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

Intelligence and obesity: which way does the causal direction go?

PubMed

Kanazawa, Satoshi

2014-10-01

The negative association between intelligence and obesity has been well established, but the direction of causality is unclear. The present review surveys the recent studies on the topic with both cross-sectional and longitudinal data in an attempt to establish causality. Most studies in the area employ cross-sectional data and conclude (without empirical justification) that obesity causes intellectual impairment. The few studies that employ prospectively longitudinal data, however, uniformly conclude that lower intelligence leads to BMI gains and obesity. A close examination of three such studies, from three different nations (Sweden, New Zealand, and the UK), leaves little doubt that the causality runs from low intelligence to obesity. The conclusion in previous studies that obesity impairs cognitive function stems from improper interpretation of a negative association between intelligence and obesity from cross-sectional studies. Results from the analyses of high-quality, population-based, prospectively longitudinal data firmly establish that low intelligence increases the chances of obesity.

With increasing age, physical capacity decreases, while the need and time for recovery increases. At the same time, the demands of work usually do not change with age. In the near future, an aging and physically changing workforce risks reduced work ability. Therefore, the impact of different factors, such as physical activity, on work ability is of interest. Thus, the aim of this study was to evaluate the association between physical activity and work ability using both cross sectional and prospective analyses. This study was based on an extensive questionnaire survey. The number of participants included in the analysis at baseline in 2004 was 2.783, of whom 2.597 were also included in the follow-up in 2006. The primary outcome measure was the Work Ability Index (WAI), and the level of physical activity was measured using a single-item question. In the cross-sectional analysis we calculated the level of physical activity and the prevalence of poor or moderate work ability as reported by the participants. In the prospective analysis we calculated different levels of physical activity and the prevalence of positive changes in WAI-category from baseline to follow-up. In both the cross sectional and the prospective analyses the prevalence ratio was calculated using Generalized Linear Models. The cross-sectional analysis showed that with an increased level of physical activity, the reporting of poor or moderate work ability decreased. In the prospective analysis, participants reporting a higher level of physical activity were more likely to have made an improvement in WAI from 2004 to 2006. The level of physical activity seems to be related to work ability. Assessment of physical activity may also be useful as a predictive tool, potentially making it possible to prevent poor work ability and improve future work ability. For employers, the main implications of this study are the importance of promoting and facilitating the employees' engagement in physical activity, and the importance of the employees' maintaining a physically active lifestyle.

Rank-based testing of equal survivorship based on cross-sectional survival data with or without prospective follow-up.

Existing linear rank statistics cannot be applied to cross-sectional survival data without follow-up since all subjects are essentially censored. However, partial survival information are available from backward recurrence times and are frequently collected from health surveys without prospective follow-up. Under length-biased sampling, a class of linear rank statistics is proposed based only on backward recurrence times without any prospective follow-up. When follow-up data are available, the proposed rank statistic and a conventional rank statistic that utilizes follow-up information from the same sample are shown to be asymptotically independent. We discuss four ways to combine these two statistics when follow-up is present. Simulations show that all combined statistics have substantially improved power compared with conventional rank statistics, and a Mantel-Haenszel test performed the best among the proposal statistics. The method is applied to a cross-sectional health survey without follow-up and a study of Alzheimer's disease with prospective follow-up. © The Author 2015. Published by Oxford University Press.

Psychosocial work factors and sleep problems: findings from the French national SIP survey.

PubMed

Chazelle, Emilie; Chastang, Jean-François; Niedhammer, Isabelle

2016-04-01

This study aimed at exploring the cross-sectional and prospective associations between psychosocial work factors and sleep problems. The study population consisted of a national representative sample of the French working population (SIP survey). The sample sizes were 7506 and 3555 for the cross-sectional and prospective analyses. Sleep problems were defined by either sleep disturbances or insufficient sleep duration at least several times a week. Psychosocial work factors included classical (job strain model factors) and emergent factors (recognition, insecurity, role/ethical conflict, emotional demands, work-life imbalance, etc.). Occupational factors related to working time/hours and physical work environment were also included as well as covariates related to factors outside work. Statistical analyses were performed using weighted Poisson regression analysis. In the cross-sectional analyses, psychological demands, low social support, low recognition, emotional demands, perception of danger, work-life imbalance and night work were found to be associated with sleep problems. In the prospective analyses, psychological demands and night work were predictive of sleep problems. Using a less conservative method, more factors were found to be associated with sleep problems. Dose-response associations were observed, showing that the more frequent the exposure to these factors, the higher the risk of sleep problems. No effect of repeated exposure was found on sleep problems. Classical and emergent psychosocial work factors were associated with sleep problems. More prospective studies and prevention policies may be needed.

OBJECTIVE To conduct a systematic review of cross-sectional and prospective human studies evaluating metabolite markers identified using high-throughput metabolomics techniques on prediabetes and type 2 diabetes. RESEARCH DESIGN AND METHODS We searched MEDLINE and EMBASE databases through August 2015. We conducted a qualitative review of cross-sectional and prospective studies. Additionally, meta-analyses of metabolite markers, with data estimates from at least three prospective studies, and type 2 diabetes risk were conducted, and multivariable-adjusted relative risks of type 2 diabetes were calculated per study-specific SD difference in a given metabolite. RESULTS We identified 27 cross-sectional and 19 prospective publications reporting associations of metabolites and prediabetes and/or type 2 diabetes. Carbohydrate (glucose and fructose), lipid (phospholipids, sphingomyelins, and triglycerides), and amino acid (branched-chain amino acids, aromatic amino acids, glycine, and glutamine) metabolites were higher in individuals with type 2 diabetes compared with control subjects. Prospective studies provided evidence that blood concentrations of several metabolites, including hexoses, branched-chain amino acids, aromatic amino acids, phospholipids, and triglycerides, were associated with the incidence of prediabetes and type 2 diabetes. We meta-analyzed results from eight prospective studies that reported risk estimates for metabolites and type 2 diabetes, including 8,000 individuals of whom 1,940 had type 2 diabetes. We found 36% higher risk of type 2 diabetes per study-specific SD difference for isoleucine (pooled relative risk 1.36 [1.24–1.48]; I2 = 9.5%), 36% for leucine (1.36 [1.17–1.58]; I2 = 37.4%), 35% for valine (1.35 [1.19–1.53]; I2 = 45.8%), 36% for tyrosine (1.36 [1.19–1.55]; I2 = 51.6%), and 26% for phenylalanine (1.26 [1.10–1.44]; I2 = 56%). Glycine and glutamine were inversely associated with type 2 diabetes risk (0.89 [0.81–0.96] and 0.85 [0.82–0.89], respectively; both I2 = 0.0%). CONCLUSIONS In studies using high-throughput metabolomics, several blood amino acids appear to be consistently associated with the risk of developing type 2 diabetes. PMID:27208380

Most studies examining factors associated with colorectal cancer (CRC) screening (CRCS) are cross-sectional and thus temporal relationships cannot be determined. Furthermore, less attention has been paid to psychosocial predictors of CRCS. We examined both cross-sectional correlates of prior CRCS and predictors of prospective CRCS initiation and maintenance during The Next Step Trial, a 2-year worksite behavioral intervention to promote regular CRCS and dietary change. The sample included 2,693 White male automotive workers at increased occupational risk for, but no history of, CRC who completed a baseline survey. Stratified analyses were conducted for three dependent variables (prior CRCS, CRCS initiation, and CRCS maintenance). We also assessed prior CRCS as a moderator in prospective analyses. Multivariable logistic regression analyses with generalized linear mixed models were used to adjust for cluster sampling. Except for education, cross-sectional correlates of prior CRCS including older age, family history of CRC or polyps, personal history of polyps, self-efficacy, family support, and intention were also significant prospective predictors of increased CRCS during the trial. Despite differences in the patterns of association for CRCS initiation and maintenance in stratified analyses, the only associations with prospective CRCS that were significantly moderated by prior CRCS were family history and CRCS availability. Correlates of prior CRCS that also were prospective predictors of CRCS may be suitable targets for intervention. Additionally, intervention messages addressing psychosocial constructs may be relevant for both CRCS initiation and maintenance. However, studies with more diverse samples are needed to replicate the results reported here.

Emerging evidence suggests that bilirubin levels might be associated with the metabolic syndrome (MetS) and type 2 diabetes (T2D), although the nature of the association remains unclear. This systematic review and meta-analysis investigated the relationship between total plasma bilirubin and the risk of MetS and T2D. Relevant studies were identified using five databases (Embase, Medline [Ovid], Web of Science, PubMed, Cochrane Central and Google Scholar), with the last search done on 21 October 2015. Study references were checked and authors contacted to identify additional studies. Randomized controlled trials, and cohort, case-control and cross-sectional studies of adults examining the association between blood bilirubin levels and MetS and T2D were included, irrespective of language and date of publication. Abstract and full-text selection was done by two independent reviewers, with a third reviewer available in case of disagreement. Data were extracted by two independent reviewers using a predesigned data collection form. MetS and T2D. Summary estimates were obtained by random-effects meta-analysis. Of the 2313 searched references, 16 observational studies (11 cross-sectional, two prospective, one that was both cross-sectional and prospective, two retrospective and one national survey) met our inclusion criteria. Overall, data were available for 175,911 non-overlapping participants, including 7414 MetS cases and 9406 T2D cases. In the meta-analysis of seven cross-sectional studies, the pooled odds ratio (95% confidence interval) for MetS in a comparison of extreme tertiles of serum bilirubin levels was 0.70 (95% CI: 0.62, 0.78), whereas no significant association was found for the pooled estimated relative risk between two prospective studies (0.57, 95% CI: 0.11, 2.94). The corresponding estimate was 0.77 (95% CI: 0.67, 0.87) for T2D from four cross-sectional studies. The available evidence, mainly from cross-sectional studies, supports an inverse association of bilirubin levels with adverse metabolic outcomes. Large-scale prospective studies are now needed to establish whether bilirubin levels may be useful in the prevention of MetS and T2D. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Endocrine-disrupting chemicals and risk of diabetes: an evidence-based review.

PubMed

Lind, P Monica; Lind, Lars

2018-05-09

The purpose of this study was to review the epidemiological and experimental evidence linking background exposure to a selection of environmental endocrine-disrupting chemicals (EDCs) with diabetes and impaired glucose metabolism. The review summarises the literature on both cross-sectional and prospective studies in humans, as well as experimental in vivo and in vitro studies. The findings were subjected to evidence grading according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) classification. We found >40 cross-sectional and seven prospective studies regarding EDCs and risk of diabetes. Taken together, there is moderate evidence for a relationship between exposure to dichlorodiphenyldichloroethylene (p,p'-DDE), a metabolite of the pesticide dichlorodiphenyltrichloroethane, and diabetes development. Regarding polychlorinated biphenyls (PCBs), it is likely that the rodent models used are not appropriate, and therefore the evidence is poorer than for p,p'-DDE. For other EDCs, such as bisphenol A, phthalates and perfluorinated chemicals, the evidence is scarce, since very few prospective studies exist. Brominated flame retardants do not seem to be associated with a disturbed glucose tolerance. Thus, evidence is accumulating that EDCs might be involved in diabetes development. Best evidence exists for p,p'-DDE. For other chemicals, both prospective studies and supporting animal data are still lacking.

Ferrara, A; Barrett-Connor, E; Shan, J

1997-07-01

The purpose of the present study was to study the effects of age, weight change, and covariates on lipid and lipoprotein levels cross-sectionally and prospectively in an elderly population. A community-based sample of 1041 men and 1303 women aged 50 to 93 years was studied cross-sectionally in 1984 to 1987, with follow-up of 372 men and 545 women 8 years later. In the cross-sectional study, levels of total cholesterol (TC) and LDL cholesterol (LDL-C) decreased and levels of HDL cholesterol (HDLC) increased with age in men (all P < .001) but not in women. In the prospective study, TC, LDL-C, and HDL-C levels all decreased in both men and women, in all age groups (50 to 64 years, 65 to 74 years, and > or = 75 years) and in all weight change groups (> 2.5-kg loss, change within 2.5 kg, and > 2.5-kg gain) and in all waist girth change groups, for an overall decrement of approximately 1% per year. In multiple linear regression models, change in weight was the most important independent and consistent predictor of changes in TC, LDL-C, and HDL-C. Similar results were obtained in analyses excluding subjects taking lipid-lowering drugs or estrogen and in analyses adjusted for changes in cigarette smoking, alcohol intake, physical activity, medication use, and incident myocardial infarction, cancer, or diabetes. Cross-sectional decrements in TC and LDL-C with age in men are not explained by survivor bias because they are also observed prospectively. Although weight change was the most important explanatory variable, TC, LDL-C, and HDL-C levels also decreased in those who lost or gained weight. Age was not an independent predictor of change. Other prospective studies are recommended to better define the causes and consequences of cholesterol and lipoprotein changes in old age.

As histopathologic assessment is subject to sampling error, some institutions 'preorder' deeper sections on some or all cases (hereafter referred to as prospective deeper sections), while others order additional sections only when needed (hereafter referred to as retrospective deeper sections). We investigated how often additional sections changed a diagnosis and/or clinical management. Given the recent decrease in reimbursement for CPT-code 88305, we also considered the financial implications of ordering additional sections. Cases (n = 204) were assigned a preliminary diagnosis, based on review of the initial slide, and a final diagnosis, after reviewing additional sections. Cases with discordant diagnoses were assessed by two dermatologists, who indicated whether the change in diagnosis altered clinical management. Expenses were estimated for three scenarios: (a) no additional sections, (b) prospective deeper sections and (c) retrospective deeper sections. Diagnoses were modified in 9% of cases, which changed clinical management in 56% of these cases. Lesions obtained by punch-biopsy and inflammatory lesions were disproportionately overrepresented amongst cases with changed diagnoses (p < 0.001, p = 0.12, respectively). The cost of prospective deeper sections and retrospective deeper sections represented a 56% and 115% increase over base costs, respectively. Labor costs, particularly the cost of dermatopathologist evaluation, were the most significant cost-drivers. While additional sections improve diagnostic accuracy, they delay turn-around-time and increase expenditures. In our practice, prospective deeper sections are cost effective, however, this may vary by institution. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

2016-04-01

This prospective cohort study examined previously underexplored relations between psychological/social work factors and troubled sleep in order to provide practical information about specific, modifiable factors at work. A comprehensive evaluation of a range of psychological/social work factors was obtained by several designs; i.e., cross-sectional analyses at baseline and follow-up, prospective analyses with baseline predictors (T1), prospective analyses with average exposure across waves as predictor ([T1 + T2] / 2), and prospective analyses with change in exposure from baseline to follow-up as predictor. Participants consisted of a sample of Norwegian employees from a broad spectrum of occupations, who completed a questionnaire at two points in time, approximately two years apart. Cross-sectional analyses at T1 comprised 7,459 participants, cross-sectional analyses at T2 included 6,688 participants. Prospective analyses comprised a sample 5,070 of participants who responded at both T1 and T2. Univariable and multivariable ordinal logistic regressions were performed. Thirteen psychological/social work factors and two aspects of troubled sleep, namely difficulties initiating sleep and disturbed sleep, were studied. Ordinal logistic regressions revealed statistically significant associations for all psychological and social work factors in at least one of the analyses. Psychological and social work factors predicted sleep problems in the short term as well as the long term. All work factors investigated showed statistically significant associations with both sleep items, however quantitative job demands, decision control, role conflict, and support from superior were the most robust predictors and may therefore be suitable targets of interventions aimed at improving employee sleep. © 2016 Associated Professional Sleep Societies, LLC.

It has been speculated that the immediate decrease in body fat following liposuction may affect body composition by feedback mechanisms of body fat regain. Physical activity has both short- and long-term impacts on health. Although the lay public often associates higher levels of physical activity with body fat distribution changes, studies on the association between physical activity and body fat distribution present inconsistent results. The aim of this study was to investigate the cross-sectional and prospective associations between physical activity and body mass index following liposuction. This is a prospective, bidirectional, cross-sectional study, including 526 liposuction patients, who were followed up at a mean of 11.7 and 24.3 months after surgery. The sum of skinfolds at 11.7 months was highly correlated with skinfolds at 24.3 months (rho = 0.74, p < 0.001). More than 85 percent of participants remained in the same quintile or changed by not more than one quintile during the 13.6-month period. Tracking of physical activity was considerably lower but still significant; the correlation was 0.24 (p < 0.001), and 61.4 percent of the patients moved one or less quintiles. In fully adjusted models, no significant cross-sectional or longitudinal associations were found between physical activity and body mass index. The authors provide evidence of tracking of physical activity and particularly body mass index following liposuction. The authors' results do not support the hypothesis that physical activity and fatness are strongly related following liposuction.

Habitual Chocolate Consumption May Increase Body Weight in a Dose-Response Manner

Greenberg, James A.; Buijsse, Brian

2013-01-01

Objective Habitual chocolate intake was recently found to be associated with lower body weight in three cross-sectional epidemiological studies. Our objective was to assess whether these cross-sectional results hold up in a more rigorous prospective analysis. Methods We used data from the Atherosclerosis Risk in Communities cohort. Usual dietary intake was assessed by questionnaire at baseline (1987–98), and after six years. Participants reported usual chocolate intake as the frequency of eating a 1-oz (∼28 g) serving. Body weight and height were measured at the two visits. Missing data were replaced by multiple imputation. Linear mixed-effects models were used to evaluate cross-sectional and prospective associations between chocolate intake and adiposity. Results Data were from 15,732 and 12,830 participants at the first and second visit, respectively. More frequent chocolate consumption was associated with a significantly greater prospective weight gain over time, in a dose-response manner. For instance, compared to participants who ate a chocolate serving less often than monthly, those who ate it 1–4 times a month and at least weekly experienced an increase in Body Mass Index (kg/m2) of 0.26 (95% CI 0.08, 0.44) and 0.39 (0.23, 0.55), respectively, during the six-year study period. In cross-sectional analyses the frequency of chocolate consumption was inversely associated with body weight. This inverse association was attenuated after excluding participants with preexisting obesity-related illness. Compared to participants without such illness, those with it had higher BMI and reported less frequent chocolate intake, lower caloric intake, and diets richer in fruits and vegetables. They tended to make these dietary changes after becoming ill. Conclusions Our prospective analysis found that a chocolate habit was associated with long-term weight gain, in a dose-response manner. Our cross-sectional finding that chocolate intake was associated with lower body weight did not apply to participants without preexisting serious illness. PMID:23950919

For instance, compared to participants who ate a chocolate serving less often than monthly, those who ate it 1-4 times a month and at least weekly experienced an increase in Body Mass Index (kg/m2) of 0.26 (95% CI 0.08, 0.44) and 0.39 (0.23, 0.55), respectively, during the six-year study period. In cross-sectional analyses the frequency of chocolate consumption was inversely associated with body weight. This inverse association was attenuated after excluding participants with preexisting obesity-related illness. Compared to participants without such illness, those with it had higher BMI and reported less frequent chocolate intake, lower caloric intake, and diets richer in fruits and vegetables. They tended to make these dietary changes after becoming ill. Our prospective analysis found that a chocolate habit was associated with long-term weight gain, in a dose-response manner. Our cross-sectional finding that chocolate intake was associated with lower body weight did not apply to participants without preexisting serious illness.

Vaginal breech delivery: results of a prospective registration study

PubMed Central

2013-01-01

Background Most countries recommend planned cesarean section in breech deliveries, which is considered safer than vaginal delivery. As one of few countries in the western world Norway has continued to practice planned vaginal delivery in selected women. The aim of this study is to evaluate prospectively registered neonatal and maternal outcomes in term singleton breech deliveries in a Norwegian hospital during a ten years period. We aim to compare maternal and neonatal outcomes in term breech pregnancies subjected either to planned vaginal or elective cesarean section. Methods A prospective registration study including 568 women with term breech deliveries (>37 weeks) consecutively registered at Sorlandet Hospital Kristiansand between 2001 and 2011. Fetal and maternal outcomes were compared according to delivery method; planned vaginal delivery versus planned cesarean section. Results Of 568 women, elective cesarean section was planned in 279 (49%) cases and vaginal delivery was planned in 289 (51%) cases. Acute cesarean section was performed in 104 of the planned vaginal deliveries (36.3%). There were no neonatal deaths. Two cases of serious neonatal morbidity were reported in the planned vaginal group. One infant had seizures, brachial plexus injury, and cephalhematoma. The other infant had 5-minutes Apgar < 4. Twenty-nine in the planned vaginal group (10.0%) and eight in the planned cesarean section group (2.9%) (p < 0.001) were transferred to the neonatal intensive care unit. However, only one infant was admitted for ≥4 days. According to follow-up data (median six years) none of these infants had long-term sequelae. Regarding maternal morbidity, blood loss was the only variable that was significantly higher in the planned cesarean section group versus in the vaginal delivery group (p < 0.001). Conclusions Strict guidelines were followed in all cases. There were no neonatal deaths. Two infants had serious neonatal morbidity in the planned vaginal group without long-term sequelae.

Vleeshouwers, Jolien; Knardahl, Stein; Christensen, Jan Olav

2016-01-01

Study Objectives: This prospective cohort study examined previously underexplored relations between psychological/social work factors and troubled sleep in order to provide practical information about specific, modifiable factors at work. Methods: A comprehensive evaluation of a range of psychological/social work factors was obtained by several designs; i.e., cross-sectional analyses at baseline and follow-up, prospective analyses with baseline predictors (T1), prospective analyses with average exposure across waves as predictor ([T1 + T2] / 2), and prospective analyses with change in exposure from baseline to follow-up as predictor. Participants consisted of a sample of Norwegian employees from a broad spectrum of occupations, who completed a questionnaire at two points in time, approximately two years apart. Cross-sectional analyses at T1 comprised 7,459 participants, cross-sectional analyses at T2 included 6,688 participants. Prospective analyses comprised a sample 5,070 of participants who responded at both T1 and T2. Univariable and multivariable ordinal logistic regressions were performed. Results: Thirteen psychological/social work factors and two aspects of troubled sleep, namely difficulties initiating sleep and disturbed sleep, were studied. Ordinal logistic regressions revealed statistically significant associations for all psychological and social work factors in at least one of the analyses. Psychological and social work factors predicted sleep problems in the short term as well as the long term. Conclusions: All work factors investigated showed statistically significant associations with both sleep items, however quantitative job demands, decision control, role conflict, and support from superior were the most robust predictors and may therefore be suitable targets of interventions aimed at improving employee sleep.

2012-01-01

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

2017-05-01

This study examined the relationship between physical activity (PA) and chronic diseases in European older adults, using a prospective analysis with data from 2011 and 2013. Participants were 37,524 older adults (16,204 men) who responded to the fourth (in 2011) and fifth (in 2013) wave of SHARE project, from 13 European countries. Participants' answers to interview questions about the presence of chronic conditions and PA. The cross-sectional and prospective association between PA and the number of chronic diseases was assessed using general linear models. Among men and women, moderate or vigorous physical activity (MVPA) in 2011 was associated with fewer reported chronic diseases in 2011 and 2013. In prospective analysis, MVPA in 2011 was inversely associated with the number of chronic diseases in 2013 in the unadjusted model. In the adjusted model MVPA more than once a week remained as a significant predictor of fewer chronic diseases. PA should be prescribed to older adults in order to prevent and reduce the number of chronic diseases, and, when possible, vigorous intensity PA should be recommended.

2006-01-01

Objective Cross-sectional/retrospective data have indicated that individuals with body dysmorphic disorder (BDD) have high rates of suicidal ideation and attempts. However, no study, to the authors' knowledge, has prospectively examined suicidality in BDD. Method In the first prospective study of BDD's course, the authors examined suicidality in 185 subjects for up to 4 years. Results Suicidal ideation was reported by a mean of 57.8% of the subjects per year, and a mean of 2.6% attempted suicide per year. Two subjects (0.3% per year) completed suicide. Conclusions Individuals with BDD have high rates of suicidal ideation and attempts. The completed suicide rate is preliminary but suggests that the rate of completed suicide in BDD is markedly high.

Several studies have reported an increase in risk behaviors among adolescents after experience of parental divorce. The aim of the study was to investigate whether parental divorce is associated with risk behavior among adolescents independent of mental health problems, first when early divorce was experienced, and second after experience of late parental divorce. One prospective (n=1861) and one cross-sectional study (n=2422) were conducted using data from two Young-HUBRO surveys in Oslo, Norway. All 15/16 year-old 10(th) grade students who participated in the first survey in the school year 2000/01 were followed-up in 2004 when they were 18/19 year-olds. The follow-up rate was 68%. The prospective study investigated the influence of late parental divorce that occurred between the age of 15/16 and 18/19. In the cross-sectional study we focused on early parental divorce that occurred before the participants were 15/16 year-old. In the prospective study we could not discern a significant association between experiencing late parental divorce and an increase in risk behaviors among 18/19 year-old adolescents. In the cross-sectional study parental divorce was significantly associated with cigarette smoking and using doping agents. Parental divorce that occurs when the children of divorced parents are 15/16 year-old or younger is associated with an increase in cigarette smoking and use of doping agents. However, no evidence of significant association is found between experience of late parental divorce and risk behaviors in late adolescence.

2015-02-01

Loneliness has been linked cross-sectionally to emotional skill deficits (e.g., Zysberg, 2012), but missing from the literature is a longitudinal examination of these relationships. The present study fills that gap by examining the prospective relationships between loneliness and emotional functioning in young adolescents in England. One hundred and ninety-six adolescents aged 11-13 years (90 females) took part in the study and completed the youth version of the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT-YV) and the peer-related subscale of the Loneliness and Aloneness Scale for Children and Adolescents (LACA) at two time points, which were 10 months apart. Prospective associations were obtained for male and female adolescents separately using cross-lagged statistical techniques. Our results showed prospective links between understanding and managing emotions and loneliness for both females and males. Perceiving and using emotions were prospectively linked to loneliness in males only. Possible explanations and directions for future research are discussed.

Intense migrations from tuberculosis endemic areas to Gulf countries create special risks for people in the region. The purpose of this study was to provide data that could justify implementing universal, regular TB screening in UAE. This prospective, cross-sectional study used interferon-γ release assay (IGRA) to screen for TB among Emirati citizens between August-2016 and May-2017; expatriates were not included in this study. Participants were recruited from Emiratis attending Tawam Hospital Polyclinics for problems unrelated to TB risk assessment. IGRA was requested for all enrolled participants. A risk-assessment questionnaire was completed by all participants. In addition, a retrospective review of IGRA results (January-2011 to April-2016) was conducted to compare prevalence of positive IGRA in the 'prospective sample' with that in 'patients screened in the past'. Four hundred fifty-five participants (69% females) were enrolled in this study. Participants' age (mean±SD) was 42±16y. The majority of participants had traveled to or had helpers from TB-endemic areas. Two hundred forty (53%) participants had IGRA test. Forty-five (18.8%) participants had positive IGRA, similar to the retrospective results of 12.4% to 23.5%. The prevalence of positive-IGRA in this study is high. Copyright © 2018 The Author(s).

An evaluation is made of prospective missile applications for noncircular cross section bodies, and of recent developments in bank-to-turn missile configuration aerodynamics. The discussion encompasses cross-flow analysis techniques, as well as study results obtained for bodies with elliptical and square cross sections and with variable cross sections. Attention is given to both the performance advantages and the stability and control problems of bank-to-turn missile configurations; the aerodynamic data presented for monoplanar configurations extend to those incorporating airbreathing propulsion systems.

Prospects for Precision Neutrino Cross Section Measurements

DOE Office of Scientific and Technical Information (OSTI.GOV)

Harris, Deborah A.

2016-01-28

The need for precision cross section measurements is more urgent now than ever before, given the central role neutrino oscillation measurements play in the field of particle physics. The definition of precision is something worth considering, however. In order to build the best model for an oscillation experiment, cross section measurements should span a broad range of energies, neutrino interaction channels, and target nuclei. Precision might better be defined not in the final uncertainty associated with any one measurement but rather with the breadth of measurements that are available to constrain models. Current experience shows that models are better constrainedmore » by 10 measurements across different processes and energies with 10% uncertainties than by one measurement of one process on one nucleus with a 1% uncertainty. This article describes the current status of and future prospects for the field of precision cross section measurements considering the metric of how many processes, energies, and nuclei have been studied.« less

The gut hormone response following Roux-en-Y gastric bypass: cross-sectional and prospective study.

Bariatric surgery is the most effective treatment option for obesity, and gut hormones are implicated in the reduction of appetite and weight after Roux-en-Y gastric bypass. Although there is increasing interest in the gut hormone changes after gastric bypass, the long-term changes have not been fully elucidated. Thirty-four participants were studied cross-sectionally at four different time points, pre-operatively (n = 17) and 12 (n = 6), 18 (n = 5) and 24 months (n = 6) after laparoscopic Roux-en-Y gastric bypass. Another group of patients (n = 6) were studied prospectively (18-24 months). All participants were given a standard 400 kcal meal after a 12-h fast, and plasma levels of peptide YY (PYY) and glucagon-like peptide-1 (GLP-1) were correlated with changes in appetite over 3 h using visual analogue scores. The post-operative groups at 12, 18 and 24 months had a higher post-prandial PYY response compared to pre-operative (p < 0.05). This finding was confirmed in the prospective study at 18 and 24 months. There was a trend for increasing GLP-1 response at 18 and 24 months, but this did not reach statistical significance (p = 0.189) in the prospective study. Satiety was significantly reduced in the post-operative groups at 12, 18 and 24 months compared to pre-operative levels (p < 0.05). Roux-en-Y gastric bypass causes an enhanced gut hormone response and increased satiety following a meal. This response is sustained over a 24-month period and may partly explain why weight loss is maintained.

2017-01-09

Cross-sectional analyses of adiposity and sleep duration in younger adults suggest that increased adiposity is associated with shorter sleep. Prospective studies have yielded mixed findings, and the direction of this association in older adults is unclear. We examined the cross-sectional and potential bi-directional, prospective associations between adiposity and sleep duration (covariates included demographics, health behaviours, and health problems) in 5,015 respondents from the English Longitudinal Study of Ageing (ELSA), at baseline and follow-up. Following adjustment for covariates, we observed no significant cross-sectional relationship between body mass index (BMI) and sleep duration [(unstandardized) B = -0.28 minutes, (95% Confidence Intervals (CI) = -0.012; 0.002), p = 0.190], or waist circumference (WC) and sleep duration [(unstandardized) B = -0.10 minutes, (95% CI = -0.004; 0.001), p = 0.270]. Prospectively, both baseline BMI [B = -0.42 minutes, (95% CI = -0.013; -0.002), p = 0.013] and WC [B = -0.18 minutes, (95% CI = -0.005; -0.000), p = 0.016] were associated with decreased sleep duration at follow-up, independently of covariates. There was, however, no association between baseline sleep duration and change in BMI or WC (p > 0.05). In older adults, our findings suggested that greater adiposity is associated with decreases in sleep duration over time; however the effect was very small.

To determine the incidence of surgical site infections and to identify risk factors for infections. A prospective study of surgical site infections (SSI) after cesarean section was carried out from September 1997 to September 1998 (pilot study) and from January 2000 to August 2003, using the methodology of the American National Nosocomial Infection Surveillance System. Follow up of women was performed by midwives until discharge and during the post-natal visit. Suspected surgical site infections were confirmed by surgeons and infection control practitioners. The microbiological file of each patient was edited 30 days after cesarean section. Risk factors were analyzed using a logistic regression model. During the pilot study, infection rate was estimated at 3.2%. At multivariate analysis, factors independently associated with an increased risk of SSI were ASA score > 1, performance of cesarean section in a room not dedicated to this activity, and use of an open urine drainage system. During the following years (2000-2003), infection rates progressively decreased to reach 1.9% in 2003. Infections included superficial wound infections (involving skin and subcutaneous tissue) (47%), deep wound infections (involving deep and soft tissue (fascia and muscle) (20%) and organ/space infections (i.e. endometritis, pelvic abscess) (33%). Infections occurred after patient discharge in 47.5% of cases and diagnosis was based only on clinical findings in 30% of cases. Infected patients were hospitalized longer (median: 6 days) than non infected patients. Prospective surveillance of SSI led to better awareness of infectious problems among health care workers, to identification of risk factors and evaluation of health procedures. Surveillance contributed to a decrease in nosocomial infections.

Does dairy food intake predict arterial stiffness and blood pressure in men?: Evidence from the Caerphilly Prospective Study.

Arterial stiffness is an independent predictor of cardiovascular disease events and mortality, and like blood pressure, may be influenced by dairy food intake. Few studies have investigated the effects of consumption of these foods on prospective measures of arterial stiffness. The present analysis aimed to investigate the prospective relationship between milk, cheese, cream, and butter consumption and aortic pulse wave velocity, augmentation index, systolic and diastolic blood pressure, as well as cross-sectional relationships between these foods and systolic and diastolic blood pressure and metabolic markers using data from the Caerphilly Prospective Study. Included in this cohort were 2512 men, aged 45 to 59 years, who were followed up at 5-year intervals for a mean of 22.8 years (number follow-up 787). Augmentation index was 1.8% lower in subjects in the highest quartiles of dairy product intake compared with the lowest (P trend=0.021), whereas in the highest group of milk consumption systolic blood pressure was 10.4 mm Hg lower (P trend=0.033) than in nonmilk consumers after a 22.8-year follow-up. Cross-sectional analyses indicated that across increasing quartiles of butter intake, insulin (P trend=0.011), triacylglycerol (P trend=0.023), total cholesterol (P trend=0.002), and diastolic blood pressure (P trend=0.027) were higher. Across increasing groups of milk intake and quartiles of dairy product intake, glucose (P trend=0.032) and triglyceride concentrations (P trend=0.031) were lower, respectively. The present results confirm that consumption of milk predicts prospective blood pressure, whereas dairy product consumption, excluding butter, is not detrimental to arterial stiffness and metabolic markers. Further research is needed to better understand the mechanisms that underpin these relationships.

The "oldest old" are now the fastest growing section of most western populations, yet there are scarcely any data concerning even the common problem of falls amongst the very old. Prospective data collection is encouraged as the most reliable method for researching older people's falls, though in clinical practice guidelines advise taking a history of any recalled falls. This study set out to inform service planning by describing the epidemiology of falls in advanced old age using both retrospectively and prospectively collected falls data. Re-survey of over-90-year-olds in a longitudinal cohort study - cross-sectional interview and intensive 12-month follow-up. 90 women and 20 men participating in a population-based cohort (aged 91-105 years, in care-homes and community-dwelling) recruited from representative general practices in Cambridge, UKMeasurements: Prospective falls data were collected using fall calendars and telephone follow-up for one year after cross-sectional survey including fall history. 58% were reported to have fallen at least once in the previous year and 60% in the 1-year follow-up. The proportion reported to have fallen more than once was lower using retrospective recall of the past year than prospective reports gathered the following year (34% versus 45%), as were fall rates (1.6 and 2.8 falls/person-year respectively). Repeated falls in the past year were more highly predictive of falls during the following year - IRR 4.7, 95% CI 2.6-8.7 - than just one - IRR 3.6, 95% CI 2.0-6.3, using negative binomial regression. Only 1/5 reportedly did not fall during either the year before or after interview. Fall rates in this representative sample of over-90-year-olds are even higher than previous reports from octogenarians. Recalled falls last year, particularly repeated falls, strongly predicted falls during follow-up. Similar proportions of people who fell were reported by retrospective and prospective methods covering two consecutive years. Recall methods may underestimate numbers of repeated falls and the extent of recurrent falling. Professionals caring for people of advanced age can easily ask routinely whether someone has fallen at all, or more than once, in the past year to identify those at high risk of subsequent falls.

Charlemagne-Badal, Sherma J; Lee, Jerry W

2016-04-01

Seventh-day Adventists have been noted for their unique lifestyle, religious practices and longevity. However, we know little about how religion is directly related to health in this group. Specifically, we know nothing about how religious social support is related to hypertension. Using data from the Biopsychosocial Religion and Health Study, we carried out a cross-sectional study of 9581 and a prospective study of 5720 North American Seventh-day Adventists examining new 534 cases of hypertension occurring up to 4 years later. We used binary logistic regression analyses to examine study hypotheses. Of the religious social support variables, in both the cross-sectional and prospective study only anticipated support significantly predicted hypertension, but the relationship was mediated by BMI. There were no significant race or gender differences. The favorable relationships between anticipated support and hypertension appear to be mediated by BMI and are an indication of how this dimension of religion combined with lifestyle promotes good health, specifically, reduced risk of hypertension.

This study aimed to assess cross-sectional and prospective relationships between vigorous physical activity (VPA) and the risk of major chronic diseases among European older adults. Participants were 37 524 older adults who responded to the fourth (in 2011) and fifth (in 2013) wave of the SHARE project, from 13 European countries. Participants answered interview questions about the presence of chronic conditions and VPA. The cross-sectional and prospective association between PA and the number of chronic diseases was assessed using logistic regression models. Among men and women, the prevalence of chronic diseases was significantly lower among those who reported VPA once a week or more than once a week. For men, VPA once a week was prospectively related with lower odds of heart attack, chronic lung disease, Parkinson's disease and Alzheimer's disease. VPA more than once a week was prospectively related with lower odds of having all chronic diseases. Women who engaged in VPA once a week presented lower odds of having chronic diseases, except for hypertension, high blood cholesterol and cancer. For VPA more than once a week, cancer was the only disease not associated with physical activity. VPA is associated with reduced risk of chronic diseases in men and women. Even the practice of VPA once a week seems to be sufficient to reduce risks of chronic diseases.

To assess how enhanced postdischarge telephone follow-up calls would improve case finding for surgical site infection (SSI) surveillance after cesarean section. We conducted a prospective cohort study of all patients who delivered by cesarean section between April 22 and August 22, 2010. In addition to our routine surveillance, using clinical databases and electronic patient records, we also made follow-up calls to the patients at 7, 14, and 30 days postoperation. A standard questionnaire with questions about symptoms of SSI, health-seeking behaviors, and treatment received was administered. Descriptive statistics and univariate analysis were performed to assess the effect of the enhanced surveillance. One hundred ninety-three patients underwent cesarean section during this study period. Standard surveillance identified 14 infections with telephone follow-ups identifying an additional 5 infections. Using the call as a gold standard, the sensitivity of the standard methodology to capture SSI was 73.3%. The duration of the calls ranged from 1 to 5 minutes and were well received by the patients. Results suggest that follow-up telephone calls to patients following cesarean section identifies 26.3% of the total SSIs. Enhanced surveillance can provide more informed data to enhance performance and avoid underestimation of rates.

Hu, Mandy Xian; Lamers, Femke; Neijts, Melanie; Willemsen, Gonneke; de Geus, Eco J C; Penninx, Brenda W J H

2018-06-01

Autonomic nervous system (ANS) imbalance has been cross-sectionally associated with inflammatory processes. Longitudinal studies are needed to shed light on the nature of this relationship. We examined cross-sectional and bidirectional prospective associations between cardiac autonomic measures and inflammatory markers. Analyses were conducted with baseline (n = 2823), 2-year (n = 2099), and 6-year (n = 1774) data from the Netherlands Study of Depression and Anxiety. To compare the pattern of results, prospective analyses with ANS (during sleep, leisure time, and work) and inflammation were conducted in two data sets from the Netherlands Twin Register measured for 4.9 years (n = 356) and 5.4 years (n = 472). Autonomic nervous system measures were heart rate (HR) and respiratory sinus arrhythmia (RSA). Inflammatory markers were C-reactive protein (CRP) and interleukin (IL)-6. The Netherlands Study of Depression and Anxiety results showed that higher HR and lower RSA were cross-sectionally significantly associated with higher inflammatory levels. Higher HR predicted higher levels of CRP (B = .065, p < .001) and IL-6 (B = .036, p = .014) at follow-up. Higher CRP levels predicted lower RSA (B = -.024, p = .048) at follow-up. The Netherlands Twin Register results confirmed that higher HR was associated with higher CRP and IL-6 levels 4.9 years later. Higher IL-6 levels predicted higher HR and lower RSA at follow-up. Autonomic imbalance is associated with higher levels of inflammation. Independent data from two studies converge in evidence that higher HR predicts subsequent higher levels of CRP and IL-6. Inflammatory markers may also predict future ANS activity, but evidence for this was less consistent.

Berglind, D; Ljung, R; Tynelius, P; Brooke, H L

2018-01-31

Cross-sectional studies report that meeting the newly developed 24-h movement guidelines (≥60 min moderate to vigorous physical activity (MVPA), ≤120 min screen time and 9-11 h sleep duration) are associated with lower adiposity indicators in children. However, prospective data are absent. The study sample consisted of 830 children from the PRIMROSE study with GT3X+ accelerometer measured physical activity and parent reported screen time and sleep duration at age 4 years and objectively measured anthropometrics at age 4 and 5 years. The main outcome variables were weight status, body mass index (BMI) and BMI z-score at ages 4 and 5 years. Exposure variables were defined as meeting vs. not meeting the 24-h movement guidelines and combinations of these recommendations. On average, 18.4% of the total study sample met the combination of MVPA, sleep duration and screen time recommendations. In isolation, the MVPA, screen time and sleep guidelines were met by 31%, 63% and 98% of the total study sample, respectively. Adherence to any single recommendation, or any combination of recommendations at age 4 years, was not associated with being overweight or obese nor with BMI and BMI z-score at age 4 or 5 years. In contrast to previous cross-sectional studies, neither individual movement behaviours nor combinations of behaviours at age 4 years was associated with overweight or obesity, BMI or BMI z-score at age 4 or 5 years. More prospective data are needed before effects on weight status from meeting the 24-h movement guidelines are elucidated. © 2018 World Obesity Federation.

Investigations of the petrogeneration zones western Bering sea by airborne geophysical data

NASA Astrophysics Data System (ADS)

Litvinova, T.; Petrova, A.

2012-04-01

In 2011, work continued on the interpretation of geophysical data in western Bering Sea. Bering Sea oil-and-gas bearing province occupies a single sedimentary megabasin of the Bering Sea, the formation of which is caused by stage of the Alpine geodynamic development cycle of the Pacific mobile belt. At present, the geological-geophysical exploration maturity of the Bering Sea with respect to oil-gasbearing prognosis is at the level of regional study stage. In 2003, an additional study of oil-gas prospective zones of the Kamchatka Shelf of the Bering Sea was carried out. In the course of works, profile seismic studies and airborne gravity-magnetic survey at 1:200,000 scale were made at three territories: Ilpinsky, Olyutorsky I, and Olyutorsky II. Average survey elevation for the whole area is 300 meters. Geological modeling of sedimentary basin systems was made for this area. Geomagnetic sections it possible to compare the location of the magnetic and weakly magnetic structures with seismic and geological boundaries marker and conducting layers of geoelectric sections. This makes it possible to trace the features of placing magnetic differences in the geologic rock section, to identify their stratigraphic association, select the layers flyuidstubborn, adumbrate reservoir heterogeneity and establish the heterogeneity of internal structure oil-gasbearing zones. Age correlation, thickness estimation and formational characteristics of litho-stratigraphic complexes building up sections are carried out. Geomagnetic deep sections transecting main zones of prospective oil-gas accumulation to airborne magnetic data. Distribution of magnetization in the development interval of potentially productive sandy strata at depths from 1 to 5 km is obtained. The most prospective zones of possible oil-gas accumulation are distinguished in the Olyutorsky and Ilpinsky sedimentary basins. At height of 400 km this minimum keeps the form that speaks about stability of a condition of the permeable zones supervising oil-gas-bearing.

The role of insulin-like growth factors (IGFs) in prostate cancer development is not fully understood. To investigate the association between circulating concentrations of IGFs (IGF-I, IGF-II, IGFBP-1, IGFBP-2, IGFBP-3) and prostate cancer risk, we pooled individual participant data from 17 prospective and two cross-sectional studies, including up to 10,554 prostate cancer cases and 13,618 control participants. Conditional logistic regression was used to estimate the odds ratios (ORs) for prostate cancer based on the study-specific fifth of each analyte. Overall, IGF-I, IGF-II, IGFBP-2, and IGFBP-3 concentrations were positively associated with prostate cancer risk (Ptrend all ≤ 0.005), and IGFBP-1 was weakly inversely associated with risk (Ptrend = 0.05). However, heterogeneity between the prospective and cross-sectional studies was evident (Pheterogeneity = 0.03), unless the analyses were restricted to prospective studies (with the exception of IGF-II, Pheterogeneity = 0.02). For prospective studies, the OR for men in the highest versus the lowest fifth of each analyte was 1.29 (95% confidence interval=1.16-1.43) for IGF-I, 0.81 (0.68-0.96) for IGFBP-1, and 1.25 (1.12-1.40) for IGFBP-3. These associations did not differ significantly by time-to-diagnosis or tumor stage or grade. After mutual adjustment for each of the other analytes, only IGF-I remained associated with risk. Our collaborative study represents the largest pooled analysis of the relationship between prostate cancer risk and circulating concentrations of IGF-I, providing strong evidence that IGF-I is highly likely to be involved in prostate cancer development.

Internet Addiction and Psychosocial Maladjustment: Avoidant Coping and Coping Inflexibility as Psychological Mechanisms.

PubMed

Cheng, Cecilia; Sun, Peizhen; Mak, Kwok-Kei

2015-09-01

This 6 month prospective study systematically tested some multivariate models that advanced the understanding of the psychological mechanisms underlying Internet addiction and psychosocial maladjustment. On the basis of previous theories, avoidant coping and coping inflexibility were proposed as underlying mechanisms. Participants were 271 Chinese undergraduates (75% women, Mage=20.49) who took part in both phases of this study. Structural equation modeling was performed to obtain the best fit models for both the cross-sectional and the prospective data. The cross-sectional model testing revealed statistically significant mediating effects for both avoidant coping (β=0.149 [95% CI 0.071-0.226], p=0.002) and coping flexibility (β=0.048 [95% CI 0.013-0.081], p=0.032). The prospective model testing further showed that avoidant coping mediated the relationship between Internet addiction and Time 2 psychosocial maladjustment (β=0.141 [95% CI 0.065-0.216], p=0.005), as well as that between coping flexibility and Time 2 psychosocial maladjustment (β=-0.096 [95% CI -0.161 to -0.031], p=0.015). This study was the first to establish theory-driven models, which unveiled an inflexible, avoidant coping style as psychological mechanisms that explained the link between Internet addiction and psychosocial maladjustment.

Translating Stem Cell Research to Cardiac Disease Therapies: Pitfalls and Prospects for Improvement

PubMed Central

Rosen, Michael R.; Myerburg, Robert J.; Francis, Darrel P.; Cole, Graham D.; Marbán, Eduardo

2014-01-01

Over the past 2 decades, there have been numerous stem cell studies focused on cardiac diseases, ranging from proof-of-concept to phase 2 trials. This series of articles focuses on the legacy of these studies and the outlook for future treatment of cardiac diseases with stem cell therapies. The first section by Rosen and Myerburg is an independent review that analyzes the basic science and translational strategies supporting the rapid advance of stem cell technology to the clinic, the philosophies behind them, trial designs, and means for going forward that may impact favorably on progress. The second and third sections were collected in response to the initial section of this review. The commentary by Francis and Cole discusses the Rosen and Myerburg review and details how trial outcomes can be affected by noise, poor trial design (particularly the absence of blinding), and normal human tendencies toward optimism and denial. The final, independent article by Marbán takes a different perspective concerning the potential for positive impact of stem cell research applied to heart disease and future prospects for its clinical application.

Rates of caesarean section have steadily increased in most middle- and high-income countries over the last few decades without medical justification. Maternal request is one of the frequently cited non-medical factors contributing to this trend. The objectives of this study were to assess pregnant women's preferences regarding mode of delivery and to compare actual caesarean section rates in the public and private sectors. A prospective cohort study was conducted in two public and three private hospitals in Buenos Aires, Argentina. 382 nulliparous pregnant women (183 from the private sector and 199 from the public sector) aged 18 to 35 years, with single pregnancies over 32 weeks of gestational age were enrolled during antenatal care visits between October 2010 and September 2011. We excluded women with pregnancies resulting from assisted fertility, women with known pre-existing major diseases or, with pregnancy complications, or with a medical indication of elective cesarean section. We used two different approaches to assess women's preferences: a survey using a tailored questionnaire, and a discrete choice experiment. Only 8 and 6% of the healthy nulliparous women in the public and private sectors, respectively, expressed a preference for caesarean section. Fear of pain and safety were the most frequently expressed reasons for preferring caesarean section. When reasons for delivery mode were assessed by a discrete choice experiment, women placed the most emphasis on sex after childbirth. Of women who expressed their preference for vaginal delivery, 34 and 40% ended their pregnancies by caesarean section in public and private hospitals, respectively. The preference for caesarean section is low among healthy nulliparous women in Buenos Aires. The reasons why these women had a rate of more than 35% caesarean sections are unlikely related to their preferences for mode of delivery.

Suicide and religion.

2017-01-01

Cross-sectional analyses of adiposity and sleep duration in younger adults suggest that increased adiposity is associated with shorter sleep. Prospective studies have yielded mixed findings, and the direction of this association in older adults is unclear. We examined the cross-sectional and potential bi-directional, prospective associations between adiposity and sleep duration (covariates included demographics, health behaviours, and health problems) in 5,015 respondents from the English Longitudinal Study of Ageing (ELSA), at baseline and follow-up. Following adjustment for covariates, we observed no significant cross-sectional relationship between body mass index (BMI) and sleep duration [(unstandardized) B = −0.28 minutes, (95% Confidence Intervals (CI) = −0.012; 0.002), p = 0.190], or waist circumference (WC) and sleep duration [(unstandardized) B = −0.10 minutes, (95% CI = −0.004; 0.001), p = 0.270]. Prospectively, both baseline BMI [B = −0.42 minutes, (95% CI = −0.013; −0.002), p = 0.013] and WC [B = −0.18 minutes, (95% CI = −0.005; −0.000), p = 0.016] were associated with decreased sleep duration at follow-up, independently of covariates. There was, however, no association between baseline sleep duration and change in BMI or WC (p > 0.05). In older adults, our findings suggested that greater adiposity is associated with decreases in sleep duration over time; however the effect was very small. PMID:28067295

There has been increased emphasis in orthopaedics on high-quality prospective research to provide evidence-based treatment guidelines, particularly in sports medicine/shoulder surgery. The external validity of these studies has not been established, and the generalizability of the results to clinical practice in the United States is unknown. Comparison of patient demographics in major prospective studies of arthroscopic sports and shoulder surgeries to patients undergoing the same procedures in the National Surgical Quality Improvement Program (NSQIP) database will show substantial differences to question the generalizability and external validity of those studies. Cross-sectional study; Level of evidence, 3. This study utilized patients undergoing arthroscopic anterior cruciate ligament reconstruction (ACLR), meniscectomy (MX), rotator cuff repair (RCR), and shoulder stabilization (SS) from the NSQIP database (2005-2013). Two prospective studies (either randomized controlled trials or, in 1 case, a major cohort study) were identified for each of the 4 procedures for comparison. Demographic variables available for comparison in both the identified prospective studies and the NSQIP included age, sex, and body mass index (BMI). From the NSQIP database, 5576 ACLR patients, 18,882 MX patients, 7282 RCR patients, and 993 SS patients were identified. The comparison clinical studies included cohort sizes as follows: ACLR, n = 121 and 2683; MX, n = 146 and 330; RCR, n = 90 and 103; SS, n = 88 and 196. Age differed significantly between the NSQIP and the patients in 6 of the 8 prospective clinical studies. Sex differed significantly between the NSQIP and the patients in 7 of the 8 prospective clinical studies. BMI differed significantly between the NSQIP and the patients of all 4 of the prospective clinical studies that reported this demographic variable. Significant differences exist for patient age, sex, and BMI between patients included in major sports medicine/shoulder prospective studies and corresponding patients undergoing the same procedures in a nationwide database of academic and community centers in the United States. Future work is needed to understand whether major prospective clinical studies-frequently performed in high-volume, specialized practices-are truly indicative of the types of patients treated and expected results in the general orthopaedic practice. This study additionally argues for the importance of initiating a national registry dedicated to patients undergoing orthopaedic procedures in the United States.

Lay Awareness of the Relationship between Age and Cancer Risk.

2017-04-01

Cross-sectional studies suggest many people are unaware that cancer risk increases with age, but this misbelief has rarely been studied prospectively, nor are its moderators known. To assess whether people recognize that cancer risk increases with age and whether beliefs differ according to gender, education, smoking status, and family history of cancer. First, items from the cross-sectional Health Information National Trends Survey (n = 2069) were analyzed to examine the association of age and perceived cancer risk. Second, the prospective National Survey of Midlife Development in the United States (n = 3896) was used to assess whether perceived cancer risk changes over a decade. Third, beliefs about the age at which cancer occurs were analyzed using the US Awareness and Beliefs about Cancer survey (n = 1080). As a comparator, perceived risk of heart disease was also examined. Cross-sectionally, older age was associated with lower perceived cancer risk but higher perceived heart disease risk. Prospectively, perceived cancer risk remained stable, whereas perceived heart attack risk increased. Seventy percent of participants reported a belief that cancer is equally likely to affect people of any age. Across three surveys, women and former smokers/smokers who recently quit tended to misunderstand the relationship between age and cancer risk and also expressed relatively higher perceived cancer risk overall. Data from three national surveys indicated that people are unaware that age is a risk factor for cancer. Moreover, those who were least aware perceived the highest risk of cancer regardless of age.

2017-04-01

Journals provide instructions to prospective authors to facilitate the process of manuscript publication. The information provided under such instructions could be a potential opportunity to promote responsible conduct of research (RCR). We analyzed 74 Indian biomedical journals for the type of information provided in the "instructions to authors" section and adherence to the International Committee of Medical Journal Editors (ICMJE) recommendations. Among the 71 journals that had an "instructions to authors" section, 53 journals adhered to ICMJE recommendations. We discuss sections of the ICMJE recommendations detailed by Indian biomedical journals under the "instructions to authors" section and emphasize components that require greater exposure.

Shame and guilt as shared vulnerability factors: Shame, but not guilt, prospectively predicts both social anxiety and bulimic symptoms.

2016-08-01

Social anxiety disorder (SAD) and bulimia nervosa (BN) are highly comorbid. However, little is known about the shared vulnerability factors that prospectively predict both SA and BN symptoms. Two potential factors that have not yet been tested are shame and guilt. In the current study we tested if shame and guilt were shared vulnerability factors for SA and BN symptoms. Women (N=300) completed measures of SA symptoms, BN symptoms, state shame and guilt, and trait negative affect at two time points, two months apart. Utilizing structural equation modeling we tested a cross-sectional and prospective model of SA and BN vulnerability. We found that shame prospectively predicted both SA and BN symptoms. We did not find that guilt prospectively predicted SA or BN symptoms. However, higher levels of both BN and SA symptoms predicted increased guilt over time. We found support for shame as a shared prospective vulnerability factor between BN and SA symptoms. Interventions that focus on decreasing shame could potentially alleviate symptoms of BN and SA in one protocol. Copyright © 2016 Elsevier Ltd. All rights reserved.

Are scabies and impetigo “normalised”? A cross-sectional comparative study of hospitalised children in northern Australia assessing clinical recognition and treatment of skin infections

PubMed Central

Anderson, Aleisha; Cleland, Gavin; Bowen, Asha C.

2017-01-01

Background Complications of scabies and impetigo such as glomerulonephritis and invasive bacterial infection in Australian Aboriginal children remain significant problems and the overall global burden of disease attributable to these skin infections remains high despite the availability of effective treatment. We hypothesised that one factor contributing to this high burden is that skin infection is under-recognised and hence under-treated, in settings where prevalence is high. Methods We conducted a prospective, cross-sectional study to assess the burden of scabies, impetigo, tinea and pediculosis in children admitted to two regional Australian hospitals from October 2015 to January 2016. A retrospective chart review of patients admitted in November 2014 (mid-point of the prospective data collection in the preceding year) was performed. Prevalence of documented skin infection was compared in the prospective and retrospective population to assess clinician recognition and treatment of skin infections. Results 158 patients with median age 3.6 years, 74% Aboriginal, were prospectively recruited. 77 patient records were retrospectively reviewed. Scabies (8.2% vs 0.0%, OR N/A, p = 0.006) and impetigo (49.4% vs 19.5%, OR 4.0 (95% confidence interval [CI 2.1–7.7) were more prevalent in the prospective analysis. Skin examination was only documented in 45.5% of cases in the retrospective review. Patients in the prospective analysis were more likely to be prescribed specific treatment for skin infection compared with those in the retrospective review (31.6% vs 5.2%, OR 8.5 (95% CI 2.9–24.4). Conclusions Scabies and impetigo infections are under-recognised and hence under-treated by clinicians. Improving the recognition and treatment of skin infections by clinicians is a priority to reduce the high burden of skin infection and subsequent sequelae in paediatric populations where scabies and impetigo are endemic.

Falls in advanced old age: recalled falls and prospective follow-up of over-90-year-olds in the Cambridge City over-75s Cohort study

PubMed Central

Fleming, Jane; Matthews, Fiona E; Brayne, Carol

2008-01-01

Background The "oldest old" are now the fastest growing section of most western populations, yet there are scarcely any data concerning even the common problem of falls amongst the very old. Prospective data collection is encouraged as the most reliable method for researching older people's falls, though in clinical practice guidelines advise taking a history of any recalled falls. This study set out to inform service planning by describing the epidemiology of falls in advanced old age using both retrospectively and prospectively collected falls data. Methods Design: Re-survey of over-90-year-olds in a longitudinal cohort study – cross-sectional interview and intensive 12-month follow-up. Participants and setting: 90 women and 20 men participating in a population-based cohort (aged 91–105 years, in care-homes and community-dwelling) recruited from representative general practices in Cambridge, UK Measurements: Prospective falls data were collected using fall calendars and telephone follow-up for one year after cross-sectional survey including fall history. Results 58% were reported to have fallen at least once in the previous year and 60% in the 1-year follow-up. The proportion reported to have fallen more than once was lower using retrospective recall of the past year than prospective reports gathered the following year (34% versus 45%), as were fall rates (1.6 and 2.8 falls/person-year respectively). Repeated falls in the past year were more highly predictive of falls during the following year – IRR 4.7, 95% CI 2.6–8.7 – than just one – IRR 3.6, 95% CI 2.0–6.3, using negative binomial regression. Only 1/5 reportedly did not fall during either the year before or after interview. Conclusion Fall rates in this representative sample of over-90-year-olds are even higher than previous reports from octogenarians. Recalled falls last year, particularly repeated falls, strongly predicted falls during follow-up. Similar proportions of people who fell were reported by retrospective and prospective methods covering two consecutive years. Recall methods may underestimate numbers of repeated falls and the extent of recurrent falling. Professionals caring for people of advanced age can easily ask routinely whether someone has fallen at all, or more than once, in the past year to identify those at high risk of subsequent falls.

Post-traumatic stress disorder (PTSD) occurs in 1-7% of women following childbirth. While having a caesarean section (C-section) is known to be a significant risk factor for postpartum PTSD, it is currently unknown whether coexisting anaesthesia-related factors are also associated to the disorder. The aim of this study was to assess anaesthesia-linked factors in the development of acute postpartum PTSD. We performed a prospective cohort study on women having a C-section in a tertiary hospital in Switzerland. Patients were followed up six weeks postpartum. Patient and procedure characteristics, past morbidity or traumatic events, psychosocial status and stressful perinatal events were measured. Outcome was divided into two categories: full PTSD disease and PTSD profile. This was based on the number of DSM-IV criteria of the Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM-IV) present. The PTSD Checklist Scale and the Clinician Administered PTSD Scale were used for measurement. Of the 280 patients included, 217 (77.5%) answered the questionnaires and 175 (62.5%) answered to an additional phone interview. Twenty (9.2%) had a PTSD profile and six (2.7%) a PTSD. When a full predictive model of risk factors for PTSD profile was built using logistic regression, maternal prepartum and intrapartum complications, anaesthetic complications and dissociative experiences during C-section were found to be the significant predictors for PTSD profile. This is the first study to show in parturients having a C-section that an anaesthesia complication is an independent risk factor for postpartum PTSD and PTSD profile development, in addition to known perinatal and maternal risk factors.

This study was conducted to establish (a) the stability of the DSM-5 Section III personality disorder (PD) traits, (b) whether these traits predict future psychosocial functioning, and (c) whether changes in traits track with changes in psychosocial functioning across time. Ninety-three outpatients (61% female) diagnosed with at least 1 PD completed patient-report measures at 2 time-points (M time between assessments = 1.44 years), including the Personality Inventory for the DSM-5 and several measures of psychosocial functioning. Effect sizes of rank-order and mean-level change were calculated. In addition, Time 1 traits were used to predict functioning measures at Time 2. Finally, latent change score models were estimated for DSM-5 Section III traits and functioning measures, and correlations among latent change scores were calculated to establish the relationship between change in traits and functional outcomes. Findings demonstrated that the DSM-5 Section III traits were highly stable in terms of normative (i.e., mean-level) change and rank-order stability over the course of the study. Furthermore, traits prospectively predicted psychosocial functioning. However, at the individual level traits and functioning were not entirely static over the study, and change in individuals' functioning tracked with changes in trait levels. These findings demonstrate that the DSM-5 Section III traits are highly stable consistent with the definition of PD, prospectively predictive of psychosocial functioning, and are dynamically associated with functioning over time. This study provides important evidence in support of the DSM-5 Section III PD model. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

Accumulating evidence suggests an association between coronary heart disease and risk for cognitive impairment or dementia, but no study has systematically reviewed this association. Therefore, we summarized the available evidence on the association between coronary heart disease and risk for cognitive impairment or dementia. Medline, Embase, PsycINFO, and CINAHL were searched for all publications until 8th January 2016. Articles were included if they fulfilled the inclusion criteria: (1) myocardial infarction, angina pectoris or coronary heart disease (combination of both) as predictor variable; (2) cognition, cognitive impairment or dementia as outcome; (3) population-based study; (4) prospective (≥1 year follow-up), cross-sectional or case-control study design; (5) ≥100 participants; and (6) aged ≥45 years. Reference lists of publications and secondary literature were hand-searched for possible missing articles. Two reviewers independently screened all abstracts and extracted information from potential relevant full-text articles using a standardized data collection form. Study quality was assessed with the Newcastle-Ottawa Scale. We pooled estimates from the most fully adjusted model using random-effects meta-analysis. We identified 6,132 abstracts, of which 24 studies were included. A meta-analysis of 10 prospective cohort studies showed that coronary heart disease was associated with increased risk of cognitive impairment or dementia (OR = 1.45, 95%CI = 1.21-1.74, p<0.001). Between-study heterogeneity was low (I2 = 25.7%, 95%CI = 0-64, p = 0.207). Similar significant associations were found in separate meta-analyses of prospective cohort studies for the individual predictors (myocardial infarction, angina pectoris). In contrast, meta-analyses of cross-sectional and case-control studies were inconclusive. This meta-analysis suggests that coronary heart disease is prospectively associated with increased odds of developing cognitive impairment or dementia. Given the projected worldwide increase in the number of people affected by coronary heart disease and dementia, insight into causal mechanisms or common pathways underlying the heart-brain connection is needed.

Background The optimal reference range of homeostasis model assessment of insulin resistance (HOMA-IR) in normal Chinese population has not been clearly defined. Here we address this issue using the Hong Kong Cardiovascular Risk Factor Prevalence Study (CRISPS), a prospective population-based cohort study with long-term follow-up. Material & Methods In this study, normal glucose tolerance (NGT), impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and type 2 diabetes mellitus (T2DM) were defined according to the 1998 World Health Organization criteria. Dysglycemia referred to IFG, IGT or T2DM. This study comprised two parts. Part one was a cross-sectional study involving 2,649 Hong Kong Chinese subjects, aged 25–74 years, at baseline CRISPS-1 (1995–1996). The optimal HOMA-IR cut-offs for dysglycemia and T2DM were determined by the receiver-operating characteristic (ROC) curve. Part two was a prospective study involving 872 subjects who had persistent NGT at CRISPS-4 (2010–2012) after 15 years of follow-up. Results At baseline, the optimal HOMA-IR cut-offs to identify dysglyceia and T2DM were 1.37 (AUC = 0.735; 95% confidence interval [CI] = 0.713–0.758; Sensitivity [Se] = 65.6%, Specificity [Sp] = 71.3%] and 1.97 (AUC = 0.807; 95% CI = 0.777–0.886; Se = 65.5%, Sp = 82.9%) respectively. These cut-offs, derived from the cross-sectional study at baseline, corresponded closely to the 75th (1.44) and 90th (2.03) percentiles, respectively, of the HOMA-IR reference range derived from the prospective study of subjects with persistent NGT. Conclusions HOMA-IR cut-offs, of 1.4 and 2.0, which discriminated dysglycemia and T2DM respectively from NGT in Southern Chinese, can be usefully employed as references in clinical research involving the assessment of insulin resistance.

Mobile phone use and stress, sleep disturbances, and symptoms of depression among young adults - a prospective cohort study

PubMed Central

2011-01-01

Background Because of the quick development and widespread use of mobile phones, and their vast effect on communication and interactions, it is important to study possible negative health effects of mobile phone exposure. The overall aim of this study was to investigate whether there are associations between psychosocial aspects of mobile phone use and mental health symptoms in a prospective cohort of young adults. Methods The study group consisted of young adults 20-24 years old (n = 4156), who responded to a questionnaire at baseline and 1-year follow-up. Mobile phone exposure variables included frequency of use, but also more qualitative variables: demands on availability, perceived stressfulness of accessibility, being awakened at night by the mobile phone, and personal overuse of the mobile phone. Mental health outcomes included current stress, sleep disorders, and symptoms of depression. Prevalence ratios (PRs) were calculated for cross-sectional and prospective associations between exposure variables and mental health outcomes for men and women separately. Results There were cross-sectional associations between high compared to low mobile phone use and stress, sleep disturbances, and symptoms of depression for the men and women. When excluding respondents reporting mental health symptoms at baseline, high mobile phone use was associated with sleep disturbances and symptoms of depression for the men and symptoms of depression for the women at 1-year follow-up. All qualitative variables had cross-sectional associations with mental health outcomes. In prospective analysis, overuse was associated with stress and sleep disturbances for women, and high accessibility stress was associated with stress, sleep disturbances, and symptoms of depression for both men and women. Conclusions High frequency of mobile phone use at baseline was a risk factor for mental health outcomes at 1-year follow-up among the young adults. The risk for reporting mental health symptoms at follow-up was greatest among those who had perceived accessibility via mobile phones to be stressful. Public health prevention strategies focusing on attitudes could include information and advice, helping young adults to set limits for their own and others' accessibility. PMID:21281471

Employee control over work times has been associated with favorable psychosocial and health-related outcomes, but the evidence regarding sleep quality remains inconclusive. We examined cross-sectional and prospective associations between work time control and sleep disturbances in a large working population, taking into account total hours worked. The data were from a full-panel longitudinal cohort study of Finnish public sector employees who responded to questions on work time control and sleep disturbances in years 2000-2001, 2004-2005, 2008-2009, and 2012. The analysis of cross-sectional associations was based on 129,286 person measurements from 68,089 participants (77% women) aged 17-73 years (mean 43.1). Data from 16,503 participants were used in the longitudinal analysis. Log-binomial regression analysis with the generalized estimating equations method was used. Consistently in both cross-sectional and longitudinal models, less control over work time was associated with greater sleep disturbances in the total population and among those working normal 40-hour weeks. Among participants working more than 40 hours a week, work time that was both very high (cross-sectional prevalence ratio compared to intermediate work time control [PR] 1.32, 95% confidence interval [CI] 1.05-1.65) and very low (PR 1.23, 95% CI 1.08-1.39) was associated with sleep disturbances, after adjustment for potential confounding factors. These data suggest that having few opportunities to influence the duration and positioning of work time may increase the risk of sleep disturbances among employees. For persons working long hours, very high levels of control over working times were also associated with increased risk of sleep disturbances.

Factors associated with exercise adherence among older adults. An individual perspective.

PubMed

Rhodes, R E; Martin, A D; Taunton, J E; Rhodes, E C; Donnelly, M; Elliot, J

1999-12-01

This paper reviews the literature concerning factors at the individual level associated with regular exercise among older adults. Twenty-seven cross-sectional and 14 prospective/longitudinal studies met the inclusion criteria of a mean participant age of 65 years or older. The findings are summarised by demographics, exercise experience, exercise knowledge, physiological factors, psychological factors, activity preferences and perceived social influences. In general, education and exercise history correlate positively with regular exercise, while perceived physical frailty and poor health may provide the greatest barrier to exercise adoption and adherence in the elderly. Social-cognitive theories identify several constructs that correlate with the regular exercise behaviour of older adults, such as exercise attitude, perceived behavioural control/self-efficacy, perceived social support and perceived benefits/barriers to continued activity. As well, stage modelling may provide additional information about the readiness for regular exercise behaviour among older adults. However, relatively few studies among older adults exist compared with middle-aged and younger adults. Further, the majority of current research consists of cross-sectional designs or short prospective exercise trials among motivated volunteers that may lack external validity. Future research utilising longitudinal and prospective designs with representative samples of older adults will provide a better understanding of significant causal associations between individual factors and regular exercise behaviour.

A prospective study of differential sources of school-related social support and adolescent global life satisfaction.

Siddall, James; Huebner, E Scott; Jiang, Xu

2013-01-01

This study examined the cross-sectional and prospective relationships between three sources of school-related social support (parent involvement, peer support for learning, and teacher-student relationships) and early adolescents' global life satisfaction. The participants were 597 middle school students from 1 large school in the southeastern United States who completed measures of school social climate and life satisfaction on 2 occasions, 5 months apart. The results revealed that school-related experiences in terms of social support for learning contributed substantial amounts of variance to individual differences in adolescents' satisfaction with their lives as a whole. Cross-sectional multiple regression analyses of the differential contributions of the sources of support demonstrated that family and peer support for learning contributed statistically significant, unique variance to global life satisfaction reports. Prospective multiple regression analyses demonstrated that only family support for learning continued to contribute statistically significant, unique variance to the global life satisfaction reports at Time 2. The results suggest that school-related experiences, especially family-school interactions, spill over into adolescents' overall evaluations of their lives at a time when direct parental involvement in schooling and adolescents' global life satisfaction are generally declining. Recommendations for future research and educational policies and practices are discussed. © 2013 American Orthopsychiatric Association.

Compounds in cocoa and chocolate have established cardiovascular benefits, including beneficial effects on insulin resistance, a risk factor for type 2 diabetes mellitus. The aims of this study was to investigate relations between habitual chocolate intakes and diabetes mellitus. Cross-sectional and prospective analyses were undertaken on 953 community-dwelling participants (mean age 62 years, 59% women) from the Maine-Syracuse Longitudinal Study (MSLS). Habitual chocolate intakes, measured using a food frequency questionnaire, were related to prevalence of diabetes mellitus (cross-sectionally) and with risk of diabetes measured approximately five years later (prospectively). We also examined the relation between diabetes (the predictor) and chocolate consumption (the outcome) up to 30 years later. Chocolate intake was inversely associated with type 2 diabetes. Compared to participants who consumed chocolate more than once per week, those who never or rarely ate chocolate exhibited a significantly higher odds of having type 2 diabetes 5 years later (OR: 1.91, 95% CI: 1.03, 3.55, p = 0.04), after adjustment for cardiovascular, lifestyle and dietary factors including other polyphenol-rich beverages. However, individuals diagnosed with diabetes prior to the nutritional assessment consumed lower amounts of chocolate at the time of the dietary assessment. Our findings suggest that relations between chocolate and type 2 diabetes may be bi-directional. Copyright © 2016 Elsevier Ltd. All rights reserved.

Epidemiologic studies report conflicting results for the relationship between milk intake and adiposity in children. We examined prospective and cross-sectional associations between milk intake and percent body fat among 2245 children from the Avon Longitudinal Study of Parents and Children. Cross-sectional analyses were performed at age 13 y between total, full-fat, and reduced-fat milk intake assessed using 3-d dietary records and body fat from DXA. Prospective analyses were conducted between milk intakes at age 10 y and body fat at 11 and 13 y. Models were adjusted for age, sex, height, physical activity, pubertal status, maternal BMI, maternal education, and intakes of total fat, sugar-sweetened beverages, 100% fruit juice, and ready-to-eat cereals; baseline BMI was added to prospective models. Subset analyses were performed for those with plausible dietary intakes. Mean milk consumption at 10 and 13 y was (mean ± SD) 0.90 ± 0.73 and 0.85 ± 0.78 servings/d [1 serving = 8 oz of milk (244 g of plain and 250 g flavored milk)], respectively. Cross-sectional results indicated an inverse association between full-fat milk intake and body fat [β = −0.47 (95% CI = −0.76, −0.19); P = 0.001]. Milk intake at age 10 y was inversely associated with body fat at 11 y [β = −0.16 g/d (95%CI = −0.28, −0.04); P = 0.01], but not among those with plausible dietary intakes, suggesting that this association was influenced by dietary measurement errors. Milk intake was not associated with body fat at age 13 y after adjustment. Although our prospective results corroborate other findings of a null associations between milk intake and adiposity, our inconsistent findings across analyses suggest further investigation is needed to clarify the relation, and accounting for dietary reporting errors is an important consideration.

Little is known about the association between iodine and human milk composition. In this study, we investigated the association between iodine and different markers of oxidative stress and obesity-related hormones in human breast milk. This work is composed of two cross-sectional studies (in lactating women and in the general population), one prospective and one in vitro. In the cross-sectional study in lactating women, the breast milk iodine correlated negatively with superoxide dismutase (SOD), catalase, and glutathione peroxidase (GSH-Px) activities, and with adiponectin levels. An in vitro culture of human adipocytes with 1 μM potassium iodide (KI, dose similar to the human breast milk iodine concentration) produced a significant decrease in adiponectin, GSH-Px, SOD1, and SOD2 mRNA expression. However, after 2 months of treatment with KI in the prospective study, a positive correlation was found between 24-h urinary iodine and serum adiponectin. Our observations lead to the hypothesis that iodine may be a factor directly involved in the regulation of oxidative stress and adiponectin levels in human breast milk.

Objective To establish reference charts for fetal cerebellar vermis height in an unselected population. Methods A prospective cross-sectional study between September 2009 and December 2014 was carried out at ALTAMEDICA Fetal–Maternal Medical Centre, Rome, Italy. Of 25203 fetal biometric measurements, 12167 (48%) measurements of the cerebellar vermis were available. After excluding 1562 (12.8%) measurements, a total of 10605 (87.2%) fetuses were considered and analyzed once only. Parametric and nonparametric quantile regression models were used for the statistical analysis. In order to evaluate the robustness of the proposed reference charts regarding various distributional assumptions on the ultrasound measurements at hand, we compared the gestational age-specific reference curves we produced through the statistical methods used. Normal mean height based on parametric and nonparametric methods were defined for each week of gestation and the regression equation expressing the height of the cerebellar vermis as a function of gestational age was calculated. Finally the correlation between dimension/gestation was measured. Results The mean height of the cerebellar vermis was 12.7mm (SD, 1.6mm; 95% confidence interval, 12.7–12.8mm). The regression equation expressing the height of the CV as a function of the gestational age was: height (mm) = -4.85+0.78 x gestational age. The correlation between dimension/gestation was expressed by the coefficient r = 0.87. Conclusion This is the first prospective cross-sectional study on fetal cerebellar vermis biometry with such a large sample size reported in literature. It is a detailed statistical survey and contains new centile-based reference charts for fetal height of cerebellar vermis measurements. PMID:26812238

OBJECTIVE: To determine the publication rate of orally-presented abstracts from the 2003 Urological Brazilian Meeting, as well as the factors determining this publication rate. MATERIALS AND METHODS: The publication rate of the 313 orally-presented abstracts at the 2003 Urological Brazilian Meeting was evaluated by scanning the Lilacs, Scielo and Medline databases. The time between presentation and publication, the state and country of the abstract, the research methodology (cross-sectional, case-control, retrospective case series, prospective case series or clinical trial), whether drugs were utilized and the topic of the study were all characterized. RESULTS: Thirty-nine percent of the abstracts were published after a median time of 14 months (range: 1 to 51 months). There were high publication rates for cross-sectional abstracts (75%), drug utilization studies (51.3%), clinical trials (50%) and prospective case series’ (48.1%). However, there was only a moderate statistical trend towards a higher publication rate in the prospective case series (p=0.07), while the retrospective case series’ showed statistically lower publication rates than the other groups (33.7%, p=0.04). Abstracts on laparoscopic surgery had the highest publication rate (61.9%, p=0.03) compared to others topics. In 57% of the unpublished abstracts, there was no interest in or attempt to publish, and rejection was responsible for the lack of publication of only 4% of the abstracts. CONCLUSION: The publication rate of the orally-presented abstracts from the 2003 Urological Brazilian Meeting was comparable to that of international congresses. The subsequent publication of presented abstracts and the selection of prospective studies with stronger evidence should be encouraged and may improve the scientific quality of the meeting.

Although positive effects of physical activity on mental health indicators have been reported, the relationship between physical activity and the development of specific mental disorders is unclear. A cross-sectional (12-month) and prospective-longitudinal epidemiological study over 4 years in a community cohort of 2548 individuals, aged 14-24 years at outset of the study. Physical activity and mental disorders were assessed by the DSM-IV Composite International Diagnostic Interview (CIDI) with an embedded physical activity module. Multiple logistic regression analyses controlling for age, gender and educational status were used to determine the cross-sectional and prospective associations of mental disorders and physical activity. Cross-sectionally, regular physical activity was associated with a decreased prevalence of any and co-morbid mental disorder, due to lower rates of substance use disorders, anxiety disorders and dysthymia. Prospectively, subjects with regular physical activity had a substantially lower overall incidence of any and co-morbid mental disorder, and also a lower incidence of anxiety, somatoform and dysthymic disorder. By contrast, the incidence of bipolar disorder was increased among those with regular physical activity at baseline. In terms of the population attributable fraction (PAF), the potential for preventive effects of physical activity was considerably higher for men than for women. Regular physical activity is associated with a substantially reduced risk for some, but not all, mental disorders and also seems to reduce the degree of co-morbidity. Further examination of the evidently complex mechanisms and pathways underlying these associations might reveal promising new research targets and procedures for targeted prevention.

Women previously giving birth with cesarean section have an increased risk of postpartum hemorrhage (PPH) and retained placenta. The objective of this study was to determine if anterior placental location increased the risk of PPH and retained placenta in such women. We performed a prospective cohort study on 400 women with cesarean section delivery in a previous pregnancy. Ultrasound examinations were performed at gestational week 28-30, and placental location, myometrial thickness, and three-dimensional vascularization index (VI) were recorded. Data on maternal age, parity, BMI, smoking, gestational week at delivery, induction, delivery mode, oxytocin, preeclampsia, PPH, retained placenta, and birth weight were obtained for all women. Outcome measures were PPH (≥1,000 mL) and retained placenta. The overall incidence of PPH was 11.0% and of retained placenta 3.5%. Twenty-three women (11.8%) with anterior placenta had PPH compared to 12 (6.9%) with posterior or fundal locations. The odds ratio was 1.94, but it did not reach statistical significance. There was no significant risk increase for retained placenta in women with anterior placentae. Seven of eight women with placenta previa had PPH, and four had retained placenta. The overall risk of PPH and retained placenta was high for women with previous cesarean section. Anterior location of the placenta in such women tended to impose an increased risk for PPH but no risk increase of retained placenta. Placenta previa in women with previous cesarean section is associated with a high risk for PPH and retained placenta.

Prospective design is mandatory to study pattern of poisoning and suicidal intention of patients. Prospective cross-sectional multi-center study of all patients contacting health care services because of acute poisoning during one year in Oslo, irrespective of intention. Data on the adult hospitalized patients (> or = 16 years) are presented here. Of a total of 3,775 such adult contacts (3,025 episodes), there were 947 (31 %) hospitalizations; annual incidence 1.9 (per 1,000) in males and 2.1 in females. Median age was 36 years (range 16-89); 54% females. Benzodiazepines (18%), ethanol (17%), paracetamol (12%), opioids (7%), and gamma hydroxybutyric acid (GHB) (7%) were most frequently taken. Patients stated suicidal intention in 29% of the admissions; physicians in 10%. Benzodiazepines and ethanol were the most common agents, but newer illicit drugs were frequent, especially GHB. Males often took ethanol and drugs of abuse; females often used prescription drugs with suicidal intention.

To compare the difference in risks of neonatal and maternal complications, including uterine rupture, in a second birth following a planned caesarean section versus emergency caesarean section in the first birth. Prospective cohort study. Population-based cohort in the Netherlands. Linked data set of outcomes for term caesarean section in a first birth followed by a consecutive delivery. We conducted a prospective cohort analysis using data from the Dutch Perinatal Registry. We included primiparous women who gave birth to term singleton infants through planned or emergency caesarean from January 2000 through December 2007, and who had a second singleton delivery during the same period (n = 41,109). Odds ratios and adjusted odds ratios were calculated. Maternal and neonatal complications, specifically uterine rupture, in second births associated with planned and emergency caesareans in the first birth. Women with a history of a planned caesarean section in the first birth (n = 11,445) had a 0.24% risk for uterine rupture, compared with a 0.16% risk for women with a history of emergency caesarean section (n = 29,664; aOR 1.4, 95% CI 0.8-2.4). In multivariate logistic regression, women with planned caesareans in a first birth had a significantly increased risk of stillbirth (aOR 1.5, 95% CI 1.0-2.2) and postpartum haemorrhage (aOR 1.1, 95% CI 1.0-1.2) in second births, compared with women with emergency caesareans in the first birth. We found a moderately increased risk of postpartum haemorrhage and a small to moderately increased risk of uterine rupture and stillbirth as a long-term effect of prior planned caesarean delivery on second births. © 2013 Royal College of Obstetricians and Gynaecologists.

The role of physical activity in producing and maintaining weight loss

PubMed Central

Catenacci, Victoria A; Wyatt, Holly R

2015-01-01

Summary The majority of randomized, controlled trials (RCTs) show only modest weight loss with exercise intervention alone, and slight increases in weight loss when exercise intervention is added to dietary restriction. In most RCTs, the energy deficit produced by the prescribed exercise is far smaller than that usually produced by dietary restriction. In prospective studies that prescribed high levels of exercise, enrolled individuals achieved substantially greater weight loss—comparable to that obtained after similar energy deficits were produced by caloric restriction. High levels of exercise might, however, be difficult for overweight or obese adults to achieve and sustain. RCTs examining exercise and its effect on weight-loss maintenance demonstrated mixed results; however, weight maintenance interventions were usually of limited duration and long-term adherence to exercise was problematic. Epidemiologic, cross-sectional, and prospective correlation studies suggest an essential role for physical activity in weight-loss maintenance, and post hoc analysis of prospective trials shows a clear dose–response relationship between physical activity and weight maintenance. This article reviews the role of physical activity in producing and maintaining weight loss. We focus on prospective, RCTs lasting at least 4 months; however, other prospective trials, meta-analyses and large systematic reviews are included. Limitations in the current body of literature are discussed. PMID:17581621

Two rural areas in Italy with different rates of pesticide usage were subjected to a cross-sectional investigation, based on the identification of organochlorine compounds in the environment and in human fatty tissues and on the determination of their concentration and a prospective investigation, based on the collection of data of past and present pathology and symptomatology from two stratified random groups of inhabitants of both areas. The cross-sectional investigation showed only small differences in environmental pollution and no differences in the storage of organochlorine compounds in fatty tissues in the two areas. The prospective investigation showed a higher prevalence of pathology and symptomatology in the population of the area where pesticides were used in larger quantities. Several haematochemical tests were used in an attempt to differentiate between populations at different levels of risk of toxic damage, but without success. PMID:5316616

A cross-sectional study is used to determine how rural New Mexico hospitals altered service diversification, inpatient service emphasis, and service promotion during Medicare's prospective payment system (PPS) transition and posttransition phases. Results suggest that the hospitals implemented distinct strategies in response to PPS. The posttransition strategies were examined for their association with improved revenue and utilization indicators. Few of the service diversification and promotional strategies were consistent predictors of performance. Emphasis on fine-tuning inpatient services was the most promising predictor of higher utilization and revenue measures. The implications for other rural hospitals are discussed.

The present study examined (both cross-sectionally and prospectively) the mediational role of college alcohol beliefs in the relationship between impulsivity-related traits and alcohol outcomes (i.e., alcohol use and negative consequences) among college student drinkers from the United States (U.S.), Spain, and Argentina. A sample of 1429 (U.S. = 733, Spain = 292, Argentina = 404) drinkers (at least one drinking episode within the previous month) completed the baseline survey, and 242 drinkers completed the follow-up. To test study aims, a cross-sectional model was first employed to examine whether the proposed double-mediated paths (i.e., each dimension of impulsivity → college alcohol beliefs → alcohol use → negative alcohol-related consequences) extends across samples with different cultural backgrounds (i.e., structural invariance testing). A longitudinal model was then conducted to assess if college alcohol beliefs prospectively mediate the associations between trait impulsivity and alcohol outcomes. College alcohol beliefs were concurrently and prospectively associated with both greater alcohol use and increased number of negative alcohol-related consequences. These internalized beliefs about college student drinking culture significantly mediated the effects of several distinct impulsivity-related traits on alcohol-related outcomes including urgency (positive and negative), sensation seeking, and perseverance. These findings were invariant across gender and across three countries (Argentina, Spain, and the U.S.). Our findings highlight the modulatory role of cognitive factors on problematic alcohol use among college students with different cultural backgrounds. Our results suggest that, despite the cultural differences exhibited by these three countries, the unique and mediational effects of college alcohol beliefs appear relatively universal.

Objective Women previously giving birth with cesarean section have an increased risk of postpartum hemorrhage (PPH) and retained placenta. The objective of this study was to determine if anterior placental location increased the risk of PPH and retained placenta in such women. Materials and methods We performed a prospective cohort study on 400 women with cesarean section delivery in a previous pregnancy. Ultrasound examinations were performed at gestational week 28–30, and placental location, myometrial thickness, and three-dimensional vascularization index (VI) were recorded. Data on maternal age, parity, BMI, smoking, gestational week at delivery, induction, delivery mode, oxytocin, preeclampsia, PPH, retained placenta, and birth weight were obtained for all women. Outcome measures were PPH (≥1,000 mL) and retained placenta. Results The overall incidence of PPH was 11.0% and of retained placenta 3.5%. Twenty-three women (11.8%) with anterior placenta had PPH compared to 12 (6.9%) with posterior or fundal locations. The odds ratio was 1.94, but it did not reach statistical significance. There was no significant risk increase for retained placenta in women with anterior placentae. Seven of eight women with placenta previa had PPH, and four had retained placenta. Conclusions The overall risk of PPH and retained placenta was high for women with previous cesarean section. Anterior location of the placenta in such women tended to impose an increased risk for PPH but no risk increase of retained placenta. Placenta previa in women with previous cesarean section is associated with a high risk for PPH and retained placenta. PMID:28826360

Introduction The influence of physical activity (PA) and physical fitness (PF) at older ages on changes in telomere length (TL), repetitive DNA sequences that may mark biologic aging, is not well-established. Few prior studies have been conducted in older adults, these were mainly cross-sectional, and few evaluated PF. Methods We investigated cross-sectional and prospective associations of PA and PF with leukocyte TL among 582 older adults (age 73±5 y at baseline) in the Cardiovascular Health Study, having serial TL measures and PA and PF assessed multiple times. Cross-sectional associations were assessed using multivariable repeated-measures regression, in which cumulatively averaged PA and PF measures were related to TL. Longitudinal analyses assessed cumulatively averaged PA and PF against later changes in TL; and changes in cumulatively averaged PA and PF against changes in TL. Results Cross-sectionally, greater walking distance and chair test performance, but not other PA and PF measures, were each associated with longer TL (p-trend=0.007, 0.04 respectively). In longitudinal analyses, no significant associations of baseline PA and PF with change in TL were observed. In contrast, changes in leisure-time activity and chair test performance were each inversely associated with changes in TL. Conclusions Cross-sectional analyses suggest that greater PA and PF are associated with longer TL. Prospective analyses show that changes in PA and PF are associated with differences in changes in TL. Even later in life, changes in certain PA and PF measures are associated with changes in TL, suggesting that leisure-time activity and fitness could reduce leukocyte telomere attrition among older adults.

Abstract Little is known about the association between iodine and human milk composition. In this study, we investigated the association between iodine and different markers of oxidative stress and obesity-related hormones in human breast milk. This work is composed of two cross-sectional studies (in lactating women and in the general population), one prospective and one in vitro. In the cross-sectional study in lactating women, the breast milk iodine correlated negatively with superoxide dismutase (SOD), catalase, and glutathione peroxidase (GSH-Px) activities, and with adiponectin levels. An in vitro culture of human adipocytes with 1 μM potassium iodide (KI, dose similar to the human breast milk iodine concentration) produced a significant decrease in adiponectin, GSH-Px, SOD1, and SOD2 mRNA expression. However, after 2 months of treatment with KI in the prospective study, a positive correlation was found between 24-h urinary iodine and serum adiponectin. Our observations lead to the hypothesis that iodine may be a factor directly involved in the regulation of oxidative stress and adiponectin levels in human breast milk. Antioxid.

Most of the knowledge on the prevailing dermoscopic patterns of acquired melanocytic nevi (AMV) is based on studies in Caucasians, while little research focuses on the dermoscopic variability in nevi in skin of colour. To analyse the prevalent dermoscopic nevus patterns in subjects with a skin type (ST) V and VI. Prospective, cross-sectional, morphological study was conducted in six clinics with enrolment of consecutive individuals with a ST V or VI. Digital dermoscopic images of selected representative AMN were assessed for dermoscopic colours, morphological patterns and pigment distribution. Analysis of 300 nevi from subjects with ST V and VI revealed significant differences in the nevus pattern between these two groups. The majority of nevi in ST V revealed a reticular pattern, whereas persons with ST VI more frequently exhibited a structureless pattern. Black, blue and grey were more frequent in ST VI, whereas the vast majority of nevi in ST V individuals showed dark brown colour. Our study provides new insights into the nevus pattern in individuals with a dark pigmentary trait, which may aid the diagnosis and management of nevi in this patients group. © 2013 European Academy of Dermatology and Venereology.

An association between plantar fasciitis and isolated gastrocnemius tightness (IGT) has been postulated in the literature; however, there have been few studies to prove this relationship. This prospective cross-sectional cohort study was aimed at determining the association between plantar fasciitis and IGT. Three groups comprising 45 patients with plantar fasciitis (group 1), 117 patients with foot and ankle pathology other than plantar fasciitis (group 2), and 61 patients without foot and ankle pathology (group 3) were examined for the presence of IGT using the Silfverskiöld test. Statistical tests included chi-square test, Student t test, and analysis of variance. Of the patients, 101 (45.3%) had IGT: 36 (80%) in group 1, 53 (45.3%) in group 2, and 12 (19.7%) in group 3. The difference in IGT prevalence between the groups was statistically significant at P < .001. The prevalence of IGT was similar between acute and chronic plantar fasciitis at 78.9% and 80.6%, respectively. There was a very strong association between plantar fasciitis and IGT using group 3 as a reference. This study suggests that IGT should be actively sought out and managed in patients with plantar fasciitis. Level II, cross-sectional cohort prospective study.

Objective To quantify the association between long working hours and alcohol use. Design Systematic review and meta-analysis of published studies and unpublished individual participant data. Data sources A systematic search of PubMed and Embase databases in April 2014 for published studies, supplemented with manual searches. Unpublished individual participant data were obtained from 27 additional studies. Review methods The search strategy was designed to retrieve cross sectional and prospective studies of the association between long working hours and alcohol use. Summary estimates were obtained with random effects meta-analysis. Sources of heterogeneity were examined with meta-regression. Results Cross sectional analysis was based on 61 studies representing 333 693 participants from 14 countries. Prospective analysis was based on 20 studies representing 100 602 participants from nine countries. The pooled maximum adjusted odds ratio for the association between long working hours and alcohol use was 1.11 (95% confidence interval 1.05 to 1.18) in the cross sectional analysis of published and unpublished data. Odds ratio of new onset risky alcohol use was 1.12 (1.04 to 1.20) in the analysis of prospective published and unpublished data. In the 18 studies with individual participant data it was possible to assess the European Union Working Time Directive, which recommends an upper limit of 48 hours a week. Odds ratios of new onset risky alcohol use for those working 49-54 hours and ≥55 hours a week were 1.13 (1.02 to 1.26; adjusted difference in incidence 0.8 percentage points) and 1.12 (1.01 to 1.25; adjusted difference in incidence 0.7 percentage points), respectively, compared with working standard 35-40 hours (incidence of new onset risky alcohol use 6.2%). There was no difference in these associations between men and women or by age or socioeconomic groups, geographical regions, sample type (population based v occupational cohort), prevalence of risky alcohol use in the cohort, or sample attrition rate. Conclusions Individuals whose working hours exceed standard recommendations are more likely to increase their alcohol use to levels that pose a health risk. PMID:25587065

Most studies rely on cross-sectional retrospective reports from adult samples to collect information about adverse childhood experiences (ACEs) to examine relationships with adult outcomes. The problems associated with these reports have long been debated, with only a few studies determining their reliability and validity and fewer still reaching consensus on the matter. This paper uses repeat prospective and retrospective reports of adverse childhood experiences from two respondent sources in the South African Birth to Twenty Plus (Bt20+) cohort to explore agreement and concordance in the prospective reporting of ACEs by caregivers and respective children as adolescents and then as young adults. The findings demonstrate little overall agreement between prospective and retrospective accounts of childhood experiences, with 80% of kappa values below the moderate agreement cutoff (k = .41). The highest levels of agreement were found between prospective and retrospective reporting on parental and household death (kappas ranging from .519 to .944). Comparisons between prospective caregiver reports and retrospective young adult reports yielded high concordance rates on sexual and physical abuse and exposure to intimate partner violence (91.0%, 87.7% and 80.2%, respectively). The prevalence of reported ACEs varied with the age of the respondent, with adolescents reporting much higher rates of exposure to violence, physical and sexual abuse than are reported retrospectively or by caregivers. This variation may partly reflect actual changes in circumstances with maturation, but may be influenced by developmental stage and issues of memory, cognition and emotional state more than has been considered in previous analyses. More research, across disciplines, is needed to understand these processes and their effect on recall. Long-term prospective studies are critical for this purpose. In conclusion, methodological research that uses a range of information sources to establish the reliability and validity of both retrospective and prospective reports ‒ recognizing that the two approaches may fundamentally answer different questions ‒ should be encouraged.

Cross-sectional designs are often used to monitor the proportion of infections and other post-surgical complications acquired in hospitals. However, conventional methods for estimating incidence proportions when applied to cross-sectional data may provide estimators that are highly biased, as cross-sectional designs tend to include a high proportion of patients with prolonged hospitalization. One common solution is to use sampling weights in the analysis, which adjust for the sampling bias inherent in a cross-sectional design. The current paper describes in detail a method to build weights for a national survey of post-surgical complications conducted in Israel. We use the weights to estimate the probability of surgical site infections following colon resection, and validate the results of the weighted analysis by comparing them with those obtained from a parallel study with a historically prospective design.

Little information is currently available concerning young medical students desire to pursue a career in oncology, or their career expectations. This project is a cross-sectional epidemiological study. A voluntary and anonymous questionnaire was distributed to all young oncologists studying in France between the 2nd of October 2013 and the 23rd of February 2014. The overall response rate was 75.6%. A total of 505 young oncologists completed the questionnaire. The main determining factors in the decision to practice oncology were the cross-sectional nature of the field (70.8%), the depth and variety of human relations (56.3%) and the multi-disciplinary field of work (50.2%). Most residents would like to complete a rotation outside of their assigned region (59.2%) or abroad (70.2%) in order to acquire additional expertise (67.7%). In addition, most interns would like to undertake a fellowship involving care, teaching and research in order to hone their skills (85.7%) and forge a career in public hospitals (46.4%). Career prospects mainly involve salaried positions in public hospitals. Many young oncologists are concerned about their professional future, due to the shortage of openings (40.8%), the workload (52.8%) and the lack of work-life balance (33.4%). This investigation provides a comprehensive profile of the reasons young oncologists chose to pursue a career in oncology, and their career prospects.

To evaluate the external cephalic version (ECV) procedure for the management of at term breech presenting fetuses. In this prospective, interventional study, 90 patients with uncomplicated breech presentations at or after 37 weeks' gestation were considered for ECV. This was performed in Al-Batool Teaching Hospital, Mosul, Iraq, between January 2011 and March 2012. The main outcome measure was assessed as the success rate of ECV attempt and the rate of cesarean section following a successful procedure. Parity, type of breech, placental location, and birth weight were evaluated as predictors of success. Also, any fetal or maternal complications during the procedure were evaluated. Data were analyzed by x2 test. Statistical significance was determined at a level of p<0.05. The success rate was 80%. The rate of cesarean section following successful procedure was only 12.5%. Prognostic parameters associated with successful ECV were multiparity and flexed type of breech. There were no serious fetal or maternal complications associated with the attempt. With appropriate selection of patients, ECV is highly successful and is a safer alternative to vaginal breech delivery or cesarean delivery.

Background/Aims Oxidative stress is involved in Alzheimer disease pathology, but its impact on cognitive function in community-dwelling older adults remains unknown. We estimated associations between serum oxidative stress markers and cognitive function in early old age. Methods Subjects aged 45-69 years recruited in urban centers in Central and Eastern Europe had memory, verbal fluency, and processing speed assessed at baseline (2002-2005) and 3 years later. Derivatives of reactive oxygen metabolites (d-ROMs), biological antioxidant potential (BAP), and total thiol levels (TTLs) were measured at baseline in a subsample. Linear regression was used to estimate associations of biomarkers with cognitive test scores cross-sectionally (n = 4,304) and prospectively (n = 2,882). Results Increased d-ROM levels were inversely associated with global cognition and verbal fluency cross-sectionally and in prospective analysis; observed effects corresponded to 3-4 years' higher age. TTL was inconsistently associated with memory. BAP was not related to cognitive function. Conclusion This study found modest evidence for a relationship between serum d-ROMs and cognitive function in a population sample of older adults. PMID:27802435

To examine associations of depressive feelings with disease-related variables and explore the moderating effect of social support on depressive feelings in individuals with early rheumatoid arthritis (RA) prospectively over 4 years. Data were collected annually over 4 years. The sample consisted of 124 individuals with diagnosed RA (85.5% women; mean age 47.9 years; mean disease duration 22.2 months). The strength of cross-sectional and prospective associations of sociodemographic, disease-related variables and the direct and moderating effects of social support on depression were tested using correlations, multilevel models, and hierarchical linear regressions. The study showed that emotional support moderated the influence of functional disability on depressive feelings in individuals with RA. This was not detected for instrumental support. Further prospective associations between functional status, marital status, and depressive feelings were also found. Overall, the strongest association was found between initial depressive feelings and depressive feelings over time. Initial depression seemed to be a risk factor in explaining later depressive feelings, but emotional support might be prospectively beneficial, especially for individuals with higher levels of disability. Early detection of individuals at risk for depression and providing interventions aimed at the specific functions of social support might help to decrease mental health problems.

Even though the association between thyroid dysfunction and anemia is commonly described, it is not known whether it is clinically relevant. This study set out to quantify the association of thyroid dysfunction on hemoglobin (Hb) concentration and risk of anemia. A systematic review (MEDLINE and EMBASE, from inception until May 15, 2017) was conducted to interpret the findings in context. Participants from the EPIC-Norfolk cohort with available baseline thyrotropin (TSH), free thyroxine (fT4), and Hb were included. Euthyroidism was defined as TSH 0.45-4.49 mIU/L (reference category), hypothyroidism as TSH ≥4.50 mIU/L (subclinical [SHypo] with normal fT4 or overt [OHypo] with low fT4), and hyperthyroidism as TSH ≤0.44 mIU/L (subclinical [SHyper] with normal fT4 or overt [OHyper] with elevated fT4). Anemia was defined as Hb <12 g/dL in women and Hb <13 g/dL in men. In the cross-sectional analyses, multiple linear regression was used to compare Hb across TSH categories. In the prospective analysis, participants with OHypo/OHyper at baseline were excluded, as it was assumed that they were treated for overt thyroid disease. A covariance model was used to determine change in Hb concentration from baseline to last follow-up, and multivariable Cox regression was used to analyze anemia risk. In the cross-sectional population (n = 12,337), the adjusted Hb was 0.22 g/dL lower [confidence interval (CI) 0.07-0.38] in OHypo compared to euthyroids, and 0.08 g/dL lower [CI -0.23 to 0.38] in OHyper. In the prospective analysis, 460/7031 participants developed anemia over a median follow-up of 4.7 years. The adjusted mean Hb change over time was -0.04 g/dL in SHypo [CI -0.14 to 0.06] and 0.05 g/dL in SHyper [CI -0.10 to 0.20]. The adjusted hazard ratio for anemia was 0.99 [CI 0.67-1.48] in SHypo, and 0.52 [CI 0.23-1.16] in SHyper. The systematic review returned no other prospective studies on this association, but cross-sectional and case-control studies showed comparable results. In this first prospective population-based cohort, subclinical thyroid dysfunction was not associated with a change in Hb concentration during follow-up and was not an independent risk factor for developing anemia; variations in Hb concentration in patients with overt thyroid dysfunction were not clinically relevant.

Proximity to Liquor Stores and Adolescent Alcohol Intake: A Prospective Study.

Trapp, Georgina S A; Knuiman, Matthew; Hooper, Paula; Foster, Sarah

2018-06-01

Cross-sectional studies have reported associations between liquor store availability and alcohol use among adolescents, but few prospective studies have confirmed this association. The aim of this study was to examine whether proximity to liquor stores at age 14 years was associated with alcohol intake at ages 14, 17, and 20 years. Participants of the Western Australian Pregnancy Cohort (Raine) Study (n=999) self-reported alcohol intake at age 14 years (early adolescence, 2003-2005); age 17 years (middle adolescence, 2006-2008); and age 20 years (late adolescence, 2009-2011). A GIS measured proximity to the closest liquor store from participants' home and school addresses at age 14 years. Regression analyses in 2017 assessed the relationship between distance to the closest liquor store around home, school, or both (≤800 m versus >800 m) and alcohol intake. In cross-sectional analyses (age 14 years), having a liquor store within 800 m of school was associated with ever having part of an alcoholic drink (OR=2.34, p=0.003). Also, having a liquor store within 800 m of home or school was associated with ever having part of an alcoholic drink (OR=1.49, p=0.029) and ever having engaged in heavy drinking (OR=1.79, p=0.023). In prospective analyses, liquor store proximity at age 14 years was a significant predictor of alcohol intake at age 17 years (OR=2.34, p=0.032) but not at age 20 years. Liquor store availability in early adolescence may be a risk factor for alcohol intake in early and middle, but not late, adolescence. Improved understanding of the longer-term impacts of liquor store exposure on sensitive populations could help inform future licensing regulations.

2014-07-01

The purpose of this work was to meta-analyze prospective studies that have evaluated the effect of a Mediterranean diet on the development of type 2 diabetes. PubMed, Embase and the Cochrane Central Register of Controlled Trials databases were searched up to 20 November 2013. English language publications were allocated; 17 original research studies (1 clinical trial, 9 prospective and 7 cross-sectional) were identified. Primary analyses were limited to prospective studies and clinical trials, yielding to a sample of 136,846 participants. A systematic review and a random effects meta-analysis were conducted. Higher adherence to the Mediterranean diet was associated with 23% reduced risk of developing type 2 diabetes (combined relative risk for upper versus lowest available centile: 0.77; 95% CI: 0.66, 0.89). Subgroup analyses based on region, health status of participants and number of confounders controlling for, showed similar results. Limitations include variations in Mediterranean diet adherence assessment tools, confounders' adjustment, duration of follow up and number of events with diabetes. The presented results are of major public health importance, since no consensus exists concerning the best anti-diabetic diet. Mediterranean diet could, if appropriately adjusted to reflect local food availability and individual's needs, constitute a beneficial nutritional choice for the primary prevention of diabetes.

The aim of this study was to explore the short-term effects of neuromuscular electrical stimulation application on tibialis anterior (stimulated muscle) and gastrocnemius (antagonist) muscles' size and architecture in children with cerebral palsy by using ultrasound. This prospective, controlled study included 28 children diagnosed with spastic diplegic cerebral palsy. Participants were treated either with neuromuscular electrical stimulation application and conventional physiotherapy (group A) or with conventional physiotherapy alone (group B). Outcome was evaluated by clinical (gross motor function, selective motor control, range of motion, spasticity) and ultrasonographic (cross-sectional area, pennation angle, fascicle length of tibialis anterior and gastrocnemius muscles) measurements before and after treatment in both groups. Cross-sectional area values of tibialis anterior (238.7 ± 61.5 vs. 282.0 ± 67.1 mm) and gastrocnemius (207.9 ± 48.0 vs. 229.5 ± 52.4 mm) (P < 0.001 and P = 0.008, respectively) muscles were increased after treatment in group A. Cross-sectional area values of tibialis anterior muscle were decreased (257.3 ± 64.7 vs. 239.7 ± 60.0 mm) after treatment in group B (P < 0.001), and the rest of the measurements were found not to have changed significantly in either group. These results have shown that cross-sectional area of both the agonist and antagonist muscles increased after 20 sessions of neuromuscular electrical stimulation treatment. Future studies with larger samples and longer follow-up are definitely awaited for better evaluation of neuromuscular electrical stimulation application on muscle architecture and its possible correlates in clinical/functional outcome.

Background Higher Lp-PLA2 activity is associated with increased risk of coronary heart disease (CHD), making Lp-PLA2 a potential therapeutic target. PLA2G7 variants associated with Lp-PLA2 activity could evaluate whether this relationship is causal. Methods and Results A meta-analysis including a total of 12 studies (5 prospective, 4 case-control, 1 case-only and 2 cross-sectional, n=26,118) was undertaken to examine the association of: (i) LpPLA2 activity vs. cardiovascular biomarkers and risk factors and CHD events (two prospective studies; n=4884); ii) PLA2G7 SNPs and Lp-PLA2 activity (3 prospective, 2 case-control, 2 cross-sectional studies; up to n=6094); and iii) PLA2G7 SNPs and angiographic coronary artery disease (2 case-control, 1 case-only study; n=4971 cases) and CHD events (5 prospective, 2 case-control studies; n=5523). Lp-PLA2 activity correlated with several CHD risk markers. Hazard ratio for CHD events top vs. bottom quartile of Lp-PLA2 activity was 1.61 (95%CI: 1.31, 1.99) and 1.17 (95%CI: 0.91, 1.51) after adjustment for baseline traits. Of seven SNPs, rs1051931 (A379V) showed the strongest association with Lp-PLA2 activity, VV subjects having 7.2% higher activity than AAs. Genotype was not associated with risk markers, angiographic coronary disease (OR 1.03 (95%CI 0.80, 1.32), or CHD events (OR 0.98 (95%CI 0.82, 1.17). Conclusions Unlike Lp-PLA2 activity, PLA2G7 variants associated with modest effects on Lp-PLA2 activity were not associated with cardiovascular risk markers, coronary atheroma or CHD. Larger association studies, identification of SNPs with larger effects, or randomised trials of specific Lp-PLA2 inhibitors are needed to confirm/refute a contributory role for Lp-PLA2 in CHD.

Loneliness has been repeatedly associated with sleep problems; however, there is a dearth of research examining the prospective relationship between insomnia and loneliness, as well as this association controlling for other psychiatric symptoms. This study evaluated the cross-sectional and prospective relationship between insomnia and loneliness using six samples: 666 undergraduates; 2785 Army recruiters; 208 adults with a history of suicidality and/or depression; 343 adult psychiatric outpatients; 326 young adults at elevated suicide risk; and 183 undergraduates. A meta-analysis also was conducted to examine the magnitude of the relationship between insomnia and loneliness across the six studies. More severe insomnia symptoms were significantly associated with greater feelings of loneliness while accounting for some (e.g., anxiety, nightmares) but not all (i.e., depression) psychiatric covariates. Findings underscore the strength of the association between insomnia and loneliness and suggest that depression may account for this relationship. Additional studies are needed to further establish the temporal relationship between these variables, delineate the role of depression in the association between insomnia and loneliness, and test whether insomnia may confer unique risk for subsequent loneliness.

The incidence of caesarean section for breech presentation has increased markedly in the last 20 years. A prospective, interventional cohort study was carried out of the success rate of external cephalic version (ECV) and its predictors of as well as its impact on the rate of caesarean section for vaginal breech delivery. All 128 women admitted during the study period to the obstetrics department of a tertiary care military hospital in Taif, Saudi Arabia with breech presentation at term, regardless of age and parity, who accepted ECV were recruited. ECV was successful in 53.9% of the women. Most of the women with successful ECV delivered normally (84.1%) and only 14.5% of them delivered by caesarean section. Conversely, normal vaginal delivery was reported among 8.5% of those who had spontaneous version with failed ECV and approximately two-thirds of them delivered by caesarean section (62.7%). Successful ECV reduced the breech and caesarean section rate.

The emergence of cerebral microbleeds (CMB) as common MR imaging findings raises the question of how MR imaging parameters influence CMB detection. To evaluate the effects of modified gradient recalled-echo (GRE) MR imaging methods, we performed an analysis of sequence, section thickness, and field strength on CMB imaging properties and detection in subjects with cerebral amyloid angiopathy (CAA), a condition associated with microhemorrhage. Multiple MR images were obtained from subjects with probable CAA, with varying sequences (GRE versus susceptibility-weighted imaging [SWI]), section thicknesses (1.2-1.5 versus 5 mm), and magnetic field strengths (1.5T versus 3T). Individual CMB were manually identified and analyzed for contrast index (lesion intensity normalized to normal-appearing white matter signal intensity) and diameter. CMB counts were compared between 1.5T thick-section GRE and thin-section SWI for 3 subjects who underwent both protocols in the same scanning session. With other parameters constant, use of SWI, thinner sections, and a higher field strength yielded medium-to-large gains in CMB contrast index (CI; Cohen d 0.71-1.87). SWI was also associated with small increases in CMB diameter (Cohen d <0.3). Conventional thick-section GRE identified only 33% of CMB (103 of 310) seen on thin-section SWI. Lesions prospectively identified on GRE had significantly greater CI and diameter measured on the GRE image than those not prospectively identified. The examined alternatives to conventional GRE MR imaging yield substantially improved CMB contrast and sensitivity for detection. Future studies based on these techniques will most likely yield even higher prevalence estimates for CMB.

To characterize postmarketing requirements for new drugs and biologics approved by the US Food and Drug Administration (FDA), and to examine rates and timeliness of registration, results reporting, and publication of required prospective cohort studies, registries, and clinical trials. Cross sectional analysis. Postmarketing requirements for all new drugs and biologics approved by the FDA between 1 January 2009 and 31 December 2012, with follow-up up to 15 November 2017. Postmarketing requirements and their characteristics known at the time of FDA approval, including FDA authority, study design, and study characteristics. Rates and timeliness of registration and results reporting on ClinicalTrials.gov and publication in peer reviewed journals of required prospective cohort studies, registries, and clinical trials. Between 2009 and 12, the FDA approved 97 new drugs and biologics for 106 indications with at least one postmarketing requirement at the time of first approval, for a total of 437 postmarketing requirements. Postmarket study descriptions were short (median word count 44 (interquartile range 29-71)) and often lacked information to determine an up to date progress (131 (30%)). 220 (50.3%) postmarketing requirements were for new animal or other studies (including pharmacokinetic studies); 134 (30.7%) were for prospective cohort studies, registries, and clinical trials; and 83 (19.0%) were for secondary analyses or follow-up studies. Of 110 clinical trials, 38 (34.5%), 44 (40.0%), 62 (56.4%), 66 (60.0%), and 98 (89.1%) did not report enough information to establish use of randomization, comparator type, allocation, outcome, and number of patients to be enrolled, respectively. Of 134 required prospective cohort studies, registries, and clinical trials, 102 (76.1%) were registered on ClinicalTrials.gov; of 50 registered and completed studies, 36 (72.0%) had reported results on ClinicalTrials.gov. Among 65 completed studies, 47 (72.3%) had either reported results or were published a median of 47 months (interquartile range 32-67) after FDA approval. 32 (68.1%) of these 47 studies did not report results publicly by the time of their original FDA report submission deadline. Postmarketing requirements for new drugs and biologics were often briefly described and did not contain enough information to characterize study designs. Approximately three quarters of postmarketing requirements for prospective cohort studies, registries, and clinical trials were registered on ClinicalTrials.gov, and nearly three quarters of completed studies reported results or were published, suggesting that at least a quarter of these required studies are not being publicly disseminated.

Cannabis is the most frequently used illicit drug worldwide. Cross-sectional neuroimaging studies suggest that chronic cannabis exposure and the development of cannabis use disorders may affect brain morphology. However, cross-sectional studies cannot make a conclusive distinction between cause and consequence and longitudinal neuroimaging studies are lacking. In this prospective study we investigate whether continued cannabis use and higher levels of cannabis exposure in young adults are associated with grey matter reductions. Heavy cannabis users (N = 20, age baseline M = 20.5, SD = 2.1) and non-cannabis using healthy controls (N = 22, age baseline M = 21.6, SD = 2.45) underwent a comprehensive psychological assessment and a T1- structural MRI scan at baseline and 3 years follow-up. Grey matter volumes (orbitofrontal cortex, anterior cingulate cortex, insula, striatum, thalamus, amygdala, hippocampus and cerebellum) were estimated using the software package SPM (VBM-8 module). Continued cannabis use did not have an effect on GM volume change at follow-up. Cross-sectional analyses at baseline and follow-up revealed consistent negative correlations between cannabis related problems and cannabis use (in grams) and regional GM volume of the left hippocampus, amygdala and superior temporal gyrus. These results suggests that small GM volumes in the medial temporal lobe are a risk factor for heavy cannabis use or that the effect of cannabis on GM reductions is limited to adolescence with no further damage of continued use after early adulthood. Long-term prospective studies starting in early adolescence are needed to reach final conclusions.

Many studies have reported that the prevalence of psychological distress among medical students during medical training was high. However, there are very few studies exploring on the psychological health of prospective medical students. This study aimed to determine the prevalence and associated factors for stress, anxiety and depression symptoms among the prospective medical students. A cross-sectional study was done on two cohorts of applicants to a public medical school. A total of 839 applicants were invited to participate in the study. The 21-item Depression Anxiety Stress Scale was administered to the applicants after they completed interviews. A total of 743 (92.2%) applicants took part in the study. The prevalence of moderate to extremely severe level of stress, anxiety and depression were 3.6%, 54.5% and 1.9%, respectively. Stress was significantly associated with extra-curricular activity (p<0.001) and race (p<0.001). Anxiety was associated with extra-curricular activity (p<0.001), race (p<0.001), mother education level (p=0.002) and CGPA group (p=0.034). Depression was associated with academic performance in class (p<0.001) and race (p=0.004). Prevalence of stress and depression among entering medical students was low; however prevalence of anxiety was high which could be due to worry about the interviews to enter medical course. The associated factors of psychological distress among prospective medical students were related to academic, non-academic, parent education and cultural backgrounds. Copyright © 2012 Elsevier B.V.

Television viewing, food preferences, and food habits among children: A prospective epidemiological study

PubMed Central

2011-01-01

Background Obesity has increased since the early 1980s, and despite numerous attempts, effective strategies to counter this worldwide epidemic are lacking. Food preferences are established early in life and are difficult to change later. There is therefore a need to identify factors that influence the development of food preferences. Our aim was therefore, to investigate cross-sectional and prospective associations between TV viewing habits and food preferences and habits, respectively. We hypothesized that more TV viewing was associated with less healthy concomitant and future food preferences and food habits. Methods Data are from the Danish part of European Youth Heart Study (EYHS) I and II, a prospective cohort study conducted among 8-10-year-old and 14-16-year-old Danes in 1997-98. Six years later 2003-04 the 8-10-year-olds were followed up at age 14-16 years, and a new group of 8-10-year olds were included. Data were analysed using mixed linear regression analysis. Cross-sectional analyses included 697 8-10-year-olds and 495 14-16-year-olds. Prospective analyses included 232 pupils with complete data at baseline and follow-up. Associations between TV viewing habits and the sum of healthy food preferences (ΣHFP), and the sum of healthy food habits (ΣHFH), respectively, were examined. Results Inverse cross-sectional associations between TV viewing (h/day) and both ΣHFP and ΣHFH were present for both the 8-10-year-old and the 14-16-year-old boys and girls. The frequency of meals in front of the TV (times/week) was also inversely associated with ΣHFP among 8-10-year-old boys, and with ΣHFH in all sex- and age groups. Among girls, baseline TV viewing (h/day) was directly associated with adverse development in the ΣHFP during follow-up. The concomitant 6-year changes in ΣHFH and TV viewing (h/day) were inversely associated in boys. Conclusions Long time spent on TV viewing, and possibly to a lesser degree, frequent consumption of meals during TV viewing, seem to be associated with generally having unhealthy food preferences and food habits among school-aged children. These associations, however, were not generally persistent after 6 years of follow-up. PMID:21569476

Built environmental attributes have been studied in relation to domestic time spent sedentary. An indoor behaviour has thus been linked to an outdoor setting. Yet, attributes of the actual domestic environment may also influence the time spent sedentary at home. Therefore, the aim was to examine if housing characteristics were cross-sectionally and prospectively related to leisure-time sitting in adults. In the Danish Health2006 cohort, 2308 adults were followed for 5 years. At baseline, subjects self-reported housing characteristics (habitat type, habitat surface area and household size), moderate-to-vigorous physical activity (MVPA) and socio-demographic factors. Leisure-time sitting was self-reported at baseline and 5-year follow-up. Multiple linear regression was used to assess cross-sectional and prospective associations. At baseline habitat surface area and household size were inversely associated with leisure-time sitting (p<0.01). Living in an apartment was associated with higher leisure-time sitting compared to living in a house (p<0.01). Household size was a predictor of 5-year leisure-time sitting (p<0.01), after adjustment for confounders and the other housing characteristics. Habitat type, habitat surface area and household size were associated with leisure-time sitting in adults, while especially household size was a predictor of leisure-time sitting five years later. The findings highlight the importance of home-environmental attributes when targeting a reduction in sedentary behaviours. Copyright © 2015 Elsevier Inc. All rights reserved.

Human immunodeficiency virus (HIV) causes impairment to the human immune system which leads to immunocompromised conditions, including ocular complications. Several important HIV-associated disorders may involve the anterior segment, ocular surface, and adnexae organ such as dry eye, blepharitis which reduce quality of life of patients. In present, potent antiretroviral therapies HAART (highly active antiretroviral therapy) has improved the length and quality of life which may lead to an increased prevalence of anterior segment ocular disorders. Hence, this study has been undertaken to identify the prevalence and associated factors of anterior segment and external ocular disorder in HIV infected patients in the era of HAART. A prospective descriptive cross sectional study was carried out in HIV positive patients conducted at the Department of Ophthalmology, Chiang Mai University Hospital, from February 2014 to October 2015. Detail history and ocular examination was carried out to examine for anterior segment and external ocular disorders. A total number of 363 patients were included for this prospective cross-sectional study. From the total of 363 patients, 123 patients had an anterior segment and external ocular disorder which account as the prevalence of 33.9%. The most common anterior segment manifestations was dry eye seen in 36 patients (9.9%), followed by posterior blepharitis (Meibomian gland dysfunction) seen in 23 patients (6.3%) and anterior blepharitis seen in 12 patients (3.3%). Other ocular complications included microvasculopathy, immune recovery uveitis, conjunctivitis, papilloma, anterior uveitis, corneal ulcer, nevus, trichiasis, molluscum contangiosum, Kaposi sarcoma, interstitial keratitis, conjunctival lymphangiectasia, dacryocystitis, vernal keratoconjunctivitis and eyelid penicilosis. In this study, the prevalance of anterior segment disorders was higher than in the preHAART era. Dry eye, blepharitis and uveitis were the top three most common anterior segment disorders in the HAART era. The statistical analysis showed no association between age, sex, CD4 count, duration of infection or receiving HAART and anterior segment disorders. Anterior segment abnormalities reduce the quality of life of patients, so ophthalmologists have to be aware and complete ocular examination should be performed in all HIV infected patients.

Caesarean section (CS) is often a life-saving procedure, but can also lead to serious complications, even more so in low-resource settings. Therefore unnecessary CS should be avoided and optimal circumstances for vaginal delivery should be created. In this study, we aim to audit indications for Caesarean sections and improve decision-making and obstetric management. Audit of all cases of CS performed from January to August 2013 was performed in a rural referral hospital in Tanzania. The study period was divided in three audit blocks; retrospective (before auditing), prospective 1 and prospective 2. A local audit panel (LP) and an external auditor (EA) judged if obstetric management was adequate and indications were appropriate or if CS could have been prevented and yet retain good pregnancy outcome. Furthermore, changes in modes of deliveries, overall pregnancy outcome and decision-to-delivery interval were monitored. During the study period there were 1868 deliveries. Of these, 403 (21.6%) were Caesarean sections. The proportions of unjustified CS prior to introduction of audit were as high as 34 and 75%, according to the respective judgments of LP and EA. Following introduction of audit, the proportions of unjustified CS decreased to 23% (p = 0.29) and 52% (p = 0.01) according to LP and EA respectively. However, CS rate did not change (20.2 to 21.7%), assisted vacuum delivery rate did not increase (3.9 to 1.8%) and median decision-to-delivery interval was 83 min (range 10 - 390 min). Although this is a single center study, these findings suggest that unnecessary Caesarean sections exist at an alarming rate even in referral hospitals and suggest that a vast number can be averted by introducing a focused CS audit system. Our findings indicate that CS audit is a useful tool and, if well implemented, can enhance rational use of resources, improve decision-making and harmonise practice among care providers.

Context: Both subclinical thyroid dysfunction and frailty are common among older individuals, but data on the relationship between these 2 conditions are conflicting. Objective: The purpose of this study was to assess the cross-sectional and prospective associations between subclinical thyroid dysfunction and frailty and the 5 frailty subdomains (sarcopenia, weakness, slowness, exhaustion, and low activity). Setting and Design: The Osteoporotic Fractures in Men Study is a prospective cohort study. Participants: Men older than 65 years (n = 1455) were classified into 3 groups of thyroid status: subclinical hyperthyroidism (n = 26, 1.8%), subclinical hypothyroidism (n = 102, 7.0%), and euthyroidism (n = 1327, 91.2%). Main Outcome Measures: Frailty was defined using a slightly modified Cardiovascular Health Study Index: men with 3 or more criteria were considered frail, men with 1 to 2 criteria were considered intermediately frail, and men with no criteria were considered robust. We assessed the cross-sectional relationship between baseline thyroid function and the 3 categories of frailty status (robust/intermediate/frail) as well as the prospective association between baseline thyroid function and subsequent frailty status and mortality after a 5-year follow-up. Results: At baseline, compared with euthyroid participants, men with subclinical hyperthyroidism had an increased likelihood of greater frailty status (adjusted odds ratio, 2.48; 95% confidence interval, 1.15–5.34), particularly among men aged <74 years at baseline (odds ratio for frailty, 3.63; 95% confidence interval, 1.21–10.88). After 5 years of follow-up, baseline subclinical hypothyroidism and hyperthyroidism were not consistently associated with overall frailty status or frailty components. Conclusion: Among community-dwelling older men, subclinical hyperthyroidism, but not subclinical hypothyroidism, is associated with increased odds of prevalent but not incident frailty.

The Mediterranean diet and age-related cognitive functioning: A systematic review of study findings and neuropsychological assessment methodology.

Knight, Alissa; Bryan, Janet; Murphy, Karen

2017-10-01

The primary aims of this review were to identify studies investigating the association between the MedDiet pattern and age-related cognitive function, to determine the current status of knowledge, and to ascertain whether a lack of standardization with the operationalization of age-related cognitive function and differences in the chosen neuropsychological assessment methodology impacted on the results and findings. The systematic review protocol for this paper was carried out following the statement and general principles of PRISMA and the UK Centre for Reviews and Dissemination (CRD). A systematic search of electronic databases yielded two cross-sectional studies, two cross-sectional/prospective studies, and 11 prospective studies for inclusion. Among this group of studies, conflicting results and conclusions regarding the efficacy of the MedDiet as a therapeutic approach for age-related cognitive function were found. Of importance, clear differences among studies in relation to neuropsychological assessment methodology were identified. Such disparity appeared to be one plausible factor contributing to the lack of consensus among study findings. One of the important challenges for future research will be to aim toward some kind of standardized neuropsychological assessment criteria. This type of endeavor will enable the ability to validate with greater confidence, whether or not adherence to a MedDiet does promote benefit for age-related cognitive function.

Bias Due to Correlation Between Times-at-Risk for Infection in Epidemiologic Studies Measuring Biological Interactions Between Sexually Transmitted Infections: A Case Study Using Human Papillomavirus Type Interactions

PubMed Central

2016-01-01

The clustering of human papillomavirus (HPV) infections in some individuals is often interpreted as the result of common risk factors rather than biological interactions between different types of HPV. The intraindividual correlation between times-at-risk for all HPV infections is not generally considered in the analysis of epidemiologic studies. We used a deterministic transmission model to simulate cross-sectional and prospective epidemiologic studies measuring associations between 2 HPV types. When we assumed no interactions, the model predicted that studies would estimate odds ratios and incidence rate ratios greater than 1 between HPV types even after complete adjustment for sexual behavior. We demonstrated that this residual association is due to correlation between the times-at-risk for different HPV types, where individuals become concurrently at risk for all of their partners’ HPV types when they enter a partnership and are not at risk when they are single. This correlation can be controlled in prospective studies by restricting analyses to susceptible individuals with an infected sexual partner. The bias in the measured associations was largest in low-sexual-activity populations, cross-sectional studies, and studies which evaluated infection with a first HPV type as the exposure. These results suggest that current epidemiologic evidence does not preclude the existence of competitive biological interactions between HPV types. PMID:27927619

Glagov proposed that remodeling delayed development of significant coronary artery stenoses until plaque occupied, on average, 40% of arterial area (40% plaque burden). The aim of the current study was to confirm the previously proposed concept of coronary remodeling as first described by Glagov who studied postmortem left main coronary arteries (LMCAs). Using the in-vivo intravascular ultrasound data from the Providing Regional Observations to Study Predictors of Events in the Coronary Tree (PROSPECT) study, we evaluated 552 LMCAs in 552 patients. External elastic membrane cross-sectional areas (CSAs) increased in proportion to the increase in plaque and media CSAs (r=0.61, P<0.0001), especially when the plaque burden was 20% or lower (r=0.88, P<0.0001). For more advanced atherosclerosis (>40% plaque burden), there was an inverse relationship between lumen CSA and plaque burden (r=-0.57, P<0.0001), whereas this relationship was weak in the presence of less than 40% plaque burden. The frequency of virtual histology derived thin-cap fibroatheroma increased with increasing plaque burden. In contrast, the frequency of pathological intimal thickening decreased. The previously proposed remodeling concept of Glagov was validated in vivo in the PROSPECT study patients. In addition, the present study suggested that plaque phenotype worsened with increasing LMCA plaque growth.

Antibacterial drugs (hereafter referred to as antibiotics) are crucial to treat infections during delivery and postpartum period to reduce maternal mortality. Institutional deliveries have the potential to save lives of many women but extensive use of antibiotics, add to the development and spread of antibiotic resistance. The aim of this study was to present antibiotic prescribing among inpatients during and after delivery in a non-teaching, tertiary care hospital in the city of Ujjain, Madhya Pradesh, India. A prospective cross-sectional study was conducted including women having had either a vaginal delivery or a cesarean section in the hospital. Trained nursing staff collected the data on daily bases, using a specific form attached to each patient file. Statistical analysis, including bivariate and multivariable logistic regression was conducted. Of the total 1077 women, 566 (53%) had a vaginal delivery and 511 (47%) had a cesarean section. Eighty-seven percent of the women that had a vaginal delivery and 98% of the women having a cesarean section were prescribed antibiotics. The mean number of days on antibiotics in hospital for the women with a vaginal delivery was 3.1 (±1.7) and for the women with cesarean section was 6.0 (±2.5). Twenty-eight percent of both the women with vaginal deliveries and the women with cesarean sections were prescribed antibiotics at discharge. The most commonly prescribed antibiotic group in the hospital for both the women that had a vaginal delivery and the women that had a cesarean section were third-generation cephalosporins (J01DD). The total number of defined daily doses (DDD) per100 bed days for women that had a vaginal delivery was 101, and 127 for women that had a cesarean section. The high percentage of women having had a vaginal delivery that received antibiotics and the deviation from recommendation for cesarean section in the hospital is a cause of concern. Improved maternal health and rational use of antibiotics are intertwined. Specific policy and guidelines on how to prescribe antibiotics during delivery at health care facilities are needed. Additionally, monitoring system of antibiotic prescribing and resistance needs to be developed and implemented.

Discrimination and alcohol-related problems among college students: a prospective examination of mediating effects.

Hatzenbuehler, Mark L; Corbin, William R; Fromme, Kim

2011-06-01

Discrimination is a risk factor for health-risk behaviors, including alcohol abuse. Far less is known about the mechanisms through which discrimination leads to alcohol-related problems, particularly during high-risk developmental periods such as young adulthood. The present study tested a mediation model using prospective data from a large, diverse sample of 1539 college students. This model hypothesized that discrimination would be associated with established cognitive (positive alcohol expectancies) and affective (negative affect and coping motives) risk factors for alcohol-related problems, which would account for the prospective association between discrimination and alcohol problems. Structural equation modeling indicated that discrimination was associated cross-sectionally with negative affect and more coping motives for drinking, but not with greater alcohol expectancies. Coping motives mediated the prospective relationship between discrimination and alcohol-related problems. Additionally, results indicated significant indirect effects from discrimination to alcohol-related problems through negative affect and coping motives. These associations were evident for multiple groups confronting status-based discrimination, including women, racial/ethnic minorities, and lesbian/gay/bisexual individuals. This study identified potential affective mechanisms linking discrimination to alcohol-related problems. Results suggest several avenues for prevention and intervention efforts with individuals from socially disadvantaged groups. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Medicare program; prospective payment system for hospital outpatient services--HCFA. Proposed rule.

PubMed

1998-09-08

As required by sections 4521, 4522, and 4523 of the Balanced Budget Act of 1997, this proposed rule would eliminate the formula-driven overpayment for certain outpatient hospital services, extend reductions in payment for costs of hospital outpatient services, and establish in regulations a prospective payment system for hospital outpatient services (and for Medicare Part B services furnished to inpatients who have no Part A coverage). The prospective payment system would simplify our current payment system and apply to all hospitals, including those that are excluded from the inpatient prospective payment system. The Balanced Budget Act provides for implementation of the prospective payment system effective January 1, 1999, but delays application of the system to cancer hospitals until January 1, 2000. The hospital outpatient prospective payment system would also apply to partial hospitalization services furnished by community mental health centers. Although the statutory effective date for the outpatient prospective payment system is January 1, 1999, implementation of the new system will have to be delayed because of year 2000 systems concerns. The demands on intermediary bill processing systems and HCFA internal systems to become compliant for the year 2000 preclude making the major systems changes that are required to implement the prospective payment system. The outpatient prospective payment system will be implemented for all hospitals and community mental health centers as soon as possible after January 1, 2000, and a notice of the anticipated implementation date will be published in the Federal Register at least 90 days in advance. This document also proposes new requirements for provider departments and provider-based entities. These proposed changes, as revised based on our consideration of public comments, will be effective 30 days after publication of a final rule. This proposed rule would also implement section 9343(c) of the Omnibus Budget Reconciliation Act of 1986, which prohibits Medicare payment for nonphysician services furnished to a hospital outpatient by a provider or supplier other than a hospital, unless the services are furnished under an arrangement with the hospital. This section also authorizes the Department of Health and Human Services' Office of Inspector General to impose a civil money penalty, not to exceed $10,000, against any individual or entity who knowingly and willfully presents a bill for nonphysician or other bundled services not provided directly or under such an arrangement. This proposed rule also addresses the requirements for designating certain entities as provider-based or as a department of a hospital.

2015-07-01

The ideal lip augmentation technique provides the longest period of efficacy, lowest complication rate, and best aesthetic results. A myriad of techniques have been described for lip augmentation, but the optimal approach has not yet been established. This systematic review with meta-regression will focus on the various filling procedures for lip augmentation (FPLA), with the goal of determining the optimal approach. A systematic search for all English, French, Spanish, German, Italian, Portuguese and Dutch language studies involving FPLA was performed using these databases: Elsevier Science Direct, PubMed, Highwire Press, Springer Standard Collection, SAGE, DOAJ, Sweetswise, Free E-Journals, Ovid Lippincott Williams & Wilkins, Willey Online Library Journals, and Cochrane Plus. The reference section of every study selected through this database search was subsequently examined to identify additional relevant studies. The database search yielded 29 studies. Nine more studies were retrieved from the reference sections of these 29 studies. The level of evidence ratings of these 38 studies were as follows: level Ib, four studies; level IIb, four studies; level IIIb, one study; and level IV, 29 studies. Ten studies were prospective. This systematic review sought to highlight all the quality data currently available regarding FPLA. Because of the considerable diversity of procedures, no definitive comparisons or conclusions were possible. Additional prospective studies and clinical trials are required to more conclusively determine the most appropriate approach for this procedure. IV.

Is Positive Emotionality a Specific Risk Factor for Depression? A Meta-Analysis of Longitudinal Studies

PubMed Central

Khazanov, Gabriela Kattan; Ruscio, Ayelet Meron

2016-01-01

Depression is well known to share a negative cross-sectional relationship with personality constructs defined by positive emotion (positive affect, extraversion, behavioral activation). These Positive Emotionality (PE) constructs have been proposed to represent stable temperamental risk factors for depression, not merely current mood state. These constructs have also been proposed to increase risk specifically for depression, relative to anxiety. We performed a meta-analysis of longitudinal studies to examine the relationship of PE to depression (59 effect sizes) and anxiety (26 effect sizes). In cross-sectional analyses, PE constructs were negatively associated with depression (r = −.34) and anxiety (r = −.24). PE constructs also prospectively predicted depression (r = −.26) and anxiety (r = −.19). These relationships remained statistically significant, but were markedly attenuated, when baseline levels of depression (β = −.08) and anxiety (β = −.06) were controlled. Moreover, depression and anxiety were equally strong predictors of subsequent changes in PE (β = −.07 and −.09, respectively). These findings are consistent with theoretical accounts of low PE as a temperamental vulnerability for depression, but suggest that the prospective relationship of PE to depression may be weaker and less specific than previously assumed.

The aims of this study were to evaluate seroprevalence and the importance of various risk-factors for Toxoplasma infection in the Czech Republic. A prospective cross-sectional survey was conducted among military personnel in Prague. Consenting subjects (n = 3250) completed a questionnaire concerning demographics and risk-factors, and blood samples were taken to determine anti-Toxoplasma antibody titres according to complement fixation and ELISA IgG and IgM tests. The seroprevalence of toxoplasmosis was 23%. In multivariate analysis, independent predictors of Toxoplasma seropositivity were age (OR 1.03 / year), consumption of raw meat (OR 1.35), owning a cat (OR 1.25), owning rabbits (OR 1.47), childhood residence in a town with a population of <10 000 inhabitants (OR 1.63) vs. location of the childhood residence in a town with population of >100 000 inhabitants, and blood group type A (OR 1.28), B (OR 1.33) or AB (OR 1.43) vs. O. These results suggested that horizontal toxoplasmosis transmission in the Czech Republic may occur through consumption of raw meat, contact with cat faeces and farming.

Serum cardiac troponin T and effective blood flow in stable extracorporeal dialysis patients.

2016-03-01

We examined the association between extracorporeal dialysis (ED)-related effective blood flow (eQB) and serum cardiac troponin T (cTnT) as a possible indicator of silent myocardial damage in stable ED patients. In a cross-sectional study, cTnT was determined in 247 ED patients dialyzed using stable eQB and dialysate flow (QD). In a prospective study, 91 patients were switched from low-flux (LF) to high-flux (HF) hemodialysis (HD), and subsequently, the eQB increased, and the QD decreased; 65 patients continued LF-HD with stable eQB and QD. Clinical/laboratory evaluations were performed at 0, 15, 36, and 53 weeks from the start of the study. In the cross-sectional study, the main cTnT predictors were dialysis vintage, age, eQB, phosphorus, and C-reactive protein. Patients with cTnT levels in the highest quartile were excluded from the analysis, and subjects dialyzed with eQB ≤316 ml/min exhibited lower cTnT levels compared with patients dialyzed with higher eQB (P = 0.002). The all-cause and cardiac mortality rates of 154 patients, without changes in ED modality for up to 42 months, were associated with the initial cTnT concentrations but not with the initial eQB. In the prospective study, higher values for eQB and cTnT were observed during HF-HD at weeks 36 (P = 0.045) and 53 (P = 0.01) of the present study. The initial cTnT, ∆eQB, and ∆albumin influenced the ∆cTnT. The all-cause and cardiac mortality rates were not different between LF and HF groups at 21 months after the prospective study was completed. In stable ED patients, higher eQB rates and QB/QD values might contribute to silent myocardial injury, particularly in patients with lower cTnT levels, but do not affect the outcome of ED patients.

We are also consolidating, clarifying, and revising existing policies regarding IRF hospitals and IRF units of hospitals to eliminate unnecessary confusion and enhance consistency. Furthermore, in accordance with the general principles of the President's January 18, 2011 Executive Order entitled ``Improving Regulation and Regulatory Review,'' we are amending existing regulatory provisions regarding ''new'' facilities and changes in the bed size and square footage of IRFs and inpatient psychiatric facilities (IPFs) to improve clarity and remove obsolete material.

Home feeding environment and picky eating behavior in preschool-aged children: A prospective analysis.

PubMed

Cole, Natasha Chong; Musaad, Salma M; Lee, Soo-Yeun; Donovan, Sharon M

2018-06-07

Picky eating is prevalent in young children and is associated with poor dietary quality and nutrient deficiencies. Identifying predictors of picky eating could inform the development of anticipatory feeding guidance for parents and caregivers of young children. This study identified the association between factors of the home feeding environment with picky eating behavior in a cohort of preschool-aged children. Parents of preschool-aged children (n = 497) completed questionnaires including measures of the home feeding environment (i.e., television during mealtime, family mealtime routines, and feeding practices) and child picky eating behavior. The questionnaire was repeated one year later, in which 326 parent-child dyads participated. Logistic regression was used to determine the cross-sectional and prospective associations between home feeding environment measures and child picky eating behavior outcomes. Child control over feeding and watching television during mealtime were associated with higher odds of picky eating behavior in both cross-sectional and prospective analyses. A higher sense of positive climate during family meals and mealtime ritualization was associated with lower odds of picky eating behavior one year later. The home feeding environment plays a role in the development of young children's picky eating behavior. Avoiding the television and maintaining parent control of food choices during mealtimes could lead to improvements in children's food preferences and dietary intake. Copyright © 2018.

Current health and preferences for life-prolonging treatments: an application of prospect theory to end-of-life decision making.

PubMed

Winter, Laraine; Parker, Barbara

2007-10-01

As a substantial body of research attests, the acceptability of life-prolonging treatment (e.g., tube feeding) tends to be greater among people in worse health than among healthier ones. Because a decision for or against a life-prolonging treatment represents a choice between two prospects-life (usually in poor health) and death-we propose a decision model, Prospect Theory, as a theoretical account of this phenomenon. Prospect Theory postulates that pairs of distant prospects are less distinguishable than pairs of closer ones. Thus, to healthy individuals, the prospects of death and life in poor health would both be remote, and therefore, the distinction between them, small. To less healthy individuals, however, the difference between the same pairs of prospects would appear greater, and therefore, life-prolonging treatment may be more acceptable. In a cross-sectional study of 304 community-dwelling people, aged 60 years and over in the Philadelphia area, USA, preferences for 4 life-prolonging treatments in 9 health scenarios were examined in relation to participants' current health, operationalized as number of deficits in physical functioning. As predicted, less healthy people expressed stronger preferences for all life-prolonging treatments compared with healthier ones, with differences greatest in the worse-health scenarios. Preferences also varied by health scenario, with any treatment preferred in the better health scenarios. Treatment preferences did not differ by type of treatment, depressed mood or any demographic characteristic except race, with African-Americans expressing stronger treatment preferences. Implications for advance care planning are discussed.

Prospecting for Natural Gas Gydrate in the Orca & Choctaw Basins in the Northern Gulf of Mexico

The Orca and Choctaw salt bounded mini-basins, which occur in 1.5 to 2.5 km water depth on the northern Gulf of Mexico slope, are currently under consideration as an IODP scientific drilling location for coarse-grained natural gas hydrate systems. We use a 3D seismic dataset for gas hydrate prospecting that covers parts of eleven lease blocks ( 200 km2) in the Walker Ridge protraction area. The study area includes the southern section of the Orca Basin and a smaller section of the northern Choctaw Basin. We have mapped a discontinuous bottom-simulating reflection (BSR) over nearly 30% of our seismic dataset, which varies significantly in both amplitude and depth throughout the area. The southeastern section of our dataset contains three positive impedance amplitude horizons with possible phase reversals at the BSR. Detailed mapping in the area also reveals at the base of gas hydrate stability, a complicated intercalation of an east-west trending fault system and an amalgamated deepwater depositional system comprising channel levee deposits and turbidite sheet sands. Three industry wells drilled in the southwestern section of our study area indicate that the sedimentary sequence infilling the basins consists of predominantly mud rich units with interbedded turbidite sands, forming a 2 km thick supra-salt sequence of late Miocene to Pleistocene sediments. Two of the industry wells have strong evidence for natural gas hydrate in clay-rich sediment, with moderate resistivity (between 2-10 Ωm) increases above background resistivity in zones that exceed 60 m thick. Additionally, the electromagnetic resistivity curves in these wells separate suggesting that the gas hydrate occurs in high-angle fractures. We will present our seismic dataset, our continuing analysis and selected drill sites in the Orca and Choctaw basins. Furthermore, our analysis in the southeastern section of the study area underscores the importance of interpreting faults when considering phase reversals in hydrate systems.

Adolescent suicide rates (ASR) are a matter of concern worldwide. Causes of this trend are not understood and could correspond to socioeconomic factors such as inequality. To investigate sociodemographic variables related to ASR, particularly the potential association with indicators of socioeconomic inequality. Cross-sectional ecological study analyzing data from 29 health districts with univariate and multivariable multilevel Poisson models. ASR were higher in male adolescents and at increasing age. No association was found between ASR and inequality (Gini coefficient and 20/20 ratio). Analysis revealed that living in a single-parent family is associated with ASR. The usual demographic patterns of adolescent suicide apply in Chile. An emerging variable of interest is single-parent family. No cross-sectional association between social inequality and ASR was found based on conflicting evidence. These results should be explored in future prospective population studies to further understand associated social factors.

To investigate the impact of early cleavage (EC) on embryo quality, implantation, and live-birth rates. Prospective cross-sectional study. Multicenter study. Seven hundred embryo transfers and 1,028 early-stage human embryos. None. Implantation according to the presence of EC and embryo quality. The presence of EC is associated with embryo quality, especially in cycles with autologous oocytes. However, the use of EC as an additional criterion for selecting an embryo for transfer does not appear to significantly improve likelihood of implantation. Furthermore, embryos that presented EC had live-birth rates per implanted embryo similar to those that did not show any sign of cleavage. At least for conventional embryo culture and morphologic evaluations, the additional evaluation of EC in embryos may not be valuable to improve embryo implantation.

2016-05-01

Studies conducted on hospice volunteers' characteristics and experiences have been cross-sectional. We conducted a prospective study to examine changes in the volunteer experience over time in a cohort of volunteers during the first year of a new residential hospice. Eighty-two active volunteers completed an online baseline survey, and of these, 39 completed a follow-up survey at 6 months. The survey included measures of motivations to volunteer, satisfaction with role and with the organization, and fear of death and dying. Repeated measures analyses indicated that motivations to volunteer remained stable over time while volunteer satisfaction increased with time. Baseline level of fears of death and dying varied by age, volunteer role, and motivations to volunteer and decreased at 6 months. Volunteering in a residential hospice tends to be a satisfying experience that helps to allay fears about death and dying. © The Author(s) 2014.

What about the Misgav-Ladach surgical technique in patients with previous cesarean sections?

PubMed

Bolze, Pierre-Adrien; Massoud, Mona; Gaucherand, Pascal; Doret, Muriel

2013-03-01

The Misgav-Ladach technique is recommended worldwide to perform cesarean sections but there is no consensus about the appropriate technique to use in patients with previous cesarean sections. This study evaluated the feasibility of the Misgav-Ladach technique in patients with previous cesarean sections. This prospective cohort study included all women undergoing cesarean section after 36 weeks of gestation over a 5-month period, with the Misgav-Ladach technique as first choice, whatever the previous number of cesarean sections. Among the 204 patients included, the Misgav-Ladach technique was successful in 100%, 80%, and 65.6% of patients with no, one, and multiple previous cesarean sections, respectively. When successful, the Misgav-Ladach technique was associated with a shorter incision to birth interval in patients with no previous cesarean section compared with patients with one or multiple previous cesarean sections. Anterior rectus aponeurosis fibrosis and severe peritoneal adherences were the two main reasons explaining the Misgav-Ladach technique failure. The Misgav-Ladach technique is possible in over three-fourths of patients with previous cesarean sections with a slight increase in incision to birth interval compared with patients without previous cesarean section. Further studies comparing the Misgav-Ladach and the Pfannenstiel techniques in women with previous cesarean should be done. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

2017-10-01

Several cross-sectional studies have linked different environmental contaminants to the metabolic syndrome (MetS). However, mixture effects have not been investigated and no prospective studies exist regarding environmental contaminants and the MetS. To study mixture effects of contaminants on the risk of incident MetS in a prospective fashion. Our sample consisted of 452 subjects from the Prospective Study of the Vasculature in Uppsala Seniors (PIVUS) study (50% women, all aged 70years) free from the MetS at baseline, being followed for 10years. At baseline, 30 different environmental contaminants were measured; 6 polychlorinated biphenyls (PCBs), 3 organochlorine (OC) pesticides, one dioxin, one polybrominated diphenyl ether (all in plasma), 8 perfluoroalkyl substances (in plasma) and 11 metals (in whole blood). The MetS was defined by the ATPIII/NCEP criteria. Gradient boosted Classification and Regression Trees (CARTs) was used to evaluate potential synergistic and additive mixture effects on incident MetS. During 10-year follow-up, 92 incident cases of the MetS occurred. PCB126, PCB170, hexachlorobenzene (HCB) and PCB118 levels were all associated with incident MetS in an additive fashion (OR 1.73 for a change from 10th to 90th percentile (95%CI 1.24-3.04) for PCB126, OR 0.63 (0.42-0.78) for PCB170, OR 1.44 (1.09-2.20) for HCB and OR 1.46 (1.13-2.43) for PCB118). No synergistic effects were found. A mixture of environmental contaminants, with PCB126, PCB170, HCB and PCB118 being the most important, showed associations with future development of the MetS in an additive fashion in this prospective study. Thus, mixture effects of environmental contaminants could contribute to the development of cardio-metabolic derangements. Copyright © 2017 The Authors. Published by Elsevier Ltd..

Jacobi, Arnd; Kupke, Carina; Behzad, Melika; Hertl, Michael

2013-09-01

Patients with psoriasis experience a higher risk of cardiovascular and metabolic comorbidities and have a high burden of treatment. There is still a gap between treatment options and quality of care. The purpose of this study was to determine the demographic data, comorbidities, and the limitations of quality of life in patients with plaque-type psoriasis. This epidemiological evaluation was designed as a single-center, cross-sectional, prospective study in Marburg, Germany. To investigate the association between mild to severe psoriasis and comorbidities, data were obtained from 133 patients. The average Psoriasis Area and Severity Index was 13.4, and the average Dermatology Life Quality Index was 6.3. Among the patients with severe psoriasis, 95% had been prescribed systemic treatments. Comorbidities were evaluated, with depression 30.8%, arterial hypertension 39.1%, and hypercholesterolemia 20.3% in all patients. Our findings underscore the importance of cardiovascular and metabolic risk screening for all patients with psoriasis. There is still a need for systemic treatments and the definition of treatment goals for psoriasis as a systemic inflammatory disease. Such goals should integrate parameters that include comorbidities and an improvement in health-related quality of life. © 2013 The International Society of Dermatology.

To assess the prevalence and risk factors of emergency peripartum hysterectomy. Nordic collaborative study. 605 362 deliveries across the five Nordic countries. We collected data prospectively from patients undergoing emergency peripartum hysterectomy within 7 days of delivery from medical birth registers and hospital discharge registers. Control populations consisted of all other women delivering on the same units during the same time period. Emergency peripartum hysterectomy rate. The total number of emergency peripartum hysterectomies reached 211, yielding an incidence rate of 3.5/10 000 (95% confidence interval 3.0-4.0) births. Finland had the highest prevalence (5.1) and Norway the lowest (2.9). Primary indications included an abnormally invasive placenta (n = 91, 43.1%), atonic bleeding (n = 69, 32.7%), uterine rupture (n = 31, 14.7%), other bleeding disorders (n = 12, 5.7%), and other indications (n = 8, 3.8%). The delivery mode was cesarean section in nearly 80% of cases. Previous cesarean section was reported in 45% of women. Both preterm and post-term birth increased the risk for emergency peripartum hysterectomy. The number of stillbirths was substantially high (70/1000), but the case fatality rate stood at 0.47% (one death, maternal mortality rate 0.17/100 000 deliveries). A combination of prospective data collected from clinicians and information gathered from register-based databases can yield valuable data, improving the registration accuracy for rare, near-miss cases. However, proper and uniform clinical guidelines for the use of well-defined international diagnostic codes are still needed. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

Data sources used were MEDLINE (through January 19, 2011) and Web of Science (through March 14, 2011). Two investigators independently extracted results from eligible studies. Heterogeneity between the studies was assessed using the I(2) statistic, and the possibility of publication bias was assessed using the funnel plot and Egger's test for small-study effects. Twelve studies were identified (7 case-control, 4 prospective, and 1 cross-sectional). For a total of 22,518 participants (2,313 CHD cases), the minimally adjusted relative risk of CHD for long working hours was 1.80 (95% confidence interval (CI): 1.42, 2.29), and in the maximally (multivariate-) adjusted analysis the relative risk was 1.59 (95% CI: 1.23, 2.07). The 4 prospective studies produced a relative risk of 1.39 (95% CI: 1.12, 1.72), while the corresponding relative risk in the 7 case-control studies was 2.43 (95% CI: 1.81, 3.26). Little evidence of publication bias but relatively large heterogeneity was observed. Studies varied in size, design, measurement of exposure and outcome, and adjustments. In conclusion, results from prospective observational studies suggest an approximately 40% excess risk of CHD in employees working long hours.

Sleep duration and cardiometabolic risk: a review of the epidemiologic evidence.

PubMed

Knutson, Kristen L

2010-10-01

Laboratory studies have found that short-term sleep restriction is associated with impairments in glucose metabolism, appetite regulation and blood pressure regulation. This chapter reviews the epidemiologic evidence for an association between habitual sleep duration and quality and risk of cardiometabolic diseases including obesity, diabetes and hypertension. Multiple studies observed a cross-sectional association between short sleep duration (generally <6 h per night) and increased body mass index or obesity, prevalent diabetes and prevalent hypertension. Many studies also reported an association between self-reported long sleep duration (generally >8 h per night) and cardiometabolic disease. There have been a few prospective studies and several, but not all, have found an association between short sleep and incident diabetes, hypertension and markers of cardiovascular disease. Future prospective epidemiologic studies need to include objective measures of sleep, and intervention studies are needed in order to establish a causal link between impaired or insufficient sleep and cardiometabolic disease risk.

Retaining subjects from disadvantaged populations in long-term studies is necessary to obtain high-quality data. This article presents cumulative retention rates from a 5-year prospective cohort study, the Pediatric Pulmonary and Cardiovascular Complications of Vertically Transmitted HIV Infection study. It also presents results of a cross-sectional qualitative survey about factors that induced caregivers to stay in the study. Although the repeated study visits were long and uncomfortable, cumulative retention among the 298 HIV-infected children was 80%. Incentives considered important by the caregivers included phone contact with nurse coordinators, nurse coordinators accompanying the caregiver and child during visits, phone reminders for appointments, help with scheduling, meals and transportation, access to health care, and relationships with staff. Thus, the high follow-up rate was in part due to nurses’ efforts to reduce the study’s burden on the families, provide tangible and intangible incentives, and establish personal relationships with families.

Aims: To present the available empirical evidence for the assumed position of the concept of work related fatigue as: (1) short term effect of the working day; and (2) an intermediate variable between work demands and the development of subjective health complaints and sickness absence. Methods: Results from six single occupation studies, conducted between 1996 and 2002, are presented. Work demands (working hours, decision latitude, break control/autonomy, and mental, emotional, and physical demands) were assessed through validated scales. Work related fatigue was represented and assessed by means of the need for recovery after working time scale in all studies. Subjective health complaints and duration of sickness absence were quantified with the same instruments in most studies as well. Both cross sectional studies (four) as well as prospective studies (two; up to two years follow up) were performed. Cross sectional data of 3820 workers, in total, were available. Prospective data were accessible for 1200 workers in industry and health care. Models were tested with stepwise multiple regression analyses. Results: Strong associations between work demands and need for necovery were found in different occupations. The variance explained in need for recovery by work demands, age, and (baseline) need for recovery ranged between 14% and 48% in both types of studies. The amount of explained variance by work demands, age, and (baseline) need for recovery in subjective health complaints ranged between 24% and 58% in the different occupations. The prospective data showed the prognostic value of need for recovery in relation to subjective health complaints (in terms of psychosomatic complaints, emotional exhaustion, or sleep problems) and duration of future sickness absence. Conclusions: The hypothesised role for work related fatigue as a link in the causal string of events, that is assumed to exist between repeated adverse work demands and the development of work related stress reactions, (psychological) overload and, eventually, health problems, was confirmed.

The association between parental myopia and a child's risk of developing the condition is not well understood. Therefore, the present study conducted a meta-analysis of the results of observational studies in order to investigate the association between myopia in parents and their child's risk of developing the condition. The current study systematically examined the databases MEDLINE, Embase and Ovid for relevant studies. Two reviewers independently evaluated the data and extracted the odds ratios (ORs) and 95% confidence intervals (CIs) from the suitable studies. Heterogeneity, publication bias and subgroup analyses were performed. The present meta-analysis included 31,677 participants from 16 studies with 8,393 cases of myopia (six prospective cohort, eight cross-sectional and two case-control studies). The OR of giving birth to a child with myopia, according to the prospective cohort, cross-sectional and case-control studies, was 1.53 (95% CI, 1.21–1.85), 1.96 (95% CI, 1.53–2.39), and 2.13 (95% CI, 1.79–2.46), respectively, when one parent had myopia, and 2.10 (95% CI, 1.42–2.77), 2.96 (95% CI, 2.21–3.71), and 2.13 (95% CI, 1.79–2.46), respectively, when two parents had myopia. The current study identified a significant positive association between parental myopia and a child's risk of developing myopia. Children of two parents with myopia had a higher risk of developing myopia compared to those with one myopic parent. PMID:26136998

To critically appraise recent research into associations between periodontal disease and systemic diseases and conditions specifically respiratory disease, chronic kidney disease, rheumatoid arthritis, cognitive impairment, obesity, metabolic syndrome and cancer. A MEDLINE literature search of papers published between 2002 and April 2012 was conducted. Studies that included periodontitis as an exposure were identified. Cross-sectional epidemiological investigations on large samples, prospective studies and systematic reviews formed the basis of the narrative review. A threshold set for the identification of periodontitis was used to identify those studies that contributed to the conclusions of the review. Many of the investigations were cross-sectional secondary analyses of existing data sets in particular the NHANES studies. There were a small number of systematic reviews and prospective studies. There was substantial variability in the definitions of exposure to periodontitis. A small number of studies met the threshold set for periodontitis and supported associations; however, in some of the chronic diseases there were no such studies. There was strong evidence from randomized controlled trials that interventions, which improve oral hygiene have positive effects on the prevention of nosocomial pneumonias. There was substantial heterogeneity in the definitions used to identify periodontitis and very few studies met a stringent threshold for periodontitis. Published evidence supports modest associations between periodontitis and some, although not all, of the diseases and conditions reviewed. There is a need to reach a consensus on what constitutes periodontitis for future studies of putative associations with systemic diseases.

The suggested associations between sex hormone concentrations and inflammatory biomarkers in men originate from cross-sectional studies and small-scale clinical trials. But prior studies have not investigated longitudinal associations. Overall, 1344 men aged 20-79 years from the population-based cohort Study of Health in Pomerania were followed up for 5.0 (median) years. We used multivariable regression models to analyze cross-sectional and longitudinal associations of serum sex hormone concentrations (total testosterone [TT], sex hormone-binding globulin [SHBG], calculated free testosterone [free T], and dehydroepiandrosterone sulfate [DHEAS]) with biomarkers of inflammation (fibrinogen, high-sensitive C-reactive protein [hsCRP], and white blood cell count [WBC]) and oxidative stress (γ-glutamyl transferase [GGT]) using ordinary least square regression and generalized estimating equation models, respectively. Cross-sectional models revealed borderline associations of sex hormone concentrations with hsCRP, WBC, and GGT levels that were not retained after multivariable adjustment. Longitudinal multivariable analyses revealed an inverse association of baseline TT, free T, and DHEAS concentrations with change in fibrinogen levels (per SD decrement in TT, 0.25 [95% confidence interval, 0.04-0.45]; in free T, 0.30 [0.09-0.51]; and in DHEAS, 0.23 [0.11-0.36]). Furthermore, baseline DHEAS concentrations were inversely associated with change in WBC levels (per SD decrement, 0.53 [0.24-0.82]). Baseline TT, SHBG, free T, and DHEAS concentrations were also inversely associated with change in GGT after multivariable adjustment. The present study is the first to demonstrate prospective inverse associations between sex hormone concentrations and markers of inflammation and oxidative stress in men. Additional studies are warranted to elucidate potential mechanisms underlying the revealed associations.

Metabolic syndrome (MetS), a multicomponent condition, is a cardiovascular disease predictor. Although exposure to agricultural pesticides has been suggested as a potential contributor to the rising rates of obesity, type 2 diabetes, and other features of metabolic disorders, no studies have focused on the association between consumption of organic food (produced without synthetic pesticides) and MetS. We aimed to investigate the cross-sectional association between organic food consumption and MetS in French adults to determine whether it would be worth conducting further studies, particularly large prospective and randomised trials. A total of 8174 participants from the NutriNet-Santé study who attended a clinical visit and completed an organic food frequency questionnaire were included in this cross-sectional analysis. We evaluated the association between the proportion of organic food in the diet (overall and by food group) and MetS using Poisson regression models while adjusting for potential confounders. Higher organic food consumption was negatively associated with the prevalence of MetS: adjusted prevalence ratio was 0.69 (95% CI 0.61, 0.78) when comparing the third tertile of proportion of organic food in the diet with the first one (p value <0.0001). Higher consumption of organic plant-based foods was also related to a lower probability of having MetS. In addition, when stratifying by lifestyle factors (nutritional quality of the diet, smoking status, and physical activity), a significant negative association was detected in each subgroup (p values <0.05), except among smokers. Our results showed that a higher organic food consumption was associated with a lower probability of having MetS. Additional prospective studies and randomised trials are required to ascertain the relationship between organic food consumption and metabolic disorders.

Association of serum 25-hydroxyvitamin D₃ and D₂ with academic performance in childhood: findings from a prospective birth cohort.

Higher total serum 25-hydroxyvitamin D (25(OH)D) concentrations have been associated with better cognitive function mainly in cross-sectional studies in adults. It is unknown if the associations of different forms of 25(OH)D (25(OH)D(3) and 25(OH)D(2)) are similar. Prospective cohort study (n=3171) with serum 25(OH)D(3) and 25(OH)D(2) concentrations measured at mean age of 9.8 years and academic performance at age 13-14 years (total scores in English, mathematics and science) and 15-16 years (performance in General Certificates of Education examinations). Serum 25(OH)D(3) concentrations were not associated with any educational outcomes. Higher 25(OH)D(2) concentrations were associated with worse performance in English at age 13-14 years (adjusted SD change per doubling in 25(OH)D(2) (95% CI) -0.05 (-0.08 to -0.01)) and with worse academic performance at age 15-16 years (adjusted OR for obtaining ≥5 A*-C grades (95% CI) 0.91 (0.82 to 1.00)). The null findings with 25(OH)D(3) are in line with two previous cross-sectional studies in children. It is possible that the positive association of 25(OH)D with cognitive function seen in adults does not emerge until later in life or that the results from previous cross-sectional adult studies are due to reverse causality. The unexpected inverse association of 25(OH)D(2) with academic performance requires replication in further studies. Taken together, our findings do not support suggestions that children should have controlled exposure to sunlight, or vitamin D supplements, in order to increase academic performance.

Electrical resistivity surveys in Prospect Gulch, San Juan County, Colorado

McDougal, Robert R.

2006-01-01

Prospect Gulch is a major source of naturally occurring and mining related metals to Cement Creek, a tributary of the upper Animas River in southwestern Colorado. Efforts to improve water quality in the watershed have focused on Prospect Gulch because many of its abandoned mines and are located on federal lands. Information on sources and pathways of metals, and related ground-water flow, will be useful to help prioritize and develop remediation strategies. It has been shown that the occurrence of sulfate, aluminum, iron, zinc and other metals associated with historical mining and the natural weathering of pyritic rock is substantial. In this study, direct current resistivity surveys were conducted to determine the subsurface resistivity distribution and to identify faults and fractures that may act as ground-water conduits or barriers to flow. Five lines of resistivity data were collected in the vicinity of Prospect Gulch, and cross-section profiles were constructed from the field data using a two-dimensional inversion algorithm. The conductive anomalies in the profiles are most likely caused by wet or saturated rocks and sediments, clay rich deposits, or high TDS ground water. Resistive anomalies are likely bedrock, dry surficial and sub-surface deposits, or deposits of ferricrete.

Background Whether hip range of motion (ROM) is a risk factor for groin pain in athletes is not known. Objectives To systematically review the relationship between hip ROM and groin pain in athletes in cross-sectional/case–control and prospective studies. Study design Systematic review, prospectively registered (PROSPERO) according to PRISMA guidelines. Methods Pubmed, Embase, CINAHL and SPORTDiscus were systematically searched up to December 2015. Two authors performed study selection, data extraction/analysis, quality assessment (Critical Appraisal Skills Programme) and strength of evidence synthesis. Results We identified seven prospective and four case–control studies. The total quality score ranged from 29% to 92%. Heterogeneity in groin pain classification, injury definitions and physical assessment precluded data pooling. There was strong evidence that total rotation of both hips below 85° measured at the pre-season screening was a risk factor for groin pain development. Strong evidence suggested that internal rotation, abduction and extension were not associated with the risk or presence of groin pain. Conclusion Total hip ROM is the factor most consistently related to groin pain in athletes. Screening for hip ROM is unlikely to correctly identify an athlete at risk of developing groin pain because of the small ROM differences found and poor ROM measurement properties. PMID:28432076

Exhaled carbon monoxide (eCO) and fractional exhaled nitric oxide (FeNO) could reflect underlying inflammatory and oxidative stresses, which play important roles in pathogenetic pathways of metabolic syndrome (MetS). However, epidemiologic evidence was limited. We conducted a study in Wuhan-Zhuhai (WHZH) cohort of 3649 community participants to investigate the association between eCO, FeNO and MetS in both cross-sectional and prospective ways. The results showed that higher eCO and FeNO were associated cross-sectionally with a higher prevalence of MetS. The multivariable-adjusted odds ratios for MetS at baseline were 1.22 (95% confidence interval [CI]: 1.11 to 1.35) associated with per log eCO and 1.14 (95% CI: 1.00 to 1.30) associated with per log FeNO. During a follow-up of 3 years, 358/2181 new developed MetS cases were identified. Compared with lowest quartile of eCO and FeNO, the multivariable-adjusted risk ratios (95% CI) for MetS were 1.48 (1.06 to 2.06) related to the highest quartile of eCO. These findings remained consistent across sex but not smoking status, eCO was only associated with MetS in non-smokers when stratified by smoking status. In conclusion, our study demonstrated that eCO and FeNO were independently and positively associated with the prevalence of MetS cross-sectionally, while only eCO was positively related with the incidence of MetS prospectively.

An observational prospective cohort study of incidence and characteristics of failed spinal anaesthesia for caesarean section.

PubMed

Sng, B L; Lim, Y; Sia, A T H

2009-07-01

A prospective cohort study was performed in 800 parturients undergoing elective caesarean section under spinal anaesthesia from May 2005 to April 2006 in a large maternity hospital in Singapore, in order to determine the incidence of and risk factors for total and partial failure of spinal anaesthesia. A routine single-shot spinal technique using intrathecal 0.5% heavy bupivacaine 2.0 mL (10 mg) and morphine 100 microg was administered with a 27-gauge Whitacre spinal needle via a 20-gauge introducer. Demographic, surgical and anaesthetic data were collected to determine risk factors for failure of spinal anaesthesia. Incidence of total failure requiring conversion to general anaesthesia was 0.5% (4 cases) in which three cases had inadequate block (loss of sensation to cold less than T6) and one case had no sensory block. Thirty-three parturients (4.1%) required intravenous fentanyl and seven (0.9%) required Entonox for intraoperative analgesic supplementation. Postpartum sterilization (P<0.001) was an independent risk factor for partial failure requiring intravenous fentanyl and Entonox. Spinal anaesthesia using bupivacaine 10 mg with morphine 100 microg produces reliable anaesthesia for elective caesarean section. Postpartum sterilization involves exteriorisation of the uterus with additional surgical manipulation and hence may necessitate analgesic supplementation. The initial use of a combined spinal-epidural technique or the addition of intrathecal fentanyl or clonidine or an increased dose of local anaesthetic may be considered to decrease the incidence of intraoperative pain.

Cultural psychiatry: research strategies and future directions.

PubMed

Kirmayer, Laurence J; Ban, Lauren

2013-01-01

This chapter reviews some key aspects of current research in cultural psychiatry and explores future prospects. The first section discusses the multiple meanings of culture in the contemporary world and their relevance for understanding mental health and illness. The next section considers methodological strategies for unpacking the concept of culture and studying the impact of cultural variables, processes and contexts. Multiple methods are needed to address the many different components or dimensions of cultural identity and experience that constitute local worlds, ways of life or systems of knowledge. Quantitative and observational methods of clinical epidemiology and experimental science as well as qualitative ethnographic methods are needed to capture crucial aspects of culture as systems of meaning and practice. Emerging issues in cultural psychiatric research include: cultural variations in illness experience and expression; the situated nature of cognition and emotion; cultural configurations of self and personhood; concepts of mental disorder and mental health literacy; and the prospect of ecosocial models of health and culturally based interventions. The conclusion considers the implications of the emerging perspectives from cultural neuroscience for psychiatric theory and practice. Copyright © 2013 S. Karger AG, Basel.

This study examined cross-sectional and prospective associations between cognitive appraisals and posttraumatic stress disorder (PTSD) symptoms following stroke. While in hospital, stroke patients (n=81) completed questionnaires assessing cognitive appraisals (i.e., negative cognitions about the self, negative cognitions about the world, and self-blame) and PTSD symptoms. PTSD symptoms were assessed again 3 months later when all patients had been discharged from hospital (n=70). Significant correlations were found between the time 1 measures of negative cognitions about the self and the world, but not self-blame, and the severity of PTSD symptoms measured at time 1 and at time 2. Regression analyses revealed that cognitive appraisals explained a significant amount of variance in the severity of PTSD symptoms at time 1, with negative cognitions about the self-emerging as a significant predictor. In contrast, time 1 cognitive appraisals were unable to explain additional variance in time 2 PTSD severity over and above that explained by time 1 PTSD severity. The findings therefore provide only weak support for Ehlers and Clark's cognitive model of PTSD.

To describe the arch morphology and the prevalence and severity of malocclusions in 8-year-old children with DS, and to evaluate their need for treatment using the Norwegian Need for Orthodontic Treatment Index (NOTI), and comparing the findings with a control group. This population-based cross-sectional study was part of a national prospective study evaluating upper airway function, hearing, dental, and craniofacial characteristics in a cohort of children with DS in Norway. The cohort consisted of 32 children with DS and represented 57% of all children born with DS in Norway in 2002. Dental arch morphology and malocclusion were assessed on dental casts. Data were collected prospectively at the TAKO-centre, National Resource Center for Oral Health in Rare Medical Conditions. All the children with DS (100%) had objectively assessed needs for orthodontic treatment, compared with 30% of the normative comparison group. Among the children with DS, 68% were objectively categorized as being in "great need" (Category B) for treatment and the 75% were categorized as having "obvious need" (Category C). In comparison, only 20% of children without DS were in Category B, and 44% were in Category C. This study indicates significantly higher prevalence and severity of malocclusions in 8-year-old children with DS compared with control group. © 2016 Special Care Dentistry Association and Wiley Periodicals, Inc.

Roane, Brandy M.; Taylor, Daniel J.

2008-01-01

Study Objective: To evaluate the association between adolescent insomnia and mental health during adolescence and young adulthood. Design: Cross-sectional and prospective study. Settings: School and in home. Participants: Nationally based population sample of 4494 adolescents, 12 to 18 years old at baseline (mean = 15.83 years), with 3582 young adults, 18 to 25 years old (mean = 21.25 years) at 6- to 7-year follow-up. Measures: Self-report measures of mental health. Results: Insomnia symptoms were reported by 9.4% of the adolescents. Cross-sectionally, adolescent insomnia symptoms were associated with use of alcohol, cannabis, and drugs other than cannabis; depression; suicide ideation; and suicide attempts (all P values < 0.01) after controlling for sex. Prospectively, insomnia symptoms during adolescence were a significant risk factor for depression diagnosis (odds ratio = 2.3) in young adulthood after controlling for sex and baseline depression. Conclusion: This study is the first to longitudinally evaluate insomnia symptoms during adolescence as a risk factor for mental health problems in young adulthood. The findings indicate that insomnia is a prevalent problem for adolescents and argue for future treatment-outcome studies to evaluate the efficacy and effectiveness of various insomnia interventions in this age group.

InternationaL cross-sectIonAl and longItudinal assessment on aSthma cONtrol in European adult patients - the LIAISON study protocol

PubMed Central

2013-01-01

Background According to international guidelines, the goal of asthma management is to achieve and maintain control of the disease, which can be assessed using composite measures. Prospective studies are required to determine how these measures are associated with asthma outcomes and/or future risk. The ‘InternationaL cross-sectIonAl and longItudinal assessment on aSthma cONtrol (LIAISON)’ observational study has been designed to evaluate asthma control and its determinants, including components of asthma management. Methods/design The LIAISON study will be conducted in 12 European countries and comprises a cross-sectional phase and a 12-month prospective phase. Both phases will aim at assessing asthma control (six-item Asthma Control Questionnaire, ACQ), asthma-related quality of life (Mini Asthma Quality of Life Questionnaire, Mini-AQLQ), risk of non-adherence to treatment (four-item Morisky Medication Adherence Scale, MMAS-4), potential reasons for poor control, treatment strategies and associated healthcare costs. The cross-sectional phase will recruit > 8,000 adult patients diagnosed with asthma for at least 6 months and receiving the same asthma treatment in the 4 weeks before enrolment. The prospective phase will include all patients with uncontrolled/poorly controlled asthma at the initial visit to assess the proportion reaching control during follow-up and to examine predictors of future risk. Visits will take place after 3, 6 and 12 months. Discussion The LIAISON study will provide important information on the prevalence of asthma control and on the quality of life in a broad spectrum of real-life patient populations from different European countries and will also contribute to evaluate differences in management strategies and their impact on healthcare costs over 12 months of observation.

2018-03-01

This study systematically reviewed literature regarding the impact of ambient air pollution on physical activity among children and adults. Keyword and reference search was conducted in PubMed and Web of Science to systematically identify articles meeting all of the following criteria - study designs: interventions or experiments, retrospective or prospective cohort studies, cross-sectional studies, and case-control studies; subjects: adults; exposures: specific air pollutants and overall air quality; outcomes: physical activity and sedentary behaviour; article types: peer-reviewed publications; and language: articles written in English. Meta-analysis was performed to estimate the pooled effect size of ambient PM 2.5 air pollution on physical inactivity. Seven studies met the inclusion criteria. Among them, six were conducted in the United States, and one was conducted in the United Kingdom. Six adopted a cross-sectional study design, and one used a prospective cohort design. Six had a sample size larger than 10,000. Specific air pollutants assessed included PM 2.5 , PM 10 , O 3 , and NO x , whereas two studies focused on overall air quality. All studies found air pollution level to be negatively associated with physical activity and positively associated with leisure-time physical inactivity. Study participants, and particularly those with respiratory disease, self-reported a reduction in outdoor activities to mitigate the detrimental impact of air pollution. Meta-analysis revealed a one unit (μg/m 3 ) increase in ambient PM 2.5 concentration to be associated with an increase in the odds of physical inactivity by 1.1% (odds ratio = 1.011; 95% confidence interval = 1.001, 1.021; p-value < .001) among US adults. Existing literature in general suggested that air pollution discouraged physical activity. Current literature predominantly adopted a cross-sectional design and focused on the United States. Future studies are warranted to implement a longitudinal study design and evaluate the impact of air pollution on physical activity in heavily polluted developing countries.

State Medicaid reimbursement methods and rates are reported for the period 1978-86 for skilled nursing and intermediate care facilities. A cross-sectional time series regression analysis of Medicaid reimbursement rates on methods showed that States using prospective class reimbursement had significantly lower rates for the period 1982-86. States using prospective facility-specific reimbursement methods had lower rates than retrospective methods in 1983-84. PMID:10312516

Studies have indicated that children delivered by cesarean section are at an increased risk of developing wheezing and asthma. This could be the result of an altered immune system development due to delayed gut colonization or of increased neonatal respiratory morbidity. The authors examined the associations between delivery by cesarean section and the development of wheezing, asthma, and recurrent lower respiratory tract infections in children up to 36 months of age among 37,171 children in the Norwegian Mother and Child Cohort Study. Generalized linear models were used in the multivariable analysis. Children delivered by cesarean section had an increased likelihood of current asthma at 36 months of age (relative risk = 1.17, 95% confidence interval: 1.03, 1.32), and the association was stronger among children of nonatopic mothers (relative risk = 1.33, 95% confidence interval: 1.12, 1.58). No increased risk of wheezing or recurrent lower respiratory tract infections was seen among children delivered by cesarean section. Findings were similar among children delivered by acute and elective cesarean section. In conclusion, children delivered by cesarean section may have an increased risk of current asthma at 36 months, but residual confounding cannot be excluded. In future prospective studies, investigators should reexamine this association in different age groups. PMID:22038100

Association between background exposure to organochlorine pesticides and the risk of cognitive impairment: A prospective study that accounts for weight change.

Background exposure to organochlorine (OC) pesticides was recently linked to cognitive impairment and dementia in cross-sectional and case-control studies. This prospective study was performed to evaluate if OC pesticides at baseline are associated with the future risk of cognitive impairment in elderly, with particular focus on weight change. Plasma concentrations of 3 OC pesticides (p,p'-DDE, trans-nonachlor, and hexachlorobenzene) were measured among 989 men and women aged 70years in the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS). Cognitive impairment was validated by reviewing medical records. During the ten year follow-up, cognitive impairment was developed in 75 subjects. When weight change from age 70 to 75 was considered in analyses, elderly with incident cases before age 75 were excluded to keep the prospective perspective, leaving 795 study subjects and 44 incident cases. The summary measure of 3 OC pesticides predicted the development of cognitive impairment after adjusting for covariates, including weight change. Compared to subjects with OC pesticides <25th percentile, adjusted hazard ratios (HRs) in those with 25th-<75th and ≥75th percentiles were 3.5 (95% confidence interval: 1.5-8.5) and 3.2 (1.1-7.6), respectively (Ptrend=0.04). Among 506 subjects who maintained or gained body weight, adjusted HRs were 6.9 and 11.6 (1.4-92.6) among the elderly in the 25th-<75th and ≥75th percentiles compared to <25th percentile (Ptrend<0.01). This prospective study demonstrates that background exposure to OC pesticides are linked to the risk of developing cognitive impairment in elderly. The role of the chronic exposure to low dose OC pesticides in the development of dementia should be further evaluated in other populations. Copyright © 2016 Elsevier Ltd. All rights reserved.

Potential sources of bias in the use of Escherichia coli to measure waterborne diarrhoea risk in low-income settings.

Escherichia coli is the standard water quality indicator for diarrhoea risk. Yet, the association between E. coli and diarrhoea is inconsistent across studies without a systematic assessment of methodological differences behind this variation. Most studies measure water quality cross-sectionally with diarrhoea, risking exposure misclassification and reverse causation. Studies use different recall windows for self-reported diarrhoea; longer periods increase potential outcome misclassification through misrecall. Control of confounding is inconsistent across studies. Additionally, diarrhoea measured in unblinded intervention trials can present courtesy bias. We utilised measurements from a randomised trial of water interventions in Bangladesh to assess how these factors affect the E. coli-diarrhoea association. We compared cross-sectional versus prospective measurements of water quality and diarrhoea, 2-versus 7-day symptom recall periods, estimates with and without controlling for confounding and using measurements from control versus intervention arms of the trial. In the control arm, 2-day diarrhoea prevalence, measured prospectively 1 month after water quality, significantly increased with log 10 E. coli (PR = 1.50, 1.02-2.20). This association weakened when we used 7-day recall (PR = 1.18, 0.88-1.57), cross-sectional measurements of E. coli and diarrhoea (PR = 1.11, 0.79-1.56) or did not control for confounding (PR = 1.20, 0.88-1.62). Including data from intervention arms led to less interpretable associations, potentially due to courtesy bias, effect modification and/or reverse causation. By systematically addressing potential sources of bias, our analysis demonstrates a clear relationship between E. coli in drinking water and diarrhoea, suggesting that the continued use of E. coli as an indicator of waterborne diarrhoea risk is justified. © 2016 John Wiley & Sons Ltd.

No relationship between circulating levels of sex steroids and mammographic breast density: the Prospect-EPIC cohort

Background High breast density is associated with increased breast cancer risk. Epidemiologic studies have shown an increase in breast cancer risk in postmenopausal women with high levels of sex steroids. Hence, sex steroids may increase postmenopausal breast cancer risk via an increase of breast density. The objective of the present study was to study the relation between circulating oestrogens and androgens as well as sex hormone binding globulin (SHBG) in relation to breast density. Methods We conducted a cross-sectional study among 775 postmenopausal women, using baseline data of a random sample of the Prospect-EPIC study. Prospect-EPIC is one of two Dutch cohorts participating in the European Prospective Investigation into Cancer and Nutrition, and women were recruited via a breast cancer screening programme. At enrolment a nonfasting blood sample was taken and a mammogram was made. Oestrone, oestradiol, dehydroepiandrosterone sulfate, androstenedione, testosterone and SHBG levels were measured, using double-antibody radioimmunoassays. Concentrations of free oestradiol and free testosterone were calculated from the measured oestradiol, testosterone and SHBG levels Mammographic dense and nondense areas were measured using a semiquantitative computerized method and the percentage breast density was calculated. Mean breast measures for quintiles of hormone or SHBG levels were estimated using linear regression analyses. Results Both oestrogens and testosterone were inversely related with percent breast density, but these relationships disappeared after adjustment for BMI. None of the sex steroids or SHBG was associated with the absolute measure of breast density, the dense area. Conclusion The results of our study do not support the hypothesis that sex steroids increase postmenopausal breast cancer risk via an increase in breast density. PMID:17692133

Most cross-sectional studies have found a significant positive relationship between periodontal disease and prehypertension/hypertension. However, these studies had limitations and there are few prospective cohort studies in young adults. The purpose of this prospective cohort study was to investigate whether periodontal disease was related to prehypertension/hypertension in Japanese university students. Students (n = 2,588), who underwent health examinations before entering university and before graduation, were included in the analysis. The association between periodontal disease such as the percentage of bleeding on probing (BOP) and community periodontal index (CPI) scores, and change in blood pressure status was determined. At the reexamination, the numbers of participants with prehypertension (systolic blood pressure 120-139mm Hg or diastolic blood pressure 80-89mm Hg) and hypertension (≥140/90mm Hg) were 882 (34.1%) and 109 (4.2%), respectively. In a logistic regression model, the risk of hypertension was significantly associated with male (odds ratio (OR): 6.31; 95% confidence interval (CI): 2.63-15.13; P < 0.001), no habitual physical activity at baseline (OR: 2.90; 95% CI: 1.56-5.38; P < 0.01) and periodontal disease defined as the presence of both probing pocket depth (PPD) ≥ 4mm and BOP ≥ 30% at baseline (OR: 2.74; 95% CI: 1.19-6.29; P = 0.02) in participants with prehypertension at baseline. On the other hand, the risk of prehypertension was not associated with presence of periodontal disease (OR: 0.93; 95% CI: 0.51-1.70; P = 0.82). In the short-term prospective cohort study, a significant association between presence of periodontal disease and hypertension was observed in Japanese university students. © American Journal of Hypertension, Ltd 2015.

Performance characteristics of optical coherence tomography in assessment of Barrett's esophagus and esophageal cancer: systematic review.

PubMed

Kohli, D R; Schubert, M L; Zfass, A M; Shah, T U

2017-11-01

Optical coherence tomography (OCT) can generate high-resolution images of the esophagus that allows cross-sectional visualization of esophageal wall layers. We conducted a systematic review to assess the utility of OCT for diagnosing of esophageal intestinal metaplasia (IM; Barrett's esophagus BE)), dysplasia, cancer and staging of early esophageal cancer. English language human observational studies and clinical trials published in PubMed and Embase were included if they assessed any of the following: (i) in-vivo features and accuracy of OCT at diagnosing esophageal IM, sub-squamous intestinal metaplasia (SSIM), dysplasia, or cancer, and (ii) accuracy of OCT in staging esophageal cancer. Twenty-one of the 2,068 retrieved citations met inclusion criteria. In the two prospective studies that assessed accuracy of OCT at identifying IM, sensitivity was 81%-97%, and specificity was 57%-92%. In the two prospective studies that assessed accuracy of OCT at identifying dysplasia and early cancer, sensitivity was 68%-83%, and specificity was 75%-82%. Observational studies described significant variability in the ability of OCT to accurately identify SSIM. Two prospective studies that compared the accuracy of OCT at staging early squamous cell carcinoma to histologic resection specimens reported accuracy of >90%. Risk of bias and applicability concerns was rated as low among the prospective studies using the QUADAS-2 questionnaire. OCT may identify intestinal metaplasia and dysplasia, but its accuracy may not meet recommended thresholds to replace 4-quadrant biopsies in clinical practice. OCT may be more accurate than EUS at staging early esophageal cancer, but randomized trials and cost-effective analyses are lacking. © The Authors 2017.

Development of borderline personality disorder in adolescence and young adulthood: introduction to the special section.

PubMed

Stepp, Stephanie D

2012-01-01

Recognizable symptoms and features of borderline personality disorder (BPD) appear during adolescence. However, there has been resistance to diagnose or research this disorder prior to adulthood because of clinical lore that BPD is a long-standing illness and that personality traits are not stable until adulthood. This has resulted in little information regarding the development of and risk factors for BPD in youth. The goal of this special section is to examine the development of BPD in adolescence and young adulthood using a broad collection of approaches, including a theoretical review paper, two prospective studies, and a multi-method cross-sectional study. This body of work provides new insights into vulnerabilities that may transact with early attachment relationships and experiences to predict the emergence of BPD in adolescence and young adulthood. These papers also point to future research that is needed to better understand the etiology, development, and course of BPD.

The effects of epidural analgesia on the course and outcome of labour.

PubMed

Finster, M; Santos, A C

1998-09-01

The potential effects of epidural analgesia on the progress and outcome of labour have been the subject of lasting controversy. Retrospective reviews indicate that epidurals are associated with longer labours and/or an increase in the incidence of instrumental or operative delivery. Similar results were obtained in non-randomized prospective studies. None of them established a causal relationship, because without randomization the selection bias cannot be ruled out. Other factors, such as premature rupture of membranes and maternal socioeconomic status, may affect the outcome of labour. It was also reported that introduction of the on-demand epidural service did not increase the primary caesarean section rate. The few prospective randomized studies are contradictory and not very reliable owing to small patient populations and high cross-over rates. There is, however, unanimity among the authors regarding the superiority of pain relief provided by epidural blocks over systemically administered opioids.

Emotional inertia prospectively predicts the onset of depressive disorder in adolescence.

2012-04-01

Emotional inertia refers to the degree to which a person's current emotional state is predicted by their prior emotional state, reflecting how much it carries over from one moment to the next. Recently, in a cross-sectional study, we showed that high inertia is an important characteristic of the emotion dynamics observed in psychological maladjustment such as depression. In the present study, we examined whether emotional inertia prospectively predicts the onset of first-episode depression during adolescence. Emotional inertia was assessed in a sample of early adolescents (N = 165) based on second-to-second behavioral coding of videotaped naturalistic interactions with a parent. Greater inertia of both negative and positive emotional behaviors predicted the emergence of clinical depression 2.5 years later. The implications of these findings for the understanding of the etiology and early detection of depression are discussed. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

This prospective clinical study examined standard wrist magnetic resonance imaging (MRI) examinations and the incremental value of computed tomography (CT) in the diagnosis of Kienböck's disease (KD) with regard to reliability and precision in the different diagnostic steps during diagnostic work-up. Sixty-four consecutive patients referred between January 2009 and January 2014 with positive initial suspicion of KD according to external standard wrist MRI were prospectively included (step one). Institutional review board approval was obtained. Clinical examination by two handsurgeons were followed by wrist radiographs (step two), ultrathin-section CT, and 3T contrast-enhanced MRI (step three). Final diagnosis was established in a consensus conference involving all examiners and all examinations results available from step three. In 12/64 patients, initial suspicion was discarded at step two and in 34/64 patients, the initial suspicion of KD was finally discarded at step three. The final external MRI positive predictive value was 47%. The most common differential diagnoses at step three were intraosseous cysts (n=15), lunate pseudarthrosis (n=13), and ulnar impaction syndrome (n=5). A correlation between radiograph-based diagnoses (step two) with final diagnosis (step three) showed that initial suspicion of stage I KD had the lowest sensitivity for correct diagnosis (2/11). Technical factors associated with a false positive external MRI KD diagnosis were not found. Standard wrist MRI should be complemented with thin-section CT, and interdisciplinary interpretation of images and clinical data, to increase diagnostic accuracy in patients with suspected KD.

A cross-sectional and prospective longitudinal study on the anthropometric parameters and growth pattern of girls with adolescent idiopathic scoliosis (AIS). To investigate the growth pattern of girls with AIS with different severities, using cross-sectional and prospective longitudinal data set in comparison with age-matched healthy controls. AIS occurs in children during their pubertal growth spurt. Although there is no clear consensus on the difference in body height between girls with AIS and healthy controls, it is generally thought that the development and curve progression in girls with AIS is closely associated with their growth rate. There is no concrete prospective longitudinal study to document clearly the growth pattern and growth rate of subjects with AIS . A total of 611 girls with AIS and 296 healthy age-matched controls were included in the study and among them, 194 girls with AIS and 116 healthy controls were followed up until skeletal maturity. The girls with AIS were grouped into moderate (AIS20) and severe curve (AIS40) groups on the basis of maximum curve magnitude at skeletal maturity. Clinical data and detailed anthropometric parameters were recorded. In the cross-sectional analysis, the groups of subjects were compared within different age groups (from the age of 12-16 yr). In the longitudinal study, linear mixed modeling with respect to age or years since menarche was employed to formulate the growth trajectory of different anthropometric parameters. In the cross-sectional analysis, the girls with AIS were generally taller, with longer arm span and lower body mass index than the healthy controls. The girls with AIS40 were found to be significantly shorter in height (P = 0.006) and arm span (P = 0.025) at the age of 12 years but caught up and overtook the control group at the age of 14 to 16 years. In the longitudinal study, the average growth rate of arm span in girls with AIS40 was significantly higher than that in girls with AIS20 (> 30%) (P = 0.004) and controls (> 70%) (P = 0.0004). The age of menarche of girls with AIS40 was significantly delayed by 5.9 months and 3.8 months when compared with the control group and girls with AIS20, respectively (P < 0.05). The growth patterns of girls with AIS with confirmed curve severities were significantly different from healthy age-matched controls. Girls with severe AIS had delayed menarche with faster skeletal growth rate during the age of 12 to 16 years. Monitoring the rate of change of arm span of girls with AIS could be an important additional clinical parameter in helping predict curve severity in girls with AIS.

To evaluate the effects of amnioinfusion in oligohydramniosis. During a 20-month period, patients at term with oligohydramniosis (amniotic fluid index less than 5 cm) at Huddinge University and Norrköping Hospitals were recruited for a prospective randomized study to evaluate amnioinfusion. Informed consent was obtained from 112 patients who met the entry criteria. Sixty subjects were randomized to amnioinfusion and 52 to the control group. Outcome parameters included fetal heart rate abnormalities, mode of delivery, Apgar score, pH in umbilical artery blood and need for neonatal intensive care. The cesarean section rate was significantly reduced in the amnio-infusion group (29% versus 13%, p=0.043). No difference in time from randomization to delivery was detected between the two groups. The frequency of ominous fetal heart rate tracings with a cervical dilatation of 0-3 cm was the same in the two groups. The frequency of such heart rate patterns after amnioinfusion was significantly lower than in the control group. Neonatal outcome, pH in the umbilical artery blood and need for neonatal intensive care did not differ between the two groups. The present study confirms the findings of other authors that amnioinfusion effectively reduces the number of cesarean sections in cases of oligohydramniosis.

Existing epidemiological studies of the association between oxidative stress and erectile dysfunction (ED) are sparse and inconclusive, which is likely due to cross-sectional design and small sample size. Therefore, we investigated the association between biomarkers of oxidative stress and ED in prospective setting among a relatively large sample size of men. We conducted the prospective study among 917 men ages between 47 and 80 years at the time of blood draw, which is a part of nested prospective case-control study of prostate cancer in the Health Professionals Follow-up Study. Plasma fluorescent oxidation products (FlOPs), a global biomarker for oxidative stress, were measured at three excitation/emission wavelengths (360/420 nm named as FlOP_360; 320/420 nm named as FlOP_320 and 400/475 nm named as FlOP_400). Approximately 35% of men developed ED during follow-up. We did not find an independent association between FlOP_360, FlOP_320, FlOP_400 and risk of ED in the multivariable adjusted model (Tertile 3 vs. tertile 1: odds ratio [OR] = 0.90, 95% confidence interval [CI] = 0.61-1.34, P(trend) = 0.54 for FlOP_360; OR = 0.73, 95% CI = 0.49-1.07, P(trend) = 0.27 for FlOP_320; and OR = 0.98, 95% CI = 0.66-1.45, P(trend) = 0.72 for FlOP_400). Further analysis of the association between FlOPs and ED in the fasting samples or controls only (free of prostate cancer incidence) did not change the results appreciably. Plasma FlOPs were not associated with the risk of ED, suggesting oxidative stress may not be an independent risk factor for ED.

Cardiovascular disease (CVD) is the leading cause of death worldwide. There is a consistent inverse relationship between fruit intake with CVD events and mortality in cross-sectional and prospective observational studies, but the relationship of fruit intake with measurements of atherosclerosis in humans is less clear. Nutritional effects on abdominal aortic calcification (AAC), a marker for subclinical intimal and medial atherosclerotic vascular disease, have not been studied previously. The aim of this study was to examine the cross-sectional relationship of total and individual fruit (apple, pear, orange and other citrus, and banana) intake with AAC, scored between 0 and 24. The current study assessed baseline data for a cohort of 1052 women over 70 years of age who completed both a food frequency questionnaire assessing fruit intake, and underwent AAC measurement using dual energy X-ray absorptiometry. AAC scores were significantly negatively correlated with total fruit and apple intakes (p < 0.05), but not with pear, orange or banana intakes (p > 0.25). In multivariable-adjusted logistic regression, each standard deviation (SD; 50 g/day) increase in apple intake was associated with a 24% lower odds of having severe AAC (AAC score >5) (odd ratio OR): 0.76 (0.62, 0.93), p = 0.009). Total and other individual fruit intake were not associated with increased odds of having severe AAC. Apple but not total or other fruit intake is independently negatively associated with AAC in older women. PMID:26978394

To examine the relationship between dry eye symptoms and adiposity in a population study. A prospective cross-sectional single-visit preliminary study was designed to sample ocular symptoms and indices of adiposity in the general adult population. Patients recruited from the UNSW optometry clinic, the university campus and surrounding community, and overseas were invited to complete a survey composed of the short form Dry Eye Questionnaire (SFDEQ) (Dry Eye Questionnaire-5 or Contact Lens Dry Eye Questionnaire-8) and the Ocular Comfort Index (OCI) via hardcopy or online. Participants self-measured their weight, height, waist circumference (WC), and body fat % (optional). Associations between measures of adiposity (Body mass index [BMI], WC, and body fat %) and ocular symptoms scores (SFDEQ and OCI) were determined using Spearman correlation coefficients. Group differences were compared using independent t test. Three hundred and five participants including 52 contact lens wearers completed the study and 78 of them measured body fat %. There was a moderate correlation between body fat % and dry eye symptoms (SFDEQ r=0.34, P=0.003; OCI r=0.32, P=0.004). The interaction between body fat % and gender, wear of contact lenses, and older age were shown to be significant predictors of less ocular comfort in multivariate analysis (F(3,74)=12.13, P<0.001). An association between adiposity measured by body fat % and symptoms of dry eye was demonstrated in the general adult population. Confirmation of these findings in a large study is required.

Background Eating in the Absence of Hunger (EAH), or consuming highly palatable foods when satiated, is one behavioral pathway that may lead to childhood obesity. EAH is an objective, laboratory-based measure. A more comprehensive understanding of potential determinants of EAH could inform childhood obesity programs outside of a laboratory setting. Objective Systematic review of EAH experiments to identify individual, familial, and societal-level correlates of EAH among children 12 years of age or younger. Design 1,487 studies were retrieved from five electronic databases (Medline [PubMed], Web of Science, Cochrane Library, CINAHL, PsycINFO). Eligible studies were those that measured EAH as initially operationalized in a laboratory setting enrolling children ≤12 years or reporting age-specific results for children ≤12 years. Only articles written in English were included. Results 12 cross-sectional, six prospective, and one behavioral-intervention studies were included in the review. EAH was observable among boys and girls; absolute levels of EAH increased with age; and maternal feeding styles were associated with EAH among girls. The most consistent evidence supported increased levels of EAH among overweight and obese versus normal weight children, both cross-sectionally and prospectively. Two studies supported a genetic component to EAH. Conclusions Studies enrolling independent samples support a positive association between weight status and EAH among children; studies addressing causality are needed. Other various individual, genetic, and familiar characteristics were associated with EAH, yet studies among more heterogeneous sample populations are needed to confirm findings. Studies addressing societal-level factors related to EAH were absent. PMID:25450900

The Public Health (PH) course at the medical college of Cairo University is based on traditional lectures. Large enrollment limits students' discussions and interactions with instructors. Evaluate students' learning outcomes as measured by improved knowledge acquisition and opinions of redesigning the Reproductive Health (RH) section of the PH course into e-learning and assessing e-course utilization. This prospective interventional study started with development of an e-learning course covering the RH section, with visual and interactive emphasis, to satisfy students' diverse learning styles. Two student groups participated in this study. The first group received traditional lecturing, while the second volunteered to enroll in the e-learning course, taking online course quizzes. Both groups answered knowledge and course evaluation questionnaires and were invited to group discussions. Additionally, the first group answered another questionnaire about reasons for non-participation. Students participating in the e-learning course showed significantly better results, than those receiving traditional tutoring. Students who originally shunned the e-course expressed eagerness to access the course before the end of the academic year. Overall, students using the redesigned e-course reported better learning experiences. An online course with interactivities and interaction, can overcome many educational drawbacks of large enrolment classes, enhance student's learning and complement pit-falls of large enrollment traditional tutoring.

Adherent placenta is a life-threatening condition in pregnancy, and is often complicated by placenta previa. The aim of this prospective study was to determine prenatal imaging findings that predict the presence of adherent placenta in pregnancies with placenta previa. The study included 58 consecutive pregnant women with placenta previa who underwent both ultrasonography and magnetic resonance imaging prenatally. Ultrasonographic findings of anterior placental location, grade 2 or higher placental lacunae (PL≥G2), loss of retroplacental hypoechoic clear zone (LCZ) and the presence of turbulent blood flow in the arteries were evaluated, in addition to MRI findings. Forty-three women underwent cesarean section alone; 15 women with adherent placenta underwent cesarean section followed by hysterectomy with pathological examination. To determine imaging findings that predict adherent placenta, univariate and multivariate logistic regression analyses were performed. Univariate logistic regression analyses demonstrated that anterior placental location, PL≥G2, LCZ, and MRI were associated with the presence of adherent placenta. Multivariate analyses revealed that LCZ (p<0.01, odds ratio 15.6, 95%CI 2.1-114.6) was a single significant predictor of adherent placenta in women with placenta previa. This prospective study demonstrated for the first time that US findings, especially LCZ, might be useful for identifying patients at high risk for adherent placenta among pregnant women with placenta previa.

Purpose Conduct problems and peer effects are among the strongest risk factors for adolescent substance use and problem use. However, it is unclear to what extent the effects of conduct problems and peer behavior interact, and whether adolescents' capacity to refuse the offer of substances may moderate such links. This study was conducted to examine relationships between conduct problems, close friends' substance use, and refusal assertiveness with adolescents' alcohol use problems, tobacco, and marijuana use. Methods We studied a population-based sample of 1,237 individuals from the Cardiff Study of All Wales and North West of England Twins aged 11–18 years. Adolescent and mother-reported information was obtained. Statistical analyses included cross-sectional and prospective logistic regression models and family-based permutations. Results Conduct problems and close friends' substance use were associated with increased adolescents' substance use, whereas refusal assertiveness was associated with lower use of cigarettes, alcohol, and marijuana. Peer substance use moderated the relationship between conduct problems and alcohol use problems, such that conduct problems were only related to increased risk for alcohol use problems in the presence of substance-using friends. This effect was found in both cross-sectional and prospective analyses and confirmed using the permutation approach. Conclusions Reduced opportunities for interaction with alcohol-using peers may lower the risk of alcohol use problems in adolescents with conduct problems. PMID:20547290

To collect medical data on women's boxing. Cross-sectional and longitudinal study. Medical examinations requested by Italian laws. A retrospective study was conducted on all female boxing competitions in Italy from April 2001 to December 2007. Sixty-one amateur female boxers were evaluated longitudinally. (1) Retrospective study: All pre-/postmatch medical reports were analysed. (2) Prospective study: Breast, gynaecologic, brain, eyes, ear, nose and throat examinations were carried out. (1) Retrospective study: Any injury assessed before/after the match. (2) Prospective study: Health problems which could be related to boxing activity. (1) Retrospective study: Data from 5600 examinations were collected. Precompetition, a medical problem was recorded in three athletes (one conjunctiva hyperemia, one zygomatic bruise, one eyelid haematoma). Post competition, 51/2800 medical checks showed mild common injuries, such as soft tissue facial lesions, epistaxis and hand-wrist problems. Only one concussion was recorded with hospitalisation (for a thorough evaluation). Another athlete was hospitalised for a nasal fracture. (2) Prospective study: Two fibroadenomas, three ovarian cysts and one intramural uterine myoma were diagnosed. In four boxers, non-specific electroencephalographic abnormalities were detected, however, with a normal brain MRI in three (the fourth is still waiting for the radiologic procedure). Nasal septum deviation was common (42.6%) and a transmissive hypoacusia was observed in two athletes. No major eye injuries were reported. Female boxing seems to be a safe sport with a very low incidence of events requiring hospitalisation. No specific diseases in female boxers could be observed, in particular regarding the breast and reproductive system.

2014-01-01

Ti-based alloys are finding ever-increasing applications in biomaterials due to their excellent mechanical, physical and biological performance. Nowdays, low modulus β-type Ti-based alloys are still being developed. Meanwhile, porous Ti-based alloys are being developed as an alternative orthopedic implant material, as they can provide good biological fixation through bone tissue ingrowth into the porous network. This paper focuses on recent developments of biomedical Ti-based alloys. It can be divided into four main sections. The first section focuses on the fundamental requirements titanium biomaterial should fulfill and its market and application prospects. This section is followed by discussing basic phases, alloying elements and mechanical properties of low modulus β-type Ti-based alloys. Thermal treatment, grain size, texture and properties in Ti-based alloys and their limitations are dicussed in the third section. Finally, the fourth section reviews the influence of microstructural configurations on mechanical properties of porous Ti-based alloys and all known methods for fabricating porous Ti-based alloys. This section also reviews prospects and challenges of porous Ti-based alloys, emphasizing their current status, future opportunities and obstacles for expanded applications. Overall, efforts have been made to reveal the latest scenario of bulk and porous Ti-based materials for biomedical applications. PMID:28788539

We investigated whether three self-system beliefs -- fear of abandonment, coping efficacy, and self-esteem -- mediated the relations between stressors and caregiver-child relationship quality and parentally bereaved youths’ general grief and intrusive grief thoughts. Cross-sectional (n=340 youth) and longitudinal (n=100 youth) models were tested. In the cross-sectional model, fear of abandonment mediated the effects of stressors and relationship quality on both measures of grief and coping efficacy mediated the path from relationship quality to general grief. Fear of abandonment showed a marginal prospective mediational relation between stressors and intrusive grief thoughts. After excluding the mediators, relationship quality showed a direct prospective relation to intrusive grief thoughts. PMID:18924290

2013-01-01

The United States Supreme Court's recent decision relating to violent video games revealed divisions within the scientific community about the potential for negative effects of such games as well as the need for more, higher quality research. Scholars also have debated the potential for violent games to have positive effects such as on visuospatial cognition or math ability. The current study sought to extend previous literature by using well-validated clinical outcome measures for relevant constructs, which have generally been lacking in past research. Cross-section data on aggression, visuospatial cognition, and math achievement were available for a sample of 333 (51.7 % female) mostly Hispanic youth (mean age = 12.76). Prospective 1-year data on aggression and school GPA were available for 143 (46.2 % female) of those youth. Results from both sets of analysis revealed that exposure to violent game had neither short-term nor long-term predictive influences on either positive or negative outcomes. A developmental analysis of the cross-sectional data revealed that results did not differ across age categories of older children, preadolescents or adolescents. Analysis of effect sizes largely ruled out Type II error as a possible explanation for null results. Suggestions for new directions in the field of video game research are proffered.

This study examined the morbidity experience from 1981 to 1988 of a prospective cohort of 3422 refinery and petrochemical plant employees from the Shell Deer Park manufacturing complex. The morbidity data for this study, which include all illness and absence records in excess of five days, were extracted from the morbidity section of the Shell health surveillance system. Standardised morbidity ratios (SMRs) of disease prevalence in this cohort were calculated using an internal comparison group of all manufacturing employees of the Shell Oil Company. Among production employees, the overall morbidity was statistically significantly higher (SMR = 109) than that of the comparison group. Illness due to hypertension (SMR = 144), haemorrhoids (SMR = 149), diseases of the nervous system (SMR = 120), respiratory system (SMR = 108), and digestive system (SMR = 117) were also raised for this group. The increased risk due to these medical conditions does not appear to be associated with occupational factors. Lymphatic and haematopoietic tissue neoplasms were raised (SMR = 124), but were based on only four cases. PMID:1637713

To determine the frequency of surgical site infection in patients undergoing laparoscopic cholecystectomy with instruments sterilized by peracetic acid. We conducted a retrospective, cohort, descriptive, cross-sectional study. Peracetic acid has been used for sterilization following the protocol recommended by the manufacturer. We observed the criteria and indicators of process and structure for preventing surgical site infection pre and intraoperatively. For epidemiological surveillance, outpatient visits were scheduled for the 15th and between the 30th and 45th days after discharge. Among the 247 patients, there were two cases of surgical site infection (0.8%). One patient was readmitted to systemic antibiotic therapy and percutaneous puncture; in the other the infection was superficial and followed at the clinic. Ethical issues prevent the conduction of a prospective study because of peracetic acid have been banned for the sterilization of instruments that penetrate organs and cavities. Nevertheless, these results encourage prospective case-control studies comparing its use (historical control) with ethylene oxide sterilization.

Explicit and implicit cognition: a preliminary test of a dual-process theory of cognitive vulnerability to depression.

Haeffel, Gerald J; Abramson, Lyn Y; Brazy, Paige C; Shah, James Y; Teachman, Bethany A; Nosek, Brian A

2007-06-01

Two studies were conducted to test a dual-process theory of cognitive vulnerability to depression. According to this theory, implicit and explicit cognitive processes have differential effects on depressive reactions to stressful life events. Implicit processes are hypothesized to be critical in determining an individual's immediate affective reaction to stress whereas explicit cognitions are thought to be more involved in long-term depressive reactions. Consistent with hypotheses, the results of study 1 (cross-sectional; N=237) showed that implicit, but not explicit, cognitions predicted immediate affective reactions to a lab stressor. Study 2 (longitudinal; N=251) also supported the dual-process model of cognitive vulnerability to depression. Results showed that both the implicit and explicit measures interacted with life stress to predict prospective changes in depressive symptoms, respectively. However, when both implicit and explicit predictors were entered into a regression equation simultaneously, only the explicit measure interacted with stress to remain a unique predictor of depressive symptoms over the five-week prospective interval.

The relationship between workplace bullying and mental health problems are well documented in previous cross-sectional studies, but knowledge on how this relationship develops over time is still scarce. The aim of this study was to explore the prospective relationship between exposure to bullying behaviors at baseline, and increased symptoms of mental health problems (anxiety, depression, fatigue) one year later. Furthermore, the reverse relationship was investigated. This is a prospective longitudinal study, where members of the Norwegian Nurses Organization answered identical questions regarding workplace bullying and mental health problems, at baseline (2008-2009) and follow-up (2010). Altogether, 1582 nurses completed both questionnaires. Hierarchical regression analyses indicated that exposure to bullying behaviors at baseline predicted subsequent increased symptoms of anxiety and fatigue, after adjusting for baseline symptoms of anxiety and fatigue respectively, age, gender, night work and job demands. Moreover, symptoms of anxiety, depression and fatigue at baseline predicted increased exposure to bullying behaviors one year later, after adjusting for exposure to bullying behaviors at baseline, age, gender, night work and job demands. In this study we find support for a reciprocal relationship between exposure to bullying behaviors and symptoms of anxiety and fatigue, respectively. Thus, the results may indicate a vicious circle where workplace bullying and mental health problems mutually affect each other negatively. Copyright © 2013 Elsevier Ltd. All rights reserved.

Social capital and the course of depression: six-month prospective cohort study.

2011-03-01

Previous research has found an inverse cross-sectional relationship between an individual's access to social capital (defined as resources embedded within social networks) and depression, but this relationship has not been rigorously tested in prospective research. This is the first longitudinal study to evaluate the effect of social capital on the course of depression and subjective quality of life in a clinical population. This was a six-month prospective cohort study of people with depression in primary care achieving a follow-up rate of 91.3% (n=158). Depression was measured with the HAD-D and social capital using the Resource Generator-UK. Potential confounding variables including socio-demographics, socio-economic status, depression history, social support, life events and attachment style were also measured. Social capital had no independent effect on the course of depression, though an interaction of access to social capital and attachment style was significantly related to change in quality of life alongside multiple covariates. The study used a small sample; a short follow-up period; no measure of ecological social capital; no genetic components; and only two time points. Emotional support is important for the alleviation of depression. Additionally, people with depression may require a secure attachment style to derive the full benefit of their social capital.

To examine children's screen media exposure and requests for advertised toys and food/drinks. Prospective cohort study. Twelve elementary schools in northern California. Eight hundred twenty-seven third grade children participated at baseline; 386 students in 6 schools were followed up for 20 months. None. Child self-reported requests for advertised toys and foods/drinks. At baseline, children's screen media time was significantly associated with concurrent requests for advertised toys (Spearman r = 0.15 [TV viewing] and r = 0.20 [total screen time]; both P<.001) and foods/drinks (Spearman r = 0.16 [TV viewing] and r = 0.18 [total screen time]; both P<.001). In prospective analysis, children's screen media time at baseline was significantly associated with their mean number of toy requests 7 to 20 months later (Spearman r = 0.21 [TV viewing] and r = 0.24 [total screen time]; both P<.001) and foods/drinks requests (Spearman r = 0.14 [TV viewing] and r = 0.16 [total screen time]; both P<.01). After adjusting for baseline requests and sociodemographic variables, the relationship between screen media exposure and future requests for advertised foods/drinks remained significant for total TV viewing and total screen media exposure. The relationship with future requests for toys remained significant for total screen media exposure. Screen media exposure is a prospective risk factor for children's requests for advertised products. Future experimental studies on children's health- and consumer-related outcomes are warranted.

Typically, studies of cognitive advantages in bilinguals have been conducted previously by using executive and inhibitory tasks (e.g. Simon task) and applying cross-sectional designs. This study longitudinally investigated bilingual advantages on episodic memory recall, verbal letter and categorical fluency during the trajectory of life. Monolingual and bilingual participants (n = 178) between 35–70 years at baseline were drawn from the Betula Prospective Cohort Study of aging, memory, and health. Results showed that bilinguals outperformed monolinguals at the first testing session and across time both in episodic memory recall and in letter fluency. No interaction with age was found indicating that the rate of change across ages was similar for bilinguals and monolinguals. As predicted and in line with studies applying cross-sectional designs, no advantages associated with bilingualism were found in the categorical fluency task. The results are discussed in the light of successful aging. PMID:24023803

Neoadjuvant chemoradiation (nCRT) followed by esophagectomy is a treatment with curative intent for resectable esophageal cancer. The aim of this study was to measure activities of daily living (ADL) and quality of life (QoL), and to examine correlates of changes in ADL and QoL. A prospective study was performed with three time points (baseline, 1 week after the end of nCRT, 3-months post-surgery) together with a cross-sectional post-treatment study. ADL was measured with the Amsterdam Linear Disability Score (ALDS), and QoL with the EORTC QLQ-C30 and the OES-18. Regression analysis was performed to identify factors associated with changes in ADL and QoL. Seventy-six patients were included in the prospective study, 79 in the cross-sectional study. After nCRT, ALDS decreased from 90 to 88 (P < 0.01) and remained stable after surgery. Global QoL decreased from 75 to 61 (P < 0.01); no significant changes were observed after surgery. Only timing of the measurement of ALDS was negatively associated with non-maximum ALDS (n = 155, based on both studies) and QoL (n = 76) (P < 0.01). Patients who undergo nCRT plus surgery should be prepared to experience a short-term decline in ADL and QoL. The findings of this study can support patients and healthcare workers to guide expectations. J. Surg. Oncol. 2016;114:684-690. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

The aim of this study was to investigate how sleep, screen time, active school travel and sport and/or exercise participation associates with moderate-to-vigorous physical activity (MVPA) in nationally representative samples of Norwegian 9- and 15-y-olds, and whether these four behaviors at age nine predict change in MVPA from age nine to 15 years. We pooled cross-sectional accelerometer and questionnaire data from 9- (n = 2366) and 15-y-olds (n = 1554) that participated in the first (2005/06) and second (2011/12) wave of the Physical Activity among Norwegian Children Study to investigate cross-sectional associations. To investigate prospective associations, we used data from a sub-sample that participated in both waves (at age nine and 15 years, n = 517). Cross-sectional analyses indicated a modest, inverse association between screen time and MVPA among 9- (- 2.2 min/d (95% CI: -3.1, - 1.3)) and 15-y-olds (- 1.7 min/d (95% CI: -2.7, - 0.8)). Compared to their peers with 0-5 min/d of active travel to school, 9- and 15-y-olds with ≥16 min/d accumulated 7.2 (95% CI: 4.0, 10.4) and 9.0 (95% CI: 3.8, 14.1) more min/d of MVPA, respectively. Nine-y-old boys and 15-y-olds reporting ≥8 h/week of sports and/or exercise participation accumulated 14.7 (95% CI: 8.2, 21.3) and 17.9 (95% CI: 14.0, 21.8) more min/d of MVPA, respectively, than those reporting ≤2 h/week. We found no cross-sectional association between sleep duration and MVPA in either age group. None of the four behaviors predicted change in MVPA from age nine to 15 years (p ≥ 0.102). Active travel to school and sport/exercise participation may be important targets for future interventions aimed at increasing MVPA in children and adolescents. However, future studies are needed to determine causality.

Since the Great East Japan Earthquake in 2011, many of the affected have been forced to live in temporary housing or at a relative's house. Special attention needs to be paid to the negative health impacts resulting from such changes in living conditions. This study examined the association between future housing prospects and the risk of psychological distress 1 year after the earthquake. In 2012, a questionnaire was completed by a cross-sectional study of people aged 20 years or older living in Shichigahama Town, Miyagi, northeastern Japan, an area that had been severely inundated by the tsunami. Future housing prospects post-earthquake were classified into four categories: already settled in permanent housing, moving to new housing, under consideration, or unable to make any plans. Psychological distress was evaluated using the Kessler 6 scale, defined as ≥5 points out of 24. We performed multiple logistic regression analyses adjusted for potential confounding factors. Of the 3614 individuals studied, subjects whose future housing was under consideration (odds ratio [OR] = 2.1, 95% confidence interval [CI] = 1.6-2.7, P < 0.01) and those who were unable to make any future housing plans (OR = 1.9, 95%CI = 1.4-2.5, P < 0.01) exhibited a significantly higher risk of psychological distress compared with subjects who had already settled in permanent housing. In this study, subjects whose future housing prospects were under consideration and those who were unable to make any future housing plans were at a higher risk of psychological distress 1 year after the earthquake disaster. © 2015 The Authors.

Seeing light at the end of the tunnel: Positive prospective mental imagery and optimism in depression.

PubMed

Ji, Julie L; Holmes, Emily A; Blackwell, Simon E

2017-01-01

Optimism is associated with positive outcomes across many health domains, from cardiovascular disease to depression. However, we know little about cognitive processes underlying optimism in psychopathology. The present study tested whether the ability to vividly imagine positive events in one's future was associated with dispositional optimism in a sample of depressed adults. Cross-sectional and longitudinal analyses were conducted, using baseline (all participants, N=150) and follow-up data (participants in the control condition only, N=63) from a clinical trial (Blackwell et al., 2015). Vividness of positive prospective imagery, assessed on a laboratory-administered task at baseline, was significantly associated with both current optimism levels at baseline and future (seven months later) optimism levels, including when controlling for potential confounds. Even when depressed, those individuals able to envision a brighter future were more optimistic, and regained optimism more quickly over time, than those less able to do so at baseline. Strategies to increase the vividness of positive prospective imagery may aid development of mental health interventions to boost optimism. Copyright © 2016 The Authors.

The aim of this study was to investigate the prevalence of post-cesarean isthmocele and to measure agreement between transvaginal ultrasonography and saline contrast sonohysterography in assessment of isthmocele. Prospective observational cohort study was carried out at Tampere University Hospital, Finland. Non-pregnant women delivered by cesarean section (n=371) were examined with transvaginal ultrasonography (TVUS) and sonohysterography (SHG) six months after cesarean section. The main outcome measure was the prevalence of isthmocele using TVUS and SHG. Secondary outcome measures were characteristics of isthmocele. Three hundred and seventy-one women were included. The prevalence of isthmocele was 22.4% based on TVUS and 45.6% based on SHG. Sensitivity and specificity for TVUS was 49.1 and 100% when compared to SHG. Therefore, half of the defects (50.9%) diagnosed with SHG remained undiagnosed with TVUS. Bland-Altman analysis showed an underestimation of 1.1 mm (range 0.00 to 7.90) for TVUS compared to SHG, with 95% limits of agreement from -1.9 to 4.1 mm. This methodological study provides confirmatory data that TVUS and SHG are not in good agreement in the isthmocele diagnostics and the use of only TVUS may lead to an underestimation of the prevalence of isthmocele. Thus, SHG should be considered as a method of choice in diagnostics of isthmocele. This article is protected by copyright. All rights reserved. This article is protected by copyright.

Marijuana or Cannabis is extensively used as a recreational substance globally. Case reports have reported cardiac arrhythmias immediately following recreational marijuana use. However, the burden of arrhythmias in hospitalized marijuana users have not been evaluated through prospective or cross-sectional studies. Therefore, we planned to measure temporal trends of the frequency of arrhythmias in hospitalized marijuana users using National Inpatient Sample (NIS) database in the United States.

2016-11-01

We summarize the prospects for Higgs boson physics at future proton-proton colliders with centre of mass (c.m.) energies up to 100 TeV. We first provide the production cross sections for the Higgs boson of the Standard Model from 13 TeV to 100 TeV, in the main production mechanisms and in subleading but important ones such as double Higgs production, triple production and associated production with two gauge bosons or with a single top quark. We then discuss the production of Higgs particles in beyond the Standard Model scenarios, starting with the one in the continuum of a pair of scalar, fermionic and vector dark matter particles in Higgs-portal models in various channels with virtual Higgs exchange. The cross sections for the production of the heavier CP-even and CP-odd neutral Higgs states and the charged Higgs states in two-Higgs doublet models, with a specific study of the case of the Minimal Supersymmetric Standard Model, are then given. The sensitivity of a 100 TeV proton machine to probe the new Higgs states is discussed and compared to that of the LHC with a c.m. energy of 14 TeV and at high luminosity.

Survival bias and drug interaction can attenuate cross-sectional case-control comparisons of genes with health outcomes. An example of the kinesin-like protein 6 (KIF6) Trp719Arg polymorphism and coronary heart disease.

PubMed

Williams, Paul; Pendyala, Lakshmana; Superko, Robert

Case-control studies typically exclude fatal endpoints from the case set, which we hypothesize will substantially underestimate risk if survival is genotype-dependent. The loss of fatal cases is particularly nontrivial for studies of coronary heart disease (CHD) because of significantly reduced survival (34% one-year fatality following a coronary attack). A case in point is the KIF6 Trp719Arg polymorphism (rs20455). Whereas six prospective studies have shown that carriers of the KIF6 Trp719Arg risk allele have 20% to 50% greater CHD risk than non-carriers, several cross-sectional case-control studies failed to show that carrier status is related to CHD. Computer simulations were therefore employed to assess the impact of the loss of fatal events on gene associations in cross-sectional case-control studies, using KIF6 Trp719Arg as an example. Ten replicates of 1,000,000 observations each were generated reflecting Canadian demographics. Cardiovascular disease (CVD) risks were assigned by the Framingham equation and events distributed among KIF6 Trp719Arg genotypes according to published prospective studies. Logistic regression analysis was used to estimate odds ratios between KIF6 genotypes. Results were examined for 33%, 41.5%, and 50% fatality rates for incident CVD.In the absence of any difference in percent fatalities between genotypes, the odds ratios (carriers vs. noncarriers) were unaffected by survival bias, otherwise the odds ratios were increasingly attenuated as the disparity between fatality rates increased between genotypes. Additional simulations demonstrated that statin usage, shown in four clinical trials to substantially reduce the excess CHD risk in the KIF6 719Arg variant, should also attenuate the KIF6 719Arg odds ratio in case-control studies. These computer simulations show that exclusions of prior CHD fatalities attenuate odds ratios of case-control studies in proportion to the difference in the percent fatalities between genotypes. Disproportionate CHD survival for KIF6 Trip719Arg carriers is suggested by their 50% greater risk for recurrent myocardial infarction. This, and the attenuation of KIF6 719Arg carrier risk with statin use, may explain the genotype's weak association with CHD in cross-sectional case-control studies. The results may be relevant to the underestimation of risk in cross-sectional case-control studies of other genetic CHD-risk factors affecting survival.

The role of vitamin D in the prevention of late-life depression.

In this article, we review current evidence regarding potential benefits of vitamin D for improving mood and reducing depression risk in older adults. We summarize gaps in knowledge and describe future efforts that may clarify the role of vitamin D in late-life depression prevention. MEDLINE and PsychINFO databases were searched for all articles on vitamin D and mood that had been published up to and including May 2015. Observational studies and randomized trials with 50 or more participants were included. We excluded studies that involved only younger adults and/or exclusively involved persons with current depression. Twenty observational (cross-sectional and prospective) studies and 10 randomized trials (nine were randomized placebo-controlled trials [RCTs]; one was a randomized blinded comparison trial) were reviewed. Inverse associations of vitamin D blood level or vitamin D intake with depression were found in 13 observational studies; three identified prospective relations. Results from all but one of the RCTs showed no statistically significant differences in depression outcomes between vitamin D and placebo groups. Observational studies were mostly cross-sectional and frequently lacked adequate control of confounding. RCTs often featured low treatment doses, suboptimal post-intervention changes in biochemical levels of vitamin D, and/or short trial durations. Vitamin D level-mood associations were observed in most, but not all, observational studies; results indicated that vitamin D deficiency may be a risk factor for late-life depression. However, additional data from well-designed RCTs are required to determine the impact of vitamin D in late-life depression prevention. Copyright © 2016 Elsevier B.V. All rights reserved.

ECG interpretation skills of South African Emergency Medicine residents

Wallis, Lee; Maritz, David

2010-01-01

Background The use and interpretation of electrocardiograms (ECGs) are widely accepted as an essential core skill in Emergency Medicine. It is imperative that emergency physicians are expert in ECG interpretation when they exit their training programme. Aim It is unknown whether South African Emergency Medicine trainees are getting the necessary skills in ECG interpretation during the training programme. Currently there are no clear criteria to assess emergency physicians’ competency in ECG interpretation in South Africa. Methods A prospective cross-sectional study of Emergency Medicine residents and recently qualified emergency physicians was conducted between August 2008 and February 2009 using a focused questionnaire. Results At the time of the study, there were 55 eligible trainees in South Africa. A total of 55 assessments were distributed; 50 were returned (91%) and 49 were fully completed (89%). In this study, we found the overall average score of ECG interpretation was 46.4% [95% confidence interval (CI) 41.5–51.2%]. The junior group had an overall average of 42.2% (95% CI 36.9–47.5%), whereas the senior group managed 52.5% (95% CI 43.4–61.5%). Conclusion In this prospective cross-sectional study of Emergency Medicine residents and recently qualified emergency physicians, we found that there was improvement in the interpretation of ECGs with increased seniority. There exists, however, a low level of accuracy for many of the critical ECG diagnoses. The average score of 46.4% obtained in this study is lower than the scores obtained by other international studies from countries where Emergency Medicine is a well-established speciality.

Zhong, Shi-zhen

2003-03-01

As a cutting-edge research project, digitization of human anatomical information combines conventional medicine with information technology, computer technology, and virtual reality technology. Recent years have seen the establishment of, or the ongoing effort to establish various virtual human models in many countries, on the basis of continuous sections of human body that are digitized by means of computational medicine incorporating information technology to quantitatively simulate human physiological and pathological conditions, and to provide wide prospective applications in the fields of medicine and other disciplines. This article addresses 4 issues concerning the progress in virtual human model researches as the following: (1) Worldwide survey of sectioning and modeling of visible human. American visible human database was completed in 1994, which contains both a male and a female datasets, and has found wide application internationally. South Korea also finished the data collection for a male visible Korean human dataset in 2000. (2) Application of the dataset of Visible Human Project (VHP). This dataset has yielded plentiful fruits in medical education and clinical research, and further plans are proposed and practiced to construct a Physical Human and Physiological Human . (3) Scientific significance and prospect of virtual human studies. Digitized human dataset may eventually contribute to the development of many new high-tech industries. (4) Progress of virtual Chinese human project. The 174th session of Xiangshang Science Conferences held in 2001 marked the initiation of digitized virtual human project in China, and some key techniques have been explored. By now the data-collection process for 4 Chinese virtual human datasets have been successfully completed.

Aim To compare the mother-to-infant bond of mothers who gave birth by elective C-section versus urgent C-section in the first 48-72h of life and 10-12weeks after delivery. This is a cohort prospective study of women giving birth by C-section. 48-72h after delivery, sociodemographic variables were collected, Mother-to-Infant Bonding Scale and newborn's response to separation test were performed. 10-12weeks after delivery Mother-to-Infant Bonding Scale and questions about baby's feeding were completed. A total of 116 dyads were recruited, 58 in each group. No significant differences between the two C-sections in bonding, newborn response to separation or type of feeding were observed at any time points. However, those dyads presenting with an abnormal bond at time 1 had more frequently an abnormal bond at time 2 (50% versus 8.1%, p=0.000). No differences in mother-to-infant bond were found according to type of C-section. Copyright © 2017 Elsevier B.V. All rights reserved.

Anger, provider responses, and pain: prospective analysis of stem cell transplant patients.

Patient anger can be challenging for providers, and may hinder the patient-provider relationship. Research on the relationships among patient anger, relationships with health care providers and medical outcomes, however, has been limited to anecdotal accounts and cross-sectional studies. This study examined relationships among patient anger, perceptions of provider positive support and negative interactions, by prospectively studying a sample of stem cell transplant (SCT) patients. A prospective design was used to study patient anger, perceived positive support from providers and perceived negative interactions with providers among 88 SCT patients. Data were obtained upon patient's hospitalization before SCT and at 1, 2, and 3 month follow up periods. Repeated-measures mixed models assessed relationships among study variables. Patient anger was associated with a gradual decline in perceived positive support and higher levels of concurrent perceived negative interactions with providers. Further, a significant lagged relationship was found such that patient anger was associated with increased perceived negative interactions with providers 1 month later. Exploratory analyses revealed that perceived negative interactions were also associated with higher levels of physical distress. Perceived positive support buffered the relationship between patient anger and physical distress, such that anger was not associated significantly with physical distress when perceived provider support was high. Patient anger may contribute to a deterioration of the patient-provider relationship, and contribute to negative medical outcomes including physical distress. The association between patient anger and physical distress may be reduced by supportive providers. PsycINFO Database Record (c) 2015 APA, all rights reserved.

To evaluate the clinical anatomy and presentations of congenital portosystemic shunts, and determine features that promote recognition on imaging. Institutional review board approval was obtained for this HIPAA-compliant study. The requirement for written informed consent was waived. Radiology reports were retrospectively reviewed from non-cirrhotic patients who underwent imaging studies from January 1999 through February 2009. Clinical sources reviewed included electronic medical records, archived images and histopathological material. Eleven patients with congenital portosystemic shunts were identified (six male and five female; age range 20 days to 84 years). Seven patients had extrahepatic and four patients had intrahepatic shunts. All 11 patients had absent or hypoplastic intrahepatic portal veins, a feature detected by CT and MRI, but not by US. Seven patients presented with shunt complications and four with presentations unrelated to shunt pathophysiology. Three adult patients had four splenic artery aneurysms. Prospective radiological evaluation of five adult patients with cross-sectional imaging had failed prospectively to recognize the presence of congenital portosystemic shunts on one or more imaging examinations. Congenital portosystemic shunts are associated with splenic artery aneurysms, a previously unrecognized association. Portosystemic shunts were undetected during prospective radiologic evaluation in the majority of adult patients, highlighting the need to alert radiologists to this congenital anomaly.

Hope, Nora; Koestner, Richard; Holding, Anne; Harvey, Brenda

2016-12-01

Kasser and Ryan (1993,1996) have contrasted two types of life values: intrinsic aspirations, which include community contribution, building close relationships, and self-growth, and extrinsic aspirations, which include fame, wealth, and physical beauty. Prioritization of extrinsic relative to intrinsic aspirations has been related cross-sectionally to decreased well-being (Kasser, 2002). However, the influence of close others in the etiology of young adults' prioritization of extrinsic aspirations, and the prospective effects of aspirations on well-being, are not well understood. In a multiple-informant prospective study of 341 university students (mean age = 19.4; 64% Caucasian; 74% female), we examined the influence of friends' and family members' perfectionism on participants' aspirations, and the outcomes of prioritization of extrinsic aspirations. Having friends high in other-oriented perfectionism was significantly positively related to prioritization of extrinsic over intrinsic aspirations. Furthermore, living with friends amplified the effect. Last, prioritization of extrinsic aspirations at T1 was related to decreased subjective well-being and self-concordance for goals 3 months later. The study provides preliminary evidence for a relationship between friends' other-oriented perfectionism and students' orientation toward extrinsic aspirations, as well as negative prospective consequences of students' orientation to extrinsic aspirations. © 2015 Wiley Periodicals, Inc.

Recent interest in antihypertensive agents, especially calcium channel blockers, has been sparked by the notion that these medications may be neuroprotective. A modest literature, with mixed results, has examined whether these medications might lower the odds or risk of Parkinson's disease (PD) or dementia. There are no data for essential tremor (ET). To examine the association between antihypertensive use (defined broadly and by individual subclasses) and ET, PD and dementia. For each disorder, we used cross-sectional data (association with prevalent disease) and prospective data (association with incident disease). Prospective population-based study in Spain enrolling 5,278 participants at baseline. Use of antihypertensive medications (aside from beta-blockers) was similar in prevalent ET cases and controls. Baseline use of antihypertensive agents was not associated with reduced risk of incident ET. Antihypertensive medication use was not associated with prevalent or incident PD. Calcium channel blocker use was marginally reduced in prevalent dementia cases (OR(adjusted) = 0.63, p = 0.06) but was not associated with reduced risk of incident dementia (RR(adjusted) = 1.02, p = 0.95). We did not find evidence of a protective effect of antihypertensive medications in these three neurodegenerative disorders. Copyright 2009 S. Karger AG, Basel.

Intestinal infections have been claimed to precipitate or aggravate flares of inflammatory bowel disease (IBD). The reported incidence of such infections among IBD patients varies between 9 and 13%, but only a few prospective studies have been conducted. To evaluate the incidence of intestinal infections by enteropathogens in patients with active IBD, their impact on clinical outcome, and to identify associated risk factors. Consecutive patients admitted because of a relapse or suspected onset of IBD were prospectively included. At admittance, stool samples for culture, examination for intestinal parasites, and cytotoxin assay for Clostridium difficile were collected. Baseline clinical characteristics, potential risk factors for gastrointestinal infections, and clinical outcome were recorded. Ninety-nine episodes were included. Six intestinal infections were diagnosed in 6 patients (5 ulcerative colitis, 1 ileocolonic Crohn's disease), Campylobacter jejuni being the most frequent isolated microbe (n = 5). None of the patients with intestinal infection needed surgery, but two of them required second-line therapies. Gastrointestinal infections among IBD patients do not exceed 10% and occur mostly in patients with extensive involvement of the colon. Infection by enteropathogenic bacteria does not appear to be associated with a poorer clinical outcome of the IBD flare. Copyright 2009 S. Karger AG, Basel.

Body dissatisfaction is common among sexual minority (i.e., gay and bisexual) men; however, few studies have investigated the relationship between body dissatisfaction and psychosexual health variables among this population. The data that do exist are exclusively cross-sectional, casting uncertainty regarding temporal associations. Thus, the aims of the current study were to assess the prospective relationship between body dissatisfaction and psychological and sexual health outcomes. Participants were 131 gay and bisexual men who completed a battery of self-report measures across two time points (baseline and 3-month follow-up), including assessment of body dissatisfaction, depressive symptoms, and sexual health variables (sexual self-efficacy and sexual anxiety). Generalized linear modeling was employed to assess the prospective relationship between body dissatisfaction and outcomes variables, accounting for non-normal distributions. Body dissatisfaction significantly predicted elevated depressive symptoms (B = .21, p = .01), lower sexual self-efficacy (B = -.22, p = .04), and elevated sexual anxiety (B = .05, p = .03). Elevated body dissatisfaction is prospectively associated with negative psychological and sexual health outcomes. Given the high prevalence of body image concerns in sexual minority men, depression and/or HIV/STI prevention programs may benefit from routinely assessing for body dissatisfaction among this population, and addressing those who report concerns.

This prospective study was conducted to assess the rate of resolution of second trimester placenta previa in women with anterior placenta and posterior placenta, and that in women with and without previous cesarean section. In this study, placenta previa was defined as a placenta lying within 20 mm of the internal cervical os or overlapping it. We recruited 183 women diagnosed with previa between 20 +0 weeks and 25 +6 weeks. They were grouped according to their placenta location (anterior or posterior) and history of cesarean section. Comparative analysis was performed on demographic data, resolution rate of previa and pregnancy outcomes between anterior group and posterior group, and on those between cesarean section group and non-cesarean section group. Women with an anterior placenta tended to be advanced in parity (P=0.040) and have increased number of dilatation and curettage (P=0.044). The women in cesarean section group were significantly older (P=0.000) and had more parity (P=0.000), gravidity (P=0.000), and dilatation and curettage (P=0.048) than in non-cesarean section group. Resolution of previa at delivery occurred in 87.43% women in this study. Women with a posterior placenta had a higher rate of resolution (P=0.030), while history of cesarean section made no difference. Gestational age at resolution was earlier in posterior group (P=0.002) and non-cesarean section group (P=0.008) than in anterior group and cesarean section group correspondingly. Placenta location and prior cesarean section did not influence obstetric outcomes and neonatal outcomes. This study indicates that it is more likely to have subsequent resolution of the previa when the placenta is posteriorly located for women who are diagnosed with placenta previa in the second trimester.

The aim of the present study was to determine health-related risk and salutogenic factors and to use these to construct prediction models for future self-rated health (SRH), i.e. find possible characteristics predicting individuals improving or worsening in SRH over time (0-12 months). A prospective study was conducted with measurements (physiological markers and self-ratings) at 0, 6 and 12 months, involving 303 employees (187 men and 116 women, age 23-64) from four information technology and two media companies. There were a multitude of statistically significant cross-sectional correlations (Spearman's Rho) between SRH and other self-ratings as well as physiological markers. Predictors of future SRH were baseline ratings of SRH, self-esteem and social support (logistic regression), and SRH, sleep quality and sense of coherence (linear regression). The results of the present study indicate that baseline SRH and other self-ratings are predictive of future SRH. It is cautiously implied that SRH, self-esteem, social support, sleep quality and sense of coherence might be predictors of future SRH and therefore possibly also of various future health outcomes.

Cross-sectional studies and short term interventions focusing on fitness and bone mineral density (BMD) are common. However, few investigations have studied the effect of fitness on BMD over an extended period of time. The present study was conducted to determine the extent to which cardiorespiratory fitness influences risk of BMD loss at the hip over 6 yr. A prospective cohort design was used with 245 healthy, middle-aged women. Hip BMD was assessed using dual energy x-ray absorptiometry. Calcium and vitamin D were measured using the Block Food Frequency Questionnaire. Menopause status was measured by a questionnaire. Results showed that fit and unfit women experienced similar changes in hip BMD over time. Specifically, unfit women experienced a non-significant 7% increased risk of losing hip BMD compared to their counterparts (RR = 1.07, 95% CI = 0.66, 1.73). Adjusting statistically for differences in age, initial body weight, and hip BMD, weight change, menopause status, calcium and vitamin D intake, and time between assessments had little effect on the relationship. Fitness level did not influence risk of hip BMD loss over time.

Polyglutamine expansion spinocerebellar ataxias are autosomal dominant slowly progressive neurodegenerative diseases with no current treatment. MR imaging is the best-studied surrogate biomarker candidate for polyglutamine expansion spinocerebellar ataxias, though with conflicting results. We aimed to review quantitative central nervous system MR imaging technique findings in patients with polyglutamine expansion spinocerebellar ataxias and correlations with well-established clinical and molecular disease markers. We searched MEDLINE, LILACS, and Cochrane data bases of clinical trials between January 1995 and January 2016, for quantitative MR imaging volumetric approaches, MR spectroscopy, diffusion tensor imaging, or other quantitative techniques, comparing patients with polyglutamine expansion spinocerebellar ataxias (SCAs) with controls. Pertinent details for each study regarding participants, imaging methods, and results were extracted. After reviewing the 706 results, 18 studies were suitable for inclusion: 2 studies in SCA1, 1 in SCA2, 15 in SCA3, 1 in SCA7, 1 in SCA1 and SCA6 presymptomatic carriers, and none in SCA17 and dentatorubropallidoluysian atrophy. Cerebellar hemispheres and vermis, whole brain stem, midbrain, pons, medulla oblongata, cervical spine, striatum, and thalamus presented significant atrophy in SCA3. The caudate, putamen and whole brain stem presented similar sensitivity to change compared with ataxia scales after 2 years of follow-up in a single prospective study in SCA3. MR spectroscopy and DTI showed abnormalities only in cross-sectional studies in SCA3. Results from single studies in other polyglutamine expansion spinocerebellar ataxias should be replicated in different cohorts. Additional cross-sectional and prospective volumetric analysis, MR spectroscopy, and DTI studies are necessary in polyglutamine expansion spinocerebellar ataxias. The properties of preclinical disease biomarkers (presymptomatic) of MR imaging should be targeted in future studies. © 2016 by American Journal of Neuroradiology.

This prospective cohort study aimed at identifying association between uric acid (UA) and peripheral arterial stiffness. A prospective cohort longitudinal study was performed according to an average of 4.8 years' follow-up. The demographic data, anthropometric parameters, peripheral arterial stiffness (carotid-radial pulse-wave velocity, cr-PWV) and biomarker variables including UA were examined at both baseline and follow-up. Pearson's correlations were used to identify the associations between UA and peripheral arterial stiffness. Further logistic regressions were employed to determine the associations between UA and arterial stiffness. At the end of follow-up, 1447 subjects were included in the analyses. At baseline, cr-PWV ( r  = 0.200, p  < 0.001) was closely associated with UA. Furthermore, the follow-up cr-PWV ( r  = 0.145, p  < 0.001) was also strongly correlated to baseline UA in Pearson's correlation analysis. Multiple regressions also indicated the association between follow-up cr-PWV ( β  = 0.493, p  = 0.013) and baseline UA level. Logistic regressions revealed that higher baseline UA level was an independent predictor of arterial stiffness severity assessed by cr-PWV at follow-up cross-section. Peripheral arterial stiffness is closely associated with higher baseline UA level. Furthermore, a higher baseline UA level is an independent risk factor and predictor for peripheral arterial stiffness.

We studied HSA measurements in relation to hip fracture risk in 4,806 individuals (2,740 women). Hip fractures (n = 147) occurred at the same absolute levels of bone instability in both sexes. Cortical instability (propensity of thinner cortices in wide diameters to buckle) explains why hip fracture risk at different BMD levels is the same across sexes. Despite the sexual dimorphism of bone, hip fracture risk is very similar in men and women at the same absolute BMD. We aimed to elucidate the main structural properties of bone that underlie the measured BMD and that ultimately determines the risk of hip fracture in elderly men and women. This study is part of the Rotterdam Study (a large prospective population-based cohort) and included 147 incident hip fracture cases in 4,806 participants with DXA-derived hip structural analysis (mean follow-up, 8.6 yr). Indices compared in relation to fracture included neck width, cortical thickness, section modulus (an index of bending strength), and buckling ratio (an index of cortical bone instability). We used a mathematical model to calculate the hip fracture distribution by femoral neck BMD, BMC, bone area, and hip structure analysis (HSA) parameters (cortical thickness, section modulus narrow neck width, and buckling ratio) and compared it with prospective data from the Rotterdam Study. In the prospective data, hip fracture cases in both sexes had lower BMD, thinner cortices, greater bone width, lower strength, and higher instability at baseline. In fractured individuals, men had an average BMD that was 0.09 g/cm(2) higher than women (p < 0.00001), whereas no significant difference in buckling ratios was seen. Modeled fracture distribution by BMD and buckling ratio levels were in concordance to the prospective data and showed that hip fractures seem to occur at the same absolute levels of bone instability (buckling ratio) in both men and women. No significant differences were observed between the areas under the ROC curves of BMD (0.8146 in women and 0.8048 in men) and the buckling ratio (0.8161 in women and 0.7759 in men). The buckling ratio (an index of bone instability) portrays in both sexes the critical balance between cortical thickness and bone width. Our findings suggest that extreme thinning of cortices in expanded bones plays a key role on local susceptibility to fracture. Even though the buckling ratio does not offer additional predictive value, these findings improve our understanding of why low BMD is a good predictor of fragility fractures.

Intestinal parasitic infections (IPIs) are still important to the health of Thai rural residents. IPIs are the cause of many chronic diseases with, for example, opisthorchiasis resulting in progression to cholangiocarcinoma (CCA). This cross-sectional study in a prospective cohort study aimed to examine the prevalence and co- infection of intestinal parasites among Northeastern Thai rural residents, recruited into the Khon Kaen Cohort Study (KKCS), and who were residing in areas of high-risk for developing CCA. On recruitment, subjects had completed questionnaires and provided fecal samples for IPI testing using the formalin ethyl acetate concentration technique. Data on selected general characteristics and the results of the fecal tests were analysed. IPI test results were available for 18,900 of cohort subjects, and 38.50% were found to be positive for one or more types of intestinal parasite. The prevalence of Opisthorchis viverrini (O. viverrini) infection was the highest (45.7%), followed by intestinal flukes (31.9%), intestinal nematodes (17.7%), intestinal protozoa (3.02%), and intestinal cestodes (1.69%). The pattern of different infections was similar in all age groups. According to a mapping analysis, a higher CCA burden was correlated with a higher prevalence of O. viverrini and intestinal flukes and a greater intensity of O. viverrini. Both prevention and control programs against liver fluke and other intestinal parasites are needed and should be delivered simultaneously. We can anticipate that the design of future control and prevention programmes will accommodate a more community-orientated and participatory approach.

Condom use and sexuality communication with adults: a study among high school students in South Africa and Tanzania

PubMed Central

2013-01-01

Background Fostering adolescents’ communication on sexuality issues with their parents and other significant adults is often assumed to be an important component of intervention programmes aimed at promoting healthy adolescent sexual practices. However, there are few studies describing the relationship between such communication and sexual practices, particularly in sub-Saharan Africa. This study examined the relationships between adolescents’ communication with significant adults and their condom use in three sites in this region. Methods Data stem from a multi-site randomized controlled trial of a school-based HIV prevention intervention implemented in Cape Town and Mankweng, South Africa and Dar es Salaam, Tanzania. Only data from comparison schools were used. The design is therefore a prospective panel study with three waves of data collections. Data were collected in 2004 from 6,251 participants in 40 schools. Associations between adolescents’ communication with adults about sexuality issues and their use of condoms were analysed cross-sectionally using analysis of variance, as well as prospectively using multiple ordinal logistic regression analysis. Results Cross-sectional analyses showed that consistent condom users had significantly higher mean scores on communication (across topics and communication partners) than both occasional users and never-users, who had the lowest scores. After controlling for condom use at the first data collection occasion in each model as well as for possible confounders, communication scores significantly predicted consistent condom use prospectively in all three ordinal logistic regression models (Model R2 = .23 to .31). Conclusion The findings are consistent with the assertion that communication on sexuality issues between adolescents and significant adults results in safer sexual practices, as reflected by condom use, among in-school adolescents. The associations between communication variables and condom use might have been stronger if we had measured additional aspects of communication such as whether or not it was initiated by the adolescents themselves, the quality of advice provided by adults, and if it took place in a context of positive adult-adolescent interaction. Studies with experimental designs are needed in order to provide stronger evidence of causality. PMID:24053420

Computational Methods of Studying the Binding of Toxins From Venomous Animals to Biological Ion Channels: Theory and Applications

Chen, Rong; Chung, Shin-Ho

2013-01-01

The discovery of new drugs that selectively block or modulate ion channels has great potential to provide new treatments for a host of conditions. One promising avenue revolves around modifying or mimicking certain naturally occurring ion channel modulator toxins. This strategy appears to offer the prospect of designing drugs that are both potent and specific. The use of computational modeling is crucial to this endeavor, as it has the potential to provide lower cost alternatives for exploring the effects of new compounds on ion channels. In addition, computational modeling can provide structural information and theoretical understanding that is not easily derivable from experimental results. In this review, we look at the theory and computational methods that are applicable to the study of ion channel modulators. The first section provides an introduction to various theoretical concepts, including force-fields and the statistical mechanics of binding. We then look at various computational techniques available to the researcher, including molecular dynamics, Brownian dynamics, and molecular docking systems. The latter section of the review explores applications of these techniques, concentrating on pore blocker and gating modifier toxins of potassium and sodium channels. After first discussing the structural features of these channels, and their modes of block, we provide an in-depth review of past computational work that has been carried out. Finally, we discuss prospects for future developments in the field. PMID:23589832

Objective to assess how informed patients are about breast reconstruction, and how involved they are in decision making. Summary Background Data Breast reconstruction is an important treatment option for patients undergoing mastectomy. Wide variations in who gets reconstruction, however, have led to concerns about decision making. Methods We conducted a prospective cross-sectional study of patients planning mastectomy at a single site, over 20 months. Before surgery, patients completed a survey with validated scales to assess knowledge about breast reconstruction and involvement in decision making. Factors associated with knowledge were examined in a multivariable linear regression model. Results 145 patients enrolled (77% enrollment rate), and 126 remained eligible. The overall knowledge score was 58.5% (out of 100%). Knowledge about risk of complications was especially low at 14.3%. Knowledge did not differ by treatment (reconstruction or not). On multivariable analysis, non-white race was independently associated with lower knowledge. Most patients (92.1%) reported some discussion with a provider about reconstruction, and most (90.4%) reported being asked their preference. More patients reported discussing the advantages of reconstruction (57.9%) than the disadvantages (27.8%). Conclusions Women undergoing mastectomy in this sample were highly involved in decision making but had major deficits in knowledge about the procedure. Knowledge about the risk of complications was particularly low. Providers appeared to have discussed the advantages of reconstruction more than its disadvantages. PMID:26727092

This study explored the effects of the diagnosis-related group (DRG)-based prospective payment system (PPS) operated by voluntarily participating organizations on the cesarean section (CS) rates, and analyzed whether the participating health care organizations had similar CS rates despite the varied participation periods. The study sample included delivery claims data from the Korean national health insurance program for the year 2003. Risk factors were identified and used in the adjustment model to distinguish the main reason for CS. Their risk-adjusted CS rates were compared by the reimbursement methods, and the organizations' internal and external environments were controlled. The final risk-adjustment model for the CS rates meets the criteria for an effective model. There were no significant differences of CS rates between providers in the DRG and fee-for-service system after controlling for organizational variables. The CS rates did not vary significantly depending on the providers' DRG participation periods. The results provide evidence that the DRG payment system operated by volunteering health care organizations had no impact on the CS rates, which can lower the quality of care. Although the providers joined the DRG system in different years, there were no differences in the CS rates among the DRG providers. These results support the future expansion of the DRG-based PPS plan to all health care services in Korea.

A wide range of environmental factors have been related to active ageing, but few studies have explored the impact of weather and day length on physical activity in older adults. We investigate the cross-sectional association between weather conditions, day length and activity in older adults using a population-based cohort in England, the European Prospective Investigation into Cancer and Nutrition (EPIC) Norfolk study. Physical activity was measured objectively over 7 days using an accelerometer and this was used to calculate daily total physical activity (counts per minute), daily minutes of sedentary behaviour and light, moderate and vigorous physical activity (LMVPA). Day length and two types of weather conditions, precipitation and temperature, were obtained from a local weather station. The association between these variables and physical activity was examined by multilevel first-order autoregressive modelling. After adjusting for individual factors, short day length and poor weather conditions, including high precipitation and low temperatures, were associated with up to 10% lower average physical activity (p<0.01) and 8 minutes less time spent in LMVPA but 15 minutes more sedentary time, compared to the best conditions. Day length and weather conditions appear to be an important factor related to active ageing. Future work should focus on developing potential interventions to reduce their impact on physical activity behaviours in older adults.

Encountering patients who are fearful and anxious is common in dental practice and these factors can increase the complexity of dental procedures. A prospective cohort study was performed to assess whether patient anxiety influences the difficulty of impacted lower third molar extraction and to identify other predictive factors of surgical difficulty; 102 extractions done under local anaesthesia were assessed. Several preoperative variables were recorded (demographic, anatomical, and surgical) and patient anxiety was assessed through the use of various questionnaires. Extraction difficulty was measured using the operation time (OT) and a 100-mm visual analogue scale (difficulty VAS) completed by the surgeon. Patients with deep impacted third molars that required bone removal and tooth sectioning showed higher levels of preoperative anxiety. Significant correlations were found between questionnaire scores and the surgical difficulty (OT and difficulty VAS). OT was also related to age, depth of impaction, third molar angulations, proximity of the third molar roots to the mandibular canal, hard and soft tissue coverage, and the need to perform an ostectomy and tooth sectioning. Impacted lower third molar extraction is significantly more difficult in anxious patients. Other demographic, radiological, and surgical factors were also found to be significantly related to the surgical difficulty.

2018-01-01

Context Increased use of contraceptives in Malawi has not translated into a commensurate reduction in fertility, but the reason is unknown. Insight into contraceptive switching and discontinuation may shed light on this conundrum and on whether the commonly used modern contraceptive prevalence rate (mCPR) is the best indicator of family planning program performance. Methods A one-year prospective longitudinal data set was created from patient-held family planning cards of 4,678 reproductive-age women living in a demographic surveillance site in rural northern Malawi. Contraceptive service data recorded on the women’s cards by providers were linked to their socioeconomic, demographic and health data. Contraceptive point prevalence estimates calculated from these data were compared with mCPR estimates from cross-sectional surveys. Survival analyses examined contraceptive adherence. Results The contraceptive point prevalence of 35% was slightly lower than comparable cross-sectional estimates of mCPR. Only 51% of users of the injectable—the most widely used modern method—received their first reinjection on time, and just 15% adhered to the method for 12 months. Although various study variables were associated with contraceptive use, none were associated with adherence. Conclusions Gaps in and discontinuation of use of the injectable may play a role in the discrepancy between mCPR and fertility. Interventions to help women adhere to injectable use and to promote long-acting methods should be strengthened. PMID:26600568

Purpose Amputation is a life changing event that can significantly impact an individual's physical and mental well-being. Our objective was to review literature exploring the impact of amputation upon a person's functioning and inclusion in the workplace. Methods Medline, CINAHL, and PsycINFO were searched using keywords related to amputation, employment and community reintegration. Eligible studies were published since 2000 and one of the following study designs: randomized controlled trial, non-randomized controlled trial, retrospective study, prospective study, concurrent cohort study, or cross sectional study. Studies for civilians with amputation as well as service members and Veterans with amputation were considered for inclusion. Results The search identified 995 articles, 25 of which met inclusion/exclusion criteria and were included in the review. While strong evidence for correlations and predictors of outcomes after amputation were limited, multiple factors were identified as contributing to physical functioning and employment after amputation. Conclusions Outcomes after amputation can vary widely with many potentially inter-related factors contributing. The factors identified may also serve to inform the development of interventions aiming to improve functional performance and reintegration after amputation. Furthermore, the review highlights the need for more high quality prospective studies.

One of the most frequent indications for cesarean section is dystocia. It is impossible to predict, difficult to identify and coincident with the rapid expiry of the expected time, so it is important to point out some mistakes in expecting vaginal delivery. The aim of this study was to examine the frequency and the length of dystocia-related cesarean delivery, as well as the vitality of the newborn immediately after birth. A prospective 3-year study was conducted including a total number of 6470 deliveries regardless of whether they were completed using cesarean section after an unsuccessful attempt of spontaneous vaginal delivery or not. The Apgar score, a proved useful tool for the assessment of the vitality of newborn children in the first minute, was used. On the basis of the established indications, 653 (10.10%) of deliveries were completed using cesarean section. Dystocia was the third most common indication for cesarean section (16.38%). Deliveries in which dystocia was established as a diagnosis lasted much longer (p = 0.030) which resulted in weaker vitality of newborn children (p = 0.000) compared to the deliveries ended by spontaneous vaginal delivery. This study shows that deliveries caused by dystocia last much longer and newborn children are of weaker vitality compared to other deliveries caused not by dystocia. Decisions concerning cesarean section must be made in a timely fashion.

Conduct problems and peer effects are among the strongest risk factors for adolescent substance use and problem use. However, it is unclear to what extent the effects of conduct problems and peer behavior interact, and whether adolescents' capacity to refuse the offer of substances may moderate such links. This study was conducted to examine relationships between conduct problems, close friends' substance use, and refusal assertiveness with adolescents' alcohol use problems, tobacco, and marijuana use. We studied a population-based sample of 1,237 individuals from the Cardiff Study of All Wales and North West of England Twins aged 11-18 years. Adolescent and mother-reported information was obtained. Statistical analyses included cross-sectional and prospective logistic regression models and family-based permutations. Conduct problems and close friends' substance use were associated with increased adolescents' substance use, whereas refusal assertiveness was associated with lower use of cigarettes, alcohol, and marijuana. Peer substance use moderated the relationship between conduct problems and alcohol use problems, such that conduct problems were only related to increased risk for alcohol use problems in the presence of substance-using friends. This effect was found in both cross-sectional and prospective analyses and confirmed using the permutation approach. Reduced opportunities for interaction with alcohol-using peers may lower the risk of alcohol use problems in adolescents with conduct problems.

The authors conducted a cross-sectional and prospective longitudinal study of stress, coping, and psychological symptoms in children of divorce. The sample consisted of 258 children (mean age = 10.1; SD = 1.2), of whom 196 were successfully followed 5.5 months later. A 4-dimensional model of coping was found using confirmatory factor analysis, with the factors being active coping, avoidance, distraction, and support. In the cross-sectional model avoidance coping partially mediated the relations between negative events and symptoms while active coping moderated the relations between negative events and conduct problems. In the longitudinal model significant negative paths were found from active coping and distraction Time 1 to internalizing symptoms Time 2, while Time 1 support coping had a positive path coefficient to Time 2 depression. Positive paths were found between negative events at Time 1 and anxiety at Time 2, and between all symptoms at Time 1 and negative events at Time 2.

Obstructive sleep apnea (OSA), typically manifested as snoring, is closely associated with obesity. However, the directionality of associations of OSA with cardiometabolic risk markers is unclear, as obesity increases risk for OSA, and OSA results in excess weight gain and its metabolic consequences. Less is known about how obesity and OSA may relate in children and adolescents and whether maternal OSA may influence the development of obesity and cardiometabolic dysfunction in offspring. Among 1078 children from the Project Viva cohort, we examined cross-sectionally and prospectively associations of parent-reported child or maternal snoring with cardiometabolic outcomes, including adiposity, adipokines, and insulin resistance. Cross-sectionally, child snoring was related to adiposity and metabolic risk, particularly body mass index (BMI; β 0.61kg/m 2 , 95% CI 0.33, 0.89; p<0.001), trunk fat mass index (β 0.23kg/m 2 , CI 0.12, 0.34; p<0.001), high-density lipoprotein cholesterol (β -1.47mg/dL, CI -2.69, -0.25; p=0.02), and metabolic risk z-score (β 0.08, CI 0.02, 0.14; p=0.01) after correction for covariates. Prospectively, adiposity (BMI, trunk fat, fat mass, and waist circumference) and cardiometabolic (leptin, HOMA-IR, CRP, and global metabolic risk) measures at mid-childhood (~7y) were associated with child snoring at the early teen visit (~12y) after correction for covariates. Child snoring at ~9y was related to changes in adiposity between mid-childhood and early teen visits. Child but not maternal snoring, was related to child adiposity and cardiometabolic outcomes. Adiposity and child snoring are associated with each other cross-sectionally and are each predictive of the other among children/adolescents prospectively. These results suggest similar mechanisms in pediatric/adolescent populations as in adults for the development of sleep-disordered breathing and sleep apnea that will need to be confirmed in randomized clinical trials. Importantly, this research points to the need to target both sleep and obesity in order to break this vicious cycle. Copyright © 2017 Elsevier Inc. All rights reserved.

To study the relationship of self-esteem and personality factors with eating disorders (ED). A region-wide representative sample of 2862 girls 12-21 years old from Navarre (Spain) participated in the baseline assessment of a prospective study. A two-stage procedure was used, consisting in a first screening phase followed by a psychiatrist interview (DSM-IV criteria). Multivariable logistic regression models were used to examine the association of self-esteem (36-item scale) and personality characteristics (Eysenck inventory) with psychiatrist-diagnosed ED while controlling for potential confounders. Strong associations for ED were found with low self-esteem (adjusted odds ratio [adjOR] for the lowest quartile: 7.98, 95% CI: 3.4-18.8) and high levels of neuroticism (adjOR for the highest quartile: 9.49, 95% Cl: 3.7-24.5). Our results, although based on a cross-sectional design, support the potential role of neuroticism and low self-esteem in the onset of ED. Copyright 2002 by Wiley Periodicals, Inc.

Several publications have measured the difficulty of third molar removal, trying to establish the main risk factors, however several important preoperative and intraoperative variables are overlooked. A prospective cohort study comprising a total of 130 consecutive lower third molar extractions was performed. The outcome variables used to measure the difficulty of the extraction were operation time and a 100mm visual analogue scale filled by the surgeon at the end of the surgical procedure. The predictors were divided into 4 different groups (demographic, anatomic, radiographic and operative variables). A descriptive, bivariate and multivariate analysis of the data was performed. Patients' weight, the presence of bulbous roots, the need to perform crown and root sectioning of the lower third molar and Pell and Gregory 123 classification significantly influenced both outcome variables (p< 0.05). Certain anatomical, radiological and operative variables appear to be important factors in the assessment of surgical difficulty in the extraction of lower third molars.

2013-03-01

A strong positive association between emotion regulation difficulties (ERD) and posttraumatic stress symptoms (PTSS) has been consistently evidenced in cross-sectional research. However, a lack of prospective research has limited hypotheses regarding the temporal relationship between trauma exposure, ERD, and PTSS. The present prospective study investigated the role of pre-trauma difficulties with emotion regulation in the development of PTSS following exposure to a potentially traumatic event. Between Time 1 (T1) and Time 2 (T2), a mass shooting occurred at the participants' (n=691) university campus. ERD and PTSS were assessed prior to the shooting (T1), in the acute aftermath of the shooting (T2), and approximately eight months later (T3). Using a cross-lagged panel design, ERD was found to prospectively predict PTSS from T1 to T2 and T2 to T3. Additionally, PTSS prospectively predicted ERD from T1 to T2. However, T2 PTSS failed to predict T3 PTSS. Results indicate that ERD and PTSS are reciprocally influential from pre- to post-shooting. Further, results suggest that emotion dysregulation in the aftermath of a potentially traumatic event influences one's ability to recover from PTSS over time, even after accounting for the effects of existing symptomatology. To examine the specificity of temporal relations between ERD and PTSS a second cross-lagged panel design, in which a general distress construct was substituted for PTSS, was conducted. Results of this analysis, as well as conceptual and clinical implications, will be discussed. Copyright © 2013 Elsevier Ltd. All rights reserved.

Description of mothers' characteristics, obstetricians' practices, and PPROM-linked mortality in all 81 maternity hospitals in the Rhône-Alpes Region, over a period of 2 years. Prospective cohort study of 598 women with PPROM between 24 and 34 weeks' gestation, leading to 680 births. At time of PPROM, collection of mothers' socio-economic characteristics, medical and obstetric histories and PPROM circumstances. Collection of perinatal management, neonates' medical status and postnatal referral. The birth rate after PPROM between 24 and 34 weeks' gestation was 0.47% (95% CI: 0.42-0.48). Sixty percent of PPROM occurred before 32 weeks' gestation and 98% of births before 37 weeks. The incidence of previous PPROM was 14.3%. Antibiotics, corticosteroids, and tocolytics were given to 82, 78, and 52% of women, respectively. The rate of antibiotics and antenatal corticosteroids varied with gestational age (lower rates for antibiotics just after the limit of viability (23-24 weeks) and after 32 weeks, higher rates of corticosteroids between 26 and 30 weeks). The PPROM-birth interval became shorter as gestation advanced. The incidence of C-section was 58.7% (n = 270), C-section before labour being the most frequent mode of delivery. Sixty-seven percent of neonates were born in Level-3 hospitals. The overall neonatal mortality rate at 28 days decreased with gestational age at PPROM, and was 17.2% (16/93), 3% (6/200), and 0.41% (1/241) at 24-27, 28-31 and 32-33 weeks of PPROM, respectively. After PPROM, antibiotics and antenatal corticosteroids were widely used in our cohort, and C-section rates were elevated. With that up-to-date management, the perinatal mortality rate was less than 3% following PPROM after 28 weeks' gestation.

Several cross-sectional studies have examined factors associated with support for tobacco control policies. The current study utilized a longitudinal design to test smoking status and attitude toward smoking measured in adolescence as prospective predictors of support for tobacco control policies measured in adulthood. Participants (N = 4,834) were from a longitudinal study of a Midwestern community-based sample. Hierarchical multiple regression analyses tested adolescent smoking status and attitude toward smoking as prospective predictors (after controlling for sociodemographic factors, adult smoking status, and adult attitude toward smoking) of support for regulation of smoking in public places, discussion of the dangers of smoking in public schools, prohibiting smoking in bars, eliminating smoking on television and in movies, prohibiting smoking in restaurants, and increasing taxes on cigarettes. Participants who smoked during adolescence demonstrated more support for discussion of the dangers of smoking in public schools and less support for increasing taxes on cigarettes but only among those who smoked as adults. Those with more positive attitudes toward smoking during adolescence demonstrated less support as adults for prohibiting smoking in bars and eliminating smoking on television and in movies. Moreover, a significant interaction indicated that those with more positive attitudes toward smoking as adolescents demonstrated less support as adults for prohibiting smoking in restaurants, but only if they became parents as adults. This study's findings suggest that interventions designed to deter adolescent smoking may have future benefits in increasing support for tobacco control policies.

Background Notification of sugammadex has been supplemented with a section on hemostasis, including a longer clotting time in the first minutes following injection, without any documented clinical consequences. The objective of this observational study was to analyze the effects of sugammadex administration on routine coagulation tests and bleeding in the clinical setting. Methods After Institutional Review Board approval, a prospective observational study was conducted between January and December 2011. Adult patients scheduled for laparotomies were analyzed in groups according to the type of reversal (without sugammadex versus 2 or 4 mg/kg sugammadex). There were no changes in our current clinical practice. Blood samples drawn from these patients were standardized at the same time and tested using the same daily calibrated machine. The endpoint was a comparison of the activated partial thromboplastin time (aPTT), prothrombin time (PT), hemoglobin (Hb) level and hematocrit (Ht), immediately before sugammadex administration (H0) and 1 h after neuromuscular block reversal (H1). Results One hundred and forty-two patients in three groups were included as follows: 11 in the "without sugammadex" group, 64 in the "2 mg/kg sugammadex" group and 67 in the "4 mg/kg sugammadex" group. Results did not differ significantly among the groups. Conclusions In this prospective observational study, the use of 2 and 4 mg/kg sugammadex was not associated with a longer clotting time or decreased hemoglobin concentrations. Future prospective investigations should study patients receiving 16 mg/kg sugammadex and/or with abnormal coagulation tests. PMID:25664150

To evaluate the effect of a novel communication tool, related to the degree of urgency for Caesarean sections (CSs), on the decision-to-delivery interval for emergency CS. Red CS are very urgent cases corresponding to life-threatening maternal or foetal situations, orange CS are urgent cases and green CS are non-urgent intrapartum CS. We carried out this cohort study in a French maternity hospital. The study included all emergency Caesarean sections during two 6-month periods, before and after introduction of the code. We compared the decision-to-delivery interval of the two study periods. Our study included 174 emergency CS. The mean decision-to-delivery interval after introduction of the code was 31.7 min, significantly shorter (p=0.02) than the 39.6 min interval before introduction of the colour code. Except for the preparation time, each time interval decreased. This included transporting the patient into the operating theatre, and the incision-to-delivery time interval. This study suggests that the use of the three-colour code could significantly shorten the decision-to-delivery interval in emergency CS. Further prospective studies are needed to confirm this result.

This map is a modified version of Geological map and map of useful minerals, Shaida area, scale 1:50,000, which was compiled by V.I. Tarasenko, N.I. Borozenets, and others in 1973. Scientists from the U.S. Geological Survey, in cooperation with the Afghan Geological Survey and the Task Force for Business and Stability Operations of the U.S. Department of Defense, studied the original document and related reports and also visited the field area in August 2010.This modified map illustrates the geological structure of the Shaida copper-lead-zinc deposit and Misgaran copper-lead-zinc prospect in western Afghanistan and includes cross sections of the same area. The map reproduces the topology (contacts, faults, and so forth) of the original Soviet map and cross sections and includes modifications based on our examination of these documents and on observations made during our field visit. Elevations on the cross sections are derived from the original Soviet topography and might not match the newer topography used on the current map. We have attempted to translate the original Russian terminology and rock classification into modern English geologic usage as literally as possible without changing any genetic or process-oriented implications in the original descriptions. We also use the age designations from the original map.The unit colors on the map and cross sections differ from the colors shown on the original version. The units are colored according to the color and pattern scheme of the Commission for the Geological Map of the World (CGMW) (http://www.ccgm.org).

To investigate the effect of implementation of a number of process policy guidelines (protocol), on the success rate of external cephalic version (ECV) for breech presentation. Prospective study. During a 3-year period (2004-2006) a standardized protocol for an ECV consultation was developed, evaluated and adapted. After implementing this modified protocol as 'process policy guidelines', the effect on the rate of successful ECV was prospectively evaluated during the period 1 January 2007-31 July 2008. Success was defined as cephalic presentation (ultrasound) immediately after ECV. A secondary outcome measure was the elective caesarean section rate for breech presentation. The rate of successful ECV increased significantly from 47% (110/236 pregnant women) in the period January 2004-December 2006 to 61% (85/139, p = 0.006) in the period January 2007-July 2008. Patient characteristics were similar in both groups, with the exception of 2 subgroups of term of version. The increase was preferentially found in nulliparous and multiparous women with frank breech. Nulliparity, frank breech, anterior placenta and low birth weight were associated with a lower success rate of ECV. The term of pregnancy at which ECV was performed did not seem to affect the success rate. Implementing the process policy guidelines increased the number of cephalic presentations at delivery and decreased the rate of elective caesarean sections for breech presentation from 39% to 27% (p = 0.03). The number needed to treat to prevent 1 elective caesarean section by ECV according to the process policy guidelines was 8. After implementation of the process policy guidelines, the success rate of ECV increased considerably. The rate of elective caesarean section for breech presentation declined. These findings are in favour of establishing specialized ECV centres in the Netherlands.

Beneficial effects of vegetarian and vegan diets on health outcomes have been supposed in previous studies. Aim of this study was to clarify the association between vegetarian, vegan diets, risk factors for chronic diseases, risk of all-cause mortality, incidence, and mortality from cardio-cerebrovascular diseases, total cancer and specific type of cancer (colorectal, breast, prostate and lung), through meta-analysis. A comprehensive search of Medline, EMBASE, Scopus, The Cochrane Library, and Google Scholar was conducted. Eighty-six cross-sectional and 10 cohort prospective studies were included. The overall analysis among cross-sectional studies reported significant reduced levels of body mass index, total cholesterol, LDL-cholesterol, and glucose levels in vegetarians and vegans versus omnivores. With regard to prospective cohort studies, the analysis showed a significant reduced risk of incidence and/or mortality from ischemic heart disease (RR 0.75; 95% CI, 0.68 to 0.82) and incidence of total cancer (RR 0.92; 95% CI 0.87 to 0.98) but not of total cardiovascular and cerebrovascular diseases, all-cause mortality and mortality from cancer. No significant association was evidenced when specific types of cancer were analyzed. The analysis conducted among vegans reported significant association with the risk of incidence from total cancer (RR 0.85; 95% CI, 0.75 to 0.95), despite obtained only in a limited number of studies. This comprehensive meta-analysis reports a significant protective effect of a vegetarian diet versus the incidence and/or mortality from ischemic heart disease (-25%) and incidence from total cancer (-8%). Vegan diet conferred a significant reduced risk (-15%) of incidence from total cancer.

Symptoms of both depression and Post-Traumatic Stress Disorder (PTSD) are prevalent among first-time mothers following birth. However, the direction of the association between the two types of symptoms is unclear. Ninety six first-time mothers giving birth via vaginal delivery (N=38), emergency C-Section (N=27) and planned C-Section (N=21) were assessed for depression and PTSD twice: Six weeks post-partum and six-weeks later. Cross-lagged Structural Equation Modeling (SEM) analyses revealed a prospective effect of depressive symptoms on PTSD symptoms. No moderating factors were identified. A relatively modest sample size and only two assessment waves. An early detection and intervention with symptoms of post-partum depression might also prevent the development of PTSD symptoms.

Prospects for DVCS measurements using the COMPASS spectrometer at CERN

NASA Astrophysics Data System (ADS)

Kouznetsov, O.

2011-07-01

The study of exclusive reactions like Deeply Virtual Compton Scattering (DVCS) and Deeply Virtual Meson Production (DVMP) is one major part of the future COMPASS program to investigate nucleon structure through Generalized Parton Distributions (GPD). The high energy of the muon beam allows to measure the xBj-dependence of the t-slope of the DVCS cross section and to study nucleon tomography. The use of positive and negative polarized muon beams allows to determine the Beam Charge and Spin Difference of the DVCS cross sections to access the real part of the Compton form factor related to the dominant GPD H. As a second phase a transversely polarized proton target will be used to collect data to constrain the GPD E. In preparation of the future measurements two DVCS test runs were performed in 2008 and 2009.

The effects of a new constructivist science curriculum (PIPS) for prospective elementary teachers

NASA Astrophysics Data System (ADS)

Liang, Ling L.

This study examines the effectiveness of a new constructivist curriculum model (Powerful Ideas in Physical Science, PIPS) in promoting preservice teachers' understanding of science concepts, in fostering a learning environment supporting conceptual change, and in improving preservice teachers' attitudes toward science as well as their science teaching efficacy beliefs. The PIPS curriculum model integrates a conceptual change perspective with a hands-on, inquiry-based approach and other promising effective teaching strategies such as cooperative learning. Three instructors each taught one class section using the PIPS and one using the existing curriculum for an introductory science course. Their students were 121 prospective elementary teachers at a large mid-western university. ANCOVA and Repeated Measures Analyses of Variance were performed to analyze the scores on concept tests and attitude surveys. Data from videotaped observations of lab sessions and interviews of prospective teachers and their instructors were analyzed by employing a naturalistic inquiry method to get insights into the process of science learning and teaching for the prospective teachers. The interpretations were made based on the findings that could be corroborated by both methodologies. For the twelve prospective teachers interviewed, it was found that the PIPS model was more effective in promoting conceptual understanding and positive attitudes toward science learning for those with lower past science performance. The PIPS approach left more room for self-reflection on the development of understanding of science concepts in contrast to the lecture-lab type teaching. Factors that might have influenced the teacher trainees' attitudes and beliefs about learning and teaching science were identified and discussed. It was also found that better cooperative learning and a more supportive learning environment have been promoted in the PIPS classrooms. However, the differential treatment effects on learning outcomes for all participants of the study, as measured by the paper-pencil instruments, were not statistically significant. Both students' and instructors' perspectives of the PIPS approach are presented in the study. Limitations of the present study as well as recommendations for future revision of the PIPS curriculum and effective implementation of the constructivist teaching in general, are also included.

Symptoms and the use of wireless communication devices: A prospective cohort study in Swiss adolescents

DOE Office of Scientific and Technical Information (OSTI.GOV)

Schoeni, Anna, E-mail: anna.schoeni@unibas.ch

Background: We investigated whether radiofrequency electromagnetic fields (RF-EMF) from mobile phones and other wireless devices or by the wireless device use itself due to non-radiation related factors in that context are associated with an increase in health symptom reports of adolescents in Central Switzerland. Methods: In a prospective cohort study, 439 study participants (participation rate: 36.8%) aged 12–17 years, completed questionnaires about their mobile and cordless phone use, their self-reported symptoms and possible confounding factors at baseline (2012/2013) and one year later (2013/2014). Operator recorded mobile phone data was obtained for a subgroup of 234 adolescents. RF-EMF dose measures consideringmore » various factors affecting RF-EMF exposure were computed for the brain and the whole body. Data were analysed using a mixed-logistic cross-sectional model and a cohort approach, where we investigated whether cumulative dose over one year was related to a new onset of a symptom between baseline and follow-up. All analyses were adjusted for relevant confounders. Results: Participation rate in the follow-up was 97% (425 participants). In both analyses, cross-sectional and cohort, various symptoms tended to be mostly associated with usage measures that are only marginally related to RF-EMF exposure such as the number of text messages sent per day (e.g. tiredness: OR:1.81; 95%CI:1.20–2.74 for cross-sectional analyses and OR:1.87; 95%CI:1.04–3.38 for cohort analyses). Outcomes were generally less strongly or not associated with mobile phone call duration and RF-EMF dose measures. Conclusions: Stronger associations between symptoms of ill health and wireless communication device use than for RF-EMF dose measures were observed. Such a result pattern does not support a causal association between RF-EMF exposure and health symptoms of adolescents but rather suggests that other aspects of extensive media use are related to symptoms. - Highlights: • This is a prospective cohort study with approximately one year of follow-up. • Self-reported and operator recorded mobile phone use data were collected. • The cumulative RF-EMF dose for the brain and for the whole body was calculated. • Associations were stronger for the use of wireless devices than for RF-EMF dose. • This suggests that rather aspects of extensive media use than RF-EMF are related to symptoms.« less

The origins and persistence of psychological morbidity in caregivers are not fully understood. The present analysis examined the relationship between the strain and burden of caregiving and depression and anxiety in a large community sample. Social support and sleep quality were investigated as potential mediators. Cross-sectional and prospective observational study. Individuals caring for someone other than their own child (N=393) were identified from a population of 2,079. Caregiving strain and burden, social support, and sleep quality were assessed. Participants completed the hospital anxiety and depression scale at the same time and 5 years later. Caregiving strain and burden were associated with depression and anxiety symptoms cross-sectionally, and with a worsening of symptoms 5 years later. Sleep quality appeared to mediate the cross-sectional relationships. The demands of caregiving and associated sleep disruption contribute to symptoms of depression and anxiety in caregivers.

Low self-esteem and depression are strongly correlated in cross-sectional studies, yet little is known about their prospective effects on each other. The vulnerability model hypothesizes that low self-esteem serves as a risk factor for depression, whereas the scar model hypothesizes that low self-esteem is an outcome, not a cause, of depression. To test these models, the authors used 2 large longitudinal data sets, each with 4 repeated assessments between the ages of 15 and 21 years and 18 and 21 years, respectively. Cross-lagged regression analyses indicated that low self-esteem predicted subsequent levels of depression, but depression did not predict subsequent levels of self-esteem. These findings held for both men and women and after controlling for content overlap between the self-esteem and depression scales. Thus, the results supported the vulnerability model, but not the scar model, of self-esteem and depression.

Burnout (BO) is increasingly considered a public health problem: it is not only harmful to the individual, but also for the organization. Therefore, in recent years, research has given particular attention to the study of the phenomenon and its antecedents among the nursing profession. In the last ten years, the literature shows the prevalence of BO in different clinical settings, but there are few recent data describing the phenomenon and its relationship with educational preventive programs. The aims of this study are: a) to describe the prevalence of nurses' risk of BO in the northern Italy area b) to describe nurses' coping and their perception of the BO antecedents. c) to describe the effects of education on the nurses' coping and their recognition of BO antecedents. The study is structured into two main parts. The first was cross-sectional, the second was prospective. Burnout Potential Inventory (BPI) questionnaire was used in the cross-sectional part to survey risk of BO in three big hospitals in Northern Italy. The Health Profession Stress and Coping Scale (HPSCS) was used in the prospective part to survey the nurses' stress perception and their coping mechanisms in a post-graduate educational program. Nurses' BO risk is within the normal range, although the BPI highlighted three borderline subscales: poor team work, work overload and poor feedback. Post-graduate education had a positive effect on the stress perception, but it is not sufficient to improve coping mechanisms. The study revealed the more stressful work situations and the effect of post-graduate education to prevent the effects of stress. This topic needs further investigation in the light of the result of this study.

Background Non-thyroidal illness syndrome (NTIS) is a characteristic functional constellation of thyrotropic feedback control that frequently occurs in critically ill patients. Although this condition is associated with significantly increased morbidity and mortality, there is still controversy on whether NTIS is caused by artefacts, is a form of beneficial adaptation, or is a disorder requiring treatment. Trials investigating substitution therapy of NTIS revealed contradictory results. The comparison of heterogeneous patient cohorts may be the cause for those inconsistencies. Objectives Primary objective of this study is the identification and differentiation of different functional states of thyrotropic feedback control in order to define relevant evaluation criteria for the prognosis of affected patients. Furthermore, we intend to assess the significance of an innovative physiological index approach (SPINA) in differential diagnosis between NTIS and latent (so-called "sub-clinical") thyrotoxicosis. Secondary objective is observation of variables that quantify distinct components of NTIS in the context of independent predictors of evolution, survival or pathophysiological condition and influencing or disturbing factors like medication. Design The approach to a quantitative follow-up of non-thyroidal illness syndrome (AQUA FONTIS study) is designed as both a cross-sectional and prospective longitudinal observation trial in critically ill patients. Patients are observed in at least two evaluation points with consecutive assessments of thyroid status, physiological and clinical data in additional weekly observations up to discharge. A second part of the study investigates the neuropsychological impact of NTIS and medium-term outcomes. The study design incorporates a two-module structure that covers a reduced protocol in form of an observation trial before patients give informed consent. Additional investigations are performed if and after patients agree in participation. Trial Registration ClinicalTrials.gov NCT00591032 PMID:18851740

This study aimed to compare the vitamin D status in healthy Moroccan men and women aged 50 years and older. A total of 186 Moroccan women and 68 men, who had no previous diagnosis of osteoporosis, were recruited prospectively. We found in this study a high prevalence of hypovitaminosis D with no difference between men and women. The main purpose of this study was to describe and compare the vitamin D status, parathormone, calcium, and phosphate of healthy Moroccan men and women aged 50 years and older. We conducted two cross-sectional studies, in postmenopausal women from October 2008 to November 2009 and in men over 50 years old, from December 2009 to August 2010. A total of 186 Moroccan women and 68 men, who had no previous diagnosis of osteoporosis, were recruited prospectively. For the definition of hypovitaminosis D, the preferred level for 25-hydroxyvitamin D (25(OH)D) insufficiency, which is now recommended by many experts, is 30 ng/mL (75 nmol/L), and the levels below 10 ng/ml (25 nmol/L) indicate deficiency. The prevalence of vitamin D deficiency in men and women was 4.4 and 8.6 %, respectively, and the prevalence of vitamin D(25(OH) D) insufficiency in men and women were 85.2 and 77.4 %, respectively. In men and women, no correlations were found between intact parathormone (PTHi) and 25(OH) D (r = 0.056). Despite a sunny environment, we found in this study a high prevalence of hypovitaminosis D (insufficiency + deficiency) in Moroccan men over 50 years old and postmenopausal women.

Nutritional and body weight recommendations for cardiovascular diseases are well established, yet there are no equivalent guidelines for peripheral arterial disease (PAD). This cross-sectional study measured the prevalence of cardiovascular-related nutritional and body composition risk factors in sixty PAD patients and their association with PAD severity. A diet that exceeds daily recommended intake of fat and that falls short of recommended intakes of fiber, folate, and vitamin D was associated with increased leg pain and walking difficulty. Increased body fat and waist circumference were associated with diminished walking ability and poorer psychosocial quality of life. Future prospective investigations are merited to inform both PAD clinical care and disease management guidelines.

Design of hybrid two-dimensional and three-dimensional nanostructured arrays for electronic and sensing applications

NASA Astrophysics Data System (ADS)

Ko, Hyunhyub

This dissertation presents the design of organic/inorganic hybrid 2D and 3D nanostructured arrays via controlled assembly of nanoscale building blocks. Two representative nanoscale building blocks such as carbon nanotubes (one-dimension) and metal nanoparticles (zero-dimension) are the core materials for the study of solution-based assembly of nanostructured arrays. The electrical, mechanical, and optical properties of the assembled nanostructure arrays have been investigated for future device applications. We successfully demonstrated the prospective use of assembled nanostructure arrays for electronic and sensing applications by designing flexible carbon nanotube nanomembranes as mechanical sensors, highly-oriented carbon nanotubes arrays for thin-film transistors, and gold nanoparticle arrays for SERS chemical sensors. In first section, we fabricated highly ordered carbon nanotube (CNT) arrays by tilted drop-casting or dip-coating of CNT solution on silicon substrates functionalized with micropatterned self-assembled monolayers. We further exploited the electronic performance of thin-film transistors based on highly-oriented, densely packed CNT micropatterns and showed that the carrier mobility is largely improved compared to randomly oriented CNTs. The prospective use of Raman-active CNTs for potential mechanical sensors has been investigated by studying the mechano-optical properties of flexible carbon nanotube nanomembranes, which contain freely-suspended carbon nanotube array encapsulated into ultrathin (<50 nm) layer-by-layer (LbL) polymer multilayers. In second section, we fabricated 3D nano-canal arrays of porous alumina membranes decorated with gold nanoparticles for prospective SERS sensors. We showed extraordinary SERS enhancement and suggested that the high performance is associated with the combined effects of Raman-active hot spots of nanoparticle aggregates and the optical waveguide properties of nano-canals. We demonstrated the ability of this SERS substrate for trace level sensing of nitroaromatic explosives by detecting down to 100 zeptogram (˜330 molecules) of DNT.

Cross-sectional analyses on a consecutive, prospective cohort. To evaluate the ability of the Scoliosis Research Society (SRS)-Schwab Adult Spinal Deformity Classification to group patients by widely used health-related quality-of-life (HRQOL) scores and examine possible confounding variables. The SRS-Schwab Adult Spinal Deformity Classification includes sagittal modifiers considered important for HRQOL and the clinical impact of the classification has been validated in patients from the International Spine Study Group database; however, equivocal results were reported for the Pelvic Tilt modifier and potential confounding variables were not evaluated. Between March 2013 and May 2014, all adult spinal deformity patients from our outpatient clinic with sufficient radiographs were prospectively enrolled. Analyses of HRQOL variance and post hoc analyses were performed for each SRS-Schwab modifier. Age, history of spine surgery, and aetiology of spinal deformity were considered potential confounders and their influence on the association between SRS-Schwab modifiers and aggregated Oswestry Disability Index (ODI) scores was evaluated with multivariate proportional odds regressions. P values were adjusted for multiple testing. Two hundred ninety-two of 460 eligible patients were included for analyses. The SRS-Schwab Classification significantly discriminated HRQOL scores between normal and abnormal sagittal modifier classifications. Individual grade comparisons showed equivocal results; however, Pelvic Tilt grade + versus +  + did not discriminate patients according to any HRQOL score. All modifiers showed significant proportional odds for worse aggregated ODI scores with increasing grade levels and the effects were robust to confounding. However, age group and aetiology had individual significant effects. The SRS-Schwab sagittal modifiers reliably grouped patients graded 0 versus + / +  + according to the most widely used HRQOL scores and the effects of increasing grade level on odds for worse ODI scores remained significant after adjusting for potential confounders. However, effects of age group and aetiology should not be neglected. 3.

2013-01-01

Background Cognitive complaints involving problems with concentration, memory, decision-making and thinking are relatively common in the work force. The sensitivity of both subjective and objective cognitive functioning to common psychiatric conditions, stress levels and to cognitive load makes it plausible that psychosocial working conditions play a role in cognitive complaints. Thus, this study aimed to test the associations between psychosocial work factors and cognitive complaints in nationally representative samples of the Swedish work force. Cross-sectional (n = 9751) and prospective (n = 3644; two time points two years apart) sequential multiple regression analyses were run, adjusting for general confounders, depressive- and sleeping problems. Additional prospective analyses were run adjusting for baseline cognitive complaints. Cross-sectional results High quantitative demands, information and communication technology (ICT) demands, underqualification and conflicts were positively associated with cognitive complaints, while social support, good resources at work and overqualification were negatively associated with cognitive complaints in all models. Skill discretion and decision authority were weakly associated with cognitive complaints. Conflicts were more strongly associated with cognitive complaints in women than in men, after adjustment for general confounders. Prospective results Quantitative job demands, ICT demands and underqualification were positively associated with future cognitive complaints in all models, including when adjusted for baseline cognitive complaints. Decision authority was weakly positively associated with future cognitive complaints, only after adjustment for depressive- and sleeping problems respectively. Social support was negatively associated with future cognitive complaints after adjustment for general confounders and baseline cognitive complaints. Skill discretion and resources were negatively associated with future cognitive complaints after adjustment for general confounders. The associations between quantitative demands and future cognitive complaints were stronger in women. Discussion/Conclusions The findings indicate that psychosocial working conditions should be taken into account when considering cognitive complaints among employees. PMID:23560101

Is bilingualism associated with a lower risk of dementia in community-living older adults? Cross-sectional and prospective analyses.

The aim of this study was to determine whether bilingualism is associated with dementia in cross-sectional or prospective analyses of older adults. In 1991, 1616 community-living older adults were assessed and were followed 5 years later. Measures included age, sex, education, subjective memory loss (SML), and the modified Mini-mental State Examination (3MS). Dementia was determined by clinical examination in those who scored below the cut point on the 3MS. Language status was categorized based upon self-report into 3 groups: English as a first language (monolingual English, bilingual English) and English as a Second Language (ESL). The ESL category had lower education, lower 3MS scores, more SML, and were more likely to be diagnosed with cognitive impairment, no dementia at both time 1 and time 2 compared with those speaking English as a first language. There was no association between being bilingual (ESL and bilingual English vs. monolingual) and having dementia at time 1 in bivariate or multivariate analyses. In those who were cognitively intact at time 1, there was no association between being bilingual and having dementia at time 2 in bivariate or multivariate analyses. We did not find any association between speaking >1 language and dementia.

Point and Click, Carefully: Investigating Inconsistent Response Styles in Middle School and College Students Involved in Web-Based Longitudinal Substance Use Research

This study investigated inconsistent responding to survey items by participants involved in longitudinal, web-based substance use research. We also examined cross-sectional and prospective predictors of inconsistent responding. Middle school (N = 1,023) and college students (N = 995) from multiple sites in the United States responded to online surveys assessing substance use and related variables in three waves of data collection. We applied a procedure for creating an index of inconsistent responding at each wave that involved identifying pairs of items with considerable redundancy and calculating discrepancies in responses to these items. Inconsistent responding was generally low in the Middle School sample and moderate in the College sample, with individuals showing only modest stability in inconsistent responding over time. Multiple regression analyses identified several baseline variables—including demographic, personality, and behavioral variables—that were uniquely associated with inconsistent responding both cross-sectionally and prospectively. Alcohol and substance involvement showed some bivariate associations with inconsistent responding, but these associations largely were accounted for by other factors. The results suggest that high levels of carelessness or inconsistency do not appear to characterize participants’ responses to longitudinal web-based surveys of substance use and support the use of inconsistency indices as a tool for identifying potentially problematic responders.

Background The relation between plasma lipid levels and Alzheimer disease (AD) and vascular dementia (VaD), and the impact of drugs to lower lipid levels remains unclear. Objective To investigate the relation between plasma lipid levels and the risk of AD and VaD and the impact of drugs to lower lipid levels on this relationship. Design and Setting Cross-sectional and prospective community-based cohort studies. Participants Random sample of 4316 Medicare recipients, 65 years and older, residing in northern Manhattan, NY. Main Outcome Measures Vascular dementia and AD according to standard criteria. Results Elevated levels of non–high-density lipoprotein (HDL-C) and low-density lipoprotein cholesterol (LDL-C) and decreased levels of HDL-C were weak risk factors for VaD in either cross-sectional or prospective analyses. Higher levels of total cholesterol were associated with a decreased risk of incident AD after adjustment for demographics, apolipoprotein E genotype, and cardiovascular risk factors. Treatment with drugs to lower lipid levels did not change the disease risk of either disorder. Conclusions We found a weak relation between non–HDL-C, LDL-C, and HDL-C levels and the risk of VaD. Lipid levels and the use of agents to lower them do not seem to be associated with the risk of AD. PMID:15148148

Plasma bicarbonate and odds of incident hypertension.

2013-12-01

Several biomarkers of metabolic acidosis, including lower plasma bicarbonate, have been associated with prevalent hypertension in cross-sectional studies. We sought to examine prospectively whether lower plasma bicarbonate is associated with incident hypertension. We conducted a prospective case-control study nested within the Nurses' Health Study II. Plasma bicarbonate was measured in 695 nonobese women without hypertension at time of blood draw who subsequently developed hypertension during 6 years of follow-up. Control subjects were matched to case subjects according to age, race, time and day of blood draw, and day of menstrual cycle. We used unconditional logistic regression to generate odds ratios (ORs) for development of hypertension by quintile of baseline plasma bicarbonate. After adjusting for matching factors, body mass index, family history of hypertension, plasma creatinine, and dietary and lifestyle factors, higher plasma bicarbonate was associated with lower odds of developing hypertension across quintiles (P for linear trend = 0.04). Those in the highest compared with the lowest quintile of plasma bicarbonate had 31% lower odds of developing hypertension (OR = 0.69; 95% confidence interval = 0.48-0.99). Further adjustment for diet-estimated net endogenous acid production, plasma insulin, 25-hydroxyvitamin D, and uric acid did not alter these findings. Our case-control study is consistent with a modest association between higher plasma bicarbonate and reduced odds of developing hypertension among nonobese women, although our findings are of borderline statistical significance. Further research is required to confirm this finding as part of a larger prospective cohort study and to elucidate the mechanism for this relation.

The detection of single tumor cells or tumor cell clusters represents an important issue in intraoperative frozen section analysis. For example, surgical margins may be evaluated in order to minimize the number of additional operations. Furthermore, intraoperative diagnosis of lymph node micrometastasis (LNM) may help to define the area of appropriate lymph node dissection. In addition to haematoxylin and eosin (H&E)-stained sections, immunohistochemical detection of single tumor cells or cell clusters may be helpful in this context. The aim of this study was to evaluate the clinical significance, reliability and sensitivity of intraoperative rapid immunostaining of frozen sections. Therefore, we compared the results of rapid immunohistochemical staining of frozen sections and paraffin sections applying the EnVision and Histofine(R) detection systems. In a prospective immunohistochemical study, paraffin and frozen sections of 20 gastric cancer specimens were analyzed. Paraffin as well as frozen sections were stained immunohistochemically applying the EnVision and Histofine detection systems. As primary antibodies, AE1/AE3 (anti-cytokeratin), EMA (anti-MUC1) and B lymphocyte marker anti-CD20 were applied. The rapid immunostaining procedure was able to be completed within 10-13 min. Rapid immunohistochemical staining of frozen and paraffin sections of the same tumors resulted in comparable immunoreactivity. The rapid EnVision and Histofine procedures allowed immunostaining of frozen sections in less than 13 min. These methods can represent useful additional tools in routine surgical pathology and research, enabling a more accurate frozen section diagnosis compared to staining with H&E alone. Intraoperative rapid immunostaining can be a simple and useful technique to detect LNM.

Metastasis size in melanoma sentinel lymph nodes (SLNs) is an emerging prognostic factor. Two European melanoma treatment trials include SLN metastasis diameters as inclusion criteria. Whilst diameter estimates are sensitive to the number of sections examined, the level of this bias is largely unknown. We performed a prospective multicentre study to compare the European Organisation for Research and Treatment of Cancer (EORTC) recommended protocol with a protocol of complete step-sectioning. One hundred and thirty-three consecutive SLNs from seven SLN centres were analysed by five central sections 50μm apart (EORTC Protocol) followed by complete 250μm step-sectioning. Overall, 29 patients (21.8%) were SLN-positive. The EORTC Protocol missed eight of these metastases (28%), one metastasis measuring less than 0.1mm in diameter, seven measuring between 0.1 and 1mm. Complete step-sectioning at 250μm intervals (Extensive Protocol) missed one metastasis (3%) that measured less than 0.1mm. Thirteen treatment courses (34%) performed if inclusion was based on the Combined Protocol would not be performed if assessed by the EORTC Protocol. Thus, 10 patients would be without completion lymph node dissection (EORTC MINITUB study), whilst three patients would not be eligible for anti-CTLA4 trial (EORTC protocol 18071). The corresponding number with the Extensive Protocol would be three; one patient for the MINITUB registration study and two patients for the anti-CTLA4 study. Examining SLNs by close central sectioning alone (EORTC Protocol) misses a substantial number of metastases and underestimates the maximum metastasis diameter, leading to important changes in patient eligibility for various treatment protocols.

Rates of breastfeeding initiation in hospitals with a tertiary neonatal intensive care unit are limited. A follow-up study with prospectively collected data in a Danish university hospital with approximately 5000 annual births was conducted. Between 1 February 2015 and 30 June 2015, 1939 newborns were enrolled in the study. Rates of frequencies for initiation of breastfeeding were calculated. High initiations rates for breastfeeding were found among term-born infants. Newborns of multiparous women had the highest initiation rate of 91.7% and newborns delivered by cesarean section had the lowest initiation rate of 73.3%. Copyright © 2017 Elsevier B.V.

The aim of this study was to evaluate the advantages of the Misgav Ladach surgical technique compared to traditional cesarean section. A prospective randomized trial of 111 women undergoing cesarean section was carried out in the Pula General Hospital. Forty-nine operations were performed using the Pfannenstiel method of cesarean section, 55 by the Misgav Ladach method and 7 by lower midline laparotomy. It was proved that the cases where the Misgav Ladach method was implemented, compared to the Pfannenstiel method, showed a significantly shorter delivery/extraction and operative time (P=0.0009), the incision pain on the second postoperative day was significantly lower (0.021), we recorded a quicker stand up and walking time (P=0.013), significantly fewer analgesic injections and a shorter duration of analgesia were required (P=0.0009) and the bowel function was restored to normal sooner (P=0.001). The Misgav Ladach method of cesarean section has advantages over the Pfannenstiel method in so far as it is significantly quicker to perform, with diminished postoperative pain and less use of postoperative analgesics. The recovery of physiologic function is faster. No differences were found in intraoperative bleeding, maternal morbidity, scar appearance, uterus postoperative involution and the assessment of the inflammation response to the operative technique.
