    This study examined sex differences in money beliefs and behaviours. Over 100,000 British participants completed two measures online, one of which assessed "money pathology" (Forman in Mind over money, Doubleday, Toronto, 1987), and the other four "money types", based on the emotional associations of money (Furnham et al. in Personal Individ Differ, 52:707-711, 2012). Nearly all measures showed significant sex differences with medium to large effect sizes, and with females exhibiting more "money pathology" than males. The biggest difference on the money types was on money being associated with generosity (money representing love) where men scored much lower than females, and autonomy (money representing freedom) where men scored higher than women. For men, more than women, money represented Power and Security. Men were more likely to be Hoarders while women did more emotional regulatory purchasing. Implications and limitations of this study are discussed.

    Many studies report a female predominance in the prevalence of chronic musculoskeletal pain (CMP) but the mechanisms explaining these sex differences are poorly understood. Data from a random postal questionnaire survey in the Dutch general population were used to examine whether sex differences in

    This study investigated gender differences in symptom profiles of major depressive disorder (MDD) in the Korean general population. Data were pooled from the series of nationwide Korean Epidemiologic Catchment Area surveys conducted in 2001, 2006 and 2011, respectively. Of the 18,807 participants, 507 (397 women and 110 men) were diagnosed with MDD within the prior 12 months. In agreement with previous studies, women with MDD appeared to be more vulnerable to experiencing atypical depressive episodes defined as depression with two or more symptoms of fatigue, increased appetite and hypersomnia (P differences in symptomatology of MDD in the general Korean population, and the results are comparable to previous investigations from western societies. Assumingly, the intercultural similarity in female preponderance to atypical depression might reflect the common biological construct underlying the gender difference in mechanism of MDD. In clinical settings, gender differences of MDD should be carefully considered, because these features could be related with treatment response and drug side effects.

    Understanding the timing and length of the growth spurt of Class III prognathic patients is fundamental to the strategy of interceptive orthopedic orthodontics as well as to the timing of orthognathic surgery. Consequently, this study was undertaken to determine whether there are any significant differences in the stature growth pattern of Class III subjects compared with non-Class III subjects and the general population. Twelve-year longitudinal stature growth data were collected for 402 randomly selected adolescents in the general population, 55 Class III mandibular prognathic patients, and 37 non-Class III patients. The growth data were analyzed by using the traditional linear interpolation method and nonlinear growth functions. The 6 stature growth parameters were measured: age at takeoff, stature at takeoff, velocity at takeoff, age at peak height velocity, stature at peak height velocity, and velocity at peak height velocity. Comparisons in the stature growth parameters and 15 cephalometric variables among the general population, Class III subjects, and non-Class III subjects were made with multivariate analysis. Patients with Class III prognathism did not have different growth parameters compared with Class II subjects or the general population. This study does not allow meaningful conclusions with regard to the relationship of mandibular size and stature growth pattern. The application of nonlinear growth curves vs the traditional linear interpolation method was also discussed. Copyright © 2012 American Association of Orthodontists. Published by Mosby, Inc.

    The objective of the study was to investigate interarm differences of blood pressure (BP) and its determinants, and to clarify whether both arms are equally good in assessing BP and target organ damage in the general population. We studied a representative sample of Finnish adult population with 484 study participants, ages 25-74 years. BP was measured twice by an oscillometric monitor simultaneously on both arms. Study participants underwent a clinical examination including measurements of serum lipids, glucose and indicators of target organ damage. BP was 2.3/0.2 mmHg higher on right than on left arm (P differences). SBP and DBP measured on right and left arms correlated equally with left ventricular mass index (LVMI), interventricular septal thickness (IVST), posterior wall thickness (PWT), pulse wave velocity (PWV) and albuminuria. Higher SBP level was an independent determinant of both greater systolic and diastolic interarm BP difference. Exaggerated absolute diastolic interarm BP difference (>5 mmHg) was associated with higher BMI, arm circumference, LVMI, IVST and PWT, whereas exaggerated absolute systolic interarm BP difference (>10 mmHg) was not associated with any clinical variables. There was only a small difference in BP between arms in a healthy general population. Both arms are equally good determinants of target organ damage. BP should be measured at least once on both arms and prefer the arm with higher BP readings in the future BP measurements.

    Full Text Available Aim: Heart disease and emotional disorders often co-occur, but effective role in dysregulation of heart disease that is often overlooked. Evidence suggests that people with heart disease are more problems in regulating their emotions. The study compared the re-evaluation of cognitive emotion regulation commonly used two strategies- and suppression- between heart disease and the general population. Methods: Sixty men (30 with heart complaints and 30 without the condition were selected by convenience sampling method and they responded to the Emotion Regulation Questionnaire (Gross and John and a demographic questionnaire responded. To analyze the results and descriptive statistics such as frequency tables and inferential statistics, independent T-test was used SPSS software was used. Results: The result shows that heart disease and general population re-evaluation strategies groups (P<0.01. This is not only different from the strategy reassessment, but in different repression, too. (P <0.001. Conclusion: The results showed that heart disease and general population used different strategies to regulate their emotions. The key to finding the heart disease group prefer repression to regulate their emotions.

    Abstract Introduction Globally, the number of immigrants is rising every year, so that the number of immigrants worldwide is estimated at 200 million. In Slovenia, immigrants comprise 6.5% of the overall population. Immigrants bring along to a foreign country their cultural differences and these differences can affect immigrants’ overall health status and lead to chronic health conditions. The aim of this study was to identify patients’ perception of general practitioners’ (GPs’) attitudes toward immigrants in Slovenia. Methods This study was based on the Qualicopc questionnaire. We used the questions that targeted patients’ experience with the appointment at their GP on the day that the study was carried out. Results There were no differences in GPs’ accessibility based on groups included in our study (p>0.05). Compared to the non-immigrant population, first-generation immigrants answered that their GPs were impolite (p=0.018) and that they did not take enough time for them (p=0.038). In addition, they also experienced more difficulties understanding their GP’s instructions (p<0.001). Second-generation immigrants experienced more negative behaviour from GPs, and first-generation immigrants had more difficulties understanding GPs’ instructions. Conclusion There may be some differences in patients’ perception of GPs’ attitudes towards immigrants in comparison with the general Slovenian population. However, based on the perception of the immigrants that do benefit from the medical care it is not possible to judge the GPs’ attitudes towards immigrants as worse compared to their attitude towards the non-immigrant population. Indeed, there may be other reasons why the patients answered the way they did. PMID:27703534

    Two methodological criticisms have limited the reliability and validity of findings from previous studies that seek to examine change across the life span in levels of internalizing psychopathology using general population surveys. The first criticism involves the potential influence of cohort effects that confound true age-related changes whereas the second criticism involves the use of a single form of assessment to measure and compare levels of internalizing psychopathology. This study seeks to address these criticisms by modeling age-related change using multiple measures and multiple surveys. Data from 2 epidemiological surveys conducted 10 years apart in the Australian general population were combined and used for the current study. The latent construct of internalizing psychopathology was modeled using a combination of Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) depression and anxiety diagnoses as well as items from the Kessler Psychological Distress scale (K10; Kessler et al., 2002). Confirmatory factor analysis (CFA) indicated that a single internalizing dimension provided good model fit to the data. Multigroup CFA indicated that strict measurement invariance of the model can be assumed across survey administrations and age bands, justifying comparisons of mean differences in latent trait levels. Significant changes in mean levels of latent internalizing psychopathology were evident between respondents aged 30-39 years old in 1997 and respondents aged 40-49 years old in 2007, suggesting a minor but significant increase in psychopathology across middle age. By contrast, a minor but significant decrease in psychopathology was noted when transitioning from late middle age (50-59 years old) to old age (60-69 years old). The majority of individuals in the general population will experience constant levels of internalizing psychopathology as they age, suggesting that the construct is relatively

    The population-based study examined postulated effects, derived from a resources-demands-model about gender-related aspects of self-efficacy, optimism, chronic stress, and exhaustion. Data acquisition was carried out by a market research institute with a multi-topic questionnaire in the general population (N = 2,552). Instruments administered were the Questionnaire for Self-Efficacy and Optimism, the Trier Inventory for Chronic Stress, and the Chalder-Fatigue-Scale. Households and target persons were selected randomly. The analyses focused on structural equation modeling. There were significant differences in structural relations among the resource paths. In particular, significant gender differences were found with respect to self-efficacy, and among the exhaustion paths, namely in the mental dimension of exhaustion. The observed measures of chronic stress were found to be operating equivalently for both genders. Results suggest that resources play an important role in the understanding of how chronic stress is preceded and may lead to exhaustion in both genders. Personal resources seem to be more expressed by men than by woman, for whom the relation of resources to health is of greater importance than for men.

    General self-efficacy (GSE) refers to optimistic self-beliefs of being able to perform and control behaviors, and is linked with various physical and mental health outcomes. Measures of self-efficacy are commonly used in health research with clinical populations, but are less explored in relationship to sociodemographic characteristics in general populations. This study investigated GSE in relation to sociodemographic characteristics in the general population in Norway. As part of a larger national survey, the GSE scale was administered to a general population sample, and 1787 out of 4961 eligible participants (response rate 36%) completed the scale. Group comparisons were conducted using independent t-tests and one-way analyses of variance. Linear regression analysis was used to examine factors independently associated with GSE. GSE was lower for older compared to younger participants ( p employment were independently associated with higher GSE. Age moderated the associations between gender and employment on one hand, and GSE on the other. The association between being male and having higher GSE was more pronounced in younger age, as was the association between being employed and having higher GSE. Male gender and being employed were related to higher GSE among persons in the general population in Norway, and these associations were stronger among persons of younger age. The findings are considered fairly representative for the Norwegian population.

    We investigated the inter-arm difference in blood pressure of the general Korean population to identify associated factors. A total of 806 participants aged 30 to 64 years without history of major cardiovascular disease were analyzed in this cross-sectional study. They participated in the Cardiovascular and Metabolic Disease Etiology Research Center cohort study that began in 2013. Brachial blood pressure was measured simultaneously for both arms using an automated oscillometric device equipped with two cuffs in seated position. After five minutes of rest, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured three times. The average of the three measurements was used for analysis. Multivariate logistic regression models were used to identify factors associated with inter-arm differences in blood pressure. The mean inter-arm difference was 3.3 mmHg for SBP and 2.0 mmHg for DBP. Large inter-arm differences (≥10 mmHg) in SBP and in DBP were found in 3.7% and 0.9% of subjects, respectively. A large inter-arm difference in SBP was associated with mean SBP (p=0.002) and C-reactive protein (p=0.014) while a large inter-arm different in DBP was only associated with body mass index (p=0.015). Sex, age, and anti-hypertensive medication use were not associated with differences in inter-arm blood pressure. Large inter-arm difference in blood pressure is only present in a small portion of healthy Korean adults. Our findings suggest that high SBP, chronic inflammation, and obesity may be associated with larger difference in inter-arm blood pressure.

    Poor social support and lack of social network are well-established risk factors for morbidity and mortality in general populations. Good social relations, such as social support and network contacts, are associated with better self-management and fewer psychosocial problems in persons with type 2 diabetes. The aim of this study was to investigate whether persons with type 2 diabetes have poorer social relations than the general population. We conducted a cross-sectional survey in three settings: a specialist diabetes clinic (SDC) (n = 1084), a web panel (WP) consisting of persons with type 2 diabetes (n = 1491) and a sample from the 2010 Danish Health and Morbidity Survey, representative of the general population (n = 15,165). We compared social relations using multivariate logistic regression. Compared to the general population, persons with type 2 diabetes more often lived without a partner (SDC, OR 1.75, 95% CI 1.49-2.06; WP, OR 1.64, 95% CI 1.43-1.87), met with family less than once a month (SDC, OR 1.78, 95% CI 1.40-2.27; WP, OR 2.35, 95% CI 1.94-2.84) and were less certain they could count on help from others in case of illness (WP, OR 1.23, 95% CI 1.08-1.41). Our findings suggest that persons with type 2 diabetes have poorer social relations than the general population. From a public health point of view, special attention is needed with regards to strengthening existing networks and establishing alternative networks among persons with type 2 diabetes.

    Full Text Available Background-There are marked sex differences in cardiovascular disease [CVD] manifestation. It is largely unknown how the distribution of CVD risk factors or intermediate phenotypes explain sex-specific differences.Methods and Results-In 5000 individuals of the population-based Gutenberg Health Study, mean age 55±11 years, 51% males, we examined sex-specific associations of classical CVD risk factors with intima-media thickness, ankle-brachial index, flow-mediated dilation, peripheral arterial tonometry, echocardiographic and electrocardiographic variables. Intermediate cardiovascular phenotypes were related to prevalent CVD (coronary artery disease, heart failure, stroke, myocardial infarction, lower extremity artery disease [LEAD] N=561.We observed differential distributions of CVD risk factors with a higher risk factor burden in men. Manifest coronary artery disease, stroke, myocardial infarction and LEAD were more frequent in men; the proportion of heart failure was higher in women. Intermediate phenotypes showed clear sex differences with more beneficial values in women. Fairly linear changes towards less beneficial values with age were observed in both sexes. In multivariable-adjusted regression analyses age, systolic blood pressure and body mass index were consistently associated with intermediate phenotypes in both sexes with different ranking according to random forests, maximum model R² 0.43. Risk factor-adjusted associations with prevalent CVD showed some differences by sex. No interactions by menopausal status were observed. Conclusions-In a population-based cohort we observed sex differences in risk factors and a broad range of intermediate phenotypes of noninvasive cardiovascular structure and function. Their relation to prevalent CVD differed markedly. Our results indicate the need of future investigations to understand sex differences in CVD manifestation.

    HIV/AIDS (Human immunodeficiency virus/Acquired immune deficiency syndrome) not only has a strong impact on the health of the worldwide population but also affects the labour status of HIV-positive people. The primary aim of this paper is to compare the labour participation of people living with HIV (PlwHIV) with the labour participation of the general population along the last business cycle in Spain. The data used are from the Hospital Survey on HIV-AIDS, with a total sample size of 4,651 PlwHIV and the Labour Force Survey from 2001 to 2010, with a total sample size of 660,674 individuals as general population. Propensity Score Matching method was used to analyse the differences between the labour participation of PlwHIV and the general population. Additionally, several specific models categorised into different subgroups (gender, education, source of infection and level of defences) were also performed. We identified a convergence in labour participation across the period in the two populations considered: PlwHIV was 23% less likely to have a job than the general population during 2001-2002 and 14% less likely during 2009-2010. This convergence is mainly explained by two facts: first, the positive evolution of people infected by sex; second, the change in the PlwHIV population composition with a decreasing weight of people infected by drug use throughout the decade. Thereby, at the end of period, there was no statistical difference in the employment rate between PlwHIV infected through sex and the general population but there was strongly difference in PlwHIV infected through drugs. Inmunological status, source of infection and level of education play a relevant role among the PlwHIV population when comparing their labour participation with the general population. In spite of this positive result, the likelihood of being employed in HIV-positive people continues to be different from that of non-carriers. Our study shows that institutional features of labour

    Full Text Available This general population-based study examined associations between violence and mental health, musculoskeletal pain, and early disability pension. The prevalence and consequences of good vs. poor adjustment (resilience vs. vulnerability following encounters with violence were also examined. Data were based on the sixth wave of the "Tromsø Study" (N = 12,981; 65.7% response rate, 53.4% women, M-age = 57.5 years, SD-age = 12.7 years. Self-reported data on psychological (threats and physical violence (beaten/kicked, mental health (anxiety/depression, musculoskeletal pain (MSP, and granting of disability pension (DP were collected. Men suffered more violent events during childhood than women did, and vice versa during adulthood. Psychological violence implied poorer mental health and slightly more MSP than physical violence. The risk of MSP was highest for violence occurring during childhood in women and during the last year for men. A dose-response relationship between an increasing number of violent encounters and poorer health was observed. About 58% of individuals reported no negative impact of violence (hence, resilience group, whereas 42% considered themselves as more vulnerable following encounters with violence. Regression analyses indicated comparable mental health but slightly more MSP in the resilience group compared to the unexposed group, whereas the vulnerable group had significantly worse health overall and a higher risk of early granting of DP. Resilience is not an all-or-nothing matter, as physical ailments may characterize individuals adapting well following encounters with violence.

    Gallbladder polyps (GBP) are a common clinical finding that can express malignant potential. The aim of this study was to evaluate whether vegetarianism protects against GBP, together with other putative risk factors. A retrospective, cross-sectional study was conducted with subjects who received a health check-up from July 2005 to December 2011. Korean Buddhist priests, who are obligatory vegetarians by religious belief, were identified as vegetarians (vegetarian group) and compared with a non-vegetarian control group sampled from those coming for health check-ups at the same institution. Out of 18,483 subjects, GBP were found in 810 (4.4%). Al though GBP tended to be less common in the vegetarian group (23 [3.5%] out of 666) than in control group (787 [4.4%] out of 17,817), the difference was insignificant statistically (p=0.233). By logistic regression, old age (OR=1.61, 95% CI=1.1 9-2.26 for 30-39 years; OR=1.47, 95% CI=1.08-1.98 for 40-49 years), male gender (OR=1.51, 95% CI=1.31-1.75), high BMI (OR=1.18, 95% CI=1.00-1.39 for ≥ 23.0 kg/m(2) and vegetarianism.

    The aim of this study was to determine whether the austerely living Trappist and Benedictine monks have a lower prevalence of a number of risk factors and health problems than the general Dutch population. A written questionnaire was submitted to monks of 7 monasteries. The response was 67 per cent (134 monks). The data were compared with data from the national Health Interview Survey of 1989, which used an almost identical questionnaire. Adjustment was made for differences in age and education. Monks consume less alcohol and tobacco and have a more austere diet. Their average Quetelet index is lower. The prevalence of cardiovascular disease is lower. On the other hand, monks more often report a number of other chronic diseases, physical complaints, and problems with activities of daily life. They more often have contact with general practitioners and with consultants. The lower prevalence of a number of risk factors among monks reflects their austere way of life. It is not certain whether the lower prevalence of cardiovascular diseases can be attributed to this way of life. The fact that, in general, health problems are more prevalent among monks suggests that changes in lifestyle do not necessarily lead to compression of morbidity.

    Due to the problems of measurement and the lack of nationally representative data, the extent of compulsive buying behaviour (CBB) is relatively unknown. The validity of three different instruments was tested: Edwards Compulsive Buying Scale (ECBS; Edwards, E.A., 1993. Development of a new scale for measuring compulsive buying behaviour. Financial Counseling and Planning. 4, 67-85), Questionnaire About Buying Behavior (QABB; Lejoyeux, M., Ades, J., 1994. Les achats pathologiques: une addiction comportementale. Neuro-Psy. 9, 25-32.) and Richmond Compulsive Buying Scale (RCBS; Ridgway, N.M., Kukar-Kinney, M., Monroe, K.B., 2008. An expanded conceptualization and a new measure of compulsive buying. Journal of Consumer Research. 35, 622-639.) using two independent samples. One was nationally representative of the Hungarian population (N=2710) while the other comprised shopping mall customers (N=1447). As a result, a new, four-factor solution for the ECBS was developed (Edwards Compulsive Buying Scale Revised (ECBS-R)), and confirmed the other two measures. Additionally, cut-off scores were defined for all measures. Results showed that the prevalence of CBB is 1.85% (with QABB) in the general population but significantly higher in shopping mall customers (8.7% with ECBS-R, 13.3% with QABB and 2.5% with RCBS-R). Conclusively, due to the diversity of content, each measure identifies a somewhat different CBB group. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Sleep, fish consumption, and depression have a close relationship; however, the role of sex differences in sleep, fish consumption, and depression research is not yet well-established. This study aimed to examine whether the impact of bedtime, sleep-onset latency, sleep duration, sleep quality, and fish consumption on depressive symptoms differed in women and men. An online survey was conducted in South Korea with a stratified random sample of 600 participants between the ages of 20 and 69, whose gender and age were proportional to estimates of Korea's general population. The 20-item Center for Epidemiologic Studies Depression Scale was used to measure depressive symptoms with a cut-off score of 16. The Pittsburgh Sleep Quality Index (PSQI) was applied to evaluate sleep timing, sleep-onset latency, sleep duration, and sleep quality. Our results indicated that late bedtime and short sleep duration were independently associated with depressive symptoms in women. Sleep-onset latency and poor sleep quality were independently associated with increased prevalence of depressive symptoms in both men and women. Higher fish consumption was significantly associated with decreased prevalence of depressive symptoms in men only. Our findings suggested the importance of a different approach for men and women in terms of promoting healthy sleep habits. In addition, higher fish consumption may be beneficial in the primary prevention of depression in Korean men. Further research is needed to confirm the findings from this cross-sectional study.

    Health states can be valued by those who currently experience a health state (experienced health states [EHS]) or by the general public, who value a set of given health states (GHS) described to them. There has been debate over which method is more appropriate when making resource allocation decisions. This article informs this debate by assessing whether differences between these methods have an effect on the mean EQ-5D-3L tariff scores of different patient groups. The European tariff based on GHS valuations was compared with a German EHS tariff. Comparison was made in the context of EQ-5D-3L health states describing a number of diagnosed chronic diseases (stroke, diabetes, myocardial infarction, and cancer) taken from the Cooperative Health Research in the Augsburg Region population surveys. Comparison was made of both the difference in weighting of the dimensions of the EQ-5D-3L and differences in mean tariff scores for patient groups. Weighting of the dimensions of the EQ-5D-3L were found to be systematically different. The EHS tariff gave significantly lower mean scores for most, but not all, patient groups despite tariff scores being lower for 213 of 243 EQ-5D-3L health states using the GHS tariff. Differences were found to vary between groups, with the largest change in difference being 5.45 in the multiple stoke group. The two tariffs have systematic differences that in certain patient groups could drive the results of an economic evaluation. Therefore, the choice as to which is used may be critical when making resource allocation decisions. Copyright © 2014 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

    To advance the understanding of health-related quality of life among older nursing home residents by assessing their health-related quality of life and comparing this with norms from the general population. The study used a two-group cross-sectional comparative design. The samples comprised 227 nursing home residents aged 65-102 years with at least six months' residence and a representative population sample of 1137 Norwegian citizens aged 65-102 years. All nursing home residents had a Clinical Dementia Rating Scale score > or =0.5 and were capable of conversing. The respondents provided demographic information and were surveyed using the SF-36 Health Survey. We used univariate and multivariate linear models to identify possible differences in health-related quality of life between the nursing home residents and the general population, controlled for age, sex, marital status and education. After adjustment for age, group, sex, marital status and education, the nursing home residents scored significantly higher on bodily pain and on physical and emotional role limitation and significantly lower on the other SF-36 subscales, except social functioning, with the largest differences for physical functioning (mean nursing home 23.2 and mean general population 62.9). The general population scores on all subscales generally increased with increasing education but not among the nursing home residents. The mean SF-36 scale scores differed markedly between the nursing home residents and the general population, with the nursing home residents generally scoring lower. The association with background variables known to be related to health-related quality of life differed between the groups. Healthcare professionals should increase attention to health-related quality of life among nursing home residents, periodically assess health-related quality of life and consider interventions that may improve health-related quality of life in older institutionalised populations.

    Throughout the literature, substantial evidence supports associations between poor psychosocial work characteristics and a variety of ill-health outcomes. Yet, few reports strategies workers carry out to improve detrimental work conditions and consequently their health, such as changing jobs. The aim of this study was to examine if adverse psychosocial work exposure, as measured with the job demand-control and effort-reward imbalance models, could predict job mobility over a 5 years observation period. Participants were working men and women (n = 940; 54.3% women), aged 24-60 years from the population of Gothenburg and surrounding metropolitan area. Job demand-control and effort-reward variables were compared with independent t-tests and chi2-test in persons with and without job mobility. Multivariate logistic regression was used to analyse whether psychosocial factors could predict job mobility. All regression analyses were stratified by gender. Exposure to a combination of high demands-low control or high imbalance between effort and reward was related to increased odds of changing jobs (OR 1.63; CI 1.03-2.59 and OR 1.46; CI 1.13-1.89 respectively). When analysing men and women separately, men had a higher OR of changing jobs when exposed to either high demands-low control (OR 2.72; CI 1.24-5.98) or high effort-reward imbalance (OR 1.74; CI 1.11-2.72) compared to reference values. The only significant associations for women was slightly decreased odds for turnover in high reward jobs (OR 0.96; CI 0.92-0.99). The results indicate that workers will seek to improve poor work environment by changing jobs. There were notable gender differences, where men tended to engage in job mobility when exposed to adverse psychosocial factors, while women did not. The lack of measures for mechanisms driving job mobility was a limitation of this study, thus preventing conclusions regarding psychosocial factors as the primary source for job mobility.

    To investigate the effect of capsaicin cream on the secretion of the submandibular gland (SMG) and the parotid gland (PG) in the general population, with different chilli-eating habits. In two groups with different chilli-eating habits, the salivary flow rate of the SMG and the PG was detected at statics and different times, after application of capsaicin cream. In both groups, the topical application of capsaicin cream could significantly increase the salivary secretion of SMG (P 0.05). On the other hand, although the salivary flow rate of PG also increased after stimulation, the increase had no statistical difference (P > 0.05). The application of capsaicin cream can effectively promote the secretion of the SMG and the PG, and its effect is independent of chilli-eating habits, which indicates that topical application of capsaicin cream can be considered as a potential treatment for the hypofunction of the salivary gland.

    Objective: Population studies have shown coronary calcium score to improve risk stratification in subjects suspected for cardiovascular disease. The aim of this work was to assess the validity of multidetector computed tomography (MDCT) for measurement of calibrated mass scores (MS) in a phantom study, and to investigate inter-scanner variability for MS and Agaston score (AS) recorded in a population study on two different high-end MDCT scanners. Materials and methods: A calcium phantom was scanned by a first (A) and second (B) generation 320-MDCT. MS was measured for each calcium deposit from repeated measurements in each scanner and compared to known physical phantom mass. Random samples of human subjects from the Copenhagen General Population Study were scanned with scanner A (N = 254) and scanner B (N = 253) where MS and AS distributions of these two groups were compared. Results: The mean total MS of the phantom was 32.9 ± 0.8 mg and 33.1 ± 0.9 mg (p = 0.43) assessed by scanner A and B respectively – the physical calcium mass was 34.0 mg. Correlation between measured MS and physical calcium mass was R{sup 2} = 0.99 in both scanners. In the population study the median total MS was 16.8 mg (interquartile range (IQR): 3.5–81.1) and 15.8 mg (IQR: 3.8–63.4) in scanner A and B (p = 0.88). The corresponding median total AS were 92 (IQR: 23–471) and 89 (IQR: 40–384) (p = 0.64). Conclusion: Calibrated calcium mass score may be assessed with very high accuracy in a calcium phantom by different generations of 320-MDCT scanners. In population studies, it appears acceptable to pool calcium scores acquired on different 320-MDCT scanners.

    To assess whether there is a natural difference in blood pressure (BP) measurements between the right and left arms, and to identify what factors are associated with this difference in a general population. The study subjects were 1090 individuals who participated in a medical check-up in Ohasama, Japan. The BP was measured simultaneously in both arms, using an automated device. The inter-arm BP difference was expressed as the relative difference [right-arm BP (R) minus left-arm BP (L): R - L] and the absolute difference (|R - L|). The relationship between inter-arm difference and various factors was analyzed using univariate analysis. The characteristics of subjects in whom the absolute systolic BP (SBP) difference was greater than 10 mmHg were analyzed using multivariate logistic analysis. The relative differences in SBP and diastolic BP (DBP) were -0.6 +/- 6.6 (mean +/- SD) and 1.1 +/- 4.7 mmHg, while the absolute differences were 4.9 +/- 4.4 and 3.7 +/- 3.0 mmHg. The absolute SBP difference was found to correlate significantly with age, body mass index, ankle-brachial index (ABI), and hypertension. Subjects with hypertension, hypercholesterolemia, obesity, elevated hemoglobin A1c (HbA1c) and low ABI had a significant and independent increase in the risk of an absolute SBP difference greater than 10 mmHg. The results suggest that there is considerable difference in the measured BP in the right and left arms and that large differences in the absolute SBP are associated with risk factors for arteriosclerosis such as hypertension, hypercholesterolemia, obesity, metabolic abnormalities and low ABI.

    Full Text Available Purpose: To find the most accurate mathematical description of the intravaginal ejaculation latency time (IELT distribution in the general male population. Materials and Methods: We compared the fitness of various well-known mathematical distributions with the IELT distribution of two previously published stopwatch studies of the Caucasian general male population and a stopwatch study of Dutch Caucasian men with lifelong premature ejaculation (PE. The accuracy of fitness is expressed by the Goodness of Fit (GOF. The smaller the GOF, the more accurate is the fitness. Results: The 3 IELT distributions are gamma distributions, but the IELT distribution of lifelong PE is another gamma distribution than the IELT distribution of men in the general male population. The Lognormal distribution of the gamma distributions most accurately fits the IELT distribution of 965 men in the general population, with a GOF of 0.057. The Gumbel Max distribution most accurately fits the IELT distribution of 110 men with lifelong PE with a GOF of 0.179. There are more men with lifelong PE ejaculating within 30 and 60 seconds than can be extrapolated from the probability density curve of the Lognormal IELT distribution of men in the general population. Conclusions: Men with lifelong PE have a distinct IELT distribution, e.g., a Gumbel Max IELT distribution, that can only be retrieved from the general male population Lognormal IELT distribution when thousands of men would participate in a IELT stopwatch study. The mathematical formula of the Lognormal IELT distribution is useful for epidemiological research of the IELT.

    This study aimed to examine gender differences in physician-certified sick leave and the extent to which these differences can be explained by work-related psychosocial and mechanical risk factors. Randomly drawn from the general population in Norway, the cohort comprised working men and women aged 18-69 years (N=12 255, response rate at baseline = 60.9%). Eligible respondents were interviewed in 2009 and registered with an active employee relationship of ≥ 100 actual working days in 2009 and 2010 (N=3688 men and 3070 women). The study measured 11 work-related psychosocial factors and 11 mechanical exposures, and outcomes of interest were physician-certified general sick leave (GSL) >0 days and long-term sick leave (LTSL) ≥ 40 working days during 2010. Women reported a significantly higher level of exposure to 9 of the 11 psychosocial factors evaluated. For mechanical factors, the reporting was mixed. After controlling for age, educational level, sick leave during 2009, housework, working hours and family status, a 1.7-fold risk for GSL and LTSL were found among women. In comparison with the initial model, adjusting for psychosocial factors reduced the excess risk by 21% and 27% for GSL and LTSL, respectively. The total effect of mechanical factors was negligible. Differences between occupations held by women and men explained an additional one-tenth of the excess risk for LTSL among women. Work-related psychosocial factors contributed significantly to a higher level of GSL and LTSL among women. The most important factors were demands for hiding emotions, emotional demands, and effort-payment imbalance.

    To investigate the diagnostic activity in general practice and the cumulative incidence of colorectal cancer (CRC) in individuals invited to the Danish national screening programme for CRC. A historical population-based cohort study. The Danish CRC screening programme and general practice. The 376,198 individuals invited to the Danish CRC screening programme from 1 March to 31 December 2014. The diagnostic activity (consultations and haemoglobin measures) in general practice in the year preceding the screening invitation and the cumulated incidence of CRC in the year following the screening invitation. Screening participants had significantly higher diagnostic activity than non-participants. Individuals with a positive faecal immunochemical test (FIT) had higher diagnostic activity compared to individuals with a negative FIT, and a small increase in the months leading up to the invitation. Individuals with a screen-detected CRC had lower diagnostic activity than individuals with no CRC. In total, 308 (25.3%) of CRCs diagnosed in the invited population were diagnosed outside the screening programme. Non-participants with CRC more often had low socio-economic status, high comorbidity and stage IV CRC than participants with CRC. There was a tendency that participants and those with a positive FIT had a higher diagnostic activity the year before the screening. This was not seen for those with CRC detected through screening. CRC must still be diagnosed in general practice in the invited population and non-participants are of special interest as they have higher risk of late stage CRC. Key Points Current awareness:Individuals with colorectal cancer (CRC) in screening may be symptomatic and CRC may still occur outside screening in the invited population. Most important points:The majority of individuals with CRC in screening cannot be expected to be diagnosed on symptomatic presentation in general practice GPs have to be aware that CRC still occurs outside screening in

    The main aim of this study is to describe the differences in the cardio-ankle vascular index (CAVI) in individuals with metabolic cardiovascular risk factors or a previous history of vascular diseases (WCVRF) compared to healthy individuals (free of risk factors and previous history of vascular diseases; FCVRF) in a general Mediterranean population. The secondary aim is to describe the proportion of CAVI≥9 depending on the cardiovascular risk category in both CVRF groups by sex. The study is a descriptive analysis of 2613 participants randomly selected in the Girona province (Catalonia, Spain). CAVI mean differences between sexes and age categories in both CVRF groups followed the same pattern, the FCVRF group (men 25.2%; women 14.4%) in turn had a lower prevalence of CAVI≥9 than the WCVRF group (men 57.9%; women 51.8%). The percentage of men and women with CAVI≥9 with low risk was 13.9% and 11.3% in the FCVRF group, and 31.8% and 42.0% in the WCVRF group; with moderate risk, it was 55.8% and 10.0% in the FCVRF group and 60.3% and 49.0% in the WCVRF group. In both sexes, FCVRF groups had a lower prevalence of CAVI≥9 as well as lower mean CAVI scores, across all 10 year-age categories from 40 to 69 years, than WCVRF groups. Moreover, CAVI≥9 was frequent in individuals with low and moderate coronary risk in the WCVRF group but also in the FCVRF group. These results suggest that CAVI assessment to detect asymptomatic arteriosclerosis could be a useful tool to improve cardiovascular risk stratification. Copyright © 2017 Elsevier B.V.

    Shoulder disorders in the occupational environment have been widely studied, but the quality of research and methodology applied vary. Little has been done to ascertain whether shoulder pain in female repetitive workers is due to any verifiable pathology, or to compare findings with the general population. Therefore, we decided to evaluate the prevalence of self-reported shoulder pain in a group of female supermarket cashiers and in the general female population using a standardized questionnaire. Shoulder pain prevalence was then compared to imaging findings in order to assess specific and non-specific pain prevalence. 196 cashiers and 302 controls filled in a standardized shoulder questionnaire and underwent an imaging examination of a shoulder. The prevalence of shoulder pain was significantly higher in the group of cashiers (46.4%) than in the general population (25.5%) (OR = 1.821; 95% CI: 1.426-2.325). Specific pain prevalence was higher among the controls (19.5%) than among the cashiers (13.2%). The more frequent reports of shoulder pain in the supermarket cashiers are not correlated with a higher prevalence of imaging abnormalities. The causes of these more frequent complaints should be probably sought in the psycho-social and occupational environment.

Using “constipation” and “China” as search terms; relevant papers were searched from January 1995 to April 2014. Data on prevalence, gender, diagnostic criteria, geographical area, educational class, age, race, and physician visit results were extracted and analyzed. Results. 36 trials were included. Prevalence rates of constipation in elderly population (18.1% and pediatric population (18.8% were significantly higher than that in general population (8.2%. Prevalence of constipation defined by non-Rome criteria was higher than that by Rome criteria in general population. Prevalence rates of constipation were different for different geographical area. People with less education were predisposed to constipation. In pediatric population, prevalence of constipation was the lowest in children aged 2–6 years. Prevalence of constipation in ethnic minorities was higher than that in Han people. People with constipation were predisposed to FD, haemorrhoid, and GERD. Only 22.2% patients seek medical advice in general population. Conclusions. In China, prevalence of constipation was lower compared with most of other countries. The factors including female gender, diagnostic criteria, geographical area, age, educational class, and race seemed to have major effects on prevalence of constipation.

    The Dissociative Disorders Interview Schedule was administered to a random sample of 502 adults in the general population of Winnipeg, a midwestern Canadian city. Results showed that paranormal/extrasensory experiences were common in the general population. They were linked to a history of childhood trauma and to other dissociative symptom clusters. A factor analysis of the paranormal experiences identified three factors which together accounted for 44.0% of the combined variance of the scores. A model is proposed in which paranormal experiences are conceptualized as an aspect of normal dissociation. Like dissociation in general, paranormal experiences can be triggered by trauma, especially childhood physical or sexual abuse. Such experiences discriminate individuals with childhood trauma histories from those without at high levels of significance.

    Full Text Available Abstract Background Smoking is a significant women's health issue. Examining smoking behaviors among occupational groups with a high prevalence of women may reveal the culture of smoking behavior and quit efforts of female smokers. The purpose of this study was to examine how smoking and quitting characteristics (i.e., ever and recent quit attempts among females in the occupation of nursing are similar or different to those of women in the general population. Methods Cross-sectional data from the Tobacco Use Supplement of the Current Population Survey 2006/2007 were used to compare smoking behaviors of nurses (n = 2, 566 to those of non-healthcare professional women (n = 93, 717. Smoking characteristics included years of smoking, number of cigarettes, and time to first cigarette with smoking within the first 30 minutes as an indicator of nicotine dependence. Logistic regression models using replicate weights were used to determine correlates of ever and previous 12 months quit attempts. Results Nurses had a lower smoking prevalence than other women (12.1% vs 16.6%, p p = 0.0002; but not in the previous 12 months (42% vs 43%, p = 0.77. Among those who ever made a quit attempt, nurses who smoked within 30 minutes of waking, were more likely to have made a quit attempt compared to other women (OR = 3.1, 95% CI: 1.9, 5.1. When considering quit attempts within the last 12 months, nurses whose first cigarette was after 30 minutes of waking were less likely to have made a quit attempt compared to other females (OR = 0.69, 95% CI: 0.49, 0.98. There were no other significant differences in ever/recent quitting. Conclusions Smoking prevalence among female nurses was lower than among women who were not in healthcare occupations, as expected. The lack of difference in recent quit efforts among female nurses as compared to other female smokers has not been previously reported. The link between lower level of nicotine dependence, as reflected by the longer

The objectives of the present study were to investigate individuals in the general population with hyperacusis regarding demographics, lifestyle, perceived general health and hearing ability, hyperacusis-specific characteristics and behavior, and comorbidity. Using data from a large-scale population-based questionnaire study, we investigated individuals with physician-diagnosed (n = 66 and self-reported (n = 313 hyperacusis in comparison to individuals without hyperacusis (n = 2995. High age, female sex, and high education were associated with hyperacusis, and that trying to avoid sound sources, being able to affect the sound environment, and having sough medical attention were common reactions and behaviors. Posttraumatic stress disorder, chronic fatigue syndrome, generalized anxiety disorder, depression, exhaustion, fibromyalgia, irritable bowel syndrome, migraine, hearing impairment, tinnitus, and back/joint/muscle disorders were comorbid with hyperacusis. The results provide ground for future study of these characteristic features being risk factors for development of hyperacusis and/or consequences of hyperacusis.

  4. Population cycles: generalities, exceptions and remaining mysteries

    2018-01-01

    Population cycles are one of nature's great mysteries. For almost a hundred years, innumerable studies have probed the causes of cyclic dynamics in snowshoe hares, voles and lemmings, forest Lepidoptera and grouse. Even though cyclic species have very different life histories, similarities in mechanisms related to their dynamics are apparent. In addition to high reproductive rates and density-related mortality from predators, pathogens or parasitoids, other characteristics include transgenerational reduced reproduction and dispersal with increasing-peak densities, and genetic similarity among populations. Experiments to stop cyclic dynamics and comparisons of cyclic and noncyclic populations provide some understanding but both reproduction and mortality must be considered. What determines variation in amplitude and periodicity of population outbreaks remains a mystery. PMID:29563267

  5. Factors associated with hepatitis C prevalence differ by the stage of liver fibrosis: A cross-sectional study in the general population in Poland, 2012-2016.

    Full Text Available There is a considerable burden of hepatitis C in Europe related to the lack of prompt diagnosis. We aimed to estimate the prevalence and related risk factors of HCV infections by the stages of liver fibrosis, using non-invasive methods, to understand testing needs in Poland.A cross-sectional study was conducted in 2012-2016 adopting a stratified random sampling of primary health care units followed by systematic sampling of patients within each unit. Study participants filled a questionnaire and donated blood for laboratory HCV testing. Additionally, the results of liver function tests and platelet count were collected to calculate APRI and FIB-4 scores. Cases were classified according to the level of fibrosis: 'significant fibrosis' (APRI≥0.7 or FIB4≥1.45 and 'no significant fibrosis' (APRI<0.7 and FIB4<1.45.Of 21 875 study participants, 102 were HCV-RNA positive. Prevalence of HCV infections and significant fibrosis was estimated at 0.47% (95% CI 0.38% - 0.57% and 0.12% (0.08% - 0.17%, respectively. Cases with significant fibrosis accounted for 51.6% (33.4%-69.9% in men and 34.4% (17.3%-51.4% in women. There was no correlation between the HCV prevalence and age. Blood transfusion prior to 1992 strongly predicted significant fibrosis as did the history of injecting drug use (IDU and ever having an HCV-infected sexual partner in men and caesarean sections in women. Factors associated with HCV infection without significant fibrosis were tattooing in men and younger age in women. We acknowledge limited possibility to study the associations between IDU and ever having HCV-infected sexual partner, given small sample sizes for these exposures.As no clear birth cohort affected by HCV could be identified, risk factor-based screening in the general population should be considered, taking into account the association between the increased risk of liver fibrosis and the history of transfusion prior to 1992 and caesarean sections.

    The Toronto-Alexithymia-Scale (TAS-20) is used worldwide as a valid measurement of alexithymia. Until now, population-based standardization and cut-off values of the German TAS-20 version have not been available. This study provides these by means of a representative German sample and by investigating the factorial structure of the TAS-20. Data were generated from a representative random sample of the German general population (1,859 subjects aged between 20 and 69). The TAS-20 sum score was normally distributed. The mean value was 49.5 (SD=9.3) in men and 48.2 (SD=9.2) in women. Divorce, single and low social status were associated with enhanced sum scores. Ten percent of the population exceeded the TAS-20 sum score threshold of >or=61. The 66th percentile reached 53 for men and 52 for women. Factor analysis identified three factors that match the scales of the English original version. An additional fourth factor ("importance of emotional introspection") was extracted. Total explanation of variance by these four factors was 52.27%. The sum score of the German TAS-20 version is suited for the standardized measure of alexithymia. For selecting alexithymic individuals in experimental studies, the cut-off >or=61 is possibly too restrictive. Therefore, we propose the 66th percentile for the identification of high alexithymics. The TAS-20 sum score is associated with important socio-demographic variables. The factorial structure is reliable; the fourth factor ("importance of emotional introspection") provides differentiation of content and allows for enhanced explanation of variance.

    (a) To identify clusters of eating patterns among the Italian population aged 15-64 years, focusing on typical Mediterranean diet (Med-diet) items consumption; (b) to examine the distribution of eating habits, as identified clusters, among age classes and genders; (c) evaluate the impact of: belonging to a specific eating cluster, level of physical activity (PA), sociocultural and psychological factors, as elements determining weight abnormalities. Data for this cross-sectional study were collected using self-reporting questionnaires administered to a sample of 33,127 subjects participating in the Italian population survey on alcohol and other drugs (IPSAD(®)2011). The cluster analysis was performed on a subsample (n = 5278 subjects) which provided information on eating habits, and adapted to identify categories of eating patterns. Stepwise multinomial regression analysis was performed to evaluate the associations between weight categories and eating clusters, adjusted for the following background variables: PA levels, sociocultural and psychological factors. Three clusters were identified: "Mediterranean-like", "Western-like" and "low fruit/vegetables". Frequent consumption of Med-diet patterns was more common among females and elderly. The relationship between overweight/obesity and male gender, educational level, PA, depression and eating disorders (p obesity. The low consumption of Med-diet patterns among youth, and the frequent association of sociocultural, psychological issues and inappropriate lifestyle with overweight/obesity, highlight the need for an interdisciplinary approach including market policies, to promote a wider awareness of the Mediterranean eating habit benefits in combination with an appropriate lifestyle.

    Are pre-medical students different than the other students in a General physics class? They often appear to be different, based on how often they seek help from the instructor or how nervous they are about 2 points on a lab report. But are these students different in a measurable characteristic? The purpose of this study is to better understand the characteristics of the students in the introductory physics classes. This is the first step toward improving the instruction. By better understanding the students the classroom, the organization and pedagogy can be adjusted to optimize student learning. The characteristics to be investigated during this study are: · student epistemological structure, · student attitudes, · science course preparation prior to this course, · study techniques used, · physics concepts gained during the class · performance in the class. The data will be analyzed to investigate differences between groups. The groups investigated will be major, gender, and traditional/nontraditional students.

    Multidetector computerized tomography (MDCT) appeared in the early 1990s, as a technological evolution of computerized tomography. As one would expect, the evolution continues and, each year, more powerful equipments appear, with new medical applications. However, the general use of this technique has lead to the dramatic increase on the general population irradiation. Special concern is required regarding the most vulnerable groups, like the pediatric population, the pregnant and the young female. Due to a larger awareness of this irradiation risks, some initiatives have been developed, coming from different areas, aiming to maximize the benefit to risk ratio of MDCT. (author)

    Variation in movement across time and space fundamentally shapes the abundance and distribution of populations. Although a variety of approaches model structured population dynamics, they are limited to specific types of spatially structured populations and lack a unifying framework. Here, we propose a unified network-based framework sufficiently novel in its flexibility to capture a wide variety of spatiotemporal processes including metapopulations and a range of migratory patterns. It can accommodate different kinds of age structures, forms of population growth, dispersal, nomadism and migration, and alternative life-history strategies. Our objective was to link three general elements common to all spatially structured populations (space, time and movement) under a single mathematical framework. To do this, we adopt a network modeling approach. The spatial structure of a population is represented by a weighted and directed network. Each node and each edge has a set of attributes which vary through time. The dynamics of our network-based population is modeled with discrete time steps. Using both theoretical and real-world examples, we show how common elements recur across species with disparate movement strategies and how they can be combined under a unified mathematical framework. We illustrate how metapopulations, various migratory patterns, and nomadism can be represented with this modeling approach. We also apply our network-based framework to four organisms spanning a wide range of life histories, movement patterns, and carrying capacities. General computer code to implement our framework is provided, which can be applied to almost any spatially structured population. This framework contributes to our theoretical understanding of population dynamics and has practical management applications, including understanding the impact of perturbations on population size, distribution, and movement patterns. By working within a common framework, there is less chance

    Full Text Available Abstract Background A recent study of adults aged ≥50 years reporting knee pain found an excess of radiographic knee osteoarthritis (knee ROA in symptomatic males compared to females. This was independent of age, BMI and other clinical signs and symptoms. Since this finding contradicts many previous studies, our objective was to explore four possible explanations for this gender difference: X-ray views, selection, occupation and non-articular conditions. Methods A community-based prospective study. 819 adults aged ≥50 years reporting knee pain in the previous 12 months were recruited by postal questionnaires to a research clinic involving plain radiography (weight-bearing posteroanterior semiflexed, supine skyline and lateral views, clinical interview and physical examination. Any knee ROA, ROA severity, tibiofemoral joint osteoarthritis (TJOA and patellofemoral joint osteoarthritis (PJOA were defined using all three radiographic views. Occupational class was derived from current or last job title. Proportions of each gender with symptomatic knee ROA were expressed as percentages, stratified by age; differences between genders were expressed as percentage differences with 95% confidence intervals. Results 745 symptomatic participants were eligible and had complete X-ray data. Males had a higher occurrence (77% of any knee ROA than females (61%. In 50–64 year olds, the excess in men was mild knee OA (particularly PJOA; in ≥65 year olds, the excess was both mild and moderate/severe knee OA (particularly combined TJOA/PJOA. This male excess persisted when using the posteroanterior view only (64% vs. 52%. The lowest level of participation in the clinic was symptomatic females aged 65+. Within each occupational class there were more males with symptomatic knee ROA than females. In those aged 50–64 years, non-articular conditions were equally common in both genders although, in those aged 65+, they occurred more frequently in symptomatic

    Full Text Available Abstract Background Hospitalizations for ambulatory care sensitive (ACS conditions are established indicators for the availability and quality of ambulatory care. We aimed to assess the differences between asylum-seeking children and children of the general population in a German city with respect to (i the prevalence of ACS hospitalizations, and (ii the utilization of emergency outpatient services for ACS conditions. Methods Using anonymous account data, all children admitted to the University Hospital Heidelberg in 2015 were included in our study. A unique cost unit distinguished asylum seekers residing in a nearby reception center (exposed from the children of the general population. We adapted international lists of ACS conditions and calculated the prevalence of ACS hospitalizations and the utilization of emergency outpatient services for ACS conditions, attributable fractions among the exposed (Afe and the population attributable fraction among total admissions (PAF for each outcome. Differences in the prevalence of each outcome between exposed and controls were analyzed in logistic regression models adjusted for sex, age group and quarterly admission. Results Of the 32,015 admissions in 2015, 19.9% (6287 were from inpatient and 80.1% (25,638 from outpatient care. In inpatient care, 9.8% (622 of all admissions were hospitalizations for ACS conditions. The Afe of ACS hospitalizations was 46.57%, the PAF was 1.12%. Emergency service use for ACS conditions could be identified in 8.3% (3088 of all admissions (Afe: 79.57%, PAF: 5.08%. The odds ratio (OR of asylum-seeking children being hospitalized for ACS conditions in comparison to the control group was 1.81 [95% confidence interval, CI: 1.02; 3.2]. The OR of the asylumseeking population compared to the general population for the utilization of emergency service use for ACS conditions was 4.93 [95% CI: 4.11; 5.91]. Conclusions Asylum-seeking children had significantly higher odds of ACS

    The influence of T-786C polymorphism in the promoter region of endothelial nitric oxide synthase (eNOS) on arteriosclerotic parameters by age and gender were examined. Brachial-ankle pulse wave velocity (baPWV), heart-rate adjusted augmentation index (AIx@75), pulse pressure (PP) and albumin-creatinine ratio (ACR) were assessed as arteriosclerotic parameters in addition to non-high-density lipoprotein cholesterol (non-HDL-C) to HDL-C (non-HDL-C/HDL-C) ratio in 1499 participants. T-786C polymorphism (rs2070744) was screened using a TaqMan allelic discrimination assay. Analyses of covariance were carried. Women with the non-C allele showed significantly lower AIx@75 in participants aged gender differences, possibly involving antioxidative and/or endothelial signaling other than inflammatory signaling.

  17. Are elderly dependency ratios associated with general population suicide rates?

    2011-05-01

    The elderly population size is increasing worldwide due to falling birth rates and increasing life expectancy. It has been hypothesized that as the elderly dependency ratio (the ratio of those over the age of 65 years to those under 65) increases, there will be fewer younger people available to care for older people and this, in turn, will increase the burden on younger carers with increased levels of psychiatric morbidity leading to an increase in general population suicide rates. A cross-national study examining the relationship between elderly dependency ratios and general population suicide rates was conducted using data from the World Health Organization and the United Nations websites. The main findings were of a significant and independent positive correlation between elderly dependency ratios and general population suicide rates in both genders. The contribution of cross-national differences in psychiatric morbidity in younger carers on general population suicide rates requires further study. The prevalence of psychiatric morbidity in younger carers of older people should be examined by: (i) cross-national studies using standardized measures of psychiatric morbidity that are education-free, culture-fair and language-fair; and (ii) within-country longitudinal studies with changing elderly dependency ratios over time.

    Full Text Available Background. The objectives of the study were to document knowledge, attitudes, and behaviors of women regarding cardiovascular diseases (CVDs and the determinants associated. Materials and Methods. The cross-sectional survey was conducted among a random sample of 830 women older than 18 years from the general population in Italy. Results. Almost all participants reported having heard about CVDs, and among them 89.4% and 74.7% identified smoking and high cholesterol level as risk factors. Only 26.5% identified the main CVDs risk factors. Women more knowledgeable were married and better educated and self-perceived a worse health status. Only 23% knew the main CVDs preventive measures and this knowledge was significantly higher in women who are unemployed, who are more educated, who have received information about CVDs from physicians, and who know the main risk factors. Respondents with lower education, those with at least three children, those who self-perceived a worse health status, and those who need information were most likely to have a positive attitude toward the perceived risk of developing CVDs. Women with two or three children or more were at high risk profiles 49% and 56% lower than women with one child. Conclusions. Educational programs are needed among women as support to improve knowledge and appropriate behavior about CVDs.

    Food-web dynamics arise from predator-prey, parasite-host, and herbivore-plant interactions. Models for such interactions include up to three consumer activity states (questing, attacking, consuming) and up to four resource response states (susceptible, exposed, ingested, resistant). Articulating these states into a general model allows for dissecting, comparing, and deriving consumer-resource models. We specify this general model for 11 generic consumer strategies that group mathematically into predators, parasites, and micropredators and then derive conditions for consumer success, including a universal saturating functional response. We further show how to use this framework to create simple models with a common mathematical lineage and transparent assumptions. Underlying assumptions, missing elements, and composite parameters are revealed when classic consumer-resource models are derived from the general model.

    The 7-item Generalized Anxiety Disorder Scale (GAD-7) is a practical self-report anxiety questionnaire that proved valid in primary care. However, the GAD-7 was not yet validated in the general population and thus far, normative data are not available. To investigate reliability, construct validity, and factorial validity of the GAD-7 in the general population and to generate normative data. Nationally representative face-to-face household survey conducted in Germany between May 5 and June 8, 2006. Five thousand thirty subjects (53.6% female) with a mean age (SD) of 48.4 (18.0) years. The survey questionnaire included the GAD-7, the 2-item depression module from the Patient Health Questionnaire (PHQ-2), the Rosenberg Self-Esteem Scale, and demographic characteristics. Confirmatory factor analyses substantiated the 1-dimensional structure of the GAD-7 and its factorial invariance for gender and age. Internal consistency was identical across all subgroups (alpha = 0.89). Intercorrelations with the PHQ-2 and the Rosenberg Self-Esteem Scale were r = 0.64 (P < 0.001) and r = -0.43 (P < 0.001), respectively. As expected, women had significantly higher mean (SD) GAD-7 anxiety scores compared with men [3.2 (3.5) vs. 2.7 (3.2); P < 0.001]. Normative data for the GAD-7 were generated for both genders and different age levels. Approximately 5% of subjects had GAD-7 scores of 10 or greater, and 1% had GAD-7 scores of 15 or greater. Evidence supports reliability and validity of the GAD-7 as a measure of anxiety in the general population. The normative data provided in this study can be used to compare a subject's GAD-7 score with those determined from a general population reference group.

    The Malaise Inventory is a commonly used self-completion scale for assessing psychiatric morbidity. There is some evidence that it may represent two separate psychological and somatic subscales rather than a single underlying factor of distress. This paper provides further information on the factor structure of the Inventory and on the reliability and validity of the total scale and two sub-scales. Two general population samples completed the full Inventory: over 11,000 subjects from the National Child Development Study at ages 23 and 33, and 544 mothers of adolescents included in the Isle of Wight epidemiological surveys. The internal consistency of the full 24-item scale and the 15-item psychological subscale were found to be acceptable, but the eight-item somatic sub-scale was less reliable. Factor analysis of all 24 items identified a first main general factor and a second more purely psychological factor. Receiver operating characteristic (ROC) analysis indicated that the validity of the scale held for men and women separately and for different socio-economic groups, by reference to external criteria covering current or recent psychiatric morbidity and service use, and that the psychological sub-scale had no greater validity than the full scale. This study did not support the separate scoring of a somatic sub-scale of the Malaise Inventory. Use of the 15-item psychological sub-scale can be justified on the grounds of reduced time and cost for completion, with little loss of reliability or validity, but this approach would not significantly enhance the properties of the Inventory by comparison with the full 24-item scale. Inclusion of somatic items may be more problematic when the full scale is used to compare particular sub-populations with different propensities for physical morbidity, such as different age groups, and in these circumstances it would be a sensible precaution to utilise the 15-item psychological sub-scale.

    Doctor -certified sick leave is prevalent in the health and social sector. We examined whether the higher risk of doctor-certified sick leave in women in health and social occupations compared to women in other occupations was explained by particular work-related psychosocial and mechanical risk factors. A randomly drawn cohort aged 18-69 years from the general population in Norway was surveyed in 2009 (n = 12,255, response at baseline = 60.9 %), and was followed up in the national registry of social transfer payments in 2010. Eligible respondents were women registered with an active employee relationship for ≥100 actual working days in 2009 and 2010 (n = 3032). Using this sample, we compared health and social workers (n = 661) with the general working population (n = 2371). The outcome of interest was long-term sick leave (LTSL) ≥21 working days during 2010. Eight psychosocial and eight mechanical factors were evaluated. After adjusting for age, previous LTSL, education and working hours/week, women in health and social occupations had a higher risk for LTSL compared with women in the general working population (OR = 1.42, 95 % CI = 1.13-1.79; p = 0.003). After adjusting for psychosocial and mechanical factors, 70 % of the excess risk for LTSL was explained compared with the initial model. The main contributory factors to the increased risk were threats of violence and violence, emotional demands and awkward lifting. Psychosocial and mechanical factors explained much of the excess risk for LTSL in women in health and social occupations compared with working women in general. Psychosocial risk factors were the most important contributors.

Methods A randomly drawn cohort aged 18–69 years from the general population in Norway was surveyed in 2009 (n = 12,255, response at baseline = 60.9 %, and was followed up in the national registry of social transfer payments in 2010. Eligible respondents were women registered with an active employee relationship for ≥100 actual working days in 2009 and 2010 (n = 3032. Using this sample, we compared health and social workers (n = 661 with the general working population (n = 2371. The outcome of interest was long-term sick leave (LTSL ≥21 working days during 2010. Eight psychosocial and eight mechanical factors were evaluated. Results After adjusting for age, previous LTSL, education and working hours/week, women in health and social occupations had a higher risk for LTSL compared with women in the general working population (OR = 1.42, 95 % CI = 1.13–1.79; p = 0.003. After adjusting for psychosocial and mechanical factors, 70 % of the excess risk for LTSL was explained compared with the initial model. The main contributory factors to the increased risk were threats of violence and violence, emotional demands and awkward lifting. Conclusions Psychosocial and mechanical factors explained much of the excess risk for LTSL in women in health and social occupations compared with working women in general. Psychosocial risk factors were the most important contributors.

    Full Text Available Background: Benzodiazepines can be classified as one of the most frequently prescribed categories of medication. This medication category is distinguished by a high risk of tolerance and dependence, in the case of long-term, excessive use. Aim: The aim of our study was to analyse the use of benzodiazepines in the general population, municipality of Berane, Montenegro, during the previous year. Methods: Research was based on the analysis of 1000 prescriptions of benzodiazepines, issued by physicians in Primary Health Care. The diagnostic manual utilised for the purpose of this research was International Classification of Diseases (ICD-10. The survey was conducted for a period of 40 days during January and February 2015. Results: The study was performed in the general population, age from 18 to 98 years (621 females and 379 males. The average age of all participants in the study was 64.1±13.1 years. Analysis of data confirmed that the most frequently prescribed from the group of benzodiazepines were: diazepam (42.2%, bromazepam (30.3%, lorazepam (16.4%, alprazolam (6.4%, nitrazepam (2.6% and clonazepam (2.1%. The significant statistical difference (x2=58.664; p<0.001 was found between female patients who used benzodiazepines in 62.1% of cases, compared to male patients who used benzodiazepines in 37.9% of cases. It was confirmed that benzodiazepines were usually prescribed for 17 different diagnoses, mostly for diagnoses from the group I, viz. cluster-diseases of the circulatory system (39.7%, group F-mental and behavioural disorders (31.1% and group E-endocrine, nutritional and metabolic diseases (7.7%. Conclusion: Studies about drug utilisation provide plenty of useful information which can be further used with the aim of achieving more rational prescribing and more effective patient treating.

    Child maltreatment and its consequences are considered a major public health problem. So far, there is only one study from Germany reporting prevalence rates on different types of maltreatment. A representative sample of the German general population was examined for experiences of child maltreatment using the Childhood Trauma Questionnaire (CTQ) between September and November 2016. A total of 2510 (53.3% female) participants between 14 and 94 years (M = 48.8 years) were enrolled. Besides the CTQ, a range of sociodemographic information was collected. The interrelatedness of different types of maltreatment was examined using configuration analysis and predictors for maltreatment were identified by performing binary logistic regression analyses. Overall, 2.6% (f: 3.9%, m: 1.2%) of all participants reported severe emotional abuse, 3.3% (f: 3.4%, m: 3.3%) severe physical abuse, 2.3% (f: 3.7%, m: 0.7%) severe sexual abuse, 7.1% (f: 8.1%, m: 5.9%) severe emotional neglect and 9% (f: 9.2%, m: 8.9%) severe physical neglect. Women were more likely to report at least moderate sexual and emotional abuse than men. The largest difference between age groups was reported for physical neglect, with participants aged over 70 years reporting the highest rates. Participants who reported childhood maltreatment were more likely to be unemployed or have lower educational outcomes. The most common combination of maltreatment types were physical and emotional neglect, all five types of maltreatment combined and physical and emotional neglect and physical abuse combined. Child maltreatment, especially physical neglect is common in the German population. Women seem to be at greater risk for sexual and emotional abuse than men. Knowledge about different types of maltreatment based on the Childhood Trauma Questionnaire (CTQ) can help to put findings of future studies into an epidemiological and societal context.

    Both normal aging and neurodegenerative diseases such as Alzheimer's disease cause morphological changes of the brain. To better distinguish between normal and abnormal cases, it is necessary to model changes in brain morphology owing to normal aging. To this end, we developed a method for analyzing and visualizing these changes for the entire brain morphology distribution in the general aging population. The method is applied to 1000 subjects from a large population imaging study in the elderly, from which 900 were used to train the model and 100 were used for testing. The results of the 100 test subjects show that the model generalizes to subjects outside the model population. Smooth percentile curves showing the brain morphology changes as a function of age and spatiotemporal atlases derived from the model population are publicly available via an interactive web application at agingbrain.bigr.nl.

    The purposes of this study were to compare the working situation of cancer survivors and the general (cancer-free) population and investigate characteristics associated with the increased likelihood of unemployment between the two groups. We selected 1927 cancer survivors from the 2008 Korean Community Health Survey data less than 65 years of age and used propensity score matching to randomly select 1924 individuals from the general population who closely resembled the cancer survivors. Compared to the general population, cancer survivors were less likely to be engaged in paid work, particularly as permanent workers, and were more likely to work regular hours. Additionally, they tended to do less work that involved lifting or moving heavy objects and uncomfortable postures and were more willing to express their emotions. An increased probability of unemployment among cancer survivors was associated with being over 50 years old, being female, having a lower monthly income, having multiple comorbidities, belonging to a nuclear family, being a National Basic Livelihood Act beneficiary, and having a recent diagnosis. Cancer survivors may want to pursue flexible occupations and improve their working situation. Further, they perceive their workplace more positively compared to the general population. Respecting the cancer survivor's choice to find flexible working conditions that suit their health needs and status, health-care providers involved in managing work-related issues among cancer survivors should be aware of the interaction between work-related concerns and post-cancer disease management.

    Full Text Available Background: Hepatitis C virus is encountered sporadically in Bangladesh. It results in a wide range liver diseases, with asymptomatic acute hepatitis rarely at one end to HCC at the other end of the spectrum. Methods: 1018 individuals of different age groups and sex with varied religious, educational and social backgrounds were tested for anti-HCV by ELISA. Before testing, blood samples were preserved at -20°C. The study was conducted in a semi-urban location on the outskirts of Dhaka. Results: 0.88% tested positive for anti HCV. None of them tested positive for HBsAg. There was a male predominance and those who tested positive were mostly between 17 and 50 years of age. Major risk factors for exposure to HBV appeared to be injudicious use of injectable medications, treatment by unqualified, traditional practitioners, mass-vaccination against cholera and smallpox, barbers and body piercing. Conclusion: HCV remains an important cause of morbidity and mortality in Bangladesh. Key words: HCV; prevalence; general population; Bangladesh.DOI: 10.3329/bsmmuj.v2i1.3705 BSMMU J 2009; 2(1: 14-17

    There is evidence that experimentally elicited auditory illusions in the general population index risk for psychotic symptoms. As little is known about underlying cortical mechanisms of auditory illusions, an experiment was conducted to analyze processing of auditory illusions in a general population sample. In a follow-up design with two measurement moments (baseline and 6 months), participants (n = 83) underwent the White Noise task under simultaneous recording with a 14-lead EEG. An auditory illusion was defined as hearing any speech in a sound fragment containing white noise. A total number of 256 speech illusions (SI) were observed over the two measurements, with a high degree of stability of SI over time. There were 7 main effects of speech illusion on the EEG alpha band-the most significant indicating a decrease in activity at T3 (t = -4.05). Other EEG frequency bands (slow beta, fast beta, gamma, delta, theta) showed no significant associations with SI. SIs are characterized by reduced alpha activity in non-clinical populations. Given the association of SIs with psychosis, follow-up research is required to examine the possibility of reduced alpha activity mediating SIs in high risk and symptomatic populations.

    Pertussis continues to be an important cause of morbidity and mortality in children too young to be fully protected despite high vaccination coverage. This has been attributed to waning immunity in older people, leading to the development of strategies to increase levels of immunity. A systematic review was conducted to assess the clinical and cost effectiveness of four population-based strategies for pertussis booster vaccination: single booster at 12-24 months old, single pre-school booster, single adolescent booster and multiple boosters in adulthood every 10 years. Electronic databases and Internet resources were searched to June 2006. Nine observational studies, four mathematical models and eight economic evaluations were included, evaluating four different strategies. Strong evidence to recommend any of these strategies was not found.

    This study aimed to investigate views on life and death among physicians, nurses, cancer patients, and the general population in Japan and examine factors affecting these views. We targeted 3,140 physicians, 470 nurses, 450 cancer patients, and 3,000 individuals from the general population. We used the Death Attitudes Inventory (DAI) to measure attitudes toward life and death. The collection rates were 35% (1,093/3,140), 78% (366/470), 69% (310/450), and 39% (1,180/3,000) for physicians, nurses, patients, and the general population, respectively. We found that age, sex, social role (i.e., physician, nurse, cancer patient, and general population) were significantly correlated with DAI subscales. Compared with general population, attitudes toward death of physicians, nurses and cancer patients differed significantly even after adjusted their age and sex. Our study is the first to analyze differences in views on life and death among physicians, nurses, cancer patients, and the general population in Japan.

    CONDIMENT is a code for the computation of ion migration and diffusion in areas close to radwaste storage facilities. This type of application was found to require a mesh pattern and boundary conditions different from the usual, which justifies the writing of a new code. A first version (version 2) only convers the migration of a single, non radioactive ion. The discretization, the selection of an implicit scheme, and the various boundary conditions are described. Physical quantities such as diffusion coefficient, porosity, retardation factor and permeability vary in space but not in time. A first extension consists of taking consideration radioactivity and filiation. Discretization with respect to time is modified, and a check performed on the original analytical solutions. In a second extension, consideration is given to non-linear adsorption, which makes it necessary to use the NEWTON-RAPHSON method. One can thus modelize the FREUNDLICH isotherms, in spite of the singular point at the origin. Diffusion, apparent porosity and permeability values can be changed as computed proceeds. The last extension is the introduction of two ions with the formation of precipitate. The formulation is derived from that used for non-linear adsorption, the precipitate playing a part similar to that of adsorbed concentration. Agreement with the original analytical solutions is verified. The case of migration with several interacting ions is approached from the theoretical standpoint. We described the discretization, which is similar to that in the first version, but involves many additional variables. Numerical stability is shown to be unconditional [fr

  7. Border Collision Bifurcations in a Generalized Model of Population Dynamics

    2016-01-01

    Full Text Available We analyze the dynamics of a generalized discrete time population model of a two-stage species with recruitment and capture. This generalization, which is inspired by other approaches and real data that one can find in literature, consists in considering no restriction for the value of the two key parameters appearing in the model, that is, the natural death rate and the mortality rate due to fishing activity. In the more general case the feasibility of the system has been preserved by posing opportune formulas for the piecewise map defining the model. The resulting two-dimensional nonlinear map is not smooth, though continuous, as its definition changes as any border is crossed in the phase plane. Hence, techniques from the mathematical theory of piecewise smooth dynamical systems must be applied to show that, due to the existence of borders, abrupt changes in the dynamic behavior of population sizes and multistability emerge. The main novelty of the present contribution with respect to the previous ones is that, while using real data, richer dynamics are produced, such as fluctuations and multistability. Such new evidences are of great interest in biology since new strategies to preserve the survival of the species can be suggested.

    Radiation protection training for the general employee at the Oak Ridge National Laboratory has undergone a great deal of restructuring in the last two years. The number of personnel totally dedicated to nuclear facilities is less than a fifth of our employees and the percentage of contracted employees who are dedicated radiation workers is much smaller. However, the aging of our facilities and increasing emphasis on environmental control means that everyone needs to understand the basics of radiation protection. In accordance with changing DOE guidelines and internal ORNL policies, greater emphasis has been placed on keeping training focused on current issues, training the total workforce, and requiring some type of testing or feedback mechanism. This report describes efforts to instill respect, but not fear, of radiation in the work environment. Flexible tools are being developed to meet this objective for several diverse general employee populations. Continuing efforts include consideration of computer-based training for retraining, developing additional modules for specialized groups and jobs, and testing/documentation appropriate to each population segment. 6 refs

    Increasing evidence suggests that aldosterone promotes renal damage. Since data on the association between aldosterone and renal function in the general population are sparse, we chose to address this issue. We investigated the associations between the plasma aldosterone concentration (PAC) or the aldosterone-to-renin ratio (ARR) and the estimated glomerular filtration rate (eGFR) in a sample of adult men and women from Northeast Germany. A study population of 1921 adult men and women who participated in the first follow-up of the Study of Health in Pomerania was selected. None of the subjects used drugs that alter PAC or ARR. The eGFR was calculated according to the four-variable Modification of Diet in Renal Disease formula. Chronic kidney disease (CKD) was defined as an eGFR < 60 ml/min/1.73 m2. Linear regression models, adjusted for sex, age, waist circumference, diabetes mellitus, smoking status, systolic and diastolic blood pressures, serum triglyceride concentrations and time of blood sampling revealed inverse associations of PAC or ARR with eGFR (ß-coefficient for log-transformed PAC -3.12, p < 0.001; ß-coefficient for log-transformed ARR -3.36, p < 0.001). Logistic regression models revealed increased odds for CKD with increasing PAC (odds ratio for a one standard deviation increase in PAC: 1.35, 95% confidence interval: 1.06-1.71). There was no statistically significant association between ARR and CKD. Our study demonstrates that PAC and ARR are inversely associated with the glomerular filtration rate in the general population.

    Full Text Available ABSTRACT Objective: To estimate the degree of tobacco addiction and identify independently associated factors by comparing the psychiatric population of secondary and tertiary care with the general population of the primary healthcare network. Method: This is a cross-sectional epidemiological study, conducted in a municipality of São Paulo, with 134 smokers of a Mental Health Outpatient Unit (MHOU, a Psychiatric Hospital (PH, and a Primary Healthcare Unit (PHU. Data were collected by means of individual interviews, recorded on a mobile device. Data were statistically processed using Stata/12 Results: Of the 134 participants, 54.5% were women. While 49.1% of the psychiatric population (MHOU/PH had medium/high nicotine addiction, 58.3% of smokers of the general population had very low/low dependency. The Poisson regression model indicated a higher prevalence of smokers with high dependence among men (PR = 1.41, people aged 49 years or less (15 - 29 years, PR = 4.06, 30 - 39 PR = 2.96 years, 40 - 49 years PR = 1.84, with severe mental disorders (PR = 3.05, with anxiety disorders/other (PR = 3.98, and with high suicide risk (PR = 1.55. Conclusion: Nicotine dependence was greater in the psychiatric population than in the general population. The independent factors associated with severe dependence were sex, age group, diagnosis, and current risk of suicide. These results trigger reflection among nurses on the need to focus more attention on a neglected subject in mental health services.

    Mammography is the only method presently considered appropriate for mass screening of breast cancer. However, higher breast density was strongly associated with lower mammographic sensitivity. Breast density is also identified as independent and strongest risk factors for breast cancer. Studies have shown women with high breast density have four to six times increased risk of breast cancer as compare to women with fatty breast. It varies between different age group it generally decreases with increasing age in postmenopausal women and it can be different in different ethnic groups and people from different geographical areas. This study evaluates the breast density in Indian population and its relationship with the age. We reviewed of all screening mammography examinations performed from May 2012 to January 2015 at our institute PGIMER, Chandigarh, INDIA. Descriptive analyses were used to examine the association between age and breast density. A total of 6132 screening mammograms were performed. Each subgroup categorized by decade of age. There was a significant inverse relationship between age and breast density (P density in Indian and Western population with more Indians having ACR Grade 1 and 2 and Western population having 2 and 3. We found an inverse relationship between patient age and mammographic breast density. However, there were a large proportion of young women who had lower grades of mammographic density which could potentially benefit from the use of routine screening mammography in this subgroup of patients. Moreover, the breast density of Indian population is less when compared to the Western population. This might suggest that mammography is a good modality of choice for screening Indian population. © 2017 Wiley Periodicals, Inc.

    To assess the levels of polycyclic aromatic hydrocarbons monohydroxy metabolites in urine of general population in China among 8 provinces, provide the baseline of the metabolites in the general population. From 2009 to 2010, 18 120 subjects of general population aged 6-60 years old were recruited from 24 areas among 8 provinces in east, west and central areas of China mainland by cluster random sampling. The information of the living environment and health condition were collected by questionnaire and spot urine samples were collected, 4 680 urine samples were analysed by high performance liquid chromatography with tandem mass spectrometry, and monohydroxy metabolites distribution in urine among groups of gender and ages were analysed. Geometric means (GM) of 2-naphthol, 1-naphthol, 3-phenanthrol and 1-hydroxypyrene concentration in urine (95%CI) were 1.85 (1.75-1.95), 1.55 (1.50-1.61), 0.57 (0.54-0.59) and 0.82 (0.78-0.85) µg/L, respectively;and median are 2.44, population were significantly different (P population aged 6-12, 13-16, 17-20, 21-30, 31-45 and 46-60 years old were 1.60, 1.56, 1.69, 2.23, 1.91 and 1.86 µg/L (χ(2) = 17.90, P population were different, it provided a basic data for the further study of polycyclic aromatic hydrocarbons biomonitoring in the population.

    Previous epidemiological research indicates that police officers have an elevated risk of death relative to the general population overall and for several specific causes. Despite the increased risk for mortality found in previous research, controversy still exists over the life expectancy of police officers. The goal of the present study was to compare life expectancy of male police officers from Buffalo New York with the U.S. general male population utilizing an abridged life table method. On average, the life expectancy of Buffalo police officers in our sample was significantly lower than the U.S. population (mean difference in life expectancy =21.9 years; 95% CI: 14.5-29.3; ppolice officers was shorter and differences were more pronounced in younger age categories. Additionally, police officers had a significantly higher average probability of death than did males in the general population (mean difference= 0.40; 95% CI: 0.26,-0.54; ppolice officers was 21 times larger than that of the general population (Buffalo male officers vs. U.S. males = 21.7, 95% CI: 5.8-37.7). Possible reasons for shorter life expectancy among police are discussed, including stress, shift work, obesity, and hazardous environmental work exposures. PMID:24707585

    Theory of Mind (ToM) is the ability to assign a set of mental states to yourself and others. In bipolar disorders, alteration of social relationship can be explained by the impairment of the functioning of ToM. Deficit in ToM could be a trait marker of bipolar disorder and people in the general population with high hypomanic personality scores would be more likely to develop bipolar disorders. This study examined 298 participants. Measures of hypomanic personality were evaluated using the Hypomanic Personality Scale. ToM was explored using the Yoni task. Participants also completed the BDI-II. Forward multiple regressions were performed to examine the effect of components of the HPS on the total score in the ToM task. In the women's group, no subscales of the HPS were included in the model. Conversely, the analyses performed on men revealed that the mood vitality and excitement subscale was a significant predictor of ToM abilities. Our study is the first to show the impact of certain dimensions of hypomanic personality on performance in ToM in a male sample. This result supports the idea that deficits in ToM can be a trait marker of bipolar disorder in a healthy male population. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Abstract Background General practice based registration networks (GPRNs provide information on morbidity rates in the population. Morbidity rate estimates from different GPRNs, however, reveal considerable, unexplained differences. We studied the range and variation in morbidity estimates, as well as the extent to which the differences in morbidity rates between general practices and networks change if socio-demographic characteristics of the listed patient populations are taken into account. Methods The variation in incidence and prevalence rates of thirteen diseases among six Dutch GPRNs and the influence of age, gender, socio economic status (SES, urbanization level, and ethnicity are analyzed using multilevel logistic regression analysis. Results are expressed in median odds ratios (MOR. Results We observed large differences in morbidity rate estimates both on the level of general practices as on the level of networks. The differences in SES, urbanization level and ethnicity distribution among the networks' practice populations are substantial. The variation in morbidity rate estimates among networks did not decrease after adjusting for these socio-demographic characteristics. Conclusion Socio-demographic characteristics of populations do not explain the differences in morbidity estimations among GPRNs.

    To compare aesthetic perception of smile between general population and dentists by varying lengths of maxillary lateral incisors. Introduction: Patient perception and expectation of their smile plays a very important role when providing an anterior tooth restoration. The aim of conducting the study was to compare the perception of esthetic smile between general population and dentists by varying length of maxillary lateral incisors. Design: Cross sectional study. Materials and Methods: A photograph of a female smile from frontal view was digitally altered to produce images with varying lengths of maxillary lateral incisor. These images were arranged in descending order; from most attractive to least attractive by the participants. The participants of the study included two groups; first group comprised of Dental Surgeons where as second group consisted of general population. Results: Evaluation of the results showed a significant difference in aesthetic perception of smile between the Dentist and general population. Conclusion: Perception of aesthetics is not similar between the dentists and the general population. (author)

    The primary objective of this study was to quantify the differences in the prevalence rate and costs of hospital medical errors between the general population and an elderly population aged ≥65 years. Methods from an actuarial study of medical errors were modified to identify medical errors in the Premier Hospital Database using data from 2009. Visits with more than four medical errors were removed from the population to avoid over-estimation of cost. Prevalence rates were calculated based on the total number of inpatient visits. There were 3,466,596 total inpatient visits in 2009. Of these, 1,230,836 (36%) occurred in people aged ≥ 65. The prevalence rate was 49 medical errors per 1000 inpatient visits in the general cohort and 79 medical errors per 1000 inpatient visits for the elderly cohort. The top 10 medical errors accounted for more than 80% of the total in the general cohort and the 65+ cohort. The most costly medical error for the general population was postoperative infection ($569,287,000). Pressure ulcers were most costly ($347,166,257) in the elderly population. This study was conducted with a hospital administrative database, and assumptions were necessary to identify medical errors in the database. Further, there was no method to identify errors of omission or misdiagnoses within the database. This study indicates that prevalence of hospital medical errors for the elderly is greater than the general population and the associated cost of medical errors in the elderly population is quite substantial. Hospitals which further focus their attention on medical errors in the elderly population may see a significant reduction in costs due to medical errors as a disproportionate percentage of medical errors occur in this age group.

    Full Text Available Abstract Background During the colonization of the world, after dispersal out of African, modern humans encountered changeable environments and substantial phenotypic variations that involve diverse behaviors, lifestyles and cultures, were generated among the different modern human populations. Results Here, we study the level of population differentiation among different populations of human genes. Intriguingly, genes involved in osteoblast development were identified as being enriched with higher FST SNPs, a result consistent with the proposed role of the skeletal system in accounting for variation among human populations. Genes involved in the development of hair follicles, where hair is produced, were also found to have higher levels of population differentiation, consistent with hair morphology being a distinctive trait among human populations. Other genes that showed higher levels of population differentiation include those involved in pigmentation, spermatid, nervous system and organ development, and some metabolic pathways, but few involved with the immune system. Disease-related genes demonstrate excessive SNPs with lower levels of population differentiation, probably due to purifying selection. Surprisingly, we find that Mendelian-disease genes appear to have a significant excessive of SNPs with high levels of population differentiation, possibly because the incidence and susceptibility of these diseases show differences among populations. As expected, microRNA regulated genes show lower levels of population differentiation due to purifying selection. Conclusion Our analysis demonstrates different level of population differentiation among human populations for different gene groups.

    Determining the differences in the perception of risks between experts who are regularly exposed to radiation, and lay people provides important insights into how potential hazards may be effectively communicated to the public. In the present study we examined lay people's (N = 1020) and experts' (N = 332) perception of five different radiological risks: nuclear waste, medical x-rays, natural radiation, an accident at a nuclear installation in general, and the Fukushima accident in particular. In order to link risk perception with risk communication, media reporting about radiation risks is analysed using quantitative and qualitative content analyses. The results showed that experts perceive radiological risks differently from the general public. Experts' perception of medical X-rays and natural radiation is significantly higher than in general population, while for nuclear waste and an accident at a nuclear installation, experts have lower risk perception than the general population. In-depth research is conducted for a group of workers that received an effective dose higher than 0.5 mSv in the year before the study; for this group we identify predictors of risk perception. The results clearly show that mass media don't use the same language as technical experts in addressing radiological risks. The study demonstrates that the discrepancy in risk perception and the communication gap between the experts and the general population presents a big challenge in understanding each other

    The objective of this study was to investigate napping habits and their associated factors in the Japanese adult general population. The cross-sectional survey was conducted in November 2007 for subjects selected randomly from among 300 districts throughout Japan. Data from 7664 people (3527 men and 4137 women), aged 20-99 years, were analyzed. Participants completed a self-administered questionnaire on frequency and duration of napping. The percentage of responders for high-frequency napping, four or more days per week, was 21.2% among men and 17.1% among women. The percentage of responders for long-duration napping, 2 h or more per one nap, was 2.9% among men and 2.6% among women. Multivariate logistic regression analyses revealed that men, older age, smoking, insomnia symptoms, long sleep duration, excessive daytime sleepiness, and having sufficient rest obtained by sleep were positively associated with high-frequency napping, whereas alcohol drinking showed a negative association. Older age was negatively associated with long-duration napping whereas living in a large community, smoking, long sleep duration, excessive daytime sleepiness, and psychological stress showed a positive association. These findings provide important data for future studies aimed at improvement of sleep habits. Copyright © 2016 Elsevier B.V. All rights reserved.

    Based on the International Classification of Functioning, Disability, and Health (ICF) and the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), The Functioning Disability Evaluation Scale-Adult version (FUNDES-Adult) began development in 2011. The FUNDES-Adult was designed to assess the difficulty level of an individual's activities and participation in daily life. There is a lack of research regarding the profile of activity and participation for the general adult population. The purposes of this study were to establish activity and participation norms for the general adult population in Taiwan and to describe, discuss, and compare the activity and participation profile with other population. A population-based survey was administered in 2013 using a computer-assisted telephone interviewing system (CATI system). Using probability proportional to size (PPS) sampling and systematic sampling with random digit dialing (RDD), 1500 adults from Taiwan's general population were selected to participate in the survey. The FUNDES-Adult with six domains and two dimensions (performance and capability) was used to obtain data on activities and participation levels. A higher domain score indicated higher participation restriction. Approximately 50% of the respondents were male, and the average age of the respondents was 45.23 years. There were no significant differences in the demographic features between the sample and the population. Among the six domains, the self-care domain score was the lowest (least restriction) and the participation domain score was the highest (most restriction). Approximately 90% of the sample scored were less than 15, and only 0.1% scored more than 80. This is the first cross-national population-based survey to assess norms of activity and participation relevant to the general population of Taiwan. As such, the results of this survey can be used as a reference for comparing the activity and participation (AP) functioning of

    This research was undertaken to examine the role between cumulative exposure to different types of traumatic events and posttraumatic stress disorder (PTSD) status in general population and prison samples. Two archival datasets were examined: the standardization sample for the Detailed Assessment of Posttraumatic States (DAPS; Briere, 2001), and data from a study on trauma and posttraumatic sequelae among inmates and others. PTSD was found in 4% of the general population sample and 48% of the prison sample. Trauma exposure was very common among prisoners, including a 70% rate of childhood sexual abuse for women and a 50% rate for men. Lifetime number of different types of trauma was associated with PTSD in both the general population and prison samples, even when controlling for the effects of sexual trauma. Cumulative interpersonal trauma predicted PTSD, whereas cumulative noninterpersonal trauma did not. In the general population sample, participants who had only 1 type of trauma exposure had a 0% likelihood of current PTSD, whereas those with 6 or more other trauma types had a 12% likelihood. In the prison sample, those with only 1 type of trauma exposure had a 17% percent likelihood of current PTSD, whereas those exposed to 6 or more other trauma types had a 64% chance of PTSD. Cumulative trauma predicts current PTSD in both general population and prison samples, even after controlling for sexual trauma. PTSD appears to develop generally as a function of exposure to multiple types of interpersonal trauma, as opposed to a single traumatic event.

    2004-01-01

    Insomnia is a frequent symptom in the general population; numerous studies have proven this. In the past years, classifications have gradually given more emphasis to daytime repercussions of insomnia and to their consequences on social and cognitive functioning. They are now integrated in the definition of insomnia and are used to quantify its severity. If the daytime consequences of insomnia are well known at the clinical level, there are few epidemiological data on this matter. The aim of this study was to assess the daytime repercussions of insomnia complaints in the general population of France. A representative sample (n=5,622) aged 15 or older was surveyed by telephone with the help of the sleep-EVAL expert system, a computer program specially designed to evaluate sleep disorders and to manage epidemiological investigations. Interviews have been completed for 80.8% of the solicited subjects (n=5,622). The variables considered comprised insomnia and its daytime repercussions on cognitive functioning, affective tone, daytime sleepiness and diurnal fatigue. Insomnia was found in 18.6% of the sample. The prevalence was higher in women (22.4%) than in men (14.5%, psleep. Nearly 75% of insomnia complainers reported having a disrupted sleep or waking up too early in the morning and about 40% said they had a non-restorative sleep. Repercussions on daytime functioning were reported by most insomnia subjects (67%). Repercussions on cognitive functioning changed according age, number of insomnia symptoms and the use of a psychotropic medication. A decreased efficiency was more likely to be reported by subjects between 15 and 44 years of age (OR: 2.9), those using a psychotropic (OR: 1.5), those reporting at least three insomnia symptoms (OR: 1.4) and women (OR: 1.4). The highest probability of the appearance of concentration difficulties was found in subjects younger than 65 Years, having a depressive disorder and using a psychotropic (15-44 years: OR 19.1; 45-64 years

    Vasopressin plays an important role in maintaining volume homeostasis. However, recent studies suggest that vasopressin also may play a detrimental role in the progression of chronic kidney disease. It therefore is of interest to identify factors that influence vasopressin concentration, particularly modifiable ones. Cross-sectional analyses. Data used are from participants in a large general-population cohort study (Prevention of Renal and Vascular Endstage Disease [PREVEND]). Patients with a missing copeptin value (n=888), nonfasting blood sample (n=495), missing or assumed incorrect 24-hour urine collection (n=388), or heart failure (n=20) were excluded, leaving 6,801 participants for analysis. Identification of lifestyle- and diet-related factors that are associated with copeptin concentration. Copeptin concentration as surrogate for vasopressin. Copeptin was measured by an immunoluminometric assay as a surrogate for vasopressin. Associations were assessed in uni- and multivariable linear regression analyses. Median copeptin concentration was 4.7 (IQR, 2.9-7.6) pmol/L. When copeptin was studied as a dependent variable, the final stepwise backward model revealed associations with higher copeptin concentrations for lower 24-hour urine volume (P firm conclusions on cause-effect relationships. Important lifestyle- and diet-related factors associated with copeptin concentration are current smoking, alcohol use, protein and potassium intake, and particularly fluid and sodium intake. These data form a rationale to investigate whether intervening on these factors results in a lower vasopressin concentration with concomitant beneficial renal effects.

    This paper aimed to compare the profile of mortality from external causes among Seventh-day Adventists and the general population of Espírito Santo from 2003 to 2009. A search of Adventists was performed in the nominal database of the Mortality Information System containing data on Adventists provided by the administrative offices of the institution. Deaths from external causes occurred during the study period were then divided into two groups: Adventists and the general population. Adventists had lower proportional mortality from external causes (10%) than the general population (19%), and males were the main reason for this difference. In both groups, deaths prevailed in the 20-29 years age group. Deaths from accidental causes were most significant among Adventists (68.08%), while deaths from intentional causes related to assault and self-inflicted injuries were more significant in the general population (53.67% of all deaths). The standardized mortality ratio for external causes was 41.3, thus, being Adventist reduced mortality by 58.7%. It is believed that the benefit of Adventists observed for mortality from external causes is related to this group's abstinence from alcohol consumption.

    To collect mothers' reports of the range of behaviours used by them in the management of their children's difficult behaviour. A cross-sectional study using an interview with both semi-structured and open-ended question routes. SAMPLING FRAME: The population of mothers with 10-year-old children living in the New Forest region of Hampshire, UK. Mothers (n=67), selected from the sampling frame, were interviewed about the range of parenting behaviours they used in the management of their children's difficult behaviour. Mothers reported a wide range of behaviours. Both authoritative (e.g. reasoning was mentioned by 42%) and authoritarian (e.g. the use of physical punishment was mentioned by 37%) behaviours were mentioned frequently. Although the different behaviours within these domains were intercorrelated, there was little overlap between the two domains. The use of praise for good behaviour seemed to be independent of other behaviours. There was no association between mothers' parenting behaviours and the behaviour problems of their children. These data suggest that parenting takes many forms, with variations of behaviour across the 'normal' range being unlikely to represent a significant risk to children's development. Public funding for parenting education should be targeted at those children who are at significant risk from extreme forms of parenting.

    The aim of this study was to examine the prevalence and typologies of controlling behaviors within a general population sample. Participants ( N = 427) completed the Revised Controlling Behaviors Scale and the Revised Conflict Tactics Scale. Prevalence of perpetration and victimization of controlling behaviors was relatively high, although the frequency and severity of the behaviors was mainly low level. Five clusters were established based on the use of five types of controlling behaviors: economic, threatening, intimidating, emotional, and isolating. Significant differences were found between the perpetration clusters and (a) minor physical assault, (b) severe physical assault, (c) minor psychological aggression, and (d) severe psychological aggression. Furthermore, significant differences were found between the victimization clusters and (a) physical assault, (b) minor psychological aggression, and (c) severe psychological aggression. It is clear that controlling behaviors are a feature within general population relationships, and further research is required to understand when such behaviors become problematic, and what needs to be done to prevent this from happening.

    Understanding of Alzheimer disease is fundamental for early diagnosis and to reduce caregiver burden. The objective of this study is to evaluate the degree of understanding of Alzheimer disease among informal caregivers and different segments of the general population through the Alzheimer's Disease Knowledge Scale. We assessed the knowledge of caregivers in different follow-up periods (less than one year, between 1 and 5 years, and over 5 years since diagnosis) and individuals from the general population. Alzheimer's Disease Knowledge Scale scores were grouped into different items: life impact, risk factors, symptoms, diagnosis, treatment, disease progression, and caregiving. A total of 419 people (215 caregivers and 204 individuals from the general population) were included in the study. No significant differences were found between groups for overall Alzheimer's Disease Knowledge Scale score (19.1 vs. 18.8, P = .9). There is a scarce knowledge of disease risk factors (49.3%) or the care needed (51.2%), while symptoms (78.6%) and course of the disease (77.2%) were the best understood aspects. Older caregiver age was correlated with worse Alzheimer's Disease Knowledge Scale scores overall and for life impact, symptoms, treatment, and disease progression (P < .05). Time since diagnosis improved caregivers' knowledge of Alzheimer disease symptoms (P = .00) and diagnosis (P = .05). Assessing the degree of understanding of Alzheimer disease is essential to the development of health education strategies both in the general population and among caregivers.

    2009-01-01

    In this Letter, we generalize the differential transform method to solve differential-difference equation for the first time. Two simple but typical examples are applied to illustrate the validity and the great potential of the generalized differential transform method in solving differential-difference equation. A Pade technique is also introduced and combined with GDTM in aim of extending the convergence area of presented series solutions. Comparisons are made between the results of the proposed method and exact solutions. Then we apply the differential transform method to the discrete KdV equation and the discrete mKdV equation, and successfully obtain solitary wave solutions. The results reveal that the proposed method is very effective and simple. We should point out that generalized differential transform method is also easy to be applied to other nonlinear differential-difference equation.

    Full Text Available OBJECTIVES This study aims to investigate health disparities between lesbian, gay, and bisexual (LGB adults and the general population in Korea, where there is low public acceptance of sexual minorities and a lack of research on the health of sexual minorities. METHODS The research team conducted a nationwide survey of 2,335 Korean LGB adults in 2016. Using the dataset, we estimated the age-standardized prevalence ratios (SPRs for poor self-rated health, musculoskeletal pain, depressive symptoms, suicidal behaviors, smoking, and hazardous drinking. We then compared the SPRs of the LGB adults and the general population which participated in three different nationally representative surveys in Korea. SPRs were estimated for each of the four groups (i.e., gay men, bisexual men, lesbians, and bisexual women. RESULTS Korean LGB adults exhibited a statistically significantly higher prevalence of depressive symptoms, suicidal ideation and attempts, and musculoskeletal pain than the general population. Lesbian and bisexual women had a higher risk of poor self-rated health and smoking than the general women population, whereas gay and bisexual men showed no differences with the general men population. Higher prevalence of hazardous drinking was observed among lesbians, gay men, and bisexual women compared to the general population, but was not observed in bisexual men. CONCLUSIONS The findings suggest that LGB adults have poorer health conditions compared to the general population in Korea. These results suggest that interventions are needed to address the health disparities of Korean LGB adults.

    The stochastic dynamics of a population growth model, similar to the Von Foerster model for human population, is studied. The influence of fluctuating environment on the carrying capacity is modeled as a multiplicative dichotomous noise. It is established that an interplay between nonlinearity and environmental fluctuations can cause single unidirectional discontinuous transitions of the mean population size versus the noise amplitude, i.e., an increase of noise amplitude can induce a jump from a state with a moderate number of individuals to that with a very large number, while by decreasing the noise amplitude an opposite transition cannot be effected. An analytical expression of the mean escape time for such transitions is found. Particularly, it is shown that the mean transition time exhibits a strong minimum at intermediate values of noise correlation time, i.e., the phenomenon of stochastic resonance occurs. Applications of the results in ecology are also discussed.

    The "Center of Epidemiologic Studies - Depression scale" (CES-D) is a well-known screening tool for depression. Until now the criterion validity of the German version of the CES-D was not investigated in a sample of the adult general population. 508 study participants of the Austrian general population completed the CES-D. ICD-10 diagnoses were established by using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN). Receiver Operating Characteristics (ROC) analysis was conducted. Possible gender differences were explored. Overall discriminating performance of the CES-D was sufficient (ROC-AUC 0,836). Using the traditional cut-off values of 15/16 and 21/22 respectively the sensitivity was 43.2 % and 32.4 %, respectively. The cut-off value developed on the basis of our sample was 9/10 with a sensitivity of 81.1 % und a specificity of 74.3 %. There were no significant gender differences. This is the first study investigating the criterion validity of the German version of the CES-D in the general population. The optimal cut-off values yielded sufficient sensitivity and specificity, comparable to the values of other screening tools. © Georg Thieme Verlag KG Stuttgart · New York.

  16. Prevalence of traumatic brain injury in the general adult population: a meta-analysis.

    2013-01-01

    Traumatic brain injury (TBI) is a significant public-health concern. To understand the extent of TBI, it is important to assess the prevalence of TBI in the general population. However, the prevalence of TBI in the general population can be difficult to measure because of differing definitions of TBI, differing TBI severity levels, and underreporting of sport-related TBI. Additionally, prevalence reports vary from study to study. In this present study, we used meta-analytic methods to estimate the prevalence of TBI in the adult general population. Across 15 studies, all originating from developed countries, which included 25,134 adults, 12% had a history of TBI. Men had more than twice the odds of having had a TBI than did women, suggesting that male gender is a risk factor for TBI. The adverse behavioral, cognitive and psychiatric effects associated with TBI coupled with the high prevalence of TBI identified in this study indicate that TBI is a considerable public and personal-health problem.

    Hepatitis E infection is one of the most frequent causes of acute hepatitis in the world. Currently five human genotypes with different geographical distributions and distinct epidemiologic patterns are identified. In Slovakia, only rare cases of hepatitis E have been reported in past years. Because the most important risk factors associated with HEV infection include consumption of contaminated pork meat and poor hygienic standards, the aim of the study was to evaluate the prevalence of anti-HEV total antibodies and the main risk factors for HEV in the population living in separated and segregated Roma settlements ( n = 195), which represent places with increased risk of infection in Slovakia and to compare it with the prevalence in the general population ( n = 69). Of 264 respondents included in the study, 47 (17.8%) showed positivity for anti-HEV antibodies, 42 of whom were Roma (21.5%, n = 195) and 5 (7.2%, n = 69) non-Roma. The population living in Roma settlements lives in poorer conditions and are at higher risk of HEV in comparison to the general population. However, differences in living conditions within the settlements do not contributed to lower risk of HEV antibody prevalence between Roma living in settlements.

    Pathological eating attitudes and extreme weight control practices occur most commonly in certain female populations. In some young male occupation groups, such as in the armed forces, the appearance of physical strength and muscularity has particular importance. We studied body and eating attitudes and the prevalence of bodybuilding and steroid abuse in 480 military college and 752 general college male students. The Eating Disorder Inventory was used for all subjects. General college students had higher body mass index values than did military students. The prevalence of bodybuilding and steroid abuse was significantly greater in the military population. Comparisons between the study groups and within groups showed significantly different scores on certain Eating Disorder Inventory subscales. The study revealed that male military college students have some protective factors against the psychopathological features of eating disorders.

    2016-04-01

    Most child population is able to undergo dental treatment in the conventional setting. However, some children fail to cope with in-office conscious state and cannot respond to usual management modalities. This review aims to discuss the topic further. A computerized search in databases PubMed, MEDLINE, EMBASE, Google Scholar and Google were performed using dental general anesthesia related keywords. Original and review English-written articles that were limited to child population were retrieved without any limitation of publication date. The suitable papers were selected and carefully studied. A data form designed by author was used to write relevant findings. Preoperative oral examination and comprehensive evaluation of treatment needs is only possible after clinical and radiographic oral examination. Effective collaboration in dental GA team should be made to minimize psychological trauma of children who undergo dental GA. Before conducting comprehensive dental treatment under GA, the general health of the child and the success rate of procedures provided needs to be accurately evaluated. It is noteworthy that determination of the optimal timing for GA dental operation is of great importance. Providing safety with pediatric dental rehabilitation under GA is critical. Besides criteria for case selection of dental GA, some degree of dental practitioner's judgment is required to make decision. Pre- and post-operative instructions to parents or caregiver decrease the risk of complications. However, trained resuscitation providers, careful monitoring and advanced equipment minimize adverse outcomes.

  1. Generalizing Evidence From Randomized Clinical Trials to Target Populations

    Properly planned and conducted randomized clinical trials remain susceptible to a lack of external validity. The authors illustrate a model-based method to standardize observed trial results to a specified target population using a seminal human immunodeficiency virus (HIV) treatment trial, and they provide Monte Carlo simulation evidence supporting the method. The example trial enrolled 1,156 HIV-infected adult men and women in the United States in 1996, randomly assigned 577 to a highly active antiretroviral therapy and 579 to a largely ineffective combination therapy, and followed participants for 52 weeks. The target population was US people infected with HIV in 2006, as estimated by the Centers for Disease Control and Prevention. Results from the trial apply, albeit muted by 12%, to the target population, under the assumption that the authors have measured and correctly modeled the determinants of selection that reflect heterogeneity in the treatment effect. In simulations with a heterogeneous treatment effect, a conventional intent-to-treat estimate was biased with poor confidence limit coverage, but the proposed estimate was largely unbiased with appropriate confidence limit coverage. The proposed method standardizes observed trial results to a specified target population and thereby provides information regarding the generalizability of trial results. PMID:20547574

  6. A General Method for QTL Mapping in Multiple Related Populations Derived from Multiple Parents

    2009-03-01

    Full Text Available It's well known that incorporating some existing populations derived from multiple parents may improve QTL mapping and QTL-based breeding programs. However, no general maximum likelihood method has been available for this strategy. Based on the QTL mapping in multiple related populations derived from two parents, a maximum likelihood estimation method was proposed, which can incorporate several populations derived from three or more parents and also can be used to handle different mating designs. Taking a circle design as an example, we conducted simulation studies to study the effect of QTL heritability and sample size upon the proposed method. The results showed that under the same heritability, enhanced power of QTL detection and more precise and accurate estimation of parameters could be obtained when three F2 populations were jointly analyzed, compared with the joint analysis of any two F2 populations. Higher heritability, especially with larger sample sizes, would increase the ability of QTL detection and improve the estimation of parameters. Potential advantages of the method are as follows: firstly, the existing results of QTL mapping in single population can be compared and integrated with each other with the proposed method, therefore the ability of QTL detection and precision of QTL mapping can be improved. Secondly, owing to multiple alleles in multiple parents, the method can exploit gene resource more adequately, which will lay an important genetic groundwork for plant improvement.

    This cross-cultural study compared explanations of sleep paralysis (SP) in two countries and two groups with different levels of education in one country. Comparisons were made between individuals having experienced SP at least once in a lifetime from Cairo, Egypt (n = 89), Copenhagen, Denmark (n = 59), and the American University in Cairo, Egypt (n = 44). As hypothesized, participants from the general Egyptian population were more likely to endorse supernatural causal explanation of their SP compared to participants from Denmark; participants from the American University in Cairo were less likely to endorse supernatural causes of their SP compared to participants from the general Egyptian population. Moreover, participants from the American University in Cairo were marginally significantly more likely to endorse supernatural causes of their SP compared to participants from Denmark. Additionally, we explored which culturally bound explanations and beliefs about SP existed in Egypt and Denmark. We found that nearly half (48%) of the participants from the general Egyptian population believed their SP to be caused by the Jinn, a spirit-like creature with roots in Islamic tradition, which constitutes a culturally bound interpretation of the phenomenology of SP in this region of the world. Case studies are presented to illustrate these findings.

    Since 1959, a Los Alamos National Laboratory study has analyzed over 5000 tissues from 1100 individuals of the nonoccupationally exposed general population for fallout plutonium. These data have been useful in determining the tissue distributions and the annual baseline levels of environmental plutonium in the United States population. The effects of age, sex, date of death, cause of death and geographic location of resididence on the observed plutonium deposition have been evaluated. Because of the difference in biological turnover times of plutonium in the various organs of the body and the changing concentrations of plutonium in the atmosphere, the plutonium concentration ratios between tissues have changed as a function of time. However, our data indicate that over the past 10 years, the highest concentrations in the general population are found in the tracheobronchial lymph nodes and the liver and the lowest concentrations are in the spleen, gonads and kidney. The median body burdens of plutonium in the US population are estimated to have reached 12 pCi during the 1960's and have declined to about 2 pCi in 1977. Large errors in estimated skeletal burdens of plutonium may exist because of small specimen sample sizes and a lack of knowledge concerning the relative distribution of plutonium among the various bones of the human body

    1983-01-01

    A new national regulation for nuclear power plant siting is described. The main body of the regulation is similar in contents to the IAEA Code of Practice in siting, but exceeds its scope in certain areas and covers all aspects of the impact of the plant on the population and the environment of the region, including non-radiological effects. The regulation is accompanied by appendices which refer to site suitability criteria with respect to the radiological consequences from the operational states of the plant and with respect to accidents, including core-melt accidents; these reflect the particular geographic and demographic situation of Greece

    Full Text Available Abstract Background Understanding the environmental and genetic risk factors of accelerated lung function decline in the general population is a first step in a prevention strategy against the worldwide increasing respiratory pathology of chronic obstructive pulmonary disease (COPD. Deficiency in antioxidative and detoxifying Glutathione S-transferase (GST gene has been associated with poorer lung function in children, smokers and patients with respiratory diseases. In the present study, we assessed whether low activity variants in GST genes are also associated with accelerated lung function decline in the general adult population. Methods We examined with multiple regression analysis the association of polymorphisms in GSTM1, GSTT1 and GSTP1 genes with annual decline in FEV1, FVC, and FEF25–75 during 11 years of follow-up in 4686 subjects of the prospective SAPALDIA cohort representative of the Swiss general population. Effect modification by smoking, gender, bronchial hyperresponisveness and age was studied. Results The associations of GST genotypes with FEV1, FVC, and FEF25–75 were comparable in direction, but most consistent for FEV1. GSTT1 homozygous gene deletion alone or in combination with GSTM1 homozygous gene deletion was associated with excess decline in FEV1 in men, but not women, irrespective of smoking status. The additional mean annual decline in FEV1 in men with GSTT1 and concurrent GSTM1 gene deletion was -8.3 ml/yr (95% confidence interval: -12.6 to -3.9 relative to men without these gene deletions. The GSTT1 effect on the FEV1 decline comparable to the observed difference in FEV1 decline between never and persistent smoking men. Effect modification by gender was statistically significant. Conclusion Our results suggest that genetic GSTT1 deficiency is a prevalent and strong determinant of accelerated lung function decline in the male general population.

    Preoperative teaching and stoma site marking are supported by research and professional organizations as interventions that can reduce the incidence of problematic stomas and improve patient outcomes. This study investigated the translation of this research into practice in the acute care surgery population. A retrospective chart review using convenience sampling was conducted at a large urban hospital in the Midwestern United States. Thirty patients underwent a surgical procedure that resulted in the creation of a fecal ostomy over a 5-month period. Descriptive statistical analysis examined the reason for surgery, preoperative length of stay (LOS), the percentage of patients who received preoperative teaching and stoma marking and the relationship between preoperative LOS and the use of preoperative teaching and stoma marking. Twenty-one of 30 patients were admitted to hospital 24 hours or more before surgery. No participants were admitted urgently. Three (14%) of those admitted for more than 24 hours received preoperative marking or teaching. There was no significant relationship between preoperative LOS and preoperative teaching and stoma marking. The opportunity exists to promote successful adaptation in this surgical population through the implementation of the evidence-based interventions of preoperative teaching and stoma marking. Additional study is needed to determine barriers to their use as well as to develop effective implementation strategies.

  14. On interfaces between cell populations with different mobilities

    Partial differential equations describing the dynamics of cell population densities from a fluid mechanical perspective can model the growth of avascular tumours. In this framework, we consider a system of equations that describes the interaction between a population of dividing cells and a population of non-dividing cells. The two cell populations are characterised by different mobilities. We present the results of numerical simulations displaying two-dimensional spherical waves with sharp interfaces between dividing and non-dividing cells. Furthermore, we numerically observe how different ratios between the mobilities change the morphology of the interfaces, and lead to the emergence of finger-like patterns of invasion above a threshold. Motivated by these simulations, we study the existence of one-dimensional travelling wave solutions.

  15. Theological Discourse in Bioethics: General and Confessional Differencies

    2011-04-01

    Full Text Available This essay is devoted to the problem of theological discourse in bioethics. We focus both on general positions shared across major existing religions and substantial confessional differences among them. Among the major categories determining relationship between bioethics and religion we studied the following: “image of God” (imago Dei, casuistry, primacy of procreation, “playing God”, artificial procreation and others. After analyzing Christian, Jewish and Islamic positions on the theological interpretation of the reproductive technologies and human cloning, we came to a conclusion that differences in views depend rather on orthodox, conservative, traditional or liberal viewpoint within a given church than on differences between particular religions. Despite substantial faith-related differences, occasionally, views on reproductive technologies and other problems of bioethics seem closer between liberal Protestants and liberal Judaists than between orthodox and reformist Judaists.

    After the WHO recommended HPV vaccination of the general population in 2009, government support of HPV vaccination programs was increased in many countries. However, this policy was not implemented in Korea due to perceived low cost-effectiveness. Thus, the aim of this study was to analyze the cost-utility of HPV vaccination programs targeted to high risk populations as compared to vaccination programs for the general population. Each study population was set to 100,000 people in a simulation study to determine the incremental cost-utility ratio (ICUR), then standard prevalence rates, cost, vaccination rates, vaccine efficacy, and the Quality-Adjusted Life-Years (QALYs) were applied to the analysis. In addition, sensitivity analysis was performed by assuming discounted vaccination cost. In the socially vulnerable population, QALYs gained through HPV vaccination were higher than that of the general population (General population: 1,019, Socially vulnerable population: 5,582). The results of ICUR showed that the cost of HPV vaccination was higher for the general population than the socially vulnerable population. (General population: 52,279,255 KRW, Socially vulnerable population: 9,547,347 KRW). Compared with 24 million KRW/QALYs as the social threshold, vaccination of the general population was not cost-effective. In contrast, vaccination of the socially vulnerable population was strongly cost-effective. The results suggest the importance and necessity of government support of HPV vaccination programs targeted to socially vulnerable populations because a targeted approach is much more cost-effective. The implementation of government support for such vaccination programs is a critical strategy for decreasing the burden of HPV infection in Korea.

    Courtship and mating behavior generally evolve rapidly in diverging populations and species. The adaptation to different environments may cause behavioral divergence in characteristics involved in mate choice. Our objective in this study was to compare the sexual behavior of two distant populations of the scorpion Bothriurus bonariensis. This species has a broad distribution in South America, inhabiting Central Argentina, Uruguay and south-eastern Brazil. It is known that in this species there is a divergence in morphological patterns (body size, coloration, allometry and fluctuating asymmetry indexes) among distant populations. Considering the differences in environmental conditions between localities, we compare the sexual behavior in intra-population and inter-population matings from Central Argentina and southern Uruguay populations. We found significant differences in mating patterns, including differences in the frequency and duration of important stimulatory courtship behaviors. In addition, most inter-population matings were unsuccessful. In this framework, the differences in reproductive behavior could indicate reproductive isolation between these populations, which coincides with their already known morphological differences. This is the first study comparing the sexual behavior of allopatric populations of scorpions; it provides new data about the degree of intraspecific geographical divergence in the sexual behavior of B. bonariensis.

    Differences between successful long-term weight loss maintainers and the general population with regard to eating and weighing habits, non-normative eating behaviors, and eating-related and general psychopathological parameters are unknown. Self-identified weight loss maintainers from the German Weight Control Registry (GWCR, n = 494) were compared with a representative sample of the general German population (n = 2,129). The samples did not differ in current BMI. Using the same assessment instruments in both cohorts, a variety of eating-related and psychological variables were determined. The GWCR participants reported more self-weighing and higher eating frequency but less hot meal consumption and more eating-out-of-home. Binge eating, compensatory behaviors, and concerns about shape and weight were reported more often by successful weight loss maintainers. Scores of depression and worrying about health were slightly higher whereas severity of somatic symptoms was less pronounced in the GWCR participants. Overall, our data suggest that successful weight loss maintainers are characterized by more concerns about shape and weight, greater binge eating frequency, and higher use of compensatory behaviors. The latter suggests that weight loss maintenance might not only be achieved by healthy strategies but also by non-normative behaviors which might increase the vulnerability for weight regain. © 2015 The Obesity Society.

    By definition idiopathic generalized epilepsy (IGE) is not associated with structural abnormalities on conventional magnetic resonance imaging (MRI). However, recent quantitative studies suggest white and gray matter alterations in IGE. The purpose of this study was to investigate whether there are white and/or gray matter structural differences between controls and two subsets of IGE, namely juvenile myoclonic epilepsy (JME) and IGE with generalized tonic-clonic seizures only (IGE-GTC). We assessed white matter integrity and gray matter volume using diffusion tensor tractography-based analysis of fractional anisotropy and voxel-based morphometry, respectively, in 25 patients with IGE, all of whom had experienced generalized tonic-clonic convulsions. Specifically, 15 patients with JME and 10 patients with IGE-GTC were compared to two groups of similarly matched controls separately. Correlations between total lifetime generalized tonic-clonic seizures and fractional anisotropy were investigated for both groups. Tractography revealed lower fractional anisotropy in specific tracts including the crus of the fornix, body of corpus callosum, uncinate fasciculi, superior longitudinal fasciculi, anterior limb of internal capsule, and corticospinal tracts in JME with respect to controls, whereas there were no fractional anisotropy differences in IGE-GTC. No correlation was found between fractional anisotropy and total lifetime generalized tonic-clonic seizures for either JME or IGE-GTC. Although false discovery rate-corrected voxel-based morphometry (VBM) showed no gray matter volume differences between patient and control groups, spatial extent cluster-corrected VBM analysis suggested a trend of gray matter volume reduction in frontal and central regions in both patient groups, more lateral in JME and more medial in IGE-GTC. The findings support the idea that the clinical syndromes of JME and IGE-GTC have unique anatomic substrates. The fact that the primary clinical

  8. Cardiometabolic risk indicators that distinguish adults with psychosis from the general population, by age and gender.

    Debra L Foley

    Full Text Available Individuals with psychosis are more likely than the general community to develop obesity and to die prematurely from heart disease. Interventions to improve cardiovascular outcomes are best targeted at the earliest indicators of risk, at the age they first emerge. We investigated which cardiometabolic risk indicators distinguished those with psychosis from the general population, by age by gender, and whether obesity explained the pattern of observed differences. Data was analyzed from an epidemiologically representative sample of 1,642 Australians with psychosis aged 18-64 years and a national comparator sample of 8,866 controls aged 25-64 years from the general population. Cubic b-splines were used to compare cross sectional age trends by gender for mean waist circumference, body mass index [BMI], blood pressure, fasting blood glucose, triglycerides, LDL, HDL, and total cholesterol in our psychosis and control samples. At age 25 individuals with psychosis had a significantly higher mean BMI, waist circumference, triglycerides, glucose [women only], and diastolic blood pressure and significantly lower HDL-cholesterol than controls. With the exception of triglycerides at age 60+ in men, and glucose in women at various ages, these differences were present at every age. Differences in BMI and waist circumference between samples, although dramatic, could not explain all differences in diastolic blood pressure, HDL-cholesterol or triglycerides but did explain differences in glucose. Psychosis has the hallmarks of insulin resistance by at least age 25. The entire syndrome, not just weight, should be a focus of intervention to reduce mortality from cardiovascular disease.

    Prevalence studies of Internet addiction in the general population are rare. In addition, a lack of approved criteria hampers estimation of its occurrence. This study conducted a latent class analysis (LCA) in a large general population sample to estimate prevalence. A telephone survey was conducted based on a random digit dialling procedure including landline telephone (n=14,022) and cell phone numbers (n=1,001) in participants aged 14-64. The Compulsive Internet Use Scale (CIUS) served as the basis for a LCA used to look for subgroups representing participants with Internet addiction or at-risk use. CIUS was given to participants reporting to use the Internet for private purposes at least 1 h on a typical weekday or at least 1 h on a day at the weekend (n=8,130). A 6-class model showed best model fit and included two groups likely to represent Internet addiction and at-risk Internet use. Both groups showed less social participation and the Internet addiction group less general trust in other people. Proportions of probable Internet addiction were 1.0% (CI 0.9-1.2) among the entire sample, 2.4% (CI 1.9-3.1) in the age group 14-24, and 4.0% (CI 2.7-5.7) in the age group 14-16. No difference in estimated proportions between males and females was found. Unemployment (OR 3.13; CI 1.74-5.65) and migration background (OR 3.04; CI 2.12-4.36) were related to Internet addiction. This LCA-based study differentiated groups likely to have Internet addiction and at-risk use in the general population and provides characteristics to further define this rather new disorder. © 2013 S.

    Perfluorooctanesulfonate (PFOS) was found to be widespread in human populations and wildlife Major applications of these POSF-based products have included surfactants in: specialty paper and packaging products, carpet, upholstery, and textile products and in certain insecticide formulation. Depending on the specific functional derivatization or the degree of polymerization, such POSF based products may degrade or metabolize to PFOS, a stable and persistent end product that has the potential to bioaccumulate in the food chain. The mechanisms and pathways leading to the presence of PFOS in human blood are not well characterized but likely involve environmental and dietary exposure to PFOS or to precursor molecules of PFOS. PFOS and related perfluorinated compounds have recently been detected at low parts per billion (nanogram per milliliter) concentrations in the general population from 10 different countries including Korea. In the present report, the levels of perfluoroalkylated compounds in the general population from Korea were analyzed with respect to occupation, smoking status, sex, age and socio-economic status. The degree of association between the four target fluorochemicals measured in this study (PFOS, PFHxS, PFOA, and PFOSA) were also analyzed by linear regression to determine the potential association between their sources of exposure.

    This study investigated the prevalence of contact sensitization in a general adult population and the relationship between the history of metal dermatitis and sensitization to metal allergens. A cross-sectional population study using patch tests and a questionnaire was conducted among adults in Tromsø, Northern Norway. A random sample of 830 participants aged 18-75 years were invited to participate in the patch testing and completed a 1-page self-administered questionnaire. Of the adults, 531 (64%) were actually TRUE tested (using a standardized, ready-to-apply patch test system) and completed the self-administered questionnaire about ear piercing, metal reactions, skin reactions to different allergens, atopic dermatitis, eczema, cooking equipment and diet. The study showed that nickel (19.2%; women 31.1% and men 5.0%), fragrance mix (3.4%) and cobalt (1.7%) were the most prevalent allergens causing contact sensitization. For all other allergens, less than 1.1% tested positive. Eighty-four (45.2%) subjects with a positive history of metal dermatitis had negative patch tests. Contact sensitization was found frequently in this general adult population, especially to nickel and perfumes with a predominance among females. An eczematous reaction caused by cheap earrings seemed to be the best indicator for metal sensitivity.

    Attentional-interference using emotional Stroop tasks (ESTs) is greater among individuals in the general population with positive (versus negative) schizotypal traits; specifically in response to negatively (versus positively) valenced words, potentially capturing threat-sensitivity. Variability in attentional-interference as a function of subcategories of negatively valenced words (and in relation to schizotypal traits) remains underexplored in EST studies. We examined attentional-interference across negative word subcategories (fear/anger/sadness/disgust), and in relation to positive schizotypy, among non-clinical individuals in the general population reporting varying degrees of schizotypal traits. As hypothesized, performance differed across word subcategories, though the pattern varied from expectation. Attentional-interference was greater for fear and sadness compared to anger; and analogous for fear, disgust, and sadness. In the high schizotypy group, positive schizotypal traits were directly associated with attentional-interference to disgust. Attentional-interference was comparable between high- and low-positive schizotypy. Results suggest negative emotion subcategories may differentially reflect threat-sensitivity. Disgust-sensitivity may be particularly salient in (non-clinical) positive schizotypy. Findings have implications for understanding negative emotion specificity and variability in stimulus presentation modality when studying threat-related attentional-interference. Finally, disgust-related attentional-interference may serve as a cognitive correlate of (non-clinical) positive schizotypy. Expanding this research to prodromal populations will help explore disgust-related attentional-interference as a potential cognitive marker of positive symptoms.

    2018-05-01

    The population dynamics of two interacting species modeled by the Lotka-Volterra (LV) model with general parameters that can promote or suppress the other species is studied. It is found that the properties of the two species' isoclines determine the interaction of species, leading to six regimes in the phase diagram of interspecies interaction; i.e., there are six different interspecific relationships described by the LV model. Four regimes allow for nontrivial species coexistence, among which it is found that three of them are stable, namely, weak competition, mutualism, and predator-prey scenarios can lead to win-win coexistence situations. The Lyapunov function for general nontrivial two-species coexistence is also constructed. Furthermore, in the presence of spatial diffusion of the species, the dynamics can lead to steady wavefront propagation and can alter the population map. Propagating wavefront solutions in one dimension are investigated analytically and by numerical solutions. The steady wavefront speeds are obtained analytically via nonlinear dynamics analysis and verified by numerical solutions. In addition to the inter- and intraspecific interaction parameters, the intrinsic speed parameters of each species play a decisive role in species populations and wave properties. In some regimes, both species can copropagate with the same wave speeds in a finite range of parameters. Our results are further discussed in the light of possible biological relevance and ecological implications.

  15. A Role for the X Chromosome in Sex Differences in Variability in General Intelligence?

    Johnson, Wendy; Carothers, Andrew; Deary, Ian J

    2009-11-01

    There is substantial evidence that males are more variable than females in general intelligence. In recent years, researchers have presented this as a reason that, although there is little, if any, mean sex difference in general intelligence, males tend to be overrepresented at both ends of its overall distribution. Part of the explanation could be the presence of genes on the X chromosome related both to syndromal disorders involving mental retardation and to population variation in general intelligence occurring normally. Genes on the X chromosome appear overrepresented among genes with known involvement in mental retardation, which is consistent with a model we developed of the population distribution of general intelligence as a mixture of two normal distributions. Using this model, we explored the expected ratios of males to females at various points in the distribution and estimated the proportion of variance in general intelligence potentially due to genes on the X chromosome. These estimates provide clues to the extent to which biologically based sex differences could be manifested in the environment as sex differences in displayed intellectual abilities. We discuss these observations in the context of sex differences in specific cognitive abilities and evolutionary theories of sexual selection. © 2009 Association for Psychological Science.

Unfortunately, effective treatment is often impeded by stigmatizing attitudes of other individuals, which have been found to lead to a number of negative consequences including reduced help-seeking behavior and increased social distance. Despite the high prevalence of depression in Canada, little research has been conducted to examine stigma against depression in the Canadian general population. Such information is crucial to understanding the current state of stigmatizing attitudes in the Canadian communities, and framing future stigma reduction initiatives. The objectives of this study were to estimate the percentages of various stigmatizing attitudes toward depression in a general population sample and to compare the percentages by demographics and socioeconomic characteristics. Methods We conducted a cross-sectional telephone survey in Alberta, Canada, between February and June 2006. Random digit dialing was used to recruit participants who were aged 18-74 years old (n = 3047. Participants were presented a case vignette describing a depressed individual, and responded to a 9-item Personal Stigma questionnaire. The percentages of stigmatizing attitudes were estimated and compared by demographic and socioeconomic variables. Results Among the participants, 45.9% endorsed that depressed individuals were unpredictable and 21.9% held the view that people with depression were dangerous. Significant differences in stigmatizing attitudes were found by gender, age, education, and immigration status. A greater proportion of men than women held stigmatizing views on each stigma item. No consistent trend emerged by age in stigma against depression. Participants with higher levels of education reported less stigmatizing attitudes than those with less education. Participants who were not born in Canada were more likely to hold

    Although evidence suggests that there is an increase in suicide rates in the general population following celebrity suicide, the rates are heterogeneous across celebrities and countries. It is unclear which is the more vulnerable population according to the effect sizes of celebrity suicides to general population. All suicide victims in the general population verified by the Korea National Statistical Office and suicides of celebrity in South Korea were included for 7 years from 2005 to 2011. Effect sizes were estimated by comparing rates of suicide in the population one month before and after each celebrity suicide. The associations between suicide victims and celebrities were examined. Among 94,845 suicide victims, 17,209 completed suicide within one month after 13 celebrity suicides. Multivariate logistic regression analyses revealed that suicide victims who died after celebrity suicide were significantly likely to be of age 20-39, female, and to die by hanging. These qualities were more strongly associated among those who followed celebrity suicide with intermediate and high effect sizes than lower. Younger suicide victims were significantly associated with higher effect size, female gender, white collar employment, unmarried status, higher education, death by hanging, and night-time death. Characteristics of celebrities were significantly associated with those of general population in hanging method and gender. Individuals who commit suicide after a celebrity suicide are likely to be younger, female, and prefer hanging as method of suicide, which are more strongly associated in higher effect sizes of celebrity suicide.

    The European Roma represent a transnational mosaic of minority population groups with different migration histories and contrasting experiences in their interactions with majority populations across the European continent. Although historical genetic contributions of European lineages to the Roma pool were investigated before, the extent of contemporary genetic admixture between Bayash Roma and non-Romani majority population remains elusive. The aim of this study was to assess the genetic structure of the Bayash Roma population from northwestern Croatia and the general Croatian population and to investigate the extent of admixture between them. A set of genetic data from two original studies (100 Bayash Roma from northwestern Croatia and 195 individuals from the general Croatian population) was analyzed by Bayesian clustering implemented in STRUCTURE software. By re-analyzing published data we intended to focus for the first time on genetic differentiation and structure and in doing so we clearly pointed to the importance of considering social phenomena in understanding genetic structuring. Our results demonstrated that two population clusters best explain the genetic structure, which is consistent with social exclusion of Roma and the demographic history of Bayash Roma who have settled in NW Croatia only about 150 years ago and mostly applied rules of endogamy. The presence of admixture was revealed, while the percentage of non-Croatian individuals in general Croatian population was approximately twofold higher than the percentage of non-Romani individuals in Roma population corroborating the presence of ethnomimicry in Roma.

    The aim of this paper is to study the effect of external photon radiation on the mortality of two populations of French nuclear workers: workers exposed only to external photon radiation and workers potentially exposed also to internal contamination or to neutrons. External photon radiation has been measured through individual dosimeters. Potential exposure to internal contamination or to neutrons has been assessed by experts on the basis of quantitative measurements or of worksite and type of activity. The mortality observed in each population was compared with that expected from national mortality statistics, by computing standardized mortality ratios. Dose-effect relationships were analyzed through trend tests and log-linear Poisson regressions. 14,796 workers were exposed only to external photon radiation; 14,408 workers were also potentially exposed to internal radiation or to neutrons. Between 1968 and 1994, the number of deaths is respectively, 645 and 1,197. The mean external photon dose was respectively, 3.7 and 12.9 mSv. Similar Healthy Worker Effects were observed in the two populations (SMR = 0.59). SMR of 2.41 90% CI [1.39-3.90] was observed for malignant melanoma among workers of the second population. Significant dose-effect relationships were observed: among workers exposed only to external photon radiation for leukemia except CLL and in the other population, for cancers and other diseases related to tobacco or alcohol consumption. Results differed between the two populations. The increase in leukemia risk with dose in the first population will have to be confirmed with extended follow-up. In the other population, results may have been confounded by alpha-emitters inhalation, tobacco, or alcohol consumption.

  2. A general population genetic framework for antagonistic selection that accounts for demography and recurrent mutation.

    Antagonistic selection--where alleles at a locus have opposing effects on male and female fitness ("sexual antagonism") or between components of fitness ("antagonistic pleiotropy")--might play an important role in maintaining population genetic variation and in driving phylogenetic and genomic patterns of sexual dimorphism and life-history evolution. While prior theory has thoroughly characterized the conditions necessary for antagonistic balancing selection to operate, we currently know little about the evolutionary interactions between antagonistic selection, recurrent mutation, and genetic drift, which should collectively shape empirical patterns of genetic variation. To fill this void, we developed and analyzed a series of population genetic models that simultaneously incorporate these processes. Our models identify two general properties of antagonistically selected loci. First, antagonistic selection inflates heterozygosity and fitness variance across a broad parameter range--a result that applies to alleles maintained by balancing selection and by recurrent mutation. Second, effective population size and genetic drift profoundly affect the statistical frequency distributions of antagonistically selected alleles. The "efficacy" of antagonistic selection (i.e., its tendency to dominate over genetic drift) is extremely weak relative to classical models, such as directional selection and overdominance. Alleles meeting traditional criteria for strong selection (N(e)s > 1, where N(e) is the effective population size, and s is a selection coefficient for a given sex or fitness component) may nevertheless evolve as if neutral. The effects of mutation and demography may generate population differences in overall levels of antagonistic fitness variation, as well as molecular population genetic signatures of balancing selection.

    Small populations are likely to have a low genetic ability for disease resistance due to loss of genetic variation through inbreeding and genetic drift. In vertebrates, the highest genetic diversity of the immune system is located at genes within the major histocompatibility complex (MHC). Interestingly, parasite-mediated selection is thought to potentially maintain variation at MHC loci even in populations that are monomorphic at other loci. Therefore, general loss of genetic variation in the genome may not necessarily be associated with low variation at MHC loci. We evaluated inter- and intrapopulation variation in MHC genotypes between an inbred (Aldra) and a relatively outbred population (Hestmannøy) of house sparrows (Passer domesticus) in a metapopulation at Helgeland, Norway. Genomic (gDNA) and transcribed (cDNA) alleles of functional MHC class I and IIB loci, along with neutral noncoding microsatellite markers, were analyzed to obtain relevant estimates of genetic variation. We found lower allelic richness in microsatellites in the inbred population, but high genetic variation in MHC class I and IIB loci in both populations. This suggests that also the inbred population could be under balancing selection to maintain genetic variation for pathogen resistance.

    Study Objectives: To evaluate the association between objective sleep measures and metabolic syndrome (MS), hypertension, diabetes, and obesity. Design: Cross-sectional study. Setting: General population sample. Participants: There were 2,162 patients (51.2% women, mean age 58.4 ± 11.1). Interventions: Patients were evaluated for hypertension, diabetes, overweight/obesity, and MS, and underwent a full polysomnography (PSG). Measurements and Results: PSG measured variables included: total sleep time (TST), percentage and time spent in slow wave sleep (SWS) and in rapid eye movement (REM) sleep, sleep efficiency and arousal index (ArI). In univariate analyses, MS was associated with decreased TST, SWS, REM sleep, and sleep efficiency, and increased ArI. After adjustment for age, sex, smoking, alcohol, physical activity, drugs that affect sleep and depression, the ArI remained significantly higher, but the difference disappeared in patients without significant sleep disordered breathing (SDB). Differences in sleep structure were also found according to the presence or absence of hypertension, diabetes, and overweight/obesity in univariate analysis. However, these differences were attenuated after multivariate adjustment and after excluding subjects with significant SDB. Conclusions: In this population-based sample we found significant associations between sleep structure and metabolic syndrome (MS), hypertension, diabetes, and obesity. However, these associations were cancelled after multivariate adjustment. We conclude that normal variations in sleep contribute little if any to MS and associated disorders.

    The Levels of Emotional Awareness Scale (LEAS) developed by Lane et al. (1990) measures the ability of a subject to discriminate his or her own emotional state and that of others. The scale is based on a cognitive-developmental model in which emotional awareness increases in a similar fashion to intellectual functions. Because studies performed using North American and German populations have demonstrated an effect of age, gender, and level of education on the ability to differentiate emotional states, our study attempts to evaluate whether these factors have the same effects in a general French population. 750 volunteers (506 female, 244 male), who were recruited from three regions of France (Lille, Montpellier, Paris), completed the LEAS. The sample was divided into five age groups and three education levels. The results of the LEAS scores for self and others and the total score showed a difference in the level of emotional awareness for different age groups, by gender and education level. A higher emotional level was observed for younger age groups, suggesting that emotional awareness depends on the cultural context and generational societal teachings. Additionally, the level of emotional awareness was higher in women than in men and lower in individuals with less education. This result might be explained by an educational bias linked to gender and higher education whereby expressive ability is reinforced. In addition, given the high degree of variability in previously observed scores in the French population, we propose a standard based on our French sample.

    Full Text Available Prevalence of generalised anxiety disorders is widespread in Great Britain. Previous small-scale research has shown variations in minor tranquiliser prescribing, identifying several potential predictors of prescribing volume. Objective: This study aimed to investigate the relationship between general practice minor tranquiliser prescribing rates and practice population and general practice characteristics for all general practices in England.Methods: Multiple regression analysis of minor tranquiliser prescribing volumes during 2004/2005 for 8,291 English general practices with general practice and population variables obtained from the General Medical Services (GMS statistics, Quality and Outcomes Framework (QOF, 2001 Census and 2004 Index of Multiple Deprivation (IMD. Results: The highest rates of minor tranquiliser prescribing were in areas with the greatest local deprivation while general practices situated in areas with larger proportions of residents of black ethnic origin had lower rates of prescribing. Other predictors of increased prescribing were general practices with older general practitioners and general practices with older registered practice populations.Conclusion: Our findings show that there is wide variation of minor tranquilisers prescribing across England which has implications regarding access to treatment and inequity of service provision. Future research should determine the barriers to equitable prescribing amongst general practices serving larger populations of black ethnic origin.

    In a healthy organization, psychological health and physical health are as important as production and productivity; and healthy workers have higher productivity. Regarding lack of information about workers' general health profile in Qom Province, this study aimed to assess and compare the staffs' general health and its components among different workplaces in 2014. In a cross-sectional study, 2,276 employees working at 46 industries and organizations completed a standardized General Health Questionnaire (GHQ 28) and a demographic questionnaire. Data were analyzed using t-test, ANOVA, and Pearson product-moment correlation coefficient by IBM SPSS version 20. The mean age of the participants was 32.22 (±7.55) years. Seventy-nine point four percent of participants were married and the rest were single. Highest and lowest scores belonged to social dysfunction and depression, respectively. Also, total score of staffs' general health was 17.87 ± 10.93. The results showed that, in spite of the non-relationship between general health score difference among married and single personnel (p > 0.05), there was a significant difference between men and women and among organizations and industries with regards to general health score (p creativity in the workplaces are at risk. Altogether, the general health score in the studied population was suitable in its entirety.

    General self-efficacy has been historically assumed to have universal health implications. However, less is known about population differences in long-term health effects of general self-efficacy across diverse populations. This study compared black and white American adults for (1) the association between psychosocial and health factors and general self-efficacy at baseline, and (2) the association between baseline self-efficacy and long-term risk of all-cause mortality over 25 years. The Americans' Changing Lives (ACL) study, 1986-2011, is a nationally representative longitudinal cohort of US adults. The study followed 3361 black (n = 1156) and white (n = 2205) adults for up to 25 years. General self-efficacy as well as demographics, socioeconomics, stressful life events, health behaviors, obesity, depressive symptoms, and self-rated health were measured at baseline in 1986. The outcome was time to all-cause mortality since 1986. Race was the focal moderator. Logistic regression and proportional hazards models were used for data analysis. Although blacks had lower general self-efficacy, this association was fully explained by socioeconomic factors (education and income). Our logistic regression suggested interactions between race and education, self-rated health, and stress on general self-efficacy at baseline. Baseline general self-efficacy was associated with risk of mortality in the pooled sample. Race interacted with baseline general self-efficacy on mortality risk, suggesting stronger association for whites than blacks. Black-white differences exist in psychosocial and health factors associated with self-efficacy in the USA. Low general self-efficacy does not increase mortality risk for blacks. Future research should test whether socioeconomic status, race-related attitudes, world views, attributions, and locus of control can potentially explain why low self-efficacy is not associated with higher risk of mortality among American blacks.

    Findings on stigmatizing attitudes toward individuals with schizophrenia have been inconsistent in comparisons between mental health professionals and members of the general public. In this regard, it is important to obtain data from understudied sociocultural settings, and to examine how attitudes toward mental illness vary in such settings. Nationwide samples of 1015 general population individuals and 1414 psychiatrists from Brazil were recruited between 2009 and 2010. Respondents from the general population were asked to identify an unlabeled schizophrenia case vignette. Psychiatrists were instructed to consider "someone with stabilized schizophrenia". Stereotypes, perceived prejudice and social distance were assessed. For the general population, stigma determinants replicated findings from the literature. The level of the vignette's identification constituted an important correlate. For psychiatrists, determinants correlated in the opposite direction. When both samples were compared, psychiatrists showed the highest scores in stereotypes and perceived prejudice; for the general population, the better they recognized the vignette, the higher they scored in those dimensions. Psychiatrists reported the lowest social distance scores compared with members of the general population. Knowledge about schizophrenia thus constituted an important determinant of stigma; consequently, factors influencing stigma should be further investigated in the general population and in psychiatrists as well.

    Despite improved health, unemployment has increased among people living with HIV (PlwHIV) over the last decade. However, since the economic recession of 2008, unemployment also increased in the French general population. This paper aimed to determine if the increase in the unemployment rate in the HIV population was higher than that in the French general population. We used data from the ANRS-Vespa study, a repeated cross-sectional survey among two national representative samples of PlwHIV followed at hospitals in France in 2003 and 2011. We compared employment and unemployment rates between HIV-infected people (overall and according to period of HIV diagnosis) and the French general population in 2003 and 2011, using multivariate Poisson regressions adjusted for individual sociodemographic characteristics. The employment rate among PlwHIV was consistently lower than that in the general population in 2003 and 2011. In contrast, there was a trend of an increasing unemployment rate difference between PlwHIV and the general population: PlwHIV's unemployment rate was 1.48 (95% confidence interval [CI]: 1.16-1.90) times higher than that of the general population in 2003, versus 1.62 (95% CI: 1.34-1.96) times higher in 2011. This unemployment rate difference was the highest for PlwHIV diagnosed in or after 2008 (adjusted prevalence rate ratio: 2.06; 95% CI: 1.59-2.67). These results suggest that in time of economic recession, an increasing proportion of PlwHIV may be excluded from the labor market although they are willing to re-enter it. This constitutes a major issue relative to social consequences of chronic disease.

    Previous qualitative and survey studies have suggested women with spinal cord injury (SCI) are screened less often for cervical cancer compared with the general population. We investigated whether cervical cancer screening rates differ between population-based women with and without traumatic SCI, matched for age and geography. A double cohort design was used, comparing women with SCI to the general population (1:4) using administrative data for Ontario, Canada. Women with SCI, identified using the Discharge Abstract Database for the fiscal years 1995-1996 to 2001-2002, were female residents of Ontario between the ages of 25 and 66, admitted to an acute care facility with a traumatic SCI (ICD-9 CM code 806 or 952). Women in the general Ontario population were randomly matched by age and geography. Screening rates were calculated from fee codes related to Papanicolaou (Pap) smear tests for a 3-year period preinjury and postinjury. There were 339 women with SCI matched to 1506 women in the general Ontario population. Screening rates pre-SCI were 55% for women with SCI and 57% during this same time period for matched women in the general population; post-SCI rates were 58% for both the two groups. Factors predicting the likelihood of receiving a Pap test for SCI cases included younger age and higher socioeconomic status. Utilization data suggest that there are no significant differences in screening rates for women with SCI compared with the general population. However, screening rates for women with SCI were significantly influenced by age as well as income.

    To evaluate the influence of lifestyle factors on the prevalence of rheumatoid arthritis (RA) by comparing Roman Catholic nuns and the general female population. RA prevalence in the general population was evaluated using a standardized telephone survey in 1857 homes taken at random. Individuals who reported an inflammatory joint disease were contacted by a rheumatologist of our unit, missing data were collected from the general practitioner or rheumatologist with the patient's permission, and if necessary a physical examination was done by a rheumatologist. The 9 largest Roman Catholic nun communities in Brittany were screened using the same standardized questionnaire administered face-to-face; nuns who reported an inflammatory joint disease were interviewed and examined by rheumatologists. In both populations, RA was diagnosed when (1) the rheumatologist of our unit who interviewed the patient considered the RA classification criteria positive and (2) the rheumatologist who examined the patient gave a diagnosis of RA independently from RA classification criteria. Data were available for 1706 adult females in the general population and 721 nuns. Of the 20 nuns who reported RA or polyarthritis, 11 received a diagnosis of RA (prevalence 1.52%). The prevalences adjustedfor the French population after 40 years were 1.66% (95% confidence interval, 0.84-2.44) and 1.33 (0.27-2.40) among the nuns and the general female population, respectively. Although our nun population was too small for definite conclusions, we found no evidence of a difference in RA prevalence among nuns and the general female population in Brittany.

    The estimation of population allele frequencies using sample data forms a central component of studies in population genetics. These estimates can be used to test hypotheses on the evolutionary processes governing changes in genetic variation among populations. However, existing studies frequently do not account for sampling uncertainty in these estimates, thus compromising their utility. Incorporation of this uncertainty has been hindered by the lack of a method for constructing confidence intervals containing the population allele frequencies, for the general case of sampling from a finite diploid population of any size. In this study, we address this important knowledge gap by presenting a rigorous mathematical method to construct such confidence intervals. For a range of scenarios, the method is used to demonstrate that for a particular allele, in order to obtain accurate estimates within 0.05 of the population allele frequency with high probability (> or = 95%), a sample size of > 30 is often required. This analysis is augmented by an application of the method to empirical sample allele frequency data for two populations of the checkerspot butterfly (Melitaea cinxia L.), occupying meadows in Finland. For each population, the method is used to derive > or = 98.3% confidence intervals for the population frequencies of three alleles. These intervals are then used to construct two joint > or = 95% confidence regions, one for the set of three frequencies for each population. These regions are then used to derive a > or = 95%% confidence interval for Jost's D, a measure of genetic differentiation between the two populations. Overall, the results demonstrate the practical utility of the method with respect to informing sampling design and accounting for sampling uncertainty in studies of population genetics, important for scientific hypothesis-testing and also for risk-based natural resource management.

    Hepatitis B, C, and D virus (HBV, HCV, and HDV) infections are known to be prevalent in injection drug users (IDUs); however, the relationship between the molecular epidemiologic features of hepatitis virus infection in high-risk individuals and the general population has not yet been established. In total, 1049 IDUs and 672 individuals who underwent physical examinations at Chenzhou hospital, Hunan Province, China, were enrolled. HBV, HCV, and HDV infections were screened with serologic tests in both populations. HBsAg-positive, anti-HCV IgG-positive, and anti-HDV IgG-positive samples were further confirmed by polymerase chain reaction, quantitative polymerase chain reaction, and DNA sequencing. Significantly higher HBV (21.54 vs 16.52%, P = 0.01), HCV (45.95% vs 1.34%, P infections were detected in IDUs compared with the general population. The dual infection of HBV/HCV or HBV/HDV was also significantly higher in IDUs than in the general population. HBV genotype B and HDV genotype II were dominants in both populations. HCV infection showed genotype 6a (49.52%) dominant in IDUs, but genotype 1b accounted for 50% infection, which was followed by genotype 6a (33.33%) in the general population. Higher viral loads were associated with HBV genotype B and HCV genotype 6a compared with non-dominant genotypic infections. HBV and HDV infections shared similar patterns by IDUs and the general populations, and HCV infection exhibited distinct features between two populations. Our results suggest different molecular epidemiologic characteristics of HBV, HCV, and HDV infection in two populations. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    2017-08-01

    Most models of auditory cortical (AC) population coding have focused on primary auditory cortex (A1). Thus our understanding of how neural coding for sounds progresses along the cortical hierarchy remains obscure. To illuminate this, we recorded from two AC fields: A1 and middle lateral belt (ML) of rhesus macaques. We presented amplitude-modulated (AM) noise during both passive listening and while the animals performed an AM detection task ("active" condition). In both fields, neurons exhibit monotonic AM-depth tuning, with A1 neurons mostly exhibiting increasing rate-depth functions and ML neurons approximately evenly distributed between increasing and decreasing functions. We measured noise correlation ( r noise ) between simultaneously recorded neurons and found that whereas engagement decreased average r noise in A1, engagement increased average r noise in ML. This finding surprised us, because attentive states are commonly reported to decrease average r noise We analyzed the effect of r noise on AM coding in both A1 and ML and found that whereas engagement-related shifts in r noise in A1 enhance AM coding, r noise shifts in ML have little effect. These results imply that the effect of r noise differs between sensory areas, based on the distribution of tuning properties among the neurons within each population. A possible explanation of this is that higher areas need to encode nonsensory variables (e.g., attention, choice, and motor preparation), which impart common noise, thus increasing r noise Therefore, the hierarchical emergence of r noise -robust population coding (e.g., as we observed in ML) enhances the ability of sensory cortex to integrate cognitive and sensory information without a loss of sensory fidelity. NEW & NOTEWORTHY Prevailing models of population coding of sensory information are based on a limited subset of neural structures. An important and under-explored question in neuroscience is how distinct areas of sensory cortex differ in their

    2004-01-01

    Homozygosity for mutations in ABC transporter A1 (ABCA1) causes Tangier disease, a rare HDL-deficiency syndrome. Whether heterozygosity for genetic variation in ABCA1 also contributes to HDL cholesterol (HDL-C) levels in the general population is presently unclear. We determined whether mutations...... or single-nucleotide polymorphisms (SNPs) in ABCA1 were overrepresented in individuals with the lowest 1% (n=95) or highest 1% (n=95) HDL-C levels in the general population by screening the core promoter and coding region of ABCA1. For all nonsynonymous SNPs identified, we determined the effect of genotype...... on lipid traits in 9,259 individuals from the general population. Heterozygosity for ABCA1 mutations was identified in 10% of individuals with low HDL-C only. Three of 6 nonsynonymous SNPs (V771M, V825I, and R1587K) were associated with increases or decreases in HDL-C in women in the general population...

    Periodontal disease is a chronic inflammatory disease resulting in destruction of tissues and structures surrounding the teeth thus, if left untreated causes loss of teeth and ultimately results in edentulism, posing a great negative impact on individuals' quality of life. Hence the global epidemiological data suggests periodontal disease to be one of a major burden on oral diseases. To reduce this burden it is necessary to know the true prevalence of the disease according to which proper initiatives can be formulated. India being home to nearly 1.2 billion people and one amongst the rapidly developing country, its population requires being systemically as well as orally healthy to lead a good quality of life. However due to large heterogenecity amongst its residing population in terms of geographical area, culture, education, socioeconomic status, a variety of oral diseases like periodontal diseases are prevalent here. Even though the early studies suggested that the population is highly susceptible to the disease, the true prevalence of periodontal disease has not been found yet due to paucity in literature available. To systematically review the available literature taken from various parts of India and find the prevalence rate of periodontal disease amongst the general population of India. A literature search was performed using PUB MED, COCHRANE and EMBASE databases on August 6, 2015. Following full text assessment a thorough references search was made and potential studies were included. A Quality assessment of retrieved articles from 2(nd) round was done using a self designed questionnaire and only field survey studies were included in the systematic review. The literature search yielded six studies which had performed field surveys to find the prevalence of periodontal disease in their respective areas. These studies have observed different sets of age groups and the same has been accomplished by using Community Periodontal Index (CPI) or Community

  9. The Role of Self-Compassion in Buffering Symptoms of Depression in the General Population.

    Annett Körner

    Full Text Available Self-compassion, typically operationalized as the total score of the Self-Compassion Scale (SCS; Neff, 2003b, has been shown to be related to increased psychological well-being and lower depression in students of the social sciences, users of psychology websites and psychotherapy patients. The current study builds on the existing literature by examining the link between self-compassion and depressive symptomatology in a sample representative of the German general population (n = 2,404. The SCS subscales of self-judgment, isolation, and over-identification, and the "self-coldness", composite score, which encompass these three negative subscales, consistently differed between subsamples of individuals without any depressive symptoms, with any depressive syndromes, and with major depressive disorder. The contribution of the positive SCS subscales of self-kindness, common humanity, and mindfulness to the variance in depressive symptomatology was almost negligible. However, when combined to a "self-compassion composite", the positive SCS subscales significantly moderated the relationship between "self-coldness" and depressive symptoms in the general population. This speaks for self-compassion having the potential to buffer self-coldness related to depression--providing an argument for interventions that foster self-caring, kind, and forgiving attitudes towards oneself.

    Rodríguez-Míguez, Eva; Mosquera Nogueira, Jacinto

    To estimate the intangible effects of alcohol misuse on the drinker's quality of life, based on general population preferences METHODS: The most important effects (dimensions) were identified by means of two focus groups conducted with patients and specialists. The levels of these dimensions were combined to yield different scenarios. A sample of 300 people taken from the general Spanish population evaluated a subset of these scenarios, selected by using a fractional factorial design. We used the probability lottery equivalent method to derive the utility score for the evaluated scenarios, and the random-effects regression model to estimate the relative importance of each dimension and to derive the utility score for the rest of scenarios not directly evaluated. Four main dimensions were identified (family, physical health, psychological health and social) and divided into three levels of intensity. We found a wide variation in the utilities associated with the scenarios directly evaluated (ranging from 0.09 to 0.78). The dimensions with the greatest relative importance were physical health (36.4%) and family consequences (31.3%), followed by psychological (20.5%) and social consequences (11.8%). Our findings confirm the benefits of adopting a heterogeneous approach to measure the effects of alcohol misuse. The estimated utilities could have both clinical and economic applications.

    Medical prescriptions for opioids as well as their non-medical use have increased in Canada in recent years. This study aimed to estimate the number of non-medical prescription opioid (PO) users in the general and street drug using populations in Canada. The number of non-medical PO users among the general population and the number of non-medical PO users, heroin users, or both among the street drug using population was estimated for Canada and for the most populous Canadian provinces. Different estimation methods were used: 1) the number of non-medical PO users in the Canadian general population was estimated based on Canadian availability data, and the ratio of US availability to non-medical PO use from US survey data; 2) numbers within the street drug using population were indirectly estimated based on overdose death data, and a key informants survey. Distribution and trends by usage of opioids were determined by using the multi-site Canadian OPICAN cohort data. Between 321,000 to 914,000 non-medical PO users were estimated to exist among the general population in Canada in 2003. The estimated number of non-medical PO users, heroin users, or both among the street drug using population was about 72,000, with more individuals using nonmedical PO than heroin in 2003. Based on data from the OPICAN survey, in 2005 the majority of the street drug using population in main Canadian cities was non-medical PO users, with the exception of Vancouver and Montreal. A relative increase of 24% was observed from 2002 to 2005 in the proportion of the street drug using population who used non-medical POs only. There is an urgent need to further assess the extent and patterns of non-medical prescription opioid use, related problems and drug distribution channels in Canada.

    Full Text Available Abstract Background Changes in gene regulation are thought to be crucial for the adaptation of organisms to their environment. Transcriptome analyses can be used to identify candidate genes for ecological adaptation, but can be complicated by variation in gene expression between tissues, sexes, or individuals. Here we use high-throughput RNA sequencing of a single Drosophila melanogaster tissue to detect brain-specific differences in gene expression between the sexes and between two populations, one from the ancestral species range in sub-Saharan Africa and one from the recently colonized species range in Europe. Results Relatively few genes (Cyp6g1 and CHKov1. Conclusions Analysis of the brain transcriptome revealed many genes differing in expression between populations that were not detected in previous studies using whole flies. There was little evidence for sex-specific regulatory adaptation in the brain, as most expression differences between populations were observed in both males and females. The enrichment of genes with sexually dimorphic expression on the X chromosome is consistent with dosage compensation mechanisms affecting sex-biased expression in somatic tissues.

    To investigate the distribution of rubidium (Rb), cesium (Cs), beryllium (Be), strontium (Sr), and barium (Ba) in blood and urine in general Chinese population. A total of 18 120 subjects aged 6~60 years were enrolled from 24 regions in 8 provinces in Eastern, Central, and Western China from 2009 to 2010 based on the method of cluster random sampling. Questionnaire survey was conducted to collect the data on living environment and health status. Blood and urine samples were collected from these subjects, and the levels of Rb, Cs, Be, Sr, and Ba in these samples were determined by inductively coupled plasma mass spectrometry. The distribution of these elements in blood and urine in male or female subjects living in different regions was analyzed statistically. In the general Chinese population, the concentration of Be in the whole blood was below the detection limit (0.06 μg/L); the geometric mean (GM) of Ba in the whole blood was below the detection limit (0.45 μg/L), with the 95th percentile (P95)of 1.37 μg/L; the GMs (95% CI)of Rb, Cs, and Sr in the whole blood were 2 374(2 357~2 392) μg/L, 2.01 (1.98~2.05) μg/L, and 23.5 (23.3~23.7) μg/L, respectively; in males and females, the GMs (95%CI)of blood Rb, Cs, and Sr were 2 506 (2 478~2 533) μg/L and 2 248 (2 227~2 270) μg/L, 1.88 (1.83~1.94) μg/L and 2.16 (2.11~2.20) μg/L, and 23.4 (23.1~23.7) μg/L and 23.6 (23.3~23.9) μg/L, respectively(P0.05, and P>0.05). In the general Chinese population, the GM of urine Be was below the detection limit (0.06 μg/L), while the GMs (95%CI)of urine Rb, Cs, Sr, and Ba were 854 (836~873) μg/L, 3.65 (3.56~3.74) μg/L, 39.5 (38.4~40.6) μg/L, and 1.10 (1.07~1.12) μg/L, respectively; in males and females, the GMs (95%CI)of urine Rb, Cs, Sr, and Ba were 876 (849~904) μg/L and 832 (807~858) μg/L, 3.83 (3.70~3.96) μg/L and 3.47 (3.35~3.60) μg/L, 42.5 (40.9~44.2) μg/L and 36.6 (35.1~38.0) μg/L, and 1.15 (1.12~1.19) μg/L and 1.04 (1.01~1.07) μg/L, respectively (all P< 0

    The incidence of type 1 diabetes mellitus (T1DM) has increased in recent decades, as has the incidence of preterm births (prematurity and early prematurity (prematurity and birth season were compared with the general population birth registry using Pearson Chi-square test. The study population included 1452 T1DM patients, 52.7% males, and 2 138 668 subjects in the general non-T1DM population, 51.2% males. The prevalence of late and early prematurity was similar between groups (6.1% and 2.2% in the T1DM group vs 5.6% and 2.0% in the general non-T1DM group, P = 0.25 and P = 0.38, respectively). OR for prematurity among T1DM patients was 1.15 (0.95-1.39), P = 0.16. No difference in birth season was demonstrated between preterm and term, in T1DM and general non-T1DM populations. Ethiopian descent was more prevalent among T1DM patients compared with the non-T1DM population, in both term and preterm born. This is the largest population-based study, and the first in the Middle East geographical area, indicating that prematurity, including early prematurity, is not associated with T1DM during childhood.

    Acute care nurse practitioners, prepared as providers for a variety of populations of patients, continue to make substantial contributions to health care. Evidence indicates shorter stays, higher satisfaction among patients, increased work efficiency, and higher quality outcomes when acute care nurse practitioners are part of unit- or service-based provider teams. The Consensus Model for APRN Regulation: Licensure, Accreditation, Certification, and Education outlines detailed guidelines for matching nurse practitioners' education with certification and practice by using a population-focused algorithm. Despite national support for the model, nurse practitioners and employers continue to struggle with finding the right fit. Nurse practitioners often use their interest and previous nursing experience to apply for an available position, and hospitals may not understand preparation or regulations related to matching the appropriate provider to the work environment. Evidence and regulatory guidelines indicate appropriate providers for population-focused positions. This article presents history and recommendations for hiring acute care nurse practitioners as providers for different populations of patients. ©2015 American Association of Critical-Care Nurses.

    Full Text Available Susceptibility to insecticides was investigated by collecting field populations of brown planthopper from different locations of southern Karnataka, India (Gangavati, Kathalagere, Kollegala, Soraba and Mandya. All the field populations differed in their susceptibility to insecticides. In general, Soraba and Mandya populations were more susceptible to insecticides compared to Gangavati and Kathalagere populations. The resistance ratios varied greatly among the populations viz., chlorpyriphos (1.13- to 16.82-fold, imidacloprid (0.53- to 13.50-fold, acephate (1.34- to 5.32-fold, fipronil (1.13- to 4.06-fold, thiamethoxam (1.01- to 2.19-fold, clothianidin (1.92- to 4.86-fold, dinotefuran (0.82- to 2.22-fold, buprofezin (1.06- to 5.43-fold and carbofuran (0.41- to 2.17-fold. The populations from Gangavati, Kathalagere and Kollegala exhibited higher resistance to some of the old insecticides and low resistance to new molecules.

  10. Personality differences in two minnow populations that differ in their parasitism and predation risk

    2015-02-01

    Full Text Available Animals are often individually consistent in their behavior, not only over time, but also across different functional contexts. Recent research has focused on phenotypic and evolutionary mechanisms explaining such personality differences through selection. Parasitism and predation induce important mortality and fitness costs, and are thus the main candidates to create and maintain personality differences in the wild. Here, we present data on the behavioral consistency of the Eurasian minnow (Phoxinus phoxinus from two populations that live in different tributaries of the same river, but whose ecological environment differs fundamentally with regard to predation and parasitism. We experimentally demonstrate that minnow in both study populations are consistent in their boldness and activity. However, the two study populations differ notably: in the high predation and parasitism risk population fish show higher mean boldness, but tend to be less active than fish in low predation and parasitism risk population. Parasite (Diplostomum phoxini load was negatively, but not statistically significantly, associated with fish activity level. Our study suggests that parasitism and predation are likely important agents in the ecology and evolution of animal personalities.

  11. Trends in high-risk sexual behaviors among general population groups in China: a systematic review.

    2013-01-01

    The objective of this review was to investigate whether Chinese population groups that do not belong to classical high risk groups show an increasing trend of engaging in high-risk sexual behaviors. We systematically searched the English and Chinese literature on sexual risk behaviors published between January 1980 and March 2012 in PubMed and the China National Knowledge Infrastructure (CNKI). We included observational studies that focused on population groups other than commercial sex workers (CSWs) and their clients, and men who have sex with men (MSM) and quantitatively reported one of the following indicators of recent high-risk sexual behavior: premarital sex, commercial sex, multiple sex partners, condom use or sexually transmitted infections (STIs). We used generalized linear mixed model to examine the time trend in engaging in high-risk sexual behaviors. We included 174 observational studies involving 932,931 participants: 55 studies reported on floating populations, 73 on college students and 46 on other groups (i.e. out-of-school youth, rural residents, and subjects from gynecological or obstetric clinics and premarital check-up centers). From the generalized linear mixed model, no significant trends in engaging in high-risk sexual behaviors were identified in the three population groups. Sexual risk behaviors among certain general population groups have not increased substantially. These groups are therefore unlikely to incite a STI/HIV epidemic among the general Chinese population. Because the studied population groups are not necessarily representative of the general population, the outcomes found may not reflect those of the general population.

    2008-11-12

    Who should be screened for asymptomatic bacteriuria (AB) and who should be treated? This review updates some aspects of the management of AB in different patient populations. A systematic screening for AB is recommended for pregnant women because of a significant risk of complications. In these cases as well as before any uro-gynecologic surgical procedure treatment of AB is strongly recommended. The management of AB in immunosuppressed or transplanted patients is more controversial. In other populations treating AB is not recommended and the outcome seems to be worse in case of treatment due to possible side effects and selection of resistant organisms. Recent studies have shown a considerable gap between clinical practice and recommendations.

    2013-10-01

    Multivariable models for estimating cardiovascular disease (CVD) risk in people with diabetes comprise general population-based models and those from diabetic cohorts. Whether one set of models should receive preference is unclear. We evaluated the evidence on direct comparisons of the performance of general population vs diabetes-specific CVD risk models in people with diabetes. MEDLINE and EMBASE databases were searched up to March 2013. Two reviewers independently identified studies that compared the performance of general CVD models vs diabetes-specific ones in the same group of people with diabetes. Independent, dual data extraction on study design, risk models, outcomes; and measures of performance was conducted. Eleven articles reporting on 22 pair wise comparisons of a diabetes-specific model (UKPDS, ADVANCE and DCS risk models) to a general population model (three variants of the Framingham model, Prospective Cardiovascular Münster [PROCAM] score, CardioRisk Manager [CRM], Joint British Societies Coronary Risk Chart [JBSRC], Progetto Cuore algorithm and the CHD-Riskard algorithm) were eligible. Absolute differences in C-statistic of diabetes-specific vs general population-based models varied from -0.13 to 0.09. Comparisons for other performance measures were unusual. Outcomes definitions were congruent with those applied during model development. In 14 comparisons, the UKPDS, ADVANCE or DCS diabetes-specific models were superior to the general population CVD risk models. Authors reported better C-statistic for models they developed. The limited existing evidence suggests a possible discriminatory advantage of diabetes-specific over general population-based models for CVD risk stratification in diabetes. More robust head-to-head comparisons are needed to confirm this trend and strengthen recommendations. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    2008-01-01

    Screening of general populations with amino-terminal pro-B-type natriuretic peptides (NT-proBNP) holds promise for the detection of significant underlying cardiac structural and functional abnormalities, as well as for the early detection of the propensity to develop future cardiovascular events....... In comparative studies to date, NT-proBNP performs at least as well as BNP in the detection of heart disease and prognostication in the general population. In some studies and subgroups, NT-proBNP appears to outperform BNP in population screening. More needs to be learned about noncardiac sources of NT...

    2016-11-01

    Many of the world's most developed countries have adopted biomonitoring of toxic substances in order to ascertain their levels in biological samples. These substances get into the body through different environmental exposures. Monitoring toxic substances in biological samples should allow us to ascertain their levels in vulnerable groups, assess their evolution over time, make comparisons with levels observed in other countries, identify groups at risk or with high toxic levels and promote research. The main objective of biomonitoring is to act as a policy design tool to facilitate the implementation of particular measures in various sectors: health, environmental, agricultural and livestock or food industry sectors. In Spain, information on levels of toxic substances of environmental origin is provided by specific studies on health effects from environmental sources, such as the INMA project (INfancia y Medio Ambiente [childhood and environment]). In addition, biomonitoring projects have been implemented in Catalonia and the Canary Islands, together with a national biomonitoring programme in the adult working population. However, further progress is needed to develop a system that covers the general population as well as subgroups at risk, which relies on the collaboration of the involved authorities and the participation of professionals from different sectors and citizen organisations interested in the relationship between health and the environment.

    The study was conducted in a randomly selected sample of persons aged 15 years living in Ca Mau Province, southern Viet Nam. To estimate the prevalence of latent tuberculous infection (LTBI) in the general adult population of this province of Viet Nam. The secondary objective was to examine age and sex differences in prevalence. A cross-sectional survey was conducted in a cluster-random sample of the population. Clusters were subcommunes. The presence of LTBI was assessed using the QuantiFERON®-TB Gold In-Tube test system. QuantiFERON tests were performed among 1319 persons aged 15 years (77.7% of those selected). The overall prevalence of positive tests was 36.8% (95%CI 33.4-40.3). The prevalence of a positive test was lower in females than in males (31.0% vs. 44.7%, OR 0.57, 95%CI 0.45-0.72, P Viet Nam have evidence of LTBI. Although LTBI prevalence is higher in males, the sex difference is not as great as that for TB notification rates.

  1. Questioning the differences between general public vs. patient based preferences towards EQ-5D-5L defined hypothetical health states.

    2017-03-28

    The purpose of this article is to explore whether any differences exist between the general population and patient based preferences towards EQ-5D-5L defined hypothetical health states. The article discusses the role of adaptation and self-interest in valuing health states and it also contributes rigorous empirical evidence to the scientific debate on the differences between the patient and general population preferences towards hypothetical health states. Patient preferences were elicited in 2015 with the EQ-5D-5L questionnaire using time trade-off and discrete choice experiment design and compared to the Spanish general population preferences, which were elicited using identical methods. Patients were chosen on a voluntary basis according to their willingness to participate in the survey. They were recruited from patient organisations and a hospital in Madrid, Spain. 282 metastatic breast cancer patients and 333 rheumatoid arthritis patients were included in the sample. The analysis revealed differences in preferences between the general population and patient groups. Based on the results of our analysis, it is suggested that the differences in preferences stem from patients being more able to accurately imagine "non-tangible" dimensions of health states (anxiety or depression, and pain or discomfort) than the general population with less experience in various health states. However, this does not mean that general public values should not be reflected in utilities derived for coverage decision making. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Estimation of general and specific combining ability effects in a diallel analysis of cross-pollinating populations, including the selfed parents, is presented in this work. The restrictions considered satisfy the parametric values of the GCA and SCA effects. The method is extended to self-pollinating populations (suitable for other species, without the selfed parents. The analysis of changes in population means due to inbreeding (sensitivity to inbreeding also permits to assess the predominant direction of dominance deviations and the relative genetic variability in each parent population. The methodology was used to select popcorn populations for intra- and inter-population breeding programs and for hybrid production, developed at the Federal University of Viçosa, MG, Brazil. Two yellow pearl grain popcorn populations were selected.

    2016-12-01

    Participation in occupations is a basic human right. Although people with schizophrenia commonly experience restrictions in participation, there is a paucity of research in this area. This study aimed to compare the participation patterns of people with schizophrenia to people without mental illness (control group). A total of 140 people of similar age and sex completed the Adults Subjective Assessment of Participation and provided demographic and health-related data. People with schizophrenia tend to participate in fewer activities and to participate alone. However, they participate with similar intensity as those in the control group. The participation patterns of people with schizophrenia are both unique and similar to those of the general population. The differences in participation raise concerns due to signs of restriction and social exclusion. However, it appears that people with schizophrenia benefit from occupation and community-based services that promote and support participation with others in diverse activities.

    To evaluate and describe the pupil ruff changes and relationship to intraocular pressure, pseudoexfoliation syndrome and glaucoma status in an optometric population in New Zealand. Prospective cross-sectional survey of an optometric population. Six hundred and twenty subjects over 50 years old routinely attending the participating optometry practices. Exclusion criteria included previous intraocular surgery, ophthalmic laser, uveitis, angle closure and secondary glaucoma. Multicentre study involving 11 optometry practices in the Wellington region, New Zealand. The pupillary ruff and associated gonioscopy findings of study participants were graded based on the previously published Pupil Ruff Atrophy grading system. Parameters evaluated include pupillary ruff absence and abnormality, pseudoexfoliation material and trabecular meshwork pigmentation. Correlations between intereye Pupil Ruff Atrophy grading differences and inter-eye intraocular pressure and cup:disc ratio differences. Six hundred and twenty subjects were included, with a mean age of 62.2 ± 9.1 years and mean intraocular pressure of 14.8 ± 3.4 mmHg. Four hundred and fourteen (66.8%) had bilateral pupil ruff changes and 12 (1.5%) had pseudoexfoliation. Inter-eye intraocular pressure asymmetry was significantly correlated with amount of missing pupillary ruff (r = 0.111; P = 0.022) and trabecular meshwork pigmentation (r = 0.147; P = 0.002). Inter-eye cup:disc ratio asymmetry was not correlated with any of the Pupil Ruff Atrophy grading parameters. Asymmetry of pupillary ruff absence and trabecular meshwork pigmentation was correlated with intraocular pressure asymmetry (but not with cup:disc ratio asymmetry) in a general optometric population setting in New Zealand. © 2012 The Authors.

    The aim of this study is two-fold. The first part compares quality of life (QoL) data of prostate cancer patients with those of a representative and age-specific sample of the general population and analyzes the influence of cancer related as well as socio-demographic parameters on QoL. Secondly, differences in QoL depending on the experienced psychological distress will be shown both in prostate cancer patients and in the general population. A sample of 265 prostate cancer patients completed both the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and the Hospital Anxiety and Depression Scale (HADS) during their stay in the hospital. A total HADS cut off score of 15 was used to indicate psychological distress and significant emotional concerns in patients and men of the general population. The results of the patients were compared with those of the general population (N=444). Prostate cancer patients reported significantly worse levels of social and emotional functioning as well as more symptoms like insomnia, constipation and diarrhea compared to the general population. Patients and men of the general population with a total HADS score >/=15 reported lower QoL in all sub-scales except for diarrhea in comparison to people without distress. Psychological distress is accompanied by lower QoL and therefore should be taken into consideration when QoL is assessed. Furthermore, clinicians should be trained by professionals to detect distress in their patients and to pay more attention to their emotional concerns, which are strongly associated with the patients' well-being and QoL during their stay in hospital.

    2015-11-17

    Regional differences in physician supply can be found in many health care systems, regardless of their organizational and financial structure. A theoretical model is developed for the physicians' decision on office allocation, covering demand-side factors and a consumption time function. To test the propositions following the theoretical model, generalized linear models were estimated to explain differences in 412 German districts. Various factors found in the literature were included to control for physicians' regional preferences. Evidence in favor of the first three propositions of the theoretical model could be found. Specialists show a stronger association to higher populated districts than GPs. Although indicators for regional preferences are significantly correlated with physician density, their coefficients are not as high as population density. If regional disparities should be addressed by political actions, the focus should be to counteract those parameters representing physicians' preferences in over- and undersupplied regions.

    Full Text Available The study aims to investigate sleep duration in four different population groups in a national probability sample of older South Africans who participated in the Study of Global Ageing and Adult Health (SAGE Wave 1. A national population-based cross-sectional study with a sample of 3284 aged 50 years or older in South Africa was conducted in 2008. The questionnaire included socio-demographic characteristics, health variables, and self-reported sleep duration. Results indicate that White Africans compared to other population groups had the lowest mean sleep duration (7.88 h among men and 7.46 h among women. The prevalence of short sleep was the highest among both men and women among the White African (18.8% in men and 16.9% in women and Indian or Asian African population groups (14.5% in men and 17.1% in women, and lowest among both men and women in the Black African (7.0% in men and 6.5% in women and multi-ancestry population groups (15.6% in men and 12.7% in women. The prevalence of long sleep was among both men and women the highest in the Black African population group (56.2% in men and 58.5% in women, and the lowest in the White African population group (36.4% in men and 24.3% in women. In a Poisson regression model, adjusted for sociodemographics and chronic disease status, coming from the male and female White African population group was associated with short sleep. In addition, coming from the Indian or Asian African population group was associated with short sleep. No population group differences were found regarding long sleep prevalence. White Africans reported more short sleep duration than the other population groups, while there were no racial or ethnic differences in long sleep. White Africans are more likely to have sleep durations that are associated with negative health outcomes. An explanation of the high short sleep prevalence among White Africans may be related to their racial or ethnic minority status in South Africa.

    To define different populations of renal interstitial cells and investigate some aspects of their function, we studied the kidneys of normal rats and rats with hereditary diabetes insipidus (DI, Brattleboro) after experimental manipulations expected to alter the number of interstitial cells. DI rats showed an almost complete loss of interstitial cells in their renal papillae after treatment with a high dose of vasopressin. In spite of the lack of interstitial cells, the animals concentrated their urine to the same extent as vasopressin-treated normal rats, indicating that the renomedullary interstitial cells do not have an important function in concentrating the urine. The interstitial cells returned nearly to normal within 1 week off vasopressin treatment, suggesting a rapid turnover rate of these cells. To further distinguish different populations of interstitial cells, we studied the distribution of class II MHC antigen expression in the kidneys of normal and bone-marrow depleted Wistar rats. Normal rats had abundant class II antigen-positive interstitial cells in the renal cortex and outer medulla, but not in the inner medulla (papilla). Six days after 1000 rad whole body irradiation, the stainable cells were almost completely lost, but electron microscopic morphometry showed a virtually unchanged volume density of interstitial cells in the cortex and outer medulla, as well as the inner medulla. Thus, irradiation abolished the expression of the class II antigen but caused no significant depletion of interstitial cells

    Full Text Available The aim of this study is to investigate the association between personal values and self-esteem in general population and clinical population. The sample was composed of a group of patients with a diagnosis of anxiety disorders and/or depression (n = 60 and a comparison group, paired by sex and age, of general population (n = 60. The Portrait Values Questionnaire of Schwartz (PVQ and the Autoe Self-esteem Scale were used. T-tests were performed to compare the scores of both instruments between the two groups. The clinical sample scored significantly lower in Self-esteem, Self- direction, Hedonism, and Openness to Change. For this reason, Pearson correlations were calculated in differential groups (clinical and general between the PVQ and the Self-esteem Scale. In the general population group self-esteem was associated to one value: Self-direction. In the clinical group, self-esteem was associated mainly to Self- direction, but also to Hedonism, Power and Security; and to the axis Self-promotion and Openness to Change. Both in the clinical and general population samples it was found a significant association between the interest in having independent thought, freedom of action and exploring with higher levels of self-esteem.

    Adversity early in life has been suggested as a protective factor for elderly suicides. However, studies examining this relationship in general population suicide rates are scarce. The relationship between general population suicide rates and four proxy measures of adversity earlier in life was examined using data from the World Health Organization and the United Nations data banks. General population suicide rates were negatively correlated with the percentage of children under the age of 5 years who were underweight, the percentage of children under the age of 5 years who were under height, the percentage of infants with low birth weight babies, and the percentage of the general population that was undernourished. The only independent predictor general population suicide rates in both sexes, on multiple regression analysis, was the Gini coefficient (a measure of income inequality). Income inequality may lead to low birth weight, undernourishment, underweight and under height because income inequality results in poor access to healthcare and nutrition. These adversities may increase child mortality rates and reduce life expectancy. Those surviving into adulthood in countries with greater adversity early in life may be at reduced risk of suicide because of selective survival of those at reduced risk of suicide due to constitutional or genetic factors and development of greater tolerance to hardship in adulthood. ‎

    Women make up about 14 percent of general dentists in the United States, and the proportion is projected to exceed 29 percent by 2020. The authors obtained dental benefits claims data from the Washington Dental Service (WDS), Seattle, and used them to examine the practice patterns of 265 women and 1,947 men engaged in general dentistry for at least 26 days in 2001. Practice variables of interest included age, days worked, procedures performed and total income from WDS reimbursements and patient copayments. The number, age and sex of patients treated also were obtained. Using productivity data, the authors also estimated the potential impact of an increase in the percentage of female dentists in the state. The authors found no differences between male and female dentists in the number of procedures per patient, income per patient or income per day of work. Frequency distributions of various services were highly similar for both groups. Multiple regression models showed no influence of dentist's sex on total income. However, the mean and median numbers of days worked were about 10 percent lower for female dentists than for male dentists. This difference was consistent with the finding that female dentists treated approximately 10 percent fewer patients, performed about 10 percent fewer procedures and had a combined income of about 10 percent less than that of male dentists. Practice patterns of male and female dentists generally were equivalent in this WDS population. Female and male dentists provided a similar range of services and earned an equal income per patient treated and per day worked. However, women worked fewer days per year than did men, irrespective of age. If the dental work force and practice patterns remain unchanged otherwise, the total number of patients treated per dentist will decrease slightly as women make up an increasing proportion of dentists.

  19. A General Framework for Setting Quantitative Population Objectives for Wildlife Conservation

    Full Text Available https://doi.org/10.15447/sfews.2017v15iss1art8Quantitative population objectives are necessary to successfully achieve conservation goals of secure or robust wildlife populations. However, existing methods for setting quantitative population objectives commonly require extensive species-specific population viability data, which are often unavailable or are based on estimates of historical population sizes, which may no longer represent feasible objectives. Conservation practitioners require an alternative, science-based method for setting long-term quantitative population objectives. We reviewed conservation biology literature to develop a general conceptual framework that represents conservation biology principles and identifies key milestones a population would be expected to pass in the process of becoming a recovered or robust population. We then synthesized recent research to propose general hypotheses for the orders of magnitude at which most populations would be expected to reach each milestone. The framework is structured as a hierarchy of four population sizes, ranging from very small populations at increased risk of inbreeding depression and extirpation (< 1,000 adults to large populations with minimized risk of extirpation (> 50,000 adults, along with additional modifiers describing steeply declining and resilient populations. We also discuss the temporal and geographic scales at which this framework should be applied. To illustrate the application of this framework to conservation planning, we outline our use of the framework to set long-term population objectives for a multi-species regional conservation plan, and discuss additional considerations in applying this framework to other systems. This general framework provides a transparent, science-based method by which conservation practitioners and stakeholders can agree on long-term population objectives of an appropriate magnitude, particularly when the alternative approaches are

    Simulations are a key tool in molecular ecology for inference and forecasting, as well as for evaluating new methods. Due to growing computational power and a diversity of software with different capabilities, simulations are becoming increasingly powerful and useful. However, the widespread use of simulations by geneticists and ecologists is hindered by difficulties in understanding these softwares’ complex capabilities, composing code and input files, a daunting bioinformatics barrier, and a steep conceptual learning curve. skeleSim (an R package) guides users in choosing appropriate simulations, setting parameters, calculating genetic summary statistics, and organizing data output, in a reproducible pipeline within the R environment. skeleSim is designed to be an extensible framework that can ‘wrap’ around any simulation software (inside or outside the R environment) and be extended to calculate and graph any genetic summary statistics. Currently, skeleSim implements coalescent and forward-time models available in the fastsimcoal2 and rmetasim simulation engines to produce null distributions for multiple population genetic statistics and marker types, under a variety of demographic conditions. skeleSim is intended to make simulations easier while still allowing full model complexity to ensure that simulations play a fundamental role in molecular ecology investigations. skeleSim can also serve as a teaching tool: demonstrating the outcomes of stochastic population genetic processes; teaching general concepts of simulations; and providing an introduction to the R environment with a user-friendly graphical user interface (using shiny).

    To understand the current status of iodine nutrition among the community residents to compare the level of iodine nutrition in different areas and groups of populations in Zhejiang province. Stratified cluster sampling method was adopted and residents from twenty-two communities in Zhejiang province were selected. A cross-sectional survey was conducted, using questionnaires, laboratory tests, on urinary iodine, water iodine and the concentration of the iodine in salt, which had played positive roles in the calculation of the level of iodine nutrition. of the iodine nutrition in this cross-sectional survey were as follows: the median water iodine and salt iodine of Zhejiang were 2.42 µg/L and 28.8 mg/kg, respectively. The coverage of iodized salts was 79.54%, with the ingesting rate of qualified iodized-salt as 76.65% and the median content of urinary iodine in the population of Zhejiang was 161 µg/L. The average iodine content among pregnant women was 138 µg/L, with the percentage of samples less than 100 µg/L as 25.92%, more than 300 µg/L as 15.30%. The proportions of iodine intake through water, salt and other foods were 1.70%, 76.41% and 21.89%, respectively. The status of iodine nutrition in Zhejiang province in general seemed to be appropriate, but the level of iodine nutrition in pregnant women was less than the requirement, which should call for attention.

    Full Text Available INTRODUCTION: Literature suggests that good quality health care access can have a positive impact on the health of people with serious mental illness (SMI, but literature relating to patterns of access by this group is equivocal. AIM: This study was designed to explore health care access patterns in a group of people with SMI and to compare them with a general New Zealand population group, in order for health providers to understand how they might contribute to positive health outcomes for this group. METHODS: The study surveyed 404 mental health consumers aged 18-65 years receiving care from one district health board in Auckland about their patterns of health care access. Results were compared with those from the New Zealand Health Survey of the general population. RESULTS: Findings suggest that the SMI consumer respondents had poorer physical health than the general population respondents, accessed health care services in more complex ways and were more particular about who they accessed for their care than the general population respondents. There was some concern from SMI consumers around discrimination from health care providers. The study also suggested that some proactive management with SMI consumers for conditions such as metabolic syndrome was occurring within the health care community. DISCUSSION: The first point of access for SMI consumers with general health problems is not always the family general practitioner and so other health professionals may sometimes need to consider the mental and physical health of such consumers in a wider context than their own specialism.

    Background: To evaluate the prevalence and characteristics of paratracheal air cysts and their association with emphysema and gender in a general population using low-dose computed tomography scanning of the chest. Materials and methods: We retrospectively enrolled a total of 924 patients (584 women, 340 men; mean age, 59.73 years; range, 37–89 years) who had received low-dose computed tomography scanning for health examination during the period January 1, 2010 to June 30, 2010. Computed tomographic images were evaluated for the presence of paratracheal air cysts. If paratracheal air cysts were identified, the lungs were reconstructed as a three-dimensional model on a commercial workstation. An emphysema index, an objective quantification of the extent of emphysematous changes on CT imaging, was defined as the percentage area of lung with attenuation values below −950 Hounsfield units. Results: A total of 60 patients with paratracheal air cysts were included in this study (estimated prevalence, 6.5%; 12 men, 48 women; mean age, 59.85; range 45–89 years). Emphysema index differed significantly between genders (P < 0.0001). The prevalence of paratracheal air cysts in men was significantly lower than that in women (P = 0.005); however, the emphysema index in patients of both genders showed no evidence of emphysema. The majority (95%) of paratracheal air cysts were at the level of the seventh cervical to the second thoracic vertebrae. Conclusion: The presence of paratracheal air cysts is a common condition in general populations and should not be misdiagnosed as abnormal paratracheal free air. Paratracheal air cysts are more common in woman than in man. In our study, there is no patient with paratracheal air cysts has CT evidence of emphysema.

    The current study evaluates the reliability and factor-structure replicability of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire (TEMPS-A) in its Greek Version. The TEMPS-A was administered to a convenient sample of 734 subjects from the general Greek population (436 females; 59.4% and 298 males; 40.6%). Their mean age was 40.80±11.48 years (range 25-67 years). The analysis included the calculation of Chronbach's alpha, the calculation of the threshold to define dominant temperaments (+2 standard deviations or 95th percentile), confirmatory factor analysis and the calculation of Pearson correlation coefficients between the temperament scales scores. Analysis of Covariance with age as covariate and post-hoc t-test was used to search for differences in temperament scores between males and females. Also a table of percentile values corresponding to a raw score was created. Internal consistency was excellent for the various temperaments (0.72-0.88). The factor analysis confirmed the five factor solution as the best factor solution. All TEMPS items were included in the final version of the scale in the Greek language. The study sample included subjects from the general population, but it is a convenient and not representative sample. Although the authors tried to select them on the basis of being mentally healthy and without a psychiatric history, there is always a degree of uncertainty. There is also always the possibility some of them to manifest a mental disorder in the future, thus being currently in a premorbid state. The Greek version of the TEMPS-A, has good internal consistency and factor structure similar to what was found in other translations. Overall our results are in accord with the literature and in line with theoretical considerations as well as with empirical evidence. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Physicians in Taiwan have a heavy workload and a stressful workplace, both of which may contribute to cardiovascular disease. However, the risk of acute myocardial infarction (AMI in physicians is not clear. This population-based cohort study used Taiwan’s National Health Insurance Research Database. We identified 28,062 physicians as the case group and randomly selected 84,186 nonmedical staff patients as the control group. We used a conditional logistic regression to compare the AMI risk between physicians and controls. Subgroup analyses of physician specialty, age, gender, comorbidities, area, and hospital level were also done. Physicians have a higher prevalence of HTN (23.59% versus 19.06%, P<0.0001 and hyperlipidemia (21.36% versus 12.93%, P<0.0001 but a lower risk of AMI than did the controls (adjusted odds ratio (AOR: 0.57; 95% confidence interval (CI: 0.46–0.72 after adjusting for DM, HTN, hyperlipidemia, and area. Between medical specialty, age, and area subgroups, differences in the risk for having an AMI were nonsignificant. Medical center physicians had a lower risk (AOR: 0.42; 95% CI: 0.20–0.85 than did local clinic physicians. Taiwan’s physicians had higher prevalences of HTN and hyperlipidemia, but a lower risk of AMI than did the general population. Medical center physicians had a lower risk than did local clinic physicians. Physicians are not necessary healthier than the general public, but physicians, especially in medical centers, have a greater awareness of disease and greater access to medical care, which permits timely treatment and may prevent critical conditions such as AMI induced by delayed treatment.

    Full Text Available Abstract    BACKGROUND: Enhancement of albumin exertion in urine increases the risk of renal and ischemic heart diseases (IHD. We assessed the association of urine albumin and sub-clinical IHD in a random sample of Iranian general population.    METHODS: The random sample in general population in Isfahan County was recruited to the cross-sectional study. From the all sample blood pressure and lipid profile were assessed and morning urine spot was measured for albumin and Creatinine. Microalbuminuria was defined either Albumin-Creatinine Ratio (ACR was 30-300mg. Also, the standard 12 lead electrocardiogram (ECG was carried out for all participants. The ECG pattern was divided to two categories; normal or ECG with ischemia. The logistic regression model was determined the odds of albuminuria for ischemic changes in ECG.    RESULTS: 999 subjects, age 35-70 years, participated to study. From all, 40.8% were male. Microalbuminuria was detected in 8% and sub-clinical ECG ischemic changes were found in 23.4%. The most frequent ischemic change was T wave inversion. The mean urine albumin levels in subjects with normal ECG was 9.6±14.6 mg/ml and in ischemic group was 8.5±12.2 mg/ml and they did not have statistically different. The odds ratios of neither Albumin-Creatinine ratio nor microalbuminuria were in significant range for risk to ischemic changes in ECG of apparently healthy participants. They was consecutively OR=0.9 (0.51-1.6, OR=0.99 (0.98-1.004.     CONCLUSION: Our finding didn’t declare any association between ACR and IHD. Because of showing this association in the other study; it needs more exploration regarding to association between microalbuminuria and cardiovascular diseases incidence.      Keywords: Ischemic heart diseases, electrocardiogram, Albumin-Creatinine Ratio, Urine Albumin

    Higher education is associated with substantial adult life benefits, including higher income and improved quality of life, among others. The current study compared adult outcomes of 250 foster care alumni college graduates with two samples of general population graduates to explore the role higher education plays in these young adults' lives. Outcomes compared include employment, income, housing, public assistance, physical and mental health, happiness, and other outcomes that are often found to be related to educational attainment. Foster care alumni college graduates were very similar to general population college graduates for individual income and rate of employment. However, foster care alumni graduates were behind general population graduates on factors such as self-reported job security, household earnings, health, mental health, financial satisfaction, home ownership, happiness, and public assistance usage. Results have implications for policy and practice regarding the most effective means of supporting postcollege stability of youths with foster care experience.

    The purpose of this study was to review the rate of adverse events after contrast medium administration in the general population and at-risk patients (renal impairment, heart failure (NYHA III or IV), hypotension or hypertension, coronary artery disease, previous reaction to contrast media, asthma and/or allergies, dehydration, diabetes mellitus, poor general condition) under daily practice conditions in a post-marketing surveillance study. Two hundred and ten radiologists conducted various X-ray examinations in 52,057 patients. To document the safety of iobitridol in routine use, all patients undergoing X-ray examinations were included. Exclusion criteria were contraindications listed in the locally approved summary of product characteristics. The adverse event rate was 0.96% (at-risk patients 1.39%); the rate of serious adverse events 0.044% in all patients (at-risk patients 0.057%). Adverse events occurred more often in women than in men (P<0.001). In patients who had previously reacted to a contrast medium, adverse events were reported in 3.43% with mild to moderate symptoms. In 47.76% of these patients, a premedication was administered. There was no difference in the frequency of adverse events and serious adverse events whether premedicated or not (P=0.311 and P=0.295, respectively). Iobitridol was well-tolerated in 99.04% of cases (at-risk patients 98.61%). (orig.)

    In animals, exposure to certain phthalates negatively affects the male reproductive function. Human results are conflicting and mostly based on subfertile males, in whom the association between exposure and reproductive function may differ from the general population. To study if levels of phthalate metabolites were associated with semen quality and reproductive hormones in general Swedish men. We recruited 314 young men delivering semen, urine and blood samples at the same visit. We analyzed reproductive hormones and several semen parameters including progressive motility and high DNA stainability (HDS)-a marker for sperm immaturity. In urine, we analyzed metabolites of phthalates, including diethylhexyl phthalate (DEHP). We studied associations between urinary levels of the metabolites and seminal as well as serum reproductive parameters, accounting for potential confounders. DEHP metabolite levels, particularly urinary mono-(2-ethyl-5-carboxypentyl) phthalate (MECPP), were negatively associated with progressive sperm motility, which was 11 (95% CI: 5.0-17) percentage points lower in the highest quartile of MECPP than in the lowest. Further, men in the highest quartile of the DEHP metabolite monoethylhexyl phthalate had 27% (95% CI: 5.5%-53%) higher HDS than men in the lowest quartile. DEHP metabolite levels seemed negatively associated with sperm motility and maturation. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background Previous researches aiming to estimate the association between metabolic syndrome and depressive symptoms come out with inconsistent results. Besides, most of them are conducted in the developed areas. There is lack of the data from rural China. The aim of this study is to confirm whether gender difference exists among the relationship between MetS, metabolic components and depressive symptoms in the rural Chinese population. Methods A cross-sectional analysis enrolled 11430 subjects’ aged ≥35 from rural Northeast China. Metabolic and anthropometric indicators were measured according to standard methods. Depressive symptoms were defined using the Patient Health Questionnaire-9 (PHQ-9. Results The prevalence of depressive symptoms was 6% among rural Northeast general population and the prevalence of MetS and its components were 39.0% for MetS, 42.9% for abdominal obesity, 67.1% for elevated blood pressure, 47.1% for hyperglycemia, 32.1% for hypertriglyceridemia, 29.5% for low HDL-C. Depressive symptoms were associated with triglyceride component (OR = 1.24, 95%CI: 1.05–1.46, P = 0.01 but not MetS (OR = 1.11, 95%CI: 0.94–1.30, P = 0.23. Moreover, depressive symptoms were associated with triglyceride component (OR = 1.21, 95% CI = 1.00–1.47, P = 0.05 in women only. But once adjusted for menopause status, depressive symptoms were no longer statically associated with triglyceride component (OR = 1.20, 95% CI = 0.99–1.46, P = 0.07. Conclusions Depressive symptoms were associated with triglyceride component but not MetS in rural Chinese population. Routine lipid screening should be recommended among rural depressed residents especially among female.

    Some previous studies have proposed potential explanatory factors for the social gradient in sickness absence. Yet, this research area is still in its infancy and in order to comprise the full range of socioeconomic positions there is a need for studies conducted on random population samples. The main aim of the present study was to investigate if somatic and mental symptoms, mental wellbeing, job strain, and physical work environment could explain the association between low socioeconomic position and belonging to a sample of new cases of sick-listed employees. This study was conducted on one random working population sample (n = 2763) and one sample of newly sick-listed cases of employees (n = 3044), drawn from the same random general population in western Sweden. Explanatory factors were self-rated 'Somatic and mental symptoms', 'Mental well-being', 'job strain', and 'physical work conditions' (i.e. heavy lifting and awkward work postures). Multiple logistic regression analyses were used. Somatic and mental symptoms, mental well-being, and job strain, could not explain the association between socioeconomic position and sickness absence in both women and men. However, physical work conditions explained the total association in women and much of this association in men. In men the gradient between Non-skilled manual OR 1.76 (1.24;2.48) and Skilled manual OR 1.59 (1.10;2.20), both in relation to Higher non-manual, remained unexplained. The present study strengthens the scientific evidence that social differences in physical work conditions seem to comprise a key element of the social gradient in sickness absence, particularly in women. Future studies should try to identify further predictors for this gradient in men.

    To describe contraceptive use among U.S. female family planning providers and to compare their contraceptive choices to the general population. We surveyed a convenience sample of female family planning providers ages 25-44 years, including physicians and advanced practice clinicians, via an internet-based survey from April to May 2013. Family planning providers were compared to female respondents ages 25-44 years from the 2011-2013 National Survey of Family Growth. A total of 488 responses were eligible for analysis; 331 respondents (67.8%) were using a contraceptive method. Providers' contraceptive use differed markedly from that of the general population, with providers significantly more likely to use intrauterine contraception, an implant, and the vaginal ring. Providers were significantly less likely to use female sterilization and condoms. There were no significant differences between providers and the general population in use of partner vasectomy or the pill. Long-acting reversible contraception (LARC) use was significantly higher among providers than in the general population (41.7% vs. 12.1%, pfamily planning providers differed significantly from the general population. These findings have implications for clinical practice, patient education, and health policy. Family planning providers report higher use of LARC than the general population. This may reflect differences in preferences and access. Providers might consider sharing these findings with patients, while maintaining patient choice and autonomy. Copyright © 2015 Elsevier Inc.

    Subclinical psychotic symptoms are associated to negative life outcomes in the general population, but their relationship with cognitive performance is still not well understood. Assessing the relationship between performance in cognitive domains and subclinical psychotic symptoms in the general population may also help understand the handicap attributed to clinical psychosis, in which these alterations are present. Subclinical and cognitive assessments were obtained in 203 participants from the general population by means of the Community Assessment of Psychic Experiences, the Brief Assessment of Cognition in Schizophrenia, the Wechsler Adults Intelligence Scale and the Wisconsin Card Sorting Test. The positive and negative subclinical symptoms and their relationship with age and cognition were examined, followed by assessing the influence of subclinical depression scores on the possible relationships between those subclinical psychotic symptoms and cognitive deficits. Inverse relationships were found between frequency in the Community Assessment of Psychic Experiences positive dimension and motor speed, and frequency and distress in the Community Assessment of Psychic Experiences negative dimension and motor speed. A direct relationship was also found between distress scores of the positive dimension and executive functions. Both positive and negative subclinical symptoms were related to depression scores. Psychotic symptoms, similar to those in the clinical population, may be associated with cognitive deficits in the general population. Copyright © 2015 SEP y SEPB. Published by Elsevier España.

    Variants in HNF1A encoding hepatocyte nuclear factor 1α (HNF-1A) are associated with maturity-onset diabetes of the young form 3 (MODY 3) and type 2 diabetes. We investigated whether functional classification of HNF1A rare coding variants can inform models of diabetes risk prediction in the general population by analyzing the effect of 27 HNF1A variants identified in well-phenotyped populations (n = 4,115). Bioinformatics tools classified 11 variants as likely pathogenic and showed no association with diabetes risk (combined minor allele frequency [MAF] 0.22%; odds ratio [OR] 2.02; 95% CI 0.73–5.60; P = 0.18). However, a different set of 11 variants that reduced HNF-1A transcriptional activity to diabetes in the general population (combined MAF 0.22%; OR 5.04; 95% CI 1.99–12.80; P = 0.0007). Our functional investigations indicate that 0.44% of the population carry HNF1A variants that result in a substantially increased risk for developing diabetes. These results suggest that functional characterization of variants within MODY genes may overcome the limitations of bioinformatics tools for the purposes of presymptomatic diabetes risk prediction in the general population.

    The flavour perceived by humans when eating varies depending on age, gender, habits, emotional status, etc. The present study reflects the changes in the perception of sweet and salt flavours among different population groups depending on age, with an assessment, for each flavour, of the threshold concentration for the detection of these flavours. Triangular discrimination sensorial tests were performed in three groups, with thirty members in each, classified to represent young, adult and elderly age groups. With regard to sweet flavours, the groups of young people and adults distinguished the different sample at 0.1% of sugar for 95% and 99% significance levels, whereas the elderly required the concentration to reach 1% at both levels before they could distinguish the sugar solution from water. In the case of salt flavours, young people are able to detect the different sample at the lowest concentration level, for both levels of significance. Adults significantly distinguished the sample containing 0.05% of salt, at the 95% significance level, whereas the elderly needed a concentration of 0.1% for both levels of significance. Age-dependent variations in response were observed. As age increases, greater concentrations are required in order to distinguish the salt or sweet solutions from the samples containing only water.

  7. Population spikes in cortical networks during different functional states.

    Full Text Available Brain computational challenges vary between behavioral states. Engaged animals react according to incoming sensory information, while in relaxed and sleeping states consolidation of the learned information is believed to take place. Different states are characterized by different forms of cortical activity. We study a possible neuronal mechanism for generating these diverse dynamics and suggest their possible functional significance. Previous studies demonstrated that brief synchronized increase in a neural firing (Population Spikes can be generated in homogenous recurrent neural networks with short-term synaptic depression. Here we consider more realistic networks with clustered architecture. We show that the level of synchronization in neural activity can be controlled smoothly by network parameters. The network shifts from asynchronous activity to a regime in which clusters synchronized separately, then, the synchronization between the clusters increases gradually to fully synchronized state. We examine the effects of different synchrony levels on the transmission of information by the network. We find that the regime of intermediate synchronization is preferential for the flow of information between sparsely connected areas. Based on these results, we suggest that the regime of intermediate synchronization corresponds to engaged behavioral state of the animal, while global synchronization is exhibited during relaxed and sleeping states.

    A number of studies have shown an association between male pattern baldness (MPB) and cardiovascular disease. Few of these studies, however, have examined whether MPB is a novel risk factor, or is associated with abnormalities of established coronary risk factors. We have therefore performed an analysis of MPB and cardiovascular risk factors in the general population. A total of 1219 male participants aged 18-70 years from the Victorian Family Heart Study were surveyed using a validated questionnaire for degree and pattern of baldness. Carefully standardized measures of height, weight, blood pressure, pulse rate, total and high-density lipoprotein cholesterol, and plasma fibrinogen were made. Subjects were grouped according to the degree and pattern of baldness as: no baldness, frontal baldness and vertex baldness. Bald men were older than non-bald men (P < 0.0001). Age was also associated with increased levels of coronary risk factors (P < 0.0001). When multiple regression was used to adjust for age differences, the levels of coronary risk factors were not significantly different between the bald and non-bald groups. The lack of association between baldness and established coronary risk factors implies that baldness may predispose to coronary heart disease through novel mechanisms yet to be defined.

    Studies of the relationship between bullying and suicide behavior yield mixed results. This is the first study comparing frequencies of suicide behavior in four bullying groups (bully, victim, bully/victim, and neither) in two large psychiatric and community samples of young children and adolescents. Maternal ratings of bullying and suicide ideation and attempts were analyzed for 1,291 children with psychiatric disorders and 658 children in the general population 6-18 years old. For both the psychiatric and community samples, suicide ideation and attempt scores for bully/victims were significantly higher than for victims only and for neither bullies nor victims. Differences between victims only and neither victims nor bullies were nonsignificant. Controlling for sadness and conduct problems, suicide behavior did not differ between the four bullying groups. All children with suicide attempts had a comorbid psychiatric disorder, as did all but two children with suicide ideation. Although the contribution of bullying per se to suicide behavior independent of sadness and conduct problems is small, bullying has obvious negative psychological consequences that make intervention imperative. Interventions need to focus on the psychopathology associated with being a victim and/or perpetrator of bullying in order to reduce suicide behavior.

    Full Text Available Literature suggests that the effect of winter birth on vulnerability to schizophrenia might be mediated by increased expression of proinflammatory cytokines due to prenatal infection and its inadequate regulation by anti-inflammatory factors. As the response of the immune system depends on genotype, this study assessed the interaction effects of cytokine genes and season of birth (SOB on schizotypy measured with the Schizotypal Personality Questionnaire (SPQ-74. We searched for associations of IL1B rs16944, IL4 rs2243250, and IL-1RN VNTR polymorphisms, SOB, and their interactions with the SPQ-74 total score in a sample of 278 healthy individuals. A significant effect of the IL4 X SOB interaction was found, p=0.007 and η2=0.028. We confirmed this effect using an extended sample of 373 individuals. Homozygotes CC born in winter showed the highest SPQ total score and differed significantly from winter-born T allele carriers, p=0.049. This difference was demonstrated for cognitive-perceptual and disorganized but not interpersonal dimensions. The findings are consistent with the hypothesis that the cytokine genes by SOB interaction can influence variability of schizotypal traits in the general population. The IL4 T allele appeared to have a protective effect against the development of positive and disorganized schizotypal traits in winter-born individuals.

    Full Text Available BACKGROUND: Little is known about the relation of different dietary protein types with blood pressure (BP. We examined whether intake of total, plant, animal, dairy, meat, and grain protein was related to BP in a cross sectional cohort of 20,820 Dutch adults, aged 20-65 y and not using antihypertensive medication. DESIGN: Mean BP levels were calculated in quintiles of energy-adjusted protein with adjustment for age, sex, BMI, education, smoking, and intake of energy, alcohol, and other nutrients including protein from other sources. In addition, mean BP difference after substitution of 3 en% carbohydrates or MUFA with protein was calculated. RESULTS: Total protein and animal protein were not associated with BP (p(trend = 0.62 and 0.71 respectively, both at the expense of carbohydrates and MUFA. Systolic BP was 1.8 mmHg lower (p(trend36 g/d than in the lowest (<27 g/d quintile of plant protein. This inverse association was present both at the expense of carbohydrates and MUFA and more pronounced in individuals with untreated hypertension (-3.6 mmHg than in those with normal (+0.1 mmHg or prehypertensive BP (-0.3 mmHg; p(interaction<0.01. Meat and grain protein were not related to BP. Dairy protein was directly associated with systolic BP (+1.6 mmHg, p(trend<0.01, but not with diastolic BP (p(trend = 0.24. CONCLUSIONS: Total protein and animal protein were not associated with BP in this general untreated Dutch population. Plant protein may be beneficial to BP, especially in people with elevated BP. However, because high intake of plant protein may be a marker of a healthy diet and lifestyle in general, confirmation from randomized controlled trials is warranted.

    This study was conducted to determine the relationship between prayer attendance and general health among adult urban population in Iran. A total of 470 males older than 17 years, chosen by multistage sampling, were investigated. The results showed that people who did not perform prayers compared to those who said prayers on time and performed Nafilahs (supererogatory prayers) were 2.87 (OR 2.87, 95 % CI 1.23-6.70, p = 0.015) times at risk of general health problems. In conclusion, the findings show that increasing the degree of people's belief in prayer can lead to improve general health.

    2000-11-01

    We present a quantitative theory, based on crowd effects, for the market volatility in a Minority Game played by a mixed population. Below a critical concentration of generalized strategy players, we find that the volatility in the crowded regime remains above the random coin-toss value regardless of the `temperature' controlling strategy use. Our theory yields good agreement with numerical simulations.

    Al-Atiyat, R M; Aljumaah, R S

    2014-08-27

    This study aimed to estimate evolutionary distances and to reconstruct phylogeny trees between different Awassi sheep populations. Thirty-two sheep individuals from three different geographical areas of Jordan and the Kingdom of Saudi Arabia (KSA) were randomly sampled. DNA was extracted from the tissue samples and sequenced using the T7 promoter universal primer. Different phylogenetic trees were reconstructed from 0.64-kb DNA sequences using the MEGA software with the best general time reverse distance model. Three methods of distance estimation were then used. The maximum composite likelihood test was considered for reconstructing maximum likelihood, neighbor-joining and UPGMA trees. The maximum likelihood tree indicated three major clusters separated by cytosine (C) and thymine (T). The greatest distance was shown between the South sheep and North sheep. On the other hand, the KSA sheep as an outgroup showed shorter evolutionary distance to the North sheep population than to the others. The neighbor-joining and UPGMA trees showed quite reliable clusters of evolutionary differentiation of Jordan sheep populations from the Saudi population. The overall results support geographical information and ecological types of the sheep populations studied. Summing up, the resulting phylogeny trees may contribute to the limited information about the genetic relatedness and phylogeny of Awassi sheep in nearby Arab countries.

  20. Diagnostic health risk assessment of electronic waste on the general population in developing countries' scenarios

    E-waste is the generic name for technological waste. Even though aspects related to e-waste environmental pollution and human exposure are known, scientific assessments are missing so far on the actual risks for health sustainability of the general population exposed to e-waste scenarios, such as illicit dumping, crude recycling and improper treatment and disposal. In fact, further to occupational and direct local exposure, e-waste scenarios may impact on the environment-to-food chain, thus eliciting a widespread and repeated exposure of the general population to mixtures of toxicants, mainly toxic chemical elements, polycyclic aromatic hydrocarbons and persistent organic pollutants. In the absence of any clear policy on e-waste flow management, the situation in the e-waste receiver countries may become quite scary; accordingly, here we address a diagnostic risk assessment of health issues potentially elicited by e-waste related mixtures of toxicants. Scientific evidence available so far (mainly from China) is discussed with special attention to the concept of health sustainability, i.e. the poor health burden heritage perpetuated through the mother-to-child dyad. Endocrine disruption and neurotoxicity are specifically considered as examples of main health burden issues relevant to perpetuation through life cycle and across generations; toxicological information are considered along with available data on environmental and food contamination and human internal exposure. The risk from exposure to e-waste related mixtures of toxicants of vulnerable subpopulation like breast-fed infants is given special attention. The diagnostic risk assessment demonstrates how e-waste exposure poses an actual public health emergency, as it may entrain significant health risks also for generations to come. Exposure scenarios as well as specific chemicals of major concern may vary in different contexts; for instance, only limited information is available on e-waste related exposures in

    The purpose of this study was to explore the main factors explaining the relative weight of the different attributes that determine the value of oncologic treatments from the different perspectives of healthcare policy makers (HCPM), oncologists, patients and the general population in Spain. Structured interviews were conducted to assess: (1) the importance of the attributes on treatment choice when comparing a new cancer drug with a standard cancer treatment; (2) the importance of survival, quality of life (QoL), costs and innovation in cancer; and (3) the most worrying side effects related to cancer drugs. A total of 188 individuals participated in the study. For all participants, when choosing treatments, the best rated characteristics were greater efficacy, greater safety, treatment adaptation to patients' individual requirements and the rapid reincorporation of patients to their daily activities. There were important differences among participants in their opinion about survival, QoL and cost. In general, oncologists, patients, and the general population gave greater value to gains in QoL than healthcare policy makers. Compared to other participants healthcare policy makers gave greater importance to the economic impact related to oncology treatments. Gains in QoL, survival, safety, cost and innovation are perceived differently by different groups of stakeholders. It is recommended to consider the perspective of different stakeholders in the assessment of a new cancer drugs to obtain more informed decisions when deciding on the most appropriate treatment to use.

    Gender-sensitive tobacco control policies are being challenged, and new directions are being sought because public health efforts have reduced cigarette consumption more substantially among men than among women. To better target women, it would help to identify the protective cultural factors that promote resiliency in women and discourage them from smoking. Whereas western cultures have generated a great deal of gender-specific research and programs on the prevention of smoking in women, Asian cultures have not. Taking a personal and sociocultural perspective, this study examines the effect of gender on smoking behaviors in Taiwan. In a 2004 cross-sectional random-sampled interview survey, 827 adult men and 90 adult women smokers in Taiwan were queried about the time they began smoking, maintenance of their habits, and their readiness to change. The male/female smoking rate ratio was 9.5 (45.7% vs. 4.8%). Men smoked significantly more cigarettes per day than women (18 vs. 11). We found Taiwanese women started smoking around 20 years old, much later than their western counterparts. We also found that whereas the smoking behavior of the men was very sensitive to social environment and structural factors, that of women revolved around their desire to control their weight and handle their emotions. Differences in the smoking behavior of men and women are a result of a different sociocultural environment and the life trajectories and social circumstances embedded within it. Comprehensive tobacco control policies need to be tailored to not just smoking behavior alone or one population alone but to the determinants of smoking behavior in specific groups, for example, women. Even when targeting women, some effort may be needed on targeting women of different ethnicities, for instance, Asian women in whom the prevalence is increasing at alarming rates.

    2007-01-01

    Background Failure to thrive (FTT) in early childhood is associated with subsequent developmental delay and is recognised to reflect relative undernutrition. Although the concept of FTT is widely used, no consensus exists regarding a specific definition, and it is unclear to what extent different anthropometric definitions concur. Objective To compare the prevalence and concurrence of different anthropometric criteria for FTT and test the sensitivity and positive predictive values of these in detecting children with “significant undernutrition”, defined as the combination of slow conditional weight gain and low body mass index (BMI). Methods Seven criteria of FTT, including low weight for age, low BMI, low conditional weight gain and Waterlow's criterion for wasting, were applied to a birth cohort of 6090 Danish infants. The criteria were compared in two age groups: 2–6 and 6–11 months of life. Results 27% of infants met one or more criteria in at least one of the two age groups. The concurrence among the criteria was generally poor, with most children identified by only one criterion. Positive predictive values of different criteria ranged from 1% to 58%. Most single criteria identified either less than half the cases of significant undernutrition (found in 3%) or included far too many, thus having a low positive predictive value. Children with low weight for height tended to be relatively tall. Conclusions No single measurement on its own seems to be adequate for identifying nutritional growth delay. Further longitudinal population studies are needed to investigate the discriminating power of different criteria in detecting significant undernutrition and subsequent outcomes. PMID:16531456

  7. Symptom patterns in dissociative identity disorder patients and the general population.

    Ross, Colin A; Ness, Laura

    2010-01-01

    The authors used the Dissociative Disorders Interview Schedule to compare structured interview symptom patterns in a general population sample (N= 502) and a sample of patients with clinical diagnoses of dissociative identity disorder (N= 303). Based on the Trauma Model, the authors predicted that the patterns would be similar in the 2 samples and that symptom scores would be higher in participants reporting childhood sexual abuse in both samples. They predicted that symptom scores would be higher among women with dissociative identity disorder reporting sexual abuse than among women in the general population reporting sexual abuse, with the clinical sample reporting more severe abuse. These predictions were supported by the data. The authors conclude that symptom patterns in dissociative identity disorder are typical of the normal human response to severe, chronic childhood trauma and have ecological validity for the human race in general.

    Hamstring tears are well recognised in the sporting population. Little is known about these injuries in the general population. Evaluating the rates, patterns and risk factors of non-sporting hamstring tears, compared to sporting related hamstring tears. MEDLINE, EMBASE, CINAHL, and the Cochrane Central Register of Controlled Trials (1989-2015). Studies reporting patients with a grade 2 or 3 hamstring muscle tear, identified clinically, confirmed by MRI imaging or direct visualisation during surgical exploration. 144 sets of linked data were extracted for analysis. Most injuries were in males (81.3%), where mean age at injury was lower (30.2, 95% CI 29.1-31.3) than in females (35.4, 95% CI 32.4-38.4) p = 0.06. Key differences were found in the proportion of non-sporting injuries in patients under and over the age 40 (p = 0.001). The proportion of non-sporting injuries was significantly higher in females compared to males (25.9% female non-sporting injuries, versus 8.5% male; p = 0.02). Avulsions were more frequently reported in non-sporting activities (70.5%). The proportion of such injuries was notably higher in females, though this failed to meet significance (p = 0.124). Grouped by age category a bimodal distribution was noted, with the proportion of avulsions greater in younger (age 40) (p = 0.008). 86.8% of patients returned to pre-injury activity levels with a similar frequency across all study variables; age, activity (sporting vs non-sporting) and injury type (avulsion vs tear). This review highlights a proportion of adults suffering grade 2 or 3 hamstring injuries from activities other than the classic sports trauma. The majority of these non-sporting injuries were avulsion injuries that clustered in older female and skeletally immature patients suggesting a potential link to bone mineral density.

    The Ria of Huelva (south-west Spain) is one of the most polluted fluvial-estuarine systems in the world. Industrial activity delivers huge amounts of pollutants to the local environment, particularly heavy metals and arsenic. Here we aimed to determine urinary levels of As, Cd, Cr, Cu and Ni in a representative sample (n=857) of adults living in the Ria of Huelva. Levels were compared to those from a representative sample of 861 adults of the general urban population of Andalusia (southern Spain) and multiple regression models were developed to identify individual factors associated with urinary levels of these elements. Arsenic levels were significantly higher in the Ria of Huelva as compared to other Andalusian cities, whereas Cd and Ni levels were significantly lower. Despite these differences, levels in both groups were similar to the reference values reported in previous studies for general population. Age, gender, diet and lifestyle were the major factors contributing to the interindividual variation in urinary metals. In conclusion, despite living in a highly polluted area, the population of the Ria of Huelva failed to show higher urinary levels of the studied metals as compared to a reference urban population of the same region.

    Trauma prevention starts with to find out the extent of the problem and who it affects. Insight into morbidity figures is therefore necessary. To explore sex differences in traumatology and secondary medical care utilization in primary care related to age and socio-economic status (SES). Data were obtained from an academic continuous morbidity registration project in the Netherlands in the period from 1996 to 2006, in which 13,000 patients were followed in 10 successive years. Sex differences showed a male excess from childhood to 45 years and women showing almost double trauma rates in the elderly. Low SES was associated with the greatest incidence of traumas. The largest sex difference in incidence above 65 years appeared in the high SES with more traumas in women compared with men. From this age on, female morbidity in traumatology outnumbered male morbidity regardless of SES. Considering use of referrals, we found that in the age group 15-45 years men made a greater use of secondary medical care. However, the vastest gender influence in medical care utilization was noticed in the age group over 65 years, outnumbered with women. Young men and old women are the most at risk for traumatic health problems: men presenting with traumata of the skull, the tibia and ocular trauma's and women with fractures of the femur, humerus and wrist. For both men and women the greatest incidence is in the low SES. Family physicians can play a pivotal role in prevention to focus on their patients with high risks.

    Full Text Available Abstract Background The present study aimed to provide information on awareness of the attributable fraction of cancer causes among the Japanese general population. Methods A nationwide representative sample of 2,000 Japanese aged 20 or older was asked about their perception and level of concern about various environmental and genetic risk factors in relation to cancer prevention, as a part of an Omnibus Survey. Interviews were conducted with 1,355 subjects (609 men and 746 women. Results Among 12 risk factor candidates, the attributable fraction of cancer-causing viral and bacterial infection was considered highest (51%, followed by that of tobacco smoking (43%, stress (39%, and endocrine-disrupting chemicals (37%. On the other hand, the attributable fractions of cancer by charred fish and meat (21% and alcohol drinking (22% were considered low compared with other risk factor candidates. For most risk factors, attributable fraction responses were higher in women than in men. As a whole, the subjects tended to respond with higher values than those estimated by epidemiologic evidence in the West. The attributable fraction of cancer speculated to be genetically determined was 32%, while 36% of cancer was considered preventable by improving lifestyle. Conclusion Our results suggest that awareness of the attributable fraction of cancer causes in the Japanese general population tends to be dominated by cancer-causing infection, occupational exposure, air pollution and food additives rather than major lifestyle factors such as diet.

    The main objective of the study was to explore the factorial structure of the French version of the Schizotypal Personality Questionnaire-Brief (SPQ-B) in a Likert format, in a representative sample of the general population. In addition, differences in the dimensional scores of schizotypy according to gender and age were analyzed. As the study in the general population of schizotypal traits and its determinants has been recently proposed as a way toward the understanding of aetiology and pathophysiology of schizophrenia, consistent self-report tools are crucial to measure psychometric schizotypy. A shorter version of the widely used Schizotypal Personality Questionnaire (SPQ-Brief) has been extensively investigated in different countries, particularly in samples of students or clinical adolescents, and more recently, a few studies used a Likert-type scale format which allows partial endorsement of items and reduces the risk of defensive answers. A sample of 233 subjects representative of the adult population from an urban area near Paris (Créteil) was recruited using the "itinerary method". They completed the French version of the SPQ-B with a 5-point Likert-type response format (1=completely disagree; 5=completely agree). We examined the dimensional structure of the French version of the SPQ-B with a Principal Components Analysis (PCA) followed by a promax rotation. Factor selection was based on Eigenvalues over 1.0 (Kaiser's criterion), Cattell's Scree-plot test, and interpretability of the factors. Items with loadings greater than 0.4 were retained for each dimension. The internal consistency estimate of the dimensions was calculated with Cronbach's α. In order to study the influence of age and gender, we carried out a simple linear regression with the subscales as dependent variables. Our sample was composed of 131 women (mean age=52.5±18.2 years) and 102 men (mean age=53±18.1 years). SPQ-B Likert total scores ranged from 22 to 84 points (mean=43.6

    Upper respiratory tract infection (URI) is a well-documented cause of morbidity, extra expense, and lost training time among basic military trainees (BMTs). The goal of this study was to characterize the clinical presentation of influenza in the BMT population and to better understand how this presentation differs from that of the general Department of Defense (DoD) beneficiary population (non-BMTs). Clinical and demographic data were collected in a prospective study that enrolled DoD beneficiaries presenting to medical treatment facilities in San Antonio, Texas, with URI symptoms between January 2005 and March 2011. Vital signs and symptom duration were collected at the time of enrollment along with basic demographic information. Among 4,448 participants enrolled, 466 (10.5%) tested positive for influenza: 198 of 3,103 BMTs (6.4%) vs. 268 of 1,345 non-BMTs (20%) (p 0.5°F, p 0.5, 95% CI = 0.3-0.8, p 0.5, 95% CI = 0.3-0.8, p standard deviation = 1.4) symptoms, whereas non-BMTs presented with a mean of 6.9 (standard deviation = 1.3) symptoms (p < 0.01). The pretest probability of a BMT presenting with URI symptoms having influenza is significantly lower than that for the general DoD beneficiary population. BMTs with influenza presented sooner, with higher fever, and with fewer overall symptoms than the general DoD beneficiary population. These differences are likely attributable to early reporting and response bias and less likely attributed to age. Military efforts to identify BMTs with suspected influenza infection early and to refer them for treatment promptly are efficacious.

    This paper reports the results of a best–worst scaling (BWS) study to value the Investigating Choice Experiments Capability Measure for Adults (ICECAP-A), a new capability measure among adults, in a UK setting. A main effects plan plus its foldover was used to estimate weights for each of the four levels of all five attributes. The BWS study was administered to 413 randomly sampled individuals, together with sociodemographic and other questions. Scale-adjusted latent class analyses identified two preference and two (variance) scale classes. Ability to characterize preference and scale heterogeneity was limited, but data quality was good, and the final model exhibited a high pseudo-r-squared. After adjusting for heterogeneity, a population tariff was estimated. This showed that ‘attachment’ and ‘stability’ each account for around 22% of the space, and ‘autonomy’, ‘achievement’ and ‘enjoyment’ account for around 18% each. Across all attributes, greater value was placed on the difference between the lowest levels of capability than between the highest. This tariff will enable ICECAP-A to be used in economic evaluation both within the field of health and across public policy generally. © 2013 The Authors.

    Proponents of complementary and alternative medicine argue that these treatments can be used with great effect in addition to, and sometimes instead of, conventional medicine, a position which has drawn sustained opposition from those who advocate an evidence-based approach to the evaluation of treatment efficacy. Using recent survey data from the United Kingdom, this article seeks to establish a clearer understanding of the nature of the public's relationship with complementary and alternative medicine within the general population by focusing on beliefs about the perceived effectiveness of homeopathy, in addition to its reported use. Using recent data from the United Kingdom, we initially demonstrate that reported use and perceived effectiveness are far from coterminous and argue that for a proper understanding of the motivations underpinning public support of complementary and alternative medicine, consideration of both reported use and perceived effectiveness is necessary. We go on to demonstrate that although the profile of homeopathy users differs from those who support this form of medicine, neither outcome is dependent upon peoples' levels of knowledge about science. Instead, the results suggest a far greater explanatory role for need and concerns about conventional medicine.

    Full Text Available Left-handers may have strategic advantages over right-handers in interactive sports and innate superior abilities that are beneficial for sports. Previous studies relied on differing criteria for handedness classification and mostly did not investigate mixed preferences and footedness. Footedness appears to be less influenced by external and societal factors than handedness. Utilizing latent class analysis and structural equation modeling, we investigated in a series of studies (total N > 15300 associations of handedness and footedness with self-reported sporting performance and motor abilities in the general population. Using a discovery and a replication sample (ns = 7658 and 5062, Study 1 revealed replicable beneficial effects of mixed-footedness and left-footedness in team sports, martial arts and fencing, dancing, skiing, and swimming. Study 2 (n = 2592 showed that footedness for unskilled bipedal movement tasks, but not for skilled unipedal tasks, was beneficial for sporting performance. Mixed- and left-footedness had effects on motor abilities that were consistent with published results on better brain interhemispheric communication, but also akin to testosterone-induced effects regarding flexibility, strength, and endurance. Laterality effects were only small. Possible neural and hormonal bases of observed effects need to be examined in future studies.

  20. The musicality of non-musicians: an index for assessing musical sophistication in the general population.

    Full Text Available Musical skills and expertise vary greatly in Western societies. Individuals can differ in their repertoire of musical behaviours as well as in the level of skill they display for any single musical behaviour. The types of musical behaviours we refer to here are broad, ranging from performance on an instrument and listening expertise, to the ability to employ music in functional settings or to communicate about music. In this paper, we first describe the concept of 'musical sophistication' which can be used to describe the multi-faceted nature of musical expertise. Next, we develop a novel measurement instrument, the Goldsmiths Musical Sophistication Index (Gold-MSI to assess self-reported musical skills and behaviours on multiple dimensions in the general population using a large Internet sample (n = 147,636. Thirdly, we report results from several lab studies, demonstrating that the Gold-MSI possesses good psychometric properties, and that self-reported musical sophistication is associated with performance on two listening tasks. Finally, we identify occupation, occupational status, age, gender, and wealth as the main socio-demographic factors associated with musical sophistication. Results are discussed in terms of theoretical accounts of implicit and statistical music learning and with regard to social conditions of sophisticated musical engagement.

    Childhood adversities (CAs) comprise a group of negative experiences individuals may suffer in their lifetimes. The goal of the present study was to investigate the cluster discrimination of CAs through psychometric determination of the common attributes of such experiences for men and women. Parental mental illness, substance misuse, criminality, death, divorce, other parental loss, family violence, physical abuse, sexual abuse, neglect, physical illness, and economic adversity were assessed in a general-population sample (n=5,037). Exploratory and confirmatory factor analysis determined gender-related dimensions of CA. The contribution of each individual adversity was explored through Rasch analysis. Adversities were reported by 53.6% of the sample. A three-factor model of CA dimensions fit the data better for men, and a two-factor model for women. For both genders, the dimension of family maladjustment - encompassing physical abuse, neglect, parental mental disorders, and family violence - was the core cluster of CAs. Women endorsed more CAs than men. Rasch analysis found that sexual abuse, physical illness, parental criminal behavior, parental divorce, and economic adversity were difficult to report in face-to-face interviews. CAs embrace sensitive personal information, clustering of which differed by gender. Acknowledging CAs may have an impact on medical and psychiatric outcomes in adulthood.

    Full Text Available Abstract Background Morphinofobia among the general population (GP and among health care professionals (HP is not without danger for the patients: it may lead to the inappropriate management of debilitating pain. The aim of our study was to explore among GP and HP the representation and attitudes concerning the use of morphine in health care. Methods A cross-sectional study was done among 412 HP (physicians and nurses of the 4 hospitals and 10 community health centers of Beira Interior (Portugaland among 193 persons of the GP randomly selected in public places. Opinions were collected through a translated self-administered questionnaire. Results A significant difference of opinion exists among GP and HP about the use of morphine. The word morphine first suggests drug to GP (36,2% and analgesia to HP (32,9%.. The reasons for not using morphine most frequently cited are: for GP morphine use means advanced disease (56%, risk of addiction (50%, legal requirements (49,7%; for HP it means legal risks (56,3% and adverse side effects of morphine such as somnolence - sedation (30,5% The socio-demographic situation was correlated with the opinions about the use of morphine. Conclusions False beliefs about the use of morphine exist among the studied groups. There seems to be a need for developing information campaigns on pain management and the use of morphine targeting. Better training and more information of HP might also be needed.

    While the prevalence of mental illness is higher in prisons than in the community, less is known about comparative rates of psychotropic medicine prescribing. This is the first study in a decade to determine the prevalence and patterns of psychotropic medication prescribing in prisons. It is also the first study to comprehensively adjust for age when making comparisons with the general population. Four East of England prisons, housing a total of 2222 men and 341 women were recruited to the study. On census days, clinical records were used to identify and collect data on all prisoners with current, valid prescriptions for hypnotic, anxiolytic, antipsychotic, antimanic, antidepressant and/or stimulant medication, as listed in chapters 4.1 to 4.4 of the British National Formulary. Data on 280,168 patients were obtained for comparison purposes from the Clinical Practice Research Datalink. After adjusting for age, rates of psychotropic prescribing in prison were 5.5 and 5.9 times higher than in community-based men and women, respectively. We also found marked differences in the individual psychotropic drugs prescribed in prison and community settings. Further work is necessary to determine whether psychotropic prescribing patterns in prison reflect an appropriate balance between managing mental illness, physical health risks and medication misuse.

    Full Text Available Background: The description of demographic features and associated risk factors provides a perspective for the development of health and prevention policies for psychological screening or referrals. Thus, updated data on epidemiologic profile of depression and anxiety in the society are necessary. This study aims to describe the psychological profile of a general population in central Iran.Methods: This community-based, cross-sectional survey was performed as part of the SEPAHAN project (Study on the Epidemiology of Psychological‐Alimentary Health and Nutrition. The participants were working in 50 different centers across Isfahan Province, Iran. The data on 4628 adults who had completeddemographic questionnaires and psychological questionnaires for depression and anxiety, coping styles,and stressful life events were included in the analysis. The data collection tools were the Demographicinformation questionnaire, Hospital Anxiety and Depression Scale (HADS, Coping Strategies Scale(Cope, and Stressful Life Event (SLE questionnaire.Results: The frequency and intensity of all considered stressors were found to be significantly associated withboth depression and anxiety. Adaptive coping strategies were found to function as protective factors against bothdepression and anxiety. However, avoidance, as a maladaptive coping strategy, was found to be a risk factor.Conclusion: The present survey reveals that the prevalence of depression and anxiety was 28% and 14%,respectively. Scholastic education plays a protective role against both depression and anxiety. All coping strategies, except avoidance, function to protect against depression and anxiety.

    The single-breath carbon monoxide diffusing capacity (DLCOsb) was measured together with ventilatory lung function tests as part of a survey of a general population sample living in Northern Italy (n = 2,481). Based on answers to an interviewer-administered questionnaire, subjects free of respiratory symptoms or diseases were identified. Data from subjects who had never regularly smoked cigarettes were used to derive reference equations for the test indexes, and data from the remaining subjects who had smoked were used to derive regression equations incorporating a term expressing cigarette consumption (cube root of pack-years) and a term indicating current smoking decrement, in order to obtain expected DLCOsb percent predicted. Neither number of cigarettes smoked daily or duration of smoking, in smokers, nor duration of smoking or years since quitting smoking, in ex-smokers, entered significantly the multiple-regression model. The mean values of DLCOsb were only slightly affected by the increasing degree of airway obstruction. When subjects with confirmed asthma were analyzed, after stratifying for different levels of FEV1/FVC ratio, increased mean value of DLCOsb (over 100%) was found in those with an FEV1/FVC ratio between 75 and 65%. This cross-sectional analysis suggests that there is a decrease in DLCOsb with cumulative cigarette consumption even in healthy subjects. Further, it confirms the clinical observations of high DLCOsb values in asthmatic patients, at least in those with an initial degree of chronic airflow obstruction.

    Dyslipidemia and abnormal phospholipid metabolism are frequent in uremic patients and increase their risk of cardiovascular disease (CVD): ω-3 polyunsaturated fatty acids (PUFAs) may reduce this risk in the general population. In this study we compared the plasma and erythrocyte cell membrane composition of PUFAs in a group of Caucasian hemodialysis (HD) patients and in a control group of healthy subjects and evaluated the erythrocyte/cell membrane fatty acid ratio as a marker of the dietary intake of phospholipids. The relationship between ω-3 and ω-6 fatty acids and the possible differences in PUFAs concentrations were also investigated. After obtaining a fully informed consent, a total of ninety-nine HD patients and 160 non uremic control subjects from "Tor Vergata" University Hospital were enrolled into the study. None of them took antioxidant drugs or dietary supplements for at least 90 days prior to the observation. Blood samples were analysed by gas-chromatographic coupled to a mass spectrometric detector.The daily intake of total calories, proteins, lipids and carbohydrates is significantly lower in HD patients than in controls (p HD patients (p HD patients, due to the removal of nutrients during the dialysis and to persistent malnutrition. A dietary treatment addressed to increase plasma ω-3 PUFAs and to optimize ω-6/ω-3 ratio may exert a protective action and reduce the risk of CVD in HD patient.

    In contrast to other European countries, dermatologists in Germany provide health care for a broad spectrum of diseases of the skin and mucous membranes. Current population-based data on the perception of dermatology were lacking to date. Analysis of the perception of dermatology from the general population's perspective with regard to utilization, satisfaction and responsibility. Nation-wide survey on awareness, utilization, rating and image of dermatology in October 2014 through computer-assisted telephone interviews on a representative sample of the adult general population (n = 1015), performed by the FORSA institute. Dermatologists as a medical specialist group are familiar to 88% of the population (2002: 65%), and approx. 82% of respondents underwent dermatological treatment in the past. Satisfaction with this treatment is high to very high in 80-90% of respondents. The majority (60-80%) name dermatologists as the desired primary provider of care for the largest share of common skin diseases. For allergic diseases, mucous membrane diseases, venous disorders and paediatric skin diseases, this rate is significantly below 50%. In Germany, dermatologists are perceived and valued as providers of care. In the case of skin cancer and chronic inflammatory skin diseases, they are experienced as primary care givers, whereas they are associated less frequently than their competence would justify with providing treatment for allergic and mucous membrane diseases and venous disorders. Further education of the general public and medical profession is required. © 2017 European Academy of Dermatology and Venereology.

    Preterm low birth weight (PTLBW) is a public health issue which needs to be dealt with by educating the general female population. One of the major contributing factors is periodontal disease and treatment of the same could reduce the occurrence of PTLBW babies. Therefore, awareness of this among the female population is highly essential. Hence, this survey was planned with the aim to explore the awareness of the general female population regarding the association of periodontal disease and PTLBW. This survey consisted of nine close-ended questions answered by 1284 females. Younger individuals had higher knowledge scores as compared to the older individuals (r = -0.161) and the more educated group had a higher knowledge score as compared to the less educated groups (r = 0.322). Furthermore, married women seemed to be more aware of the relation of PTLBW to periodontal disease as compared to unmarried women. Younger and educated females had better awareness of the association between periodontal diseases and PTLBW. Hence, efforts to educate the general female population on this association could contribute toward the reduction of the risk of PTLBW.

    Full Text Available Raising awareness on a disorder is important for its prevention and for promoting public health. However, for sports injuries like the anterior cruciate ligament (ACL injury no studies have investigated the awareness on risk factors for injury and possible preventative measures in the general population. The sources of information among the population are also unclear. The purpose of the present study was to identify these aspects of public awareness about the ACL injury.A questionnaire was randomly distributed among the general population registered with a web based questionnaire supplier, to recruit 900 participants who were aware about the ACL injury. The questionnaire consisted of two parts: Question 1 asked them about their sources of information regarding the ACL injury; Question 2 asked them about the risk factors for ACL injury. Multivariate logistic regression was used to determine the information sources that provide a good understanding of the risk factors.The leading source of information for ACL injury was television (57.0%. However, the results of logistic regression analysis revealed that television was not an effective medium to create awareness about the risk factors, among the general population. Instead "Lecture by a coach", "Classroom session on Health", and "Newspaper" were significantly more effective in creating a good awareness of the risk factors (p < 0.001.

    measles virus into a pocket of susceptible persons (e.g. vaccination opponents or sceptics) may lead to large outbreaks in the general population, if the general population's vaccination coverage is below the WHO recommended level. Education on the safety of measles vaccine needs to be strengthened to increase measles vaccination coverage. Early intervention may limit spread in schools or kindergartens. Suspected measles has to be reported immediately to the local health authorities in order to allow intervention as early as possible. PMID:21676265

    Toxoplasma gondii is one of the most common protozoan parasites with widespread distribution globally. It is the causative agent of Toxoplasma infection, which is prevalent in human and other warm-blooded vertebrates. While T. gondii infection in healthy people is usually asymptomatic, it can lead to serious pathological effects in congenital cases and immunodeficient patients. We sought to identify the seroprevalence rate of Toxoplasma infection in the Iranian general population to develop a comprehensive description of the disease condition in Iran for future use. Electronic databases (PubMed, Google Scholar, Science Direct, and Scopus) and Persian language databases (Magiran, Scientific Information Database [SID], Iran Medex, and Iran Doc) were searched. Furthermore, graduate student dissertations and proceedings of national parasitology congresses were searched manually. Our search resulted in a total of 35 reports published from 1978 to 2012.These include 22 published articles, 1 unpublished study, 8 proceedings from the Iranian conference of parasitology, and 4 graduate student dissertations, resulting in 52,294 individuals and 23,385 IgG seropositive cases. The random errors method was used for this meta-analysis. The result shows that the overall seroprevalence rate of toxoplasmos is among the general population in Iran was 39.3% (95% CI=33.0%-45.7%). There was no significant difference in the seroprevalence rate between male and female patients. A significant linear trend of increasing overall prevalence by age was noted (P<0.0001). In addition, the data indicates that there are high seroprevalence in groups who have direct contact with cats, consume uncooked meat and raw fruits or vegetables, in farmers and Housewife, individuals who have a low level of education, and live in rural areas. To the best of our knowledge, this is the first systematic review of T. gondii infection seroprevalence in Iran, which shows a high prevalence of Toxoplasma infection

    Objectives. To describe mortality among adults with intellectual disability in England in comparison with the general population. Methods. We conducted a cohort study from 2009 to 2013 using data from 343 general practices. Adults with intellectual disability (n = 16 666; 656 deaths) were compared with age-, gender-, and practice-matched controls (n = 113 562; 1358 deaths). Results. Adults with intellectual disability had higher mortality rates than controls (hazard ratio [HR] = 3.6; 95% confidence interval [CI] = 3.3, 3.9). This risk remained high after adjustment for comorbidity, smoking, and deprivation (HR = 3.1; 95% CI = 2.7, 3.4); it was even higher among adults with intellectual disability and Down syndrome or epilepsy. A total of 37.0% of all deaths among adults with intellectual disability were classified as being amenable to health care intervention, compared with 22.5% in the general population (HR = 5.9; 95% CI = 5.1, 6.8). Conclusions. Mortality among adults with intellectual disability is markedly elevated in comparison with the general population, with more than a third of deaths potentially amenable to health care interventions. This mortality disparity suggests the need to improve access to, and quality of, health care among people with intellectual disability. PMID:27310347

    This study was designed to investigate the phthalates exposure levels in general population in Chongqing City of China, and to determine the possible associations between phthalate exposure and male reproductive function parameters. We recruited 232 general men through Chongqing Family Planning Research Institute and Reproductive Center of Chongqing. In a single spot urine sample from each man, phthalate metabolites, including mono-butyl phthalate (MBP), mono-ethyl phthalate (MEP), mono-(2-ethylhexyl) phthalate (MEHP), mono-benzyl phthalate (MBzP), phthalic acid (PA), and total PA were analyzed using solid phase extraction and coupled with high-performance liquid chromatography and detection by tandem mass spectrometry. Semen parameters were dichotomized based on World Health Organization reference values. Sperm DNA damage were analyzed using the alkaline single-cell gel electrophoresis assay. Reproductive hormones were determined in serum by the radioimmunoassay kit. We observed a weak association between urinary MBP concentration and sperm concentration in Chongqing general population. MBP levels above the median were 1.97 times (95% confidence interval [CI] 0.97-4.04) more likely to have sperm concentration below the reference value. There were no other associations between phthalate metabolites and reproductive function parameters after adjusted for potential risk factors. Our study suggested that general population in Chongqing area of China exposure to the environmental level of phthalate have weak or without adverse effects on the reproduction.

    Measures of population pressure, referring in general to the stress upon the environment by human consumption of resources, are imperative for environmental sustainability studies and management. Development based on resource consumption is the predominant factor of population pressure. This paper presents a spatial model of population pressure by linking consumption associated with regional urbanism and ecosystem services. Maps representing relative geographic degree and extent of natural resource consumption and degree and extent of impacts on surrounding areas are new, and this research represents the theoretical research toward this goal. With development, such maps offer a visualization tool for planners of various services, amenities for people, and conservation planning for ecologist. Urbanization is commonly generalized by census numbers or impervious surface area. The potential geographical extent of urbanism encompasses the environmental resources of the surrounding region that sustain cities. This extent is interpolated using kriging of a variable based on population wealth data from the U.S. Census Bureau. When overlayed with land-use/land-cover data, the results indicate that the greatest estimates of population pressure fall within mixed forest areas. Mixed forest areas result from the spread of cedar woods in previously disturbed areas where further disturbance is then suppressed. Low density areas, such as suburbanization and abandoned farmland are characteristic of mixed forest areas.

    To compare major depressive disorder (MDD) symptomatology within men and women in a large, representative sample of Canadian military personnel and civilians. We used the Canadian Community Health Survey: Mental Health and Well-Being (Cycle 1.2 and Canadian Forces Supplement) (n = 36 984 and n = 8441, respectively) to compare past-year MDD symptomatology among military and civilian women, and military and civilian men. Logistic regression models were used to determine differences in the types of depressive symptoms endorsed in each group. Men in the military with MDD were at lower odds than men in the general population to endorse numerous symptoms of depression, such as hopelessness (adjusted odds ratio [AOR] 0.44; 99% CI 0.23 to 0.83) and inability to cope (AOR 0.53; 99% CI 0.31 to 0.92). Military women with MDD were at lower odds of thinking about their death (AOR 0.52; 99% CI 0.32 to 0.86), relative to women with MDD in the general population. Different MDD symptomatology among males and females in the military, compared with those in the general population, may reflect selection effects (for example, personality characteristics and patterns of comorbidity) or occupational experiences unique to military personnel. Future research examining the mechanisms behind MDD symptomatology in military personnel and civilians is required.

    Childhood Experiences of Adolescents in Boarding Schools. A Comparison with Adolescents in Residential Care and with the General Population Various studies indicate that students in boarding schools experience a lot of violence during their accommodation. However, it is not proved whether adolescents in boarding schools are also a burdensome group regarding early childhood experiences such as neglect and abuse. The aim of the study was to find out more about the experiences of adolescents in boarding schools and to determine whether there are differences between adolescents in residential care and between the general population. Furthermore, it should be examined whether boys and girls differ in their experiences. In the study, adolescents of boarding schools and of residential care all over Germany, starting at the age of 15 (n = 322), were asked regarding physical and emotional neglect/abuse, light/severe parent violence, negative/positive educational behavior of the parents. The results show that students in boarding schools were less likely to be affected by childhood maltreatment and more likely to have experienced positive parental behavior compared to children in residential care. Compared to the general population, students in boarding schools were more often and more severely affected by parental violence. Moreover, girls had experienced parental violence more often than boys. The results indicate that in boarding schools there is a need for support offers for adolescents with a history of violent experiences and that the risk group should be identified directly at the admission to the school.

    Research on the emotional processes associated with Type D personality is important for its further conceptualization. We examined the associations of Type D personality with social and general anxiety symptoms in a large community sample. The aim of the current study was to disentangle the associations of Type D personality and its components with social anxiety and general anxiety in a large sample from the general population. A random sample of 2,475 adults from the general population filled out questionnaires to assess Type D personality (DS-14), social anxiety (SIAS(10), SPS(11), BFNE-II), and general anxiety (HADS-A, GAD-7). Type D individuals were characterized by increased levels of both social and general anxiety. The social inhibition (SI) component of Type D personality was most strongly associated with social interaction anxiety (r = .63), while negative affectivity (NA) was strongly associated with general anxiety (GAD-7: r = .70; HADS-A: r = .66). Within social anxiety, SI was more strongly associated with facets of social interaction anxiety than with social phobia. Multiple regression analysis showed that the synergistic interaction of NA and SI was a predictor of social anxiety (SIAS(10): β = .32, p < .0005; SPS(11): β = .27, p < .0005; BFNE-II: β = .11, p = .007) independent of demographics and the scores on the individual Type D components. This interaction was not a significant predictor of general anxiety. Logistic regression using the dichotomous Type D classification demonstrated a 9.1-fold (95%CI, 7.0-11.8) increased odds of a score in the highest quartile of social interaction anxiety and a 7.6-fold (95%CI, 5.8-9.8) increased odds of high social phobia. Odds ratios for clinically relevant levels of general anxiety were 8.3 (95%CI, 5.5-12.5) for GAD-7 and 6.5 (95%CI, 3.4-12.6) for HADS-A. In the general population, Type D individuals were characterized by both social and general anxiety. The SI component of Type D is strongly associated

    from two large Danish general population cohorts followed for 31 years: the Copenhagen City Heart Study (n = 10 597) and the Copenhagen General Population Study (n = 32 999). We examined the risk of cardiovascular disease (2743 and 3890, respectively, in the two studies) and cancer (2144 and 3241......, respectively) by NOD2/CARD15 genotype using Cox and logistic regressions in both studies. To maximize statistical power, the three NOD2/CARD15 genetic variants were analysed together as follows: noncarriers for all three variants, heterozygotes for one of the three variants and homozygotes for one of the three...... variants pooled with compound heterozygotes for two variants. Results. Multifactorially adjusted hazard ratios for cardiovascular disease and cancer in NOD2/CARD15 heterozygotes or homozygotes/compound heterozygotes versus noncarries did not differ from 1.0 in the Copenhagen City Heart Study...

    The aims of this study were to analyze whether positive and negative affect, social support, and loneliness are factors longitudinally related to suicide ideation in the general population in different age groups. A total of 2,392 individuals from a nationally representative sample of the Spanish general population were evaluated in 2011-2012 and in 2014-2015. After including relevant control variables in the analyses, lower positive affect was prospectively related to ideation in 18- to 59-year-old individuals, whereas feelings of loneliness were related to ideation in 60-year-and-older individuals. Social support was not associated with suicide ideation in any age group. These results are in line with the need for age-tailored suicide prevention programs. The present findings might also suggest that health care professionals should consider feelings of loneliness rather than social support to assess the presence of suicide ideation in older people. © 2017 The American Association of Suicidology.

    To evaluate the chromium (Cr) levels in blood and urine among general population in China between 2009 and 2010, and thereby to analyze its prevalent features. From year 2009 to 2010, a total of 11 983 subjects of general population aged between 6 and 60 year-old were recruited from 24 districts in 8 provinces in eastern, central and western China mainland, by cluster random sampling method. The information about their living environment and health status were collected by questionnaire, and 11 983 blood samples and 11 853 urine samples were also collected. Inductively coupled plasma mass spectrometry (ICP-MS) was applied to test the Cr level both in blood and urine; and the Cr distribution in blood and urine among groups of population in different ages, genders and districts, were then analyzed. Among general population in China, the geometric mean (GM) of Cr concentration in blood was 1.19 µg/L, with median at 1.74 µg /L and 95% percentile at 5.59 µg/L. The Cr concentration in blood among males and females were separately 1.18 µg/L and 1.20 µg/L(P > 0.05); while its GM in the groups of population aged 6 - 12, 12 - 16, 16 - 20, 20 - 30, 30 - 45 and 45 - 60 years old were 1.00, 1.22, 1.01, 1.40, 1.27 and 1.30 µg/L (P populations from eastern, central and western China were 1.00, 1.70 and 1.98 µg/L (P population, the GM of Cr concentration in urine was 0.53 µg/L, with median was lower than 0.42 µg/L and 95% percentile at 3.53 µg/L. The Cr concentration in urine among males and females were separately 0.52 µg/L and 0.53 µg/L (P > 0.05);while its GM in the groups of population aged 6 - 12, 12 - 16, 16 - 20, 20 - 30, 30 - 45 and 45 - 60 years old were 0.56, 0.60, 0.52, 0.50, 0.52 and 0.46 µg/L (P populations from eastern, central and western China were 0.58, population in China, and thereby provided basic data evidence for the following Cr biological monitoring studies in near future.

    It was examined whether women and men (17-45 years) with operated congenital heart disease differ with respect to chances of employment. Patients were compared with the general population. Patients (n = 314) were classified by type of surgery (curative, reparative, palliative) as indicator of initial severity of disease. The second classification was performed according to a system proposed by the New York Heart Association in order to take reported impairments into account. Controls (n = 1165) consisted of a 10% random sample drawn from the German Socio-Economic Panel. Chances of full-time employment decreased as disease severity increased. Chances of part-time and minor employment were higher in patients than among controls. These general effects were because of male patients, while the employment patterns of women did not differ from the control group. Independent of patient status, women were more likely to have lower rates of full-time employment, and the rates of part-time and minor employment were higher. Long-term adaptation to impairments as a result of congenital heart disease differs between women and men with respect to employment status. While female patients do not differ from the general population, males may lower their engagement in paid work.

    International studies have revealed that gay and bisexual men present more mental health problems than the general male population. Furthermore, there is evidence that minority stress predicts mental health problems in gay and bisexual men. The aim of the present study is to provide initial data on mental health differences in Germany and to analyze the effect of minority stress. Mental health data on n = 1903 German gay and bisexual men and n = 958 men from a population-based sample were assessed using a shortened version of the SCL-90-S. The mental health of the two samples was compared. Furthermore, a linear regression was conducted for the gay and bisexual sample: mental health was used as the criterion and minority stressors as predictors. As compared to our population sample, gay and bisexual men demonstrated more mental health problems with a moderate effect size. In the regression, minority stress predicted mental health problems in the gay and bisexual sample. We observed pronounced mental health differences between gay and bisexual men versus the population sample. These differences could be at least partly due to the minority stress gay and bisexual men face. Research should focus on how to reduce and cope with minority stress.

    Full Text Available Background. Polychlorinated biphenyls (PCBs have been recognized as human carcinogens and cause liver cancer in animal experimental studies. However, no study investigated their association with hepatocellular carcinoma (HCC so far.  This study aimed to evaluate the serum PCB concentration in HCC patients and in healthy subjects of the general population living in Brescia, North Italy, a highly industrialized area with heavy PCB environmental pollution due to the presence of a PCB producing factory. Methods. Lipid-adjusted PCB concentrations, computed as the sum of 24 congeners, were measured in the serum of 101 HCC patients and in 101 healthy subjects of the same age and gender.Results. Hepatitis B and C virus infection and history of heavy alcohol intake were found, alone and combined, in 87% of HCC patients. No difference was found in PCB serum concentration of HCC patients with and without, and according to, the major risk factors for liver disease. No significant difference was observed in serum total PCB concentration between HCC patients (median: 1081; range: 287.0-3182.0 ng/g lipid and healthy subjects (median: 1199.3; range: 225.7-22825 ng/g lipid. PCB congeners 118, 138, 153, 156, 180 and 194 were the only ones found over the detection limit in at least 30% of HCC patients. The serum level of PCB 118, but not that of other congeners, was higher in HCC patients than in healthy subjects.Conclusion. These findings  do not support the hypothesis that PCBs play an important role in HCC development, although a contribution by some specific congeners cannot be ruled out.

    In recent years links among vitamin D deficiency, inflammation and cardio-metabolic disease were proposed. As information regarding the associations between vitamin D and inflammatory markers in the general population is sparse, we investigated the associations of 25-hydroxy vitamin D [25(OH)D] with high-sensitivity C-reactive protein (hs-CRP), fibrinogen and white blood cell count (WBC). The study population comprised 2723 men and women aged 25-88 years from the first follow-up of the Study of Health in Pomerania. Analyses of variance, linear and logistic regressions were performed to assess the associations between 25(OH)D and the three inflammatory markers. The models were adjusted for age, sex, waist circumference, diabetes mellitus, dyslipidemia, anti-inflammatory medication and month of blood sampling. The association between 25(OH)D and WBC was assessed separately in smokers (n = 718) and non-smokers (n = 2005) as effect modification was observed. We detected a U-shaped association between 25(OH)D and hs-CRP with a nadir of 21-25 ng/ml in fully-adjusted linear regression models with restricted cubic splines (p < 0.01; p' < 0.01). We further detected an inverse association between 25(OH)D and fibrinogen (p < 0.01). In addition, there was an inverse association between 25(OH)D and WBC in smokers (p = 0.02) but no association in non-smokers (p = 0.73). Our study confirms a potential role of 25(OH)D in chronic inflammation. Yet, different inflammatory biomarkers are differently associated with 25(OH)D. Beneficial effects of increasing 25(OH)D were observed for fibrinogen and WBC (in smokers only). In contrast, the U-shaped association between 25(OH)D and hs-CRP indicates that ever-increasing 25(OH)D concentrations may also be related to proinflammatory states. Copyright © 2014 Elsevier Inc.

    Epidemiological studies on air pollution have mainly been interested in the effects of short- or long-term exposure on patients suffering from respiratory illnesses. Fewer studies have addressed the acute effects of air pollution on respiratory symptoms in the general population. We conducted a review of the literature over the last 16years that has addressed the impact of atmospheric pollution on respiratory symptoms in the general population to estimate the magnitude of effect. The majority of studies demonstrated a significant association between exposure to air pollutants and the occurrence of respiratory symptoms, without any threshold. Although a link between atmospheric pollution and respiratory symptoms has been demonstrated, knowledge of the effects of specific air pollutants and the effect of pollution on particular vulnerable groups (infants, young children, the elderly) is still limited. There is a need for further studies in this area. Copyright 2010 SPLF. Published by Elsevier Masson SAS. All rights reserved.

    Adolescents' leisure activities are increasingly focusing on Internet activities, and today, these coexist with traditional leisure activities such as sport and meeting friends. The purpose of the present study was to investigate leisure activities, particularly Internet activities, among boys and girls with ADHD, and compare these with boys and girls from the general population. The objective was also to explore how traditional leisure activities and Internet activities interrelate among adolescents with ADHD. Adolescents with ADHD (n = 102) were compared with adolescents from the general population on leisure activities and Internet use. Leisure activities among adolescents with ADHD tended to focus on Internet activities, particularly online games. Internet activities were broadening leisure activities among adolescents with ADHD, rather than being a substitute for traditional leisure activities. Internet activities may provide adolescents with ADHD accessible means of social interaction. © The Author(s) 2015.

    Background: Knowledge about mortality rates (MRs) in patients with chronic hepatitis C (CHC) with cirrhosis is limited. This study aimed to estimate all-cause MRs among patients with CHC with or without cirrhosis in Denmark compared with the general population. Methods: Patients registered...... in the Danish Database for Hepatitis B and C with CHC and a liver fibrosis assessment were eligible for inclusion. Liver fibrosis was assessed by means of liver biopsy, transient elastography, and clinical cirrhosis. Up to 20 sex- and age-matched individuals per patient were identified in the general population....... Data were extracted from nationwide registries. Results: A total of 3410 patients with CHC (1014 with cirrhosis), and 67 315 matched individuals were included. Adjusted MR ratios (MRRs) between patients with or without cirrhosis and their comparison cohorts were 5.64 (95% confidence interval [CI], 4...

    Health-related quality of life (HRQOL) is a vital benchmark to assess the effects of health interventions and policies. Measuring HRQOL of the general population is essential to establish a reference for health outcomes evaluations. However, evidence on HRQOL of general populations in low and middle income countries is very limited. This study aimed to measure HRQOL of the Vietnamese population by using the EuroQol-5 dimensions-5 levels (EQ-5D-5L) instrument and determine its associated factors. A cross-sectional study was performed in Hanoi with 1571 residences in Hanoi, the capital city of Vietnam. EQ-5D-5L and EQ- visual analogue scale (EQ-VAS) were used to assess HRQOL. Potential covariates included socio-demographic characteristics, having acute symptoms in the last four weeks, chronic diseases in the last three months, having multiple health issues, and health service utilisation in the last twelve months. A generalized linear model was employed to identify the association between HRQOL and covariates. Overall, the mean EQ-5D utility index was 0.91 (SD = 0.15), and the mean EQ-VAS score was 87.4 (SD = 14.3). The highest proportion of respondents reporting any problems was in Usual activities (24.3%), followed by Anxiety/Depression (15.2%) and Pain/Discomfort (10.0%), while the lowest percentage was in Self-care (2.5%). Lower HRQOL composite scores were related to unemployment, lower income, higher education, living in urban areas, having chronic diseases, having multiple health issues and using health service. For any health problem self-reported by respondents, the health utility reduced by 0.02 (respiratory diseases) to 0.15 (musculoskeletal diseases). Health utility of the general population and reductions for self-reported health problems in this study are useful for future population health evaluations and comparisons. It also informs the development of interventions to reduce health problems of the general population.

    To compare mortality rates, underlying causes of death, excess mortality and years of potential life lost (YPLL) among rheumatoid arthritis (RA) patients relative to the general population. We studied an inception cohort of 87,114 Ontario RA patients and 348,456 age/sex/area-matched general population comparators over 2000 to 2013. All-cause, cause-specific, and excess mortality rates, mortality rate ratios (MRRs), and YPLL were estimated. A total of 11,778 (14% of) RA patients and 32,472 (9% of) comparators died during 508,385 and 1,769,365 person-years (PY) of follow-up, respectively, for corresponding mortality rates of 232 (95% CI 228, 236) and 184 (95% CI 182, 186) per 10,000 PYs. Leading causes of death in both groups were diseases of the circulatory system, cancer, and respiratory conditions. Increased mortality for all-cause and specific causes was observed in RA relative to the general population. MRRs were elevated for most causes of death. Age-specific mortality ratios illustrated a high excess mortality among RA patients under 45 years of age for respiratory disease and circulatory disease. RA patients lost 7,436 potential years of life per 10,000 persons, compared with 4,083 YPLL among those without RA. Mortality rates were increased in RA patients relative to the general population across most causes of death. The potential life years lost (before the age of 75) among RA patients was roughly double that among those without RA, reflecting higher rate ratios for most causes of death and RA patients dying at earlier ages.

    The 11th General Census of Population and Housing conducted in March 1990 enumerated 2,204,054 inhabitants in Sinaloa, for a density of 37.9 per sq. km. Sinaloa's population thus increased sevenfold from 297,000 in 1900. The proportion of Sinalioans in Mexico's population increased from 2.2% in 1900 to 2.7% in 1990. 38.4% of the population was under age 14, 57.0% was 14064, and 4.6% as over 65. The greatest challenge for the year 2010 will be to meet the demand for educational facilities, employment, and services for the growing elderly population. Sinaloa's population grew at an annual rate of 1.1 between 1980-90. 17 of its 18 municipios showed slowing growth rates between 1980-90, with only Escuinapa increasing its rate. Sinaloa's growth rate of 1.8% is still relatively high, and the population in the year 2000 is projected at 2.6 million. Population distribution and migration present problems that should be more actively addressed. Urban-urban migration is increasing in importance. In 1990, Sinaloa had 5247 localities of which only 85 had more than 2500 inhabitants and 4717 had fewer than 500. Growth of midsize localities with 500-2499 inhabitants may constitute an alternative allowing the demographic deconcentration and decentralization that Sinaloa urgently requires. The lack of jobs, infrastructure, educational and health services, housing, and food in the dispersed 4717 communities with fewer than 500 inhabitants makes them sources of emigration. Sinaloa's population is concentrated along the coast and in the 3 valleys of the north and central regions, which contain 80.8% of the population. One-third of the population lives on 12.1% of the territory in 2 municipios, while 12 municipios covering 67% of the territory contain just 24% of the population. Sinaloa's growth rate has declined from 4.3% between 1960-70 to 3.7% from 1970-80 and 1.8% in 1980-90.

    There is now substantial evidence that autistic-like traits in the general population lie on a continuum, with clinical autism spectrum disorders (ASD) representing the extreme end of this distribution. In this study, we sought to evaluate five independently identified genetic associations with ASD with autistic-like traits in the general population. In the study cohort, clinical phenotype and genomewide association genotype data were obtained from the Western Australian Pregnancy Cohort (Raine) Study. The outcome measure used was the Autism Spectrum Quotient (AQ), a quantitative measure of autistic-like traits of individuals in the cohort. Total AQ scores were calculated for each individual, as well as scores for three subscales. Five candidate single nucleotide polymorphism (SNP) associations with ASD, reported in previously published genomewide association studies, were selected using a nominal cutoff value of P less than 1.0×10. We tested whether these five SNPs were associated with total AQ and the subscales, after adjustment for possible confounders. SNP rs4141463 located in the macro domain containing 2 (MACROD2) gene was significantly associated with the Communication/Mindreading subscale. No other SNP was significantly associated with total AQ or the subscales. The MACROD2 gene is a strong positional candidate risk factor for autistic-like traits in the general population.

    To obtain joint hypermobility classes in children from the general population and to study their characteristics in relation to anxiety measures. A total of 336 nine-year-old children from the general population were clinically assessed through 9 items of hypermobility, and their parents reported about the severity of anxiety symptoms. Latent class analysis was estimated to group the children according to the presence of hypermobility symptoms, and the obtained classes were related to anxiety. A 2-class solution, labeled as high hypermobility and low hypermobility, best fitted the data. Children in the high hypermobility group scored higher in separation anxiety, social phobia, physical injury fears, and total anxiety than did those in the low group. When applying the threshold reference scores to the total anxiety score, 7.4% of children in the high hypermobility group versus 6% in the low group were reported to experience clinical elevations on total anxiety. High symptoms of hypermobility are associated with higher scores in anxiety symptoms in children from the general population. Children with frequent symptoms of hypermobility may benefit from screening for anxiety symptoms because a subset of them are experiencing clinical elevations and may need comprehensive physical and psychological treatment.

    The aims of this study were to investigate the distribution of sleep quality and its relationship with the prevalence of pain among rural Chinese people and to explore the association between sleep quality and pain intensity among the general population in real-life settings. This cross-sectional survey included a total of 2052 adults from rural areas in Liuyang, Hunan Province, recruited through random multistage sampling. The distributions of sleep quality and pain prevalence among the participants over a 4-week period were described. Because of multicollinearity among variables, the influence of self-rated sleep quality and psychosocial covariates on pain intensity was explored using a ridge regression model. The data showed that participants reporting all categories of sleep quality experienced some degree of pain. Sleep quality, along with physical and mental health, was a negative predictor of pain intensity among the general population. Symptoms of depression positively predicted pain intensity. Poor sleep quality increased pain intensity among the participants. Both previous research and the present data suggest that improving sleep quality may significantly decrease pain intensity in the general population. The relationship between sleep and pain may be bidirectional. This finding also suggests that treatment for sleep disorders and insomnia should be addressed in future efforts to alleviate pain intensity.

    The purpose of this study was to determine which zoonoses should the general population be more aware of. We conducted qualitative research (Delphi method) on thirty veterinarians who were selected from the whole country. Twenty-four diseases were selected. The reasons for their selection were classified into three categories: "Amount of knowledge, attitude and behavior", "Clinicoepidemiologic characteristics" and "Social characteristics". More than half of the top ten zoonoses are those that are not transmitted from humans to humans, with rabies in the first place, avian influenza (with its high pathogenicity) in the second place and psittacosis in the third place. From the top ten diseases, it is considered that the prevention of animal-to-human transmission should be emphasized. In addition, from the reasons for the selection, it is suggested that it is necessary to review social characteristics, such as the inadequacy of quarantine and the insufficiencies of legal systems. As for the zoonoses that are transmitted from humans to humans, it will be indispensable in the future to widely spread information on zoonoses and enlighten the general population about them. It is thought that this survey can be a basis for selecting a zoonosis that should be given priority in enlightening the general population.

    To investigate the employment status of lung cancer survivors and the work-related problems they face. Although the number of lung cancer survivors is increasing, little is known about their employment and work-related issues. We enrolled 830 lung cancer survivors 12 months after lung cancer curative surgery (median time after diagnosis, 4.11 years) and 1000 volunteers from the general population. All participants completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, Core 30-item and a questionnaire that included items relating to their jobs. We used logistic regression analysis to identify independent predictors of unemployment. The employment rate of lung cancer survivors decreased from 68.6% at the time of diagnosis to 38.8% after treatment, which was significantly lower than the employment rate of the general population (63.5%; adjusted odds ratio = 2.31, 95% confidence interval: 1.66-3.22). The posttreatment unemployment rate was higher for women than for men. Among survivors, employment was inversely associated with older age, household income, number of comorbidities, and poor social functioning. Fatigue (78.6%) was the most common work-related problem reported by survivors. Lung cancer survivors experienced more difficulties in employment than did the general population. Age, monthly household income, number of comorbidities, and social functioning appear to be important factors influencing employment status. These findings suggest that lung cancer survivors need support to cope with the financial impact of cancer.

    Constipation is a frequent health problem leading to great discomfort to the person and affects his or her quality of life. It is considered to be highly prevalent in the general population, but there is little data supporting the findings. This study was undertaken with an objective to assess the prevalence of constipation and its associated factors among the general population of Dadu Majra Colony, UT, Chandigarh, India. A total of 505 individuals were interviewed through structured questionnaire based on ROME II criteria for constipation. Results revealed that the prevalence of self-reported constipation within the last 1 year was 24.8% whereas 16.8% of participants had constipation according to the Rome II criteria. Most of the subjects (83%) were within the age group of 18-59 years with mean age (years) of 38.64 ± 15.57. Constipation was significantly more frequent in females than in males (20% vs. 13%) and in nonworking population than in working population (20% vs. 12%). Poor dietary habits, lesser fluid intake per day, and lesser physical activity were found to be significant factors leading to the constipation. About 18% of constipated subjects reported physicians' consultation, whereas 8% reported the use of laxatives to relieve their constipation.

    Although likely benefits of aromatherapy are well documented, little is known about essential oils consumption and exposure to molecules present in the oils. The aim of our study was to determine usage patterns of 12 types of essential oils among a quite large panel, sorted per sex and quintile of age from birth to 70. A survey was conducted in September 2014 among 1507 French individuals, selected to build a representative panel of the general population. The key point of our study, apart from the fact that it has never been done among general population, was the focus on dermal exposure. Information about types of essential oils used, skin areas exposed, frequencies and quantities were collected. Our work revealed that some sub-populations could be significantly exposed to molecules of toxicological concern, especially in terms of skin sensitization. This work is the first step to assess human exposure to these molecules, and will help safety authorities and risk managers to protect the population. Copyright © 2016 Elsevier Inc.

    Occupational airborne exposure was examined for a stratified sample (N = 1275) of the general population aged 18-73 years in Hordaland County, Norway. The subjects identified all jobs of more than six months since leaving school and stated whether they had been occupationally exposed to specific agents and work processes potentially harmful to the lungs. The prevalence in the population ever having been exposed was 18% for asbestos, 9% for quartz, 5% for aluminum dust, 6% for wood dust, 12% for metal gases, 12% for welding, 9% for soldering, and 1% for hairdressing. According to occupational title (last job), 3% of the population had held a job with a high degree of airborne exposure, 26% a job with moderate exposure, and 70% a job with no airborne exposure. During their worklife both the men and the women tended to leave polluted jobs more often than unpolluted jobs. Occupational exposure to airborne pollutants potentially harmful to the lungs is widespread in this Norwegian general population.

    Background The interest in complementary and alternative medicine (CAM) has increased during the past decade and the attitude of the general public is mainly positive, but the debate about the clinical effectiveness of these therapies remains controversial among many medical professionals. Methods We conducted a systematic search of the existing literature utilizing different databases, including PubMed/Medline, PSYNDEX, and PsycLit, to research the use and acceptance of CAM among the general population and medical personnel. A special focus on CAM-referring literature was set by limiting the PubMed search to “Complementary Medicine” and adding two other search engines: CAMbase (www.cambase.de) and CAMRESEARCH (www.camresearch.net). These engines were used to reveal publications that at the time of the review were not indexed in PubMed. Results A total of 16 papers met the scope criteria. Prevalence rates of CAM in each of the included studies were between 5% and 74.8%. We found a higher utilization of homeopathy and acupuncture in German-speaking countries. Excluding any form of spiritual prayer, the data demonstrate that chiropractic manipulation, herbal medicine, massage, and homeopathy were the therapies most commonly used by the general population. We identified sex, age, and education as predictors of CAM utilization: More users were women, middle aged, and more educated. The ailments most often associated with CAM utilization included back pain or pathology, depression, insomnia, severe headache or migraine, and stomach or intestinal illnesses. Medical students were the most critical toward CAM. Compared to students of other professions (ie, nursing students: 44.7%, pharmacy students: 18.2%), medical students reported the least consultation with a CAM practitioner (10%). Conclusions The present data demonstrate an increase of CAM usage from 1990 through 2006 in all countries investigated. We found geographical differences, as well as differences between

    HIV prevalence is disproportionately high among female sex workers compared to the general population. Many African countries lack useful data on the size of female sex worker populations to inform national HIV programmes. A female sex worker size estimation exercise using three different venue-based methodologies was conducted among female sex workers in all provinces of Rwanda in August 2010. The female sex worker national population size was estimated using capture-recapture and enumeration methods, and the multiplier method was used to estimate the size of the female sex worker population in Kigali. A structured questionnaire was also used to supplement the data. The estimated number of female sex workers by the capture-recapture method was 3205 (95% confidence interval: 2998-3412). The female sex worker size was estimated at 3348 using the enumeration method. In Kigali, the female sex worker size was estimated at 2253 (95% confidence interval: 1916-2524) using the multiplier method. Nearly 80% of all female sex workers in Rwanda were found to be based in the capital, Kigali. This study provided a first-time estimate of the female sex worker population size in Rwanda using capture-recapture, enumeration, and multiplier methods. The capture-recapture and enumeration methods provided similar estimates of female sex worker in Rwanda. Combination of such size estimation methods is feasible and productive in low-resource settings and should be considered vital to inform national HIV programmes. © The Author(s) 2015.

    The objective was to compare the pattern of exposure to second-hand smoke (SHS) among non-smokers in the general population and in hospitality workers. We used the adult (16-64 years) non-smokers of two independent studies (general population and hospitality workers) in Spain. We assessed the exposure to SHS by means of questionnaire and salivary cotinine concentration. The salivary cotinine concentration by sex, age, educational level, day of week of saliva collection, and exposure to SHS were always higher in hospitality workers than in the general population. Our results indicated that non-smoker hospitality workers have higher levels of exposure to SHS than general population.

    Introduction: Single-nucleotide polymorphisms (SNPs) in interleukin 1β (IL-1β) gene have been known to be associated with increased susceptibility to chronic periodontitis among various ethnic populations. SNPs are more commonly observed at loci + 3954 and − 511. The aim of this study was to evaluate the role of IL-1β gene polymorphism at loci +3954 and − 511, and its association with severe chronic generalized periodontitis among the ethnic Malay, Chinese, and Indians within the Malaysian population. Materials and Methods: Saliva samples from 120 subjects (60 cases and 60 controls) in the age group of 25–50 years were collected for isolation of genetic material using Norgen technique. Clinical attachment loss of ≥5 mm was considered as severe chronic generalized periodontitis. SNP's at loci +3954 and − 511 were identified and analyzed using Kompetitive Allele Specific Polymerase Chain Reaction Genotyping System (KASP™).

    Bondage and discipline, dominance and submission, and sadism and masochism (BDSM) is gaining popularity through the mainstream media. Nevertheless, very little is known about the prevalence of BDSM-related fantasies and activities in the general population. To determine the prevalence of BDSM fantasies and behavioral involvement in four different age groups of the general population in Belgium. By use of a cross-sectional survey questionnaire, the level of interest in several BDSM-related activities was investigated in a sample representative of the general Belgian population (N = 1,027). The questionnaire evaluated interest in 54 BDSM activities and 14 fetishes. Self-identification as BDSM practitioner, situational context of BDSM practice, age at awareness of these interests, and transparency to others were queried. Individual item scores and summary scores on four BDSM categories were included in the analyses. A high interest in BDSM-related activities in the general population was found because 46.8% of the total sample had ever performed at least one BDSM-related activity and an additional 22% indicated having (had) fantasies about it. Interestingly, 12.5% of the total population indicated performing at least one BDSM-related activity on a regular basis. When asked whether they saw themselves as being interested in BDSM, 26% stated this to be the case and 7.6% self-identified as BDSM practitioners. Interests in dominant and submissive activities were comparable and, remarkably, were highly intercorrelated. BDSM and fetish interests were significantly higher in men than in women. The older group (48-65 years) had significantly lower BDSM scores compared with their younger peers. Of participants with a BDSM interest, 61.4% became aware of it before 25 years of age. There is a high level of interest in BDSM in the general population, which strongly argues against stigmatization and pathologic characterization of these interests. This is the first thorough study

    deberse a un grado mayor de mixtura en los mestizos de Bolivia con grupos étnicos andinos, y/o menos rasgos rurales y mayor mixtura caucásica en los mestizos peruanos reportados en la literatura. Estos hallazgos podrían tener un impacto con respecto a la eficacia de formas modernas de inmunización a través de vacunas de ADN en población andina, y en la identificación de riesgo para ciertas condiciones médicas. Data on the genetic background of Peruvian and Bolivian populations is still scarce. Studies have shown that mestizos (i.e. mixed, but of predominantly Native American ancestry present several HLA alleles originally described in genetically isolated Amerindian tribes, and that Peruvian and Bolivian mestizos are closely genetically related. Using Reverse Line Blot Assay, HLA typing for Class I (HLA-A, HLA-B, and HLA-Cw as well as for Class II (HLA-DRB1 and HLA-DQB1 alleles was performed in 57 Bolivian mestizos. Subjects came mainly from La Paz (the main city in the Bolivian Andes and three other important cities located in the Bolivian Central Valley (Sucre, Tarija and Tupiza. Comparison of the allele frequencies of Bolivian mestizos with available data from the literature from Peruvian mestizos, revealed that Class I HLA-Cw*01, and B*40 alleles were higher in the Peruvian mestizo group (Chi-sq = 4,87 p<0,05 and chi-sq = 7,56 p<0,01 respectively. Regarding Class II alleles, HLA-DRB1*1101 and DRB1*1302 alleles were higher in Peruvian mestizos (Chi-sq = 5,12 p<.05 chi-sq = 3,8 p = 0.05 respectively, while HLA-DQB1*0402 was significantly higher in Bolivian mestizos (Chi-sq = 47,2 p<.0001. Differences in allele frequencies, and the absence or presence of certain alleles in either group could be due to a higher grade of admixture with Andean ethnic groups in the mestizos from Bolivia and/or less rural traits and more white (Caucasian admixture in the Peruvian mestizos reported in the literature. These findings may have an impact regarding efficacies of modern

    To study the prevalence of dual diagnosis (presence of a substance use disorder and an associated mental disorder) in the general population of a small town in the department of Antioquia in Colombia, through secondary analysis of survey data on Mental Health held in this city in 2011. With a sample of 415 subjects, the interview Composite International Diagnostic Interview (CIDI), WHO CAPI version, was used and statistical analysis was performed using SPSS v.21. The prevalence of dual diagnosis, considering that the presence of a diagnosis of mental disorder and a disorder snuff use of different substances was 7.2%. Substances with higher prevalence of use in life for individuals with dual diagnosis were alcohol (96.7%), marijuana (80.0%), cocaine and derivatives (33.3%), heroin (23.3%) and finally no prescription tranquilizers (13.3%), finding statistical association between drug use and dual diagnosis. Major depression (40%), oppositional defiant disorder (36.7%), posttraumatic stress (33.3%), specific phobia and attention deficit (26.7%) are the most prevalent disorders in individuals with dual diagnosis of this sample. Alcohol or drugs consumption and fulfilling diagnostic criteria for dual diagnosis have a significant statistical association for consumption of drugs like marijuana, cocaine, heroin and prescription medications (P1.00, very high when the drug is heroin consumed (RD=38.754) or non-prescription medications (RD=29.462). A family history of disease and drug use has a high statistical association with dual diagnosis, with a higher association with a history of mental illness (P<.001; RD=3.677). The study reports on the prevalence of subjects with dual diagnosis in a Colombian population. Alcohol, marijuana, cocaine and heroin are derivatives and substances mostly consumed by these patients and the most prevalent mental disorders are depression, TOD and posttraumatic stress. These findings motivate clinicians to more actively seek the presence of

    Purpose: To investigate the frequency of non-traumatic acute abdominal emergencies in end-stage renal disease (ESRD) (peritoneal dialysis (PD) and haemodialysis (HD)) patients and in the general population as diagnosed by computed tomography (CT) imaging. Methods: The abdominal CT findings of ESRD patients with non-traumatic acute abdominal pain during the years 2001–2010 have been retrospectively evaluated. Thirty-three HD (14 females, 19 males, mean age: 62 ± 10.5) and 22 PD patients (12 females, 10 males, mean age: 59 ± 9.4) with acute abdominal pathology based on their CT scans have been included into the study. In addition, 127 individuals (68 females, 59 males, mean age: 40.7 ± 12.8) with normal renal functions who presented with non-traumatic acute abdominal pain diagnosed with an acute abdominal pathology based on their CT scans have been prospectively evaluated during the years 2009–2010. Results: While the most frequent etiology in PD patients was peritonitis (45.4%), acute pancreatitis (13.6%) and perforation (18.1), and in HD patients it was nonocclusive mesenteric ischemia (18.1%) and spontaneous intraabdominal bleeding (21.2%). The basic causes of acute abdomen in the general population were ureteral stone (34.6%) and appendicitis (18.1%). Conclusions: The causes of acute abdominal pain in ESRD patients is significantly different when compared to the general population. And within this special patient population the etiology of acute abdomen differs depending on the renal replacement therapy modality they are receiving. Thus, the causes of acute abdomen in PD patients are mostly peritonitis, acute pancreatitis, and perforation, while being mostly nonocclusive mesenteric ischemia and spontaneous intraabdominal bleeding in patients receiving HD therapy.

    Smoking is a primary risk factor for cancer development. While most research has focused on smoking cigarettes, the increasing popularity of shisha or water pipe smoking has received less attention. This study measured the prevalence and risk factors for shisha and cigarette smoking and related knowledge. This cross-sectional analytical study was conducted in Shah Alam, Malaysia. Participants aged ≥ 18 years were selected from restaurants. Data regarding demographic variables, smoking patterns, and knowledge about shisha smoking were collected in local languages. Logistic regression was performed to assess risk factors. Of 239 participants, 61.9 % were male and 99.2% revealed their smoking status. Some 57.4% were smokers: 50.7% only cigarettes, 5.9% only shisha and 42% both. Mean age of starting cigarette smoking was 17.5 ± 2.4 years and for shisha smoking 18.7 ± 2.0 years. In a univariate model, male gender, age 33-52 years and monthly income > MYR 4,000 increased the risk and unemployment and being a student decreased the risk. In a multivariate model, male gender increased the risk of smoking, while being a student decreased the risk, adjusting for age and income. The perception of shisha being less harmful than cigarettes was present in 14.6% and 7.5% had the opinion that shisha is not harmful at all, while 21.7% said that it is less addictive than cigarettes, 39.7% said that shisha did not contain tar and nicotine, 34.3% said that it did not contain carbon monoxide and 24.3% thought that shisha did not cause health problems. Prevalence of shisha and cigarette smoking is high in the general population in Malaysia and knowledge about shisha smoking is relatively low. The findings of our study might have implications for understanding similarities and differences in incidence of shisha and cigarette smoking in other cultural/geographic regions.

    Respiratory symptoms during exercise are common and might limit adolescents' ability to take part in physical activity. To estimate the prevalence, determinants and consequences of exercise-induced dyspnea (EID) on daily life in a general population of 12-13 year old adolescents. A letter was sent to the parents of all 12-13 year old adolescents in the city of Uppsala (n = 3838). Parents were asked to complete a questionnaire together with their child on EID, asthma and allergy, consequences for daily life (wheeze, day time- and nocturnal dyspnea) and physical activity. The response rate was 60% (n = 2309). Fourteen percent (n = 330) reported EID, i.e. had experienced an attack of shortness of breath that occurred after strenuous activity within the last 12 months. Female gender, ever-asthma and rhinitis were independently associated with an increased risk of EID. Ever-asthma was reported by 14.6% (n = 338), and 5.4% (n = 128) had both EID and ever-asthma. Sixty-one percent (n = 202) of the participants with EID did not have a diagnosis of asthma. In addition to rhinitis, participants with EID reported current wheeze and day-time as well as nocturnal dyspnea more often than the group without EID. No difference was found in the level of physical activity between participants with and without EID. Adolescents with undiagnosed exercise-induced dyspnea have respiratory symptoms and are affected in daily life but have the same level of physical activity as adolescents without exercise-induced respiratory symptoms.

    In 2010, the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) was developed, based on the concept of the International Classification of Functioning, Disability and Health (ICF). The ICF provides a common language and framework for health and health-related status and attempts to integrate the biopsychosocial model as a multidimensional perspective in understanding functioning. Activities and participation (AP) is one salient component of the ICF refers to the execution of a task by an individual, and how such tasks are involved in their daily life. It is essential to examine the gap between the general adult population and adults with disabilities. This gap may be attributed to health status, personal factors, and natural and social environments, which include social and health services and policies. The purposes: (1) To develop a normative activity and participation (AP) value for the adult population and people with disabilities; and (2) to compare the gap in AP normative values between the two groups in Taiwan. We use the WHODAS 2.0 to survey and develop a normative AP value for the general adult population, and used secondary data from National Disability Eligibility Determination System (NDEDS) of Taiwan to describe the AP functioning distribution of adult with disability. There were 1100 participants, selected by stratified proportional sampling from two cities. There were also 144,850 participants who were adults with disability, selected from the secondary database in Taiwan. The AP curve for the disabled population increased rapidly at the beginning. The summary score was 13.21 in the performance at 90 percentile for the general population and 82.61 score for disabled adults that the similar gap in every domain, its means that there are significant functioning difference and health equality in general adults population and adults with disabilities. This presents a substantial challenge for both the government and the whole

    Studies on the association of fasting insulin concentrations or insulin resistance with subsequent risk of hypertension have yielded conflicting results. To quantitatively assess the association of fasting insulin concentrations or homeostasis model assessment insulin resistance (HOMA-IR) with incident hypertension in a general population by performing a meta-analysis. We searched the PubMed and Embase databases until August 31, 2016 for prospective observational studies investigating the elevated fasting insulin concentrations or HOMA-IR with subsequent risk of hypertension in the general population. Pooled risk ratio (RR) and 95% confidence interval (CI) of hypertension was calculated for the highest versus the lowest category of fasting insulin or HOMA-IR. Eleven studies involving 10,230 hypertension cases were identified from 55,059 participants. Meta-analysis showed that the pooled adjusted RR of hypertension was 1.54 (95% CI 1.34-1.76) for fasting insulin concentrations and 1.43 (95% CI 1.27-1.62) for HOMA-IR comparing the highest to the lowest category. Subgroup analysis results showed that the association of fasting insulin concentrations with subsequent risk of hypertension seemed more pronounced in women (RR 2.07; 95% CI 1.19-3.60) than in men (RR 1.48; 95% CI 1.17-1.88). This meta-analysis suggests that elevated fasting insulin concentrations or insulin resistance as estimated by homeostasis model assessment is independently associated with an exacerbated risk of hypertension in the general population. Early intervention of hyperinsulinemia or insulin resistance may help clinicians to identify the high risk of hypertensive population. Copyright © 2016 Elsevier B.V. All rights reserved.

    The Groningen Protocol aims at providing guidance in end-of-life decision-making for severely impaired newborns. Since its publication in 2005 many bioethicists and health care professionals have written articles in response. However, only very little is known about the opinion among the general population on this subject. The aim of this study was to present the general attitude towards neonatal euthanasia (NE) among the Austrian population and the factors associated with the respondents' opinion. A cross-sectional study was conducted among the general Austrian population. Computer-assisted telephone interviews were performed with 1,000 interviewees aged 16 years and older. Binary logistic regression was performed in order to determine factors that are independently associated with the respondents' opinion about neonatal euthanasia. While 63.6% of the participants rejected the idea of neonatal euthanasia for severely impaired newborns, 36.4% opted either in favor or were undecided. Regression analysis has shown the respondents' educational level (p = 0.005) and experience in the care of terminally ill persons (p = 0.001) to be factors that are positively associated with the rejection of neonatal euthanasia, whereas a higher age was associated with a lower degree of rejection (p = 0.021). We found that the majority of the Austrian population rejects the idea of neonatal euthanasia for severely impaired newborns. However, given the increasing levels of rejection of NE among the younger generations and among people with a higher educational level, it cannot be precluded that the rejection rate might in future increase even further, rather than decrease.

    The purpose of this study was to determine the prevalence and incidence of vestibular vertigo in the general population and to describe its clinical characteristics and associated factors. The neurotologic survey had a two-stage general population sampling design: nationwide modified random digit dialing sampling for participation in the German National Telephone Health Interview Survey 2003 (response rate 52%) with screening of a random sample of 4,869 participants for moderate or severe dizziness or vertigo, followed by detailed neurotologic interviews developed through piloting and validation (n = 1,003, response rate 87%). Diagnostic criteria for vestibular vertigo were rotational vertigo, positional vertigo, or recurrent dizziness with nausea and oscillopsia or imbalance. Vestibular vertigo was detected by our interview with a specificity of 94% and a sensitivity of 84[corrected]% in a concurrent validation study using neurotology clinic diagnoses as an accepted standard (n = 61). The lifetime prevalence of vestibular vertigo was 7.4[corrected]%, the 1-year prevalence was 4.9[corrected]%, and the incidence was 1.4[corrected]%. In 80% of affected individuals, vertigo resulted in a medical consultation, interruption of daily activities, or sick leave. Female sex, age, lower educational level, and various comorbid conditions, including tinnitus, depression, and several cardiovascular diseases and risk factors, were associated with vestibular vertigo in the past year in univariate analysis. In multivariable analysis, only female sex, self-reported depression, tinnitus, hypertension, and dyslipidemia had an independent effect on vestibular vertigo. Vestibular vertigo is common in the general population, affecting [corrected] 5% of adults in 1 year. The frequency and health care impact of vestibular symptoms at the population level have been underestimated.

    Attention-deficit/hyperactivity disorder (ADHD) can be viewed as the extreme end of traits in the general population. Epidemiological and twin studies suggest that ADHD frequently co-occurs with and shares genetic susceptibility with autism spectrum disorder (ASD) and ASD-related traits. The aims of this study were to determine whether a composite of common molecular genetic variants, previously found to be associated with clinically diagnosed ADHD, predicts ADHD and ASD-related traits in the general population. Polygenic risk scores were calculated in the Avon Longitudinal Study of Parents and Children (ALSPAC) population sample (N = 8229) based on a discovery case-control genome-wide association study of childhood ADHD. Regression analyses were used to assess whether polygenic scores predicted ADHD traits and ASD-related measures (pragmatic language abilities and social cognition) in the ALSPAC sample. Polygenic scores were also compared in boys and girls endorsing any (rating ≥ 1) ADHD item (n = 3623). Polygenic risk for ADHD showed a positive association with ADHD traits (hyperactive-impulsive, p = .0039; inattentive, p = .037). Polygenic risk for ADHD was also negatively associated with pragmatic language abilities (p = .037) but not with social cognition (p = .43). In children with a rating ≥ 1 for ADHD traits, girls had a higher polygenic score than boys (p = .003). These findings provide molecular genetic evidence that risk alleles for the categorical disorder of ADHD influence hyperactive-impulsive and attentional traits in the general population. The results further suggest that common genetic variation that contributes to ADHD diagnosis may also influence ASD-related traits, which at their extreme are a characteristic feature of ASD.

    'Food addiction' shares a similar neurobiological and behavioral framework with substance addiction. However whether, and to what degree, 'food addiction' contributes to obesity in the general population is unknown. to assess 1) the prevalence of 'food addiction' in the Newfoundland population; 2) if clinical symptom counts of 'food addiction' were significantly correlated with the body composition measurements; 3) if food addicts were significantly more obese than controls, and 4) if macronutrient intakes are associated with 'food addiction'. A total of 652 adults (415 women, 237 men) recruited from the general population participated in this study. Obesity was evaluated by Body Mass Index (BMI) and Body Fat percentage measured by dual-energy X-ray absorptiometry. 'Food addiction' was assessed using the Yale Food Addiction Scale and macronutrient intake was determined from the Willet Food Frequency Questionnaire. The prevalence of 'food addiction' was 5.4% (6.7% in females and 3.0% in males) and increased with obesity status. The clinical symptom counts of 'food addiction' were positively correlated with all body composition measurements across the entire sample (pObesity measurements were significantly higher in food addicts than controls; Food addicts were 11.7 (kg) heavier, 4.6 BMI units higher, and had 8.2% more body fat and 8.5% more trunk fat. Furthermore, food addicts consumed more calories from fat and protein compared with controls. Our results demonstrated that 'food addiction' contributes to severity of obesity and body composition measurements from normal weight to obese individuals in the general population with higher rate in women as compared to men.

    Full Text Available Background: although alcohol abuse is known to increase serum uric acid, the relation between moderate drinking and uric acid have remained poorly understood. We performed this study to evaluate whether different alcohol consumption level has different effects on the risk of hyperuricemia based on a rural general population. Method: multi-stage cluster sampling method was used to select a representative sample of individuals aged 35 years or older. Participants were asked to provide information about their alcohol consumption. Data regarding the demographic and lifestyle characteristics and the blood biochemical indexes of these participants were collected by well-trained personnel. Results: in total, 11,039 participants aged 35 years or older were included (4997 men and 6042 women. The prevalence of hyperuricemia in the different male alcohol consumption groups was 11.9% in non-drinkers, 12.6% in moderate drinkers, and 16.3% in heavy drinkers (p < 0.001. In females, the rates were 6.3% in non-drinkers, 8.1% in moderate drinkers, and 6.6% for heavy drinkers (p = 0.818. In males, multivariate logistic regression analyses shows heavy drinkers had an approximately 1.7-fold higher risk of hyperuricemia (OR: 1.657, 95% CI: 1.368 to 2.007, p < 0.001 than non-drinkers; moderate drinkers did not experience a significant increase in risk (OR: 1.232, 95% CI: 0.951 to 1.596, p = 0.114. Multivariate logistic regression analyses of females showed that, compared with non-drinkers, neither moderate nor heavy drinkers had a significantly increased risk of hyperuricemia (OR: 1.565, 95% CI: 0.521 to 4.695, p = 0.425 for heavy drinkers; OR: 0.897, 95% CI: 0.117 to 6.855, p = 0.916 for moderate drinkers. Conclusions: heavy alcohol consumption increased the risk of hyperuricemia for males but not for females. Among both males and females, moderate alcohol consumption did not increase the risk of hyperuricemia.

    There is an unmet need for general population-based epidemiological data on rosacea based on contemporary diagnostic criteria and validated population survey methodology. To evaluate the prevalence of rosacea in the general population of Germany and Russia. General population screening was conducted in 9-10 cities per country to ensure adequate geographic representation. In Part I of this two-phase study, screening of a representative sample of the general population (every fifth person or every fifth door using a fixed-step procedure on a random route sample) was expedited with use of a questionnaire and algorithm based on current diagnostic criteria for rosacea. Of the subjects that screened positive in the initial phase, a randomly selected sample (every third subject) t`hen underwent diagnostic confirmation by a dermatologist in Part II. A total of 3052 and 3013 subjects (aged 18-65 years) were screened in Germany and Russia respectively. Rosacea prevalence was 12.3% [95%CI, 10.2-14.4] in Germany and 5.0% [95%CI, 2.8-7.2] in Russia. The profile of subjects with rosacea (75% women; mean age of 40 years; mainly skin phototype II or III, majority of subjects with sensitive facial skin) and subtype distribution were similar. Overall, 18% of subjects diagnosed with rosacea were aged 18-30 years. Over 80% were not previously diagnosed. Within the previous year, 47.5% of subjects had received no rosacea care and 23.7% had received topical and/or systemic drugs. Over one-third (35% Germany, 43% Russia) of rosacea subjects reported a moderate to severe adverse impact on quality of life. Rosacea is highly prevalent in Germany (12.3%) and Russia (5.0%). The demographic profile of rosacea subjects was similar between countries and the majority were previously undiagnosed. © 2016 The Authors.

    2013-01-01

    Background The present study aimed to develop an artificial neural network (ANN) based prediction model for cardiovascular autonomic (CA) dysfunction in the general population. Methods We analyzed a previous dataset based on a population sample consisted of 2,092 individuals aged 30–80 years. The prediction models were derived from an exploratory set using ANN analysis. Performances of these prediction models were evaluated in the validation set. Results Univariate analysis indicated that 14 risk factors showed statistically significant association with CA dysfunction (P < 0.05). The mean area under the receiver-operating curve was 0.762 (95% CI 0.732–0.793) for prediction model developed using ANN analysis. The mean sensitivity, specificity, positive and negative predictive values were similar in the prediction models was 0.751, 0.665, 0.330 and 0.924, respectively. All HL statistics were less than 15.0. Conclusion ANN is an effective tool for developing prediction models with high value for predicting CA dysfunction among the general population. PMID:23902963

    Little is known about engagement in multiple health behaviours in childhood cancer survivors. Using latent class analysis, we identified health behaviour patterns in 835 adult survivors of childhood cancer (age 20-35 years) and 1670 age- and sex-matched controls from the general population. Behaviour groups were determined from replies to questions on smoking, drinking, cannabis use, sporting activities, diet, sun protection and skin examination. The model identified four health behaviour patterns: 'risk-avoidance', with a generally healthy behaviour; 'moderate drinking', with higher levels of sporting activities, but moderate alcohol-consumption; 'risk-taking', engaging in several risk behaviours; and 'smoking', smoking but not drinking. Similar proportions of survivors and controls fell into the 'risk-avoiding' (42% vs 44%) and the 'risk-taking' cluster (14% vs 12%), but more survivors were in the 'moderate drinking' (39% vs 28%) and fewer in the 'smoking' cluster (5% vs 16%). Determinants of health behaviour clusters were gender, migration background, income and therapy. A comparable proportion of childhood cancer survivors as in the general population engage in multiple health-compromising behaviours. Because of increased vulnerability of survivors, multiple risk behaviours should be addressed in targeted health interventions.

    Full Text Available Abstract Background The aim of this study was to identify factors associated with cancer screening practices and with general attitudes toward cancer screening in a general population. Methods Mailed survey of 30–60 year old residents of Geneva, Switzerland, that included questions about screening for five cancers (breast, cervix uteri, prostate, colon, skin in the past 3 years, attitudes toward screening, health care use, preventive behaviours and socio-demographic characteristics. Cancer screening practice was dichotomised as having done at least one screening test in the past 3 years versus none. Results The survey response rate was 49.3% (2301/4670. More women than men had had at least one cancer screening test in the past 3 years (83.2% vs 34.5%, p Conclusion Attitudes play an important role in cancer screening practices among middle-aged adults in the general population, independent of demographic variables (age and sex that determine in part screening recommendations. Negative attitudes were the most frequent among men and the most socio-economically disadvantaged. The moderate participation rate raises the possibility of selection bias.

    Chronic widespread pain (CWP) is a significant burden in communities. Understanding the impact of population-dependent (e.g., age, gender) and contextual-dependent (e.g. survey method, region, inequality level) factors have on CWP prevalence may provide a foundation for population-based strategies to address CWP. Therefore, the purpose of this study was to estimate the global prevalence of CWP and evaluate the population and contextual factors associated with CWP. A systematic review of CWP prevalence studies (1990-2017) in the general population was undertaken. Meta-analyses were conducted to determine CWP prevalence, and study population data and contextual factors were evaluated using a meta-regression. Thirty-nine manuscripts met the inclusion criteria. Study CWP prevalence ranged from 1.4% to 24.0%, with CWP prevalence in men ranging from 0.8% to 15.3% and 1.7% to 22.1% in women. Estimated overall CWP prevalence was 9.6% (8.0-11.2%). Meta-regression analyses showed gender, United Nations country development status, and human development index (HDI) influenced CWP prevalence, while survey method, region, methodological and reporting quality, and inequality showed no significant effect on the CWP estimate. Globally CWP affects one in ten individuals within the general population, with women more likely to experience CWP than men. HDI was noted to be the socioeconomic factor related to CWP prevalence, with those in more developed countries having a lower CWP prevalence than those in less developed countries. Most CWP estimates were from developed countries, and CWP estimates from countries with a lower socioeconomic position is needed to further refine the global estimate of CWP. This systematic review and meta-analysis updates the current global CWP prevalence by examining the population-level (e.g. age, gender) and contextual (e.g. country development status; survey style; reporting and methodologic quality) factors associated with CWP prevalence.

    Lactase persistence (LP) is a genetic trait that has been studied among different countries and ethnic groups. In Latin America, the frequencies of this trait have been shown to vary according to the degree of admixture of the populations. The objective of this study is to better understand the relationship between this genetic trait and dairy intake in a multiethnic context through a synthesis of studies conducted in four regions of Chile. Genotypes frequencies for the SNP LCT-13910C>T (rs4988235) and frequency of dairy consumption were obtained from four populations: Polynesians from Easter Island (Rapanui); Amerindians (Mapuche) and Mestizos from the Araucanía region; urban Mestizos from Santiago; and rural Mestizos from the Coquimbo region. Genetic differentiation and association between milk consumption and genotype frequencies were estimated. Genetic differentiation between Native and Mestizo populations was significant; the LP frequency in Mapuche and Rapanui was 10% and 25%, respectively, whereas among the Mestizos, LP frequency was near 40%. Dairy intake was below the nutritional recommendations for the four groups, and extremely below recommendations among the indigenous populations. Association between milk intake and LP was found in Santiago and Rapanui populations. Although the frequency of LP varies among the populations according to their degree of admixture, dairy consumption was very low across the populations. Given that the association between milk consumption and expected phenotype was found only in two of the populations analyzed, it seems that lactase non-persistence (LNP) is not the only cause for dairy avoidance. Thus, it is suggested that SES and cultural preferences are likely affecting dairy consumption. © 2015 Wiley Periodicals, Inc.

    Full Text Available Abstract Background Severe alpha1-antitrypsin (AAT deficiency associated with low AAT blood concentrations is an established genetic COPD risk factor. Less is known about the respiratory health impact of variation in AAT serum concentrations in the general population. We cross-sectionally investigated correlates of circulating AAT concentrations and its association with FEV1. Methods In 5187 adults (2669 females with high-sensitive c-reactive protein (CRP levels ≤ 10 mg/l from the population-based Swiss SAPALDIA cohort, blood was collected at the time of follow-up examination for measuring serum AAT and CRP. Results Female gender, hormone intake, systolic blood pressure, age in men and in postmenopausal women, as well as active and passive smoking were positively, whereas alcohol intake and BMI inversely correlated with serum AAT levels, independent of CRP adjustment. We observed an inverse association of AAT with FEV1 in the total study population (p Conclusion The results of this population-based study reflect a complex interrelationship between tobacco exposure, gender related factors, circulating AAT, systemic inflammatory status and lung function.

    Water balance is achieved when water intake from solid and fluid foods and drinking water meets water losses, mainly in sweat, urine and faeces. Seasonality, particularly in Mediterranean countries that have a hot summer, may affect water loss and consequently water balance. Water balance has not been estimated before on a population level and the effect of seasonality has not been evaluated. The present study aimed to compare water balance, intake and loss in summer and winter in a sample of the general population in Greece. The Water Balance Questionnaire (WBQ) was used to evaluate water balance, estimating water intake and loss in summer (n = 480) and in winter (n = 412) on a stratified sample of the general population in Athens, Greece. In winter, mean (SD) water balance was -63 (1478) mL/day(-1) , mean (SD)water intake was 2892 (987) mL/day(-1) and mean (quartile range) water loss was 2637 (1810-3922) mL/day(-1) . In summer, mean (SD) water balance was -58 (2150) mL/day(-1) , mean (SD) water intake was 3875 (1373) mL/day(-1) and mean (quartile range) water loss was 3635 (2365-5258) mL/day(-1) . Water balance did not differ between summer and winter (P = 0.96); however, the data distribution was different; in summer, approximately 8% more participants were falling in the low and high water balance categories. Differences in water intake from different sources were identified (P balance in summer and winter was not different. However, water intake and loss were approximately 40% higher in summer than in winter. More people were falling in the low and high water balance categories in summer when comparing the distribution on water balance in winter. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

    Numerous studies have investigated the prevalence and risk factors of hand eczema in the general population. These studies are of high value as they tend to be less biased than studies using clinical populations and as they are important for healthcare decision makers when they allocate resources......-year prevalence nearly 10%, whereas the lifetime prevalence reached 15%. Based on seven studies, the median incidence rate of hand eczema was 5.5 cases/1000 person-years (women = 9.6 and men = 4.0). A high incidence rate was associated with female sex, contact allergy, atopic dermatitis, and wet work....... Atopic dermatitis was the single most important risk factor for hand eczema. Hand eczema resulted in medical consultations in 70%, sick leave (> 7 days) in about 20%, and job change in about 10%. Mean sick time was longer among those with allergic hand eczema than those with atopic and irritant hand...

    Helicobacter pylori (H.pylori) infection is probably the most important factor that has been associated with the development of gastric cancers in human populations. However, there are no reliable data on the prevalence of this infection in the Middle East. In this article, based on a comprehensive literature review, we aimed to evaluate the situation in this region. The literature has been searched for the incidence and prevalence of H.pylori infection by Pubmed and Google Scholar. Search was repeated for each of the Middle Eastern countries, and to empower the method, citations of each found article were searched for the related studies. Seventy seven reports from the countries of the Middle East region had been reviewed and they all indicated a high rate of infection either in the general population or in the dyspeptic patients, the rate seemed to be higher in patients with dyspepsia, in patients with histologically confirmed gastritis and in patients of older age groups.

    OBJECTIVE: Chemerin has been found to be highly expressed in the kidneys of rodents and has been suggested to affect metabolic syndrome (MetS)-related phenotypes which are in turn related to kidney damage. Only few clinical studies have addressed the relation between circulating chemerin and renal...... function in humans, and no population-based analyses have yet been performed. The potential influence of MetS-related phenotypes on the assumed association has been largely neglected. We aimed to investigate the association of serum chemerin with renal function in a general population with special regard......GFR and revealed that each increase in chemerin per 25 ng/mL was associated with an about threefold higher odds of chronic kidney disease [odds ratio 2.72 (95% confidence interval 2.26-3.29)]. CONCLUSIONS: Our results demonstrate a strong inverse association between serum chemerin levels and renal function...

    Prediction algorithms are useful for making clinical decisions and for population health planning. However, such prediction algorithms for first onset of major depression do not exist. The objective of this study was to develop and validate a prediction algorithm for first onset of major depression in the general population. Longitudinal study design with approximate 3-year follow-up. The study was based on data from a nationally representative sample of the US general population. A total of 28 059 individuals who participated in Waves 1 and 2 of the US National Epidemiologic Survey on Alcohol and Related Conditions and who had not had major depression at Wave 1 were included. The prediction algorithm was developed using logistic regression modelling in 21 813 participants from three census regions. The algorithm was validated in participants from the 4th census region (n=6246). Major depression occurred since Wave 1 of the National Epidemiologic Survey on Alcohol and Related Conditions, assessed by the Alcohol Use Disorder and Associated Disabilities Interview Schedule-diagnostic and statistical manual for mental disorders IV. A prediction algorithm containing 17 unique risk factors was developed. The algorithm had good discriminative power (C statistics=0.7538, 95% CI 0.7378 to 0.7699) and excellent calibration (F-adjusted test=1.00, p=0.448) with the weighted data. In the validation sample, the algorithm had a C statistic of 0.7259 and excellent calibration (Hosmer-Lemeshow χ(2)=3.41, p=0.906). The developed prediction algorithm has good discrimination and calibration capacity. It can be used by clinicians, mental health policy-makers and service planners and the general public to predict future risk of having major depression. The application of the algorithm may lead to increased personalisation of treatment, better clinical decisions and more optimal mental health service planning.

    Full Text Available Objective. Aldosterone and high-density lipoprotein cholesterol (HDL-C are involved in many pathophysiological processes that contribute to the development of cardiovascular diseases. Previously, associations between the concentrations of aldosterone and certain components of the lipid metabolism in the peripheral circulation were suggested, but data from the general population is sparse. We therefore aimed to assess the associations between aldosterone and HDL-C, low-density lipoprotein cholesterol (LDL-C, total cholesterol, triglycerides, or non-HDL-C in the general adult population. Methods. Data from 793 men and 938 women aged 25–85 years who participated in the first follow-up of the Study of Health in Pomerania were obtained. The associations of aldosterone with serum lipid concentrations were assessed in multivariable linear regression models adjusted for sex, age, body mass index (BMI, estimated glomerular filtration rate (eGFR, and HbA1c. Results. The linear regression models showed statistically significant positive associations of aldosterone with LDL-C (β-coefficient = 0.022, standard error = 0.010, p=0.03 and non-HDL-C (β-coefficient = 0.023, standard error = 0.009, p=0.01 as well as an inverse association of aldosterone with HDL-C (β-coefficient = −0.022, standard error = 0.011, p=0.04. Conclusions. The present data show that plasma aldosterone is positively associated with LDL-C and non-HDL-C and inversely associated with HDL-C in the general population. Our data thus suggests that aldosterone concentrations within the physiological range may be related to alterations of lipid metabolism.

    The purpose of this study was to assess whether pregnant smokers have the same nicotine intake from cigarettes as a general population of smokers and whether the known lower daily cigarette consumption among pregnant smokers is associated with higher nicotine intake among pregnant smokers. The study was a cross-sectional comparison of pregnant smokers and a general population of smokers in smoking cessation clinics. Participants were treatment-seeking pregnant (n = 476), nonpregnant female (n = 116), and male (n = 195) smokers who participated in two independent smoking cessation trials. Nicotine intake was measured as saliva cotinine/ cigarette/kg body weight ratio. The mean saliva cotinine (μg/L)/ cigarette/kg body weight (0.21, SD = 0.15) of pregnant smokers was similar to that of nonpregnant female smokers (0.24, SD = 0.14) and higher than that of male smokers (0.18, SD = 0.12, p = .002) despite a substantially lower number of cigarettes per day (pregnant smokers: 12, SD = 6; nonpregnant female smokers: 26.6, SD = 11.7; male smokers: 23.5, SD = 9.5, p smokers, saliva cotinine, as expected, increased in parallel with the number of cigarettes per day, but nicotine intake (cotinine/cigarette/kg body weight) was inversely associated with daily cigarette consumption (p smokers (p = .43). This secondary analysis showed that pregnant smokers' nicotine intake was similar to that of a general population of smokers despite a lower cigarette consumption rate. Among pregnant smokers, lower daily cigarette consumption was associated with higher nicotine intake from cigarettes, suggesting compensatory smoking.

  8. Proton Pump Inhibitor Usage and the Risk of Myocardial Infarction in the General Population.

    Full Text Available Proton pump inhibitors (PPIs have been associated with adverse clinical outcomes amongst clopidogrel users after an acute coronary syndrome. Recent pre-clinical results suggest that this risk might extend to subjects without any prior history of cardiovascular disease. We explore this potential risk in the general population via data-mining approaches.Using a novel approach for mining clinical data for pharmacovigilance, we queried over 16 million clinical documents on 2.9 million individuals to examine whether PPI usage was associated with cardiovascular risk in the general population.In multiple data sources, we found gastroesophageal reflux disease (GERD patients exposed to PPIs to have a 1.16 fold increased association (95% CI 1.09-1.24 with myocardial infarction (MI. Survival analysis in a prospective cohort found a two-fold (HR = 2.00; 95% CI 1.07-3.78; P = 0.031 increase in association with cardiovascular mortality. We found that this association exists regardless of clopidogrel use. We also found that H2 blockers, an alternate treatment for GERD, were not associated with increased cardiovascular risk; had they been in place, such pharmacovigilance algorithms could have flagged this risk as early as the year 2000.Consistent with our pre-clinical findings that PPIs may adversely impact vascular function, our data-mining study supports the association of PPI exposure with risk for MI in the general population. These data provide an example of how a combination of experimental studies and data-mining approaches can be applied to prioritize drug safety signals for further investigation.

    Full Text Available Haptoglobin is a plasma hemoglobin-binding protein that limits iron loss during normal erythrocyte turnover and hemolysis, thereby preventing oxidative damage mediated by iron excess in the circulation. Haptoglobin polymorphism in humans, characterized by the Hp*1 and Hp*2 alleles, results in distinct phenotypes known as Hp1-1, Hp2-1 and Hp2-2, whose frequencies vary according to the ethnic origin of the population. The Hp*1 allele has two subtypes, Hp*1F and Hp*1S, that also vary in their frequencies among populations worldwide. In this work, we examined the distribution frequencies of haptoglobin subtypes in three Brazilian population groups of different ethnicities. The haptoglobin genotypes of Kayabi Amerindians (n = 56, Kalunga Afro-descendants (n = 70 and an urban population (n = 132 were determined by allele-specific PCR. The Hp*1F allele frequency was highest in Kalunga (29.3% and lowest in Kayabi (2.6%. The Hp*1F/Hp*1S allele frequency ratios were 0.6, 1.0 and 0.26 for the Kayabi, Kalunga and urban populations, respectively. This variation was attributable largely to the Hp*1F allele. However, despite the large variation in Hp*1F frequencies, results of FST (0.0291 indicated slight genetic differentiation among subpopulations of the general Brazilian population studied here. This is the first Brazilian report of variations in the Hp *1F and Hp*1S frequencies among non-Amerindian Brazilians.

    Insufficient sleep duration and obstructive sleep apnea, two common causes of sleep deficiency in adults, can result in excessive sleepiness, a well-recognized cause of motor vehicle crashes, although their contribution to crash risk in the general population remains uncertain. The objective of this study was to evaluate the relation of sleep apnea, sleep duration, and excessive sleepiness to crash risk in a community-dwelling population. This was a prospective observational cohort study nested within the Sleep Heart Health Study, a community-based study of the health consequences of sleep apnea. The participants were 1745 men and 1456 women aged 40-89 years. Sleep apnea was measured by home polysomnography and questionnaires were used to assess usual sleep duration and daytime sleepiness. A follow-up questionnaire 2 years after baseline ascertained driving habits and motor vehicle crash history. Logistic regression analysis was used to examine the relation of sleep apnea and sleep duration at baseline to the occurrence of motor vehicle crashes during the year preceding the follow-up visit, adjusting for relevant covariates. The population-attributable fraction of motor vehicle crashes was estimated from the sample proportion of motor vehicle crashes and the adjusted odds ratios for motor vehicle crash within each exposure category. Among 3201 evaluable participants, 222 (6.9%) reported at least one motor vehicle crash during the prior year. A higher apnea-hypopnea index (p vehicle crashes was 10% due to sleep apnea and 9% due to sleep duration less than 7 hours. Sleep deficiency due to either sleep apnea or insufficient sleep duration is strongly associated with motor vehicle crashes in the general population, independent of self-reported excessive sleepiness.

    Full Text Available Abstract Background The objective of this study was to systematically review the medical literature for the prevalence of waterpipe tobacco use among the general and specific populations. Methods We electronically searched MEDLINE, EMBASE, and the ISI the Web of Science. We selected studies using a two-stage duplicate and independent screening process. We included cohort studies and cross sectional studies assessing the prevalence of use of waterpipe in either the general population or a specific population of interest. Two reviewers used a standardized and pilot tested form to collect data from each eligible study using a duplicate and independent screening process. We stratified the data analysis by country and by age group. The study was not restricted to a specific context. Results Of a total of 38 studies, only 4 were national surveys; the rest assessed specific populations. The highest prevalence of current waterpipe smoking was among school students across countries: the United States, especially among Arab Americans (12%-15% the Arabic Gulf region (9%-16%, Estonia (21%, and Lebanon (25%. Similarly, the prevalence of current waterpipe smoking among university students was high in the Arabic Gulf region (6%, the United Kingdom (8%, the United States (10%, Syria (15%, Lebanon (28%, and Pakistan (33%. The prevalence of current waterpipe smoking among adults was the following: Pakistan (6%, Arabic Gulf region (4%-12%, Australia (11% in Arab speaking adults, Syria (9%-12%, and Lebanon (15%. Group waterpipe smoking was high in Lebanon (5%, and Egypt (11%-15%. In Lebanon, 5%-6% pregnant women reported smoking waterpipe during pregnancy. The studies were all cross-sectional and varied by how they reported waterpipe smoking. Conclusion While very few national surveys have been conducted, the prevalence of waterpipe smoking appears to be alarmingly high among school students and university students in Middle Eastern countries and among groups of

    Women living with HIV (WLWH) are at increased risk of invasive cervical cancer (ICC). International HIV guidelines suggest cervical screening twice the first year after HIV diagnosis and thereafter annually. Adherence to the HIV cervical screening program in Denmark is unknown. We studied women from a population-based, nationwide HIV cohort in Denmark and a cohort of age-matched females from the general population. Screening behaviour was assessed from 1999-2010. Adjusted odds ratios (OR's) for screening attendance in the two cohorts and potential predictors of attendance to guidelines were estimated. Pathology specimens were identified from The Danish Pathology Data Bank. We followed 1143 WLWH and 17,145 controls with no prior history of ICC for 9,509 and 157,362 person-years. The first year after HIV diagnosis 2.6% of WLWH obtained the recommended two cervical cytologies. During the different calendar intervals throughout the study period between 29-46% of WLWH followed the HIV cervical screening guidelines. Adjusted OR's of attendance to the general population screening program for WLWH aged 30, 40 and 50 years, compared to controls, were 0.69 (95% CI: 0.56-0.87), 0.67 (0.55-0.80) and 0.84 (0.61-1.15). Predictors of attendance to the HIV cervical screening program were a CD4 count > 350 cells/μL and HIV RNA < 500 copies/mL. Calendar period after 2002 and HIV RNA < 500 copies/mL predicted attendance to the general population cervical screening program. The majority of WLWH do not follow the HIV guidelines for cervical screening. We support the idea of cytology as part of an annual review and integration of HIV care and cervical screening in a single clinic setting.

    Contact allergy to fragrances is assessed mostly in clinical populations of patients. Studies in the general population are scarce and vary in their methodology across countries. To determine the prevalence of fragrance contact allergy in the European general population and to assess the clinical relevance of positive patch test reactions to different fragrances. In five European countries (Germany, Italy, the Netherlands, Portugal and Sweden) a random sample from the general population aged 18-74 years was drawn. In total, 12 377 subjects were interviewed in this cross-sectional study and a random sample (n = 3119) was patch tested using the TRUE Test and Finn Chamber techniques. Patch test procedures were harmonized by mandatory training before the study and monitoring during the study. The highest prevalence for contact allergy of 2·6% [95% confidence interval (CI) 2·1-3·2] was found for fragrance mix (FM) I in petrolatum, with a high content of atranol and chloratranol, followed by 1·9% (95% CI 1·5-2·4) for FM II in petrolatum. The conservatively estimated prevalence of fragrance contact allergy was 1·9% (95% CI 1·5-2·5). This is defined as the existence of a positive patch test to FM I or FM II; any of their individual materials; Myroxylon pereirae; sesquiterpene lactones or 3- and 4-hydroxyisohexyl 3-cyclohexene carboxaldehyde that show clinical relevance, defined conservatively as lifetime avoidance of scented products and an itchy skin rash lasting > 3 days in a lifetime. Using the reported lifetime prevalence of any contact dermatitis instead of the lifetime prevalence of any itchy skin rash, the prevalence is 0·8% (95% CI 0·5-1·2). The prevalence rates of contact allergy to fragrances in women are about twice those in men. This study helps to identify targets for prevention of fragrance allergy. © 2015 British Association of Dermatologists.

    Personal factors, especially attitude, have been implicated in the utilization of health care services, and in access to medical treatment. There is little information on the attitudes of the general public in South Africa towards medications and whether attitudes differ across population groups or among the different users of the health care system. This study aimed to determine the general attitude of a local population to medications, self-care orientation and health professional contact, and whether differences existed between age groups, gender and race groups. METHODS We carried out a randomized, cross-sectional quantitative study via telephonic questionnaire survey (adapted from a previous study) of a sample of 1132 telephone numbers. The setting was the Durban Metropolitan Area, KwaZulu-Natal, South Africa. KEY FINDINGS A total of 500 (44.2%) people responded. The majority had a positive attitude towards medication. An increase in age resulted in increased medication use. Females were more likely than males to use medication and seek professional health care (P = 0.0406). Most of the respondents (86.0%) were self-care-orientated and displayed moderate medication knowledge (46.2%). Some 295 (59.0%) of the 500 respondents had visited a pharmacy within the last 6 months. Conclusions Health care professionals can adopt an informed approach to address the needs of the population with regard to medication, by targeting groups more likely to use medication (females and the older age group). In addition, gaps in medication knowledge were identified which could be used for health-promotion interventions by health care workers.

    Background Health care is increasingly featured by the use of Web 2.0 communication and collaborative technologies that are reshaping the way patients and professionals interact. These technologies or tools can be used for a variety of purposes: to instantly debate issues, discover news, analyze research, network with peers, crowd-source information, seek support, and provide advice. Not all tools are implemented successfully; in many cases, the nonusage attrition rates are high. Little is known about the preferences of the Dutch general population regarding the use of the Internet and social media in health care. Objective To determine the preferences of the general population in the Netherlands regarding the use of the Internet and social media in health care. Methods A cross-sectional survey was disseminated via a popular Dutch online social network. Respondents were asked where they searched for health-related information, how they qualified the value of different sources, and their preferences regarding online communication with health care providers. Results were weighed for the Dutch population based on gender, age, and level of education using official statistics. Numbers and percentages or means and standard deviations were presented for different subgroups. One-way ANOVA was used to test for statistical differences. Results The survey was completed by 635 respondents. The Internet was found to be the number one source for health-related information (82.7%), closely followed by information provided by health care professionals (71.1%). Approximately one-third (32.3%) of the Dutch population search for ratings of health care providers. The most popular information topics were side effects of medication (62.5%) and symptoms (59.7%). Approximately one-quarter of the Dutch population prefer to communicate with a health care provider via social media (25.4%), and 21.2% would like to communicate via a webcam.

    Getting insufficient sleep has serious consequences in terms of mental and physical health. The current study is the first to approach insufficient sleep from a self-regulation perspective by investigating the phenomenon of bedtime procrastination: going to bed later than intended, without having external reasons for doing so. Data from a representative sample of Dutch adults (N = 2431) revealed that a large proportion of the general population experiences getting insufficient sleep and regularly goes to bed later than they would like to. Most importantly, a relationship between self-regulation and experienced insufficient sleep was found, which was mediated by bedtime procrastination. © The Author(s) 2014.

    Lack of monoamine oxidase A (MAO-A) due to either Xp chromosomal deletions or alterations in the coding sequence of the gene for this enzyme are associated with marked changes in monoamine metabolism and appear to be associated with variable cognitive deficits and behavioral changes in humans and in transgenic mice. In mice, some of the most marked behavioral changes are ameliorated by pharmacologically-induced reductions in serotonin synthesis during early development, raising the question of possible therapeutic interventions in humans with MAO deficiency states. At the present time, only one multi-generational family and a few other individuals with marked MAO-A deficiency states have been identified and studied in detail. Although MAO deficiency states associated with Xp chromosomal deletions were identified by distinct symptoms (including blindness in infancy) produced by the contiguous Norrie disease gene, the primarily behavioral phenotype of individuals with the MAO mutation is less obvious. This paper reports a sequential research design and preliminary results from screening several hundred volunteers in the general population and from putative high-risk groups for possible MAO deficiency states. These preliminary results suggest that marked MAO deficiency states are very rare.

    Despite the general agreement that normal jealousy is heterogenous, little is known about this specific topic. In the present study, we explored the possibility of distinguishing between four subtypes of "normal" jealousy (depressive, anxious, obsessive, and paranoid) amongst a cohort of 500 healthy university students by means of a specifically designed questionnaire, "Ouestionario della gelosia" (QUEGE). QUEGE is a self-report instrument of 30 items which explores the presence, frequency, and duration of feelings and behaviors related to jealousy. It was devised to investigate four hypothetical psychopathological profiles: depressive, paranoid, obsessive, and anxious. The factor analysis identified five rather than four clear-cut factors: self-esteem, paranoia, interpersonal Sensitivity, fear of being abandoned, and obsessionality. Women showed statistically significant lower levels of self-esteem and higher levels of obsessionality than men. Younger age (jealousy phenomenon in the general population.

    Onset of social phobia (SP) typically occurs in adolescence. Short screening instruments for its assessment are needed for use in primary health and school settings. The 3-item Mini-Social Phobia Inventory (SPIN) has demonstrated effectiveness in screening for generalized SP (GSP) in adults. This study examined the psychometrics of the Mini-SPIN in an adolescent general population sample. Three hundred fifty adolescents aged 12 to 17 years were clinically interviewed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version for identification of SP and other Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Axis I disorders, blind to their Mini-SPIN status. Associations between SP; subclinical SP; other anxiety, depressive, and disruptive disorders; and Mini-SPIN scores were examined, and diagnostic efficiency statistics were calculated. The association between Mini-SPIN scores and the generalized subtype of SP was also examined. As in adults, the Mini-SPIN items differentiated subjects with SP from those without. A score of 6 points or greater was found optimal in predicting SP with a sensitivity of 86%, specificity of 84%, and positive and negative predictive values of 26% and 99%. The Mini-SPIN also possessed discriminative validity, as scores were higher for adolescents with SP than they were for those with depressive, disruptive, and other anxiety disorders. The Mini-SPIN was also able to differentiate adolescents with GSP from the rest of the sample. The Mini-SPIN has good psychometrics for screening SP in adolescents from general population and may have value in screening for GSP. Copyright © 2012 Elsevier Inc. All rights reserved.

    Objective: To investigate the HCV infection rate and the route of transmission among different population groups in Eastern Gruangdong province. Methods: Anti HCV was detected with EL ISA and HCV-RNA with FQ-PCR in selected population groups in Eastern Guangdong (total 8990 subjects). Results: The anti-HCV positive rates for general population, pregnant women, medical personnel, hepatitis B patients and patients on hemodialysis (HD) were: 0.89%(58/6468), 0.93%(17/1836), 2.93%(5/171), 11.5%(47/410) and 51.4%(54/105) respectively. Twelve of the 17 anti-HCV positive mothers were found to be HCV-RNA positive and two of the 12 infants were also HCV-RNA positive: a mother-to-infant transmission rate of 16.7%. In MD patients, anti HCV positive rate in those with history of transfusion and those without transfusion was 58% and 17% respectively, the difference being significant (P<0.01). Conclusion: Blood transmission was the main route for HCV infection transmission and mother-to-infant transmission as well as infections in medical personnel should be of great concern. (authors)

    Full Text Available The purpose of the present study was to determine the prevalence of dietary supplements (DS’s and sport nutrition product (SNPs among the general population, to identify differences for gender, age, and exercise frequency, and to determine the main reasons for use. The study was designed as a web-based questionnaire in a representative sample (n = 1544 of the Dutch population. Sixty-two percent (n = 957 of the respondents reported having used DS’s, SNPs, or both in the last twelve months. Women and older people reported the highest DS use. The highest use of SNPs was reported by regular exercising men and younger people with improving sporting performance as their main objective. Most frequently reported DS’s were multivitamins (28% and vitamin C (19%—for SNPs, energy drinks (22% and isotonic drinks (19%. Health considerations were the most important motivation (DS’s 90% and SNPs 52%, but also performance was substantially reported (DS’s 14% and SNPs 35%. A substantial group of sedentary respondents also reported the use of SNPs. This study confirms that DS’s, SNPs, or both are widely used among the general population. Both health as performance are important reasons for use. It can be questioned whether the use of SNPs fits all respondents’ physical activity needs.

    Full Text Available Introduction: Single-nucleotide polymorphisms (SNPs in interleukin 1β (IL-1β gene have been known to be associated with increased susceptibility to chronic periodontitis among various ethnic populations. SNPs are more commonly observed at loci + 3954 and − 511. The aim of this study was to evaluate the role of IL-1β gene polymorphism at loci +3954 and − 511, and its association with severe chronic generalized periodontitis among the ethnic Malay, Chinese, and Indians within the Malaysian population. Materials and Methods: Saliva samples from 120 subjects (60 cases and 60 controls in the age group of 25–50 years were collected for isolation of genetic material using Norgen technique. Clinical attachment loss of ≥5 mm was considered as severe chronic generalized periodontitis. SNP's at loci +3954 and − 511 were identified and analyzed using Kompetitive Allele Specific Polymerase Chain Reaction Genotyping System (KASP™. Differences in the allele/genotype frequencies were assessed by Chi-square test (P < 0.05. Results: On the comparison between cases and controls of IL-1β genotype polymorphism (+3954 and − 511, the difference in the genotype frequencies was statistically insignificant in all the three ethnicities. The genotype frequency in both groups in all three ethnicities of the Malaysian population was similar. Conclusion: IL-1β genotype polymorphism at +3954 and − 511 was found to be not associated with severe chronic generalized periodontitis among the three ethnicities in Malaysia. Studies with larger sample size should be done to confirm the findings of this study.

    Little is known about cultural differences in the expression of distress in anxiety disorders. Previous cross-cultural studies of depression have found a greater somatic focus in Asian populations. We examined anxiety symptoms in patients with generalized anxiety disorder (GAD) in urban mental health settings in Nepal (N = 30) and in the United States (N = 23). Participants completed the Beck Anxiety Inventory (BAI). The overall BAI score and somatic and psychological subscales were compared. While there was no difference in total BAI scores, the Nepali group scored higher on the somatic subscale (i.e. "dizziness" and "indigestion," t[df] = -2.63[50], p < 0.05), while the American group scored higher on the psychological subscale (i.e. "scared" and "nervous," t[df] = 3.27[50], p < 0.01). Nepali patients with GAD had higher levels of somatic symptoms and lower levels of psychological symptoms than American patients with GAD. Possible explanations include differences in cultural traditions of describing distress and the mind-body dichotomy.

    Full Text Available Abstract Background The global burden of the major vascular diseases is projected to rise and to remain the dominant non-communicable disease cluster well into the twenty first century. The Department of Health in England has developed the NHS Health Check service as a policy initiative to reduce population vascular disease risk. The aims of this study were to monitor population changes in cardiovascular disease (CVD risk factors over the first year of the new service and to assess the value of tailored lifestyle support, including motivational interview with ongoing support and referral to other services. Methods Randomised trial comparing NHS Health Check service only with NHS Health Check service plus additional lifestyle support in Stoke on Trent, England. Thirty eight general practices and 601 (365 usual care, 236 additional lifestyle support patients were recruited and randomised independently between September 2009 and February 2010. Changes in population CVD risk between baseline and one year follow-up were compared, using intention-to-treat analysis. The primary outcome was the Framingham 10 year CVD risk score. Secondary outcomes included individual modifiable risk measures and prevalence of individual risk categories. Additional lifestyle support included referral to a lifestyle coach and free sessions as needed for: weight management, physical activity, cook and eat and positive thinking. Results Average population CVD risk decreased from 32.9% to 29.4% (p Conclusions The NHS Health Check service in Stoke on Trent resulted in significant reduction in estimated population CVD risk. There was no evidence of further benefit of the additional lifestyle support services in terms of absolute CVD risk reduction.

    The article deals with analysis of national and international publications concerning methodological aspects of elaborating systematic approach to healthy life-style of population. This scope of inquiry plays a key role in development of human capital. The costs related to healthy life-style are to be considered as personal investment into future income due to physical incrementation of human capital. The definitions of healthy life-style, its categories and supportive factors are to be considered in the process of development of strategies and programs of healthy lifestyle. The implementation of particular strategies entails application of comprehensive information and educational programs meant for various categories of population. Therefore, different motivation techniques are to be considered for children, adolescents, able-bodied population, the elderly. This approach is to be resulted in establishing particular responsibility for national government, territorial administrations, health care administrations, employers and population itself. The necessity of complex legislative measures is emphasized. The recent social hygienic studies were focused mostly on particular aspects of development of healthy life-style of population. Hence, the demand for long term exploration of development of organizational and functional models implementing medical preventive measures on the basis of comprehensive information analysis using statistical, sociological and professional expertise.

    Full Text Available CONTEXT: From one country to another, the pay-for-performance mechanisms differ on one significant point: the identification of target populations, that is, populations which serve as a basis for calculating the indicators. The aim of this study was to compare clinical versus medication-based identification of populations of patients with diabetes and hypertension over the age of 50 (for men or 60 (for women, and any consequences this may have on the calculation of P4P indicators. METHODS: A comparative, retrospective, observational study was carried out with clinical and prescription data from a panel of general practitioners (GPs, the Observatory of General Medicine (OMG for the year 2007. Two indicators regarding the prescription for statins and aspirin in these populations were calculated. RESULTS: We analyzed data from 21.690 patients collected by 61 GPs via electronic medical files. Following the clinical-based approach, 2.278 patients were diabetic, 8,271 had hypertension and 1.539 had both against respectively 1.730, 8.511 and 1.304 following the medication-based approach (% agreement = 96%, kappa = 0.69. The main reasons for these differences were: forgetting to code the morbidities in the clinical approach, not taking into account the population of patients who were given life style and diet rules only or taking into account patients for whom morbidities other than hypertension could justify the use of antihypertensive drugs in the medication-based approach. The mean (confidence interval per doctor was 33.7% (31.5-35.9 for statin indicator and 38.4% (35.4-41.4 for aspirin indicator when the target populations were identified on the basis of clinical criteria whereas they were 37.9% (36.3-39.4 and 43.8% (41.4-46.3 on the basis of treatment criteria. CONCLUSION: The two approaches yield very "similar" scores but these scores cover different realities and offer food for thought on the possible usage of these indicators in the

    Full Text Available Public attitudes to mental illness could influence how the public interact with, provide opportunities for, and help people with mental illness.This study aims to explore the underlying factors of the Attitudes to Mental Illness questionnaire among the general population in Singapore and the socio-demographic correlates of each factor.From March 2014 to April 2015, a nation-wide cross-sectional survey on mental health literacy with 3,006 participants was conducted in Singapore.Factor analysis revealed a 4-factor structure for the Attitudes to Mental Illness questionnaire among the Singapore general population, namely social distancing, tolerance/support for community care, social restrictiveness, and prejudice and misconception. Older age, male gender, lower education and socio-economic status were associated with more negative attitudes towards the mentally ill. Chinese showed more negative attitudes than Indians and Malays (except for prejudice and misconception.There is a need for culture-specific interventions, and the associated factors identified in this study should be considered for future attitude campaigns.

    Public attitudes to mental illness could influence how the public interact with, provide opportunities for, and help people with mental illness. This study aims to explore the underlying factors of the Attitudes to Mental Illness questionnaire among the general population in Singapore and the socio-demographic correlates of each factor. From March 2014 to April 2015, a nation-wide cross-sectional survey on mental health literacy with 3,006 participants was conducted in Singapore. Factor analysis revealed a 4-factor structure for the Attitudes to Mental Illness questionnaire among the Singapore general population, namely social distancing, tolerance/support for community care, social restrictiveness, and prejudice and misconception. Older age, male gender, lower education and socio-economic status were associated with more negative attitudes towards the mentally ill. Chinese showed more negative attitudes than Indians and Malays (except for prejudice and misconception). There is a need for culture-specific interventions, and the associated factors identified in this study should be considered for future attitude campaigns.

    The serum resistin level is associated with the incidence of ischemic heart disease in the general population. We analyzed the associations between serum resistin and fat intake, serum lipid concentrations and adiposity in the general population. A cross-sectional study of 6,637 randomly recruited adults was conducted. The resistin levels were measured in thawed aliquots of serum using an enzyme immunoanalysis technique. The resistin level exhibited a positive nonparametric correlation with saturated fat intake(p correlation with adherence to the Mediterranean diet(p HDL cholesterol(p body mass index(p HDL cholesterol level(OR=0.84 CI95%= 0.76-0.93), a high non-HDL cholesterol level(OR=0.84 CI95%=0.72-0.99), a high LDL cholesterol level(OR=0.82 CI95%=0.70-0.97) and a waist/height ratio of ≥0.55(OR=0.76 CI95%=0.67-0.85). The multivariate models corroborated the positive associations between the resistin level and saturated fat intake(p adiposity.

    To investigate the relationship between unhealthy lifestyles factors and depressive symptoms among the general adult population in Japan. Participants were randomly selected from the Japanese general adult population. Data from 2334 people aged 20 years or older were analyzed. This cross-sectional survey was conducted in August and September 2009. Participants completed a face-to-face interview about unhealthy lifestyle factors, including lack of exercise, skipping breakfast, a poorly balanced diet, snacking between meals, insufficient sleep, current smoking, alcohol drinking, and obesity. Presence of depressive symptoms was defined as a score of ≥ 16 on the Japanese version of the Center for Epidemiologic Studies Depression Scale (CES-D). Relationships between unhealthy lifestyle factors and depressive symptoms were evaluated by multivariate logistic regression analysis adjusting for sociodemographic variables and other unhealthy lifestyle factors. Multivariate logistic regression analysis revealed that insufficient sleep, a poorly balanced diet, snacking between meals and lack of exercise were significantly associated with the prevalence of depressive symptoms, with odds ratios ranging from 1.56 for lack of exercise to 3.98 for insufficient sleep. Since this study was a cross-sectional study, causal relationships could not be determined. These results suggest that promoting a healthy lifestyle focused on sleep, food intake and exercise may be important for individuals with depressive symptoms. Copyright © 2018 Elsevier B.V.

    Although effective treatment is available for a variety of mental disorders, the treatment and help-seeking gap remains high. One of the main obstacles to help-seeking behaviour is prevailing stigmatizing attitudes. To examine attitudes within the general population towards seeking professional help in times of mental distress. A representative general population survey ( N = 594) was conducted in Slovenia by means of an Internet-based questionnaire, covering data on demographic variables and attitudes towards help-seeking behaviour. More stigmatizing attitudes towards help-seeking behaviour were found in men, single persons, those of a younger age and lower educational achievement and in respondents coming from regions with a high suicide rate. Furthermore, 52.50% of the total sample have had an experience with psychological problems, yet only 41.50% of those have sought professional help. Experience with help-seeking behaviour in the past was associated with less stigmatizing attitudes. Knowledge and understanding of mental health problems are necessary prerequisites to seeking help, but not the only ones. To improve help-seeking behaviour, it is also important to combat stigmatizing attitudes. Additionally, destigmatizing campaigns should also focus on social norms.

    Physicians in Taiwan have a heavy workload and a stressful workplace, both of which may contribute to cardiovascular disease. However, the risk of acute myocardial infarction (AMI) in physicians is not clear. This population-based cohort study used Taiwan's National Health Insurance Research Database. We identified 28,062 physicians as the case group and randomly selected 84,186 nonmedical staff patients as the control group. We used a conditional logistic regression to compare the AMI risk between physicians and controls. Subgroup analyses of physician specialty, age, gender, comorbidities, area, and hospital level were also done. Physicians have a higher prevalence of HTN (23.59% versus 19.06%, P Taiwan's physicians had higher prevalences of HTN and hyperlipidemia, but a lower risk of AMI than did the general population. Medical center physicians had a lower risk than did local clinic physicians. Physicians are not necessary healthier than the general public, but physicians, especially in medical centers, have a greater awareness of disease and greater access to medical care, which permits timely treatment and may prevent critical conditions such as AMI induced by delayed treatment.

    Social anxiety is characterized by the experience of stress, discomfort and fear in social situations, and is associated with substantial personal and societal burden. Two questionnaires exist that assess the aspects of social anxiety, i.e. social interaction anxiety (SIAS) and social phobia (SPS). There is no agreement in literature on the dimensionality of social anxiety. Further, the length of a questionnaire may negatively affect response rates and participation at follow-up occasions. To explore the structure of social anxiety in the general population, and to examine psychosocial and sociodemographic correlates. Our second aim was to construct abbreviated versions of SIAS and SPS that can be easily used and with minimal burden. A total of 1598 adults from the general Dutch population completed a survey asking information on social anxiety, mood and demographics. Exploratory and confirmatory factor analyses as well as reliability analysis with item-total statistics were performed. Confirmatory factor analysis revealed a 3-factor structure for social phobia, and a 2-factor structure for the SIAS, with the second factor containing both reversely scored items. The abbreviated versions of SPS (11 items) and SIAS (10 items) show excellent discriminant and construct validity (Cronbach's α=.90 and .92), while specificity analysis showed that gender, marital status and educational level (SIAS(10): pSIAS, reducing the questionnaire burden for participants in epidemiological and biobehavioral research.

    Governments are preparing for a potential influenza pandemic. Therefore they need data to assess the possible impact of interventions. Face-masks worn by the general population could be an accessible and affordable intervention, if effective when worn under routine circumstances. We assessed transmission reduction potential provided by personal respirators, surgical masks and home-made masks when worn during a variety of activities by healthy volunteers and a simulated patient. All types of masks reduced aerosol exposure, relatively stable over time, unaffected by duration of wear or type of activity, but with a high degree of individual variation. Personal respirators were more efficient than surgical masks, which were more efficient than home-made masks. Regardless of mask type, children were less well protected. Outward protection (mask wearing by a mechanical head) was less effective than inward protection (mask wearing by healthy volunteers). Any type of general mask use is likely to decrease viral exposure and infection risk on a population level, in spite of imperfect fit and imperfect adherence, personal respirators providing most protection. Masks worn by patients may not offer as great a degree of protection against aerosol transmission.

    Our purpose was to assess stigma toward schizophrenia in a representative sample of the Brazilian general population. The sample consisted of 1015 individuals interviewed by telephone. A vignette describing someone with schizophrenia was read, and four stigma aspects regarding this hypothetical individual were assessed: stereotypes, restrictions, perceived prejudice and social distance. Latent profile analysis searched for stigma profiles among the sample. Multinomial logistic regression was used to find correlates of each class. Four stigma profiles were found; 'no stigma' individuals (n = 251) mostly displayed positive opinions. 'Labelers' (n = 222) scored high on social distance; they more often had familial contact with mental illness and more often labeled the vignette's disorder as schizophrenia. 'Discriminators', the group with the majority of individuals (n = 302), showed high levels of stigmatizing beliefs in all dimensions; discriminators were significantly older. 'Unobtrusive stigma' individuals (n = 240) seemed to demonstrate uncertainty or low commitment since they mostly answered items with the middle/impartial option. Some findings from the international literature were replicated; however, familial contact increased stigma, possibly denoting a locally modulated determinant. Hereby, our study also adds important cross-cultural data by showing that stigma toward schizophrenia is high in a Latin-American setting. We highlight the importance of analyzing the general population as a heterogeneous group, aiming to better elaborate anti-stigma campaigns. © The Author(s) 2013.

    This population based cross-sectional study was conducted on 8283 persons of all ages in five districts, selected conveniently, to assess the magnitude of ocular injuries, their causes and consequences in rural Bangladesh. Six Upazilas from five districts and from each Upazila one Union was selected randomly. One village, the ultimate cluster, was then selected conveniently from each Union. All people (n = 8283) in the 8 villages were then surveyed. Out of 8283 population (ranging from 1-120 years) surveyed, 167(2%) had history and/or evidence of past ocular trauma with a yearly incidence of 6.2 per 1000 per year. Study demonstrated a female predominance with male to female ratio being roughly 4:5. Majority (82%) had at least one episode of trauma in their life-time with mean age at 1st trauma being 20 years. Nearly 40% of the traumas were caused by blunt objects followed by penetrating object (22.3%) and sharp instrument (18.1%) with home being the primary place of occurrence (55.1%). Evidence of ocular trauma was found on eye-lid (15%), conjunctiva (11.4%) and cornea (10.2%) as scars. The older participants (≥ 30 years), females, illiterates, agriculture labors, housewives and household workers were more likely to receive trauma. Majority (86.8%) of the subjects received treatment following injury. The median time lapsed between injuries and receiving first treatment was 5 days and that between injury and visiting an eye-specialist was 18 days. Self-treatment and treatment from over-the-counter comprised 45% and 42.1% respectively followed by eye-specialists (25.5%), village quack (22.8%), graduate doctors (19.3%) and traditional healers (6.9%). About 87% received conservative management, with 12.4% needing hospitalization. Most of the injured (92.8%) and non-injured (95.2%) eyes had normal vision before trauma as informed by the respondents. Following trauma, 18% had impaired, 10.7% severely impaired vision and about 6% were blind. Job abstinence due to trauma

    Full Text Available Abstract Background In the context of AVAHAN, the India AIDS Initiative of the Bill & Melinda Gates Foundation, general population surveys (GPS were carried out between 2006 and 2008 in Belgaum (northern, Bellary (mid-state and Mysore (southern districts of Karnataka state, south India. Data from these three surveys were analysed to understand heterogeneity in HIV risk. Methods Outcome variables were the prevalence of HIV and sexually transmitted infections (STIs. Independent variables included age, district, place of residence, along with socio-demographic, medical and behavioural characteristics. Multivariate logistic regression was undertaken to identify characteristics associated with HIV and differences between districts, incorporating survey statistics to consider weights and cluster effects. Results The participation rate was 79.0% for the interview and 72.5% for providing a blood or urine sample that was tested for HIV. Belgaum had the highest overall HIV (1.43% and Herpes simplex type-2 (HSV-2 (16.93% prevalence, and the lowest prevalence of curable STIs. In Belgaum, the HIV epidemic is predominantly rural, and among women. In Bellary, the epidemic is predominantly in urban areas and among men, and HIV prevalence was 1.18%. Mysore had the lowest prevalence of HIV (0.80% and HSV-2 (10.89% and the highest prevalence of curable STIs. Higher HIV prevalence among men was associated with increasing age (p25-29years=11.22,95%CI:1.42-88.74, AOR30-34years=13.13,95%CI:1.67-103.19 and AOR35-39years=11.33,95%CI:1.32-96.83, having more than one lifetime sexual partner (AOR=4.61,95%CI:1.26-16.91 and having ever used a condom (AOR=3.32,95%CI:1.38-7.99. Having a dissolved marriage (being widowed/divorced/separated was the strongest predictor (AOR=10.98,95%CI: 5.35-22.57 of HIV among women. Being a muslim woman was associated with lower HIV prevalence (AOR=0.27,95%CI:0.08-0.87. Conclusion The HIV epidemic in Karnataka shows considerable heterogeneity

    Besides genetic factors there are environmental effects including nutritional habits which can influence the risk of age-related diseases. The aim of the study was to assess the age dependence of selected cardiovascular risk markers in two groups of subjects with different nutritional pattern. In 470 long-term vegetarians and 478 subjects of general population the following indicators were measured: total cholesterol, HDL-cholesterol, triacylglycerol, glucose, insulin concentrations, LDL-cholesterol, atherogenic index and insulin resistance IR(HOMA) were also calculated in studied subjects. Obtained data were evaluated according to age decades. Vegetarian vs. non-vegetarian concentrations of total cholesterol, LDL-cholesterol, insulin, and values of atherogenic index and IR(HOMA) were significantly reduced in all age decades. Vegetarian vs. non-vegetarian triacalglycerol concentrations were significantly reduced from 4th–7th decade. Vegetarian average decade values of all lipid parameters were in reference range. In non-vegetarian group, the risk average values of total cholesterol (>5.2 mmol/l) were found from 5th–7th decade, LDL-cholesterol (>3.3 mmol/l) in 7th decade and atherogenic index (>4) in 6th–7th decade. In vegetarians vs. non-vegetarians were noted the average decade values for total cholesterol ranging from 4.01–4.59 vs. 4.48–5.67 mmol/l, for triacylglycerols 1.00–1.33 vs. 1.13–1.74 mmol/l, for LDL-cholesterol 2.03–2.58 vs. 2.43–3.49 mmol/l, for atherogenic index 2.72–3.31 vs. 3.05–4.21 and for IR(HOMA) 0.99–1.15 vs. 1.15–1.84. Our data show significantly reduced mean age decade values of lipid and non-lipid cardiovascular risk markers in all adult vegetarians. Smaller changes of markers between decades compared to non-vegetarians document a protective effect of vegetarian nutrition in prevention of cardiovascular disease.

    Serum prostate-specific antigen (PSA) is an important tumour, marker which is widely used to trigger trans-rectal ultrasound (TRUS)-guided prostate biopsy. However, the PSA levels vary with race and ethnicity. Therefore, there is a need to have an Indian reference range. All adult male patients meeting the inclusion and exclusion criteria were enrolled in this study. They were subjected to assessment of serum total PSA, digital rectal examination and trans-abdominal ultrasound. If any one or more of these were found abnormal, then a TRUS-guided 12-core prostate biopsy was done. Patients who were detected to have prostatic cancer were excluded from the final analysis. The data so obtained was grouped among the following three age groups: 40-49, 50-59 and 60-70 years, and the age-specific PSA values, prostatic volume and PSA density were found. A total of 1772 patients were analysed. The mean serum total PSA was 1.76 ng/ml with a standard deviation of 2.566 ng/ml. Group-wise age distribution of the mean serum total PSA was 1.22, 1.97 and 2.08 ng/ml in 40-49, 50-59 and 60-70 years age groups. The mean total PSA and the age-specific PSA range tend to be lower in the Indians than the Western population.

    Seroepidemiological studies aim to understand population-level exposure and immunity to infectious diseases. Their results are normally presented as binary outcomes describing the presence or absence of pathogen-specific antibody, despite the fact that many assays measure continuous quantities. A population's natural distribution of antibody titers to an endemic infectious disease may include information on multiple serological states - naiveté, recent infection, non-recent infection, childhood infection - depending on the disease in question and the acquisition and waning patterns of immunity. In this study, we investigate 20,152 general-population serum samples from southern Vietnam collected between 2009 and 2013 from which we report antibody titers to the influenza virus HA1 protein using a continuous titer measurement from a protein microarray assay. We describe the distributions of antibody titers to subtypes 2009 H1N1 and H3N2. Using a model selection approach to fit mixture distributions, we show that 2009 H1N1 antibody titers fall into four titer subgroups and that H3N2 titers fall into three subgroups. For H1N1, our interpretation is that the two highest-titer subgroups correspond to recent and historical infection, which is consistent with 2009 pandemic attack rates. Similar interpretations are available for H3N2, but right-censoring of titers makes these interpretations difficult to validate.

    Levels of metalloids (As - urine) and heavy metals (Hg - urine, Cd - whole blood and Zn - serum) were determined by atomic absorption spectrometry in 601 subjects living in the area affected by the Aznalcollar mine spill (SW, Spain) and compared with those of a representative sample (960 subjects) selected from the Andalusian community (non-affected area), southern Spain. The characteristic parameters of the analytical method including uncertainty were determined for each metal. Potential associations of metal concentration with age, sex and body mass index as well as life-style habits (smoking, alcohol consumption and food habits) were explored. Concentrations of all the metals studied were statistically higher in the population of the affected area with respect to that of the non-affected area in Andalusia, although levels were always lower or similar to the values reported for the general population and below occupational reference limits. In conclusion, there is a lack of evidence that the spill had any incidence on human health in the population living in the affected area. There are few references in scientific literature reporting values from large series of samples, and hence our data could be useful for further studies

    Natural carcinogenic fibers are asbestos and asbestiform fibers present as a natural component of soils or rocks. These fibers are released into the environment resulting in exposure of the general population. Environmental contamination by fibers are those cases occurred in: rural regions of Turkey, in Mediterranean countries and in other sites of the world, including northern Europe, USA and China. Fluoro-edenite(FE) is a natural mineral species first isolated in Biancavilla, Sicily. The fibers are similar in size and morphology to some amphibolic asbestos fibers, whose inhalation can cause chronic inflammation and cancer. The aim of the current study is to assess the presence and features of pleural plaques (PPs) in Biancavilla's general population exposed to FE through a retrospective cross-sectional study. All High-Resolution Computed Tomography (HRCT) chest scans carried out between June 2009 and June 2015 in Biancavilla municipality hospital site (exposed subjects) were reviewed. The exposed groups were 1:1 subjects, matched according to age and sex distributions, with unexposed subjects (n.1.240) randomly selected among HRCT chest scans carried out in a Hospital 30 km away from Biancavilla. Subjects from Biancavilla with PPs were significantly more numerous than the control group ones (218 vs 38). Average age of either group was >60 years; the age of exposed subjects was significantly (p=0.0312) lesser than the unexposed group. In exposed subjects, in most PPs thickness ranged between 2 and 4.9 cm(38%, n=83); while in unexposed ones PPs thickness was less than 2 cm (55%, n=21). As to the size of PPs in exposed subjects, in most cases it ranged between 1 cm and 24% of chest wall (53%, n=116); while in unexposed ones the size of PPs was lesser than 1 cm (23%, n=58). Among exposed subjects, 36 cases (17%) PPs were detected with calcification, whereas in unexposed ones only three (8%) presented calcification. 137 lung parenchymal abnormalities were

    Background Several studies showed that blood pressure and lung function are associated. Additionally, a potential effect of antihypertensive medication, especially beta-blockers, on lung function has been discussed. However, side effects of beta-blockers have been investigated mainly in patients with already reduced lung function. Thus, aim of this analysis is to determine whether hypertension and antihypertensive medication have an adverse effect on lung function in a general adult population. Methods Within the population-based KORA F4 study 1319 adults aged 40-65 years performed lung function tests and blood pressure measurements. Additionally, information on anthropometric measurements, medical history and use of antihypertensive medication was available. Multivariable regression models were applied to study the association between blood pressure, antihypertensive medication and lung function. Results High blood pressure as well as antihypertensive medication were associated with lower forced expiratory volume in one second (p = 0.02 respectively p = 0.05; R2: 0.65) and forced vital capacity values (p = 0.01 respectively p = 0.05, R2: 0.73). Furthermore, a detailed analysis of antihypertensive medication pointed out that only the use of beta-blockers was associated with reduced lung function, whereas other antihypertensive medication had no effect on lung function. The adverse effect of beta-blockers was significant for forced vital capacity (p = 0.04; R2: 0.65), while the association with forced expiratory volume in one second showed a trend toward significance (p = 0.07; R2: 0.73). In the same model high blood pressure was associated with reduced forced vital capacity (p = 0.01) and forced expiratory volume in one second (p = 0.03) values, too. Conclusion Our analysis indicates that both high blood pressure and the use of beta-blockers, but not the use of other antihypertensive medication, are associated with reduced lung function in a general adult

    Full Text Available Irisin is a myokine, which is mainly inversely associated with the risk for non-communicable diseases. Irisin improves cellular energy metabolism by uncoupling the mitochondrial respiratory chain resulting in increased energy expenditure using lipids. To date potential associations between irisin concentration and lipid profile are poorly understood. Therefore, this investigation aimed to evaluate potential associations between irisin and lipid levels in the general population.Data of 430 men and 537 women from the population-based Study of Health in Pomerania (SHIP-TREND with available irisin and lipid concentrations were used. Analyses of variance, linear and logistic regression models adjusted for age, HBA1c, waist circumference, physical activity, smoking, alcohol consumption, systolic blood pressure, ALAT were calculated.We detected significantly inverse associations between irisin and circulating levels of total [beta coefficient 0.21 (standard error 0.08, p = 0.01], low-density cholesterol [-0.16 (0.07, p = 0.03] and triglycerides [-0.17 (0.08, p = 0.02] for men. Females without lipid lowering medication had an inverse association between irisin and total cholesterol [-0.12 (0.06, p = 0.05]. Further, male subjects with irisin concentrations in the third tertile had an increased odds for elevated low-density cholesterol [odds ratio 1.96 (95% confidence interval 1.07-3.48, p = 0.03 and triglyceride [1.95 (1.09-3.47, p = 0.02] levels, even after exclusion of subjects with lipid lowering medication. In addition, our data revealed an annual rhythm of serum irisin levels with peak levels arise in winter and summer months.This is the first investigation to report a significant association between circulating irisin and a favourable lipid profile in the general population. This may infer that higher irisin concentrations are associated with a reduced risk for non-communicable diseases.

    Full Text Available Objective: The aim of this study was to evaluate the type, severity and progression of psychiatric pathologies in a sample of 372 outpatients (age range 18–65 years referred by their primary general practitioners (GPs to an Urgent Referral Team (URT based in a psychiatric hospital in Aberdeen, Scotland. This team offers immediate appointments (1- to 7-day delays for rapid assessments and early interventions to the outpatients referred by their primary family doctors.Method: One-sample t-test and z statistic were used for data analysis. From the total population, a convenience sample of 40 people was selected and assessed to evaluate whether follow-up appointments after the first visit could reduce the severity of suicidal ideation, depression and anxiety in the outpatients seen by the URT. A two-sample t-test and a Wilcoxon signed-rank test were used to assess the variations in the scores during the follow-up visits.Results: We found a statistically significant prevalence of depressive disorders, comorbid with anxiety at first presentation in people who were females, white, never married, living with a partner, not studying and not in paid employment. The common presentation of borderline personality disorder and dysthymia in this population underscores its vulnerability to major socioeconomic challenges.Conclusion: The data confirmed the impact that primary care cooperation with psychiatric hospitals can have on the psychiatric system, and as a reflection, on the population’s mental health and well-being. In fact, active cooperation and early diagnosis and intervention will help detect cases at risk in the general population and reduce admissions into hospitals.

    Full Text Available Abstract Background This study focused on respiratory symptoms due to occupational exposures in a contemporary general population cohort. Subjects were from the Dutch Monitoring Project on Risk Factors for Chronic Diseases (MORGEN. The composition of this population enabled estimation of respiratory risks due to occupation from the recent past for both men and women. Methods The study subjects (aged 20–59 were all inhabitants of Doetinchem, a small industrial town, and came from a survey of a random sample of 1104 persons conducted in 1993. A total of 274 cases with respiratory symptoms (subdivided in asthma and bronchitis symptoms and 274 controls without symptoms were matched for age and sex. Relations between industry and occupation and respiratory symptoms were explored and adjusted for smoking habits and social economic status. Results Employment in the 'construction' (OR = 3.38; 95%CI 1.02 – 11.27, 'metal' (OR = 3.17; 95%CI 0. 98 – 10.28, 'rubber, plastics and synthetics' (OR = 6.52; 95%CI 1.26 – 53.80, and 'printing' industry (OR = 3.96; 95%CI 0.85 – 18.48 were positively associated with chronic bronchitis symptoms. In addition, the 'metal' industry was found to be weakly associated with asthma symptoms (OR = 2.59; 95%CI 0.87 – 7.69. Duration of employment within these industries was also positively associated with respiratory symptoms. Conclusion Respiratory symptoms in the general population are traceable to employment in particular industries even in a contemporary cohort with relatively young individuals.

    The influence of social support on health and quality of life has been well documented. There is less evidence on whether health status affects social support, and little is known about longitudinal relationships between social support and health in early adulthood. This study investigates these associations using both concurrent and time-lagged measures at 5 time-points over 12 years during early adulthood. A population-based cohort of 9,758 young women from the Australian Longitudinal Study on Women's Health was used. Women were aged 22-27 in 2000 and 35-39 in 2012. The General Health subscale of the SF-36 and the MOS Social Support Survey 6-item Scale were used, with scores standardised to a range of 0-100. Longitudinal tobit models were used, because both social support and general health data were left skewed, with marked ceiling effects. All models were adjusted for status of the outcome of interest at the immediately previous survey. With both concurrent and time-lagged measures, there was a statistically significant difference in mean general health scores across social support quintiles after adjusting for demographic and behavioural covariates: lower general health was associated with lower social support. In reverse, social support mean scores were also significantly different across general health quintiles in both concurrent and time-lagged fully adjusted models. Social support is significantly associated with both current and subsequent general health in early adulthood. The significance of the reverse associations indicates that the two mutually influence each other. This study highlights the importance of social support as a health-related quality of life issue.

    Full Text Available The nares represent an important bacterial reservoir for endogenous infections. This study aimed to assess the prevalence of nasal colonization by different important pathogens, the associated antimicrobial susceptibility and risk factors. We performed a prospective cohort study among 1878 nonhospitalized volunteers recruited from the general population in Germany. Participants provided nasal swabs at three time points (each separated by 4–6 months. Staphylococcus aureus, Enterobacteriaceae and important nonfermenters were cultured and subjected to susceptibility testing. Factors potentially influencing bacterial colonization patterns were assessed. The overall prevalence of S. aureus, Enterobacteriaceae and nonfermenters was 41.0, 33.4 and 3.7%, respectively. Thirteen participants (0.7% were colonized with methicillin-resistant S. aureus. Enterobacteriaceae were mostly (>99% susceptible against ciprofloxacin and carbapenems (100%. Extended-spectrum β-lactamase–producing isolates were not detected among Klebsiella oxytoca, Klebsiella pneumoniae and Escherichia coli. Several lifestyle- and health-r
