Irritable bowel syndrome (IBS) is a complication that can follow gastrointestinal infection, but it is not clear if patients also develop chronic fatigue. We investigated the prevalence and odds ratio of IBS and chronic fatigue 10 years after an outbreak of Giardia lamblia, compared with a control cohort, and changes in prevalence over time. We performed a prospective follow-up study of 1252 laboratory-confirmed cases of giardiasis (exposed), which developed in Bergen, Norway in 2004. Statistics Norway provided us with information from 2504 unexposed individuals from Bergen, matched by age and sex (controls). Questionnaires were mailed to participants 3, 6, and 10 years after the outbreak. Results from the 3- and 6-year follow-up analyses have been published previously. We report the 10-year data and changes in prevalence among time points, determined by logistic regression using generalized estimating equations. The prevalence of IBS 10 years after the outbreak was 43% (n = 248) among 576 exposed individuals and 14% (n = 94) among 685 controls (adjusted odds ratio for development of IBS in exposed individuals, 4.74; 95% CI, 3.61-6.23). At this time point, the prevalence of chronic fatigue was 26% (n = 153) among 587 exposed individuals and 11% (n = 73) among 692 controls (adjusted odds ratio, 3.01; 95% CI, 2.22-4.08). The prevalence of IBS among exposed persons did not change significantly from 6 years after infection (40%) to 10 years after infection (43%; adjusted odds ratio for the change 1.03; 95% CI, 0.87-1.22). However, the prevalence of chronic fatigue decreased from 31% at 6 years after infection to 26% at 10 years after infection (adjusted odds ratio for the change 0.74; 95% CI, 0.61-0.90). The prevalence of IBS did not change significantly from 6 years after an outbreak of Giardia lamblia infection in Norway to 10 years after. However, the prevalence of chronic fatigue decreased significantly from 6 to 10 years afterward. IBS and chronic fatigue were

Genome-wide association studies (GWAS) have identified thousands of loci that are robustly associated with complex diseases. The use of linear mixed model (LMM) methodology for GWAS is becoming more prevalent due to its ability to control for population structure and cryptic relatedness and to increase power. The odds ratio (OR) is a common measure of the association of a disease with an exposure ( e.g. , a genetic variant) and is readably available from logistic regression. However, when the LMM is applied to all-or-none traits it provides estimates of genetic effects on the observed 0-1 scale, a different scale to that in logistic regression. This limits the comparability of results across studies, for example in a meta-analysis, and makes the interpretation of the magnitude of an effect from an LMM GWAS difficult. In this study, we derived transformations from the genetic effects estimated under the LMM to the OR that only rely on summary statistics. To test the proposed transformations, we used real genotypes from two large, publicly available data sets to simulate all-or-none phenotypes for a set of scenarios that differ in underlying model, disease prevalence, and heritability. Furthermore, we applied these transformations to GWAS summary statistics for type 2 diabetes generated from 108,042 individuals in the UK Biobank. In both simulation and real-data application, we observed very high concordance between the transformed OR from the LMM and either the simulated truth or estimates from logistic regression. The transformations derived and validated in this study improve the comparability of results from prospective and already performed LMM GWAS on complex diseases by providing a reliable transformation to a common comparative scale for the genetic effects.

Full Text Available CONTEXT AND OBJECTIVE: Empirical discussion regarding an association between koilocytosis and vulvovaginitis often occurs. Thus, the objective of this study was to assess the prevalence of microorganisms associated with bacterial vaginosis and vulvovaginitis in women with and without koilocytosis. DESIGN AND SETTING: Analytical cross-sectional study including two cohorts of women (with and without koilocytosis who attended a cancer hospital in the city of Goiânia, state of Goiás. METHODS: A total of 102 patients entered the study. The whiff test, Gram and Papanicolaou staining and bacterial and fungal culturing were performed. The results were observed using univariate analysis. The odds ratio and confidence interval (CI of the variables were calculated; P-values < 0.05 were considered significant. RESULTS: The prevalence of bacterial colonization was similar in patients with and without koilocytosis. The odds ratio for candidiasis was 1.43 (CI 1.05-1.95 and the odds ratio for trichomoniasis was 1.78 (CI 1.49-2.12, in patients with koilocytosis. CONCLUSIONS: The prevalence of candidiasis and trichomoniasis seems to be higher in patients with koilocytosis.

We aimed to examine the prevalence of several types of childhood adversity across adult cohorts, whether age moderates the effect of childhood adversity on mental health, the relationship between childhood adversity and psychopathology among older adults, the dose-response relationship between number of types of childhood adversities and mental disorders in later life, and whether lifetime mental health treatment reduces the odds of psychopathology among older survivors of childhood adversity. In a population-based, cross-sectional study on a nationally representative U.S. sample, we studied 34,653 community-dwelling Americans 20 years and older, including 7,080 adults 65 years and older from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions. Trained lay interviewers assessed past-year mood and anxiety disorders and lifetime personality disorders. Participants self-reported childhood adversity based on questions from the Adverse Childhood Experiences Study. Childhood adversity was prevalent across five age cohorts. In our adjusted models, age did not moderate the effect of childhood adversity on mental disorders. Older adults who experienced childhood adversity had higher odds of having mood (odds ratio: 1.73; 95% confidence interval: 1.32-2.28), anxiety (odds ratio: 1.48; 95% confidence interval: 1.20-1.83), and personality disorders (odds ratio: 2.11; 95% confidence interval: 1.75-2.54) after adjusting for covariates. An increasing number of types of childhood adversities was associated with higher odds of personality disorders and somewhat higher odds of anxiety disorders. Treatment-seeking was associated with a reduced likelihood of anxiety and, especially, mood disorders in older adult childhood adversity survivors. These results emphasize the importance of preventing childhood adversity and intervening once it occurs to avoid the negative mental health effects that can last into old age.

To study the prevalence of poorly controlled vitamin K antagonist anticoagulation in Spain in patients with nonvalvular atrial fibrillation, and to identify associated factors. We studied 1056 consecutive patients seen at 120 cardiology clinics in Spain between November 2013 and March 2014. We analyzed the international normalized ratio from the 6 months prior to the patient's visit, calculating the prevalence of poorly controlled anticoagulation, defined as < 65% time in therapeutic range using the Rosendaal method. Mean age was 73.6 years (standard deviation, 9.8 years); women accounted for 42% of patients. The prevalence of poorly controlled anticoagulation was 47.3%. Mean time in therapeutic range was 63.8% (25.9%). The following factors were independently associated with poorly controlled anticoagulation: kidney disease (odds ratio = 1.53; 95% confidence interval, 1.08-2.18; P = .018), routine nonsteroidal anti-inflammatory drugs (odds ratio = 1.79; 95% confidence interval, 1.20-2.79; P = .004), antiplatelet therapy (odds ratio = 2.16; 95% confidence interval, 1.49-3.12; P < .0001) and absence of angiotensin receptor blockers (odds ratio = 1.39; 95% confidence interval, 1.08-1.79; P = .011). There is a high prevalence of poorly controlled vitamin K antagonist anticoagulation in Spain. Factors associated with poor control are kidney disease, routine nonsteroidal anti-inflammatory drugs, antiplatelet use, and absence of angiotensin receptor blockers.

Vitamin D status has been hypothesized to protect against development of diabetic retinopathy via its anti-inflammatory and anti-angiogenic properties. Additionally, in vitro and in vivo studies suggest vitamin D favorably influences blood pressure and blood glucose control, strong risk factors for diabetic retinopathy. We examined the association between vitamin D status and prevalent diabetic retinopathy in participants with diabetes from a population-based cohort. Among participants in the Atherosclerosis Risk in Communities (ARIC) study with diabetes at visit 3 (1993-1995), 1339 (906 Caucasians, 433 African Americans) had serum 25-hydroxyvitamin (25[OH]D) concentrations assessed at visit 2 (1989-1992) and nonmydriatic retinal photographs taken at visit 3. Dietary intake of vitamin D was assessed at visit 1 (1987-1989). Logistic regression was used to estimate odds ratios (ORs) and 95 % confidence intervals (CIs) for diabetic retinopathy by categories of season-adjusted 25(OH)D (diabetes. We further adjusted for HBA1c and hypertension to examine if 25(OH)D influenced diabetic retinopathy via its effects on either glycemic control or blood pressure. ORs (95 % CIs) for retinopathy, adjusted for race and duration, were 0.77 (0.45-1.32), 0.64 (0.37-1.10), and 0.39 (0.20-0.75), p for trend = 0.001, for participants with 25(OH)D of 30-retinopathy. 25(OH)D concentrations ≥75 nmol/L were associated with lower odds of any retinopathy assessed 3 years later. We speculate this may be due in part to vitamin D's influence on blood glucose control.

concern when using peripheral densitometry is the poor correlation with the central measurements. The main aim of this study is, therefore, to assess the possibility of expressing ultrasound measurements at the heel and bone mineral density (BMD) measured at the distal forearm as fracture odds ratios...... rather than an absolute measure of bone mass. METHODS: A total of 76 women with lower forearm fracture, 47 women with hip fracture and 231 age-matched women (controls) were included. All had broadband ultrasound attenuation (BUA) and speed of sound (SOS) measured at the heel using the DTU-one ultrasound.......8; 5.2) for heel-BUA (T-score cutoff: -2.3), 4.1 (2.3; 7.4) for heel-SOS (-2.1) and 2.2 (1.3; 3.7) for lower forearm BMD (-2.7). The odds ratio for hip fracture was 3.4 (1.5-7.7) for heel-BUA (-2.7), 3.6 (1.6; 8.1) for heel-SOS (-2.6) and 3.2 (1.4; 7.4) for lower forearm BMD (-2.9). CONCLUSION...

The objectives of this study were to investigate the prevalence of dystocia in camel herds, its forms in primi- and multipara, the risks to fetus and dam, and the associated hematobiochemical changes. A total of 1890 calvings were surveyed for the prevalence of dystocia. Cases with dystocia (n=107) were examined for causes and treated with traction, fetotomy or Cesarean section. Logistic regression was performed to identify risk factors. The dependent variables were the fetal and maternal mortality, while the independent variables were parity, duration of dystocia, causes of dystocia, and method of treatment. Blood samples were collected from all dystocia camels and six controls for hematology and concentrations of serum amyloid A (SAA), haptoglobin (Hp), estradiol-17β (E2), progesterone (P4), total protein, albumin, calcium, phosphorus, magnesium, blood urea nitrogen (BUN), creatinine and aspartate aminotransferase (AST). The overall prevalence of dystocia was 8.6%. Risk of dystocia was higher in camels managed in an intensive system than in those in a free system (Odds ratio=1.9, P=0.0003) and higher in primipara than in multipara (Odds ratio 1.7, P=0.005). Abnormal posture was the most important cause of dystocia (51.4%). Uterine torsion was the second most important cause (23.4%) and was mainly observed in multipara (P=0.0006). Dystocia was linked to high fetal mortality (87.9%). A significant relationship was found between fetal death and duration of dystocia (Odds ratio=8.04, P=0.005). The percentage of dam mortality was 17.8%. Significant associations were detected between dam mortality rate and the duration of dystocia (Odds ratio=4.74, P=0.03) and fetal viability (Odds ratio=5.82, P=0.02). Increasing duration of dystocia was associated with significant increases in SAA, Hp, BUN and AST, but with decreases in E2 (Pdystocia in dromedary camels, and fetal and maternal deaths were mainly associated with the duration of dystocia.

The purpose of this study was to investigate the prevalence of hypothyroidism among hospitalized patients with type 2 diabetes mellitus and its related factors, and to assess the prevalence of macrovascular and microvascular diseases among type 2 diabetes mellitus inpatients with hypothyroidism and euthyroidism. A total of 1662 type 2 diabetes mellitus inpatients hospitalized at the Metabolic Diseases Hospital, Tianjin Medical University from 1 January 2008 to 1 March 2013 were included in this study. Information on demographic and anthropometric factors and additional variables related to hypothyroidism were collected from medical records. Prevalence rates were calculated and standardized using direct method based on the age-specific and sex-specific structure of all participants. Data were analyzed using binary logistic regression with adjustment for potential confounders. The prevalence of hypothyroidism among type 2 diabetes mellitus inpatients was 6.8 %, and 77.0 % of the patients with hypothyroidism had subclinical hypothyroidism. The prevalence of hypothyroidism increased with age, and was higher in women (10.8 %) than in men (3.4 %). Older age (odds ratio, 1.74; 95 % confidence interval, 1. 05 to 2.89), female gender (odds ratio, 2.02; 95 % confidence interval, 1.05 to 3.87), and positive thyroid peroxidase antibody (odds ratio, 4.99; 95 % confidence interval, 2.83 to 8.79) were associated with higher odds of hypothyroidism among type 2 diabetes mellitus inpatients. The type 2 diabetes mellitus inpatients with hypothyroidism had higher prevalence of cerebrovascular diseases than those with euthyroidism after adjustment for age and gender. The prevalence of hypothyroidism among type 2 diabetes mellitus inpatients was 6.8 %, and most patients had subclinical hypothyroidism. Older age, female gender, and positive thyroid peroxidase antibody could be indicators for detecting hypothyroidism in type 2 diabetes mellitus inpatients.

Beta-binomial model for meta-analysis of odds ratios.

Science.gov (United States)

Bakbergenuly, Ilyas; Kulinskaya, Elena

2017-05-20

In meta-analysis of odds ratios (ORs), heterogeneity between the studies is usually modelled via the additive random effects model (REM). An alternative, multiplicative REM for ORs uses overdispersion. The multiplicative factor in this overdispersion model (ODM) can be interpreted as an intra-class correlation (ICC) parameter. This model naturally arises when the probabilities of an event in one or both arms of a comparative study are themselves beta-distributed, resulting in beta-binomial distributions. We propose two new estimators of the ICC for meta-analysis in this setting. One is based on the inverted Breslow-Day test, and the other on the improved gamma approximation by Kulinskaya and Dollinger (2015, p. 26) to the distribution of Cochran's Q. The performance of these and several other estimators of ICC on bias and coverage is studied by simulation. Additionally, the Mantel-Haenszel approach to estimation of ORs is extended to the beta-binomial model, and we study performance of various ICC estimators when used in the Mantel-Haenszel or the inverse-variance method to combine ORs in meta-analysis. The results of the simulations show that the improved gamma-based estimator of ICC is superior for small sample sizes, and the Breslow-Day-based estimator is the best for n⩾100. The Mantel-Haenszel-based estimator of OR is very biased and is not recommended. The inverse-variance approach is also somewhat biased for ORs≠1, but this bias is not very large in practical settings. Developed methods and R programs, provided in the Web Appendix, make the beta-binomial model a feasible alternative to the standard REM for meta-analysis of ORs. © 2017 The Authors.

This study aimed to clarify relationships between prevalence of risk behaviors and sleep duration among Japanese high school students. Data from a national survey, the Japan Youth Risk Behavior Survey 2011 (the subjects were 9,778 students: 5,027 males, 4,751 females, in the first grade to the third grade of 102 schools randomly selected among high schools throughout Japan) was used for this analysis. We focused on nine items of risk behavior in JYRBS: "lack of vigorous physical activity," "skipping breakfast," "current cigarette use," "current alcohol use," "lifetime thinner use," "ever had sexual intercourse," "rarely or never wore seatbelts," "in a physical fight," and "seriously considered attempting suicide." Students with less than six hours of sleep duration accounted for approximately 40% of males and females. The odds ratios of prevalence of each of the nine risk behaviors were calculated on the basis of the group "six hours or more and less than eight hours" of sleep, whose prevalence of risk behaviors was the lowest. In the group with "four hours or more and less than six hours," the odds ratios of "lack of vigorous physical activity" and "skipping breakfast" for both males and females were significantly high. Furthermore, in the group with shorter sleep duration of "less than four hours," the odds ratios of all nine risk behaviors for males (odds ratios: 1.47-3.28) and eight risk behaviors (except for "rarely or never wore seatbelts") for females (1.54-4.68) were significantly high. On the other hand, in the group with long sleep duration of "10 hours or more," the odds ratios of "current cigarette use" and "lifetime thinner use" for both males and females were significantly high. It was shown that short sleep duration of less than six hours and long sleep duration of 10 hours or more related to the prevalence of youth risk behaviors among Japanese high school students. It was suggested that sleep duration should be considered as an important category

Selenium (Se) has been reported to protect against the neurotoxicity of mercury (Hg). However, the effect of Se against Hg on cardiovascular diseases remains unclear. Inuit living in the Arctic have high exposure to both Se and Hg through their marine mammal and fish rich traditional diet. To characterize the co-exposure of Hg and Se among Inuit in Canada and to assess the associations between Hg, Se and cardiovascular health outcomes, including stroke, hypertension, and myocardial infarction (MI). Data was collected from the International Polar Year Inuit Health Survey (IHS) conducted in 2007 and 2008. Blood Se and Hg were measured, and self-report cardiovascular health outcomes were collected through a questionnaire interview from 2169 adults aged 18 and above. The mean age was 42.4years, and 38.7% of the participants were male. The geometric means (GM) of blood Se and total Hg were 319.5μg/L and 7.0μg/L, respectively. The crude prevalence of heart attack, stroke and hypertension were 3.55%, 2.36%, and 24.47% respectively. Participants were categorized into 4 exposure groups according to blood Hg (high: ≥7.8μg/L; low: <7.8μg/L), and Se (high: ≥280μg/L; low: <280μg/L). The odds ratio (OR) of cardiovascular outcomes were estimated using general linearized models. Results showed the low Se and high Hg group had a higher prevalence of cardiovascular disease (OR=1.76 for hypertension, 1.57 for stroke, and 1.26 for MI. However, the prevalence was decreased in both the high Se and low Hg group (OR=0.57 for hypertension, 0.44 for stroke, and 0.27 for MI) and the high Se and high Hg group (OR=1.14 for hypertension, 0.31 for stroke, and 0.80 for MI). The high Se and low Hg group had the lowest prevalence of cardiovascular outcomes, except for stroke. These results provide evidence that Se may exhibit a protective effect against Hg on cardiovascular disease. Copyright © 2017 Elsevier Ltd. All rights reserved.

The association between opium use and bladder cancer has been investigated in many studies, with varying reporting results reported. This study aims to estimate the total odds ratio for the association between bladder cancer and opium consumption using meta-analysis. The study was designed according to PRISMA guidelines. Two independent researchers searched for the relevant studies using PubMed, Web of Science, Scopus, OVID, Embase, and Google Scholar. After systematic screening of the studies identified during the first step, Cochrane risk of bias tool was determined for the selected studies. The case-control and the cohort studies were investigated to assess risk of bladder cancer due to opium use. In addition, the cross-sectional studies were analysed separately to assess frequency of opium consumption. These estimates were combined using the inverse variance method. Fixed or random effect models were applied to combine the point odds ratios. The heterogeneity between the primary results was assessed using the Cochran test and I-square index. The suspected factors for heterogeneity were investigated using meta-regression models. An Egger test was conducted to identify any probable publication bias. Forest plots illustrated the point and pooled estimates. All analyses were performed using Stata version 14 software and RevMan version 5.3. We included 17 primary studies (11 case-control, one cohort and five cross-sectional) in the final meta-analysis. The total odds ratios (95% confidence intervals) for developing bladder cancer by opium use alone, and concurrent use of opium and cigarettes were estimated as 3.85 (3.05-4.87) and 5.7 (1.9-16.3) respectively. The odds ratio (95% confidence interval) for opium use with or without cigarette smoking was estimated as 5.3 (3.6-7.7). This meta-analysis showed that opium use similar to cigarette smoking and maybe with similar mechanisms can be a risk factor for bladder cancer. It is therefore expected to be a risk factor

Hypothyroidism and frozen shoulder (FS) have been associated, although this relationship remains uncertain. The main objective of this study was to determine the prevalence of hypothyroidism in patients with FS. A case-control study was performed to compare FS patients (cases) with patients who visited an orthopedic service for other clinical conditions (controls). FS was diagnosed according to specific criteria based on anamnesis, physical examination, and shoulder radiographs. A specific questionnaire was applied, and measurements of serum thyroid-stimulating hormone (TSH) and free tetraiodothyronine were performed in all subjects. We evaluated 401 shoulders from 93 FS patients and 151 controls. The prevalence of hypothyroidism diagnosis was significantly higher in the FS group (27.2% vs. 10.7%; P = .001). There was also a tendency for higher prevalence of bilateral FS among patients with elevated TSH levels (P = .09). Mean serum TSH levels were higher in patients with bilateral FS compared with those with unilateral compromise (3.39 vs. 2.28; P = .05) and were higher in patients with severe FS compared with those with mild and moderate FS together (3.15 vs. 2.21; P = .03). Multivariate analysis showed that FS was independently related to a diagnosis of hypothyroidism (odds ratio, 3.1 [1.5-6.4]; P = .002). There was a trend toward independent association between high serum TSH levels and both severe (odds ratio, 3.5 [0.8-14.9]; P = .09) and bilateral (odds ratio, 11.7 [0.9-144.8]; P = .05) compromise. The prevalence of hypothyroidism was significantly higher in FS patients than in controls. The results suggest that higher serum TSH levels are associated with bilateral and severe cases of FS.

The rotational vibrational (RV) model of odd nuclei is generalized to odd-odd nuclei. The hamiltonian, wave functions and matrix elements of the RV-model of odd-odd nuclei are obtained. The expressions obtained for matrix elements of the RV-model of odd-odd nuclei can be used to study the role of vibrational additions in low-lying two-particle states of odd-odd deformed nuclei. Such calculations permit to study more correctly the residual neutron-proton interaction of valent nucleons with respect to collectivization effects

Autosomal dominant polycystic kidney disease is the most common inheritable kidney disease, frequently thought to become symptomatic in adulthood. However, patients with autosomal dominant polycystic kidney disease may develop signs or symptoms during childhood, in particular hypertension. Although ambulatory BP monitoring is the preferred method to diagnose hypertension in pediatrics, data in children with autosomal dominant polycystic kidney disease are limited. Our retrospective multicenter study was conducted to collect ambulatory BP monitoring recordings from patients with autosomal dominant polycystic kidney disease age 1 cm per kidney and daytime hypertension (odds ratio, 1.70; 95% confidence interval, 1.21 to 2.4; P =0.002), nighttime hypertension (odds ratio, 1.31; 95% confidence interval, 1.05 to 1.63; P =0.02), or 24-hour hypertension (odds ratio, 1.39; 95% confidence interval, 1.08 to 1.81; P =0.01). Kidney length, expressed as SD score, was also significantly associated with nighttime hypertension (odds ratio, 1.23; 95% confidence interval, 1.06 to 1.42; P =0.10). These data indicate high prevalence of hypertension in children with autosomal dominant polycystic kidney disease starting at young ages. Copyright © 2018 by the American Society of Nephrology.

To examine the rural-urban differences in the prevalence of diabetes and coronary heart disease, and the extent to which they are explained by the presence of established risk factors including poverty. Cross-sectional study of more than 214,000 respondents using data from the US Centers for Disease Control and Prevention's (CDC's) 2008 Behavioral Risk Factor Surveillance System. Logistic regression models were utilized; prevalence odds ratios with corresponding confidence intervals and P-values are provided. The crude prevalence rates of diabetes and coronary heart disease were 8.6% (P = 0.001) and 38.8% (P rural areas compared with urban areas, respectively. The higher prevalence in rural areas of many of the common risk factors for these conditions, including poverty (P rural areas [prevalence odds ratio (POR) = 0.94, P = 0.032], but the prevalence of coronary heart disease was higher (POR = 1.09, P = 0.011). The higher prevalence of diabetes and coronary heart disease in rural populations in the USA presents a formidable public health challenge. It exacerbates many of the pre-existing rural health disparities, including a lack of access to financial resources and primary care providers. Copyright © 2012 The Royal Society for Public Health.

Increased prevalence of metabolic syndrome in patients with acne inversa.

Directory of Open Access Journals (Sweden)

Robert Sabat

Full Text Available BACKGROUND: Acne inversa (AI; also designated as Hidradenitis suppurativa is a common chronic inflammatory skin disease, localized in the axillary, inguinal and perianal skin areas that causes painful, fistulating sinuses with malodorous purulence and scars. Several chronic inflammatory diseases are associated with the metabolic syndrome and its consequences including arteriosclerosis, coronary heart disease, myocardial infraction, and stroke. So far, the association of AI with systemic metabolic alterations is largely unexplored. METHODS AND FINDINGS: A hospital-based case-control study in 80 AI patients and 100 age- and sex-matched control participants was carried out. The prevalence of central obesity (odds ratio 5.88, hypertriglyceridemia (odds ratio 2.24, hypo-HDL-cholesterolemia (odds ratio 4.56, and hyperglycemia (odds ratio 4.09 in AI patients was significantly higher than in controls. Furthermore, the metabolic syndrome, previously defined as the presence of at least three of the five alterations listed above, was more common in those patients compared to controls (40.0% versus 13.0%; odds ratio 4.46, 95% confidence interval 2.02 to 9.96; P<0.001. AI patients with metabolic syndrome also had more pronounced metabolic alterations than controls with metabolic syndrome. Interestingly, there was no correlation between the severity or duration of the disease and the levels of respective parameters or the number of criteria defining the metabolic syndrome. Rather, the metabolic syndrome was observed in a disproportionately high percentage of young AI patients. CONCLUSIONS: This study shows for the first time that AI patients have a high prevalence of the metabolic syndrome and all of its criteria. It further suggests that the inflammation present in AI patients does not have a major impact on the development of metabolic alterations. Instead, evidence is given for a role of metabolic alterations in the development of AI. We recommend

We determined the overall prevalence of typical orofacial clefts and the potential risks for nonsyndromic cleft lip with or without cleft palate in a university hospital from West México. For the prevalence, 227 liveborn infants with typical orofacial clefts were included from a total of 81,193 births occurred during the period 2009-2016 at the "Dr. Juan I. Menchaca" Civil Hospital of Guadalajara (Guadalajara, Jalisco, Mexico). To evaluate potential risks, a case-control study was conducted among 420 newborns, including only those 105 patients with nonsyndromic cleft lip with or without cleft palate (cases), and 315 infants without birth defects (controls). Data were analyzed using multivariable logistic regression analysis expressed as adjusted odds ratio with 95% confidence intervals . The overall prevalence for typical orofacial clefts was 28 per 10,000 (95% confidence interval: 24.3-31.6), or 1 per 358 live births. The mean values for the prepregnancy weight, antepartum weight, and pre-pregnancy body mass index were statistically higher among the mothers of cases. Infants with nonsyndromic cleft lip with or without cleft palate had a significantly higher risk for previous history of any type of congenital anomaly (adjusted odds ratio: 2.7; 95% confidence interval: 1.4-5.1), history of a relative with cleft lip with or without cleft palate (adjusted odds ratio: 19.6; 95% confidence interval: 8.2-47.1), and first-trimester exposures to progestogens (adjusted odds ratio: 6.8; 95% CI 1.8-25.3), hyperthermia (adjusted odds ratio: 3.4; 95% confidence interval: 1.1-10.6), and common cold (adjusted odds ratio: 3.6; 95% confidence interval: 1.1-11.9). These risks could have contributed to explain the high prevalence of orofacial clefts in our region of Mexico, emphasizing that except for history of relatives with cleft lip with or without cleft palate, most are susceptible of modification. © 2018 Japanese Teratology Society.

Dynamical symmetries for odd-odd nuclei

International Nuclear Information System (INIS)

Balantekin, A.B.

1986-01-01

Recent work for developing dynamical symmetries and supersymmetries is reviewed. An accurate description of odd-odd nuclei requires inclusion of the fermion-fermion force (the residual interaction) and the distinguishing of fermion configurations which are particle like and those which are hole like. A parabolic dependence of the proton-neutron multiplet in odd-odd nuclei is demonstrated. It is shown that a group structure for Bose-Fermi symmetries can be embedded in a supergroup. These methods are used to predict level schemes for Au-196 and Au-198. 11 refs., 3 figs

2008-10-01

Fatigue, which is a common complaint among medical students, is related to poor academic outcomes. Because impaired dietary habits, such as skipping breakfast and taking meals irregularly, are correlated with poor school performances, whether those dietary habits were associated with the prevalence of fatigue was determined in medical students. The study group consisted of 127 healthy second-year medical students attending Osaka City University Graduate School of Medicine. They completed a questionnaire dealing with fatigue (Japanese version of the Chalder Fatigue Scale), lifestyle, and academic performance. On multivariate logistic regression analyses adjusted for age, gender, body mass index, and nocturnal sleeping hours, skipping breakfast (completely skipping breakfast everyday versus having breakfast everyday; odds ratio 7.81, 95% confidence interval 2.00-30.52, P = 0.003) and taking meals irregularly (completely irregular versus always regular; odds ratio 6.89, 95% confidence interval 1.20-39.55, P = 0.030) were positively correlated with the prevalence of fatigue. Skipping breakfast and taking meals irregularly are associated with the prevalence of fatigue in medical students.

BACKGROUND Over the past 10 years, there has been a significant increase in the use of assisted reproductive technologies in Canada, however, little is known about the overall prevalence of infertility in the population. The purpose of the present study was to estimate the prevalence of current infertility in Canada according to three definitions of the risk of conception. METHODS Data from the infertility component of the 2009–2010 Canadian Community Health Survey were analyzed for married and common-law couples with a female partner aged 18–44. The three definitions of the risk of conception were derived sequentially starting with birth control use in the previous 12 months, adding reported sexual intercourse in the previous 12 months, then pregnancy intent. Prevalence and odds ratios of current infertility were estimated by selected characteristics. RESULTS Estimates of the prevalence of current infertility ranged from 11.5% (95% CI 10.2, 12.9) to 15.7% (95% CI 14.2, 17.4). Each estimate represented an increase in current infertility prevalence in Canada when compared with previous national estimates. Couples with lower parity (0 or 1 child) had significantly higher odds of experiencing current infertility when the female partner was aged 35–44 years versus 18–34 years. Lower odds of experiencing current infertility were observed for multiparous couples regardless of age group of the female partner, when compared with nulliparous couples. CONCLUSIONS The present study suggests that the prevalence of current infertility has increased since the last time it was measured in Canada, and is associated with the age of the female partner and parity.

To determine the prevalence of corporal punishment in Washington State and the factors associated with its use in Washington elementary and secondary schools. Cross-sectional mail survey performed during the summer of 1992. All elementary and secondary schools in the state of Washington. One thousand eighteen schools (47%) responded to the survey, of which 80% were publicly funded and 63% were located in urban areas. The study sample closely resembled the profile of all schools in the state. Almost 11% of participating schools permitted corporal punishment at the time of the survey and 3.2% reported its actual use during the 1991-1992 school year, resulting in an estimated prevalence of 7.2 incidents per 1000 students per year. Sixteen percent of corporal punishment actions occurred in schools not permitting its use. Ninety percent of public schools relied on district policy regarding corporal punishment. School characteristics associated with the use of corporal punishment included rural location (crude odds ratio, 2.2; 95% confidence interval, 1.5 to 3.4), enrollment of less than 500 students (crude odds ratio, 1.7; 95% confidence interval, 1.1 to 2.7), and kindergarten to eighth-grade or kindergarten to 12th-grade enrollment (crude odds ratio, 2.5; 95% confidence interval, 1.6 to 3.9). The lack of a statewide ban on school corporal punishment at the time of this survey was associated with the continued use of corporal punishment against children in districts that continued to permit it. School policies against corporal punishment were associated with much lower prevalence. Continued efforts are needed to enact and enforce laws in the remaining states that have not yet banned corporal punishment.

Random interactions, isospin, and the ground states of odd-A and odd-odd nuclei

Horoi, Mihai; Volya, Alexander; Zelevinsky, Vladimir

2002-01-01

It was recently shown that the ground state quantum numbers of even-even nuclei have a high probability to be reproduced by an ensemble of random but rotationally invariant two-body interactions. In the present work we extend these investigations to odd-A and odd-odd nuclei, considering in particular the isospin effects. Studying the realistic shell model as well as the single-j model, we show that random interactions have a tendency to assign the lowest possible total angular momentum and isospin to the ground state. In the sd shell model this reproduces correctly the isospin but not the spin quantum numbers of actual odd-odd nuclei. An odd-even staggering effect in probability of various ground state quantum numbers is present for even-even and odd-odd nuclei, while it is smeared out for odd-A nuclei. The observed regularities suggest the underlying mechanism of bosonlike pairing of fermionic pairs in T=0 and T=1 states generated by the off-diagonal matrix elements of random interactions. The relation to the models of random spin interactions is briefly discussed

Results: Offspring whose mothers had any AR symptoms during early pregnancy showed a significantly higher adjusted odds ratio for the onset of AR in offspring than those whose mothers had no symptoms during pregnancy (adjusted Odds Ratio: 6.26, p=0.036. However, the symptoms of AR during late pregnancy showed no effects on the odds ratio. In contrast, the presence or absence of AR symptoms during early or late pregnancy showed no association with the prevalence of food allergy, atopic dermatitis or asthma in offspring. Conclusions: Our results suggest the presence of possible epigenetic mechanisms regulating the onset of AR in humans presumably through increased organ-specific hypersensitivity.

The study goal was to demonstrate the prevalence and severity of external auditory exostoses (EAEs) in a population of surfers and to examine the relationship between these lesions and the length of time surfed as well as water temperature in which the swimmers surfed. It was hypothesized that subjects who predominantly surfed in colder waters had more frequent and more severe exostoses. Two hundred two avid surfers (91% male and 9% female, median age 17 years) were included in the study. EAEs were graded based on the extent of external auditory canal patency; grades of normal (100% patency), mild (66% to 99% patency), and moderate-severe (surfing habits. There was a 38% overall prevalence of EAEs, with 69% of lesions graded as mild and 31% graded as moderate-severe. Professional surfers (odds ratio 3.8) and those subjects who surfed predominantly in colder waters (odds ratio 5.8) were found to be at a significantly increased risk for the development of EAEs. The number of years surfed was also found to be significant, increasing one's risk for developing an exostosis by 12% per year and for developing more severe lesions by 10% per year. Individuals who had moderate-severe EAEs were significantly more likely to be willing to surf in colder waters than were those who had mild EAEs (odds ratio 4.3). EAEs are more prevalent in cold water surfers, and additional years surfing increase one's risk not only for developing an EAE but also for developing more severe lesions.

Likelihood ratio and posterior odds in forensic genetics: Two sides of the same coin.

It has become widely accepted in forensics that, owing to a lack of sensible priors, the evidential value of matching DNA profiles in trace donor identification or kinship analysis is most sensibly communicated in the form of a likelihood ratio (LR). This restraint does not abate the fact that the posterior odds (PO) would be the preferred basis for returning a verdict. A completely different situation holds for Forensic DNA Phenotyping (FDP), which is aimed at predicting externally visible characteristics (EVCs) of a trace donor from DNA left behind at the crime scene. FDP is intended to provide leads to the police investigation helping them to find unknown trace donors that are unidentifiable by DNA profiling. The statistical models underlying FDP typically yield posterior odds (PO) for an individual possessing a certain EVC. This apparent discrepancy has led to confusion as to when LR or PO is the appropriate outcome of forensic DNA analysis to be communicated to the investigating authorities. We thus set out to clarify the distinction between LR and PO in the context of forensic DNA profiling and FDP from a statistical point of view. In so doing, we also addressed the influence of population affiliation on LR and PO. In contrast to the well-known population dependency of the LR in DNA profiling, the PO as obtained in FDP may be widely population-independent. The actual degree of independence, however, is a matter of (i) how much of the causality of the respective EVC is captured by the genetic markers used for FDP and (ii) by the extent to which non-genetic such as environmental causal factors of the same EVC are distributed equally throughout populations. The fact that an LR should be communicated in cases of DNA profiling whereas the PO are suitable for FDP does not conflict with theory, but rather reflects the immanent differences between these two forensic applications of DNA information.

2017-10-01

To determine the magnitude and determinants of the ratio between prevalence of low vision and prevalence of blindness in rapid assessment of avoidable blindness (RAAB) surveys globally. Standard RAAB reports were downloaded from the repository or requested from principal investigators. Potential predictor variables included prevalence of uncorrected refractive error (URE) as well as gross domestic product (GDP) per capita, health expenditure per capita of the country across World Bank regions. Univariate and multivariate linear regression were used to investigate the correlation between potential predictor variables and the ratio. The results of 94 surveys from 43 countries showed that the ratio ranged from 1.35 in Mozambique to 11.03 in India with a median value of 3.90 (Interquartile range 3.06;5.38). Univariate regression analysis showed that prevalence of URE (p = 0.04), logarithm of GDP per capita (p = 0.01) and logarithm of health expenditure per capita (p = 0.03) were significantly associated with the higher ratio. However, only prevalence of URE was found to be significant in multivariate regression analysis (p = 0.03). There is a wide variation in the ratio of the prevalence of low vision to the prevalence of blindness. Eye care service utilization indicators such as the prevalence of URE may explain some of the variation across the regions.

The ( 7 Li, 5n) and ( 11 B, 5n) reactions have been used to study the high-spin states in the two odd-odd nuclei 150 Eu and 152 Tb. Three decoupled bands have been evidenced in each nucleus belonging to the same configurations [f 7/2]sub(n) [h 11/2]sub(p), [h 9/2]sub(n) [h 11/2 ]sub(p) and [i 13/2]sub(n) [h 11/2]sub(p). The latter one is well developped and improves our knowledge of this system between the spherical and deformed region. The analysis of the collective moment of inertia and transition ratios strongly suggests an increase of the deformation when the rotational frequency increases in these two transitional nuclei 150 Eu and 152 Tb

To characterize older adults in Bogotá with high blood pressure and identify factors associated to this condition within this population. Using data from the Salud, Bienestar y Envejecimiento (SABE) (Health, Well-being and Aging) Bogotá Study, we analyzed community-dwelling adults 60 years and older with hypertension. We estimated the prevalence and used logistic regression models to identify factors associated to hypertension. The overall prevalence for hypertension was 56.9%. Older age (odds ratio [OR] = 1.46, 95% confidence interval [CI] = [1.07, 1.97]), having health insurance (OR = 4.15, CI = [1.95, 8.85]), cardiovascular diseases (ORs between 1.70 and 3.65), and poor self-rated health (OR = 1.57, CI = [1.20,2.06]) significantly increased the odds of hypertension. Most individuals received pharmacologic treatment (93.5%); however, 28.4% of individuals had uncontrolled hypertension. We found a high prevalence of hypertension in our cohort and found that comorbidities and poor self-rated health increase the odds of hypertension. Future studies need to tailor interventions for hypertension management in old age. © The Author(s) 2015.

Magnetic dipole moments of odd-odd lanthanides

Sharma, S.D.; Gandhi, R.

Magnetic dipole moments of odd-odd lanthanides. Collective model of odd-odd nuclei is applied to predict the magnetic dipole moments, (μ) of odd-odd lanthanides. A simplified version of expression for μ based on diagonalisation of Hamiltonian (subsequent use of eigenvectors to compute μ) is developed for cases of ground state as well as excited states using no configuration mixing and is applied to the cases of odd-odd lanthanides. The formulae applied to the eleven (11) cases of ground states show significant improvement over the results obtained using shell model. Configuration mixing and coriolis coupling is expected to cause further improvement in the results. On comparing the earlier work in this direction the present analysis has clarified that in the expression μ the projection factors have different signs for the case I=Ωp - Ωn and I=Ωn - Ωp, and sign of μ is negative in general in the second case while it is positive in all others of spin projection alignments. Although the general expression holds for excited states as well but in lanthanide region, the experimental reports of magnetic dipole moments of excite states (band heads of higher rational sequences) are not available except in case of five (5) neutron resonance states which cannot be handled on the basis of the present approach with no configuration mixing. Although in the present discussion, the model could not be applied to excited states but the systematics of change in its magnitude with increasing spin at higher rational states is very well understood. The particle part supressed under faster rotation of the nuclear core and thus finally at higher spin I, the value μ is given by μ=g c I (same as in case of even-even nuclei). These systematics are to be verified whenever enough data for higher excited states are available. (author). 11 refs

Inverted spin sequences in the spectra of odd-odd nuclei in the 2S-1d and 2P-1f shells

International Nuclear Information System (INIS)

Sharma, Arvind; Sharma, S.D.

1990-01-01

In case of odd-odd nuclei, near magic numbers, there are found inverted sequences as well as few rotational members. In order to explain the unique feature of the spectra of odd-odd nuclei, we have applied modified form of rotational-vibrational model with two parameters A and B. It is found that level orders in inverted as well as in rotational sequences are very well reproduced on the basis of this model. In case of inverted spin sequences, the sign of B is found to be positive. The ratio of B/A is ≅ 10 -2 as compared to its value of the order of 10 -3 in case of even-even and odd-A nuclei. We infer that pair correlations are responsible for these invertions. The simple model applied here worked well to predict these inverted spectra. (author)

We suggest an estimator for the proportional odds cumulative incidence model for competing risks data. The key advantage of this model is that the regression parameters have the simple and useful odds ratio interpretation. The model has been considered by many authors, but it is rarely used...... in practice due to the lack of reliable estimation procedures. We suggest such procedures and show that their performance improve considerably on existing methods. We also suggest a goodness-of-fit test for the proportional odds assumption. We derive the large sample properties and provide estimators...

The objective of this study was to examine: (1) the prevalence of diagnosed Tourette syndrome in Canada by sex in youth (aged 12-17) and adults and (2) socioeconomic factors in this population. The majority of epidemiological studies of tics have focused on children and youth, with few studies describing the prevalence of tics in adult populations. Canadian data on Tourette syndrome prevalence were derived from the Canadian Community Health Survey 2010 and 2011 cycles, a Statistics Canada population-based cross-sectional survey that collects information related to health status. We determined the prevalence of diagnosed Tourette syndrome and examined sociodemographic factors, including age, sex, education, income, employment, and birthplace. Overall, 122,884 Canadians participated in the surveys, with 122 participants diagnosed with Tourette syndrome. The prevalence of Tourette syndrome was higher in males in youth: 6.03 per 1000 (95% confidence interval: 3.24-8.81) in males versus 0.48 per 1,000 (95% confidence interval: 0.05-0.91) in females, with a prevalence risk ratio of 5.31 (95% confidence interval: 2.38-11.81). In adults, the prevalence of Tourette syndrome was 0.89 per 1,000 (95% confidence interval: 0.48-1.29) in males versus 0.44 (95% confidence interval: 0.16.0-0.71) in females, with a prevalence risk ratio of 1.93 (95% confidence interval: 1.21-3.08). After adjusting for age and sex, adults with Tourette syndrome had lower odds of receiving postsecondary education or being employed and higher odds of having income lower than the median and receiving governmental support. Data on the prevalence of Tourette syndrome in adults are scarce because most studies focus on children. Our data demonstrate a decreasing prevalence risk ratio for sex in adults compared to children. A diagnosis of Tourette syndrome is associated with lower education, income, and employment in adulthood. © 2016 International Parkinson and Movement Disorder Society. © 2016

Oppositional defiant disorder (ODD) is characterized by a pattern of negative, defiant, disobedient and hostile behavior toward authority figures. ODD is one of the most frequent reasons for clinical consultation on mental health during childhood and adolescence. ODD has a high morbidity and dysfunction, and has important implications for the future if not treated early. To determine the prevalence of ODD in schoolchildren aged 6-16 years in Castile and Leon (Spain). Population study with a stratified multistage sample, and a proportional cluster design. Sample analyzed: 1,049. Cases were defined according to DSM-IV criteria. An overall prevalence rate of 5.6% was found (95% CI: 4.2%-7%). Male gender prevalence=6.8%; female=4.3%. Prevalence in secondary education=6.2%; primary education=5.3%. No significant differences by gender, age, grade, type of school, or demographic area were found. ODD prevalence without considering functional impairment, such as is performed in some research, would increase the prevalence to 7.4%. ODD cases have significantly worse academic outcomes (overall academic performance, reading, maths and writing), and worse classroom behavior (relationship with peers, respect for rules, organizational skills, academic tasks, and disruption of the class). Castile and Leon has a prevalence rate of ODD slightly higher to that observed in international publications. Depending on the distribution by age, morbidity and clinical dysfunctional impact, an early diagnosis and a preventive intervention are required for health planning. Copyright © 2013 SEP y SEPB.

Full Text Available To find out the prevalence and relationship of anemia in reproductive age women in rural area of Tabas, center of Iran. Iron deficiency anemia is the most common nutritional problem, affecting about 41.8% of pregnant and 30.2% of non-pregnant women worldwide.A cross-sectional study was conducted on the random sample of 382 reproductive age women in rural areas of Tabas in March 2010. Independent sample t-test, one way analysis of variance (ANOVA and logistic regression were applied for the data analysis.The obtained data revealed a total response rate of 13.8% for prevalence of anemia, while 14.5% and 5.9% belonged to non-pregnant and pregnant participants, respectively. Low socioeconomic status (odds ratio 3.35 and high parity index (odds ratio 2.31 were associated with higher prevalence of anemia.Although this study was conducted in a rural area of Tabas, where their average incomes were lower than average income of major cities in Iran, the prevalence of anemia was lower than the rate reported in previous studies carried out in other locations of Iran, even in high risk (pregnant women groups.

The results from the Coulex experiments accomplished at REX-ISOLDE after its upgrade to 3 MeV/u during the last year have shown the power of this method and its importance in order to obtain information on the collective properties of even-even nuclei. Performing an experiment on the odd-mass and on the odd-odd neutron-rich Cu isotopes in the vicinity of N=40 should allow us to determine and interpret the effective proton and neutron charges in the region and to unravel the lowest proton-neutron multiplets in $^{68,70}$Cu. This experiment can take the advantage of the unique opportunity to accelerate isomerically separated beams using the RILIS ion source at ISOLDE.

It is well established that neural activity is stochastically modulated over time. Therefore, direct comparisons across experimental conditions and determination of change points or maximum firing rates are not straightforward. This study sought to compare temporal firing probability curves that may vary across groups defined by different experimental conditions. Odds-ratio (OR) curves were used as a measure of comparison, and the main goal was to provide a global test to detect significant differences of such curves through the study of their derivatives. An algorithm is proposed that enables ORs based on generalized additive models, including factor-by-curve-type interactions to be flexibly estimated. Bootstrap methods were used to draw inferences from the derivatives curves, and binning techniques were applied to speed up computation in the estimation and testing processes. A simulation study was conducted to assess the validity of these bootstrap-based tests. This methodology was applied to study premotor ventral cortex neural activity associated with decision-making. The proposed statistical procedures proved very useful in revealing the neural activity correlates of decision-making in a visual discrimination task. Copyright © 2011 John Wiley & Sons, Ltd.

This review provides a meta-analysed male:female prevalence ratio of oppositional defiant disorder (ODD) during middle childhood in non-referred children. It also analyses sex differences in prevalence across cultures and over time. A systematic search for studies via the following sources was conducted: PsycInfo, Web of Knowledge, Medline Complete, Scopus, EMBASE, InfoRMIT, Psychological and Behavioural Sciences Collection, Cochrane Library, PubMed and ProQuest Health. The studies presented in two previous systematic reviews were also added to the search results. Inclusion/exclusion criteria were then applied and final studies were appraised for their methodological quality. Nineteen independent effect sizes met full inclusion criteria (aggregated sample N = 44,107). Overall, the prevalence of ODD was significantly higher in boys than girls (RR = 1.59, 95 % CI [1.36, 1.86], p  0.05). Sex differences in prevalence were significant in studies published prior to and post the year 2000 (RR = 1.57, 95 % CI [1.22, 2.02], p  0.05). The sex differences in ODD prevalence are discussed within the context of (i) predominant theories of sex differences in externalising behaviours, and (ii) departure from the sex-differences pattern found for other disruptive behavioural disorders.

To estimate the prevalence of major depressive disorder (MDD) among spouses of men who use alcohol in two rural areas in Sri Lanka, and to examine whether the severity of alcohol-related problems (ARPs) in men and presence of alcohol-related domestic violence are associated with MDD among these women. In a cross-sectional study, ARPs among men were assessed using Alcohol Use Disorders Identification Test (AUDIT) questionnaire filled in by men, and domestic violence and husbands' drinking pattern data obtained from the women. MDD among the women was ascertained using the Structured Clinical Interview for DSM-IV Disorders for major depression. Using logistic regression we examined whether age, past history of depression, different indices of ARPs and domestic violence were associated with current MDD among the women. Point prevalence of MDD in the sample was 33.3% (95% CI: 25.93, 40.73%). Once adjusted for other factors, morning drinking of the spouse (odds ratio = 4.11, 95% CI: 1.25, 13.47; P = 0.019) and increasing age (odds ratio = 1.05, 95% CI: 1.01, 1.09; P = 0.003) significantly increased the odds of MDD. Being subjected to domestic violence/arguments also had a trend to be associated with MDD among women, but was not significant (odds ratio = 2.29, 95% CI: 0.95, 5.48; P = 0.062). The prevalence of MDD among spouses of men who use alcohol is markedly higher than that has been observed among Sri Lankan women in previous studies. The prevalence of MDD in women seems to increase when their husbands are morning drinkers, and with increasing age. © The Author 2015. Medical Council on Alcohol and Oxford University Press.

The purpose of this study was to determine the association between different ethnic groups and the prevalence, awareness, and control of diabetes in Malaysia. A population-based cross-sectional study using multistage sampling was conducted in Malaysia. Diabetes is defined as having a fasting blood glucose > or =7 mmol/L or a self-reported diabetic on treatment. Among the 7683 respondents aged > or =30 years, the prevalence of diabetes mellitus was 15.2% (95% CI = 14.1, 16.4). Multivariate analysis showed that compared with Malays, Chinese had lower odds (adjusted odds ratio [aOR] 0.71; 95% CI = 0.56, 0.91) and Indians had higher odds of having diabetes (aOR 1.54; 95% CI = 1.20, 1.98). The odds of diabetes increased with age, family history of diabetes, body mass index, and lower education levels. Among those with diabetes mellitus, 45.0% were aware and 42.7% were under treatment. Among treated diabetics, 25.1% had their fasting blood sugar under control. There is a significant association between prevalence of diabetes and different ethnic groups.

The aim of the present study was to evaluate the association between waist circumference and the prevalence/control of hypertension in an urban elderly population. From September 2009 to June 2010, a population-based cross-sectional study was conducted in Wanshoulu area of Beijing, China. A total of 2 035 elderly (828 male, 1 207 females) participants aged ≥60 years from a community were included in this study for data analysis. We found that the increased waist circumference could significantly increase the risk of prevalence and poor control of hypertension, with the adjusted odds ratios (95% CI) as 1.04 (1.01-1.08) and 0.96 (0.92-1.00) , respectively. Among those identified pure central obesity females (64.7%) , the prevalence of hypertension was significantly higher than those females with normal body mass index (BMI) or with normal waist circumference (52.2%). The adjusted odds ratio (95%CI) between the above said groups appeared as 1.58 (1.07-2.32). The control rate of hypertension among females (32.9%) with pure central obesity, was lower than that of the females with normal BMI and waist circumference (43.5%) , with an adjusted odds ratio (95%CI) as 0.62 (0.37-1.04, P=0.071). There appeared significant association between people with pure central obesity and the increased risk of prevalence or with poor control of hypertension. More attention should be paid to both the prevalence and control of hypertension programs among females with pure central obesity.

Full Text Available Brazil is characterized by a concentrated AIDS epidemic, it has a prevalence of less than 1% in the general population. However, there are higher rates in specific populations, especially in men who have sex with men. The study's aim was to analyze the association between sociodemographic characteristics, sexual practices, sexual behaviors and the HIV infection in a group of men who have sex with men. Secondary data was collected between June 2014 and September 2015 in a research of cross-sectional design in the city of Rio de Janeiro, Brazil. Volunteers answered an online computerized questionnaire and took HIV test. Chi-squared distribution and multiple logistic regression was used. There were 341 participants. Most of them were racially mixed, single, average age of 30.6 years and with a higher education level. The HIV prevalence was 13.9%. Two logistic models were fit (insertive or receptive anal intercourse. Both models showed an association with HIV among those who had a HIV positive sexual partner (Odds Ratio ≈ 2.5 and a high self-perception of acquiring HIV (Model 1: Odds Ratio ≈ 7/Model 2: Odds Ratio ≈ 10. Low condom usage in receptive anal intercourse with casual partners had a direct association with HIV seropositivity, whereas insertive anal intercourse with casual partners with or without condoms were inversely related. The study identified a high prevalence of HIV infections among a group of men who sex with men with a high self-perception risk of acquiring HIV. The findings also showed a relation with sociodemographic and sexual behavior variables.

It is often observed that pain causes substantial problems for nursing home residents. However, there has been little research about the prevalence of pain for nursing home residents in Japan. This study aimed to examine the prevalence of pain in older adults living in nursing homes in Japan by using self-reporting and the Abbey Pain Scale-Japanese version (APS-J) and to explore factors related to pain. This is a descriptive study. Residents in two Special Nursing Homes for the Elderly in Tokyo, Japan, were asked to participate in this study, with the exclusion of short-term temporary residents. Data collected from participating residents included their demographics and the results from the Barthel Index, the Folstein Mini-Mental State Examination, the APS-J, and the Verbal Descriptor Scale for pain. The residents were divided into two groups: residents able to report their pain (self-report group) and residents not able to report their pain. The second group was assessed by using the APS-J (APS-J group). The Mann-Whitney U test, the χ2 test, and logistic analyses were performed to derive factors related to pain prevalence. Data were obtained from 171 residents. The prevalence of pain in the self-report group (n = 96) was 41.7%. For the 75 residents unable to report their pain, 52.0% were assessed by the APS-J to have pain. The overall pain prevalence of all residents was 46.2%. Age, Barthel Index score, and length of time of institutionalization were significantly associated with residents' pain in the APS-J group. Logistic regression analysis showed that contracture (odds ratio 3.8) and previous injury (odds ratio 3.4) were associated with residents' pain in the self-report group, whereas only the length of nursing home stay (odds ratio 1.03) was a predictor for pain in the APS-J group. Nearly one-half of residents had pain when they moved or were moved. Pain assessment and management is needed for residents. Copyright © 2013 American Society for Pain

To assess the trend of sex disparity in hemoglobin concentration and prevalence of anemia among Chinese school-aged children from 1995 to 2010. Data were collected from 360 866 children aged 7, 9, 12, 14, and 17 years during 4 cross-sectional surveys (1995, 2000, 2005, and 2010) of the Chinese National Surveys on Students Constitution and Health. Shifts in hemoglobin concentration distributions were compared by sex. Average shifts and sex differences were calculated with quantile regression models. Logistic regression was used to estimate the prevalence odds ratio of sex for prevalence of anemia in different surveys. The mean hemoglobin concentration increased among Chinese children between 1995 and 2010, from 132.7 to 138.3 g/L in boys, and from 127.7 to 132.3 g/L in girls. The prevalence of anemia decreased from 18.8% in 1995 to 9.9% in 2010. It was higher in rural than urban children among all age groups. The prevalence odds ratios of girls versus boys for anemia increased in both urban and rural areas over time. Hemoglobin concentration and prevalence of anemia improved among Chinese school-aged children over time. Hemoglobin concentration improved faster in boys than girls and as a result the relative prevalence of anemia in girls compared with boys increased. Sex-specific preventive guidelines and public health policies for childhood anemia are needed in China. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available Sirijit Suttajit, Sutrak PilakantaDepartment of Psychiatry, Faculty of Medicine, Chiang Mai University, Chiang Mai, ThailandPurpose: To identify the point prevalence of metabolic syndrome in patients with schizophrenia and to evaluate the association between depressive symptoms and metabolic syndrome in patients with schizophrenia.Patients and methods: Metabolic syndrome was assessed based on an updated definition derived from the modified National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III and the International Diabetes Federation criteria. The 17-item Hamilton Depression Rating Scale (HDRS-17 was used to measure depressive symptoms in 80 patients with schizophrenia. Odds ratios and 95% confidence intervals were calculated using logistic regression for the association between each depressive symptom and metabolic syndrome.Results: The point prevalence rates of metabolic syndrome according to the modified NCEP-ATP III and International Diabetes Federation criteria were 37% and 35%, respectively. The risk of having metabolic syndrome significantly increased in those who were widowed or separated, or had longer duration of illness. Central obesity was the metabolic feature with the highest odds ratios for metabolic syndrome at 19.3. Three out of 17 items of HDRS subscales were found to be significantly associated with metabolic syndrome, including depressed mood, middle insomnia, and retardation with the odds ratios of 3.0, 3.4, and 3.6, respectively.Conclusion: This study showed that the prevalence of metabolic syndrome in patients with schizophrenia was higher than the overall rate but was slightly lower than in the general population in the USA. Central obesity, measured by waist circumference, was found to be highly correlated with metabolic syndrome. Depressed mood, middle insomnia, and retardation were significantly associated with metabolic syndrome in patients with schizophrenia. Waist circumference and screening

The human T-cell lymphotropic virus type 1 (HTLV-1) was the first human retrovirus known as a direct causal agent of a malignant disease. The vertical route of HTLV transmission is the most frequent pathway of the virus contamination. This study was performed to determine the prevalence ratio of HTLV-1 infection among nursing women. From January 2004 to January 2005, blood samples from 1033 nursing mothers from Paraíba, Brazil were evaluated for HTLV antibodies by ELISA and HTLV-1 viral particles confirmed by polymerase chain reaction (PCR). HTLV antibodies were detected in 7 women. The overall seroprevalence ratio was 0.68% and HTLV-1 viral sequences were confirmed by PCR in 2 women. These preliminary data suggest that HTLV screening should be introduced as a mandatory test before breastfeeding and breast milk donation in Paraíba, Brazil. Additionally, counseling programs would help reduce the prevalence ratio of HTLV-1 infected individuals in this Brazilian region.

We aimed to describe the prevalence and age distribution of personality disorders and their comorbidity with other psychiatric disorders in an age-stratified sample of Australian women aged ⩾25 years. Individual personality disorders (paranoid, schizoid, schizotypal, histrionic, narcissistic, borderline, antisocial, avoidant, dependent, obsessive-compulsive), lifetime mood, anxiety, eating and substance misuse disorders were diagnosed utilising validated semi-structured clinical interviews (Structured Clinical Interview for DSM-IV-TR Axis I Disorders, Research Version, Non-patient Edition and Structured Clinical Interview for DSM-IV Axis II Personality Disorders). The prevalence of personality disorders and Clusters were determined from the study population ( n = 768), and standardised to the Australian population using the 2011 Australian Bureau of Statistics census data. Prevalence by age and the association with mood, anxiety, eating and substance misuse disorders was also examined. The overall prevalence of personality disorders in women was 21.8% (95% confidence interval [CI]: 18.7, 24.9). Cluster C personality disorders (17.5%, 95% CI: 16.0, 18.9) were more common than Cluster A (5.3%, 95% CI: 3.5, 7.0) and Cluster B personality disorders (3.2%, 95% CI: 1.8, 4.6). Of the individual personality disorders, obsessive-compulsive (10.3%, 95% CI: 8.0, 12.6), avoidant (9.3%, 95% CI: 7.1, 11.5), paranoid (3.9%, 95% CI: 3.1, 4.7) and borderline (2.7%, 95% CI: 1.4, 4.0) were among the most prevalent. The prevalence of other personality disorders was low (⩽1.7%). Being younger (25-34 years) was predictive of having any personality disorder (odds ratio: 2.36, 95% CI: 1.18, 4.74), as was being middle-aged (odds ratio: 2.41, 95% CI: 1.23, 4.72). Among the strongest predictors of having any personality disorder was having a lifetime history of psychiatric disorders (odds ratio: 4.29, 95% CI: 2.90, 6.33). Mood and anxiety disorders were the most common comorbid

This work aims to study the associations, if any, of hyperuricemia, gout, and menopause status in the US population. Using multiyear data from the National Health and Nutrition Examination Survey, we performed unmatched comparisons and one to three age-matched comparisons of women aged 20 to 70 years with and without hyperuricemia (serum urate ≥6 mg/dL). Analyses were performed using survey-weighted multiple logistic regression and conditional logistic regression, respectively. Overall, there were 1,477 women with hyperuricemia. Age and serum urate were significantly correlated. In unmatched analyses (n = 9,573 controls), postmenopausal women were older, were heavier, and had higher prevalence of renal impairment, hypertension, diabetes, and hyperlipidemia. In multivariable regression, after accounting for age, body mass index, glomerular filtration rate, and diuretic use, menopause was associated with hyperuricemia (odds ratio, 1.36; 95% CI, 1.05-1.76; P = 0.002). In corresponding multivariable regression using age-matched data (n = 4,431 controls), the odds ratio for menopause was 0.94 (95% CI, 0.83-1.06). Current use of hormone therapy was not associated with prevalent hyperuricemia in both unmatched and matched analyses. Age is a better statistical explanation for the higher prevalence of hyperuricemia among older women than menopause status.

A total of 1,092 dairy goats from 110 flocks randomly selected in the county of Monteiro, Paraíba state, during March 2009 to March 2010, were used. In each selected flock a epidemiological questionnaire was applied to verify the occurrence of possible factors that could be associated with the flock-level prevalence. For the serological diagnosis of Pestivirus infection the serum neutralization test, using the BVDV-1 NADL strain, was carried out. Flock-level prevalence was 6.36% (95% CI = 2.60% – 12.67% and animal-level prevalence was 0.82% (95% CI = 0.38% – 1.56%. Not to perform vermifugation (odds ratio = 10.49; p = 0.035 and to perform navel cut and disinfection (odds ratio = 12.73; p = 0.034 were identified as risk factors. These results indicate viral circulation in dairy goats in the semiarid region of the Paraíba state.

AIM: Pressure ulceration is a significant, but preventable, cause of morbidity and resource utilisation in hospital populations. Data on pressure ulcer prevalence in Ireland are limited. This study aims to determine (i) the point-prevalence of pressure ulcers in three teaching hospitals in Ireland and (ii) risk factors for their development. METHODS: Eight teams of one doctor and one nurse visited 672 adult patients over a 2-day period in three teaching hospitals. Each patient was examined and pressure ulcers graded with the European Pressure Ulcer Advisory Panel system. Mental test score, Barthel index, type of support surface, length of stay, documentation of risk assessment and serum albumin were recorded. RESULTS: Point-prevalence of pressure ulceration was 18.5%. Seventy-seven percent of pressure ulcers were hospital-acquired, 49% grade 1, 37% grade 2, 11% grade 3 and 3% grade 4. Reduced mobility, urinary incontinence, cognitive impairment, low serum albumin and length of stay were significantly associated with pressure ulcers. Multivariate logistic regression analysis found reduced mobility (odds ratio 8.84; 95% CI 5.04-15.48, p<0.0001) and length of stay (odds ratio 1.02; 95% CI 1.01-1.02, p<0.0001) to be predictive of the presence of pressure ulcers. Age, gender and risk assessment documentation were not associated with pressure ulcers. Sixty-five percent of patients with pressure ulcers were positioned on appropriate support surfaces. DISCUSSION: Point-prevalence of pressure ulceration was 18.5%, similar to international data. Regular audit of prevalence, prevention and management strategies may raise awareness, influence resource allocation and ultimately improve patient care.

To describe the associations between socio-economic position and prevalent tuberculosis in the 2010 ZAMSTAR Tuberculosis Prevalence Survey, one of the first large tuberculosis prevalence surveys in Southern Africa in the HIV era. The main analyses used data on 34 446 individuals in Zambia and 30 017 individuals in South Africa with evaluable tuberculosis culture results. Logistic regression was used to estimate adjusted odds ratios for prevalent TB by two measures of socio-economic position: household wealth, derived from data on assets using principal components analysis, and individual educational attainment. Mediation analysis was used to evaluate potential mechanisms for the observed social gradients. The quartile with highest household wealth index in Zambia and South Africa had, respectively, 0.55 (95% CI 0.33-0.92) times and 0.70 (95% CI 0.54-0.93) times the adjusted odds of prevalent TB of the bottom quartile. College or university-educated individuals in Zambia and South Africa had, respectively, 0.25 (95% CI 0.12-0.54) and 0.42 (95% CI 0.25-0.70) times the adjusted odds of prevalent TB of individuals who had received only primary education. We found little evidence that these associations were mediated via several key proximal risk factors for TB, including HIV status. These data suggest that social determinants of TB remain important even in the context of generalised HIV epidemics. © 2018 The Authors.

Objectives To ascertain the prevalence of Helicobacter pylori in patients with gastro-oesophageal reflux disease and its association with the disease. Design Systematic review of studies reporting the prevalence of H pylori in patients with and without gastro-oesophageal reflux disease. Data sources Four electronic databases, searched to November 2001, experts, pharmaceutical companies, and journals. Main outcome measure Odds ratio for prevalence of H pylori in patients with gastro-oesophageal reflux disease. Results 20 studies were included. The pooled estimate of the odds ratio for prevalence of H pylori was 0.60 (95% confidence interval 0.47 to 0.78), indicating a lower prevalence in patients with gastro-oesophageal reflux disease. Substantial heterogeneity was observed between studies. Location seemed to be an important factor, with a much lower prevalence of H pylori in patients with gastro-oesophageal reflux disease in studies from the Far East, despite a higher overall prevalence of infection than western Europe and North America. Year of study was not a source of heterogeneity. Conclusion The prevalence of H pylori infection was significantly lower in patients with than without gastro-oesophageal reflux, with geographical location being a strong contributor to the heterogeneity between studies. Patients from the Far East with reflux disease had a lower prevalence of H pylori infection than patients from western Europe and North America, despite a higher prevalence in the general population. What is already known on this topicThe relation between H pylori infection and gastro-oesophageal reflux disease is controversialStudies on the prevalence of H pylori in patients with gastro-oesophageal reflux disease have given conflicting resultsRecent guidelines recommend eradication of H pylori in patients requiring long term proton pump inhibitors, essentially for reflux diseaseWhat this study addsDespite heterogeneity between studies, the prevalence of H pylori was

Hepatitis C virus (HCV) infection is highly prevalent among prisoners and this prevalence estimates reach 64% among prisoners who inject illicit drugs. Prisons are important sites for HCV transmission in the absence of access to sterile injecting equipment; hence, it can be transmitted between prisoners who share contaminated needles and syringes. We aimed to estimate the prevalence of risk factors for anti-HCV prevalence, with particular interest on injecting behavior, and to assess correlates of anti-HCV positivity among Mexico City prisoners. Cross-sectional study based on information -collected in three male and two female prisons in Mexico City during 2010-2011- about sexually transmitted infections, socio-demographics, criminal history, substance use, vitamin injection, tattooing, among others (n=3,910). Weighted multivariable adjusted logistic regression models were estimated to assess the overall and differential odds for anti-HCV due to injecting behavior. Overall prevalence of anti-HCV was 3.3%. This figure rose to 43.1% among prisoners with a history of illicit drug injection. Prisoners with history of vitamin injection showed a similar prevalence of anti-HCV (43.8%). After stratifying by substance injected, the adjusted odds ratio was 9.8 (95% CI: 4.0, 23.8) for illicit drug injection and 11.9 (95% CI: 5.8, 23.8) for illicit drug and vitamin injection. Based on data from the most populous prisons in Mexico City, this study showed that anti-HCV is highly prevalent among prisoners with history of injecting behavior. In this sense, injecting behavior per-se, independent of the substance used, is associated with increased odds of anti-HCV positivity. Copyright © 2017 Elsevier B.V. All rights reserved.

Full Text Available Introduction: Clinical evaluation of iodine deficiency disorders (IDDs is often accomplished by assessment of urinary iodine excretion (UIE in random samples; however, the utilization of 24 hour urine samples is a more reliable biomarker of nutritional iodine status. This study was designed to evaluate total goiter prevalence (TGP and iodine/creatinine ratio among school-aged children in Urmia County. Methods: Schoolchildren (n=500 were recruited by cluster sampling from different educational areas in Urmia County. Goiter prevalence was assessed by thyroid palpation, UIE was determined by Sandell-Koltoff reaction, and Urinary creatinine was measured by the Jaffe-method. Results: In general, TGP was 12.2%. Among these, there were 48 individuals (9.6% with grade I goiter and 13 subjects (2.6% with grade II goiter. Mean urinary creatinine, median UIE and median I/Cr ratio were respectively 1.36±0.76 mg/dL, 14.3µg/dL, and 11.5µg/mg. Prevalence of iodine deficiency according to UIE criteria was 22.8% and that of I/Cr ratio was 41.2%. There was a correlation between age and UIE (P=001; r=0.163. UIE and urinary creatinine were correlated as well (P<0.003; r= 0.133. A correlation was also detected between I/Cr ratios and UIE (P=0.003; r=0.133 whilst a negative association was seen between age and I/Cr ratios (P=0.001; and r=–0.263. Conclusion: This investigation reconfirms that there is slight-to-mild iodine deficiency in Urmia County. The utilization of I/Cr ratio in conjugation with UIE and palpation may provide a better assessment in investigating nutritional iodine status.

Valores de referência para estimativas por ponto e por intervalo para as razões de prevalência (RP foram obtidos pelo método de estratificação de Mantel-Haenszel. Estimativas ajustadas foram calculadas utilizando regressões de Cox e Poisson com variância robusta, e regressão log-binomial. Odds ratios (OR brutos e ajustados foram obtidos pela regressão logística. RESULTADOS: As estimativas por ponto e por intervalo obtidas pelas regressões de Cox e Poisson foram semelhantes à obtida pela estratificação de Mantel-Haenszel, independentemente da prevalência do desfecho e das covariáveis do modelo. O modelo log-binomial apresentou dificuldade de convergência quando o desfecho tinha prevalência alta e havia covariável contínua no modelo. A regressão logística produziu estimativas por ponto e por intervalo maiores do que as obtidas pelos outros métodos, principalmente para os desfechos com maiores prevalências iniciais. Se interpretados como estimativas de RP, os OR superestimariam as associações para os desfechos com prevalência inicial baixa, intermediária e alta em 13%, quase 100% e quatro vezes mais, respectivamente. CONCLUSÕES: Em análise de dados de estudos de corte transversal, os modelos de Cox e Poisson com variância robusta são melhores alternativas que a regressão log

Full Text Available Functional constipation is very common with heterogeneous symptoms that have substantial impact on patient quality of life as well as medical resources which are rarely reported as life-threatening. The aim of this study is to examine the prevalence and symptoms characteristic of functional constipation (FC by using Rome III diagnostic criteria among tertiary education students with an intention to introduce treatment in the future.Demographic, socio-economics characteristics and symptoms of FC using the Rome III criteria were sought using a questionnaire administered to Malaysian students in a tertiary education setting. Other data obtained were the general health status, lifestyle factors and anthropometric measurements. Using a simple random sampling method, a total of 1662 students were recruited in the study with a response rate of 95.0%. Sampled data are presented as frequency and percentage and stratified accordingly into categories for Chi-square analysis.The prevalence of functional constipation among the students was 16.2%, with a significantly higher prevalence among women (17.4% than men (12.5%. Hard or lumpy stool, incomplete evacuation, anorectal obstruction and straining were reported as the commonest symptoms experienced. Type 3 was the most frequent stool consistency experienced among the constipated individuals (35.2%. Only 4.4% of individuals reported having less than three defecations per week. Using univariable analysis, FC was significantly associated with sex (odds ratio: 1.48, 95% CI: 1.06-2.06 and age group (odds ratio: 1.34, 95% CI: 1.01-1.79 with P value < 0.05 significance level. In multivariate logistic regression analysis, only sex was found significantly associated with FC (adjusted odds ratio: 1.53, 95% CI: 1.08-2.17, P < 0.05.Based on the prevalence rate, constipation is a common problem among tertiary education students (16.2%, with significantly more prevalence among the female respondents.

Full Text Available Lymphoma is a common haematopoietic neoplasm in dogs. Several breeds have been shown to have a predisposition to lymphoma; however, very little information exists regarding the South African dog population. This study assessed whether any breed had increased odds of developing lymphoma compared with others, and also investigated the effects of age, sex and neutering status on disease prevalence. Two study populations and their corresponding reference populations were studied retrospectively. Odds ratios (ORs for lymphoma in 49 dog breeds, together with their 95% confidence intervals (CI, were calculated. Age effect was assessed by calculating ORs for different age categories in one of the populations. The chi-square test was used to evaluate differences in the prevalence of the various sex and neutering categories in one lymphoma population compared with its reference population. Fourteen breeds had significantly increased odds of developing lymphoma, and one breed had significantly decreased odds (p < 0.050. The median ages of the two lymphoma populations were 6.5 and 8.0 years, with the 6.1–9.0 year category having significantly increased odds of developing lymphoma (OR 1.61, CI 1.2–2.16, p = 0.002. In one of the lymphoma populations, higher proportions of males (p = 0.033 and neutered females (p = 0.006 were found when compared with the reference population. These findings suggest that certain breeds in South Africa have a higher risk of developing lymphoma, and that sex hormones may play a role in lymphoma pathogenesis. The findings may provide useful information for pet owners and veterinarians.

Full Text Available Abstract Background Case descriptions suggest IBS patients are more likely to have other disorders, including migraine, fibromyalgia, and depression. We sought to examine the prevalence of these conditions in cohorts of people with and without IBS. Methods The source of data was a large U.S. health plan from January 1, 1996 though June 30, 2002. We identified all people with a medical claim associated with an ICD-9 code for IBS. A non-IBS cohort was a random sample of people with an ICD-9 code for routine medical care. In the cohorts, we identified all claims for migraine, depression, and fibromyalgia. We estimated the prevalence odds ratios (PORs of each of the three conditions using the Mantel-Haenszel method. We conducted quantitative sensitivity analyses to quantify the impact of residual confounding and in differential outcome identification. Results We identified 97,593 people in the IBS cohort, and a random sample of 27,402 people to compose the non-IBS comparison cohort. With adjustment, there was a 60% higher odds in the IBS cohort of having any one of the three disorders relative to the comparison cohort (POR 1.6, 95% CI 1.5 – 1.7. There was a 40% higher odds of depression in the IBS cohort (POR 1.4, 95% CI 1.3 – 1.4. The PORs for fibromyalgia and migraine were similar (POR for fibromyalgia 1.8, 95% CI 1.7 – 1.9; POR for migraine 1.6, 95% CI 1.4 – 1.7. Differential prevalence of an unmeasured confounder, or imperfect sensitivity or specificity of outcome detection would have impacted the observed results. Conclusion People in the IBS cohort had a 40% to 80% higher prevalence odds of migraine, fibromyalgia, and depression.

In Mexico there is little research to know the magnitude of mobbing. To identify the prevalence of mobbing and characteristics associated in workers. A cross-sectional study of 499 workers who use medical unit. A questionnaire was used to determine the presence of mobbing and various instruments to know the personality, vulnerability to stress, self-esteem and depression. Prevalence odds ratio, dispersion, chi-square and Poisson regression were calculated. A prevalence of 36% was found; no significant differences between sex or school level in mobbing presence, 20.2%, were found. Sixty per cent women are perceived as victims of harassment high relative to men (p = 0.04). Workers with low self-esteem have a greater association with high mobbing (p mobbing and personality and emotional disorders were identified.

When outcomes are binary, the c-statistic (equivalent to the area under the Receiver Operating Characteristic curve) is a standard measure of the predictive accuracy of a logistic regression model. An analytical expression was derived under the assumption that a continuous explanatory variable follows a normal distribution in those with and without the condition. We then conducted an extensive set of Monte Carlo simulations to examine whether the expressions derived under the assumption of binormality allowed for accurate prediction of the empirical c-statistic when the explanatory variable followed a normal distribution in the combined sample of those with and without the condition. We also examine the accuracy of the predicted c-statistic when the explanatory variable followed a gamma, log-normal or uniform distribution in combined sample of those with and without the condition. Under the assumption of binormality with equality of variances, the c-statistic follows a standard normal cumulative distribution function with dependence on the product of the standard deviation of the normal components (reflecting more heterogeneity) and the log-odds ratio (reflecting larger effects). Under the assumption of binormality with unequal variances, the c-statistic follows a standard normal cumulative distribution function with dependence on the standardized difference of the explanatory variable in those with and without the condition. In our Monte Carlo simulations, we found that these expressions allowed for reasonably accurate prediction of the empirical c-statistic when the distribution of the explanatory variable was normal, gamma, log-normal, and uniform in the entire sample of those with and without the condition. The discriminative ability of a continuous explanatory variable cannot be judged by its odds ratio alone, but always needs to be considered in relation to the heterogeneity of the population.

We measured the prevalence of active epilepsy and investigated the treatment gap and treatment gap risk profile in eastern China. This was a cross-sectional population-based survey conducted in Zhejiang, China, from October 2013 to March 2014. A total 54,976 people were selected using multi-stage cluster sampling. A two-stage questionnaire-based process was used to identify patients with active epilepsy and to record their demographic, socioeconomic, and epilepsy-related features. Logistic regression analysis was used to analyze risk factors of the treatment gap in eastern China, as adjusted for age and sex. We interviewed 50,035 people; 118 had active epilepsy (2.4‰), among which the treatment gap was 58.5%. In multivariate analysis, failure to receive appropriate antiepileptic treatment was associated with higher seizure frequency of 12-23 times per year (adjusted odds ratio=6.874; 95% confidence interval [CI]=2.372-19.918), >24 times per year (adjusted odds ratio=19.623; 95% CI=4.999-77.024), and a lack of health insurance (adjusted odds ratio=7.284; 95% CI=1.321-40.154). Eastern China has relatively lower prevalence of active epilepsy and smaller treatment gap. Interventions aimed at reducing seizure frequency, improving the health insurance system should be investigated as potential targets to further bridge the treatment gap.

To report prevalence, risk factors and clinical outcomes for presumptive gastric dilation-volvulus diagnosed among an emergency-care population of UK dogs. The study used a cross-sectional design using emergency-care veterinary clinical records from the VetCompass Programme spanning September 1, 2012 to February 28, 2014 and risk factor analysis using multivariable logistic regression modelling. The study population comprised 77,088 dogs attending 50 Vets Now clinics. Overall, 492 dogs had presumptive gastric dilation-volvulus diagnoses, giving a prevalence of 0·64% (95% Confidence interval: 0·58 to 0·70%). Compared with cross-bred dogs, breeds with the highest odds ratios for the diagnosis of presumptive gastric dilation-volvulus were the great Dane (odds ratio: 114·3, 95% Confidence interval 55·1 to 237·1, Pdogs aged up to 12 years and neutered male dogs had 1·3 (95% Confidence interval 1·0 to 1·8, P=0·041) times the odds compared with entire females. Of the cases that were presented alive, 49·7% survived to discharge overall, but 79·3% of surgical cases survived to discharge. Approximately 80% of surgically managed cases survived to discharge. Certain large breeds were highly predisposed. © 2017 British Small Animal Veterinary Association.

An observational study of 790 to over 3,000 herds was conducted to estimate the within-herd prevalence and cow-level risk factors for ketosis in dairy cattle in herds that participate in a Dairy Herd Improvement Association (DHIA) program. Ketosis or hyperketolactia (KET) was diagnosed as milk β-hydroxybutyrate ≥0.15 mmol/L at first DHIA test when tested within the first 30 d in milk. Seven hundred ninety-five herds providing at least 61 first milk tests from June 2014 to December 2015 were used to estimate the provincial within-herd prevalence of KET. All herds on DHIA in Ontario (n = 3,042) were used to construct cow-level multilevel logistic regression models to investigate the association of DHIA collected variables with the odds of KET at first DHIA milk test. Primiparous and multiparous animals were modeled independently. The cow-level KET prevalence in Ontario was 21%, with an average within-herd prevalence of 21% (standard deviation = 10.6) for dairy herds enrolled in a DHIA program. The prevalence of KET had a distinct seasonality with the lowest prevalence occurring from July to November. Automatic milking systems (AMS) were associated with increased within-herd prevalence, as well as increased odds of KET in multiparous animals at first test (odds ratio: 1.45; 95% confidence interval: 1.30 to 1.63). Jersey cattle had over 1.46 times higher odds of KET than Holstein cattle. Milk fat yield ≥1.12 kg/d at the last test of the previous lactation was associated with decreased odds of KET in the current lactation (odds ratio: 0.56; 95% confidence interval: 0.53 to 0.59). Increased days dry and longer calving intervals, for multiparous animals, and older age at first calving for primiparous animals increased the odds of KET at first test. This study confirms previous findings that increased days dry, longer calving intervals, and increased age at first calving are associated with increased odds of KET and is the first report of increased KET in herds with

To determine the prevalence and distribution of abnormal plasma liver enzymes in a representative sample of older adults with Type 2 diabetes. Plasma concentrations of alanine aminotransferase, aspartate aminotransferase and γ-glutamyltransferase were measured in a randomly selected, population-based cohort of 1066 men and women aged 60-75 years with Type 2 diabetes (the Edinburgh Type 2 Diabetes Study). Overall, 29.1% (95% CI 26.1-31.8) of patients had one or more plasma liver enzymes above the upper limit of the normal reference range. Only 10.1% of these patients had a prior history of liver disease and a further 12.4% reported alcohol intake above recommended limits. Alanine aminotransferase was the most commonly raised liver enzyme (23.1% of patients). The prevalence of abnormal liver enzymes was significantly higher in men (odds ratio 1.40, 95% CI 1.07-1.83), in the youngest 5-year age band (odds ratio 2.02, 95% CI 1.44-2.84), in patients with diabetes duration enzyme abnormality. The prevalence of elevated liver enzymes in people with Type 2 diabetes is high, with only modest variation between clinically defined patient groups. Further research is required to determine the prognostic value of raised, routinely measured liver enzymes to inform decisions on appropriate follow-up investigations. © 2011 The Authors.

Accumulating evidence shows that high sodium chloride intake increases urinary calcium excretion and may be a risk factor for osteoporosis. However, the effect of oral sodium chloride intake on bone mineral density (BMD) and risk of osteoporosis has been inadequately researched. The aim of the present study was to determine whether urinary sodium excretion (reflecting oral sodium chloride intake) associates with BMD and prevalence of osteoporosis in postmenopausal women. This cross-sectional study involved a nationally representative sample consisting of 2,779 postmenopausal women who participated in the Korea National Health and Nutritional Examination Surveys in 2008-2011. The association of urinary sodium/creatinine ratio with BMD and other osteoporosis risk factors was assessed. In addition, the prevalence of osteoporosis was assessed in four groups with different urinary sodium/creatinine ratios. Participants with osteoporosis had significantly higher urinary sodium/creatinine ratios than the participants without osteoporosis. After adjusting for multiple confounding factors, urinary sodium/creatinine ratio correlated inversely with lumbar spine BMD (P = 0.001). Similarly, when participants were divided into quartile groups according to urinary sodium/creatinine ratio, the average BMD dropped as the urinary sodium/creatinine ratio increased. Multiple logistic regression analysis revealed that compared to quartile 1, quartile 4 had a significantly increased prevalence of lumbar spine osteoporosis (odds ratios 1.346, P for trend = 0.044). High urinary sodium excretion was significantly associated with low BMD and high prevalence of osteoporosis in lumbar spine. These results suggest that high sodium chloride intake decreases lumbar spine BMD and increases the risk of osteoporosis in postmenopausal women.

Botswana has the second-highest human immunodeficiency virus (HIV) infection rate in the world, with one in three adults infected. However, there is significant geographic variation at the district level and HIV prevalence is heterogeneous with the highest prevalence recorded in Selebi-Phikwe and North East. There is a lack of age-and location-adjusted prevalence maps that could be used for targeting HIV educational programs and efficient allocation of resources to higher risk groups. We used a nationally representative household survey to investigate and explain district level inequalities in HIV rates. A Bayesian geoadditive mixed model based on Markov Chain Monte Carlo techniques was applied to map the geographic distribution of HIV prevalence in the 26 districts, accounting simultaneously for individual, household, and area factors using the 2008 Botswana HIV Impact Survey. Overall, HIV prevalence was 17.6%, which was higher among females (20.4%) than males (14.3%). HIV prevalence was higher in cities and towns (20.3%) than in urban villages and rural areas (16.6% and 16.9%, respectively). We also observed an inverse U-shape association between age and prevalence of HIV, which had a different pattern in males and females. HIV prevalence was lowest among those aged 24 years or less and HIV affected over a third of those aged 25-35 years, before reaching a peak among the 36-49-year age group, after which the rate of HIV infection decreased by more than half among those aged 50 years and over. In a multivariate analysis, there was a statistically significant higher likelihood of HIV among females compared with males, and in clerical workers compared with professionals. The district-specific net spatial effects of HIV indicated a significantly higher HIV rate of 66% (posterior odds ratio of 1.66) in the northeast districts (Selebi-Phikwe, Sowa, and Francistown) and a reduced rate of 27% (posterior odds ratio of 0.73) in Kgalagadi North and Kweneng West districts

Background ODD is considered to be a disorder of childhood, yet evidence suggests that prevalence rates of the disorder are stable into late adolescence and trajectories of symptoms persist into young adulthood. Functional outcomes associated with ODD through childhood and adolescence include conflict within families, poor peer relationships, peer rejection and academic difficulties. Little examination of functional outcomes in adulthood associated with ODD has been undertaken. Method Data for the present analyses come from a clinic referred sample of 177 boys aged 7 to 12 followed up annually to age 18 and again at age 24. Annual parental report of psychopathology through adolescence was used to predict self-reported functional outcomes at 24. Results Controlling for parent reported symptoms of ADHD, CD, depression and anxiety, ODD symptoms from childhood through adolescence predicted poorer age 24 functioning with peers, poorer romantic relationships, a poorer paternal relationship, and having nobody who would provide a recommendation for a job. CD symptoms predicted workplace problems, poor maternal relationship, lower academic attainment and violent injuries. Only parent reported ODD symptoms and child reported CD symptoms predicted a composite of poor adult outcomes. Conclusion ODD is a disorder that significantly interferes with functioning, particularly in social or interpersonal relationships. The persistence of impairment associated with ODD into young adulthood calls for a reconsideration of ODD as a disorder limited to childhood. PMID:24117754

Objective: To assess the prevalence and determinants of satisfaction among diabetes mellitus patients about the doctors in a major public diabetes clinic in Lahore. Methodology: This cross-sectional study was conducted among 1,128 adult patients of diabetes mellitus. The questionnaire was based on the Urdu translation of an internationally validated tool: Patient Satisfaction Questionnaire 3. Data were analyzed using SPSS Version 22.0. The results are shown by Adjusted Odds Ratio (AOR), 95% Confidence Interval (CI). Results: The overall prevalence of patient satisfaction with the doctors was 86%. Patient's gender male (AOR=.41; 95%CI=.26-.63) and higher education (AOR=.33; 95%CI=.17-.63) were found to be associated with lower likelihood of satisfaction. Patient's perception of low technical expertise, poor interpersonal aspects and inappropriate time provision was associated with lower odds of patient satisfaction. Conclusion: Despite the prevalence of patient satisfaction was found to be high, the patients' perception of doctor's skills determines their satisfaction. Patient satisfaction studies should be conducted on regular basis to assess and improve the nature of patient experiences in public out-patient departments. (author)

To analyze 5-year prevalence trends in Chlamydia trachomatis infections among high-risk young men and women aged 16 to 24 years entering the National Job Training Program, where universal screening is required. Entrance exams conducted in over 100 National Job Training Program centers from 2003 to 2007 were considered. Women provided cervical specimens tested using either a DNA hybridization probe (PACE 2, Gen-Probe, San Diego, CA) or a strand displacement amplification test (SDA, BD ProbeTec ET, Becton-Dickinson, Sparks, MD). In the absence of a pelvic exam, urine specimens were tested using SDA. PACE 2 testing was performed predominately from 2002 to 2005; from 2005 to 2007, SDA was used. All male testing was conducted using SDA on urine specimens. Chlamydia prevalence trends were assessed for women and men, using logistic regression models. Adjusted odds ratios (AOR), 95% confidence intervals (CI), and P-values were calculated. Approximately 15,000 women and 30,000 men were screened annually for chlamydia. Among both sexes, adjusted prevalence declined significantly from 2003 to 2007. In 2003, crude prevalence among women was 9.9%; in 2007, prevalence was 13.7%. However, after controlling for covariates, including increasingly sensitive tests, the model indicated a significant declining prevalence trend (AOR: 0.95, CI: 0.93-0.97, 4.6% decrease in odds per year). Among men, crude prevalence in 2003 was 8.4%; in 2007, prevalence was 8.3%; after controlling for possible confounding, a significant decline in prevalence was also detected (AOR: 0.98, CI: 0.96-0.99, 1.9% decrease in odds per year). In a relatively stable, high-risk population of young women and men, adjusted chlamydia prevalence declined from 2003 to 2007. Test technology plays a critical role in interpreting rates and should be considered whenever chlamydia rates are examined.

Quasiparticle features and level statistics of odd-odd nucleus

The energy levels of the odd-odd nucleus 84 Y are calculated by using the axially symmetric rotor plus quasiparticles model. The two standard statistical tests of Random-Matrix Theory such as the distribution function p(s) of the nearest-neighbor level spacings (NNS) and the spectral rigidity Δ 3 are used to explore the statistical properties of the energy levels. By analyzing the properties of p(s) and Δ 3 under various conditions, the authors find that the quasiparticle features mainly affect the statistical properties of the odd-odd nucleus 84 Y through the recoil term and the Coriolis force in this theoretical mode, and that the chaotic degree of the energy levels decreases with the decreasing of the Fermi energy and the energy-gap parameters. The effect of the recoil term is small while the Coriolis force plays a major role in the spectral structure of 84 Y

Purpose: To investigate the most practical option available when statistically analysing small sample size studies. Method: The log odds ratio was applied to a study which took a retrospective approach and involved 50 patients who had undergone a ventilation and perfusion scan in the period between 01 January 2002 and 31 December 2002. Radiology reports and the patients' medical records were obtained, so that the clinical indications for the examination and the patients' medical history could be transferred onto the report form. Four radiographers who are routinely rotated into the Nuclear Medicine Department independently reported the same 50 ventilations and perfusion scans under identical conditions to the reporting radiologist. Results: Taking the radiologist reports as the gold standard the radiographers had an accuracy rate of 78%. The radiographers recorded an average sensitivity value of 94% and specificity value of 63%, with an A z reading of 0.71. Conclusion: As the sample size was too small for a receiver operating characteristic (ROC) curve to be drawn, the log odds ratio provided a value, which represents an area under the receiver operating characteristic (ROC) curve, which in turn ensured the results were statistically reliable. The log odds ratio enables researchers to carry out small-scale research without harbouring the data collected by unreliable analysis

Previous studies have suggested that cocoa products, which are rich sources of flavonoids, may lower blood pressure, serum cholesterol, fasting blood glucose and improve endothelial function. However, it is unclear whether consumption of cocoa products including chocolate influences the risk of metabolic syndrome (MetS). In a cross-sectional design, we sought to examine the association between chocolate consumption and the prevalence of MetS. We studied 4098 participants from the National Heart, Lung, and Blood Institute (NHLBI) Family Heart Study aged 25-93 years. Chocolate consumption was assessed using a semi-quantitative food-frequency questionnaire. MetS was defined using the NCEP III criteria. Generalized estimating equations were used to estimate prevalence odds ratios of MetS according to frequency of chocolate intake. Of the 4098 participants (mean age 51.7 y) included in the analyses, 2206 (53.8%) were female. The prevalence of metabolic syndrome in our population was 30.2%. Compared with those who did not consume any chocolate, multivariate adjusted odds ratios (95% CI) for MetS were 1.26 (0.94, 1.69), 1.15 (0.85, 1.55), and 0.99 (0.66, 1.51) among women who reported chocolate consumption of 1-3 times/ month, 1-4 times/week, and 5+ times/week, respectively. Corresponding values for men were: 1.13 (0.82, 1.57), 1.02 (0.74, 1.39), and 1.21 (0.79, 1.85). These data do not support an association between chocolate intake and the prevalence of MetS in US adult men and women.

Because research is needed to identify the conditions that facilitate or impede the prevalence of perceived workplace discrimination, the authors examined the effects of demographics and demographic similarity on the prevalence of sex- and race/ethnicity-based perceived workplace discrimination. Results from a national survey of 763 full-time, United States employees show perceived sex-based discrimination at work was more prevalent among female than male employees, and perceived race-based discrimination at work was more prevalent among Black and Hispanic than White employees. Additionally, perceived racial/ethnic discrimination was less prevalent among those with same-race/ethnicity supervisors. The effect of employee-coworker sex similarity on perceived sex discrimination was significant only for women, and the effects of supervisor-subordinate racial similarity on the prevalence of perceived racial discrimination varied between Black and White respondents, depending on employee-residential-community racial similarity.

Full Text Available Objectives: The objective of this study is to determine the prevalence and sociodemographic correlates for mental illness among inmates at Mukobeko Maximum Security Prison, Zambia. Materials and Methods: A cross sectional study was conducted to assess psychiatric disturbance using a Self-Reported Questionnaire (SRQ20. A cut off point of 7/8 was used. The Chi-square test and Fishers′ exact test were used to determine associations at the 5% significance level, and magnitude of association was estimated using the odds ratio and its 95% confidence interval. Results: Of the 394 inmates in prison, 29.2% had a current mental illness. Gender status was significantly associated with mental illness. Male participants were 35% (odds ratio = 0.65, 95% confidence interval [0.51, 0.82] less likely to have mental illness compared to female participants. Conclusions: The prevalence of mental illness is high in Mukobeko Maximum Security Prison in Zambia. Gender-specific interventions should be designed to reduce the level of mental illness in this prison.

To investigate the prevalence, predictors, and management of anaemia in pregnancy. A multi centre study across 11 maternity units in the UK. Data were collected over a two week study period in 2008 on maternal history, haemoglobin (Hb) and ferritin concentrations, iron therapy during pregnancy and in the postpartum period. Logistic regression models were used to explore factors associated with anaemia during pregnancy. Main outcomes included anaemia, defined as Hbanaemia by 32 weeks gestation included young maternal age (odds ratio 1.96, 95% CI 1.38-2.79), non-white ethnic origin (odds ratios varied 1.37-2.89 depending on ethnic origin) and increasing parity (odds ratio 1.24, 95% CI 1.08-1.41). Of women who had postnatal Hb levels checked, 30% (309/1031) were anaemic and, depending on centre, 16% to 86% of these received iron therapy. Anaemia was reported in nearly one in four women in the antenatal period, and nearly one in three of the women who had a postpartum Hb checked. Despite national guidelines, there was considerable variation in administration of iron including low utilisation of parenteral iron therapy. Future research needs to focus on the consequences of iron deficiency anaemia for maternal and infant health outcomes and effectiveness of implementation strategies to reduce anaemia.

Credible inferences regarding the burden of vertebral fractures (VFs) cannot be made without a globally accepted quantitative definition of 'fracture'. Currently, differences in anterior, middle, or posterior vertebral heights (VHs) within a vertebra, or between adjacent vertebrae, are used to define 'fracture'. However, VH differences are essential for the construction of thoracolumbar curves, evolutionary adaptations that provide stability in bipedal stance and gait. As there is no reference standard to distinguish anatomical variation from fracture, approaches to defining a VF use a reference range of VH ratios derived in premenopausal women or derived by trimming, a method that iteratively removes the tails of a distribution of VH ratios to produce a normal distribution. From this, reference ranges of VH ratio means and standard deviations (SDs) are obtained and a nominal deviation of 15% or more, or 3 SD or more is regarded as a 'fracture'. We measured VHs by quantitative vertebral morphometry (QVM) and bone mineral density (BMD) by dual energy X-ray absorptiometry in 697 Lebanese women (age 20-89 years) to compare the prevalence of VF ascertained by published methods and a new method that uses the premenopausal range (without trimming) and requires two VH abnormalities. VF prevalence using published methods reached 60% to 70% in pre- and post-menopausal women, and in women with normal or high BMD because VH ratios were not normally distributed and cut-offs used to define VF fracture fell within the observed distribution of the data. The new method resulted in a VF prevalence of 3.3% in younger and 14% in older women, 7% (high), 10% (middle), and 20% (low) BMD tertiles consistent with the notion that the method detected VF due to bone fragility. We suggest that using a fixed trimming method to define reference range and cut-offs or applying fixed cut-offs to identify VFs in populations, where these ratios are not normally distributed, may result in the capture

A technique for modeling quasiparticle excitation energies and rotational parameters in odd-odd deformed nuclei has been applied to actinide species where new experimental data have been obtained by use of neutron-capture gamma-ray spectroscopy. The input parameters required for the calculation were derived from empirical data on single-particle excitations in neighboring odd-mass nuclei. Calculated configuration-specific values for the Gallagher-Moszkowski splittings were used. Calculated and experimental level structures for 238 Np, 244 Am, and 250 Bk are compared, as well as those for several nuclei in the rare-earth region. The agreement for the actinide species is excellent, with bandhead energies deviating 22 keV and rotational parameters 5%, on the average. Corresponding average deviations for five rare-earth nuclei are 47 keV and 7%. Several applications of this modeling technique are discussed. 18 refs., 5 figs., 4 tabs

Sleep disordered breathing (SDB) is a highly prevalent condition in high-income countries, with major consequences for cardiopulmonary health, public safety, healthcare utilization, and mortality. However, its prevalence and effect in low- and middle-income countries are less well known. We sought to determine the prevalence, risk factors, and comorbidities of SDB symptoms in four resource-limited settings. Cross-sectional analysis of the CRONICAS Cohort, a population-based age- and sex-stratified sample. Four resource-limited settings in Peru varying in altitude, urbanization, and air pollution. There were 2,682 adults aged 35 to 92 y. Self-reported SDB symptoms (habitual snoring, observed apneas, Epworth Sleepiness Scale), sociodemographics, medical history, anthropometrics, spirometry, blood biomarkers were reported. We found a high prevalence of habitual snoring (30.2%, 95% confidence interval [CI] 28.5-32.0%), observed apneas (20.9%, 95% CI 19.4-22.5%) and excessive daytime sleepiness (18.6%, 95% CI 17.1-20.1%). SDB symptoms varied across sites; prevalence and adjusted odds for habitual snoring were greatest at sea level, whereas those for observed apneas were greatest at high altitude. In multivariable analysis, habitual snoring was associated with older age, male sex, body mass index (BMI), and higher socioeconomic status; observed apneas were associated with BMI; and excessive daytime sleepiness was associated with older age, female sex, and medium socioeconomic status. Adjusted odds of cardiovascular disease, depression, and hypertension and total chronic disease burden increased progressively with the number of SDB symptoms. A threefold increase in the odds of having an additional chronic comorbid disease (adjusted odds ratio 3.57, 95% CI 2.18-5.84) was observed in those with all three versus no SDB symptoms. Sleep disordered breathing symptoms were highly prevalent, varied widely across four resource-limited settings in Peru, and exhibited strong

We investigated the prevalence and correlates of prefrailty/frailty, determined on the basis of the Fried criteria, in Chinese patients with and those without human immunodeficiency virus (HIV) infection. HIV-infected patients were more likely to be frail or prefrail than controls, and this association remained significant after adjustment for potential confounders (odds ratio, 3.79). After additional adjustment for neurocognitive impairment and depressive and insomnia symptoms, this association remained significant but attenuated (odds ratio, 2.16). In the HIV-infected group, these 3 variables were independently associated with prefrailty/frailty. These findings suggest that neurocognitive impairment and depressive and/or insomnia symptoms may account for a higher prevalence of prefrailty/frailty in HIV-infected patients but require further longitudinal investigation. © The Author 2017.

Rotational spectra of odd-odd Rh and Ag isotopes are investigated with the primary motivation to search for the spontaneous chiral symmetry breaking phenomenon in these nuclei. The experimental results obtained on the degenerate dipole bands of some of these isotopes using a large array of gamma detectors are discussed and studied using the triaxial projected shell (TPSM) approach. It is shown that, first of all, to reproduce the odd-even staggering of the known yrast bands of these nuclei, large triaxial deformation is needed. This large triaxial deformation also gives rise to doublet band structures in many of these studied nuclei. The observed doublet bands in these isotopes are shown to be reproduced reasonably well by the TPSM calculations. Further, the TPSM calculations for neutron-rich nuclei indicate that the ideal manifestation of the chirality can be realised in {sup 106}Rh and {sup 112}Ag, where the doublet bands have similar electromagnetic properties along with small differences in excitation energies.

To evaluate trends in atrial fibrillation (AF) prevalence in acute ischemic stroke (AIS) and TIA in the United States. We used the Nationwide Inpatient Sample to retrospectively compute weighted prevalence of AF in AIS (n = 4,355,140) and TIA (n = 1,816,459) patients admitted to US hospitals from 2004 to 2013. Multivariate-adjusted models were used to evaluate the association of AF with clinical factors, mortality, length of stay, and cost. From 2004 to 2013, AF prevalence increased by 22% in AIS (20%-24%) and by 38% in TIA (12%-17%). AF prevalence varied by age (AIS: 6% in 50-59 vs 37% in ≥80 years; TIA: 4% in 50-59 vs 24% in ≥80 years), sex (AIS: male 19% vs female 25%; TIA: male 15% vs female 14%), race (AIS: white 26% vs black 12%), and region (AIS: Northeast 25% vs South 20%). Advancing age, female sex, white race, high income, and large hospital size were associated with increased odds of AF in AIS. AF in AIS was a risk factor for in-hospital death (odds ratio 1.93, 95% confidence interval 1.89-1.98) but mortality in AIS with AF decreased from 11.6% to 8.3% (p TIA has continued to increase. Disparity in AF prevalence in AIS and TIA exists by patient and hospital factors. AF is associated with increased mortality in AIS. Innovative AIS preventive strategies are needed in patients with AF, especially in the elderly. © 2016 American Academy of Neurology.

Conflicting Coupling of Unpaired Nucleons and the Structure of Collective Bands in Odd-Odd Nuclei

The conflicting coupling of unpaired nucleons in odd-odd nuclei is discussed. A very simple explanation is suggested for the damping of the energy spacing of the lowest levels in the rotational bands in odd-odd nuclei with the 'conflicting' coupling of an odd proton and an odd neutron comparative to those of the bands based on the state of a strongly coupled particle in the neighboring odd nucleus entering the 'conflicting' configuration.

Enhanced T-odd, P-odd electromagnetic moments in reflection asymmetric nuclei

Spevak, V.; Auerbach, N.; Flambaum, V.V.

1997-01-01

Collective P- and T-odd moments produced by parity and time invariance violating forces in reflection asymmetric nuclei are considered. The enhanced collective Schiff, electric dipole, and octupole moments appear due to the mixing of rotational levels of opposite parity. These moments can exceed single-particle moments by more than 2 orders of magnitude. The enhancement is due to the collective nature of the intrinsic moments and the small energy separation between members of parity doublets. In turn these nuclear moments induce enhanced T- and P-odd effects in atoms and molecules. A simple estimate is given and a detailed theoretical treatment of the collective T-, P-odd electric moments in reflection asymmetric, odd-mass nuclei is presented. In the present work we improve on the simple liquid drop model by evaluating the Strutinsky shell correction and include corrections due to pairing. Calculations are performed for octupole deformed long-lived odd-mass isotopes of Rn, Fr, Ra, Ac, and Pa and the corresponding atoms. Experiments with such atoms may improve substantially the limits on time reversal violation. copyright 1997 The American Physical Society

Full Text Available Objective: To determine the prevalence and determinants of chronic periodontitis in HIV positive patients. Methods: A total of 120 HIV positive patients attending the dedicated HIV outpatient clinic of the Lagos University Teaching Hospital, Nigeria were recruited for the study. Their periodontal status was assessed using the community periodontal index of treatment needs. Their CD4+ cell count was determined using the flow-cytometer method. The risk factors for periodontitis including age, gender, education, smoking, CD4+ cell counts, bleeding on probing (BOP were determined. Results: Prevalence of periodontitis was high (63.3% in the HIV positive patients. In a bivariate analysis, significant associations were observed between severity of periodontitis and age ≥35 years (P=0.021, male gender (P=0.005, smoking (P=0.040 and ≥3 community periodontal index of treatment needs sextants exhibiting BOP (P=0.004. In a binary logistic regression, independent predictors of periodontitis were ≥3 sextants exhibiting BOP (odds ratio 1.738, 95% CI 1.339 to 2.256, P=0.000 and age ≥35 years (odds ratio 1.057, 95% CI 1.005 to 1.111, P=0.030. The CD4+ cell counts were not associated with periodontitis in the HIV positive patients (P=0.988. Conclusions: A high prevalence of periodontitis was found among the HIV positive Nigerian patients in this study. Older age ≥35 years and BOP were the determinants of periodontitis. There is therefore a need for close periodontal monitoring of HIV positive Nigerian patients with emphasis on preventive, professional oral prophylaxis.

Potential misinterpretation of treatment effects due to use of odds ratios and logistic regression in randomized controlled trials.

Directory of Open Access Journals (Sweden)

Mirjam J Knol

Full Text Available BACKGROUND: In randomized controlled trials (RCTs, the odds ratio (OR can substantially overestimate the risk ratio (RR if the incidence of the outcome is over 10%. This study determined the frequency of use of ORs, the frequency of overestimation of the OR as compared with its accompanying RR in published RCTs, and we assessed how often regression models that calculate RRs were used. METHODS: We included 288 RCTs published in 2008 in five major general medical journals (Annals of Internal Medicine, British Medical Journal, Journal of the American Medical Association, Lancet, New England Journal of Medicine. If an OR was reported, we calculated the corresponding RR, and we calculated the percentage of overestimation by using the formula . RESULTS: Of 193 RCTs with a dichotomous primary outcome, 24 (12.4% presented a crude and/or adjusted OR for the primary outcome. In five RCTs (2.6%, the OR differed more than 100% from its accompanying RR on the log scale. Forty-one of all included RCTs (n = 288; 14.2% presented ORs for other outcomes, or for subgroup analyses. Nineteen of these RCTs (6.6% had at least one OR that deviated more than 100% from its accompanying RR on the log scale. Of 53 RCTs that adjusted for baseline variables, 15 used logistic regression. Alternative methods to estimate RRs were only used in four RCTs. CONCLUSION: ORs and logistic regression are often used in RCTs and in many articles the OR did not approximate the RR. Although the authors did not explicitly misinterpret these ORs as RRs, misinterpretation by readers can seriously affect treatment decisions and policy making.

Full Text Available Metabolic syndrome (MetS is a growing problem in the United Arab Emirates (UAE. Moreover, the prevalence of overweight and obesity is rapidly increasing in the UAE especially among young females. However, few studies have evaluated the prevalence of MetS among young female adults in the UAE. This study determined the prevalence of MetS in Emirati females aged 17-25 years and its relation to overweight and obesity.In total, 555 Emirati female college students were enrolled in a cross-sectional study, conducted during 2013-2014 at United Arab Emirates University in Al Ain, UAE. Anthropometric measurements, blood pressure and biochemical measurements were collected. MetS was defined according to the harmonised International Diabetes Federation criteria.Of the 555 participants enrolled, 23.1% were overweight and 10.4% were classified as obese. The overall prevalence of MetS was 6.8%. MetS prevalence was highest among obese participants (34.5%, as compared with normal-weight (1.7% and overweight (10.1% participants. MetS was significantly associated with overweight (adjusted odds ratio [aOR] = 3.8, 95% confidence interval [CI]; 1.15-12.52 and obesity (aOR = 11.2, 95% CI; 3.1-40.9, as compared with normal-weight. Waist-hip ratio ≥ 0.8 (aOR = 3.04, 95% CI; 1.10-8.44 was significantly associated with MetS, as compared with waist-hip ratio <0.8. The odds of MetS were 22 fold higher in participants with glycated haemoglobin (HbA1c ≥ 6.5% (aOR = 22.5, 95% CI; 6.37-79.42 compared to HbA1c <6.5%. This difference was 9 fold higher when HbA1c between 5.6%-6.4% was compared to HbA1c <5.6% (aOR = 8.9, 95% CI; 3.4-23.5.The prevalence of MetS among obese Emirati female students was significantly higher than overweight and normal weight students. The high prevalence of MetS highlights the importance of regular screening and intervention programmes targeting weight reduction.

Smoking, the leading cause of disease and death in the United States, has been linked to a number of health conditions including cancer and cardiovascular disease. While people with a disability have been shown to be more likely to report smoking, little is known about the prevalence of smoking by type of disability, particularly for adults younger than 50 years of age. We used data from the 2009-2011 National Health Interview Survey to estimate the prevalence of smoking by type of disability and to examine the association of functional disability type and smoking among adults aged 18-49 years. Adults with a disability were more likely than adults without a disability to be current smokers (38.8% vs. 20.7%, p<0.001). Among adults with disabilities, the prevalence of smoking ranged from 32.4% (self-care difficulty) to 43.8% (cognitive limitation). When controlling for sociodemographic characteristics, having a disability was associated with statistically significantly higher odds of current smoking (adjusted odds ratio = 1.57, 95% confidence interval 1.40, 1.77). The prevalence of current smoking for adults was higher for every functional disability type than for adults without a disability. By understanding the association between smoking and disability type among adults younger than 50 years of age, resources for cessation services can be better targeted during the ages when increased time for health improvement can occur.

The high-spin states of odd-odd nucleus 170 Ta were populated via the 155 Gd( 19 F, 4n) 170 Ta reaction with beam energy of 97 MeV provided by the HI-13 tandem accelerator of China Institute of Atomic Energy. Three rotational bands have been pushed to higher spin states and the signature inversion point of the semidecoupled band based on the πh 9/2 1/2 - [541] direct x νi 13/2 configuration has been observed to be 19.5 ℎ. The systematic features of the signature inversion in semidecoupled bands in odd-odd rare earth nuclei were summarized. The systematic differences of signature inversion, especially the difference in the energy splitting between the yrast hands and the semidecoupled hands in odd-odd rare earth nuclei are pointed out and discussed for the first time. It seems that p-n interaction between the odd proton and odd neutron in the odd-odd nuclei plays an important role

Infections caused by Chlamydia trachomatis (Ct) and human papillomavirus (HPV) are the two main sexually transmitted infections; however, epidemiological data on Ct prevalence and Ct/HPV co-infection in Italy are scant. This study aimed at estimating the prevalence of Ct infection and Ct/HPV co-infection in young HPV-unvaccinated females with normal cytology, and placed particular attention on the possible association between Ct-DNA positivity and different HPV infecting genotypes. Five hundred 66 healthy females aged 16-26 years without cervical lesions, previously assessed for HPV infection (HPV-DNA prevalence: 18.2%), were tested for Ct-DNA. The overall prevalence of Ct was 5.8% (95% CI: 4.2-8.1), while Ct/HPV co-infection was recorded in 2.7% (95% CI: 1.6-4.3) of subjects. Compared with HPV-DNA-negative females, HPV-DNA positive subjects had significantly (P < 0.001) higher odds of being infected with Ct (odds ratio of 4.20, 95% CI: 2.01-8.71). Both Ct and Ct/HPV infections were much more prevalent in under 18-year-olds than in older women. Subjects positive for single high-risk HPV genotypes and various multiple HPV infections had higher odds of being Ct-DNA positive. Our findings confirm that HPV and Ct infections are very common among asymptomatic young Italian females. This underlines the urgent need for nationwide Ct screening programs and reinforcement of sexual health education, which would be the most important public health strategies, since no Ct vaccines are currently available.

Delusional jealousy (DJ) has been described in patients with Parkinson's disease (PD) on dopaminergic therapy, but a role for dopaminergic therapy in DJ has not been established. The current cross-sectional study on DJ investigated its association with dopaminergic therapies compared with their associations with hallucinations and its prevalence in PD patients. Eight hundred five consecutive patients with PD were enrolled between January 2009 and June 2010. DJ was identified in 20 patients (2.48%) and hallucinations in 193 patients (23.98%). In the multivariate logistic regression analyses, dopamine agonists were significantly associated with DJ (odds ratio, 18.1; 95% CI, 3.0-infinity; P = .0002) but not with hallucinations (odds ratio, 0.73; 95% CI, 0.49-1.10; P = .133). These findings suggest that dopamine agonist treatment represents a risk factor for DJ in PD independent of the presence of a dementing disorder, and the presence of this additional nonmotor side effect should be investigated in this clinical population.

2017-06-01

The alpha-cluster probability that represents the preformation of alpha particle in alpha-decay nuclei was determined for high-intensity alpha-decay mode odd-A and odd-odd heavy nuclei, 82 CSR) and the hypothesised cluster-formation model (CFM) as in our previous work. Our previous successful determination of phenomenological values of alpha-cluster preformation factors for even-even nuclei motivated us to expand the work to cover other types of nuclei. The formation energy of interior alpha cluster needed to be derived for the different nuclear systems with considering the unpaired-nucleon effect. The results showed the phenomenological value of alpha preformation probability and reflected the unpaired nucleon effect and the magic and sub-magic effects in nuclei. These results and their analyses presented are very useful for future work concerning the calculation of the alpha decay constants and the progress of its theory.

We consider a bottom-up holographic model of QCD at finite temperature T and magnetic field B, and study dependence of thermodynamics and CP-odd transport on these variables. As the magnetic field couples to the flavor sector only, one should take the Veneziano limit where the number of flavors and colors are large while their ratio is kept fixed. We investigate the corresponding holographic background in the approximation where the ratio of flavors to colors is finite but small. We demonstrate that B-dependence of the entropy of QCD is in qualitative agreement with the recent lattice studies. Finally we study the CP-odd transport properties of this system. In particular, we determine the Chern-Simons decay rate at finite B and T, that is an important ingredient in the Chiral Magnetic Effect.

Observational studies suggest association between low concentrations of omega-3 family fatty acids and greater risk for post-partum depression (PPD). The objective was to investigate the effect of unbalanced dietary intake of omega-6/omega-3 ratio >9:1 in the prevalence for PPD. The study comprises a prospective cohort with four waves of follow-up during pregnancy and one following delivery. PPD was evaluated according to the Edinburgh Post-partum Depression Scale (PPD ≥ 11) in 106 puerperae between 2005 and 2007, in Rio de Janeiro, Brazil. Independent variables included socio-demographic, obstetric, pre-pregnancy body mass index (BMI) and dietary intake data, which were obtained by means of a food frequency questionnaire in the first trimester of pregnancy. Statistical analysis involved calculation of PPD prevalence and multivariate Poisson regression with robust variance. PPD prevalence amounted to 26.4% [n = 28; confidence interval (CI) 95%: 18.0-34.8], and higher prevalences of PPD were observed in women who consumed an omega-6/omega-3 ratio >9:1 (60.0%) and in those with pre-pregnancy BMI <18.5 kg/m(2) (66.7%). These variables held as factors associated to PPD in the multivariate model, elevating the chances of occurrence of the outcome in 2.50 (CI 95%: 1.21-5.14) and 4.01 times (CI 95%: 1.96-8.20), respectively. Analyses were adjusted for age, schooling, pre-pregnancy BMI, lipids consumption and time elapsed since delivery. It verified an association between omega-6/omega-3 ratio above 9:1, the levels recommended by the Institute of Medicine, and the prevalence of PPD. These results add to the evidence regarding the importance of omega-6 and omega-3 fatty acids in the regulation of mental health mechanisms. © 2010 Blackwell Publishing Ltd.

Social phobia may seriously impair the functioning of affected individuals. It is frequently associated with other mental disorders. To estimate the co-occurrence of social phobia with major depressive disorder (MDD) and to analyze their interaction. Subjects were 18,980 individuals, aged 15 years or older, representative of the general population of the United Kingdom, Germany, Italy, Spain and Portugal, who were interviewed by telephone. DSM-IV diagnoses were made with the Sleep-EVAL system. The point prevalence for social phobia was 4.4% (95% confidence interval: 4.1-4.7%) of the sample. It was higher in women (odds ratio: 1.6) and decreased with age. MDDs were found in 19.5% of participants with social phobia. Co-occurrence of another anxiety disorder was high and increased when a MDD was present (65.2%). The odds of developing a major depressive episode 2 years after the appearance of the social phobia was of 5.74. Social phobia is highly prevalent in the general population. It increases the risk of developing a MDD and has a high comorbidity with other mental disorders. Social phobia is often present in the course of depression, more obviously during remission period of MDD. Physicians must explore and treat more systematically this frequent pathology.

Full Text Available BACKGROUND Detecting the evidence of gestational diabetes mellitus is a major challenge as the condition is associated with diverse range of adverse maternal and neonatal outcome. Also, women detected with gestational diabetes mellitus have an increased incidence of diabetes especially type 2 diabetes mellitus in the later life and future development of obesity and diabetes in the offspring. Studies conducted in different populations and with different methodologies consistently reported an increase in GDM prevalence. A true increase in the prevalence of GDM aside from its adverse consequences for the infant and newborn period might reflect or contribute to the ongoing pattern of increasing diabetes and obesity. 1&2 The aim of the study is to1. Validate the Diabetes in Pregnancy Study Group of India (DIPSI recommended 75 grams glucose test for the diagnosis of gestational mellitus by comparing with the WHO criteria and ADA criteria. 2. Study the prevalence of gestational diabetes in antenatal population attending Government Kilpauk Medical College Hospital. 3. Study the prevalence of following risk factors in GDM. MATERIALS AND METHODS This prospective study was conducted in 350 antenatal women of 24-28 weeks gestational age who attended antenatal clinic in Government Kilpauk Medical College Hospital, Chennai. This study was done after getting clearance from ethical committee of Government Kilpauk Medical College Hospital. RESULTS Incidence of GDM was 4%. DIPSI criteria had a diagnostic accuracy, sensitivity and specificity of 98.86%, 100% and 98.82%. WHO criteria had a diagnostic accuracy, sensitivity and specificity of 99.43%, 100% and 99.41%.

Full Text Available BACKGROUND AND AIMS: Metabolic syndrome (MS is prevalent in recent years but few data is reported in the rural areas in China. The aim of this study was to examine MS prevalence and its risk factors among women in rural China. METHODS AND RESULTS: The Nantong Metabolic Syndrome Study (NMSS, a population based cross-sectional study, was conducted during 2007-2008 in Nantong, China. In person interviews, blood glucose and lipid measurements were completed for 13,505 female participants aged 18-74 years. The International Diabetes Federation (IDF, the US Third Report of the National Cholesterol Education Program, the Adult Treatment Panel (ATPIII and modified ATPIII for Asian population has determined three criteria of MS. These criteria for MS were used and compared in this study. The prevalence of MS was 22.0%, 16.9% and 23.3% according to IDF, ATPIII and ATPIII-modified criteria, respectively. Levels of agreement of these criteria for MS were above 0.75. We found that vigorous-intensity of occupational physical activity was associated with a low prevalence of MS with OR of 0.76 (95% confidence interval (CI: 0.63-0.91. Rice wine drinkers (alcohol >12.8 g/day had about 34% low risks of developing MS with OR of 0.66 (95% CI: 0.48-0.91, compared with non-drinkers. Odds ratio of MS was 1.81 (95% CI: 1.15-2.84 in women who smoked more than 20 pack-years, compared to non-smokers. Odds ratio of MS was 1.56 (95% CI: 1.25-1.95 in women who had familial history of diseases, including hypertension, diabetes and stroke, compared to women without familial history of those diseases. CONCLUSION: MS is highly prevalent among women in rural China. Both physical activity and rice wine consumption play a protective role, while family history and smoking are risk factors in MS development. Educational programs should be established for promoting healthy lifestyles and appropriate interventions in rural China.

Full Text Available Cancers often involve the synergistic effects of gene–gene interactions, but identifying these interactions remains challenging. Here, we present an odds ratio-based genetic algorithm (OR-GA that is able to solve the problems associated with the simultaneous analysis of multiple independent single nucleotide polymorphisms (SNPs that are associated with oral cancer. The SNP interactions between four SNPs—namely rs1799782, rs2040639, rs861539, rs2075685, and belonging to four genes (XRCC1, XRCC2, XRCC3, and XRCC4—were tested in this study, respectively. The GA decomposes the SNPs sets into different SNP combinations with their corresponding genotypes (called SNP barcodes. The GA can effectively identify a specific SNP barcode that has an optimized fitness value and uses this to calculate the difference between the case and control groups. The SNP barcodes with a low fitness value are naturally removed from the population. Using two to four SNPs, the best SNP barcodes with maximum differences in occurrence between the case and control groups were generated by GA algorithm. Subsequently, the OR provides a quantitative measure of the multiple SNP synergies between the oral cancer and control groups by calculating the risk related to the best SNP barcodes and others. When these were compared to their corresponding non-SNP barcodes, the estimated ORs for oral cancer were found to be great than 1 [approx. 1.72–2.23; confidence intervals (CIs: 0.94–5.30, p < 0.03–0.07] for various specific SNP barcodes with two to four SNPs. In conclusion, the proposed OR-GA method successfully generates SNP barcodes, which allow oral cancer risk to be evaluated and in the process the OR-GA method identifies possible SNP–SNP interactions.

Full Text Available We discuss the non-adiabatic quasiparticle approach for calculating the rotational spectra and decay width of odd-odd proton emitters. The Coriolis effects are incorporated in both the parent and daughter wave functions. Results for the two probable ground states (1+ and 2+ of the proton emitter 130Eu are discussed. With our calculations, we confirm the proton emitting state to be the Iπ = 1+ state, irrespective of the strength of the Coriolis interaction. This study provides us with an opportunity to look into the details of wave functions of deformed odd-odd nuclei to which the proton emission halflives are quite sensitive.

Objectives Smoking, the leading cause of disease and death in the United States, has been linked to a number of health conditions including cancer and cardiovascular disease. While people with a disability have been shown to be more likely to report smoking, little is known about the prevalence of smoking by type of disability, particularly for adults younger than 50 years of age. Methods We used data from the 2009–2011 National Health Interview Survey to estimate the prevalence of smoking by type of disability and to examine the association of functional disability type and smoking among adults aged 18–49 years. Results Adults with a disability were more likely than adults without a disability to be current smokers (38.8% vs. 20.7%, pdisability was associated with statistically significantly higher odds of current smoking (adjusted odds ratio = 1.57, 95% confidence interval 1.40, 1.77). Conclusions The prevalence of current smoking for adults was higher for every functional disability type than for adults without a disability. By understanding the association between smoking and disability type among adults younger than 50 years of age, resources for cessation services can be better targeted during the ages when increased time for health improvement can occur.

Full text: Recently, many studies have been published attempting to explain the role of the 0g 9/2 orbital in the high spin excited states of nuclei in the region of the mass A=50-80, especially very neutron rich nuclei like, for example 59-66 Fe [1], 65,67 Cu [2], 70,80 Ge [3,4] nuclei and those with odd mass number like As, Ge and Ga [5]. Stefanescu et al. [6] demonstrated the presence of bands in the neutron-rich isotopes Ga formed from excitation of a proton to the 0g 9/2 orbital and Cheal et al. [7] revealed, from the study of the spins and moments of the ground state, changes in nuclear structure of the odd Ga isotopes between N = 40 and N 50, indicating a change in the energy gap between the 0g 9/2 orbital and the pf shell. In this work, we have performed a systematic study of odd-odd 64,66,68,70 Ga nuclei to examine the behavior of the 0g 9/2 orbital with an increasing number of neutrons. We have compared the predictions of the Large Scale Shell Model, obtained using the Antoine code [8] with the FPG [9] and JUN45 [10] effective interactions, with the experimental results obtained with in-beam gamma-ray spectroscopy experiments performed at University of Sao Paulo using SACI-PERERE spectrometer and at Florida State University using the Clover Array System. We have also performed calculations to study 67 Ge, an odd nucleus in the same mass region, in order to verify the behavior of the effective interactions in a nucleus without the proton-neutron interaction.

2012-01-01

Background The prevalence, determinants and prognosis of pulmonary hypertension among long-term hemodialysis patients in the USA are poorly understood. Methods A cross-sectional survey of prevalence and determinants of pulmonary hypertension was performed, followed by longitudinal follow-up for all-cause mortality. Pulmonary hypertension was defined as an estimated systolic pulmonary artery pressure of >35 mmHg using echocardiograms performed within an hour after the end of dialysis. Results Prevalent in 110/288 patients (38%), the independent determinants of pulmonary hypertension were the following: left atrial diameter (odds ratio 10.1 per cm/m2, P pulmonary hypertension (53%, CMR 168.9/1000 patient-years) and 39 among 178 without pulmonary hypertension (22%, CMR 52.5/1000 patient-years) [unadjusted hazard ratio (HR) for death 2.12 (95% confidence interval 1.41–3.19), P pulmonary hypertension remained an independent predictor for all-cause mortality [HR 2.17 (95% confidence interval 1.31–3.61), P pulmonary hypertension is common and is strongly associated with an enlarged left atrium and poor long-term survival. Reducing left atrial size such as through volume control may be an attractive target to improve pulmonary hypertension. Improving pulmonary hypertension in this group of patients may improve the dismal outcomes. PMID:22290987

Complete text of publication follows. Signature inversion in the A ∼ 100 region has been reported earlier only in the case of the odd-odd 98 Rh nucleus. Our studies on the 100-103 Rh isotopes and a close inspection of the known πg 9/2 νh 11/ 2 bands of the Rh (Z = 45) and Ag (Z = 47) isotopes revealed that the signature splitting effects, earlier considered as quenchings of signature splitting, are not only quenchings but signature inversions. Indeed, the energetically favored signature at low spins in these πg 9/2 νh 11/2 bands is the α = 1 branch (odd spins) instead of the expected α = 0 branch (even spins). The systematic occurrence of signature inversion in this mass region is discussed in Refs. together with attempts to understand its behavior qualitatively. Among many attempts for interpreting the mechanism of signature inversion in odd-odd nuclei, a model using an axially symmetric rotor plus two quasi-particles has already been successfully applied to describe the observed signature inversions in the A ∼ 80 and A ∼ 160 mass regions. According to this model the signature inversion is caused by the competition between the Coriolis and the proton-neutron residual interactions in low K space. Such calculations have been also successfully applied to the π g9/2 νh 11/2 bands in the odd-odd 98 Rh and 102 Rh nuclei. Recent observations of chiral band structures in the nearby Rh nuclei suggest a possibility of triaxiality in these nuclei, too. In the present work we examined the possible influence of triaxiality on the signature inversion using a triaxial rotor plus two-quasiparticle model and compared the results with the experimental data of 98 Rh and 102 Rh. The calculations provided a better agreement with the experiment than the axially symmetric calculations. Compared to the axially symmetric case, the triaxiality applied in the Hamiltonian enlarges the amplitudes of high-spin signature zigzags at small triaxial deformation and might push the

There is little information concerning the prevalence and clinical correlates of increased pulmonary thallium-201 uptake during dipyridamole thallium-201 stress imaging. Accordingly, the clinical characteristics and quantitative thallium-201 findings were correlated with quantitative lung/heart thallium-201 ratio in 87 patients undergoing dipyridamole thallium-201 stress testing. Nineteen patients (22%) had an elevated ratio (greater than 0.51). These patients were more likely to have had an infarction, to be taking beta blockers, and have a lower rate-pressure product after dipyridamole administration than those with a normal ratio (p less than 0.03). An elevated ratio was associated with a greater likelihood of initial, redistribution and persistent defects, as well as left ventricular cavity dilatation on thallium-201 imaging (p less than 0.05). In addition, the number of myocardial segments demonstrating initial, redistribution and persistent defects was also greater in patients with increased ratios (p less than 0.03). Multivariate analysis demonstrated that the presence of redistribution and left ventricular cavity dilatation were the most significant correlates of lung/heart thallium-201 ratio. It is concluded that the prevalence of increased lung/heart thallium-201 ratio with dipyridamole thallium-201 stress imaging is similar to that seen with exercise stress imaging. As with exercise thallium-201 imaging, increased pulmonary thallium-201 uptake may be a marker of functionally more significant coronary artery disease

Full Text Available Background: Smoking is a major modifiable risk factor for premature mortality. Estimating the smoking-attributable burden is important for public health policy. Typically, prevalence- or smoking impact ratio (SIR-based methods are used to derive estimates, but there is controversy over which method is more appropriate for country-specific estimates. We compared smoking-attributable fractions (SAFs of deaths estimated by these two methods. Methods: To estimate SAFs in 2012, we used several different prevalence-based approaches using no lag and 10- and 20-year lags. For the SIR-based method, we obtained lung cancer mortality rates from the Korean Cancer Prevention Study (KCPS and from the United States-based Cancer Prevention Study-II (CPS-II. The relative risks for the diseases associated with smoking were also obtained from these cohort studies. Results: For males, SAFs obtained using KCPS-derived SIRs were similar to those obtained using prevalence-based methods. For females, SAFs obtained using KCPS-derived SIRs were markedly greater than all prevalence-based SAFs. Differences in prevalence-based SAFs by time-lag period were minimal among males, but SAFs obtained using longer-lagged prevalence periods were significantly larger among females. SAFs obtained using CPS-II-based SIRs were lower than KCPS-based SAFs by >15 percentage points for most diseases, with the exceptions of lung cancer and chronic obstructive pulmonary disease. Conclusions: SAFs obtained using prevalence- and SIR-based methods were similar for males. However, neither prevalence-based nor SIR-based methods resulted in precise SAFs among females. The characteristics of the study population should be carefully considered when choosing a method to estimate SAF.

Full Text Available Background. Peer victimization (bullying is a universal phenomenon with detrimental effects. The aim of this study is to determine the prevalence and factors of bullying among grades 7 and 8 middle school students in Kuwait. Methods. The study is a cross-sectional study that includes a sample of 989 7th and 8th grade middle school students randomly selected from schools. The Revised Olweus Bully/Victim Questionnaire was used to measure different forms of bullying. After adjusting for confounding, logistic regression identified the significant associated factors related to bullying. Results. Prevalence of bullying was 30.2 with 95% CI 27.4 to 33.2% (3.5% bullies, 18.9% victims, 7.8% bully victims. Children with physical disabilities and one or both non-Kuwaiti parents or children with divorced/widowed parents were more prone to be victims. Most victims and bullies were found to be current smokers. Bullies were mostly in the fail/fair final school grade category, whereas victims performed better. The logistic regression showed that male gender (adjusted odds ration = 1.671, p=0.004, grade 8 student (adjusted odds ratio = 1.650, p=0.004, and student with physical disabilities (adjusted odds ratio = 1.675, p=0.003, were independently associated with bullying behavior. Conclusions. There is a need for a school-wide professional intervention program and improvement in the students’ adjustment to school environment to control bullying behavior.

To assess the prevalence and current suffering of experienced abuse in healthcare, to present the socio-demographic background for women with a history of abuse in healthcare and to assess the association between abuse in healthcare and selected obstetric characteristics. Cross-sectional study. Routine antenatal care in six European countries. In total 6923 pregnant women. Cross-tabulation and Pearson's chi-square was used to study prevalence and characteristics for women reporting abuse in healthcare. Associations with selected obstetric factors were estimated using multiple logistic regression analysis. Abuse in healthcare, fear of childbirth and preference for birth by cesarean section. One in five pregnant women attending routine antenatal care reported some lifetime abuse in healthcare. Prevalence varied significantly between the countries. Characteristics for women reporting abuse in healthcare included a significantly higher prevalence of other forms of abuse, economic hardship and negative life events as well as a lack of social support, symptoms of post-traumatic stress and depression. Among nulliparous women, abuse in healthcare was associated with fear of childbirth, adjusted odds ratio 2.25 (95% CI 1.23-4.12) for severe abuse in healthcare. For multiparous women only severe current suffering from abuse in healthcare was significantly associated with fear of childbirth, adjusted odds ratio 4.04 (95% CI 2.08-7.83). Current severe suffering from abuse in healthcare was significantly associated with the wish for cesarean section, and counselling for fear of childbirth for both nulli- and multiparous women. Abuse in healthcare among women attending routine antenatal care is common and for women with severe current suffering from abuse in healthcare, this is associated with fear of childbirth and a wish for cesarean section. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

The aim of the study was to clarify the relationship between current pet ownership, passive smoking, and allergic diseases among the Japanese children. From 1995 to 2001, we distributed the Japanese edition of the questionnaire of the American Thoracic Society and the Division of Lung Diseases (ATS-DLD) to survey allergic diseases among 35,552 6-yr-old children at primary school in the city of Himeji, Japan. We analyzed the data by multiple logistic regression and calculated adjusted odds ratios for environmental factors, including passive smoking and pet (dog and/or cat) ownership. There were no significant relationships between the prevalence of asthma and current pet ownership and passive smoking. However, current cat ownership was related to a significantly lower prevalence of atopic dermatitis [adjusted odds ratio (aOR) 0.79, 95% confidence interval (CI) 0.67-0.93], allergic rhinitis (aOR: 0.71, 95% CI 0.57-0.89) and Japanese cedar pollinosis (aOR 0.57, 95% CI 0.44-0.75). Strikingly, passive smoking was also related to a significantly lower prevalence of allergic rhinitis (aOR 0.83, 95% CI 0.77-0.89) and Japanese cedar pollinosis (aOR 0.81, 95% CI 0.74-0.88). Current cat ownership was associated with a lower prevalence of atopic dermatitis, allergic rhinitis, and Japanese cedar pollinosis. In addition, passive smoking was also associated with a lower prevalence of allergic rhinitis and Japanese cedar pollinosis.

1. Effects of rearing conditions on behavioural problems were investigated in a cohort study of commercial flocks of laying hens housed in 2 different loose housing systems. The sample population was 120 385 laying hens from 59 flocks of various hybrids at 21 different farms. 2. Logistic regression modelling was used to test the effects of selected factors on floor eggs, cloacal cannibalism and feather pecking. In addition to early access to perches or litter, models included hybrid, stocking density, group size, housing system, age at delivery, identical housing system at the rearing farm and at the production farm and, in models for floor eggs and cloacal cannibalism, nest area per hen. Odds ratios were calculated from the results of the models to allow risk assessment. 3. No significant correlations were found between the prevalence of floor eggs, cloacal cannibalism and feather pecking. 4. Access to perches from not later than the 4th week of age decreased the prevalence of floor eggs during the period from start-of-lay until 35 weeks of age, odds ratio 0-30 (Pfeather pecking.

We conducted an observational study to estimate prevalence and risk factors for Salmonella spp. and Campylobacter spp. caecal colonization in poultry. Eighty-one broiler chicken and 59 turkey flocks selected among flocks slaughtered in the province of Quebec, Canada, were included in the study. Flock status was evaluated by culturing pooled caecal contents from about 30 birds per flock. Exposure to potential risk factors was evaluated with a questionnaire. Odds ratios were computed using multivariable logistic regression. The prevalence of Salmonella-positive flocks was 50% (95% CI: 37, 64) for chickens and 54% (95% CI: 39, 70) for turkeys, respectively. Odds of Salmonella colonization were 2.6 times greater for chicken flocks which failed to lock the chicken house permanently. In turkeys, odds of Salmonella colonization were 4.8-7.7 times greater for flocks which failed to be raised by hatchery. The prevalence of Campylobacter-positive flocks was 35% (95% CI: 22, 49) for chickens and 46% (95% CI: 30, 62) for turkeys. Odds of colonization were 4.1 times higher for chicken flocks raised on farms with professional rodent control and 5.2 times higher for flocks with manure heap >200m from the poultry house, and also increased with the number of birds raised per year on the farm and with the age at slaughter. For turkeys, odds of Campylobacter flock colonization were 3.2 times greater in flocks having a manure heap at

The aim of this study was to examine the pattern of comorbidity among obsessive-compulsive personality disorder (OCPD) and other personality disorders (PDs) in a sample of 400 psychiatric inpatients. PDs were assessed using the Semistructured Clinical Interview for DSM-III-R Personality Disorders (SCID-II). Odds ratios (ORs) were calculated to determine significant comorbidity among OCPD and other axis II disorders. The most elevated odds ratios were found for the cooccurrence of OCPD with cluster A PDs (the "odd" PDs, or paranoid and schizoid PDs). These results are consistent with those of previous studies showing a higher cooccurrence of OCPD with cluster A than with cluster C ("anxious") PDs. In light of these observations, issues associated with the nosologic status of OCPD within the Diagnostic and Statistical Manual of Mental Disorders clustering system remain unsettled.

Epidemiologic studies have suggested beneficial effects of flavonoids on cardiovascular disease. Cocoa and particularly dark chocolate are rich in flavonoids and recent studies have demonstrated blood pressure lowering effects of dark chocolate. However, limited data are available on the association of chocolate consumption and the risk of coronary heart disease (CHD). We sought to examine the association between chocolate consumption and prevalent CHD. We studied in a cross-sectional design 4970 participants aged 25-93 years who participated in the National Heart, Lung, and Blood Institute (NHLBI) Family Heart Study. Chocolate intake was assessed through a semi-quantitative food frequency questionnaire. We used generalized estimating equations to estimate adjusted odds ratios. Compared to subjects who did not report any chocolate intake, odds ratios (95% CI) for CHD were 1.01 (0.76-1.37), 0.74 (0.56-0.98), and 0.43 (0.28-0.67) for subjects consuming 1-3 times/month, 1-4 times/week, and 5+ times/week, respectively (p for trend Consumption of non-chocolate candy was associated with a 49% higher prevalence of CHD comparing 5+/week vs. 0/week [OR = 1.49 (0.96-2.32)]. These data suggest that consumption of chocolate is inversely related with prevalent CHD in a general United States population. Published by Elsevier Ltd.

A systematic study of two-quasiparticle bands of the proton-rich odd-odd nuclei in the mass A∼70-80 region is performed using the projected shell model approach. The study includes Br, Rb, and Y isotopes with N=Z+2 and Z+4. We describe the energy spectra and electromagnetic transition strengths in terms of the configuration mixing of the angular-momentum projected multi-quasiparticle states. Signature splitting and signature inversion in the rotational bands are discussed and are shown to be well described. A preliminary study of the odd-odd N=Z nucleus 74 Rb, using the concept of spontaneous symmetry breaking is also presented

High spin states of the odd-odd 162 Lu nucleus have been studied via 147 Sm( 19 F, 4nγ) 162 Lu reaction at 95MeV beam energy. Level scheme for yrast band based on π[h 11/2 ] υ[i 13/2 ] quasiparticle configuration was established up to I π =(23 - ) for the first time. This band shows the signature inversion in energy before backbending generally appeared in this mass region. It is stressed that the signature splitting in 162 Lu is larger than that in the 160 Tm nucleus. (orig.)

Purpose The association between stomach cancer and colorectal cancer is controversial. The purpose of this study was to determine the synchronous prevalence of colorectal neoplasms in patients with stomach cancer. Methods A total of 123 patients with stomach cancer (86 male) and 246 consecutive, age- and sex-matched persons without stomach cancer were analyzed from July 2005 to June 2010. All of them underwent colonoscopy within 6 months after undergoing gastroscopy. Results The prevalence of colorectal neoplasms was significantly higher in the stomach cancer group (35.8%) than in the control group (17.9%) (P neoplasms were more prevalent in the patients with stomach cancer (odds ratio [OR], 3.10; 95% confidence interval [CI], 1.71 to 5.63). In particular, the difference in the prevalence of colorectal neoplasms was more prominent in the patients above 50 years old (OR, 3.54; 95% CI, 1.80 to 6.98). Conclusion The results showed that the synchronous prevalence of colorectal neoplasms was higher in patients with stomach cancer than in those without stomach cancer. Therefore, patients with stomach cancer should be regarded as a high-risk group for colorectal neoplasms, and colonoscopy should be recommended for screening. PMID:22102975

We review the theory of odd-frequency pairing in superconducting heterostructures, where an odd-frequency pairing component is induced near interfaces. A general description of the superconducting proximity effect in a normal metal or a ferromagnet attached to an unconventional superconductor (S) is given within quasiclassical kinetic theory for various types of symmetry state in S. Various possible symmetry classes in a superconductor are considered which are consistent with the Pauli principle: even-frequency spin-singlet even-parity (ESE) state, even-frequency spin-triplet odd-parity (ETO) state, odd-frequency spin-triplet even-parity (OTE) state and odd-frequency spin-singlet odd-parity (OSO) state. As an example, we consider a junction between a diffusive normal metal (DN) and a p-wave superconductor (even-frequency spin-triplet odd-parity symmetry), where the pairing amplitude in DN belongs to an odd-frequency spin-triplet even-parity symmetry class. We also discuss the manifestation of odd-frequency pairing in conventional superconductor/normal (S/N) proximity systems and its relation to the classical McMillan-Rowell oscillations.

Primary ovarian insufficiency before the age of 40 years affects 1% of the female population and is characterized by permanent cessation of menstruation. Genetic causes include FMR1 expansion mutations. Previous studies have estimated mutation prevalence in clinical referrals for primary ovarian insufficiency, but these are likely to be biased as compared with cases in the general population. The prevalence of FMR1 expansion mutations in early menopause (between the ages of 40 and 45 years) has not been published. We studied FMR1 CGG repeat number in more than 2,000 women from the Breakthrough Generations Study who underwent menopause before the age of 46 years. We determined the prevalence of premutation (55-200 CGG repeats) and intermediate (45-54 CGG repeats) alleles in women with primary ovarian insufficiency (n = 254) and early menopause (n = 1,881). The prevalence of the premutation was 2.0% in primary ovarian insufficiency, 0.7% in early menopause, and 0.4% in controls, corresponding to odds ratios of 5.4 (95% confidence interval = 1.7-17.4; P = 0.004) for primary ovarian insufficiency and 2.0 (95% confidence interval = 0.8-5.1; P = 0.12) for early menopause. Combining primary ovarian insufficiency and early menopause gave an odds ratio of 2.4 (95% confidence interval = 1.02-5.8; P = 0.04). Intermediate alleles were not significant risk factors for either early menopause or primary ovarian insufficiency. FMR1 premutations are not as prevalent in women with ovarian insufficiency as previous estimates have suggested, but they still represent a substantial cause of primary ovarian insufficiency and early menopause.

To describe HIV testing uptake and prevalence among adolescents and adults in a home-based HIV counseling and testing program in western Kenya. Since 2007, the Academic Model Providing Access to Healthcare program has implemented home-based HIV counseling and testing on a large scale. All individuals aged ≥13 years were eligible for testing. Data from 5 of 8 catchments were included in this analysis. We used descriptive statistics and multivariate logistic regression to examine testing uptake and HIV prevalence among adolescents (13-18 years), younger adults (19-24 years), and older adults (≥25 years). There were 154,463 individuals eligible for analyses as follows: 22% adolescents, 19% younger adults, and 59% older adults. Overall mean age was 32.8 years and 56% were female. HIV testing was high (96%) across the following 3 groups: 99% in adolescents, 98% in younger adults, and 94% in older adults (P < 0.001). HIV prevalence was higher (11.0%) among older adults compared with younger adults (4.8%) and adolescents (0.8%) (P < 0.001). Those who had ever previously tested for HIV were less likely to accept HIV testing (adjusted odds ratio: 0.06, 95% confidence interval: 0.05 to 0.07) but more likely to newly test HIV positive (adjusted odds ratio: 1.30, 95% confidence interval: 1.21 to 1.40). Age group differences were evident in the sociodemographic and socioeconomic factors associated with testing uptake and HIV prevalence, particularly, gender, relationship status, and HIV testing history. Sociodemographic and socioeconomic factors were independently associated with HIV testing and prevalence among the age groups. Community-based treatment and prevention strategies will need to consider these factors.

To assess the prevalence of primary headaches (HA) in adults with temporomandibular disorders (TMD) who were assessed in a specialty orofacial pain clinic, as well as in controls without TMD. The sample consisted of 158 individuals with TMD seen at a university-based specialty clinic, as well as 68 controls. The Research Diagnostic Criteria for TMD were used to diagnose the TMD patients. HAs were assessed using a structured interview and classified according to the Second Edition of the International Classification for Headache Disorders. Data were analyzed by chi-square tests with a significance level of 5% and odds ratio (OR) tests with a 95% confidence interval (CI). HAs occurred in 45.6% of the control group (30.9% had migraine and 14.7% had tension-type headache [TTH]) and in 85.5% of individuals with TMD. Among individuals with TMD, migraine was the most prevalent primary HA (55.3%), followed by TTH (30.2%); 14.5% had no HA. In contrast to controls, the odds ratio (OR) for HA in those with TMD was 7.05 (95% confidence interval [CI] = 3.65-13.61; P = .000), for migraine, the OR was 2.76 (95% CI = 1.50-5.06; P = .001), and for TTH, the OR was 2.51 (95% CI = 1.18-5.35; P = .014). Myofascial pain/arthralgia was the most common TMD diagnosis (53.2%). The presence of HA or specific HAs was not associated with the time since the onset of TMD (P = .714). However, migraine frequency was positively associated with TMD pain severity (P = .000). TMD was associated with increased primary HA prevalence rates. Migraine was the most common primary HA diagnosis in individuals with TMD.

Obesity is a growing public health concern and is more prevalent among low-income and minority populations. Food insecurity may increase the odds of obesity in children. We investigated the association between food insecurity and obesity among low-income, Hispanic, mother-child dyads (n = 74). The United States Department of Agriculture 18-item Household Food Security Survey was used to determine food security status. The majority of households were food insecure (74 %) and one-third (30 %) of children were obese. Food insecurity increased the odds of childhood obesity (OR 10.2; 95 % CI 1.2, 85.5) with stronger associations found within households where mothers were also overweight/obese compared to normal weight (p-for interaction food insecurity and childhood obesity were high among this low-income Hispanic sample. Future studies should elucidate the mechanisms through which food insecurity impacts childhood obesity.

AIM: To determine an optimal cutoff value for abnormal splenic artery diameter/proper hepatic artery diameter (S/P) ratio in cirrhosis-induced portal hypertension. METHODS: Patients with cirrhosis and portal hypertension (n = 770) and healthy volunteers (n = 31) underwent volumetric computed tomography three-dimensional vascular reconstruction to measure the internal diameters of the splenic artery and proper hepatic artery to calculate the S/P ratio. The cutoff value for abnormal S/P ratio was determined using receiver operating characteristic curve analysis, and the prevalence of abnormal S/P ratio and associations between abnormal S/P ratio and major complications of portal hypertension were studied using logistic regression. RESULTS: The receiver operating characteristic analysis showed that the cutoff points for abnormal splenic artery internal diameter and S/P ratio were > 5.19 mm and > 1.40, respectively. The sensitivity, specificity, positive predictive value, and negative predictive value were 74.2%, 45.2%, 97.1%, and 6.6%, respectively. The prevalence of an abnormal S/P ratio in the patients with cirrhosis and portal hypertension was 83.4%. Patients with a higher S/P ratio had a lower risk of developing ascites [odds ratio (OR) = 0.708, 95%CI: 0.508-0.986, P = 0.041] and a higher risk of developing esophageal and gastric varices (OR = 1.483, 95%CI: 1.010-2.175, P = 0.044) and forming collateral circulation (OR = 1.518, 95%CI: 1.033-2.230, P = 0.034). After splenectomy, the portal venous pressure and maximum and mean portal venous flow velocities were reduced, while the flow rate and maximum and minimum flow velocities of the hepatic artery were increased (P portal hypertension, and it can be used as an important marker of splanchnic hemodynamic disturbances.

Asthma is a chronic inflammatory airway disease whose prevalence has increased, especially in developed countries; the results of studies of asthma prevalence vary in different populations and even within the same country; in Mexico we observed fluctuations in prevalence of asthma from 7% to 33%. To determine the prevalence of asthma and severity of symptoms as risk indicators in school population in cities in various states of Mexico. A descriptive study of detection of asthma prevalence and analytical-comparative observational study of determination of symptoms of asthma. The surveys were applied to preschool, elementary, middle and high school population, in the cities of Puebla, Puebla; Tulancingo, Hidalgo; Tlaxcala, Tlaxcala, and Cancún, Quintana Roo; new validated questionnaire was used as instrument: Asthma Diagnostic Questionnaire for Epidemiologic Studies, consisting of eight questions with summation value for diagnosis. 8,754 surveys showed a 14% prevalence in Puebla, 17% in Tulancingo, 7% in Tlaxcala, and 14% in Cancún; average in four cities surveyed was 13%; the strength of association with asthma symptoms in descending order with significant odds ratio were: recurrent wheezing, breathlessness, chest tightness, recurrent cough, cough cold, recurrent cold symptoms, predominantly nocturnal cough, cough that increases with exercise. The average prevalence of asthma in the surveyed cities was 13% and the main symptoms indicators of risk of asthma in school children were: recurrent wheezing, breathlessness, chest tightness and recurrent cough.

The triglyceride/HDL cholesterol ratio, as a surrogate marker of insulin resistance, may be associated to presence of subclinical carotid atherosclerosis in postmenopausal women. The aim of this study was to explore this association. Women (last menstrual period≥2 years) in primary prevention up to 65 years of age were recruited. Association between the triglyceride/HDL cholesterol (HDL-C) ratio and presence of carotid plaque, assessed by ultrasonography, was analyzed. ROC analysis was performed, determining the precision of this ratio to detect carotid plaque. A total of 332 women (age 57±5 years) were recruited. Triglyceride/HDL-C ratio was 2.35±1.6. Prevalence of carotid plaque was 29%. Women with carotid plaque had higher triglyceride/HDL-C ratios (3.33±1.96 vs. 2.1±1.2, P<.001) than women with no carotid plaque. A positive relationship was seen between quintiles of this ratio and prevalence of carotid plaque (p<.001). Regardless of other risk factors, women with higher triglyceride/HDL-C ratios were more likely to have carotid plaque (odds ratio 1.47, 95% confidence interval 1.20-1.79, P<.001). The area under the curve of the triglyceride/HDL-C ratio to detect carotid plaque was .71 (95% confidence interval .65 to .76), and the optimal cut-off point was 2.04. In postmenopausal women in primary prevention, insulin resistance, estimated from the triglyceride/HDL-C ratio, was independently associated to a greater probability of carotid plaque. A value of such ratio greater than 2 may be used for assessing cardiovascular risk in this particular group of women. Copyright © 2016 SEEN. Publicado por Elsevier España, S.L.U.

Full Text Available Aim: Gastrointestinal parasitism is a serious constraint affecting goat production in the Philippines. This study aimed to determine the prevalence and associated risk factors of gastrointestinal nematode infection in goat-populated barangays of Baybay City, Leyte. Materials and Methods: A total of 81 households or farms were interviewed, and 450 goats were sampled for fecalysis. Fecal egg count along with egg morphological identification and coproculture for third stage larvae identification were conducted. Descriptive statistics and logistic regression analyses were carried out to determine the farm- and animal-level prevalence and risk factors. Results: Fecalysis revealed the presence of strongyle and Trichuris spp. with a farm-level prevalence of 100% and 4.94%, respectively; and animal-level prevalence of 96.22% and 4.44%, respectively. The identified strongyle genera per barangay were Haemonchus spp. (34.79%, Trichostrongylus spp. (33.29%, Oesophagostomum spp. (24.21%, Cooperia spp. (6.93%, and Chabertia spp. (0.79%. Goats older than 12 months were four times more likely to present high strongyle burden when compared to goats <6 months. With each month increase in goat’s age, the odds of acquiring strongyle infection also increased by 1.07 times. Animals kept in goat house with cemented flooring have lower odds of acquiring strongyle (odds ratio=0.12. Goats raised for leisure purposes and fed with carabao grass (Paspalum conjugatum were 8.12 and 5.52 times more likely to acquire Trichuris, respectively. Conclusion: Most of the backyard goat raisers in Baybay City, Leyte, do not practice sound helminth control measures as shown by the high prevalence of gastrointestinal nematodes. The most relevant risk factors for gastrointestinal nematode infection were the age of the goat, type of goat house’s flooring, purpose of raising goats, and feeding practices.

Epidemiologic evidence on long working hour and diabetes has been conflicting. We examined the association between overtime work and prevalence of diabetes among Japanese workers. The subjects were 40,861 employees (35,170 men and 5,691 women), aged 16 to 83 years, of 4 companies in Japan. Hours of overtime were assessed using self-reported questionnaires. Diabetes was defined as a fasting plasma glucose ≥126 mg/dl (7.0 mmol/l), hemoglobin A1c ≥6.5% (48 mmol/mol), or current use of anti-diabetic drug. Multiple logistic regression analysis was used to calculate odds ratio of diabetes for each category of overtime. After adjustment for age, sex, company, smoking, and BMI, there was a suggestion of U-shaped relationship between overtime work and prevalence of diabetes (P for quadratic trend = 0.07). Compared with those who worked hours of overtime per month, the adjusted odds ratios (95% confidence interval) of diabetes were 0.86 (0.77-0.94), 0.69 (0.53-0.89), and 1.03 (0.72-1.46) for those who worked 45-79, 80-99, and ≥100 hours of overtime per month, respectively. In one company (n = 33,807), where other potential confounders including shift work, job position, type of department, alcohol consumption, sleep duration, leisure time physical activity, and family history of diabetes was additionally adjusted for, similar result was obtained (P for quadratic trend = 0.05). Long hours of overtime work may not be associated with increased prevalence of diabetes among Japanese workers.

Previous studies demonstrated conflicting results about the association of sleep duration and hypertension. Given the potential relationship between sleep quality and hypertension, this study aimed to investigate the interaction of self-reported sleep duration and sleep quality on hypertension prevalence in adult Chinese males. We undertook a cross-sectional analysis of 4144 male subjects. Sleep duration were measured by self-reported average sleep time during the past month. Sleep quality was evaluated using the standard Pittsburgh Sleep Quality Index. Hypertension was defined as blood pressure level ≥140/90 mm Hg or current antihypertensive treatment. The association between hypertension prevalence, sleep duration, and sleep quality was analyzed using logistic regression after adjusting for basic cardiovascular characteristics. Sleep duration shorter than 8 hours was found to be associated with increased hypertension, with odds ratios and 95% confidence intervals (CIs) of 1.25 (95% CI, 1.03-1.52) for 7 hours, 1.41 (95% CI, 1.14-1.73) for 6 hours, and 2.38 (95% CI, 1.81-3.11) for quality as the reference, good, poor, and very poor sleep quality were associated with hypertension, with odds ratios of 1.20 (95% CI, 1.01-1.42), 1.67 (95% CI, 1.32-2.11), and 2.32 (95% CI, 1.67-3.21), respectively. More importantly, further investigation of the association of different combinations of sleep duration and quality in relation to hypertension indicated an additive interaction. There is an additive interaction of poor sleep quality and short sleep duration on hypertension prevalence. More comprehensive measurement of sleep should be performed in future studies.

To explore the prevalence rate of faecal incontinence in community-dwelling older people, associated factors, impact on quality of life and practices in managing faecal incontinence. Using a cross-sectional design, 600 older people aged 60+ were randomly selected from a population of 2916 in Bali, Indonesia using a simple random sampling technique. Three hundred and three participants were interviewed (response rate 51%). The prevalence of faecal incontinence was 22.4% (95% confidence interval (CI) 18.0-26.8). Self-reported constipation (odds ratio (OR) 3.68, 95% CI 1.87-7.24) and loose stools (OR 2.66, 95% CI 1.47-4.78) were significantly associated with faecal incontinence. There was a strong positive correlation between total bowel control score and total quality-of-life score (P Bali. © 2014 ACOTA.

Infection with Helicobacter pylori (H. pylori) is acquired mainly in childhood, with studies demonstrating this is related to living conditions. Effects of sibling number and birth order on prevalence of infection have not been extensively studied. The authors performed a cross-sectional survey of adults, aged between 50 and 59 years, previously involved in a community-screening programme for H. pylori in Leeds and Bradford, UK. Prevalence of H. pylori was assessed at baseline with urea breath test. All individuals who were alive, and could be traced, were contacted by postal questionnaire in 2003 obtaining information on number of siblings and birth order. Data concerning childhood socioeconomic conditions were stored on file from the original study. 3928 (47%) of 8407 original participants provided data. Prevalence of infection increased according to sibling number (20% in those with none vs 63% with eight or more). Controlling for childhood socioeconomic conditions and birth order using multivariate logistic regression, infection odds were substantially increased with three siblings compared with none [odds ratio (OR) 1.51; 95% confidence interval (CI) 1.06-2.15], and a gradient of effect continued up to eight or more siblings (OR 5.70; 95% CI 2.92-11.14). Odds of infection also increased substantially with birth order, but the positive gradient disappeared on adjustment for sibling number and childhood socioeconomic conditions. : In this cross section of UK adults, aged 50-59 years, sibling number in the household, but not birth order, was independently associated with prevalence of H. pylori infection.

The aim of the study was to determine the association between the prevalence of clinically significant depression and age in a large representative sample of elderly German people. In the second follow-up (2005-2007) of the ESTHER cohort study, the 15-item geriatric depression scale (GDS-15) as well as a sociodemographic and clinical questionnaire were administered to a representative sample of 8270 people of ages 53 to 80 years. The prevalence of clinically significant depression was estimated using a GDS cut-off score of 5/6. Prevalence rates were estimated for the different age categories. Association between depression and age was analyzed using logistic regression, adjusted for gender, co-morbid medical disorders, education, marital status, physical activity, smoking, self-perceived cognitive impairment, and anti-depressive medication. Of the participants, 7878 (95.3%) completed more than twelve GDS items and were included in the study. The prevalence of clinically significant depression was 16.0% (95%CI = [15.2; 16.6]). The function of depression prevalence dependent on age group showed a U-shaped pattern (53-59: 21.0%, CI = [18.9; 23.3]; 60-64: 17.7%, CI = [15.7; 19.7]; 65-69: 12.6%, CI = [11.2; 14.0]; 70-74: 14.4%, CI = [12.6; 16.0]; 75-80: 17.1%, CI = [14.9; 19.4]). Adjusted odds ratios showed that the chances of being depressive decrease with the age category but remain relatively stable for people aged 65 and over. The prevalence of depression in the elderly seems to be associated with the age category. Adjusted odds ratios showed that people aged 60 and older had lower chances of being depressive than people aged 53 to 59 years. Copyright © 2011 John Wiley & Sons, Ltd.

. The prevalence of asthma was 4.7%. The prevalence odds ratio of asthma in conscripts with a birth weight below 2,501 g was 1.5 (95% confidence interval = 0.7–3.1) compared with conscripts with a birth weight of 3,001–3,500 g, adjusted for gestational age and potential confounders. The adjusted prevalence odds...... ratio among conscripts born before 34 gestational weeks was 0.8 (95% confidence interval = 0.3–2.0) compared with conscripts born at term. The prevalence of atopic dermatitis was 1.0%. The prevalence odds ratio of atopic dermatitis among those with a birth weight below 2,501 g was 3.0 (95% confidence...... interval = 0.8–11.9) compared with those whose birth weight was between 3,001 and 3,500 g. Men whose gestational age had been below 34 weeks had an adjusted prevalence odds ratio of 0.3 (95% confidence interval = 0.0–3.1). These findings indicate that fetal growth retardation rather than preterm delivery...

Full Text Available Background. Because of the epidemic of metabolic syndrome (MS in Australian Aboriginals known for their higher cardiovascular mortality and shorter life expectancy, we analyzed the possible relationship of their MS risks with the current dietary custom. Methods. The subjects were 84 people aged 16–79 years. The health examination was conducted according to the basic protocol of WHO-CARDIAC (Cardiovascular Diseases and Alimentary Comparison Study. Results. The highest prevalence among MS risks was abdominal obesity (over 60%. After controlling for age and sex, the odds of obesity decreased significantly with high level of urinary magnesium/creatinine ratio (Mg/cre (OR, 0.11; 95% CI, 0.02–0.57; P<.05. The significant inverse associations of fat intake with Mg/cre and of fast food intake with urinary taurine/creatinine ratio were revealed. Conclusions. The high prevalence of obesity in the Aboriginal people of this area may partly be due to the reduction of beneficial nutrients intake including Mg and taurine.

Brucellosis is a major constraint for small-scale goat farming systems in Mexico. This study estimated the prevalence of testing positive to brucellosis and identified and quantified risk factors in goats from small-scale farms of Michoacán that had participated in a brucellosis campaign (i.e. vaccination, serological testing, culling and awareness) and of Jalisco that had negligible brucellosis campaign participation. A cross-sectional serological survey was conducted among 1,713 goats of 83 flocks. The prevalence of testing positive to brucellosis was higher (38%) in Jalisco than in Michoacán (11%). Logistic regression analysis indicated that goats from Michoacán had lower odds to test positive for brucellosis (odds ratio (OR) = 0.32, 95% confidence interval (CI) 0.21-0.48) compared to goats from Jalisco. Goats in zero-grazing systems had lower odds than goats in grazing systems (OR = 0.22, 95% CI 0.09-0.57). When goats were kept in pens with low density (0.002 to 0.22 goat/m(2)), odds was lower (OR = 0.44, 95% CI 0.28-0.67) compared to goats kept in pens with higher density (0.23 to 1 goat/m(2)). Odds was higher for testing positive when farmers bought goats from goat traders (OR = 1.82, 95% CI 1.15-2.87) compared to farmers who did not. If scavenger poultry had access to goat pens, the odds was half (OR = 0.52, 95% CI 0.33-0.83) of those where poultry had no access. Regular disinfection of the pen reduced the odds (OR = 0.66, 95% CI 0.44-0.99) compared to where disinfection was not regular. The brucellosis control campaign was effective in reducing brucellosis seropositivity.

To document the prevalence of overweight, obesity and thinness in 9-10 year old children in Mauritius. 412 boys and 429 girls aged 9-10 years from 23 primary schools were selected using stratified cluster random sampling. All data was cross-sectional and collected via anthropometry and self-administered questionnaire. Outcome measures were BMI (kg/m2), prevalence of overweight, obesity (International Obesity Task Force definitions) and thinness (low BMI for age). Linear and logistic regression analyses, accounting for clustering at the school level, were used to assess associations between gender, ethnicity, school location, and school's academic performance (average) to each outcome measure. The distribution of BMI was marginally skewed with a more pronounced positive tail in the girls. Median BMI was 15.6 kg/m2 in boys and 15.4 kg/m2 in girls, respectively. In boys, prevalence of overweight was 15.8% (95% CI: 12.6, 19.6), prevalence of obesity 4.9% (95% CI: 3.2, 7.4) and prevalence of thinness 12.4% (95% CI: 9.5, 15.9). Among girls, 18.9% (95% CI: 15.5, 22.9) were overweight, 5.1% (95% CI: 3.4, 7.7) were obese and 13.1% (95% CI: 10.2, 16.6) were thin. Urban children had a slightly higher mean BMI than rural children (0.5 kg/m2, 95% CI: 0.01, 1.00) and were nearly twice as likely to be obese (6.7% vs. 4.0%; adjusted odds ratio 1.6; 95% CI: 0.9, 3.5). Creole children were less likely to be classified as thin compared to Indian children (adjusted odds ratio 0.3, 95% CI: 0.2, 0.6). Mauritius is currently in the midst of nutritional transition with both a high prevalence of overweight and thinness in children aged 9-10 years. The coexistence of children representing opposite sides of the energy balance equation presents a unique challenge for policy and interventions. Further exploration is needed to understand the specific causes of the double burden of malnutrition and to make appropriate policy recommendations.

Population-based, cross-sectional. To determine pain prevalence and identify factors associated with chronic pain in individuals with spinal cord injury (SCI) living in Switzerland. Swiss SCI Cohort Study (SwiSCI). Pain characteristics were assessed using an adapted version of the International SCI Pain Basic Data Set, adding one item of the SCI Secondary Conditions Scale to address chronic pain. Pain prevalence was calculated using stratification over demographic, SCI-related and socioeconomic characteristics; odds ratios (adjusted for non-response) for determinants of severity of chronic pain were calculated using stereotype logistic regressions. Pain (in the past week) was reported by 68.9% and chronic pain by 73.5% (significant 36.9%) of all participants (N=1549; 28% female). Most frequently reported pain type was musculoskeletal (71.1%). Back/spine was the most frequently reported pain location (54.6%). Contrasting the 'significant' to the 'none/mild' category of chronic pain, adjusted odds ratios were 1.54 (95% CI: 1.18-2.01; P<0.01) for women (vs men); 6.64 (95% CI: 3.37-11.67; P<0.001) for the oldest age group 61+ (vs youngest (16-30)); 3.41 (95% CI: 2.07-5.62; P<0.001) in individuals reporting severe financial hardship (vs no financial hardship). Individuals reporting specific SCI-related health conditions were 1.41-2.92 (P<0.05) times more likely to report chronic pain as 'significant' rather than 'none/mild' compared with those without the respective condition. Pain is highly prevalent in individuals with SCI living in Switzerland. Considered at risk for chronic pain are women, older individuals and individuals with financial hardship and specific secondary health conditions. Longitudinal studies are necessary to identify predictors for the development of pain and its chronification.

No evidence of association between HIV-1 and malaria in populations with low HIV-1 prevalence.

Full Text Available The geographic overlap between HIV-1 and malaria has generated much interest in their potential interactions. A variety of studies have evidenced a complex HIV-malaria interaction within individuals and populations that may have dramatic effects, but the causes and implications of this co-infection at the population level are still unclear. In a previous publication, we showed that the prevalence of malaria caused by the parasite Plasmodium falciparum is associated with HIV infection in eastern sub-Saharan Africa. To complement our knowledge of the HIV-malaria co-infection, the objective of this work was to assess the relationship between malaria and HIV prevalence in the western region of sub-Saharan Africa.Population-based cross-sectional data were obtained from the HIV/AIDS Demographic and Health Surveys conducted in Burkina Faso, Ghana, Guinea, Mali, Liberia and Cameroon, and the malaria atlas project. Using generalized linear mixed models, we assessed the relationship between HIV-1 and Plasmodium falciparum parasite rate (PfPR adjusting for important socio-economic and biological cofactors. We found no evidence that individuals living in areas with stable malaria transmission (PfPR>0.46 have higher odds of being HIV-positive than individuals who live in areas with PfPR≤0.46 in western sub-Saharan Africa (estimated odds ratio 1.14, 95% confidence interval 0.86-1.50. In contrast, the results suggested that PfPR was associated with being infected with HIV in Cameroon (estimated odds ratio 1.56, 95% confidence interval 1.23-2.00.Contrary to our previous research on eastern sub-Saharan Africa, this study did not identify an association between PfPR and infection with HIV in western sub-Saharan Africa, which suggests that malaria might not play an important role in the spread of HIV in populations where the HIV prevalence is low. Our work highlights the importance of understanding the epidemiologic effect of co-infection and the relevant

The effective neutron-proton interaction V(np) in the rare earth odd-odd deformed nuclei is studied. The parameters of the effective interaction are determined from least square fits of calculated matrix elements compared to the ones extracted from experiment. These fits show the existence of a long range repulsive component as well the importance of the even term of the tensor part of V(np). Some informations are obtained concerning the influence of the choice of the sample of experimental data, of the average field and finally, of the radial shape of the effective interaction. Some predictions are made concerning as yet unconfirmed V(np) matrix elements [fr

The purpose of the current study is to examine the dietary patterns in a diverse cohort of individuals and to see if the identified dietary patterns predict the prevalence of adenoma in a cross-sectional study. Factor analysis was used to derive both sex- and population subgroup-specific dietary patterns among participants in the screening arm of the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. Logistic regression was used to assess associations between identified factor scores and colorectal adenoma (CRA) in sex-specific subgroups. Three diet patterns were observed in this cohort: 'Fruits and vegetables', 'Western' and 'Sweet and salty'. Foods that loaded on each factor were similar between the racial subgroups. In men, being in the highest quintile of 'Western' dietary scores was associated with higher odds of any (adjusted odds ratio (aOR) = 1.21; 95% confidence interval (CI) = 1.03-1.42), advanced (aOR = 1.32; 95% CI = 1.07-1.63) or multiple (>1; aOR = 1.51; 95% CI = 1.17-1.94) adenoma, compared to those in the lowest quintile. These results were most notably seen in Caucasian men. In women, having a 'Fruits and vegetable' score in the highest quintile was associated with lower odds of multiple adenoma (>1; aOR = 0.53; 95% CI = 0.28-1.00). Of the three dietary factors, the 'Western' diet pattern was most strongly associated with prevalent CRA in Caucasian men. Further research is needed to examine the association between dietary factor scores and adenomas in the proximal colon, where there are larger racial disparities in prevalence. © 2017 Dietitians Association of Australia.

The core-quasiparticle model for odd-odd nuclei and applications to candidates for gamma-ray lasers

International Nuclear Information System (INIS)

Strottman, D.D.

1988-01-01

A reliable estimate of the properties of isomers that may be viable candidates for a gamma-ray laser requires the use of the most accurate save functions possible. The majority of models that have been used to estimate the properties of isomers are applicable to only selected regions of the nuclear mass table. In particular, the Bohr-Mottelson model of odd-A and odd-odd nuclei will fail if the even-even core is not strongly deformed or if the deformations are changing strongly as a function of mass. This paper reports how the problem is overcome in a new core- quasiparticle model for odd-odd nuclei. The model introduces the pairing interaction ab initio; the odd-A states are mixtures of particle and hole states. The core may be soft towards deformation or axial asymmetry and may change rapidly as a function of mass. Thus, the model is ideally suited for application to the region of transitional nuclei such as the Te, La, and Os regions

The secondary sex ratio is the ratio of male to female live births and historically has ranged from 102 to 106 males to 100 females. Temporal declines have been reported in many countries prompting authors to hypothesize an environmental etiology. Blood specimens were obtained from 99 women aged 24-34 prior to attempting pregnancy and quantified for 76 polychlorinated biphenyl (PCB) congeners using dual column gas chromatography with electron capture detection. Women were prospectively followed until pregnancy or 12 cycles of trying. The odds of a male birth for three PCB groupings (total, estrogenic, anti-estrogenic) controlling for maternal characteristics were estimated using logistic regression. Among the 50 women with live births and PCB data, 26 female and 24 male infants were born (ratio 0.92). After adjusting for age and body mass index, odds of a male birth were elevated among women in the second (OR=1.29) and third (OR=1.48) tertiles of estrogenic PCBs; odds (OR=0.70) were reduced among women in the highest tertile of anti-estrogenic PCBs. All confidence intervals included one. The direction of the odds ratios in this preliminary study varied by PCB groupings, supporting the need to study specific PCB patterns when assessing environmental influences on the secondary sex ratio

The cumulative effect of core lifestyle behaviours on the prevalence of hypertension and dyslipidemia.

BACKGROUND: Most cardiovascular disease (CVD) occurs in the presence of traditional risk factors, including hypertension and dyslipidemia, and these in turn are influenced by behavioural factors such as diet and lifestyle. Previous research has identified a group at low risk of CVD based on a cluster of inter-related factors: body mass index (BMI) < 25 Kg\\/m2, moderate exercise, alcohol intake, non-smoking and a favourable dietary pattern. The objective of this study was to determine whether these factors are associated with a reduced prevalence of hypertension and dyslipidemia in an Irish adult population. METHODS: The study was a cross-sectional survey of 1018 men and women sampled from 17 general practices. Participants completed health, lifestyle and food frequency questionnaires and provided fasting blood samples for analysis of glucose and insulin. We defined a low risk group based on the following protective factors: BMI <25 kg\\/m2; waist-hip ratio (WHR) <0.85 for women and <0.90 for men; never smoking status; participants with medium to high levels of physical activity; light alcohol consumption (3.5-7 units of alcohol\\/week) and a "prudent" diet. Dietary patterns were assessed by cluster analysis. RESULTS: We found strong significant inverse associations between the number of protective factors and systolic blood pressure, diastolic blood pressure and dyslipidemia. The prevalence odds ratio of hypertension in persons with 1, 2, 3, > or = 4 protective factors relative to those with none, were 1.0, 0.76, 0.68 and 0.34 (trend p < 0.01). The prevalence odds ratio of dyslipidemia in persons with 1, 2, 3, > or = 4 protective factors relative to those with none were 0.83, 0.98, 0.49 and 0.24 (trend p = 0.001). CONCLUSION: Our findings of a strong inverse association between low risk behaviours and two of the traditional risk factors for CVD highlight the importance of \\'the causes of the causes\\' and the potential for behaviour modification in CVD prevention

Metabolic syndrome is associated with long-term morbidity and mortality after adult liver transplantation (LT). Whether pediatric LT recipients have a higher prevalence of metabolic syndrome remains controversial. In a cross-sectional study, we evaluated pediatric LT recipients aged 8-30 years using National Health and Nutrition Examination Survey (NHANES) protocols. LT recipients were matched by gender, race/ethnicity, and age with controls from NHANES. Pediatric LT recipients (n = 83), after adjusting for overweight/obesity and glucocorticoid use, had increased prevalence of prehypertension and hypertension, impaired glucose tolerance (IGT; 2-h glucose after oral glucose tolerance test ≥140 mg/dL), and low high-density lipoprotein compared to matched NHANES controls (n = 235) despite a lower prevalence of overweight/obesity. Among LT recipients, the adjusted odds of IGT doubled for every 7.5 years taking calcineurin inhibitors (odds ratio = 2.10, 95% confidence interval 1.06-4.17 per 7.5 years taking calcineurin inhibitors, p = 0.03). Among all subjects with IGT, LT recipients had a lower prevalence of overweight/obesity and less insulin resistance (homeostatic model assessment of insulin resistance) than did controls with IGT. Among normal weight subjects, LT recipients were significantly more likely than controls to have prehypertension/hypertension, IGT, low high-density lipoprotein, and metabolic syndrome. Pediatric LT recipients have unique metabolic syndrome profiles and risk factors and will require tailored screening and management protocols. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

Per current guidelines, patients with a first-degree relative (FDR) with colorectal cancer (CRC) should get screened at least at age 40. Data about the prevalence of adenomas and advanced adenomas (AAs) in these patients are lacking. To examine the prevalence of adenomas and AAs in 40- to 49-year-old individuals undergoing screening colonoscopy for family history of CRC. Retrospective chart review. Asymptomatic patients 40 to 49 years of age undergoing their first screening colonoscopy at the University of Michigan during the period 1999 to 2009 because of an FDR with CRC. Prevalence of adenomas (any size), AAs, and risk factors associated with adenomas. Among 640 study patients, the prevalence of adenomas (any size) was 15.4% and 3.3% for AAs. Adenoma prevalence was lower if the FDR with CRC was younger than 60 years of age versus an FDR with CRC older than 60 years of age (12.4% vs 19%, P = .034). Male sex (odds ratio 2.6; 95% CI, 1.06-4.4) and advancing age (odds ratio 1.16; 95% CI, 1.03-1.31) were associated with adenomas. Limited data on risk factor exposure and insufficient sample size to assess risk factors for AAs. Among 40- to 49-year-old patients undergoing screening colonoscopy because of an FDR with CRC, the prevalence of adenomas and AAs is low. Further research should determine whether these individuals have a higher prevalence of adenomas compared with average-risk individuals.

Transition strengths of Gamow-Teller decay of T{sub z} = {+-}1 nuclei to N = Z odd-odd nuclei have been calculated in a two-nucleon approximation for spherical and deformed nuclei. The results obtained for the latter are quite close to the values obtained by full-space shell-model calculations and to the experiment.

Whether night-shift work is a risk factor for gastroesophageal reflux disease is controversial. The aim of this study was to investigate the association between night-shift work and other factors, and erosive esophagitis. A cross-sectional study with 6040 male shipyard workers was performed. Esophagogastroduodenoscopic examination and a survey about night-shift work status, lifestyle, medical history, educational status, and marital status were conducted in all workers. The odds ratios of erosive esophagitis according to night-shift work status were calculated by using the logistic regression model. The prevalence of erosive esophagitis increased in the night-shift workers [odds ratio, 95 % confidence interval: 1.41 (1.03-1.94)]. According to multiple logistic regression models, night-shift work, obesity, smoking, and alcohol consumption of ≥140 g/week were significant risk factors for erosive esophagitis. By contrast, Helicobacter pylori infection was negatively associated with erosive esophagitis. Night-shift work is suggested to be a risk factor for erosive esophagitis. Avoidance of night-shift work and lifestyle modification should be considered for prevention and management of gastroesophageal reflux disease.

The expression for magnetic moments for the states comprising ground state configurations of odd-odd nuclei has been simplified by excluding mixing of other nucleonic configurations. This is contrary to Sharma's and Davidson's results which had been obtained by diagonalizing state matrices for a set of parameters using Davidov and Filippov's non-axial rotor model. According to the relative directions of spins of unpaired odd nucleons, the nuclei have been classified under four categories-an exercise not attempted till now. The calculations have been done with various quenching factors depending upon the relative spin orientations of odd nucleons. For most of the nuclei, the results show considerable improvement over those of Gallagher and Moszkowski and of Sharma.

Prevalence of traumatic brain injury in juvenile offenders: a meta-analysis.

Studies of traumatic brain injury (TBI) among adult populations demonstrate that such injuries can lead to aggressive behaviors. Related findings suggest that incarcerated individuals have high rates of brain injuries. Such studies suggest that traumatic brain injury may be related to the etiology and recidivism of criminal behavior. Relatively few studies have examined the prevalence of TBI using a delinquent juvenile sample. In order to assess the relationship between TBI and juvenile offender status, the current study used meta-analytic techniques to examine the odds of having a TBI among juvenile offenders. Across 9 studies, we found that approximately 30% of juvenile offenders have sustained a previous brain injury. Across 5 studies that used a control group, a calculated summary odds ratio of 3.37 suggests that juvenile offenders are significantly more likely to have a TBI compared to controls. Results suggest that the rate of TBIs within the juvenile offender population is significant and that there may be a relationship between TBIs and juvenile criminal behavior.

The Trend Odds Model for Ordinal Data‡

Capuano, Ana W.; Dawson, Jeffrey D.

2013-01-01

Ordinal data appear in a wide variety of scientific fields. These data are often analyzed using ordinal logistic regression models that assume proportional odds. When this assumption is not met, it may be possible to capture the lack of proportionality using a constrained structural relationship between the odds and the cut-points of the ordinal values (Peterson and Harrell, 1990). We consider a trend odds version of this constrained model, where the odds parameter increases or decreases in a monotonic manner across the cut-points. We demonstrate algebraically and graphically how this model is related to latent logistic, normal, and exponential distributions. In particular, we find that scale changes in these potential latent distributions are consistent with the trend odds assumption, with the logistic and exponential distributions having odds that increase in a linear or nearly linear fashion. We show how to fit this model using SAS Proc Nlmixed, and perform simulations under proportional odds and trend odds processes. We find that the added complexity of the trend odds model gives improved power over the proportional odds model when there are moderate to severe departures from proportionality. A hypothetical dataset is used to illustrate the interpretation of the trend odds model, and we apply this model to a Swine Influenza example where the proportional odds assumption appears to be violated.

Anemia is a frequent comorbidity in patients with heart failure. However, the incidence of anemia in patients with heart failure varies widely, and there is limited evidence on the association between anemia and rehospitalization and on the health consequences of anemia in patients with heart failure. We aimed to identify the prevalence of anemia and its influence on hospital readmissions and emergency department visits in outpatients with heart failure. This cross-sectional study included 284 patients with heart failure diagnosed at outpatient cardiology clinics at a tertiary care university hospital in Cheonan, South Korea. We obtained socio-demographic and clinical information, including frequency of readmissions and emergency department visits, using face-to-face interviews and medical record reviews. The prevalence of anemia, defined based on World Health Organization guidelines, was 39.1% among patients with heart failure. Anemia was significantly more prevalent among patients with one or more re-admissions or emergency department visits compared with patients with no history of hospital re-admissions or emergency department visits (42.7% vs. 13.9% ( p = 0.001) and 55.1% vs. 34% ( p = 0.002) respectively). Anemia increased the risk of hospital readmission (odds ratio =8.04, 95% confidence interval, 2.19-29.54) and emergency department visit (odds ratio=2.37, 95% confidence interval, 1.22-4.60) in patients with heart failure. It is imperative that patients with heart failure presenting with anemia undergo appropriate nursing assessment and intervention. Future prospective studies targeting interventions to improve anemia are required to determine whether anemia influences readmission rates and emergency department visits.

The current study aimed at establishing the prevalence of impulse control disorders (ICDs) in patients with Parkinson disease (PD) and their association with demographic, drug-related, and disease-related characteristics. We performed a single-center cross-sectional study of 805 PD patients. Impulse control disorders were investigated with the Questionnaire for Impulsive Compulsive Disorders in Parkinson's Disease; also comorbid neuropsychiatric complications (dementia, delusions, visual hallucinations) were investigated with clinical interviews and ad hoc instruments (Parkinson Psychosis Questionnaire and Neuropsychiatry Inventory). Impulse control disorders were identified in 65 patients (prevalence, 8.1%), with pathological gambling and hypersexuality the most frequent. Impulse control disorders were present in 57 of 593 cognitively preserved patients (prevalence, 9.6%) and in 8 of 212 demented patients (prevalence, 3.8%). Impulse control disorders were significantly associated with dopamine agonists (odds ratio [OR], 5.50; 95% confidence interval [CI], 2.60-12.46; P Impulse control disorders frequency was similar for pramipexole and ropinirole (16.6% vs 12.5%; OR, 1.45; 95% CI, 0.79-2.74; P = 0.227). Additional variables associated with ICDs were male sex and younger age. These findings suggested that dopaminergic treatments in PD are associated with increased odds of having an ICD, but also other demographic and clinical variables are associated with ICDs, suggesting the multifactorial nature of the ICD phenomenon in PD.

Occupational voice disorders in Poland account for over 25% of all occupational diseases. The aim of the study was to assess the prevalence of voice problems in the general population of Polish teachers, and identify risk factors for developing voice pathology. The study group comprised 425 female full-time teachers (most of them primary and secondary school, age ranging from 23 to 61 years) and 83 non-teacher women (control) whose jobs did not involve vocal effort, matched for age to the study group. All participants were subjected to a survey using an extensive questionnaire, and to laryngological, phoniatric and videostroboscopic examinations. The overall lifetime vocal symptoms were more frequent in the teachers than in the non-teachers (69 vs. 36%), and in particular it related to permanent and recurrent hoarseness, and dryness in the throat. Mean number of the voice symptoms was 3.21 in teachers and 1.98 in controls (p teachers. Mean maximum phonation time was shorter in teachers than in the controls (14.3 vs. 15.9 s, p dysphonia (that is thought to predispose to such pathology) were found in 32.7% of teachers and 9.6% of control subjects. The probability of developing incomplete glottal closure (odds ratio 13.2x; 95% CI: 1.8-96.8) and hyperfunctional dysphonia (odds ratio 2.7; 95% CI: 1.14-6.44) were significantly higher in the teacher group versus non-teachers. A significant positive relationship was found in teachers between the prevalence of hyperfunctional dysphonia and strained phonation, neck muscle hypertension, instability of voice, self-assessed hyper-arousal, and lifetime vocal effort index (years of employment as a teacher x hours of professional activity/week). The prevalence of vocal nodules and incomplete glottal closure were correlated with incorrect phonation technique parameters, but not with psychological factors. No correlation was found with environmental variables, such as classroom temperature, humidity, airborne dust. The prevalence of

Current study was designed to investigate the effects of obstructive sleep apnea (OSA) combined dyslipidemia on the prevalence of atherosclerotic cardiovascular diseases (ASCVD). This was a cross-sectional study and subjects with documented dyslipidemia and without previous diagnosis of OSA were enrolled. Polysomnography was applied to evaluate apnea-hypopnea index (AHI). Based on AHI value, subjects were classified into four groups: without OSA, mild, moderate and severe OSA groups. Clinical characteristics and laboratory examination data were recorded. Relationship between AHI event and lipid profiles was analyzed, and logistic regression analysis was used to evaluate the effects of OSA combined dyslipidemia on ASCVD prevalence. Totally 248 subjects with dyslipidemia were enrolled. Compared to the other 3 groups, subjects with severe OSA were older, male predominant and had higher smoking rate. In addition, subjects with severe OSA had higher body mass index, waist-hip ratio, blood pressure, and higher rates of overweight and obesity. Serum levels of fasting plasma glucose, glycated hemoglobin, LDL-C and CRP were all significantly higher. ASCVD prevalence was considerably higher in subjects with severe OSA. AHI event in the severe OSA group was up to 35.4 ± 5.1 events per hour which was significantly higher than the other groups (P dyslipidemia plus no-OSA group (reference group), OSA enhanced ASCVD risk in subjects with dyslipidemia, regardless of OSA severity. After extensively adjusted for confounding variables, the odds of dyslipidemia plus mild-OSA was reduced to insignificance. While the effects of moderate- and severe-OSA on promoting ASCVD risk in subjects with dyslipidemia remained significant, with severe-OSA most prominent (odds ratio: 1.52, 95% confidence interval: 1.13-2.02). OSA combined dyslipidemia conferred additive adverse effects on cardiovascular system, with severe-OSA most prominent.

The course of conduct disorder (CD) is heterogeneous. Moffitt proposed the heuristic of life course persistent (LCP) and adolescence limited (AL) to differentiate etiologically distinct forms of antisocial behavior (AB), each with distinct predictors and consequences, although a few studies have assessed this demarcation within the context of CD. The objective of this study was to apply Moffitt's taxonomy in a nationally representative US sample to investigate the prevalence, predictors, and outcomes of LCP and AL CD. Data come from the Collaborative Psychiatric Epidemiology Studies, a set of population-based nationally representative cross-sectional surveys (N = 20,130). Predictors included harsh discipline, maternal and paternal closeness, poverty in childhood, history of learning disability, parental deviance, and nativity. Outcomes included substance use, employment status, education attainment, marital status, income level, and self-rated mental and physical health. The prevalence of LCP and AL CD was 0.5 and 4.6%, respectively, for females, and 1.9 and 5.1%, respectively, for males. Low childhood SES [Odds Ratio (OR) = 3.49], lack of maternal closeness (OR = 2.50), and history of harsh discipline (OR = 2.17) increased odds of LCP group membership. The LCP group had higher odds of developing substance use disorders (OR = 2.00) relative to AL. LCP CD is more strongly influenced by childhood environment and confers increased odds for substance use problems in adulthood relative to AL CD.

Full Text Available OBJECTIVE: Epidemiologic evidence on long working hour and diabetes has been conflicting. We examined the association between overtime work and prevalence of diabetes among Japanese workers. METHODS: The subjects were 40,861 employees (35,170 men and 5,691 women, aged 16 to 83 years, of 4 companies in Japan. Hours of overtime were assessed using self-reported questionnaires. Diabetes was defined as a fasting plasma glucose ≥126 mg/dl (7.0 mmol/l, hemoglobin A1c ≥6.5% (48 mmol/mol, or current use of anti-diabetic drug. Multiple logistic regression analysis was used to calculate odds ratio of diabetes for each category of overtime. RESULTS: After adjustment for age, sex, company, smoking, and BMI, there was a suggestion of U-shaped relationship between overtime work and prevalence of diabetes (P for quadratic trend = 0.07. Compared with those who worked <45 hours of overtime per month, the adjusted odds ratios (95% confidence interval of diabetes were 0.86 (0.77-0.94, 0.69 (0.53-0.89, and 1.03 (0.72-1.46 for those who worked 45-79, 80-99, and ≥100 hours of overtime per month, respectively. In one company (n = 33,807, where other potential confounders including shift work, job position, type of department, alcohol consumption, sleep duration, leisure time physical activity, and family history of diabetes was additionally adjusted for, similar result was obtained (P for quadratic trend = 0.05. CONCLUSIONS: Long hours of overtime work may not be associated with increased prevalence of diabetes among Japanese workers.

Acrolein is an air toxic and highly potent respiratory irritant. There is little epidemiology available, but US EPA estimates that outdoor acrolein is responsible for about 75 percent of non-cancer respiratory health effects attributable to air toxics in the United States, based on the Agency's 2005 NATA (National-Scale Air Toxics Assessment) and acrolein's comparatively potent inhalation reference concentration of 0.02 µg/m3. Assess the association between estimated outdoor acrolein exposure and asthma attack reported by a representative cross-sectional sample of the adult United States population. NATA 2005 chronic outdoor acrolein exposure estimates at the census tract were linked with residences oif adults (≥18 years old) in the NHIS (National Health Interview Survey) 2000-2009 (n = 271,348 subjects). A sample-weighted logistic regression model characterized the association between the prevalence of reporting at least one asthma attack in the 12 months prior to survey interview and quintiles of exposure to outdoor acrolein, controlling for potential confounders. In the highest quintile of outdoor acrolein exposure (0.05-0.46 µg/m3), there was a marginally significant increase in the asthma attack pOR (prevalence-odds ratio [95% CI]  = 1.08 [0.98∶1.19]) relative to the lowest quintile. The highest quintile was also associated with a marginally significant increase in prevalence-odds (1.13 [0.98∶1.29]) in a model limited to never smokers (n = 153,820). Chronic exposure to outdoor acrolein of 0.05-0.46 µg/m3 appears to increase the prevalence-odds of having at least one asthma attack in the previous year by 8 percent in a representative cross-sectional sample of the adult United States population.

Full Text Available BACKGROUND: Acrolein is an air toxic and highly potent respiratory irritant. There is little epidemiology available, but US EPA estimates that outdoor acrolein is responsible for about 75 percent of non-cancer respiratory health effects attributable to air toxics in the United States, based on the Agency's 2005 NATA (National-Scale Air Toxics Assessment and acrolein's comparatively potent inhalation reference concentration of 0.02 µg/m3. OBJECTIVES: Assess the association between estimated outdoor acrolein exposure and asthma attack reported by a representative cross-sectional sample of the adult United States population. METHODS: NATA 2005 chronic outdoor acrolein exposure estimates at the census tract were linked with residences oif adults (≥18 years old in the NHIS (National Health Interview Survey 2000-2009 (n = 271,348 subjects. A sample-weighted logistic regression model characterized the association between the prevalence of reporting at least one asthma attack in the 12 months prior to survey interview and quintiles of exposure to outdoor acrolein, controlling for potential confounders. RESULTS: In the highest quintile of outdoor acrolein exposure (0.05-0.46 µg/m3, there was a marginally significant increase in the asthma attack pOR (prevalence-odds ratio [95% CI]  = 1.08 [0.98∶1.19] relative to the lowest quintile. The highest quintile was also associated with a marginally significant increase in prevalence-odds (1.13 [0.98∶1.29] in a model limited to never smokers (n = 153,820. CONCLUSIONS: Chronic exposure to outdoor acrolein of 0.05-0.46 µg/m3 appears to increase the prevalence-odds of having at least one asthma attack in the previous year by 8 percent in a representative cross-sectional sample of the adult United States population.

Island Puerto Rican (PR) youth experience disproportionately high asthma and obesity rates compared with other racial/ethnic groups on the U.S. mainland. Previous research has demonstrated associations of chronic disease with psychiatric disorders. We examined the relationship among anxiety/depressive disorders, asthma, and obesity in an epidemiologic community sample of youth. The sample (n = 656) was derived from the second wave of an island-wide probabilistic representative household sample of PR youth stratified and based on whether or not they had a diagnosis of asthma and/or depressive/anxiety disorder. For this study, we used the subpopulation ages 10-19 years. Asthma and obesity were significantly related to higher odds of depressive/anxiety disorders in youth. Obesity moderated the relationship between asthma attacks and depressive/anxiety disorders. The relationship between asthma attack and higher odds for depressive/anxiety disorders was only present in the non-obese group. Among the obese, females show a significant increase from 11% to 36% in the prevalence of anxiety/depressive disorders. Asthma and obesity were highly prevalent and a significant association was found between asthma attack and depressive/anxiety disorders. The effects of asthma and obesity were not additive; the prevalence for psychiatric disorder for those having both conditions did not increase above the prevalence associated having only one of the conditions. Future studies should consider including longitudinal designs and examine the extent to which important variables not included in this study, such as body image dissatisfaction (particularly among females), teasing, and discrimination may moderate the relationship among obesity and depressive and anxiety disorders in youth.

Full Text Available ABSTRACT BACKGROUND: Barrett’s esophagus a complication of gastroesophageal reflux disease (GERD is a precursor of esophageal adenocarcinoma. The incidence of esophageal adenocarcinoma has been increasing in most Western countries. Rio Grande do Sul (RS, the Southernmost state of Brazil has the highest rates of esophageal cancer with low prevalence of esophageal adenocarcinoma. OBJECTIVE: To investigate the prevalence of Barrett’s esophagus among patients underwent to upper gastrointestinal endoscopy in the last 5 years. METHODS: The records of patients underwent upper gastrointestinal endoscopy between 2011 and 2015 were analyzed. Demographic data, GERD symptoms, endoscopic findings, extension and histological diagnosis of columnar epithelia of the esophagus were recorded. Significance among the variables was accessed by chi-square test and Fisher’s exact test with 95% CI. RESULTS: A total of 5996 patients underwent to upper gastrointestinal endoscopy in the period were included. A total of 1769 (30% patients with GERD symptoms or esophagitis and 107 (1.8% with columnar lined esophagus were identified. Except for eight patients, the others with columnar lined esophagus had GERD symptoms or esophagitis. Barrett’s esophagus defined by the presence of intestinal metaplasia occurred in 47 patients; 20 (43% with segments over 3 cm and 27 (57% with segments shorter than 3 cm. The global prevalence of Barrett’s esophagus was 0.7% and in GERD patients 2.7%. The odds ratio for the occurrence of columnar lined esophagus in patients with GERD was 30 (95%CI=15.37-63.34. The odds ratio for the presence of intestinal metaplasia in long segments was 8 (95%CI=2.83-23.21. CONCLUSION: GERD patients had a risk 30-folds greater to present columnar lined esophagus than patients without GERD symptoms. Long segments of columnar lined esophagus, had a risk eight-folds higher to have Barrett’s esophagus than short segments. Barrett’s esophagus overall

Boson and fermion degrees of freedom in the orthosymplectic extension of the IVBM: Odd-odd nuclear spectra

2008-01-01

The dynamical symmetry group Sp(12, R) of the Interacting Vector Boson Model (IVBM) is extended to the orthosymplectic group OSp(2Ω/12, R) in order to incorporate fermion degrees of freedom. The structure of even-even nuclei is used as a core on which the collective excitations of the neighboring odd-mass and odd-odd nuclei are build on. Hence, the spectra of odd-mass and odd-odd nuclei arise as a result of the coupling of the fermion degrees of freedom, specified by the fermion sector SOF (2Ω) to the boson core, whose states belong to an Sp(12, R) irreducible representation. The orthosymplectic dynamical symmetry is applied for the simultaneous description of the spectra of some neighboring nuclei from rare earth region. The theoretical predictions for different low-lying collective bands with positive and negative parity are compared with the experiment. The obtained results reveal the applicability of the model and its boson-fermion extension.

To evaluate the estimation of prevalence ratio ( PR ) by using bayesian log-binomial regression model and its application, we estimated the PR of medical care-seeking prevalence to caregivers' recognition of risk signs of diarrhea in their infants by using bayesian log-binomial regression model in Openbugs software. The results showed that caregivers' recognition of infant' s risk signs of diarrhea was associated significantly with a 13% increase of medical care-seeking. Meanwhile, we compared the differences in PR 's point estimation and its interval estimation of medical care-seeking prevalence to caregivers' recognition of risk signs of diarrhea and convergence of three models (model 1: not adjusting for the covariates; model 2: adjusting for duration of caregivers' education, model 3: adjusting for distance between village and township and child month-age based on model 2) between bayesian log-binomial regression model and conventional log-binomial regression model. The results showed that all three bayesian log-binomial regression models were convergence and the estimated PRs were 1.130(95 %CI : 1.005-1.265), 1.128(95 %CI : 1.001-1.264) and 1.132(95 %CI : 1.004-1.267), respectively. Conventional log-binomial regression model 1 and model 2 were convergence and their PRs were 1.130(95 % CI : 1.055-1.206) and 1.126(95 % CI : 1.051-1.203), respectively, but the model 3 was misconvergence, so COPY method was used to estimate PR , which was 1.125 (95 %CI : 1.051-1.200). In addition, the point estimation and interval estimation of PRs from three bayesian log-binomial regression models differed slightly from those of PRs from conventional log-binomial regression model, but they had a good consistency in estimating PR . Therefore, bayesian log-binomial regression model can effectively estimate PR with less misconvergence and have more advantages in application compared with conventional log-binomial regression model.

This study compared prevalence of respiratory symptoms in three Indonesian villages and related this to air quality. We interviewed caregivers of 382 children, using the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire, and monitored air quality during the survey period. Respiratory symptom prevalence was highest in Kerinci (40.5%), followed by SP7 (33.3%) and Pelalawan (19.8%). Compared with Pelalawan, adjusted odds ratios were 3.17 (95% confidence interval, 1.43-7.07) for Kerinci, and 2.03 (1.04-3.96) for SP7. Ambient air quality levels were highest in Kerinci for PM10 and hydrocarbon (means: 102.9 microg/m3, 10.5 microg/m3), followed by SP7 (73.7 microg/m3, 6.3 microg/m3) and Pelalawan (26.1 microg/m3, 4.7 microg/m3). The higher prevalence of respiratory symptoms in Kerinci and SP7 could be the result of higher PM10 and hydrocarbon levels in these locations.

Factors influencing the increasing prevalence of overweight/obesity among children and adolescents in sub-Saharan Africa remain unclear. We assessed the prevalence and determinants of overweight and obesity and effects on cardio-metabolic profile in school learners in the Western Cape, South Africa. Cross-sectional data were collected from 7 to 18-year-old South African school learners attending 14 schools, randomly selected from 107 government schools in the areas. The learners were selected through stratified random sampling techniques. Logistic regressions were used to assess the determinants of overweight/obesity and its association with cardio-metabolic profile. Among the 1559 participants, the overall prevalence of overweight/obesity was 22.9%. Being a girl (Odds ratio 2.51, 95% CI: 1.92-3.29), or Black African (1.35, 1.04-.75) was associated with increased odds of being overweight/obese. The identified health consequences among the overweight/obese learners differed between the ethnic groups. Overweight/obese coloured (mixed ancestry) learners were more likely to have hypertension (3.27, 1.18-9.08), hypertriglyceridemia (1.94, 0.99-3.78) and low high-density lipoprotein cholesterol (HDL-C) (3.65, 2.33-5.72), overweight/obese Black African learners had higher odds for hypertension (3.62, 1.31-10.04) and low HDL-C (1.56, 1.01-2.40) and overweight/obese White learners were prone to low HDL-C (5.04, 1.35-18.80). Overweight/obesity is highly prevalent among school learners in Western Cape (South Africa), with being female or Black African increasing the odds. That overweight/obesity is also associated with adverse cardio-metabolic risk profile aggravates the problem and suggests worse cardiovascular outcomes in South African young adults in the future.

Objective To document the prevalence of overweight, obesity and thinness in 9–10 year old children in Mauritius. Methods 412 boys and 429 girls aged 9–10 years from 23 primary schools were selected using stratified cluster random sampling. All data was cross-sectional and collected via anthropometry and self-administered questionnaire. Outcome measures were BMI (kg/m2), prevalence of overweight, obesity (International Obesity Task Force definitions) and thinness (low BMI for age). Linear and logistic regression analyses, accounting for clustering at the school level, were used to assess associations between gender, ethnicity, school location, and school's academic performance (average) to each outcome measure. Results The distribution of BMI was marginally skewed with a more pronounced positive tail in the girls. Median BMI was 15.6 kg/m2 in boys and 15.4 kg/m2 in girls, respectively. In boys, prevalence of overweight was 15.8% (95% CI: 12.6, 19.6), prevalence of obesity 4.9% (95% CI: 3.2, 7.4) and prevalence of thinness 12.4% (95% CI: 9.5, 15.9). Among girls, 18.9% (95% CI: 15.5, 22.9) were overweight, 5.1% (95% CI: 3.4, 7.7) were obese and 13.1% (95% CI: 10.2, 16.6) were thin. Urban children had a slightly higher mean BMI than rural children (0.5 kg/m2, 95% CI: 0.01, 1.00) and were nearly twice as likely to be obese (6.7% vs. 4.0%; adjusted odds ratio 1.6; 95% CI: 0.9, 3.5). Creole children were less likely to be classified as thin compared to Indian children (adjusted odds ratio 0.3, 95% CI: 0.2, 0.6). Conclusion Mauritius is currently in the midst of nutritional transition with both a high prevalence of overweight and thinness in children aged 9–10 years. The coexistence of children representing opposite sides of the energy balance equation presents a unique challenge for policy and interventions. Further exploration is needed to understand the specific causes of the double burden of malnutrition and to make appropriate policy recommendations

To trial the collection of measurements to provide population-based prevalence of overweight and obesity in school children in western Sydney and examine the association between healthy weight and ethnicity and socio-economic status (SES) in a socio-economically and culturally diverse population. A cross-sectional population-based survey of 2341 children in Years 4 and 7 (mean ages 9 and 12 years, respectively) in 2007.   Nineteen percent of children were overweight and a further 6% were obese. The prevalence of combined overweight and obesity was similar for boys and girls (26% vs. 24%, P= 0.35). SES was significantly associated with the prevalence of unhealthy weight: the odds of being overweight or obese were 1.79 times (95% confidence interval (CI) 1.35 to 2.36) higher for children from the lowest quartile than for children from the highest quartile. Compared to children from an English speaking background, children from a non-English speaking background were significantly more likely to be overweight or obese (21% vs. 31%, P overweight and obesity was significantly higher for children from a Pacific Island (odds ratio (OR) 2.66, 95% CI 1.63 to 4.33), Middle Eastern (OR 1.63, 95% CI 1.22 to 2.17) or European (OR 1.67, 95% CI 1.12 to 2.49) background than for English speaking background children. Large jumps in the prevalence of overweight and obesity in children observed from the 1980s appear to be diminishing, with comparable prevalence reports in 2004 and 2007. Ethnicity and SES are each independently associated with the prevalence of unhealthy weight in children. © 2012 The Authors.

Quartetting in even-even and odd-odd N=Z nuclei

Sambataro, M.; Sandulescu, N.

2018-02-01

We report on a microscopic description of even-even N = Z nuclei in a formalism of quartets. Quartets are four-body correlated structures characterized by isospin T and angular momentum J. We show that the ground state correlations induced by a realistic shell model interaction can be well accounted for in terms of a restricted set of T = 0 low-J quartets, the J = 0 one playing by far a leading role among them. A conceptually similar description of odd-odd self-conjugate nuclei is given in terms of two distinct families of building blocks, one formed by the same T = 0 quartets employed for the even-even systems and the other by collective pairs with either T = 0 or T = 1. Some applications of this formalism are discussed for nuclei in the sd shell.

We have studied the Gamow-Teller (GT) transitions from N =Z +2 neighbors to N =Z odd-odd nuclei in the p -shell region by using isospin-projected and β γ -constraint antisymmetrized molecular dynamics combined with the generator coordinate method. The calculated GT transition strengths from 0+1 states to 1+0 states such as 6He(01+1 ) →6Li(11+0 ) , 10Be(01+1 ) →10B(11+0 ) , and 14C(01+1 ) →14N(12+0 ) exhaust more than 50% of the sum rule. These N =Z +2 initial states and N =Z odd-odd final states are found to dominantly have S =0 ,T =1 n n pairs and S =1 ,T =0 p n pairs, respectively. Based on the two-nucleon (N N ) pair picture, we can understand the concentration of the GT strengths as the spin-isospin-flip transition n n (S =0 ,T =1 )→p n (S =1 ,T =0 ) in L S coupling. The GT transition can be a good probe to identify the spin-isospin partner states with n n pairs and p n pairs of N =Z +2 and N =Z odd-odd nuclei, respectively.

Adult film work involves multiple sex partners, unprotected intercourse and frequent oral/rectal contact. Data on sexual networks and sexual behaviors of adult film performers (AFP) are limited. From August 2012 to May 2013, AFPs in Los Angeles, CA, seeking care at 2 clinics that provide sexually transmitted infections (STIs) testing to performers were offered urogenital, pharyngeal, and rectal chlamydia/gonorrhea testing. Participants were 18 years or older and performed in at least 1 adult film scene within the past year. A Web-based survey was used to collect sexual behavior information. A total of 360 AFPs were enrolled; 75% (n = 271) were women, and the median age was 25 years (interquartile range, 22-31 years). Most reported a main partner (73%), 23% reported non-film transactional partners, and only 6% reported always using condoms on-set. Overall, 24% (n = 86) tested positive for chlamydia or gonorrhea; 15% for chlamydia (n = 54) and 11% for gonorrhea (n = 41). Prevalence of chlamydia/gonorrhea varied by time as a performer (median, year 2 vs year 3; P = 0.06), and days of adult film-work in the past 30 days (median, 6 days vs 4 days; P = 0.02). In multivariable analyses, age (adjusted odds ratio, 0.90; 95% confidence interval, 0.85-0.96) and type of scene (adjusted odds ratio for double vaginal = 2.89; 95% confidence interval, 1.29-6.48) were associated with chlamydia/gonorrhea positivity. Adult film performers had a high prevalence of STIs and reported low levels of condom use in the context of most sexual partnerships. Targeted intervention strategies-both in and outside the workplace-are needed to limit the spread of STIs.

To perform a systematic review and meta-analysis of studies that compared the prevalence of anxiety symptoms in women with polycystic ovary syndrome (PCOS) and control women. Meta-analysis and systematic review. University practice. Cross-sectional studies comparing PCOS subjects and geographically matched clearly defined non-PCOS control subjects with data on age and body mass index (BMI). Anxiety screening tool. The primary analysis contrasted prevalence of anxiety. Cochrane Review Manager 5.0.24 software was used to construct forest plots comparing frequency of anxiety symptoms in case and control subjects. Of 613 screened articles, nine met our selection criteria for a systematic review and four were included in the meta-analysis. The prevalence of generalized anxiety symptoms was available in four studies and was significantly greater in PCOS subjects (42/206, 20.4%) compared to controls (8/204, 3.9%). The odds for anxiety symptoms were significantly greater in women with PCOS compared with control subjects (odds ratio 6.88, 95% confidence interval 2.5-18.9). The mean anxiety score was significantly increased in three of the remaining five studies. Other anxiety disorders, such as social phobia, panic attacks, and obsessive compulsive disorders, were assessed infrequently. Our systematic review suggests an increased odds of anxiety symptoms in women with PCOS, underscoring the importance of screening all women with PCOS for anxiety symptoms. Follow-up evaluation and treatment are essential, because generalized anxiety disorder is a chronic condition. Potential contributors for anxiety symptoms, such as hirsutism, obesity, and/or infertility may be specific to women with PCOS but need further investigation. Copyright © 2012.

Calculation of β-ray spectra. Odd-odd nuclei

1996-01-01

In order to study β-ray of atomic nucleus, it is natural to consider β-ray data fundamental and important. In a recent experiment, Rudstam measured β-ray spectra from short term nuclear fission product species in 1990. It is an important check point in theoretical study on β-ray to investigate if these experimental data can be reproduced by any theoretical calculation. As there are several spectrum studies of β-ray through decay heat for its various properties due to the general theory of the β-decay, little descriptions can be found. In even such studies, spectra under high excitation state of daughter species difficult to measure and apt to short experimental results were treated with combination spectra composed of experimental and calculated values such as substitution of a part of the general theory with calculated value. In this paper, the β spectra supposed by only the general theory was reported without using such data combination in order to confirm effectiveness of the theory. In particular, this report was described mainly on the results using recent modification of odd-odd nucleus species. (G.K.)

Controversy exists whether mood disorders, such as depression, are associated with Lyme borreliosis (LB). The study objective was to assess prevalence of depressive symptoms in subgroups of patients referred to a tertiary Lyme center, to investigate whether depressive symptoms can be used in clinical practice to discriminate for LB. This cohort study included adult patients who visited a tertiary Lyme center between January 2008 and December 2014. Prior to medical consultation, serum samples were taken and the Beck Depression Inventory II was completed to assess depressive symptoms. Lyme diagnosis was retrospectively extracted from the patient's medical record. Patients were classified based on clinical LB and serology results. Prevalence of moderate/severe depressive symptoms was calculated. Using logistic regression, odds ratios with 95% confidence intervals (CIs) were calculated for moderate/severe depressive symptoms. In total, 1454 patients were included. Prevalence of moderate/severe depressive symptoms was lowest in patients with no clinical LB and positive serology (15.3%), higher in patients with clinical LB with positive and negative serology (19.3% and 20.9% respectively), and highest in patients with no clinical LB and negative serology (29.3%). The odds ratio for moderate/severe depressive symptoms in patients with LB and positive serology was 0.71 (95% CI, .50-1.03) compared to patients with no LB and negative serology. The prevalence of depressive symptoms was similar in patients with LB compared to patients with no evidence of infection. This suggests that depressive symptoms cannot be used to discriminate for LB in a tertiary Lyme center. © The Author 2017.

Full Text Available Abstract Objective To describe current prevalence of obesity and related non-communicable diseases (NCDs in expatriates living in the United Arab Emirates (UAE. Methods We used data from the cross-sectional UAE National Diabetes and Lifestyle Study (UAEDIAB, which surveyed adult expatriates living in the UAE for at least 4 years. We report crude prevalence of overweight and obesity, indicated by gender and ethnicity-specific body mass index (BMI, waist circumference (WC and waist-to-hip ratio (WHR cut-offs, by lifestyle and biomedical characteristics, as well as age and sex-adjusted odds ratios. Results Out of a total of 3064 recruited expatriates (response rate 68%, 2724 had completed all stages of the UAEDIAB study. Expatriates were; 81% men, mean age 38 years (range 18–80, 71% South East Asians, and 36% university graduates. In this sample, the prevalence of overweight and obesity, by BMI, were 43.0 and 32.3%, respectively. 52.4 and 56.5% of participants were at a substantially increased risk according to WC and WHR, respectively. The prevalence of diabetes, hypertension and hypercholesterolemia were 15.5, 31.8, and 51.7%, respectively, with the prevalence of each being higher in those with obesity. Conclusion Prevalence of obesity and associated NCDs are extremely high in UAE expatriates. Without comprehensive prevention and management, levels of disease will continue to increase and productivity will fall.

To examine the prevalence and associations with the metabolic syndrome of albuminuria among Australian Aboriginal people. Early-morning urine specimens were collected as part of community-based risk factor surveys assessing the prevalence of diabetes and cardiovascular disease in eight remote communities, with a sample size of 1,075 people. Microalbuminuria was defined as urinary albumin : creatinine ratio 3.4-33.9 mg/mmol, macroalbuminuria as albumin: creatinine ratio equal to or greater than 34 mg/mmol. There were high prevalences of microalbuminuria (men 22.2 %, women 26.9 %) and of macroalbuminuria (men 10.4%, women 13.5%). There were highly statistically significant linear associations of microalbuminuria and macroalbuminuria with increasing number of coexisting components of the metabolic syndrome (hypertension, glucose intolerance, dyslipidaemia, insulin resistance, abdominal obesity): among people with zero, one, two and three to five of these conditions, respectively, prevalence of microalbuminuria was 16%, 20%, 36% and 32% (p < 0.001); prevalence of macroalbuminuria was 2%, 6%, 12% and 32% (p < 0.001). There were independent associations of microalbuminuria with hypertension (odds ratio, 95% confidence interval = 2.36, 1.63-3.42) and diabetes (2.10, 1.28-3.45): macroalbuminuria was independently associated with hypertension (6.39, 3.93-10.4), diabetes (3.49, 1.93-6.28) and abdominal obesity (4.56, 2.40-8.64) and had a weaker association with insulin resistance (1.99, 1.12-3.54). Dyslipidaemia and impaired glucose tolerance were neither independently associated with microalbuminuria or macroalbuminuria, nor was insulin resistance or abdominal obesity independently associated with microalbuminuria. There was a strong clustering of albuminuria with components of the metabolic syndrome. Diabetes, hypertension and abdominal obesity are major contributors to high rates of albuminuria among Australian Aboriginal people.

The objectives of this study were to investigate the effect of different dietary ratios of forage and concentrate (F:C) on ruminal odd- and branched-chain fatty acids (OBCFAs) contents and to evaluate the relationships between OBCFA and ruminal fermentation parameters as well as bacterial populations tested by real-time PCR technique. The experimental design was a 3 × 3 Latin square. Three rumen-fistulated dry Holstein cows were fed three rations with different dietary F:C ratios (F:C; 30:70, 50:50 and 70:30). The rumen samples were collected every two hours (0600, 0800, 1000, 1200, 1400, 1600, 1800, 2000, 2200, 2400, 0200 and 0400 h) over three consecutive days in each sampling period. The results showed that rumen OBCFA profiles are significantly (p ruminal OBCFAs had strong relationships with ruminal fermentation parameters and bacterial populations. In particular, the iso-fatty acids had potential power to predict butyrate and isoacids metabolized in the rumen, whereas the fatty acids with 17 carbon atoms correlated with ruminal NH 3 -N content. The OBCFA contents have different relationships with fibrolytic and starch bacteria in the rumen. C17:0 and its isomers might be used to predict populations of fibrolytic bacteria.

deCastro, B. Rey

2014-01-01

Background Acrolein is an air toxic and highly potent respiratory irritant. There is little epidemiology available, but US EPA estimates that outdoor acrolein is responsible for about 75 percent of non-cancer respiratory health effects attributable to air toxics in the United States, based on the Agency's 2005 NATA (National-Scale Air Toxics Assessment) and acrolein's comparatively potent inhalation reference concentration of 0.02 µg/m3. Objectives Assess the association between estimated outdoor acrolein exposure and asthma attack reported by a representative cross-sectional sample of the adult United States population. Methods NATA 2005 chronic outdoor acrolein exposure estimates at the census tract were linked with residences oif adults (≥18 years old) in the NHIS (National Health Interview Survey) 2000 – 2009 (n = 271,348 subjects). A sample-weighted logistic regression model characterized the association between the prevalence of reporting at least one asthma attack in the 12 months prior to survey interview and quintiles of exposure to outdoor acrolein, controlling for potential confounders. Results In the highest quintile of outdoor acrolein exposure (0.05 – 0.46 µg/m3), there was a marginally significant increase in the asthma attack pOR (prevalence-odds ratio [95% CI]  = 1.08 [0.98∶1.19]) relative to the lowest quintile. The highest quintile was also associated with a marginally significant increase in prevalence-odds (1.13 [0.98∶1.29]) in a model limited to never smokers (n = 153,820). Conclusions Chronic exposure to outdoor acrolein of 0.05 – 0.46 µg/m3 appears to increase the prevalence-odds of having at least one asthma attack in the previous year by 8 percent in a representative cross-sectional sample of the adult United States population.

We investigated the association between smoke-free laws and asthma prevalence, symptoms, and severity among nonsmoking youth (aged 3-15 years). We examined data from the 1999-2006 National Health and Nutrition Examination Survey, a cross-sectional survey designed to monitor the health and nutritional status of the US population. Survey locations were dichotomized as having or not having at least 1 smoke-free workplace, restaurant, or bar law at the county or state level that covered the entire county population. Asthma prevalence was assessed as self-reported current asthma and as ever having asthma with current symptoms. Asthmatic symptoms included persistent wheeze, chronic night cough, and wheeze-medication use. We also examined asthma severity (asthma attack or emergency-department visit for asthma) and persistent ear infection. Smoke-free laws were not associated with current asthma but were significantly associated with lower odds of asthmatic symptoms (odds ratio [OR]: 0.67 [95% confidence interval (CI): 0.48-0.93]) among nonsmoking youth. The association between smoke-free laws and ever having asthma with current symptoms approached significance (OR: 0.74 [95% CI: 0.53-1.03]). Smoke-free laws were associated with lower odds of asthma attacks (OR: 0.66 [95% CI: 0.28-1.56]) and emergency-department visits for asthma (OR: 0.55 [95% CI: 0.27-1.13]), although these results were not statistically significant. Our results suggest that smoke-free laws reduce asthmatic symptoms, including persistent wheeze, chronic night cough, and wheeze-medication use in nonsmoking youth.

2004-01-01

The nature of signature inversion in the πg 9/2 νh 11/2 bands of odd-odd 98,102 Rh nuclei is studied. Calculations are performed by using a triaxial rotor plus two-quasiparticle model and are compared with the experimentally observed signature inversions. The calculations reproduce well the observations and suggest that, in these bands, the signature inversion can be interpreted mainly as a competition between the Coriolis and the proton-neutron residual interactions in low K space. The triaxiality applied in the Hamiltonian enlarges the amplitudes of high spin signature zigzags at small triaxial deformation and might push the signature inversion point to higher spin at large triaxial deformation

Objectives: To describe the characteristics and prevalence of non-syndromic orofacial clefting (NSOFC) and assess the effects of parental consanguinity on NSOFC phenotypes in the 3 main cities of Saudi Arabia. Methods: All infants (114,035) born at 3 referral centers in Riyadh, and 6 hospitals in Jeddah and Madinah between January 2010 and December 2011 were screened. The NSOFC cases (n=133) were identified and data was collected through clinical examination and records, and information on consanguinity through parent interviews. The diagnosis was confirmed by reviewing medical records and contacting the infants’ pediatricians. Control infants (n=233) matched for gender and born in the same hospitals during the same period, were selected. Results: The prevalence of NSOFC was 1.07/1000 births in Riyadh, and 1.17/1000 births overall; cleft lip (CL) was 0.47/1000 births, cleft lip and palate (CLP) was 0.42/1000 births, and cleft palate (CP) was 0.28/1000 births. Cleft palate was significantly associated with consanguinity (p=0.047, odds ratio: 2.5, 95% confidence interval: 1 to 6.46), particularly for first cousin marriages. Conclusion: The birth prevalence of NSOFC in Riyadh alone, and in the 3 main cities of Saudi Arabia were marginally lower than the mean global prevalence. While birth prevalence for CLP was comparable to global figures, the CL:CLP ratio was high, and only CP was significantly associated with consanguinity. PMID:26318465

Background: Nutritional rickets is a public health concern in developing countries despite tropical climates and a re-emerging issue in developed countries. In this study, we reviewed pediatric admission data from the Clinical Information Network (CIN) to help determine hospital and region based prevalence of rickets in three regions of Kenya (Central Kenya, Western Kenya and Nairobi County). We also examine the association of rickets with other diagnosis, such as malnutrition and pneumonia, and study the effect of rickets on regional hospital stays. Methods: We analyzed discharge records for children aged 1 month to 5 years from county (formerly district) hospitals in the CIN, with admissions from February 1 st 2014 to February 28 th 2015. The strength of the association between rickets and key demographic factors, as well as with malnutrition and pneumonia, was assessed using odds ratios. The Fisher exact test was used to test the significance of the estimated odd ratios. Kaplan-Meier curves were used to analyze length of hospital stays. Results: There was a marked difference in prevalence across the three regions, with Nairobi having the highest number of cases of rickets at a proportion of 4.01%, followed by Central Region at 0.92%. Out of 9756 admissions in the Western Region, there was only one diagnosis of rickets. Malnutrition was associated with rickets; this association varied regionally. Pneumonia was found to be associated with rickets in Central Kenya. Children diagnosed with rickets had longer hospital stays, even when cases of malnutrition and pneumonia were excluded in the analysis. Conclusion: There was marked regional variation in hospital based prevalence of rickets, but in some regions it is a common clinical diagnosis suggesting the need for targeted public health interventions. Factors such as maternal and child nutrition, urbanization and cultural practices might explain these differences. PMID:29062911

Little is known about the epidemiology of metabolic syndrome in urban areas of China. To estimate the prevalence of MetS and identify its cardiovascular-related factors in men and women, a representative sample of 15,477 urban adults aged 18-74 years in Northeast China was selected from 2009 to 2010. The diagnosis of metabolic syndrome was based on criteria set by the National Cholesterol Education Program/Adult Treatment Panel. The overall prevalence of metabolic syndrome was 27.4% (men 27.9% and women 26.8%). Multivariable logistic regression analysis revealed that a higher education level and a higher family income were associated with a higher prevalence of metabolic syndrome in men, but associated with lower prevalence of metabolic syndrome among women. Higher physical activity was associated with a decreased prevalence of metabolic syndrome in men (adjusted odds ratios (aORs) = 0.88, 95% confidence interval (CI): 0.79-0.99), but associated with an increased prevalence of metabolic syndrome in women (aOR = 1.14, 95% CI: 1.00-1.29). Compared with rice as the major staple food, cooked wheaten foods were associated with lower adjusted odds for metabolic syndrome both in men (aOR = 0.72, 95% CI: 0.58-0.90) and in women (aOR = 0.72, 95% CI: 0.56-0.92). In conclusion, metabolic syndrome is highly prevalent in urban areas of China, and there is heterogeneity by sex in the relationships between risk factors and metabolic syndrome prevalence. © The Author(s) 2015.

To examine potential racial differences in Mediterranean diet scores and whether these differences are associated with the prevalence of colorectal adenoma (CRA), a cross-sectional analysis of data from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial was performed. The authors hypothesize that people consuming a more Mediterranean-like diet have lower odds of CRA. Flexible sigmoidoscopy was used to determine the presence of colorectal adenoma. Mediterranean diet scores were calculated from food frequency questionnaire responses. Logistic regression was used to determine the association between Mediterranean diet scores and the odds of prevalent CRA, as well as the joint effects of race and diet. Asians, followed by blacks, had higher Mediterranean diet scores than whites. Generally, men with better Mediterranean diet scores (altMED) had lower odds of CRA, but black and Asian men had even lower odds of prevalent CRA with better altMED diet scores than did white men with higher altMED diet scores. In this study population, all men had lower odds of prevalent CRA, but black and Asian men, who had higher (more favorable) altMED diet scores than whites, had even lower odds of prevalent CRA compared with white men. An altMED diet prescription may be especially beneficial for certain subpopulations who may be at higher risk of CRA. Copyright © 2017 Elsevier Inc. All rights reserved.

Linear odd Poisson bracket on Grassmann variables

A linear odd Poisson bracket (antibracket) realized solely in terms of Grassmann variables is suggested. It is revealed that the bracket, which corresponds to a semi-simple Lie group, has at once three Grassmann-odd nilpotent Δ-like differential operators of the first, the second and the third orders with respect to Grassmann derivatives, in contrast with the canonical odd Poisson bracket having the only Grassmann-odd nilpotent differential Δ-operator of the second order. It is shown that these Δ-like operators together with a Grassmann-odd nilpotent Casimir function of this bracket form a finite-dimensional Lie superalgebra.

The Mediterranean diet appears to be beneficial for several medical conditions, but data regarding osteoarthritis (OA) are not available. The aim of this study was to investigate if adherence to the Mediterranean diet is associated with a lower prevalence of OA of the knee in a large cohort from North America. 4358 community-dwelling participants (2527 females; mean age: 61.2 years) from the Osteoarthritis Initiative were included. Adherence to the Mediterranean diet was evaluated through a validated Mediterranean diet score (aMED) categorized into quartiles (Q). Knee OA was diagnosed both clinically and radiologically. The strength of the association between aMED (divided in quartiles) and knee OA was investigated through a logistic regression analysis and reported as odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for potential confounders. Participants with a higher adherence to Mediterranean diet had a significantly lower prevalence of knee OA compared to those with lower adherence (Q4: 25.2% vs. Q1: 33.8%; p Mediterranean diet, only higher use of cereals was associated with lower odds of having knee OA (OR: 0.76; 95%CI: 0.60-0.98; p = 0.03). Higher adherence to a Mediterranean diet is associated with lower prevalence of knee OA. This remained when adjusting for potential confounders.

To estimate prevalence and types of urinary incontinence (UI) among women living in the South Priaralye region, and to analyze risk factors associated with UI. The population-based study was conducted by nested-typological method. Analysis was carried out on the data of 1487 women collected by a standard ICIQ-SF questionnaire, an assessment tool for female urinary incontinence recommended by the European Association of Urology. The study showed that the prevalence of UI among women aged 18 years and older in the South Priaralye region was 27%. The predominant type of the disease was stress UI since in 44.8% of women, the uncontrolled urine loss occurred during exercise. In 16.1% of women urgent type UI was observed, and in 38.6% mixed type of UI was found. The most significant risk factors for UI were recurrent urinary tract infection (odds ratio (OR) of 5.9 (95% confidence interval (CI) 4.12-8.38), gynecological disease (OR 2.7 (95% CI 1.99-3.59), enuresis in childhood (OR 2.4 (95% CI 1.21-4.88), constipation (OR = 2.1 (95% CI 1.45-2.93) the number of births (OR = 1.2 (95% CI 1,05-1.28), and occupation, namely work involving physical strain (odds ratio of 1.2 (95% CI 1.04-1.43). In the area of the South Priaralye, more than a fourth of adult females were found to have a UI. Understanding the nature and risk factors for UI will allow planning the resources required to provide treatment and preventive measures in the future.

To determine the prevalence of body dysmorphic disorder (BDD) and muscle dysmorphia (MD) in enlisted U.S. military personnel; and secondarily, to determine supplement use and relationship with BDD and MD. A survey of advanced individual training of tri-service personnel at Fort Sam Houston, Texas, was performed combining the dysmorphia concern questionnaire, the MD symptom questionnaire, a supplement questionnaire, and demographic factors. Of the 1,320 service members approached, 1,150 (87.1%) completed the survey. The majority of participants were male, 62.8% (n = 722) and Army soldiers 59.0% (n = 679). The prevalence rate of BDD was 13.0% in males and 21.7% in females. The prevalence of MD was 12.7% in males and 4.2% in females. There was a strong correlation between having BDD and using supplements to get thinner (odds ratio 5.1; 95% confidence interval 3.4-7.8; p dysmorphias in mental health providers, primary care providers, and commanders and justifies further military specific BDD and MD research.

Covariant Density Functionals: time-odd channel investigated

International Nuclear Information System (INIS)

Afanasjev, A. V.; Abusara, H.

2009-01-01

The description of exotic nuclear systems and phenomena requires a detailed understanding of all channels of density functional theories. The role of time-odd mean fields, their evidence in experiment, and an accurate description of these fields are subject of current interest. Recent studies advanced the understanding of these fields in energy density functional theories based on the Skyrme force [1,2]. Time-odd mean fields are related to nuclear magnetism in covariant density functional (CDF) theories [3]. They arise from space-like components of vector mesons and Lorentz invariance requires that their coupling strengths are identical to that of time-like components. There were only few limited efforts to understand the role of time-odd mean fields in covariant density functional theory [4,5]. For example, the microscopic role of nuclear magnetism and its impact on rotational properties of nuclei has been studied in Ref. [5]. It is known that time-odd mean fields modify the angular momentum content of the single-particle orbitals and thus the moments of inertia, effective alignments, alignment gains at the band crossings and other physical observables. We aim on more detailed and systematic understanding of the role of time-odd mean fields in covariant density functional theory. This investigation covers both rotating and non-rotating systems. It is shown that contrary to the Skyrme energy density functionals time-odd mean fields of CDF theory always provide additional binding in the systems with broken time-reversal symmetry (rotating nuclei, odd mass nuclei). This additional binding increases with spin and has its maximum exactly at the terminating state [6], where it can reach several MeV. The impact of time-odd mean fields on the properties of rotating systems has been studied in a systematic way (as a function of particle number and deformation) across the nuclear chart [7]. In addition, this contribution extends these studies to non-rotating systems such as

Peri-implantitis is an inflammatory disease affecting soft and hard tissues surrounding dental implants. As the global number of individuals that undergo restorative therapy through dental implants increases, peri-implantitis is considered as a major and growing problem in dentistry. A randomly selected sample of 588 patients who all had received implant-supported therapy 9 y earlier was clinically and radiographically examined. Prevalence of peri-implantitis was assessed and risk indicators were identified by multilevel regression analysis. Forty-five percent of all patients presented with peri-implantitis (bleeding on probing/suppuration and bone loss >0.5 mm). Moderate/severe peri-implantitis (bleeding on probing/suppuration and bone loss >2 mm) was diagnosed in 14.5%. Patients with periodontitis and with ≥4 implants, as well as implants of certain brands and prosthetic therapy delivered by general practitioners, exhibited higher odds ratios for moderate/severe peri-implantitis. Similarly, higher odds ratios were identified for implants installed in the mandible and with crown restoration margins positioned ≤1.5 mm from the crestal bone at baseline. It is suggested that peri-implantitis is a common condition and that several patient- and implant-related factors influence the risk for moderate/severe peri-implantitis (ClinicalTrials.gov NCT01825772). © International & American Associations for Dental Research 2015.

Full Text Available Introduction: Abortion in cattle is a major source of economic losses for the agriculture sector. It can be due to infectious or non-infectious factors. Among infectious factors, parasites, bacteria, viruses, and fungi can be involved. The present work investigated the prevalence of the main infectious agents of abortion in Algerian cattle. Material and Methods: Altogether 278 non-aborting and 82 aborting cows were analysed. Results: The prevalence ranged from 0% for Tritrichomonas foetus to 15% for Neospora caninum. Additionally, a case-control study was performed to find the association between the presence of the pathogens and the occurrence of abortion in cows. The odds ratios were significant for Neospora caninum, bovine herpes virus 4, BVD virus, Brucella abortus, Salmonella Dublin, Leptospira interrogans serovar Hardjo, and Coxiella burnetii. Conclusions: The pathogens enumerated here could be major causes of abortion among Algerian cattle.

To examine the trend of urban-rural disparity in obesity prevalence among Chinese children from 1985 to 2010. The data were from five cross-sectional surveys (1985, 1995, 2000, 2005, and 2010) of Chinese National Surveys on Students' Constitution and Health. Logistic regression was used to estimate the prevalence odds ratio (POR) of urban-rural areas for obesity prevalence in different surveys. The standardized prevalence of obesity in Chinese children increased rapidly from 0.1% in 1985 to 5.0% in 2010, and significant differences were found between two adjacent surveys in most of the age subgroups (Pobesity prevalence was significantly higher in urban than in rural children of all age subgroups at different survey points, the changing pace was faster in rural than in urban areas from 1995 to 2010. The PORs had increased in 1995 in most age subgroups and then began to decline in all age subgroups after 1995. The gradually decreasing urban-rural disparity suggests that the obesity prevalence in rural areas would contribute to a growing proportion of obese children. Therefore, rural children should be included in obesity prevention efforts even though obesity rates are still lower in rural than in urban areas. © 2014 The Obesity Society.

This study aims to examine the association between the ratio of dietary branched chain amino acids (BCAA) and risk of obesity among young northern Chinese adults. A total of 948 randomly recruited participants were asked to finish our internet-based dietary questionnaire for the Chinese (IDQC). Associations between dietary BCAA ratio and prevalence of overweight/obesity and abdominal obesity were analyzed. Furthermore, 90 subjects were randomly selected to explore the possible mechanism. Dietary BCAA ratio in obese participants was significantly lower than non-obese participants. We found negative correlations between the ratio of dietary BCAA and body mass index (BMI) (r = -0.197, p BCAA ratio for overweight/obesity were 0.508 (0.265-0.972) and 0.389 (0.193-0.783), respectively (all p BCAA ratio were 0.351 (0.145-0.845) and 0.376 (0.161-0.876), respectively (all p BCAA ratio was inversely associated with 2-h postprandial glucose (2 h-PG) and status of inflammation. In conclusion, a higher ratio of dietary BCAA is inversely associated with prevalence of obesity, postprandial glucose and status of inflammation in young northern Chinese adults.

Full Text Available Objective: Men – more than women - engage in unhealthy lifestyle practices that place them at greater risk of developing non-communicable disease. This paper aims to explore the prevalence, co-occurrence and clustering of four core lifestyle risk factors and examine the socio demographic variation of their distribution, among men living in two central London boroughs. Method: A stratified street survey was undertaken with N=859 men. Prevalence odds ratios calculated risk factor clustering and a multinomial logistic regression model examined the socio-demographic variation. Results: Over 72% of men presented with combinations of lifestyle risk factors. Physical inactivity combined with a lack of fruit and vegetables was the most common combination. Co-occurrence was more prominent for unemployed, widowed, divorced/separated and white British men. Clustering was evident for adherence and non-adherence to UK health recommendations. Conclusion: Men may benefit from targeted health interventions that address multiple – rather than single – health related behaviours.

In the very recent years the knowledge of the level structure at lower and higher energies in the fpg shell N=Z nuclei has renewed a growing interest due to major improvements in the theoretical techniques. Going away from closed shell, the shell model calculations rapidly exhaust computer capabilities and we must resort to the model observed on collective phenomena. The fpg odd-odd N = Z nuclei close to the doubly magic 56 Ni nucleus are good candidates to investigate the competition between collective and single-particle excitations. Here part of the results obtained from an exhaustive systematic study of the self conjugate doubly-odd nuclei with A > 62: 62 Ga and 66 As nuclei using the interacting - boson - fermion - fermion - model (IBFFM) is presented. The odd-odd nuclei are described in the framework of the IBFFM by coupling valence shell proton and neutron quasiparticles to even-even core described in the interacting - boson model. In the first step of the calculations the core parameters for 60 Zn and 64 Ge cores were fitted to the energies of their excited states. In the second step of calculations, we have adjusted the IBFM proton Hamiltonian to the low - lying levels of 63 Ga and 67 As nuclei and IBFM neutron Hamiltonian of low - lying levels of 61 Zn and 65 Ge nuclei involved in the cases of the structure of odd-odd 62 Ga and 66 As nuclei. We have finally calculated the level spectra and electromagnetic properties of above mentioned nuclei. The IBFFM positive - parity energy spectra are compared with experimental ones. The calculations show a reasonable agreement with experimental data and existing shell - model calculations. (authors)

Musculoskeletal disorders (MSD) are important health problems in working populations. The study aimed to determine the prevalence of MSD among school teachers from urban and rural areas in Chuquisaca, Bolivia. A cross-sectional study was conducted in 60 randomly selected schools. In total, 1062 teachers were invited to participate (response 58%). The Spanish version of the Standardized Nordic questionnaire was used assessing the 12-months and 7-days prevalence of MSD as well as the 12-months prevalence of work limiting pain. Prevalence were calculated for the different parts of the body; as summary measures, MSD in any part of the body and in ≥3 parts of the body were assessed. Crude and adjusted odds ratios with 95% confidence intervals were calculated using logistic regression models adjusting for age, sex, teaching level and school type. Prevalence of MSD in any part of the body was 86% during the last 12 months, 63% during the last 7 days and 15% for work limiting pain. MSD was most common in the neck (12-months prevalence 47%) and least common in the wrist/hands (26%). In the adjusted model, teachers working in rural areas presented significantly higher odds than teachers from urban schools for work-limiting pain during the last 12-months considering any part of the body (aOR 2.2; 95% CI 1.1-4.1), and for ≥3 parts of the body (aOR 3.7; 95% CI 1.3-10.6). The prevalence of MSD is high in School teachers, even more in teachers working in rural areas. It is needed to identify risk factors for MSD in teachers in order to propose appropriate strategies to control and reduce it.

Background A lot of empirical studies have been conducted to evaluate the prevalence of depression and anxiety among Chinese adults with cancer. We aimed to conduct a meta-analysis in order to evaluate the prevalence and odds ratios of depression and anxiety in Chinese adults with cancer compared with those without. Methods The three most comprehensive computerized Chinese academic databases-CNKI, Wangfang and Vip databases-were systematically screened through September 2012. PubMed and Web of Science (SCIE) were also searched from their inception until September 2012 without language restrictions, and an internet search was also used. Case–control studies assessing the prevalence of depression and anxiety among Chinese adults with cancer were analyzed. Study selection and appraisal were conducted independently by three authors. The non-weighted prevalence, pooled random-effects estimates of odds ratio (OR) and 95% confidence intervals (CI) were all calculated. Results Seventeen eligible studies with a total of 3497 subjects were included. The prevalence of depression and anxiety were significantly higher in adults with cancer compared with those without (Depression: 54.90% vs. 17.50%, OR = 7.85, 95% CI = 5.56-11.07, P = 0.000; Anxiety: 49.69% vs. 18.37%, OR = 6.46, 95% CI = 4.36-9.55, P = 0.000), the same situation was also observed in subgroup of control groups, assessment methods and cancer types. Although no difference of depression was observed in studies utilizing clinical diagnosis compared with self-report, the OR of anxiety in adults with cancer compared with those without was higher in studies utilizing clinical diagnosis (OR = 8.42, 95% CI = 4.83-14.70) than self-reports (OR = 5.83, 95% CI = 3.64-9.34). The ORs of depression and anxiety in cancer patients compared with disease group (Depression: OR = 6.03, 95% CI = 4.23-8.61; Anxiety: OR = 4.40, 95% CI = 3.05-6.36) were lower than in those

To examine the prevalence and structural correlates of gender based violence against female sex workers in an environment of criminalised prostitution. Prospective observational study. Vancouver, Canada during 2006-8. Female sex workers 14 years of age or older (inclusive of transgender women) who used illicit drugs (excluding marijuana) and engaged in street level sex work. Self reported gender based violence. Of 267 female sex workers invited to participate, 251 women returned to the study office and consented to participate (response rate of 94%). Analyses were based on 237 female sex workers who completed a baseline visit and at least one follow-up visit. Of these 237 female sex workers, 57% experienced gender based violence over an 18 month follow-up period. In multivariate models adjusted for individual and interpersonal risk practices, the following structural factors were independently correlated with violence against female sex workers: homelessness (adjusted odds ratio for physical violence (aOR(physicalviolence)) 2.14, 95% confidence interval 1.34 to 3.43; adjusted odds ratio for rape (aOR(rape)) 1.73, 1.09 to 3.12); inability to access drug treatment (adjusted odds ratio for client violence (aOR(clientviolence)) 2.13, 1.26 to 3.62; aOR(physicalviolence) 1.96, 1.03 to 3.43); servicing clients in cars or public spaces (aOR(clientviolence) 1.50, 1.08 to 2.57); prior assault by police (aOR(clientviolence) 3.45, 1.98 to 6.02; aOR(rape) 2.61, 1.32 to 5.16); confiscation of drug use paraphernalia by police without arrest (aOR(physicalviolence) 1.50, 1.02 to 2.41); and moving working areas away from main streets owing to policing (aOR(clientviolence) 2.13, 1.26 to 3.62). Our results demonstrate an alarming prevalence of gender based violence against female sex workers. The structural factors of criminalisation, homelessness, and poor availability of drug treatment independently correlated with gender based violence against street based female sex workers. Socio

Full Text Available Abstract Background The purpose of this study was to determine the prevalence of high blood pressure (HBP and associated risk factors in school children 8 to 13 years of age. Methods Elementary school children (n = 1,066 were examined. Associations between HBP, body mass index (BMI, gender, ethnicity, and acanthosis nigricans (AN were investigated using a school based cross-sectional study. Blood pressure was measured and the 95th percentile was used to determine HBP. Comparisons between children with and without HBP were utilized. The crude and multiple logistic regression adjusted odds ratios were used as measures of association. Results Females, Hispanics, overweight children, and children with AN had an increased likelihood of HBP. Overweight children (BMI ≥ 85th percentile and those with AN were at least twice as likely to present with HBP after controlling for confounding factors. Conclusion Twenty one percent of school children had HBP, especially the prevalence was higher among the overweight and Hispanic group. The association identified here can be used as independent markers for increased likelihood of HBP in children.

Aims To examine trajectories of headache in relation to retirement and to clarify the role of work stress and stress-prone personality. Methods Headache prevalence during seven years before and after retirement was measured by annual questionnaires from GAZEL cohort comprising French national gas and electricity company employees (N=12,913). Odds ratios and 95% confidence intervals for headache during pre- peri- and post-retirement were calculated. The role of effect modifiers (work stress, type A or hostile personality) was tested by multiplicative interactions and synergy indices. Results 11%-13% reduction in headache prevalence was found during pre- and post-retirement, whereas decline was much steeper (46%) during the retirement transition. In absolute terms, the decline was greater among persons with high work stress or stress-prone personality than among other participants. Conclusions Retirement is associated with a decrease in headache prevalence, particularly among persons with high amount of work stress or proneness to overreact to stress. PMID:21220374

Environmental (i.e., meteorological and landscape) factors and management practices can affect the prevalence of foodborne pathogens in produce production environments. This study was conducted to determine the prevalence of Listeria monocytogenes, Listeria species (including L. monocytogenes), Salmonella, and Shiga toxin-producing Escherichia coli (STEC) in produce production environments and to identify environmental factors and management practices associated with their isolation. Ten produce farms in New York State were sampled during a 6-week period in 2010, and 124 georeferenced samples (80 terrestrial, 33 water, and 11 fecal) were collected. L. monocytogenes, Listeria spp., Salmonella, and STEC were detected in 16, 44, 4, and 5% of terrestrial samples, 30, 58, 12, and 3% of water samples, and 45, 45, 27, and 9% of fecal samples, respectively. Environmental factors and management practices were evaluated for their association with terrestrial samples positive for L. monocytogenes or other Listeria species by univariate logistic regression; analysis was not conducted for Salmonella or STEC because the number of samples positive for these pathogens was low. Although univariate analysis identified associations between isolation of L. monocytogenes or Listeria spp. from terrestrial samples and various water-related factors (e.g., proximity to wetlands and precipitation), multivariate analysis revealed that only irrigation within 3 days of sample collection was significantly associated with isolation of L. monocytogenes (odds ratio = 39) and Listeria spp. (odds ratio = 5) from terrestrial samples. These findings suggest that intervention at the irrigation level may reduce the risk of produce contamination.

In a community-dwelling elderly cohort (Korean Urban Rural Elderly), low peak jump power was associated with elevated odds of dysmobility syndrome and its components, independent of age and comorbidities. Jump power measurement improved discrimination of individuals with dysmobility syndrome when added to conventional risk factors. Dysmobility syndrome was proposed to encompass the risks affecting musculoskeletal outcomes. Jump power measurement is a safe, reproducible high-intensity test for physical function in elderly. However, the relationship between jump power and dysmobility syndrome remains unknown. A total of 1369 subjects (mean 71.6 years; women, 66%) were analyzed from a community-based cohort. Dysmobility syndrome was defined as the presence of ≥ 3 factors among falls in the preceding year, low lean mass, high fat mass, osteoporosis, low grip strength, and low timed get-up-and-go (TUG) performance. Subjects were grouped into tertiles of jump power relative to weight based on sex-stratified cutoffs (32.4 and 27.6 W/kg in men; 23.9 and 19.9 W/kg in women) or into the failed-to-jump group. The prevalence of dysmobility syndrome was 20% overall, increasing from the highest (T1) to lowest (T3) jump power tertile (1, 11, 15% in men; 11, 16, 39% in women) and the failed-to-jump group (39% in men; 48% in women). Low jump power or failed-to-jump was associated with elevated odds of dysmobility syndrome (T3 vs. T1, adjusted odds ratio [aOR] 4.35, p jump vs. T1, aOR 7.60, p Jump power modestly discriminated dysmobility syndrome (area under the curve [AUC], 0.71, p jump power was associated with elevated odds of dysmobility syndrome and its components, independent of age and comorbidities.

occupations (68.9%, CI 68.1, 69.7). A logistic regression model adjusted for socio-demographic composition indicated that, compared to nurses, the odds of being overweight or obese was statistically significantly lower for other healthcare professionals (Odds Ratio [OR] 0.45, CI 0.33, 0.61) and those in non-health related occupations (OR 0.78, CI 0.62, 0.97). Prevalence of overweight and obesity among Scottish nurses is worryingly high, and significantly higher than those in other healthcare professionals and non-health related occupations. High prevalence of overweight and obesity potentially harms nurses' own health and hampers the effectiveness of nurses' health promotion role. Interventions are therefore urgently required to address overweight and obesity among the Scottish nursing workforce. Copyright © 2015 Elsevier Ltd. All rights reserved.

A detailed low-energy level scheme of the odd-odd n-rich nucleus {sub 73}{sup 184}Ta{sub 111} is constructed using the well tested Two-Quasiparticle Rotor Model (TQRM) for calculating the bandhead energies of physically admissible 2qp configurations with the inclusion of residual n-p interaction contribution. The presently available data on this level scheme from {sup 184}Hf decay are shown to be in agreement with these calculations. Our analysis concludes that {sup 184}Hf (Q{sub β} = 1340(30) keV) decay admits of 7 additional (to the 3 presently reported) β -branches to {sup 184}Ta with J = 0 or 1 and 8 more physically admissible weak (1f{sup u}) β -branches populating J{sup π} = 2{sup -} levels in {sup 184}Ta. Further, a close examination of our level scheme clearly indicates the existence of a low-lying (E{sub x} = 260(40) keV) high-spin (J{sup π} = 10{sup -}) long-lived isomer in this nucleus. (orig.)

The low-lying states in the odd-odd and unstable isotopes In-106,In-108 have been Coulomb excited from the ground state and the first excited isomeric state at the REX-ISOLDE facility at CERN. With the additional data provided here the pi g(9/2)(-1) circle times nu d(5/2) and pi g(9/2)(-1) circle times nu g7/2 multiplets have been re-analyzed and are modified compared to previous results. The observed gamma-ray de-excitation patterns were interpreted within a shell model calculation based on a realistic effective interaction. The agreement between theory and experiment is satisfactory and the calculations reproduce the observed differences in the excitation pattern of the two isotopes. The calculations exclude a 6(+) ground state in In-106. This is in agreement with the conclusions drawn using other techniques. Furthermore, based on the experimental results, it is also concluded that the ordering of the isomeric and ground state in In-108 is inverted compared to the shell model prediction.

French farmers and their families constitute an informative population to study multiple sclerosis (MS) prevalence and related epidemiology. We carried out an ecological study to evaluate the association of MS prevalence and ultraviolet (UV) radiation, a candidate climatologic risk factor. Mean annual and winter (December-March) UVB irradiation values were systematically compared to MS prevalence rates in corresponding regions of France. UVB data were obtained from the solar radiation database (SoDa) service and prevalence rates from previously published data on 2,667 MS cases registered with the national farmer health insurance system, Mutualité Sociale Agricole (MSA). Pearson correlation was used to examine the relationship of annual and winter UVB values with MS prevalence. Male and female prevalence were also analyzed separately. Linear regression was used to test for interaction of annual and winter UVB with sex in predicting MS prevalence. There was a strong association between MS prevalence and annual mean UVB irradiation (r = -0.80, p role for gender-specific effects of UVB exposure.

We present a general theory of the proximity effect in junctions between unconventional superconductors and diffusive normal metals (DN) or ferromagnets (DF). We consider all possible symmetry classes in a superconductor allowed by the Pauli principle: even-frequency spin-singlet even-parity state, even-frequency spin-triplet odd-parity state, odd-frequency spin-triplet even-parity state and odd-frequency spin-singlet odd-parity state. For each of the above states, symmetry and spectral properties of the induced pair amplitude in the DN (DF) are determined. The cases of junctions with spin-singlet s- and d-wave superconductors and spin-triplet p-wave superconductors are adressed in detail. We discuss the interplay between the proximity effect and midgap Andreev bound states arising at interfaces in unconventional (d- or p-wave) junctions. The most striking property is the odd-frequency symmetry of the pairing amplitude induced in DN (DF) in contacts with p-wave superconductors. This leads to zero-energy singularity in the density of states and to anomalous screening of an external magnetic field. Peculiarities of Josephson effect in d- or p-wave junctions are discussed. Experiments are suggested to detect an order parameter symmetry using heterostructures with unconventional superconductors.

South Korea has an increasing prevalence of diabetes and a relatively high burden of tuberculosis. We aimed to determine the prevalence of diabetes in patients with active pulmonary tuberculosis (PTB) and examine the effect of diabetes on tuberculosis treatment outcomes. Data from patients ≥30 years diagnosed with and treated for PTB between January 2010 and December 2012 at Severance Hospital, a 2000-bed tertiary referral hospital in Seoul, South Korea, were analyzed and compared with data from a contemporaneous general population sample extracted from KNHANES V. Diabetes prevalence was 24.2% (252/1044) among patients with PTB and 11.6% (1700/14,655) among controls. Diabetes [odds ratios (OR) 2.56, 95% confidence interval (CI) 1.56-4.21, P Diabetes was the only factor associated with unsuccessful treatment outcomes (OR 1.67, 95% CI 1.03-2.70, P = 0.039). The prevalence of diabetes was markedly higher in patients with PTB than in a sample of the general South Korean population. Diabetes may delay sputum conversion and adversely affect treatment outcomes; detection and management of diabetes in patients with PTB is crucial.

Pleural effusion is frequent in intensive care unit patients, but its impact on the outcome of weaning remains unknown. In a prospective study performed in three intensive care units, pleural ultrasound was performed at the first spontaneous breathing trial to detect and quantify pleural effusion (small, moderate, and large). Weaning failure was defined by a failed spontaneous breathing trial and/or extubation requiring any form of ventilatory support within 48 h. The primary endpoint was the prevalence of pleural effusion according to weaning outcome. Pleural effusion was detected in 51 of 136 (37%) patients and was quantified as moderate to large in 18 (13%) patients. As compared to patients with no or small pleural effusion, their counterparts were more likely to have chronic renal failure (39 vs. 7%; P = 0.01), shock as the primary reason for admission (44 vs. 19%; P = 0.02), and a greater weight gain (+4 [0 to 7] kg vs. 0 [-1 to 5] kg; P = 0.02). The prevalence of pleural effusion was similar in weaning success and weaning failure patients (odds ratio, 1.23; 95% CI, 0.61 to 2.49; P = 0.56), as was the prevalence of moderate to large pleural effusion (odds ratio, 0.89; 95% CI, 0.33 to 2.41; P = 1.00). Duration of mechanical ventilation and intensive care unit length of stay were similar between patients with no or small pleural effusion and those with moderate to large pleural effusion. Significant pleural effusion was observed in 13% of patients at the time of liberation from mechanical ventilation and was not associated with an alteration of weaning outcome.

Anosognosia is a disorder that affects the clinical presentation of Alzheimer's disease (AD), increasing in frequency with the evolution of AD. The objective was to determine the prevalence of anosognosia and analyze the associated factors and predictors. Multicenter transversal and observational study of 345 AD patients. Anosognosia was assessed by Anosognosia Questionnaire-Dementia and the evolutionary stage with the Global Deterioration Scale (GDS). Tests used were Mini-Mental State Examination, Disability Assessment for Dementia and Neuropsychiatric Inventory to assess cognition, functional status and neuropsychiatric symptoms, respectively. We adjusted linear regression models to determine the associated variables and binary logistic regression (RLog) to identify predictors of anosognosia. The overall prevalence of anosognosia was 46.7% (95% confidence interval [95% CI] 41.3 to 52.1). The prevalence in stages was 28.4% (GDS 4), 64.6% (GDS 5) and 91.4% (GDS 6). The RLog identified as predictors older age (odds ratio [OR] 1.04; 95% CI 1.01-1.09), lower functional capacity (OR 0.96; 95% CI 0.93-0.98), lower cognitive level (OR 0.9; 95% CI 0.88-0.99), and greater apathy (OR 1.1; 95% CI 1.03-1.18), disinhibition (OR 1.2; 95% CI 1.09-1.50), irritability (OR 1.1; 95% CI 1.09-1.50) and motor disorders (OR 1.2; 95% CI 1.09-1.50). Anosognosia increases with further deterioration. In patients with a mild impairment, predictor variables were apathy, disinhibition and motor disorders. Copyright © 2013 Elsevier España, S.L.

Full Text Available Background. It has been observed that African American race is associated with a lower prevalence of atrial fibrillation (AF compared to Caucasian race. To better quantify the association between African American race and AF, we performed a meta-analysis of published studies among different patient populations which reported the presence of AF by race. Methods. A literature search was conducted using electronic databases between January 1999 and January 2011. The search was limited to published studies in English conducted in the United States, which clearly defined the presence of AF in African American and Caucasian subjects. A meta-analysis was performed with prevalence of AF as the primary endpoint. Results. In total, 10 studies involving 1,031,351 subjects were included. According to a random effects analysis, African American race was associated with a protective effect with regard to AF as compared to Caucasian race (odds ratio 0.51, 95% CI 0.44 to 0.59, <0.001. In subgroup analyses, African American race was significantly associated with a lower prevalence of AF in the general population, those hospitalized or greater than 60 years old, postcoronary artery bypass surgery patients, and subjects with heart failure. Conclusions. In a broad sweep of subjects in the general population and hospitalized patients, the prevalence of AF in African Americans is consistently lower than in Caucasians.

Physical inactivity surveillance informs policy and treatment options toward meeting the World Health Organization's (WHO) goal of a 10% reduction in its prevalence by 2025. We currently do not know the aggregate prevalence for Muslim-majority countries, many of which have extremely high rates of comorbidities associated with physical inactivity. Based on data for 163, 556 persons in 38 Muslim countries that were collected by the Global Physical Activity Questionnaire and the International Physical Activity Questionnaire, unweighted and weighted physical inactivity prevalence estimates were calculated. I used two-proportion Z tests to determine gender and ethnic differences within the sample and between the sample and 94 non-Muslim countries and odds ratios to determine the magnitude of significant differences. Total physical inactivity prevalence was 32.3% (95% CI: 31.9, 32.7). Prevalence among males and females was 28.8% and 35.5%, respectively. Prevalence among non-Arabs and Arabs was 28.6% and 43.7%, respectively. Females and Arabs were more likely physically inactive than their respective counterparts [OR = 1.36 (1.33, 1.39) and OR = 1.94 (1.90, 1.98)]. Muslim countries were more likely physically inactive [OR = 1.23 (1.22, 1.25)] than non-Muslim ones, which was primarily due to the influence of Arabs [OR = 2.01 (1.97, 2.04)], and in particular female Arabs [OR = 2.22 (2.17, 2.27)]. Physical inactivity prevalence in the Muslim world is higher than non-Muslim countries and the difference is primarily due to higher rates among Arabs.

Full Text Available Background: With the development of economy and urbanization, methods of child-feeding have significantly changed in China over the past three decades. However, little is known about breastfeeding in China since 2009. This study aims to update information on the prevalence of breastfeeding in China. Methods: Data were obtained from the first Health Service Household Interview Survey of Hunan Province, China. Of 24,282 respondents, 1659 were aged five years or younger. We ran multivariable logistic regression to examine the impact of urban/rural setting, gender, age and household income per capita on the use of breastfeeding. Results: A total of 79.4% of children aged 5 years or younger had been breastfed at some point and 44.9% been breastfed exclusively in the first 6 months of life. After controlling for setting urban/rural setting, gender and child age, children from households with average family income were more likely to be breastfed than those from households with the lowest family income (adjusted odds ratio: 2.28. Children from households with higher and the highest family income were less likely to be exclusively breastfed in the first 6 months of life compared to those from households with the lowest family income (adjusted odds ratio: 0.51 and 0.68, respectively. Conclusions: It is encouraging that the prevalence of exclusive breastfeeding for infants in the first 6 months of life in Hunan Province, China is approaching the goal of 50% proposed by the World Health Organization (WHO. Nevertheless, more efforts are needed to further promote exclusive breastfeeding in the first 6 months after birth.

Full Text Available Asthma is the commonest and most important chronic non-infectious disease in childhood and it has become more prevalent in recent years. There is a shortage of studies in relation to early childhood and so, as part of the INAIRCHILD project, this cross-sectional study aimed to assess the prevalence of asthma and its associated risk factors, namely demographic, environmental, psychosocial and clinical factors for infants and preschoolers living in Northern Portugal. Data concerning asthma prevalence were collected through questionnaires based on those from the International Study of Asthma and Allergies in Childhood (ISAAC-derived, the questionnaires were distributed to 1042 children attending the 17 nurseries involved in the INAIRCHILD project (10 in urban and suburban context, and 7 in rural context. The response rate was 48%. Prevalence of asthma based on symptomatology and odds ratio was calculated. Around 52% of the studied children presented at least one of the respiratory symptoms investigated (wheeze, dyspnea and cough in the absence of upper respiratory infections. The prevalence of asthma was 10.7%, comparable to the figures for Portuguese schoolchildren (6–7 years old reported by the national Directorate-General of Health, thus showing that an early diagnosis might be possible and helpful for the mitigation of childhood asthma. Environmental context (urban, suburban or rural, gender and family asthma history showed clear associations with asthma prevalence, namely non-rural location, male gender, and having an asthmatic parent were found to be risk factors.

The aims of this study were to examine trajectories of headache in relation to retirement and to clarify the role of work stress and stress-prone personality. Headache prevalence during the 7 years before and after retirement was measured by annual questionnaires from GAZEL cohort comprising French national gas and electricity company employees (n = 12,913). Odds ratios and 95% confidence intervals for headache during pre- peri- and post-retirement were calculated. The role of effect modifiers (work stress, type A or hostile personality) was tested by multiplicative interactions and synergy indices. An 11-13% reduction in headache prevalence was found during pre- and post-retirement, whereas decline was much steeper (46%) during the retirement transition. In absolute terms, the decline was greater among persons with high work stress or stress-prone personality than among other participants. Retirement is associated with a decrease in headache prevalence, particularly among persons with a high amount of work stress or proneness to over-react to stress.

In low- and middle-income countries, community-level surgical epidemiology is largely undefined. Accurate community-level surgical epidemiology is necessary for surgical health systems planning. To determine the prevalence of surgical conditions in Burera District, Northern Province, Rwanda. A cross-sectional study with a 2-stage cluster sample design (at village and household level) was carried out in Burera District in March and May 2012. A team of surgeons randomly sampled 30 villages with probability proportionate to village population size, then sampled 23 households within each village. All available household members were examined. The presence of 10 index surgical conditions (injuries/wounds, hernias/hydroceles, breast masses, neck masses, obstetric fistulas, undescended testes, hypospadias, hydrocephalus, cleft lip/palate, and clubfoot) was determined by physical examination. Prevalence was estimated overall and for each condition. Multivariable logistic regression was performed to identify factors associated with surgical conditions, accounting for the complex survey design. Of the 2165 examined individuals, 1215 (56.2%) were female. The prevalence of any surgical condition among all examined individuals was 12% (95% CI, 9.2-14.9%). Half of conditions were hernias/hydroceles (49.6%), and 44% were injuries/wounds. In multivariable analysis, children 5 years or younger had twice the odds of having a surgical condition compared with married individuals 21 to 35 years of age (reference group) (odds ratio [OR], 2.2; 95% CI, 1.26-4.04; P = .01). The oldest group, people older than 50 years, also had twice the odds of having a surgical condition compared with the reference group (married, aged >50 years: OR, 2.3; 95% CI, 1.28-4.23; P = .01; unmarried, aged >50 years: OR, 2.38; 95% CI, 1.02-5.52; P = .06). Unmarried individuals 21 to 35 years of age and unmarried individuals aged 36 to 50 years had higher odds of a surgical condition compared with the

A linear degenerate odd Poisson bracket (antibracket) realized solely on Grassmann variables is proposed. It is revealed that this bracket has at once three Grassmann-odd nilpotent Δ-like differential operators of the first, second and third orders with respect to the Grassmann derivatives. It is shown that these Δ-like operators, together with the Grassmann-odd nilpotent Casimir function of this bracket, form a finite-dimensional Lie superalgebra

The number of lymph nodes found to be involved in an axillary dissection is among the most powerful prognostic factors in breast cancer, but it is confounded by the number of lymph nodes that have been examined. We investigate an idea that has surfaced recently in the literature (since 1999), namely that the proportion of node-positive lymph nodes (or a function thereof) is a much better predictor of survival than the number of excised and node-positive lymph nodes, alone or together. The data were abstracted from 83,686 cases registered in the Surveillance, Epidemiology, and End Results (SEER) program of women diagnosed with nonmetastatic T1–T2 primary breast carcinoma between 1988 and 1997, in whom axillary node dissection was performed. The end-point was death from breast cancer. Cox models based on different expressions of nodal involvement were compared using the Nagelkerke R 2 index (R 2 N ). Ratios were modeled as percentage and as log odds of involved nodes. Log odds were estimated in a way that avoids singularities (zero values) by using the empirical logistic transform. In node-negative cases both the number of nodes excised and the log odds were significant, with hazard ratios of 0.991 (95% confidence interval 0.986–0.997) and 1.150 (1.058–1.249), respectively, but without improving R 2 N . In node-positive cases the hazard ratios were 1.003–1.088 for the number of involved nodes, 0.966–1.005 for the number of excised nodes, 1.015–1.017 for the percentage, and 1.344–1.381 for the log odds. R 2 N improved from 0.067 (no nodal covariate) to 0.102 (models based on counts only) and to 0.108 (models based on ratios). Ratios are simple optimal predictors, in that they provide at least the same prognostic value as the more traditional staging based on counting of involved nodes, without replacing them with a needlessly complicated alternative. They can be viewed as a per patient standardization in which the number of involved nodes is standardized

Objectives The current study is the first to assess pregnant women's perceptions of e-cigarettes and the prevalence of e-cigarette use during pregnancy, using a national sample of pregnant women (N = 445) recruited online. Methods An online survey was used to assess the prevalence and perceptions of e-cigarette use among pregnant women, including perceptions of e-cigarette safety. Results In our sample, 5.62% (n = 25) of women solely used tobacco cigarettes, 6.52% (n = 29) solely used e-cigarettes, 8.54% (n = 38) used both tobacco cigarettes and e-cigarettes, and 79.33% (n = 353) used neither tobacco cigarettes nor e-cigarettes during their current pregnancy. Overall, 64.27% (n = 286) of participants viewed e-cigarettes as being safer than tobacco cigarettes. Having seen advertisements for e-cigarettes increased likelihood of viewing them as safer than tobacco cigarettes (OR [Odds Ratio] = 2.5, p many women use e-cigarettes during pregnancy as tobacco cigarettes, that pregnant women view e-cigarettes as being safer than tobacco cigarettes, and that these views may be influenced by exposure to e-cigarette advertisements.

A note on Youden's J and its cost ratio

Smits Niels

2010-09-01

Full Text Available Abstract Background The Youden index, the sum of sensitivity and specificity minus one, is an index used for setting optimal thresholds on medical tests. Discussion When using this index, one implicitly uses decision theory with a ratio of misclassification costs which is equal to one minus the prevalence proportion of the disease. It is doubtful whether this cost ratio truly represents the decision maker's preferences. Moreover, in populations with a different prevalence, a selected threshold is optimal with reference to a different cost ratio. Summary The Youden index is not a truly optimal decision rule for setting thresholds because its cost ratio varies with prevalence. Researchers should look into their cost ratio and employ it in a decision theoretic framework to obtain genuinely optimal thresholds.

Knowledge of the prevalence and risk factors associated with maternal infection is the first step to develop a surveillance system for congenital transmission of Chagas disease. We conducted a cross-sectional study in Casanare, a disease-endemic area in Colombia. A total of 982 patients were enrolled in the study. A global prevalence of Trypanosoma cruzi infection of 4.0% (95% confidence interval [CI] = 2.8–5.3%) was found. Multivariate analysis showed that the most important risk-associated factors were age > 29 years (adjusted odds ratio [aOR] = 3.4, 95% CI = 0.9–12.4), rural residency (aOR = 2.2, 95% CI = 1.0–4.6), low education level (aOR = 10.2, 95% CI = 1.6–82.7), and previous knowledge of the vector (aOR = 2.2, 95% CI = 1.0–4.9). Relatives and siblings of infected mothers showed a prevalence of 9.3%. These findings may help physicians to investigate congenital cases, screen Chagas disease in siblings and relatives, and provide early treatment to prevent the chronic complications of Chagas disease.

PARITY ODD BUBBLES IN HOT QCD.

We consider the topological susceptibility for an SU(N) gauge theory in the limit of a large number of colors, N {r_arrow} {infinity}. At nonzero temperature, the behavior of the topological susceptibility depends upon the order of the deconfining phase transition. The most interesting possibility is if the deconfining transition, at T = T{sub d}, is of second order. Then we argue that Witten's relation implies that the topological susceptibility vanishes in a calculable fashion at Td. As noted by Witten, this implies that for sufficiently light quark masses, metastable states which act like regions of nonzero {theta}--parity odd bubbles--can arise at temperatures just below T{sub d}. Experimentally, parity odd bubbles have dramatic signatures: the {eta}{prime} meson, and especially the {eta} meson, become light, and are copiously produced. Further, in parity odd bubbles, processes which are normally forbidden, such as {eta} {r_arrow} {pi}{sup 0}{pi}{sup 0}, are allowed. The most direct way to detect parity violation is by measuring a parity odd global asymmetry for charged pions, which we define.

Full Text Available Background. There are very few studies that had a sample size sufficient to explore the association between factors related to low back pain in a representative sample of the Iranian population. Objective. To examine the relationship between sociodemographic factors, smoking, obesity, and low back pain in Iranian people. Methods. We used Iranian adults respondents (n=25307 from the National Health Survey. Adjusted odds ratios and 95% confidence intervals were estimated by using logistic regression. Results. The prevalence of low back pain was found in 29.3% of the studied sample. High age, female sex, being married, obesity, low-economic index, being smoker, in a rural residence, and low educational attainment, all increased the odds of low back pain. Conclusions. Our findings add to the evidence on the importance of obesity in relation to low back pain. These results can be used as a basis to reinforce health programs to prevent obesity.

Various epidemiological studies indicate that the prevalence of intestinal parasites is high in developing countries and those parasites are major public health importance in Sub-Saharan Africa. Their distribution is mainly associated with poor personal hygiene, environmental sanitation and lack of access to clean water. This study was conducted to estimate the prevalence of intestinal parasitic infection and identify factors associated with intestinal parasitic infection among food handlers in the Aksum Town of Tigray Regional State, North Ethiopia. A cross-sectional study design was used among 400 randomly selected food handlers who were selected as respondents. Data were collected by face to face interviewer administered questionnaire supplemented with observational checklist. Fresh stool samples were collected from respondents and were examined microscopically for the presence of any of intestinal parasites using standard laboratory methods. Multivariable logistic regression model using Adjusted Odds Ratio (AOR) and 95% Confidence Interval (CI) was fitted to analyze the independent predictors of intestinal parasitic infections. The mean age of the food handlers included in this study was 26.0 years. Of the total respondents, 72.5% were females, 63% have completed at least secondary school educational level. Five species of Intestinal Parasites (IPs) were identified. The overall prevalence of being infected with at least one intestinal parasite was 14.5%, 95% CI (11.3, 18.0). The odds of being positive for at least one intestinal parasitic infection was 12.3 times higher among food handlers who practice medical checkup every 9 months compared to those who have a medical checkup every 3 months. The odds of being positive for intestinal parasitic infection was 3 times higher among food handlers with no formal education compared to those who have a level of education secondary school and above. Food handlers who received food hygiene and safety training were 66

Revisiting the concept of ‘chronic disease’ from the perspective of the episode of care model. Does the ratio of incidence to prevalence rate help us to define a problem as chronic?

Full Text Available Background This is a study of the epidemiology of acute and chronic episodes of care (EoCs in the Transition Project in three countries. We studied the duration of EoCs for acute and chronic health problems and the relationship of incidence to prevalence rates for these EoCs.Method The Transition Project databases collect data on all elements of the doctor–patient encounter in family medicine. Family doctors code these elements using the International Classification of Primary Care.We used the data from three practice populations to study the duration of EoCs and the ratio of incidence to prevalence for common health problems.Results We found that chronic health problems tended to have proportionately longer duration EoCs, as expected, but also a lower incidence to prevalence rate ratio than acute health problems. Thus, the incidence to prevalence index could be used to define a chronic condition as one with a low ratio, below a defined threshold.Conclusions Chronic health problems tend to have longer duration EoCs, proportionately, across populations. This result is expected, but we found important similarities and differences which make defining a problem as chronic on the basis of time rather difficult. The ratio of incidence to prevalence rates has potential to categorise health problems into acute or chronic categories, at different ratio thresholds (such as 20, 30 or 50%. It seems to perform well in this study of three family practice populations, and is proposed to the scientific community for further evaluation.

Full Text Available Investigou-se a prevalência de sobrepeso e obesidade e respectivos fatores associados em escolares mexicanos. O estudo teve delineamento transversal e amostra composta por 700 escolares. As prevalências de sobrepeso e obesidade foram calculadas segundo sexo e idade, e as medidas de associação (odds ratios estimadas por pontos e por intervalos, utilizando-se a regressão logística multivariada. Para o conjunto de escolares, as prevalências de sobrepeso e obesidade foram 28,1% e 13,7%, respectivamente. Os fatores de risco para o sobrepeso foram: "número de anos de escolaridade da mãe"; "hábito de comer enquanto estuda ou assiste à TV"; "escores de freqüência de consumo de alimentos de risco > 12 pontos"; "atividades sedentárias > 1,6 horas/dia" e "peso ao nascer > 2.890 gramas". Os fatores de risco para a obesidade foram semelhantes àqueles detectados para o sobrepeso. Maior freqüência de atividades esportivas foi identificada como fator de proteção para ambos os desfechos. A detecção dos principais fatores associados ao sobrepeso e à obesidade indica o direcionamento de intervenções para a prevenção de doenças crônicas nessa população, cujos fatores de risco já podem ser identificados a partir da infância.This study aimed to investigate the prevalence rates for overweight and obesity among Mexican schoolchildren, identifying factors associated with the outcomes.

To examine the associations with symptoms of 1) burnout and 2) work-related posttraumatic stress, in adult and pediatric intensive care staff, focusing on the particular contributions of resilience and coping strategies. Point prevalence cross-sectional study. Three adult ICUs and four PICUs. Three hundred seventy-seven ICU staff. None. Brief Resilience Scale, abbreviated Maslach Burnout Inventory, Trauma Screening Questionnaire, and Hospital Anxiety and Depression Scale. Prevalence of burnout (defined as high emotional exhaustion or high depersonalization) was 37%. Prevalence of clinically significant posttraumatic stress symptoms was 13%. There was a degree of overlap between burnout and other measures of distress, most notably for anxiety (odds ratio, 10.56; 95% CI, 4.12-27.02; p work-related distress (burnout: odds ratio, 0.52; 95% CI, 0.36-0.74; p stress: odds ratio, 0.28; 95% CI, 0.16-0.46; p stress were less if staff used talking to seniors (odds ratio, 0.43; 95% CI, 0.20-0.92; p = 0.029) or hobbies (odds ratio, 0.46; 95% CI, 0.23-0.93; p = 0.030) to cope with stress at work. Venting emotion (odds ratio, 1.92; 95% CI, 1.12-3.31; p = 0.018) and using alcohol (odds ratio, 2.30; 95% CI, 1.26-4.20; p = 0.006) were associated with a doubling in risk of reporting burnout. The use of particular coping strategies was systematically associated with symptoms of burnout and work-related posttraumatic stress in this group of intensive care staff, even after controlling for resilience and other factors. More research on how best to promote adaptive coping is needed in these challenging settings.

The burden of cardiovascular diseases (CVD) is increasing in most countries of sub-Saharan Africa. However, as there is a scarcity of data, little is known about CVD in Angola. This study aimed to determine the prevalence of prehypertension, hypertension, prediabetes, diabetes, overweight, and obesity among workers at a private tertiary center in Angola. A cross-sectional study was conducted among 781 workers of Clínica Girassol, a tertiary health care center in Angola, during the month of November 2013. Demographic, anthropometric, and clinical variables were analyzed. Of the 781 participants studied, 50.44% were males and 78.11% were under 40 years old. The prevalence of hypertension and prehypertension was 17.93% (95% confidence interval [CI]: 15.24%-20.74%) and 54.03% (95% CI: 50.58%-57.62%), respectively. Among hypertensive subjects, 83.57% (117) were unaware of the diagnosis. Hypertension was associated with age (≥40 years) (odds ratio [OR]: 6.21; 95% CI: 4.18-9.24; P Angola.

Commercial sex represents a critical context for HIV transmission within India and elsewhere. Despite research and programmatic attention to commercial sex workers (CSWs), less is known concerning the male CSW clients considered a bridge population for HIV transmission to the general population and thought to drive demand for the sex trafficking of women and girls. The current study assesses the prevalence of past year CSW contact, condom nonuse therein, and associations with demographic characteristics and gendered attitudes among a national sample of Indian men. The nationally representative Indian National Family Health Survey-3 was conducted across all Indian states in 2005-2006; the current sample was limited to 46,961 sexually active men. Analyses calculated the prevalence of past year CSW contact and inconsistent condom use; adjusted logistic regression models were used to evaluate associations of demographic characteristics, sexual entitlement and justification of wife abuse with past year CSW contact, and inconsistent condom use. Approximately 1 in 100 Indian men (0.9%) reported past year CSW contact; over half of such men reported inconsistent condom use with CSWs. CSW contact was most common among men ages 15-24 (3.6%) and never married men (9.9%). Men's CSW contact related to higher levels of sexual entitlement (adjusted odds ratio = 1.64; 95% confidence interval 1.24 to 2.17) and justification of violence against wives (adjusted odds ratio = 1.41; 95% confidence interval: 1.03 to 1.93). Men's past year CSW contact was concentrated among young and unmarried Indian men; condom nonuse with CSWs was common. Traditional gender ideologies seemed to support men's CSW contact, bolstering consideration of this behavior as a gendered form of HIV risk. Findings provide direction for interventions to reduce men's CSW contact in the Indian context by describing high-risk subpopulations and indicating that gender ideologies should be addressed.

Assessment of the likelihood ratio (LR) of symptoms has been proposed as a rational means for detecting indicators to homeopathic medicines. To investigate the prevalence and LR of symptoms commonly attributed to the homeopathic medicine Lycopodium clavatum (Lyc). Secondarily, to answer the question if experienced homeopaths could intuitively infer which the main symptoms of this medicine are. The presence of 35 selected symptoms, prescribed medicines and therapeutic response were assessed retrospectively. The symptoms' prevalence in the Lyc responding population and the LR of the symptoms compared to their prevalence in the remainder of the population were calculated. Two hundred and two Lyc and 550 non Lyc cases (total 752) were included for analysis. Twenty-two symptoms were confirmed as pertaining to Lyc's semiology (prevalence %; LR): contemptuous (3.3; 6.7), urinary stones history (2.7; 5.4), egotism (5.6; 3.6), dictatorial (33.3; 3.4), haughty (8.7; 3.3), sleeps on abdomen (3.3; 3.3), intolerance to clothing in abdomen (12.0; 3.1), reproaches (4.0; 3.0), helplessness (24.0; 2.7), fear of failure (10.7; 2.6), irritability on waking in the morning (16.7; 2.5), constipation alternating with diarrhea (8.7; 2.5), intolerant to contradiction (59.3; 2.3), want of self confidence (30.0; 2.4), abdominal distension after eating (23.3; 2.1); ailments from anticipation (32.0; 1.9), irritability before menses (23.3; 1.8), conscientious (26.0; 1.6), desire of sweets (52.0; 1.6), desire of chocolate (16.7; 1.6), lack of vital heat (41.3; 1.3), and flatterer (1.3; ∞). Surveyed homeopaths' intuitive inferences correlated well with symptoms' prevalence but not with their LR. Lycopodium's main symptoms are well known by homeopaths, but their knowledge correlates well with the symptoms' prevalence and not with their LR. Retrospective assessment of prevalence and LR of symptoms in good responders might be a means for better selection of symptoms for prospective studies

Economic abuse is a form of domestic violence that has a significant impact on the health and financial wellbeing of victims, but is understudied. This study determined the lifetime prevalence of economic abuse in Australia by age and gender, and the associated risk factors. The 2012 ABS Personal Safety Survey was used, involving a cross-sectional population survey of 17,050 randomly selected adults using face-to-face interviews. The survey-weighted prevalence of economic abuse was calculated and analysed by age and gender. Logistic regression was used to adjust odds ratios for possible confounding between variables. The lifetime prevalence of economic abuse in the whole sample was 11.5%. Women in all age groups were more likely to experience economic abuse (15.7%) compared to men (7.1%). Disability, health and financial stress status were significant markers of economic abuse. For women, financial stress and disability were important markers of economic abuse. However, prevalence rates were influenced by the measures used and victims' awareness of the abuse, which presents a challenge for screening and monitoring. Implications for public health: Social, health and financial services need to be aware of and screen for the warning signs of this largely hidden form of domestic violence. © 2017 The Authors.

Full Text Available Food wastes are sources of compounds that can be used as natural additives in the food and feed industry. The olive oil industry produces two main wastes: aqueous waste (olive mill wastewater and solid waste (pomace or olive cake. These by-products are rich in phenols, which are antioxidant and antimicrobial compounds able to inhibit or delay the growth of several bacteria in vitro. The dietary effect of both olive mill wastewater polyphenolic extract (OMWPE and dehydrated olive cake (DOC on the prevalence of Campylobacter spp. in broiler chickens was investigated. A commercial basal diet was supplemented with either OMWPE- or DOC-enriched maize at two dosages (low: 16%; high: 33%. The prevalence of Campylobacter spp. shedding was evaluated at 21, 35, and 49 days of age. The prevalence of Campylobacter spp. differed among groups only at 49 days of age. Both OMWPE groups showed a lower (p < 0.05 prevalence compared to the control group. The odds ratio evaluation showed that the higher dose of OMWPE reduced the possibility of shedding 11-fold compared to the control group (p < 0.001. These results highlight the potential use of olive by-products against Campylobacter spp. in poultry.

Full Text Available BACKGROUND: Patients with type 2 diabetes (DM have a higher risk of developing pulmonary tuberculosis (PTB; moreover, DM co-morbidity in PTB is associated with poor PTB treatment outcomes. Community based prevalence data on DM and prediabetes (pre-DM among TB patients is lacking, particularly from the developing world. Therefore we conducted a prospective study to investigate the prevalence of DM and pre-DM and evaluated the risk factors for the presence of DM among newly detected PTB patients in rural areas of China. METHODS AND FINDINGS: In a prospective community based study carried out from 2010 to 2012, a representative sample of 6382 newly detected PTB patients from 7 TB clinics in Linyi were tested for DM. A population of 6674 non-TB controls from the same community was similarly tested as well. The prevalence of DM in TB patients (6.3% was higher than that in non-TB controls (4.7%, p<0.05. PTB patients had a higher odds of DM than non-TB controls (adjusted OR 3.17, 95% CI 1.14-8.84. The prevalence of DM increased with age and was significantly higher in TB patients in the age categories above 30 years (p<0.05. Among TB patients, those with normal weight (BMI 18.5-23.9 had the lowest prevalence of DM (5.8%. Increasing age, family history of DM, positive sputum smear, cavity on chest X-ray and higher yearly income (≥10000 RMB yuan were positively associated and frequent outdoor activity was negatively associated with DM in PTB patients. CONCLUSIONS: The prevalence of DM in PTB patients was higher than in non-TB controls with a 3 fold higher adjusted odds ratio of having DM. Given the increasing DM prevalence and still high burden of TB in China, this association may represent a new public health challenge concerning the prevention and treatment of both diseases.

Full Text Available Some published evidence has revealed that the dendritic cells can interact with pathogens that exist in the inner foreskin. This information provides a new vision that pathogens could play a role through the redundant prepuce; numerous studies have failed to find pathogens in prostates of patients who had chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS. However, no studies have reported an association between foreskin length and CP/CPPS. Hence, we conducted a retrospective case-control study of clinical data from 322 CP/CPPS patients (case group and 341 nonCP/CPPS patients (control group. Demographic characteristics, lifestyle factors, and foreskin lengths were collected and analyzed. Multivariate logistic regression was adopted to calculate the odds of foreskin length for CP/CPPS. According to the multivariate logistic regression results, when the foreskin length covered up more than half of the glans penis, the odds for CP/CPPS were higher with an increased foreskin (odds ratio (OR: 1.66, 95% confidence interval (CI: 1.04-2.66. In comparison, when the glans penis was completely covered by the foreskin, the OR value increased to 1.86 (95% CI, 1.2-2.88. The study results showed an association between foreskin length and the odds of CP/CPPS. When the foreskin length covered up more than half of the glans penis, there were greater odds for CP/CPPS. This possible mechanism might result from interaction between pathogens and DCs in the inner foreskin, consequently activating T-cells to mediate allergic inflammation in the prostate and producing the autoimmunizations causing CP/CPPS.

General aviation (GA) accidents have continued to demonstrate high fatality rates. Recently, ballistic parachute recovery systems (BPRS) have been introduced as a safety feature in some GA aircraft. This study evaluates the effectiveness and associated factors of the Cirrus Airframe Parachute System (CAPS) at reducing the odds of a fatal accident in Cirrus aircraft crashes. Publicly available Cirrus aircraft crash reports were obtained from the National Transportation Safety Board (NTSB) database for the period of January 1, 2001-December 31, 2016. Accident metrics were evaluated through univariate and multivariate analyses regarding odds of a fatal accident and use of the parachute system. Included in the study were 268 accidents. For CAPS nondeployed accidents, 82 of 211 (38.9%) were fatal as compared to 8 of 57 (14.0%) for CAPS deployed accidents. After controlling for all other factors, the adjusted odds ratio for a fatal accident when CAPS was not deployed was 13.1. The substantial increased odds of a fatal accident when CAPS was not deployed demonstrated the effectiveness of CAPS at providing protection of occupants during an accident. Injuries were shifted from fatal to serious or minor with the use of CAPS and postcrash fires were significantly reduced. These results suggest that BPRS could play a significant role in the next major advance in improving GA accident survival.Alaziz M, Stolfi A, Olson DM.

Heavy-ion reactions induce large amounts of angular momentum; hence, they selectively populate rotationally-aligned particle states in compound nuclei. Such states tend to deexcite through similar states connected by large coriolis matrix elements, resulting in relatively few - but highly distorted - bands in the lower-energy portions of odd-odd spectra. The extreme cases of this are doubly-decoupled, K ∼ 1 (π 1/2 x ν 1/2) bands, whose γ transitions are the most intense in spectra from many light Re and Ir nuclei. The authors made a two-pronged assault on such bands, studying them via different HI reactions at different laboratories and using interacting-boson (IBFFA) calculations to aid in sorting them out. The authors are beginning to understand the types of (primarily coriolis) distortions involved and hope to grasp a handle on aspects of the p-n residual interaction, although the coriolis distortions are large enough to mask much of the latter. They also discuss similar but complementary effects in the light Pr region

Transmission of tuberculosis (TB) to health care workers (HCWs) is a global issue. Although effective infection control measures are expected to reduce nosocomial TB, HCWs' infection has not been assessed enough in TB high burden countries. We conducted a cross-sectional study to determine the prevalence of TB infection and its risk factors among HCWs in Hanoi, Viet Nam. A total of 300 HCWs including all staff members in a municipal TB referral hospital received an interferon-gamma release assay (IGRA), QuantiFERON-TB Gold In-Tube(TM), followed by one- and two-step tuberculin skin test (TST) and a questionnaire-based interview. Agreement between the tests was evaluated by kappa statistics. Risk factors for TB infection were analyzed using a logistic regression model. Among the participants aged from 20 to 58 years (median = 40), prevalence of TB infection estimated by IGRA, one- and two-step TST was 47.3%, 61.1% and 66.3% respectively. Although the levels of overall agreement between IGRA and TST were moderate, the degree of agreement was low in the group with BCG history (kappa = 0.29). Working in TB hospital was associated with twofold increase in odds of TB infection estimated by IGRA. Increased age, low educational level and the high body mass index also demonstrated high odds ratios of IGRA positivity. Prevalence of TB infection estimated by either IGRA or TST is high among HCWs in the hospital environment for TB care in Viet Nam and an infection control program should be reinforced. In communities with heterogeneous history of BCG vaccination, IGRA seems to estimate TB infection more accurately than any other criteria using TST.

Full Text Available There are no published data on national lifetime prevalence and treatment of mental disorders in the Arab region. Furthermore, the effect of war on first onset of disorders has not been addressed previously on a national level, especially in the Arab region. Thus, the current study aims at investigating the lifetime prevalence, treatment, age of onset of mental disorders, and their relationship to war in Lebanon.The Lebanese Evaluation of the Burden of Ailments and Needs Of the Nation study was carried out on a nationally representative sample of the Lebanese population (n = 2,857 adults. Respondents were interviewed using the fully structured WHO Composite International Diagnostic Interview 3.0. Lifetime prevalence of any Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV disorder was 25.8%. Anxiety (16.7% and mood (12.6% were more common than impulse control (4.4% and substance (2.2% disorders. Only a minority of people with any mental disorder ever received professional treatment, with substantial delays (6 to 28 y between the onset of disorders and onset of treatment. War exposure increased the risk of first onset of anxiety (odds ratio [OR] 5.92, 95% confidence interval [CI] 2.5-14.1, mood (OR 3.32, 95% CI 2.0-5.6, and impulse control disorders (OR 12.72, 95% CI 4.5-35.7.About one-fourth of the sample (25.8% met criteria for at least one of the DSM-IV disorders at some point in their lives. There is a substantial unmet need for early identification and treatment. Exposure to war events increases the odds of first onset of mental disorders.

The total potential energy surfaces of thallium, gold, iridium and rhenium odd mass isotopes are calculated microscopically as functions of the quadrupole deformation, epsilon /sub 2/, when the odd protons occupy definite orbitals. The nuclear shapes and the static equilibrium deformations of these nuclei are deduced from the results of these calculations for the proton orbitals nearest to the Fermi level. The influence of the hexadecapole deformation, epsilon /sub 4/, on these results is investigated too. Finally, a few experimental data available for these odd mass nuclei are correlated to the corresponding theoretical results. (16 refs).

Metabolic Syndrome (MS) increases the risk of diabetes and mortality associated with cardiovascular disease. However, the prevalence of MS could differ by ethnicity and lifestyle factors. To determine the prevalence of MS in Mapuche individuals living in urban and rural environments in Chile and to investigate whether the prevalence and risk of MS in urban and rural environments differs by sex, age and nutritional status. A total of 1077 Mapuche participants were recruited from urban (MU = 288) and rural (MR = 789) settings. Body mass index, waist circumference and blood pressure were measured. A fasting blood sample was obtained to measure serum glucose, HDL cholesterol and triacylglycerol. The prevalence of MS was determined using the unified IDF and ATP-III criteria. An environment and sex interaction was found for the prevalence of MS (p = 0.042). The prevalence was significantly lower in male MR (13%) compared to other groups (22, 23 and 25% among female MR, female MU and male MU respectively). Also, the prevalence of central obesity and low HDL-cholesterol were significantly lower in male MR. MU are at an increased risk of developing MS compared to MR, with an odds ratio of 1.59 (95% confidence intervals 1.1 to 2.2). This risk increases along with age or body mass index of the population. The adoption of an urbanized lifestyle increases the risk of developing MS in Mapuche individuals. This risk is enhanced by age and nutritional status.

Students use it to help them study for long hours especially during the period of examination. However, how regularly khat is chewed among university students and its associated factors are not well documented. In this article we report on the prevalence of and factors associated with regular khat chewing among university students in Ethiopia. Methods: We did a cross-sectional study from May 20, 2014 to June 23, 2014 on a sample of 1,255 regular students recruited from all campuses of Hawassa University, southern Ethiopia. The data were collected using self-administered questionnaires. We analyzed the data to identify factors associated with current regular khat chewing using complex sample adjusted logistic regression analysis. Results: The prevalence of current regular khat chewing was 10.5% (95% confidence interval [CI]: 6.1%–14.9%. After controlling for sex, religion, year of study, having a father who chews khat, cigarette smoking and alcohol drinking in the adjusted logistic regression model, living off-campus in rented houses as compared to living in the university dormitory (adjusted odds ratio [95% CI] =8.09 [1.56–42.01], and having friends who chew khat (adjusted odds ratio [95% CI] =4.62 [1.98–10.74] were found to significantly increase the odds of current regular khat use. Conclusion: Students living outside the university campus in rented houses compared to those living in dormitory and those with khat chewing peers are more likely to use

The process by which odd nitrogen species (atomic nitrogen and nitric oxide) are formed during atmospheric entry of meteoroids is analyzed theoretically. An ablating meteoroid is assumed to be a point source of mass with a continuum regime evolving in its wake. The amounts of odd nitrogen species, produced by high-temperature reactions of air in the continuum wake, are calculated by numerical integration of chemical rate equations. Flow properties are assumed to be uniform across the wake, and 29 reactions involving five neutral species and five singly ionized species are considered, as well as vibrational and electron temperature nonequilibrium phenomena. The results, when they are summed over the observed mass, velocity, and entry-angle distribution of meteoroids, provide odd-nitrogen-species annual global production rates as functions of altitude. The peak production of nitric oxide is found to occur at an altitude of about 85 km; atomic nitrogen production peaks at about 95 km. The total annual rate for nitric oxide is 40 million kg; for atomic nitrogen it is 170 million kg.

Of 921 patients with normal renal function at baseline, 117 (12.7%) developed renal impairment during a median follow-up (interquartile range) of 6.2 (0.4-14.7) months. The incidence of renal impairment was 110 cases per 1000 person-years (95% confidence interval [CI], 92-132). At enrollment, logistic regression identified older age (adjusted odds ratio [aOR], 1.79; 95% CI, 1.52-2.11), hypertension (aOR, 1.84; 95% CI, 1.08-3.15), CD4 count impairment. Cox regression model confirmed older age (adjusted hazard ratio [aHR], 1.85; 95% CI, 1.56-2.20) and CD4 count impairment. Our study found a low prevalence of renal impairment among PLWHIV despite high usage of tenofovir and its association with age, hypertension, low CD4 count, and advanced WHO stage. These important and reassuring safety data stress the significance of noncommunicable disease surveillance in aging HIV populations in sub-Saharan Africa.

The coexistence of hypertension (HTN) and diabetes mellitus (DM) increases the risk of cardiovascular disease. In some studies, normal albuminuria has also been associated with cardiovascular disease and HTN. Therefore, we examined the relationships between albuminuria and the prevalence of HTN and its control rate in type 2 DM patients. We analyzed data from the 2011-2012 Korea National Health and Nutrition Examination Survey, and 1188 subjects with type 2 DM were included in the study. We divided albuminuria into 3 albuminuria tertiles (T): T1: hypertension had more ACR T3 (odds ratio=2.018, 95% confidence interval=1.445-2.818) than subjects without HTN. Subjects with controlled HTN had less ACR T3 than subjects without controlled HTN (odds ratio=0.566, 95% confidence interval=0.384-0.836). When, we redivided albuminuria by Diabetes Europe.

There is a known association between congenital heart disease (CHD) and other congenital anomalies (CA). These associations have been altered by changes in prenatal factors in recent time. We reviewed the largest database of inpatient hospitalization information and analyzed the current association between common CHD diagnoses and other congenital anomalies. Case-control study design. We reviewed the Nationwide Inpatient Sample (NIS) database from 1998 to 2008 and identified all live births with CHD diagnosis (case) and live births without CHD diagnosis (control). We compared prevalence of associated congenital anomalies between the case and control groups. Our cohort consisted of 97,154 and 12,078,482 subjects in the case and control groups, respectively. In the CHD population, prevalence of non-syndromic congenital anomaly (NSCA), genetic syndrome (GS), and overall extra-cardiac congenital anomaly (CA) were 11.4, 2.2, and 13.6%, respectively. In the control group, prevalence of NSCA, GS, and CA were 6.7, 0.3, and 7.0%, respectively. NSCA (odds ratio (OR): 1.88, confidence interval (CI): 1.73-1.94), GS (OR 2.52, CI 2.44-2.61), and overall CA (OR: 2.01, CI: 1.97-2.14) were strongly associated with CHD. Prevalence of GS and multiple organ-system CA decreased significantly over the study period. This is the largest and most comprehensive population-based study evaluating association between CHD and extra-cardiac malformation (ECM) in newborns. There was significant decrease in prevalence of GS and multiple CA over the study period

To investigate prevalence of urinary incontinence (UI) in a multi-ethnic population of pregnant women, and to analyse for possible associations of the known risk factors for UI in such a population. Population-based cross-sectional study. All pregnant women in three administrative city districts attending the Child Health Clinics. Out of 823 women identified in the [corrected] first trimester, 772 (94%) [corrected] agreed to participate in the study at 28 weeks of gestation. Inclusion criteria were: healthy women at 20 weeks of gestation or less and able to communicate in Norwegian, Arabic, English, Sorani, Somali, Tamil, Turkish, Urdu or Vietnamese. Differences between ethnic groups were tested by simple descriptive statistics. Associations were estimated by logistic regression analysis and presented as crude (cOR) and adjusted (aOR) odds ratios. Prevalence of UI as ascertained using the International Consultation on Incontinence Questionnaire-urinary incontinence-short form. Prevalence rates of UI at 28 weeks of gestation were 26% for women of African origin, 36% for women of Middle Eastern origin, 40% for women of East Asian origin, 43% for women of South Asian origin and 45% for women of European/North American origin. The difference was significant between women of African and European/North American origins (P = 0.011) and between women of African and South Asian origins (P = 0.035). Age (aOR 1.05; 95% CI 1.01-1.09) and parity (aOR 2.34; 95% CI 1.66-3.28) were positively associated with the prevalence of UI in pregnancy. Women of African origin had significantly reduced odds for UI (aOR 0.42; 95% CI 0.20-0.87). East Asian and African women reported the highest perceived impact of UI in pregnancy. A high prevalence of UI was found in a multi-ethnic pregnant population. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

Purpose: The purpose of this study was to determine the prevalence of a history of ocular trauma and its association to age, sex, and biometric components. Materials and Methods: Residents of Shahroud, Iran aged 40–64 years, were sampled through a cross-sectional study using multistage cluster sampling. Three hundred clusters were randomly selected, and 20 individuals were systematically selected from each cluster. The subjects underwent optometric and ophthalmic examinations, and ocular imaging. A history of ocular trauma was determined through personal interviews. Results: The prevalence of a history of trauma and blunt trauma, sharp trauma, and chemical burns were 8.57%, 3.91%, 3.82%, and 1.93%, respectively. After adjusting for age, the rate of all types of trauma was significantly higher for males. Only the prevalence of chemical burns significantly decreased with aging. A history of hospitalization was stated by 1.64% of the subjects. The axial length was significantly longer in cases with a history of trauma. The corneal curvature was significantly larger in cases with a history of sharp trauma and chemical burns. The prevalence of corneal opacities was significantly higher among cases with a history of the blunt trauma odds ratio (OR = 2.33) and sharp trauma (OR = 4.46). Based on corrected visual acuity, the odds of blindness was 3.32 times higher in those with a history of ocular trauma (P < 0.001). Conclusion: A considerable proportion of the 40–64-year-old population reported a history of ocular trauma. This observation has important health implications. Blindness, corneal opacities, and posterior subcapsular cataract were observed more frequently among these cases, and they demonstrated differences in some ocular biometric components. PMID:26180480

Anaemia is a public health problem affecting over 1.62 billion people globally. It affects all age groups of people and is particularly more prevalent in pregnant women. Africa carries a high burden of anaemia; in Uganda 24 % of women of child bearing age have anaemia. Pregnant women living in poverty are at greater risk of developing iron deficiency anaemia. The objective of this study was to determine the prevalence of anaemia and the associated risk factors in pregnant women attending antenatal care at Gulu and Hoima Regional Hospitals in Northern and Western Uganda respectively. We conducted a cross sectional study in Gulu and Hoima Regional Hospitals from July to October 2012. Our study participants were pregnant women attending antenatal care. Socio-demographic data were collected using structured questionnaires and blood samples were collected for haemoglobin estimation. Haemoglobin concentration was determined using an automated analyzer closed mode of blood sampling. Data were analysed using Stata version 12. Odds ratio was used as a measure of association, with 95% confidence interval; and independent risk factors for anaemia were investigated using logistic regression analyses. Ethical approval was obtained from Gulu University Research Ethics Committee and written informed consent was obtained from each study participant. The overall prevalence of anaemia was 22.1%; higher in Gulu (32.9%) than in Hoima (12.1%), p prevalence of mild anaemia was 23%, moderate anaemia was 9%, and severe anaemia was 0.8%, while in Hoima, the prevalence of mild anaemia was 9%, moderate anaemia was 2.5%, and severe anaemia was 0.5%. Independent risk factors for anaemia were: being a housewife [Adjusted Odds Ratio (AOR) = 1.7, 95% CI: 1.05-2.68]; and being a resident in Gulu (AOR = 3.6, 95% CI: 2.41-5.58). The prevalence of anaemia in pregnant women in Gulu is higher than in Hoima. Amongst pregnancy women, being a housewife is an independent risk factor for anaemia

Full Text Available Background: Nutritional rickets is a public health concern in developing countries despite tropical climates and a re-emerging issue in developed countries. In this study, we reviewed pediatric admission data from the Clinical Information Network (CIN to help determine hospital and region based prevalence of rickets in three regions of Kenya (Central Kenya, Western Kenya and Nairobi County. We also examine the association of rickets with other diagnosis, such as malnutrition and pneumonia, and study the effect of rickets on regional hospital stays. Methods: We analyzed discharge records for children aged 1 month to 5 years from county (formerly district hospitals in the CIN, with admissions from February 1st 2014 to February 28th 2015. The strength of the association between rickets and key demographic factors, as well as with malnutrition and pneumonia, was assessed using odds ratios. The Fisher exact test was used to test the significance of the estimated odd ratios. Kaplan-Meier curves were used to analyze length of hospital stays. Results: There was a marked difference in prevalence across the three regions, with Nairobi having the highest number of cases of rickets at a proportion of 4.01%, followed by Central Region at 0.92%. Out of 9756 admissions in the Western Region, there was only one diagnosis of rickets. Malnutrition was associated with rickets; this association varied regionally. Pneumonia was found to be associated with rickets in Central Kenya. Children diagnosed with rickets had longer hospital stays, even when cases of malnutrition and pneumonia were excluded in the analysis. Conclusion: There was marked regional variation in hospital based prevalence of rickets, but in some regions it is a common clinical diagnosis suggesting the need for targeted public health interventions. Factors such as maternal and child nutrition, urbanization and cultural practices might explain these differences.

The authors hypothesized that changes in prenatal factors such as termination of pregnancy for fetal anomalies and prenatal vitamin supplementation have altered the epidemiology of patients with multiple congenital anomalies and may have had an impact on their prevalence in the current era. This study reviewed the Nationwide Inpatient Sample database from 1998 to 2008 and compared the prevalence of ECM among live births with a CHD diagnosis (case) and that among live births without a CHD diagnosis (control). For this study, 42 ECM and 10 CHD diagnoses were selected for subanalysis. Longitudinal analysis also was performed to determine temporal variation of ECM prevalence in the CHD population during the 11-year study period. The cohort in this study consisted of 97,154 patients in the case group and 12,078,482 subjects in the control group. The prevalences in the CHD population were 11.4 % for nonsyndromic congenital malformation (NSCM), 2.2 % for genetic syndrome (GS), and 13.6 % for overall extracardiac congenital malformation (ECM). The prevalences in the control group were 6.7 % for NSCM, 0.3 % for GS, and 7.0 % for ECM. The findings showed a strong association of NSCM [odds ratio (OR) 1.88; 95 % confidence interval (CI) 1.73-1.94], GS (OR 2.52; 95 % CI 2.44-2.61), and overall ECM (OR 2.01; 95 % CI 1.97-2.14) with CHD. The prevalences of GS and multiple organ system CM decreased significantly during the study period. This study was the largest and most comprehensive population-based study to evaluate the association between CHD and ECM in newborns.

This study was conducted to estimate the prevalence and associated factors of subjective halitosis in adolescents. In total, 359,263 participants were selected from the Korea Youth Risk Behavior Web-based Survey (KYRBWS) from 2009 through 2013. Demographic data including age, sex, obesity and residency; psychosocial factors such as subjective health, stress, and economic levels; and dietary factors such as alcohol consumption; smoking; and fruit, soda, fast food, instant noodle, confection, and vegetable consumption were analyzed for correlations with halitosis using simple and multiple logistic regression analyses with complex sampling. In total, 23.6% of the participants reported the presence of halitosis. The following subjectively assessed factors were related to halitosis: poor health status (adjusted odds ratio [AOR] = 2.56), overweight or obese (AOR = 1.37), stress (AOR = 2.56), and lower economic levels (AOR = 1.85). The high intake of fast food (AOR = 1.15), instant noodles (AOR = 1.17), and confections (AOR = 1.17) and the low intake of fruits (AOR = 1.22) and vegetables (AOR = 1.19) were also related to halitosis. The prevalence of subjective halitosis in the studied adolescents was 23.6%. Specific psychosocial factors and dietary intake were related to halitosis.

To explore whether chronic pain is associated with cardiovascular risk factors and identify whether increased distribution or intensity of pain is associated with cardiovascular risk, participants in Generation Scotland: The Scottish Family Health study completed pain questionnaires recording the following: presence of chronic pain, distribution of pain, and intensity of chronic pain. Blood pressure, lipids, blood glucose, smoking history, waist-hip ratio, and body mass index were recorded; Framingham 10-year coronary heart disease (CHD) risk scores were calculated and a diagnosis of metabolic syndrome derived. Associations between chronic pain and cardiovascular risk were explored. Of 13,328 participants, 1100 (8.3%) had high CHD risk. Chronic pain was reported by 5209 (39%), 1294 (9.7%) reported widespread chronic pain, and 707 (5.3%) reported high-intensity chronic pain. In age- and gender-adjusted analyses, chronic pain was associated with elevated CHD risk scores (odds ratio 1.11, 95% confidence interval 1.01-1.23) and the metabolic syndrome (odds ratio 1.42, 95% confidence interval 1.24-1.62). Multivariate analyses identified dyslipidaemia, age, gender, smoking, obesity, and high waist-hip ratio as independently associated with chronic pain. Within the chronic pain subgroup, widespread pain did not confer any additional cardiovascular disease risk. However, cardiovascular disease risk factors contributing to metabolic syndrome were more prevalent in those reporting high-intensity chronic pain. This large population-based study has demonstrated that chronic pain, and in particular high-intensity chronic pain, is associated with an increased prevalence of cardiovascular risk factors and metabolic syndrome. The 10-year CHD risk score and metabolic syndrome correlate well with increased pain intensity, but not with widespread pain. Copyright © 2013 International Association for the Study of Pain.

BKP and CKP revisited: the odd KP system

Dimakis, Aristophanes; Müller-Hoissen, Folkert

2009-01-01

By restricting a linear system for the KP hierarchy to those independent variables t n with odd n, its compatibility (Zakharov-Shabat conditions) leads to the 'odd KP hierarchy'. The latter consists of pairs of equations for two dependent variables, taking values in an (typically noncommutative) associative algebra. If the algebra is commutative, the odd KP hierarchy is known to admit reductions to the BKP and the CKP hierarchy. We approach the odd KP hierarchy and its relation to BKP and CKP in different ways, and address the question of whether noncommutative versions of the BKP and the CKP equation (and some of their reductions) exist. In particular, we derive a functional representation of a linear system for the odd KP hierarchy, which in the commutative case produces functional representations of the BKP and CKP hierarchies in terms of a tau function. Furthermore, we consider a functional representation of the KP hierarchy that involves a second (auxiliary) dependent variable and features the odd KP hierarchy directly as a subhierarchy. A method to generate large classes of exact solutions to the KP hierarchy from solutions to a linear matrix ODE system, via a hierarchy of matrix Riccati equations, then also applies to the odd KP hierarchy, and this in turn can be exploited, in particular, to obtain solutions to the BKP and CKP hierarchies

To determine the prevalence of hypertension and diabetes in residents of districts in metropolitan Lima and Callao, Peru. This was a cross-sectional study conducted during September 2006 in people aged 15 years and older, residing in metropolitan Lima and Callao. Participants were selected using a sample of “conglomerados” (neighborhoods) in three stages. Standardized procedures were used to measure weight, height, waist circumference, blood pressure and blood glucose levels. Univariate, bivariate and logistic regression analysis were performed to estimate odds ratios (OR) and their respective confidence intervals at 95%. We enrolled 1,771 subjects; the mean age was 39.5 ± 16.5 years. 62% were women. 19.5% (95% CI 17.6-21.4) were obese, 15.8% (95% CI 14.1-17.6) had hypertension and 3.9% (95% CI: 3.0-4.8) had diabetes. Obesity was associated with a greater likelihood of having hypertension (OR 2.15, 95% CI 1.57-2.94) and diabetes (OR 1.97, 95% CI 1.02-3.80). . The results of this study in a representative sample of residents in Lima and Callao showed high prevalences of hypertension and obesity and a moderate prevalence of diabetes. These results can be used as a reference for public health interventions and to monitor their impact.

To compare the prevalence of pulp calcification with that of carotid calcification using digital panoramic dental radiographs. Digital panoramic radiographs of patients at a dental oncology clinic were included if (1) the carotid artery bifurcation region was visible bilaterally and (2) the patient had non-restored or minimally restored molars and/or canines. An endodontist evaluated the images for pulpal calcifications in the selected teeth. An oral and maxillofacial radiologist independently evaluated the same images for calcifications in the carotid bifurcation region. Odds-ratio and Pearson χ 2 were used for data analysis. Presence of pulpal calcification was also evaluated as a screening test for the presence of carotid calcification. A total of 247 panoramic radiographs were evaluated. 32% (n=80) had pulpal calcifications and 25% (n=61) had carotid calcifications with 12% (n=29) having both carotid and pulp calcifications. A significantly higher prevalence of both pulp and carotid calcification was found in subjects older than age 60 years compared to younger age groups. Accuracy of pulpal calcification in screening for carotid calcification was 66.4%. Both pulp and carotid calcifications were more prevalent in older individuals. The presence of pulp calcification was not a strong predictor for the presence of carotid calcification. (orig.)

Our study evaluated the lifetime prevalence of and risk factors for suicidal ideation and suicide attempts in Jeollabuk-do Province, Korea. Participants were selected from the population of individuals aged 13-100 years living Jeollabuk-do Province, Korea. A total of 2,964 subjects provided information about lifetime suicidal behavior and sociodemographic and psychological characteristics, completing the Zung Depression Scale, the Scale for Suicidal Ideation, the Multidimensional Anger Inventory, and the Rosenberg Self-Esteem Scale. The lifetime prevalence of suicidal ideation and suicide attempts, 24.8% and 6.2%, respectively, were higher than in previous studies. Multivariate regression revealed that family harmony had the highest odds ratio of all variables, including psychological factors. Along with depression and self-esteem, anger--which is the basic symptom of the Korean culture-related anger syndrome, Hwa-byung--was significantly associated with lifetime suicidal behavior. Lifetime suicidal behavior was highly prevalent in Jeollabuk-do Province. The most significant risk factors were found to be social support, family disharmony, anger, depression, and low self-esteem in Koreans.

Many studies have reported a higher prevalence of Attention-Deficit/Hyperactivity Disorder (ADHD) among disadvantaged populations, but few have considered how parental history of ADHD might modify that relationship. We evaluated whether the prevalence of ADHD varies by socioeconomic status (SES) and parental history of ADHD in a population-sample of elementary school children age 6-14 years. We screened all children in grades 1-5 in 17 schools in one North Carolina (U.S.) county for ADHD using teacher rating scales and 1,160 parent interviews, including an ADHD structured interview (DISC). We combined parent and teacher ratings to determine DSM-IV ADHD status. Data analysis was restricted to 967 children with information about parental history of ADHD. SES was measured by family income and respondent education. We found an interaction between family income and parental history of ADHD diagnosis (p = .016). The SES gradient was stronger in families without a parental history and weaker among children with a parental history. Among children without a parental history of ADHD diagnosis, low income children had 6.2 times the odds of ADHD (95% CI 3.4-11.3) as high income children after adjusting for covariates. Among children with a parental history, all had over 10 times the odds of ADHD as high income children without a parental history but the SES gradient between high and low income children was less pronounced [odds ratio (OR) = 1.4, 95% CI 0.6-3.5]. Socioeconomic status and parental history of ADHD are each strong risk factors for ADHD that interact to determine prevalence. More research is needed to dissect the components of SES that contribute to risk of ADHD. Future ADHD research should evaluate whether the strength of other environmental risk factors vary by parental history. Early identification and interventions for children with low SES or parental histories of ADHD should be explored. © 2017 Association for Child and Adolescent Mental Health.

Nitric oxide and its metabolites, nitrate and nitrite, are important regulators linked to various diseases. We studied the association of fasting serum concentrations of nitrate and nitrite, combined as NOx, without special diet, with the prevalence of various chronic diseases. Fasting concentrations of NOx were assayed in a cohort of 1087 patients recruited to Stress Aging and Health in Russia study that represents male and female population in Moscow, Russia, over 55 years of age. Chronic diseases were recorded based on anamnesis and additional assays were run to characterize immune status and lipid and carbohydrate metabolism. Odds ratios were calculated to associate NOx concentrations with prevalence of chronic diseases in pooled deciles below or above borderline. NOx over 44.7 µM were associated with increased prevalence of various chronic diseases such as diabetes type II, hyperthyroidism, coronary heart disease, gout and thrombosis/stroke. NOx 65.3 µM and above were associated with lowered prevalence of osteoporosis. NOx levels of 74.6 µM and above were associated with significantly higher number of patients who abstain from consumption of alcoholic beverages. NOx were not associated with cancer. Thus, fasting concentrations of NOx in serum can be an important diagnostic parameter characteristic for specific chronic diseases.

Avascular necrosis (AVN) has been reported in systemic lupus erythematosus (SLE) and most SLE patients suffer from this problem. To study the prevalence of AVN in Thai SLE patients and to determine the risk factors for developing AVN. A retrospective study was performed, between January 1, 1995 and August 31, 2005, on patients over 15 years of age in Khon Kaen, Thailand. The medical records of 736 SLE patients were reviewed. The female to male ratio was 15.4:1. The prevalence of AVN was 8.8%. The average age at the time of AVN detection was 27 years (range, 18-54) and the average duration of disease 69 months (range, 12-112). All cases were AVN of the hip joint. The factors correlated with AVN included: long duration of disease, history of previous septic arthritis in the ipsilateral hip to the AVN development, hematological involvement, gastrointestinal involvement, arthritis and cutaneous vasculitis. After regression analysis, hematological involvement and long duration of disease were associated with AVN with a respective odds ratio of 3.13 (95% CI 1.13-8.54) and 1.01 (95% CI 1.00-1.02). Neither high-dose steroid nor antimalarial treatment were correlated with AVN in our study and 4.6% (n = 3) of patients had never received steroid therapy during the follow-up period. Prevalence of symptomatic AVN was 8.8% in our SLE patients. A longer duration of disease and hematological involvement were associated with AVN development.

Full Text Available BACKGROUND: The screening of hospital admission patients for methicillin resistant Staphylococcus aureus (MRSA is of undisputed value in controlling and reducing the overall MRSA burden; yet, a concerted parallel universal screening intervention throughout all hospitals of an entire German Federal State has not yet been performed. METHODOLOGY/PRINCIPAL FINDINGS: During a four-week period, all 24 acute care hospitals of the State of Saarland participated in admission prevalence screening. Overall, 436/20,027 screened patients revealed MRSA carrier status (prevalence, 2.2/100 patients with geriatrics and intensive care departments associated with highest prevalence (7.6/100 and 6.3/100, respectively. Risk factor analysis among 17,975 admission patients yielded MRSA history (OR, 4.3; CI₉₅ 2.7-6.8, a skin condition (OR, 3.2; CI₉₅ 2.1-5.0, and/or an indwelling catheter (OR, 2.2; CI₉₅ 1.4-3.5 among the leading risks. Hierarchical risk factor ascertainment of the six risk factors associated with highest odd's ratios would require 31% of patients to be laboratory screened to allow for detection of 67% of all MRSA positive admission patients in the State. CONCLUSIONS/SIGNIFICANCE: State-wide admission prevalence screening in conjunction with risk factor ascertainment yields important information on the distribution of the MRSA burden for hospitals, and allows for data-based decisions on local or institutional MRSA screening policies considering risk factor prevalence and expected MRSA identification rates.

The prevalence of overweight and obesity in children in Mexico are high, as well as the complications associated with their presence. The objective of this work was to estimate the prevalence of metabolic syndrome in obese children and adolescents attending a Hospital Clinic and identify the associated factors. Cross sectional design with 120 children and adolescents; of either sex, with exogenous obesity and BMI > 2.0 standard deviations. Personal and family history was collected, blood pressure was measured and determination of serum glucose, insulin, lipoprotein HDL cholesterol and triglycerides were performed. The presence of metabolic syndrome with the ATPIII, WHO and International Diabetes Federation criteria was identified. The association of metabolic syndrome with different variables was identified with chi square test and calculation of odds ratio. Mean age was 10.6 ± 2.7 years. The prevalence of metabolic syndrome was 37.5% to 54.5% depending on the criteria used. The presence of metabolic syndrome was associated with a history of large birth weight (OR= 2.21 [1.01-4.82]), and insulin resistance (OR= 6.53 [2.40-18.2]). The prevalence of metabolic syndrome is high in this group of children and adolescents with obesity. The history of large birth weight and the presence of insulin resistance should alert us to the presence of the disease.

Objectives The present study aimed to investigate the prevalence and correlates of dental caries in elderly population in northeast China. Methods A community-based, cross-sectional study among 2376 elderly subjects (age: 65–74 years) from nine urban areas and nine rural areas in three provinces of northeast China was conducted using multistage stratified random sampling per the World Health Organization oral health survey methodology. Decayed-missing-filled teeth (DMFT) and decayed-filled teeth (DFT) indices were used to evaluate the prevalence of dental caries. Face-to-face questionnaire survey on oral health was performed in a randomly selected subset (n = 1197). T test and chi square test were employed to compare groups for continuous and categorical variables, respectively. Multivariate logistic regression was used to estimate odds ratios (ORs) and corresponding confidence intervals (CIs). Results 67.5% of elderly subjects reported dental caries (average DFT = 2.68±3.40), and the prevalence was higher in urban areas (Pcaries accounted for 2.08% with a rate higher in urban areas (Pdental insurance (OR 2.050; 95% CI 1.120–3.754) with dental caries. Conclusions The prevalence of dental caries in the elderly population in northeast China is high. The elderly from urban areas who smoke and who do not have a dental insurance are at a higher risk to develop dental caries. PMID:24260129

The purpose was to evaluate the prevalence and location of simultaneous fracture using bone scans in patients with hip fracture and to determine the risk factors associated with simultaneous fracture. One hundred eighty two patients with hip fracture were reviewed for this study. Clinical parameters and bone mineral density (BMD) of the lumbar vertebra and femoral neck were investigated. To identify acute simultaneous fracture, a bone scan was performed at 15.4±4.1days after hip fracture. The prevalence and location of simultaneous fracture were evaluated, and multivariate logistic regression analysis was performed to determine the risk factors. Simultaneous fracture was observed in 102 of 182 patients, a prevalence of 56.0%. Rib fracture was the most common type of simultaneous fracture followed by rib with vertebral fracture. The BMD of the lumbar vertebra was significantly lower in patients with simultaneous fracture (p=0.044) and was identified as an independent risk factor (odds ratio: OR 0.05, 95% confidence interval: CI 0.01-0.57). The prevalence of simultaneous fracture was relatively high among patients with hip fracture, and BMD was significantly lower in patients with simultaneous fracture than in patients without it. Surgeons should be aware of the possibility of simultaneous fracture in patients with hip fracture. Copyright © 2016 Elsevier Ltd. All rights reserved.

Water hardness has been associated with atopic eczema (AE) prevalence in two epidemiologic studies carried out on schoolchildren in England and Japan. To estimate the association between the prevalence of AE and domestic water hardness. The prevalence of AE was obtained from The International Study of Asthma and Allergies in Childhood, carried out in six towns in the province of Castellón on schoolchildren 6-7 and 13-14 years of age, using a standard questionnaire in 2002. Three zones were defined according to domestic water hardness of the six study localities: 300 mg/l. A logistic regression analysis was performed. The lifetime prevalence of AE in schoolchildren 6-7 years of age was higher with the increment of water hardness, 28.6, 30.5 and 36.5% respectively for each zone; between zone 1 and zone 3, the adjusted odds ratios (ORa) were 1.58 (95% Confidence Intervals [CI] 1.04-2.39) (adjusted tendency test p=0.034). Prevalence of symptoms of AE within the past year were 4.7, 4.5, and 10.4%, respectively by zone; between zone 1 and zone 3, the ORa was 2.29 (95% CI 1.19-4.42) (adjusted tendency test p=0,163). For 13-14 year-old schoolchildren, tendencies to lifetime prevalence of AE at any time or in the past year were not significant. This study suggests that in 6-7 year-old schoolchildren, water hardness in the area where they live has some relevance to the development of the disease.

Full Text Available Background: Reports suggest that the prevalence of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA has increased, and that CA-MRSA is more virulent than healthcare-associated (HA-MRSA. Aims: The aim of this study is to gain a better understanding of the invasiveness and prevalence of CA-MRSA in patients; we systematically reviewed the literature by conducting a meta-analysis. Materials and Methods: We searched the MEDLINE and PUBMED databases from the year these databases were established to January 2013. Results: The pooled CA-MRSA prevalence among 50,737 patients from 33 studies was 39.0% (range, 30.8-47.8%. The pooled CA-MRSA prevalence rates among pediatric and adult patients with MRSA infection were 50.2% (range, 37.5-62.8% and 42.3% (range, 16.4-73.3%, respectively. The pooled CA-MRSA prevalence rates of MRSA-infected patients in Asia, Europe, and North America were 23.1% (range, 12.0-39.8%, 37.4% (range, 21.1-56.4%, and 47.4% (range, 35.8-59.4%, respectively. Using the random effects model, we determined that the pooled odds ratio of invasive infections in CA- and HA-MRSA was 0.30 (95% confidence interval: 0.08-1.10; P = 0.07, test for heterogeneity P < 0.00001. Conclusions: The prevalence of CA-MRSA in MRSA infection varied with area and population. No difference in the ability to cause invasive infections was found between CA- and HA-MRSA. This finding challenges the view that CA-MRSA is more virulent than HA-MRSA.

Full Text Available Various theories predict the possible existence of T-odd and P-odd shortrange forces between spin ½ fermions, proportional to S・r where S is the fermion spin and r is the separation between particles. We use ensembles of polarized nuclei and an un-polarized mass to search for such a force over sub-mm ranges. We established an improved upper bound on the product gsgpn of the scalar coupling to particles in the un-polarized mass and the pseudo-scalar coupling of polarized neutrons for force ranges from 10−4 to 10−2 m, corresponding to a mass range of 2・10−3 to 2・10−5 eV for the exchange boson [1].

ói, state of Rio de Janeiro, Brazil, from 2003 to 2004. RESULTS: Thirty nine (8.6% presented prehypertension (PH and 13.4%, elevated pulse pressure (PP. At bivariate analysis, PH was significantly associated with sex, age and obesity, with more prevalent in boys aged between 15 and 17 years, and in the obese. Elevated PP was associated with gender only, as it was more prevalent in boys. Sexual maturation did not show an association with PH or elevated PP. Similar correlations were found at logistic regression. PH prevalence odds ratio was 7.7 for sex, 4.3 for age and 4.6 for obesity. Elevated PP prevalence odds ratio was 10.8 for sex. The correlation between PP and physical activity was positive and significant. The elevation of PP was attributable to systolic blood pressure. CONCLUSION: PH and the elevated PP were shown to be present in adolescents from a population with a low prevalence of hypertension, mostly in boys. Further prospective studies are necessary to assess the persistence and the impact of those conditions.

Full Text Available Background: This study was designed to determine the prevalence and assess the risk factors responsible for platelet transfusion refractoriness in hemato-oncological patients. Materials and Methods: The study included 30 patients. Twelve were clinically diagnosed as aplastic anemia and the 18 were of acute myeloid leukemia. A prospective 3 months follow-up was planned to monitor the response of platelet transfusion therapy, based on their posttransfusion corrected count increment at 1 st and 24 th h. Based on the observations, patients were categorized into refractory and nonrefractory groups. Common nonimmunological causes such as fever, sepsis, bleeding, disseminated intravascular coagulation, chemotherapy, splenomegaly, ABO mismatch, and antithymocyte globulin therapy were monitored. Among the immunological causes, presence of antihuman leukocyte antigen (HLA class I antibodies and platelet glycoprotein antibodies in patient′s serum were monitored. Results: During the study period, 17 (56.66% patients did not show desired platelet count increment. Transfusion requirements of refractory group for both red cell and platelet product were significantly higher (P < 0.05 in comparison to nonrefractory group. Among immunological causes, anti HLA class I antibodies (P < 0.013, antihuman platelet antigen-5b antibodies (P < 0.033 were significantly associated with refractoriness. Among nonimmunological causes, bleeding (P < 0.019, odd ratio 8.7, fever (P < 0.08, odd ratio 5.2, and infection (P < 0.07, odd ratio 5.4 were found to associated with refractoriness. Conclusion: Platelet refractoriness should be suspected in multitransfused patients not showing expected increment in platelet counts and thoroughly investigated to frame further guidelines in order to ensure proper management of these kind of patients.

To evaluate the prevalence of high risk of psychiatric morbidity in the Spanish adult population and its changes between 2006 and 2012. Data from 47,905 participants obtained from the National Health Surveys in 2006 and 2012 were used. Mental health status was assessed with the General Health Questionnaire score. Adjusted logistic regression models were fitted. The prevalence of high risk of psychiatric morbidity was 20.5% in 2012 and 21.3% in 2006. Using 2006 as the reference, the odds ratio (OR) for these problems in 2012 was 0.84 (0.79-0.89) in women and 1.10 (1.02-1.18) in men. In women, it decreased for all ages. In men, these ORs were 1.15 (1.04-1.27) in the aged 16-44 group, 1.23 (1.08-1.40) in the aged 45-64 group and 0.81 (0.68-0.96) in the aged ≥ 65 group. The prevalence of high risk of psychiatric morbidity decreased except in males <65 years of age, who are more sensitive to the economic crisis. Copyright © 2017 SESPAS.

Full Text Available Dingus and colleagues (Proc. Nat. Acad. Sci. U.S.A. 2016, 113, 2636–2641 reported a crash odds ratio (OR estimate of 2.2 with a 95% confidence interval (CI from 1.6 to 3.1 for hand-held cell phone conversation (hereafter, “Talk” in the SHRP 2 naturalistic driving database. This estimate is substantially higher than the effect sizes near one in prior real-world and naturalistic driving studies of conversation on wireless cellular devices (whether hand-held, hands-free portable, or hands-free integrated. Two upward biases were discovered in the Dingus study. First, it selected many Talk-exposed drivers who simultaneously performed additional secondary tasks besides Talk but selected Talk-unexposed drivers with no secondary tasks. This “selection bias” was removed by: (1 filtering out records with additional tasks from the Talk-exposed group; or (2 adding records with other tasks to the Talk-unexposed group. Second, it included records with driver behavior errors, a confounding bias that was also removed by filtering out such records. After removing both biases, the Talk OR point estimates declined to below 1, now consistent with prior studies. Pooling the adjusted SHRP 2 Talk OR estimates with prior study effect size estimates to improve precision, the population effect size for wireless cellular conversation while driving is estimated as 0.72 (CI 0.60–0.88.

The chiral-odd transversity generalized parton distributions of the nucleon can be accessed experimentally through the exclusive photoproduction process {gamma} + N {yields} {pi} + {rho} + N', in the kinematics where the meson pair has a large invariant mass and the final nucleon has a small transverse momentum, provided the vector meson is produced in a transversally polarized state. Estimated counting rates show that the experiment is feasible with real or quasi real photon beams expected at JLab at 12 GeV and in the COMPASS experiment. (Phys Letters B688,154,2010) In addition, a consistent classification of the chiral-odd pion GPDs beyond the leading twist 2 is presented. Based on QCD equations of motion and on the invariance under rotation on the light-cone of any scattering amplitude involving such GPDs, we reduce the basis of these chiral-odd GPDs to a minimal set.

Although the prevalence of oral clefts in China is among the highest worldwide, little is known about the prevalence of speech disability associated with cleft palate in Chinese children. The data for this study were collected from the Second China National Sample Survey on Disability, and identification of speech disability associated with cleft palate was based on consensus manuals. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). A weighted number of 112,070 disabled children affected by cleft palate were identified, yielding a prevalence of 3.45 per 10,000 children (95% CI: 3.19–3.71). A history of speech disability in the mother (OR = 20.266, 95% CI 5.788–70.959, p cleft palate in the offspring. Our results showed that maternal speech disability, older paternal child-bearing age, and lower levels of parental education were independent risk factors for speech disability associated with cleft palate for children in China. These findings may have important implications for health disparities and prevention. PMID:27886104

Corporal punishment is closely related to physical abuse of children and is associated with several negative characteristics and experiences in children and youths. This study examined the relative unique contribution of 6 variables (social support, socioeconomic status, depression, self-efficacy, knowledge of child development, and history of postpartum depression) to maternal corporal punishment of children. A sample of 76 mothers was dichotomized into those who never spanked or hit with an object and those who have spanked or hit with an object. The mothers were recruited from a community mental health agency, an urban community center, and a court of common pleas. The measures in the present study were administered prior to mothers' participation in a parent training program. Mothers referred by the court of common pleas were mandated to participate in the parent training program, and the mothers from the community mental health agency and the urban community center volunteered to participate in the parent training program. However, all participants voluntarily completed the research measures. Binary logistic regression identified postpartum depression as the only variable to significantly increase the odds of corporal punishment (odds ratio = 6.307, 95% confidence interval = 1.098-36.214, p = .039). The findings demonstrate increased odds of corporal punishment among a high-risk sample of women with postpartum depression. The generalizability of these findings may be limited to low socioeconomic class and White and African American mothers enrolled in parent-training programs.

To examine differences in lifetime prevalence of mental disorder and service use among U.S. adolescents by both immigrant generation and race/ethnicity. A total of 6,250 adolescents aged 13 to 18 years in the National Comorbidity Survey Replication Adolescent Supplement were assessed for lifetime prevalence of mood and/or anxiety disorders, behavior disorders, and mental health service use. Twelve groups defined by self-identified race/ethnicity (non-Hispanic white, Hispanic, non-Hispanic black, Asian) and immigrant generation (first, second, third, or more) were compared. Differences in prevalence of lifetime mental disorder were most apparent when immigrant generation and race/ethnicity were considered jointly. Compared to third+generation non-Hispanic white adolescents, the odds of mood/anxiety disorder were increased among second-generation Asian (adjusted odds ratio [AOR] = 2.51; 95% CI = 1.22-5.17) and third+generation Hispanic (AOR = 1.28; 95% CI = 1.00-1.63) but reduced among first-generation Asian (AOR = 0.27; 95% CI = 0.10-0.71) and second-generation non-Hispanic white adolescents (AOR = 0.50; 95% CI = 0.30-0.81). The odds of behavior disorder were lower among first-generation Asian (AOR = 0.26; 95% CI = 0.09-0.71) and all generations of non-Hispanic black adolescents (AOR range 0.43-0.55). Adjusting for lifetime disorder, first-generation Hispanic and non-Hispanic white adolescents and all generations of non-Hispanic black adolescents were less likely to receive mental health services (AOR range 0.24-0.55). Variation in risk of disorder by immigrant generation and race/ethnicity underscores the importance of considering social, economic, and cultural influences in etiologic and treatment studies of adolescent psychopathology. Lower rates of service use, particularly among first-generation immigrant adolescents, highlight the need to identify and address barriers to recognition and treatment of mental disorders among adolescents from immigrant

Hypertension is a health issue affecting adolescents. Accumulating evidence affirms that elevated blood pressure begins in childhood and tracks into adulthood. This cross-sectional study was conducted to determine the prevalence of elevated blood pressure and its predictors among secondary school students in Sarawak, Malaysia. A total of 2,461 secondary school students aged 12-17 years from 19 schools in Sarawak participated in the study. Questionnaire was used to obtain socio-demographic data, parental history of hypertension, and self-reported physical activity. Anthropometric and blood pressure measurements were taken. Data was entered and analysed using SPSS version 23.0. The prevalence of adolescents with elevated blood pressure, overweight, central obesity, and overfat were 30.1%, 24.3%, 13.5%, and 6.7%, respectively. Multivariate logistic regression demonstrated the predictors significantly associated with elevated blood pressure among respondents: overweight (adjusted odds ratio=3.144), being male (adjusted odds ratio=3.073), being Chinese (adjusted odds ratio=2.321) or Iban (adjusted odds ratio=1.578), central obesity (adjusted odds ratio=2.145), being overfat (adjusted odds ratio=1.885), and being an older adolescent (adjusted odds ratio=1.109). Parental history of hypertension, locality, and physical activity showed no significant associations. The obesity epidemic must be tackled at community and school levels by health education and regulation of school canteen foods. Copyright© by the National Institute of Public Health, Prague 2018.

Arterial hypertension is a major public health problem and has increased considerably in young individuals in past years. Thus, identifying factors associated with this condition is important to guide intervention strategies in this population. To determine high blood pressure prevalence and its associated factors in adolescents. A random sample of 1,242 students enrolled in public schools of the city of Curitiba (PR) was selected. Self-administered questionnaires provided family history of hypertension, daily energy expenditure, smoking habit, daily fat intake, and socioeconomic status. Waist circumference was measured following standardized procedures, and blood pressure was measured with appropriate cuffs in 2 consecutive days to confirm high blood pressure. Relative frequency and confidence interval (95%CI) indicated high blood pressure prevalence. Bivariate and multivariate analyses assessed the association of risk factors with high blood pressure. The high blood pressure prevalence was 18.2% (95%CI 15.2-21.6). Individuals whose both parents had hypertension [odds ratio (OR), 2.22; 95%CI 1.28-3.85] and those with high waist circumference (OR, 2.1; 95%CI 1.34-3.28) had higher chances to develop high blood pressure. Positive family history of hypertension and high waist circumference were associated with high blood pressure in adolescents. These factors are important to guide future interventions in this population.

Full Text Available Abstract Background: Arterial hypertension is a major public health problem and has increased considerably in young individuals in past years. Thus, identifying factors associated with this condition is important to guide intervention strategies in this population. Objective: To determine high blood pressure prevalence and its associated factors in adolescents. Methods: A random sample of 1,242 students enrolled in public schools of the city of Curitiba (PR was selected. Self-administered questionnaires provided family history of hypertension, daily energy expenditure, smoking habit, daily fat intake, and socioeconomic status. Waist circumference was measured following standardized procedures, and blood pressure was measured with appropriate cuffs in 2 consecutive days to confirm high blood pressure. Relative frequency and confidence interval (95%CI indicated high blood pressure prevalence. Bivariate and multivariate analyses assessed the association of risk factors with high blood pressure. Results: The high blood pressure prevalence was 18.2% (95%CI 15.2-21.6. Individuals whose both parents had hypertension [odds ratio (OR, 2.22; 95%CI 1.28-3.85] and those with high waist circumference (OR, 2.1; 95%CI 1.34-3.28 had higher chances to develop high blood pressure. Conclusion: Positive family history of hypertension and high waist circumference were associated with high blood pressure in adolescents. These factors are important to guide future interventions in this population.

While there is a plethora of research on the prevalence of individual chronic conditions, studies that examine the clustering of these conditions are lacking, especially among immigrant, minority groups. Cross-sectional, convenience sample. A self-administered survey was distributed at churches, mosques, and small businesses. Arabs (n = 1383), Chaldeans (n = 868), Blacks (n = 809) and Whites (n = 220) in southeast Michigan. We estimated the prevalence of hypertension, high cholesterol, heart disease, diabetes, asthma, and depression. Using a logistic regression model, we estimated odds ratios and 95% confidence intervals for the association between ethnicity and reporting one or more chronic conditions before and after adjusting for demographic, socioeconomic status, health care, chronic conditions, and health behavior variables. The overall age and sex-adjusted prevalence of having one or more chronic conditions was 44%. Estimates were lower for Chaldeans (32%) compared to Arabs (44%), Whites and Blacks (50% for each group). In the fully adjusted model, Chaldeans were less likely (OR = 0.62; 95% CI = 0.43-0.89) to report having one more chronic conditions compared to Whites. Future studies should employ probability samples, and should collect more detailed sociodemographic and acculturation data, which influence the relationship between race/ethnicity and the prevalence of chronic conditions.

Acne vulgaris has an important genetic predisposition, as well as keratosis pilaris. Clinical observations suggest that patients with keratosis pilaris have less frequent or less severe acne breakouts; however, we found no studies on this regard To determine if the presence of keratosis pilaris is associated with lower prevalence and severity of acne. A cross-sectional study was conducted with dermatology outpatients aged between 14 and 35 years. We evaluated history and clinical grade of acne, demographic variables, history of atopy, smoking, and use of hormonal contraceptives. Two groups were defined by the presence or absence of moderate to severe keratosis pilaris on the arms and were compared by bivariate analysis and by conditional multiple logistic regression. We included 158 patients (66% women), with a median age of 23 ± 11 years. Twenty-six percent of them had keratosis pilaris, which was associated with a history of atopy (odds ratio [OR]=2.80 [1.36 to 5.75]; pkeratosis pilaris had a less frequent history of acne (OR=0.32 [0.14 to 0.70]; pkeratosis pilaris on the arms was associated with lower prevalence of acne vulgaris and lower severity of facial lesions in adolescents and young adults.

Full Text Available BACKGROUND: Transmission of tuberculosis (TB to health care workers (HCWs is a global issue. Although effective infection control measures are expected to reduce nosocomial TB, HCWs' infection has not been assessed enough in TB high burden countries. We conducted a cross-sectional study to determine the prevalence of TB infection and its risk factors among HCWs in Hanoi, Viet Nam. METHODOLOGY/PRINCIPAL FINDINGS: A total of 300 HCWs including all staff members in a municipal TB referral hospital received an interferon-gamma release assay (IGRA, QuantiFERON-TB Gold In-Tube(TM, followed by one- and two-step tuberculin skin test (TST and a questionnaire-based interview. Agreement between the tests was evaluated by kappa statistics. Risk factors for TB infection were analyzed using a logistic regression model. Among the participants aged from 20 to 58 years (median = 40, prevalence of TB infection estimated by IGRA, one- and two-step TST was 47.3%, 61.1% and 66.3% respectively. Although the levels of overall agreement between IGRA and TST were moderate, the degree of agreement was low in the group with BCG history (kappa = 0.29. Working in TB hospital was associated with twofold increase in odds of TB infection estimated by IGRA. Increased age, low educational level and the high body mass index also demonstrated high odds ratios of IGRA positivity. CONCLUSIONS/SIGNIFICANCE: Prevalence of TB infection estimated by either IGRA or TST is high among HCWs in the hospital environment for TB care in Viet Nam and an infection control program should be reinforced. In communities with heterogeneous history of BCG vaccination, IGRA seems to estimate TB infection more accurately than any other criteria using TST.

To determine the prevalence of recurrent abdominal pain (RAP) among Malaysian school children aged from 11 to 16 years. A preliminary cross-sectional survey in which three urban schools and three rural schools were selected randomly. Two classes were selected randomly from each year. A questionnaire was given to each child asking him or her about whether they had experienced abdominal pain occurring at least three times over a period of at least 3 months, interfering with normal daily activity. 1 Interfering with normal daily activity was defined as missing school and/or having to stop doing a routine daily activity on account of the pain. Girls whose pains were related to periods were excluded. After the forms had been completed, each child was again interviewed to ensure that Apley's criteria1 was fulfilled in cases of RAP. The overall prevalence of RAP among 1549 schoolchildren (764 boys; 785 girls) was 10.2% (95% confidence interval (CI), 8.8-11.8). There appeared to be a higher prevalence in rural schoolchildren (P = 0.008; odds ratio (OR) 1.58), in those with a lower family income (P family size. : In spite of differences in time and culture, the overall prevalence of 10.2% found in this study is similar to that determined by Apley.1 There are significant differences in the prevalence of RAP between children from rural and urban schools, among children with different family incomes and among children whose parents have different educational backgrounds.

The low-lying states in the odd-odd and unstable isotopes {sup 106,108}In have been Coulomb excited from the ground state and the first excited isomeric state at the REX-ISOLDE facility at CERN. With the additional data provided here the {pi}g{sub 9/2}{sup -1} x {nu}d{sub 5/2} and {pi}g{sub 9/2}{sup -1} x {nu} g{sub 7/2} multiplets have been re-analyzed and are modified compared to previous results. The observed {gamma} -ray de-excitation patterns were interpreted within a shell model calculation based on a realistic effective interaction. The agreement between theory and experiment is satisfactory and the calculations reproduce the observed differences in the excitation pattern of the two isotopes. The calculations exclude a 6{sup +} ground state in {sup 106}In. This is in agreement with the conclusions drawn using other techniques. Furthermore, based on the experimental results, it is also concluded that the ordering of the isomeric and ground state in {sup 108}In is inverted compared to the shell model prediction. Limits on B(E2) values have been extracted where possible. A previously unknown low-lying state at 367keV in {sup 106}In is also reported. (orig.)

Distributional justice in Swedish wind power development – An odds ratio analysis of windmill localization and local residents’ socio-economic characteristics

Liljenfeldt, Johanna; Pettersson, Örjan

2017-01-01

With a fast rise in large-scale wind power development in Sweden and other countries in recent years, issues related to energy justice generally and distributional justice specifically have become concerns in windmill siting. Some research, for instance, has indicated that it is easier to build windmills in economically marginalized communities. The evidence for this, however, is still limited. Thus, this study aims to statistically evaluate the extent to which the decisions to approve or reject windmill proposals in Sweden can be explained by factors related to the socio-economic characteristics of people living in the areas surrounding windmill sites. The study is based on an odds ratio analysis of decisions on all windmill proposals in Sweden, in which geo-referenced socio-economic data on an individual level for all inhabitants within 3 and 10 km of the windmill sites are studied. The results show skewness in the distribution of windmills, with a higher likelihood of rejection in areas with more highly educated people and people working in the private sector, compared to a higher likelihood of approval in areas with more unemployed people. This skewness, while not necessarily unjust, warrants further policy and research attention to distributional justice issues when developing wind power. - Highlights: • The distributional justice of windmill siting in Sweden is statistically evaluated. • Windmill siting decisions are related to people's socio-economic characteristics. • The results indicate some distributional skewness for wind power development. • The study gives statistical rigour and generalisability to energy justice findings. • The results warrant follow-ups and policy guides for how to handle benefit-sharing.

Constraints on a parity-even/time-reversal-odd interaction

Time-Reversal-Invariance non-conservation has for the first time been unequivocally demonstrated in a direct measurement, one of the results of the CPLEAR experiment. What is the situation then with regard to time-reversal-invariance non-conservation in systems other than the neutral kaon system? Two classes of tests of time-reversal-invariance need to be distinguished: the first one deals with parity violating (P-odd)/time-reversal-invariance non-conserving (T-odd) interactions, while the second one deals with P-even/T-odd interactions (assuming CPT conservation this implies C-conjugation non-conservation). Limits on a P-odd/T-odd interaction follow from measurements of the electric dipole moment of the neutron. This in turn provides a limit on a P-odd/T-odd pion-nucleon coupling constant which is 10 -4 times the weak interaction strength. Limits on a P-even/T-odd interaction are much less stringent. The better constraint stems also from the measurement of the electric dipole moment of the neutron. Of all the other tests, measurements of charge-symmetry breaking in neutron-proton elastic scattering provide the next better constraint. The latter experiments were performed at TRIUMF (at 477 and 347 MeV) and at IUCF (at 183 MeV). Weak decay experiments (the transverse polarization of the muon in K + →π 0 μ + ν μ and the transverse polarization of the positrons in polarized muon decay) have the potential to provide comparable or possibly better constraints

Full Text Available This research aims to examine the socio-economic correlates of anemia in women, and potential sources of iron in household diets in Afghanistan. It also examines whether ownership of agricultural (particularly livestock assets and their use in food production has a role in alleviating anaemia, especially where local markets may be inadequate. We analyse data from the 2010/11 Afghanistan Multiple Indicator Cluster Survey, estimating a logistic regression to examine how anemia status of women is associated with socio-economic covariates. A key result found is that sheep ownership has a protective effect in reducing anemia (prevalence odds ratio of sheep ownership on anemia of 0.83, 95% confidence interval (CI: 0.73-0.94 after controlling for wealth and other covariates. This association is found to be robust to alternative model specifications. Given the central role of red meat in heme iron provision and absorption of non-heme iron, we hypothesise that sheep ownership promotes mutton consumption from own-production in a setting where market-sourced provision of nutritious food is a challenge. We then use the 2011/12 National Risk and Vulnerability Assessment household data to understand the Afghan diet from the perspective of dietary iron provision, and to understand interactions between own-production, market sourcing and mutton consumption. Sheep ownership is found to increase the likelihood that a household consumed mutton (odds ratio of 1.27, 95% CI: 1.15-1.42, the number of days in the week that mutton was consumed (prevalence rate ratio of 1.24. 95% CI: 1.12-1.37 and the quantity of mutton consumed (7 grams/person/week. In the subsample of mutton consumers, households sourcing mutton mostly from own production consumed mutton 1.5 days more frequently on average than households relying on market purchase, resulting in 100 grams per person per week higher mutton intake.

The goal of the study was to assess public school children at the end of the first stage of elementary school. We used a protocol applied concurrently with a writing test in the form of an unexpected activity in 28 public schools; 2,893 children assessed, 687 exhibited performance below 58 points, 184 were excluded due to change of address or lack of consent; 503 children subjected to a test of intellectual capacity and reading assessment and 71 considered intellectually disabled were excluded. 226 (7.8%) children, who could read, write, and had normal intellectual level, met the criteria of developmental dyscalculia (DD), 98 female and 128 male. The most influential factors in the prevalence were socioeconomic levels of the schools neighborhood, education level of parents, and being male, as demonstrated by the odds ratio and multiple logistic regression analysis. Further studies should be done so that educational policies are taken.

By a cross-sectional epidemiology study, we attempted to correlate the consumption of tea and/or health supplements, living habits and socio-demographic factors to the prevalence of hypertension among Singaporean Chinese residents. Singaporean Chinese residents aged ⩾40 years were randomly selected and interviewed face-to-face by clinical research assistants. Hypertension was defined as measured systolic blood pressure at least 140 mm Hg and/or diastolic blood pressure at least 90  mmHg or self-reported history/treatment for hypertension. The prevalence of hypertension among the whole investigated population (N=1184, 58.27% females) was 49.73% and the prevalence increased to 66.47% in the sub-population aged ⩾60 years. High risk of hypertension was associated with age ⩾60 years (odds ratio (OR): 4.15-4.19, P25 kg m(-2), OR: 2.10-2.11, Pcoffee intake (OR: 1.44-1.46, Pcoffee could be a risk factor of hypertension. These findings may provide useful information for health promotion to reduce risk of hypertension and warrant further study to confirm and elucidate such association.

Although the notion of healthy aging has gained wide acceptance in gerontology, measuring the phenomenon is challenging. Guided by a prominent conceptualization of healthy aging, we examined how shifting from a more to less stringent definition of healthy aging influences prevalence estimates, demographic patterns, and validity. Data are from adults aged 65 years and older who participated in the Health and Retirement Study. We examined four operational definitions of healthy aging. For each, we calculated prevalence estimates and examined the odds of healthy aging by age, education, gender, and race-ethnicity in 2006. We also examined the association between healthy aging and both self-rated health and death. Across definitions, the prevalence of healthy aging ranged from 3.3% to 35.5%. For all definitions, those classified as experiencing healthy aging had lower odds of fair or poor self-rated health and death over an 8-year period. The odds of being classified as "healthy" were lower among those of advanced age, those with less education, and women than for their corresponding counterparts across all definitions. Moving across the conceptual continuum--from a more to less rigid definition of healthy aging--markedly increases the measured prevalence of healthy aging. Importantly, results suggest that all examined definitions identified a subgroup of older adults who had substantially lower odds of reporting fair or poor health and dying over an 8-year period, providing evidence of the validity of our definitions. Conceptualizations that emphasize symptomatic disease and functional health may be particularly useful for public health purposes.

2017-09-01

We applied the gross theory of β-decay to calculate the reactor antineutrino (νe) spectra emitted from 235,238U and 239,241Pu samples under neutron irradiation by summing up all the contributions from a large number of decaying fission-products (FPs). Considering the special role of the odd(Z)-odd(N) FPs in spectrum-shaping, we utilized the experimentally-known spin-parity of each odd-odd FP through the treatment proposed by Nakata, Tachibana and Yamada. Owing to this treatment, the consistency between calculated and experimental spectra was remarkably improved in a way expected from the nature of the gross theory of β-decay.

Depression and anxiety in the antenatal period are of public health concern given potential adverse effects for both mother and infant. Both are under-researched in the first trimester of pregnancy, especially in Africa. We examine the prevalence of first trimester antenatal depression and anxiety in a cohort of South African women and investigate associated risk factors. Data were collected from 946 women (2014-2016) in the Soweto First 1000 Days Cohort, a prospective pregnancy cohort in Soweto, South Africa. Antenatal depression was assessed using the Edinburgh Postnatal Depression Scale with a score of ⩾13 indicating probable depression. Anxiety was assessed using the short form of the State-Trait Anxiety Index with a score ⩾12 indicating probable anxiety. Prevalence of antenatal depression was 27% [95% confidence interval (CI) 24.2-29.8] and anxiety 15.2% (95% CI 12.9-17.5). Factors associated with antenatal depression and anxiety were predominantly relationship- and family-centred. Women who perceived that their partner made life harder for them had three-fold increased odds for depression [(odds ratio (OR) 3.33 [2.28-4.85] P<0.001], whereas those with family stressors had almost double the odds for depression (OR 1.78 [1.22-2.59] P=0.003) and anxiety (OR 1.75 [1.44-2.69] P=0.0011). Antenatal depression and anxiety are common in the first trimester of pregnancy, and partner and family relationship stressors are central. Longitudinal analysis is needed to determine if this is a phase of adjustment to pregnancy or onset of persistent symptomology. Early intervention may have secondary preventative effects and should involve the partner and family.

Gastroesophageal reflux disease (GERD) is typically diagnosed based on symptoms of regurgitation and heartburn, although it may also manifest as asthma-like symptoms, laryngitis, or dental erosion. The purpose of this prospective, cross-sectional study was to assess the prevalence of dental erosion in people with GERD and to evaluate the association between GERD and dental erosion. The presence, severity, and pattern of dental erosion was assessed in 51 participants with GERD and 50 participants without GERD using the Smith and Knight tooth wear index. Medical, dietary, and dental histories were collected by questionnaire. Factors potentially related to dental erosion, including GERD, were evaluated by logistic regression. Dental erosion was observed in 31 (60.8%) participants with GERD and 14 (28%) participants without GERD. Bivariate analysis revealed that participants with GERD were more likely to experience dental erosion (crude odds ratio [cOR]: 2.74; 95% CI: 1.19, 6.32) than participants without GERD. Multivariate analysis also revealed that participants with GERD had a higher risk of dental erosion (adjusted odds ratio [aOR]: 3.97; 95% CI: 1.45, 10.89). Consumption of grains and legumes, the most frequently consumed foods in China, did not correlate with dental erosion. However, carbonated beverage consumption was significantly associated with GERD and dental erosion (aOR: 3.34; 95% CI: 1.01, 11.04; P=.04). GERD was positively correlated with dental erosion. Carbonated beverage consumption can increase the risk of both GERD and dental erosion. Copyright © 2016 Editorial Council for the Journal of Prosthetic Dentistry. Published by Elsevier Inc.

The aim of this cross-sectional study was to estimate the prevalence of hypertension among adults (n = 841) in communities along the Madeira River in the Brazilian Amazon, prior to startup of the Santo Antônio Hydroelectric Plant. The study gathered information on sociodemographic conditions, history of diseases, habits, fish consumption, and anthropometric parameters. Logistic regression was used to calculate odds ratios and the respective confidence intervals. Among the riverine communities, 26% (95%CI: 23%-29%) of adults presented hypertension (29% in men [95%CI: 24%-33%] and 23% in women [95%CI: 19%-27%]). Factors associated with hypertension were age, BMI, and place of residence in men and age, triglycerides, and blood glucose in women. The findings can contribute to strategies for state and municipal health services to monitor and prevent cardiovascular events.

Full Text Available The objective of this research was to determine the prevalence, risk factors and consequent effect of dystocia on lactation performance in Holstein dairy cows in Iran. The data set consisted of 55,577 calving records on 30,879 Holstein cows in 30 dairy herds for the period March 2000 to April 2009. Factors affecting dystocia were analyzed using multivariable logistic regression models through the maximum likelihood method in the GENMOD procedure. The effect of dystocia on lactation performance and factors affecting calf birth weight were analyzed using mixed linear model in the MIXED procedure. The average incidence of dystocia was 10.8% and the mean (SD calf birth weight was 42.13 (5.42 kg. Primiparous cows had calves with lower body weight and were more likely to require assistance at parturition (p<0.05.

Studies investigating the prevalence of positive mental health and its correlates are still scarce compared to the studies on mental disorders, although there is growing interest of assessing positive mental health in adolescents. So far, no other study examining the prevalence and determinants of positive mental health in Chinese adolescents has been found. The purpose of this study was to assess the prevalence and correlates of positive mental health in Chinese adolescents. This cross-sectional study used a questionnaire including Mental Health Continuum-Short Form (MHC-SF) and items regarding multiple aspects of adolescent life. The sample involved a total of 5399 students from grade 8 and 10 in Weifang, China. Multivariate Logistic regression analyses were performed to evaluate the associations between potential indicators regarding socio-economic situations, life style, social support and school life and positive mental health and calculate odds ratios and 95% confidence intervals. More than half (57.4%) of the participants were diagnosed as flourishing. The correlated factors of positive mental health in regression models included gender, perceived family economy, the occurrence of sibling(s), satisfaction of self-appearance, physical activity, sleep quality, stress, social trust, desire to learn, support from teachers and parents as well as whether being bullied at school (OR ranging from 1.23 to 2.75). The Hosmer-Lemeshow p-value for the final regression model (0.45) indicated adequate model fit. This study gives the first overview on prevalence and correlates of positive mental health in Chinese adolescents. The prevalence of positive mental health in Chinese adolescents is higher than reported in most of the previous studies also using MHC-SF. Our findings suggest that adolescents with advantageous socio-economic situations, life style, social support and school life are experiencing better positive mental health than others.

The objective of this study was to evaluate the effect of vaccination of breeder chickens on Salmonella prevalences and loads in breeder and broiler chicken flocks. Chickens housed on six commercial breeder farms were vaccinated with a killed Salmonella vaccine containing Salmonella Typhimurium, Salmonella Enteritidis, and Salmonella Kentucky. Unvaccinated breeders placed on six additional farms served as controls. Eggs from vaccinated and unvaccinated breeder flocks were kept separately in the hatchery, and the resulting chicks were used to populate 58 commercial broiler flock houses by using a pair-matched design. Vaccinated breeder flocks had significantly higher Salmonella-specific antibody titers than did the unvaccinated breeder flocks, although they did not differ significantly with respect to environmental Salmonella prevalences or loads. Broiler flocks that were the progeny of vaccinated breeders had significantly lower Salmonella prevalences and loads than broiler flocks that were the progeny of unvaccinated breeders. After adjusting for sample type and clustering at the farm level, the odds of detecting Salmonella in samples collected from broiler flocks originating from vaccinated breeders were 62% lower (odds ratio [95% confidence interval] = 0.38 [0.21, 0.68]) than in flocks from unvaccinated breeders. In addition, the mean load of culture-positive samples was lower in broilers from vaccinated breeders by 0.30 log most probable number per sample (95% confidence interval of -0.51, -0.09; P = 0.004), corresponding to a 50% decrease in Salmonella loads. In summary, vaccination of broiler breeder pullets increased humoral immunity in the breeders and reduced Salmonella prevalences and loads in their broiler progeny, but did not significantly decrease Salmonella in the breeder farm environment.

Study Objectives: To determine the prevalence and polysomnographic correlates of insomnia in subjects with self-reported medical disorders. Design: Prospective cross-sectional study. Participants: Community-based sample of 3282 men and women aged 18 to 65 years old, with a subset who underwent polysomnography. Measurements: Self-reported measures of sleep habits and current health, and polysomnographic sleep variables. Results: The prevalence of insomnia was 21.4%. The adjusted odds of insomnia were 2.2 times as high in persons with any medical disorders as in those without medical disorders. Specifically, odds of insomnia were higher in people with heart disease (OR = 1.6 [95% CI: 1.2-23], P = 0.004), hypertension (1.5 [12-18], P insomnia increased with increasing number of medical disorders. However, polysomnographic sleep was not significantly different in persons with or without medical disorders for most disorders assessed. Conclusion: This large population-based study suggests that insomnia is highly prevalent in diverse chronic medical disorders. However, polysomnographic evidence of disturbed sleep is present in only a subset of comorbid insomnia populations. Citation: Budhiraja R; Roth T; Hudgel DW; Budhiraja P; Drake CL.

Drivers outside their country of residence are at a safety disadvantage when compared to native counterparts. This research aimed to (1) investigate if out-of-state drivers in the United States experienced the same vulnerabilities as foreign drivers, and (2) examine the relations of out-of-state crashes to various human and environmental factors. Crash data from Florida, Maine, Minnesota, and Nevada was analyzed to model fault using logistic regressions. Univariate regressions showed that out-of-state drivers had increased odds of fault, ranging from 17% to 92%, for a single-vehicle crash compared to in-state drivers in all states except Florida, where there was no difference between groups. Odds were elevated for out-of-state drivers in two-vehicle crashes by 3% to 19% in all states except Florida and Minnesota, where, again, there was no difference between groups. Human and environmental factors such as age, sex, driving conditions, and seasons were examined with multivariate regressions for in- and out-of-state groups separately, and their odds ratios were compared. For single-vehicle crashes age, sex, road grade, surface condition, light conditions, and day of week were factors that increased at least one of the two groups' odds of fault in all states. Sex, surface condition, and light conditions increased the odds of fault for at least one of the groups in two-vehicle crashes in all four states. Factors that consistently increased odds of fault for both single- and two-vehicle crashes were males, non-vehicle owners, curves, and inclement weather. Although there were several factors in each state that increased odds of fault for out-of-state drivers, no factors consistently increased odds of fault for out-of-state drivers across all four states.

High-spin states of the odd-odd nucleus 74 Br were investigated via the reactions 58 Ni ( 19 F,2pn) 74 Br and 65 Cu( 12 C,3n) 74 Br at beam energies of 62 and 50 MeV, respectively. On the basis of coincidence data new levels have been introduced and partly grouped into rotational bands. Some of these new states decay to known levels of negative-parity bands built on both the ground state and the long-lived 4 (+) isomer. Thus, an excitation energy of 13.8 keV has been deduced for the long-lived isomer in 74 Br. The level sequences observed are interpreted in terms of Nilsson configurations in conjunction with collective excitations

2016-03-01

The revision of the Diagnostic and Statistical Manual of Mental Disorders, 5th ed. (DSM-5) added a new diagnosis of disruptive mood dysregulation disorder (DMDD) to depressive disorders. This study examines the prevalence, comorbidity, and correlates of the new disorder, with a particular focus on its overlap with oppositional defiant disorder (ODD), with which DMDD shares core symptoms. Data were obtained from 597 youth 6-18 years of age who participated in a systematic assessment of symptoms offered to all intakes at a community mental health center (sample accrued from July 2003 to March 2008). Assessment included diagnostic, symptomatic, and functional measures. DMDD was diagnosed using a post-hoc definition from item-level ratings on the Schedule for Affective Disorders and Schizophrenia for School-Age Children that closely matches the DSM-5 definition. Caregivers rated youth on the Child Behavior Checklist. Approximately 31% of youth met the operational definition of DMDD, and 40% had Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV) diagnoses of ODD. Youth with DMDD almost always had ODD (odds ratio [OR] = 53.84) and displayed higher rates of comorbidity with attention-deficit/hyperactivity disorder (ADHD) and conduct disorder than youth without DMDD. Caregivers of youth with DMDD reported more symptoms of aggressive behavior, rule-breaking, social problems, anxiety/depression, attention problems, and thought problems than all other youth without DMDD. Compared with youth with ODD, youth with DMDD were not significantly different in terms of categorical or dimensional approaches to comorbidity and impairment. The new diagnosis of DMDD might be common in community mental health clinics. Youth with DMDD displayed more severe symptoms and poorer functioning than youth without DMDD. However, DMDD almost entirely overlaps with ODD and youth with DMDD were not significantly different than youth with ODD. These findings raise concerns

This study was designed to assess the efficiency of the serum thyrotropin to thyroglobulin ratio for thyroid nodule evaluation in euthyroid patients. Cross-sectional study. Sun Yat-sen University Cancer Center, State Key Laboratory of Oncology in South China. Retrospective analysis was performed for 400 previously untreated cases presenting with thyroid nodules. Thyroid function was tested with commercially available radioimmunoassays. The receiver operating characteristic curves were constructed to determine cutoff values. The efficacy of the thyrotropin:thyroglobulin ratio and thyroid-stimulating hormone for thyroid nodule evaluation was evaluated in terms of sensitivity, specificity, positive predictive value, positive likelihood ratio, negative likelihood ratio, and odds ratio. In receiver operating characteristic curve analysis, the area under the curve was 0.746 for the thyrotropin:thyroglobulin ratio and 0.659 for thyroid-stimulating hormone. With a cutoff point value of 24.97 IU/g for the thyrotropin:thyroglobulin ratio, the sensitivity, specificity, positive predictive value, positive likelihood ratio, and negative likelihood ratio were 78.9%, 60.8%, 75.5%, 2.01, and 0.35, respectively. The odds ratio for the thyrotropin:thyroglobulin ratio indicating malignancy was 5.80. With a cutoff point value of 1.525 µIU/mL for thyroid-stimulating hormone, the sensitivity, specificity, positive predictive value, positive likelihood ratio, and negative likelihood ratio were 74.0%, 53.2%, 70.8%, 1.58, and 0.49, respectively. The odds ratio indicating malignancy for thyroid-stimulating hormone was 3.23. Increasing preoperative serum thyrotropin:thyroglobulin ratio is a risk factor for thyroid carcinoma, and the correlation of the thyrotropin:thyroglobulin ratio to malignancy is higher than that for serum thyroid-stimulating hormone. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

Prediabetes has received public attention owing to the increasing prevalence worldwide. Mounting evidence has indicated that inflammation directly contributed to the etiology of glucose metabolism disorders. Although immunoglobulins play a crucial role in immune responses, little research has been done on the link between immunoglobulins and prediabetes in adults. Hence, the aim of the present study was to explore the associations between immunoglobulins levels and prevalence of prediabetes in a general adult population. A cross-sectional study was conducted among 8856 adults (mean±standard deviation age: 48.4±10.7years) in Tianjin, China. The serum immunoglobulins concentrations were measured by the immunonephelometric technique. Prediabetes was diagnosed using the following parameters in accordance with the American Diabetes Association: fasting plasma glucose, postprandial glucose and glycosylated hemoglobin. The associations between concentrations of immunoglobulins and the prevalence of prediabetes were assessed using multiple logistic regression models. Overall, the prevalence of prediabetes was 37.4% (3311/8856). After controlling for confounders, compared with the lowest quintile, the odds ratios (95% confidence interval) of prediabetes for the highest quintile of immunoglobulins (immunoglobulin G, immunoglobulin E, immunoglobulin M and immunoglobulin A) were as follows: 1.06 (0.91-1.23), 1.31 (1.13-1.52), 0.86 (0.74-1.01), and 1.19 (1.03-1.38) (P for trend were 0.35, prediabetes prevalence. There was also a trending association between immunoglobulin M concentrations and prediabetes prevalence. Further studies are necessary to clarify if there is a causal association of immunoglobulins in prediabetes or if they reflect early immunologic disturbances in these patients.

Undergraduate medical students have been the most distressed group among the student population. Depression and anxiety have been found to be more prevalent in this group of students compared to others. This study was conducted to determine the prevalence and predictors of suicidality among undergraduate medical students in a public university. This was an analytical cross-sectional study, conducted in a public university in Selangor, Malaysia. Data were collected using self-administered questionnaires from January to February 2013, and analysed using the Statistical Package for Social Sciences Software (version 21). Out of 625 undergraduate medical students, 537 (85.9%) participated in the study. The prevalence of the suicidality among undergraduate medical students was 7.0%. The significant predictors of suicidality based on multiple logistic regression were the respondent's lifetime suicide attempts (Adjusted Odds Ratio, AOR 10.4, 95% CI 2.7 to 40.9); depression (AOR 5.9, 95% CI 1.5 to 23.0); breaking off a steady love relationship (AOR 5.4, 95% CI 1.3 to 22.4); hopelessness (AOR 4.9, 95% CI 1.1 to 21.6); and something valued being lost or stolen (AOR 4.4, 95% CI 1.2 to 15.9). These findings indicate that mental health care services should be strengthened at university level. The results show a need for an intervention programme to reduce suicidality among the undergraduate medical students.

Purpose: To investigate whether the prevalence of eating disorders (EDs) differs across diverse gender identity groups in a transgender sample. Methods: Secondary analysis of data from Project VOICE, a cross-sectional study of stress and health among 452 transgender adults (ages 18-75 years) residing in Massachusetts. Age-adjusted logistic regression models were fit to compare the prevalence of self-reported lifetime EDs in female-to-male (FTM), male-to-female (MTF), and gender-nonconforming participants assigned male at birth (MBGNC) to gender-nonconforming participants assigned female at birth (FBGNC; referent). Results: The age-adjusted odds of self-reported ED in MTF participants were 0.14 times the odds of self-reported ED in FBGNC participants ( p =0.022). In FTM participants, the age-adjusted odds of self-reported ED were 0.46 times the odds of self-reported ED in FBGNC participants, a marginally significant finding ( p =0.068). No statistically significant differences in ED prevalence were found for MBGNC individuals. Conclusions: Gender nonconforming individuals assigned a female sex at birth appear to have heightened lifetime risk of EDs relative to MTF participants. Further research into specific biologic and psychosocial ED risk factors and gender-responsive intervention strategies are urgently needed. Training clinical providers and ensuring competency of treatment services beyond the gender binary will be vital to addressing this disparity.

We investigated the association between the triglycerides to high-density lipoprotein cholesterol (TG/HDL) ratio and sarcopenia in elderly Korean males. We examined the relationship between the TG/HDL ratio and sarcopenia in 879 elderly males ≥60years who participated in the 2010-2011 KNHANES. Sarcopenia was defined as an appendicular skeletal muscle mass (ASM) divided by the weight (%), which is >1 SD below the mean for young adults. The odds ratios (ORs) for sarcopenia were calculated using multiple logistic regression across the TG/HDL ratio quartiles (Q1: ≤1.4, Q2: 1.5-2.4, Q3: 2.5-3.8 and Q4: ≥3.9) after adjusting for confounding variables. The prevalence of sarcopenia significantly increased in accordance with TG/HDL ratio quartiles. Compared with the lowest quartile of the TG/HDL ratio, the corresponding OR (95% CI) of the highest quartile of the TG/HDL ratio for sarcopenia was 2.10 (1.12-3.91) after adjusting for age, body mass index (BMI), cigarette smoking, alcohol intake and physical activity. TG/HDL ratio was positively related with a higher risk of sarcopenia in elderly Korean males. Copyright © 2016 Elsevier B.V. All rights reserved.

The present study aimed to investigate the prevalence and correlates of dental caries in elderly population in northeast China. A community-based, cross-sectional study among 2376 elderly subjects (age: 65-74 years) from nine urban areas and nine rural areas in three provinces of northeast China was conducted using multistage stratified random sampling per the World Health Organization oral health survey methodology. Decayed-missing-filled teeth (DMFT) and decayed-filled teeth (DFT) indices were used to evaluate the prevalence of dental caries. Face-to-face questionnaire survey on oral health was performed in a randomly selected subset (n = 1197). T test and chi square test were employed to compare groups for continuous and categorical variables, respectively. Multivariate logistic regression was used to estimate odds ratios (ORs) and corresponding confidence intervals (CIs). 67.5% of elderly subjects reported dental caries (average DFT = 2.68±3.40), and the prevalence was higher in urban areas (Ppopulation in urban areas (OR 1.713; 95% CI 1.337-2.195), smoking (OR 1.779; 95% CI 1.384-2.288), and individuals without dental insurance (OR 2.050; 95% CI 1.120-3.754) with dental caries. The prevalence of dental caries in the elderly population in northeast China is high. The elderly from urban areas who smoke and who do not have a dental insurance are at a higher risk to develop dental caries.

Full Text Available This study was conducted to estimate the prevalence and associated factors of subjective halitosis in adolescents. In total, 359,263 participants were selected from the Korea Youth Risk Behavior Web-based Survey (KYRBWS from 2009 through 2013. Demographic data including age, sex, obesity and residency; psychosocial factors such as subjective health, stress, and economic levels; and dietary factors such as alcohol consumption; smoking; and fruit, soda, fast food, instant noodle, confection, and vegetable consumption were analyzed for correlations with halitosis using simple and multiple logistic regression analyses with complex sampling. In total, 23.6% of the participants reported the presence of halitosis. The following subjectively assessed factors were related to halitosis: poor health status (adjusted odds ratio [AOR] = 2.56, overweight or obese (AOR = 1.37, stress (AOR = 2.56, and lower economic levels (AOR = 1.85. The high intake of fast food (AOR = 1.15, instant noodles (AOR = 1.17, and confections (AOR = 1.17 and the low intake of fruits (AOR = 1.22 and vegetables (AOR = 1.19 were also related to halitosis. The prevalence of subjective halitosis in the studied adolescents was 23.6%. Specific psychosocial factors and dietary intake were related to halitosis.

Full Text Available OBJECTIVES: The aim of this study was to assess the prevalence of Temporomandibular Disorders (TMD, using the Research Diagnostic Criteria for TMD (RDC/TMD in women with episodic and chronic migraine (M and CM, as well as in asymptomatic women. METHOD: Sample consisted of 61 women, being 38 with M and 23 with CM, identified from a headache outpatient center; we also investigated 30 women without headaches for at least 3 months (women without headache group - WHG. Assessment of TMD was conducted by a physical therapist who was blind to the headache status. RESULTS: The prevalence of TMD, assessed through the RDC, was 33.3% in the WHG, 86.8% in the M group and 91.3% of the CM group. Differences were significant when comparing M and CM groups with WHG (p0.05 as well as higher risk for TMD [odds ratio (OR=3.15, 95% confidence interval (CI 1.73-5.71 and OR=3.97, 95%CI 1.76-8.94]. CONCLUSION: Women with migraine are more likely to have muscular and articular TMD, suggesting that both disorders might be clinically associated, which demonstrate the importance of physical therapy assessment in the multidisciplinary team.

To investigate the prevalence of antenatal depression and to assess whether the common risk factors identified in previous studies were applicable to women in Sabah, Malaysia. A prospective cohort study of 2072 women was conducted in Sabah during 2009-2010. Participants were recruited at 36-38 weeks of gestation to complete a self-administered questionnaire regarding their demographic, socioeconomic and health characteristics. The presence of depression was assessed using the validated Malay version of the Edinburgh Postnatal Depression Scale. The prevalence of antenatal depression was 13.8% [95% confidence interval (CI) 12.3%, 15.3%]. Women who were happy with the pregnancy [odds ratio (OR) 0.43, 95% CI 0.21, 0.89] and those with a planned pregnancy (OR 0.45, 95% CI 0.33, 0.60) were less likely to suffer from antenatal depression. Pregnant mothers who were taking oral contraceptives before pregnancy (OR 1.63, 95% CI 1.20, 2.22) and women who experienced antenatal anxiety (OR 3.17, 95% CI 2.35, 4.26) appeared to have an increased risk of antenatal depression. A substantial proportion of women suffered from antenatal depression in Sabah, Malaysia. Screening and culturally tailored intervention programs targeting vulnerable subgroups of women in the early stage of pregnancy are recommended to deal with the problem.

The estimated number of US workers potentially exposed to asthmagens ranges from 8 to 20 million. This study was undertaken to estimate the US prevalence of asthma in adults by industry of employment and to identify industries with elevated risk of asthma. Prevalence analysis was performed on 20,991 adults, 18 years of age and older who participated in the 2001 National Health Interview survey. We used SUDAAN software to estimate the prevalence of self-reported physician diagnosed asthma by industry, and odds ratios (ORs) for asthma and industry adjusted for age, sex, race, and smoking status. The overall prevalence of physician diagnosed asthma was 6.5% (95% CI 6.1-6.9); 4.7% (95% CI 4.1-5.3) for males and 8.5% (95% CI 7.9-9.1) for females. In whites, the prevalence and ORs were significantly elevated for printing, publishing, and allied industries (OR = 2.4, 95% CI 1.2-5.0) and health care (OR = 1.3, 95% CI 1.0-1.7). In blacks, ORs were elevated for furniture, lumber, and wood (OR = 5.9, 95% CI 1.4-25.4) and entertainment and recreation industries (OR = 4.1, 95% CI 1.1-15.9). Other industries with elevated ORs included automobile dealers and gasoline station; durable goods; elementary, secondary schools, and colleges; other personal services; eating and drinking places; entertainment and recreation services; and utility and sanitary. Industries with elevated prevalence of asthma are identified. This information helps to target workplaces where detailed investigations for prevention and control may be appropriate.

Full Text Available Abstract Background Lifestyle factors, such as an unbalanced diet and lack of physical activity, may affect the prevalence of metabolic syndrome (MetS in schizophrenic patients. The aim of this study was to compare the MetS prevalence between inpatients and outpatients among schizophrenic population in Japan. Methods We recruited inpatients (n = 759 and outpatients (n = 427 with a Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV diagnosis of schizophrenia or schizoaffective disorder from 7 psychiatric hospitals using a cross-sectional design. MetS prevalence was assessed using three different definitions, including the adapted National Cholesterol Education Program Adult Treatment Panel (ATP III-A. Results The overall MetS prevalences based on the ATP III-A definition were 15.8% in inpatients and 48.1% in outpatients. In a logistic regression model with age and body mass index as covariates, being a schizophrenic outpatient, compared to being a schizophrenic inpatient, was a significant independent factor (odds ratio = 3.66 for males, 2.48 for females in the development of MetS under the ATP III-A definition. The difference in MetS prevalence between inpatients and outpatients was observed for all age groups in males and for females over 40 years of age. Conclusions Outpatients with schizophrenia or schizoaffective disorder in Japan had a high prevalence of MetS compared to inpatients. MetS in schizophrenic outpatients should be carefully monitored to minimize the risks. A change of lifestyle might improve MetS in schizophrenic patients.

Insulin and uric acid were shown affect the prevalence of Metabolic Syndrome (MetS), but no studies examine their interaction. Therefore, we conducted this study to determine their biological interaction in subjects from central Mexico. 433 subjects were enrolled for a cross-sectional study. MetS was defined according to the Harmonizing Definition. Hyperuricemia was defined as ≥7.0 mg/dL in males and ≥5.8 mg/dL in females. Hyperinsulinemia was defined as ≥11.0 μU/mL. Pearson correlation coefficient (r) was calculated to determine the association between uric acid or insulin and MetS. Logistic regression was used to determine the risk (odds ratio) of developing MetS. Biological interactions were determined by the PROCESS Macro and Anderson's method. Insulin and uric acid levels were elevated in MetS positive group (p uric acid and insulin was associated with the number of MetS components (PROCESS Model 1, interaction coefficient = -0.009, 95%CI: -0.017 to -0.001, p = .036). Johnson-Neyman analysis suggests the interaction is lost when uric acid concentration increased >7.0 mg/dL. When the cohort was separated by hyperinsulinemia and hyperuricemia, there was a significant risk of developing MetS for subjects with hyperuricemia (odds ratio = 2.3; 95%CI: 1.1-4.8, p uric acid and insulin augments the prevalence of MetS; however, no biological interaction was determined for hyperuricemia and hyperinsulinemia.

Full Text Available Objective: Personality disorder is a multi-factorial condition in which workplace stress plays a significant role. This study was undertaken due to scarcity of information regarding the role of workplace stress which can cause personality disorder among nurses. We aimed to evaluate the prevalence of personality disorders in nurses working in different hospital departments and assess factors affecting its onset. Methods: In this cross-sectional study the personality disorders of nurses working in various hospital departments were evaluated based on Minnesota Multiphasic Personality Inventory-2 (MMPI-2 test. After the completion of questionnaires, data were entered to MMPI-2 test’s special software and the final result was interpreted based on the opinion of a clinical psychologist. Finally, multivariate logistic regression model was used to assess the independent effect of the mentioned factors on prevalence of personality disorders in nurses. Results: We gathered data from 2 groups of participants (n = 206. These groups included nurses in emergency departments and nurses in other hospital units. The mean of age was 32.5 ± 6.9 years. Overall, 54.3% (n = 38 of non-emergency nurses and 45.7% (n = 32 of emergency nurses showed symptoms of personality disorders respectively. Multivariate logistic regression analysis showed that history of a serious accident or trauma increased the odds of detecting personality disorders up to 3.8 times (odds ratio [OR] = 3.84; 95% CI: 1.33-11.06; P = 0.01. In addition, an unpleasant incident in the past year increased it up to 2.2 times (OR = 2.23; 95% CI: 1.18 – 4.22; P = 0.01 in both groups. Conclusion: The present study showed that there was no significant difference between emergency departments and other units of hospitals regarding the prevalence of personality disorders among nurses. Overall, somatization, hysteria, and pollyannaish were the most common personality disorders among the studied population

To describe the prevalence and user profile of electronic cigarettes among Spanish adults and evaluate the potential dual use of these devices with combustible or conventional tobacco in 2014 in Spain. Cross-sectional study of a representative sample of the Spanish adult (16-75 years old) population (n=1,016). A computer-assisted telephone survey was conducted in 2014. The prevalence and 95% confidence intervals (95% CI) for the use of electronic cigarettes stratified by gender, age, tobacco consumption and social status were calculated. The sample was weighted and a logistic regression model adjusted to obtain the crude odds ratios (OR) adjusted by gender, age and social status. 10.3% (95% CI: 8.6-12.4) of the Spanish adult population stated being ever users of electronic cigarettes (2% current users, 3.2% past users and 5.1% experimental users). Among current electronic cigarette users, 57.2% also smoked combustible or conventional tobacco, 28% had never smoked and 14.8% were former smokers. The prevalence of electronic cigarette use was higher in the younger population (adjusted OR=23.8; 95% CI: 2.5-227.7) and smokers of combustible tobacco (adjusted OR=10.1; 95% CI: 5.8-17.5). The use of electronic cigarettes in Spain is scarce and is most prevalent among young people and tobacco smokers. Nevertheless, one out of four current electronic cigarette users have never smoked. Hence, the regulation of these devices should be reinforced to avoid a possible gateway to nicotine products among never smokers. Copyright © 2016 SESPAS. Publicado por Elsevier España, S.L.U.

Full Text Available Abstract Background Thrombocytopenia is associated with the natural history of hepatitis C virus (HCV infection and anti-viral therapy. Recent, national estimates of the clinical burden of thrombocytopenia among HCV-infected individuals in the United States are unavailable. Bi-yearly data from the 1999-2000 to 2007-2008 National Health and Nutrition Examination Surveys (NHANES were used to examine the prevalence of thrombocytopenia among HCV-infected individuals in the United States. Results Among 467 HCV-infected individuals in the survey (weighted population = 3,597,039, mean weighted age was 46.7 years (standard deviation = 15.5 and 61.7% were male. Overall, 7.6% met the study definition of TCP at the 150 × 109/L threshold; 4.5%, 2.0%, and 0.8% had platelet counts below 125, 100, and 75 × 109/L, respectively. The 2-year weighted prevalences of thrombocytopenia (150 × 109/L threshold from 1999-2008 were 4.9%, 8.6%, 6.5%, 4.1%, and 12.9%. The unadjusted biannual time trend (odds ratio was 1.16 (95% confidence interval = 0.82-1.64. In the two adjusted models, the odds by time ranged from 1.24-1.40, depending on whether the model included demographic or laboratory variables or both, but did not reach statistical significance. Age was positively and significantly related to thrombocytopenia status. Conclusions As the HCV-infected population ages, the prevalence of thrombocytopenia is expected to rise. This study provides limited evidence of such an effect at the national level.

Full Text Available Abstract Background Developing countries are undergoing an epidemiological transition, from Communicable or Infectious to 'Non-Communicable' diseases (NCDs, such that cardiovascular disease, chronic respiratory diseases, cancer, and diabetes were responsible for 60% of all deaths globally in 2005, with more than 75% of these deaths occurring in developing countries. A survey was conducted to determine among other objectives the prevalence of diabetes and its association with physical fitness and biological factors. Methods A cross sectional study utilizing a modified World Health Organization's STEPwise approach to surveillance of NCDs was conducted in Lusaka district, Zambia. A multi-stage cluster sampling technique was used to select study participants of age 25 years or older. All eligible members of a household that was selected were invited to participate in the study. Unadjusted odds ratios (OR, and adjusted odds ratios (AOR together with their 95% Confidence Intervals (CI were obtained using Complex samples logistic regression Results A total of 1928 individuals participated in the survey, of which 33.0% were males. About half of the participants were of age 25-34 years (53.2%, and about a third of the respondents had attained secondary level of education (35.8%. The combined prevalence for impaired glucose level or diabetes was 4.0%. Age and mild hypertension were significantly associated with impaired levels of glucose or diabetes. Compared to participants in the age group 25-34 years, older participants were more likely to have impaired glucose level or diabetes (AOR = 2.49 (95%CI [1.35, 2.92] for 35-44 years age group, and AOR = 3.80 (95%CI [2.00, 7.23] for 45 + years age group.

Full Text Available Objective: To study the prevalence and risk factors of intestinal parasitic infections among hill tribe schoolchildren who attended 10 border patrol police schools in 2012, Chiang Rai, Thailand. Methods: A total of 339 subjects were recruited into the study from 2 194 children. Questionnaire was tested for validity and reliability before use. About 5 g stool specimens were collected and investigated for intestinal parasite infections by using cellophane-covered thick smear technique. Logistic regression at α = 0.05 was used to test the associations between variables to find risk factors. Results: There were 339 subjects of whom 51.9% were males and 66.1% were Buddhist; racially 31.2% were Akha and 30.4% were Kmong; mean age was 10.3 years old (minimum = 6, maximum = 16. The prevalence of parasitic infection was 9.7%. After controlling for age, sex, religion, parents’ education levels and parents’ occupations, the only factor that showed a statistically significant association with intestinal parasitic infection was the source of drinking water. The group of drinking mountain piped water had a greater risk of 8.22 times (adjusted odds ratio = 8.22, 95%; confidence interval: 1.07–63.18 compared to the drinking commercially bottled water group, while the group of drinking underground water had a greater risk of 9.83 times (adjusted odds ratio = 9.83, 95%; confidence interval: 0.93–104.12 compared to the drinking commercially bottled water group. Conclusions: Drinking water contaminated by soil was shown to be an important risk factor for intestinal parasitic infection in hill tribe schoolchildren living in mountainous border areas in the northern part of Thailand. Safer alternative drinking water source should be provided along with health education for schools and villagers to be aware of the risk of intestinal parasites from drinking water sources such as mountain piped or underground wells. Such sources are likely to contain higher soil

This study estimated the prevalence of anaemia and associated factors in a probability sample of 993 chil- dren aged 6-59 months in Cape Verde, West Africa. Odds ratio (OR) and 95% confidence interval (95% CI) were estimated from a hierarchical model for multiple analysis to assess the association between anaemia and explanatory variables. The prevalence of anaemia was 51.8% (95% CI 47.7-55.8). Children who resided within poor household conditions (OR 1.99; 95% CI 1.06-3.71) were below 24 months of age (OR 3.23; 95% CI 2.03-5.15) and recently experienced diarrhoea (OR 1.58; 95% CI 0.99-2.50) were at high risk of anaemia. Anaemia should be considered a serious public-health concern in Cape Verde, mainly for chil- dren below 24 months. Further, special consideration should be given to children who have experienced recent diarrhoea and belong to families residing in poor household conditions.

2014-01-01

Overweight and obesity are major pediatric public health problems in the United States; however, limited data exist on the prevalence and correlates of overnutrition in children with autism. Through a large integrated health care system's patient database, we identified 6672 children ages 2 to 20 years with an assigned ICD-9 code of autism (299.0), Asperger syndrome (299.8), and control subjects from 2008 to 2011 who had at least 1 weight and height recorded in the same visit. We calculated age-adjusted, sex-adjusted body mass index and classified children as overweight (body mass index 85th to 95th percentile) or obese (≥ 95th percentile). We used multinomial logistic regression to compare the odds of overweight and obesity between groups. We then used logistic regression to evaluate factors associated with overweight and obesity in children with autism, including demographic and clinical characteristics. Compared to control subjects, children with autism and Asperger syndrome had significantly higher odds of overweight (odds ratio, 95% confidence interval: autism 2.24, 1.74-2.88; Asperger syndrome 1.49, 1.12-1.97) and obesity (autism 4.83, 3.85-6.06; Asperger syndrome 5.69, 4.50-7.21). Among children with autism, we found a higher odds of obesity in older children (aged 12-15 years 1.87, 1.33-2.63; aged 16-20 years 1.94, 1.39-2.71) compared to children aged 6 to 11 years. We also found higher odds of overweight and obesity in those with public insurance (overweight 1.54, 1.25-1.89; obese 1.16, 1.02-1.40) and with co-occurring sleep disorder (obese 1.23, 1.00-1.53). Children with autism and Asperger syndrome had significantly higher odds of overweight and obesity than control subjects. Older age, public insurance, and co-occurring sleep disorder were associated with overweight or obesity in this population. Copyright © 2014 Academic Pediatric Association. Published by Elsevier Inc.

Background: Human papilloma virus causes benign and malignant abnormalities in different part of the body. The link between high risk types of HPV and some anogenital and aerodigestive tract cancer is well established. Oral HPV infection plays a role in developing oropharyngeal squamous cell carcinoma. We studied the prevalence of oral HPV in healthy individuals and its relative risk factors. Methods: Saliva samples of 114 healthy subjects were collected for HPV DNA analysis. Volunteers completed questionnaires and signed a written consent. For data analysis descriptive statistic, chi square test and odds ratio was used. Results: The frequency of oral HPV in healthy individuals was 6.1 %(seven participant).The most frequent type was HPV-18 in five of them. HPV-6 and HPV-66 each was detected in one case. Relation of oral HPV positivity to demographic features and risk factors was not statistically significant. Conclusions: The prevalence of oral HPV infection in our community is the same as many other communities of developing countries, stressing that HPV-18 were the dominant type. PMID:23514804

After stratification by gender, the significance still existed in the 3rd and 4th quartile in males and the 4th quartile in females. For abdominal obesity, the multivariable-adjusted OR (95% CI of the 3rd and 4th quartile of dietary BCAA ratio were 0.351 (0.145–0.845 and 0.376 (0.161–0.876, respectively (all p < 0.05. This significance was stronger in males. Further studies indicated that dietary BCAA ratio was inversely associated with 2-h postprandial glucose (2 h-PG and status of inflammation. In conclusion, a higher ratio of dietary BCAA is inversely associated with prevalence of obesity, postprandial glucose and status of inflammation in young northern Chinese adults.

Objectives: The aim of this study was to investigate the prevalence of xerostomia among dental patients and explore the possible risk factors and symptoms associated with this condition. Patient and Methods: The prevalence of xerostomia and its associations were investigated among patients (n=1132) who were visiting the department of oral medicine at shorish dental speciality in sulaimani city. The age range was between 10-79 years. 512 (45.2%) of participants were males and 620 (54.8%) were females. The data collected were age, sex, systemic diseases, medications and habit of smoking. Logistic regression models to estimate odds ratios and 95% confidence intervals were used to investigate the association of xerostomia with age, systemic diseases and medications and Chi Square test was also used to analyze the data. Results: Prevalence of xerostomia was 16.07%. Prevalence of xerostomia was significantly higher among females (19.51%) than males (11.91%) (P=0.001). The most common diseases with the highest prevalence of xerostomia were psychological disorders (57.14%) followed by diabetes mellitus (53.84%), neurological disorders (40%), thyroid disorders (37.5%) and hypertension (36.48%). The most common medication with the highest prevalence of xerostomia was antihistamine (66.66%) followed by psychotherapeutic medications (60%), pain medications (55.88%), endocrinologic agents (51.21%), antidyslipidic agents (50%) and antihypertensive medication (38.98%). Xerostomia was significantly associated with ageing (OR: 1.02, P=0.000), systemic diseases (OR: 2.80, P=0.000) and medications (OR: 5.17, P=0.000). There was a high prevalence of reported symptoms of xerostomia and these symptoms were more prevalent among females, Prevalence of xerostomia was higher in heavy smoker patients (19.48%) than non smoker patients but not significantly (16.14%) (p= 0.44). Conclusions: There was a high prevalence of xerostomia among dental patients; xerostomia was significantly more

Full Text Available Objectives: To determine the dental arch dimensions and arch forms in a sample of Saudi orthodontic patients, to investigate the prevalence of Bolton anterior and overall tooth size discrepancies, and to compare the effect of gender on the measured parameters. Methods: This study is a biometric analysis of dental casts of 149 young adults recruited from different orthodontic centers in Jeddah, Saudi Arabia. The dental arch dimensions were measured. The measured parameters were arch length, arch width, Bolton’s ratio, and arch form. The data were analyzed using IBM SPSS software version 22.0 (IBM Corporation, New York, USA; this cross-sectional study was conducted between April 2015 and May 2016. Results: Dental arch measurements, including inter-canine and inter-molar distance, were found to be significantly greater in males than females (p less than 0.05. The most prevalent dental arch forms were narrow tapered (50.3% and narrow ovoid (34.2%, respectively. The prevalence of tooth size discrepancy in all cases was 43.6% for anterior ratio and 24.8% for overall ratio. The mean Bolton’s anterior ratio in all malocclusion classes was 79.81%, whereas the mean Bolton’s overall ratio was 92.21%. There was no significant difference between males and females regarding Bolton’s ratio. Conclusion: The most prevalent arch form was narrow tapered, followed by narrow ovoid. Males generally had larger dental arch measurements than females, and the prevalence of tooth size discrepancy was more in Bolton’s anterior teeth ratio than in overall ratio.

CP-odd Phase Correlations and Electric Dipole Moments

2005-01-01

We revisit the constraints imposed by electric dipole moments (EDMs) of nucleons and heavy atoms on new CP-violating sources within supersymmetric theories. We point out that certain two-loop renormalization group corrections induce significant mixing between the basis-invariant CP-odd phases. In the framework of the constrained minimal supersymmetric standard model (CMSSM), the CP-odd invariant related to the soft trilinear A-phase at the GUT scale, theta_A, induces non-trivial and distinct CP-odd phases for the three gaugino masses at the weak scale. The latter give one-loop contributions to EDMs enhanced by tan beta, and can provide the dominant contribution to the electron EDM induced by theta_A. We perform a detailed analysis of the EDM constraints within the CMSSM, exhibiting the reach, in terms of sparticle spectra, which may be obtained assuming generic phases, as well as the limits on the CP-odd phases for some specific parameter points where detailed phenomenological studies are available. We also i...

Small studies have suggested that Marfan syndrome is associated with a number of cerebrovascular complications. We sought to determine whether a clinical diagnosis of Marfan syndrome is associated with a higher prevalence of cerebrovascular diseases than the general population by performing a case-control study of hospitalized patients in the Nationwide Inpatient Sample (NIS). Using the 2000-2012 NIS, we performed a case-control study matching cases of Marfan syndrome to controls without such a diagnosis. The prevalence of various cerebrovascular diseases between the 2 groups were compared, and multivariate logistic regression was used to adjust for suspected comorbidities. Between 2000 and 2012, there were a total of 13,883 discharges carrying a diagnosis of Marfan syndrome. On univariate analysis, patients with Marfan syndrome were more likely to have a primary or secondary diagnosis of hemorrhagic stroke (0.5% versus 0.3%, odds ratio [OR] = 1.56, 95% confidence interval [CI] = 1.06-2.29, P = 0.02) as well as intracranial hemorrhage (subarachnoid hemorrhage [SAH] and hemorrhagic stroke) (0.3% versus 0.2%, OR = 1.72, 95% CI = 1.05-2.82, P = 0.03). Patients hospitalized with Marfan syndrome were significantly more likely to have carotid dissection (0.3% versus 0.0%, OR = 11.69, 95% CI = 3.60-38.08, P Marfan syndrome had significantly higher odds of ischemic stroke (OR = 1.20, 95% CI = 1.02-1.43, P = 0.03), hemorrhagic stroke (OR = 1.75, 95% CI = 1.18-2.63, P = 0.005), carotid artery dissection (OR = 11.94, 95% CI = 4.23-50.03, P Marfan syndrome when compared with controls.

The prevalence of childhood overweight and obesity has become a public health problem worldwide. The objectives of the study were: 1) to establish the BMI prevalence in 12-year olds residing in Puerto Rico, and 2) to determine BMI differences by sex, public-private school type, and geographic regions. Data was obtained from an island-wide probabilistic stratified sample of 1,582 twelve-year-olds (53% girls and 47% boys). The BMI was determined using the National Health and Nutrition Examination Survey procedures. Children were categorized as underweight, healthy weight, overweight or obese using the Center for Disease Control and Prevention's age and gender specific growth charts. A logistic regression model was used to estimate BMI category prevalence. Odds ratios were calculated using a multinomial regression. In this study, 18.8% of the children were overweight and 24.3% were obese. A higher prevalence of obesity was observed in boys as compared to girls, 28.2% vs. 20.2%, respectively. The estimated prevalence of overweight and obesity in children from public schools was lower than for those from private schools. After adjusting for type of school and region, boys had a significantly higher risk of being obese (64%) as compared to girls. In public schools, boys had a lower prevalence of being overweight while girls had a higher prevalence compared to children attending private schools. Girls attending private schools had a higher obesity prevalence (27.8%) compared to girls from public schools (19.8%). The prevalence of underweight (2.7%) is slightly lower than in the United States. The prevalence of overweight and obesity of 12-year-olds residing in PR was 18.8% and 24.3%, respectively; higher than in the U.S. (by groups). Boys were at higher risk of obesity than girls. There is an urgent need to implement public health policies/programs to reduce the prevalence of overweight and obesity in children in PR.

Full Text Available The prevalence of physical violence during pregnancy varies widely in different societies. To assess the incidence of self-reported physical, emotional and sexual violence in pregnancy and describe the association with maternal complication and birth outcomes, 3275 women who gave birth to live-born infants from October 2002 to November 2003 were assessed for self-reported violence in postpartum units of Obstetrics Department of Babol university of Medical Sciences. Outcome data included maternal antenatal hospitalizations, labor and delivery complications and low birth weights and preterm births. Odds ratios and 95% confidence intervals were calculated to measure the association between violence, maternal morbidity and birth outcomes. The prevalence of physical, sexual and emotional domestic violence was respectively 9.1%, 30.8% and 19.2%. Compared with those not reporting physical, sexual and emotional violence, women who did were more likely to deliver by cesarean and to have abnormal progress of labor, premature rupture of membranes, low birth weight, preterm birth and any hospitalization before delivery. Prevalence of physical, emotional or sexual violence during pregnancy was high and was associated with adverse fetal and maternal conditions. These findings support routine screening for physical, emotional and sexual violence in pregnancy and postpartum period to prevent consequences of domestic violence.

The neutrophil-to-lymphocyte ratio (NLR) has been used as a surrogate marker of systemic inflammation. We sought to investigate the association between NLR and wound healing in diabetic wounds. The outcomes of 120 diabetic foot ulcers in 101 patients referred from August 2011 to December 2014 were examined retrospectively. Demographic, patient-specific, and wound-specific variables as well as NLR at baseline visit were assessed. Outcomes were classified as ulcer healing, minor amputation, major amputation, and chronic ulcer. The subjects' mean age was 59.4 ± 13.0 years, and 67 (66%) were male. Final outcome was complete healing in 24 ulcers (20%), minor amputation in 58 (48%) and major amputation in 16 (13%), and 22 chronic ulcers (18%) at the last follow-up (median follow-up time, 6.8 months). In multivariate analysis, higher NLR (odds ratio, 13.61; P = .01) was associated with higher odds of nonhealing. NLR can predict odds of complete healing in diabetic foot ulcers independent of wound infection and other factors. Copyright © 2016 Society for Vascular Surgery. All rights reserved.

The prevalence of cardiovascular disease has been increasing worldwide. As a common pathogenic risk factor, dyslipidemia played a great role in the incidence and progress of these diseases. We investigated to achieve accurate and up-to-date information on the prevalence of dyslipidemia and its associations with other lipid-related diseases in rural North China. Using a complex, multistage, probability sampling design, we conducted a large-scale cross-sectional study of 8528 rural participants aged over 18 years in Shandong Province. Prevalence and characteristics of dyslipidemia were demonstrated. The odds ratios between dyslipidemia types and lipid-related diseases were further analyzed by logistic regression. Among the overall population, 45.8 % suffered from dyslipidemia. The prevalence of lipid abnormality (including high and very high levels) was 18.6, 12.7, 9.8 and 12.7 % for total cholesterol (TC), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) cholesterol and triglycerides (TG), respectively. Among all participants with dyslipidemia, 23.9 % were aware, only 11.5 % were treated, 10.0 % were controlled. For subjects with dyslipidemia, the risk for non-alcoholic fatty liver disease (NAFLD) was highest with a 3.3-fold over that of non-dyslipidmia (OR = 3.30, P Dyslipidemia has become a serious public health issue in rural North China. The rapid increase of high TC and incremental risk of high TG may contribute to the epidemic of AS, NAFLD and DM. It is imperative to develop individualized prevention and treatment guidelines according to dyslipidemia phenotypes.

Mattos, A Z; Mattos, A A

Many different non-invasive methods have been studied with the purpose of staging liver fibrosis. The objective of this study was verifying if transient elastography is superior to aspartate aminotransferase to platelet ratio index for staging fibrosis in patients with chronic hepatitis C. A systematic review with meta-analysis of studies which evaluated both non-invasive tests and used biopsy as the reference standard was performed. A random-effects model was used, anticipating heterogeneity among studies. Diagnostic odds ratio was the main effect measure, and summary receiver operating characteristic curves were created. A sensitivity analysis was planned, in which the meta-analysis would be repeated excluding each study at a time. Eight studies were included in the meta-analysis. Regarding the prediction of significant fibrosis, transient elastography and aspartate aminotransferase to platelet ratio index had diagnostic odds ratios of 11.70 (95% confidence interval = 7.13-19.21) and 8.56 (95% confidence interval = 4.90-14.94) respectively. Concerning the prediction of cirrhosis, transient elastography and aspartate aminotransferase to platelet ratio index had diagnostic odds ratios of 66.49 (95% confidence interval = 23.71-186.48) and 7.47 (95% confidence interval = 4.88-11.43) respectively. In conclusion, there was no evidence of significant superiority of transient elastography over aspartate aminotransferase to platelet ratio index regarding the prediction of significant fibrosis, but the former proved to be better than the latter concerning prediction of cirrhosis.

To determine the prevalence of amblyopia and its determinants in a population-based study in Mashhad County, Iran. This cross-sectional, population-based study was conducted on the population of Mashhad County aged >1 year using randomized stratified cluster sampling. Examinations were performed after selection of the participants and their free transportation to the sampling site. The examinations included the measurement of uncorrected and corrected visual acuity, cycloplegic and non-cycloplegic refraction, cover testing, slit-lamp biomicroscopy, and ophthalmoscopy. In this study, amblyopia was defined as best corrected visual acuity (BCVA) of 20/30 or less or 2-line interocular optotype acuity differences with no pathology. After considering the exclusion criteria, the data of 2739 individuals, 65.6% of whom were women, were analyzed. The mean age of the participants was 29.5±17.5 years. The prevalence of amblyopia was 4.6% (95% CI: 3.77%-5.43%) in the total population. The lowest prevalence was 2.24% in the age group 5-15 years (95% CI: 0.99%-3.48%) and the highest prevalence was 7.14% in the age group 55-65 years (95% CI: 2.64%-11.56%). Anisometropic amblyopia was observed in 45.24% of the amblyopic participants. Isometropic, mixed (strabismic/anisometropic), and strabismic amblyopia were other common causes of amblyopia, with a prevalence of 24.6%, 16.67%, and 13.49% in amblyopic patients, respectively. The odds ratio (OR) of having amblyopia for each 1-year increase in age was 1.02 (95% CI: 1.01-1.03). Amblyopia was less common in people with better socioeconomic status. This study showed the prevalence of amblyopia in all age groups in a population-based study for the first time. The findings of this study regarding the relatively high prevalence of amblyopia in the older population and its lower prevalence in young people indicate attention to amblyopia in recent years.

Epidemiological studies have shown an association between increased bone mineral density (BMD) and osteoarthritis (OA), but whether this represents cause or effect remains unclear. In this study, we used a novel approach to investigate this question, determining whether individuals with High Bone Mass (HBM) have a higher prevalence of radiographic hip OA compared with controls. HBM cases came from the UK-based HBM study: HBM was defined by BMD Z-score. Unaffected relatives of index cases were recruited as family controls. Age-stratified random sampling was used to select further population controls from the Chingford and Hertfordshire cohort studies. Pelvic radiographs were pooled and assessed by a single observer blinded to case-control status. Analyses used logistic regression, adjusted for age, gender and body mass index (BMI). 530 HBM hips in 272 cases (mean age 62.9 years, 74% female) and 1702 control hips in 863 controls (mean age 64.8 years, 84% female) were analysed. The prevalence of radiographic OA, defined as Croft score ≥3, was higher in cases compared with controls (20.0% vs 13.6%), with adjusted odds ratio (OR) [95% CI] 1.52 [1.09, 2.11], P = 0.013. Osteophytes (OR 2.12 [1.61, 2.79], P subchondral sclerosis (OR 2.78 [1.49, 5.18], P = 0.001) were more prevalent in cases. However, no difference in the prevalence of joint space narrowing (JSN) was seen (OR 0.97 [0.72, 1.33], P = 0.869). An increased prevalence of radiographic hip OA and osteophytosis was observed in HBM cases compared with controls, in keeping with a positive association between HBM and OA and suggesting that OA in HBM has a hypertrophic phenotype.

Objective We investigated the prevalence of congenital renal and urologic anomalies in children with congenital hypothyroidism to determine whether further renal and urologic investigations would be of benefit. Study design Prevalence of congenital hypothyroidism was obtained from the New York State Congenital Malformation Registry. The occurrence of urinary tract anomalies were calculated for children with congenital hypothyroidism and compared to children without congenital hypothyroidism. In addition we obtained congenital hypothyroidism data from New York State newborn screening, and the cases were matched to Congenital Malformation Registry. Results Analysis of Congenital Malformation Registry data showed 980 children with congenital hypothyroidism and 3 661 585 children without congenital hypothyroidism born in New York State (1992-2005). Children with congenital hypothyroidism have a significantly increased risk of congenital renal and urological anomalies with the odds ratio (OR) of 13.2 (10.6-16.5). The other significantly increased defects in congenital hypothyroidism were cardiac, gastrointestinal, and skeletal. Analysis of matched data confirmed an increase of congenital renal and urologic anomalies with OR of 4.8 (3.7-6.3). Conclusions Children with congenital hypothyroidism have an increased prevalence of congenital renal and urologic anomalies. We suggest that these children should be evaluated for the presence of congenital renal and urologic anomalies with renal ultrasonography, and that further studies of common genes involved in thyroid and kidney development are warranted.

Penicillin allergy remains the most common drug allergy, with a reported prevalence of 10% in the United States. Epidemiology of penicillin allergy in outpatient populations is relatively scarce. This study sought to determine the prevalence and characteristics of reported penicillin allergy in an urban outpatient population and to identify trends in clinical evaluation and management from a tertiary center serving a large inner-city population. A retrospective review of electronic medical records was performed of adult patients seen in the Internal Medicine Associates Clinic of Mount Sinai Hospital between January 31, 2012, and July 31, 2012. Medical records were selected based on the documentation of penicillin in patient's allergy section. Of the 11,761 patients seen in the clinic, 1348 patients (11.5%) reported a history of penicillin allergy. The most common allergic reactions were rash (37%), unknown/undocumented (20.2%), hives (18.9%), swelling/angioedema (11.8%), and anaphylaxis (6.8%). There was an increased prevalence of penicillin allergy in female patients compared with male patients (odds ratio [OR] = 1.82; 95% CI = 1.60, 2.08; p penicillin allergy compared with Caucasians (OR = 0.51; 95% CI = 0.32, 0.83; p = 0.007). However, only 78 (6%) of the patients reporting penicillin allergy had a referral to an allergy specialist. Overall, improved referral to an allergist will help to identify patients who have penicillin allergy requiring avoidance.

To assess the prevalence and causes of visual impairment in children of South Sinai, and to evaluate outcomes of rehabilitation programs. Population-based, cross-sectional analysis of 2070 healthy school children screened for visual impairment from 2009 through 2010 in cities of South Sinai and their surrounding Bedouin settlements. Visual acuity (VA) was tested using Snellen charts followed by cycloplegic autorefractometry for cases with presenting VA ≤ 6/9. Appropriate eyeglasses were prescribed and VA re-evaluated. This study included 1047 boys and 1023 girls, mean age 10.7 ± 3.1 years. Visual impairment (uncorrected VA ≤ 6/9) was detected in 29.4% of children, while 2.0% had moderate-severe visual impairment (uncorrected VA ≤ 6/24). There were statistically significant differences in prevalence of visual impairment between the studied cities (p visual impairment was significantly higher among girls (p children showed significantly lower prevalences of visual impairment. Only age was a reliable predictor of visual impairment (odds ratio 0.94, p children who received spectacles (p children had some form of visual impairment, 90.32% of which comprised refractive errors (mainly astigmatism) which were significantly corrected with eyeglasses. VA screening and correction of refractive errors are of the utmost importance for ensuring better visual outcomes and improved school performance.

To derive the first systematically calculated estimate of the relative proportion of boys and girls with autism spectrum disorder (ASD) through a meta-analysis of prevalence studies conducted since the introduction of the DSM-IV and the International Classification of Diseases, Tenth Revision. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. The Medline, Embase, and PsycINFO databases were searched, and study quality was rated using a risk-of-bias tool. Random-effects meta-analysis was used. The pooled outcome measurement was the male-to-female odds ratio (MFOR), namely the odds of being male in the group with ASD compared with the non-ASD group. In effect, this is the ASD male-to-female ratio, controlling for the male-to-female ratio among participants without ASD. Fifty-four studies were analyzed, with 13,784,284 participants, of whom 53,712 had ASD (43,972 boys and 9,740 girls). The overall pooled MFOR was 4.20 (95% CI 3.84-4.60), but there was very substantial between-study variability (I 2  = 90.9%). High-quality studies had a lower MFOR (3.32; 95% CI 2.88-3.84). Studies that screened the general population to identify participants regardless of whether they already had an ASD diagnosis showed a lower MFOR (3.25; 95% CI 2.93-3.62) than studies that only ascertained participants with a pre-existing ASD diagnosis (MFOR 4.56; 95% CI 4.10-5.07). Of children meeting criteria for ASD, the true male-to-female ratio is not 4:1, as is often assumed; rather, it is closer to 3:1. There appears to be a diagnostic gender bias, meaning that girls who meet criteria for ASD are at disproportionate risk of not receiving a clinical diagnosis.

Full Text Available Parity is a fundamental quantum number used to classify a state of matter. Materials rarely possess ground states with odd parity. We show that the superconducting state in iron-based superconductors is classified as an odd-parity s-wave spin-singlet pairing state in a single trilayer FeAs/Se, the building block of the materials. In a low-energy effective model constructed on the Fe square bipartite lattice, the superconducting order parameter in this state is a combination of an s-wave normal pairing between two sublattices and an s-wave η pairing within the sublattices. The state has a fingerprint with a real-space sign inversion between the top and bottom As/Se layers. The results suggest that iron-based superconductors are a new quantum state of matter, and the measurement of the odd parity can help to establish high-temperature superconducting mechanisms.

The prevalence of metabolic syndrome (MetS) has increased globally and is associated with an increased risk of cardiovascular diseases that may be related to its association with inflammation. We have assessed whether the prevalence of the MetS correlates with a serum high-sensitivity C-reactive protein (hsCRP) concentration in a population-based sample of US men and women. Participants were selected from the US National Health and Nutrition Examination Survey from 2005 to 2010. Of the 17 689 participants analyzed, 8607 (48.3%) were men. The mean age was 45.8 years in the overall sample (between men and women P = .047). The prevalence of MetS, diabetes mellitus, and hypertension increased across quartiles for hsCRP (all P < .001). Moreover, we found that for the age-, race-, sex-, and smoking-adjusted logistic regression, with increasing hsCRP, the risk of having MetS increased with an odds ratio of 5.20 (95% confidence interval, 4.54-5.93, P < .001) when comparing the highest quartile of serum hsCRP with the lowest. This study provides further evidence for an association between MetS and subclinical inflammation.

To assess, in the general diabetic population, 1) the prevalence of painful neuropathic symptoms; 2) the relationship between symptoms and clinical severity of neuropathy; and 3) the role of diabetes type, sex, and ethnicity in painful neuropathy. Observational study of a large cohort of diabetic patients receiving community-based health care in northwest England (n = 15,692). Painful diabetic neuropathy (PDN) was assessed using neuropathy symptom score (NSS) and neuropathy disability score (NDS). Prevalence of painful symptoms (NSS ≥5) and PDN (NSS ≥5 and NDS ≥3) was 34 and 21%, respectively. Painful symptoms occurred in 26% of patients without neuropathy (NDS ≤2) and 60% of patients with severe neuropathy (NDS >8). Adjusted risk of painful neuropathic symptoms in type 2 diabetes was double that of type 1 diabetes (odds ratio [OR] = 2.1 [95% CI 1.7-2.4], P diabetic patients have painful neuropathy symptoms, regardless of their neuropathic deficit. PDN was more prevalent in patients with type 2 diabetes, women, and people of South Asian origin. This highlights a significant morbidity due to painful neuropathy and identifies key groups who warrant screening for PDN.

Full Text Available Abstract Background Little is known about the prevalence of latent tuberculosis infections (LTBI in health care workers (HCW in low-incidence countries especially in hospitals for pulmonary diseases. With Interferon-gamma release assays (IGRA, a new method for diagnosis of LTBI is available which is more specific than the tuberculin skin test (TST. Objectives The study was designed to estimate prevalence of LTBI among 270 HCW in a Hospital of Pulmonary Diseases routinely screened for TB. Methods LTBI was assessed by the QuantiFERON-Gold In Tube (QFT-IT. Information on gender, age, workplace, job title, BCG vaccination and history of both TB and TST were collected using a standardised questionnaire. Adjusted odds ratios for potential risk factors for LTBI were calculated. Results The prevalence of LTBI was 7.2%. In HCW younger than 30 years LTBI prevalence was 3.5% and in those older than 50 years 22%. Physicians and nurses showed a higher prevalence rate than other professions (10.8% to 4.5%. The putative risk factors for LTBI were age (>50 year OR 9.3, 95%CI 2.5–33.7, working as physicians/nurses (OR 3. 95%CI 1.2–10.4 and no previous TST in medical history (OR 4.4, 95%CI 1.01–18.9 when compared to those with a negative TST. Conclusion Prevalence of LTBI assessed by QFT-IT is low, this indicates a low infection risk even in hospitals for pulmonary diseases. No statement can be made regarding the occupational risk as compared to the general population because there are no LTBI prevalence data from Germany available. The higher LTBI prevalence rate in older HCWs might be due to the cohort effect or the longer time at risk.

Dwellers of urban informal settlements in developing countries are consistently reported to be victims of high diarrhoea prevalence. Studies have frequently reported the association between high diarrhoea prevalence and other factors, such as poor living conditions, inadequate hygiene, and sanitation in these settings. However, little is known about the dynamics of diarrhoea prevalence in mountainous urban informal settlements similar to the Rwandan context. This study was conducted in the Matyazo cell of Huye town to review the prevalence and correlates of diarrhoea. A survey of 214 households and transect walks in the neighbourhoods were conducted during the rainy and dry seasons. Logistic regression was used to analyse the survey data while the thematic analysis technique was used to analyse qualitative data. Results indicated a substantial reduction of diarrhoea prevalence from the rainy to the dry season. It was also found that the prevalence was unequally distributed in the neighbourhoods according to household location. After controlling for other household characteristics and sanitation conditions of around homes, the study indicated that households established at 1800 metres or more above sea level were protected against diarrhoea during both rainy seasons (Adjusted Odds Ratio_ AOR: .42, 95% Confidence Interval_ CI: .13-.81) and dry seasons (AOR: .58, CI: .12-.90) while households found further from the road were likely to suffer from diarrhoea during rainy seasons (AOR: 3.32, CI: 1.47-7.48) as well as in dry seasons (AOR: 1.60, CI: 1.26-4.10). Poor sanitation within and around homes was also found to be associated with the increase of diarrhoea in either season. However, the evidence was not sufficient enough to confirm a significant association between diarrhoea prevalence and other household characteristics. We believe this is due to the strength of environmental factors in mountainous settings.
