    We evaluated the efficacy of voice therapy according to Borragan's method associated to S. Magnani's vocal counselling in functional dysphonia in children. We prospectively treated 16 patients with vocal fold nodules (10 males, 6 females). Age ranged from 6 to 11 years with a mean age of 9 years. We performed a full screening phoniatric evaluation. In addition psychological tests were carried out to investigate psychological background. We lost three patients at follow-up; one patient received surgery, eight patients healed (43.75%), four improved (25%). There was no statistical difference in the analysis of electroacoustical parameters while MPT significatively raised after therapy. If patients have motivation voice therapy could improve functional dysphonia in children. It is also important psychological background. Further studies on bigger populations with long-term follow-up are needed.

    This study aimed to determine bowel function changes 12 months after robotic sacrocolpopexy. We performed a single-center prospective cohort study evaluating bowel function 12 months after robotic sacrocolpopexy between 2007 and 2011. Bowel function symptoms were measured by the Colorectal-Anal Distress Inventory, Short Form 8 (CRADI-8). Specific impacts on quality of life with regard to bowel function were evaluated using the Colorectal-Anal Impact Questionnaire, Short Form 7 (CRAIQ-7). "Splinting to defecate" was defined as any positive response to question 4 of the Pelvic Floor Distress Inventory-20 which reads, "do you ever have to push on the vagina or around the rectum to have or complete a bowel movement?." Lastly, patients were grouped according to perineorrhaphy versus no perineorrhaphy and bowel function scores were examined. Of 423 consecutive patients who underwent robotic sacrocolpopexy at our institution, 393 (93%) completed a 12-month follow-up. Mean CRADI-8 scores at baseline and 12 months were 21.1 (20) and 7.3 (11), respectively (P < 0.0001). Mean CRAIQ-7 scores at baseline and 12 months were 11.1 (20) and 2.4 (9), respectively (P < 0.0001). Preoperatively, 152 patients reported a need to splint the vagina or perineum to complete a bowel movement. At 12 months, 70% reported complete resolution of "splinting." Con comitant perineorrhaphy was performed on 87 patients and there were no differences in 12-month CRADI-8 or CRAIQ-7 scores between groups. Robotic sacrocolpopexy was associated with significant improvements in bowel function as measured by CRADI-8 as well as improvements in impact on quality of life as measured by CRAIQ-7.

    In a short term prospective study 70 male lead workers performed a series of cognitive tasks on three occasions during an eight month period. Concurrently with the cognitive testing, the concentrations of blood lead, zinc protoporphyrin (ZPP) and urinary aminolaevulinic acid (ALA) were measured. Indicators of lead absorption were stable during the study and each subject was allocated to either a low (below 20 micrograms/dl), medium (21-40 micrograms/dl), or high (41-80 micrograms/dl) group on the basis of their average blood lead concentrations. Performance deficits tended to be restricted to the high lead group and, in general, neither practice nor continued exposure during the study altered the magnitude of these deficits. The main deficit was a slowing of sensory motor reaction time, which was seen most clearly when the cognitive demands of the task were low. In the cognitively simple five choice task, blood lead concentration correlated with impaired decision making, response execution, and "lapses in concentration." In the other cognitive tasks the high blood lead group tended also to be slower by a factor of about 1.08 but the dominance of cognitive over sensory motor demands attenuated the exposure-performance correlations. The high lead group also had difficulty in recalling nouns poorly related to the focus of an earlier semantic classification task. This difficulty increased over time and was one of the few findings that correlated with all measures of lead absorption. It is concluded that the primary psychological profile of lead impairment is one of sensory motor slowing coupled with difficulties in remembering incidental information. PMID:1954152

    Few studies have prospectively assessed functional outcomes after the surgical management of supracondylar humerus fractures (SCHFXs) and the relationship between fracture pattern and ultimate patient outcome has never been prospectively evaluated. The purpose of this study was to prospectively evaluate fracture classification and functional outcome in children with extension SCHFXs using validated outcome measures. An Institutional Review Board-approved prospective enrollment of consecutive patients with operative SCHFX was performed over a 3-year period. Fractures were classified by the treating surgeon using the modified Gartland classification. Functional outcome was assessed at final follow-up using the Pediatric Outcomes Data Collection Instruments (PODCI) and the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) outcome measure. Patients with flexion-type fractures, multidirectionally unstable fractures and those with <10 weeks follow-up were excluded from analysis. Statistical analysis was used to determine the relationship between fracture classification/pattern and functional outcome. Seven hundred fifty-two patients were enrolled during the study period. One hundred thirty-two patients with extension-type injuries (average age 6.7 y) completed functional outcome measures at an average follow-up of 12.4 weeks. Forty-five (34%) were type II fractures and 87 (66%) were type III fractures. Forty-five (34%) of the fractures were posteromedially displaced, 43 (33%) were posterolaterally displaced, and 44 (33%) were posteriorly displaced without coronal plane deformity. The average PODCI global functioning scale score and QuickDASH scores for the entire cohort were 93.6 and 11.4, respectively, indicating excellent function. No differences in outcome scores were noted between patients with type II and III fractures. No difference in outcome was identified based upon direction of fracture displacement. This is the first study to prospectively analyze

    Emotional dysfunction is by definition central to personality disorders (PDs). In the alternative model in DSM-5, self and relational dysfunctioning constitutes the core of PD, but little is known about the relation between emotional functioning and such core aspects of personality functioning. This study investigated concurrent and prospective associations between emotional and personality functioning as assessed by affect consciousness (AC) and the Severity Indices of Personality Problems (SIPP-118), respectively. The SIPP-118 comprises five domains of personality functioning, including Identity Integration and Relation Capacities, and was applied repeatedly during 3-year follow-up of 63 PD patients who participated in a treatment study. Statistical analyses were based on linear mixed models. Lower AC levels were significantly associated with (a) lower levels of Identity Integration and Relational Capacities at baseline, and (b) poorer long-term improvement of Identity Integration. The study supports the notion that affect consciousness is related to core aspects of personality functioning.

  6. Functional outcome of pyeloplasty for ureteropelvic junction obstruction: Prospective study in 30 consecutive cases

    In a prospective study of 50 consecutive patients with urographic renal pelvic dilatation, 30 with genuine ureteropelvic junction obstruction identified by 123-iodine-hippurate diuretic renal scanning (renography) were treated by dismembered pyeloplasty. One patient with reduced preoperative function required secondary nephrectomy. Three patients with normal function in solitary kidneys had unchanged postoperative function. In the remaining 26 patients preoperative function measured by diuretic renal scanning was compared to 6-month postoperative values. If split function changes of less than 5 per cent were considered insignificant, to allow for inherent statistical errors of renal scanning, preoperative function was decreased in 18 patients, improved postoperatively in 10 and remained the same in 8. In 8 patients preoperative function was normal and remained so postoperatively. Drainage improved in 22 of the 26 patients and was unchanged in 4. Analysis of functional change by Student's t test and the Wilcoxon paired sums test showed significant improvement in mean and median function (p less than 0.001), with the degree of improvement being greatest in patients with the most severely depressed preoperative levels. In addition to producing significant improvement in drainage in ureteropelvic junction obstruction, pyeloplasty arrests functional deterioration in almost every case and improves function significantly in the majority.

    The Latarjet procedure provides effective stabilization of chronically unstable shoulders. Since this procedure is mainly performed in a young athletic population, the functional impact is significant. Published data does not shed light on the time needed to recover work-related or sports-related function. Performing this procedure arthroscopically may improve functional recovery. This led us to carry out a prospective, multicenter study to compare the functional recovery after arthroscopic versus open Latarjet procedure. Between June and November 2014, 184 patients were included in a prospective multicenter study: 85 in the open group and 99 in the arthroscopy group. The patients were evaluated preoperatively with the WOSI score. The early postoperative pain was evaluated on D3, D7 and D30. The WOSI score was determined postoperatively at 1, 3, 6 and 12 months of follow-up. The functional scores of the shoulder in both cohorts were identical overall preoperatively. In the immediate postoperative period, the arthroscopy group had statistically lower pain levels on D3 and D7. The postoperative WOSI was improved in both groups at 3 months, then continued to improve until it reached a plateau at 1 year. The WOSI score was better in the arthroscopy group at 3 months, but better in the open group at 6 months. This study found that a Latarjet procedure performed arthroscopically generates less immediately postoperative pain than when it is performed as an open procedure. The Latarjet procedure (whether open or arthroscopic) improves shoulder function, with normal function returning after 1 year. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Studies on the effect of a low intensity coordination exercise on the elderly with limited mobility are sparse. This prospective study attempted to compare the effectiveness of a customized coordination exercise and a strength exercise in improving the cognitive functioning and physical mobility on the elderly. Participants from two centers for the elderly were allocated to practice either an 8-week coordination training (CT) program or an 8-week towel exercise (TE) program. The Chinese Mini-Mental State Examination and Chinese Dementia Rating Scale (CDRS) were used to measure cognitive functioning of participants, and Timed Up-and-Go test for physical mobility. These assessments were administered before and after the program. Paired t-tests showed that the CDRS scores of the CT group improved significantly from 114.8 at pre-test to 119.3 after training (P = 0.045). The CDRS scores of the TE group also improved from 114.9 at pre-test to 116.9 after training. Findings from this prospective study demonstrated that low-intensity level mind-body exercise could be beneficial to the cognitive functioning of older adults.

    This report provides practical recommendations for the design and execution of multicenter functional MRI (MC-fMRI) studies based on the collective experience of the Function Biomedical Informatics Research Network (FBIRN). The study was inspired by many requests from the fMRI community to FBIRN group members for advice on how to conduct MC-fMRI studies. The introduction briefly discusses the advantages and complexities of MC-fMRI studies. Prerequisites for MC-fMRI studies are addressed before delving into the practical aspects of carefully and efficiently setting up a MC-fMRI study. Practical multisite aspects include: (i) establishing and verifying scan parameters including scanner types and magnetic fields, (ii) establishing and monitoring of a scanner quality program, (iii) developing task paradigms and scan session documentation, (iv) establishing clinical and scanner training to ensure consistency over time, (v) developing means for uploading, storing, and monitoring of imaging and other data, (vi) the use of a traveling fMRI expert, and (vii) collectively analyzing imaging data and disseminating results. We conclude that when MC-fMRI studies are organized well with careful attention to unification of hardware, software and procedural aspects, the process can be a highly effective means for accessing a desired participant demographics while accelerating scientific discovery.

    This study investigates functional status on Day 21 after dysvascular major lower limb amputation compared with one month pre-amputation and evaluates factors potentially influencing outcome. A prospective cohort study design was used. Data were collected via in-person interviews using structured instruments and covered functional level (Barthel index 100) one month pre-amputation and on Day 21. Out of a consecutive sample of patients having major lower limb amputation (tibia, knee or femoral) (n = 105), 51 participated on Day 21 follow-up. Clinical, demographic, body function and environmental data were analysed as factors potentially influencing outcome. From pre-amputation to Day 21, participants' functional level decreased significantly in all ten activities of daily living activities as measured by the Barthel Index. Almost 60% of participants were independent in bed-chair transfer on Day 21. Being independent in transfer on Day 21 was positively associated with younger age and attending physiotherapy after discharge. The findings indicate that short-term functional outcome is modifiable by quality of the postoperative care provided and thus highlights the need for increased focus on postoperative care to maintain basic function as well as establish and provide everyday rehabilitation in the general population of patients who have dysvascular lower limb amputations.

    Decompressive craniectomy has been revived as a radical surgical treatment in increased ICP. While the life saving effect is undisputable, reports about the functional outcome are controversial. Furthermore, there are no data comparing the outcome of craniectomised patients with different aetiologies. In a retrospective and prospective study we assessed the functional outcome of craniectomised patients (41 stroke and 24 traumatic brain injury (TBI) patients). The majority of patients considerably benefits from the rehabilitation process. Nevertheless, most of them remained dependent upon caregivers. In stroke patients there was a significant negative correlation between age and outcome. Even though TBI were younger than stroke patients there were no outcome differences between these groups. We found no correlation between the side of the hemisphere injured and outcome.

    Rehabilitation is widely advocated and provided as a standard of care for patients with total knee arthroplasty (TKA) but its effects on intermediate- to longer-term physical function is unclear. Also unknown is the relationship between the number of rehabilitation sessions attended and functional outcomes. We conducted a prospective cohort study of 1540 patients who had undergone TKA and were referred for rehabilitation. Physical function was indexed by the Short-Form 36 (SF-36) physical function score at 6 months post-TKA. We used multivariable linear regression to assess the association between rehabilitation attendance and Month-6 physical function. Among patients who attended rehabilitation, multivariable linear regression was used to examine the dose-response association between the number of sessions attended and Month-6 physical function. Of the 1540 patients, 68 patients did not attend rehabilitation, 86 patients attended one session, and 1386 patients attended two or more sessions. Adjusted for the propensity to attend rehabilitation, rehabilitation attendance was independently associated with better Month-6 SF-36 physical function (point estimate, 5.0 points; 95% CI, 0.5-9.5; P = 0.028 compared with patients with no rehabilitation). Among patients who attended rehabilitation, attending five sessions was associated with a 3.6-point increase in SF-36 scores (95% CI, 0.8-6.5; P = 0.01) relative to patients who attended one session. Rehabilitation attendance post-TKA is associated with an increase in self-report physical function. Among patients who attended rehabilitation, a modest dose-response relationship was observed between the number of sessions and functional outcomes.

    Recreational use of ecstasy (3,4-methylenedioxymethamphetamine [MDMA]) has been associated with memory impairments. Functional neuroimaging studies with cross-sectional designs reported altered memory-related hippocampal functioning in ecstasy-polydrug users. However, differences might be pre-existing or related to the concomitant use of amphetamine. To prospectively investigate the specific effects of ecstasy on memory-related hippocampal functioning. We used an associative memory task and functional magnetic resonance imaging (fMRI) in 40 ecstasy and/or amphetamine users at baseline (t1) and after 12 months (t2). At t1, all subjects had very limited amphetamine and/or ecstasy experience (less than 5 units lifetime dose). Based on the reported drug use at t2, subjects with continued ecstasy and/or amphetamine use (n = 17) were compared to subjects who stopped use after t1 (n = 12). Analysis of repeated measures revealed that encoding-related activity in the left parahippocampal gyrus changed differentially between the groups. Activity in this region increased in abstinent subjects from t1 to t2, however, decreased in subjects with continued use. Decreases within the left parahippocampal gyrus were associated with the use of ecstasy, but not amphetamine, during the follow-up period. However, there were no significant differences in memory performance. The current findings suggest specific effects of ecstasy use on memory-related hippocampal functioning. However, alternative explanations such as (sub-)acute cannabis effects are conceivable.

    OBJECT Current recommendations stress the need for cognitive parameters to be integrated in the evaluation of outcomes for intracranial meningioma surgery. The aim of this prospective study was to examine neurocognitive function in meningioma patients pre- and postoperatively. METHODS Patients with skull base (anterior and middle fossa) and convexity (anterior and posterior) meningiomas (n = 54) underwent neuropsychological examination prior to and 1 year after surgery. A control group (n = 52) of healthy volunteers matched for age, sex, and education underwent the same examination. Assessments included executive, memory, and motor functions with standardized testing. Patients with convexity meningiomas were clinically assessed for parietal association cortex functions. RESULTS All patients performed significantly worse (p < 0.05) in most neurocognitive domains than controls. The skull base group showed more disturbances in memory than the convexity group (p < 0.05). The anterior convexity group showed more deficits in executive function than the posterior convexity group, which presented with parietal association cortex deficits. Verbal deficits were more pronounced in the left hemisphere than in the right hemisphere. Patients with a large tumor (> 4 cm) had more severe neurocognitive deficits than those with a small tumor (< 4 cm). Postoperatively, patients showed no deterioration in neurocognitive function. Instead, significant improvement (p < 0.05) was observed in some executive, motor, and parietal association cortex functions. CONCLUSIONS According to the authors' findings, intracranial meningiomas may cause neurocognitive deficits in patients. Surgery does not cause a deterioration in cognitive function; instead, it may lead to improvements in some functions. Permanent neuropsychological postoperative deficits should be interpreted as tumor-induced rather than due to surgery.

    Objective: The objective was to assess functional outcome of rehabilitation in chronic severe traumatic brain injury (TBI) in-patients. Setting: The study was performed at university tertiary research hospital. Study Design: A prospective cross-sectional study Materials and Methods: Forty patients (34 men) with mean age of 30.1 years (range 6--60, SD 10.8), severe TBI (Glasgow coma scale 3--8, duration of coma > 6 hours, post-traumatic amnesia> 1 day postinjury) were admitted in rehabilitation unit minimum 3 months (mean 7.7±4.6 months, range 3--22 months) following injury falling in Glasgow outcome scale (GOS) of 3. Functional recovery was assessed using the Barthel Index (BI) score and disability rating scores (DRS). Data Analysis: Paired Student's t-test was used for the assessment of functional recovery using mean BI scores at admission and discharge. The Wilcoxon nonparametric test was used for the assessment of functional recovery by comparing admission and discharge DRS scores. Results: Mean duration of stay was 30.8 days (range 18--91, SD15.6). Significant functional recovery observed in patients comparing BI and DRS scores at admission and discharge (mean BI admission 50.5±25.4, range 0--85 vs. mean discharge BI score 61.1±25.3, range 0--95, P<0.001, mean DRS admission score 7.57±4.1, range 2.5--21.0 vs. mean discharge DRS score 6.36±4.3, range 1.0-21.0, P<0.001). Conclusion: Patients with severe TBI continue to show functional recovery even in chronic phase with rehabilitation. They are left with significant residual physical and cognitive deficits and would require long-term care and assistance from care givers for the daily activities, as suggested by the mean DRS score at discharge.

    To analyze mortality and functional outcome in patients with severe spontaneous intracerebral hemorrhage (ICH), and identify the clinical characteristics, radiological findings and therapeutic procedures predictive of mortality in the Intensive Care Unit (ICU) and during hospitalization, as well as of poor functional results at 6 months. A prospective, observational study was carried out. Neurocritical Care Unit of a university hospital. Patients diagnosed with ICH were included over a period of 23 months. Demographic characteristics, cardiovascular risk factors, regular medication, laboratory test parameters, cranial CT findings, therapeutic procedures and outcome data. None. A total of 186 patients with ICH met the inclusion criteria. Surgery to evacuate ICH was performed in 25.8% of the patients. The mortality rate was 46.7%. The modified Rankin score at 6 months was 5 (RI: 4.6). Multivariate Cox regression analysis showed the presence of diabetes, prior anticoagulation, as well as APACHE II severity and the type of bleeding on the cranial CT scan to be predictors of mortality and poor functional outcomes. On the other hand, neurosurgical procedures and intracranial pressure (ICP) monitoring were associated with better outcomes. The presence of comorbidities such as diabetes, or previous anticoagulation, as well as the CT findings were associated to poorer outcomes. In contrast, ICP monitoring and early neurosurgery were predictive of longer survival and better functional outcomes. Copyright © 2014 Elsevier España, S.L.U. and SEMICYUC. All rights reserved.

    Background Previous studies revealed that reduction of airway caliber in infancy might increase the risks for wheezing and asthma. However, the evidence for the predictive effects of pulmonary function on respiratory health in children was still inconsistent. Methods We conducted a population-based prospective cohort study among children in 14 Taiwanese communities. There were 3,160 children completed pulmonary function tests in 2007 and follow-up questionnaire in 2009. Poisson regression models were performed to estimate the effect of pulmonary function on the development of bronchitis and asthma. Results After adjustment for potential confounders, pulmonary function indices consistently showed protective effects on respiratory diseases in children. The incidence rate ratios of bronchitis and asthma were 0.86 (95% CI 0.79–0.95) and 0.91 (95% CI 0.82–0.99) for forced expiratory volume in 1 second (FEV1). Similar adverse effects of maximal mid-expiratory flow (MMEF) were also observed on bronchitis (RR = 0.73, 95% CI 0.67–0.81) and asthma (RR = 0.85, 95% CI 0.77–0.93). We found significant decreasing trends in categorized FEV1 (p for trend = 0.02) and categories of MMEF (p for trend = 0.01) for incident bronchitis. Significant modification effects of traffic-related air pollution were noted for FEV1 and MMEF on bronchitis and also for MMEF on asthma. Conclusions Children with high pulmonary function would have lower risks on the development of bronchitis and asthma. The protective effect of high pulmonary function would be modified by traffic-related air pollution exposure. PMID:22457716

    The aim of this study was to examine associations between a cognitive screen and four neuropsychologic tests administered at both 6 wks and 4 mos after amputation and five functional outcomes measured 12 mos after lower extremity amputation. This study includes a prospective cohort from four medical centers. Participants were primarily male Veterans experiencing their first lower extremity amputation as a result of complications of diabetes mellitus or peripheral arterial disease. Of those eligible, 87 (64%) enrolled; 75 (86%) were retained at 12 mos. Measures included demographic/health information, four neuropsychologic measures, the Locomotor Capability Index-5, the Gronigen Activity Restriction Scale, prosthetic use, community participation, and social integration. Better performance on the Short Portable Mental Status Questionnaire at 4 mos was associated with greater 12-mo mobility and social integration. Better attention and working memory abilities 6 wks after amputation were associated with increased 12-mo prosthetic wear; and at 4 mos after amputation, with greater 12-mo mobility. Better verbal memory at 6 wks was associated with greater 12-mo social integration and community participation as well as increased prosthetic wear. These findings highlight the potential value in including a brief, formal cognitive assessment in addition to a general mental status screen. Specific domains of cognitive function are differentially associated with functional outcomes and may inform amputation rehabilitation decisions.

    Data from the 1958 National Child Development Study (1958-2004) were used in a prospective study of the relation of financial adversity in childhood to lung function in midlife. It was hypothesized that such a relation would be found and would be mediated partly by early housing deprivation, partly by continuities in social disadvantage, and partly by smoking. These hypotheses were confirmed. The mediating variables explained nearly two-thirds of the observed relation. The strongest individual pathway from early financial hardship to adult lung function was through poor housing in childhood. Poor housing increased the risk of educational failure, which in turn was strongly related to less-advantaged social class. Lack of educational qualifications and less-advantaged social class independently increased the risk of higher levels of smoking. Mediating variables therefore acted in part as indicators of environmental exposures and in part through their links to adult smoking. Early financial adversity is associated with adult lung function partly through poor housing and partly through pathways involving continuities in social disadvantage and the associated environmental exposures and behaviors.

    Evaluation of surgery outcome measured by patient satisfaction or quality of life is very important, especially in plastic surgery. There is increasing interest in self-reporting outcomes evaluation in plastic surgery. The aim of our study was to determine patient satisfaction in regard to nose appearance and function with the use of a validated questionnaire, before and after rhinoplasty surgery. A prospective study was realized at a tertiary centre. All rhinoplasty surgeries performed in adults between February 2013 and August 2014 were included. Many patients underwent additional nasal surgery such as septoplasty or turbinoplasty. The surgical procedures and patients' characteristics were also recorded. Among 113 patients, 107 completed the questionnaires and the follow-up period. Analysis of pre-operative and post-operative Rhinoplasty Evaluation Outcome showed a significant improvement after 3 and 6 months in functional and aesthetic questions (p<0.01). In the pre-operative, patients anxious and insecure had a worse score (p<0.05). Difference in improvement of scores was not significant when groups were divided on basis of other nasal procedures, primary or revision surgery and open versus closed approach. We found that patients with lower literacy degree were more satisfied with the procedure. Rhinoplasty surgery significantly improved patient quality of life regarding nose function and appearance.

    There is inhomogeneous data about the hallucal extensor apparatus and the occurrence of accessory tendon slips and their function. We performed this study to clarify its anatomical features and make conclusions about its function. Investigations were performed prospectively during operative correction of severe hallux valgus and interphalangeus in 60 consecutive cases. The occurrence, topographic location and size of accessory extensor tendons as well as the insertion patterns were recorded. After dissection traction of the accessory tendon was carried out to gain information about its function. In contradiction to previous studies reporting numerous variations in the distal attachments of the hallucal extensor apparatus with different accessory tendons described, our investigations showed constant anatomical features. In all but one case (98.3%) there was an accessory medial extensor hallucis longus tendon adjacent to the main tendon, always inserting on the dorsomedial aspect of the metatarsophalangeal joint capsule. We therefore chose the terminology extensor hallucis capsularis (EHC) used in previous studies. The intraoperative testing of the tendon showed it to exert a pretension of the metatarsophalangeal (MTP) joint capsule. Our study showed consistent anatomical features with an occurrence of the EHC tendon in 98.3%. We determined that its function is to pretension the MTP joint capsule, therefore avoiding capsular impingement during hallucal extension. The high incidence of the EHC tendon in our study may also postulate a correlation with MTP joint deformities and further cadaveric studies will be necessary to evaluate a possible predisposition for hallux valgus genesis.

    To determine the effect of mode of delivery and perineal injury on sexual function at 6 and 12 months postpartum. Prospective cohort study. Tertiary women's hospital in Melbourne, Australia. A cohort of 440 primigravid women. The Female Sexual Function Index (FSFI) was completed at first visit (7-19 weeks of gestation), and at 6 and 12 months postpartum. A statistically significant difference in total FSFI or domain scores over time according to mode of delivery or perineal injury. In this cohort 54% of women had a normal vaginal delivery, 21% had an instrumental delivery, and 25% gave birth by caesarean section. No difference was found in total FSFI or domain scores according to mode of delivery over time between antenatal assessment and 12 months postpartum. Pain was decreased in the caesarean group only at 6 months postpartum. All groups showed pain scores at 12 months that were comparable with antenatal levels. For those who gave birth vaginally, 27% had an intact perineum, 50% had an episiotomy, and 6%, 14%, and 3% had first, second, and third-degree tears, respectively. The only differences between groups were found over time according to perineal injury at 6 months in the arousal domain. At 12 months, total FSFI and domain scores were no different to initial scores. At 12 months postpartum sexual function has returned to early pregnancy levels, irrespective of mode of delivery or perineal injury. © 2015 Royal College of Obstetricians and Gynaecologists.

    Previous studies in adults and animals with high level exposure to organic solvents suggested impairments in visual functioning. The objective of this pilot study was to examine the effects of maternal occupational exposure to organic solvents during pregnancy on offspring color vision and visual acuity, the development of which may be especially vulnerable to organic solvent exposure. We conducted a prospective cohort study of 32 offspring of women who were exposed occupationally to organic solvents during pregnancy compared with 27 nonexposed children. Monocular and binocular color vision and visual acuity were assessed using the Minimalist Test and the Cardiff Cards, respectively. Children with known hereditary color vision loss were excluded. Solvent-exposed children had significantly higher error scores on red-green and blue-yellow color discrimination, as well as poorer visual acuity compared with the control group. Exposure index (an estimated measure of exposure intensity) was not significantly related to color discrimination or visual acuity score. Despite excluding all children with a known family history of color vision loss, clinical red-green color vision loss was found among 3 of the 32 exposed children compared with none of the matched controls. These preliminary findings suggest that occupational exposure to organic solvents during pregnancy is associated with an increased risk of color vision and visual acuity impairment in offspring. The importance of routine visual function screening in risk assessment after prenatal exposure to chemicals warrants further attention. Copyright 2001 Wiley-Liss, Inc.

    Background. Previous retrospective studies have shown that physical functioning in older cancer survivors is affected after treatment, yet prospective data are lacking. The aim of this study was to assess change in physical functioning in different age groups of patients with hormone receptor-positive breast cancer who were enrolled in the Tamoxifen Exemestane Adjuvant Multinational (TEAM) phase III trial. Methods. Two physical parameters were assessed. Physical functioning was assessed using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire 1 year (T1) and 2 years (T2) after diagnosis. Physical activity was measured in metabolic equivalent of task (MET) hours/week at T1 and T2. Physical activity before diagnosis (T0) was assessed retrospectively at the T1 questionnaire. Patients were divided into three age groups: <60, 60–69, and ≥70 years. Decline in physical functioning was assessed using linear regression analysis. Differences in mean values of physical activity levels were calculated using repeated-measures one-way analysis of variance. Results. A total of 431 patients were included for analysis. In all age groups, physical activity levels at T1 and T2 were significantly lower than prediagnostic physical activity levels (T0) (p < .001 for all age groups). Age ≥70 years was independently associated with decline in physical functioning between T1 and T2 (β = −4.62, 95% confidence interval −8.73 to −0.51, p = .028). Conclusion. Patients aged 70 years or older treated with breast surgery and adjuvant hormonal therapy did not improve between years 1 and 2 after diagnosis to the same extent as did younger patients. Implications for Practice: Although older patients constitute a large share of the breast cancer population, little is known about the effect and consequences of treatment of breast cancer in this specific age group. This study revealed that, unlike younger patients, older patients do not regain

  7. Prospective study comparing laparoscopic and open adenomectomy: Surgical and functional results.

    PubMed

    Garcia-Segui, A; Angulo, J C

    Open adenomectomy (OA) is the surgery of choice for large volume benign prostatic hyperplasia, and laparoscopic adenomectomy (LA) represents a minimally invasive alternative. We present a long-term, prospective study comparing both techniques. The study consecutively included 199 patients with benign prostatic hyperplasia and prostate volumes>80g who were followed for more than 12 months. The patients underwent OA (n=97) or LA (n=102). We recorded and compared demographic and perioperative data, functional results and complications using a descriptive statistical analysis. The mean age was 69.2±7.7 years (range 42-87), and the mean prostate volume (measured by TRUS) was 112.1±32.7mL (range 78-260). There were no baseline differences among the groups in terms of age, ASA scale, prostate volume, PSA levels, Qmax, IPSS, QoL or treatments prior to the surgery. The surgical time (P<.0001) and catheter time (P<.0002) were longer in the LA group. Operative bleeding (P<.0001), transfusion rate (P=.0015) and mean stay (P<.0001) were significantly lower in the LA group. The LA group had a lower rate of complications (P=.04), but there were no significant differences between the groups in terms of major complications (Clavien score≥3) (P=.13) or in the rate of late complications (at one year) (P=.66). There were also no differences between the groups in the functional postoperative results: IPSS (P=.17), QoL (P=.3) and Qmax (P=.17). LA is a reasonable, safe and effective alternative that results in less bleeding, fewer transfusions, shorter hospital stays and lower morbidity than OA. LA has similar functional results to OA, at the expense of longer surgical times and longer catheter times. Copyright © 2016 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    2011-01-01

    Background There were few studies on the outcome of schizophrenia in developing countries. Whether the outcome is similar to or different from developed world is still a point for research. The main aim of the current study was to know if patients with early onset non affective psychosis can behave and function properly after few years from start of the illness or not. Other aims included investigation of possible predictors and associated factors with remission and outcome. Method The study prospectively investigated a group of 56 patients with onset of psychosis during childhood or adolescence. Diagnosis made according to DSM-IV criteria and included; schizophrenia, psychotic disorder not otherwise specified and acute psychosis. Severity of psychosis was measured by PANSS. Measures of the outcome included; remission criteria of Andreasen et al 2005, the children's global assessment scale and educational level. Results Analysis of data was done for only 37 patients. Thirty patients diagnosed as schizophrenia and 7 with Psychotic disorder not otherwise specified. Mean duration of follow up was 38.4 +/- 16.9 months. At the end of the study, 6 patients (16.2%) had one episode, 23(62.1%) had multiple episodes and 8 (21.6%) continuous course. Nineteen patients (51.4%) achieved full remission, and only 11(29.7%) achieved their average educational level for their age. Twenty seven percent of the sample had good outcome and 24.3% had poor outcome. Factors associated with non remission and poor outcome included gradual onset, low IQ, poor premorbid adjustment, negative symptoms at onset of the illness and poor adherence to drugs. Moreover, there was tendency of negative symptoms at illness start to predict poor outcome. Conclusion Some patients with early onset non affective psychosis can behave and function properly after few years from the start of the illness. Although remission is a difficult target in childhood psychosis, it is still achievable. PMID:21801438

This study aimed to examine changes in self-reported respiratory symptoms over 5 years, as well as to examine the lung function decline and determine whether it is within the expected range, to assess the dropout rate and reasons for leaving the profession, and to examine the associations between occupational factors and lung function changes at follow-up. Prospective study. Female hairdressing salons in Hebron city, Palestine. 170 female hairdressers who participated in a baseline survey in 2008 were followed up in 2013. A total of 161 participants participated in 2013. Change in reported respiratory symptoms and change in lung function over follow-up. Dropout from the profession and reasons for it. Differences between current and former hairdressers in respiratory symptoms and lung function at follow-up. Ambient air ammonia levels in 13 salons. Current hairdressers reported more respiratory symptoms in 2013 compared with baseline. Former hairdressers reported fewer symptoms at follow-up. At follow-up, current hairdressers showed a significant decrease in forced vital capacity of 35 mL/year (95% CI 26 to 44 mL/year) and of 31 mL/year (95% CI 25 to 36 mL/year) for forced expiratory volume in 1 s (FEV1). 28 (16%) of the hairdressers quit the job during the 5-year follow-up, 8 (28%) because of health problems. Hairdressers who had been working for 4 years or more at baseline showed a stronger decline in FEV1 compared with those who worked less than 4 years (difference 13, 95% CI 1 to 25). Current hairdressers developed more respiratory symptoms and larger lung function decline than former hairdressers during follow-up. Few hairdressers left their profession because of respiratory health problems. Working for more years is associated with lung function decline among current hairdressers.

    To determine if cochlear implantation has a delayed effect on the middle ear conductive hearing mechanism by measuring laser Doppler vibrometry (LDV) of the tympanic membrane (TM) in both implanted and contralateral control ears preoperatively and 3 months postoperatively, and then comparing the relative change in LDV outcome measures between implanted and control ears. Prospective cohort study. Eleven preoperative adult unilateral cochlear implant recipients in previously unoperated ears with normal anatomy and aerated temporal bones were included in this study. The magnitude and phase angle of umbo velocity transfer function in response to air- conduction (AC) stimulus, and the magnitude of umbo velocity in response to bone- conduction (BC) stimulus were measured in the implant ear and the contralateral control ear preoperatively and 3 months postoperatively and compared. No significant changes in the magnitude or phase angle of TM velocity in response to either AC or BC stimulus were observed in the implanted ear relative to the contralateral control ear 3 months following cochlear implantation. From the results of LDV measurements, it can be said that cochlear implantation has no significant delayed effect on the middle ear conductive mechanism. 4 Laryngoscope, 2017. © 2017 The American Laryngological, Rhinological and Otological Society, Inc.

    The purpose of this study was to evaluate the impact of mode of delivery on the sexual function of women using the Female Sexual Function Index (FSFI). This was a prospective study of 452 nulliparous women, comparing their sexual function before and after birth. A Turkish version of the FSFI questionnaire was administered within the first 8 weeks of pregnancy, at 3 and 6 months postpartum in a face-to-face manner and subsequently at the 12th month and 24th month over the telephone. Age, BMI, education level, house income, duration of marriage, birthweight, and feeding at each time point were similar between group 1 [vaginal birth and mediolateral episiotomy (MLE)] and group 2 [caesarean section (CS)]. In the postpartum period, there were 265 and 138 participants at 3rd month, 216 and 121 participants at 6th month, 189 and 111 participants at 12th month, and 133 and 85 participants at 24th month in group 1 and 2, respectively. The FSFI total scores decreased at 3 and 6 months postpartum in both groups (27.3 to 23.1 in group 1 and 27.5 to 25 in group 2; p < 0.05 for both). Desire, arousal, lubrication, satisfaction and pain scores were significantly decreased at 3 months postpartum in group (1) In group 1, desire, arousal and pain scores remained decreased at the 6th month compared to initial scores. Group 2 had significantly lower desire, lubrication, satisfaction and pain scores at 3 months postpartum compared to their initial scores. Decline in desire and lubrication domains persisted at the 6th month for group (2) None of the FSFI domain scores differed after 6th months when compared to pre-delivery scores in both groups. Compared with the caesarean group, the vaginal birth with MLE group had lower satisfaction and higher pain levels at 3 months postpartum (p < 0.0001, for both). None of the FSFI domains differed at the 6th, 12th or the 24th month between the groups. Our study revealed that caesarean section is not superior to vaginal birth in terms of

    To investigate the early pattern of longitudinal change in forced expiratory volume in 1 second (FEV1) among new Chinese coal miners, and the relation between coal mine dust exposure and the decline of lung function. The early pattern of lung function changes in 317 newly hired Chinese underground coal miners was compared to 132 referents. This three year prospective cohort study involved a pre-employment and 15 follow up health surveys, including a questionnaire and spirometry tests. Twice a month, total and respirable dust area sampling was done. The authors used a two stage analysis and a linear mixed effects model approach to analyse the longitudinal spirometry data, and to investigate the changes in FEV1 over time, controlling for age, height, pack years of smoking, mean respirable dust concentration, the room temperature during testing, and the groupxtime interaction terms. FEV1 change over time in new miners is non-linear. New miners experience initial rapid FEV1 declines, primarily during the first year of mining, little change during the second year, and partial recovery during the third year. Both linear and quadratic time trends in FEV1 change are highly significant. Smoking miners lost more FEV1 than non-smokers. Referents, all age less than 20 years, showed continued lung growth, whereas the miners who were under age 20 exhibited a decline in FEV1. Dust and smoking affect lung function in young, newly hired Chinese coal miners. FEV1 change over the first three years of employment is non-linear. The findings have implications for both methods and interpretation of medical screening in coal mining and other dusty work: during the first several years of employment more frequent testing may be desirable, and caution is required in interpreting early FEV1 declines.

    To estimate the association of improved nutrition in early life with adult intellectual functioning, controlling for years of schooling. Prospective cohort study. Four villages in Guatemala, as well as locations within Guatemala to which cohort members migrated. Individuals who had participated as children in a nutrition supplementation intervention trial from March 1, 1969, through February 28, 1977 (N = 2392). From May 1, 2002, through April 30, 2004, adequate information for analysis was obtained from 1448 of 2118 individuals (68.4%) not known to have died. Individuals exposed to atole (a protein-rich enhanced nutrition supplement) at birth through age 24 months were compared with those exposed to the supplement at other ages or to fresco, a sugar-sweetened beverage. We measured years of schooling by interview. Scores on the Serie Interamericana (InterAmerican Series) tests of reading comprehension and the Raven Progressive Matrices, obtained from May 1, 2002, through April 30, 2004. In models controlling for years of schooling and other predictors of intellectual functioning, exposure to atole at birth to age 24 months was associated with an increase of 3.46 points (95% confidence interval, -1.26 to 8.18) and 1.74 points (95% confidence interval, 0.53-2.95) on the InterAmerican Series and Raven Progressive Matrices tests, respectively. There was no statistical interaction between exposure to atole at birth to age 24 months and years of schooling on either outcome (P = .24 and P = .60, respectively). Improved early-life nutrition is associated with increased intellectual functioning in adulthood after taking into account the effect of schooling.

    Diverse structural, functional and valuable polysaccharides are synthesized by bacteria of all taxa and secreted into the external environment. These polysaccharides are referred to as exopolysaccharides and they may either be homopolymeric or heteropolymeric in composition and of diverse high molecular weights (10 to 1000 kDa). The material properties of exopolysaccharides have revolutionized the industrial and medical sectors due to their retinue of functional applications and prospects. These applications have been extensive in areas such as pharmacological, nutraceutical, functional food, cosmeceutical, herbicides and insecticides among others, while prospects includes uses as anticoagulant, antithrombotic, immunomodulation, anticancer and as bioflocculants. Due to the extensive applications of bacterial exopolysaccharides, this overview provides basic information on their physiologic and morphologic functions as well as their applications and prospects in the medical and industrial sectors.

Setting and population Community sample. Main outcome measure Participants were then assessed 3 times in young adulthood (ages 19, 21, and 24–26; 3215 observations of 1273 subjects) for adverse outcomes related to health, legal, financial, and social functioning. Results Participants with a childhood disorder had 6 times higher odds of at least one adverse adult outcome as compared to those with no history of psychiatric problems and 9 times higher odds of 2 or more such indicators (1 indicator: 59.5% vs. 19.9%, p <0.001; 2+ indicators: 34.2% vs. 5.6%, p <0.001). These associations persisted after statistically controlling for childhood psychosocial hardships and adult psychiatric problems. Risk was not limited to those with a diagnosis: participants with subthreshold psychiatric problems had 3 times higher odds of adult adverse outcomes and 5 time higher odds of 2 or more outcomes (1 indicator: 41.9% vs. 19.9%, p <0.001; 2+ indicators: 23.2% vs. 5.6%, p <0.001). The best diagnostic predictor of adverse outcomes was cumulative childhood exposure to psychiatric disorders. Conclusions Common, typically moderately-impairing, childhood psychiatric problems are associated with a disrupted transition to adulthood even if the problems do not persist into adulthood and even if the problems are subthreshold. Such problems provide potential target for public health efforts to ameliorate adult suffering and morbidity. PMID:26176785

    A prospective observational study was conducted to test the hypothesis that relative deprivation was associated with incident physical or cognitive disability, independent of absolute income. Study subjects consist of 9463 non-disabled people aged 65+ years in the Aichi Gerontological Evaluation Study (AGES), Aichi prefecture, Japan. Baseline mail-in survey in 2003 gathered information on income, educational attainment, lifestyle factors (smoking, alcohol consumption and health check-up) and healthcare utilisation. Three-year incidence of disability was assessed through public long-term care insurance databases and resident registry. A total of 7673 subjects (81%) with complete information were analysed. Our measure of relative deprivation was the Yitzhaki index across eight reference groups, which calculates the deprivation suffered by each individual as a function of the aggregate income shortfall for each person relative to everyone else with higher incomes in that person's reference group. Cox regression demonstrated that, after controlling for sociodemographic factors (including absolute income), the hazard ratio (and 95% confidence intervals) of incident physical/cognitive disability per one standard deviation increase in relative deprivation ranged from 1.13 (0.99 to 1.29) to 1.15 (1.01 to 1.31) in men and from 1.11 (0.94 to 1.31) to 1.18 (1.00 to 1.39) in women, depending on the definition of the reference group. Additional adjustment for lifestyle factors attenuated the hazard ratios to statistical non-significance. Relative deprivation may be a mechanism underlying the link between income inequality and disability in older age, at least among men. Lifestyle factors in part explain the association between relative deprivation and incident disability.

    Vitamin D, often deficient in kidney transplant (KTx) recipients, has potential immunomodulatory effects. This study aimed to evaluate whether vitamin D status affects the rate of decline in kidney allograft function. The study included a prospective cohort of 264 ambulatory KTx recipients at a single Japanese center. We measured the baseline 25-hydroxyvitamin D (25D) concentration and examined its association with annual decline in estimated glomerular filtration rate (eGFR). Secondary outcome was rescue treatment with iv methylprednisolone (IV-MP) as an index of rejection episodes. The mean serum 25D concentration was 17.1 (SD 6.5) ng/mL, and 68.4% patients had vitamin D inadequacy or deficiency. Time after KTx was a significant effect modifier for the association of serum 25D concentration with annual eGFR change and need for IV-MP (P for interaction < .1). We divided patients according to the median time after KTx (10 y) and found that low vitamin D was significantly associated with a rapid eGFR decline at less than 10 years after KTx but not at 10 or more years after KTx. The same was true for rescue treatment with IV-MP. Overall, propensity score matching showed independent associations of low vitamin D with both outcomes. Stratified matching confirmed pronounced associations at less than 10 years after KTx. Vitamin D deficiency predicts a rapid decline in eGFR and need for IV-MP at less than 10 years after KTx. Future studies are warranted to evaluate the clinical efficacy of vitamin D supplementation.

    This study examines the effect of Roux-en-Y gastric bypass (RYGB) and laparoscopic adjustable gastric banding (LAGB) on renal function for at least 5 years post-operatively in a tertiary referral center for bariatric surgery. This prospective cohort study of patients undergoing RYGB and LAGB measured renal function, blood pressure, and diabetes status pre-operatively and then 1 and 5 years post-operatively. Renal function was assessed using the Modification of Diet in Renal Disease (MDRD), Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), and Cockcroft-Gault formulae. Hypertension and diabetes were defined by the European Society of Hypertension and European Society of Cardiology joint guidelines and American Diabetes Association guidelines, respectively. A sub-group who had completed 10 years post-operative follow-up was also included. Estimated glomerular filtration rate (eGFR) increased over 5 years after RYGB (N = 190; 94 ± 2 mL/min/1.73 m(2) to 102 ± 22 mL/min/1.73 m(2), p = 0.01) and LAGB (N = 271; 88 ± 1 to 93 ± 22 mL/min/1.73 m(2), p = 0.02). In a sub-group with up to 10 years post-operative date, this trend was maintained. In patients with renal impairment, eGFR improved over 5 years (52 ± 2 to 68 ± 7 mL/min/1.73 m(2), p = 0.01). Remission of hypertension was greater after RYGB than LAGB at 1 year (32 vs. 16 %, p = 0.008) and at 5 years post-operatively (23 vs. 11 %, p = 0.02). Bariatric surgery stabilizes eGFR post-operatively for at least 5 years. In a sub-group with renal impairment, eGFR is increased in the first post-operative year and this is maintained for up to 5 years. RYGB is an effective procedure in achieving blood pressure control.

    Purpose: To determine the radiation dose-response relationship on salivary dysfunction and quality of life (QOL) over time in patients with lymphoma receiving radiation therapy (RT) to the head and neck (H and N). Methods and Materials: We conducted a prospective study on salivary-gland function in lymphoma patients receiving RT to the H and N. Fifteen patients were enrolled on the study. Dose-volume histograms and mean doses to the salivary glands were generated. Radiation-related toxicities and H and N-specific QOL were assessed before treatment and at prespecified time points posttreatment. Factors predicting a decrement in QOL were explored using Fisher's exact test. Results: During RT, 47% of patients experienced Grade >= 2 acute toxicity of the salivary gland, mucous membrane, or both. QOL scores improved over time, but up to one third of patients continued to have persistent oral symptoms at 2 years. At 6 months, a mean dose to at least one of the parotids of > 31 Gy was significantly associated with persistent dry mouth (100% vs. 17%, p = 0.02) and sticky saliva (100% vs. 25%, p = 0.04); a mean dose of > 11 Gy to the minor salivary glands was significantly associated with persistent sticky saliva (100% vs. 25%, p = 0.04), although the difference was no longer significant at 1 year. Conclusions: Limiting the mean parotid dose to <= 31 Gy and mean minor salivary gland dose to <= 11 Gy in lymphoma patients treated to the H and N may help reduce the risk of subacute xerostomia.

    Psychiatric problems are among the most common health problems of childhood. To test whether these health problems adversely affect adult functioning even if the problems themselves do not persist. Prospective, population-based study of 1420 participants from 11 predominantly rural counties of North Carolina who were assessed with structured interviews up to 6 times during childhood (9-16 years of age, for a total 6674 observations) for common psychiatric diagnoses and subthreshold psychiatric problems. The period for this study was from 1993 to 2010. A total of 1273 participants were assessed 3 times during young adulthood (19, 21, and 24-26 years of age, for a total of 3215 observations) for adverse outcomes related to health, the legal system, personal finances, and social functioning. Participants with a childhood disorder had 6 times higher odds (odds ratio [OR], 5.9 [95% CI, 3.6-9.7]) of at least 1 adverse adult outcome (ie, indicator) compared with those with no history of psychiatric problems and 9 times higher odds (OR, 8.7 [95% CI, 4.3-17.8]) of 2 or more such indicators (1 indicator: 59.5% vs 19.9% [P < .001]; ≥ 2 indicators: 34.2% vs 5.6% [P < .001]). These associations persisted after statistically controlling for childhood psychosocial hardships and adult psychiatric problems. Risk was not limited to those who received a diagnosis; participants with subthreshold psychiatric problems had 3 times higher odds (OR, 2.9 [95% CI, 1.8-4.8]) of adult adverse outcomes and 5 times higher odds (OR, 5.1 [95% CI, 2.4-10.7]) of 2 or more outcomes (1 indicator: 41.9% vs 19.9% [P < .001]; ≥ 2 indicators: 23.2% vs 5.6% [P < .001]). The best diagnostic predictor of adverse outcomes was cumulative childhood exposure to psychiatric disorders. Common, typically moderately impairing, childhood psychiatric problems are associated with a disrupted transition to adulthood even if the problems do not persist into adulthood and even if the problems are subthreshold

    To describe associations between tooth loss and changes in higher-level functional capacity. Prospective cohort study. Twenty-four Japanese municipalities between 2010 and 2013. Functionally independent community-dwelling persons aged 65 and older (N = 62,333). Self-reported number of teeth was used as an exposure variable. The outcome was changes in higher-level functional capacity measured using the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC), which consists of three domains: instrumental activities of daily living, intellectual activity, and social roles. The TMIG-IC score ranges from 0 (lowest function) to 13 (highest function). All covariates were chosen from baseline demographic, socioeconomic, health behavior, and health variables based upon evidence from previous studies. Inverse-probability weighting (IPW) with propensity score and multiple linear regression, estimating nonstandardized coefficients (β) and 95% confidence intervals (CIs), were used. The baseline response rate was 65.2%, and the follow-up rate was 70.1%. During the follow-up period, participants' TMIG-IC score declined by an average of 0.247 points (standard deviation: 1.446). The results showed a significant dose-response association between tooth loss and decline in higher-level functional capacity in multiple linear regression models. IPW models estimated the increment in TMIG-IC score (β = 0.170, 95% CI = 0.114 to 0.227) if edentulous participants gained 20 or more natural teeth. Tooth loss is associated with future decline in higher-level functional capacity. IPW models suggest that treatment for tooth loss attenuates decline in higher-level functional capacity. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    More than 50 percent of all infants born very preterm will experience significant motor and cognitive impairment. Provision of early intervention is dependent upon accurate, early identification of infants at risk of adverse outcomes. Magnetic resonance imaging at term equivalent age combined with General Movements assessment at 12 weeks corrected age is currently the most accurate method for early prediction of cerebral palsy at 12 months corrected age. To date no studies have compared the use of earlier magnetic resonance imaging combined with neuromotor and neurobehavioural assessments (at 30 weeks postmenstrual age) to predict later motor and neurodevelopmental outcomes including cerebral palsy (at 12-24 months corrected age). This study aims to investigate i) the relationship between earlier brain imaging and neuromotor/neurobehavioural assessments at 30 and 40 weeks postmenstrual age, and ii) their ability to predict motor and neurodevelopmental outcomes at 3 and 12 months corrected age. This prospective cohort study will recruit 80 preterm infants born ≤ 30 week's gestation and a reference group of 20 healthy term born infants from the Royal Brisbane & Women's Hospital in Brisbane, Australia. Infants will undergo brain magnetic resonance imaging at approximately 30 and 40 weeks postmenstrual age to develop our understanding of very early brain structure at 30 weeks and maturation that occurs between 30 and 40 weeks postmenstrual age. A combination of neurological (Hammersmith Neonatal Neurologic Examination), neuromotor (General Movements, Test of Infant Motor Performance), neurobehavioural (NICU Network Neurobehavioural Scale, Premie-Neuro) and visual assessments will be performed at 30 and 40 weeks postmenstrual age to improve our understanding of the relationship between brain structure and function. These data will be compared to motor assessments at 12 weeks corrected age and motor and neurodevelopmental outcomes at 12 months corrected age

    Running-related hamstring strain injuries remain a delicate issue in several sports such as soccer. Their unremittingly high incidence and recurrence rates indicate that the underlying risk has not yet been fully identified. Among other factors, the importance of neuromuscular coordination and the quality of interplay between the different hamstring muscle bellies is thought to be a key determinant within the intrinsic injury risk. Muscle functional magnetic resonance imaging (mfMRI) is one of the tools that has been proven to be valid for evaluating intermuscular coordination. To investigate the risk of sustaining an index or recurring soccer-related hamstring injury by exploring metabolic muscle characteristics using mfMRI. Cohort study; Level of evidence, 2. A total of 27 healthy male soccer players and 27 soccer players with a history of hamstring injuries underwent standardized mfMRI. The mfMRI protocol consisted of a resting scan, a strenuous bilateral eccentric hamstring exercise, and a postexercise scan. The exercise-related T2 change, or the signal intensity shift between both scans, was used to detect differences in metabolic characteristics between (1) the different hamstring muscle bellies and (2) the prospective cohorts based on the (re)occurrence of hamstring injuries during a follow-up period of 18 months. The risk of sustaining a first hamstring injury was associated with alterations in the intermuscular hierarchy in terms of the magnitude of the metabolic response after a heavy eccentric effort, with the dominant role of the semitendinosus set aside for a higher contribution of the biceps femoris (P = .017). Receiver operating characteristic (ROC) curve analysis demonstrated that this variable was significantly able to predict the occurrence of index injuries with a sensitivity of 100% and a specificity of 70% when the metabolic activity of the biceps femoris exceeded 10%. The risk of sustaining a reinjury was associated with a substantial deficit

    This study evaluated factors related to swallowing dysfunction after anterior cervical discectomy and fusion (ACDF) using videofluoroscopic swallowing studies (VFSS). Preoperative and postoperative VFSSs were done with 5 mL diluted barium. Oral transit time, pharyngeal delay time, pharyngeal response time (PRT), and pharyngeal transit time were measured. Hyoid bone movement and upper esophageal sphincter (UES) diameter were measured serially. Thickness of prevertebral soft tissue was measured from digitized VFSS images. In results, 12 of 20 patients showed abnormal postoperative VFSS findings. PRT decreased significantly after surgery. Hyoid bone movement did not change significantly after surgery. The maximal distance of UES opening decreased significantly after surgery, and the higher the level of surgery (C3 > C4 > C5 > C6), the greater the decrease in maximal distance of the UES opening after surgery. The time to widest opening of the UES was prolonged significantly. At the C3 and C4 levels, the change in prevertebral soft tissue thickness of patients with VFSS abnormalities was significantly greater than those without abnormalities. In conclusion, patients after ADCF with their highest surgery level at C3 and C4 showed more abnormal VFSS findings, significantly increased soft tissue thickness, and decreased maximal distance of UES opening. VFSS provided objective data related with swallowing dysfunction after ACDF. PMID:27822944

    Objective: To prospectively assess the surgical results from patients undergoing repairs to rotator cuff injuries via open and arthroscopic procedures, with regard to functional and clinical features, and by means of ultrasound examinations, and to compare occurrences of renewed tearing. Methods: Sixty patients underwent operations performed by the same surgeon (29 via open surgery and 31 via arthroscopy), to repair complete rotator cuff tears. The procedures were performed at Hospital Governor Israel Pinheiro (HGIP) and Mater Dei Hospital in Belo Horizonte, Minas Gerais, between August 2007 and February 2009. The patients were assessed functionally by means of the UCLA score before and after the operation, and magnetic resonance imaging was done before the operation. All the patients were reassessed at least 12 months after the operation, and an ultrasound examination was also performed at this time. Results: Out of the 29 patients who underwent open surgery, 27 (93.1%) presented good or excellent results, with a mean UCLA score of 32 after the operation. Their mean follow-up was 14 months. Three patients presented renewed tearing on ultrasound, of whom one remained asymptomatic. Out of the 31 patients who underwent arthroscopic procedures, 29 (93.5%) presented good or excellent results, with a mean UCLA score of 33 after the operation. Their mean follow-up was 19 months. Two patients presented renewed tearing, of whom one remained asymptomatic and one evolved with loosening of an anchor, with an unsatisfactory result. Conclusion: The repairs on rotator cuff injuries presented good results by means of both open surgery and arthroscopy, with similar functional results in the two groups and similar rates of renewed tearing.

    To prospectively evaluate the effect of transrectal ultrasonography (TRUS)-guided prostate biopsy on erectile and voiding function at multiple time-points after biopsy. All men who underwent TRUS-guided prostate biopsy completed a five-item version of the International Index of Erectile Function (IIEF-5) and the International Prostate Symptom Score (IPSS) before and at 1, 4 and 12 weeks after TRUS-guided biopsy. Statistical analyses used were a general descriptive analysis, continuous variables using a t-test and categorical data using chi-square analysis. A paired t-test was used to compare each patient's baseline score to their own follow-up survey scores. In all, 220 patients were enrolled with a mean age of 64.1 years and PSA level of 6.7 ng/dL. At initial presentation, 38.6% reported no erectile dysfunction (ED), 22.3% mild ED, 15.5% mild-to-moderate ED, 10% moderate ED, and 13.6% severe ED. On paired t-test there was a statistically significant reduction in IIEF-5 score at 1 week after biopsy compared with before biopsy (18.2 vs 15.5; P < 0.001). This remained significantly reduced at 4 (18.4 vs 17.3; P = 0.008) and 12 weeks (18.4 vs 16.9, P = 0.004) after biopsy. The effects of TRUS-guided prostate biopsy on erectile function have probably been underestimated. It is important to be aware of these transient effects so patients can be appropriately counselled. The exact cause of this effect is yet to be determined. © 2014 The Authors BJU International © 2014 BJU International Published by John Wiley & Sons Ltd.

    To describe the characteristics of a cohort of patients with microscopic colitis (MC; lymphocytic (LC) or collagenous (CC) colitis) and to compare them with patients with functional bowel disorder with diarrhea (FBD-D). Between September 2010 and June 2012, patients fulfilling the following inclusion criteria were prospectively included in 26 centers in France: (i) having at least three bowel movements daily with change in stool consistency; (ii) duration of abnormal bowel habit >4 weeks; and (iii) normal or near-normal colonoscopy. Each patient underwent a colonoscopy and colonic biopsies. We compared the demographic, clinical, biological, and etiological characteristic of patients with MC (CC and LC) with those of control patients with FBD-D. A total of 433 patients were included: 129 with MC (87 LC and 42 CC), 23 with another organic disease, and 278 with FDB-D, including patients with diarrhea and abdominal pain who met the criteria of Rome III (irritable bowel syndrome with diarrhea) and patients with functional diarrhea without abdominal pain. Logistic regression analysis identified the following independent predictors of MC: age >50 years (odds ratio (OR)=3.1, 95% confidence interval (CI)=1.6-5.9), presence of nocturnal stools (OR=2, 95% CI=1.1-3.9), weight loss (OR=2.5, 95% CI=1.3-4.7), duration of diarrhea <12 months (OR=2.0, 95% CI=1.1-3.5), recent introduction of new drugs (OR=3.7, 95% CI=2.1-6.6; P<0.0001), and the presence of a known autoimmune disorder (OR=5.5, 95% CI=2.5-12). Age >50 years, the presence of nocturnal stools, weight loss, the introduction of a new drug, and the presence of a known autoimmune disease increase the probability of MC and thus the indication for colonoscopy with biopsies.

    Breast cancer (BC) and/or its treatments may affect sexual functioning based on physiological and psychosocial mechanisms. The aim of this study was to prospectively investigate sexual adjustment of BC patients during a follow-up period of one year after mastectomy (ME) or breast conserving therapy (BCT). In this prospective controlled study, women with BC and an age-matched control group of healthy women completed the Beck Depression Inventory Scale, World Health Organization 5 Well-being scale, Body Image Scale, EORTC QLQ questionnaire, Dyadic Adjustment Scale, Short Sexual Functioning Scale and Specific Sexual Problems Questionnaire to assess various aspects of sexual and psychosocial functioning before surgery, six months and one year after surgical treatment. In total, 149 women with BC and 149 age-matched healthy controls completed the survey. Compared to the situation before surgery, significantly more BCT women reported problems with sexual arousal six months after surgery and significantly more women of the ME group reported problems with sexual desire, arousal and the ability to achieve an orgasm six months and one year after surgery. While in comparison with healthy controls, no significant differences in sexual functioning were found after BCT surgery, significantly more women who underwent ME reported problems with sexual desire, arousal, the ability to achieve an orgasm and intensity of the orgasm. Although little differences were seen in sexual functioning in the BCT group during prospective analyses and in comparison with healthy controls, analyses revealed that women who underwent a ME were at risk for post-operative sexual dysfunctions.

    Objectives Farming as an occupation is considered a risk factor for asthma and reduced lung function. By contrast, living on a farm during infancy has been reported to be associated with lower risk of asthma in adulthood. However, little is known about the association between farming environment during infancy and lung function in adulthood. We aimed to study the prospective longitudinal association between farming environment during infancy and lung function in adulthood. Design A prospective birth cohort study. Setting Northern Finland. Participants 5666 participants born in 1966 were followed up at the age of 31 years. Primary outcome measures Spirometry at the age of 31 years. Results To be born into a farmer’s family was associated with higher forced expiratory volume in 1 s (FEV1) (36 mL; 95% CI 6 to 67 mL) and forced vital capacity (FVC) (40 mL; 95% CI 5 to 75 mL) at the age of 31 years. Contact with farm animals during infancy was associated with higher FEV1. No associations were seen with FEV1/FVC (FEV1/FVC ratio). Having dogs in childhood revealed similar associations. There was a suggestive dose-dependent association with the number of animal species during childhood and higher FEV1 and FVC at adulthood, especially among women. Conclusions Farming environment in early life may have a positive impact on lung function in adulthood. PMID:26201721

    Abstract The best method of preventing hypoparathyroidism after thyroidectomy is to keep parathyroid glands in situ. However, hypoparathyroidism still regularly occurs with the existing parathyroid classification system, and the incidence of permanent hypoparathyroidism has not been reduced. We created a novel system for classifying parathyroid glands that can guide parathyroid preservation in thyroidectomy. We prospectively observed parathyroid glands using the new system in 218 neck surgeries, compared with 132 under the traditional system from January 2014 to September 2015 at a single clinic center. Briefly, we classified parathyroid glands as follows: Type A, no dependency on the thyroid; B1, partial blood supply from the thyroid but retains adequate blood supply after removal of the thyroid; B2, partial blood supply from the thyroid and becomes devascularized after the removal of the thyroid; B3, blood supply mostly from the thyroid; and C, blood supply completely dependent on the thyroid. The classifications were used to decide between in situ preservation or auto-transplantation. The most common type of parathyroid gland was type B1 (53.77%), followed by type A (20.89%), which are the perfect categories for in situ preservation. Type B2 (17.52%) and type B3 (1.21%) have a chance to be kept in situ. For type C (6.61%), in situ preservation is impossible. When in-situ preservation is ruled out, parathyroid auto-transplantation is an alternative, with partial or total gland tissue, depending on the classification and the surgeon's discretion. Among the patients who were classified under the new system, 43.6% presented with transient hypoparathyroidism (symptoms lasting ≤6 months) after surgery, versus 42.4% in the old system, which was not a significant difference. However, permanent hypothyroidism (symptoms lasting >6 months) was not detected in the applied group, but in 3.0% of patients in the nonapplied group (P = 0.01). Our novel functional

In this study, we test the hypothesis that physical activity earlier in the life course preserves high physical function over an extended period of time, before the onset of major age-related declines in physical function. A cohort study with an average of 8.8 years of follow-up (1991-1993 to 2001). Logistic regression analyses were conducted adjusting for long-standing illness, baseline physical function, smoking, body mass index, and employment grade. Participants were 6398 London-based civil servants aged 39 to 63 years at baseline, 90% of whom were working. The main outcome measure was physical function measured by the Short Form (SF-36) General Health Survey. Relatively fit and healthy, mainly working, middle-aged men and women who were physically active at recommended levels, were more likely to report high physical function at follow-up, compared to their sedentary counterparts (odds ratio 1.63, 95% confidence interval 1.32-2.00). The association between initial level of physical activity and high physical function at follow-up remained after adjustment for baseline level of physical function and the presence of long-standing illness. Participation in a physically active lifestyle during mid-life appears to be critical to the maintenance of high physical function in those who are fit and well enough to work and do or do not report any long-standing illness.

    Bariatric surgery provides long-term weight loss and improvement of obesity-associated diseases such as nonalcoholic steatohepatitis (NASH). Histologic improvement of NASH has been reported in some studies after bariatric surgery. This study was designed to assess the liver function in obese patients as well as its recovery after bariatric surgery with a noninvasive test method. In a prospective cohort study from October 2011 to May 2014, morbidly obese individuals receiving bariatric surgery were investigated for functional liver recovery (n = 34). Liver function was determined by the LiMAx test (enzymatic capacity of cytochrome P450 1A2) preoperatively, 6 and 12 months postoperatively. Liver biopsy specimens were obtained from 18 participants and classified according to the nonalcoholic fatty liver disease (NAFLD) activity score (NAS). The mean age of participants was 44 years, and the mean body mass index (BMI) was 52 kg/m(2). The mean percent excess BMI loss (%EBMIL) was 53 % after 6 months and 68 % after 1 year. Mean liver function capacity increased significantly from 255 μg/kg/h preoperative to 324 μg/kg/h after 6 months and 342 μg/kg/h after 12 months. A negative correlation was observed between %EBMIL and alteration of liver function capacity in the first 6 months. Finally, the median NAS showed a negative correlation with liver function capacity. Bariatric surgery leads to a significant functional recovery of the liver. An initial marked weight loss may negatively influence functional liver recovery.

    The effect of breastfeeding on cognitive abilities is examined in the offspring of highly educated women and compared to the effects in women with low or middle educational attainment. All offspring consisted of 12-year old mono- or dizygotic twins and this made it possible to study the effect of breastfeeding on mean cognition scores as well as the moderating effects of breastfeeding on the heritability of variation in cognition. Information on breastfeeding and cognitive ability was available for 6,569 children. Breastfeeding status was prospectively assessed in the first years after birth of the children. Maternal education is positively associated with performance on a standardized test for cognitive ability in offspring. A significant effect of breastfeeding on cognition was also observed. The effect was similar for offspring with mothers with a high, middle, and low educational level. Breast-fed children of highly educated mothers score on average 7.6 point higher on a standardized test of cognitive abilities (CITO test; range 500–550; effects size = .936) than formula-fed children of mothers with a low education. Individual differences in cognition scores are largely accounted for by additive genetic factors (80%) and breastfeeding does not modify the effect of genetic factors in any of the three strata of maternal education. Heritability was slightly lower in children with a mother with a middle-level education.

    Chronic kidney disease is a risk factor for cognitive impairment. Albuminuria is an early manifestation of chronic kidney disease and a marker of endothelial dysfunction and vascular risk. Results of prior studies of albuminuria and cognitive function are contradictory. The authors studied 1,345 community-dwelling women and men in southern California (mean age, 75 years) at a 1992–1996 research clinic visit, when urine albumin/creatinine ratio (ACR) was measured in spot morning urine and cognitive function was evaluated by using the Mini-Mental State Examination Trail-Making Test B, and category fluency test. An ACR of ≥30 mg/g was found in 17% of women and 15% of men in 1992–1996. Analysis of covariance was used to compare cognitive function score by categorical ACR. Between 1999 and 2002, 759 participants returned for repeat cognitive function testing. For men, but not women, baseline albuminuria, but not estimated glomerular filtration rate, was associated with reduced cognitive function at follow-up on all tests (P's < 0.05). An ACR of ≥30 mg/g was associated with greater annual decline in Mini-Mental State Examination and category fluency scores. Albuminuria may be an easily measured marker predicting future cognitive function decline. Results imply a common underlying mechanism affecting the renal and cerebral microvasculature.

    Past research on the role of cognitive performance in predicting later psychosocial functioning for individuals with first treated episode of a psychotic disorder has yielded inconsistent results. Several factors have been suggested as determining the strength of any such relationship including the type of functioning measured, time of the cognitive assessment, covariates included and the use of global versus specific measures of cognitive functioning. In the current study, we examined the importance of these factors in a five year prospective study of individuals with first episode psychotic disorders. Just over 80% of the sample had a schizophrenia spectrum disorder. Cognitive assessments were carried out after initiation of treatment on 113 patients, and at one year for 79 patients. There was evidence that cognition predicted occupational functioning and use of a disability pension, but not a summary index of functioning or use of supervised housing, at follow-up. Overall I.Q. was a more consistent predictor than measures of specific cognitive functions, and there was evidence that cognition assessed after presentation for treatment, particularly after a year of treatment, was more predictive of later functioning than premorbid I.Q. Cognitive functioning, however, did not add to the prediction of outcomes beyond the level possible using past educational achievement or academic premorbid adjustment.

    The aim of the present study was to explore variations in functioning and disability--with regard to cognition, manual dexterity, walking, energy, mood, activities of daily living and social/ lifestyle activities--every six months during a 2-year period, in 200 people with MS (PwMS) at an outpatient MS specialist clinic. Symbol Digit Modalities Test, Nine Hole Peg Test, Timed 25 Foot Walk, Fatigue Severity Scale, Beck Depression Inventory, Katz ADL Index Extended and Frenchay Activities Index were used to collect data. For analyses of statistically significant changes in scores during the study period, repeated measures ANOVA was used for ratio data and Friedman ANOVA for ordinal data. In addition, effect size as well as the mean/median change in score during the study period were determined for each functioning. Nearly all functioning studied varied significantly but there was no general deterioration in the sample. Small effect sizes were mainly found for the Frenchay Activities Index and a plausible practice effect was detected for the Symbol Digit Modalities Test. As many as 63% with regard to walking and 46% with regard to manual dexterity demonstrated >20% mean change in scores which has proved to be a reliable and clinically meaningful change. This study illustrates the importance of systematic and regular multidimensional assessment of functioning and disability in PwMS aiming to identify disabilities that could be minimized through timely and appropriate evidence-based interventions. The fluctuation in functioning and the conceivable learning effect inherent in instruments used should be taken into consideration when designing studies and interpreting the results.

    Background Numerous cross-sectional studies have reported reduced lung function among welders but limitations of exposure assessment and design preclude causal inference. The aim of this study was to investigate if long-term exposure to welding fume particulates accelerates the age-related decline in lung function. Methods Lung function was measured by spirometry in 1987 and 2004 among 68 steel welders and 32 non-welding production workers. The decline in forced expiratory volume (FEV1) was analysed in relation to cumulated exposure to fume particulates among welders during the follow-up period. Results Among smokers the decline in FEV1 through follow-up period was in average 150 ml larger among welders than non-welders while the difference was negligible among non-smokers. The results did not reach statistical significance and within welders the decline in lung function was not related to the cumulated welding particulate exposure during follow-up period Conclusion Long-term exposure to welding emissions may accelerate the age-related decline of lung function but at exposure levels in the range of 1.5 to 6.5 mg/m3 the average annual excess loss of FEV1 is unlikely to exceed 25 ml in smokers and 10 ml in non-smokers.

    Abnormal liver function test is sometimes seen in hyperthyroidism but no study had been carried out to compare liver function test in the hyperthyroid state and the euthyroid state. This study aimed to find the prevalence of abnormal liver function test in Graves' disease and compare liver function test result in the hyperthyroid state with the euthyroid state. This is a prospective study of 112 patients who had Graves' disease. These patients were new cases or recurrent cases of Graves' disease whose medication had been discontinue for more than 3 months. We followed-up 86 patients received treatment with antithyroid drugs up to the euthyroid state and compared liver function test at diagnosis and in the euthyroid state. An abnormal level of serum globulin was the most abnormal liver function test results in Graves' disease at 30.4%, followed by an abnormal level of serum alkaline phosphatase of 25.0% and gamma-glutamyl transpeptidase (GGT) of 23.3%. The trend of GGT levels returned to normal but there was an increased in serum alkaline phosphatase after treatment until the euthyroid state in the follow-up group. Abnormal liver function tests in Graves' disease are common, after treatment until the euthyroid state, experienced an improvement in GGT level but also an increase in serum alkaline phosphatase level.

Furthermore, to compare prevalence of urinary incontinence (UI) and pelvic organ prolapse (POP) in the two groups at the same assessment points. This is a prospective cohort study following 300 nulliparous pregnant women giving birth at a public university hospital. VRP, PFM strength, and endurance were measured with vaginal manometry. ICIQ-UI-SF questionnaire and POP-Q were used to assess UI and POP. Diastasis recti abdominis was diagnosed with palpation of  ≥2 fingerbreadths 4.5 cm above, at, or 4.5 cm below the umbilicus. At gestational week 21 women with diastasis recti abdominis had statistically significant greater VRP (mean difference 3.06 cm H2 O [95%CI: 0.70; 5.42]), PFM strength (mean difference 5.09 cm H2 O [95%CI: 0.76; 9.42]) and PFM muscle endurance (mean difference 47.08 cm H2 O sec [95%CI: 15.18; 78.99]) than women with no diastasis. There were no statistically significant differences between women with and without diastasis in any PFM variables at 6 weeks, 6 months, and 12 months postpartum. No significant difference was found in prevalence of UI in women with and without diastasis at any assessment points. Six weeks postpartum 15.9% of women without diastasis had POP versus 4.1% in the group with diastasis (P = 0.001). Women with diastasis were not more likely to have weaker PFM or more UI or POP.

    Background The neuropsychological consequences of exposure to environmental hypobaric hypoxia (EHH) remain unclear. We thus investigated them in a large group of healthy volunteers who trekked to Mount Everest base camp (5,300 m). Methods A neuropsychological (NP) test battery assessing memory, language, attention, and executive function was administered to 198 participants (age 44.5±13.7 years; 60% male). These were studied at baseline (sea level), 3,500 m (Namche Bazaar), 5,300 m (Everest Base Camp) and on return to 1,300 m (Kathmandu) (attrition rate 23.7%). A comparable control group (n = 25; age 44.5±14.1 years; 60% male) for comparison with trekkers was tested at/or near sea level over an equivalent timeframe so as to account for learning effects associated with repeat testing. The Reliable Change Index (RCI) was used to calculate changes in cognition and neuropsychological function during and after exposure to EHH relative to controls. Results Overall, attention, verbal ability and executive function declined in those exposed to EHH when the performance of the control group was taken into account (RCI .05 to -.95) with decline persisting at descent. Memory and psychomotor function showed decline at highest ascent only (RCI -.08 to -.56). However, there was inter-individual variability in response: whilst NP performance declined in most, this improved in some trekkers. Cognitive decline was greater amongst older people (r = .42; p < .0001), but was otherwise not consistently associated with socio-demographic, mood, or physiological variables. Conclusions After correcting for learning effects, attention, verbal abilities and executive functioning declined with exposure to EHH. There was considerable individual variability in the response of brain function to sustained hypoxia with some participants not showing any effects of hypoxia. This might have implications for those facing sustained hypoxia as a result of any disease. PMID:28346535

    Most ovarian cysts in women of reproductive age are physiological (functional) and patients have been treated for years with oral contraceptives to obtain the resolution of these cysts. Expectant management has been suggested to have the same effectiveness as hormonal treatment but such suggestions come from studies including all kinds of cysts. The objective of the present study was to assess the resolution of functional ovarian cysts, observed after ovulation induction, with expectant management and hormonal treatment and also to determine the period of time necessary for the resolution of the cysts. For this purpose, 53 patients with ovarian cysts, observed by transvaginal ultrasound within the first 5 days of a cycle after ovulation induction, were randomized to have expectant management (group A) or to receive oral contraception (group B) for one cycle. If the cyst persisted, the patient was followed for another cycle, without any treatment. Within the 50 women who completed the trial, a complete resolution of the cysts was observed in 19/25 (76%) and 18/25 (72%) in groups A and B respectively. On the other hand, all the persistent cysts disappeared after a second cycle without any treatment. In conclusion, expectant management is as effective as oral contraceptives for the resolution of functional ovarian cysts induced by ovarian stimulation. However, studies with a larger number of cases are needed to increase the power of the results and to obtain a firm conclusion.

    Complaints of a dry mouth (xerostomia) and sialoadenitis are frequent side effects of radioiodine treatment in differentiated thyroid cancer (DTC) patients. However, detailed prospective data on alterations in salivary gland functioning after radioiodine treatment ((131)I) are scarce. Therefore, the primary aim of this study was to prospectively assess the effect of high-activity radioiodine treatment on stimulated whole saliva flow rate. Secondary aims were to study unstimulated whole and stimulated glandular (i.e., parotid and submandibular) saliva flow rate and composition alterations, development of xerostomia, characteristics of patients at risk for salivary gland dysfunction, and whether radioiodine uptake in salivary glands on diagnostic scans correlates to flow rate alterations. In a multicenter prospective study, whole and glandular saliva were collected both before and 5 mo after radioiodine treatment. Furthermore, patients completed the validated xerostomia inventory. Alterations in salivary flow rate, composition, and xerostomia inventory score were analyzed. Salivary gland radioiodine uptake on diagnostic scans was correlated with saliva flow rate changes after radioiodine treatment. Sixty-seven patients (mean age ± SD, 48 ± 17 y; 63% women, 84% underwent ablation therapy) completed both study visits. Stimulated whole saliva flow rate decreased after ablation therapy (from 0.92 [interquartile range, 0.74-1.25] to 0.80 [interquartile range, 0.58-1.18] mL/min, P = 0.003), as well as unstimulated whole- and stimulated glandular flow rates (P < 0.05). The concentration of salivary electrolytes was similar at both study visits, whereas the output of proteins, especially amylase (P < 0.05), was decreased. The subjective feeling of dry mouth increased (P = 0.001). Alterations in saliva flow rate were not associated with semiquantitatively assessed radioiodine uptake in salivary glands on diagnostic scans. For the small cohort of patients undergoing repeated

    To compare the sleep patterns, mood states, and cognitive functioning of primiparous mothers during the first 3 weeks postpartum with those of a control group of nonpostpartum women and to assess the relationships among these variables. For the first 3 weeks postpartum, 30 primiparous women and 28 nonpostpartum mothers completed daily assessments of mood and recorded multiple aspects of sleep including time of retiring, occurrence and duration of sleep interruption, time of awakening, and morning alertness. Objective measures of memory, attention/concentration, and psychomotor performance were obtained on three occasions. Postpartum women reported more evening awakenings, more time awake after retiring, and more naps than controls, but overall sleep time was similar. New mothers experienced a higher level of dysphoric mood during the first week than nonpostpartum controls; however, controlling for the effect for "time awake" at night eliminated the significant effect for dysphoric mood. Few differences were observed on the multiple assessments of cognitive function; however, performances of new mothers on memory and psychomotor tasks were likely to be influenced by sleep loss. Women must make important adjustments in their sleep patterns during the postpartum period. In the study group, these adjustments were largely successful, particularly after the first week postpartum, in avoiding the negative consequences of sleep disturbances such as dysphoric mood and impaired cognitive function. Nevertheless, the significant associations between sleep indices and mood and objective measures of cognitive function point to the importance of encouraging appropriate amounts of sleep for recently delivered women.

    Objective Previous studies have reported that elderly victims of natural disasters might be prone to a subsequent decline in motor function. Victims of the Great East Japan Earthquake (GEJE) relocated to a wide range of different types of housing. As the evacuee lifestyle varies according to the type of housing available to them, their degree of motor function loss might also vary accordingly. However, the association between postdisaster housing type and loss of motor function has never been investigated. The present study was conducted to investigate the association between housing type after the GEJE and loss of motor function in elderly victims. Methods We conducted a prospective observational study of 478 Japanese individuals aged ≥65 years living in Miyagi Prefecture, one of the areas most significantly affected by the GEJE. Information on housing type after the GEJE, motor function as assessed by the Kihon checklist and other lifestyle factors was collected by interview and questionnaire in 2012. Information on motor function was then collected 1 year later. The multiple logistic regression model was used to estimate the multivariate adjusted ORs of motor function loss. Results We classified 53 (11.1%) of the respondents as having loss of motor function. The multivariate adjusted OR (with 95% CI) for loss of motor function among participants who were living in privately rented temporary housing/rental housing was 2.62 (1.10 to 6.24) compared to those who had remained in the same housing as that before the GEJE, and this increase was statistically significant. Conclusions The proportion of individuals with loss of motor function was higher among persons who had relocated to privately rented temporary housing/rental housing after the GEJE. This result may reflect the influence of a move to a living environment where few acquaintances are located (lack of social capital). PMID:27810976

    Recent increases in numbers of older people have been accompanied by increases in those with functional disability. No study has examined the association between community social capital and the onset of functional disability. The association between community social capital and the onset of functional disability was examined using data from the Aichi Gerontological Evaluation Study, a prospective cohort established in 2003 in Japan. Perceptions of community social capital (indicators of social cohesion such as trust of others and extent of social participation) in 6953 men and 7636 women aged 65 years or older were surveyed. Multilevel survival analysis using the discrete-time hazard model was applied. During 4-year follow-up, onset of functional disability occurred in 759 men and 1146 women. Women living in communities with higher mistrust had 1.68 (95% CI 1.14 to 2.49) times higher OR of onset of disability, even after adjusting for covariates. Mediators did not substantially change this association. Lack of social participation seemed to affect the health of women, though the effect was marginal (OR for covariates adjusted model =1.12 (95% CI 0.96 to 1.31)). There were no significant ORs among men. Lower community social capital was associated with higher incidence of onset of functional disability among older women but not among men. Community-based interventions to promote social capital may be useful for preventing functional disability of older Japanese women.

    Exposure to arsenic through drinking water has been linked to respiratory symptoms, obstructive lung diseases, and mortality from respiratory diseases. Limited evidence for the deleterious effects on lung function exists among individuals exposed to a high dose of arsenic. To determine the deleterious effects on lung function that exist among individuals exposed to a high dose of arsenic. In 950 individuals who presented with any respiratory symptom among a population-based cohort of 20,033 adults, we evaluated the association between arsenic exposure, measured by well water and urinary arsenic concentrations measured at baseline, and post-bronchodilator-administered pulmonary function assessed during follow-up. For every one SD increase in baseline water arsenic exposure, we observed a lower level of FEV1 (-46.5 ml; P < 0.0005) and FVC (-53.1 ml; P < 0.01) in regression models adjusted for age, sex, body mass index, smoking, socioeconomic status, betel nut use, and arsenical skin lesions status. Similar inverse relationships were observed between baseline urinary arsenic and FEV1 (-48.3 ml; P < 0.005) and FVC (-55.2 ml; P < 0.01) in adjusted models. Our analyses also demonstrated a dose-related decrease in lung function with increasing levels of baseline water and urinary arsenic. This association remained significant in never-smokers and individuals without skin lesions, and was stronger in male smokers. Among male smokers and individuals with skin lesions, every one SD increase in water arsenic was related to a significant reduction of FEV1 (-74.4 ml, P < 0.01; and -116.1 ml, P < 0.05) and FVC (-72.8 ml, P = 0.02; and -146.9 ml, P = 0.004), respectively. This large population-based study confirms that arsenic exposure is associated with impaired lung function and the deleterious effect is evident at low- to moderate-dose range.

    The aim was to elucidate the relationship between the annual changes in respiratory system impedance, measured by FOT, and lung function tests in patients with asthma. Between March 2011 and March 2012, asthma outpatients who attended Kobe City Medical Center West Hospital were recruited. Lung function tests, FOT were conducted every 6 months until March 2016. The relationships between annual parameter changes were evaluated. Sixty-four patients were completed this study. The median follow-up period was 55 months. At enrollment, although resistance showed no relationship with forced expiratory volume in one second (%FEV1), the reactance was moderately correlated with X5 (r=0.524, r(2)=0.275, <0.001), Fres (r=-0.498, r(2)=0.248, <0.001) and ALX (r=-0.416, r(2)=0.173, p=<0.001). By contrast, the annual resistance change at 5Hz (R5) was highly and significantly associated with%FEV1 change (r=-0.564, r(2)=0.318, p<0.001).

    Cognitive decline is a characteristic feature of normal human aging. Previous work has demonstrated marked interindividual variability in onset and rate of decline. Such variability has been linked to factors such as maintenance of functional and structural brain integrity, genetics, and lifestyle. Still, few, if any, studies have combined a longitudinal design with repeated multimodal imaging and a comprehensive assessment of cognition as well as genetic and lifestyle factors. The present paper introduces the Cognition, Brain, and Aging (COBRA) study, in which cognitive performance and brain structure and function are measured in a cohort of 181 older adults aged 64 to 68 years at baseline. Participants will be followed longitudinally over a 10-year period, resulting in a total of three equally spaced measurement occasions. The measurement protocol at each occasion comprises a comprehensive set of behavioral and imaging measures. Cognitive performance is evaluated via computerized testing of working memory, episodic memory, perceptual speed, motor speed, implicit sequence learning, and vocabulary. Brain imaging is performed using positron emission tomography with [(11)C]-raclopride to assess dopamine D2/D3 receptor availability. Structural magnetic resonance imaging (MRI) is used for assessment of white and gray-matter integrity and cerebrovascular perfusion, and functional MRI maps brain activation during rest and active task conditions. Lifestyle descriptives are collected, and blood samples are obtained and stored for future evaluation. Here, we present selected results from the baseline assessment along with a discussion of sample characteristics and methodological considerations that determined the design of the study.

    Development of payment systems for mental health services has been hindered by limited evidence for the utility of diagnosis or symptoms in predicting costs of care. We investigated the utility of functioning information in predicting costs for patients with mood and anxiety disorders. This was a prospective cohort study involving 102 adult patients attending a tertiary referral specialist clinic for mood and anxiety disorders. The main outcome was total costs, calculated by applying unit costs to healthcare use data. After adjusting for covariates, a significant total costs association was yielded for functioning (e=1.02; 95% confidence interval: 1.01-1.03), but not depressive symptom severity or anxiety symptom severity. When we accounted for the correlations between the main independent variables by constructing an abridged functioning metric, a significant total costs association was again yielded for functioning (e=1.04; 95% confidence interval: 1.01-1.09), but not symptom severity. The utility of functioning in predicting costs for patients with mood and anxiety disorders was supported. Functioning information could be useful within mental health payment systems.

    A number of studies have called attention to the problematic interplay between depression and anxiety symptoms and sexual difficulties. However, despite the bidirectional conceptualization of the association between affective and sexual problems, few studies have adequately examined temporal precedence or state-level fluctuations between these two constructs. Using Clark and Watson's (1991) tripartite model of anxiety and depression, the current study employed a repeated measures design to examine how weekly changes in affective symptoms were related to weekly changes in sexual functioning in a non-clinical sample of premenopausal women. First, we examined how general distress, anxious arousal, and anhedonia were concurrently related to various indices of sexual functioning. Next, we examined lagged effects of mood and anxiety symptoms predicting later levels of sexual functioning. Finally, we tested sexual functioning's influence on later reports of affective symptoms. Hierarchical linear modeling analyses revealed that, of the three symptom types tested, anhedonic depression was the most consistently related to sexual problems, and that these relations were more proximal than distal. The preponderance of data suggested temporal precedence of mood on sexual symptoms. These findings emphasize the importance of prospective studies in the investigation of mental and sexual health.

    The immune cell function assay (ICFA) and de novo anti-donor-specific HLA antibodies (DSA) have been proposed as assays for immune monitoring in renal transplantation, but longitudinal studies examining the modification of both parameters over time and their relation with clinical events are lacking. We prospectively measured longitudinal changes in ICFA and DSA levels in 55 kidney transplant recipients over 3-year follow-up (534 visits) and analyzed their relation with the risk of developing acute rejections or infections. Seven patients (12.7%) developed biopsy-proven acute rejection, and 20 (36.4%) developed viral infections. At 3 years posttransplant, 28% of the patients had developed de novo DSA. ICFA levels peaked at 1-2 months posttransplant (p = 0.005) and leveled off thereafter. They were not associated with the risk of acute rejections, viral infections or development of de novo DSA. Instead, the incidence of de novo DSA was higher in patients who previously had viral infections (adjusted-odds ratio of de novo DSA associated with prior infections: 6.03 [95% CI, 1.64-22.06; p = 0.007]). Our prospective, longitudinal study does not support using ICFA to quantify the immune risk in kidney transplantation. Further studies are needed to confirm the relationship between viral infections and the subsequent development of de novo DSA. © Copyright 2013 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Previous studies have revealed psychosocial and cognitive impairments in patients during unipolar and bipolar depression, which persist even in subsyndromal and euthymic states. Currently, little is known about the nature and the extent of psychosocial and cognitive deficits during depression. The aim of the present study was to characterize psychosocial and cognitive profiles among unipolar (MDD) and bipolar (BD) patients during a major depressive episode and to compare the profiles of the patient groups. Depressed patients with MDD (n=13) and BD (n=11) were followed over a period of 12 months. Clinical, psychosocial and neuropsychological assessments were conducted at baseline and at 6-week, 4-month, 8-month and 12-month follow-ups. In the case of severe mood disorders, psychosocial and neurocognitive functioning seem similar among MDD and BD patients during a depressive episode. All MDD and BD patients had global psychosocial dysfunction, characterized by occupational and relational impairments. Furthermore, the neurocognitive profile was heterogeneous with regard to the nature and extent of cognitive deficits but attentional processes were frequently compromised. After 1 year of treatment, occupational and relational impairments, as well as neurocognitive dysfunction, persisted sufficiently to alter daily functioning.

    Rationale: Exposure to arsenic through drinking water has been linked to respiratory symptoms, obstructive lung diseases, and mortality from respiratory diseases. Limited evidence for the deleterious effects on lung function exists among individuals exposed to a high dose of arsenic. Objectives: To determine the deleterious effects on lung function that exist among individuals exposed to a high dose of arsenic. Methods: In 950 individuals who presented with any respiratory symptom among a population-based cohort of 20,033 adults, we evaluated the association between arsenic exposure, measured by well water and urinary arsenic concentrations measured at baseline, and post-bronchodilator–administered pulmonary function assessed during follow-up. Measurements and Main Results: For every one SD increase in baseline water arsenic exposure, we observed a lower level of FEV1 (−46.5 ml; P < 0.0005) and FVC (−53.1 ml; P < 0.01) in regression models adjusted for age, sex, body mass index, smoking, socioeconomic status, betel nut use, and arsenical skin lesions status. Similar inverse relationships were observed between baseline urinary arsenic and FEV1 (−48.3 ml; P < 0.005) and FVC (−55.2 ml; P < 0.01) in adjusted models. Our analyses also demonstrated a dose-related decrease in lung function with increasing levels of baseline water and urinary arsenic. This association remained significant in never-smokers and individuals without skin lesions, and was stronger in male smokers. Among male smokers and individuals with skin lesions, every one SD increase in water arsenic was related to a significant reduction of FEV1 (−74.4 ml, P < 0.01; and −116.1 ml, P < 0.05) and FVC (−72.8 ml, P = 0.02; and −146.9 ml, P = 0.004), respectively. Conclusions: This large population-based study confirms that arsenic exposure is associated with impaired lung function and the deleterious effect is evident at low- to moderate-dose range.

    To explore potential predictors of functional outcome one year after the injury in elderly women who sustained a displaced intracapsular hip fracture and who were treated with internal fixation, hemiarthroplasty, or total hip arthroplasty. Eighty-four women aged > or =50 years were enrolled on a consecutive basis in this one-year prospective cohort study reflecting standard day-to-day clinical practice. The main outcome measure was the rapid disability rating scale version-2 (RDRS-2) applied at hospital discharge and one year later. At hospital discharge, the total hip arthroplasty group was younger and had a better functional status than the internal fixation or hemiarthroplasty groups. One year later, the best function was still observed in the total arthroplasty group, but the differences were small and failed to achieve the level of statistical significance. During that one-year period, walking ability or mobility did not change significantly after total hip arthroplasty, but a significant proportion of the women developed cognitive impairment, including mental confusion, uncooperativeness, and depression. Overall, the most significant predictors of poor functional status one year after fracture were increasing age, living in an institution at time of injury, and poor functional status at discharge. In elderly women with a displaced intracapsular hip fracture, total hip arthroplasty is associated with a functional benefit within the first months after surgery. However, the extent to which this functional benefit is maintained over time, is less clear. These results support the need for randomised studies to quantify the extent to which, in elderly women, the early functional benefit of total hip arthroplasty is maintained in the long run or compromised by progressive cognitive impairment and other negative determinants of functional outcome.

    Premorbid functioning may be associated with treatment response, but this is confounded by a lack of prospective longitudinal data and controls for medication compliance. This study tested the hypothesis that good premorbid functioning will be associated with better antipsychotic treatment response after controlling for drug adherence by using a long-acting injectable antipsychotic. This was a 6-month, open label, multicenter, phase IV trial in recent-onset schizophrenia treated with flexible doses of risperidone long-acting injectable (25-50 mg every 14 days). Premorbid functioning was assessed with the Premorbid Adjustment Scale (PAS)-Structured Interview; efficacy was evaluated with clinician-rated Positive and Negative Syndrome Scale, Clinical Global Impression scale of Severity of Illness, Clinical Global Impression scale of Change, Global Assessment of Functioning Scale, and trial participant completed SF-36. Analyses controlled for baseline scores and demographics. With the use of a priori PAS scoring criteria, the participants' premorbid functioning was categorized as stable-good (n = 142), stable-poor (n = 116), and deteriorating (n = 36). At baseline, the stable-good group had the best functioning on most efficacy measures. All groups showed significant improvement on efficacy measures with treatment. Improvement was significantly higher for the stable-good group. The PAS global assessment of highest level of functioning scale (excellent, n = 75; good, n = 117; fair, n = 78; and poor, n = 31) showed a strong association with baseline functioning and improvement and had a significant linear association with meeting Remission in Schizophrenia Working Group symptom criteria at baseline (P = 0.003) and attained and sustained remission for 3 months during study (47.7%, 49.3%, 29.6%, and 22.2%; P = 0.006). Good premorbid functioning corresponds with better treatment response in recent-onset psychosis as captured on both clinician and patient-reported measures.

    To examine the associations between depression course, functional disability, and Not in Education or Training (NEET) status in a clinical sample of young adults with mental health problems. Young adults aged 15-25 years seeking help from four primary mental health services were invited to participate in a prospective cohort study evaluating the course of psychiatric disorders in youth. Demographic and clinical characteristics, including depressive symptomatology and functioning, were evaluated through clinical interview and self-report at baseline and 12 month follow-up. A total of 448 young adults participated (70 % female; M: 20.05 years, SD = 2.85). A significant interaction effect for time and depression course was found, such that those who became depressed reported an increase in functional disability and those whose depression remitted reported a significant reduction in functional disability. Developing depression was not a significant predictor of becoming NEET and vice versa: remitted depression did not make a person more likely to reengage in employment or education. This is the first study to examine the course of depression, functional disability, and NEET rates among help-seeking young adults. This study confirms the importance of symptom reduction for improved functioning; however, functional disability remained greater than that seen in young people in the community and there was no association between a change in depression and a change in NEET status. These results argue that services need to address functional outcomes and reengagement with education and employment in addition to symptom reduction.

    Ligninolytic extracellular enzymes, including lignin peroxidase, are topical owing to their high redox potential and prospective industrial applications. The prospective applications of lignin peroxidase span through sectors such as biorefinery, textile, energy, bioremediation, cosmetology, and dermatology industries. The litany of potentials attributed to lignin peroxidase is occasioned by its versatility in the degradation of xenobiotics and compounds with both phenolic and non-phenolic constituents. Over the years, ligninolytic enzymes have been studied however; research on lignin peroxidase seems to have been lagging when compared to other ligninolytic enzymes which are extracellular in nature including laccase and manganese peroxidase. This assertion becomes more pronounced when the application of lignin peroxidase is put into perspective. Consequently, a succinct documentation of the contemporary functionalities of lignin peroxidase and, some prospective applications of futuristic relevance has been advanced in this review. Some articulated applications include delignification of feedstock for ethanol production, textile effluent treatment and dye decolourization, coal depolymerization, treatment of hyperpigmentation, and skin-lightening through melanin oxidation. Prospective application of lignin peroxidase in skin-lightening functions through novel mechanisms, hence, it holds high value for the cosmetics sector where it may serve as suitable alternative to hydroquinone; a potent skin-lightening agent whose safety has generated lots of controversy and concern. © 2016 The Authors.

    This study prospectively evaluated the endocrine function of 11 children treated with cranial irradiation (CRT) for brain tumors. All tumors were remote from the hypothalamic-pituitary axis. Children were studied before treatment and at 3, 6, and 12 months after the completion of CRT. T4, thyroid-stimulating hormone, prolactin, plasma cortisol, and urinary follicle-stimulating hormone and luteinizing hormone values were normal before and after treatment in all patients. Growth hormone (GH) deficiency was identified in 0 of 7 patients before treatment, in 2 of 7 patients 3 months post-CRT, in 9 of 11 patients 6 months post-CRT, and in 7 of 8 patients 12 months post-CRT. Growth deceleration was identified in five of seven prepubertal patients. GH deficiency is an extremely common sequelae of CRT, beginning as early as 3 months after the completion of CRT. The deficit is progressive over time.

    Since many antidepressants can cause sexual dysfunction, the aim of this study was to follow-up sexual functions during mirtazapine (RemeronSolTab®) treatment. One hundred and two (44 male and 58 female) outpatients with major depression were recruited to this prospective, observational, non-interventional study. The screening was followed by three visits, during which the 17-HAMD, CGI and 9-BDI scales were used. The change of sexual life was monitored by a self-completing questionnaire, based on the modified Psychotropic-Related Sexual Dysfunction Questionnaire. During the treatment both the depression rating scales and the CGI have shown a significant improvement and significant amelioration of previous sexual problems was found; patients were evaluating their sexual life better and better. Our results indicated that mirtazapine is an effective tool for depressed patients who suffer from sexual dysfunction.

    The aim of this study was to evaluate the value of conventional factors, the Risk Assessment and Predictor Tool (RAPT) and performance-based functional tests as predictors of delayed recovery after total hip arthroplasty (THA). A prospective cohort study in a regional hospital in the Netherlands with 315 patients was attending for THA in 2012. The dependent variable recovery of function was assessed with the Modified Iowa Levels of Assistance scale. Delayed recovery was defined as taking more than 3 days to walk independently. Independent variables were age, sex, BMI, Charnley score, RAPT score and scores for four performance-based tests [2-minute walk test, timed up and go test (TUG), 10-meter walking test (10 mW) and hand grip strength]. Regression analysis with all variables identified older age (>70 years), Charnley score C, slow walking speed (10 mW >10.0 s) and poor functional mobility (TUG >10.5 s) as the best predictors of delayed recovery of function. This model (AUC 0.85, 95% CI 0.79-0.91) performed better than a model with conventional factors and RAPT scores, and significantly better (p = 0.04) than a model with only conventional factors (AUC 0.81, 95% CI 0.74-0.87). The combination of performance-based tests and conventional factors predicted inpatient functional recovery after THA. Two simple functional performance-based tests have a significant added value to a more conventional screening with age and comorbidities to predict recovery of functioning immediately after total hip surgery. Patients over 70 years old, with comorbidities, with a TUG score >10.5 s and a walking speed >1.0 m/s are at risk for delayed recovery of functioning. Those high risk patients need an accurate discharge plan and could benefit from targeted pre- and postoperative therapeutic exercise programs.

    Personal mastery has been associated with physical function maintenance later in life. Less is known about the relationship between lack of personal mastery and functional decline in Asian populations, and whether multisystem physiological dysregulation explains this relationship. Participants (n = 487) from the Social Environment and Biomarkers of Aging Study, a population-based prospective cohort study in Taiwan, received baseline measurements of personal mastery using the Pearlin Mastery Scale. Multisystem physiological dysregulation at baseline was assessed as a summary score based on the levels of 16 biomarkers of the hypothalamic-pituitary-adrenal axis, the sympathetic nervous system, the cardiovascular system, the metabolic system and the immune system functioning. Function in activities of daily living was determined at baseline and at a 7-year follow up. Participants in the lowest quartile of the personal mastery score were more likely to experience functional decline than those in the higher quartiles (OR comparing the lowest with highest 3 quartiles 2.99, 95% CI 1.71-5.21). After adjusting for confounders, personal mastery remained significantly associated with functional changes (adjusted OR 2.09, 95% CI 1.05-4.14). Greater sense of personal mastery was associated with significantly less multisystem physiological dysregulation (P for trend = 0.001). When the levels of physiological dysregulation were added to the multivariate models, the association between a poor sense of personal mastery and functional decline was attenuated. Lack of personal mastery is independently associated with an increased risk of functional decline in older adults. Multisystem physiological dysregulation partially explains this relationship. © 2014 Japan Geriatrics Society.

    Endocrine evaluations were performed prospectively in 22 patients with medulloblastoma (ages 2 1/2 to 23 1/2 years at diagnosis), after craniospinal radiation with or without adjuvant chemotherapy. The mean craniospinal hypothalamic-pituitary). and thyroid radiation doses were 3600 and 2400 rads, respectively. Fourteen (73%) of 19 patients who had not yet completed their growth experienced a decrease in growth velocity. However, only three of 10 of these children, who underwent growth hormone stimulation tests, had evidence of deficient growth hormone responses, suggesting that growth hormone secretory or regulatory dysfunction, rather than absolute growth hormone deficiency, is present in the majority of these children. Elevated thyroid-stimulating hormone levels were noted in 15 of 22 patients; one patient had hypothalamic hypothyroidism. Thus, the late effects of therapy for medulloblastoma include frequent endocrine morbidity involving hypothalamic-pituitary and thyroid dysfunction.

    To examine the development and determinants of long-term outcomes for earthquake victims with amputations, including physical function, pain, quality of life and life satisfaction. Prospective cohort study with 2-3 measurement points. A total of 72 people who underwent amputations following the 2008 Sichuan Earthquake and resided in Mianzhu County, Sichuan Province, China were enrolled in the study. Of these, 27 people were lost to follow-up. Data on pain (visual analogue scale) and physical function (Barthel Index) were collected at 3 measurement points (2009, 2010 and 2012), and data on quality of life (Medical Outcomes Short-Form 36) and life satisfaction (Life Satisfaction Questionnaire-11) were collected at 2 measurement points (2010 and 2012). Data were analysed with mixed effects regression. Pain severity declined significantly and physical function increased by 2012. Quality of life and life satisfaction remained relatively stable between 2010 and 2012, while quality of life was significantly lower than reference values from the general population. Illiteracy and lower extremity amputations were associated with lower quality of life and life satisfaction in several domains. While amputees' functioning and pain were improved over time, quality of life and life satisfaction did not change. Illiterate earthquake survivors and those with lower extremity amputations are at particular risk of low quality of life and life satisfaction, and may require additional attention in future earthquake rehabilitation programs.

    Background: Displaced Colles’ fractures are treated by manipulation and below elbow cast application. Malunion is a common complication, resulting in pain, mid-carpal instability, and post-traumatic arthritis. Fracture stabilization by percutaneous pinning is a simple, minimally invasive technique that helps prevent displacement of the fracture, thereby minimizing complications. This study aims to assess the amount of collapse after closed manipulation and percutaneous pinning with Kirschner wires (K-wires) and its correlation with the functional outcome of the wrist after union. Methods: A prospective study was conducted from May 2015 to May 2016 in a tertiary orthopedic center. Ninety patients (60 females, 30 males) with an average age of 54.93 years with Type II fractures underwent closed manipulation and percutaneous pinning with crossed K-wires as the primary procedure. Serial radiographs were taken to document the amount of collapse. The functional outcome was assessed using the Cooney Wrist Score. Results: At the final follow-up at six months, the collapse in the mean dorsal angle was 0.94 and mean ulnar variance was 0.51. Functionally, 48 patients (53.33%) had an excellent outcome, 36 patients (40%) had a good outcome, and six patients (6.67%) had a fair outcome. Conclusions: Displaced Colles’ fractures should be reduced and stabilized with percutaneous K-wires to achieve an excellent functional outcome. PMID:28191366

    Functional outcomes are important in children with cochlear implants (CI) and additional disabilities as studies on auditory skill and speech/language development may not identify functional benefits from implantation. This study sought to measure functional performance skills of young children with developmental disabilities post-CI. Eight children with cognitive disabilities undergoing cochlear implantation were enrolled in a prospective study of language and functional abilities; 6 with 1 year follow-up were included in the analysis. Functional performance was measured using Pediatric Evaluation of Disability Inventory (PEDI), providing standardized (mean: 50) and scaled scores (range: 0-100) of functional domains: Self-Care, Mobility and Social Function. The PEDI was administered pre-implant, 6 and 12 months post-implantation along with language testing at the same intervals. All children had cognitive disability; 5 also had motor delay. The ages at CI ranged from 13.8 to 134 months. For functional abilities, children did not make significant changes in domain-specific standard scores over 1 year. Children made progress in scaled scores by 1-year post-implant. The largest increase for all domains occurred in the first 6 months (7-11.5 point increase). For language abilities, children made a median 5.5-month increase in receptive language age (p=0.06) and 5-month increase in expressive language age (p=0.03) in the first year post-CI with no change in language quotients. Receptive language level was significantly (p<0.05) associated with increasing scores in the domains of Self-Care and Social Function. This is the first study to measure daily functional abilities in children with implants and disabilities using a standardized tool. Although our small group of complex children did not have an increase in standard scores (gap-closing trajectories), they made progress in skill development on scaled scores. Receptive language appears to play a key role in social

Methods and Materials: A total of 39 consecutive eligible women, who underwent postoperative irradiation for breast cancer, were entered in the study. Spirometry consisting of forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV{sub 1}), carbon monoxide diffusing capacity (DLCO), and gammagraphic (ventilation and perfusion) pulmonary function tests (PFT) were performed before RT and 6, 12, and 36 months afterwards. Dose-volume and perfusion-weighted parameters were obtained from 3D dose planning: Percentage of lung volume receiving more than a threshold dose (V{sub i}) and between 2 dose levels (V{sub (i-j)}). The impact of clinical and dosimetric parameters on PFT changes ({delta}PFT) after RT was evaluated by Pearson correlation coefficients and stepwise lineal regression analysis. Results: No significant differences on mean PFT basal values (before RT) with respect to age, smoking, or previous chemotherapy (CT) were found. All the PFT decreased at 6 to 12 months. Furthermore FVC, FEV{sub 1}, and ventilation recovered almost to their previous values, whereas DLCO and perfusion continued to decrease until 36 months (-3.3% and -6.6%, respectively). Perfusion-weighted and interval-scaled dose-volume parameters (pV{sub (i-j)}) showed better correlation with {delta}PFT (only {delta}perfusion reached statistically significance at 36 months). Multivariate analysis showed a significant relation between pV{sub (10-20)} and {delta}perfusion at 3 years, with a multiple correlation coefficient of 0.48. There were no significant differences related to age, previous chemotherapy, concurrent tamoxifen and smoking, although a tendency toward more perfusion reduction in older and nonsmoker patients was seen. Conclusions: Changes in FVC, FEV{sub 1} and ventilation were reversible, but not the perfusion and DLCO. We have not found a conclusive

    Functional dyspepsia (FD) is a functional gastrointestinal disorder diagnosed by symptom-based criteria. It has been said that duodenal immune activation plays a role in the pathogenesis of FD. The primary aims of the study were to compare the total number of duodenal eosinophil and evaluate the eosinophil degranulation rate, number of duodenal degranulated eosinophil and mast cell between patients with FD and healthy subjects. We enrolled 96 patients with FD and 24 healthy controls at Sir Run Run Shaw Hospital. The total number of eosinophil was comparable in the second portion of duodenum (D2) and duodenal bulb (D1) between patients with FD and healthy controls (all P > 0.05). Significant higher eosinophil degranulation positive rate in D2 (P = 0.003) and a trend towards higher in D1 (P = 0.084) were observed in patients with FD compared with healthy controls. Moreover, the number of duodenal degranulated eosinophil in patients with FD were significantly increased than healthy controls in D1(9.8 ± 6.3 vs 2.9 ± 2.1 per HPF, P = 0.0002) and a trend towards increase in D2 (10.7 ± 7.7 vs 5.3 ± 0.9 per HPF, P = 0.077), respectively. However, degranulated mast cells in patients with FD were almost same with healthy controls. Increased eosinophils degranulation in duodenum play an important role in pathogenesis of FD.

    Voice and throat dysfunction may occur in patients after thyroidectomy, even in the absence of apparent laryngeal nerve injury. We evaluated the impact of thyroid surgery on voice and throat function using perceptive, objective, and subjective measurements in a prospectively enrolled and serially followed cohort of thyroid cancer patients. We assessed the impact of surgical extent and intensity of postoperative treatment, including addition radioactive iodine treatment (RIT), on these functions. Consenting patients undergoing thyroid lobectomy (TL; n = 33), total thyroidectomy (TT; n = 41), or TT plus RIT (n = 81), none of whom had laryngeal nerve dysfunction perioperatively, were enrolled prospectively. All underwent comprehensive functional evaluations, including perceptive voice quality using the grade, roughness, breathiness, asthenia, strain (GRBAS) scale and acoustic voice analysis with multiple parameters, and filled out subjective questionnaires, including the Voice Handicap Index (VHI) and the Glasgow Edinburgh Throat Scale, before thyroidectomy and at 1, 6, and 12 months postoperatively. In this study, 14-83% of the patients developed some element of voice and throat dysfunction, shown consistently in different evaluations. Typical patterns were alterations of perceptive voice, deranged acoustic parameters, and subjective worsening on the VHI and GETS. Moreover, these changes were correlated with the extent of treatment, especially within 3 months after operation, and often persisted 12 months postoperatively. RIT had no effects on voice outcomes throughout the follow-up. Voice and throat dysfunction are evident after thyroidectomy, more severely after TT than TL. These potential disabilities should be considered carefully to further enhance patients' quality of life. Copyright © 2013 Mosby, Inc. All rights reserved.

    To test the hypothesis that intensity modulated radiation therapy (IMRT) can reduce radiation dose to functional bone marrow (BM) in patients with pelvic malignancies (phase IA) and estimate the clinical feasibility and acute toxicity associated with this technique (phase IB). We enrolled 31 subjects (19 with gynecologic cancer and 12 with anal cancer) in an institutional review board-approved prospective trial (6 in the pilot study, 10 in phase IA, and 15 in phase IB). The mean age was 52 years; 8 of 31 patients (26%) were men. Twenty-one subjects completed (18)F-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) simulation and magnetic resonance imaging by use of quantitative IDEAL (IDEAL IQ; GE Healthcare, Waukesha, WI). The PET/CT and IDEAL IQ were registered, and BM subvolumes were segmented above the mean standardized uptake value and below the mean fat fraction within the pelvis and lumbar spine; their intersection was designated as functional BM for IMRT planning. Functional BM-sparing vs total BM-sparing IMRT plans were compared in 12 subjects; 10 were treated with functional BM-sparing pelvic IMRT per protocol. In gynecologic cancer patients, the mean functional BM V(10) (volume receiving ≥10 Gy) and V(20) (volume receiving ≥20 Gy) were 85% vs 94% (P<.0001) and 70% vs 82% (P<.0001), respectively, for functional BM-sparing IMRT vs total BM-sparing IMRT. In anal cancer patients, the corresponding values were 75% vs 77% (P=.06) and 62% vs 67% (P=.002), respectively. Of 10 subjects treated with functional BM-sparing pelvic IMRT, 3 (30%) had acute grade 3 hematologic toxicity or greater. IMRT can reduce dose to BM subregions identified by (18)F-fluorodeoxyglucose-PET/CT and IDEAL IQ. The efficacy of BM-sparing IMRT is being tested in a phase II trial. Copyright © 2013 Elsevier Inc.

    We conducted a cross-cultural comparison of the recovery of sexual function and bother during the first 2 years after radical prostatectomy (RP) between American and Japanese men. A total of 275 Japanese and 283 American men who underwent RP alone were prospectively enrolled into longitudinal cohort studies of health-related quality of life outcomes. Sexual function and bother (distress) were estimated with English and validated Japanese versions of the UCLA Prostate Cancer Index before RP and 1, 2-3, 4-6, 12, 18 and 24 months after RP. Each subject served as his own control. Japanese men reported lower sexual function scores at baseline, even after adjusted for age, prostate-specific antigen (PSA) and comorbidity (38 vs 61, P<0.001). The two groups had similar baseline sexual bother (70 vs 69, P=0.84). Japanese men had a smaller improvement in sexual function (beta=0.8 vs beta=5.3) and bother (beta=0.2 vs beta=2.9) over time than did the American men postoperatively, after adjusting for baseline score, age, baseline PSA and nerve-sparing. American men were more likely than Japanese men to regain their baseline sexual function by 24 months after surgery (hazard ratio (HR)=1.60; 95% confidence interval (CI)=1.06-2.42). In contrast, American men were less likely than Japanese men to return to baseline sexual bother (HR=0.57; 95% CI=0.44-0.75). This study demonstrates that Japanese and American men experience different patterns of recovery of their sexual function and bother after RP. Ethnicity may be a contributing factor.

    The newly developed three dimensional speckle-tracking echocardiography (3D-STE) technology provides quick and comprehensive quantitative assessment of biventricular myocardial dynamics. The impact of coronary slow flow phenomenon (CSFP) on biventricular functions has not been comprehensively evaluated using this new technology. Therefore, the aim of this study was to evaluate the effects of CSFP on biventricular systolic functions using 3D-STE. Forty patients with CSFP and otherwise normal coronary arteries (NCAs) and 40 age- and sex-matched controls with normal coronary angiograms (CAGs) were prospectively enrolled. Biventricular systolic function was evaluated by 3D-STE. Left ventricular (LV) global longitudinal, circumferential and radial strains, ejection fraction (EF) were significantly lower and LV end-systolic volume (ESV) was significantly higher in the CSFP group compared to the control group. There were no significant differences in LV mass, LV end-diastolic volume (EDV) or LV stroke volume (SV). Additionally, Right ventricular (RV) free wall, septal wall and global longitudinal strains, and RV EF were significantly lower in the CSFP group, but there were no significant differences in RV EDV, ESV and RV SV. The present study demonstrated that CSFP has a notable negative effect on not only 3D strain parameters but also biventricular EF. There was a strong correlation between the strain parameters of the affected vessel's myocardial area and the TIMI frame count of same vessel.

    Cervical cancer (CC) treatments impact quality of life (QoL) and sexual function (SF) of survivors. Treatment options to reduce sexual dysfunction are limited. The aim of this study was to assess the effectiveness of ospemifene in CC survivors with clinical signs and symptoms of vulvovaginal atrophy (VVA) focusing on their QoL and SF. Fifty-two patients with previous diagnosis of stage I-IIa CC suffering from VVA and treated with ospemifene were enrolled into a single arm prospective study. Patient underwent 6 months of therapy. At baseline and after 6 months all subjects performed Vaginal Health Index (VHI). The SF and QoL were measured by The European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ) and the Cervical Cancer Module (CXC-24). After treatment a significant improvement of each parameter of VHI has been demonstrated. Global health status and emotional and social functioning scores improved significantly. On the contrary, general symptoms scales did not show significant difference from baseline data. Sexual activity, sexual vaginal functioning, body image, and sexual enjoyment scores increased significantly. Ospemifene seems to be effective in decreasing the VVA symptoms in CC survivors.

    The true incidence of obstetric anal sphincter injuries (OASI) among Asian primigravida is not known. This study aimed to evaluate OASI in Sri Lankan primigravida. One hundred and one consecutive primigravida in their last trimester were recruited from antenatal clinics at a tertiary care centre in Sri Lanka and followed up 6 weeks and 6 months after delivery. They were assessed using anorectal manometry (3D-ARM) and endoanal ultrasound (3D-EAUS) on both occasions. Seventy-three (75.3 %) had vaginal delivery without instrumentation, whereas 3 (3.1 %) each delivered using forceps or vacuum. Twelve (12.4 %) had emergency caesarean sections and 6 (6.2 %) had elective caesarean sections. None had clinically identified anal sphincter injuries. EAUS identified IAS defects in 3 (5.1 %) and EAS defects in 28 (47.5 %). Both resting (p = 0.3) and squeeze (p = 0.001) pressures had decreased following childbirth. Multivariate analysis identified antepartum RP and postpartum EAS defects to be associated with RP reduction (χ(2)(4)=17.825, p < 0.0005) and antepartum SP and postpartum EAS defects to be associated with SP reduction (χ(2)(5)=31.517, p < 0.0005). Episiotomy was protective, whereas delivering after 40 weeks' gestation and delivering a baby with a longer length increased the risk of SP reduction. EAS defects (χ(2) (6)=23.502, p = .001) were more common in mothers who had labour augmented by oxytocin and in those who delivered a baby with a larger head circumference. Labour induction and delivering a longer baby were protective for EAS defects. Several risk and protective factors for the structural and functional damage of sphincters were identified. These findings will help to formulate a policy to minimize future obstetric anal sphincter injuries.

    We hypothesized that subclinical markers of vascular structure and function, which are independent predictors of cardiovascular disease, would be less frequent in subjects with ideal than poor cardiovascular health (CVH) as defined by the American Heart Association (AHA). Carotid parameters were measured using high-precision echotracking device in 9155 nonreferred participants attending a health checkup in a large health center in Paris (France) between 2008 and 2012. According to the AHA, participants with 0 to 2, 3 to 4, and 5 to 7 metrics (smoking, physical activity, body mass index, diet, blood glucose and total cholesterol, blood pressure) at the ideal level were categorized as having poor, intermediate, and ideal CVH. Carotid parameters were dichotomized according to their median value, and multivariable logistic regression analysis was performed. Mean age was 59.5 (SD 6.3) years; 39% were females, and ideal CVH was present in 10.11% of the study participants. After adjustment for age, sex, education, and living alone and compared with a poor CVH, an ideal CVH was associated with lower common carotid artery intima-media thickness (odds ratio=1.64; 95% confidence interval 1.40, 1.93), absence of carotid plaques (odds ratio=2.14; 95% confidence interval 1.60, 2.87), lower Young's elastic modulus (odds ratio=2.43; 95% confidence interval 2.07, 2.84), and higher carotid distensibility coefficient (odds ratio=2.90; 95% confidence interval 2.47, 3.41). In community subjects aged 50 to 75 years, ideal CVH was associated with substantially less arterial stiffness and thickness. These associations might contribute to the lower risk of cardiovascular diseases in subjects with ideal CVH. © 2016 American Heart Association, Inc.

    Chronic kidney disease (CKD) is characterized by increased risks of morbidity and mortality. Upper-body subcutaneous fat, which is commonly estimated from the neck circumference (NC), was revealed to be the main reservoir of circulating nonesterified fatty acids in overweight patients. Despite a close association between NC and metabolic complications, the relationship of NC with renal function has not been fully investigated. In this study, the impact of NC on the development of incident CKD was elucidated.The data were retrieved from the Korean Genome and Epidemiology Study cohort. The subjects were followed at 2-year intervals from 2003 to 2011. Overweight was defined as a body mass index of ≥23 kg/m. A total of 4298 cohort subjects were screened. After exclusion, 2268 overweight subjects were included for the final analysis. The primary end point was incident CKD, which was defined as a composite of estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m or the development of proteinuria.The mean patient age was 36.3 ± 3.0 years, and 1285 (56.7%) were men. They were divided into 2 groups according to the median NC in male and female subjects, separately. In both sexes, hypertension (men, P < 0.001; women, P = 0.009) and diabetes (men, P = 0.002; women, P < 0.001) were significantly more prevalent in the big NC group than in the small NC group. In contrast, eGFR was significantly lower only in male subjects of the big NC group (P < 0.001), whereas it was comparable between the small and big NC groups (P = 0.167). In multivariate Cox proportional hazards regression analysis, NC values were independently associated with incident CKD development in female subjects after adjusting for multiple confounding factors (per 1 cm increase, hazard ratio [95% confidence interval] = 1.159 [1.024-1.310], P = 0.019) but not in male subjects.NC is independently associated with the development of CKD in overweight female subjects, suggesting

    Previous studies have reported that elderly victims of natural disasters might be prone to a subsequent decline in motor function. Victims of the Great East Japan Earthquake (GEJE) relocated to a wide range of different types of housing. As the evacuee lifestyle varies according to the type of housing available to them, their degree of motor function loss might also vary accordingly. However, the association between postdisaster housing type and loss of motor function has never been investigated. The present study was conducted to investigate the association between housing type after the GEJE and loss of motor function in elderly victims. We conducted a prospective observational study of 478 Japanese individuals aged ≥65 years living in Miyagi Prefecture, one of the areas most significantly affected by the GEJE. Information on housing type after the GEJE, motor function as assessed by the Kihon checklist and other lifestyle factors was collected by interview and questionnaire in 2012. Information on motor function was then collected 1 year later. The multiple logistic regression model was used to estimate the multivariate adjusted ORs of motor function loss. We classified 53 (11.1%) of the respondents as having loss of motor function. The multivariate adjusted OR (with 95% CI) for loss of motor function among participants who were living in privately rented temporary housing/rental housing was 2.62 (1.10 to 6.24) compared to those who had remained in the same housing as that before the GEJE, and this increase was statistically significant. The proportion of individuals with loss of motor function was higher among persons who had relocated to privately rented temporary housing/rental housing after the GEJE. This result may reflect the influence of a move to a living environment where few acquaintances are located (lack of social capital). Published by the BMJ Publishing Group Limited.

    Patients with intracranial meningiomas can experience neurocognitive dysfunctions in specific cognitive domains depending on tumor location and size. The literature regarding cognitive function surrounding the resection of frontal meningiomas is sparse. We performed a prospective matched-control study to investigate the cognitive performance of frontal meningioma patients undergoing resection. The neurocognitive status 1 week and 2 months after resection was compared with the preoperative status and matched-controls. Matching was performed for age, sex, handedness, education, and profession. An extensive test battery was used to assess perceptual speed, executive function, visual-spatial and verbal working memory, short- and long-term memory, verbal fluency, fluid intelligence, anxiety, and depression. Twelve patients with frontal World Health Organization grade I meningioma and 12 matched-controls underwent cognitive testing. Macroscopically, complete removal was achieved in all cases. Comparison of patients and controls revealed significant cognitive impairments in perceptual speed, executive function, short-term memory, and verbal fluency preoperatively and postoperatively. At 2 months' follow-up, perceptual speed and verbal fluency were still significantly impaired, whereas executive function and short-term memory were equal to that in the control group. None of the patients experienced cognitive deterioration after surgical therapy. Patients with frontal meningiomas display preoperative and postoperative deficits in perceptual speed, executive function, short-term memory, and verbal fluency. The risk for cognitive deterioration owing to surgical resection is low. Within the first two months after surgery, executive function and short-term memory appear to recover.

    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

    The aim of the study was to identify the predictors of functioning in Chinese people with serious mental illness. Mental healthcare services for people suffering from serious mental illness are delivered to not only minimise their psychiatric symptoms but also enhance their levels of functioning in the community. Yet, there is insufficient research directed towards the associated or predictive factors that may influence different aspects of functioning, particularly in terms of patients' psychosocial variables. A longitudinal, prospective cohort study design was adopted. A clustered random sample of 395 of 611 outpatients with serious mental illness completed the same set of questionnaires at baseline and at 12 months. Changes in patients' functioning as measured by self-maintenance, social functioning and community living skills were recorded over 12 months. Potential relationships between their level of functioning and symptom severity, self-esteem, self-efficacy, perceived negative familial response, negative self-stigma towards mental illness, re-hospitalisation rate and socio-demographic characteristics were investigated. Most participants reported moderate to moderately high levels of overall functioning, self-efficacy, self-stigma and perceived negative familial response at baseline and there were significant observed correlations between these variables. Results of multiple regression models indicated that while symptom severity predicted functioning in patients with psychotic and affective disorders, a negatively perceived familial response only predicted negative changes in social functioning of the patients with psychotic disorders (β = -0·25). In addition, improvements in self-efficacy (β = 0·23) and reduction in self-stigma (β = -0·15) positively predicted changes in the community living skills of patients with affective disorders. The findings indicate the significance of psychiatric patients' symptom management and factors such as self

    Background The aim of this research was to study the clinical characteristics and mortality and disability outcomes of patients who present distinct risk profiles for functional decline at admission. Methods Multicenter, prospective cohort study conducted between 2006 and 2009 in three hospitals in the Netherlands in consecutive patients of ≥65 years, acutely admitted and hospitalized for at least 48 hours. Nineteen geriatric conditions were assessed at hospital admission, and mortality and functional decline were assessed until twelve months after admission. Patients were divided into risk categories for functional decline (low, intermediate or high risk) according to the Identification of Seniors at Risk-Hospitalized Patients. Results A total of 639 patients were included, with a mean age of 78 years. Overall, 27%, 33% and 40% of the patients were at low, intermediate or high risk, respectively, for functional decline. Low-risk patients had fewer geriatric conditions (mean 2.2 [standard deviation [SD] 1.3]) compared with those at intermediate (mean 3.8 [SD 2.1]) or high risk (mean 5.1 [SD 1.8]) (p<0.001). Twelve months after admission, 39% of the low-risk group had an adverse outcome, compared with 50% in the intermediate risk group and 69% in the high risk group (p<0.001). Conclusion By using a simple risk assessment instrument at hospital admission, patients at low, intermediate or high risk for functional decline could be identified, with distinct clinical characteristics and outcomes. This approach should be tested in clinical practice and research and might help appropriately tailor patient care. PMID:22238628

    To evaluate women's sexual function, self-esteem, body image, and health-related quality of life after colorectal surgery. Current literature lacks prospective studies that evaluate female sexuality/quality of life after colorectal surgery using validated instruments. Sexual function, self-esteem, body image, and general health of female patients undergoing colorectal surgery were evaluated preoperatively, at 6 and 12 months after surgery, using the Female Sexual Function Index, Rosenberg Self-Esteem scale, Body Image scale and SF-36, respectively. Ninety-three women with a mean age of 43.0 +/- 11.6 years old were enrolled in the study. Fifty-seven (61.3%) patients underwent pelvic and 36 (38.7%) underwent abdominal procedures. There was a significant deterioration in overall sexual function at 6 months after surgery, with a partial recovery at 12 months (P = 0.02). Self-esteem did not change significantly after surgery. Body image improved, with slight changes at 6 months and significant improvement at 12 months, compared with baseline (P = 0.05). Similarly, mental status improved over time with significant improvement at 12 months, with values superior than baseline (P = 0.007). Physical recovery was significantly better than baseline in the first 6 months after surgery with no significant further improvement between 6 and 12 months. Overall, there were no differences between patients who had abdominal procedures and those who underwent pelvic dissection, except that patients from the former group had faster physical recovery than patients in the latter (P = 0.031). When asked about the importance of discussing sexual issues, 81.4% of the woman stated it to be extremely or somewhat important. Surgical treatment of colorectal diseases leads to improvement in global quality of life. There is, however, a significant decline in sexual function postoperatively. Preoperative counseling is desired by most of the patients.

    The aim of this prospective study was to objectively evaluate inferior alveolar nerve (IAN) sensory disturbances in patients who underwent sagittal split ramus osteotomy (SSRO) by comparing 1 side treated with a reciprocating saw with the other side treated with a piezosurgery device. Clinical evaluation of IAN sensory disturbance was undertaken preoperatively and at 1 week, 4 weeks, 2 months, and 6 months postoperatively in 20 patients who underwent SSRO at the Division of Oral and Maxillofacial Surgery, Araraquara Dental School, São Paulo State University. The 20 patients were examined at all periods for IAN functionality by Semmes-Weinstein testing; neither the patients nor the examiner knew which side was treated using piezosurgery or a reciprocating saw. The mean age of the patients was 28.4 years (range, 20 to 48 yr). Before surgery, no patient had impaired function of the IAN in any of the 8 zones in the mental and inferior lip areas. All patients reported feeling the first monofilament at the time of the preoperative test. Seven days postoperatively, all patients reported some kind of altered sensitivity in at least 1 zone evaluated. The results of this study suggest there was no statistically significant difference in the sensitivity of the labiomental area regarding the instrument used to perform the osteotomy. Future studies will focus on enlarging the sample and evaluating the results. Copyright © 2014 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

    Current hypotheses suggest that intake of fruit and vegetables (FVs) protects against age-related cognitive impairment. We examined the 13-y association between FV intake and cognitive performance in a sample of French adults. A total of 2533 subjects aged 45-60 y at baseline, who were part of the Supplementation with Antioxidant Vitamins and Minerals 2 (SU.VI.MAX 2) cohort, were selected. FV intake was estimated at baseline in participants who had completed at least six 24-h dietary records. Cognitive performance was assessed 13 y after baseline and included an evaluation of verbal memory (RI-48 cued recall, semantic, and phonemic fluency tests) and executive function (trail-making and forward and backward digit span tests). Principal components analysis was performed to account for correlations in test scores. The relation between cognitive performance and quartiles of FV intake was assessed by multivariate linear regression analyses. Intakes of FVs (P-trend = 0.02), fruit alone (P-trend = 0.04), vitamin C-rich FVs (P-trend = 0.03), vitamin C (P-trend = 0.005), and vitamin E (P-trend = 0.04) were positively associated with verbal memory scores. In contrast, intakes of FVs (P-trend = 0.006), vegetables alone (P-trend = 0.03), and β-carotene-rich FVs (P-trend = 0.02) were negatively associated with executive functioning scores. FVs might have a differential effect on cognition according to groups of FVs and type of cognitive function. Further research using sensitive and reliable measures of various types of cognitive function is needed to clarify the effect of individual FV groups and nutrients. This trial is registered at clinicaltrials.gov as NCT00272428.

    Natural killer (NK) cells comprise the main components of lymphocyte-mediated nonspecific immunity. Through their effector function they play a crucial role combating bacterial and viral challenges. They are also thought to be key contributors to the systemic spinal cord injury-induced immune-deficiency syndrome (SCI-IDS). SCI-IDS increases susceptibility to infection and extends to the post-acute and chronic phases after SCI. The prospective study of NK cell function after traumatic SCI was carried out in two centers in Berlin, Germany. SCI patients and control patients with neurologically silent vertebral fracture also undergoing surgical stabilization were enrolled. Furthermore healthy controls were included to provide reference data. The NK cell function was assessed at 7 (5-9) days, 14 days (11-28) days, and 10 (8-12) weeks post-trauma. Clinical documentation included the American Spinal Injury Association (ASIA) impairment scale (AIS), neurological level of injury, infection status, concomitant injury, and medications. The primary endpoint of the study is CD107a expression by NK cells (cytotoxicity marker) 8-12 weeks following SCI. Secondary endpoints are the NK cell's TNF-α and IFN-γ production by the NK cells 8-12 weeks following SCI. The protocol of this study was developed to investigate the hypotheses whether i) SCI impairs NK cell function throughout the post-acute and sub-acute phases after SCI and ii) the degree of impairment relates to lesion height and severity. A deeper understanding of the SCI-IDS is crucial to enable strategies for prevention of infections, which are associated with poor neurological outcome and elevated mortality. DRKS00009855 .

  12. Neighbourhood green space, physical function and participation in physical activities among elderly men: the Caerphilly Prospective study

    PubMed Central

    2014-01-01

    Background The built environment in which older people live plays an important role in promoting or inhibiting physical activity. Most work on this complex relationship between physical activity and the environment has excluded people with reduced physical function or ignored the difference between groups with different levels of physical function. This study aims to explore the role of neighbourhood green space in determining levels of participation in physical activity among elderly men with different levels of lower extremity physical function. Method Using data collected from the Caerphilly Prospective Study (CaPS) and green space data collected from high resolution Landmap true colour aerial photography, we first investigated the effect of the quantity of neighbourhood green space and the variation in neighbourhood vegetation on participation in physical activity for 1,010 men aged 66 and over in Caerphilly county borough, Wales, UK. Second, we explored whether neighbourhood green space affects groups with different levels of lower extremity physical function in different ways. Results Increasing percentage of green space within a 400 meters radius buffer around the home was significantly associated with more participation in physical activity after adjusting for lower extremity physical function, psychological distress, general health, car ownership, age group, marital status, social class, education level and other environmental factors (OR = 1.21, 95% CI 1.05, 1.41). A statistically significant interaction between the variation in neighbourhood vegetation and lower extremity physical function was observed (OR = 1.92, 95% CI 1.12, 3.28). Conclusion Elderly men living in neighbourhoods with more green space have higher levels of participation in regular physical activity. The association between variation in neighbourhood vegetation and regular physical activity varied according to lower extremity physical function. Subjects reporting poor lower extremity

    Background: Although habitual low-to-moderate alcohol intake has been linked with reduced all-cause mortality and morbidity, the effect of recent alcohol intake on female reproductive function has not been clearly established. Objective: We assessed the relation between acute alcohol consumption, reproductive hormones, and markers of menstrual cycle dysfunction including sporadic anovulation, irregular cycle length, luteal phase deficiency, long menses, and heavy blood loss. Design: A total of 259 healthy, premenopausal women from Western New York were followed for ≤2 menstrual cycles (2005–2007) and provided fasting blood specimens during ≤8 visits/cycle and four 24-h dietary recalls/cycle. Linear mixed models were used to estimate associations between previous day’s alcohol intake and hormone concentrations, whereas Poisson regression was used to assess RR of cycle-average alcohol intake and menstrual cycle function. Results: For every alcoholic drink consumed, the geometric mean total and free estradiol, total and free testosterone, and luteinizing hormone were higher by 5.26% (95% CI: 1.27%, 9.41%), 5.82% (95% CI: 1.81%, 9.99%), 1.56% (95% CI: 0.23%, 2.90%), 1.42% (95% CI: 0.02%, 2.84%), and 6.18% (95% CI: 2.02%, 10.52%), respectively, after adjustment for age, race, percentage of body fat, perceived stress, pain-medication use, sexual activity, caffeine, and sleep. Binge compared with nonbinge drinking (defined as reporting ≥4 compared with <4 drinks/d, respectively) was associated with 64.35% (95% CI: 18.09%, 128.71%) and 63.53% (95% CI: 17.41%, 127.73%) higher total and free estradiol. No statistically significant associations were shown between cycle-average alcohol intake and menstrual cycle function. Conclusion: Although recent moderate alcohol intake does not appear to have adverse short-term effects on menstrual cycle function, including sporadic anovulation, potential protective and deleterious long-term effects of alterations in reproductive

    Renal failure is one of the primary medium- to long-term morbidities in heart transplant (HT) recipients. To a great extent, this renal deterioration is associated with calcineurin inhibitors, primarily cyclosporine A (CsA). It has been suggested that tacrolimus provides better renal function in these patients. We assessed the medium-term evolution of renal function depending on the calcineurin inhibitor used after HT. We assessed 40 consecutive HT recipients over one year. Patients were randomized to receive CsA (n = 20) or tacrolimus (n = 20) in combination with mycophenolate mofetil (1 g/12 h) and deflazacort in decreasing dosages. We analyzed demographic variables before HT, creatinine values before and six months after HT and incidence of acute rejection. No demographic, clinical, or analytical differences were observed were between the two groups before HT. Repeated measures analysis of variance of creatinine values showed no significant differences between the two groups (P = .98). Furthermore, no differences were observed in either the incidence of rejection (P = .02) or rejection-free survival (P = .14). There seems to be no difference in efficacy profile and renal tolerability between CsA and tacrolimus therapy during the first months after HT.

    The testing of the implantable cardioverter-defibrillator (ICD), through the induction of repeated episodes of ventricular fibrillation, has been associated with disturbances in cerebral activity and increased levels of cytoplasmic enzymes. However, the neuropsychological outcomes of cerebral changes and their quality-of-life implications are unknown. Fifty-two ICD recipients completed standardized validated neuropsychological tests 1 to 3 days before ICD surgery and then 6 weeks, 6 months, and 12 months after surgery. They also completed psychometric tests measuring anxiety, depression, and quality of life. Between 31% and 39% of patients showed a significant neuropsychological impairment from their baseline function 6 weeks, 6 months, and 12 months after surgery. Ten percent of patients had late-onset deficits at 12 months only. Frequent areas of impairment were auditory and visual memory and attention. Neuropsychological impairment was not related to mood or quality of life at follow-up, although anxiety and depression predicted reduced quality of life. ICD implantation is associated with neuropsychological impairment that dissipates for the majority of recipients after 12 months. Short-term memory function and attention are particularly vulnerable to changes in oxygen during ICD testing. Although anxiety and depression are prevalent, there is little evidence for the direct impact of mood on cognition, and deficits appear not to be associated with reduced quality of life. These results provide evidence for longitudinal outcomes of ICD surgery and have implications for patient rehabilitation and adjustment.

    Head and neck cancer (HNC) patients may develop dysphagia due to muscle atrophy and fibrosis following chemoradiotherapy. Strengthening of the swallowing muscles through therapeutic exercise is potentially effective for improving swallowing function. We hypothesize that a customized Swallow Exercise Aid (SEA), developed for isometric and isokinetic strengthening exercises (against resistance), can help to functionally strengthen the suprahyoid musculature, which in turn can improve swallowing function. An effectiveness/feasibility study was carried out with ten senior healthy volunteers, who performed exercises 3 times per day for 6 weeks. Exercises included chin tuck against resistance (CTAR), jaw opening against resistance (JOAR), and effortful swallow exercises with the SEA. Multidimensional assessment consisted of measurements of maximum chin tuck and jaw opening strength, maximum tongue strength/endurance, suprahyoid muscle volume, hyoid bone displacement, swallowing transport times, occurrence of laryngeal penetration/aspiration and/or contrast residue, maximum mouth opening, feasibility/compliance (questionnaires), and subjective swallowing complaints (SWAL-QOL). After 6-weeks exercise, mean chin tuck strength, jaw opening strength, anterior tongue strength, suprahyoid muscle volume, and maximum mouth opening significantly increased (p < .05). Feasibility and compliance (median 86 %, range 48-100 %) of the SEA exercises were good. This prospective effectiveness/feasibility study on the effects of CTAR/JOAR isometric and isokinetic strengthening exercises on swallowing musculature and function shows that senior healthy subjects are able to significantly increase swallowing muscle strength and volume after a 6-week training period. These positive results warrant further investigation of effectiveness and feasibility of these SEA exercises in HNC patients with dysphagia.

    Leptin levels are elevated in obese humans. Several studies have shown an association between hyperleptinemia and development of atherosclerosis and cardiovascular disease (CVD), but the relationship between leptin and vascular function remains unclear. To evaluate associations between circulating plasma leptin and measures of vascular function in a large sample of elderly individuals from the community. This cross-sectional study included 1016 subjects aged 70 (50% women) from the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS). The invasive technique forearm plethysmography with intra-arterial infusions of acetylcholine and sodium nitroprusside was used for estimation of endothelial dependent vasodilatation (EDV) and endothelial independent vasodilatation (EIDV), respectively, in resistance arteries, and the non-invasive technique ultrasound assessed flow mediated vasodilation (FMD) in conduit arteries. The aortic augmentation index (AoAI), a surrogate measure of arterial stiffness, was evaluated by pulse wave analysis. Associations of vascular function, arterial stiffness and blood pressure with leptin were explored. In sex-adjusted models, high levels of leptin were inversely associated with EDV and EIDV. These associations remained after stratification for sex, traditional risk factors of CVD and insulin resistance, but were attenuated after taking a measure of obesity (body mass index) into account. In addition, leptin associated with arterial stiffness and systolic and diastolic blood pressure. Hyperleptinemia associated inversely with vasodilatation in resistance arteries. Furthermore, hyperleptinemia associated with arterial stiffness and hypertension. These associations were attenuated after adjusting for body mass index suggesting that leptin may be the mediator between obesity and impaired vascular function.

    Metacarpal diaphyseal fractures are classically treated using a non-removable glove for 4 to 6 weeks. Here, we report the results of treatment by immediate active protected mobilization (buddy taping for four weeks) of minimally displaced M2 to M5 fractures. Fifty-four fractures (15 transverse or short oblique and 39 spiral or long oblique) in 51 patients were included during a one-year period; the average age of patients was 31 years. Clinical and radiographic assessments were carried out at day 15 and then months 1, 2 and 6 post-fracture. Thirty-one cases were reviewed at day 15, 27 at 1 month, and 22 at 2 months. The initial volar tilt was 26° on average for the short oblique or transverse fractures, and 11.5° for the long oblique or spiral fractures. Six fractures (11%) experienced 16.6° of secondary displacement on average. The fracture was healed in 37% of cases at 1 month, and in 100% of cases at 2 months in the patients who were reviewed clinically. Reduction in the QuickDASH and VAS for pain was evidence of fast functional recovery. The range of motion was comparable to that of the contralateral side in 90% cases after 2 months. Grip and pinch strength was 33% less than the contralateral side at 2 months. Although secondary displacement occurs in some cases, the functional results of this simple and practical treatment method are good after 2 months, as there is little pain, stiffness, strength loss and no cases of nonunion.

    Although the number of elderly people needing care is increasing rapidly in the home setting in Japan, family size and ability to provide such support are declining. The purpose of this study was to identify the risk factors of functional disability by household composition among community-dwelling elderly people. A total of 1347 elderly people aged 70 years and over participated in a baseline geriatric health examination for this prospective cohort study. In the health examination, we conducted an interview survey using a questionnaire in July 2004 and July 2005. Questionnaire items covered the following: age, sex, household, medical history, instrumental activities of daily living, intellectual activity, social role, Motor Fitness Scale, falls experienced during the past year, Dietary Variety Score, frequency of going outdoors, cognitive impairment, and depressive status. We defined the occurrence of functional disability as certification for long-term care needs of the subjects. The certification process started with a home visit for an initial assessment to evaluate nursing care needs using a questionnaire on current physical and mental status. The onset of functional disability was followed from July 2004 to March 2011. Cox proportional hazard regression analysis was used to estimate the risk factors related to the onset of functional disability, adjusted for age and sex. Of the 1084 participants, 433 were male (39.9%), and the average age was 77.8 (standard deviation, 5.4). Up to March 2011, functional disabilities occurred in 226 participants (20.9%). Elderly people living only with their children demonstrated a significantly higher risk for functional disability than the three-generation household group (hazard ratio, 1.61; 95% confidence interval, 1.08-2.40). The risk factors for functional disability varied according to household group. In Japan, the number of vulnerable households with elderly people in need of care has increased steadily over the years

    To date, few studies focused on prediction of functional recovery after cerebellar stroke. The main aim of this prospective pilot study was to determine the association between cerebellar lesion location and functional outcome in adults with acute cerebellar infarction. We examined 14 patients with first-ever unilateral cerebellar ischemic stroke within 7 days and at 90 days from the onset of stroke by means of the International Cooperative Ataxia Rating Scale. Cerebellar lesions were traced from magnetic resonance imaging performed within 72 h since stroke and region of interest were generated. The association between the International Cooperative Ataxia Rating Scale score and lesion location was determined with the voxel-based lesion-symptom mapping methods implemented in the MRIcro software. Colored lesion-symptom maps representing the z statistics were generated and overlaid onto the MNI-ICBM 152 linear probabilistic atlas of the human brain and the Johns Hopkins University white matter templates. Our results documented that injuries to the V, VI, VIIA Crus I, VIIA Crus II, VIIB, VIIIA, and VIIIB lobules and the middle cerebellar peduncle are significantly associated with the International Cooperative Ataxia Rating Scale (ICARS) score at 1 week after the onset of stroke. Furthermore, we found that injuries to the VI, VIIA Crus I, VIIA Crus II, VIIB, VIIIA, and VIIIB lobules, the dentate nucleus, and the middle cerebellar peduncle are significantly associated with the ICARS score at 3 months since the cerebellar stroke onset. The findings of this pilot study might improve prognostic accuracy of functional outcome in patients with acute cerebellar infarction.

    Purpose Several lung cancer risk prediction models have been developed, but none to date have assessed the predictive ability of lung function in a population-based cohort. We sought to develop and internally validate a model incorporating lung function using data from the UK Biobank prospective cohort study. Methods This analysis included 502,321 participants without a previous diagnosis of lung cancer, predominantly between 40 and 70 years of age. We used flexible parametric survival models to estimate the 2-year probability of lung cancer, accounting for the competing risk of death. Models included predictors previously shown to be associated with lung cancer risk, including sex, variables related to smoking history and nicotine addiction, medical history, family history of lung cancer, and lung function (forced expiratory volume in 1 second [FEV1]). Results During accumulated follow-up of 1,469,518 person-years, there were 738 lung cancer diagnoses. A model incorporating all predictors had excellent discrimination (concordance (c)-statistic [95% CI] = 0.85 [0.82 to 0.87]). Internal validation suggested that the model will discriminate well when applied to new data (optimism-corrected c-statistic = 0.84). The full model, including FEV1, also had modestly superior discriminatory power than one that was designed solely on the basis of questionnaire variables (c-statistic = 0.84 [0.82 to 0.86]; optimism-corrected c-statistic = 0.83; pFEV1 = 3.4 × 10(-13)). The full model had better discrimination than standard lung cancer screening eligibility criteria (c-statistic = 0.66 [0.64 to 0.69]). Conclusion A risk prediction model that includes lung function has strong predictive ability, which could improve eligibility criteria for lung cancer screening programs.

    To estimate the impact on long term survival of functional status at six months after ischaemic stroke. Prospective cohort study. Settings Three cohorts: Oxfordshire community stroke project, Lothian stroke register, and the first international stroke trial (in the United Kingdom). 7710 patients with ischaemic stroke registered between 1981 and 2000 and followed up for a maximum of 19 years. Functional status at six months after stroke assessed with modified Rankin scale or "two simple questions." Mortality during follow-up. Survival analysis with Kaplan-Meier curves, log rank test, and Cox's regression model. In a combined analysis of all three cohorts, among patients who survived to assessment six months after the index stroke, the subsequent median length of survival among those independent in daily living and those dependent was 9.7 years (95% confidence interval 8.9 to 10.6) and 6.0 years (5.7 to 6.4), respectively. In a combined analysis of the Oxfordshire and Lothian cohorts, subsequent median survival fell progressively from 12.9 years (10.0 to 15.9) for patients with a Rankin score of 0-1 at six months after the stroke to 2.5 years (1.4 to 3.5) for patients with a Rankin score of 5. All previously stated differences in median survival were significant (log rank test P<0.001). The influence of functional outcome on survival remained significant (P<0.05) in each cohort after adjustment for relevant covariates (such as age, presence of atrial fibrillation, visible infarct on computed tomography, subtype of stroke) in a Cox's regression model. Functional status six months after an ischaemic stroke is associated with long term survival. Early interventions that reduce dependency at six months might have positive effects on long term survival.

Between March 2012 and June 2013, 56 patients were recruited for this study. Fifty-one patients met the inclusion criteria and were enrolled. Inclusion criteria were as follows: (1) age ≤65 years and (2) planned microsurgery or endovascular surgery for unruptured intracranial aneurysm. Exclusion criteria were as follows: (1) preoperative intelligence quotient <80 (n = 3); (2) initial modified Rankin scale ≥1 (n = 1); (3) loss to follow-up (n = 1). An auditory controlled continuous performance test (ACCPT), word-color test (WCT) and verbal learning test (VLT) were performed before and after (6 months) preventive surgery. ACCPT (attention), WCT (executive function) and VLT (learning and memory) scores did not change significantly between the pre- and postoperative evaluations. The ACCPT, WCT, total VLT scores (verbal learning) and delayed VLT scores (memory) did not differ significantly between patients undergoing microsurgery and those undergoing endovascular surgery. However, ACCPT, WCT and delayed VLT scores decreased postoperatively in patients with leukoaraiosis on preoperative FLAIR images (OR 9.899, p = 0.041; OR 11.421, p = 0.006; OR 2.952, p = 0.024, respectively). Preventive surgery for unruptured intracranial aneurysms did not affect attention, executive function, learning or memory. However, patients with leukoaraiosis on FLAIR images might be prone to deficits in attention, executive function and memory postoperatively, whereas learning might not be affected.

    Purpose: To quantitate changes in hearing function after radiotherapy for head-and-neck tumors. Methods and Materials: At the Department of Radiotherapy and Radiation Oncology, 32 patients were irradiated for head-and-neck tumors. Three-dimensional treatment planning was applied. Total tumor doses were 30.0-77.6 Gy, local doses to the inner ear (n = 64) ranged from 1.7 to 64.3 Gy. Audiometry was performed before the onset of radiotherapy (RT), at a tumor dose of 40 Gy or at the end of palliative treatment, at the end of curative RT, and 2-6 months post-RT. Assays applied were frequency-specific threshold measurements for air and bone conduction, measurements according to Weber and Rinne, tympanometry and assessment of the stapedius reflex. Results: Age and prior disease significantly decreased, whereas previous or concurrent alcohol consumption significantly increased hearing ability. A significant reduction in hearing ability during RT was found for high frequencies (at 40 Gy) and low frequencies (at end of RT), which persisted after RT. No differences were observed for air or bone conduction. None of the other assays displayed time- or dose-dependent changes. Dose-effect analyses revealed an ED50 (dose at which a 50% incidence is expected) for significant changes in hearing thresholds (15 dB) in the range of 20-25 Gy, with large confidence limits. Conclusions: Radiation effects on hearing ability were confined to threshold audiogram values, which started during the treatment without reversibility during 6 months postradiotherapy.

    To examine nasal airway function using a disease-specific quality-of-life survey instrument in subjects undergoing Le Fort I osteotomy without simultaneous rhinosurgical procedures. We conducted a prospective cohort study of nasal airway function in consecutive Le Fort I osteotomy patients, who had not received simultaneous rhinosurgical procedures, between 2007 and 2008 at Kaiser Permanente Oakland Medical Center. We administered the Nasal Obstruction Symptom Evaluation (NOSE) survey before and 3 months after surgery. Clinical and radiographic examinations were performed, and the relevant medical and demographic factors were analyzed. The initial study sample comprised 55 patients, of whom 5 were excluded. Of the remaining 50 patients (median age 21 years, 60% women), the maxilla was advanced (median 4 mm, interquartile range 3 to 5) with minimal vertical change. During the follow-up period (median 5.5 months), significant improvement was seen in the NOSE scores for the cohort, with a median decrease of 10 units (P = .0005). Patients with moderate nasal obstruction (preoperative NOSE score >25) had the greatest improvement (P < .001). Those with severe nasal obstruction (preoperative NOSE score >50) improved, however, this did not reach statistical significance (P < .0625). The NOSE scores worsened in 10 patients; of these, 6 had minimal change. However, 4 had significant worsening, with 2 having symptomatic complaints. No predictor variables were identified in this small subgroup; however, individual case analyses revealed 1 subject with postoperative turbinate inflammation on the side of maxillary segmentalization and 1 had nasal septal buckling. Our overall findings have suggested that nasal airway function improved after maxillary advancement and that subjects with greater preoperative NOSE scores (>25) were more likely to experience relief of nasal obstructive symptoms.

    This study evaluates predictors of recovery in walking ability, PADLs, and IADLs one year following hospital discharge for hip fracture. The sample consisted of 536 hip fracture patients aged 65 and older admitted from the community to one of seven Baltimore area hospitals between 1984 and 1986 and surviving one year post-hospital discharge. A large proportion of hip fracture patients do not regain pre-fracture PADL and IADL levels; most recovery in walking ability and ability to perform PADL and IADLs occurs by 6 months. Those who are older, have longer hospital stays, and are rehospitalized, exhibit poorer recovery, as do those displaying chronic or acute cognitive deficits and depressive symptomatology while hospitalized. Also, contact with one's social network following hospital discharge is associated with greater recovery. Findings point to the importance of psychosocial factors for recovery and suggest areas where hospital-based interventions and discharge planning efforts should focus.

    Recent literature has recognized a correlation with depression and poor self-reported functional outcome after orthopaedic procedures. However, the effect of depression on anterior cruciate ligament reconstruction (ACLR) outcome has never been studied. To quantify the incidence of major depressive disorder (MDD) and correlate depression symptoms with patient-rated knee function in patients undergoing ACLR. Cohort study; Level of evidence, 2. In this multicenter prospective cohort study, 64 consecutive adult patients undergoing primary ACLR were given the 16-item self-report Quick Inventory of Depressive Symptomatology (QIDS) to assess MDD symptoms preoperatively and at 6 weeks, 12 weeks, 24 weeks, and 1 year postoperatively. Lysholm and International Knee Documentation Committee (IKDC) subjective scores were obtained at the same time points to assess self-reported knee function. A QIDS score ≥6 served as a validated threshold for diagnosis of MDD. MDD and non-MDD group assignment was based on preoperative QIDS score. Student t test analysis was performed to compare ACLR outcomes between MDD and non-MDD patients. Correlation among QIDS, Lysholm, and IKDC scores was determined with Spearman r value. A total of 27 patients (42%) were categorized in the MDD group. At baseline, the MDD group reported mean Lysholm (50.8) and IKDC (43.7) scores that were significantly lower than those (64.9 and 57.0, respectively) reported by the non-MDD group (P < .05). Both cohorts showed similar and significant absolute improvement from baseline to 1 year postoperatively (MDD vs non-MDD, increase in mean Lysholm: +24.4 vs +23.5 [P = .63]; MDD vs non-MDD, increase in mean IKDC: +28.1 vs +32.3 [P = .21]). While Lysholm and IKDC scores improved in both groups, at 1-year follow-up, MDD patients reported significantly lower mean Lysholm (75.2 vs 88.4; P = .04) and mean IKDC (71.8 vs 89.3; P = .001) scores as compared with their non-MDD counterparts. In addition, a moderate inverse

    Maintaining patient adherence to disease modifying drugs in multiple sclerosis is a challenge, which can be improved by autoinjectors. The BETACONNECT® is a fully electronic autoinjector for the injection of interferon beta-1b (IFN beta-1b) automatically recording injections. The BETAEVAL study was a prospective, observational, cohort study over 24 weeks among patients with relapsing remitting multiple sclerosis or clinically isolated syndrome treated with IFN beta-1b in Germany using the BETACONNECT®. The primary aim was to investigate treatment adherence, secondary aims included assessing satisfaction and functional health status. Adherence was evaluated from injection data recorded by the device. Patient-related data were obtained from clinical examinations and patient questionnaires. Of the 151 patients enrolled, 143 were available for analysis. Thirty-four patients discontinued the study prematurely. 107/143 (74.8%) patients still used the BETACONNECT® at the end of the study. Injection data from the device at any visit was available for 107 patients. Among those, the percentage of adherent patients injecting ≥80% of doses and still participating in the study was 57.9% at week 24. 29% of patients prematurely stopped the study, 13.1% injected <80%. Among patients with BETACONNECT® data at the respective visit, the proportion of adherent patients was high over the entire study period (week 4: 81.1% [N = 95], week 12: 86.7% [N = 83], week 24: 80.5% [N = 77]). Participants (N = 143) indicated high satisfaction with the BETACONNECT®. At week 24, 98.0% of patients who completed the corresponding questionnaire (strongly) agreed that it was user-friendly, 81.2% felt confident in using it compared to their previous way and 85.5% preferred it to their previous way of injection. Injection-related pain was rated as mild to moderate at all follow-up visits. Whereas 17.2% of patients with corresponding questionnaire indicated using analgesics prior to

    Aims: (1) A prospective study to assess visual function measures and quality of life (QoL) in patients with wet age related macular degeneration (AMD) treated with photodynamic therapy (PDT). (2) To assess if PDT prevents severe visual loss (loss of six or more lines of distance visual acuity) in the treated eye. Methods: 48 of 51 recruited patients with predominantly classic subfoveal choroidal neovascularisation (CNV) secondary AMD who were treated with PDT were followed up for 1 year. Assessment included distance and near visual acuity, contrast sensitivity, vision related quality of life and fluorescein angiography. Photodynamic therapy using Visudyne was carried out according to standard protocol. Patients were followed up every 3 months and treatment repeated if there was significant leakage from CNV. Results: At the 12 month follow up, 71% (n = 34) of the patients lost less than three lines of best corrected distance visual acuity. Although there were significant decreases in some of the QoL items tested, patients were significantly less anxious and more independent outdoors at the 12 month follow up. Conclusion: This study is in keeping with published literature with PDT preventing severe visual loss in two thirds of treated patients with predominantly classic CNV. PMID:15377549

    Previous studies have investigated sensory recovery in patients with lumbar disc herniation using rather subjective methods. There have been no reports on changes of sensory function in patients suffering from a preoperative sensory deficit using quantitative sensory testing (QST). The aims of this prospective study were (1) to assess the recovery of preoperative sensory dysfunction after lumbar sequestrectomy and (2) to quantify the strength of relationship between a sensory deficit and the patient's quality of life. We applied the QST protocol of the German Research Network on Neuropathic Pain (DFNS) in fifty-two patients with a single lumbar disc herniation confirmed on MRI treated by lumbar sequestrectomy. Further evaluation included a detailed medical history, a physical examination, numeric rating scale for leg, EQ-5D questionnaire, and thermometer. Disc surgery resulted in a significant reduction of leg pain and a significant gain of quality of life. Thermal, mechanical, and vibration perception thresholds showed an obvious side-to-side difference preoperatively (p < 0.005). An early recovery of mechanical and vibration perception thresholds was detected, whereas cold perception needed more than 6 months to recover (p < 0.05). Quality of life was independent from perception thresholds, but correlated significantly with pain reduction. Our data clearly show that there is a subjective and quantifiable improvement in sensory dysfunction postoperatively. The current data suggest that a sensory dysfunction does not influence a patient's quality of life.

  13. Relationship between thyroid function and ICU mortality: a prospective observation study

    2012-01-01

    Introduction Although nonthyroidal illness syndrome is considered to be associated with adverse outcome in ICU patients, the performance of thyroid hormone levels in predicting clinical outcome in ICU patients is unimpressive. This study was conducted to assess the prognostic value of the complete thyroid indicators (free triiodothyronine (FT3), total triiodothyronine; free thyroxine, total thyroxine, thyroid-stimulating hormone and reverse triiodothyronine) in unselected ICU patients. Methods A total of 480 consecutive patients without known thyroid diseases were screened for eligibility and followed up during their ICU stay. We collected each patient's baseline characteristics, including the Acute Physiology and Chronic Health Evaluation II (APACHE II) score and thyroid hormone, N-terminal pro-brain natriuretic peptide (NT-proBNP) and C-reactive protein (CRP) levels. The primary outcome was ICU mortality. Potential predictors were analyzed for possible association with outcomes. We also evaluated the ability of thyroid hormones together with APACHE II score to predict ICU mortality by calculation of net reclassification improvement (NRI) and integrated discrimination improvement (IDI) indices. Results Among the thyroid hormone indicators, FT3 had the greatest power to predict ICU mortality, as suggested by the largest area under the curve (AUC) of 0.762 ± 0.028. The AUC for FT3 level was less than that for APACHE II score (0.829 ± 0.022) but greater than that for NT-proBNP level (0.724 ± 0.030) or CRP level (0.689 ± 0.030). Multiple regression analysis revealed that FT3 level (standardized β = -0.600, P = 0.001), APACHE II score (standardized β = 0.912, P < 0.001), NT-proBNP level (standardized β = 0.459, P = 0.017) and CRP level (standardized β = 0.367, P = 0.030) could independently predict primary outcome. The addition of FT3 level to APACHE II score gave an NRI of 54.29% (P < 0.001) and an IDI of 36.54% (P < 0.001). The level of FT3 was significantly

    Prospective remembering has been relatively underinvestigated in neurological patients. This paper describes a group study in which the prospective memory performance of 36 people with brain injury and 28 control participants is compared. We used a new instrument, the Cambridge Behaviour Prospective Memory Test (CBPMT) to assess prospective memory. This comprises 4 time-based and 4 event-based tasks. Participants were allowed to take notes to help them remember the tasks. The relationships between CBPMT scores, scores on formal tests and subjective reports on memory, attention and executive functioning were analyzed. The key findings were that (1) note-taking significantly benefited prospective memory performance, (2) significant relationships were found between scores on the prospective memory test and scores on tests of memory and executive functions, and (3) participants had more difficulty with the time-based than with the event-based prospective memory tasks. The results suggest that compensatory strategies improve prospective memory functioning; memory for content as well as attention and executive functioning processes are involved in prospective memory; and that time-based tasks are more difficult than event-based tasks because they place higher demands on inhibitory control mechanisms. Discussion focuses on the implications of these results for neuropsychological assessment and rehabilitation.

    Cognitive impairment has long been recognized as a co-morbidity or sequel to refractory epilepsy. This study was conducted to evaluate the degree and selectivity of involvement of memory, language and executive functions performance among patients with temporal (TLE) versus extratemporal epilepsy (ETLE). We prospectively enrolled adolescent and adult patients with medically refractory focal epilepsy, who had undergone pre-surgical evaluation. Language, memory and executive function assessment was done using Western Aphasia Battery, PGI memory scale and battery of four executive function tests (trail making test A & B, digit symbol test, Stroop Task and verbal fluency test), respectively. Among102 patients enrolled (TLE-59, ETLE-43), mean age of patients 23.0 4± 8.3 years, 83 (82%) had impairment of more than one cognitive domain and 21 (21%) had all three domains involved. Severely impaired memory scores were found in 8.6% patients with MTLE-HS, 8% of the rest of the patients with TLE and 7% patients with ETLE. The differences in the mean scores were also not found statistically significant (p=0.669). Naming impairment was the most common language abnormality, although all aphasia subscores were similar for the ETLE and TLE groups. Executive function impairment was the most common cognitive domain affected. Overall performance on executive function tests was found impaired in almost all patients of both groups without any significant inter-group difference, except on Trail-A test, which revealed better results in patients with mTLE-HS as compared to all other sub-groups. Our study shows that impairment of memory, language and executive function is common among patients with drug refractory epilepsy. The most prevalent impairment is in executive function. There is no significant difference in the degree, prevalence or selectivity of impairment in either of the three domains, between the TLE versus ETLE groups. Copyright © 2014 Elsevier B.V.

    Although lifestyle is associated with metabolic syndrome and cardiovascular diseases, there has been no sufficient evidence of lifestyles on incident chronic kidney disease (CKD). The purpose of this prospective cohort study is to investigate the effects of lifestyles on kidney function in healthy people. A total of 7473 healthy people were enrolled in this Saitama Cardiometabolic Disease and Organ Impairment Study, Japan. Data on alcohol consumption, exercise frequency, and sleep duration were collected. The outcome event was incident CKD or decrease in estimated glomerular filtration rate (eGFR) by >25% in 3 years. Subjects were classified into four groups according to body mass index and gender. Mean ± standard deviation of age was 38.8±10.5 years; eGFR, 78.1±15.2 ml/min/1.73 m2. In the male groups, multivariate logistic regression models showed that the outcome events were associated with a small amount of alcohol consumed (20 to 140 g of alcohol/week) (ref. more than 140 g of alcohol/week); non-obese male, adjusted odds ratio 1.366 (95% confidence interval, 1.086, 1.718); obese male (body mass index ≥25), 1.634 (1.160, 2.302); and with frequent exercise (twice a week or more) (ref. no exercise); non-obese male, 1.417 (1.144, 1.754); obese male, 1.842 (1.317, 2.577). Sleep duration was not associated with the outcome events. These findings suggest that, regardless of obesity, a small amount of alcohol consumed and high exercise frequency were associated with the increased risk of loss of kidney function in the male groups.

    Adaptation of skin barrier function and interleukin-1α (IL-1α) content in diapered and nondiapered skin are poorly characterized in newborns receiving standard skin care. In a monocentric, prospective pilot study 44 healthy, full-term neonates were randomly assigned to skin care with baby wipes (n = 21) or water-moistened washcloth (n = 23) at each diaper change. Transepidermal water loss (TEWL), skin hydration, skin-pH, IL-1α, and epidermal desquamation were measured on days 2, 14, and 28 postpartum. Microbiological colonization was evaluated at baseline and on day 28. Significantly lower TEWL was found on the buttock in the group using baby wipes compared to water. IL-1α and skin hydration significantly increased and pH decreased independent of skin care regimen. IL-1α was significantly higher in diapered skin compared to nondiapered skin. Although skin care with wipes seems to stabilize TEWL better than using water, the skin condition and microbiological colonization were comparable using both cleansing procedures. Increase of epidermal IL-1α may reflect postnatal skin barrier maturation. These data suggest that neither of the two cleansing procedures harms skin barrier maturation within the first four weeks postpartum. Longer observations on larger populations could provide more insight into postnatal skin barrier maturation.

    Introduction The fractures of the distal radius have always posed a unique challenge to the orthopaedic fraternity. The complex ligamentous and bony anatomy offers a wide variety of fractures to be dealt with around this zone. Over the years these injuries have become common especially in the elderly age group as well as the implants and surgical techniques have improved. Aim To assess the radiological and functional outcome after fixation of intra-articular dorsally displaced distal radius fractures with open reduction and volar Locking Compression Plate fixation (LCP). To study the complications occurring with this technique. Materials and Methods A prospective study was conducted in the Department of Orthopaedics at ARS Hospital, Tirupur, Tamil Nadu, from June 2015 to June 2016. A total of 20 skeletally mature patients with Lidstrom class 2D and 2E fresh closed distal radius fractures were enrolled in the study. All the patients underwent open reduction with locking compression plating with titanium LCPs using the volar approach. The patients were reviewed regularly at three, six, 12 and 24 weeks. Final assessment of radiographic fracture union was done and scored as per the ‘Radiographic Scoring System to Evaluate Union of Distal Radius Fractures {Radius Union Scoring System (RUSS)}’ and the functional assessment of the wrist was done using the Mayo wrist score. The final results were tabulated and calculated statistically using ‘frequency and proportions’ and ‘Chi-square tests’ were used to assess the test of association. Results Of the 20 patients reviewed, one patient had excellent Mayo wrist score, five had good scores, 12 had satisfactory and two patients had poor results. Seven patients had a RUSS score less than five points and four patients had RUSS score of five points, four patients had six points, two patients had seven points and three patients had eight points. One patient was noted to have dorsal collapse of the fracture during the

    Objectives: To study the effects of cognitive retraining and inpatient rehabilitation to study the effects of cognitive retraining and inpatient rehabilitation in patients with acquired brain injury (ABI). Design and Setting: This was a prospective follow-up study in a neurological rehabilitation department of quaternary research hospital. Patients and Methods: Thirty patients with ABI, mean age 36.43 years (standard deviation [SD] 12.6, range 18–60), mean duration of illness 77.87 days (SD 91.78, range 21–300 days) with cognitive, physical, and motor-sensory deficits underwent inpatient rehabilitation for minimum of 14 sessions over a period of 3 weeks. Nineteen patients (63%) reported in the follow-up of minimum 3 months after discharge. Type of ABI, cognitive status (using Montreal Cognitive assessment scale [MoCA] and cognitive Functional Independence Measure [Cog FIM]®), and functional status (motor FIM®) were noted at admission, discharge, and follow-up and scores were compared. Results: Patients received inpatient rehabilitation addressing cognitive and functional impairments. Baseline MoCA, motor FIM, and Cog FIM scores were 15.27 (SD = 7.2, range 3–30), 31.57 (SD = 15.6, range 12–63), and 23.47 (SD = 9.7, range 5–35), respectively. All the parameters improved significantly at the time of discharge (MoCA = 19.6 ± 7.4 range 3–30, motor FIM® = 61.33 ± 18.7 range 12–89, Cog FIM® =27.23 ± 8.10 range 9–35). Patients were discharged with home-based programs. Nineteen patients reported in follow-up and observed to have maintained cognition on MoCA (18.8 ± 6.8 range 6–27), significantly improved (P < 0.01) on Cog FIM® (28.0 ± 7.7 range 14–35) and motor FIM® =72.89 ± 16.2 range 40–96) as compare to discharge scores. Conclusions: Cognitive and functional outcomes improve significantly with dedicated and specialized inpatient rehabilitation in ABI patients, which is sustainable over a period. PMID:28694613

    Objective—To compare the value of current transthoracic echocardiographic systems and transoesophageal echocardiography for assessing left atrial appendage function and imaging thrombi.
Design—Single blind prospective study. Patients were first investigated by transthoracic echocardiography and thereafter by a second investigator using transoesophageal echocardiography. The feasibility of imaging the left atrial appendage, recording its velocities, and identifying thrombi within the appendage were determined by both methods.
Patients—117 consecutive patients with a stroke or transient neurological deficit.
Setting—Tertiary cardiac and neurological care centre.
Results—Imaging of the complete appendage was feasible in 75% of the patients by transthoracic echocardiography and in 95% by transoesophageal echocardiography. Both methods were concordant for the detection of thrombi in 10 cases. Transoesophageal echocardiography revealed two additional thrombi. In one of these patients, transthoracic echocardiography was not feasible and in the other the thrombus had been missed by transthoracic examination. In patients with adequate transthoracic echogenicity, the specificity and sensitivity of detecting left atrial appendage thrombi were 100% and 91%, respectively. Recording of left atrial appendage velocities by transthoracic echocardiography was feasible in 69% of cases. None of the patients with a velocity > 0.3 m/s had left atrial appendage thrombi. In the one patient in whom transthoracic echocardiographic evaluation missed a left atrial appendage thrombus, the peak emptying velocity of the left atrial appendage was 0.25 m/s.
Conclusions—A new generation echocardiographic system allows for the transthoracic detection of left atrial appendage thrombi and accurate determination of left atrial appendage function in most patients with a neurological deficit.

    This study aimed to identify and characterize homogeneous subgroups of individuals with distinct trajectories of physical functioning (PF) and to examine prognostic indicators of deterioration in PF in a highly heterogeneous population of older adults with joint pain and comorbidity. A prospective cohort study among 407 older adults with joint pain and comorbidity provided data over a period of 18 months, with 6 month time-intervals. We used latent class growth modelling (LCGM) to identify underlying subgroups (clusters) with distinct trajectories of PF. Next, we characterized these subgroups and applied multivariable logistic regression analysis to identify prognostic indicators for deterioration in PF. We measures PF with the RAND-36 PF subscale and several potential sociodemographic, physical and psychosocial prognostic indicators. LCGM identified three clusters. Cluster 1 'good PF' contained 140 participants with good baseline PF and small improvements over time. Cluster 2 'moderate PF' contained 130 participants with moderate baseline PF and deterioration over time. Cluster 3 'poor PF' contained 137 participants with poor baseline PF and deterioration over time. After backward selection, the final model that could best distinguish between improved participants (cluster 1) and deteriorated participants (cluster 2-3) included the following prognostic indicators: higher age, more depressive symptoms, less perceived self-efficacy and more activity avoidance. Older adults with joint pain and comorbidity either improved or deteriorated in PF over time. The prognostic model facilitates the classification of patients, the provision of more accurate information about prognosis and helps to narrow the focus to the high risk group of poor PF.

    Lower urinary tract symptoms are highly prevalent and a large proportion of these symptoms are known to be associated with a dysfunction of the afferent pathways. Diagnostic tools for an objective and reproducible assessment of afferent nerve function of the lower urinary tract are missing. Previous studies showed first feasibility results of sensory evoked potential recordings following electrical stimulation of the lower urinary tract in healthy subjects and patients. Nevertheless, a refinement of the methodology is necessary. This study is a prospective, randomized trial conducted at Balgrist University Hospital, Zürich, Switzerland. Ninety healthy subjects (forty females and fifty males) without lower urinary tract symptoms are planned to be included in the study. All subjects will undergo a screening visit (including standardized questionnaires, 3-day bladder diary, urinalysis, medical history taking, vital signs, physical examination, neuro-urological examination) followed by two measurement visits separated by an interval of 3 to 4 weeks. Electrical stimulations (0.5Hz-5Hz, bipolar, square wave, pulse width 1 ms) will be applied using a custom-made transurethral catheter at different locations of the lower urinary tract including bladder dome, trigone, proximal urethra, membranous urethra and distal urethra. Every subject will be randomly stimulated at one specific site of the lower urinary tract. Sensory evoked potentials (SEP) will be recorded using a 64-channel EEG cap. For an SEP segmental work-up we will place additional electrodes on the scalp (Cpz) and above the spine (C2 and L1). Visit two and three will be conducted identically for reliability assessment. The measurement of lower urinary tract SEPs elicited by electrical stimulation at different locations of the lower urinary tract has the potential to serve as a neurophysiological biomarker for lower urinary tract afferent nerve function in patients with lower urinary tract symptoms or disorders

    The objective of this study is to report the initial results of a prospective trial assessing instrumental deglutition function in nasopharynx and oropharynx cancers after radio or chemoradiotherapy using intensity-modulated radiotherapy (IMRT). IMRT was delivered aiming to spare the swallowing organ at risk (SWOARs) for Stage II-IV naso- and oropharynx cancer. Objective instrumental assessment included videofluoroscopy (VFS), fiberoptic endoscopic evaluation of swallowing (FEES) and oro-pharyngeal-oesophageal scintigraphy (OPES) at baseline and at 1 month after radiotherapy. Dysphagia parameter scores were calculated at each exam after liquid (L) and semi-liquid (SL) bolus intake: pre-deglutition penetration, aspiration, pharyngeal transit time (PTT) and hypopharyngeal retention index (HPRI). Overall, 20 patients (6 nasophaynx and 14 oropharynx) completed treatment and instrumental assessment after 1 month. Comparison between pre- and post-treatment HPRI score values showed a significant worsening in both FEES-L (p = 0.021) and SL (p = 0.02) and at VFS-L (p = 0.008) and SL (p = 0.005). Moreover, a relationship between HPRI worsening at FEES-L and FEES-SL (p = 0.005) as well as at VFS-L and VFS-SL (p < 0.001) was observed. PTT was not significantly affected by radiotherapy (p > 0.2). Only a few patients experienced pre-deglutition penetration (1 patient with base of tongue cancer at FEES-L and SL) and aspiration (1 patient with nasopharynx cancer at OPES-L and FEES-SL) after radiotherapy. Our early results showed that IMRT-SWOARs sparing caused a significant increase in the post-deglutition HPRI score. Longer follow-up will be necessary to evaluate if the increase of HPRI is related to a high risk of developing late aspiration.

    Potential pathways from childhood sexual abuse (CSA) to negative self-schemas to subsequent dissociative symptoms and low global self-esteem were examined in a prospective longitudinal study of 160 ethnically diverse youth with confirmed CSA histories. Participants were interviewed at the time of abuse discovery, when they were 8-15 years of age, and again 1- and 6- years later. Abuse-specific indicators of stigmatization, in particular the combination of shame and self-blame, more than general self-blame attributions for everyday events, explained which youth with CSA histories experienced more dissociative symptoms and clinically significant levels of dissociation. Abuse-specific stigmatization was found to operate as a prospective mechanism for subsequent dissociative symptoms but not self-esteem. PMID:20390797

    The influence of pre-existing radiographic osteoarthritis on the functional outcome of elderly patientents with displaced intracapsular fractures of the femoral neck treated by hemiarthroplasty is unclear. We prospectively examined the impact of pre-existing osteoarthritis on the functional outcome of 126 elderly patients with displaced intracapsular fracture of the femoral neck treated by hemiarthroplasty. The mean age of the cohort was 82.7 years. At 12 months, we observed no statistically significant differences in the Harris hip score (p = 0.545), the timed up and go test (p = 0.298), the Tinetti test (p = 0.381) or the Barthel Index (p = 0.094) between patients with Kellgren and Lawrence grades 3 or 4 osteoarthritis, and patients with grades 0 to 2 changes. Furthermore, there were no differences in complication or revision rates. Our findings challenge the hypothesis that pre-existing osteoarthritis is a contraindication to hemiarthroplasty in elderly patients with femoral neck fracture.

    In patients with aortic stenosis (AS) functional mitral regurgitation (FMR) is frequent and is attributed to left ventricular (LV) remodelling and to aortic gradient. However, the association of these variables with mitral effective regurgitant orifice (ERO) is still unknown. We prospectively enrolled patients with aortic valve thickness and aortic velocities >2.5 m/s. We measured the LV diastolic (LVD) and systolic volumes (Simpson's method) and ejection fraction (EF) and longitudinal shortening (S-DTI), early, and late (A-DTI) lengthening velocities. The aortic valve area (AVA) and mean gradient (MG) were measured. FMR was considered in the absence of any alteration of mitral leaflet. ERO and regurgitant volume were measured by means of a proximal velocity surface area method method. One hundred and seventy-two patients formed the study population (mean age 76 ± 8 years; 50% female, EF 57 ± 14%, AVA 1.00 ± 0.4 cm(2)). Sixty-three per cent of patients had FMR (ERO range: 0.02 0.32 cm(2)). ERO was significantly associated with LVD (rho = 0.34; P = 0.0001), EF (r(s) = -0.35: P = 0.0001), and S-DTI (r = -0.57; P = 0.0001), A-DTI (rho = -0.47; P = 0.0001). In the subgroup of patients with a preserved EF (LVD <75 mL/m(2) and EF >55%), S-DTI, and A-DTI were the variables with the more powerful association with ERO (r(s) = -0.49 P = 0.0001 and r(s) = -0.40 P = 0.0001, respectively). In the overall population there was a non-significant negative association between the degree of AS and ERO (MG: r(s) = -0.08 P = 0.2 and AVA: r(s) = -0.08 P = 0.2). In AS patients, the LV function is a main determinant of FMR even if EF is preserved. The association between ERO and valvular gradient is complex but tended to be negative.

    The primary physiologic function of platelets is to facilitate hemostasisby aggregation. Volatile anesthetics have been reported to decrease platelet aggregation in vivo and in vitro. The aim of this study was to investigate the hematologic effectsof the anesthetics isoflurane, sevoflurane, and desflurane on hemoglobin (Hb), hematocrit (Hct), platelet count, activated partial thromboplastin time (aPTT), prothrombin time (PT), international normalized ratio (INR), and platelet aggregation after minor surgery. Patients aged 20 to 60 years who were scheduled to undergominor surgery and American Society of Anesthesiologists physical status P1 or P2 (healthy or mild systemic disease) were randomized to 1 of 3 groups: 1 minimum alveolar concentration (MAC) of isoflurane, sevoflurane, or desflurane. None of the patients received premedication. Anesthesia was induced using IV thiopental 5 to 6 mg/kg, fentanyl 1 to 2 μg/kg, and vecuronium 0.1 mg/kg, and maintained with 1 MAC of isoflurane, sevoflurane, or desflurane in 66% nitrous oxide and 33% oxygen. Vecuronium 0.03 mg/kg was given when necessary for muscle relaxation. All patients were monitored throughout surgery; isotonic saline was given at a rate of 5 mL/kg · h. Hematologic studies were performed preoperatively, 15 minutes after intubation, and 1 hour after the end of surgery. Platelet aggregation tests were performed in a laboratory using a platelet function analyzer (PFA), collagen/epinephrine PFA test cartridges, collagen/adenosine diphosphate PFA test cartridges, and PFA trigger solution. This prospective, randomized, single-blind, in vivo study was conducted at Gevher Nesibe Teaching Hospital, Erciyes University, Kayseri, Turkey. Thirty patients (15 men, 15 women) were randomized to the 3 treatment groups (each, n = 10). Hb, Hct, platelet count, aPTT, PT, and INR were statistically similar between all 3 groups. The measured parameters were not significantly different between the isoflurane and desflurane

    Excess thyroid hormone is associated with increased bone loss and fracture risk in older women, but few data exist for men. We sought to determine if thyroid function is independently associated with bone loss and fracture risk in older men. Data were analyzed from the Osteoporotic Fractures in Men (MrOS) study, a cohort of community-dwelling U.S. men aged 65 years and older. Using a case-cohort design, fasting baseline serum archived at -80°C was assayed for thyroid-stimulating hormone (thyrotropin) (TSH) and free thyroxine (FT4) in 397 men with confirmed nonspine fracture, including 157 hip fractures, and 1420 randomly selected men without fracture. TSH and FT4 were analyzed as continuous variables and as thyroid function categories (subclinical hyperthyroid, euthyroid, and subclinical hypothyroid). Hip dual-energy X-ray absorptiometry (DXA) (Hologic QDR4500) was measured at baseline and after a mean follow-up of 4.6 years. Incident nonspine fractures were centrally adjudicated. Bone loss was evaluated with multivariate regression methods and fractures risk was evaluated using hazard models that accounted for the case-cohort sampling, adjusted for age, clinic-site, body mass index (BMI), race, physical activity, corticosteroid use, smoking, alcohol intake, and thyroid medication use. In fully adjusted analyses, TSH was not associated with risk of nonspine fracture (relative hazard [RH] 0.92 per SD decrease in TSH; 95% confidence interval [CI], 0.74-1.14), but was significantly associated with risk of hip fracture (RH 1.31; 95% CI, 1.01-1.71), which persisted among normal range TSH values (RH 1.21; 95% CI, 1.00-1.47). There was no association between TSH or FT4 and bone loss, and fracture risk did not differ significantly by thyroid function category. We conclude that although neither TSH nor FT4 are associated with bone loss, lower serum TSH may be associated with an increased risk of hip fractures in older men.

    One-third of patients with fecal incontinence (FI) do not have any anal dysfunction. The aim was to characterize patients with FI with normal anal function compared with patients with anal weakness. The general characteristics and data of anal manometry, endosonography, and defecography of patients who were evaluated for FI at a single institution from 2005 to 2015 were prospectively assessed. Fecal incontinence was defined by the Cleveland Clinic Incontinence Score (CCIS) >4. Anal weakness was defined by one or more of the three following parameters: <25 mmHg at the upper part of the anal canal, <26 mmHg at the lower part of the anal canal, and <60 mmHg for the mean squeeze pressure. A total of 439 patients with FI were included (152 with normal anal function/287 with anal weakness). Severe constipation (Kess score ≥21) was predominant in patients with normal anal function (44/151 vs 50/284, respectively; p = 0.0054). Fecal incontinence with normal anal function was significantly associated with lower age (>63 years; odds ratio [OR] = 0.29), higher weight (>65 kg; OR = 1.69), fecal urgency (OR = 1.58), less severe FI score (CCIS score >10; OR = 0.52), higher abdominal pressure (>36 mmHg; OR = 2.15), and paradoxical puborectal contraction (OR = 2.07) in a multivariate analysis model. Fecal incontinence with normal anal function is a specific phenotype that involves distal constipation and may be an early stage of FI with anal weakness. Physicians should adapt their management to focus on the treatment of constipation. © 2016 John Wiley & Sons Ltd.

    Purpose: To evaluate the effects of cranial radiotherapy (RT) on cognitive function in patients with supratentorial low-grade glioma. Methods and Materials: Twenty adult patients with supratentorial low-grade glioma were treated with 50.4 Gy (10 patients) or 64.8 Gy (10 patients) localized RT. The patients then were evaluated with an extensive battery of psychometric tests at baseline (before RT) and at approximately 18-month intervals for as long as 5 years after completing RT. To allow patients to serve as their own controls, cognitive performance was evaluated as change in scores over time. All patients underwent at least two evaluations. Results: Baseline test scores were below average compared with age-specific norms. At the second evaluation, the groups' mean test scores were higher than their initial performances on all psychometric measures, although the improvement was not statistically significant. No changes in cognitive performance were seen during the evaluation period when test scores were analyzed by age, treatment, tumor location, tumor type, or extent of resection. Conclusions: Cognitive function was stable after RT in these patients evaluated prospectively during 3 years of follow-up. Slight improvements in some cognitive areas are consistent with practice effects attributable to increased familiarity with test procedures and content.

    The study sought to examine the role of frontal lobe functioning in focal prospective memory (PM) performance and its relation to PM deficit in older adults. PM and working memory (WM) differences were studied in younger aged (n = 21), older aged (n = 20), and frontal injury (n = 14) groups. An event-based focal PM task was employed and three measures of WM were administered. The younger aged group differed from the other two groups in showing significantly higher scores on PM and on one of the WM measures, but there were no differences at a statistically significant level between the older aged group and the frontal injury groups on any of the memory measures. There were, however, some differences in correlations with a WM measure between groups. It is concluded that there are similarities and differences in the deficits in PM between older adults and patients with frontal lobe injury on focal as well as nonfocal PM tasks.

    To evaluate the prospective use of the thermography diagnostic system in assessing sexual function in patients with erectile dysfunction (ED). Thermographs were taken on 14 subjects in a clinical trial conducted at Tan Tock Seng Hospital. After a thorough clinical interview with a standardized questionnaire, patients were scanned for baseline temperature profile before being given an oral dose of sildenafil 100 mg. Subjects were scanned again in the same setting an hour later. If so desired, subjects were given visual stimulation and were allowed minimum direct stimulation, excluding the penis, to elicit erection. Temperature profiles were analyzed using the thermography analysis software in the VarioCAM camera. Three representative cases are presented to illustrate the potential for using the Infrared thermography (IR) diagnostic system in differentiating psychogenic ED. IR was able to capture a significant difference in blood flow to the corpus cavernosum. Subjects with psychogenic ED have higher surface temperatures (34.3 degrees C +/- 0.71 in the flaccid state and 35.3 degrees C +/- 0.2 during erection) compared to subjects with organic ED (33.64 degrees C +/- 0.4 in flaccid and 33.55 degrees C +/- 0.91 during erection). The difference in surface temperature between flaccid and erected states in subjects with organic ED was not significant. The proposed diagnostic test based on IR has tremendous clinical potential in differentiating psychogenic ED from organic ED. IR could potentially be a portable, noninvasive and convenient adjunct in the diagnosis and management of ED.

    Background. The evolution of neurocognitive performance in aviremic human immunodeficiency virus (HIV)–positive patients treated with <3 antiretrovirals is unknown. Methods. We prospectively included aviremic (≥1 year) HIV-positive patients, without concomitant major neurocognitive confounders, currently receiving boosted lopinavir or darunavir as monotherapy (n = 67) or triple antiretroviral therapy (ART) (n = 67) for ≥1 year. We evaluated neurocognitive function (7 domains) at baseline and after 1 year. We performed analysis of covariance to evaluate if 1 additional year of exposure to monotherapy compared with triple ART had an effect on Global Deficit Score (GDS) changes after adjustment for potential confounders. We also compared the evolution of neurocognitive performance and impairment rates. Results. Intention-to-treat analysis showed that monotherapy did not influence 1-year GDS change after adjustment for significant confounders (age, ethnicity, duration of therapy, hepatitis C virus status, and HOMA-IR index); the adjusted effect was −0.04 (95% confidence interval, −.14 to .05; P = .38). Neurocognitive stability was observed with monotherapy and triple therapy (GDS crude mean change, −0.09 [95% confidence interval, −.16 to −.01] vs −0.08 [−.14 to −.02]), after 1 year of follow-up, similar proportions of patients changed neurocognitive status from impaired to unimpaired (monotherapy, 4 of 18 [22.2%]; triple therapy, 4 of 19 [21.1%]; P = .91) and vice versa (monotherapy, 5 of 44 [10.2%] and triple therapy, 3 of 45 [6.3%]; P = .48). Similar results were observed in an on-treatment analysis and with use of clinical ratings instead of GDS changes. Conclusions. The number of antiretrovirals included in the ART regimen does not seem to influence the evolution of neurocognitive function in HIV-infected patients with suppressed plasma viremia. PMID:25114032

    The best method of preventing hypoparathyroidism after thyroidectomy is to keep parathyroid glands in situ. However, hypoparathyroidism still regularly occurs with the existing parathyroid classification system, and the incidence of permanent hypoparathyroidism has not been reduced. We created a novel system for classifying parathyroid glands that can guide parathyroid preservation in thyroidectomy.We prospectively observed parathyroid glands using the new system in 218 neck surgeries, compared with 132 under the traditional system from January 2014 to September 2015 at a single clinic center. Briefly, we classified parathyroid glands as follows: Type A, no dependency on the thyroid; B1, partial blood supply from the thyroid but retains adequate blood supply after removal of the thyroid; B2, partial blood supply from the thyroid and becomes devascularized after the removal of the thyroid; B3, blood supply mostly from the thyroid; and C, blood supply completely dependent on the thyroid. The classifications were used to decide between in situ preservation or auto-transplantation.The most common type of parathyroid gland was type B1 (53.77%), followed by type A (20.89%), which are the perfect categories for in situ preservation. Type B2 (17.52%) and type B3 (1.21%) have a chance to be kept in situ. For type C (6.61%), in situ preservation is impossible. When in-situ preservation is ruled out, parathyroid auto-transplantation is an alternative, with partial or total gland tissue, depending on the classification and the surgeon's discretion. Among the patients who were classified under the new system, 43.6% presented with transient hypoparathyroidism (symptoms lasting ≤6 months) after surgery, versus 42.4% in the old system, which was not a significant difference. However, permanent hypothyroidism (symptoms lasting >6 months) was not detected in the applied group, but in 3.0% of patients in the nonapplied group (P = 0.01).Our novel functional nomenclature system

    Bipolar disorder is a lifelong illness requiring lifelong pharmacotherapy. Therefore besides symptomatic remission, achievement of full work-related functioning and restoration of quality of life is a priority during successful treatment. The present prospective, observational, non-intervention study focused on investigating the effect of lamotrigine therapy on the quality of life and work-related function of bipolar patients in outpatient care. 969 bipolar or schizoaffective outpatients participated in the study who previously did not receive lamotrigine therapy. Our present phase-prophylactic study was a prospective, observational, non-intervention study with a six-month follow-up. Evaluations took place at baseline and at months 1, 2, 3 and 6. Patients were followed with a Clinical Global Impression-Severity (CGI-S) and Clinical Global Impression-Improvement (CGI-I). Changes in work-related function was evaluated using Social Adjustment Scale (SAS), while quality of life was assessed with the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) scale. SAS scoreds showed a consistent decrease in the overall sample and in all CGI-S initial groups reflecting the improvement of work-related function during the six months of the follow-up. Q-LES-Q values in the whole sample and in all initial CGI-S groups showed a steady increase indicating a continuous increase in quality of life during the study. Our results indicate that during long-term prophylactic lamotrigine therapy the work function and quality of life of bipolar patients shows a significant improvement, therefore lamotrigine provides a possibility for full functional remission and restoration of quality of life.

    It is a well-known fact, that in most of the psychiatric diseases problems can break out on the field of sexual life as well, which frequently occurs particularly in depression. The problems can be even worse, because of the side effects of the antidepressants causing sexual dysfunction. Nowadays there are some new antidepressants, which have more favourable side effect profiles. The aim of this study was to follow up the occuring side effects during mirtazapine treatment with special regard to incidence of sexual problems. Altogether 102 outpatients (44 men, 58 women) were recruited to this prospective, observational, non-interventional study, who were suffering from depression and had stable partner, permanent sexual life and who signed the informed consent. The screening was followed by three visits, when the 17-HAMD, CGI and 9-BDI scales were used. The change of sexual life was monitored by a self- completing questionnaire. Both the depression rating scales and the CGI have shown a significant mood improvement. From monitoring the changes in sexual life it turned out, that patients reported sexual problems much rarer as they had done it at the beginning of the study (screening: 93.2%, one month later 61%, three months later 27.1%, at the end of the study only 24.6%) Patients were evaluating their sexual life better and better during the study, and parallel to this, frequency of sexual intercourse was also increased. On the basis of the results it can be established, that mirtazapine is an effective tool for even those depressed patients who suffer from sexual dysfunction. Together with curing the depression and improving the sexual life mirtazapine can also help to restore the good quality of life.

    Remifentanil is an opiod with fast onset of action and short acting, and its use in short-duration procedures has increased in the last few years. Bradycardia and asystole are among the side effects reported. The objective of this study was to evaluate the effects of this drug in cardiac conduction and refractory period in human beings. A prospective study with 16 patients, ages 18 to 65, both genders, ASA I to III, undergoing elective intracardiac electrophysiological study, was undertaken. Patients with disorders of the sinoatrial node and those with severe cardiac blocks were excluded. In the laboratory of electrophysiology, patients were sedated with midazolam (0.03 mg.kg-1) after 5 minutes the degree of sedation and degree of pain, systolic and diastolic blood pressure, heart rate and respiratory rate, and oxygen saturation were evaluated. The electrophysiologist evaluated cardiac conduction (duration of the QRS complex, and AA, AH, HV, and PA intervals), duration of sinoatrial node recovery, and cardiac refractory period (refractory period of the right atrium, right ventricle, and atrioventricular node). After the initial measurements, remifentanil was administered (bolus of 0.5 microg.kg-1 + infusion of 0.05 microg.kg-1.min-1) and, after 20 minutes, the same parameters were evaluated. There was a reduction in systolic and diastolic blood pressure (p = 0.0001) between M0 and M1, and significant differences in respiratory rate and oxygen saturation, which were not statistically significant. The atrium-His interval (p = 0.006), recovery time of the sinoatrial node (p = 0.0004), refractory period of the right atrium (p = 0.001), and refractory period of the sinoatrial node (p = 0.0001) were all increased; however, there were no differences in heart rate between M0 and M1. Remifentanil changes cardiac electrophysiological parameters and, in doses higher than the ones used in this study, can cause sinus bradycardia, asystole, and conduction defects.

    To obtain the proof of concept of a novel therapy for Alzheimer's disease (AD), we conducted two prospective studies with hemodialysis patients who had amyloid β protein (Aβ) removed from their blood three times a week. One major pathological change in the brain associated with AD is Aβ deposition, mainly 40 amino acids Aβ1-40 and 42 amino acids Aβ1-42. Impaired Aβ clearance is proposed to be one cause of increased Aβ in the AD brain. Thus, we hypothesized that an extracorporeal removal system of Aβ from the blood may remove brain Aβ and be a useful therapeutic strategy for AD. In the first prospective study, plasma Aβ levels and the cognitive function of 30 hemodialysis patients (65-76 years old) were evaluated at baseline as well as 18 or 36 months after. Although plasma Aβ1-40 levels either decreased or remained unchanged, levels of Aβ1-42 either remained unchanged or increased at the second time point. Mini-Mental State Examination scores of most subjects increased or were maintained at the second time point. Aβ1-40 influx into the blood correlated with MMSE at the second time point. In the second prospective study, five patients (51-84 years old) with renal failure were evaluated before and after the initiation of hemodialysis. Plasma Aβ levels decreased, while cognitive function improved after initiating blood Aβ removal. Therefore, long-term hemodialysis, which effectively removes blood Aβ, might alter Aβ influx and help maintain cognitive function.

    A comparison of offspring of parents with bipolar disorder (OBD) and offspring of parents with no mental disorder (ONMD) showed that parents' neuroticism was associated with internalizing and externalizing problems among their children. The present study examined whether parents' neuroticism predicted poor interpersonal functioning among offspring 10 years later and whether the problems observed in middle childhood mediated the association between parents' neuroticism and offspring functioning. When offspring were in middle childhood, parents completed the revised NEO Personality Inventory and rated the child's behavior on the Child Behavior Checklist. Ten years later, 65 OBD and 59 ONMD completed interviews assessing mental disorders and interpersonal and noninterpersonal functioning. High neuroticism and low agreeableness in parents predicted poor interpersonal functioning in their offspring in late adolescence-early adulthood. The offspring's externalizing and internalizing problems in middle childhood partially mediated the association between parents' personality and offspring interpersonal functioning. Moreover, the association between parents' neuroticism and offspring internalizing problems was stronger among the OBD than the ONMD. Overall, the results suggested an intergenerational transmission of risk whereby high neuroticism and low agreeableness in parents were associated with behavioral problems among offspring in middle childhood that, in turn, predicted poor interpersonal functioning 10 years later.

    As survival rates have risen for children with malignant primary brain tumors, so has the concern that many survivors have significant permanent cognitive deficits. Cranial irradiation (CRT) has been implicated as the major cause for cognitive dysfunction. To clarify the etiology, incidence, and severity of intellectual compromise in children with brain tumors after CRT, a prospective study was undertaken comparing the neuropsychological outcome in 18 consecutive children with malignant brain tumors treated with CRT to outcome in 14 children harboring brain tumors in similar sites in the nervous system who had not received CRT. Children with cortical or subcortical brain tumors were not eligible for study. Neuropsychological testing was performed after surgery prior to radiotherapy, after radiotherapy, and at 1- and 2-year intervals thereafter. Children who had received CRT had a mean full-scale intelligence quotient (FSIQ) of 105 at diagnosis which fell to 91 by Year 2. Similar declines were noted in their performance intelligence quotient (IQ) and verbal IQ. After CRT, patients demonstrated a statistically significant decline from baseline in FSIQ (p less than 0.02) and verbal IQ (p less than 0.04). Children who had not received CRT did not demonstrate a fall in any cognitive parameter over time. The decline between baseline testing and testing performed at Year 2 in patients who had CRT was inversely correlated with age (p less than 0.02), as younger children demonstrated the greatest loss of intelligence. Children less than 7 years of age at diagnosis had a mean decline in FSIQ of 25 points 2 years posttreatment. No other clinical parameter correlated with the overall IQ or decline in IQ. After CRT, children demonstrated a wide range of dysfunction including deficits in fine motor, visual-motor, and visual-spatial skills and memory difficulties.

    Purpose: To evaluate the effects of radiation therapy (RT) on neurocognitive function in patients with nasopharyngeal carcinoma (NPC). Methods and Materials: Thirty patients with NPC treated with intensity-modulated RT were included. Dose-volume histograms of the temporal lobes were obtained in every patient. Neurocognitive tests were administered individually to each patient 1 day before initiation of RT and at least 12 months after completion of RT. Cognitive functioning status was evaluated as change in scores over time. Results: Among the total of 30 patients, 23 patients (76.7%) had significantly lower post-RT cognitive functioning scores compared with their pre-RT scores (p = 0.033). The cognitive functioning scores had significantly declined in the domains of short-term memory, language abilities, and list-generating fluency (p = 0.020, 0.023, and 0.001, respectively). Compared with patients with a mean dose to the temporal lobes of 36 Gy or less, patients with a mean dose of greater than 36 Gy had a significantly greater reduction in cognitive functioning scores (p = 0.017). Patients in whom V60 of the temporal lobes (i.e., the percentage of the temporal lobe volume that had received >60 Gy) was greater than 10% also had a greater reduction in cognitive functioning scores than those in whom V60 was 10% or less (p = 0.039). Conclusions: The results of our study indicated that RT could have deleterious effects on cognitive function in patients with NPC. Efforts should be made to reduce the radiation dose and irradiated volume of temporal lobes without compromising the coverage of target volume.

    (1) To examine the impact of demographic and acute injury-related variables on functional recovery and life satisfaction after severe traumatic brain injury (sTBI) and (2) to test whether postinjury functioning, postconcussive symptoms, emotional state, and functional improvement are related to life satisfaction. Prospective national multicenter study. Level 1 trauma centers in Norway. 163 adults with sTBI. Functional recovery between 3 and 12 months postinjury measured with Glasgow Outcome Scale Extended, Rivermead Postconcussion Symptoms Questionnaire, Hospital Anxiety and Depression Scale, and satisfaction with life situation. 60% of cases experienced functional improvement from 3 to 12 months postinjury. Multivariate logistic regression analysis revealed that discharge to a rehabilitation department from acute care (odds ratio [OR] = 2.14; P < .05) and fewer days with artificial ventilation (OR = 1.04; P < .05) were significantly related to improvement. At 12 months postinjury, 85% were independent in daily activities. Most participants (63%) were satisfied with their life situation. Regression analysis revealed that older age (>65 years), low education, better functional outcome, and the absence of depressive and postconcussion symptoms were significant (P < .05) predictors of life satisfaction. Functional improvement was significantly associated with emotional state but not to life satisfaction. Following sTBI, approximately two-thirds of survivors improve between 3 and 12 months postinjury and are satisfied with their life. Direct discharge from acute care to specialized rehabilitation appears to increase functional recovery.

    This study examined the relation between sexual functions of women in prepregnancy (before conception) and during pregnancy and the postpartum period. This study was conducted on 59 healthy pregnant women. Participants were followed from the eighth week of gestation to 6 months after delivery. Sexual function during pregnancy and the postpartum period was shown to have a significant linear correlation with prepregnancy sexuality. There was no relation between pregnancy and postpartum sexuality. All of the participants who had prepregnancy sexual dysfunction continued to experience it during pregnancy, and the majority of them had a significant level of sexual dysfunction in the postpartum period. Our results showed that prepregnancy sexuality plays an important role in maintaining sexuality during pregnancy and the postpartum period.

    Although many studies have demonstrated effects of prenatal alcohol exposure (PAE) on physical, cognitive, and behavioral development in children, few have focused on the long term effects on adults. In this study, data are presented on adaptive function and entry into adult roles in a community sample of young adults with PAE. The expectation was that prenatally exposed adults would show lower adaptive functioning and more difficulty with entry into adult roles than the non-exposed control group and that these effects would be related to the severity of PAE effects. The predominantly African-American, low income sample included adults with a wide range of prenatal exposure (n = 123) as well as control groups for socioeconomic (SES) (n =5 9) and disability (n = 54) status. The mothers of the alcohol-exposed and SES-control group participants were recruited before birth and offspring have been followed up periodically. The disability control group was recruited in adolescence. The adults were interviewed about adaptive function in day-to-day life and adult role entry. Collateral adults who were well-acquainted with each participant were interviewed concerning adaptive function. Results showed that adults who were dysmorphic and/or cognitively affected by PAE had difficulty with adaptive function and entry into adult roles. Males showing cognitive effects with no physical effects were the most severely affected. Results for exposed adults not showing physical or cognitive effects were similar to or more positive than those of the control group for most outcomes. PAE has long-term effects on adaptive outcomes in early adulthood. Additional research should focus on possible interventions at this transition and on factors contributing to the adjustment of the exposed, but unaffected participants. Copyright © 2015 Elsevier Inc.

    To examine how visual impairment affects physical and cognitive function in old age. A longitudinal population-based prospective cohort study. General practitioner offices at six study centers in Germany. They were observed every 1.5 years over four waves. Individuals aged 77-101 at follow-up Wave 2 (N = 2,394). Physical and cognitive function were assessed using an adapted scale that had been previously developed, and visual impairment was rated on a Likert scale (none, mild, severe or profound). Adjusting for sociodemographic factors and comorbidity, linear fixed-effects regression showed that the onset of severe visual impairment was associated with a decline in physical function score in the total sample (β = -0.15, P = .01) and in women (β = -.15, P = .03). Moreover, the onset of severe visual impairment was associated with decline in cognitive function score in the total sample (β = -0.38, P < .001) and in women (β = -0.38, P < .001) and men (β = -0.37, P = .001). Visual impairment affects physical and cognitive function in old age. Interventional strategies to postpone visual impairment may contribute to maintaining physical and cognitive function. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    Prospective randomized study. To investigate differences in physical functional outcome in patients with radiculopathy due to cervical disc disease, after structured physiotherapy alone (consisting of neck-specific exercises with a cognitive-behavioral approach) versus after anterior cervical decompression and fusion (ACDF) followed by the same structured physiotherapy program. No earlier studies have evaluated the effectiveness of a structured physiotherapy program or postoperative physical rehabilitation after ACDF for patients with magnetic resonance imaging-verified nerve compression due to cervical disc disease. Our prospective randomized study included 63 patients with radiculopathy and magnetic resonance imaging-verified nerve root compression, who were randomized to receive either ACDF in combination with physiotherapy or physiotherapy alone. For 49 of these patients, an independent examiner measured functional outcomes, including active range of neck motion, neck muscle endurance, and hand-related functioning before treatment and at 3-, 6-, 12-, and 24-month follow-ups. There were no significant differences between the 2 treatment alternatives in any of the measurements performed (P = 0.17-0.91). Both groups showed improvements over time in neck muscle endurance (P ≤ 0.01), manual dexterity (P ≤ 0.03), and right-handgrip strength (P = 0.01). Compared with a structured physiotherapy program alone, ACDF followed by physiotherapy did not result in additional improvements in neck active range of motion, neck muscle endurance, or hand-related function in patients with radiculopathy. We suggest that a structured physiotherapy program should precede a decision for ACDF intervention in patients with radiculopathy, to reduce the need for surgery. 2.

Participants were 144 partnered Airmen assessed immediately before and during a one-year high-risk deployment to Iraq. Results showed an overall high frequency of partner communication during deployment. High relationship distress at predeployment predicted lower frequency of communication during deployment. Changes in relationship distress from before deployment to during deployment independently predicted frequency of communication, above and beyond predeployment distress levels. Level of relationship distress and depression during deployment independently predicted service members' ratings of impact on duty performance. © 2013 American Association for Marriage and Family Therapy.

    Computer navigation in total knee arthroplasty produces better component alignment than conventional techniques. Different navigation systems exist. We undertook a prospective, randomized study comparing 2 navigations systems (Stryker Full Navigation and Stryker Articular Surface Mounted [ASM] navigation systems). Three-dimensional component alignment (Perth computed tomographic knee protocol) and function at 1 year (Knee Society Scores) were assessed. Forty patients participated (20 fully navigated and 20 ASM-navigated total knee arthroplasties). Cohorts were well matched according to sex, age, and body mass index. No statistically significant difference was seen in any parameter of 3-dimensional component alignment or function between cohorts. Operative time for the ASM cohort was significantly less than the fully navigated cohort (P = .001). Both systems performed equally well, and therefore, surgeon preference should determine which system is used.

    Objective: The purpose of this study was to explore the accuracy of elevated liver function values, age, gender, pancreatitis and cholecystitis as predictors of common bile duct stones (CBDS). Methods: All patients operated on for gallstone disease over a period of 3 years in a Swedish county of 302 564 citizens were registered prospectively. Intraoperative cholangiography (IOC) was used to detect CBDS. Results: A total of 1171 patients were registered; 95% of these patients underwent IOC. Common bile duct stones were found in 42% of patients with elevated liver function values, 20% of patients with a history of pancreatitis and 9% of patients with cholecystitis. The presence of CBDS was significantly predicted by elevated liver function values, but not by age, gender, history of acute pancreatitis or cholecystitis. A total of 93% of patients with normal liver function tests had a normal IOC. The best agreement between elevated liver function values and CBDS was seen in patients undergoing elective surgery without a history of acute pancreatitis or cholecystitis. Conclusions: Although alkaline phosphatase (ALP) and bilirubin levels represented the most reliable predictors of CBDS, false positive and false negative values were common, especially in patients with a history of cholecystitis or pancreatitis, which indicates that other mechanisms were responsible for elevated liver function values in these patients.

    Background: Reactive oxygen species (ROSS) play an important role in the pathogenesis of asthma, and oxidative stress contributes to the initiation and worsening of inflammatory respiratory disorders (eg, asthma). Thus, antioxidant drugs may have a role in reducing or preventing damage in asthma. Objective: The aim of the study was to investigate the antioxidant effect of zafirlukast, a leukotriene receptor antagonist, in asthma. Methods: This prospective, controlled, in vitro study was conducted at KingKhalid University Hospital, Riyadh, Saudi Arabia. The generation of ROSS by polymorphonuclear neutrophil leukocytes (PMNs) in patients with mild to moderate asthma (forced expiratory volume in 1 second [FEVI], >70% of the predicted value) and healthy volunteers was assessed using chemiluminescence (CL) with phorbol 12-myristate 13-acetate (PMA) and opsonized zymosan (OPZ) in the presence of different concentrations of zafirlukast (1.25-60 μg/mL). The xanthine/xanthine oxidase (X-XOD) reaction was used to test the scavenging effect of the drug. Results: Six asthmatic patients (4 women, 2 men; mean age, 30.8 years; meanFEVI, 82.5% of the predicted value) and 8 healthy volunteers (4 women, 4 men; mean age, 28.8 years) were enrolled. A dose-dependent inhibition of the CL response was observed in both groups. However, patients with asthma required higher concentrations of zafirlukast to achieve an inhibitory effect similar to that in healthy controls. This difference was significant at concentrations of 20 to 60 μg/mL (all, P ≤ 0.05). When PMNs were challenged with OPZ, inhibition was also dose dependent in controls at all concentrations (all, P ≤ 0.05), but the inhibitory effect was not significant in the asthmatic patients at any concentration. The difference in the inhibitory effect between the 2 groups was significant at 30, 40, and 60 μg/mL (P < 0.02, <0.01, and <0.01, respectively). The mean (SEM) viability of the PMNs in the healthy controls was

    Objective: To study role of ankle foot orthosis (AFO) in improving locomotion and functional recovery after stroke. Setting: Neurological Rehabilitation Department of a university research tertiary hospital. Patients and Methods: AFO and activity based rehabilitation. Main Outcome Measures: Distance (meters) covered during the 6-minute walk test (6MWT) and speed (meter/second) during the 10-meter walk test. Functional abilities assessed using Functional Independence Measure (FIM®). Results: Twenty-six patients (21 male) with stroke (mean duration 196.7 days, range 45–360 days) and mean age of 41.6 years (range 18–65 years, standard deviation [SD] 12.5) were included. Fourteen had right hemiplegia. The mean length of stay in the unit was 26.5 days (range 18–45 days, SD 5.5). All patients had equinus deformity with spastic foot drop and were provided with AFO. Walking endurance with 6MWT was 90 m on admission (without AFO). At discharge, it improved to 174 m with AFO and 121 m without AFOs (P < 0.001-with and without AFO at discharge). Walking speed improved from 0.4 m/s (admission) to 0.51 m/s with AFO, P = 0.004 and 0.45 m/s without AFO, P = 0.015) at discharge. Nine patients (34.6%) had clinically important difference-minimal clinically important difference (>0.16 m/s speed gain; >50 m endurance gain) at discharge. The mean FIM® score on admission was 84.3 ± 18.6. At discharge FIM® improved to 101.9 ± 13.7 (P < 0.001). Conclusions: Use of AFOs improve gait parameters significantly in only one-third stroke patients in the study when combined with activity-based inpatient-rehabilitation. PMID:27695234

    Background End-stage chronic kidney disease is associated with striking excesses of cardiovascular mortality, but it is uncertain to what extent renal function is related to risk of subsequent coronary heart disease (CHD) in apparently healthy adults. This study aims to quantify the association of markers of renal function with CHD risk in essentially general populations. Methods and Findings Estimated glomerular filtration rate (eGFR) was calculated using standard prediction equations based on serum creatinine measurements made in 2,007 patients diagnosed with nonfatal myocardial infarction or coronary death during follow-up and in 3,869 people without CHD in the Reykjavik population-based cohort of 18,569 individuals. There were small and nonsignificant odds ratios (ORs) for CHD risk over most of the range in eGFR, except in the lowest category of the lowest fifth (corresponding to values of <60 ml/min/1.73m2), in which the OR was 1.33 (95% confidence interval 1.01–1.75) after adjustment for several established cardiovascular risk factors. Findings from the Reykjavik study were reinforced by a meta-analysis of six previous reports (identified in electronic and other databases) involving a total of 4,720 incident CHD cases (including Reykjavik), which yielded a combined risk ratio of 1.41 (95% confidence interval 1.19–1.68) in individuals with baseline eGFR less than 60 ml/min/1.73m2 compared with those with higher values. Conclusions Although there are no strong associations between lower-than-average eGFR and CHD risk in apparently healthy adults over most of the range in renal function, there may be a moderate increase in CHD risk associated with very low eGFR (i.e., renal dysfunction) in the general population. These findings could have implications for the further understanding of CHD and targeting cardioprotective interventions. PMID:17803353

  20. Multidimensional associative factors for improvement in pain, function, and working capacity after rehabilitation of whiplash associated disorder: a prognostic, prospective outcome study

    2014-01-01

    Background Whiplash associated disorders (WAD) have dramatic consequences for individual and public health. Risk factors for better and worse outcomes are important to optimize management. This study aimed to determine short- and mid-term associative co-factors of neck pain relief, improved physical functioning, and improved working capacity (dependent variables) in patients suffering from whiplash associated disorder who participated in a standardized, inpatient pain management program. Methods Naturalistic, observational, prospective cohort study. Outcome was measured by standardized assessment instruments. Co-factors covered sociodemographics, comorbidities, social participation, affective health, and coping abilities. Stepwise, multivariate linear regression analysis was performed at discharge and at the 6-month follow-up. Results All regression models explained high proportions of variance (53.3% – 72.1%). The corresponding baseline level was significantly associated with a change in every dependent variable (explained variances: 11.4%-56.7%). Pain relief significantly depended on improved function and vice-versa (3.4%-14.8%). Improved ability to decrease pain was associated with pain relief at discharge (9.6%). Functional improvement was associated with decreased catastrophizing (19.4%) at discharge and decreased depression (20.5%) at the 6 month follow-up. Conclusions Pain relief, improved physical function and working capacity were associated with each other. Improved coping (catastrophizing and ability to decrease pain) and reduced depression may act as important predictors for pain relief and improved function. These findings offer toe-holds for optimized therapy of chronic WAD. PMID:24739588

    Changes in cognitive function induced by physical activity have been proposed as a mechanism for the link between physical activity and academic performance. The aim of this study was to investigate if executive function mediated the prospective relations between indices of physical activity and academic performance in a sample of 10-year-old Norwegian children. The study included 1,129 children participating in the Active Smarter Kids (ASK) trial, followed over 7 months. Structural equation modeling (SEM) with a latent variable of executive function (measuring inhibition, working memory, and cognitive flexibility) was used in the analyses. Predictors were objectively measured physical activity, time spent sedentary, aerobic fitness, and motor skills. Outcomes were performance on national tests of numeracy, reading, and English (as a second language). Generally, indices of physical activity did not predict executive function and academic performance. A modest mediation effect of executive function was observed for the relation between motor skills and academic performance.

    The consequences of minor trauma involving a head injury (MT-HI) in independent older adults are largely unknown. This study assessed the impact of a head injury on the functional outcomes six months post-injury in older adults who sustained a minor trauma. This multicenter prospective cohort study in eight sites included patients who were aged 65 years or older, previously independent, presenting to the emergency department (ED) for a minor trauma, and discharged within 48 hours. To assess the functional decline, we used a validated test: the Older Americans' Resources and Services Scale. The cognitive function of study patients was also evaluated. Finally, we explored the influence of a concomitant injury on the functional decline in the MT-HI group. All 926 eligible patients were included in the analyses: 344 MT-HI patients and 582 minor trauma without head injury. After six months, the functional decline was similar in both groups: 10.8% and 11.9%, respectively (RR=0.79 [95% CI: 0.55-1.14]). The proportion of patients with mild cognitive disabilities was also similar: 21.7% and 22.8%, respectively (RR=0.91 [95% CI: 0.71-1.18]). Furthermore, for the group of patients with a MT-HI, the functional outcome was not statistically different with or without the presence of a co-injury (RR=1.35 [95% CI: 0.71-2.59]). This study did not demonstrate that the occurrence of a MT-HI is associated with a worse functional or cognitive prognosis than other minor injuries without a head injury in an elderly population, six months after injury.

    Background A reduction in adiposity may be associated with an improvement in insulin sensitivity and β-cell function as well as cardiovascular disease (CVD) risk factors; however, few studies have investigated these associations in a longitudinal setting. Methods To investigate these associations over a 1-year period, we conducted an observational analysis of 196 Japanese subjects with obesity in the Saku Control Obesity Program. We investigated the relations between changes in adiposity (body mass index [BMI], waist circumference, subcutaneous fat area [SFAT], and visceral fat area [VFAT]) and changes in HbA1c, fasting plasma glucose (FPG), insulin sensitivity index (ISI), the homeostasis model assessment β cell function (HOMA-β), lipids, and blood pressure. Results All adiposity changes were positively associated with HbA1c and FPG changes. Reductions in BMI and VFAT were associated with HOMA-β reduction. Reductions in all adiposity measures were associated with an improvement in the ISI. Changes in most adiposity measures were positively associated with changes in blood pressure and lipid levels, except for LDL. Conclusion The present findings provide additional supportive evidence indicating that a reduction in adiposity may lead to an improvement in insulin sensitivity and the reduction of CVD risk factors in obese individuals.

    Robot-enhanced therapies are increasingly being used to improve gross motor performance in patients with cerebral palsy. To evaluate gross motor function, activity and participation in patients with bilateral spastic cerebral palsy (BS-CP) after Robot-enhanced repetitive treadmill therapy (ROBERT) in a prospective, controlled cohort study. Participants trained for 30-60 min in each of 12 sessions within a three-week-period. Changes in Gross Motor Function Measure (GMFM 66) scores, standardized walking distance, self-selected and maximum walking speed (ICF domain "Activity"), and Canadian Occupational Performance Measure (COPM; "Participation") were measured. Outcome measures were assessed three weeks in advance (V1), the day before (V2) as well as the day after, and 8 weeks after ROBERT (V3 + V4). 18 patients with BS-CP participated; age 11.5 (mean, range: 5.0-21.8) years, body weight 36.4 (15.0-72.0) kg. GMFCS levels I-IV were: n = 4; 5; 8; 1. There was no significant difference comparing V1 and V2. GMFM 66 (total +2.5 points, Dimension D +3.8 and E +3.2) and COPM (Performance +2.1 points, Satisfaction +1.8 points) showed statistically significant improvements for V3 or V4 compared to V1 or V2 representing clinically meaningful effect sizes. Age, GMFCS level, and repeated ROBERT blocks correlated negatively with GMFM improvement, but not with COPM improvement. Following ROBERT, this prospective controlled cohort study showed significant and clinically meaningful improvements of function in ICF domains of "activity" and "participation" in patients with BS-CP. Further assessment in a larger cohort is necessary to allow more specific definition of factors that influence responsiveness to ROBERT program. Copyright © 2014. Published by Elsevier Ltd.

    The objectives of the study were as follows: (1) to investigate whether the predictive validity of a previously developed back pain prediction rule could be improved; (2) to determine if the rule can be shortened without loss of predictive validity; (3) to compare the rule with the physician's judgment; (4) to assess, in a different population, its 2-year predictive validity; and (5) to evaluate the clinical applicability of the rule in a first-line care setting. One thousand two hundred and sixty-two participants were enrolled in the study (participation: 91%) before a medical consultation for nonspecific back pain in a large emergency room and were followed up for 2 years (follow-up: 92.5%). The effects of adding new items and deleting any one of the original items were evaluated. The predictions by the rule and the physicians were compared with the 2-year actual functional limitations (measured with the Roland-Morris Disability Questionnaire). Although the final prediction rule included only five items (feeling everything is an effort, trouble getting breath, hot/cold spells, numbness/tingling in parts of body, and pain in heart/chest), its predictive validity was greater than that of the original 17-item version and was superior to the physician's prediction. The rule was easily applied. A five-item clinical prediction rule of long-term back-related functional limitations could help first-line care physicians to concentrate the clinical attention on patients at higher risk.

    Introduction Cervical spondylotic myelo-radiculopathy is a form of spinal cord dysfunction syndrome and usually accompanies age related degeneration of the spine. Aim To determine the functional outcome of anterior cervical discectomy with fusion and plating in single level degenerative cervical disc prolapse. Materials and Methods A total of 20 patients diagnosed with degenerative single level cervical disc prolapse who presented to the Department of Orthopaedic Surgery, Justice KS Hegde Charitable Hospital, Mangalore from the period of November 2012 to May 2014 were enrolled in the study. Complete clinical and radiological evaluation of the patients was done. A trial of conservative management was tried in all these patients for a period of two months. They were taken up for surgery only when conservative management had failed. Scoring of neck function before the surgery was done as per the Modified Japanese Orthopaedic Association (MJOA) score. All patients underwent anterior cervical discectomy and fusion (ACDF) with tricortical iliac crest bone grafting. Fixation was performed with titanium locking cervical plates. All patients were reviewed at 6 weeks and 6 months postoperatively. Assessment of neck function was done as per the MJOA scoring during all the reviews. Radiographic assessment was also done during all the reviews. The complications noted were documented. The statistical analysis was done using percentages; the arithmetic mean was calculated using SPSS software (version 16.0). Results Amongst the 20 patients included in the study, 1 patient died postoperatively due to oesophageal rupture. of the remaining 19 patients reviewed and followed up, all of them had improvement of symptoms and were reported to be in the ‘mild category’ as per the MJOA score. One patient developed dysphonia, in the immediate postoperative period due to recurrent laryngeal nerve palsy which recovered in a period of three months postoperative. Conclusion Single level

    2012-01-01

    Background Little is known about the long-term outcomes for patients with schizophrenia who fail to achieve symptomatic remission. This post-hoc analysis of a 3-year study compared the costs of mental health services and functional outcomes between individuals with schizophrenia who met or did not meet cross-sectional symptom remission at study enrollment. Methods This post-hoc analysis used data from a large, 3-year prospective, non-interventional observational study of individuals treated for schizophrenia in the United States conducted between July 1997 and September 2003. At study enrollment, individuals were classified as non-remitted or remitted using the Schizophrenia Working Group Definition of symptom remission (8 core symptoms rated as mild or less). Mental health service use was measured using medical records. Costs were based on the sites’ medical information systems. Functional outcomes were measured with multiple patient-reported measures and the clinician-rated Quality of Life Scale (QLS). Symptoms were measured using the Positive and Negative Syndrome Scale (PANSS). Outcomes for non-remitted and remitted patients were compared over time using mixed effects models for repeated measures or generalized estimating equations after adjusting for multiple baseline characteristics. Results At enrollment, most of the 2,284 study participants (76.1%) did not meet remission criteria. Non-remitted patients had significantly higher PANSS total scores at baseline, a lower likelihood of being Caucasian, a higher likelihood of hospitalization in the previous year, and a greater likelihood of a substance use diagnosis (all p < 0.05). Total mental health costs were significantly higher for non-remitted patients over the 3-year study (p = 0.008). Non-remitted patients were significantly more likely to be victims of crime, exhibit violent behavior, require emergency services, and lack paid employment during the 3-year study (all p < 0.05).

    A prospective analysis was used to test whether respiratory impairment or the presence of respiratory symptoms predicts 5-year cigarette smoking cessation in a sample of 1,118 U.S. white, male, underground coal miners. Miners were examined in 1977 and re-examined in 1982 by NIOSH, and all miners with test abnormalities were so informed by letter. Respiratory impairment was measured by an index of airways obstruction combining the spirometric measures of Forced Vital Capacity (FVC) and Forced Expiratory Volume in 1 sec (FEV1). Bronchitis symptoms were measured by an index that combined chronic cough (3+ months/year) and chronic phlegm (3 + months/year). Among these coal miners, the presence of chronic respiratory symptoms initially was inversely associated with cigarette smoking cessation. Respiratory impairment, however, was positively associated with cigarette smoking cessation but did not reach statistical significance.

    In contrast to the multitude of investigations regarding aesthetic changes in nasal surgery, few data are available concerning nasal function. This is especially important for cleft patients with a compromised nasal respiration.In this prospective study, 68 cleft patients, who underwent nasal surgery, were evaluated concerning aesthetic and respiratory outcome. To assess nasal respiration, active anterior rhinomanometry, rhinoresistometry, and acoustic rhinometry were performed preoperatively and 6 months postoperatively (without and with nasal decongestion, according to international standards). For analyzing the changes in aesthetic parameters, photographs from 3 directions, which were taken preoperatively and at least 6 months postoperatively, were compared. Thus, 57 angles and relations of lines were created out of 54 anthropometric points. The Wilcoxon test was used to compare preoperative and postoperative data (P < 0.05). Regarding aesthetic outcome, a significant improvement in many parameters was seen. The noses postoperatively proved to be significantly narrower and more symmetric and showed a better projection.Although analysis of functional respiratory data showed a significant increase in nasal volume, no change in nasal airflow and hydraulic diameter could be found.Whereas aesthetic improvement of the cleft nose is a goal, which can be achieved regularly, nasal respiration still seems to be a challenge in cleft patients. This study highlights the necessity of taking functional data to learn more about the effects of surgery. Objective methods to assess nasal respiratory function are important for planning and performing nasal surgery and are a means of quality control.

    To examine the associations between the functioning of patients with severe traumatic brain injury (TBI), and their relatives' coping style and quality of life across 12 months post-injury. Prospective, population-based cohort study assessing 188 patients with severe TBI (Abbreviated Injury Scale of the head region [HAIS] score >3), and their relatives, 3, 6 and 12 months post-injury. Data were drawn from a larger national study run in Switzerland (2007-2011). Patient assessment: Glasgow Coma Outcome Scale Extended (GOSE), Patient Competency Rating Scale for Neurorehabilitation (PCRS-NR). Relative assessment: Health-Related Quality of Life (HRQoL; 12-item short form health survey [SF-12]), Coping Inventory for Stressful Situations (CISS). Mixed linear models were run separately for ages >50 and ≤50 (i.e. bimodal distribution). Patients' GOSE score was associated with relatives' reported mental SF-12 scores across age (ps < 0.01). Relatives' CISS was associated with patients' PCRS score (age > 50 years): Total and cognitive functioning decreased as emotion-oriented coping increased (ps = 0.01), while interpersonal functioning increased as task-oriented coping increased (p = 0.01) and decreased as avoidance-oriented coping increased (p = 0.02). Patients' functioning and relatives' mental HRQoL and coping strategies are associated with each other.

    Subacromial impingement syndrome (SIS) is one of the most frequent shoulder pathologies. Initial treatment is conservative. Subacromial injection of drugs achieves a high concentration at the pathologic site with less drug use and fewer systemic side effects. Glucocorticoids are most frequently injected. One concern with steroid use is the wide array of potential systemic and local complications. Nonsteroidal anti-inflammatory drugs (NSAIDs) are also peripherally acting and can be used locally. Although intraarticular (IA) use of NSAIDs is common in orthopedic practice, it is mostly restricted to the knee joint. Reports of local NSAID for joint pathologies are relatively rare. This study compared the efficacy of single-dose subacromial injections of betamethasone and lornoxicam for treatment of SIS. Subacromial injections of either 7.0 mg betamethasone or 8 mg lornoxicam were received by 70 patients with mean age 53 (46-68) years. Treatment outcome was assessed with Constant-Murley and UCLA questionnaires before injection and at 2‑, 4‑, and 6‑week follow-ups. The change in outcome scores compared to pretreatment was higher in the steroid group at all follow-ups (p < 0.001). Patients in the steroid group showed a significant improvement at all follow-ups compared to pretreatment (p <0.001) and previous follow-ups (p <0.05) at all times. Patients in the lornoxicam group showed a significant functional improvement in week 2 (p <0.001), which was not evident in the following weeks (p >0.05). Although functional recovery halted after week 2, outcome scores remained significantly higher than the pretreatment values at all weeks (p <0.001). Although a single subacromial lornoxicam injection provides rapid functional recovery, which partially extends into the intermediate term, its results are inferior to betamethasone and it may be an alternative only in patients where corticosteroids are contraindicated.

    2012-01-01

    Introduction One of the therapeutic essentials in severe sepsis and septic shock is an adequate fluid replacement to restore and maintain circulating plasma volume, improve organ perfusion and nutritive microcirculatory flow. The type of solution to be used as a fluid replacement remains under discussion. The aim of the study was to evaluate the effects of clinically used fluid replacement solutions on renal function and inflammatory response. Methods A total of 23 anesthetized and ventilated female German Landrace pigs were investigated over 19 hours using a two-hit model that combined hemorrhagic and septic shock. The septic shock was induced using an Escherichia coli laden clot placed into the abdominal cavity. Infusions of 6% hydroxyethylstarch 130/0.42 in acetate (6% HES 130), 4% gelatin in acetate (4% gelatin) and 10% hydroxyethylstarch 200/0.5 in saline (10% HES200) compared to Ringer's acetate (RAc) were used for fluid replacement to maintain a central venous pressure of 12 mmHg. Ringer's acetate was also used in the sham-treated group (SHAM). Results At study end the cardiac output (10% HES200 143 ± 48 ml/kgBW; 6% HES130 171 ± 47 ml/kgBW; RAc 137 ± 32 ml/kgBW; 4% gelatin 160 ± 42 ml/kgBW), as well as mean arterial pressure did not differ between groups. N-acetyl-beta-D-glucosamidase was significantly higher in the hydroxyethylstarch 200 (157 ± 115 U/g creatinine; P < 0.05) group compared to hydroxyethylstarch 130 (24 ± 9 U/g creatinine), Ringer's acetate (2 ± 3 U/g creatinine) and SHAM (21 ± 15 U/g creatinine) at the study's end. Creatinine significantly increased by 87 ± 84 percent of baseline in the 10% HES200 group compared to RAc and 6% HES130. We demonstrated in the histology of the kidneys a significant increase in osmotic-nephrosis like lesions for 4% gelatin compared to RAc, 6% HES130 and SHAM. Urine output was lowest in the 10% HES200 and 4% gelatin group, however not significantly. Interleukin(IL)-6 levels were significantly elevated in

    Diabetes mellitus is a known risk factor for polyneuropathy, but the role of pre-diabetes and metabolic syndrome remains unclear. We aimed to investigate the role of these factors in a community-dwelling middle-aged and elderly population. 1256 participants of the population-based Rotterdam Study (mean age 70.0, 54.5% females) were screened for polyneuropathy with a questionnaire, neurological examination and nerve conduction studies. Data on type 2 diabetes and components of metabolic syndrome were also collected. Logistic regression was used to investigate associations of diabetes, pre-diabetes and metabolic syndrome and its separate components with polyneuropathy. Linear regression was used to investigate associations with nerve conduction parameters in participants without polyneuropathy. Diabetes was associated with polyneuropathy (OR 3.01, 95% CI 1.60 to 5.65), while impaired fasting glucose was not (OR 1.55, 95% CI 0.70 to 3.44). Metabolic syndrome was associated with polyneuropathy (OR 1.92, 95% CI 1.09 to 3.38), with a stronger association when more components of the syndrome were present. Analysing separate components of metabolic syndrome revealed associations for elevated waist circumference (OR 2.84, 95% CI 1.35 to 5.99) and elevated triglycerides (OR 2.01, 95% CI 1.11 to 3.62). Similar associations were found after excluding participants with diabetes. In participants without polyneuropathy, metabolic syndrome associated with lower sural sensory nerve action potential amplitudes. Metabolic syndrome, abdominal obesity and dyslipidaemia, are strongly associated with polyneuropathy, irrespective of the presence of diabetes. Metabolic syndrome also associates with impaired nerve function in people without polyneuropathy. Our study therefore suggests that cardiometabolic disturbances have an impact on peripheral nerve function that extends beyond clinically manifest disease.

    Decision-making deficits are thought to play an important role in the development and persistence of substance use disorders. Individual differences in decision-making abilities and their underlying neurocircuitry may, therefore, constitute an important predictor for the course of substance use and the development of substance use disorders. Here, we investigate the predictive value of decision making and neural mechanisms underlying decision making for future cannabis use and problem severity in a sample of heavy cannabis users. Brain activity during a monetary decision-making task (Iowa gambling task) was compared between 32 heavy cannabis users and 41 matched non-using controls using functional magnetic resonance imaging. In addition, within the group of heavy cannabis users, associations were examined between task-related brain activations, cannabis use and cannabis use-related problems at baseline, and change in cannabis use and problem severity after a 6-month follow-up. Despite normal task performance, heavy cannabis users compared with controls showed higher activation during wins in core areas associated with decision making. Moreover, within the group of heavy cannabis users, win-related activity and activity anticipating loss outcomes in areas generally involved in executive functions predicted change in cannabis use after 6 months. These findings are consistent with previous studies and point to abnormal processing of motivational information in heavy cannabis users. A new finding is that individuals who are biased toward immediate rewards have a higher probability of increasing drug use, highlighting the importance of the relative balance between motivational processes and regulatory executive processes in the development of substance use disorders.

    Abstract Biochemical or clinical changes of hyperandrogenism are important elements of polycystic ovary syndrome (PCOS). There is currently no consensus on the definition and diagnostic criteria of hyperandrogenism in PCOS. The aim of this study was to investigate the complex symptoms of hyperandrogenic disorders and the correlations between metabolism and hyperandrogenism in patients with PCOS from an outpatient reproductive medicine clinic in China. We conducted a case control study of 125 PCOS patients and 130 controls to evaluate differences in body mass index (BMI), total testosterone (TT), modified Ferriman-Gallwey hirsutism score, sex hormone binding globulin (SHBG), homeostasis model assessment-estimated insulin resistance (HOMA-IR) and free androgen index (FAI) between PCOS patients and controls and subgroups of PCOS. The prevalence of acne and hirsutism did not differ significantly between the hyperandrogenic and non-hyperandrogenic subgroup. Patients with signs of hyperandrogenism had significantly higher BMI (P < 0.05), but differences in TT, SHBG, FAI and waist/hip ratio were insignificant. The odds ratio of overweight was calculated for all PCOS patients. Our results suggest that PCOS patients with high BMI tend to have functional disorders of androgen excess; therefore, BMI may be a strong predictor of hyperandrogenism in PCOS. PMID:27526961

    Right ventricular (RV) function alterations are invariably present in all patients after tetralogy of Fallot (TOF) repair. Unlike the developed world where most of the patients with TOF are corrected in infancy, average age of presentation and thus surgery for these patients in the developing world may be higher. We aimed to study the correlation between RV function parameters such as tricuspid annular peak systolic excursion (TAPSE), fractional area change (FAC), and tricuspid annular peak systolic velocity (S') with early outcome variables after intracardiac repair for TOF. Fifty patients with a preoperative diagnosis of tetralogy of Fallot scheduled for corrective surgery were included in this single-center, prospective observational study. A preoperative transthoracic echocardiogram was performed to measure RV function parameters (FAC0, TAPSE0, S'0). Transthoracic echocardiography was repeated postoperatively to measure FAC1, TAPSE1, S'1 (day 1) and FAC2, TAPSE2, and S'2 (day 3). The relationship between preoperative and postoperative RV function parameters with in-hospital mortality, duration of mechanical ventilation, and intensive care unit stay was studied. The median age of patients was 6 years (range 1-14 years). Multiple stepwise logistic regression analysis showed RV FAC as best predictor of clinical outcome. Area under the receiver operating characteristic curve for postoperative RV function parameters, that is, FAC, TAPSE, and S' to predict early or delayed recovery was 0.944, 0.875, and 0.655, respectively. Among the RV function parameters studied, RV FAC best predicted the early outcome variables after TOF repair, followed by TAPSE while lateral tricuspid annular velocity S' being the least predictive. © 2016, Wiley Periodicals, Inc.

    Introduction Uterine leiomyomas are the most common benign gynecologic tumors. To date laparoscopy myomectomy is the gold standard for treatment of symptomatic fibroids in reproductive-aged women. Detailed counseling about the effects of this procedure on postoperative sexuality and quality of life is important in these patients. However, available data on these subjects are limited and contradictory. The aim of this study was to assess sexual function and quality of life in premenopausal women undergoing laparoscopic myomectomy for symptomatic uterine fibroids. Material and Methods All premenopausal women who underwent laparoscopic myomectomy for symptomatic fibroids between April 2012 and August 2014 at a tertiary university center were enrolled in this prospective observational cohort study. Sexual function and quality of life were assessed for the pre- and postoperative (six months post-operatively) state using two validated questionnaires, the Female Sexual Function Index (FSFI) and the European Quality of Life Five-Dimension Scale (EQ-5D). Results Ninety-five of the 115 (83%) eligible patients completed the study. Overall a significant improvement in quality of life and sexual function was observed in the study cohort: Median FSFI (28 (18.7–35.2)) and EQ-5D scores (1 (0.61–1) after laparoscopic myomectomy were significantly higher than preoperative scores (21.2 (5.2–33.5); 0.9 (0.2–1); p ≤ 0.01). The number, position and localization of the largest fibroids were not correlated with pre- or postoperative sexual function or quality of life. Conclusion Laparoscopic myomectomy might have positive short-term effects on postoperative quality of life and sexual function in premenopausal women suffering from symptomatic fibroids.

    Malnutrition is common in patients with hip fractures, and elderly patients with hip fractures lose functional independence and often fail to recover previous functional status. The aim of this study was to determine whether pre-fracture nutritional status predicts functional status of patients with hip fracture at discharge from acute hospitals. In the present multicenter prospective cohort study, pre-fracture nutritional status was assessed using the Mini Nutritional Assessment Short-Form (MNA-SF). At discharge from acute hospitals, functional status was evaluated using a functional independent measurement instrument (FIM). Subsequently, multiple regression analyses were performed using FIM as the dependent variable and MNA-SF as the independent variable. Among the 204 patients analyzed in the present study, the mean length of hospital stay was 26.2 ± 12.6 days, and according to MNA-SF assessments, 51 (25.0%) patients were malnourished, 98 (48.0%) were at risk of malnutrition, and 55 (27.0%) were well-nourished before fracture. At discharge, FIM scores were higher in patients who were well-nourished than in those who were malnourished or were at risk of malnutrition (p < 0.01). After adjustment for confounding factors, multiple regression analyses showed that MNA-SF was a significant independent predictor for FIM at discharge (well-nourished vs. malnourished, β = -0.86, p < 0.01). Pre-fracture nutritional status was a significant independent predictor for functional status at discharge during the acute phase, warranting early assessment of nutritional status and early intervention for successful postoperative rehabilitation.

    Objective Sarcopaenia and physical function impairment may have a greater effect on survival than other clinical characteristics, including multimorbidity. In this study, we evaluated the impact of sarcopaenia on all-cause mortality and the interaction among muscle loss, physical function impairment and multimorbidity on mortality risk over 10 years in older community-dwellers. Design Prospective cohort study. Setting Population-based study. Participants All persons aged 80+ years living in the community in the Sirente geographic area (L'Aquila, Italy) (n=364). Participants were categorised in the sarcopaenic or non-sarcopaenic group based on the European Working Group on Sarcopenia in Older People criteria. Primary and secondary outcome measures (1) All-cause mortality over 10 years according to the presence of sarcopaenia and (2) impact of physical function impairment, assessed using the Short Physical Performance Battery (SPPB), and multimorbidity on 10-year mortality risk in persons with sarcopaenia. Results Sarcopaenia was identified in 103 participants (29.1%). A total of 253 deaths were recorded over 10 years: 90 among sarcopaenic participants (87.4%) and 162 among non-sarcopaenic persons (65.1%; p<0.001). Participants with sarcopaenia had a higher risk of death than those without sarcopaenia (HR=2.15; 95% CI 1.02 to 4.54). When examining the effect of sarcopaenia and physical function impairment on mortality, participants with low physical performance levels showed greater mortality. Conversely, the mortality risk was unaffected by multimorbidity. Conclusions Our findings show that physical function impairment, but not multimorbidity, is predictive of mortality in older community-dwellers with sarcopaenia. Hence, in sarcopaenic older persons, interventions against functional decline may be more effective at preventing or postponing negative health outcomes than those targeting multimorbidity.

    In juvenile idiopathic arthritis (JIA), temporomandibular joint involvement is a frequent complication leading to deficient mandibular growth. Occurring unilaterally this will give rise to mandibular and maxillary asymmetry that will affect the soft tissue and the muscles and result in complex dentofacial anomaly. In the case of severe dentofacial malformation, orthognathic surgery is the only treatment option. Vertical osseodistraction of the mandibular ramus has been suggested as a means of rectifying the mandibular growth deviation and soft-tissue problems. Whether such treatment introduces dysfunctional side effects of the temporomandibular joint and muscles has been debated and concern has been raised that treatment impairs the patient's mouth opening capacity and mandibular movement. The present study prospectively evaluated 23 patients with JIA and mandibular asymmetry caused by unilateral temporomandibular joint arthritis. The authors found a clinical effect on the asymmetry with only minor subjective complaints and limited objective changes in functional parameters.

    Intimate partner violence has negative effects on women's safety and wellbeing. When immigrant women are victimized the danger and poor health may intensify. The purpose was to determine the impact of acculturation on severity of violence, danger for murder, mental health functioning, and safety behaviors of abused immigrant women. Entry data of a 7-year prospective study of 106 abused immigrant women who were first time users of safe shelter or justice services is presented. The interview included the Severity of Violence Against Women Scale, Danger Assessment, Brief Symptom Inventory (BSI), Safety Behavior Checklist, and Acculturation for Hispanics instruments. A significant (p < 0.05) positive correlation between acculturation and safety behaviors and BSI scores was established. Higher acculturation scores were associated with significantly more practiced safety behaviors and higher levels of depression. Understanding the specific needs of abuse immigrant women associated with acculturation is imperative to develop interventions to interrupt abuse and promote safety and mental well-being.

    The latissimus dorsi (LD) flap is well-known in breast reconstruction especially in previously-irradiated patients, in order to have a low capsular contraction rate whenever an implant is associated. The aim of this study is to closely evaluate the effect of LD flap harvesting on shoulder function as well as specific movements related to the LD, both objectively and subjectively. We retrospectively collected data on 86 patients who underwent pedicled LD muscle flap for breast reconstruction at the European Institute of Oncology between September 1995 until March 2011. The majority of patients showed a joint recovery superior to 80% in all joint movements examined. Disabilities of the Arm, Shoulder and Hand questionnaire revealed minimal disability similar to normal range and furthermore it appears to decrease in all sports and in particular in those who practice with LD involvement. Focusing this data, a growing, "disability-free" percentage changes depending on whether or not the patients have practiced sport could be appreciate. Copyright © 2016 Elsevier Ltd.

    Progress in (reconstructive) surgery and radiotherapy tends to improve survival and reduce oral functional deficits. Despite the growing sophistication of cancer treatment, patients still report deterioration in tongue function. Sensory function, mobility, and force of the tongue were determined in 45 patients with a carcinoma of tongue and/or floor of mouth. Measurements were performed before surgery, shortly after surgery, shortly after radiotherapy, 6, and 12 months after surgery. Surgery had a negative impact on tongue sensory function and mobility. Post-surgery radiotherapy did not further deteriorate sensory function, mobility, or force of the tongue. Patients in the surgery-radiotherapy group (SRG) had significantly worse tongue sensory function and mobility than patients in the surgery group (SG), probably caused by more advanced tumour stage and more extensive reconstructions and related scar tissue. The tongue force in patients in both groups significantly increased in the first 6 months after surgery, but this increase disappeared in the next 6 months. The authors conclude that surgery had a significant negative influence on tongue function, especially in the group of patients treated with radiotherapy. No further deterioration of tongue function was observed after post-surgical radiotherapy within the first year after surgery. Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.

    To increase knowledge of physical and sexual intimate partner violence against women, its impact on women's health and children's behavioural functioning. Physical assault and sexual assault frequently co-occur. Women who experience both physical and sexual violence are at risk of poorer health outcomes than women who experience only physical violence. The behavioural functioning of children of women who experience partner violence may be adversely affected. Cross-sectional, using baseline data from a seven-year prospective study. Data related to severity of abuse (both physical and sexual) and the outcome measures of maternal (n = 300) mental health measures, risk of lethality, chronic pain and child (n = 300) behavioural functioning were analysed. Higher physical abuse scores were significantly correlated with higher sexual abuse scores, and higher levels of physical abuse were associated with higher maternal anxiety and higher child externalisation scores. Higher levels of sexual abuse were associated with higher maternal somatisation and post-traumatic stress disorder symptoms and higher child internalisation scores and total problems. These initial findings suggest that children have behavioural functioning and coping that is closely related to their mothers' functioning, which is based on the type of abuse experienced by the mothers. As we gain a greater understanding of these issues, we will be better able to develop effective policies and therapeutic interventions to help abused women and their children. Findings for the mental health functioning of women participating in this study add to the overwhelming evidence for the importance of screening for partner violence when women present for health care and for the need for effective assistance services for women who have or are currently experiencing partner violence. They also support emerging research that indicates the great need to provide effective services for the children of abused women. © 2014 John

    Objective Promptly treated erythema migrans (EM) has good prognosis. However, some patients report persistent symptoms. Do patients with EM have more symptoms than the general population? We describe individual symptoms and general function in EM-patients at time of diagnosis and one year after treatment. Design Prospective study with 1-year follow up after treatment. Questionnaires included a modified version of the Subjective Health Complaints Inventory, comprising three additional Lyme borreliosis (LB) related symptoms. General function was assessed using a five-point scale modified from the COOP/WONCA charts. Setting Norwegian general practice. Subjects A total of 188 patients were included in a randomized controlled trial comparing three antibiotic regimens for EM, of whom 139 had complete data for this study. Main outcome measures Individual symptoms, symptom load and general function. Results Mild symptoms were common, reported by 84.9% at baseline and by 85.6% at follow-up. At baseline, patients reported a mean of 5.4 symptoms, compared with 6.2 after one year. Severely bothersome symptoms and severely impaired general function were rare. Tiredness was the most reported symptom both at baseline and at follow-up. Palsy (other than facial) was the least reported symptom, but the only one with a significant increase. However, this was not associated to the EM. Conclusion The symptom load was comparable to that reported in the general population. We found an increase in symptom load at follow-up that did not significantly affect general function. Implication: Monitoring patients’ symptom loads prior to treatment reduce the probability of attributing follow-up symptoms to LB. Key points Erythema migrans has a good prognosis.Patients treated for erythema migrans have a slight increase in symptom load one year after treatment. This increase does not affect general function. The levels of subjective health complaints in patients treated for erythema migrans are

    Capsaicin is an ingredient of red peppers that binds to transient receptor potential vanilloid subtype 1 (TRPV1), and Koreans eat more capsaicin-rich food than do Japanese. This study aimed to compare symptom generation according to TRPV1 genotypes and the intake of spicy foods. Consecutive functional dyspepsia (FD) patients who were evaluated at Konkuk University Medical Centre (Korea) and Keio University Hospital (Japan) were included. Questionnaires on spicy food intake, patient assessment of gastrointestinal symptoms (PAGI-SYM), patient assessment of quality of life, and hospital anxiety and depression scale were provided. Blood was sampled for the detection of TRPV1 polymorphisms, and upper gastrointestinal endoscopy was performed with biopsies. Of 121 included subjects, 35 and 28 carried the TRPV1 CC and GG genotypes, respectively, with the prevalence rates not differing between Japan and Korea. The prevalence of FD subtypes did not differ with the spicy food intake, TRPV1 genotypes, or Helicobacter pylori infection. Neither TRPV1 polymorphisms nor H. pylori infections were related to scores on the PAGI-SYM questionnaires, but spicy food intake was positively correlated with the scores for stomach fullness (p = 0.001) and retching (p = 0.001). Using the linear regression analysis, stomach fullness was associated with spicy food intake (p = 0.007), whereas retching was related to younger age (p < 0.001) and female gender (p = 0.014). Upper gastrointestinal symptoms are more common in subjects with a higher consumption of spicy foods, younger age and female gender, regardless of TRPV1 genotypes and the H. pylori infection status. Capsaicin-rich foods may induce stomach fullness. © 2016 John Wiley & Sons Ltd.

    For women who have mastectomy, breast reconstruction is an option which may improve psychosocial functioning. The purpose of this study was to evaluate changes in psychosocial functioning over a long follow-up period after mastectomy, specifically examining the differences between those with mastectomy alone and those who underwent postmastectomy delayed breast reconstruction (DBR). This was a prospective longitudinal survey study of women with mastectomy in which a repeated measures design was used to compare psychosocial function scores over 3 timepoints: 1) pre-mastectomy; 2) one year post-mastectomy; and 3) long-term post-mastectomy (mean 6.3 years). In addition, psychosocial functioning was compared between the mastectomy alone group and the group who elected for DBR. 67 women who completed questionnaires at all three time points were included. The long-term follow-up time post-mastectomy was 75.2 months (6.3 years). Twenty-eight women (41.8%) underwent DBR in the study period. For the entire cohort, between one-year and long-term post-mastectomy, there were significant improvements in scores for body concerns (P = 0.03), cancer-related distress (P = 0.01), and total distress (P = 0.04). At long-term follow-up, women with DBR had significantly higher levels of total distress (P = 0.01), obsessiveness (P = 0.03), and cancer-related distress (P = 0.02) compared to those with mastectomy alone. There were no differences in quality of life between the two groups at any time point. Psychosocial functioning improves over time in patients treated with mastectomy in the long-term breast cancer survivorship period, which may be related to the effect of time post-treatment, rather than an effect of choice for or against DBR. © 2014 Wiley Periodicals, Inc.

    Background Early treatment of Alzheimer’s disease may reduce its devastating effects. By focusing research on asymptomatic individuals with Alzheimer’s disease pathology (the preclinical stage), earlier indicators of disease may be discovered. Decreasing cerebrospinal fluid beta-amyloid42 is the first indicator of preclinical disorder, but it is not known which pathology causes the first clinical effects. Our hypothesis is that neuropsychological changes within the normal range will help to predict preclinical disease and locate early pathology. Methods and Findings We recruited adults with probable Alzheimer’s disease or asymptomatic cognitively healthy adults, classified after medical and neuropsychological examination. By logistic regression, we derived a cutoff for the cerebrospinal fluid beta amyloid42/tau ratios that correctly classified 85% of those with Alzheimer’s disease. We separated the asymptomatic group into those with (n = 34; preclinical Alzheimer’s disease) and without (n = 36; controls) abnormal beta amyloid42/tau ratios; these subgroups had similar distributions of age, gender, education, medications, apolipoprotein-ε genotype, vascular risk factors, and magnetic resonance imaging features of small vessel disease. Multivariable analysis of neuropsychological data revealed that only Stroop Interference (response inhibition) independently predicted preclinical pathology (OR = 0.13, 95% CI = 0.04–0.42). Lack of longitudinal and post-mortem data, older age, and small population size are limitations of this study. Conclusions Our data suggest that clinical effects from early amyloid pathophysiology precede those from hippocampal intraneuronal neurofibrillary pathology. Altered cerebrospinal fluid beta amyloid42 with decreased executive performance before memory impairment matches the deposits of extracellular amyloid that appear in the basal isocortex first, and only later involve the hippocampus. We propose that Stroop

    To evaluate the prevalence of malnutrition and its impact on mortality, functional decline and cognitive impairment among elder residents in long-term care settings. A prospective cohort study. Two veteran homes in Taiwan. A total of 1,248 male residents aged equal or more than 65 years. Charlson's comorbidity index (CCI), Minimum data set (MDS), resident assessment protocols (RAP), Activity of daily living-Hierarchy scale, Cognitive Performance Scale, MDS Social engagement scale. The mean age of participants is 83.1 ± 5.1 years, and the prevalence of malnutrition was 6.1%. Inadequate dietary content (57.9%) and unintentional weight loss (31.6%) account for the majority of malnutrition identified by MDS tool. Higher 18-month mortality rate (25% vs. 14.2%), higher baseline CCI (median 1 vs. 0), and higher baseline sum of RAP triggers (median 8.5 vs. 5) were noted among residents with malnutrition. Furthermore, malnutrition was shown predictive for functional decline (OR: 3.096, 95% CI: 1.715-5.587) and potential cognitive improvement (OR: 2.469, 95% CI: 1.188-5.128) among survivors after adjustment for age, body mass index and CCI. Malnutrition among elder men residing in veteran homes was associated with multimorbidities and higher care complexity, and was predictive for mortality and functional decline.

    To compare the effects of a bolus dose of milrinone, 50 microg/kg, to placebo on diastolic function (active relaxation) in patients undergoing on-pump coronary artery bypass grafting (CABG). Prospective, randomized, double-blind, placebo-controlled study. University hospital. Twenty-four patients with stable angina and left ventricular ejection fraction >30%, scheduled for elective CABG using cardiopulmonary bypass (CPB), were included. Patients were randomized to receive either 50 microg/kg of milrinone (n = 12) or placebo (n = 12) after aortic declamping. The diastolic function of the left ventricle (LV) was measured as peak filling rate (dA/dt [maximal diastolic area change over time]) with transesophageal echocardiography (TEE) using acoustic quantification (AQ) before CPB and 10 minutes after termination of CPB. The normalized peak filling rate (dA/dt)/EDA was also calculated. Active relaxation was statistically significantly increased in the milrinone group compared with the placebo group after CPB. Patients undergoing CABG surgery and treated with milrinone after aortic declamping had better diastolic function following cardiopulmonary bypass. Copyright (c) 2010 Elsevier Inc.

    We investigated whether patients with lengthening (> 9 mm), restoration (between 9 mm lengthening and 5 mm shortening) or shortening (> 5 mm) of the operated leg after total hip arthroplasty (THA) had different function (WOMAC score), quality of life (EQ-5D), residual hip pain, use of shoe lift and walking aid and leg length discrepancy (LLD) awareness, 12-15 months postoperatively. All patients had a significant postoperative improvement in WOMAC and EQ-5D regardless the LLD. However, the lengthening group showed less improvement in WOMAC, more use of shoe lift, residual hip pain and LLD awareness compared with the other two groups. No differences in EQ-5D were found. In spite of the improvement in function and quality of life, lengthening had adverse effects and should therefore be avoided. Copyright © 2015 Elsevier Inc. All rights reserved.

    The aim of the present study was to determine if the use of the anti-tumor necrosis factor (TNF)-α monoclonal antibody adalimumab could improve endothelial function and arterial stiffness in patients with moderate to severe psoriasis. This was a prospective study on a series of consecutive patients with moderate to severe psoriasis who completed 6 months of therapy with adalimumab. Patients with history of cardiovascular events, diabetes mellitus, kidney disease, hypertension or body mass index of 35 kg/m(2) or more were excluded. Assessment of endothelial function by brachial artery reactivity measuring flow-mediated endothelial dependent vasodilatation (FMD%), and carotid arterial stiffness by pulse wave velocity (PWV) was performed at the onset of treatment (time 0) and at month 6. Twenty-nine patients were studied. Anti-TNF-α adalimumab therapy yielded a significant improvement of endothelial function. The mean ± standard deviation (SD) FMD% values increased from 6.19 ± 2.44% at the onset of adalimumab to 7.46 ± 2.43% after 6 months of treatment with this biologic agent (P = 0.008). Likewise, following the use of adalimumab, PWV levels decreased from 6.28 ± 1.04 m/s at the onset of adalimumab to 5.69 ± 1.31 m/s at 6 months (P = 0.03). In conclusion, patients with moderate to severe psoriasis exhibit improvement of endothelial function and arterial stiffness following anti-TNF-α therapy. These findings are of potential relevance due to increased risk of cardiovascular disease in patients with severe psoriasis.

    Facial nerve paresis and hearing loss are common complications after vestibular schwannoma surgery. Experiments with facial nerves of the rat and retrospectively analyzed clinical studies showed a beneficial effect of vasoactive treatment on the preservation of facial and cochlear nerve functions. This prospective and open-label randomized pilot study is the first study of a prophylactic vasoactive treatment in vestibular schwannoma surgery. Thirty patients were randomized before surgery. One group (n = 14) received a vasoactive prophylaxis consisting of nimodipine and hydroxyethylstarch which was started the day before surgery and was continued until the seventh postoperative day. The other group (n = 16) did not receive preoperative medication. Intraoperative monitoring, including acoustic evoked potentials and continuous facial electromyelograms, was applied to all patients. However, when electrophysiological signs of a deterioration of facial or cochlear nerve function were detected in the group of patients without medication, vasoactive treatment was started immediately. Cochlear and facial nerve function were documented preoperatively, during the first 7 days postoperatively, and again after long-term observation. Despite the limited number of patients, our results were significant using the Fisher's exact test (small no. of patients) for a better outcome after vestibular schwannoma surgery for both hearing (P = 0.041) and facial nerve (P = 0.045) preservation in the group of patients who received a prophylactic vasoactive treatment. Prophylactic vasoactive treatment consisting of nimodipine and hydroxyethylstarch shows significantly better results concerning preservation of the facial and cochlear nerve function in vestibular schwannoma surgery. The prophylactic use is also superior to intraoperative vasoactive treatment.

    The long-stem Exeter femoral component is commonly used in revision hip surgery. Subsidence of the femoral stem in primary hip arthroplasty has been studied extensively, but much less is known about its significance in revision surgery. This prospective study examined the relationship between radiological subsidence, Western Ontario and McMaster (WOMAC) osteoarthritis index pain score, patient satisfaction and complication rates for the long-stem Exeter hip prosthesis. Data was prospectively collected for a single-surgeon series of 96 patients undergoing revision surgery with a mean follow-up period of 36 months. Pre- and post-operative clinical evaluation was carried out using the validated WOMAC osteoarthritis index. Radiographic evaluation was carried out on magnification-adjusted digital radiographic images. Data from 57 patients were analysed. The mean rate of subsidence recorded was 0.43 mm/year, with a mean total subsidence of 0.79 mm [95% confidence interval (CI) 0.57-1.01] at 36.3 months. There was no correlation between subsidence and post-operative WOMAC score, complication rate or patient satisfaction. There was a statistically significant reduction between pre-operative and post-operative WOMAC scores, with means of 33.5 and 10.7, respectively (P < 0.001), and high patient satisfaction. Our subsidence rates for long-stem revision femoral components are lower than the published data but demonstrate the same plateau. Radiographic subsidence does not appear to relate to functional outcome or complication rates in our data.

    Penile cancer is a rare malignancy worldwide, representing only 1% of all cancers affecting men. There are little data outlining the comparative effectiveness of penile preservation techniques and to our knowledge no guidelines regarding their use currently exist. Outcomes data reporting is nonstandardized and followup is not measured consistently. The aim of this study was to analyze the outcomes of total glans resurfacing in terms of oncologic control, form and function in localized penile cancer. From 2013 to 2015, 19 prospectively enrolled patients underwent total glans resurfacing. Demographics, cosmesis, patient satisfaction and disease recurrence were assessed at followup to quantify oncologic and functional outcomes. At 3 months of followup patients completed the IIEF (International Index of Erectile Function) questionnaire detailing erectile and sexual function, and general satisfaction using a visual analog scale. All statistical analysis was performed with Prism® 6. No perioperative complications were experienced. Of the patients 94.7% had complete graft take with a median cosmesis score of 5 of 5 on the visual analog scale. There was 1 local and no regional nodal recurrence at a mean followup of 23 months. One-year progression-free and overall survival rates were 100% and the 1-year recurrence-free survival rate was 95%. Of the patients 81% reported an improved sex life postoperatively. Total glans resurfacing is a viable and acceptable option for glans preservation in patients with localized penile cancer. It demonstrates acceptable functional and oncologic outcomes. We believe that total glans resurfacing should be considered in all cases of localized penile cancer. Copyright © 2017 American Urological Association Education and Research, Inc.

    Background and Aims: Antihypertensive drugs are continued until the day of renal transplant surgery. These are associated with increased incidence of hypotension and bradycardia. Hence, this study was designed to evaluate perioperative haemodynamic and early graft functioning in renal recipients with discontinuation of antihypertensive drugs on the morning of surgery. Methods: This prospective, randomised, double-blind study recruited 120 patients. Group 1 patients received placebo tablet while Group 2 patients received usual antihypertensive drugs on the day of surgery. Perioperative haemodynamics and time for reinstitution of antihypertensives were the primary outcome measures. The secondary outcome measures were need for inotropic support and graft function. Perioperative haemodynamics were analysed using ANOVA and Student's t-tests with Bonferroni correction. Fischer's exact test was used for analysis. Results: Systolic blood pressure (SBP) declined, which was more in Group 2. Forty-one patients developed significant hypotension; a correlation was found between the maximum observed hypotension and number of antihypertensive medications (P = 0.003). Four cases had slow graft function (one in Group 1 and three in Group 2). Twenty-eight patients in Group 2 required mephentermine boluses to maintain their SBP compared to 13 patients in Group 1 (P < 0.001). Two patients in Group 2 required dopamine to maintain SBP above 90 mmHg after the establishment of reperfusion as compared to none in Group 1. Conclusion: Single dose of long-acting antihypertensive drugs can be omitted on the morning of surgery without any haemodynamic fluctuations and graft function in controlled hypertensive end-stage renal disease renal transplant patients receiving a combined epidural and general anaesthesia.

    Background Three‐dimensional transthoracic echocardiography (3D‐TTE) with dedicated software permits quantification of mitral annulus dynamics and papillary muscle motion throughout the cardiac cycle. Methods and Results Mitral apparatus 3D‐TTE was acquired in controls (n=42), patients with left ventricle dysfunction and functional mitral regurgitation (LVD‐FMR; n=43) or without FMR (LVD‐noMR, n=35). Annulus in both normal and LVD‐noMR subjects displayed saddle shape accentuation in early‐systole (ratio of height to intercommissural diameter, 10.6±3.7 to 13.5±4.0 in normal and 9.1±4.3 to 12.6±3.6 in LVD‐noMR; P<0.001 for diastole to early‐systole motion, P=NS between those groups). In contrast, saddle shape was unchanged from diastole in FMR patients (10.0±6.4 to 8.0±5.2; P=NS, P<0.05 compared to both other groups). Papillary tips moved symmetrically towards to the midanterior annulus in control and LVD‐noMR subjects, maintaining constant ratio of the distances between both tips to midannulus (PtAR) throughout systole. In LVD‐FMR patients midsystolic posterior papillary tip to anterior annulus distance was increased, resulting in higher PtAR (P=0.05 compared to both other groups). Mechanisms of early‐ and midsystolic FMR differed between different etiologies of LV dysfunction. In patients with anterior MI and global dysfunction annular function and dilatation were the dominant parameters, while papillary muscle motion was the predominant determinant of FMR in patients with inferior MI. Conclusions Inadequate early‐systolic annular contraction and saddle‐shape accentuation in patients with impaired LV contribute to early–mitral incompetency. Asymmetric papillary tip movement towards the midanterior annulus is a major determinant of mid‐ and late‐systolic functional mitral regurgitation. PMID:23727698

    To investigate coping flexibility in patients with newly acquired brain injury and to investigate the influence of problem type, self-efficacy, self-awareness and self-reported executive functions on coping flexibility. Data were collected from a prospective clinical cohort study of 136 patients assessed after discharge home (mean time since injury = 15 weeks) and 1 year later. Situation-specific coping was measured by asking patients to complete the Coping Inventory for Stressful Situations (CISS) for 3 acquired brain injury (ABI)-related situations, which were then categorized into problem types (physical, cognitive, emotional, behavioural, communication, other). Coping consistency (number of strategies used throughout every situation) and variability (range in frequency of use of strategies over situations) were measured. Random effects regression analyses were used. Patients used more task-oriented coping for cognitive compared with physical problems. Coping variability was limited. Reliance on emotion-oriented coping decreased over time. Higher self-efficacy correlated with increased task-oriented and avoidance coping and decreased emotion-oriented coping. Greater self-reported problems in executive function correlated with greater consistency in task-oriented and emotion-oriented strategies. Patients with acquired brain injury rely on a defined set of coping options across situations and time. High self-efficacy increases active coping. Subjective executive dysfunction might hamper effective strategy selection.

    This was to clarify dentoalveolar, skeletal and facial profile modifications induced by Fränkel II functional treatment in Class II division 1 subjects in prepubertal stages CS1-2. Evaluation of 25 caucasian subjects (15 males, 10 females), mean age 8y 11m, in vertebral stages CS1-2. The mean duration of functional treatment was 1y 11m. Prospective controlled study. The sample was evaluated at T0, start of treatment, and T1, end of Fränkel II therapy. Untreated subjects in Class II division 1 were the control group. T-test for paired data was calculated before and after treatment (P< 0.05). A statistically significant increase between T0 and T1 was obtained for SNB (p = 0.022), ANB (p <0.001), Mx/Mn differential (p = 0.001), Co-Go-Me (p = 0.014), OJ (p < 0.001), OB (p = 0.042), IMPA (p = 0.021) . OJ (p < 0.001) and OB (p = 0.003) showed a higher significant change in the Fränkel group compared to control group. The Fränkel II appliance produced, in CS1-2 subiects, significant effects in teeth position, skeletal modifications and soft tissue changes, although the pubertal growth spurt would occur at least two years later.

    The purpose of this study is to know the incidence rate of medication reconciliation at admission and discharge in patients of La Rioja and to improve the patient safety on medication reconciliation. An observational prospective study, part of the Joint Action PaSQ, Work Package 5, European Union Network for Patient Safety and Quality of Care. The study has taken into account the definitions of the Institute for Safe Medication Practices. Any unintended discrepancy in medication between chronic treatment and the treatment prescribed in the hospital was considered as a reconciliation error. A total of 750 patients were included, 9 (1.2%) of whom showed at least one discrepancy. The patients had a total of 3,156 mediations registered: 2,313 prescriptions (73.4%) showed no differences, while 821 prescriptions (26%) were intended discrepancies and 21 prescriptions (0.6%) unintended discrepancies were considered by the physician as reconciliation errors. A percentage of 1.2 of the patients, which represents 0.6% of the medicines (one in 166 medications registered) had reconciliation errors during their hospital stay. A proceeding has been implemented by means of the physician doing the medication reconciliation and reviewing it with the help of a medication reconciliation form. The medication reconciliation is a priority strategic objective to improve the safety of patients. Copyright © 2016 SECA. Published by Elsevier Espana. All rights reserved.

    The Instituto Nacional de Rehabilitación (Rehabilitation National Institute) (INR) developed a prototype wheelchair cushion (INR cushion) designed to adjust to the anthropometry of the user's ischiogluteal area and prevent pressure ulcer formation while maintaining or promoting functionality. A prospective, longitudinal, descriptive study was conducted from February 2010 to February 2011 to evaluate the effect of using the INR cushion on clinical variables, functionality, and user satisfaction. Sixteen patients were recruited (9 male, 7 female, average age 31.8 [range 22-47] years, average body mass index 25 [range 22-34], average time in a wheelchair 10.1 [range 3-26] years) who met the study protocol inclusion criteria of being pressure ulcer-free for at least 6 months and capable of propulsion and transfer without assistance, chronic spinal cord injury (>2 years), and without chronic-degenerative diseases or cognitive problems. Each participant received the cushion for a 2-month evaluation. Eight clinical variables were assessed: trunk control, posture, spasticity, transfer capacity, comfort, skin reaction, propulsion capacity, and pressure release capacity. The clinical assessment was performed using validated scales and instruments: Modified Ashworth Scale (MAS), Functional Independence Measure™ (FIM), Norton Scale, and assessment of skin reaction. Interface pressures were measured using force sensing array, and participants completed a structured interview to assess user expectation, perceived functionality, perceived quality, and likelihood of recommending the device. Two patients withdrew due to appointment conflicts; of the remaining 14, significant differences between the user's experience with other products and the INR were found with regard to pressure redistribution (P = 0.012); all participants but 1 graded the INR as good in all interview categories. No participants developed a pressure ulcer during the study. The customized cushion was

    One of the currently used surgical techniques in isolated type II SLAP lesions is arthroscopic SLAP repair. Postoperatively, patients tend to suffer from a prolonged period of pain and are restricted in their sports activities for at least 6 months. The aim of this study was to prospectively evaluate the clinical outcome as well as the postoperative course of pain after arthroscopic type II SLAP repair. Outcome measures were assessed using the Individual Relative Constant Score (CSindiv), the American Shoulder and Elbow Surgeons (ASES) Score, the Visual Analogue Scale (VAS), and the Short Form 36 (SF-36). Data were collected preoperatively, as well as at 3, 6, 12 and >24 months postoperatively. Eleven patients with an average age of 31.8 years (range: 22.8-49.8 years) underwent arthroscopic repair of isolated type II SLAP lesions. Mean follow-up time was 41.9 months (range: 36.1-48.4 months). 6 months after surgery, there was a statistically significant improvement of function according to the CSindiv (p = 0.004), the ASES Score (p = 0.006), and the SF-36 subscale "physical functioning" (p = 0.014) and a statistically significant decrease of pain according to the VAS (p = 0.007) and the SF-36 subscale "bodily pain" (p = 0.022) compared to preoperative levels. Arthroscopic repair of isolated type II SLAP lesions with suture anchors leads to a satisfactory functional outcome and return to pre-injury sports levels, with delayed, but significant pain relief observed 6 months after surgery. Thus, a return to sports should not be allowed earlier than 6 months after surgery, when patients have reached pain-free function and recovered strength. Researchregistry1761 (UIN).

    Decreased frequency of going outside the home and being socially isolated are regarded as predictors of poor health. The object of the present study was to clarify whether these factors have synergistic or independent impacts on future functional decline. We examined a prospective cohort of 2427 community-dwelling persons, aged ≥65 years, who responded to the baseline mail survey in Wako City, in 2008. Participants were asked about the frequency of going outside the home, social isolation status (having contact less than once a week with anyone outside household), functional capacity (Tokyo Metropolitan Institute of Gerontology-Index of Competence), age, sex, annual income, self-rated health, depressive mood and mobility. Of 1575 persons (72.1%) who completely responded to the follow-up survey (T2) in 2012, we defined the groups as follows: group 1, not isolated and going outside the home every day (n = 897); group 2, not isolated and going outside the home less than every day (n = 311); group 3, isolated and going outside the home every day (n = 224); and group 4, isolated and going outside the home less than every day (n = 143). Multiple logistic regression analyses showed that the variables identifying group 3 for men and group 2 for women with reference to group 1 were predictors of subsequent functional decline even after adjustment for confounders (odds ratios 2.01, 1.63; 95% CI 1.20-3.38, 1.03-2.56, respectively). Social isolation regardless of going outside the home every day for men and going outside the home less than every day regardless of being not socially isolated for women might predict functional decline.

    Introduction: Perioperative anesthesia and analgesia exacerbate immunosuppression in immunocompromised cancer patients. The natural killer (NK) cell is a critical part of anti-tumor immunity. We compared the effects of two different anesthesia and analgesia methods on the NK cell cytotoxicity (NKCC) in patients undergoing breast cancer surgery. Methods: Fifty patients undergoing breast cancer resection were randomly assigned to receive propofol-remifentanil anesthesia with postoperative ketorolac analgesia (Propofol-ketorolac groups) or sevoflurane-remifentanil anesthesia with postoperative fentanyl analgesia (Sevoflurane-fentanyl group). The primary outcome was NKCC, which was measured before and 24 h after surgery. Post-surgical pain scores and inflammatory responses measured by white blood cell, neutrophil, and lymphocyte counts were assessed. Cancer recurrence or metastasis was evaluated with ultrasound and whole body bone scan every 6 months for 2 years after surgery. Results: The baseline NKCC (%) was comparable between the two groups (P = 0.082). Compared with the baseline value, NKCC (%) increased in the Propofol-ketorolac group [15.2 (3.2) to 20.1 (3.5), P = 0.048], whereas it decreased in the Sevoflurane-fentanyl group [19.5 (2.8) to 16.4 (1.9), P = 0.032]. The change of NKCC over time was significantly different between the groups (P = 0.048). Pain scores during 48 h after surgery and post-surgical inflammatory responses were comparable between the groups. One patient in the Sevoflurane-fentanyl group had recurrence in the contralateral breast and no metastasis was found in either group. Conclusions: Propofol anesthesia with postoperative ketorolac analgesia demonstrated a favorable impact on immune function by preserving NKCC compared with sevoflurane anesthesia and postoperative fentanyl analgesia in patients undergoing breast cancer surgery.

    Introduction Long-term outcomes of elderly patients after medical ICU care are little known. The aim of the study was to evaluate functional status and quality of life of elderly patients 12 months after discharge from a medical ICU. Methods We prospectively studied 112/230 healthy elderly patients (≥65 years surviving at least 12 months after ICU discharge) with full functional autonomy without cognitive impairment prior to ICU entry. The main diagnoses at admission using the Acute Physiology and Chronic Health Evaluation III (APACHE III) classification diagnosis and length of ICU stay and ICU scores (APACHE II, Sepsis-related Organ Failure Assessment (SOFA) and OMEGA) at admission and discharge were collected. Comprehensive geriatric assessment included the presence of the main geriatric syndromes and the application of Lawton, Barthel, and Charlson Indexes and Informant Questionnaire on Cognitive Decline to evaluate functionality, comorbidity and cognitive status, respectively. The EuroQol-5D assessed quality of life. Data were collected at baseline, during ICU and ward stay and 3, 6 and 12 months after hospital discharge. Paired or unpaired T-tests compared differences between groups (continuous variables), whereas the chi-square and Fisher exact tests were used for comparing dichotomous variables. For variables significant (P ≤ 0.1) on univariate analysis, a forward multiple regression analysis was performed. Results Only 48.9% of patients (mean age: 73.4 ± 5.5 years) were alive 12 months after discharge showing a significant decrease in functional autonomy (Lawton and Barthel Indexes) and quality of life (EuroQol-5D) compared to baseline status (P < 0.001, all). Multivariate analysis showed a higher Barthel Index and EQ-5D vas at hospital discharge to be associated factors of full functional recovery (P < 0.01, both). Thus, in patients with a Barthel Index ≥ 60 or EQ-5D vas ≥40 at discharge the hazard ratio for full functional recovery was 4.04 (95

    This study compared the clinical and physiological results of non-sphincter splitting fistulectomy (N-SSF) with those of sphincter splitting fistulotomy (SSF) for treatment of high trans-sphincteric fistula-in-ano. A prospective, observational study was undertaken in 70 consecutive patients with high trans-sphincteric fistula treated by SSF (n = 35) or N-SSF (n = 35). Anal manometry was performed before and 3 months after surgery. Anal continence was assessed using the Cleveland Clinic Florida Incontinence Score. There was no difference between the two groups in age, gender, presence of horseshoe extension, preoperative incontinence score and manometric values. The incidence of recurrence was similar between the two groups. The postoperative incontinence score of the SSF group was significantly higher than that of the N-SSF group (1.9 +/- 2.9 vs 1.1 +/- 2.9, P = 0.0347). Maximum resting pressure showed significant decrease after surgery in both groups (83.2 to 56.1 mmHg, P = 0.0001 and 85.1 to 58.4 mmHg, P = 0.0001). Voluntary contraction pressure and functional anal canal length did not change after N-SSF (137.6 to 138.2 mmHg, P = 0.9524 and 4.06 to 4.07 cm, P = 0.9524), but significantly decreased after SSF (120.2 to 96.7 mmHg, P = 0.0085 and 4.12 to 3.74 cm, P = 0.0183). Non-sphincter splitting fistulectomy for high trans-sphincteric fistula provided better functional results than fistulotomy. Less impairment of anal continence was achieved possibly not only by maintenance of the external anal sphincter function but also by preservation of the length of the high-pressure zone.

    The purpose of this two-part study was to demonstrate the impact of free flap breast reconstruction on the abdominal wall. In Part I, the authors present the results for unilateral techniques. A blinded, prospective, cohort study was performed involving 234 free flap breast reconstruction patients. Patients were evaluated preoperatively, and followed for 1 year. At each encounter, patients underwent abdominal strength testing using the Upper and Lower Rectus Abdominis Manual Muscle Function Test, the Functional Independence Measure, and psychometric testing using the 36-Item Short-Form Health Survey. Patients also completed a satisfaction questionnaire specific to breast reconstruction. Statistical analysis included the Kruskal-Wallis, Mann-Whitney, Friedman, and Wilcoxon signed rank tests. Two-hundred thirty-four patients were enrolled. Of these, 157 underwent reconstruction (75 of which were unilateral), completed follow-up, and were included in the analysis. There was a significantly greater decline in upper abdominal strength in patients undergoing muscle-sparing free transverse rectus abdominis musculocutaneous (TRAM) flap surgery compared with deep inferior epigastric perforator (DIEP) flap surgery at early (p = 0.01) and late follow-up (p = 0.02). Unilateral superficial inferior epigastric artery flap procedures (n = 3) were too few for a meaningful conclusion to be reached. Lower abdominal and Functional Independence Measure scores showed no significant differences. Psychometric testing showed that there was a significant decline in physical health within the free TRAM flap group. No significant difference among groups was appreciable. In unilateral cases, the impact of the muscle-sparing free TRAM flap versus the DIEP flap follows theoretical predictions based on the degree of muscle sacrifice: the muscle-sparing free TRAM flap demonstrated a greater decline than the DIEP flap in certain measurable parameters.

To evaluate the effects of intravaginal contraception on weight gain and perceived body image in relation with the Beck's Depression Inventory questionnaire (BDI) and the McCoy Female Sexuality Questionnaire (MFSQ). Twenty-one adult (18-35 years old) eumenorrheic (menstrual cycle of 25-35 days), lean (body mass index - BMI - of 19-25 kg/m(2)) women who were referred for hormonal contraception were administered the Stunkard Figure Rating Scale (FRS), BDI and MFSQ. Subjects were studied in basal condition and after 6 months of therapy with vaginal contraception (NuvaRing®; Organon-Schering-Plough Italia, Milan, Italy). BMI, FRS, MFSQ and BDI. After 6 months of therapy with NuvaRing®, both body weight (60.0 ± 8.3; p = 0.050) and BMI (22.1 ± 3.1; p = 0.028) slightly, but statistically, increased. FRS and BDI showed no differences after the vaginal contraception. Hormonal contraception was associated with a significant decrease in the two-factor Italian MFSQ score. Vaginal ring seems a good alternative to other hormonal contraceptive not significantly altering the female sexuality and not influencing the FRS and BDI.

  15. Prospect evaluation as a function of numeracy and probability denominator.

    PubMed

    2015-05-01

    This study examines how numeracy and probability denominator (a direct-ratio probability, a relative frequency with denominator 100, a relative frequency with denominator 10,000) affect the evaluation of prospects in an expected-value based pricing task. We expected that numeracy would affect the results due to differences in the linearity of number perception and the susceptibility to denominator neglect with different probability formats. An analysis with functional measurement verified that participants integrated value and probability into an expected value. However, a significant interaction between numeracy and probability format and subsequent analyses of the parameters of cumulative prospect theory showed that the manipulation of probability denominator changed participants' psychophysical response to probability and value. Standard methods in decision research may thus confound people's genuine risk attitude with their numerical capacities and the probability format used.

  16. Static balance and function in children with cerebral palsy submitted to neuromuscular block and neuromuscular electrical stimulation: Study protocol for prospective, randomized, controlled trial

    PubMed Central

    2012-01-01

    Background The use of botulinum toxin A (BT-A) for the treatment of lower limb spasticity is common in children with cerebral palsy (CP). Following the administration of BT-A, physical therapy plays a fundamental role in potentiating the functionality of the child. The balance deficit found in children with CP is mainly caused by muscle imbalance (spastic agonist and weak antagonist). Neuromuscular electrical stimulation (NMES) is a promising therapeutic modality for muscle strengthening in this population. The aim of the present study is to describe a protocol for a study aimed at analyzing the effects of NMES on dorsiflexors combined with physical therapy on static and functional balance in children with CP submitted to BT- A. Methods/Design Protocol for a prospective, randomized, controlled trial with a blinded evaluator. Eligible participants will be children with cerebral palsy (Levels I, II and III of the Gross Motor Function Classification System) between five and 12 years of age, with independent gait with or without a gait-assistance device. All participants will receive BT-A in the lower limbs (triceps surae). The children will then be randomly allocated for either treatment with motor physical therapy combined with NMES on the tibialis anterior or motor physical therapy alone. The participants will be evaluated on three occasions: 1) one week prior to the administration of BT-A; 2) one week after the administration of BT-A; and 3) four months after the administration of BT-A (end of intervention). Spasticity will be assessed by the Modified Ashworth Scale and Modified Tardieu Scale. Static balance will be assessed using the Medicapteurs Fusyo pressure platform and functional balance will be assessed using the Berg Balance Scale.

    Prospective study. To assess the timing and predictors of return to short-term functional activity in patients with adolescent idiopathic scoliosis (AIS) after posterior spinal fusion (PSF). Few studies have examined the timing and rate of return to short-term functional activity in patients with AIS after PSF. No study has yet evaluated the timing and factors that predict a delayed return to school/college--a topic relevant to patients who have had or anticipate having spinal fusion, and their treating surgeons. Seventy-seven eligible subjects with AIS who underwent PSF and correction (January 2010 to April 2012) were followed up until return to the functional outcomes under analysis. Timing of return to school/college and physical activity, as per the patients' preoperative level or better, was assessed. Binary logistic regression analysis was used to determine predictors of delayed return to school/college full-time (>16 wk) and unrestricted physical activity (>32 wk) relative to sociodemographic, anthropometric, radiographical, clinical, and surgical factors. In the present study, a "delayed" return to all the functional outcomes recorded was defined as "greater than the 75th percentile" of the continuous distribution. Mean follow-up was 12.8 months (SD, 5.7). Mean age was 15.04 years (SD, 1.89). The median time to return to school/college full-time (n = 75) was 10 weeks; the majority returned by 16 weeks (77.3%). Preoperative curves greater than 70° (relative risk, 3.38; P = 0.008), postoperative weight loss greater than 5 kg (relative risk, 3.02; P = 0.012), and minor perioperative respiratory complication incidence (relative risk, 2.89; P = 0.024) independently predicted delayed return to school/college full-time. By 24 and 52 weeks, 51.4% and 88.5% of subjects, respectively, returned to unrestricted physical activity. At final follow-up, nonreturn to unrestricted physical activity was identified in only 3 subjects (4.3%) because of chronic back pain. The

    Background The impact of postoperative delirium on post-discharge functional status of older patients remains unclear, and little is known regarding the interrelationship between cognitive impairment and post-operative delirium. Therefore, the main purpose was to evaluate the post-discharge functional status of patients who experience delirium after undergoing orthopaedic surgery and the interrelationship of postoperative delirium with underlying cognitive impairment. Method This prospective cohort study, conducted at a tertiary care medical center from April 2011 to March 2012, enrolled all subjects aged over 60 years who were admitted for orthopaedic surgery. The baseline characteristics (age, gender, BMI, and living arrangement), surgery-related factors (ASA class, admission type, type of surgery, and length of hospital stay), results of geriatric assessment (postoperative delirium, cognition, depressive mood, comorbidity, pain, malnutrition, polypharmacy, ADL, and instrumental [I]ADL) and 1–12-month postoperative ADL and IADL functional status were collected for analysis. Results Overall, 9.1% of 232 patients (mean age: 74.7±7.8 years) experienced postoperative delirium, which was significantly associated with IADL decline at only 6 and 12 months postoperatively (RR: 6.22, 95% CI: 1.08–35.70 and RR: 12.54, 95% CI: 1.88–83.71, respectively). Delirium superimposed on cognitive impairment was a significant predictor for poor functional status at 6 and 12 months postoperatively (RR: 12.80, 95% CI: 1.65–99.40 for ADL at the 6th month, and RR: 7.96, 95% CI: 1.35–46.99 at the 12th month; RR: 13.68, 95% CI: 1.94–96.55 for IADL at the 6th month, and RR: 30.61, 95% CI: 2.94–318.54 at the 12th month, respectively). Conclusion Postoperative delirium is predictive of IADL decline in older patients undergoing orthopaedic surgery, and delirium superimposed on cognitive impairment is an independent risk factor for deterioration of ADL and IADL functional status

    Head and neck cancer (HNC) is a debilitating disease due in part to its effects on function, including speech, swallowing, and cosmesis. Previous studies regarding depression in HNC have focused on demographic predictors, incidence, and quality of life studies. There is, however, a paucity of studies that objectively address depressive symptoms in HNC patients and the resultant effects on post-treatment functional performance status. The aim of this study was to assess the relationship between preoperative depressive symptoms (PDS) and postoperative functional performance status (PFPS), in addition to other predictors of rehabilitation and survival. A prospective cohort study was undertaken at the University of Alberta, including all new adult HNC patients undergoing surgery as primary therapy for HNC from May 2013 to January 2014. Baseline depressive symptoms were measured on the Quick Inventory of Depressive Symptoms (QIDS) questionnaire 2 weeks preoperatively and PFPS was assessed 12 months postoperatively on the Functional Assessment of Cancer Therapy-Head & Neck (FACT-HN) scale. Secondary outcomes included completion of adjuvant therapy, narcotic dependence, return to detrimental habits, loss of follow-up, and length of hospital stay (LOHS). Differences between the Normal-Mild and Moderate-Severe QIDS groups were assessed using Mann-Whitney and Fischer Exact statistical analyses. Seventy-one patients were included in the study. Mild and Moderate-Severe PDS were 35.2 % and 18.3 %, respectively. Significantly lower FACT-HN scores were noted in the Moderate-Severe group at 12 months (p = 0.03). The risk ratio (RR) for FACT-HN score < 50 % at 12 months in the Moderate-Severe group was 5.66. In addition, significantly lower completion of adjuvant treatment (p = 0.03), significantly higher incidence of narcotic dependence (p = 0.004), and significantly higher LOHS (24 days vs. 18 days; p = 0.02) was observed in the Moderate-Severe group

    The aim of this study was to prospectively evaluate the cognitive function, depression, anxiety, and sleep quality in patients with nasopharyngeal cancer (NPC) before and after intensity-modulated radiotherapy (IMRT). Eligible patients with newly diagnosed NPC treated with primary IMRT were recruited. A series of neuropsychological tests were performed within 1 week before and after IMRT. Cognitive function was measured with the Das-Naglieri cognitive assessment system. The Self-rating Anxiety Scale and Self-rating Depression Scale were used to assess mood states. Sleep quality was evaluated by means of the Pittsburgh Sleep Quality Index. A total of 51 patients were enrolled. The overall prevalence of depression, anxiety, and poor sleep quality showed a significant increase after RT, compared with their pre-RT levels (39.2% vs. 3.9%, p = 0.000; 19.6% vs. 3.9%, p = 0.039; 64.7% vs. 37.3%, p = 0.003, respectively). Multiple linear regression analysis revealed that pre-RT depression and younger age and pre-RT anxiety and younger age were significant predictors of post-RT depression and anxiety, respectively (p < 0.05). Poor sleep quality before treatment was also associated with poor sleep after RT (p = 0.032). However, the cognitive function evaluated by the cognitive assessment system from pre-RT was similar to the post-RT results. Exposure to ionizing radiation for the treatment of NPC decreased mood and sleep quality following IMRT, especially for patients with depression, anxiety, younger age, or poor sleep before treatment. No acute cognitive deficits were found resulting from IMRT, but the long-term effects of RT might still warrant concern. Copyright © 2014 John Wiley & Sons, Ltd.

    Taurine's role in bile acid metabolism and anti-inflammatory activity could exert a protective effect on hepatobiliary complications associated with parenteral nutrition (PN). In this study, the effects of 2 amino acid solutions, with and without taurine, on liver function administered to nonacutely ill postsurgical patients as part of a short-term PN regimen were prospectively compared. Adult patients randomly received (double-blind) Tauramin 10% or a standard PN solution without taurine as the control (1.5 g amino acid/kg body weight [bw]/d; infusion rate of ≤4 mg glucose/kg bw/d) for a period of 5-30 days. γ-Glutamyl transpeptidase (GGT) and other indicators of liver function, glucose metabolism, lipid profile, inflammation markers, and treatment safety data were collected. Thirty-five patients receiving taurine PN and 39 receiving control PN were enrolled (intention-to-treat [ITT] population). Most patients (n = 62) discontinued after day 7 of follow-up (per-protocol [PP] population: n = 24 and n = 27, respectively). ITT patients with high GGT values after 5 days of PN comprised 68.6% and 64.1%, respectively. The mean change in GGT values with respect to the baseline values was 167 ± 192 and 157 ± 185 IU/L, respectively. Low-density lipoprotein (LDL) cholesterol levels after 7 days of PN were significantly decreased in the taurine PN group of PP patients (-2.83 ± 30.9 vs 23.9 ± 27.0 mg/dL for control PN; P < .05). None of the adverse events reported (taurine PN: n = 6; control PN: n = 7) were treatment related. PN solutions with and without taurine had similar effects on liver function parameters, except for an LDL reduction in PN with taurine, when administered to nonacutely ill postsurgical patients in the short term (5-7 days). © 2014 American Society for Parenteral and Enteral Nutrition.

    Alterations of thyroid functioning are common in old age. Even among persons free from thyroid disorders, subclinical variations in thyroid functioning may affect cognitive performance. However, it is unknown whether prospective memory (ProM) is related to thyroid stimulating hormone (TSH) variations. An association could be expected, as changes in the thyroid gland have been linked to alterations in frontal brain regions that play a key role in prospective remembering. Thus, the aim of this study was to examine whether subclinical variations in thyroid functioning affect ProM performance. We studied 103 participants, 75 years and older, who were free from thyroid disorders and had serum levels of TSH and thyroxine (T4) within normal ranges. Interestingly, we found a non-linear association between TSH and ProM performance, where persons with TSH levels above the fourth quartile performed substantially better than persons in the other quartiles. T4 levels were unrelated to ProM performance. This pattern suggests that the previously identified "normal-range" interval for TSH should be moved further up in old age, at least when cognitive functioning is considered.

    Recent findings suggest that executive function (EF) plays a critical role in the regulation of gait in older adults, especially under complex and challenging conditions, and that EF deficits may, therefore, contribute to fall risk. The objective of this study was to evaluate if reduced EF is a risk factor for future falls over the course of 5 years of follow-up. Secondary objectives were to assess whether single and dual task walking abilities, an alternative window into EF, were associated with fall risk. We longitudinally followed 256 community-living older adults (age: 76.4±4.5 yrs; 61% women) who were dementia free and had good mobility upon entrance into the study. At baseline, a computerized cognitive battery generated an index of EF, attention, a closely related construct, and other cognitive domains. Gait was assessed during single and dual task conditions. Falls data were collected prospectively using monthly calendars. Negative binomial regression quantified risk ratios (RR). After adjusting for age, gender and the number of falls in the year prior to the study, only the EF index (RR: .85; CI: .74-.98, p = .021), the attention index (RR: .84; CI: .75-.94, p = .002) and dual tasking gait variability (RR: 1.11; CI: 1.01-1.23; p = .027) were associated with future fall risk. Other cognitive function measures were not related to falls. Survival analyses indicated that subjects with the lowest EF scores were more likely to fall sooner and more likely to experience multiple falls during the 66 months of follow-up (p<0.02). These findings demonstrate that among community-living older adults, the risk of future falls was predicted by performance on EF and attention tests conducted 5 years earlier. The present results link falls among older adults to cognition, indicating that screening EF will likely enhance fall risk assessment, and that treatment of EF may reduce fall risk.

    The clinical consequences of whiplash injuries resulting from a motor vehicle accident (MVA) are poorly understood. Thereby, there is general lack of research on the development of disability in patients with acute and chronic Whiplash Associated Disorders. The objective is to describe the design of an inception cohort study with a 1-year follow-up to determine risk factors for the development of symptoms after a low-impact motor vehicle accident, the prognosis of chronic disability, and costs. Victims of a low-impact motor vehicle accident will be eligible for participation. Participants with a Neck Disability Index (NDI) score of 7 or more will be classified as experiencing post-traumatic neck pain and will enter the experimental group. Participants without complaints (a NDI score less than 7) will enter the reference group. The cohort will be followed up by means of postal questionnaires and physical examinations at baseline, 3 months, 6 months, and 12 months. Recovery from whiplash-associated disorders will be measured in terms of perceived functional health, and employment status (return to work). Life tables will be generated to determine the 1-year prognosis of whiplash-associated disorders, and risk factors and prognostic factors will be assessed using multiple logistic regression analysis. Little is known about the development of symptoms and chronic disability after a whiplash injury. In the clinical setting, it is important to identify those people who are at risk of developing chronic symptoms.This inception prospective cohort study will provide insight in the influence of risk factors, of the development of functional health problems, and costs in people with whiplash-associated disorders.

    The purpose of this study was to demonstrate the impact of bilateral free flap breast reconstruction on the abdominal wall. This is the second installation of a two-part series. Presented here are bilateral combinations of three techniques: the muscle-sparing free transverse rectus abdominis musculocutaneous (TRAM) flap, deep inferior epigastric perforator (DIEP) flap, and superficial inferior epigastric artery (SIEA) flap. A blinded prospective cohort study was performed involving 234 patients. Patients were evaluated preoperatively and for 1 year postoperatively. At each encounter, patients underwent objective abdominal strength testing using the Manual Muscle Function Test and Functional Independence Measure and psychometric testing using the Short Form 36 questionnaire. At postoperative visits, patients also completed a questionnaire specific to breast reconstruction. Statistical analysis included the Kruskal-Wallis, Mann-Whitney, Friedman, and Wilcoxon signed rank tests. A total of 234 patients were enrolled. Of these, 157 underwent reconstruction, 82 of which were bilateral. There was a significant decline in upper (p=0.02) and lower (p=0.05) abdominal strength from bilateral free TRAM flaps compared with bilateral DIEP flaps. Likewise, there was a significant decline in upper (p=0.055) and lower (p=0.04) abdominal strength from bilateral free TRAM flaps compared with bilateral SIEA flaps. For combinations, the most muscle impairment to least was as follows: free TRAM/free TRAM, free TRAM/DIEP, DIEP/DIEP, DIEP/SIEA, and SIEA/SIEA. The free TRAM/SIEA data were not significant. Although psychometric testing showed trends, there was no significant difference among treatment groups. Abdominal wall strength following various combinations of bilateral free flap breast reconstruction techniques closely adheres to theoretical predictions based on the degree of surgical muscle sacrifice.

    We aimed to evaluate the anatomical and functional outcomes of posterior intravaginal slingplasty (P-IVS) for the treatment of a vaginal vault or uterine prolapse (VP/UP). This was a 12-month prospective, multicenter, observational study. Women aged over 30 years who presented with stage II or greater VP/UP underwent P-IVS by four urologists at four university hospitals. Preoperatively, pelvic examination by use of the Pelvic Organ Prolapse Quantification (POP-Q) system, the Pelvic Floor Distress Inventory (PFDI) questionnaire, the 3-day frequency volume chart, and uroflowmetry were completed. At the 12-month follow-up, changes in the POP-Q, PFDI, frequency volume chart, and uroflowmetry parameters were assessed. Cure was defined as VP/UP stage 0 and improvement as stage I. The cure and improvement rates among the 32 women were 65.6% and 34.4%, respectively. All subscale scores of the Urinary Distress Inventory, the general subscale score of the Pelvic Organ Prolapse Distress Inventory, and the rectal prolapse subscale score of the Colo-Rectal-Anal Distress Inventory were significantly improved. There were no significant changes in the frequency volume chart or uroflowmetry parameters. There was one case of surgery-related transfusion. Trans-vaginal repair by P-IVS is an effective and safe procedure for restoring the anatomical defect and improving the associated pelvic floor symptoms in women with VP/UP.

    2014-01-01

    Introduction Cystatin C (Cysc) could be affected by thyroid function both in vivo and in vitro and thereby may have limited ability to reflect renal function. We aimed to assess the association between Cysc and thyroid hormones as well as the effect of thyroid function on the diagnostic accuracy of Cysc to detect acute kidney injury (AKI). Methods A total of 446 consecutive intensive care unit (ICU) patients were screened for eligibility in this prospective AKI observational study. Serum Cysc, thyroid hormones and serum creatinine (Scr) were measured upon entry to the ICU. We also collected each patient's baseline characteristics including the Acute Physiology and Chronic Health Evaluation II (APACHE-II) score. The diagnostic performance of Cysc was assessed from the area under the receiver operator characteristic curve (AUC) in each quartile of thyroid hormone(s). Results A total of 114 (25.6%) patients had a clinical diagnosis of AKI upon entry to the ICU. The range of free thyroxine (FT4) value was 4.77 to 39.57 pmol/L. Multivariate linear regression showed that age (standardized beta = 0.128, P < 0.0001), baseline Scr level (standardized beta = 0.290, P < 0.0001), current Scr (standardized beta = 0.453, P < 0.0001), albumin (standardized beta = -0.086, P = 0.006), and FT4 (standardized beta = 0.062, P = 0.039) were related with Cysc. Patients were divided into four quartiles based on FT4 levels. The AUC for Cysc in detecting AKI in each quartile were as follows: 0.712 in quartile I, 0.754 in quartile II, 0.829 in quartile III and 0.797 in quartile IV. There was no significant difference in the AUC between any two groups (all P > 0.05). The optimal cut-off value of Cysc for diagnosing AKI increased across FT4 quartiles (1.15 mg/L in quartile I, 1.15 mg/L in quartile II, 1.35 mg/L in quartile III and 1.45 mg/L in quartile IV). Conclusions There was no significant impact of thyroid function on the diagnostic accuracy

    Introduction Management of unstable intertrochanteric fractures have posed a unique challenge to orthopaedicians over years. Several surgical techniques and implants have been developed for the same. Fractures of the lateral wall have been considered as the major cause of femoral medialization after fixation by Dynamic Hip Screw (DHS). Studies have shown that supplementation of trochanteric stabilization plate reduces the incidence of femoral medialization. Aim To assess the radiological union and hip function after fixation of unstable intertrochanteric fractures with DHS and Trochanteric Stabilization Plate (TSP). Materials and Methods A prospective study was conducted with a total of 32 patients between age groups of 30-70 years with Evan Jensen unstable and very unstable type of intertrochanteric fractures, between August 2013 to March 2015 in the Department of Orthopaedics ARS Hospital, Tirupur, Tamil Nadu, India. They underwent open reduction and DHS and TSP fixation. They were started on full weight bearing mobilization on post op day three. They were reviewed at post-op weeks 3,6,12 and 24. Hip mobilization and rehabilitation exercises were instituted during course of reviews. Radiographs were taken to assess fracture union and hip function was evaluated during follow-ups. At the end of 24 weeks, degree of radiographic union was scored as per Radiological Union Score for Hip (RUSH). Hip function was scored with Harris hip score. Analyses were done using frequency and proportions. Chi-square tests were used to assess the test of association. Results Fifteen patients had RUSH scores between 10-20 and 17 patients had scores between 20-30 points. RUSH score had mean of 21.03+/- 2.132 points. 9 of 32 patients had excellent results as per Harris hip score, 10 had good, nine had fair and four had poor. On comparison of Harris hip score with RUSH score: Interval between 10-20 points, of 15 patients; two had excellent results, five had good, five had fair and three

    Background: Alzheimer’s disease (AD) is the most prevalent degenerative disorder of the brain among elderly individuals. Many studies indicate that oxidative stress is an important pathogenic factor which involves oxidizing macromolecules such as DNA, lipids, and proteins in AD. Green tea is a rich source of antioxidant compounds that can remove radical oxygen species. The purpose of this study was to investigate the influence of green tea consumption on markers of oxidative stress in AD. Methods: In this prospective intervention study, 30 patients with severe AD were recruited. The diagnosis of AD was made based on the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer’s disease and Related Disorders Association (NINCDS/ADRDA) criteria. Brain magnetic resonance imaging (MRI) and computed tomography (CT) scan as well as Mini-Mental State Examination (MMSE) were performed for all participants in which four green tea pills were administered daily for 2 months (2 g/day in 2 divided doses). The plasma total antioxidant capacity, 8-hydroxy-2’-deoxyguanosine levels (8-OHdG), malondialdehyde (MDA), carbonyl content, and MMSE scores were measured at baseline and at the end of the study period. Results: The levels of MDA, 8-OHdG and carbonyl decreased significantly as compared to baseline values (P=0.002, P=0.001 and P=0.037, respectively). Whereas, the total antioxidant capacity of plasma and MMSE scores significantly increased at end point (P=0.000, P=0.043, respectively). Conclusion: The findings indicate that consumption of green tea for two months by with the improvement of antioxidant system exerts beneficial effect on cognitive function. PMID:27757204

    Background: Although esthetic rhinoplasty has many advantages, it might lead to some complications as well. The literature includes scarce and severely controversial studies on these issues, and there is no research on complications of cosmetic closed rhinoplasty. In addition, some complications are not assessed after any rhinoplasty types. Besides, there is no investigation on the outcome of rhinoplasty carried out by graduate students. The purpose of this study was to determine these. Materials and Methods: In this preliminary prospective cohort study, 96 healthy patients underwent closed esthetic rhinoplasty by senior residents of otolaryngology and maxillofacial surgery at Taleghani Hospital (Tehran, 2004-2006). Afterward, at 11 follow-up sessions (the 1st, 2nd, 3rd, 4th, 6th, 8th, 10th, 12th, 16th, 20th, and 24th postoperative weeks), five functional complications (hyposmia/anosmia, nasal obstruction, unpleasant voice changes, recurrent colds, and synechiae) were questioned/examined. The presence of a symptom during at least four subsequent sessions (without elimination until the sixth postoperative month) and the appearance of synechiae in any session were regarded as positive. The data were assessed using Spearman's correlation coefficient (α = 0.05). Results: The incidence rates of synechiae, nasal obstruction, unpleasant voice changes, hyposmia/anosmia, and recurrent colds were 56.25%, 37.5%, 0%, 1.04%, and 29.17%, respectively. No statistically significant relationship was found between the complications with age, gender, or the surgeon's specialty (P > 0.05), but the correlation with home care compliance was significant (ρ = –0.29, P = 0.01). Conclusions: High complication rates were observed in both residency programs. Failure to follow home care instructions might prevent/delay recovery. Further in-depth studies are needed to assess this. PMID:23878567

    To determine the effect of fall-related concerns on physical, mental, and social function. Community-based prospective cohort study (secondary analysis using control group data from a randomized controlled trial). Two municipalities in the south of the Netherlands. Community-dwelling older adults (N = 260). Two groups were created using Modified Falls Efficacy Scale scores (high and low levels of fall-related concerns). Five outcome measures representing physical, mental, and social function were included: activities of daily living (ADLs), symptoms of depression, feelings of anxiety, social participation, and social support interactions. Outcomes were measured at baseline and at 2, 8, and 14 months. Data were analyzed using analysis of covariance and mixed-effect regression models for longitudinal data, adjusting for age, sex, living status (alone or with another person), educational level, cognitive status, self-perceived health, and falls history at baseline. At baseline, significantly more limitations in ADLs and social participation were found for older persons with high levels of fall-related concerns than for those with low levels of concern. These differences persisted over 14 months of follow-up and were consistent over time. No significant differences were found for symptoms of depression, feelings of anxiety, or social support interactions, except for feelings of anxiety at 14 months. Older persons with higher levels of fall-related concerns reported up to 14 months poorer ADL and social participation for up to 14 months than those with lower levels of fall-related concerns. From a clinical point of view, the clear relationship between fall-related concerns and ADL dysfunction and social participation may help to target groups who are at risk of developing adverse consequences of concerns about falls. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

    Background The relationship between hyperuricemia and chronic kidney disease (CKD) has been found in various observational studies. Although hypouricemia is associated with cardiovascular events, it has not been established as a risk factor for CKD. We investigated the relationship between serum uric acid level and the loss of kidney function and incident CKD in healthy people. Materials and Methods Healthy people were enrolled in this community-based prospective cohort study, the Saitama Cardiometabolic Disease and Organ Impairment Study, Japan. The analysis was conducted on 4188 subjects followed up for at least 3 years, 3102 for 6 years and 1052 for 9 years. Their data including glomerular filtration rate (eGFR) decline were examined every three years. The outcome event was incident CKD or the decrease in eGFR by more than 25% in three years. Multivariate statistical models were adjusted for the baseline characteristics. Results The following data was obtained: mean±SD age, male, 39.6±10.4 years, female 38.4±10.8 years; eGFR, male, 81.9±16.4 ml/min/1.73m2, female, 82.1±17.5 ml/min/1.73m2; serum uric acid level, male, 5.8±1.2 mg/dl, female, 4.1±0.9 mg/dl. Both low and high serum uric acid levels were associated with the outcome and eGFR decline in males (multivariate logistic additional additive models, linear p = 0.0001, spline p = 0.043; generalized additive models, linear p = 0.0001, spline p = 0.012). In subjects with low serum uric acid levels (male, <5 mg/dl; female, <3.6 mg/dl), multivariate linear mixed models showed that low serum uric acid levels were associated with eGFR decline in a time-dependent manner (male, p = 0.0001; female, p = 0.045). Conclusion This study showed that low as well as high levels of uric acid are associated with the loss of kidney function. Hypouricemia is a candidate predictor of kidney function decline in healthy people. PMID:25658588

    To better understand the role earlier stressful environments have in predicting functional somatic symptoms (FSS) in late adolescence, this study explores the effect the occurrence of earlier changes in family dynamics and friendship conflict have on FSS. We used data from the Consortium for Longitudinal Studies on Child Abuse and Neglect (N = 1,314), a large, prospective study of children at risk for maltreatment and their parent/caregiver from approximately 4 to 18 years of age. We found a significant, small (Effect Size = .10), positive association between the frequency of family dynamic change during middle childhood (ages 6-12 years) and FSS at age 18 but not during middle adolescence (ages 14 and 16). Conflict with a same-sex best friend at age 16 moderated the association between the frequency of change and FSS. The frequency of family dynamic change in middle childhood and middle adolescence was associated with greater FSS among those who reported greater conflict but not for those who reported experiencing lower conflict. Overall, these effects were specific to friendship conflict and remained when other friendship processes (intimacy and companionship) were included, did not generalize to anxiety/depressive symptoms, and predicted FSS without comorbid anxiety/depressive symptoms. No gender differences were found. The change-conflict interaction differed according to type of family dynamic change (parental vs. residential). Findings emphasize how earlier exposure to frequent changes in family dynamics in middle childhood is particularly associated with late-adolescent health, especially in the context of greater friendship conflict.

    Abstract Background Although muscle mass declines with testosterone deficiency in men, previous studies of muscle function have not demonstrated consistent deficits, likely due to relatively insensitive methodology. Our objective was to determine the effects of testosterone deprivation on the biomechanical function of individual lower‐limb muscles. Methods We conducted a 12‐month prospective, observational case–control study of 34 men newly commencing androgen deprivation treatment (ADT) for prostate cancer and 29 age‐matched prostate cancer controls. Participants were assessed at 0, 6, and 12 months while walking in a biomechanics laboratory. We combined video‐based motion capture and ground reaction force data with computerized musculoskeletal modelling to assess the following primary outcomes: (i) peak joint torques at the hip, knee and ankle, and corresponding individual muscle forces; (ii) individual muscle contributions to acceleration of the body's centre of mass; and (iii) walking speed, stride length, and step width. A linear mixed model was used to compare mean differences between groups. Results Compared with controls over 12 months, men receiving ADT had a mean reduction in total testosterone level from 14.1 to 0.4 nmol/L, and demonstrated more marked decreases in peak hip flexor torque by 14% [mean difference −0.11 N/kg (−0.19, −0.03), P = 0.01] and peak knee extensor torque by 16% [−0.11 N/kg (−0.20, −0.02), P = 0.02] of the initial mean value. Correspondingly, iliopsoas force decreased by 14% (P = 0.006), and quadriceps force decreased by 11%, although this narrowly missed statistical significance (P = 0.07). Soleus decreased contribution to forward acceleration of the body's centre of mass by 17% [mean difference −0.17 m/s2 (−0.29, −0.05), P < 0.01]. No significant changes between groups were observed in other joint torques or individual muscle contributions to acceleration of the body

    Long-term acute care hospitals (LTACHs) have emerged for patients requiring medical care beyond a short stay. Minimal data have been reported on functional outcomes in this setting. The purposes of this study were: (1) to measure the clinical utility of the Functional Status Score for the Intensive Care Unit (FSS-ICU) in an LTACH setting and (2) to explore the association between FSS-ICU score and discharge setting. Data were obtained from 101 patients (median age=70 years, interquartile range [IQR]=61-78; 39% female, 61% male) who were admitted to an LTACH. Participants were categorized into 1 of 5 groups by discharge setting: (1) home (n=14), (2) inpatient rehabilitation facility (n=26), (3) skilled nursing facility (n=23), (4) long-term care/hospice/expired (n=13), or (5) transferred to a short-stay hospital (n=25). Data were prospectively collected from a 38-bed LTACH in the United States over 8 months beginning in September 2010. Functional status was scored using the FSS-ICU within 4 days of admission and every 2 weeks until discharge. The FSS-ICU consists of 5 categories: rolling, supine-to-sit transfers, unsupported sitting, sit-to-stand transfers, and ambulation. Each category was rated from 0 to 7, with a maximum cumulative FSS-ICU score of 35. Cumulative FSS-ICU scores significantly improved from a median (IQR) of 9 (3-17) to 14 (5-24) at discharge. Median (IQR) cumulative discharge FSS-ICU scores were significantly different among the discharge categories: home=28 (22-32), inpatient rehabilitation facility=21 (15-24), skilled nursing facility=14 (8-21), long-term care/hospice/expired=5 (0-11), and transfer to a short-stay hospital=4 (0-7). Patients receiving therapy at an LTACH demonstrate significant improvements from admission to discharge using the FSS-ICU. This outcome tool discriminates among discharge settings and successfully documents functional improvements of patients in an LTACH setting.

    Low maternal thyroid function during early pregnancy is associated with various adverse outcomes including impaired neurocognitive development of the offspring, premature delivery and abnormal birthweight. To aid doctors in the risk assessment of thyroid dysfunction during pregnancy, we set out to investigate clinical risk factors and derive a prediction model based on easily obtainable clinical variables. In total, 9767 women during early pregnancy (≤18 week) were selected from two population-based prospective cohorts: the Generation R Study (N = 5985) and the ABCD study (N = 3782). We aimed to investigate the association of easily obtainable clinical subject characteristics such as maternal age, BMI, smoking status, ethnicity, parity and gestational age at blood sampling with the risk of low free thyroxine (FT4) and elevated thyroid stimulating hormone (TSH), determined according to the 2·5th-97·5th reference range in TPOAb negative women. BMI, nonsmoking and ethnicity were risk factors for elevated TSH levels; however, the discriminative ability was poor (range c-statistic of 0·57-0·60). Sensitivity analysis showed that addition of TPOAbs to the model yielded a c-statistic of 0·73-0·75. Maternal age, BMI, smoking, parity and gestational age at blood sampling were risk factors for low FT4, which taken together provided adequate discrimination (range c-statistic of 0·72-0·76). Elevated TSH levels depend predominantly on TPOAb levels, and prediction of elevated TSH levels is not possible with clinical characteristics only. In contrast, the validated clinical prediction model for FT4 had high discriminative value to assess the likelihood of low FT4 levels. © 2016 John Wiley & Sons Ltd.

    Immediate/early implant function means great benefits for patients and therapists because treatment time and cost can be substantially reduced. This concept has become an accepted alternative for complete arch fixed restorations in the mandible, and clinical documentation is emerging for other indications. The purpose of this prospective clinical multicenter study was to evaluate the outcome of implants placed in incisor, canine, and premolar regions in maxillas or mandibles. Implants were loaded with provisional crowns and bridges on the same day or within a few days and were followed up for 1 year during function. Four centers treated 76 patients each in need of an implant-retained prosthesis in the anterior and premolar regions in the maxilla or mandible. A total of 116 titanium implants with machined surfaces (Brånemark System , Nobel Biocare AB, Gothenburg, Sweden) were placed: 74 in maxillas and 42 in mandibles. Eighty-seven prostheses were made, of which 63 were single crowns and 24 were bridges (supported by 53 splinted implants). Twenty-two implants in 14 patients were placed in fresh extraction sites. The goal with the preparation and insertion technique was to achieve good primary implant stability and a minimum implant insertion torque of 30 Ncm before the implant was completely seated. The occlusion was adjusted to eliminate direct contact with the provisional prostheses. After 6 months, the patients received their permanent prostheses. Sixty-seven patients were followed for 1 year. Five implants were lost in five patients, three in the maxilla and two in the mandible. Four of the lost implants were single-tooth replacements and one was splinted. The cumulative survival rate (CSR) was 95.7% for all implants after 1 year and 93.7% and 98.1% for single-tooth and splinted implants, respectively. There were no implant losses in the extraction sites. The CSR of 96% at 1 year indicates that immediate function of Brånemark System implants placed in incisor

    To assess rotator cuff rupture characteristics and evaluate healing and the functional outcome after arthroscopic repair in patients older than 70 years versus patients younger than 50 years. We conducted a multicenter, prospective, comparative study of 40 patients younger than 50 years (group A) and 40 patients older than 70 years (group B) treated with arthroscopic rotator cuff repair. Patients older than 70 years were operated on only if symptoms persisted after 6 months of conservative treatment, whereas patients younger than 50 years were operated on regardless of any persistent symptoms. Imaging consisted of preoperative magnetic resonance imaging and postoperative ultrasound. Preoperative and postoperative function was evaluated with Constant and modified Constant scores. Patient satisfaction was also assessed. The evaluations were performed at least 1 year postoperatively. No patient was lost to follow-up. The incidence of both supraspinatus and infraspinatus tears was greater in group B. Greater retraction in the frontal plane and greater fatty infiltration were observed in group B. The Constant score was significantly improved in both groups (51 ± 12.32 preoperatively v 77.18 ± 11.02 postoperatively in group A and 48.8 ± 10.97 preoperatively v 74.6 ± 12.02 postoperatively in group B, P < .05). The improvement was similar in both groups. The modified Constant score was also significantly improved in both groups (57.48 ± 18.23 preoperatively v 81.35 ± 19.75 postoperatively in group A and 63.09 ± 14.96 preoperatively v 95.62 ± 17.61 postoperatively in group B, P < .05). The improvement was greater for group B (P < .05). Partial rerupture of the rotator cuff occurred in 2 cases in group A and 5 cases in group B. Complete rerupture was observed in 2 patients in group B. In group A, 29 patients (72.5%) were very satisfied, 8 (20%) were satisfied, and 3 (7.5%) were less satisfied. In group B, 33 patients (82.5%) were very satisfied, 6 (15%) were

    Background Biomass smoke is associated with the risk of chronic obstructive pulmonary disease (COPD), but few studies have elaborated approaches to reduce the risk of COPD from biomass burning. The purpose of this study was to determine whether improved cooking fuels and ventilation have effects on pulmonary function and the incidence of COPD. Methods and Findings A 9-y prospective cohort study was conducted among 996 eligible participants aged at least 40 y from November 1, 2002, through November 30, 2011, in 12 villages in southern China. Interventions were implemented starting in 2002 to improve kitchen ventilation (by providing support and instruction for improving biomass stoves or installing exhaust fans) and to promote the use of clean fuels (i.e., biogas) instead of biomass for cooking (by providing support and instruction for installing household biogas digesters); questionnaire interviews and spirometry tests were performed in 2005, 2008, and 2011. That the interventions improved air quality was confirmed via measurements of indoor air pollutants (i.e., SO2, CO, CO2, NO2, and particulate matter with an aerodynamic diameter of 10 µm or less) in a randomly selected subset of the participants' homes. Annual declines in lung function and COPD incidence were compared between those who took up one, both, or neither of the interventions. Use of clean fuels and improved ventilation were associated with a reduced decline in forced expiratory volume in 1 s (FEV1): decline in FEV1 was reduced by 12 ml/y (95% CI, 4 to 20 ml/y) and 13 ml/y (95% CI, 4 to 23 ml/y) in those who used clean fuels and improved ventilation, respectively, compared to those who took up neither intervention, after adjustment for confounders. The combined improvements of use of clean fuels and improved ventilation had the greatest favorable effects on the decline in FEV1, with a slowing of 16 ml/y (95% CI, 9 to 23 ml/y). The longer the duration of improved fuel use and ventilation, the greater

    To assess changes over time and responsiveness of the Cochin Hand Function Scale (CHFS) and Mouth Handicap In Systemic Sclerosis (MHISS) scale in patients with systemic sclerosis (SSc). This was a prospective longitudinal study. Participants were drawn from a convenience sample of individuals with SSc, who were attending the annual Congress of the Association des Sclérodermiques de France, the French SSc patients' association. Participants were evaluated twice by the CHFS, MHISS scale, Health Assessment Questionnaire, McMaster-Toronto Arthritis Patient Preference Disability Questionnaire, and other outcome measures. Differences in measures over time were evaluated using the Wilcoxon signed rank test. Responsiveness was assessed by the effect size and standardized response mean. Nonparametric Spearman rank correlation (r) was used to assess correlation between outcome measures. Forty-nine patients were assessed. The CHFS and MHISS scores worsened over time (mean [SD] differences 2.7 [10.7], P = 0.08, and 3.5 [9.8], P = 0.14, respectively). The CHFS effect size and standardized response mean values were -0.16 and -0.24, respectively, and MHISS values were -0.53 and -0.52, respectively. The correlation between change in the CHFS score and change in Health Assessment Questionnaire and McMaster-Toronto Arthritis Patient Preference Disability Questionnaire scores was fair to moderate, whereas changes in MHISS score were poorly or not correlated to other measures. For patients considering their state deteriorated, the MHISS scale was the most responsive instrument. The CHFS and MHISS scores may be useful in detecting changes in location-specific limitations in activity for SSc patients.

    Thyroid hormone is involved in the regulation of early brain development. Since the fetal thyroid gland is not fully functional until week 18-20 of pregnancy, neuronal migration and other crucial early stages of intrauterine brain development largely depend on the supply of maternal thyroid hormone. Current clinical practice mostly focuses on preventing the negative consequences of low thyroid hormone concentrations, but data from animal studies have shown that both low and high concentrations of thyroid hormone have negative effects on offspring brain development. We aimed to investigate the association of maternal thyroid function with child intelligence quotient (IQ) and brain morphology. In this population-based prospective cohort study, embedded within the Generation R Study (Rotterdam, Netherlands), we investigated the association of maternal thyroid function with child IQ (assessed by non-verbal intelligence tests) and brain morphology (assessed on brain MRI scans). Eligible women were those living in the study area at their delivery date, which had to be between April 1, 2002, and Jan 1, 2006. For this study, women with available serum samples who presented in early pregnancy (<18 weeks) were included. Data for maternal thyroid-stimulating hormone, free thyroxine, thyroid peroxidase antibodies (at weeks 9-18 of pregnancy), and child IQ (assessed at a median of 6·0 years of age [95% range 5·6-7·9 years]) or brain MRI scans (done at a median of 8·0 years of age [6·2-10·0]) were obtained. Analyses were adjusted for potential confounders including concentrations of human chorionic gonadotropin and child thyroid-stimulating hormone and free thyroxine. Data for child IQ were available for 3839 mother-child pairs, and MRI scans were available from 646 children. Maternal free thyroxine concentrations showed an inverted U-shaped association with child IQ (p=0·0044), child grey matter volume (p=0·0062), and cortex volume (p=0·0011). For both low and high

    In recent years, functionalization of carbon nanotubes (CNTs) with biomolecules such as nucleotide acids, proteins, and polymers as well as cells have emerged as a new exciting field. Theoretical and experimental studies of structure and function of bio-inspired CNT composites have made great advances. The importance of nucleic acids, proteins, and polymers to the fundamental developments in CNT-based bio-nano-composites or devices has been recognized. In particular, biomechanics, biochemistry, thermodynamics, electronic, optical, and magnetic properties of the bio-inspired CNT composites have become a new interdisciplinary frontier in life science and nanomaterial science. Here we review some of the main advances in this field over the past few years, explore the application prospects, and discuss the issues, approaches, and challenges, with the aim of stimulating a broader interest in developing CNT-based bio-nanotechnology.

  7. The Dynamic Relationship Between Cognitive Function and Positive Well-Being in Older People: A Prospective Study Using the English Longitudinal Study of Aging

    PubMed Central

    2014-01-01

    There is evidence that having a stronger sense of positive well-being may be a potential resource for healthier aging as represented by slower physical decline, reduced risk of frailty and longer survival. However, it is unclear whether positive well-being is protective of another crucial component of healthy aging, cognitive function, or whether it has a bidirectional relationship with cognitive function. We use multilevel models with within-person centering to estimate the within- and between-person association between cognitive function and positive well-being in 4 waves of data from the English Longitudinal Study of Ageing (ELSA), (N = 10985, aged 50–90 years at wave 1). Our findings show that, although most variation in cognitive function was explained by age, and most variation in well-being was explained by depression, small but significant associations between cognition and well-being remained after variation in age and depression were controlled. In models where cognition was the outcome, the association was mainly because of variation in mean levels of well-being between persons. In models where well-being was the outcome, the association was mainly because of within-person fluctuation in cognitive test performance. Exercise and depression were the most important moderating influences on the association between cognition and positive well-being. Depression had greater effect upon this association for those with higher well-being, but exercise protected cognitive performance against the adverse effects of lower well-being. PMID:24955999

    Heart failure with normal left ventricular ejection fraction (HFNEF) accounts for about one third of all heart failure patients with considerable mortality. The metabolic syndrome (MS) is a risk factor for diastolic dysfunction and HFNEF. We hypothesized that modifying metabolic burden by exercise training and weight loss might improve left ventricular diastolic function, heart failure symptoms and rehospitalization rate. Forty patients with HFNEF, MS and prediabetes were enrolled in this prospective study. Echocardiography and cardiopulmonary exercise testing (CPET) were done at baseline and after 3 months lifestyle modification (LSM). NT-pro BNP and adiponectin were determined at baseline as both peptidehormones play a crucial role in MS and heart failure. After discharge a 3-month LSM program with the aim of weight reduction by diet and exercise was started. After the intervention period a weight reduction of ≥ 2% was defined as successful LSM (group A = 23 patients), while a weight reduction < 2% was classified as unsuccessful LSM (group B = 17 patients). At baseline NT-pro BNP (424 ± 381 versus 121 ± 99 pg/ml, P < 0.01) and adiponectin (10.1 ± 6.2 versus 4.6-2.0 µg/ml, P < 0.01) were higher in group A than in group B. After 3 months of LSM, CPET showed a significant improve- ment of VO2 peak (P < 0.01), EqCO2 (P < 0.001), O2-pulse (P = 0.02) and VE / VCO2 slope (P = 0.01) in group A. After one year of follow-up a modest but significant reduction of left atrial size and mitral flow to mitral annulus velocity ratio E/E' was seen in group A. LSM resulted in significant improvement of NYHA status (P = 0.03) and higher freedom of rehospitalization (P = 0.04) in group A. Successful lifestyle modification in obese, prediabetic patients with HFNEF improves diastolic left ventricular function and cardiopulmonary exercise capacity. As these measures result in improved NYHA status and less hospitalization, LSM might be a promising approach to prevent chronic

Prospective longitudinal cohort study. 150 preterm children (born at < 30 weeks' gestation) and 151 term-born children (born at > 36 completed weeks' gestation and weighing > 2499g) admitted to the Royal Women's Hospital, Melbourne, were recruited at birth and will be invited to participate in a 5-year follow-up study. This study will examine previously collected data (from birth to 2 years) that comprise detailed motor assessments, and structural and functional brain MRI images. At 5 years, preterm and term, children will be examined using comprehensive motor assessments, including: the Movement Assessment Battery for Children (2nd edition) and measures of gait function through spatiotemporal (assessed with the GAITRite® Walkway) and dynamic postural control (assessed with Microsoft Kinect) variables; and hand grip strength (assessed with a dynamometer); and measures of physical activity (assessed using accelerometry), cognitive development (assessed with Wechsler Preschool and Primary Scale of Intelligence), and emotional and behavioural status (assessed with the Strengths and Difficulties Questionnaire and the Developmental and Wellbeing Assessment). At the 5-year assessment, parents/caregivers will be asked to complete questionnaires on demographics, physical activity, activities of daily living, behaviour, additional therapy (eg, physiotherapy and occupational therapy), and motor function (assessed with Pediatric Evaluation of Disability Inventory, Pediatric Quality of Life Questionnaire, the Little Developmental Co-ordination Questionnaire and an activity diary). For the primary aim, the prevalence of motor impairment from birth to 5 years will be compared between children born at < 30 weeks and at term, using the proportion of children classified as abnormal at each of the time points (term age, 1, 2 and 5 years).

    Numerous high quality studies have shown the positive effects of various osteoporotic medical treatment regimens on bone mass and on the reduction of risk for new spinal, hip and non-spinal fractures in osteoporotic patients. However, the effect of osteoporotic treatment on the functional and clinical outcome of patients who have sustained hip fractures and been treated surgically has not yet been addressed. Five hundred and twenty patients out of 611 who were admitted (2009-2011), operated on due to a hip fracture and completed their follow-up evaluations were included in this study. Data related to functional outcome scores, re-fracture rate, quality of life and mortality rate were prospectively recorded, analysed and correlated to osteoporotic medical treatment. There were 151 (25%) men and 369 (71%) women with a mean age of 80.7 years (range, 60 to 90 years). At a mean follow-up of 27.5 months (range, 24 to 36 months) a mortality rate of 23.6% at 2 years was recorded. Mean values of functional and quality of life scores were found to have progressively improved within two years after surgery. Seventy-eight (15%) patients were taking osteoporotic treatment before their hip fracture and 89 (17.1%) started afterwards. Osteoporotic treatment proved to be an important predictor of functional recovery (all p values<0.05), re-fracture rate (p=0.028) and quality of life (EQ-5D, all dimensions, p values<0.05). Osteoporotic treatment did not affect post-fracture mortality rates. Osteoporotic treatment taken before or initiated after fracture is a strong predictor of functional and clinical outcome in patients with hip fractures treated surgically. Copyright © 2014.

  11. Prospects for Optogenetic Augmentation of Brain Function.

    The ability to optically control neural activity opens up possibilities for the restoration of normal function following neurological disorders. The temporal precision, spatial resolution, and neuronal specificity that optogenetics offers is unequalled by other available methods, so will it be suitable for not only restoring but also extending brain function? As the first demonstrations of optically "implanted" novel memories emerge, we examine the suitability of optogenetics as a technique for extending neural function. While optogenetics is an effective tool for altering neural activity, the largest impediment for optogenetics in neural augmentation is our systems level understanding of brain function. Furthermore, a number of clinical limitations currently remain as substantial hurdles for the applications proposed. While neurotechnologies for treating brain disorders and interfacing with prosthetics have advanced rapidly in the past few years, partially addressing some of these critical problems, optogenetics is not yet suitable for use in humans. Instead we conclude that for the immediate future, optogenetics is the neurological equivalent of the 3D printer: its flexibility providing an ideal tool for testing and prototyping solutions for treating brain disorders and augmenting brain function.

    Background: Surgical treatment of complicated colonic diverticular disease is still debatable. The aim of this prospective study was to evaluate the outcome of laparoscopic sigmoid colectomy in patients with diverticulitis. Patients offered laparoscopic surgery presented with acute complicated diverticulitis (Hinchey type I, II, III), chronically recurrent diverticulitis, bleeding, or sigmoid stenosis caused by chronic diverticulitis. Method: All patients who underwent laparoscopic colectomy within a 12-year period were prospectively entered into a database registry. One-stage laparoscopic resection and primary anastomosis constituted the planned procedure. A 4-trocar approach with suprapubic minilaparotomy was performed. Main data recorded were age, sex, postoperative pain, return of bowel function, operation time, duration of hospital stay, and early and late complications. Results: During the study period, 260 sigmoid colectomies were performed for diverticulitis. The cohort included 104 male and 156 female patients; M to F ratio was 4:6. Postoperative pain was controlled by NSAIDs or weak opioid analgesia. Fifteen patients (5.7%) required conversion from laparoscopic to open colectomy. The most common reasons for conversion were directly related to the inflammatory process, abscess, and peritonitis. Mean operative time was 130±54. Average postoperative hospital stay was 10±3 days. A longer hospital stay was recorded for Hinchey type IIb patients. Complications were recorded in 30 patients (11.5%). The most common complications that required reoperation were hemorrhage in 2 patients (0.76) and anastomotic leak in 5 patients (only 3 of them required reoperation). The mortality among them was 2 patients (0.76%). Conclusions: Laparoscopic surgery for diverticular disease is safe, feasible, and effective. Therefore, laparoscopic colectomy has replaced open resection as standard surgery for recurrent and complicated diverticulitis at our institution. PMID:21605507

    A few studies have examined change in cognitive performance by diabetes status with disparate results. We examined the 4-year change in cognitive performance among older adults according to glucose tolerance status. Three cognitive tests (Mini-Mental State Examination, Verbal Fluency [VF] test, and Trail-Making Test B) were measured 4 years apart in 999 white men and women aged 42 to 89 years, who were enrolled in the Rancho Bernardo Study. Participants were classified with normal (NGT), impaired (IGT) or diabetic glucose tolerance. Sex-specific linear regression models adjusted for age, education, depression score, apolipoprotein E epsilon4 allele, and current estrogen use. We checked for mediation by further adjusting for total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglyceride levels; blood pressure; glycohemoglobin level; and microalbuminuria, retinopathy, stroke, or coronary heart disease. At baseline, mean cognitive function scores did not differ between glucose tolerance groups. Women with diabetes mellitus had a 4-fold increased risk of a major cognitive decline on the VF test after 4 years compared with nondiabetic women. After multivariate adjustment, VF test scores at follow-up for women were 15.2 +/- 0.6 for those with diabetes, 16.7 +/- 0.4 for those with IGT, and 17.2 +/- 0.2 for those with NGT (P =.007). Glycohemoglobin attenuated this effect, but lipid levels, blood pressure, and microvascular or macrovascular disease did not. Performance on Mini-Mental State Examination and Trail-Making Test B did not differ by baseline glucose status. Elderly white women with diabetes had a more rapid decline in performance on the VF test compared with women with IGT or NGT. Better glucose control might ameliorate this decline.

    The authors evaluated arm and shoulder function and quality of life prospectively after breast reconstruction with the latissimus dorsi flap. Muscle strength was checked by manual muscle test and range of motion preoperatively and then at five postoperative time points: week 2, week 6, month 3, month 6, and month 12. Functional disability and quality of life were also measured by the Disabilities of the Arm, Shoulder and Hand questionnaire and the 36-Item Short-Form Health Survey. The assessments were performed preoperatively and then at three postoperative time-points (i.e., months 3, 6, and 12). Statistical analysis was performed by repeated-measures analysis of variance. Thirty-one patients were included for analysis. All manual muscle test and range-of-motion scale scores at postoperative week 2 decreased significantly compared with preoperative scores. After postoperative month 3, scores for both manual muscle test and range of motion nearly recovered to preoperative status. However, functional disability, according to the Disabilities of the Arm, Shoulder and Hand instrument, was increased considerably after latissimus dorsi flap surgery, and a substantial amount of disability remained 1 year postoperatively. The mental component of the 36-Item Short-Form Health Survey improved consistently for 1 year postoperatively, whereas the physical component decreased significantly until the sixth month postoperatively and was still lower than the preoperative score at postoperative month 12. One year after latissimus dorsi flap surgery, shoulder strength and range of motion returned to baseline. However, functional disability and deteriorated physical aspects of quality of life persisted.

    Objective To determine which gait measures on smooth and uneven surfaces predict falls and fall-related injuries in older subjects with diabetic peripheral neuropathy (DPN). Design Twenty-seven subjects (12 women) with a spectrum of peripheral nerve function ranging from normal to moderately severe DPN walked on smooth and uneven surfaces, with gait parameters determined by optoelectronic kinematic techniques. Falls and injuries were then determined prospectively over the following year. Results Seventeen subjects (62.9%) fell and 12 (44.4%) sustained a fall-related injury. As compared to non-fallers, the subject group reporting any fall, as well as the subject group reporting fall-related injury, demonstrated decreased speed, greater step width (SW), shorter step length (SL) and greater step-width-to-step-length ratio (SW:SL) on both surfaces. Uneven surface SW:SL was the strongest predictor of falls (pseudo-R2 = 0.65; p = .012) and remained so with inclusion of other relevant variables into the model. Post-hoc analysis comparing injured with non-injured fallers showed no difference in any gait parameter. Conclusion SW:SL on an uneven surface is the strongest predictor of falls and injuries in older subjects with a spectrum of peripheral neurologic function. Given the relationship between SW:SL and efficiency, older neuropathic patients at increased fall risk appear to sacrifice efficiency for stability on uneven surfaces. PMID:26053187

    Previous research investigating the relationships between avolition, cognition and functioning in schizophrenia mostly focused on chronic samples and were cross-sectional in design. Impacts of avolition and cognition on longitudinal functional outcome in first-episode patients are under-studied. We assessed 114 Chinese aged 18-55 years presenting with first-episode schizophrenia-spectrum disorder aiming to identify baseline predictors of 1-year functional outcome. Results showed that both avolition and global cognition independently predicted functioning, with avolition being the strongest predictor above and beyond cognition and other symptom dimensions. Our findings indicate the central role of in determining longitudinal functional status in the early illness stage.

    Aim To evaluate symptoms in patients with functional (FNLDO) and primary acquired (PANDO) nasolacrimal duct obstruction, evaluated prospectively before and after successful dacryocystorhinostomy (DCR) surgery. Design A questionnaire delivered by interview, pre‐ and postintervention. Methods Consecutive patients with either FNLDO or PANDO were derived from a tertiary referral clinic and private practice of two surgeons (GW and ICF). The preoperative cohort consisted of 33 FNLDO patients and 28 PANDO patients. Of these, only 31 patients elected to proceed to DCR surgery. There were 12 FLNDO patients and 19 PANDO patients in the postoperative cohorts, all with definitive surgical success. Successful DCR surgery was indicated by positive endoscopic Jones 1 testing. Symptoms in relation to the patient's vision, reading, driving, mood, work and embarrassment were assessed. The severity of these symptoms was also graded. Results Vision and reading in particular were affected in both preoperative cohorts, and patients suffered significantly from embarrassment. Of the postoperative cohorts, the FNLDO cohort had a reduced percentage of patients suffering each symptom type, whereas the PANDO group had a reduction in percentage of patients reporting each symptom in some but not all areas. However, the overall severity was reduced in both groups, and embarrassment was significantly reduced in both groups. Conclusion In both FNLDO and PANDO populations, symptoms bother patients significantly, and successful DCR surgery has a positive effect on the patient's physical and psychological well‐being.

    Patients with motor conversion disorder are frequently seen in neurological departments. Long term prognosis is usually considered to be good, although earlier research has been somewhat unsystematic and mostly retrospective. This study follows a well investigated sample of patients for two to five years and attempts to identify predictors associated with prognosis. Thirty patients with a recent onset of motor conversion disorder were assessed for key psychiatric and demographic variables. They were reassessed two to five years later. Nineteen patients had recovered completely and eight patients had improved, while only three patients were unchanged or worse. Contrary to other follow-up studies none of the patients received a rediagnosis of neurological disease. The presence of a personality disorder, concomitant somatic disease, and low DSM-IV axis V score proved to be associated with poor outcome. The results of this study stresses the need for careful and well-conducted neurological and psychiatric assessments in patients with psychogenic paralyses, bearing in mind the substantial possibility for coinciding illnesses. If this is ensured, it appears that the risk of subsequent neurological rediagnosis is negligible.

    Aim To investigate the relationship between the degree of liver dysfunction, quantified by maximal liver function capacity (LiMAx test) and endothelin-1, TNF-α and IL-6 in septic surgical patients. Methods 28 septic patients (8 female, 20 male, age range 35–80y) were prospectively investigated on a surgical intensive care unit. Liver function, defined by LiMAx test, and measurements of plasma levels of endothelin-1, TNF-α and IL-6 were carried out within the first 24 hours after onset of septic symptoms, followed by day 2, 5 and 10. Patients were divided into 2 groups (group A: LiMAx ≥100 μg/kg/h, moderate liver dysfunction; group B: LiMAx <100 μg/kg/h, severe liver dysfunction) for analysis and investigated regarding the correlation between endothelin-1 and the severity of liver failure, quantified by LiMAx test. Results Group B showed significant higher results for endothelin-1 than patients in group A (P = 0.01, d5; 0.02, d10). For TNF-α, group B revealed higher results than group A, with a significant difference on day 10 (P = 0.005). IL-6 showed a non-significant trend to higher results in group B. The Spearman's rank correlation coefficient revealed a significant correlation between LiMAx and endothelin-1 (-0.434; P <0.001), TNF-α (-0.515; P <0.001) and IL-6 (-0.590; P <0.001). Conclusions Sepsis-related hepatic dysfunction is associated with elevated plasma levels of endothelin-1, TNF-α and IL-6. Low LiMAx results combined with increased endothelin-1 and TNF-α and a favourable correlation between LiMAx and cytokine values support the findings of a crucial role of Endothelin-1 and TNF-α in development of septic liver failure.

    Objective To analyze voice function before and after thyroidectomy for patients with normal preoperative voice using a standardized multidimensional voice assessment protocol. Summary Background Data The natural history of post-thyroidectomy voice disturbances for patients with preserved laryngeal nerve function has not been systematically studied and characterized with the intent of using the data for postoperative voice rehabilitation. Methods During a prospective single-arm study, patients with normal voice underwent functional voice testing using a standardized voice grading scale and a battery of acoustic, aerodynamic, glottographic, and videostroboscopic tests before, 1 week after, and 3 months after thyroidectomy. Differences in observed sample means were evaluated using analysis of covariance or t test; categorical data was analyzed using the Fisher exact or chi-square test. Results Fifty-four patients were enrolled; 50 and 46 were evaluable at 1 week and 3 months, respectively. No patient developed recurrent laryngeal nerve injury; one had superior laryngeal nerve injury. Fifteen (30%) patients reported early subjective voice change and seven (14%) reported late (3-month) subjective voice change. Forty-two (84%) patients had significant objective change in at least one voice parameter. Six (12%) had significant alterations in more than three voice measures, of which four (67%) were symptomatic, whereas 25% with three or fewer objective changes had symptoms. Patients with persistent voice change at 3 months had an increased likelihood of multiple (more than three) early objective changes (43% vs. 7%). Early maximum phonational frequency range and vocal jitter changes from baseline were significantly associated with voice symptoms at 3 months. Conclusions Early vocal symptoms are common following thyroidectomy and persist in 14% of patients. Multiple (more than three) objective voice changes correlate with early and late postoperative symptoms. Alterations

    RNA-interference (RNAi) is a useful tool to assess gene function by knocking down expression of a target gene, and has been used successfully in domestic and laboratory organisms. However, RNAi for functional genomics has not fully extended into ecological model organisms in natural environments. Assessment of gene function in the wild is important, because gene function can be environmentally and context-dependent. Here, we present a case study using RNAi to assess gene function in wild paper wasps Polistes metricus, to test roles for two candidate genes (NADH dehydrogenase and Retinoid and fatty acid binding protein) in the development of reproductive castes. Previous studies showed these genes are upregulated in larvae that become queens compared to workers, but this pattern was reversed in the laboratory, making field-based studies necessary. We orally administered dsRNA to larvae in field colonies and found evidence of a short-term knockdown followed by a compensatory rebound in expression for RfaBp. We also observed the predicted worker-like decrease in lipid stores in NADHdh-dsRNA treated wasps, suggesting a possible role for NADHdh in caste development. We discuss our results in the context of challenges for using RNAi for functional genomics in ecological model organisms in the field.

    The incidence and importance of bone marrow involvement and/or early bone lesions in multiple myeloma (MM) precursor diseases is largely unknown. This study prospectively compared the sensitivity of several imaging modalities in monoclonal gammopathy of undetermined significance (MGUS), smoldering multiple myeloma (SMM) and MM. Thirty patients (10 each with MGUS, SMM and MM) were evaluated with skeletal survey, [18F]FDG-PET/CT, [18F]NaF-PET/CT and morphologic dynamic contrast enhanced (DCE)-MRI. An additional 16 SMM patients had skeletal surveys and FDG-PET/CT. Among MGUS patients, DCE-MRI found only one focal marrow abnormality; other evaluations were negative. Among 26 SMM patients, five (19%) were re-classified as MM based on lytic bone lesions on CT and six had unifocal or diffuse marrow abnormality. Among MM, marrow abnormalities were observed on FDG-PET/CT in 8/10 patients and on DCE-MRI in nine evaluable patients. Abnormal NaF uptake was observed only in MM patients with lytic lesions on CT, providing no additional clinical information.

    The study purpose was to test 1-year prospective associations between English-Spanish bilingualism and executive function in 5th to 6th grade students while controlling for biculturalism. Participants included 182 US Latino students (50 % female). Self-report surveys assessed biculturalism, bilingualism, and executive function (i.e., working memory, organizational skills, inhibitory control, and emotional control, as well as a summary executive function score). General linear model regressions demonstrated that bilingualism significantly predicted the summary executive function score as well as working memory such that bilingual proficiency was positively related to executive function. Results are the first to demonstrate (a) prospective associations between bilingualism to executive function while controlling for the potential third variable of biculturalism, and (b) a principal role for working memory in this relationship. Since executive function is associated with a host of health outcomes, one implication of study findings is that bilingualism may have an indirect protective influence on youth development.

    This study was conducted according to GCP criteria as a prospective randomized cross-over study. The primary goal of the study was to determine clinical findings and patient satisfaction with postoperative treatment. 29 patients with a distal radius fracture that was surgically stabilized from volar and who met the inclusion criteria were enrolled over a 12-month period. Each patient randomly received either a dorsal plaster splint or a vacuum-fit flexible but blocked orthosis applied postoperatively in the operating theatre to achieve postoperative immobilization. After one week all patients were crossed over to the complementary device maintaining the immobilization until end of week 2. After week 2 both groups were allowed to exercise wrist mobility with a physiotherapist, in the orthosis group the device was deblocked, thus allowing limited wrist mobility. After week 4 the devices were removed in both groups. Follow-up exams were performed after postoperative weeks 1, 2, 4 and 12. Results were determined after week 1 and 2 using SF 36 and a personally compiled questionnaire; after weeks 4 and 12 with a clinical check-up, calculation of ROM and the DASH Score. Comparison of the two groups showed a significant difference in ROM for volar flexion after 4 weeks, but no significant differences in DASH Score, duration of disability or x-ray findings. With regard to satisfaction with comfort and hygiene, patients were significantly more satisfied with the dynamic orthosis, and 23 of the 29 patients would prefer the flexible vacuum orthosis in future.

    Theoretical models of addiction suggest that a substance use disorder represents an imbalance between hypersensitive motivational processes and deficient regulatory executive functions. Working-memory (a central executive function) may be a powerful predictor of the course of drug use and drug-related problems. Goal of the current functional magnetic resonance imaging study was to assess the predictive power of working-memory network function for future cannabis use and cannabis-related problem severity in heavy cannabis users. Tensor independent component analysis was used to investigate differences in working-memory network function between 32 heavy cannabis users and 41 nonusing controls during an N-back working-memory task. In addition, associations were examined between working-memory network function and cannabis use and problem severity at baseline and at 6-month follow-up. Behavioral performance and working-memory network function did not significantly differ between heavy cannabis users and controls. However, among heavy cannabis users, individual differences in working-memory network response had an independent effect on change in weekly cannabis use 6 months later (ΔR(2) = 0.11, P = 0.006, f(2) = 0.37) beyond baseline cannabis use (ΔR(2) = 0.41) and a behavioral measure of approach bias (ΔR(2) = 0.18): a stronger network response during the N-back task was related to an increase in weekly cannabis use. These findings imply that heavy cannabis users requiring greater effort to accurately complete an N-back working-memory task have a higher probability of escalating cannabis use. Working-memory network function may be a biomarker for the prediction of course and treatment outcome in cannabis users. Copyright © 2013 Wiley Periodicals, Inc.

    Background There is limited outcome measure support for chiropractic manipulative therapy in the management of ankylosing spondylitis. An improvement in specific indices for both function and disease activity during chiropractic therapy for ankylosing spondylitis has not previously been reported. Objective To measure changes in function and disease activity in a patient with ankylosing spondylitis during a course of chiropractic therapy. The clinical management of ankylosing spondylitis, including chiropractic manipulative therapy and the implications of this case study are discussed. Clinical Features A 34-year-old male with a 10 year diagnosis of ankylosing spondylitis sought chiropractic treatment for spinal pain and stiffness. His advanced radiographic signs included an increased atlantodental interspace and cervical vertebral ankylosis. Intervention and outcome The Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), finger-tip-to-floor distance and chest expansion were assessed during an 18 week course of chiropractic spinal manipulation and mobilization therapy. There was a 90% improvement in the disease activity index and an 85% improvement in the functional index from the pre-treatment baseline, as measured by the BASDAI and BASFI respectively. Spinal flexibility and chest expansion also improved. Conclusion To the authors knowledge this is the first study to incorporate ankylosing spondylitis specific indices, for both disease activity and function, to objectively support the use of chiropractic manipulative therapy in the management of ankylosing spondylitis. More intensive research is suggested. PMID:17549197

    Posterior maxillae are often difficult to treat owing to the sinus antrum. Placing implants in remaining bone regions in the atrophic maxilla, without performing sinus grafting, is a challenge. Immediate function adds to this challenge. The purpose of this study was to suggest and evaluate a simplified treatment concept for the rehabilitation of the atrophic maxilla using tilted implants subjected to immediate/early function. Eighteen patients were included in the study. Sixty implants were placed to support 19 fixed partial or full-arch prostheses. Immediate/early function was applied. The patients were followed for a minimum of 1 year after prosthesis connection. Stability measurements and radiographic evaluation of the change of the marginal bone level were performed. One axial and one tilted implant failed in one patient, giving a cumulative survival rate of 96.7%. No failure of provisional prostheses occurred. The mean marginal bone resorption recorded after 1 year was low (0.82 mm for axial implants and 0.34 mm for tilted implants). The results of the present study suggest that tilted implants placed in immediate function may be a viable treatment approach for the rehabilitation of the atrophied maxilla. Simplified treatment procedures, reduced surgical invasion, shorter treatment time, and reduced costs constitute some of the benefits for the patient and the clinician.

    Several studies have found that shorter stature (height and limb length) in late life is associated with dementia and cognitive impairment. The extent to which childhood environment and early life cognitive function accounts for these associations is not clear. We investigated associations of adult trunk height and leg length with cognitive function in middle age, analysing data from the MRC National Survey of Health and Development: a cohort followed from birth to age 53, 1677 of whom had data on all covariates. The four cognitive tests measured verbal ability, word list memory, verbal fluency and speed/concentration. Early life environmental measures included parental education, poverty, parental divorce, physical health, cognitive ability at age 15, own education and own adult social class. After adjusting for gender, shorter trunk length was associated with lower cognitive function on all four tests and shorter leg length with lower verbal intelligence and word list memory. These associations were only partially attenuated following adjustment for childhood adversity/health but were substantially accounted for by cognitive ability at age 15. Shorter stature was associated with lower cognitive function at age 53, the majority of this association being accounted for by cognitive function at age 15. Reduced cognitive reserve may well account for later associations between anthropometric measures and dementia.

    The association between systolic blood pressure (SBP) and cognitive function is controversial in elderly adults. In addition, few studies focused on the cumulative effect of SBP. We aimed to investigate the association between cumulative SBP exposure and cognitive function among middle-aged and elderly adults.The analysis was based on the Asymptomatic Polyvascular Abnormalities Community (APAC) study. The primary predictor was the cumulative SBP calculated by consecutive SBP values measured through baseline (2006-2007) up to the fourth examination (2012-2013). The cognitive function was estimated by mini-mental state examination (MMSE) in the fourth examination. Linear regression and logistic regression analyses were used to investigate the association between cumulative SBP and cognitive function.Among 2211 participants (41.4% female, aged 40-94 years), 167 (7.55%) were diagnosed with cognitive impairment (MMSE score < 24). Higher cumulative exposure to SBP (per SD increment) was independently associated with poor cognitive performance after controlling for multiple factors (P < 0.001). We observed nondifferential association between men and women. However, higher cumulative SBP in the adults aged ≥60 years had a stronger association with poor cognitive performance compared with that in adults aged 40 to 60 years.Greater exposure to cumulative SBP is associated with worse cognitive performance among middle-aged and elderly adults. This association is similar between men and women, but stronger in elderly adults.

    Affective disorders are highly disabling illnesses constituting a significant burden for the patients, their family and the society. Therefore, it would be very useful to find tools which carefully subtype these conditions and have a strong and reliable predictive power concerning the course of illness and health and social functioning. To date, the role of hopelessness and affective temperaments in the prediction of health and social functioning and the course of affective disorders has not been studied. Thus, the aim of the present study was to assess whether affective temperaments and hopelessness, measured during hospitalization, can be useful in the prediction of global functioning (the severity of the illness and the presence and severity of psychosocial problems) at follow-up in inpatients with major depressive disorder and bipolar disorder (BD). The patients were 96 consecutive patients admitted to the inpatient psychiatric clinic of Sant'Andrea Hospital between January 2009 and December 2010. All patients completed the Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS-A) and the Beck Hopelessness Scale on admission. They were contacted on average 14 months after discharge and were asked to complete a telephone interview based on the Health of the Nation Outcome Scales (HoNOS). Two patients committed suicide before the follow-up assessment. Around 77% of the patients who completed the follow-up assessment were diagnosed as BD, and around 47% reported severe hopelessness. In the multivariate analyses, a factor derived from hopelessness and hyperthymia scores and unemployment, independently predicted severity of the illness and psychosocial functioning at the follow-up. Screening for the affective temperament profile and for hopelessness has importance for designing the treatment and rehabilitation plans of affective disorder patients, as these variables are involved in the course and outcome of affective disorder patients and influence

    It has been proposed that remission should be maintained throughout the course of rheumatoid arthritis (RA); however, the evidence supporting this is limited. Physical function measured by the Health Assessment Questionnaire (HAQ) is a major outcome in RA, and HAQ is shown to be one of the strongest predictors of longterm outcomes. The purpose of this study was to investigate the physical function over a long time in patients with RA who achieved sustained remission (SR) compared with that of patients occasionally achieving remission [non-sustained remission (NSR)]. Patients with RA treated with antitumor necrosis factor and included in the South Swedish Arthritis Treatment Group register were eligible for this study. We identified patients with a Disease Activity Score at 28 joints (DAS28) < 2.6 or Simplified Disease Activity Index (SDAI) ≤ 3.3 at some point and those who achieved SR, i.e., remission during consecutive visits for at least 6 months. The course of functional status was assessed using the HAQ at each visit. Of the 2416 patients, 1177 (48.7%) reached DAS28 remission at some point. SR was achieved by 382 (15.8%) for the DAS28 and 186 (7.7%) for the SDAI criteria. Comparing the SR and NSR groups, HAQ improved during the first 12 months in the DAS28 remission. HAQ continued to improve relatively as long as SR was maintained. A higher proportion of patients in SR reached full physical function. In patients with established RA, physical function measured by the HAQ improves in patients reaching SR compared with patients who only occasionally reach remission. The improvement continues while in remission, which supports that maintaining remission should be a treatment goal.

    Primary objective of this study was to assess the effects of trocar-guided transvaginal mesh surgery (TVM) on cure and prevention rates for incontinence, without concomitant surgery for Stress Urinary Incontinence (SUI). Our secondary objectives were anatomical outcomes, relief of symptoms and effect on quality of life (QoL). This prospective observational study evaluated women who underwent TVM for symptomatic stage >2 Pelvic Organ Prolapse (POP). SUI was evaluated objectively using the cough stress test with prolapse reduced. SUI and urge urinary incontinence (UUI) were subjectively evaluated using ICIQ-SF. Anatomical cure was defined as stage <2 at POP-Q. McNemar chi-square test; paired t-test; Mann-Whitney test. Seventy-two patients reached final evaluation (mean follow-up 72 months). In the 40 pre-op continent patients, 34 (85%) remained continent postoperatively and 6 (15%) showed de novo SUI. Only 1 patient chose to undergo subsequent TVT. The number needed to treat was 6 to prevent 1 women developing de novo objective SUI and 39 to prevent 1 woman having to undergo SUI surgery. In the 32 pre-op incontinent patients, 18 (56.3%) became continent postoperatively. Only 1 patient chose to undergo subsequent TVT. UUI was present in 44 patients pre-operatively and 15 (20.8%) post-operatively (1 de novo). Forty-four patients (61.1%) were continent post-operatively for SUI and UUI. We observed a significant improvement in storage, voiding, post-micturition and prolapse-related symptoms. The anatomical cure rate was 87.5% for the anterior compartment and 90.3%.for the apical segment. The apical recurrence was 8.3% in the patients previously hysterectomised, 18.8% in the patients with uterus preservation and 0% in the patients with concomitant hysterectomy. QoL scores improved in all domains except sleep and personal relationships. We observed mesh exposure in 10 patients (13.9%), in 5 of whom it was associated with a concomitant hysterectomy CONCLUSIONS: TVM showed

    We conducted this study to identify the influences and synergistic effects of smoking status and polymorphisms in hedgehog interacting protein (HHIP) on chronic obstructive pulmonary disease (COPD) and lung function decline. A cohort containing 306 COPD patients and 743 healthy subjects was recruited from 25,000 subjects. All selected subjects had chronic cough for over 2 years or a smoking history above 20 pack-years. After 8 years, all subjects were divided into 2 cohorts according to whether they had quit smoking or not. A follow-up of all patients was completed after another period of 10 years. Three variants in HHIP were genotyped to investigate the impacts of gene susceptibility on the development of COPD and lung function decline. During the follow-up tests, forced expiratory volume in 1 s (FEV1) ratios decreased more significantly in COPD patients than in healthy subjects. For variant rs7654947, FEV1 decreased more significantly in CC and CT subjects than in TT subjects. FEV1 in COPD patients with a CC genotype from smoking cohorts reduced markedly when compared to ex-smoking cohorts (case, 30.75% vs. 35.5%; total, 28% vs. 32%). Our results showed that smoking and HHIP variant rs7654947 were associated with COPD development and lung function decline. Moreover, we found that cigarette smoking and gene susceptibility have cooperative effects on COPD risk and lung function decline.

    Humans handle uncertainty poorly. Prospect theory accounts for this with a value function in which possible losses are overweighted compared to possible gains, and the marginal utility of rewards decreases with size. fMRI studies have explored the neural basis of this value function. A separate body of research claims that prediction errors are calculated by midbrain dopamine neurons. We investigated whether the prospect theoretic effects shown in behavioral and fMRI studies were present in midbrain prediction error coding by using the feedback-related negativity, an ERP component believed to reflect midbrain prediction errors. Participants' stated satisfaction with outcomes followed prospect theory but their feedback-related negativity did not, instead showing no effect of marginal utility and greater sensitivity to potential gains than losses.

    Heart failure with preserved ejection fraction (HFpEF) has become the most prevalent form of heart failure in developed countries. Regrettably, there is no evidence-based effective therapy for HFpEF. We seek to evaluate whether inspiratory muscle training, functional electrical stimulation, or a combination of both can improve exercise capacity as well as left ventricular diastolic function, biomarker profile, quality of life (QoL), and prognosis in patients with HFpEF. A total of 60 stable symptomatic patients with HFpEF (New York Heart Association class II-III/IV) will be randomized (1:1:1:1) to receive a 12-week program of inspiratory muscle training, functional electrical stimulation, a combination of both, or standard care alone. The primary endpoint of the study is change in peak exercise oxygen uptake; secondary endpoints are changes in QoL, echocardiogram parameters, and prognostic biomarkers. As of March 21, 2016, thirty patients have been enrolled. Searching for novel therapies that improve QoL and autonomy in the elderly with HFpEF has become a health care priority. We believe that this study will add important knowledge about the potential utility of 2 simple and feasible physical interventions for the treatment of advanced HFpEF.

    The main purpose of the present study was to test the hypothesis that the depressed lung growth attributable to prenatal exposure to polycyclic aromatic hydrocarbons (PAH) may be modified by the intake of antihistamine medications. Individual prenatal PAH exposure was assessed by personal air monitoring in 176 children who were followed over nine years, in the course of which outdoor residential air monitoring, allergic skin tests for indoor allergens, lung function tests (FVC, FEV(1), FEV(05), and FEF(25-75)) were performed. The analysis with the General Estimated Equation (GEE) showed no association between prenatal PAH exposure and lung function in the group of children who were reported to be antihistamine users. However, in the group of antihistamine non-users all lung function tests except for FEF(25-75) were significantly and inversely associated with prenatal airborne PAH exposure. The results of the study suggest that the intake of antihistamine medications in early childhood may inhibit the negative effect of fetal PAH exposure on lung growth and provides additional indirect evidence for the hypothesis that lung alterations in young children resulting from PAH exposure may be caused by the allergic inflammation within lung.

    Previous studies showed functional improvement in stable patients with schizophrenia treated with risperidone long-acting injection (LAI). We therefore re-investigated functional improvement with risperidone LAI in remitted patients, in comparison with stable patients. The study was conducted in real-life conditions because of the high heterogeneity of the patients' situations. This was a multi-centre, prospective observational cohort study involving adult schizophrenia-spectrum chronic patients who were previously treated with risperidone LAI for 6 months. Remission was evaluated using the consensus criteria proposed by the Remission in Schizophrenia Working Group (RSWG). The primary endpoint was global functioning (assessed with the Global Assessment of Functioning scale, GAF) after one year of treatment. Social functioning was a secondary outcome. The analysis included 1490 patients. Attrition rate was 9.1 % at the end of the study. 27.7 % of patients were in remission after one year of risperidone LAI treatment. The mean GAF rating score (62.5 ± 1.5) was higher than the cut-off previously used to identify patients with satisfactory functioning (60) and significantly higher than the mean GAF score in stable, non-remitted patients (48.3, p < 0.001). Social functioning was also high in remitted patients (21.0 ± 3.6 vs. 17.2 ± 3.7 in non-remitted patients, p < 0.001). The results clearly show that after one year of treatment with risperidone LAI, RSWG-remitted patients have a high level of global functioning, which is significantly higher than in stable, non-remitted patients. Social functioning was also higher in remitted patients as compared with stable, non-remitted patients.

    The analysis carried out earlier in Cracow showed that the high level of SO2 and particulate matter (PM) alone cannot be responsible for an excess of chronic chest symptoms and faster lung function deterioration in the population at large. To check the hypothesis that acid aerosols present in the urban air may cause substantial damage of the lungs, data from a 13-year follow-up survey of chronic chest diseases in Cracow (1968-1981) have been reanalyzed. In the plan of the analysis, three areas of the city with various levels of sulfate and sulfur transformation ratio (STR) in the urban air have been defined. In each of the defined areas, the prevalence of chronic chest symptoms, as well as lung function decline, have been studied. In total, the lung function study group consisted of 1414 persons (584 males and 830 females). Those men who lived in the area with the higher sulfate and STR had lower FEV1 levels by about 151 mL than did the residents of the other areas, and this was equivalent to the effect of smoking. In females, the pattern was generally the same. In men, the FEV1 decline rate (mL/year) over the 13-year period was significantly faster by about 11 mL/year in the areas with higher and intermediate STR, which was again equivalent to the effect of smoking. It was found that the level of SO2 and PM in the urban air correlated with the symptom prevalence in women; however, it had no clear impact on lung function deterioration. PMID:2707189

    The main goal of the study was to test the hypothesis that prenatal and postnatal exposure to polycyclic aromatic hydrocarbons (PAH) is associated with depressed lung function in non-asthmatic children. The study sample comprises 195 non-asthmatic children of non-smoking mothers, among whom the prenatal PAH exposure was assessed by personal air monitoring in pregnancy. At the age of 3, residential air monitoring was carried out to evaluate the residential PAH exposure indoors and outdoors. At the age of 5 to 8, children were given allergic skin tests for indoor allergens; and between 5–9 years lung function testing (FVC, FEV05, FEV1 and FEF25–75) was performed. The effects of prenatal PAH exposure on lung function tests repeated over the follow-up were adjusted in the General Estimated Equation (GEE) model for the relevant covariates. No association between FVC with prenatal PAH exposure was found; however for the FEV1 deficit associated with higher prenatal PAH exposure (above 37ng/m3) amounted to 53 mL (p = 0.050) and the deficit of FEF25–75 reached 164 mL (p=0.013). The corresponding deficits related to postnatal residential indoor PAH level (above 42 ng/m3) were 59 mL of FEV1 (p=0.028) and 140 mL of FEF25–75 (p=0.031). At the higher residential outdoor PAH level (above 90 ng/m3) slightly greater deficit of FEV1 (71mL, p = 0.009) was observed. The results of the study suggest that transplacental exposure to PAH compromises the normal developmental process of respiratory airways and that this effect is compounded by postnatal PAH exposure.

    Diaper dermatitis, a common skin problem in newborn infants, is characterized by poor functioning of the skin barrier. This study aimed to elucidate the relationship between skin barrier function in 4-day-old infants and the occurrence of diaper dermatitis during the first month of life. We recruited healthy Japanese infants born at 35 weeks of gestation or more. We measured indicators of skin barrier function, namely skin pH and transepidermal water loss, in 4-day-old infants on four places on the body. Individual characteristics were recorded from the infants' medical charts. The presence of diaper dermatitis was judged using the diaper rash and erythema scoring scale, which was based on daily recording of the infants' skin condition by their parents. The parents also filled out a questionnaire 1 month after birth regarding stool frequency and certain external factors. The association between diaper dermatitis and skin barrier function was assessed using multiple logistic regression analysis. The analysis included 88 infants. The incidence of diaper dermatitis was 25.0%. After adjusting for stool frequency for 1 month we noted that high pH on the inner arm skin in 4-day-old infants increased the risk of diaper dermatitis during the first month of life (adjusted odds ratio 3.35 [95% confidence interval = 1.12, 10.04]). Early neonatal skin pH may predict the risk of diaper dermatitis during the first month of life. Our results may be useful in devising strategies to prevent diaper dermatitis.

    Studies of brain development suggest that the increase in risk taking observed during adolescence may be due to insufficient prefrontal executive function compared to a more rapidly developing subcortical motivation system. We examined executive function as assessed by working memory ability in a community sample of youth (n = 387, ages 10 to 12 at baseline) in three annual assessments to determine its relation to two forms of impulsivity (sensation seeking and acting without thinking) and a wide range of risk and externalizing behavior. Using structural equation modeling, we tested a model in which differential activation of the dorsal and ventral striatum produces imbalance in the function of these brain regions. For youth high in sensation seeking, both regions were predicted to develop with age. However, for youth high in the tendency to act without thinking, the ventral striatum was expected to dominate. The model predicted that working memory ability would exhibit (1) early weakness in youth high in acting without thinking but (2) growing strength in those high in sensation seeking. In addition, it predicted that (3) acting without thinking would be more strongly related to risk and externalizing behavior than sensation seeking. Finally, it predicted that (4) controlling for acting without thinking, sensation seeking would predict later increases in risky and externalizing behavior. All four of these predictions were confirmed. The results indicate that the rise in sensation seeking that occurs during adolescence is not accompanied by a deficit in executive function and therefore requires different intervention strategies from those for youth whose impulsivity is characterized by early signs of acting without thinking.

    Objectives Multimorbidity, defined as the presence of 2 or more chronic medical conditions in an individual, is associated with poorer health outcomes. Several multimorbidity measures exist, and the challenge is to decide which to use preferentially in predicting health outcomes. The study objective was to compare the performance of 5 count-based multimorbidity measures in predicting emergency hospital admission and functional decline in older community-dwelling adults attending primary care. Setting 15 general practices (GPs) in Ireland. Participants n=862, ≥70 years, community-dwellers followed-up for 2 years (2010–2012). Exposure at baseline: Five multimorbidity measures (disease counts, selected conditions counts, Charlson comorbidity index, RxRisk-V, medication counts) calculated using GP medical record and linked national pharmacy claims data. Primary outcomes (1) Emergency admission and ambulatory care sensitive (ACS) admission (GP medical record) and (2) functional decline (postal questionnaire). Statistical analysis Descriptive statistics and measure discrimination (c-statistic, 95% CIs), adjusted for confounders. Results Median age was 77 years and 53% were women. Prevalent rates ranged from 37% to 91% depending on which measure was used to define multimorbidity. All measures demonstrated poor discrimination for the outcome of emergency admission (c-statistic range: 0.62, 0.65), ACS admission (c-statistic range: 0.63, 0.68) and functional decline (c-statistic range: 0.55, 0.61). Medication-based measures were equivalent to diagnosis-based measures. Conclusions The choice of measure may have a significant impact on prevalent rates. Five multimorbidity measures demonstrated poor discrimination in predicting emergency admission and functional decline, with medication-based measures equivalent to diagnosis-based measures. Consideration of multimorbidity in isolation is insufficient for predicting these outcomes in community settings. PMID:27650770

    Although isokinetic dynamometry often serves as a reference to assess the concurrent validity of weight-machine isotonic strength testing, it is unknown whether isokinetic knee strength is associated with knee function and activity level more strongly than isotonic knee strength in patients with an anterior cruciate ligament reconstruction (ACLR). This study aimed to compare the associations of isokinetic and isotonic knee strength with knee function and work-and-sports activity levels in patients with ACLR. One-hundred and six patients with a unilateral ACLR participated. At three months post-ACLR, isokinetic quadriceps and hamstrings strength was measured using an isokinetic dynamometer whilst isotonic strength was measured using weight machines. At six months post-ACLR, patients performed the single-leg hop-for-distance test. Self reported knee function and work-and-sports activity levels were assessed by the Lysholm Knee Score and Tegner Activity Score, respectively. In multivariable analyses, isotonic and isokinetic quadriceps strength limb symmetry indices (LSIs) were significantly associated with all outcomes (P≤0.03) and had comparable predictive performance. Isotonic and isokinetic hamstrings strength LSIs were significantly associated with Lysholm scores (P≤0.03) and isotonic hamstrings strength was additionally significantly associated with hop-for-distance LSI (P=0.01). Weight machine-derived isotonic quadriceps strength was independently and consistently associated with knee function and work-and-sport activity level post-ACLR. Isokinetic knee strength was not more strongly associated than isotonic knee strength with the various outcomes. These findings have logistic and economic implications because the isokinetic dynamometer system is relatively expensive and its operation requires more logistic effort and technical skills.

    Subjective memory impairment (SMI) may precede mild cognitive impairment (MCI) stage and would offer an earlier therapeutic opportunity than MCI would. However, it is not clear whether complaints of forgetfulness are truly reflective of objective memory dysfunction or of impairments in other cognitive domains. The aim of this current longitudinal study was to investigate changes in various cognitive functions and in regional cerebral metabolic rate of glucose (rCMRglc) among elderly women with SMI. Clinical evaluation, comprehensive neuropsychological test, and (18) F-fluoro-2-deoxyglucose positron emission tomography scans were conducted on 24 women with SMI at the baseline and 24-month follow-up. Changes in the cognitive domain scores and rCMRglc were assessed, and the relationships between them were analyzed. All participants stayed in SMI all the way till the follow-up, not converted to MCI or dementia. A significant reduction in executive function was found (mean difference in z-score: -0.21, P = 0.02) without changes in other cognitive domains. Declines in rCMRglc were detected in the left superior temporal gyrus, right posterior cingulate gyrus, left parahippocampal gyrus, right lingual gyrus, and right angular gyrus. The change in executive function had a positive correlation with the percent change of rCMRglc in the right posterior cingulate gyrus (β = 0.43, P = 0.02). Our findings suggest that elderly women with SMI symptoms should be carefully monitored for declines in executive function and related brain glucose metabolism over time. © 2016 John Wiley & Sons A/S.

    Background Anticoagulation management is difficult in chronic kidney disease, with frequent supratherapeutic international normalized ratio (INR ≥4) increasing hemorrhagic risk. We evaluated whether the interaction of INR and lower estimated glomerular filtration rate (eGFR) increases hemorrhage risk and whether patients with lower eGFR experience slower anticoagulation reversal. Study Design Prospective cohort study. Setting & Participants Warfarin pharmacogenetics cohort (WPC) (1273 long-term warfarin users). Warfarin reversal cohort (WRC) (74 warfarin users admitted with INR ≥4). Predictor eGFR , INR as time-dependent covariate and their interaction in the pharmacogenetics cohort; eGFR in the reversal cohort. Outcomes & Measurements In the pharmacogenetics cohort, hemorrhagic (serious, life-threatening, fatal bleeding) risk was assessed using proportional hazards regression. In the reversal cohort, anticoagulation reversal was assessed from changes in INR, warfarin and metabolite concentrations, clotting factors (II, VII, IX and X), and PIVKA-II (protein induced by vitamin K absence or antagonist II) levels at presentation and after reversal, using linear regression and path analysis. Results In the pharmacogenetics cohort, 454 (35.7%) had eGFR<60 mL/min/1.73 m2. There were 137 hemorrhages in 119 patients over 1802 person-years of follow-up (incidence rate, 7.6 [95% CI, 6.4–8.9]/100 person-years). Patients with lower eGFR had higher frequency of INR ≥4 (p<0.001). Risk of hemorrhage was significantly affected by INR-eGFR interaction. At INR<4 there was no difference in hemorrhage risk by eGFR (all p-values ≥0.4). At INR ≥4, patients with eGFR 30–44 and <30 mL/min/1.73 m2 had 2.2-fold (95% CI, 0.8–6.1; p=0.1) and 5.8-fold (95% CI, 2.9–11.4; p<0.001) higher hemorrhage risk, respectively, versus those with eGFR≥60 mL/min/1.73 m2. In the reversal cohort, 35 (47%) had eGFR<45 mL/min/1.73 m2. Patients with eGFR<45 mL/min/1.73 m2experienced slower

    Background: Since the publication of the Rome III criteria for functional dyspepsia (FD), the evidence about the efficacy of half-dose of proton pump inhibitors for dyspepsia symptoms have been limited. Objective: To examine the efficacy of lansoprazole for functional dyspepsia (FD) diagnosed with the Rome III criteria by the multicentre, double-blind, randomized, placebo-controlled study in Japan. Methods: A total of 54 FD participants were randomized to lansoprazole 15 mg once daily or placebo for a 4-week double-blind treatment period. The primary efficacy endpoint was an overall dyspeptic symptom relief rate evaluated by 5-point Likert scale scores. The alteration of dyspeptic symptom scores during the study period was also assessed. Results: At week 4, the overall dyspeptic symptom relief rates were higher in the lansoprazole group (30.4%) than in the placebo group (6.7%) (p = 0.045). The scores for epigastric pain (p = 0.045) and epigastric burning (p = 0.03) were significantly improved in the lansoprazole group compared to the placebo group, whereas the improvement of the scores for postprandial fullness (p = 0.81) and early satiation (p = 0.33) was not different between lansoprazole and placebo groups. Conclusions: Lansoprazole 15 mg ameliorates dyspeptic symptoms, particularly the epigastric pain syndrome-related symptoms of FD. PMID:24917996

    Status epilepticus (SE) that is resistant to two antiepileptic compounds is defined as refractory status epilepticus (RSE). In the few available retrospective studies, estimated RSE frequency is between 31% and 43% of patients presenting an SE episode; almost all seem to require a coma induction for treatment. We prospectively assessed RSE frequency, clinical predictors, and outcome in a tertiary clinical setting. Over 2 years we collected 128 consecutive SE episodes (118 patients) in adults. Clinical data and their relationship to outcome (mortality and return to baseline clinical conditions) were analyzed. Twenty-nine of 128 SE episodes (22.6%) were refractory to first- and second-line antiepileptic treatments. Severity of consciousness impairment and de novo episodes were independent predictors of RSE. RSE showed a worse outcome than non-RSE (39% vs. 11% for mortality; 21% vs. 63% for return to baseline clinical conditions). Only 12 patients with RSE (41%) required coma induction for treatment. This prospective study identifies clinical factors predicting the onset of SE refractoriness. RSE appears to be less frequent than previously reported in retrospective studies; furthermore, most RSE episodes were treated outside the intensive care unit (ICU). Nonetheless, we confirm that RSE is characterized by high mortality and morbidity.

We evaluated whether the interaction of INR and lower estimated glomerular filtration rate (eGFR) increases hemorrhage risk and whether patients with lower eGFRs experience slower anticoagulation reversal. Prospective cohort study. Warfarin pharmacogenetics cohort (1,273 long-term warfarin users); warfarin reversal cohort (74 warfarin users admitted with INRs ≥ 4). eGFR, INR as time-dependent covariate, and their interaction in the pharmacogenetics cohort; eGFR in the reversal cohort.

    Synthosomes are mechanically stable vesicles with a block copolymer membrane and an engineered transmembrane protein acting as selective gate. The polymer vesicles are nanometer-sized (50-1000 nm) and functionalized by loading them with enzymes for bioconversions or encapsulating charged macromolecules for selective compound recovery/release. The Synthosome system might become a novel technology platform for biocatalysis and selective product recovery. Progress in Synthosome research comprises employed block copolymers, transmembrane channel engineering, and functionalizations, which are discussed here in detail. The challenges in transmembrane protein engineering, as well as cost-effective production, in block copolymer design and the state of the art in Synthosome characterization comprising quantification of encapsulated protein, translocation efficiency, number of transmembrane channels per vesicle, and enzyme kinetics are also presented and discussed. An assessment of the Synthosome technology platform for prospective applications in industrial (white) biotechnology concludes this review.

    This paper describes the rationale and methodology of the PROSPECTS study, a study which aims to assess the course and prognosis of medically unexplained physical symptoms (MUPS), in terms of symptom severity and physical and social functioning. Additionally, it aims to identify different course types and to determine which factors are associated with these course types. Based on these factors, one or more prediction models will be developed. This study is a prospective, multicenter longitudinal cohort study with 1 baseline and 4 follow-up measurements during a 3 year period. 450 MUPS patients (age 18-70 years) will be included, divided over a primary care group, recruited in general practices, and a secondary/tertiary care group, recruited in specialized MUPS care programs. Primary outcome measures are severity of symptoms and degree of functional impairment. Secondary outcome measures are health care consumption and level of depressive symptoms and anxiety. Potential predictors are based on current theoretical models describing the perpetuation of MUPS and include somatic, psychological and social factors. Latent Class Growth Mixture Modeling will be used to identify distinct course types. Logistic regression analysis will be used to identify risk factors associated with these course types. Finally, one or more multivariate prediction models for the course of MUPS will be developed and tested. The PROSPECTS study aims to enhance our insight into the course of MUPS, thus contributing to better recognition of future patients at risk for persistent MUPS. Copyright © 2014 Elsevier Inc.

    To identify sexual function improvement associated with alfuzosin (10 mg daily for 2 years). We enrolled 30 men with lower urinary tract symptom (LUTS) who visited Gyeongsang National University Hospital between 2010 and 2012. At first visit, urinalysis, prostate specific antigen, transrectal ultrasound, and uroflowmetry were performed. The nternational Prostate Symptom Score (IPSS), quality of life (QoL), International Index of Erectile Function (IIEF), and Male Sexual Health Questionnaire Ejaculation Function Domain (MSHQ-EjFD) questionnaires were administered, and the subjects answered the same questionnaires at 1 month, 6 months, 1 year, and 2 years of follow-up. Twelve men completed of the entire study. After administration of alfuzosin, the median IPSS at first visit, 1 month, 6 months, 1 year, and 2 years was 18.00 (interquatile range [IQR]: 14.00~29.75), 20.00 (IQR: 11.50~30.00), 15.50 (IQR: 8.50~25.25), 14.50 (IQR: 9.25~19.50), and 11.50 (IQR: 5.00~17.75), respectively, which showed an improvement. The median QoL at the same times was 4.50 (IQR: 4.00~5.00), 4.50 (IQR: 4.00~5.00), 3.00 (IQR: 2.00~4.00), 3.50 (IQR: 2.25~4.00), and 3.00 (IQR: 1.00~3.00), respectively, and also showed improvement. Likewise, the median IIEF was 36.50 (IQR: 24.50~46.75), 37.50 (IQR: 26.75~47.25), 45.50 (IQR: 35.00~59.75), 48.50 (IQR: 34.75~62.75), and 47.50 (IQR: 43.25~61.00), while the median MSHQ-EjFD was 19.00 (IQR: 12.0~24.75), 19.50 (IQR: 13.50~27.75), 23.00 (IQR: 19.25~32.25), 26.50 (IQR: 18.25~34.50), 27.00 (IQR: 21.50~32.50), respectively, with both showing improvement. After administration of alfuzosin (10 mg daily for 2 years), the IPSS, QoL, IIEF, and MSHQ-EjFD all improved significantly. This means long-term administration of 10 mg of alfuzosin daily would be effective not only for LUTS but also erectile function and ejaculation.

    Purpose: To evaluate late pulmonary function changes after incidental pulmonary irradiation for breast cancer. Methods and Materials: Forty-three consecutive female patients diagnosed with breast carcinoma and treated with postoperative radiation therapy (RT) at the same dose (50 Gy) and fractionation (2 Gy/fraction, 5 days/week) were enrolled. Pulmonary function tests (PFT) and ventilation/perfusion scans were performed before RT and 6, 12, 24, and 84 months afterward. Results: Forty-one patients, mean age 55 years, were eligible for the analysis. No differences were found in the baseline PFT values for age, smoking status and previous chemotherapy; women undergoing mastectomy showed baseline spirometric PFT values lower than did women treated with conservative surgery. The mean pulmonary dose was 10.9 Gy, being higher in women who also received lymph node RT (15.8 vs 8.6, P<.01). Only 1 patient experienced symptomatic pneumonitis. All PFT values showed a reduction at 6 months. From then on, the forced vital capacity and forced expiratory volume in 1 second began their recovery until reaching, and even exceeding, their baseline values at 7 years. Diffusing capacity of the lungs for carbon monoxide and ventilation/perfusion scans continued to reduce for 24 months and then partially recovered their baseline values (-3.5%, -3.8%, and -5.5%, respectively). Only the percentage difference at 7 years in the ventilation scan correlated with the dosimetric parameters studied. Other variables, such as age, smoking status, previous chemotherapy, and concomitant tamoxifen showed no significant relation with changes in PFT ({Delta}PFT) values at 7 years. Conclusions: The study of reproducible subclinical parameters, such as PFT values, shows how their figures decrease in the first 2 years but practically recover their baseline values in the long term. The extent of the reduction in PFT values was small, and there was no clear association with several dosimetric and clinical

    Background: The Functional Movement Screen (FMS) is a tool that is commonly used to predict the occurrence of injury. Previous studies have shown that a score of 14 or less (with a maximum possible score of 21) successfully predicted future injury occurrence in athletes. No studies have looked at the use of the FMS to predict injuries in hockey players. Objective: To see if injury in major junior hockey players can be predicted by a preseason FMS. Methods: A convenience sample of 20 hockey players was scored on the FMS prior to the start of the hockey season. Injuries and number of man-games lost for each injury were documented over the course of the season. Results: The mean FMS score was 14.7+/−2.58. Those with an FMS score of ≤14 were not more likely to sustain an injury as determined by the Fisher’s exact test (one-tailed, P = 0.32). Conclusion: This study did not support the notion that lower FMS scores predict injury in major junior hockey players. PMID:25550667

    Summary Background/objectives Environmental exposure and personal susceptibility both contribute to the development of hand eczema. In this study, we investigated the effect of loss-of-function mutations in the filaggrin gene (FLG), atopic dermatitis and wet work exposure on the development of hand eczema in apprentice nurses. Methods Dutch apprentice nurses were genotyped for the four most common FLG mutations; atopic dermatitis and hand eczema history were assessed by questionnaire. Exposure and hand eczema during traineeships were assessed with diary cards. Results The prevalence of hand eczema during traineeships was higher among subjects with a history of hand eczema reported at inclusion. Hand washing during traineeships and at home increased the risk of hand eczema. After adjustment for the effects of exposure and FLG mutations, an odds ratio of 2.5 (90% confidence interval 1.7–3.7) was found for a history of atopic dermatitis. In this study, an increased risk of hand eczema conferred by FLG mutations could not be shown, but subjects with concomitant FLG mutations and atopic dermatitis showed the highest risk of hand eczema during traineeships. Conclusion A history of atopic dermatitis, a history of hand eczema and wet work exposure were the most important factors increasing the risk of hand eczema during traineeships. PMID:24102300

    We describe a prospective study of histidinaemia. Probands and siblings (n = 21) with typical histidinaemia in 16 families were ascertained by newborn screening; diagnosis was confirmed by appropriate investigations in each subject; none had been treated by low histidine diet. The median age of subjects with histidinaemia was 9.5 y (mean 10.0, SD 3.5, range 6-18). Age-matched sib-pairs and their mothers were studied. IQ scores (Full Scale, Verbal and Performance Scores), Visual-Motor Integration Performance (Bender Gestalt and Koppitz scores), Wide Range Achievement Test (Reading and Mathematics), school performance, and psychological history were evaluated, as well as the medical history (pregnancy, delivery, neonatal, post-natal development). Findings were correlated with biochemical phenotype. CNS development in histidinaemic subjects (mean and distribution of scores) was normal; outlier values did not correlate with degree of histidinaemia. We can conclude that histidinaemia detected by newborn screening is a non-disadaptive phenotype.

    To estimate responsiveness (sensitivity to change) and minimally important difference (MID) for the Patient-Reported Outcomes Measurement Information System (PROMIS) 20-item physical functioning scale (PROMIS PF-20). The PROMIS PF-20, short form 36 (SF-36) physical functioning scale, and Health Assessment Questionnaire (HAQ) were administered at baseline, and 6 and 12 months later to a sample of 451 persons with rheumatoid arthritis. A retrospective change (anchor) item was administered at the 12-month follow-up. We estimated responsiveness between 12 months and baseline, and between 12 months and 6 months using one-way analysis of variance F-statistics. We estimated the MID for the PROMIS PF-20 using prospective change for people reporting getting 'a little better' or 'a little worse' on the anchor item. F-statistics for prospective change on the PROMIS PF-20, SF-36 and HAQ by the anchor item over 12 and 6 months (in parentheses) were 16.64 (14.98), 12.20 (7.92) and 10.36 (12.90), respectively. The MID for the PROMIS PF-20 was 2 points (about 0.20 of an SD). The PROMIS PF-20 is more responsive than two widely used ('legacy') measures. The MID is a small effect size. The measure can be useful for assessing physical functioning in clinical trials and observational studies. Published by the BMJ Publishing Group Limited.

    Pertrochanteric hip fractures occur in an elderly population and cause considerable morbidity and loss of functional ability as the fracture heals. Recently, parathyroid hormone (PTH), which is licensed for the treatment of osteoporosis, has been shown to potentially accelerate bone healing in animal and human studies. If its administration could allow a faster functional recovery after pertrochanteric hip fracture, then a patient's hospital stay may be reduced and rehabilitation could be potentially accelerated. PTH can currently only be administered by subcutaneous injection. The acceptability of this intervention is unknown in this elderly population. The aim of this pilot study is to inform the design of a future powered study comparing the functional recovery after pertrochanteric hip fracture in patients undergoing standard care versus those who undergo administration of subcutaneous injection of PTH. The study is an open label, prospective, randomised, comparative pilot study with blinded outcomes assessment to establish feasibility of the trial design. Patients will be randomised to receive a 6-week course of PTH or usual treatment. Functional outcomes will be assessed at 6 weeks and 12 weeks. Blinded assessment will be used to minimise the effect of bias of an open label study design. A nested qualitative study will investigate the patient experience of, and expectations following, hip fracture and the patient important aspects of recovery compared with the outcome measures proposed. Results will be analysed to establish the potential recruitment, compliance and retention rates using 95% CIs, and trial outcomes quoted with SDs and 95% CIs for the effect size. The study has been approved by the South West 2 Research Ethics committee (reference 10/H0206/34). The findings of this study will be disseminated to the medical community via presentations to orthopaedic, orthogeriatric and osteoporosis societies, and their relevant specialist journals. ISRCTN

    The only known genetic cause of brachytelephalangic chondrodysplasia punctata is X-linked chondrodysplasia punctata 1 (CDPX1), which results from a deficiency of arylsulfatase E (ARSE). Historically, ARSE mutations have been identified in only 50% of male patients, and it was proposed that the remainder might represent phenocopies due to maternal-fetal vitamin K deficiency and maternal autoimmune diseases. To further evaluate causes of brachytelephalangic chondrodysplasia punctata, we established a Collaboration Education and Test Translation program for CDPX1 from 2008 to 2010. Of the 29 male probands identified, 17 had ARSE mutations that included 10 novel missense alleles and one single-codon deletion. To determine pathogenicity of these and additional missense alleles, we transiently expressed them in COS cells and measured arylsulfatase E activity using the artificial substrate, 4-methylumbelliferyl sulfate. In addition, clinical data were collected to investigate maternal effects and genotype-phenotype correlations. In this study, 58% of males had ARSE mutations. All mutant alleles had negligible arylsulfatase E activity. There were no obvious genotype-phenotype correlations. Maternal etiologies were not reported in most patients. CDPX1 is caused by loss of arylsulfatase E activity. Around 40% of male patients with brachytelephalangic chondrodysplasia punctata do not have detectable ARSE mutations or known maternal etiological factors. Improved understanding of arylsulfatase E function is predicted to illuminate other etiologies for brachytelephalangic chondrodysplasia punctata.

    PURPOSE To determine neurocognitive, educational and psychological functioning during childhood and early-adolescence among survivors of early-life meningitis who are apparently healthy. METHODS In the general population-based Avon Longitudinal Study of Parents and Children birth cohort, meningitis exposure was determined at age 18 months. The outcomes of IQ, short-term memory, working memory, reading and spelling abilities, psychological and behavioural problems, depressive and anxiety symptoms, and psychotic experiences at ages 9 to 13 years were compared between those exposed and unexposed to meningitis. Individuals with special educational needs were excluded. RESULTS By age 18 months, 67 out of 11,035 children were reported to have suffered from meningitis (0.61%). These children, compared with the unexposed, performed worse on all neurocognitive and educational measures; mean difference in total IQ 7.36 (95% CI 1.60-13.11). Meningitis was associated with higher depressive and anxiety symptoms (p=0.02), psychological and behavioural problems (p=0.09), and increased risk of psychotic experiences; risk ratio 2.22 (95% CI 1.12-4.38). CONCLUSIONS Exposure to meningitis in the early-life is associated with neurocognitive, educational and psychological difficulties during childhood and early-adolescence among survivors who are apparently healthy. Therefore, focusing only on serious neurologic disabilities may underestimate the true impact of early-life meningitis. PMID:25794764

    To determine neurocognitive, educational, and psychological functioning during childhood and early adolescence among survivors of early life meningitis who are apparently healthy. In the general population-based Avon Longitudinal Study of Parents and Children birth cohort, meningitis exposure was determined at age of 18 months. The outcomes of intelligence quotient, short-term memory, working memory, reading and spelling abilities, psychological and behavioral problems, depressive and anxiety symptoms, and psychotic experiences at ages 9 to 13 years were compared between those exposed and unexposed to meningitis. Individuals with special educational needs were excluded. By age of 18 months, 67 of 11,035 children were reported to have suffered from meningitis (0.61%). These children, compared with the unexposed, performed worse on all neurocognitive and educational measures; mean difference in total intelligence quotient 7.36 (95% confidence interval, 1.60-13.11). Meningitis was associated with higher depressive and anxiety symptoms (P = .02), psychological and behavioral problems (P = .09), and increased risk of psychotic experiences; risk ratio 2.22 (95% confidence interval, 1.12-4.38). Exposure to meningitis in the early life is associated with neurocognitive, educational, and psychological difficulties during childhood and early adolescence among survivors who are apparently healthy. Therefore, focusing only on serious neurologic disabilities may underestimate the true impact of early life meningitis. Copyright © 2015 Elsevier Inc. All rights reserved.

    We investigated a national cohort of children born extremely immature (<26 weeks gestation, EI) regarding the nature, frequency and severity of the behavioural problems related to the executive functions (EF) and concerning learning skills, from the perspectives of parents and teachers. At 11 years of age 86 of 89 survivors of this cohort were studied and compared with an equal number of controls. Behaviours related to EF, and learning skills were assessed by a validated instrument, namely the Five to Fifteen questionnaire sent by mail to parents and teachers. Compared with controls, parents of EI children reported significantly more problems in behaviours related to EF in all areas assessed (Attention, Hyperactivity/Impulsivity, Hypoactivity, Planning/Organizing, and Working Memory). Teachers' ratings showed a similar pattern. EI children also displayed deficient skills in the 4 standard measures of learning skills. Multivariate analysis revealed that prematurity, gender and behavioural composite score was associated with learning skills. Only a relatively small proportion of EI children (10-30%) exhibited clinically significant impairments. Despite a favourable outcome in many school-age children born at the threshold of viability, these are at increased risk of developing behavioural problems related to EF. ©2013 Foundation Acta Paediatrica.

    We assessed the pretreatment health-related quality of life (HRQOL) and functional status of patients with advanced oral and oropharyngeal cancer. Eighty patients were investigated. HRQOL was assessed by EORTC QLQ-C30/QLQ-H&N35 questionnaires. Functional status assessment comprised speech and oral function tests. The results revealed a wide range of HRQOL and functional deficits before treatment. HRQOL appeared to be related to some extent to tumor site (patients with oral tumors reported more pain compared to patients with oropharyngeal tumors) and tumor classification (patients with T3–T4 tumors reported more trouble opening the mouth and felt more ill compared to patients with T2 tumors). Comorbidity appeared to have a major impact. Patients with comorbidity had significantly worse scores on several scales/items on both the EORTC questionnaires. Functional deficits were related to tumor site, classification and comorbidity. Patients with oral cavity tumors (versus oropharyngeal tumors), patients with T3–T4 tumors (versus T2 tumors), and patients with comorbidity (versus without comorbidity) scored significantly worse on several speech and oral function tests. Impaired speech and oral function appeared to be clearly related to global quality of life (QLQ-C30) and self-reported speech (QLQ-H&N35). Many patients with advanced oral and oropharyngeal cancer have compromised HRQOL and functional status before the start of treatment. In addition to tumor site and tumor classification, comorbidity appears to have a major impact on HRQOL and functional status. Knowledge of pretreatment HRQOL and functional status levels is useful for better understanding the impact of treatment on these outcomes over time. PMID:17273840

    Knowledge of spider bites in Central Europe derives mainly from anecdotal case presentations; therefore we aimed to collect cases systematically. From June 2011 to November 2012 we prospectively collected 17 cases of alleged spider bites, and together with two spontaneous notifications later on, our database totaled 19 cases. Among them, eight cases could be verified. The causative species were: Cheiracanthium punctorium (3), Zoropsis spinimana (2), Amaurobius ferox, Tegenaria atrica and Malthonica ferruginea (1 each). Clinical presentation was generally mild, with the exception of Cheiracanthium punctorium, and patients recovered fully without sequelae. In Switzerland, spider bites generally have a benign clinical course, which is characterised by minor effects, with rapid and complete recovery. Since only verified spider bites can be regarded as spider bites, in the case of clinically important arachnidism, the spider should be sent to an expert for identification. Our study may help to diminish spider fear and reassure people who have experienced a bite.

    Background: Functional endoscopic sinus surgery (FESS) is the mainstay of a therapeutic technique for nasal pathologies. This study is to compare the ability of preoperative dexmedetomidine versus clonidine for producing controlled hypotensive anesthesia during FESS in adults in an ambulatory care setting. Materials and Methods: Sixty patients (25-50 years) posted for ambulatory FESS procedures under general anesthesia were randomly divided into Group C and D (n = 33 each) receiving dexmedetomidine 1 μg/kg and clonidine 1.5 μg/kg, respectively; both diluted in 100 ml saline solution 15 min before anesthetic induction. Nasal bleeding and surgeon's satisfaction score; amount and number of patients receiving fentanyl and nitroglycerine for analgesia and deliberate hypotension, duration of hypotension, post anesthesia care unit (PACU) and hospital stay; hemodynamic parameters and side effects were recorded for each patient. Results: Number and dosage of nitroglycerine used was significantly (P = 0.034 and 0.0001 respectively) lower in Group D compared to that in Group C. Similarly, number of patients requiring fentanyl and dosage of same was significantly lower in Group D. But, the duration of controlled hypotension was almost similar in both the groups. Group D patients suffered from significantly less nasal bleeding and surgeon's satisfaction score was also high in this group. Discharge from PACU was significantly earlier in Group D, but hospital discharge timing was quite comparable among two groups. Intraoperative hemodynamics was significantly lower in Group D (P < 0.05) without any appreciable side effects. Conclusion: Dexmedetomidine found to be providing more effectively controlled hypotension and analgesia, and thus, allowing less nasal bleeding as well as more surgeons’ satisfaction score.

This study is to compare the ability of preoperative and intraoperative esmolol versus dexmedetomidine for producing induced hypotension during FESS in adults in a day care setting. Materials and Methods: Sixty patients (20-45 years) posted for FESS under general anesthesia were randomly divided into Group E (n = 30) receiving esmolol, loading dose 1 mg/kg over 1 min followed by 0.5 mg/kg/h infusion during maintenance and Group D (n = 30) receiving dexmedetomidine 1 μg/kg over 15 min before induction of anesthesia followed by 0.5 μg/Kg/h infusion during maintenance, respectively. Nasal bleeding and Surgeon's satisfaction score; amount and number of patients receiving fentanyl and nitroglycerine for analgesia and deliberate hypotension, Postanesthesia Care Unit (PACU) and hospital stay; hemodynamic parameters and side effects were recorded for each patient. Results: Significantly less number and dosage of nitroglycerine was required (P = 0.0032 and 0.0001, respectively) in Group D compared to that in Group E. Again the number and dosage of patients requiring fentanyl were significantly lower in Group D. However, the duration of controlled hypotension was almost similar in both the groups. Group D patients suffered from significantly less nasal bleeding, and surgeon's satisfaction score was also high in this group. Discharge from PACU and hospital were significantly earlier in Group D.

    To evaluate association of clinical remission at month 6 with functional and structural remissions at month 12 during abatacept treatment in patients with rheumatoid arthritis (RA). This 12-month prospective, multicenter cohort study enrolled 168 patients with RA who started abatacept. Outcomes were assessed using composite measures, quality of life indices, and the van der Heijde-modified total Sharp score (mTSS). The logistic regression analysis was applied to identify factors associated with outcomes and their odds ratios (OR) with 95% confidence interval (95% CI). At month 6 and 12, 21.4% and 26.2% of the patients achieved Simplified Disease Activity Index (SDAI) remission (SDAI <3.3), and 40.6% and 41.7% achieved Health Assessment Questionnaire-Disability Index (HAQ-DI <0.5) remission. Among 129 patients whose mTSS progression was evaluated at month 12, 83 (64.3%) achieved structural remission (ΔmTSS ≤0.5 for 12 months). SDAI remission at month 6 was identified as a significant predictor of both functional (OR, 3.732; 95% CI, 1.328-10.489) and structural remissions (OR, 4.301; 95% CI, 1.298-14.243) at month 12 after adjusting for covariates. Aiming for SDAI remission at month 6 is an appropriate strategy to obtain good functional and structural outcomes at month 12.

    Seventeen consecutive patients (mean (SD) 46 (11) years) with untreated hyperthyroidism and anorexia and 29 patients (35 (9) years) with untreated hyperthyroidism without anorexia were studied. The study was conducted at the thyroid clinic of the PUMC Hospital, Beijing, China from March to August 1997. The patients' ages, serum free calcium, liver function and emotional state, specifically the level of anxiety (using the self anxiety scale, Chinese version), were compared before and/or after antithyroid drug treatment in the two groups. This prospective study suggested that the causes of anorexia in untreated hyperthyroidism are complicated. Older age, abnormal liver function, and the level of anxiety are significantly related to anorexia in untreated hyperthyroidism, but hypercalcaemia was not confirmed to be related to anorexia in the study.

    Ion cyclotron emission (ICE) studies emerged in part from the papers by A.B. Mikhailovskii published in the 1970s. Among the discussed subjects were electromagnetic compressional Alfvénic cyclotron instabilities with the linear growth rate √ {n_α /n_e } driven by fusion products, -particles which draw a lot of attention to energetic particle physics. The theory of ICE excited by energetic particles was significantly advanced at the end of the 20th century motivated by first DT experiments on TFTR and subsequent JET experimental studies which we highlight. More recently ICE theory was advanced by detailed theoretical and experimental studies on spherical torus (ST) fusion devices where the instability signals previously indistinguishable in high aspect ratio tokamaks due to high toroidal magnetic field became the subjects of experiments. We discuss further prospects of ICE theory applications for future burning plasma (BP) experiments such as those to be conducted in ITER device in France, where neutron and gamma rays escaping the plasma create extremely challenging conditions fusion alpha particle diagnostics.

    A prospective study was made in 283 patients who attended IMAN's Children's Hospital, with fever the main symptom. A clinical and paraclinical procedure was designed for the study of each patient. 112 patients were eliminated because they did not follow the established criteria. All patients had acute infectious diseases considered trivial; 85% were 3 weeks to 2 years of age. They all had an antibacterial treatment without precise diagnosis. It was considered that on admission the patients showed a normal course in the natural history of the basic disease. The study group included 171 patients 2 months to 13 years of age; 62.5% had fever due to infection, 12.2% to collagenopathies, 7% to neoplasias 5.2% to miscellaneous causes and 12.8% were not diagnosed. The most common infectious causes for prolonged fever were tuberculosis, upper respiratory infections, amoebic liver abscess, typhoid fever and malaria. Careful questioning and clinical examination were enough to enlighten diagnosis in more than 80% of the patients.

    To investigate erectile function and sexuality before/after implantation of the ATOMS device including continence outcome, pain perception and co-morbidities. We collected data from 34 patients (2010-2014) who were provided with an ATOMS implant due to mild or moderate stress urinary incontinence (SUI) after radical prostatectomy (RPE), transurethral resection (TURP) or radiotherapy. Previous failed implants were no contraindication. Sexuality was evaluated with the International Index of Erectile Function (IIEF-5). The Visual Analog Scale (VAS) and Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) were used to analyse pain perception. Results regarding continence, influence of co-morbidities and drug intake were interpreted. IIEF-5 score increased 6 months after ATOMS implantation with a mean difference of 2.18 (Cl: 1.22, 3.14), p < 0,001). Non-sexually active patients had the greatest benefit. However, 50% of patients achieved a mean IIEF-5 of 10.1 and 38% of patients reported a new onset of sexual activity at follow up (mean IIEF-5 score of 12.9). This is in accordance with reduced SUI and absence of persistent pain syndrome. Overall success rate regarding 24h pad-use was 88% (no pad rate 38%). Previous failed implants did not influence results but diabetes, obesity and drug intake (beta-blockers, antidepressants) led to poorer outcomes. Sexuality and erectile function improves significantly 6 months after ATOMS implantation. We postulate that reduced SUI (also during sexual activity) and absence of chronic pain are the improving factors. ATOMS should be offered to men with mild to moderate SUI who are interested in regaining their erectile function and sexual activity.

    Background Rotating savings and credit associations (ROSCAs) involve group financial self-help activities. These voluntary financial cooperative associations—mujin in Japanese—are found in some rural areas of Japan. Cross-sectional evidence suggests that active participation in mujin correlates with rich social capital and better functional capacities among older adults. However, the effect of mujin on subsequent health outcomes is unknown. Methods In 2003, we conducted a baseline interview survey of 583 functionally independent adults randomly selected from Yamanashi Prefecture residents aged 65 years or older. They were followed up until 2011. We used proportional hazards models, and factor analysis of 8 mujin-related questions identified 2 components: the “intensity and attitude” and “financing” aspects of mujin. Results The hazard ratios (HRs) for incident functional disability—identified by using the public long-term care insurance database—per 1-SD increase in factor scores were 0.82 (95% CI: 0.68–0.99) for the intensity and attitude score and 1.21 (1.07–1.38) for financing score. Adjustments for age, sex, marital status, household composition, physical health, education, income, and other factor scores only slightly attenuated these HRs. The results for mortality models were very similar to those for incident functional disability. Conclusions ROSCA-type activities in Japan could have beneficial effects on the health of older adults if used primarily for the purpose of friendship. Mujin for aggressively financial purposes might be somewhat harmful, as such activities might reflect the “dark side” of social capital, ie, overly demanding expectations of group conformity.

    It is now 2 decades since Mayer et al published their Volvo Award-winning paper entitled "Objective assessment of spine function following industrial injury: a prospective study with comparison group and one-year follow-up." Their landmark paper reported that return to work rates of patients that underwent a "functional restoration" treatment program were double that of a comparative group of patients that were denied treatment by their insurers. These results were considered extraordinary and inspired both debate and enthusiasm. Our goal is to review this landmark study, report on its strengths and weaknesses, and review the studies that have attempted to replicate this work in other settings. We also highlight its contribution to our current knowledge about the treatment of back pain and disability. The major weaknesses of the paper of Mayer et al are the possibility of selection bias in the development of their cohort of patients and the lack of a true randomized controlled study design. These factors may have inflated the rates of return to work. Regardless, their reported results were robust, and cannot be easily dismissed. During the last 20 years, this treatment model has received considerable study worldwide, and it is generally agreed that it is superior to standard care for reducing work absence in patients with chronic low back pain. Additionally, the concepts underlying functional restoration have been found to be highly relevant to patients with chronic low back pain, medical providers, and disability systems and continue to gain acceptance and integration into the care of patients throughout the industrialized world.

    Objectives To identify patient characteristics and surgical factors associated with patient-reported outcomes over 5 years following primary total hip replacement (THR). Design Prospective cohort study. Setting Seven hospitals across England and Scotland. Participants 1431 primary hip replacements for osteoarthritis. Main outcome measures The Oxford Hip Score (OHS) was collected preoperatively and each year up to 5 years postoperatively. Repeated measures such as linear regression modelling are used to identify patient and surgical predictors of outcome and describe trends over time. Results The majority of patients demonstrated substantial improvement in pain/function in the first year after surgery—between 1 and 5 years follow-up, there was neither further improvement nor decline. The strongest determinant of attained postoperative OHS was the preoperative OHS—those with worse preoperative pain/function had worse postoperative pain/function. Other predictors with small but significant effects included: femoral component offset—women with an offset of 44 or more had better outcomes; age—compared to those aged 50–60, younger (age <50) and older patients (age >60) had worse outcome, increasing body mass index (BMI), more coexisting diseases and worse Short Form 36 mental health (MH) was related to worse postoperative pain/function. Assessment of change in OHS between preoperative  and postoperative assessments revealed that patients achieved substantial and clinically relevant symptomatic improvement (change), regardless of variation in these patient and surgical factors. Conclusions Patients received substantial benefit from surgery, regardless of their preoperative assessments and surgical characteristics (baseline pain/function, age, BMI, comorbidities, MH and femoral component offset). Further research is needed to identify other factors that can improve our ability to identify patients at risk of poor outcomes from THR surgery. PMID:23457332

    To evaluate the effect of subclinical hypothyroidism (SCH) screening and intervention on pregnancy outcomes and explore the significance of thyroid function during early pregnancy. Pregnant women were recruited from Peking Union Medical College Hospital (screening group for measuring thyroid function and thyroid antibody in early pregnancy) and Haidian Maternal & Child Health Hospital (control group whose serum was stored and measured shortly after delivery) from July 2011 to December 2012. Thyrotropin levels 2.5-10 mIU/L and free T4 levels in normal range were considered SCH. Some of the screening group were treated with levothyroxine and adjusted. The others did not take medicine but kept a regular follow-up visit to doctors after antenatal clinic. The pregnancy outcomes and complications were compared. 1671 women (675 in screening group and 996 in control group) were recruited. 419 (167 from screening group) women was diagnosed as SCH. In screening group, 105 SCH and 4 hypothyroid women received thyroid hormone replacement therapy. The miscarriage and fetal macrosomia risks were lower, and cesarean was higher in screening group than control. Screening and intervention of SCH can significantly reduce the incidence rate of miscarriage.

    To assess the effect of core strengthening exercises on Cobb angle and muscle activity in male college students with functional scoliosis. Static and dynamic back muscle activity were evaluated via surface electromyography (sEMG). A core exercise protocol comprising 18 exercises was performed three times/week for 10 weeks. Patients were randomly allocated to either a home- or community-based exercise programme. Cervical thoracolumbar scans and sEMG were performed after 10 weeks. A total of 87 students underwent cervical thoracolumbar scans. Of these, 53 were abnormal and were randomised between the home-based (n = 25) or community-based (n = 28) groups. After the 10-week exercise programme, Cobb angles were significantly lower and back muscle strength was significantly improved than baseline in both groups, but there were no statistically significant between group differences. A 10-week core strengthening exercise programme decreases Cobb angle and improves back muscle strength in patients with functional scoliosis. © The Author(s) 2016.

    A total of 133 patients with fractures of the second through the fifth metacarpal bones were randomized to receive either a functional brace (the Galveston metacarpal brace) or a dorsal/ulnar plaster cast. Only 42% of the patients in the metacarpal-brace group completed the treatment, in contrast to 81% of the patients in the plaster-cast group. Complications with the brace were due to 60% of the exclusion. No difference according to gender, age, fracture type, hand affected (right/left), or mechanism of injury was observed between the patients who completed the treatment and those who were excluded. Reduction of fractures could not be demonstrated. Reduction of mobility was more frequent in the plaster-cast group, but three months postinjury no reduction of mobility was observed in either group.

    Introduction Depression during or shortly after hospitalization elevated two to three times the risk of mortality or nonfatal cardiac events, significantly increasing the morbidity and mortality of these patients. Objective To assess the impact of revascularization on symptoms of depression in patients with coronary artery disease. Methods A prospective cohort study of 57 patients of both sexes undergoing coronary artery bypass grafting between June 2010 and June 2011. We used the SF-36 to assess quality of life, and the Beck Depression Inventory to detect depressive symptoms, applied preoperatively and six months. Results The prevalence of patients aged 60-69 years was 22 patients (38.60%), 39 men (68.42%), 26 described themselves as mixed race (45.61%), 16 literate (28.07 %) and 30 married (52.63%). The beck depression inventory score demonstrated increased after revascularization: 15 patients mild (26.32%) at time zero to 17 (29.82%) after. And with moderate, seven patients (12.28%) before and 10 (17.54%) after. In the categories of individuals with decreased minimum degree of 32 (56.14%) to 28 (49.12%), and severe of three (5.26%) for two (3.51%) patients. Association was observed between beck depression inventory, gender, age, lifestyle, comorbidities and quality of life. Conclusion There was a high prevalence of elevated beck depression inventory scores, lowest scores of depressive symptoms among men and association between the improvement of quality of life scores and beck depression inventory.

    Background: Africa has very few neurosurgeons. These are almost exclusively in urban centers. Consequently, people in rural areas, most of the African population, have poor or no access to neurosurgical care. We have recently pioneered rural neurosurgery in Nigeria. Objectives: This report details our initial experiences and the profile of neurosurgical admissions in our center. Methods: A prospective observational study of all neurosurgical patients managed at a rural tertiary health institution in Nigeria from December 2010 to May 2012 was done. Simple descriptive data analysis was performed. Results: A total of 249 males (75.2%) and 82 females (24.8%) were managed. The median age was 37 years (range: Day of birth – 94 years). Trauma was the leading cause of presentation with 225 (68.0%) and 35 (10.6%) having sustained head and spinal injuries, respectively. Operative intervention was performed in 54 (16.3%). Twenty-four (7.2%) patients discharged against medical advice, mostly for economic reasons. Most patients (208, 63.4%) had satisfactory outcome while 30 (9.1%) died. Conclusion: Trauma is the leading cause of rural neurosurgical presentations. There is an urgent need to improve access to adequate neurosurgical care in the rural communities. PMID:27695224

    An epidemic of Mesoamerican Nephropathy (MeN) is killing thousands of agricultural workers along the Pacific coast of Central America, but the natural history and aetiology of the disease remain poorly understood. We have recently commenced a community-based longitudinal study to investigate Chronic Kidney Disease (CKD) in Nicaragua. Although logistically challenging, study designs of this type have the potential to provide important insights that other study designs cannot. In this paper we discuss the rationale for conducting this study and summarize the findings of the baseline visit. The baseline visit of the community-based cohort study was conducted in 9 communities in the North Western Nicaragua in October and November 2014. All of the young men, and a random sample of young women (aged 18-30) without a pre-existing diagnosis of CKD were invited to participate. Glomerular filtration rate (eGFR) was estimated with CKD-EPI equation, along with clinical measurements, questionnaires, biological and environmental samples to evaluate participants' exposures to proposed risk factors for MeN. We identified 520 young adults (286 males and 234 females) in the 9 different communities. Of these, 16 males with self-reported CKD and 5 females with diagnoses of either diabetes or hypertension were excluded from the study population. All remaining 270 men and 90 women, selected at random, were then invited to participate in the study; 350 (97%) agreed to participate. At baseline, 29 (11%) men and 1 (1%) woman had an eGFR <90 mL/min/1.73 m(2). Conducting a community based study of this type requires active the involvement of communities and commitment from local leaders. Furthermore, a research team with strong links to the area and broad understanding of the context of the problem being studied is essential. The key findings will arise from follow-up, but it is striking that 5% of males under aged 30 had to be excluded because of pre-existing kidney disease, and that

    The prospective acquisition of reliable patient-reported outcomes (PROs) measures demonstrating the effectiveness of spine surgery, or lack thereof, remains a challenge. The aims of this study are to compare the reliability of functional outcomes metrics obtained using full time employee (FTE) vs. non-FTE-dependent methodologies and to determine the independent predictors of response reliability using non FTE-dependent methodologies. One hundred and nineteen adult patients (male: 65, female: 54) undergoing one- and two-level lumbar fusions at Duke University Medical Center were enrolled in this prospective study. Enrollment criteria included available demographic, clinical and baseline functional outcomes data. All patients were administered two similar sets of baseline questionnaires-(I) phone interviews (FTE-dependent) and (II) hardcopy in clinic (patient self-survey, non-FTE-dependent). All patients had at least a two-week washout period between phone interviews and in-clinic self-surveys to minimize effect of recall. Questionnaires included Oswestry disability index (ODI) and Visual Analog Back and Leg Pain Scale (VAS-BP/LP). Reliability was assessed by the degree to which patient responses to baseline questionnaires differed between both time points. About 26.89% had a history an anxiety disorder and 28.57% reported a history of depression. At least 97.47% of patients had a High School Diploma or GED, with 49.57% attaining a 4-year college degree or post-graduate degree. 29.94% reported full-time employment and 14.28% were on disability. There was a very high correlation between baseline PRO's data captured between FTE-dependent compared to non-FTE-dependent methodologies (r=0.89). In a multivariate logistic regression model, the absence of anxiety and depression, higher levels of education (college or greater) and full-time employment, were independently associated with high response reliability using non-FTE-dependent methodologies. Our study suggests that

    Myocardial extracellular volume (ECV) accumulation is one of the key pathophysiologic features of heart failure with preserved ejection fraction (HFpEF). Our aims were to (1) measure ECV by cardiac magnetic resonance T1 mapping using the modified Look-Locker inversion recovery (MOLLI) sequence, (2) validate MOLLI-ECV against histology, and (3) investigate the relationship between MOLLI-ECV and prognosis in HFpEF. One-hundred seventeen consecutive HFpEF patients underwent cardiac magnetic resonance imaging, coronary angiography, and invasive hemodynamic assessments at baseline. Eighteen patients also underwent left ventricular biopsy for histological analysis (Histo-ECV). To assess the prognostic impact of MOLLI-ECV, its association with hospitalization for heart failure/cardiac death was tested by multivariable Cox regression analysis. Histo-ECV was 30.1±4.6% and was significantly correlated with MOLLI-ECV (R=0.494, P=0.037). Patients were followed for 24.0 months (6.0-32.0 months), during which 34 had a cardiac event. By Kaplan-Meier analysis, patients with MOLLI-ECV ≥ the median (28.9%) had shorter event-free survival (log-rank, P=0.028). MOLLI-ECV significantly correlated with N-terminal prohormone of brain natriuretic peptide (P<0.001), 6-minute walk distance (P=0.004), New York Heart Association functional class (P=0.009), right atrial pressure (P=0.037), and stroke volume (P=0.043). By multivariable Cox regression analysis, MOLLI-ECV was associated with outcome among imaging variables (P=0.038) but not after adjustment for clinical and invasive hemodynamic parameters. We demonstrate that MOLLI-ECV in HFpEF accurately reflects histological ECV, correlates with markers of disease severity, and is associated with outcome among cardiac magnetic resonance parameters but not after adjustment for important clinical and invasive hemodynamic parameters. Nevertheless, MOLLI-ECV has the potential of becoming an important biomarker in HFpEF. © 2016 American Heart

    Great progress has been made in the last 20 years in the study of proton emission from unstable nuclei, but the prospects for additional strides in the next several years are bright. The present main limitations on the study of proton radioactivity are related to the inability to produce copious quantities of nuclides beyond the proton drip line, and the difficulty of measuring proton radioactivity of a mass-separated nucleus in the first few microseconds of its existence. At the Holifield Facility we will attack the second of these limitations by using new signal processing CAMAC modules DGF-4C. Digitizing of the preamplifier signals should enable the analysis of a proton decay occurring at times even less than 1 microsecond after an implant in a strip detector. In the same process, the threshold energy at which we can make measurements will be lowered. These two things will hopefully enable the measurement of lower-energy, but faster decays of isotopes in the 100Sn region and below. For the latter region, the proton decays crucial for a rp-process scenario are of particular interest (e.g. 69Br decay). Secondly, for very short-lived species, we plan to make measurements (without residue separation) at points much closer to the target, thus reducing the flight time between the target and detector. As more intense radioactive beams become available, eg. 56Ni, we will utilize these to produce more neutron-deficient nuclides by use of colder reactions than is possible with stable beams. In some cases where delayed proton emitters are present in the same isobaric chain, the use of the cold reactions with radioactive beams can provide purer samples of the isotope of interest, with a reduction in background from the delayed proton emitters in the same mass chain.

    The purpose of this prospective clinical study was to identify the true incidence, pattern, and location of the injury and nature of fracture after hand injuries in different pediatric age groups attending a hand unit. Three hundred sixty children (237 boys, 123 girls) under 16 years of age who presented with hand injuries between April 1, 2000, and Sept. 30, 2000, were included in the study. Bony injuries accounted for 65.5% (236 injuries); 33.3% (120 injuries) were soft tissue injuries. The projected annual incidence rate for skeletal injuries was 418/100,000 children. The incidence was low in toddlers (34/100,000), more than doubled in preschool children (73/100,000), and steeply increased to around 20-fold after the 10th year (663/100,000). Girls had a higher incidence of hand injuries among toddlers and preschool children. Crushing was the most common cause of hand injury (64%), and most injuries were sustained at home (45%). Toddlers sustained soft tissue injuries predominantly (86%) and older children sustained more bony injuries (77%). Sport was the cause of injures commonly in the older children. There was a higher incidence of fracture in the little finger (52%) followed by the thumb (23%). The proximal phalanx was the most frequently fractured bone (67%) among the phalanges. Diaphyseal fractures (46%) were more common in the metacarpals, and basal fractures (51%) were common in the phalanges. At discharge more than 80% of the patients felt that they were cured or significantly better. This paper highlights the changing pattern and the different varieties of hand injuries in different pediatric age groups.

    Prospective cohorts have played a major role in understanding the contribution of diet, physical activity, medical conditions, and genes to the development of many diseases, but have not been widely used for occupational exposures. Studies in agriculture are an exception. We draw upon our experience using this design to study agricultural workers to identify conditions that might foster use of prospective cohorts to study other occupational settings. Prospective cohort studies are perceived by many as the strongest epidemiologic design. It allows updating of information on exposure and other factors, collection of biologic samples before disease diagnosis for biomarker studies, assessment of effect modification by genes, lifestyle, and other occupational exposures, and evaluation of a wide range of health outcomes. Increased use of prospective cohorts would be beneficial in identifying hazardous exposures in the workplace. Occupational epidemiologists should seek opportunities to initiate prospective cohorts to investigate high priority, occupational exposures. PMID:25603935

    Although tube thoracostomy is a common procedure after thoracic trauma, incomplete evacuation of fluid places the patient at risk for retained hemothorax. As little as 300 to 500 cm of blood may result in the need for an additional thoracostomy tube or, in more severe cases, lung entrapment and empyema. We hypothesized that suction evacuation of the thoracic cavity before tube placement would decrease the incidence of late complications. Patients requiring tube thoracostomy within 96 hours of admission were prospectively identified and underwent suction evacuation of the pleural space (SEPS) before tube placement. These patients were compared to historical controls without suction evacuation. Demographics, admission vital signs, laboratory values, details of chest tube placement, and outcomes were collected on all patients. Multivariable logistic regression was used to compare outcomes between groups. A total of 199 patients were identified, consisting of 100 retrospective controls and 99 SEPS patients. There were no differences in age, sex, admission injury severity score or chest abbreviated injury score, admission laboratory values or vital signs, or hospital length of stay. Mean (SD) volume of hemothorax in SEPS patients was 220 (297) cm; with only 48% having a volume greater than 100 cm at the time of tube placement. Three patients developed empyema, and 19 demonstrated retained blood; there was no difference between SEPS and control patients. Suction evacuation of the pleural space was significantly protective against recurrent pneumothorax after chest tube removal (odds ratio, 0.332; 95% confidence interval, 0.148-0.745). Preemptive suction evacuation of the thoracic cavity did not have a significant impact on subsequent development of retained hemothorax or empyema. Suction evacuation of the pleural space significantly decreased incidence of recurrent pneumothorax after thoracostomy removal. Although the mechanism is unclear, such a benefit may make this

    Approximately 17 % of all fractures involve the distal radius. Two-thirds require reduction due to displacement. High redislocation rates and functional disability remain a significant problem after non-operative treatment, with up to 30 % of patients suffering long-term functional restrictions. Whether operative correction is superior to non-operative treatment with respect to functional outcome has not unequivocally been confirmed. The IlluminOss® System was introduced in 2009 as a novel, patient-specific, and minimally invasive intramedullary fracture fixation. This minimally invasive technique has a much lower risk of iatrogenic soft tissue complications. Because IlluminOss® allows for early mobilization, it may theoretically lead to earlier functional recovery and ADL independence than non-operative immobilization. The main aim of this study is to examine outcome in elderly patients who sustained a unilateral, displaced, extra-articular distal radius fracture that was treated with IlluminOss®. The design of the study will be a multicenter, prospective, observational study (case series). The study population comprises elderly (60 years or older; independent in activities of daily living) with a unilateral, displaced, extra-articular distal radius fracture (AO/OTA type 23-A2 and A3) that after successful closed reduction was fixed within 2 weeks after the injury with IlluminOss®. Critical elements of treatment will be registered, and outcome will be monitored until 1 year after surgery. The Disabilities of the Arm, Shoulder, and Hand score will serve as primary outcome measure. The Patient-Rated Wrist Evaluation score, level of pain, health-related quality of life (Short Form-36 and EuroQoL-5D), time to ADL independence, time to activities/work resumption, range of motion of the wrist, radiological outcome, and complications are secondary outcome measures. Health care consumption and lost productivity will be used for a cost analysis. The cost analysis

    In this study, we aimed to investigate the intrinsic hippocampal functional connectivity (FC) network and its relationship with prospective memory in patients with breast cancer suffering from chemotherapy-induced cognitive impairment (CICI). Thirty-four breast cancer patients before and after adjuvant chemotherapy (CB and CC, respectively) and 31 age- and education-matched cognitively normal (CN) women were recruited and subjected to a prospective memory task and a resting-state functional magnetic resonance imaging scan. Seed-based functional connectivity analysis was used to compare the hippocampal FC networks between CC and CN groups. Partial correction analysis was used to examine the association between the hippocampal FC network and prospective memory in the CC group. The cancer group that underwent chemotherapy obtained significantly poorer scores than the CN group on mini-mental state examination, verbal fluency test, digit span, and prospective memory examination. Compared to the CN group, CC group showed increased hippocampal connectivity in the frontal and parietal cortex, precuneus, posterior cingulate cortex, and the cerebellum. In addition, the increasing hippocampal FC networks were negatively correlated with prospective memory performance in the CC group. These findings suggest maladaptive hippocampal functioning as a mechanism underlying the impairment of prospective memory in patients experiencing CICI. PMID:28327626

With new technologies, epidemiologists can expand their prospective studies to include functional genomics given either as transcriptomics, mRNA and microRNA, or epigenetics in blood or other biological materials. The novel functional analyses should not be assessed using classical survival analyses since the main goal is not risk estimation, but the analysis of functional genomics as part of the dynamic carcinogenic process over time, i.e., a "processual" approach. In the risk factor model, time to event is analysed as a function of exposure variables known at start of follow-up (fixed covariates) or changing over the follow-up period (time-dependent covariates). In the processual model, transcriptomics or epigenetics is considered as functions of time and exposures. The success of this novel approach depends on the development of new statistical methods with the capacity of describing and analysing the time-dependent curves or trajectories for tens of thousands of genes simultaneously. This approach also focuses on multilevel or integrative analyses introducing novel statistical methods in epidemiology. The processual approach as part of systems epidemiology might represent in a near future an alternative to human in vitro studies using human biological material for understanding the mechanisms and pathways involved in carcinogenesis.

    There is extensive evidence of negative consequences of childhood maltreatment for IQ, academic achievement, and posttraumatic stress disorder (PTSD), and increased attention to neurobiological consequences. However, few prospective studies have assessed the long-term effects of abuse and neglect on executive functioning. This study examined whether childhood abuse and neglect predicts components of executive functioning and nonverbal reasoning ability in middle adulthood and whether PTSD moderates this relationship. Using a prospective cohort design, a large sample (N = 792) of court-substantiated cases of childhood physical and sexual abuse and neglect (ages 0-11 years) and matched controls were followed into adulthood (mean age = 41 years). Executive functioning was assessed with the Trail Making Test-Part B and nonverbal reasoning was assessed with the Matrix Reasoning test. PTSD (DSM-III-R lifetime diagnosis) was assessed at age 29 years. Data were analyzed using ordinary least squares regressions, controlling for age, sex, and race, and possible confounds of IQ, depression, and excessive alcohol use. In multivariate analyses, childhood maltreatment overall and childhood neglect predicted poorer executive functioning and nonverbal reasoning at age 41 years, whereas physical and sexual abuse did not. A past history of PTSD did not mediate or moderate these relations. Childhood maltreatment and neglect specifically have a significant long-term impact on important aspects of adult neuropsychological functioning. These findings suggest the need for targeted efforts dedicated to interventions for neglected children. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    Little is known about how clinicians use platelet function testing to guide choice and dosing of adenosine diphosphate receptor inhibitor (ADPri) therapy in routine community practice. The Treatment With Adenosine Diphosphate Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome (ACS)-Prospective, Open Label, Antiplatelet Therapy Study (TRANSLATE-POPS) was a cluster-randomized trial in which 100 hospitals were assigned access to no-cost platelet function testing versus usual care for acute myocardial infarction patients treated with percutaneous coronary intervention. In both arms, ADPri treatment decisions were left up to the care team. The primary end point was the frequency of ADPri therapy adjustment before discharge. Secondary end points included 30-day rates of major adverse cardiovascular events and Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries-defined bleeding events. Platelet function testing was performed in 66.9% of patients treated in intervention sites versus 1.4% of patients in usual care sites. Intervention arm patients were more likely to have ADPri therapy adjustment than usual care patients (14.8% versus 10.5%, P=0.004; odds ratio 1.68, 95% confidence interval 1.18-2.40); however, there were no significant differences in 30-day major adverse cardiovascular events (4.8% versus 5.4%, P=0.73; odds ratio 0.94, 95% confidence interval 0.66-1.34) or bleeding (4.3% versus 4.2%, P=0.33; odds ratio 0.86, 95% confidence interval 0.55-1.34). One-year outcomes were also not significantly different between groups. An as-treated analysis showed higher incidence of ADPri therapy adjustment among intervention arm patients who received platelet function testing than untested usual care arm (16.4% versus 10.2%, P<0.0001), but no significant differences in major adverse cardiovascular events or bleeding.

    2013-01-01

    Background Physical and mental function are strong indicators of disability and mortality. OEF/OIF Veterans returning from deployment have been found to have poorer function than soldiers who have not deployed; however the reasons for this are unknown. Methods A prospective cohort of 790 soldiers was assessed both pre- and immediately after deployment to determine predictors of physical and mental function after war. Results On average, OEF/OIF Veterans showed significant declines in both physical (t=6.65, p<.0001) and mental function (t=7.11, p<.0001). After controlling for pre-deployment function, poorer physical function after deployment was associated with older age, more physical symptoms, blunted systolic blood pressure reactivity and being injured. After controlling for pre-deployment function, poorer mental function after deployment was associated with younger age, lower social desirability, lower social support, greater physical symptoms and greater PTSD symptoms. Conclusions Combat deployment was associated with an immediate decline in both mental and physical function. The relationship of combat deployment to function is complex and influenced by demographic, psychosocial, physiological and experiential factors. Social support and physical symptoms emerged as potentially modifiable factors. PMID:23631419

    Objective The present short-term longitudinal study examined the concurrent and prospective relations among executive functioning (i.e., working memory and cognitive flexibility), coping (primary and secondary control coping), and depressive symptoms in children. Method Participants were 192 children between 9 and 15 years old (mean age = 12.36 years, SD = 1.77) recruited from the community. Youth were individually administered neuropsychological measures of executive functioning and intelligence, and completed self-report measures of executive dysfunction, coping, and depressive symptoms in small groups; the latter two measures were completed again four months later (Time 2). Linear regression analyses were used to examine direct associations among executive functions, coping, and depressive symptoms, and a bootstrapping procedure was used to test indirect effects of executive functioning on depressive symptoms through coping. Results Significant prospective relations were found between working memory measured at Time 1 (T1) and both primary and secondary control coping measured at Time 2 (T2), controlling for T1 coping. T1 cognitive flexibility significantly predicted T2 secondary control coping, controlling for T1 coping. Working memory deficits significantly predicted increases in depressive symptoms four months later, controlling for T1 depressive symptoms. Bootstrap analyses revealed that primary and secondary control coping each partially mediated the relation between working memory and depressive symptoms; secondary control coping partially mediated the relation between cognitive flexibility and depressive symptoms. Conclusion Coping may be one pathway through which deficits in executive functioning contribute to children's symptoms of depression. PMID:25651455

    The purpose of our study was to describe the outcomes of persons with penetrating brain injury resulting from a gunshot wound to the head. It is a prospective study of 442 patients admitted with gunshot wounds to the head over a 7 year period to our University Trauma Center Emergency Department, an urban trauma center and an inpatient rehabilitation hospital with a specialized brain injury unit. Measures and factors described include initial Glasgow Coma Scale score, Revised Trauma Score, the Disability Rating Scale, Functional Independence Measure, levels of cognitive functioning, patient demographics, length of stay, hospital charges, and discharge disposition. Initially 36% of patients expired in or were dead upon arrival to the Emergency Department; 64% of patients survived to be admitted for inpatient care. Of those admitted, 41% expired within the first 48 h of admission. Fifty-two percent of those admitted had severe injuries, 7% moderate injuries, and 42% had mild head injuries. Sixty-two percent of the survivors were discharged from acute care to private residences. The remaining 38% were discharged to programs providing varying levels of care depending upon their level of functioning and care needs. Patients sustaining severe injuries following gunshot wound(s) to the head have high early mortality. Survivors able to participate in an inpatient rehabilitation program have good potential for functional improvement.

    The objective of this study is to test the null hypothesis that an S-shaped surgical incision versus conventional (straight) skin incision in the creation of autogenous radiocephalic arteriovenous fistulas (RCAVFs) have no impact on the primary end-point of primary functional maturation and secondary end points of stenosis and thrombosis. A prospective observational comparative consecutive study with intention-to-treat on individuals undergoing only radiocephalic arteriovenous fistula (RCAVFs) over a period of 12 months was conducted. Variables on patient's demographics, comorbidities, anesthesia type, mean arterial blood pressure, thrill, laterality, cephalic vein and radial artery diameter were collated. The test of probability was assessed through Chi-Square, Kaplan-Meier survival estimator and Log-Rank analysis. Total of n = 83 individuals with median age of 67 years (IQR, 20-89) and male predominance 83% during this period were subjected to RCAVF formation. Total of n = 45 patients in straight skin incision were compared to n = 38 individuals in S-shaped group. Despite equal prevalence of demographics, comorbidities, anesthesia type, mean arterial blood pressure (MAP), thrill, laterality, cephalic vein and radial artery diameter (p > 0.05) higher incidence of juxta-anastomotic stenosis was noted in the straight skin incision group (p = 0.029) in comparative and survival analysis (Log-Rank, p = 0.036). The maturation of the entire cohort was 69% (S-shaped 76% vs. straight group 62%) (p > 0.05). The outcome of this study demonstrates that S-shaped surgical skin incision is associated with a lower incidence of stenosis in comparison to straight incision type in RCAVF formation.

    OBJECTIVE To investigate the relationship between fasting glucose levels, insulin resistance, and cognitive impairment in old age. Diabetes is associated with cognitive impairment in older people. However, the link between elevated fasting glucose levels and insulin resistance in nondiabetic individuals, and the risk of cognitive impairment is unclear. RESEARCH DESIGN AND METHODS We analyzed data from, in total, 8,447 participants in two independent prospective studies: the PROspective Study of Pravastatin in the Elderly at Risk (PROSPER), 5,019 participants, aged 69–84 years, and the Rotterdam Study, 3,428 participants, aged 61–97 years. Fasting glucose levels were assessed at baseline in both studies; fasting insulin levels were assessed in the Rotterdam Study only. Cognitive function was assessed in both studies at baseline and during follow-up. RESULTS Subjects with diabetes had impaired cognitive function at baseline. In contrast, in people without a history of diabetes, there was no clear association between baseline fasting glucose levels and executive function and memory, nor was there a consistent relationship between elevated baseline fasting glucose levels and the rate of cognitive decline in either cohort. Insulin resistance (homeostasis model assessment index) was also unrelated to cognitive function and decline. CONCLUSIONS Elevated fasting glucose levels and insulin resistance are not associated with worse cognitive function in older people without a history of diabetes. These data suggest either that there is a threshold for effects of dysglycemia on cognitive function or that factors other than hyperglycemia contribute to cognitive impairment in individuals with frank diabetes.

    Background Chronic kidney disease (CKD) is one of the most serious public health problems. The increasing prevalence of CKD in developed and developing countries has led to a global epidemic. The hypothesis proposed is that patients undergoing dialysis would experience a marked negative influence on physiological variables of sleep and autonomic nervous system activity, compromising quality of life. Methods/Design A prospective, consecutive, double blind, randomized controlled clinical trial is proposed to address the effect of dialysis on sleep, pulmonary function, respiratory mechanics, upper airway collapsibility, autonomic nervous activity, depression, anxiety, stress and quality of life in patients with CKD. The measurement protocol will include body weight (kg); height (cm); body mass index calculated as weight/height2; circumferences (cm) of the neck, waist, and hip; heart and respiratory rates; blood pressures; Mallampati index; tonsil index; heart rate variability; maximum ventilatory pressures; negative expiratory pressure test, and polysomnography (sleep study), as well as the administration of specific questionnaires addressing sleep apnea, excessive daytime sleepiness, depression, anxiety, stress, and quality of life. Discussion CKD is a major public health problem worldwide, and its incidence has increased in part by the increased life expectancy and increasing number of cases of diabetes mellitus and hypertension. Sleep disorders are common in patients with renal insufficiency. Our hypothesis is that the weather weight gain due to volume overload observed during interdialytic period will influence the degree of collapsibility of the upper airway due to narrowing and predispose to upper airway occlusion during sleep, and to investigate the negative influences of haemodialysis in the physiological variables of sleep, and autonomic nervous system, and respiratory mechanics and thereby compromise the quality of life of patients.

    The right heart often receives less attention during echocardiography. The situation is no different in septic shock. We prospectively investigated the echocardiographic indices of the right heart in septic shock adult patients. Septic shock ICU patients within 24 h of admission were subjected to transthoracic echocardiography (TTE) as per the 2005 guidelines from the American Society of Echocardiography. Eighty-eight septic shock patients (M:F = 52:36) underwent TTE. Thirty-six patients survived. Significant differences in demographic and biochemical (laboratory and metabolic) parameters, severity scores, life-support therapies (vasopressors, ventilation), and length of ICU stay were observed between survivors and non-survivors. Right heart abnormalities of chamber dimension and systolic and diastolic function existed in 79, 25, and 86 % of patients, respectively. Right ventricle subcostal wall thickness (91 %), pulse Doppler myocardial performance index (73 %), and E/E' (63 %) were the predominant abnormalities in chamber dimension, systolic function, and diastolic function of the right heart, respectively. However, the presence of these abnormalities did not signify poor survival in our study. Right heart dimensional and functional abnormalities exist in high proportions in septic shock. However, their predictability of poor outcomes remains questionable.

    Background: Attention-deficit hyperactivity disorder (ADHD) is the most common mental and behavioral disorder in school-aged children. This study evaluated the effect of osmotic-release oral system (OROS) methylphenidate (MPH) on cognitive function and academic performance of Chinese school-aged children with ADHD. Methods: This 12-week, prospective, multicenter, open-label, self-controlled study enrolled 153 Chinese school-aged children with ADHD and 41 non-ADHD children. Children with ADHD were treated with once-daily OROS-MPH (18 mg, 36 mg, or 54 mg). The primary endpoints were Inattention/Overactivity (I/O) with Aggression Conners Behavior Rating Scale (IOWA) and Digit Span Test at week 12 compared with baseline. Secondary endpoints included opposition/defiant (O/D) subscale of IOWA, Clinical Global Impression (CGI), Coding Test, Stroop Color-word Test, Wisconsin Card Sorting Test (WCST), academic performance on teacher-rated school examinations, and safety at week 12 compared with baseline. Both non-ADHD and ADHD children received the same frequency of cognitive operational test to avoid the possible bias caused by training. Results: A total of 128 patients were evaluated with cognitive assessments. The OROS-MPH treatment significantly improved IOWA Conners I/O subscale scores at week 12 (3.8 ± 2.3) versus baseline (10.0 ± 2.4; P < 0.0001). Digit Span Test scores improved significantly (P < 0.0001) with a high remission rate (81.1%) at week 12 versus baseline. A significant (P < 0.0001) improvement was observed in O/D subscale of IOWA, CGI, Coding Test, Stroop Color-word Test, WCST, and academic performance at week 12 versus baseline. Very few practice-related improvements were noticed in the non-ADHD group at week 12 compared with baseline. No serious adverse events and deaths were reported during the study. Conclusions: The OROS-MPH treatment effectively controlled symptoms of ADHD and significantly improved academic performance and cognitive function of

    Internal derangements (ID) of the temporomandibular joint (TMJ) have a multifactorial etiology and are most often treated conservatively by splints, physical therapy and medications. Only in 2-5% of cases are the treatment surgical, either by arthroscopy or arthrotomy. To evaluate improvement of mouth opening, pain relief during function, position of the articular disk and complications following Arthroscopic Lyse and Lavage (ALL). A prospective study of 78 patients (138 TMJs) with TMJ ID, 5 males and 73 females, mean age 29.7 years, treated between January 2010 and April 2013, who were refractory to conservative treatment, had limited mouth opening and pain localized to the TMJ during function, and who were submitted to TMJ ALL and followed for a period of 12 months, with periodic reviews. ALL was effective in 93.6% of cases, with 85.3% experiencing improvement in mouth opening and 91.2% in pain reduction during function, 63% improvement in disk position and a rate of complications of 6.2%. In this study the ALL exhibited a high rate of success with low morbidity in internal derangements of the TMJ.

    Platelet transfusion is increasingly used in patients with traumatic intracranial hemorrhage (ICH) on aspirin therapy to minimize the progression of ICH. We hypothesized (null) that platelet transfusion in this cohort of patients does not improve platelet function. We performed a prospective interventional trail on patients with traumatic ICH on daily high-dose (325 mg) aspirin therapy. All patients received one pack of apheresis platelets. Blood samples were collected before and 1 hour after platelet transfusion. Platelet function was assessed using Verify Now Platelet Function Assay, and a cutoff of greater than 550 aspirin reaction units was used to define functioning platelets (FP). Twenty-eight patients were enrolled in the study. On presentation, 79% (22 of 28) of the patients had nonfunctioning platelets (NFPs), and transfusion of platelets did not improve platelet function as 81% (18 of 22) still had NFP. Of the 22 patients, 4 converted from NFP to FP after transfusion. There was no difference in the progression of ICH (37.5% vs. 30%, p = 0.7) or neurosurgical intervention (12.5% vs. 15%, p = 0.86) between patients with FP and NFP after platelet transfusion. Administration of one pack of apheresis platelet did not improve platelet function. In our study, progression of ICH and the need for neurosurgical intervention were independent of platelet function. Further randomized clinical trials are required to assess both the dose dependence effect and role of platelet transfusion in patients on antiplatelet therapy with traumatic ICH.

    The nephrotoxicity of tobramycin given at a dose of 4·5 mg/kg/day for a period of 12 days to a group of 90 patients with a mean age of 62·9 years was studied. Toxicity was determined on the basis of 3 main criteria (oliguria <400 ml/24 hr, serum creatinine 0·4 mg increase over a minimum basal level of 1·2 mg/100 ml, BUN 5 mg increase over a minimum of 25 mg/100 ml); and 3 minor criteria (proteinuria, microhaematuria and cylindruria). These parameters were determined before treatment at 7, 10, 14, 17, 21, and 30 days afterwards. The age and coexistence of factors such as hypertension, diabetes, anaemia, cardiac insufficiency, shock and dehydration were considered. Nephrotoxicity level ranges from 3·3 to 38·8% depending on the criterion used, and is related to hypertension (P<0·001), age (P<0·005) and association with ampicillin (P<0·005). Nephrotoxicity was reversible spontaneously in 96·7% of the cases and no differences have been observed between patients with moderate renal insufficiency and those with normal renal function on the initiation of treatment.

    Immunosuppression adherence among kidney transplant recipients is essential for graft survival. However, nonadherence is common, jeopardizing graft survival. Besides skipping dosages, little is known about other forms of medication nonadherence and their underlying reasons. This study sought to examine patients' extent of medication adherence over time and reasons for nonadherence. Thirty-nine new kidney transplant recipients were asked to complete a month-long medication-taking diary that included reporting medication nonadherence such as skipped medications, medications taken early or late, taking dosages greater or less than prescribed, and the reason for each occurrence of nonadherence. Of the 20 (51%) patients who completed the diary, 11 (55%) reported at least 1 form of nonadherence. Eleven patients reported taking their immunosuppression at least 1 hour later than the prescribed time, 1 patient reported skipping medication, but no patients reported changing the dosage on their own. Immunosuppression was taken on average 1.5 hours after the prescribed time. Of those patients who took their medications late, there were on average 3.1 occasions of taking it late. The most common reasons for this behavior included health care-related issues, followed by oversleeping, being away from home, work-related barriers, and forgetting. The majority of kidney transplant recipients took medications later than prescribed during 1 month. Future research should determine the clinical impact on graft function of late administration of immunosuppression. Interventions should be designed to better assist kidney recipients with taking medications on time, especially when they are away from home.

    In this study, we review transverse momentum dependent (TMD) parton distribution functions, their application to topical issues in high-energy physics phenomenology, and their theoretical connections with QCD resummation, evolution and factorization theorems. We illustrate the use of TMDs via examples of multi-scale problems in hadronic collisions. These include transverse momentum qT spectra of Higgs and vector bosons for low qT, and azimuthal correlations in the production of multiple jets associated with heavy bosons at large jet masses. We discuss computational tools for TMDs, and present the application of a new tool, TMDLIB, to parton density fits and parameterizations.

    A prospective study of nutritional support during pelvic irradiation was carried out in 32 patients with a primary pelvic malignancy and prior weight loss. Both curative and palliative patients were eligible for the study. Seventeen patients were randomized to receive intravenous hyperalimentation (IVH) and fifteen patients served as controls who were maintained on their regular diet. Patients were stratified by percent body weight loss. Tolerance to therapy was assessed by evaluation of functional status and by using nutritional parameters of body weight change, change in serum protein levels, and response to delayed hypersensitivity skin tests. The curative IVH group tolerated therapy well by both functional and nutritional measurements. All curative IVH patients completed the planned radiation therapy without a treatment break and were fully active following treatment. Patients gained an average of 4.0 kg body weight during irradiation, which was significantly different from the curative control patients. They demonstrated a significant increase in serum transferrin reflecting an improvement in visceral protein. In addition, all showed a positive response to delayed hypersensitivity skin tests at the completion of irradiation. The palliative IVH patients often did poorly because of progression of disease and demonstrated only an elevation of serum transferrin during treatment. The results in the curative IVH group suggest a potential adjunctive role for intravenous hyperalimentation in the malnourished cancer patient undergoing pelvic irradiation. Clearly, further study of nutritional support during pelvic irradiation is needed using curative patients with a single tumor type and significant prior weight loss.

    To qualitatively analyse the evolution of filtering blebs after XEN surgery, by using anterior segment optical coherence tomography (AS-OCT). A prospective study was performed on filtering blebs of 30 eyes with cataracts and glaucoma, surgically operated on using phacoemulsification and XEN45 implantation (PHACO-XEN). AS-OCT was used to analyse bleb morphology and reflectivity at 3, 6, and 12 months after surgery. Functionality was studied considering an intraocular pressure (IOP)≤18mmHg without antihypertensive medication. The IOP enabled the blebs to be classified into non-functional: flat (6.67%) and encapsulated (3.33%); and functional (90%), which were then divide by their morphology into cystic (5/27), diffuse (2/27), and layered (20/27). Cystic types had a mean IOP of 12.8, 12.6, and 14.0mmHg at 3, 6 and 12 months, respectively. In the diffuse type, the mean IOP was 13.0, 11.5 and 13.0mmHg at 3, 6 and 12 months, respectively. In the layers pattern the mean IOP was 14.45, 14.55 and 14.8mmHg at 3, 6 and 12 months respectively. The percentage of blebs with high reflectivity was 48.15%, 62.96%, and 77.78%, at 3, 6 and 12 months, with a mean IOP of 14.23, 14.59, and 15.14mmHg in each time period, respectively. AS-OCT could be a good predictor of bleb functionality in PHACO-XEN surgery. Those with a cystic pattern or low reflectivity seem to have better post-operative success. Nevertheless, more long-term studies are required. Copyright © 2017 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U. All rights reserved.

    tendency to model the organisms for which we have the most validation data (e.g., E. huxleyi and Trichodesmium) even when they may represent only a fraction of the biogeochemical functional group we are trying to represent. When we step back and look at the paleo-oceanographic record, it suggests that oxygen concentrations have played a central role in the evolution and emergence of many of the key functional groups that influence biogeochemical cycles in the present-day ocean. However, more subtle effects are likely to be important over the next century like changes in silicate supply or turbulence that can influence the relative success of diatoms versus dinoflagellates, coccolithophorids and diazotrophs. In general, inferences drawn from the paleo-oceanographic record and theoretical work suggest that global warming will tend to favor the latter because it will give rise to increased stratification. However, decreases in pH and Fe supply could adversely impact coccolithophorids and diazotrophs in the future. It may be necessary to include explicit dynamic representations of nitrogen fixation, denitrification, silicification and calcification in our models if our goal is predicting the oceanic carbon cycle in the future, because these processes appear to play a very significant role in the carbon cycle of the present-day ocean and they are sensitive to climate change. Observations and models suggest that it may also be necessary to include the DMS cycle to predict future climate, though the effects are still highly uncertain. We have learned a tremendous amount about the distributions and biogeochemical impact of bacteria in the ocean in recent years, yet this improved understanding has not yet been incorporated into many of our models. All of these considerations lead us toward the development of increasingly complex models. However, recent quantitative model intercomparison studies suggest that continuing to add complexity and more functional groups to our ecosystem

    In this study, we review transverse momentum dependent (TMD) parton distribution functions, their application to topical issues in high-energy physics phenomenology, and their theoretical connections with QCD resummation, evolution and factorization theorems. We illustrate the use of TMDs via examples of multi-scale problems in hadronic collisions. These include transverse momentum qT spectra of Higgs and vector bosons for low qT, and azimuthal correlations in the production of multiple jets associated with heavy bosons at large jet masses. We discuss computational tools for TMDs, and present the application of a new tool, TMDLIB, to parton density fits and parameterizations.

    In a prospective study, 20 patients who underwent harvesting of chin grafts as outpatients, were followed up for 12 months (3 further patients with incomplete follow-up data were excluded from the study). Preoperatively and 7 days, 1, 3, 6 and 12 months postoperatively, follow-up data were assessed. Evaluation of the superficial sensory function of the inferior alveolar nerve was determined by the Pointed-Blunt Test and the Two-Point-Discrimination Test. Sensory disturbances were objectively assessed by testing thermal sensitivity with the "Pain and Thermal Sensitivity" Test (PATH Test). In addition, evaluation of the pulp sensitivity of teeth 35-45 was carried out by cold vitality testing. One week postoperatively, 8 patients were affected by superficial sensory impairment. 8 nerve territories showed hypoaesthetic reactions and 5 showed hyperaesthetic reactions. After 12 months, two patients still suffered from hypoaesthesia of one side of the chin. There was a statistically significant sensitivity impairment of the chin for all patients comparing the preoperative data of the Two-Point-Discrimination Test (left/right median: 8.17/8.17 mm, interquartile range (IQR) 1.00/2.00 mm) with the first postoperative measurement (left/right median 9.00/8.33 mm, IQR 1.67/2.66 mm). Comparing the latter to the last postoperative measurement there was significant tendency for regeneration of a nerve function (left/right median 8.00/7.84 mm, IQR 0.66/2.00 mm). In the PATH Test all hypoaesthetic areas could be identified by a reduction of thermal sensitivity. After the first postoperative examination 21.6% (n=38/176) of the examined teeth had lost their pulp sensitivity. After 12 postoperative months 11.4% (n=20/176) still did not react sensitively. Many of these were canines (n=8/20). Comparing the preoperative to the first postoperative examination, there was a significant reduction of pulp sensitivity. However, statistically significant recovery until the last postoperative

    Transcatheter aortic valve implantation (TAVI) is occasionally associated with stroke and silent cerebral ischemia, which may affect cognitive and functional performance. The aim of this study was to evaluate the changes in cognitive performance and functional status following TAVI. We performed a comprehensive prospective functional, cognitive and quality of life (QOL) evaluation in consecutive patients who underwent TAVI using the CoreValve device (Medtronic Inc.). The evaluation was performed at baseline and 1 month after the procedure and included the 36-item Short-Form Health Survey for QOL assessment, Mini-Mental State Examination (MMSE), quantitative clock drawing test (Rouleau), color trails test, Cognistat evaluation, Barthel Index and Duke Activity Status Index. A total of 36 patients completed the full pre- and post-TAVI evaluation. Mean age was 82.2 ± 4.2 years (52.8% men); 94.5% of patients had low functional class (New York Heart Association III/IV), and 13.9% had prior stroke. After the procedure, all patients had improved functional status and valve hemodynamics. At 1 month, there was a significant improvement in the MMSE and Cognistat evaluations (from 25.9 ± 3.3 to 27.6 ± 2.4, p < 0.001, and from 5 ± 1 to 5.7 ± 0.7, p = 0.001, respectively). Our preliminary results of a comprehensive assessment of patients undergoing TAVI indicate favorable results for both functional performance and cognitive function early after the procedure.

    Acute alcohol intoxication selectively impairs executive functioning and prospective memory (PM). Much previous researches in this area have used laboratory‐based tasks that may not mimic functions that individuals with dysexecutive syndrome have problems with in their everyday life. The present study aimed to assess the effects of a modest dose of alcohol on executive functioning and PM using a virtual reality task and investigate the role of executive planning in PM performance. Forty healthy participants were administered 0.4 g/kg alcohol or matched placebo in a double‐blind design. Executive function and PM were assessed using the Jansari-Agnew-Akesson-Murphy (JAAM) task, requiring participants to play the role of an office worker. Alcohol intoxication selectively impaired executive function and PM. The participants in the alcohol condition performed worse on the planning, prioritisation, creativity and adaptability executive subscales and also on the time‐based and event‐based PM tasks. However, alcohol did not impair the selection executive function task or the action‐based PM task. The results provide further support for the effects of alcohol on executive functioning and PM. In addition, the results suggest that such deficits may be present at relatively modest doses of alcohol and in the absence of a subjective feeling of intoxication.

    Individuals with schizophrenia demonstrate impairment in prospective memory (ProM), which describes the multifaceted ability to execute a future intention. Despite its clear implications for everyday functioning, the neuropsychological substrates and functional correlates of ProM impairment in schizophrenia remain poorly understood. In this study, the Memory for Intentions Screening Test (MIST), a standardized measure of ProM, was administered to 72 outpatients with schizophrenia or schizoaffective disorder as part of a comprehensive neuropsychological and psychiatric research evaluation. Results showed that ProM was positively correlated with standard clinical tests of attention, working memory, processing speed, learning, and executive functioning, but not delayed recall. In the context of multiple neuropsychological predictors, learning ability was the only domain that independently contributed to ProM. Importantly, better ProM was predictive of higher functional capacity (as measured by the UCSD Performance-Based Skills Assessment-Brief Version), above and beyond the variability explained by demographic and disease factors. Analysis of component processes revealed that event-based ProM, as well as no response (i.e., omission) and task substitution errors were the strongest predictors of everyday functioning. Overall, these findings suggest that ProM impairment in schizophrenia is associated with multiple cognitive substrates, particularly episodic learning deficits, and plays an important role in everyday living skills. Studies regarding the potential effectiveness of ProM-based remediation strategies to improve functional outcomes in schizophrenia are indicated.

    Background This article presents an overview of the concept of social capital, reviews prospective multilevel analytic studies of the association between social capital and health, and discusses intervention strategies that enhance social capital. Methods We conducted a systematic search of published peer-reviewed literature on the PubMed database and categorized studies according to health outcome. Results We identified 13 articles that satisfied the inclusion criteria for the review. In general, both individual social capital and area/workplace social capital had positive effects on health outcomes, regardless of study design, setting, follow-up period, or type of health outcome. Prospective studies that used a multilevel approach were mainly conducted in Western countries. Although we identified some cross-sectional multilevel studies that were conducted in Asian countries, including Japan, no prospective studies have been conducted in Asia. Conclusions Prospective evidence from multilevel analytic studies of the effect of social capital on health is very limited at present. If epidemiologic findings on the association between social capital and health are to be put to practical use, we must gather additional evidence and explore the feasibility of interventions that build social capital as a means of promoting health.

    A better alignment in the goals of the biomedical research enterprise and the health care delivery system can help fill the large gaps in our knowledge of the impact of clinical interventions on patient outcomes in the real world. There are several initiatives underway to align the research priorities of patients, providers, researchers, and policy makers. These include Agency for Healthcare Research and Quality (AHRQ)-supported projects to build flexible prospective clinical electronic data infrastructure that meet the needs of these diverse users. AHRQ has previously supported the creation of 2 distributed research networks as a new approach to conduct comparative effectiveness research (CER) while protecting a patient's confidential information and the proprietary needs of a clinical organization. It has applied its experience in building these networks in directing the American Recovery and Reinvestment Act funds for CER to support new clinical electronic infrastructure projects that can be used for several purposes including CER, quality improvement, clinical decision support, and disease surveillance. In addition, AHRQ has funded a new Electronic Data Methods forum to advance the methods in clinical informatics, research analytics, and governance by actively engaging investigators from the American Recovery and Reinvestment Act-funded projects and external stakeholders.

    The Yugoslavia Prospective Study of environmental lead exposure has studied the associations between exposure to lead and pregnancy outcomes; childhood neuropsychological, behavioral, and physical development; and hematologic, renal, and cardiovascular function. The cohort comprises 577 children born to women recruited at midpregnancy in two towns in Kosovo, Yugoslavia; one town is the site of a lead smelter, refinery, and battery plant and the other is 25 miles away and relatively unexposed. A sample of these children has been followed at 6-month intervals through 7.5 years of age. Blood lead concentrations ranged from 1 to 70 microg/dl. Exposure to lead was not associated with adverse pregnancy outcomes. Exposure was associated with modest decrements in intelligence, small increases in blood pressure, higher risks of proteinuria, small increases in behavior problems, and perturbed hematopoiesis. Only at low level exposures (i.e., <16 microg/dl) were small associations with decreased height found. We discuss methodological problems that may hinder causal interpretation of these data, namely, use of blood lead concentration as an exposure measure, confounding, and town-specific associations. We conclude that while reported associations are small, collectively they lend support to the notion that lead is a toxicant with numerous adverse health effects. Images Figure 1 PMID:9872712

    We carried out a prospective study of teleconsulting in orthopaedics. A commercial videoconferencing system was connected by three ISDN lines between the Satakunta Central Hospital in Pori and the Orton Orthopaedic Hospital in Helsinki, 240 km away. A document camera was used to transfer radiographic images and paper documents. Twenty-nine patients who needed an orthopaedic consultation were studied over three months. They were examined by a surgeon in Pori with the aid of teleconferencing and again later in a traditional, face-to-face appointment in Helsinki. Patients and doctors completed questionnaires after the consultations. Technically, the videoconferencing system functioned reliably and the quality of the video was judged to be good. Twenty patients (69%) would not have needed to travel for a face-to-face appointment, because the teleconsultation afforded a definite treatment decision. The orthopaedic surgeons considered all the treatment decisions arising from the teleconsultation good, except in one case which was considered satisfactory. The quality of the radiographic images transferred with the document camera was good or very good in 17 cases and satisfactory in three cases. None of the patients had experienced videoconferencing before; 87% of them thought that teleconsultation was a good or very good method and the rest felt that it was satisfactory. All patients wanted to participate in teleconsultations again and most would have recommended it to other patients.

    To examine the state of, and change in, biopsycho-social health and quality of life of patients after whiplash injury, before and after an inpatient interdisciplinary pain management programme. Observational, prospective cohort study (n = 103) using medical record data and standardized self-assessments to compare health state with general population norms and to determine effects by means of standardized effect sizes. The therapy programme consisted of drug adaptation, graded activity exercise, relaxation therapies, and behavioural therapy. Compared with population norms, patients' health was significantly deteriorated in all dimensions of the Short Form 36, depression and anxiety at all examined times. After rehabilitation, pain improved by effect sizes up to 0.65, function/role performance up to 0.87, vitality up to 0.67 and coping up to 0.41. At the 6-month follow-up, these effects remained, with effect sizes between 0.45 and 0.87. The median working capacity improved from 8 h per w
