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

This study set out to determine whether healthy lifestyle attitudes are different for students in different years of the chiropractic education process. The results of the FANTASTIC Lifestyle Assessment Questionnaire administered to chiropractic students enrolled in first, second and fourth years of study are presented. Significant differences in scores attained were found between the three years of study in question. A minimum sample size (N) of 81 students was used. First year subjects were significantly different from both second year and fourth year subjects’ scores (p = .012 and p < 0.001, respectively). Mean scores decreased with every year of study. The variables ‘year of study’ and ‘age’ had the most pronounced effect on outcome of scores (p < 0.001 and p < 0.001, respectively). Analyses of variance were performed to determine effect of the variables involved. A two-tailed paired t-test was used to check first year students for changes after six months of school. It is still undetermined whether the significant difference in scores between each year of study are due to the year of study, to increasing average age of the classes, or to societal attitudes about wellness. Suggestions for future study are also presented.

This randomized prospective study examines durability of improvement in general symptomatology, psychosocial functioning and interpersonal problems, and compares the long-term efficacy of analytic and systemic group psychotherapy in women 1 year after completion of treatment for childhood sexual abuse. Women (n = 106) randomly assigned to analytic or systemic psychotherapy completed the Symptom Checklist-90-R, Global Assessment of Functioning, Global Life Quality, Registration Chart Questionnaire, and Flashback Registration at pre-treatment, post-treatment, and at a 1-year follow-up. Post-treatment gains were significant for both treatment modalities on all measures, but significantly larger after systemic therapy. Significant treatment response was maintained 1-year post-treatment, but different trajectories were observed: 1 year after treatment completion, improvements for analytic therapy were maintained, whereas they decreased after systemic therapy, resulting in no statistically significant difference in gains between the groups at the 1-year follow-up. Despite maintaining significant gains, more than half of the patients remained above cut-off for caseness concerning general symptomatology at post-treatment and at 1-year follow-up. The findings stress the importance of long-term follow-up data in effect studies. Different trajectories were associated with the two treatments, but improvement in the two treatment groups did not differ significantly at the 1-year follow-up. Implications of the difference in trajectories for treatment planning are discussed. Both analytic and systemic group therapy proved efficient in improving general symptomatology, psychosocial functioning, and interpersonal problems in women with a history of CSA and gains were maintained at a 1-year follow-up. Despite maintaining statistically significant gains at the 1-year follow-up, 54% of the patients remained above the cut-off for caseness with respect to general symptomatology, which may indicate a need for further treatment. Different pre-post follow-up treatment trajectories were observed between the two treatment modalities. Thus, while systemic group therapy showed a significantly better outcome immediately after termination, gains in the systemic treatment group decreased during follow-up, while gains were maintained during follow-up in analytic group therapy. © 2013 The British Psychological Society.
Effects of life history variation on size and growth in stream-dwelling Atlantic salmon

A large size variation amongst life histories for stream-dwelling Atlantic salmon Salmo salar was found and the relative effect of life histories on size varied over time. As early as December (age 0+ years), fish that later smolted at age 2+ years were significantly larger than fish that did not smolt at age 2+ years. In contrast, there were no mass differences at age 0+ years between fish that would mature or not at age 1+ years (October). The mass differences between smolts and non-smolts persisted until smolting, and differences between mature and immature fish first appeared in May (age 1+ years). Following September (age 1+ years), there was also a significant interaction between smolting and maturity. Previously mature and immature age 2+ year smolts were not significantly different in size, but immature age 2+ year non-smolts were much lighter than mature age 2+ year non-smolts. Based on mass differences, the apparent 'decision' to smolt occurred c. 5 months before (winter, age 0+ years) the decision to mature (late spring, age 1+ years). In addition to strong seasonal growth variation, sizes of freshwater Atlantic salmon were largely structured by the complex interaction between smolt-age and maturity. ?? 2003 The fisheries Society of the British Isles.

Assessment of the influence of gender and increasing years at university on sleep health of students. Four hundred and eighteen students from different streams across years of undergraduate to postgraduate courses participated. Descriptive statistics, test of differences, and correlation were used. The sleep health data comprised of subjective evaluation using a questionnaire and personal interviews. Overall, 43.1% had sleep problems, females were more affected (51.67% vs. 48.33% in males) but were early bed goers. The prevalence of circadian rhythm sleep disorder (11.6% vs. 9.5%) and delayed sleep phase syndrome (4.5% vs. 2.7%) was slightly higher in males. The daytime dysfunction and hypnotic use significantly differed in students of the same class among gender. Bedtime got significantly delayed along years [H(2)=29.769, p<0.001], and hypnotic use [H(2)=8.807, p=0.012] differed significantly among them. The moderate-very strong correlational statistics among sleep health elements was very similar across gender and years of university education. However, more pronounced influence of years of university education than gender was seen in the significant differences for correlated correlation among sleep health parameters. Gender and years of university education influence sleep among university students both separately and concomitantly.

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

The aim of this study was to investigate if there were differences in the two-point discrimination (2-PD) of fingers among students at different stages of a chiropractic program. This study measured 2-PD thresholds for the dominant and nondominant index finger and dominant and nondominant forearm in groups of students in a 4-year chiropractic program at the International Medical University in Kuala Lumpur, Malaysia. Measurements were made using digital calipers mounted on a modified weighing scale. Group comparisons were made among students for each year of the program (years 1, 2, 3, and 4). Analysis of the 2-PD threshold for differences among the year groups was performed with analysis of variance. The mean 2-PD threshold of the index finger was higher in the students who were in the higher year groups. Dominant-hand mean values for year 1 were 2.93 ± 0.04 mm and 1.69 ± 0.02 mm in year 4. There were significant differences at finger sites (P < .05) among all year groups compared with year 1. There were no significant differences measured at the dominant forearm between any year groups (P = .08). The nondominant fingers of the year groups 1, 2, and 4 showed better 2-PD compared with the dominant finger. There was a significant difference (P = .005) between the nondominant (1.93 ± 1.15) and dominant (2.27 ± 1.14) fingers when all groups were combined (n = 104). The results of this study demonstrated that the finger 2-PD of the chiropractic students later in the program was more precise than that of students in the earlier program. Copyright © 2017.

To evaluate the effects of different interventions on 12-year-old children's permanent teeth caries and filling rates in Shanghai Jiading District. Six hundred and ninety-one 12-year-old children from 3 middle schools were randomly divided into 3 groups. The filling intervention group received filling of the permanent teeth free of charge for 3 years; The health education group received oral health education for 3 years; The control group only accepted oral examination for 3 years. The data was analyzed with SPSS 20.0 software package for X2 test. On the baseline, the permanent teeth caries rates of 3 groups were 32.10%, 35.56% and 36.84%, and the filling rates were 17.07%, 16.24% and 17.04%, respectively. After 1 year, permanent teeth caries rates of 3 groups were 35.92%, 42.26% and 44.50%, respectively. There was no significant difference among the 3 groups (P>0.05). The filling rates were 93.28%, 61.41%, and 16.67%, respectively. There was significant difference among the 3 groups (P<0.05). After 3 years, permanent teeth caries rates of 3 groups were 37.04%, 48.12% and 58.85%, and the filling rates were 93.66%, 61.51% and 17.28%, respectively. There were significant differences among the 3 groups (P<0.05). Filling intervention and health education can significantly reduce the permanent teeth caries prevalence rate and improve permanent teeth caries filling rate of 12-year-old children. Furthermore, the effects of filling intervention were more significant than the health education intervention.

The aim of this study was cerebrospinal flow quantification in the cerebral aqueduct using cine phase-contrast magnetic resonance imaging (MRI) technique in both sexes and five different age groups to provide normative data. Sixty subjects with no cerebral pathology were included in this study. Subjects were divided into five age groups: < or =14 years, 15-24 years, 25-34 years, 35-44 years, and > or =45 years. Phase, rephase, and magnitude images were acquired by 1.5 T MR unit at the level of cerebral aqueduct with spoiled gradient echo through-plane, which is a cine phase-contrast sequence. At this level, peak flow velocity (cm/s), average flow rate (cm/ s), average flow (L/min), volumes in cranial and caudal directions (mL), and net volumes (mL) were studied. There was a statistically significant difference in peak flow between the age group of < or =14 years and the older age groups. There were no statistically significant differences in average velocity, cranial and caudal volume, net volume, and average flow parameters among different age groups. Statistically significant differences were not detected in flow parameters between sexes. When using cine-phase contrast MRI in the cerebral aqueduct, only the peak velocity showed a statistically significant difference between age groups; it was higher in subjects aged < or =14 years than those in older age groups. When performing age-dependent clinical studies including adolescents, this should be taken into consideration.

To explore the stability of insect resistance during the development of transgenic insect-resistant trees, this study investigated how insect resistance changes as transgenic trees age. We selected 19 transgenic insect-resistant triploid Populus tomentosa lines as plant material. The presence of exogenous genes and Cry1Ac protein expression were verified using polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA) analyses. The toxicity for Clostera anachoreta and Lymantria dispar was evaluated by feeding fresh leaves to first instar larvae after the trees were planted in the field for 2 years and after the sixth year. Results of PCR showed that the exogenous genes had a long-term presence in the poplar genome. ELISA analyses showed significant differences existed on the 6-year-old transgenic lines. The insect-feeding experiment demonstrated significant differences in the mortality rates of C. anachoreta and L. dispar among different transgenic lines. The average corrected mortality rates of C. anachoreta and L. dispar ranged from 5.6-98.7% to 35.4-7.2% respectively. The larval mortality rates differed significantly between the lines at different ages. Up to 52.6% of 1-year-old transgenic lines and 42.1% of 2-year-old transgenic lines caused C. anachoreta larval mortality rates to exceed 80%, whereas only 26.3% of the 6-year-old transgenic lines. The mortality rates of L. dispar exhibited the same trend: 89.5% of 1-year-old transgenic lines and 84.2% of 2-year-old transgenic lines caused L. dispar larval mortality rates to exceed 80%; this number decreased to 63.2% for the 6-year-old plants. The proportion of 6-year-old trees with over 80% larval mortality rates was clearly lower than that of the younger trees. The death distribution of C. anachoreta in different developmental stages also showed the larvae that fed on the leaves of 1-year-old trees were killed mostly during L 1 and L 2 stages, whereas the proportion of larvae that died in L 3 and L 4 stages was significantly increased when fed on leaves of 6-year-old trees. Results of correlation analysis showed there was a significant correlation between the larvae mortality rates of trees at different ages, as well as between Cry1Ac protein contents and larvae mortality rates of 6-year-old trees.

Objectives The objectives of this study were to examine racial differences in reported napping and nighttime sleep of 2- to 8-year-old children, to identify factors accounting for these differences, and to determine if variability in napping was related to psychosocial functioning. Methods Caretakers of 1043 children (73.5% non-Hispanic white; 50.4% male) 2 to 8 years old from a community sample reported on their children’s napping behavior and nighttime sleep. Caretakers of 255 preschool children (3–5 years old) also completed the Behavior Assessment System for Children. Results A more gradual age-related decline in napping was found for black children. At age 8, 39.1% of black children were reported to nap, compared with only 4.9% of white children. Black children also napped significantly more days per week, had shorter average nocturnal sleep durations, and slept significantly less on weekdays than on weekend nights. Despite differences in sleep distribution, total weekly sleep duration (diurnal and nocturnal) was nearly identical for the 2 racial groups at each year of age. Logistic regression analysis revealed that demographic variables were related to but did not fully explain napping differences. Napping in a subset of preschoolers was not significantly related to psychosocial functioning. Conclusions There are remarkable racial differences in reported napping and nighttime sleep patterns beginning as early as age 3 and extending to at least 8 years of age. These differences are independent of commonly investigated demographic factors. Differences in napping behavior do not seem to have psychosocial significance in a sample of preschool children.

To compare the impact of 2 different teaching and learning methods on student mastery of learning objectives in a pharmacotherapy module in the large classroom setting. Two teaching and learning methods were implemented and compared in a required pharmacotherapy module for 2 years. The first year, multiple interactive mini-cases with inclass individual assessment and an abbreviated lecture were used to teach osteoarthritis; a traditional lecture with 1 inclass case discussion was used to teach gout. In the second year, the same topics were used but the methods were flipped. Student performance on pre/post individual readiness assessment tests (iRATs), case questions, and subsequent examinations were compared each year by the teaching and learning method and then between years by topic for each method. Students also voluntarily completed a 20-item evaluation of the teaching and learning methods. Postpresentation iRATs were significantly higher than prepresentation iRATs for each topic each year with the interactive mini-cases; there was no significant difference in iRATs before and after traditional lecture. For osteoarthritis, postpresentation iRATs after interactive mini-cases in year 1 were significantly higher than postpresentation iRATs after traditional lecture in year 2; the difference in iRATs for gout per learning method was not significant. The difference between examination performance for osteoarthritis and gout was not significant when the teaching and learning methods were compared. On the student evaluations, 2 items were significant both years when answers were compared by teaching and learning method. Each year, students ranked their class participation higher with interactive cases than with traditional lecture, but both years they reported enjoying the traditional lecture format more. Multiple interactive mini-cases with an abbreviated lecture improved immediate mastery of learning objectives compared to a traditional lecture format, regardless of therapeutic topic, but did not improve student performance on subsequent examinations.

Objective To investigate the expressions of serum soluble human leukocyte antigen G (sHLA-G) and soluble CD30 (sCD30) in renal transplant recipients at different time after transplantation, and explore the relationship between the expressions of serum sHLA-G, sCD30 and the time after renal transplantation. Methods Eleven kidney transplant recipients and 10 healthy donors were selected, in which the dynamic changes of serum sHLA-G and sCD30 were detected by ELISA before transplantation and 1 year after transplantation; 33 kidney transplant recipients with normal renal graft were selected and divided into three groups: 1-5 years, 5-10 years and 10 years post-transplantation. The expressions of serum sHLA-G and sCD30 in the recipients were tested over one year after transplantation. Results The level of serum sHLA-G before transplantation was not significantly different from that of the control group. There was no significant difference between pre-transplantation, 1 week and 1 month after transplantation. Serum sHLA-G level of renal transplant recipients at 3 months after transplantation was higher than that 1 month after transplantation. There was no significant change in serum sHLA-G level among 3, 6 and 12 months after transplantation. The level of serum sHLA-G in the group of transplant time >10 years was significantly higher than that in the group of transplant time ≤5 years. The serum sHLA-G level was significantly associated with the time after renal transplantation. The level of serum sCD30 before transplantation was higher than that in the control group and decreased in 1 week after transplantation. There were no significant differences in sCD30 level between 1, 3, 6, and 12 months after transplantation, and similarly, there were also no significant differences between the groups of transplant time ≤5 years, 5-10 years and 10 years after transplantation. The level of sCD30 was significantly associated with the time within 1 month after renal transplantation. Conclusion The serum sHLA-G in kidney transplant recipients with normal renal graft increased with the time after renal transplantation, while the serum sCD30 level was reduced within 1 month after renal transplantation.

The aim of this study was to assess the relation between the diagnosis of encopresis at 8 and 10 years of age, and mental and somatic health 10 years later. The importance of type of encopresis (primary or secondary) at 8 years was also studied. Subjects were a non-clinical encopretic sample (N=73) and control subjects (N=75) [2]. Seven assessment variables from conscription surveys provided information about mental and somatic health status at 18 years of age. Former encopretics (n=66) did not differ significantly from the controls (n=67) at 18 years of age, although there were consistent, small negative differences. The boys who at 10 years of age had still been encopretic did not differ significantly at 18 years of age from the boys who at 10 years had recovered from encopresis, and the signs indicating the small differences varied. For former primary and secondary encopretic boys, there were two significant differences, the men in the secondary group being more often exempted from conscription than the primary group and the control cases. The results indicate that boys with non-clinical encopresis show only small, if any, mental and somatic disturbances at the beginning of adulthood. Comprehensive investigations of encopretic patients are recommended as important clinical problems, in addition to encopresis, might be present.

Data from the Victoria Longitudinal Study were used to examine the 6-year longitudinal stability of personality in older adults. Personality was measured with the NEO Personality Inventory. The longitudinal sample consisted of 223 adults initially ranging from 55 to 85 years of age. Longitudinal confirmatory factor analyses were used to examine the stability of individual differences in change over time, and the stability of the longitudinal factor structure. The results indicated both substantial stability at the level of individual differences in change, as well as significant individual differences in change that were related to age and gender. Finally, the factor structure of personality was invariant over time but did not approximate simple structure for the five dimensions of personality. Our study of 6-year personality development provided both (a). a confirmation of early significant stability findings and (b). unique evidence for significant individual differences in late adulthood.

Whether first-year radiology residents are ready to start call after 6 or 12 months has been a subject of much debate. The purpose of this study was to establish an assessment that would evaluate the call readiness of first-year radiology residents and identify any individual areas of weakness using a comprehensive computerized format. Secondarily, we evaluated for any significant differences in performance before and after the change in precall training requirement from 6 to 12 months. A list of >140 potential emergency radiology cases was given to first-year radiology residents at the beginning of the academic year. Over 4 years, three separate versions of a computerized examination were constructed using hyperlinked PowerPoint presentations and given to both first-year and second-year residents. No resident took the same version of the exam twice. Exam score and number of cases failed were assessed. Individual areas of weakness were identified and remediated with the residents. Statistical analysis was used to evaluate exam score and the number of cases failed, considering resident year and the three versions of the exam. Over 4 years, 17 of 19 (89%) first-year radiology residents passed the exam on first attempt. The two who failed were remediated and passed a different version of the exam 6 weeks later. Using the oral board scoring system, first-year radiology residents scored an average of 70.7 with 13 cases failed, compared to 71.1 with eight cases failed for second-year residents who scored statistically significantly higher. No significant difference was found in first-year radiology resident scoring before and after the 12-month training requirement prior to call. An emergency radiology examination was established to aid in the assessment of first-year radiology residents' competency prior to starting call, which has become a permanent part of the first-year curriculum. Over 4 years, all first-year residents were ultimately judged ready to start call. Of the variables assessed, only resident year showed a significant difference in scoring parameters. In particular, length of training prior to taking call showed no significant difference. Areas of weakness were identified for further study. Copyright © 2012 AUR. Published by Elsevier Inc.

This study aims to characterize longitudinal blood pressure (BP) trajectories from childhood in black-white and sex groups and examine the association between childhood level-independent trajectories of BP and adult hypertension. The longitudinal cohort consisted of 2732 adults who had body mass index and BP measured 4 to 15 times from childhood (4-19 years) to adulthood (20-51 years). Model-estimated levels and linear slopes of BP and body mass index at childhood age points were calculated at 1-year intervals using the growth curve parameters and their first derivatives, respectively. Linear and nonlinear curve parameters differed significantly between race-sex groups; BP levels showed race and sex differences 15 years of age onward. Hypertensives had higher long-term BP levels than normotensives in race-sex groups. Although linear and nonlinear slope parameters of BP were race and sex specific, they differed consistently, significantly between hypertension and normotension groups. BP trajectories during young adulthood (20-35 years) were significantly greater in hypertensives than in normotensives; however, the trajectories during middle-aged adulthood (36-51 years) were significantly smaller in hypertensives than in normotensives. Level-independent linear slopes of systolic BP showed significantly negative associations (odds ratio=0.50≈0.76; P <0.001) during prepuberty period (4-11 years) but significantly positive associations (odd ratio=1.44≈2.80, P <0.001) during the puberty period (13-19 years) with adult hypertension, adjusting for covariates. These associations were consistent across race-sex groups. These observations indicate that adult hypertension originates in childhood, with different longitudinal BP trajectory profiles during young and middle-aged adulthood in black-white and sex groups. Puberty is a crucial period for the development of hypertension in later life. © 2017 American Heart Association, Inc.
[Assemblage effect of ground arthropod community in desert steppe shrubs with different ages].

Taking the 6-, 15-, 24- and 36-year-old Caragana intermedia shrubs in desert steppe as a subject, an investigation on soil properties and ground arthropod community was carried out under the shrub and in the open to probe into the assemblage effect of ground arthropod community in desert steppe shrubs with different ages. The results were as follows: 1) In the 6-year-old shrubland, significant differences were only found in soil physical properties (soil texture, soil moisture and electrical conductivity) between the microhabitats under shrub and in the open. Beginning from the 15-year-old shrubland, however, soil organic matter and nutrition (N, P) increased significantly. 2) A total of 27 groups were captured in the studied sites which dominated by Carabidae, Tenebrionidae and Formicidae. From 6- to 15-year-old shrubland, the number of dominant groups decreased while that of common groups increased for the ground arthropod community under the shrub. From 15- to 24- and 36-year-old shrubland, the difference between the microhabitats under the shrub and in the open decreased firstly, and then increased. Some special groups appeared under the shrub in the 36-year-old shrubland, and dung beetles became dominant. 3) In the 6- and 24-year-old shrublands, there were no significant differences in group richness, abundance, and diversity index between the microhabitats under the shrub and in the open. As for the 15- and 36-year-old shrublands, however, significant differences were observed. 4) The shrub age had a stronger effect on the distribution of ground arthropods living under the shrubs compared to that in the open. The changes in soil texture, pH and electrical conductivity could significantly influence on the distribution of ground arthropods under the shrub, also in the open to some degree. It was suggested that the development of shrubland had strong impact on assemblage effect of ground arthropods, which was closely correlated with the stand age and would affect the recovery of sandy grassland ecosystems.
Seasonality and synchrony of reproduction in three species of nectarivorous Philippines bats.

Differences among species and among years in reproductive seasonality (the tendency for clusters of events to fall at approximately the same point in each year) and synchrony (amount of clustering of events within a year) have been intensively studied in bats, but are difficult to assess. Here, we use randomization methods with circular statistics to test for synchrony and seasonality of reproduction in three species of nectarivorous megachiropteran bats on Negros Island in the central Philippines. In Rousettus amplexicaudatus, estimated dates of birth were both highly synchronous and highly seasonal. In Macroglossus minimus, estimated births were seasonal and significantly clustered within years, but within each year births occurred over a broad period, indicating a low level of synchrony. In Eonycteris spelaea, estimated births were also seasonal and had statistically significant synchrony, with birth periods within years intermediate in synchrony between R. amplexicaudatus and M. minimus. All three species had a similar seasonal pattern, with two birth periods in each year, centered on March or April and August or September. In one species, R. amplexicaudatus, primigravid females (in their first pregnancy) produced their young in June and July, a birth period significantly different in timing from the two birth periods of older adult females. This more conservative pattern of young females may allow higher survival of parents and offspring at cost of a lost reproductive opportunity. There was weak evidence that in some years primigravid females of M. minimus might differ in timing from older adults. There were few significant differences in reproductive timing among different years, and those differences were generally less than two weeks, even during a severe drought in the severe el Niño of 1983. The results suggest that these species follow an obligately seasonal pattern of reproductive timing with very little phenotypic plasticity. The resampling methods were sensitive to differences in timing of under two weeks, in some cases, suggesting that these are useful methods for analyses of seasonality in wild populations of bats.

To compare the difference of corresponding age at cervical vertebral maturation (CVM) stages among different skeletal malocclusions and provide clinic guideline on optimal treatment timing for skeletal malocclusion. Based on ANB angle, 2 575 cephalograms collected from Department of Orthodontics, Peking University School and Hospital of Stomatology from May, 2006 to November, 2014 were classified into skeletal Class I (ANB 0°~5°, 1 317 subjects), Class II (ANB > 5°, 685 subjects) and Class III (ANB < 0°, 573 subjects) groups. CVM stages were evaluated with the modified version of CVM method. Independent sample t test was performed to analyze the difference of age at different CVM stages among various skeletal groups. Significant gender difference of age was found at CS3 to CS6 for skeletal Class I group (P < 0.05), at CS5 and CS6 for skeletal Class II group (P < 0.05), and at CS3 and CS5 for skeletal Class III group (P < 0.05). At CS3 stage, the average age of male in skeletal Class II and skeletal Class III groups was (11.6 ± 1.5) years old and (10.3 ± 1.9) years old, respectively; the average age of females in those two groups was (11.7 ± 1.3) years old and (9.3 ± 1.5) years old, respectively, and significant difference was found in both comparisons (P < 0.05). Compared average age at CS5 and CS6 between skeletal Class II and skeletal Class III groups [the ages of male was (15.1 ± 1.7) and (16.8 ± 1.6) years old, the ages of male was (14.6 ± 1.2) and (15.7 ± 2.5) years old], significant difference was also found (P < 0.05). Significant gender differences were found when evaluated CVM stage and age in skeletal Class I, II and III groups. Significant differences of age at different CVM stage was noted when skeletal Class II was compared with skeletal Class III groups.

Current understanding of tumor biology suggests that breast cancer is a group of diseases with different intrinsic molecular subtypes. Anatomic staging system alone is insufficient to provide future outcome information. The American Joint Committee on Cancer (AJCC) expert panel updated the 8th edition of the staging manual with prognostic stage groups by incorporating biomarkers into the anatomic stage groups. In this study, we retrospectively analyzed the data from our center in China using the anatomic and prognostic staging system based on the AJCC 8th edition staging manual. We reviewed the data from January 2008 to December 2014 for cases with Luminal B Human Epidermal Growth Factor Receptor 2 (HER2)-negative breast cancer in our center. All cases were restaged using the AJCC 8th edition anatomic and prognostic staging system. The Kaplan-Meier method and log-rank test were used to compare the survival differences between different subgroups. SPSS software version 19.0 (IBM Corp., Armonk, NY, USA) was used for the statistical analyses. This study consisted of 796 patients with Luminal B HER-negative breast cancer. The 5-year disease-free survival (DFS) of 769 Stage I-III patients was 89.7%, and the 5-year overall survival (OS) of all 796 patients was 91.7%. Both 5-year DFS and 5-year OS were significantly different in the different anatomic and prognostic stage groups. There were 372 cases (46.7%) assigned to a different group. The prognostic Stage II and III patients restaged from anatomic Stage III had significant differences in 5-year DFS (χ2 = 11.319, P= 0.001) and 5-year OS (χ2 = 5.225, P= 0.022). In addition, cases restaged as prognostic Stage I, II, or III from the anatomic Stage II group had statistically significant differences in 5-year DFS (χ2 = 6.510, P= 0.039) but no significant differences in 5-year OS (χ2 = 5.087, P= 0.079). However, the restaged prognostic Stage I and II cases from anatomic Stage I had no statistically significant differences in either 5-year DFS (χ2 = 0.440, P= 0.507) or 5-year OS (χ2 = 1.530, P= 0.216). The prognostic staging system proposed in the AJCC 8th edition refines the anatomic stage group in Luminal B HER2-negative breast cancer and will lead to a more personalized approach to breast cancer treatment.

The purpose of this study was to determine if changes in dental development are associated with Attention Deficit Hyperactivity Disorder (ADHD) or ADHD medications. This retrospective chart review evaluated the dental age of 128 patients between 6 and 16 years of age using the Demirjian method from the following two groups a) children with ADHD b) unaffected children. The ADHD group was further stratified into four groups according to the medication type. The impact of ADHD on dental age difference (the difference between dental age and chronologic age) was analyzed using T-test and the association between medication type and dental age difference was analyzed through one way ANOVA. The mean difference between estimated dental age and chronologic age (dental age difference) for all subjects was 0.80 years. There was no significant dental age difference in subjects with ADHD and the control group (0.78±1.28vs. 0.84 ±1.09 years respectively; P=0.75) and there was no significant difference in dental age difference and type of medication (P=0.84). No significant difference was found between children with ADHD and unaffected children with respect to dental age difference. No significant differences were found in dental age difference in the four medication groups.

The aim of this study was to investigate the relevance of sex, age, and cleft type to velopharyngeal function after primary Sommerlad palatoplasty so as to improve velopharyngeal function after the procedure. Records of 503 patients with nonsyndromic cleft palate after primary Sommerlad palatoplasty were included in the retrospective study. Relevance between their velopharyngeal function and sex, age, and cleft type was analyzed. Statistical analysis was performed using SPSS 13.0 (SPSS Inc., Chicago, IL). There were no significant differences of velopharyngeal competence (VPC) rates between different sexes (P = 0.635). Specifically, VPC rates were significantly higher in younger-than-2-years groups than in older age groups (P < 0.05) and significantly lower in 6-years-or-older group (P < 0.05). No differences were found among 2- to 6-year-old groups (P > 0.05). The VPC rates were significantly lower in the bilateral complete cleft palate and the unilateral complete cleft palate than in the incomplete cleft palate before 2 years old (P < 0.05), whereas there were no significant differences totally (P = 0.875). Results showed that the disparity of the VPC rate among different cleft types would decrease with age. Moreover, results of multivariate logistic regression also indicated that operation age and cleft type are factors influencing velopharyngeal function. Primary palatoplasty should be completed before 2 years old, and the postoperative velopharygeal function will greatly decreases after 6 years old. The influence of cleft type on velopharyngeal function is limited to young patients. For those who have missed the best surgical timing, appropriate delay of operation age is reasonable, especially for patients with complete cleft palate. For patients 4 to 6 years old, the first choice is still simple palatoplasty no matter which cleft type they are classified into.

To evaluate the effects of the parent-reported medical home status on health care utilization, expenditures, and quality for children. Medical Expenditure Panel Survey (MEPS) during 2004-2012, including a total of 9,153 children who were followed up for 2 years in the survey. We took a causal difference-in-differences approach using inverse probability weighting and doubly robust estimators to study how changes in medical home status over a 2-year period affected children's health care outcomes. Our analysis adjusted for children's sociodemographic, health, and insurance statuses. We conducted sensitivity analyses using alternative statistical methods, different approaches to outliers and missing data, and accounting for possible common-method biases. Compared with children whose parents reported having medical homes in both years 1 and 2, those who had medical homes in year 1 but lost them in year 2 had significantly lower parent-reported ratings of health care quality and higher utilization of emergency care. Compared with children whose parents reported having no medical homes in both years, those who did not have medical homes in year 1 but gained them in year 2 had significantly higher ratings of health care quality, but no significant differences in health care expenditures and utilization. Having a medical home may help improve health care quality for children; losing a medical home may lead to higher utilization of emergency care. © Health Research and Educational Trust.

The authors examined concentrations of lead, cadmium, mercury, manganese, selenium, and chromium in feathers, liver, kidney, heart, and muscle of known-aged laughing gulls (Larus atricilla) that hatched in Barnegat Bay, New Jersey and were collected at John F. Kennedy International Airport, New York 1 to 7 years later. Concentrations differed significantly among tissues, and tissue entered all the regression models explaining the greatest variation in metal levels. Age of bird contributed significantly to the models for lead, cadmium, selenium, and chromium. Although there were significant gender differences in all body measurements except wing length, there were few differences in metalmore » levels. Males had significantly higher lead levels in feathers, and females had significantly higher selenium levels in heart and muscle tissue. For lead, 3-year olds had the highest levels in the heart, liver, and kidney, and levels were lower thereafter. Mercury levels in feathers and heart decreased significantly with age. Cadmium levels increased significantly with age for feathers, heart, liver, and muscle, although there was a slight decrease in the 7-year olds. Selenium levels decreased significantly with age for all tissues. Chromium levels increased with age for liver and heart.« less

This study aimed to characterize anatomical and biochemical properties of owl monkey kidneys in order to provide normal reference values. Sixty-nine Aotus azarai infulatus (45 males and 24 females) were divided into four different age groups (AG1: 3 months-1 year; AG2: 2-3 years; AG3: 4-6 years; and AG4: over 7 years old). The monkeys were evaluated with a serum chemistry profile, focusing on serum creatinine (SCr) and blood urea nitrogen (BUN) and with ultrasound. Mean body mass differed among the age groups. This significance was attributed to AG1 body mass being significantly lower than in AG2 and that in both AG2 and AG3 being significantly lower than in the two older age groups (AG3 and AG4). SCr and BUN concentrations differed significantly between the sexes and SCr level correlated positively with age. In contrast, renal measurements did not differ between males and females. Left and right renal volumes did not differ significantly within age groups, or among AG2, AG3, and AG4. Renal volumes in AG1, however, while not differing from those in AG2, did differ significantly from those in AG3 and AG4. In conclusion, this study provides ultrasonographic reference values for the morphology the kidneys in A. a. infulatus. Evidence is also provided that SCr and BUN levels in owl monkeys are influenced by the sex and age of the individual, factors that should be considered when interpreting test results. © 2012 Wiley Periodicals, Inc.

2017-04-01
The aim of the present study was to assess bone volume changes in maxillary molar regions after delayed implants placement. Patients presented large bone defects after tooth extractions. Reactive soft tissue was left into the defects. No grafts were used. Cone beam computed tomography (CBCT) scans were performed before tooth extractions, at implant placement (at 3 months from extraction) and 3 years after implant placement, bone volume measurements were assessed. Bucco-lingual width showed a statistically significant decrease (p = .013) at implant placement, 3 months after extraction. Moreover, a statistically significant increase (p < .01) was measured 3 years after implant placement. No statistically significant differences (p > .05) were found between baseline values (before extraction) and at 3 years from implant placement. Vertical dimension showed no statistically significant differences (p > .05) at implant placement, 3 months after extraction. Statistically significant differences (p < .0001) were found between baseline values (before extraction) and at 3 months from implant placement as well as between implant placement values and 3 years later. CT scans presented successful outcome of delayed implants placed in large bone defects at 3-year follow-up. © 2016 Wiley Periodicals, Inc.
Enhancing positive attitudes towards disability: evaluation of an integrated physiotherapy program.
Morgan, Prue Elizabeth; Lo, Kristin
2013-02-01
This study explored whether attitudes towards disability in second year undergraduate physiotherapy students could be enhanced by an on-campus integrated curriculum program. A pre-post design was used. Year 2 (pre-clinical) students participated in a 12-week program focused on optimising attitudes towards people with acquired or developmental neurological disability. The Discomfort subscale of the Interaction with Disabled Persons scale, rated on a six-point Likert scale, was applied prior to and at completion of the 12-week program, and compared to year 4 students, just prior to graduation. Qualitative data from year 2 reflective narratives was also gathered. Forty-seven second year and 45 fourth year physiotherapy students participated. The difference in Discomfort subscale scores between weeks 1 and 12 of year 2 was statistically significant (p = 0.0016). The difference in Discomfort subscale scores between year 2 week 1 and year 4 students was also statistically significant (p = 0.040). There was no significant difference in attitudes between students at the end of year 2 and the end of year 4 (p = 0.703). Qualitative data supported the development of more positive attitudes towards neurological disability across the 12 week year 2 pre-clinical program. Student attitudes towards people with acquired and/or developmental neurological disabilities can be enhanced through an on campus integrated curriculum program.

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

We are studying the regional impact of volcanic eruptions that might have caused global cooling using high-quality annual-resolution proxy records of natural phenomena, such as tree-ring widths, and cultural events, such as the dates of the beginning of grape and rye harvests. To do this we need to determine if the year following an eruption was significantly colder and wetter than preceding or subsequent years as measured by any given proxy and if that year is consistently cold and wet across different proxies. The problem is complicated by the fact that normal inter-annual variations in any given proxy can be quite large and can obscure any volcanological impact and by the fact that inter-annual variations for different proxies will have different means and standard deviations. We address the first problem by assuming that on a regional scale, the inter-annual variations of different proxies are at best only weakly correlated and that, in the absence of a volcanological signal, these variations will average out on a regional scale. We address the second problem by renormalizing each record so that it has the same mean and standard deviation over a given time interval. We then sum the re-normalized records on a year-by-year basis and look for years with significantly higher total scores. The method can also be used to assess the statistical significance of an anomalous value. Our initial analysis of records primarily from the Northern Hemisphere shows that the years 1601 and 1816 were significantly colder and wetter than any others in the past 500 years. These years followed the eruptions of Huayanaputina in Chile and Tambora in Indonesia, respectively, by one year. The years 1698 and 1837 also show up as being climatologically severe although they have not (yet) been associated with specific volcanic eruptions.

Fifty children 7 years of age (29 girls, 21 boys), 53 children 10 years of age (29 girls, 24 boys), and 36 young adults (19 women, 17 men) performed a computerized event-based prospective memory task. All 3 groups differed significantly in prospective memory performance, with adults showing the best performance and with 7-year-olds showing the poorest performance. We used a formal multinomial process tree model of event-based prospective memory to decompose age differences in cognitive processes that jointly contribute to prospective memory performance. The formal modeling results demonstrate that adults differed significantly from the 7-year-olds and the 10-year-olds on both the prospective component and the retrospective component of the task. The 7-year-olds and the 10-year-olds differed only in the ability to recognize prospective memory target events. The prospective memory task imposed a cost to ongoing activities in all 3 age groups.

Several recent studies have reported that favorable clinical results and a high level of patient satisfaction can generally be obtained with no increased risk of complications after single-bundle anterior cruciate ligament (ACL) reconstruction performed in patients >40 years of age. However, no studies have yet clarified the age-based differences in clinical outcomes after double-bundle reconstruction. To compare clinical outcomes after double-bundle ACL reconstruction using hamstring tendon hybrid grafts between patients in 2 different age groups: ≥40 years and <40 years. Cohort study; Level of evidence, 3. A retrospective study was conducted using 96 patients (48 men, 48 women ; mean age, 37 years) who underwent unilateral ACL reconstruction between 2008 and 2011. These patients were divided into 2 groups: group M included patients ≥40 years of age (n = 40 patients), and group Y included patients <40 years of age (n = 56 patients). All patients underwent the same anatomic double-bundle ACL reconstruction procedure. Clinical outcomes were evaluated at 2 years after surgery. Tunnel enlargement was also evaluated by computed digital radiography at 1 week and 2 years after surgery. Mean postoperative side-to-side differences in anterior laxity were 0.5 ± 1.9 mm and 1.2 ± 1.5 mm in groups M and Y, respectively; there was a significant difference between the 2 groups ( P = .039). There were no significant differences between the groups in Lysholm knee scores, International Knee Documentation Committee (IKDC) scores, or peak muscle torque of the hamstring. On the other hand, peak muscle torque of the quadriceps was significantly lower in group M (81%) than in group Y (89%) ( P = .025). With respect to femoral tunnel enlargement, the posterolateral tunnel in group M was significantly larger than that in group Y on anteroposterior and lateral radiographs ( P = .015 and P = .002, respectively). Equivalent clinical outcomes were seen between the 2 age groups after double-bundle ACL reconstruction. Postoperative anterior laxity was significantly less in older patients than in younger patients, however, older patients had significantly less quadriceps muscle strength than younger patients. Surgeons should be aware of residual muscle weakness and tunnel enlargement when performing double-bundle ACL reconstruction in older patients.

The aim of this study was to map out the developmental curve of the orbital volume of Chinese children aged 1-15 years. CT scanning was performed on 109 children and the orbital volume, interlateral orbital rim distance (IORD), and extent of exophthalmos were measured on the CT images and plotted against age. The development of the orbit structure followed a biphasic pattern. The first growth phase was before 3 years and the second growth phase was between 7 years and 12 years of age. The growth speed in the first phase was about 3 times that of the second one (first vs second phase: 2.28 cm 3 /year vs 0.67 cm 3 /year for orbital volume, 5.01 mm/year vs 1.57 mm/year for IORD, 1.29 mm/year vs 0.42 mm/year for the exophthalmos). During development, there was no significant difference between the left and right orbits. There was no significant difference between boys and girls before 12 years of age. However, after 12 years of age, boys had significantly larger orbital volumes (22.16±2.28 cm 3 /year vs 18.57±1.16 cm 3 /year, p<0.001) and a greater IORD (96.29±3.18 mm/year vs 91.00±4.54 mm/year, p<0.001) than girls. In Chinese children, the development of orbital volume follows a biphasic pattern and a sex difference becomes significant after the age of 12 years. Published by the BMJ Publishing Group Limited.

Different guidelines and frameworks like the CanMEDs model or entrustable professional activities (EPAs) describe competencies required for successful and professional work of residents. Not all competencies are of equal importance for graduates when they start their residency. The aim of this study was to evaluate the relevance of different competencies for a first year resident from the perspective of physicians and medical students. In an online study, 178 of 475 surgeons and internists including residents and attendings and 102 of 728 first and last year undergraduate medical students from the University Medical Center Hamburg-Eppendorf ranked 25 competencies according to their relevance for entrustment decisions in first year residents. The rankings of the competencies by residents and attendings and by first year and last year medical student were compared. Additionally, the rankings were also compared to the literature. Physicians and medical students rated 'Responsibility' as the most important competency for first year residents. Physicians ranked 'Teamwork and collegiality' and 'Structure, work planning and priorities' within the top 10 competencies significantly higher than medical students. The competency ranks between attendings and residents only showed one significant difference between attendings and residents, where 'Coping with mistakes', was ranked significantly higher by residents. Medical students ranked 'Active listening to patients', 'Advising patients' and 'Handling emotions of patients and their relatives' significantly higher than physicians. Final year students ranked 'Structure, work planning and priorities', 'Coping with mistakes', and 'Verbal communication with colleagues and supervisors' significantly higher than first year students. Even though physicians and medical students agree that 'Responsibility' is the most important competency for entrustment decisions in the first year of residency, medical students rate competencies regarding patient communication very highly while physicians rate competencies required for patient managements significantly higher for entrustment decision. Undergraduate medical curricula seem to prepare students well with respect to patient-centeredness but need to be developed more specifically to prepare students equally well for patient management competencies which are required in the first year of residency for entrustment decisions from the attendings perspective.

To examine how the inclusion (+) or exclusion (-) of inactivated Leptospira antigens in a vaccine for canine parvovirus type 2 (CPV-2), canine distemper virus (CDV) and canine adenovirus type 2 (CAdV-2) affects antibody titres to CPV-2, CDV and CAdV-1 antigens, household dogs were vaccinated with commercially available vaccines from one of three manufacturers. CPV-2, CDV and CAdV-1 antibody titres were measured 11 to 13 months later and compared within three different age groups and three different bodyweight groups. There were significant differences between CPV-2 antibody titres in dogs vaccinated with (+) vaccine and those vaccinated with (-) vaccine for two products in the two-year-old group and for one product in the greater than seven-year-old group; no significant differences were seen that could be attributed to bodyweight. No differences in CDV antibody titres were observed within age groups, but a significant difference was seen in the 11 to 20 kg weight group for one product. Significant differences in CAdV-1 antibody titres were seen for one product in both the two-year-old group and the ≤10 kg weight group.

A comparative study was conducted on the needles stable carbon isotope composition (delta13 C), specific leaf area (SLA), and dry matter content (DMC) of 19-year-old Pinus sylvestris var. mongolica trees in a sparse wood grassland in the south edge of Keerqin Sandy Land under the conditions of extreme drought and extreme wetness, aimed to understand the water use of Pinus sylvestris under the conditions of extreme precipitation. The soil water content and groundwater level were also measured. In the dry year (2009), the soil water content in the grassland was significantly lower than that in the wet year (2010), but the delta13C values of the current year-old needles had no significant difference between the two years and between the same months of the two years. The SLA of the current year-old needles was significantly lower in the dry year than in the wet year, but the DMC had no significant difference between the two years. Under the conditions of the two extreme precipitations, the water use efficiency of the trees did not vary remarkably, and the trees could change their needles SLA to adapt the variations of precipitation. For the test ecosystem with a groundwater level more than 3.0 m, extreme drought could have no serious impact on the growth and survival of the trees.

2004-09-01
To evaluate the opaquing capacity, color compatibility and stability of IPS Empress all-ceramic veneers. A total of 86 IPS Empress all-ceramic veneers were made for 18 patients. The patients were divided into three groups: Group A was tetracycline teeth, 64 veneers for 5 patients; Group B was non-tetracycline teeth, 22 veneers for 13 patients; Group C was 22 natural vital teeth with normal color as control group. Before and after veneers were inserted, ShadeEye NCC was employed to obtain L * a * b * values of each tooth. The values of cemented veneers used as the baseline, the L * a * b * values of each veneer were measured half a year, 1 year, and 2 years after restoration respectively. All L * a * b * values at different evaluation times were analyzed by SPSS 10.0. Before and after veneers were restored, the L * a * b * values of both Group A and Group B were significantly different, the color difference being 5.01 and 4.15 respectively. The color difference between Group A and selected shade guides was 2.45. Compared with the baseline value, the L * value of Group A significantly decreased 2 years after restoration, but the DeltaE of different evaluation times was not significantly different. The color difference between Group B and Group C was 0.22 and there was no significant color difference after restoration. IPS Empress all-ceramic veneers have excellent opaquing capacity, color compatibility and stability to non-tetracycline teeth. To tetracycline teeth IPS Empress all-ceramic veneers have a certain opaquing capacity, but they cannot completely match with shade guides; the L * value is significantly different after restoration and further studies are needed to evaluate its color effect.

To investigate the occupational health of the workers simultaneously exposed to acrylonitrile, epoxyethane, epoxypropane, and styrene. A questionnaire survey was conducted in 70 front-line workers simultaneously exposed to acrylonitrile, epoxyethane, epoxypropane, and styrene (exposure group) and 50 managers (control group) in a polyether manufacturer; in addition, air monitoring at workplace and occupational health examination were also performed. The obtained data were analyzed. The female workers in exposure group and the spouses of male workers in exposure group had significantly higher spontaneous abortion rates than their counterparts in control group (P < 0.01). The exposure group had a significantly higher abnormal rate of blood urea nitrogen than the control group (P < 0.01). The workers with different polyether-exposed working years had significantly higher mean levels of DNA damage than the control group (P < 0.01); the workers with not less than 5 and less than 20 polyether-exposed working years and those with not less than 20 polyether-exposed working years had significantly higher mean micronucleus rates than the control group (P < 0.01); there were no significant differences in overall chromosome aberration rate and mean level of DNA damage between each two groups of workers with different polyether-exposed working years (P > 0.05); the workers with not less than 5 and less than 20 polyether-exposed working years and workers with not less than 20 polyether-exposed working years had significantly higher mean micronucleus rates than those with less than 5 polyether-exposed working years (P < 0.01). Simultaneous exposure to acrylonitrile, epoxyethane, epoxypropane, and styrene causes occupational hazards among the workers in polyether manufacturer.

A bioenergetic model of juvenile pink salmon ( Oncorhynchus gorbuscha) was used to estimate daily prey consumption and growth potential of four ocean habitats in the Gulf of Alaska during 2001 and 2002. Growth potential was not significantly higher in 2002 than in 2001 at an alpha level of 0.05 ( P=0.073). Average differences in growth potential across habitats were minimal (slope habitat=0.844 g d -1, shelf habitat=0.806 g d -1, offshore habitat=0.820 g d -1, and nearshore habitat=0.703 g d -1) and not significantly different ( P=0.630). Consumption demand differed significantly between hatchery and wild stocks ( P=0.035) when examined within year due to the interaction between hatchery verses wild origin and year. However, the overall effect of origin across years was not significant ( P=0.705) due to similar total amounts of prey consumed by all juvenile pink salmon in both study years. We anticipated that years in which ocean survival was high would have had high growth potential, but this relationship did not prove to be true. Therefore, modeled growth potential may not be useful as a tool for forecasting survival of Prince William Sound hatchery pink salmon stocks. Significant differences in consumption demand and a two-fold difference in nearshore abundance during 2001 of hatchery and wild pink salmon confirmed the existence of strong and variable interannual competition and the importance of the nearshore region as being a potential competitive bottleneck.

Tofade, Toyin S; Brueckl, Mark; Ross, Patricia A
2017-10-01
Objective. To evaluate the rotation capacity at the University of Maryland School of Pharmacy and see if the implementation of clinical track programs across the state correlates to an increase in rotation capacity for the school. Methods. The following information was collected: number of preceptors over the years in the school's experiential learning program, number of clinical track programs from 2012 to 2015, rotation type, availability submissions per rotation type per year, and availability submissions per hospital participant in the clinical track program per year. The rotation capacity and rotation types from 2012 to 2015 academic years were assessed and compared to see if there was any impact on the clinical track programs implemented. Results. There was no statistically significant difference in the frequency distribution of rotation types among all sites from 2012 through 2015 academic years. However, there was a statistically significant difference in the total number/capacity of rotations from 2012 to 2015 academic years. There were also statistically significant differences in the rotation capacity in all sites except for three sites. Conclusion. Adding clinical track programs can help increase the capacity of a school's clinical rotations.
Seasonality and synchrony of reproduction in three species of nectarivorous Philippines bats
Heideman, Paul D; Utzurrum, Ruth CB
2003-01-01
Background Differences among species and among years in reproductive seasonality (the tendency for clusters of events to fall at approximately the same point in each year) and synchrony (amount of clustering of events within a year) have been intensively studied in bats, but are difficult to assess. Here, we use randomization methods with circular statistics to test for synchrony and seasonality of reproduction in three species of nectarivorous megachiropteran bats on Negros Island in the central Philippines. Results In Rousettus amplexicaudatus, estimated dates of birth were both highly synchronous and highly seasonal. In Macroglossus minimus, estimated births were seasonal and significantly clustered within years, but within each year births occurred over a broad period, indicating a low level of synchrony. In Eonycteris spelaea, estimated births were also seasonal and had statistically significant synchrony, with birth periods within years intermediate in synchrony between R. amplexicaudatus and M. minimus. All three species had a similar seasonal pattern, with two birth periods in each year, centered on March or April and August or September. In one species, R. amplexicaudatus, primigravid females (in their first pregnancy) produced their young in June and July, a birth period significantly different in timing from the two birth periods of older adult females. This more conservative pattern of young females may allow higher survival of parents and offspring at cost of a lost reproductive opportunity. There was weak evidence that in some years primigravid females of M. minimus might differ in timing from older adults. There were few significant differences in reproductive timing among different years, and those differences were generally less than two weeks, even during a severe drought in the severe el Niño of 1983. Conclusion The results suggest that these species follow an obligately seasonal pattern of reproductive timing with very little phenotypic plasticity. The resampling methods were sensitive to differences in timing of under two weeks, in some cases, suggesting that these are useful methods for analyses of seasonality in wild populations of bats.

Six treatments of eastern Kansas tallgrass prairie - native prairie, hayed, mowed, grazed, burned and untreated - were studied to examine the biophysical effects of land management practices on grasslands. On each treatment, measurements of plant biomass, leaf area index, plant cover, leaf moisture and soil moisture were collected. In addition, measurements were taken of the Normalized Difference Vegetation Index (NDVI), which is derived from spectral reflectance measurements. Measurements were taken in mid-June, mid-July and late summer of 1990 and 1991. Multivariate analysis of variance was used to determine whether there were differences in the set of variables among treatments and years. Follow-up tests included univariate t-tests to determine which variables were contributing to any significant difference. Results showed a significant difference (p < 0.0005) among treatments in the composite of parameters during each of the months sampled. In most treatment types, there was a significant difference between years within each month. The univariate tests showed, however, that only some variables, primarily soil moisture, were contributing to this difference. We conclude that biomass and % plant cover show the best potential to serve as long-term indicators of grassland condition as they generally were sensitive to effects of different land management practices but not to yearly change in weather conditions. NDVI was insensitive to precipitation differences between years in July for most treatments, but was not in the native prairie. Choice of sampling time is important for these parameters to serve effectively as indicators.

The purpose of this study is to determine the lifetime prevalence of past injuries in incoming first year football players in a Division 1 college football team. Pre-participation questionnaires from 605 first-year football players over 20 years (1996-2015) were examined to determine the prevalence of concussions, stingers, fractures, and musculoskeletal surgeries sustained before playing at the collegiate level. Players were grouped by position: wide receiver and defensive back (WR/DB), offensive and defensive linemen (OL/DL), all other positions (OP), and unknown (UKN). Prevalence of injuries by year and position was compared using Pearson's χ 2 Test (p < 0.05). The reported lifetime prevalence is as follows: concussion (21%), stinger (23%), musculoskeletal surgery (23%), and fracture (44%). There were no significant differences in lifetime prevalence of concussions (p = 0.49), stingers (p = 0.31), fractures (p = 0.60), or musculoskeletal surgeries (p = 0.97) based on position. There were also no significant differences in the lifetime prevalence of concussions (p = 0.14), musculoskeletal surgeries (p = 0.50), or fractures (p = 0.59) based on year. However, there was a significant difference in the lifetime prevalence of stingers based on year (p < 0.001). There was an expectation to observe an increase in injury prevalence by entering year, but this was not seen. A decrease in stingers was actually observed, but there was no significant difference among any other injury recorded. These results do not support the perception that football injuries are on the rise. Under reporting is a significant concern as players may fear disqualification or that they are evaluated by the coaching staff based on their medical history. More research is needed to confirm lifetime injury prevalence and evaluate differences over time among football players.

Management of recurrent respiratory papillomatosis (RRP) in adults has evolved to include office-based laser techniques. To determine whether demographic or disease characteristics differ between patients undergoing office-based (office group) vs traditional operating room (OR group) surgical approaches for RRP. This study was a medical record review of adult patients with RRP treated between January 2011 and September 2013 at a tertiary care center. Patients were divided into 2 groups according to the setting in which the patient had the most procedures during the past 2 years. Demographic and disease characteristics were compared between patients receiving predominantly office-based vs predominantly OR management. Of 57 patients (47 male and 10 female, with a mean [SD] age of 53.5 [16.4] years) treated during the 2-year period, 34 patients underwent predominantly office-based management and 23 patients underwent predominantly OR management. Sex, age, and weight were not statistically significantly different between the 2 groups. Patients in the OR group had a younger age at RRP diagnosis (mean [SD], 28.7 [22.0] years in the OR group and 45.5 [20.5] years in the office group), with a mean difference of 16.8 years (95% CI, -28.3 to -5.4 years). Patients in the OR group also had a significantly higher Derkay score (mean [SD], 15.1 [5.7] in the OR group and 10.7 [5.0] in the office group), with a mean difference of 4.4 (95% CI, 1.6-7.3). No statistically significant differences in comorbidities were observed between the 2 groups except for type 1 or 2 diabetes, which was more common in the OR group. There were 5 patients (22%) with diabetes in the OR group and 1 patient (3%) with diabetes in the office group, with a mean difference of 19% (95% CI, 2.7%-35%). In a subanalysis that excluded patients with juvenile-onset RRP, Derkay score (mean [SD], 13.9 [4.5] in the OR group and 10.8 [5.1] in the office group), with a mean difference of 3.1 (95% CI, 0.5-6.1), and the incidence of diabetes (25% [4 of 16] in the OR group and 3% [1 of 31] in the office group), with a mean difference of 22% (95% CI, 3%-40%), remained significantly higher in the OR group, while age at diagnosis of RRP was no longer statistically significant (mean [SD], 40.2 [15.6] years in the OR group and 49.6 [16.4] years in the office group), with a mean difference of 9.4 years (95% CI, -19.4 to -0.7 years). There were no sex or age differences between patients with RRP treated in the office compared with those treated in the OR. Patients with earlier age at diagnosis of RRP and greater disease severity were more likely to be managed in the OR.

To analyze the distribution of the musculoskeletal disorders, work load and working postures in different factories, gender, education levels, age and working years among manufacturing workers. In a cross-sectional study of 5134 manufacturing workers in 12 factories, the morbidities for musculoskeletal disorders in one year period were measured with questionnaires. The morbidities for musculoskeletal disorders in body sites: waist, neck, shoulder, wrist, ankle/feet, knee, hip/buttocks and elbows were 59.7%, 47.9%, 38.1%, 33.7%, 26.9%, 25.4%, 15.2%, and 14.9%, respectively in one year period. There were significant differences of morbidities for musculoskeletal symptoms in body sites of workers among different factories (P < 0.05 or P < 0.01). The morbidities of musculoskeletal symptoms in elbows, waist, wrists and ankle/feet of the workers in refractory material and chemical fiber factories were higher than those in other factories, the morbidities for musculoskeletal symptoms of workers in garments and diamond factories were lower than those in other factories. The morbidities for musculoskeletal symptoms in neck, shoulders and wrists of female workers were significantly higher than those of male workers (P < 0.01). There were significant differences of the morbidities for musculoskeletal symptoms in body sites among workers with different educational levels (P < 0.05 or P < 0.01). There were significant differences of the morbidities for musculoskeletal symptoms in neck, shoulders, wrists, hip/buttocks and knee among groups with different age or different working years (P < 0.01), and the morbidities for musculoskeletal symptoms increased with age and working years. The proportions of unhealthy working postures and high working load among workers in refractory material and chemical fiber factories were higher; but those in garments and diamond factories were lower. The morbidities for musculoskeletal symptoms in waist, neck, shoulder and wrists of workers in manufacturing workers were higher; the gender, education level, age and working years could influenced the morbidities for musculoskeletal disorders.
Local survival of Dunlin wintering in California
Warnock, N.; Page, G.W.; Sandercock, B.K.
1997-01-01
We estimated local annual survival of 1,051 individually color-banded Dunlin (Calidris alpina) at Bolinas Lagoon, California from 1979 to 1992. Resighting rates for birds banded as adults varied significantly among years, and resighting rates for first-year birds varied by sex and year. No significant differences in local survival rates were found between males and females in any age classes. First-year birds had lower local survival rates than adults. We suspect that raptor predation accounted for much of this difference and other variation in survival rates. Adult Dunlin had lower local survival rates in the year of capture than in subsequent years. Variation in resighting of some groups of individuals including transient Dunlin may account for some differences. However, capture and release of Dunlin may induce short-term behavioral changes that increase the risk of depredation by avian predators within the first few days after capture.

It has been suggested that people with autistic spectrum disorder (ASD) have altered development (and connectivity) of limbic circuits. However, direct evidence of anatomical differences specific to white matter pathways underlying social behaviour and emotions in ASD is lacking. We used Diffusion Tensor Imaging Tractography to compare, in vivo, the microstructural integrity and age-related differences in the extended limbic pathways between subjects with Asperger syndrome and healthy controls. Twenty-four males with Asperger syndrome (mean age 23+/-12 years, age range: 9-54 years) and 42 age-matched male controls (mean age 25+/-10 years, age range: 9-54 years) were studied. We quantified tract-specific diffusivity measurements as indirect indexes of microstructural integrity (e.g. fractional anisotropy, FA; mean diffusivity, MD) and tract volume (e.g. number of streamlines) of the main limbic tracts. The dissected limbic pathways included the inferior longitudinal fasciculus, inferior frontal occipital fasciculus, uncinate, cingulum and fornix. There were no significant between-group differences in FA and MD. However, compared to healthy controls, individuals with Asperger syndrome had a significantly higher number of streamlines in the right (p=.003) and left (p=.03) cingulum, and in the right (p=.03) and left (p=.04) inferior longitudinal fasciculus. In contrast, people with Asperger syndrome had a significantly lower number of streamlines in the right uncinate (p=.02). Within each group there were significant age-related differences in MD and number of streamlines, but not FA. However, the only significant age-related between-group difference was in mean diffusivity of the left uncinate fasciculus (Z(obs)=2.05) (p=.02). Our preliminary findings suggest that people with Asperger syndrome have significant differences in the anatomy, and maturation, of some (but not all) limbic tracts.

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

To evaluate students' perceptions of the learning environment and to assess any differences in perception related to students' performance and their year of study. A descriptive cross-sectional study was performed of 638 students from the second, sixth and tenth semesters at the Faculty of Medicine at Gezira University, Sudan. This study employed the Arabic-translated Dundee Ready Education Environment Measure. The main predictor variables were the study year and academic performance. Descriptive statistics and one-way analysis of variance with a post hoc Tukey-Kramer multiple comparisons test were used for data analysis. The overall score for this study was 122/200 (SD=16.6), indicating a positive perception of the learning environment. The overall mean score was 109.94/200 (SD=21.2) for Semester 2 students, 122.9/200 (SD=20.29) for Semester 6 students, and 116.53 (SD=20.12) for Semester 10 students, reflecting a significant difference in students' perceptions in different years of study (F (2,2422) = 3.21, p=0.04). There was also a significant difference between the mean overall scores with respect to academic performance. High-achieving students' mean DREEM score was 126 (SD=24.4); while low-achieving students' mean DREEM score was 102 (SD=26.25) (F (2,2453) = 3.53, p=0.029). High achievers' perceptions of the learning environment are significantly better than those of low achievers. A significant difference was observed between students in different years of study. The differences in students' academic performance should be further investigated, targeting specific domains. A large-scale study is required to differentiate between the weakness and the strength of each academic level.

BACKGROUND & AIMS The reason that women have a lower prevalence of duodenal ulcer is not clear. We investigated whether estrogen regulates human duodenal bicarbonate secretion (DBS) and whether this process accounts for sex differences in the prevalence of duodenal ulcer. METHODS We performed an epidemiological study to correlate duodenal ulcer prevalence with sex and age. Proximal DBS was measured from healthy subjects. Estrogen receptor expression was examined in human duodenal mucosa by immunoblot and immunohistochemical analyses. RESULTS Among women, the prevalence of duodenal ulcer was significantly lower than among men. The reduced prevalence was greatest among premenopausal women (20–49 years), who were 3.91–5.09-fold less likely to develop duodenal ulcers than age-matched men; the difference was reduced to ≤1.32-fold among subjects 60 years or older. Premenopausal (20–29 years), but not post-menopausal (60–69 years) women, had significantly higher basal and acid-stimulated DBS than the age-matched men. Basal and acid-stimulated DBS in premenopausal women (20–29 years) were significantly higher than in post-menopausal women (60–69 years), whereas there were no significant differences in basal or acid-stimulated DBS between men that were 20–29 years old or 60–69 years old. Serum levels of estradiol changed in parallel with basal and acid-stimulated DBS during the physiological menstrual cycle in premenopausal women. 17β-estradiol-stimulated DBS was independent of age or sex. Estrogen receptors- and - were detected on plasma membrane and in cytosol of human duodenal epithelial cells. CONCLUSIONS Estrogen regulates human DBS, which could reduce the risk for duodenal ulcer in women and contribute to sex differences in prevalence of duodenal ulcer. PMID:21699784

This study aims to compare patient, tumor, treatment-related factors and survival between young (<45 years) and old (>45 years) Indian colorectal cancer (CRC) patients. Total 778 patients of CRC were registered at tertiary cancer center in India between 1 August 2013 and 31 July 2014. Patients were followed up for median period of 27.73 months. Data regarding patient, tumor, treatment and survival-related factors were collected. Patients were divided in young (≤45 years) and old (>45 years) age groups. Statistical analysis was done with SPSS software version 23. Young age group patients presented more commonly with poor histology, node-positive disease, and rectal site. Younger age group patients received multiple lines of neoadjuvant treatment. There was no significant overall survival difference in both groups of patients. On stratified stage-wise analysis, no significant overall survival (OS) difference was found between two groups (young vs old-1- and 3-year OS: 85.2 and 61.5% vs 81.5 and 64.5%, respectively; P = 0.881). On univariate analysis, gender, performance status, site, stage, differentiation, TRG, CRM status, signet ring type, and CEA level were significant prognostic factors. In disease-free survival (DFS) analysis, it is found that there is statistically significant difference in DFS (young vs old: 1 and 3 years; 77.6 and 62.8% vs 85.8 and 74.1%, respectively; P value, 0.02), but when OS was analyzed for same group of patient, there was no statistical difference ( P = 0.302). This study confirms the high incidence rates of CRC in young Indian patients. There is no OS difference between two age groups. In operated group of patients, there is higher DFS in older patients but no OS advantage at 3 years follow-up. Further long-term follow-up is required to see any OS difference.

This study examined the differences between faculty and trained standardized patient (SP) evaluations on student professionalism during a second-year podiatric medicine standardized simulated patient encounter. Forty-nine second-year podiatric medicine students were evaluated for their professionalism behavior. Eleven SPs performed an assessment in real-time, and one faculty member performed a secondary assessment after observing a videotape of the encounter. Five domains were chosen for evaluation from a validated professionalism assessment tool. Significant differences were identified in the professionalism domains of "build a relationship" ( P = .008), "gather information" ( P = .001), and share information ( P = .002), where the faculty scored the students higher than the SP for 24.5%, 18.9%, and 26.5% of the cases, respectively. In addition, the faculty scores were higher than the SP scores in all of the "gather information" subdomains; however, the difference in scores was significant only in the "question appropriately" ( P = .001) and "listen and clarify" ( P = .003) subdomains. This study showed that professionalism scores for second-year podiatric medical students during a simulated patient encounter varied significantly between faculty and SPs. Further consideration needs to be given to determine the source of these differences.

The literature relating to psychiatric nurses' attitudes towards treatment is reviewed and a study reported which (a) compared the attitudes towards treatment of 51 trainee psychiatric nurses at different points in their training (in their first year, in their second year, and in their third year) using the Attitudes to Treatment Questionnaire (ATQ) revised by Caine et al., and (b) investigated the relationship between conservatism/radicalism as measured by the Wilson-Patterson Attitude Inventory (WPAI) and attitudes towards treatment. The results indicated that the groups differed significantly in their attitudes towards treatment, the first year group being significantly less liberal, having a more physical attitude towards treatment, than the second and third year groups. Overall there was no significant correlation between conservatism and attitudes to treatment found. However, there was a highly significant correlation between these two variables for the third year group of students. For this group, higher conservatism scores were associated with less liberal attitudes to treatment. The implications of these findings are discussed and suggestions made for further research.

i) To determine the prevalence of smoking among the community aged 15 and above in Kg. Jenderam Hilir in Sepang District, Selangor state. ii) To determine the relationship between smoking and age, sex, household income and education. iii) To determine the parental and peer influence on smoking in Kg Jenderam Hilir. A study was conducted in Kg. Jenderam Hilir, Sepang. All residents aged 15 years and above from all the 381 households of Kg. Jenderam Hilir were included in this study. A standardized pre-tested structured questionnaire was used in this study. Out of 894 respondents interviewed 69% were males compared to 3.9% of the females (overall 33.6%) reported to have smoked at least once in his/her lifetime. The difference was statistically significant. The mean duration of smoking was 17.7 years. The age at which smoking was first attempted ranged from 4 years to 51 years with a mean of 18.7 years. The mean initiation age for the males was significantly lower as compared to the mean initiation age for the females. The prevalence of current smokers was significantly higher amongst males (52.8%) as compared to the females (1.4%). The prevalence of smoking among current smokers increased with age (p < 0.01). There was no significant difference in the prevalence of smoking by household income and educational level. The mean number of cigarettes smoked by males was significantly higher than the females (p < 0.05). The mean duration of smoking among current smokers was 20 years. There was a significant difference in the level of addiction to smoking and the duration of smoking (p < 0.05). The high level of addiction increased with the duration of smoking (p < 0.05). Sixty five percent of the current smokers reported to have tried to quit smoking while 26% of ever smokers had reported to quit smoking and remained nonsmokers. The quit ratio was calculated to be 26.0%. The quit ratio was 52.6% among those with college or university education. There was a significant difference in the quit ratio by education level (p < 0.01). There was no significant difference in smokers whose parents were smokers as compared to nonsmokers whose parents were smokers. However, there was a significant association between smoking and peer influence (p < 0.01).

Approximately 25% of working-aged Americans with disabilities work full or part time, yet still face discrimination despite the passing of the American's with Disabilities Act (ADA) over 20 years ago. To determine if the proportion of allegations of ADA Title I workplace discrimination with merit closed at any year between 1993 and 2008 differs among Whites, African Americans, Hispanics, and Asians; to determine if there was a change over time from 1993 to 2008 in merit closure rate within each race/ethnicity group; and to determine whether changes over time between 1993 and 2008 in the merit closure rate differ among the race/ethnicity groups. Logistic regression was used for this cross-sectional panel study to model the merit closure rate for each ethnic group from 1993 to 2008 using 318,587 charging parties from the EEOC database. All ethnic groups exhibited significant changes over time in the merit closure rate. There were significant differences in the closure rates among the race/ethnicity groups specifically at closure years 1995-2000, 2002, 2003, and 2006. Finally, there was evidence that the trends in merit closure rates over time differed significantly among the race/ethnicity groups. There was significant evidence that the proportion of claims closed with merit was significantly different among the racial/ethnicity groups.

Little is known about the role of herpes simplex virus (HSV) type 1 (HSV1) in the epidemiology of genital herpes in Canada. Data on herpes viral cultures for two consecutive years obtained from L'Hôpital Dr GL Dumont, which performs all the viral culture testing in New Brunswick, were reviewed. It was hypothesized that HSV1 was the main cause of genital herpes in New Brunswick. Samples of genital origin sent to the laboratory for HSV culture testing between July 2006 and June 2008 were analyzed. Samples from an unspecified or a nongenital source were excluded from analysis. Multiple positive samples collected from the same patient were pooled into a single sample. HSV was isolated from 764 different patients. HSV1 was isolated in 62.6% of patients (male, 55%; female, 63.8%). HSV1 was isolated in 73.2% of patients 10 to 39 years of age and in 32% of patients ≥40 years of age. The difference in rates of HSV1 infection between the 10 to 39 years of age group and the ≥40 years of age group was statistically significant (P<0.001 [χ(2)]). In a similar Canadian study performed in Nova Scotia, HSV1 was recovered in 53.7% of positive cultures (male, 36.7%; female, 58.1%). The rates of HSV1 infection reported by this study and the present study were significantly different (P<0.001 [χ(2)] for male, P=0.012 for female). In New Brunswick, HSV1 is the dominant type of HSV isolated in samples collected from a genital site. Significant rate differences were demonstrated between the groups 10 to 39 years of age and ≥40 years of age.

Farbu, Elisabeth; Gilhus, Nils Erik
2002-04-01
Eighty former poliomyelitis patients and the sibling nearest in age and of same sex were examined with matched-pair analysis to evaluate the effect of previous poliomyelitis (polio) on social factors and general health. Fifty-four pairs with women (68 %), and 26 pairs with men (32 %) with a mean age 60.4 years were included. Data were collected by questionnaire. There was no significant difference in length of education between patients and siblings (categories < 8 years, 8-12 years, and > 12 years). Employment rate at age 40 years was 78 % for patients and 88 % for siblings (full-time or part-time); this difference was not significant. Educational options were considered to have been excellent by 38 % of the patients and 26 % of the siblings (not significant), with a fair agreement within the pairs (kappa=0.31). There was no significant difference regarding professional options; rated as excellent by 33 % of patients, and 28 % of siblings, with a fair agreement (kappa=0.25) also for this issue. Perception of general health today expressed on a horizontal VAS-scale (0-10) was significantly lower among the patients than the siblings, mean values of 5.8 and 6.8 (P < 0.001) respectively. Patients also reported a lower quality of life (P=0.03), and less energy for leisure activities (P=0.008). Post polio symptoms like muscular and articular pain, and abnormal tiredness were more common among patients than siblings, whereas there was no difference regarding coexisting illness. In conclusion, polio patients and their siblings reckoned their educational and professional options to have been at the same level. The patients were well educated and employed to the same degree up to the age of 40 years, but now at a higher age reported reduced general health.

To compare the clinical outcomes of sigmoid and ileal neobladders (NBs) created following radical cystectomy. This study included 90 and 144 Japanese patients undergoing radical cystectomy and orthotopic NB reconstruction with a sigmoid and ileal segment, respectively. Postoperative clinical outcomes between the sigmoid and ileal NB groups (SNBG and INBG) were compared. In this series, 110 early and 51 late complications occurred in 71 and 41 patients, respectively; however, there was no significant difference in the incidence of complications between SNBG and INBG. At 1 year postoperatively, there were no significant differences in the proportion of spontaneous voiders and the continence status between these 2 groups; however, despite the lack of significant differences in the maximal flow rate and voided volume, the post-void residual in SNBG was significantly smaller than that in INBG. Voiding functional outcomes at 5 years postoperatively were also obtained from 28 and 49 in SNBG and INBG, respectively. Although there were no significant changes in the functional outcomes in SNBG, the proportion of spontaneous voiders and post-void residual in INBG at 5 years postoperatively were significantly poorer than those at 1 year postoperatively. Furthermore, the postoperative health-related quality of life assessed by a Short-Form 36 survey did not show any significant differences in all 8 scores between these 2 groups. Both types of NB reconstruction resulted in comparatively satisfactory outcomes; however, the voiding function, particularly that on long-term follow-up, in SNBG appeared to be more favorable than that in INBG.

This study examines facial tissue depth in Canadian Aboriginal children. Using ultrasound, measurements were taken at 19 points on the faces of 392 individuals aged 3-18 years old. The relationships between tissue thickness, age, and sex were investigated. A positive linear trend may exist between tissue thickness and age for Aboriginal females and males at multiple points. No points show significant differences in facial tissue depth between males and females aged 3-8 years old; seven points show significant differences in facial tissue depth between males and females aged 9-13 years old; and five points show significant differences in facial tissue depth between males and females aged 14-18 years old. Comparisons were made with White Americans and African Nova Scotians. These data can assist in 3-D facial reconstructions and aid in establishing an individual's identity. Previously, no data existed for facial tissue thickness in Canadian Aboriginal populations. © 2013 American Academy of Forensic Sciences.

To investigate natural spontaneous menopausal age, menstruation span and their relationship with menarche age and parity in Pudong district of Shanghai. From Jan 2007 to Jul 2008, 15 083 spontaneous menopause women undergoing cervical cancer screening were enrolled in this study. The questionnaire included menarche age, parity, spontaneous menopausal age and menstruation span. Those women were divided into four groups based on age, which were group of 56 - 60, 61 - 65, 66 - 70 and more than 70.Analysis of variance (ANOVA) was used for comparing difference between menopausal age and menstruation span. Multiple factor regressions was used to analyze the relationship between menarche age, parity and menopausal age and menstruation span. (1) Spontaneous menopausal age: the minimum was 29 years old, the maximum was 61 years old, and the mean age was (50.6 ± 3.7) years old. The mean spontaneous menopause age were (50.9 ± 3.4), (50.7 ± 3.7), (50.0 ± 4.1), (49.6 ± 4.0) years in groups of 56 - 60, 61 - 65, 66 - 70 and more than 70 years. With the increasing age range in four groups, the increasing trends of menopausal age were observed, which the difference of 1.36 year was shown between groups of 56 - 60 and more than 70 years. (2) Menstruation span: the mean of menstruation span was (34.3 ± 4.1) years, which the minimal age of 12 years and maximal age of 48 years were recorded. (34.6 ± 3.8), (34.3 ± 4.1), (33.9 ± 4.6), (33.2 ± 4.5) were observed in groups of 56 - 60, 61 - 65, 66 - 70 and more than 70 years. With the increasing age range in four groups, the increasing trends of menstruation span were observed, which the difference of 1.41 year was shown between groups of 56 - 60 and more than 70 years. (3) The impact of menarche age on menopausal age and menstruation span: there was no correlation between menarche age and menopausal age (r = 0.02); however, menstruation span was found to be negatively correlated with the menarche age (r = -0.43). (4) The impact of parity on menopausal age and menstruation span: the mean menopausal age of women who had 1 - 2 deliveries was significantly higher than those had no delivery or more than 3 deliveries (P < 0.05). However, there was no difference in menopausal age between women with 1 and 2 deliveries or between women without delivery and more than 3 deliveries (P > 0.05). Menstruation span of women with 1 delivery was significantly longer that those with more than 1 delivery (P < 0.05), similarly, women with 2 deliveries had longer menstruation span than women without delivery or more than 3 deliveries (P < 0.05). There were no difference in menstruation span between women with more than 3 deliveries and without delivery (P > 0.05). (5) Multifactor regression analysis for menstruation span: menarche age was correlated with menstruation span negatively (r = -0.97, P < 0.001). There was significantly different menstruation span between group of 61 - 65, 66 - 70 or more than 70 years and group of 56 - 60 (r = -0.18, P = 0.020; r = -0.78, P < 0.001 and r = -1.23, P < 0.001). Menstruation span in women with 1 - 2 deliveries was significantly longer than that of women without delivery or more than 3 deliveries. (6) Multifactor logistic analysis of menopausal age: there was no association between menarche age and menopausal age, however, significant differences were found in mean menopausal age between different groups, which show that menopausal age of group 56 - 60 years was significant higher than the other groups, including age-group 61 - 65 years, 66 - 70 years and over 70 years (r = -0.18, P = 0.020; r = -0.78, P < 0.001; r = -1.23, P < 0.001). Menopausal age in women with 1 - 2 deliveries was significantly higher than those of women without delivery or with more than 3 deliveries, however, no difference between women with 1 and 2 deliveries or between women without deliveries and more than 3 deliveries was observed. (1) Menopausal age and menstruation span exhibited increasing trends in Pudong district of Shanghai. (2) Menarche age and parity were the important factors influencing menopausal age and menstruation span. (3) With younger age of menarche, the menstruation span become longer.(4) Deliveries of 1 - 2 times can significantly delay the menopause and prolong menstruation span, however, the multiple deliveries (≥ 3 times) had no significant impact on menopausal age and menstruation span.

Within the agriculturally-intensive Mississippi River Basin of the United States, significant conservation efforts have focused on management practices that reduce nutrient runoff into receiving aquatic ecosystems. Only a small fraction of those efforts have focused on phytoremediation techniques. Each of six different aquatic macrophytes were planted, in monoculture, in three replicate mesocosms (1.2 m × 0.15 m × 0.65 m). Three additional unvegetated mesocosms served as controls for a total number of 21 mesocosms. Over two years, mesocosms were amended once each summer with sodium nitrate, ammonium sulfate, and potassium phosphate dibasic to represent nitrogen and phosphorus in agricultural runoff. System retention was calculated using a simple aqueous mass balance approach. Ammonium retention in both years differed greatly, as Panicum hemitomon and Echinodorus cordifolius retentions were significantly greater than controls in the first year, while only Myriophyllum aquaticum and Typha latifolia were significantly greater than controls in the second year. Greater soluble reactive phosphorus retention was observed in T. latifolia compared to controls in both years. Several other significant differences were observed in either the first or second year, but not both years. In the first year's exposure, P. hemitomon was significantly more efficient than the control, Saururus cernuus, and T. latifolia for overall percent nitrate decrease. Results of this novel study highlight inherent variability within and among species for nutrient specific uptake and the temporal variations of species for nutrient retention. By examining this natural variability, scientists may design phytoremediation systems with greater impact on improving agricultural runoff water quality. Published by Elsevier Ltd.

The stabilization in levels of childhood overweight has masked increasing gaps among different ethnic and socioeconomic groups in several countries. To examine if levels and trends in childhood overweight and obesity differed by ethnicity and socioeconomic areas in Copenhagen schoolchildren. From measured heights and weights of 32,951 children 5-8 and 14-16 years of age, the prevalence of overweight (including obesity) and obesity were estimated using International Obesity Task Force criteria. Differences in prevalence levels and trends across six school years by ethnicity and socioeconomic areas were examined using logistic regression. The prevalence of overweight significantly decreased from 2002 to 2007 among the youngest Western girls and boys, showed no significant changes among the oldest non-Western girls and increased among the oldest non-Western boys. In all years, the youngest non-Western children had significantly higher levels of overweight than Western children. Although the prevalence of overweight tended to be higher in low socioeconomic areas as compared with high socioeconomic areas, few differences were statistically significant. Consistent trends in overweight across the years by socioeconomic area were not observed. Ethnic and social inequalities exist in childhood overweight among Copenhagen schoolchildren; thus appropriate interventions targeting high-risk groups are needed. © 2016 The Author(s) Published by S.

Research Findings: The purpose of this study was to examine differences in the development of conflict management strategies, focusing on 3- and 5-year-olds, through a comparison of 3 neighboring Asian cultures, those of China ( n = 114), Japan ( n = 98), and Korea ( n = 90). The dual concern model of conflict management was adopted to probe which strategy children would prefer to use in 2 hypothetical conflict situations. Results indicated that, first, for disagreement, 3-year-olds in the 3 countries equally preferred the dominating strategy. For competition for resources, 3-year-olds differed in their strategy preference across all cultures. Second, the observed strategy preference of 3- to 5-year-old children in this study was more or less different from that of older schoolchildren, regardless of culture. Practice or Policy: These findings suggest the significance of the context, the complexity of the phenomenon of the development of cultural differences, and the significance of cohort sampling.

Using a mixed longitudinal design, the incidence of injuries, and the development of flexibility and isometric strength of the upper and lower limbs were studied for 2 years in 453 élite young athletes (aged between 9 and 18 years) practising football, gymnastics, swimming or tennis. The children suffered from a low incidence of injuries. Strength and flexibility did not exert a significant role in determining injuries. The rate of injury was not significantly different between the 2 years of the study. Young swimmers showed a greater generalized flexibility. Girls were more flexible than boys between the ages of 13 to 16 years. Athletic children are able to exert greater isometric strength than normal schoolchildren. Boys diverged from the normal population at 14 years, while athletic girls were stronger at all ages. Girls were stronger than boys up to age 12, who were still increasing their muscle strength at 19 years. The average maximal isometric strength exerted in both upper and lower limbs in the four sports was not significantly different. Male gymnasts over 11 years old were significantly stronger than all other athletes. PMID:7921912

The aim of this study was to measure round window (RW) diameters in patients with congenital aural atresia (CAA) or sensorineural hearing loss (SNHL) and a normal control group and to analyze whether differences exist between these groups. Temporal bone computed tomographic scans of 12 patients with CAA (5 males, 7 females) aged 1 to 50 years (median age, 6 years), 12 patients with SNHL (8 males, 4 females) aged 2 to 32 years (median age, 5 years), and 11 patients (3 males, 7 females) aged 2 months to 53 years (median age, 8 years) randomly selected from a pool of patients with unilateral chronic otitis media or cholesteatoma were reviewed. We measured RW diameter on oblique reconstruction planes. To prevent possible individual differences, skull width was measured. There were no statistically significant differences between all groups for skull width. Both RW diameter and RW membrane width were found smaller in the CAA group than both SNHL group and control group with statistical significance, whereas there were no statistically significant differences between the SNHL group and the control group. We found that both the RW diameter and RW membrane width in CAA were smaller than those in the control group. If this finding is supported in future studies, the production of floating mass transducer with different sizes may be useful. We suggest that RW diameter should be measured in each patient before operation and thus a floating mass transducer with the appropriate caliber should be chosen.
Developmental and sex-related differences in preschoolers' affective decision making.

This study investigated developmental and sex-related differences in affective decision making, using a two-deck version of Children's Gambling Task administered to 3- and 4-year-old children. The main findings were that 4-year-old children displayed better decision-making performance than 3-year-olds. This effect was independent of developmental changes in inductive reasoning, language, and working memory. There were also sex differences in decision-making performance, which were apparent only in 3-year-old children and favored girls. Moreover, age predicted awareness of task and the correlation between the latter and decision-making performance was significant, but only in 4-year-old children. This study thus indicates that there is a remarkable developmental leap in affective decision making, whose effects are apparent around the age of 4, which according to our results, also marks the age when the correlation of declarative knowledge and decision-making performance becomes significant.

This study quantified differences in indirect costs due to decreased work productivity between current and former smokers. Former smokers were further categorized by number of years since quitting to assess corresponding differences. Data on employed individuals were obtained from the 2013 US National Health and Wellness Survey (NHWS; N = 75,000). Indirect costs were calculated for current smokers and former smokers from weekly wages based on age and sex. The annual total indirect costs for current smokers were $1327.53, $1560.18, and $1839.87 higher than for those who quit 0 to 4 years, 5 to 10 years, and more than or equal to 11 years prior, respectively. There were no significant differences in mean total indirect costs between the former smoker groups. Current smokers showed significantly higher total annual indirect costs compared with former smokers, independently of the number of years since quitting smoking.

To evaluate visual impairment in Usher syndrome 1b (USH1b) and Usher syndrome 2a (USH2a). We carried out a retrospective study of 19 USH1b patients and 40 USH2a patients. Cross-sectional regression analyses of the functional acuity score (FAS), functional field score (FFS) and functional vision score (FVS) related to age were performed. Statistical tests relating to regression lines and Student's t-test were used to compare between (sub)groups of patients. Parts of the available individual longitudinal data were used to obtain individual estimates of progressive deterioration and compare these to those obtained with cross-sectional analysis. Results were compared between subgroups of USH2a patients pertaining to combinations of different types of mutations. Cross-sectional analyses revealed significant deterioration of the FAS (0.7% per year), FFS (1.0% per year) and FVS (1.5% per year) with advancing age in both patient groups, without a significant difference between the USH1b and USH2a patients. Individual estimates of the deterioration rates were substantially and significantly higher than the cross-sectional estimates in some USH2a cases, including values of about 5% per year (or even higher) for the FAS (age 35-50 years), 3-4% per year for the FFS and 4-5% per year for the FVS (age > 20 years). There was no difference in functional vision score behaviour detected between subgroups of patients pertaining to different biallelic combinations of specific types of mutations. The FAS, FFS and FVS deteriorated significantly by 0.7-1.5% per year according to cross-sectional linear regression analysis in both USH1b and USH2a patients. Higher deterioration rates (3-5% per year) in any of these scores were attained, according to longitudinal data collected from individual USH2a patients. Score behaviour was similar across the patient groups and across different biallelic combinations of various types of mutations. However, more elaborate studies, preferably covering longitudinal data, are needed to obtain conclusive evidence.

The unreliability of difference scores is a well documented phenomenon in the social sciences and has led researchers and practitioners to interpret differences cautiously, if at all. In the case of the Kaufman Adult and Adolescent Intelligence Test (KAIT), the unreliability of the difference between the Fluid IQ and the Crystallized IQ is due to the high correlation between the two scales. The consequences of the lack of precision with which differences are identified are wide confidence intervals and unpowerful significance tests (i.e., large differences are required to be declared statistically significant). Reliable component analysis (RCA) was performed on the subtests of the KAIT in order to address these problems. RCA is a new data reduction technique that results in uncorrelated component scores with maximum proportions of reliable variance. Results indicate that the scores defined by RCA have discriminant and convergent validity (with respect to the equally weighted scores) and that differences between the scores, derived from a single testing session, were more reliable than differences derived from equal weighting for each age group (11-14 years, 15-34 years, 35-85+ years). This reliability advantage results in narrower confidence intervals around difference scores and smaller differences required for statistical significance.

Birds living in coastal areas are exposed to severe storms and tidal flooding during the nesting season, but also to contaminants that move up the food chain from the water column and sediment to their prey items. We examine metals in Herring Gull (Larus argentatus) and Great Black-backed Gull (Larus marinus) eggs collected from the New York/New Jersey harbor estuary in 2012 and in 2013 to determine if there were significant yearly differences in metal levels. We test the null hypothesis that there were no significant yearly differences in metal levels. We investigate whether there were consistent differences in metals from 2012 to 2013 that might suggest a storm-related effect because Superstorm Sandy landed in New Jersey in October 2012 with high winds and extensive flooding, and view this research as exploratory. Except for arsenic, there were significant inter-year variations in the mean levels for all colonies combined for Herring Gull, and for lead, mercury and selenium for Great Black-backed Gulls. All metal levels in 2013 were less than in 2012, except for lead. These differences were present for individual colonies as well. Metal levels varied significantly among islands for Herring Gulls in both years (except for cadmium in 2013). No one colony had the highest levels of all metals for Herring Gulls. A long term data set on mercury levels in Herring Gulls indicated that the differences between 2012 and 2013 were greater than usual. Several different factors could account for these differences, and these are discussed.

Background Studies have shown the importance of metacognition in medical education. Metacognitive skills consist of two dimensions: knowledge of metacognition and regulation of metacognition. Aim This study hypothesizes that the knowledge and regulation of metacognition is significantly different at the beginning and end of the academic year, and a correlation exists between the two dimensions of metacognitive skills with academic performance. Methods The Metacognitive Skills Inventory comprising 52 Likert-scale items was administered to 159 first-year medical students at the University of Malaya. Students’ year-end results were used to measure their academic performance. Results A paired sample t-test indicated no significant difference for knowledge of metacognition at the beginning and end of the academic year. A paired sample t-test revealed significant difference for regulation of metacognition at the beginning and end of the academic year. A very strong correlation was found between the two dimensions of metacognition. The correlation between knowledge and regulation of metacognition with students’ academic result was moderate. Conclusions The improvement in students’ metacognitive regulation and the moderate correlation between knowledge and regulation of metacognition with academic performance at the end of the academic year indicate the probable positive influence of the teaching and learning activities in the medical program.

To compare outcomes of the retropubic versus the transobturator tension-free vaginal tape (TVT vs TVT-O) at 5 years. A total of 569 women undergoing surgery for primary stress incontinence were randomized to receive a retropubic or a transobturator tensionfree vaginal tape (TVT or TVT-O). Follow-up at 5 years included clinical examination, urodynamic studies and quality of life. The primary outcome measure was continence defined as a negative cough stress test at a volume of 300 mL. Secondary outcomes included urodynamic parameters, complications and quality of life.ClinicalTrials.gov (NCT 0041454). Three hundred and thirty-one patients (59%) were evaluated at 5 years (277 were seen, examined and completed questionnaires; 54 only completed questionnaires). No significant differences were seen in rates of a negative cough stress test (83% vs 76%, respectively), urodynamic parameters and complications. Quality-of-life improved significantly in both groups, without significant differences between the groups. Erosion rates were 5.2% and 4.5%, and reoperation rates were 4.1% and 3.2% respectively. At 5 years, subjective and objective results after TVT and TVT-O are stable and similar, without statistical significant differences between the procedures. Major long-term problems appear rare. © 2017 Wiley Periodicals, Inc.

Differences in cognitive development have been observed across a variety of ethnic minority groups but relatively little is known about the persistence of these developmental inequalities over time or generations. A repeat cross-sectional analysis assessed cognitive ability scores of children aged 3, 5 and 7 years from the longitudinal UK Millennium Cohort Study (white UK born n=7630; Indian n=248; Pakistani n=328; Bangladeshi n=87; black Caribbean n=172; and black African n=136). Linear regression estimated ethnic differences in age normed scores at each time point. Multivariable logistic regression estimated within-group generational differences in test scores at each age adjusting stepwise for sociodemographic factors, maternal health behaviours, indicators of the home learning environment and parenting styles. The majority of ethnic minority groups scored lower than the white UK born reference group at 3 years with these differences narrowing incrementally at ages 5 and 7 years. However, the black Caribbean group scored significantly lower than the white UK born reference group throughout early childhood. At 3 years, Pakistani, black Caribbean and black African children with UK born mothers had significantly higher test scores than those with foreign born mothers after baseline adjustment for maternal age and child gender. Controlling for social, behavioural and parenting factors attenuated this generational advantage. By 7 years there were no significant generational differences in baseline models. Ethnic differences in cognitive development diminish throughout childhood for the majority of groups. Cumulative exposure to the UK environment may be associated with higher cognitive development scores. Published by the BMJ Publishing Group Limited.

Considering that anthropometric parameters are important factors in the performance of the soccer players, the aim of this study was to explore the differences in anthropometric and somatotype characteristics of Italian young soccer players. Weight, height, body mass index, and somatotype of 112 young soccer players, grouped in Giovanissimi "A" (14 years), "B" (13 years), and "C" (12 years) as well as Allievi "B" (15 years) and "A" (16 years) and "Juniores" (older than 17 years), were evaluated. Statistical analysis tests were computed at p ≤ 0.05, and an analysis of variance for each somatotype was calculated to analyze the main effects and interactions of the factors: categories, subcategories, and playing position. Bonferroni's post hoc analysis was used to identify differences among mean values. Considering all subjects, we have found significant differences in categories, subcategories, and playing position between anthropometric values and a somatotype value of 2.8-3.8-2.9. Significant differences have found among goalkeepers and the others playing position in endomorphy (p ≤ 0.001) and with defenders and midfielders in ectomorphy (p < 0.01) components, whereas no differences in mesomorphy. Analyzing the interaction between subcategories and playing position factors, a significant effect was found only in the endomorphy component (p = 0.05). The analysis of anthropometric characteristic of Italian young soccer players indicates that players have high muscularity value and low adiposity. This study showed the presence of somatotype differences for playing position within categories also in the youngest categories and subcategories, in particular, in the endomorphy component. Young soccer players should be trained with more appropriate and specific training load to avoid the increased injury risk during adolescence.

To examine gender differences in initial and long-term salary and practice ownership expectations among first-year veterinary students. Survey. First-year veterinary students at the North Carolina State University College of Veterinary Medicine during 2000 through 2003 and 2005 through 2009. A 1-page survey was distributed to students during orientation exercises or on the first day of a first-year course on ethics and jurisprudence. Students were asked to indicate their expected salary at graduation and in 5-year increments after graduation and to indicate whether they expected to own a practice after graduation. Responses were obtained from 567 female and 120 male students. There was no significant difference in initial salary expectations between male and female students. However, men had higher expectations for salary increases over the course of their career, so that expected salary was significantly higher for men than for women 5 years after graduation and beyond. A significantly greater percentage of men (69/93 [74.2%]) than women (242/499 [48.5%]) indicated they expected to own a practice. Although male and female veterinary students had similar expectations with regard to initial salaries, the male students had higher long-term salary expectations and were more likely to indicate an expectation to become a practice owner. Differences in expectations may lead to differences in behavior when those expectations are or are not met.

The current study compared longitudinal relationships between college education and patterns of heavy drinking from early adolescence to adulthood for Caucasians and African-Americans. We analyzed data from 9,988 non-Hispanic Caucasian and African-American participants from all four waves of the National Longitudinal Study of Adolescent Health. Growth curve modeling tested differences in rates of change and levels of heavy drinking from ages 13 to 31 years among non-college youth, college withdrawers, 2-year college graduates, and 4-year college graduates, and compared these differences for Caucasians and African-Americans. There were significant racial differences in relationships between college education with both changes in and levels of heavy drinking. Rates of change of heavy drinking differed significantly across the college education groups examined for Caucasians but not for African-Americans. In addition, Caucasians who graduated from 4-year colleges showed the highest levels of heavy drinking after age 20 years, although differences among the four groups diminished by the early 30s. In contrast, for African-Americans, graduates from 2- or 4-year colleges did not show higher levels of heavy drinking from ages 20 to 31 years than the non-college group. Instead, African-American participants who withdrew from college without an associate's, bachelor's, or professional degree consistently exhibited the highest levels of heavy drinking from ages 26 to 31 years. The relationship between college education and increased levels of heavy drinking in young adulthood is significant for Caucasians but not African-Americans. Conversely, African-Americans are likely to be more adversely affected than are Caucasians by college withdrawal. Copyright © 2013 Society for Adolescent Health and Medicine.

In view of the threat posed by climate change, we studied the influence of temperature, precipitation, cultivar characteristics, and technical management measures on the occurrence of phytopathogenic fungi in wheat during 2009-2013. This work involved experiments at two sites differing in average temperatures and precipitation. Temperature and precipitation appear to influence differences in the spectrum of phytopathogenic fungi at the individual sites. In 2009 (the warmest year), Alternaria triticina was dominant. In 2010 (having the smallest deviations from the average for individual years), Septoria tritici dominated. In 2011, Puccinia triticina was most prominent, while in 2012, the genus Drechslera (Pyrenophora) and in 2013, S. tritici and Drechslera tritici-repentis (DTR) dominated. Temperature and precipitation levels in the individual spring months (warmer March to May) played a large role, especially for the leaf rust P. triticina in 2011. A change of only 1 °C with different precipitation during a year played a significant role in changing wheat's fungal spectrum. Cluster analysis showed the differences between single pathogenic fungi on wheat in a single year due to temperature and precipitation. Alternaria abundance was strongly influenced by year (p < 0.001) while locality was significant only in certain years (2012, 2013; p = 0.004 and 0.015, respectively). The same factors were revealed to be significant in the case of Puccinia, but locality played a role (p < 0.001) in different years (2011, 2013). The abundance of S. tritici and Pyrenophora tritici-repentis (Drechslera tritici-repentis) was influenced only by year (p < 0.001).

Purpose: We have previously reported on the mortality, morbidity, and 5-year survival of 458 patients who underwent radical radiotherapy or surgery for invasive bladder cancer in Yorkshire from 1993 to 1996. We aim to present the 10-year outcomes of these patients and to reassess factors predicting survival. Methods and Materials: The Northern and Yorkshire Cancer Registry identified 458 patients whose cases were subjected to Kaplan-Meier all-cause survival analyses, and a retrospective casenote analysis was undertaken on 398 (87%) for univariate and multivariate Cox proportional hazards modeling. Additional proportional hazards regression modeling was used to assess the statistical significance of variablesmore » on overall survival. Results: The ratio of radiotherapy to cystectomy was 3:1. There was no significant difference in overall 10-year survival between those who underwent radiotherapy (22%) and radical cystectomy (24%). Univariate analyses suggested that female sex, performance status, hydronephrosis and clinical T stage, were associated with an inferior outcome at 10 years. Patient age, tumor grade, treatment delay, and caseload factors were not significant. Multivariate analysis models were created for 0-2 and 2-10 years after treatment. There were no significant differences in treatment for 0-2 years; however, after 2 years follow-up there was some evidence of increased survival for patients receiving surgery compared with radiotherapy (hazard ratio 0.66, 95% confidence interval: 0.44-1.01, p = 0.06). Conclusions: a 10-year minimum follow-up has rarely been reported after radical treatment for invasive bladder cancer. At 10 years, there was no statistical difference in all-cause survival between surgery and radiotherapy treatment modalities.« less

Frameworks like the CanMEDS model depicting professional roles and specific professional activities provide guidelines for postgraduate education. When medical graduates start their residency, they should possess certain competencies related to communication, management and professionalism while other competencies will be refined during postgraduate training. Our study aimed to evaluate the relevance of different competencies for a first year resident required for entrustment decision from the perspective of physicians from medical faculties with different undergraduate medical curricula. Nine hundred fifty-two surgeons and internists from three medical schools with different undergraduate medical curricula were invited to rank 25 competencies according to their relevance for first year residents. The rankings were compared between universities, specialties, physicians' positions, and gender. Two hundred two physicians participated, 76 from Hamburg University, 44 from Oldenburg University, and 82 from Technical University Munich. No significant differences were found regarding the top 10 competencies relevant for first year residents between the universities. 'Responsibility' was the competency with the highest rank overall. Internists ranked 'Structure, work planning and priorities' higher while surgeons ranked 'Verbal communication with colleagues and supervisors' higher. Consultants evaluated 'Active listening to patients' more important than department directors and residents. Female physicians ranked 'Verbal communication with colleagues and supervisors' and 'Structure, work planning and priorities' significantly higher while male physicians ranked 'Scientifically and empirically grounded method of working' significantly higher. Physicians from universities with different undergraduate curricula principally agreed on the competencies relevant for first year residents. Some differences between physicians from different positions, specialties, and gender were found. These differences should be taken into account when planning competence-based postgraduate education training programs.
Classic conditioning in aged rabbits: delay, trace, and long-delay conditioning.
Solomon, P R; Groccia-Ellison, M E

Young (0.5 years) and aged (2+, 3+, and 4+ years) rabbits underwent acquisition of the classically conditioned nictitating membrane response in a delay (500-ms conditioned stimulus [CS], 400-ms interstimulus interval [ISI]), long-delay (1,000-ms CS, 900-ms ISI), or trace (500-ms CS, 400-ms stimulus-free period) paradigm. Collapsing across age groups, there is a general tendency for animals to acquire trace conditioning more slowly than delay conditioning. Collapsing across conditioning paradigms, there is a general tendency for aged animals to acquire more slowly than younger animals. Of greater significance, however, are the age differences in the different conditioning paradigms. In the delay and long-delay paradigms, significant conditioning deficits first appeared in the 4(+)-year-old group. In the trace conditioning paradigm, significant conditioning deficits became apparent in the 2(+)-year-old animals.

To compare prosthesis and implant failure, patient satisfaction, prosthetic complications and peri-implant marginal bone loss of mandibular overdentures (IOD) supported by a single or two implants. Manual and electronic database (PubMed and Cochrane) searches were performed to identify randomised controlled trials, without language restriction, comparing single vs two implant supported mandibular overdentures. Two investigators extracted data independently. The Cochrane tool was used for assessing the quality of included studies. Meta-analyses were performed for the included RCTs. Six publications corresponding to four RCTs were identified. Three RCTs (corresponding to five publications) were included and one trial was excluded. Follow-ups in function were 1, 3 and 5 years after loading. All included studies were considered to be at a high risk of bias. The pooled result revealed more prosthesis failures at overdentures supported by two implants at 1 year (three trials) (P = 0.02; Risk Difference: -0.12, 95% CI: -0.22, -0.02), however, there were non-significant differences at 3 years (two trials) (P = 0.22; Risk Difference: -0.32, 95% CI: -0.83, 0.19) and at 5 years (one trial) (P = 0.95; Risk Difference: 0.01, 95% CI: -0.22, 0.24). Regarding implant failures, there were more implant losses in overdentures supported by two implants at 1 year (three trials) (P = 0.02; Risk Difference: -0.12, 95% CI: -0.22, -0.02) and at 5 years (one trial) (P = 0.95; Risk Difference: -0.15, 95% CI: -0.28, -0.02), however, there were non-significant difference at 3 years (two trials) (P = 0.2; Risk Difference: -0.33, 95% CI: -0.84, 0.18). After 5 years in function, meta-analyses revealed that there were non-significant differences regarding overall prosthetic complications when mandibular overdentures supported by a single implant were compared with overdentures supported by two implants (P = 0.43; RD: 0.04, 95% CI: -0.06, 0.15). Mandibular overdentures retained by a single implant have comparable results to those retained by two implants. However, this should be interpreted with caution as all the included studies were considered at a high risk of bias.

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

Background Technological advancements have led to the success of minimally invasive treatment modalities for prostate cancer such as CyberKnife and Cryotherapy. Here, we investigate patient-reported urinary function, bowel habits, and sexual function in patients following CyberKnife (CK) or Cryotherapy treatment, and compare them with active holistic surveillance (AHS) patients. Methods An IRB-approved institutional database was retrospectively reviewed for patients who underwent CK, Cryotherapy, or AHS. Quality of life (QoL) survey responses were collected every three months and the mean function scores were analyzed in yearly intervals over the 4 years post-treatment. Results 279 patients (767 survey sets) were included in the study. There was no difference among groups in urinary function scores. The CyberKnife group had significantly lower bowel habit scores in the early years following treatment (year two mean difference: −5.4, p<0.01) but returned to AHS level scores by year four. Cryotherapy patients exhibited initially lower, but not statistically significant, bowel function scores, which then improved and approached those of AHS. Both CyberKnife (year 1 mean difference: −26.7, p<0.001) and Cryotherapy groups (−35.4, p<0.001) had early lower sexual function scores relative to AHS, but then gradually improved and were not significantly different from AHS by the third year post-treatment. A history of hormonal therapy was associated with a lower sexual function scores relative to those patients who did not receive hormones in both CyberKnife (−18.45, p<0.01) and Cryotherapy patients (−14.6, p<0.05). Conclusions After initially lower bowel habits and sexual function scores, CyberKnife or Cryotherapy-treated patients had no significant difference in QoL relative to AHS patients. These results highlight the benefit of CyberKnife and Cryotherapy in the management of organ-confined prostate cancer. PMID:29217830

This study provides a controlled assessment of the psychological (and physical) effects of growth hormone treatment. Fifteen short 'normal' children (height SD score < -2) have been treated with growth hormone since the age of 7/8 years. They, together with untreated short controls and average controls (10th-90th centiles), were assessed at recruitment, after three years, and after five years. Only the treated group showed a significant height increase (SD score -2.44 to -1.21 over five years). No significant differences were found at recruitment, three years, or five years in IQ, attainment, behaviour, or self esteem. Also at five years, there were no significant differences in locus of control, self perception, or parental perceptions of competence. Both short groups displayed less satisfaction with their height than the controls (p < 0.01), though all groups were optimistic of being tall adults. The treated children were no more unrealistic over final height than the untreated children. To date, no psychological benefits of treatment have been demonstrated; but nor have there been any discernible ill effects for either the treated or the untreated children. PMID:8813867

The half-life of leu-enkephalin in the serum of infants aged under 1 year is significantly shorter than in adults. In girls leu-enkephalin half-life is significantly longer than in boys. The half-life of leu-enkephalin is different in infants on breast and formula feeding. Nine characteristics of temperament in infants of the first year of life were determined using EITQ and ITQ questionnaires. Serum leu-enkephalin half-life directly correlated with temperament characteristics (activity, perception, threshold), but not with the level psychomotor development.

There are few studies investigating the influence of the development on mental health of minorities in China. To follow up the prevalence, natural course and prognosis of schizophrenia in Jinuo people, the last group to be recognized as a 'national minority' in China, every 10 years since 1979. From 1979 to 2009, 15%-19% of Jinuo residents were evaluated by random cluster sampling and followed up every 10 years using the Chinese version of the Composite International Diagnostic Interview (CIDI) as the screening tool and the International Classification of Diseases (ICD) as diagnostic criteria tool. There were no significant differences for the lifetime prevalence and current prevalence of schizophrenia across the three decades. Neither were there any significant differences for the prognosis of schizophrenia; however, at least half the patients had deteriorated or had residual symptoms in the follow-up. PANSS symptoms were significantly different according to different illness duration. During the three decades, there was no increasing trend for schizophrenia prevalence in Jinuo society; however, the prognosis of schizophrenia was not optimistic. In the natural, untreated status, schizophrenia patients with an illness duration of more than 20 years had more serious symptoms. © The Author(s) 2013.
Community structure and quality after 10 years in two central Ohio mitigation bank wetlands.
Spieles, Douglas J; Coneybeer, Meagan; Horn, Jonathan
2006-11-01
We evaluate two 10-year-old mitigation bank wetlands in central Ohio, one created and one with restored and enhanced components, by analysis of vegetation characteristics and by comparison of the year-10 vegetation and macroinvertebrate communities with reference wetlands. To assess different measures of wetland development, we compare the prevalence of native hydrophytes with an index of floristic quality and we evaluate the predictability of these parameters in year 10, given 5 years of data. Results show that the mitigation wetlands in this study meet vegetation performance criteria of native hydrophyte establishment by year 5 and maintain these characteristics through year 10. Species richness and floristic quality, as well as vegetative similarity with reference wetlands, differ among mitigation wetlands in year 1 and also in their rate of change during the first 10 years. The prevalence of native hydrophytes is reasonably predictable by year 10, but 5 years of monitoring is not sufficient to predict future trends of floristic quality in either the created or restored wetland. By year 10, macroinvertebrate taxa richness does not statistically differ among these wetlands, but mitigation wetlands differ from reference sites by tolerance index and by trophic guild dominance. The created wetland herbivore biomass is significantly smaller than its reference, whereas detritivore biomass is significantly greater in the created wetland and smaller in the restored wetland as compared with respective reference wetlands. These analyses illustrate differences in measures of wetland performance and contrast the monitoring duration necessary for legal compliance with the duration required for development of more complex indicators of ecosystem integrity.

Objectives Few studies have examined the long-term effect of age at implantation on outcomes using multiple data points in children with cochlear implants. The goal of this study was to determine if age at implantation has a significant, lasting impact on speech perception, language, and reading performance for children with prelingual hearing loss. Design A linear mixed model framework was utilized to determine the effect of age at implantation on speech perception, language, and reading abilities in 83 children with prelingual hearing loss who received cochlear implants by age 4. The children were divided into two groups based on their age at implantation: 1) under 2 years of age and 2) between 2 and 3.9 years of age. Differences in model specified mean scores between groups were compared at annual intervals from 5 to 13 years of age for speech perception, and 7 to 11 years of age for language and reading. Results After controlling for communication mode, device configuration, and pre-operative pure-tone average, there was no significant effect of age at implantation for receptive language by 8 years of age, expressive language by 10 years of age, reading by 7 years of age. In terms of speech perception outcomes, significance varied between 7 and 13 years of age, with no significant difference in speech perception scores between groups at ages 7, 11 and 13 years. Children who utilized oral communication (OC) demonstrated significantly higher speech perception scores than children who used total communication (TC). OC users tended to have higher expressive language scores than TC users, although this did not reach significance. There was no significant difference between OC and TC users for receptive language or reading scores. Conclusions Speech perception, language, and reading performance continue to improve over time for children implanted before 4 years of age. The current results indicate that the effect of age at implantation diminishes with time, particularly for higher-order skills such as language and reading. Some children who receive CIs after the age of 2 years have the capacity to approximate the language and reading skills of their earlier-implanted peers, suggesting that additional factors may moderate the influence of age at implantation on outcomes over time.

The change characteristics of soil organic carbon and microbial function diversity in Chinese hickory Carya cathayensis stands with different intensive-management durations (5, 10, 15 and 20 years) were studied. The results showed that soil total organic carbon (TOC), microbial biomass carbon (MBC), water-soluble organic carbon (WSOC) decreased significantly, while the stability of soil C pool increased significantly after the conversion from evergreen and deciduous broadleaf forest to intensively-managed forest (IMF). TOC, MBC and WSOC in the hickory forest soil decreased by 28.4%, 34.1% and 53.3% with 5-year intensive management, and by 38.6%, 48.9% and 64.1% with 20-year intensive management, respectively. The proportions of carboxyl C, phenolic C and aromatic C in the hickory forest soil all increased significantly, and the aromaticity of soil organic C increased by 23.0%. Soil microbial functional diversity decreased greatly af- ter intensive management of Chinese hickory forest. Significant differences in average well color development (AWCD) were found between the 0- and 5-year treatments and the 10-, 15- and 20- year treatments. The microbial diversity indexes (H) and evenness indexes (E) in the 0- and 5-year treatments were much greater than in the 10- and 20-year treatments. Correlation analysis showed that there were significant correlations among soil TOC, WSOC, MBC, AWCD, H and E.

Heritability studies of BMI, based upon twin samples, have identified genetic and shared environmental components of BMI, but have been largely silent about the nonshared environmental factors. Intrauterine factors have been identified as having significant long-term effects on BMI and may be a critical source of nonshared environmental influence. Extant studies based on samples of either unrelated individuals or twins cannot separate the effects of genetics, shared environments, and nonshared intrauterine conditions because the one lacks variation in the degree of relatedness and the other has insufficient variation in intrauterine conditions. This study improves upon these prior studies by using a large, sibling-based sample to examine heritability, shared environmental, and nonshared intrauterine influences on BMI during two age periods in childhood (6-8 years; 12-14 years). The primary interest was in determining the effects of the intrauterine environment on BMI as a component of the nonshared environment and in determining whether there were sex-specific differences in heritability and/or in the intrauterine factors. These were estimated using regression-based techniques introduced by DeFries and Fulker. Heritability of BMI was estimated to be 0.20-0.28 at 6-8 years and 0.46-0.61 at 12-14 years. Differences in heritability were found at 12-14 years between same-sex as compared to mixed-sex pairs. The shared environmental effect was significant at 6-8 years but insignificant at 12-14 years. Differences in birth weight were significant in all groups at 6-8 years suggesting long-term effects of the nonshared intrauterine environment; at 12-14 years, birth weight was no longer significant for girls.

Kelly, SJ, Watsford, ML, Austin, DJ, Spurrs, RW, Pine, MJ, and Rennie, MJ. Differences in physical capacity between junior and senior Australian footballers. J Strength Cond Res 31(11): 3059-3066, 2017-The purpose of this study was to profile and compare anthropometric and physical capacities within elite junior and senior Australian football (AF) players of various chronological ages and stages of athletic development. Seventy-nine players, including junior and senior AF players from one professional club, were profiled using 11 assessments. Junior players were divided into 2 groups based on chronological age (under 16 and 18 years) and senior players according to years since drafted to a professional AF team (1-2 years, 3-7 years, and 8+ years). Parametric data were assessed using a 1-way analysis of variance (ANOVA), whereas nonparametric data were assessed using a Kruskal-Wallis ANOVA. The magnitude difference between players was measured using the Hopkins' effect size (ES). Significant differences were evident between under-16 players and all senior player groups for anthropometric (p = 0.001-0.019/ES = 1.25-2.13), absolute strength (p = 0.001-0.01/ES = 1.82-4.46), and relative strength (p = 0.001-0.027/ES = 0.84-3.55). The under-18 players displayed significantly lower absolute strength (p = 0.001-0.012/ES = 1.82-3.79) and relative strength (p = 0.001-0.027/ES = 0.85-4.00) compared with the 3-7 and 8+ players. Significant differences were evident between the under-16 players and senior player groups for explosive jumping and throwing tests (p = 0.001-0.017/ES = 1.03-2.99). Minimal differences were evident between all player groups for running assessments; however, the under-16 players were significantly slower compared with the 8+ players for the 3-km time trial (p < 0.02/ES = 1.31), whereas both junior player groups covered significantly less distance during the Yo-Yo IR2 (p < 0.02/ES = 1.19 and 1.60). Results of this study display a significant deficit in strength between junior and senior AF players.

Results showed that after 10 years annual circumference growth was still significantly related to the degree of release. The growth trend was established the first year but significant differences...
Variation in Age and Size in Fennoscandian Three-Spined Sticklebacks (Gasterosteus aculeatus)
DeFaveri, Jacquelin; Merilä, Juha
2013-01-01
Average age and maximum life span of breeding adult three-spined sticklebacks (Gasterosteus aculeatus) were determined in eight Fennoscandian localities with the aid of skeletochronology. The average age varied from 1.8 to 3.6 years, and maximum life span from three to six years depending on the locality. On average, fish from marine populations were significantly older than those from freshwater populations, but variation within habitat types was large. We also found significant differences in mean body size among different habitat types and populations, but only the population differences remained significant after accounting for variation due to age effects. These results show that generation length and longevity in three-spined sticklebacks can vary significantly from one locality to another, and that population differences in mean body size cannot be explained as a simple consequence of differences in population age structure. We also describe a nanistic population from northern Finland exhibiting long life span and small body size. PMID:24260496

To evaluate the efficacy of intravitreal aflibercept therapy using a treat-and-extend regimen on treatment-naïve pachychoroid neovasculopathy (PNV) and Type 1 neovascular age-related macular degeneration (AMD). We retrospectively studied 42 eyes with PNV and 60 eyes with Type 1 neovascular AMD. We assessed best-corrected visual acuity (BCVA), central macular thickness (CMT), central choroidal thickness (CCT), and total number of injections over 2 years. The BCVA and CMT improvements during the 2-year treatment period did not differ significantly between PNV and AMD; however, CCT decreased significantly in PNV than in AMD (P<0.05). Management of PNV required significantly fewer injections than AMD during the 2-year period (P<0.05). There were no significant differences in BCVA, CMT and CCT changes between PNV with and without polypoidal lesions (28 vs. 14 eyes) during the 2 year period. Significantly fewer injections were needed for PNV with polypoidal lesions than for PNV without (P<0.01). There were no significant differences in BCVA, CMT and CCT changes, or in the number of injections during the 2-year treatment period, between AMD with and without polypoidal lesions (30 vs. 30 eyes). Treat-and-extend regimen of intravitreal aflibercept injection may be equally effective in terms of improvement of BCVA and exudative changes both in eyes with PNV and those with Type 1 neovascular AMD requiring fewer injections for the former. Among eyes with PNV, those with polypoidal lesions needed fewer injections than those without polypoidal lesions.

Parents bereaved by infant death experience a wide range of symptomatology, including posttraumatic stress disorder (PTSD) that may persist for years after the loss. Little research has been conducted on PTSD in fathers who have lost an infant. Mothers report most symptoms to a greater extent than fathers, but not much is known about other sex differences following infant death. The present cross-sectional study examined sex differences in PTSD and sex differences in the relationship between PTSD severity and related variables. Subjects were 361 mothers and 273 fathers who had lost an infant either late in pregnancy, during birth or in the first year of life. Participants filled out questionnaires between 1.2 months and 18 years after the loss (M = 3.4 years). Mothers reported significantly more PTSD symptoms, attachment anxiety, emotion-focused coping and feeling let down, but significantly lower levels of attachment avoidance than fathers. Attachment anxiety, attachment avoidance and emotion-focused coping were significantly more strongly associated with PTSD severity in mothers than fathers, but only when examined alone. When all variables and time since the loss were examined together, there were no longer any significant moderation effects of sex. Persistent posttraumatic symptomatology exists in both mothers and fathers long after the loss. There are several sex differences in severity and correlates of PTSD, and a few moderation effects were identified for attachment and emotion-focused coping. Overall, more similarities than differences were found between mothers and fathers in the associations between PTSD and covariates. Copyright © 2014 Elsevier Inc. All rights reserved.

The aim of this study was to determine the difference in the prevalence of burnout syndrome in preclinical and clinical teaching doctors of Mostar School of Medicine in the academic year 2011/2012. Special attention was also focused on finding out the possible difference between the syndrome incidence that was correlated to gender and years of service. The main hypothesis was that the probability of burnout syndrome incidence was higher in the group of female clinical teaching doctors having more years of service. The study involved 62 people with high academic education employed at Mostar School of Medicine who were surveyed during a randomly selected consecutive 3-month period (February to May) of the academic year 2011/2012. The data were prospectively collected through a standardized questionnaire survey. The studied parameters were gender, years of work experience and the engagement in preclinical or clinical departments of the Medical School. The survey showed that 43 out of 62 (69.4%) respondents did not suffer the burnout syndrome, while moderate syndrome was recodred in 19 (30.6%) of them. No person had serious symptoms of the syndrome. The difference between the respondents who suffered the syndrome and those who did not was not statistically significant (P=0.002). Considering the gender of respondents, statistically significant differences were not confirmed (P=0.444). Considering the years of service, the highest incidence of the syndrome was found in people with more work experience (in the group of 21-25 years), but the difference between the groups was not statistically significant (P=0.271). Observing the work in preclinical and clinical departments, because of the limited number of patients we could not confirm the hypothesis. The syndrome had affected 13 (21%) clinical teaching doctors and 6 (9,7%) preclinical doctors, while the differenece between them was not statistically significant (P=0.054). Considering the results of this research, it has not been proven that the burnout syndrome occurred more frequently in doctors who were involved in clinical teaching than in doctors who tought in preclinical departments. Also, there was no difference in the appearance of the syndrome that was related to gender and years of service.

Exposure of children to passive smoking is significantly associated with respiratory morbidity. Youngest children between 0-2 years are harmed in the most significant way, while, together with the growing age a decrease is observed of prevalence of respiratory diseases and influence of passive smoking. During repeated investigations of children from European Longitudinal Study of Pregnancy and Childhood (ELSPAC) it was assessed, whether and how in the period from the birth to five years of age varied the rate of children exposed to environment filled with smoke and what were the differences in the frequency of diseases among the groups of children with different exposure level. Some selected characteristics of health were chosen from documentation provided in the 6th, 18th month and 5 years of children's age and processed in four children groups that differ in smoking behaviour of their mothers. The differences were statistically assessed in SPSS programme. In all compared age categories were children of smoking mothers more often exposed to stay in environment filled with smoke: children of middle and heavy smokers more, children of light smokers less. In all groups of smoking mothers, children were more often protected from exposure to passive smoking in the age of six months than after they reached 18 months and 5 years of age: differences were mostly statistically significant on the level of 1% of significance. Attending the kindergarten presents significant protecting factor for five years old children: they are more exposed during weekends than on week days (p < 0.001, resp. p < 0.01). Both respiratory symptomatology and morbidity were highly significantly increased in previous life periods of those children, whose mothers smoked. At the age of five, life in smoking household causes more frequent incidence of asthmatic symptomatology: wheezing and apnoe, and higher prevalence of allergies against home and pollen dust with breathlessness and wheezing as well (p < 0.05). ELSPAC study ascertained significant influence of maternal smoking on children's health in relation to passive smoking. Consequences of exposure clinically manifest themselves especially in increased incidence of respiratory and allergic morbidity.

There has been a rising interest in interarm blood pressure difference (IAD), due to its relationship with peripheral arterial disease and its possible relationship with cardiovascular disease. This study aimed to characterize hypertensive patients with a significant IAD in relation to cardiovascular risk. A total of 3699 patients (mean age, 61 ± 11 years) were prospectively enrolled in the study. Blood pressure (BP) was measured simultaneously in both arms 3 times using an automated cuff-oscillometric device. IAD was defined as the absolute difference in averaged BPs between the left and right arm, and an IAD ≥ 10 mm Hg was considered to be significant. The Framingham risk score was used to calculate the 10-year cardiovascular risk. The mean systolic IAD (sIAD) was 4.3 ± 4.1 mm Hg, and 285 (7.7%) patients showed significant sIAD. Patients with significant sIAD showed larger body mass index (P < 0.001), greater systolic BP (P = 0.050), more coronary artery disease (relative risk = 1.356, P = 0.034), and more cerebrovascular disease (relative risk = 1.521, P = 0.072). The mean 10-year cardiovascular risk was 9.3 ± 7.7%. By multiple regression, sIAD was significantly but weakly correlated with the 10-year cardiovascular risk (β = 0.135, P = 0.008). Patients with significant sIAD showed a higher prevalence of coronary artery disease, as well as an increase in 10-year cardiovascular risk. Therefore, accurate measurements of sIAD may serve as a simple and cost-effective tool for predicting cardiovascular risk in clinical settings.

Despite an increase in the number of cadaver donors and the number of overall organ transplantations, the dramatic increase in the waiting list makes it necessary to reconsider donor criteria. The authors examined whether differences could exist in the function and/or morphology of transplanted kidneys originated from marginal and ideal donors one and five years after transplantation. Kidney function and histopathologic findings were analysed and compared one and 5 years after transplantation in 97 patients having marginal donor kidneys and 178 patients who received ideal donor kidneys. Serum creatinine level was significantly higher (p = 0.0001) and estimated glomerular filtration rate was significantly lower (p = 0.003) in patients having marginal donor kidneys as compared to those with ideal donor kidneys 5 years after transplantation. Morphological changes in the transplanted kidneys such as tubulitis (p = 0.014) and interstitial inflammation (p = 0.025) were significantly more frequently present in patients with marginal donor kidneys than in those with ideal donor kidneys one year after transplantation. Despite an absence of differences in kidney function one year after kidney transplantation between patients having marginal and ideal donor kidneys, morphologic differences in the transplanted kidneys can be detected between the two groups of patients.

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

The World Health Organization (WHO) recommends one single dose of the Yellow Fever (YF) vaccine based on studies of antibody persistency in healthy adults. We assessed the prevalence and titers of YF virus neutralizing antibodies in previously vaccinated persons aged 60 years, in comparison to younger adults. We also evaluated the correlation between antibody titers and the time since vaccination among participants who received one vaccine dose, and the seropositivity among participants vaccinated prior to or within the past 10 years. previously vaccinated healthy persons aged 18 years were included. YF virus neutralizing antibody titers were determined by means of the 50% Plaque Reduction Neutralization Test. 46 persons aged 60 years and 48 persons aged 18 to 59 years were enrolled. There was no significant difference in the prevalence of YF virus neutralizing antibodies between the two groups (p = 0.263). However, titers were significantly lower in the elderly (p = 0.022). There was no correlation between YF virus neutralizing antibody titers and the time since vaccination. There was no significant difference in seropositivity among participants vaccinated prior to or within the past 10 years. the clinical relevance of the observed difference in YF virus neutralizing antibody titers between the two groups is not clear.

A questionnaire containing 18 vignettes of common clinical educational situations with potentially abusive treatment of medical students and a 10-item attitude assessment about abusive behaviour were administered to the first- and fourth-year medical students at a mid-west US university medical school. The first- and fourth-year groups did not differ significantly on perceived abusiveness of most of the vignettes, although several of the individual vignettes were perceived significantly differently by the two groups. As hypothesized, the fourth-year students had experienced such situations more frequently. Attitudes towards abusive behaviour did not differ between the two groups. The authors contrast teaching interactions perceived as educationally useful and not abusive with those seen as abusive and not useful and offer explanations for the differences observed. Finally, the possible implications of the results for medical education are discussed.

To determine surgical and prosthodontic outcomes of mandibular single-implant overdentures, opposing complete maxillary dentures, using a wide diameter implant and large ball attachment system compared with different regular diameter implants with standard attachment systems. Thirty-six edentulous participants (mean age 68 years, SD 9.2) were randomly assigned into three treatment groups (n=12). A single implant was placed in the mandibular midline of participants to support an overdenture using a 6-week loading protocol. The control group received Southern regular implants and standard ball attachments. One group received Southern 8-mm-wide implants and large ball attachments. Another group received Neoss regular implants and Locator attachments. Parametric and non-parametric tests of a statistical software package (SPSS) were used to determine between groups differences in marginal bone loss, implant stability, implant, and prosthodontic success (P<0.05). Implant success after 1 year was 75% for Southern regular implant (control) group; and 100% for the Southern wide and Neoss regular implant groups (P=0.038). Mean marginal bone loss at 1 year was 0.19 mm (SD 0.39) without significant differences observed. Implant stability quotient (ISQ) at baseline was significantly lower for the Southern regular (control) group than the other two groups (P=0.001; P=0.009). At 1 year, no significant difference in implant stability was observed (mean ISQ 74.6, SD 6.1). The change in implant stability from baseline to 1 year was significant for the control group (P=0.025). Prosthodontic success was comparable between the groups but the maintenance (41 events overall, mean 1.2) was greater for the Locator and the standard ball attachments. Mandibular single-implant overdentures are a successful treatment option for older edentulous adults with early loading protocol using implants of different diameters and with different attachment systems. © 2010 John Wiley & Sons A/S.

Following the Prestige oil spill, six-monthly samplings (spring and autumn) of intertidal macroalgal assemblages were carried out from 2004 to 2006 in twelve locations along the Basque coast. Macroalgal species appeared to be little modified, but species richness, diversity, and algal cover were significantly lower in the first year of the study, so it cannot be ruled out that the arrival of oil on the Basque coast might have had a damaging effect on intertidal communities. On the other hand, no significant differences were detected between locations slightly and moderately affected by oil in any of the structural parameters considered. By contrast, significant differences were detected between locations within each oiling level that indicate that other natural environmental factors play a greater role in the differences between locations than the oiling level. Likewise, significant differences were detected between areas within each location which were not consistent with time, indicating that communities are highly heterogeneous in species richness, diversity and algal cover at the scale of tens of meters. The dominant Corallina elongata and most of the accompanying species did not show significant year-on-year differences in terms of cover. Also, there were no differences between the two oiling levels. Analyses revealed a high spatial variability at the scale of kilometers (locations) and tens of meters (areas) for most of the taxa. The results obtained provide detailed quantitative data on intertidal phytobenthic assemblages of the Basque coast at different spatial and temporal scales that were hitherto unavailable for the region.

To study the connection between parental myopia and their children's myopia from school age to adulthood. Two hundred and forty myopic schoolchildren (119 boys, 121 girls, mean age 10.9 years) with no previous spectacles for myopia were recruited to a 3-year treatment trial with different use of spectacles. Follow-ups were performed at mean ages of 13.9, 23.7 and 33.2 years for 238, 176 and 170 subjects respectively. Subjective refraction was calibrated to the spherical equivalent at corneal level (SEcor). Corneal refractive power (CR) and axial length (AL) were measured. Parental myopia was assessed with a questionnaire and the children assigned accordingly to one of three hereditary groups: both parents myopic H++, one myopic parent = H+- and no myopic parents = H-. At baseline, no significant gender differences in age or SEcor were found in the different hereditary groups. Among girls, CR was significantly higher in hereditary group H++ (45.20 ± 1.08 D) than in group H+- (44.19 ± 1.28 D; p = 0.006) or H- (43.84 ± 1.18 D; p < 0.001). Among boys, the differences in CR between the hereditary groups were smaller and significant at follow-up 2 only. At follow-up end, among males, no significant differences between the hereditary groups were found in SEcor, CR, AL or myopic progression. Among females, myopic progression was 4.21 ± 1.81 D if one or both parents were myopic and -3.19 ± 1.36 D if neither parent was myopic (p = 0.035), but no significant difference was observed in AL. The main difference between the hereditary groups was higher CR and myopic progression among females with myopic parents than non-myopic parents, but with no significant difference in AL with respect to parental myopia at study end. © 2016 Acta Ophthalmologica Scandinavica Foundation.

The impact of race/ethnicity upon facial anthropometric data in the US workforce, on the development of personal protective equipment, has not been investigated to any significant degree. The proliferation of minority populations in the US workforce has increased the need to investigate differences in facial dimensions among these workers. The objective of this study was to determine the face shape and size differences among race and age groups from the National Institute for Occupational Safety and Health survey of 3997 US civilian workers. Survey participants were divided into two gender groups, four racial/ethnic groups, and three age groups. Measurements of height, weight, neck circumference, and 18 facial dimensions were collected using traditional anthropometric techniques. A multivariate analysis of the data was performed using Principal Component Analysis. An exploratory analysis to determine the effect of different demographic factors had on anthropometric features was assessed via a linear model. The 21 anthropometric measurements, body mass index, and the first and second principal component scores were dependent variables, while gender, ethnicity, age, occupation, weight, and height served as independent variables. Gender significantly contributes to size for 19 of 24 dependent variables. African-Americans have statistically shorter, wider, and shallower noses than Caucasians. Hispanic workers have 14 facial features that are significantly larger than Caucasians, while their nose protrusion, height, and head length are significantly shorter. The other ethnic group was composed primarily of Asian subjects and has statistically different dimensions from Caucasians for 16 anthropometric values. Nineteen anthropometric values for subjects at least 45 years of age are statistically different from those measured for subjects between 18 and 29 years of age. Workers employed in manufacturing, fire fighting, healthcare, law enforcement, and other occupational groups have facial features that differ significantly than those in construction. Statistically significant differences in facial anthropometric dimensions (P < 0.05) were noted between males and females, all racial/ethnic groups, and the subjects who were at least 45 years old when compared to workers between 18 and 29 years of age. These findings could be important to the design and manufacture of respirators, as well as employers responsible for supplying respiratory protective equipment to their employees.

Taking the seedlings of typical subtropical economic tree species Myrica rubra in Zhejiang Province as test materials, a pot experiment was conducted to study their water physiological characteristics under effects of simulated acid rain (pH 2.5 and pH 4.0), with water (pH 5.6) as the control. Season, year, and acid rain all had significant effects on the photosynthetic rate (Pn). Among the treatments, the Pn had a greater difference in summer than in spring and autumn, and was higher in treatment acid rain (pH 4.0). Season, year, acid rain, and the interactions of season and year and of the three factors had significant effects on the stomata conductance (Gs), and also, the Gs had a greater difference among the treatments in summer than in spring and autumn. Acid rain had inhibitory effect on Gs. Season, year, acid rain, and the interactions of season and year and of season and acid rain affected the transpiration rate (Tr) significantly. Same as Pn and Gs, the Tr had a greater difference among the treatments in summer than in spring and autumn. Acid rain (pH 2.5) had the strongest inhibitory effect on Tr. Acid rain and the interactions of season and year and of season and acid rain had significant effects on the water use efficiency (WUE), and acid rain (pH 2.5) had definitely positive effect on the WUE.

At Wayne State University School of Medicine (WSU SOM), the Robert R. Frank Student Run Free Clinic (SRFC) is one place preclinical students can gain clinical experience. There have been no published studies to date measuring the impact of student-run free clinic (SRFC) volunteerism on clinical skills development in preclinical medical students. Surveys were given to first year medical students at WSU SOM at the beginning and end of Year 1 to assess perception of clinical skills, including self-confidence, self-reflection, and professionalism. Scores of the Year 1 Objective Structured Clinical Exam (OSCE) were compared between SRFC volunteers and non-volunteers. There were a total of 206 (68.2%) and 80 (26.5%) survey responses at the beginning and end of Year 1, respectively. Of the 80 students, 31 (38.7%) volunteered at SRFC during Year 1. Statistically significant differences were found between time points in self-confidence (p < 0.001) in both groups. When looking at self-confidence in skills pertaining to SRFC, the difference between groups was statistically significant (p = 0.032) at both time points. A total of 302 students participated in the Year 1 OSCE, 27 (9%) of which were SRFC volunteers. No statistically significant differences were found between groups for mean score (p = 0.888) and established level of rapport (p = 0.394). While this study indicated no significant differences in clinical skills in students who volunteer at the SRFC, it is a first step in attempting to measure clinical skill development outside of the structured medical school setting. The findings lend themselves to development of research designs, clinical surveys, and future studies to measure the impact of clinical volunteer opportunities on clinical skills development in future physicians.

BACKGROUND Childhood leukemia incidence and survival varies globally, and this variation may be attributed to environmental risk factors, genetics, and/or disparities in diagnosis and treatment. PROCEDURE We analyzed childhood leukemia incidence and survival trends in children age 0–19 years from 1990 to 2011 in Songkhla, Thailand (n=316) and compared these results to US data from the Surveillance, Epidemiology, and End Results (SEER) registry (n=6,738). We computed relative survival using Ederer II and estimated survival functions using the Kaplan-Meier method. Changes in incidence and five-year survival by year of diagnosis were evaluated using joinpoint regression and are reported as annual percent changes (APC). RESULTS The age-standardized incidence of leukemia was 3.2 and 4.1 cases per 100,000 in Songkhla and SEER-9, respectively. In Songkhla, incidence from 1990–2011 significantly increased for leukemia (APC=1.7%, p=0.031) and acute lymphoblastic leukemia (ALL) (APC=1.8%, p=0.033). Acute myeloid leukemia (AML) incidence significantly increased (APC=4.2%, p=0.044) and was significantly different from the US (p=0.026), where incidence was stable during the same period (APC=0.3%, p=0.541). The overall five-year relative survival for leukemia was lower than that reported in the US (43% vs. 79%). Five-year survival significantly improved by at least 2% per year from 1990–2011 in Songkhla for leukemia, ALL, and AML (p<0.050). CONCLUSIONS While leukemia and ALL incidence increased in Songkhla, differences in leukemia trends, particularly AML incidence, may suggest etiologic or diagnostic differences between Songkhla and the US. This work highlights the importance of evaluating childhood cancer trends in low- and middle-income countries. PMID:25962869

We sought to investigate social differences in Swedish infant mortality by cause of death. All live single births in Sweden between 1983 and 1986 to mothers 15 to 44 years old with Nordic citizenship were studied. The causes of death were classified into six major groups. Mother's education was used as a social indicator. Logistic regression analysis was used with identical models for all groups of causes of death. There were 355,601 births and 2012 infant deaths. Only for sudden infant death syndrome were significant social differences found, with crude odds ratios of 2.6 for mothers with less than 10 years of education and of 1.9 for mothers with 10 to 11 years, compared with 1.0 for mothers with 15 years or more. After adjusting for age, parity, and smoking habits, these ratios were no longer significant. The social differences obtained could be explained by the fact that mothers with less education smoke more, are younger, and have higher parity than those with more education.

Background Communication is important for the quality of clinical practice, and programs have been implemented to improve healthcare providers’ communication skills. However, the consistency of programs teaching communication skills has received little attention, and debate exists about the application of acquired skills to real patients. This study inspects whether (1) results from a communication program are replicated with different samples, and (2) results with standardized patients apply to interviews with real patients. Methods A structured, nine-month communication program was applied in two consecutive years to two different samples of healthcare professionals (25 in the first year, 20 in the second year). Results were assessed at four different points in time, each year, regarding participants’ confidence levels (self-rated), basic communication skills in interviews with standardized patients, and basic communication skills in interviews with real patients. Data were analyzed using GLM Repeated-Measures procedures. Results Improvements were statistically significant in both years in all measures except in simulated patients’ assessment of the 2008 group. Differences between the two samples were non-significant. Differences between interviews with standardized and with real patients were also non-significant. Conclusions The program’s positive outcomes were replicated in different samples, and acquired skills were successfully applied to real-patient interviews. This reinforces this type of program structure as a valuable training tool, with results translating into real situations. It also adds to the reliability of the assessment instruments employed, though these may need adaptation in the case of real patients. PMID:24886341

Objectives: The aim of this prospective registry-based population study was to investigate the efficacy of extralevator abdominoperineal excision (ELAPE) regarding local recurrence rates within 3 years after surgery. Background: Local recurrence of rectal cancer is more common after abdominoperineal excision (APE) than after anterior resection. Extralevator abdominoperineal excision was introduced to address this problem. No large-scale studies with long-term oncological outcomes have been published. Methods: All Swedish patients operated on with an APE and registered in the Swedish ColoRectal Cancer Registry 2007 to 2009 were included (n = 1397) and analyzed with emphasis on the perineal part of the operation. Local recurrence at 3 years was collected from the registry. Results: The local recurrence rates at 3 years [median follow-up, 3.43 years (APE, 3.37 years; ELAPE, 3.41 years; not stated: 3.43 years)] were significantly higher for ELAPE compared with APE (relative risk, 4.91). Perioperative perforation was also associated with an increased risk of local recurrence (relative risk, 3.62). There was no difference in 3-year overall survival between APE and ELAPE. In the subgroup of patients with very low tumors (≤4 cm from the anal verge), no significant difference in the local recurrence rate could be observed. Conclusions: Extralevator abdominoperineal excision results in a significantly increased 3-year local recurrence rate as compared with standard APE. Intraoperative perforation seems to be an important risk factor for local recurrence. In addition to significantly increased 3-year local recurrence rates, the significantly increased incidence of wound complications leads to the conclusion that ELAPE should only be considered in selected patients at risk of intraoperative perforation.

Using molecular-genetic techniques, we determined the gender of 202 Southwestern Willow Flycatcher (Empidonax traillii extimus) nestlings from 95 nests sampled over a five-year period. Overall nestling sex ratio did not vary significantly from 50:50 among years, by clutch order, or by mating strategy (monogamous vs. polygamous pairings). However, we did observe significant differences among the four sites sampled, with sex ratios biased either toward males or females at the different sites. Given the small population sizes and geographic isolation of many of the endangered subspecies' breeding populations, sex-ratio differences may have localized negative impacts. ??

The purpose of this prospective study was to compare the efficacy of Oraqix to benzocaine while placing a rubber dam clamp during sealant placement on children. A sample size of 45 7- to 12-year-old patients who presented for bilateral sealants on permanent first molars participated in this study. A split-mouth design was implemented with Oraqix applied to one side and 20 percent benzocaine gel applied to the other. After placing the topical anesthetic and the rubber dam clamp, patients completed a Feces Pain Scale (FPS) to rate the level of discomfort after clamp placement. Twenty-seven subjects (60%) were female and 18 subjects (40%) were mole; 15 (33%) were younger than 9 years old and 30 (67%) were at least 9 years old. The overall difference in mean FPS ratings was not statistically significant (P = .27). Regarding gender, there was no statistically significant difference in males (P = .65) or females (P = .26). There was also no difference in mean FPS ratings when looking at age groups younger than 9 years old with P=.77 In the 9 years and older age groups, however there was a statistically significant difference, with P = .04. Application of Oraqix did not reduce discomfort when compared to benzocaine in this small sample size. Oraqix was more effective than benzocaine in the age group 9 and older. A larger sample size is needed to determine its efficacy in children younger than 9years old.

In some European countries there is an increasing interest on donkey. Despite there are few data regarding the donkey's parasitic diseases especially those with a protozoal etiology as neosporosis. Samples used in the study were collected from 238 domestic donkeys during year 2010 in Southern Italy from 207 females and 31 males of five breeds (Martina-Franca, Amiata, Sicilian-Grey, Ragusano, Sardinian) and crossbreeds with the average age 9 years (1 month - 24 year). Sera were tested by a competitive-inhibition enzyme-linked immunosorbent assay for antibodies against Neospora caninum; the sera were marked positive, if more than 30% inhibition was found. Out of a total 238 donkeys, 28 (11.8%) were found positive for Neospora antibodies with 12% in females and 6% in males. Different seroprevalence 15.4%, 16%, 12% and 8.8% were found in age categories <1 year, 1-4 years, 5-9 years and ≥10 years, respectively. The seroprevalence ranged in different breeds from 36% (Sicilian-Grey) to 0% (Sardinian) and in different use from 17% (for breeding) to 0% (for meat production). Logistic regression analysis demonstrated evidence of a significant (P<0.05) association between crossbreed origin of samples and risk of protozoan infection; age of donkeys was also significant risk factor for protozoan infection. No statistical significant difference (P>0.05) was found among genders and use of donkeys and risk of N. caninum infection. This is the first serological survey for Neospora spp. performed in donkeys. Copyright © 2013 Elsevier B.V. All rights reserved.

Sarcopenia, the age related decline in skeletal muscle mass has dramatic consequences. It leads to impaired performance, increased vulnerability, frailty and an increased risk of falls. Various extrinsic and intrinsic factors contribute to the aetiology of sarcopenia. The aims of the present study was to analyse gender differences in the prevalence of sarcopenia and document gender differences in lean soft tissue mass in healthy elderly. 139 healthy subjects ageing between 59 and 92 years (x = 71.5 +/- 7.8), 77 females and 64 males, were enrolled in the study. Body composition was measured by means of dual energy X-ray absorptiometry. Additionally appendicular muscle mass (ASM) was calculated. While no linear decrease in lean soft tissue mass was found for both sexes, the prevalence of sarcopenia increased significantly with increasing age in females as well as in males. Significant gender differences in the prevalence of sarcopenia were found for people younger than 70 years and those older than 80 years. In the youngest age group (< 70 years) sarcopenia was found more frequently among women, while in the oldest age group (> 80 years) the opposite was true. It can be concluded that the prevalence of sarcopenia differs between the two genders however these differences are influenced by age.

Objective To describe first-year college student-athletes’ friendship contexts and test whether their perceptions of alcohol use and approval by different types of friends are associated with their own alcohol use. Participants First-year student-athletes (N=2,622) from 47 colleges and universities participating in National Collegiate Athletic Association (NCAA) sports during February–March 2013. Methods Student-athletes completed online surveys during the baseline assessment of an alcohol and other drug prevention program evaluation. Analyses tested whether perceptions of friends’ alcohol use (descriptive norms) and perceptions of friends’ approval of alcohol use (injunctive norms) predicted their alcohol use. Results Both use and approval perceptions by upperclassmen, same-team, and most influential friends significantly predicted alcohol use. By contrast, only perceived use by first-year, non-team, and less influential friends significantly predicted alcohol use. Conclusions Athletics departments’ alcohol policies and prevention programming for first-year student-athletes should address the potential influence of different types of friends on alcohol use.

Aim: The present study was conducted to investigate the effect of species, breed and age on bacterial load in fresh and frozen semen of Cattle and Buffalo bull. Materials and Methods: Present study covered 56 cow and 10 buffalo bulls stationed at Central Semen Station Anjora, Durg (Chhattisgarh). Impact of breeds on bacterial load in semen was assessed using six breeds of cattle viz. Sahiwal, Gir, Red Sindhi, Tharparkar, Jersey and Holstein Friesian (HF) cross. Cow bulls were categorized into four different groups based on their age (<4 years, 4-5 years, 5-6 years and > 6 years) to study variation among age groups. Bacterial load was measured in fresh and frozen semen samples from these bulls using the standard plate count (SPC) method and count was expressed as colony forming unit (CFU) per ml of semen. Results: Higher bacterial load was reported in fresh (2.36 × 104 ± 1943 CFU/ml) and frozen (1.00 × 10 ± 90 CFU/ml) semen of cow bulls as compared to buffalo bulls (1.95 × 104 ± 2882 and 7.75 × 102 ± 160 CFU/ml in fresh and frozen semen, respectively). Jersey bull showed significantly higher bacterial count (p < 0.05) both in fresh (4.07 × 104 ± 13927 CFU/ml) and frozen (1.92 × 103 ± 178 CFU/ml) semen followed by HF cross, Sahiwal, Gir, Red Sindhi and Tharparkar bull. Bulls aged < 4 years and more than 6 years yielded increased bacterial load in their semen. Although a minor variation was reported between species and among age groups, no significant differences were measured. Conclusion: Bacterial load in semen did not differ significantly between species and age groups; however significant variation was reported among different breeds. Bulls of Jersey breed showed significantly higher bacterial load in semen as compared to the crossbred and indigenous bull. PMID:27047115

Objectives The aim of this study was to investigate changes in body mass index (BMI) between different work schedules and different average number of yearly night shifts over a four-year follow-up period. Methods A prospective study of Norwegian nurses (N=2965) with different work schedules was conducted: day only, two-shift rotation (day and evening shifts), three-shift rotation (day, evening and night shifts), night only, those who changed towards night shifts, and those who changed away from schedules containing night shifts. Paired student's t-tests were used to evaluate within subgroup changes in BMI. Multiple linear regression analysis was used to evaluate between groups effects on BMI when adjusting for BMI at baseline, sex, age, marital status, children living at home, and years since graduation. The same regression model was used to evaluate the effect of average number of yearly night shifts on BMI change. Results We found that night workers [mean difference (MD) 1.30 (95% CI 0.70-1.90)], two shift workers [MD 0.48 (95% CI 0.20-0.75)], three shift workers [MD 0.46 (95% CI 0.30-0.62)], and those who changed work schedule away from [MD 0.57 (95% CI 0.17-0.84)] or towards night work [MD 0.63 (95% CI 0.20-1.05)] all had significant BMI gain (P<0.01) during the follow-up period. However, day workers had a non-significant BMI gain. Using adjusted multiple linear regressions, we found that night workers had significantly larger BMI gain compared to day workers [B=0.89 (95% CI 0.06-1.72), P<0.05]. We did not find any significant association between average number of yearly night shifts and BMI change using our multiple linear regression model. Conclusions After adjusting for possible confounders, we found that BMI increased significantly more among night workers compared to day workers.

Survival rate of breast cancer patients has improved significantly in recent years. Cancer diagnosis represents a great psychological distress for patients which may not stem solely from the disease itself. Patients may experience higher distress even several years after treatment. The study was carried out at the Department of Obstetrics and Gynecology and Department of Internal Medicine, Haematology and Oncology, Faculty Hospital Brno. Results of 85 patients at 4.5 years after diagnosis of breast cancer compared to 72 healthy controls are presented in this paper. The data were collected in the form of semi-structured interviews, from the patients medical records and by Symp-tom Check List-90. The overall rate of psychological distress (GSI) 4.5 years after breast cancer dia-gnosis does not differ significantly (p = 0.703) from the healthy population. Also, we did not find any statistically significant relationship between the observed factors and the level of psychological distress in breast cancer patients. Screening investigation showed no difference in the psychological distress in breast cancer patients 4.5 years following diagnosis, compared with the healthy population.

Distinguishing an obesity growth pattern that originates during infancy is clinically important. Infancy based obesity prevention interventions may be needed while precursors of later health are forming. Infant obesity and severe obesity growth patterns in the first 2-years are described and distinguished from a normal weight growth pattern. A retrospective chart review was conducted. Body mass index (BMI) growth patterns from birth to 2-years are described for children categorized at 5-years as normal weight (n = 61), overweight (n = 47), obese (n = 41) and severely obese (n = 72) cohorts using WHO reference standards. BMI values were calculated at birth, 1-week; 2-, 4-, 6-, 9-, 12-, 15-, 18-months; and 2- and 5-years. Graphs of the longitudinal Analysis of Variance of Means of BMI values identified the earliest significant divergence of a cohort's average BMI pattern from other cohorts' patterns. ANOVA and Pearson Product Moment correlations were also performed. Statistically significant differences in BMI values and differences in growth patterns between cohorts were evident as early as 2-6 months post-birth. Children who were obese or severely obese at 5-years demonstrated a BMI pattern that differed within the first 2-years of life from that of children who were normal weight at 5-years. The earliest significant correlation between early BMI values and 5-year BMI value was at 4-months post-birth. The study fills an important gap by demonstrating early onset of an infant obesity growth pattern in full-term children who were healthy throughout their first 5 years of life.

Aims: To evaluate children referred for defecation disorders using the child behavioural checklist (CBCL). Methods: A total of 215 patients were divided into three groups: 135 (5–14 years of age) with paediatric constipation (PC), 56 (5–17 years) with functional non-retentive faecal soiling (FNRFS), and 24 (5–16 years) with recurrent abdominal pain (RAP). Behavioural scores were correlated with colonic transit time (CTT) and anorectal function parameters (manometry and EMG). Results: No significant differences in the mean CBCL scores were found among the three patient groups. However, children with PC and FNRFS had significantly more behavioural problems than the Dutch normative sample, while children with RAP had scores within the normal range. No significant differences were found between CTT in the patient groups, with respect to the CBCL. Similarly, no significant difference existed between children able or unable to relax their pelvic floor muscles during defecation attempts and their behaviour profiles. Conclusion: There seems to be no relation between colonic/anorectal function and specific behavioural profiles. On the other hand, children with defecation disorders show more behavioural problems than do controls. PMID:14709493

To study the reference ranges of six sex hormones, i.e., luteinizing hormone, follicle-stimulating hormone, progesterone, prolactin, estradiol, and testosterone, for healthy children aged 0-18 years in Shenzhen, China. Stratified cluster sampling was performed to select 2 178 healthy children aged 0-18 years in the districts of Futian, Luohu, Nanshan, Bao'an, and Longgang in Shenzhen between September 2015 and September 2016. There were 1 219 boys and 959 girls, including 81 neonates, 335 infants, 346 young children, 469 preschool children, 419 school-aged children, and 528 adolescents. The American Beckman DXI800 chemiluminescence meter was used to measure the levels of luteinizing hormone, follicle-stimulating hormone, progesterone, prolactin, estradiol, and testosterone. There were significant differences in the levels of luteinizing hormone, follicle-stimulating hormone, progesterone, prolactin, estradiol, and testosterone between different age groups (P<0.05). There were also significant differences in the levels of these sex hormones between boys and girls in the same age group (P<0.05). The reference ranges of six sex hormones were established for healthy children aged 0-18 years in Shenzhen based on the levels of these hormones in different age groups. There are significant differences in sex hormones between different age groups or sex groups. The reference ranges of six sex hormones established for different sexes or ages have great significance in the diagnosis and treatment of endocrine diseases in children.

It is theorized that intranasal cavity volumes change throughout the aging process, possibly secondary to hormonal changes and atrophy of the sinonasal mucosa. Our objective is to compare intranasal volumes from different age groups to test the hypothesis that intranasal cavity volume increases with age. Case series. An analysis of computed tomography (CT) scans performed for reasons other than sinonasal complaints. Intranasal volumes of three groups (age 20-30 years, 40-50 years, and 70 years and above) were calculated using Vitrea software. The total intranasal volume was measured from the nasal vestibule anteriorly, the nasopharynx posteriorly, the olfactory cleft superiorly, and the nasal floor inferiorly. The total volume included the sum of the right and left sides. Sixty-two CT scans were analyzed. There was a progressive, relatively linear, increase in intranasal volume with increasing age: 20 to 30 years = 15.73 mL, 40 to 50 years = 17.30 mL, and 70 years and above = 18.38 mL. Mean intranasal volume for males was 19.07 mL, and for females was 15.23 mL. Analysis of variance demonstrated significant group differences in mean intranasal volume for age (P = .003) and gender (P < .001), with moderate-to-large effect size of 0.206 and 0.289 (partial η(2) ), respectively. Post hoc testing revealed a significant difference between the 20 to 30-year and >70-year age groups (P = .006). There was no significant difference in intranasal volume dependent upon body mass index. Intranasal volume increases with age and is larger in males. Specific etiologies responsible for increased intranasal cavity volume with age are actively being evaluated. 4 Laryngoscope, 126:2212-2215, 2016. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.
[Gender differences in alcoholism].
Avila Escribano, José Juan; González Parra, David
2007-01-01
Recent epidemiological studies indicate that alcohol consumption in women has increased in the last few years, which suggests that alcoholism in women will also increase in the near future. Moreover, this disease shows differential characteristics in women, and knowledge of these characteristics is important so that treatment can begin as early as possible. The objective of the present study was to explore clinical differences in alcohol use disorders according to patients' gender. It was carried out with a sample of 370 patients, 325 men (87.8%) and 45 women (12.2%), with mean ages of 42.83 and 44.6 years, respectively. The patients were assessed through the Europasi interview and analytical studies with liver enzyme profiles and blood tests. The most notable results were: women began alcohol consumption significantly later than men (19.61 and 16.9 years, respectively; p < 0.008); they were significantly older than men when the consumption pattern became problematic (30.93 and 24.68 years, respectively; p < 0.003); they had been drinking for fewer years (13.26 versus 17.85 years; p < 0.02); and they drank fewer grams of alcohol (117.7 and 133.8 g., respectively; n.s.). Women scored significantly higher than men on the Europasi psychiatric scale (2.91 and 1.97, respectively; p < 0.007) and men had more legal problems than women (1.2 and 1.0, respectively; p < 0.000). In the biological tests the GGT enzyme values were higher in men (137.51) than in women (96.7), but this difference was not significant, and the VCM value was significantly higher for women (98.1) than for men (95.05). Another important finding was that the percentage of women who had sought private professional help was higher than that of men (15% versus 4.6%; p < 0.01).

Interposition arthroplasty with bioreplaceable poly-L-D-lactic acid (PLDLA) implants has yielded promising results in reconstruction of rheumatoid hands. In this prospective clinical study we compared the PLDLA implant arthroplasty (n = 17) with that of tendon interposition (n = 12) for destruction of the trapeziometacarpal joint in arthritic patients. There was no significant difference between the two groups preoperatively. At one-year follow-up, the mean pain and function scores were 5 and 13 in the PLDLA group, and 19 and 43 in the tendon interposition group, respectively. At one-year follow-up the visual analogue scale (VAS) for function of the PLDLA group differed significantly from that of the tendon interposition group (p = 0.03). This difference was not found at three months postoperatively, and disappeared again at two-year follow-up. Otherwise, no significant difference was found between the groups in the pain or function scores, functional tests, or range of movement. Bioreplaceable interposition arthroplasty works at least as well as tendon interposition. The operation is easier.
Fundamental movement skills and weight status in British primary school children.
Bryant, Elizabeth S; Duncan, Michael J; Birch, Samantha L
2014-01-01
Weight status has been shown to have a negative impact on children's competence in performing fundamental movement skills (FMSs). Following ethics approval and informed consent, 281 children in years 2-6 from a school in central England volunteered to participate. Each child performed eight FMSs (run, hop, gallop, jump, balance, kick, throw and catch) three times, all attempts were video-recorded. Video analysis was performed (Quintic Biomechanics software) using the Process Orient Checklist (subjective measurement). Height and weight were measured to calculate body mass index (BMI) and weight status was determined. Results highlighted that year group (age) had a significant effect on seven out of the eight skills (not kick). Year 4 (aged 8-9 years) significantly scored lower in all three locomotor skills (run, hop and gallop) at this age, whereas Year 5 (aged 9-10 years) all significantly peaked at the object control skills (catch and throw) at this age. Weight status (BMI) significantly affected the run, identifying that a child with a larger BMI will have a lower mastery level of the run. Gender significantly affected the kick, throw and balance, with girls outperforming in the balance and the boys in the kick and throw. By highlighting that children at different ages will have a lower score in different skills, the effect of BMI and gender on certain FMS is important knowledge for the target of intervention in primary school children.

The authors aimed to determine if first-professional-year pharmacy students retain library literature search skills throughout the school year. Students (n = 61 consented) were given an identical seven-item quiz on basic library search skills prior to library instruction in the fall semester and at the end of the spring semester. There was no significant difference between median scores on the two quizzes, nor were any significant differences noted in subgroup analyses. Search competency may be retained to a higher degree if library instruction is moved later in the pharmacy curriculum when literature search skills are used more often.

The effects of age and speed on foot and ankle kinematics in gait studies using foot models are not fully understood, whereas this can have significant influence. We analyzed these variables with the 4-segment Oxford foot model. Twenty-one healthy subjects (aged 20-65 years) were recruited for gait analysis. The effect of speed on foot and ankle kinematics was assessed by comparing results during slow walking and fast walking. To assess the effect of age, a group of 13 healthy young adults (aged 20-24 years) were compared with a group of 8 older adults (aged 53-65 years). Also, the interaction between age and speed was analyzed. Regarding speed, there was a significant difference between forefoot/hindfoot motion in the sagittal plane (flexion/extension) during both loading- and push-off phase (P = .004, P < .001). Between hindfoot/tibia, there was a significant difference for all parameters except for motion in the sagittal plane (flexion/extension) during push-off phase (P = .5). Age did not significantly influence kinematics. There was no interaction between age and speed. Our analysis found that speed significantly influenced the kinematic outcome parameters. This was more pronounced in the ankle joint. In contrast, no significant differences were found between younger and older healthy subjects.

Diffusion-weighted magnetic resonance imaging (MRI) provides a way to generate in vivo lung images with contrast sensitive to the molecular displacement of inhaled gas at subcellular length scales. Here, we aimed to evaluate hyperpolarized 3He MRI estimates of the alveolar dimensions in 38 healthy elderly never-smokers (73 ± 6 years, 15 males) and 21 elderly ex-smokers (70 ± 10 years, 14 males) with (n = 8, 77 ± 6 years) and without emphysema (n = 13, 65 ± 10 years). The ex-smoker and never-smoker subgroups were significantly different for FEV1/FVC (P = 0.0001) and DLCO (P = 0.009); while ex-smokers with emphysema reported significantly diminished FEV1/FVC (P = 0.02) and a trend toward lower DLCO (P = 0.05) than ex-smokers without emphysema. MRI apparent diffusion coefficients (ADC) and CT measurements of emphysema (relative area–CT density histogram, RA950) were significantly different (P = 0.001 and P = 0.007) for never-smoker and ex-smoker subgroups. In never-smokers, the MRI estimate of mean linear intercept (260 ± 27 μm) was significantly elevated as compared to the results previously reported in younger never-smokers (210 ± 30 μm), and trended smaller than in the age-matched ex-smokers (320 ± 72 μm, P = 0.06) evaluated here. Never-smokers also reported significantly smaller internal (220 ± 24 μm, P = 0.01) acinar radius but greater alveolar sheath thickness (120 ± 4 μm, P < 0.0001) than ex-smokers. Never-smokers were also significantly different than ex-smokers without emphysema for alveolar sheath thickness but not ADC, while ex-smokers with emphysema reported significantly different ADC but not alveolar sheath thickness compared to ex-smokers without CT evidence of emphysema. Differences in alveolar measurements in never- and ex-smokers demonstrate the sensitivity of MRI measurements to the different effects of smoking and aging on acinar morphometry. PMID:26462748

This study, aimed to evaluate the difference in mucociliary clearance among volunteers who underwent Ramadan versus Nineveh fasting regimens as well as the difference between the fasting period and 4 weeks following the fasting period in both groups. In this study, two different fasting groups were established: Ramadan (fasting for an average of 15 h for 29 consecutive days, n = 40) and Nineveh (60 h of nonstop fasting, n = 26). Subjects in each group underwent saccharin testing twice: at the end of the fasting period prior to resumption of eating and at 4 weeks after the end of Ramadan or Nineveh fasting. Statistical analysis was performed using the Mann-Whitney U-test, Wilcoxon, Chi-square, and paired t test. A p value less than 0.05 was considered statistically significant. Forty subjects who underwent Ramadan fasting and 26 subjects who underwent Nineveh fasting were included in this study. Of the 66 study participants, 34 (51.5 %) were men and 32 (48.5 %) were women. Their median age was 31 years (range 17-70 years) for Nineveh fasting subjects and 40 years (range 17-70 years) for Ramadan fasting subjects. Chi-square tests revealed no significant difference between the Ramadan and Nineveh fasting groups in gender (p = 0.418), and the Mann-Whitney U-test showed no difference in age. A statistically significant difference was found in the mucociliary clearance time between the Nineveh fasting and non-fasting periods (p = 0.013). Using Wilcoxon signed-rank tests, we found no significant difference in the mucociliary clearance time between the Ramadan fasting and control (4 weeks after the fasting period) periods (p = 0.121). The percentage difference between the fasting and control periods was similar between groups and was not statistically significant for the Ramadan and Nineveh fasting groups (p = 0.086). The results of the present study indicated that long-term fasting with hypohydration contributed to the deterioration of nasal mucociliary clearance. Our data indicate that optimal hydration, sleep patterns, and fasting times contribute to proper mucociliary clearance.

Antigenic extracts prepared from pollen samples collected at weekly intervals during the same season did not exhibit significant variation in protein concentration. Stored pollen samples from different years, however, showed highly significant variations in protein concentration. The protein content of samples from different ecozones of India also varied (CV = +/- 32%). The IEF and SDS-PAGE patterns were almost identical in samples from the same season, but were variable in the samples stored from different years and different parts of India. IgE binding proteins from different samples also varied depending on the overall protein profiles. Almost all the patients, however, showed IgE binding to four proteins at 50, 60, 66 and 70 kD, indicating the important allergenic components of Holoptelea integrifolia.

Growth retardation and under-nutrition are common in children with sickle cell disease (SCD). The aim of this study was to compare the head circumference (HC) of SCD children and non-SCD children and to determine the effect of malnutrition on head circumference of children with SCD. This was a prospective case-control study conducted at the Lagos State University Teaching Hospital, Nigeria, involving SCD children (subject, n = 118) and non-SCD children (control, n = 118) matched for age, sex, and socioeconomic status. Weight, height and HC were measured using standard techniques. The mean ages of children with and without SCD were 7.46 ± 3.69 years and 7.01 ± 3.58 years, respectively. The HC increased significantly with age in both males and females (r = 0.75, p = < 0.001; r = 0.70, p < 0.001 respectively). There was no significant difference in HC between males and females (p > 0.05). At all ages, the mean head circumference of SCD children was not significantly (p > 0.05) different from non-SCD children. The In the age group 11-15 years, the prevalence of stunting was significantly higher among SCD children than non-SCD children. The mean HC of SCD children with stunting was significantly lower than those not stunted (51.7 vs. 53.5; P= 0.006) in age group 11.15 years. The head circumference of children with SCD is not significantly different from that of non-SCD children. Therefore, the HC chart for the general population is also applicable for monitoring head growth in children with SCD. The effect of malnutrition on head circumference of SCD children is most marked in age group 11-15 years.

The aim of this research was to compare the differences between patients with myofascial pain and disc displacement and asymptomatic individuals based on aspects of psychologic status and sleep quality. One hundred thirty patients (81 women, 49 men; mean ages: 30.0 and 31.0 years, respectively) with temporomandibular disorder were selected, and 64 control subjects (32 women, 32 men; mean ages: 27.2 and 27.5 years, respectively) were included in the investigation over a period of 1 year. Clinical diagnosis of 65 patients with myofascial pain and 65 patients with disc displacement with or without limitation and joint pain was determined according to the Research Diagnostic Criteria for Temporomandibular Disorders. The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality. Psychologic status was assessed using Symptom Checklist-90-Revised (SCL-90-R). Chi-square, Kolmogorov-Smirnov, one-way analysis of variance, and Tukey Honestly Significant Difference post hoc multiple comparison or Tamhane T2 tests were used for statistical analysis. There was a significant difference between patients with myofascial pain and disc displacement regarding somatization and paranoid ideation. No statistically significant difference was found between patients with disc displacements and controls in all dimensions of the SCL-90-R. Total score for the PSQI was statistically significantly different between patients with myofascial pain and controls; no significant differences were found between patients with disc displacement and those with myofascial pain or controls regarding the PSQI. To manage patients with myofascial pain, psychologic assessments including sleep quality should be considered.

We compared the semiology of psychogenic nonepileptic seizures (PNES) between patients from the USA and Brazil. This international cross-cultural comparative study may expand understanding of PNES across the borders. We retrospectively investigated all patients with PNES admitted to one epilepsy center in the USA and one in Brazil. We classified their seizures into four classes: generalized motor, akinetic, focal motor, and subjective symptoms. All patients were interviewed by an epileptologist in both countries and were administered psychological assessment measures, including questions about PNES risk factors. For the statistical analyses, we compared patients from the two nations. Eighty-nine patients (49 from the USA and 40 from Brazil) were studied. Patients from the two countries were not significantly different with regard to sex and age, but patients from Brazil had earlier age at onset (26years vs. 34years; P=0.004) and a significantly greater delay in diagnosis (9.9years vs. 5.6years; P=0.001). Some characteristics of PNES were different between the two groups; patients from the USA had generally more seizure types and more often reported subjective seizures (55% in the USA vs. 10% in Brazil; P=0.0001). Clinical and historical characteristics of the patients were not significantly different. Delay in diagnosis of PNES may represent a major factor in resource-limited countries. Large multicenter cross-cultural studies may reveal subtle but significant cross-cultural differences with respect to the semiological, clinical, and historical aspects of PNES; however, patients with PNES share more similarities than differences.

2014-07-01
The aim of this study was to examine differences in several aspects of health between Kuwaiti men and women aged 60 years and over across three age categories (60-69, 70-79, 80+ years). The relationships between several social support variables, somatic symptoms and systolic and diastolic blood pressures were examined. A total of 1427 adult men (472) and women (955) aged 60 years and over representing all six governorates were selected. Data were collected during 2008-2009 by interview and completion of a questionnaire by participants in their own homes, after obtaining their informed consent. The Social Support Scale (SSS), Frequency of Contact Scale (FOC), Strength of Relations (SOR), Somatic Symptoms Inventory (SSI) and self-rated scales of general health were included. Systolic and diastolic blood pressures were measured. The data show that self-rated health and health in the last year differ significantly across age groups. Glycaemia differed significantly across the three age groups for the total sample. Systolic and diastolic blood pressure were higher in older respondents than younger ones, but no significant differences were observed between men and women. No significant differences in somatic symptoms were observed across the three age groups. Strength of relationship, frequency of contact, social support and children living with an elderly adult were all associated with fewer somatic symptoms, and all, except social support, were associated with lower systolic and diastolic blood pressure. Having children, the perception of social support, frequency of contact with, and strength of, relationships with kin are important modulators of somatic symptoms and blood pressure among elderly Kuwaitis.

It has been hypothesized that dexamethasone can inhibit persistent postoperative pain, but data on humans is lacking and results from animal studies are conflicting. We explored the effect of 16 mg dexamethasone IV administered preoperatively on persistent pain 1 year after lumbar discectomy. This is a prospective 1-year follow-up on a single-centre, randomized, and blinded trial exploring the analgesic effect of 16 mg IV dexamethasone or placebo after lumbar discectomy. One year follow-up was a written questionnaire including back and leg pain (VAS 0-100 mm), Short Form 36 survey (SF-36), EuroQol 5D (EQ-5D), OSWESTRY Low Back Pain Questionnaire, duration of sick leave, working capability, contentment with surgical result. Response rate was 71% (55 patients) in the dexamethasone group, 58% (44 patients) in the placebo group. Leg pain (VAS) was significantly lower in the placebo group compared to the dexamethasone group: 17 (95% CI 10-26) vs 26 (95% CI 19-33) mm, respectively (mean difference 9 mm (95% CI -1 to 0), (P = 0.03). No difference regarding back pain. The placebo group reported significantly more improvement of leg pain and were significantly more satisfied with the surgical result. Patients in the dexamethasone group reported significantly higher pain levels in EQ-5D- and Oswestry questionnaires. No difference in the SF-36 survey or daily analgesic consumption. We found significantly higher pain levels in the dexamethasone group compared to placebo 1 year after lumbar disc surgery. Clinicaltrials.gov ( NCT01953978 ). Registered 26 Sep 2013.

Summary Background: This study was designed to determine the short- and long-term effects of proximal aortic anastomosis, performed during isolated coronary artery bypass grafting (CABG) in patients with dilatation of the ascending aorta who did not require surgical intervention. Methods: The study was performed on 192 (38 female and 160 male patients; mean age, 62.1 ± 9.2 years; range, 42–80 years) patients with dilatation of the ascending aorta who underwent CABG surgery between 1 June 2006 and 31 May 2014. In group 1 (n = 114), the saphenous vein and left internal mammarian artery grafts were used, and proximal anastomosis was performed on the ascending aorta. In group 2 (n = 78), left and right internal mammarian artery grafts were used, and proximal aortic anastomosis was not performed. Pre-operatively and in the first and third years postoperatively, the ascending aortic diameter was measured and recorded using transthoracic echocardiography at four different regions (annulus, sinus of Valsalva, sinotubular junction and tubular aorta). Results: A statistically significant difference was found between the groups for the number of grafts used and the duration of aortic cross-clamping and cardiopulmonary bypass. No significant intergroup difference was seen for the mean diameter of the ascending aorta (p > 0.05). Annual changes in the aortic diameter were found to be extremely significantly different in both groups (p = 0.0001). Mean values of the aortic diameter at the level of the sinotubular junction and tubular ascending aorta, mean aortic diameters (p = 0.002 and p = 0.0001, respectively), annual increase in diameter (p = 0.0001 and p = 0.0001, respectively), and mean annual difference in diameter (p = 0.0001 and p = 0.0001, respectively) at one and three years postoperatively were statistically significantly different between the groups. Conclusion: In patients with ascending aortic dilatation who did not require surgical intervention and who had proximal anastomosis of the ascending aorta and underwent only CABG, we detected statistically significant increases in the diameter of the sinotubular junction and tubular aorta up to three years postoperatively.

Objectives: The objective of this study was measurement of urine flow parameters by a non invasive urodynamic test. Variation of flow rates based on voided volume, age, and gender are described. Different nomograms are available for different populations and racial differences of urethral physiology are described. Currently, there has been no study from the Indian population on uroflow parameters. So the purpose of this study was to establish normal reference ranges of maximum and average flow rates, to see the influence of age, gender, and voided volume on flow rates, and to chart these values in the form of a nomogram. Methods: We evaluated 1,011 uroflowmetry tests in different age groups in a healthy population (healthy relatives of our patients) 16-50 year old males, >50 year old males, 5-15 year old children, and >15 year pre-menopausal and post-menopausal females. The uroflowmetry was done using the gravitimetric method. Flow chart parameters were analyzed and statistical calculations were used for drawing uroflow nomograms. Results: Qmax values in adult males were significantly higher than in the elderly and Qmax values in young females were significantly higher than in young males. Qmax values in males increased with age until 15 years old; followed by a slow decline until reaching 50 years old followed by a rapid decline after 50 years old even after correcting voided volume. Qmax values in females increased with age until they reached age 15 followed by decline in flow rate until a pre-menopausal age followed by no significant decline in post-menopausal females. Qmax values increased with voided volume until 700 cc followed by a plateau and decline. Conclusions: Qmax values more significantly correlated with age and voided volume than Qavg. Nomograms were drawn in centile form to provide normal reference ranges. Qmax values in our population were lower than described in literature. Patients with voided volume up to 50 ml could be evaluated with a nomogram. PMID:19955668

Objective To analyze rates of significant adverse events and outcomes in women having a medical abortion at Planned Parenthood health centers in 2009 and 2010, and to identify changes in the rates of adverse events and outcomes between the 2 years. Methods In this database review we analyzed data from Planned Parenthood affiliates that provided medical abortion in 2009 and 2010, almost exclusively using an evidence-based buccal misoprostol regimen. We evaluated the incidence of six clinically significant adverse events (hospital admission, blood transfusion, emergency room treatment, intravenous antibiotics administration, infection, and death) and two significant outcomes (ongoing pregnancy and ectopic pregnancy diagnosed after medical abortion treatment was initiated). We calculated an overall rate as well as rates for each event and identified changes between the 2 years. Results Amongst 233,805 medical abortions provided in 2009 and 2010, significant adverse events or outcomes were reported in 1,530 cases (0.65%). There was no statistically significant difference in overall rates between years. The most common significant outcome was ongoing intrauterine pregnancy (0.50%); significant adverse events occurred in 0.16% of cases. One patient death occurred due to an undiagnosed ectopic pregnancy. Only rates for emergency room treatment and blood transfusion differed by year, and were slightly higher in 2010. Conclusion Review of this large dataset reinforces the safety of the evidence-based medical abortion regimen. PMID:23262942

To evaluate the possible side effects and potential protection 5 years after implantation of an intraocular lens (IOL) with a blue-light filter (yellow tinted). Ophthalmology Department, University of São Paulo, São Paulo, Brazil. Prospective randomized clinical study. Patients with bilateral visually significant cataract randomly received an ultraviolet (UV) and blue light-filtering IOL (Acrysof Natural SN60AT) in 1 eye and an acrylic UV light-filtering only IOL (Acrysof SA60AT) in the fellow eye. The primary outcome measures were contrast sensitivity, color vision, and macular findings 5 years after surgery. The study enrolled 60 eyes of 30 patients. There were no significant clinical or optical coherence tomography findings in terms of age-related macular degeneration in any eye. There were no statistically significant differences in central macular thickness between the 2 IOL groups (P=.712). There were also no significant between-group differences under photopic or scotopic conditions at any spatial frequency studied. No statistically significant differences in the color discrimination test were found between the 2 IOL groups (P=.674). After 5 years, there were no significant differences in color perception, scotopic contrast sensitivity, or photopic contrast sensitivity between the blue light-filtering (yellow-tinted) IOL and the IOL with a UV-light filter only (untinted). The potential advantage of the tinted IOL in providing protection to macular cells remains unclear. Copyright © 2011 ASCRS and ESCRS. Published by Elsevier Inc. All rights reserved.

Although early in life there is little discernible difference in bone mass between boys and girls, at puberty sex differences are observed. It is uncertain if these differences represent differences in bone mass or just differences in anthropometric dimensions. The study aimed to identify whether sex independently affects bone mineral content (BMC) accrual in growing boys and girls. Three sites are investigated: total body (TB), femoral neck (FN) and lumbar spine (LS). 85 boys and 67 girls were assessed annually for seven consecutive years. BMC was assessed by dual energy X-ray absorptiometry (DXA). Biological age was defined as years from age at peak height velocity (PHV). Data were analysed using a hierarchical (random effects) modelling approach. When biological age, body size and body composition were controlled, boys had statistically significantly higher TB and FN BMC at all maturity levels (p < 0.05). No independent sex differences were found at the LS (p > 0.05). Although a statistical significant sex effect is observed, it is less than the error of the measurement, and thus sex difference are debatable. In general, sex difference are explained by anthropometric difference.
White matter properties differ in 6-year old Readers and Pre-Readers

Reading, an essential life skill in modern society, is typically learned during childhood. Adults who can read show white matter differences compared to adults who never learned to read. Studies have not established whether children who can read show similar white matter differences compared to children who cannot read. We compared 6-year old children who could decode written English words and pseudowords (n=31; Readers) and 6-year old children who could not decode pseudowords and had a standard score < 100 on a task for reading single words (n=11; Pre-Readers). We employed diffusion MRI and tractography to extract fractional anisotropy (FA) along the trajectory of 6 bilateral intra-hemispheric tracts and 2 posterior subdivisions of the corpus callosum. Readers demonstrated significantly increased FA within the left anterior segment of the superior longitudinal fasciculus (aSLF-L) and the right uncinate fasciculus (UF-R) compared to Pre-Readers. FA in the aSLF-L was significantly correlated with phonological awareness; FA in the UF-R was significantly correlated with language. Correlations in the UF-R but not the aSLF-L remained significant after controlling for reading ability, revealing that UF-R group differences were related to both children's language and reading abilities. Taken together, these findings demonstrate new evidence showing that individual differences in white matter structure relate to whether children have begun to read. PMID:27631434
Boldness in two perch populations - long-term differences and the effect of predation pressure.
Magnhagen, Carin; Hellström, Gustav; Borcherding, Jost; Heynen, Martina
2012-11-01
1. Populations of the same species often display different behaviours, for example, in their response to predators. The question is whether this difference is developed as part of a divergent selection caused by differences in predation pressure, or as a result of phenotypic responses to current environmental conditions. 2. Two populations of Eurasian perch were investigated over a time span of 6 years to see whether risk-taking behaviour in young-of-the-year perch were consistent across cohorts, or if behaviour varied over time with changes in predation regime. 3. Boldness was estimated in aquarium studies by looking at how the fish made trade-offs between foraging in a risky area and staying in shelter. Predation risk of each year and lake was estimated from fishing surveys, using an individual-based model calculating attack rates for cannibalistic perch. 4. The average boldness scores were consistently lower in perch from Fisksjön compared with those in Ängersjön, although the magnitude of the difference varied among years. Variance component analyses showed that differences between lakes in boldness scores only explained 12 per cent of the total variation. Differences between years were contributing at least similarly or more to the total variance, and the variation was higher in Fisksjön than in Ängersjön. 5. The observed risk-taking behaviour of young-of-the-year perch, compared across cohorts, was significantly correlated with the year-specific estimates of cannibalistic attack rates, with lower boldness scores in years with higher predation pressure. In Fisksjön, with significant changes over the years in population structure, the range of both predation risk and boldness scores was wider than in Ängersjön. 6. By following the two perch populations over several years, we have been able to show that the differences in risk-taking behaviour mainly are due to direct phenotypic responses to recent experience of predation risk. Long-term differences in behaviour among perch populations thus reflect consistent differences in predation regime rather than diverging inherent traits. © 2012 The Authors.

Consumption of sugar-sweetened beverages may cause excessive weight gain. We aimed to assess the effect on weight gain of an intervention that included the provision of noncaloric beverages at home for overweight and obese adolescents. We randomly assigned 224 overweight and obese adolescents who regularly consumed sugar-sweetened beverages to experimental and control groups. The experimental group received a 1-year intervention designed to decrease consumption of sugar-sweetened beverages, with follow-up for an additional year without intervention. We hypothesized that the experimental group would gain weight at a slower rate than the control group. Retention rates were 97% at 1 year and 93% at 2 years. Reported consumption of sugar-sweetened beverages was similar at baseline in the experimental and control groups (1.7 servings per day), declined to nearly 0 in the experimental group at 1 year, and remained lower in the experimental group than in the control group at 2 years. The primary outcome, the change in mean body-mass index (BMI, the weight in kilograms divided by the square of the height in meters) at 2 years, did not differ significantly between the two groups (change in experimental group minus change in control group, -0.3; P=0.46). At 1 year, however, there were significant between-group differences for changes in BMI (-0.57, P=0.045) and weight (-1.9 kg, P=0.04). We found evidence of effect modification according to ethnic group at 1 year (P=0.04) and 2 years (P=0.01). In a prespecified analysis according to ethnic group, among Hispanic participants (27 in the experimental group and 19 in the control group), there was a significant between-group difference in the change in BMI at 1 year (-1.79, P=0.007) and 2 years (-2.35, P=0.01), but not among non-Hispanic participants (P>0.35 at years 1 and 2). The change in body fat as a percentage of total weight did not differ significantly between groups at 2 years (-0.5%, P=0.40). There were no adverse events related to study participation. Among overweight and obese adolescents, the increase in BMI was smaller in the experimental group than in the control group after a 1-year intervention designed to reduce consumption of sugar-sweetened beverages, but not at the 2-year follow-up (the prespecified primary outcome).

In this study, we performed a comprehensive analysis of the transcriptome of one- and two-year-old male and female brains of Cynoglossus semilaevis by high-throughput Illumina sequencing. A total of 77,066 transcripts, corresponding to 21,475 unigenes, were obtained with a N50 value of 4349 bp. Of these unigenes, 33 genes were found to have significant differential expression and potentially associated with growth, from which 18 genes were down-regulated and 12 genes were up-regulated in two-year-old males, most of these genes had no significant differences in expression among one-year-old males and females and two-year-old females. A similar analysis was conducted to look for genes associated with reproduction; 25 genes were identified, among them, five genes were found to be down regulated and 20 genes up regulated in two-year-old males, again, most of the genes had no significant expression differences among the other three. The performance of up regulated genes in Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis was significantly different between two-year-old males and females. Males had a high gene expression in genetic information processing, while female's highly expressed genes were mainly enriched on organismal systems. Our work identified a set of sex-biased genes potentially associated with growth and reproduction that might be the candidate factors affecting sexual dimorphism of tongue sole, laying the foundation to understand the complex process of sex determination of this economic valuable species.

Eighty-one healthy prepubertal children of short stature, between two and twelve years of age, were divided into four homogeneous groups. Each group was treated with a placebo for one year and for a second year with one of the following drugs (double blind): clonidine (CI), arginine asprate (AA), ornithine alphaketoglutare (OKG), or cyproheptadine (Cp). CI and OKG did not better the standard deviation of height. AA and Cp did, but to no greater extent than the placebo. The growth rate did not change in any group. The ratio of bone age/chronological age was significantly higher at the end of the OKG year than at the end of the year with placebo, a difference that was not found in any other group. The prognosis of adult height (TW2) did not change in any group. The standard deviation of weight increased in all groups, both with the placebo and the various drugs, without significant differences between the groups. The CI caused frequent clinical side effects, including a reversible increase in transaminases in one child. The Cp stimulated hunger. The AA and OKG did not produce side-effects and the placebo increased appetite in 11% of the children. Somatomedin C was significantly higher after one year with Cp than after one year with the placebo, significantly higher after the placebo than after CI and AA and there was no difference between the treatment with the placebo and OKG. Growth hormone values in a 24 hour urine sample were so scattered that we do not consider them helpful.(ABSTRACT TRUNCATED AT 250 WORDS)
Childhood obesity: the extent of the problem among 6-year-old Irish national school children.
Evans, D S; Glacken, M; Goggin, D
2011-05-01
Childhood obesity is rapidly increasing worldwide. In Ireland, the number of overweight children has trebled over the last decade. The study aimed to provide an assessment of the prevalence of obesity of 6-year-old children in one region of Ireland. Following training, School Public Health Nurses included the measurement of height and weight as part of the annual 'senior infants' school health check for 5453 6-year-old children in 189 schools between 2004 and 2007. Body mass index (BMI) was calculated using the International Obesity Taskforce cut-off points using lmsGrowth (a Microsoft Excel add-in), which uses a child's exact age. Kendall's Tau b was used to determine the reliability of measurements. Prevalence trends were tested using multinomial logistic regression. Pearson's chi-squared test was utilized to assess the statistical significance of differences in BMI by gender, school year, and to compare with similar other Irish studies. Out of the 5453 children measured, 3493 were aged 6 years old. A further 11 were excluded because of incomplete data. Data were analysed for 3482 6-year-old children. Overall, 27% of 6-year-olds were classified as either overweight or obese. A significantly greater proportion of girls are overweight or obese compared with boys (31% compared with 23%). Gender differences have remained relatively stable from 2004-2007. Overall, there have been no significant changes in the level of obesity from 2004-2007. In addition, when comparing with other Irish studies that collected data for 2001/2, there are no significant differences in obesity levels. There is a clear need to urgently prioritize the effective management of obesity. Resourses should now be targeted towards ensuring government policies in Ireland and elsewhere are implemented. © 2010 Blackwell Publishing Ltd.

Since high myopia in the younger generation may differ etiologically from high myopia in older generations, we examined whether education-related parameters differ between high myopia in today´s school children and high pathological myopia in today´s elderly generation. The investigation included the adult populations of the population-based Beijing Eye Study (BES) (3468 adults;mean age:64.6±9.8years;range:50-93years) and Central India Eye and Medical Study (CIEMS) (4711 adults;age:49.±13.2years;range:30-100years), and the children and teenager populations of the Shandong Children Eye Study (SCES) (6026 children;age:9.7±3.3years;range:4-18years;cycloplegic refractometry), Gobi Desert Children Eye Study (1565;age:11.9±3.5years;range:6-21 years;cycloplegic refractometry), Beijing Pediatric Eye Study (681 children;age:7.7±1.6years;range:5-13 years;non-cycloplegic refractometry,calculation of axial length to corneal curvature radius ratio), Beijing Children Eye Study (15066 children;age:13.2±3.4years;range:7-18years;non-cycloplegic refractometry), Beijing High School Teenager Eye Study (4677 children;age:16.9±0.7years;range:16-18years;non-cycloplegic refractometry). In the BES and CIEMS, educational level did not differ significantly between, or was significantly lower in the highly myopic group (myopic refractive error ≥6 diopters) than in the non-highly myopic group. In all non-adult study populations, higher prevalence of high myopia was significantly associated with higher degree of education related parameters such as attendance of high-level schools, and more time spent for indoors near work versus time spent outdoors. Comparing associations of old or genetic high myopia in adults with new or acquired high myopia in school children revealed that education-related parameters did not show a clear association with old or genetic high myopia, while in contrast, new high myopia showed strong associations with education. It confirms previous studies that the two forms of high myopia not only differed in age of onset, but also in associations with education as well. The data support the notion of two types of high myopia. Future studies may assess whether the risk of pathologic myopic maculopathy and high myopia associated open-angle glaucoma differs between both types of high myopia.
Adolescents conceived by IVF: parenting and psychosocial adjustment.
Colpin, H; Bossaert, G
2008-12-01
A follow-up study was conducted in mid-adolescence on parenting and the child's psychosocial development after in vitro fertilization (IVF). The first phase of the study had compared 31 IVF families and 31 families with a naturally conceived child when the children were 2 years old (Colpin et al., 1995). Of these, 24 IVF families and 21 control families participated again when the children were 15-16 years old. Fathers, mothers and adolescents completed questionnaires assessing parenting style and stress, and adolescent psychosocial adjustment. No significant differences were found in self- or adolescent-reported parenting style, or in parenting stress between IVF mothers and mothers in the control group, nor between IVF fathers and fathers in the control group. Neither did we find significant differences in self- or parent-reported behavioural problems between adolescents conceived by IVF and those conceived naturally. Comparison of behavioural problems between IVF adolescents informed or not informed about the IVF conception did not reveal significant differences. Parenting and 15-16-year-old adolescents' psychosocial adjustment did not differ significantly between IVF families and control families. This study is, to the best of our knowledge, the first psychosocial follow-up in mid-adolescence, and adds to the evidence that IVF children and their parents are well-adjusted. Large-scale studies in adolescence are needed to support these findings.
Educating teachers of nursing: the attitudes of students.
Sheahan, J
1982-01-01
One hundred and twenty-four experienced registered nurses representing four status categories (nurse managers, full-time student teachers of nursing, first year part-time student teachers of nursing, and second year part-time teachers of nursing) participated in a study to investigate the nature of their social attitudes. Oliver's Survey of Opinions about Education was used as a measure of social attitudes. The overall conclusion was that the social attitudes of the subjects in the study were more similar than dissimilar. Significant differences were found between the managers and the full time teachers (t = -2.03, P less than 0.05) on radicalism. The teachers were found to be more radical. Significant differences were found between the managers and the first year part-time teachers (t = 2.55, P less than 0.05) on tender-mindedness. The teachers were found to be more tender-minded. Significant differences were also found on tender-mindedness between the managers and the second year part-time teachers (t = -2.37, P less than 0.05). Again, the teachers were found to be more tender-minded than the managers. Apart from these differences, the social attitudes of the subjects were found to be well balanced. When the findings of the present study are compared with other studies relating to the social attitudes of nurses, the pattern which emerges in a more balanced one. However, previous studies mainly used subjects in the 18-21-year age group. The difference in the ages of the subjects is likely to be an important factor on their social attitudes, but further research would be required to determine whether factors other than a difference in ages play a part.

The purpose of this study was to perform a comprehensive audit of dental treatment provided to special needs patients (SNP) under general anesthesia (GA) over a ten-year period. Special needs patients who received dental treatment under GA as an in-patient at Queen Mary Hospital, Hong Kong SAR during the time period January 2002 and December 2011 were included in the study. The study population was divided into three groups, based on age (<6years, 6-12 years, >12 years). One-way ANOVA was used to evaluate the effect of "age group" on duration of treatment, post-recovery time, treatment procedures and utilization of different restorative materials. Kappa statistics were used for intra-examiner reliability. A total of 275 patients (174 males and 101 females) were included in the study. The mean age of the patients at the time they received GA was 12.37±10.18 years. Dental procedures performed were mostly restorative in nature (47%). The >12 years group had significantly shorter treatment duration (p<0.05). No significant difference in post-operative recovery time was observed among the three age groups (p>0.05). The <6 years group received significantly less preventive, but more restorative procedures (p<0.05). Significantly fewer extractions were performed in the 6-12 years group (p<0.05). The use of composite restorations was significantly higher in the <6 years group; while amalgam restorations were more frequently used in the >12 years group (P<0.05). Stainless steel crowns were more frequently employed in SNP under 12 years of age (p<0.05). Intra-examiner reliability was good (k=0.94). Most of the dental procedures performed under GA on SNP were restorative procedures. For children less than 6 years of age, had longer treatment time under GA. Composite restorations and stainless steel crowns were more frequently used in the primary dentition and amalgam restorations were more frequently employed in the permanent dentition.

To assess the impact of a culturally proficient dietary/physical activity intervention on changes in body mass index (BMI) (kg/m 2 ). Randomized controlled trial (Hip-Hop to Health Jr.) conducted between September 1999 and June 2002 in 12 Head Start preschool programs in Chicago, Illinois. Intervention children had significantly smaller increases in BMI compared with control children at 1-year follow-up, 0.06 vs 0.59 kg/m 2 ; difference -0.53 kg/m 2 (95% CI -0.91 to -0.14), P = .01; and at 2-year follow-up, 0.54 vs 1.08 kg/m 2 ; difference -0.54 kg/m 2 (95% CI -0.98 to -0.10), P = .02, with adjustment for baseline age and BMI. The only significant difference between intervention and control children in food intake/physical activity was the Year 1 difference in percent of calories from saturated fat, 11.6% vs 12.8% ( P = .002). Hip-Hop to Health Jr. was effective in reducing subsequent increases in BMI in preschool children. This represents a promising approach to prevention of overweight among minority children in the preschool years.

The present longitudinal study explored the development of personal well-being in university students over 4 years. Personal well-being was indexed by multiple indicators including life satisfaction, positive youth development qualities, and university engagement. A sample of 434 students enrolled in the new 4-year undergraduate program in one university in Hong Kong was successfully followed up for 4 years since they started their university study in 2012-2013 academic year. Students completed an online survey on a yearly basis and four waves of data were collected. Results revealed significant changes in most well-being indicators over time with three main observations. First, students' life satisfaction remained at a stable level during 4 years. Second, most students' self-reported positive youth development competencies followed a U-shaped developmental trajectory, which was characterised by a dip in the second year and a continuous rebound in the third year and fourth year. Third, students' university engagement in different aspects showed significant increments in the third and fourth year of university study. The findings underscore the disparate developmental patterns of different aspects of student well-being during university study. This suggests that there is a need to take into account students' developmental characteristics and related challenges in different stages of university life when develop and implement programs in university to promote student well-being.

Introduction: Local ablative therapy and trans arterial chemoembolization (TACE) are applied to ablate non resectable hepatocellular carcinoma (HCC). Combination of both techniques has proven to be more effective. We aimed to study combined ablation techniques and assess survival benefit comparing TACE with radiofrequency (RFA) versus TACE with microwave (MWA) techniques. Methods: We retrospectively studied 22 patients who were ablated using TACE-RFA and 45 with TACE-MWA. All were classified as Child A-B and lesions did not exceed 5 cm in diameter. TACE was followed within two weeks by either RFA or MWA. We recorded total and partial ablation rates and complication rates. Survival analysis was then performed. Results: TACE-MWA showed a higher tendency to provide complete response rates than TACE-RFA (P 0.06). This was particularly evident with lesions sized 3-5 cm (P 0.01). Rates of complications showed no significant difference between the groups. Overall median survival was 27 months. The overall actuarial probability of survival was 80.1% at 1 year, 55% at 2 years, and 36.3% at 3 years. The recurrence free survival at 1 year, 2years and 3 years for the TACE-RFA group was 70%, 42% and 14% respectively and for TACE-MWA group 81.2%, 65.1% and 65.1% without any significant difference (P 0.1). In relation to the size of focal lesions, no statistically significant difference in the survival rates was detected between the groups. Conclusion: TACE-MWA led to better response rates than TACE-RFA with tumors 3-5 cm, with no difference in survival rates. PMID:28240516

Effects of forest management on fungal diversity were investigated by sampling fruit bodies of polyporoid and corticioid fungi in forest stands that have different management histories. Fruit bodies were sampled in 15 northern hardwood stands in northern Wisconsin and the upper peninsula of Michigan. Sampling was conducted in five old-growth stands, five uneven-age stands, three even-age unthinned stands and two even-age thinned stands. Plots 100 m x 60 m were established and 3000 m2 within each plot was sampled during the summers of 1996 and 1997. A total of 255 polyporoid and corticioid morphological species were identified, 46 (18%) of which could not be assigned to a described species. Species accumulation curves for sites and management classes differed from straight lines, although variability from year to year suggests that more than 2 y of sampling are needed to characterize annual variation. Mean species richness and diversity index values did not vary significantly by management class, although mean richness on large diameter wood (> or = 15 cm diam) varied with moderate significance. Richness values on small diameter debris varied significantly by year, indicating that a large part of year-to-year variability in total species richness is due to small diameter debris. Ten species had abundance levels that varied by management class. Two of these species. Changes in the diversity and species composition of the wood-inhabiting fungal community could have significant implications for the diversity, health and productivity of forest ecosystems.

The aim of this study was to assess the relationship between burnout, depressive symptoms and suicidal ideation in dental and dental hygiene students and to evaluate the influence of gender, programme type and year of study. Third- and fourth-year dental (DS) and first- and second-year hygiene students (DHS) completed the Patient Health Questionnaire (PHQ-9) and an abbreviated Maslach Burnout Inventory online as measures of depressive symptoms/suicidality and burnout, respectively. The statistical analyses included summary statistics and tests for intergroup comparisons (chi-square) to evaluate the influence of gender, programme type (DHS or DS) and year of study. Correlations between depression, suicidality and burnout were also conducted. A total of 32 dental hygiene and 119 dental students participated. 40% of the dental and 38% of the hygiene students met criteria for burnout. No differences were found between years or between programmes. Nine per cent of both dental and hygiene students were above the cut-off for moderate depressive symptoms, but there were no statistical differences between the third- and fourth-year dental and the first- and second-year hygiene students. Six per cent of the dental and 9% of the dental hygiene students were above the cut-off for clinically significant suicidal ideation, but there were no statistical differences between dental and hygiene students. There were no differences noted in the dental students based on gender for any of the measures. Depression was significantly associated with all three subscales of burnout. Suicidal ideation was only significantly related to the lack of personal accomplishment subscale of burnout. These findings suggest the need for introducing preventive measures for such affective states in dental and dental hygiene training programmes. © 2017 John Wiley & Sons A/S.

This study examined the assessment of the negative emotional constructs of depression, anxiety and stress with the short version (21 items) of the Depression Anxiety Stress Scales (DASS-21) in elderly patients (age > 60 years) with persistent pain. A convenience sample of 2,045 patients attending a tertiary referral pain centre were categorized by age and included a group aged 60 years and under (n=1,245) for assessment of age differences. Elderly patients (n=800) were divided into 3 groups: 61-70 years (n=366), 71-80 years (n=308) and 81 years and over (n=126). Patients completed the DASS-21 as part of an initial clinical assessment process. The failure rate for scale completion increased across age groups and was significantly higher in the oldest group compared to the youngest group. All scales demonstrated reasonable convergent and divergent validity. Confirmatory factor analysis confirmed a three-factor structure and is consistent with previous studies. Age differences in depression, anxiety and stress scores were also assessed. Interestingly, patients aged 60 years and under had significantly higher Depression and Stress scores compared to all other age groups. This group also had significantly higher Anxiety scores compared to patients aged 61-70 years. Overall, the DASS-21 is a reliable and valid measure of depression, anxiety and stress in elderly patients with persistent pain. There are some age differences in the normative values for the reporting of mood symptoms and these need to be taken into account when assessing pain-related mood disturbance in older populations.

ArRejaie, Aws S
2014-07-01
To evaluate the effect of long term utilization of chemical disinfectants on the color of porcelain shade guides. three chemical disinfectants were used in this study: Minuten spray, Lysol ICQuaternary Disinfectant Cleaner (QDC), and Lysol IC Ready to Use Disinfectant Cleaner (RDC). Simulation of disinfecting cycles for one year, two years, and three years were done on Vita 3D master shade guide. Color differences were determined by visual inspection and analyzing ΔE. ΔE values were significantly below the perceptible (ΔE=1) and the clinically acceptable (ΔE=3.7) thresholds. Simulated utilization of Minuten Spray, Lysol IC (QDC), and Lysol (RDC) disinfectants for up to three years didn't cause a clinically significant difference in the color of VITA Toothguide 3D-Master Shade Guide.

To investigate the prevalence rate of thalassemia among children of 0 - 7 years old, from six ethnic groups in Xishuangbanna and Dehong, Yunnan province. 4973 blood samples from children under 7 years old were automatically undergone blood cell count, red cell osmotic fragility and hemoglobin electrophoresis testings. The incidence rates of thalassaemia, β-thalassemia was 37.4%, and α-thalassaemia were 22.6% and 14.7% respectively. The thalassaemia incidence rates were significantly different among age groups but not in gender. The incidence of α-thalassaemia was decreasing along with the increase of age, while the incidence of β-thalassaemia was increasing along with the increase of age. Xishuangbanna had the higher incidence than in Dehong and the differences were significant between counties, The incidence of thalassemia of Mengla ranked the first (52.2%) in Xishuangbanna, The differences between different regions and different nationalities were significant, with β-thalassemia of Achang ranked the first (40.6%), The incidence of α-thalassemia among Han ranked the first as 45.5% while α-thalassaemia and β-thalassemia were different in regions. α-thalassaemia and β-thalassemia were significantly different between different ethnic people in the same regions. Multiple factor analysis showed that region seemed to be a risk factor and the mother's ethnicity was a protective factor and dependent variable on thalassaemia. The incidence of thalassaemia in Yunnan Xishuangbanna and Dehong was high among children under the age of 7 and were related to ethnic and regional differences in the areas. Specific genes were proliferated along with the extension of time. Our data provided valuable information on prevention and genetic studies on thalassaemia in the minorities of Xishuangbanna and Dehong in Yunnan province.

Two thousand fifteen has been a winning year for Drug Eluting Stents (DES). Increase in the number of patients with cardiovascular diseases treated by Percutaneous Coronary Intervention (PCI) has resulted to a high demand for second generation DES. This current analysis aimed to compare the different types of Stent Thrombosis (ST) associated with Zotarolimus Eluting Stents (ZES) versus Everolimus Eluting Stents (EES) at 1 year follow up. Electronic databases were searched for studies comparing ZES with EES. Different types of ST reported at 1 year follow up were considered as the primary endpoints in this analysis. Odds Ratios (OR) with 95% Confidence Intervals (CIs) were used as the statistical parameters and the pooled analyses were carried out by the RevMan 5 · 3 software. A total number of 10,512 patients were included in this analysis. No significant difference in any definite ST, acute definite ST, subacute definite ST, and late definite ST were observed between ZES and EES, at 1 year follow up with OR: 1.70, 95% CI: 0.92 - 3.16; P = 0.09, OR: 3.44, 95% CI: 0.82 - 14.43; P = 0.09, OR: 1.13, 95% CI: 0.43 - 2.95; P = 0.80 and OR: 2.39, 95% CI: 0.83 - 6.85; P = 0.11 respectively. Moreover, any definite or probable ST and definite/probable/possible ST were also not significantly different with OR: 1.39, 95% CI: 0.89 - 2.17; P = 0.15 and OR: 1.19, 95% CI: 0.84 - 1.70; P = 0.33 respectively. In addition, any probable ST, acute probable ST, late probable ST and possible ST were also not significantly different at 1 year follow up with OR: 1.11, 95% CI: 0.60 - 2.05; P = 0.75, OR: 0.53, 95% CI: 0.12 - 2.40; P = 0.41, OR: 1.67, 95% CI: 0.35 - 7.86; P = 0.52 and OR: 1.08, 95% CI: 0.64 - 1.82; P = 0.78 respectively. At 1 year follow up, ZES were not associated with significantly lower or higher definite and probable ST compared to EES. In addition, no significant difference was observed in acute, subacute and late definite or probable ST. However, further trials are recommended to assess the effects of these second-generation DES during the long-term.

Yeso sika deer captured in winter around Lake Akan in Hokkaido were reared for 8-10 months at Tokyo University of Agriculture in Abashiri. Six 1-year-old females and males and six 2-year-old or older (adult) females and males were slaughtered and their carcasses were processed. The chemical composition, mineral contents and fatty acid composition of the loin were measured. No marked influence of gender or age was noted in the chemical composition of loin. In the mineral contents, significant differences were noted. The potassium and sulfur contents were lower and the sodium content was higher in adult deer meat (P < 0.05, respectively) and the potassium content was higher in male deer meat (P < 0.05). Arsenic, cadmium or lead were not detected. In the unsaturated fatty acid, a significant interaction was detected (P < 0.05), and it was high in 1-year-old female deer meat and low in 1-year-old male deer meat. Significant gender or age differences were noted only in the mineral contents in the loin of deer reared for a short period after capture. © 2014 Japanese Society of Animal Science.

Many changes happen during growth and development in an organism as a result of important hormon changes, especially biohumoral ones. These changes make a problem when interpreting biochemical results in pediatric population. The most important changes are intensive calcium and phosphorus metabolic turnover in bone tissue with changes in alkaline phosphatase activity as a result of osteoblast activity. The aim of this study was to follow the serum calcium and phosphorus concentration and alkaline phosphatase activity in children 1-15 years old in different growth and development period and of different sexes and to fortify the influence of growth and development dynamics on biohumoral status in healthy male and female children. We evaluated 117 healthy children of both sexes from 1-15 years of age and divided them into three age groups: 1-5, 6-10 and 11-15 years. We followed the serum calcium and phosphorus concentration and alkaline phosphatase activity in different groups and in different sexes. Our investigation found significantly higher values of serum calcium in boys than in girls with no important changes between the age groups and significantly higher values of serum phosphorus in the youngest age group in all children and in different sexes with no important sex differences. Alkaline phosphatase activity followed the growth spurt and was the biggest in 6-10 years group in girls and in 11-15 years group in boys.
[Age and time estimation during different types of activity].

The study was concerned with the age characteristics of verbal and operative estimation of time intervals filled with different types of mental and physical activity as well as those free of it. The experiment was conducted on 85 subjects, 7--24 years of age. In all age groups and in both forms of time estimation (except verbal estimation in 10--12 years old children) there was a significant connection between the interval estimation and the type of activity. In adults and in 7--8 years old children, the connection was significantly tighter in operative estimations than in verbal ones. Unlike senior school children and adults, in 7--12 years old children there were sharp differences in precision between operative and verbal estimations and a discordance of their changes under the influence of activity. Precision and variability were rather similar in all age groups. It is suggested that the obtained data show heterochronity and a different rate of development of the higher nervous activity mechanisms providing for reflection of time in the form of verbal and voluntary motor reactions to the given interval.

BACKGROUND: Reduction in muscle strength is strongly associated with functional decline in women, and women with lower quadriceps strength adjusted for body weight are more likely to develop knee osteoarthritis. OBJECTIVE: To compare body weight--adjusted strength among women of different age/racial groups. STUDY DESIGN: Cross-sectional study of muscle strength in 918 women aged 20--83 (M ± SD = 52 ± 13). METHODS: An orthopedic examination was conducted including measurement of handgrip and lower extremity strength (hip abductors/external rotators, knee flexors/extensors). Data were grouped into young (20--39 years, n = 139), middle (40--54 years, n = 300), and older (55+ years, n = 424) ages for white (n = 699) and African American (AA) (n = 164) women. Means and standard deviations for strength adjusted for body weight were calculated for each age and racial group and compared using 2-way multivariate analysis of variance and post hoc tests. RESULTS: No significant age-by-race interaction (P = .092) but significant main effects for age and race (P < .001). Pairwise comparisons revealed significant differences in knee extensor and flexor strength between all age groups. For grip and hip external rotator strength, significant differences were found between the middle and older groups. Differences in hip abductor strength were found between the young and middle-aged groups. AA women had lower strength than white women in all muscle groups (P < .05) except hip external rotators. CONCLUSIONS: Strength decreased with age in all muscle groups but magnitude of decrease varied by muscle. Strengthening programs should target different muscles, depending on a woman's age and race.
Oral health-related quality of life in Dutch children with cleft lip and/or palate.
Bos, Annemieke; Prahl, Charlotte

To investigate the oral health-related quality of life (OH-RQoL) of Dutch cleft lip and palate patients. It was hypothesized that (1) there is no difference between cleft patients' and their parents' reports of patients' OH-RQoL; (2) there are no gender differences; (3) there are no differences in OH-RQoL between cleft patients with regard to their symptoms; and (4) there is no difference between patients above and below 12 years of age. The sample consisted of 122 patients with clefts (age range, 8-15 years) and their parents. Respondents were recruited from the cleft palate team of Amsterdam. They completed the Child Oral Health-Related Quality of Life questionnaire (COHIP). Items were divided into five different subscales, and scores on all subscales were compared between and within groups. Patients' and parents' perceptions differed significantly on three of the five subscales. Girls and boys did not differ significantly with regard to their perception of reported OH-RQoL. The cleft lip and cleft lip and alveolus [CL(A)] subgroup scored significantly higher on the functional well-being subscale. The cleft patients aged 12 years and older scored significantly lower on the emotional well-being and oral symptoms subscales when compared with their younger peers. Only the second hypothesis was not rejected in this study. This means that parents are not interchangeable with regard to reporting on their children's perceptions related to OH-RQoL, that OH-RQoL changes with age, and that it is important that subgroups are respected when investigating OH-RQoL in cleft patients.

The assessment of clinical competence and the impact of training in ambulatory settings are two issues of importance in the evaluation of medical student performance. This study compares the clinical skills performance of students placed in three types of community preceptors' offices (pediatrics, medicine, family medicine) on yearly clinical skills assessments with standardized patients. Our goal was to see if the site specialty impacted on clinical performance. The students in the study were completing a 3-year continuity preceptorship at a site representing one of the disciplines. Their performance on the four clinical skills assessments was compared. There was no significant difference in history taking, physical exam, communication, or clinical reasoning in any year (ANOVA p< or = .05) There was a small but significant difference in performance on a measure of interpersonal and interviewing skills during Years 1 and 2. The site specialty of an early clinical experience does not have a significant impact on performance of most of the skills measured by the assessments.

This study examined age and gender differences in physical activity levels and various physical activity patterns of 11-14-year-old Turkish adolescents and also determined if these differ between genders. Six hundred and fifty girls and 666 boys between the ages of 11 and 14 years constituted the sample of this study. Participants self-reported physical activity levels and patterns were determined by a Weekly Activity Checklist. A 2 x 4 (Gender x Age) MANOVA revealed overall significant main effect of gender and age on the physical activity level of adolescents; however, gender x age interaction effect was not significant. The findings indicated an interaction effect was not significant. The findings indicated an age-related decline in physical activity level, an increase in participation in low activities, and a decrease in participation in moderate and vigorous activities in 11-14-year-old Turkish adolescents. In addition it was found that boys were more active than girls and participated more in moderate and vigorous activities.

This study examined the effects of daily physical activity level on health-related factors according to gender and identified age-specific differences among Korean adults. Using data from the Korea National Health and Nutrition Examination Survey VI (2014-2015), we selected adults aged 19-64 years who participated in both a health examination and health interview survey. The study included 6,457 participants 19-64 years of age (2,611 men, 3,846 women). Assessment of the differences in health-related factors according to age and physical activity in men and women by repeated two-way analysis of variance (ANOVA) revealed significant interaction effects on total cholesterol (TC) and triglyceride (TG) levels and diastolic blood pressure (DBP) in male participants, but there were no significant interaction effects for any health-related factors in female participants. The group of female participants aged 40-64 years with daily physical activity levels over 200 kcal showed a significantly increased prevalence of 46% for dyslipidemia compared to that in female participants with daily physical activity levels below 200 kcal. Physical activity was positively correlated with weight and high-density lipoprotein cholesterol (HDL-C) levels in men 19-39 years of age, compared to weight, waist circumference (WC), body mass index (BMI), and DBP in men 40-64 years of age, and weight, WC, BMI, glycated hemoglobin (HbA1c) and triglyceride (TG) levels in women 19-39 years of age. In women 40- 64 years of age, physical activity was especially significantly positively correlated with weight, BMI, HDL-C and negatively correlated with fasting glucose and TG levels. In male and female participants, the 40-64-year age group showed negative results for health-related factors compared to those in the 19-39-year age group. The higher the weight, WC, BMI, the higher is the physical activity level. Physical activity levels were significantly positively correlated with health-related variables. ©2017 The Korean Society for Exercise Nutrition

This descriptive epidemiological study included 615 subjects investigated by their family doctor in the interval October 2011- August 2012. Patients were selected according to 2012 IDF diagnostic criteria resulting 304 patients. There was a Gaussian distribution of waist circumference (WC) with a maximum in age-group 70-80 years (46.3%), followed by age- groups 50-60 years (37.8%) and 60-70 years (41.6%). Waist circumference measurement showed an average of 100.76 +/- 11.59 cm, ranges 72 cm - 134 cm, without statistical significance. Mean body mass index (BMI) was 28.25 +/- 4.72 kg/m2 vs. 27.79 +/- 4.48 kg/m2. The difference is statistically significant (p = 0.05). Considering categorical the patients with hypertension (AHT) according to the definition, we found that only 7 cases did not have AHT (4.4%) as compared to a prevalence of AHT of 13.7% in the MS (metabolic syndrome) group. Mean serum triglyceride level was 123.11 +/- 68.55 mg/dl versus 113.75 +/- 65.62 mg/dl in the MS group, significantly higher (p < 0.003). Mean HDL cholesterol was 57.58 +/- 17.11 mg/dl versus 58.54 +/- 15.02 mg/dl, statistically significant difference (p < 0.05). The prevalence of glucoregulation disorders is higher in the MS group. Proportional relationships were found between BMI, WC, and SBP and high blood glucose. Comparison of blood glucose levels at baseline and at 1 year follow up showed significant differences.

Suicides may be misclassified as accidental deaths in countries with strict legal definitions of suicide, with cultural and religious factors leading to poor registration of suicide and stigma attached to suicide. The concordance between four different definitions of suicides was evaluated by examining the relationship between pure suicide and accidental death rates, gender differences, age-associated trends and potential distil risk and protective factors by conducting secondary analysis of the latest World Health Organisation data on elderly death rates. The four definitions of suicide were: (i) one-year pure suicides rates; one-year combined suicide rates (pure suicide rates combined with accidental death rates); (iii) five-year average pure suicide rates; and (iv) five-year average combined suicides rates (pure suicides rates combined with accidental death rates). The predicted negative correlation between pure suicide and accidental death rates was not observed. Gender differences were similar for all four definitions of suicide. There was a highly significant concordance for the findings of age-associated trends between one-year pure and combined suicide rates, one-year and five-year average pure suicide rates, and five-year average pure and combined suicide rates. There was poor concordance between pure and combined suicide rates for both one-year and five-year average data for the 14 potential distil risk and protective factors, but this concordance between one-year and five-year average pure suicide rates was highly significant. The use of one-year pure suicide rates in cross-national ecological studies examining gender differences, age-associated trends and potential distil risk and protective factors is likely to be practical, pragmatic and resource-efficient.
Effects of the Affordable Care Act on Young Women With Gynecologic Cancers.
Smith, Anna Jo Bodurtha; Fader, Amanda N
2018-06-01
To evaluate the effects of the dependent coverage mandate of the 2010 Affordable Care Act (ACA) on insurance status, stage at diagnosis, and receipt of fertility-sparing treatment among young women with gynecologic cancer. We used a difference-in-differences design to assess insurance status, stage at diagnosis (stage I-II vs III-IV), and receipt of fertility-spearing treatment before and after the 2010 ACA among young women aged 21-26 years vs women aged 27-35 years. We used the National Cancer Database with the 2004-2009 surveys as the pre-ACA years and the 2011-2014 surveys as the post-ACA years. Women with uterine, cervical, ovarian, vulvar, or vaginal cancer were included. We analyzed outcomes for women overall and by cancer and insurance type, adjusting for race, nonrural area, and area-level household income and education level. A total of 1,912 gynecologic cancer cases pre-ACA and 2,059 post-ACA were identified for women aged 21-26 years vs 9,782 cases pre-ACA and 10,456 post-ACA for women aged 27-35 years. The ACA was associated with increased insurance (difference in differences 2.2%, 95% CI -4.0 to 0.1, P=.04) for young women aged 21-26 years vs women aged 27-35 years and with a significant improvement in early stage at cancer diagnosis (difference in differences 3.6%, 95% CI 0.4-6.9, P=.03) for women aged 21-26 years. Receipt of fertility-sparing treatment increased for women in both age groups post-ACA (P for trend=.004 for women aged 21-26 years and .001 for women aged 27-35 years); there was no significant difference in differences between age groups. Privately insured women were more likely to be diagnosed at an early stage and receive fertility-sparing treatment than publicly insured or uninsured women throughout the study period (P<.001). Under the ACA's dependent coverage mandate, young women with gynecologic cancer were more likely to be insured and diagnosed at an early stage of disease.

Many of the previous randomized trials comparing percutaneous coronary intervention (PCI) with coronary artery bypass grafting (CABG) in patients with multivessel coronary artery disease reported equivalent or better survival with CABG as compared with PCI at 5-year follow-up. However, 5-year follow-up might be too short to evaluate the true differences in long-term clinical outcomes between PCI and CABG. Among 8934 patients enrolled in the extended 10- to 14-year follow-up study of the CREDO-Kyoto registry cohort-1 (Coronary Revascularization Demonstrating Outcome study in Kyoto) conducted in the bare-metal stent era, 5152 (PCI: n=3490 and CABG: n=1662) patients had multivessel coronary artery disease without left main disease. Median follow-up duration was 11.2 (interquartile range: 10.2-12.2) years. The cumulative 10-year incidence of all-cause death was not significantly different between PCI and CABG (32.2% versus 31.7%; log-rank P=0.93). After adjusting for confounders, however, the mortality risk of PCI was significantly higher than that of CABG (hazard ratio, 1.19 [95% confidence interval, 1.02-1.39]; P=0.03). Within 5 years after the index procedure, the risk for all-cause death was significantly higher after PCI than after CABG (hazard ratio, 1.41; 95% CI, 1.12-1.79; P=0.004). By a landmark analysis at 5 years, however, the cumulative 10-year incidence of and adjusted risk for all-cause death beyond 5 years were not significantly different between PCI and CABG (19.3% versus 20.0%; log-rank P=0.22 and hazard ratio, 1.02, 95% confidence interval, 0.83-1.26; P=0.82). CABG as compared with PCI was associated with better 10-year survival in patients with multivessel coronary artery disease. However, the benefit of CABG compared with PCI on late mortality beyond 5 years was not observed in this study. © 2016 American Heart Association, Inc.

For the first time, the development of paw preferences in the domestic cat, Felis silvestris catus, is explored. Twelve cats were tested at ages 12 weeks, 6 months, and 1 year on a challenge requiring them to use one of their paws to retrieve food. To control for repeated testing of the same cats at different ages, the subjects' paw preferences were compared with those of cats tested just once, at 6 months (n = 11) or 1 year (n = 14) of age. Analysis revealed a significant effect of age on the distribution of cats' paw preferences. Cats were significantly more likely to be ambilateral than paw preferent at 12 weeks and at 6 months but more likely to display a lateral bias in paw use at 1 year. There was a significant positive correlation between cats' paw preferences at 6 months and at 1 year. Lateralized behavior was strongly sex related. Females had a greater preference for using their right paw; males were significantly more inclined to adopt their left. Analysis revealed no significant difference in the direction or strength of paw preferences of cats tested longitudinally or cross-sectionally at 6 months or 1 year of age. Findings indicate that cats develop paw preferences by 1 year and hint at a relative stability in preferred paw use over time. The strong sex effect observed strengthens the case for the influence of a biological mechanism in the emergence of motor asymmetry in cats.

This study was designed to compare the Intelligence Quotient (IQ) among 3 to 7-year-old strabismic and nonstrabismic children in an Iranian population. In this cross-sectional study, 108 preschool children with equal numbers of strabismic/non-strabismic disorder (age 3-7 years) were randomly selected from exceptional strabismus clinics of Ahvaz and were evaluated with the preschool and primary scale of intelligence versions of Wechsler (WPPSI). In the current study, 108 children were evaluated. In strabismic patients the mean performance, verbal and total IQ were 89.46±19.79, 89.57±21.57 and 91.54±22.08 respectively.These mean scores in normal children were 91.89±47.53 , 87.56±15.6 and 89.96±17.62 consecuently. The results showed that these three different IQ subscales were not significantly different among 3 to 7 years old strabismic and nonstrabismic children ((P>0.05 for all comparisons). There was no significant difference in IQ between two sexes (P>0.05) while Persian tribe children had greater IQ score compared to other tribes (P<0.05). Also, higher paternal educational status of children related to higher IQ score. IQ score was better in combined deviations and was higher in exotropes than esotropes; however, these differences were not statistically significant.(p>0.05) In this evaluation, we did not found a significant negative interference of strabismus on IQ score of preschool children. It can be concluded that paternal educational level and tribe have a significant effect on intelligent quotient, while this is not the case on sex and ocular deviation.

Fifty-nine Melanesian (MF) and 39 Indian (IF) Fijian full-term newborns were studied within 5 days of birth. Dimensions recorded included birthweight, length, crown-rump length, head circumference, upper limb length, bycondylar humeral and femoral diameters and four skinfolds (triceps, subscapular, suprailiac and thigh). Data from previous pregnancies of the presenting newborns' mothers were added to presenting birthweights, giving a total of 160 MF and 84 IF birthweights. In all birthweight and linear dimensions MFs were the bigger. Sex differences were significant in respect only of head circumference and the two bicondylar diameters. Multiple regression analysis showed dimensions in MF newborns to have few significant relationships with the maternal and socio-economic variables of age, parity, stature and years of education, but IFs had many more significant relationships. When covariance correction was made for the significant maternal and socio-economic variables (maternal age and parity) little effect on racial differences was seen. All linear dimensions except length could be subsumed into birthweight. MFs had greater triceps and subscapular skinfold thicknesses than IFs, a difference which was not much changed by covariance correction for significant maternal and socio-economic variables (maternal stature and years of education). Measurements of shape, expressed as ratios of linear dimensions, showed few racial differences but males had relatively broader limbs. For upper limb shape only, this difference was maintained after covariance correction for significant maternal and socio-economic variables (parity, stature and education). The greater size of MF infants at birth is associated with lower peri- and neonatal death rates. However this advantage is reversed during the remainder of the first year of life. It is suggested that better standards of infant care among IFs are responsible for this change.

The purposes of this study were (1) determine if youth peak Achilles tendon (AT) strain, peak AT stress, and AT stiffness, measured during an isometric plantar flexion, differed after six months (mos) of growth, and (2) determine if sex, physical activity level (Physical Activity Questionnaire (PAQ-C)), and/or growth rate (GR) were related to these properties. AT stress, strain, and stiffness were quantified in 20 boys (13.47±0.81 years) and 22 girls (11.18±0.82 years) at 2 times (0 and 6 mos). GR (change in height in 6 mos) was not significantly different between boys and girls (3.5±1.4 and 3.4±1.1cm/6 mos respectively). Peak AT strain and stiffness (mean 3.8±0.4% and 128.9±153.6N/mm, respectively) did not differ between testing sessions or sex. Peak AT stress (22.1±2.4 and 24.0±2.1MPa at 0 and 6 mos, respectively) did not differ between sex and increased significantly at 6 mos due to a significant decrease in AT cross-sectional area (40.6±1.3 and 38.1±1.6mm(2) at 0 and 6 mos, respectively) with no significant difference in peak AT force (882.3±93.9 and 900.3± 65.5N at 0 and 6 mos, respectively). Peak AT stress was significantly greater in subjects with greater PAQ-C scores (9.1% increase with 1 unit increase in PAQ-C score) and smaller in subjects with faster GRs (13.8% decrease with 1cm/6 mos increase in GR). These results indicate that of the AT mechanical properties quantified, none differed between sex, and only peak AT stress significantly differed after 6 months and was related to GR and physical activity.

To examine racial differences in employment status and occupational status 1 year after a traumatic brain injury (TBI). Retrospective study. Longitudinal dataset of the Traumatic Brain Injury Model Systems national database. Subjects with primarily moderate to severe TBI (3468 whites vs 1791 minorities) hospitalized between 1989 and 2005. Not applicable. Employment status (competitively employed or unemployed) and occupational status (professional/managerial, skilled, or manual labor) at 1 year postinjury. Race and/or ethnicity has a significant effect on employment status at 1 year postinjury (chi(1)(2)=58.23, P<.001), after adjusting for preinjury employment status, sex, Disability Rating Scale at discharge, marital status, cause of injury, age, and education. The adjusted odds of being unemployed versus competitively employed are 2.17 times (95% confidence interval, 1.78-2.65) greater for minorities than for whites. Race and ethnicity does not have a significant effect on occupational status at 1 year postinjury. With this empirical evidence supporting racial differences in employment outcomes between minorities and whites at 1 year postinjury, priority should be given to tailoring interventions to maximize minority survivors' work-related productivity.

We estimated the effect of the ACA expansion of dependents' coverage on health care expenditures and utilization for young adults by race/ethnicity. We used difference-in-difference models to estimate the impact of the ACA expansion on health care expenditures, out-of-pocket payments (OOP) as a share of total health care expenditure, and utilization among young adults aged 19 to 26 years by race/ethnicity (White, African American, Latino, and other racial/ethnic groups), with adults aged 27 to 30 years as the control group. In 2011 and 2012, White and African American young adults aged 19 to 26 years had significantly lower total health care spending compared with the 27 to 30 years cohort. OOP, as a share of health care expenditure, remained the same after the ACA expansion for all race/ethnicity groups. Changes in utilization following the ACA expansion among all racial/ethnic groups for those aged 19 to 26 years were not significant. Our study showed that the impact of the ACA expansion on health care expenditures differed by race/ethnicity.

To assess the association between visible third molars and the prevalence of periodontal inflammatory disease of non-third molars. Subjects aged 14 to 45 years with 4 asymptomatic third molars were enrolled in an institutional review board-approved study. Subjects were classified based on whether at least 1 third molar was visible or all third molars were not visible. Full-mouth periodontal probing depth (PD) data, with 6 sites per tooth, were obtained as a measure of a subject's periodontal status. At least 1 non-third molar PD of 4 mm or greater was indicative of periodontal inflammatory disease. Outcomes for the respective groups were compared by use of Cochran-Mantel-Haenszel row mean score statistics. The level of significance for differences was set at .05. The 342 subjects in the visible group were significantly older, with a median age of 26 years (interquartile range, 22.4-32.2 years), as compared with the 69 subjects in the not visible group, with a median age of 21 years (interquartile range, 18.8-24.9 years) (P < .01). The proportion of males and females was not statistically different between groups (P > .05). Most subjects were white. Significantly more subjects with at least a college education were in the visible group than in the not visible group (P < .01). The rate of tobacco use was low and did not differ between groups. Subjects in the visible group were significantly more likely to have at least 1 PD of 4 mm or greater on non-third molars than those in the not visible group: 59% versus 35%. In both groups, first/second molars were more affected than nonmolars when we controlled for differences in age between groups. The visible presence of third molars in adolescents and young adults was significantly associated with periodontal inflammatory disease of non-third molars.

This study aimed to investigate the relationship between persistent human papillomavirus (HPV) infection and cervical lesion. Clinical data of 16,320 patients who visited our clinic between January 2009 and December 2013 were collected. Retrospective analysis was performed to analyze the overall HPV infection and compare the infection rates of different subtypes among different age groups, to reveal the relationship between persistent HPV infection and cervical cytology. The overall prevalence of HPV was 26.54%. The most common genotypes were HPV 52, HPV 16, HPV 58, CP8304, and HPV 53. The highest overall high-risk HPV prevalence was found in women older than 60 years, and the lowest prevalence was found in women between the ages of 30 and 39 years. There was no significant difference in low-risk HPV prevalence among different age groups (p = .693). The HPV clearance rate after 1 year among those with initial positive test was 87.65%. The constituent ratios of high- or low-risk HPV subtypes were not significantly different (p = .545) between nonpersistent-positive and persistent-positive (PP) groups. Conversely, the constituent ratios of singe- or multi-type HPV infection were significantly different (p < .05) between these 2 groups. The most common subtypes in PP group were HPV 16, 52, 58, CP8304, and 33. The occurrence rates of atypical squamous cells of undetermined significance, high-grade squamous intraepithelial lesion, and squamous cell carcinoma in the PP group significantly increased (p < .05). Persistent HPV infections are mainly caused by multiple types of HPV and high-risk HPV. Our region should particularly pay attention to the prevention and treatment of HPV 16, 52, and 58.

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

Abstract Background: The effects of age and speed on foot and ankle kinematics in gait studies using foot models are not fully understood, whereas this can have significant influence. We analyzed these variables with the 4-segment Oxford foot model. Methods: Twenty-one healthy subjects (aged 20–65 years) were recruited for gait analysis. The effect of speed on foot and ankle kinematics was assessed by comparing results during slow walking and fast walking. To assess the effect of age, a group of 13 healthy young adults (aged 20–24 years) were compared with a group of 8 older adults (aged 53–65 years). Also, the interaction between age and speed was analyzed. Results: Regarding speed, there was a significant difference between forefoot/hindfoot motion in the sagittal plane (flexion/extension) during both loading- and push-off phase (P = .004, P < .001). Between hindfoot/tibia, there was a significant difference for all parameters except for motion in the sagittal plane (flexion/extension) during push-off phase (P = .5). Age did not significantly influence kinematics. There was no interaction between age and speed. Conclusion: Our analysis found that speed significantly influenced the kinematic outcome parameters. This was more pronounced in the ankle joint. In contrast, no significant differences were found between younger and older healthy subjects. PMID:28858109

We compared differences in intelligence and memory function between normal elderly Japanese subjects with more years of education and those with fewer years of education. We also investigated clinical and neuropsychological factors that are strongly correlated with memory function. There were 118 normal elderly subjects who underwent the Mini-Mental State Examination, Wechsler Adult Intelligence Scale, 3rd edition (WAIS-III), and Wechsler Memory Scale Revised. Subjects with at least 13 years of education were categorized as the H group, and those with 12 years of education or less were categorized as the L group. Age and Mini-Mental State Examination scores were not significantly different between the two groups. On the WAIS-III, there were significant differences between the two groups in Verbal IQ and Full Scale IQ. On the Wechsler Memory Scale Revised, there were significant differences between the two groups in Visual Memory, General Memory, and Delayed Recall. Correlation coefficients between memory function and the other factors demonstrated significant but weak correlations between years of education and General Memory (R = 0.22) and between years of education and Delayed Recall (R = 0.20). Strong correlations were found between Verbal IQ and Verbal Memory (R = 0.45), between Verbal IQ and General Memory (R = 0.49), between Full Scale IQ and General Memory (R = 0.50) and between Full Scale IQ and Delayed Recall (R = 0.48). In normal elderly Japanese subjects, years of education weakly correlated with memory function while Verbal IQ, Full Scale IQ and Verbal Comprehension on WAIS-III had stronger correlations with memory function. Verbal IQ and Verbal Comprehension on WAIS-III were found to be insusceptible to the cognitive decline characteristic of Alzheimer's disease or amnestic mild cognitive impairment. Therefore, verbal intelligence, as measured by Verbal IQ and Verbal Comprehension, may be the most useful factor for inferring premorbid memory function in Alzheimer's disease or amnestic mild cognitive impairment patients. © 2013 The Authors.

Agriculture is one of the several major sources of nitrate pollution, and therefore the EU Nitrate Directive, designed to decrease pollution, has been implemented. Point sources like septic systems and broken sewage systems also contribute to water pollution. Pollution of groundwater by nitrate from 19 shallow wells was studied in a typical agricultural region, middle Podravina, in northwest Croatia. The concentration of nitrate ranged from <0.1 to 367 mg/l in water from wells, and 29.8 % of 253 total samples were above maximum acceptable value of 50 mg/l (MAV). Among regions R1-R6, there was no statistically significant difference in nitrate concentrations ( F = 1.98; p = 0.15) during the years 2002-2007. Average concentrations of nitrate in all 19 wells for all the analyzed years were between recommended limit value of 25 mg/l (RLV) and MAV except in 2002 (concentration was under RLV). The results of the repeated measures ANOVA showed statistically significant differences between the wells at the point source distance (proximity) of <10 m, compared to the wells at the point source distance of >20 m ( F = 10.6; p < 0.001). Average annual concentrations of nitrate during the years studied are not statistically different, but interaction between proximity and years is statistically significant ( F = 2.07; p = 0.04). Results of k-means clustering confirmed division into four clusters according to the pollution. Principal component analysis showed that there is only one significant factor, proximity, which explains 91.6 % of the total variability of nitrate. Differences in water quality were found as a result of different environmental factors. These results will contribute to the implementation of the Nitrate Directive in Croatia and the EU.

Objective To investigate how individual risk factors for cardiovascular disease (CVD) (blood pressure, lipid levels, body mass index, waist and hip circumference, use of antihypertensive or hypolipidemic medication, and diagnosed diabetes) differ in people aged 46 years with different smoking behaviour and history. Methods This population-based cohort study is based on longitudinal data from the Northern Finland Birth Cohort 1966 project. Data were collected at the 31-year and 46-year follow-ups, when a total of 5038 and 5974 individuals participated in clinical examinations and questionnaires. Data from both follow-ups were available for 3548 participants. In addition to individual CVD risk factors, Framingham and Systematic Coronary Risk Evaluation (SCORE) algorithms were used to assess the absolute risk of a CVD event within the next decade. Results The differences in individual risk factors for CVD reached statistical significance for some groups, but the differences were not consistent or clinically significant. There were no clinically significant differences in CVD risk as measured by Framingham or SCORE algorithms between never smokers, recent quitters and former smokers (7.5%, 7.4%, 8.1% for men; 3.3%, 3.0%, 3.2% for women; p<0.001). Conclusions The effect of past or present smoking on individual CVD risk parameters such as blood pressure and cholesterol seems to be of clinically minor significance in people aged 46 years. In other words, smoking seems to be above all an independent risk factor for CVD in the working-age population. Quitting smoking in working age may thus reduce calculated CVD risk nearly to the same level with people who have never smoked. PMID:27493759

Objective To explore age differences in factors associated with positive sexually transmitted diseases (STD) status among a sample of African-American adolescent females. Methods Data were collected via ACASI from 701 African-American adolescent females (14–20 years) seeking services at reproductive health clinics. Adolescents provided self-collected vaginal swabs assayed using NAAT to assess the prevalence of three STDs. Results Younger adolescents (14–17 years) had significantly higher rates of STDs than older adolescents (18–20 years), but older adolescents had significantly higher levels of STD-associated risk behavior. In controlled analysis, having a casual sex partner was the only variable significantly associated with a positive STD test for younger adolescents, and prior history of STD and higher impulsivity were significantly associated with testing STD positive among older adolescents. Conclusions These findings suggest that developmentally tailored STD/HIV prevention interventions are needed for younger and older subgroups of adolescent females to help reduce their risk of infection.

The authors' aim was to find the features of balance, proprioception, and gross motor development of Chinese children 3-6 years old and their correlations, provide theoretical support for promoting children's motor development, and enrich the world theoretical system of motor development. This study used a Tekscan foot pressure measurement instrument (Tekscan, Inc., Boston, MA), walking on a balance beam, Xsens 3-dimensional positional measuring system (Xsens Technologies, Enschede, the Netherlands), and Test of Gross Motor Development-2 to assess static balance, dynamic balance, knee proprioception, and levels of gross motor development (GMD) of 3- to 6-year-old children (n = 60) in Beijing. The results are as follows: children had significant age differences in static balance, dynamic balance, proprioception, and levels of GMD; children had significant gender differences in static balance, proprioception, and levels of GMD; children's static balance, dynamic balance, and proprioception had a very significant positive correlation with GMD (p < .01), but no significant correlation with body mass index.

To estimate differences in skeletal maturity and stature from birth to age 18 years between individuals who are overweight vs normal weight in young adulthood. Weight, length and height, and relative skeletal age (skeletal-chronological age) were assessed annually from birth to age 18 years in 521 subjects (255 women) in the Fels Longitudinal Study who were overweight or obese (body mass index (BMI) >25 kg m(-2), n=131) or normal weight (n=390) in young adulthood (18-30 years). Generalized estimating equations were used to test for skeletal maturity and stature differences by young adult BMI status. Differences in height increased during puberty, being significant for girls at ages 10 to 12 years, and for boys at ages 11 to 13 years (P-values<0.001), with overweight or obese adults being ∼3 cm taller at those ages than normal weight adults. These differences then diminished so that by age 18 years, overweight or obese adults were not significantly different in stature to their normal weight peers. Differences in skeletal maturity were similar, but more pervasive; overweight or obese adults were more skeletally advanced throughout childhood. Skeletal maturity differences peaked at chronological age 12 in boys and 14 in girls (P-values<0.001), with overweight or obese adults being ∼1 year more advanced than normal weight adults. This descriptive study is the first to track advanced skeletal maturity and linear growth acceleration throughout infancy, childhood and adolescence in individuals who become overweight, showing that differences occur primarily around the time of the pubertal growth spurt. Increased BMI in children on a path to becoming overweight adults precedes an advancement in skeletal development and subsequently tall stature during puberty. Further work is required to assess the predictive value of accelerated pubertal height growth for assessing obesity risk in a variety of populations.

Objective To investigate antecedents of Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms in children born extremely preterm (EP; <26 weeks gestation). Method The EPICure Study recruited all babies born EP in the UK and Ireland in March-December 1995. Neurodevelopmental outcomes were assessed at 2.5 (n=283; 90%), 6 (n=160; 78%) and 11 (n=219; 71%) years of age. Parents and teachers completed the Du Paul Rating Scale-IV to assess inattention and hyperactivity/impulsivity symptoms at 11 years. Regression analyses were used to explore the association of neonatal, neurodevelopmental and behavioral outcomes to 6 years with ADHD symptoms at 11 years. Results EP children had significantly more inattention (mean difference 1.2 SD; 95% CI 0.9, 1.5) and hyperactivity/impulsivity (0.5 SD; 0.2, 0.7) than controls, with a significantly greater effect size for inattention than hyperactivity/impulsivity. Significant independent predictors of inattention at 11 years included smaller head circumference, lower IQ and pervasive peer relationship problems at 6 years, and motor development at 2.5 years. In contrast, significant independent predictors of hyperactivity/impulsivity included lower IQ, pervasive conduct problems and ADHD symptoms at 6 years, externalizing problems at 2.5 years and non-white maternal ethnicity. Conclusions EP children are at increased risk for ADHD symptoms, predominantly inattention, for which the antecedents differ by symptom domain. Attention deficits following EP birth were associated with poor brain growth and neurological function. Cognitive and behavioral assessments in early and middle childhood to identify neurodevelopmental and peer relationship problems may be beneficial for identifying EP children at risk for inattention.

To delineate the effect of chronic electromagnetic field (EMF) exposure from radar on plasma melatonin and serotonin levels in occupationally exposed military personnel. A total of 166 male military personnel participated in the study out of which only 155 joined for blood draw. They were divided into three sets: Control group (n = 68), exposure group I (n = 40) exposed to 8-12 GHz and exposure group II (n = 58) working with radar at 12.5-18 GHz frequency. The three groups were further split into two groups according to their years of service (up to 10 years and > 10 years) in order to investigate the effect of years of exposure from radar. Melatonin and serotonin levels were estimated by enzyme immunoassay in fasting blood samples collected from 06:00-07:00 h. EMF measurements were recorded at different locations using Satimo EME Guard 'Personal Exposure Meter' and Narda 'Broad Band Field Meter'. The group I exposed population registered a minor though not significant decrease in plasma melatonin concentration while the other group II exposed population registered statistically significant decline in melatonin concentration when compared with controls. Highly significant increase in plasma serotonin levels was found in exposure group II when compared to control whereas marginal non-significant rise was also registered in exposure group I in comparison to control. Exposure in terms of length of service up to 10 years did not produce any significant effect in the indoleamine levels in both the exposure groups when they were compared with their respective control groups. Whereas, length of service greater than 10 years was observed to decrease and increase respectively the melatonin and serotonin concentration significantly in exposure group II but not in exposure group I. However, correlation test did not yield any significant association between years of service and melatonin or serotonin levels respectively in both the exposure sets I and II. No significant association was observed between melatonin and serotonin levels as well. The study showed the EMF ability to influence plasma melatonin and serotonin concentration in radar workers, significantly in 12.5-18 GHz range with service period greater than 10 years.

To explore whether the implementation of performance-based contracting (PBC) within the State of Maine’s substance abuse treatment system resulted in improved performance, one descriptive and two empirical analyses were conducted. The first analysis examined utilization and payment structure. The second study was designed to examine whether timeliness of access to outpatient (OP) and intensive outpatient (IOP) substance abuse assessments and treatment, measures that only became available after the implementation of PBC, differed between PBC and non-PBC agencies in the year following implementation of PBC. Using treatment admission records from the state treatment data system (N=9,128), logistic regression models run using generalized equation estimation techniques found no significant difference between PBC agencies and other agencies on timeliness of access to assessments or treatment, for both OP and IOP services. The third analysis, conducted using discharge data from the years prior to and after the implementation of performance-based contracting (N=6,740) for those agencies that became a part of the performance-based contracting system, was designed to assess differences in level of participation, retention, and completion of treatment. Regression models suggest that performance on OP client engagement and retention measures was significantly poorer the year after the implementation of PBC, but that temporal rather than a PBC effects were more significant. No differences were found between years for IOP level of participation or completion of treatment measures. PMID:21249461

To determine whether raters' first impressions of youth with craniofacial differences are modifiable. Observational study of the association between first impressions and social skills as related to youth aged 11 to 18 years with craniofacial differences. University research offices and clinics. Youth aged 11 to 18 years with (n = 29) and without (n = 31) craniofacial differences; adults (n = 40), dental/medical students (n = 46), and education students (n = 29), all without craniofacial differences. Participants were recruited from medical clinics and through community advertising at all three study sites. The First Impressions Rating Scale. After viewing 1-minute portrayals of positive social skills by actors with craniofacial differences, raters' perceptions moved significantly in the positive direction for all 26 attributes on the First Impressions Rating Scale; whereas, after viewing negative social skills, ratings moved significantly in the negative direction for 25 of 26 First Impressions Rating Scale attributes. It appears that first impressions others have of youth with craniofacial differences are significantly affected by how these youth present themselves in social situations, suggesting that positive social skills may help reduce the amount of stigma that youth with craniofacial differences encounter.

Background: Recognition, diagnosis, and treatment of athletic pubalgia (AP), also known as sports hernia, once underrecognized and undertreated in professional football, are becoming more common. Surgery as the final treatment for sports hernia when nonsurgical treatment fails remains controversial. Given the money involved and popularity of the National Football League (NFL), it is important to understand surgical outcomes in this patient population. Hypothesis: After AP surgery, players would: (1) return to sport (RTS) at a greater than 90% rate, (2) play fewer games for fewer years than matched controls, (3) have no difference in performance compared with before AP surgery, and (4) have no difference in performance versus matched controls. Study Design: Cohort study; Level of evidence, 3. Methods: Internet-based injury reports identified players who underwent AP surgery from January 1996 to August 2015. Demographic and performance data were collected for each player. A 1:1 matched control group and an index year analog were identified. Control and case performance scores were calculated using a standardized scoring system. Groups were compared using paired Student t tests. Results: Fifty-six NFL players (57 AP surgeries) were analyzed (mean age, 28.2 ± 3.1 years; mean years in NFL at surgery, 5.4 ± 3.2). Fifty-three players were able to RTS. Controls were in the NFL longer (P < .05) than players who underwent AP surgery (3.8 ± 2.4 vs 3.2 ± 2.1 years). Controls played more games per season (P < .05) than post-AP players (14.0 ± 2.3 vs 12.0 ± 3.4 games per season). There was no significant (P > .05) difference in pre- versus post-AP surgery performance scores and no significant (P > .05) difference in postoperative performance scores versus controls post-index. Conclusion: There was a high RTS rate after AP surgery without a significant difference in postoperative performance, though career length and games per season after AP surgery were significantly less than that of matched controls.

The contents of fructose and citric acid in the semen of seven bulls of different ages were examined over a one-year period. The bulls were used as sires in the Artificial Insemination Station. The semen production was within the normal range. In the course of the investigations the temperature and moisture regimes of the air in the barns was optimal for the semen production of the bulls. No statistically significant changes in the amount of fructose and citric acid were established at different average diurnal temperatures and the relative moisture content in the different annual seasons. A marked positive correlation (r = 0.070 +/- 0.04) was observed between the changes in the contents of fructose and citric acid throughout the year. These changes were in an inverse correlation with the number of spermatozoa per mL of semen (r = 0.26 +/- 0.08) and in a moderate one for the citric acid (r = 0.49 +/- 0.06). In the bulls of the Red Dannish cattle there was a statistically significant decrease in the number of spermatozoa and a statistically significant increase in the number of immobile spermatozoa in the winter season.

Anthropometric data can be used to identify the physical dimensions of equipment, furniture, clothing and workstations. The use of poorly designed furniture that fails to fulfil the users' anthropometric dimensions, has a negative impact on human health. In this study, we measured some anthropometric dimensions of Iranian children from different ethnicities. A total of 12,731 Iranian primary school children aged 7-11 years were included in the study and their static anthropometric dimensions were measured. Descriptive statistics such as mean, standard deviation and key percentiles were calculated. All dimensions were compared among different ethnicities and different genders. This study showed significant differences in a set of 22 anthropometric dimensions with regard to gender, age and ethnicity. Turk boys and Arab girls were larger than their contemporaries in different ages. According to the results of this study, difference between genders and among different ethnicities should be taken into account by designers and manufacturers of school furniture. In this study, we measured 22 static anthropometric dimensions of 12,731 Iranian primary school children aged 7-11 years from different ethnicities. Descriptive statistics such as mean, standard deviation and key percentiles were measured for each dimension. This study showed significant differences in a set of 22 anthropometric dimensions in different genders, ages and ethnicities.

Respiratory syncytial virus hospitalization (RSVH) rates in children <2 years of age with hemodynamically significant congenital heart disease (HSCHD) are 2- to 4-fold higher compared with healthy term infants. Pediatric recommendations differ as to whether palivizumab is beneficial beyond 1 year of age. The objective of this study was to determine whether differences exist in respiratory-related illness hospitalization (RIH) and RSVH in HSCHD infants receiving palivizumab during the first year versus second year of life in the Canadian Registry of Palivizumab. The Canadian Registry of Palivizumab is a prospective database of infants who received ≥1 dose of palivizumab in 32 hospitals from 2005 to 2015. Demographic data were collected at enrollment and RIH events recorded monthly. Infants <24 months of age with HSCHD were recruited. Of 1909 HSCHD infants, 1380 (72.3%) in the first year (mean age, 4.2 months) and 529 (27.7%) in the second year of life (mean age, 17.8 months) received prophylaxis. Baseline demographics for day-care attendance, multiple births, enrollment age and weight differed between the groups (all P < 0.05). Additionally, second year infants had a more complicated neonatal course, with significantly longer length of stay (51.2 vs. 24.9 days) compared with those in the first year. The RIH and RSVH rates in the first year were 11.2% and 2.3% and in the second year were 10.6% and 1.7%. Cox regression analysis showed similar hazard for RIH [hazard ratio, 1.9; 95% confidence interval: 0.7-4.6; P = 0.18] and RSVH [hazard ratio, 2.0; 95% confidence interval: 0.2-16.5; P = 0.52]. Infants in the first and second year of life had a similar RSVH hazard. These findings suggest that infants in the second year with HSCHD, who remain unstable, are equally at risk for RSVH and merit prophylaxis.

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

The aim of the present study was to define some cephalometric standards in a group of 217 Finnish girls from 7.0 to 18.0 years of age and furthermore to estimate the influence of the skeletal classes on these standards. Age-related changes were seen between the standards of the youngest (7.0-9.5 years) and the oldest (14.5-18.0 years) group where 9 out of 15 of the inspected angles increased with age, three of them ANPr***, SNPg** and SNB* significantly, and 6 decreased, four of them significantly: ANPg***, ANB**, NL/ML* and RL/ML*. The cranial base angles did not show any significant age-related or skeletal type-related variations. Between the skeletal groups I and II significant differences were seen in 11 variables. Between skeletal I and III groups, 7 angles were significantly different. The results demonstrate that when cephalometric standards are used, they should be derived from that population, they should be age related, and the skeletal pattern should be taken into account.

Successful brain aging in the oldest old (≥90 years) is underexplored. This study examined cross-sectional brain morphological differences from 8th to 11th decades of life in nondemented individuals by high-resolution magnetic resonance imaging. Two hundred seventy-seven nondemented community-dwelling participants (71-103 years) from Sydney Memory and Ageing Study and Sydney Centenarian Study comprised the sample, including a subsample of 160 cognitively high-functioning elders. Relationships between age and magnetic resonance imaging-derived measurements were studied using general linear models; and structural profiles of the ≥90 years were delineated. In full sample and the subsample, significant linear negative relationship of gray matter with age was found, with the greatest age effects in the medial temporal lobe and parietal and occipital cortices. This pattern was further confirmed by comparing directly the ≥90 years to the 71-89 years groups. Significant quadratic age effects on total white matter and white matter hyperintensities were observed. Our study demonstrated heterogeneous differences across brain regions between the oldest old and young old, with an emphasis on hippocampus, temporoposterior cortex, and white matter hyperintensities.

Factors responsible for the low incidence of clinical prostate cancer (3-8/100,000 men/year) in the Arab population remain unclear, but may be related to changes in steroid hormone metabolism. We compared the levels of serum conjugated and unconjugated steroids between Arab and Caucasian populations, to determine if these can provide a rational explanation for differences in incidence of prostate cancer between the two populations. Venous blood samples were obtained from 329 unselected apparently healthy indigenous Arab men (Kuwaitis and Omanis) aged 15-80 years. Samples were also obtained from similar Arab men with newly diagnosed prostate cancer or benign prostatic hyperplasia (BPH). The samples were taken between 8:00 am and 12:00 noon. Serum levels of total testosterone, (TT), sex hormone binding globulin (SHBG), free androgen index (FAI); adrenal C19-steroids, dehydroepiandrosterone sulphate (DHEAS) and androstenedione (ADT) were determined using Immulite kits (Diagnostic Systems Laboratories Inc, Webster Texas, USA). The results obtained in Arab men were compared with those reported for similarly aged Chinese, German and White USA men. In all four ethnic groups, median TT and FAI declined with age, while SHBG increased with age. However, the mean TT and SHBG was significantly lower (p < 0.01) and the FAI significantly higher in Arab men (p < 0.01) compared to German men only in 21-30 years age group. In the other age groups the levels of TT and SHBG were higher in the Germans but the differences were not statistically significant. In all the racial groups serum levels of DHEAS and ADT reached a peak by about 20 years of life, and then declined progressively. The mean DHEAS in American Caucasians aged 20-29 years was 11.4 micromol/l compared to 6.22 micromol/l in the Arabs (p < 0.001). The mean DHEAS in USA Caucasians aged 70-79 years was 2.5 micromol/l compared to 1.8 micromol/l (p < 0.03) in the Arabs. There was no significant difference in mean serum levels of DHEAS between German and USA men. Similarly, there was no significant difference in the level of the hormones between Arab and Chinese men. Arab men with newly diagnosed prostate cancer had high serum TT, SHBG and DHEAS compared to those without the disease. The mean TT and SHBG was significantly lower in Arab men compared to Caucasian men especially in early adulthood. Caucasians have significantly higher serum levels of the precursor androgens DHEAS and ADT especially in early adulthood compared to Arab men. These observations of low circulating androgens and their adrenal precursors in Arab men may partially account for the decreased risk for prostate cancer among Arab men.

The aim of this study was to examine clinically relevant data on four restorative procedures for non-carious cervical lesions using United States Public Health Service (USPHS)-compatible clinical and photographic criteria and to compare different methods of analyzing clinical data. Fourteen patients with at least one or two pairs of non-carious lesions under occlusion and a mean age of 50 were enrolled in this study. A total of 56 restorations (14 with each material) were placed by three experienced, calibrated dental practitioners. Two other experienced and calibrated practitioners, under single-blind conditions, followed up on all restorations for a period of one year. Three materials were randomly placed: a micro-hybrid composite with two polymerization methods (G1 and G2), a flowable micro-hydrid composite (G3), and a resin-modified glass ionomer (G4). Statistical analysis was performed using the Kruskall-Wallis test (p<0.05) and a Mann-Whitney U modified test with a corrected significance level. At the one year evaluation time, there were no restorations with secondary caries and the retention rates in G1 (IntenS with a hard polymerization), G2 (IntenS with a soft polymerization), G3 (Filtek flow), and G4 (Fuji II LC) were 85.7% (two losses), 92.8% (one loss), 100%, and 100%, respectively. The total visual comparison of the results at baseline (15 days later) showed significant differences only with the clinical acceptance criterion: G1 was different from G2, with a soft polymerization device (p<0.05). In terms of surface quality at one year, G1, G2, and G3 exhibited a statistically significant difference from G4, p<0.05. The digital analysis at baseline showed significant differences only with the clinical acceptance criterion: G1=G2 was different from G3=G4, p<0.05. At one year, only the microporosity criterion showed any statistical differences: G1=G2=G3 was different from G4, p<0.05. The resin-modified glass ionomer was easier to use and had a high retention rate, but it failed in terms of surface quality (visual mode) and porosity (digital mode) criteria compared to the others groups. Overall results showed no difference between groups G1 (hard-polymerized) and G2 (soft-polymerized), and only G1 was affected by the marginal edge (p<0.03) and integrity criteria (p<0.02) at one year.

Seasonal and interannual variability in temperature, precipitation and chemical resources may regulate fungal community structure in forests but the effect of such variability is still poorly understood. In this study, I examined changes in fungal communities over two years and how these changes were correlated to natural variation in soil conditions. Soil cores were collected every month for three years from permanent plots established in an old-growth hardwood forest, and molecular methods were used to detect fungal species. Species richness and diversity were not consistent between years with richness and diversity significantly affected by season in one year but significantly affected by depth in the other year. These differences were associated with variation in late winter snow cover. Fungal communities significantly varied by plot location, season and depth and differences were consistent between years but fungal species within the community were not consistent in their seasonality or in their preference for certain soil depths. Some fungal species, however, were found to be consistently correlated with soil chemistry across sampled years. These results suggest that fungal community changes reflect the behavior of the individual species within the community pool and how those species respond to local resource availability. © FEMS 2015.

Abstract The aim of this study was to analyze the effect of different small-sided and conditioning games (SSCG) with different tactical contents on heart rate responses, technical performance and collective organization of youth basketball players of different performance levels. Twenty male basketball players from U14 (13.7 ± 0.8 years old; 4.2 ± 1.4 years of practice) and U16 (15.3 ± 1.1 years old; 6.4 ± 2.1 years of practice) participated in this research study. The two-way MANOVA revealed that the sports level (p = 0.009; ηp2 = 0.151), format (p = 0.001; ηp2 = 0.246) and task condition (p = 0.023; ηp2 = 0.104; small effect size) had significant main effects on heart rate responses. It was also found that the format (p = 0.001; ηp2 = 0.182) had significant main effects on technical performance. A smaller format significantly increased the heart rate, volume of play, efficiency index and collective density during attacking plays. The SSCG with attacking content statistically increased the heart rate, efficiency index and performance score. Therefore, this study revealed that different SSCGs with tactical content influenced the physiological responses of youth players. PMID:28828085

Background Tuberculosis (TB) remains a major global health problem. The childhood tuberculosis has some unique features different which makes the diagnosis more complicated. Here we described the epidemiologic, clinical and microbiologic features of children with extra pulmonary and pulmonary TB. Methods The data of the patients <14 years with active TB were collected and compared in pulmonary (PTB) and extrapulmonary TB (EXPTB) patients. Results A total of 128 cases was included. Forty-two cases occurred in children were < 5 years of age; 41 cases between 6–10 years and 45 cases > 10 years. PTB was present in 75,0% of the cases, and EXPTB was present in 25% of cases. There was no significant difference between the EXPTB and PTB by means of distribution of age groups (p=0,201). The rate of patients free of constitutional symptoms were significantly higher in EXPTB compared to PTB(p=0,000). There was no significant difference between EXPTB and PTB by means of sources detection(p=0,069). Conclusion TB is still a major public health problem. EXPTB has an insidious and silent onset without any constitutional symptoms, and both microbiological confirmation and the source by an adult are not frequently found. Moreover, detection of the adult source is mandatory for controlling the TB disease in children PMID:25237471

Determining the efficacy of a life-skills' programme within the context of a school health promotion programme using teenagers from a high-school in the district of Huancavelica, Peru during school year 2006. This was non-equivalent experimental research with pre-test and post-test. The subjects consisted of 284 high school students. The variables analyzed were communication, self esteem, assertiveness, decision making, sex and age. There was a significant increase in the experimental group's communication and assertiveness skills' development. There were no significant differences in decision-making and self-esteem skills. The life-skills' programme was effective during one school year, especially in terms of learning and developing communication and assertiveness skills. However, self-esteem and decision-making skills did not present a statistically significance difference. Programme implementation must thus be redirected and the life-skills' programme should be implemented throughout all high-school years.

This test was administered to a sample of 314 17 years old Argentine subjects (157 boy and 157 girls), and to another sample of 240 Argentine subjects, consisting of 127 boys and 113 girls of 20 years of age. Means, standard deviations and percentile ranks for both samples were obtained. To compare groups of different sex and age test of significance for mean differences of independent samples were applied. Boys obtained scores significantly higher than girls, without taking into consideration the age, in Factors C (lower ego strength-higher ego strength), E (submissiveness-dominance), H (threctia-parmia), Q1 (conservativism of temperament-radicalism) and Q3 (low self-sentiment integration - high strength of self sentiment). Contrarywise, girl showed scores significantly higher than boys of the same age in factors I (harria-premsia), N (artlessness-shrewdness), O (untroubled adequacy-guilt proneness) and Q4 (low ergic tension-high ergic tension).

Background Current evidence on breast cancer among US Hispanic women indicates a significant public health threat, although few studies assess the heterogeneity in breast cancer risk among Hispanics of different origin. Methods The 2000 and 2005 National Health Interview Survey (NHIS) Cancer Control Modules were used to examine the Breast Cancer Risk Assessment Tool (BCRAT) 5-year and lifetime risk of invasive breast cancer among Mexican/Mexican-American, Puerto Rican, Cuban/Cuban-American, Dominican (Republic), Central/South American, Other Hispanic and non-Hispanic white (NHW) women aged 35-84 years. Multiple linear regression models were used to compare the BCRAT 5-year and lifetime breast cancer risk between: i) Hispanics and NHWs and ii) Hispanic subgroups. Results Hispanics had significantly lower mean BCRAT 5-year and lifetime breast cancer risk compared to NHWs (p<0.001). Among Hispanic subgroups, Cuban/Cuban-Americans had a higher BCRAT 5-year risk (p<0.05), while Dominicans had a higher lifetime risk (p<0.001), compared to Mexican/Mexican-American women. Approximately, 2.6% of Hispanic women were at high-risk for breast cancer (BCRAT 5-year risk ≥1.67%), ranging from 1.0% of Central/South Americans to 3.7% of Puerto Ricans; few Hispanics (0.2%) had a lifetime risk ≥20.0%. Conclusions Our findings indicate that Hispanics had significantly lower risk of breast cancer, compared to NHWs, though BCRAT risk significantly differed between specific Hispanic subgroups. We provide estimates of the number of US Hispanic women, from six subgroups, who would be eligible for prophylactic breast cancer chemoprevention. Future studies should further investigate the heterogeneity in breast cancer risk and risk factors between Hispanic women of different origins. PMID:23224859

BACKGROUND: In a cross-sectional study examining late effects of pediatric sarcoma therapy, long-term survivors were evaluated on their activities of daily living (ADL) performance. PROCEDURE: Thirty-two persons with Ewing sarcoma family of tumors, rhabdomyosarcoma, and non-rhabdomysarcoma-soft tissue sarcoma enrolled an average of 17 years after treatment. Participants were evaluated using the Assessment of Motor and Process Skills (AMPS) [1], a standardized observational evaluation of ADL task performance. Means and 95% confidence intervals for ADL motor and ADL process ability measures were calculated for four groups: 1) sarcoma survivors, 2) “well” adults matched for age and gender, 3) “well” adults matched for gender that were 10 years older; and 4) “well” adults matched for gender that were 20 years older. RESULTS: ADL motor ability was significantly lower for sarcoma survivors than for the age and gender matched comparison group (p<0.05). There was no significant difference between ADL motor ability of sarcoma survivors and the comparison group 10 years older, but sarcoma survivors had significantly better ADL motor ability (p<0.05) than the oldest comparison group (20 years older). Sarcoma survivors had significantly worse ADL process ability than the age matched group (p<0.05). There was no difference in ADL process ability between the sarcoma survivors and comparison groups that were 10 and 20 years older. CONCLUSIONS: This first report of a clinical evaluation of ADL limitation in pediatric sarcoma survivors treated with intensive multimodal cancer therapy suggests that influences on performance of daily life activities are more common than previously reported.

To compare the treatment outcomes of DSM-IV-TR schizophrenia patients in either a Community Treatment Program or an Individual Treatment Program (CTP vs. ITP). The assessment was made after the first hospitalization, and then after three and twelve years. Participants were randomly assigned to CTP (experimental) and ITP (traditional) group, with 40 people in each group. 67 people (84%) participated in all three assessments. The socio-demographic and clinical indicators were the same for both groups. In the first three years only the CTP group participated in day-care treatment, patient and family psychoeducation and community treatment. Later, both groups received this treatment. The following tools were used: Anamnestic and Catamnestic Questionnaire, the GAF scale, the BPRS LA and Lehman's Quality of Life Interview. It was only after twelve years that there was a significant beneficial improvement in the mean GAF score in the CTP group (p = 0.036), which was comparable with the results obtained by Watt and Shepherd for the course of the illness in favorable remission cases (p = 0.038). The difference in the number of relapses was also significantly in favor of the CTP group only after 12 years (p = 0.045), as was the difference in the number of rehospitalizations (p = 0.013). The general severity of symptoms was found to be significantly lower for the CPT group after 3 (p = 0.008) and 12 years (p = 0.030), whereas it was significantly lower in the case of positive syndrome only after 3 years (p = 0.044). 1. A greater number of favorable differences were identified for the CTP group at the twelve-year point than at the conclusion of the experiment. 2. The three-year delay in introducing psycho-social treatment was associated with a poorer long-term outcome for the clinical course of schizophrenia.

The aim of this study is to estimate the prevalence of spine and feet deformities among children who are regularly involved in basketball trainings, as well as finding differences in the prevalence of those deformities between children of different gender and age. The study included a total of 64 children, of which 43 were boys and 21 were girls, ages 10-12. All subjects have been regularly participating in basketball trainings for at least one year. Postural disorder is defined as an irregularity in posture of the spine and feet, and it is assessed by visual methods from the front, side and rear side of the body. The prevalence of spinal deformities in our group was 53.13%. The boys had a significantly higher prevalence than girls, 65.1% compared to 28.57% (p=0.006). There was no significant difference in prevalence of spine deformities between children of different ages. The prevalence of feet deformities was 64.06%. There was a statistically significant difference between the sexes, where boys had a significantly greater prevalence of the feet deformities than girls, 83.7% compared to 23.81% (p=0.001). Flat feet were the most common in 10 year old children (85.71%). In conclusion, it can be said that despite regular participation in basketball training, subjects in this study have high prevalence of deformities; especially boys who stand out with the high prevalence of flat feet.

Objective To evaluate the effect of long term utilization of chemical disinfectants on the color of porcelain shade guides. Methodology three chemical disinfectants were used in this study: Minuten spray, Lysol ICQuaternary Disinfectant Cleaner (QDC), and Lysol IC Ready to Use Disinfectant Cleaner (RDC). Simulation of disinfecting cycles for one year, two years, and three years were done on Vita 3D master shade guide. Color differences were determined by visual inspection and analyzing ΔE. Results ΔE values were significantly below the perceptible (ΔE=1) and the clinically acceptable (ΔE=3.7) thresholds. Conclusions Simulated utilization of Minuten Spray, Lysol IC (QDC), and Lysol (RDC) disinfectants for up to three years didn’t cause a clinically significant difference in the color of VITA Toothguide 3D-Master Shade Guide.

The appearance of lumbal syndrome was analysed in two groups of workers in the "Zagrebacka pivovara" brewery. In a group of 23 workers whose mean age was 34 years and mean length of service 12 years, nine (39.1%) suffered from lumbal syndrome. In another group of 33 workers, with the mean age of 31 years and the mean length of service of nine years there were 24 (72.7%) suffering from the syndrome. According to Student's t-test the differences in age and length of service between the two groups were not significant (P > 0.05), but the difference in the number of ill was significant (P < 0.05). Analysis of the workplace showed that a heavy burden of the lumbal spine was involved, especially with the workers from the second group, and that ergonomic solutions were necessary.

The aim of this study was to examine the differences in psychosocial and motivational variables between persistent and dropout youth athletes and between groups with different years in training. Team and individual youth athletes completed questionnaires measuring autonomy support from parents and coaches, peer motivational climate, basic psychological needs satisfaction, and sport motivation. The results showed that athletes who dropped out perceived significantly less competence, relatedness, and autonomy need satisfaction, and they perceived less autonomy support from parents and were less intrinsically motivated than persistent athletes. Youth athletes with up to one year in training reported significantly lower effort and intra-team conflict with peers, relatedness need satisfaction, and external motivation than athletes with 1 to 3 years and >3 years in training. Findings extend knowledge of the psychosocial determinants of sport continuation behaviour among young athletes.

The growth and health of cultured blue mussels (Mytilus edulis) are affected by environmental conditions. Typically, culture sites are situated in sheltered areas near shore (i.e., < 1 km distance from land, < 20 m depth); however, land runoff, user conflicts and environmental impact in coastal areas are concerns and interest in developing deep water (> 20 m depth) mussel culture has been growing. This study evaluated the effect of culture depth on blue mussels in a cold water coastal environment (Newfoundland, Canada). Culture depth was examined over two years from September 2012 to September 2014; mussels from three shallow water (5 m) and three deep water (15 m) sites were compared for growth and biochemical composition; culture depths were compared for temperature and chlorophyll a. Differences between the two years examined were noted, possibly due to harsh winter conditions in the second year of the experiment. In both years shallow and deep water mussels presented similar condition; in year 2 deep water mussels had a significantly better biochemical profile. Lipid and glycogen analyses showed seasonal variations, but no significant differences between shallow and deep water were noted. Fatty acid profiles showed a significantly higher content of omega-3 s (20:5ω3; EPA) and lower content of bacterial fatty acids in deep water sites in year 2. Everything considered, deep water appeared to provide a more favorable environment for mussel growth than shallow water under harsher weather conditions.
Teasing apart the relations between age, birth cohort, and vocational interests.

Empirical evidence supports that aging is related to differences in work attitudes and motivation (Inceoglu, Segers, & Bartram, 2012; Kooij, de Lange, Jansen, Kanfer, & Kikkers, 2011; Ng & Feldman, 2008, 2010), but little research has explored the relations between age and vocational interests. Furthermore, recent studies of age and work attitudes suggest that generational experiences (i.e., birth year) may account for age differences in the workplace (Inceoglu et al., 2012; Ng & Feldman, 2008, 2010), which in turn suggests that researchers need to incorporate both age and birth cohort effects in their designs. Thus, this study was designed to explore the relations of age at the time of testing and birth year to vocational interests using a sample of adults (N = 1,792) collected over a period of 3 decades. As expected, age was not a significant predictor of most interests, but birth year also was not found to predict most interests, with the significant prediction of Realistic interests by both age and birth year being the exception. Gender, however, significantly predicted most areas of interests. Neither age nor gender moderated any relationships between birth year and interests. Results suggest that birth year and age were minimally related to interests as all effect sizes were small. Discussion of the results illustrates the need for further research on this issue and also offers considerations for attracting and retaining different generations of workers in light of the findings.

To determine the addition of value of neoadjuvant, concurrent and adjuvant chemotherapy to radiation in the treatment of nasopharyngeal carcinoma with regard to the overall survival (OS) and disease free survival (DFS) within a six year period in Tehran cancer institute. Files of all patients with nasopharyngeal carcinoma treated by radiotherapy with or without concurrent chemotherapy in a curative setting in Tehran cancer institute during the period of 1999-2005 were retrospectively reviewed.. A total of 103 patients with nasopharyngeal carcinoma had been treated during the study period with radiotherapy or chemoradiotherapy in our institute. There were 29 (28.2%) females and 74 (71.8%) males. The median age at the time of radiotherapy was 47 years old (range 9-75 years). The patients were followed 2 to 76 months with a median follow-up of 14 months. Time of first recurrence after treatment was 3-44 months with a median of 10 months.. Survival in 2 groups of patients treated with radiotherapy alone or chemoradiation did not have a significant difference (P>0.1). Two-year survival in patients treated with or without adjuvant chemotherapy and had local recurrence after treatment did not have significant difference (P>0.1). Two-year survival in patients with or without local recurrence after treatment did not have significant difference (P>0.1). A beneficial affect or a survival benefit of adjuvant/neoadjuvant chemotherapy and concurrent chemoradiation was not observed in Iranian patients.

In order to reveal the dynamics of canopy vertical structure and its effects on understory regeneration, we built 24 permanent plots (20 m×20 m) on the upslope, midslopeand downslope, respectively, in a typical evergreen broadleaved forest in Damingshan, Guangxi, China. We measured the crown area of each tree with diameter at breast height (DBH)≥1.0 cm, and surveyed the understory regeneration in growing season from 2009 to 2011. The results showed that the total canopy cover significantly increased from 54.0% in 2009 to 67.4% in 2011 after the frozen disaster in 2008. A significant difference existed in the cover and increment of different canopy layers. The canopy cover in the upper layers was markedly higher than that in the middle and lower layers. The increment of canopy coverage in the middle and lower layers was significantly higher than that in the upper layer. There were 55 regenerated woody plant species, and the dominant families and species of regenerated plants were in accord with those in the evergreen broadleaved forest. Biodiversity index of regenerated plants in the same slope position was significantly different among different years, and no significant difference was observed among different slope positions in the same year. The correlation between the coverage at different canopy layers and the species richness and abundance of regenerated plants was not significant. Total canopy cover and canopy coverage at the middle and lower layers were significantly negatively correlated with the Shannon index, Simpson index, and Pielou evenness index of the understory regenerated plants. It indicated that canopy coverage had a significant influence on the regeneration of understory, and the middle and lower layers had a stronger influence on the biodiversity of regenerated plants.

An extensive analysis of the relationships between strongylid egg shedding in domestic horses and the strongylid community structure in regard to the age of the horses, their breeds and different strategies of horse management, particularly with anthelmintic treatment programs was performed. Domestic horses (n=197) of different ages (5 months to 22 years) and of various breeds from 15 farms with different types of deworming programs were included in this study. Strongylids (totally, 82,767 specimens) were collected in vivo after deworming of the horses with the macrocyclic lactone anthelmintic ("Univerm", 0.2% aversectin C), and identified to the species level. Models of multiple regressions with dummy variables were used to estimate the effects of age, breed, type of farm and deworming programs on number of eggs shed per gram of feces (EPG value) and the strongylid community. Totally, 33 strongylid species were collected (8 species of Strongylinae and 25 - of Cyathostominae); a significant correlation (r=0.67; p<0.001) between the prevalence and proportion of species in the strongylid community was observed. The highest number of species (32) was found in young horses (1.5-4 years old); the lowest (17) - in old horses (>16years). Foals (<1year old) had significantly higher EPG value than older horses. The linear regression models of the strongyle egg counts (EPG) with three predictors: horse age (AGE), number of strongylids (SN), and type of farm (FARM) revealed significant effects of SN and FARM, but an effect of AGE was near the limit of significance. Horses from farms with rare or no anthelmintic treatments (type A) shed significantly more strongyle eggs than horses from farms with regular treatments; frequency of dewormings - 1-2 (type B) or 3-4 and more times per year (type C) did not have a significant impact on the EPG value. Thoroughbreds, Ukrainian Saddlers and Russian Racers had much higher EPG values comparing to non-breed horses. Analysis of the relation of age of the horses and structure of the strongylid communities revealed that foals (<1year old) and old horses (>16years old) were significantly less infected by large strongyles as compared to other horses. Species from the genus Triodontophorus and Strongylus vulgaris infected foals and young horses; whereas S. edentatus and S. equinus were registered in horses >1.5years old. Differences in proportions of separate strongylid species in the community related to age were insignificant (p>0.05). Frequency of anthelmintic treatments was found to affect horses infections with strongylids and strongylid community structure much more than intrinsic factors such as age and breed.

Introduction It is generally accepted that estrogens play a protective role in cognitive function. Therefore, it can be expected that subtotal estrogen deprivation following aromatase inhibition will alter cognitive performance. Methods In a cross-sectional study we investigated 80 postmenopausal women with breast cancer. Memory and spatial cognition were compared across 4 treatment groups: tamoxifen only (TAM, n = 22), aromatase inhibitor only (AI, n = 22), TAM followed by AI (‘SWITCH group’, n = 15), and patients with local therapy (LT) only (surgery and radiation, n = 21). Duration of the 2 endocrine monotherapy arms prior to the assessment ranged from 1 to 3 years. The ‘SWITCH group’ received 2-3 years TAM followed by at least 1 year and at most 3 years of AI. Memory and spatial cognition were investigated as planned comparisons. Investigations of processing speed, attention, executive function, visuoconstruction and self-perception of memory were exploratory. Results With regard to general memory, AI patients performed significantly worse than the LT group (p = 0.013). Significant differences in verbal memory did not remain significant after p-value correction for multiple testing. We found no significant differences concerning spatial cognition between the groups. Conclusion AI treatment alone significantly impairs general memory compared to the LT group. PMID:27721710
Ideal resuscitation pressure for uncontrolled hemorrhagic shock in different ages and sexes of rats
2013-01-01
Introduction Our previous studies demonstrated that 50-60 mmHg mean arterial blood pressure was the ideal target hypotension for uncontrolled hemorrhagic shock during the active hemorrhage in sexually mature rats. The ideal target resuscitation pressure for immature and older rats has not been determined. Methods To elucidate this issue, using uncontrolled hemorrhagic-shock rats of different ages and sexes (6 weeks, 14 weeks and 1.5 years representing pre-adult, adult and older rats, respectively), the resuscitation effects of different target pressures (40, 50, 60, 70 and 80 mmHg) on uncontrolled hemorrhagic shock during active hemorrhage and the age and sex differences were observed. Results Different target resuscitation pressures had different resuscitation outcomes for the same age and sex of rats. The optimal target resuscitation pressures for 6-week-old, 14-week-old and 1.5-year-old rats were 40 to 50 mmHg, 50 to 60 mmHg and 70 mmHg respectively. Ideal target resuscitation pressures were significantly superior to other resuscitation pressures in improving the hemodynamics, blood perfusion, organ function and animal survival of uncontrolled hemorrhagic-shock rats (P < 0.01). For same target resuscitation pressures, the beneficial effect on hemorrhagic shock had a significant age difference (P < 0.01) but no sex difference (P > 0.05). Different resuscitation pressures had no effect on coagulation function. Conclusion Hemorrhagic-shock rats at different ages have different target resuscitation pressures during active hemorrhage. The ideal target resuscitation hypotension for 6-week-old, 14-week-old and 1.5-year-old rats was 40 to 50 mmHg, 50 to 60 mmHg and 70 mmHg, respectively. Their resuscitation effects have significant age difference but had no sex difference. PMID:24020401

Using longitudinal data from early adolescence through young adulthood, this study examined the association between different types of postsecondary education (PSE), age of enrollment in PSE, and the trajectory of alcohol use for Canadian young adults (N = 521). Trajectories of alcohol use were compared across young adults at 2-year colleges, 4-year universities, transfer programs (started at a 2-year college and transferred to a 4-year university), and terminal high school graduates. While initial findings revealed significant differences in the drinking trajectories of 2-year college students and 4-year university students, all differences were accounted for by variability in the age of enrollment. Overall, there were few differences in heavy drinking across types of institutions, but younger students increased their alcohol use more than older students following enrollment. However, young adults who do not attend PSE may be at greatest risk for heavy drinking over time. PMID:27308184

The influence of age on the patterns and outcomes of external beam radiotherapy for clinically localized prostate cancer patients was examined. The Japanese Patterns of Care Study surveys were used to compare the processes and outcomes of radical external beam radiotherapy in 140 elderly patients (>75 years old) and 304 younger patients (<75 years old). Although the Karnofsky performance status was significantly different between elderly and younger patients, there were no significant differences in disease characteristics such as pretreatment PSA level, differentiation, Gleason combined score and clinical T stage. There were also no significant differences in the treatment characteristics such as CT-based treatment planning, conformal therapy, total radiation doses (both a median of 66.0 Gy) and hormonal therapy usage. Moreover, no significant differences in overall survival, biochemical relapse-free survival and late toxicity rates were observed between elderly and younger patients. Age did not influence the disease characteristics, patterns of external beam radiotherapy, survival and late toxicities for clinically localized prostate cancer patients. Therefore, radiotherapy could represent an important treatment modality for elderly patients as well as for younger ones.
Changes in the body posture of women occurring with age
2013-01-01
Background A current topic in the field of geriatrics still needing a great deal of study is the changes in body posture occurring with age. Symptoms of these changes can be observed starting between the ages of 40–50 years with a slow progression that increases after 60 years of age. The aims of this study were to evaluate parameters characterizing the posture of women over the age of 60 years compared with a control group and to determine the dynamics of body posture changes in the following decades. Methods The study included 260 randomly selected women. The study group consisted of 130 women between the ages of 60–90 years (Older Women). The control group (Younger Women) consisted of 130 women between the ages of 20–25 years (posture stabilization period). The photogrammetric method was used to evaluate body posture using the phenomenon of the projection chamber. The study was conducted according to generally accepted principles. Results In the analysis of parameters characterizing individual slope curves, results were varied among different age groups. The lumbar spine slope did not show significant differences between different age groups (p = 0.6952), while statistically significant differences (p = 0.0000) were found in the thoracic-lumbar spine slope (p = 0.0033) and upper thoracic spine slope. Body angle was shown to increase with age (p = 0.0000). Thoracic kyphosis depth significantly deepened with age (p = 0.0002), however, the thoracic kyphosis angle decreased with age (p = 0.0000). An increase in asymmetries was noticed, provided by a significantly higher angle of the shoulder line (p = 0.0199) and the difference in height of the lower shoulder blade angle (p = 0.0007) measurements in the group of older women. Conclusions Changes in the parameters describing body posture throughout consecutive decades were observed. Therapy for women over the age of 60 years should involve strengthening of the erector spinae muscles and controlling body posture with the aim of reducing trunk inclination and deepening of thoracic kyphosis. Moreover, exercises shaping lumbar lordosis should be performed to prevent its flattening. PMID:24119004

In this cross-sectional study, we examined age-related differences in anxiety sensitivity (AS), experiential avoidance (EA), and mindfulness among younger adult students (N=426; M age=20.1 years) and community-dwelling older adults (N=85; M age=71.8 years). Participants anonymously completed the Anxiety Sensitivity Index-3, Acceptance and Action Questionnaire-II, Mindful Attention Awareness Scale, Kentucky Inventory of Mindfulness Skills, Beck Anxiety Inventory, Geriatric Anxiety Scale, and State-Trait Anxiety Inventory. Independent t tests indicated that younger adults reported significantly higher levels of AS and EA, whereas older adults reported significantly higher levels of trait mindfulness. Correlational analyses demonstrated that AS and EA were significantly associated with each other and with anxiety-related symptoms. However, trait mindfulness was significantly inversely related to AS, EA, and to trait and state anxiety. To date, these three factors have yet to be examined simultaneously within the context of age differences, and the present study illuminates these differences as well as their relationships. AS, EA, and low mindfulness appear to be significant correlates for anxiety-related symptoms in younger and older adults. © The Author(s) 2015.

To investigate the potential effects of differences between growth locations on the cell wall composition and saccharification efficiency of the bioenergy crop miscanthus, a diverse set of 15 accessions were evaluated in six locations across Europe for the first 3 years following establishment. High-throughput quantification of cellulose, hemicellulose and lignin contents, as well as cellulose and hemicellulose conversion rates was achieved by combining near-infrared reflectance spectroscopy (NIRS) and biochemical analysis. Prediction models were developed and found to predict biomass quality characteristics with high accuracy. Location significantly affected biomass quality characteristics in all three cultivation years, but location-based differences decreased toward the third year as the plants reached maturity and the effect of location-dependent differences in the rate of establishment reduced. In all locations extensive variation in accession performance was observed for quality traits. The performance of the different accessions in the second and third cultivation year was strongly correlated, while accession performance in the first cultivation year did not correlate well with performance in later years. Significant genotype-by-environment (G × E) interactions were observed for most traits, revealing differences between accessions in environmental sensitivity. Stability analysis of accession performance for calculated ethanol yields suggested that selection for good and stable performance is a viable approach. Environmental influence on biomass quality is substantial and should be taken into account in order to match genotype, location and end-use of miscanthus as a lignocellulose feedstock. PMID:28111583

We used surface-based morphometry to test for differences in cortical shape between children with simplex autism (n = 34, mean age 11.4 years) and typical children (n = 32, mean age 11.3 years). This entailed testing for group differences in sulcal depth and in 3D coordinates after registering cortical midthickness surfaces to an atlas target using 2 independent registration methods. We identified bilateral differences in sulcal depth in restricted portions of the anterior-insula and frontal-operculum (aI/fO) and in the temporoparietal junction (TPJ). The aI/fO depth differences are associated with and likely to be caused by a shape difference in the inferior frontal gyrus in children with simplex autism. Comparisons of average midthickness surfaces of children with simplex autism and those of typical children suggest that the significant sulcal depth differences represent local peaks in a larger pattern of regional differences that are below statistical significance when using coordinate-based analysis methods. Cortical regions that are statistically significant before correction for multiple measures are peaks of more extended, albeit subtle regional differences that may guide hypothesis generation for studies using other imaging modalities.

The aims of this prospective randomised clinical study were to clinically evaluate a radiopaque, highly filled, hybrid, light-activated resin-based composite for posterior teeth (Occlusin, ICI Dental, Macclesfield, UK and GC Dental, Tokyo, Japan) and compare the performance of restorations placed using rubber dam or cotton roll isolation. One clinician placed 100 (42 Class I and 58 Class II) restorations of the material under investigation. The isolation mode for each restoration was determined randomly: 52 preparations were protected from contamination with cotton rolls and aspiration, and 48 preparations were isolated under rubber dam. At baseline and periodically thereafter (0.5, 1, 2, 3, 4, 5, 6, and 10 years), each composite was evaluated by two practitioners using a modified (USPHS) rating system. After 10 years, 37 restorations were reviewed. The results showed satisfactory clinical performance with and without rubber dam after 10 years. A concern was the number of failures at 10 years due to unsatisfactory proximal contact. The evaluations for the surviving restorations were acceptable but with a large reduction in the percentage with ideal occlusal and proximal anatomy. The 10-year comparison of isolation modes showed no statistically significant differences (Kruskal-Wallis test) for each of the evaluation criteria. Furthermore, survival analysis showed no significant difference between the groups (Mantel-Haenszel method). It was concluded that the 10-year clinical behaviour of the restorations of a posterior composite placed under well-controlled, effective isolation with cotton rolls and aspiration, was not significantly different from the behaviour of restorations placed using rubber dam isolation.

To clarify the changes of esophageal motility along with age, we performed esophageal manometry on 47 healthy volunteers, and compared the values of four groups under 49 years old (n = 11), 50 to 59 (n = 15), 60 to 69 (n = 11), and over 70 years old (n = 10). Resting lower esophageal sphincter (LES) pressure in the group over 70 years old showed the tendency of decrease, but not statistically significant. Nadir LES pressure on swallow-induced relaxation was not statistically different among 4 groups. On esophageal body testing, percentage of non-conduction sequence in the group 60 to 69 and over 70 years old was statistically higher compared with that of the group under 49 years old (p < 0.05) but spared in some elderly subjects. Percentage of simultaneous contractions was not statistically different among 4 groups. Peristaltic contraction amplitude in the group over 70 years old was significantly lower than that of the group under 49 years old both at the level of 5 cm above (p < 0.01) and 10 cm above LES (p < 0.05). We speculate that the influence of aging on esophageal motility is the reduced transmission sequence of peristalsis and contractility of esophageal body. This alteration along with age may differ from the pathological condition of scleroderma or diffuse esophageal spasm.

The International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form is a patient-reported outcome with adult (1998) and pediatric (2011) versions validated at different ages. Prior longitudinal studies of patients aged 13 to 17 years who tore their anterior cruciate ligament (ACL) have used the only available adult IKDC, whereas currently the pediatric IKDC is the accepted form of choice. This study compared the adult and pediatric IKDC forms and tested whether the differences were clinically significant. The hypothesis was that the pediatric and adult IKDC questionnaires would show no clinically significant differences in score when completed by patients aged 13 to 17 years. Cohort study (diagnosis); Level of evidence, 2. A total of 100 participants aged 13 to 17 years with knee injuries were split into 2 groups by use of simple randomization. One group answered the adult IKDC form first and then the pediatric form. The second group answered the pediatric IKDC form first and then the adult form. A 10-minute break was given between form administrations to prevent rote repetition of answers. Study design was based on established methods to compare 2 forms of patient-reported outcomes. A 5-point threshold for clinical significance was set below previously published minimum clinically important differences for the adult IKDC. Paired t tests were used to test both differences and equivalence between scores. By ordinary least-squares models, scores were modeled to predict adult scores given certain pediatric scores and vice versa. Comparison between adult and pediatric IKDC scores showed a statistically significant difference of 1.5 points; however, the 95% CI (0.3-2.6) fell below the threshold of 5 points set for clinical significance. Further equivalence testing showed the 95% CI (0.5-2.4) between adult and pediatric scores being within the defined 5-point equivalence region. The scores were highly correlated, with a linear relationship (R(2) = 92%). There was no clinically significant difference between the pediatric and adult IKDC form scores in adolescents aged 13 to 17 years. This result allows use of whichever form is most practical for long-term tracking of patients. A simple linear equation can convert one form into the other. If the adult questionnaire is used at this age, it can be consistently used during follow-up. © 2015 The Author(s).

Genital development is affected by pubertal process to a great extent, and puberty is a complex phenomenon that is influenced by multiple factors resulting in individual differences. We studied penile length and its relationship to pubertal stage in boys 13 to 15 years old. Healthy boys who were candidates for military high school were evaluated between June and July 2011. Age, residence and body mass index were recorded. Stretched penile length was measured. Pubic hair was assessed according to Tanner and Marshall staging. Genital puberty stage was defined by measurement of testicular volume with Prader orchidometer. Relationship of penile length to age, residence, pubertal stages and body mass index was evaluated statistically. A total of 1,539 boys were included in the study. Mean ages and number of patients according to genital stage were as follows. Mean age was 14 years for genital stage 1 (5 patients), 13.9 years (range 13 to 15) for stage 2 (194), 14.07 years (13 to 15) for stage 3 (965) and 14.11 years (13 to 15) for stage 4 (375). Linear regression analysis revealed a significant effect of body mass index, genital stage and pubic hair stage on penile length (p <0.001) but no significant effect of age or residence. Mean penile length was significantly different among different age groups and among pubertal stages. However, mean penile lengths of different age groups within the same pubertal stage were similar. Penile length during puberty should be evaluated individually according to the current pubertal stage. Our study offers a reliable reference table of penile length for pubertal age group.

Introduction: Local ablative therapy and trans arterial chemoembolization (TACE) are applied to ablate non resectable hepatocellular carcinoma (HCC). Combination of both techniques has proven to be more effective. We aimed to study combined ablation techniques and assess survival benefit comparing TACE with radiofrequency (RFA) versus TACE with microwave (MWA) techniques. Methods: We retrospectively studied 22 patients who were ablated using TACE-RFA and 45 with TACE-MWA. All were classified as Child A-B and lesions did not exceed 5 cm in diameter. TACE was followed within two weeks by either RFA or MWA. We recorded total and partial ablation rates and complication rates. Survival analysis was then performed. Results: TACE-MWA showed a higher tendency to provide complete response rates than TACE-RFA (P 0.06). This was particularly evident with lesions sized 3-5 cm (P 0.01). Rates of complications showed no significant difference between the groups. Overall median survival was 27 months. The overall actuarial probability of survival was 80.1% at 1 year, 55% at 2 years, and 36.3% at 3 years. The recurrence free survival at 1 year, 2years and 3 years for the TACE-RFA group was 70%, 42% and 14% respectively and for TACE-MWA group 81.2%, 65.1% and 65.1% without any significant difference (P 0.1). In relation to the size of focal lesions, no statistically significant difference in the survival rates was detected between the groups. Conclusion: TACE-MWA led to better response rates than TACE-RFA with tumors 3-5 cm, with no difference in survival rates. Creative Commons Attribution License

The present commercial market supports many nonsteroidal endocardial pacing leads of differing construction. In order to compare the performance of these configurations, we studied the long-term pacing properties of three representative lead types by randomized clinical trial in 99 patients undergoing a first elective VVI implant. Thirty-one patients received sintered platinum leads, 36 activated pyrolytic carbon leads, and 32 vitreous carbon leads. All received generators capable of noninvasive threshold testing. Acute sensing parameters were R wave amplitude and ST segment elevation measured from the endocardial electrogram. Noninvasive voltage thresholds were measured at implantation, 2 days, 1, 3, and 6 months, and yearly thereafter for 5 years. There were no significant differences between leads in pacing or sensing capabilities at implantation. All three demonstrated similar increases in thresholds, peaking at 1 month, then falling to a plateau by 6 months and did not vary significantly thereafter. There were no significant differences in thresholds between leads during 5 years of follow-up. The lowest mean threshold at 5 years was 0.93 V at 0.5 ms. This study suggests that: (1) although these lead types all perform well, none offers any particular clinical advantage over another; (2) the degree of early threshold peaking precludes immediate postimplant output reduction, but later thresholds are sufficiently low to enable reductions in pacing output; (3) safe low energy pacing requires greater attention to the lead-generator combinations; (4) data obtained at subsequent annual follow-up provided no additional useful clinical information to that obtained at 1 year; and (5) in the absence of other differences, cost can be the deciding factor in lead selection.
Behavioral Problems and Childhood Epilepsy: Parent vs Child Perspectives.

To test whether the reported association between pediatric epilepsy and behavioral problems may be distorted by the use of parental proxy report instruments. Children in the Connecticut Study of Epilepsy were assessed 8-9 years after their epilepsy diagnosis (time-1) with the parent-proxy Child Behavior Check List (CBCL) (ages 6-18 years) or the Young Adult Self-Report (≥18 years of age). For children <18 years of age, parents also completed the Child Health Questionnaire, which contains scales for impact of child's illness on the parents. The same study subjects completed the Adult Self-Report 6-8 years later (time-2). Sibling controls were also tested. Case-control differences were examined for evidence suggesting more behavioral problems in cases with epilepsy than in controls based on proxy- vs self-report measures. At time-1, parent-proxy CBCL scores were significantly higher (worse) for cases than controls (n = 140 matched pairs). After adjustment for Child Health Questionnaire scales reflecting parent emotional and time impact, only 1 case-control difference on the CBCL remained significant. Self-reported Young Adult Self-Report scores did not differ between cases and controls (n = 42 pairs). At time-2, there were no significant self-reported case-control differences on the Adult Self-Report (n = 105 pairs). Parent-proxy behavior measures appear to be influenced by the emotional impact of epilepsy on parents. This may contribute to apparent associations between behavioral problems and childhood epilepsy. Self-report measures in older adolescents (>18 years of age) and young adults do not confirm parental perceptions. Evidence suggesting more behavioral problems in children with epilepsy should be interpreted in light of the source of information. Copyright © 2016 Elsevier Inc. All rights reserved.

Purpose The aim of this study was to report normative values and ranges of interpupillary distance (IPD) in different age groups of a Turkish population. Methods A total of 756 healthy subjects were included in this prospective study. After a complete ophthalmic evaluation, subjects were divided into four age groups to assess differences between age groups in relation to IPD. The age groups were 20–30, 31–50, 51–70, and 71–89 years. Far IPD measurements were performed using an autorefractometer (Topcon RM-8800). Results The mean age was 48.42±20.55 years, ranging from 19 to 89 years. The mean IPD was calculated as 62.5±4.1 mm (range 49–76). The mean IPD value was observed to be significantly higher among males compared to females (P<0.001). The difference among groups in terms of mean IPD was statistically significant (P<0.001). IPD increased by 4.19 mm in males and 3.11 mm in females from the young adults (20–30 years) to older adults (51–70 years), and then a decrease (2.6 and 0.19 mm for males and females, respectively) occurred between 70 and 89 years of age. Conclusion The current study offers the population-specific normative data on far IPD in different age groups. Our study showed that sex and age had a significant effect on IPD. Knowledge of normal values in this population subgroup may be useful in studying orbito-cranial growth patterns, syndrome diagnosis, surgical management of cranio-facial deformities and trauma, and manufactures of optical frames and lenses.

McGuigan, Michael R; Ghiagiarelli, Jamie; Tod, David
2005-07-01
We studied the effect of psyching-up on one-repetition maximum (1-RM) performance and salivary cortisol responses during the squat exercise. Ten men (age 21.6+/-1.4 years; mean+/-s) and ten women (age 22.4+/-2.8 years) with weight training experience of 4.5+/-2.0 years participated in this study. One-repetition maximum squats were performed on a Smith machine during each of two different intervention conditions that were counterbalanced and consisted of a free choice psych-up and a cognitive distraction. Saliva samples were obtained at the beginning of each test session and immediately after the final 1-RM attempt. No significant difference in 1-RM was identified between psyching-up (104+/-50 kg) and cognitive distraction (106+/-52 kg). Performing a 1-RM in the squat exercise significantly increased salivary cortisol concentrations during both conditions (P<0.05). There was no significant difference in salivary cortisol responses between conditions. These results suggest that psyching-up does not increase 1-RM performance during the squat exercise in strength-trained individuals.

Using the incidence data from 1989 to 2008 of liver cancer from population in cancer registration areas in China, the differences and changes of gender, urban and rural areas for liver cancer incidence in different years were studied, and the mean age of incidence was analyzed. The incidence data of liver cancer from National Cancer Registration database were sorted and checked. A total of 181 097 new liver cancer cases were collected, covering 711 843 051 person years from 1989 to 2008.Using Poisson regression model, Stratified by gender and areas, changes of incidence gender ratio, ratio of urban and rural, and mean age were analyzed. After adjusting the age, the liver cancer incidence in male was about 3 times higher than that in females (ranging from 2.64-3.54), and the ratio change between male and female for the 20 years did not have statistically significant (P = 0.150). The incidence ratio between urban and rural areas has increased from 0.51 in 1989 to 0.61 in 2008 (P < 0.01). The mean ages of diagnosis for male and female increased from 57.14 years to 60.34 years, 61.69 years to 66.47 years, respectively from 1989 to 2008. The mean age of liver cancer diagnosis has increased in the 20 years (P < 0.01). The liver cancer incidence between male and female did not change significantly among 20 years. The difference of liver cancer incidence between urban and rural areas has reduced, and the mean age of diagnosis was deferred.

Observed precipitation variability measures are compared to measures obtained using the World Climate Research Programme (WCRP) Coupled Model Intercomparison Project (CMIP3) General Circulation Models (GCM) data from 36 model projections downscaled by Brekke at al. (2007) and 30 model projections downscaled by Jon Eischeid. Three groups of variability measures are considered in this historical period (1951-1999) comparison: a) basic variability measures, such as standard deviation, interdecadal standard deviation; b) exceedance probability values, i.e., 10% (extreme wet years) and 90% (extreme dry years) exceedance probability values of series of n-year running mean annual amounts, where n=1,12; 10% exceedance probability values of annual maximum monthly precipitation (extreme wet months); and c) runs variability measures, e.g., frequency of negative and positive runs of annual precipitation amounts, total number of the negative and positive runs. Two gridded precipitation data sets produced from observations are used: the Maurer et al. (2002) and the Daly et al. (1994) Precipitation Regression on Independent Slopes Method (PRISM) data sets. The data consist of monthly grid-point precipitation averaged on a United States Geological Survey (USGS) hydrological sub-region scale. The statistical significance of the obtained model minus observed measure differences is assessed using a block bootstrapping approach. The analyses were performed on annual, seasonal and monthly scale. The results indicate that the interdecadal standard deviation is underestimated, in general, on all time scales by the downscaled model data. The differences are statistically significant at a 0.05 significance level for several Lower Colorado Basin sub-regions on annual and seasonal scale, and for several sub-regions located mostly in the Upper Colorado River Basin for the months of March, June, July and November. Although the models simulate drier extreme wet years, wetter extreme dry years and drier extreme wet months for the Upper Colorado basin, the differences are mostly not-significant. Exceptions are the results about the extreme wet years for n=3 for sub-region White-Yampa, for n=6, 7, and 8 for sub-region Upper Colorado-Dolores, and about the extreme dry years for n=11 for sub-region Great Divide-Upper Green. None of the results for the sub-regions in the Lower Colorado Basin were significant. For most of the Upper Colorado sub-regions the models simulate significantly lower frequency of negative and positive 4-6 year runs, while for several sub-regions a significantly higher frequency of 2-year negative runs is evident in the model versus the Maurer data comparisons. The model projections versus the PRISM data comparison reveals similar results for the negative runs, while for the positive runs the results indicate that the models simulate higher frequency of the 2-6 year runs. The results for the Lower Colorado basin sub-regions are similar, in general, to these for the Upper Colorado sub-regions. The differences between the simulated and the observed total number of negative or positive runs were not significant for almost all of the sub-regions within the Colorado River Basin.

Newton-Leo, Linda; King-Isaacs, Debra; Lichti, Janice
1994-01-01
This study was a preliminary investigation into the knowledge of and current attitudes towards the chiropractic profession by medical practitioners with varying years of clinical experience. A questionnaire was designed and mailed to seventy general practitioners in Downsview, Ontario who agreed to participate in the study. Twenty-six were returned for a response rate of 37%. The data were analyzed and responses from doctors with differing years of practice experience were compared using the chi square statistic. When comparing attitudes towards the chiropractic profession between medical practitioners with greater and less than 15 years of clinical experience a statistically significant difference was found (p = 0.0005). However, no significant differences were observed in terms of their interaction with or knowledge of the chiropractic profession. Further, 88% of respondents reported that they had referred a patient to a chiropractor. The limitations of the study and suggestions for improvement are discussed.
Best practices for learning physiology: combining classroom and online methods.
Anderson, Lisa C; Krichbaum, Kathleen E
2017-09-01
Physiology is a requisite course for many professional allied health programs and is a foundational science for learning pathophysiology, health assessment, and pharmacology. Given the demand for online learning in the health sciences, it is important to evaluate the efficacy of online and in-class teaching methods, especially as they are combined to form hybrid courses. The purpose of this study was to compare two hybrid physiology sections in which one section was offered mostly in-class (85% in-class), and the other section was offered mostly online (85% online). The two sections in 2 yr ( year 1 and year 2 ) were compared in terms of knowledge of physiology measured in exam scores and pretest-posttest improvement, and in measures of student satisfaction with teaching. In year 1 , there were some differences on individual exam scores between the two sections, but no significant differences in mean exam scores or in pretest-posttest improvements. However, in terms of student satisfaction, the mostly in-class students in year 1 rated the instructor significantly higher than did the mostly online students. Comparisons between in-class and online students in the year 2 cohort yielded data that showed that mean exam scores were not statistically different, but pre-post changes were significantly greater in the mostly online section; student satisfaction among mostly online students also improved significantly. Education researchers must investigate effective combinations of in-class and online methods for student learning outcomes, while maintaining the flexibility and convenience that online methods provide.

Results of investigations using various lung volumes for hydrostatic weighing determinations (HWD) appear to be inconclusive. Often, these lung volumes are predicted and not clinically determined. For this reason, total lung capacity (TLC), a measured residual volume (RV), and a predicted residual volume (PRV) were used during HWDs to compare the techniques. Twenty-five older men, 56 to 70 years (means +/- 62.1 + 4.2 years) performed HWDs at RV (10 trials) and at TLC (3-5 trials). Values for body density and fat free mass were not significantly different between RV and TLC; both values were, however, significantly different from those derived using PRV. There were statistically significant differences (p less than 0.05) between all 3 per cent body fat values but the 1.1 per cent difference between TLC and RV may not be physiologically important. It was concluded that TLC and RV may be used comparably during HWDs, but a PRV may produce significantly different values. Since HWD at TLC is easily performed and circumvents the difficulties associated with the RV technique, it may be the preferred method for older subjects. PMID:3730758

BACKGROUND Consumption of sugar-sweetened beverages may cause excessive weight gain. We aimed to assess the effect on weight gain of an intervention that included the provision of noncaloric beverages at home for overweight and obese adolescents. METHODS We randomly assigned 224 overweight and obese adolescents who regularly consumed sugar-sweetened beverages to experimental and control groups. The experimental group received a 1-year intervention designed to decrease consumption of sugar-sweetened beverages, with follow-up for an additional year without intervention. We hypothesized that the experimental group would gain weight at a slower rate than the control group. RESULTS Retention rates were 97% at 1 year and 93% at 2 years. Reported consumption of sugar-sweetened beverages was similar at baseline in the experimental and control groups (1.7 servings per day), declined to nearly 0 in the experimental group at 1 year, and remained lower in the experimental group than in the control group at 2 years. The primary outcome, the change in mean body-mass index (BMI, the weight in kilograms divided by the square of the height in meters) at 2 years, did not differ significantly between the two groups (change in experimental group minus change in control group, −0.3; P = 0.46). At 1 year, however, there were significant between-group differences for changes in BMI (−0.57, P = 0.045) and weight (−1.9 kg, P = 0.04). We found evidence of effect modification according to ethnic group at 1 year (P = 0.04) and 2 years (P = 0.01). In a prespecified analysis according to ethnic group, among Hispanic participants (27 in the experimental group and 19 in the control group), there was a significant between-group difference in the change in BMI at 1 year (−1.79, P = 0.007) and 2 years (−2.35, P = 0.01), but not among non-Hispanic participants (P>0.35 at years 1 and 2). The change in body fat as a percentage of total weight did not differ significantly between groups at 2 years (−0.5%, P = 0.40). There were no adverse events related to study participation. CONCLUSIONS Among overweight and obese adolescents, the increase in BMI was smaller in the experimental group than in the control group after a 1-year intervention designed to reduce consumption of sugar-sweetened beverages, but not at the 2-year follow-up (the prespecified primary outcome).

Background Vitamin C has critical features relavant to postoperative pain management and functional improvement; however, no study has yet evaluated the effectiveness of vitamin C on improving the surgical outcomes for spine pathologies. Thus, this study aimed to explore the impact of vitamin C on postoperative outcomes after single-level posterior lumbar interbody fusion (PLIF) for lumbar spinal stenosis in prospectively randomized design. We conducted a 1-year prospective, randomized, placebo-controlled, double-blind study to evaluate the impact of vitamin C on the postoperative outcomes after PLIF surgery. Methods A total of 123 eligible patients were randomly assigned to either group A (62 patients with vitamin C) or group B (61 patients with placebo). Patient follow-up was continued for at least 1 year after surgery. The primary outcome measure was pain intensity in the lower back using a visual analogue scale. The secondary outcome measures were: (1) the clinical outcome assessed using the Oswestry Disability Index (ODI); (2) the fusion rate assessed using dynamic radiographs and computed tomography scans; and (3) complications. Results Pain intensity in the lower back was significantly improved in both groups compared with preoperative pain intensity, but no significant difference was observed between the 2 groups over the follow-up period. The ODI score of group A at the third postoperative month was significantly higher than the score of group B. After the sixth postoperative month, the ODI score of group A was slightly higher than the score of group B; however, this difference was not significant. The fusion rates at 1 year after surgery and the complication rates were not significantly different between the 2 groups. Conclusions Postoperative pain intensity, the primary outcome measure, was not significantly different at 1 year after surgery between the 2 groups. However, vitamin C may be associated with improving functional status after PLIF surgery, especially during the first 3 postoperative months. PMID:28861199

The main goal of the present study is to detect the relationship between youth's leisure time physical activity and a set of sociodemographic (age, gender, family stucture) and socioeconomic variables (SES and parental schooling). Data were collected among Hungarian youth (middle and high school students, N = 1662) aged between 10-20 years using a self-administered questionnaire. Our findings did not indicate gender differences during the years of middle school, whereas gender differences became significant during the years of high school. In multivariate analyses, parental schooling played a decisive role in youth's physical activity, wheres SES self-assessment did not remain significant. These findings provide some useful information on characteristics of the target groups for health education programs.

To compare spectacles plus patching >or=8 hours daily 6 days a week with spectacles plus patching >or=8 hours on alternate days to treat amblyopia in children 4 to 5 years of age. Prospective, randomized clinical trial. Forty children (median age, 4.3 years) with untreated amblyopia and a median best-corrected visual acuity (BCVA) in the amblyopic eye of 0.9 (range, 0.3-1.5) logarithm of the minimum angle of resolution. Refractive correction was provided, and the children were randomized to patching >or=8 hours daily 6 days a week or patching >or=8 hours on alternate days. The BCVA, binocular function, and refractive errors were measured repeatedly during the study. Median change in BCVA of the amblyopic eye after 1 year. The median change in BCVA of the amblyopic eye did not differ significantly between the 2 groups (0.6 log units for daily occlusion; 0.8 log unit for alternate-day occlusion). The final median BCVA in the amblyopic eyes was 0.1 logarithm of the minimum angle of resolution in both groups. Binocular function improved in both groups with no significant differences between the groups at 1 year. The median spherical equivalent refractive error did not change significantly during the study period in the amblyopic eyes in either group; however, a significant increase was found in the fellow eyes in both groups (daily occlusion, P<0.05; alternate-day occlusion, P<0.001). The magnitude of change in the BCVA 1 year after spectacles plus prescribed alternate-day patching was not significantly different than that after spectacles plus prescribed daily patching to treat amblyopia in children 4 to 5 years old. The effect of patching was not separate from that of optical correction with a period of refractive adaptation. Thus, the improvement in visual acuity is a combined effect of spectacle wear and occlusion therapy. Copyright (c) 2010 American Academy of Ophthalmology. Published by Elsevier Inc.

Personality traits inventory in patients with vocal nodules.
Mattei, Alexia; Revis, Joana; Giovanni, Antoine
2017-04-01
The objective of the study was to analyze temperament and character in females with vocal nodules (VN) compared to a vocally healthy control population. 61 females were examined over a 17-month period for dysphonia with VN (mean age 46 years, duration of vocal complaints from 2 months to 6 years). 71 control females were recruited in their environment (mean age 34 years). The validated French Version of the Temperament and Character Inventory (TCI) was used. Patients with VN had significantly (p < 0,05) greater scores for Persistence and Novelty Seeking, particularly for the subscales exploratory excitability and extravagance. They had lower scores for Harm Avoidance, in particular fear of uncertainty, shyness and fatigability. Scores on Reward Dependence were not significantly different except for the subscale dependence, which were significantly lower in patients. No significant difference was found with regard to scores on Self-directedness, except for scores on the subscale self-acceptance, which were significantly lower in patients. Scores on Cooperativeness were not significantly different, except for the subscale helpfulness, which were significantly higher in patients. Patients had significant greater scores for Self-transcendence overall and specifically on the subscales self-forgetfulness and spiritual acceptance. Our findings suggested that women with VN are likely to have a passionate temperament, which might constitute an indirect predisposition to elevated vocal loading and greater risk for phonotrauma. The risk for developing or maintaining VN could be decreased by attending to those personality-specific maladaptive behaviors. A possible personalized approach to voice therapy could be organized on the basis of the TCI findings.

To investigate macular retinal and choroidal thickness in amblyopic eyes compared to that in fellow and normal eyes using swept-source optical coherence tomography (SS-OCT). This study examined 31 patients with hyperopic anisometropic amblyopia (6.9 ± 3.8 years, mean ± standard deviation), 15 patients with strabismic amblyopia without anisometropia (7.9 ± 4.2 years), and 24 age-matched controls (7.8 ± 3.3 years). Retinal and choroidal thickness was measured by 3D scans using SS-OCT. A 6-mm area around the fovea was automatically analyzed using the Early Treatment Diabetic Retinopathy Study map. The thickness from SS-OCT was corrected for magnification error using individual axial length, spherical refraction, cylinder refraction, and corneal radius. Retinal thickness was divided into the macular retinal nerve fiber layer (mRNFL), ganglion cell layer + inner plexiform layer (GCL+IPL), ganglion cell complex (GCC), and the inner limiting membrane to the retinal pigment epithelium (ILM-RPE) thickness. Retinal and choroidal thickness was compared among amblyopic, fellow, and normal eyes. In both amblyopia groups, there was no significant difference in the mRNFL, GCL+IPL, and GCC thicknesses among the amblyopic, fellow, and control eyes. In the anisometropic amblyopia group, choroidal thickness (subfovea, center 1 mm, nasal and inferior of the inner ring, nasal of the outer ring, and center 6 mm) of amblyopic eyes were significantly greater than that of fellow and normal eyes. In contrast, none of the choroidal thicknesses were significantly different among the investigated eyes in the strabismic amblyopia group. We found no significant difference in inner retinal thickness in patients with unilateral amblyopia. Although there were significant differences in choroidal thickness with hyperopic anisometropic amblyopia, there was no significant difference for the strabismic amblyopia. The discrepancy in choroidal thickness between the two types of amblyopia may be due to both differences in ocular size and underlying mechanism.

This study was conducted to determine the diversity of Hymenoptera on the different ages of oil palm namely plot 12, 9 and 5 years old. Sampling was carried out from November 2015 to February 2016 at Ladang Lekir, Perak using Malaise traps and Window trap. A total of 3052 individuals Hymenopteran consisting of 58 morphospecies and 35 subfamilies of 17 families were successfully collected. The most abundant species recorded was the Pimplinae.sp4 with 447 individuals (relative abundance, RA=14.51%). According to the plot, plot 9 years old have the highest reading for all three Peilou Equality Index (E'=0.983), Shannon Diversity Index (H'=3.939) and Simpson Diversity Index (D'=0.9795) with 55 species have been recorded. The t-tests showed that there were no significant difference in term of the diversity index (H') between palm plots 9 years old and 12 years old, while there were significant differences between the two plot (9 years old and 12 years old) with 5 old palm plot. The species accumulation curve showed that only 5 old palm plot nearly asymptotic. This study is expected to help the management to provide basic information for future research and as well, to develop and implement tools, methods, strategies in farm management practices of the oil palm plantations in Malaysia.

identification of the mandibular movement range is an important procedure in the evaluation of the stomatognathic system. However, there are few studies in children that focus on normal parameters or abnormalities. to determine the average range of mandibular movements in Brazilian children aged 6 to 12 years; to verify the difference between genders, in each age group, and between the different age groups: 6-8 years; 8.1-10 years; and 10.1-12 years. participants of the study were 240 healthy children selected among regular students from local schools of São Paulo State. The maximum mandibular opening, lateral excursion and protrusive movements, and deviation of the medium line, if present, were measured using a digital caliper. Student T test, Analysis of variance and Tukey test were considered significant for p < 0.05. the mean values observed in the studied sample were: 44.51mm for maximum mandibular opening; 7.71mm for lateral excursion to the right; 7.92mm for lateral excursion to the left; 7.45mm for protrusive movements. No statistical difference was observed between genders. There was a gradual increase in the range of mandibular movements, with significant differences mainly between the ages of 6-8 years and 10.1-12 years. during childhood the range of mandibular movements increases. Age should be considered in this analysis for a greater precision in the diagnosis.
Asymptomatic bacteriuria. Clinical significance and management.
Raz, Raul
2003-10-01
The clinical significance and management of asymptomatic bacteriuria (ASB) differs according to different groups of patients. ASB requires antibiotic treatment in pregnant women, children aged 5-6 years and prior to invasive genitourinary procedures. However, there is a consensus that ASB in the elderly, healthy school girls and young women, diabetic women and patients with indwelling catheters or intermittent catheterization has no clinical significance and antibiotic prescription is not indicated.

Purpose Since high myopia in the younger generation may differ etiologically from high myopia in older generations, we examined whether education-related parameters differ between high myopia in today´s school children and high pathological myopia in today´s elderly generation. Methods The investigation included the adult populations of the population-based Beijing Eye Study (BES) (3468 adults;mean age:64.6±9.8years;range:50–93years) and Central India Eye and Medical Study (CIEMS) (4711 adults;age:49.±13.2years;range:30–100years), and the children and teenager populations of the Shandong Children Eye Study (SCES) (6026 children;age:9.7±3.3years;range:4–18years;cycloplegic refractometry), Gobi Desert Children Eye Study (1565;age:11.9±3.5years;range:6–21 years;cycloplegic refractometry), Beijing Pediatric Eye Study (681 children;age:7.7±1.6years;range:5–13 years;non-cycloplegic refractometry,calculation of axial length to corneal curvature radius ratio), Beijing Children Eye Study (15066 children;age:13.2±3.4years;range:7–18years;non-cycloplegic refractometry), Beijing High School Teenager Eye Study (4677 children;age:16.9±0.7years;range:16–18years;non-cycloplegic refractometry). Results In the BES and CIEMS, educational level did not differ significantly between, or was significantly lower in the highly myopic group (myopic refractive error ≥6 diopters) than in the non-highly myopic group. In all non-adult study populations, higher prevalence of high myopia was significantly associated with higher degree of education related parameters such as attendance of high-level schools, and more time spent for indoors near work versus time spent outdoors. Conclusions Comparing associations of old or genetic high myopia in adults with new or acquired high myopia in school children revealed that education-related parameters did not show a clear association with old or genetic high myopia, while in contrast, new high myopia showed strong associations with education. It confirms previous studies that the two forms of high myopia not only differed in age of onset, but also in associations with education as well. The data support the notion of two types of high myopia. Future studies may assess whether the risk of pathologic myopic maculopathy and high myopia associated open-angle glaucoma differs between both types of high myopia. PMID:27152764

The effect on linear growth of daily long-term inhaled corticosteroid therapy in preschool-aged children with recurrent wheezing is controversial. We sought to determine the effect of daily inhaled corticosteroid given for 2 years on linear growth in preschool children with recurrent wheezing. Children aged 2 and 3 years with recurrent wheezing and positive modified Asthma Predictive Index scores were randomized to a 2-year treatment period of chlorofluorocarbon-delivered fluticasone propionate (176 μg/d) or masked placebo delivered through a valved chamber with a mask and then followed for 2 years off study medication. Height growth determined by means of stadiometry was compared between treatment groups. In the study cohort as a whole, the fluticasone group did not have significantly less linear growth than the placebo group (change in height from baseline difference, -0.2 cm; 95% CI, -1.1 to 0.6) 2 years after discontinuation of study treatment. In post hoc analyses children 2 years old who weighed less than 15 kg at enrollment and were treated with fluticasone had less linear growth compared with those treated with placebo (change in height from baseline difference, -1.6 cm; 95% CI, -2.8 to -0.4; P = .009). Linear growth was not significantly different in high-risk preschool-aged children with recurrent wheezing treated with 176 μg/d chlorofluorocarbon-delivered fluticasone compared with placebo 2 years after fluticasone is discontinued. However, post hoc subgroup analyses revealed that children who are younger in age and of lesser weight relative to the entire study cohort had significantly less linear growth, possibly because of a higher relative fluticasone exposure.

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

To assess the effect of acetazolamide (AZ) on different ocular vascular beds. In a prospective study, 32 healthy volunteers (16 male, 16 female) with a mean age of 23.9 ± 3.3 years (20-39 years) were included. Before and after intravenous administration of 1,000 mg AZ (single dose), ocular microcirculation parameters were measured every 20 min for 2 h. Retinal vessel diameters (VD) were measured by the retina vessel analyzer, blood flow (BF) in the neuroretinal rim by the laser doppler flowmeter according to Riva, and the parapapillary retinal BF by the scanning laser Doppler flowmeter. Additionally, the Langham ocular blood flow system was used to determine the ocular pulse amplitude (OPA) and the pulsatile ocular blood flow (pOBF). The measurements were correlated with systemic blood pressure (BP), ocular perfusion pressure (OPP), capillary base excess parameters and serum AZ levels. Arterial and venous VD were significantly increased by about 4-5% each. Papillary BF increased significantly about 40%. Parapapillary retinal flow dropped significantly about 19% (120 min). OPA and pOBF showed no statistically significant changes. BP showed no significant changes, and OPP was significantly increased. There were no correlations with pH or systemic perfusion parameters. AZ leads to a dilatation of retinal VD, to an increase of BF in the optic nerve head, and to a decrease of parapapillary retinal BF. The different BF changes in different vascular beds might be due to different regulatory mechanisms, steal effects, or different distributions of the carbonic anhydrase.

To measure whether the benefits of a single education and self management structured programme for people with newly diagnosed type 2 diabetes mellitus are sustained at three years. Three year follow-up of a multicentre cluster randomised controlled trial in primary care, with randomisation at practice level. 207 general practices in 13 primary care sites in the United Kingdom. 731 of the 824 participants included in the original trial were eligible for follow-up. Biomedical data were collected on 604 (82.6%) and questionnaire data on 513 (70.1%) participants. A structured group education programme for six hours delivered in the community by two trained healthcare professional educators compared with usual care. The primary outcome was glycated haemoglobin (HbA(1c)) levels. The secondary outcomes were blood pressure, weight, blood lipid levels, smoking status, physical activity, quality of life, beliefs about illness, depression, emotional impact of diabetes, and drug use at three years. HbA(1c) levels at three years had decreased in both groups. After adjusting for baseline and cluster the difference was not significant (difference -0.02, 95% confidence interval -0.22 to 0.17). The groups did not differ for the other biomedical and lifestyle outcomes and drug use. The significant benefits in the intervention group across four out of five health beliefs seen at 12 months were sustained at three years (P<0.01). Depression scores and quality of life did not differ at three years. A single programme for people with newly diagnosed type 2 diabetes mellitus showed no difference in biomedical or lifestyle outcomes at three years although there were sustained improvements in some illness beliefs.

Objectives. To determine the prevalence, the clinical predictors, and the prognostic significances of Worsening Renal Function (WRF) in hospitalized patients with Acute Heart Failure (AHF). Methods. 394 consecutively hospitalized patients with AHF were evaluated. WRF was defined as an increase in serum creatinine of ≥0.3 mg/dL from baseline to discharge. Results. Nearly 11% of patients developed WRF. The independent predictors of WRF analyzed with a multivariable logistic regression were history of chronic kidney disease (P = .047), age >75 years (P = .049), and admission heart rates ≥100 bpm (P = .004). Mortality or rehospitalization rates at 1 month, 6 months, and 1year were not significantly different between patients with WRF and those without WRF. Conclusion. Different clinical predictors at hospital admission can be used to identify patients at increased risk for developing WRF. Patients with WRF compared with those without WRF experienced no significant differences in hospital length of stay, mortality, or rehospitalization rates.

1976-01-01
Thirty-five individuals aged 17 to 24 in whom severe chronic hyperactivity had been diagnosed 10 years before were studied together with 25 matched controls. There were no significant differences in mean height or weight or in electroencephalographic findings, but the mean pulse rate was significantly higher in the hyperactive group. Cognitive style tests indicated continued difficulty in reflection (resulting in more errors) but less impulsivity (longer reaction time) in the hyperactive individuals. Compared with controls, hyperactive subjects were continuing to have more scholastic difficulty, although this difference seemed to be less pronounced than 5 years before. Their adjustment in work situations and living arrangements did not differ significantly from that of the controls. Restlessness, both reported and observed, continued to be a problem for the hyperactive individuals, and socialization skills and sense of well-being continued to be poorer than in the controls. The hyperactive individuals did not show significantly more antisocial behaviour, nonmedical use of drugs or serious psychiatric disturbances. PMID:974949

To evaluate the impact of the Affordable Care Act's (ACA) dependent coverage mandate on insurance coverage among young adults in metropolitan and nonmetropolitan areas. A cross-sectional analysis was conducted using data from 2006-2009 and 2011 waves of the Medical Expenditure Panel Survey. A difference-in-difference analysis was used to compare changes in full-year private health insurance coverage among young adults aged 19-25 years with an older cohort aged 27-34 years. Separate regressions were estimated for individuals in metropolitan and nonmetropolitan areas and were tested for a differential impact by area of residence. Full-year private health insurance coverage significantly increased by 9.2 percentage points for young adults compared to the older cohort after the ACA mandate (P = .00). When stratifying the regression model by residence area, insurance coverage among young adults significantly increased by 9.0 percentage points in metropolitan areas (P = .00) and 10.1 percentage points in nonmetropolitan areas (P = .03). These changes were not significantly different from each other (P = .82), which suggests the ACA mandate's effects were not statistically different by area of residence. Although young adults in metropolitan and nonmetropolitan areas experienced increased access to private health insurance following the ACA's dependent coverage mandate, it did not appear to directly impact rural-urban disparities in health insurance coverage. Despite residents in both areas gaining insurance coverage, over one-third of young adults still lacked access to full-year health insurance coverage. © 2016 National Rural Health Association.

Background Preterm birth confers a high risk of adverse long term health outcomes for survivors, yet the underlying molecular mechanisms are unclear. We hypothesized that effects of preterm birth can be mediated through measurable epigenomic changes throughout development. We therefore used a longitudinal birth cohort to measure the epigenetic mark of DNA methylation at birth and 18 years comparing survivors of extremely preterm birth with infants born at term. Methods Using 12 extreme preterm birth cases and 12 matched, term controls, we extracted DNA from archived neonatal blood spots and blood collected in a similar way at 18 years of age. DNA methylation was measured at 347,789 autosomal locations throughout the genome using Infinium HM450 arrays. Representative methylation differences were confirmed by Sequenom MassArray EpiTYPER. Results At birth we found 1,555 sites with significant differences in methylation between term and preterm babies. At 18 years of age, these differences had largely resolved, suggesting that DNA methylation differences at birth are mainly driven by factors relating to gestational age, such as cell composition and/or maturity. Using matched longitudinal samples, we found evidence for an epigenetic legacy associated with preterm birth, identifying persistent methylation differences at ten genomic loci. Longitudinal comparisons of DNA methylation at birth and 18 years uncovered a significant overlap between sites that were differentially-methylated at birth and those that changed with age. However, we note that overlapping sites may either differ in the same (300/1,555) or opposite (431/1,555) direction during gestation and aging respectively. Conclusions We present evidence for widespread methylation differences between extreme preterm and term infants at birth that are largely resolved by 18 years of age. These results are consistent with methylation changes associated with blood cell development, cellular composition, immune induction and age at these time points. Finally, we identified ten probes significantly associated with preterm individuals and with greater than 5% methylation discordance at birth and 18 years that may reflect a long term epigenetic legacy of preterm birth.

Objective: To analyze the resting energy expenditure and optimal energy supply in different age groups of critically ill children on mechanical ventilation in pediatric intensive care unit (PICU). Methods: Patients on mechanical ventilation hospitalized in PICU of Beijing Children's Hospital from March 2015 to March 2016 were enrolled prospectively. Resting energy expenditure of patients was calculated by US Med Graphic company critical care management (CCM) energy metabolism test system after mechanical ventilation. Patients were divided into three groups:<3 years, 3-10 years, and >10 years. The relationship between the measured and predictive resting energy expenditure was analyzed with correlation analysis; while the metabolism status and the optimal energy supply in different age groups were analyzed with chi square test and variance analysis. Results: A total of 102 patients were enrolled, the measured resting energy expenditure all correlated with predictive resting energy expenditure in different age groups (<3 years ( r= 0.3, P= 0.0) ; 3~10 years ( r= 0.6, P= 0.0) ;>10 years ( r= 0.5, P= 0.0) ) . A total of 40 cases in < 3 years group, including: 14 cases of low metabolism (35%), 14 cases of normal metabolism (35%), and 12 cases of high metabolism (30%); 45 cases in 3-10 years group, including: 22 cases of low metabolism (49%), 19 cases of normal metabolism (42%), 4 cases of high metabolism (9%); 17 cases in > 10 years group, including: 12 cases of low metabolism (71%), 4 cases of normal metabolism (23%), 1 case of high metabolism (6%). Metabolism status showed significant differences between different age groups ( χ (2)=11.30, P <0.01, r= -0.01). Infants had higher metabolic status, which lessened with aging. The total average actual energy requirement was (210±84) kJ/ (kg⋅d) . There were significant differences in actual energy requirement between age groups ( F= 46.57, P< 0.001), with (277±77) kJ/ (kg⋅d) in < 3 years group, (184±53) kJ/ (kg⋅d) in 3-10 years group, and (120±30) kJ/ (kg⋅d) in > 10 years group. Conclusion: The resting energy metabolism of the critically ill children on mechanical ventilation is negatively related to the age. The actual energy requirement should be calculated according to different ages.

Aim: To study the effectiveness of the addition of citicoline to patching in the treatment of amblyopia in the age group of 4-13 years. Materials and Methods: A randomized controlled trial, which included patients who were randomly divided into two groups. Both the groups received patching therapy till plateau was achieved in phase 1 of the study. Then in phase 2, group I received citicoline plus patching and group II continued to receive only patching. Outcome Measures: Outcome was measured by the visual acuity in logMAR every month in phase 1 till plateau was achieved and then for 12 months in phase 2. Results: No significant difference was found in the mean visual acuities in these two groups in phase 1 till plateau was reached. In phase 2, for the initial four months, there was no significant difference in the visual acuities in these two groups, at the respective intervals. However, five months onward, up to 12 months, there was a significant difference in the visual acuities in these groups. The result was the same in younger patients (< seven years of age) as well as in older patients (> seven years of age). In phase 2, the mean proportional improvement in group I was significantly more than that in group II, at two months and onward, at the respective intervals. Conclusion: The improvement in visual acuity with citicoline plus patching was significantly more than that with patching alone, in one year of treatment. PMID:24618483

The aim of this case-control study was to assess sella turcica area and skeletal maturity in children with unilateral cleft lip and palate (UCLP) and compare with those of non-cleft children. A total of 85 UCLP patients aged 7.5-17.08 years (Group 1: age 7-11 years, Group 2: age 11-14 years and Group 3: age 14-18 years) were compared with 85 control subjects without clefts who were divided into similar age groups. Hand-wrist radiographs and cervical vertebra maturation stages (CVMS) were used to evaluate growth. Lateral cephalograms were traced, and reference points of sella were determined. Sella turcica area was measured using a digital planimeter. Comparison of overall growth on hand-wrist radiographs revealed no significant difference between cleft and non-cleft subjects. However, according to the chronological age groups, Group 1-UCLP showed statistically significant delay in skeletal maturation when compared with the age-matched control subjects (P = .05). This difference was due to the delay among male subjects (P = .05). As for CVMS, more significant maturation delay was observed in Group 1-UCLP (P = .001) and was attributable to both male and female subjects (P = .05). Comparison of sella turcica area showed no significant difference between UCLP patients and controls. Although children with CLP showed significant delay in growth when they are younger compared with the non-cleft children, sella turcica area measurements were similar for individuals in both groups. © 2018 John Wiley & Sons A/S.

This article presents the 2-year findings of a prospective investigation of the precursors to the later development of an eating disorder in adolescents. The sample consisted of 852 girls and 815 boys who began to study in Grades 7-10 and participated for 3 consecutive years. For both genders, the strongest predictors of Year 3 risk status were Years 1 and 2 risk scores. When the effects of Year 1 and Year 2 risk were controlled, race (Caucasian) and poor interoceptive awareness at Year 2 were significant predictors of disordered eating at Year 3 for girls. Previous risk status was the only significant predictor of Year 3 risk for boys. Gender difference evaluations in the risk score components indicated that a significantly greater proportion of girls than boys endorsed behaviors that were similar to eating disorder diagnostic criteria. Poor interoceptive awareness may provide a vulnerability for eating disorders; possible pathways were discussed.

Earlier studies have demonstrated disparities in patients undergoing left ventricular assist device (LVAD) implantation when stratified according to sex and race. Because very few data exist from large investigations, we reviewed data from the registry of the Mechanical Circulatory Support Research Network. Between May 2004 and September 2014, 734 patients underwent primary LVAD implantation at our institutions. Median age at implant was 57 (range 18 to 82) years and there were 577 males (80%). Race included Caucasian (C) in 586 patients (82%), African-American (AA) in 112 (16%), and other (O) in 21 (3%). Between sexes, significant pre-operative differences most commonly included median age at implant (males 60 years, females 57 years), ischemic etiology (53% vs 35%) and mean INTERMACS profile (2.9 vs 2.5). Between races, significant pre-operative differences most commonly included median age at implant (C = 61 vs AA = 51 vs O = 51), New York Heart Association functional class (85% vs 100% vs 92%) and ischemic etiology (55% vs 24% vs 40%). There were no significant differences in survival at 1, 3 or 5 years by sex or race. Similarly, there were no differences in time-related freedom from stroke, drive-line infection, gastrointestinal bleeding or pump thrombus by sex or race. After controlling for differences, neither sex nor race was associated with survival (p = 0.09 and p = 0.18, respectively), stroke (p = 0.28 and p = 0.21), drive-line infection (p = 0.9 and p = 0.92), gastrointestinal bleed (p = 0.48 and p = 0.45) or pump thrombus (p = 0.99 and p = 0.8). In this large, multi-institutional analysis, although some pre-operative clinical characteristics varied, they did not translate into any significant differences in late survival or complications while on LVAD support.

To investigate variables (injury, position, performance, and pitching volume) that affect the career longevity of Major League Baseball pitchers. To be eligible, pitchers must have entered Major League Baseball between 1989 and 1992 without missing information for the variables on the website http://www.baseball-reference.com. The variables assessed were average innings pitched per year before and after age 25 years, earned run average, walks and hits divided by innings pitched, strikeout to walk ratio, pitching position, time on the disabled list, length of career, and starting and retirement age. We used analysis of variance to compare the differences between groups and a regression model to assess the relationship between variables before age 25 years and career length. Mean retirement age for the group was 31.74 (95% confidence interval 30.83-32.65) and mean career length was 10.97 (95% confidence interval, 10.02-11.92) years. Innings pitched after age 25 years increased slightly, but not significantly, from the number of innings pitched before age 25 years, 85.35 versus 74.25, P = .5063. Career earned run average was not significantly different after age 25 years compared with before age 25 years, 4.83 versus 5.58, respectively, P = .8834. Both strikeout to walk ratio, 1.55 to 1.77, P = .0022, and walks and hits divided by innings pitched, 1.63 to 1.50, P = .0339, improved significantly after age 25 years compared with before age 25 years. The position the player started and ended his career (starter or reliever) did not influence career length. Multiple regression analysis comparing the variables from before age 25 revealed only the number of innings pitched before age 25 were positively related to career length, R 2 = 0.1408, P < .0001. All other variables analyzed before age 25 years were not significantly related to career length. The only studied variable that had significant relationship, which was weak to low, with career length was innings pitched per year before age 25 years. All other variables analyzed before age 25 years were not significantly related to career length. Level IV, case series. Copyright © 2016 Arthroscopy Association of North America.

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

This longitudinal study aims to characterize longitudinal blood pressure (BP) trajectories from childhood and examine the impact of level-independent childhood BP trajectories on adult left ventricular hypertrophy (LVH) and remodeling patterns. The longitudinal cohort consisted of 1154 adults (787 whites and 367 blacks) who had repeated measurements of BP 4 to 15 times from childhood (4-19 years) to adulthood (20-51 years) and assessment of echocardiographic LV dimensions in adulthood. Model-estimated levels and linear slopes of BP at childhood age points were calculated in 1-year intervals using the growth curve parameters and their first derivatives, respectively. Linear and nonlinear curve parameters of BP showed significant race and sex differences from age 15 years onwards. Adults with LVH had higher long-term BP levels than adults with normal LVM in race-sex groups. Linear and nonlinear slope parameters of BP differed consistently and significantly between LVH and normal groups. Associations of level-independent linear slopes of systolic BP with adult LVH were significantly inverse (odds ratio=0.75-0.82; P =0.001-0.015) in preadolescent children of 4 to 9 years but significantly positive (odds ratio=1.29-1.46; P =0.001-0.008) in adolescents of 13 to 19 years, adjusting for covariates. These associations were consistent across race-sex groups. Of note, the association of childhood BP linear slopes with concentric LVH was significantly stronger than that with eccentric LVH during the adolescence period of 12 to 19 years. These observations indicate that the impact of BP trajectories on adult LVH and geometric patterns originates in childhood. Adolescence is a crucial period for the development of LVH in later life, which has implications for early prevention. © 2018 American Heart Association, Inc.

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

The purpose of this study was to examine differences in velopharyngeal structures between adults with repaired cleft palate and normal resonance and adults without cleft palate. Thirty-six English-speaking adults, including 6 adults (2 males and 4 females) with repaired cleft palate (M = 32.5 years of age, SD = 17.4 years) and 30 adults (15 males and 15 females) without cleft palate (M = 23.3 years of age, SD = 4.1 years), participated in the study. Fourteen velopharyngeal measures were obtained on magnetic resonance images and compared between groups (cleft and noncleft). After adjusting for body size and sex effects, there was a statistically significant difference between groups for 10 out of the 14 velopharyngeal measures. Compared to those without cleft palate, participants with repaired cleft palate had a significantly shorter hard palate height and length, shorter levator muscle length, shorter intravelar segment, more acute levator angles of origin, shorter and thinner velum, and greater pharyngeal depth. Although significant differences were evident in the cleft palate group, individuals displayed normal resonance. These findings suggest that a wide variability in velopharyngeal anatomy can occur in the presence of normal resonance, particularly for those with repaired cleft palate. Future research is needed to understand how anatomic variability impacts function, such as during speech.

Background: Anterior cruciate ligament (ACL) rupture is a significant injury in National Basketball Association (NBA) players. Hypotheses: NBA players undergoing ACL reconstruction (ACLR) have high rates of return to sport (RTS), with RTS the season following surgery, no difference in performance between pre- and postsurgery, and no difference in RTS rate or performance between cases (ACLR) and controls (no ACL tear). Study Design: Case-control. Methods: NBA players undergoing ACLR were evaluated. Matched controls for age, body mass index (BMI), position, and NBA experience were selected during the same years as those undergoing ACLR. RTS and performance were compared between cases and controls. Paired-sample Student t tests, chi-square, and linear regression analyses were performed for comparison of within- and between-group variables. Results: Fifty-eight NBA players underwent ACLR while in the NBA. Mean player age was 25.7 ± 3.5 years. Forty percent of ACL tears occurred in the fourth quarter. Fifty players (86%) RTS in the NBA, and 7 players (12%) RTS in the International Basketball Federation (FIBA) or D-league. Ninety-eight percent of players RTS in the NBA the season following ACLR (11.6 ± 4.1 months from injury). Two players (3.1%) required revision ACLR. Career length following ACLR was 4.3 ± 3.4 years. Performance upon RTS following surgery declined significantly (P < 0.05) regarding games per season; minutes, points, and rebounds per game; and field goal percentage. However, following the index year, controls’ performances declined significantly in games per season; points, rebounds, assists, blocks, and steals per game; and field goal and free throw percentage. Other than games per season, there was no significant difference between cases and controls. Conclusion: There is a high RTS rate in the NBA following ACLR. Nearly all players RTS the season following surgery. Performance significantly declined from preinjury level; however, this was not significantly different from controls. ACL re-tear rate was low. Clinical Relevance: There is a high RTS rate in the NBA after ACLR, with no difference in performance upon RTS compared with controls. PMID:24427434

In 74 women with polycystic ovary syndrome, treated for 4 years with metformin (MET) and diet, we prospectively assessed whether, and to what degree, weight loss, reduction of insulin resistance, and amelioration of coronary heart disease risk factors could be sustained. We hypothesized that response to MET-diet would not differ by pretreatment body mass index (BMI) classes <25 (normal), > or =25 to <30 (overweight), > or =30 to <40 (obese), and > or =40 (extremely obese). [table: see text] Metformin-diet was successful in producing stable approximately 8% weight reduction for all 4 years (trend P < .0001). Percentage of reductions in weight on MET-diet was significant (P < .05) and did not differ among the 3 highest BMI categories (> or =40, > or =30 to <40, > or =25 to <30), but were not significant in the normal-weight category (BMI, <25). On MET-diet, median homeostasis model assessment of insulin resistance (HOMA-IR) was 33% lower than entry at 1 year, 50% at 2 years, 51% at 3 years, and 50% at 4 years (trend, P < .0001). On MET-diet, median low-density lipoprotein cholesterol (LDL-C) was 6% lower than entry at year 1, 6% at year 2, 7% at year 3, and 11% at year 4 (trend P < .0001). On MET-diet, median high-density lipoprotein cholesterol (HDL-C) was 3% higher than entry at year 2, 8% higher at year 3, and 11% higher at year 4 (trend P < .0001). Percentage of reductions in HOMA-IR, LDL-C, triglyceride, and systolic blood pressure, and increments in HDL-C did not differ (P > .1) in the 4 BMI categories. By stepwise regression, weight loss was a significant (P < or = .01) positive explanatory variable for reduction in HOMA-IR for all 4 follow-up years. Metformin-diet in women with polycystic ovary syndrome effectively and safely reduces weight and LDL-C while raising HDL-C, and maintains these outcomes stable over 4 years.
Variations in statewide water quality of New Jersey streams, water years 1998-2009

Statistical analyses were conducted for six water-quality constituents measured at 371 surface-water-quality stations during water years 1998-2009 to determine changes in concentrations over time. This study examined year-round concentrations of total dissolved solids, dissolved nitrite plus nitrate, dissolved phosphorus, total phosphorus, and total nitrogen; concentrations of dissolved chloride were measured only from January to March. All the water-quality data analyzed were collected by the New Jersey Department of Environmental Protection and the U.S. Geological Survey as part of the cooperative Ambient Surface-Water-Quality Monitoring Network. Stations were divided into groups according to the 1-year or 2-year period that the stations were part of the Ambient Surface-Water-Quality Monitoring Network. Data were obtained from the eight groups of Statewide Status stations for water years 1998, 1999, 2000, 2001-02, 2003-04, 2005-06, 2007-08, and 2009. The data from each group were compared to the data from each of the other groups and to baseline data obtained from Background stations unaffected by human activity that were sampled during the same time periods. The Kruskal-Wallis test was used to determine whether median concentrations of a selected water-quality constituent measured in a particular 1-year or 2-year group were different from those measured in other 1-year or 2-year groups. If the median concentrations were found to differ among years or groups of years, then Tukey's multiple comparison test on ranks was used to identify those years with different or equal concentrations of water-quality constituents. A significance level of 0.05 was selected to indicate significant changes in median concentrations of water-quality constituents. More variations in the median concentrations of water-quality constituents were observed at Statewide Status stations (randomly chosen stations scattered throughout the State of New Jersey) than at Background stations (control stations that are located on reaches of streams relatively unaffected by human activity) during water years 1998-2009. Results of tests on concentrations of total dissolved solids, dissolved chloride, dissolved nitrite plus nitrate, total phosphorus, and total nitrogen indicate a significant difference in water quality at Statewide Status stations but not at Background stations during the study period. Excluding water year 2009, all significant changes that were observed in the median concentrations were ultimately increases, except for total phosphorus, which varied significantly but in an inconsistent pattern during water years 1998-2009. Streamflow data aided in the interpretation of the results for this study. Extreme values of water-quality constituents generally followed inverse patterns of streamflow. Low streamflow conditions helped explain elevated concentrations of several constituents during water years 2001-02. During extreme drought conditions in 2002, maximum concentrations occurred for four of the six water-quality constituents examined in this study at Statewide Status stations (maximum concentration of 4,190 milligrams per liter of total dissolved solids) and three of six constituents at Background stations (maximum concentration of 179 milligrams per liter of total dissolved solids). The changes in water quality observed in this study parallel many of the findings from previous studies of trends in New Jersey.

The present study was conducted in 10 different communities of prefecture of Larissa, one of the main cotton-productive areas of Greece. Monitoring of Helicoverpa armigera lasted four years from 2002 to 2005. The monitoring system included four locations within each community and three traps in each location. Traps were of the funnel type, a reusable injection-moulded kind of plastic trap. Pheromone was z-11-hexadecenyl aldehyde 0.36% w/w. Insecticide (Vapona) was used for all the four years, but for years 2003 and 2004 double traps were used additionally, without the presence of insecticide (only with pheromone). Traps containing a pheromone and an insecticide had significantly greater number of insects trapped than those containing no insecticide. Fluctuation of insect population was different from year to year. Correlations on data between years (insect populations and cotton production across all communities) revealed that, when cotton production was low, the number of adult male insects of H. armigera captured in pheromone traps was high (r = -0.69). There were no statistically significant correlations between cotton production and number of trapped insects when data from all communities (across the four years) were used. Local conditions within each area have been proved important and these results were completely different compared to data concerning specific years. Prediction models must be used for average estimations within great areas that include data from many locations.
Learning styles and approaches to learning among medical undergraduates and postgraduates
2013-01-01
Background The challenge of imparting a large amount of knowledge within a limited time period in a way it is retained, remembered and effectively interpreted by a student is considerable. This has resulted in crucial changes in the field of medical education, with a shift from didactic teacher centered and subject based teaching to the use of interactive, problem based, student centered learning. This study tested the hypothesis that learning styles (visual, auditory, read/write and kinesthetic) and approaches to learning (deep, strategic and superficial) differ among first and final year undergraduate medical students, and postgraduates medical trainees. Methods We used self administered VARK and ASSIST questionnaires to assess the differences in learning styles and approaches to learning among medical undergraduates of the University of Colombo and postgraduate trainees of the Postgraduate Institute of Medicine, Colombo. Results A total of 147 participated: 73 (49.7%) first year students, 40 (27.2%) final year students and 34(23.1%) postgraduate students. The majority (69.9%) of first year students had multimodal learning styles. Among final year students, the majority (67.5%) had multimodal learning styles, and among postgraduates, the majority were unimodal (52.9%) learners. Among all three groups, the predominant approach to learning was strategic. Postgraduates had significant higher mean scores for deep and strategic approaches than first years or final years (p < 0.05). Mean scores for the superficial approach did not differ significantly between groups. Conclusions The learning approaches suggest a positive shift towards deep and strategic learning in postgraduate students. However a similar difference was not observed in undergraduate students from first year to final year, suggesting that their curriculum may not have influenced learning methodology over a five year period.

The effects of toothbrushing (B) and thermocycling (TC) on the surface texture of different materials with various fabrication processes have been investigated. However, studies of computer-aided design and computer-aided manufacturing (CAD-CAM) ceramic restorations are limited. The purpose of this in vitro study was to evaluate the effect of B and TC on the color stability and surface roughness of extrinsically characterized and glazed CAD-CAM ceramic restorations. Lithium disilicate CAD ceramic (n=90) and zirconia ceramic (n=90) were studied. All specimens were crystallized/sintered, characterized, and glazed following the manufacturer's recommendation. The specimens were divided into 9 different groups: B, TC, and a combination of B plus TC (B+TC). Brushing was performed at 50 000, 100 000, and 150 000 cycles, simulating an oral environment of 5, 10, and 15 years. Thermocycling was performed at 6000, 12 000, and 18 000 cycles, simulating an oral environment of 5, 10, and 15 years. Brushing plus TC was performed with the combination of the 50 000 cycles of B, then 6000 cycles of TC, and 10 000 cycles of B, then 12 000 cycles of TC, and 15 000 cycles of B, then 18 000 cycles of TC. The color and surface roughness of each specimen were measured before and after all interventions with simulated cycles. Color differences (ΔE) and surface roughness (ΔR a ) data were analyzed using 2-way ANOVA, followed by the least significant difference test (α=.05). The correlation between ΔE and ΔR a was statistically analyzed using the Pearson correlation analysis. Within the lithium disilicate CAD groups, intervention did not result in any significant differences in color change (P>.05). Within the zirconia groups, a 15-year clinical simulation revealed significantly higher ΔE values than a simulated 5-year exposure (P=.017). Increased simulated cycles showed significantly higher R a values for all groups. Within the zirconia groups, B revealed significantly smoother surfaces than TC (P<.001) and B+TC interventions (P<.001). For the zirconia, simulating B+TC for15 years revealed significantly higher R a values than the groups of B+TC for 5 years (P<.001) and B+TC for 10 years (P=.003). No correlation (lithium disilicate CAD, r=.079; P=.462; zirconia, r=.001; P=.989) was found between the color change and surface roughness. For both lithium disilicate CAD and zirconia, color changes were below the selected clinical perceptible threshold (ΔE=2.6) after all intervention and simulated cycles. All mean surface roughness measurements were below 0.2 μm. Generally, the surface of both lithium disilicate CAD and zirconia became rougher. No correlation was found between color difference and surface roughness for either material. Published by Elsevier Inc.

This study aimed to examine whether (a) exposure to universal newborn hearing screening (UNHS) and b) early confirmation of hearing loss were associated with benefits to expressive and receptive language outcomes in the teenage years for a cohort of spoken language users. It also aimed to determine whether either of these two variables was associated with benefits to relative language gain from middle childhood to adolescence within this cohort. The participants were drawn from a prospective cohort study of a population sample of children with bilateral permanent childhood hearing loss, who varied in their exposure to UNHS and who had previously had their language skills assessed at 6-10 years. Sixty deaf or hard of hearing teenagers who were spoken language users and a comparison group of 38 teenagers with normal hearing completed standardized measures of their receptive and expressive language ability at 13-19 years. Teenagers exposed to UNHS did not show significantly better expressive (adjusted mean difference, 0.40; 95% confidence interval [CI], -0.26 to 1.05; d = 0.32) or receptive (adjusted mean difference, 0.68; 95% CI, -0.56 to 1.93; d = 0.28) language skills than those who were not. Those who had their hearing loss confirmed by 9 months of age did not show significantly better expressive (adjusted mean difference, 0.43; 95% CI, -0.20 to 1.05; d = 0.35) or receptive (adjusted mean difference, 0.95; 95% CI, -0.22 to 2.11; d = 0.42) language skills than those who had it confirmed later. In all cases, effect sizes were of small size and in favor of those exposed to UNHS or confirmed by 9 months. Subgroup analysis indicated larger beneficial effects of early confirmation for those deaf or hard of hearing teenagers without cochlear implants (N = 48; 80% of the sample), and these benefits were significant in the case of receptive language outcomes (adjusted mean difference, 1.55; 95% CI, 0.38 to 2.71; d = 0.78). Exposure to UNHS did not account for significant unique variance in any of the three language scores at 13-19 years beyond that accounted for by existing language scores at 6-10 years. Early confirmation accounted for significant unique variance in the expressive language information score at 13-19 years after adjusting for the corresponding score at 6-10 years (R change = 0.08, p = 0.03). This study found that while adolescent language scores were higher for deaf or hard of hearing teenagers exposed to UNHS and those who had their hearing loss confirmed by 9 months, these group differences were not significant within the whole sample. There was some evidence of a beneficial effect of early confirmation of hearing loss on relative expressive language gain from childhood to adolescence. Further examination of the effect of these variables on adolescent language outcomes in other cohorts would be valuable.

The purpose of this study was to examine the sex and age-related differences in performance in a draft-legal ultra-cycling event. Age-related changes in performance across years were investigated in the 24-hour draft-legal cycling event held in Schötz, Switzerland, between 2000 and 2011 using multi-level regression analyses including age, repeated participation and environmental temperatures as co-variables. For all finishers, the age of peak cycling performance decreased significantly (β = -0.273, p = 0.036) from 38 ± 10 to 35 ± 6 years in females but remained unchanged (β = -0.035, p = 0.906) at 41.0 ± 10.3 years in males. For the annual fastest females and males, the age of peak cycling performance remained unchanged at 37.3 ± 8.5 and 38.3 ± 5.4 years, respectively. For all female and male finishers, males improved significantly (β = 7.010, p = 0.006) the cycling distance from 497.8 ± 219.6 km to 546.7 ± 205.0 km whereas females (β = -0.085, p = 0.987) showed an unchanged performance of 593.7 ± 132.3 km. The mean cycling distance achieved by the male winners of 960.5 ± 51.9 km was significantly (p < 0.001) greater than the distance covered by the female winners with 769.7 ± 65.7 km but was not different between the sexes (p > 0.05). The sex difference in performance for the annual winners of 19.7 ± 7.8% remained unchanged across years (p > 0.05). The achieved cycling distance decreased in a curvilinear manner with advancing age. There was a significant age effect (F = 28.4, p < 0.0001) for cycling performance where the fastest cyclists were in age group 35-39 years. In this 24-h cycling draft-legal event, performance in females remained unchanged while their age of peak cycling performance decreased and performance in males improved while their age of peak cycling performance remained unchanged. The annual fastest females and males were 37.3 ± 8.5 and 38.3 ± 5.4 years old, respectively. The sex difference for the fastest finishers was ~20%. It seems that women were not able to profit from drafting to improve their ultra-cycling performance.
Hierarchical model analysis of the Atlantic Flyway Breeding Waterfowl Survey

We used log-linear hierarchical models to analyze data from the Atlantic Flyway Breeding Waterfowl Survey. The survey has been conducted by state biologists each year since 1989 in the northeastern United States from Virginia north to New Hampshire and Vermont. Although yearly population estimates from the survey are used by the United States Fish and Wildlife Service for estimating regional waterfowl population status for mallards (Anas platyrhynchos), black ducks (Anas rubripes), wood ducks (Aix sponsa), and Canada geese (Branta canadensis), they are not routinely adjusted to control for time of day effects and other survey design issues. The hierarchical model analysis permits estimation of year effects and population change while accommodating the repeated sampling of plots and controlling for time of day effects in counting. We compared population estimates from the current stratified random sample analysis to population estimates from hierarchical models with alternative model structures that describe year to year changes as random year effects, a trend with random year effects, or year effects modeled as 1-year differences. Patterns of population change from the hierarchical model results generally were similar to the patterns described by stratified random sample estimates, but significant visibility differences occurred between twilight to midday counts in all species. Controlling for the effects of time of day resulted in larger population estimates for all species in the hierarchical model analysis relative to the stratified random sample analysis. The hierarchical models also provided a convenient means of estimating population trend as derived statistics from the analysis. We detected significant declines in mallard and American black ducks and significant increases in wood ducks and Canada geese, a trend that had not been significant for 3 of these 4 species in the prior analysis. We recommend using hierarchical models for analysis of the Atlantic Flyway Breeding Waterfowl Survey.
Comparative study of millennials' (age 20-34 years) grip and lateral pinch with the norms.
Fain, Elizabeth; Weatherford, Cara
Cross-sectional research design. Clinical practice continues to use normative data for grip and pinch measurements that were established in 1985. There is no updated norms despite different hand usage patterns in today's society. Measuring and comparing grip and pinch strengths with normative data is a valid method to determine hand function. This research was implemented to compare the grip and pinch measurements obtained from healthy millennials to the established norms and to describe hand usage patterns for millennials. Grip and lateral pinch measurements were obtained from a sample of 237 healthy millennials (ages 20-34 years). Strength scores were statistically lower that older normative data in all millennial grip strengths, with the exception of the women in the age group of 30-34 years. Specifically, this statistically significant trend was observed in all male grip strengths, as well as in women in the age group of 20-24 years (bilateral grip) and 25-29 years (right grip). However, the lateral pinch data reflected was similar to the older norms with variances of 0.5-1 kg. Current data reflect statistically significant differences from the norms for all male grip measurements, as well as for women in the age group of 20-24 years (bilateral grip) and 25-29 years (right grip). No statistical significance was observed in the independent-sample t tests for the lateral pinch in men of all age groups. Statistical significance was noted for lateral pinch for female age groups for the left hand (20-24 years) and for bilateral lateral pinches (30-34 years). IV. Copyright © 2016 Hanley & Belfus.

Background: Thyroid cancer is unique for having age as a staging variable. Recently, the commonly used age cut-point of 45 years has been questioned. Objective: This study assessed alternate staging systems on the outcome of overall survival, and compared these with current National Thyroid Cancer Treatment Cooperative Study (NTCTCS) staging systems for papillary and follicular thyroid cancer. Methods: A total of 4721 patients with differentiated thyroid cancer were assessed. Five potential alternate staging systems were generated at age cut-points in five-year increments from 35 to 70 years, and tested for model discrimination (Harrell's C-statistic) and calibration (R2). The best five models for papillary and follicular cancer were further tested with bootstrap resampling and significance testing for discrimination. Results: The best five alternate papillary cancer systems had age cut-points of 45–50 years, with the highest scoring model using 50 years. No significant difference in C-statistic was found between the best alternate and current NTCTCS systems (p = 0.200). The best five alternate follicular cancer systems had age cut-points of 50–55 years, with the highest scoring model using 50 years. All five best alternate staging systems performed better compared with the current system (p = 0.003–0.035). There was no significant difference in discrimination between the best alternate system (cut-point age 50 years) and the best system of cut-point age 45 years (p = 0.197). Conclusions: No alternate papillary cancer systems assessed were significantly better than the current system. New alternate staging systems for follicular cancer appear to be better than the current NTCTCS system, although they require external validation. PMID:26203804

Oral diseases are a health problem worldwide. Differences in oral health status may vary with geographical locations, but also within the same country and between groups with different social backgrounds. The specific aims were to describe secular trends in oral health status regarding number of remaining teeth and also to describe differences in socio-economic status, among 38- and 50-year-old women, over a 36-year period. Cross-sectional health surveys were performed at four occasions; 1968/69 (n = 746), 1980/81 (n = 532), 1992/93 (n = 165) and 2004/05 (n = 500), including randomly selected women aged 38 and 50 years. The number of teeth was determined using panoramic radiographs and self-reported measures of marital status, social class, educational level, and income were recorded. The mean number of teeth among women has increased significantly. The educational level has increased while fewer women are married/cohabiting over time. There has been a shift in the social group the women belong to, where proportionally more women were categorized in a higher social group in 2004/05 than in 1968/69. Moreover, there is a significant relationship between fewer teeth and a lower social group, and among the 50-year-old women, this was irrespective of examination year. However, multivariate analyses showed that the risk to be edentulous or not, or to have fewer remaining teeth was significantly higher for women of lower social group, or living alone, in all studies over the 36 year-period. This was independent of age group, even though the risk diminished over the study period. Cohort comparisons of women aged 38 and 50 years during 36 years showed that dental status improved, with (i) a decreasing prevalence of edentulism and, (ii) an increasing number of remaining teeth in dentate individuals over time. Differences due to social group and education were still present, with more remaining teeth in the women in the higher social group. A time trend analysis indicated that in the later examination years the individuals had fewer teeth lost, irrespective of age, marital status and, social group.

Aim of this retrospective study was to compare soft tissue effects of Class II treatments with the forsus fatigue resistant device (FRD), the pendulum appliance, and the extraction of two maxillary premolars, all of which were combined with pre-adjusted fixed appliances. The sample of 54 patients with Class II malocclusions was divided in three groups: group I patients (mean age = 15.91 years) were treated with the FRD concurrently used with fixed appliances; group II patients (mean age = 16.08 years) were treated with the pendulum appliance combined with a Nance and headgear followed by fixed appliances; and group III patients (mean age = 19.04 years) were treated with the extraction of two maxillary premolars with miniscrew anchorage. Soft tissue and dentoskeletal parameters were measured on pretreatment (T1) and posttreatment (T2) lateral cephalograms. The changes from T1 to T2 were compared between the groups using Kruskal-Wallis test, and treatment differences were evaluated with the Wilcoxon test at p < 0.05. Soft tissue measurement changes related to the upper and lower lips were significantly greater in group II than in group III (p < 0.05). Upper incisor measurement changes were significantly different between groups II and III. Lower incisor measurement changes were significantly different between groups I and III and groups II and III (p < 0.05). Pendulum and extraction treatment groups showed significant differences in relation with the upper and lower lip positional changes, which were significantly greater in the pendulum group. Treatment time with the extraction treatment was statistically shorter than with the nonextraction protocols.

In Mozambique, schistosomiasis is highly endemic across the whole country. The Schistosomiasis Consortium for Operational Research and Evaluation (SCORE) coordinates a five-year study that has been implemented in various African countries, including Mozambique. The overall goal of SCORE was to better understand how to best apply preventive chemotherapy with praziquantel (PZQ) for schistosomiasis control by evaluating the impact of alternative treatment approaches. This was a cluster-randomised trial that compared the impact of different treatment strategies in study areas with prevalence among school children of ≥21% S. haematobium infection by urine dipstick. Each village was randomly allocated to one of six possible combinations of community-wide treatment (CWT), school-based treatment (SBT), and/or drug holidays over a period of four years, followed by final data collection in the fifth year. The most intense intervention arm involved four years of CWT, while the least intensive arm involved two years of SBT followed by two consecutive years of PZQ holiday. Each study arm included 25 villages randomly assigned to one of the six treatment arms. The primary outcome of interest was change in prevalence and intensity of S. haematobium among 100 children aged 9-to-12-years that were sampled each year in every village. In addition to children aged 9-to-12 years, 100 children aged 5-8 years in their first-year of school and 50 adults (aged 20-55 years) were tested in the first and final fifth year of the study. Prevalence and intensity of S. haematobium infection was evaluated by two filtrations, each of 10mL, from a single urine specimen. In total, data was collected from 81,167 individuals across 149 villages in ten districts of Cabo Delgado province, Northern Mozambique. Overall PZQ treatment resulted in a significant reduction in the prevalence of S. haematobium infection from Year 1 to Year 5, where the average prevalence went from 60.5% to 38.8%, across all age groups and treatment arms. The proportion of those heavily infected also reduced from 17.6% to 11.9% over five years. There was a significantly higher likelihood of males being infected than females at baseline, but no significant difference between the sexes in their response to treatment. The only significant response based on a study arm was seen in both the 9-to-12-year-old and first-year cross sections, where two consecutive treatment holidays resulted in a significantly higher final prevalence of S. haematobium than no treatment holidays. When the arms were grouped together, four rounds of treatment (regardless of whether it was CWT or SBT), however, did result in a significantly greater reduction in S. haematobium prevalence than two rounds of treatment (i.e. with two intermittent or consecutive holiday years) over a five-year period. Although PC was successful in reducing the burden of active infection, even among those heavily infected, annual CWT did not have a significantly greater impact on disease prevalence or intensity than less intense treatment arms. This may be due to extremely high starting prevalence and intensity in the study area, with frequent exposure to reinfection, or related to challenges in achieving high treatment coverage More frequent treatment had a greater impact on prevalence and intensity of infection when arms were grouped by number of treatments, however, cost efficiency was greater in arms only receiving two treatments. Finally, a significant reduction in prevalence of S. haematobium was seen in adults even in the SBT arms implying the rate of transmission in the community had been decreased, even where only school children have been treated, which has significant logistical and cost-saving implications for a national control programme in justifying CWT.

[Academic burnout and selection-optimization-compensation strategy in medical students].
Chun, Kyung Hee; Park, Young Soon; Lee, Young Hwan; Kim, Seong Yong
2014-12-01
This study was conducted to examine the relationship between academic demand, academic burnout, and the selection-optimization-compensation (SOC) strategy in medical students. A total of 317 students at Yeungnam University, comprising 90 premedical course students, 114 medical course students, and 113 graduate course students, completed a survey that addressed the factors of academic burnout and the selection-optimization-compensation strategy. We analyzed variances of burnout and SOC strategy use by group, and stepwise multiple regression analysis was conducted. There were significant differences in emotional exhaustion and cynicism between groups and year in school. In the SOC strategy, there were no significant differences between groups except for elective selection. The second-year medical and graduate students experienced significantly greater exhaustion (p<0.001), and first-year premedical students experienced significantly higher cynicism (p<0.001). By multiple regression analysis, subfactors of academic burnout and emotional exhaustion were significantly affected by academic demand (p<0.001), and 46% of the variance was explained. Cynicism was significantly affected by elective selection (p<0.05), and inefficacy was significantly influenced by optimization (p<0.001). To improve adaptation, prescriptive strategies and preventive support should be implemented with regard to academic burnout in medical school. Longitudinal and qualitative studies on burnout must be conducted.

Aspergillus flavus frequently contaminates maize, a critical staple for billions of people, with aflatoxins. Diversity among A. flavus L morphotype populations associated with maize in Sonora, Mexico was assessed and, in total, 869 isolates from 83 fields were placed into 136 vegetative compatibility groups (VCGs) using nitrate-nonutilizing mutants. VCG diversity indices did not differ in four agroecosystems (AES) but diversity significantly differed among years. Frequencies of certain VCGs changed manyfold over single years in both multiple fields and multiple AES. Certain VCGs were highly frequent (>1%) in 2006 but frequencies declined repeatedly in each of the two subsequent years. Other VCGs that had low frequencies in 2006 increased in 2007 and subsequently declined. None of the VCGs were consistently associated with any AES. Fourteen VCGs were considered dominant in at least a single year. However, frequencies often varied significantly among years. Only 9% of VCGs were detected all 3 years whereas 66% were detected in only 1 year. Results suggest that the most realistic measurements of both genetic diversity and the frequency of A. flavus VCGs are obtained by sampling multiple locations in multiple years. Single-season sampling in many locations should not be substituted for sampling over multiple years.
In vitro fertilization outcomes in obese women under and above 35 years of age.
Vural, F; Vural, B; Çakiroglu, Y

To explore the impact of obesity on in vitro fertilization (IVF) outcomes and comparing the results with regards to age groups. This retrospective cohort recruited 780 women that underwent IVF. Women with polycystic ovarian syndrome (PCOS) were excluded from the study. Women under and above 35 years were categorized into three groups as normal weight, overweight, and obese. The main outcome measures were ovarian response, oocyte maturity, and clinical pregnancy rates. Despite oocyte count and fertilization rate that decreased in both younger and older obese women, this difference was not statistically significant. After age matched-normal weight controls, the clinical pregnancy rates were significantly decreased in older obese women. On the other hand, poor ovarian response observed significantly in young obese women without effect on pregnancy rates. These results suggested that obesity in young and old women has different outcomes and different steps of IVF process may be affected.

Two morphologically different cultivars of Italian melons (Baggio and Giusto) were characterized considering samples harvested in different times, at the beginning (BPP) and at the end of the physiological plant production period (EPP). Proximate composition, protein, minerals, pH, phenolic content, antioxidant capacity, ascorbic acid, carotenoids, condensed tannins, and flavonoids were measured, showing a significant decrease in EPP samples (phenolics, antioxidant capacity, condensed tannins, and flavonoids); ascorbic acid decreased in Giusto cv, carotenoids in Baggio cv. Mineral content increased in either the cultivars (EPP samples). Year-to-year difference was significantly highlighted; the plant growing cycle significantly affected the chemotype. Despite these effects, the Principal Component Analysis (PCA) permitted the discrimination of Baggio from Giusto cv, and the discrimination of BPP from EPP samples as well. © 2012 Institute of Food Technologists®
Blood alcohol concentration in drivers of Liege area (Belgium): a 5-year analysis.
Deville, M; Charlier, C
2015-10-01
The objective of the study was to describe 'the results of the blood alcohol determinations made on drivers from the Liege area between 2007 and 2012. The results were interpreted according to the sex, to the age, to the circumstances and temporal variation of the test. Statistical analysis was performed using R® software. 2725 determinations were done, mainly after crashes. The mean blood alcohol concentration (BAC) was 1.69 g/L, and 2132 drivers were above the legal threshold. A majority of offenders were men, but the mean BAC did not differ significantly between men and women. A correlation between age and mean BAC can be observed on the positive cases. Lowest and highest mean BACs are observed during the daytime and during the night, respectively, but no significant difference can be observed between the week and the weekend. Finally, no significant difference in BAC was observed over years.

Soil physic-chemical properties differ at different depths; however, differences in afforestation-induced temporal changes at different soil depths are seldom reported. By examining 19 parameters, the temporal changes and their interactions with soil depth in a large chronosequence dataset (159 plots; 636 profiles; 2544 samples) of larch plantations were checked by multivariate analysis of covariance (MANCOVA). No linear temporal changes were found in 9 parameters (N, K, N:P, available forms of N, P, K and ratios of N: available N, P: available P and K: available K), while marked linear changes were found in the rest 10 parameters. Four of them showed divergent temporal changes between surface and deep soils. At surface soils, changing rates were 262.1 g·kg(-1)·year(-1) for SOM, 438.9 mg·g(-1)·year(-1) for C:P, 5.3 mg·g(-1)·year(-1) for C:K, and -3.23 mg·cm(-3)·year(-1) for bulk density, while contrary tendencies were found in deeper soils. These divergences resulted in much moderated or no changes in the overall 80-cm soil profile. The other six parameters showed significant temporal changes for overall 0-80-cm soil profile (P: -4.10 mg·kg(-1)·year(-1); pH: -0.0061 unit·year(-1); C:N: 167.1 mg·g(-1)·year(-1); K:P: 371.5 mg·g(-1) year(-1); N:K: -0.242 mg·g(-1)·year(-1); EC: 0.169 μS·cm(-1)·year(-1)), but without significant differences at different soil depths (P > 0.05). Our findings highlight the importance of deep soils in studying physic-chemical changes of soil properties, and the temporal changes occurred in both surface and deep soils should be fully considered for forest management and soil nutrient balance.

In a cohort of 393 Chinese women, by using high-resolution peripheral quantitative computed tomography (HR-pQCT), we found that significant cortical bone loss occurred after midlife. Prominent increase in cortical porosity began at the fifth decade but reached a plateau before the sixth decade. Trabecular bone loss was already evident in young adulthood and continued throughout life. This study aimed to investigate age-related differences in volumetric bone mineral density (vBMD), microarchitecture, and estimated bone strength at peripheral skeleton in Chinese female population. In a cross-sectional cohort of 393 Chinese women aged 20-90 years, we obtained vBMD, microarchtecture, and micro-finite element-derived bone strength at distal radius and tibia using HR-pQCT. The largest predictive age-related difference was found for cortical porosity (Ct.Po) which showed over four-fold and two-fold differences at distal radius and tibia, respectively, over the adulthood. At both sites, cortical bone area, vBMD, and thickness showed significant quadratic association with age with significant decrease beginning after midlife. Change of Ct.Po became more prominent between age of 50 and 57 (0.26 %/year at distal radius, 0.54 %/year at distal tibia, both p ≤ 0.001) but thereafter, reached a plateau (0.015 and 0.028 %/year, both p > 0.05). In contrast, trabecular vBMD and microarchitecture showed linear association with age with significant deterioration observed throughout adulthood. Estimated age of peak was around age of 20 for trabecular vBMD and microarchitecture and Ct.Po and age of 40 for cortical vBMD and microarchitecture. Estimated stiffness and failure load peaked at mid-30s at the distal radius and at age 20 at distal tibia. Age-related differences in vBMD and microarchitecture in Chinese women differed by bone compartments. Significant cortical bone loss occurred after midlife. Prominent increase in Ct.Po began at the fifth decade but appeared to be arrested before the sixth decade. Loss of trabecular bone was already evident in young adulthood and continued throughout life.

Generalized anxiety disorder (GAD) peaks in prevalence in middle age and declines in prevalence into old age. Some commentators have suggested that this is not a meaningful epidemiological trend rather a methodological artifact. This study tested this hypothesis by matching respondents of different ages based on their severity and examining whether age influences the probability of endorsing GAD criteria and the prevalence of GAD. Self-reported worriers from a nationally representative survey of non-institutionalized adults were selected for investigation (n=1738). All respondents were interviewed using the World Mental Health version of the Composite International Diagnostic Interview. Age-related differences in the prevalence and invariance of the GAD criteria were examined between 16 and 29 years, 30 and 44 years, 45 and 59 years and 60 years+ age groups. Effect sizes were used to assess the impact of statistically significant criterion level non-invariance on the prevalence of GAD. Respondents aged 60 years or more were less likely than younger adults to endorse most of the GAD criteria. Significant non-invariance was identified in each of the age group analyses. Nonetheless these differences had no impact on the prevalence of GAD in three group comparisons. In the other three group comparisons, the impact was minimal (d ≤ 0.3). Our results support age-related differences in the prevalence of GAD but we are limited to the extent to which we can say why these differences occur. Age-related prevalence differences in GAD are meaningful epidemiological trends. © 2013 Published by Elsevier B.V.

Incidents of diphtheria in countries which were formerly part of the Soviet Union (Ukraine, Russia and Belorus) resulted in the need to evaluate thoroughly the effectiveness of preventive vaccination in Poland, especially in the border regions of the country where the biggest migration of population can be observed. The aim of this work was a comparison of the immunity to diphtheria in two geographically different regions of Poland--eastern (Lublin) and western (Zielona Gora) ones. It showed immunoprophylaxis to diphtheria that was implemented on these areas. Diphtheria antitoxin level (IgG) was determined with application of the ELISA method in 1236 (529/707) people. No significant differences were found in the level of antibodies in the groups < 2 years of age and > 19 years of age in people below the protective titre (0.1 IU/ml). The difference occurring in the interval between 2nd and 18th year of life (in western Poland 7.6% and in eastern Poland 16%) may result from different implementation of the vaccination program in these regions (booster doses). Recommendations for vaccination to diphtheria in people over 25 years of age should be implemented especially in the frontier regions of Poland adjoining countries threatened with diphtheria occurrence.

Background: Capitellar osteochondritis dissecans (OCD) in skeletally immature athletes has often been seen in baseball players and gymnasts. The choice of surgical procedure for unstable lesions in skeletally immature athletes remains controversial. Purpose: To investigate functional outcomes and radiographic changes in the midterm to long-term postoperative period after arthroscopic (AS) resection for small to large capitellar OCD lesions in skeletally immature athletes. Study Design: Case series; Level of evidence, 4. Methods: A total of 38 elbows in 38 patients (33 boys, 5 girls; mean age, 14 years [range, 13-15 years]) with skeletally immature elbows underwent AS resection for capitellar OCD. Patients were observed for at least 5 years (mean, 8 years [range, 5-12 years]). Elbows with a lesion width that did not exceed one-half of the radial head diameter were assigned to group 1 (n = 17 elbows), and larger lesions were assigned to group 2 (n = 21 elbows). Functional scores, patient satisfaction, range of motion (ROM), and osteoarthritis (OA) grades were evaluated between the groups. Results: All patients returned to sports activity. Functional scores at the final follow-up were not significantly different between the groups. Patient satisfaction scores were significantly higher in group 1 than in group 2. There was significant improvement in flexion ROM at the final follow-up compared with preoperative values in group 1 (P = .017), and there was a significant between-group difference (group 1: 141°; group 2: 133°; P = .002). Extension ROM showed significant improvement in both groups (group 1: from –8° to 3°; group 2: from –17° to –1°; P < .001 for both). Group 1 tended to have better extension than group 2, but the difference was not significant. There were no elbows with severe OA in either group, but the OA grade progressed in 5 elbows (29%) in group 1 and 9 elbows (43%) in group 2, and this rate of OA progression was statistically significant between groups (P = .005). Conclusion: Both functional outcomes and radiological findings after AS fragment resection were excellent in elbows with small lesions. Although overall outcomes were acceptable in elbows with larger lesions, flexion ROM and patient satisfaction scores were significantly inferior to those in elbows with smaller lesions. PMID:29276715

Susceptibility to environmental stressors has been described for fetal and early childhood development. However, the possible susceptibility of the prepubertal period, characterized by the orchestration of the organism towards sexual maturation and adulthood has been poorly investigated and exposure data are scarce. In the current study levels of cadmium (Cd), cotinine and creatinine in urine were analyzed in a subsample 216 children from 12 European countries within the DEMOCOPHES project. The children were divided into six age–sex groups: boys (6–8 years, 9–10 years and 11 years old), and girls (6–7 years, 8–9 years, 10–11 years). The number of subjects permore » group was between 23 and 53. The cut off values were set at 0.1 µg/L for Cd, and 0.8 µg/L for cotinine defined according to the highest limit of quantification. The levels of Cd and cotinine were adjusted for creatinine level. In the total subsample group, the median level of Cd was 0.180 µg/L (range 0.10–0.69 µg/L), and for cotinine the median wet weight value was 1.50 µg/L (range 0.80–39.91 µg/L). There was no significant difference in creatinine and cotinine levels between genders and age groups. There was a significant correlation between levels of cadmium and creatinine in all children of both genders. This shows that even at such low levels the possible effect of cadmium on kidney function was present and measurable. An increase in Cd levels was evident with age. Cadmium levels were significantly different between 6–7 year old girls, 11 year old boys and 10–11 year old girls. As there was a balanced distribution in the number of subjects from countries included in the study, bias due to data clustering was not probable. The impact of low Cd levels on kidney function and gender differences in Cd levels needs further investigation. - Highlights: • In 216 children from 6 to 11 years old the median level of Cd was 0.18 µg/L. • The median level of cotinine was 1.50 µg/L. • Correlation between levels of Cd and creatinine in all children was detected. • Cd levels were different between 6–7 year old, 10–11 year old girls vs. 11 year old boys.« less

1. Hemoglobin, packed cell volume, erythrocytes, leucocytes, MCV, MCH and MCHC were determined for a population of Marmota flaviventris over a period of seven years. 2. There was no significant difference in hematology among years, between sexes, or between seasons for adults and yearlings. 3. Early season juveniles had significantly lower PCV, Hb and erythrocyte counts than did late season juveniles. There were no significant differences in hematological values among adults, yearlings and late season juveniles. 4. Juveniles had significantly lower leucocycte counts than adults and yearlings. 5. PCV of marmots responds to acclimatization. 6. Hematological values of scuirids are adaptive to environmental factors such as hypoxia of burrows and high altitude, temperature and metabolic rate. 7. PCV of yellow-bellied marmots evidences an adaptive response to high altitude when compared to the closely-related woodchuck, M. monax.

Risk to predators hunting dangerous prey is an emerging area of research and could account for possible persistent differences in gray wolf (Canis lupus) pack sizes. We documented significant differences in long-term wolf-pack-size averages and variation in the Superior National Forest (SNF), Denali National Park and Preserve, Yellowstone National Park, and Yukon, Canada (p<0.01). The SNF differences could be related to the wolves’ risk when hunting primary prey, for those packs (N=3) hunting moose (Alces americanus) were significantly larger than those (N=10) hunting white-tailed deer (Odocoileus virginianus) (F1,8=16.50, p=0.004). Our data support the hypothesis that differential pack-size persistence may be perpetuated by differences in primary prey riskiness to wolves, and we highlight two important extensions of this idea: (1) the potential for wolves to provision and defend injured packmates from other wolves and (2) the importance of less-risky, buffer prey to pack-size persistence and year-to-year variation.

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

This study examined patterns in mammography and Pap test use across and within subpopulations of Hispanic women. Based on data from the National Health Interview Survey (2008, 2010, and 2013), we estimated the proportion of Hispanic women reporting testing for breast and cervical cancer for specific subgroups. We examined test use by demographic characteristics using Chi-square tests. Overall, the proportion of women aged 50-74 years who reported a mammogram within the past 2 years did not differ significantly across Hispanic subgroups. Among publically and uninsured women, however, proportions of mammography utilization varied significantly across Hispanic subgroups. The proportion of women aged 21-65 years who received a Pap test within the past 3 years differed significantly across Hispanic subgroups. Among subgroups of Hispanic women, patterns in mammography and Pap test use vary by insurance status, length of US residency, and type of screening. Certain subgroups of Hispanic women may benefit from culturally tailored efforts to promote breast and cervical cancer screening.

Summary Objective To determine the impact after two years of a water and health education (W/HE) program on ocular C. trachomatis infection and trachoma. Methods We randomized 12 trachoma-endemic communities in Maradi, Niger 1:1 to W/HE intervention and control arms and collected data on 10 of the 12 villages. In the intervention villages, at least one clean water well was constructed, and a three-month, modest health education program was provided immediately prior to the two year survey. We censused all households, and 557 children ages 1 to 5 years were randomly selected as sentinel children and examined at baseline and at one and two years from baseline. Trachoma was clinically assessed and a swab taken and analyzed for C. trachomatis. Tetracycline eye ointment was provided to all children in either arm during the surveys who had signs of trachoma. Results Infection with C. trachomatis declined slightly, and not significantly, in the children in the control villages over the two years, from 15% to 11%. The decline in infection was more pronounced, and significant, in the children in the intervention villages, from 26% to 15%. However, the change in infection rates in the intervention villages was not significantly different from the change in infection rates in the control villages (p=0.39, and 0.11 for change from baseline to one year and two year respectively). There was also no difference in the change in overall trachoma rates between the two arms. Conclusion These data suggest that the provision of water plus a modest health education program did not result in a significant difference in trachoma or ocular C. trachomatis infection in endemic communities in Niger. A more substantial health education intervention is likely necessary to produce change. PMID:20409284

Objective. To determine the accuracy of dose of pharmacy students’ parenteral sterile preparation skills and to measure pharmacy students’ skill retention 1.5 years later. Methods. An exercise was designed to assess each student’s accuracy in compounding a sterile preparation with the correct potency during a second and then third year course. Results. Initially, the mean (standard deviation) of 141 students’ compounded preparation dose was not significantly different than the desired dose. Additionally, 91.5% of products were within 10% of the desired dose. In the follow-up activity the next academic year, the mean dose was not significantly different than the original compounded dose. Similarly 92.9% were within 10% of the desired dose. Conclusion. Students’ overall accuracy of sterile compounding was good initially and well-retained more than a year later, with more than 90% of students being within 10% of the desired dose in both courses.

Individuals with documented disabilities may receive accommodations on the Medical College Admission Test (MCAT). Whether such accommodations are associated with MCAT scores, medical school admission, and medical school performance is unclear. To determine the comparability of MCAT scores obtained with standard vs extra administration time with respect to likelihood of acceptance to medical school and future medical student performance. Retrospective cohort study of applicants to US medical schools for the 2011-2013 entering classes who reported MCAT scores obtained with standard time (n = 133,962) vs extra time (n = 435), and of students who matriculated in US medical schools from 2000-2004 who reported MCAT scores obtained with standard time (n = 76,262) vs extra time (n = 449). Standard or extra administration time during MCAT. Primary outcome measures were acceptance rates at US medical schools and graduation rates within 4 or 5 years after matriculation. Secondary outcome measures were pass rates on the United States Medical Licensing Examination (USMLE) Step examinations and graduation rates within 6 to 8 years after matriculation. Acceptance rates were not significantly different for applicants who had MCAT scores obtained with standard vs extra time (44.5% [59,585/133,962] vs 43.9% [191/435]; difference, 0.6% [95% CI, -4.1 to 5.3]). Students who tested with extra time passed the Step examinations on first attempt at significantly lower rates (Step 1, 82.1% [344/419] vs 94.0% [70,188/74,668]; difference, 11.9% [95% CI, 9.6% to 14.2%]; Step 2 CK, 85.5% [349/408] vs 95.4% [70,476/73,866]; difference, 9.9% [95% CI, 7.8% to 11.9%]; Step 2 CS, 92.0% [288/313] vs 97.0% [60,039/61,882]; difference, 5.0% [95% CI, 3.1% to 6.9%]). They also graduated from medical school at significantly lower rates at different times (4 years, 67.2% [285/424] vs 86.1% [60,547/70,305]; difference, 18.9% [95% CI, 15.6% to 22.2%]; 5 years, 81.6% [346/424] vs 94.4% [66,369/70,305]; difference, 12.8% [95% CI, 10.6% to 15.0%]; 6 years, 85.4% [362/424] vs 95.8% [67,351/70,305]; difference, 10.4% [95% CI, 8.5% to 12.4%]; 7 years, 88.0% [373/424] vs 96.2% [67,639/70,305]; difference, 8.2% [95% CI, 6.4% to 10.1%]; 8 years, 88.4% [375/424] vs 96.5% [67,847/70,305]; difference, 8.1% [95% CI, 6.3% to 9.8%]). These differences remained after controlling for MCAT scores and undergraduate grade point averages. Among applicants to US medical schools, those with MCAT scores obtained with extra test administration time, compared with standard administration time, had no significant difference in rate of medical school admission but had lower rates of passing the USMLE Step examinations and of medical school graduation within 4 to 8 years after matriculation. These findings raise questions about the types of learning environments and support systems needed by students who test with extra time on the MCAT to enable them to succeed in medical school.

To present for black and white patients with medically uncontrolled glaucoma 10-year results of treatment with 1 of 2 randomly assigned surgical intervention sequences. Randomized clinical trial. Three hundred thirty-two black patients (451 eyes) and 249 white patients (325 eyes). Eyes had glaucoma that could not be controlled with medications alone. Eyes were randomly assigned to 1 of 2 sequences: argon laser trabeculoplasty (ALT)-trabeculectomy-trabeculectomy (ATT) or trabeculectomy-ALT-trabeculectomy (TAT). Second and third interventions were offered after failure of the preceding intervention. Minimum required intraocular pressure (IOP) for intervention failure ranged upward from 18 mmHg, the value depending on whether recent optic disc or visual field (VF) deterioration occurred, and on the magnitude of the field defect. Patients were observed every 6 months, with total potential follow-up ranging from 8 years, 4 months to 13 years. The averages over follow-up of (1) the percentage of eyes having moderate loss of VF and (2) the percentage of eyes having moderate loss of visual acuity (VA). Race-treatment interactions in VF and VA loss are significant for the 2 main outcome measures; therefore, results of treatment sequence differences are presented by race. In black patients the average percent of eyes with VF loss was less in the ATT sequence than in the TAT sequence, a difference that is not statistically significant at any visit. In white patients, conversely, after 18 months the average percent of eyes with VF loss was less in the TAT sequence, a difference that increases and is statistically significant in years 8 to 10. In both black and white patients, the average percent of eyes with VA loss was less in the ATT sequence; this difference is statistically significant throughout 10 follow-up years in black patients and is statistically significant only for the first year in white patients. In both black and white patients, average IOP reductions were greater in the TAT sequence, though the TAT-ATT difference was substantially greater in white patients. In both black and white patients, first-intervention failure rates were substantially lower for trabeculectomy than for trabeculoplasty. Ten-year cumulative incidence of unilateral VF impairment comparable to legal blindness was modest in eyes of black (ATT 11.9%, TAT 18.5%) and white (ATT 9.9%, TAT 7.3%) patients. Although IOP was lowered in both sequences in black and white patients with medically uncontrolled glaucoma, long-term visual function outcomes were better for the ATT sequence in black patients and better for the TAT sequence in white patients.

Meal patterns have received little attention in nutrition studies. The aim of this study is to present the findings on general meal patterns of Malaysian adults. The Malaysian Adults Nutrition Survey (MANS), carried out in 2002 and 2003, involved 6,928 adults selected by stratified random sampling from all households by zone in Peninsular Malaysia, Sabah and Sarawak. In general, the results showed that most respondents (74.16%) ate three meals per day; 89.20% of the respondents consumed breakfast, while 88.57% consumed lunch and 91.97% consumed dinner with no significant difference in terms of sex. In Peninsular Malaysia, the Northern Zone had the highest number of people consuming breakfast compared to other zones. Meanwhile, the population in Sarawak had the largest proportion of people consuming lunch and dinner, but the smallest proportion of people consuming breakfast. A significantly higher number of the rural population consumed breakfast and lunch than urbanites; however there was no significant difference in dinner consumption. Generally, breakfast consumption increased with age whereby significant difference existed between the 18 to 19 years age group and the age group of 30 years and older. Lunch intake among the age groups showed no significant difference. In contrast, dinner consumption was significantly lower among the 18 to 19 years age group compared to all other age groups. Comparison among the ethnic groups showed that the Indian population had the lowest percentage of having breakfast and lunch while the Orang Asli had the lowest percentage of consuming dinner. However, the Orang Asli recorded the highest percentage for taking breakfast and lunch while the Chinese had the highest percentage of taking dinner. Considering that Malaysian adults consumed their conventional breakfast, lunch and dinner, these findings indicatethat Malaysians are maintaining their traditional meal patterns.

Visual perception is the fundamental skill required for a child to recognize words, and to read and write. There was no visual perception assessment tool developed for preschool children based on Chinese characters in Taiwan. The purposes were to develop the computerized visual perception assessment tool for Chinese Characters Structures and to explore the psychometrical characteristic of assessment tool. This study adopted purposive sampling. The study evaluated 551 kindergarten-age children (293 boys, 258 girls) ranging from 46 to 81 months of age. The test instrument used in this study consisted of three subtests and 58 items, including tests of basic strokes, single-component characters, and compound characters. Based on the results of model fit analysis, the higher-order item response theory was used to estimate the performance in visual perception, basic strokes, single-component characters, and compound characters simultaneously. Analyses of variance were used to detect significant difference in age groups and gender groups. The difficulty of identifying items in a visual perception test ranged from -2 to 1. The visual perception ability of 4- to 6-year-old children ranged from -1.66 to 2.19. Gender did not have significant effects on performance. However, there were significant differences among the different age groups. The performance of 6-year-olds was better than that of 5-year-olds, which was better than that of 4-year-olds. This study obtained detailed diagnostic scores by using a higher-order item response theory model to understand the visual perception of basic strokes, single-component characters, and compound characters. Further statistical analysis showed that, for basic strokes and compound characters, girls performed better than did boys; there also were differences within each age group. For single-component characters, there was no difference in performance between boys and girls. However, again the performance of 6-year-olds was better than that of 4-year-olds, but there were no statistical differences between the performance of 5-year-olds and 6-year-olds. Results of tests with basic strokes, single-component characters and compound characters tests had good reliability and validity. Therefore, it can be apply to diagnose the problem of visual perception at preschool. Copyright © 2014 Elsevier Ltd. All rights reserved.

(1) to determine differences between minorities vs. non-minorities on demographic, injury and rehabilitation characteristics and functional outcomes at admission, discharge and 1-year post-injury and (2) to examine differences in functional outcome at 1-year post-injury among (African-Americans, Hispanics and Whites). Retrospective study. Longitudinal data were extracted from the TBI Model Systems database. 4929 individuals with moderate-to-severe TBI (3354 Whites vs. 1575 Minorities: 1207 African-Americans and 368 Hispanics) hospitalized between 1989-2004. Functional outcomes at 1-year post-injury (Disability Rating Scale, Functional Independence Measure, Glasgow Outcome Scale-Extended and Community Integration Questionnaire). At discharge and 1-year post-injury, minorities had poorer functional outcomes compared with Caucasians on all measures. After controlling for sociodemographic, injury and functional characteristics at admission, Hispanics and African-Americans still showed worse functional outcomes at 1-year post-injury compared with Whites on the DRS, FIM and CIQ. There were no significant differences between African Americans and Hispanics. Minorities had significantly reduced long-term functional outcome after rehabilitation relative to Whites. It is imperative that rehabilitation professionals' consider factors related to poorer long-term functional outcome and work to improve the quality of life of minorities with TBI.

Objectives. We estimated the effect of the ACA expansion of dependents’ coverage on health care expenditures and utilization for young adults by race/ethnicity. Methods. We used difference-in-difference models to estimate the impact of the ACA expansion on health care expenditures, out-of-pocket payments (OOP) as a share of total health care expenditure, and utilization among young adults aged 19 to 26 years by race/ethnicity (White, African American, Latino, and other racial/ethnic groups), with adults aged 27 to 30 years as the control group. Results. In 2011 and 2012, White and African American young adults aged 19 to 26 years had significantly lower total health care spending compared with the 27 to 30 years cohort. OOP, as a share of health care expenditure, remained the same after the ACA expansion for all race/ethnicity groups. Changes in utilization following the ACA expansion among all racial/ethnic groups for those aged 19 to 26 years were not significant. Conclusions. Our study showed that the impact of the ACA expansion on health care expenditures differed by race/ethnicity. PMID:25905850

This study examined and compared, based on year of study and gender, the health and performance indices of university undergraduate students. Eighty-nine students (mean±standard deviation age, 22.47±2.22 years) were randomly selected for assessment prior to second semester examination of 2015/2016 academic year. body mass index, resting metabolic rate, visceral fat, skeletal muscle mass, body fat, systolic & diastolic blood pressure, resting heart rate, upper & lower body endurance, handgrip strength, and lower back and hamstring flexibility were assessed. The students had sedentary heart rate, low skeletal muscle mass, average upper and lower body endurance, and weak handgrip strength. Significant difference existed in the visceral fat (P=0.008) between third and fourth year students. There were significant gender differences in resting metabolic rate (P=0.000), skeletal muscle mass (P=0.000), body fat (P=0.000), systolic blood pressure (P=0.001), heart rate (P=0.005) and handgrip strength (P=0.000). There are gender differences in association between health and performance indices. Dependable health education and pragmatic involvement of undergraduate university students in structured exercise programmes are recommended. PMID:29114505

The current study investigated the genetic and environmental etiology of individual differences in salivary testosterone during adolescence, using data from 49 pairs of monozygotic twins and 68 pairs of dizygotic twins, ages 14–19 years (M = 16.0 years). Analyses tested for sex differences in genetic and environmental influences on testosterone and its relation to pubertal development. Among adolescent males, individual differences in testosterone were substantially heritable (55%), and significantly associated with self-reported pubertal status (controlling for age) via common genetic influences. In contrast, there was no heritable variation in testosterone for females, and testosterone in females was not significantly associated with pubertal status after controlling for age. Rather, environmental influences shared by twins raised together accounted for all of the familial similarity in female testosterone (53%). This study adds to a small but growing body of research that investigates genetic influences on individual differences in behaviorally-relevant hormones. PMID:24523135

There are limited scientific data on the impact of smoking on patient-reported outcomes following minimally invasive spine surgery. The aim of this multicenter observational study was to examine the relationship between daily smoking and patient-reported outcome at 1 year using the Oswestry Disability Index (ODI) after microdecompression for single- and two-level central lumbar spinal stenosis (LSS). Secondary outcomes were the length of hospital stays, perioperative and postoperative complications. Data were collected through the Norwegian Registry for Spine Surgery (NORspine). A total of 825 patients were included (619 nonsmokers and 206 smokers). For the whole patient population there was a significant difference between preoperative ODI and ODI at 1 year (17.3 points, 95% CI 15.93-18.67, p < 0.001). There was a significant difference in ODI change at 1 year between nonsmokers and smokers (4.2 points, 95% CI 0.98-7.34, p = 0.010). At 1 year 69.6% of nonsmokers had achieved a minimal clinically important difference (≥10 points ODI improvement) compared to 60.8% of smokers (p = 0.008). There was no difference between nonsmokers and smokers in the overall complication rate (11.6% vs. 9.2%, p = 0.34). There was no difference between nonsmokers and smokers in length of hospital stays for either single-level (2.3 vs. 2.2 days, p = 0.99) or two-level (3.1 vs. 2.3 days, p = 0.175) microdecompression. Smoking was identified as a negative predictor for ODI change in a multiple regression analysis (p = 0.001) CONCLUSIONS: Nonsmokers experienced a significantly larger improvement at 1 year following microdecompression for LSS compared to smokers. Smokers were less likely to achieve a minimal clinically important difference. However, it should be emphasized that considerable improvement also was found among smokers.

This study investigated the participation and performance trends as well as the age and gender interaction at the Olympic distance 'Zürich Triathlon' (1.5 km swim, 40 km cycle and 10 km run) from 2000 to 2010 in 7,939 total finishers (1,666 females and 6,273 males). Female triathletes aged from 40 to 54 years significantly (P < 0.05) increased their participation while the participation of younger females and males remained stable. Males of 50-54 years of age and females of 45-49 years of age improved their total race time. For elite top five overall triathletes, mean gender differences in swimming, cycling, running and overall race time were 15.2 ± 4.6%, 13.4 ± 2.3%, 17.1 ± 2.5%, and 14.8 ± 1.8%, respectively. For both elite and age group athletes, the gender difference in cycling time was significantly (P <0.001) lower than for swimming and running. The gender difference in overall Olympic distance triathlon performance increased after the age of 35 years, which appeared earlier compared to long distance triathlon as suggested by previous studies. Future investigations should compare gender difference in performance for different endurance events across age to confirm a possible effect of exercise duration on gender difference with advancing age.

In the limited research into suicides in older adults, they have been treated as a homogenous group without distinguishing between different age groups. This study aimed to compare differences in sociodemographic variables, recent life events, and mental and physical illnesses between three age groups within older adults who died by suicide: young-old (65-74 years), middle-old (75-84 years), and oldest old (85 years and over) in Queensland, Australia, during the years 2000-2012 (N = 978). The Queensland Suicide Register was utilized for the analysis. Annual suicide rates were calculated. Odds ratios with 95% confidence intervals and χ 2 tests for trend were calculated to examine differences between the three groups. Suicide rates were increasing with age for males, but not for females. Hanging and firearms were the predominant methods of suicides. However, suffocation by plastic bag and drowning as suicide methods increased with age, in contrast firearms and explosives decreased with age. Overall, psychiatric problems, suicidal behavior, legal and financial stressors, and relationship problems decreased significantly with age, meanwhile physical conditions and bereavement increased with age. Suicide across older adulthood is not a homogenous phenomenon. Our findings showed significant differences in the prevalence of potential risk factors within the three different age groups considered. To prevent suicide in older adults would require targeting specific factors for each subgroup while using holistic and comprehensive approaches.

To compare the effect of anti-reflux surgery (ARS) versus proton pump inhibitor therapy on lower oesophageal sphincter (LOS) function and oesophageal acid exposure in patients with chronic gastro-oesophageal reflux disease (GORD) over a decade of follow-up. In this randomised, prospective, multicentre study we compared LOS pressure profiles, as well as oesophageal exposure to acid, at baseline and at 1 and 10 years after randomisation to either open ARS (n = 137) or long-term treatment with omeprazole (OME) 20-60 mg daily (n = 108). Median LOS resting pressure and abdominal length increased significantly and remained elevated in patients operated on with ARS, as opposed to those on OME. The proportion of total time (%) with oesophageal pH <4.0 decreased significantly in both the surgical and medical groups, and was significantly lower after 1 year in patients treated with ARS versus OME. After 10 years, oesophageal acid exposure was normalised in both groups, with no significant differences, and bilirubin exposure was within normal limits. After 10 years, patients with or without Barrett's oesophagus did not differ in acid reflux control between the two treatment options. Open ARS and OME were both effective in normalising acid reflux into the oesophagus even when studied over a period of 10 years. Anatomically and functionally the LOS was repaired durably by surgery, with increased resting pressure and abdominal length.

Describe the total energy value and percentage contribution of calories from macronutrients in the diet of elderly individuals living in Fortaleza/CE. This is a population-based, cross-sectional domiciliary study, which included 458 elderly individuals (66.6% women). The variables evaluated were total energy value (TEV) and the percentage contribution of calories from proteins, carbohydrates, and lipids. The results are shown as mean, standard deviation, and percentile distribution (P5, P10, P25, P50, P75, P90, P95). The Student's t-test and analysis of variance (one-way ANOVA) with LSD post-hoc tests were used to determine the statistical significance of means between two groups and among three or more groups, respectively. When comparing the mean values of TEV among categories of socioeconomic and demographic variables, statistically significant differences were found between women for ethnicity, years of schooling and socioeconomic level. Among men, differences were found for years of schooling and socioeconomic level. The mean energy value of men's diet was significantly higher than that of women (1475.8 kcal and 1236.4 kcal, respectively). The mean values of calorie percentage contribution from proteins, carbohydrates, and lipids were similar between men and women. The elderly of this study showed significant differences in mean values of TEV between sexes and between the categories years of schooling and socioeconomic level. Women also showed significant differences between the ethnic categories. The mean relative contribution of macronutrients in TEV was similar between genders and age groups.

The aims of this study are to study the surgical outcomes in patients with stress-predominant mixed urinary incontinence (MUI) treated with tension-free vaginal tape, and to evaluate the effect of concomitant anterior colpoplasty. A total of 134 women with MUI clinical and urodynamic were assessed at 6 months and annually (maximum 9 years) after surgery. As a whole, a complete healing of 49-51% at 3 years is observed, which hence could result in a tax drop of 36.8% at 5-9 years. Nevertheless, the rate of healing or improvement (subjective) is 73.7% at long term (5-9 years). There were no significant differences between the two techniques used: TVT vs TVT-Obturator. On the other hand, we have found significant differences between association of anterior colpoplasty and not (complete healing rate 34.6% vs 64.6%, p = 0.014), at 2 years of monitoring. MUI with cystocele presents better surgical results for two components of incontinence, with its physiopathogenic implications.

To evaluate the long-term outcomes of pylorus-vagus-preserving partial gastrectomy for early gastric cancer in middle third of stomach. Between January 2004 and June 2009, 46 patients with early gastric cancer in middle third of stomach underwent pylorus-vagus-preserving partial gastrectomy (PPG) while another 85 patients had conventional distal gastrectomy (DG). Clinicopathologic data and follow-up results of two groups were analyzed retrospectively, including the results of subjective nutritional assessments, laboratory blood biochemical data, endoscopic findings of remnant stomach and total 5-year survival rates. Postprandial dumping syndrome occurred in 7 patients (8.2%) in DG group while no syndrome occurred in PPG group. The incidence of gallbladder stones at 18 months after operation in DG group was higher than that in PPG group. Significant difference existed between two groups (P<0.05). Even though no significant difference existed in laboratory blood biochemical data and endoscopic findings, PPG group recovered better and regurgitation was frequently found in DG group. Food residue in gastric remnant was frequently observed in PPG (31.1%) than in DG (10.8%, P<0.05) by endoscopic findings. At 2 years post-operation, the postoperative 5-year recurrence rate was 6.5% (2/46) in PPG group versus 8.2% (7/85) in DG group. However no significant difference existed between 2 groups (P=0.724). No significant difference existed between PPG group (91.3%) and DG group (90.6%) in overall 5-year survival rate. For early gastric cancer in middle third of stomach, pylorus-vagus-preserving partial gastrectomy is effective in maintaining postoperative function. And it has the same postoperative survival rate as conventional distal gastrectomy.

To evaluate visual field progression with trend and event analysis in open angle glaucoma patients under treatment. Fifteen year follow-up results of 408 eyes of 217 glaucoma patients who were followed at Adnan Menderes University, Department of Ophthalmology between 1998 and 2013 were analyzed retrospectively. Visual field data were collected for Mean Deviation (MD), Visual Field Index (VFI), and event occurrence. There were 146 primary open-angle glaucoma (POAG), 123 pseudoexfoliative glaucoma (XFG) and 139 normal tension glaucoma (NTG) eyes. MD showed significant change in all diagnostic groups (p<0.001). The difference of VFI between first and last examinations were significantly different in POAG (p<0.001), and XFG (p<0.003) but not in NTG. VFI progression rates were -0.3, -0.43, and -0.2 % loss/year in treated POAG, XFG, and NTG, respectively. The number of empty triangles were statistically different between POAG-NTG (p=0.001), and XFG-NTG (p=0.002) groups. The number of half-filled (p=0.002), and full-filled (p=0.010) triangles were significantly different between XFG-NTG groups. Functional long-term follow-up of glaucoma patients can be monitored with visual field indices. We herein report our fifteen year follow-up results in open angle glaucoma.

Insight is increasingly seen as an important variable for study in psychotic illness, particularly in relation to treatment adherence. This study aims to quantify the association of insight with outcome, sociodemographic variables and diagnosis in a large stable patient sample. Data are from a one-year, open-label, international, multicenter trial (n=670) of long-acting risperidone in adult symptomatically stable patients with schizophrenia or schizoaffective disorder. Psychopathology and insight were quantified using the Positive and Negative Syndrome Scale (PANSS). Patients were assessed at four time points over the year of the study. 31.2% of the sample showed clinically significant deficits in insight at baseline. There were no differences based on sex, but significant differences in age and diagnosis, with oldest patients and schizophrenia patients (cf., schizoaffective disorder) showing more deficits. Baseline insight impairment was correlated with change in PANSS score at one year (r=-0.243, p<0.001). Recursive partitioning showed that, of those whose symptoms improved, those whose insight also improved were more likely to complete the trial. Insight is important above and beyond the effects of symptoms for predicting continuation in drug trials. This may have implications for the design and analysis of such trials, as well as suggesting the importance of targeting insight in treatment to increase likelihood of adherence to treatment. There also appear to be small but significant differences in insight based on age and diagnosis within the schizophrenia spectrum.

Yield and nutrient acquisition advantages are frequently found in intercropping systems. However, there are few published reports on soil fertility in intercropping relative to monocultures. A field experiment was therefore established in 2009 in Gansu province, northwest China. The treatments comprised maize/faba bean, maize/soybean, maize/chickpea and maize/turnip intercropping, and their correspoding monocropping. In 2011 (the 3rd year) and 2012 (the 4th year) the yields and some soil chemical properties and enzyme activities were examined after all crop species were harvested or at later growth stages. Both grain yields and nutrient acquisition were significantly greater in all four intercropping systems than corresponding monocropping over two years. Generally, soil organic matter (OM) did not differ significantly from monocropping but did increase in maize/chickpea in 2012 and maize/turnip in both years. Soil total N (TN) did not differ between intercropping and monocropping in either year with the sole exception of maize/faba bean intercropping receiving 80 kg P ha−1 in 2011. Intercropping significantly reduced soil Olsen-P only in 2012, soil exchangeable K in both years, soil cation exchangeable capacity (CEC) in 2012, and soil pH in 2012. In the majority of cases soil enzyme activities did not differ across all the cropping systems at different P application rates compared to monocrops, with the exception of soil acid phosphatase activity which was higher in maize/legume intercropping than in the corresponding monocrops at 40 kg ha−1 P in 2011. P fertilization can alleviate the decline in soil Olsen-P and in soil CEC to some extent. In summary, intercropping enhanced productivity and maintained the majority of soil fertility properties for at least three to four years, especially at suitable P application rates. The results indicate that maize-based intercropping may be an efficient cropping system for sustainable agriculture with carefully managed fertilizer inputs. PMID:25486249

In order to apply the right treatment for hemostatic disorders in pediatric patients, laboratory data should be interpreted with age-appropriate reference ranges. The purpose of this study was to determining age-dependent reference range values for prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen tests, and D-dimer tests. A total of 320 volunteers were included in the study with the following ages: 1 month - 1 year (n = 52), 2 - 5 years (n = 50), 6 - 10 years (n = 48), 11 - 17 years (n = 38), and 18 - 65 years (n = 132). Each volunteer completed a survey to exclude hemostatic system disorder. Using a nonparametric method, the lower and upper limits, including 95% distribution and 90% confidence intervals, were calculated. No statistically significant differences were found between PT and aPTT values in the groups consisting of children. Thus, the reference ranges were separated into child and adult age groups. PT and aPTT values were significantly higher in the children than in the adults. Fibrinogen values in the 6 - 10 age group and the adult age group were significantly higher than in the other groups. D-dimer levels were significantly lower in those aged 2 - 17; thus, a separate reference range was established. These results support other findings related to developmental hemostasis, confirming that adult and pediatric age groups should be evaluated using different reference ranges.

To determine whether nucleos(t)ide reverse transcriptase inhibitors (NRTI) contribute to an accelerated loss in telomere length (TL) in HIV-infected patients on antiretroviral therapy (ART). Substudy of randomised controlled trial. Patients with HIV RNA <50 copies/mL on combination ART (n = 256) were randomised to darunavir/ritonavir (DRV/r) 800/100 mg once daily, either as monotherapy (n = 127) or with 2 NRTIs (n = 129) for up to 144 weeks. TL and telomerase activity was quantified on stored peripheral blood mononuclear cells (PBMC; n = 124) using quantitative real time PCR. Patients in the sub-study had a mean age of 44 years and had received NRTI for a mean of 6.4 years (range 1-20 years). As expected, older patients have significantly shorter TL (p = 0.006), while women had significantly longer TL (p = 0.026). There was no significant association between TL and either the duration of prior NRTI treatment (p = 0.894) or the use of a PI versus NNRTI (p = 0.107). There was no significant difference between patients who continued or ceased NRTI in the mean change/year of TL or telomerase (p = 0.580 and 0.280 respectively). Continuation versus cessation of NRTI treatment was not associated with an accelerated loss in TL or telomerase activity.

Haemoglobinopathies, inherited disorders of haemoglobin synthesis (thalassaemia) or structure (sickle cell disease), are responsible for significant morbidity and mortality throughout the world. The WHO estimates that, globally, 5% of adults are carriers of a haemoglobin condition, 2.9% are carriers of thalassaemia and 2.3% are carriers of sickle cell disease. Carriers are found worldwide as a result of migration of various ethnic groups to different regions of the world. Zinc is an easily available supplement and intervention programs have been carried out to prevent deficiency in people with thalassaemia or sickle cell anaemia. It is important to evaluate the role of zinc supplementation in the treatment of thalassaemia and sickle cell anaemia to reduce deaths due to complications. To assess the effect of zinc supplementation in the treatment of thalassaemia and sickle cell disease. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Haemoglobinopathies Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of most recent search: 01 February 2013. Randomised, placebo-controlled trials of zinc supplements for treating thalassaemia or sickle cell disease administered at least once a week for at least a month. Two review authors assessed the eligibility and risk of bias of the included trials, extracted and analysed data and wrote the review. We summarised results using risk ratios or rate ratios for dichotomous data and mean differences for continuous data. We combined trial results where appropriate. We identified nine trials for inclusion with all nine contributing outcome data. Two trials reported on people with thalassaemia (n = 152) and seven on sickle cell anaemia (n = 307).In people with thalassaemia, in one trial, the serum zinc level value showed no difference between the zinc supplemented group and the control group, mean difference 47.40 (95% confidence interval -12.95 to 107.99). Regarding anthropometry, in one trial, height velocity was significantly increased in patients who received zinc supplementation for one to seven years duration, mean difference 3.37 (95% confidence interval 2.36 to 4.38) (total number of participants = 26). In one trial, however, there was no difference in body mass index between treatment groups.Zinc acetate supplementation for three months (in one trial) and one year (in two trials) (total number of participants = 71) was noted to increase the serum zinc level significantly in patients with sickle cell anaemia, mean difference 14.90 (95% confidence interval 6.94 to 22.86) and 20.25 (95% confidence interval 11.73 to 28.77) respectively. There was no significant difference in haemoglobin level between intervention and control groups, at either three months (one trial) or one year (one trial), mean difference 0.06 (95% confidence interval -0.84 to 0.96) and mean difference -0.07 (95% confidence interval -1.40 to 1.26) respectively. Regarding anthropometry, one trial showed no significant changes in body mass index or weight after one year of zinc acetate supplementation. In patients with sickle cell disease, the total number of sickle cell crises at one year were significantly decreased in the zinc sulphate supplemented group as compared to controls, mean difference -2.83 (95% confidence interval -3.51 to -2.15) (total participants 130), but not in zinc acetate group, mean difference 1.54 (95% confidence interval -2.01 to 5.09) (total participants 22). In one trial at three months and another at one year, the total number of clinical infections were significantly decreased in the zinc supplemented group as compared to controls, mean difference 0.05 (95% confidence interval 0.01 - 0.43) (total number of participants = 36), and mean difference -7.64 (95% confidence interval -10.89 to -4.39) (total number of participants = 21) respectively. According to the results, there is no evidence from randomised controlled trials to indicate any benefit of zinc supplementation with regards to serum zinc level in patients with thalassaemia. However, height velocity was noted to increase among those who received this intervention.There is mixed evidence on the benefit of using zinc supplementation in people with sickle cell disease. For instance, there is evidence that zinc supplementation for one year increased the serum zinc levels in patients with sickle cell disease. However, though serum zinc level was raised in patients receiving zinc supplementation, haemoglobin level and anthropometry measurements were not significantly different between groups. Evidence of benefit is seen with the reduction in the number of sickle cell crises among sickle cell patients who received one year of zinc sulphate supplementation and with the reduction in the total number of clinical infections among sickle cell patients who received zinc supplementation for both three months and for one year.The conclusion is based on the data from a small group of trials,which were generally of good quality, with a low risk of bias. The authors recommend that more trials on zinc supplementation in thalassaemia and sickle cell disease be conducted given that the literature has shown the benefits of zinc in these types of diseases.

Post-traumatic brain injury fatigue (PTBIF) is a major problem in the years after traumatic brain injury (TBI), yet little is known about its persistence and resolution. The objective of the study was to identify factors related to PTBIF remission and resolution. TBI Model System registrants at five centres participated in interviews at either one and two years post-injury (Y1-2 Cohort), or two and five years post-injury (Y2-5 Cohort). Characteristics of participants with PTBIF remission were compared to those with PTBIF persistence. Variables studied included the presence of and changes in disability, sleep dysfunction, mood, and community participation. The Functional Independence Measure did not differ significantly between groups or over time. In the Y1-2 Cohort the Fatigue Resolved group scored significantly better on the Disability Rating Scale and Pittsburgh Sleep Quality Index. In the Y2-5 Cohort the Fatigue Resolved group scored significantly higher on a measure of community participation. It was concluded that fewer than half of the sample in each cohort experienced a remission of PTBIF between time points. Persistence of PTBIF 1-2 years post-injury is associated with disability, sleep disturbance, and depression while persistence of fatigue beyond 2 years post-injury appears to be related to participation level, underscoring the potential impact of effective surveillance, assessment, and treatment of this condition in optimising life after TBI. Differences in fatigue progression may point to the presence of different types of PTBIF.

This randomized, controlled trial evaluated the clinical efficacy of Billroth I (BI) and Roux-en-Y (RY) reconstruction at 1 year after distal gastrectomy for gastric cancer. The primary end point was the amount of body weight lost at 1 postoperative year, and secondary end points included other items related to nutritional status such as serum albumin and lymphocyte count, as well as endoscopic examination findings of the remnant stomach and esophagus. Of the 332 patients enrolled, 163 were assigned to the BI group and 169 were randomized to the RY group. The loss in body weight 1 year after surgery did not differ significantly between the BI and RY groups (9.1 % and 9.7 %, respectively, p = 0.39). There were no significant differences in other aspects of nutritional status between the 2 groups. Endoscopic examination 1 year after gastrectomy showed reflux esophagitis in 26 patients (17 %) in the BI group versus 10 patients (6 %) in the RY group (p = 0.0037), while remnant gastritis was observed in 71 patients (46 %) in the BI group versus 44 patients (28 %) in the RY group (p = 0.0013); differences were significant for both conditions. Multivariable analysis showed that the only reconstruction was the independently associated factor with the incidence of reflux esophagitis. RY reconstruction was not superior to BI in terms of body weight change or other aspects of nutritional status at 1 year after surgery, although RY more effectively prevented reflux esophagitis and remnant gastritis after distal gastrectomy.

Measures of medication adherence have become common parameters with which disease management (DM) programs are being evaluated, leading to the question of how this concept should be measured in the particular context of a DM intervention. We hypothesize that DM improves adherence to prescriptions more than the rate with which prescriptions are being filled. We used health plan claims data to construct 13 common measures of medication adherence for five chronic conditions. The measures were operationalized in three different ways: the Prescription Fill Rate (PFR), which requires only one prescription; the Medication Possession Ratio (MPR), which requires a supply that covers at least 80% of the year; and the Length of Gap (LOG), which requires no gap greater than 30 days between prescriptions. We compared results from a baseline year to results during the first year of a DM program. Changes in adherence were quite small in the first year of the intervention, with no changes greater than six percentage points. In the intervention year, three measures showed a significant increase based on all three operational definitions, but two measures paradoxically decreased based on the PFR. For both, the MPR and the LOG suggested either no change or significant improvement. None of the MPR and LOG measures pointed toward significantly lower compliance in the intervention year. Different ways to operationalize the concept of medication adherence can lead to fundamentally different conclusions. While more complex, MPR- and LOG-based measures could be more appropriate for DM evaluation. Our initial results, however, need to be confirmed by data covering longer term follow-up.

The aim of this study was to evaluate changes in foot shape of women 5 years after undergoing breast amputation. Evaluation of foot shape was performed using a non-invasive device for computer analysis of the plantar surface of the foot. Obtained results were compared between feet on the healthy breast side (F1) and on the amputated breast side (F2). 128 women aged 63.60 ± 8.83, 5-6 years after breast amputation were enrolled in this case-control study. Weight bearing on the lower extremity on the amputated breast side (F1) compared with the healthy breast side (F2) showed statistically significant differences (p < 0.01). Patients put more weight onto the healthy breast side. No statistically significant difference was found with regard to F1 and F2 foot length (p = 0.4239), as well as BETA (p = 0.4470) and GAMMA (p = 0.4566) angles. Highly statistically significant differences were noted with respect to foot width, ALPHA angle, and Sztriter-Godunov index-higher values were observed on the healthy breast side (p < 0.001). Highly statistically significant differences were also noted while comparing Clark's angles, higher values being observed on the operated breast side (p < 0.001). Differences in foot shape on the healthy breast side and amputated breast side constitute a long-term negative consequence of mastectomy, and can be caused by unbalanced weight put on feet on the healthy breast side compared to the amputated breast side.

A retrospective study. To elucidate sex-related differences in the age at synchondroses closure, the normative size of the atlas, and the ossification patterns of the atlas in Japanese children. The atlas develops from three ossification centers during childhood. The anterior and posterior synchondroses, which are separate ossification centers, mimic fracture lines on computed tomography (CT). Sex-related differences of age dependent morphological changes of the atlas in a large sample size have not been reported. This study analyzed data of 688 subjects (449 boys) between 0 and 18 years old who underwent CT examination of the head and/or neck between January 2010 and July 2016. The age at synchondroses closure, anteroposterior outer, inner, and spinal canal widths of the atlas, and variations of the ossification centers were examined. Anterior synchondroses closed by 10 years in boys and by 7 years in girls. Significant earlier closure of anterior synchondroses was observed in girls than in boys (P < 0.05 at 4 and 5 years old). Posterior synchondrosis closed by 6 years in boys and by 5 years in girls. The outer, inner, and spinal canal widths increased up to 10 to 15 years in both sexes, although all three parameters in girls peaked 3 years earlier than those in boys. All parameters in boys were significantly larger than those in girls, except in the 10- to 12-year-old age category. Two or more ossification centers in the anterior arch were observed in 18.3% subjects, and 6% had midline ossification centers in the posterior arch of the atlas. Distinct sex-related differences in the age at anterior synchondroses closure and the size of the atlas were observed in Japanese children. Knowledge of morphological features of the atlas could help distinguish fractures from synchondroses. 3.

The study is going to investigate the fundamental frequency (F(0)) and perturbation measures of sustained vowels in 360 native Malaysian Malay children aged between 7 and 12 years using acoustical analysis. Praat software (Boersma and Weenink, University of Amsterdam, The Netherlands) was used to analyze the F(0) and perturbation measures of the sustained vowels. Statistical analyses were conducted to determine the significant differences in F(0) and perturbation measures across the vowels, sex, and age groups. The mean F(0) of Malaysian Malay male and female children were reported at 240±34.88 and 254.48±23.35Hz, respectively. The jitter (Jitt), relative average perturbation (RAP), five-point period perturbation quotient (PPQ5), shimmer (Shim), and 11-point amplitude perturbation quotient (APQ11) of Malaysian male children were reported at 0.43±0.26%, 0.25±0.16%, 0.26±0.15%, 2.48±1.61%, and 1.75±1.04%, respectively. As for female children, the Jitt, RAP, PPQ5, Shim, and APQ11 were reported at 0.42±0.22%, 0.25±0.14%, 0.25±0.13%, 2.47±1.53%, and 1.75±1.10%, respectively. No significant differences in F(0) were reported across the Malay vowels for both males and females. Malay females had significantly higher F(0) than that in Malay males at the age of 8, 10, and 12 years. Malaysian Malay children underwent the nonsystematic decrement in F(0) across the age groups. Significant differences in F(0) were found across the age groups. Significant differences in perturbation measures were observed across the vowels in certain age groups of Malay males and females. Generally, no significant differences in perturbation measures between the sex were observed in all the age groups and vowels. No significant differences in all the perturbation measures across the age groups were reported in both Malaysian Malay male and female children. Copyright © 2012 The Voice Foundation.

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

Although cross-sectional studies have shown a positive association between Se and cholesterol concentrations, a recent randomised controlled trial in 501 elderly UK individuals of relatively low-Se status found that Se supplementation for 6 months lowered total plasma cholesterol. The Danish PRECISE (PREvention of Cancer by Intervention with Selenium) pilot study (ClinicalTrials.gov ID: NCT01819649) was a 5-year randomised, double-blinded, placebo-controlled trial with four groups (allocation ratio 1:1:1:1). Men and women aged 60-74 years (n 491) were randomised to 100 (n 124), 200 (n 122) or 300 (n 119) μg Se-enriched yeast or matching placebo-yeast tablets (n 126) daily for 5 years. A total of 468 participants continued the study for 6 months and 361 participants, equally distributed across treatment groups, continued for 5 years. Plasma samples were analysed for total and HDL-cholesterol and for total Se concentrations at baseline, 6 months and 5 years. The effect of different doses of Se supplementation on plasma lipid and Se concentrations was estimated by using linear mixed models. Plasma Se concentration increased significantly and dose-dependently in the intervention groups after 6 months and 5 years. Total cholesterol decreased significantly both in the intervention groups and in the placebo group after 6 months and 5 years, with small and nonsignificant differences in changes in plasma concentration of total cholesterol, HDL-cholesterol, non-HDL-cholesterol and total:HDL-cholesterol ratio between intervention and placebo groups. The effect of long-term supplementation with Se on plasma cholesterol concentrations or its sub-fractions did not differ significantly from placebo in this elderly population.

The aim of this study was to determine the impact of hypovitaminosis D on Gastric Bypass outcomes. We retrospectively reviewed all patients who underwent primary intention Gastric Bypass in our center between January 2012 and December 2013. Postoperative complications, 1 and 2-year excess weight loss were compared between patients with and without hypovitaminosis D. Among 258 patients who met inclusion criteria, 56 (21.7%) presented with vitamin D deficiency. Mean age was 41.73 ± 12.95 years. Mean BMI was 40.90 kg/m 2 (34-58 kg/m 2 ). No statistically significant difference in postoperative complication rate was found between patients with and without hypovitaminosis D. Mean 1-year excess weight loss was 75.24%. In patients with vitamin D deficiency mean 1-year excess weight loss was 71.90 versus 76.15% in patients with optimal serum vitamin D level (p = 0.17). No significant difference was found after a 2-year follow-up. In patients presenting with vitamin D insufficiency, 1-year excess weight loss was 75.64 versus 79.34% in patients with optimal serum vitamin D level (p = 0.53). After a 2-year follow-up, there was a significant difference between patients presenting with and without vitamin D insufficiency (79.45 versus 91.71%; p = 0.01) and between patients presenting with and without hypovitaminosis D (80.50 versus 91.71%; p = 0.01). In our study, hypovitaminosis D seemed to have a negative impact on long term excess weight loss, but not on short-term outcome or postoperative complications. The role of systematic supplementation before bariatric surgery has to be explored in prospective studies.

OBJECTIVE: The objective of this study is to explore the student's perspectives toward the interactive lectures as a teaching and learning method in an integrated curriculum. MATERIALS AND METHODS: This cross-sectional study was conducted among 1st, 2nd and 3rd year male medical students (n = 121). A self-administered questionnaire based on the Visual, Auditory, Reader, Kinesthetic learning styles, learning theories, and role of feedback in teaching and learning on five-point Likert rating scale was used. The questionnaire was constructed after extensive literature review. RESULTS: There was an 80% response rate in this study. The total number of undergraduate medical students responded in the study were n = 97, 34 students of 1st year, n = 30 students of 2nd year and n = 33 student were in 3rd year, the mean scores of the student responses were calculated using Independent samples Kruskal–Wallis. There was no significant difference in the responses of the students of different years except for the question “The Interactive lectures facilitate effective use of learning resources.” Which showed significant difference in the responses of the 3 years students by Independent samples Kruskal–Wallis test. No significant association was found between the year of study and items of the questionnaire except for the same item, “ The Interactive lectures facilitates effective use of learning resources” by Spearman rank correlation test. CONCLUSION: The students perceive interactive lecture as an effective tool for facilitating visual and auditory learning modes, and for achieving curricular strategies. The student find the feedback given during the interactive lectures is effective in modifying learning attitude and enhancing motivation toward learning. PMID:29296601

The purpose of this study was to investigate the duration required by children with cochlear implants to approximate the norms of voice acoustic parameters. The study design is retrospective. Thirty children with cochlear implants (chronological ages ranging between 4.1 and 6.7 years) were divided into three groups, based on the postimplantation duration. Ten normal-hearing children (chronological ages ranging between 4 and 7 years) were selected as the control group. All implanted children underwent an objective voice analysis using Dr. Speech software (Tiger DRS, Inc., Seattle, WA, USA) at 6 months and at 1 and 2 years of implant use. Voice analysis was done for the children in the control group and means were derived for all the parameters analyzed to obtain the normal values. Habitual fundamental frequency (HFF), jitter (frequency variation), and shimmer (amplitude variation) were the voice acoustic parameters analyzed for the vowels |a|, |i|, and |u|. The obtained values of these parameters were then compared with the norms. HFF for the children with implant use for 6 months and 1 year did significantly differ from the control group. However, there was no significant difference (P > 0.5) observed in the children with implant use for 2 years, thus matching the norms. Jitter and shimmer showed a significant difference (P < 0.5) even at 2 years of implant use when compared with the control group. The findings of the study divulge that children with cochlear implants approximate age-matched normal-hearing kids with respect to the voice acoustic parameter of HFF by 2 years of implant use. However, jitter and shimmer were not found to stabilize for the duration studied. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

This controlled prospective split-mouth study evaluated the clinical behavior of two different resin composites in extended Class II cavities over a period of four years. Thirty patients received 68 direct resin composite restorations (Grandio bonded with Solobond M: n=36, Tetric Ceram bonded with Syntac: n=32) by one dentist in a private practice. All restorations were replacement fillings, 24 cavities (35%) revealed no enamel at the bottom of the proximal box, in 33 cavities (48%) the proximal enamel width was less than 0.5mm. The restorations were examined according to modified USPHS criteria at baseline, and after six months, one, two, and four years. At each recall, impressions were taken for replica preparation. Replicas of 44 select subjects were assessed for marginal quality under a stereo light microscope (SLM) at 130x and 22 replicas were assessed under a scanning electron microscope (SEM) at 200x. Both recall rate and survival rate were 100% after four years of clinical service. No significant difference was found between the restorative materials (p>0.05; Mann-Whitney U-test). Hypersensitivities were significantly reduced over time (p<0.05; Friedman test). A significant deterioration over time was found for the criteria marginal integrity (66% bravo after four years), tooth integrity (15% bravo), filling integrity (73% bravo) and proximal contact (p<0.05; Friedman test). SLM and SEM analysis of restoration margins revealed differences in the amount of perfect margins, in favor of Tetric Ceram (p<0.05). Both materials performed satisfactorily over the four-year observation period. Due to the extension of the restorations, wear was clearly visible after four years of clinical service with 50% bravo ratings.

Sleep disturbances are common among older people (>65 years). Further, long-term use of sedative hypnoticsin older people is associated with morbidity and mortality. However, older people represent a large span of life years, and few studies have included the oldest-old above 85 years. To investigate and compare sleep quality, use of hypnotics and sleeping habits in different age groups of the older population in the Scania region, Sweden and in relation to sociodemographic- and functional status. A cross-sectional population-based study including 2931 people aged 60-93 years from five different municipalities in Scania was performed during 2001-2004. The sample was divided into age groups, young old (60-72 years), old-old (78-84 years) and oldest-old (87-93) years. Data constitutes of sleep related questions, sociodemographic- and functional status from the study 'Good Ageing in Skane'. Descriptive statistics were used to describe sleep quality, hypnotics use and sleeping habitsin relation to sociodemographic- and functional status. The aim was to investigate associations, not the magnitude of associations between variables. In all age groups, those who used hypnotics and were living alone had significantly poorer sleep quality and shortest sleeping time than nonhypnotic users and those who lived together. A significant increase of hypnotics and frequency of use was seen with increasing age. Frequency of napping increased significantly with degree of dependence in all age groups and with increasing age. Insomnia is still a problem and hypnotic use has not improved sleep for a large number of older people. Hypnotics are effective as short-term treatment, however, nonpharmacological interventions and psychological and behavioural therapies should be considered for treating older people with chronic insomnia.

The purpose of this study was to examine maturity-related differences in anthropometry and body composition in Japanese youth within a single year. Two hundred and ten Japanese youth aged from 13 to 13.99 years participated in this study. Their maturity status was assessed using a self-assessment of stage of pubic hair development. Bioelectrical impedance analysis was used to estimate percent body fat and lean body mass (LBM). Muscle thickness of the anterior thigh, posterior lower leg and rectus abdominis muscles were measured by ultrasound. For boys, height, body weight, and LBM in less mature groups were lower than that in more mature groups. The maturity-related differences were still significant after adjusting for chronological age. On the other hand, muscle thickness values in the lower extremity and abdomen differed among the groups at different stages of pubic hair development, whereas there was no maturity-related difference in the relative values corrected by LBM, except for those thickness values measured at the abdomen. For girls, only the muscle thickness at the anterior thigh and muscle thickness relative to LBM1/3 at the posterior lower leg was significantly affected by maturity status, but significant maturity-related difference was not found after adjusting for chronological age. At least for Japanese boys and girls aged 13 years, maturity status affected body size in boys, but not in girls, and the influence of maturation on the muscularity of the lower extremity and trunk muscles is less in both sexes.

A comparative study. The aims of this study were to: (1) evaluate Scoliosis Research Society (SRS)-22 questionnaire performance in normal adolescents without scoliosis to establish a normative baseline useful for evaluating the discriminate validity of the SRS-22 in primary adolescent scoliosis; and (2) investigate impact of age and sex on SRS-22 in an adolescent population unaffected by scoliosis. The SRS-22 questionnaire is widely used to measure health-related quality of life of patients with spinal disease including scoliosis and lumbar spondylolisthesis. However, normal data, which are very important, when comparing patients and nonpatients, are few, little, and there are few studies about factors that may affect SRS questionnaire performance. The adolescent population was from 14 schools located in 7 provinces. A total of 2008 adolescents (961 females, 1026 males, 21 unknown; mean age, 14.3 yr; range, 11-20) completed the simplified Chinese version of SRS-22 questionnaire and demographic questions. Surveys were stratified into 8 age-sex groups for analysis: male/female; 12 to 13.4, 13.5 to 14.9, 15 to 15.9, and more than 16 years of age. Post hoc testing and the Tukey least significant difference were used to compare differences between any 2 of the 4 age groups. Self-image scores in males were higher than those in females (P < 0.01). Pain domain scores were significantly higher in males than those in females in the 13.5- to 14.9-year-old subgroup, whereas other subgroups showed no obvious differences. The function domain scores in males who were aged 15 to 15.9 years and those older than 16 years were significantly higher than those in females (P < 0.001). There were no statistically significant differences in mental health domain scores among age-sex subgroups, with the exception of the 13.5- to 14.9-year-old group. This is the first study to characterize the sex and age influence on the SRS-22 scores in normal population. Age and sex have an important effect on SRS-22 scores, so when using the instrument to assess health-related quality of life of patients with scoliosis or other spinal disease, we should consider the differences in patients with different age and sex. 3.

The long-term effect of repetitive trauma by military parachuting on the lumbar spine is not well investigated. Therefore, the purpose of this study was to examine the development of lumbar degenerative changes during a 30-year follow-up in Japanese Ground Self Defense Forces (JGSDF) parachute infantry soldiers with normal lumbar radiographs at entry by comparison with those with non-parachute infantry soldiers. 79 non-parachutists and 65 parachutists were included for radiological examination and questionnaires for low back pain (LBP). All subjects were non-commissioned officers with similar socioeconomic status and life styles. The number of parachuting descent during the 30-year in the parachute group ranged from 208 to 630, with an average of 322. The mean age of the subjects was 18.3±0.5 years at entry and 48.5±0.3 years at follow-up. LBP had been experienced by 37% in the non-parachute group and 25% in the parachute group with no significant difference. The nature of their LBP was judged as mild. The prevalence rate of degenerative changes was similar in both groups. Disc space narrowing was detected 37 subjects (47%) in non-parachute group an 23 subjects (35%) in parachute group without significant difference. Vertebral osteophytes were detected in 52 subjects (67%) in non-parachute group and 47 subjects (72%) in parachute group without significant difference. This study did not identify any significant differences in the development of lumbar degenerative changes between the parachutists and non-parachutists over a 30-year follow-up, suggesting that military parachuting itself does not accelerate the development of intervertebral disc degeneration. Further studies are needed using large cohorts assessed by MRI as well as plain X-ray. Published by the BMJ Publishing Group Limited.

Ulnar collateral ligament (UCL) reconstructions are relatively common among professional pitchers in Major League Baseball (MLB). To the authors' knowledge, there has not been a study specifically analyzing pitching velocity after UCL surgery. These measurements were examined in a cohort of MLB pitchers before and after UCL reconstruction. There is no significant loss in pitch velocity after UCL reconstruction in MLB pitchers. Cohort study; Level of evidence, 3. Between the years 2008 to 2010, a total of 41 MLB pitchers were identified as players who underwent UCL reconstruction. Inclusion criteria for this study consisted of a minimum of 1 year of preinjury and 2 years of postinjury pitch velocity data. After implementing exclusion criteria, performance data were analyzed from 28 of the 41 pitchers over a minimum of 4 MLB seasons for each player. A pair-matched control group of pitchers who did not have a known UCL injury were analyzed for comparison. Of the initial 41 players, 3 were excluded for revision UCL reconstruction. Eight of the 38 players who underwent primary UCL reconstruction did not return to pitching at the major league level, and 2 players who met the exclusion criteria were omitted, leaving data on 28 players available for final velocity analysis. The mean percentage change in the velocity of pitches thrown by players who underwent UCL reconstruction was not significantly different compared with that of players in the control group. The mean innings pitched was statistically different only for the year of injury and the first postinjury year. There were also no statistically significant differences between the 2 groups with regard to commonly used statistical performance measurements, including earned run average, batting average against, walks per 9 innings, strikeouts per 9 innings, and walks plus hits per inning pitched. There were no significant differences in pitch velocity and common performance measurements between players who returned to MLB after UCL reconstruction and pair-matched controls.

We investigated the incidence of associated bladder tumor and prognosis in 101 cases with a pathological diagnosis of transitional cell carcinoma, selected from those with renal pelvic and ureteral tumor whom we had encountered over the 18 years between April 1976 and March 1993. Among these 101 cases, the incidence of associated bladder tumor was noted in 42 (41.6%), 23 (22.8%) with coexistence and 19 (18.8%) with subsequence. As for the primary site of renal pelvis and ureter, the coexistence was 15.4% and subsequence 20.5% in renal pelvis, and the coexistence was 24.6% and subsequence 19.3% in ureter, and the coexistence was 60.0% and subsequence 0.0% in both renal pelvis and ureter. The incidence of coexistent bladder tumor was high in both renal pelvis and ureter, but no significant difference was noted. As for the stage, the incidence of coexistence was high in T1, while subsequence was high in T2, but no significant difference was noted. As for the grade, the incidence of coexistence was high in G2, but no significant difference was noted. The 5 year survival rate was 58.2% in those without, 54.2% with coexistence, and 82.5% with subsequent bladder tumor, with a significant difference (p < 0.05) between the last two groups. The interval of subsequent bladder tumor ranged from 4 to 164 months (mean 27.7 months), with the incidence within 2 years being approximately 70.0%. It was found that the renal pelvic and ureteral tumors are frequently associated bladder tumor while associated bladder tumor dose not appear to have an ill effect on the prognosis. Therefore it is necessary that patients with renal pelvic and ureteral tumor be observed closely for 5 years, especially for the initial 2 years.

The purpose of the study was to explore Emirati teachers' perceptions of voice handicap and to analyze their acoustic characteristics to determine whether acoustic measures of teachers' voice would verify their perceptions of voice handicap. Sixty-six Emirati school teachers (33 men and 33 women), with different years of teaching experience and age, and 100 control participants (50 men and 50 women) underwent vocal assessment that included the Voice Handicap Index (VHI-Arab) and acoustic measures (F0, jitter%, shimmer%, signal to noise ratio [SNR]). Significant differences between the teachers' group scores and the control group scores on the following subscales of VHI-Arab: physical (P = 0.006), emotional (P = 0.004), and total score of the test (P = 0.002). No significant differences were found among teachers in the three VHI subscales, and the total score regarding gender (functional P = 0.307; physical P = 0.341; emotional P = 0.126; and total P = 0.184), age (functional P = 0.972; physical P = 0.525; emotional P = 0.772; and total P = 0.848), and years of teaching experience (functional P = 0.319; physical P = 0.619; emotional P = 0.926; and total P = 0.638). The significant differences between the teacher's group and the control group in three acoustic measures: F0 (P = 0.000), shimmer% (P = 0.000), and SNR (P = 0.000) were further investigated. Significant differences were found among female and male teachers in F0 (P = 0.00) and SNR (P = 0.007). As for teachers' age, significant differences were found in SNR (P = 0.028). Teachers' years of experience did not show significant differences in any of the acoustic measures. Teachers have a higher perception of voice handicap. However, they were able to produce better voice quality than control participants were, as expressed in better SNRs. This might have been caused either by manipulation of vocal properties or abusive overloading the vocal system to produce a procedurally acceptable voice quality.

To measure and compare hand function for children with normal hand development, congenital hand differences (CHD), and neuromuscular disease (NMD) using a function test with touch screen technology designed as an iPhone application. We measured touch screen hand function in 201 children including 113 with normal hand formation, 43 with CHD, and 45 with NMD. The touch screen test was developed on the iOS platform using an Apple iPhone 4. We measured 4 tasks: touching dots on a 3 × 4 grid, dragging shapes, use of the touch screen camera, and typing a line of text. The test takes 60 to 120 seconds and includes a pretest to familiarize the subject with the format. Each task is timed independently and the overall time is recorded. Children with normal hand development took less time to complete all 4 subtests with increasing age. When comparing children with normal hand development with those with CHD or NMD, in children aged less than 5 years we saw minimal differences; those aged 5 to 6 years with CHD took significantly longer total time; those aged 7 to 8 years with NMD took significantly longer total time; those aged 9 to 11 years with CHD took significantly longer total time; and those aged 12 years and older with NMD took significantly longer total time. Touch screen technology has becoming increasingly relevant to hand function in modern society. This study provides standardized age norms and shows that our test discriminates between normal hand development and that in children with CHD or NMD. Diagnostic III.

Objective Working through a depressive illness can improve mental health but also carries risks and costs from reduced concentration, fatigue, and poor on-the-job performance. However, evidence-based recommendations for managing work attendance decisions, which benefit individuals and employers, are lacking. Therefore, this study has compared the costs and health outcomes of short-term absenteeism versus working while ill (“presenteeism”) amongst employed Australians reporting lifetime major depression. Methods Cohort simulation using state-transition Markov models simulated movement of a hypothetical cohort of workers, reporting lifetime major depression, between health states over one- and five-years according to probabilities derived from a quality epidemiological data source and existing clinical literature. Model outcomes were health service and employment-related costs, and quality-adjusted-life-years (QALYs), captured for absenteeism relative to presenteeism, and stratified by occupation (blue versus white-collar). Results Per employee with depression, absenteeism produced higher mean costs than presenteeism over one- and five-years ($42,573/5-years for absenteeism, $37,791/5-years for presenteeism). However, overlapping confidence intervals rendered differences non-significant. Employment-related costs (lost productive time, job turnover), and antidepressant medication and service use costs of absenteeism and presenteeism were significantly higher for white-collar workers. Health outcomes differed for absenteeism versus presenteeism amongst white-collar workers only. Conclusions Costs and health outcomes for absenteeism and presenteeism were not significantly different; service use costs excepted. Significant variation by occupation type was identified. These findings provide the first occupation-specific cost evidence which can be used by clinicians, employees, and employers to review their management of depression-related work attendance, and may suggest encouraging employees to continue working is warranted.

Knowledge of the effects of healthy aging on brain structures is necessary to identify abnormal changes due to diseases. Many studies have demonstrated age-related volume changes in the brain using MRI. 60 healthy individuals who had normal MRI aged from 20 years to 80 years were examined and classified into three groups: Group I: 21 persons; nine males and 12 females aging between 20-39 years old. Group II: 22 persons; 11 males and 11 females aging between 40-59 years old. Group III: 17 persons; eight males and nine females aging between 60-80 years old. Volumetric analysis was done to evaluate the effect of age, gender and hemispheric difference in the caudate and putamen by the slicer 4.3.3.1 software using 3D T1-weighted images. Data were analyzed by student's unpaired t test, ANOVA and regression analysis. The volumes of the measured and corrected caudate nuclei and putamen significantly decreased with aging in males. There was a statistically insignificant relation between the age and the volume of the measured caudate nuclei and putamen in females but there was a statistically significant relation between the age and the corrected caudate nuclei and putamen. There was no significant difference on the caudate and putamen volumes between males and females. There was no significant difference between the right and left caudate nuclei volumes. There was a leftward asymmetry in the putamen volumes. The results can be considered as a base to track individual changes with time (aging and CNS diseases). Clin.

Stable employment promotes recovery for persons with severe mental illness by enhancing income and quality of life, but its impact on mental health costs has been unclear. This study examined service cost over ten years among participants in a co-occurring disorders study. Latent-class growth analysis of competitive employment identified trajectory groups. The authors calculated annual costs of outpatient services and institutional stays for 187 participants and examined group differences in ten-year utilization and cost. A steady-work group (N=51) included individuals whose work hours increased rapidly and then stabilized to average 5,060 hours per person over ten years. A late-work group (N=57) and a no-work group (N=79) did not differ significantly in utilization or cost outcomes, so they were combined into a minimum-work group (N=136). More education, a bipolar disorder diagnosis (versus schizophrenia or schizoaffective disorder), work in the past year, and lower scores on the expanded Brief Psychiatric Rating Scale predicted membership in the steady-work group. These variables were controlled for in the outcomes analysis. Use of outpatient services for the steady-work group declined at a significantly greater rate than it did for the minimum-work group, while institutional (hospital, jail, or prison) stays declined for both groups without a significant difference. The average cost per participant for outpatient services and institutional stays for the minimum-work group exceeded that of the steady-work group by $166,350 over ten years. Highly significant reductions in service use were associated with steady employment. Given supported employment's well-established contributions to recovery, evidence of long-term reductions in the cost of mental health services should lead policy makers and insurers to promote wider implementation.

The cerebral metabolic rate for glucose (CMRglc) was measured with positron emission tomography and [18F]2-fluoro-2-deoxy-D-glucose in 14 healthy subjects with Down's syndrome, 19 to 33 years old, and in six healthy Down's syndrome subjects over 35 years, two of whom were demented. Dementia was diagnosed from a history of mental deterioration, disorientation and hallucinations. All Down's syndrome subjects were trisomy 21 karyotype. CMRglc also was examined in 15 healthy men aged 20-35 years and in 20 healthy men aged 45-64 years. All subjects were at rest with eyes covered and ears plugged. Mean hemispheric CMRglc in the older Down's syndrome subjects was significantly less, by 23%, than in the young Down's syndrome group; statistically significant decreases in regional metabolism (rCMRglc) also were present in all lobar regions. Comparison of the younger control group with the older control group showed no difference in CMRglc or any rCMRglc (p greater than 0.05). Assessment of language, visuospatial ability, attention and memory showed significant reductions in test scores of the old as compared with the young Down's syndrome subjects. These results show that significant age differences in CMRglc and rCMRglc occur in Down's syndrome but not in healthy controls, and that, although only some older Down's syndrome subjects are demented, significant age reductions in neuropsychologic variables occur in all of them.

To evaluate the effect of intraoperative mitomycin-C (MMC) on polypropylene Ahmed glaucoma valve (AGV) survival 2 years after implantation during the first 2 years of life. Retrospective institutional comparative series (1995-2005). Thirty-one eyes of 27 patients (23 unilateral, 4 bilateral; 16 boys, 11 girls) undergoing AGV implantation at a mean age of 11.1 months (standard deviation [SD], 5.46), all of which had 2 years of regular postoperative follow-up. MMC was applied intraoperatively in those cases in the area of AGV implantation in 16 (52%) and was not applied in 15 (48%). In some eyes, MMC was applied intraoperatively in cases done by the surgeons who routinely used MMC for all AGV implantation in young children. Failure was defined as intraocular pressure (IOP) > 22 mmHg with or without glaucoma medications, the need for an additional procedure for IOP control, or the occurrence of significant complications (e.g., endophthalmitis, retinal detachment, persistent hypotony [IOP < 5 mmHg]). Survival was the absence of failure. Failure or significant complications as defined. Mean survival for the non-MMC eyes (22.15 months; standard error [SE], 1.93) was significantly longer than survival for the MMC eyes (16.25 months; SE, 2.17) by the log-rank test (P = 0.025). The difference in cumulative survival at 2 years was also significantly different by log-rank test (P = 0.001): 80.0% (SE 10.3) and 31.3% (SE 11.6), respectively. Rather than improved survival, intraoperative use of MMC was associated with shorter survival 2 years after AGV implantation during the first 2 years of life. We speculate that MMC-induced tissue death can stimulate a reactive fibrosis around the AGV in very young eyes.
Effects of electrofishing gear type on spatial and temporal variability in fish community sampling
Meador, M.R.; McIntyre, J.P.
2003-01-01
Fish community data collected from 24 major river basins between 1993 and 1998 as part of the U.S. Geological Survey's National Water-Quality Assessment Program were analyzed to assess multiple-reach (three consecutive reaches) and multiple-year (three consecutive years) variability in samples collected at a site. Variability was assessed using the coefficient of variation (CV; SD/mean) of species richness, the Jaccard index (JI), and the percent similarity index (PSI). Data were categorized by three electrofishing sample collection methods: backpack, towed barge, and boat. Overall, multiple-reach CV values were significantly lower than those for multiple years, whereas multiple-reach JI and PSI values were significantly greater than those for multiple years. Multiple-reach and multiple-year CV values did not vary significantly among electrofishing methods, although JI and PSI values were significantly greatest for backpack electrofishing across multiple reaches and multiple years. The absolute difference between mean species richness for multiple-reach samples and mean species richness for multiple-year samples was 0.8 species (9.5% of total species richness) for backpack samples, 1.7 species (10.1%) for towed-barge samples, and 4.5 species (24.4%) for boat-collected samples. Review of boat-collected fish samples indicated that representatives of four taxonomic families - Catostomidae, Centrarchidae, Cyprinidae, and Ictaluridae - were collected at all sites. Of these, catostomids exhibited greater interannual variability than centrarchids, cyprinids, or ictalurids. Caution should be exercised when combining boat-collected fish community data from different years because of relatively high interannual variability, which is primarily due to certain relatively mobile species. Such variability may obscure longer-term trends.

The Evaluation of the US Department of Housing and Urban Development Lead-Based Paint Hazard Control Grant Program studied the effectiveness of the housing intervention performed in reducing the blood lead of children at four post-intervention times (6-months, 1-year, 2-years, and 3-years). A repeat measures analysis showed that blood lead levels declined up to three-years post-intervention. The results at each successive collection time were significantly lower than at the previous post-intervention time except for the difference between the levels at two and three years. At two-years post-intervention, geometric mean blood lead levels were approximately 37% lower than at pre-intervention. Children with pre-intervention blood lead levels as low as 10 μg/dL experienced substantial declines in blood lead levels. Previous studies have found substantial improvements only if a child's pre-intervention blood lead level was above 20 μg/dL. Individual interior lead hazard control treatments as grouped by Interior Strategy were not a significant predictor of post-intervention blood lead levels. However, children living in dwellings where exterior lead hazard control interventions were done had lower blood lead levels at one-year post-intervention than those living in dwellings without the exterior interventions (all other factors being equal), but those differences were only significant when the mean exterior paint lead loading at pre-intervention was about the 90th percentile (7.0mg/cm(2)). This observation suggests that exterior lead hazard control can be an important component of a lead hazard control plan. Children who were six to eleven months of age at pre-intervention had a significant increase in blood lead at one-year post-intervention, probably due to other exposures.

Aims: To determine the body size of extremely low birth weight (ELBW, birth weight 500–999 g) subjects in early adulthood. Methods: Cohort study examining the height and weight of 42 ELBW survivors free of cerebral palsy between birth and 20 years of age. Weight and height measurements were converted to Z (SD) scores. Results: At birth the subjects had weight Z scores substantially below zero (mean birth weight Z score -0.90, 95% CI -1.25 to -0.54), and had been lighter than average at ages 2, 5, and 8 years. However, by 14, and again at 20 years of age their weight Z scores were not significantly different from zero. At ages 2, 5, 8, 14, and 20 years of age their height Z scores were significantly below zero. Their height at 20 years of age was, however, consistent with their parents' height. As a group they were relatively heavy for their height and their mean body mass index (BMI) Z score was almost significantly different from zero (mean difference 0.42, 95% CI -0.02 to 0.84). Their mean BMI (kg/m2) was 24.0 (SD 5.2); 14 had a BMI >25, and four had a BMI >30. Conclusions: Despite their early small size, by early adulthood the ELBW subjects had attained an average weight, and their height was consistent with their parents' height. They were, however, relatively heavy for their height. PMID:15033844

The Effect of a State Department of Education Teacher Mentor Initiative on Science Achievement
NASA Astrophysics Data System (ADS)
Pruitt, Stephen L.
This study analyzed a state department of education's ability to have actual influence over the improvement of science achievement and proficiency by having direct relationships with science teachers in Georgia's lowest performing schools. The study employed a mixed ANOVA analysis of the mean scale scores and proficiency rates of the science portion of the Georgia High School Graduation Test (GHSGT) for the years 2004 through 2007 to determine if the intervention by the Science Mentor Program (SMP) had significant effect on the science achievement and proficiency within the cohort of schools, as compared to a set of schools receiving no intervention, on various subgroups within the schools, and on various levels of intervention within the SMP. All data used in this study are available to the public through the Georgia Department of Education (GaDOE). SMP schools were selected based on their level of intervention for three consecutive years. Non-SMP schools were selected based on demographic similarities in economically disadvantaged, white, African-American, and students with disabilities to ensure a match of pairings for analyses. The results of this study showed significant improvement of scale scores and proficiency rates between 2004 and 2007. The study showed significant increases in all schools regardless of treatment. The study also showed significant differences in performance within the subgroups. Males, white, non-Economically Disadvantaged, and regular education students were all found to have significantly better performance in both achievement and proficiency rate. Economically Disadvantaged students were found to have a significant difference with regard to treatment groups. There was a significant difference between the mean scale score and proficiency rates of Economically Disadvantaged students in schools receiving high-intervention and schools receiving no-intervention. Further analysis showed that the only significant difference was in 2004, the year prior to implementation. Results indicate while the high-intervention schools did perform lower over all four years, they were not significantly different during the time of treatment indicating high-intervention schools performed at levels equivalent to schools receiving no-intervention. This study provided evidence of the success of a specific intervention by a state education agency to improve science education for the practicing teacher and its role in improving student science achievement. It will be used by policymakers to determine future activities and potential funding of other such programs. This also has a potential for national use as it is the only program of this nature operated by a department of education in the country.

To improve understanding of the distribution of ecologically important, ephemeral wetland habitats across the Great Plains, the occurrence and distribution of surface water in playa wetland complexes were documented for four different years across the Great Plains Landscape Conservation Cooperative (GPLCC) region. This information is important because it informs land and wildlife managers about the timing and location of habitat availability. Data with an accurate timestamp that indicate the presence of water, the percent of the area inundated with water, and the spatial distribution of playa wetlands with water are needed for a host of resource inventory, monitoring, and research applications. For example, the distribution of inundated wetlands forms the spatial pattern of available habitat for resident shorebirds and water birds, stop-over habitats for migratory birds, connectivity and clustering of wetland habitats, and surface waters that recharge the Ogallala aquifer; there is considerable variability in the distribution of playa wetlands holding water through time. Documentation of these spatially and temporally intricate processes, here, provides data required to assess connections between inundation and multiple environmental drivers, such as climate, land use, soil, and topography. Climate drivers are understood to interact with land cover, land use and soil attributes in determining the amount of water that flows overland into playa wetlands. Results indicated significant spatial variability represented by differences in the percent of playas inundated among States within the GPLCC. Further, analysis-of-variance comparison of differences in inundation between years showed significant differences in all cases. Although some connections with seasonal moisture patterns may be observed, the complex spatial-temporal gradients of precipitation, temperature, soils, and land use need to be combined as covariates in multivariate models to effectively account for these patterns. We demonstrate the feasibility of using classification of Landsat satellite imagery to describe playa-wetland inundation across years and seasons. Evaluating classifications representing only 4 years of imagery, we found significant year-to-year and state-to-state differences in inundation rates.

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

The aim of this study was to test whether posterior zirconia-ceramic (ZC) and metal-ceramic (MC) fixed dental prostheses (FDPs) exhibit similar survival and technical/biologic complication rates. A total of 58 patients in need of 76 posterior FDPs were randomly assigned to receive 40 ZC and 36 MC FDPs. The restorations were examined at baseline (cementation) and yearly for 5 years. Technical and biologic outcomes were compared. The independent treatment groups were compared with nonparametric Mann-Whitney test for metric variables and with Fisher exact test for categoric data. A total of 52 patients with 40 ZC and 29 MC FDPs were examined at 5 years. No FDP failed during the 5 years; 2 ZC FDPs failed at 65.4 and 73.3 months. Debonding occurred at 3 ZC FDPs. Technical outcomes (modified US Public Health Service criteria) and general periodontal parameters did not show significant differences between ZC and MC FDPs. ZC FDPs exhibited similar outcomes to MC FDPs based on 5-year survival estimates. The majority of technical and biologic outcome measures were not significantly different.

to describe the prevalence of dental caries and the supply of dental care in the population of Xingu Indigenous Park, Brazil, at 5, 12 and 15-19 years old, in 2007 and 2013. cross-sectional study panel, with secondary data provided by the Indigenous Special Sanitary District of Xingu and Project Xingu. 368 indigenous people were examined in 2007 and 423 in 2013; there was no significant difference between the means of the number of decayed, missing and filled teeth at 5 years (6.43 [2007], 5.85 [2013]; p=0.29), and at 12 years (2.54 [2007], 2.78 [2013]; p=0.81); this difference was significant at 15-19 years (6.89 [2007], 4.65 [2013]; p<0.01); the dental care index decreased from 21.7 to 7.1%, 44.1 to 16.4%, and 63.1 to 41.1%, respectively at 5, 12, and 15-19 years. the prevalence of caries remained high in children, with a reduction in adolescents (15-19 years old); there was a decrease in the supply of dental care.
Testing the effects of expression, intensity and age on emotional face processing in ASD.

Individuals with autism spectrum disorder (ASD) commonly show global deficits in the processing of facial emotion, including impairments in emotion recognition and slowed processing of emotional faces. Growing evidence has suggested that these challenges may increase with age, perhaps due to minimal improvement with age in individuals with ASD. In the present study, we explored the role of age, emotion type and emotion intensity in face processing for individuals with and without ASD. Twelve- and 18-22- year-old children with and without ASD participated. No significant diagnostic group differences were observed on behavioral measures of emotion processing for younger versus older individuals with and without ASD. However, there were significant group differences in neural responses to emotional faces. Relative to TD, at 12 years of age and during adulthood, individuals with ASD showed slower N170 to emotional faces. While the TD groups' P1 latency was significantly shorter in adults when compared to 12 year olds, there was no significant age-related difference in P1 latency among individuals with ASD. Findings point to potential differences in the maturation of cortical networks that support visual processing (whether of faces or stimuli more broadly), among individuals with and without ASD between late childhood and adulthood. Finally, associations between ERP amplitudes and behavioral responses on emotion processing tasks suggest possible neural markers for emotional and behavioral deficits among individuals with ASD.

HIV status may affect outcomes after definitive chemoradiotherapy for anal cancer. Here, we report a large series in the highly active antiretroviral therapy era comparing outcomes between HIV-positive and HIV-negative patients with anal cancer. This was a retrospective chart review. The study was conducted at an outpatient oncology clinic at large academic center. A total of 107 patients were reviewed, 39 HIV positive and 68 HIV negative. All of the patients underwent definitive chemoradiation for anal cancer. Data on patient characteristics, treatment, toxicity, and outcomes were collected. Overall survival, colostomy-free survival, local recurrence-free survival, and distant metastasis-free survival were analyzed. Median follow-up was 15 months. HIV-positive patients were younger (median, 52 vs 64 years; p < 0.001) and predominantly men (82% men vs 49% men; p = 0.001). There were no significant differences in T, N, or stage groups. HIV-positive patients had a significantly longer duration from biopsy to start of chemoradiation (mean number of days, 82 vs 54; p = 0.042). There were no differences in rates of acute toxicities including diarrhea, fatigue, or dermatitis. HIV-positive patients had significantly higher rates of hospitalization (33% vs 15%; p = 0.024). The 3-year overall survival rate was 42% in HIV-positive and 76% in HIV-negative patients (p = 0.037; HR, 2.335 (95% CI, 1.032-5.283)). Three-year colostomy-free survival was 67% in HIV-positive and 88% in HIV-negative patients (p = 0.036; HR, 3.231 (95% CI, 1.014-10.299)). Differences in overall survival rates were not significant on multivariate analysis. This study was limited by its retrospective design and small patient numbers. In this cohort, HIV-positive patients had significantly worse overall and colostomy-free survival rates than HIV-negative patients. However, differences in survival were not significant on multivariate analysis. Additional studies are necessary to establish the etiology of this difference.

Tuberculosis and carcinomatosis are the two most frequent causes of pleural effusion and exudative ascites, and both are characterized by lymphocyte-rich effusion. We attempted to discover if there is any significant difference in the age and sex distribution between patients presenting with these two conditions. A total of 161 serous effusion samples from 127 patients (89 with pleural effusion and 38 with ascites) having follow-up biopsy and histopathological examination were included in the present study. Three groups - malignancy (47 patients), tuberculosis (47) and non-tuberculous benign lesions (26) as per histopathological diagnoses - were compared in respect to age and sex distribution. A total of 29 (61.7%) patients with malignancy were aged ≥50 years as compared with three (6.4%) tuberculosis patients with serous effusions (P = 0.00000). A similar trend was observed in the ≥60 years age group (18 or 38.3% malignancy vs none with tuberculosis, P = 0.00000). A total of 36 (76.6%) tuberculous effusion patients were aged less than 40 years as opposed to eight (17.0%) patients with malignant effusions (P = 0.00000). There was also s significant difference between tuberculous and non-tuberculous benign lesions in the ≥50 years age group (6.4% vs 69.2%, P = 0.00000), but no significant difference between malignancy and non-tuberculous benign lesions (P = 0.61385). There were 31 female (66.0%) patients with malignancy, which was significantly higher than that of patients with tuberculosis (16, [34%], P = 0.00365) and non-specific inflammation/benign lesions (23.1%, P = 0.00059). However, the difference between tuberculosis and non-tuberculous benign lesions was not significant (P = 0.42756). Whereas malignancy in serous effusions is found in older and middle-aged people, tuberculous effusion is a disease of younger people. © 2014 Japan Geriatrics Society.
Home range behavior among box turtles (Terrapene c. carolina) of a bottomland forest in Maryland
Stickel, L.F.
1989-01-01
Eastern box turtles (Terrapene c. carolina) in a Maryland bottomland forest were studied over a period of years (1944-1981). Home ranges of 51 males averaged 146 + SD 48 m long and 105 + SD 38 m wide; ranges of 52 females averaged 144 + SD 52 m long and 100 + SD 38 m wide. An approximation of average home range size, based on an ellipse, is 1.20 ha for males and 1.13 ha for females. Sizes of home ranges of individuals did not differ significantly between 1945 and the full term of their captures (0 =14 yr) (AOV; P > 0.05). Mean distance between capture sites, which provides an index to range size, was not significantly different among the years of 1945, 1955, 1965, and 1975 (AOV; P > 0.05). Geographic centers of ranges of 77 males in the bottomlands showed no significant (AOV; P > 0.05) change for 46, and change over relatively short distances (0 =57 + SD 23 m) for the others. Among 70 females, there was no significant change for 46 and change over short distances (0=61 + SD 24 m) for the others. Changes in location were more frequent between 1965 and 1975, a period of pronounced population decline, than between previous decades (significant only for females, x2 P < 0.025). Hibernation sites ordinarily (21 of 23 Individuals) were within the normal bottom]and range; hibernation sites of different years were near each other (all of 4 individuals). In contrast, nesting sites were far distant, extending the home range by 400-700 m, but those of different years were near each other (6 individuals). Mating partners occupied broadly overlapping or contiguous ranges (35 records). Interactions between males (18 records) were identical to courtship behavior, and are believed not to represent territorial aggression.

This clinical descriptive study aims to establish if differences exist in functional outcomes, to include both leg and lower back pain (LBP) as well as disability, in patients undergoing laminectomy or laminotomy surgery for lumbar spinal stenosis (LSS). We conducted a single centre, prospective study of 119 patients undergoing laminectomy or laminotomy surgery for LSS, from 2006 and 2012. Clinical outcomes for back and leg pain were analyses using Oswestry Disability Index (ODI) questionnaires and visual analogue scale (VAS) scores collected preoperatively, at 6 weeks and 1 year. Further analysis subdivided patients into two groups based on initial LBP VAS scores. Fifty-five percent of patients were females (n=65) and 45% males (n=54), with a mean age of 68.7 years and L4/5 being the level most frequently decompressed. Considering all surgeries, a statistically significant reduction in VAS back pain between pre-op and 6 weeks was seen (4.99 to 3.00, P<0.001). There was a significant (P<0.0001) average reductions in LBP by 1.66 units and leg pain by 3.33 units after 1 year, with minimal difference between laminectomy and laminotomy. In the VAS back ≥5 group, laminectomy patient's pain increased by 0.63 units between 6 weeks and 1 year whilst laminotomy patients experienced a reduction in back pain of 0.51 units (P=0.063). ODI scores significantly improved for laminectomy and laminotomy by an average of 19.1%, 95% CI: 13.4-24.9% and 10.8%, 95% CI: 5.8-15.7%, with no statistically significant difference between groups. No statistically significant differences were demonstrated between laminectomy and laminotomy outcomes, for LBP, leg pain or disability in our institute. On the basis of functional outcomes laminectomy remains a feasible approach in the treatment of lumbar spine stenosis. The data presented in this manuscript provides frequency data for subsequent comparative studies.

Activated coagulation and fibrinolytic system in cancer patients is associated with tumor stroma formation and metastasis in different cancer types. The aim of this study is to explore the correlation of blood coagulation assays for various clinicopathologic factors in breast cancer patients. A total of 123 female breast cancer patients were enrolled into the study. All the patients were treatment naïve. Pretreatment blood coagulation tests including PT, APTT, PTA, INR, D-dimer, fibrinogen levels, and platelet counts were evaluated. Median age of diagnosis was 51 years old (range 26-82). Twenty-two percent of the group consisted of metastatic breast cancer patients. The plasma level of all coagulation tests revealed statistically significant difference between patient and control group except for PT (p<0.001 for all variables except for PT; p=0.08). Elderly age (>50 years) was associated with higher D-dimer levels (p=0.003). Metastatic patients exhibited significantly higher D-dimer values when compared with early breast cancer patients (p=0.049). Advanced tumor stage (T3 and T4) was associated with higher INR (p=0.05) and lower PTA (p=0.025). In conclusion, coagulation tests show significant differences in patients with breast cancer.

Over a 6-year period, an epidemiological study of human infection by Fasciola hepatica in the Northern Bolivian Altiplano was carried out. Prevalences and intensities were analysed from coprological results obtained in 31 surveys performed in 24 localities and proved to be the highest known so far. The global prevalence was 15.4%, with local prevalences ranging from 0% to 68.2%. Significant differences between prevalence rates were detected and the highest prevalences were in subjects aged < 20 years. However, prevalences showed no gender difference. The global intensity (eggs per gram of faeces, epg) ranged from 24 to 5064 epg and showed arithmetic and geometric means respectively of 446 and 191 epg, with highest local arithmetic and geometric means of 1345 and 678 epg. Significant differences in mean egg output were detected between localities. The significantly higher F. hepatica egg counts shown by girls in school surveys is worth mentioning. Although the distributions of intensities according to age-groups did not show any significant difference, a decrease of egg output counts with an increase of age was detected. It is concluded that fascioliasis is a very important human health problem in this region.

Purpose: To determine the effects of boost volume (BV) in relation to margin status and tumor size on the development of local recurrence with breast-conserving therapy. Methods and Materials: Between 1983 and 1995, 1,073 patients with invasive breast cancer underwent 1,101 breast-conserving therapies. Of these 1,101 BCTs, 967 were eligible for analysis. The BV was categorized into tertiles: <66 cm{sup 3} (n = 330), 66-98 cm{sup 3} (n = 326), and >98 cm{sup 3} (n = 311). The median follow-up was 141 months. Separate analyses were done for women {<=}40 years and >40 years. Results: No significant difference in localmore » recurrence was shown between the tertiles and the recurrence site. The 15-year local recurrence-free survival rate was 87.9% for the first tertile, 88.7% for the second, and 89% for the third. For women {<=}40 years old, the corresponding 15-year local recurrence-free survival rate was 80%, 74.5%, and 69.2%. For women >40 years old, the corresponding rate was 88.7%, 89.5%, and 90.9%. At 5 years, women >40 years old had significantly more local failures in the first tertile; this difference disappeared with time. A test for trend showed significance at 5 years (p = 0.0105) for positive margins for ductal carcinoma in situ in women >40 years of age. Conclusion: The results of this study have shown that the size of the external BV has no major impact on local control. For women >40 years old, positive margins for ductal carcinoma in situ showed a trend with respect to BV at 5 years. The BV had no influence on local control in the case of positive margins for invasive carcinoma.« less

We aimed to examine the effect of a large population-based multifactorial screening and lifestyle intervention programme on 10-year incidence of diabetes. In a randomised trial of the general Danish population initiated in 1999-2001 59,616 men and women aged 30-60years were assigned to a five year screening and lifestyle counselling programme (n=11,629) or control group (n=47,987) and followed for ten years in nationwide registers. Intention to treat was applied and risk of diabetes was modeled by Cox regression and expressed as hazard ratios (HRs). We found that 1692 individuals had diabetes at baseline. Among 57,924 individuals without diabetes at baseline, 1267 emigrated, 2593 died and 3369 (Intervention group=684, Control group=2685) developed diabetes. We saw no significant difference in diabetes incidence between the groups after 10-year follow-up (Grey's test: p=0.22). In the first year of follow-up, incidence of diabetes was significantly higher in the intervention group than the control group (HR=1.68, 95%CI 1.29 to 2.29). We observed no difference in incidence of diabetes between the groups in the follow-up intervals from 1 to 6years or after 6-10years (HR=0.94, 0.83 to 1.06; HR=1.03, 0.91 to 1.17). Inviting the general population to participate in a repeated screening and lifestyle counselling programme over five years did not result in lower incidence of diabetes after 10years of follow-up. As expected, significantly more individuals were diagnosed with diabetes in the intervention group during the first year, but this was not followed by a decrease in the following years.

Multiple studies have found that children born to mothers with opioid or poly-substance use during pregnancy have more behavior and attention problems and lower cognitive functioning than non-exposed children. The present study aimed to investigate whether behavior and attention problems are more prominent than general cognitive deficits in this risk group and whether the problems wane or increase over time. This prospective longitudinal cross-informant study compared 72 children who were prenatally exposed to heroin and multiple drugs with a group of 58 children without known prenatal risk factors. Group differences in caregivers’ and teachers’ reports of the children’s behavior and attention problems based on the Child Behavior Check List and the ADHD Rating Scale were compared based on group differences in general cognitive functioning at 4 ½ and 8 ½ years of age. Both parent and teacher reports suggest that the exposed group has significantly more problems in several behavioral areas than the comparison group, particularly with regard to attention problems. The preschool teachers had already reported these problems when the children were 4 ½ years old, whereas the caregivers reported these problems mainly when the children were 8 ½ years old. The group differences in behavioral and attentional problems were not significantly greater and some were even significantly smaller than the group differences in general cognitive abilities. These findings suggest that children subject to prenatally drug exposure have increasing problems in multiple areas related to behavior from preschool age to 8 ½ years but that these problems do not seem to be specific; i.e., they are not more severe than the problems with general cognitive abilities found for this group.

Purpose. To investigate visual activities before and after the onset of juvenile myopia. Methods. The subjects were 731 incident myopes (−0.75 D or more myopia on cycloplegic autorefraction in both meridians) and 587 emmetropes (between −0.25 and +1.00 D) in the Collaborative Longitudinal Evaluation of Ethnicity and Refractive Error (CLEERE) Study. Parents supplied visual activity data annually. Data from myopic children 5 years before through 5 years after myopia onset were compared to data from age-, sex-, and ethnicity-matched models of children who remained emmetropic. Results. Hours per week spent reading or using a computer/playing video games did not differ between the groups before myopia onset; however, hours per week for both activities were significantly greater in myopes than in emmetropes at onset and in 4 of the 5 years after onset by 0.7 to 1.6 hours per week. Hours per week spent in outdoor/sports activities were significantly fewer for children who became myopic 3 years before onset through 4 years after onset by 1.1 to 1.8 hours per week. Studying and TV watching were not significantly different before myopia onset. Conclusions. Before myopia onset, near work activities of future myopic children did not differ from those of emmetropes. Those who became myopic had fewer outdoor/sports activity hours than the emmetropes before, at, and after myopia onset. Myopia onset may influence children's near work behavior, but the lack of difference before onset argues against a major causative role for near work. Less outdoor/sports activity before myopia onset may exert a stronger influence on development than near work. PMID:20926821

Purpose To compare refractive and visual outcomes, patient satisfaction, and complication rates among different age categories of patients who underwent refractive lens exchange (RLE). Methods A stratified, simple random sample of patients matched on preoperative sphere and cylinder was selected for four age categories: 45–49 years (group A), 50–54 years (group B), 55–59 years (group C), and 60–65 years (group D). Each group contained 320 patients. All patients underwent RLE with a multifocal intraocular lens at least in one eye. Three months postoperative refractive/visual and patient-reported outcomes are presented. Results The percentage of patients that achieved binocular uncorrected distance visual acuity 20/20 or better was 91.6% (group A), 93.8% (group B), 91.6% (group C), 88.8% (group D), P=0.16. Binocularly, 80.0% of patients in group A, 84.7% in group B, 78.9% in group C, and 77.8% in group D achieved 20/30 or better uncorrected near visual acuity (P=0.13). The proportion of eyes within 0.50 D of emmetropia was 84.4% in group A, 86.8% in group B, 85.7% in group C, and 85.8% in group D (P=0.67). There was no statistically significant difference in postoperative satisfaction, visual phenomena, dry eye symptoms, distance or near vision activities. Apart from higher rate of iritis in the age group 50–55 years, there was no statistically significant difference in postoperative complication rates. Conclusion RLE can be safely performed in younger as well as older presbyopes. No significant difference was found in clinical or patient-reported outcomes. PMID:28894356
Health Conditions and Racial Differences Among Justice-Involved Adolescents, 2009 to 2014.
Winkelman, Tyler N A; Frank, Joseph W; Binswanger, Ingrid A; Pinals, Debra A
Providers can optimize care for high-risk adolescents by understanding the health risks among the 1 million US adolescents who interact with the justice system each year. We compared the prevalence of physical health, substance use, and mood disorders among adolescents with and without recent justice involvement and analyzed differences according to race/ethnicity. Cross-sectional analysis using the 2009 to 2014 National Survey on Drug Use and Health. Prevalence data were adjusted for sociodemographic differences between adolescents with and without justice involvement. Justice-involved adolescents had a history of past year arrest, parole/probation, or juvenile detention. Our sample consisted of adolescents aged 12 to 17 years with (n = 5149) and without (n = 97,976) past year justice involvement. In adjusted analyses, adolescents involved at any level of the justice system had a significantly higher prevalence of substance use disorders (P < .001), mood disorders (P < .001), and sexually transmitted infections (P < .01). Adolescents on parole/probation or in juvenile detention in the past year had a higher prevalence of asthma (P < .05) and hypertension (P < .05) compared with adolescents without justice involvement. Among justice-involved adolescents, African American adolescents were significantly less likely to have a substance use disorder (P < .001) or mood disorder (P < .01) compared with white or Hispanic adolescents, but had significantly higher prevalence of physical health disorders (P < .01). Adolescents involved at all levels of the justice system have high-risk health profiles compared with the general adolescent population, although these risks differ across racial/ethnic groups. Policymakers and health care providers should ensure access to coordinated, high-quality health care for adolescents involved at all levels of the justice system. Published by Elsevier Inc.

The most used verbal fluency paradigms are semantic and letter fluency tasks. Studies suggest that these paradigms access semantic memory and executive function and are sensitive to frontal lobe disturbances. There are few studies in Brazilian samples on these paradigms. Objective The present study investigated performance, and the effects of age, on verbal fluency tasks in Brazilian children. The results were compared with those of other studies, and the consistency of the scoring criteria data is presented. Methods A sample of 119 children (7 to 10 years old) was submitted to the three phonemic fluency (F, A, M) tasks and three semantic fluency (animals, clothes, fruits) tasks. The results of thirty subjects were scored by two independent examiners. Results A significant positive correlation was found between the scores calculated by the two independent examiners. Significant positive correlations were found between performance on the semantic fluency task and the phonemic fluency task. The effect of age was significant for both tasks, and a significant difference was found between the 7- and 9-year-old subjects and between the 7- and 10-year-old subjects. The 8-year-old group did not differ to any of the other age groups. Conclusion The pattern of results was similar to that observed in previous Brazilian and international studies. PMID:29213727

A survey of 1691 first-and final-year students in the helping professions (medicine, law, nursing, pharmacy, police science, seminary, social work/ psychology, and teaching) as to their use of drugs was carried out during February to April, 1980, in Brisbane, Australia. The results indicated that about 86% drank coffee or tea, 85% drank alcohol, 85% used non-prescription analgesics, 31% used tobacco, 25% antihistamines, 9% marijuana, 9% sedatives, 6% tranquilizers, 2% hallucinogens, 2% stimulants, 1% cocaine and 1% used opiates at least once a year. Of these students, females used analgesics and antihistamines significantly more frequently than males and consumed more caffeine, tobacco and analgesics than males, while males drank significantly more alcohol than females. Final-year students used more alcohol, coffee or tea and tobacco, and used marijuana, coffee and tea and tobacco significantly more frequently than first-year students. Individuals who did not consider religion important used more alcohol and tobacco and used marijuana, tobacco and hallucinogens more frequently compared to individuals who considered religion to be important. There was also a significant difference in drug usage between the different courses of study for most of the substances, with law students using the majority of substances the most frequently and seminarians the least frequently.

Previous cross-sectional studies and 6-year longitudinal study have demonstrated that home blood pressure (HBP) measurements upon awakening have a stronger predictive power for death, micro- and macrovascular complications than clinic blood pressure (CBP) measurements in patients with type 2 diabetes (T2DM). This study investigated which of these measurements offers stronger predictive power for outcomes over 10 years. At baseline, 400 Japanese patients with T2DM were classified as having hypertension (HT) or normotension (NT) based on HBP and CBP. The mean survey duration was 95 months. Primary and secondary end-points were death and new or worsened micro- and macrovascular complications, respectively. Differences in outcomes for each end-point between HT and NT patients were analyzed using Kaplan-Meier survival curves and log-rank testing. Associated risk factors were assessed using Cox proportional hazards analysis. Based on HBP, death and micro- and macrovascular complications were significantly higher in patients with HT than with NT at baseline and end-point. Based on CBP, there were no significant differences in incidence of death, micro- or macrovascular complications between patients with HT and NT at baseline and end-point, although a significant difference in incidence of death was observed between the HT and NT groups at end-point. However, the significance was significantly lower in CBP than in HBP. One risk factor associated with micro- and macrovascular complications in patients with HBP was therapy for HT. This 10-year longitudinal study of patients with T2DM demonstrated that elevated HBP upon awakening is predictive of death, and micro- and macrovascular complications.
In Search of Emerging Same-Sex Sexuality: Romantic Attractions at Age 13 Years.
Li, Gu; Hines, Melissa
2016-10-01
Sex-typed behavior in childhood is significantly related to sexual orientation in adulthood. In addition, same-sex attractions in early adolescence are more non-exclusive than in adulthood and can differ from later same-sex orientations. However, little research has focused on romantic attractions as they emerge during early adolescence. Drawing a sample from the Avon Longitudinal Study of Parents and Children (197 girls, 204 boys), the current study examined whether same-sex romantic attractions at age 13 years were exclusive, and whether they were predicted by sex-typed behavior at age 3.5 years. No young adolescents in this sample reported exclusive same-sex attractions, and increased same-sex attractions were not significantly related to reduced other-sex sexualities. Childhood sex-typed behavior did not significantly predict early same-sex attractions, suggesting that early same-sex attractions differ from later same-sex orientations. The current study highlights the importance of studying the development of sexuality beginning prior to adulthood.

Eating habits may have a key influence on cognitive function, however, the relationship between dietary intake and cognitive impairment in the elderly Chinese population has not been explored. The present study investigated the association between cognitive impairment and eating habits in elderly Chinese subjects >90 years of age. This study comprised data from subjects included in the 2005 Project of Longevity and Ageing in Dujiangyan, China. Subjects were divided into two groups: cognitive impairment group and normal group. Sociodemographic and dietary habit data were collected and cognitive function was assessed in all subjects using the Mini-Mental State Examination. Data from 763 subjects (249 men, 514 women) were included. There was no statistically significant difference in eating habits between the two groups. Education level in the cognitive impairment group was significantly lower than in the normal group. Significant between-group differences were detected in factors relating to subjects' professions. Eating habits were not related to cognitive impairment in elderly Chinese people >90 years of age.

Context Extremely low birth weight (ELBW, <1kg) children have high rates of chronic conditions during childhood. Information on their trajectory of health during the critical period of adolescence is needed for health care planning. Objective To examine changes in rates of chronic conditions between age 8 and 14 years among ELBW compared to normal birth weight (NBW) controls. Design, Setting and Participants Cohort study conducted from 2004 through2009 of 181 ELBW children (weight <1kg) and 115 NBW controls of similar sociodemographic status born 1992 through 1995 in Cleveland, Ohio. Main Outcome Measures Rates of chronic conditions overall (measured with the revised Questionnaire for Identifying Children with Chronic Conditions) and rates of asthma and obesity. Results The overall rates of chronic conditions did not change significantly between ages 8 and 14 years among ELBW children (75% at age 8 years vs 74% at age 14 years) or NBW controls (37% at 8 years vs 47% at age 14 years). In generalized estimating equations logistic regression, adjusting for sociodemographic status, sex and race, ELBW continued to have higher rates of chronic conditions than NBW controls at age 14 years (74% vs 47%, respectively adjusted odds ratio [AOR],2.8; 95% Confidence Interval {CI},1.7 to 4.6). Rates of asthma requiring medication did not change between 8 and 14 years among ELBW children (23% at both ages), but increased among NBW children from 8% at age 8 years to 17% at age 14 years (p=0.002). Differences in rates of asthma between ELBW and NBW children were no longer significant at the age of 14 years (23% vs 17%, respectively; AOR,1.5; [95%CI,0.8 to 2.8]. Mean z scores for body mass index increased in ELBW children from 0.06 at age 8 yesrs to 0.38 at age 14 years(p<0.001) and rates of obesity increased from 12% at age 8 years to 19% at age 14 years (p=0.02). However, the scores and rates did not change among NBW controls such that at the age of 14 years the differences between ELBW and NBW children in mean z-scores for body mass index (0.38 vs 0.56, respectively; adjusted mean difference −0.2; 95% CI, −0.5 to 0.1) or rates of obesity (19% vs 20%, respectively; AOR,1.1 [95%CI, 0.6to 2.0] were not significant.. Conclusions Among ELBW children rates of overall chronic conditions and asthma did not change between the ages of 8 and 14 years but the rates of obesityincreased. Compared with NBW controls, the rates of chronic conditions were higher but there were no significant differences in the rates of asthma or obesity. PMID:21791688

Objective To evaluate 4-year longitudinal change in thigh muscle and adipose tissue content in chronically painful versus painless knees. Methods Knees from Osteoarthritis Initiative participants with non-acceptable symptom status (numerical rating scale ≥4) and frequent pain (≥6 months at baseline, year 2 and year 4 follow-up) were studied. These were matched with painless controls (bilateral NRS pain intensity≤1 and ≤infrequent pain at all 3 timepoints). 4-year longitudinal changes in thigh muscle anatomical cross-sectional areas (CSAs), isometric muscle strength, and in subcutaneous (SCF) and intermuscular fat (IMF) CSAs were obtained from magnetic resonance images (MRI) and were compared between groups (paired t-tests). Results 43 participants fulfilled the inclusion criteria of chronic pain, had complete thigh muscle MRI acquisitions and strength measurements, and a matched control. Quadriceps CSAs, but not extensor strength, showed a significant longitudinal decrease in chronically painful knees (-3.9%; 95%confidence interval [95 CI] -6.3%,-1.5%) and in painless controls (-2.4%; 95% CI -4.1%, -0.7%); the difference in change was not statistically significant (p=0.33). There was a significant 4-year gain in SCF in painful knees (8.1%; 95% CI 3.1%, 13%) but not in controls (0.0%; 95%CI -4.4%, +4.4%) with the difference in change being significant (p=0.03). The gain in IMF (∼5.2%) was similar between painful and painless knees. Conclusion This is the first paper to show a significant impact of (chronic) knee pain on longitudinal change in local subcutaneous adipose tissue. The effect of pain on subcutaneous fat appeared stronger than that on intermuscular adipose tissue and on muscle status. PMID:25887367

A preliminary study was conducted on 50 children in the age group of 4-12 years, who were divided into two groups on the basis of decayed, missing and filled teeth (DMFT) i.e. Group A (1-3) and Group B (> 3). A 5-day diet diary was evaluated and Sweet Score, Total Sugar Exposure, At Meal Sugar Exposures and Between Meal Sugar Exposure were calculated. There was statistically significant difference between the two groups in relation to Sweet Score and Total sugar Exposures. Between Meal Sugar Exposure and At Meal sugar exposure did not differ significantly.

Multiple pulses can often be distinguished in the clicks of sperm whales (Physeter macrocephalus). Norris and Harvey [in Animal Orientation and Navigation, NASA SP-262 (1972), pp. 397-417] proposed that this results from reflections within the head, and thus that interpulse interval (IPI) is an indicator of head length, and by extrapolation, total length. For this idea to hold, IPIs must be stable within individuals, but differ systematically among individuals of different size. IPI stability was examined in photographically identified individuals recorded repeatedly over different dives, days, and years. IPI variation among dives in a single day and days in a single year was statistically significant, although small in magnitude (it would change total length estimates by <3%). As expected, IPIs varied significantly among individuals. Most individuals showed significant increases in IPIs over several years, suggesting growth. Mean total lengths calculated from published IPI regressions were 13.1 to 16.1 m, longer than photogrammetric estimates of the same whales (12.3 to 15.3 m). These discrepancies probably arise from the paucity of large (12-16 m) whales in data used in published regressions. A new regression is offered for this size range.

Evidence shows that prolonged sitting is associated with an increased risk of mortality, independent of physical activity (PA). The aim of the study was to identify correlates of sedentary time (ST) in different age groups and day types (i.e. school-/work day versus non-school-/non-work day). The study sample consisted of 1895 Dutch children (4-11 years), 1131 adolescents (12-17 years), 8003 adults (18-64 years) and 1569 elderly (65 years and older) who enrolled in the Dutch continuous national survey 'Injuries and Physical Activity in the Netherlands' between 2006 and 2011. Respondents estimated the number of sitting hours during a regular school-/workday and a regular non-school/non-work day. Multiple linear regression analyses on cross-sectional data were used to identify correlates of ST. Significant positive associations with ST were observed for: higher age (4-to-17-year-olds and elderly), male gender (adults), overweight (children), higher education (adults ≥ 30 years), urban environment (adults), chronic disease (adults ≥ 30 years), sedentary work (adults), not meeting the moderate to vigorous PA (MVPA) guideline (children and adults ≥ 30 years) and not meeting the vigorous PA (VPA) guideline (4-to-17-year-olds). Correlates of ST that significantly differed between day types were working hours and meeting the VPA guideline. More working hours were associated with more ST on school-/work days. In children and adolescents, meeting the VPA guideline was associated with less ST on non-school/non-working days only. This study provides new insights in the correlates of ST in different age groups and thus possibilities for interventions in these groups. Correlates of ST appear to differ between age groups and to a lesser degree between day types. This implies that interventions to reduce ST should be age specific. Longitudinal studies are needed to draw conclusions on causality of the relationship between identified correlates and ST.

Oral meal consumption increases glucagon-like peptide 1 (GLP-1) release which maintains euglycemia by increasing insulin secretion. This effect is exaggerated during short-term follow-up of Roux-en-y gastric bypass (RYGB). We examined the durability of this effect in patient with type 2 diabetes (T2DM) >10 years after RYGB. GLP-1 response to a mixed meal in the 10-year post-RYGB group (n = 5) was compared to lean (n = 9), obese (n = 6), and type 2 diabetic (n = 10) controls using a cross-sectional study design. Analysis of variance (ANOVA) was used to evaluate GLP-1 response to mixed meal consumption from 0 to 300 min, 0-20 min, 20-60 min, and 60-300 min, respectively. Weight, insulin resistance, and T2DM were also assessed. GLP-1 response 0-300 min in the 10-year post-RYGB showed a statistically significant overall difference (p = 0.01) compared to controls. Furthermore, GLP-1 response 0-20 min in the 10-year post-RYGB group showed a very rapid statistically significant rise (p = 0.035) to a peak of 40 pM. GLP-1 response between 20 and 60 min showed a rapid statistically significant (p = 0.041) decline in GLP-1 response from ~40 pM to 10 pM. GLP-1 response in the 10-year post-RYGB group from 60 to 300 min showed no statistically significant difference from controls. BMI, HOMA, and fasting serum glucose before and >10 years after RYGB changed from 59.9 → 40.4, 8.7 → 0.88, and 155.2 → 87.6 mg/dl, respectively, and were statistically significant (p < 0.05). An exaggerated GLP-1 response was noted 10 years after RYGB, strongly suggesting a durability of this effect. This phenomenon may play a key role in maintaining type 2 diabetes remission and weight loss after RYGB.

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

Background This study aimed to examine age-related, interindividual, and right/left differences in anterior-posterior foot pressure ratio in 764 preschool children (364 boys and 400 girls) aged 3.5-6.5 years. Methods Subjects maintained an upright standing posture for 10 seconds on the Footview Clinic, an instrument designed to calculate the anterior-posterior foot pressure ratio. The ratio of anterior foot pressure in each subject’s right and left feet was selected as a variable, and the mean of a 10 s measurement was used for analysis. Results The ratio of anterior foot pressure was significantly larger in the right foot than in the left foot. With regard to age, the ratio of anterior foot pressure was significantly larger in children aged over 4.5 years than in children aged 3.5 years. It was also larger in children aged 6 and 6.5 years than in children aged 4 years. Interindividual differences in variables were large, and coefficients of variance were highest in children aged 3.5 years and lowest in children aged 6.5 years. Conclusions In conclusion, anterior foot pressure increases with age in preschool children. Interindividual differences in anterior foot pressure are large and tend to decrease with age. Furthermore, the anterior foot pressure is slightly higher in the right foot than in the left foot. These results will be useful for various studies, such as examining relationships between the anterior-posterior foot pressure ratio and factors, such as untouched toes, physical fitness, and level of exercise.

To assess autistic symptom differences between high-functioning atypical autism (atypical symptomatology) (HAA; IQ >/= 70) and childhood autism (HCA), 53 HAA children (mean: 6.0 +/- 0.5 years) were compared with 21 HCA children (mean: 8.2 +/- 1.1 years) on the Childhood Autism Rating Scale-Tokyo version (CARS-TV). Because IQ on the Japanese version of the Stanford-Binet and CARS-TV total scores differed significantly between HAA and HCA, analysis of covariance was conducted with IQ and CARS-TV total scores controlled for. In two items of CARS-TV (relationship with people and general impressions) the HAA children were significantly less abnormal than the HCA children. Affect tended to be significantly milder in HAA than HCA. Anxiety reaction was significantly more abnormal in HAA than HCA. These findings may be useful to distinguish between HAA and HCA.

Changes in the structure of managed red pine forests in Wisconsin caused by interacting root- and stem-colonizing insects are associated with increased abundance of the blacklegged tick, Ixodes scapularis Say, in comparison with nonimpacted stands. However, the frequency and variability of the occurrence of tick-borne pathogens in this coniferous forest type across Wisconsin is unknown. Red pine forests were surveyed from 2009 to 2013 to determine the prevalence of Borrelia burgdorferi and Anaplasma phagocytophilum in questing I. scapularis nymphs. Polymerase chain reaction analysis revealed geographical differences in the nymphal infection prevalence (NIP) of these pathogens in red pine forests. In the Kettle Moraine State Forest (KMSF) in southeastern Wisconsin, NIP of B. burgdorferi across all years was 35% (range of 14.5-53.0%). At the Black River State Forest (BRSF) in western Wisconsin, NIP of B. burgdorferi across all years was 26% (range of 10.9-35.5%). Differences in NIP of B. burgdorferi between KMSF and BRSF were statistically significant for 2010 and 2011 and for all years combined (P < 0.05). NIP ofA. phagocytophilum (human agent) averaged 9% (range of 4.6-15.8%) at KMSF and 3% (range of 0-6.4%) at BRSF, and was significantly different between the sites for all years combined (P < 0.05). Differences in coinfection of B. burgdorferi and A. phagocytophilum were not statistically significant between KMSF and BRSF, with an average of 3.4% (range of 1.7-10.5%) and 2.5% (range of 0-5.5%), respectively. In 2013, the density of infected nymphs in KMSF and BRSF was 14 and 30 per 1000m2, respectively, among the highest ever recorded for the state. Differences in the density of nymphs and NIP among sites were neither correlated with environmental factors nor time since tick colonization. These results document significant unexplained variation in tick-borne pathogens between coniferous forests in Wisconsin that warrants further study.

Background There is a general concern that aged organs are more susceptible to ischaemia. In the light of recent proposals to change the liver allocation system by expanding regional sharing, it is feared that increased cold ischaemia time of grafts from older donors may reduce graft survival. The aim of this study was to correlate donor age and the patterns of ischaemia reperfusion injury and synthetic function early after liver transplantation. Methods We performed a retrospective study of first transplants using a single-centre electronic database. Patterns of liver injury (based on transaminases and post-reperfusion biopsy), synthetic function (international normalized ratio [INR]), and graft and patient survival in recipients receiving liver grafts from donors aged ≥65 years (group 1, n= 50) were compared with equivalent patterns in a matched cohort of recipients transplanted with grafts from donors aged <65 years (group 2, n= 50). Results There was no significant difference in transaminase levels from day 0 to day 6 after transplantation. When groups 1 and 2 were subdivided into two subgroups based on the duration of graft cold ischaemia time (<8 h and ≥8 h), there was no statistical difference in transaminase levels during the first 7 days. There were two cases (4%) of primary non-function in group 1 and one (2%) in group 2. Initial poor function did not differ significantly between the groups (26% vs. 24%; P= 0.81). In addition, there was no difference in histological changes in post-reperfusion biopsies (21% vs. 34%; P= 0.078) and rate of acute rejection episodes in the first year (30% vs. 32%; P= 0.99). There was no significant difference between groups 1 and 2 in 1-year patient and graft survivals (78% vs. 90% [P= 0.17]; 88% vs. 94% [P= 0.48], respectively). Conclusions Judiciously selected livers from aged donors are not associated with major increased susceptibility to ischaemia reperfusion injury. PMID:21309940
Self-perception of the antecedents of loneliness among new mothers and pregnant women.
Rokach, Ami
2007-02-01
This study examined the perceived causes of loneliness of pregnant women and mothers during the first year after childbirth experience. These were compared with the causes of loneliness of women in the general population. 91 pregnant women, 97 women during the first year following childbirth, and 208 women from the general population (M age = 30.4, SD = 10.4) answered a 29-item Loneliness Antecedents Questionnaire. In the questionnaire were 5 dimensions of sources of loneliness, namely, Personal Inadequacies, Developmental Deficits, Unfulfilling Intimate Relationships, Relocation/Significant Separation, and Social Marginality. Sources of loneliness were significantly different amongst the three groups. The differences were confined to the Personal Inadequacies, and the Relocation/Significant Separation subscales. In both, women from the general population had the highest mean subscale scores.

Obese patients have greater comorbidities along with higher risk of complications and greater costs after spine surgery, which may result in increased cost and lower quality of life compared with their non-obese counterparts. The aim of the present study was to determine cost-utility following anterior cervical discectomy and fusion (ACDF) in obese patients. This study analyzed prospectively collected data. Patients undergoing elective ACDF for degenerative cervical pathology at a single academic institution were included in the study. Cost and quality-adjusted life years (QALYs) were the outcome measures. One- and two-year medical resource utilization, missed work, and health state values (QALYs) were assessed. Two-year resource use was multiplied by unit costs based on Medicare national payment amounts (direct cost). Patient and caregiver workday losses were multiplied by the self-reported gross-of-tax wage rate (indirect cost). Total cost (direct+indirect) was used to compute cost per QALY gained. Patients were defined as obese for body mass index (BMI) ≥35 based on the WHO definition of class II obesity. A subgroup analysis was conducted in morbidly obese patients (BMI≥40). There were significant improvements in pain (neck pain or arm pain), disability (Neck Disability Index), and quality of life (EuroQol-5D and Short Form-12) at 2 years after surgery (p<.001). There was no significant difference in post-discharge health-care resource utilization, direct cost, indirect cost, and total cost between obese and non-obese patients at postoperative 1-year and 2-year follow-up. Mean 2-year direct cost for obese patients was $19,225±$8,065 and $17,635±$6,413 for non-obese patients (p=.14). There was no significant difference in the mean total 2-year cost between obese ($23,144±$9,216) and non-obese ($22,183±$10,564) patients (p=.48). Obese patients had a lower mean cumulative gain in QALYs versus non-obese patients at 2-years (0.34 vs. 0.42, p=.32). Two-year cost-utility in obese ($68,070/QALY) versus non-obese patients ($52,816/QALY) was not significantly different (p=.11). Morbidly obese patients had lower QALYs gained (0.17) and higher cost per QALYs gained ($138,094/QALY) at 2 years. Anterior cervical discectomy and fusion provided a significant gain in health state utility in obese patients, with a mean 2-year cost-utility of $68,070 per QALYs gained, which can be considered moderately cost-effective. Morbidly obese patients had lower cost-effectiveness; however, surgery does provide a significant improvement in outcomes. Obesity, and specifically morbid obesity, should to be taken into consideration as physician and hospital reimbursements move toward a bundled model. Copyright © 2016 Elsevier Inc.

An enhancement programme based on stocking 0+ year age-class Atlantic salmon Salmo salar, conducted in the River Bush, Northern Ireland, U.K. over the period 1996-2005, was reviewed with reference to the performance and biological characteristics of wild fish. Wild ova to 0+ year fry (summer) survival was c. 8% with subsequent wild 0+ year fry-to-smolt survival c. 9%. Stocked unfed 0+ year juveniles gave c. 1% survival to smolt whilst fed 0+ year S. salar stocked in late summer exhibited survival at c. 5%. Stocking with unfed and fed fry contributed to increased smolt production and helped attain local management objectives between 2001 and 2005. Significant differences in biological characteristics were observed between wild and stocked-origin fish. Wild-smolt cohorts were dominated by 2+ year age-class fish on the River Bush whilst smolts originating from fed fry mostly comprised younger 1+ year individuals. The mean mass of 1+ year smolts derived from stocked fed fry was significantly lower than that of wild 1+ year smolts, although these differences were not evident between older age classes. Differences in run timing between wild smolts and smolts derived from stocked fry were also apparent with the stocked-origin fish tending to run earlier than wild fish. Although the stocking exercise was useful in terms of maximizing freshwater production, concerns over the quality of stocked-origin recruits and the long term consequences for productivity are highlighted. © 2012 The Authors.

It is unknown whether the height of a heel-rise performed in the single-leg standing heel-rise test 1 year after an Achilles tendon rupture (ATR) correlates with ankle biomechanics during walking, jogging, and jumping in the long-term. To explore the differences in ankle biomechanics, tendon length, calf muscle recovery, and patient-reported outcomes at a mean of 6 years after ATR between 2 groups that, at 1-year follow-up, had less than 15% versus greater than 30% differences in heel-rise height. Cohort study; Level of evidence, 3. Seventeen patients with less than 15% (<15% group) and 17 patients with greater than 30% (>30% group) side-to-side difference in heel-rise height at 1 year after ATR were evaluated at a mean (SD) 6.1 (2.0) years after their ATR. Ankle kinematics and kinetics were sampled via standard motion capture procedures during walking, jogging, and jumping. Patient-reported outcome was evaluated with Achilles tendon Total Rupture Score (ATRS), Physical Activity Scale (PAS), and Foot and Ankle Outcome Score (FAOS). Tendon length was evaluated by ultrasonography. The Limb Symmetry Index (LSI = [Injured Side ÷ Healthy Side] × 100) was calculated for side differences. The >30% group had significantly more deficits in ankle kinetics during all activities compared with patients in the <15% group at a mean of 6 years after ATR (LSI, 70%-149% and 84%-106%, respectively; P = .010-.024). The >30% group, compared with the <15% group, also had significantly lower values in heel-rise height (LSI, 72% and 95%, respectively; P < .001) and heel-rise work (LSI, 58% and 91%, respectively; P < .001) and significantly larger side-to-side difference in tendon length (114% and 106%, respectively; P = .012). Achilles tendon length correlated with ankle kinematic variables ( r = 0.38-0.44; P = .015-.027) whereas heel-rise work correlated with kinetic variables ( r = -0.57 to 0.56; P = .001-.047). LSI tendon length correlated negatively with LSI heel-rise height ( r = -0.41; P = .018). No differences were found between groups in patient-reported outcome ( P = .143-.852). Height obtained during the single-leg standing heel-rise test performed 1 year after ATR related to the long-term ability to regain normal ankle biomechanics. Minimizing tendon elongation and regaining heel-rise height may be important for the long-term recovery of ankle biomechanics, particularly during more demanding activities such as jumping.

The objectives of this study are to compare the prevalence of MIH in children seeking dental care spontaneously at the Department of Comprehensive Children's Dentistry of the University of Buenos Aires (UBA) and Department of Pediatric Dentistry of the University of La República (UdelaR) and to analyze the distribution according to year of birth, sex, age, number of affected teeth and maximum degree of severity in molars and incisors. During 2010, nine pediatric dentists from both schools (Kappa = 0.94) assessed all children born between 1993 and 2003 whose 4 first molars and 8 permanent incisors had erupted. Specially designed charts were used to record sex, year of birth, institution, presence of MIH, number of affected incisors and molars and maximum degree of severity for each tooth. Two groups were formed: UBA: A (n = 512) and UdelaR: B (n = 463). 975 children (11.6 +/- 2.67 years) were evaluated. The prevalence of MIH in the total sample was 6.56%, without significant differences between A and B (p = 0.76). There was no significant difference between groups regarding age (p = 0. 95) or sex (p = 0.30). A significant increase was found in both institutions according to year of birth during the study period. (A: p = 0.0017) B: p = 0. 0058). The results of this study show a similar prevalence of MIH among patients seeking dental care at the Schools of Dentistry of the University of Buenos Aires (Argentina) and University of la República (Uruguay). No significant difference was found comparing the distribution by sex, affected teeth or severity of each tooth. A highly significant positive correlation was found regarding the year of birth. The relevance of MIH as an emerging pathology requires studies on larger samples covering the entire countries.

The purpose of the study was to compare the level of energy expenditure due to physical activity (EEPA) and functional fitness (FF) in 59 women and 82 men aged 70-80 years, divided into three groups: permanent residents in assisted-living facilities (ALFs), participants in adult day care centers (DCCs) and older people living independently, members in community senior centers (CSCs). EEPA and FF were analyzed taking into consideration sex differences. The energy expenditure tended to be lower in DCCs and ALFs subjects than in CSCs members, but significant differences were obtained only in women. Women in different living settings differed only in endurance. In men, the differences were clear in most tests (endurance, strength, agility/dynamic balance) except for flexibility. Institutionalization was connected with a significantly lower level of FF and equalization of sex differences. Education seemed to be an important factor influencing the level of FF in men.

To assess age- and site-related bone mineral density (BMD) values in Korean female patients with a distal radius fracture, and to compare them with those of the community-based general Korean female population. For this study, we recruited 54 consecutive Korean women, 50 to 79 years of age, with a distal radius fracture caused by minor trauma. We performed dual-energy x-ray absorptiometry scans at central sites: the lumbar spine, femoral neck, trochanter, and Ward's triangle, which is a triangular area within the femoral neck. Age- and site-related BMDs were assessed and compared with those of population-based reference data for Korean women. The overall prevalence (defined as meeting the osteoporosis criteria in at least one of the earlier-described measurement areas) of osteoporosis in patients with a distal radius fracture was 57%. The site-related prevalence was 54% at Ward's triangle, 43% at the lumbar spine, 32% at the femoral neck, and 26% at the trochanter, and these values were individually statistically significantly higher than those of the general Korean female population except for the lumbar spine. In patients 50 to 59 and 70 to 79 years of age, patients' mean BMD values at the hip were statistically significantly lower than those of the reference female population of corresponding age groups, but the hip BMD differences were not statistically significant in patients 60 to 69 years of age. There were no statistically significant BMD differences measured at the lumbar spine in any age group. Korean female patients with a distal radius fracture, 50 to 59 and 70 to 79 years of age, had lower BMDs at the hip than the reference Korean female population. However, no statistically significant BMD differences were found in those 60 to 69 years of age. Low BMD may have a greater impact on distal radius fracture in women younger than 60 years of age or over 70 years of age. Considering the young onset of bone loss, patients younger than 60 years of age with a distal radius fracture are a good target group for secondary prevention of osteoporosis.

Objective To determine whether the long-term visual outcome of small incision lenticule extraction (SMILE) surgery is consistent with the short-term results in high myopic eyes. Design Retrospective cohort study; data collected from 8 August 2011 to 31 August 2015. Setting Single refractive surgery centre. Participants A total of 156 eyes were studied: 65 eyes of 39 subjects (22 female/17 male) in the high myopic group (manifest refraction spherical equivalent (MRSE) ≥−6.0 D), and 91 eyes of 54 subjects (29 female/25 male) in the control group (MRSE <−6.0 D). The inclusion criteria were subjects who had follow-ups after 1 day, 1 week, 1 month, 3, 6 months and 1 year with the manifest refraction, uncorrected and corrected distance visual acuity (UDVA/CDVA). There were no statistically significant differences between the two groups in the subjects' gender, age, or cylindrical dioptre, preoperatively (p=0.835, p=0.055, p=0.341, respectively). Primary and secondary outcome measures UDVA, refractive stability, safety index (postoperative CDVA/preoperative CDVA), and predictability (the percentage of eyes within ±0.50 D). Results In both groups, the 1-year UDVA and safety index were significantly better than results at 1 day (high myopic group: p=0.035, p<0.001; control group: p<0.016, p<0.001); the 1-year predictability showed no significant difference with the short-term results (p=1.00 in both groups). In the high myopic eyes, the 1-year MRSE was significantly worse than the short-term result (p=0.048). To correct it, the added magnitude (D) for the high myopic eyes may equal 0.13×Attempted SE (D)−0.66 D. However, the postoperative MRSE showed no differences from 1 day to 1 year (p=0.612) in the control group. Conclusions The 1-year visual outcomes were better than the short-term results after the SMILE surgery on the visual acuity and safety. However, the high myopic eyes suffered a significant regression at 1 year, which may be corrected by adding additional magnitude to the SE for high myopic eyes. PMID:27655258

To evaluate self-reported oral health attitudes and behavior among a group of dental students in Bangalore, India and to compare the oral health attitudes of students of different years of dental school. A self-administered questionnaire based on a modified version of the Hiroshima University Dental Behavior Inventory (HU-DBI) was administered to 250 dental students. Significant differences (P<.05) were observed among students of different years in the degree of worrying about the color of the teeth, not having been to the dentist before and brushing each tooth carefully. Strongly significant differences (P<.001) were observed among students of different years in brushing the teeth twice daily, being satisfied with the appearance of the teeth, cleaning the teeth well without toothpaste, visiting dentist only when having a toothache, taking too much time to brush their teeth, worrying about having bad breath and using mouth rinse on a regular basis. Among dental students, the overall knowledge of oral health was good, even though there were deficits in knowledge in a few areas. The oral health attitudes and behavior of dental students improved with increasing levels of education.

Objective. To examine racial differences in communication apprehension and interprofessional socialization in fourth-year PharmD students and to investigate the relationship between the two constructs. Methods. Two measures with reliability and validity psychometric evidence were administered to fourth-year pharmacy students at a single historically black university with a large racial minority population. The Personal Report of Communication Apprehension (PRCA-24) measures level of fear or anxiety associated with communication. The Interprofessional Socialization and Valuing Scale (ISVS) measures beliefs, attitudes, and behaviors towards interprofessional collaborative practice. Results. One hundred fourteen students completed the survey. This produced a 77.4% response rate and 45.6% of the participants were African American. There were significant differences between races (ie, White, African-American, and Asian) on both measures. The PCRA-24 and ISVS were significantly correlated in each racial group. Conclusion. As pharmacy education moves to more interprofessional collaborations, the racial differences need to be considered and further explored. Pharmacy curricula can be structured to promote students’ comfort when communicating interprofessionally across racial groups. Understanding of culture and early education in cultural competence may need to be emphasized to navigate racial or cultural differences. PMID:26941434

Considerable studies have addressed effects of age and sex on voice onset time (VOT) in English. However, few studies have examined these effects on Mandarin stops. This study attempts to examine effects of age and sex on VOT in Mandarin. A total of 85 Mandarin-speaking children, aged 4-18 years old, and 13 adults as reference participated in a production experiment. Productions were elicited by reading target words in carrier phrases. Results showed that children aged 6-7 years old had longer VOTs than older ones for highly aspirated stops, and the same tendency was not observed for unaspirated stops. However, no linear developmental trend was observed for both highly aspirated and unaspirated stops. In addition, females displayed longer VOTs for highly aspirated stops and shorter for unaspirated stops, whereas significant sex differences in VOTs existed from 14 years old to adulthood for highly aspirated stops, and no significant sex differences in VOTs were found for unaspirated stops in each group, indicating that sex differences in VOTs varied with age and aspiration. The findings suggest that physiological changes in and differences between males and females provide account for some, but not all differences in VOTs across age and sex.

The aim of this study was to investigate possible effects that participation in sports, exercise, and recreation may have on self-esteem and quality-of-life in service members/veterans with disabilities. Two hundred twenty service members/veterans with disabilities who were participants in one of three annual adaptive sporting events took part in this cross-sectional study. Variables of interest were years of sport, exercise, and recreation participation since the onset of disability as well as the type of activity they engaged in. Main outcome measures were self-esteem and quality-of-life. A positive relationship was found between participant quality-of-life and the number of years spent participating in sports, exercise, and recreation since the onset of their disability. A significant difference was found between pre-event and postevent self-esteem scores. A significant difference was also found in self-esteem scores between the levels of years of participation in sports, exercise, and recreation when averaged across activity type. Finally, there were significant differences found on self-esteem scores between the levels of type of activity averaged across years of participation. Our results indicate that participation in sports, exercise, and recreation has a positive influence on self-esteem and quality-of-life in individuals with disabilities.

Educational attainment and gender differences on fluid intelligence (Gf), crystallized intelligence (Gc), and academic skills in reading, math, and writing were analyzed for stratified adult samples ranging in age from 22 to 90 years. The data sources were the adult portions of the standardization samples of the second editions of Kaufman Brief Intelligence Test (N = 570) and the Kaufman Test of Educational Achievement-Brief Form (N = 555). Five univariate analysis of covariance were conducted with age as the covariate. Correlational analysis supplemented the covariate analyses to better understand the relationship of the five variables to education. All variables related significantly and substantially to years of formal schooling, an important finding in view of the key nature of this background variable for conducting neuropsychological assessments, as elaborated by Heaton and his colleagues. Surprisingly, Gf related just as strongly to education as did the school-related Gc. Among academic skill areas, math correlated higher with years of formal schooling than did either reading or writing. Women significantly outperformed men on the writing test and the reverse was true for the math test; other gender differences were not significant. These analyses fill a gap in the literature regarding the nature of gender and education differences in academic skills for heterogeneous samples of normal adults between young adulthood and old age and have practical implications for neuropsychological assessment.

To evaluate the psychosexual benefit obtained from multicomponent penile implant surgery in patients with erectile dysfunction. A psychosexual questionnaire was given to 35 patients undergoing penile prosthesis implantation before surgery and at 3 months, 6 months, and 1 year after surgery. The questionnaire consisted of 13 questions scored on a scale from 1 through 5. Results of the questionnaire were statistically analyzed for differences among the preoperative, 3-month postoperative, 6-month postoperative, and 1-year postoperative period. The general linear model evaluation showed a significant difference for each overall combination of the following pairs: preoperative versus 3 months postoperative (P=0.0005) and 3 months postoperative versus 6 months postoperative (P=0.002). There was no overall difference between psychosexual total score at 6 months after surgery and 1 year after prosthesis implantation (P=0.85). The patients perceived improvement in their erectile ability and libido. Concern about obtaining and maintaining an erection during intercourse was significantly alleviated. There was an increase in the frequency of sexual activity and an improvement in satisfaction with sex life. A decrease in feelings of sadness, depression, anxiety, anger, frustration, and embarrassment related to sexual activity was also noted. The current study demonstrates significant improvement in the psychosexual well being of multicomponent penile implant recipients, with attainment of a high level of patient satisfaction up to 1 year after surgery.

2014-07-01
In order to understand the accumulation dynamic of triterpenoid saponins in Akebia trifoliata stem to determine the suitable harvesting time and the growth age of stem. The contents of effective components, oleanolic acid and hederagenin in Akebia trifoliata stems, collected at the same growth condition of different growth ages and different harvesting time, were compared by high performance liquid chromatography (HPLC). The accumulation period of oleanolic acid was from the first year to the sixth year, the content rose quickly in the seventh year, and reached the greatest at the ninth year, then declined quickly, the contents in stem of more than 10 years had no significant difference compared with that of 1 - 6 years. The content of herderagenin had no great change by the age of stem. Comprehensive consideration,the triterpenoid saponins contents of the eight to nine years old Akebia trifoliata stems were higher. The most appropriate harvesting time for Akebia trifoliata was from later August to later September in the eighth years.

Twenty-two Golden Eagle (Aquila chrysaetos) nesting territories and 31 occupied eagle nests were documented on the north slope of the Brooks Range in northeastern Alaska, 1988-1990, in an area previously thought to be marginal breeding habitat for eagles. The mean number of young/successful nest was 1.25 in 1988, 1.27 in 1989, and 1.13 in 1990; means did not differ significantly among years. Eighty percent (20/25) of the nestlings for which age was estimated were assumed to have successfully fledged. Nesting success was 79% (11/14) in 1989, the only year nesting success could be determined. Laying dates ranged from 23 March (1990) to 11 May (1989) with mean estimated laying dates differing significantly among years. Annual variation in nesting phenology coincided with annual differences in snow accumulations during spring. These results indicate that Golden Eagles consistently and successfully breed at the northern extent of their range in Alaska, although, productivity may be lower than that for eagles at more southern latitudes.
Child witnesses' metamemory realism.

This study investigated the degree of realism in the confidence judgments of 11 to 12-year-olds (41 girls and 40 boys) of their answers to questions relating to a short film clip showing a kidnapping event. Four different confidence scales were used: a numeric scale, a picture scale, a line scale and a written scale. The results demonstrated that the children showed a high level of overconfidence in their memories. However, no significant differences between the four confidence scales were found. Weak gender differences were found in that the girls were slightly, but significantly, better calibrated than the boys. In addition, although both boys and girls overestimated the total number of memory questions they had answered correctly, the boys gave higher estimates compared with the girls. In brief, the results indicate that, at least in the context investigated, 11-12 year-old children's confidence in and estimations of their own event memory show poor realism (overconfidence and overestimation). A comparison with previous research on adults indicates that 11 to 12-year-old children show noticeably poorer realism.

Obesity and a reduced physical activity are global developments. Physical activity affects the external skeletal robustness which decreased in German children. It was assumed that the negative trend of decreased external skeletal robustness can be found in other countries. Therefore anthropometric data of Russian and German children from the years 2000 and 2010 were compared. Russian (2000/2010 n = 1023/268) and German (2000/2010 n = 2103/1750) children aged 6-10 years were investigated. Height, BMI and external skeletal robustness (Frame-Index) were examined and compared for the years and the countries. Statistical analysis was performed by Mann-Whitney-Test. Comparison 2010 and 2000: In Russian children BMI was significantly higher; boys were significantly taller and exhibited a decreased Frame-Index (p = .002) in 2010. German boys showed significantly higher BMI in 2010. In both sexes Frame-Index (p = .001) was reduced in 2010. Comparison Russian and German children in 2000: BMI, height and Frame-Index were different between Russian and German children. German children were significantly taller but exhibited a lower Frame-Index (p<.001). Even German girls showed a significantly higher BMI. Comparison Russian and German children in 2010: BMI and Frame-Index were different. Russian children displayed a higher Frame-Index (p<.001) compared with Germans. In Russian children BMI has increased in recent years. Frame-Index is still higher in Russian children compared with Germans however in Russian boys Frame-Index is reduced. This trend and the physical activity should be observed in the future.

A multicentre cohort study was held in Morocco, designed to evaluate the quality of life of cancer patients. The aim of this paper is to report the assessment of the quality of life of early colorectal cancer patients, before and after cancer treatment, to identify other factors which are related to this quality of life. We used the third version of the QLQ-C30 questionnaire of the European organization for Research and treatment of Cancer (EORTC) after a transcultural validation. The Data collection was done at inclusion and then every twelve weeks to achieve one year of follow up. Overall 294 patients presented with early colorectal cancer, the median age was 56 years (range: 21-88). The male-female sex ratio was 1.17. At inclusion, the global health status was the most affected functional dimension. For symptoms: financial difficulties and fatigue scores were the highest ones. Emotional and social functions were significantly worse in rectal cancer. Most symptoms were more present in rectal cancer. At inclusion, global health status score was significantly worse in stage III. Anorexia was significantly more important among colorectal female patients. For Patients over 70 years-old, the difference was statistically significant for the physical function item which was lower. Overall, Functional dimensions scores were improved after chemotherapy. The symptoms scores did not differ significantly for patients treated by radiotherapy, between inclusion and at one year. Our EORTC QLQ C30 scores are overall comparable to the reference values. Neither chemotherapy, nor radiotherapy worsened the quality of life at one year.

An acute infection after arthroscopic shoulder surgery is a rare but serious complication. Previous studies estimating the incidence of infections after arthroscopic surgery have been conducted, but the majority of these had either relatively small study groups or were not specific to shoulder arthroscopic surgery. To investigate the incidence of acute infections after arthroscopic shoulder surgery and compare infection rates by age group, sex, geographic region, and specific procedures. Case series; Level of evidence, 4. A retrospective review of a large insurance company database was performed for all shoulder arthroscopic surgeries performed in the United States between 2004 and 2009 that required additional surgery for infections within 30 days. The data were stratified by sex, age group, and region. Data were also stratified for specific procedures (capsulorrhaphy, treatment for superior labrum anterior-posterior tears, claviculectomy, decompression, and rotator cuff repair) and used to assess the variation in the incidence of infections across different arthroscopic shoulder procedures. Linear regression was used to determine the significance of differences in the data from year to year. χ(2) analysis was used to assess the statistical significance of variations among all groups. Poisson regression analysis with exposure was used to determine significant differences in a pairwise comparison between 2 groups. The total number of arthroscopic shoulder surgeries performed was 165,820, and the number of infections requiring additional surgery was 450, resulting in an overall infection rate of 0.27%. The incidence of infections varied significantly across age groups (P < .001); the infection rate was highest in the ≥60-year age group (0.36%) and lowest in the 10- to 39-year age group (0.18%). The incidence of infections also varied by region (P < .001); the incidence was highest in the South (0.37%) and lowest in the Midwest (0.11%). The incidence of infection treatments was also significantly different between different arthroscopic procedures (P < .01) and was highest for rotator cuff repair (0.29%) and lowest for capsulorrhaphy (0.16%). The incidence did not significantly vary by year or sex. The overall infection rate for all arthroscopic shoulder procedures was 0.27%. The incidence was highest in elderly patients, in the South, and for rotator cuff repair. The incidence was lowest in young patients, in the Midwest, and for capsulorrhaphy. In general, shoulder arthroscopic surgery in this study population had a low rate of reoperation in the acute period.

To investigate personality traits in patients with Alzheimer disease, compared with mentally healthy control subjects. We compared both current personality characteristics using structured interviews as well as current and previous personality traits as assessed by proxies. Fifty-four patients with mild Alzheimer disease and 64 control subjects described their personality traits using the Structured Interview for the Five-Factor Model. Family members filled in the Revised NEO Personality Inventory, Form R, to evaluate their proxies' current personality traits, compared with 5 years before the estimated beginning of Alzheimer disease or 5 years before the control subjects. After controlling for age, the Alzheimer disease group presented significantly higher scores than normal control subjects on current neuroticism, and significantly lower scores on current extraversion, openness, and conscientiousness, while no significant difference was observed on agreeableness. A similar profile, though less accentuated, was observed when considering personality traits as the patients' proxies remembered them. Diachronic personality assessment showed again significant differences between the 2 groups for the same 4 domains, with important personality changes only for the Alzheimer disease group. Group comparison and retrospective personality evaluation are convergent. Significant personality changes follow a specific trend in patients with Alzheimer disease and contrast with the stability generally observed in mentally healthy people in their personality profile throughout their lives. Whether or not the personality assessment 5 years before the current status corresponds to an early sign of Alzheimer disease or real premorbid personality differences in people who later develop Alzheimer disease requires longitudinal studies.

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

The flood hazard for the California coast depends not only on the magnitude, location, and rupture length of Alaska-Aleutian subduction zone earthquakes and their resultant tsunamis, but also on rising sea levels, which combine with tsunamis to produce overall flood levels. The magnitude of future sea-level rise remains uncertain even on the decadal scale, with future sea-level projections becoming even more uncertain at timeframes of a century or more. Earthquake statistics indicate that timeframes of ten thousand to one hundred thousand years are needed to capture rare, very large earthquakes. Because of the different timescales between reliable sea-level projections and earthquake distributions, simply combining the different probabilities in the context of a tsunami hazard assessment may be flawed. Here, we considered 15 earthquakes between Mw 8 to Mw 9.4 bound by -171oW and -140oW of the Alaska-Aleutian subduction zone. We employed 24 realizations at each magnitude with random epicenter locations and different fault length-to-width ratios, and simulated the tsunami evolution from these 360 earthquakes at each decade from the years 2000 to 2200. These simulations were then carried out for different sea-level-rise projections to analyze the future flood hazard for California. Looking at the flood levels at tide gauges, we found that the flood level simulated at, for example, the year 2100 (including respective sea-level change) is different from the flood level calculated by adding the flood for the year 2000 to the sea-level change prediction for the year 2100. This is consistent for all sea-level rise scenarios, and this difference in flood levels range between 5% and 12% for the larger half of the given magnitude interval. Focusing on flood levels at the tide gauge in the Port of Los Angeles, the most probable flood level (including all earthquake magnitudes) in the year 2000 was 5 cm. Depending on the sea-level predictions, in the year 2050 the most probable flood levels could rise to 20 to 30 cm, but increase significantly from 2100 to 2200 to between 0.5 m and 2.5 m. Aside from the significant increase in flood level, it should be noted that the range over which potential most probable flood levels can vary is significant and defines a tremendous challenge for long-term planning of hazard mitigating measures.

A re-pneumatization phenomenon was recorded in sinuses grafted with different materials. The specific aims of this paper were to assess the dental implant survival rate and the behavior of marginal and apical bone remodeling around dental implants placed following sinus augmentation. A retrospective study was conducted on consecutive patients treated in two surgical centers. Different surgical techniques were adopted for sinus augmentation: simultaneous or delayed dental implant insertion with bovine bone-material augmentation or autologous bone grafting (chin and iliac crest). Survival rates were recorded for the overall number of implants (patients of group A). Apical and marginal bone levels (ABL and MBL, respectively) were radiographically measured, and statistical analysis was performed in implants of a subgroup of patients (group B). A total of 282 dental implants were positioned. Recorded cumulative survival rates (CSRs) were 95.6% and 100% for autogenous and bovine bone material, respectively, while CSRs at 2-year follow-up for immediate and delayed procedures were 99.3% and 96.5%. For the subgroup B, 57 sinus augmentation procedures were performed in 39 patients, with the positioning of 154 implants. Generally, the apical- and marginal-bone resorption of the bovine bone-material group was less than that of the autogenous group. The differences between the ABL values of the bovine bone-material and iliac-crest groups were statistically significant at 1 year, whereas this significance disappeared at the 2-year follow-up; tests showed that a statistical difference was recorded in the bovine bone-material group between the 1- and 2-year follow-ups. With regard to MBL comparisons between simultaneous and delayed implantation, the differences maintained their significance at the 2-year follow-up also. Differences regarding apical bone alteration between autogenous bone from the iliac crest and bovine bone material at the 1- and 2-year follow-ups, as well as in the bovine bone-material group between the 1- and 2-year follow-ups, attested to slower but more prolonged physiologic bone remodeling in the bovine-graft-material group than in the autogenous-bone group. The MBL analysis showed that remodeling in the delayed implant group demonstrated a greater resorption in the cervical portion than was seen in the simultaneous implant group. © 2010 John Wiley & Sons A/S.

To test whether cross-sectional or longitudinal measures of thigh muscle isometric strength differ between knees with and without subsequent radiographic progression of knee osteoarthritis (KOA), with particular focus on pre-osteoarthritic female knees (knees with risk factors but without definite radiographic KOA). Of 4,796 Osteoarthritis Initiative participants, 2,835 knees with Kellgren Lawrence grade (KLG) 0-3 had central X-ray readings, annual quantitative joint space width (JSW) and isometric muscle strength measurements (Good strength chair). Separate slope analysis of covariance (ANCOVA) models were used to determine differences in strength between "progressor" and "non-progressor" knees, after adjusting for age, body mass index, and pain. 466 participant knees exceeded the smallest detectable JSW change during each of two observation intervals (year 2→4 and year 1→3) and were classified as progressors (213 women, 253 men; 128 KLG0/1, 330 KLG2/3); 946 participant knees did not exceed this threshold in either interval and were classified as non-progressors (588 women, 358 from men; 288KLG0/1, 658KLG2/3). Female progressor knees, including those with KLG0/1, tended to have lower extensor and flexor strength at year 2 and at baseline than those without progression, but the difference was not significant after adjusting for confounders. No significant difference was observed in longitudinal change of muscle strength (baseline→year 2) prior to radiographic progression. No significant differences were found for muscle strength in men, and none for change in strength concomitant with progression. This study provides no strong evidence that (changes in) isometric muscle strength precedes or is associated with structural (radiographic) progression of KOA.

Objective Home oximetry is commonly used to screen for obstructive sleep apnea (OSA) in children; however, normal oxygen desaturation levels by disease severity are not well known. It was our objective to determine if oxygen saturation levels differed by OSA severity category in children and if these differences were similar for preteen children and adolescents. Study Design Retrospective case series of children undergoing polysomnography from September 2011 to July 2015. Setting Tertiary pediatric hospital. Subjects and Methods Six- to 18-year-olds (preteen, 6-12 years old; adolescent, 13-18 years old). Chi-square, Wilcoxon rank sum test, and Kruskal-Wallis testing were used to compare variables between age groups. Results The study included 342 children with a mean age of 11.3 ± 2.4 years (range, 6.5-17.5) and a mean body mass index of 25.6 ± 9.2 kg/m 2 (78 ± 29 percentile); 61% were white, 35% were black, and 4% were other or unknown. Of the children, 48% were female, and this was not a significant difference between age groups ( P = .81). Overall, 50% of the children had no OSA, 32% mild, 10% moderate, and 8% severe. When compared with the younger children, the adolescents had a longer sleep time ( P = .014) and a higher mean obstructive apnea-hypopnea index (3.53 ± 5.1 vs 3.03 ± 6.1 events per hour, P = .02). The 3% and 4% oxygen desaturation indices were not significantly different between age groups when accounting for OSA severity. Conclusion Adolescents have longer sleep times and higher obstructive apnea-hypopnea indexes than preteens, but oxygen saturations and desaturation indices were similar. This supports current triage algorithms for children with OSA, as we found no significant age-based differences.

Application and consequences of hemodialysis treatment may differ between genders; focusing on these differences may be useful to optimize outcomes. Data from 1 999 648 hemodialysis sessions performed in 10 984 (3316 incident and 7668 prevalent) patients, treated in 55 centers of the European Clinical Database (EuCliD)-Turkey, were analyzed, and various demographic, clinical, biochemical, therapeutic and prognostic parameters were compared. There were 1905 male and 1411 female incident and 4339 male and 3329 female prevalent patients. For females, the mean age in incident (61.8 ± 14.9 years) and prevalent (58.3 ± 15.2 years) patients was higher than for males (60.2 ± 14.8 and 56.5 ± 14.9 years, respectively) (P < 0.001 for both analyses). Also, body mass index was higher, while the hemoglobin level, and the percentage of interdialytic weight gain and arteriovenous fistula were lower. Serum phosphorus was similar in both genders in incident cases, while it was lower in prevalent female patients. Serum parathyroid hormone levels were lower in incident, but higher in prevalent male cases. Erythropoiesis-stimulating agents and vitamin D preparations were more frequently used in female incident and prevalent patients. Hospitalization was more frequent in prevalent females, while it did not differ significantly in the incident cases. Overall, no significant difference was observed in survival rates at 3 years in both incident and prevalent male and female patients. Many parameters differ significantly between female and male dialysis patients. Considering the effects of sex on several parameters may be a valuable approach for achieving better outcomes when formulating treatment strategies in this patient population.

Purpose The current study compared longitudinal relationships between college education and patterns of heavy drinking from early adolescence to adulthood for Caucasians and African Americans. Methods Data were collected from N=9,988 non-Hispanic Caucasian and African American participants from all four waves of the National Longitudinal Study of Adolescent Health. Growth curve modeling tested differences in rates of change and levels of heavy drinking from ages 13–31 among non-college youth, college withdrawers, 2-year-college graduates, and 4-year-college graduates, and compared these differences for Caucasians and African Americans. Results There were significant racial differences in relationships between college education with both changes in and levels of heavy drinking. Rates of change of heavy drinking differed significantly across the college education groups examined for Caucasians but not for African Americans. In addition, Caucasians who graduated from 4-year colleges showed the highest levels of heavy drinking after age 20, although differences between the four groups diminished by the early 30s. In contrast, for African Americans, graduates from 2- or 4-year colleges did not show higher levels of heavy drinking from ages 20–31 than the non-college group. Instead, African American participants who withdrew from college without an associate’s, bachelor’s, or professional degree consistently exhibited the highest levels of heavy drinking from ages 26–31. Conclusions The relationship between college education and increased levels of heavy drinking in young adulthood is significant for Caucasians but not African Americans. Conversely, African Americans are likely to be more adversely affected than Caucasians by college withdrawal. PMID:23707401

The purpose of this study was to determine the impact of a revised curriculum on medical student academic motivation, burnout, and quality of life. This cross-sectional comparative study involved 2 medical school cohorts of second year and fourth year medical students at The University of Auckland: a cohort under a traditional curriculum (n = 437) and a cohort under a revised curriculum (n = 446). Participants completed self-reported questionnaires measuring academic motivation, burnout, and quality of life. Two multivariate analyses of covariance (MANCOVAs) were conducted. The response rate was 48%. No statistically significant differences were found between curriculum cohorts for mean scores of academic motivation, personal burnout, and quality of life. However, differences were found when comparing preclinical medical students and students in their clinical years of training. In comparison with Year 2 medical students, the MANCOVA for Year 4 students showed a significant main effect for the revised curriculum with respect to both physical and environmental quality of life. A revised medical curriculum had a differential effect on quality of life for Year 4 students in the latter years of medical school who are based in a clinical learning environment.

Different hormones and peptides involved in lipid and carbohydrate metabolism have been studied in relation to morbid obesity and its variation after bariatric surgery. The aim of this study is toevaluate variations in different molecules related to glico-lipidic metabolism during the first year after sleeve gastrectomy in morbidly obese patients. Prospective study in patients undergoing sleeve gastrectomy between November 2009 and January 2011. We analyzed changes in different clinical, anthropometric and analytic parameters related with glico-lipidic metabolism in all patients in the preoperative period, first postoperative day, fifth day, one month, 6 months and one year after surgery. Statistical analysis was performed using SPSS 20.0. We included 20 patients, 60% were women with a median of age of 45 years. Median of body mass index (IMC) was 48,5 kg/m(2) and 70% had obstructive sleep apnea syndrome (SAOS), 65% arterial hypertension (HTA), 45% dyslipidemia and 40% diabetes mellitus. One year after surgery, the percentage of excess of BMI loss was 72% and the rate of cure or improvement of dyslipidemia was 100%, diabetes 87,5%, HTA 84,6% and SAOS 57,1%. At this time, glycemia levels decreased significantly (P<.001), and levels of IGF-1 and HDL-cholesterol increased significantly. Levels of adiponectine increased and leptine (P=.003), insulin (P=.004) and triglycerides (P=.016) decreased significantly one year after the surgery. ACTH levels (that decreased during first 6 months after surgery), glycosilated hemoglobin, total cholesterol and LDL-cholesterol had no changes one year after surgery. Sleeve gastrectomy is a surgical technique with good results of weight loss and cure of comorbidities. This procedure induces significant modifications in blood levels of glico-lipidic metabolism related peptides and hormones, such as glucose, IGF-1, insulin, leptin, triglycerides and HDL-cholesterol.

An earlier randomized controlled trial (RCT) study showed that bee venom acupuncture (BVA) in combination with physiotherapy can be more effective in functional improvement and pain reduction in patients with adhesive capsulitis (AC). The objective of the current study was to examine the long-term effect of BVA in combination with physiotherapy on AC of the shoulder. Retrospective 1-year follow-up analysis of a previous RCT using a telephone interview method. Outpatient joint center at the Gang Dong Kyung Hee University Hospital of Seoul, Republic of Korea. A total of 192 patients had been enrolled in the previous study, and 124 of these were excluded from the current study. Sixty-eight patients who had been treated with combined BVA and physiotherapy for AC of the shoulder for 2 months were interviewed at approximately 1 year after treatment by telephone. Sixty of 68 patients were included in the follow-up analysis. Twenty received BV 1 treatment (1:10,000 concentration BVA plus physiotherapy), 22 received BV 2 treatment (1:30,000 concentration BVA plus physiotherapy), and 18 received control treatment (normal saline injection plus physiotherapy). The primary outcome measure was Shoulder Pain And Disability Index (SPADI) score. Secondary outcome measure was score on verbal rating scale for pain and patient satisfaction. Baseline characteristics of the groups did not significantly differ. SPADI scores at 1 year significantly differed between the BV 1 group and the control group (p=0.043). No significant differences were found in pain verbal rating scores after 1 year. Treatment satisfaction with therapy was also assessed, and the BV 1 and BV 2 groups showed significantly greater satisfaction compared with the control group. BVA combined with physiotherapy remains clinically effective 1 year after treatment and may help improve long-term quality of life in patients with AC of the shoulder.

The Swedish-Norwegian Coldblooded trotter (CBT) is a local breed in Sweden and Norway mainly used for harness racing. Previous studies have shown that a mutation from cytosine (C) to adenine (A) in the doublesex and mab-3 related transcription factor 3 (DMRT3) gene has a major impact on harness racing performance of different breeds. An association of the DMRT3 mutation with early career performance has also been suggested. The aim of the current study was to investigate this proposed association in a randomly selected group of CBTs. 769 CBTs (485 raced, 284 unraced) were genotyped for the DMRT3 mutation. The association with racing performance was investigated for 13 performance traits and three different age intervals: 3 years, 3 to 6 years, and 7 to 10 years of age, using the statistical software R. Each performance trait was analyzed for association with DMRT3 using linear models. The results suggest no association of the DMRT3 mutation with precocity (i.e. performance at 3 years of age). Only two traits (race time and number of disqualifications) were significantly different between the genotypes, with AA horses having the fastest times and CC horses having the highest number of disqualifications at 3 years of age. The frequency of the AA genotype was significantly lower in the raced CBT sample compared with the unraced sample and less than 50% of the AA horses participated in a race. For the age intervals 3 to 6 and 7 to 10 years the AA horses also failed to demonstrate significantly better performance than the other genotypes. Although suggested as the most favorable genotype for racing performance in Standardbreds and Finnhorses across all ages, the AA genotype does not appear to be associated with superior performance, early or late, in the racing career of CBTs.

Early onset breast cancer is associated with poor outcomes but variable results have been reported. It is a significant problem in Pakistani women but remains under reported. Breast conservation plays an important role in surgical management of this younger patient group. The objective of this study was to determine the outcome of breast conservative therapy in patients with early onset breast cancer in our population and compare it with their older counterparts. A review of patients with invasive breast cancer who underwent breast conservation surgery at Shaukat Khanum Cancer Hospital from 1997 to 2009 was performed. Patients were divided into two groups i.e. Group I age ≤ 40 and Group II >40 years. A total of 401 patients with breast cancer were identified in Group I and 405 patients in Group II. Demographics, histopathological findings and receptor status of the two groups were compared. The Chi square test was used for categorical variables. Outcome was assessed on basis of 10 year locoregional recurrence free survival (LRRFS), disease free survival (DFS) and overall survival (OS) . For survival analysis Kaplan Meier curves were used and significance was determined using the Log rank test. Cox regression was applied for multivariate analysis. Median follow up was 4.31 (0.1-15.5) years. Median age at presentation was 34.6 years (17-40) and 51.9 years (41-82) for the two groups. Groups were significantly different from each other with respect to grade, receptor status, tumor stage and use of neoadjuvant therapy. No significant difference was present between the two groups for estimated 10 year LRRFS (86% vs 95%) (p=0.1), DFS (70% vs 70%) (p=0.5) and OS (75% vs 63%) (p=0.1). On multivariate analysis, tumor stage was an independent predictor of LRRFS, DFS and OS. Early onset breast cancer is associated with a distinct biology but does not lead to poorer outcomes in our population.

Deep brain stimulation for Parkinson's disease (PD) utilises an implantable pulse generator (IPG) whose finite lifespan in non-rechargeable systems necessitates their periodic replacement. We wish to determine if there is any significant difference in longevity of 2 commonly used IPG systems; the Medtronic Kinetra, and the Medtronic Activa Primary Cell (PC), which has come to replace it. All patients with bilateral Subthalamic Nucleus stimulators for PD performed in our centre were included. Battery life was then assessed using a Kaplan-Meier approach and comparisons between the Kinetra and Activa PC batteries were performed using log-rank tests. Complete data was available for 183 patients. There was a significant difference in the average battery duration with an estimated median battery life in the Kinetra cohort of 6.6 years (95% CI 6.4-6.7), compared to 4.5 years (95% CI 4.4-4.5) in the Activa PC cohort (p < 0.001). The Activa PC IPG demonstrates a significantly reduced battery life of 2.1 years, with a median battery life of 4.5 years in comparison to 6.6 years in the Kinetra IPG. Future technology developments should therefore be focused on improving the battery life of the newer IPG systems. © 2018 S. Karger AG, Basel.

The study of the change in the humus state of the fallow Luvisols of different ages under the influence of weeds and meadow vegetation was carried out in dynamics (after 5 years). It is shown that both under weedy and meadow vegetation there is a statistically significant accumulation of organic matter in the upper part of the long-arable horizon. Based on the study of composition and spectral properties of soil organic matter in fallow soils of different ages concluded that the significant qualitative change of the humus state of fallow soils requires significant time, measured at least decades.

Objectives: This study aimed to examine whether (a) exposure to universal newborn hearing screening (UNHS) and b) early confirmation of hearing loss were associated with benefits to expressive and receptive language outcomes in the teenage years for a cohort of spoken language users. It also aimed to determine whether either of these two variables was associated with benefits to relative language gain from middle childhood to adolescence within this cohort. Design: The participants were drawn from a prospective cohort study of a population sample of children with bilateral permanent childhood hearing loss, who varied in their exposure to UNHS and who had previously had their language skills assessed at 6–10 years. Sixty deaf or hard of hearing teenagers who were spoken language users and a comparison group of 38 teenagers with normal hearing completed standardized measures of their receptive and expressive language ability at 13–19 years. Results: Teenagers exposed to UNHS did not show significantly better expressive (adjusted mean difference, 0.40; 95% confidence interval [CI], −0.26 to 1.05; d = 0.32) or receptive (adjusted mean difference, 0.68; 95% CI, −0.56 to 1.93; d = 0.28) language skills than those who were not. Those who had their hearing loss confirmed by 9 months of age did not show significantly better expressive (adjusted mean difference, 0.43; 95% CI, −0.20 to 1.05; d = 0.35) or receptive (adjusted mean difference, 0.95; 95% CI, −0.22 to 2.11; d = 0.42) language skills than those who had it confirmed later. In all cases, effect sizes were of small size and in favor of those exposed to UNHS or confirmed by 9 months. Subgroup analysis indicated larger beneficial effects of early confirmation for those deaf or hard of hearing teenagers without cochlear implants (N = 48; 80% of the sample), and these benefits were significant in the case of receptive language outcomes (adjusted mean difference, 1.55; 95% CI, 0.38 to 2.71; d = 0.78). Exposure to UNHS did not account for significant unique variance in any of the three language scores at 13–19 years beyond that accounted for by existing language scores at 6–10 years. Early confirmation accounted for significant unique variance in the expressive language information score at 13–19 years after adjusting for the corresponding score at 6–10 years (R2 change = 0.08, p = 0.03). Conclusions: This study found that while adolescent language scores were higher for deaf or hard of hearing teenagers exposed to UNHS and those who had their hearing loss confirmed by 9 months, these group differences were not significant within the whole sample. There was some evidence of a beneficial effect of early confirmation of hearing loss on relative expressive language gain from childhood to adolescence. Further examination of the effect of these variables on adolescent language outcomes in other cohorts would be valuable. PMID:28399063
Forgetting common ground: six- to seven-year-olds have an overinterpretive theory of mind.

Four- to 9-year-olds and adults (N = 256) viewed a series of pictures that were covered with occluders to reveal nondescript or identifiable parts. Participants predicted how 3 characters, 1 who had previously viewed the full picture and 2 who had not, would interpret the obstructed drawings. Results showed significant development between 4 and 9 years and between 9 years and adulthood in understanding thought diversity as well as situations in which people should think alike. There was also evidence for a U-shaped developmental curve, with 6- to 7-year-olds most often overextending the rule that people will think differently, particularly on the initial testing trials. Performance on the different interpretive theory-of-mind measures was differentially related to individual differences in inhibitory control and verbal working memory.
Trends in National Emergency Medicine Conference Didactic Lectures Over a 6-Year Period.

National conference didactic lectures have traditionally featured hour-long lecture-based presentations. However, there is evidence that longer lectures can lead to both decreased attention and retention of information. The authors sought to identify trends in lecture duration, lecture types, and number of speakers at four national emergency medicine (EM) conferences over a 6-year period. The authors performed a retrospective analysis of the length, number of speakers, and format of didactic lectures at four different national EM conferences over 6 years. The authors abstracted data from the national academic assemblies for the four largest not-for-profit EM organizations in the United States: American Academy of Emergency Medicine, American College of Emergency Physicians, Council of Emergency Medicine Residency Directors, and Society for Academic Emergency Medicine. There was a significant yearly decrease in the mean lecture lengths for three of the four conferences. There was an increase in the percentage of rapid fire sessions over the preceding 2 years with a corresponding decrease in the percentage of general educational sessions. There was no significant difference in the mean number of speakers per lecture. An analysis of 4210 didactic lecture sessions from the annual meetings of four national EM organizations over a 6-year period showed significant decreases in mean lecture length. These findings can help to guide EM continuing medical education conference planning and research.

Transient calculations of the Goddard Institute for Space Studies general circulation model for the climatic signal of volcanic eruptions are analyzed. By compositing the output for two different volcanoes for scenario A and five different volcanos for scenario B, the natural variability is suppressed and the volcanic signals are extracted. Significant global means surface air temperature cooling and precipitation reduction are found for several years following the eruptions, with larger changes in the Northern Hemisphere (NH) than in the Southern Hemisphere. The global-average temperature response lasts for more than four years, but the precipitation response disappears after three years. Themore » largest cooling in the model occurs in the NH summer of the year after spring eruptions. Significant zonal-average temperature reductions begin in the tropics immediately after the eruptions and extend to 45[degrees]S-45[degrees]N in the year after the eruptions. In the second year, cooling is still seen from 30[degrees]S to 30[degrees]N. Because of the low variability in this model as compared to the real world, these signals may appear more significant here than they would be attempting to isolate them using real data. The results suggest that volcanoes can enhance the drought in the Sahel. No evidence was found that stratospheric aerosols from the low-latitude volcanic eruptions can trigger ENSO events in this model.« less

Purpose: Given the paucity of data on racial disparities in ductal carcinoma in situ (DCIS), the data from a multi-institutional cohort of DCIS patients treated with breast-conserving surgery and whole breast radiation therapy (RT) were analyzed to determine whether racial disparities or differences exist. Methods and Materials: A total of 533 white and 76 black DCIS patients from 3 university-based cancer centers were uniformly treated with breast-conserving surgery and RT. All patient data were collected and analyzed as a function of race. Results: The median follow-up was 5.2 years. No significant racial differences were seen in tumor size, age atmore » diagnosis, estrogen receptor status, necrosis, or grade (all P>.05). Of the treatment parameters, the RT dose delivered, boost, positive margin rates, frequency of hormone receptor status assessment, and receipt of hormonal therapy for the 2 cohorts did not significantly differ (all P>.05). The local relapse-free survival was similar at 5 years (96.1% and 98.1%, P=.399) and 10 years (92.8% vs 95.8%, P=.360), with no significant overall survival difference at 10 years (94.0% vs 88.9%, P=.290) between the white and black patients, respectively. On multivariate analysis, race was not an independent predictor of local relapse-free survival or overall survival when accounting for age, grade, and margin status. Conclusion: In our large cohort of DCIS patients uniformly treated at 3 institutions with breast conservation without any apparent differences in treatment delivery parameters, we demonstrated that the clinical and pathologic features and local survival outcomes did not differ as a function of race. Our results suggest that when black patients with DCIS are appropriately selected for breast conservation and receive adjuvant RT without racial disparities in the treatment parameters, differences in the outcomes as a function of race do not exist.« less
Cross-linked polyethylene does not reduce wear in total knee arthroplasty.

To compare two different types of inserts: Ultra-high molecular weight polyethylene (UHMWPE) and cross-linked polyethylene with a quantitative and qualitative study of polyethylene wear particles in synovial fluid 3 years after total knee arthroplasty. A prospective, randomized, controlled cohort study with blinded evaluation was carried out on 25 patients undergoing staged bilateral total knee replacement, 6 months apart. Knee arthrocentesis was performed on 12 patients 3 years after surgery, and the polyethylene particles were analyzed. No significant differences were found in the number of particles generated by the two different types of inserts at 3 years from total knee arthroplasty (3,000×: x¯ cross-linked=849.7; x¯ UHMWPE=796.9; P=.63; 20,000×: x¯ cross-linked=66.3; x¯ UHMWPE=73.1; P=.76). Likewise, no differences in the probability of finding elongated (χ 2 =0.19; P=.66) or rounded (χ 2 =1.44; P=.23) particles in both types of inserts were observed. However, the probability of finding fibrillar particles is 3.08 times greater in UHMWPE. Cross-linked polyethylene does not significantly reduce the generation of polyethylene particles in patients with total knee arthroplasty, 3 years after the surgical procedure.

Background We aimed to evaluate the effectiveness of a community-wide campaign (CWC) for promoting physical activity in middle-aged and elderly people. Methods A cluster randomized controlled trial (RCT) with a community as the unit of randomization was performed using a population-based random-sampled evaluation by self-administered questionnaires in the city of Unnan, Shimane Prefecture, Japan. The evaluation sample included 6000 residents aged 40 to 79 years. We randomly allocated nine communities to the intervention group and three to the control group. The intervention was a CWC from 2009 to 2010 to promote physical activity, and it comprised information, education, and support delivery. The primary outcome was a change in engaging in regular aerobic, flexibility, and/or muscle-strengthening activities evaluated at the individual level. Results In total, 4414 residents aged 40–79 years responded to a self-administered questionnaire (73.6% response rate). Awareness of the CWC was 79% in the intervention group. Awareness and knowledge were significantly different between the intervention and control groups, although there were no significant differences in belief and intention. The 1-year CWC did not significantly promote the recommended level of physical activity (adjusted odds ratio: 0.97; 95% confidence interval: 0.84–1.14). Conclusions This cluster RCT showed that the CWC did not promote physical activity in 1 year. Significant differences were observed in awareness and knowledge between intervention and control groups as short-term impacts of the campaign. Trial registration UMIN-CTR UMIN000002683 PMID:23570536

Microbial infection is one of the most significant causes of ear diseases, but microbial profiles are very diverse according to the diseases and change over time. The purpose of the study was to clarify differences and chronological changes in causative pathogens among infectious ear diseases over the last 20 years, and to identify antibiotic resistance. In total, 1191 isolates were included from patients diagnosed with chronic otitis media without cholesteatoma (COM), cholesteatomatous otitis media (Chole), middle ear effusion (MEE), including acute otitis media and otitis media with effusion, and external otitis (EO). Data were collected periodically for the years 1995, 2000, 2004, 2009, and 2013. Culture results and antibiotic resistance were assessed. The most common microorganism identified was S. aureus. The microbial profiles differed significant among the COM, Chole, and MEE groups (p < 0.001). In contrast, there was no distinct difference between COM and EO (p = 0.332). COM, Chole, and MEE also showed significant chronological changes in microbial profiles over time. The frequency of CNS increased markedly in COM and Chole (p = 0.029 and 0.028, respectively); however, S. pneumoniae infection decreased significantly in MEE (p = 0.016). Methicillin-resistant S. aureus (MRSA) demonstrated a constant trend (p = 0.564), whereas ciprofloxacin-resistant P. aeruginosa increased over time (p < 0.001). Microbial profiles have changed over a 20-year period. Increases in the frequency of coagulase-negative Staphylococcus (CNS) and bacterial resistance to ciprofloxacin, used widely in treating ear infections, are noteworthy.

We studied the behavioral and cognitive abnormalities in 45 children with obstructive sleep apnea and 30 healthy controls, aged 3 to 13 years. Psychological tests were performed in both groups at baseline and at 12 months. Preoperatively, all cognitive and behavioral disturbances were higher in the study group than in the control group: attention in 46.7% of cases in the study group versus 20% in the control group (P=.016), anxiety 60.9% versus 40.9% (not significant); memory 55.6% versus 36.7% (P=.019), spatial structuring 64.4% versus 36.7% (P=.017), hyperactivity 42.9% versus 12.5% (P=.016), and attention deficit 46.4% versus 8.3% (P=.003). After one year we observed more disturbances in all variables in the study group. However, significant differences remained only in spatial structure (31.3% versus 3.3%, P=.017), and attention deficit (40.5% versus 16.7%, P=.031). The percentages of patients that improved in one year were not significantly different between both groups. Behavioral and cognitive disturbances in children with sleep apnea were partially resolved following adenotonsillectomy. Improvements in the cognitive and behavioral variables did not differ significantly from those the normal evolution of the individual, and were independent of the resolution of respiratory disorders.

To investigate the effects of electromagnetic radiation on the physiological indices and immune function of operators. The general conditions and electromagnetic radiation awareness rate of 205 operators under electromagnetic radiation were evaluated using a self-designed questionnaire. Physical examination, electrocardiography, and routine urine test were performed in these operators. Peripheral blood was collected from the operators under electromagnetic radiation for blood cell counting and biochemical testing, and their peripheral blood lymphocytes were cultured for determination of chromosomal aberrant frequency and micronucleus frequency. The data from these operators (exposure group) were compared with those of 95 ordinary individuals (control group). The chief complaint of giddiness, tiredness, dizziness, and amnesia showed significant differences between the exposure group and control group (P < 0.01), and the difference in headache became larger with an increase in working years. The awareness rate of electromagnetic radiation damage was significantly higher in the exposure group than in the control group. The difference in bradycardia was significant between the two groups (P <0.01), and the incidence was higher with longer working years. Significant differences between the two groups were also found in the numbers of individuals with elevated alanine aminotransferase, total bilirubin, and direct bilirubin (P < 0.01), populations with increased lymphocyte ratio and decreased neutrophil ratio (P < 0.01), populations with positive occult blood, urobilinogen, and bilirubin tests, and the number of individuals with increased micronucleus frequency of cultured peripheral blood lymphocytes (P < 0.01). In addition, the exposure group had significantly increased complement C3 and C4 (P < 0.01), significantly increased IgG (P < 0.05), and significantly decreased IgM (P < 0.01), as compared with the control group. Electromagnetic radiation may lead to the changes in physiological indices, genetic effects, and immune function and affect the health and immune function in operators. The adverse effects are increased as the working years increase. So it is important to strengthen occupational protection of operators under electromagnetic radiation.

To assess the medical oncology (MO) physician workforce diversity by race, Hispanic ethnicity, and sex, with attention to trainees. Public registries were used to assess 2010 differences among MO practicing physicians, academic faculty, and fellows; internal medicine (IM) residents; and the US population, using binomial tests with P < .001 significance adjusting for multiple comparisons. Significant changes in fellow representation from 1986 to 2011 were assessed. Female representation as MO fellows (45.0%) was significantly increased compared with faculty (22.4%) and practicing physicians (27.4%); was no different than IM residents (44.7%, P = .853); and increased significantly, by 1.0% per year. Women were significantly underrepresented as practicing physicians, faculty, and fellows compared with the US population (50.8%). Traditionally underrepresented minorities in medicine (URM) were significantly underrepresented as practicing physicians (7.8%), faculty (5.7%), and fellows (10.9%), versus US population (30.0%). Hispanic MO fellows (7.5%) were increased compared with faculty (3.9%) and practicing physicians (4.1%); Black fellows (3.1%) were no different than faculty (1.8%, P = .0283) or practicing physicians (3.5%, P = .443). When comparing MO fellows versus IM residents, there were no differences for American Indians/Alaska Natives/Native Hawaiians/Pacific Islanders (0.3%, 0.6%, respectively, P = .137) and Hispanics (7.5%, 8.7%, P = .139), unlike Blacks (3.1%, 5.6%, P < .001). There has been no significant change in URM representation, with negligible changes every 5 years for American Indians/Alaska Natives/Native Hawaiians/Pacific Islanders (-0.1%), Blacks (-0.3%), and Hispanics (0.3%). Female fellow representation increased 1% per year over the quarter century indicating historical gains, whereas URM diversity remains unchanged. For Blacks alone, representation as MO fellows is decreased compared with IM residents, suggesting greater disparity in MO training. Copyright © 2014 by American Society of Clinical Oncology.

To assess changes of prostate-specific antigen (PSA) testing following recent US Preventive Services Task Force (USPSTF) prostate cancer screening recommendations using 2005 to 2013 National Health Interview Survey data. We calculated the percentage of PSA testing among men ≥40 years by age group and age-adjusted race for each survey year. Differences between years were assessed with linear contrasts after combining all years' data. The overall percentage of PSA testing was highest in 2008 and decreased significantly in 2013. Compared with 2008, each age group had significantly lower screening percentages in 2013, especially men ≥75 years old (-14.0% points; P < .001). Both men aged 50 to 74 and men aged ≥75 had significantly lower percentages in 2013 than in 2010. For white and black men, the PSA testing percentages were highest in 2008 and decreased significantly in 2013. Only white men had a significantly lower percentage in 2013 than in 2010. Significant declines in PSA testing from 2008 to 2013 in men ≥75 years old may reflect the impact of the 2008 USPSTF recommendations. While the cause of the decreases in PSA testing between 2010 and 2013 among men aged 50 to 74 years old and white men is unknown, the decreases may suggest the early effects of the 2012 recommendations. © Copyright 2015 by the American Board of Family Medicine.

To assess the catch-up growth of long-term physically neglected and emotionally abused preschool male children who have entered foster residential care and remained 1 year after initial placement. Longitudinal study over a 7-year period (1994-2001). So that a child was eligible for the study, three selection criteria were included: (1) aged between 24 and 48 months at the time of entry into residential facility, (2) having suffered both long-term (more than 6 months) physically neglected and emotionally abused, and (3) having stayed in foster care for 1 year after initial placement. Weight, height, and head circumference were established upon entry and re-assessed 1 year after initial placement, calculating the annual growth velocity. Results were compared with normal regional longitudinal standards of reference (Z score). Student's t test was used to assess statistically significant differences. During the study period, 87 children aged between 24 and 48 months (54 male/33 female) were admitted to residential facility after having suffered both long-term physical neglect and emotional abuse. Nevertheless, only 20 children (23% of the total admissions) met the third selection criteria (having remained 1 year after initial placement). Of these children, all were males and at placement they were between the ages of 30 and 42 months, with an average age of 36 months (1.9 SD). At placement, the analyzed parameters were below the normal standards, showing a statistically significant difference for height (Z score = -1.29; p = .008) and weight (Z score = -.75; p = .038). The annual growth velocity for all parameters was above the normal standards showing a statistically significant difference for height (Z score = +1.43; p = .009). One year after initial placement, the significant differences for height (Z score = -.68; p = .102) and weight (Z score = -.31; p = .435) with respect to the normal standards disappeared, though still remained below, showing a significant catch-up growth for height (improvement height Z = +.61 SD). At placement, the both long-term physically neglected and emotionally abused preschool age male children showed a mild form of chronic malnutrition with growth failure. Growth failure was reversible after the first year of stay, which demonstrates that this delay in growth was secondary to nutritional and psychosocial factors. Placement in foster residential care was beneficial for the catch-up growth of these patients. Copyright 2002 Elsevier Science Ltd.

Pulse pressure (PP) has been associated with atrial fibrillation (AF) independent of other measures of arterial pressure and other AF risk factors. However, the impact of gender, race, age, and geographic region on the association between PP and AF is unclear. A cross-sectional study of data from 25,109 participants (65 ± 9 years, 54% women, 40% black) from the Reasons for Geographic and Racial Differences in Stroke study recruited between 2003 and 2007 were analyzed. AF was defined as a self-reported history of a previous physician diagnosis or presence of AF on ECG. Multivariable logistic regression models were used to calculate the odds ratio for AF. Interactions for age (<75 years and ≥75 years), gender, race, and region were examined in the multivariable adjusted model. The prevalence of AF increased with widening PP (7.9%, 7.9%, 8.4%, and 11.6%, for PP < 45, 45-54.9, 55-64.9, and ≥65 mm Hg, respectively, [P for trend <.001]) but attenuated with adjustment. No differences by gender, race, and region were observed. However, there was evidence of significant effect modification by age (interaction P = .0002). For those <75 years, PP ≥ 65 mm Hg compared to PP < 45 mm Hg was significantly associated with higher risk of AF in both the unadjusted and multivariable adjusted models (odds ratio = 1.66 [95% CI = 1.42-1.94] and 1.32 [95% CI = 1.03-1.70], respectively). In contrast, higher PP (55-64.9 mm Hg) among those ≥75 years was significantly associated with a lower risk of AF. The relationship between PP and AF may differ for older versus younger individuals.

To investigate the epidemiological status of glucose-6-phosphate dehydrogenase (G6PD) deficiency among children from Yunnan with unique ethnic origins. DNA samples from 11759 children were tested with fluorescent spot test, G6PD/6PGD quantitative ratio assay and hemoglobin electrophoresis. The detection rate of G6PD deficiency was 2.5%, for which boys were significantly greater than girls (3.5% vs. 1.4%, P<0.05). Significant differences were also detected among children from different ethnic groups and different regions. For ethnic Han Chinese, the detection rate was 0.7%, which was lower than the majority of ethnic minorities. By regression analysis, altitude of residence and family history both have significant influence on the calculated rate. Occurrence of G6PD deficiency seems to be influenced by gender. It also varies substantially between different ethnic groups as well as regions, e.g., more common in south. It also showed a declining trend after years of diagnosis and intervention. This survey may provide a valuable basis for counseling of G6PD deficiency in Yunnan.

Climate changes are considered to significantly impact net primary productivity (NPP). However, there are few studies on how climate changes at multiple time scales impact NPP. With MODIS NPP product and station-based observations of sunshine duration, annual average temperature and annual precipitation, impacts of climate changes at different time scales on annual NPP, have been studied with EEMD (ensemble empirical mode decomposition) method in the Karst area of northwest Guangxi, China, during 2000-2013. Moreover, with partial least squares regression (PLSR) model, the relative importance of climatic variables for annual NPP has been explored. The results show that (1) only at quasi 3-year time scale do sunshine duration and temperature have significantly positive relations with NPP. (2) Annual precipitation has no significant relation to NPP by direct comparison, but significantly positive relation at 5-year time scale, which is because 5-year time scale is not the dominant scale of precipitation; (3) the changes of NPP may be dominated by inter-annual variabilities. (4) Multiple time scales analysis will greatly improve the performance of PLSR model for estimating NPP. The variable importance in projection (VIP) scores of sunshine duration and temperature at quasi 3-year time scale, and precipitation at quasi 5-year time scale are greater than 0.8, indicating important for NPP during 2000-2013. However, sunshine duration and temperature at quasi 3-year time scale are much more important. Our results underscore the importance of multiple time scales analysis for revealing the relations of NPP to changing climate.

Chemotherapy with praziquantel (PZQ) is the mainstay of schistosomiasis control. However, there are recent concerns about tolerance or resistance to PZQ, so that monitoring its efficacy in different settings is required. A longitudinal study was conducted to evaluate the impact of PZQ for the treatment of Schistosoma haematobium infection among schoolchildren at Al Salamania, Central Sudan. Parasitological examinations for S. haematobium were performed in a cohort of schoolchildren (6-15 years of age) before and 1 year after treatment with a single dose of PZQ 40 mg/kg. Out of 562 (309 boys and 253 girls) schoolchildren recruited from three elementary schools, 420 completed one longitudinal dataset that comprised of data from two time points; baseline, and follow-up 1 year after treatment with a single dose of PZQ 40 mg/kg for S. haematobium infection. A single dose of PZQ significantly reduced the prevalence of S. haematobium infection by 83.3% (from 51.4% to 8.6%) and the geometric mean intensity of infection of positive individuals by 17.0% (from 87.7 to 72.8 eggs/10 ml of urine) 1 year after treatment. While there was no significant difference in the reduction of the prevalence of S. haematobium infection between the gender or age groups, there was a significantly higher reduction of intensity of S. haematobium infection among girls in comparison with boys. There was a significant reduction of S. haematobium infection 1 year after PZQ treatment in this setting.

Vegetated buffer strips have been recognized as an important element in overall agro-ecosystem management to reduce the delivery of non-point source pollutants from agricultural land to inland water systems. A buffer strip experiment consisting of two tree species (Eucalyptus camaldulensis and Casuarina cunninghamiana) with two planting densities and a pasture treatment was conducted to determine the effectiveness of NO(3)-N removal from a cattle feedlot effluent disposal area at Tullimba near Armidale, NSW Australia. Different management methods were applied for the buffers where grass and weeds were mowed 2-3 times during the second and third years and were not managed during the rest experimental years for the tree buffer, while grass was harvested 1-3 times per year for the pasture buffer. The differences between tree species and planting density significantly affected tree growth, but the growth difference did not significantly affect their capacities to reduce NO(3)-N in soil surface runoff and groundwater. On average for all the tree and pasture treatments, the buffer strips reduced NO(3)-N concentration by 8.5%, 14.7% and 14.4% for the surface runoff, shallow and deep groundwater respectively. The tree and pasture buffer strips were not significantly different in NO(3)-N reduction for both shallow and deep groundwater while the pasture buffer strips reduced significantly more NO(3)-N concentration in surface runoff than the tree buffer strips. Both buffer strips reduced more than 50% of surface runoff volume indicating that both the tree and pasture buffer strips were efficient at removing water and nutrients, mostly through a significant reduction in soil surface runoff volume.

To assess revision rates after knee arthroplasty by comparing the cumulative results from worldwide clinical studies and arthroplasty registers. We hypothesised that the revision rate of all clinical studies of a given implant and register data would not differ significantly. A systematic review of clinical studies in indexed peer-reviewed journals was performed followed by internal and external validation. Parameters for measurement of revision were applied (Revision for any reason, Revisions per 100 observed component years). Register data served as control group. Thirty-six knee arthroplasty systems were identified to meet the inclusion criteria: 21 total knee arthroplasty (TKA) systems, 14 unicondylar knee arthroplasty (UKA) systems, one patello-femoral implant system. For 13 systems (36%), no published study was available that contained revision data. For 17 implants (47%), publications were available dealing with radiographic, surgical or technical details, but power was too weak to compare revision rates at a significant level. Six implant systems (17%) had a significant number of revisions published and were finally analysed. In general, developers report better results than independent users. Studies from developers represent an overproportional share of all observed component years. Register data report overall 10-year revision rates of TKA of 6.2% (range: 4.9-7.8%), rates for UKA are 16.5% (range: 9.7-19.6%). Revision rates of all clinical studies of a given implant do not differ significantly from register data. However, significant differences were found between the revision rates published by developers and register data. Therefore the different data need to be interpreted in the context of the source of the information. Copyright © 2012 Osteoarthritis Research Society International. Published by Elsevier Ltd.

Studies demonstrating that higher doses of citalopram (> 40 mg) and escitalopram (> 20 mg) prolong the corrected QT interval prompted regulatory agency warnings, which are controversial, given the absence of confirmatory clinical outcome studies. We compared the risk of potential arrhythmia-related deaths for high doses of these selective serotonin reuptake inhibitors (SSRIs) to that for equivalent doses of fluoxetine, paroxetine, and sertraline. The Tennessee Medicaid retrospective cohort study included 54,220 persons 30-74 years of age without cancer or other life-threatening illness who were prescribed high-dose SSRIs from 1998 through 2011. The mean age was 47 years, and 76% were female. Demographic characteristics and comorbidity for individual SSRIs were comparable. Because arrhythmia-related deaths are typically sudden and occur outside the hospital, we analyzed out-of-hospital sudden unexpected death as well as sudden cardiac deaths, a more specific indicator of proarrhythmic effects. The adjusted risk of sudden unexpected death for citalopram did not differ significantly from that for the other SSRIs. The respective hazard ratios (HRs) for citalopram versus escitalopram, fluoxetine, paroxetine, and sertraline were 0.84 (95% CI, 0.40-1.75), 1.24 (95% CI, 0.75-2.05), 0.75 (95% CI, 0.45-1.24), and 1.53 (95% CI, 0.91-2.55). There were no significant differences for sudden cardiac death or all study deaths, nor were there significant differences among high-risk patients (≥ 60 years of age, upper quartile baseline cardiovascular risk). Escitalopram users had no significantly increased risk for any study end point. We found no evidence that risk of sudden unexpected death, sudden cardiac death, or total mortality for high-dose citalopram and escitalopram differed significantly from that for comparable doses of fluoxetine, paroxetine, and sertraline. © Copyright 2016 Physicians Postgraduate Press, Inc.
