    This study aims to determine the risk factors associated with glycaemic control of ambulatory patients with type 2 diabetes mellitus (T2DM) who are managed in primary care. The data was retrieved from a primary care site within the Singapore Consortium of Cohort Studies-Diabetes Cohort (SCCS-DC). Demographic and clinical variables were described, in association with the risk of having a deteriorating glycaemic control (defined as an absolute increase of at least 1% HbA1c from one year to a subsequent year). Next, multivariate model was performed to define the independent effect of each factor. The longitudinal analysis of the HbA1c was performed using Generalised Estimating Equation (GEE). The 5 year longitudinal data of 1256 patients (54% Chinese, 25% Malays, 12% Indians, 9% others) were analysed. Their mean HbA1c decreased by <0.1% in the initial 3 years, but increased thereafter. 12% of them had absolute HbA1c increment of ≥1% in the first year, and 22% over 5 years. Based on GEE analysis, insulin, was associated with an increase of HbA1c (≥1%) from one year to another (all p<0.05). Compared with Chinese patients, Malays had higher HbA1c (+0.3%), Indians (+0.3%), and others (+0.2%), (all p<0.01). Patients with retinopathy had higher HbA1c (+0.2%) and those with cataract had lower mean HbA1c (-0.2%) (p<0.01). Most cohort patients achieved glycaemic control within the initial 3 years. Patients of Malay and Indian ethnicity and those with retinopathy were associated with subsequent risk of glycaemic control deterioration. Those with cataract were associated with trend towards improved glycaemic control. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Resolving the theoretical controversy on the labeling of an increasing number of excessive behaviors as behavioral addictions may also be facilitated by more empirical data on these behavioral problems. For instance, an essential issue to the classification of psychiatric disorders is information on their natural course. However, longitudinal research on the chronic vs. episodic nature of behavioral addictions is scarce. The aim of the present study, therefore, was to provide data on prevalence, substance use comorbidity, and five-year trajectories of six excessive behaviors-namely exercising, sexual behavior, shopping, online chatting, video gaming, and eating. Analyses were based on the data of the Quinte Longitudinal Study, where a cohort of 4,121 adults from Ontario, Canada was followed for 5 years (2006 to 2011). The response rate was 21.3%, while retention rate was 93.9%. To assess the occurrence of each problem behavior, a single self-diagnostic question asked people whether their over-involvement in the behavior had caused significant problems for them in the past 12 months. To assess the severity of each problem behavior reported, the Behavioral Addiction Measure was administered. A mixed design ANOVA was used to investigate symptom trajectories over time for each problem behavior and whether these symptom trajectories varied as a function of sex. The large majority of people reported having problematic over-involvement for just one of these behaviors and just in a single time period. A main effect of time was found for each problem behavior, indicating a moderately strong decrease in symptom severity across time. The time x sex interaction was insignificant in each model indicating that the decreasing trend is similar for males and females. The data also showed that help seeking was very low in the case of excessive sexual behavior, shopping, online chatting, and video gaming but substantially more prevalent in the case of excessive eating and

    Short night-time sleep duration is a possible factor contributing to childhood obesity. Our objective was to evaluate associations between sleep timing (including bedtime and waketime) and weight gain in 4- to 5-year-old children. We used cross-sectional and longitudinal regression analyses of a large, nationally representative sample of children from the Early Childhood Longitudinal Study-Birth Cohort. Data regarding the timing and duration of weekday sleep were assessed via parent questionnaire. Short sleep duration, late bedtime and early waketime were defined as those greater than one standard deviation from the mean for the group. Using linear regression adjusted for confounders, sleep duration at 4 and 5 years and bedtime at 5 years were linked to body mass index (BMI) z-score (P sleeping sleep duration (P sleep durations and later bedtimes were more likely to be obese and to gain weight over time. Pediatricians should encourage families to place children to bed at earlier times to promote longer sleep duration as a potential means of controlling weight gain. © 2014 The Authors.

    Epidemiological studies have reported that higher education (HE) is associated with a reduced risk of incident Alzheimer's disease (AD). However, after the clinical onset of AD, patients with HE levels show more rapid cognitive decline than patients with lower education (LE) levels. Although education level and cognition have been linked, there have been few longitudinal studies investigating the relationship between education level and cortical decline in patients with AD. The aim of this study was to compare the topography of cortical atrophy longitudinally between AD patients with HE (HE-AD) and AD patients with LE (LE-AD). We prospectively recruited 36 patients with early-stage AD and 14 normal controls. The patients were classified into two groups according to educational level, 23 HE-AD (>9 years) and 13 LE-AD (≤9 years). As AD progressed over the 5-year longitudinal follow-ups, the HE-AD showed a significant group-by-time interaction in the right dorsolateral frontal and precuneus, and the left parahippocampal regions compared to the LE-AD. Our study reveals that the preliminary longitudinal effect of HE accelerates cortical atrophy in AD patients over time, which underlines the importance of education level for predicting prognosis.

    Technological advances have made it easier for researchers to collect more frequent longitudinal data from survey respondents via personal computers, smartphones, and other mobile devices. Although technology has led to an increase in data-intensive longitudinal studies, little is known about attrition from such studies or the differences between respondents who complete frequently administered surveys in a timely manner, and respondents who do not. We examined respondent characteristics and behaviors associated with continued and on-time participation in a population-based intensive longitudinal study, using weekly web-based survey interviews over an extended period. We analyzed data from the Relationship Dynamics and Social Life study, an intensive longitudinal study that collected weekly web-based survey interviews for 2.5 years from 1003 18- and 19-year-olds to investigate factors shaping the dynamics of their sexual behavior, contraceptive use, and pregnancies. Ordinary least squares and logistic regression analyses showed background respondent characteristics measured at baseline were associated with the number of days respondents remained enrolled in the study, the number of interviews they completed, and the odds that they were late completing interviews. In addition, we found that changes in pregnancy-related behaviors reported in the weekly interviews were associated with late completion of interviews. Specifically, after controlling for sociodemographic, personality, contact information, and prior experience variables, we found that weekly reports such as starting to have sex (odds ratio [OR] 1.17, 95% CI 1.03-1.32, P=.01), getting a new partner (OR 1.76, 95% CI 1.53-2.03, Psurvey completion. However, young women who reported changes in pregnancy-related behaviors also had lower levels of study attrition, and completed more interviews overall, than did their counterparts. We found that measures of participation in a longitudinal study with weekly web

    To describe the long-term effects of infertility on life and partnership satisfaction. Longitudinal cohort study. A university outpatient andrology and gynecology infertility clinic. 275 men and 272 women treated for infertility between August 2000 and December 2001. None. The Life Satisfaction Questionnaire (FLZ), the Partnership Questionnaire (PFB), and sociodemographic items at baseline (T1) and 5 years later (T2). Compared with a representative sample, our male and female participants had higher Finance and Partnership scores and lower Health scores on the FLZ at T1. They also had markedly higher PFB scores, with the exception of Conflict Behavior. After 5 years (T2), 101 men and 113 women rated the Partnership and Sexuality FLZ subscales as well as all the PFB subscales statistically significantly lower than at baseline. Only the women rated the Self-esteem FLZ subscale lower than at baseline (T1). Participants who became parents had lower Leisure and Partnership FLZ subscale scores, and fathers had lower Finance FLZ subscale scores. Satisfaction declined over 5 years for both men and women, but only in the partnership-related domains. Women were more affected than men. The success of infertility treatment had only a minor influence on a couple's future satisfaction. Copyright © 2011. Published by Elsevier Inc.

    Research on family meals in the past decade has shown a positive association between family meal frequency and adolescent healthy dietary intake. However, less is known about factors within the home environment, such as parenting style, that may be associated with family meal patterns. The purpose of this study is to test cross-sectional and 5-year longitudinal associations between parenting styles (authoritative, authoritarian, permissive, and neglectful) and the frequency of family meals among adolescents. Data were from Project Eating Among Teens, a population-based study comprised of youth from diverse ethnic/racial and socioeconomic backgrounds. Two cohorts of adolescents (middle school and high school) completed in-class surveys in 1999 (Time 1) and mailed surveys in 2004 (Time 2). Multiple linear regression models were used to predict mean frequency of family meals at Time 1 and Time 2 from adolescent report of parenting style (both mother and father) at Time 1. Cross-sectional analyses included both adolescent cohorts (n=4,746) and longitudinal analyses included only the younger cohort (n=806) because family meal frequency was not assessed in the older cohort at Time 2. Cross-sectional results for adolescent girls indicated a positive association between maternal and paternal authoritative parenting style and frequency of family meals. For adolescent boys, maternal authoritative parenting style was associated with more frequent family meals. Longitudinal results indicated that authoritative parenting style predicted higher frequency of family meals 5 years later, but only between opposite sex parent/adolescent dyads. Future research should identify additional factors within the home environment that are associated with family meal frequency to develop effective interventions that result in increased family meals for youth. Also, future research should investigate the mealtime behaviors of authoritative parents and identify specific behaviors that dietetics

    The roots of the obesity epidemic need to be traced back as early in life as possible in order to develop effective means for preventing obesity and its health consequences in the future. The aim of this paper is to examine a broad range of factors that may simultaneously contribute to childhood overweight in a population-based cohort of children followed from birth to 4.5 years, to determine which factors exert the most influence in early life. The analyses were performed using data from the Quebec Longitudinal Study of Child Development 1998-2002 (QLSCD). The study follows a representative sample (n=2103) of children born in 1998 in the Canadian province of Quebec. Measured height and weight were available for 1550 children aged 4.5 years. At 4.5 years, BMI was analyzed using the US CDC sex- and age-specific growth charts. In order to study children at their highest weights at various ages, odds ratios were presented for high birth weight, weight-for-stature at or above the 95th percentile at 5 months, and BMI at or above the 95th percentile at 4.5 years. Monthly weight gain between birth and five months has been analyzed. Children were also evaluated by the Z-score obtained from the standardized weight divided by height. Factors potentially related to children's weight include sex, gestational age and birth rank, breastfeeding, mothers' smoking status during pregnancy, family type at child's birth, and family income before pregnancy and when the children were 5 months and 4.5 years old. Other parental factors such as height and overweight/obesity (based on BMI) and other maternal factors (age, education, immigrant status) were also part of the analysis. Being in the highest quintiles of weight gain between birth and 5 months, as well as maternal smoking during pregnancy, almost double the odds of being overweight at 4.5 years. Parental overweight or obesity also increased the odds of being overweight at this age, as well as being raised in middle-income or in

    Elevated blood pressure is a significant public health concern, particularly given its association with cardiovascular disease risk, including stroke. Caring for a loved one with Alzheimer disease has been associated with physical health morbidity, including higher blood pressure. Engagement in adaptive coping strategies may help prevent blood pressure elevation in this population. This 5-year longitudinal study examined whether greater participation in pleasant leisure activities was associated with reduced blood pressure in caregivers. Participants were 126 in-home spousal Alzheimer's caregivers (M [SD] age = 74.2 [7.9] years) that completed five yearly assessments. Linear mixed-effects models analysis was used to examine the longitudinal relationship between pleasant leisure activities and caregivers' blood pressure, after adjusting for demographic and health characteristics. Greater engagement in pleasant leisure activities was associated with reduced mean arterial blood pressure (B = -0.08, SE = 0.04, p = .040). Follow-up analyses indicated that engagement in activities was significantly associated with reduced diastolic (B = -0.07, SE = 0.03, p = .030) but not systolic blood pressure (B = -0.10, SE = 0.06, p = .114). In addition, mean arterial blood pressure was significantly reduced when caregiving duties ended because of placement of care recipients in nursing homes (B = -3.10, SE = 1.11, p = .005) or death of the care recipient (B = -2.64, SE = 1.14, p = .021). Greater engagement in pleasant leisure activities was associated with lowered caregivers' blood pressure over time. Participation in pleasant leisure activities may have cardiovascular health benefits for Alzheimer's caregivers.

  12. Surveillance of broad-spectrum antibiotic prescription in Singaporean hospitals: a 5-year longitudinal study.

    Full Text Available BACKGROUND: Inappropriate prescription of antibiotics may contribute towards higher levels antimicrobial resistance. A key intervention for improving appropriate antibiotic prescription is surveillance of prescription. This paper presents the results of a longitudinal surveillance of broad-spectrum antibiotic prescription in 5 public-sector hospitals in Singapore from 2006 to 2010. METHODOLOGY/PRINCIPAL FINDINGS: Quarterly antibiotic prescription data were obtained and converted to defined daily doses (DDDs per 1,000 inpatient-days. The presence of significant trends in antibiotic prescription over time for both individual and combined hospitals was tested by regression analysis and corrected for autocorrelation between time-points. Excluding fluoroquinolones, there was a significant increase in prescription of all monitored antibiotics from an average of 233.12 defined daily doses (DDD/1,000 inpatient-days in 2006 to 254.38 DDD/1,000 inpatient-days in 2010 (Coefficient = 1.13, 95%CI: 0.16-2.09, p = 0.025. Increasing utilization of carbapenems, piperacillin/tazobactam, and Gram-positive agents were seen in the majority of the hospitals, while cephalosporins were less prescribed over time. The combined expenditure for 5 hospitals increased from USD9.9 million in 2006 to USD16.7 million in 2010. CONCLUSIONS/SIGNIFICANCE: The rate of prescription of broad-spectrum antibiotics in Singaporean hospitals is much higher compared to those of European hospitals. This may be due to high rates of antimicrobial resistance. The increase in expenditure on monitored antibiotics over the past 5 years outstripped the actual increase in DDD/1,000 inpatient-days of antibiotics prescribed. Longitudinal surveillance of antibiotic prescription on a hospital and countrywide level is important for detecting trends for formulating interventions or policies. Further research is needed to understand the causes for the various prescription trends and to act on these where

    It is unknown whether a neurotrophic deficit or pathologic nerve morphology persists in keratoconus in the long term after corneal collagen cross-linking (CXL) treatment. Nerve pathology could impact long-term corneal status in patients with keratoconus. To determine whether CXL treatment of keratoconus results in normalization of subbasal nerve density and architecture up to 5 years after treatment. Observational study of 19 patients with early-stage keratoconus indicated for a first CXL treatment with longitudinal follow-up to 5 years postoperatively (examinations were performed from 2009 to 2015; analysis was performed from February to May 2015) and 19 age-matched healthy volunteers at a primary care center and a university hospital ophthalmology department. The patients with keratoconus underwent standard epithelial-off UV-A/riboflavin CXL treatment with 30-minute UV-A exposure at 3 mW/cm2 irradiance. Central corneal subbasal nerve density and subbasal nerve architecture by use of laser-scanning in vivo confocal microscopy; subbasal nerve analysis by 2 masked observers and by use of a fully automated method; wide-field mosaics of subbasal nerve architecture by use of an automated method; and ocular surface touch sensitivity by use of contact esthesiometry. Mean (SD) age of the 19 patients with keratoconus was 27.5 (7.1) years (range, 19-44 years), and minimal corneal thickness was 428 (36) μm (range, 372-497 μm). Compared with the mean (SD) preoperative subbasal nerve density of 21.0 (4.2) mm/mm2 in healthy corneas, the mean (SD) preoperative subbasal nerve density of 10.3 (5.6) mm/mm2 in the corneas of patients with stage 1 or 2 keratoconus was reduced 51% (mean difference, 10.7 mm/mm2 [95% CI, 6.8-14.6 mm/mm2]; P corneas at final follow-up (mean reduction, 8.5 mm/mm2 [95% CI, 4.7-12.4 mm/mm2]; P corneas of patients with keratoconus compared with healthy corneas. Postoperatively, the frequency of nerve looping increased, crossings were more frequent, and

    The contribution of sports related factors to predicting long-term physical activity (PA) are unclear. The purpose of this study is to examine tracking of PA during key transition periods in youth and to determine the longitudinal associations between sports club participation and PA. Participants (n = 873, baseline age 10 to 18 years) completed self-report surveys in 2009 and 2014 that included the PACE+ PA tool and sports club participation questions. Spearman correlations assessed PA tracking. ANCOVA analyses examined predictors (sports participation at baseline) of PA (follow-up), adjusting for (a) age and sex; and (b) age, sex, and baseline PA. Tracking of PA was weak-to-moderate (ρ = .16 to .47). Greater sports participation frequency at baseline significantly predicted PA at follow-up (P sports at an elite level had a medium-to-large effect on PA levels 5 years later [d = .75 adjusting for (a); d = .60 adjusting for (b)]. PA should be promoted in youth as tracking coefficients suggest it can, to an extent, continue into later life. The standard achieved in sport has a role in predicting later PA. PA promotion strategies should include frequent, high quality opportunities for sports participation.

    This population-based longitudinal study investigated the incidence, progression and risk factors for dental erosion among South Brazilian adolescents. Eight hundred and one schoolchildren attending 42 public and private schools were clinically examined at 12 years of age; clinical examinations were repeated after 2.5 years (SD=0.3). After tooth cleaning and drying, permanent incisors and first molars were classified using the Basic Erosive Wear Examination (BEWE) scoring criteria. Questionnaires were used to collect data on socio-demographic characteristics, dietary habits, toothbrushing frequency and general health. Poisson regression analysis was used to assess the association between dental erosion incidence and explanatory variables, with adjusted incidence risk ratios (IRR) and 95% CI estimated. Among those who did not have dental erosion at baseline, 49 of 680 schoolchildren (7.1%; 95% CI=5.2-9.1) developed erosive lesions over the follow-up period. Among schoolchildren who had dental erosion at baseline, 31 of 121 (25.4%; 95% CI=17.6-33.3) had new or more severe lesions. Boys were more likely to develop dental erosion than girls (IRR=1.88; 95% CI=1.06-3.32). A moderate incidence of dental erosion was observed among South Brazilian adolescents, with boys being at higher risk. The high progression rate of 25% observed here is very concerning, and it should be taken in consideration when designing preventive strategies for dental erosion. © 2017 John Wiley & Sons A/S.

    To determine whether quadriceps weakness is associated with elevated risk of worsening knee pain over 5 years. The Multicenter Osteoarthritis Study (MOST) is a longitudinal study of 50-79-year-old adults with knee osteoarthritis (OA) or known risk factors for knee OA. The predictor variable was baseline isokinetic quadriceps strength. Covariates included baseline body mass index (BMI), physical activity level, and history of knee surgery. The outcome was worsening pain reported on the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index pain subscale or knee replacement surgery between baseline and 5-year follow-up. Analyses were knee-based and used generalized estimating equations, stratified by sex to assess whether the lowest compared with the highest tertile of baseline quadriceps strength was associated with an increased risk of worsening knee pain at 5-year follow-up, controlling for age, BMI, history of knee surgery, and physical activity level as well as correlation between knees within participants. Analyses of worsening knee pain included 4,648 knees from 2,404 participants (61% female). Men with lower quadriceps strength did not have a higher risk of worsening knee pain (RR {95% CI} = 1.01 {0.78-1.32}, P = 0.9183). However, women in the lowest compared with the highest strength tertile had a 28% increased risk of worsening knee pain (RR {95% CI} = 1.28 {1.08-1.52}, P = 0.0052). Quadriceps weakness was associated with an increased risk of worsening of knee pain over 5 years in women, but not in men. Copyright © 2013 Osteoarthritis Research Society International.

    We present two patients with a long-term response to axitinib for cytokine-refractory metastatic renal cell carcinoma. One patient has had a continuing partial response for 58 months with cytokine-intolerant metastatic renal cell carcinoma and the other patient has had continuing stable disease accompanied by a mixed response for 57 months with cytokine-refractory and intolerant metastatic renal cell carcinoma. The condition of hypertension as an adverse event markedly depended on whether or not axitinib was administered. The patients responded to axitinib with an elevation of diastolic blood pressure to 90 mmHg or higher until 2 weeks after starting axitinib. To get a long-term response to axitinib, it may be important to control well the balance between treatment effect and adverse events while using drug withdrawal.

    Initial correction following nonoperative (NonOp) treatment for idiopathic clubfoot has been reported in 95% of feet by age 2; however, by age 4, approximately one third of feet undergo surgery due to relapse. The purpose of this study was to assess the longitudinal effect of growth and surgical (Sx) intervention on gait following NonOp and Sx treatment for clubfoot. Children with idiopathic clubfoot were seen for gait analysis at 2 and 5 years of age. Kinematic data were collected at both visits, and kinetic data were collected at age 5 years. Group comparisons were made between feet treated with the Ponseti casting technique (Ponseti) and the French physical therapy method (PT) and between feet treated nonoperatively and surgically. Comparisons were made between feet treated with a limited release or tendon transfer (fair) and those treated with a full posteromedial release (poor). The α was set to 0.05 for all statistical analyses. Gait data from 181 children with 276 idiopathic clubfeet were collected at both age 2 and 5 years. Each foot was initially treated with either the Ponseti (n=132) or PT (n=144) method but by the 5-year visit, 30 Ponseti and 61 PT feet required surgery. Gait outcomes showed limitations primarily in the Sx clubfeet. Normal ankle motion was only present in 17% of Ponseti and 21% of PT feet by age 5 following Sx management. Sx PT feet showed persistent intoeing at age 2 and 5. Within the Sx group, feet initially treated with PT had a clinically significant reduction in ankle power compared with those treated initially by the Ponseti method. Feet treated with posteromedial releases had significantly less ankle power than those treated with limited surgery or that remained NonOp at 5 years. This longitudinal study shows subtle changes between 2 and 5 years, and continues to support a NonOp approach in the treatment of clubfoot. Level II-therapeutic.

    Short children born small for gestational age (SGA) have below-average bone mineral density (BMD). Growth hormone (GH) treatment improves height and BMD in short SGA children. Longitudinal data on BMD in adults born SGA, after GH cessation (GH-stop), are lacking. To determine BMD in young adults born SGA during 5 years after GH-stop. In 173 GH-treated adults born SGA (SGA-GH), BMD of total body (BMDTB) and bone mineral apparent density of lumbar spine (BMADLS) were measured longitudinally at adult height (AH) and 6 months, 2 years, and 5 years thereafter. At 5 years after GH-stop (age 21 years), data were compared with 45 untreated short SGA adults (SGA-S), 59 SGA adults with spontaneous catch-up (SGA-CU), and 81 adults born appropriate for gestational age (AGA). At GH-stop (mean age 16.4 years), estimated mean (standard error) BMDTB standard deviation score (SDS) was -0.40 (0.1) in males and -0.51 (0.1) in females, followed by a trend toward a decrease of BMDTB in males to -0.59 (0.1) at 5 years after GH-stop (P = 0.06), whereas it remained stable in females [-0.57 (0.1); P = 0.33]. At GH-stop, BMADLS SDS was -0.01 (0.1) in males and -0.29 (0.1) in females, followed by a decrease in males and females to -0.38 and -0.55, respectively, at 5 years after GH-stop (P SGA-GH were similar compared with SGA-S, SGA-CU, and AGA. After GH-stop, there is a gradual decline of BMADLS, but at the age of 21 years, BMDTB and BMADLS are similar as in untreated short SGA adults.

    Little is known how health related quality of life (HRQOL) change in the transition from dialysis to renal transplantation (RTX). Longitudinal data addressing the patient-related outcomes are scarce, and particularly data regarding kidney-specific HRQOL are lacking. Thus, the aim of the current study was to assess HRQOL in patients followed from dialysis to RTX. Furthermore, to compare HRQOL in RTX patients and the general population. In a prospective study, HRQOL was measured in a cohort of 110 patients (median age 53.5 (IQR 39-62) years, GFR 54 (45-72) ml/min/1.73 m2) in dialysis and after RTX using the self-administered Kidney Disease and Quality of Life Short Form version 1.3 (KDQOL-SF). Generic HRQOL in the RTX patients was compared to that of the general population (n=5903) using the SF-36. Clinical important change after RTX was defined as difference in HRQOL of SD/2. Follow-up time was 55 (IQR 50-59) months, and time after RTX was 41 (34-51) months. Four of nine domains in kidney-specific HRQOL improved after RTX, i.e. burden of kidney disease, effect of kidney disease, symptoms and work status. In SF-36, general health, vitality, social function and role physical improved after RTX, but none of the domains improved sufficiently to be regarded as clinically relevant change. There were highly significant differences in HRQOL between RTX patients and the general population after adjustment for age and gender for all items of SF-36 except for bodily pain and mental health. HRQOL improved in the transition from dialysis to transplantation, but clinical relevant change was only obtained in the kidney specific domains. HRQOL was perceived considerably poorer in RTX patients than in the general population. Our observations point to the need of improving HRQOL even after RTX, and should encourage further longitudinal research and clinical attention during treatment shift.

    Obesity in childhood is related to multiple lifestyle factors. Our objective was to evaluate the relationship between consumption of 100% fruit juice and weight status over time among pre-school children. We used linear and logistic multivariable regression to evaluate body mass index (BMI) z-score and overweight/obese status as a function of 100% fruit juice intake for 8950 children examined at ages 2, 4 and 5 years as part of the Early Childhood Longitudinal Study-Birth Cohort, a representative sample of the United States. Cross-sectional analysis at ages 4 and 5 years showed no difference in the prevalence of overweight and obesity between consistent juice drinkers and inconsistent/non-drinkers. Longitudinal analysis found that children who drank 100% juice consistently at age 2 years had greater increases in BMI z-score by age 4 years than infrequent/non-drinkers (P growth parameters were not noted between ages 4 and 5 years. Drinking 100% fruit juice regularly at age 2 is associated with higher odds of becoming overweight between 2 and 4 years. Paediatricians and parents can discourage excessive fruit juice consumption as part of a larger effort to avoid unhealthy gain in BMI in young children. © 2015 World Obesity.

    Past research has shown links between both children's aggressive behaviour and a lack of prosocial behaviour to later maladaptation. Both types of behaviours have also been identified as crucial in children's social and emotional development and later (mal)adaptation. However, little is known about the way they predict each other over time. We utilised a large, ethnically diverse, longitudinal population sample of girls and boys (N = 1,334) to examine the bidirectional cross-lagged links between aggressive and prosocial domains of behaviour from age seven to eleven. Teacher, parent and child self-reports were utilised to assess aggressive behaviour and prosocial behaviour. The results revealed that aggressive behaviour measured one year predicted decreases in prosocial behaviour in the following year. Conversely, prosocial behaviour did not predict changes in aggressive behaviour in the subsequent year. Furthermore, peer difficulties were examined and found to be an important mediator of the link between aggressive and prosocial behaviour. Specifically, peer difficulties mediated the links between aggressive behaviour and prosocial behaviour one year later, particularly during the first three years of school attendance. Implications of the findings for the design of intervention strategies to reduce children's aggressive behaviour are discussed.

    The study's goal was to identify the beginning of 1st grade quantitative competencies that predict mathematics achievement start point and growth through 5th grade. Measures of number, counting, and arithmetic competencies were administered in early 1st grade and used to predict mathematics achievement through 5th (n = 177), while controlling for intelligence, working memory, and processing speed. Multilevel models revealed intelligence and processing speed, and the central executive component of working memory predicted achievement or achievement growth in mathematics and, as a contrast domain, word reading. The phonological loop was uniquely predictive of word reading and the visuospatial sketch pad of mathematics. Early fluency in processing and manipulating numerical set size and Arabic numerals, accurate use of sophisticated counting procedures for solving addition problems, and accuracy in making placements on a mathematical number line were uniquely predictive of mathematics achievement. Use of memory-based processes to solve addition problems predicted mathematics and reading achievement but in different ways. The results identify the early quantitative competencies that uniquely contribute to mathematics learning.

    To benchmark outcomes of a German breast cancer network with the Surveillance Epidemiology and End Results programme (SEER) of the USA from a longitudinal point of view. All women receiving primary breast cancer therapy of three hospitals in a rural district of Marburg-Biedenkopf (Germany) of time intervals 1996-1997 and 2003-2004 were used to define local benchmark objects. Data from SEER-programme contributed longitudinal benchmark objects from national level (1988-2004). All benchmark objects were compared with the time-fixed benchmark reference of SEER (2004). Stage distributions and 5-year relative survival ratios were combined to estimate standardized screening-, case-mix-, work-up-, treatment- and relative overall performance index. From the entry cohort of 877 German women, 97.7 % of the patients accounted for the institutional sample (N = 857) and 65.8 % accounted for the regional sample (N = 577). Stage distributions, relative survival ratios and indices of the German breast cancer network improved over time. Developed indices converged with SEER (2004). Effectiveness gap between one exemplary German breast cancer network and international benchmark defined by SEER has been closed. Reasons are manifold, and further research is recommended.

    Nearly 60% of patients who are intubated in intensive care units (ICUs) experience dysphagia after extubation, and approximately 50% of them aspirate. Little is known about dysphagia recovery time after patients are discharged from the hospital. To determine factors associated with recovery from dysphagia symptoms after hospital discharge for acute respiratory distress syndrome (ARDS) survivors who received oral intubation with mechanical ventilation. This is a prospective, 5-year longitudinal cohort study involving 13 ICUs at four teaching hospitals in Baltimore, Maryland. The Sydney Swallowing Questionnaire (SSQ), a 17-item visual analog scale (range, 0-1,700), was used to quantify patient-perceived dysphagia symptoms at hospital discharge, and at 3, 6, 12, 24, 36, 48, and 60 months after ARDS. An SSQ score greater than or equal to 200 was used to indicate clinically important dysphagia symptoms at the time of hospital discharge. Recovery was defined as an SSQ score less than 200, with a decrease from hospital discharge greater than or equal to 119, the reliable change index for SSQ score. Fine and Gray proportional subdistribution hazards regression analysis was used to evaluate patient and ICU variables associated with time to recovery accounting for the competing risk of death. Thirty-seven (32%) of 115 patients had an SSQ score greater than or equal to 200 at hospital discharge; 3 died before recovery. All 34 remaining survivors recovered from dysphagia symptoms by 5-year follow-up, 7 (23%) after 6 months. ICU length of stay was independently associated with time to recovery, with a hazard ratio (95% confidence interval) of 0.96 (0.93-1.00) per day. One-third of orally intubated ARDS survivors have dysphagia symptoms that persist beyond hospital discharge. Patients with a longer ICU length of stay have slower recovery from dysphagia symptoms and should be carefully considered for swallowing assessment to help prevent complications related to dysphagia.

    We compared the ability of laparoscopic antireflux surgery (LARS) and esomeprazole to control esophageal acid exposure, over a 5-year period, in patients with chronic gastroesophageal reflux disease (GERD). We also studied whether intraesophageal and intragastric pH parameters off and on therapy were associated with long-term outcomes. We analyzed data from a prospective, randomized, open-label trial comparing the efficacy and safety of LARS vs esomeprazole (20 or 40 mg/d) over 5 years in patients with chronic GERD. Ambulatory intraesophageal and intragastric 24-hour pH monitoring data were compared between groups before LARS or the start of esomeprazole treatment, and 6 months and 5 years afterward. A secondary aim was to evaluate the association between baseline and 6-month pH parameters and esomeprazole dose escalation, reappearance of GERD symptoms, and treatment failure over 5 years in patients receiving LARS or esomeprazole. In the LARS group (n = 116), the median 24-hour esophageal acid exposure was 8.6% at baseline and 0.7% after 6 months and 5 years (P esomeprazole group (n = 151), the median 24-hour esophageal acid exposure was 8.8% at baseline, 2.1% after 6 months, and 1.9% after 5 years (P esomeprazole). Gastric acidity was stable in both groups. Patients who required a dose increase to 40 mg/d had more severe supine reflux at baseline, and decreased esophageal acid exposure (P esomeprazole therapy. However, patients receiving LARS had significantly greater reductions in 24-hour esophageal acid exposure after 6 months and 5 years. Esophageal and gastric pH, off and on therapy, did not predict long-term outcomes of patients. Abnormal supine acid exposure predicted esomeprazole dose escalation.

    This study investigated the long-term effectiveness of a Life Skills program with regard to use and proneness to legal and illicit drug use across a 4.5-year study interval. The universal school-based Life Skills program IPSY (Information + Psychosocial Competence = Protection) against adolescent substance use was implemented over 3 years (basic program in grade 5 and booster sessions in grades 6 and 7). Over the same time period, it was evaluated based on a longitudinal quasi-experimental design with intervention and control group, including two follow-up assessments after program completion [six measurement points; N (T1) = 1657 German students; M age (T1) = 10.5 years]. Applying an HLM approach, results showed that participation in IPSY had a significant effect on the frequency of smoking, and proneness to illicit drug use, across the entire study period. In addition, shorter-term effects were found for the frequency of alcohol use in that intervention effects were evident until the end of program implementation but diminished 2 years later. Thus, IPSY can be deemed an effective intervention against tobacco use and proneness to and use of illicit drugs during adolescence; however, further booster sessions may be necessary in later adolescence to enhance youths' resistance skills when alcohol use becomes highly normative among peers.

    The purpose of this study is to explore whether, in the U.S., there are associations between state-level variations in mortality among young children and state abortion restriction policies - such as parental-consent requirements, parental-notification requirements, mandatory delay laws, and restrictions on Medicaid funding for abortion. To investigate this, we used NCHS Multiple Cause of Deaths public-use data files for the period 1983-2002, and compiled data on children ages 0-4 identified as having died as a result of assault/homicide in each state and year. Medicaid funding of abortion, mandatory delay laws, and parental involvement laws for minors seeking abortions were included as the main predictor variables of interest. Multivariate count data models using pooled state-year-age cohort data, with state and time fixed effects and other state-level controls, were estimated. Results indicated that, between 1983 and 2002, the average increase in the number of homicide deaths for children under 5 years of age was 5.70 per state among states that implemented stricter abortion policies over that time, and 2.00 per state for states that did not. In the count data models, parental-consent laws were associated with a 13 percent increase in child homicide deaths; parental-notification laws were associated with an 8 percent increase in child homicide deaths though the results were less robust to alternate model specifications; mandatory delay requirements were associated with a 13 percent increase in child homicide deaths. While these data do not allow us to discern precise pathways via which state abortion-restrictions can lead to more child homicide deaths, we speculate that state restrictions on abortion may result in a disproportionate increase in children born into relatively high-risk environments. Additional research is called for to explore the association of state abortion-restrictions with other measures of infant/child health and well-being. Copyright © 2012

    The aim of this study was to compare clinical results of immediate and early loading (EL) self-tapping implants placed in posterior mandibles. Twelve patients with bilateral edentulous posterior mandibular were randomly assigned to treatment either with immediate (test) or early loaded implants (control). Seventy-two self-tapping implants with SLA surface (Ø 4, 1/4, 8 mm; length 8 and 10 mm) were analyzed in this study. Test implants (36) were loaded on the day of surgery and control implants 6 weeks later. The measuring of implant stability quotient (ISQ) was performed on 0, 6th, 12th, and 52nd week after implant insertion. The bone resorption, modified plaque, and bleeding index were notified at 1 and 5 years later. After 5 years, survival in the both groups was 100%. The mean value of primary implant stability was 76.92 ± 0.79 ISQ. In the first 6 weeks, ISQ values significantly increased in the test group (77.92 ± 1.16 vs. 79.61 ± 0.90) as well as in the control group (7.92 ± 1.05 vs. 77.55 ± 0.99). A significant longitudinal increase in ISQ value was recorded in test and control group. The differences between immediate and early loaded implants were statistically insignificant (P > 0.05). At the 5 years, no statistically significant differences were found between immediate and early loaded implants with respect to mean crestal bone loss measurements (0.4 ± 0.24 vs. 0.8 ± 0.15 mm), mean bleeding index (0.22 ± 0.11 vs. 0.25 ± 0.11), and mean plaque index (0.17 ± 0.15 vs. 0.19 ± 0.20). Based on these results, the self-tapping implants inserted in posterior mandible can provide adequate primary stability value as the main factor for immediate and EL protocol. © 2013 John Wiley & Sons A/S.

    Individuals with schizophrenia exhibit marked and disproportional impairment in social cognition, which is associated with their level of community functioning. However, it is unclear whether social cognitive impairment is stable over time, or if impairment worsens as a function of illness chronicity. Moreover, little is known about the longitudinal associations between social cognition and community functioning. Forty-one outpatients with schizophrenia completed tests of emotion processing (Mayer-Salovey-Caruso Emotional Intelligence Test, MSCEIT) and social perception (Relationships Across Domains, RAD) at baseline and approximately five years later. Stability of performance was assessed using paired t-tests and correlations. Longitudinal associations between social cognition and community functioning (Role Functioning Scale, RFS) were assessed using cross-lagged panel correlation analysis. Performance on the two social cognition tasks were stable over follow-up. There were no significant mean differences between assessment points [p's≥0.20, Cohen'sd's≤|0.20|], and baseline performance was highly correlated with performance at follow-up [ρ's≥0.70, ICC≥0.83, p'scognition and community functioning was moderately large at follow-up [ρ=0.49, p=0.002]. However, baseline social cognition did not show a significant longitudinal influence on follow-up community functioning [z=0.31, p=0.76]. These data support trait-like stability of selected areas of social cognition in schizophrenia. Cross-lagged correlations did not reveal a significant unidirectional influence of baseline social cognition on community functioning five years later. However, consistent with the larger literature, a moderately large cross-sectional association between social cognition and community functioning was observed. Based on stability and cross-sectional associations, these results suggest that social cognition might have short-term implications for functional outcome rather than long

A population-based study on outcomes of children with hearing loss. Evaluations were conducted at five years of age. Participants were 470 children born with hearing loss between 2002 and 2007 in New South Wales, Victoria and Queensland in Australia, and who first received amplification or cochlear implantation by three years of age. The earlier hearing aids or cochlear implants were fitted, the better the speech, language and functional performance outcomes. Better speech perception was also associated with better language and higher cognitive abilities. Better psychosocial development was associated with better language and functional performance. Higher maternal education level was also associated with better outcomes. Qualitative analyses of parental perspectives revealed the multiple facets of their involvement in intervention. The LOCHI study has shown that early fitting of hearing devices is key to achieving better speech, language and functional performance outcomes for children with hearing loss. The findings are discussed in relation to changes in clinical practice and directions for future research.

    The literature presents conflicting results on the epigenetic effect of in vitro fertilization (IVF) on the short-term and mid-term growth of children. These contradictory results may be related to the use of heterogeneous methodologies and non-longitudinal data. The goal of this study was to compare the body mass index (BMI) of children conceived via IVF and spontaneous conception (SC) children, using longitudinal data from birth to 5 years. This study compared 118 singleton children born after in vitro fertilization, with or without intracytoplasmic sperm injection (ICSI), selected from a pre-existing single-center cohort to 320 SC children from the same geographic area. BMI and its evolution were analyzed using the mixed-effect model during three periods: before standing acquisition (from birth to 1 year of age), during standing acquisition, and the following period from 2 to 5 years of age. BMI means were not significantly different between groups regardless of the period, when adjusting for confounding factors related to parents, pregnancy, and children's characteristics and lifestyle. Nevertheless, during the standing acquisition period, children born after IVF-ICSI presented a less significant decrease in BMI (P<0.05). In addition, for each period we identified influencing factors (maternal BMI, level of wealth indicator) associated with BMI. In the study population, the suspected epigenetic influence of IVF reported in the literature was not observed for BMI from birth to 5 years of age. Further investigations need to be conducted to determine if the suspected influence of IVF on adiposity could be expressed through other parameters. Copyright © 2017 Elsevier Masson SAS.

    The World Trade Center (WTC) collapse generated caustic airborne particulates that caused chronic rhinosinusitis in exposed Fire Department of New York firefighters. Surgery was performed when symptoms remained uncontrolled despite medical management. To identify predictors of surgical intervention for chronic rhinosinusitis in firefighters exposed to airborne irritants at the WTC collapse site. We assessed in 8,227 firefighters with WTC exposure between September 11, 2001 (9/11), and September 25, 2001, including WTC-site arrival time, months of rescue and recovery work, and eosinophil concentration measured between 9/11 and March 10, 2003. We assessed the association of serum cytokines and immunoglobulins with eosinophil concentration and surgery for rhinosinusitis in 112 surgical cases and 376 control subjects with serum available from the first 6 months after exposure to the WTC collapse site. Between 9/11 and March 10, 2015, the surgery rate was 0.47 cases per 100 person-years. In the first 18 months post-9/11, surgical patients had higher mean blood eosinophil levels than study cohort patients (219 ± 155 vs. 191 ± 134; P < 0.0001). Increased surgery risk was associated with increasing blood eosinophil counts (hazard ratio [HR], 1.12 per 100 cells/μl; 95% confidence interval [CI], 1.07-1.17; P < 0.001); arriving at the WTC site on 9/11 or September 12, 2001 (HR, 1.43; 95% CI, 1.04-1.99; P = 0.03); and working 6 months or longer at the WTC site (HR, 1.48; 95% CI, 1.14-1.93; P < 0.01). Median blood eosinophil levels for surgical patients were above levels for the cohort in all 18-month intervals March 11, 2000, through March 10, 2015, using 51,163 measurements representing 97,733 person-years of observation. Increasing age, increasing IL-17A, and low IgA in serum from 2001 to 2002 predicted blood eosinophil concentration in surgical patients but not in control subjects (R(2) = 0.26, P < 0.0001; vs. R(2) = 0.008, P = 0

    Vitamin D is important for bone, cartilage and muscle function but there are few studies on its association with joint pain. To investigate whether serum vitamin D predicts change in knee and hip pain in older adults. Longitudinal population-based cohort study of randomly selected older adults (n=769) aged 50-80 years (mean 62 years); 50% were male. Serum 25-hydroxyvitamin D (25-OHD) was assessed at baseline by radioimmunoassay, and pain at baseline, 2.6 and/or 5 years using the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) questionnaire. We used linear regression with adjustment for age, sex, body mass index and season, then further adjusted for potential structural mechanisms (radiographic osteoarthritis, bone marrow lesions, chondral defects and muscle strength). Mean total knee WOMAC score was 3.2 (range 0-39). 4.2% of participants had moderate vitamin D deficiency at baseline (25-OHD 12.5-25 nmol/l). 25-OHD vitamin D deficiency independently predicts incident, or worsening of, knee pain over 5 years and, possibly, hip pain over 2.4 years. Therefore correcting moderate vitamin deficiency may attenuate worsening of knee or hip pain in elderly people but giving supplements to those with a higher 25-OHD level is unlikely to be effective.

    Delayed return to work is common after acute respiratory distress syndrome (ARDS), but has undergone little detailed evaluation. We examined factors associated with the timing of return to work after ARDS, along with lost earnings and shifts in healthcare coverage. Five-year, multisite prospective, longitudinal cohort study of 138 2-year ARDS survivors hospitalised between 2004 and 2007. Employment and healthcare coverage were collected via structured interview. Predictors of time to return to work were evaluated using Fine and Grey regression analysis. Lost earnings were estimated using Bureau of Labor Statistics data. Sixty-seven (49%) of the 138 2-year survivors were employed prior to ARDS. Among 64 5-year survivors, 20 (31%) never returned to work across 5-year follow-up. Predictors of delayed return to work (HR (95% CI)) included baseline Charlson Comorbidity Index (0.77 (0.59 to 0.99) per point; p=0.04), mechanical ventilation duration (0.67 (0.55 to 0.82) per day up to 5 days; plost earnings, with average (SD) losses ranging from US$38 354 (21,533) to US$43 510 (25,753) per person per year. Jobless, non-retired survivors experienced a 33% decrease in private health insurance and concomitant 37% rise in government-funded coverage. Across 5-year follow-up, nearly one-third of previously employed ARDS survivors never returned to work. Delayed return to work was associated with patient-related and intensive care unit/hospital-related factors, substantial lost earnings and a marked rise in government-funded healthcare coverage. These important consequences emphasise the need to design and evaluate vocation-based interventions to assist ARDS survivors return to work. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Prior research in the general population has found that social support can buffer the adverse effects of stressors on health. However, both stressors and social support may be qualitatively different for those living in urban poverty. We examined the effects of social support and poverty-specific stressors on self-rated health. We used data from the Welfare Client Longitudinal Survey (WCLS), a 5-year longitudinal study of 718 public aid recipients. We measured received social support and "net social support," defined as the difference between support received and that given to others. We used restricted cubic splines to model the stress-buffering effects of social support on self-rated health as a function of stressful life events and neighborhood disorder. Increased exposure to stressors was associated with poorer self-rated health. Evidence of stress buffering was confined to those with the heaviest exposure to stressors, and its effects decreased across increasing levels of social support. Analyses using net social support had generally more modest effects than those using received social support. Social support does not buffer the effects of stressors on health uniformly for individuals living in conditions of urban poverty. Researchers and policymakers should be cautious in overestimating the beneficial effects that social support may have on health for marginalized populations.

    The Hall Technique (HT) is a method for managing carious primary molars. Decay is sealed under pre-formed metal crowns without any caries removal, tooth preparation, or local anesthesia. The aim of this study was to compare HT clinical/radiographic failure rates with General Dental Practitioners' (GDPs) standard (control) restorations. We conducted a split-mouth, randomized control trial (132 children, aged 3-10 yrs, GDPs n = 17) in Scotland. There were 264 study teeth with initial lesions, 42% of which were radiographically > half-way into dentin, and 67% of which had Class II restorations. Teeth were randomized to HT (intervention) or GDPs' usual treatment (control). Annual clinical/radiographic follow-up data were recorded. Ninety-one patients (69%) had 48 months' minimum follow-up. At 60 months, 'Major' failures (irreversible pulpitis, loss of vitality, abscess, or unrestorable tooth) were recorded: HT, 3 (3%); control restorations, 15 (16.5%) (p = 0.000488; NNT 8); and 'Minor' failures (reversible pulpitis, restoration loss/wear/fracture; or secondary caries): HT, 4 (5%); control restorations, 38 (42%) (p < 0.000001; NNT 3). Overall, there were follow-up data for 130 patients (2-60 mos): 'Major' failures: HT, 3 (2%); control restorations, 22 (17%) (p = 0.000004; NNT 7); and 'Minor' failures, HT, 7 (5%); control restorations, 60 (46%) (p < 0.000001; NNT 3). Sealing in caries by the Hall Technique statistically, and clinically, significantly outperformed GDPs' standard restorations in the long term (Trial registration no. ISRCTN 47267892).

    Objective Body mass index (BMI) may cluster in space among adults and be spatially dependent. Whether and how BMI clusters evolve over time in a population is currently unknown. We aimed to determine the spatial dependence of BMI and its 5-year evolution in a Swiss general adult urban population, taking into account the neighbourhood-level and individual-level characteristics. Design Cohort study. Setting Swiss general urban population. Participants 6481 georeferenced individuals from the CoLaus cohort at baseline (age range 35–74 years, period=2003–2006) and 4460 at follow-up (period=2009–2012). Outcome measures Body weight and height were measured by trained healthcare professionals with participants standing without shoes in light indoor clothing. BMI was calculated as weight (kg) divided by height squared (m2). Participants were geocoded using their postal address (geographic coordinates of the place of residence). Getis-Ord Gi statistic was used to measure the spatial dependence of BMI values at baseline and its evolution at follow-up. Results BMI was not randomly distributed across the city. At baseline and at follow-up, significant clusters of high versus low BMIs were identified and remained stable during the two periods. These clusters were meaningfully attenuated after adjustment for neighbourhood-level income but not individual-level characteristics. Similar results were observed among participants who showed a significant weight gain. Conclusions To the best of our knowledge, this is the first study to report longitudinal changes in BMI clusters in adults from a general population. Spatial clusters of high BMI persisted over a 5-year period and were mainly influenced by neighbourhood-level income. PMID:26733572

    Full Text Available Abstract Background This study identified lifestyle patterns by examining the clustering of eating routines (e.g. eating together as a family, having the television on during meals, duration of meals and various activity-related behaviors (i.e. physical activity (PA and sedentary screen-based behavior in 5-year-old children, as well as the longitudinal association of these patterns with weight status (BMI and overweight development up to age 8. Methods Data originated from the KOALA Birth Cohort Study (N = 2074 at age 5. Principal component analysis (PCA was used to identify lifestyle patterns. Backward regression analyses were used to examine the association of lifestyle patterns with parent and child background characteristics, as well as the longitudinal associations between the patterns and weight status development. Results Four lifestyle patterns emerged from the PCA: a ‘Television–Snacking’ pattern, a ‘Sports–Computer’ pattern, a ‘Traditional Family’ pattern, and a “Fast’ Food’ pattern. Child gender and parental educational level, working hours and body mass index were significantly associated with the scores for the patterns. The Television–Snacking pattern was positively associated with BMI (standardized regression coefficient β = 0.05; p p = 0.06. In addition, the Sports–Computer pattern was significantly positively associated with an increased risk of becoming overweight at age 7 (OR = 1.28, p  Conclusions The current study showed the added value of including eating routines in cross-behavioral clustering analyses. The findings indicate that future interventions to prevent childhood overweight should address eating routines and activity/inactivity simultaneously, using the synergy between clustered behaviors (e.g. between television viewing and snacking.

    Health anxiety is an under-recognised but frequent cause of distress that is potentially treatable, but there are few studies in secondary care. To determine the clinical effectiveness and cost-effectiveness of a modified form of cognitive-behaviour therapy (CBT) for health anxiety (CBT-HA) compared with standard care in medical outpatients. Randomised controlled trial. Five general hospitals in London, Middlesex and Nottinghamshire. A total of 444 patients aged 16-75 years seen in cardiology, endocrinology, gastroenterology, neurology and respiratory medicine clinics who scored ≥ 20 points on the Health Anxiety Inventory (HAI) and satisfied diagnostic requirements for hypochondriasis. Those with current psychiatric disorders were excluded, but those with concurrent medical illnesses were not. Cognitive-behaviour therapy for health anxiety - between 4 and 10 1-hour sessions of CBT-HA from a health professional or psychologist trained in the treatment. Standard care was normal practice in primary and secondary care. Primary - researchers masked to allocation assessed patients at baseline, 3, 6, 12, 24 months and 5 years. The primary outcome was change in the HAI score between baseline and 12 months. Main secondary outcomes - costs of care in the two groups after 24 and 60 months, change in health anxiety (HAI), generalised anxiety and depression [Hospital Anxiety and Depression Scale (HADS)] scores, social functioning using the Social Functioning Questionnaire and quality of life using the EuroQol-5 Dimensions (EQ-5D), at 6, 12, 24 and 60 months, and deaths over 5 years. Of the 28,991 patients screened over 21 months, 5769 had HAI scores of ≥ 20 points. Improvement in HAI scores at 3 months was significantly greater in the CBT-HA group (mean number of sessions = 6) than in the standard care, and this was maintained over the 5-year period (overall p  < 0.0001), with no loss of efficacy between 2 and 5 years. Differences in the generalised anxiety ( p

    There are limited data on the long-term outcome of childhood insomnia. We explored the longitudinal course, predictors, and impact of childhood insomnia in a community-based cohort. 5-year prospective follow-up. Community-based. 611 children (49% boys) aged 9.0 ± 1.8 years at baseline; 13.7 ± 1.8 years at follow-up. NA. Chronic insomnia was defined as difficulty initiating sleep, difficulty maintaining sleep and/or early morning awakening ≥ 3 times/week in the past 12 months. General health, upper airway inflammatory diseases, and behavioral problems in recent one year were assessed at both time points, while mental health and lifestyle practice were assessed at follow-up study. The questionnaires at baseline and follow-up were reported by parents/caretakers and adolescents themselves, respectively. The prevalence of chronic insomnia was 4.2% and 6.6% for baseline and follow-up, respectively. The incidence and persistence rates of chronic insomnia were 6.2% and 14.9%, respectively. New incidence of insomnia was associated with lower paternal education level, baseline factors of frequent temper outbursts and daytime fatigue as well as alcohol use and poor mental health at follow-up. Baseline chronic medical disorders, frequent temper outbursts, and poor mental health at follow-up were associated with the persistence of insomnia in adolescents. Baseline insomnia was associated with frequent episodes of laryngopharyngitis and lifestyle practice (coffee and smoking) at follow-up. Chronic insomnia is a common problem with moderate persistent rate in children. The associations of adverse physical and mental health consequences with maladaptive lifestyle coping (smoking and alcohol) argue for rigorous intervention of childhood insomnia.

    To determine the independent contributions of family and neighbourhood environments to changes in youth physical activity and body mass index (BMI) z-score over 5 years. In 2001, 2004 and 2006, 301 children (10-12 years at baseline) had their height and weight measured (BMI was converted to z-scores using Centers for Disease Control and Prevention reference charts; see http://www.cdc.gov/growthcharts) and moderate-to-vigorous physical activity (MVPA) assessed using accelerometers. In 2001, parents reported on the home environment (social support, role modelling, rules and restrictions, physical environment) and perceived neighbourhood environment (local traffic, road safety, sporting venues, public transport), and Geographic Information Systems were used to map features of the neighbourhood environment (destinations, road connectivity, traffic exposure). Generalized estimating equations were used to predict average BMI z-score and MVPA over time from baseline home and perceived and objective neighbourhood environment factors. Among boys, maternal education and heavy traffic were inversely associated, and sibling physical activity, maternal role modelling of MVPA and the presence of dead-end roads were positively associated with MVPA. Having unmarried parents, maternal MVPA role modelling and number of home sedentary items were positively associated with BMI z-score among boys. Among girls, having siblings, paternal MVPA role modelling, physical activity rules and parental physical activity co-participation were positively associated with MVPA. Having unmarried parents and maternal sedentary behaviour role modelling were positively associated, and number of sedentary behaviour rules and physical activity items were inversely associated with BMI z-score among girls. The home environment seems more important than the neighbourhood environment in influencing children's physical activity and BMI z-score over 5 years.

    The purpose of the analyses was to study development, stability and changes in oral health behaviour - tooth brushing frequency, use of fluoride lozenges and fluoridated toothpaste in children from 1.5 to 5 years of age - and to study associations between oral health behaviour and family characteristics. This study was based on data from the Norwegian Mother and Child Cohort Study conducted by the Norwegian Institute of Public Health and data from the Public Dental Services. A total of 771 children were followed from 1.5 to 5 years of age. Questionnaires regarding oral health behaviour in children were completed by the parents three times during preschool age. More than half of the children (52%) had their teeth brushed twice daily at 1.5 years of age, increasing to 61% at 3 years and 76% at 5 years of age. At 1.5 years of age, 37% of the children used fluoride lozenges daily, increasing to 74% at 3 years and 75% at 5 years of age. The majority of the children who had started brushing twice daily and used fluoride lozenges daily at 1.5 years of age continued these behaviours until the age of 5 years. At 1.5 years of age, children who brushed twice daily were more likely to use fluoride lozenges daily than children who brushed less frequently (P = 0.03). Multiple logistic regression showed that the probability of a child having its teeth brushed twice daily continuously during preschool age was higher when both parents were of western origin [odds ratios (OR) 4.0, confidence intervals (CI) 1.3-11.9] than when one or both parents were of non-western origin. Children with one older sibling brushed more frequently (OR 1.4, CI 1.0-1.9) and used fluoride lozenges more often (OR 1.6, CI 1.1-2.2) during preschool age than children without older siblings. Oral health behaviour established in early life was stable during preschool age. The results indicate that tooth brushing frequency and use of fluoride lozenges were not in accordance with the present recommendations based

    This study aimed to test the hypothesis that there is no difference in the survival rates of molars treated according to the conventional restorative treatment (CRT) using amalgam, atraumatic restorative treatment (ART) using high-viscosity glass ionomer, and ultraconservative treatment (UCT) protocol after 3.5 years. Cavitated primary molars were treated according to CRT, ART, and UCT (small cavities were restored with ART and medium/large cavities were daily cleaned with toothpaste/toothbrush under supervision). Molar extractions resulting from toothache, sepsis, or pulp exposure were failures. The Kaplan-Meier method was used to estimate the survival curves. The numbers of treated teeth, among the 302 6-7-year-old children, were 341 (CRT), 244 (ART), and 281 (for UCT group: 109 small ART, 166 open cavities, and 6 combinations). Protocol groups were similar at baseline regarding gender and mean decayed missing filled tooth score, but not regarding age and type of surface. The numbers of molars extracted were 22 (CRT), 16 (ART), and 26 (UCT). Fistulae were most often recorded. After 3.5 years, the cumulative survival rate ± standard error for all molars treated was 90.9 ± 2.0 % with CRT, 90.4 ± 2.4 % with ART, and 88.6 ± 1.9 % with UCT (p = 0.13). Only a type of surface effect was observed over the 3.5-year period: survival rates for molars were higher for single- than for multiple-surface cavities. There was no difference in the cumulative survival rates of primary molars treated according to the CRT, ART, and UCT protocols over a 3.5-year period. Keeping cavities in primary molars biofilm-free might be another treatment option alongside restoring such cavities through conventional and ART protocols.

    Full Text Available Background. More than 50,000 cases of acute gastroenteritis are registered in children in Ukraine annually. Statistical data concerning rotavirus infection are not correct due to poor capacities of rotavirus laboratory diagnostics in medical units. The aim of the study was to estimate rotavirus infection burden, to analyze and describe rotavirus infection in children aged under 5 years old who were hospitalized into two infectious hospitals (Kyiv and Odessa within 2006–2015 period. Material and Methods. Investigation was carried according to a standard protocol, adopted by WHO. The disease severity was estimated by score scale for clinical manifestations of rotavirus gastroenteritis assessment of Vesikari. Results. At the period from December 2006 to December 2015 20,932 children aged under 5 years old were observed. Those children admitted to hospitals of infectious diseases in Kyiv and Odessa for acute gastroenteritis and met studies inclusive criteria. From them 18,384 (87.33 % children were investigated for rotavirus, i.e. wide majority of all children admitted to hospitals with gastroenteritis. The cause of their hospitalization was rotavirus infection in almost half of all children. It was mentioned that in some periods hospitalization rate for rotavirus as a cause of gastroenteritis was up to 70 % of all cases. In Ukraine incidence of rotavirus diarrhea in hospitalized children up to 5 years old was the highest one among 6 countries of the European region included into Global Rotavirus Surveillance Network. In Ukraine it was 41 % and the region mean value was 24 %. Within the total period of observation half of all hospitalizations caused by rotavirus occurred in children of first two years of life. All time the main viruses causing infection in both hospitals were of 4 genotypes: G1P[8], G2P[4], G3P[8], G4P[8]. Genotype G9P[8] possessed a significant position in Kyiv, but there were years, when it was not identified neither in Kyiv

    This report deals with the construction and management of the reverse osmosis (RO) water system for final rinsing of surgical instruments in the washer-disinfector. Numerous operational challenges were encountered in our RO water system and these were analyzed utilizing the Ishikawa Fishbone diagram. The aim was to find potential problems and promote preventive system management for RO water. It was found that the measures that existed were inappropriate for preventing contamination in the heat-labile RO water system. The storage tank was found to be significantly contaminated and had to be replaced with a new one equipped with a sampling port and water drainage system. Additional filters and an UV treatment lamp were installed. The whole system disinfection started 1.5 years later using a peracetic acid-based compound after confirming the material compatibility. Operator errors were found when a new water engineer took over the duty from his predecessor. It was also found that there were some deficiencies in the standard operating procedures (SOPs), and that on-the-job training was not enough. The water engineer failed to disinfect the sampling port and water drainage system. The RO membrane had been used for 4 years, even though the SOP standard specified changing it as every 3 years. Various bacteria, such as Rothia mucilaginosa, were cultured from the RO water sampled from the equipment. Because Rothia mucilaginosa is a resident in the oral cavity and upper respiratory tract, it is believed that the bacteria were introduced into the system by the maintenance personnel or working environment. Therefore, the presence of R. mucilaginosa implied the failure of sanitary maintenance procedures. This study suggests that water systems should be designed based on the plans for profound system maintenance. It also suggests that SOP and on-the job training are essential to avoid any operator errors. These results must be carefully considered when either constructing new

    To compare hip fracture incidence in post-menopausal females who were differently stratified for the fracture risk according to bone mineral density and proximal femur geometry. In a 5 year follow-up study, the hip fracture incidence in 729 post-menopausal females (45 of whom suffered from incident hip fracture) was assessed and compared. Forward logistic regression was used to select independent predictors of hip fracture risk, including age, age at menopause, height, weight, femoral neck bone mineral density (FNBMD), neck-shaft angle (NSA), hip axis length, femoral neck diameter and femoral shaft diameter as covariates. Fracture incidence was then calculated for the categories of young/old age, high/low FNBMD and wide/narrow NSA, which were obtained by dichotomising each hip fracture independent predictor at the value best separating females with and without a hip fracture. The hip fracture incidence of the whole cohort was significantly higher in females with a wide NSA (8.52%) than in those with a narrow NSA (3.51%). The combination of wide NSA and low FNBMD had the highest hip fracture incidence in the whole cohort (17.61%) and each age category. The combinations of narrow/wide NSA with low/high FNBMD, respectively, gave a significantly higher fracture incidence in older than in younger women, whereas women with a combined wide NSA and low FNBMD had no significantly different fracture incidence in young (14.60%) or old age (21.62%). Our study showed that NSA is effective at predicting the hip fracture risk and that the detection in early post-menopause of a wide NSA together with a low FNBMD should identify females at high probability of incident hip fracture.

    The WHO calls for affordable population-based prevention strategies for reducing the global burden of cardiovascular disease (CVD) on morbidity and mortality; however, effective, sustainable and accessible community-based approaches for CVD prevention in at-risk youth have yet to be identified. We examined the effects of implementing a daily park-based afterschool fitness programme on youth CVD risk profiles over 5 years and across area poverty subgroups. The study included 2264 youth (mean age 9.4 years, 54% male, 50% Hispanic, 47% non-Hispanic black, 70% high/very high area poverty) in Miami, Florida, USA. We used three-level repeated measures mixed models to determine the longitudinal effects of programme participation on modifiable CVD outcomes (2010-2016). Duration of programme participation was significantly associated with CVD risk profile improvements, including body mass index (BMI) z-score, diastolic/systolic blood pressure, skinfold thicknesses, waist-hip ratio, sit-ups, push-ups, Progressive Aerobic Cardiovascular Endurance Run (PACER) score, 400 m run time, probability of developing systolic/diastolic hypertension and overweight/obesity in high/very high poverty neighbourhoods (P<0.001). Diastolic blood pressure decreased 3.4 percentile points (95% CI -5.85 to -0.85), 8.1 percentile points (95% CI -11.98 to -4.26), 6.1 percentile points (95% CI -11.49 to -0.66), 7.6 percentile points (95% CI -15.33 to -0.15) and 11.4 percentile points (95% CI -25.32 to 2.61) for 1-5 years, respectively, in high/very high poverty areas. In contrast, significant improvements were found only for PACER score and waist-hip ratio in low/mid poverty areas. This analysis presents compelling evidence demonstrating that park-based afterschool programmes can successfully maintain or improve at-risk youth CVD profiles over multiple years. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available Abstract Background Schistosoma japonicum is a major public health concern in the Peoples' Republic of China (PRC, with over one million people infected and another 50 million living in areas at risk of infection. Based on ecological, environmental, population genetic and molecular factors, schistosomiasis transmission in PRC can be categorised into four discrete ecosystems or transmission modes. It is predicted that the Three Gorges Dam (TGD will impact upon the transmission of schistosomiasis in the PRC, with varying degree across the four transmission modes. We undertook longitudinal surveillance from 2002 to 2006 in sentinel villages both above and below the TGD across five provinces (Hunan, Jiangxi, Hubei, Anhui and Sichuan to determine whether there was any impact of the TGD on schistosomiasis transmission during its construction. Here we present the results from a schistosomiasis-endemic village located above the dam in Sichuan Province. Results Baseline results showed a human S. japonicum prevalence of 42.0% (95% CI: 36.6-47.5. At follow-up, results showed that the incidence of S. japonicum infection in the selected human cohort in Shian decreased by three quarters from 46% in 2003 to 11.3% in 2006. A significant (P S. japonicum infection in bovines declined from 11.8% in the first year to zero in the final year of follow-up. Conclusions The substantial decrease in human (75% and bovine (100% incidence observed in Shian village can probably be attributed to the annual human and bovine PZQ treatment of positives; as seen in drug (PZQ intervention studies in other parts of PRC. If an increase in schistosome transmission had occurred as a result of the TGD, it would be of negligible size compared to the treatment induced decline seen here. It appears therefore that the construction of the TGD had virtually no impact on schistosomiasis transmission in Shian village over the period of study. Furthermore, contrary to previous reports from

    A chart review covering the first 5 years of clinical experience with a combined dietary and exercise intervention program for the reduction of hypercholesterolemia at the National Aeronautics and Space Administration headquarters demonstrated the program's success in maintaining high-density lipoprotein cholesterol (HDL-C) levels while significantly lowering total serum cholesterol levels. This combined program also resulted in improved ratios of total serum cholesterol to HDL-C and lowered levels of low-density lipoprotein cholesterol, thus further reducing the risk for cardiovascular disease. The National Aeronautics and Space Administration Cardiovascular Risk Reduction Program was developed after it was determined that although dietary intervention alone improved total cholesterol levels, it often resulted in a more than proportionate decrease in HDL-C and a worsening of the ratio of cholesterol to HDL-C. An approach was needed that would positively affect all factors of the lipid profile. The findings from the program indicate that reduction of cardiovascular risk can be accomplished easily and effectively at the worksite through dietary intervention, personal monitoring, and a reasonable exercise program.

    Little is known about the neurodevelopmental outcomes of children older than 3 years of age born to HIV infected mother but who are HIV-uninfected (HEU), and who have been exposed in utero and early in life to HIV and to antiretroviral medications (ARVs). We conducted a longitudinal study of cognitive, visuomotor and adaptive function of HEU children, who were assessed at two ages, 3.5 and 5.5 years. Sixty-four children (33 female) were assessed. In comparison with population norms for their age, at 3.5 years of age they had scores significantly below age expectations on aspects of adaptive behavior, but at age 5.5 years, their scores did not significantly diverge from the population norms on any of the measures. Verbal intelligence was lower at age 5.5 than at age 3.5 years, although there were also improvements in some features of adaptive behavior. Exposure to PI-based ARVs (compared to NNRTIs) was associated with higher Performance IQ, visuomotor and communication scores at age 5.5 years. Birth, early growth, and sociodemographic variables were predictive of outcomes. This study is important in tracking the trajectory of neurocognitive development across the pre-school and early school age years. The findings suggest that the full impact of early ARV exposure may not be evident until a considerable period of development has occurred. The results raise the possibility of negative effects of early ARV exposure on neurodevelopment that emerge over time, and reiterate the importance of sociodemographic and early health variables for optimal development.

    Full Text Available We propose that voluntary work, characterized by social, physical and cognitive activity in later life is associated with fewer cognitive problems and lower dementia rates. We test these assumptions using 3-wave, self-reported, and registry data from the 2010, 2012, and 2014 Swedish National Prescribed Drug Register. We had three groups of seniors in our data: 1 no volunteering (N = 531, 2 discontinuous volunteering (N = 220, and 3 continuous volunteering (N = 250. We conducted a path analysis in Mplus to investigate the effect of voluntary work (discontinuously and continuously on self-reported cognitive complaints and the likelihood of being prescribed an anti-dementia treatment after controlling for baseline and relevant background variables. Our results indicated that seniors, who continuously volunteered, reported a decrease in their cognitive complaints over time, whereas no such associations were found for the other groups. In addition, they were 2.44 (95%CI [1.86; 3.21] and 2.46 (95%CI [1,89; 3.24] times less likely to be prescribed an anti-dementia treatment in 2012 and 2014, respectively. Our results largely support the assumptions that voluntary work in later life is associated with lower self-reported cognitive complaints and a lower risk for dementia, relative to those who do not engage, or only engage episodically in voluntary work.

    School readiness is best understood as a framework for assessing profiles of strengths and vulnerabilities of the preschool-age child. Very preterm (VPT) children are at high risk of difficulties in school, and understanding their school readiness skills has the potential to aid successful transition into school. The aim of this study was to determine the school readiness skills of a cohort of VPT children, compared with term controls. VPT children (gestational age school readiness skills were evaluated using a combination of parent questionnaires and direct assessments. The 5 domains of school readiness assessed were health and physical development, social-emotional skills, approaches to learning, communication skills, and cognitive skills. VPT children had standard scores ~½ to 1 SD below those of the term controls in all domains of school readiness, and these differences were not greatly affected by adjustment for social risk differences. Overall, 44% of the VPT group had vulnerabilities in more than 1 domain of school readiness, compared with only 16% of the term controls. VPT children are more likely than term controls to have significant vulnerabilities in multiple domains of school readiness, and these differences are mostly independent of social risk.

    To control the presence of Legionella in an old hospital water system, an integrated strategy of water disinfection-filtration was implemented in the university hospital Umberto I in Rome. Due to antiquated buildings, hospital water system design and hospital extension (38 buildings), shock hyperchlorination (sodium hypochlorite, 20-50 ppm of free chlorine at distal points for 1-2 h) followed by continuous hyperchlorination (0.5-1.0 mg/L at distal points) were adopted, and microbiological and chemical monitoring of the water supply was carried out in the university hospital (December 2006-December 2011). Overall, 1308 samples of cold 37.7%) and hot >45°C (17.8%) water were collected, determining residual free chlorine (0.43 ± 0.44 mg/L), pH (7.43 ± 0.29) and trihalomethanes (8.97 ± 18.56 μg/L). Legionella was isolated in 102 (9.8%) out of 1.041 water samples without filters (L. pneumophila sg 1 17.6%, L. pneumophila sg 2-14 28.4%, L. non pneumophila 53.9%), and in none of the 267 samples with filters. Legionella was recovered in 23 buildings out of 38 and 29 samples (28.4%) exceeded 103 cfu/L. When considering the disinfection treatment Legionella was isolated: before shock hyperchlorination (21.1%), 15 days after shock hyperchlorination (7.8%), 30 days after shock hyperchlorination (3.5%), during continuous hyperchlorination (5.5%) and without continuous hyperchlorination (27.3%). Continuous hyperchlorination following the shock treatment achieved >70% reduction of positive samples, whereas no continuous hyperchlorination after shock treatment was more frequently associated to Legionella isolation (OR 6.41; 95% CI 3.10-13.26; p chlorine 37 - 123.2; p chlorine levels (>0.5 < 1.0 mg/L) deteriorated water quality (organoleptic and chemical). However, shock and continuous hyperchlorination remains a valid-term option in old buildings with no water system rational design, managing problems due to hospital extension and absence of a proper hot water recirculation

    To compare clinical and radiographic outcomes of implants with a Laser-Lok®-microtextured collar to implants with a resorbable blast textured (RBT) collar after a 5-year follow-up period. Thirty-four implants with a Laser-Lok®-microtextured collar (test group [TG]) and 31 implants with an RBT collar (control group [CG]) were placed in 45 non-smoking, periodontally healthy patients. The full-mouth plaque score, full-mouth bleeding score, number of sites with plaque, and the number of sites with bleeding on probing (BOP) were recorded at baseline, and at 1-, 2-, 3-, 4-, and 5-year follow-up. Probing depth (PD) and mucosal recession were assessed at baseline and after the 5-year follow-up period. The radiographic marginal bone loss (MBL) was calculated by subtracting the bone level at the time of crown insertion from the bone level at the 5-year follow-up. An implant survival rate of 94% and of 90% was reported for the TG and the CG, respectively. No statistical differences were found between the study groups for presence of plaque (10.1% vs. 25%) or for number of sites with BOP (10.3% vs. 23%). The differences between both study groups were statistically significant for mean MBL (0.81 ± 0.24 vs. 2.02 ± 0.32 mm), mean PD (2.32 ± 0.44 vs. 4.25 ± 0.87 mm), and mean mucosal recession (0.16 ± 0.3 vs. 0.22 ± 0.3 mm). Within the limitations of this study, results suggest that the laser-microtextured implant collar surface may provide more favorable conditions for the attachment of hard and soft tissues, and reduce the level of MBL. © 2014 John Wiley & Sons A/S.

    This prospective followup study investigated subclinical atherosclerosis in relation to traditional cardiovascular disease (CVD) risk factors and inflammation in patients with rheumatoid arthritis (RA) recruited at diagnosis compared with controls. Patients diagnosed with early RA were consecutively recruited into a prospective study. From these, a subgroup aged ≤ 60 years (n = 71) was consecutively included for ultrasound measurement of intima-media thickness (IMT) and flow-mediated dilation (FMD) at inclusion (T0) and after 5 years (T5). Age- and sex-matched controls (n = 40) were also included. In the Wilcoxon signed-rank test, both IMT and FMD were significantly aggravated at T5 compared to baseline in patients with RA, whereas only IMT was significantly increased in controls. In univariate linear regression analyses among patients with RA, the IMT at T5 was significantly associated with age, systolic blood pressure (BP), cholesterol, triglycerides, Systematic Coronary Risk Evaluation (SCORE), and Reynolds Risk Score at baseline (p subclinical atherosclerosis in patients with RA. In the patients with RA, several traditional CVD risk factors at baseline significantly predicted the extent of subclinical atherosclerosis 5 years later. The inflammatory load over time augmented this prediction.

    Full Text Available Context: Type 2 diabetes mellitus doubles the odds of suffering from depressive illness. Co-morbid depression is associated with poorer outcomes in diabetes mellitus in terms of glycemic control, medication adherence, quality of life, physical activity, and blood pressure control. Aim: The present study aims to estimate the prevalence of depression among a consecutive group of patients with type 2 diabetes and assess its impact on glycemic and blood pressure control. Setting: Outpatient department of the endocrinology department of a university affiliated teaching hospital in north India. Subjects: Consecutive adult patients (18-65 years with type 2 diabetes mellitus of over 5-year duration with no prior history of psychiatric illnesses or intake of anti-depressants. Materials and Methods: A semi-structured questionnaire was used for demographic data, HbA1c was obtained to assess glycemic control, and blood pressure was recorded twice during patient interview to assess blood pressure control. Depression was assessed with the Major Depression Inventory and scores obtained were classified as consistent with mild, moderate and severe depression. Data was analyzed with SPSS v16, and multiple logistical regression test was done to compare the effect of depression on glycemic control after adjusting for age and sex. Results: Of the 80 patients interviewed, 31 (38.8% had depressive symptoms. Among them 20 (25% had mild depression, 10 (12.5% had moderate depression, and 1 (1.3% had severe depression. Conclusions: Over one third of patients with type 2 diabetes mellitus of over 5-year duration had depressive symptoms. The presence of depressive symptoms was associated with a significant worsening of glycemic control.

    The dual acid-etched (DAE) implant was commercially introduced in 1996 with a hybrid design incorporating a machined surface in the coronal region from approximately the third thread to the seating surface. This design was intended to reduce the risks of peri-implantitis and other related soft tissue complications that were reported for implants with surface roughness in the coronal region. The objective of this prospective, randomized-controlled clinical trial was to determine the incidence of peri-implantitis for a fully etched implant with the DAE surface extending to the implant platform. Patients had implant sites randomly assigned to receive one hybrid control implant and at least one fully etched test implant in support of a short-span fixed restoration to ensure that variables (e.g., demographics, jaw locations, and bone density) were consistent between groups. Prostheses were inserted 2 months after implant placement with follow-up evaluations scheduled annually for 5 years to assess mucosal health based on bleeding on probing, suppuration, and probing depths. Evaluations also included radiographic and mobility assessments. One hundred twelve patients who were enrolled at seven centers received 139 control and 165 test implants (total: 304 implants). With >5 years of postloading evaluations, there was one declaration of peri-implantitis associated with a control implant that was successfully treated later. Clinical probing and radiographic assessments did not reveal differences between groups in mucosal health outcomes or other signs of peri-implantitis. Five-year results of this randomized-controlled study showed no increased risk of peri-implantitis for fully etched implants compared to hybrid-designed implants.

    To evaluate the role of oral ondansetron in facilitating successful rehydration of under-5-year-old children suffering from acute diarrhea with vomiting and some dehydration. Children (n = 170) aged 3 months to 5 years with acute diarrhea with vomiting and some dehydration were enrolled in this double blind, randomized, placebo-controlled trial. The participants were randomized to receive either single dose of oral ondansetron (n = 85) or placebo (n = 85) in addition to standard management of dehydration according to World Health Organization guidelines. Failure of oral rehydration therapy (ORT), administration of unscheduled intravenous fluids, and amount of oral rehydration solution intake in 4 hours were the primary outcomes. Secondary outcome measures included duration of dehydration correction, number of vomiting episodes, adverse effects, and caregiver satisfaction. Failure of ORT was significantly less in children receiving ondansetron compared with those receiving placebo (31% vs 62%; P oral rehydration solution consumption was significantly more in the ondansetron group (645 mL vs 554 mL; mean difference 91 mL; 95% CI: 35-148 mL). Patients in the ondansetron group also showed faster rehydration, lesser number of vomiting episodes, and better caregiver satisfaction.

    The prevalence of overweight and obesity in children has at least doubled in the past 25 years with a major impact on health. In 2005 a prevention protocol was developed applicable within Youth Health Care. This study aims to assess the effects of this protocol on prevalence of overweight and health behaviour among children. A cluster randomised controlled trial is conducted among 5-year-old children included by 44 Youth Health Care teams randomised within 9 Municipal Health Services. The teams are randomly allocated to the intervention or control group. The teams measure the weight and height of all children. When a child in the intervention group is detected with overweight according to the international age and gender specific cut-off points of BMI, the prevention protocol is applied. According to this protocol parents of overweight children are invited for up to three counselling sessions during which they receive personal advice about a healthy lifestyle, and are motivated for and assisted in behavioural change.The primary outcome measures are Body Mass Index and waist circumference of the children. Parents will complete questionnaires to assess secondary outcome measures: levels of overweight inducing/reducing behaviours (i.e. being physically active, having breakfast, drinking sweet beverages and watching television/playing computer games), parenting styles, parenting practices, and attitudes of parents regarding these behaviours, health-related quality of life of the children, and possible negative side effects of the prevention protocol. Data will be collected at baseline (when the children are aged 5 years), and after 12 and 24 months of follow-up. Additionally, a process and a cost-effectiveness evaluation will be conducted. In this study called 'Be active, eat right' we evaluate an overweight prevention protocol for use in the setting of Youth Health Care. It is hypothesized that the use of this protocol will result in a healthier lifestyle of the

    Previous studies have demonstrated that high-intensity interval training (HIT) is superior to moderate-continuous exercise in general and in cardiovascular diseases. Recently, we also found HIT safe and efficient after heart transplantation (HTx). This study reports the 5-year long-term effects. Forty-one HTx patients who had completed the previous 12-month randomized controlled trial, comparing HIT intervention with usual care, were eligible. In particular, we measured VO2peak , muscular capacity, intravascular ultrasound, and questionnaires measuring physical and mental health. The baseline mean±SD values were as follows: age; 49.1±16.5 years, men; 68%, time since HTx: 4.1±2.2 years. Within the HIT group, initial VO2peak increased significantly from 27.7±5.7 to 31.2±5.3 mL/kg/min. However, during the next 4 years, VO2peak decreased to 26.0±6.2 mL/kg/min. The control group showed slightly decreasing VO2peak values during the entire 5-year period. The HIT group reported significantly less anxiety symptoms, but there were no long-term differences in VO2peak , muscular capacity, or cardiac allograft vasculopathy between the groups. The similar VO2peak values correspond to our findings of similar everyday activity. Our findings suggest that intermittent periods of HIT may be necessary to maintain the initial benefits gained from the intervention. However, HIT probably reduces the burden of anxiety, which is a frequent health issue following HTx. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Aim To investigate risk factors for first long-bone fractures in children up to 5 years old in order to provide evidence about which families could benefit from injury prevention interventions. Methods Population-based matched nested case–control study using The Health Improvement Network, a UK primary care research database, 1988–2004. Maternal, household and child risk factors for injury were assessed among 2456 children with long-bone fractures (cases). 23 661controls were matched to cases on general practice. Adjusted ORs and 95% CIs were estimated using conditional logistic regression. Results Fractures of long-bones were independently associated with younger maternal age and higher birth order, with children who were the fourth-born in the family, or later, having a threefold greater odds of fracture compared to first-born children (adjusted OR 3.12, 95% CI 2.08 to 4.68). Children over the age of 1 year had a fourfold (13–24 months, adjusted OR 4.09 95% CI 3.51 to 4.76) to fivefold (37+ months, adjusted OR 4.88 95% CI 4.21 to 5.66) increase in the odds of a long-bone fracture compared to children aged 0–12 months. Children in families with a history of maternal alcohol misuse had a raised odds of long-bone fracture (adjusted OR 2.33, 95% CI 1.13 to 4.82) compared to those with no documented history. Conclusions Risk factors for long-bone fractures in children less than 5 years old included age above 1 year, increasing birth order, younger maternal age and maternal alcohol misuse. These risk factors should be used to prioritise families and communities for injury prevention interventions. PMID:25398446

    Full Text Available BACKGROUND: The beneficial effect of antenatal multiple micronutrients supplementation on infant birth outcomes has been proposed by previous meta-analyses. However, their benefits on postnatal health of children have not been summarized. A meta-analysis of randomized controlled trials was conducted to evaluate the effect of maternal multimicronutrient supplementation on postnatal growth of children under 5 years of age. METHODS: We searched both published and ongoing trials through the PubMed, EMBASE, CENTRAL (OVID platform, Web of Science, BIOSIS Previews, Chinese Science Citation Database, Scopus, ProQuest, ClinicalTrials.gov, Chinese Biomedical Database, and WANFANG database for randomized controlled trials. Reference lists of included studies and relevant reviews were also reviewed for eligible studies. Standard mean difference (SMD was employed as the index for continuous variables by using fixed effects models. Trend analysis by visual inspection was applied to evaluate the change of mean difference of weight and height between the groups over time. RESULTS: Nine trials (12 titles from nine different countries were retrieved for analysis. Pooled results showed that antenatal multimicronutrient supplementation increased child head circumference (SMD = 0.08, 95% CI: 0.00-0.15 compared with supplementation with two micronutrient or less. No evidence was found for the benefits of antenatal multimicronutrient supplementation on weight (P = 0.11, height (P = 0.66, weight-for-age z scores (WAZ (P = 0.34, height-for-age z scores (HAZ (P = 0.81 and weight-for-height z scores (WHZ (P = 0.22. A positive effect was found on chest circumference based on two included studies. CONCLUSIONS: Antenatal multimicronutrient supplementation has a significant positive effect on head circumference of children under 5 years. No impact of the supplementation was found on weight, height, WAZ, HAZ and WHZ.

    Pediatric human immunodeficiency virus (HIV) infection and malnutrition are still 2 major health issues in sub-Saharan Africa including Burkina Faso where few studies have been conducted on child malnutrition and HIV infection. This study assessed the effects of antiretroviral therapy (ART) in HIV infection and also compared the prevalence of malnutrition in terms of an inadequate diet, underweight, stunting, and wasting among HIV-infected and uninfected children less than 5 years in Bobo-Dioulasso city, Burkina Faso.This was a case-control study matching for age and sex in 164 HIV-infected and 164 HIV-uninfected children. The sociodemographic characteristics of mothers and children, household food security, drinking water source, child feeding and care practices, and child anthropometric data such as body weight, height, and mid-upper arm circumference were collected.The prevalence of food insecurity and inadequate diet was 58% and 92% of children less than 5 years of age, respectively. The prevalence of underweight, stunting, and wasting was 77% versus 35%, 65% versus 61%, and 63% versus 26% in HIV-infected and uninfected children less than 5 years of age, respectively. Out of 164 HIV-infected children, 59% were on ART initiation during data collection and the median of CD4 cell counts was 1078 cells/μL. HIV-infected children on ART had greater CD4 cell counts (P = .04) and higher weight-for-age Z (P = .01) and weight-for-height Z scores (P = .03) than those without ART. HIV infection was a risk factor for those who had inadequate dietary intake [adjusted odds ratio (AOR) = 2.17, 95% confidence interval (CI) 1.17-3.62, P = .04]. In addition, HIV-infected children were more likely of being underweight (AOR = 10.24, 95% CI 4.34-24.17, P prevalence of malnutrition was observed in HIV-infected children compared with HIV-uninfected children. Except for ART, nutritional assessment and support should be included in pediatric HIV management.

    Prospective studies that investigated the influence of glycemic control in the progression of periodontitis and tooth loss during periodontal maintenance therapy (PMT) programs have not previously been reported. The aim of the present study is to evaluate associations between glycemic control status and progression of periodontitis and tooth loss among individuals during PMT. A total of 92 individuals, all recruited from a prospective cohort with 238 participants undergoing PMT, participated in this study. Diabetes control was assessed according to percentage of glycated hemoglobin (HbA1c). Individuals were matched for sex and smoking and were divided into three groups: 23 individuals with diabetes and poor glycemic control (PGC), 23 individuals with diabetes and good glycemic control (GGC), and 46 controls with no diabetes (NDC). Full-mouth periodontal examination, including bleeding on probing (BOP), probing depth (PD), and clinical attachment level, was performed at all PMT visits during a 5-year interval. Progression of periodontitis and tooth loss were significantly higher among PGC compared to GGC and NDC. The final logistic model in the final examination included: 1) for the progression of periodontitis, HbA1c ≥6.5% (odds ratio [OR] = 2.9), smoking (OR = 3.7), and BOP in >30% of sites (OR = 4.1); and 2) for tooth loss, HbA1c ≥6.5% (OR = 3.1), smoking (OR = 4.1), and PD 4 to 6 mm in ≤10% of sites (OR = 3.3). PGC individuals, especially smokers, presented with a higher progression of periodontitis and tooth loss compared to NDC and GGC individuals. This result highlights the influence of glycemic control in maintaining a good periodontal status.

    Type 2 diabetes mellitus (DM) is known to be closely associated with lifestyle and obesity and has a prevalence that increases with age. This study aimed to assess the short-term composite effect of diet, physical activity, psychosocial health, and waist circumference (WC) on the incidence of DM in the elderly and to provide a lifestyle-based predictive index.We used baseline measurements (2009-2013) of 5349 community-dwelling participants (aged 55 years and older, 52% female) of the Healthy Aging Longitudinal Study in Taiwan (HALST) for fasting plasma glucose, HbA1C, serum cholesterol, triglycerides, blood pressures, WC, and outcomes of home-visit questionnaire. Principal component analysis (PCA) was used to identify participants with a healthy lifestyle (HLF: higher diet, physical activity, and psychosocial scores) and a lower WC, with cutoffs determined by the receiver-operating characteristics. A Cox regression model was applied to 3424 participants without DM at baseline by linking to their National Health Insurance records (median follow-up of 3.1 years).In total, 247 new DM cases (7.2%) were identified. The HLF and lower WC group had a relative risk (RR) of DM of 0.54 (95% CI 0.35-0.82) compared to the non-HLF and higher WC group. When stratified by the presence of impaired glucose tolerance (IGT) or metabolic syndrome (MS), only participants with IGT/MS showed significant risks (RR 0.55; 95% CI 0.33-0.92). However, except for WC, the individual lifestyle factors were nonsignificant in the overall model without PCA.A composite protective effect of HLF and normal WC on DM within 5 years was observed, especially in those with IGT or MS. Psychosocial health constituted an important lifestyle factor in the elderly. The cutoffs identified could be used as a lifestyle-based risk index for DM. Maintaining an HLF to prevent DM is especially important for the elderly.

    Full Text Available Abstract Background Our group recently completed a randomized controlled trial, evaluating the efficacy of providing 5 weeks of free nicotine replacement therapy (NRT; in the form of the nicotine patch by expedited postal mail without behavioral assistance to regular adult smokers interested in receiving it. The findings revealed that mailed provision of nicotine patches resulted in more than a doubling of quit rates at a six-month follow-up compared to a no intervention control group. While this trial provided evidence for the effectiveness of mailed nicotine patches in promoting cessation, the findings speak only to the short term effectiveness of this approach. As relapse to smoking is known to occur beyond the 6 month period, it is important to evaluate whether the net benefit of NRT in naturalistic settings can be maintained long-term. The present study aims to perform a 5-year follow-up survey of participants in the original trial to evaluate the long-term effectiveness of mailed NRT. Methods/Design Trained interviewers will contact participants in the randomized controlled trial 5 years post-enrollment. A total of 924 participants will be eligible to be contacted. Interviewers will first assess participants’ smoking status and their level of nicotine dependence. Participants reporting not currently smoking will be asked whether they have smoked tobacco, even a puff, in the last 30 days (primary outcome measure: 30-day point prevalence abstinence, past 6 months (secondary outcome measure: prolonged 6-month abstinence, and since the 8-week follow-up survey (secondary outcome measure: > 4 year continuous abstinence. Interviewers will be blind to experimental condition at the time the primary outcome measure will be assessed. It is hypothesized that participants who received nicotine patches at baseline will display significantly higher quit rates at the 5-year follow-up as compared to participants who did not receive nicotine patches

    Full Text Available Abstract Background The prevalence of overweight and obesity in children has at least doubled in the past 25 years with a major impact on health. In 2005 a prevention protocol was developed applicable within Youth Health Care. This study aims to assess the effects of this protocol on prevalence of overweight and health behaviour among children. Methods and design A cluster randomised controlled trial is conducted among 5-year-old children included by 44 Youth Health Care teams randomised within 9 Municipal Health Services.

    To compare healthcare costs and utilization among participants in a study of two active lifestyle interventions implemented in the workplace and designed to foster awareness of and attention to health with a propensity score matched control group. We retrospectively compared changes in healthcare (HC) utilization among participants in the mindfulness intervention (n=84) and the diet/exercise intervention (n=86) to a retrospectively matched control group (n=258) drawn for this study. The control group was matched from the non-participant population on age, gender, relative risk score, and HC expenditures in the 9 month preceding the study. Measures included number of primary care visits, number and cost of pharmacy prescriptions, number of hospital admissions, and overall healthcare costs tracked for 5 years after the intervention. Significantly fewer primary care visits (pgroups as compared to controls, with a non-significant trend towards lower overall HC utilization (4,300.00 actual dollar differences) and hospital admissions for the intervention groups after five years. Pharmacy costs and number of prescriptions were significantly higher for the two intervention groups compared to controls over the five years (p<0.05), yet still resulted in less HC utilization costs, potentially indicating greater self-management of care. This study provides valuable information as to the cost savings and value of providing workplace lifestyle interventions that focus on awareness of one's body and health. Health economic studies validate the scale of personal and organization health cost savings that such programs can generate. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Dynamic robustness and stability control is a requirement for self-driving of autonomous vehicle. Longitudinal control technique of autonomous vehicle is basic theory and one key complex technique which must have the reliability and precision of vehicle controller. The longitudinal control technique is one of the foundations of the safety and stability of autonomous vehicle control. In our paper, we present a longitudinal control algorithm based on cloud model for Mengshi autonomous vehicle to ensure the dynamic stability and tracking performance of Mengshi autonomous vehicle. The longitudinal control algorithm mainly uses cloud model generator to control the acceleration of the autonomous vehicle to achieve the goal that controls the speed of Mengshi autonomous vehicle. The proposed longitudinal control algorithm based on cloud model is verified by real experiments on Highway driving scene. The experiments results of the acceleration and speed show that the algorithm is validity and stability.

    Although cardiovascular risk factors (CVRF) are well known, their degree of control is not optimal. The aim of this study is to assess the evolution and control of CVRFs after 5 years of monitoring a population-based cohort and their association with the incidence of peripheral arterial disease (PAD). Prospective cohort study recruited between 2006-2008. Second phase between 2011-2012. An ankle brachial index was determined for all participants in both phases. Demographic variables, CVRF and previous cardiovascular events, blood pressure, total cholesterol and its fractions (HDL, LDL), triglycerides, glucose and glycosylated hemoglobin levels in diabetic patients and the cardiovascular risk score according to the REGICOR table were recorded. A total of 2,125 individuals were analyzed. We observed an increase in the prevalence of hypertension (HT) (15.4%), diabetes (DM) (8.2%) and hypercholesterolemia (20.4%), with no changes in obesity and smoking. The cardiovascular risk determined on the basis of the REGICOR table remained at around 5.5%. We observed an increased control of CVRF throughout the follow-up period, except in the case of DM and obesity. In the multivariate analysis, uncontrolled HT 2-folded the risk of onset of PAD (odds ratio [OR] 2.3; 95% confidence interval [95% CI] 1.3-4.1), whereas smoking 5-folded this risk (OR 5.0; 95% CI 2.5-10.2). Smoking and uncontrolled HT increase the risk of onset of PAD in this population. Despite the increase in drug treatments, the control of CVRFs continues to be suboptimal.

    We previously reported modest clinical 3-year benefit for topical imiquimod compared with surgery for superficial or nodular basal cell carcinoma at low-risk sites in our noninferiority randomized controlled SINS trial. Here we report 5-year data. Participants were randomized to imiquimod 5% cream once daily (superficial basal cell carcinoma, 6 weeks; nodular basal cell carcinoma, 12 weeks) or excisional surgery (4-mm margin). The primary outcome was clinical absence of initial failure or signs of recurrence at the 3-year dermatology review. Five-year success was defined as 3-year success plus absence of recurrences identified through hospital, histopathology, and general practitioner records. Of 501 participants randomized, 401 contributed to the modified intention-to-treat analyses at year 3 (primary outcome), 383 (96%) of whom had data at year 5. Five-year success rates for imiquimod were 82.5% (170/206) compared with 97.7% (173/177) for surgery (relative risk of imiquimod success = 0.84, 95% confidence interval = 0.77-0.91, P < 0.001). These were comparable to year 3 success rates of 83.6% (178/213) and 98.4% (185/188) for imiquimod and surgery, respectively. Most imiquimod treatment failures occurred in year 1. Although surgery is clearly superior to imiquimod, this study shows sustained benefit for lesions that respond early to topical imiquimod. Copyright © 2016 The Authors. Published by Elsevier Inc.

    Gap balancing (GB) has been noted to sacrifice joint-line maintenance to improve gap symmetry. This study aims to determine whether this change affects function or quality of life in the midterm. A prospective blinded randomized controlled trial was completed with 103 patients randomized to measured resection (n = 52) or GB (n = 51). Primary outcome measured was femoral component rotation. Secondary outcomes measured were joint-line change, gap symmetry, and function and quality-of-life outcomes. At 5 years, 83 of 103 patients (85%) were assessed. There was no significant difference between groups in terms of functional or quality of life outcomes. A subgroup analysis revealed that there was no significant association between those with asymmetrical flexion and/or extension or medial and/or lateral gaps during knee replacement and subsequent functional outcomes. No significant difference was detected with those with an elevated joint line and postoperative function. In the midterm, the resultant change in joint-line and maintained gap symmetry noted with GB does not result in significant change to function or quality of life. Copyright © 2017 Elsevier Inc.

    Full Text Available There are very limited data on children with pneumonia in Mali. The objective was to assess the etiology and factors associated with community-acquired pneumonia in hospitalized children <5 years of age in Mali.A prospective hospital-based case-control study was implemented in the Pediatric department of Gabriel Touré University Hospital at Bamako, Mali, between July 2011-December 2012. Cases were children with radiologically-confirmed pneumonia; Controls were hospitalized children without respiratory features, matched for age and period. Respiratory specimens, were collected to identify 19 viruses and 5 bacteria. Whole blood was collected from cases only. Factors associated with pneumonia were assessed by multivariate logistic regression.Overall, 118 cases and 98 controls were analyzed; 44.1% were female, median age was 11 months. Among pneumonia cases, 30.5% were hypoxemic at admission, mortality was 4.2%. Pneumonia cases differed from the controls regarding clinical signs and symptoms but not in terms of past medical history. Multivariate analysis of nasal swab findings disclosed that S. pneumoniae (adjusted odds ratio [aOR] = 3.4, 95% confidence interval [95% CI]: 1.6-7.0, human metapneumovirus (aOR = 17.2, 95% CI: 2.0-151.4, respiratory syncytial virus [RSV] (aOR = 7.4, 95% CI: 2.3-23.3, and influenza A virus (aOR = 10.7, 95% CI: 1.0-112.2 were associated with pneumonia, independently of patient age, gender, period, and other pathogens. Distribution of S. pneumoniae and RSV differed by season with higher rates of S. pneumoniae in January-June and of RSV in July-September. Pneumococcal serotypes 1 and 5 were more frequent in pneumonia cases than in the controls (P = 0.009, and P = 0.04, respectively.In this non-PCV population from Mali, pneumonia in children was mainly attributed to S. pneumoniae, RSV, human metapneumovirus, and influenza A virus. Increased pneumococcal conjugate vaccine coverage in children could significantly reduce the

    Full Text Available To explore the longitudinal effect of chronic comorbid diseases on glycemic control (HbA1C and systolic blood pressure (SBP in type 2 diabetes patients.In a representative primary care cohort of patients with newly diagnosed type 2 diabetes in The Netherlands (n = 610, we tested differences in the five year trend of HbA1C and SBP according to comorbidity profiles. In a mixed model analysis technique we corrected for relevant covariates. Influence of comorbidity (a chronic disease already present when diabetes was diagnosed was tested as total number of comorbid diseases, and as presence of specific disease groups, i.e. cardiovascular, mental, and musculoskeletal disease, malignancies, and COPD. In subgroup effect analyses we tested if potential differences were modified by age, sex, socioeconomic status, and BMI.The number of comorbid diseases significantly influenced the SBP trend, with highest values after five years for diabetes patients without comorbidity (p = 0.005. The number of diseases did not influence the HbA1C trend (p = 0.075. Comorbid musculoskeletal disease resulted in lower HbA1C at the time of diabetes diagnosis, but in higher values after five years (p = 0.044. Patients with cardiovascular diseases had sustained elevated levels of SBP (p = 0.014. Effect modification by socioeconomic status was observed in some comorbidity subgroups.Presence of comorbidity in type 2 diabetes patients affected the long-term course of HbA1C and SBP in this primary care cohort. Numbers and types of comorbidity showed differential effects: not the simple sum of diseases, but specific types of comorbid disease had a negative influence on long-term diabetes control parameters. The complex interactions between comorbidity, diabetes control and effect modifiers require further investigation and may help to personalize treatment goals.

    In recent years, the number of randomized controlled trials (RCTs) in the field of orthopaedics is increasing in Mainland China. However, randomized controlled trials (RCTs) are inclined to bias if they lack methodological quality. Therefore, we performed a survey of RCT to assess: (1) What about the quality of RCTs in the field of orthopedics in Mainland China? (2) Whether there is difference between the core journals of the Chinese department of orthopedics and Orthopaedics Traumatology Surgery & Research (OTSR). This research aimed to evaluate the methodological reporting quality according to the CONSORT statement of randomized controlled trials (RCTs) in seven key orthopaedic journals published in Mainland China over 5 years from 2010 to 2014. All of the articles were hand researched on Chongqing VIP database between 2010 and 2014. Studies were considered eligible if the words "random", "randomly", "randomization", "randomized" were employed to describe the allocation way. Trials including animals, cadavers, trials published as abstracts and case report, trials dealing with subgroups analysis, or trials without the outcomes were excluded. In addition, eight articles selected from Orthopaedics Traumatology Surgery & Research (OTSR) between 2010 and 2014 were included in this study for comparison. The identified RCTs are analyzed using a modified version of the Consolidated Standards of Reporting Trials (CONSORT), including the sample size calculation, allocation sequence generation, allocation concealment, blinding and handling of dropouts. A total of 222 RCTs were identified in seven core orthopaedic journals. No trials reported adequate sample size calculation, 74 (33.4%) reported adequate allocation generation, 8 (3.7%) trials reported adequate allocation concealment, 18 (8.1%) trials reported adequate blinding and 16 (7.2%) trials reported handling of dropouts. In OTSR, 1 (12.5%) trial reported adequate sample size calculation, 4 (50.0%) reported adequate

    Malaria remains a major cause of febrile illness in Nigeria and interventions to reduce malaria burden in Nigeria focus on the use of insecticide-treated nets. This study determined the prevalence of malaria parasitaemia and the use of insecticide-treated nets (ITNs) for the control of malaria amongst under-five year old children in Calabar, Nigeria. A total of 270 under-5 year old children were recruited and structured questionnaires were used to obtain information on the background characteristics of the respondents from their caregivers. Capillary blood samples were collected from each of the patients through finger-pricking and tested for malaria parasites by Rapid Diagnostic Test and microscopy. An overall parasitaemia prevalence of 32.2% (by Rapid diagnostic test kit [RDT]) and 40.1% (by microscopy) were obtained in this study. Forty-six (45.5%) of the febrile patients had malaria parasitaemia (by RDT) or 41 (59.4%) by microscopy. One hundred and fifty (55.6%) of the caregivers acknowledged the use of nets on doors and windows for malaria prevention and control. One hundred and thirty-nine (51.5%) mentioned sleeping under mosquito net while 138 (51.1%) acknowledged the use of insecticide sprays. Although 191 (71.5%) of the households possessed at least one mosquito net, only 25.4% of the under-5 children slept under any net the night before the survey. No statistically significant reduction in malaria parasitaemia was observed with the use of mosquito nets among the under-5 children. Almost all the respondents (97.8%) identified mosquito bite as the cause of malaria. Fever was identified by the majority of the respondents (92.2%) as the most common symptom of malaria. The findings of the study showed high prevalence of parasitaemia and that fever was significantly associated with malaria parasitaemia. Mosquito net utilization among the under-fives was low despite high net ownership rate by households. Therefore, for effective control of malaria, public health

    Radiographic adaptations and changes in adult climbers are a well-known fact, but few data are available for young climbers. Radiographic adaptations have been shown for highly active young climbers. The question arises whether these adaptations may lead to an early onset of osteoarthrosis in the fingers. Cohort study; Level of evidence, 2. Ten members of the German Junior National Team (GJNT; 21.0 +/- 1.6 years) and 10 recreational climbers (RC; 19.9 +/- 1.9 years) were examined using a standard questionnaire and radiographs of the hand. For comparison, radiographs of 12 young nonclimbers (control group [CG]) were evaluated. The climbing level of GJNT increased significantly during the 5-year evaluation period (P climbing (P climbing competitions (P climbing level (2004) (P climbing leads to adaptive reactions such as cortical hypertrophy and broadened joint bases in the fingers. Nevertheless, osteoarthrotic changes are rare in young climbers. A longer follow-up is necessary to evaluate whether these adaptive stress reactions may lead to an early onset of osteoarthritis.

Artesunate + amodiaquine (ASAQ and artemether-lumefantrine (AL are respectively the first- and second-line treatments for uncomplicated falciparum malaria in Côte d'Ivoire. A comparison of the efficacy and safety of these two drug combinations was necessary to make evidence-based drug treatment policies. Methods: In an open-label, non inferiority, randomized, controlled clinical trial, children aged 6–59 months were randomized to receive ASAQ or AL. Both drug regimens were given for 3 days, and follow-up was for 28 days. The primary endpoint was the 28-day cure rates and was defined as proportion of patients with polymerase chain reaction (PCR-corrected cure rate after 28 days of follow-up. Findings: A total of 251 patients who were attending the Ayame and Dabakala hospitals and presenting with symptomatic acute uncomplicated falciparum malaria were randomized to receive ASAQ (128 and AL (123. The intention-to-treat analysis showed effectiveness rates of 94.5% and 93.5% for ASAQ and AL, respectively on day 28. After adjustment for PCR results, these rates were 96.1% and 96.8%, respectively. On day 28, the per-protocol analysis showed effectiveness rates of 98.4% and 96.6% for ASAQ and AL, respectively. After adjustment by PCR for reinfection, these rates were 100% for each drug, and both regimens were well tolerated. Conclusion: ASAQ and AL remain efficacious treatments of uncomplicated falciparum malaria in Ivorian children 5 years after adoption. The efficacy of ASAQ and AL in Côte d'Ivoire requires, therefore, continuous

    To address to burden of infectious diseases such as diarrhoea, the Vietnamese government has enacted the Law on Prevention and Control of Infectious Diseases (LPCIDs) since July 2008. However, no evaluation of the impact of the LPCID has been conducted. This study aims to evaluate the impact of the LPCID on diarrhoeal control for the 5 years following the implementation of LPCID in Vietnam. We used an interrupted time series design using a segmented regression analysis to estimate the 'province-level' impact of LPCID and then used random-effect meta-analysis to estimate the pooled effect sizes of the 'country-level' impact of LPCID on diarrhoeal control throughout Vietnam. The results show that the impacts varied by provinces. They were classified in four groups: 'positive impact, positive impact without sustainability, possibly positive impact, no or negative impact' of the LPCID. The meta-analysis indicated that the country-level impact of the LPCID became significant at 11 months after the LPCID took effect, with a decrease in level of diarrhoea of 9.7% (coefficient, -0.097; 95% CI: -19.1 to - 0.002) and a permanent downward trend of diarrhoea at a rate of 1.1% per month (coefficient, -0.011; 95% CI: -0.02 to - 0.003); whereas the trend in diarrhoea before the LPCID took effect was unchanging (coefficient, 0.002; 95% CI, 0-0.004). At 12, 24, 36, 48 and 60 months following the LPCID implementation date the levels of diarrhoea decreased by 10.9% (coefficient, -0.109; 95% CI: -0.203 to - 0.015), P < 0.01), 21.8% (coefficient, -0.218; 95% CI: -0.338 to - 0.098), P < 0.01), 31% (coefficient, -0.31; 95% CI: -0.474 to - 0.145), P < 0.01), 46.8% (coefficient, -0.468; 95% CI: -0.667 to - 0.27), P < 0.01), 48.2% (coefficient, -0.482; 95% CI: -0.708 to - 0.256), P < 0.01) respectively. The findings of this study reveal the effectiveness of the LPCID in reducing diarrhoea incidence in Vietnam. However, further studies should be conducted to

    The aim of this study was to determine inguinal hernia recurrence rates 5 years after endoscopic totally extraperitoneal (TEP) inguinal hernia repair when either lightweight or heavyweight mesh was used. Recurrence is an important complication of inguinal hernia surgery. Higher recurrence rates of Ultrapro lightweight meshes after TEP repair have been demonstrated, yet data regarding long-term follow-up are limited. From 2010 to 2012, 950 male adult patients with primary unilateral hernias were randomized to TEP hernia repair with heavyweight (Prolene) or lightweight (Ultrapro) mesh. Five years postoperatively, the validated PINQ-PHONE telephone questionnaire was carried out. Participants with a positive questionnaire reply were scheduled for a clinical visit. A recurrence was defined as a clinically detectable bulge in the operated groin on physical examination. Data on development of recurrence could be obtained from 790 patients (83.2% 5-year follow-up rate). Four patients presented with a recurrence at the outpatient clinic between 2 and 5 years postoperatively. Thirty-five patients (4.6%) with a positive PINQ-PHONE reply (60.0% lightweight vs 40.0% heavyweight) were physically examined at the outpatient clinic. In 2 patients (lightweight) a recurrence was detected. The total 5-year recurrence rate after TEP hernia repair was 2.4% (3.8% lightweight, 1.1% heavyweight, P = 0.01). A significantly higher recurrence rate for lightweight mesh in primary direct hernias was found (P = 0.003). The overall recurrence rate 5 years after TEP repair was low. Ultrapro lightweight meshes showed higher recurrence rates than heavyweight meshes and are not recommended for endoscopic TEP inguinal hernia repair.

    To compare risk of stunting at 5 years across etiological subgroups of small for gestational age (SGA) newborns. We analyzed data of a subsample (N = 1100) of the Early Childhood Longitudinal Study-Birth Cohort. We defined SGA as birth weight SGA subgroups, adjusting for confounders. SGA subgroup with maternal short stature (odds ratio [OR] = 3.88; 95% confidence interval [CI] = 2.16-6.96) or inadequate GWG (OR = 2.18; 95% CI = 1.23-3.84) had higher risk of stunting at 5 years, compared with the SGA subgroup without the corresponding risk factor. SGA newborns with both maternal smoking and inadequate GWG during pregnancy had much higher risk of stunting at 5 years (OR = 3.10; 95% CI = 1.21-7.91), compared with SGA newborns without any of these 2 SGA risk factors. Etiological subgroups of SGA differed in risk of stunting at 5 years. SGA newborns of inadequate GWG mothers who smoke and SGA newborns of short mothers were at particularly high risk of stunting.

    The effectiveness of intermittent montelukast for wheeze in young children is unclear. We aimed to assess whether intermittent montelukast is better than placebo for treatment of wheeze in this age group. Because copy numbers of the Sp1-binding motif in the arachidonate 5-lipoxygenase (ALOX5) gene promoter (either 5/5, 5/x, or x/x, where x does not equal 5) modifies response to montelukast in adults, we stratified by this genotype. We did this multicentre, parallel-group, randomised, placebo-controlled trial between Oct 1, 2010, and Dec 20, 2013, at 21 primary care sites and 41 secondary care sites in England and Scotland. Children aged 10 months to 5 years with two or more wheeze episodes were allocated to either a 5/5 or 5/x+x/x ALOX5 promoter genotype stratum, then randomly assigned (1:1) via a permuted block schedule (size ten), to receive intermittent montelukast or placebo given by parents at each wheeze episode over a 12 month period. Clinical investigators and parents were masked to treatment group and genotype strata. The primary outcome was number of unscheduled medical attendances for wheezing episodes. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT01142505. We randomly assigned 1358 children to receive montelukast (n=669) or placebo (n=677). Consent was withdrawn for 12 (1%) children. Primary outcome data were available for 1308 (96%) children. There was no difference in unscheduled medical attendances for wheezing episodes between children in the montelukast and placebo groups (mean 2·0 [SD 2·6] vs 2·3 [2·7]; incidence rate ratio [IRR] 0·88, 95% CI: 0·77-1·01; p=0·06). Compared with placebo, unscheduled medical attendances for wheezing episodes were reduced in children given montelukast in the 5/5 stratum (2·0 [2·7] vs 2·4 [3·0]; IRR 0·80, 95% CI 0·68-0·95; p=0·01), but not in those in the 5/x+x/x stratum (2·0 [2·5] vs 2·0 [2·3]; 1·03, 0·83-1·29; p=0·79, pinteraction=0·08).

    Endovenous laser ablation (EVLA) has been demonstrated to be an effective treatment for lower limb varicose veins in the short and midterm results. This study reports the 5-year outcomes of EVLA technique at different power settings. Patients with primary symptomatic, unilateral varicose veins secondary to saphenofemoral junction (SFJ) incompetence and great saphenous vein (GSV) reflux were recruited and randomized to either 12W (intermittent laser withdrawal) or 14W (continuous laser withdrawal). They were assessed at baseline, 1, 6, 12, 52, 104 weeks, and 5 years. Outcome measures included: Venous Clinical Severity Score (VCSS), pain scores, time taken to return to normal functions, complications, recurrence, quality of life (QoL), and duplex ultrasound findings. 76 consecutive patients, M: F 30:46, median age 54(IQR: 37.3-59) years were randomized. Intragroup analysis: Significant improvement was seen in both groups in VCSS, pain scores, Aberdeen varicose vein questionnaire (AVVQ) scores, Shortform-36 (SF-36) and Euroqol (EQ-5D) domains over the follow-up period (P 0.05). Late outcomes following EVLA were superior for the 14W continuous power settings achieving better long term venous occlusion and lowered recurrence rates without increasing post-operative morbidity. Hence 14W continuous setting should be the energy delivery mode of choice.

    To date, there are no reports of intraoperative radiotherapy (IORT) use with long-term follow up as a method of accelerated partial breast irradiation (APBI) in Asian countries. We initiated a prospective phase I/II clinical trial of IORT in Japan in 2007, and herein, we report the 5-year follow-up results. The following inclusion criteria were used for enrollment in the trial: (1) tumor size surgery, (3) age >50 years, and (4) negative margins after resection. In February 2009, the eligibility criteria were changed to include only patients with sentinel lymph node-negative disease. In phase I, the radiotherapy dose was escalated from 19 Gy/fr to 21 Gy/fr, incremented by 1 Gy per step, with 3 patients in each step. Doses were escalated after all patients in the preceding cohort had completed treatment and exhibited only grade 1 or 2 toxicities at a given dose level. The recommended phase II dose was set at 21 Gy at 90 % isodose. The primary endpoint was early toxicity. Secondary endpoints were long-term efficacy and late toxicity. In addition, Hypertrophic scarring was evaluated retrospectively as a cosmetic outcome by a radiation oncologist. Between December 2007 and March 2010, 32 women with breast cancer were enrolled in the trial. The median age was 65 years (51-80 years), and the median follow-up time was 6 years. No recurrence or metastasis was observed in any patient. Grade 2 fibrosis was detected in 3 patients as an acute adverse event and in 2 patients as a late adverse event. Ten patients developed a hypertrophic scar 1 year after the IORT; the number of patients decreased to 7 in the 3 years of follow-up. The first group of female Asian patients tolerated the treatment with IORT in this Phase I/II study and remained recurrence-free for more than 5 years after treatment. However, 24 % of the patients developed hypertrophic scarring, an event that is being further examined in our ongoing multi-center Phase II trial of IORT for early breast cancer.

    The problem of controlling the longitudinal motion of front-wheels electric vehicle (EV) is considered making the focus on the case where a single dc motor is used for both front wheels. Chassis dynamics are modelled applying relevant fundamental laws taking into account the aerodynamic effects and the road slope variation. The longitudinal slip, resulting from tire deformation, is captured through Kiencke's model. Despite its highly nonlinear nature the complete model proves to be utilizable in longitudinal control design. The control objective is to achieve a satisfactory vehicle speed regulation in acceleration/deceleration stages, despite wind speed and other parameters uncertainty. An adaptive controller is developed using the backstepping design technique. The obtained adaptive controller is shown to meet its objectives in presence of the changing aerodynamics efforts and road slope.

    The aim of this study was to evaluate the 5 year clinical dentin bonding effectiveness of two HEMA-free adhesives in Class V non-carious cervical lesions. A total of 169 Class V restorations were placed in 67 patients with a self-etching adhesive (G-Bond; 67), a 3-step HEMA and TEGDMA free etch-and-rinse (cfm; 51) and a control HEMA-containing etch-and-rinse adhesive (XP Bond; 51) in non-carious cervical lesions without intentional enamel involvement. The restorations were evaluated at baseline and yearly during a 5 year follow-up with modified USPHS criteria. Dentin bonding efficiency was determined by the percentage of lost restorations. During the 5 years, 159 restorations could be evaluated. Good short time dentin retention was observed for the three adhesives, there all adhesives fulfilled at 18 months the full acceptance ADA criteria. At 5 years a cumulative number of 22 lost restorations (13.8%) was observed. The HEMA-free adhesives showed significantly higher dentin retention compared to the HEMA-containing one. Loss of retention was observed for 5 G-Bond (7.9%), 4 cfm (8.3%) and 13 XP Bond (27.1%) restorations (padhesives was successful after 5 years. Despite concerns which have been raised, showed the 1-step SEA one of the best reported clinical dentin bonding effectiveness. Copyright © 2013 Academy of Dental Materials. Published by Elsevier Ltd.

Intensity-modulated radiotherapy (IMRT) has the theoretical advantage of a further increase in dose conformity compared with three-dimensional techniques, with more normal tissue sparing. The aim of this randomised trial is to compare the local recurrence and survival of APBI using the IMRT technique after breast-conserving surgery to conventional whole-breast irradiation (WBI) in early stage BC. This study was performed at the University of Florence (Florence, Italy). Women aged more than 40years affected by early BC, with a maximum pathological tumour size of 25mm, were randomly assigned in a 1:1 ratio to receive either WBI or APBI using IMRT. Patients in the APBI arm received a total dose of 30 Gy to the tumour bed in five daily fractions. The WBI arm received 50Gy in 25 fractions, followed by a boost on the tumour bed of 10Gy in five fractions. The primary end-point was occurrence of ipsilateral breast tumour recurrences (IBTRs); the main analysis was by intention-to-treat. This trial is registered with ClinicalTrials.gov, number NCT02104895. A total of 520 patients were randomised (260 to external WBI and 260 to APBI with IMRT) between March 2005 and June 2013. At a median follow-up of 5.0 years (Interquartile Range (IQR) 3.4-7.0), the IBTR rate was 1.5% (three cases) in the APBI group (95% confidence interval (CI) 0.1-3.0) and in the WBI group (three cases; 95% CI 0.0-2.8). No significant difference emerged between the two groups (log rank test p=0.86). We identified seven deaths in the WBI group and only one in the APBI group (p=0.057). The 5-year overall survival was 96.6% for the WBI group and 99.4% for the APBI group. The APBI group presented significantly better results considering acute (p=0.0001), late (p=0.004), and cosmetic outcome (p=0.045). To our knowledge, this is the first randomised

    Background There are very limited data on children with pneumonia in Mali. The objective was to assess the etiology and factors associated with community-acquired pneumonia in hospitalized children pneumonia; Controls were hospitalized children without respiratory features, matched for age and period. Respiratory specimens, were collected to identify 19 viruses and 5 bacteria. Whole blood was collected from cases only. Factors associated with pneumonia were assessed by multivariate logistic regression. Results Overall, 118 cases and 98 controls were analyzed; 44.1% were female, median age was 11 months. Among pneumonia cases, 30.5% were hypoxemic at admission, mortality was 4.2%. Pneumonia cases differed from the controls regarding clinical signs and symptoms but not in terms of past medical history. Multivariate analysis of nasal swab findings disclosed that S. pneumoniae (adjusted odds ratio [aOR] = 3.4, 95% confidence interval [95% CI]: 1.6–7.0), human metapneumovirus (aOR = 17.2, 95% CI: 2.0–151.4), respiratory syncytial virus [RSV] (aOR = 7.4, 95% CI: 2.3–23.3), and influenza A virus (aOR = 10.7, 95% CI: 1.0–112.2) were associated with pneumonia, independently of patient age, gender, period, and other pathogens. Distribution of S. pneumoniae and RSV differed by season with higher rates of S. pneumoniae in January-June and of RSV in July-September. Pneumococcal serotypes 1 and 5 were more frequent in pneumonia cases than in the controls (P = 0.009, and P = 0.04, respectively). Conclusions In this non-PCV population from Mali, pneumonia in children was mainly attributed to S. pneumoniae, RSV, human metapneumovirus, and influenza A virus. Increased pneumococcal conjugate vaccine coverage in children could significantly reduce the burden of pneumonia in sub-Saharan African countries. PMID:26696249

    Using longitudinal data for adult women from the National Longitudinal Surveys of Labor Market Experience, this study examined the relation between getting divorced and changes in the individual's locus of control orientation. The sample contained 1,814 white women ages 32-46 years who were in their first marriage in 1969. Marital status and locus of control (an 11-item abbreviated version of Rotter's Internal-External Locus of Control Scale) were measured in 1969, 1972, and 1977. Based on previous literature on locus of control and life events and on divorce, stress, and mental health, the author hypothesized that divorced people, in comparison with those who remained married, would show a short-term increase in externality from 1969-1972, followed by a return over the next 5 years to levels of locus of control comparable to that of the group who remained married. It was also hypothesized that locus of control scores would not predict the likelihood of becoming divorced over the 8-year period. All three hypotheses were confirmed. The findings were discussed in the context of two larger theoretical issues: the influence of important life events on locus of control and the causal direction in the well-documented association between divorce and mental health.

    In a previously published randomized controlled trial (Brown et al. Alcohol Clin Exp Res 2010; 34, 292-301), our research team showed that a 30-minute brief motivational interviewing (BMI) session was more effective in reducing percentages of risky drinking days in drunk driving recidivists than a control information-advice intervention at 12-month follow-up. In this sequel to the initial study, 2 main hypotheses were tested: (i) exposure to BMI increases the time to further arrests and crashes compared with exposure to the control intervention (CTL) and (ii) characteristics, such as age, moderate the benefit of BMI. A sample of 180 community-recruited recidivists who had drinking problems participated in the study. Participants gave access to their provincial driving records at baseline and were followed up for a mean of 1,684.5 days (SD = 155.7) after randomization to a 30-minute BMI or CTL session. Measured outcomes were driving arrests followed by convictions including driving while impaired (DWI), speeding, or other moving violations as well as crashes. Age, readiness to change alcohol consumption, alcohol misuse severity, and number of previous DWI convictions were included as potential moderators of the effect of the interventions. For arrests, Cox proportional hazards modeling revealed no significant differences between the BMI and the CTL group. When analyses were adjusted to age tertile categories, a significant effect of BMI in the youngest age tertile (<43 years old) emerged. For crashes, no between-group differences were detected. BMI was better at delaying DWI and other dangerous traffic violations in at-risk younger drivers compared with a CTL similar to that provided in many remedial programs. BMI may be useful as an opportunistic intervention for DWI recidivism prevention in settings such as DWI courts. Treatment effectiveness studies are needed to ascertain how the present findings generalize to the real-world conditions of mandated

    Project Energize, a region-wide whole-school nutrition and physical activity programme, commenced as a randomised controlled trial (RCT) in the period 2004-6 in 124 schools in Waikato, New Zealand. In 2007, sixty-two control schools were engaged in the programme, and by 2011, all but two of the 235 schools in the region were engaged. Energizers (trained nutrition and physical activity specialists) work with eight to twelve schools each to achieve the goals of the programme, which are based on healthier eating and enhanced physical activity. In 2011, indices of obesity and physical fitness of 2474 younger (7·58 (sd 0·57) years) and 2330 older (10·30 (sd 0·51) years) children attending 193 of the 235 primary schools were compared with historical measurements. After adjusting for age, sex, ethnicity, socio-economic status (SES) and school cluster effects, the combined prevalence of obesity and overweight among younger and older children in 2011 was lower by 31 and 15 %, respectively, than that among 'unEnergized' children in the 2004 to 2006 RCT. Similarly, BMI was lower by 3·0 % (95 % CI - 5·8, - 1·3) and 2·4 % (95 % CI - 4·3, - 0·5). Physical fitness (time taken to complete a 550 m run) was significantly higher in the Energized children (13·7 and 11·3 %, respectively) than in a group of similarly aged children from another region. These effects were observed for boys and girls, both indigenous Māori and non-Māori children, and across SES. The long-term regional commitment to the Energize programme in schools may potentially lead to a secular reduction in the prevalence of overweight and obesity and gains in physical fitness, which may reduce the risk of developing obesity and type 2 diabetes.

    The aim of this study was to compare the 5-year outcomes of glass fiber composite with cast posts and cores for the restoration of endodontically treated teeth. A total of 143 patients in need of 203 full ceramic restorations on endodontically treated teeth were included. After primary stratification based on the need for post or no post, teeth were randomly allotted to test group 1 (prefabricated glass fiber posts), 2 (custom-made glass fiber posts), or 3 (composite cores without posts). The control group was treated with gold alloy-based wrought posts and cast cores. Success (original present) and survival (present after intervention) probability lifetime curves, corrected for clustering, were drawn over the entire data set. The mean follow-up time was 5.8 years (range: 0.5 to 7.2 years). At 5 years, the success and survival probabilities were 85.2% and 91.5%, respectively. Lifetime curves did not show any significant differences between the test and control groups for success (P = .85) or survival (P = .57). Moreover, no significant differences for success or survival could be found among the four groups (the three test groups and the control group). After 5 years of follow-up, cast gold and composite post-and-core systems on teeth with ceramic full restorations provided with a ferrule performed equally well.

    Studies on midterm outcomes of the arthroscopic treatment of femoroacetabular impingement (FAI) and labral tears with mild osteoarthritis (OA) are limited. To evaluate outcomes of the arthroscopic treatment of FAI and labral tears in patients with mild preoperative OA (Tönnis grade 1) at a minimum 5-year follow-up, and to perform a matched-pair comparison to a control group with Tönnis grade 0. Cohort study; Level of evidence, 3. Data were prospectively collected on patients who underwent hip arthroscopic surgery between February 2008 and April 2011. Inclusion criteria were arthroscopic treatment for FAI and labral tears and having preoperative patient-reported outcome (PRO) scores, including the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), and Hip Outcome Score-Sports-Specific Subscale (HOS-SSS), and visual analog scale (VAS) scores for pain. Exclusion criteria were workers' compensation claims, preoperative Tönnis grade ≥2, and previous hip conditions (ipsilateral surgery, slipped capital femoral epiphysis, avascular necrosis, and dysplasia). Patients with minimum 5-year outcomes were eligible for matching on a 1:1 ratio (Tönnis grade 0 vs 1) based on age ±5 years, body mass index ±5 kg/m2, sex, labral treatment, and capsular treatment. Of 356 eligible hips, 292 hips had minimum 5-year outcomes (82%). Eighty-five hips with Tönnis grade 1 were evaluated. At 5-year follow-up, patients with Tönnis grade 1 had significant improvements in all PRO and VAS scores ( P arthroscopic treatment of FAI and labral tears in patients with Tönnis grade 1 had good results at 5-year follow-up. After controlling for other variables using a matched-pair comparison, patients with Tönnis grade 1 had similar, durable improvements to those with Tönnis grade 0. While strict surgical indications and appropriate expectations are recommended for patients with mild OA, Tönnis grade 1 alone should not be considered a contraindication to hip arthroscopic

    The etiology of chronic prostatitis chronic pelvic pain syndrome (CP/CPPS) is still unclear. As no pathological findings exist the diagnosis of CP/CPPS is essentially a diagnosis by exclusion and functional disorders, so-called somatoform disorders play a more important role. Osteopathy treats functional disorders of the musculoskeletal system including all associated internal organs but little attention has so far been paid to this treatment method. Therefore, the 5-year follow-up period was intended to show that this is a sustainable form of therapy using exclusively manual and gentle techniques and simple treatment procedures resulting in manageable costs. The aim of this study was to investigate whether sustainability of osteopathic treatment could be demonstrated even after 5 years. This was a randomized controlled study initially involving 5 treatment sessions, a follow-up without treatment after 6 weeks and further follow-up after 1.5 and 5 years. Of the 20 patients 19 in the test group participated in the 5-year follow-up. The control group were not asked because it would have been unacceptable to expect the patients to refrain from having treatment for as long as 5 years. The men were aged between 29 and 70 years. The patients were asked to complete the international prostate symptom score (IPSS), the National Institutes of Health chronic prostatitis symptom index (NIH-CPSI) and the quality of life (QOL) questionnaires once again and in particular to state whether they had received osteopathic treatment specifically for the prostate problem and how often they had been treated. The follow-up assessment of the symptoms of chronic prostatitis (NIH-CPSI) showed that they had further improved after 1.5 years (intragroup difference -1.8 points, 95 % confidence interval CI=-3.8 to 0.3) and also after 5 years (intragroup difference -1.3 points 95 % CI=-3.4 to 0.8). The urinary tract symptoms (IPSS) showed a statistically significant improvement (intergroup

  18. Fuzzy Logic Decoupled Longitudinal Control for General Aviation Airplanes

    It has been hypothesized that a human pilot uses the same set of generic skills to control a wide variety of aircraft. If this is true, then it should be possible to construct an electronic controller which embodies this generic skill set such that it can successfully control difference airplanes without being matched to a specific airplane. In an attempt to create such a system, a fuzzy logic controller was devised to control throttle position and another to control elevator position. These two controllers were used to control flight path angle and airspeed for both a piston powered single engine airplane simulation and a business jet simulation. Overspeed protection and stall protection were incorporated in the form of expert systems supervisors. It was found that by using the artificial intelligence techniques of fuzzy logic and expert systems, a generic longitudinal controller could be successfully used on two general aviation aircraft types that have very difference characteristics. These controllers worked for both airplanes over their entire flight envelopes including configuration changes. The controllers for both airplanes were identical except for airplane specific limits (maximum allowable airspeed, throttle lever travel, etc.). The controllers also handled configuration changes without mode switching or knowledge of the current configuration. This research validated the fact that the same fuzzy logic based controller can control two very different general aviation airplanes. It also developed the basic controller architecture and specific control parameters required for such a general controller.

    Short-term stability after revision total knee arthroplasty (TKA) with either fully cemented or hybrid-placed implants is comparable. Interestingly, implant micromotion >1 mm/degree occurred with both techniques which might increase the risk of loosening in the midterm or long-term. Therefore, the present study investigated midterm stability and clinical results of fully cemented vs hybrid-placed revision TKA, with mild to moderate bone loss, using radiostereometric analysis (RSA). This study involves the prolonged follow-up of a previous randomized controlled trial. RSA images taken at baseline, 6 weeks, 3 and 6 months, and 1, 2 and 6.5 years of follow-up were analyzed. Stability of the femoral and tibial implants was evaluated using total translation and rotation, based on the micromotion determined with model-based RSA. Of the 30 patients who completed the 2-year follow-up in the original randomized controlled trial, 23 (12 cement, 11 hybrid) were available for follow-up at 6.5-year (range 5.4-7.3). There were no differences in median total translation and rotation of the femoral and tibial components between the 2 groups, and none of the clinical scores differed between the groups. Interestingly, in the group with cemented stems, 5 tibia implants showed >1 mm/degree micromotion compared to none in the hybrid group. There was no difference in median micromotion and clinical outcome between fully cemented and hybrid-placed revision TKA 6.5 years postoperatively. Two femur components showed progressive migration over time whereas tibia components migrate especially in the first year followed by a stable situation. Whether this will lead to loosening and re-revisions remains to be investigated. Copyright © 2016 Elsevier Inc. All rights reserved.

    WHO estimates exposure to air pollution from cooking with solid fuels is associated with over 4 million premature deaths worldwide every year including half a million children under the age of 5 years from pneumonia. We hypothesised that replacing open fires with cleaner burning biomass-fuelled cookstoves would reduce pneumonia incidence in young children. We did a community-level open cluster randomised controlled trial to compare the effects of a cleaner burning biomass-fuelled cookstove intervention to continuation of open fire cooking on pneumonia in children living in two rural districts, Chikhwawa and Karonga, of Malawi. Clusters were randomly allocated to intervention and control groups using a computer-generated randomisation schedule with stratification by site, distance from health centre, and size of cluster. Within clusters, households with a child under the age of 4·5 years were eligible. Intervention households received two biomass-fuelled cookstoves and a solar panel. The primary outcome was WHO Integrated Management of Childhood Illness (IMCI)-defined pneumonia episodes in children under 5 years of age. Efficacy and safety analyses were by intention to treat. The trial is registered with ISRCTN, number ISRCTN59448623. We enrolled 10 750 children from 8626 households across 150 clusters between Dec 9, 2013, and Feb 28, 2016. 10 543 children from 8470 households contributed 15 991 child-years of follow-up data to the intention-to-treat analysis. The IMCI pneumonia incidence rate in the intervention group was 15·76 (95% CI 14·89-16·63) per 100 child-years and in the control group 15·58 (95% CI 14·72-16·45) per 100 child-years, with an intervention versus control incidence rate ratio (IRR) of 1·01 (95% CI 0·91-1·13; p=0·80). Cooking-related serious adverse events (burns) were seen in 19 children; nine in the intervention and ten (one death) in the control group (IRR 0·91 [95% CI 0·37-2·23]; p=0·83). We found no evidence that an

    The Roux-en-Y gastric bypass is effective in achieving established diabetes treatment targets, but durability is unknown. To compare durability of Roux-en-Y gastric bypass added to intensive lifestyle and medical management in achieving diabetes control targets. Observational follow-up of a randomized clinical trial at 4 sites in the United States and Taiwan, involving 120 participants who had a hemoglobin A1c (HbA1c) level of 8.0% or higher and a body mass index between 30.0 and 39.9 (enrolled between April 2008 and December 2011) were followed up for 5 years, ending in November 2016. Lifestyle-intensive medical management intervention based on the Diabetes Prevention Program and LookAHEAD trials for 2 years, with and without (60 participants each) Roux-en-Y gastric bypass surgery followed by observation to year 5. The American Diabetes Association composite triple end point of hemoglobin A1c less than 7.0%, low-density lipoprotein cholesterol less than 100 mg/dL, and systolic blood pressure less than 130 mm Hg at 5 years. Of 120 participants who were initially randomized (mean age, 49 years [SD, 8 years], 72 women [60%]), 98 (82%) completed 5 years of follow-up. Baseline characteristics were similar between groups: mean (SD) body mass index 34.4 (3.2) for the lifestyle-medical management group and 34.9 (3.0) for the gastric bypass group and had hemoglobin A1c levels of 9.6% (1.2) and 9.6% (1.0), respectively. At 5 years, 13 participants (23%) in the gastric bypass group and 2 (4%) in the lifestyle-intensive medical management group had achieved the composite triple end point (difference, 19%; 95% CI, 4%-34%; P = .01). In the fifth year, 31 patients (55%) in the gastric bypass group vs 8 (14%) in the lifestyle-medical management group achieved an HbA1c level of less than 7.0% (difference, 41%; 95% CI, 19%-63%; P = .002). Gastric bypass had more serious adverse events than did the lifestyle-medical management intervention, 66 events vs 38 events, most

    Even small design modifications of uncemented hip stems may alter the postoperative 3-D migration pattern. The Furlong Active is an uncemented femoral stem which, in terms of design, is based on its precursor-the well-proven Furlong HAC-but has undergone several design changes. The collar has been removed on the Active stem along with the lateral fin; it is shorter and has more rounded edges in the proximal part. We compared the migration patterns of the uncemented Furlong HAC stem and the modified Furlong Active stem in a randomized, controlled trial over 5 years using radiostereometry (RSA). 50 patients with primary osteoarthritis were randomized to receive either the HAC stem or the Active stem. The patients underwent repeated RSA examinations (postoperatively, at 3 months, and after 1, 2, and 5 years) and conventional radiography, and they also filled out hip-specific questionnaires. During the first 3 months, the collarless Active stem subsided to a greater extent than the collar-fitted HAC stem (0.99 mm vs. 0.31 mm, p=0.05). There were, however, no other differences in movement measured by RSA or in clinical outcome between the 2 stems. After 3 months, both stem types had stabilized and almost no further migration was seen. The Active stem showed no signs of unfavorable migration. Our results suggest that the osseointegration is not compromised by the new design features.

    Experiments of synchrotron injection using the direct fast chopped H{sup -} beam extracted from a surface-plasma-type H{sup -} ion source has been successfully achieved. The injection phase of the fast chopped beam from linac into the booster synchrotron is adjustable to the center of rf bucket by using this beam. It was obtained that the longitudinal emittance was controlled at the extraction of the booster synchrotron, and that the beam loss during the injection into main ring of the KEK-PS was reduced by this fast chopped beam.

    Dengue Fever presents a significant and growing burden of disease to endemic countries, where children are at particular risk. Worldwide, no effective anti-viral treatment has been identified, thus vector control is key for disease prevention, particularly in Peru where no vaccine is currently available. This qualitative study aimed to explore the perceptions of dengue control in caregivers' of children under 5 years in Peru, to help direct future mosquito control programmes and strategy. Eighteen semi-structured interviews were conducted in one health centre in Iquitos, Peru. Interviews were audio-recorded, transcribed and translated by an independent translator. Data were analysed using an inductive thematic approach. Three core analytic themes were interpreted: (1) awareness of dengue and its control, (2) perceived susceptibility of children, rural riverside communities and city inhabitants, and (3) perceived responsibility of vector control. Participants were aware of dengue symptoms, transmission and larvae eradication strategies. Misconceptions about the day-time biting behaviour of the Aedes aegypti mosquito and confusion with other mosquito-borne diseases influenced preventative practice. Community-wide lack of cooperation was recognised as a key barrier. This was strengthened by attitudes that the government or health centre were responsible for dengue control and a belief that the disease cannot be prevented through individual actions. Participants felt powerless to prevent dengue due to assumed inevitability of infection and lack of faith in preventative practices. However, children and rural communities were believed to be most vulnerable. Perceptions of dengue control amongst caregivers to under 5's were important in shaping their likelihood to participate in preventative practices. There is a need to address the perceived lack of community cooperation through strategies creating a sense of ownership of community control and enhancing social

In this double-blind, randomized controlled efficacy trial, 276 nonpregnant, nonlactating women (18-45 years of age) and their families in Prey Veng, Cambodia, were randomized to receive 1 of 3 fish sauce formulations: low thiamin concentration (low, 2 g/L), high thiamin concentration (high, 8 g/L), or a control (no thiamin) fish sauce. Baseline (t = 0) and endline (t = 6 months) eTDP were measured with the use of high-performance liquid chromatography with a fluorescence detector. Fish sauce consumption did not differ between treatment groups (P = .19). In intent-to-treat analysis, women's baseline-adjusted endline eTDP (mean; 95% CI) was higher among women in the low (259; 245-274 nmol/L) and high (257; 237-276 nmol/L) groups compared with control (184; 169-198 nmol/L; P sauce appears to be an efficacious means of improving biochemical thiamin status in nonpregnant, nonlactating women and their children (1-5 years of age) living in rural Cambodia.

    Although evidence suggests cannabis impairs driving, its driving-performance effects are not fully characterized. We aimed to establish cannabis' effects on driving longitudinal control (with and without alcohol, drivers' most common drug combination) relative to psychoactive ∆(9) -tetrahydrocannabinol (THC) blood concentrations. Current occasional (≥1×/last 3 months, ≤3 days per week) cannabis smokers drank placebo or low-dose alcohol, and inhaled 500 mg placebo, low (2.9%), or high (6.7%) THC vaporized cannabis over 10 min ad libitum in separate sessions (within-subject, six conditions). Participants drove (National Advanced Driving Simulator, University of Iowa) simulated drives 0.5-1.3 h post-inhalation. Blood and breath alcohol samples were collected before (0.17 and 0.42 h) and after (1.4 and 2.3 h) driving. We evaluated the mean speed (relative to limit), standard deviation (SD) of speed, percent time spent >10% above/below the speed limit (percent speed high/percent speed low), longitudinal acceleration, and ability to maintain headway relative to a lead vehicle (headway maintenance) against blood THC and breath alcohol concentrations (BrAC). In N=18 completing drivers, THC was associated with a decreased mean speed, increased percent speed low and increased mean following distance during headway maintenance. BrAC was associated with increased SD speed and increased percent speed high, whereas THC was not. Neither was associated with altered longitudinal acceleration. A less-than-additive THC*BrAC interaction was detected in percent speed high (considering only non-zero data and excluding an outlying drive event), suggesting cannabis mitigated drivers' tendency to drive faster with alcohol. Cannabis was associated with slower driving and greater headway, suggesting a possible awareness of impairment and attempt to compensate. Copyright © 2016 John Wiley & Sons, Ltd.

    ExteNET showed that 1 year of neratinib, an irreversible pan-HER tyrosine kinase inhibitor, significantly improves 2-year invasive disease-free survival after trastuzumab-based adjuvant therapy in women with HER2-positive breast cancer. We report updated efficacy outcomes from a protocol-defined 5-year follow-up sensitivity analysis and long-term toxicity findings. In this ongoing randomised, double-blind, placebo-controlled, phase 3 trial, eligible women aged 18 years or older (≥20 years in Japan) with stage 1-3c (modified to stage 2-3c in February, 2010) operable breast cancer, who had completed neoadjuvant and adjuvant chemotherapy plus trastuzumab with no evidence of disease recurrence or metastatic disease at study entry. Patients who were eligible patients were randomly assigned (1:1) via permuted blocks stratified according to hormone receptor status (hormone receptor-positive vs hormone receptor-negative), nodal status (0 vs 1-3 vs or ≥4 positive nodes), and trastuzumab adjuvant regimen (given sequentially vs concurrently with chemotherapy), then implemented centrally via an interactive voice and web-response system, to receive 1 year of oral neratinib 240 mg/day or matching placebo. Treatment was given continuously for 1 year, unless disease recurrence or new breast cancer, intolerable adverse events, or consent withdrawal occurred. Patients, investigators, and trial funder were masked to treatment allocation. The predefined endpoint of the 5-year analysis was invasive disease-free survival, analysed by intention to treat. ExteNET is registered with ClinicalTrials.gov, number NCT00878709, and is closed to new participants. Between July 9, 2009, and Oct 24, 2011, 2840 eligible women with early HER2-positive breast cancer were recruited from community-based and academic institutions in 40 countries and randomly assigned to receive neratinib (n=1420) or placebo (n=1420). After a median follow-up of 5·2 years (IQR 2·1-5·3), patients in the neratinib

    Full Text Available Dengue Fever presents a significant and growing burden of disease to endemic countries, where children are at particular risk. Worldwide, no effective anti-viral treatment has been identified, thus vector control is key for disease prevention, particularly in Peru where no vaccine is currently available. This qualitative study aimed to explore the perceptions of dengue control in caregivers' of children under 5 years in Peru, to help direct future mosquito control programmes and strategy.Eighteen semi-structured interviews were conducted in one health centre in Iquitos, Peru. Interviews were audio-recorded, transcribed and translated by an independent translator. Data were analysed using an inductive thematic approach.Three core analytic themes were interpreted: (1 awareness of dengue and its control, (2 perceived susceptibility of children, rural riverside communities and city inhabitants, and (3 perceived responsibility of vector control. Participants were aware of dengue symptoms, transmission and larvae eradication strategies. Misconceptions about the day-time biting behaviour of the Aedes aegypti mosquito and confusion with other mosquito-borne diseases influenced preventative practice. Community-wide lack of cooperation was recognised as a key barrier. This was strengthened by attitudes that the government or health centre were responsible for dengue control and a belief that the disease cannot be prevented through individual actions. Participants felt powerless to prevent dengue due to assumed inevitability of infection and lack of faith in preventative practices. However, children and rural communities were believed to be most vulnerable.Perceptions of dengue control amongst caregivers to under 5's were important in shaping their likelihood to participate in preventative practices. There is a need to address the perceived lack of community cooperation through strategies creating a sense of ownership of community control and enhancing

    Full Text Available ABSTRACT BACKGROUND AND OBJECTIVES: To determine the incidence of signs and symptoms of temporomandibular disorder in elective surgery patients who underwent orotracheal intubation. METHODS: This was a longitudinal controlled study with two groups. The study group included patients who underwent orotracheal intubation and a control group. We used the American Academy of Orofacial Pain questionnaire to assess the temporomandibular disorder signs and symptoms one-day postoperatively (T1, and the patients' baseline status prior to surgery (T0 was also recorded. The same questionnaire was used after three months (T2. The mouth opening amplitude was measured at T1 and T2. We considered a pvalue of less than 0.05 to be significant. RESULTS: We included 71 patients, with 38 in the study group and 33 in the control. There was no significant difference between the groups in age (study group: 66.0 [52.5-72.0]; control group: 54.0 [47.0-68.0]; p = 0.117 or in their belonging to the female gender (study group: 57.9%; control group: 63.6%; p = 0.621. At T1, there were no statistically significant differences between the groups in the incidence of mouth opening limitation (study group: 23.7% vs. control group: 18.2%;p = 0.570 or in the mouth opening amplitude (study group: 45.0 [40.0-47.0] vs. control group: 46.0 [40.0-51.0];p = 0.278. At T2 we obtained similar findings. There was no significant difference in the affirmative response to all the individual questions in the American Academy of Orofacial Pain questionnaire. CONCLUSIONS: In our population, the incidence of signs and symptoms of temporomandibular disorder of muscular origin was not different between the groups.

    Selenium and coenzyme Q10 are essential for the cell. Low cardiac contents of selenium and coenzyme Q10 have been shown in patients with cardiomyopathy, but inconsistent results are published on the effect of supplementation of the two components separately. A vital relationship exists between the two substances to obtain optimal function of the cell. However, reports on combined supplements are lacking. A 5-year prospective randomized double-blind placebo-controlled trial among Swedish citizens aged 70 to 88 was performed in 443 participants given combined supplementation of selenium and coenzyme Q10 or a placebo. Clinical examinations, echocardiography and biomarker measurements were performed. Participants were monitored every 6th month throughout the intervention. The cardiac biomarker N-terminal proBNP (NT-proBNP) and echocardiographic changes were monitored and mortalities were registered. End-points of mortality were evaluated by Kaplan-Meier plots and Cox proportional hazard ratios were adjusted for potential confounding factors. Intention-to-treat and per-protocol analyses were applied. During a follow up time of 5.2 years a significant reduction of cardiovascular mortality was found in the active treatment group vs. the placebo group (5.9% vs. 12.6%; P=0.015). NT-proBNP levels were significantly lower in the active group compared with the placebo group (mean values: 214 ng/L vs. 302 ng/L at 48 months; P=0.014). In echocardiography a significant better cardiac function score was found in the active supplementation compared to the placebo group (P=0.03). Long-term supplementation of selenium/coenzyme Q10 reduces cardiovascular mortality. The positive effects could also be seen in NT-proBNP levels and on echocardiography.

    Malaria control intervention coverage increased nationwide in Malawi during 2000-2010. Trends in intervention coverage were assessed against trends in malaria parasite prevalence, severe anemia (hemoglobin cause mortality in children under 5 years of age (ACCM) using nationally representative household surveys. Associations between insecticide-treated net (ITN) ownership, malaria morbidity, and ACCM were also assessed. Household ITN ownership increased from 27.4% (95% confidence interval [CI] = 25.9-29.0) in 2004 to 56.8% (95% CI = 55.6-58.1) in 2010. Similarly intermittent preventive treatment during pregnancy coverage increased from 28.2% (95% CI = 26.7-29.8) in 2000 to 55.0% (95% CI = 53.4-56.6) in 2010. Malaria parasite prevalence decreased significantly from 60.5% (95% CI = 53.0-68.0) in 2001 to 20.4% (95% CI = 15.7-25.1) in 2009 in children aged 6-35 months. Severe anemia prevalence decreased from 20.4% (95% CI: 17.3-24.0) in 2004 to 13.1% (95% CI = 11.0-15.4) in 2010 in children aged 6-23 months. ACCM decreased 41%, from 188.6 deaths per 1,000 live births (95% CI = 179.1-198.0) during 1996-2000, to 112.1 deaths per 1,000 live births (95% CI = 105.8-118.5) during 2006-2010. When controlling for other covariates in random effects logistic regression models, household ITN ownership was protective against malaria parasitemia in children (odds ratio [OR] = 0.81, 95% CI = 0.72-0.92) and severe anemia (OR = 0.82, 95% CI = 0.72-0.94). After considering the magnitude of changes in malaria intervention coverage and nonmalaria factors, and given the contribution of malaria to all-cause mortality in malaria-endemic countries, the substantial increase in malaria control interventions likely improved child survival in Malawi during 2000-2010.

  16. Robust Control for Lateral and Longitudinal Channels of Small-Scale Unmanned Helicopters

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Lateral and longitudinal channels are two closely related channels whose control stability influences flight performance of small-scale unmanned helicopters directly. This paper presents a robust control approach for lateral and longitudinal channels in the presence of parameter uncertainties and exogenous disturbances. The proposed control approach is performed by two steps. First, by performing system identification in frequency domain, system model of lateral and longitudinal channels can be accurately identified. Then, a robust H∞ state feedback controller is designed to stabilize the helicopter in lateral and longitudinal channels simultaneously under extraneous disturbances situation. The proposed approach takes advantages that it reduces order of the controller by preestimating some parameters (like flapping angles without sacrificing control accuracy. Numerical results show the reliability and effectiveness of the proposed method.

    Purpose: To fit the individual biochemical recurrence-free survival (bRFS) data from patients treated with postprostatectomy radiation therapy (RT) with a comprehensive tumor control probability (TCP) model. Methods and Materials: Considering pre-RT prostate-specific antigen (PSA) as a surrogate of the number of clonogens, bRFS may be expressed as a function of dose-per-fraction–dependent radiosensitivity (α{sub eff}), the number of clonogens for pre-RT PSA = 1 ng/mL (C), and the fraction of patients who relapse because of clonogens outside the treated volume (K), assumed to depend (linearly or exponentially) on pre-RT PSA and Gleason score (GS). Data from 894 node-negative, ≥pT2, pN0 hormone-naive patients treated with adjuvant (n=331) or salvage (n=563) intent were available: 5-year bRFS data were fitted grouping patients according to GS (<7:392, =7:383, >7:119). Results: The median follow-up time, pre-RT PSA, and dose were 72 months, 0.25 ng/mL, and 66.6 Gy (range 59.4-77.4 Gy), respectively. The best-fit values were 0.23 to 0.26 Gy{sup −1} and 10{sup 7} for α{sub eff} and C for the model considering a linear dependence between K and PSA. Calibration plots showed good agreement between expected and observed incidences (slope: 0.90-0.93) and moderately high discriminative power (area under the curve [AUC]: 0.68-0.69). Cross-validation showed satisfactory results (average AUCs in the training/validation groups: 0.66-0.70). The resulting dose-effect curves strongly depend on pre-RT PSA and GS. bRFS rapidly decreases with PSA: the maximum obtainable bRFS (defined as 95% of the maximum) declined by about 2.7% and 4.5% for each increment of 0.1 ng/mL for GS <7 and ≥7, respectively. Conclusions: Individual data were fitted by a TCP model, and the resulting best-fit parameters were radiobiologically consistent. The model suggests that relapses frequently result from clonogens outside the irradiated volume, supporting the choice of lymph

    Full Text Available Automotive vehicle following systems are essential for the design of automated highway system. The problem associated with the automatic vehicle following system is the string stability of the platoon of vehicles, i.e. the problem of uniform velocity and spacing errors propagation. Different control algorithm for the longitudinal control of a platoon are discussed based on different spacing policies, communication link among the vehicles of a platoon, and the performance of a platoon have been analysed in the presence of disturbance (noise and parametric uncertainties. This paper presented the PID (Proportional Integral Derivative feedback control algorithm for the longitudinal control of a platoon in the presence of noise signal and investigates the performance of platoon under the influence of sudden acceleration and braking in severe conditions. This model has been applied on 6 vehicles moving in a platoon. The platoon has been analysed to retain the uniform velocity and safe spacing among the vehicles. The limitations of PID control algorithm have been discussed and the alternate methods have been suggested. Model simulations, in comparison with the literature, are also presented.

    Although effective in superficial basal cell carcinoma (BCC), the treatment effect of photodynamic therapy (PDT) in nodular BCC (nBCC) is still questionable. The relation between tumor thickness and PDT failure is unclear. We sought to compare long-term effectiveness of fractionated 20% 5-aminolevulinic acid (ALA)-PDT with prior partial debulking versus surgical excision in nBCC. The effect of tumor thickness on ALA-PDT failure was analyzed. 173 primary, histologically proven nBCCs in 151 patients were randomized to fractionated ALA-PDT (n = 85) or surgical excision (n = 88). Two PDT illuminations were performed with a 1-hour interval. Follow-up was at least 5 years posttreatment. Clinical recurrences were confirmed histologically. A total of 171 nBCCs were treated and had a median follow-up of 67 months (range 0-106). At 60 months, 23 tumors had recurred in the ALA-PDT group and 2 tumors in the surgical excision group. Cumulative recurrence probabilities 5 years posttreatment were 30.7% (95% confidence interval [CI] 21.5%-42.6%) for ALA-PDT and 2.3% (95% CI 0.6%-8.8%) for surgical excision (P treatment, PDT might be an alternative for inoperable patients with thin (≤0.7 mm) nBCC.

    This 5-year prospective follow-up of women randomized to general anesthesia (GA) with or without a thoracic paravertebral block (TPVB) examined the risk of local recurrence, metastasis and mortality after breast cancer surgery. A total of 180 patients undergoing modified radical mastectomy were randomized to one of three study groups: standardized GA only; GA with a single-injection TPVB (s-TPVB) and placebo paravertebral infusion after surgery for 72-h; and GA plus with continuous TPVB (c-TPVB) for 72-h postoperatively. Cox proportional models were used to assess the effect of TPVB on long-term outcomes. Equivalence testing was used to help interpret the results. The incidence [95% confidence interval (CI)] of cancer recurrence, metastatic spread and all-cause mortality was 2.3% (0.7-5.4%), 7.9% (4.6-12.6%) and 6.8% (3.6-11.2%), respectively. Four women had cancer recurrence and had metastatic spread. Compared to the GA-only group, the risk of metastatic spread was not different from that of GA with s-TPVB [hazard ratio (HR)=1.11, 95% CI=0.32-3.83) nor from that with GA plus c-TPVB (HR=0.79, 95% CI=0.21-2.96) (p=0.88). Compared to the GA-only group, the risk of mortality was similarly not different from that of the two other groups (HR=2.57, 95% CI=0.66-9.92; and HR=0.66, 95% CI=0.11-3.97, respectively, p=0.15). Although the original study was underpowered to properly address long-term outcomes, the results of this analysis suggest that TPVB, administered whether as a single-injection or continuous infusion during the perioperative period, had little to no appreciable effect on local recurrence, metastasis or mortality after breast cancer surgery.

    The aim of this study was to establish the longitudinal relationship between hearing ability in noise and psychosocial health outcomes (i.e., loneliness, anxiety, depression, distress, and somatization) in adults aged 18 to 70 years. An additional objective was to determine whether a change in hearing ability in noise over a period of 5 years was associated with a change in psychosocial functioning. Subgroup effects for a range of factors were investigated. Longitudinal data of the web-based Netherlands Longitudinal Study on Hearing (NL-SH) (N = 508) were analyzed. The ability to recognize speech in noise (i.e., the speech-reception-threshold [SRTn]) was measured with an online digit triplet test at baseline and at 5-year follow-up. Psychosocial health status was assessed by online questionnaires. Multiple linear regression analyses and longitudinal statistical analyses (i.e., generalized estimating equations) were performed. Poorer SRTn was associated longitudinally with more feelings of emotional and social loneliness. For participants with a high educational level, the longitudinal association between SRTn and social loneliness was significant. Changes in hearing ability and loneliness appeared significantly associated only for specific subgroups: those with stable pattern of hearing aid nonuse (increased emotional and social loneliness), who entered matrimony (increased social loneliness), and low educational level (less emotional loneliness). No significant longitudinal associations were found between hearing ability and anxiety, depression, distress, or somatization. Hearing ability in noise was longitudinally associated with loneliness. Decline in hearing ability in noise was related to increase in loneliness for specific subgroups of participants. One of these subgroups included participants whose hearing deteriorated over 5 years, but who continued to report nonuse of hearing aids. This is an important and alarming finding that needs further investigation.

    Full Text Available The dynamic behavior of a multitower cable-stayed bridge with the application of partially longitudinal constraint system using viscous fluid dampers under real earthquake ground motions is presented. The study is based on the dynamic finite element model of the Jiashao Bridge, a six-tower cable-stayed bridge in China. The prime aim of the study is to investigate the effectiveness of viscous fluid dampers on the longitudinal seismic responses of the bridge and put forth a multiobjective optimization design method to determine the optimized parameters of the viscous fluid dampers. The results of the investigations show that the control objective of the multitower cable-stayed bridge with the partially longitudinal constraint system is to yield maximum reductions in the base forces of bridge towers longitudinally restricted with the bridge deck, with slight increases in the base forces of bridge towers longitudinally unrestricted with the bridge deck. To this end, a multiobjective optimization design method that uses a nondominating sort genetic algorithm II (NSGA-II is used to optimize parameters of the viscous fluid dampers. The effectiveness of the proposed optimization design method is demonstrated for the multitower cable-stayed bridge with the partially longitudinal constraint system, which reveals that a design engineer can choose a set of proper parameters of the viscous fluid dampers from Pareto optimal fronts that can satisfy the desired performance requirements.

    Wheeled mobile robots (WMRs) often suffer from the longitudinal slipping when moving on the loose soil of the surface of the moon during exploration. Longitudinal slip is the main cause of WMRs' delay in trajectory tracking. In this paper, a nonlinear extended state observer (NESO) is introduced to estimate the longitudinal velocity in order to estimate the slip ratio and the derivative of the loss of velocity which are used in modelled disturbance compensation. Owing to the uncertainty and disturbance caused by estimation errors, a multi-objective controller using the mixed H2/H∞ method is employed to ensure the robust stability and performance of the WMR system. The final inputs of the trajectory tracking consist of the feedforward compensation, compensation for the modelled disturbances and designed multi-objective control inputs. Finally, the simulation results demonstrate the effectiveness of the controller, which exhibits a satisfactory tracking performance.

    Purpose: To report the 5-year results of a technique of prone breast radiation therapy delivered by a regimen of accelerated intensity modulated radiation therapy with a concurrent boost to the tumor bed. Methods and Materials: Between 2003 and 2006, 404 patients with stage I-II breast cancer were prospectively enrolled into 2 consecutive protocols, institutional trials 03-30 and 05-181, that used the same regimen of 40.5 Gy/15 fractions delivered to the index breast over 3 weeks, with a concomitant daily boost to the tumor bed of 0.5 Gy (total dose 48 Gy). All patients were treated after segmental mastectomy and had negative margins and nodal assessment. Patients were set up prone: only if lung or heart volumes were in the field was a supine setup attempted and chosen if found to better spare these organs. Results: Ninety-two percent of patients were treated prone, 8% supine. Seventy-two percent had stage I, 28% stage II invasive breast cancer. In-field lung volume ranged from 0 to 228.27 cm{sup 3}, mean 19.65 cm{sup 3}. In-field heart volume for left breast cancer patients ranged from 0 to 21.24 cm{sup 3}, mean 1.59 cm{sup 3}. There was no heart in the field for right breast cancer patients. At a median follow-up of 5 years, the 5-year cumulative incidence of isolated ipsilateral breast tumor recurrence was 0.82% (95% confidence interval [CI] 0.65%-1.04%). The 5-year cumulative incidence of regional recurrence was 0.53% (95% CI 0.41%-0.69%), and the 5-year overall cumulative death rate was 1.28% (95% CI 0.48%-3.38%). Eighty-two percent (95% CI 77%-85%) of patients judged their final cosmetic result as excellent/good. Conclusions: Prone accelerated intensity modulated radiation therapy with a concomitant boost results in excellent local control and optimal sparing of heart and lung, with good cosmesis. Radiation Therapy Oncology Group protocol 1005, a phase 3, multi-institutional, randomized trial is ongoing and is evaluating the equivalence of a similar dose and

    Severe obesity in adolescence is associated with reduced life expectancy and impaired quality of life. Long-term benefits of conservative treatments in adolescents are known to be modest, whereas short-term outcomes of adolescent bariatric surgery are promising. We aimed to compare 5-year outcomes of adolescent surgical patients after Roux-en-Y gastric bypass with those of conservatively treated adolescents and of adults undergoing Roux-en-Y gastric bypass, in the Adolescent Morbid Obesity Surgery (AMOS) study. We did a nationwide, prospective, non-randomised controlled study of adolescents (aged 13-18 years) with severe obesity undergoing Roux-en-Y gastric bypass at three specialised paediatric obesity treatment centres in Sweden. We compared clinical outcomes in adolescent surgical patients with those of matched adolescent controls undergoing conservative treatment and of adult controls undergoing Roux-en-Y gastric bypass. The primary outcome measure was change in BMI over 5 years. We used multilevel mixed-effect regression models to assess longitudinal changes. This trial is registered with ClinicalTrials.gov, number NCT00289705. Between April, 2006, and May, 2009, 100 adolescents were recruited to the study, of whom 81 underwent Roux-en-Y gastric bypass (mean age 16·5 years [SD 1·2], bodyweight 132·8 kg [22·1], and BMI 45·5 kg/m(2) [SD 6·1]). 80 matched adolescent controls and 81 matched adult controls were enrolled for comparison of outcomes. The change in bodyweight in adolescent surgical patients over 5 years was -36·8 kg (95% CI -40·9 to -32·8), resulting in a reduction in BMI of -13·1 kg/m(2) (95% CI -14·5 to -11·8), although weight loss less than 10% occurred in nine (11%). Mean BMI rose in adolescent controls (3·3 kg/m(2), 95% CI 1·1-4·8) over the 5-year study period, whereas the BMI change in adult controls was similar to that in adolescent surgical patients (mean change -12·3 kg/m(2), 95% CI -13·7 to -10·9).

    The present paper addresses an experimental investigation of the dynamic and the control of a longitudinal vortex emanating from the front pillar of a dihedral bluff body corresponding to a simplified geometry of an automotive vehicle. The control system is based on a thin rectangular slot located along the lateral edge of the windscreen and provides steady suction or blowing normal to the lateral face of the geometry. Qualitative results obtained with dye visualizations and Schlieren photos provide an overview of the impact of the control on the topology of the vortex flow. Quantitative Stereo-PIV measurements and unsteady forces measurements are used to characterize the interaction between the control and the longitudinal vortex. Controls that change significantly the topology of the vortex core and reduce aerodynamic drag are identified. (orig.)

    Followup results from the Drug Abuse Treatment Outcome Studies (DATOS) 1-year and 5-year followups were used to describe the long-term outcomes of drug treatment and to further clarify the relationship between treatment duration and post-treatment outcomes in four treatment modalities: outpatient methadone, long-term residential (LTR), outpatient drug free (ODF), and short-term inpatient. Methods replicating those used in earlier analyses of the DATOS 1-year followup of 2,966 patients admitted to treatment in 1991-1993 and those of the Treatment Outcome Prospective Study patients admitted in 1979-1981 were employed. DATOS is a non-experimental longitudinal study conducted within the natural settings of 96 treatment programs in the U.S.A. The study followed patients during and after treatment at specified periods of time. Prevalence of drug use and behaviors were evaluated for the year prior to treatment; and the post-treatment time frames defined by the 1- and 5-year followups. In addition, the multivariate analytic technique of generalized estimating equations was used to examine the relationship of treatment duration and outcomes across both followups while also controlling for patient characteristics and pretreatment levels of behaviors. The 5-year stratified followup sample included 1,393 of the same individuals in the 1-year followup sample. Analyses were restricted to patients participating in both followups. Reductions in prevalence of cocaine use in the year after treatment (compared to the preadmission year) by patients were associated with longer treatment durations (particularly 6 months or more in LTR and ODF). In addition, reductions in illegal activity and increases in full-time employment were related to treatment stays of 6 months or longer for patients in LTR. The DATOS results from the 1-year and 5-year post-treatment followup combined suggest the stability of outcomes of substance abuse treatment. While results are generally consistent with the

    To quantify retinal nerve fiber layer (RNFL) changes in patients with multiple sclerosis (MS) and healthy controls with a 5-year follow-up and to analyze correlations between disability progression and RNFL degeneration. Observational and longitudinal study. One hundred patients with relapsing-remitting MS and 50 healthy controls. All participants underwent a complete ophthalmic and electrophysiologic exploration and were re-evaluated annually for 5 years. Visual acuity (Snellen chart), color vision (Ishihara pseudoisochromatic plates), visual field examination, optical coherence tomography (OCT), scanning laser polarimetry (SLP), and visual evoked potentials. Expanded Disability Status Scale (EDSS) scores, disease duration, treatments, prior optic neuritis episodes, and quality of life (QOL; based on the 54-item Multiple Sclerosis Quality of Life Scale score). Optical coherence tomography (OCT) revealed changes in all RNFL thicknesses in both groups. In the MS group, changes were detected in average thickness and in the mean deviation using the GDx-VCC nerve fiber analyzer (Laser Diagnostic Technologies, San Diego, CA) and in the P100 latency of visual evoked potentials; no changes were detected in visual acuity, color vision, or visual fields. Optical coherence tomography showed greater differences in the inferior and temporal RNFL thicknesses in both groups. In MS patients only, OCT revealed a moderate correlation between the increase in EDSS and temporal and superior RNFL thinning. Temporal RNFL thinning based on OCT results was correlated moderately with decreased QOL. Multiple sclerosis patients exhibit a progressive axonal loss in the optic nerve fiber layer. Retinal nerve fiber layer thinning based on OCT results is a useful marker for assessing MS progression and correlates with increased disability and reduced QOL.

  19. Olfactory dysfunction predicts 5-year mortality in older adults.

    Directory of Open Access Journals (Sweden)

    Jayant M Pinto

    Full Text Available Prediction of mortality has focused on disease and frailty, although antecedent biomarkers may herald broad physiological decline. Olfaction, an ancestral chemical system, is a strong candidate biomarker because it is linked to diverse physiological processes. We sought to determine if olfactory dysfunction is a harbinger of 5-year mortality in the National Social Life, Health and Aging Project [NSHAP], a nationally representative sample of older U.S. adults. 3,005 community-dwelling adults aged 57-85 were studied in 2005-6 (Wave 1 and their mortality determined in 2010-11 (Wave 2. Olfactory dysfunction, determined objectively at Wave 1, was used to estimate the odds of 5-year, all cause mortality via logistic regression, controlling for demographics and health factors. Mortality for anosmic older adults was four times that of normosmic individuals while hyposmic individuals had intermediate mortality (p<0.001, a "dose-dependent" effect present across the age range. In a comprehensive model that included potential confounding factors, anosmic older adults had over three times the odds of death compared to normosmic individuals (OR, 3.37 [95%CI 2.04, 5.57], higher than and independent of known leading causes of death, and did not result from the following mechanisms: nutrition, cognitive function, mental health, smoking and alcohol abuse or frailty. Olfactory function is thus one of the strongest predictors of 5-year mortality and may serve as a bellwether for slowed cellular regeneration or as a marker of cumulative toxic environmental exposures. This finding provides clues for pinpointing an underlying mechanism related to a fundamental component of the aging process.

  20. Multiple-Vehicle Longitudinal Collision Mitigation by Coordinated Brake Control

    2014-01-01

    Full Text Available Rear-end collision often leads to serious casualties and traffic congestion. The consequences are even worse for multiple-vehicle collision. Many previous works focused on collision warning and avoidance strategies of two consecutive vehicles based on onboard sensor detection only. This paper proposes a centralized control strategy for multiple vehicles to minimize the impact of multiple-vehicle collision based on vehicle-to-vehicle communication technique. The system is defined as a coupled group of vehicles with wireless communication capability and short following distances. The safety relationship can be represented as lower bound limit on deceleration of the first vehicle and upper bound on maximum deceleration of the last vehicle. The objective is to determine the desired deceleration for each vehicle such that the total impact energy is minimized at each time step. The impact energy is defined as the relative kinetic energy between a consecutive pair of vehicles (approaching only. Model predictive control (MPC framework is used to formulate the problem to be constrained quadratic programming. Simulations show its effectiveness on collision mitigation. The developed algorithm has the potential to be used for progressive market penetration of connected vehicles in practice.

  1. Longitudinal elastic wave control by pre-deforming semi-linear materials.

    2017-09-01

    An incremental wave superimposed on a pre-deformed hyper-elastic material perceives an elastic media with the instantaneous modulus of the current material. This offers a new route with a broadband feature to control elastic waves by purposely creating finite deformation field. This study proves that the governing equation of a semi-linear material under a symmetric pre-deformation condition maintains the form invariance for longitudinal wave, so the longitudinal wave control can be made by transformation method without the constraint condition on principle stretches; however, this is not the case for shear waves. Therefore, pre-deforming a semi-linear material provides a potential method for treating longitudinal and shear waves differently. Examples with elastic wave control and band structure shift through pre-deforming a semi-linear material are provided to illustrate this finding. Finally, a one-dimensional spring lattice is proposed to mimic a semi-linear material, and the dispersion relation for longitudinal waves in a sandwich structure with such spring lattice is shown to be invariant during elongation, confirming the result found based on a homogeneous semi-linear material. These results may stimulate researches on designing new hyper-elastic microstructures as well as designing new devices based on pre-deformed hyper-elastic materials.

    1995-01-01

    This report discusses different approaches to stable H infinity controller design applied to the problem of augmenting the longitudinal dynamics of an aircraft. Stability of the H infinity controller is investigated by analyzing the effects of changes in the performance index weights, and modifications in the measured outputs. The existence of a stable suboptimal controller is also investigated. It is shown that this is equivalent to finding a stable controller, whose infinity norm is less than a specified bound, for an unstable plant which is determined from parametrization of all H infinity controllers. Examples are given for a gust alleviation and a command tracking problem.

    Autonomic dysfunction after spinal cord injury (SCI) is an under-researched area when compared with motor and sensory dysfunction. Cardiovascular autonomic dysfunction is a particular concern, leading to impaired control of blood pressure and heart rate. (1) To determine the prevalence of hypotension in individuals with SCI during and after rehabilitation; (2) To investigate changes in cardiovascular variables during and after rehabilitation; (3) To evaluate the influence of personal and lesion characteristics on cardiovascular variables. Cardiovascular variables (resting systolic [SAP] and diastolic [DAP] arterial pressures and resting [HRrest] and peak heart rates [HRpeak]) were measured on 5 test occasions: start of inpatient rehabilitation, 3 months later, at discharge, and at 1 and 5 years after discharge. The time course and effects of personal and lesion characteristics on cardiovascular variables were studied using multilevel regression analyses. The prevalence of hypotension was unchanged during rehabilitation and for 5 years after discharge. Odds for hypotension were highest in those with cervical and high thoracic lesions, younger individuals, and men. DAP increased during the 5 years after discharge. HRrest decreased during and after rehabilitation. SAP, DAP, HRrest, and HRpeak were lowest in those with cervical and high thoracic lesions. SAP and DAP increased with age; HRpeak decreased with age. These longitudinal data provide normative values for blood pressure and heart rate changes with time after injury according to lesion and personal characteristics. These results can be used to guide clinical practice and place changes in cardiovascular function caused by interventions in perspective.

    Findings on the relation of maternal verbal teaching strategies to children's effortful control (EC; i.e., self-regulation) are limited in quantity and somewhat inconsistent. In this study, children's EC was assessed at 18, 30, and 42 months (ns = 255, 229, and 209, respectively) with adults' reports and a behavioral measure. Mothers' verbal teaching strategies were assessed while the mother and child worked on a task together. Children's general vocabulary also was measured. In a structural panel model taking into account prior levels of constructs and correlations within time, as well as the relations of EC and teaching strategies to children's vocabulary, socioeconomic status, age, and sex of the child, 18-month EC positively predicted mothers' 30-month cognitive assistance and questioning strategies and negatively predicted 30-month maternal directive strategies. In addition, high 30-month EC predicted greater 42-month maternal cognitive assistance and fewer directive strategies. Thus, mothers' teaching strategies were predicted by individual differences in self-regulatory skills, supporting potential evocative child effects on mothers' teaching strategies.

  8. Longitudinal Motion Control of AUV Based on Fuzzy Sliding Mode Method

    Directory of Open Access Journals (Sweden)

    Duo Qi

    2016-01-01

    Full Text Available According to the characteristics of AUV movement, a fuzzy sliding mode controller was designed, in which fuzzy rules were adopted to estimate the switching gain to eliminate disturbance terms and reduce chattering. The six-degree-of-freedom model of AUV was simplified and longitudinal motion equations were established on the basis of previous research. The influences of first-order wave force and torque were taken into consideration. The REMUS was selected to simulate the control effects of conventional sliding mode controller and fuzzy sliding mode controller. Simulation results show that the fuzzy sliding mode controller can meet the requirements and has higher precision and stronger antijamming performances compared with conventional sliding mode controller.

  9. Longitudinal Beam Dynamics Studies at CTF3 And Pulse Compressor Controlling

    CERN Document Server

    Shaker, S H

    2009-01-01

    The aim of the CLIC Test Facility CTF3, built at CERN by an international collaboration, is to address the main feasibility issues of the CLIC electron-positron linear collider technology by 2010. One key-issue studied at CTF3 is the generation of the very high current drive beam, used in CLIC as the RF power source. It is particularly important to simulate and control the drive beam longitudinal dynamics in the drive beam generation complex, since it directly affects the efficiency and stability of the RF power production process. In this thesis how to use pulse compressors to achieve a high RF power in the drive beam accelerator is discussed. We also describe the ongoing effort in modelling the longitudinal evolution of the CTF3 drive beam and compare the simulations with experimental results. Our study is based on the single bunch simulation.

    2016-10-01

    There are contradictions among speediness, anti-disturbance performance, and steady-state accuracy caused by traditional PID controller in the existing light source systems of thermal frequency stabilizing laser with double longitudinal modes. In this paper, a new kind of fuzzy adaptive PID controller was designed by combining fuzzy PID control technology and expert system to make frequency stabilizing system obtain the optimal performance. The experiments show that the frequency stability of the designed PID controller is similar to the existing PID controller (the magnitude of frequency stability is less than 10-9 in constant temperature and 10-7 in open air). But the preheating time is shortened obviously (from 10 minutes to 5 minutes) and the anti-disturbance capability is improved significantly (the recovery time needed after strong interference is reduced from 1 minute to 10 seconds).

    Abstract Background: To understand whether the relationship between young children's autonomic nervous system (ANS) responses predicted their BMI, or vice versa, the association between standardized BMI (zBMI) at 2, 3.5, and 5 years of age and ANS reactivity at 3.5–5 years of age, and whether zBMI predicts later ANS reactivity or whether early ANS reactivity predicts later zBMI, was studied. Methods: Low-income, primarily Latino children (n=112) were part of a larger cohort study of mothers recruited during early pregnancy. Study measures included maternal prenatal weight, children's health behaviors (i.e., time watching television, fast food consumption, and time playing outdoors), children's height and weight at 2, 3.5, and 5 years, and children's ANS reactivity at 3.5 and 5 years. ANS measures of sympathetic nervous system (i.e., pre-ejection period) and parasympathetic nervous system (i.e., respiratory sinus arrhythmia) activity were monitored during rest and four challenges. Reactivity was calculated as the difference between mean challenge response and rest. Structural equation models analyzed the relationship between children's zBMI at 2, 3.5, and 5 years and ANS reactivity at 3.5 and 5 years, adjusting for mother's BMI, children's behaviors, and changes in height. Results: There was no association between zBMI and ANS cross-sectionally. Children with high zBMI at 2 or 3.5 years or large zBMI increases from 2 to 3.5 years of age had decreased sympathetic activity at 5 years. Neither sympathetic nor parasympathetic reactivity at 3.5 years predicted later zBMI. Conclusions: Increased zBMI early in childhood may dampen young children's SNS responses later in life.

    Control-theoretic modeling of the human operator dynamic behavior in manual control tasks has a long and rich history. In the last two decades, there has been a renewed interest in modeling the human operator. There has also been significant work on techniques used to identify the pilot model of a given structure. The purpose of this research is to attempt to go beyond pilot identification based on collected experimental data and to develop a predictor of pilot behavior. An experiment was conducted to categorize these interactions of the pilot with an adaptive controller compensating during control surface failures. A general linear in-parameter model structure is used to represent a pilot. Three different estimation methods are explored. A gradient descent estimator (GDE), a least squares estimator with exponential forgetting (LSEEF), and a least squares estimator with bounded gain forgetting (LSEBGF) used the experiment data to predict pilot stick input. Previous results have found that the GDE and LSEEF methods are fairly accurate in predicting longitudinal stick input from commanded pitch. This paper discusses the accuracy of each of the three methods - GDE, LSEEF, and LSEBGF - to predict both pilot longitudinal and lateral stick input from the flight director's commanded pitch and bank attitudes.

  15. Model predictive controller-based multi-model control system for longitudinal stability of distributed drive electric vehicle.

    Shi, Ke; Yuan, Xiaofang; Liu, Liang

    2018-01-01

    Distributed drive electric vehicle(DDEV) has been widely researched recently, its longitudinal stability is a very important research topic. Conventional wheel slip ratio control strategies are usually designed for one special operating mode and the optimal performance cannot be obtained as DDEV works under various operating modes. In this paper, a novel model predictive controller-based multi-model control system (MPC-MMCS) is proposed to solve the longitudinal stability problem of DDEV. Firstly, the operation state of DDEV is summarized as three kinds of typical operating modes. A submodel set is established to accurately represent the state value of the corresponding operating mode. Secondly, the matching degree between the state of actual DDEV and each submodel is analyzed. The matching degree is expressed as the weight coefficient and calculated by a modified recursive Bayes theorem. Thirdly, a nonlinear MPC is designed to achieve the optimal wheel slip ratio for each submodel. The optimal design of MPC is realized by parallel chaos optimization algorithm(PCOA)with computational accuracy and efficiency. Finally, the control output of MPC-MMCS is computed by the weighted output of each MPC to achieve smooth switching between operating modes. The proposed MPC-MMCS is evaluated on eight degrees of freedom(8DOF)DDEV model simulation platform and simulation results of different condition show the benefits of the proposed control system.

    Limited human data are available to assess the association between prenatal mercury vapor (Hg⁰)) exposure from maternal dental amalgam restorations and neurodevelopment of children. We evaluated the association between maternal dental amalgam status during gestation and children's neurodevelopmental outcomes at 5 years in the Seychelles Child Development Nutrition Study (SCDNS). Maternal amalgam status was determined prospectively in a longitudinal cohort study examining the associations of prenatal exposure to nutrients and methylmercury (MeHg) with neurodevelopment. A total of 236 mother-child pairs initially enrolled in the SCDNS in 2001 were eligible to participate. Maternal amalgam status was measured as number of amalgam surfaces (the primary metric) and number of occlusal points. The neurodevelopmental assessment battery was comprised of age-appropriate tests of cognitive, language, and perceptual functions, and scholastic achievement. Linear regression analysis controlled for MeHg exposure, maternal fatty acid status, and other covariates relevant to child development. Maternal amalgam status evaluation yielded an average of 7.0 surfaces (range 0-28) and 11.0 occlusal points (range 0-40) during pregnancy. Neither the number of maternal amalgam surfaces nor occlusal points were associated with any outcome. Our findings do not provide evidence to support a relationship between prenatal exposure to Hg⁰ from maternal dental amalgam and neurodevelopmental outcomes in children at 5 years of age. © 2013.

    Recent years many flight control systems and industries are employing PID controllers to improve the dynamic behavior of the characteristics. In this paper, PID controller is developed to improve the stability and performance of general aviation aircraft system. Designing the optimum PID controller parameters for a pitch control aircraft is important in expanding the flight safety envelope. Mathematical model is developed to describe the longitudinal pitch control of an aircraft. The PID controller is designed based on the dynamic modeling of an aircraft system. Different tuning methods namely Zeigler-Nichols method (ZN), Modified Zeigler-Nichols method, Tyreus-Luyben tuning, Astrom-Hagglund tuning methods are employed. The time domain specifications of different tuning methods are compared to obtain the optimum parameters value. The results prove that PID controller tuned by Zeigler-Nichols for aircraft pitch control dynamics is better in stability and performance in all conditions. Future research work of obtaining optimum PID controller parameters using artificial intelligence techniques should be carried out.

    Controlling single-particle wave functions in single semiconductor quantum dots is in demand to implement solid-state quantum information processing and spintronics. Normally, particle wave functions can be tuned transversely by an perpendicular magnetic field. We report a longitudinal wave function control in single quantum dots with a magnetic field. For a pure InAs quantum dot with a shape of pyramid or truncated pyramid, the hole wave function always occupies the base because of the less confinement at base, which induces a permanent dipole oriented from base to apex. With applying magnetic field along the base-apex direction, the hole wave function shrinks in the base plane. Because of the linear changing of the confinement for hole wave function from base to apex, the center of effective mass moves up during shrinking process. Due to the uniform confine potential for electrons, the center of effective mass of electrons does not move much, which results in a permanent dipole moment change and an inverted electron-hole alignment along the magnetic field direction. Manipulating the wave function longitudinally not only provides an alternative way to control the charge distribution with magnetic field but also a new method to tune electron-hole interaction in single quantum dots.

    OBJECTIVE To compare whether depressive symptoms are more strongly related to subsequent or prior glycemic control in type 2 diabetes and to test whether patient characteristics modify these longitudinal associations. RESEARCH DESIGN AND METHODS On two occasions separated by 6 months, depressive symptoms and glycemic control were assessed in 253 adults with type 2 diabetes. Regression analyses examined depressive symptoms as both a predictor and outcome of glycemic control and tested whether medication regimen (e.g., insulin versus oral drugs) was an effect modifier before and after adjusting for baseline levels of the outcome being predicted. RESULTS Depressive symptom severity predicted poor glycemic control 6 months later (P = 0.018) but not after baseline glycemic control was taken into account (P = 0.361). Although baseline glycemic control did not generally predict depressive symptoms 6 months later (P = 0.558), it significantly interacted with regimen (P = 0.008). Specifically, glycemic control predicted depressive symptoms among patients prescribed insulin (β = 0.31, P = 0.002) but not among those prescribed oral medication alone (β = −0.10, P = 0.210). Classifying depression dichotomously produced similar but weaker findings. CONCLUSIONS Depressive symptoms do not necessarily lead to worsened glycemic control. In contrast, insulin-treated patients in poor glycemic control are at moderate risk for worsening of depressive symptoms. These patients should be carefully monitored to determine whether depression treatment should be initiated or intensified. PMID:19389814

    Grant, Angela M; Fang, Shin-Yi; Li, Ping

    2015-05-01

    In this paper we report a longitudinal functional magnetic resonance imaging (fMRI) study that tested contrasting predictions about the time course of cognitive control in second language (L2) acquisition. We examined the neural correlates of lexical processing in L2 learners twice over the course of one academic year. Specifically, while in the scanner, participants were asked to judge the language membership of unambiguous first and second language words, as well as interlingual homographs. Our ROI and connectivity analyses reveal that with increased exposure to the L2, overall activation in control areas such as the anterior cingulate cortex decrease while connectivity with semantic processing regions such as the middle temporal gyrus increase. These results suggest that cognitive control is more important initially in L2 acquisition, and have significant implications for understanding developmental and neurocognitive models of second language lexical processing.

    Deteriorating job control has been previously shown to predict poor mental health. The impact of improvement in job control on mental health is less well understood, yet it is of policy significance. We used fixed-effects longitudinal regression models to analyze 10 annual waves of data from a large Australian panel survey (2001-2010) to test within-person associations between change in self-reported job control and corresponding change in mental health as measured by the Mental Component Summary score of Short Form 36. We found evidence of a graded relationship; with each quintile increase in job control experienced by an individual, the person's mental health increased. The biggest improvement was a 1.55-point increase in mental health (95% confidence interval: 1.25, 1.84) for people moving from the lowest (worst) quintile of job control to the highest. Separate analyses of each of the component subscales of job control-decision authority and skill discretion-showed results consistent with those of the main analysis; both were significantly associated with mental health in the same direction, with a stronger association for decision authority. We conclude that as people's level of job control increased, so did their mental health, supporting the value of targeting improvements in job control through policy and practice interventions. © The Author 2015.

    The purpose was to study associations between tooth brushing frequency, use of fluoride lozenges and consumption of sugary drinks at 1.5 years of age and having caries experience at 5 years of age. This study was based on data from the Norwegian Mother and Child Cohort Study conducted by the Norwegian Institute of Public Health and by the Public Dental Services. A total of 1095 children were followed from pregnancy to the age of 5 years. Questionnaires regarding oral health behavior were completed by the parents at 1.5 and 5 years of age. Clinical and radiographic examination of the children was performed at the age of 5 years. In multiple logistic regression, having caries experience at 5 years of age was associated with; at 1.5 years of age having the teeth brushed less than twice daily (OR = 2.1, CI = 1.3-3.6) and being offered sugary drinks at least once a week (OR = 1.8, CI = 1.1-2.9) when controlled for family characteristics and oral health behavior at 5 years of age. Tooth brushing frequency and consumption of sugary drinks in early childhood were related to caries development during pre-school age, independent of family characteristics and oral health behavior at 5 years of age. The results indicate that early established habits regarding tooth brushing and consumption of sugary drinks have long-term effects on caries development. Parents encountering difficulties in establishing favorable oral health behavior in children's first years of life should receive special attention from health personnel.

  4. Behavioral Control and Reward Sensitivity in Adolescents' Risk Taking Behavior: A Longitudinal TRAILS Study.

    2017-01-01

    Neurodevelopmental theories of risk behavior hypothesize that low behavioral control in combination with high reward sensitivity explains adolescents' risk behavior. However, empirical studies examining this hypothesis while including actual risk taking behavior in adolescence are lacking. In this study we tested whether the imbalance between behavioral control and reward sensitivity underlies risk taking behavior in adolescence, using a nationally representative longitudinal sample of 715 adolescents, of which 66% revealed an increased risk for mental health problems. To assess behavioral control at age 11 we used both self-report (effortful control) as well as behavioral measures of cognitive control (i.e., working memory and response inhibition). Reward sensitivity was assessed with the Bangor Gambling Task. The main finding of this study was that effortful control at age 11 was the best predictor of risk taking behavior (alcohol and cannabis use) at age 16, particularly among adolescents who were more reward sensitive. Risk taking behavior in adolescents might be explained by relatively weak behavioral control functioning combined with high sensitivity for reward.

    Dairy farming is associated with a high prevalence of respiratory disorders but the respective influence of occupational exposures, environmental, and individual factors on lung function remain unclear. In 1994 and 1999, dairy farmers were examined in the Doubs province, France. Spirometric measures and allergological tests were performed. Medical and professional data were obtained by questionnaires. A multiple linear regression analysis was performed. An accelerated decline in lung function parameters was associated with age, male sex, traditional farm (as opposed to modern farms), and a high rate of total IgE (P < 10(-2)). Blood oxygen saturation (SpO2) was significantly positively linked with the modernization of the farm and negatively with age, smoking status, and log IgE (P < 10(-2)). Geographical factors (altitude and climatic conditions) had no significant effect. The modernization of the farm has an important and beneficial impact on lung functiony.

Uptake and dropout of specific sports varied widely. Despite high levels of migration into and out of Gaelic games, they remained popular at follow-up. Weight training was the only sport that increased in both sexes (P motivations for taking up a new sport. Other commitments, a lack of interest and time were important factors leading to sports dropout.

    This research examined the overtime reciprocal relations between maternal and paternal harsh discipline and children's externalizing behavior. Seven hundred two father-mother dyads of children (6-9 years of age at baseline) completed measures of parental harsh discipline and children's externalizing behavior at five time points, 1 year apart. Autoregressive latent trajectory models revealed that maternal and paternal corporal punishment predicted subsequent children's externalizing behavior (parent-driven effects), whereas children's externalizing behavior predicted subsequent maternal and paternal psychological aggression (child-driven effects). The parent-driven effects became stronger, whereas the child-driven effects were equally strong across time. Furthermore, the parent-driven effects for corporal punishment were found for both boys and girls, whereas the child-driven effects for psychological aggression were found only for boys. © 2017 The Authors.

  10. Design and Implementation of IIR Algorithms for Control of Longitudinal Coupled-Bunch Instabilities

    Energy Technology Data Exchange (ETDEWEB)

    Teytelman, Dmitry

    2000-05-16

    The recent installation of third-harmonic RF cavities at the Advanced Light Source has raised instability growth rates, and also caused tune shifts (coherent and incoherent) of more than an octave over the required range of beam currents and energies. The larger growth rates and tune shifts have rendered control by the original bandpass FIR feedback algorithms unreliable. In this paper the authors describe an implementation of an IIR feedback algorithm with more exible response tailoring. A cascade of up to 6 second-order IIR sections (12 poles and 12 zeros) was implemented in the DSPs of the longitudinal feedback system. Filter design has been formulated as an optimization problem and solved using constrained optimization methods. These IIR filters provided 2.4 times the control bandwidth as compared to the original FIR designs. Here the authors demonstrate the performance of the designed filters using transient diagnostic measurements from ALS and DAPNE.

    2017-01-01

    The aim of the MD was to study the controlled longitudinal emittance blow-up applied during the ramp with bunches that are slightly shorter than operational. Earlier MDs in 2015 have shown that with a short target bunch length, the blow-up is less controlled and a bifurcation of bunch lengths occurs. The presented measurements show that the bifurcation is independent of the presence of the bunch length feedback, pointing towards an intensity-dependent phenomenon, originating from a synchrotron frequency shift with intensity. Accurate measurements of synchrotron frequency shift with intensity are presented as well. The measurements took place between 22nd August 2016, 19:00 and 23rd August 2016, 04:00.

    To report the first three cases of spontaneous resolution of chalazia after 3 to 5 years. Patients with chalazia who visited Honda Eye Clinic were observed and treated between 1991 and 2008. Chalazia were diagnosed by deliberate palpation of lids and observation of external appearance of lids. Histopathologic examination of excised specimens was performed to confirm the diagnosis. All data were obtained from the regular daily clinical practices and recordings with informed consent. Three chalazia completely resolved without medications or surgical interventions after 3 to 5 years. Excisions of chalazia of patients aged older than 50 years were few. Chalazion may be a self-limiting disorder even in the long-term.

    1992-12-01

    In the face of rising urban travel demand, there is strong public perception that urban mobility in California has seriously deteriorated and that solutions for urban traffic congestion problems are urgently needed. Simply constructing more and more miles of roadways is no longer an acceptable option. Many researchers believe that advanced vehicle longitudinal control systems provide an opportunity to bring about very significant increases in the highway capacity. Longitudinal control systems range from driver-assisted intelligent cruise control systems (ICCS's) to fully automated systems with close-formation platooning. The objectives of this study are to identify strategies for early deployment of longitudinal control technologies on the highway, and to evaluate potential impacts of these strategies on traffic operation, highway capacity, and traffic accidents.

    Study Objectives: Previous case reports of intravenous immunoglobulins (IVIg) in pediatric narcolepsy have shown contradictory results. Methods: This was a nonrandomized, open-label, controlled, longitudinal observational study of IVIg use in pediatric narcolepsy with retrospective data collection from medical files obtained from a single pediatric national reference center for the treatment of narcolepsy in France. Of 56 consecutively referred patients with narcolepsy, 24 received IVIg (3 infusions administered at 1-mo intervals) in addition to standard care (psychostimulants and/or anticataplectic agents), and 32 continued on standard care alone (controls). Results: For two patients in each group, medical files were unavailable. Of the 22 IVIg patients, all had cerebrospinal fluid (CSF) hypocretin ≤ 110 pg/mL and were HLA-DQB1*06:02 positive. Of the 30 control patients, 29 were HLA-DQB1*06:02 positive and of those with available CSF measurements, all 12 had hypocretin ≤ 110 pg/mL. Compared with control patients, IVIg patients had shorter disease duration, shorter latency to sleep onset, and more had received H1N1 vaccination. Mean (standard deviation) follow-up length was 2.4 (1.1) y in the IVIg group and 3.9 (1.7) y in controls. In multivariate-adjusted linear mixed-effects analyses of change from baseline in Ullanlinna Narcolepsy Scale (UNS) scores, high baseline UNS, but not IVIg treatment, was associated with a reduction in narcolepsy symptoms. On time-to-event analysis, among patients with high baseline UNS scores, control patients achieved a UNS score narcolepsy symptoms were not significantly reduced by IVIg. However, in patients with high baseline symptoms, a subset of IVIg-treated patients achieved remission more rapidly than control patients.

    Selected Reaction Monitoring (SRM) is a powerful tool for targeted detection and quantification of peptides in complex matrices. An important objective of SRM is to obtain peptide quantifications that are (1) suitable for the investigation, and (2) reproducible across laboratories and runs. The first objective is achieved by system suitability tests (SST), which verify that mass spectrometric instrumentation performs as specified. The second objective is achieved by quality control (QC), which provides in-process quality assurance of the sample profile. A common aspect of SST and QC is the longitudinal nature of the data. Although SST and QC have received a lot of attention in the proteomic community, the currently used statistical methods are limited. This manuscript improves upon the statistical methodology for SST and QC that is currently used in proteomics. It adapts the modern methods of longitudinal statistical process control, such as simultaneous and time weighted control charts and change point analysis, to SST and QC of SRM experiments, discusses their advantages, and provides practical guidelines. Evaluations on simulated data sets, and on data sets from the Clinical Proteomics Technology Assessment for Cancer (CPTAC) consortium, demonstrated that these methods substantially improve our ability of real time monitoring, early detection and prevention of chromatographic and instrumental problems. We implemented the methods in an open-source R-based software package MSstatsQC and its web-based graphical user interface. They are available for use stand-alone, or for integration with automated pipelines. Although the examples focus on targeted proteomics, the statistical methods in this manuscript apply more generally to quantitative proteomics. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

    Few studies of breast cancer surgery outcomes have used longitudinal data for more than 2 years. This study aimed to validate the use of the artificial neural network (ANN) model to predict the 5-year mortality of breast cancer patients after surgery and compare predictive accuracy between the ANN model, multiple logistic regression (MLR) model, and Cox regression model. This study compared the MLR, Cox, and ANN models based on clinical data of 3632 breast cancer patients who underwent surgery between 1996 and 2010. An estimation dataset was used to train the model, and a validation dataset was used to evaluate model performance. The sensitivity analysis was also used to assess the relative significance of input variables in the prediction model. The ANN model significantly outperformed the MLR and Cox models in predicting 5-year mortality, with higher overall performance indices. The results indicated that the 5-year postoperative mortality of breast cancer patients was significantly associated with age, Charlson comorbidity index (CCI), chemotherapy, radiotherapy, hormone therapy, and breast cancer surgery volumes of hospital and surgeon (all P < 0.05). Breast cancer surgery volume of surgeon was the most influential (sensitive) variable affecting 5-year mortality, followed by breast cancer surgery volume of hospital, age, and CCI. Compared with the conventional MLR and Cox models, the ANN model was more accurate in predicting 5-year mortality of breast cancer patients who underwent surgery. The mortality predictors identified in this study can also be used to educate candidates for breast cancer surgery with respect to the course of recovery and health outcomes.

    An integrated semi-active seat suspension for both longitudinal and vertical vibration control is analyzed and tested in this paper. The seat suspension consists of a switching mechanism transforming both longitudinal and vertical motions into a rotary motion and a real-time damping-controllable system-a rotary magnetorheological (MR) damper working in pure shear mode and its corresponding control system. The switching mechanism employs the parallelogram frames as a motion guide which keeps the seat moving longitudinally and vertically. At the same time, both longitudinal and vertical motions are transformed into a reciprocating rotary motion that is transmitted to the rotary MR damper after an amplification by a gear mechanism. Both the longitudinal and vertical vibrations can be attenuated in real time through controlling the damping force (or torque) of the rotary MR damper. The mathematical model of the seat suspension system is established, simulated, and analyzed. The experimental test based on the test rig in Hefei University of Technology is implemented, and the results of simulation and experimental test are compared and analyzed.

    We report on the experimental generation of relativistic electron bunches with a tunable longitudinal bunch shape. A longitudinal bunch-shaping (LBS) beam line, consisting of a transverse mask followed by a transverse-to-longitudinal emittance exchange (EEX) beam line, is used to tailor the longitudinal bunch shape (or current profile) of the electron bunch. The mask shapes the bunch's horizontal profile, and the EEX beam line converts it to a corresponding longitudinal profile. The Argonne wakefield accelerator rf photoinjector delivers electron bunches into a LBS beam line to generate a variety of longitudinal bunch shapes. The quality of the longitudinal bunch shape is limited by various perturbations in the exchange process. We develop a simple method, based on the incident slope of the bunch, to significantly suppress the perturbations.

    A sample of children, initially 12 years old, in the People's Republic of China participated in this 2-year longitudinal study. Data on parental warmth, control, and indulgence were collected from children's self-reports. Information concerning social, academic, and psychological adjustment was obtained from multiple sources. The results indicated that parenting styles might be a function of child gender and change with age. Regression analyses revealed that parenting styles of fathers and mothers predicted different outcomes. Whereas maternal warmth had significant contributions to the prediction of emotional adjustment, paternal warmth significantly predicted later social and school achievement. It was also found that paternal, but not maternal, indulgence significantly predicted children's adjustment difficulties. The contributions of the parenting variables might be moderated by the child's initial conditions.

    People with diabetes and poor glycaemic control are at higher risk of diabetes-related complications and incur higher healthcare costs. An understanding of the sociodemographic and clinical characteristics associated with poor glycaemic control is needed to overcome the barriers to achieving care goals in this population. We used linked administrative and laboratory data to create a provincial cohort of adults with prevalent diabetes, and a measure of HbA1c that occurred at least 1 year following the date of diagnosis. The primary outcome was poor glycaemic control, defined as at least two consecutive HbA1c measurements ≥ 86 mmol/mol (10%), not including the index measurement, spanning a minimum of 90 days. We used multivariable Cox proportional hazards models to evaluate the association between baseline sociodemographic and clinical factors and poor glycaemic control. In this population-based cohort of 169 890 people, younger age was significantly associated with sustained poor glycaemic control, with a hazard ratio (HR) of 3.08, 95% CI (2.79-3.39) for age 18-39 years compared with age ≥ 75 years. Longer duration of diabetes, First Nations status, lower neighbourhood income quintile, history of substance abuse, mood disorder, cardiovascular disease, albuminuria and high LDL cholesterol were also associated with poor glycaemic control. Although our results may be limited by the observational nature of the study, the large geographically defined sample size, longitudinal design and robust definition of poor glycaemic control are important strengths. These findings demonstrate the complexity associated with poor glycaemic control and indicate a need for tailored interventions. © 2015 Diabetes UK.

    Cognitive control is the process of employing executive functions, such as attention, planning or working memory, to guide appropriate behaviors in order to achieve a specific goal. Functional magnetic resonance imaging studies suggest a superordinate cognitive control network, comprising the dorsal regions of the lateral prefrontal cortex (DLPFC), anterior cingulate cortex (dACC) and parietal cortex (DPC). How gray matter structure changes across this network throughout neurodevelopment and how these changes impact cognitive control are not yet fully understood. Here we investigate changes in gray matter volume of the key nodes of the cognitive control network using structural MRI scans from 176 participants aged 8-38 years. One hundred and eleven of these also completed a longitudinal follow-up at two years. We compare these with performance on a cognitive battery also measured at these two time points. We found that volume decreases in the cognitive control network were associated with improved performance in executive function (in left DLPFC and bilateral DPC), information processing (in bilateral dACC and right DPC) and emotion identification tasks (left DLPFC). These results were significant after controlling for age. Furthermore, gray matter changes were coordinated across the network. These findings imply age-independent synaptic pruning in the cognitive control network may have a role in improving performance in cognitive domains. This study provides insight into the direct impact of structural changes on behavior within this network during neurodevelopment and provides a normative evidence base to better understand development of cognitive dysfunction in brain disorders.

On time-to-event analysis, among patients with high baseline UNS scores, control patients achieved a UNS score treatment response in any analysis. Overall, narcolepsy symptoms were not significantly reduced by IVIg. However, in patients with high baseline symptoms, a subset of IVIg-treated patients achieved remission more rapidly than control patients.

    Disturbances in skeletal status in subjects with genetic disorder may increase their fracture risk. The aim of the study was longitudinal observation of phalangeal speed of sound changes across the bone over a period of 2 y in 24 patients (14 boys and 10 girls, mean age 9.63 +/- 1.8 y.) and 24 age-matched healthy controls (14 boys and 10 girls, mean age 9.65 +/- 1.71 y.). Weight and height did not differ between patients and controls at baseline and follow-up. Patients with the following disorders were evaluated: 7 with Down syndrome, 6 nonspecific mental retardations of unknown etiology, 5 Martin-Bell syndrome and 6 with other diseases. In patients and controls, no factors potentially influencing bone metabolism (except for genetic disorder) were present. Bone status was assessed by quantitative ultrasound at hand phalanges using DBM Sonic 1200 (IGEA, Carpi, Italy), which measures amplitude-dependent speed of sound (Ad-SoS [m/s]). At baseline, Ad-SoS and Z-score were significantly lower in patients than in controls (1892 +/- 51 m/s versus 1936 +/- 43 m/s, p Z-score increased significantly in patients (1892 +/- 51 m/s to 1934 +/- 48 m/s, p Z-Score were significantly lower in patients (p Z-score weight did not differ between patients and control, and height increased more in controls (13.2 +/- 2.8 cm versus 11.4 +/- 5.9 cm, p over a period of observation. In conclusion, despite comparable improvement in measured ultrasound parameter in patients and controls observed over a study duration, the difference between them remained stable.

    Full Text Available ABSTRACT Objective To ascertain whether modifiable physical performance–based measurements predicted 5.5-year mortality in a riparian elderly cohort in the Amazon rainforest region. Methods A longitudinal study evaluating the impact of functional determinants on 5.5-year mortality in a riparian elderly cohort from Maués City in the state of Amazonas, Brazil, was performed. The study was a follow-up of a previous observational investigation that evaluated various fitness tests in 630 Amazonian riparian elderly (291 males and 339 females aged 72.3 ± 8.0 (60–99 years old. The cohort was selected for its adverse environmental conditions, which increased the risk of falls yet required maintenance of good physical condition for carrying out relatively rigorous daily activities, and restricted access to specialized health services. Official death records were obtained from the Maués Municipal Health Department. Results A total of 80 study participants (12.7% died over the 5.5-year study period. Kaplan-Meier regression analysis showed significant association between Timed Up and Go (TUG test scores ≥ 14 seconds and mortality risk, independent of sex, age, and other health variables. Conclusions The study results suggest that the TUG test can be used as an indicator for initiating therapeutic and preventive actions, including conducting exercises or physical activities adapted to the health and functional conditions of the elderly, by identifying elderly people with a higher relative risk of mortality.

    An investigation of approach and landing longitudinal flying qualities, based on data generated using a variable stability NT-33 aircraft combined with significant control system dynamics is described. An optimum pilot lead time for pitch tracking, flight path angle tracking, and combined pitch and flight path angle tracking tasks is determined from a closed loop simulation using integral squared error (ISE) as a performance measure. Pilot gain and lead time were varied in the closed loop simulation of the pilot and aircraft to obtain the best performance for different control system configurations. The results lead to the selection of an optimum lead time using ISE as a performance criterion. Using this value of optimum lead time, a correlation is then found between pilot rating and performance with changes in the control system and in the aircraft dynamics. It is also shown that pilot rating is closely related to pilot workload which, in turn, is related to the amount of lead which the pilot must generate to obtain satisfactory response. The results also indicate that the pilot may use pitch angle tracking for the approach task and then add flight path angle tracking for the flare and touchdown.

    Dengue hemorrhagic fever is transmitted through a bite by a dengue -infected Aedes aegypti mosquito. It was first reported in the mid -20th century in Thailand, and since then its epidemiology has been of great concern and has spread all across the country. The alarming incidence of dengue posed a serious threat to human health in all major cities of Thailand. This study was aimed at identifying the level of awareness of dengue fever in Thai population knowledge for prevention and control, and most importantly contribution of media in educating masses for dengue control measures. It is longitudinal in nature and was conducted in 25 provinces of Thailand during 2013-2015. Approximately 7772 respondents participated in this study, with the selection of provinces based on considerations like population, prevalence and demography. A pre-tested structured questionnaire was used to collect information relevant to study participants' demographic profile, pre-existing knowledge about dengue fever and its reinforcement through media, and population attitudes toward prevention and control. Over the period of three years, a positive trend was revealed relevant to the contribution of media in educating and reminding the Thai population of dengue, without any uniformity or powerful campaigns. Based on the results drawn from this study, we conclude that despite the measures undertaken to prevent dengue fever, there is insufficient media exposure. An interdisciplinary approach involving the community participation, media, and government is needed to overcome dengue threat in Thailand. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    Students' well-being is very important both for students and institutions. However, this field lacks longitudinal research, which focuses on the change of nursing students' well-being during their study. In order to asses such changes the four study types according to Job-Demand-Control-Support-model were used: passive, high-strain, low-strain, and active. A longitudinal design was employed: participants were recruited in 2010/2011 (phase I) and at the end of their study in 2012 (phase II). The study was performed in one school of health care in a university of applied sciences in Finland. The final sample consisted of 135 nursing students (BSc) who started their study either in September 2008 or January 2009, and finished in December 2011 or May 2012. The participants responded to the same close-ended questionnaire in both phases. The majority of the participants experienced the study type as low-strain (phase I: 61.5%; phase II: 48.2%). The distribution according to their study type did not change substantially between both phases, although 42.2% of the participants changed their study type. The major changes of study types were from low-strain to others (21.4%), and from other study types to the active one (12.6%). The results indicate that the majority of students do not change their study type and consequentially their well-being during their study, which is in contrast with previous research. Special attention should be put to the identification of students who change their study type to high-strain or remain in it. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Fulfilling handling qualities still remains a challenging problem during flight control design. These criteria of different nature are derived from a wide experience based upon flight tests and data analysis, and they have to be considered if one expects a good behaviour of the aircraft. The goal of this thesis is to develop synthesis methods able to satisfy these criteria with fixed classical architectures imposed by the manufacturer or with a new flight control architecture. This is applied to the longitudinal flight model of a Bombardier Inc. business jet aircraft, namely the Challenger 604. A first step of our work consists in compiling the most commonly used handling qualities in order to compare them. A special attention is devoted to the dropback criterion for which theoretical analysis leads us to establish a practical formulation for synthesis purpose. Moreover, the comparison of the criteria through a reference model highlighted dominant criteria that, once satisfied, ensure that other ones are satisfied too. Consequently, we are able to consider the fulfillment of these criteria in the fixed control architecture framework. Guardian maps (Saydy et al., 1990) are then considered to handle the problem. Initially for robustness study, they are integrated in various algorithms for controller synthesis. Incidently, this fixed architecture problem is similar to the static output feedback stabilization problem and reduced-order controller synthesis. Algorithms performing stabilization and pole assignment in a specific region of the complex plane are then proposed. Afterwards, they are extended to handle the gain-scheduling problem. The controller is then scheduled through the entire flight envelope with respect to scheduling parameters. Thereafter, the fixed architecture is put aside while only conserving the same output signals. The main idea is to use Hinfinity synthesis to obtain an initial controller satisfying handling qualities thanks to reference model

    Full Text Available Abstract Background Diabetes is the sixth leading cause of death and results in significant morbidity. The purpose of this study is to determine what demographic, health status, treatment, access/quality of care, and behavioral factors are associated with poor glycemic control in a Type 2 diabetic, low-income, minority, San Diego population. Methods Longitudinal observational data was collected on patients with Type 2 diabetes from Project Dulce, a program in San Diego County designed to care for an underserved diabetic population. The study sample included 573 patients with a racial/ethnic mix of 53% Hispanic, 7% black, 18% Asian, 20% white, and 2% other. We utilized mixed effects models to determine the factors associated with poor glycemic control using hemoglobin A1C (A1C as the outcome of interest. A multi-step model building process was used resulting in a final parsimonious model with main effects and interaction terms. Results Patients had a mean age of 55 years, 69% were female, the mean duration of diabetes was 7.1 years, 31% were treated with insulin, and 57% were obese. American Diabetes Association (ADA recommendations for blood pressure and total cholesterol were met by 71% and 68%, respectively. Results of the mixed effects model showed that patients who were uninsured, had diabetes for a longer period of time, used insulin or multiple oral agents, or had high cholesterol had higher A1C values over time indicating poorer glycemic control. The younger subjects also had poorer control. Conclusion This study provides factors that predict glycemic control in a specific low-income, multiethnic, Type 2 diabetic population. With this information, subgroups with high risk of disease morbidity were identified. Barriers that prevent these patients from meeting their goals must be explored to improve health outcomes.

    The purpose of this investigation was to study subjective symptoms, medical and social situation, pulmonary function and physical work capacity during a period of 3-5 years in patients with the postpolio syndrome. We evaluated 68 patients consecutively admitted to our hospital because of postpolio syndrome, and re-evaluated 63 of the same patients 3-5 years later, 43 women and 20 men with mean age 55 +/- 10 (1 SD) years at the second evaluation. The patients answered a questionnaire about their subjective symptoms and medical and social situation, and underwent spirometry as well as symptom-limited exercise stress testing. Most patients experienced increasing symptoms and physical disability related to their polio, while the majority reported that their mental health were unchanged or improved. The lung function was in average moderately reduced of restrictive type, and only minor changes were found during the 3-5 years. A pronounced reduction in peak oxygen uptake was seen at the first evaluation, especially in women. At the second examination, peak oxygen uptake was further decreased, especially in men, more than predicted from increasing age. The patients increased their body mass index significantly during the same period. These results indicate that subjective symptoms and physical disability related to polio increased with increasing age in these patients with the post-polio syndrome, and cardiorespiratory deconditioning and weight gain also became increasing problems in most patients. However, the mental status of the patients remained stable or improved, possibly due to our comprehensive re-rehabilitation and educational programme.

    The incidence of cutaneous melanoma (CM) continues to rise in Ireland. Despite significant advances in melanoma molecular therapy, surgery remains the mainstay of treatment for CM. The University Hospital Waterford (UHW) prospectively maintained CM registry was established in 2010. To summarize 5-year experience (2010-2015) of primary CM presenting to UHW. Data were retrospectively obtained from a central electronic pathology and radiology repository augmented by HIPE data and theatre logs. Data collected included patient demographics and clinico-pathological characteristics, specimen number, size, anatomical location, melanoma subtype, Breslow thickness, Clark's level, ulceration, and mitosis. 592 CMs were managed in UHW during the study period. Overall, females comprised the majority of cases with mean age at presentation 60.78 ± 18.29 years. The most commonly affected anatomical location was the lower limb (26.7%) followed by the back (15.1%), upper limb (15.07%), and face (14.40%). Superficial spreading and lentigo maligna were the most common histological subtype accounting for 19.8 and 20%, respectively. Overall, the mean Breslow depth was 2.4 ± 3.7 mm with corresponding Clark's Level III. Sentinel lymph node positivity was 39/103 (37.89%) most commonly located in the axilla (53.8%) and groin (30.7%). There has been a steady increase in the number of cutaneous melanoma presentations over the past 5-years to the South East Cancer Centre. Patients are managed best by prompt surgical excision and multidisciplinary management. Our results are in keeping with international standards and work continues in determining overall 5-year survival and recurrence rates.

    2014-05-01

    The study aimed to examine shiftworkers fatigue and the longitudinal relationships that impact on fatigue such as team climate, work life conflict, control of shifts and shift type in shift working nurses. We used a quantitative survey methodology and analysed data with a moderated hierarchical multiple regression. After matching across two time periods 18 months apart, the sample consisted of 166 nurses from one Australian hospital. Of these nurses, 61 worked two rotating day shifts (morning & afternoon/evening) and 105 were rotating shiftworkers who worked three shifts (morning afternoon/evening and nights). The findings suggest that control over shift scheduling can have significant effects on fatigue for both two-shift and three-shift workers. A significant negative relationship between positive team climate and fatigue was moderated by shift type. At both Time 1 and Time 2, work life conflict was the strongest predictor of concurrent fatigue, but over time it was not. Copyright © 2013 Elsevier Ltd and The Ergonomics Society.

    Breakfast-eating frequency declines through adolescence and has been inversely associated with body weight in cross-sectional studies, with few prospective studies on this topic. This study was conducted to examine the association between breakfast frequency and 5-year body weight change in 2216 adolescents. Project EAT (Eating Among Teens) was a 5-year longitudinal study of eating patterns and weight concerns among adolescents. Surveys were completed in 1998-1999 (time 1) and 2003-2004 (time 2). Multivariable linear regression was used to examine the association between breakfast frequency and change in BMI, with adjustment for age, socioeconomic status, race, physical activity, time 1 BMI and breakfast category, and time 1 dietary and weight-related variables. At time 1, frequency of breakfast was directly associated with intake of carbohydrate and fiber, socioeconomic status, white race, and physical activity and inversely associated with smoking and alcohol consumption and dieting and weight-control behaviors. In cross-sectional analyses at times 1 and 2, inverse associations between breakfast frequency and BMI remained largely independent of all of the confounding and dietary factors. Weight-related factors (concerns, behaviors, and pressures) explained little of the breakfast-BMI association. In prospective analyses, frequency of breakfast was inversely associated with BMI in a dose-response manner. Further adjustment for confounding and dietary factors did not seem to explain the association, but adjustment for weight-related variables seemed to partly explain this finding. Although experimental studies are needed to verify whether the association between breakfast and body weight is of a causal nature, our findings support the importance of promoting regular breakfast consumption among adolescents. Future studies should further examine the role of breakfast habits among youth who are particularly concerned about their weight.

    This study examined relationships between excess body weight (EBW) loss and current gait and functional status in women 5 years after Roux-en-Y gastric bypass surgery. Gait data were analyzed in nine female bariatric patients for relationships with longitudinal changes in weight, body composition, and physical function assessed by the Short Musculoskeletal Functional Assessment (SMFA) questionnaire and the timed "get-up-and-go" (TGUG) test. Gait characteristics in the bariatric sample were also compared to an age- and BMI-matched nonsurgical reference sample from the Fels Longitudinal Study. Bariatric patients lost an average of 36.4 kg (61.1%) of EBW between preoperative and 5-year follow-up visits (P weight, not preoperative obesity, suggesting that substantial, sustained recovery of physical function is possible with rapid surgical weight loss.

    Full Text Available The use of antipsychotics in very young children is of concern given the lack of empirical evidence in their efficacy and long-term impact on children’s health. This study examined the prescription of antipsychotics among children aged ≤5 years enrolled in a state Medicaid program. Secondary data analysis was conducted using the Medicaid administrative data of a southeastern state. Using SAS 9.3, descriptive statistics were performed to examine socio-demographic characteristics, psychiatric diagnoses, off-label use, receipt of medications from multiple psychotropic drug classes, and receipt of non-pharmacologic psychiatric services among children aged ≤5 years who received antipsychotic prescriptions in calendar year (CY 2011. A total of 112 children in the target age group received antipsychotics in CY 2011, the most common prescription being risperidone. The most common listed psychiatric diagnosis was attention deficit hyperactivity disorder. Two in five children received antipsychotics for off-label use. Three in four children also received medications from at least one other psychotropic drug class. More than half did not receive adjunct psychiatric services. State-level policies offering specific guidance and recommendations for antipsychotic use among very young children are urgently needed. Future research is warranted to examine long-term impact of such practices on children’s growth and development.

    This prospective study was designed to assess the long-term outcome of immediately loaded zygomatic implants placed in atrophic maxillae. Forty-two consecutively treated patients received 81 zygomatic implants and 140 conventional implants for oral rehabilitation and were followed for 5 years. Complete arch rehabilitation was accomplished in 37 patients and partial arch rehabilitation in 5 (one zygomatic implant in combination with two conventional implants). Outcome measures were prosthetic and implant failures, and complications. Twelve zygomatic and 22 conventional implants in 6 patients were not reviewed as patients were lost to follow-up. One zygomatic implant was removed at the 3-year follow-up visit because of lack of osseointegration and disturbances around the zygomatic region. The success rate of zygomatic implants was 98.5% (68/69). Six conventional implants were lost, with a success rate of 94.9% (112/118). One of the definitive prostheses was changed after 4 years of follow-up. Six complications occurred during the entire follow-up period. The 5-year prognosis was found to be good for immediately loaded zygomatic implants together with conventional implants in severely resorbed maxillae.

    We previously confirmed the non-inferiority of accelerated partial breast irradiation (APBI) with interstitial brachytherapy in terms of local control and overall survival compared with whole-breast irradiation for patients with early-stage breast cancer who underwent breast-conserving surgery in a phase 3 randomised trial. Here, we present the 5-year late side-effects and cosmetic results of the trial. We did this randomised, controlled, phase 3 trial at 16 centres in seven European countries. Women aged 40 years or older with stage 0-IIA breast cancer who underwent breast-conserving surgery with microscopically clear resection margins of at least 2 mm were randomly assigned 1:1, via an online interface, to receive either whole-breast irradiation of 50 Gy with a tumour-bed boost of 10 Gy or APBI with interstitial brachytherapy. Randomisation was stratified by study centre, menopausal status, and tumour type (invasive carcinoma vs ductal carcinoma in situ), with a block size of ten, according to an automated dynamic algorithm. Patients and investigators were not masked to treatment allocation. The primary endpoint of our initial analysis was ipsilateral local recurrence; here, we report the secondary endpoints of late side-effects and cosmesis. We analysed physician-scored late toxicities and patient-scored and physician-scored cosmetic results from the date of breast-conserving surgery to the date of onset of event. Analysis was done according to treatment received (as-treated population). This trial is registered with ClinicalTrials.gov, number NCT00402519. Between April 20, 2004, and July 30, 2009, we randomly assigned 1328 women to receive either whole-breast irradiation (n=673) or APBI with interstitial brachytherapy (n=655); 1184 patients comprised the as-treated population (551 in the whole-breast irradiation group and 633 in the APBI group). At a median follow-up of 6·6 years (IQR 5·8-7·6), no patients had any grade 4 toxities, and three (cosmetic

    This serological follow up study assessed the kinetics of antibody response in children who previously participated in a single centre, open-label, randomised controlled trial of low-dose compared to standard-dose diphtheria booster preschool vaccinations in the United Kingdom (UK). Children had previously been randomised to receive one of three combination vaccines: either a combined adsorbed tetanus, low-dose diphtheria, 5-component acellular pertussis and inactivated polio vaccine (IPV) (Tdap-IPV, Repevax(®); Sanofi Pasteur MSD); a combined adsorbed tetanus, low-dose diphtheria and 5-component acellular pertussis vaccine (Tdap, Covaxis(®); Sanofi Pasteur MSD) given concomitantly with oral polio vaccine (OPV); or a combined adsorbed standard-dose diphtheria, tetanus, 2-component acellular pertussis and IPV (DTap-IPV, Tetravac(®); Sanofi Pasteur MSD). Blood samples for the follow-up study were taken at 1, 3 and 5 years after participation in the original trial (median, 5.07 years of age at year 1), and antibody persistence to each vaccine antigen measured against defined serological thresholds of protection. All participants had evidence of immunity to diphtheria with antitoxin concentrations greater than 0.01IU/mL five years after booster vaccination and 75%, 67% and 79% of children who received Tdap-IPV, Tdap+OPV and DTap-IPV, respectively, had protective antitoxin levels greater than 0.1IU/mL. Long lasting protective immune responses to tetanus and polio antigens were also observed in all groups, though polio responses were lower in the sera of those who received OPV. Low-dose diphtheria vaccines provided comparable protection to the standard-dose vaccine and are suitable for use for pre-school booster vaccination. Copyright © 2015 The Authors.

    This study, which is part of a larger longitudinal study focusing on the biopsychosocial functioning of emerging adults with type 1 diabetes, examined how perceived personal control, coping and HbA1c relate to one another over time. Emerging adults with type 1 diabetes (18-30 years old) participated in a two-wave longitudinal study spanning five years (N = 164 at Time 1). At both times, patients completed questionnaires on perceived control and coping (i.e. diabetes integration, avoidant coping and passive resignation). HbA1c values were obtained from treating clinicians. We investigated the directionality of effects using cross-lagged path analysis. Higher HbA1c values predicted relative decreases in diabetes integration and increases in avoidant coping five years later. Feeling less in control over diabetes predicted the use of passive coping over time. Passive coping predicted a relative decrease in perceived control five years later. These findings indicate that tackling poor glycaemic control is not only important to avoid medical complications but also to prevent patients from resorting to more avoidant coping strategies. Furthermore, given the longitudinal interplay between perceived control and passive coping, it is important that intervention efforts include both cognitive and behavioural components to be effective.

    Home visits (HV) provide excellent opportunities for health promotion. This longitudinal study compared the effects of HV and telephone contacts (TC) in preventing early childhood caries (ECC) and colonisation of mutans streptococci (MS) and lactobacilli (LB) from 0 to 24 months. A total of 325 children were recruited from community health centres at mean age of 42 days, and randomly assigned to receive either HV or TC. A total of 188 children completed three, 6 monthly HV, and another 58 had three, 6 monthly TC. An additional 40 age-matched children from childcare facilities served as reference controls (RC). At 24 months, all groups were examined at a community dental clinic. At 24 months, three HV children of 188 (1.5%) had caries, compared to four TC of 58 (6.8%) and nine RC of 40 (22.5%) (P < 0.001 for HV versus RC; P = 0.05 for HV versus TC and P = 0.03 for TC versus RC). There were also more children with MS in the TC (47%) and RC (35%) compared to HV (28%) group (P = 0.01 and P = 0.02). Home visits and telephone contacts conducted 6 monthly from birth are effective in reducing ECC prevalence by 24 months. © 2012 The Authors.

    Science.gov (United States)

    Fiala, Clare; Diamandis, Eleftherios P

    2017-10-14

    We discuss in depth six causes of scientific irreproducibility and their ramifications for the clinical sciences: fraud, unfounded papers published by prominent authorities, bias, technical deficiencies, fragmented science and problems with big data. Some proposed methods to combat this problem are briefly described, including an effort to replicate results from some high impact papers and a proposal that authors include detailed preclinical data in papers with supposedly high translational value. We here advocate for a 5-year reflection on papers with seemingly high clinical/translational potential, published alongside the original paper where authors reflect on the quality, reproducibility and impact of their findings. These reflections can be used as a benchmark for credibility, and begin a virtuous cycle of improving the quality of published findings in the literature.

    The comprehension of constituent questions is an important topic for language acquisition research and for applications in the diagnosis of language impairment. This article presents the results of a study investigating the comprehension of different types of questions by 5-year-old, typically...... developing children across 19 European countries, 18 different languages, and 7 language (sub-)families. The study investigated the effects of two factors on question formation: (a) whether the question contains a simple interrogative word like ‘who’ or a complex one like ‘which princess’, and (b) whether...... the question word was related to the sentential subject or object position of the verb. The findings show that there is considerable variation among languages, but the two factors mentioned consistently affect children’s performance. The cross-linguistic variation shows that three linguistic factors facilitate...

    In pulsar timing, timing residuals are the differences between the observed times of arrival and predictions from the timing model. A comprehensive timing model will produce featureless residuals, which are presumably composed of dominating noise and weak physical effects excluded from the timing model (e.g. gravitational waves). In order to apply optimal statistical methods for detecting weak gravitational wave signals, we need to know the statistical properties of noise components in the residuals. In this paper we utilize a variety of non-parametric statistical tests to analyze the whiteness and Gaussianity of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) 5-year timing data, which are obtained from Arecibo Observatory and Green Bank Telescope from 2005 to 2010. We find that most of the data are consistent with white noise; many data deviate from Gaussianity at different levels, nevertheless, removing outliers in some pulsars will mitigate the deviations.

    This study tested whether adolescents who used cannabis or met criteria for cannabis dependence showed neuropsychological impairment prior to cannabis initiation and neuropsychological decline from before to after cannabis initiation. A longitudinal co-twin control study. Participants were 1989 twins from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally representative birth cohort of twins born in England and Wales from 1994 to 1995. Frequency of cannabis use and cannabis dependence were assessed at age 18. Intelligence quotient (IQ) was obtained at ages 5, 12 and 18. Executive functions were assessed at age 18. Compared with adolescents who did not use cannabis, adolescents who used cannabis had lower IQ in childhood prior to cannabis initiation and lower IQ at age 18, but there was little evidence that cannabis use was associated with IQ decline from ages 12-18. For example, adolescents with cannabis dependence had age 12 and age 18 IQ scores that were 5.61 (t = -3.11, P = 0.002) and 7.34 IQ points (t = -5.27, P cannabis dependence, but adolescents with cannabis dependence did not show greater IQ decline from age 12-18 (t = -1.27, P = 0.20). Moreover, adolescents who used cannabis had poorer executive functions at age 18 than adolescents who did not use cannabis, but these associations were generally not apparent within twin pairs. For example, twins who used cannabis more frequently than their co-twin performed similarly to their co-twin on five of six executive function tests (Ps > 0.10). The one exception was that twins who used cannabis more frequently than their co-twin performed worse on one working memory test (Spatial Span reversed; β = -0.07, P = 0.036). Short-term cannabis use in adolescence does not appear to cause IQ decline or impair executive functions, even when cannabis use reaches the level of dependence. Family background factors explain why adolescent cannabis users perform worse on IQ and executive

    Full Text Available Objectives: Objective of this study was investigating impact of early psychological interventions on marital satisfaction of mothers with slow pace under 5 years children. Considering variables of the research, that is, early psychological interventions and marital satisfaction, research hypotheses was as follows: "early psychological interventions affect marital satisfaction of mothers with slow pace under 5 years children" and it was examined. Methods: This research is of experimental type and pretest-posttest plan with control groups was used. Statistical population included all mothers with slow pace under 5 years children in Urmia. To this end, 40 mothers with slow pace children were selected as the sample in a non-random manner by convenience sampling. They were assigned randomly into two groups of 20 (20 test group and 20 control group, and finally psychological interventions were conducted on one of groups randomly. In order to evaluate marital satisfaction, Enrich marital satisfaction questionnaire with 47 items was used. Data were analyzed by univariate analysis of covariance. Results: findings showed that there is significant difference between two groups in posttest in overall score of marital satisfaction as well as in some elements such as conventional responses, marital satisfaction, personality issues, marital relationships, conflict resolution, leisure, parenting, family and friends, and ideological orientation and sexual relations (P<0.005, and no significant difference was observed in financial supervision and roles related to gender equality. Discusion: Psychological interventions were effective in promoting marital satisfaction in mothers with slow pace under 5 years children.

    Dietary behaviours are substantially influenced by environmental and internal stimuli, such as mood, social situation, and food availability. However, little is known about the role of stimulus control for eating in non-clinical populations, and no studies so far have looked at eating and drinking behaviour simultaneously. 53 individuals from the general population took part in an intensive longitudinal study with repeated, real-time assessments of eating and drinking using Ecological Momentary Assessment. Eating was assessed as main meals and snacks, drinks assessments were separated along alcoholic and non-alcoholic drinks. Situational and internal stimuli were assessed during both eating and drinking events, and during randomly selected non-eating occasions. Hierarchical multinomial logistic random effects models were used to analyse data, comparing dietary events to non-eating occasions. Several situational and affective antecedents of dietary behaviours could be identified. Meals were significantly associated with having food available and observing others eat. Snacking was associated with negative affect, having food available, and observing others eat. Engaging in activities and being with others decreased the likelihood of eating behaviours. Non-alcoholic drinks were associated with observing others eat, and less activities and company. Alcoholic drinks were associated with less negative affect and arousal, and with observing others eat. RESULTS support the role of stimulus control in dietary behaviours, with support for both internal and external, in particular availability and social stimuli. The findings for negative affect support the idea of comfort eating, and results point to the formation of eating habits via cue-behaviour associations. Copyright © 2015 Elsevier Ltd.

    Full Text Available Abstract Background The prevalence of non-communicable diseases (NCDs is increasing worldwide, also among children. Information about primary prevention of NCD’s is increasing; however, convincing strategies among children is needed. The present paper describes the design and methods in the Health Oriented Pedagogical Project (HOPP study. The main objective is to evaluate the effects of a school-based physical activity intervention program on cardio-metabolic risk factors. Secondary objectives include assessment of physical, psychological and academic performance variables. Methods The HOPP study is a 7 years longitudinal large-scale controlled intervention in seven elementary schools (n = 1545 with two control schools (n = 752; all aged 6–11 years at baseline. The school-based physical activity intervention program includes an increase in physical activity (PA of 225 min/week as an integrated part of theoretical learning, in addition to the curriculum based 90 min/week of ordinary PA. Primary outcomes include cardio-metabolic risk factors measured as PA level, BMI status, waist circumference, muscle mass, percent fat, endurance test performance, total serum cholesterol, high-density lipoprotein (HDL, non-HDL, micro C-reactive protein (mCRP and long-term blood sugar (HbA1c. In addition, secondary outcomes include anthropometric growth measures, physical fitness, quality of life (QoL, mental health, executive functions, diet and academic performance. Discussion HOPP will provide evidence of effects on cardio-metabolic risk factors after a long-term PA intervention program in elementary schoolchildren. School-based PA intervention programs may be an effective arena for health promotion and disease prevention. Trial registration The study is registered in Clinical trials (ClinicalTrials.gov Identifier: NCT02495714 as of June 20th – 2015, retrospectively registered. The collection of baseline values was initiated in mid-January 2015.

    Objective Gross motor development in early childhood is important in fostering greater interaction with the environment. The purpose of this study is to describe gross motor skills among US children aged 3-5 years using the Test of Gross Motor Development (TGMD-2). Methods We used 2012 NHANES National Youth Fitness Survey (NNYFS) data, which included TGMD-2 scores obtained according to an established protocol. Outcome measures included locomotor and object control raw and age-standardized scores. Means and standard errors were calculated for demographic and weight status with SUDAAN using sample weights to calculate nationally representative estimates, and survey design variables to account for the complex sampling methods. Results The sample included 339 children aged 3-5 years. As expected, locomotor and object control raw scores increased with age. Overall mean standardized scores for locomotor and object control were similar to the mean value previously determined using a normative sample. Girls had a higher mean locomotor, but not mean object control, standardized score than boys (p  0.05). Conclusions In a nationally representative sample of US children aged 3-5 years, TGMD-2 mean locomotor and object control standardized scores were similar to the established mean. These results suggest that standardized gross motor development among young children generally did not differ by demographic or weight status.

    The aims of this paper were to report on the global psychosocial functioning of 5-year-old DHH children and examine the risk and protective factors that predict outcomes. A cross-sectional analysis of data collected from a prospective, population-based longitudinal study. Parents/caregivers of 356 children completed questionnaires on psychosocial development (CDI, SDQ), functional communication (PEACH) and demographic information. Children completed standardized assessments of non-verbal cognitive ability (WNV) and language (PLS-4). On average, global psychosocial functioning was within the range of typically developing children; however, variability was high and 12% of children had scores that were more than 2 SDs below the norm. Non-verbal cognitive ability, presence of additional disabilities, language and functional communication significantly predicted outcomes. In contrast, type of hearing device, severity of hearing loss and age at intervention did not. The global psychosocial functioning of this cohort of 5-year-old DHH children fell within the range of typically developing children. The findings suggest that spoken language ability and functional communication skills are vital for healthy psychosocial development.

    The first self-reported symptoms of nicotine dependence (e.g., as craving) can appear within days to weeks of the onset of occasional use, and the appearance of symptoms predicts future consumption and dependence. We sought to determine whether craving for alcohol occurs in early stages of adolescent alcohol use, and whether it predicts future binge drinking, a prevalent and problematic behavior. Longitudinal (30-month) four-wave study of 3415 students (M=12.5 years at baseline) from 29 German schools. Students reported five symptoms of alcohol craving on a scale developed based on well-validated measures for tobacco. Multilevel mixed-effects logistic regression was used to predict having five or more binge episodes by last follow-up, based on the number of symptoms reported before the first lifetime binge. Multiple imputation was used to address study drop-out. At baseline, 23% reported at least one symptom, increasing to 54% at wave 4. Any report of symptoms at baseline was associated with frequency of alcohol use, being present in 100% of daily, 93% of weekly, 87% of monthly, 48% of infrequent drinkers, and 16% of ever drinkers reporting no current alcohol use. Moreover, symptoms at baseline independently predicted frequent binge drinking 2.5 years later, AOR=2.08 (95% CI 1.39, 3.11; pbinge drinking. Copyright © 2016 Elsevier Ireland Ltd.

    Proteins are important targets of several modifications caused by oxidative stress, leading to structural changes and consequently partial or total loss of their functions. The oxidized proteins include advanced oxidation protein products (AOPP) derived from oxidation-modified albumin, as well as fibrinogen and lipoproteins. An increase in AOPP levels indicates an oxidative stress state and the presence of coexisting inflammation. Several investigations have also suggested an association between high AOPP levels and aging-related diseases. However, the link between elevated AOPP levels and elderly mortality risk has not yet been investigated. Here, we report on a 5-year longitudinal study that investigated the potential association between AOPP levels and mortality using a population-based representative sample of riparian elders living in Brazilian Amazon region (Maués-AM). Age, sex, socioeconomic and cultural conditions, chronic morbidities, polypharmacy, and previous morbidities were also tested as potential confounders. The AOPP levels were measured in 540 (84.78%) individuals, all of whom were followed over a 5-year period in order to establish the mortality rate. Within this study period, 74 (13.7%) elders died and 466 (86.3%) survived. The AOPP levels were higher among the elders who died within the 5-year period (46.27 ± 40.6 mmol/L) compared with those who survived (36.79 ± 20.84 mmol/L) (p = 0.002). The analysis confirmed the link between high AOPP levels and mortality risk, independent of other intervenient factors. These results suggest that elevated AOPP levels could be used to predict mortality risk in elderly patients.

  11. Effects of incentives, age, and behavior on brain activation during inhibitory control: A longitudinal fMRI study

    Directory of Open Access Journals (Sweden)

    David J. Paulsen

    2015-02-01

    Full Text Available We investigated changes in brain function supporting inhibitory control under age-controlled incentivized conditions, separating age- and performance-related activation in an accelerated longitudinal design including 10- to 22-year-olds. Better inhibitory control correlated with striatal activation during neutral trials, while Age X Behavior interactions in the striatum indicated that in the absence of extrinsic incentives, younger subjects with greater reward circuitry activation successfully engage in greater inhibitory control. Age was negatively correlated with ventral amygdala activation during Loss trials, suggesting that amygdala function more strongly mediates bottom-up processing earlier in development when controlling the negative aspects of incentives to support inhibitory control. Together, these results indicate that with development, reward-modulated cognitive control may be supported by incentive processing transitions in the amygdala, and from facilitative to obstructive striatal function during inhibitory control.

    Catheter ablations have been traditionally performed with the use of fluoroscopic guidance, which exposes the patient and staff to the inherent risks of radiation. We have developed techniques to eliminate the use of fluoroscopy during cardiac ablations and have been performing completely fluoroless catheter ablations on our patients for over 5 years. We present a retrospective analysis of the safety, efficacy, and feasibility data from 500 consecutive patients who underwent nonfluoroscopic catheter ablation, targeting a total of 639 arrhythmias, including atrioventricular reciprocating tachycardia (AVRT), atrioventricular nodal reentrant tachycardia (AVNRT), atrial tachycardia (AT), atrial fibrillation (AF), premature ventricular contractions (PVCs), and ventricular tachycardia (VT). We perform fluoroless ablations using intracardiac electrograms, electroanatomic mapping, and for most cases intracardiac echocardiography. Our experience includes exclusively endocardial cardiac ablations. The mean follow-up was 20.5 months. Recurrence rate for AVRT was 6.5%, for AVNRT 2.5%, for macro-reentrant AT 6.4%, for focal AT 5.4%, for AF 22.6%, for PVC 6.7%, and for VT 21.4%. Major complications occurred in five patients (1.0%); minor complications occurred in three patients (0.6%). No deaths occurred. Fluoroscopy was used in one instance, for 0.3 minutes, to confirm venous access. Completely fluoroless catheter ablations may be routinely performed for all endocardial ablations without compromising safety, efficacy, or procedural duration. © 2017 The Authors.

    Data concerning the long-term efficacy of laparoscopic sleeve gastrectomy in the treatment of morbid obesity remain scarce. In this retrospective, the authors present 5-year follow-up of 30 patients having undergone laparoscopic sleeve gastrectomy. Since 2004, 30 patients underwent laparoscopic sleeve gastrectomy and completed 5 years of follow-up. Five patients were subsequently subjected to laparoscopic Roux-en-Y gastric bypass and were excluded from further analysis. The remaining 25 patients comprised the study population. Mean excess weight loss was 65.2 ± 6.1%, 64.7 ± 5.6%, 62 ± 4.9%, 58.2 ± 5.5%, and 56.4 ± 5.8% for the first 5 years, respectively. There were no deaths, nor any major morbidity. Remission of comorbidities was observed in 40% to 80.9% of cases. Laparoscopic sleeve gastrectomy is a safe and effective means of treatment of morbid obesity both in the short and in the long term. More research is needed to better predict which patient will benefit most from this operation. Copyright © 2015 Elsevier Inc. All rights reserved.

    An increase in the number of internationally adopted children has been observed in the last few years. The country of origin that has experienced a greater increase is Ethiopia. The health of internationally adopted children from Ethiopia has not been extensively assessed to date. The main objective of the study is to determine the prevalence of infectious diseases in children adopted from Ethiopia, and to assess their nutritional status. A prospective, observational cohort study was conducted using the medical records of 251 children adopted from Ethiopia to Spain in the period from Jan 1, 2006 and December 31, 2010. The mean age of the children was 7 months (range 1-120). Abnormalities were detected on physical examination in 56.6%. In 90% of cases the child was less than 5 years-old. Half of the sample had a weight below the third percentile, with some degree of malnutrition in 65% of the children. HIV exposure was not uncommon (4.8%). Low weight and acute gastroenteritis were the main findings in this cohort. Infectious diseases should be systematically assessed. Copyright © 2014 Asociación Española de Pediatría.

    The aim of this longitudinal case-control study was to investigate variables associated with caries development from birth to 36 months. Children (n = 1,017) who were followed up every 6 months from birth to 36 months were grouped into those that developed caries by age 30 and 36 months, respectively, and compared with children without caries. By 30 months (n = 608) there were 24 children (4%) who had caries and an additional 23 developed first caries at 36 months (n = 552), giving a total prevalence of 47 children with caries (9%) at 36 months. Children who showed caries by 30 months were more likely to be mutans streptococci (MS) colonised by 18 months (p = 0.001) compared to those who developed caries at 36 months, and showed the following variables: MS counts of >10(5) CFU/ml at 12 months (p = 0.005), missing enamel (p = 0.001), sugar in pacifier at 18 months (p = 0.02), child sleeping next to mother at 6, 18 and 24 months (p = 0.001 to p = 0.02), and exposure to household cigarette smoke at 24 months (p = 0.02). Caries at 36 months was associated with pregnancy problems (p = 0.024), mother having dental cavitations (p = 0.001) and MS presence at 36 months (adjusted odds ratio, AOR = 0.1, p = 0.01 for counts <10(5) CFU/ml). Caries at both 30 and 36 months was associated with MS presence at 18 months (AOR = 6.3, p = 0.005 and AOR = 4.9, p = 0.01). Children who developed caries by 30 months are colonised by MS at younger ages and with higher MS counts compared with children who develop caries at 36 months. Copyright © 2012 S. Karger AG, Basel.

    Objective To continue evaluation of the long‐term efficacy and safety of eteplirsen, a phosphorodiamidate morpholino oligomer designed to skip DMD exon 51 in patients with Duchenne muscular dystrophy (DMD). Three‐year progression of eteplirsen‐treated patients was compared to matched historical controls (HC). Methods Ambulatory DMD patients who were ≥7 years old and amenable to exon 51 skipping were randomized to eteplirsen (30/50mg/kg) or placebo for 24 weeks. Thereafter, all received eteplirsen on an open‐label basis. The primary functional assessment in this study was the 6‐Minute Walk Test (6MWT). Respiratory muscle function was assessed by pulmonary function testing (PFT). Longitudinal natural history data were used for comparative analysis of 6MWT performance at baseline and months 12, 24, and 36. Patients were matched to the eteplirsen group based on age, corticosteroid use, and genotype. Results At 36 months, eteplirsen‐treated patients (n = 12) demonstrated a statistically significant advantage of 151m (p < 0.01) on 6MWT and experienced a lower incidence of loss of ambulation in comparison to matched HC (n = 13) amenable to exon 51 skipping. PFT results remained relatively stable in eteplirsen‐treated patients. Eteplirsen was well tolerated. Analysis of HC confirmed the previously observed change in disease trajectory at age 7 years, and more severe progression was observed in patients with mutations amenable to exon skipping than in those not amenable. The subset of patients amenable to exon 51 skipping showed a more severe disease course than those amenable to any exon skipping. Interpretation Over 3 years of follow‐up, eteplirsen‐treated patients showed a slower rate of decline in ambulation assessed by 6MWT compared to untreated matched HC.

    : This exploratory 12-week, randomised, double-blind, placebo-controlled, parallel-group, phase 2/3, regulatory multicentre trial was done at 32 hospitals, clinics, and clinical research units in 11 countries in Asia, Europe, and North America. Children aged 1-5 years with at least a 6-month history of persistent...... asthmatic symptoms and a need for inhaled corticosteroids were eligible. Patients were randomly allocated using an interactive voice or web-based response system to receive once-daily tiotropium 2·5 μg, tiotropium 5 μg, or placebo as an add-on to inhaled corticosteroids with or without additional controller....... INTERPRETATION: To our knowledge, our small study is the first to assess the safety and efficacy of tiotropium in children aged 1-5 years with persistent asthmatic symptoms. Tolerability of tiotropium was similar to that of placebo, which is consistent with previous findings in older populations. Although mean...

    To examine how coping styles among patients with multiple sclerosis (MS) change over time and how patients' coping styles after 5 years are associated with disability pension. Seventy-six MS patients and 94 healthy controls were included in this study. The patients were examined at baseline and 5 years later. This included a neurological examination and information on disability pension and a questionnaire assessing coping (the COPE scale). Controls were registered at baseline only. Compared to healthy controls, MS patients were more passive in coping with disease related distress. This was even more pronounced 5 years later. Disability pensioned patients employed more social support, venting of emotions and behavioural disengagement at follow-up. This study shows that patients with MS employ coping styles that may be inadequate and this is not improved by adaption over time. Although patients also use strategies to enhance their lives, these findings suggest that there may be a potential for improving the lives of patients with MS through interventions that may enhance adequate coping with the disease.

    The prevalence of proximal caries in primary molar teeth is high in many countries. (1) To study by means of a split-mouth design the 1- and 2.5-year efficacy of sealing proximal lesions vs. flossing instructions (control) on primary molar teeth. (2) To assess children's behaviour and pain perception during the procedure. Ninety-one 4- to 6-year-old children from Bogotá, Colombia participated. Participants had to have at least two proximal lesions scored according to the following radiographic classification system: radiolucency (1) in enamel outer half, (2) restricted to enamel-dentine junction, or (3) restricted to dentine outer third. Baseline, 1- and 2.5-year follow-up bitewing radiographs were taken. Test and control lesions were randomly selected. After temporary separation test lesions were sealed (adhesive). Parents/caregivers received a flossing leaflet for their children. Progression of the lesions was assessed by means of independent reading of conventional bitewing radiographs. One-year (n = 73) test vs. control lesion progression was 27.4 vs. 50.7%, respectively (p caries baseline data. More than 88% of the participants presented positive to definitively positive behaviour and very low or low pain intensity at both first and second appointments. The sealing technique was superior to flossing instructions both after 1 and 2.5 years of follow-up and the majority of the participants had no anxiety or pain during the treatment.

    2015-02-01

    This longitudinal study tested the same children at three time points: infancy (10.5 months of age), toddlerhood (2.5 years of age), and early childhood (4.5 years of age). At 10.5 months, infants were assessed experimentally with a gaze-following paradigm. At 2.5 years, children's language skills were measured using the MacArthur-Bates Communicative Development Inventories. At 4.5 years, children's explicit theory of mind was assessed with a standard test battery. Analyses revealed that infants with higher gaze-following scores at 10.5 months produced significantly more mental-state words at 2.5 years and that children with more mental-state words at 2.5 years were more successful on the theory-of-mind battery at 4.5 years. These predictive longitudinal relationships remained significant after controlling for general language, maternal education, and nonsocial attention. The results illuminate the bridging role that language plays in connecting infants' social cognition to children's later understanding of others' mental states. The obtained specificity in the longitudinal relations informs theories concerning mechanisms of developmental change. Copyright © 2014 Elsevier Inc. All rights reserved.

    Problem Programs that encourage scholarly activities beyond the core curriculum and traditional biomedical research are now commonplace among US medical schools. Few studies have generated outcome data for these programs. The goal of the present study was to address this gap. Intervention The Scholarly Concentration (SC) Program, established in 2006 at the Warren Alpert Medical School of Brown University, is a 4-year elective program that not only encourages students to pursue scholarly work that may include traditional biomedical research but also seeks to broaden students’ focus to include less traditional areas. We compared characteristics and academic performance of SC students and non-SC students for the graduating classes of 2010–2014. Context Approximately one-third of our students opt to complete an SC during their 4-year undergraduate medical education. Because this program is additional to the regular MD curriculum, we sought to investigate whether SC students sustained the academic achievement of non-SC students while at the same time producing scholarly work as part of the program. Outcome Over 5 years, 35% of students elected to enter the program and approximately 81% of these students completed the program. The parameters that were similar for both SC and non-SC students were age at matriculation, admission route, proportion of undergraduate science majors, and number of undergraduate science courses. Most academic indicators, including United States Medical Licensing Examinations scores, were similar for the two groups; however, SC students achieved more honors in the six core clerkships and were more likely to be inducted into the medical school's two honor societies. Residency specialties selected by graduates in the two groups were similar. SC students published an average of 1.3 peer-reviewed manuscripts per student, higher than the 0.8 manuscripts per non-SC student (p=0.013). Conclusions An elective, interdisciplinary scholarly program with

    Full Text Available Background: Pulmonary nocardiosis is a rare but a life-threatening infection caused by Nocardia spp. The diagnosis is often missed and delayed resulting in delay in appropriate treatment and thus higher mortality. Aim: In this study, we aim to evaluate the clinical spectrum and outcome of patients with pulmonary nocardiosis. Methods: A retrospective, 5-year (2009-2014 review of demographic profile, risk factors, clinical manifestations, imaging findings, treatment, and outcome of patients with pulmonary nocardiosis admitted to a tertiary care hospital. Results: The median age of the study subjects was 54 years (range, 16-76 and majority of them (75% were males. The risk factors for pulmonary nocardiosis identified in our study were long-term steroid use (55.6%, chronic lung disease (52.8%, diabetes (27.8%, and solid-organ transplantation (22.2%. All the patients were symptomatic, and the most common symptoms were cough (91.7%, fever (78%, and expectoration (72%. Almost two-third of the patients were initially misdiagnosed and the alternative diagnosis included pulmonary tuberculosis (n = 7, community-acquired pneumonia (n = 5, lung abscess (n = 4, invasive fungal infection (n = 3, lung cancer (n = 2, and Wegener′s granulomatosis (n = 2. The most common radiographic features were consolidation (77.8% and nodules (56%. The mortality rate for indoor patients was 33% despite treatment. Higher mortality rate was observed among those who had brain abscess (100.0%, HIV positivity (100%, need for mechanical ventilation (87.5%, solid-organ transplantation (50%, and elderly (age > 60 years patients (43%. Conclusion: The diagnosis of pulmonary nocardiosis is often missed and delayed resulting in delay in appropriate treatment and thus high mortality. A lower threshold for diagnosing pulmonary nocardiosis needs to be exercised, in chest symptomatic patients with underlying chronic lung diseases or systemic immunosuppression, for the early diagnosis, and

    Background This study examined relationships between excess body weight (EBW) loss and current gait and functional status in women 5 years after Roux-en-Y gastric bypass surgery. Methods Gait data were analyzed in nine female bariatric patients for relationships with longitudinal changes in weight, body composition, and physical function assessed by the Short Musculoskeletal Functional Assessment (SMFA) questionnaire and the timed “get-up-and-go” (TGUG) test. Gait characteristics in the bariatric sample were also compared to an age- and BMI-matched nonsurgical reference sample from the Fels Longitudinal Study. Results Bariatric patients lost an average of 36.4 kg (61.1 %) of EBW between preoperative and 5-year follow-up visits (P bariatric sample fell within the 95 % confidence intervals of gait/EBW relationships in the reference sample. Conclusions Gait and function 5 years after bariatric surgery were characteristic of current weight, not preoperative obesity, suggesting that substantial, sustained recovery of physical function is possible with rapid surgical weight loss.

    Septic cardiomyopathy is a common finding in septic shock patients. The accepted definition of septic cardiomyopathy is often based on the left ventricular ejection fraction (LVEF). The aim of this study was to determine whether the left ventricular longitudinal systolic function was more sensitive than the LVEF in heart function appraisal of septic shock patients. This was a case-control study conducted at a 40-bed Intensive Care Unit (ICU) of Peking Union Medical College Hospital. Septic shock patients admitted to the ICU were consecutively enrolled in the study group from March 1, 2016 to September 1, 2016. The control group was selected from nonsepsis patients who were admitted to the ICU and were comparable to the study group. Transthoracic echocardiography was performed to obtain the LVEF measurement, mitral annular plane systolic excursion (MAPSE), tissue Doppler velocity measurement of mitral annulus (Sa), and tricuspid annular plane systolic excursion. The study group consisted of 45 septic shock patients. Another 45 nonsepsis patients were selected as the control group. There was no difference in the LVEF between the two groups (64.6% vs. 67.2%, t= -1.426, P= 0.161). MAPSE in the study group was much lower than in the control group (1.2 cm vs. 1.5 cm, t= -4.945, Pstudy group was also lower than in the control group (10.2 cm/s vs. 11.8 cm/s, t = -2.796, P= 0.014). Compared to the LVEF, longitudinal systolic function might be more sensitive in the detection of cardiac depression in septic shock patients. In the heart function appraisal of septic shock patients with a normal ejection fraction, more attention should be given to longitudinal function parameters such as MAPSE and Sa.

    Active perinatal care increases the rate of survival of extremely preterm infants, but there are concerns that improved survival might increase the rate of disabled survivors. To determine the neurodevelopmental outcomes of a national cohort of children 6.5 years of age who had been born extremely preterm (children were assessed and compared with matched controls who had been born at term. Comparison estimates were adjusted for demographic differences. Assessments ended in February 2014, and analysis started thereafter. Cognitive ability was measured with the fourth edition of the Wechsler Intelligence Scale for Children (WISC-IV), and the mean (SD) scores of the children who had been born extremely preterm were compared with those of the controls. Clinical examinations and parental questionnaires were used for diagnosis of cerebral palsy, hearing and vision impairments, and cognition for the children who were not assessed with the WISC-IV. Of 486 eligible infants who were born extremely preterm, 441 (90.7%) were assessed at 6.5 years of age (59 by medical record review only) alongside 371 controls. The adjusted mean (SD) full-scale WISC-IV score was 14.2 (95% CI, 12.1-16.3) points lower for children who had been born extremely preterm than for controls. Cognitive disability was moderate for 18.8% of extremely preterm children and 2.2% of controls (P children and 0.3% of controls (P children and 0.0% of controls (P blindness was observed in 2.0% of extremely preterm children and 0.0% of controls (P children and 0.5% of controls (P = .07). Overall, 36.1% (95% CI, 31.7%-40.6%) of extremely preterm children had no disability, 30.4% (95% CI 26.3%-34.8%) had mild disability, 20.2% (95% CI, 16.6%-24.2%) had moderate disability, and 13.4% (95% CI, 10.5%-16.9%) had severe disability. For extremely preterm children, moderate or severe overall disability decreased with gestational age at birth (adjusted odds ratio per week, 0.65 [95% CI, 0.54-0.79]; P

    This study examines longitudinally the bidirectional influences between maternal parenting (behaviors and parenting stress) and mothers' perceptions of their children's adjustment, in a multivariate approach. Data was gathered from 361 low-income mothers (many with psychiatric diagnoses) reporting on their parenting behavior, parenting stress, and their child's adjustment, in a 2-wave longitudinal study over 5 years. Measurement models were developed to derive 4 broad parenting constructs (involvement, control, rejection, and stress) and 3 child adjustment constructs (internalizing problems, externalizing problems, and social competence). After measurement invariance of these constructs was confirmed across relevant groups and over time, both measurement models were integrated in a single crossed-lagged regression analysis of latent constructs. Multiple reciprocal influences were observed between parenting and perceived child adjustment over time: Externalizing and internalizing problems in children were predicted by baseline maternal parenting behaviors, and child social competence was found to reduce parental stress and increase parental involvement and appropriate monitoring. These findings on the motherhood experience are discussed in light of recent research efforts to understand mother-child bidirectional influences and their potential for practical applications.

    A better understanding of the long-term scope and impact of the co-morbidity with oppositional defiant disorder (ODD) and conduct disorder (CD) in attention deficit hyperactivity disorder (ADHD) youth has important clinical and public health implications. Subjects were assessed blindly at baseline (mean age=10.7 years), 1-year (mean age=11.9 years), 4-year (mean age=14.7 years) and 10-year follow-up (mean age=21.7 years). The subjects' lifetime diagnostic status of ADHD, ODD and CD by the 4-year follow-up were used to define four groups (Controls, ADHD, ADHD plus ODD, and ADHD plus ODD and CD). Diagnostic outcomes at the 10-year follow-up were considered positive if full criteria were met any time after the 4-year assessment (interval diagnosis). Outcomes were examined using a Kaplan-Meier survival function (persistence of ODD), logistic regression (for binary outcomes) and negative binomial regression (for count outcomes) controlling for age. ODD persisted in a substantial minority of subjects at the 10-year follow-up. Independent of co-morbid CD, ODD was associated with major depression in the interval between the 4-year and the 10-year follow-up. Although ODD significantly increased the risk for CD and antisocial personality disorder, CD conferred a much larger risk for these outcomes. Furthermore, only CD was associated with significantly increased risk for psychoactive substance use disorders, smoking, and bipolar disorder. These longitudinal findings support and extend previously reported findings from this sample at the 4-year follow-up indicating that ODD and CD follow a divergent course. They also support previous findings that ODD heralds a compromised outcome for ADHD youth grown up independently of the co-morbidity with CD.

    This study examined the feasibility of a longitudinal design to sonographically measure swelling of the median nerve due to controlled exposure to a work task and to evaluate the relationship of changes in morphology to diagnostic standards. Fifteen macaca fascicularis pinched a lever in various wrist positions at a self-regulated pace (8 hours/day, 5 days/week, 18–20 weeks). Nerve conduction velocity (NCV) and cross-sectional area (CSA) were obtained every two weeks from baseline through working and a 6-week recovery. Trending across all subjects showed that NCV slowed and CSA at the carpal tunnel increased in the working arm, while no changes were observed in CSA either at the forearm or for any measure in the non-working arm. There was a small negative correlation between NCV and CSA in the working arm. This study provides validation that swelling can be observed using a longitudinal design. Longitudinal human studies are needed to describe the trajectory of nerve swelling for early identification of median nerve pathology. PMID:24139197

    Deployment can put soldiers at risk of developing post-traumatic stress symptoms. Despite several longitudinal studies, little is known about the timing of an increase in post-traumatic stress symptoms relative to pre-deployment. Longitudinal studies starting pre-deployment, in which participants are repeatedly measured over time, are warranted to assess the timing of an increase in symptoms to ultimately assess the timing of an increase in treatment demand after deployment. In this large observational cohort study, Dutch military personnel who were deployed to Afghanistan as part of the International Security Assistance Forces between March, 2005, and September, 2008, were assessed for post-traumatic stress symptoms with the Self-Rating Inventory for Post-traumatic Stress Disorder (SRIP) questionnaire. Participants were assessed 1 month before deployment and followed up at 1 month, 6 months, 12 months, 2 years, and 5 years after deployment, with changes in SRIP scores compared with pre-deployment using a mixed model analysis. The primary outcome was the total score of post-traumatic stress symptoms measured with SRIP at pre-deployment and the five follow-up assessments, with a score of 38 used as the cutoff to indicate substantial post-traumatic stress symptoms. Between March, 2005, and September, 2008, 1007 participants were recruited to this study. The results show two important effects of deployment on post-traumatic stress symptoms. A short-term symptom increase within the first 6 months after deployment (symptom increase coefficient for SRIP score vs pre-deployment [β] 0·99, 95% CI 0·50-1·48); and a long-term symptom increase at 5 years after deployment (β 1·67, 1·14-2·20). This study underlines the importance of long-term monitoring of the psychological health of soldiers after deployment because early detection of symptoms is essential to early treatment, which is related to improved psychological health.

    Full Text Available The association between hyperinsulinemia and obesity is well known. However, it is uncertain especially in childhood obesity, if initial fasting hyperinsulinemia predicts obesity, or obesity leads to hyperinsulinemia through insulin resistance.To investigate the predictive effect of fasting plasma insulin on subsequent weight change after a 5-year interval in childhood.424 Children from Da Qing city, China, were recruited at 5 years of age and followed up for 5 years. Blood pressure, anthropometric measurements, fasting plasma insulin, glucose and triglycerides were measured at baseline and 5 years later.Fasting plasma insulin at 5 years of age was significantly correlated with change of weight from 5 to 10 years (ΔWeight. Children in the lowest insulin quartile had ΔWeight of 13.08±0.73 kg compare to 18.39±0.86 in the highest insulin quartile (P<0.0001 in boys, and similarly 12.03±0.71 vs 15.80±0.60 kg (P<0.0001 in girls. Multivariate analysis showed that the predictive effect of insulin at 5 years of age on subsequent weight gain over 5 years remained statistically significant even after the adjustment for age, sex, birth weight, TV-viewing time and weight (or body mass index at baseline. By contrast, the initial weight at 5 years of age did not predict subsequent changes in insulin level 5 years later. Children who had both higher fasting insulin and weight at 5 years of age showed much higher levels of systolic blood pressures, fasting plasma glucose, the homeostasis model assessment for insulin resistance (HOMA-IR and triglycerides at 10 years of age.Fasting plasma insulin at 5 years of age predicts weight gain and cardiovascular risk factors 5 year later in Chinese children of early childhood, but the absolute weight at 5 years of age did not predict subsequent change in fasting insulin.

    Attention-Deficit/Hyperactivity Disorder (ADHD) affects approximately 5% of children worldwide and results in significant impairments in daily functioning. Few community-ascertained samples of children with ADHD have been studied prospectively to identify factors associated with differential outcomes. The Children's Attention Project is the first such study in Australia, examining the mental health, social, academic and quality of life outcomes for children with diagnostically-confirmed ADHD compared to non-ADHD controls. The study aims to map the course of ADHD symptoms over time and to identify risk and protective factors associated with differential outcomes. The sample for this prospective longitudinal study is being recruited across 43 socio-economically diverse primary schools across Melbourne, Australia. All children in Grade 1, the second year of formal schooling (6-8 years), are screened for ADHD symptoms using independent parent and teacher reports on the Conners' 3 ADHD index (~N = 5260). Children screening positive for ADHD by both parent and teacher report, and a matched sample (gender, school) screening negative, are invited to participate in the longitudinal study. At baseline this involves parent completion of the NIMH Diagnostic Interview Schedule for Children IV (DISC-IV) to confirm likely ADHD diagnostic status and identify other mental health difficulties, direct child assessments (cognitive, academic, language and executive functioning; height and weight) and questionnaires for parents and teachers assessing outcomes, as well as a broad range of risk and protective factors (child, parent/family, teacher/school, and socio-economic factors). Families will be initially followed up for 3 years. This study is the first Australian longitudinal study of children with ADHD and one of the first community-based longitudinal studies of diagnostically confirmed children with ADHD. The study's examination of a broad range of risk and protective factors and

    We examined effects of life stress and control beliefs on a constellation of subjective indicators of well-being for older people, including meaning in life, happiness, peace of mind, and positive aging perception. The Chinese cultural background provided the sociocultural milieu for the present study. In a longitudinal study, 301 older Chinese adults completed a questionnaire survey twice, 6 months apart. Regression analyses found that stress caused by major life-changing events (acute) and financial hardship (chronic) were consistent negative predictors of all well-being indicators. Furthermore, primary control belief (tenacious goal pursuit) amplified the negative impacts of life events on happiness and peace of mind. Secondary control belief (submitting to circumstances), in contrast, acted as a buffer that alleviated the deleterious effects of financial hardship on peace of mind and meaning in life. Noting the threats of unfavorable life circumstances and the potency of secondary control belief for older Chinese people, theoretical and cultural implications were discussed.

    Very preterm infants are prone to apnea and have an increased risk of death or disability. Caffeine therapy for apnea of prematurity reduces the rates of cerebral palsy and cognitive delay at 18 months of age. To determine whether neonatal caffeine therapy has lasting benefits or newly apparent risks at early school age. Five-year follow-up from 2005 to 2011 in 31 of 35 academic hospitals in Canada, Australia, Europe, and Israel, where 1932 of 2006 participants (96.3%) had been enrolled in the randomized, placebo-controlled Caffeine for Apnea of Prematurity trial between 1999 and 2004. A total of 1640 children (84.9%) with birth weights of 500 to 1250 g had adequate data for the main outcome at 5 years. Combined outcome of death or survival to 5 years with 1 or more of motor impairment (defined as a Gross Motor Function Classification System level of 3 to 5), cognitive impairment (defined as a Full Scale IQcaffeine from that for the 807 children assigned to placebo (21.1% vs 24.8%; odds ratio adjusted for center, 0.82; 95% CI, 0.65-1.03; P = .09). The rates of death, motor impairment, behavior problems, poor general health, deafness, and blindness did not differ significantly between the 2 groups. The incidence of cognitive impairment was lower at 5 years than at 18 months and similar in the 2 groups (4.9% vs 5.1%; odds ratio adjusted for center, 0.97; 95% CI, 0.61-1.55; P = .89). Neonatal caffeine therapy was no longer associated with a significantly improved rate of survival without disability in children with very low birth weights who were assessed at 5 years.

    There is evidence that specific psychological treatments are effective in patients with eating disorders. Our goal was to determine by means of a controlled trial whether psychological treatments, previously found to be effective in anorexia nervosa, gave rise to enduring benefits. A 5-year follow-up was conducted on patients who had participated in a previous trial of family therapy for anorexia and bulimia nervosa. Family therapy or individual supportive therapy had been administered to 80 outpatients for 1 year beginning on discharge from hospital after weight restoration. The 80 patients had been subdivided into 4 prognostically homogeneous groups of which 2 turned out to be the most important: patients with early onset and short history of anorexia nervosa, and patients with late-onset anorexia nervosa. At the 5-year follow-up, the efficacy of the outpatient therapies was again assessed by the maintenance of weight, and the categories of general outcome and dimensions of clinical functioning defined by the Morgan-Russell scales. Significant improvements were found in the group of 80 patients as a whole, mainly attributable to the natural outcome of anorexia nervosa, and most evident in the early onset and short history group, as expected. Within 2 of the prognostic groups, significant benefits attributable to previous psychological treatments were still evident, favoring family therapy for patients with early onset and short history of anorexia nervosa and favoring individual supportive therapy for patients with late-onset anorexia nervosa. Much of the improvements found at a 5-year follow-up can be attributed to the natural outcome of the illness. Nevertheless, it was still possible to detect long-term benefits of psychological therapies completed 5 years previously.

    Decreased smell could cause appetite suppression and malnutrition. However, there is a paucity of longitudinal data between olfaction and nutritional status in older adults. We aimed to prospectively examine the relationship between olfactory impairment and overall diet quality (reflecting adherence to dietary guidelines) in a population-based cohort of older adults. We used 5-year follow-up data from 557 adults (aged 60+ years at baseline) whose olfaction was measured using the San Diego Odor Identification Test (SDOIT). Dietary data were collected using a validated semiquantitative food frequency questionnaire. A total diet score (TDS) was calculated for intake of selected food groups and nutrients for each participant as described in the national dietary guidelines. Final scores ranged from 0 to 20; higher scores indicated closer adherence to dietary guidelines. After adjusting for all potential confounders, older adults with moderate/severe olfactory impairment (SDOIT score ≤ 3; lower scores indicate impairment) compared with those with no olfactory impairment had significantly lower adjusted mean (±SE) TDS, 9.09 (0.40) versus 9.94 (0.10), p = 0.04. Women with moderate/severe impaired olfaction (i.e., scored poorly on the odor identification test) compared with those with normal olfaction had significantly lower adjusted mean TDS, 8.87 (0.69) versus 10.31 (0.13), p = 0.04. No associations were observed between olfaction and TDS in men. Olfactory impairment in older women could signal an increased risk of poorer diet quality, defined as adherence to national dietary guidelines. Additional longitudinal studies are needed to confirm or refute the observed link between olfactory loss and overall patterns of food intake in older adults.

    Major depressive disorder (MDD) and smoking are major public health problems and epidemiologically strongly associated. However, the relationship between smoking and depression and whether this is influenced by common confounding factors remain unclear, in part due to limited longitudinal data on covariation. In the Vantaa Depression Study, psychiatric out- and inpatients with DSM-IV MDD and aged 20-59 years at were followed from baseline to 6 months, 18 months, and 5 years. We investigated course of depression, smoking, and comorbid alcohol-use disorders among the 214 patients (79.6% of 269) participating at least three time points; differences between smoking versus nonsmoking patients, and covariation of MDD, smoking, and alcohol-use disorders. Overall, 31.3% of the patients smoked regularly, 41.1% intermittently, and 27.6% never. Smokers were younger, had more alcohol-use disorders and Cluster B and C personality disorder symptoms, a higher frequency of lifetime suicide attempts, higher neuroticism, smaller social networks, and lower perceived social support than never smokers. Smoking and depression had limited longitudinal covariation. Depression, smoking, and alcohol-use disorders all exhibited strong autoregressive tendencies. Among adult psychiatric MDD patients, smoking is strongly associated with substance-use and personality disorders, which may confound research on the impact of smoking. Rather than depression or smoking covarying or predicting each other, depression, smoking, and alcohol-use disorders each have strong autoregressive tendencies. These findings are more consistent with common factors causing their association than either of the conditions strongly predisposing to the other. © 2013 Wiley Periodicals, Inc.

    Full Text Available Introduction: Emergency physicians (EPs are reported to have a higher rate of substance use disorder (SUD than most specialties, although little is known about their prognosis. We examined the outcomes of emergency physician compared to other physicians in the treatment of substance use disorders in Physician Health Programs (PHP. Methods: This study used the dataset from a 5-year, longitudinal, cohort study involving 904 physicians with diagnoses of SUD consecutively admitted to one of 16 state PHPs between 1995 and 2001. We compared 56 EPs to 724 other physicians. Main outcome variables were rates of relapse, successful completion of monitoring, and return to clinical practice. Results: EPs had a higher than expected rate of SUD (odds ratio [OR] 2.7 confidence interval [CI]: 2.1–3.5, p,0.001. Half of each group (49% of EPs and 50% of the others enrolled in a PHP due to alcohol-related problems. Over a third of each group (38% of EPs and 34% of the others enrolled due to opioid use. During monitoring by the PHPs, 13% of EPs had at least one positive drug test compared to 22% of the other physicians; however, this difference was not significant (p¼0.13. At the end of the 5-year follow-up period, 71% of EPs and 64% of other physicians had completed their contracts and were no longer required to be monitored (OR 1.4 [CI: 0.8-2.6], p ¼ 0.31. The study found that the proportion of EPs (84% continuing their medical practice was generally as high as that of other physicians (72% (OR 2.0 [CI: 1.0–4.1], p ¼ 0.06. Conclusion: In the study EPs did very well in the PHPs with an 84% success rate in completion and return to clinical practice at 5 years. Of the 3 outcome variables measured, rates of relapse, successful completion of monitoring, and return to clinical practice, EPs had a high rate of success on all variables compared to the other physician cohort. These data support the conclusion that EM physicians do well following treatment of SUD

    Community-based longitudinal study on stroke is rare in India. It has been predicted that the stroke incidence will be higher in developing countries than developed countries. Hence a five years prospective study was planned to carry out in the rural Bengal, India based on WHO protocol to determine the incidence rate, risk factors, morbidity and mortality profile of stroke. In a two-stage procedure, 20717 subjects out of 20842 people from a cluster of 12 villages was surveyed by house-to-house method and the screened cases were examined by a team of neurologists including post stroke surveillance for one year. Altogether 128 first ever stroke cases were detected over 5 years showing an average annual incidence rate of 123.57 per 100,000 persons [age adjusted incidence rate (AAIR)--262/100,000; based on USA population, 1990] and sex-specific AAIR (274/100,000) among women is slightly higher than men (253/100,000). Age-specific stroke incidence rate showed increasing rate from fourth decade up to seventh decade in both sexes when the rate was maximum. First 30 days mortality recorded was 18% with men suffering twice than women. Follow-up after one year revealed speech improvement in 47%, residual spasticity in 46% and independency in activities daily living in 62% of cases. Age and sex matched case control study has shown that hypertension (OR - 2.79), heart disease (OR - 6.20) and smoking (OR - 3.92) are significant risk factors. This study had indicated a higher age adjusted incidence rate of stroke in India as compared to that of developed country and hypertension, heart disease and smoking are important risk factors.

    The purpose of this article is to describe chiropractic management of a 5-year-old boy with urinary and bowel incontinence. A 5-year-old boy presented with the primary symptoms of a complete lack of bowel and bladder control with prior surgical correction for lumbar meningocele, spinal lipoma, and tethered spinal cord. Examination revealed spinal and pelvic dysfunction. Chiropractic treatment methods included using the Activator adjusting instrument and shortwave diathermy to the lumbar spine and sacrum. A total of 5 treatments were initially provided over a period of 4 weeks. After the initial treatment period, he was able to maintain satisfactory control of his bladder and bowel, day and night, for a period of approximately 6 months. A second course of treatments was initiated approximately 6 months later because of a recurrence of bladder and bowel incontinence. Four additional treatments were provided over a period of 4 weeks. This second course of treatment reestablished satisfactory control of bladder and bowel function. For this patient, chiropractic care was successful in establishing satisfactory bladder and bowel control.

    We achieve a pulsed fiber laser based on injecting a pulsed-seed into a high power fiber ring cavity consisting of two-stage amplifier chain. Through gain control of the fiber amplifier chain and adjustment of a variable optical coupler in the cavity, locking condition is satisfied which produce mode-hopping free, single-longitudinal-mode optical spectrum with 38 dB optical signal to noise ratio. The noise-free lasing RF spectrum has a 7.0 kHz 3 dB linewidth. The nanosecond lasing pulses are jittering-free with 40 W peak power at 1550 nm wavelength.

    A model tunnel (1:30 compared to a standard tunnel section) with a helium-air smoke mixture was used to study the vehicular blockage effect on longitudinal ventilation smoke control. The experimental results showed excellent agreement with full-scale data and confirmed that the critical velocity...... decreases in proportion with the blockage ratio. Nevertheless, it was found that the relative position of the fire source and the relative size of the vehicular blockage can have an opposite effect, as the vehicular blockage influenced the critical and confinement velocity. The method demonstrated...... the ability to provide valuable information on the effect of vehicular blockage on tunnel fire dynamics....

    Prior study children from a DTaP efficacy trial were recruited at ages 5 and 15 years to randomized booster trials addressing immunogenicity and reactogenicity; 475 preschool children received mixed or separate injections of a reduced antigen vaccine (Tdap5, Sanofi Pasteur MSD) and an inactivated polio vaccine, and 230 adolescents received the same or another booster vaccine (Tdap1, SSI, Denmark). Pre-vaccination antibody concentrations against pertussis antigens were significantly higher at 15 than 5 years of age, probably due to natural boosting between the studies. Tdap5 induced comparable anti-PT concentrations at both ages, but antibody responses were significantly higher to filamentous haemagglutinin, pertactin and fimbriae 2/3 in adolescents. As expected, a higher amount of PT (Tdap1, 20μg) induced a stronger anti-PT response than a lower amount (Tdap5, 2.5μg). The frequency of adverse events was low and there were no serious adverse reactions. All local reactions had an early onset and a short duration. A large swelling or redness of more than half of the upper arm circumference was reported in 8/475 5-year-olds and in 6/230 15-year-olds. Children vaccinated with Tdap5 reported more moderate pain in adolescence than at preschool age, whereas itching was only reported in preschool children. Sweden introduced DTaP vaccines in 1996 after a 17-year hiatus with no general pertussis vaccination and pertussis was still endemic at the time of the studies. The frequency of adverse events was nevertheless low in both preschool children and adolescents and antibody responses were adequate. These studies document immunogenicity and reactogenicity in a trial cohort consecutively vaccinated with acellular pertussis vaccines from infancy to adolescence. The adolescent study was registered at ClinicalTrials.gov on 26 March 2009 (NCT00870350). Copyright © 2015 Elsevier Ltd. All rights reserved.

The longitudinal changes in St George’s Respiratory Questionnaire (SGRQ scores were annually evaluated with forced expiratory volume in 1 second (FEV1. The subjects were classified into the rapid decliners, slow decliners, and sustainers based on ∆FEV1/year.Results: The activity component of SGRQ generally deteriorated over time, and its annual decline was the greatest in the rapid decliners (<25th percentile. In contrast, the symptom component improved significantly year by year in the sustainers (>75 percentile, and it did not deteriorate even in the rapid decliners. Of the baseline data, predictors for worsening of the activity component were older age and lower body mass index. Larger reversibility was related to symptom component improvement. Of the follow-up data, ∆FEV1/year was the best predictor for worsening of the components of SGRQ. Continuous smoking was another factor for worsening of the activity component. For the symptom component, a history of exacerbation by admission definition was the determinant of its deterioration, whereas use of beta agonists was related to improvement.Conclusion: The longitudinal changes of quality of life and their determinants are markedly different and independent between its components. The activity component of SGRQ generally deteriorated over years

    Full Text Available Childhood chronic pancreatitis is a rare disorder, which can lead to a chronically debilitating condition. The etiology of recurrent hereditary pancreatitis, which previously was classified as idiopathic, has now been attributed in certain cases to specific genetic mutations including abnormalities in the PRSS gene. We describe here the use of total pancreatectomy and autoislet transplant in a 5-year-old with chronic pancreatitis. This represents the youngest patient undergoing the procedure at our institution. The early successful outcomes for this patient, both of symptom relief and glycemic control are detailed.

    A certain weight gain occurs after obesity surgery compared to the lower weight usually observed between 18 and 24 months postsurgery. The objective of this study was to evaluate weight regain in patients submitted to gastric bypass over a 5-year follow-up period. A longitudinal prospective study was conducted on 782 obese patients of both genders. Only patients with at least 2 years of surgery were included. The percentage of excess body mass index (BMI) loss at 24, 36, 48, and 60 months postsurgery was compared to the measurements obtained at 18 months after surgery. Surgical therapeutic failure was also evaluated. Percent excess BMI loss was significant up to 18 months postsurgery (p < 0.001), with a mean difference in BMI of 1.06 kg/m2 compared to 12 months postsurgery. Percent BMI loss was no longer significant after 24 months, and weight regain became significant within 48 months after surgery (p < 0.01). Among the patients who presented weight regain, a mean 8% increase was observed within 60 months compared to the lowest weight obtained at 18 months after surgery. The percentage of surgical failure was higher in the superobese group at all times studied, reaching 18.8% at 48 months after surgery. Weight regain was observed within 24 months after surgery in approximately 50% of patients. Both weight regain and surgical failure were higher in the superobese group. Studies in regard to metabolic and hormonal mechanisms underlying weight regain might elucidate the causes of this finding.

    We conducted longitudinal analyses examining the associations between intimate partner violence (IPV) attitudes and women's reported IPV in couples (N = 762) using 3 waves of data from a randomized controlled trial in Maharashtra, India. We found that, between Waves 1 and 2, men's and women's acceptance of IPV in the overall population decreased significantly while reports of IPV increased. These changes, we hypothesize, are evidence of an exogenous shock, possibly a high profile rape in Delhi in December 2012, that may have impacted the entire population. Cross-sectional associations between men's attitudes towards IPV and reported IPV were not significant in Wave 1, while positively and significantly associated in Waves 2 and 3. Longitudinal analysis showed that reduction in men's acceptance of IPV between Waves 1 and 2 was associated with a lower likelihood of reported IPV in Wave 3. Women's Wave 1 acceptance of IPV was positively associated with reported IPV in the Wave 1 cross-sectional analysis, while Wave 2 and Wave 3 measures of IPV acceptance were negatively associated with reported IPV in Waves 2 and 3 respectively. Longitudinal analyses of the change in women's attitudes towards IPV from Wave 1 to 2 and reported IPV in Wave 3 were insignificant. However, When women first reported IPV in Waves 2 or 3 they were less likely to report acceptance of IPV in that same wave. Findings suggest that changes in husbands' IPV acceptance is predictive of subsequent IPV, while newly experienced IPV predicts decreased IPV acceptance for women. Wave 2 and Wave 3 results were significant for the control group only, evidence that the intervention affected those associations, potentially changing attitudes more quickly than behavior. We recommend interventions that expose community opposition to IPV as a new social norm, and analysis of how the 2012 Delhi rape case may have affected these norms. Copyright © 2017.

    Long-term results from randomized, controlled trials that compare medical therapy with surgical therapy in patients with type 2 diabetes are limited. We assessed outcomes 5 years after 150 patients who had type 2 diabetes and a body-mass index (BMI; the weight in kilograms divided by the square of the height in meters) of 27 to 43 were randomly assigned to receive intensive medical therapy alone or intensive medical therapy plus Roux-en-Y gastric bypass or sleeve gastrectomy. The primary outcome was a glycated hemoglobin level of 6.0% or less with or without the use of diabetes medications. Of the 150 patients who underwent randomization, 1 patient died during the 5-year follow-up period; 134 of the remaining 149 patients (90%) completed 5 years of follow-up. At baseline, the mean (±SD) age of the 134 patients was 49±8 years, 66% were women, the mean glycated hemoglobin level was 9.2±1.5%, and the mean BMI was 37±3.5. At 5 years, the criterion for the primary end point was met by 2 of 38 patients (5%) who received medical therapy alone, as compared with 14 of 49 patients (29%) who underwent gastric bypass (unadjusted P=0.01, adjusted P=0.03, P=0.08 in the intention-to-treat analysis) and 11 of 47 patients (23%) who underwent sleeve gastrectomy (unadjusted P=0.03, adjusted P=0.07, P=0.17 in the intention-to-treat analysis). Patients who underwent surgical procedures had a greater mean percentage reduction from baseline in glycated hemoglobin level than did patients who received medical therapy alone (2.1% vs. 0.3%, P=0.003). At 5 years, changes from baseline observed in the gastric-bypass and sleeve-gastrectomy groups were superior to the changes seen in the medical-therapy group with respect to body weight (-23%, -19%, and -5% in the gastric-bypass, sleeve-gastrectomy, and medical-therapy groups, respectively), triglyceride level (-40%, -29%, and -8%), high-density lipoprotein cholesterol level (32%, 30%, and 7%), use of insulin (-35%, -34%, and -13%), and

    Full Text Available Background: "Mental disorder" is the most common used term in the modern life and the main reason behind this may be the mechanical way of life or stress and strain among youth. Aim: To find the pattern of mental disorders of hospitalized patients in a medical college hospital from 1 st April 2005 to 31 st March 2010. Settings and Design: A retrospective study conducted among the patients admitted with mental disorders in a medical college hospital from 1 st April 2005 to 31 st March 2010. Materials and Methods: Data collected from the registers maintained in the medical records department. Statistical Analysis: Z test is used for the comparison of proportions. Results: A total of 7908 mental disorder cases reported in the medical college hospital, 5564 (70.36% were males and 2344 (29.64% were females. Most cases occurred in the age group of 30-44 years. Mental disorder was more among females than males in 0-29 years and ≥ 60 years, but in 30-59 years males were more. In each year, mental disorders were reported more in males than females. Of the cases, most of them were mood disorders. Mental and behavioral disorders due to psychoactive substance use were more among males but schizophrenia, delusional disorders, mood disorders, stress-related disorders, mental retardation, and so on were more among females. Conclusion: Mood disorder was the most occurred mental disorder and the next leading mental disorder was mental and behavioral disorders due to psychoactive substance use. Counseling can be helpful for preventing most of the mental disorders. Improve the mental health care facilities will be the solution for controlling the mental disorders.

    2014-07-01

    Full Text Available Background: Thalassemia is a genetic disease having 3-7% carrier rate in Indians. It is transfusion dependent anemia having high risk of iron overloading. A clinical symptom of iron overload becomes detectable in second decade causing progressive liver, heart and endocrine glands damage. There is a need to assess iron overload in thalassemics below 5 years of age to protect them from complications at later age of life. Aims and objectives: Present study was undertaken to estimate serum iron status and evaluate serum transferrin saturation in both homozygous & heterozygous form of thalassemia as an index of iron overload among children of one to five years of age. Materials and Methods: Clinically diagnosed thirty cases of β thalassemia major & thirty cases of β thalassemia minor having severe anemia, hepatospleenomegaly and between 1 year to 5 years of age were included in study group and same age matched healthy controls were included in the study. RBC indices and HbA, HbA2 and HbF were estimated along with serum iron & serum Total Iron Binding Capacity (TIBC and serum transferrin levels. Results: Significant difference was observed in hemoglobin levels between control and both beta thalassemia groups. Mean Corpuscular Volume (MCV and Mean Corpuscular Hemoglobin (MCH values were reduced. Hemoglobin electrophoresis showed the elevated levels of HbF and HbA2 in both beta thalassemia groups. Among serum iron parameters, serum iron, TIBC and transferrin saturation were elevated whereas serum transferrin levels were low in thalassemia major in children below 5 years of age. Conclusion: Although clinical symptoms of iron overload have been absent in thalassemic children below five years of age, biochemical iron overloading has started at much lower age which is of great concern.

Outpatient hysteroscopy facility in a large teaching hospital. One-thousand three-hundred and twenty-one women who underwent hysteroscopic sterilization with Essure device (Conceptus, Inc., Mountain View, CA) between January 2003 and May 2005. Hysteroscopic tubal sterilization using Essure system. Efficacy/effectiveness, failure rate. Satisfactory insertion was accomplished in the first attempt in 1166 women (97.16%). After the second attempt, successful insertion rate rise to 98.6%. (n = 31, 2.6%). Three pregnancies had been reported after 5 years follow up, which implies an overall absolute rate of 0.25%. This represents a Pearl index of 0.05 after 72,000 months of surveillance. All of them occurred in the first year of use of the microinsert. There has been no unintended pregnancy in the next 4 years. Essure has the lowest Pearl index never published being the most effective permanent birth control system to date. Unintended pregnancies tend to occur in the first year after the insertion, and can be avoided encouraging women to accomplish the protocol.

    [Purpose] The purpose of this study was to examine the gross motor skill development of 5-year-old Kindergarten children in Myanmar. [Subjects and Methods] Total 472 healthy Kindergarten children (237 males, 235 females) of 2016-2017 academic year from four schools in urban area and four schools in rural area of Myanmar were recruited. The gross motor skill development of all subjects was assessed with the test of gross motor development second edition (TGMD-2). All subjects performed two trials for each gross motor skill and the performance was video recorded and scored. The assessment procedures were done according to the standardized guidelines of TGMD-2. [Results] The majority of subjects had average level of gross motor skill rank. The significant differences were found on the run and gallop of locomotor skills and the most of object control skills except the catch between males and females. The significant differences were also found between subjects from urban and rural areas. [Conclusion] Gross motor skill development of 5-year-old Kindergarten children in Myanmar had gender-based and region-based differences on both locomotor and object control skills. This study added a valuable information to the establishment of a normative reference of Kindergarten aged children for future studies.

    Panel mediation models and fixed-effects models were used to explore longitudinal relations among parents' reactions to children's displays of negative emotions, children's effortful control (EC), and children's math achievement (N = 291; M age in fall of kindergarten = 5.66 years, SD = .39 year) across kindergarten through second grade. Parents reported their reactions and children's EC. Math achievement was assessed with a standardized achievement test. First-grade EC mediated the relation between parents' reactions at kindergarten and second-grade math achievement, beyond stability in constructs across study years. Panel mediation model results suggested that socialization of EC may be one method of promoting math achievement in early school; however, when all omitted time-invariant covariates of EC and math achievement were controlled, first-grade EC no longer predicted second-grade math achievement. © 2014 The Authors.

    The purpose of the present study was to examine the link between low self-control, motivation, and digital piracy. This study used short-term longitudinal data (i.e., once a week for 4 weeks) from undergraduate students (n = 292) and latent trajectory analysis. The results of this study revealed that the students had significant variability in initial levels and rates of change in digital piracy. The results indicated that whether motivation was treated as a time-invariant or time-varying measure, it along with sex (i.e., being male) had a significant link with the initial levels of digital piracy and that sex and low self-control had links with the rate of change. These results are discussed, and policy implications are made.

    To investigate if application of macrocyclic gadolinium-based contrast agents in volunteers is associated with neuronal deposition detected by magnetic resonance imaging in a 5-year longitudinal survey. Three hundred eighty-seven volunteers who participated in a population-based study were enrolled. Subjects underwent plain T1-weighted brain MRI at baseline and 5 years later with identical sequence parameters. At baseline, 271 participants additionally received intravenous injection of the macrocyclic contrast agent gadobutrol (1.5 mmol/kg). A control group including 116 subjects received no contrast agent. Relative signal intensities of thalamus, pallidum, pons and dentate nucleus were compared at baseline and follow-up. No difference in relative signal intensities was observed between contrast group (thalamus, p = 0.865; pallidum, p = 0.263; pons, p = 0.533; dentate nucleus, p = 0.396) and control group (thalamus, p = 0.683; pallidum; p = 0.970; pons, p = 0.773; dentate nucleus, p = 0.232) at both times. Comparison between both groups revealed no significant differences in relative signal intensities (thalamus, p = 0.413; pallidum, p = 0.653; pons, p = 0.460; dentate nucleus, p = 0.751). The study showed no significant change in globus pallidus-to-thalamus or dentate nucleus-to-pons ratios. Five years after administration of a 1.5-fold dose gadobutrol to normal subjects, signal intensity of thalamus, pallidum, pons and dentate nucleus did not differ from participants who had not received gadobutrol.

    Full Text Available BACKGROUND : Acute respiratory infections are a leading cause of morbidity and mortality in under - five children in developing countries. Hence, the present study was undertaken to study the various risk factors, clinical profile and outcome of acute lower respiratory tract infections (ALRI in children aged 2 month to 5 years. OBJECTIVE : clinical features, laborato ry assessment and morbidity and mortality pattern associated with acute lower respiratory tract infections in children aged 2 months to 5 years. METHODS: 100 ALRI cases fulfilling WHO criteria for pneumonia, in the age group of 2 month to 5 years were evaluated for clinical profile as per a predesigned proforma in a rural medical college. RESULTS : Of cases 61% were infants and remaining 39%12 - 60 months age group, males outnumbered females with sex ratio of 1.3;1. Elevated total leukocyte counts for age were observed in only 22% of cases, of these 3% were having pneumonia, 9% severe pneumonia and 10% very severe pneumonia. Significant association was found between leukocytosis and ALRI severity (p= 0.0001 Positive blood culture was obtained in 8% of cases and was significantly associated with ALRI severity (p=. 0.027. Among the ALRI cases, 84% required oxygen supplementation at any time during the hospital stay and 8% required mechanical ventilation. The mortality rate was 1%; with 99% of cases recovering and getting discharged uneventfully. CONCLUSION : Among the clinical variables, the signs and symptoms of ALRI as per the WHO ARI Control Programme were found in almost all cases. Regarding the laboratory profile, leukocytosis and blood culture positivity w ere observed in a small percentage, but significant association with ALRI severity was observed for both. Thus, clinical signs, and not invasive blood tests are a better diagnostic tools, though the latter may provide additional therapeutic and prognostic information in severe disease

    Based on the Theory of Planned Behaviour (TPB), the purpose of this investigation was to examine the directionality of the association among condom use, intention, attitudes, subjective norms and perceived behavioural control. The present study investigated the nature of these relationships using a longitudinal cross-lagged design applied to data from a cohort of 958 randomly selected Italian adults. Using structural equation modelling, two cross-lagged panel analyses revealed reciprocal relationships between intention and attitudes and between intention and condom use. Contrary to expectations, baseline subjective norms and perceived behavioural control did not predict subsequent intention to use condom when controlled for the autoregressive effect of intention at T1 on the same variable at T2. Also, perceived behavioural control at T1 did not influence condom use at T2 after controlling for the effect of baseline intention. The possibility of reciprocity was also tested for all relations and significant results were found. The moderation effect of perceived behavioural control on the relationship between intention and condom use was not significant. The differences in age, gender and partnership status were taken into account in the analyses.

    Full Text Available We aim to assess the longitudinal association between baseline estimated cerebrospinal fluid pressure (CSFP and 5-year incident primary open angle glaucoma (POAG in a population-based sample of Bai Chinese living in rural China.Among the 2133 Bai Chinese aged 50 years or older who had participated in the baseline examination of the Yunnan Minority Eye Study, 1520 (71.3% attended the follow-up examination after five years and 1485 were at risk of developing POAG. Participants underwent comprehensive ophthalmic examinations at both baseline and follow-up surveys. CSFP in mmHg was estimated as 0.55 × body mass index (kg/m2 + 0.16 × diastolic blood pressure (mmHg-0.18 × age (years-1.91. Glaucoma was defined using the International Society of Geographical and Epidemiological Ophthalmology Classification criteria. Multivariate logistic regression models were established to determine the association between baseline CSFP and incident POAG.After a mean follow-up time of 5 years, 19 new cases of POAG were detected, with an incidence rate of 1.3% (95% confidence interval, 0.7-1.9%. In multivariate logistic regression analysis, after adjusting for age, gender, education, intraocular pressure, central corneal thickness, hypertension and diabetes, no significant associations, nor any trends, were evident between baseline estimated CSFP and incident POAG. The association between estimated CSFP per mmHg increase in baseline and 5-year incidence of POAG was also non-significant, with adjusted relative risk of 0.96 (P = 0.11 in multivariate analysis.This longitudinal cohort study does not support previously observed cross-sectional association between estimated CSFP and POAG in population-based studies.

    To assess the risk factors associated with diarrhea among children below 5-years-old in Mukalla, Yemen, and compare with other studies.   We conducted a case-control study on 200 children (100 cases and 100 controls) who attended the Maternity and Child Hospital, outpatient-clinics, and the Primary Health Care Centers in Al-Mukalla, Hadhramout, Yemen between February and April 2013.   We found that the significant risk factors associated with diarrhea were crowded housing (odds ratio [OR] 2.02; p=0.02; confidence interval [CI] 1.03-4.01), incomplete vaccination of the child (OR=2.02; p=0.027; CI: 1.08-3.8), and recurrent diarrheal illness during the last 3 months (OR=6.61; p=0.001; CI: 3.41-12.90).   Diarrheal diseases are strongly associated with incomplete vaccination, recurrent diarrheal disease, and crowded housing.

    Full Text Available During adolescence, prefrontal cortex regions, important in cognitive control, undergo maturation to adapt to changing environmental demands. Ways through which social-ecological factors contribute to adolescent neural cognitive control have not been thoroughly examined. We hypothesize that household chaos is a context that may modulate the associations among parental control, adolescent neural cognitive control, and developmental changes in social competence. The sample involved 167 adolescents (ages 13–14 at Time 1, 53% male. Parental control and household chaos were measured using adolescents’ questionnaire data, and cognitive control was assessed via behavioral performance and brain imaging at Time 1. Adolescent social competence was reported by adolescents at Time 1 and at Time 2 (one year later. Structural equation modeling analyses indicated that higher parental control predicted better neural cognitive control only among adolescents living in low-chaos households. The association between poor neural cognitive control at Time 1 and social competence at Time 2 (after controlling for social competence at Time 1 was significant only among adolescents living in high-chaos households. Household chaos may undermine the positive association of parental control with adolescent neural cognitive control and exacerbate the detrimental association of poor neural cognitive control with disrupted social competence development.

    The Advanced Land Imager (ALI) was developed as a prototype sensor for follow on missions to Landsat-7. It was launched in November 2000 on the Earth Observing One (EO-1) satellite as a nominal one-year technology demonstration mission. As of this writing, the sensor has continued to operate in excess of 5 years. Six of the ALl's nine multi-spectral (MS) bands and the panchromatic band have similar spectral coverage as those on the Landsat-7 ETM+. In addition to on-board lamps, which have been significantly more stable than the lamps on ETM+, the ALI has a solar diffuser and has imaged the moon monthly since launch. This combined calibration dataset allows understanding of the radiometric stability of the ALI system, its calibrators and some differentiation of the sources of the changes with time. The solar dataset is limited as the mechanism controlling the aperture to the solar diffuser failed approximately 18 months after launch. Results over 5 years indicate that: the shortest wavelength band (443 nm) has degraded in response about 2%; the 482 nm and 565 nm bands decreased in response about 1%; the 660 nm, 790 nm and 868 nm bands each degraded about 5%; the 1250 nm and 1650 nm bands did not change significantly and the 2215 nm band increased in response about 2%.

  12. Shockwave-Based Automated Vehicle Longitudinal Control Algorithm for Nonrecurrent Congestion Mitigation

    2017-01-01

    Full Text Available A shockwave-based speed harmonization algorithm for the longitudinal movement of automated vehicles is presented in this paper. In the advent of Connected/Automated Vehicle (C/AV environment, the proposed algorithm can be applied to capture instantaneous shockwaves constructed from vehicular speed profiles shared by individual equipped vehicles. With a continuous wavelet transform (CWT method, the algorithm detects abnormal speed drops in real-time and optimizes speed to prevent the shockwave propagating to the upstream traffic. A traffic simulation model is calibrated to evaluate the applicability and efficiency of the proposed algorithm. Based on 100% C/AV market penetration, the simulation results show that the CWT-based algorithm accurately detects abnormal speed drops. With the improved accuracy of abnormal speed drop detection, the simulation results also demonstrate that the congestion can be mitigated by reducing travel time and delay up to approximately 9% and 18%, respectively. It is also found that the shockwave caused by nonrecurrent congestion is quickly dissipated even with low market penetration.

    Although the development of spoken language is dependent on the emergence of cognitive, language, and speech motor skills, knowledge about how these domains interact during the early stages of communication development is currently limited. This exploratory investigation examines the strength of associations between longitudinal changes in articulatory kinematics and development of skills in multiple domains thought to support early communication development. Twenty-four infants were investigated every three months between the ages of 9 and 21 months. Movements of the upper lip, lower lip, and jaw were transduced using a three-dimensional motion capture system to obtain age-related changes in movement speed and range of movement. Standardized measures of cognition and language from the Battelle Developmental Inventory, 2nd edition and the MacArthur-Bates Child Development Inventory were also collected. Significant associations were identified between orofacial kinematic and the standardized measures of language and cognitive skills, even when age served as covariate. These findings provide preliminary evidence of interactions between cognition, language, and speech motor skills during early communication development. Further work is needed to identify and quantify causal relations among these co-emerging skills. PMID:21035125

    Evidence supporting the association between skipping breakfast and children's body mass index (BMI) has been widely reported, and some consideration has been given to children aged 2-5 years. However, no evidence has considered an association between children skipping breakfast and mother's BMI. This study therefore investigated associations between skipping breakfast, child's BMI and mother's BMI in a large cohort of Australian children. Data were drawn from wave 2 (2-3 years, n=4601) and wave 3 (4-5 years, n=4381) of the Longitudinal Study of Australian Children. The primary outcome was skipping breakfast. Child's and mother's BMI was assessed by trained professionals. Girls at 4-5 years were significantly more likely to skip breakfast compared with boys (56.9% versus 43.1%; P=0.031). In cross-sectional data analysis, obese boys at 2-3 years (odds ratio (OR) 2.38; P=0.039) and at 4-5 years (OR 2.32; P=0.046), and also obese girls at 4-5 years (OR 2.26; P=0.018), were more likely to skip breakfast. Skipping breakfast was positively associated with boys at 2-3 years (OR 2.04; P=0.042) whose mothers were overweight and with girls at 4-5 years (OR 2.60; P=0.001) whose mothers were obese. In longitudinal cross-lagged analysis, boys at 2-3 years whose mothers were obese were more likely to skip breakfast 2 years later at age 4-5 years (OR 2.36; P=0.045). Skipping breakfast was associated with higher BMI in children and mothers. Future interventions should target obese mothers to promote breakfast intake among children. The interventions may involve changes to dietary and lifestyle habits and provision of education on the benefits of breakfast intake.

    Full Text Available Abstract Background The sole focus of models of insight on bio-medical perspectives to the complete exclusion of local, non-medical and cultural constructs mandates review. This study attempted to investigate the impact of insight, psychopathology, explanatory models of illness on outcome of first episode schizophrenia. Method Patients diagnosed to have DSM IV schizophrenia (n = 131 were assessed prospectively for insight, psychopathology, explanatory models of illness at baseline, 6, 12 and 60 months using standard instruments. Multiple linear and logistic regression and generalized estimating equations (GEE were employed to assess predictors of outcome. Results We could follow up 95 (72.5% patients. Sixty-five of these patients (68.4% achieved remission. There was a negative relationship between psychosis rating and insight scores. Urban residence, fluctuating course of the initial illness, and improvement in global functioning at 6 months and lower psychosis rating at 12 months were significantly related to remission at 5 years. Insight scores, number of non-medical explanatory models and individual explanatory models held during the later course of the illness were significantly associated with outcome. Analysis of longitudinal data using GEE showed that women, rural residence, insight scores and number of non-medical explanatory models of illness held were significantly associated with BPRS scores during the study period. Conclusions Insight, the disease model and the number of non-medical model positively correlated with improvement in psychosis arguing for a complex interaction between the culture, context and illness variables. These finding argue that insight and explanatory models are secondary to psychopathology, course and outcome of the illness. The awareness of mental illness is a narrative act in which people make personal sense of the many challenges they face. The course and outcome of the illness, cultural context

    Rates of gambling and gambling-related harm fluctuate over time, influenced by availability, adaptation and demographic change, among other things. Assessing change is compromised by methodological variation. The main aim of this paper is to assess change in gambling participation and problems in adult Victorians over a 5-year period. Data are from the Victorian Gambling Study (VGS) 2008-2012 (n = 15,000) and the 2003 Victorian Longitudinal Attitudes Survey (n = 8479). An additional aim was to determine the impact of methodological differences on prevalence estimates. Despite gambling availability increasing and more activities being included participation rates declined substantially. Decreases occurred across almost all demographic groups and gambling activities. When adjustments were made for methodological differences there were no significant changes in problem, moderate risk and low risk gambling. Males and people with lower education had higher rates in both surveys. In the latter survey, two groups that experienced large participation reductions, namely young adults and metropolitan residents, emerged as additional groups with higher rates of problem and moderate-risk gambling. Further research is required to discover why overall rates of harm may have plateaued when participation continues to fall and why some groups with reduced participation experience increased harm. The findings suggest that availability and total consumption models are over-simplistic. They further suggest that to be effective prevention programmes will need to extend beyond gambling availability to include interventions directed towards individuals at risk and wider environmental determinants of vulnerability and harm. Additionally this study found that restricting administration of the problem gambling measure to subsets of gamblers generate significantly lower prevalence estimates, implying that many previous surveys under-portray gambling-related harm and that without appropriate

    To describe longitudinal changes in leisure-time sedentary behavior among girls, during early to mid-adolescence. A 2.5-year prospective cohort study, comprising 5 data collections, 6 months apart, between 2000 and 2002. Girls aged 12-15 years (n = 200) from 8 high schools located in Sydney, Australia, self-reported the usual time spent each week in a comprehensive range of sedentary behaviors. Retention rate for the study was 82%. Girls aged 12.8 years spent approximately 45% of their discretionary time in sedentary behavior, which increased to 63% at age 14.9 years. Watching TV, videos, and playing video games (small screen recreation; SSR) was the most popular sedentary pastime, accounting for 33% of time spent in sedentariness, followed by homework and reading (25%). Sedentary behavior increased 1.4 and 3.3 hours on week and weekend days, respectively. On weekdays, increased time was spent on hobbies (27 min/day) and on weekend days, increased time was spent sitting around talking with friends (60 min/day), computer use (37 min/day), and television viewing (34 min/day). Among girls, the transition between early and mid-adolescence was accompanied by a significant increase in leisure-time sedentary behavior. Interventions to reduce sedentariness among adolescent girls are best to focus on weekend behaviors. Studies seeking to examine the association between inactivity and the development of chronic health problems need to examine a diverse range of activities that comprehensively measure sedentariness. This information will provide a better understanding of inactivity patterns among adolescent girls.

    OBJECTIVES To examine the relationship between anxiety and functional decline. DESIGN A 5-year longitudinal cohort study of well-functioning adults. SETTING The Health, Aging and Body Composition (Health ABC) Study. PARTICIPANTS Two thousand nine hundred forty adults aged 70 to 79 (48% male, 41% black), initially free of self-reported mobility difficulty. MEASUREMENTS In 1997/98, presence of three anxiety symptoms (feeling fearful, tense or keyed up, or shaky or nervous) from the Hopkins Symptom Checklist were ascertained. Physical function was examined over 5 years using the Health ABC performance battery (continuous range 0–4) consisting of chair stands, usual and narrow course gait speed, and difficulty with standing balance and self-reported mobility, defined as difficulty walking one-quarter of a mile or difficulty climbing 10 steps. RESULTS Participants with anxiety symptoms had similar baseline physical performance scores. After adjustment for potential confounders, subjects with anxiety symptoms had similar declines in physical performance over 5 years as participants without anxiety symptoms. Adults with anxiety symptoms were more likely to report incident mobility difficulty, with a hazard ratio of 1.4 (95% confidence interval =1.3–1.6), compared with adults without anxiety symptoms. These results persisted after adjustment for depressive symptoms, demographics, comorbidity, and use of antianxiety, depressant, and sedative hypnotic medications. CONCLUSION Anxiety symptoms are not associated with declines in objectively measured physical performance over 5 years but are associated with declines in self-reported functioning. Future studies are needed to determine why anxiety has a differential effect on performance-based and self-reported measures of functioning. PMID:17302665

MÉTODO: Quatro mil duzentos e trinta e uma crianças nascidas no ano de 2004, em Pelotas, RS, foram incluídas em um estudo longitudinal. Em visitas domiciliares realizadas aos 12, 24 e 48 meses, as mães responderam a um questionário com questões sociodemográficas, características dos hábitos miccionais e intestinais das crianças, com atenção ao treinamento esfincteriano. RESULTADOS: Aos 48 meses, a maioria das crianças estava sem fraldas durante o dia (98,5% e à noite (83%, sem diferença entre os sexos. A idade média de início de treinamento esfincteriano foi 22 meses, com início mais precoce nas meninas. A duração média do treinamento foi de 3,2 meses, sem diferença entre os sexos. Crianças com atraso de desenvolvimento apresentaram controle esfincteriano mais tardio, havendo relação direta entre a intensidade do desvio da normalidade e a idade da retirada de fraldas. A orientação médica foi fornecida a 15,9% das mães. O treinamento iniciado antes dos 24 meses esteve relacionado com uma maior idade de controle esfincteriano e maior duração do treinamento. Crianças prematuras ou com baixo peso não apresentaram diferença significativa no tempo de treinamento e idade de aquisição do controle esfincteriano. CONCLUSÕES: Até os quatro anos de idade, a maioria das crianças, inclusive prematuros e de baixo peso ao nascer, obtém controle esfincteriano independentemente de fatores externos e do sexo. O início do treinamento (antes dos 24 meses não antecipou o controle esfincteriano, apenas prolongou o tempo de treinamento.OBJECTIVES: To analyze sphincter control acquisition in a birth cohort.

  1. Participation in mass gatherings can benefit well-being: longitudinal and control data from a North Indian Hindu pilgrimage event.

    Full Text Available How does participation in a long-duration mass gathering (such as a pilgrimage event impact well-being? There are good reasons to believe such collective events pose risks to health. There are risks associated with communicable diseases. Moreover, the physical conditions at such events (noise, crowding, harsh conditions are often detrimental to well-being. Yet, at the same time, social psychological research suggests participation in group-related activities can impact well-being positively, and we therefore investigated if participating in a long-duration mass gathering can actually bring such benefits. In our research we studied one of the world's largest collective events - a demanding month-long Hindu religious festival in North India. Participants (comprising 416 pilgrims who attended the gathering for the whole month of its duration, and 127 controls who did not completed measures of self-assessed well-being and symptoms of ill-health at two time points. The first was a month before the gathering commenced, the second was a month after it finished. We found that those participating in this collective event reported a longitudinal increase in well-being relative to those who did not participate. Our data therefore imply we should reconceptualise how mass gatherings impact individuals. Although such gatherings can entail significant health risks, the benefits for well-being also need recognition. Indeed, an exclusive focus on risk is misleading and limits our understanding of why such events may be so attractive. More importantly, as our research is longitudinal and includes a control group, our work adds robust evidence to the social psychological literature concerning the relationship between participation in social group activities and well-being.

    This study's aims are to examine the effects of aromatherapy massage on women's stress and immune function during pregnancy. This longitudinal, prospective, randomized controlled trial recruited 52 healthy pregnant women from a prenatal clinic in Taipei using convenience sampling. The participants were randomly assigned to the intervention (n = 24) or control (n = 28) group using Clinstat block randomization. The intervention group received 70 min of aromatherapy massage with 2% lavender essential oil every other week (10 times in total) for 20 weeks; the control group received only routine prenatal care. In both groups, participants' salivary cortisol and immunoglobulin A (IgA) levels were collected before and after the intervention group received aromatherapy massage (every month from 16 to 36 weeks gestation) and were analyzed using enzyme-linked immunosorbent assay. The pregnant women in the intervention group had lower salivary cortisol (p aromatherapy massage than those in the control group, which did not receive massage treatment. Comparing the long-term effects of aromatherapy massage on salivary IgA levels between groups at different times, the study found that the pretest salivary IgA levels at 32 (p = 0.002) and 36 (p aromatherapy massage could significantly decrease stress and enhance immune function in pregnant women. The findings can guide clinicians or midwives in providing aromatherapy massage to women throughout the pregnancy.

    The optimization of malaria control strategies is complicated by constraints posed by local health systems, infrastructure, limited resources, and the complex interactions between infection, disease, and treatment. The purpose of this paper is to describe the protocol of a randomized factorial study designed to address this research gap. This project will evaluate two malaria control interventions in Mvomero District, Tanzania: (1) a disease management strategy involving early detection and treatment by community health workers using rapid diagnostic technology; and (2) vector control through community-supported larviciding. Six study villages were assigned to each of four groups (control, early detection and treatment, larviciding, and early detection and treatment plus larviciding). The primary endpoint of interest was change in malaria infection prevalence across the intervention groups measured during annual longitudinal cross-sectional surveys. Recurring entomological surveying, household surveying, and focus group discussions will provide additional valuable insights. At baseline, 962 households across all 24 villages participated in a household survey; 2,884 members from 720 of these households participated in subsequent malariometric surveying. The study design will allow us to estimate the effect sizes of different intervention mixtures. Careful documentation of our study protocol may also serve other researchers designing field-based intervention trials.

    The intent of this analysis was to examine the longitudinal effects of risk and protective factors on quality of life (QOL) in caregivers of minority children with asthma. Caregivers (n = 300) reported on demographics, child asthma characteristics, daily asthma caregiving stress, general life stress, social support, and QOL. Latent growth curve modeling examined changes in QOL across 12 months as a function of stress, asthma control, and social support. Caregivers were primarily the biological mother (92%), single (71%), unemployed (55%), and living in poverty. Children were African American (96%), Medicaid eligible (92%), and had poorly controlled asthma (93%). Lower QOL was associated with higher life stress, greater asthma caregiving stress, and lower asthma control over time. Findings underscore the importance of assessing objective and subjective measures of asthma burden and daily life stress in clinical encounters with urban, low-income caregivers of children with poorly controlled asthma.

    During the early years, parents have a major influence on children’s diets and developing food choices. We investigated parenting styles as predictors of 2–5-year-old children’s diets and whether general nutrition knowledge (GNK) mediated these influences. Cross-sectional research. Questionnaires measured demographic and lifestyle variables, family environment, parenting styles and feeding practices, child diet and GNK. Regression models tested GNK as a mediator of relationships between parenting variables and child diet (fruit/vegetable and non-core food consumption), controlling for confounders and family environment. Questionnaires were completed by main caregivers at home. Parents of children aged 2–5 years (n 269). Higher child fruit/vegetable consumption was associated with lower overreactive parenting and restriction, higher authoritative parenting and dining together as a family; with lax parenting approaching statistical significance (P50?083) and 19% of variance explained by the model. GNK was not a significant predictor. Conversely, non-core food consumption was associated with higher over-reactive and lax parenting as well as child age, increased takeaway food consumption and higher television viewing; GNK had a small effect (P = 0.043) and 28% of variance was explained by the model. GNK was a significant mediator only for authoritative parenting on non-core food (effect = -0.005). These findings highlight that young children’s diets may be improved by interventions targeting a range of positive and supportive parenting practices in conjunction with nutrition knowledge education for parents of young children. Further insights will come from closer attention to the nature and role of restrictive feeding practices v. laxness and longitudinal research.

    Psychosocial work factors can affect depressive moods, but research is inconclusive if flexibility to self-determine working hours (work-time control, WTC) is associated with depressive symptoms over time. We investigated if either sub-dimension of WTC, control over daily hours and control over time off, was related to depressive symptoms over time and examined causal, reversed-causal, and reciprocal pathways. The study was based on four waves of the Swedish Longitudinal Occupational Survey of Health which is a follow-up of representative samples of the Swedish working population. WTC was measured using a 5-item index. Depressive symptoms were assessed with a brief subscale of the Symptom Checklist. Latent growth curve models and cross-lagged panel models were tested. Best fit was found for a model with correlated intercepts (control over daily hours) and both correlated intercepts and slopes (control over time off) between WTC and depressive symptoms, with stronger associations for control over time off. Causal models estimating impacts from WTC to subsequent depressive symptoms were best fitting, with a standardised coefficient between -0.023 and -0.048. Results were mainly based on self-report data and mean age in the study sample was relatively high. Higher WTC was related to fewer depressive symptoms over time albeit small effects. Giving workers control over working hours - especially over taking breaks and vacation - may improve working conditions and buffer against developing depression, potentially by enabling workers to recover more easily and promoting work-life balance.

    Low-income women may be especially vulnerable to job loss after a breast cancer diagnosis. The identification of early risk factors for not returning to work in the long term could inform interventions to help survivors avoid this outcome. A consecutive sample of low-income, employed, underinsured/uninsured women treated for stage 0-III breast cancer was surveyed 6, 18, 36, and 60 months after diagnosis. Participants were classified according to the survey in which they first reported return to work. If they were not working in every survey they were classified as not returning to work. Correlates of not returning to work were identified. Of 274 participants, 36 % returned to work by 6 months, an additional 21 % by 18, 10 % by 36, and 5 % by 60 months. 27 % never returned to work. Of those not working at 6 months, 43 % never returned. Independent predictors of never returning to work included lowest annual income (working during chemotherapy for breast cancer are at risk of not returning to work months and years following treatment. These findings may have clinical and policy implications. Conversely, radiation therapy, axillary node dissection, age, and job type do not appear to be associated with return to work. Clinicians should discuss work-related concerns with patients and facilitate early return to work when desired by the patient. Additional research is needed to develop interventions to optimize return to work.

    The main purpose of this study was to identify the longitudinal association between specific parenting styles (authoritarian, authoritative, permissive, and neglectful) and adolescent disordered eating behaviors. The current study uses longitudinal data from a 5-year study to examine the associations between parenting style and disordered eating behaviors among adolescents. Data from adolescents (n = 2516) participating in Project EAT (Eating Among Teens), a population-based study from 31 Minnesota schools, were used in the analysis. Time 1 data were collected using in-class assessments of adolescents from Minneapolis/St. Paul schools, and Time 2 data were collected using mailed surveys 5 years later. General Linear Models were used to predict adolescent-reported disordered eating behaviors at Time 2 from adolescent-reported parenting style at Time 1. Adolescent boys and girls who had authoritarian mothers at Time 1 had a higher probability of extreme weight control behaviors 5 years later compared to adolescents with authoritative, permissive, or neglectful mothers. Adolescent girls with authoritarian mothers at Time 1 had a higher probability of engaging in binge-eating behaviors at Time 2 compared to adolescent girls with authoritative or permissive mothers. There were no significant associations between paternal parenting style and adolescent disordered eating behaviors. Although authoritarian parenting style served as a possible risk factor for disordered eating behaviors in adolescents, the findings were not conclusive. Future studies should investigate further the association between parenting style and weight control behaviors in adolescents.

    A high burden of pain, symptoms and other multidimensional problems persist alongside HIV treatment. WHO policy indicates palliative care as essential throughout the disease course. This study aimed to determine whether palliative care delivered from within an existing HIV outpatient setting improves control of pain and symptoms compared to standard care. A prospective, longitudinal controlled design compared patient outcomes at an outpatient facility that introduced palliative care training to clinicians and stocked essential palliative care drugs, to outcomes of a cohort of patients at a similar HIV care facility with no palliative care, in Tanzania. Inclusion criteria were clinically significant pain or symptoms. Patients were followed from baseline fortnightly until week 10 using validated self-report outcome measures. For the primary pain outcome, the required sample size of 120 patients was recruited. Odds of reporting pain reduced significantly more at intervention site (OR=0.60, 95% CI 0.50-0.72) than at control (OR=0.85, 95% CI 0.80-0.90), p=0.001. For secondary outcomes, longitudinal analysis revealed significant difference in slope between intervention and control, respectively: Medical Outcomes Study-HIV (MOS-HIV) physical score 1.46 vs. 0.54, p=0.002; MOS-HIV mental health 1.13 vs. 0.26, p=0.006; and POS total score 0.84 vs. 0.18, p=0.001. Neither baseline CD4 nor antiretroviral therapy (ART) use was associated with outcome scores. These data are the first to report outcomes evaluating integrated HIV outpatient palliative care in the presence of ART. The data offer substantive evidence to underpin the existing WHO clinical guidance that states an essential role for palliative care alongside HIV treatment, regardless of prognosis.

    Objective This population-based study examined mothers’ weight-related concerns and behaviors (weight status, weight dissatisfaction, dieting, and encouraging child to diet) at baseline, as assessed by both mothers and adolescents, and associations with adolescents’ body dissatisfaction and weight control practices 5 years later. Methods Adolescents and their mothers (n = 443 pairs) were surveyed in 1998–1999; adolescents were resurveyed in 2003–2004. Results Baseline maternal report of higher levels of her weight-related concerns/behaviors was associated with greater body dissatisfaction in girls 5 years later, controlling for adolescent weight status and other covariates. Baseline maternal report of weight-related concerns/behaviors was also associated with greater prevalence of trying to lose weight in both boys and girls 5 years later. Baseline adolescent report of higher maternal weight-related concerns/behaviors was associated with a higher prevalence of trying to lose weight 5 years later in girls. Conclusions These findings highlight the importance of mothers’ weight-related concerns and behaviors for adolescents’ weight-related outcomes.

    Research in older adolescents suggests insufficient sleep may increase substance use initiation risk. This study tested whether sleep duration and dysregulation of sleep-wake patterns in late-elementary school youth were prospectively associated with cigarette and alcohol use initiation and how sleep-related changes in inhibitory control mediate these relationships. Average sleep duration at 4th grade predicted 6th grade cigarette but not alcohol use, however indirect effects were identified through 5th grade inhibitory control to both cigarette and alcohol use. Indirect effects were also identified through inhibitory control for relationships between 4th grade weekend bed-time delay and 6th grade cigarette or alcohol use, and for relationships between 4th grade weekend wake-time delay and 6th grade cigarette or alcohol use. Reductions in nightly sleep increased risk of cigarette use. Findings suggest a pathway linking both reduced sleep duration and greater weekend shifting of sleep patterns to future substance use through sleep-related inhibitory control deficits.

    Selective mutism (SM) has been defined as an anxiety disorder in the diagnostic and statistical manual of mental disorders (DSM-5). Cognitive behavioral therapy (CBT) is the recommended approach for SM, but prospective long-term outcome studies are lacking. Reports from the children themselves, and the use of more global quality of life measures, are also missing in the literature. We have developed a school-based CBT intervention previously found to increase speech in a pilot efficacy study and a randomized controlled treatment study. Continued progress was found in our 1-year follow-up studies, where older age and more severe SM had a significant negative effect upon outcome. In the present study, we provide 5-year outcome data for 30 of these 32 children with SM who completed the same CBT for mean 21 weeks (sd 5, range 8-24) at mean age 6 years (10 boys). Mean age at the 5-year follow-up was 11 years (range 8-14). Outcome measures were diagnostic status, the teacher- and parent-rated selective mutism questionnaires, and child rated quality of life and speaking behavior. At the 5-year follow-up, 21 children were in full remission, five were in partial remission and four fulfilled diagnostic criteria for SM. Seven children (23%) fulfilled criteria for social phobia, and separation anxiety disorder, specific phobia and/or enuresis nocturna were found in a total of five children (17%). Older age and severity at baseline and familial SM were significant negative predictors of outcome. Treatment gains were maintained on the teacher- and parent questionnaires. The children rated their overall quality of life as good. Although most of them talked outside of home, 50% still experienced it as somewhat challenging. These results point to the long-term effectiveness of CBT for SM, but also highlight the need to develop more effective interventions for the subset of children with persistent symptoms.Clinical trials registration NCT01002196.

    We evaluated Legacy for Children, a public health strategy to improve child health and development among low-income families. Mothers were recruited prenatally or at the birth of a child to participate in Legacy parenting groups for 3 to 5 years. A set of 2 randomized trials in Miami, Florida, and Los Angeles, California, between 2001 and 2009 assessed 574 mother-child pairs when the children were 6, 12, 24, 36, 48, and 60 months old. Intent-to-treat analyses from 12 to 60 months compared groups on child behavioral and socioemotional outcomes. Children of mothers in the intervention group were at lower risk for behavioral concerns at 24 months and socioemotional problems at 48 months in Miami, and lower risk for hyperactive behavior at 60 months in Los Angeles. Longitudinal analyses indicated that children of intervention mothers in Miami were at lower risk for behavior problems from 24 to 60 months of age. Randomized controlled trials documented effectiveness of the Legacy model over time while allowing for implementation adaptations by 2 different sites. Broadly disseminable, parent-focused prevention models such as Legacy have potential for public health impact. These investments in prevention might reduce the need for later intervention strategies.

    In a multicentre randomised trial (German Research Association, grants DFG WA 831/2-1 to 2-6, WO 677/2-1.1 to 2-2.1.; controlled-trials.com ISRCTN97265367), patients with complete molar loss in one jaw received either a partial removable dental prosthesis (PRDP) with precision attachments or treatment according to the SDA concept aiming at pre-molar occlusion. The objective of this current analysis was to evaluate the influence of different treatments on periodontal health. Linear mixed regression models were fitted to quantify the differences between the treatment groups. The assessment at 5 years encompassed 59 patients (PRDP group) and 46 patients (SDA group). For the distal measuring sites of the posterior-most teeth of the study jaw, significant differences were found for the plaque index according to Silness and Löe, vertical clinical attachment loss (CAL-V), probing pocket depth (PPD) and bleeding on probing. These differences were small and showed a slightly more unfavourable course in the PRDP group. With CAL-V and PPD, significant differences were also found for the study jaw as a whole. For CAL-V, the estimated group differences over 5 years amounted to 0.27 mm (95% CI 0.05; 0.48; P = 0.016) for the study jaw and 0.25 mm (95% CI 0.05; 0.45; P = 0.014) for the distal sites of the posterior-most teeth. The respective values for PPD were 0.22 mm (95% CI 0.03; 0.41; P = 0.023) and 0.32 mm (95% CI 0.13; 0.5; P = 0.001). It can be concluded that even in a well-maintained.patient group statistically significant although minor detrimental effects of PRDPs on periodontal health are measurable. © 2014 John Wiley & Sons Ltd.

    Childhood behavioral problems can predict future psychiatric disorders. Temperament development is important for a healthy personality in adulthood. This study investigated whether breastfeeding is associated with the occurrence of behavioral problems and the temperament development in preschool children. A total of 737 children (399 boys and 338 girls) aged 4-5 years in Zibo City were recruited by stratified random cluster sampling. They were born at term with a birth weight of >/= 2.5 kg. The feeding patterns and the breastfeeding duration in infancy were collected. Behavioral and temperament developments were investigated by the Achenbach Child Behavior Checklist (CBCL), temperament questionnaire for 3-7-year-old children and a self-designed inventory questionnaire. The association of feeding patterns and the breastfeeding duration with behavioral problem occurrence and the temperament development in children were analyzed by a multivariate non-conditional logistic regression analysis and a multivariate stepwise regression analysis. After controlling for confounding variables, such as family income and parental education levels, it was found that a breastfeeding duration of >/= 9 months was a protective factor against behavioral problem occurrence in boys (OR=0.184). In girls, a breastfeeding duration of >/= 9 months was also a protective factor against behavioral problem occurrence (OR=0.165), while a mixed feeding with more breast milk and less formula milk was a risk factor (OR=2.203). The factors influencing temperament development consisted of exclusive formula feeding and the duration of breastfeeding (lasting for 4-6 months or 7-9 months) as well as a mixed feeding (with more formula milk and less breast milk, more breast milk and less formula milk, or equal amount of both). The fewer amounts and the shorter duration of breastfeeding are risk factors for behavioral problems occurrence in children aged 4-5 years. Children's temperament development is

    Spirituality is favorably related to depression, quality of life, hospitalizations, and other important outcomes in congestive heart failure (CHF) patients but has not been examined as a predictor of mortality risk in this population. Given the well-known difficulties in managing CHF, we hypothesized that spirituality would be associated with lower mortality risk, controlling for baseline demographics, functional status, health behaviors, and religiousness. Participants were 191 CHF patients (64% male; M age = 68.6 years, SD = 10.1) who completed a baseline survey and were then followed for 5 years. Nearly 1/3 of the sample (32%) died during the study period. Controlling for demographics and health status, smoking more than doubled the risk of mortality, whereas alcohol consumption was associated with slightly lower risk of mortality. Importantly, adherence to healthy lifestyle recommendations was associated with halved mortality risk. Although both religion and spirituality were associated with better health behaviors at baseline in bivariate analyses, a proportional hazard model showed that only spirituality was significantly associated with reduced mortality risk (by 20%), controlling for demographics, health status, and health behaviors. Experiencing spiritual peace, along with adherence to a healthy lifestyle, were better predictors of mortality risk in this sample of CHF patients than were physical health indicators such as functional status and comorbidity. Future research might profitably examine the efficacy of attending to spiritual issues along with standard lifestyle interventions. (c) 2016 APA, all rights reserved).

    High level of physical activity (PA) is associated with great muscle strength and high fracture risk. This prospective controlled population-based study evaluated how a pediatric PA intervention program influenced muscle strength and fracture risk. We carried out a school-based exercise intervention program with 200 min of PA per week for 5 years in 335 girls and 408 boys aged 6-9 years at study start. An age-matched control cohort including 756 girls and 782 boys continued with 60 min of PA per week. We registered fractures during the study period and calculated rate ratio. In a sub-sample, including 74 girls and 107 boys in the intervention and 51 girls and 54 boys in the control group, we measured knee flexion and extension strength by a computerized dynamometer and leg composition by dual energy X-ray absorptiometry. Group comparisons were adjusted for differences in age, baseline value for the measured parameter and changes in height. Children in the intervention group had a rate ratio to sustain a fracture of 1.03 (0.78, 1.36) (mean and 95 % confidence interval) (p = 0.79). The annual gain in flexion peak torque muscle strength was greater in both girls (at 60°/s) [1.1 Nm (0.5, 1.8), p fracture risk.

    Personality disorders are associated with dysfunction in a variety of areas. Recent longitudinal research has shown that personality disorders are also predictive of problems later in life, as well as of poor response to treatment of depression and anxiety. This study assessed whether personality...... a self-report questionnaire designed to measure symptoms of psychiatric illness, the Symptoms Checklist-90 (SCL-90), during and five years after treatment. Concurrently, features of all personality disorders, except histrionic, were associated with SCL-90 score. At five-year follow-up, most personality...... at follow-up. After controlling for abstinence and baseline score, only borderline personality disorder features remained associated with SCL-90 score at follow-up.

    Despite the centrality of nutrition in the management of type 1 diabetes, the association of diet quality and macronutrient distribution with glycemic control is ambiguous. This study examined longitudinally the association of dietary intake with multiple indicators of glycemic control in youth with type 1 diabetes participating in a behavioral nutrition intervention study. Participants in a randomized clinical trial of a behavioral nutrition intervention [n = 136; mean ± SD age: 12.8 ± 2.6 y; glycated hemoglobin (HbA1c): 8.1% ± 1.0%; 69.1% using an insulin pump] completed 3-d diet records at baseline and months 3, 6, 9, 12, and 18; masked continuous glucose monitoring (CGM) data were obtained concurrently with the use of the Medtronic iPro CGM system. HbA1c was obtained every 3 mo; 1,5-anhydroglucitol was obtained every 6 mo. Linear mixed-effects regression models estimated associations of time-varying dietary intake variables with time-varying glycemic control indicators, controlling for age, height, weight, sex, Tanner stage, diabetes duration, regimen, frequency of blood glucose monitoring, physical activity, and treatment assignment. HbA1c was associated inversely with carbohydrate and natural sugar, and positively with protein and unsaturated fat. 1,5-Anhydroglucitol was associated positively with fiber intake and natural sugar. Greater glycemic control as indicated by ≥1 CGM variable was associated with higher Healthy Eating Index-2005, whole plant food density, fiber, carbohydrate, and natural sugar and lower glycemic index and unsaturated fat. Both overall diet quality and macronutrient distribution were associated with more optimal glycemic control. Associations were more consistent for CGM variables obtained concurrently with dietary intake than for biomarkers of longer-term glycemic control. These findings suggest that glycemic control may be improved by increasing intake of high-fiber, low glycemic-index, carbohydrate-containing foods. This trial

    Purpose: Conformal and intensity modulated radiation therapies have the potential to preserve cognitive outcomes in children with ependymoma; however, functional behavior remains uninvestigated. This longitudinal investigation prospectively examined intelligence quotient (IQ) and adaptive functioning during the first 5 years after irradiation in children diagnosed with ependymoma. Methods and Materials: The study cohort consisted of 123 children with intracranial ependymoma. Mean age at irradiation was 4.60 years (95% confidence interval [CI], 3.85-5.35). Serial neurocognitive evaluations, including an age-appropriate IQ measure and the Vineland Adaptive Behavior Scales (VABS), were completed before irradiation, 6 months after treatment, and annually for 5 years. A total of 579 neurocognitive evaluations were included in these analyses. Results: Baseline IQ and VABS were below normative means (P<.05), although within the average range. Linear mixed models revealed stable IQ and VABS across the follow-up period, except for the VABS Communication Index, which declined significantly (P=.015). Annual change in IQ (-.04 points) did not correlate with annual change in VABS (-.90 to +.44 points). Clinical factors associated with poorer baseline performance (P<.05) included preirradiation chemotherapy, cerebrospinal fluid shunt placement, number and extent of surgical resections, and younger age at treatment. No clinical factors significantly affected the rate of change in scores. Conclusions: Conformal and intensity modulated radiation therapies provided relative sparing of functional outcomes including IQ and adaptive behaviors, even in very young children. Communication skills remained vulnerable and should be the target of preventive and rehabilitative interventions.

    Full Text Available Abstract Background Diabetes is a common disease with self-management a key aspect of care. Large prospective trials have shown that maintaining glycated hemoglobin less than 7% greatly reduces complications but translating this level of control into everyday clinical practice can be difficult. Intensive improvement programs are successful in attaining control in patients with type 2 diabetes, however, many patients experience glycemic relapse once returned to routine care. This early relapse is, in part, due to decreased adherence in self-management behaviors. Objective This paper describes the design of the Glycemic Relapse Prevention study. The purpose of this study is to determine the optimal frequency of maintenance intervention needed to prevent glycemic relapse. The primary endpoint is glycemic relapse, which is defined as glycated hemoglobin greater than 8% and an increase of 1% from baseline. Methods The intervention consists of telephonic contact by a nurse practitioner with a referral to a dietitian if indicated. This intervention was designed to provide early identification of self-care problems, understanding the rationale behind the self-care lapse and problem solve to find a negotiated solution. A total of 164 patients were randomized to routine care (least intensive, routine care with phone contact every three months (moderate intensity or routine care with phone contact every month (most intensive. Conclusion The baseline patient characteristics are similar across the treatment arms. Intervention fidelity analysis showed excellent reproducibility. This study will provide insight into the important but poorly understood area of glycemic relapse prevention.

    To assess sleep patterns in female patients with anorexia nervosa before and after weight restoration. Sleep patterns were measured objectively using a Sense Wear Armband before and after weight restoration in 50 female patients with anorexia nervosa, and in 25 healthy females. At baseline, patients with anorexia nervosa exhibited lower total sleep time and sleep onset latency than controls, the former apparently associated with baseline BMI, duration of illness and age. However, after weight restoration, total sleep time and sleep onset latency were similar to controls, despite the persistence of longer periods of wake after sleep onset. In patients with anorexia nervosa, total sleep time and sleep onset latency appears to be reduced. This sleep disturbance seems to be influenced by the duration and severity of malnutrition, and appears to normalize with weight restoration. Even though a discontinuous sleep pattern seems to persist, this finding should be discussed with patients. Copyright © 2016 John Wiley & Sons, Ltd and Eating Disorders Association.

    Full Text Available Abstract Background Vitamin D level is inversely associated with tuberculosis (TB and diabetes (DM. Vitamin D could be a mediator in the association between TB and DM. We examined the associations between vitamin D, TB and DM. Methods Consecutive adults with TB and sex- and age-matched volunteers were included in a case-control study in Dar es Salaam, Tanzania. Glycemia and total vitamin D (25(OHD were measured at enrolment and after TB treatment in cases. The association between low 25(OHD (<75 nmol/l and TB was evaluated by logistic regression adjusted for age, sex, body mass index, socioeconomic status, sunshine hours, HIV and an interaction between low 25(OHD and hyperglycemia. Results The prevalence of low 25(OHD was similar in TB patients and controls (25.8 % versus 31.0 %; p = 0.22. In the subgroup of patients with persistent hyperglycemia (i.e. likely true diabetic patients, the proportion of patients with low 25(OHD tended to be greater in TB patients (50 % versus 29.7 %; p = 0.20. The effect modification by persistent hyperglycemia persisted in the multivariate analysis (pinteraction = 0.01. Conclusions Low 25(OHD may increase TB risk in patients with underlying DM. Trials should examine if this association is causal and whether adjunct vitamin D therapy is beneficial in this population.

    Full Text Available Difficulties in cognitive control including inhibitory control (IC are related to the pathophysiology of several psychiatric conditions. In healthy subjects, IC efficiency in childhood is a strong predictor of academic and professional successes later in life. The dorsal anterior cingulate cortex (ACC is one of the core structures responsible for IC. Although quantitative structural characteristics of the ACC contribute to IC efficiency, the qualitative structural brain characteristics contributing to IC development are less-understood. Using anatomical magnetic resonance imaging, we investigated whether the ACC sulcal pattern at age 5, a stable qualitative characteristic of the brain determined in utero, explains IC at age 9. 18 children performed Stroop tasks at age 5 and age 9. Children with asymmetrical ACC sulcal patterns (n = 7 had better IC efficiency at age 5 and age 9 than children with symmetrical ACC sulcal patterns (n = 11. The ACC sulcal patterns appear to affect specifically IC efficiency given that the ACC sulcal patterns had no effect on verbal working memory. Our study provides the first evidence that the ACC sulcal pattern – a qualitative structural characteristic of the brain not affected by maturation and learning after birth – partially explains IC efficiency during childhood.

    Purpose To explore future diagnosis-specific sickness absence and disability pension among women with breast cancer compared with women without breast cancer. Also, to examine associations with disease-related and sociodemographic factors among those with breast cancer. Methods Longitudinal register data on 3,547 women living in Sweden (age 20 to 65 years) who were first diagnosed with breast cancer in 2005, and a matched comparison cohort (n = 14,188), were analyzed for the annual prevalence of diagnosis-specific sickness absence and disability pension over 5 years. Logistic regressions were used to explore associations of disease-related and sociodemographic factors with future sickness absence and disability pension among women with breast cancer. Results Immediately after being diagnosed with breast cancer, the proportion of women with sickness absence was high but decreased continuously from the 1st through 5th year after diagnosis (71%, 40%, 30%, 22%, and 19%, respectively). In comparison, the range for women without breast cancer was 17% to 11%, respectively. The higher prevalence of sickness absence after breast cancer was mainly a result of breast cancer diagnosis, not a mental diagnosis, or other somatic diagnoses. Advanced cancer at diagnosis, > 90 days sickness absence before diagnosis, low education, and being born outside Sweden were associated with higher odds ratios for sickness absence and disability pension (odds ratio range, 1.40 to 6.45). Conclusion The level of sickness absence increased substantially in women with breast cancer during the first year after diagnosis and approached the level of breast cancer-free women in the following years; however, even in the first year, most women were not on sickness absence for a substantial time, and even in high-risk groups, many were not on sickness absence or disability pension in the following years. Information about relatively low future sickness absence and disability pension levels can be used by

    The stress of a breast cancer diagnosis and its treatment can produce a variety of psychosocial sequelae including impaired immune responses. Mindfulness Based Stress Reduction (MBSR) is a structured complementary program that incorporates meditation, yoga and mind-body exercises. Despite promising empirical evidence for the efficacy of MBSR, there is a need for randomized controlled trials (RCT). There is also a need for RCTs investigating the efficacy of psychosocial interventions on mood disorder and immune response in women with breast cancer. Therefore, the overall aim is to determine the efficacy of a Mindfulness Based Stress Reduction (MBSR) intervention on well-being and immune response in women with breast cancer. In this RCT, patients diagnosed with breast cancer, will consecutively be recruited to participate. Participants will be randomized into one of three groups: MBSR Intervention I (weekly group sessions + self-instructing program), MBSR Intervention II (self-instructing program), and Controls (non-MBSR). Data will be collected before start of intervention, and 3, 6, and 12 months and thereafter yearly up to 5 years. This study may contribute to evidence-based knowledge concerning the efficacy of MBSR to support patient empowerment to regain health in breast cancer disease. The present study may contribute to evidence-based knowledge concerning the efficacy of mindfulness training to support patient empowerment to regain health in a breast cancer disease. If MBSR is effective for symptom relief and quality of life, the method will have significant clinical relevance that may generate standard of care for patients with breast cancer.

    CONTEXT Suicide bereavement remains understudied and poorly understood. OBJECTIVES To examine outcomes of parents bereaved by the suicide death of their offspring and to compare these with both nonbereaved parent controls and parents who had offspring die in a motor vehicle crash (MVC). DESIGN Population-based case-control study. Suicide-bereaved parents were compared with nonbereaved matched control parents in the general population (n = 1415) and with MVC-bereaved parents (n = 1132) on the rates of physician-diagnosed mental and physical disorders, social factors, and treatment use in the 2 years after death of the offspring. Adjusted relative rates (ARRs) were generated by generalized estimating equation models and adjusted for confounding factors. SETTING Manitoba, Canada. PARTICIPANTS All identifiable parents who had an offspring die by suicide between 1996 and 2007 (n = 1415). MAIN OUTCOME MEASURES Mental and physical disorders, social factors, and treatment use. RESULTS Suicide bereavement was associated with an increased rate of depression (ARR, 2.14; 95% CI, 1.88-2.43), anxiety disorders (ARR, 1.41; 95% CI, 1.24-1.60), and marital breakup (ARR, 1.18; 95% CI, 1.13-1.23) in the 2 years after the suicide of an offspring, as compared with the 2 years prior to the death. Suicide-bereaved and MVC-bereaved parents had very few differences on predeath to postdeath outcomes. Depression rate increases were greater for MVC-bereaved parents (19.9%) compared with suicide-bereaved parents (15.9%; P = .005), whereas suicide-bereaved parents had higher rate increases of hospitalization for mental illness (P = .049). Suicide-bereaved parents were more likely than their MVC-bereaved counterparts to have depression (ARR, 1.30; 95% CI, 1.06-1.61), physical disorders (ARR, 1.32; 95% CI, 1.19-1.45), and low income (ARR, 1.34; 95% CI, 1.18-1.51) before their offspring's death. CONCLUSIONS Suicide bereavement is associated with adverse mental health and social outcomes

    The objective of this study was to examine mental disorders and treatment use among bereaved siblings in the general population. Siblings (N=7243) of all deceased children in the population of Manitoba, Canada who died between 1984 and 2009 were matched 1:3 to control siblings (N=21,729) who did not have a sibling die in the study period. Generalized estimating equations were used to compare the two sibling groups in the two years before and after the index child's death on physician-diagnosed mental disorders and treatment utilization, with adjustment for confounding factors including pre-existing mental illness. Analyses were stratified by age of the bereaved (rise in depression rates from pre-death to post-death was significantly higher for siblings aged under 13 (pWorld Psychiatric Association.

    In this study, we investigated whether (a) animals demonstrating the learned helplessness effect during an escape contingency also show learning deficits under positive reinforcement contingencies involving stimulus control and (b) the exposure to positive reinforcement contingencies eliminates the learned helplessness effect under an escape contingency. Rats were initially exposed to controllable (C), uncontrollable (U) or no (N) shocks. After 24h, they were exposed to 60 escapable shocks delivered in a shuttlebox. In the following phase, we selected from each group the four subjects that presented the most typical group pattern: no escape learning (learned helplessness effect) in Group U and escape learning in Groups C and N. All subjects were then exposed to two phases, the (1) positive reinforcement for lever pressing under a multiple FR/Extinction schedule and (2) a re-test under negative reinforcement (escape). A fourth group (n=4) was exposed only to the positive reinforcement sessions. All subjects showed discrimination learning under multiple schedule. In the escape re-test, the learned helplessness effect was maintained for three of the animals in Group U. These results suggest that the learned helplessness effect did not extend to discriminative behavior that is positively reinforced and that the learned helplessness effect did not revert for most subjects after exposure to positive reinforcement. We discuss some theoretical implications as related to learned helplessness as an effect restricted to aversive contingencies and to the absence of reversion after positive reinforcement.

    The present study examined the longitudinal relations between illness perceptions and asthma control and emotional problems (i.e., anxiety, depression, stress), respectively, in adolescents with asthma. Furthermore, the mediating effects of asthma-specific coping strategies on these relations were examined, as specified in the Common Sense Model (CSM). In 2011, 2012, and 2013, adolescents (aged 10-15) with asthma were visited at home (N=253) and completed questionnaires about their illness perceptions, asthma-specific coping strategies, asthma control, symptoms of anxiety and depression, and perceived stress. Path analyses were used to examine the direct relations of illness perceptions with asthma control and emotional problems and the mediating effects of coping strategies cross-sectionally and longitudinally. Perceptions of less perceived control and attributing more complaints to asthma were associated with better asthma control. Perceptions of more concern, less coherence, and increased influence of asthma on emotional well-being were associated with more emotional problems. Longitudinally, perceptions of more treatment control and fewer concerns predicted less emotional problems over time. More worrying mediated the cross-sectional relation between perceiving more concern about asthma and less asthma control and the longitudinal relation between perceiving more concern about asthma and more emotional problems. Illness perceptions were associated with asthma control and emotional problems; however, over time, illness perceptions only predicted changes in emotional problems. Most coping strategies did not mediate the relation between illness perceptions and outcomes. Interventions aimed to change illness perceptions in adolescents with asthma could decrease emotional problems. Copyright © 2014 Elsevier Inc. All rights reserved.

    The importance of perioperative cognitive decline has long been debated. We recently demonstrated a significant correlation between perioperative cognitive decline and long-term cognitive dysfunction. Despite this association, some still question the importance of these changes in cognitive function to the quality of life of patients and their families. The purpose of our investigation was to determine the association between cognitive dysfunction and long-term quality of life after cardiac surgery. After institutional review board approval and patient informed consent, 261 patients undergoing cardiac surgery with cardiopulmonary bypass were enrolled and followed for 5 years. Cognitive function was measured with a battery of tests at baseline, discharge, and 6 weeks and 5 years postoperatively. Quality of life was assessed with well-validated, standardized assessments at the 5-year end point. Our results demonstrate significant correlations between cognitive function and quality of life in patients after cardiac surgery. Lower 5-year overall cognitive function scores were associated with lower general health and a less productive working status. Multivariable logistic and linear regression controlling for age, sex, education, and diabetes confirmed this strong association in the majority of areas of quality of life. Five years after cardiac surgery, there is a strong relationship between neurocognitive functioning and quality of life. This has important social and financial implications for preoperative evaluation and postoperative care of patients undergoing cardiac surgery.

    The purpose of this multicenter study was to evaluate the impact of hand burn injury in preschool children younger than 5 years on health-related quality of life, including both physical and psychosocial function, in the 5 years after burn injury. This prospective case series assessed children younger than 5 years admitted to four pediatric burn centers. Each child's family completed the American Burn Association/Shriners Hospitals for Children Burn Outcome Questionnaire (BOQ), a validated and reliable assessment tool, which measures the physical and psychosocial functioning of the child with burn injury ages 0 year to 5 years, at baseline, 3, 6, 12, 18, 24, 36, and 48 months after discharge. Multivariate models controlling for sociodemographic and clinical characteristics were developed, and recovery curves were generated for the time since burn using generalized estimating equations with random effects. A cohort of 438 patients was followed up prospectively. Mean (SD) patient age was 2.2 (1.2) years, mean (SD) total body surface area (TBSA) was 28% (22.4%), and 19% had inhalation injury. Children with hand burns had lower scores in most of the areas tested, with the most pronounced and significant differences were in fine motor function, gross motor function, and appearance. These findings applied to both small (burns. The most profound impact of hand burns was noted in fine and gross motor function during the 4 years of follow-up. Children with hand burns have significantly worse outcomes than do children with burns in other areas.

  18. No sustained attention differences in a longitudinal randomized trial comparing mindfulness based stress reduction versus active control.

    Donal G MacCoon

    Full Text Available Mindfulness Based Stress Reduction (MBSR is a secular form of meditation training. The vast majority of the extant literature investigating the health effects of mindfulness interventions relies on wait-list control comparisons. Previous studies have found that meditation training over several months is associated with improvements in cognitive control and attention.We used a visual continuous performance task (CPT to test the effects of eight weeks of mindfulness training on sustained attention by comparing MBSR to the Health Enhancement Program (HEP, a structurally equivalent, active control condition in a randomized, longitudinal design (ClinicalTrials.gov, NCT01301105 focusing on a non-clinical population typical of MBSR participants. Researchers were blind to group assignment. 63 community participants were randomized to either MBSR (n = 31 or HEP (n = 32. CPT analyses were conducted on 29 MBSR participants and 25 HEP participants. We predicted that MBSR would improve visual discrimination ability and sustained attention over time on the CPT compared to HEP, with more home practice associated with greater improvements. Our hypotheses were not confirmed but we did find some evidence for improved visual discrimination similar to effects in partial replication of other research. Our study had sufficient power to demonstrate that intervention groups do not differ in their improvement over time in sustained attention performance. One of our primary predictions concerning the effects of intervention on attentional fatigue was significant but not interpretable.Attentional sensitivity is not affected by mindfulness practice as taught in MBSR, but it is unclear whether mindfulness might positively affect another aspect of attention, vigilance. These results also highlight the relevant procedural modifications required by future research to correctly investigate the role of sustained attention in similar samples.ClinicalTrials.gov, NCT

    Dental decay affects many children, especially those from the lower socioeconomic classes. In this cross-sectional study designed to investigate the role played by sociodemographic factors, parental attitudes, and monitoring points, which are an indicator of personal perception of what controls individual health, on the prevalence of tooth decay among 5-year-old pre-school children living in a midsized city in São Paulo, Brazil. The ceo-d index of 426 children was assessed; the parents reported sociodemographic characteristics and completed two questionnaires concerning monitoring points and parental attitudes. The results show that 52.35% of the children had decay; higher levels of severe decay were observed among lower E-F socioeconomic classes. Higher socioeconomic status and low externality appear to be protective factors. Low parental internality emerged as a risk factor for decay in primary teeth, possibly because the mother expects or delegates the action to others, delaying care. Parental perceptions of control over a child's health seem to impact preventive care and, consequently, the level of tooth decay among children.

  20. Procedural Metacognition and False Belief Understanding in 3- to 5-Year-Old Children.

    Directory of Open Access Journals (Sweden)

    Stéphane Bernard

    Full Text Available Some studies, so far limited in number, suggest the existence of procedural metacognition in young children, that is, the practical capacity to monitor and control one's own cognitive activity in a given task. The link between procedural metacognition and false belief understanding is currently under theoretical discussion. If data with primates seem to indicate that procedural metacognition and false belief understanding are not related, no study in developmental psychology has investigated this relation in young children. The present paper aims, first, to supplement the findings concerning young children's abilities to monitor and control their uncertainty (procedural metacognition and, second, to explore the relation between procedural metacognition and false belief understanding. To examine this, 82 3- to 5-year-old children were presented with an opt-out task and with 3 false belief tasks. Results show that children can rely on procedural metacognition to evaluate their perceptual access to information, and that success in false belief tasks does not seem related to success in the task we used to evaluate procedural metacognition. These results are coherent with a procedural view of metacognition, and are discussed in the light of recent data from primatology and developmental psychology.

    Full Text Available This paper presents an investigation of mitigation of longitudinal buffeting responses of the Jiashao Bridge, the longest multispan cable-stayed bridge in the world. A time-domain procedure for analyzing buffeting responses of the bridge is implemented in ANSYS with the aeroelastic effect included. The characteristics of longitudinal buffeting responses of the six-tower cable-stayed bridge are studied in some detail, focusing on the effects of insufficient longitudinal stiffness of central towers and partially longitudinal constraints between the bridge deck and part of bridge towers. The effectiveness of viscous fluid dampers on the mitigation of longitudinal buffeting responses of the bridge is further investigated and a multiobjective optimization design method that uses a nondominating sort genetic algorithm II (NSGA-II is used to optimize parameters of the viscous fluid dampers. The results of the parametric investigations show that, by appropriate use of viscous fluid dampers, the top displacements of central towers and base forces of bridge towers longitudinally restricted with the bridge deck can be reduced significantly, with hampering the significant gain achieved in the base forces of bridge towers longitudinally unrestricted with the bridge deck. And the optimized parameters for the viscous fluid dampers can be determined from Pareto-optimal fronts using the NSGA-II that can satisfy the desired performance requirements.

    Findings on the relation of maternal verbal teaching strategies to children’s effortful control (EC; i.e., self-regulation) are limited in quantity and somewhat inconsistent. In this study, children’s EC was assessed at 18, 30, and 42 months (ns = 255, 229, and 209, respectively) with adults’ reports and a behavioral measure. Mothers’ verbal teaching strategies were assessed while the mother and child worked on a task together. Children’s general vocabulary also was measured. In a structural panel model taking into account prior levels of constructs and correlations within time, as well as the relations of EC and teaching strategies to children’s vocabulary, socioeconomic status, age, and sex of the child, 18-month EC positively predicted mothers’ 30-month cognitive assistance and questioning strategies and negatively predicted 30-month maternal directive strategies. In addition, high 30-month EC predicted greater 42-month maternal cognitive assistance and fewer directive strategies. Thus, mothers’ teaching strategies were predicted by individual differences in self-regulatory skills, supporting potential evocative child effects on mothers’ teaching strategies. PMID:20822239

    The 3Rs guideline is the gold standard for ethics in animal experimentation. Two of those rules, namely refinement and reduction, require further improvement. The objective of this study was to define pathways to better compliance with these prerequisites. Two methods which move us in this direction are: (1) using small animal imaging techniques for pancreatic ductal adenocarcinoma (PDAC) follow-up and (2) reduction of the number of control animals included in a study of PDAC progression under treatment. Firstly, we used MicroCT scan to diagnose events showing PDAC progression prior to any clinical symptoms to thereby define more humane endpoints identifiable before any painful phenomenon is observed. Secondly, in order to test the hypothesis of using a reference control group in all preclinical studies of a new treatment of PDAC, we investigated the stability of the results obtained with the control groups in three successive identical studies comparing placebo and gemcitabine in tumor-bearing Lewis rats. Two imaging endpoints were found. The first was the observation of a liver metastasis assessing PDAC diffusion and, earlier than liver metastasis, the presence of bands of fluid along the flanks, with more or less a medial displacement of bowel and solid viscera, reflecting a peritoneal ascites. Results of the longitudinal follow-up of rats in the gemcitabine study revealed heterogeneity in the survival rate in the three control groups, as opposed to the survival rate in the three treated groups which did not differ statistically. As a result, the significance of improved survival with chemotherapy varied greatly according to the control group used for the comparison, ranging from no impact to a highly significant effect. The early detection by the means of animal imaging of one or more signs indicating the onset of a critical step in the development of the disease (e.g., ascites or/and metastasis) allows the researcher to prevent the occurrence of animal pain

    The Indian Peninsula is generally considered as a tectonically stable region, where ancient rocks, rivers and land surfaces predominate. In some parts of this ancient landscape, however, the role of tectonic landsculpting is strongly indicated by the presence of youthful topography and historical seismic activity. The present study is primarily focused on the middle domain of the Kaveri River, which displays such youthful features. The tectonic controls on this cratonic river were evaluated on the basis of the investigations of the longitudinal profiles, morphotectonic indices of active tectonics, and fluvial records. The presence of steep channel gradients, prominent knickpoints, hanging valleys, narrow bedrock gorges, and channel-in-channel morphology imply rapid erosion rates in the middle domain of the basin in response to active deformation, particularly in the reach defined by two major active faults - the Kollegal-Sivasamudram Fault and the Mekedatu Fault. Further, considering the remarkably low modern and long-term denudation rates and OSL ages of the alluvial deposits (30-40 ka), the tectonically-driven rejuvenation does not appear to be geologically recent as postulated by earlier workers.

Young offenders at the time of admission (6.61, 2.58-15.2, at 6 months (3.12, 1.81-10.1, and at 12 months (5.29, 1.98-13.3 reported statistically higher levels of total mental health problems than adolescents in a community sample. CONCLUSIONS: Young offenders have a high rate of mental and behavioral disorders. In the detention period, aggressive behavior, self-destructive/identity, and externalizing of problems improved while withdrawn, anxious or depressed, and internalizing of problems worsened.

    Iron deficiency (ID) is the most common cause of anemia worldwide. The prevalence is highest among preschool-aged children. Iron is widely administered to children with or at risk for ID, but evidence of benefit among 2- to 5-year-old children has not been evaluated by systematic review. We summarize the evidence for the benefit and safety of daily iron supplementation with regard to hematologic, growth, and cognitive parameters in 2 to 5 year olds. Electronic databases, regional databases, thesis repositories, gray literature, and references of studies and previous reviews were searched. We included randomized controlled trials that compared daily oral iron supplementation with control in 2 to 5 year olds. A random-effects meta-analysis was used to synthesize predefined outcomes reported by at least 2 studies. Of 9169 references, 15 studies met the inclusion criteria, none of which were at low risk of bias. Children receiving iron supplementation had a mean end point hemoglobin of 6.97 g/L (P < .00001; I(2) = 82%) greater than controls, whereas mean end point ferritin was 11.64 µg/L (P < .0001; I(2) = 48%) greater. No trials reported the effects of iron supplementation on ID or iron deficiency anemia, and only one reported on anemia. Limited evidence suggested that iron supplementation produced a small improvement in cognitive development but had no effect on physical growth. In 2 to 5 year olds, daily iron supplementation increases hemoglobin and ferritin. There is a concerning lack of data on the effect of iron supplementation on clinically important outcomes including anemia, ID anemia, ID, and cognitive development. Additional interventional studies in this age group are needed.

    Young children learn multiple cognitive skills concurrently (e.g., language and music). Evidence is limited as to whether and how learning in one domain affects that in another during early development. Here we assessed whether exposure to a tone language benefits musical pitch processing among 3-5-year-old children. More specifically, we compared the pitch perception of Chinese children who spoke a tone language (i.e., Mandarin) with English-speaking American children. We found that Mandarin-speaking children were more advanced at pitch processing than English-speaking children but both groups performed similarly on a control music task (timbre discrimination). The findings support the Pitch Generalization Hypothesis that tone languages drive attention to pitch in nonlinguistic contexts, and suggest that language learning benefits aspects of music perception in early development.

    The effect of biochar application on soil friability and aggregate stability of loamy soil was studied at Brawijaya University field experimental station, Jatikerto, Malang, Indonesia. The soil has been planted with cassava for 4 years continuously and 1 year planted with maiz. The biochar applied was made from cassava stem and farm yard manure. It was found that biochar application, either made from cassava stem or farm yard manure improved soil qualities. Soil applied with biochar was more friable compared to that of the no biochar soil, although biochar application did not influence Atterberg limits. It seems that the higher friability of biochar applied soil was associated with the higher soil organic matter. It was found that until 5 years application, the biochar treated soil had a higher soil organic matter content. Soil applied with biochar possessed a better soil aggregate stability, both dry and wet stability. This was shown by the higher aggregate mean weight diameter (MWD) of biochar applied soil. The cassava biochar applied soil had MWD of 2.22 mm (dry stability) and 1.56 mm (wet stability), whereas the control soil had MWD of 1.45 mm (dry stability) and 1.25 (wet stability). There was a significant positive correlation between soil friability and dry aggregate stability. The biochar applied soils also had higher soil permeability. Key words: soil qualities, soil physical properties, Atterberg limits, hydraulic conductivity

    Objective: To investigate the change in mortality of congenital malformation in children aged mortality of congenital malformation in children aged mortality rate of congenital malformation in the children s decreased from 1.909‰ in 2006 to 0.703‰ in 2015, the decrease rate was 63.17%. The decrease rate was highest in neonates (71.50%) (χ(2)=57.993, P0.05), the mortality rates of congenital malformation in the children showed a downward trend in outer suburban area and suburban area (χ(2) =40.637 and 50.646, P0.05). In the leading causes of deaths from congenital malformation, the mortality of congenital heart disease, neural tube defects and digestive tract atresia decreased obviously (χ(2)=70.868, 18.431 and 9.225, P0.05). There was an obvious area specific difference between the deaths of congenital heart disease and the deaths of neural tube defects, the mortality was higher in outer suburbs than in suburban and urban area (χ(2)=45.783 and 6.649, Pmortality rate of children with congenital malformation in Beijing has declined year by year, it is still the main cause of deaths in children under 5 years old, and the prevention and control of related diseases should be strengthened.

    The primary purpose of this study was to examine the dimensionality and reliability of letter writing skills in preschool children with the aim of determining whether a sequence existed in how children learn to write the letters of the alphabet. Additionally, we examined gender differences in the development of letter writing skills. 471 children aged 3 to 5 years old completed a letter writing task. Results from factor analyses indicated that letter writing represented a unidimensional skill. Similar to research findings that the development of letter-names and letter-sound knowledge varies in acquisition, our findings indicate that the ability to write some letters is acquired earlier than the ability to write other letters. Although there appears to be an approximate sequence for the easiest and most difficult letters, there appears to be a less clear sequence for letters in the middle stages of development. Overall, girls had higher letter writing scores compared to boys. Gender differences regarding difficulty writing specific letters was less conclusive; however, results indicated that when controlling for ability level, girls had a higher probability of writing a letter correctly than boys. Implications of these findings for the assessment and instruction of letter writing are discussed.

    Screening and preventive interventions by primary care providers could improve outcomes related to early childhood caries. The objective of this study was to update the 2004 US Preventive Services Task Force systematic review on prevention of caries in children younger than 5 years of age. Searching Medline and the Cochrane Library (through March 2013) and reference lists, we included trials and controlled observational studies on the effectiveness and harms of screening and treatments. One author extracted study characteristics and results, which were checked for accuracy by a second author. Two authors independently assessed study quality. No study evaluated effects of screening by primary care providers on clinical outcomes. One good-quality cohort study found pediatrician examination associated with a sensitivity of 0.76 for identifying a child with cavities. No new trials evaluated oral fluoride supplementation. Three new randomized trials were consistent with previous studies in finding fluoride varnish more effective than no varnish (reduction in caries increment 18% to 59%). Three trials of xylitol were inconclusive regarding effects on caries. New observational studies were consistent with previous evidence showing an association between early childhood fluoride use and enamel fluorosis. Evidence on the accuracy of risk prediction instruments in primary care settings is not available. There is no direct evidence that screening by primary care clinicians reduces early childhood caries. Evidence previously reviewed by the US Preventive Services Task Force found oral fluoride supplementation effective at reducing caries incidence, and new evidence supports the effectiveness of fluoride varnish in higher-risk children.

  17. ASSESSMENT OF A 5-YEAR-OLD REHABILITATED RIPARIAN FOREST: IS IT ALREADY SUSTAINABLE?

    Full Text Available ABSTRACTAs important as the establishment of projects of ecological restoration is its assessment post-implementation to know whether the area is becoming self-sustainable or need to be redirected. In this way, this study aimed to know the current situation of a 5-year-old rehabilitated riparian forest,inserted in an anthropogenic impacted region,at the das Velhas River, Minas Gerais State, studying the canopy openness and recruitment of seedlings as plant indicators. 15 plots were allocated in the forest, where hemispherical photographs were taken to analyze the canopy openness and evaluate all seedlings from 0.30 m to 1.30 m height.Canopy openness ranged from 23.7% to 38.8% between seasons and only 192 seedlings were found,from 13 species, five of them exotic and aggressive. Although canopy openness was low, it seems that lateral penetration of light has been favoring the development and dominancy of plants from invasive species, whereas few native ones have been recruited. The exotic/invasive plants may compromise the success of restoration mainly by competition with native planted species. The outcomes evidenced an unsustainability of the riparian forest and the requirement of some management actions to control exotic and invasive plants and ensure the preservation of the area and its ecological roles over time.

    Full Text Available Background. Short implants have become popular in the reconstruction of jaws, especially in cases with limited bone height. Shorter implants, those with locking tapers and plateau root shapes, tend to have longer survival times. We retrospectively investigated the cumulative survival rates of Bicon short implants (<8 mm according to patient variables over a 5-year period. Materials and Methods. This study included 111 consecutively treated patients with 371 implants supporting fixed or removable prosthetics. Data were evaluated to acquire cumulative survival rates according to gender, age, tobacco use, surgical procedure, bone quality, and restoration type. Statistics were performed using chi-square, Mann-Whitney, and Kruskal Wallis H tests. Results. The survival rate was 97.3% with, on average, 22.8 months of follow-up. Patients older than 60 years had higher failure rate than the other age groups (P<0.05. Placed region, age, and bone quality had adverse effects on survival rate in the <8 mm implant group with statistically significant difference (P<0.05. Conclusions. Approximately 23-month follow-up data indicate that short implants with locking tapers and plateau-type roots have comparable survival rates as other types of dental implants. However, due to limitations of study, these issues remain to be further investigated in future randomized controlled clinical trials.

    We evaluated the "extended" long-term (5 years) functional outcomes in obstetric brachial plexus injury (OBPI) patients, who underwent triangle tilt surgery between February 2005 and January 2008. Twenty two children (9 girls and 13 boys, mean age at surgery was 5.8 years; ranging 2.1-11.8 years old), who initially presented with medial rotation contracture and scapula deformity secondary to obstetric brachial plexus injury were included in this study. Functional movements were evaluated pre-operatively, and 5 years following triangle tilt surgery by modified Mallet scale. Here, we report long-term (5 years) follow-up of triangle tilt surgery for 22 OBPI patients. Upper extremity functional movements such as, external rotation (2.5±0.6 to 4.1±0.8, ptriangle tilt surgery improved all shoulder functions significantly, and maintained over the extended long-term (5 years) in these patients.

    To evaluate the efficacy and safety of a new, low-dose levonorgestrel intrauterine contraceptive system (LNG-IUS 12) for up to 5 years of use. In this Phase III study, 2885 nulliparous and parous women aged 18-35 years were randomized to LNG-IUS 8 or LNG-IUS 12 for 3 years. After 3 years, women using LNG-IUS 12 could continue for up to 2 additional years (5 years total). The primary outcome was occurrence of pregnancy (Pearl Index). Secondary outcomes included safety, bleeding, dysmenorrhea, discontinuations, and user satisfaction. From August 2007 through May 2008, out of 2885 women who were enrolled, 1453 were randomized to LNG-IUS 12. Placement was attempted in 1452/1453 (full analysis set). Mean age at baseline was 27.1 years; 39.5% were nulliparous. The cumulative 5-year Pearl Index (PI) was 0.29; the 5-year cumulative failure rate was 1.4%. The 5-year PI for ectopic pregnancy was 0.18. Over 5 years, 55.3% of women reported study drug-related treatment-emergent adverse events (TEAEs). Crude incidences of pelvic inflammatory disease, uterine perforation, and complete/partial LNG-IUS 12 expulsion were 0.6%, 0.2%, and 3.7%, respectively. Women using LNG-IUS 12 generally experienced less frequent bleeding over time. The incidence of amenorrhea during the last 90-day reference interval (end of Year 5) was 22.6%. Overall, 870 (59.9%) and 550 (37.9%) women completed 3 and 5 years of treatment, respectively; 77.8% of women who entered the extension phase completed 5 years of use. Over 5 years, 22.6% discontinued due to TEAEs, including 13 women who discontinued due to pregnancy; 76 discontinued due to bleeding problems including amenorrhea; and 163 discontinued due to desire for pregnancy, 71.2% of whom conceived within 12 months. In this study including parous and nulliparous women, LNG-IUS 12 was highly effective over 5 years of use and associated with a favorable safety profile. LNG-IUS 12 offers women a low-dose contraceptive option for up to 5 years. Copyright

    2017-06-01

    Few studies have examined Manual Motor Speed (MMS) in bipolar disorder (BD). The aim of this longitudinal, family study was to explore whether dysfunctional MMS represents a neurocognitive endophenotype of BD. A sample of 291 subjects, including 131 BD patients, 77 healthy first-degree relatives (BD-Rel), and 83 genetically-unrelated healthy controls (HC), was assessed with the Finger-Tapping Test (FTT) on three occasions over a 5-year period. Dependence of FTT on participants´ age was removed by means of a lineal model of HC samples, while correcting simultaneously the time and learning effect. Differences between groups were evaluated with an ANOVA test. The patients' performance was significantly worse than that of HC over time (p≤0.006), and these deficits remained when non-euthymic BD patients (n=9) were excluded from analysis. Some significant differences between BD patients and BD-Rel (p≤0.037) and between BD-Rel and HC (p≤0.033) were found, but they tended to disappear as time progressed (p≥0.057). Performance of the BD-Rel group was intermediate to that of BD and HC. Most sociodemographic and clinical variables did not affect these results in patients. (p≥0.1). However, treatment with carbamazepine and benzodiazepines may exert a iatrogenic effect on MMS performance (p≤0.006). Only right-handed subjects were included in this study. Substantial attrition over time was detected. There were significant differences between the patients´ MMS performance and that of healthy relatives and controls, regardless of most clinical and sociodemographic variables. Dysfunctional MMS could be considered an endophenotype of BD. Further studies are needed to rule out possible iatrogenic effects of some psychopharmacological treatments.

    2017-01-01

    Low Earth orbit space environment conditions, including ultraviolet radiation, thermal cycling, and atomic oxygen exposure, can cause degradation of exterior spacecraft materials over time. Radiation and thermal exposure often results in bond- breaking and embrittlement of polymers, reducing mechanical strength and structural integrity. An experiment called the Flexural Stress Effects Experiment (FSEE) was flown with the objective of determining the role of space environmental exposure on the degradation of polymers under flexural stress. The FSEE samples were flown in the wake orientation on the exterior of International Space Station for 1.5 years. Twenty-four samples were flown: 12 bent over a 0.375 in. mandrel and 12 were over a 0.25 in. mandrel. This was designed to simulate flight configurations of insulation blankets on spacecraft. The samples consisted of assorted polyimide and fluorinated polymers with various coatings. Half the samples were designated for bend testing and the other half will be tensile tested. A non-standard bend-test procedure was designed to determine the surface strain at which embrittled polymers crack. All ten samples designated for bend testing have been tested. None of the control samples' polymers cracked, even under surface strains up to 19.7%, although one coating cracked. Of the ten flight samples tested, seven show increased embrittlement through bend-test induced cracking at surface strains from 0.70%to 11.73%. These results show that most of the tested polymers are embrittled due to space exposure, when compared to their control samples. Determination of the extent of space induced embrittlement of polymers is important for designing durable spacecraft.

    2016-01-01

    Full Text Available Introduction: There is a gradual increasing trend in childhood cancers in India and pediatric palliative care in India is an emerging specialty. Prescribing pain and symptom control drugs in children with cancer requires knowledge of palliative care formulary, dosing schedules, and prescription guidelines. This study is a retrospective audit of prescribing practices of a specialist palliative care service situated in a tertiary cancer center. Methods: A total of 1135 medication records of children receiving specialist pediatric palliative care services were audited for 5 years (2010-2014 to evaluate prescribing practices in children with advanced cancer. Results: A total of 51 types of drugs were prescribed with an average of 4.2 drugs per prescription. 66.9% of the prescriptions had paracetamol, and 33.9% of the prescriptions had morphine. Most common nonsteroidal anti-inflammatory drugs prescribed was ibuprofen (23.9%, and more than 50% of the prescriptions had aperients. The most commonly prescribed aperient was a combination of liquid paraffin and sodium-picosulfate. Dexamethasone was prescribed in 51.9% of patients and in most cases this was part of oral chemotherapy regimen. Generic names in prescription were used only in 33% of cases, and adverse effects of the drugs were documented in only 9% of cases. In 25% of cases, noncompliance to the WHO prescription guidelines was seen, and patient compliance to prescription was seen in 40% of cases. Conclusions: Audit of the prescribing practices in specialist pediatric palliative care service shows that knowledge of pediatric palliative care formulary, rational drug use, dosing, and prescribing guidelines is essential for symptom control in children with advanced life-limiting illness. Noncompliance to WHO prescribing guidelines in one fourth of cases and using nongeneric names in two-thirds of prescription indicates poor prescribing practices and warrants prescriber education.

    To assess the effects of hepatitis C virus infection in the first 5 years on fasting glucose, fasting insulin and peripheral insulin resistance. The case-control study was conducted at the Army Medical College, Rawalpindi, from December 2011 to November 2012, and comprised subjects recruited from a government hospital in Rawalpindi. The subjects included known cases of hepatitis C virus infection for at least 5 years, and normal healthy controls. Fasting blood samples of all the subjects were collected and analysed for serum fasting insulin and serum fasting glucose levels. Homeostatic model assessment-Insulin resistance was calculated SPSS 11 was used for statistical analysis. Of the 30 subjects, 20(66.6%) were cases, while 10(33.3%) were controls. Serum fasting glucose mean level in cases was 89.55±9.53 compared to 84.40±9.80 in the controls (p=0.188). The mean serum fasting insulin in controls was 7.52±3.23 and 6.79±3.30 in cases (p=0.567). Homeostatic model assessment-Insulin resistance level in controls was 1.60±0.76 and In the cases it was 1.49±0.74 (p=0.695). Peripheral insulin resistance and development of type 2 diabetes as a complication of hepatitis C virus infection was not likely at least within the first five years of infection.

    Higher self-control in children and adolescents is associated with a range of positive outcomes in adulthood. However, little is known about the naturalistic development of self-control during early adolescence and the factors that affect this. We examined the role of puberty and parenting style as theoretically important influences on stability and change in self-control. A longitudinal (3 waves), multiple-informant dataset of children entering early adolescence (M = 11 years) was used to explore longitudinal change in self-control using latent growth curve modelling. Children's self-control declined during the one-year study period and declines were associated with children's behavioural and social functioning. Associations with self-control were found for pubertal status and parental warmth and hostility, but not for parental discipline. The findings suggest that during early adolescence, when children make the transition to secondary school, self-control declines. This is particularly the case for those experiencing puberty earlier than their peers. Parent warmth influences the trajectory of self-control during this period.

    There is no data available on the long-term outcomes of a rooted, platform-switched, microthreaded implant with a sandblasted, large-grid, and acid-etched surface. This prospective, longitudinal study evaluated the clinical and radiographic outcomes of rooted, platform-switched, microthreaded and sandblasted, large-grid, and acid-etched (SLA) surface implants for 5 years. Sixty implants were placed in sixty patients with partially edentulous maxillae or mandibles. The permanent prostheses were inserted 2-4 months after implant placement. Clinical and radiographic examinations were performed at follow-up visits scheduled postoperation, prosthesis installation, 1 year, and 5 years after surgery, to assess implant survival and success rates, biological and mechanical complications, and marginal bone loss. After 5 years' follow-up, four patients withdrawn from the study, and 56 implants achieved a 100% survival rate and 98.2% success rate. Three prosthetic complications occurred, resulting in a success rate for prostheses of 94.6%. The incidence of peri-implant mucositis was 9.1% and no peri-implantitis was diagnosed. The average marginal bone loss at the mesial aspect was 0.46 ± 0.27 mm after 1 year and 0.48 ± 0.27 mm after 5 years. The average marginal bone loss at the distal aspect was 0.46 ± 0.32 mm after 1 year and 0.50 ± 0.35 mm after 5 years. After 5 years of loading, the rooted, platform-switched, microthreaded, and SLA surface implants showed high survival and success rates, steady crestal bone levels, and excellent long-term clinical outcomes in the soft tissue. Overloading may be related to the marginal bone loss around implants, but the surgical protocol, different sites, and jaw position did not correlate with crestal bone loss. © 2017 Wiley Periodicals, Inc.

    Numerous studies have identified the effects of prematurity on the neonate\\'s physical health, however few studies have explored the effects of prematurity on both the physical and mental health of the child as they develop. Secondary analysis of data from the Millennium Cohort Study, a longitudinal study of infants (n = 18 818, born 2000-2002 in the United Kingdom) was performed. Effects of gestational age at birth on health outcomes at 5 years were measured using parental rating of their children\\'s general health and severity of behavior problems. The association between parent\\'s general health ratings and behavior problem ratings was low: 86% of those reporting serious behavior problems (5% of the sample, n = 764) rated their child as being in excellent, very good, or good health. Still, a gradient of increasing risk of poorer outcome with decreasing gestational age was observed for a composite health measure (poor\\/fair health and\\/or serious behavior problems), suggesting an association with prematurity for this composite assessment of health status. The greatest contribution to the childhood composite health measure at 5 years was for children born at 32-36 weeks gestation: population attributable fractions for having poor outcomes was 3.4% (Bonferroni-adjusted 95% confidence interval 1.1%-6.2%), compared to 1% (0.2-2.3) for birth at less than 32 weeks. Results suggest that preterm children, by school entry, are not only at high risk of physical health problems, but also of behavioral health problems. The recognition of, and response to comprehensive health and well-being outcomes related to prematurity are important in order to correctly plan and deliver adequate paediatric health services and policies.

    Research has demonstrated poor agreement between clinician-assigned personality disorder (PD) diagnoses and those generated by self-report questionnaires and semistructured diagnostic interviews. No research has compared prospectively the predictive validity of these methods. We investigated the convergence of these 3 diagnostic methods and tested their relative and incremental validity in predicting independent, multimethod assessments of psychosocial functioning performed prospectively over 5 years. Participants were 320 patients in the Collaborative Longitudinal Personality Disorders Study diagnosed with PDs by therapist, self-report, and semistructured interview at baseline. We examined the relative incremental validity of therapists' naturalistic ratings relative to these other diagnostic methods for predicting psychosocial functioning at 5-year follow-up. Hierarchical linear regression analyses revealed that both the self-report questionnaire and semistructured interview PD diagnoses had significant incremental predictive validity over the PD diagnoses assigned by a treating clinician. Although, in some cases, the clinicians' ratings for individual PDs did have validity for predicting subsequent functioning, they did not generally provide incremental prediction beyond the other methods. These findings remained robust in a series of analyses restricted to a subsample of therapist ratings based on clinical contact of 1 year or greater. These results from a large clinical sample echo previous research documenting limited agreement between clinicians' naturalistic PD diagnoses and those from self-report and semistructured interview methods. They extend prior work by providing the first evidence about the relative predictive validity of these different methods. Our findings challenge the validity of naturalistic PD diagnoses and suggest the use of structured diagnostic instruments. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    To provide a 5-year longitudinal assessment of risk of acquiring disease from Sierra Nevada Wilderness area lakes and streams. This study examines the relative risk factors for harmful water microorganisms, using coliforms as an indicator. Streams and lakes in the backcountry of Yosemite and Kings Canyon National Parks and neighboring wilderness areas were selected and water was analyzed each year over a 5-year period. A total of 364 samples from lakes or streams were chosen to statistically differentiate the risk categories based on land usage, as follows: 1) areas rarely visited by humans (Wild), 2) human day-use-only areas (Day Hike), 3) areas used by backpackers with overnight camping allowed (Backpack), 4) areas primarily impacted by horses or pack animals (Pack Animal), and 5) cattle and sheep grazing tracts (Cattle). Water was collected in sterile test tubes and Millipore coliform samplers. Water was analyzed at the university microbiology lab, where bacteria were harvested and then subjected to analysis using standardized techniques. Statistical analysis to compare site categories was performed utilizing Fisher exact test and analysis of variance. A total of 364 sampling sites were analyzed. Coliforms were found in 9% (4/47) of Wild site samples, 12% (5/42) of Day Hike site samples, and 18% (20/111) of Backpacker site samples. In contrast, 63% (70/111) of Pack Animal site samples yielded coliforms, and 96% (51/53) of samples from the Cattle areas grew coliforms. Differences between Backpacker vs Cattle or Pack Animal areas were significant at P

    Choline is an essential nutrient that is found in many food sources and plays a critical role in the development of the central nervous system. Animal studies have shown that choline status pre- and postnatally can have long-lasting effects on attention and memory; however, effects in human subjects have not been well studied. The aim of the present study was to examine the association between plasma concentrations of free choline and its related metabolites in children and their neurodevelopment in the Seychelles Child Development Nutrition Study, an ongoing longitudinal study assessing the development of children born to mothers with high fish consumption during pregnancy. Plasma concentrations of free choline, betaine, dimethylglycine (DMG), methionine and homocysteine and specific measures of neurodevelopment were measured in 210 children aged 5 years. The children’s plasma free choline concentration (9·17 (sd 2·09) µmol/l) was moderately, but significantly, correlated with betaine (r 0·24; P=0·0006), DMG (r 0·15; P=0·03), methionine (r 0·24; P=0·0005) and homocysteine (r 0·19; P=0·006) concentrations. Adjusted multiple linear regression revealed that betaine concentrations were positively associated with Preschool Language Scale – total language scores (β = 0·066; P=0·04), but no other associations were evident. We found no indication that free choline concentration or its metabolites, within the normal physiological range, are associated with neurodevelopmental outcomes in children at 5 years of age. As there is considerable animal evidence suggesting that choline status during development is associated with cognitive outcome, the issue deserves further study in other cohorts. PMID:23298754

    The present study aimed to determine how repair technique influenced structural and clinical outcomes at 5 years post-surgery. Three cohorts of patients had repair of a symptomatic rotator cuff tear using (i) an open double-row mattress repair technique (n = 25); (ii) arthroscopic single-row simple suture knotted technique (n = 25); or (iii) arthroscopic single-row inverted mattress knotless technique (n = 36) by one surgeon. Standardized patient- and examiner-determined outcomes were obtained pre-operatively and postoperatively with a validated protocol, ultrasound were also performed at the same time. Retear occurred more often after open repair (48%) at 5 years than after arthroscopic knotted (33%) and arthroscopic knotless (26%) repair. Retear was associated with increasing age, pre-operative tear size and weaker pre-operative and 5 years postoperative cuff strength. Between 2 years and 5 years, the open repair group experienced an increase in the frequency of pain during activity, as well as in the difficulty experienced and the severity of pain during overhead activities (p arthroscopic knotless repair group. At 5-year follow-up, arthroscopic rotator cuff repair techniques resulted in fewer retears and better outcomes compared to an open double-row technique.

    Triazolam has shown promise as a sedative agent for use in pediatric dentistry. However, the efficacy of triazolam has not been previously examined in a placebo-controlled study. The present clinical trial used a two-group, randomized, double-blind study design to compare the efficacy of oral triazolam with that of a placebo. The primary hypothesis tested was that triazolam would reduce negative behaviors of pediatric dental patients compared with a placebo. A secondary hypothesis was that triazolam would increase the efficiency of dental treatment by reducing the need for time-consuming behavior management by the pediatric dentist. The subjects were 54 3- to 5-year-old children, randomly assigned to the drug and placebo groups. The active drug, 0.03 mg/kg triazolam (Halcion), or lactose placebo was given orally 30 min before dental treatment. Behavior management techniques commonly used in pediatric dentistry were used during dental treatment. A single pediatric dentist provided all of the dental treatment. The procedure included an inferior block anesthesia and careful attention to anesthesia effectiveness. All sessions were video-taped and the tapes coded for child and dentist behaviors by an independent observer. There were no statistically significant differences between the groups with respect to completion of dental treatment. There were no significant differences found in either the total time or the percent of time that the subjects exhibited disruptive movements, verbal or non-verbal distress. The total use of time in the dental chair was slightly higher in the placebo than in the drug group due to more time spent preparing the child. Contrary to preliminary reports in the literature, this investigation found little or no improvement in child behavior when triazolam was used as a sedative compared with a placebo. However, triazolam did shorten the length of dental treatment, primarily by reducing dentist time in preparing the child for the dental

    UK prescribing legislation changes made in 2006 and 2012 enabled appropriately qualified nurses to prescribe any licensed medication, and all controlled drugs in schedule 2-5 of the Misuse of Drugs Regulations 2001, for any medical condition within their clinical competence. Critical Care Outreach nurses who are independent nurse prescribers are ideally placed to ensure that acutely ill patients receive treatment without delay. The perceived challenge was how Critical Care Outreach nurses would be able to safely prescribe for a diverse patient group. This study informs this developing area of nurse prescribing in critical care practice. The aims of the audit were to: identify which medications were prescribed; develop a critical care outreach formulary; identify the frequency, timing and number of prescribing decisions being made; identify if prescribing practice changed over the years and provide information for our continuing professional development. This article reports on data collected from a 5-year retrospective audit; of prescribing activity undertaken by nine independent nurse prescribers working in a 24/7 Critical Care Outreach team of a 600-bedded district general hospital in the UK. In total, 8216 medication items were prescribed, with an average of 2·6 prescribed per shift. The most commonly prescribed items were intravenous fluids and analgesia, which were mostly prescribed at night and weekends. The audit has shown that Critical Care Outreach nurse prescribing is feasible in a whole hospital patient population. The majority of prescribing occurred after 16:00 and at night. Further research would be beneficial, particularly looking at patient outcomes following reviews from prescribing critical care outreach nurses. The audit is one of the only long-term studies that describes prescribing practice in Critical Care Outreach teams in the UK. © 2017 British Association of Critical Care Nurses.

    Post-operative delirium is associated with increased short term morbidity and mortality. Limited data exists on long term outcomes for older adults with postoperative delirium. We hypothesize that postoperative delirium is associated with increased 5-year mortality. Patients ≥50 years undergoing elective operations with planned intensive care unit (ICU) admissions were prospectively enrolled. The Confusion Assessment Method ICU (CAM-ICU) was used to diagnose delirium. The primary outcome variable was 5-year mortality. 172 patients were enrolled with an average age of 64 years. The overall incidence of delirium was 44% (75/172). At 5-years post-operatively, mortality was higher (59%, 41/70) in patients with delirium compared to patients without delirium (13%, 12/94, p delirium were 7.35 fold greater (95% CI: 1.49-36.18).

     Universal 2-dose hepatitis A virus (HAV) vaccination of toddlers effectively controls hepatitis A. High vaccine costs, however, impede implementation in endemic countries. To test single-dose vaccination as a possible alternative, we initiated an observational, longitudinal study in Nicaragua, to assess protective effectiveness and-through challenge vaccination-humoral immune memory response.  After a 2003 serosurvey, 130 originally seronegative children received one dose of virosomal HAV vaccine in 2005, followed by yearly serological and clinical assessments until 2012. After 7.5 years, a vaccine booster was administered. Concurrent antibody screening of patients presenting with hepatitis symptoms documented persistent HAV circulation in the communities studied.  Between serosurvey and vaccination, 25 children contracted hepatitis A subclinically (>8000 mIU/mL anti-HAV). In the remaining 105 children, immunization resulted in anti-HAV levels of 17-572 mIU/mL. Based on the ≥15% annual infection risk, an estimated 60% of children were exposed to HAV encounters during follow-up. No child presented with hepatitis symptoms. Serological breakthrough infection (7106 mIU/mL) was documented in 1 child, representing an estimated protective effectiveness of 98.3% (95% confidence interval, 87.9-99.8). Boosting elicited an average 29.7-fold increase of anti-HAV levels.  In children living in hyperendemic settings, a single dose of virosomal HAV vaccine is sufficient to activate immune memory and may provide long-term protection. © The Author 2016.

    To describe our experience treating a cohort of unilateral aphakic infants with contact lenses in the Infant Aphakia Treatment Study (IATS). Fifty-seven of the 114 infants in the IATS were randomized to contact lens wear; all were followed until age 5 years, although a few had lapses in care. An examination under anesthesia, including keratometry, was performed at the time of enrollment and at approximately 1 year of age; keratometry was performed again at 5 years of age. A traveling examiner assessed visual acuity at approximately 1 year of age and again at 4.5 years of age. Twenty-four treated eyes (46%) wore silicone elastomer (SE) contact lenses, 11 eyes (19%) rigid gas permeable (GP) contact lenses and 17 eyes (29%) wore both lens types at various points of time. Median logMAR visual acuity was +0.70 (interquartile range (IQR), +0.30 to 1.20) in the SE group and 2.03 (IQR, +0.20 to 2.28) in the GP group at age 4.5 years. The mean (±SD) keratometric power of the treated eyes was 46.3±2.8 diopter (D) at baseline, 44.6±2.3 D at 1 year of age, and 44.3±1.7 D at 5 years of age. Keratometric astigmatism of treated eyes was 1.98±1.37 D at baseline, 1.62±0.98 D at 1 year of age, and 2.00±1.00 D at 5 years of age. Thirteen contact lens-related adverse events occurred among 7 patients after age 1 year. A cohort of infants with unilateral aphakia successfully wore contact lenses with relatively few adverse events.

    Adolescents with asthma experience more psychosocial and physiological problems compared to their healthy peers. Physical activity (PA) might decrease these problems. This study was the first observational longitudinal study to examine whether habitual PA could predict changes in psychosocial outcomes (i.e., symptoms of anxiety and depression, quality of life [QOL] and stress) and asthma control over time in adolescents with asthma and whether gender moderated these relationships. Adolescents with asthma (N = 253; aged 10-14 years at baseline) were visited at home in the spring/summer of 2012 and 2013. They completed questionnaires assessing their habitual PA, symptoms of anxiety and depression, QOL, perceived stress and asthma control. Path analyses using Mplus were conducted to examine longitudinal relationships among habitual PA, psychosocial outcomes and asthma control (controlled for body mass index, age and gender). Using multi-group analyses, we examined whether gender moderated these relationships. Path analyses in the total group showed that habitual PA did not predict changes in psychosocial outcomes or asthma control over time. Multi-group analyses showed that gender moderated the relation of habitual PA with anxiety and depression. Habitual PA only significantly predicted a decrease in anxiety and depression over time for girls but not for boys. Increasing habitual PA in girls with asthma might decrease their symptoms of anxiety and depression.

    Although homelessness is inherently associated with social exclusion, homeless individuals are rarely included in conventional studies on social exclusion. Use of longitudinal survey data from a cohort study on homeless people in four major Dutch cities ( n  = 378) allowed to examine: changes in indicators of social exclusion among homeless people over a 2.5-year period after reporting to the social relief system, and associations between changes in indicators of social exclusion and changes in psychological distress. Multinomial logistic regression analysis was applied to investigate the associations between changes in indicators of social exclusion and changes in psychological distress. Improvements were found in various indicators of social exclusion, whereas financial debts showed no significant improvement. Changes in unmet care needs, health insurance, social support from family and relatedness to others were related to changes in psychological distress. This study demonstrated improvements in various indicators of social exclusion among homeless people over a period of 2.5 years, and sheds light on the concept of social exclusion in relation to homelessness.

    previous research has shown that tendencies to tenaciously pursue goals (TGP) and flexibly adapt goals (FGA) relate to well-being of older people. this study aimed to identify subpopulations of elderly people with different coping profiles, describe change in participants' profiles over time and determine the influence of coping profiles on well-being over a 5-year period. latent profile transition analysis (LPTA) was used in a three-wave longitudinal data collection measuring flexibility, tenacity, depression, self-rated health and life satisfaction among an elderly population over 65 years old. three coping profiles were identified. Profile 1 was characterised by participants with high flexibility and tenacity scores, Profile 2 with moderate flexibility and low tenacity scores and Profile 3 with low flexibility and moderate tenacity scores. Results indicate stability of these profiles over time, with Profile 1 being the most adaptive in terms of ageing well. high flexibility and tenacity in older people is a stable coping profile that is associated with successful ageing. © The Author 2016.

    This study examined the associations of insomnia symptoms with subsequent psychotropic medication, reflecting mental health. Postal baseline surveys among 40- to 60-year-old employees of the city of Helsinki, Finland, were collected in 2000-2002 (N = 6,227, response rate 67%, 78% women) and longitudinally linked with national register data on prescribed reimbursed medication. Insomnia symptoms at baseline comprised difficulties in initiating and maintaining sleep, and non-restorative sleep. All purchased psychotropic medication 5-7 years prior to and 5 years after baseline was included. Outcomes were any psychotropic medication; antidepressants; and anxiolytics, hypnotics, and sedatives. Covariates included socio-demographic and work-related factors, health behaviors, lifetime mental disorders, and prior psychotropic medication. Logistic regression analysis was used to calculate odds ratios (OR) and their 95% confidence intervals (CI). Insomnia symptoms were associated with higher frequency of subsequent psychotropic medication prescriptions. The associations were strongest for frequent insomnia symptoms (women OR 3.55, 95% CI 2.64-4.77; men OR 4.64, 95% CI 2.49-8.66, adjusted for age and prior medication), but also rare and occasional symptoms were associated with psychotropic medication. Further adjustments had negligible effects. Insomnia symptoms were associated with prescribed psychotropic medication during follow-up in a dose-response manner. Attention should be given to the prevention of insomnia symptoms to curb subsequent mental problems.

  12. Longitudinal Predictors of Institutionalization in Old Age.

    Directory of Open Access Journals (Sweden)

    André Hajek

    Full Text Available To investigate time-dependent predictors of institutionalization in old age using a longitudinal approach.In a representative survey of the German general population aged 75 years and older predictors of institutionalization were observed every 1.5 years over six waves. Conditional fixed-effects logistic regressions (with 201 individuals and 960 observations were performed to estimate the effects of marital status, depression, dementia, and physical impairments (mobility, hearing and visual impairments on the risk of admission to old-age home or nursing home. By exploiting the longitudinal data structure using panel econometric models, we were able to control for unobserved heterogeneity such as genetic predisposition and personality traits.The probability of institutionalization increased significantly with occurrence of widowhood, depression, dementia, as well as walking and hearing impairments. In particular, the occurrence of widowhood (OR = 78.3, dementia (OR = 154.1 and substantial mobility impairment (OR = 36.7 were strongly associated with institutionalization.Findings underline the strong influence of loss of spouse as well as dementia on institutionalization. This is relevant as the number of old people (a living alone and (b suffering from dementia is expected to increase rapidly in the next decades. Consequently, it is supposed that the demand for institutionalization among the elderly will increase considerably. Practitioners as well as policy makers should be aware of these upcoming challenges.

  13. Effects of a Randomized Reading Intervention Study Aimed at 9-Year-Olds: A 5-Year Follow-up.

    The present paper reports on a 5-year follow-up of a randomized reading intervention in grade 3 in Sweden. An intervention group (n = 57) received daily training for 12 weeks in phoneme/grapheme mapping, reading comprehension and reading speed, whereas a control group (n = 55) participated in ordinary classroom activities. The main aim was to investigate if there were remaining effects of the intervention on reading-related skills. Previous analyses showed that the intervention group performed significantly better than the control group on spelling, reading speed, reading comprehension and phoneme awareness at the immediate post-test with sustained effects 1 year later. Results from the 5-year follow-up show that the only significant difference between the intervention (n = 47) and the control group (n = 37) was on word decoding. There was also a significant interaction effect of group assignment and initial word decoding, in the way that the lowest-performing students benefitted the most from the intervention. Another aim was to examine if the children identified in a screening (n = 2212) as poor readers in grade 2 still performed worse than typical readers. The analyses showed that the typically developing students (n = 66) outperformed the students identified as poor readers in grade 2 on working memory, spelling, reading comprehension and word decoding.
