BDNF in the baseline condition. For SP there was no difference between groups. However, no effects related to RF exposure condition were encountered for any of the measured substances. As to symptoms, a possible correlation with exposure could not be evaluated, due to too few symptom reports. The result of the study does not support the hypothesis of an effect of mobile phone-like RF exposure on serum levels of SP, TNF R1, and BDNF in persons with AD.

Caring for a person with a mental illness can have adverse effects on caregivers; however, little is known about how best to help such caregivers. The aim of the present study was to examine the efficacy of a cognitive behaviour therapy-guided self-help manual in increasing resilience in caregivers of individuals with depression, in comparison to caregivers who receive routine support only. A randomized, controlled trial was conducted, following CONSORT guidelines, with 54 caregivers allocated to parallel intervention (self-help manual) (n = 27) or control (standard support) (n = 27) groups. Resilience was assessed at baseline, post-test (week 8), and follow up (week 12). Intention-to-treat analyses were undertaken. Repeated-measures ANOVA indicated a significant difference in resilience scores between the three time points, showing a large effect. Pairwise comparisons between intervention and control groups indicated resilience to be significantly different between baseline and post-test, and between baseline and follow up, but not between post-test and follow up. Overall, the intervention group showed a slightly greater increase in resilience over time than the control group; however, the time-group interaction was not significant. Guided self-help is helpful in improving caregivers' resilience and could be used as an adjunct to the limited support provided to carers by mental health nurses and other clinicians. © 2016 Australian College of Mental Health Nurses Inc.

Estimated glomerular filtration rates (eGFRs) at baseline are useful to determine the severity of renal function and to predict cardiac events. However, no studies aimed to demonstrate significance of eGFRs measured during follow-up and usefulness of combination with nuclear cardiology for prediction of cardiac death in patients with coronary artery disease (CAD). We retrospectively investigated 1739 patients with known/suspected CAD who underwent myocardial perfusion single photon emission computed tomography (SPECT), who had eGFRs measured at baseline and after one year and who underwent a three-year follow-up. The SPECT images were analyzed with the visual scoring model to estimate summed defect scores. Reduction in eGFRs (ΔeGFR) was defined as the difference between eGFRs measured after one year and at baseline. The endpoint of the follow-up was cardiac deaths within three years after the SPECT, which were identified with medical records or responses to posted questionnaires. Cardiac death was observed in 54 of 1739 patients during the follow-up period (45.6±9.1 months). The multivariate Cox regression analysis showed baseline eGFRs, ΔeGFR, and summed stress scores to be significant independent variables for prediction of cardiac death. The area under receiver operating characteristic curves for detection of cardiac death was 0.677 for the baseline eGFR and 0.802 for the follow-up eGFR. Sensitivity of detection of cardiac death was significantly higher in the follow-up eGFR than in the baseline eGFR (p=0.0002). Combination of the best cut-off values, i.e. 9 for the summed stress scores and 10 for the ΔeGFR, which were suggested by receiver operating characteristic analysis, was useful for risk stratification of cardiac death both in patients with and without chronic kidney disease. Baseline and follow-up eGFRs as well as nuclear variables are useful to predict cardiac death in patients with known/suspected CAD. Copyright © 2015 Japanese College of Cardiology.

Bariatric surgery improves sexual function in obese individuals, although the extent to which sexual satisfaction is improved following surgery is unknown. The aims of this study were 1) to describe sexual satisfaction in severely/morbidly obese men and women candidates for bariatric surgery; 2) to assess the effects of bariatric surgery on sexual satisfaction at 12-months follow-up; and 3) to assess whether weight changes at follow-up following bariatric surgery are associated with changes in sexual satisfaction. We conducted a prospective observational study from February 2011 to June 2014. A total of 44 patients with severe/morbid obesity participated in the study. Sexual satisfaction was assessed (at baseline and 12-months follow-up) through the Index of Sexual Satisfaction (ISS) questionnaire. Of 44 patients who completed the ISS at baseline (mean age 40.3 [SD=9.4] years and BMI 46.9 [SD=6.2] kg/m 2 ), 17 were lost to follow-up. The baseline ISS total scores were 32.0 (SD=20.1) in women and 24.4 (SD=16.0) in men (P>0.05). The proportion of sexually satisfied men and women at baseline was 62.5% and 46.4%, respectively (P=0.360). At follow-up, sexual satisfaction improved significantly in women (average difference 13.7 units; P=0.032) but not in men (average difference 3.6 units; P=0.717). The percentage of women with sexual satisfaction problems was reduced by 33% at follow-up (P=0.038). A relatively large percentage of severely/morbidly obese women and men present clinically significant sexual satisfaction problems before undergoing bariatric surgery. Sexual satisfaction improves significantly 12 months following bariatric surgery, particularly in women. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

The HARMONY study was a randomized, controlled trial examining the efficacy of an 8-week mindfulness-based stress reduction (MBSR) program for blood pressure (BP) lowering among unmedicated stage 1 hypertensive participants. Participants diagnosed with stage 1 hypertension based on ambulatory BP were randomized to either immediate treatment of MBSR for 8 weeks or wait-list control. Primary outcome analysis evaluated whether change in awake and 24-hour ambulatory BP from baseline to week 12 was significantly different between the 2 groups. A within-group before and after MBSR analysis was also performed. The study enrolled 101 adults (38% male) with baseline average 24-hour ambulatory BP of 135±7.9/82±5.8mm Hg and daytime ambulatory BP of 140±7.7/87±6.3 mmHg. At week 12, the change from baseline in 24-hour ambulatory BP was 0.4±6.7/0.0±4.9mm Hg for the immediate intervention and 0.4±7.8/-0.4±4.6mm Hg for the wait-list control. There were no significant differences between intervention and wait-list control for all ambulatory BP parameters. The secondary within-group analysis found a small reduction in BP after MBSR compared with baseline, a finding limited to female subjects in a sex analysis. MBSR did not lower ambulatory BP by a statistically or clinically significant amount in untreated, stage 1 hypertensive patients when compared with a wait-list control group. It leaves untested whether MBSR might be useful for lowering BP by improving adherence in treated hypertensive participants. NCT00825526.

To describe longitudinal changes in corneal curvature (CC) and axial length (AL) over 14 years, and to explore the relationship between AL and CC, and the axial length/corneal radius (AL/CR) ratio. In total 469, 6 to <12-year-old, children were enrolled in COMET. Measurements of refractive error, CC (D), CR (mm), and ocular component dimensions including AL were gathered annually. Linear mixed models were used to evaluate longitudinal changes adjusting for covariates (gender, ethnicity, lens type, baseline age and baseline refraction). The Pearson correlation coefficient between AL and CC was computed at each visit. There was a slight but significant (p<0.0001) flattening in CC over 14 years. At all visits females had significantly steeper CC than males (overall difference=0.53 D, p<0.0001). Caucasians had the steepest CC, and Hispanics the flattest (p=0.001). The correlation between AL and CC was -0.70 (p<0.0001) at baseline (mean age=9.3 years) and decreased to -0.53 (p<0.0001) at the 14-year visit (mean age=24.1 years). The average AL/CR ratio was 3.15 at baseline and increased to 3.31 at the 14-year visit. The correlation between the magnitude of myopia and AL/CR ratio was significantly higher (p<0.0001) at each visit than the correlation between myopia and AL alone. Differences in average corneal curvature by age, gender, and ethnicity observed in early childhood remain consistent as myopia progresses and stabilizes. This study also demonstrates increases in the AL/CR ratio as myopia progresses and then stabilizes, supporting observations from previous cross-sectional data.

Background: There is limited evidence about the distinguished effect of 3D oral health education videos over conventional 2 dimensional projections in improving oral health knowledge. This randomized controlled trial was done to test the effect of 3 dimensional oral health educational videos among first year dental students. Materials and Methods: 80 first year dental students were enrolled and divided into two groups (test and control). In the test group, 3D animation and in the control group, regular 2D video projections pertaining to periodontal anatomy, etiology, presenting conditions, preventive measures and treatment of periodontal problems were shown. Effect of 3D animation was evaluated by using a questionnaire consisting of 10 multiple choice questions given to all participants at baseline, immediately after and 1month after the intervention. Clinical parameters like Plaque Index (PI), Gingival Bleeding Index (GBI), and Oral Hygiene Index Simplified (OHI-S) were measured at baseline and 1 month follow up. Results: A significant difference in the post intervention knowledge scores was found between the groups as assessed by unpaired t-test (p<0.001) at baseline, immediate and after 1 month. At baseline, all the clinical parameters in the both the groups were similar and showed a significant reduction (p<0.001)p after 1 month, whereas no significant difference was noticed post intervention between the groups. Conclusion: 3D animation videos are more effective over 2D videos in periodontal disease education and knowledge recall. The application of 3D animation results also demonstrate a better visual comprehension for students and greater health care outcomes. PMID:26759805

Malocclusion is a common disease of oral and maxillofacial region. The study was aimed to investigate levels changes of periodontal pathogens in malocclusion patients before, during and after orthodontic treatments, and to confirm the difference between adults and children. One hundred and eight malocclusion patients (46 adults and 62 children at the school-age) were randomly selected and received orthodontic treatment with fixed orthodontic appliances. Subgingival plaques were Porphyromonas gingivalis (P.gingivalis), Fusobacterium nucleatum (F. nucleatum), Prevotella intermedia (P. intermedia) and Tannerella forsythensis (T. forsythensis) collected from the observed regions before and after treatment. Clinical indexes, including plaque index (PLI), gingival index (GI), sulcus bleeding index (SBI), probing depth (PD) and attachment loss (AL) of observed teeth were examined. The detection rates of P.gingivalis, F. nucleatum, P. intermedia and T. forsythensis increased from baseline to the third month without significant difference, and then returned to pretreatment levels 12 month after applying fixed orthodontic appliances. Adults' percentage contents of P.gingivalis, F. nucleatum, P. intermedia and T. forsythensis were significantly higher than those of children at baseline and the first month, but not obvious at the third month. PLI and SBI were increased from baseline to the first and to the third month both in adults and children groups. Besides, PD were increased from baseline to first month, followed by a downward trend in the third month; however, all patients were failed to detect with AL. Periodontal and microbiological statuses of malocclusion patients may be influenced by fixed orthodontic appliances in both adults and children, more significant in children than in adults. Some microbiological indexes have synchronous trend with the clinical indexes. Long-term efficacy of fixed orthodontic appliances for malocclusion should be confirmed by future researches.

Here, we investigated 2-(5-fluoro-pentyl)-2-methyl-malonic acid ( 18F-ML-10) positron emission tomography (PET) imaging of apoptosis posttherapy to determine optimal timing for predicting chemotherapy response in a mouse head/neck xenograft cancer model. BALB/c nude mice (4-8 weeks old) were implanted with UM-SCC-22B tumors. The treatment group received 2 doses of doxorubicin (10 mg/kg, days 0, 2). Small animal 18F-ML-10 PET/computed tomography was performed before and on days 1, 3, and 7 postchemotherapy. Using regions of interest around tumors, 18F-ML-10 uptake change was measured as %ID/g and uptake relative to liver. Terminal Uridine Nick-End Labeling (TUNEL) immunohistochemistry assay was performed using tumor samplesmore » of baseline and on days 1, 3, and 7 posttreatment. As a result, treated mice demonstrated increased 18F-ML-10 uptake compared to baseline and controls, and 10 of 13 mice showed tumor volume decreases. All control mice showed tumor volume increases. Tumor-to-liver (T/L) ratios from the control group mice did not show significant change from baseline ( P > .05); however, T/L ratios of the treatment group showed significant 18F-ML-10 uptake differences from baseline compared to days 3 and 7 posttreatment ( P < .05), but no significant difference at 1 day posttreatment. In conclusion, 2-(5-Fluoro-pentyl)-2-methyl-malonic acid PET imaging has the potential for early assessment of treatment-induced apoptosis. Timing and image analysis strategies may require optimization, depending on the type of tumor and cancer treatment.« less

The long-term protective effect of stronger back muscles on the spine was determined in 50 healthy white postmenopausal women, aged 58-75 years, 8 years after they had completed a 2 year randomized, controlled trial. Twenty-seven subjects had performed progressive, resistive back-strengthening exercises for 2 years and 23 had served as controls. Bone mineral density, spine radiographs, back extensor strength, biochemical marker values, and level of physical activity were obtained for all subjects at baseline, 2 years, and 10 years. Mean back extensor strength (BES) in the back-exercise (BE) group was 39.4 kg at baseline, 66.8 kg at 2 years (after 2 years of prescribed exercises), and 32.9 kg at 10 years (8 years after cessation of the prescribed exercises). Mean BES in the control (C) group was 36.9 kg at baseline, 49.0 kg at 2 years, and 26.9 kg at 10 years. The difference between the two groups was still statistically significant at 10 year follow-up (p = 0.001). The difference in bone mineral density, which was not significant between the two groups at baseline and 2 year follow-up, was significant at 10 year follow-up (p = 0.0004). The incidence of vertebral compression fracture was 14 fractures in 322 vertebral bodies examined (4.3%) in the C group and 6 fractures in 378 vertebral bodies examined (1.6%) in the BE group (chi-square test, p = 0.0290). The relative risk for compression fracture was 2.7 times greater in the C group than in the BE group. To our knowledge, this is the first study reported in the literature demonstrating the long-term effect of strong back muscles on the reduction of vertebral fractures in estrogen-deficient women.

Purpose: Because of the trade-off between the potentially negative quality-of-life (QoL) effects and uncertain favorable survival effect of neoadjuvant chemoradiotherapy (CRT) in patients with resectable esophageal cancer, we assessed heath-related QoL (HRQoL) for up to 1 year postoperatively in these patients treated with preoperative CRT with a non-platinum-based outpatient regimen followed by esophagectomy. Methods and Materials: Patients undergoing neoadjuvant paclitaxel and carboplatin therapy concurrent with radiotherapy followed by surgery completed standardized HRQoL questionnaires before and after CRT and at regular times up to 1 year postoperatively. We analyzed differences in generic Qol core questionnaire [QLQ-C30] and condition-specific (esophageal site-specific [OES-18])more » HRQoL scores over time by using a linear mixed-effects model. Results: Mean scores of most HRQoL scales deteriorated significantly during neoadjuvant CRT. The largest deterioration was observed for physical and role-functioning scales. All except two symptom scores worsened significantly. Postoperatively, most mean HRQoL scores improved until recovery to baseline level. Speed of improvement varied. Average taste score returned to baseline 3 months postoperatively, whereas it took 1 year for the average role-functioning score to restore. The emotional-functioning score showed a different pattern; it was worst at baseline and increased over time during CRT and postoperatively. Dysphagia and pain scores worsened considerably during CRT, restored to baseline 3 months postoperatively, and were even significantly better 1 year postoperatively. Conclusions: Preoperative CRT with paclitaxel and carboplatin for patients with resectable esophageal cancer had a considerable temporary negative effect on most aspects of HRQoL. Nonetheless, all HRQoL scores were restored or even improved 1 year postoperatively.« less

Here, we investigated 2-(5-fluoro-pentyl)-2-methyl-malonic acid ( 18F-ML-10) positron emission tomography (PET) imaging of apoptosis posttherapy to determine optimal timing for predicting chemotherapy response in a mouse head/neck xenograft cancer model. BALB/c nude mice (4-8 weeks old) were implanted with UM-SCC-22B tumors. The treatment group received 2 doses of doxorubicin (10 mg/kg, days 0, 2). Small animal 18F-ML-10 PET/computed tomography was performed before and on days 1, 3, and 7 postchemotherapy. Using regions of interest around tumors, 18F-ML-10 uptake change was measured as %ID/g and uptake relative to liver. Terminal Uridine Nick-End Labeling (TUNEL) immunohistochemistry assay was performed using tumor samplesmore » of baseline and on days 1, 3, and 7 posttreatment. As a result, treated mice demonstrated increased 18F-ML-10 uptake compared to baseline and controls, and 10 of 13 mice showed tumor volume decreases. All control mice showed tumor volume increases. Tumor-to-liver (T/L) ratios from the control group mice did not show significant change from baseline ( P > .05); however, T/L ratios of the treatment group showed significant 18F-ML-10 uptake differences from baseline compared to days 3 and 7 posttreatment ( P < .05), but no significant difference at 1 day posttreatment. In conclusion, 2-(5-Fluoro-pentyl)-2-methyl-malonic acid PET imaging has the potential for early assessment of treatment-induced apoptosis. Timing and image analysis strategies may require optimization, depending on the type of tumor and cancer treatment.« less

Azilsartan is a novel angiotensin receptor blocker being developed for hypertension treatment. This 16-week, multicenter, randomized, double-blind study compared the efficacy and safety of azilsartan (20-40 mg once daily by forced titration) and its ability to provide 24-h blood pressure (BP) control, with that of candesartan cilexetil (candesartan; 8-12 mg once daily by forced titration) in 622 Japanese patients with grade I-II essential hypertension. Efficacy was evaluated by clinic-measured sitting BP, and by ambulatory BP monitoring (ABPM) at week 14. Participants (mean age: 57 years, 61% males) had a mean baseline sitting BP of 159.8/100.4 mm Hg. The mean change from baseline in sitting diastolic BP at week 16 (primary endpoint) was -12.4 mm Hg in the azilsartan group and -9.8 mm Hg in the candesartan group, demonstrating a statistically significant greater reduction with azilsartan vs. candesartan (difference: -2.6 mm Hg, 95% confidence interval (CI): -4.08 to -1.22 mm Hg, P=0.0003). The week 16 (secondary endpoint) mean change from baseline in sitting systolic BP was -21.8 mm Hg and -17.5 mm Hg, respectively, a significant decrease with azilsartan vs. candesartan (difference: -4.4 mm Hg, 95% CI: -6.53 to -2.20 mm Hg, P<0.0001). On ABPM, the week 14 mean changes from baseline in diastolic and systolic BP were also significantly greater with azilsartan over a 24-h period, and during the daytime, night-time and early morning. Safety and tolerability were similar among the two groups. These data demonstrate that once-daily azilsartan provides a more potent 24-h sustained antihypertensive effect than that of candesartan but with equivalent safety.

This study was designed to compare the effects of simvastatin versus a combination of simvastatin with vitamin C or E on serum lipid profile, particularly, high-density lipoprotein (HDL)-cholesterol (C) level, in patients with a low HDL-C level. Fifty-nine women and 49 men, who had a baseline HDL-C level equal to or lower than 40 mg/dl were randomized to one of the following study treatment groups: Group S (n=39) simvastatin 20 mg/day, Group S+C (n=33) simvastatin 20 mg/day + vitamin C 500 mg/day, and Group S+E (n=36) simvastatin 20 mg/day + vitamin E 400 IU/day. The groups' lipid profiles were obtained at baseline, 3rd and 6th months. Comparing with baseline values, total-C and low-density cholesterol (LDL-C) values significantly reduced (p<0.001) and HDL-C values significantly increased (Group S--33.9+/-3.9 mg/dl vs. 39.8+/-6.9 mg/dl, Group S+C--34.2+/-3.5 mg/dl vs. 38.1+/-6.1 mg/dl, Group S+E--33.1+/-3.6 mg/dl vs. 34.8+/-5.9 mg/dl, p<0.001) on therapy within the groups; however, there were no significant differences among the groups with regards to these parameters. The HDL-C levels increased from baseline by 14.0%, 11.7% and 10.2% in Group S, S+C, and S+E, respectively (p>0.05). A combination of simvastatin with antioxidant vitamins does not offer any beneficial effect over simvastatin alone. Particularly vitamin E seems to blunt the simvastatin induced HDL-C increase.

The objective of this clinical trial was to assess the safety and efficacy of radiofrequency (RF) tissue ablation of the inferior turbinates in the treatment of nasal obstruction using an RF energy delivery system with a thermocouple feedback electrode. A prospective, nonrandomized study of 11 patients (mean age, 47+/-12 y) with chronic nasal obstruction was conducted. Using patient-based visual analogue scales (VAS), symptom parameters were assessed. These included degree of nasal obstruction, frequency of nasal obstruction, and pain. Physician assessment of nasal obstruction was also collected by the principal investigator. Follow-up was conducted at 24 hours, 1 week, 4 weeks, 8 weeks, and 1 year. ANOVA was carried out to determine statistically significant differences in the data. Data were fit to a regression model, and confidence intervals were determined from a 95% confidence level. In patient-assessed degree of nasal obstruction, statistical significance was seen among baseline and 4 weeks, 8 weeks, and 1 year (P<.001, P<.0001, and P<.0008, respectively). There was no difference between 8 weeks and 1 year (P<.15). The data appeared to follow an exponential decay to a constant value. The pretreatment baseline average degree of obstruction was 7.5+/-0.5 on a scale of 0 to 10. The degree of obstruction after 8 weeks was 2.7+/-0.6. The time constant for this change was 21 days to reach 90% of the final value. At 1 year, degree of obstruction was 3.3+/-0.7. For frequency of nasal obstruction, statistical significance was seen among baseline and 4 weeks, 8 weeks, and 1 year (P<.0001, P<.0001, and P<.0001, respectively). There was no difference between 8 weeks and 1 year (P<.15). The pretreatment baseline average frequency of obstruction was 7.8+/-0.5. The remaining frequency of obstruction after 8 weeks was 2.9+/-0.6. The time constant was 18 days. At 1 year, frequency of obstruction was 3.3+/-0.6. Physician assessment of nasal obstruction revealed statistical significance among baseline and 4 weeks, and baseline and 8 weeks (P<.0055 and P<.0056, respectively). There was no difference between 4 weeks and 8 weeks (P<.24). The average initial obstruction was 83%+/-4%. The remaining obstruction after 8 weeks was 58% +/-5%. The time constant was 14 days. Mild pain was reported by 55% of patients during the procedure; the remaining 45% reported no pain. Only one patient required pain medication consisting of acetaminophen after the procedure. There were no significant complications. Degree and frequency of nasal obstruction, as reported by patients, decreased following RF tissue ablation of the inferior turbinates. This improvement in symptoms was still evident after 1 year (P<.001). Physician assessment of obstruction also correlated with patient reports for the initial 8-week study period. The procedure was safe and well tolerated. Thermocouples within the active electrode provided additional feedback to the operating surgeon allowing the use of relatively lower tissue temperatures, power, and energy as compared with traditional techniques. These results support the need for continued research to evaluate this modality as a treatment for chronic nasal obstruction.

Higher rate of statin-related hepatotoxicity has been reported for Koreans than for Westerners. Moreover, statin-related aminotransferase elevation for those who show borderline levels of aspartate transaminase (AST) and alanine transaminase (ALT) (≤×3 of UNL) at baseline has not been fully investigated. Post-statin changes AST/ALT levels during the first year for 21 233 Korean outpatients at two large academic teaching hospitals from January 2009 to December 2013 were analysed using electronic health record data. The date of the first statin prescription was set as baseline. We also performed a comparative analysis of statin-related AST/ALT elevations according to the type of statin, followed by an analysis of clinical risk factors. The progression rate to abnormal AST/ALT values [>×3 the upper normal limit (UNL)] was significantly higher (2·4-16% vs. 0·3-1·7%, P < 0·001) in subjects with borderline (>×1, but ≤×3 of UNL) compared with normal AST/ALT values at baseline. Those with normal baseline AST/ALT did not show significantly different progression rate between different statin medications (P = 0·801). However, patients taking pitavastatin (HR = 0·76, P = 0·657) were least likely to develop abnormal AST/ALT, whereas those taking fluvastatin (HR = 2·96, P = 0·029) were the most likely to develop abnormal AST/ALT compared with atorvastatin for patients who were with baseline borderline AST/ALT. However, given the small sample sizes and the observational nature of our study, these need further study. It is advisable to regularly monitor AST/ALT levels even in patients with AST/ALT increases >×1. Future studies should aim to determine the possible risk factors for each specific statin type by analysing various confounding variables. © 2016 The Authors.

The U.S. federal government recently committed itself to ending chronic homelessness within 5 years. Women constitute one out of four chronically homeless adults and represent a particularly vulnerable group, but have been little studied. To identify potentially unique needs in this group, we report characteristics and 2-year outcomes in a large sample of male and female chronically homeless adults participating in a multisite, supportive housing program. Men and women participating in the outcome evaluation of the 11-site Collaborative Initiative on Chronic Homelessness (n = 714) supportive housing program and who received at least one follow-up assessment were compared on baseline characteristics and up to 2-year follow-up outcomes. Mixed model multivariate regression adjusted outcome findings for baseline group differences. Few significant baseline differences existed between males and females, with both sexes self-reporting very high rates of lifetime mental health (83% women, 74% men) and substance use (68% women, 73% men) problems. Throughout the 2-year follow-up, both men and women dramatically increased the number of days housed, showed minimal changes in substance use patterns, and had modest improvements in mental health outcomes, without significant differences between genders. Unlike other U.S. populations, chronically homeless adults do not demonstrate substantial gender differences on mental health or addiction problems. Policy and service delivery must address these remarkably high rates of substance use and mental illness. Published by Elsevier Inc.

Copeptin levels are elevated in severe medical conditions, an effect that is attributed to elevated arginine vasopressin (AVP) levels in response to physiological stress, resulting in activation of hypothalamus-pituitary-adrenal (HPA) axis. In the current study, we wanted to determine if copeptin is responsive to psychological stress, correlates with cortisol and adrenocorticotropin hormone (ACTH), and if associations differed by sex. In a cross-sectional study that included 100 healthy men (41%) and women (59%) (aged 18-30 years; mean 24.6 ± 3 years), who underwent the Trier Social Stress Test (TSST), we examined the association between percent change (peak-baseline/baseline) in copeptin levels and percent change in log ACTH and cortisol. Three baselines samples were drawn followed by blood sampling at 20, 35, 50, 65 and 85 min after TSST. There was a significant positive association between the percent change in copeptin and the percent change in log-transformed salivary cortisol (β-coefficient=0.95; p=0.02). The association between percent change in copeptin and log-transformed serum cortisol was not statistically significant in the overall population. There was a trend for a non-significant association between percent change in copeptin and percent change in log-transformed ACTH (β-coefficient=1.14; p=0.06). In males, there was a significant positive association between the percent change in copeptin levels and log-transformed salivary (β-coefficient=1.33, p=0.016) and serum cortisol (β-coefficient=0.69, p=0.01), whereas in women there was no statistically significant association. We found a significant positive association between percent change in copeptin and percent change in salivary and serum cortisol among males only. Copyright © 2015 Elsevier Ltd. All rights reserved.

Background It is well accepted that exercise can decrease breast cancer risk. Limited clinical evidence suggests that this risk could be mediated through changes in estrogen metabolism in premenopausal women. Our objective was to investigate the effects of exercise on premenopausal estrogen metabolism pertinent to breast cancer risk. Methods Sedentary, healthy, young eumenorrheic women were randomized into an intervention of 30 minutes of moderate-to-vigorous aerobic exercise 5 times a week for approximately 16 weeks (n = 212), or into a usual-lifestyle sedentary control group (n = 179). Urinary levels of estrogens (estrone [E1], estradiol, and estriol) and nine estrogen metabolites were measured at baseline and at study end by liquid chromatography/tandem mass spectrometry. The ratios of 2-hydroxyestrone to 16α-hydroxyestrone (2-OHE1/16α-OHE1) and 2-OHE1 to 4-hydroxyestrone (2- OHE1/4-OHE1) were also calculated. Results The exercise intervention resulted in significant increases in aerobic fitness and lean body mass, and a significant decrease in percent body fat. For exercisers who completed the study (n = 165), 2-OHE1/16α-OHE1 increased significantly (P = 0.043), while E1 decreased significantly (P = 0.030) in control participants (n = 153). The change from baseline in 2-OHE1/16α-OHE1 was significantly different between groups (P = 0.045), even after adjustment for baseline values. Conclusions The exercise intervention resulted in a significant increase in the 2-OHE1/16α-OHE1 ratio, but no differences in other estrogen metabolites or ratios. Impact Our results suggest that changes in premenopausal estrogen metabolism may be a mechanism by which increased physical activity lowers breast cancer risk. PMID:23652373

Recent studies have demonstrated the beneficial effects of omega-3 polyunsaturated fatty acids (PUFAs) on physiological processes and on a variety of chronic inflammatory diseases, including periodontal diseases. In this study, we evaluated the impact of omega-3 PUFAs in conjunction with scaling and root planing (SRP) on salivary markers in patients with chronic periodontitis. Thirty systemically healthy subjects with chronic periodontitis were enrolled and randomly allocated into two groups. The control group (n = 15) was treated with SRP + placebo whereas the test group was treated with SRP and dietary supplementation of low-dose omega-3 PUFAs (6.25 mg eicosapentaenoic acid and 19.19 mg docosahexaenoic acid). Clinical parameters were taken at baseline, 1, 3 and 6 mo following therapy. Saliva samples were obtained at the same time intervals and analyzed for tumor necrosis factor-α (TNF-α) and superoxide dismutase (SOD). Both groups showed significant changes in clinical parameters in response to treatment compared to baseline with no significant difference between groups. Salivary TNF-α levels showed a statistically significant decrease in the test group at 6 mo compared to the control group. Salivary SOD levels increased significantly at 3 and 6 mo in the test group and at 6 mo in placebo groups compared to baseline with no statistically significant differences between the groups. The results demonstrated that dietary supplementation with low-dose omega-3 PUFAs improves salivary TNF-α without any significant impact on clinical parameters in patients with chronic periodontitis, suggesting that the systemic benefits of dietary omega-3 PUFAs may not be translated to periodontal health.

IMPORTANCE For many older people, long-term functional limitations persist after a hip fracture. The efficacy of a home exercise program with minimal supervision after formal hip fracture rehabilitation ends has not been established. OBJECTIVE To determine whether a home exercise program with minimal contact with a physical therapist improved function after formal hip fracture rehabilitation ended. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial conducted from September 2008 to October 2012 in the homes of 232 functionally limited older adults who had completed traditional rehabilitation after a hip fracture. INTERVENTIONS The intervention group (n = 120) received functionally oriented exercises (such as standing from a chair, climbing a step) taught by a physical therapist and performed independently by the participants in their homes for 6 months. The attention control group (n = 112) received in-home and telephone-based cardiovascular nutrition education. MAIN OUTCOMES AND MEASURES Physical function assessed at baseline, 6 months (ie, at completion of the intervention), and 9 months by blinded assessors. The primary outcome was change in function at 6 months measured by the Short Physical Performance Battery (SPPB; range 0-12, higher score indicates better function) and the Activity Measure for Post-Acute Care (AM-PAC) mobility and daily activity (range, 23-85 and 9-101, higher score indicates better function). RESULTS Among the 232 randomized patients, 195 were followed up at 6 months and included in the primary analysis. The intervention group (n=100) showed significant improvement relative to the control group (n=95) in functional mobility (mean SPPB scores for intervention group: 6.2 [SD, 2.7] at baseline, 7.2 [SD, 3] at 6 months; control group: 6.0 [SD, 2.8] at baseline, 6.2 [SD, 3] at 6 months; and between-group differences: 0.8 [95% CI, 0.4 to 1.2], P < .001; mean AM-PAC mobility scores for intervention group: 56.2 [SD, 7.3] at baseline, 58.1 [SD, 7.9] at 6 months; control group: 56 [SD, 7.1] at baseline, 56.6 [SD, 8.1] at 6 months; and between-group difference, 1.3 [95% CI, 0.2 to 2.4], P = .03; and mean AM-PAC daily activity scores for intervention group: 57.4 [SD, 13.7] at baseline, 61.3 [SD, 15.7] at 6 months; control group: 58.2 [SD, 15.2] at baseline, 58.6 [SD, 15.3] at 6 months; and between-group difference, 3.5 [95% CI, 0.9 to 6.0], P = .03). In multiple imputation analyses, between-group differences remained significant for SPPB and AM-PAC daily activity, but not for mobility. Significant between-group differences persisted at 9 months for all functional measures with and without imputation. CONCLUSIONS AND RELEVANCE Among patients who had completed standard rehabilitation after hip fracture, the use of a home-based functionally oriented exercise program resulted in modest improvement in physical function at 6 months after randomization. The clinical importance of these findings remains to be determined. PMID:24549550

Background: Heavy and/or harmful alcohol use while in college is a perennial and significant public health issue. Despite the plethora of cross-sectional research suggesting deleterious effects of alcohol on the brain, there is a lack of literature investigating the longitudinal effects of alcohol consumption on the adolescent brain. We aim to probe the longitudinal effects of college drinking on gray matter change in students during this crucial neurodevelopmental period. Methods: Data were derived from the longitudinal Brain and Alcohol Research in College Students (BARCS) study of whom a subset underwent brain MRI scans at two time points 24 months apart. Students were young adults with a mean age at baseline of about 18.5 years. Based on drinking metrics assessed at both baseline and followup, subjects were classified as sustained abstainers/light drinkers (N = 45) or sustained heavy drinkers (N = 84) based on criteria established in prior literature. Gray matter volumetric change (GMV-c) maps were derived using the longitudinal DARTEL pipeline as implemented in SPM12. GMV-c maps were then subjected to a 1-sample and 2-sample t-test in SPM12 to determine within- and between-group GMV-c differences in drinking groups. Supplementary between-group differences were also computed at baseline only. Results: Within-group analysis revealed significant decline in GMV in both groups across the 2 year followup period. However, tissue loss in the sustained heavy drinking group was more significant, larger per region, and more widespread across regions compared to abstainers/light drinkers. Between-group analysis confirmed the above and showed a greater rate of GMV-c in the heavy drinking group in several brain regions encompassing inferior/medial frontal gyrus, parahippocampus, and anterior cingulate. Supplementary analyses suggest that some of the frontal differences existed at baseline and progressively worsened. Conclusion: Sustained heavy drinking while in college was associated with accelerated GMV decline in brain regions involved with executive functioning, emotional regulation, and memory, which are critical to everyday life functioning. Areas of significant GMV decreases also overlapped largely with brain reward and stress systems implicated in addictive behavior. PMID:29033801

Evidence from analysing and evaluating examples of three voluntary SEAs prepared in Scotland in the mid-late 1990s showed that different spatial and temporal scales were used when providing a baseline environment description. The SEAs analysed were prepared for: a wind farm siting programme that looked at national and short-term impacts; a land use plan that looked at regional and short-term impacts; and a transport plan that examined local and medium-term impacts. It was found that the two SEAs prepared by local government only considered impacts on the baseline environment within their jurisdictional boundaries whilst the SEA prepared by the privatemore » business considered impacts on the national baseline. A mixture of baseline data about planning, economic, environmental and social issues were included in the SEAs, however, evidence suggested that each SEA only focussed on those baseline features that might be significantly affected by the proposal. Each SEA also made extensive use of existing baseline information available from a variety of sources including local, and central government records and information from statutory bodies. All of the SEAs acknowledged that baseline data deficiencies existed and in certain cases steps were taken to obtain primary field data to help address these, however, it was also acknowledged that resource restrictions and decision-making deadlines limited the amount of primary baseline data that could be collected.« less

A recent prospective randomised trial did not reveal significant differences in median progression-free survival between two chemoradiotherapy (CRT) regimens for inoperable non-metastatic oesophageal cancer patients. This secondary analysis aimed to describe the impact of CRT on health-related quality of life (HRQOL), physical functioning, dysphagia, fatigue and pain and to evaluate whether baseline HRQOL domains can predict overall survival. A total of 267 patients were randomly assigned to receive with 50 Gy of radiotherapy in 25 fractions six cycles of FOLFOX or four cycles of fluorouracil and cisplatin on day 1. HRQOL was prospectively assessed using the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire version 3.0 with the oesophageal cancer module (QLQ-OES18). Both groups showed high baseline compliance. Subsequently, compliance reduced to 41% at the 6-month follow-up. Baseline HRQOL scores showed no statistical differences between treatment arms. During treatment, both groups exhibited lower physical and social functioning and increased fatigue and dyspnoea, although dysphagia moderately improved in the fluorouracil-cisplatin arm only (p = 0.047). During follow-up, HRQOL scores revealed no significant differences between chemotherapy regimens. Linear mixed model exhibited a treatment-by-time interaction effect for dysphagia (p = 0.017) with a greater decrease in dysphagia in the fluorouracil-cisplatin group. Time until definitive deterioration analysis showed no significant differences in global HRQOL, functional or main symptom domains. However, time until definitive deterioration was significantly longer for the fluorouracil and cisplatin arm compared with FOLFOX for appetite loss (p = 0.002), QLQ-OES-18 pain (p = 0.008), trouble swallowing saliva (p = 0.011) and trouble talking (p = 0.020). Analyses of HRQOL scores revealed no statistically significant differences between patients with inoperable non-metastatic oesophageal cancer treated by FOLFOX versus those treated with a fluorouracil-cisplatin regimen as part of definitive CRT.

Dietary patterns characterized by high intakes of fruits and vegetables, whole grains, low-fat dairy products, and low glycemic load have been associated with lower type 2 diabetes mellitus (T2DM) risk. In contrast, dietary patterns that include high intakes of refined grains, processed meats, and high amounts of added sugars have been associated with increased T2DM risk. This randomized, 2-period crossover trial compared the effects of dairy and sugar-sweetened product (SSP) consumption on insulin sensitivity and pancreatic β-cell function in men and women at risk of the development of T2DM who habitually consume sugar-sweetened beverages. In a randomized, controlled crossover trial, participants consumed dairy products (474 mL/d 2% milk and 170 g/d low-fat yogurt) and SSPs (710 mL/d nondiet soda and 108 g/d nondairy pudding), each for 6 wk, with a 2-wk washout between treatments. A liquid meal tolerance test (LMTT) was administered at baseline and the end of each period. Participants were 50% female with a mean age and body mass index of 53.8 y and 32.2 kg/m(2), respectively. Changes from baseline were significantly different between dairy product and SSP conditions for median homeostasis model assessment 2-insulin sensitivity (HOMA2-%S) (1.3 vs. -21.3%, respectively, P = 0.009; baseline = 118%), mean LMTT disposition index (-0.03 vs. -0.36, respectively, P = 0.011; baseline = 2.59), mean HDL cholesterol (0.8 vs. -4.2%, respectively, P = 0.015; baseline = 44.3 mg/dL), and mean serum 25-hydroxyvitamin D [25(OH)D] (11.7 vs. -3.3, respectively, P = 0.022; baseline = 24.5 μg/L). Changes from baseline in LMTT Matsuda insulin sensitivity index (-0.10 vs. -0.49, respectively; baseline = 4.16) and mean HOMA2-β-cell function (-2.0 vs. 5.3%, respectively; baseline = 72.6%) did not differ significantly between treatments. These results suggest that SSP consumption is associated with less favorable values for HOMA2-%S, LMTT disposition index, HDL cholesterol, and serum 25(OH)D in men and women at risk of T2DM vs. baseline values and values during dairy product consumption.

The effect of skipping breakfast on health, especially in adults, remains a controversial topic. A secondary data analysis was conducted to examine associations between breakfast eating patterns and weight loss, nutrient intake, and metabolic parameters among participants with metabolic syndrome (MetS) (n = 240). Three randomly selected 24-h dietary recalls were collected from each participant at baseline and at the one-year visit. Skipped breakfast was seen in 32.9% at baseline and in 17.4% at the one-year visit, respectively. At baseline, after adjustment for demographics and physical activity, participants who ate breakfast had a higher thiamin, niacin, and folate intake than did breakfast skippers (p < 0.05); other selected parameters including body weight, dietary quality scores, nutrient intake, and metabolic parameters showed no significant differences between the two groups (p ≥ 0.05). From baseline to one year, after adjustment for covariates, mean fat intake increased by 2.7% (95% confidence intervals (CI): −1.0, 6.5%) of total energy in breakfast skippers in comparison to the 1.2% decrease observed in breakfast eaters (95% CI: −3.4, 1.1%) (p = 0.02). Mean changes in other selected parameters showed no significant differences between breakfast skippers and eaters (p > 0.05). This study did not support the hypothesis that skipping breakfast has impact on body weight, nutrient intakes, and selected metabolic measures in participants with MetS. PMID:28420112

To examine the effects of a park awareness campaign on park use in 6 community parks. One-group pretest-posttest design. Six community parks located in a South Carolina county. Children, adolescents, and adults observed in community parks. A 1-month awareness campaign that culminated in single 1.5-hour events at 6 parks in April 2011 and May 2011. The System for Observing Play and Recreation in Communities was used to objectively measure park use in May 2010 (baseline) and May 2011 (postcampaign). Zero-inflated Poisson models tested whether the number of total park users and the number of park users engaged in sedentary, walking, and vigorous activities differed by observation date. Park use was significantly greater at baseline than postcampaign (97 vs 84 users, respectively; χ = 4.69, P = .03). There were no significant differences in the number of park users engaged in sedentary (χ = 2.45, P = .12), walking (χ = 0.29, P = .59), and vigorous (χ = 0.20, P = .65) activities between baseline and postcampaign. Although only 97 and 84 people were observed across all parks at baseline and postcampaign, a total of 629 people were observed during the 6 separate 1.5-hour campaign park events. This suggests that there is potential for greater park utilization in these communities, and important questions remain on how to conduct effective awareness campaigns and how to harness interest in park events for the purpose of contributing to future community-wide physical activity and health promotion efforts.

We conducted a systematic review with meta-analysis to evaluate the efficacy of antiviral agents on complete recovery of Bell's palsy. We searched CENTRAL, Embase, MEDLINE, International Pharmaceutical Abstracts, and sources of unpublished literature to November 1, 2014. Primary and secondary outcomes were complete and satisfactory recovery, respectively. To evaluate statistical heterogeneity, we performed subgroup analysis of baseline severity of Bell's palsy and between-study sensitivity analyses based on risk of allocation and detection bias. The 10 included randomized controlled trials (2419 patients; 807 with severe Bell's palsy at onset) had variable risk of bias, with 9 trials having a high risk of bias in at least 1 domain. Complete recovery was not statistically significantly greater with antiviral use versus no antiviral use in the random-effects meta-analysis of 6 trials (relative risk, 1.06; 95% confidence interval, 0.97-1.16; I(2) = 65%). Conversely, random-effects meta-analysis of 9 trials showed a statistically significant difference in satisfactory recovery (relative risk, 1.10; 95% confidence interval, 1.02-1.18; I(2) = 63%). Response to antiviral agents did not differ visually or statistically between patients with severe symptoms at baseline and those with milder disease (test for interaction, P = .11). Sensitivity analyses did not show a clear effect of bias on outcomes. Antiviral agents are not efficacious in increasing the proportion of patients with Bell's palsy who achieved complete recovery, regardless of baseline symptom severity. Copyright © 2015 Elsevier Inc.

The aim of the study was to compare baseline cognitive performance of female in respect to male amateur boxers. Study population included 28 female amateur boxers. Fifty-six male boxers, matched for age, employment and competitive level to female athletes, formed the control group. All boxers had no history of head concussions (except boxing). Each boxer was requested to: 1) fulfill a questionnaire collecting demographic data, level of education, occupational status, boxing record and number of head concussions during boxing; 2) undergo a baseline computerized neuropsychological (NP) test (CogSport) measuring simple and complex reaction times (RT). Female were lighter than male boxers (56±7 vs. 73.1±9.8 kg, P<0.0001). No significant differences at CogSport scores were observed between groups. Male boxers showed a longer simple-RT at the end of the NP battery than at the beginning (0.247±0.007 vs. 0.243±0.007 s, P=0.02), however, with a significant lower rate of mistakes (0.7±1.6 vs. 2.0±3.1%, P=0.005), observed also in the female group (0.5±1.1 vs. 2.2±3.0%, P=0.005). No boxing activity parameter (record, number of knock-outs, etc.) correlated with NP scores. Female and male Olympic-style boxers have no (or minimal) differences in baseline cognitive performance. Further research with larger series of female boxers is required to confirm these findings.

The relationship between exercise and long-term weight loss is definitive. However, in deconditioned individuals, the basis of that relationship beyond minimal energy expenditures is unclear. Effects emanating from exercise's proposed association with changes in emotional eating and its psychosocial correlates were tested. Women with class 1 (n = 67) and class 2 (n = 53) obesity, participating in a new community-based weight-loss treatment based on tenets of social cognitive theory, were assessed at baseline and Months 3, 6, 12, and 24 on weight and measures of exercise outputs, emotional eating, eating self-regulation, and negative mood. An exercise-support component was provided for 2 months prior to group nutrition-change sessions. Improvements from baseline were significant on all measures but did not significantly differ by group. Although not for the initial 3 months, changes in exercise significantly predicted weight changes over 6, 12, and 24 months from baseline. However, only 26%-31% of the lost weight was directly attributable to exercise-related energy expenditures. Changes in emotional eating significantly mediated the exercise-weight-loss relationship, and changes in self-regulation and mood significantly mediated the exercise-emotional eating relationship. Findings supported exercise's role in long-term weight loss primarily through psychosocial factors.

Many alluvial soils along navigable waterways are affected by disposal of dredged sediments or overbank sedimentation and contain metal concentrations that are elevated compared to baseline levels. Uptake patterns for metals and other elements by several volunteer Salix species growing on these sites were determined during a growing season in field plots and compared with the same species growing on soils with baseline contamination levels. For Cd and Zn, foliar concentrations were clearly higher on dredged sediment landfills. Uptake patterns differed significantly between species. A high uptake of Mn and low uptake of Cu, K and S in S. cinerea was attributed to wetland soil chemistry. Site effects on metal uptake were evaluated in more detail for Salix cinerea and S. alba growing on different sediment-derived sites under field conditions. Foliar Cd concentrations were higher in S. cinerea than in S. alba. This appeared to be a genetic feature not influenced by soil chemical properties, as it was observed both on clean sites and polluted sediment-derived sites. For S. cinerea, soil chemistry was reflected in foliar concentrations, while foliar Cd concentrations and bioavailability were found to be independent of the thickness of the polluted horizon. Dredged sediment landfills and freshwater tidal marshes with comparable Cd soil pollution had significantly different foliar Cd concentrations.

Aim To characterize progression of Alzheimer's disease (AD) using proton magnetic resonance spectroscopy (1H MRS). Methods Eleven subjects with mild to moderate AD underwent neurocognitive testing and single-voxel 1H MRS from the precuneus and posterior cingulate region at baseline, after 24 weeks of monotherapy with a cholinesterase inhibitor, and after another 24 weeks of combination therapy with open-label memantine and a cholinesterase inhibitor. Baseline metabolites [N-acetylaspartate (NAA), myo-inositol (mI), choline (Cho), and creatine (Cr)] and their ratios in AD subjects were compared with those of an age-matched control group of 28 cognitively normal subjects. Results AD subjects had significantly higher mI/Cr and lower NAA, NAA/Cr, NAA/Cho, and NAA/mI. Baseline Alzheimer's Disease Cooperative Study Activities of Daily Living (ADCS-ADL) scores significantly correlated with NAA/Cr, mI/Cr, and NAA/mI. There was an increase in mI and a decrease in NAA/mI, but no significant change in other metabolites or ratios, or neurocognitive measures, when memantine was added to a cholinesterase inhibitor. Conclusion Metabolite ratios significantly differed between AD and control subjects. Baseline metabolite ratios correlated with function (ADCS-ADL). There was an increase in mI and a decrease in NAA/mI, but no changes in other metabolites, ratios, or cognitive measures, when memantine was added to a cholinesterase inhibitor. PMID:22962555

This report provides baseline geochemistry for soils (including fill), and for bedrock within three specific areas that are planned for use in the remediation of Material Disposal Area P (MDA-P) at Technical Area 16 (TA-16). The baseline chemistry includes leachable element concentrations for both soils and bedrock and total element concentrations for all soil samples and for two selected bedrock samples. MDA-P operated from the early 1950s to 1984 as a landfill for rubble and debris generated by the burning of high explosives (HE) at the TA-16 Burning Ground, HE-contaminated equipment and material, barium nitrate sand, building materials, and trash.more » The aim of this report is to establish causes for recognizable chemical differences between the background and baseline data sets. In many cases, the authors conclude that recognizable differences represent natural enrichments. In other cases, differences are best attributed to analytical problems. But most importantly, the comparison of background and baseline geochemistry demonstrates significant contamination for several elements not only at the two remedial sites near the TA-16 Burning Ground, but also within the entire region of the background study. This contamination is highly localized very near to the surface in soil and fill, and probably also in bedrock; consequently, upper tolerance limits (UTLs) calculated as upper 95% confidence limits of the 95th percentile are of little value and thus are not provided. This report instead provides basic statistical summaries and graphical comparisons for background and baseline samples to guide strategies for remediation of the three sites to be used in the restoration of MDA-P.« less

Physical activity tracking wearable devices have emerged as an increasingly popular method for consumers to assess their daily activity and calories expended. However, whether these wearable devices are valid at different levels of exercise intensity is unknown. The objective of this study was to examine heart rate (HR) and energy expenditure (EE) validity of 3 popular wrist-worn activity monitors at different exercise intensities. A total of 62 participants (females: 58%, 36/62; nonwhite: 47% [13/62 Hispanic, 8/62 Asian, 7/62 black/ African American, 1/62 other]) wore the Apple Watch, Fitbit Charge HR, and Garmin Forerunner 225. Validity was assessed using 2 criterion devices: HR chest strap and a metabolic cart. Participants completed a 10-minute seated baseline assessment; separate 4-minute stages of light-, moderate-, and vigorous-intensity treadmill exercises; and a 10-minute seated recovery period. Data from devices were compared with each criterion via two-way repeated-measures analysis of variance and Bland-Altman analysis. Differences are expressed in mean absolute percentage error (MAPE). For the Apple Watch, HR MAPE was between 1.14% and 6.70%. HR was not significantly different at the start (P=.78), during baseline (P=.76), or vigorous intensity (P=.84); lower HR readings were measured during light intensity (P=.03), moderate intensity (P=.001), and recovery (P=.004). EE MAPE was between 14.07% and 210.84%. The device measured higher EE at all stages (P<.01). For the Fitbit device, the HR MAPE was between 2.38% and 16.99%. HR was not significantly different at the start (P=.67) or during moderate intensity (P=.34); lower HR readings were measured during baseline, vigorous intensity, and recovery (P<.001) and higher HR during light intensity (P<.001). EE MAPE was between 16.85% and 84.98%. The device measured higher EE at baseline (P=.003), light intensity (P<.001), and moderate intensity (P=.001). EE was not significantly different at vigorous (P=.70) or recovery (P=.10). For Garmin Forerunner 225, HR MAPE was between 7.87% and 24.38%. HR was not significantly different at vigorous intensity (P=.35). The device measured higher HR readings at start, baseline, light intensity, moderate intensity (P<.001), and recovery (P=.04). EE MAPE was between 30.77% and 155.05%. The device measured higher EE at all stages (P<.001). This study provides one of the first validation assessments for the Fitbit Charge HR, Apple Watch, and Garmin Forerunner 225. An advantage and novel approach of the study is the examination of HR and EE at specific physical activity intensities. Establishing validity of wearable devices is of particular interest as these devices are being used in weight loss interventions and could impact findings. Future research should investigate why differences between exercise intensities and the devices exist. ©Erin E Dooley, Natalie M Golaszewski, John B Bartholomew.

Many studies of the relation between factors earlier in life and late-life cognition have a short follow-up time, often less than 10 years. Since cognitive decline can be present up to 20 years prior to dementia it is difficult to distinguish the direction of the relationships without a long follow-up. We analyzed the association between different types of leisure time activity at baseline and cognition more than 20 years later. A wide range of activities was included-political, mental, socio-cultural, social, physical, and organizational activities. Baseline studies were random Swedish samples aged 46-75 years (mean 57.4) (n=1643) interviewed in 1968 or 1981. Activities were measured at baseline. Cognition was measured with items from the Mini-Mental State Examination in 1992, 2002, or 2004. There was a significant association between later cognition and earlier political, mental, and socio-cultural activities controlling for age, age-square, sex, follow-up-time, mobility problems, symptoms of mental distress, employment status, education, adult and childhood socioeconomic status, income, smoking, and drinking. Physical activities had a significant association with cognition only among women. Organizational activities were not significant when controlling for all covariates. Social activities had no significant association. Including all covariates and all leisure activities simultaneously, only mid-life political and mental activities remained significantly related to later life cognition. These findings add support to the theory that various forms of engagement in mid-life can have a protective effect with respect to cognition in later life. Copyright © 2010 John Wiley & Sons, Ltd.

To examine the temporal stability of conditioned pain modulation (CPM), formerly termed diffuse noxious inhibitory controls, among a sample of patients with chronic pain. The study also examined the factors that might be responsible for the stability of CPM. In this test-retest study, patients underwent a series of standardized psychophysical pain-testing procedures designed to assess CPM on two separate occasions (i.e., baseline and follow up). Patients also completed self-report measures of catastrophizing (Pain Catastrophizing Scale [PCS] and negative affect [NA]). Overall, results provided evidence for the stability of CPM among patients with chronic pain. Results, however, revealed considerable sex differences in the stability of CPM. For women, results revealed a significant test-retest correlation between baseline and follow-up CPM scores. For men, however, the test-retest correlation between baseline and follow-up CPM scores was not significant. Results of a Fisher's Z-test revealed that the stability of CPM was significantly greater for women than for men. Follow-up analyses revealed that the difference between men and women in the stability of CPM could not be accounted for by any demographic (e.g., age) and/or psychological factors (PCS and NA). Our findings suggest that CPM paradigms possess sufficient reliability to be incorporated into bedside clinical evaluation of patients with chronic pain, but only among women. The lack of CPM reproducibility/stability observed among men places limits on the potential use of CPM paradigms in clinical settings for the assessment of men's endogenous pain-inhibitory function.

In the Mexican-American population, the prevalence of Type 2 diabetes mellitus (T2DM) is as high as 50% of the population. This randomized controlled clinical trial was designed to elucidate how treatment of periodontal disease affects HbA1c values in this population. One hundred and fifty-four T2DM patients with periodontal disease were enrolled in the study. The test group was treated with scaling and root planing (SRP); the control group received oral hygiene instructions. At baseline and 4-6 weeks after therapy, a complete periodontal examination was performed. Blood was collected at baseline and 4 months later for HbA1c levels. One hundred and twenty-six individuals completed the study. Baseline mean ± SD HbA1c for the test and control groups were 9.0 ± 2.3% and 8.4 ± 2.0% respectively. Non-significant difference in HbA1c reductions (0.6 ± 2.1% and 0.3 ± 1.7%) was found between test and control groups at 4 months. Comparisons of the periodontal clinical parameters between the test and control groups found significant differences with improved results in the test subjects. No statistically significant differences were found in the changes of HbA1c levels between test and control groups. Non-surgical periodontal therapy improved the magnitude of change in periodontal parameters as compared to the control subjects.

This study aimed to evaluate the effectiveness of transcutaneous electrical nerve stimulation (TENS) for treatment of postoperative pain and pulmonary functions (vital capacity [VC]; cough peak flow, [CPF]) in patients who underwent abdominal surgery. Forty-eight patients were randomly allocated to receive TENS, placebo TENS, or no TENS (control) 1 hour a day for 3 days postoperatively. A 0-100 visual analog scale was used to assess pain at preintervention, mid-intervention, and postintervention on the third postoperative day. Pulmonary functions (VC, CPF) were evaluated by spirometer at preoperation (baseline) and at preintervention, mid-intervention, and postintervention on the third postoperative day. One-way analysis of variance was used to assess differences between groups at baseline. Mann-Whitney test was used to compare the control group with the placebo-TENS and TENS group, at each assessment timepoint. Two-way analysis of variance and Bonferroni post hoc test assessed the difference between the 2 (placebo-TENS×TENS) groups. A value of P<0.01 was considered statistically significant. The baselines were not significantly different between any groups. The TENS group had significant reductions in postoperative pain compared with the placebo group (P<0.01) and control group (P<0.01). There was also improvement in pulmonary functions (VC, CPF) at mid-TENS and post-TENS, but not in the placebo-TENS (P<0.01) or control groups (P<0.01). TENS is a valuable treatment to alleviate postoperative pain and improve pulmonary functions (ie, VC, CPF) in patients following abdominal surgery.

Baseline T2* relaxation time has been proposed as an imaging biomarker in cancer, in addition to Dynamic Contrast-Enhanced (DCE) MRI and diffusion-weighted imaging (DWI) parameters. The purpose of the current work is to investigate sources of error in T2* measurements and the relationship between T2* and DCE and DWI functional parameters in breast cancer. Five female volunteers and thirty-two women with biopsy proven breast cancer were scanned at 3 T, with Research Ethics Committee approval. T2* values of the normal breast were acquired from high-resolution, low-resolution and fat-suppressed gradient-echo sequences in volunteers, and compared. In breast cancer patients, pre-treatment T2*, DCE MRI and DWI were performed at baseline. Pathologically complete responders at surgery and non-responders were identified and compared. Principal component analysis (PCA) and cluster analysis (CA) were performed. There were no significant differences between T2* values from high-resolution, low-resolution and fat-suppressed datasets (p > 0.05). There were not significant differences between baseline functional parameters in responders and non-responders (p > 0.05). However, there were differences in the relationship between T2* and contrast-agent uptake in responders and non-responders. Voxels of similar characteristics were grouped in 5 clusters, and large intra-tumoural variations of all parameters were demonstrated. Breast T2* measurements at 3 T are robust, but spatial resolution should be carefully considered. T2* of breast tumours at baseline is unrelated to DCE and DWI parameters and contribute towards describing functional heterogeneity of breast tumours. Copyright © 2018 The Authors.

Our aim was to investigate lubricin, cartilage oligomeric matrix protein (COMP), and femoral cartilage deformation in response to different biomechanical loading of the knee joint (running vs cycling). Serum lubricin and COMP concentrations (enzyme-linked immunosorbent assay), and femoral cartilage thickness (suprapatellar transverse ultrasonography) were determined in 11 male runners (age: 40 ± 6 years; weight: 76 ± 8 kg) and 11 male cyclists (35 ± 12 years; 75 ± 5 kg) at baseline, immediately after, and 30 min after vigorous exercise (time trial: 10-km run or 25-km cycle). At baseline, lubricin (runners: 104.0 ± 19.8 ng/ml; cyclists: 119.1 ± 23.9 ng/ml) and COMP (runners: 804.1 ± 87.5 ng/ml; cyclists: 693.0 ± 84.7 ng/ml) did not significantly differ; however, vigorous exercise was accompanied by an increase in lubricin (cyclists: 39.4 %; p < 0.05; runners: 56.9 %; p < 0.05) and COMP (cyclists: 32.1 %; p < 0.05; runners: 14.2 %; p = 0.14) that returned toward baseline following 30 min of rest (p < 0.05). No between-group differences were observed for baseline cartilage thickness at the intercondyle notch, medial condyle, and lateral condyle, and vigorous exercise did not result in significant change for either group. In the absence of ultrasonographic knee cartilage deformation, the response of serum lubricin and COMP following acute vigorous exercise indicates an increase in joint lubrication and cartilage metabolism, respectively, which appears largely independent of exercise modality.

OBJECTIVE To estimate response of diagnosis and symptom-based subtypes to sertraline treatment. METHODS This was a secondary data analysis for women who were diagnosed with premenstrual syndrome (PMS) or premenstrual dysphoric disorder and treated in three National Institutes of Health-supported clinical trials (N=447). Three PMS subtypes were identified based on predominance of psychological, physical, or both symptom types. Scores for each symptom and a total premenstrual score at baseline and endpoint were calculated from daily symptom diaries. Change from baseline after three treated menstrual cycles (or endpoint if sooner) was estimated using linear regression models adjusted for baseline severity. RESULTS The PMS and premenstrual dysphoric disorder diagnoses improved similarly with sertraline relative to placebo, while symptom-based subtypes had differential responses to treatment. The mixed symptom subtype had the strongest response to sertraline relative to placebo (Daily Symptom Rating [DSR] difference 33.80, 95% CI: 17.16, 50.44, P<0.001), and the physical symptom subtype had the poorest response to sertraline (DSR difference 9.50, 95% CI: −16.29, 35.28, P=0.470). Results based on clinical improvement (50% decrease from baseline) indicated that 8.3 participants in the mixed symptom subtype, 3.9 in the psychological subtype, and 7.1 in the physical subtype are needed to observe one woman in the subtype who would achieve clinical improvement. CONCLUSION The PMS and premenstrual dysphoric disorder diagnoses have similar response to sertraline treatment, but symptom-based subtypes have significantly different responses to this treatment. Mixed and psychological symptom subtypes improved while the physical symptom subtype did not improve significantly. Identifying the patient’s predominant symptoms, and their severity is important for individualized treatment and possible response to a selective serotonin reuptake inhibitor. PMID:22105258

To study the effects of two variants of Roux-en-Y gastric bypass (RYGBP) on plasma ghrelin concentrations according to different exposure of gastric fundus to the nutrient pathway. A prospective longitudinal 2-year follow-up study was conducted. Ninety-six morbidly obese (MO) patients (age range: 41.6 +/- 9.6 years, body mass index: 53 +/- 9.5 kg/m(2)) were assigned to two bariatric surgical (BS) procedures: one that preserves food contact with gastric fundus (ringed RYGBP, n = 50) and the other that avoids it (modified RYGBP, n = 46). Different anthropometric and biochemical parameters were studied, focusing on ghrelin concentrations at baseline and 6, 12, and 24 months post-BS. At 24 months post-BS, all metabolic parameters studied had improved in all patients compared with those at 1-year follow-up and baseline (p < 0.05). However, high-density lipoprotein cholesterol concentrations took 2 years to normalise in 80% of patients, interleukin-6 decreased significantly in relation to baseline only after 2 years from BS (p < 0.001), and tumour necrosis factor alpha concentrations did not significantly decrease during the 2 years of follow-up. Plasma ghrelin concentrations increased in both surgical groups compare to baseline during the first year (24.6% in modified RYGBP and 36.62% in ringed RYGBP) and remained stable at the second year of follow-up, with no statistical differences between groups. In the second year of follow-up after BS, morbidity continued to improve in MO patients despite a lesser weight loss in relation to the first year. An increase in plasma ghrelin concentrations was found, regardless of nutrient contact with gastric fundus. Furthermore, changes in plasma ghrelin concentrations appeared to be independent of weight loss.

Background The wish to return to level I pivoting sports is a major indication of ACL-reconstruction. Patients usually return to pivoting sports between 6 months and 1 year postoperatively, but no matched study has so far examined 1-year return to sport rates in nonoperatively and operatively treated ACL-injured patients. Hypothesis ACL-injured patients following a nonoperative treatment course, including recommendation of activity modification, will have lower return to pivoting sport rates than operatively treated patients 1 year after baseline testing/surgery, when matched by preinjury sports activity, age and sex. Study Design Pair-matched cohort study Methods Sixty-nine nonoperatively treated ACL-injured patients were pair-matched with 69 operatively treated patients (n=138), based on specific preinjury sport, age and sex. Nonoperatively treated patients were recommended not to return to level I sports. Patients were defined as nonoperatively or operatively treated according to their status at follow-up. The baseline and follow-up testing included registration of sports participation, KT-1000 measurements, 4 hop tests, and patient-reported outcome measures. McNemar’s test and paired t-tests or Wilcoxon’s test were used to compare outcomes of nonoperatively and operatively treated patients. Results No significant baseline differences were found. At 12.9±1.2 months (mean ± standard deviation) after baseline testing (nonoperative) and 12.7±1.2 months after surgery (operative), there was no significant difference in overall return to sport rates (nonoperative: 68.1 %, operative: 68.1 %, p=1.000), or in return to level I sport rates (nonoperative: 54.8 %, operative: 61.9 %, p=0.664). Nonoperatively treated patients who participated in level I sports prior to injury had a significantly lower return to sport rate (54.8 %) than nonoperatively treated patients who participated in level II sports (88.9 %, p=0.003). The nonoperatively treated patients had significantly higher knee joint laxity, but significantly better hop test limb symmetry indexes, KOS-ADLS scores, and IKDC 2000 scores. None of the functional differences were larger than the smallest detectable difference. Conclusion ACL-injured patients following a nonoperative treatment course, including recommendations of activity modifications, and operatively treated patients did not have significantly different rates of returning to pivoting sports after 1 year in this pair-matched cohort study. Clinicians should be aware of a potentially high level of noncompliance to recommendations of activity modifications. While these results show that it is possible for nonoperatively treated patients to return to sport after rehabilitation, future follow-ups are needed to examine whether these patients maintain sports participation over time, and what long-term consequences they may suffer regarding subsequent injuries and knee osteoarthritis.

There has been significant discussion surrounding the psychopathology of excessive gaming and whether it constitutes an addiction. The current study investigated physiological and subjective levels of arousal in gamers of two genres and the relationship between sensation seeking and gaming addiction. Heart rate (HR), blood pressure (BP) and skin conductance were recorded at baseline, during gaming for 15 min and after gaming in 30 massively multiplayer online role-playing game (MMORPG) and 30 first-person shooter (FPS) male gamers. Gamers were identified as addicted using the Addiction-Engagement Questionnaire. Sensation seeking was measured using the Arnett Inventory of Sensation Seeking. Addicted MMORPG gamers (n=16) displayed significant decreases in cardiovascular activity during gaming compared to baseline and showed significant increases after gaming. Addicted FPS gamers (n=13) had significant increases in BP during gaming which decreased significantly after gaming. In comparison, non-addicted MMORPG gamers (n=14) had significant decreases in HR during gaming, whereas BP in non-addicted MMORPG and FPS gamers (n=17) increased during gaming and after gaming. There were no significant relationships between sensation seeking and addiction. There are physiological arousal deficits in addicted gamers, and these patterns differ according to the genre of game played. Copyright © 2013 S. Karger AG, Basel.

Objective To identify ethnic differences in HIV risk behaviors among cocaine using women receiving methadone maintenance for opioid dependence, and to evaluate the efficacy of contingency management (CM) for cocaine use disorders in reducing HIV risk behaviors. Methods African American (N=47), Hispanic (N=47), and White women (N = 29) were randomized to standard methadone treatment or standard methadone treatment plus a CM intervention. They completed the HIV Risk Behavior Scale (HRBS) indicating frequency of drug use and sexual behaviors across the lifetime, in the month before baseline, and in the 3 months following clinical trial participation. Ethnic group differences and the effect of CM on change in HIV risk behaviors between baseline and follow-up were evaluated. Results White women reported significantly higher lifetime rates of risky drug use and sexual behaviors on the HRBS than African American women; neither group differed significantly from Hispanic women. No ethnic group differences in HIV risk behaviors were identified in the month prior to baseline. At follow-up, African American women reported fewer high-risk drug use behaviors than White or Hispanic women, and Hispanic women reported more high-risk sexual behaviors than White or African American women. CM was associated with reduction in high-risk drug use behaviors regardless of ethnicity, but did not affect high-risk sexual behaviors. Conclusions White women receiving methadone maintenance engage in more lifetime HIV risk behaviors than African American women. CM for cocaine use reduces risky drug use behaviors, but certain ethnic groups may benefit from additional targeted HIV prevention efforts. PMID:18684571

Background With more than 2 million children living in group homes, or “institutions”, worldwide, the extent to which institution-based caregiving negatively affects development and wellbeing is a central question for international policymakers. Methods A two-stage random sampling methodology identified community representative samples of 1,357 institution-dwelling orphaned and separated children (OSC) and 1,480 family-dwelling OSC aged 6–12 from 5 low and middle income countries. Data were collected from children and their primary caregivers. Survey-analytic techniques and linear mixed effects models describe child wellbeing collected at baseline and at 36 months, including physical and emotional health, growth, cognitive development and memory, and the variation in outcomes between children, care settings, and study sites. Findings At 36-month follow-up, institution-dwelling OSC had statistically significantly higher height-for-age Z-scores and better caregiver-reported physical health; family-dwelling OSC had fewer caregiver-reported emotional difficulties. There were no statistically significant differences between the two groups on other measures. At both baseline and follow-up, the magnitude of the differences between the institution- and family-dwelling groups was small. Relatively little variation in outcomes was attributable to differences between sites (11–27% of total variation) or care settings within sites (8–14%), with most variation attributable to differences between children within settings (60–75%). The percent of variation in outcomes attributable to the care setting type, institution- versus family-based care, ranged from 0–4% at baseline, 0–3% at 36-month follow-up, and 0–4% for changes between baseline and 36 months. Interpretation These findings contradict the hypothesis that group home placement universally adversely affects child wellbeing. Without substantial improvements in and support for family settings, the removal of institutions, broadly defined, would not significantly improve child wellbeing and could worsen outcomes of children who are moved from a setting where they are doing relatively well to a more deprived setting.

To evaluate the effectiveness of 0.07% cetylpyridinium chloride (CPC) mouth rinse for reduction of gingival inflammation and inhibition of plaque compared to a vehicle control (VC) mouth rinse over a 6-month period. Participants (n = 62) used their randomly assigned product as adjunct to toothbrushing. Bleeding, plaque and staining scores were assessed at baseline, 3 and 6 months. Plaque and saliva samples were taken at each assessment monitoring possible shifts in the composition of the microbiota. A significant difference (P = 0.002) in favour of the CPC mouth rinse, with respect to plaque scores, was found. Bleeding scores at 6 months were not significantly different (P = 0.089). However, when correcting for baseline values, a tendency towards a significant difference in bleeding scores at end trail was observed in favour of the CPC mouth rinse (P = 0.061). Regarding staining at 3 and 6 months, a small but significant difference (8.6% and 10.4%, respectively) (P < 0.0001) was observed with lower scores for the VC group. There was a significant reduction in total anaerobic count in the CPC group at 6 months (P < 0.05). The ratio of aerobes/anaerobes was markedly increased at 3 months, especially in the CPC group. No further differences were observed between groups at 6 months. The use of 0.07% CPC mouth rinse was significantly more effective in reducing plaque scores than the vehicle control. Bleeding scores were not different at 6 months. The test product was well accepted and did not cause any serious clinical side effects or negatively affected the microbiota. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

This study aimed to describe the peak vertical force (PVF) over a 1-year period in a stabilized canine cranial cruciate deficient stifle model. Our hypothesis was that PVF would be restored to Baseline (intact) at the end of the follow-up. Fifteen (> 20 kg) mixed-breed dogs were included in this study. Cranial cruciate ligament was transected on Day (D) 0 followed by lateral suture stabilization at D28. Peak vertical force was acquired at D-1, D14, D26, D91, D210 and D357. When compared to Baseline, the PVF was significantly decreased at D14, D26, and D91. Values at D210 and D357 were not statistically different to Baseline. This study suggests a return to normal baseline peak vertical force in a canine cranial cruciate deficient stifle model when lateral suture stabilization has been performed 28 days after surgical transection.

We predict the present-day rates of change of the lengths of 19 North American baselines due to the glacial isostatic adjustment process. Contrary to previously published research, we find that the three-dimensional motion of each of the sites defining a baseline, rather than only the radial motions of these sites, needs to be considered to obtain an accurate estimate of the rate of change of the baseline length. Predictions are generated using a suite of Earth models and late Pleistocene ice histories; these include specific combinations of the two which have been proposed in the literature as satisfying a variety of rebound related geophysical observations from the North American region. A number of these published models are shown to predict rates which differ significantly from the Very Long Base Interferometry (VLBI) observations.

There is a paucity of data related to sports injuries, concussions, and computerized neurocognitive testing (CNT) among very young athletes playing sports in recreational settings. The purpose of this study was to report baseline CNT results among male and female children, ages 5-11, playing sports in Hillsborough County, Florida using ImPACT Pediatric, which is specifically designed for this population. Data were collected from 2016 to 2017. The results show that 657 baseline tests were conducted and t-tests and linear regression were used to assess mean significant differences in composite scores with sex and age. Results showed that females scored better on visual memory and in general as age increased, baseline scores improved. The results can be used to build further studies on the use of CNT in recreational settings and their role in concussion treatment, management, and interventions.

To evaluate the efficacy of a functional microarray of microneedles (MNs) plus topical tranexamic acid (TA) for melasma in middle-aged women in China.Thirty female subjects with melasma were enrolled in this study. The left or right side of the face was chosen randomly to be pretreated with a functional microarray of MNs, followed by topical 0.5% TA solution once per week for 12 weeks. The other half-face was the control, treated with a sham device plus topical 0.5% TA solution. At baseline and at weeks 4, 8, and 12 of treatment, clinical (photographic) evaluations and parameters determined by Visia were recorded. At baseline and week 12, patient satisfaction scores and the biophysical parameters measured by Mexameter were also recorded. Side effects were evaluated at baseline and at the end of the 12 weeks.In total, 28 women (93.3%) completed the study. The brown spots' scores measured by Visia were significantly lower on the combined therapy side than on the control side at 12 weeks after starting treatment; there was no significant difference between sides at 4 or 8 weeks. After 12 weeks, melanin index (MI) decreased significantly in both 2 groups, and the MI was significantly less on the combined side at week 12. Transepidermal water loss, roughness, skin hydration, skin elasticity, and erythema index showed no significant differences between 2 sides at baseline, 4, 8, and 12 weeks after treatment. Physicians' evaluations of photographs showed better results at week 12 with combined therapy: >25% improvement was observed in the MNs plus TA side in 25 patients, and in the TA side in only 10 patients. Subjective satisfaction scores on both sides increased significantly. The participants were more satisfied with the results of the combined therapy side than the control side. No obvious adverse reactions were observed throughout the study.Combined therapy with a functional microarray of MNs and topical TA solution is a promising treatment for melasma.

To identify baseline predictors of worsening renal function (WRF) in an acute decompensated heart failure (ADHF) patient population receiving continuous infusion loop diuretics. Retrospective observational analysis. Academic tertiary medical center. A total of 177 patients with ADHF receiving continuous infusion loop diuretics from January 2006 through June 2009. The mean patient age was 61 years, 63% were male, ~45% were classified as New York Heart Association functional class III, and the median length of loop diuretic infusion was 4 days. Forty-eight patients (27%) developed WRF, and 34 patients (19%) died during hospitalization. Cox regression time-to-event analysis was used to determine the time to WRF based on different demographic and clinical variables. Baseline serum albumin 3 g/dl or less was the only significant predictor of WRF (hazard ratio [HR] 2.87, 95% confidence interval [CI] 1.60-5.16, p=0.0004), which remained significant despite adjustments for other covariates. Serum albumin 3 g/dl or less is a practical baseline characteristic associated with the development of WRF in patients with ADHF receiving continuous infusion loop diuretics. © 2013 Pharmacotherapy Publications, Inc.

Research indicates that the ability to perform a task can be affected by the composition of the meal preceding the task. This study investigated the effect of shift workers' consumption of a medium-fat, medium-carbohydrate meal on alertness scores. Six subjects (four men, two women) aged 19 to 44 recorded food intake, sleep, and quality of sleep for two weeks, and measured their body temperature and performed cognitive tests during two night shifts at baseline and in test periods. The Stanford Sleepiness Scale (SSS) was used to quantify sleepiness, and a Paced Auditory Serial Addition Test (PASAT) was used to measure cognitive performance. In comparison with the score at baseline, when subjects had a low-fat, high-carbohydrate dietary intake (1,335 kcal/5,588 kJ, 56% carbohydrate, 28% fat), the 1.6-second PASAT score improved significantly (p=0.042) during night shifts when subjects consumed a test meal (987 kcal/4,131 kJ, 46% carbohydrate, 42% fat). No statistically significant difference in SSS was found between baseline and test periods. The reduced body temperature between 2400 hours and 0530 hours was similar for both baseline and test periods. Meal composition and size during night shifts may affect cognitive performance.

Sports-related concussions (SRC) among high school and collegiate athletes represent a significant public health concern. The Concussion in Sport Group (CIS) recommended greater caution regarding return to play with children and adolescents. We hypothesized that younger athletes would take longer to return to neurocognitive baseline than older athletes after a SRC. Two hundred adolescent and young adult athletes who suffered a SRC were included in our clinical research cohort. Of the total participants, 100 were assigned to the 13-16 year age group and 100 to the 18-22 year age group and were matched on the number of prior concussions. Each participant completed baseline and postconcussion neurocognitive testing using the Immediate Post-Concussion assessment and Cognitive Testing (ImPACT) test battery. Return to baseline was defined operationally as post-concussion neurocognitive and symptom scores being equivalent to baseline using reliable change index (RCI) criteria. For each group, the average number of days to return to cognitive and symptom baseline were calculated. Independent sample t-tests were used to compare the mean number of days to return to baseline. Significant differences were found for days to return to baseline between 13-16 year olds and 18-22 year olds in three out of four neurocognitive measures and on the total symptom score. The average number of days to return to baseline was greater for 13-16 year olds than for 18-22 year olds on the following variables: Verbal memory (7.2 vs. 4.7, P = 0.001), visual memory (7.1 vs. 4.7, P = 0.002), reaction time (7.2 vs. 5.1 P = 0.01), and postconcussion symptom scale (8.1 vs. 6.1, P = 0.026). In both groups, greater than 90% of athletes returned to neurocognitive and symptom baseline within 1 month. Our results in this clinical research study show that in SRC, athletes 13-16 years old take longer to return to their neurocognitive and symptom baselines than athletes 18-22 years old.

The metabolic syndrome (MetS) is a precursor of diabetes. Physical activity (PA) improves endothelial dysfunction and may benefit patients with MetS. Aims. To evaluate the effect of a physical activity (PA) program on markers of endothelial dysfunction and oxidative stress in adolescents with (MetS). Methods. We carried out a cohort study of 38 adolescents with and without MetS (18 females and 20 males). All participants completed a 3-month PA program. All variables of the MetS as well as markers of endothelial dysfunction and oxidative stress tests were evaluated. Results. Females with and without MetS showed significant differences for almost all components of the MetS, whereas males were significantly different in half of the components. After the PA program, components of the MetS were not different from baseline values except for HDL-C levels. Some baseline endothelial dysfunction markers were significantly different among adolescents with and without MetS; however, after the PA program, most of these markers significantly improved in subjects with and without MetS. Conclusion. PA improves the markers of endothelial dysfunction in adolescents with MetS although other changes in the components of the MetS were not observed. Perhaps the benefits of PA on all components of MetS would appear after a PA program with a longer duration. PMID:22888450

Microvascular reconstructive surgery has seen a revival with the introduction of muscle-sparing perforator flaps. Recognition of potential ethnic differences in coagulation profiles would be important to a microvascular surgeon. Based on clinical observations, we hypothesize that Asian patients have a less thrombogenic coagulation profile than Caucasians. An extensive retrospective review was performed. The annual incidence of venous thromboembolism in the United States is generally accepted to range from 70 to 120 events per 100,000 people versus 16 to 17 events per 100,000 persons in Asia. Autopsy analysis of pulmonary embolism incidence was noted to be 15% in North Americans and less than 1% in Asian populations. Thromboelastography analysis of Asian and Caucasian patients undergoing cholecystectomy revealed different hemostatic mechanisms. Comparison of Asians and Caucasians undergoing the Fontan procedure revealed significantly lower postoperative factor levels in Asians than Caucasians. Baseline comparison of factor and serum levels revealed Asians with the least thrombogenic profiles compared with other ethnic groups. Asians and Caucasians demonstrate different baseline rates of deep vein thrombosis and pulmonary embolism, different hemostatic responses to surgery, and different baseline levels of clotting factors. Further study may lead to better pre-, intra-, and postoperative care of the free flap patient based on their ethnic coagulation profile. © Thieme Medical Publishers.

The relationship between beta2-adrenoceptor polymorphisms at positions 16 and 27, and the acute systemic beta2-adrenoceptor effects of inhaled salbutamol is unclear. We therefore elected to evaluate the influence of common homozygous beta2-adrenoceptor haplotypes on the acute systemic beta2-adrenoceptor effects following inhaled salbutamol in asthmatic subjects. An initial database search of 531 asthmatic subjects identified the two commonest homozygous haplotypes at positions 16 and 27 to be Arg16-Gln27 (12%) and Gly16-Glu27 (19%). After a 1-week washout period where all beta2-adrenoceptor agonists were withdrawn, 16 Caucasian subjects (Arg16-Gln27: n = 8 and Gly16-Glu27: n = 8) were given a single dose of inhaled salbutamol (1200 microg), followed by serial blood sampling for serum potassium, along with measurements of diastolic blood pressure and heart rate, at 5-min intervals for 20 min. The two groups were well matched for age, sex, FEV1, and inhaled corticosteroid dose. Baseline values for serum potassium, diastolic blood pressure and heart rate were not significantly different comparing Arg16-Gln27 vs Gly16-Glu27. The mean +/- SEM maximum serum potassium change from baseline over 20 min was significantly greater (P = 0.04) for Arg16-Gln27: -0.37 +/- 0.05 mmol l(-1) vs Gly16-Glu27: -0.23 +/- 0.04 mmol l(-1); 95% CI for difference: -0.01 to -0.28 mmol l(-1). The maximum diastolic blood pressure change from baseline over 20 min was significantly greater (P = 0.0008) for Arg16-Gln27: -13 +/- 1 mmHg vs Gly16-Glu27: -4 +/- 2 mmHg; 95% CI for difference: -5, 14 mmHg. There was no significant difference comparing the maximum heart rate change from baseline for Arg16-Gln27: 10 +/- 3 beats min(-1) vs Gly16-Glu27: 10 +/- 3 beats min(-1). Caucasian asthmatic subjects with the Arg16-Gln27 haplotype exhibited a greater systemic response to inhaled salbutamol, compared with those with the Gly16-Glu27 haplotype. The attenuated beta2-adrenoceptor response in the Gly16-Glu27 haplotype would be in keeping with increased susceptibility to prior down-regulation by endogenous catecholamines.

I evaluated the effectiveness of the California Tri-Pull Taping method for clients with poststroke inferior shoulder subluxation of the glenohumeral joint. Ten participants were followed for 9 wk using an interrupted time series quasi-experimental single-subject ABA design to examine shoulder pain, activities of daily living (ADL) function, active range of motion, tape comfort, and subluxation. The California Tri-Pull Taping method decreased inferior subluxation significantly from baseline to intervention but not at postintervention. Active range of motion was significantly increased in shoulder flexion and abduction between the baseline and intervention and the intervention and postintervention phases. Functional ADL scores were significant. The taping was reported to be comfortable. No significant difference in pain was found. This intervention is a promising adjunct to the management of the hemiplegic subluxed shoulder that warrants further research. Copyright © 2012 by the American Occupational Therapy Association, Inc.

Hydrotherapy (immersion or bathing) is used worldwide to promote relaxation and decrease parturient anxiety and pain in labor, but the psychophysiological effects of this intervention remain obscure. A pretest-posttest design with repeated measures was used to examine the effects of hydrotherapy on maternal anxiety and pain, neuroendocrine responses, plasma volume shift (PVS), and uterine contractions (CXs) during labor. Correlations among variables were examined at three time points (preimmersion and twice during hydrotherapy). Eleven term women (mean age 24.5 years) in spontaneous labor were immersed to the xiphoid in 37 degrees C water for 1 hr. Blood samples and measures of anxiety and pain were obtained under dry baseline conditions and repeated at 15 and 45 min of hydrotherapy. Uterine contractions were monitored telemetrically. Hydrotherapy was associated with decreases in anxiety, vasopressin (V), and oxytocin (O) levels at 15 and 45 min (all ps < .05). There were no significant differences between preimmersion and immersion pain or cortisol (C) levels. Pain decreased more for women with high baseline pain than for women with low baseline levels at 15 and 45 min. Cortisol levels decreased twice as much at 15 min of hydrotherapy for women with high baseline pain as for those with low baseline pain. beta-endorphin (betaE) levels increased at 15 min but did not differ between baseline and 45 min. During immersion, CX frequency decreased. A positive PVS at 15 min was correlated with contraction duration. Hydrotherapy during labor affects neuroendocrine responses that modify psychophysiological processes.

To examine the effect of radiotherapy for bone metastases on urinary markers of osteoclast activity. Patients with radiological evidence of bone metastases planned for palliative radiotherapy were eligible for the study. A urine specimen was collected before and 1 month after radiotherapy to assess levels of calcium, creatinine, magnesium, phosphate, N-telopeptide and pyridinoline. The Brief Pain Inventory was completed in person at baseline and by telephone follow-up at 1 month after radiotherapy. Patients were classified as responders (complete or partial pain response) or non-responders (stable or progressive pain) to radiotherapy based on the International Bone Metastases Consensus Criteria for end point measurements. Absolute values of urine markers were compared between responders and non-responders, or between responders and patients with progression. Our study population consisted of 74 men and 51 women. A single 8 Gy or 20 Gy in five daily fractions were commonly employed. At the 1 month follow-up, all Brief Pain Inventory functional interference scores showed a highly significant decrease from baseline (P<0.01). From our study population, 58 (64%) were classified as responders and 57 (46%) as non-responders to radiotherapy. We compared the urinary markers between the responders and the non-responders. There were no statistically significant differences between the two groups either in terms of baseline markers or in terms of month 1 follow-up markers. There was no significant change from baseline to the 1 month follow-up in responders or in non-responders to radiotherapy. Baseline levels of urinary markers could not predict which patient would benefit from palliative radiotherapy.

Circadian phase resetting is sensitive to visual short wavelengths (450–480 nm). Selectively filtering this range of wavelengths may reduce circadian misalignment and sleep impairment during irregular light-dark schedules associated with shiftwork. We examined the effects of filtering short wavelengths (<480 nm) during night shifts on sleep and performance in nine nurses (five females and four males; mean age ± SD: 31.3 ± 4.6 yrs). Participants were randomized to receive filtered light (intervention) or standard indoor light (baseline) on night shifts. Nighttime sleep after two night shifts and daytime sleep in between two night shifts was assessed by polysomnography (PSG). In addition, salivary melatonin levels and alertness were assessed every 2 h on the first night shift of each study period and on the middle night of a run of three night shifts in each study period. Sleep and performance under baseline and intervention conditions were compared with daytime performance on the seventh day shift, and nighttime sleep following the seventh daytime shift (comparator). On the baseline night PSG, total sleep time (TST) (p < 0.01) and sleep efficiency (p = 0.01) were significantly decreased and intervening wake times (wake after sleep onset [WASO]) (p = 0.04) were significantly increased in relation to the comparator night sleep. In contrast, under intervention, TST was increased by a mean of 40 min compared with baseline, WASO was reduced and sleep efficiency was increased to levels similar to the comparator night. Daytime sleep was significantly impaired under both baseline and intervention conditions. Salivary melatonin levels were significantly higher on the first (p < 0.05) and middle (p < 0.01) night shifts under intervention compared with baseline. Subjective sleepiness increased throughout the night under both conditions (p < 0.01). However, reaction time and throughput on vigilance tests were similar to daytime performance under intervention but impaired under baseline on the first night shift. By the middle night shift, the difference in performance was no longer significant between day shift and either of the two night shift conditions, suggesting some adaptation to the night shift had occurred under baseline conditions. These results suggest that both daytime and nighttime sleep are adversely affected in rotating-shift workers and that filtering short wavelengths may be an approach to reduce sleep disruption and improve performance in rotating-shift workers.

[Purpose] The purpose of the present study was to compare the postural sway of healthy adults standing on different types of balance pads. [Subjects and Methods] Nine healthy adults participated in this study. Postural body sway was measured while participants were standing on four different types of balance pads: Balance-pad Elite (BE), Aero-Step XL (AS), Dynair Ballkissen Senso (DBS), and Dynair Ballkissen XXL Meditation and Yoga (DBMY). A Wii Balance Board interfaced with Balancia software was used to measure postural body sway. [Results] In the sway velocity, sway path length, and sway area, no significant differences were found between baseline conditions (participants were standing on the floor with no balance pad) and the use of the BE or AS. However, significant increases in all parameters were found comparing baseline conditions to the use of either Dynair balance pad. Furthermore, the use of either Dynair balance pad significantly increased postural sway compared to both the BE and the AS. [Conclusion] These findings suggest that the DBS and DBMY balance pads may serve as superior tools for providing unstable condition for balance training than the BE and the AS balance pads.

Although hyperuricemia and insulin resistance significantly correlated, their temporal sequence and how the sequence influence on future risk of hypertension are largely unknown. This study assessed temporal relationship between uric acid and insulin resistance and its impact on future risk of hypertension by examining a longitudinal cohort including 8543 subjects aged 20 to 74 years from China, with an average follow-up of 5.3 years. Measurements of fasting uric acid, as well as fasting and 2-hour serum glucose and insulin, were obtained at baseline and follow-up. Indicators of hepatic and peripheral insulin resistance were calculated. Cross-lagged panel and mediation analysis were used to examine the temporal relationship between uric acid and insulin resistance and its impact on follow-up hypertension. After adjusting for covariates, the cross-lagged path coefficients ( β 1 values) from baseline uric acid to follow-up insulin resistance indices were significantly greater than path coefficients ( β 2 values) from baseline insulin resistance indices to follow-up uric acid ( β 1 =0.110 versus β 2 =0.017; P <0.001, for hepatic insulin resistance; β 1 =-0.208 versus β 2 =-0.021; P <0.001, for peripheral insulin resistance). The path coefficients from baseline uric acid to follow-up insulin resistance indices in the hypertensive group were significantly greater than that in the normotensive group ( P <0.001 for the difference of β 1 values in the 2 groups). Insulin resistance partially mediated the effect of uric acid on subsequent hypertension, and the mediation effect of peripheral insulin resistance was significantly greater than that of hepatic insulin resistance (31.3% versus 13.2%; P <0.001, for the difference of mediation effects). These findings provide evidence that higher uric acid levels probably precede insulin resistance, and peripheral insulin resistance likely plays a more important role in the development of hypertension than hepatic insulin resistance does. © 2017 American Heart Association, Inc.

Circadian rhythmicity and non-visual sensitivity to light can be assessed, in healthy subjects, by measuring the rhythm of the urinary melatonin metabolite 6-sulphatoxymelatonin (aMT6s) and by determining the response of plasma melatonin to nocturnal retinal light exposure, respectively. However, the validity of these techniques has not been assessed in disease states in which disruption of the circadian rhythm is known or suspected to occur. Thus, the aims of this study were as follows: (i) to assess the reliability of circadian aMT6s profile estimates derived from 36 h versus 56 h urine collections and (ii) to test different models for calculating melatonin suppression in response to light in healthy volunteers and patients with cirrhosis. Twenty patients with biopsy-proven cirrhosis and 10 matched healthy volunteers undertook: (i) separate 36 - and 56-h urine collections, under controlled conditions, for cosinor analysis of the urinary aMT6s profile; (ii) a melatonin suppression test, comprising of a baseline night, during which subjects were woken and asked to sit in front of a switched off light sphere, and an experimental night, identically executed, except that the light sphere was switched on and the subjects were exposed to white light (4.1 × 10(14) photons/cm(2)/s) for 30 min. Alternative approaches to the calculation of melatonin suppression were taken, with/without inclusion of the baseline night. Eighteen patients and eight healthy volunteers had matched analysable 36 - and 56-h urinary samples. Cosinor analysis showed a significant fit in 88% of the remaining 56 h collections, and 48% of the remaining 36-h collections. Thus, eight patients and five healthy volunteers had matched analysable samples for cosinor analysis. In the healthy volunteers, aMT6s profile indices obtained using the 36 - and the 56-h collections did not differ significantly. In contrast, considerably more variability was observed in patients [i.e. the difference in the aMT6s peak time was 0.5 ± 1.7 h (limits of agreement: -3.9; +2.9 h)]. No difficulties were encountered in obtaining suppression estimates by use of the experimental night only. In contrast, suppression estimates obtained by use of both nights were considered inaccurate in one (11%) healthy volunteer and in 5 (28%) patients, primarily because: (i) melatonin concentrations at the beginning of light administration were significantly different on baseline and experimental night; (ii) the rise in melatonin was inconsistent on baseline night; and (iii) the shape of the rising phase of melatonin was different on baseline and experimental night. In conclusion, shorter urine collections lead to a higher number of profiles with no significant cosinor fit, and differences in cosinor indices obtained from the 36 - and 56-h collections were considerable, especially in patients. Thus, 56-h collections are probably advisable. Use of both baseline and experimental nights to calculate melatonin suppression often resulted in increased variation and confounding, due to point oscillations in melatonin concentration and lack of repeatability of the melatonin profiles on the two nights. Thus, use of the experimental night only is probably advisable.

Strain differences in immobility time in the forced swimming test were investigated in five strains of mice, namely, ICR, ddY, C57BL/6, DBA/2 and BALB/c mice. There were significant strain differences. The immobility times of ICR, ddY and C57BL/6 mice were longer than those of DBA/2 and BALB/c mice. Immobility times were not significantly related to locomotor activity in these strains. There were also differences in sensitivity to the selective serotonin reuptake inhibitor (SSRI) fluvoxamine. In ICR, ddY and C57BL/6 mice, fluvoxamine did not affect immobility time, while it reduced the immobility time of DBA/2 and BALB/c mice dose-dependently. The noradrenaline reuptake inhibitor desipramine decreased immobility time in all strains of mice. Serotonin (5-HT) transporter binding in the brains of all five strains of mice was also investigated. Analysis of 5-HT transporter binding revealed significant strain differences, being lower in DBA/2 and BALB/c mice than in other strains of mice. The amount of 5-HT transporter binding was correlated to baseline immobility time. However, there was no significant relation between noradrenaline transporter binding and immobility time. These results suggest that the duration of baseline immobility depends on the levels of 5-HT transporter binding, leading to apparent strain differences in immobility time in the forced swimming test. Furthermore, differences in 5-HT transporter binding may cause variations in responses to fluvoxamine.

Assessment of microbial parameters, viz. microbial biomass, fluorescence diacetate, microbial respiration, acid phosphatase, beta-glucosidase and urease with respect to acidity helps in evaluating the quality of soils. This study was conducted to investigate the effects of different forms of acidities on soil microbial parameters in an acid mine drainage contaminated site around coal deposits in Jainta Hills of India. Total potential and exchangeable acidity, extractable and exchangeable aluminium were significantly higher in contaminated soil compared to the baseline (p<0.01). Different forms of acidity were significantly and positively correlated with each other (p<0.05). Further, all microbial properties were positively and significantly correlated with organic carbon and clay (p<0.05). The ratios of microbial parameters with organic carbon were negatively correlated with different forms of acidity. Principal component analysis and cluster analyses showed that the microbial activities are not directly influenced by the total potential acidity and extractable aluminium. Though acid mine drainage affected soils had higher microbial biomass and activities due to higher organic matter content than those of the baseline soils, the ratios of microbial parameters/organic carbon indicated suppression of microbial growth and activities due to acidity stress. 2010 Elsevier B.V.

Topical minoxidil and oral finasteride have been used to treat men with androgenetic alopecia (AGA). There are concerns about side effects of oral finasteride especially erectile dysfunction. To compare the efficacy and safety of the 24 weeks application of 3% minoxidil lotion (MNX) versus combined 3% minoxidil and 0.1% finasteride lotion (MFX) in men with AGA. Forty men with AGA were randomized treated with MNX or MFX. Efficacy was evaluated by hair counts and global photographic assessment. Safety assessment was performed by history and physical examination. At week 24, hair counts were increased from baseline in both groups. However paired t-test revealed statistical difference only in MFX group (p = 0.044). Unpaired t-test revealed no statistical difference between two groups with respect to change of hair counts at 24 weeks from baseline (p = 0.503). MFX showed significantly higher efficacy than MNX by global photographic assessment (p = 0.003). There was no significant difference in side effects between both groups. Although change of hair counts was not statistically different between two groups, global photographic assessment showed significantly greater improvement in the MFX group than the MNX group. There was no sexual side effect. MFX may be a safe and effective treatment option.

Objective This study assessed the efficacy of the Marriage Checkup for improving relationship health and intimacy. Method Cohabiting married couples (N=215, Mage women=44.5 years, men=47 years, 93.1% Caucasian) recruited from a northeastern U.S. metropolitan area through print and electronic media were randomly assigned to MC treatment or wait-list control. Treatment but not control couples participated in assessment and feedback visits, at the beginning of the study and again one year later. All couples completed nine sets of questionnaires over two years. Outcome measures included the Quality of Marriage Index, the Global Distress subscale of the Marital Satisfaction Inventory-Revised, the Intimate Safety Questionnaire, and the Relational Acceptance Questionnaire. Results A latent growth curve model indicated significant between group differences in intimacy at every measurement point after baseline (d ranged from .20 to .55, Md = .37), significant between group differences in women’s felt acceptance for every measurement point after baseline (d ranged from .17 to .47, Md = .34), significant between group differences in men’s felt acceptance through the 1-year-2 week follow-up (d across follow-up ranged from .11 to .40, Md = .25), and significant between group differences in relationship distress through 1-year 6-month follow-up (d across follow-up ranged from .11 to .39, Md = .23). Conclusions Longitudinal analysis of the MC supports the hypothesis that the MC significantly improves intimacy, acceptance, and satisfaction. Implications for dissemination are discussed.
