    This article asks the question: How well versed are school librarians on issues related to labeling and rating systems? As school librarians continue to design and implement resource location schemes to assist patrons, they must recognize the difference between using labels to create interest in books or implementing labeling and rating systems…

    To examine the relationship between body mass index (BMI) and metabolic syndrome for Asian Americans and non-Hispanic Whites (NHWs), given that existing evidence shows racial/ethnic heterogeneity exists in how BMI predicts metabolic syndrome. Electronic health records of 43,507 primary care patients aged 35 years and older with self-identified race/ethnicity of interest (Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese or NHW) were analyzed in a mixed-payer, outpatient-focused health-care organization in the San Francisco Bay Area. Metabolic syndrome prevalence is significantly higher in Asians compared with NHWs for every BMI category. For women at the mean age of 55 and BMI of 25  kg  m(-2), the predicted prevalence of metabolic syndrome is 12% for NHW women compared with 30% for Asians; similarly for men, the predicted prevalence of metabolic syndrome is 22% for NHWs compared with 43% of Asians. Compared with NHW women and men with a BMI of 25  kg  m(-2), comparable prevalence of metabolic syndrome was observed at BMI of 19.6  kg  m(-2) for Asian women and 19.9  kg  m(-2) for Asian men. A similar pattern was observed in disaggregated Asian subgroups. In spite of the lower BMI values and lower prevalence of overweight/obesity than NHWs, Asian Americans have higher rates of metabolic syndrome over the range of BMI. Our results indicate that BMI ranges for defining overweight/obesity in Asian populations should be lower than for NHWs.

    The diagnosis and epidemiology of acute respiratory tract infection (ARI) in 199 children less than 5 years old were investigated in Manila. As part of this study, children who were treated at one of two outpatient clinics for cough of less than 3 weeks' duration were studied to test the validity of the use of a respiratory rate (RR) of greater than 50/minute for identifying ARI of a severity necessitating treatment with antibiotics. In the first population, in which 69% of the children had radiologically confirmed pneumonia, the sensitivity of a RR of greater than 50/minute was 54%, the specificity was 84%, the false-positive rate was 16%, and the false-negative rate was 46%. In the second population, in which 29% of the children had pneumonia, the sensitivity and positive predictive values were low. The validity of a RR of greater than 50/minute may vary in populations with different prevalences of ARI.

    Hyperthyroidism is common in older cats. Prevalence varies geographically, but is anecdotally considered low in Ireland. The aim of this study was to document prevalence of hyperthyroidism in older cats in the greater Dublin area of Ireland and to assess environmental and clinical associations for development and identification of the disease. Primary-care veterinary practices were requested to select cats aged 10 years or older where blood sampling was being performed for health screening or clinical investigations. Surplus serum/plasma samples were submitted to University College Dublin Diagnostic Endocrine Laboratory for total thyroxine (T 4 ) measurement. Cats were classified as hyperthyroid, equivocal or euthyroid based on a total T 4 concentration (reference interval, 15-60 nmol/L), of >60 nmol/L, 30-60 nmol/L or hyperthyroidism were excluded. A questionnaire completed by the client and veterinarian detailing historical and physical information was also required. Associations between categorical variables were analysed by Chi-square or Fisher's exact test and odds ratio (OR) calculated. A P value of hyperthyroid, 54 (10.6%) equivocal and 346 (68.2%) euthyroid. The presence of goitre ( P  weight loss ( P  hyperthyroidism. Cats with goitre were more likely to be diagnosed as hyperthyroid [OR 2.85, (95% CI 1.75-4.62] compared to those without. However, goitre was only palpated in 40 of 102 (39.2%) hyperthyroid cats. Increasing age was the only significant ( P  hyperthyroidism. A relationship between hyperthyroidism and sex, breed, lifestyle, parasite control, vaccination status or feeding habits was not identified. Hyperthyroidism is not uncommon in Irish cats. Age was the only significant risk factor for its development. The high proportion of hyperthyroid cats without palpable goitre (> 60%) may reflect failure to detect goitre and account for the perceived low prevalence of this condition in Ireland.

    Full Text Available Toxocariosis and ancylostomosis remain the most important parasitic infections affecting companion animals worldwide and pose a risk to animal and human health. Information on these infections in dogs in Ghana is inadequate. A cross sectional study was undertaken to determine the occurrence of gastrointestinal helminths infections and management practices of dogs in the Greater Accra Region (GAR of Ghana. Faecal samples were obtained from 380 dogs from communities in 11 out of 16 districts in the GAR. Coprological examination of the samples was performed using the modified McMaster technique. Management practices for control of helminths in dogs were assessed through questionnaire interviews of the dog owners. Most dogs (70.7% were kept for security reasons and were not housed (61.8%. Prevalence of gastrointestinal helminths was 62.6%. Hookworm eggs were found in 178 (46.8% dogs, Toxocara canis eggs in 22 (5.8% and mixed infections of hookworms and T. canis in 38 (10.0%. Dipylidium caninum was found in 51 (13.4% dogs, while Isospora species was in 33 (8.5% dogs. Most households (68%; 133/194 of the sampled dogs had at least a child below the age of 5 years. Hookworm, T. canis and D. caninum were the zoonotic gastrointestinal helminths prevalent in dogs in the study area. Lack of housing for dogs creates ideal conditions for infection and spread of the zoonotic parasites.

    Full Text Available Aim: This study was conducted for determination of the prevalence of colibacillosis in chicken in poultry farms in Mymensingh and Tangail districts. Isolation, identification, and antibiogram profile of Escherichia coli were also performed. Materials and Methods: A total of 25 chickens manifested clinical signs of colibacillosis were collected from five different poultry farms during natural outbreaks. Results: In broiler, the prevalence of colibacillosis was 0.84%, and in layer, prevalence was 0.80%. The prevalence of colibacillosis was 1.0% and 0.5% in 25-30 days old and 31-35 days old broiler, respectively. In case of layer birds, the prevalence was 0.6% in 40-45 days old bird and 1% in 46-50 days old bird. Identity of the E. coli isolate of chicken was confirmed by sugar fermentation, biochemical tests, and polymerase chain reaction assay. Antibiogram profile of E. coli isolate of chicken revealed that it was multidrug resistant (resistant against two antibiotics, such as ampicillin and cefalexin. Conclusion: Data of this study suggest that colibacillosis is prevalent in the study areas which underscore the need of implementation of prevention and control measure against this disease.

    Conclusion: Asthma prevalence in this low‐humidity environment was lower, but more severe than those reported in other Brazilian cities. The dry climate might hamper disease control and this may have contributed to the higher school absenteeism observed. The association of asthma with allergic rhinitis and atopic dermatitis as well as a history of asthma in parents suggests that atopy is an important risk factor for asthma in this population.

    We simultaneously monitored the heart rate and behavior of nine free-living Greater White-fronted Geese (Anser albifrons) on their wintering grounds in northern California. Heart rates of wild geese were monitored via abdominally-implanted radio transmitters with electrodes that received electrical impulses of the heart and emitted a radio signal with each ventricular contraction. Post-operative birds appeared to behave normally, readily rejoining flocks and flying up to 15 km daily from night-time roost sites to feed in surrounding agricultural fields. Heart rates varied significantly among individuals and among behaviors, and ranged from less than 100 beats per minute (BPM) during resting, to over 400 BPM during flight. Heart rates varied from 80 to 140 BPM during non-strenuous activities such as walking, feeding, and maintenance activities, to about 180 BPM when birds became alert, and over 400 BPM when birds were startled, even if they did not take flight. Postflight heart rate recovery time averaged postures, as heart rates were context-dependent, and were highest in initial encounters among individuals. Instantaneous measures of physiological parameters, such as heart rate, are often better indicators of the degree of response to external stimuli than visual observations and can be used to improve estimates of energy expenditure based solely on activity data.

    Objective High rates of mental disorders have been reported for prison populations worldwide, particularly in low- and middle-income countries (LMICs). The present study aimed to establish prevalence rates of mental disorders in Chilean prisoners. Method A nationwide random sample of 1008 prisoners was assessed in 7 penal institutions throughout Chile. Twelve-month prevalence rates were established using the Composite International Diagnostic Interview (CIDI) and compared to the prevalence rates previously published for the general population. Results Prevalence rates were 12.2% (95% CI, 10.2-14.1) for any substance use disorder, 8.3% (6.6-10.0) for anxiety disorders, 8.1% (6.5-9.8) for affective disorders, 5.7% (4.4-7.1) for intermittent explosive disorders, 2.2% (1.4-3.2) for ADHD of the adult, and 0.8% (0.3-1.3) for non-affective psychoses. Significantly higher prevalence rates among prisoners as compared to the general population in Chile were seen for major depression (6.1% vs. 3.7% males, Z=2.58, pprison population than in the general population. One-year prevalence rates of alcohol abuse (2.3% vs. 3.9%; Z=-2.04; pprison population than in the general population. Conclusions Service provision for prison populations in Chile should acknowledge high rates of depression and illicit drug use. Overall prevalence rates are lower than reported in other LMICs. Previous research in prison populations in LMICs might have overestimated prevalence rates of mental disorders. PMID:23894415

    Full Text Available Background: Management of patients suffering from tuberculosis (TB after discharge from hospital plays a critical role in the cure rate of TB. Despite interventions developed by the World Health Organization (WHO to improve the cure rate, TB remains a worldwide health problem. Objective: The purpose of the study was to explore and describe the views of professional nurses regarding the low TB cure rate in primary healthcare facilities of Greater Giyani Municipality in Limpopo Province, South Africa, with the aim of determining strategies that can be used to improve this low rate. Method: This study was qualitative, exploratory, descriptive and contextual in nature. The population consisted of professional nurses working in primary healthcare facilities within Greater Giyani Municipality, which has a TB cure rate below the national target of 85 %. Data gathering was through individual face-to-face interviews using an interview guide. Open-coding was used to analyse the data in this study. Results: The theme that emerged from data was ‘factors contributing to low TB cure rate’. This theme was supported by the following sub-themes: poor referral system, lack of knowledge about TB and its treatment, stigma attached to TB, and cultural and religious beliefs. The professional nurses suggested counselling of TB patients upon diagnosis, advice about patients’ responsibilities and the involvement of family members. Conclusion: The involvement of community stakeholders in TB prevention, health promotion and education activities devoted to disease spread and cure is vital so that the stigma attached to TB can be eliminated. TB education and awareness programmes should be included in the curriculum of primary schools.

    Several surveys have documented the increasing population size and geographic distribution of Eastern Population greater sandhill cranes Grus canadensis tabida since the 1960s. Sport hunting of this population of sandhill cranes started in 2012 following the provisions of the Eastern Population Sandhill Crane Management Plan. However, there are currently no published estimates of Eastern Population sandhill crane survival rate that can be used to inform harvest management. As part of two studies of Eastern Population sandhill crane migration, we deployed solar-powered global positioning system platform transmitting terminals on Eastern Population sandhill cranes (n  =  42) at key concentration areas from 2009 to 2012. We estimated an annual survival rate for Eastern Population sandhill cranes from data resulting from monitoring these cranes by using the known-fates model in the MARK program. Estimated annual survival rate for adult Eastern Population sandhill cranes was 0.950 (95% confidence interval  =  0.885–0.979) during December 2009–August 2014. All fatalities (n  =  5) occurred after spring migration in late spring and early summer. We were unable to determine cause of death for crane fatalities in our study. Our survival rate estimate will be useful when combined with other population parameters such as the population index derived from the U.S. Fish and Wildlife Service fall survey, harvest, and recruitment rates to assess the effects of harvest on population size and trend and evaluate the effectiveness of management strategies.

    Osteochondrosis (OC) is common in large-breed dogs. According to the breeding guidelines of the Swiss kennel clubs, the shoulder joints are included in the radiographic screening for joint diseases in the Greater Swiss Mountain dog (GSMD) and the Border Collie (BC) since 1993 and 2003, respectively. The aim of this study was to estimate the overall prevalence of humeral head OC in these 2 breeds in Switzerland based on the data of the Swiss National Dysplasia Committees. All radiographs were re-evaluated to assess single radiographic changes. From 1993 and 2003, accordingly, until 2013, the overall prevalence was 14% for the GSMD and 8% for the BC, respectively. Affected joints showed a focally reduced opacity or a flattened/indented contour of the caudal section of the humeral head. Articular flaps were only seen occasionally. Degenerative joint disease was significantly more common in OC affected joints (GSMD: 32%; BC: 20%) than in joints without OC. The present study is the first report on the prevalence of humeral head OC in a large cohort of GSMD and the BC over a long study period. In comparison to other breeds, the herein reported prevalences are in the mid to upper range. Results of the present study should alert veterinarians to the disease in these breeds and may serve as a starting point for further epidemiological and genetic studies.

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

    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

    H.H. Janzen (2006) eloquently argued that from an agricultural perspective there is a tradeoff between storing carbon as soil organic matter (SOM) and the soil nutrient and energy benefit provided during SOM mineralization. Here we report on results from the Permanent Rotation Trial at the Waite Agricultural Institute, South Australia, indicating that shifting to an agricultural management strategy which returns more carbon to the soil, not only leads to greater carbon stocks but also increases the rate of carbon cycling through the soil. The Permanent Rotation Trial was established on a red Chromosol in 1925 with upgrades made to several treatments in 1948. Decadal soil samples were collected starting in 1963 at two depths, 0-10 and 10-22.5 cm, by compositing 20 soil cores taken along the length of each plot. We have chosen to analyze five trials representing a gradient in productivity: permanent pasture (Pa), wheat-pasture rotation (2W4Pa), continuous wheat (WW), wheat-oats-fallow rotation (WOF) and wheat-fallow (WF). For each of the soil samples (40 in total), the radiocarbon activity in the bulk soil as well as size-fractionated samples was measured by accelerator mass spectrometry at ANU's Radiocarbon Dating Laboratory (Fallon et al. 2010). After nearly 70 years under each rotation, SOC stocks increased linearly with productivity data across the trials from 24 to 58 tC ha-1. Importantly, these differences were due to greater losses over time in the low productivity trials rather than gains in SOC in any of the trials. Uptake of the bomb-spike in atmospheric 14C into the soil was greatest in the trials with the greatest productivity. The coarse size fraction always had greater Δ14C values than the bulk soil samples. Several different multi-pool steady state and non-steady state models were used to interpret the Δ14C data in terms of SOC turnover rates. Regardless of model choice, either the decay rates of all pools needed to increase or the allocation of C to

    The aim of this study was to estimate the prevalence of chronic overuse pain (COP) and to identify possible risk factors of COP in sport poomsae taekwondo. This is a cross-sectional survey. A total of 263 sport-poomsae competitors (112 females; 151 males; aged between 12-44 years), who competed at the 2014 sport poomsae taekwondo competition, participated in this study. The prevalence rate of COP and possible risk factors associated with COP were analyzed by using Chi-square tests and independent t-tests. A total of 173 athletes reported that they experienced COP (65.8%; 95% confidence interval [CI]: 60.5-71.5). Female athletes showed a higher prevalence rate than their male counterparts (75.9% vs. 58.3%). Lower body (61.5%) and knee joints (26.4%) were the two primarily injured body part. A total of 101 athletes reported that they injured in the previous year. Among those, 81.2% were suffered from COP. The technique that caused pain most frequently was side-kick among females and front-kick among males. Prevalence rates of COP were significantly different by sex, education level, training hour, and a history of injury. The prevalence of COP is high among sport poomsae taekwondo athletes. Competitors who are female, have a history of injury, and train for extended hours were more likely to experience COP. To identify other potential risk factors of COP in sport poomsae taekwondo, more research is needed to build upon the findings.

    To estimate and interpret differences in depression prevalence rates among industries, using a large, group medical claims database. Depression cases were identified by ICD-9 diagnosis code in a population of 214,413 individuals employed during 2002-2005 by employers based in western Pennsylvania. Data were provided by Highmark, Inc. (Pittsburgh and Camp Hill, PA). Rates were adjusted for age, gender, and employee share of health care costs. National industry measures of psychological distress, work stress, and physical activity at work were also compiled from other data sources. Rates for clinical depression in 55 industries ranged from 6.9 to 16.2 %, (population rate = 10.45 %). Industries with the highest rates tended to be those which, on the national level, require frequent or difficult interactions with the public or clients, and have high levels of stress and low levels of physical activity. Additional research is needed to help identify industries with relatively high rates of depression in other regions and on the national level, and to determine whether these differences are due in part to specific work stress exposures and physical inactivity at work. Claims database analyses may provide a cost-effective way to identify priorities for depression treatment and prevention in the workplace.

    Full Text Available BackgroundThe incubus phenomenon is a paroxysmal sleep-related disorder characterized by compound hallucinations experienced during brief phases of (apparent wakefulness. The condition has an almost stereotypical presentation, characterized by a hallucinated being that exerts pressure on the thorax, meanwhile carrying out aggressive and/or sexual acts. It tends to be accompanied by sleep paralysis, anxiety, vegetative symptoms, and feelings of suffocation. Its prevalence rate is unknown since, in prior analyses, cases of recurrent isolated sleep paralysis with/without an incubus phenomenon have been pooled together. This is unfortunate, since the incubus phenomenon has a much greater clinical relevance than isolated sleep paralysis.MethodsPubMed, Embase, and PsycINFO were searched for prevalence studies of the incubus phenomenon, and a meta-analysis was performed.ResultsOf the 1,437 unique records, 13 met the inclusion criteria, reporting on 14 (k independent prevalence estimates (total N = 6,079. The pooled lifetime prevalence rate of the incubus phenomenon was 0.19 [95% confidence interval (CI = 0.14–0.25, k = 14, N = 6,079] with heterogeneous estimates over different samples. In selected samples (e.g., patients with a psychiatric disorder, refugees, and students, prevalence rates were nearly four times higher (0.41, 95% CI = 0.25–0.56, k = 4, n = 1,275 than in the random samples (0.11, 95% CI = 0.08–0.14, k = 10, n = 4,804. This difference was significant (P < 0.001.ConclusionThis review and meta-analysis yielded a lifetime prevalence of the incubus phenomenon in the general population of 0.11 and, in selected samples, of 0.41. This is slightly higher than the prevalence rates in previous analyses that included cases of recurrent isolated sleep paralysis without an incubus phenomenon. Based on the condition’s robust clinical presentation and the relatively high prevalence rates, we advocate

    An excessive, problematic gambling pattern has been regarded as a mental disorder in the Diagnostic and Statistical Manual for Mental Disorders (DSM) for more than 3 decades (American Psychiatric Association [APA], 1980). In this study, its latest prevalence in Macao (one of very few cities with legalized gambling in China and the Far East) was estimated with 2 major changes in the diagnostic criteria, suggested by the 5th edition of DSM (APA, 2013): (a) removing the "Illegal Act" criterion, and (b) lowering the threshold for diagnosis. A random, representative sample of 1,018 Macao residents was surveyed with a phone poll design in January 2013. After the 2 changes were adopted, the present study showed that the estimated prevalence rate of gambling disorder was 2.1% of the Macao adult population. Moreover, the present findings also provided empirical support to the application of these 2 recommended changes when assessing symptoms of gambling disorder among Chinese community adults. Personal risk factors of gambling disorder, namely being male, having low education, a preference for casino gambling, as well as high materialism, were identified.

    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.

  10. Accelerated decay rates drive soil organic matter persistence and storage in temperate forests via greater mineral stabilization of microbial residues.

    Climate predicts soil organic matter (SOM) stocks at the global scale, yet controls on SOM stocks at finer spatial scales are still debated. A current hypothesis predicts that carbon (C) and nitrogen (N) storage in soils should be greater when decomposition is slow owing to microbial competition for nutrients or the recalcitrance of organic substrates (hereafter the `slow decay' hypothesis). An alternative hypothesis predicts that soil C and N storage should be greater in soils with rapid decomposition, owing to the accelerated production of microbial residues and their stabilization on soil minerals (hereafter the `stabilization hypothesis'). To test these alternative hypotheses, we quantified soil C and N to 1-m depth in temperate forests across the Eastern and Midwestern US that varied in their biotic, climatic, and edaphic properties. At each site, we sampled (1) soils dominated by arbuscular mycorrhizal (AM) tree species, which typically have fast decay rates and accelerated N cycling, (2) soils dominated by ectomycorrhizal (ECM) tree species, which generally have slow decay rates and slow N cycling, and (3) soils supporting both AM and ECM trees. To the extent that trees and theor associated microbes reflect and reinforce soil conditions, support for the slow decay hypothesis would be greater SOM storage in ECM soils, whereas support for the stabilization hypothesis would be greater SOM storage in AM soils. We found support for both hypotheses, as slow decomposition in ECM soils increased C and N storage in topsoil, whereas fast decomposition in AM soils increased C and N storage in subsoil. However, at all sites we found 57% greater total C and N storage in the entire profile in AM- soils (P stabilization hypothesis. Amino sugar biomarkers (an indicator of microbial necromass) and particle size fractionation revealed that the greater SOM storage in AM soils was driven by an accumulation of microbial residues on clay minerals and metal oxides.

    HIV/AIDS is a worldwide threat to human health with mortality, prevalence, and incidence rates varying widely. We evaluated the association between the global HIV/AIDS epidemic and national socioeconomic development. We obtained global age-standardized HIV/AIDS mortality, prevalence, and incidence rates from World Health Statistics Report of the World Health Organization. The human development indexes (HDIs) of 141 countries were obtained from a Human Development Report. Countries were divided into 4 groups according to the HDI distribution. We explored the association between HIV/AIDS epidemic and HDI information using Spearman correlation analysis, regression analysis, and the Kruskal-Wallis test. HIV/AIDS mortality, prevalence, and incidence rates were inversely correlated with national HDI (r = -0.675, -0.519, and -0.398, respectively; P birth, mean years of schooling, expected years of schooling, and gross national income per capita). Low HDI countries had higher HIV/AIDS mortality, prevalence, and incidence rates than that of medium, high, and very high HDI countries. Quantile regression results indicated that HDI had a greater negative effect on the HIV/AIDS epidemic in countries with more severe HIV/AIDS epidemic. Less-developed countries are likely to have more severe HIV/AIDS epidemic. There is a need to pay more attention to HIV/AIDS control in less-developed countries, where lower socioeconomic status might have accelerated the HIV/AIDS epidemic more rapidly.

    To examine the association of acculturation with various cardiovascular risk factors (CRFs) among Latinos with diabetes in South Florida. In a cross-sectional analysis of data collected from 300 Latinos with poorly controlled diabetes we measured acculturation using the Marin Short Acculturation Scale. We examined correlations between acculturation and the following 7 CRFs: hemoglobin A1C, low-density lipoprotein, systolic blood pressure, body mass index, smoking status, physical activity, and fruit and vegetable intake. Cubans made up 38% of our population; no other Latino subgroup represented over 17% of the sample. Of the 8 outcomes examined, only smoking was associated with increased acculturation; 12% of Latinos in the 2 lowest acculturation groups were current smokers versus 25% in the highest acculturation group (P=0.02). Furthermore, Cuban Americans from our sample had over double the prevalence of smoking compared with non-Cubans in both the lowest and highest acculturation groups. With the exception of smoking, our data does not support a link between increased acculturation and higher prevalence of CRFs in Latinos with diabetes. Smoking prevention and cessation programs targeting Latinos and particularly among Cubans are needed.

  13. Analysis of self-reported versus biomarker based smoking prevalence: methodology to compute corrected smoking prevalence rates.

    Prevalence of smoking is needed to estimate the need for future public health resources. To compute and compare smoking prevalence rates by using self-reported smoking statuses, two serum cotinine (SCOT) based biomarker methods, and one urinary 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) based biomarker method. These estimates were then used to develop correction factors to be applicable to self-reported prevalences to arrive at corrected smoking prevalence rates. Data from National Health and Nutrition Examination Survey (NHANES) for 2007-2012 for those aged ≥20 years (N = 16826) were used. Self-reported prevalence rate for the total population computed as the weighted number of self-reported smokers divided by weighted number of all participants was 21.6% and 24% when computed by weighted number of self-reported smokers divided by the weighted number of self-reported smokers and nonsmokers. The corrected prevalence rate was found to be 25.8%. A 1% underestimate in smoking prevalence is equivalent to not being able to identify 2.2 million smokers in US in a given year. This underestimation, if not corrected, could lead to serious gap in the public health services available and needed to provide adequate preventive and corrective treatment to smokers.

    Full Text Available Aim: Supernumerary teeth are considered as one of the most significant dental anomalies during the primary and early mixed dentition stage. The main objective of the study was to determine the prevalence rate of supernumerary teeth in the patients who reported to the Department of Oral Medicine and Radiology and to study the associated clinical complications. Materials and Methods: A longitudinal observational study was conducted of 2216 patients for a period of 4 months with the documentation of demographic data, the presence of supernumerary teeth, their location, and associated complications such as mechanical trauma, dental caries, and associated pathology. Results: The study recorded 27 supernumerary teeth from the examined 2216 patients. This yields a prevalence of 1.2%, with greater frequency in males which was 1.49% and in females the frequency was 0.85%. The greatest proportion of supernumerary teeth was found in the maxillary anterior region (77.8%. Out of this, 85.7% were classified as mesiodens based on their location. The displacement of adjacent teeth was the most common finding, followed by dental caries. Conclusion: The prevalence of supernumerary teeth in this study was 1.2% which is in agreement with that reported in similar studies and the maxillary mesiodens was the most common location. Displacement of adjacent teeth was the most common finding.

    Full Text Available Asthma remains poorly studied in homeless children. We sought to estimate the prevalence of asthma-like symptoms (ALS and to identify the factors associated with ALS and healthcare service utilisation.A cross-sectional survey of a random sample of sheltered homeless families was conducted by interviewing 801 parents of children (0-12 years in 17 languages. ALS were defined as wheezing or night cough without fever during the previous year. Poisson regression models with robust error variance were used to compute prevalence ratios (PR for factors associated with ALS and healthcare service utilisation for ALS.The prevalence of ALS among the children was 19.9%. Poor housing sanitation was significantly associated with ALS, as being born in the European Union. Most of the children with ALS had used healthcare services (85.4%. The main barriers to accessing such services were having lived in France for less than 49 months, having difficulties in French and living in poor housing conditions.ALS prevalence seemed lower than in the general child population, possibly because of the children's origins. Environmental factors associated with ALS point to the need to improve the indoor environment of family shelters. The relatively high rate of healthcare service utilisation should not overshadow existing barriers.

    2014-10-01

    To investigate the relationship between smoking rate and periodontal disease prevalence in Sweden. National smoking rates were found from Swedish National Statistics on smoking habits. Based on smoking rates for the years 1970-2010, periodontal disease prevalence estimates were calculated for the age bracket 40-70 years and smoking-associated relative risks between 2.0 and 20.0. The impact of smoking on the population was estimated according to the concept of population attributable fraction. The age-standardized smoking rate in Sweden declined from 44% in 1970 to 15% in 2010. In parallel with the smoking decline the calculated prevalence estimate of periodontal disease dropped from 26% to 12% assuming a 10-fold smoking-associated relative risk. Even at more moderate magnitudes of the relative risk, e.g. 2-fold or 5-fold, the prevalence decrease was quite tangible, suggesting that the current prevalence in Sweden is about 20-50% of the level 40 years ago. The population attributable fraction, estimating the portion of the disease that would have been avoided in the absence of smoking, was 80% in 1970 and 58% in 2010 at a ten-fold relative risk. Calculated estimates of periodontal disease prevalence are closely related to real changes in smoking rate. As smoking rate drops periodontal disease prevalence will drop. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Background Usage of online resources by clinicians in training and practice can provide insight into knowledge gaps and inform development of decision support tools. Although online information seeking is often driven by encountered patient problems, the relationship between disease prevalence and search rate has not been previously characterized. Objective This article aimed to (1) identify topics frequently searched by pediatric clinicians using UpToDate (http://www.uptodate.com) and (2) explore the association between disease prevalence rate and search rate using data from the Pediatric Health Information System. Methods We identified the most common search queries and resources most frequently accessed on UpToDate for a cohort of 18 children's hospitals during calendar year 2012. We selected 64 of the most frequently searched diseases and matched ICD-9 data from the PHIS database during the same time period. Using linear regression, we explored the relationship between clinician query rate and disease prevalence rate. Results The hospital cohort submitted 1,228,138 search queries across 592,454 sessions. The majority of search sessions focused on a single search topic. We identified no consistent overall association between disease prevalence and search rates. Diseases where search rate was substantially higher than prevalence rate were often infectious or immune/rheumatologic conditions, involved potentially complex diagnosis or management, and carried risk of significant morbidity or mortality. None of the examined diseases showed a decrease in search rate associated with increased disease prevalence rates. Conclusion This is one of the first medical learning needs assessments to use large-scale, multisite data to identify topics of interest to pediatric clinicians, and to examine the relationship between disease prevalence and search rate for a set of pediatric diseases. Overall, disease search rate did not appear to be associated with hospital

    Vietnam has an emerging human immunodeficiency virus (HIV) epidemic (estimated population prevalence 0.5%), but valid data on HIV prevalence among tuberculosis (TB) patients are limited. Recent increases in TB notification rates among young adults may be related to HIV. To assess the prevalence of HIV infection among smear-positive TB patients in six provinces with relatively high HIV population prevalence in Vietnam. All patients who registered for treatment of smear-positive TB during the fourth quarter of 2005 were offered HIV testing. Of the 1217 TB patients included in the study, 100 (8.2%) tested HIV-positive. HIV prevalence varied between 2% and 17% in the provinces, and was strongly associated with age Vietnam, HIV infection is concentrated in drug users, as well as in specific geographic areas where it has considerable impact on TB notification rates among men aged 15-34 years.

    Some evidence suggests that prevalence of celiac disease in the general population is increasing over time. Because the prognosis of celiac disease was a dismal one before discovering the role of gluten, our aim was to investigate a possible relationship between children under-5 mortality rates and prevalence rates of celiac disease. Thanks to a literature review, we found 27 studies performed in 17 different countries describing the prevalence of celiac disease in schoolchildren; between 1995 and 2011, 4 studies were performed in Italy. A meta-analysis of prevalence rates was performed. Prevalence was compared between specific country under-5 mortality groups, publication year, and age. In the last decades, under-5 mortality rates have been decreasing all over the world. This reduction is paralleled by an increase of the prevalence of celiac disease. The Spearman correlation coefficient was -63%, 95% confidence interval -82% to -33% (P celiac disease in the general population. In the near future, the number of patients with celiac disease will increase, thanks to the better environmental conditions that nowadays allow a better survival of children with celiac disease.

    Individuals involved in the criminal justice system have disproportionately high rates of psychiatric disorders when compared to the general U.S. If left untreated, the likelihood of subsequent arrest increases and risk for adverse health consequences is great, particularly among opioid users. To explore the prevalence, characteristics, and treatment of mood disorders among justice involved opioid-dependent populations. The current study enrolled 258 treatment-seeking opioid-dependent individuals under community-based criminal justice supervision (e.g., probation, parole) screened from the larger parent study, Project STRIDE, a seek/test/treat randomized control trial (RCT) examining HIV and opioid use treatment. During baseline, individuals were screened for depression using the Patient Health Questionnaire-9 (PHQ-9) and screened for bipolar disorder using the Mood Disorder Questionnaire (MDQ) tool. Overall, 78 (30%) participants screened positive for moderate to severe depression and 54 (21%) screened positive for bipolar disorder. Participants self-reported mood disorders at higher rates than they screened positive for these conditions. Participants screening positive for these conditions experienced significantly greater family, legal, and medical problems on the Addiction Severity Index-Lite (ASI-Lite) than those who did not screen positive. Incidence of a lifetime suicide attempt was found to be associated with a positive screen for both mood disorders. Prescribed psychotropic treatment utilization was similar among those who screened positive for depression or bipolar disorder with approximately 38% reporting taking medication. Findings suggest universal mood disorder screening to improve comprehensive psychiatric care and treatment of opioid-dependent justice-involved individuals.

  7. Does multimorbidity influence the occurrence rates of chronic conditions? A claims data based comparison of expected and observed prevalence rates.

    Directory of Open Access Journals (Sweden)

    Ingmar Schäfer

    Full Text Available OBJECTIVE: Multimorbidity is a complex phenomenon with an almost endless number of possible disease combinations with unclear implications. One important aspect in analyzing the clustering of diseases is to distinguish between random coexistence and statistical dependency. We developed a model to account for random coexistence based on stochastic distribution. We analyzed if the number of diseases of the patients influences the occurrence rates of chronic conditions. METHODS: We analyzed claims data of 121,389 persons aged 65+ using a list of 46 chronic conditions. Expected prevalences were simulated by drawing without replacement from all observed diseases using observed overall prevalences as initial probability weights. To determine if a disease occurs more or less frequently than expected by chance we calculated observed-minus-expected deltas for each disease. We defined clinical relevance as |delta| ≥ 5.0%. 18 conditions were excluded because of a prevalence < 5.0%. RESULTS: We found that (1 two chronic conditions (e.g. hypertension were more frequent than expected in patients with a low number of comorbidities; (2 four conditions (e.g. renal insufficiency were more frequent in patients with many comorbidities; (3 six conditions (e.g. cancer were less frequent with many comorbidities; and (4 16 conditions had an average course of prevalences. CONCLUSION: A growing extent of multimorbidity goes along with a rapid growth of prevalences. This is for the largest part merely a stochastic effect. If we account for this effect we find that only few diseases deviate from the expected prevalence curves. Causes for these deviations are discussed. Our approach also has methodological implications: Naive analyses of multimorbidity might easily be affected by bias, because the prevalence of all chronic conditions necessarily increases with a growing extent of multimorbidity. We should therefore always examine and discuss the stochastic interrelations

    Growth of ground cover and trees was evaluated for five growing seasons on calcareous coal minesoil surfaces (standard graded topsoil, graded and ripped topsoil, graded gray cast overburden) in southeastern Ohio. Soil surface plots were seeded in September 1987 with either a standard herbaceous seed mix [orchardgrass (Dactylis glomerata L.), timothy (Phleum pratense L.), perennial ryegrass (Lolium perenne L.), Kentucky bluegrass (Poa pratensis L.), Ranger alfalfa (Medicago sativa L.), Mammoth red clover (Trifolium pratense L.), Empire birdsfoot trefoil (Lotus corniculatus L.), and wheat (Triticum aestivum L.)], or a modified mix using no alfalfa and half the rate of orchardgrass. Nitrogen (45, 90, or 135 kg ha/N) was applied as ammonium nitrate in September 1987 and April 1989. White ash (Fraxinus americana L.), silver maple (Acer saccharinum L.), northern red oak (Quercus rubra L.), and eastern white pine (Pinus strobus L.) were planted in spring 1989 into 0.8 m-wide strips sprayed with glyphosate herbicide at 2.24 kg/ha in October 1988. Total cover and total biomass were highest in July 1989, following the last application of nitrogen fertilizer in April 1989. Total cover ranged from 44% to 56%, and total biomass ranged from 102 to 162 g/0.5 m 2 from 1990 to 1993. Total cover and total biomass were lower at the lowest nitrogen rate in 1989 only. Type of herbaceous seed mix did not affect growth of ground cover or trees. Overall tree survival was 82.0% the first year but declined to 40.6% after 5 yr. Survival varied significantly among all tree species (3.5% for pine, 22.2% for oak, 38.5% for maple, 98.1% for ash)

    This study examined the prevalence rate of Oppositional Defiant Disorder (ODD) in Malaysian primary school children. In all 934 Malaysian parents and teachers completed ratings of their children using a scale comprising DSM-IV-TR ODD symptoms. Results showed rates of 3.10%, 3.85%, 7.49% and 0.64% for parent, teacher, parent or teacher ("or-rule"), and parent and teacher ("and-rule") ratings, respectively. When the functional impairment criterion was not considered, the rate reported by parents was higher at 13.28%. The theoretical, diagnostic and cultural implications of the findings are discussed.

    Investigate the relationship between dietary acculturation and current self-rated health (SRH) among African immigrants, by country or region of origin. Cross-sectional, mixed-methods design using baseline data from longitudinal study of immigrants granted legal permanent residence May to November, 2003, and interviewed June, 2003 to June, 2004. 2003 New Immigrant Survey. African immigrants from a nationally representative sample (n = 763) averaged 34.7 years of age and 5.5 years' US residency; 56.6% were male, 54.1% were married, 26.1% were Ethiopian, and 22.5% were Nigerian. Current SRH (dependent variable) was measured using 5-point Likert scale questions; dietary acculturation (independent variable) was assessed using a quantitative dietary change scale. Multivariate logistic regression tested the relationship of dietary acculturation with current SRH (α = .05; P food/beverages consumed pre-/post-migration. African immigrants reporting moderate dietary change since arrival in the US had higher odds of poorer SRH status than immigrants reporting low dietary change (odds ratio, 1.903; 95% confidence interval, 1.143-3.170; P = .01). Among most dietary change groups, there was an increase in fast food consumption and decrease in fruit and vegetable consumption. Nutrition educators and public health practitioners should develop targeted nutrition education for African immigrants who are older, less educated, and at increased health risk.

    Mexico diabetes prevalence has increased dramatically in recent years. However, no national incidence estimates exist, hampering the assessment of diabetes trends and precluding the development of burden of disease analyses to inform public health policy decision-making. Here we provide evidence regarding current magnitude of diabetes in Mexico and its future trends. We used data from the Mexico National Health and Nutrition Survey, and age-period-cohort models to estimate prevalence and incidence of self-reported diagnosed diabetes by age, sex, calendar-year (1960-2012), and birth-cohort (1920-1980). We project future rates under three alternative incidence scenarios using demographic projections of the Mexican population from 2010-2050 and a Multi-cohort Diabetes Markov Model. Adult (ages 20+) diagnosed diabetes prevalence in Mexico increased from 7% to 8.9% from 2006 to 2012. Diabetes prevalence increases with age, peaking around ages 65-68 to then decrease. Age-specific incidence follows similar patterns, but peaks around ages 57-59. We estimate that diagnosed diabetes incidence increased exponentially during 1960-2012, roughly doubling every 10 years. Projected rates under three age-specific incidence scenarios suggest diabetes prevalence among adults (ages 20+) may reach 13.7-22.5% by 2050, affecting 15-25 million individuals, with a lifetime risk of 1 in 3 to 1 in 2. Diabetes prevalence in Mexico will continue to increase even if current incidence rates remain unchanged. Continued implementation of policies to reduce obesity rates, increase physical activity, and improve population diet, in tandem with diabetes surveillance and other risk control measures is paramount to substantially reduce the burden of diabetes in Mexico.

    Epidemiologic patterns of malaria infection are governed by environmental parameters that regulate vector populations of Anopheles mosquitoes. The intensity of malaria parasite transmission is normally expressed as the entomologic inoculation rate (EIR), the product of the vector biting rate times the proportion of mosquitoes infected with sporozoite-stage malaria parasites. Malaria transmission intensity in Africa is highly variable with annual EIRs ranging from 1,000 infective bites per person per year. Malaria control programs often seek to reduce morbidity and mortality due to malaria by reducing or eliminating malaria parasite transmission by mosquitoes. This report evaluates data from 31 sites throughout Africa to establish fundamental relationships between annual EIRs and the prevalence of Plasmodium falciparum malaria infection. The majority of sites fitted a linear relationship (r2 = 0.71) between malaria prevalence and the logarithm of the annual EIR. Some sites with EIRs 80%. The basic relationship between EIR and P. falciparum prevalence, which likely holds in east and west Africa, and across different ecologic zones, shows convincingly that substantial reductions in malaria prevalence are likely to be achieved only when EIRs are reduced to levels less than 1 infective bite per person per year. The analysis also highlights that the EIR is a more direct measure of transmission intensity than traditional measures of malaria prevalence or hospital-based measures of infection or disease incidence. As such, malaria field programs need to consider both entomologic and clinical assessments of the efficacy of transmission control measures.

    Docosahexaenoic acid (DHA) is important for brain function, however, the exact amount required for the brain is not agreed upon. While it is believed that the synthesis rate of DHA from α-linolenic acid (ALA) is low, how this synthesis rate compares with the amount of DHA required to maintain brain DHA levels is unknown. The objective of this work was to assess whether DHA synthesis from ALA is sufficient for the brain. To test this, rats consumed a diet low in n-3 PUFAs, or a diet containing ALA or DHA for 15 weeks. Over the 15 weeks, whole body and brain DHA accretion was measured, while at the end of the study, whole body DHA synthesis rates, brain gene expression, and DHA uptake rates were measured. Despite large differences in body DHA accretion, there was no difference in brain DHA accretion between rats fed ALA and DHA. In rats fed ALA, DHA synthesis and accretion was 100-fold higher than brain DHA accretion of rats fed DHA. Also, ALA-fed rats synthesized approximately 3-fold more DHA than the DHA uptake rate into the brain. This work indicates that DHA synthesis from ALA may be sufficient to supply the brain.

    Full Text Available BackgroundNonalbuminuric renal insufficiency is a unique category of diabetic kidney diseases. The objectives of the study were to evaluate prevalent rate of nonalbuminuric renal insufficiency and to investigate its relationship with previous cardiovascular disease (CVD event in Korean patients with type 2 diabetes mellitus (T2DM.MethodsLaboratory and clinical data of 1,067 subjects with T2DM were obtained and reviewed. Study subjects were allocated into four subgroups according to the CKD classification. Major CVD events were included with coronary, cerebrovascular, and peripheral vascular events.ResultsNonalbuminuric stage ≥3 CKD group, when compared with albuminuric stage ≥3 CKD group, had shorter diabetic duration, lower concentrations of glycated hemoglobin, high density lipoprotein cholesterol, and high-sensitivity C-reactive protein, lower prevalent rates of retinopathy and previous CVD, and higher rate of treatment with angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers. Nonalbuminuric stage ≥3 CKD group showed a greater association with prior CVD events than no CKD group; however, albuminuric stage ≥3 CKD group made addition to increase prevalence of prior CVD events significantly when CKD categories were applied as covariates. Association of prior CVD events, when compared with normal estimated glomerular filtration rate (eGFR and nonalbuminuria categories, became significant for declined eGFR, which was higher for eGFR of <30 mL/min/1.73 m2, and albuminuria.ConclusionThe results show that subjects with nonalbuminuric stage ≥3 CKD is significantly interrelated with occurrence of prior CVD events than those with normal eGFR with or without albuminuria. Comparing with normal eGFR and nonalbuminuria categories, the combination of increased degree of albuminuria and declined eGFR is becoming significant for the association of prior CVD events.

    The aim of the study was to analyse the prevalence and distribution of buccally displaced canines (BDCs) in subjects scheduled for orthodontic treatment and to investigate the association between BDC and sagittal, vertical, and transverse dentoskeletal relationships. A study sample of 1852 subjects was examined, and it was divided randomly into two groups. A first group of 252 subjects served as control group: the 'reference' prevalence rates for the examined parameters were calculated in this group. The remaining 1600 subjects comprised the sample from which the experimental BDC group was derived. Presence of unilateral or bilateral maxillary BDC, ANB, and SN GOGn angles for sagittal and vertical skeletal relationships, intercanine and intermolar distances, and tooth crowding at the maxillary arch were recorded for each subject. The statistical significance of differences between the BDC and the control groups in transverse relations and tooth crowding at the upper arch was tested by means of independent sample t-tests. Chi-square tests were performed to compare the prevalence rates of BDC and also sagittal and vertical skeletal features in the two groups. The prevalence rate of BDC was 3.06 per cent with a male-to-female ratio of 1:1. BDC subjects exhibited a significant association with hyperdivergent skeletal relationships (38.8%), reduced maxillary intercanine width, and crowding in the upper arch. The presence of specific dentoskeletal characteristics can be considered as a risk indicator for developing a buccal displacement of upper permanent canines.

    Hypertension is a major global health problem, but prevalence rates vary widely among regions. To determine prevalence, treatment, and control rates of hypertension, we measured conventional blood pressure (BP) and 24-hour ambulatory BP in 6546 subjects, aged 40 to 79 years, recruited from 10 community-dwelling cohorts on 3 continents. We determined how between-cohort differences in risk factors and socioeconomic factors influence hypertension rates. The overall prevalence was 49.3% (range between cohorts, 40.0%-86.8%) for conventional hypertension (conventional BP ≥140/90 mm Hg) and 48.7% (35.2%-66.5%) for ambulatory hypertension (ambulatory BP ≥130/80 mm Hg). Treatment and control rates for conventional hypertension were 48.0% (33.5%-74.1%) and 38.6% (10.1%-55.3%) respectively. The corresponding rates for ambulatory hypertension were 48.6% (30.5%-71.9%) and 45.6% (18.6%-64.2%). Among 1677 untreated subjects with conventional hypertension, 35.7% had white coat hypertension (23.5%-56.2%). Masked hypertension (conventional BP hypertension rates. Higher social and economic development, measured by the Human Development Index, was associated with lower rates of conventional and ambulatory hypertension. In conclusion, high rates of hypertension in all cohorts examined demonstrate the need for improvements in prevention, treatment, and control.

    1986-03-01

    With more than a quarter of its population born overseas, Melbourne, Australia, is rapidly changing from an all-white British outpost to a multicultural, multilingual community. Since the "white" Australian policy was abandoned after World War II, 3 million immigrants from 100 different countries have moved to Australia. Most of the immigrants come from New Zealand, Rhodesia, South Africa, Britain, Ireland, Greece, Turkey, Yugoslavia, Poland, and Indochina. Melbourne is Australia's 2nd largest city and houses 1 out of 5 Australians. Its 1984 population was 2,888,400. Melbourne's housing pattern consists of subdivisions; 75% of the population live in detached houses. Between 1954 and 1961 Melbourne grew at an annual rate of 3.5%; its growth rate between 1961 and 1971 still averaged 2.5%. In the 1970s the growth rate slowed to 1.4%. Metropolitan Melbourne has no central government but is divided into 56 councils and 8 regions. Both Australia's and Melbourne's fertility rates are high compared to the rest of the developed world, partly because of their younger age structure. 41% of Melbourne's population was under age 24 in 1981. Single-person households are growing faster than any other type. 71% of the housing is owner-occupied; in 1981 the median sized dwelling had 5.2 rooms. Public housing only accounts for 2.6% of all dwellings. Fewer students graduate from high school in Australia than in other developed countries, and fewer graduates pursue higher education. Melbourne's suburban sprawl promotes private car travel. In 1980 Melbourne contained more than 28,000 retail establishments and 4200 restaurants and hotels. Industry accounts for 30% of employment, and services account for another 30%. Its largest industries are motor vehicles, clothing, and footware. Although unemployment reached 10% after the 1973 energy crisis, by 1985 it was down to 6%.

    This study examined the prevalence rate of astigmatism and its epidemiological risk factors in Singapore school children. In a study of school children aged 7 to 9 years old in two schools in Singapore in 1999, a detailed questionnaire was administered to parents regarding reading or close-work habits, past history of close-work, family history, and socioeconomic factors. Cycloplegic refraction was performed five times in each eye. Defining astigmatism as worse than or equal to 0.5, 0.75, and 1 D cylinder in the right eye, the prevalence of astigmatism was calculated. The study population consisted of 1028 children. The prevalence rate of astigmatism (worse than or equal to 1 D cylinder) was 19.2% (95% confidence interval, 16.8 to 21.6). This was not different between genders, ethnic groups, or age (p > 0.05). With-the-rule astigmatism was more common than against-the-rule astigmatism. The prevalence of astigmatism and myopia was 9.8% (95% confidence interval, 8.0 to 11.6). A high AC/A ratio was associated (p = 0.003) with astigmatism, even after exclusion of myopic children. On vectorial analysis, J0 and J45 were associated with the number of hours of playing video games, whereas J45 was also associated with computer use. Only J45 was associated to male gender, a high AC/A ratio, and a family history of myopia. The prevalence rate of astigmatism (> or = 1 D) was 19%. Playing video games and computer use may be associated with astigmatism severity, although the presence of astigmatism (> or = 1 D) was not associated with any nearwork factors. A family history of myopia was associated with oblique astigmatism severity. A high AC/A ratio is associated with astigmatism, and this requires further investigation.

  4. Monitoring and prevalence rates of metabolic syndrome in military veterans with serious mental illness.

    Directory of Open Access Journals (Sweden)

    Sameed Ahmed M Khatana

    Full Text Available BACKGROUND: Cardiovascular disease is the leading cause of mortality among patients with serious mental illness (SMI and the prevalence of metabolic syndrome--a constellation of cardiovascular risk factors--is significantly higher in these patients than in the general population. Metabolic monitoring among patients using second generation antipsychotics (SGAs--a risk factor for metabolic syndrome--has been shown to be inadequate despite the release of several guidelines. However, patients with SMI have several factors independent of medication use that predispose them to a higher prevalence of metabolic syndrome. Our study therefore examines monitoring and prevalence of metabolic syndrome in patients with SMI, including those not using SGAs. METHODS AND FINDINGS: We retrospectively identified all patients treated at a Veterans Affairs Medical Center with diagnoses of schizophrenia, schizoaffective disorder or bipolar disorder during 2005-2006 and obtained demographic and clinical data. Incomplete monitoring of metabolic syndrome was defined as being unable to determine the status of at least one of the syndrome components. Of the 1,401 patients included (bipolar disorder: 822; schizophrenia: 222; and schizoaffective disorder: 357, 21.4% were incompletely monitored. Only 54.8% of patients who were not prescribed SGAs and did not have previous diagnoses of hypertension or hypercholesterolemia were monitored for all metabolic syndrome components compared to 92.4% of patients who had all three of these characteristics. Among patients monitored for metabolic syndrome completely, age-adjusted prevalence of the syndrome was 48.4%, with no significant difference between the three psychiatric groups. CONCLUSIONS: Only one half of patients with SMI not using SGAs or previously diagnosed with hypertension and hypercholesterolemia were completely monitored for metabolic syndrome components compared to greater than 90% of those with these characteristics

    Odland, Berthelson, Sharma, Martin, and Mittenberg ( 2013 ) caution that clinically elevated scale scores produced by members of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008 /2011) normative sample raise concerns about the potential for false positive findings of psychopathology. However, the MMPI-2-RF normative sample is intended to represent the general population of the United States, 26.2% of which met criteria for a Diagnostic and Statistical Manual-IV (APA, 1994 ) disorder in a 12-month period (Kessler, Chiu, Demler, & Walters, 2005 ). In the current study we compare scale elevation rates in the MMPI-2-RF normative sample to prevalence rates of mental disorders primarily drawn from the National Comorbidity Study Replication (Kessler et al., 2005 ). Our objective was to evaluate MMPI-2-RF elevation rates in an epidemiological context. Results indicate that MMPI-2-RF scale elevation rates were generally consistent with epidemiological data when examined in the context of standard interpretation guidelines for the inventory. We also reiterate Ben-Porath and Tellegen's (2008/2011) caution that MMPI-2-RF scale elevations alone are not sufficient to indicate the presence of psychiatric disorder. Rather they are best viewed as indications of the need to evaluate the individual for possible disorder(s). Implications of these results, limitations of this study, and future directions in research are discussed.

    Describing the situation of diabetes mellitus (DM) in Spain from a public health perspective. manual review of books and other documents on diabetes mellitus in Spain was conducted. In addition, a specific research of articles published using MeSH terms diabetes mortality, prevalence, incidence, cost, inequalities and Spain was conducted in Medline through Internet (PubMed). Minimun Basic Data Set was utilized as source for complication description by Communities Autonomus. DM is one of the leading cause of mortality and the third one in women. With regard to Autonomous Communities, Canary Islands, Ceuta y Melilla and Andalusia show the greatest mortality with a downward trend. Diabetics present greater mortality than non diabetic patients, being complications the main cause of the over-mortality, especially ischemic heart disease. Estimations of prevalence for DM2 range from 4.8% to 18.7% and for DM1, from .08% to .2%. In pregnancy, it has been noted a prevalence ranging from 4.5% to 16.1%. With respect to incidence per year, it is estimated a range from 146 to 820 per 100,000 inhabitants for DM2 and a range from 10 to 17 new cases annually per 100,000 inhabitants for DM1. Costs for DM1 show very different results, averaging between 1,262 and 3,311 euro per people and year. There are differences for DM2 costs as well, averaging between 381 and 2,560 euro per patient and year. Total costs estimated range from 758 to 4,348 euro per person and year. Relationship between a low socioeconomic level (LSL) and DM2 risk has been proved. Moreover, it has been noted that the less LSL the worse is the disease control, coupled with a greater frequency and more frequent factors of DM2 risk. The knowledge about the situation of the DM as a Public Health problem in Spain is limited. Mortality data available does not gather its real magnitude, and prevalence, incidence, costs and inequalities research are very poor and hardly comparable. In spite of this degree of incertitude, we

    Stroke survivors often exhibit abnormally low motor unit firing rates during voluntary muscle activation. Our purpose was to assess the prevalence of saturation in motor unit firing rates in the spastic-paretic biceps brachii muscle of stroke survivors. To achieve this objective, we recorded the incidence and duration of impaired lower- and higher-threshold motor unit firing rate modulation in spastic-paretic, contralateral, and healthy control muscle during increases in isometric force generated by the elbow flexor muscles. Impaired firing was considered to have occurred when firing rate became constant (i.e., saturated), despite increasing force. The duration of impaired firing rate modulation in the lower-threshold unit was longer for spastic-paretic (3.9 ± 2.2 s) than for contralateral (1.4 ± 0.9 s; P unit was also longer for the spastic-paretic (1.7 ± 1.6 s) than contralateral (0.3 ± 0.3 s; P = 0.007) and control (0.1 ± 0.2 s; P = 0.009) muscles. This impaired firing rate of the lower-threshold unit arose, despite an increase in the overall descending command, as shown by the recruitment of the higher-threshold unit during the time that the lower-threshold unit was saturating, and by the continuous increase in averages of the rectified EMG of the biceps brachii muscle throughout the rising phase of the contraction. These results suggest that impairments in firing rate modulation are prevalent in motor units of spastic-paretic muscle, even when the overall descending command to the muscle is increasing.

    Full Text Available In recent decades the overall smoking prevalence in the US has fallen steadily. This study examines whether the same trend is seen in the Medicaid population.National Health Interview Survey (NHIS data from 17 consecutive annual surveys from 1997 to 2013 (combined N = 514,043 were used to compare smoking trends for 4 insurance groups: Medicaid, the Uninsured, Private Insurance, and Other Coverage. Rates of chronic disease and psychological distress were also compared.Adjusted smoking prevalence showed no detectable decline in the Medicaid population (from 33.8% in 1997 to 31.8% in 2013, trend test P = 0.13, while prevalence in the other insurance groups showed significant declines (38.6%-34.7% for the Uninsured, 21.3%-15.8% for Private Insurance, and 22.6%-16.8% for Other Coverage; all P's<0.005. Among individuals who have ever smoked, Medicaid recipients were less likely to have quit (38.8% than those in Private Insurance (62.3% or Other Coverage (69.8%; both P's<0.001. Smokers in Medicaid were more likely than those in Private Insurance and the Uninsured to have chronic disease (55.0% vs 37.3% and 32.4%, respectively; both P's<0.01. Smokers in Medicaid were also more likely to experience severe psychological distress (16.2% for Medicaid vs 3.2% for Private Insurance and 7.6% for the Uninsured; both P's<0.001.The high and relatively unchanging smoking prevalence in the Medicaid population, low quit ratio, and high rates of chronic disease and severe psychological distress highlight the need to focus on this population. A targeted and sustained campaign to help Medicaid recipients quit smoking is urgently needed.

    Full Text Available BACKGROUND: Tuberculosis (TB transmission in prisons poses significant risks to inmates as well as the general population. Currently, there are no data on smear-negative pulmonary TB cases in prisons and by extension no data on the impact such cases have on TB incidence. This study was designed to obtain initial data on the prevalence of smear-negative cases of TB in prisons as well as preliminary risk factor analysis for such TB cases. METHODS: This cross-sectional survey was conducted in November 2013 at eight main prisons located in the state of Amhara, Ethiopia. Interviews using a structured and pretested questionnaire were done first to identify symptomatic prisoners. Three consecutive sputum samples were collected and examined using acid fast bacilli (AFB microscopy at the point of care. All smear-negative sputum samples were taken for culture and Xpert testing. Descriptive and multivariate analysis was done using SPSS version 16. RESULTS: Overall the prevalence of smear-negative pulmonary TB cases in the study prisons was 8% (16/200. Using multivariate analysis, a contact history to TB patients in prison, educational level, cough and night sweating were found to be predictors of TB positivity among smear-negative pulmonary TB cases (p ≤ 0.05. CONCLUSIONS: In the studied prisons, high prevalence of undiagnosed TB cases using AFB microscopy was documented, which is an important public health concern that urgently needs to be addressed. Furthermore, patients with night sweating, non-productive cough, a contact history with TB patients and who are illiterate merit special attention, larger studies are warranted in the future to assess the associations more precisely. Further studies are also needed to examine TB transmission dynamics by patients with smear-negative pulmonary TB in a prison setting.

    Citizens are on average too pessimistic when assessing the trajectory of current crime trends. In this study, we examine whether we can correct this perceptual bias with respect to burglaries. Using a field experiment coupled with a large panel survey (n=4,895), we explore whether a public...... information campaign can reduce misperceptions about the prevalence of burglaries. Embedding the correct information about burglary rates in a direct mail campaign, we find that it is possible to substantially reduce citizens’ misperceptions. The effects are not short lived – they are detectable several weeks...... after the mailer was sent, but they are temporary. Eventually the perceptual bias re-emerges. Our results suggest that if citizens were continually supplied with correct information about crime rates they would be less pessimistic. Reducing bias in citizens’ perception of crime rates might therefore...

    Full Text Available The purpose of this study is to investigate the prevalence rate and risk factors of depression in outpatients who were diagnosed with PE. Therefore, between September 2009 and September 2011, 1801 outpatients at andrology clinics were enrolled and consented to participate in our survey by completed a verbal questionnaire. It included the following: (1 demographic data (e.g., age, body mass index, (2 PE duration, medical history, and sexual history, (3 self-estimated intravaginal ejaculatory latency times, (4 the Zung Self-rating Depression Scale (SDS, and (5 the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI and (6 the International Index of Erectile Function (IIEF-5. The results showed that a total of 1,206 patients were diagnosed with PE. The prevalence rate of depression in these PE patients was 26.78%. Depression was associated with PE duration, NIH-CPSI score, and IIEF-5 score. Risk factors for depression specifically included PE durations for 13–24, 25–60, or ≥61 months, CPSI scores of 15–30 or ≥31, and IIEF-5 scores <22. These findings suggested that several associated factors (PE duration, CPSI scores, and IIEF-5 scores were the risk factors of depression in men with PE.

    It is known that height and body mass index (BMI) are correlated in childhood. However, its impact on the (trend of) national prevalence rates of overweight and obesity has never been investigated. The aim of our study is to investigate the relation between height and national prevalence rates of overweight and obesity in childhood between 1980, 1997, and 2009, and to calculate which fixed value of p (2.0,2.1, …,3.0) in kg/m(p) during childhood is most accurate in predicting adult overweight. Cross-sectional growth data of children from three Dutch nationwide surveys in 1980, 1997, and 2009, and longitudinal data from the Terneuzen Birth Cohort and the Harpenden Growth Study were used. Relative risks (RR) and 95% confidence intervals (CI) were calculated. Our study showed that tall (>1 standard deviation (SD)) girls aged 5.0-13.9 y were more often overweight (RR = 3.5,95%CI:2.8-4.4) and obese (RR = 3.9,95%CI:2.1-7.4) than short girls (rates of overweight and obesity than their shorter peers. We suggest taking into account the impact of height when evaluating trends and variations of BMI distributions in childhood, and to use BMI to predict adult overweight.

    In order to investigate effects of the A-bombing on prevalence of diabetes mellitus, follow-up studies were made on 5907 A-bomb survivors who received glucose tolerance test (GTT) during 20 years between 1963 and 1983. The A-bomb survivors were divided into the group A (1899 men and 1165 women exposed within 1.9 km from the hypocenter) and the group B (1725 men and 1118 women exposed 3.0 km or farther from it). Among non-obese survivors, 21.9% and 21.8% were being treated for diabetes mellitus or were evaluated as having diabetic type on GTT in the group A and the group B, respectively; while this was seen in 52.1% of obese survivors in the group A and 49.9% in the group B. There was no difference between the groups. In non-obese survivors, the annual development rate from the normal type to the diabetic type was 0.89% in the group A and 0.65% in the group B; the annual development rate from the borderline type to the diabetic type was 5.73% in the group A and 5.49% in the group B, showing no differences between the groups. The annual development rate from the normal or borderline type to the diabetic type was two times or higher in obese survivors than in non-obese survivors irrespective of exposure status. Regarding the number of diabetic survivors who became non-diabetic type in spite of having no treatment, and prevalence of diabetic complications, no difference was seen between the groups. These results suggest that the A-bombing has scarcely influenced the prevalence of diabetes mellitus and clinical course.

    Polycystic ovary syndrome (PCOS) is a heterogeneous syndrome. In vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) is required for PCOS cases that are refractory to standard ovulation induction or have co-existing infertility factors in women with PCOS and Tubal factor subfertility. Assess ethnic variations in response to IVF/ICSI treatment. Observational Comparative study in a University hospital fertility clinic in women with PCOS and Tubal factor subfertility. Women with PCOS (Asians: AP=104; Caucasians: CP=220) and those with tubal factor infertility seeking fertility treatment were assessed (Asians: AC=84; Caucasians: CC=200). Six hundred and eight fresh IVF or ICSI cycles using long protocol of GnRHa suppression and resulting in a fresh embryo transfer were compared. The primary endpoint was to assess the dose of gonadotropins used in the cycles. The secondary outcomes were: total number of oocytes retrieved, fertilization and ongoing clinical pregnancy rates. We found that the South Asian women presented at a younger age for the management of sub-fertility. An extended stimulation phase and Caucasian ethnicity showed an inverse correlation with the number of oocytes retrieved in the PCOS subgroup. Caucasian ethnicity was associated with a higher fertilization rate however increase in body mass index (BMI) and the laboratory technique of IVF appeared to have a negative impact on fertilization rates in the PCOS subgroup. Commencing down regulation on day 1 of the cycles was negatively associated with fertilization rates in the tubal group. In terms of clinical pregnancy rates, the Caucasian PCOS had a 2.5 times (95% CI: 1.25-5) higher chance of an ongoing clinical pregnancy as compared with their Asian counterpart. Also, a unit increase in the basal FSH concentration reduced the odds of pregnancy by 18.6% (95% CI: 1.8-32.6%) in the PCOS group. The Asian PCOS have a greater sensitivity to gonadotropin stimulation with lower fertilization and

    Proposed International Classification of Diseases, 11th edition (ICD-11), criteria for substance use disorder (SUD) radically simplify the algorithm used to diagnose substance dependence. Major differences in case identification across DSM and ICD impact determinations of treatment need and conceptualizations of substance dependence. This study compared the draft algorithm for ICD-11 SUD against DSM-IV, DSM-5, and ICD-10, for alcohol and cannabis. Adolescents (n = 339, ages 14 to 18) admitted to intensive outpatient addictions treatment completed, as part of a research study, a Structured Clinical Interview for DSM SUDs adapted for use with adolescents and which has been used to assess DSM and ICD SUD diagnoses. Analyses examined prevalence across classification systems, diagnostic concordance, and sources of diagnostic disagreement. Prevalence of any past-year proposed ICD-11 alcohol or cannabis use disorder was significantly lower compared to DSM-IV and DSM-5 (ps DSM-5, and ICD-10 (ps DSM-5 SUD diagnoses showed only moderate concordance. For both alcohol and cannabis, youth typically met criteria for an ICD-11 dependence diagnosis by reporting tolerance and much time spent using or recovering from the substance, rather than symptoms indicating impaired control over use. The proposed ICD-11 dependence algorithm appears to "overdiagnose" dependence on alcohol and cannabis relative to DSM-IV and ICD-10 dependence, and DSM-5 moderate/severe use disorder, generating potential "false-positive" cases of dependence. Among youth who met criteria for proposed ICD-11 dependence, few reported impaired control over substance use, highlighting ongoing issues in the conceptualization and diagnosis of SUD.

    Diabetes is a metabolic disease characterized by hyperglycemia, which results from relative or absolute insulin deficiency. One of the first oral symptoms of diabetes is xerostomia. The aim of the study was to determine the prevalence of the xerostomia symptoms and salivary flow rate in diabetic patients according to the type of diabetes, the level of metabolic control and the duration of the disease. The study involved 156 adult patients of both sexes including 34 patients with diabetes type 1 (group C1), 59 with diabetes type 2 (group C2), and 63 generally healthy individuals as two control groups, sex- and age-matched to the diabetic group. The patients suffering from both types of diabetes were additionally subdivided according to the level of metabolic control and the duration of the disease. Xerostomia was diagnosed with the use of a specially prepared questionnaire and Fox's test. Moreover, the salivary flow rate of resting mixed saliva was measured. In type 1 diabetics, a significantly lower salivary flow rate in comparison to the age-matched control group (0.38 ± 0.19 mL/min vs. 0.53 ± 0.20 mL/min, p diabetics, a slight lower salivary flow rate was noticed (on average, 20% lower). Dry mouth was far more frequently diagnosed in type 1 diabetics than in the control group. In type 1 diabetics, in comparison to healthy subjects, a significantly lower resting flow rate of saliva and significantly higher prevalence of xerosomia were observed, but in type 2 diabetics, only a trend of such variability was observed.

  2. Food allergies in developing and emerging economies: need for comprehensive data on prevalence rates

    Full Text Available Abstract Although much is known today about the prevalence of food allergy in the developed world, there are serious knowledge gaps about the prevalence rates of food allergy in developing countries. Food allergy affects up to 6% of children and 4% of adults. Symptoms include urticaria, gastrointestinal distress, failure to thrive, anaphylaxis and even death. There are over 170 foods known to provoke allergic reactions. Of these, the most common foods responsible for inducing 90% of reported allergic reactions are peanuts, milk, eggs, wheat, nuts (e.g., hazelnuts, walnuts, almonds, cashews, pecans, etc., soybeans, fish, crustaceans and shellfish. Current assumptions are that prevalence rates are lower in developing countries and emerging economies such as China, Brazil and India which raises questions about potential health impacts should the assumptions not be supported by evidence. As the health and social burden of food allergy can be significant, national and international efforts focusing on food security, food safety, food quality and dietary diversity need to pay special attention to the role of food allergy in order to avoid marginalization of sub-populations in the community. More importantly, as the major food sources used in international food aid programs are frequently priority allergens (e.g., peanut, milk, eggs, soybean, fish, wheat, and due to the similarities between food allergy and some malnutrition symptoms, it will be increasingly important to understand and assess the interplay between food allergy and nutrition in order to protect and identify appropriate sources of foods for sensitized sub-populations especially in economically disadvantaged countries and communities.

    The purpose of this systematic review and meta-analysis was to provide a precise estimate of the period prevalence of needlestick injuries (NSI) among nurses working in hospitals in Iran and the reporting rate of NSI to nurse managers. We searched both international (PubMed, Scopus and the Institute for Scientific Information) and Iranian (Scientific Information Database, Iranmedex and Magiran) scientific databases to find studies published from 2000 to 2016 of NSI among Iranian nurses. The following keywords in Persian and English were used: "needle-stick" or "needle stick" or "needlestick," with and without "injury" or "injuries," "prevalence" or "frequency," "nurses" or "nursing staff," and "Iran." In a sample of 21 articles with 6,480 participants, we estimated that the overall 1-year period prevalence of NSI was 44% (95% confidence interval [CI], 35-53%) among Iranian nurses. The overall 1-year period prevalence of reporting NSI to nurse managers was 42% (95% CI, 33-52%). In meta-regression analysis, sample size, mean age, years of experience, and gender ratio were not associated with prevalence of NSI or reporting rate. The year of data collection was positively associated with period prevalence of NSI (p managers. Results indicated a high NSI period prevalence and low NSI reporting rate among nurses in Iran. Thus, effective interventions are required in hospitals in Iran to reduce the prevalence and increase the reporting rate of NSI. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    To explore effects of disease prevalence adjustment on ambulatory care-sensitive hospitalization (ACSH) rates used for quality comparisons. County-level hospital administrative data on adults discharged from German hospitals in 2011 and prevalence estimates based on administrative ambulatory diagnosis data were used. A retrospective cross-sectional study using in- and outpatient secondary data was performed. Hospitalization data for hypertension, diabetes, heart failure, chronic obstructive pulmonary disease, and asthma were obtained from the German Diagnosis Related Groups (DRG) database. Prevalence estimates were obtained from the German Central Research Institute of Ambulatory Health Care. Crude hospitalization rates varied substantially across counties (coefficients of variation [CV] 28-37 percent across conditions); this variation was reduced by prevalence adjustment (CV 21-28 percent). Prevalence explained 40-50 percent of the observed variation (r = 0.65-0.70) in ACSH rates for all conditions except asthma (r = 0.07). Between 30 percent and 38 percent of areas moved into or outside condition-specific control limits with prevalence adjustment. Unadjusted ACSH rates should be used with caution for high-stakes public reporting as differences in prevalence may have a marked impact. Prevalence adjustment should be considered in models analyzing ACSH. © Health Research and Educational Trust.

    Full Text Available Introduction: The adiponectin gene, ADIPOQ, encodes an adipocytokine, known as adiponectin hormone. This hormone is known to be associated with insulin sensitization, fat metabolism, immunity, and inflammatory response. Polymorphisms in ADIPOQ gene lower the adiponectin levels, increasing the risk for diabetes and cardiovascular diseases. Aims: The study aimed to calculate the prevalence rates of ADIPOQ polymorphisms in Indian population and to compare those prevalence rates with that of other populations. Subjects and Methods: Microarray-based genotypic data of 14 ADIPOQ polymorphisms from 703 individuals of Indian origin were used. Statistical Analysis Used: Frequency estimation, identity-by-descent, Hardy–Weinberg equilibrium, Chi-square test of significance were used for statistical analysis. Results: Allelic and genotypic frequencies of ADIPOQ polymorphisms, Chi-square tests of significance for allelic and genotypic frequencies across various populations. Conclusions: East Asians are very different from Indians in terms of allelic and genotypic frequencies of ADIPOQ polymorphisms. Europeans have similar genotypic and allelic patterns with Indians. Admixture Americans and Africans also showed significant differences with polymorphisms of the Indian population.

    This study aimed to report on the trends in incidence and prevalence rates of diabetes mellitus in Saudi Arabia over the last 25 years (1990-2015). A descriptive review. A systematic search was conducted for English-language, peer reviewed publications of any research design via Medline, EBSCO, PubMed and Scopus from 1990 to 2015. Of 106 articles retrieved, after removal of duplicates and quality appraisal, 8 studies were included in the review and synthesised based on study characteristics, design and findings. Studies originated from Saudi Arabia and applied a variety of research designs and tools to diagnosis diabetes. Of the 8 included studies; three reported type 1 diabetes and five on type 2 diabetes. Overall, findings indicated that the incidence and prevalence rate of diabetes is rising particularly among females, older children/adolescent and in urban areas. Further development are required to assess the health intervention, polices, guidelines, self-management programs in Saudi Arabia. Copyright © 2017. Published by Elsevier Ltd.

    Objective: To understand the prevalence rate and correlative factors of dislipidemia among Shanxi coal miners and to provide evidence for the development of programs on dislipidemia prevention. Methods: We investigated 1 337 mine workers from a Coal Group in April 2016 and collected data related to their blood biochemistry. We then classified the types in accordance with the diagnostic criteria of " Guidelines for prevention and treatment of dyslipidemia in Chinese adults (2007)" , using χ (2) test and unconditional logistic regression model for analysis. Results: The overall prevalence rate of Dislipidemia was 59.1% (790/1 337), with males as 60.4% (708/1 173) and females as 50.0%(82/164) while males appeared higher ( χ (2)=6.386, P dislipidemia ( χ (2)=7.117, P dislipidemia ( P dislipidemia. Conclusion: Among the coal mine workers, those who were males, aged from 20 to 34, having high blood pressure (systolic blood pressure abnormalities) or with high BMI (≥24.0 kg/m(2)) need to be taken special attention on care and prevention of dislipidemia.

    Objectives: The study aimed to assess the current epidemiology of hypertension, including its prevalence, the awareness of the condition and its treatment and control, in Turkey to evaluate changes in these factors over the last 10 years by comparing the results with the prevalence, awareness, treatment, and control of hypertension in Turkey (PatenT) study data (2003), as well as to assess parameters affecting awareness and the control of hypertension. Methods: The PatenT 2 study was conducted on a representative sample of the Turkish adult population (n = 5437) in 2012. Specifically trained staff performed the data collection. Hypertension was defined as mean SBP or DBP at least 140/90 mmHg, previously diagnosed disease or the use of antihypertensive medication. Awareness and treatment were assessed by self-reporting, and control was defined as SBP/DBP less than 140/90 mmHg. Results: Although the prevalence of hypertension in the PatenT and PatenT 2 surveys was stable at approximately 30%, hypertension awareness, treatment, and control rates have improved in Turkey. Overall, 54.7% of hypertensive patients were aware of their diagnosis in 2012 compared with 40.7% in 2003. The hypertension treatment rate increased from 31.1% in 2003 to 47.4% in 2012, and the control rate in hypertensives increased from 8.1% in 2003 to 28.7% in 2012. The rate of hypertension control in treated patients improved between 2003 (20.7%) and 2012 (53.9%). Awareness of hypertension was positively associated with older age, being a woman, residing in an urban area, a history of parental hypertension, being a nonsmoker, admittance by a physician, presence of diabetes mellitus, and being obese or overweight; it was inversely associated with a higher amount of daily bread consumption. Factors associated with better control of hypertension were younger age, female sex, residing in an urban area, and higher education level in Turkey. Conclusion: Although some progress has been made in

    To ascertain whether the tip-apex distance (TAD), calcar referenced TAD (CalTAD), and the sum of both (TADcalTAD) are predictive measurements of mobilisation of the cephalic screw in patients with trochanteric hip fractures. Between 2014 and 2015, 68 patients (mean age 86 years, 45 females, 23 males) with a trochanteric hip fracture underwent intramedullary nailing. The TAD and CalTAD were measured, and for each parameter, we calculated sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). There is evidence of a statistically significant association between a TAD and CalTAD greater than 25 mm and a TADcalTAD greater than 50 mm and mobilisation of the cephalic screw. All measurements have similar sensitivity, but the TAD presents the highest specificity (p TAD and CalTAD less than 25 mm and a TADcalTAD less than 50 mm when using intramedullary fixation.

    Full Text Available Background: Firefighters have a high probability of being exposed to a variety of traumatic events. Potentially traumatic events can occur during a single rescue such as: providing aid to seriously injured or helpless victims. Moreover, firefighters who are injured in the line of duty may have to retire as a consequence of their injury. The psychological cost of this exposure may increase the risk of long-term problems, such as post-traumatic stress disorder (PTSD symptoms, depression, and anxiety. Objective: The purpose of this study was to investigate the prevalence of PTSD symptoms, depression, anxiety, and assess related variables such as coping strategies and social support among Saudi firefighters. Method: Two hundred firefighters completed the Fire-fighter Trauma History Screen (FTHS to measure the number of traumatic events, Screen for Post-traumatic Stress Symptoms (SPTSS scale to assess the prevalence of PTSD symptoms, Hospital Anxiety and Depression Scales (HADS to assess depression and anxiety, Brief Cope (BC scale to measure coping strategies used, and Social Support scale was used to evaluate the firefighter's support received. Results: The results showed that 84% (169/200 of firefighters were exposed to at least one traumatic event. The result presented that 57% (96/169 of exposure firefighters fully met the DSM-IV criteria for PTSD with high levels of depression and anxiety; 39% (66/169 partially met the PTSD criteria. However, only 4% participants have not met the PTSD criteria. The results also revealed that adaptive coping strategies and higher perceived social support was associated with lower levels of PTSD. Conclusion: The high prevalence rate of PTSD related to the type and severity of the traumatic events and years of experience in the job. Accordingly, many firefighters were severely affected by their experiences, and we should be developing methods to help them.

    Full Text Available BACKGROUND: It is known that height and body mass index (BMI are correlated in childhood. However, its impact on the (trend of national prevalence rates of overweight and obesity has never been investigated. The aim of our study is to investigate the relation between height and national prevalence rates of overweight and obesity in childhood between 1980, 1997, and 2009, and to calculate which fixed value of p (2.0,2.1, …,3.0 in kg/m(p during childhood is most accurate in predicting adult overweight. METHODS AND FINDINGS: Cross-sectional growth data of children from three Dutch nationwide surveys in 1980, 1997, and 2009, and longitudinal data from the Terneuzen Birth Cohort and the Harpenden Growth Study were used. Relative risks (RR and 95% confidence intervals (CI were calculated. Our study showed that tall (>1 standard deviation (SD girls aged 5.0-13.9 y were more often overweight (RR = 3.5,95%CI:2.8-4.4 and obese (RR = 3.9,95%CI:2.1-7.4 than short girls (<-1 SD. Similar results were found in boys aged 5.0-14.9 y (RR = 4.4,95%CI:3.4-5.7 and RR = 5.3,95%CI:2.6-11.0. No large differences were found in the other age groups and in comparison with children with an average stature. Tall boys aged 2.0-4.9 y had a significantly higher positive trend in overweight between 1980 and 1997 compared to short boys (RR = 4.0,95%CI:1.38-11.9. For other age groups and in girls, no significant trends were found. The optimal Area Under the Curve (AUC to predict adult overweight was found for p = 2.0. CONCLUSIONS AND SIGNIFICANCE: Tall girls aged 5.0-13.9y and tall boys aged 5.0-14.9y have much higher prevalence rates of overweight and obesity than their shorter peers. We suggest taking into account the impact of height when evaluating trends and variations of BMI distributions in childhood, and to use BMI to predict adult overweight.

    Recent cases of bovine brucellosis (Brucella abortus) in cattle (Bos taurus) and domestic bison (Bison bison) of the southern Greater Yellowstone Area (SGYA) have been traced back to free-ranging elk (Cervus elaphus). Several management activities have been implemented to reduce brucellosis seroprevalence in elk, including test-and-slaughter, low-density feeding at elk winter feedgrounds, and elk vaccination. It is unclear which of these activities are most cost-effective at reducing the risk of elk transmitting brucellosis to cattle. In a companion paper, a stochastic risk model was used to translate a reduction in elk seroprevalence to a reduction in the risk of transmission to cattle. Here, we use those results to estimate the expected economic benefits and costs of reducing seroprevalence in elk using three different management activities: vaccination of elk with Brucella strain 19 (S19), low-density feeding of elk, and elk test-and-slaughter. Results indicate that the three elk management activities yield negative expected net benefits, ranging from -$2983 per year for low-density feeding to -$595,471 per year for test-and-slaughter. Society's risk preferences will determine whether strategies that generate small negative net benefit, such as low-density feeding, are worth implementing. However, activities with large negative net benefits, such as test-and-slaughter and S19 vaccination, are unlikely to be economically worthwhile. Given uncertainty about various model parameters, we identify some circumstances in which individual management activities might generate positive expected net benefit. Copyright © 2016 Elsevier B.V.

    The validity of diagnostic psychiatric instruments for depression and anxiety disorders may be compromised among patients with complex physical illness and disability. The objective of this study was to determine the effect on the prevalence rate of depression and anxiety in a nursing home population of attributing somatic symptoms of depression and anxiety to either somatic or psychiatric disorder. Symptoms of major depression (MD), generalized anxiety disorder (GAD) and panic disorder (PD) were measured using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN). Somatic symptoms of MD, GAD and PD were attributed to somatic causes when the interviewer was not sure about a psychiatric cause. To analyse the effect of this attribution on the prevalence rate of MD, GAD and PD, a sensitivity analysis was undertaken in which symptoms that were attributed to somatic causes were recoded as symptoms attributed to psychiatric disorder. Prevalence rates of MD, GAD and PD were calculated before and after recoding. The prevalence of MD after recoding rose from 7.5% to 8.1%. The prevalence of GAD did not change. The prevalence of PD rose from 1.5% to 1.8%. Attribution of somatic symptoms to either somatic or psychiatric disorder when the interviewer was not sure about a psychiatric cause of the somatic symptoms had only a very modest effect on the prevalence rate of major depression, generalized anxiety disorder and panic disorder in a nursing home population.

    The Azienda Sanitaria Locale Roma E (ASL-RME) outpatient clinic is the main reference center in Rome for HIV testing of foreign people. To define the prevalence and incidence of HIV infection among foreign transsexual sex workers attending the center. A cross-sectional, follow-up study was conducted. Between 1993 and 1999, 353 transsexuals attended the ASL-RME. They were from Colombia (n = 208), Brazil (n = 122), and other countries (n = 23). Most of these transsexuals reported having 5 to 10 partners per day. The overall HIV prevalence was 38.2%, which multivariate analysis found to be associated with origin from Brazil and a higher number of sex partners. The observed HIV seroconversion rate was 4.1 per 100 person-years, and non-regular condom use was the only factor related to seroconversion. The data from this study suggest that promotion of safer sex practices and regular condom use still is the main priority among marginalized population subgroups, such as foreign prostitutes, involved in sex activities that put them at risk for HIV infection.

    The rapid socioeconomic transition in post-communist Hungary adversely affected the overall morbidity and mortality rates in the 1990s. Prevalence data on depressive disorders from the region are still scarce, however. This study reports the findings of the first epidemiological survey, using the Edinburgh Postnatal Depression Scale (EPDS) and the Beck Depression Inventory (BDI), on the prevalence of post-partum depression and the associated risk factors in Hungary. A total of 1030 mothers who delivered their babies between May and July 1999 in 16 counties in Hungary were screened for depressive symptoms 3-26 weeks post-partum. The survey found that 10.81% of the sample was above the cut-off score of 13, and the EPDS detected post-partum depressive symptoms with 76% (95% confidence interval (CI)=60.5-87.1) sensitivity and 92% (95% CI=90.5-94.1) specificity. In addition, 24 socio-demographic, socio-psychiatric data and personal and obstetric variables were surveyed. Results of a hierarchical logistic regression analysis showed that depression of the mother during pregnancy was the strongest predictor of depressive symptoms post-partum. Depression before pregnancy, housing conditions, marital relationship status and family history of alcohol problems were also identified as predictors for post-partum depressive symptoms.

    Children with disabilities have been shown to be at greater risk of victimization than those without. Although much of the research combines disability of any type into a single disability category, recent evidence suggests that not all types of disabilities are equally associated with victimization. To date, little knowledge exists about the victimization of youth with physical disabilities. This study used data from a national school-based survey of adolescents (n = 6,749, mean age = 15.41, SD = .66) in Switzerland to investigate sexual victimization (SV) among physically disabled youth. Two subtypes of SV were differentiated: contact SV, including penetration or touching/kissing, and non-contact SV, such as exhibitionism, verbal harassment, exposure to sexual acts, or cyber SV. A total of 360 (5.1%) youth self-identified as having a physical disability. Lifetime prevalence rates for contact SV were 25.95% for girls with a physical disability (odds ratio [OR] = 1.29 compared with able-bodied girls), 18.50% for boys with physical disability (OR = 2.78 compared with able-bodied boys), and 22.35% for the total sample with physical disability (OR = 1.74 compared with able-bodied youth). For non-contact SV, the lifetime prevalence was 48.11% for girls with a physical disability (OR = 1.44 compared with able-bodied girls), 31.76% for boys with physical disability (OR = 1.95 compared with able-bodied boys), and 40.28% for the total sample with physical disability (OR = 1.67 compared with able-bodied youth). After controlling for other risk factors, physical disability was a significant predictor of contact and non-contact SV for boys, but not for girls. © The Author(s) 2014.

    Full Text Available The aim of this study was to assess the prevalence of sinus-lifting procedures and survival rates of implants placed in the posterior maxilla. This retrospective chart review examined consecutive patients with tooth/teeth loss in the posterior maxilla between 2008 and 2012 treated with sinus lift, when needed, and implant insertion. Demographic variables, health status, residual alveolar bone height, augmentation types, the implant position, diameter and height, and implant failure, prosthesis types, and the marginal bone loss were recorded. The study included 302 patients at a mean age of 5.2 years, who received a total of 609 dental implants. A total of 380 (62.3% implants were inserted in native areas, 203 (33.3% ones in external sinus-lifted areas and 26 (4.4% ones in internal lifted areas. The survival rate in native or internal lifted areas were 100% and 95.6% in external sinus lifted ones (10 implant failures/203 implants. Almost half of the implants were examined radiologically with a mean duration of 30 months and the mean marginal bone loss was 0.64 ± 1.2 mm. The results showed that the survival rates of native bone and the internal sinus lifting were slightly higher than that of external sinus lifting. Implants placed with sinus augmentation exhibited more marginal bone loss than implants in native bone.

    Background Acute transfusion reactions are probably common in sub-Saharan Africa, but transfusion reaction surveillance systems have not been widely established. In 2008, the Blood Transfusion Service of Namibia implemented a national acute transfusion reaction surveillance system, but substantial under-reporting was suspected. We estimated the actual prevalence and rate of acute transfusion reactions occurring in Windhoek, Namibia. Methods The percentage of transfusion events resulting in a reported acute transfusion reaction was calculated. Actual percentage and rates of acute transfusion reactions per 1,000 transfused units were estimated by reviewing patients’ records from six hospitals, which transfuse >99% of all blood in Windhoek. Patients’ records for 1,162 transfusion events occurring between 1st January – 31st December 2011 were randomly selected. Clinical and demographic information were abstracted and Centers for Disease Control and Prevention National Healthcare Safety Network criteria were applied to categorize acute transfusion reactions1. Results From January 1 – December 31, 2011, there were 3,697 transfusion events (involving 10,338 blood units) in the selected hospitals. Eight (0.2%) acute transfusion reactions were reported to the surveillance system. Of the 1,162 transfusion events selected, medical records for 785 transfusion events were analysed, and 28 acute transfusion reactions were detected, of which only one had also been reported to the surveillance system. An estimated 3.4% (95% confidence interval [CI]: 2.3–4.4) of transfusion events in Windhoek resulted in an acute transfusion reaction, with an estimated rate of 11.5 (95% CI: 7.6–14.5) acute transfusion reactions per 1,000 transfused units. Conclusion The estimated actual rate of acute transfusion reactions is higher than the rate reported to the national haemovigilance system. Improved surveillance and interventions to reduce transfusion-related morbidity and mortality

    Pressure ulcer prevalence rates provide useful information about the magnitude of this health problem. Only limited information on pressure ulcers in Germany was available before 2001. The purpose of this study was to compare results of seven pressure ulcer prevalence surveys which were conducted annually between 2001 and 2007 and to explore whether pressure ulcer prevalence rates decreased. The second aim was to evaluate if the measured prevalence rates of our sample could be generalised for all German hospitals. Results of seven point pressure ulcer prevalence studies conducted in 225 German hospitals were analysed. Chi-square tests, chi-square trend tests and one-way ANOVA to assess differences and trends across the years were applied. The sample was stratified according to pressure ulcer risk and speciality. Finally, study samples were compared with the potential population. In total data of 40,247 hospital patients were analysed. The overall pressure ulcer prevalence rate in German hospitals was 10.2%. Patient samples of each year were comparable regarding gender, age and pressure ulcer risk. Pressure ulcer prevalence rates decreased from 13.9% (year 2001) to 7.3% (year 2007) (pcare units remained stable. With some limitations our study results are representative for all hospitals within Germany. It is highly probable that the decrease of prevalence rates was due to an increased awareness of the pressure ulcer problem in Germany and subsequent efforts to improve pressure ulcer prevention and treatment. The quality of clinical practice regarding pressure ulcer prevention and treatment has improved. However, pressure ulcers are still relevant and require attention. In 2007, one out of 10 hospital patients who were at pressure ulcer risk had at least one pressure related skin damage.

    Full Text Available It is known that overworking as well as deficiency of work (plenty of free time are major factors of a suicide on an individual level which allows when passing to the level of a real social group (employees to suppose of existence of a certain optimum of working time or a parabolic (U-shaped connection between the suicide rate and an average duration of working time. From the theoretical point of view the supposed parabolic dependence of the level of prevalence of suicides from an average duration of working time of employees is described from the point of view of suicidology: excessive increase of working time is an external tendency which prevents satisfaction of actual needs of an employee and limits physically the space (off-work time for their realization. Multidirectional tendencies form a life conflict which has crucial significance when transferring to a suicidal phase. The objective of this article consists in a qualitative assessment of an influence of “an average duration of working time” on the level of prevalence of suicides when other things are fixed (economic, social, religious and others in a relatively stable social situation. For the econometric analysis, reliable and comparable data of the European database of detailed mortality data of the World Health Organization and Eurostat are used for 22 European countries for the period from 1998 till 2012. Based on analysis of a dynamics of the studied variables different hypothesis have been made: 1 about existence of statistically significant linear or logarithmic dependence of the level of prevalence of suicides from an average factual duration of working time inside a country 2 about existence of a parabolic (U-shaped dependence of the level of prevalence of suicides from an average factual duration of working time between countries.

    Full Text Available Abstract Background Hypertension is a global health issue and is currently increasing at rapid pace in South Asian countries including Bangladesh. Although, some studies on hypertension have been conducted in Bangladesh, there is a lack of scientific evidence in the adult student population that was missing from the previous and recent national cross-sectional studies. Moreover, the specific risk factors of hypertension in the Bangladeshi adults still need to be investigated. This study was conducted to estimate hypertension prevalence among adult students in Bangladesh and to test the hypothesis of Luke et al. (Hypertension 43:555–560, 2004 that basal metabolic rate (BMR and blood pressure are positively associated independent of body size. Method The data was collected on 184 adult university students (118 female and 66 male in Dhaka, Bangladesh. Anthropometric, BMR details and an average of at least two blood pressure measurements were obtained. Hypertension was defined by a systolic blood pressure (SBP ≥ 140 mmHg and/or, diastolic blood pressure (DBP ≥ 90 mmHg. Results Overall, 6.5% of participants had hypertension with significantly (p < 0.001 higher prevalence in male (12.1% than in the female (3.4% students. Age and BMI showed positive and significant correlation with hypertension among the students. When adjusted for body mass index (BMI, as well as other potentially confounding variables such as age, sex, smoking status and degree of urbanization, BMR was positively correlated with SBP and DBP (p < 0.001. Thus, higher BMR is associated with SBP and DBP; this is opposite the well documented inverse relationship between physical activity and blood pressure. If the influence of BMR on blood pressure is confirmed, the systematically elevated BMR might be an important predictor that can explain relatively high blood pressure and hypertension in humans. Conclusion This study reports the prevalence and associated risk factors

When adjusted for body mass index (BMI), as well as other potentially confounding variables such as age, sex, smoking status and degree of urbanization, BMR was positively correlated with SBP and DBP (p < 0.001). Thus, higher BMR is associated with SBP and DBP; this is opposite the well documented inverse relationship between physical activity and blood pressure. If the influence of BMR on blood pressure is confirmed, the systematically elevated BMR might be an important predictor that can explain relatively high blood pressure and hypertension in humans. This study reports the prevalence and associated risk factors of hypertension in the Bangladeshi adult students. The

    Monitoring overweight in risk groups is necessary. Our aim is to assess the trend in overweight and obesity in Turkish and Moroccan children in the Netherlands since 1997 and to monitor the levels of lifestyle-related behaviours in 2009. We selected cross-sectional data of Turkish and Moroccan children aged 2-18 years from two national Growth Studies performed in 1997 and 2009 in the Netherlands. Lifestyle-related behaviours were obtained in the 2009 study by questionnaire. In 2009, 31.9% of Turkish and 26.6% of Moroccan children had overweight, whereas this was, respectively, 26.7% and 19.6% in 1997. Already at 2 years, 21.1% in Turkish and 22.7% in Moroccan children had overweight in 2009. The prevalence of obesity was above 4% from 3 years onwards. High (i.e. ≥ 25%) prevalence rates of unhealthy lifestyle-related behaviours were found for not having breakfast (26-49%) among Turkish and Moroccan adolescent (i.e. 15-18 years) girls, consuming no fruit (29-45%) and watching TV/PC ≥ 2 h (35-72%) among all Turkish and Moroccan adolescents, no walking/cycling to school/day care among preschool children (2-4 years) (28-56%) and adolescents (34-94%), drinking ≥ 2 glasses of sweet beverages (44-74%) and being children. An upward trend of overweight and obesity occurred in Turkish and Moroccan children. Already at 2 years of age, one out of five Turkish and Moroccan children had overweight, which calls for early prevention with attention to specific lifestyle-related behaviours. © The Author 2015.

    Prevalence rates are still lacking for posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) diagnoses based on the new ICD-11 criteria. In a nationwide representative German sample (N = 2524; 14-99 years), exposure to traumatic events and symptoms of PTSD or CPTSD were assessed with the International Trauma Questionnaire. A clinical variant of CPTSD with a lower threshold for core PTSD symptoms was also calculated, in addition to conditional prevalence rates dependent on trauma type and differential predictors. One-month prevalence rates were as follows: PTSD, 1.5%; CPTSD, 0.5%; and CPTSD variant, 0.7%. For PTSD, the highest conditional prevalence was associated with kidnapping or rape, and the highest CPTSD rates were associated with sexual childhood abuse or rape. PTSD and CPTSD were best differentiated by sexual violence. Combined PTSD and CPTSD (ICD-11) rates were in the range of previously reported prevalences for unified PTSD (Diagnostic and Statistical Manual of Mental Disorders, 4th Edition; ICD-10). Evidence on differential predictors of PTSD and CPTSD is still preliminary.

    Over the past three decades, undernutrition in Thailand has drastically reduced by over seven times. However, since 1995 the number of patients afflicted with non-communicable diseases, such as diabetes mellitus, has rapidly increased, even among the young. Unhealthy life styles due to urbanization are a major reason for this increase. Less physical activity and low consumption of fruits and vegetables, as well as high consumption of added free sugar, are common. Every year, the Thai people increase their consumption of energy from fat and protein, while lowering their intake of energy from complex carbohydrates. Per capita and on average, a Thai individual consumes up to 20% of total energy from added free sugar. Barker's hypothesis and Developmental Origins of Health and Disease hypothesis (DOHaD) can partially explain the increase in diabetes mellitus at this rapid rate. To alleviate the problem, the main strategy has been consumer education to reduce diabetes mellitus prevalence. Sugar elimination from infant formula is mandatory and sugar taxation is being considered. Simplified nutrition labeling is voluntarily as part of consumer education, as well as encouraging food industries to produce healthier food products. Currently, a multi-sectoral approach is used for alleviating diabetes mellitus in Thailand.

    The aim of the present study was to determine the prevalence and reporting rate of incidental findings (IF) in adult outpatients undergoing lumbar magnetic resonance imaging (MRI). Re-evaluation of a total of 1278 lumbar MRI images (collected from patients with a mean age of 50.5 years, range 16-91 years) captured between August 2010-August 2011 was done by a neuroradiologist and a musculoskeletal radiologist. IFs were classified according to organ or system (liver, gallbladder, kidney, bladder, uterus, ovary, lymph node, intestine and aorta). The rate of reporting of a range of IF was examined. The outcome of each patient's treatment was evaluated based on review of hospital records and by telephone interviews. A total of 253 IFs were found in 241 patients (18.8% of 1278). Among these, clinically significant IFs (n = 34) included: 2 renal masses (0.15%), 2 aortic aneurysms (0.15%), 2 cases of hydronephrosis (0.15%), 11 adrenal masses (0.86%), 7 lymphadenopathies (0.55%), 6 cases of endometrial or cervical thickening (0.47%), 1 liver hemangioma (0.08%), 1 pelvic fluid (0.08%) and 2 ovarian dermoid cysts (0.15%). Overall, 28% (71/253) of IFs were included in the clinical reports, while clinically significant findings were reported in 41% (14/34) of cases. Extraspinal IFs are commonly detected during a routine lumbar MRI, and many of these findings are not clinically significant. However, IFs including clinically important findings are occasionally omitted from formal radiological reports.

    Full Text Available Abstract Background Neonatal infection constitutes one of Senegal’s most important public health problems, with a mortality rate of 41 deaths per 1,000 live births. Methods Between January 2007 and March 2008, 242 neonates with suspected infection were recruited at three neonatal intensive care units in three major tertiary care centers in Dakar, the capital of Senegal. Neonatal infections were confirmed by positive bacterial blood or cerebrospinal fluid culture. The microbiological pattern of neonatal infections and the antibiotic susceptibility of the isolates were characterized. In addition, the genetic basis for antibiotic resistance and the genetic background of third-generation cephalosporin-resistant (3GC-R Enterobacteriaceae were studied. Results A bacteriological infection was confirmed in 36.4 % (88/242 of neonates: 22.7 % (30/132 during the early-onset and 52.7 % (58/110 during the late-onset periods (p > 0.20. Group B streptococci accounted for 6.8 % of the 88 collected bacterial isolates, while most of them were Enterobacteriaceae (n = 69, 78.4 %. Of these, 55/69 (79.7 % were 3GC-R. The blaCTX-M-15 allele, the blaSHV and the blaTEM were highly prevalent (63.5, 65.4 and 53.8 %, respectively, usually associated with qnr genes (65.4 %. Clonally related strains of 3GC-R Klebsiella pneumoniae and 3GC-R Enterobacter cloacae, the two most commonly recovered 3GC-R Enterobacteriaceae (48/55, were detected at the three hospitals, underlining the role of cross-transmission in their spread. The overall case fatality rate was 18.6 %. Conclusions Measures should be taken to prevent nosocomial infections and the selection of resistant bacteria.

    Growth faults are common and continue to evolve throughout the unconsolidated sediments of Greater Houston (GH) region in Texas. Presence of faults can induce localized surface displacements, aggravate localized subsidence, and discontinue the integrity of ground water flow. Property damages due to fault creep have become more evident during the past few years over the GH area, portraying the necessity of further study of these faults. Interferometric synthetic aperture radar (InSAR) has been proven to be effective in mapping creep along and/or across faults. However, extracting a short wavelength, as well as small amplitude of the creep signal (about 10-20 mm/year) from long time span interferograms is extremely difficult, especially in agricultural or vegetated areas. This paper aims to map and monitor the latest rate, extent, and temporal evolution of faulting at a highest spatial density over GH region using an improved Multi-temporal InSAR (MTI) technique. The method, with maximized usable signal and correlation, has the ability to identify and monitor the active faults to provide an accurate and elaborate image of the faults. In this study, two neighboring ALOS tracks and Sentinel-1A datasets are used. Many zones of steep phase gradients and/or discontinuities have been recognized from the long term velocity maps by both ALOS (2007-2011) and Sentinei-1A (2015-2017) imagery. Not only those previously known faults position but also the new fault traces that have not been mapped by other techniques are imaged by our MTI technique. Fault damage and visible cracking of ground were evident at most locations through our field survey. The discovery of new fault activation, or faults moved from earlier locations is a part of the Big Barn Fault and Conroe fault system, trending from southwest to northeast between Hockley and Conroe. The location of area of subsidence over GH is also shrinking and migrating toward the northeast (Montgomery County) after 2000. The

    The validated hypoallergenic (vh) rating system was initiated in 1988 to try to objectively validate the "hypoallergenic" claim in cosmetics. To show how the system rates cosmetic hypoallergenicity and to compare the prevalence of cosmetic contact dermatitis (CCD) among users of regular cosmetics versus cosmetics with high VH numbers. (1) Made a VH list based on top allergens from patch-test results published by the North American Contact Dermatitis Group (NACDG) and the European Surveillance System on Contact Allergies (ESSCA); (2) reviewed global regulatory, cosmetic, drug, packaging, and manufacturing practices to show how allergens may contaminate products; (3) compared cosmetic ingredients lists against the VH list to obtain the VH rating (the more allergens absent, the higher the VH rating); and (4) obtained CCD prevalence among users of regular cosmetics versus users of cosmetics with high VH ratings. (1) Two VH lists (1988, 2003) included only cosmetic allergens in the NACDG surveys, the third (2007) included cosmetic and potential contaminant noncosmetic allergens, and the fourth (2010) adds ESSCA patch-test surveys. (2) CCD prevalence is 0.05 to 0.12% (average, 0.08%) among users of cosmetics with high VH ratings versus 2.4 to 36.3% among users of regular cosmetics. The VH rating system is shown to objectively validate the hypoallergenic cosmetics claim.

    During the administration of intra-arterial (IA) chemotherapy for the treatment of brain tumors (BTs), angiography may demonstrate asymptomatic, incidental cerebral aneurysms. The prevalence and complication rate of incidental aneurysms in patients undergoing IA chemotherapy remains unknown. It remains unclear whether the presence of an aneurysm represents an increased risk or a contraindication to this form of treatment. We performed a chart and angiography review of BT patients receiving IA chemotherapy over the previous 16 months. Seventy-eight patients were identified with primary (39) and metastatic (39) BTs. The cohort consisted of 40 men and 38 women, with a mean age of 47.8 years (range, 22-80 years). During initial angiography, 8 patients (10.3%) were identified with incidental cerebral aneurysms. The aneurysms were saccular and varied in size from 2-4 mm (mean, 3 mm). Seven of the 8 patients continued IA chemotherapy after detection of the aneurysm, for a total of 35 IA procedures. Of these 7 patients, 5 expired from nonaneurysmal complications (mean survival, 5.4 months; range, 2-10 months); 4 from the primary tumor, and one from an infected craniotomy site. Two patients continue to survive; one remains in treatment, and the other has completed 12 months of IA therapy. There were no aneurysmal complications during or after IA treatment in any of the BT patients. Incidental aneurysms may be more common in patients with BTs than the general population. In our patient population, there was no indication that an incidental aneurysm was reason to preclude or delay the use of IA chemotherapy.

    Highlights: • Various thoracic CT findings, including cysts, mediastinal masses, etc. were found. • Cysts show upper and peripheral dominant distribution. • The number, size, and distribution of the pulmonary cysts in NF-1 revealed significant correlation. • It is suspected that thoracic CT findings in NF-1 occur independently. - Abstract: Purpose: To evaluate the prevalence rates and the correlations of thoracic computed tomography (CT) findings of neurofibromatosis 1 (NF1) in 88 patients. Materials and methods: Chest CT images of 88 NF1 patients were independently reviewed by three observers, and the CT findings were evaluated. If abnormal findings were present, their number, size, and distribution were recorded. The prevalence rate of each CT finding was calculated, and the correlations between CT findings were analyzed. Results: Of the 88 cases, 13 were positive for cysts, 16 for emphysema, 8 for nodules, 8 for GGNs (ground glass nodules), 13 for mediastinal masses, 20 for scoliosis, 44 for subcutaneous nodules, and 34 for skin nodules. Cysts showed upper and peripheral dominant distributions. Regarding 13 mediastinal masses, 2 were diagnosed as malignant peripheral nerve sheath tumors (MPNSTs), 1 was diagnosed as primary lung cancer, 2 were diagnosed as lateral meningocele, 3 were diagnosed as neurofibromas, and the remaining 7 were considered neurofibromas. There was a significant correlation between the prevalence of subcutaneous nodules and that of skin nodules. Significant positive correlations were also seen between size and number, size and rate of central distribution, and number and rate of central distribution of cysts. Conclusion: Various CT findings were found in NF-1 patients, and the prevalence rates of subcutaneous and skin nodules were higher than other findings. Though the prevalence rates of subcutaneous nodules and skin nodules were significantly correlated, the other CT findings in NF-1 occurred independently. The number, size, and

    The prevalence of school students at risk of anaphylaxis in Victoria is unknown and has not been previously studied. Similarly, rates of adrenaline autoinjector usage in the school environment have yet to be determined given increasing prescription rates. We sought to determine time trends in prevalence of school children at risk of anaphylaxis across all year levels and the annual usage rate of adrenaline autoinjectors in the school setting relative to the number of students at risk of anaphylaxis. Statewide surveys from more than 1,500 government schools including more than 550,000 students were used and prevalence rates (%) with 95% CIs were calculated. The overall prevalence of students at risk of anaphylaxis has increased 41% from 0.98% (95% CI, 0.95-1.01) in 2009 to 1.38% (95% CI, 1.35-1.41) in 2014. There was a significant drop in reporting of anaphylaxis risk with transition from the final year of primary school to the first year of secondary school, suggesting a change in parental reporting of anaphylaxis risk among secondary school students. The number of adrenaline autoinjectors activated per 1000 students at risk of anaphylaxis ranged from 6 to 8 per year, with consistently higher activation use in secondary school students than in primary school students. Statewide prevalence of anaphylaxis risk has increased in children attending Victorian government schools. However, adrenaline autoinjector activation has remained fairly stable despite known increase in the rates of prescription. Copyright © 2016 American Academy of Allergy, Asthma & Immunology.

    Full Text Available Background. We investigated the association between the reduction in the estimated glomerular filtration rate (eGFR and the prevalence of monoclonal gammopathy of undetermined significance (MGUS in Korean males. Methods. We enrolled 723 healthy Korean males. Serum creatinine concentration, serum electrophoresis, serum immunofixation, and the serum free light chain assay were performed. We calculated delta eGFR per year (ΔeGFR/yr. The prevalence of MGUS was compared based on the ΔeGFR/yr and age group. Results. Thirteen (1.8% of 723 participants exhibited the monoclonal band on serum immunofixation. Prevalence of MGUS by age group was 0.00% (0/172 for 40 years, 1.63% (6/367 for 60 years, and 3.80% (7/184 for >60 years. The median decrease in ΔeGFR/yr was 5.3%. The prevalence of MGUS in participants in their 50s with >5.3% decline in ΔeGFR/yr was significantly higher than those with 5.3% decrease in ΔeGFR/yr was similar to that of healthy males in their 60s. Conclusion. Using the rate of reduction in ΔeGFR/yr in healthy Korean males who had their serum creatinine level checked regularly may increase the MGUS detection rate in clinical practice.

    Animals modulate the power output needed for different locomotor tasks by changing muscle forces and fascicle strain rates. To generate the necessary forces, appropriate motor units must be recruited. Faster motor units have faster activation-deactivation rates than slower motor units, and they contract at higher strain rates; therefore, recruitment of faster motor units may be advantageous for tasks that involve rapid movements or high rates of work. This study identified motor unit recruitment patterns in the gastrocnemii muscles of goats and examined whether faster motor units are recruited when locomotor speed is increased. The study also examined whether locomotor tasks that elicit faster (or slower) motor units are associated with increased (or decreased) in vivo tendon forces, force rise and relaxation rates, fascicle strains and/or strain rates. Electromyography (EMG), sonomicrometry and muscle-tendon force data were collected from the lateral and medial gastrocnemius muscles of goats during level walking, trotting and galloping and during inclined walking and trotting. EMG signals were analyzed using wavelet and principal component analyses to quantify changes in the EMG frequency spectra across the different locomotor conditions. Fascicle strain and strain rate were calculated from the sonomicrometric data, and force rise and relaxation rates were determined from the tendon force data. The results of this study showed that faster motor units were recruited as goats increased their locomotor speeds from level walking to galloping. Slow inclined walking elicited EMG intensities similar to those of fast level galloping but different EMG frequency spectra, indicating that recruitment of the different motor unit types depended, in part, on characteristics of the task. For the locomotor tasks and muscles analyzed here, recruitment patterns were generally associated with in vivo fascicle strain rates, EMG intensity and tendon force. Together, these data provide

    Objective: To analyze the rate of prevalence, awareness, treatment and control of hypertension among women at reproductive age (18-49 years old) in China in 2013. Methods: The analysis used data obtained from the China Chronic and non-communicable disease surveillance in 2013.The surveillance included 176 534 adults aging ≥18 years old, who were selected from 302 surveillance points by multi-stage cluster random sampling method. A total of 46 674 women at reproductive age (18-49 years old) were investigated. Blood pressures were measured by electronic blood pressure monitor. After being weighted according to complex sampling scheme and post-stratification, the rate of prevalence, awareness, treatment and control of hypertension were compared by different characteristics such as age, education, urban and rural areas, and geographic locations. Results: The prevalence of hypertension among women at reproductive age (18-49 years old) in China in 2013 was 13.5%. The rate in the rural areas was higher than that in urban areas (χ(2)=46.23, P 0.05). The hypertension prevalence in all age groups (18-24, 25-29, 30-34, 35-39, 40-44, 45-49 years old) were 6.6%, 9.2%, 9.6%, 12.0%, 17.9% and 28.3%, respectively. The prevalence of hypertension showed a rising trend with age increasing ( t= 12.32, Pareas; and 21.3%, 18.5% and 5.9%, respectively in rural areas. The rates in urban areas were all higher than those in rural areas (chi square were separately 18.98, 21.31, and 6.80, P values areas.

    A combined epidemiologic and malacologic survey of schistosomiasis in Puerto Rico was carried out in areas where previous surveys had reported the prevalence of the disease. This limited survey, with 495 persons examined, found a low prevalence (0.6%) of Schistosoma mansoni infections. The infections were restricted to three people more than 36 years of age. No infections were detected in children 16 years of age or less, and this cohort comprised 57.8% of the study group. Malacologic surveys of the four streams, 10 rivers, and eight lakes throughout the island revealed the absence of intermediate host Biomphalaria glabrata and the presence of Thiara granifera, a competitive species of B. glabrata and the predatory snail Marisa cornuarietis. We believe that the absence of B. glabrata is the primary reason for the sustained reduction in the prevalence of schistosomiasis in Puerto Rico.

    IMPORTANCE Sexual violence can emerge in adolescence, yet little is known about youth perpetrators-especially those not involved with the criminal justice system. OBJECTIVE To report national estimates of adolescent sexual violence perpetration and details of the perpetrator experience. DESIGN, SETTING, AND PARTICIPANTS Data were collected online in 2010 (wave 4) and 2011 (wave 5) in the national Growing Up With Media study. Participants included 1058 youths aged 14 to 21 years who at baseline read English, lived in the household at least 50% of the time, and had used the Internet in the last 6 months. Recruitment was balanced on youths' biological sex and age. MAIN OUTCOMES AND MEASURES Forced sexual contact, coercive sex, attempted rape, and completed rape. RESULTS Nearly 1 in 10 youths (9%) reported some type of sexual violence perpetration in their lifetime; 4% (10 females and 39 males) reported attempted or completed rape. Sixteen years old was the mode age of first sexual perpetration (n = 18 [40%]). Perpetrators reported greater exposure to violent X-rated content. Almost all perpetrators (98%) who reported age at first perpetration to be 15 years or younger were male, with similar but attenuated results among those who began at ages 16 or 17 years (90%). It is not until ages 18 or 19 years that males (52%) and females (48%) are relatively equally represented as perpetrators. Perhaps related to age at first perpetration, females were more likely to perpetrate against older victims, and males were more likely to perpetrate against younger victims. Youths who started perpetrating earlier were more likely than older youths to get in trouble with caregivers; youths starting older were more likely to indicate that no one found out about the perpetration. CONCLUSIONS AND RELEVANCE Sexual violence perpetration appears to emerge earlier for males than females, perhaps suggesting different developmental trajectories. Links between perpetration and violent sexual

    This study examined the effects of high- vs. moderate-intensity interval training on cardiovascular fitness, leptin levels and ratings of perceived exertion (RPE) in obese female adolescents. Forty-seven participants were randomly assigned to one of three groups receiving either a 1:1 ratio of 15 s of effort comprising moderate-intensity interval training (MIIT at 80% maximal aerobic speed: MAS) or high-intensity interval training (HIIT at 100% MAS), with matched 15 s recovery at 50% MAS, thrice weekly, or a no-training control group. The HIIT and MIIT groups showed improved (p HIIT group showed decreased waist circumference (WC) (p = 0.017). The effect of exercise on maximal oxygen uptake (VO2max) was significant (p = 0.019, ES = 0.48 and p = 0.010, ES = 0.57, HIIT and MIIT, respectively). The decrease of rate-pressure product (RPP) (p HIIT and MIIT, respectively) followed the positive changes in resting heart rate and blood pressures. Blood glucose, insulin level and the homeostasis model assessment index for insulin decreased (p HIIT and MIIT, respectively. In the post-intervention period, blood leptin was strongly associated with %BF (p HIIT and MIIT groups, respectively, while RPE was strongly associated with BM (p HIIT group. The results suggest that high-intensity interval training may produce more positive effects on health determinants in comparison with the same training mode at a moderate intensity.

    The purpose of this study was to assess if the presence of information including the pretest probability (Wells score), other known risk factors, and symptoms given on referrals for computed tomography (CT) pulmonary angiography correlated with prevalence rates for pulmonary embolism (PE). Also, to evaluate for differences between a university and a regional hospital setting regarding patient characteristics, amount of relevant information provided on referrals, and prevalence rates for pulmonary embolism. Retrospective review of all consecutive referrals (emergency room, inpatient, and outpatient) for CT performed on children and adults for suspected PE from two sites: a tertiary (university) hospital (site 1) and a secondary (regional) hospital (site 2) over a 5-year period. The overall prevalence rate was 510/3641 or 14% of all referrals. Significantly higher number of males had a positive CT compared to women (18% versus 12%, P relevant information on the referral and the probability for positive finding existed, a slight trend was noted (P = .09). In two categories, "hypoxia" and "signs of deep vein thrombosis," the presence of this information conferred a higher probability for pulmonary embolism, P information conferred a higher probability for pulmonary embolism. The amount of relevant clinical information on the request did not correlate with prevalence rates, which may reflect a lack of documentation on the part of emergency physicians who may use a "gestalt" approach. Request forms likely did not capture all relevant patient risks and many factors may interact with each other, both positively and negatively. Pretest probability estimations were rarely performed, despite their inclusion in major society guidelines. Copyright © 2013 AUR. Published by Elsevier Inc. All rights reserved.

    The Do value fibroblastoid colony-forming units in mouse bone-marrow increased from 1.7 Gy using γ-rays at 4.2 Gy/minute, to 2.6 Gy at 4.5 cGy/minute. In contrast, the sensitivity of bone-marrow stem cells was very little changed (Do approximately 0.9 Gy). At 7.5 Gy acute single dose, the dose sparing achieved for CFU-F using 4.5 cGy/minute was a factor of 1.4, inbetween the values reported for lung of 1.8 and for haemopoiesis of 1.2. Although the role of CFU-F in the haemopoietic environment has not been established, the content of CFU-F can predict the ability of irradiated marrow to sustain haemopoiesis in the long term. Hence the data imply that the haemopoiesis environment, as well as the dose-limiting lung, benefits from the use of low dose-rates for haemopoietic ablations in the treatment of leukaemia. No significant further sparing of CFU-F was achieved using a lower dose-rate of 1.4 cGy per minute

    The purpose of this investigation was to examine the relationship between impaired driving crashes and public beliefs and concerns about impaired driving across each of Maryland's twenty-four counties (including Baltimore City). It was hypothesized that residents of counties that experience higher impaired driving crashes would express more concerns about impaired driving and perceive more risks about driving impaired than residents of counties that have lower rates of impaired driving. Data for alcohol impaired driving crashes were obtained for the years 2004-2006. These data were compared to public opinion data that was obtained annually by random-digit-dial telephone surveys from 2004 to 2007. Concerns about drunk driving as well as perceptions of the likelihood of being stopped by the police if one were to drive after having too much to drink were related to counties with higher serious impaired driving crash rates, as were perceptions that the police and the legal system were too lenient. Perceptions about the likelihood of being stopped by the police were higher in those counties with more impaired driving enforcement activity. Perceptions of concern appear to be shaped more by crash exposure than enforcement activity. Campaigns that address impaired driving prevention should substantially increase enforcement, strengthen the adjudication process of impaired drivers, and emphasize the potential seriousness of drinking-driving crashes in their promotional activities.

    The purpose of the current study was to explore if training regimes utilizing diverse training intensity distributions result in different responses on neuromuscular status, anaerobic capacity/power and acute heart rate recovery (HRR) in well-trained endurance athletes. Methods: Thirty-six male (n = 33) and female (n = 3) runners, cyclists, triathletes and cross-country skiers [peak oxygen uptake: (VO2peak): 61.9 ± 8.0 mL·kg−1·min−1] were randomly assigned to one of three groups (blocked high intensity interval training HIIT; polarized training POL; high volume low intensity oriented control group CG/HVLIT applying no HIIT). A maximal anaerobic running/cycling test (MART/MACT) was performed prior to and following a 9-week training period. Results: Only the HIIT group achieved improvements in peak power/velocity (+6.4%, P 0.05). Acute HRR was improved in HIIT (11.2%, P = 0.002) and POL (7.9%, P = 0.023) with no change in the HVLIT oriented control group. Conclusion: Only a training regime that includes a significant amount of HIIT improves the neuromuscular status, anaerobic power and the acute HRR in well-trained endurance athletes. A training regime that followed more a low and moderate intensity oriented model (CG/HVLIT) had no effect on any performance or HRR outcomes. PMID:28824457

    There are few published estimates of anal human papillomavirus (HPV) infection rates among young men who have sex with men (YMSM). We estimated incidence and prevalence of type-specific anal HPV infection using clinician-collected anal swabs for HPV DNA testing obtained during a 1-year prospective study of 94 YMSM (mean age, 21 years) in Seattle. Seventy percent of YMSM had any HPV infection detected during the study, and HPV-16 and/or -18 were detected in 37%. The incidence rate for any new HPV infection was 38.5 per 1000 person-months and 15.3 per 1000 person-months for HPV-16/18; 19% had persistent HPV-16/18 infection. No participant tested positive for all 4 HPV types in the quadrivalent vaccine. The number of lifetime male receptive anal sex partners was significantly associated with HPV infection. The prevalence of HPV-16/18 was 6% among YMSM with a history of 1 receptive anal sex partner and 31% among YMSM with ≥ 2 partners. Although the high prevalence of HPV among YMSM highlights the desirability of vaccinating all boys as a strategy to avert the morbidity of HPV infection, most YMSM appear to remain naive to either HPV-16 or -18 well into their sexual lives and would benefit from HPV immunization.

    Intimate partner violence (IPV) is a significant public health problem in South Africa. However, limited research exists on IPV during pregnancy and the postpartum period in South Africa. The purpose of this study is to describe the prevalence, rates and correlates of IPV among South African women during pregnancy and the first 9 months postpartum. Data are from a longitudinal study with women recruited during pregnancy between 2008 and 2010 at a public clinic in Durban. We used a modified version of the World Health Organization's IPV scale to estimate prevalence and rates of IPV during pregnancy, at 4 months postpartum and 9 months postpartum and we used logistic regression to assess the correlates of IPV during this time. More than 20 % of all women experienced at least one act of physical, psychological or sexual IPV during pregnancy. Nearly one-quarter of all women experienced at least one act of physical, psychological or sexual IPV during the first 9 months postpartum. Psychological IPV was the most prevalent type of IPV during pregnancy and the first 4 months postpartum. Age and previous violence within the relationship were associated with IPV during pregnancy and IPV during the postpartum period. The high levels of IPV during pregnancy and the postpartum period highlight the need to develop screening and intervention strategies specifically for this time. Further, women should be screened not only for physical violence but also psychological violence given that psychological violence may result in distinct negative consequences.

    Full Text Available The aim of this study was to estimate the dynamics of type 2 diabetes mellitus (T2DM prevalence and management rates based on a rural cohort study in Henan Province of China. The rural prospective study was conducted for 20194 Chinese population ≥18 years in 2007-2008 and followed during 2013-2014. A total of 14009 individuals were recruited for the prospective analysis ultimately. Over 5.74 years of follow-up, the age-standardized prevalence, awareness, treatment, and control of T2DM increased from 6.18%, 44.41%, 34.39%, and 19.08% at baseline to 7.87%, 59.64%, 52.17%, and 26.52% at follow-up in total population, respectively. Similar changes were found in men and women except the age-standardized control in men. The four parameters of T2DM were higher among various factors at follow-up than those at baseline. There was no statistical difference in awareness (P=0.089 and treatment (P=0.257 in the newly diagnosed T2DM compared with the rates at baseline. The current study indicated that the prevalence, awareness, treatment, and control of T2DM displayed chronological increasing trends while the awareness, treatment, and control of T2DM were still disproportionally low in central China. More works are needed urgently to popularize public health education and improve the quality of medical care in T2DM.

    Depression is a common comorbid disorder of dementia. This study explores the prevalence of and factors associated with depressive symptomatology, and antidepressant prescription rates in severe dementia across eight European countries. In total, 414 people with severe dementia completed measures of cognition and quality of life (QoL), whilst carers completed proxy measures of activities of daily living (ADLs), depression, neuropsychiatric symptoms, QoL and comorbidity. Findings indicated that 30% of the sample had depression, whilst the highest and lowest prevalence of depression was reported in Germany and Finland, respectively. Lower QoL, the presence of pain and more frequent neuropsychiatric symptoms were associated with depressive symptomatology, whilst no significant relationship between impairment of ADLs, comorbidity, and depression emerged. Spain and Estonia had the highest and lowest rates of antidepressant prescribing, respectively, whilst Germany had the highest discrepancy between depressive symptomatology and prescription. The study highlights variations across countries in the prevalence of depressive symptomatology in severe dementia and prescription of antidepressants. Information about factors associated with depressive symptomatology may help to better identify and manage depression.

A census was used as a sampling method. A self-report questionnaire regarding demographic details and ecstasy consumption was completed by students. Data was stored in a database and then was analyzed through descriptive tests by SPSS software. Chi square test was used to determine the correlation coefficient.Results: There were 798 subjects of all target population who had never used this drug. However, 132 subjects (18 regularly, 56 occasionally for fun and 58 at least once consumed ecstasy pills. Thus the point prevalence of ecstasy consumption among the students was 14.19 percent. There were 232 subjects who had never heard of the term “ecstasy". Instead, the knowledge source of the rest about ecstasy was books (116 subject, internet (56 subjects, mass media (489 subjects, friends (28 subjects, and family (2 subjects. A significant relation was observed between ecstasy consumption and other variables (parents' education, residence in student campus, attending parties, smoking, canabis and opium consumption. Conclusion: Results of this study revealed that the point prevalence of ecstasy pills consumption among university students was 14.19% that raises the need for purposive intervention and the necessity of planning to prevent and decrease this phenomenon.(Sci J Hamadan Univ Med Sci 2012;18(4:67-72

    Although it is still unclear what causes autism spectrum disorders (ASDs), over time researchers and clinicians have become more precise with detecting and diagnosing ASD. Many diagnoses, however, are based on the criteria established within the Diagnostic and Statistical Manual of Mental Disorders (DSM); thus, any change in these diagnostic criteria can have a great effect upon children with ASD and their families. It is predicted that the prevalence of ASD diagnoses will dramatically decrease with the adoption of the proposed DSM-5 criteria in 2013. The aim of this current study was to inspect the changes in prevalence first using a diagnostic criteria set which was modified slightly from the DSM-5 criteria (Modified-1 criteria) and again using a set of criteria which was relaxed even a bit more (Modified-2 criteria). Modified-1 resulted in 33.77 % fewer toddlers being diagnosed with ASD compared to the DSM-IV, while Modified-2 resulted in only a 17.98 % decrease in ASD diagnoses. Children diagnosed with the DSM-5 criteria exhibited the greatest levels of autism symptomatology, but the Mod-1, Mod-2, and DSM-IV groups still demonstrated significant impairments. Implications of these findings are discussed.

    Brain-computer interface (BCI) is technology that is developing fast, but it remains inaccurate, unreliable and slow due to the difficulty to obtain precise information from the brain. Consequently, the involvement of other biosignals to decode the user control tasks has risen in importance. A traditional way to operate a BCI system is via motor imagery (MI) tasks. As imaginary movements activate similar cortical structures and vegetative mechanisms as a voluntary movement does, heart rate variability (HRV) has been proposed as a parameter to improve the detection of MI related control tasks. However, HR is very susceptible to body needs and environmental demands, and as BCI systems require high levels of attention, perceptual processing and mental workload, it is important to assess the practical effectiveness of HRV. The present study aimed to determine if brain and heart electrical signals (HRV) are modulated by MI activity used to control a BCI system, or if HRV is modulated by the user perceptions and responses that result from the operation of a BCI system (i.e., user experience). For this purpose, a database of 11 participants who were exposed to eight different situations was used. The sensory-cognitive load (intake and rejection tasks) was controlled in those situations. Two electrophysiological signals were utilized: electroencephalography and electrocardiography. From those biosignals, event-related (de-)synchronization maps and event-related HR changes were respectively estimated. The maps and the HR changes were cross-correlated in order to verify if both biosignals were modulated due to MI activity. The results suggest that HR varies according to the experience undergone by the user in a BCI working environment, and not because of the MI activity used to operate the system. PMID:27458384

    Sagittal otoliths from two bothid flatfish species ( Citharichthys arenaceus and C. spilopterus) collected in Puerto Rico were microstructurally examined and periodic increments counted. C. arenaceus length-at-age (33 to 246 days) data were best fitted by a Gompertz growth model whose parameters were estimated to be SL ∞ = 170 mm and K = 0.0166. Adult size is reached in less than one year. The peak period of hatching occurred in late spring, and settlement took place 39 days later. Due to a smaller age range (71 to 150 days), growth of C. spilopterus was described by a linear relationship with slope = 0.693 and intercept = -15.1 days. Hatching occurred in winter and spring. These two species showed no significant difference in age at settlement. After settlement, growth of C. spilopterus (0.69 mm·d -1 at 71 to 113 days old) was significantly slower than that of C. arenaceus (1.00 mm·d -1 at 71 to 113 days) possibly due to poorer environmental (abiotic or food-related) conditions during the dry, cool season (December-April). C. spilopterus from North Carolina, hatched in the same period, settled about two weeks older than in Puerto Rico. Growth after settlement was significantly slower in North Carolina (0.44 mm·d -1 at 71 to 113 days) than in Puerto Rico. Environmental conditions (including temperature), distance between spawning areas and settlement grounds, and/or food availability, might explain the dissimilarity in growth observed between the two geographic areas. We recommend absolute field growth to be compared by using growth rates obtained by deriving the growth curve formula.

    Aim of the study was to assess both prevalence and antibiotic resistance in anaerobic bacteria from glans penis skin of 70 adults. Strain susceptibility was determined by breakpoint susceptibility test or E test. In 9 asymptomatic, 48 untreated and 13 treated symptomatic patients, anaerobes were found in 22.2%, 70.8% and 53.3%, respectively. Gram-positive strains (GPAs) were 2.2-fold more common than Gram-negative ones. Prevalent Gram-negative (GNAs) and GPAs were Prevotella spp. and anaerobic cocci, respectively. Clostridium difficile strain was found in an untreated patient. In GNAs, resistance rates to amoxicillin, metronidazole, clindamycin, tetracycline, levofloxacin, and amoxicillin/clavulanate were 42.1, 0, 52.6, 53.3, 86.7 and 5.2%, respectively. In GPAs, the resistance rates to metronidazole, clindamycin, tetracycline, levofloxacin and amoxicillin/clavulanate were 18.2, 34.1, 52.6, 36.8 and 0%, respectively. In conclusion, anaerobes were 1.6-fold more frequent in untreated symptomatic patients compared with other patients, suggesting their participation in development of chronic balanitis. GPAs were more common than GNAs. The resistance rates to amoxicillin, clindamycin, tetracycline, and levofloxacin were high. Most active agents were metronidazole and amoxicillin/clavulanate. Resistance in anaerobes varies according to sites of specimens and years of study. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Dengue is an important public health problem worldwide. A vaccine has recently been licensed in some countries of Latin America and Asia. Recommendations for dengue vaccine introduction include endemicity and a high serological prevalence of dengue in the territories considering its introduction. A community-based survey was conducted to estimate dengue seroprevalence and age-specific seroconversion rates in a community in Medellin, Colombia, using a dengue serological test (IgG indirect ELISA). Residents were selected at random and were first screened for dengue infection; they were then followed over 2.5 years. A total of 3684 individuals aged between 1 and 65 years participated in at least one survey. The overall dengue seroprevalence was 61%, and only 3.3% of seropositive subjects self-reported a past history of dengue. Among dengue virus (DENV)-naïve subjects with more than two visits (n=1002), the overall seroconversion rate was 8.7% (95% confidence interval 7.3-10.4) per 1000 person-months, over the study period. Overall, the mean age of DENV prevalent subjects was significantly higher than the mean age of seroconverted subjects. Specifically, DENV seropositivity over 70% was observed in participants over 21 years old. Serotype-specific plaque-reduction neutralization tests (PRNT) revealed that all four dengue serotypes were circulating, with DENV4 being most prevalent. These laboratory-based findings could inform dengue vaccine decisions, as they provide age-specific seroprevalence and seroconversion data, evidencing permanent and ongoing dengue transmission in the study area. This study provides evidence for the existing rates of secondary and heterotypic responses, presenting a challenge that must be addressed adequately by the new vaccine candidates.

    The aim of this study was to investigate the dental status of alcoholics; to evaluate the relationship of unstimulated and stimulated saliva pH on their decayed/missing/filled teeth (DMFT); and to evaluate the relationship of unstimulated and stimulated salivary flow rate on their DMFT. A cross-sectional study was conducted in patients treated for alcohol dependency (n = 70; mean age 41.7 years) and a control group of non-alcoholics (n = 70; mean age 39.1 years). Examinations for dental caries were conducted using the World Health Organization (WHO) criteria and questionnaires. The correlation between nominal variables was determined using chi2 test (alpha = 0.05). The correlation between interval variables was determined using Pearson's correlation coefficient. The mean DMFT was similar in alcoholics (14.40) and the control group (13.44) (p > 0.05). There was a statistically significant correlation between alcoholism and unstimulated salivary flow rate (p salivary flow rate (p > 0.05) or stimulated salivary flow on DMFT (p > 0.05). There was a statistically significant correlation between alcoholism and the pH value of stimulated saliva (p 0.05). No major differences were found with respect to overall DMFT in alcoholics compared to the control group. Alcoholism and stimulated salivary flow rate showed no correlation. Unstimulated salivary flow rate as well as the pH values of both unstimulated and stimulated saliva, were lower in the alcoholic group.

    To examine the effect of heterogeneous case mix for a benchmarking analysis and interhospital comparison of the prevalence rates of nosocomial infection. Cross-sectional survey. Eleven hospitals located in Cyprus and in the region of Crete in Greece. The survey included all inpatients in the medical, surgical, pediatric, and gynecology-obstetrics wards, as well as those in intensive care units. Centers for Disease Control and Prevention criteria were used to define nosocomial infection. The information collected for all patients included demographic characteristics, primary admission diagnosis, Karnofsky functional status index, Charlson comorbidity index, McCabe-Jackson severity of illness classification, use of antibiotics, and prior exposures to medical and surgical risk factors. Outcome data were also recorded for all patients. Case mix-adjusted rates were calculated by using a multivariate logistic regression model for nosocomial infection risk and an indirect standardization method.Results. The overall prevalence rate of nosocomial infection was 7.0% (95% confidence interval, 5.9%-8.3%) among 1,832 screened patients. Significant variation in nosocomial infection rates was observed across hospitals (range, 2.2%-9.6%). Logistic regression analysis indicated that the mean predicted risk of nosocomial infection across hospitals ranged from 3.7% to 10.3%, suggesting considerable variation in patient risk. Case mix-adjusted rates ranged from 2.6% to 12.4%, and the relative ranking of hospitals was affected by case-mix adjustment in 8 cases (72.8%). Nosocomial infection was significantly and independently associated with mortality (adjusted odds ratio, 3.6 [95% confidence interval, 2.1-6.1]). The first attempt to rank the risk of nosocomial infection in these regions demonstrated the importance of accounting for heterogeneous case mix before attempting interhospital comparisons.

  15. HCV infection among Saudi population: high prevalence of genotype 4 and increased viral clearance rate.

    Ahmed S Abdel-Moneim

    Full Text Available HCV is a major etiological agent of liver disease with a high rate of chronic evolution. The virus possesses 6 genotypes with many subtypes. The rate of spontaneous clearance among HCV infected individuals denotes a genetic determinant factor. The current study was designed in order to estimate the rate of HCV infection and ratio of virus clearance among a group of infected patients in Saudi Arabia from 2008 to 2011. It was additionally designed to determine the genotypes of the HCV in persistently infected patients. HCV seroprevalence was conducted on a total of 15,323 individuals. Seropositive individuals were tested by Cobas AmpliPrep/Cobas TaqMan HCV assay to determine the ratio of persistently infected patients to those who showed spontaneous viral clearance. HCV genotyping on random samples from persistently infected patients were conducted based on the differences in the 5'untranslated region (5'UTR. Anti-HCV antibodies were detected in 7.3% of the totally examined sera. A high percentage of the HCV infected individuals experienced virus clearance (48.4%. HCV genotyping revealed the presence of genotypes 1 and 4, the latter represented 97.6% of the tested strains. Evidences of the widespread of the HCV genotype 4 and a high rate of HCV virus clearance were found in Saudi Arabia.

    Although malaria has been traditionally regarded as less of a problem in urban areas compared to neighbouring rural areas, the risk of malaria infection continues to exist in densely populated, urban areas of Africa. Despite the recognition that urbanization influences the epidemiology of malaria, there is little consensus on urbanization relevant for malaria parasite mapping. Previous studies examining the relationship between urbanization and malaria transmission have used products defining urbanization at global/continental scales developed in the early 2000s, that overestimate actual urban extents while the population estimates are over 15 years old and estimated at administrative unit level. This study sought to discriminate an urbanization definition that is most relevant for malaria parasite mapping using individual level malaria infection data obtained from nationally representative household-based surveys. Boosted regression tree (BRT) modelling was used to determine the effect of urbanization on malaria transmission and if this effect varied with urbanization definition. In addition, the most recent high resolution population distribution data was used to determine whether population density had significant effect on malaria parasite prevalence and if so, could population density replace urban classifications in modelling malaria transmission patterns. The risk of malaria infection was shown to decline from rural areas through peri-urban settlements to urban central areas. Population density was found to be an important predictor of malaria risk. The final boosted regression trees (BRT) model with urbanization and population density gave the best model fit (Tukey test p value <0.05) compared to the models with urbanization only. Given the challenges in uniformly classifying urban areas across different countries, population density provides a reliable metric to adjust for the patterns of malaria risk in densely populated urban areas.

    Simpson, Gloria A; Colpe, Lisa; Greenspan, Stanley

    2003-01-01

    In order to measure the prevalence of developmental delay among US infants and children, two types of questions were asked of parents in the 1994-95 National Health Interview Survey on Disability (NHIS-D). To measure functional delay (FD), questions from the Functional Developmental Growth Chart (FDQ), which measures specific age-appropriate tasks, were used. General delay (GD) was defined using the general type of questions about developmental delay that had been used in previous surveys. Using a nationally representative sample of 15 291 infants and children aged 4-59 months from the NHIS-D, analyses revealed that, according to these questions, approximately 3.3% had FD and 3.4% of the children had GD. However, only one-third of the children were identified by both sets of questions. Thus, two-thirds of the children identified as having FD were not recognised by their parents as having a delay. Conversely, many parents responded to the GD questions indicating that their child had a delay, but failed to indicate that their child had a functional problem. In addition, only 17% of the children with FD and 31% of those with GD were receiving special services. Multivariable logistic regression analyses found that children with both FD and GD were more likely to be male and to be living in families with incomes below 200% of the poverty level. The findings suggest that the general types of developmental delay questions used in national surveys may not identify children with functional delays. As parents failed to identify these children, it is possible that many of these children may be slipping through paediatric surveillance. Further research to evaluate the use of these measures in population surveys is recommended.

    2009-01-01

    With this study we aimed to compare survival rates for children with Down syndrome in 2 time periods, 1 before prenatal screening (1988-1990) and 1 contemporaneous with screening (1998-2000), and to examine the frequency of comorbidities and their influence on survival rates. Record-linkage was performed between the population-based Victorian Birth Defects Register and records of deaths in children up to 15 years of age collected under the auspice of the Consultative Council on Obstetric and Pediatric Mortality and Morbidity. Cases of Down syndrome were coded according to the presence or absence of comorbidities by using the International Classification of Diseases, Ninth Revision classification of birth defects. Kaplan-Meier survival functions and log rank tests for equality of survival distributions were performed. Of infants liveborn with Down syndrome in 1998-2000, 90% survived to 5 years of age, compared with 86% in the earlier cohort. With fetal deaths excluded, the proportion of isolated Down syndrome cases in the earlier cohort was 48.7% compared with 46.1% in the most recent cohort. In 1988-1990 there was at least 1 cardiac defect in 41.1% of cases and in 45.4% in 1998-2000. There was significant variation in survival rates for the different comorbidity groupings in the 1988-1990 cohort, but this was not so evident in the 1998-2000 cohort. Survival of children with Down syndrome continues to improve, and there is an overall survival figure of 90% to at least 5 years of age. It is clear from this study that prenatal screening technologies are not differentially ascertaining fetuses with Down syndrome and additional defects, because there has been no proportional increase in births of isolated cases with Down syndrome.

    Several endoparasites of dogs cannot only be detrimental to their primary host but might also represent a threat to human health because of their zoonotic potential. Due to their high dog population densities, metropolitan areas can be highly endemic for such parasites. We aimed to estimate the prevalence of endoparasites in dogs in the Austrian capital of Vienna by examining a representative number of canine faecal samples and to compare the prevalences with two neighbouring peri-urban and rural regions. In addition we analysed whether the density of dog populations and cleanliness of dog zones correlated with parasite occurrence. We collected 1001 anonymous faecal samples from 55 dog zones from all 23 districts of the federal state of Vienna, as well as 480 faecal samples from the Mödling district and Wolkersdorf with a peri-urban and rural character, respectively. Faeces were examined by flotation and by Baermann technique. Additionally we evaluated 292 Viennese, 102 peri-urban and 50 rural samples for Giardia and Cryptosporidium by GiardiaFASTest ® and CryptoFASTest ® . Samples from "clean" dog zones were compared to samples from "dirty" zones. The infection rate of Toxocara was surprisingly low, ranging from 0.6% to 1.9%. Trichuris was the most frequent helminth (1.8-7.5%) and Giardia the most frequent protozoan (4.0-10.8%). Ancylostomatidae, Crenosoma, Capillaria, Taeniidae, Cystoisospora and Sarcocystis were found in 1.8-2.2%, 0-0.9%, 0-0.9%, 0-0.6%, 0.3-3.1% and 0-0.6% of the samples, respectively. Samples from "dirty" dog zones in Vienna showed a significantly higher rate of parasites overall (p=0.003) and of Trichuris (p=0.048) compared to samples from "clean" dog zones. There were no statistically significant differences in densely vs. less densely populated areas of Vienna. Samples from the rural region of Wolkersdorf had significantly higher overall parasite, Trichuris and Cystoisospora prevalences than the peri-urban Mödling district and Vienna (p

  4. Gender differences in drunk driving prevalence rates and trends: a 20-year assessment using multiple sources of evidence.

    2008-09-01

    This research tracked women's and men's drunk driving rates and the DUI sex ratio in the United States from 1982-2004 using three diverse sources of evidence. Sex-specific prevalence estimates and the sex ratio are derived from official arrest statistics from the Federal Bureau of Investigation, self-reports from the Centers for Disease Control and Prevention, and traffic fatality data from the National Highway and Transportation Safety Administration. Drunk driving trends were analyzed using Augmented Dickey Fuller time series techniques. Female DUI arrest rates increased whereas male rates declined then stabilized, producing a significantly narrower sex ratio. According to self-report and traffic data, women's and men's drunk driving rates declined and the gender gap was unchanged. Women's overrepresentation in arrests relative to their share of offending began in the 1990s and accelerated in 2000. Women's arrest gains, contrasted with no systematic change in DUI behavior, and the timing of this shift suggest an increased vulnerability to arrest. More stringent laws and enforcement directed at less intoxicated offenders may inadvertently target female offending patterns.

    The prevalence of disability varies between countries ranging from less than 1% to up to 30% in some countries, thus, the estimated global disability prevalence is about 15%. However, it is unknown what the current estimate of disability and its types and severity are in Saudi Arabia. Thus, the objective of this study is to estimate national and regional prevalence rates of any disability, types of disability, and their severity among Saudi populations. Data on disability status were extracted from the national demographic survey conducted in 2016 as reported by the General Authority for Statistics, Saudi Arabia (N = 20,064,970). Prevalence rates per a population of 100,000 of any disability, type of disability, and its severity were calculated at the national level and in all 13 regions. Out of 20,064,970 Saudi citizens surveyed, 667,280 citizens reported disabilities, accounting for a prevalence rate of 3326 per a population of 100,000 (3.3%). Individuals aged 60 years and above (11,014) and males (3818) had a higher prevalence rate of disability compared with females (2813). The Tabuk region has the highest rate of reported disability, at 4.3%. The prevalence rates of extreme disabilities in mobility and sight were higher in Madinah (57,343) and Northern border (41,236) regions, respectively. In Saudi Arabia, more than half a million Saudi citizens (1 out of every 30 individuals) reported the presence of disability during the year 2016. A higher prevalence rate of disability was seen among those aged 60 years and above, and males. Targeted efforts are required at the national and regional levels to expand and improve rehabilitation and social services for all people with disabilities.

    Full Text Available Abstract Background The patterns of mutation vary both within and across genomes. It has been shown for a few mammals that mutation rates vary within the genome, while for unknown reasons, the sensu stricto yeasts have uniform rates instead. The generality of these observations has been unknown. Here we examine silent site substitutions in a more expansive set (20 mammals, 27 fungi, 4 insects to determine why some genomes demonstrate this mosaic distribution and why others are uniform. Results We applied several intragene and intergene correlation tests to measure regional substitution patterns. Assuming that silent sites are a reasonable approximation to neutrally mutating sequence, our results show that all multicellular eukaryotes exhibit mutational heterogeneity. In striking contrast, all fungi are mutationally uniform – with the exception of three Candida species: C. albicans, C. dubliniensis, and C. tropicalis. We speculate that aspects of replication timing may be responsible for distinguishing these species. Our analysis also reveals classes of genes whose silent sites behave anomalously with respect to the mutational background in many species, indicating prevalent selective pressures. Genes associated with nucleotide binding or gene regulation have consistently low silent substitution rates in every mammalian species, as well as multiple fungi. On the other hand, receptor genes repeatedly exhibit high silent substitution rates, suggesting they have been influenced by diversifying selection. Conclusion Our findings provide a framework for understanding the regional mutational properties of eukaryotes, revealing a sharp difference between fungi and multicellular species. They also elucidate common selective pressures acting on eukaryotic silent sites, with frequent evidence for both purifying and diversifying selection.

    Objectives To update UK studies begun in the early 1990s on the annual prevalence and incidence rates of autism in children; undertaken in response to a March 2012 press release, widely covered by the media, from the US Centre for Disease Control (CDC) reporting that the autism prevalence rate in 2008 in 8-year-old US children was 1 in 88, a 78% increase from a CDC estimate in 2004. This finding suggested a continuation of the dramatic increase in children diagnosed as autistic, which occurred in the 1990s. Design Population study using the UK General Practice Research Database (GPRD). Methods Annual autism prevalence rates were estimated for children aged 8 years in 2004–2010 by dividing the number diagnosed as autistic in each or any previous year by the number of children active in the study population that year. We also calculated annual incidence rates for children aged 2–8 years, by dividing the number newly diagnosed in 2004–2010 by the same denominators. Results Annual prevalence rates for each year were steady at approximately 3.8/1000 boys and 0.8/1000 girls. Annual incidence rates each year were also steady at about 1.2/1000 boys and 0.2/1000 girls. Conclusions Following a fivefold increase in the annual incidence rates of autism during the 1990s in the UK, the incidence and prevalence rates in 8-year-old children reached a plateau in the early 2000s and remained steady through 2010. Whether prevalence rates have increased from the early 2000s in the USA remains uncertain. PMID:24131525

    Full Text Available Linguatla serrata is a zoonotic parasite which causes different forms of liguatulosis in humans, carnivores and ruminants. The most important way of human infection is injection of vegetables, fruits and water contaminated by parasite eggs and through nasal and oral secretions and feces of carnivorous especially stray dogs. Also, consumption of raw and under cook meat of sheep, goats, cattle and other herbivores is another risk factor in human infection by Linguatla serrata.  This study was conducted in order to determine the infection rate of dogs by Linguatla serrata in the city of Urmia. In the present study, 37 dogs including 22 male and 15 female animals from different parts of the city were studied. The frontal sinuses, nasal turbinates, brain cavity, nasopharynx and eustachian tubes were examined for adult Linguatla serrata. The recovered parasites were fixed in 10% formalin solution, cleared by lactophenol and stained with azocarmin. Thirty of the studied dogs (81.01% were infected by Linguatla serrata. The results indicated that body weight, age, sex and geographical locations had no significant effect in the prevalence rate of the parasite. The number of parasites recovered from each dog ranged from 1 to 7 with an average of 2.93 in each dog. The length of the mature linguatula varied from 35-50 mm in females and 2-18 mm in males. The greatest number of parasites was found in the cranial part of the frontal sinus with 7 parasites.

    The validity of borderline personality disorder (BPD) in children and adolescents has not been studied in a rigorous manner reflecting the criteria of Robins and Guze first detailed in 1970. This paper and the others in this series address some aspects of this multifaceted validation paradigm, which requires that a disorder has a known clinical presentation, can be delimited from other disorders, 'runs' in families, and something of its aetiology, treatment response and course is known. Three groups of subjects were studied: 104 adolescent inpatients meeting the Revised Diagnostic Interview for Borderlines and DSM-IV criteria for BPD, 60 psychiatrically healthy adolescents and 290 adult inpatients meeting the Revised Diagnostic Interview for Borderlines and DSM-III-R criteria for BPD. Adolescents with BPD had significantly higher prevalence rates of 22 of the 24 symptoms studied than psychiatrically healthy adolescents. Only rates of serious treatment regressions and countertransference problems failed to reach the Bonferroni-corrected level of 0.002. Adolescents and adults with BPD had only four symptomatic differences that reached this level of significance, with adolescents with BPD reporting significantly lower levels of quasi-psychotic thought, dependency/masochism, devaluation/manipulation/sadism and countertransference problems than adults with BPD. Taken together, the results of this study suggest that adolescents report BPD as severe as that reported by adults. They also suggest that BPD in adolescents is not a tumultuous phase of normal adolescence. Copyright © 2017 John Wiley & Sons, Ltd. Copyright © 2017 John Wiley & Sons, Ltd.

    Full Text Available Owing to the increasing epidemiological and therapeutic challenges associated with infections due to ESBL producers, ESBL prevalence rate among some bacteria isolates from healthy and non-healthy human population in a metropolitan Nigerian setting was evaluated.A total of one hundred and forty-five (145 bacteria strains were isolated from a total of four hundred and sixty (460 samples collected from urine, wound, throat and anal swabs of 220 healthy volunteers in the community and from 240 patients in 2 secondary and 2 tertiary hospitals (altogether, 4 in Enugu metropolis. The presumptive confirmatory test used for ESBL detection was the Double Disc Synergy Test (DDST method. Conjugation and plasmid curing studies were also done for resistance factor determination.Of the 145 isolates, 20 were ESBL producers with 35% of these ESBL producers being of community origin and 65% from hospitals. This translates to 4.8% and 9% incidences (comparably higher than established prevalence of 4.4% and 7.5 respectively for community and hospital infections respectively. The ESBL isolates showed high resistance to tetracycline, gentamicin, pefloxacin, ceftriaxone, cefuroxime, ciprofloxacin and Augmentin® (Amoxicilin and clavulanic acid combination. Conjugation studies for Resistance plasmid transfer showed non-transference of resistance determinants between the ESBL transconjugants and recipient strains. Correspondingly, the plasmid curing studies revealed that the acridine orange could not effect a cure on the isolates as they still retained high resistance to the antibiotics after the treatment.This study confirms the growing incidences/pool of ESBL strains in Nigeria and call for widespread and continuous monitoring towards an effective management of the potential therapeutic hurdle posed by this trend.

    Full Text Available Abstract Background Two large independent studies funded by the US government have assessed the impact of the Vietnam War on the prevalence of PTSD in US veterans. The National Vietnam Veterans Readjustment Study (NVVRS estimated the current PTSD prevalence to be 15.2% while the Vietnam Experience Study (VES estimated the prevalence to be 2.2%. We compared alternative criteria for estimating the prevalence of PTSD using the NVVRS and VES public use data sets collected more than 10 years after the United States withdrew troops from Vietnam. Methods We applied uniform diagnostic procedures to the male veterans from the NVVRS and VES to estimate PTSD prevalences based on varying criteria including one-month and lifetime prevalence estimates, combat and non-combat prevalence estimates, and prevalence estimates using both single and multiple indicator models. Results Using a narrow and specific set of criteria, we derived current prevalence estimates for combat-related PTSD of 2.5% and 2.9% for the VES and the NVVRS, respectively. Using a more broad and sensitive set of criteria, we derived current prevalence estimates for combat-related PTSD of 12.2% and 15.8% for the VES and NVVRS, respectively. Conclusion When comparable methods were applied to available data we reconciled disparate results and estimated similar current prevalences for both narrow and broad definitions of combat-related diagnoses of PTSD.

A estratégia metodológica deste estudo consistiu na realização de entrevistas estruturadas (questionário com 1.922 usuárias, entre 15 e 49 anos, em 14 serviços públicos de saúde. A análise dos dados revelou que 20% das usuárias que já engravidaram (IC95% 18,2 a 21,8 referem algum episódio de violência por parceiro íntimo na gestação. Em análise multivariada, observou-se que 'ter sofrido violência psicológica e física perpetrada por familiar', 'início da vida sexual antes dos 19 anos', 'recusa de uso de camisinha pelo parceiro', 'Transtorno Mental Comum' e 'não coabitar com parceiro' são fatores associados à violência na gestação. Conclui-se que a alta prevalência da violência por parceiro íntimo na gestação, sua associação com diversos fatores de saúde sexual, reprodutiva e mental são resultados que indicam a relevância de se tomar a violência como questão de saúde.OBJECTIVES: To examine the prevalence of IPV (intimate partner violence during pregnancy and its association with demographic and reproductive, sexual and mental health factors among public health care users in São Paulo, Brazil.

    To examine the radiogenic risk of latent thyroid cancer, thyroid adenoma, colloid/adenomatous goiter and chronic thyroiditis, the date for 3821 subjects collected in the course of autopsies of atomic bomb survivors in Hiroshima from 1951 to 1985 by the Radiation Effects Research Foundation (RERF) were analyzed using a logistic model. About 80% of the autopsies were performed at RERF and the remainder at local hospitals. The frequencies of the above diseases were not associated with whether the underlying cause of death was cancer. However, note that our results may be influenced by potentially biasing factors associated with autopsy selection. The relative frequency of latent thyroid cancer (greatest dimension ≤1.5 cm but detectable on a routine microscopic slide of the thyroid gland) increased as the radiation dose increased and was about 1.4-fold greater at 1 Gy than in the 0-Gy dose group. The relative occurrence of thyroid adenoma also increased as radiation dose increased, and was about 1.5-fold greater at 1 Gy than in the 0-Gy dose group. Sex, age at the time of the bombing or period of observation did not significantly modify the radiogenic risks for thyroid adenoma or latent thyroid cancer. No statistically significant association was found between radiation exposure and the rates of colloid/adenomatous goiter and chronic thyroiditis. The possible late effect of atomic bomb radiation on the frequency of benign thyroid diseases is discussed on the basis of these data. 38 refs., 2 figs., 5 tabs

    The objective of this study was to systematically review the literature on the prevalence of eating disorders (EDs) during the DSM-5 era, and to report rates of point- and lifetime prevalence. A PubMed search was conducted targeting articles on the epidemiology of EDs, in particular, reported rates of prevalence. The review was performed in accordance with PRISMA guidelines, and was limited to DSM-5 based eating disorder diagnoses published between 2012 and 2017. A total of 19 studies fulfilled inclusion criteria and were included in the study. Following the transition to DSM-5, it is evident that the prevalence of eating disorder not otherwise specified (EDNOS)/other specified feeding and eating disorders (OSFED) has decreased as intended, and there is preliminary evidence suggesting that rates of anorexia nervosa (AN) and bulimia nervosa (BN) and binge eating disorder (BED) have increased. Further, we observed higher rates of BED prevalence among females compared to males, with rates increasing with age. A limitation to the study was the search date, and that none of the included studies investigated the "new" DSM-5 feeding disorders avoidant restrictive food intake disorder (ARFID), pica or rumination disorder warranting attention in future studies investigating the epidemiology of feeding and eating disorders.

Clinical and radiological examinations were performed with the aim to identify the presence and progression of scoliosis. Methods and cohort 185 patients were recruited and a database incorporating the age at commencement, dose and frequency of growth hormone treatment and growth charts was compiled from their Medical Records. The presence of any known syndrome and the clinical presence of scoliosis were included for analysis. Subsequently, skeletally immature patients identified with scoliosis were followed up over a period of a minimum four years and the radiologic type, progression and severity (Cobb angle of scoliosis were recorded. Results Four (3.6% of the 109 with idiopathic short stature or hormone deficiency had idiopathic scoliosis (within normal limits for a control population and scoliosis progression was not prospectively observed. 13 (28.8% of 45 with Turner syndrome had scoliosis radiologically similar to idiopathic scoliosis. 11 (48% of 23 with varying syndromes, had scoliosis. In the entire cohort, the growth rates of those with and without scoliosis were not statistically different and HGH treatment was not ceased because of progression of scoliosis. Conclusion In this study, there was no evidence of HGH treatment being responsible for progression of scoliosis in a small number of non-syndromic patients (four. An incidental finding was that scoliosis, similar to the idiopathic type, appears to be more prevalent in Turner syndrome than previously believed.

    The study was carried out on children born over a 10 year period from 1997 to 2006 in Kobe city and referred to our center for specialist audiological assessment. A total of 107 cases had a bilateral sensorineural hearing impairment averaging 25 dB or over in the better hearing ear during the study period. To ascertain causes of sensorineural hearing impairment, full medical histories were obtained with detailed family history relevant to hearing impairment and perinatal course for adverse etiological factors. The children were investigated for possible congenital infection and chromosomal anomalies. Children with positive family history of deafness in parents or siblings constituted 11.2% of cases (genetic group). Other etiological groups showed the following distribution: syndromal group 5.6%; inner ear anomalies 5.6%; perinatal group 13.1%; congenital infection 11.2%; chromosomal anomalies 16.8%; multiple congenital anomalies 5.6%; causes unknown 30.9%. The high incidence of causes unknown indicates that steps should be taken to yield a diagnosis. The total number of children born in Kobe city was 117,896 during the period from 1997 to 2005, which gave a prevalence rate of hearing impairment of 0.87/1,000 births. Newborn hearing screening identified many children earlier and also provide the opportunity to finetune the evaluation. (author)

    Self-rated health is a brief measure for general health. It is a comprehensive and sensitive index for prediction of health in future. Due to the high internet usage in medical students, the current study designed to evaluate the self-rated health (SRH) in relationship with internet addiction risk factors in medical students. This cross sectional study conducted on 254 students of Qom University of Medical Sciences 2014. Participants selected by two stage sampling method including stratified and simple random sampling. The Young's questionnaire of internet addiction and SRH question used for data collection. Chi-square, t-test, and logistic regression used in data analysis. More than 79.9% of students reported their general health good and very good. The student's mean score of general health was higher than the average. In addition, the prevalence of internet addiction was 28.7%. An inverse significant correlation observed between SRH and internet addiction score (r=-0.198, p=0.002). Using internet for Entertainment, using private Email and chat rooms were the most important predictors of affecting to internet addiction. Moreover, internet addiction is the most predictors of SRH and increased the odds of bad SRH. The good SRH of medical students was higher than general population but in health faculty' students were lower than others. Due to the effect of internet addiction on SRH and increasing trend of internet use in medical students, as well as low age of participants, attention to psychological aspects and the job expectancy in future, can effective on increasing the good SRH.

    Background: Transmission of Mycobacterium tuberculosis (M. tuberculosis) can occur in different ways. Furthermore, drug resistant in M. tuberculosis family is a major problem that creates obstacles in treatment and control of tuberculosis (TB) in the world. One of the most prevalent families of M. tuberculosis is Haarlem, and it is associated with drug resistant. Our objectives of this study were to determine the prevalence and occurrence rate of M. tuberculosis Haarlem family multi-drug resistant (MDR) in the worldwide using meta-analysis based on a systematic review that performed on published articles. Materials and Methods: Data sources of this study were 78 original articles (2002-2012) that were published in the literatures in several databases including PubMed, Science Direct, Google Scholar, Biological abstracts, ISI web of knowledge and IranMedex. The articles were systematically reviewed for prevalence and rate of MDR. Data were analyzed using meta-analysis and random effects models with the software package Meta R, Version 2.13 (P < 0.10). Results: Final analysis included 28601 persons in 78 articles. The highest and lowest occurrence rate of Haarlem family in M. tuberculosis was in Hungary in 2006 (66.20%) with negative MDR-TB and in China in 2010 (0.8%), respectively. From 2002 to 2012, the lowest rate of prevalence was in 2010, and the highest prevalence rate was in 2012. Also 1.076% were positive for MDR and 9.22% were negative (confidence interval: 95%).0020. Conclusion: Many articles and studies are performed in this field globally, and we only chose some of them. Further studies are needed to be done in this field. Our study showed that M. tuberculosis Haarlem family is prevalent in European countries. According to the presence of MDR that was seen in our results, effective control programs are needed to control the spread of drug-resistant strains, especially Haarlem family. PMID:25767526

    Greater-confinement disposal (GCD) is a general term for low-level waste (LLW) disposal technologies that employ natural and/or engineered barriers and provide a degree of confinement greater than that of shallow-land burial (SLB) but possibly less than that of a geologic repository. Thus GCD is associated with lower risk/hazard ratios than SLB. Although any number of disposal technologies might satisfy the definition of GCD, eight have been selected for consideration in this discussion. These technologies include: (1) earth-covered tumuli, (2) concrete structures, both above and below grade, (3) deep trenches, (4) augered shafts, (5) rock cavities, (6) abandoned mines, (7) high-integrity containers, and (8) hydrofracture. Each of these technologies employ several operations that are mature,however, some are at more advanced stages of development and demonstration than others. Each is defined and further described by information on design, advantages and disadvantages, special equipment requirements, and characteristic operations such as construction, waste emplacement, and closure

    Changes in our political infrastructure, the continuing frailties of our economy, and a stark growth in population, have greatly impacted upon the perceived stability of the NHS. Healthcare teams have had to adapt to these changes, and so too have the technologies upon which they rely to deliver first-class patient care. Here Sarah Hunt, marketing co-ordinator at Aid Call, assesses how the changing healthcare environment has affected one of its fundamental technologies - the nurse call system, argues the case for wireless such systems in terms of what the company claims is greater adaptability to changing needs, and considers the ever-wider range of features and functions available from today's nurse call equipment, particularly via connectivity with both mobile devices, and ancillaries ranging from enuresis sensors to staff attack alert 'badges'.

Colombia has to offer, Greater economic incentives for the exploration of new areas to expand the exploratory frontier, stimulation of exploration in areas with prospectivity for small fields. Companies may offer Ecopetrol a participation in production over and above royalties, without it's participating in the investments and costs of these fields, more favorable conditions for natural gas seeking projects, in comparison with those governing the terms for oil

    Undergoing a routine medical examination may be associated with the prevalence rate of chronic diseases from a population-based household interview survey. However, this important issue has not been examined so far. Data came from the first health service household interview of Hunan province, China, in 2013. A Rao-Scott chi-square test was performed to examine the difference in prevalence rates between subgroups. Adjusted odds ratio (OR) was calculated using the PROC SURVEYLOGISTIC procedure of SAS9.1 statistical software. In total, 24,282 residents of 8400 households were surveyed. A higher proportion of elderly adults had undergone a medical examination within the prior 12 months compared with young adults (≥65 years, 60%; 45-64 years, 46%; 18-44 years, 37%). After controlling for location, sex, and household income per capita, undergoing a medical examination was significantly associated with high prevalence rates of hypertension (adjusted OR: 2.0, 95% CI: 1.1-3.5) and of diabetes mellitus (adjusted OR: 3.3, 95% CI: 1.7-6.5) for young adults aged 18-44 years. The associations were not statistically significant for age groups 45-64 years and 65 years or older. The prevalence rates of hypertension and diabetes mellitus may be seriously underestimated for young adults not undergoing a routine medical examination in a health household interview survey.

    To examine whether physicians attend to gender prevalence data in diagnostic decision making for coronary heart disease (CHD) and to test the hypothesis that previously reported gender differences in CHD diagnostic certainty are due to discrimination arising from reliance on prevalence data ("statistical discrimination"). A vignette-based experiment of 256 randomly sampled primary care physicians conducted from 2006 to 2007. Factorial experiment. Physicians observed patient presentations of cardinal CHD symptoms, standardized across design factors (gender, race, age, socioeconomic status). Structured interview. Most physicians perceived the U.S. population CHD prevalence as higher in men (48.4 percent) or similar by gender (44.9 percent). For the observed patient, 52 percent did not change their CHD diagnostic certainty based on patient gender. Forty-eight percent of physicians were inconsistent in their population-level and individual-level CHD assessments. Physicians' assessments of CHD prevalence did not attenuate the observed gender effect in diagnostic certainty for the individual patient. Given an adequate presentation of CHD symptoms, physicians may deviate from their prevalence data during diagnostic decision making. Physicians' priors on CHD prevalence did not explain the gender effect in CHD certainty. Future research should examine personal stereotypes as an explanation for gender differences.

    Moderate acute malnutrition (MAM), defined as weight-for-length z score between -3 and -2 or midupper arm circumference between 11.5 and 12.5 cm, affects ∼33 million children aged health centers in rural Mali were randomly assigned to provide to 1264 MAM children aged 6-35 mo one of 4 dietary supplements containing ∼500 kcal/d for 12 wk: 1) ready-to-use, lipid-based supplementary food (RUSF); 2) special corn-soy blend (CSB++); 3) locally processed, fortified flour (Misola); or 4) locally milled flours plus oil, sugar, and micronutrient powder (LMF). In total, 1178 children (93.2%) completed the study. The adjusted mean (95% CI) change in weight (kg) from baseline was greater with RUSF than with the locally processed blends and was intermediate with CSB++ [1.16 (1.08, 1.24) for RUSF, 1.04 (0.96, 1.13) for CSB++, 0.91 (0.82, 0.99) for Misola, and 0.83 (0.74, 0.92) for LMF; P < 0.001]. For length change, RUSF and CSB++ differed significantly from LMF. Sustained recovery rates were higher with RUSF (73%) than with Misola (61%) and LMF (58%), P < 0.0001; CSB++ recovery rates (68%) did not differ from any of the other groups. RUSF was more effective, but more costly, than other dietary supplements for the treatment of MAM; CSB++ yielded intermediate results. The benefits of treatment should be considered in relation to product costs and availability. © 2015 American Society for Nutrition.

    Full Text Available BackgroundWe investigated the prevalence, awareness, treatment, and control rate of hypertension in Korean adults with diabetes using nationally representative data.MethodsUsing data of 5,105 adults from the fifth Korea National Health and Nutrition Examination Survey in 2011 (4,389 nondiabetes mellitus [non-DM], 242 newly diagnosed with DM (new-DM, and 474 previously diagnosed with DM (known-DM, we analyzed the prevalence of hypertension (mean systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or use of antihypertensive medication and control rate of hypertension (blood pressure [BP] <130/80 mm Hg.ResultsThe prevalence of hypertension in diabetic adults was 54.6% (44.4% in new-DM and 62.6% in known-DM, P<0.0001 and P<0.0001, respectively compared with non-DM adults (26.2%. Compared to non-DM, awareness (85.7%, P<0.001 and treatment (97.0%, P=0.020 rates were higher in known-DM, whereas no differences were found between new-DM and non-DM. Control rate among all hypertensive subjects was lower in new-DM (14.9%, compared to non-DM (35.1%, P<0.001 and known-DM (33.3%, P=0.004. Control rate among treated subjects was also lower in new-DM (25.2%, compared to non-DM (68.4%, P<0.0001 and known-DM (39.9%, P<0.0001.ConclusionHigher prevalence and low control rate of hypertension in adults with diabetes suggest that stringent efforts are needed to control BP in patients with diabetes, particularly in newly diagnosed diabetic patients.

    To study the prevalence of parent-rated attention deficit hyperactivity disorder and associated parent-related factors in primary school children of Navi Mumbai. One hundred twenty two children including both boys and girls aged between 6 y and 11 y were selected from a school at Navi Mumbai and their parents were given the National Innovative for Children's Healthcare Quality (NICHQ) Vanderbilt Assessment Scale to be filled and returned, which was subsequently analyzed using SPSS (version 16). The prevalence of attention deficit hyperactivity disorder was 12.3 % with boy to girl ratio of 3:2. It was more prevalent in nuclear type of family and in families where a single parent was working especially where the father was the sole breadwinner and doing semi-skilled or unskilled type of work. No significant relation was found between the numbers of work-related hours when parents were away from children and attention deficit hyperactivity disorder. Attention deficit hyperactivity disorder is prevalent in the primary school-going population of Navi Mumbai, especially in boys. The increased prevalence in nuclear families and families with single working parent should further be explored. Further studies with larger sample size and longer period of follow up may be recommended. The study also recommends screening of school children for symptoms of attention deficit hyperactivity disorder (ADHD) for early diagnosis and treatment.

    Schizophrenia is associated with recurrent hospitalizations, need for long-term community support, poor social functioning, and low employment rates. Despite the wide- ranging financial and social burdens associated with the illness, there is great uncertainty regarding prevalence, employment rates, and the societal costs of schizophrenia. The current study investigates 12-month prevalence of patients treated for schizophrenia, employment rates, and cost of schizophrenia using a population-based top-down approach. Data were obtained from comprehensive and mandatory health and welfare registers in Norway. We identified a 12-month prevalence of 0.17% for the entire population. The employment rate among working-age individuals was 10.24%. The societal costs for the 12-month period were USD 890 million. The average cost per individual with schizophrenia was USD 106 thousand. Inpatient care and lost productivity due to high unemployment represented 33% and 29%, respectively, of the total costs. The use of mandatory health and welfare registers enabled a unique and informative analysis on true population-based datasets. © The Author 2015.

    Full Text Available Background & Objective: Campylobacter can be transmitted through the raw milk. The purpose of this study was to determine the prevalence of Campylobacter genus and Campylobacter jejuni (C. jejuni species in raw milk samples. Materials & Methods: In this study, 72 samples of raw milk were collected of the platforms milk in the Amol city in summer. Phenotypic identification of Campylobacter genus and C. jejuni species using microbiology laboratory methods and molecular identification of this bacterium using Multiplex- Polymerase Chain Reaction (M-PCR were performed. The data was calculated using the SPSS 16.0 software and the Fisher's exact test (p < 0.05. Results: Among the 72 samples, 13.88% of samples were contaminated with C. jejuni and 2.77% were contaminated with Campylobacter genus. The highest prevalence rate for this bacterium was in July (20.83% and the lowest prevalence rate was in September (12.5%. The significant difference between the prevalence of the Campylobacter genus and C. jejuni species in raw milk samples in various months of summer was not observed (p = 0.07. Conclusion: This study showed the raw milk contamination with Campylobacter, and thereby the sanitation in the dairy food production places and the use of fast and accurate method to identify this bacterium is important.

    2017-08-01

    Full Text Available Objective: To classify a rural community sample by their modifiable health behaviours and identify the prevalence of chronic conditions, poor self-rated health, obesity and hospital use. Method: Secondary analysis of a cross- sectional self-report questionnaire in the Hume region of Victoria, Australia. Cluster analysis using the two-step method was applied to responses to health behaviour items. Results: 1,259 questionnaires were completed. Overall 63% were overweight or obese. Three groups were identified: ‘Healthy Lifestyle’ (63%, ‘Non Smoking, Unhealthy Lifestyle’ (25% and ‘Smokers’ (12%. ‘Healthy lifestyle’ were older and more highly educated than the other two groups while ‘Non Smoking, Unhealthy Lifestyle’ were more likely to be obese. ‘Smokers’ had the highest rate of poor self-rated health. Prevalence of chronic conditions was similar in each group (>20%. ‘Smokers’ were twice as likely to have had two or more visits to hospital in the preceding year even after adjustment for age, gender and education. Conclusion: High rates of overweight and obesity were identified but ‘Smokers’ were at the greatest risk for poor self-rated health and hospitalisation. Implications for Public Health: Within an environment of high rates of chronic ill health and obesity, primary care clinicians and public health policy makers must maintain their vigilance in encouraging people to quit smoking.

    The objective of this paper was to systematically review the literature on the prevalence of selected infectious diseases among migrants/refugees of African origin and to provide policy makers and health care professionals with evidence-based information. We pursued a systematic review and meta-analysis to determine the prevalence of six selected infectious diseases (i.e., syphilis, helminthiasis, schistosomiasis, intestinal protozoa infections, hepatitis B, and hepatitis C) among migrants/refugees of African origin. Three electronic databases (i.e., PubMed, EMBASE, and ISI Web of Science) were searched without language restrictions. Relevant data were extracted and random-effects meta-analyses conducted. Only adjusted estimates were analyzed to help account for heterogeneity and potential confounding. We assessed the quality of evidence using the GRADE approach. The results were stratified by geographical region. Ninety-six studies were included. The evidence was of low quality due to the small numbers of countries, infectious diseases, and participants included. African migrants/refugees had median (with 95% confidence interval [95% CI]) prevalence for syphilis, helminthiasis, schistosomiasis, intestinal protozoa infection, hepatitis B, and hepatitis C of 6.0% [95% CI: 2.0-7.0%], 13.0% [95% CI: 9.5-14.5%], 14.0% [95% CI: 13.0-17.0%], 15.0% [95% CI: 10.5-21.0%], 10.0% [95% CI: 6.0-14.0%], and 3.0% [95% CI: 1.0-4.0%], respectively. We found high heterogeneity regardless of the disease (I 2 ; minimum 97.5%, maximum 99.7%). The relatively high prevalence of some infectious diseases among African migrants/refugees warrants for systematic screening. The large heterogeneity of the available published data does not allow for stratifying such screening programs according to the geographical origin of African migrants/refugees.

    The World Health Organization recently proposed significant changes to the posttraumatic stress disorder (PTSD) diagnostic criteria in the 11th edition of the International Classification of Diseases (ICD-11). The present study investigated the impact of these changes in two different post-conflict samples. Prevalence and rates of concurrent depression and anxiety, socio-demographic characteristics, and indicators of clinical severity according to ICD-11 in 1,075 Cambodian and 453 Colombian civilians exposed to civil war and genocide were compared to those according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). Results indicated significantly lower prevalence rates under the ICD-11 proposal (8.1% Cambodian sample and 44.4% Colombian sample) compared to the DSM-IV (11.2% Cambodian sample and 55.0% Colombian sample). Participants meeting a PTSD diagnosis only under the ICD-11 proposal had significantly lower rates of concurrent depression and a lower concurrent total score (depression and anxiety) compared to participants meeting only DSM-IV diagnostic criteria. There were no significant differences in socio-demographic characteristics and indicators of clinical severity between these two groups. The lower prevalence of PTSD according to the ICD-11 proposal in our samples of persons exposed to a high number of traumatic events may counter criticism of previous PTSD classifications to overuse the PTSD diagnosis in populations exposed to extreme stressors. Also another goal, to better distinguish PTSD from comorbid disorders could be supported with our data.

    Full Text Available BackgroundIt is known that metabolic syndrome (MetS is associated with chronic kidney disease. We evaluated and compared the prevalence of reduced kidney function in MetS and its components by estimated glomerular filtration rate (eGFR using an equation based on creatinine (eGFRcr, cystatin C (eGFRcys, and combined creatinine-cystatin C (eGFRcr-cys in Korean adults.MethodsWe analyzed data from 3,649 adults who participated in a comprehensive health examination.ResultsMean values of eGFRcys were higher compared with mean values of eGFRcr (96.1±18.2 mL/min/1.73 m2 vs. 91.2±13.6 mL/min/1.73 m2 in total subjects. The prevalence of reduced kidney function increased with age (9.6% for eGFRcys vs. 5.8% for eGFRcr-cys vs. 4.9% for eGFRcr, in subjects aged ≥60 years, and significantly increased with MetS, abdominal obesity, hypertension, high triglyceride, low high density lipoprotein (HDL, and high insulin resistance. The prevalence of MetS, abdominal obesity, hypertension, high insulin resistance, low HDL, and hepatic steatosis was significantly increased in subjects with reduced kidney function. This increased prevalence and the odds ratio of reduced kidney function for prevalence of MetS was highest for eGFRcys, followed by those of eGFRcr-cys, and eGFRcr.ConclusionThe prevalence of reduced kidney function by eGFR was significantly increased in subjects with MetS and its related components. eGFRcys and eGFRcr-cys were superior to eGFRcr in detecting reduced kidney function.

    Objective: The burden of noncommunicable diseases (NCDs) is increasing in China, together with economic development and social changes. The prevalence of risk factors for NCDs, such as overweight/obesity, hypertension, diabetes, and dyslipidemia, is reported to be high even among poor residents of rural areas. We aimed to investigate the prevalence of hypertension among elderly adults in rural Northeast China and the proportion with controlled hypertension among those on antihypertensive medication (hypertension control rate). We also aimed to examine the association of hypertension control with health facilities that provide treatment. Methods: We conducted a community-based cross-sectional study in six rural villages of Northeast China from February to early March, 2012. We interviewed 1593 adults aged 50-69 years and measured their blood pressure. We examined the differences in mean blood pressure between participants who obtained antihypertensive medication from village clinics and those who obtained medication from other sources, using analysis of covariance adjusted for several covariates. Results: The prevalence of hypertension among participants was as high as 63.3%, but the hypertension control rate was only 8.4%. Most villagers (98.1%) were not registered in the chronic disease treatment scheme of the public rural health insurance. The mean systolic blood pressure, adjusted for the covariates, of participants who obtained antihypertensive medication from village clinics was significantly lower than that of participants who obtained medication from township hospitals (by 16.5 mmHg) or from private pharmacies (by 7.3 mmHg). Conclusion: The prevalence of hypertension was high and the hypertension control rate low among elderly villagers during the cold season. As treatment at village clinics, which villagers can access during the cold season seems to be more effective than self-medication or treatment at distant hospitals, improving the quality of treatment

    We aimed to assess the prevalence of hypertension in an unselected human immunodeficiency virus (HIV)-infected population and to identify factors associated with hypertension prevalence, treatment, and control. We used a multicenter, cross-sectional, nationwide study that sampled 1,182 unselected, consecutive, HIV-infected patients. Office blood pressure was accurately measured with standard procedures. Patients were 71% men and 92% white, with a median age of 47 years (range = 18-78); 6% were antiretroviral treatment naive. The overall prevalence of hypertension was 29.3%; high-normal pressure accounted for an additional 12.3%. Among hypertensive subjects, 64.9% were aware of their hypertensive condition, 52.9% were treated, and 33.0% were controlled (blood pressure < 140/90 mm Hg). Blood pressure-lowering medications were used in monotherapy in 54.3% of the subjects. Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers were the most frequently used drugs (76.1%: monotherapy = 39.1%, combination treatment = 37.0%). In multivariable regression models, hypertension was independently predicted by traditional risk factors, including age ≥50 years, male sex, family history of cardiovascular disease, body mass index ≥25 kg/m2, previous cardiovascular events, diabetes, central obesity, and metabolic syndrome, as well as by duration of HIV infection, duration of antiretroviral therapy, and nadir CD4+ T-cell count <200/μl. The choice of protease inhibitors vs. nonnucleoside reverse transcriptase inhibitors as a third antiretroviral drug was irrelevant. Hypertension affects nearly 30% of HIV adult outpatients in Italy. More than one-third of the hypertensive subjects are unaware of their condition, and more than two-thirds are uncontrolled. A higher level of attention to the diagnosis and treatment of hypertension is mandatory in this setting.

  2. Estimating Plasmodium falciparum transmission rates in low-endemic settings using a combination of community prevalence and health facility data.

    Directory of Open Access Journals (Sweden)

    Joshua Yukich

    Full Text Available As some malaria control programs shift focus from disease control to transmission reduction, there is a need for transmission data to monitor progress. At lower levels of transmission, it becomes increasingly more difficult to measure precisely, for example through entomological studies. Many programs conduct regular cross sectional parasite prevalence surveys, and have access to malaria treatment data routinely collected by ministries of health, often in health management information systems. However, by themselves, these data are poor measures of transmission. In this paper, we propose an approach for combining annual parasite incidence and treatment data with cross-sectional parasite prevalence and treatment seeking survey data to estimate the incidence of new infections in the human population, also known as the force of infection. The approach is based on extension of a reversible catalytic model. The accuracy of the estimates from this model appears to be highly dependent on levels of detectability and treatment in the community, indicating the importance of information on private sector treatment seeking and access to effective and appropriate treatment.

    Media presentations of health issues affect evaluations of personal susceptibility to particular illnesses and hence help-seeking behaviours. We examined data on prevalence of eating disorders (EDs - which are often characterised as 'female') among males in: scientific literature; readily-accessible web-based information; and UK newspaper articles (published 7/12/2002-7/12/2012). This revealed conflicting statistics. Academic papers suggest men comprise around 25% of community-based samples, but much lower proportions (10% or less) of clinic samples. Websites and newspapers present widely differing statistics both on prevalence overall (numbers with EDs in the UK ranged from 60,000 to 2.7 million), and in men (generally suggesting they constituted 10-25% of those with EDs), rarely distinguishing between diagnosed and non-diagnosed samples. By 2011, newspapers were more consistent on overall numbers with EDs in the UK (1.6 million) and the proportion who were men (20%), drawing on one website as the authoritative source. Conflicting statistics may confuse men searching for ED (or other) health-related information, lead to underestimations of male susceptibility to EDs and/or reinforce inappropriate stereotypes of EDs as confined to adolescent girls.

    Diabetic retinopathy (DR) is the leading cause of blindness in working age population in developed countries. Albuminuria and estimated glomerular filtration rate (eGFR) have been considered biomarkers for DR. This study aimed to investigate the prevalence of DR and its relationship with eGFR and other risk factors in type 2 diabetic patients (T2DM) in Spain. A cross-sectional and descriptive study has been performed in 14,266 patients. Clinical records were reviewed. Demographic data, clinical diagnoses, clinical variables, and results from laboratory tests were recorded. Prevalence rates of DR were calculated. Logistic regression analysis was applied to assess predictors of the DR presence/absence. DR prevalence was 14.9%, being more prevalent in women (p = 0.0087) and in older patients (p < 0.0001). Duration of disease (OR = 5.3, IC95% = 3.8-7.4; p < 0.0001), eGFR < 60 ml/min/1.73 m 2 (OR = 2.0, IC95% 1.6-2.4; p < 0.0001), levels of HbA1c ≥ 7% (OR = 1.9, IC95% = 1.5-2.3; p < 0.0001) and high blood pressure (OR = 1.6, IC95% = 1.2-2.1; p = 0.0032) were associated with higher risk of DR. DR was also more frequent in patients taking insulin (32,6% vs. 10,2%; p < 0.0001). Around one in seven patients with T2DM has DR after nine years since diagnosis. Time since diagnosis, insulin therapy, cardiovascular profile, and renal dysfunction are associated with DR in patients with T2DM in Spain.

There were no significant differences in socio-demographic characteristics and indicators of clinical severity between these two groups. Conclusions: The lower prevalence of PTSD according to the ICD-11 proposal in our samples of persons exposed to a high number of traumatic events may counter criticism of previous PTSD classifications to overuse the PTSD diagnosis in populations exposed to extreme stressors. Also another goal, to better distinguish PTSD from comorbid disorders could be supported with our data.

    Although studies have consistently demonstrated that women at high risk for HIV and non-HIV sexually transmitted infections (STIs) tend to underestimate their individual risk, little is known about how women at risk perceive their community’s HIV/STI risk. We explored perceptions of community HIV/ STI risk among U.S. women living in areas with high poverty and HIV prevalence rates as part of a qualitative substudy of the Women’s HIV SeroIncidence Study. Semi-structured focus groups were condu...

    Conclusions: These laboratory-based findings could inform dengue vaccine decisions, as they provide age-specific seroprevalence and seroconversion data, evidencing permanent and ongoing dengue transmission in the study area. This study provides evidence for the existing rates of secondary and heterotypic responses, presenting a challenge that must be addressed adequately by the new vaccine candidates.

    Conclusion: The incidence of diabetes, including type 1, remained stable over this 10-year period in Taiwan. However, the incidence rate in men aged 20–59 years was higher than that in age-matched women. With our nationwide database, subgroup analysis of DM incidence can be performed to refine our health policies for the prevention, screening, and treatment of diabetes mellitus.

    The intracellular bacteria Coxiella (C) burnetii and Chlamydia (Chl) abortus induce abortion in sheep and also affect humans. While Chl. abortus only infrequently infects humans, C burnetii is the aetiological agent of numerous Q fever outbreaks during the last decades. There is only limited knowledge about the prevalence of both pathogens in sheep, although sheep are involved in almost all Q fever outbreaks in Germany. The aim of our study was to investigate the prevalence of both pathogens in flocks located in Lower Saxony, Germany, in correlation to the management form and abortion rate. Serum samples of 1714 sheep from 95 flocks located in Lower Saxony were investigated by ELISA. 2.7% of these samples were positive, 1.3% showed inconclusive results in the C. burnetii-ELISA. Elevated intra-flock seroprevalences were only detected in three migrating flocks. Chlamydia-specific antibodies could be detected in 15.1% serum samples of mainly shepherded and migrating flocks. In one of these flocks with a high intra-flock seroprevalence for C burnetii (27%) and Chlamydia (44.9%), C burnetii was detected in 21.6% of the placenta samples of normal births and in 12.5% of the colostrum samples by PCR. Aborted fetuses and the corresponding placentas were negative in C burnetii-PCR, but in most of them and also in many other placenta samples Chl. abortus could be detected by PCR and DNA microarray. This survey shows a low overall prevalence of C. burnetii in sheep in Lower Saxony in the year 2004. However, three migrating flocks with a high intra-flock prevalence are localized in the southern parts of Lower Saxony. Spreading of C burnetii could occur, because of the large radius of grazing of all three flocks.

    Faster eating rates are associated with increased energy intake, but little is known about the relationship between children's eating rate, food intake and adiposity. We examined whether children who eat faster consume more energy and whether this is associated with higher weight status and adiposity. We hypothesised that eating rate mediates the relationship between child weight and ad libitum energy intake. Children (n 386) from the Growing Up in Singapore Towards Healthy Outcomes cohort participated in a video-recorded ad libitum lunch at 4·5 years to measure acute energy intake. Videos were coded for three eating-behaviours (bites, chews and swallows) to derive a measure of eating rate (g/min). BMI and anthropometric indices of adiposity were measured. A subset of children underwent MRI scanning (n 153) to measure abdominal subcutaneous and visceral adiposity. Children above/below the median eating rate were categorised as slower and faster eaters, and compared across body composition measures. There was a strong positive relationship between eating rate and energy intake (r 0·61, P<0·001) and a positive linear relationship between eating rate and children's BMI status. Faster eaters consumed 75 % more energy content than slower eating children (Δ548 kJ (Δ131 kcal); 95 % CI 107·6, 154·4, P<0·001), and had higher whole-body (P<0·05) and subcutaneous abdominal adiposity (Δ118·3 cc; 95 % CI 24·0, 212·7, P=0·014). Mediation analysis showed that eating rate mediates the link between child weight and energy intake during a meal (b 13·59; 95 % CI 7·48, 21·83). Children who ate faster had higher energy intake, and this was associated with increased BMI z-score and adiposity.

    Although violent video game content and its effects have been examined extensively by empirical research, verbal aggression in the form of profanity has received less attention. Building on preliminary findings from previous studies, an extensive content analysis of profanity in video games was conducted using a sample of the 150 top-selling video games across all popular game platforms (including home consoles, portable consoles, and personal computers). The frequency of profanity, both in general and across three profanity categories, was measured and compared to games' ratings, sales, and platforms. Generally, profanity was found in about one in five games and appeared primarily in games rated for teenagers or above. Games containing profanity, however, tended to contain it frequently. Profanity was not found to be related to games' sales or platforms.

    Background Surveillance is needed to capture work organization characteristics and to identify their trends. Methods Data from the 2010 National Health Interview Survey (NHIS) were used to calculate prevalence rates for four work organization characteristics (long work hours, non-standard work arrangements, temporary positions, and alternative shifts) overall, and by demographic characteristics, and industry and occupation of current/recent employment. Results Data were available for 27,157 adults, of which 65% were current/recent workers. Among adults who worked in the past 12 months, 18.7% worked 48 hr or more per week, 7.2% worked 60 hr or more per week, 18.7% had non-standard work arrangements, 7.2% were in temporary positions, and 28.7% worked an alternative shift. Conclusions Prevalence rates of work organization characteristics are provided. These national estimates can be used to help occupational health professionals and employers to identify emerging occupational safety and health risks, allow researchers to examine associations with health, and use the data for benchmarking.

    The nationwide 'German Health Interview and Examination Survey for Children and Adolescents' (KiGGS), conducted in 2003-2006, showed an increase in the prevalence rates of overweight and obesity compared to the early 1990s, indicating the need for regular monitoring. Recently, a follow-up-KiGGS Wave 1 (2009-2012)-was carried out as a telephone-based survey, providing parent-reported height and weight from 5155 children aged 4-10 years. Since parental reports lead to a bias in prevalence rates of weight status, a correction is needed. From a subsample of KiGGS Wave 1 participants, measurements for height and weight were collected in a physical examination. In order to correct prevalence rates derived from parent reports, weight status categories based on parent-reported and measured height and weight were used to estimate a correction formula according to an established procedure. The corrected prevalence rates derived from KiGGS Wave 1 for overweight, including obesity, in children aged 4-10 years in Germany showed that stagnation is reached compared to the KiGGS baseline study (2003-2006). The rates for overweight, including obesity, in Germany have levelled off. However, they still remain at a high level, indicating a need for further public health action. What is Known: • In the last decades, prevalence of overweight and obesity has risen. Now a days, the prevalence seems to be stagnating. • In Germany, prevalence estimates of overweight and obesity are only available from regional or non-representative studies. What is New: • This article gives an update for prevalence rates of overweight and obesity amongst children aged 4-10 years in Germany based on a nationwide and representative sample. • Results show that stagnation in prevalence rates for overweight in children in Germany is reached.

    To assess the prevalence of visual impairment and rate of wearing spectacles in schools for children of migrant workers in Shanghai, China. Children from grade 1 to 5 in schools for children of migrant workers were randomly chosen for ocular examinations. All children were screened for uncorrected visual acuity and presenting visual acuity. After screening, the children whose uncorrected visual acuity was 20/40 or less received ocular motility evaluation, cycloplegic refraction/non-cycloplegic refraction, and external eye, anterior segment, media, and fundus examinations. A total of 9673 children were enumerated and 9512 (98.34%) participated in this study. The prevalence of uncorrected, presenting, and best-corrected visual acuity of 20/40 or worse in the better eye were 13.33%, 11.26%, and 0.63%, respectively. The rate of wearing spectacles of the children with visual impairment in one or both eyes was 15.50%. Of these, 26.05% were wearing spectacles with inaccurate prescriptions. Refractive error was a major cause of visual impairment, accounting for 89.48% of all the visual impairment causes. Other causes of visual impairment included amblyopia accounting for 10.12%; congenital cataract, 0.1%; congenital nystagmus, 0.1%; ocular prosthesis, 0.1%; macular degeneration, 0.05%; and opaque cornea, 0.05%. This is the first study of the prevalence and causes of visual impairment in schools for children of migrant workers in Shanghai, China. The visual impairment rate in schools for children of migrant workers in suburbs of Shanghai in the best eye before vision correction was lower than those of urban children in mainstream schools in Guangzhou in 2012, and higher than students in rural of Beijing in 1998 and in suburb of Chongqing in 2007. The refractive error was the principal cause of the visual impairment of the children of migrant workers. The rate of wearing spectacles was low and the percentage of inaccurate prescriptions, among those who wore spectacles, was

    Full Text Available The objective of this study was to investigate the self-care behaviors among hypertensive patients in primary care. A cross-sectional survey, with 318 hypertensive patients, was conducted in a rural area in Beijing, China, in 2012. Participants were mainly recruited from a community health clinic and completed questionnaires assessing their self-care behaviors, including data on adherence to a prescribed medication regimen, low-salt diet intake, smoking habits, alcohol consumption, blood pressure monitoring, and physical exercise. The logistic regression model was used for the analysis of any association between self-care behaviors and age, gender, duration of hypertension, self-rated health, marital status, education level, diabetes status, or body mass index. Subjects that adhered to their medication schedule were more likely to have hypertension for a long duration (OR, 3.44; 95% CI 1.99–5.97. Older participants (OR, 1.80; 95% CI 1.08–2.99 were more likely to monitor their blood pressure. Subjects who did not partake in physical exercise were more likely to be men, although the difference between genders was not significant (OR, 0.60; 95% CI 0.36–1.01. Patients with shorter history of hypertension, younger and being males have lower self-care behaviors. Primary care providers and public health practitioner should pay more attention to patients recently diagnosed with hypertension as well as younger male patients.

    Although studies have consistently demonstrated that women at high risk for HIV and non-HIV sexually transmitted infections (STIs) tend to underestimate their individual risk, little is known about how women at risk perceive their community's HIV/STI risk. We explored perceptions of community HIV/STI risk among U.S. women living in areas with high poverty and HIV prevalence rates as part of a qualitative substudy of the Women's HIV SeroIncidence Study. Semi-structured focus groups were conducted. Data were coded and analyzed using the constant comparative method. Participants expressed the perception that their communities were at elevated HIV/STI risk, mostly due to contextual and structural factors such as lack of access to health care and education. Findings suggest that HIV prevention messages that target U.S. women at high risk for HIV may be strengthened by addressing the high perceived community HIV/STI risk driven by structural factors.

Drug utilisation patterns for LABA have been described, but few studies have directly compared LABA use in different countries. We aimed to compare the prevalence of LABA-containing prescriptions in five European countries using a standardised methodology.A common study protocol was applied to seven European healthcare record databases (Denmark, Germany, Spain, the Netherlands (2, and the UK (2 to calculate crude and age- and sex-standardised annual period prevalence rates (PPRs of LABA-containing prescriptions from 2002-2009. Annual PPRs were stratified by sex, age, and indication (asthma, COPD, asthma and COPD.From 2002-2009, age- and sex-standardised PPRs of patients with LABA-containing medications increased in all databases (58.2%-185.1%. Highest PPRs were found in men ≥ 80 years old and women 70-79 years old. Regarding the three indications, the highest age- and sex-standardised PPRs in all databases were found in patients with "asthma and COPD" but with large inter-country variation. In those with asthma or COPD, lower PPRs and smaller inter-country variations were found. For all three indications, PPRs for LABA-containing prescriptions increased with age.Using a standardised protocol that allowed direct inter-country comparisons, we found highest rates of LABA-containing prescriptions in elderly patients and distinct differences in the increased utilisation of LABA-containing prescriptions within the study period throughout the five European countries.

    High blood pressure (hypertension) is a growing public health problem, and its impact on the overall health of patients in Africa is not well known. The objective of this study was to determine its prevalence and its influence on self-rated health among people living in rural areas of Senegal. This cross-sectional study was conducted over a two-week period in the rural communities of Labgar and Lougré Thiolly, located in the central northern region of Senegal, in an agricultural area. Randomly recruited volunteers were questioned during direct individual interviews about socio-demographic (age, sex, marital status, education, occupation) and lifestyle data (smoking or alcohol, physical activity). Clinical data (medical history, weight, height, blood pressure, course of treatment) were also collected. Self-rated health (SRH) was assessed by asking if they felt their health was bad or good. We included 627 patients with a mean age of 40.93 ± 17.2 years (range: 15-100 years), 59.9% of them women. Illiteracy and overweight were more common among women than among men, and smoking and alcohol consumption more frequent in men. The overall prevalence of hypertension was 23.4% and did not differ significantly between men (24.9%) and women (22.4%)(P = 0.50). Self-rated health was similar in men and women (with respectively 66.9% and 72.9% reporting good health, P = 0.10). On univariate analysis, the factors associated with perceived health status were age (OR = 1.34, P = 0.04), smoking (OR = 2.16, P = 0.03), educational level (OR = 1.21, P = 0.04), and the presence of hypertension (OR = 0.63, P = 0.05). The multivariate regression analysis showed that among women, advanced age (≥50 years) and hypertension (≥140/90 mmHg) were associated with poorer perceived health, whereas for men, only smoking was significantly correlated with poor health status (OR = 0.41, P = 0.01). This study shows that hypertension is common in this rural area of Senegal and is significantly

    Full Text Available Abstract Background Although causing substantial morbidity, the burden of pneumococcal disease among older children and adults in Africa, particularly in rural settings, is not well-characterized. We evaluated pneumococcal bacteremia among 21,000 persons ≥5 years old in a prospective cohort as part of population-based infectious disease surveillance in rural western Kenya from October 2006-September 2008. Methods Blood cultures were done on patients meeting pre-defined criteria - severe acute respiratory illness (SARI, fever, and admission for any reason at a referral health facility within 5 kilometers of all 33 villages where surveillance took place. Serotyping of Streptococcus pneumoniae was done by latex agglutination and quellung reaction and antibiotic susceptibility testing was done using broth microdilution. We extrapolated incidence rates based on persons with compatible illnesses in the surveillance population who were not cultured. We estimated rates among HIV-infected persons based on community HIV prevalence. We projected the national burden of pneumococcal bacteremia cases based on these rates. Results Among 1,301 blood cultures among persons ≥5 years, 52 (4% yielded pneumococcus, which was the most common bacteria isolated. The yield was higher among those ≥18 years than 5-17 years (6.9% versus 1.6%, p 95%. The crude rate of pneumococcal bacteremia was 129/100,000 person-years, and the adjusted rate was 419/100,000 person-years. Nineteen (61% of 31 patients with HIV results were HIV-positive. The adjusted rate among HIV-infected persons was 2,399/100,000 person-years (Rate ratio versus HIV-negative adults, 19.7, 95% CI 12.4-31.1. We project 58,483 cases of pneumococcal bacteremia will occur in Kenyan adults in 2010. Conclusions Pneumococcal bacteremia rates were high among persons ≥5 years old, particularly among HIV-infected persons. Ongoing surveillance will document if expanded use of highly-active antiretroviral

    Squamous cell carcinoma (SCC) is the most common malignancy of the oral cavity. A relationship between the human papilloma virus (HPV) infection and the prognosis of oral cavity SCC (OCSCC) has been discussed before. We investigated the prevalence rate of HPV status in patients with OCSCC, and its effects on clinicopathological characteristics of tumors and patients' prognosis. Sections of formalin-fixed, paraffin-embedded tissue blocks from 114 histopathologically confirmed OCSCC cases were investigated in this study. Polymerase chain reaction (PCR) was applied to evaluate the HPV status in the samples. Fifteen (13.16%) cases were identified as HPV positive. The detected viral subtypes in this study were the subtypes 6 and 11. The stage and especially lymph node stage was significantly higher in the HPV positive group compared to the HPV negative group (P = 0.04). Disease free survival (DFS) was remarkably lower in the HPV positive group compared to the HPV negative group (13.9 vs. 49.9 months, P = 0.02). Overall survival (OS) was also significantly inferior in the HPV positive group (15.7 vs. 49.6 months, P = 0.01). In the current study, no significant differences were observed between two groups in relation to the variables of age, gender, tumors site, tumor size, tumor grading and also the recurrence rate. The observed higher mortality rate among the HPV positive group indicates the poorer prognosis of this group in comparison with the HPV negative patients. The incidence rate of HPV infection was low in the studied samples; however, interaction of subtypes 6 and 11 of HPV in poorer prognosis of the patients and a carcinogenic role of HPV in OCSCC cannot be ruled out.

    The study aimed to determine if child obesity rates have risen in the Caribbean nation of Saint Lucia, as found globally, and whether under-nutrition coexists, as in other developing nations. The average adult in Saint Lucia is overweight, thus considerable child obesity might be expected, but there are no current data. Heights and weights were obtained from a sample (n= 425) of the 2001 birth cohort of Saint Lucian children measured during the nation-wide 2006/2007 Prior to School Entry Five-Year Assessment. Prevalence of overweight, obesity and underweight were estimated by Centers for Disease Control (CDC), Cole et al. and new World Health Organization (WHO) methods. Previously reported 1976 estimates, including children ≤60 months of age only, based on National Centre for Health Statistics curves, were adjusted to new WHO equivalents using an algorithm developed by Yang and de Onis, and compared with rates in our subsample of children ≤60 months of age (n= 99). Regardless of classification method, overweight and obesity rates were high: 14.4% and 9.2% (WHO); 11.3% and 12.0% (CDC); and 9.9% and 7.1% (Cole et al.), respectively. Underweight estimates also varied: 4.7% (WHO); 11.3% (CDC) and 6.6% (Cole et al.). Obesity in our young subsample (15.2%; WHO) was more than 3 times the adjusted 1976 rate (4.3%). Obesity among Saint Lucian pre-schoolers has tripled in 30 years. Our findings also suggest that this country, like many undergoing a 'nutrition transition', faces the dual challenge of over-nutrition and under-nutrition. Routine monitoring of overweight and underweight is needed in Saint Lucia, as is the implementation and evaluation of programmes to address these problems. © 2010 Blackwell Publishing Ltd.

    Full Text Available BACKGROUND: A comprehensive analysis of sex-specific differences in the characteristics, treatment, and outcomes of individuals with end-stage renal disease undergoing dialysis might reveal treatment inequalities and targets to improve sex-specific patient care. Here we describe hemodialysis prevalence and patient characteristics by sex, compare the adult male-to-female mortality rate with data from the general population, and evaluate sex interactions with mortality. METHODS AND FINDINGS: We assessed the Human Mortality Database and 206,374 patients receiving hemodialysis from 12 countries (Australia, Belgium, Canada, France, Germany, Italy, Japan, New Zealand, Spain, Sweden, the UK, and the US participating in the international, prospective Dialysis Outcomes and Practice Patterns Study (DOPPS between June 1996 and March 2012. Among 35,964 sampled DOPPS patients with full data collection, we studied patient characteristics (descriptively and mortality (via Cox regression by sex. In all age groups, more men than women were on hemodialysis (59% versus 41% overall, with large differences observed between countries. The average estimated glomerular filtration rate at hemodialysis initiation was higher in men than women. The male-to-female mortality rate ratio in the general population varied from 1.5 to 2.6 for age groups <75 y, but in hemodialysis patients was close to one. Compared to women, men were younger (mean = 61.9 ± standard deviation 14.6 versus 63.1 ± 14.5 y, were less frequently obese, were more frequently married and recipients of a kidney transplant, more frequently had coronary artery disease, and were less frequently depressed. Interaction analyses showed that the mortality risk associated with several comorbidities and hemodialysis catheter use was lower for men (hazard ratio [HR] = 1.11 than women (HR = 1.33, interaction p<0.001. This study is limited by its inability to establish causality for the observed sex

    Background : Prevalence and characteristics of fetal alcohol syndrome (FAS) and total fetal alcohol spectrum disorders (FASD) were studied in a second sample of three South African rural communities to assess change. Methods : Active case ascertainment focused on children with height, weight and/or head circumference ≤25th centile and randomly-selected children. Final diagnoses were based on dysmorphology, neurobehavioral scores, and maternal risk interviews. Results : Cardinal facial features, head circumference, and total dysmorphology scores differentiated specific FASD diagnostic categories in a somewhat linear fashion but all FASD traits were significantly worse than those of randomly-selected controls. Neurodevelopmental delays were significantly worse for children with FASD than controls. Binge alcohol use was clearly documented as the proximal maternal risk factor for FASD, and significant distal risk factors were: low body mass, education, and income; high gravidity, parity, and age at birth of the index child. FAS rates continue to extremely high in these communities at 9-129 per 1000 children. Total FASD affect 196-276 per 1000 or 20-28% of the children in these communities. Conclusions : Very high rates of FASD persist in these general populations where regular, heavy drinking, often in a binge fashion, co-occurs with low socioeconomic conditions.

    To assess the compliance of community pharmacies with the regulations that prohibit the dispensing of prescription-only medications in the absence of a physician prescription in Saudi Arabia. A cross-sectional study was conducted in the period between October 2014 and January 2015. A list of 10 prescription-only medications were selected to be studied. 150 community pharmacies were visited across 6 major regions in Saudi Arabia to assess the prevalence of non-compliance among community pharmacies. Pharmacies were selected in random and researchers (disguised as patients) requested to purchase prescription-only medications in the absence of a prescription. Not all medications were purchased at once. Data were recorded per pharmacy, where pharmacies that approved dispense of the selected drug were scored as non-compliant and the pharmacies that rejected dispense of the selected drug were scored as compliant. Compliance rate was calculated per region per drug. Pharmacies based in governmental hospitals were visited in parallel. A total of 20 were visited. Data and statistical analysis were performed using Statistical Analyses Software (SAS 9.3). A total of 150 pharmacies were visited over a period of 3 months. On average, the percent approved dispense of prescription-only drugs across 6 regions in Saudi Arabia is 63% and the percent rejected dispense is 37% representing a significant non-compliance rate regarding the selected list of medications in this study. The frequency of dispense per medication across 6 major regions in Saudi Arabia is as follows: Isosorbide dinitrate (86%), Enoxaparin (82%), nitroglycerin (74%), Propranolol (73%), Verapamil (70%), Warfarin (65%), Methyldopa (64%), Ciprofloxacin (57%) and Codeine (4%). Non-compliance of community pharmacies with the law of pharmaceutical practice is at an alarming rate in the Kingdom of Saudi Arabia and authoritative figures must intervene to impede and combat such activities .

    The prevalence rate for child sexual abuse among new psychiatric outpatients in Fort McMurray was 20.7%. With an odds ratio for sex of 3.30, female patients are about 3 times more likely to report a history of child sexual abuse compared with male patients when controlling for other factors. Similarly, patients with at most high school education and those with previous contact with psychiatric services were about 2 times more likely to report a history of child sexual abuse compared to the patients with college or university education or no previous contact with psychiatric services, respectively. Similarly, patients with histories of substance abuse and patients with family histories of mental illness had higher likelihoods of reporting histories of child sexual abuse compared to patients without histories of substance abuse or family histories of mental illness, respectively. Our findings suggest that victims of child sexual abuse are an at-risk population in need of ongoing mental health and educational support.

    Autoerotic fatalities in the Greater Dusseldorf area correspond to the relevant medicolegal literature. Our results included exclusively young to middle-aged, usually single men who were found dead in their city apartments. Clothing and devices used showed a great variety. Women's or fetish clothing and complex shackling or hanging devices were disproportionately frequent. In most cases, death occurred due to hanging or ligature strangulation. There was no increased incidence of underlying psychiatric disorders. In most of the deceased no or at least no remarkable alcohol intoxication was found. Occasionally, it may be difficult to reliably differentiate autoerotic accidents, accidents occurring in connection with practices of bondage & discipline, dominance & submission (BDSM) from natural death, suicide or homicide.

    The nationwide "German Health Interview and Examination Survey for Children and Adolescents" (KiGGS), conducted in 2003-2006, showed an increase in the prevalence rates of overweight and obesity compared to the early 1990s, indicating the need for regularly monitoring. Recently, a follow-up-KiGGS Wave 1 (2009-2012)-was carried out as a telephone-based survey, providing self-reported height and weight. Since self-reports lead to a bias in prevalence rates of weight status, a correction is needed. The aim of the present study is to obtain updated prevalence rates for overweight and obesity for 11- to 17-year olds living in Germany after correction for bias in self-reports. In KiGGS Wave 1, self-reported height and weight were collected from 4948 adolescents during a telephone interview. Participants were also asked about their body perception. From a subsample of KiGGS Wave 1 participants, measurements for height and weight were collected in a physical examination. In order to correct prevalence rates derived from self-reports, weight status categories based on self-reported and measured height and weight were used to estimate a correction formula according to an established procedure under consideration of body perception. The correction procedure was applied and corrected rates were estimated. The corrected prevalence of overweight, including obesity, derived from KiGGS Wave 1, showed that the rate has not further increased compared to the KiGGS baseline survey (18.9 % vs. 18.8 % based on the German reference). The rates of overweight still remain at a high level. The results of KiGGS Wave 1 emphasise the significance of this health issue and the need for prevention of overweight and obesity in children and adolescents.

    The aim of this study was to look for temporal changes in the prevalence of diabetes and cardiometabolic risk factors in two residential colonies in Chennai. Chennai Urban Population Study (CUPS) was carried out between 1996-1998 in Chennai in two residential colonies representing the middle income group (MIG) and lower income group (LIG), respectively. The MIG had twice the prevalence rate of diabetes as the LIG and higher prevalence rates of hypertension, obesity, and dyslipidemia. They were motivated to increase their physical activity, which led to the building of a park. The LIG was given standard lifestyle advice. Follow-up surveys of both colonies were performed after a period of 10 years. In the MIG, the prevalence of diabetes increased from 12.4 to 15.4% (24% increase), while in the LIG, it increased from 6.5 to 15.3% (135% increase, p India with a convergence of prevalence rates among people in the MIG and LIG. This could have a serious economic impact on poor people in developing countries such as India. © 2011 Diabetes Technology Society.

    Full Text Available Objectives: The current study was performed to establish the prevalence rate of hearing disorders in school age children. Method: This study has been performed in a randomized manner among 1000 school-age children (500 girls and 500 boys in the years between1976-1997 in Behbehan. All subjects underwent Audiometric evaluations, Otoscopy, and impedance audiometry. Additionally, parents, children and teachers were interviewed or asked by questionnaires regarding the familial status of parents, familial history of any hearing loss and the awareness of suffering hearing loss. The findings have been prepared in the charts and tables and the relationship between age and gender of the subjects with the incidence of hearing loss has been evaluated via the statistical test X² and hearing loss in left and right ear was compared by T-test. Results: the findings demonstrated that 6.6% of the subjects suffered hearing loss in one ear (2.2% or both ears (4.3%. 4.8% of the patients suffered conductive hearing loss while 1.6% suffered sensory-neural hearing loss. In .2% patients complained different types of hearing loss in the ears. Hearing loss was mostly slight and the relationship between age and gender with the incidence of hearing loss was not statistically significant. Conclusion: Based on the findings we have concluded that in18.4% of the subjects, medical treatment was required and 0.7% of them were in need of rehabilitation. The percentage of the awareness of the hearing disorders among children, parents and teachers was 21.2%, 22.7% and 15.2% respectively.

    Differences in cystatin C and creatinine-based estimated glomerular filtration rate (eGFR) can lead to clinical uncertainty. Existing eGFR equations perform poorly in a subset of individuals. This study aims to describe the prevalence of differences between cystatin C-based (eGFR cys ) and creatinine-based (eGFR creat ) eGFR in older adults and to explore which subsets of individuals may be most affected by differing estimations. In this cross-sectional study, participants from a cohort of community-dwelling older adults were examined at a baseline visit in 2001-2004 as part of the larger "Good Aging in Skåne" study. Exposure variables were obtained from questionnaires, interviews, examinations, and medical records. Blood samples were taken during the baseline visit, cryopreserved, and analyzed at a later time for biomarkers. The CKD-EPI equations were used to estimate GFR. Initial descriptive analyses were performed on 2931 individuals. A total of 2532 participants were included in the final multiple linear regression. Nearly two-thirds of participants had eGFR differences exceeding 10%, with nearly 20 % of participants having eGFR differences exceeding 30%. Smoking, age, body mass index (BMI), C-reactive protein (CRP), glucocorticoid use, and mean eGFR were correlated with differences between eGFR creat and eGFR cys . Differences between eGFR creat and eGFR cys are common and often of large magnitude in this community-dwelling population of older adults. The finding of multiple non-GFR determinants correlated to differences in GFR estimations can help direct future research to improve eGFR equations for subgroups prone to conflicting GFR estimations or to guide choice of biomarker for GFR estimation in these subgroups.

    An outline of the Greater Vancouver Regional District (GVRD) waste-to-energy program was presented. The GVRD has an annual budget for solid waste management of $90 million. Energy recovery revenues from solid waste currently exceed $10 million. Over 1,660,00 tonnes of GVRD waste is recycled, and another 280,000 tonnes is converted from waste to energy. The GVRD waste-to-energy facility combines state-of-the-art combustion and air pollution control, and has processed over 5 million tonnes of municipal solid waste since it opened in 1988. Its central location minimizes haul distance, and it was originally sited to utilize steam through sales to a recycle paper mill. The facility has won several awards, including the Solid Waste Association of North America award for best facility in 1990. The facility focuses on continual improvement, and has installed a carbon injection system; an ammonia injection system; a flyash stabilization system; and heat capacity upgrades in addition to conducting continuous waste composition studies. Continuous air emissions monitoring is also conducted at the plant, which produces a very small percentage of the total air emissions in metropolitan Vancouver. The GVRD is now seeking options for the management of a further 500,000 tonnes per year of solid waste, and has received 23 submissions from a range of waste energy technologies which are now being evaluated. It was concluded that waste-to-energy plants can be located in densely populated metropolitan areas and provide a local disposal solution as well as a source of renewable energy. Other GVRD waste reduction policies were also reviewed. refs., tabs., figs.

  16. Food allergy: is prevalence increasing?

    2017-03-01

    It is generally accepted that the prevalence of food allergy has been increasing in recent decades, particularly in westernised countries, yet high-quality evidence that is based on challenge confirmed diagnosis of food allergy to support this assumption is lacking because of the high cost and potential risks associated with conducting food challenges in large populations. Accepting this caveat, the use of surrogate markers for diagnosis of food allergy (such as nationwide data on hospital admissions for food anaphylaxis or clinical history in combination with allergen-specific IgE (sIgE) measurement in population-based cohorts) has provided consistent evidence for increasing prevalence of food allergy at least in western countries, such as the UK, United States and Australia. Recent reports that children of East Asian or African ethnicity who are raised in a western environment (Australia and United States respectively) have an increased risk of developing food allergy compared with resident Caucasian children suggest that food allergy might also increase across Asian and African countries as their economies grow and populations adopt a more westernised lifestyle. Given that many cases of food allergy persist, mathematical principles would predict a continued increase in food allergy prevalence in the short to medium term until such time as an effective treatment is identified to allow the rate of disease resolution to be equal to or greater than the rate of new cases. © 2017 Royal Australasian College of Physicians.

    To determine the prevalence of hypermetabolism, relative to body composition, in amyotrophic lateral sclerosis (ALS) and its relationship with clinical features of disease and survival. Fifty-eight patients with clinically definite or probable ALS as defined by El Escorial criteria, and 58 age and sex-matched control participants underwent assessment of energy expenditure. Our primary outcome was the prevalence of hypermetabolism in cases and controls. Longitudinal changes in clinical parameters between hypermetabolic and normometabolic patients with ALS were determined for up to 12 months following metabolic assessment. Survival was monitored over a 30-month period following metabolic assessment. Hypermetabolism was more prevalent in patients with ALS than controls (41% vs 12%, adjusted OR=5.4; pALS. Mean lower motor neuron score (SD) was greater in hypermetabolic patients when compared with normometabolic patients (4 (0.3) vs 3 (0.7); p=0.04). In the 12 months following metabolic assessment, there was a greater change in Revised ALS Functional Rating Scale score in hypermetabolic patients when compared with normometabolic patients (-0.68 points/month vs -0.39 points/month; p=0.01). Hypermetabolism was inversely associated with survival. Overall, hypermetabolism increased the risk of death during follow-up to 220% (HR 3.2, 95% CI 1.1 to 9.4, p=0.03). Hypermetabolic patients with ALS have a greater level of lower motor neuron involvement, faster rate of functional decline and shorter survival. The metabolic index could be important for informing prognosis in ALS. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

    Full Text Available Introduction: Within Canada, injuries are the leading cause of death amongst children fourteen years of age and younger, and also one of the leading causes of morbidity. Low Socio Economic Status (SES seems to be a strong indicator of a higher prevalence of injuries. This study aims to identify hotspots for pediatric Traumatic Brain Injury (TBI and examines the relationship between SES and pediatric TBI rates in greater Vancouver, British Columbia (BC, Canada. Methods: Pediatric TBI data from the BC Trauma Registry (BCTR was used to identify all pediatric TBI patients admitted to BC hospitals between the years 2000 and 2013. Spatial analysis was used to identify hotspots for pediatric TBI. Multivariate analysis was used to distinguish census variables that were correlated with rates of injury. Results: Six hundred and fifty three severe pediatric TBI injuries occurred within the BC Lower Mainland between 2000 and 2013. High rates of injury were concentrated in the East, while low rate clusters were most common in the West of the region (more affluent neighborhoods. A low level of education was the main predictor of a high rate of injury (OR = 1.13, 95% CI = 1.03–1.23, p-Value 0.009. Conclusion: While there was a clear relationship between different SES indicators and pediatric TBI rates in greater Vancouver, income-based SES indicators did not serve as good predictors within this region.

    Full Text Available This study aims to identify any differences regarding gender, age, socioeconomic status (SES, self-rated health, perceived stress and the purchase of prescribed drugs among people who practice mind and body exercises (MBE extensively compared to people who do not.The study includes 3,913 men and 4,803 women aged 20-72 who participated in the Swedish Longitudinal Occupational Survey of Health (SLOSH. The respondents were divided into three groups depending on frequency of MBE practice (never/seldom/often. Measures regarding MBE practice, health behaviors, self-rated health, and illnesses were drawn from the SLOSH questionnaire, while more objective measures of socioeconomic status and education were derived from registry data. In addition, data on purchases of prescription drugs for all respondents were included in the study. These data were obtained from the Swedish Prescribed Drug Register, which contains information about prescription drugs dispensed at Swedish pharmacies. Separate analyses were performed for mental MBE (mindfulness, meditation, relaxation techniques and physical MBE (yoga, Tai Chi, Qi Gong, respectively.A high intensity MBE practice is cross-sectionally related to poor self-assessed health (sleeping problems, pain, depressive symptoms, mental disorders, high levels of stress, and high levels of purchases of psychotropic drugs and analgesics. These cross-sectional relationships are generally stronger for mental MBE than for bodily-directed MBE. More women than men are practicing MBE on a regular basis, and physically active people participate to a greater extent in MBE compared with the physically inactive.Overall, the study shows that frequent participation in mind and body exercises is associated with high levels of purchases of psychotropic drugs and analgesics as well as with poor self-assessed health and high levels of stress. However, since this is a cross-sectional study, it is impossible to establish cause and effect

    2011-01-01

    Recent research on Greater Sage-Grouse (Centrocercus urophasianus) genetics has revealed some important findings. First, multiple paternity in broods is more prevalent than previously thought, and leks do not comprise kin groups. Second, the Greater Sage-Grouse is genetically distinct from the congeneric Gunnison sage-grouse (C. minimus). Third, the Lyon-Mono population in the Mono Basin, spanning the border between Nevada and California, has unique genetic characteristics. Fourth, the previous delineation of western (C. u. phaios) and eastern Greater Sage-Grouse (C. u. urophasianus) is not supported genetically. Fifth, two isolated populations in Washington show indications that genetic diversity has been lost due to population declines and isolation. This chapter examines the use of molecular genetics to understand the biology of Greater Sage-Grouse for the conservation and management of this species and put it into the context of avian ecology based on selected molecular studies.

    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.

    Reducing the amount of fuel that people use for personal driving saves money, improves local air quality, and reduces personal contributions to climate change. This handbook was developed to be used as a tool for a fuel efficient driving pilot program in Greater Sudbury in 2009-2010. Specifically, the purpose of the handbook was to provide greater Sudbury drivers with information on how to drive and maintain their personal vehicles in order to maximize fuel efficiency. The handbook also provides tips for purchasing fuel efficient vehicles. It outlines the benefits of fuel maximization, with particular reference to reducing contributions to climate change; reducing emissions of air pollutants; safe driving; and money savings. Some tips for efficient driving are to avoid aggressive driving; use cruise control; plan trips; and remove excess weight. Tips for efficient winter driving are to avoid idling to warm up the engine; use a block heater; remove snow and ice; use snow tires; and check tire pressure. The importance of car maintenance and tire pressure was emphasized. The handbook also explains how fuel consumption ratings are developed by vehicle manufacturers. refs., figs.

  5. Women at greater risk of HIV infection.

    Although many people believe that mainly men get infected with HIV/AIDS, women are actually getting infected at a faster rate than men, especially in developing countries, and suffer more from the adverse impact of AIDS. As of mid-1996, the Joint UN Program on AIDS estimated that more than 10 million of the 25 million adults infected with HIV since the beginning of the epidemic are women. The proportion of HIV-positive women is growing, with almost half of the 7500 new infections daily occurring among women. 90% of HIV-positive women live in a developing country. In Asia-Pacific, 1.4 million women have been infected with HIV out of an estimated total 3.08 million adults from the late 1970s until late 1994. Biologically, women are more vulnerable than men to infection because of the greater mucus area exposed to HIV during penile penetration. Women under age 17 years are at even greater risk because they have an underdeveloped cervix and low vaginal mucus production. Concurrent sexually transmitted diseases increase the risk of HIV transmission. Women's risk is also related to their exposure to gender inequalities in society. The social and economic pressures of poverty exacerbate women's risk. Prevention programs are discussed.

    We examined the gender-difference effect on abnormal spontaneous neuronal activity of male and female major depressive disorder (MDD) patients using the amplitude of low-frequency fluctuation (ALFF) and the further clarified the relationship between the abnormal ALFF and differences in MDD prevalence rates between male and female patients. Fourteen male MDD patients, 13 female MDD patients and 15 male and 15 female well matched healthy controls (HCs) completed this study. The ALFF approach was used, and Pearson correlation was conducted to observe a possible clinical relevance. There were widespread differences in ALFF values between female and male MDD patients, including some important parts of the frontoparietal network, auditory network, attention network and cerebellum network. In female MDD patients, there was a positive correlation between average ALFF values of the left postcentral gyrus and the severity of weight loss symptom. The gender-difference effect leading to abnormal brain activity is an important underlying pathomechanism for different somatic symptoms in MDD patients of different genders and is likely suggestive of higher MDD prevalence rates in females. The abnormal ALFF resulting from the gender-difference effect might improve our understanding of the differences in prevalence rates between male and female MDD patients from another perspective.

    Background While it is recognised that depression is prevalent in Rheumatoid Arthritis (RA), recent studies have also highlighted significant levels of anxiety in RA patients. This study compared two commonly used scales, the Depression Anxiety and Stress Scale (DASS) and the Hospital Anxiety and Depression Scale (HADS), in relation to their measurement range and cut points to consider the relative prevalence of both constructs, and if prevalence rates may be due to scale-specific case definition. Methods Patients meeting the criteria for RA were recruited in Leeds, UK and Sydney, Australia and asked to complete a survey that included both scales. The data was analysed using the Rasch measurement model. Results A total of 169 RA patients were assessed, with a repeat subsample, resulting in 323 cases for analysis. Both scales met Rasch model expectations. Using the 'possible+probable' cut point from the HADS, 58.3% had neither anxiety nor depression; 13.5% had anxiety only; 6.4% depression only and 21.8% had both 'possible+probable' anxiety and depression. Cut points for depression were comparable across the two scales while a lower cut point for anxiety in the DASS was required to equate prevalence. Conclusions This study provides further support for high prevalence of depression and anxiety in RA. It also shows that while these two scales provide a good indication of possible depression and anxiety, the estimates of prevalence so derived could vary, particularly for anxiety. These findings are discussed in terms of comparisons across studies and selection of scales for clinical use. PMID:22269280

    The productivity of countries around the globe is adversely affected by the health-related problems of their labour force. This study examined the effect of the prevalence of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and life expectancy on the economic growth of 33 Sub-Saharan African (SSA) countries over a period of 11 years (2002-2012). The study employed a dynamic panel approach as opposed to the static traditional approach utilised in the literature. The dynamic approach became eminent because of the fact that HIV/AIDS is a dynamic variable as its prevalence today depends on the previous years. The result revealed that HIV/AIDS is negatively correlated with economic growth in the region, with a coefficient of 0.014, and significant at the 1% level. That is, a 10% increase in HIV/AIDS prevalence leads to a 0.14% decrease in the GDP of the region. Tackling HIV/AIDS is therefore imperative to the developing Sub-Saharan African region and all hands must be on deck to end the menace globally.

    Aim: To assess the prevalence and the department's detection rate of adrenocortical hyperplasia. Materials and methods: All computed tomography (CT) examinations of the adrenal glands between February and April 2011 were reviewed. The study excluded patients with known underlying cancer, abdominal trauma, or endocrine disease. The adrenal gland was deemed enlarged if its body was greater than 10 mm diameter, or a limb greater than 5 mm. Results: There were a total of 564 eligible CT studies during this period. A total of 64 cases of incidental adrenal enlargement were found giving a prevalence of 11.3%. Only nine cases were reported in the contemporaneous CT report. Conclusion: The results of the present study show that incidental adrenal enlargement has a significant prevalence. It is often dismissed during reporting, and awareness needs to be raised in the radiological community. Equally, the clinical and biochemical significance needs to be assessed with endocrine correlation

    Objective Pediatric bipolar disorder (PBD) is associated with poor outcomes, including suicidal ideation (SI) and suicide attempt (SA). However, frequencies and risk factors of SI/SA and targeted intervention trials for SI/SA in PBD have not been reviewed systematically. Methods We conducted a systematic PubMed review, searching for articles reporting on prevalences/incidences, correlates and intervention studies targeting SI/SA in PBD. Weighted means were calculated, followed by an exploratory meta-regression of SI and SA correlates. Results Fourteen studies (n = 1,595) with 52.1% males aged 14.4 years reported data on SI/SA prevalence (N = 13, n = 1,508) and/or correlates (N = 10, n = 1,348) in PBD. Weighted mean prevalences were: past SI = 57.4%, past SA = 21.3%, current SI = 50.4%, and current SA = 25.5%; incidences (mean: 42 months follow-up were: SI = 14.6% and SA = 14.7%. Regarding significant correlates, SI (N = 3) was associated with a higher percentage of Caucasian race, narrow (as opposed to broad) PBD phenotype, younger age, and higher quality of life than SA. Significant correlates of SA (N = 10) included female gender, older age, earlier illness onset, more severe/episodic PBD, mixed episodes, comorbid disorders, past self-injurious behavior/SI/SA, physical/sexual abuse, parental depression, family history of suicidality, and poor family functioning. Race, socioeconomic status, living situation, and life events were not clearly associated with SA. In a meta-regression analysis, bipolar I disorder and comorbid attention-deficit hyperactivity disorder were significantly associated with SA. Only one open label study targeting the reduction of SI/SA in PBD was identified. Conclusions SI and SA are highly common but under-investigated in PBD. Exploration of predictors and protective factors is imperative for the establishment of effective preventive and intervention strategies, which are urgently needed. PMID:23829436

  15. Does the prevalence of latent toxoplasmosis and frequency of Rhesus-negative subjects correlate with the nationwide rate of traffic accidents?

    Latent toxoplasmosis is probably the most common protistan parasitic disease with many indirect negative impacts on human health. One of the important impacts is impaired psychomotor function leading to reduced driving efficiency in Toxoplasma-seropositive subjects. Numerous case-control studies have established a positive relation between the seroprevalence of Toxoplasma gondii (Nicolle et Manceaux, 1908) and probability of traffic accidents in study populations. The prevalence of toxoplasmosis varies between populations according to local geographical conditions, hygienic practices and kitchen habits. Similarly, we see a striking variation in the incidence of traffic accidents across countries. Hence, we compiled the largest ever data set on the seroprevalence of toxoplasmosis and tried to understand its role in traffic accident-related deaths and disabilities across 87 countries. Simple non-parametric analysis showed a positive and strong relation of T. gondii seroprevalence and traffic accident related disabilities. Further, we conducted multivariate analysis to control for confounding factors. After controlling for wealth, geographical latitude, health of population, length of roads and number of vehicles, the correlation disappeared. When the frequency of RhD negativity and its interaction with toxoplasmosis were included into the model, the effects of toxoplasmosis seemingly returned. However, the analysed data suffered from the problem of multicollinearity. When a proper method of analysis, ridge regression, was applied, the effects of toxoplasmosis prevalence and RhD negativity frequency disappeared again. The existence of a strong correlation between the prevalence of toxoplasmosis and health of population in particular countries, which was the probable cause of multicollinearity and possible reason for the negative result of the present study, suggests that 'asymptomatic' latent toxoplasmosis could have a large impact on public health.

    To establish the prevalence of foot ulceration in patients with rheumatoid arthritis (RA) in secondary care. A postal survey of all patients with RA (n = 1,130) under the care of rheumatologists in Bradford, West Yorkshire, UK was performed. The prevalence data were validated through clinical examination, case-note review, and contact with health professionals. The false-negative rate was investigated in a subsample of patients (n = 70) who denied any history of ulceration. The postal survey achieved a 78% response rate. Following validation, the point prevalence of foot ulceration was 3.39% and the overall prevalence was 9.73%. The false-positive rate was initially high at 21.21%, but use of diagrammatic questionnaire data to exclude leg ulceration reduced the rate to 10.76%. The false-negative rate was 11.76%. The most common sites for ulceration were the dorsal aspect of hammer toes, the metatarsal heads, and the metatarsophalangeal joint in patients with hallux abducto valgus, with 33% of patients reporting multiple sites of ulceration. Patients with open-foot and healed-foot ulceration had significantly longer RA disease duration, reported significantly greater use of special footwear, and had a higher prevalence of foot surgery than ulcer-free patients. Foot ulceration affects a significant proportion of patients with RA. Further work is needed to establish risk factors for foot ulceration in RA and to target foot health provision more effectively.

No período de setembro de 2000 a fevereiro de 2001, por meio de amostragem domiciliar por conveniência, foram examinadas 265 amostras fecais da população pelo método de sedimentação espontânea, das quais 57% foram positivas para enteroparasitos. Entamoeba coli (35,8%, Endolimax nana (13,6%, Hymenolepis nana (9,4% e os ancilostomídeos (9,4% foram os parasitos mais freqüentes. Foram observados dois casos de A. lumbricoides, possivelmente adquiridos fora do município. Nenhuma amostra foi positiva para T. trichiura. Esses resultados mostram um padrão diferente do restante do país. Traça-se um paralelo entre os resultados deste estudo com os achados paleoparasitológicos na população pré-histórica, habitante da região há pelo menos sete mil anos.We report on intestinal parasite infection prevalence in a population sample from São Raimundo Nonato, Southeast Piauí State, Brazil, aimed at comparison with previous studies on Trichuris trichiura and Ascaris lumbricoides infection. A total of 265 stool specimens were collected and examined by spontaneous sedimentation. Approximately 57% of specimens were infected with at least one parasite species. Entamoeba coli (35.8%, Endolimax nana (13.6%, Hymenolepis nana (9.4%, and hookworm (9.4% were the most frequently observed parasites. Two cases of roundworm infection were detected, probably acquired outside the region. T. trichiura eggs were not found. Interestingly, neither A. lumbricoides nor T. trichiura has been found in local prehistoric human coprolites. Nevertheless, hookworm infection has been present in the region for at least 7,000 years.

    Tick-borne spotted fever group (SFG) rickettsioses are emerging infectious diseases in Sub-Saharan Africa. In Madagascar, the endemicity of tick-borne rickettsiae and their vectors has been incompletely studied. The first part of the present study was conducted in 2011 and 2012 to identify potential anthropophilic tick vectors for SFG rickettsiae on cattle from seven Malagasy regions, and to detect and characterize rickettsiae in these ticks. Amblyomma variegatum was the only anthropophilic tick species found on 262 cattle. Using a novel ompB-specific qPCR, screening for rickettsial DNA was performed on 111 A. variegatum ticks. Rickettsial DNA was detected in 96 of 111 ticks studied (86.5%). Rickettsia africae was identified as the only infecting rickettsia using phylogenetic analysis of ompA and ompB gene sequences and three variable intergenic spacers from 11 ticks. The second part of the study was a cross-sectional survey for antibodies against SFG rickettsiae in plasma samples taken from healthy, pregnant women at six locations in Madagascar, two at sea level and four between 450 and 1300m altitude. An indirect fluorescent antibody test with Rickettsia conorii as surrogate SFG rickettsial antigen was used. We found R. conorii-seropositives at all altitudes with prevalences between 0.5% and 3.1%. Our results suggest that A. variegatum ticks highly infected with R. africae are the most prevalent cattle-associated tick vectors for SFG rickettsiosis in Madagascar. Transmission of SFG rickettsiosis to humans occurs at different altitudes in Madagascar and should be considered as a relevant cause of febrile diseases. Copyright © 2015 Elsevier GmbH.

    Women protective service workers die by suicide at a higher rate than women workers in other occupational groups. However, no study has examined rates and correlates of suicidal thoughts and behaviors among women firefighters, despite the potential for these data to inform suicide screening, prevention, and intervention initiatives. The purpose of this study is to describe and compare pre-career and career rates of suicidal thoughts and behaviors and identify their sociodemographic and occupational correlates among women firefighters. Data were obtained from 313 current U.S. women firefighters who completed a web-based survey (mean age = 37.30y, SD = 9.70y, 92.7% White). Pre-career rates of suicide ideation, plans, attempts, and non-suicidal self-injury (NSSI) were found to be 28.4%, 10.2%, 5.8%, and 11.2%, respectively. Career rates of suicide ideation, plans, attempts, and NSSI were found to be 37.7%, 10.9%, 3.5%, and 9.3%, respectively. Pre-career rates of suicide ideation (OR = 4.760, 95% CI = 2.820-8.034, p harassment) are needed. Copyright © 2017 Elsevier B.V. All rights reserved.

    To analyse gender differences in the relationship of individual social class, employment status and neighbourhood unemployment rate with present type 2 diabetes mellitus (T2DM). Five cross-sectional studies. Studies were conducted in five regions of Germany from 1997 to 2006. The sample consisted of 8871 individuals residing in 226 neighbourhoods from five urban regions. Prevalent T2DM. We found significant multiplicative interactions between gender and the individual variables--social class and employment status. Social class was statistically significantly associated with T2DM in men and women, whereby this association was stronger in women (lower vs higher social class: OR 2.68 (95% CIs 1.66 to 4.34)) than men (lower vs higher social class: OR 1.78 (95% CI 1.22 to 2.58)). Significant associations of employment status and T2DM were only found in women (unemployed vs employed: OR 1.73 (95% CI 1.02 to 2.92); retired vs employed: OR 1.77 (95% CI 1.10 to 2.84); others vs employed: OR 1.64 (95% CI 1.01 to 2.67)). Neighbourhood unemployment rate was associated with T2DM in men (high vs low tertile: OR 1.52 (95% CI 1.18 to 1.96)). Between-study and between-neighbourhood variations in T2DM prevalence were more pronounced in women. The considered covariates helped to explain statistically the variation in T2DM prevalence among men, but not among women. Social class was inversely associated with T2DM in both men and women, whereby the association was more pronounced in women. Employment status only affected T2DM in women. Neighbourhood unemployment rate is an important predictor of T2DM in men, but not in women.

  2. Greater learnability is not sufficient to produce cultural universals.

    Rafferty, Anna N; Griffiths, Thomas L; Ettlinger, Marc

    2013-10-01

    Looking across human societies reveals regularities in the languages that people speak and the concepts that they use. One explanation that has been proposed for these "cultural universals" is differences in the ease with which people learn particular languages and concepts. A difference in learnability means that languages and concepts possessing a particular property are more likely to be accurately transmitted from one generation of learners to the next. Intuitively, this difference could allow languages and concepts that are more learnable to become more prevalent after multiple generations of cultural transmission. If this is the case, the prevalence of languages and concepts with particular properties can be explained simply by demonstrating empirically that they are more learnable. We evaluate this argument using mathematical analysis and behavioral experiments. Specifically, we provide two counter-examples that show how greater learnability need not result in a property becoming prevalent. First, more learnable languages and concepts can nonetheless be less likely to be produced spontaneously as a result of transmission failures. We simulated cultural transmission in the laboratory to show that this can occur for memory of distinctive items: these items are more likely to be remembered, but not generated spontaneously once they have been forgotten. Second, when there are many languages or concepts that lack the more learnable property, sheer numbers can swamp the benefit produced by greater learnability. We demonstrate this using a second series of experiments involving artificial language learning. Both of these counter-examples show that simply finding a learnability bias experimentally is not sufficient to explain why a particular property is prevalent in the languages or concepts used in human societies: explanations for cultural universals based on cultural transmission need to consider the full set of hypotheses a learner could entertain and all of

    The 2008 World Health Organization (WHO) criteria were used to identify 88 consecutive Mayo Clinic patients with 'myelodysplastic syndrome with isolated del(5q)' (median age 74 years; 60 females). In all, 60 (68%) patients were followed up to the time of their death. Overall median survival was 66 months; leukemic transformation was documented in five (5.7%) cases. Multivariable analysis identified age >or=70 years (P=0.01), transfusion need at diagnosis (P=0.04) and dysgranulopoiesis (P=0.02) as independent predictors of shortened survival; the presence of zero (low risk), one (intermediate risk) or >or=2 (high risk) risk factors corresponded to median survivals of 102, 52 and 27 months, respectively. Janus kinase 2 (JAK2), thrombopoietin receptor (MPL), isocitrate dehydrogenase 1 (IDH1) and IDH2 mutational analysis was performed on archived bone marrows in 78 patients; JAK2V617F and MPLW515L mutations were shown in five (6.4%) and three (3.8%) patients, respectively, and did not seem to affect phenotype or prognosis. IDH mutations were not detected. Survival was not affected by serum ferritin and there were no instances of death directly related to iron overload. The current study is unique in its strict adherence to WHO criteria for selecting study patients and providing information on long-term survival, practical prognostic factors, baseline risk of leukemic transformation and the prevalence of JAK2, MPL and IDH mutations.

    2014-12-01

    Determining the relationship between gun ownership levels and firearm homicide rates is critical to inform public health policy. Previous research has shown that state-level gun ownership, as measured by a widely used proxy, is positively associated with firearm homicide rates. A newly developed proxy measure that incorporates the hunting license rate in addition to the proportion of firearm suicides correlates more highly with state-level gun ownership. To corroborate previous research, we used this new proxy to estimate the association of state-level gun ownership with total, firearm, and non-firearm homicides. Using state-specific data for the years 1981-2010, we modelled these rates as a function of gun ownership level, controlling for potential confounding factors. We used a negative binomial regression model and accounted for clustering of observations among states. We found that state-level gun ownership as measured by the new proxy, is significantly associated with firearm and total homicides but not with non-firearm homicides.

    Full Text Available Self-rated health is a major health indicator and has been widely used in epidemiologic surveys. Current study analyzes the factors associated to regular and negative self-rated health in Brazilian college students. Current investigation is a segment of the 2010 MONISA study carried out in a Brazilian public university with 5,461 students. Estimated sample comprised 1,232 university students and results showed self-rated regular and negative health. Multinomial logistic regression estimated Odds Ratio (OR. The factors associated to regular health self-evaluation negative assessment of relationship with professors (OR: 1.85; CI95%: 1.20-2.87; inactivity in leisure (OR: 2.34; CI95%: 1.73-3.16; insufficient consumption of vegetables; almost daily consumption of soft drinks; assessment of intermediate and negative stress (OR: 3.34; CI95%: 2.11-5.28. Students inactive in leisure (OR: 2.37; 95%CI: 1.09-5.13, students with self-evaluated negative stress (OR: 10.1; 95%CI: 3.23-31.8 and obese students (OR: 4.52; 95%CI: 1.36-15.0 were associated to the negative health self-assessment. It has been verified that health behavior is rather associated to the regular self-assessment of health, whereas perceptive and biological indicators were more associated to negative health self-assessment.

    Binge eating disorder (BED) was recently included in the DSM-5. The prevalence rate for BED using the DSM-IV-TR research criteria tends to be higher in bariatric surgery candidates than the normative population; however, no studies have examined how many more bariatric surgery candidates will meet the new, less conservative criteria of DSM-5. We explore the current BED prevalence rate change in a sample of bariatric surgery candidates. Data were obtained for 1,283 bariatric surgery candidates. 84 men and 213 women were diagnosed with current BED using DSM-IV-TR research criteria. A semi-structured interview, the binge eating scale (BES), and a Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) were given to every patient as part of standard procedures mandated by the facility. An additional 3.43% (p MMPI-2-RF and BES scores when compared with patients who met DSM-IV-TR criteria for BED. Thus, the current investigation indicates that individuals meeting BED criteria based on DSM-5 are similar to those meeting the more conservative diagnostic threshold outlined in DSM-IV-TR in a sample of bariatric surgery candidates. © 2014 Wiley Periodicals, Inc.

    Burnout is a job-related psychological syndrome with three aspects: emotional exhaustion, depersonalization, and perceived lack of personal accomplishment. Burnout is associated with deleterious effects on both workers and their work. When burnout affects physicians, their well-being, longevity, and care of patients are at risk. Recent studies concerning physician burnout treat specialists such as radiologists as one group. We studied burnout in musculoskeletal (MSK) subspecialist radiologists. An institutional review board exemption was obtained. Society of Skeletal Radiology members received invitations to an anonymous survey that included questions from the Maslach Burnout Inventory trademark (MBI) measuring all three aspects of burnout. The response rate was 36.4% (433/1190). The prevalence of emotional exhaustion was 61.7% (255/413), of depersonalization 53.3% (219/411), and of perceived lack of personal accomplishment 39.6% (161/407). Only 19.5% (79/405) of MSK radiologists reported no burnout, while 80.5% (326/405) reported burnout along one or more dimensions. For all three dimensions, the prevalence was higher and the mean severity was worse for private practice compared with academic practice. The prevalence of burnout was affected more by practice setting than by gender. Burnout prevalence and severity also varied systematically with years since completion of training. Among MSK radiologists, we found a much higher prevalence and greater severity of burnout than has been previously reported for radiologists and other physicians. There were differences in prevalence and severity of burnout among practice settings, genders, and longevity cohorts. (orig.)

    Maternal depression is a substantial problem that has negative consequences on the health of both mother and child. Little research has been done on the prevalence of maternal depression in the developing world. This study aims to estimate the prevalence of current depression among mothers in Honduras and identify demographic predictors of depression in this sample. A modified Spanish version of the PHQ-9 and a demographic questionnaire were administered by trained interviewers to 415 rural and urban women aged 15-66 who had children between 1 and 10 years old. Prevalence of current major depressive syndrome was 17.6%. Mild depressive symptoms were detected in 52% of the sample. The estimated prevalence of current major depressive syndrome in the urban sample (19%) was not significantly greater than in the rural sample (16%, p = 0.49). None of the demographic variables measured, including age, number of children, or marital status predicted major depression in this sample. Maternal depression occurred at a high rate in this sample of Honduran women. The estimated prevalence rates in this study are similar to rates of maternal depression in studies of mothers in other Latin American countries, as well as in samples of mothers on Medicaid in the United States. Further study is needed to confirm and extend these findings, and to identify predictors of maternal depression in this population.

    Full Text Available Abstract Background Staphylococcus aureus, particularly methicillin resistant (MRSA, is a common pathogen among patients receiving hemodialysis. To evaluate nasal carriage, molecular characterization and effectiveness of decolonization of MRSA among patients receiving hemodialysis in Taiwan, we conducted this study. Methods From January to June 2011, two nasal samplings with a 3-month interval were obtained from patients undergoing hemodialysis in a medical center (CGMH, and in a local hospital (YMH and sent for detection of MRSA. For MRSA carriers, decolonization procedures were administered. All patients in CGMH were observed if MRSA infections occurred during the study period. Results A total of 529 nasal specimens (265 from CGMH and 264 from YMH were collected from 296 patients (161 from CGMH and 135 from YMH. 233 patients participated in both surveys. Average one-time point MRSA carriage rate was 3.8%, and the rate was up to 6.9% for those with two-time point surveys. No additional significant factor for MRSA carriage was identified. Seventy percent of the 20 colonizing MRSA isolates, though categorized as healthcare-associated strains epidemiologically, shared common molecular characteristics of the local community-associated strains. Only one of the 20 MRSA-colonized patients failed decolonization and had persistent colonization, while without any intervention, 17 (61% of 28 patients with methicillin-sensitive S. aureus colonization in the first survey had persistent colonization of a genetically indistinguishable strain. Within the study period, two patients (1.24% in CGMH, one with MRSA colonization (9.1%, developed MRSA infection. Conclusion A substantial proportion of patients receiving hemodialysis in Taiwan had MRSA colonization, mostly genetically community strains. Decolonization procedures may effectively eliminate MRSA colonization and might reduce subsequent MRSA infection in these patients.

    The present study used data from an ongoing longitudinal study of the effects of maltreatment on adolescent development to (1) describe rates of maltreatment experiences obtained from retrospective self-report versus case record review for adolescents with child welfare–documented maltreatment histories, (2) examine self-reported versus child welfare–identified maltreatment in relation to mental health and risk behavior outcomes by maltreatment type, and (3) examine the association between the number of different types of maltreatment and mental health and risk behavior outcomes. Maltreatment was coded from case records using the Maltreatment Case Record Abstraction Instrument (MCRAI) and participants were asked at mean age = 18.49 about childhood maltreatment experiences using the Comprehensive Trauma Interview (CTI). Results showed that an average of 48% of maltreatment found by the MCRAI for each type of maltreatment were unique cases not captured by the CTI, whereas an average of 40% self-reported maltreatment (CTI) was not indicated by the MCRAI. Analyses with outcomes showed generally, self-reported maltreatment, regardless of concordance with MCRAI, was related to the poorest outcomes. The difference in associations with the outcomes indicates both self-report and case record review data may have utility depending on the outcomes being assessed. PMID:27777329

    Full Text Available A 48-year-old woman sustained simultaneous isolated bilateral greater trochanteric fracture, following a road traffic accident. The patient presented to us 1 month after the injury. She presented with complaints of pain in the left hip and inability to walk. Roentgenograms revealed displaced comminuted bilateral greater trochanter fractures. The fracture of the left greater trochanter was reduced and fixed internally using the tension band wiring technique. The greater trochanter fracture on the right side was asymptomatic and was managed conservatively. The patient regained full range of motion and use of her hips after a postoperative follow-up of 6 months. Isolated fractures of the greater trochanter are unusual injuries. Because of their relative rarity and the unsettled controversy regarding their etiology and pathogenesis, several methods of treatment have been advocated. Furthermore, the reports of this particular type of injury are not plentiful and the average textbook coverage afforded to this entity is limited. In our study we discuss the mechanism of injury and the various treatment options available.

    Objectives of this study were to determine prevalence of infection in feral cats in Northern Florida with a select group of infectious organisms and to determine risk factors for infection. Blood samples or sera from 553 cats were tested with a panel of antibody, antigen or PCR assays. Male cats were at higher risk for FIV, Mycoplasma haemofelis, and M. haemominutum. Infection with either FeLV or FIV was associated with increased risk for coinfection with the other retrovirus, M. haemofelis, or M. haemominutum. Bartonella henselae had the highest prevalence and was the only organism that did not have any associated risk for coinfection with other organisms. Feral cats in this study had similar or lower prevalence rates of infections than those published for pet cats in the United States. Thus, feral cats assessed in this study appear to be of no greater risk to human beings or other cats than pet cats.

    2010-02-01

    The present survey was performed to determine orthodontic treatment need in a large sample (n = 703) of 12-year-old schoolchildren from the southern part of Italy. The sample comprised 331 males (47 per cent) and 372 females (53 per cent), all orthodontically untreated. Two examiners, who had been previously trained in the use of occlusal indices, screened all the schoolchildren. The prevalence rates for the Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN) as well as for occlusal features (Angle Class, overjet, overbite, crowding, posterior crossbite) were calculated for the total sample. The IOTN grades were statistically compared in the two genders using the chi-square test. The findings indicated that this southern Italian school population showed a rather low prevalence rate for objective need for treatment (grades 4 and 5; 27.3 per cent of the total sample). This prevalence rate is generally lower than those reported in northern and central European countries (Sweden, Germany, and UK) but slightly greater than those in France. No significant differences in the DHC grades of the IOTN were found between genders. Among the occlusal features diagnosed in the subjects examined, a high prevalence rate was found for crowding (45.9 per cent). Moreover, posterior crossbites and Class III malocclusions, which would presumably have benefited from early orthodontic intervention, were still present in 14.2 and 4.3 per cent of the students, respectively.

    Proximal femoral fractures are frequently encountered in the emergency department (ED). Prompt diagnosis is paramount as delay will exacerbate the already poor outcomes associated with these injuries. In cases where radiography is negative but clinical suspicion remains high, magnetic resonance imaging (MRI) is the study of choice as it has the capability to depict fractures which are occult on other imaging modalities. Awareness of a particular subset of proximal femoral fractures, namely greater trochanteric fractures, is vital for both radiologists and clinicians since it has been well documented that they invariably have an intertrochanteric component which may require surgical management. The detection of intertrochanteric or cervical extension of greater trochanteric fractures has been described utilizing MRI but is underestimated with both computed tomography (CT) and bone scan. Therefore, if MRI is unavailable or contraindicated, the diagnosis of an isolated greater trochanteric fracture should be met with caution. The importance of avoiding this potential pitfall is demonstrated in the following case of an elderly woman with hip pain and CT demonstrating an isolated greater trochanteric fracture who subsequently returned to the ED with a displaced intertrochanteric fracture.

    Due to variation in estimates of the prevalence of internet addiction (IA) in prior research, we conducted two cross-sectional studies over two years and investigated the prevalence rate of IA in college students in Japan, and reconsidered appropriate cut-off points of self-rating scale to screen possible IA. This study is composed of two parts: survey I in 2014 and survey II in 2016, which were conducted in the same schools with an interval of two years. The study questionnaire included questions about demographics and internet use, and the Young's Internet Addiction Test (IAT). Additionally, the subjects in survey II were asked about self-reported IA. There were 1,005 respondents in total with a mean age of 18.9±1.3. The mean IAT scores remained stable between 2014 and 2016: 45.2±12.6 in survey I and 45.5±13.1 in survey II (overall mean IAT score of 45.4±13.0). With respect to self-reported IA in survey II, a total of 21.6% agreed (score of 5 or 6 on a 6-point Likert scale). We categorized these subjects as IA, and the remainder as non-IA. The mean IAT score showed significant difference between these two groups (57.8±14.3 vs 42.1±10.7, p<0.001). The severity of symptoms of IA among Japanese college students appears stable in recent years, with a mean IAT scores of over 40. Our results suggest that a screening score cut-off of 40 on the IAT could be reconsidered and that of 50 might be proposed for the cut-off. This article is protected by copyright.

    2015-01-01

    Background: Concerns that Internet gambling has elevated the prevalence of problem gambling have not been substantiated; however, evidence suggests a subgroup of Internet gamblers do experience higher rates of gambling harms. Greater overall involvement in gambling appears to be predictive of harms. The purpose of this study was to examine differences between Internet gamblers with a single or multiple online gambling accounts, including their gambling behaviours, factors influencing their online gambling and risk of experiencing gambling problems. Methods: Internet gamblers (3178) responding to an online survey that assessed their gambling behaviour, and use of single or multiple online gambling accounts. Results: Results revealed that multiple account holders were more involved gamblers, gambling on more activities and more frequently, and had higher rates of gambling problems than single account holders. Multiple account holders selected gambling sites based on price, betting options, payout rates and game experience, whereas single account holders prioritized legality and consumer protection features. Conclusion: Results suggest two different types of Internet gamblers: one motivated to move between sites to optimize preferred experiences with a tendency to gamble in a more volatile manner; and a smaller, but more stable group less influenced by promotions and experiences, and seeking a reputable and safe gambling experience. As the majority of Internet gamblers use multiple accounts, more universal responsible gambling strategies are needed to assist gamblers to track and control their expenditure to reduce risks of harm.

    Objectives: To estimate the prevalence of four types of childhood maltreatment in Denmark while taking into considerations how each of the types of maltreatment vary as a function of gender or child-protection status. Methods: Data were collected from a Danish national study conducted by The Danish National Centre for Social Research in 2008 and 2009. The study used a stratified random probability sample of young people aged 24 years. A sample of 4718 young adults were randomly selected by Statistics Denmark using the total birth cohort of all children born in 1984. The response rate was 63% leaving a total effective sample size of 2980. A structured residential or telephone interview enquired about a range of respondents maltreatment experiences. Results: Maltreatment is experienced by a significant proportion of Danish children. The reported prevalence rates were; physical neglect (3.0%), emotional abuse (5.2%), physical abuse (5.4%) and sexual abuse (3.4%). All trauma types were experienced by a greater percentage of females compared to males with the exception of physical abuse and all trauma types were experienced by a greater percentage of children given child-protection status. Conclusions: Female children and children who are given child protection status are those most at risk for experiencing maltreatment in Denmark. However, variability in prevalence rates of maltreatment across studies is problematic. Methodological variations and variation in abuse definitions may be partly attributable. PMID:24155769

    2017-12-01

    The aim of this study was to estimate uric acid renal stone prevalence rates of adults in different countries of the world. PubMed was searched for papers dealing with "urinary calculi and prevalence or composition" for the period from January 1996 to June 2016. Alternative searches were made to collect further information on specific topics. The prevalence rate of uric acid stones was computed by the general renal stone prevalence rate and the frequency of uric acid stones in each country. After the initial search, 2180 papers were extracted. Out of them, 79 papers were selected after the reading of the titles and of the abstracts. For ten countries, papers relating to both the renal stone prevalence in the general population and the frequency of uric stones were available. Additional search produced 13 papers that completed information on 11 more countries in 5 continents. Estimated prevalence rate of uric acid stones was >0.75% in Thailand, Pakistan, Saudi Arabia, Iran, South Africa (white population), United States and Australia; ranged 0.50-0.75% in Turkey, Israel, Italy, India (Southern), Spain, Taiwan, Germany, Brazil; and uric acid stone formation. A hot and dry climate increases fluid losses reducing urinary volume and urinary pH. A diet rich in meat protein causes low urinary pH and increased uric acid excretion. On the other hand, uric acid stone formation is frequently associated with obesity, metabolic syndrome and diabetes type 2 that are linked to dietary energy excess mainly from carbohydrate and saturated fat and also present with low urine pH values. An epidemic of uric acid stone formation could be if current nutritional trends will be maintained both in developed countries and in developing countries and the areas of greater climatic risk for the formation of uric acid stones will enlarge as result of the "global warming".

    Cable-grip systems are commonly used for greater trochanteric reattachment because they have provided the best fixation performance to date, even though they have a rather high complication rate. A novel reattachment system is proposed with the aim of improving fixation stability. It consists of a Y-shaped fixation plate combined with locking screws and superelastic cables to reduce cable loosening and limit greater trochanter movement. The novel system is compared with a commercially available reattachment system in terms of greater trochanter movement and cable tensions under different greater trochanteric abductor application angles. A factorial design of experiments was used including four independent variables: plate system, cable type, abductor application angle, and femur model. The test procedure included 50 cycles of simultaneous application of an abductor force on the greater trochanter and a hip force on the femoral head. The novel plate reduces the movements of a greater trochanter fragment within a single loading cycle up to 26%. Permanent degradation of the fixation (accumulated movement based on 50-cycle testing) is reduced up to 46%. The use of superelastic cables reduces tension loosening up to 24%. However this last improvement did not result in a significant reduction of the grater trochanter movement. The novel plate and cables present advantages over the commercially available greater trochanter reattachment system. The plate reduces movements generated by the hip abductor. The superelastic cables reduce cable loosening during cycling. Both of these positive effects could decrease the risks related to grater trochanter non-union. Copyright © 2012 IPEM.

    The Greater Sekhukhune-CAPABILITY Outreach Project was undertaken in a rural district in Limpopo, South Africa, as part of the European Union-funded CAPABILITY programme to investigate approaches for capacity building for the translation of genetic knowledge into care and prevention of congenital disorders. Based on previous experience of a clinical genetic outreach programme in Limpopo, it aimed to initiate a district clinical genetic service in Greater Sekhukhune to gain knowledge and experience to assist in the implementation and development of medical genetic services in South Africa. Implementing the service in Greater Sekhukhune was impeded by a developing staff shortage in the province and pressure on the health service from the existing HIV/AIDS and TB epidemics. This situation underscores the need for health needs assessment for developing services for the care and prevention of congenital disorders in middle- and low-income countries. However, these impediments stimulated the pioneering of innovate ways to offer medical genetic services in these circumstances, including tele-teaching of nurses and doctors, using cellular phones to enhance clinical care and adapting and assessing the clinical utility of a laboratory test, QF-PCR, for use in the local circumstances.

  11. Operational technology for greater confinement disposal

    1984-12-01

    Procedures and methods for the design and operation of a greater confinement disposal facility using large-diameter boreholes are discussed. It is assumed that the facility would be located at an operating low-level waste disposal site and that only a small portion of the wastes received at the site would require greater confinement disposal. The document is organized into sections addressing: facility planning process; facility construction; waste loading and handling; radiological safety planning; operations procedures; and engineering cost studies. While primarily written for low-level waste management site operators and managers, a detailed economic assessment section is included that should assist planners in performing cost analyses. Economic assessments for both commercial and US government greater confinement disposal facilities are included. The estimated disposal costs range from $27 to $104 per cubic foot for a commercial facility and from $17 to $60 per cubic foot for a government facility. These costs are based on average site preparation, construction, and waste loading costs for both contact- and remote-handled wastes. 14 figures, 22 tables

    Factors associated with paid work were examined in a probabilistic sample of 3,320 adults (50-69 years) in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil. Prevalence of paid work was 62.8% in men and 35.8% in women. For both men and women, paid work was positively associated with schooling and negatively associated with self-rated health. The probability of having paid work was higher for single women and those who knew someone that had suffered discrimination at the workplace. For men, prevalence of paid work varied from 67.2% in those with ≥ 8 years of schooling and better self-rated health, as compared to 37.8% in those with less schooling and poor self-rated health (PR = 0.56; 95%CI: 0.37-0.87). In women, the corresponding prevalence rates were 42.1% and 3.6% (PR = 0.09; 95%CI: 0.03-0.26). For women with little schooling and poor self-rated health, the likelihood of having paid work was ten times lower than for their male counterparts.

    To investigate the impact of prevalence correction of population denominators on myocardial infarction (MI) incidence rates, rate ratios, and rate differences in Aboriginal vs. non-Aboriginal Western Australians aged 25-74 years during the study period 2000-2004. Person-based linked hospital and mortality data sets were used to estimate the number of prevalent and first-ever MI cases each year from 2000 to 2004 using a 15-year look-back period. Age-specific and -standardized MI incidence rates were calculated using both prevalence-corrected and -uncorrected population denominators, by sex and Aboriginality. The impact of prevalence correction on rates increased with age, was higher for men than women, and substantially greater for Aboriginal than non-Aboriginal people. Despite the systematic underestimation of incidence, prevalence correction had little impact on the Aboriginal to non-Aboriginal age-standardized rate ratios (6% and 4% underestimate in men and women, respectively), although the impact on rate differences was more marked (12% and 6%, respectively). The percentage underestimate of differentials was greater at older ages. Prevalence correction of denominators, while more accurate, is difficult to apply and may add modestly to the quantification of relative disparities in MI incidence between populations. Absolute incidence disparities using uncorrected denominators may have an error >10%. Copyright © 2011 Elsevier Inc. All rights reserved.

    Full Text Available The purpose of this study was to estimate the degree of seasonality and prevalence of winter- and summer-type seasonal affective disorder (SAD in African immigrant college students in comparison with African American peers. A convenience sample of 246 African immigrants and 599 African Americans studying in Washington, D.C. completed the Seasonal Pattern Assessment Questionnaire (SPAQ, which was used to calculate a global seasonality score (GSS and to estimate the prevalence of winter- and summer-type SAD. Degree of seasonality was related to a complex interaction between having general awareness of SAD, ethnicity, and gender. A greater percentage of African students reported experiencing a problem with seasonal changes relative to African American students, and had summer SAD, but the groups did not differ on GSS and winter SAD. African students reported more difficulties with seasonal changes than their African American peers, which could represent a manifestation of incomplete acclimatization to a higher latitude and temperate climate. As Africans also had a greater rate of summer SAD, this argues against acclimatization to heat.

    2015-01-01

    Domestic violence is a significant public health issue. Prevalence rates for same-sex domestic violence vary because of methodological issues related to recruitment and definitions of sexual orientation. However, such prevalence rates are currently considered to be similar to slightly greater than other-sex prevalence rates. Research has identified differences between same-sex domestic violence and other-sex domestic violence, including internalized and externalized stressors associated with being a sexual minority that interact with domestic violence to create or exacerbate vulnerabilities, higher risk for complex trauma experiences, and difficulties accessing services. This review provides a critical review of the literature, focusing upon empirical findings regarding same-sex domestic violence.

  20. Search for greater stability in nuclear regulation

    Asselstine, J.K.

    1985-01-01

    The need for greater stability in nuclear regulation is discussed. Two possible approaches for dealing with the problems of new and rapidly changing regulatory requirements are discussed. The first approach relies on the more traditional licensing reform initiatives that have been considered off and on for the past decade. The second approach considers a new regulator philosophy aimed at the root causes of the proliferation of new safety requirements that have been imposed in recent years. For the past few years, the concepts of deregulation and regulatory reform have been in fashion in Washington, and the commercial nuclear power program has not remained unaffected. Many look to these concepts to provide greater stability in the regulatory program. The NRC, the nuclear industry and the administration have all been avidly pursuing regulatory reform initiatives, which take the form of both legislative and administrative proposals. Many of these proposals look to the future, and, if adopted, would have little impact on currently operating nuclear power plants or plants now under construction

    The city has proved to be the most successful form of human agglomeration and provides wide employment opportunities for its dwellers. As advances in robotics and artificial intelligence revive concerns about the impact of automation on jobs, a question looms: how will automation affect employment in cities? Here, we provide a comparative picture of the impact of automation across US urban areas. Small cities will undertake greater adjustments, such as worker displacement and job content substitutions. We demonstrate that large cities exhibit increased occupational and skill specialization due to increased abundance of managerial and technical professions. These occupations are not easily automatable, and, thus, reduce the potential impact of automation in large cities. Our results pass several robustness checks including potential errors in the estimation of occupational automation and subsampling of occupations. Our study provides the first empirical law connecting two societal forces: urban agglomeration and automation's impact on employment. © 2018 The Authors.

    Low-level radioactive waste (LLW) includes a broad spectrum of different radionuclide concentrations, half-lives, and hazards. Standard shallow-land burial practice can provide adequate protection of public health and safety for most LLW. A small volume fraction (approx. 1%) containing most of the activity inventory (approx. 90%) requires specific measures known as greater-confinement disposal (GCD). Different site characteristics and different waste characteristics - such as high radionuclide concentrations, long radionuclide half-lives, high radionuclide mobility, and physical or chemical characteristics that present exceptional hazards - lead to different GCD facility design requirements. Facility design alternatives considered for GCD include the augered shaft, deep trench, engineered structure, hydrofracture, improved waste form, and high-integrity container. Selection of an appropriate design must also consider the interplay between basic risk limits for protection of public health and safety, performance characteristics and objectives, costs, waste-acceptance criteria, waste characteristics, and site characteristics

    We conducted a survey of member facilities of the Japan Society of Ningen Dock to elucidate the actual status of chest computed tomography (CT) screening and the reasons for not being able to change to low-dose CT. We sent a questionnaire consisting of 9 items to 531 member facilities in July 2010, response by facsimile to obtain an analysis. The prevalence rate of low-dose CT lung cancer screening slightly increased to 35% in comparison with the former survey done in November 2008. Some facilities indicated some shift in tube current to a lower range even though this was insufficient to meet the definition of low-dose CT. This reflects their thinking of ''Even with knowledge, there is strong hesitation to change to low-dose CT''. Among the reasons why they did not change to low-dose CT, a priority for high quality images was the top reason among problems of devices and performance. Informed consent was not yet adequate. It is necessary for manufactures to develop better technology to improve the image quality of low-dose CT and to report enough information to clinicians. On the medical side, perception of the necessity for appropriate reduction of radiation dose and the decision to move to low-dose CT would be of crucial significance for facility heads as well as radiologists and technicians.

    Data are presented from a monitoring network of 18 bulk precipitation collectors and one wet-only collector in the urban area of Greater Manchester, in the north west of England. Weekly samples were analysed for all the major ions in precipitation along with gaseous nitrogen dioxide concentrations from diffusion tubes. Statistical analysis of the data shows significant spatial variation of non marine sulphate, nitrate, ammonium, acidity and calcium concentrations, and nitrogen dioxide concentrations. Calcium is thought to be responsible for the buffering of acidity and is of local origin. Wet deposition is the likely removal process for calcium in the atmosphere and probably by below cloud scavenging. Nitrate and ammonium concentrations and depositions show close spatial, temporal and statistical association. Examination of high simultaneous episodes of nitrate and ammonium deposition shows that these depositions cannot be explained in terms of trajectories and it is suggested that UK emissions of ammonia may be important. Statistical analysis of the relationships between nitrate and ammonium depositions, concentrations and precipitation amount suggest that ammonia from mesoscale sources reacts reversibly with nitric acid aerosol and is removed by below cloud scavenging. High episodes of the deposition of non marine sulphate are difficult to explain by trajectory analysis alone, perhaps suggesting local sources. In a comparison between wet deposition and bulk deposition, it was shown that only 15.2% of the non marine sulphur was dry deposited to the bulk precipitation collector. 63 refs., 86 figs., 31 tabs.

    The aim of this study was to review musculoskeletal disorder (MSD) prevalence among surgeons performing minimally invasive surgery. Advancements in laparoscopic surgery have primarily focused on enhancing patient benefits. However, compared with open surgery, laparoscopic surgery imposes greater ergonomic constraints on surgeons. Recent reports indicate a 73% to 88% prevalence of physical complaints among laparoscopic surgeons, which is greater than in the general working population, supporting the need to address the surgeons' physical health. To summarize the prevalence of MSDs among surgeons performing laparoscopic surgery, we performed a systematic review of studies addressing physical ergonomics as a determinant, and reporting MSD prevalence. On April 15 2016, we searched Pubmed, EMBASE, the Cochrane Library, Web of Science, CINAHL, and PsychINFO. Meta-analyses were performed using the Hartung-Knapp-Sidik-Jonkman method. We identified 35 articles, including 7112 respondents. The weighted average prevalence of complaints was 74% [95% confidence interval (95% CI) 65-83]. We found high inconsistency across study results (I = 98.3%) and the overall response rate was low. If all nonresponders were without complaints, the prevalence would be 22% (95% CI 16-30). From the available literature, we found a 74% prevalence of physical complaints among laparoscopic surgeons. However, the low response rates and the high inconsistency across studies leave some uncertainty, suggesting an actual prevalence of between 22% and 74%. Fatigue and MSDs impact psychomotor performance; therefore, these results warrant further investigation. Continuous changes are enacted to increase patient safety and surgical care quality, and should also include efforts to improve surgeons' well-being.

    Demonstrations are being conducted in association with the disposal of a high activity low-level waste (LLW) stream. The waste stream in question will result from the cement solidification of decanted liquids from the Melton Valley Storage Tanks (MVST). The solid waste will be produced beginning in mid summer 1988. It is anticipated to have significant concentrations of Cs-137 and Sr-90, with smaller amounts of other radionuclides and <100 nCi/gm of TRU. The solid waste forms are expected to have surface dose rates in the 1 to 2 r/hr range. The solid waste will also contain several chemical species at concentrations which are below those of concern, but which may present enhanced corrosion potential for the disposal units. 2 refs., 5 figs

    Colonization of islands can dramatically influence the evolutionary trajectories of organisms, with both deterministic and stochastic processes driving adaptation and diversification. Some island colonists evolve extremely large or small body sizes, presumably in response to unique ecological circumstances present on islands. One example of this phenomenon, the Greater Antillean boas, includes both small (<90 cm) and large (4 m) species occurring on the Greater Antilles and Bahamas, with some islands supporting pairs or trios of body-size divergent species. These boas have been shown to comprise a monophyletic radiation arising from a Miocene dispersal event to the Greater Antilles, though it is not known whether co-occurrence of small and large species is a result of dispersal or in situ evolution. Here, we provide the first comprehensive species phylogeny for this clade combined with morphometric and ecological data to show that small body size evolved repeatedly on separate islands in association with specialization in substrate use. Our results further suggest that microhabitat specialization is linked to increased rates of head shape diversification among specialists. Our findings show that ecological specialization following island colonization promotes morphological diversity through deterministic body size evolution and cranial morphological diversification that is contingent on island- and species-specific factors. © 2016 The Author(s).

    Myiasis is the infestation of tissues of live vertebrate animals and humans with dipterous larvae. In sub-Saharan Africa, Cordylobia anthropohaga and Cordylobia rodhaini are known to be responsible for cutaneous myiasis in animals and humans. Human cases of myiasis, purportedly acquired in Ghana but diagnosed in other countries, have been reported; however, published data on its occurrence in animals in Ghana is unavailable. This study assessed the prevalence of canine myiasis among owned dogs in the Greater Accra region (GAR) of Ghana. A cross-sectional study was conducted in the Greater Accra region of Ghana, selected for being the region with the highest estimated population density of owned dogs. Physical examination and demographic characteristics of the study dogs were assessed. Management of the dogs was assessed through a questionnaire administered to the dog owners. A total of 392 owned dogs were sampled. Twenty-nine (7.4%) had cutaneous myiasis caused by C. rodhaini. In addition, one (0.2%) of the dogs had intestinal myiasis, with Dermatobia hominis as the offending larvae. Among the breeds of dogs with myiasis, the mongrel was most affected, with 24 (82.8%) out of the 29 cases. The mongrels, majority of which (24; 82.8%) were males, were left to roam freely in the community. Results from this study demonstrate that C. rodhaini and D. hominis are important causes of myiasis in owned dogs in the GAR of Ghana. Dogs could play a role in the spread of myiasis to humans, with its attendant public health implications.

    Gestational diabetes is associated with a high risk of type 2 diabetes. However, progression rates among Indigenous women in Australia who experience high prevalence of gestational diabetes are unknown. This retrospective cohort study includes all births to women at a regional hospital in Far North Queensland, Australia, coded as having 'gestational diabetes' from 1 January 2004 to 31 December 2010 (1098 births) and receiving laboratory postpartum screening from 1 January 2004 to 31 December 2011 (n = 483 births). Women who did not receive postpartum screening were excluded from the denominator. Data were linked between hospital electronic records, routinely collected birth data and laboratories, with sample validation by reviews of medical records. Analysis was conducted using Cox-proportional regression models. Indigenous women had a greater than fourfold risk of developing type 2 diabetes within 8 years of having gestational diabetes, compared with non-Indigenous women (hazards ratio 4.55, 95% confidence interval 2.63-7.88, p Australian women have a greater than fourfold risk of developing type 2 diabetes after gestational diabetes. Strategies are urgently needed to reduce rates of type 2 diabetes by supporting a healthy weight and breastfeeding and to improve postpartum screening among Indigenous women with gestational diabetes.

    The aim of this study is to find out the overall prevalence rates for the major forms of abuse among adolescents in the Kingdom of Saudi Arabia and the differences in prevalence by age, gender and living arrangement. The cross-sectional study was conducted in secondary high schools in five of the 13 main regions of Kingdom of Saudi Arabia during 2012. Through a multistage stratified sampling technique, a sample (n = 16 939) of adolescents (15-19 years) were identified and invited to participate. The ISPCAN Child Abuse Screening Tool - Child was used for data collection. The previous year's occurrence of violence exposure, psychological, physical and sexual abuse, and neglect were assessed. Nearly 90% of the adolescents were between 16 and 18 years of age, and over 80% were cared for by both of their biological parents. Annual prevalence of various forms of abuse in the year before the 2012 assessment ranged between 0.10 and 0.65, with the lowest rate for sexual abuse and the highest for psychological abuse. Significantly, greater rates of all forms of abuse/exposure were found when participants lived with their mother or father only (versus with both), and even greater rates for all when they lived with their biological parent and a step-parent. Rates for violence exposure, psychological abuse and neglect were significantly greater for girls, and rate of sexual abuse was greater for boys. More attention should be given to the effect of adolescent maltreatment particularly among girls. In addition, sexual abuse prevention programme should be targeted among boys. © 2016 John Wiley & Sons Ltd.

    A cross-sectional study was conducted to estimate the prevalence of clinical lameness in high-producing Holstein cows housed in 50 freestall barns in Minnesota during summer. Locomotion and body condition scoring were performed on a total of 5,626 cows in 53 high-production groups. Cow records were collected from the nearest Dairy Herd Improvement Association test date, and herd characteristics were collected at the time of the visit. The mean prevalence of clinical lameness (proportion of cows with locomotion score >or=3 on a 1-to-5 scale, where 1 = normal and 5 = severely lame), and its association with lactation number, month of lactation, body condition score, and type of stall surface were evaluated. The mean prevalence of clinical lameness was 24.6%, which was 3.1 times greater, on average, than the prevalence estimated by the herd managers on each farm. The prevalence of lameness in first-lactation cows was 12.8% and prevalence increased on average at a rate of 8 percentage units per lactation. There was no association between the mean prevalence of clinical lameness and month of lactation (for months 1 to 10). Underconditioned cows had a higher prevalence of clinical lameness than normal or overconditioned cows. The prevalence of lameness was lower in freestall herds with sand stalls (17.1%) than in freestall herds with mattress stall surfaces (27.9%). Data indicate that the best 10th percentile of dairy farms had a mean prevalence of lameness of 5.4% with only 1.47% of cows with locomotion score = 4 and no cows with locomotion score = 5.

    -sectional population studies were carried out in the city. Interviewers were previously trained and applied standardized questionnaires during visits to families with children under 5 years old. The following variables were investigated: family income, maternal education, type of construction of home (wooden/masonry etc., availability of toilet, running water, sewage system and domestic appliances. Data collected on the children themselves included number of antenatal consultations and age at first antenatal, type of delivery and medical care received during delivery, breastfeeding and dietary patterns, morbidity and health services utilization. Children were weighed and measured for height/length. Comparisons of frequencies between the two datasets were made using the chi-square test. RESULTS: In 1995, 395 children were studied and in 2004 there were 384. During the intervening period improvements had taken place in type of construction, number of homes with flush toilet, the availability of running water and in breastfeeding pattern and duration. The frequency of diarrhea reduced, while rates of basic vaccination coverage, growth monitoring, patients in possession of their own medical cards and reporting of birth weights all increased. There was a deterioration in families' purchasing power and in the mean number of antenatal consultations. The prevalence of childhood obesity increased by 92%, while the incidence of malnutrition remained practically unchanged. CONCLUSIONS: Comparing health indicators from the two periods revealed that, in addition to improvements in the majority of the indicators assessed, there had been a substantial increase in the prevalence of childhood obesity.

    Bullying involvement in any form can have lasting physical and emotional consequences for adolescents. For programs and policies to best safeguard youth, it is important to understand prevalence of bullying across cyber and traditional contexts. We conducted a thorough review of the literature and identified 80 studies that reported corresponding prevalence rates for cyber and traditional bullying and/or aggression in adolescents. Weighted mean effect sizes were calculated, and measurement features were entered as moderators to explain variation in prevalence rates and in traditional-cyber correlations within the sample of studies. Prevalence rates for cyber bullying were lower than for traditional bullying, and cyber and traditional bullying were highly correlated. A number of measurement features moderated variability in bullying prevalence; whereas a focus on traditional relational aggression increased correlations between cyber and traditional aggressions. In our meta-analytic review, traditional bullying was twice as common as cyber bullying. Cyber and traditional bullying were also highly correlated, suggesting that polyaggression involvement should be a primary target for interventions and policy. Results of moderation analyses highlight the need for greater consensus in measurement approaches for both cyber and traditional bullying. Copyright © 2014 Society for Adolescent Health and Medicine.

    I examined the relationship of recalled and diary recorded frequency of penile-vaginal intercourse (FSI), noncoital partnered sexual activity, and masturbation to measured waist and hip circumference in 120 healthy adults aged 19-38. Slimmer waist (in men and in the sexes combined) and slimmer hips (in men and women) were associated with greater FSI. Slimmer waist and hips were associated with rated importance of intercourse for men. Noncoital partnered sexual activity had a less consistent association with slimness. Slimmer waist and hips were associated with less masturbation (in men and in the sexes combined). I discuss the results in terms of differences between different sexual behaviors, attractiveness, emotional relatedness, physical sensitivity, sexual dysfunction, sociobiology, psychopharmacological aspects of excess fat and carbohydrate consumption, and implications for sex therapy.

  5. The metabolic syndrome: prevalence, CHD risk, and treatment.

    2006-01-01

    An increased risk of coronary heart disease (CHD) morbidity and mortality is associated with the metabolic syndrome, a condition characterized by the concomitant presence of several abnormalities, including abdominal obesity, dyslipidemia, hypertension, insulin resistance (with or without glucose intolerance or diabetes), microalbuminuria, prothrombotic, and proinflammatory states. Estimates of the prevalence of the metabolic syndrome indicate that this condition is now common and likely to increase dramatically over the coming decades, in parallel with greater rates of obesity and Type 2 diabetes. Risk factors for the metabolic syndrome are already present in obese children and adolescents. Thus, identifying and treating all affected individuals promptly and optimally are critical to ensure that this potentially challenging healthcare burden is minimized. Here, we review the prevalence of the metabolic syndrome, dyslipidemias, and CHD risk. Although changes in lifestyle are fundamental to reducing many of the CHD risk factors associated with the metabolic syndrome, pharmacologic interventions also play an important role. Retrospective subanalyses of the effects of statins on coronary event rates and lipid levels in patients with the metabolic syndrome included in clinical trials indicate that these agents are beneficial in correcting the extensive lipid abnormalities that are frequently present in these individuals. However, the optimal management of metabolic syndrome dyslipidemia will depend on the outcomes of future prospective clinical trials. This review examines the underlying causes and prevalence of the metabolic syndrome and its impact on CHD morbidity and mortality and discusses the role of statins in optimizing its management.

    Dumping syndrome is one of ten most common complications in morbidly obese patients operated. Recent studies in relation to type 2 diabetes mellitus (DM2) in patients submitted to gastric bypass led us to examine the different outcomes in this group of patients. Our objective was to determine the difference in the prevalence of dumping syndrome in patients with DM2 submitted to gastric bypass. In this retrospective study, 49 diabetic and 54 non-diabetic morbidly obese patients were submitted to gastric bypass and followed up at 3, 6, and 12 months after surgery. The occurrence of dumping was determined by the patient's medical chart, where it was considered positive if recorded in at least one of three evaluations. The 103 patients evaluated had a mean BMI of 49.5 +/- 9.3 kg/m(2) and mean age of 38 +/- 9.7 years, with 75.7% being women. The prevalence of dumping syndrome in this population was 24.3%. The prevalence of dumping was greater in patients with DM2 (44.9%) when compared to the control group (5.6%; p DM2 as the only variable associated with dumping syndrome. Dumping syndrome is a common postoperative complication in gastric bypass. Patients with DM2 show a greater postoperative prevalence of dumping.

    Ageing and urbanization leading to sedentary lifestyles have been the major explanations proposed for a dramatic rise in diabetes worldwide and have been the variables used to predict future diabetes rates. However, a transition to Western diets has been suggested as an alternative driver. We sought to determine what socio-economic and dietary factors are the most significant population-level contributors to diabetes prevalence rates internationally. Multivariate regression models were used to study how market sizes of major food products (sugars, cereals, vegetable oils, meats, total joules) corresponded to diabetes prevalence, incorporating lagged and cumulative effects. The underlying social determinants of food market sizes and diabetes prevalence rates were also studied, including ageing, income, urbanization, overweight prevalence and imports of foodstuffs. Data were obtained from 173 countries. Population-based survey recipients were the basis for diabetes prevalence and food market data. We found that increased income tends to increase overall food market size among low- and middle-income countries, but the level of food importation significantly shifts the content of markets such that a greater proportion of available joules is composed of sugar and related sweeteners. Sugar exposure statistically explained why urbanization and income have been correlated with diabetes rates. Current diabetes projection methods may estimate future diabetes rates poorly if they fail to incorporate the impact of nutritional factors. Imported sugars deserve further investigation as a potential population-level driver of global diabetes.

    Greater trochanteric pain syndrome is a common condition with clinical features of pain and tenderness at the lateral aspect of the hip. Diagnosing the origin of greater trochanteric pain is important because the treatment varies depending on the cause. We hypothesized that sonographic evaluation of sources for greater trochanteric pain syndrome would show that bursitis was not the most commonly encountered abnormality. We performed a retrospective review of musculoskeletal sonographic examinations performed at our institution over a 6-year period for greater trochanteric pain syndrome; completed a tabulation of the sonographic findings; and assessed the prevalence of trochanteric bursitis, gluteal tendon abnormalities, iliotibial band abnormalities, or a combination of findings. Prevalence of abnormal findings, associations of bursitis, gluteal tendinosis, gluteal tendon tears, and iliotibial band abnormalities were calculated. The final study population consisted of 877 unique patients: 602 women, 275 men; average age, 54 years; and age range, 15-87 years). Of the 877 patients with greater trochanteric pain, 700 (79.8%) did not have bursitis on ultrasound. A minority of patients (177, 20.2%) had trochanteric bursitis. Of the 877 patients with greater trochanteric pain, 438 (49.9%) had gluteal tendinosis, four (0.5%) had gluteal tendon tears, and 250 (28.5%) had a thickened iliotibial band. The cause of greater trochanteric pain syndrome is usually some combination of pathology involving the gluteus medius and gluteus minimus tendons as well as the iliotibial band. Bursitis is present in only the minority of patients. These findings have implications for treatment of this common condition.

    Full Text Available Congenital malformation (CM will begin to emerge as one of the major childhood health problems .Treatment and rehabilitation of children with congenital malformations are costly and complete recovery is usually impossible. The aim of this study was to determine frequency of CM in Yazd central city of the Islamic Republic of Iran to find out if there has been any difference in the rate and types of CM in this area. This descriptive-observational study carried on 4800 births delivered at all maternity hospitals in Yazd from October 2003 to June 2004. Prevalence of CM was 2.83% (2.86 % in male and 2.68 % in female out of the 136 cases 69(51.88% were males and 64 (48.12% were females and 3 with ambiguous genitalia. Positive family history of CM in sibling was in only 6 cases (4.41%.Overall, musculoskeletal (0.83%, central nerv-ous system (0.47% and genital system (0.37% were accounted as the most common. Frequency of CM was more seen in still birth (12.5% as in comparison to live birth (2.71%. There was not statistical difference be-tween prevalence of CM and neonatal's gender, gestational age, birth order and mother's age, drug ingestion, illness and parental consanguinity. In this study the overall prevalence of congenital malformation among the newborn was higher than those previous reported in Iran and determining the causes of this difference needs more extensive studies.

    Giardia has a wide range of host species and is a common cause of diarrhoeal disease in humans and animals. Companion animals are able to transmit a range of zoonotic diseases to their owners including giardiasis, but the size of this risk is not well known. The aim of this study was to analyse giardiasis prevalence rates in dogs and cats worldwide using a systematic search approach. Meta-analysis enabled to describe associations between Giardia prevalence and various confounding factors. Pooled prevalence rates were 15.2% (95% CI 13.8-16.7%) for dogs and 12% (95% CI 9.2-15.3%) for cats. However, there was very high heterogeneity between studies. Meta-regression showed that the diagnostic method used had a major impact on reported prevalence with studies using ELISA, IFA and PCR reporting prevalence rates between 2.6 and 3.7 times greater than studies using microscopy. Conditional negative binomial regression found that symptomatic animals had higher prevalence rates ratios (PRR) than asymptomatic animals 1.61 (95% CI 1.33-1.94) in dogs and 1.94 (95% CI 1.47-2.56) in cats. Giardia was much more prevalent in young animals. For cats >6 months, PRR=0.47 (0.42-0.53) and in dogs of the same age group PRR=0.36 (0.32-0.41). Additionally, dogs kept as pets were less likely to be positive (PRR=0.56 (0.41-0.77)) but any difference in cats was not significant. Faecal excretion of Giardia is common in dogs and slightly less so in cats. However, the exact rates depend on the diagnostic method used, the age and origin of the animal. What risk such endemic colonisation poses to human health is still unclear as it will depend not only on prevalence rates but also on what assemblages are excreted and how people interact with their pets.

    Background: Chronic kidney disease is an important risk factor for death and cardiovascular-related morbidity, but estimates to date of its prevalence in Canada have generally been extrapolated from the prevalence of end-stage renal disease. We used direct measures of kidney function collected from a nationally representative survey population to estimate the prevalence of chronic kidney disease among Canadian adults. Methods: We examined data for 3689 adult participants of cycle 1 of the Canadian Health Measures Survey (2007–2009) for the presence of chronic kidney disease. We also calculated the age-standardized prevalence of cardiovascular risk factors by chronic kidney disease group. We cross-tabulated the estimated glomerular filtration rate (eGFR) with albuminuria status. Results: The prevalence of chronic kidney disease during the period 2007–2009 was 12.5%, representing about 3 million Canadian adults. The estimated prevalence of stage 3–5 disease was 3.1% (0.73 million adults) and albuminuria 10.3% (2.4 million adults). The prevalence of diabetes, hypertension and hypertriglyceridemia were all significantly higher among adults with chronic kidney disease than among those without it. The prevalence of albuminuria was high, even among those whose eGFR was 90 mL/min per 1.73 m2 or greater (10.1%) and those without diabetes or hypertension (9.3%). Awareness of kidney dysfunction among adults with stage 3–5 chronic kidney disease was low (12.0%). Interpretation: The prevalence of kidney dysfunction was substantial in the survey population, including individuals without hypertension or diabetes, conditions most likely to prompt screening for kidney dysfunction. These findings highlight the potential for missed opportunities for early intervention and secondary prevention of chronic kidney disease. PMID:23649413

    To determine the characteristics of the newly injured and prevalent population with spinal cord injury (SCI) and assess trends over time. Prospective cohort study. SCI Model Systems and Shriners Hospital SCI units. The study population included people whose injuries occurred from 1935 to 2008 (N=45,442). The prevalent population was estimated based on those who were still alive in 2008. Losses to follow-up (approximately 10%) were excluded from the prevalent population. Not applicable. Demographic and injury characteristics, mortality, self-reported health, rehospitalization, FIM, Craig Handicap Assessment and Reporting Technique, and the Diener Satisfaction with Life Scale. Mean age at injury increased 9 years since the 1970s. Injuries caused by falls and injuries resulting in high-level tetraplegia and ventilator dependency are increasing, while neurologically complete injuries are decreasing. Discharge to a nursing home is increasing. The mean age of the prevalent population is slightly higher than that of newly injured individuals, and the percentage of incident and prevalent cases older than 60 years is the same (13%). Prevalent cases tend to be less severely injured than incident cases, and less than 5% of prevalent cases reside in nursing homes. Within the prevalent population, life satisfaction and community participation are greater among persons who are at least 30 years postinjury. These findings are a result of very high mortality rates observed after 60 years of age. Within the prevalent population, the percentage of elderly persons will not increase meaningfully. Those who reach older ages will typically have incomplete and/or lower-level injuries and will have relatively high degrees of independence and overall good health.

    Doelwitte: Die doel van die studie was om die faktore wat in die Groter Giyani Munisipaliteit tot lae genesingskoerse onder TB-pasiënte lei, te ondersoek en te beskryf, soos deur pasiënte gesien. Metode: Die studie is in die Groter Giyani Munisipaliteit in die Limpopo Provinsie gehou, waar die genesingskoers vir TB tussen 14% en 94% is. Die navorsing in hierdie studie was kwalitatief, verkennend, beskrywend en kontekstueel van aard. Die populasie het bestaan uit alle gediagnoseerde TB-pasiënte wat vir behandeling en sorg na primêre gesondheidsorgfasiliteite verwys is. Nie-waarskynlikheid, doelgerigte steekproefneming is gebruik om TB-pasiënte en gesondheidsfasiliteite te kies wat ’n laer genesingskoers as die nasionale doelwit van 85% het. Een pasiënt uit elke primêre gesondheidsorgfasiliteit is by die steekproef ingesluit. ‘n Diepgaande persoonlike onderhoud is gebruik om data met behulp van ‘n onderhoudgids in te samel. Resultate: Die bevindinge toon dat die meeste van die TB-pasiënte uit arm gesinne kom, wat dit vir hulle moeilik maak om finansiële en voedselsekerheid te hê. Die gesondheidsfasiliteite se voedselaanvullings en TB-medisyne raak dikwels op. Kulturele oortuigings oor TB lei ook daartoe dat TB-pasiënte by tradisionele gesondheidsorgpraktisyns en geloofsgebaseerde genesers hulp soek. Gevolgtrekking: Dit is nodig dat ‘n beleid oor toesig oor die behandeling van ontslaande TB-pasiënte wat tuis aansterk, opgestel word. Gesondheidsorgfasiliteite behoort ook seker te maak dat daar genoeg medisyne vir hierdie pasiënte is, aangesien ‘n gebrek aan medisyne daartoe kan lei dat die pasiënte ophou om hulle medikasie te gebruik.

    Full Text Available This retrospective study assessed the prevalence of moderate to severe chronic kidney disease (CKD among nursing home (NH residents with type 2 diabetes. The pattern of oral antidiabetic drug (OAD use and their concordance with the National Kidney Foundation (NKF guideline and prescribing information (PI was also assessed. About half (47% of diabetic residents had moderate to severe CKD. A little over a quarter of the 186 residents using OADs received at least one NKF-discordant OAD prescription. Metformin was the most commonly misused OAD. PI nonconcordance was observed in 58.6% of residents and was highest in glipizide and metformin users. With the high prevalence of moderate to severe CKD in NH residents with diabetes, physicians should consider residents’ renal function when choosing treatment plans and review treatments regularly to check compliance with the NKF guidelines or PIs.

    2018-01-01

    There have been numerous studies of glaciers in the Greater Caucasus, but none that have generated a modern glacier database across the whole mountain range. Here, we present an updated and expanded glacier inventory at three time periods (1960, 1986, 2014) covering the entire Greater Caucasus. Large-scale topographic maps and satellite imagery (Corona, Landsat 5, Landsat 8 and ASTER) were used to conduct a remote-sensing survey of glacier change, and the 30 m resolution Advanced Spaceborne Thermal Emission and Reflection Radiometer Global Digital Elevation Model (ASTER GDEM; 17 November 2011) was used to determine the aspect, slope and height distribution of glaciers. Glacier margins were mapped manually and reveal that in 1960 the mountains contained 2349 glaciers with a total glacier surface area of 1674.9 ± 70.4 km2. By 1986, glacier surface area had decreased to 1482.1 ± 64.4 km2 (2209 glaciers), and by 2014 to 1193.2 ± 54.0 km2 (2020 glaciers). This represents a 28.8 ± 4.4 % (481 ± 21.2 km2) or 0.53 % yr-1 reduction in total glacier surface area between 1960 and 2014 and an increase in the rate of area loss since 1986 (0.69 % yr-1) compared to 1960-1986 (0.44 % yr-1). Glacier mean size decreased from 0.70 km2 in 1960 to 0.66 km2 in 1986 and to 0.57 km2 in 2014. This new glacier inventory has been submitted to the Global Land Ice Measurements from Space (GLIMS) database and can be used as a basis data set for future studies.

    This study aimed to assess the prevalence of dental pain among adults and older people living in Brazil's State capitals. Information was gathered from the Telephone Survey Surveillance System for Risk and Protective Factors for Chronic Diseases (VIGITEL) in 2009 (n = 54,367). Dental pain was the outcome. Geographic region, age, gender, race, schooling, private health coverage, smoking, and soft drink consumption were the explanatory variables. Multilevel Poisson regression models were performed. Prevalence of dental pain was 15.2%; Macapá and São Luís had prevalence rates greater than 20%; all capitals in the South and Southeast, plus Cuiabá, Campo Grande, Maceió, Recife, and Natal had prevalence rates less than 15%. Factors associated with increased prevalence of dental pain were the North and Northeast regions, female gender, black/brown skin color, lack of private health insurance, smoking, and soft drink consumption. Dental pain is a public health problem that should be monitored by health surveillance systems.

    We sought to improve public health surveillance by using a geographic analysis of emergency department (ED) visits to determine local chronic disease prevalence. Using an all-payer administrative database, we determined the proportion of unique ED patients with diabetes, hypertension, or asthma. We compared these rates to those determined by the New York City Community Health Survey. For diabetes prevalence, we also analyzed the fidelity of longitudinal estimates using logistic regression and determined disease burden within census tracts using geocoded addresses. We identified 4.4 million unique New York City adults visiting an ED between 2009 and 2012. When we compared our emergency sample to survey data, rates of neighborhood diabetes, hypertension, and asthma prevalence were similar (correlation coefficient = 0.86, 0.88, and 0.77, respectively). In addition, our method demonstrated less year-to-year scatter and identified significant variation of disease burden within neighborhoods among census tracts. Our method for determining chronic disease prevalence correlates with a validated health survey and may have higher reliability over time and greater granularity at a local level. Our findings can improve public health surveillance by identifying local variation of disease prevalence.

    Compulsive buying (uncontrolled urges to buy, with resulting significant adverse consequences) has been estimated to affect from 1.8% to 16% of the adult U.S. population. To the authors' knowledge, no study has used a large general population sample to estimate its prevalence. The authors conducted a random sample, national household telephone survey in the spring and summer of 2004 and interviewed 2,513 adults. The interviews addressed buying attitudes and behaviors, their consequences, and the respondents' financial and demographic data. The authors used a clinically validated screening instrument, the Compulsive Buying Scale, to classify respondents as either compulsive buyers or not. The rate of response was 56.3%, which compares favorably with rates in federal national health surveys. The cooperation rate was 97.6%. Respondents included a higher percentage of women and people ages 55 and older than the U.S. adult population. The estimated point prevalence of compulsive buying among respondents was 5.8% (by gender: 6.0% for women, 5.5% for men). The gender-adjusted prevalence rate was 5.8%. Compared with other respondents, compulsive buyers were younger, and a greater proportion reported incomes under 50,000 US dollars. They exhibited more maladaptive responses on most consumer behavior measures and were more than four times less likely to pay off credit card balances in full. A study using clinically valid interviews is needed to evaluate these results. The emotional and functional toll of compulsive buying and the frequency of comorbid psychiatric disorders suggests that studies of treatments and social interventions are warranted.

    The Greater Mekong Subregion (GMS), comprised of six countries including Cambodia, China's Yunnan Province, Lao PDR, Myanmar (Burma), Thailand and Vietnam, is one of the most threatening foci of malaria. Since the initiation of the WHO's Mekong Malaria Program a decade ago, malaria situation in the GMS has greatly improved, reflected in the continuous decline in annual malaria incidence and deaths. However, as many nations are moving towards malaria elimination, the GMS nations still face great challenges. Malaria epidemiology in this region exhibits enormous geographical heterogeneity with Myanmar and Cambodia remaining high-burden countries. Within each country, malaria distribution is also patchy, exemplified by ‘border malaria’ and ‘forest malaria’ with high transmission occurring along international borders and in forests or forest fringes, respectively. ‘Border malaria’ is extremely difficult to monitor, and frequent malaria introductions by migratory human populations constitute a major threat to neighboring, malaria-eliminating countries. Therefore, coordination between neighboring countries is essential for malaria elimination from the entire region. In addition to these operational difficulties, malaria control in the GMS also encounters several technological challenges. Contemporary malaria control measures rely heavily on effective chemotherapy and insecticide control of vector mosquitoes. However, the spread of multidrug resistance and potential emergence of artemisinin resistance in Plasmodium falciparum make resistance management a high priority in the GMS. This situation is further worsened by the circulation of counterfeit and substandard artemisinin-related drugs. In most endemic areas of the GMS, P. falciparum and P. vivax coexist, and in recent malaria control history, P. vivax has demonstrated remarkable resilience to control measures. Deployment of the only registered drug (primaquine) for the radical cure of vivax malaria is

    Full Text Available This article conducts a systematic review on the prevalence of dating violence in adolescents and young people. Primary studies about physical, psychological and sexual dating violence (perpetration and victimization were analyzed. A total of 1,221 references were found and, out of those, 113 met the pre-established quality criteria (studies had to have used assessment tolos with evidence of reliability and validity, in samples over 500 participants or obtained through probabilistic sampling. The results showed a great variability of figures on the prevalence of dating violence. Specifically, the percentages range from 3.8% to 41.9% in perpetrated physical violence; from 0.4% to 57.3% in victimized physical violence; from 4.2% to 97% in perpetrated psychological violence; from 8.5% to 95.5% in victimized psychological violence; from 1.2% to 58.8% in perpetrated sexual violence; and finally, from 0.1% to 64.6% in victimized sexual violence. The results suggest a higher prevalence in the perpetration of psychological aggression by women and sexual violence by men; greater psychological and sexual victimization in women; and slightly higher rates of aggression in adolescents than in young adults. Also, in many of the papers the aggression had a bidirectional nature.

    To determine the impact of tobacco control policies and mass media campaigns on smoking prevalence in Australian adults. Data for calculating the average monthly prevalence of smoking between January 2001 and June 2011 were obtained via structured interviews of randomly sampled adults aged 18 years or older from Australia's five largest capital cities (monthly mean number of adults interviewed: 2375). The influence on smoking prevalence was estimated for increased tobacco taxes; strengthened smoke-free laws; increased monthly population exposure to televised tobacco control mass media campaigns and pharmaceutical company advertising for nicotine replacement therapy (NRT), using gross ratings points; monthly sales of NRT, bupropion and varenicline; and introduction of graphic health warnings on cigarette packs. Autoregressive integrated moving average (ARIMA) models were used to examine the influence of these interventions on smoking prevalence. The mean smoking prevalence for the study period was 19.9% (standard deviation: 2.0%), with a drop from 23.6% (in January 2001) to 17.3% (in June 2011). The best-fitting model showed that stronger smoke-free laws, tobacco price increases and greater exposure to mass media campaigns independently explained 76% of the decrease in smoking prevalence from February 2002 to June 2011. Increased tobacco taxation, more comprehensive smoke-free laws and increased investment in mass media campaigns played a substantial role in reducing smoking prevalence among Australian adults between 2001 and 2011.

    Identifying those infected with tuberculosis (TB) is an important component of any strategy for reducing TB transmission and population prevalence. The Stop TB Global Partnership recently launched an initiative with a focus on key populations at greater risk for TB infection or poor clinical outcomes, due to housing and working conditions, incarceration, low household income, malnutrition, co-morbidities, exposure to tobacco and silica dust, or barriers to accessing medical care. To achieve operational targets, the global health community needs effective, low cost, and large-scale strategies for identifying key populations. Using South Africa as a test case, we assess the feasibility and effectiveness of targeting active case finding to populations with TB risk factors identified from regularly collected sources of data. Our approach is applicable to all countries with TB testing and census data. It allows countries to tailor their outreach activities to the particular risk factors of greatest significance in their national context. We use a national database of TB test results to estimate municipality-level TB infection prevalence, and link it to Census data to measure population risk factors for TB including rates of urban households, informal settlements, household income, unemployment, and mobile phone ownership. To examine the relationship between TB prevalence and risk factors, we perform linear regression analysis and plot the set of population characteristics against TB prevalence and TB testing rate by municipality. We overlay lines of best fit and smoothed curves of best fit from locally weighted scatter plot smoothing. Higher TB prevalence is statistically significantly associated with more urban municipalities (slope coefficient β1 = 0.129, p informal settlement households (β1 = 0.021, p = 0.136, R2 = 0.014). These analyses reveal that the set of characteristics identified by the Global Plan as defining key populations do not adequately predict

    To evaluate the association between metabolic syndrome (MetS) and proliferative inflammatory atrophy (PIA) in patients with suspected prostate cancer (PCa). From June 2015 to July 2016, we conducted the FIERY (Flogosis Increased Events of pRostatic biopsY) study at the Urology section, Department of Surgery of the University of Catania (Local registration number: #131/2015). A total of 205 patients with elevated prostate-specific antigen (≥ 4 ng/ml) or clinical suspicion of PCa who underwent primary transperineal prostate biopsy were included in this cross-sectional study. The assessment of PIA, HGPIN, and PCa were performed by 2 experienced pathologists and samples were investigated for the presence of an inflammatory infiltrate, according to the Irani score. Primary and secondary Gleason grade of tumor in positive biopsies were evaluated according to the 2016 ISUP Modified Gleason System. In the entire cohort, median age was 68.0 (interquartile range: 62.0-74.5), median prostate-specific antigen was 6.5 (interquartile range: 5.51-9.57). The prevalence of MetS was 34.1%, the detection rate of PCa was 32.7%, the rate of PIA was 28.3%, the rate of HGPIN was 32.2%, whereas the rate of severe intraprostatic inflammation (Irani-score ≥4) was 28.8%. When comparing clinical and histological variables in patients without and with PIA, metabolic aberrations where not significantly different in both groups. We did not find statistical association in detection rate of PCa (29.3% vs. 34.0%; P = 0.07) and HGPIN (27.6% vs. 34.0%; P = 0.37) in patients with and without PIA, respectively. When considering metabolic aberrations, MetS was not associated with Irani-score ≥4 (28.6% vs. 28.4%; P = 0.96) and none of each component was statistically predictive of severe inflammation. At the multivariable logistic regression analysis, PIA, HGPIN, and MetS were not associated with greater risk of PCa. In this study, we did not show an association between MetS and PIA and PCa

    Background Buruli ulcer (BU) disease, caused by infection with the environmental mycobacterium M. ulcerans, is an emerging infectious disease in many tropical and sub-tropical countries. Although vectors and modes of transmission remain unknown, it is hypothesized that the transmission of BU disease is associated with human activities in or around aquatic environments, and that characteristics of the landscape (e.g., land use/cover) play a role in mediating BU disease. Several studies performed at relatively small spatial scales (e.g., within a single village or region of a country) support these hypotheses; however, if BU disease is associated with land use/cover characteristics, either through spatial constraints on vector-host dynamics or by mediating human activities, then large-scale (i.e., country-wide) associations should also emerge. The objectives of this study were to (1) investigate associations between BU disease prevalence in villages in Benin, West Africa and surrounding land use/cover patterns and other map-based characteristics, and (2) identify areas with greater and lower than expected prevalence rates (i.e., disease clusters) to assist with the development of prevention and control programs. Results Our landscape-based models identified low elevation, rural villages surrounded by forest land cover, and located in drainage basins with variable wetness patterns as being associated with higher BU disease prevalence rates. We also identified five spatial disease clusters. Three of the five clusters contained villages with greater than expected prevalence rates and two clusters contained villages with lower than expected prevalence rates. Those villages with greater than expected BU disease prevalence rates spanned a fairly narrow region of south-central Benin. Conclusion Our analyses suggest that interactions between natural land cover and human alterations to the landscape likely play a role in the dynamics of BU disease. For example, urbanization

    Full Text Available Abstract Background Obstructive sleep apnea (OSA is a common disease, affecting approximately 2% of women and 4% of men residing in Western communities. No systematically reviewed data are available about the prevalence of this disease in Asia, the most heavily populated continent. Methods PubMed/Medline, Scopus and Google Scholar were searched for articles published from 1993 to May 2012 that reported the prevalence of OSA diagnosed via sleep monitoring and the prevalence of patients at risk for OSA as assessed by symptomatology and/or sleep questionnaires. We have also searched abstract database of major pulmonary and sleep scientific societies for relevant abstracts presented from 2010 to 2012. The following inclusion criteria were used: articles published in English, age ≥ 18 years, ≥ 100 participants in studies using sleep monitoring for the diagnosis of OSA, ≥ 300 participants in studies using questionnaires to detect patients at high risk for OSA. Exclusion criteria: duplicate publications, studies reporting the prevalence of central sleep apnea only, hospital based studies as well as studies assessing OSA prevalence among patients with resistant arterial hypertension, chronic kidney disease, heart failure and in patients with concomitant neurological disease. Results Twenty four articles were found to meet the inclusion criteria, covering 47,957 subjects (26,042 men and 21,915 women and four relevant abstracts were noted. OSA prevalence ranged from 3.7% to 97.3%. Male gender, older age, a higher BMI and waist to hip ratio, greater neck circumference, arterial hypertension, smoking, snoring and daytime sleepiness were associated with OSA. Sample size, difference between the populations studied and the fact that some works included patients with a high pre-test probability of OSA explain the difference in prevalence rates. Conclusion This systematic review highlights the lack of data regarding the prevalence of OSA in Asians

    Tokyo and its outlying cities are home to one-quarter of Japan's 127 million people. Highly destructive earthquakes struck the capital in 1703, 1855 and 1923, the last of which took 105 000 lives. Fuelled by greater Tokyo's rich seismological record, but challenged by its magnificent complexity, our joint Japanese-US group carried out a new study of the capital's earthquake hazards. We used the prehistoric record of great earthquakes preserved by uplifted marine terraces and tsunami deposits (17 M???8 shocks in the past 7000 years), a newly digitized dataset of historical shaking (10 000 observations in the past 400 years), the dense modern seismic network (300 000 earthquakes in the past 30 years), and Japan's GeoNet array (150 GPS vectors in the past 10 years) to reinterpret the tectonic structure, identify active faults and their slip rates and estimate their earthquake frequency. We propose that a dislodged fragment of the Pacific plate is jammed between the Pacific, Philippine Sea and Eurasian plates beneath the Kanto plain on which Tokyo sits. We suggest that the Kanto fragment controls much of Tokyo's seismic behaviour for large earthquakes, including the damaging 1855 M???7.3 Ansei-Edo shock. On the basis of the frequency of earthquakes beneath greater Tokyo, events with magnitude and location similar to the M??? 7.3 Ansei-Edo event have a ca 20% likelihood in an average 30 year period. In contrast, our renewal (time-dependent) probability for the great M??? 7.9 plate boundary shocks such as struck in 1923 and 1703 is 0.5% for the next 30 years, with a time-averaged 30 year probability of ca 10%. The resulting net likelihood for severe shaking (ca 0.9g peak ground acceleration (PGA)) in Tokyo, Kawasaki and Yokohama for the next 30 years is ca 30%. The long historical record in Kanto also affords a rare opportunity to calculate the probability of shaking in an alternative manner exclusively from intensity observations. This approach permits robust estimates

    Greater confinement disposal (GCO) has been defined by the National Low-Level Waste Program as the disposal of low-level waste in such a manner as to provide greater containment of radiation, reduce potential for migration or dispersion or radionuclides, and provide greater protection from inadvertent human and biological intrusions in order to protect the public health and safety. This paper discusses: the need for GCD; definition of GCD; advantages and disadvantages of GCD; relative dose impacts of GCD versus shallow land disposal; types of waste compatible with GCD; objectives of GCD borehole demonstration test; engineering and technical issues; and factors affecting performance of the greater confinement disposal facility

    Full Text Available Objectives: The study aimed to check the age- and gender-wise prevalence of oral habits in the children of 7–16-year-old Indian children. Materials and Methods: A cross-sectional survey involving 1029 (661 males and 368 females children of age 7–16 years was done to record the presence or absence of the oral habits with the aid of the anamnestic questionnaire. The recorded oral habits were tongue thrusting, thumb or digit sucking, mouth breathing, bruxism, lip biting or lip sucking, and nail biting. The collected data were subjected to Pearson's Chi-square statistical analysis to know the overall difference in the prevalence rate of different oral habits and to evaluate the gender- and age-wise difference in the prevalence of oral habits. Results: Oral habits were present in 594 participants (57.73%. The highest prevalence rate was registered for tongue thrusting habit (28.8%, which was followed by nail biting (201/19.5% and thumb sucking (128/12.4%, mouth breathing (109/10.6%, lip biting (85/8.3%, and bruxism (29/2.8%. The male participants showed a greater prevalence rate for the oral habits than the female participants (58.55% vs. 56.25%. There was a significant difference in the age-wise prevalence of oral habits with older children showing greater prevalence of oral habits than the younger ones. Conclusion: The prevalence of oral habits in the current group of children is high. It warrants the need for the community-based educational preventive and interceptive programs to spread the awareness regarding the deleterious effects of these oral habits.

    The jack jumper ant (Myrmecia pilosula) is responsible for greater than 90% of Australian ant venom allergy. However, deaths have only been recorded in the island of Tasmania. We sought to determine the prevalence, clinical features, natural history, and predictors of severity of M pilosula sting allergy in Tasmania. We performed a random telephone survey supported by serum venom-specific IgE analysis, review of emergency department presentations, and follow-up of allergic volunteers. M pilosula, honeybee (Apis mellifera), and yellow jacket wasp (Vespula germanica) sting allergy prevalences were 2.7%, 1.4%, and 0.6% compared with annual sting exposure rates of 12%, 7%, and 2%, respectively. Similarly, emergency department presentations with anaphylaxis to M pilosula were double those for honeybee. M pilosula allergy prevalence increased with age of 35 years or greater (odds ratio [OR], 2.4) and bee sting allergy (OR, 16.9). Patients 35 years of age or older had a greater risk of hypotensive reactions (OR, 2.9). Mueller reaction grades correlated well with adrenaline use. During follow-up, 79 (70%) of 113 jack jumper stings caused anaphylaxis. Prior worst reaction severity predicted the likelihood and severity of follow-up reactions; only 3 subjects had more severe reactions. Venom-specific IgE levels and other clinical features, including comorbidities, were not predictive of severity. Sting allergy prevalence is determined by age and exposure rate. M pilosula sting exposure in Tasmania is excessive compared with that found in mainland Australia, and there is a high systemic reaction risk in allergic people on re-sting. Prior worst reaction severity (Mueller grade) and age predict reaction severity and might be used to guide management.

    Our aim was to examine lifetime criteria profiles and correlates of severity (mild, moderate, severe) of DSM-5 alcohol use disorders (AUD) in Puerto Rico. Data are from a household random sample of individuals 18 to 64 years of age in San Juan, Puerto Rico. The survey response rate was 83%. DSM-5 AUD was identified with the Spanish version of the World Health Organization's Composite International Diagnostic Interview. The analyses also identify correlates of each severity level using an ordered logistic regression model. The prevalence of lifetime DSM-5 AUD among men and women was 38 and 16%, respectively. Mild lifetime DSM-5 AUD was the most prevalent severity level among both men (18%) and women (9%). The most common criteria, independent of gender and severity level, were drinking larger quantities and for longer than planned (men range: 80 to 97%; women range: 78 to 91%) and hazardous use (men range: 56 to 91%; women range: 42 to 74%). Results from ordered logistic regression showed that the adjusted odds ratio for weekly drinking frequency, greater volume of alcohol consumed per drinking occasion, positive attitudes about drinking, drinking norms, and male gender invariantly increased risks across all DSM-5 AUD severity levels (mild, moderate, severe). Greater negative attitudes about drinking, low family cohesion, and Protestant religion were related to greater risks at higher AUD severity levels. AUD prevalence is high in San Juan, Puerto Rico. Prevalence rates for some criteria are equally high across severity levels and poorly differentiate between mild, moderate, or severe DSM-5 AUD. The sociodemographic and alcohol-related risks vary across DSM-5 severity levels. Copyright © 2018 by the Research Society on Alcoholism.

  16. Timing is everything: international variations in historical sexual partnership concurrency and HIV prevalence.

    Directory of Open Access Journals (Sweden)

    Martina Morris

    Full Text Available BACKGROUND: Higher prevalence of concurrent partnerships is one hypothesis for the severity of the HIV epidemic in the countries of Southern Africa. But measures of the prevalence of concurrency alone do not adequately capture the impact concurrency will have on transmission dynamics. The importance of overlap duration and coital exposure are examined here. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a comparison of data from three studies of sexual behavior carried out in the early 1990s in Uganda, Thailand and the US. Using cumulative concurrency measures, the three countries appeared somewhat similar. Over 50% of both Thai and Ugandan men reported a concurrency within the last three partnerships and over 20% reported a concurrency in the last year, the corresponding rates among US men were nearly 20% for Blacks and Hispanics, and about 10% for other racial/ethnic groups. Concurrency measures that were more sensitive to overlap duration, however, showed large differences. The point prevalence of concurrency on the day of interview was over 10% among Ugandan men compared to 1% for Thai men. Ugandan concurrencies were much longer duration - a median of about two years - than either the Thai (1 day or US concurrencies (4-9 months across all groups, and involved 5-10 times more coital risk exposure with the less frequent partner. In the US, Blacks and Hispanics reported higher prevalence, longer duration and greater coital exposure than Whites, but were lower than Ugandans on nearly every measure. Together, the differences in the prevalence, duration and coital exposure of concurrent partnerships observed align with the HIV prevalence differentials seen in these populations at the time the data were collected. CONCLUSIONS/SIGNIFICANCE: There were substantial variations in the patterns of concurrent partnerships within and between populations. More long-term overlapping partnerships, with regular coital exposure, were found in populations with

    Key in understanding the geodynamics governing subduction and orogeny is reconstructing the paleogeography of `Greater India', the Indian plate lithosphere that subducted since Tibetan Himalayan continental crustal collision with Asia. Here, we discuss how the principle of Ockham's Razor, favoring the simplest scenario as the most likely, may apply to three perspectives on Greater India's paleogeography. We follow recent constraints suggesting a 58 Ma initial collision and update the kinematic restoration of intra-Asian shortening with a recently proposed Indochina extrusion model that reconciles long-debated large and small estimates of Indochina extrusion. The reconstruction is tested against Tibetan paleomagnetic rotation data, and against seismic tomographic constraints on paleo-subduction zone locations. The resulting restoration shows 1000-1200 km of post-collisional intra-Asian shortening, leaving a 2600-3400 km wide Greater India. Ockham's Razor from a paleogeographic, sediment provenance perspective would prefer a fully continental Greater India, although these sediments may also source from the Paleocene-Eocene west Indian orogen unrelated to the India-Asia collision. Ockham's Razor applied from a kinematic, paleomagnetic perspective, prefers major Cretaceous extension and `Greater India Basin' opening within Greater India, but data uncertainty may speculatively allow for minimal extension. Finally, from a geodynamic perspective, assuming a fully continental Greater India would require that the highest subduction rates recorded in the Phanerozoic would have been driven by a subduction of a lithosphere-crust assemblage more buoyant than the mantle, which seems physically improbable. Ockhams Razor thereby isolates the Greater India Basin hypothesis as the only scenario sustainable from all perspectives. Finally, we infer that the old pre-collisional lithosphere rapidly entered the lower mantle sustaining high subduction rates, whilst post

    Expending effort is generally considered to be undesirable. However, both humans and vertebrates will work for a reward they could also get for free. Moreover, cues associated with high-effort rewards are preferred to low-effort associated cues. Many explanations for these counterintuitive findings have been suggested, including cognitive dissonance (self-justification) or a greater contrast in state (e.g., energy or frustration level) before and after an effort-linked reward. Here, we test whether effort expenditure also increases perceived value in ants, using both classical cue-association methods and pheromone deposition, which correlates with perceived value. In 2 separate experimental setups, we show that pheromone deposition is higher toward the reward that requires more effort: 47% more pheromone deposition was performed for rewards reached via a vertical runway (high effort) compared with ones reached via a horizontal runway (low effort), and deposition rates were 28% higher on rough (high effort) versus smooth (low effort) runways. Using traditional cue-association methods, 63% of ants trained on different surface roughness, and 70% of ants trained on different runway elevations, preferred the high-effort related cues on a Y maze. Finally, pheromone deposition to feeders requiring memorization of one path bifurcation was up to 29% higher than to an identical feeder requiring no learning. Our results suggest that effort affects value perception in ants. This effect may stem from a cognitive process, which monitors the change in a generalized hedonic state before and after reward.

    Gas, oil, and water production data were compiled from selected wells in four gas fields in rocks of Late Cretaceous age in southwestern Wyoming. This study is one of a series of reports examining fluid production from tight-gas reservoirs, which are characterized by low permeability, low porosity, and the presence of clay minerals in pore space. Production from each well is represented by two samples spaced five years apart, the first sample typically taken two years after commencement of production. For each producing interval, summary diagrams of oil versus gas and water versus gas production show fluid production rates, the change in rates during five years, the water-gas and oil-gas ratios, and the fluid type. These diagrams permit well-to-well and field-to-field comparisons. Fields producing water at low rates (water dissolved in gas in the reservoir) can be distinguished from fields producing water at moderate or high rates, and the water-gas ratios are quantified. The ranges of first-sample gas rates in Pinedale field and Jonah field are quite similar, and the average gas production rate for the second sample, taken five years later, is about one-half that of the first sample for both fields. Water rates are generally substantially higher in Pinedale than in Jonah, and water-gas ratios in Pinedale are roughly a factor of ten greater in Pinedale than in Jonah. Gas and water production rates from each field are fairly well grouped, indicating that Pinedale and Jonah fields are fairly cohesive gas-water systems. Pinedale field appears to be remarkably uniform in its flow behavior with time. Jonah field, which is internally faulted, exhibits a small spread in first-sample production rates. In the Greater Wamsutter field, gas production from the upper part of the Almond Formation is greater than from the main part of the Almond. Some wells in the main and the combined (upper and main parts) Almond show increases in water production with time, whereas increases

    The aim of this study was to determine the prevalence of Molar-Incisor Hypomineralisation (MIH) in Wainuiomata children and describe differences in prevalence among Māori, Pacific Island and New Zealand European ethnic groups. Cross-sectional survey of developmental defects of enamel in a random sample of children attending primary school in Wainuiomata, Wellington. Study information and consent forms were sent to 850 7-to-10-year-old schoolchildren. Using the modified Developmental Defects of Enamel index, a single paediatric dentist examined students in the classroom. Dental caries experience was recorded as decayed, missing or filled primary and permanent teeth. Examinations were conducted on 522 children (participation rate 61.4%). The mean age of the children was 8.2 years (range 7 to 10 years). MIH prevalence was 14.9%. The prevalence ofhypomineralisation ofany tooth was 15.3%, and that for hypoplasia was 4.0%. There was no statistically significant ethnic difference in MIH prevalence. The mean DMFT was 0.16 (SD, 0.54) in those without a developmental defect, 0.54 (SD, 1.12) in those with hypomineralisation and 1.85 (SD, 1.85) in those with hypoplasia (p MIH. Ethnicity is not a modifying factor in the occurrence of developmental defects of enamel. The presence of hypomineralisation and/or hypoplasia was associated with significantly greater caries experience in the permanent dentition.

    Full Text Available Background: The relationship between breastfeeding and postpartum depression is bidirectional. Breastfeeding improves the maternal and neonatal health. There is now growing evidence that it might play a role in the prevention of postpartum depression. Objective: This study explores the relationship between breastfeeding and maternal postpartum depression. It also estimates the prevalence rate of postpartum depression among Saudi women. Methods: This is a cross-sectional study. Three-hundred postpartum women were recruited for this study from various hospitals in the Eastern Province of Saudi Arabia. Likelihood of depression was assessed using the Edinburgh Postpartum Depression Scale (EPDS. Socio-demographic data were collected as well as data regarding breastfeeding duration and intention to breastfeed. Data analysis was done using SPSS version 21, using parametric tests; independent t-test and One-Way ANOVA. Results: Postpartum mothers who intended to breast-feed their babies had a lower EPDS scores compared with those who did not intend to breast-feed. No correlation was found between the duration of breastfeeding and EPDS scores. Prevalence rate of postpartum depression in our sample was 14%. Greater age, having previous babies, intention to breastfeed and vaginal delivery were significantly associated with actual breastfeeding. Conclusion: Screening for mothers in the early postpartum period is essential to detect those who are at risk for postpartum depression. Breastfeeding may help to reduce and prevent the appearance of symptoms of depression. Prevalence rate of postpartum depression in Saudi Arabia, 14%, is similar to the worldwide rate.

    Women have consistently higher prevalence rates of anxiety disorders, but less is known about how gender affects age of onset, chronicity, comorbidity, and burden of illness. Gender differences in DSM-IV anxiety disorders were examined in a large sample of adults (N = 20,013) in the United States using data from the Collaborative Psychiatric Epidemiology Studies (CPES). The lifetime and 12-month male:female prevalence ratios of any anxiety disorder were 1:1.7 and 1:1.79, respectively. Women had higher rates of lifetime diagnosis for each of the anxiety disorders examined, except for social anxiety disorder which showed no gender difference in prevalence. No gender differences were observed in the age of onset and chronicity of the illness. However, women with a lifetime diagnosis of an anxiety disorder were more likely than men to also be diagnosed with another anxiety disorder, bulimia nervosa, and major depressive disorder. Furthermore, anxiety disorders were associated with a greater illness burden in women than in men, particularly among European American women and to some extend also among Hispanic women. These results suggest that anxiety disorders are not only more prevalent but also more disabling in women than in men. PMID:21439576

    This study investigates the prevalence of asthma and asthma-related symptoms in New Orleans inner-city schoolchildren. A cross-sectional survey of 1535 elementary, middle, and high school children (aged 5-18) was conducted by using the International Study of Asthma and Allergies in Childhood (ISAAC) written questionnaire. Lifetime prevalence of wheezing was 39.4%, and lifetime prevalence of asthma was 24.4%. Wheezing during the previous 12 months was reported by 25.7% of the sample. Twenty-one percent of respondents reported having one or more attacks of wheezing per year, with 5.6% reporting four or more attacks per year. Many participants reported sleep disturbance (15.4%), with 6.2% reporting sleep disturbance more than once a week. The 12-month rate of speech limitation due to asthma exacerbation was 6.6%. Exercise-induced asthma was reported by 16.9% of the students, and nocturnal cough (not associated with cold) was reported by 27.3%. Overall, boys reported higher rates of symptoms than girls, and younger children (aged 6-7) reported greater symptoms than older children (aged 13-14). These findings show that prevalence of asthma in this population is elevated, and the ISAAC written questionnaire successfully identified inner-city children at risk for asthma in New Orleans.

    The 2008 World Health Organization (WHO) criteria were used to identify 88 consecutive Mayo Clinic patients with ‘myelodysplastic syndrome with isolated del(5q)' (median age 74 years; 60 females). In all, 60 (68%) patients were followed up to the time of their death. Overall median survival was 66 months; leukemic transformation was documented in five (5.7%) cases. Multivariable analysis identified age ⩾70 years (P=0.01), transfusion need at diagnosis (P=0.04) and dysgranulopoiesis (P=0.02) as independent predictors of shortened survival; the presence of zero (low risk), one (intermediate risk) or ⩾2 (high risk) risk factors corresponded to median survivals of 102, 52 and 27 months, respectively. Janus kinase 2 (JAK2), thrombopoietin receptor (MPL), isocitrate dehydrogenase 1 (IDH1) and IDH2 mutational analysis was performed on archived bone marrows in 78 patients; JAK2V617F and MPLW515L mutations were shown in five (6.4%) and three (3.8%) patients, respectively, and did not seem to affect phenotype or prognosis. IDH mutations were not detected. Survival was not affected by serum ferritin and there were no instances of death directly related to iron overload. The current study is unique in its strict adherence to WHO criteria for selecting study patients and providing information on long-term survival, practical prognostic factors, baseline risk of leukemic transformation and the prevalence of JAK2, MPL and IDH mutations.

    Antimicrobial resistance genes can be found in all ecosystems, including those where antibiotic selective pressure has never been exerted. We investigated resistance genes in a collection of faecal samples of wildlife (non-human primates, mice), people and domestic animals (dogs, cats) in Côte d'Ivoire; in the chimpanzee research area of Taï National Park (TNP) and adjacent villages. Single bacteria isolates were collected from antibiotic-containing agar plates and subjected to molecular analysis to detect Enterobacteriaceae isolates with plasmid-mediated genes of extended-spectrum beta-lactamases (ESBLs) and plasmid-mediated quinolone resistance (PMQR). While the prevalence of ESBL-producing E. coli in the villages was 27% in people (n = 77) and 32% in dogs (n = 38), no ESBL-producer was found in wildlife of TNP (n = 75). PMQR genes, mainly represented by qnrS1, were also present in human- and dog-originating isolates from the villages (36% and 42% in people and dogs, respectively), but no qnrS has been found in the park. In TNP, different variants of qnrB were detected in Citrobacter freundii isolates originating non-human primates and mice. In conclusion, ESBL and PMQR genes frequently found in humans and domestic animals in the villages were rather exceptional in wildlife living in the protected area. Although people enter the park, the strict biosecurity levels they are obliged to follow probably impede transmission of bacteria between them and wildlife.

    We studied the incidence of greater trochanteric fractures at our department following THR. In all we examined 911 patients retrospectively and found the occurance of a greater trochanteric fracture to be 3%. Patients with fractures had significantly poorer outcome on Oxford Hip score, Pain VAS, Satisfaction VAS and EQ-5D compared to THR without fractures. Greater trochanteric fracture following THR is one of the most common complications following THR. It has previously been thought to have little impact on the overall outcome following THR, but our study suggests otherwise.

    The prevalence of obesity and diabetes mellitus (DM) has increased worldwide. Our objective was to examine trends in the prevalence of overweight, obesity, morbid obesity and DM in Spain from 1987 to 2012. Data were obtained from 8 waves of the national health surveys which are cross-sectional studies conducted in representative samples of the Spanish adult population. Self-reported data of 156,440 adults (≥16 years) from 1987 to 2012 were used. Body mass index (BMI) was calculated from self-reported weight and height. Overweight was defined as a BMI of 25.0 to 29.9kg/m 2 , obesity as a BMI≥30kg/m 2 and morbid obesity as a BMI≥40kg/m 2 . DM was considered present if the participant reported having been diagnosed. Age-adjusted prevalence was adjusted by the direct standardisation method to the 2003 survey population. From 1987 to 2012 age-adjusted prevalence of overweight increased from 34.0% (95% confidence interval [95% CI] 33.2-34.8) to 35.8% (95% CI 35.0-36.6), prevalence of obesity from 8.0% (95% CI 7.5-8.5) to 16.5% (95% CI 15.7-17.1%) and DM prevalence from 4.2% (95% CI 3.9-4.5) to 7.1% (95% CI 6.7-7.4%). Morbid obesity increased from 0.20% (95% CI 0.13-0.27) in 1993 to 0.88% (95% CI 0.70-1.05) in 2012. The growth rate was greater among males. An increasing trend of the prevalence of overweight, obesity, morbid obesity and DM was found in Spain from 1987 to 2012, particularly in males. Copyright © 2016 Elsevier España, S.L.U.

    Socio-economic considerations of better air quality on the Greater Vancouver population and economy were discussed. The purpose of the study was to provide socio-economic information to staff and stakeholders of the Greater Vancouver Regional District (GVRD) who are participating in an Air Quality Management Plan (AQMP) development process and the Sustainable Region Initiative (SRI) process. The study incorporated the following methodologies: identification and review of Canadian, American, and European quantitative socio-economic, cost-benefit, cost effectiveness, competitiveness and health analyses of changes in air quality and measures to improve air quality; interviews with industry representatives in Greater Vancouver on competitiveness impacts of air quality changes and ways to improve air quality; and a qualitative analysis and discussion of secondary quantitative information that identifies and evaluates socio-economic impacts arising from changes in Greater Vancouver air quality. The study concluded that for the Greater Vancouver area, the qualitative analysis of an improvement in Greater Vancouver air quality shows positive socio-economic outcomes, as high positive economic efficiency impacts are expected along with good social quality of life impacts. 149 refs., 30 tabs., 6 appendices

  5. A Data-Driven Evaluation of the Stop TB Global Partnership Strategy of Targeting Key Populations at Greater Risk for Tuberculosis.

    Directory of Open Access Journals (Sweden)

    Zoë M McLaren

    Full Text Available Identifying those infected with tuberculosis (TB is an important component of any strategy for reducing TB transmission and population prevalence. The Stop TB Global Partnership recently launched an initiative with a focus on key populations at greater risk for TB infection or poor clinical outcomes, due to housing and working conditions, incarceration, low household income, malnutrition, co-morbidities, exposure to tobacco and silica dust, or barriers to accessing medical care. To achieve operational targets, the global health community needs effective, low cost, and large-scale strategies for identifying key populations. Using South Africa as a test case, we assess the feasibility and effectiveness of targeting active case finding to populations with TB risk factors identified from regularly collected sources of data. Our approach is applicable to all countries with TB testing and census data. It allows countries to tailor their outreach activities to the particular risk factors of greatest significance in their national context.We use a national database of TB test results to estimate municipality-level TB infection prevalence, and link it to Census data to measure population risk factors for TB including rates of urban households, informal settlements, household income, unemployment, and mobile phone ownership. To examine the relationship between TB prevalence and risk factors, we perform linear regression analysis and plot the set of population characteristics against TB prevalence and TB testing rate by municipality. We overlay lines of best fit and smoothed curves of best fit from locally weighted scatter plot smoothing.Higher TB prevalence is statistically significantly associated with more urban municipalities (slope coefficient β1 = 0.129, p < 0.0001, R2 = 0.133, lower mobile phone access (β1 = -0.053, p < 0.001, R2 = 0.089, lower unemployment rates (β1 = -0.020, p = 0.003, R2 = 0.048, and a lower proportion of low-income households

    The scale at which analyses are performed can have an effect on model results and often one scale does not accurately describe the ecological phenomena of interest (e.g., population trends) for wide-ranging species: yet, most ecological studies are performed at a single, arbitrary scale. To best determine local and regional trends for greater sage-grouse (Centrocercus urophasianus) in Wyoming, USA, we modeled density-independent and -dependent population growth across multiple spatial scales relevant to management and conservation (Core Areas [habitat encompassing approximately 83% of the sage-grouse population on ∼24% of surface area in Wyoming], local Working Groups [7 regional areas for which groups of local experts are tasked with implementing Wyoming's statewide sage-grouse conservation plan at the local level], Core Area status (Core Area vs. Non-Core Area) by Working Groups, and Core Areas by Working Groups). Our goal was to determine the influence of fine-scale population trends (Core Areas) on larger-scale populations (Working Group Areas). We modeled the natural log of change in population size ( peak M lek counts) by time to calculate the finite rate of population growth (λ) for each population of interest from 1993 to 2015. We found that in general when Core Area status (Core Area vs. Non-Core Area) was investigated by Working Group Area, the 2 populations trended similarly and agreed with the overall trend of the Working Group Area. However, at the finer scale where Core Areas were analyzed separately, Core Areas within the same Working Group Area often trended differently and a few large Core Areas could influence the overall Working Group Area trend and mask trends occurring in smaller Core Areas. Relatively close fine-scale populations of sage-grouse can trend differently, indicating that large-scale trends may not accurately depict what is occurring across the landscape (e.g., local effects of gas and oil fields may be masked by increasing

    The purpose of this research study was to determine the factors influencing peripheral phlebitis in the adult medical-surgical population. The authors would then be able to use those data to determine whether a change in practice was warranted. Data collection and analysis of 188 intravenous sites revealed that females with higher doses of medications in intravenous sites of longer dwell times and suboptimal nutrition were at greater risk of developing peripheral phlebitis. The point prevalence was greater than the recommended 5%, which led the authors to review their facility's patient care and documentation practices.

  9. What Is the Economic Cost of Unplanned Pregnancy Following Hysteroscopic Sterilization in the US? A New National Estimate Based on Essure® Procedure Prevalence, Failure Rates and Workforce Productivity.

    Science.gov (United States)

    Sills, E Scott; Fernandez, Luca P; Jones, Christopher A

    Although hysteroscopic sterilization (HS) (Essure ®) has been available in the US since 2002, there is disagreement regarding its efficacy, and there has been no study of the economic impact of HS failure. Our investigation examined the economic consequences of contraceptive failure with Essure in the US. Contraceptive failure rates (CFR) of 5.7%, 7.7% and 9.6% were applied to the US cohort of HS patients (n = 600,000). Direct economic impact of productivity losses resulting from unplanned conceptions after HS was calculated by factoring Essure failure rate, the exposed population, US female labour force participation, unemployment rate, time away from work owing to vaginal delivery or pregnancy termination and weekly wages. For the 9.6% CFR scenario, US workforce productivity loss from unplanned pregnancy and delivery was estimated at 771,065 days (2,112 years). Productivity loss secondary to conception and subsequent termination of pregnancy after Essure was approximately 23,725 days (65 years). Assuming CFR at 5.7%, livebirth delivery with total time missed from work at 65 days, this was associated with an aggregate economic impact of $49.2M in lost annual wages. Direct economic impact of unplanned pregnancy after Essure irrespective of outcome (terminations and deliveries) was estimated to result in US productivity losses valued at ~$130M. Although not all unplanned pregnancy costs are attributable to failed HS, estimates derived from earlier surveys have not considered this contraceptive method, and the economic consequences of unplanned pregnancy after Essure are not trivial. Quantifying the economic consequences of HS failure would be improved with specific ICD-10 coding for Essure-associated symptoms.

    We present and interpret newly determined site motions derived from GPS observations made from 2008 through 2016 in the Republic of Georgia, which constrain the rate and locus of active shortening in the Lesser-Greater Caucasus continental collision zone. Observation sites are located along two ∼160 km-long profiles crossing the Lesser-Greater Caucasus boundary zone: one crossing the Rioni Basin in western Georgia and the other crossing further east near the longitude of Tbilisi. Convergence across the Rioni Basin Profile occurs along the southern margin of the Greater Caucasus, near the surface trace of the north-dipping Main Caucasus Thrust Fault (MCTF) system, and is consistent with strain accumulation on the fault that generated the 1991 MW6.9 Racha earthquake. In contrast, convergence along the Tbilisi Profile occurs near Tbilisi and the northern boundary of the Lesser Caucasus (near the south-dipping Lesser Caucasus Thrust Fault), approximately 50-70 km south of the MCTF, which is inactive within the resolution of geodetic observations (< ± 0.5 mm/yr) at the location of the Tbilisi Profile. We suggest that the southward offset of convergence along strike of the range is related to the incipient collision of the Lesser-Greater Caucasus, and closing of the intervening Kura Basin, which is most advanced along this segment of the collision zone. The identification of active shortening near Tbilisi requires a reevaluation of seismic hazards in this area.

    To determine the prevalence of temporary social security benefits due to respiratory disease granted to employees, as well as the number of lost workdays and costs resulting from those in Brazil between 2003 and 2004. Cross-sectional study using data obtained from the Unified System of Benefits of the Brazilian Institute of Social Security (INSS, Instituto Nacional de Seguro Social) and the Brazilian Social Registry Database. Data regarding gender, age, diagnosis and type of economic activity, as well as type, duration and cost of benefits, were compiled. Respiratory diseases accounted for 1.3% of the total number of temporary social security benefits granted by INSS, with a prevalence rate of 9.92 (per 10,000 employment contracts). Females and individuals older than 50 years of age were the most affected. Non-work-related benefits were more common than were work-related benefits. The most prevalent diseases were pneumonia, asthma and COPD, followed by laryngeal and vocal cord diseases. The most prevalent types of economic activity were auxiliary transportation equipment manufacturing, tobacco product manufacturing and computer-related activities. The mean duration of benefits was 209.68 days, with a mean cost of R$ 4,495.30 per occurrence. Respiratory diseases caused by exogenous agents demanded longer sick leave (mean, 296.72 days) and greater cost (mean, R$ 7,105.74). The most prevalent diseases were airway diseases and pneumonia. Workers from auxiliary transportation equipment manufacturing, tobacco product manufacturing and computer-related activities were the most affected. Diseases caused by exogenous agents demanded longer sick leaves and resulted in greater costs.

    1978-01-01

    The prevalence of stuttering in a university population was 2.1%; 3.4% were former stutterers. More men than women stuttered. Right handed female stutterers were less likely to have "lost" their stutter than were right handed males. Stutterers, past stutterers, and questionable stutterers all had a family history of stuttering. The significant prevalence of stuttering, the increased prevalence among males, the lack of a decline of this disorder over the past few decades despite the increased number of speech clinicians and data concerning handedness, emphasise the need to investigate organic causes of stuttering.

    Parasites of wildlife inhabiting urbanised and peri-urban environments are of interest regarding wildlife population health, and also veterinary public health in the case of parasites that can also infect humans and domestic animals. This study aimed to: identify, and estimate the prevalence of, species of Eimeria parasitic in quenda (Isoodon obesulus) in the greater Perth region, Western Australia; 2) morphologically describe and genetically characterise a novel observed species of Eimeria as E. angustus; and 3) genetically characterise E. kanyana. Eimeria spp. prevalence was 76.1% (95% CI 64.9-84.5%), and four putative species of Eimeria were identified. Eimeria kanyana was identified infecting quenda for the first time, with a prevalence of 54.9% (43.4-66.0%). Eimeria quenda was less prevalent, at 7.0% (3.1-15.5%). The novel species E. angustus was present in 45.1% of sampled quenda (34.0-56.6%). A second novel morphotype of Eimeria was present in 2.8% of sampled quenda (0.9-9.7%). Mixed Eimeria spp. infections were present in 21/71 quenda (29.6%, 95% CI 20.2-41.1%). Molecular phylogenetic analyses of E. kanyana and E. angustus were conducted at the 18S rRNA and mitochondrial cytochrome oxidase loci. At both loci, two isolates identified as E. kanyana grouped in a phylogenetic clade with E. trichosuri. Five isolates identified as the novel E. angustus were most closely related to E. tropidura at the 18S locus. At the COI locus, no sequence data were available for E. tropidura; isolates of E. angustus grouped with E. sciurorum. Copyright © 2016 Elsevier Inc. All rights reserved.

    Higher-tier environmental risk assessments on 'down-the-drain' chemicals in river networks can be conducted using models such as GREAT-ER (Geography-referenced Regional Exposure Assessment Tool for European Rivers). It is important these models are evaluated and their sensitivities to input variables understood. This study had two primary objectives: evaluate GREAT-ER model performance, comparing simulated modelled predictions for LAS (linear alkylbenzene sulphonate) with measured concentrations, for four rivers in the UK, and investigate model sensitivity to input variables. We demonstrate that the GREAT-ER model is very sensitive to variability in river discharges. However it is insensitive to the form of distributions used to describe chemical usage and removal rate in sewage treatment plants (STPs). It is concluded that more effort should be directed towards improving empirical estimates of effluent load and reducing uncertainty associated with usage and removal rates in STPs. Simulations could be improved by incorporating the effect of river depth on dissipation rates. - Validation of GREAT-ER.

    Full Text Available Introduction: Hypertension in pregnancy is one of the three factors of maternal mortality. Etiology of the disease is unknown, but the many factors contributing to the identification and control of it can be taken a step to prevent and reduce the symptoms of the disease. The purpose of this study was to determine the prevalence of preeclampsia (high-blood pressure in different seasons of the year. Methods: The present retrospective cross-sectional study was conducted on more than 8,000 pregnant women visiting Assali specialized hospital from 2011 to 2013. Required data was collected through questionnaire checklist. The Chi-square test with multiple comparisons was used to compare the frequencies of pregnancy-induced hypertension (PIH according to the month of year, and adjustment of multiplicity was conducted using Bonferroni's method. Student's t-test was used to compare the means of PIH prevalence rates. In all analyses, P < 0.05 was taken to indicate statistical significance. Results: In these 8000 woman admitted to labor, overall prevalence of PIH was 3.8 ± 0.6%. The prevalence rate of PIH was highest in the summer (4.5% and lowest frequent in the winter (2.7%, respectively. In July, the prevalence rate was significantly higher than those for any other month (4.7%, and in March, it was lower prevalence than for any month (2.2%, respectively. Using the Chi-square test, a significant difference between the incidence of disease was observed in summer and winter (P < 0.001. Conclusion: The prevalence rate of PIH was higher for delivery in summer and early spring and lowest for winter delivery among Khorramabad women based on these results; it seems that changes in temperature and humidity in different seasons can affect preeclampsia, and preeclampsia increases with increasing frequency temperature.

    To evaluate, if possible, the radiographic features of tuberculous osteitis in the greater trochanter and ischium, and to determine the cause of the lesions. We reterospectively reviewed the plain radiographic findings of 14 ptients with histologically proven tuberculous osteitis involving the greater trochanter and ischium. In each case, the following were analyzed:morphology of bone destruction, including cortical erosion;periosteal reaction;presence or abscence of calcific shadows in adjacent soft tissue. On the basis of an analysis of radiographic features and correlation of the anatomy with adjacent structures we attempted to determine causes. Of the 14 cases evaluated, 12 showed varrious degrees of extrinsic erosion on the outer cortical bone of the greater trochanter and ischium ; in two cases, bone destruction was so severe that the radiographic features of advanced perforated osteomyelitis were simulated. In addition to findings of bone destruction, in these twelve cases, the presence of sequestrum or calcific shadows was seen in adjacent soft tissue. Tuberculous osteitis in the greater trochanter and ischium showed the characteristic findings of chronic extrinsic erosion. On the basis of these findings we can suggest that these lesions result from an extrinsic pathophysiologic cause such as adjacent bursitis

  13. Comparison of Prevalence- and Smoking Impact Ratio-Based Methods of Estimating Smoking-Attributable Fractions of Deaths

    Directory of Open Access Journals (Sweden)

    Kyoung Ae Kong

    2016-04-01

    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.

    This study sought to determine the prevalence of developmental defects of enamel (DDE) among preschool children and investigate associations with sociodemographic and socioeconomic factors and weight status. A cross-sectional study was conducted with 118 children aged 3 to 5 years. Data were collected via clinical examinations and a self-administered questionnaire completed by the parents. The diagnosis of DDE was performed using the modified DDE Index. Information on socioeconomic indicators (mother's schooling, monthly income per capita), child's sex and age, and age of mother at the birth of the child were obtained by questionnaire. The children's weight status was determined based on weight-for-age at the time of the exam. Statistical analysis involved the chi-squared test and Poisson regression with robust variance. The prevalence of DDE was 50.0%. DDE were more frequent in males (p = 0.025) and children whose families were classified as being at poverty line (p = 0.040). In the Poisson model controlled for child's sex and mother's schooling, children whose families were classified as being at the poverty line had a greater prevalence rate of DDE. In conclusion, the prevalence of DDE was high in the present sample and associated with lower household income. Weight status was not associated with DDE.

    Prolonged sitting is detrimentally associated with health outcomes. However, the prevalence and characteristics of those who sit in cars for long periods are not well understood. This study examined the population prevalence, socio-demographic variations, and trends for prolonged sitting in cars among adults. Using the Sydney Greater Metropolitan Area Household Travel Survey, the prevalence of prolonged sitting time in cars (≥2 h/day) was calculated for four 3-year periods (1997-99, 2000-02, 2003-05, and 2006-08) for each population subgroup. Trends were calculated as the mean change in prevalence between adjacent survey periods. Cars were used for 66% of the total trips recorded (n=336,505). The prevalence of prolonged sitting time in cars was 16-18% in men, and 10-12% in women. Relatively higher prevalence rates were found among middle-age groups (men: 20-22%, women: 12-15%), full-time workers (men: 21-24%, women: 14-15%), those with higher income (men: 21-25%, women: 14-16%), couples with children (men: 20-21%, women: 12-14%), and those living in outer suburbs (men: 20-23%, women: 12-13%). Trends were stable in men, but increasing in women. Several subgroups (older age; living in regional suburbs) also showed increasing trends. These findings provide evidence to inform integrated approaches to measurement and policy development on prolonged car use among the public health, urban planning, and transport sectors.

    To examine the prevalence, incidence and risk factors associated with visual hallucinations (VHs) amongst people suffering from Parkinson's disease (PD). We recruited 513 patients with PD from movement disorder and PD clinics within three sites in the UK. Patients were interviewed using a series of standardised clinical rating scales at baseline, 12, 24 and 36 months. Data relating to VHs were collected using the North-East Visual Hallucinations Interview. Prevalence rates for VHs at each assessment were recorded. Associations were determined using multiple regression analysis. Cross-sectional prevalence rates for VHs at baseline, 12, 24 and 36 months indicated VHs in approximately 50% of patients. A cumulative frequency of 82.7% of cases at the end of the study period exhibited VHs. The incidence rate for VHs was 457 cases per 1000 population. Longer disease duration, greater impairment in activities of daily living and higher rates of anxiety were most commonly associated with VHs. No factors predictive of VHs could be ascertained. When examined longitudinally, VHs affect more patients than is commonly assumed in cross-sectional prevalence studies. Clinicians should routinely screen for VHs throughout the disease course. Disease duration, impairment in activities of daily living and anxiety presented as co-morbidities associated with VHs in PD, and therefore those presenting with VHs should be screened for anxiety disorder and vice versa.

  17. Higher motivation - greater control? The effect of arousal on judgement.

    Riemer, Hila; Viswanathan, Madhu

    2013-01-01

    This research examines control over the effect of arousal, a dimension of affect, on judgement. Past research shows that high processing motivation enhances control over the effects of affect on judgement. Isolating and studying arousal as opposed to valence, the other dimension of affect, and its effect on judgement, we identify boundary conditions for past findings. Drawing from the literature on processes by which arousal influences judgement, we demonstrate that the role of motivation is contingent upon the type of judgement task (i.e., memory- versus stimulus-based judgement). In stimulus-based judgement, individuals exert greater control over the effect of arousal on judgement under low compared to high motivation. In contrast, in memory-based judgement individuals exert greater control over the effect of arousal under high compared to low motivation. Theoretical implications and avenues for future research are discussed.

    We examined the relationship between patient expectations of total joint arthroplasty and functional outcomes. We surveyed 1799 patients undergoing primary hip or knee arthroplasty for demographic data and Western Ontario McMaster University Osteoarthritis Index scores at baseline, 3 months, and 1 year of follow-up. Patient expectations were determined with 3 survey questions. The patients with the greatest expectations of surgery were younger, male, and had a lower body mass index. Linear regression modeling showed that a greater expectation of pain relief with surgery independently predicted greater reported pain relief at 1 year of follow-up, adjusted for all relevant covariates (P relief after joint arthroplasty is an important predictor of outcomes at 1 year.

Sex differences were also observed in associated symptomology, aura, headache-related disability, healthcare resource utilization, and diagnosis for migraine and PM. Despite higher rates of migraine diagnosis by a healthcare professional, females with migraine were less likely than males to be using preventive pharmacologic treatment for headache. In this large, US population sample, both migraine and PM were more common among females, but a sex difference was not observed in the prevalence of other severe headache. The sex difference in migraine and PM held true across age and for most other sociodemographic variables with the exception of race for PM. Females with migraine and PM had higher rates of most migraine symptoms, aura, greater associated impairment, and higher healthcare resource utilization than males. Corresponding sex differences were not observed among individuals with other severe headache on the majority of these comparisons. Results suggest that PM is part of the migraine spectrum whereas other severe headache types are not. Results also substantiate existing literature on sex differences in primary headaches and extend results to additional headache types and related factors. © 2013 American Headache Society.

    Vagal tone is widely believed to be an important physiological aspect of emotion regulation and associated positive behaviors. However, there is inconsistent evidence for relations between children’s baseline vagal tone and their helpful or prosocial responses to others (Hastings & Miller, 2014). Recent work in adults suggests a quadratic association (inverted U-shape curve) between baseline vagal tone and prosociality (Kogan et al., 2014). The present research examined whether this nonlinear association was evident in children. We found consistent evidence for a quadratic relation between vagal tone and prosociality across 3 samples of children using 6 different measures. Compared to low and high vagal tone, moderate vagal tone in early childhood concurrently predicted greater self-reported prosociality (Study 1), observed empathic concern in response to the distress of others and greater generosity toward less fortunate peers (Study 2), and longitudinally predicted greater self-, mother-, and teacher-reported prosociality 5.5 years later in middle childhood (Study 3). Taken together, our findings suggest that moderate vagal tone at rest represents a physiological preparedness or tendency to engage in different forms of prosociality across different contexts. Early moderate vagal tone may reflect an optimal balance of regulation and arousal that helps prepare children to sympathize, comfort, and share with others. PMID:27819463

    One of the main ways in transmitting parasites to humans is through consuming contaminated raw vegetables. The aim of this study was to evaluate the prevalence of parasitological contamination (helminthes eggs, Giardia and Entamoeba histolytica cysts) of salad vegetables sold at supermarkets and street vendors in Amman and Baqa’a – Jordan. A total of 133 samples of salad vegetables were collected and examined for the prevalence of parasites. It was found that 29% of the samples were contaminated with different parasites. Of the 30 lettuce, 33 tomato, 42 parsley and 28 cucumber samples examined the prevalence of Ascaris spp. eggs was 43%, 15%, 21% and 4%; Toxocara spp. eggs was 30%, 0%, 0% and 4%; Giardia spp. cysts was 23%, 6%, 0% and 0%; Taenia/Echinococcus eggs was 20%, 0%, 5% and 0%; Fasciola hepatica eggs was 13%, 3%, 2% and 0%; and E. histolytica cysts was 10%, 6%, 0% and 0%, respectively. There was no significant difference in the prevalence of parasite in salad vegetables either between supermarkets and street vendors, or between Amman and Baqa’a, Ascaris spp. was found to be the highest prevalent parasite in salad vegetables from supermarkets and street vendors and from Amman and Baqa’a. Our results pointed out that, the parasitic contamination of salad vegetables found in our study might be caused by irrigating crops with faecal contaminated water. We concluded that salad vegetables sold in Amman and Baqa’a may cause a health risk to consumers.

  4. Absenteeism movement in Greater Poland in 1840–1902

    Full Text Available The article presents the origins and development of the idea of absenteeism in Greater Poland in the 19th century. The start date for the research is 1840, which is considered to be a breakthrough year in the history of an organized absenteeism movement in Greater Poland. It was due to the Association for the Suppression of the Use of Vodka (Towarzystwo ku Przytłumieniu Używania Wódki in the Great Duchy of Posen that was then established in Kórnik. It was a secular organization that came into being on an initiative of doctor De La Roch, who was a German surgeon of a French origin. However, as early as 1844, the idea of absenteeism raised an interest of catholic clergymen of Greater Poland with high ranking clergy such as Rev. Leon Michał Przyłuski, Archbishop of Gniezno and Rev. Jan Kanty Dąbrowski, Archbishop of Posen, and later on Archbishops Rev. Mieczysław Halka Ledóchowski and Rev. Florian Oksza Stablewski. They were fascinated with activities of Rev. Jan Nepomucen Fick, Parish Priest of Piekary Śląskie and several other priests on whose initiative a lot of church brotherhoods of so called holy continence were set up in Upper Silesia as early as the first half-year of 1844. It was due to Bishop Dąbrowski that 100 000 people took vows of absenteeism in 1844–1845, becoming members of brotherhoods of absenteeism. In turn, it was an initiative of Archbishop Przyłuski that Jesuit missionaries – Rev. Karol Bołoz Antoniewicz, Rev. Teofil Baczyński and Rev. Kamil Praszałowicz, arrived in Greater Poland from Galicia in 1852 to promote the idea of absenteeism. Starting from 1848, they were helping Silesian clergymen to spread absenteeism. Clergymen of Greater Poland were also active in secular absenteeism associations. They became involved in the workings of the Association for the Promotion of Absenteeism that was set up by Zygmunt Celichowski in Kórnik in 1887, and especially in the Jutrzenka Absenteeism Association

    Revenue from corporation tax and taxes on capital income, net of revenue loss from deductibility of interest, as a percentage of the GDP has tripled in Finland over the past two decades. This is argued to result from greater openness of the economy as well as from simultaneous tax reforms towards neutrality of capital income taxation by combining tax-base broadening with tax-rate reductions. They implied improved efficiency of real investments, elimination of tax avoidance in entrepreneurial ...

    Hormone receptor (HR) negative breast cancers are relatively more common in low-risk than high-risk countries and/or populations. However, the absolute variations between these different populations are not well established given the limited number of cancer registries with incidence rate data by breast cancer subtype. We, therefore, used two unique population-based resources with molecular data to compare incidence rates for the 'intrinsic' breast cancer subtypes between a low-risk Asian population in Malaysia and high-risk non-Hispanic white population in the National Cancer Institute's surveillance, epidemiology, and end results 18 registries database (SEER 18). The intrinsic breast cancer subtypes were recapitulated with the joint expression of the HRs (estrogen receptor and progesterone receptor) and human epidermal growth factor receptor-2 (HER2). Invasive breast cancer incidence rates overall were fivefold greater in SEER 18 than in Malaysia. The majority of breast cancers were HR-positive in SEER 18 and HR-negative in Malaysia. Notwithstanding the greater relative distribution for HR-negative cancers in Malaysia, there was a greater absolute risk for all subtypes in SEER 18; incidence rates were nearly 7-fold higher for HR-positive and 2-fold higher for HR-negative cancers in SEER 18. Despite the well-established relative breast cancer differences between low-risk and high-risk countries and/or populations, there was a greater absolute risk for HR-positive and HR-negative subtypes in the US than Malaysia. Additional analytical studies are sorely needed to determine the factors responsible for the elevated risk of all subtypes of breast cancer in high-risk countries like the United States.

    For proximal gastric cancer invading the greater curvature, concomitant splenectomy is frequently performed to secure the clearance of lymph node metastases. However, prognostic impact of prophylactic splenectomy remains unclear. The aim of this study was to clarify the oncological significance of prophylactic splenectomy for advanced proximal gastric cancer invading the greater curvature. Retrospective review of 108 patients who underwent total or subtotal gastrectomy for advanced proximal gastric cancer involving the greater curvature was performed. Short-term and long-term outcomes were compared between the patients who underwent splenectomy (n = 63) and those who did not (n = 45). Patients who underwent splenectomy showed higher amount of blood loss (538 vs. 450 mL, p = 0.016) and morbidity rate (30.2 vs. 13.3, p = 0.041) compared with those who did not undergo splenectomy. In particular, pancreas-related complications were frequently observed among patients who received splenectomy (17.4 vs. 0%, p = 0.003). However, no significant improvement of long-term outcomes were confirmed in the cases with splenectomy (5-year recurrence-free rate, 60.2 vs. 67.3%; p = 0.609 and 5-year overall survival rates, 63.7 vs. 73.6%; p = 0.769). On the other hand, splenectomy was correlated with marginally better survival in patients with Borrmann type 1 or 2 gastric cancer (p = 0.072). For advanced proximal gastric cancer involving the greater curvature, prophylactic splenectomy may have no significant prognostic impact despite the increased morbidity rate after surgery. Such surgical procedure should be avoided as long as lymph node involvement is not evident.

  9. Prevalence & consequences of anaemia in pregnancy.

    Prevalence of anaemia in India is among the highest in the world. Prevalence of anaemia is higher among pregnant women and preschool children. Even among higher income educated segments of population about 50 per cent of children, adolescent girls and pregnant women are anaemic. Inadequate dietary iron, folate intake due to low vegetable consumption, perhaps low B12 intake and poor bioavailability of dietary iron from the fibre, phytate rich Indian diets are the major factors responsible for high prevalence of anaemia. Increased requirement of iron during growth and pregnancy and chronic blood loss contribute to higher prevalence in specific groups. In India, anaemia is directly or indirectly responsible for 40 per cent of maternal deaths. There is 8 to 10-fold increase in MMR when the Hb falls below 5 g/dl. Early detection and effective management of anaemia in pregnancy can contribute substantially to reduction in maternal mortality. Maternal anaemia is associated with poor intrauterine growth and increased risk of preterm births and low birth weight rates. This in turn results in higher perinatal morbidity and mortality, and higher infant mortality rate. A doubling of low birth weight rate and 2 to 3 fold increase in the perinatal mortality rates is seen when the Hb is anaemia contributes to intergenerational cycle of poor growth in the offspring. Early detection and effective management of anaemia in pregnancy can lead to substantial reduction in undernutrition in childhood, adolescence and improvement in adult height.

    Brinton, John T; Ringham, Brandy M; Glueck, Deborah H

    2015-10-13

    For studies that compare the diagnostic accuracy of two screening tests, the sample size depends on the prevalence of disease in the study population, and on the variance of the outcome. Both parameters may be unknown during the design stage, which makes finding an accurate sample size difficult. To solve this problem, we propose adapting an internal pilot design. In this adapted design, researchers will accrue some percentage of the planned sample size, then estimate both the disease prevalence and the variances of the screening tests. The updated estimates of the disease prevalence and variance are used to conduct a more accurate power and sample size calculation. We demonstrate that in large samples, the adapted internal pilot design produces no Type I inflation. For small samples (N less than 50), we introduce a novel adjustment of the critical value to control the Type I error rate. We apply the method to two proposed prospective cancer screening studies: 1) a small oral cancer screening study in individuals with Fanconi anemia and 2) a large oral cancer screening trial. Conducting an internal pilot study without adjusting the critical value can cause Type I error rate inflation in small samples, but not in large samples. An internal pilot approach usually achieves goal power and, for most studies with sample size greater than 50, requires no Type I error correction. Further, we have provided a flexible and accurate approach to bound Type I error below a goal level for studies with small sample size.

    Although having a large diversity of types of procedures has a substantial operational impact on the surgical suites of hospitals, the strategic importance is unknown. In the current study, we used longitudinal data for all hospitals and patient ages in the State of Florida to evaluate whether hospitals with greater diversity of types of physiologically complex major therapeutic procedures (PCMTP) also had greater rates of surgical growth. Observational cohort study. 1479 combinations of hospitals in the State of Florida and fiscal years, 2008-2015. The types of International Classification of Diseases, Ninth revision, Clinical Modification (ICD-9-CM) procedures studied were PCMT, defined as: a) major therapeutic procedure; b) >7 American Society of Anesthesiologists base units; and c) performed during a hospitalization with a Diagnosis Related Group with a mean length of stay ≥4.0days. The number of procedures of each type of PCMTP commonly performed at each hospital was calculated by taking 1/Herfindahl index (i.e., sum of the squares of the proportions of all procedures of each type of PCMTP). Over the 8 successive years studied, there was no change in the number of PCMTP being performed (Kendall's τ b =-0.014±0.017 [standard error], P=0.44; N=1479 hospital×years). Busier and larger hospitals commonly performed more types of PCMTP, respectively categorized based on performed PCMTP (τ=0.606±0.017, P<0.0001) or hospital beds (τ=0.524±0.017, P<0.0001). There was no association between greater diversity of types of PCMTP commonly performed and greater annual growth in numbers of PCMTP (τ=0.002±0.019, P=0.91; N=1295 hospital×years). Conclusions were the same with multiple sensitivity analyses. Post hoc, it was recognized that hospitals performing a greater diversity of PCMTP were more similar to the aggregate of other hospitals within the same health district (τ=0.550±0.017, P<0.0001). During a period with no overall growth in PCMTP, hospitals with

    Problem gambling in adolescents has recently emerged as a pressing public health concern. In this context and in light of the pervasive financial crisis in Greece, the present study aimed to explore adolescents' gambling involvement in Athens region to estimate the prevalence of its problematic form and to identify its risk/protective factors. A total of 2141 students were recruited from a representative sample of 51 schools located in greater Athens area. The presence of problem gambling was assessed through the use of the DSM-IV-MR-J questionnaire. Data were collected in the form of a self-reported questionnaire during one school hour. Results indicate that 1-year prevalence of high severity problem gambling was found to be 5.6%. Regarding the risk factors for problem gambling; male gender, parental engagement with gambling activities, living without the parents, low grades at school, foreign nationality and the referent absence of availability of food in the household, increased the risk of suffering from the disorder. Gambling behavior among adolescents constitutes a problem in Greece and highlights the need for designing and implementing appropriate preventive interventions, especially amid the ongoing financial crisis.

  14. The post-orgasmic prolactin increase following intercourse is greater than following masturbation and suggests greater satiety.

    2006-03-01

    Research indicates that prolactin increases following orgasm are involved in a feedback loop that serves to decrease arousal through inhibitory central dopaminergic and probably peripheral processes. The magnitude of post-orgasmic prolactin increase is thus a neurohormonal index of sexual satiety. Using data from three studies of men and women engaging in masturbation or penile-vaginal intercourse to orgasm in the laboratory, we report that for both sexes (adjusted for prolactin changes in a non-sexual control condition), the magnitude of prolactin increase following intercourse is 400% greater than that following masturbation. The results are interpreted as an indication of intercourse being more physiologically satisfying than masturbation, and discussed in light of prior research reporting greater physiological and psychological benefits associated with coitus than with any other sexual activities.

    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.

    2010-06-01

    In the United States, as elsewhere, a growing debate pits national energy policy and homeland security against biological conservation. In rural communities the extraction of fossil fuels is often encouraged because of the employment opportunities it offers, although the concomitant itinerant workforce is often associated with increased wildlife poaching. We explored possible positive and negative factors associated with energy extraction in the Greater Yellowstone Ecosystem (GYE), an area known for its national parks, intact biological diversity, and some of the New World's longest terrestrial migrations. Specifically, we asked whether counties with different economies-recreation (ski), agrarian (ranching or farming), and energy extractive (petroleum)-differed in healthcare (gauged by the abundance of hospital beds) and in the frequency of sexual predators. The absolute and relative frequency of registered sex offenders grew approximately two to three times faster in areas reliant on energy extraction. Healthcare among counties did not differ. The strong conflation of community dishevel, as reflected by in-migrant sexual predators, and ecological decay in Greater Yellowstone is consistent with patterns seen in similar systems from Ecuador to northern Canada, where social and environmental disarray exist around energy boomtowns. In our case, that groups (albeit with different aims) mobilized campaigns to help maintain the quality of rural livelihoods by protecting open space is a positive sign that conservation can matter, especially in the face of rampant and poorly executed energy extraction projects. Our findings further suggest that the public and industry need stronger regulatory action to instill greater vigilance when and where social factors and land conversion impact biological systems.

    2005-01-01

    A new land cover database of Greater Mesoamerica has been prepared using moderate resolution imaging spectroradiometer (MODIS, 500 m resolution) satellite data. Daily surface reflectance MODIS data and a suite of ancillary data were used in preparing the database by employing a decision tree classification approach. The new land cover data are an improvement over traditional advanced very high resolution radiometer (AVHRR) based land cover data in terms of both spatial and thematic details. The dominant land cover type in Greater Mesoamerica is forest (39%), followed by shrubland (30%) and cropland (22%). Country analysis shows forest as the dominant land cover type in Belize (62%), Cost Rica (52%), Guatemala (53%), Honduras (56%), Nicaragua (53%), and Panama (48%), cropland as the dominant land cover type in El Salvador (60.5%), and shrubland as the dominant land cover type in Mexico (37%). A three-step approach was used to assess the quality of the classified land cover data: (i) qualitative assessment provided good insight in identifying and correcting gross errors; (ii) correlation analysis of MODIS- and Landsat-derived land cover data revealed strong positive association for forest (r2 = 0.88), shrubland (r2 = 0.75), and cropland (r2 = 0.97) but weak positive association for grassland (r2 = 0.26); and (iii) an error matrix generated using unseen training data provided an overall accuracy of 77.3% with a Kappa coefficient of 0.73608. Overall, MODIS 500 m data and the methodology used were found to be quite useful for broad-scale land cover mapping of Greater Mesoamerica.

    A wealth of research has shown that retrieval practice plays a significant role in improving memory retention. The current study focused on one simple yet rarely examined question: would repeated retrieval using two different retrieval routes or using the same retrieval route twice lead to greater long-term memory retention? Participants elaborately learned 22 Japanese-Chinese translation word pairs using two different mediators. Half an hour after the initial study phase, the participants completed two retrieval sessions using either one mediator (Tm1Tm1) or two different mediators (Tm1Tm2). On the final test, which was performed 1week after the retrieval practice phase, the participants received only the cue with a request to report the mediator (M1 or M2) followed by the target (Experiment 1) or only the mediator (M1 or M2) with a request to report the target (Experiment 2). The results of Experiment 1 indicated that the participants who practiced under the Tm1Tm2 condition exhibited greater target retention than those who practiced under the Tm1Tm1 condition. This difference in performance was due to the significant disadvantage in mediator retrieval and decoding of the unpracticed mediator under the Tm1Tm1 condition. Although mediators were provided to participants on the final test in Experiment 2, decoding of the unpracticed mediators remained less effective than decoding of the practiced mediators. We conclude that practicing multiple retrieval routes leads to greater memory retention than focusing on a single retrieval route. Thus, increasing retrieval variability during repeated retrieval practice indeed significantly improves long-term retention in a delay test. Copyright © 2016 Elsevier B.V. All rights reserved.

    Notwithstanding the general interest and the geopolitical importance of the island countries in the Greater Antilles, little is known about the specific ancestral Native American and African populations that settled them. In an effort to alleviate this lacuna of information on the genetic constituents of the Greater Antilles, we comprehensively compared the mtDNA compositions of Cuba, Dominican Republic, Haiti, Jamaica and Puerto Rico. To accomplish this, the mtDNA HVRI and HVRII regions, as well as coding diagnostic sites, were assessed in the Haitian general population and compared to data from reference populations. The Taino maternal DNA is prominent in the ex-Spanish colonies (61.3%-22.0%) while it is basically non-existent in the ex-French and ex-English colonies of Haiti (0.0%) and Jamaica (0.5%), respectively. The most abundant Native American mtDNA haplogroups in the Greater Antilles are A2, B2 and C1. The African mtDNA component is almost fixed in Haiti (98.2%) and Jamaica (98.5%), and the frequencies of specific African haplogroups vary considerably among the five island nations. The strong persistence of Taino mtDNA in the ex-Spanish colonies (and especially in Puerto Rico), and its absence in the French and English excolonies is likely the result of different social norms regarding mixed marriages with Taino women during the early years after the first contact with Europeans. In addition, this article reports on the results of an integrative approach based on mtDNA analysis and demographic data that tests the hypothesis of a southward shift in raiding zones along the African west coast during the period encompassing the Transatlantic Slave Trade.

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

    Although health care professionals may be assumed to make healthier lifestyle choices and have better health outcomes than others because of their greater health literacy, little is known about how actual health outcomes of health care professionals compare with those of the overall population. We analyzed how trends in obesity, diabetes, hypertension, and coronary artery disease prevalence as well as several health behaviors (smoking, alcohol use, and exercise) varied between health care professionals and the general US population from 2002 to 2013, using nationally representative data collected by the National Health Interview Survey. We estimated multivariate logistic regressions of each disease and behavior adjusted for age, race, sex, geographic region, and year. Although rates of obesity, diabetes, and hypertension were lower among health care professionals compared with the overall population, disease was still common among health care professionals and increased over time at a rate similar to that of the overall population. For example, obesity prevalence was lower among health care professionals but increased similarly from 2002 to 2013 (health care professionals, 20.5% in 2002 to 22.1% in 2013; other occupations, 28.4% to 31.7%; P=.64 for difference in trend). Diabetes prevalence was modestly lower among health care professionals but increased at a similar rate (health care professionals, 7.4% in 2005 to 8.6% in 2013; other occupations, 8.7% to 9.9%; P=.67 for difference in trend). Similar patterns were noted in hypertension. Coronary artery disease prevalence declined over time among health care professionals but increased for others. Health care professionals reported better health behaviors than others in smoking and physical activity but not in moderate to heavy alcohol use.

    Full Text Available Figure skating is a physically demanding sport that requires a unique combination of artistic ability, speed, agility, flexibility and power. During the last decades not only the competitive schedule has become tougher, but after introduction of the new judging system in 2003, also more emphasis is put on difficult technical elements, jumps, steps and spins (ISU Rules, 2006. More studies about possible increasing prevalence of stress fractures in figure skaters and contributing factors are lacking (Dubravcic-Simunjak et al., 2003; Moran, 2000; Pecina et al., 1990. Therefore the aim of this study was to obtain data about the current stress fracture cumulative risk among elite junior and senior figure skaters, as well as possible factors that may contribute to stress fracture incidence. An anonymous questionnaire, divided into 5 sections, inquired about the prevalence of stress fracture were mailed and distributed to all 62 International Skating Union (ISU members by the ISU headquarters in Lausanne, Switzerland. The guidelines of the Helsinki declaration 2004 were followed. From the 644 skaters who received the questionnaire, 412 completed ones were returned from 110 female juniors (78 single skaters, 12 pair skaters and 20 ice dancers and 135 female seniors (97 single skaters, 16 pair skaters and 22 ice dancers and from 79 male juniors (47 single skaters, 12 pair skaters and 20 ice dancers and 88 male seniors (50 single skaters, 16 pair skaters and 22 ice dancers, coming from different ISU members. The response rate was 62% in females and 67% in males. The median age for female skaters was 16 years and for males 18 years (range 12-25 years. All participants started to skate between 3 and 6 years of age and started to compete in national and international competitions when they were between 5 and 7 years old. At the time of this analysis, they had been skating between 9 and 20 years.In females 41 (16.7%, and in males 25 (13.8% figure skaters

    Many studies have demonstrated that women are substantially underrepresented in cardiovascular trials, but few have considered that women develop cardiovascular disease at older ages than men. The extent to which observed gender enrollment inequalities persist after accounting for age-gender differences in disease prevalence is unknown. The purpose of the study was to compare observed rates of women participating in cardiovascular clinical trials with expected rates of female participation based on age- and gender-specific population disease prevalence. Publications between 1997 and 2009 in the three leading medical journals were included to calculate observed women's enrollment rates. Population-based data in Canada were used to determine the expected enrollment rates of women. Multicenter, randomized cardiovascular clinical trials that enrolled both men and women were analyzed. Two reviewers independently extracted data on women's enrollment and important clinical trial characteristics. The female enrollment rate was 30% in the included 325 trials, which ranged from 27% in trials of coronary artery disease, 27% in heart failure, 31% in arrhythmia, to 45% in primary prevention. Increased female enrollment correlated strongly with increasing age at recruitment in cardiovascular clinical trials (P disease prevalence, gaps in female enrollment were much lower than the expected enrollment rates estimated by 5% in coronary artery disease, 13% in heart failure, 9% in arrhythmia, and 3% in primary prevention. Only cardiovascular trials were evaluated in our study. Female underrepresentation in cardiovascular clinical trials is smaller than conventionally believed after accounting for age- and gender-specific population disease prevalence. Our findings suggest that greater representation of women in cardiovascular clinical trials can be achieved through the recruitment of older populations.

    Dysphagia is relatively common in patients with Parkinson disease (PD) and can have a negative impact on their quality of life; therefore, it is imperative that its prevalence in PD patients is studied. The aim of this study was to explore the prevalence and clinical correlation of dysphagia in Chinese PD patients. We recruited 116 Chinese PD patients. A videofluoroscopic study of swallowing (VFSS) was used to identify dysphagia. Assessments, including water drinking test, relative motor symptoms, non-motor symptoms (NMS) and quality of life, were performed to analyze the risks of dysphagia. The prevalence of dysphagia was 87.1%. The comparison of demographic and clinical features between patients with and without dysphagia included sex, education level, disease course, Mini-mental State Examination (MMSE), Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), Question 6, 7 of the Unified Parkinson Disease Rating Scale (UPDRS Part II), Hoehn-Yahr stage (H&Y), water drinking test, 39-item Parkinson Disease Questionnaire (PDQ-39) and Non-Motor Symptoms Quest (NMSQ). We found significant correlations between dysphagia and age. Using age, disease course, and H&Y stage as the independent variable in our regression analysis for assessing the risk factors of dysphagia in PD patients, age and H&Y stage displayed a strong correlation as the risk factors. The risk of dysphagia in elderly PD patients is 1.078 times greater than that of younger PD patients. Also, the risk of dysphagia in PD patients of a greater H&Y staging is 3.260 times greater than that of lower staging PD patients. Our results suggest that dysphagia is common in Chinese PD patients. Older patients or those in higher H&Y stages are more likely to experience dysphagia. There is no correlation between dysphagia and PD duration.

  6. Absorption spectrum of DNA for wavelengths greater than 300 nm

    Although DNA absorption at wavelengths greater than 300 nm is much weaker than that at shorter wavelengths, this absorption seems to be responsible for much of the biological damage caused by solar radiation of wavelengths less than 320 nm. Accurate measurement of the absorption spectrum of DNA above 300 nm is complicated by turbidity characteristic of concentrated solutions of DNA. We have measured the absorption spectra of DNA from calf thymus, Clostridium perfringens, Escherichia coli, Micrococcus luteus, salmon testis, and human placenta using procedures which separate optical density due to true absorption from that due to turbidity. Above 300 nm, the relative absorption of DNA increases as a function of guanine-cytosine content, presumably because the absorption of guanine is much greater than the absorption of adenine at these wavelengths. This result suggests that the photophysical processes which follow absorption of a long-wavelength photon may, on the average, differ from those induced by shorter-wavelength photons. It may also explain the lower quantum yield for the killing of cells by wavelengths above 300 nm compared to that by shorter wavelengths

    Over one-third of breast cancer survivors experience upper extremity disability. Black women present with factors associated with greater upper extremity disability, including: increased body mass index (BMI), more advanced disease stage at diagnosis, and varying treatment type compared with Whites. No prior research has evaluated the relationship between race and upper extremity disability using validated tools and controlling for these factors. Data were drawn from a survey study among 610 women with stage I-III hormone receptor positive breast cancer. The disabilities of the arm, shoulder and hand (QuickDASH) is an 11-item self-administered questionnaire that has been validated for breast cancer survivors to assess global upper extremity function over the past 7 days. Linear regression and mediation analysis estimated the relationships between race, BMI and QuickDASH score, adjusting for demographics and treatment types. Black women (n = 98) had 7.3 points higher average QuickDASH scores than White (n = 512) women (p disability by 40 %. Even several years post-treatment, Black breast cancer survivors had greater upper extremity disability, which was partially mediated by higher BMIs. Close monitoring of high BMI Black women may be an important step in reducing disparities in cancer survivorship. More research is needed on the relationship between race, BMI, and upper extremity disability.

    Low-level radioactive wastes include a broad spectrum of wastes that have different radionuclide concentrations, half-lives, and physical and chemical properties. Standard shallow-land burial practice can provide adequate protection of public health and safety for most low-level wastes, but a small volume fraction (about 1%) containing most of the activity inventory (approx.90%) requires specific measures known as ''greater-confinement disposal'' (GCD). Different site characteristics and different waste characteristics - such as high radionuclide concentrations, long radionuclide half-lives, high radionuclide mobility, and physical or chemical characteristics that present exceptional hazards - lead to different GCD facility design requirements. Facility design alternatives considered for GCD include the augered shaft, deep trench, engineered structure, hydrofracture, improved waste form, and high-integrity container. Selection of an appropriate design must also consider the interplay between basic risk limits for protection of public health and safety, performance characteristics and objectives, costs, waste-acceptance criteria, waste characteristics, and site characteristics. This paper presents an overview of the factors that must be considered in planning the application of methods proposed for providing greater confinement of low-level wastes. 27 refs

    Full Text Available Recycling nutrients form sanitary wastes back into agricultural ecosystems offers an option to alleviate soil depletion in regions where the use of mineral fertiliser is limited. Exemplary nutrient and water cycling approaches, including collection, treatment and use of human urine, are established at Valley View University (VVU in Greater Accra, Ghana.Concerns have been recently raised in regard to fate and impact of pharmaceutical residues in soils and interlinked environment. To evaluate in how far emerging knowledge can be transposed onto VVU, urban and rural environments in Greater Accra, spatial disease occurrence and drug consumption patterns were studied. Malaria has been found to represent the most severe health burden in Ghana, but there is also a high prevalence of infectious diseases. Drugs consumed in great quantities and in respect to their residual loads potentially problematic in the environment belong to therapeutic groups of: antibiotics, analgesics, drugs for diabetes, antimalarials, cardiovascular drugs and anthelmintics. Drug consumption revealed to be highest in urban and lowest in rural areas. At VVU the range of consumed drugs is comparable to urban areas except for the negligible use of diabetes and cardiovascular medication as well as contraceptives.

Data from other studies were compared to those resulting from this study. RESULTS: There were significant differences in parental income, socioeconomic condition and education between the two groups of infants; however, no significant difference was observed in the breastfeeding rates between the two groups. Overall, in both groups, the prevalence of exclusive breastfeeding in 4-month-old infants was 61.1%, and the average period of exclusive breastfeeding was 120 days. These results were higher than those registered in other studies. CONCLUSIONS: The results showed differences between the socio-economic levels of the two groups, but no differences in the breastfeeding indicators between them.. The overall rates of exclusive breastfeeding in the city of Lins, SP, Brazil, were higher than the rates reported in other investigations.

    Hepatitis C virus (HCV) antiviral treatment for people who inject drugs (PWID) could prevent onwards transmission and reduce chronic prevalence. We assessed current PWID treatment rates in seven UK settings and projected the potential impact of current and scaled-up treatment on HCV chronic prevalence. Data on number of PWID treated and sustained viral response rates (SVR) were collected from seven UK settings: Bristol (37-48% HCV chronic prevalence among PWID), East London (37-48%), Manchester (48-56%), Nottingham (37-44%), Plymouth (30-37%), Dundee (20-27%) and North Wales (27-33%). A model of HCV transmission among PWID projected the 10-year impact of (i) current treatment rates and SVR (ii) scale-up with interferon-free direct acting antivirals (IFN-free DAAs) with 90% SVR. Treatment rates varied from <5 to over 25 per 1000 PWID. Pooled intention-to-treat SVR for PWID were 45% genotypes 1/4 [95%CI 33-57%] and 61% genotypes 2/3 [95%CI 47-76%]. Projections of chronic HCV prevalence among PWID after 10 years of current levels of treatment overlapped substantially with current HCV prevalence estimates. Scaling-up treatment to 26/1000 PWID annually (achieved already in two sites) with IFN-free DAAs could achieve an observable absolute reduction in HCV chronic prevalence of at least 15% among PWID in all sites and greater than a halving in chronic HCV in Plymouth, Dundee and North Wales within a decade. Current treatment rates among PWID are unlikely to achieve observable reductions in HCV chronic prevalence over the next 10 years. Achievable scale-up, however, could lead to substantial reductions in HCV chronic prevalence. © 2014 The Authors Journal of Viral Hepatitis Published by John Wiley & Sons Ltd.

    2017-01-01

    PURPOSE OF THE STUDY This retrospective study aims to present short-term clinical outcomes of endoscopic treatment of patients with greater trochanteric pain syndrome (GTPS). MATERIAL AND METHODS The evaluated study population was composed of a total of 19 patients (16 women, 3 men) with the mean age of 47 years (19-63 years). In twelve cases the right hip joint was affected, in the remaining seven cases it was the left side. The retrospective evaluation was carried out only in patients with greater trochanteric pain syndrome caused by independent chronic trochanteric bursitis without the presence of m. gluteus medius tear not responding to at least 3 months of conservative treatment. In patients from the followed-up study population, endoscopic trochanteric bursectomy was performed alone or in combination with iliotibial band release. The clinical results were evaluated preoperatively and with a minimum follow-up period of 1 year after the surgery (mean 16 months). The Visual Analogue Scale (VAS) for assessment of pain and WOMAC (Western Ontario MacMaster) score were used. In both the evaluated criteria (VAS and WOMAC score) preoperative and postoperative results were compared. Moreover, duration of surgery and presence of postoperative complications were assessed. Statistical evaluation of clinical results was carried out by an independent statistician. In order to compare the parameter of WOMAC score and VAS pre- and post-operatively the Mann-Whitney Exact Test was used. The statistical significance was set at 0.05. RESULTS The preoperative VAS score ranged 5-9 (mean 7.6) and the postoperative VAS ranged 0-5 (mean 2.3). The WOMAC score ranged 56.3-69.7 (mean 64.2) preoperatively and 79.8-98.3 (mean 89.7) postoperatively. When both the evaluated parameters of VAS and WOMAC score were compared in time, a statistically significant improvement (ppain syndrome yields statistically significant improvement of clinical results with the concurrent minimum incidence of

    Earlier studies in nursing homes show a high prevalence of cognitive impairment, dependency in activities of daily living (ADL), pain, and neuropsychiatric symptoms among residents. The aim of this study was to explore the prevalence of the above among residents in a nationally representative sample of Swedish nursing homes, and to investigate whether pain and neuropsychiatric symptoms differ in relation to gender, cognitive function, ADL-capacity, type of nursing-home unit and length of stay. Cross-sectional data from 188 randomly selected nursing homes were collected. A total of 4831 residents were assessed for cognitive and ADL function, pain and neuropsychiatric symptoms. Data were analysed using descriptive statistics and the chi-square test. The results show the following: the prevalence of cognitive impairment was 67 %, 56 % of residents were ADL-dependent, 48 % exhibited pain and 92 % exhibited neuropsychiatric symptoms. The prevalence of pain did not differ significantly between male and female residents, but pain was more prevalent among cognitively impaired and ADL-dependent residents. Pain prevalence was not significantly different between residents in special care units for people with dementia (SCU) and general units, or between shorter-and longer-stay residents. Furthermore, the prevalence of neuropsychiatric symptoms did not differ significantly between male and female residents, between ADL capacities or in relation to length of stay. However, residents with cognitive impairment and residents in SCUs had a significantly higher prevalence of neuropsychiatric symptoms than residents without cognitive impairment and residents in general units. The prevalence rates ascertained in this study could contribute to a greater understanding of the needs of nursing-home residents, and may provide nursing home staff and managers with trustworthy assessment scales and benchmark values for further quality assessment purposes, clinical development work and

    The strontium isotope geochemistry is given for three Puerto Rican intrusive rocks: the granodioritic Morovis and San Lorenzo plutons and the Rio Blanco stock of quartz dioritic composition. The average calculated initial 87 Sr/ 86 Sr ratios are 0.70370, 0.70355 and 0.70408, respectively. In addition, the San Lorenzo data establish a whole-rock isochron of 71 +- 2 m.y., which agrees with the previously reported K-Ar age of 73 m.y. Similarity of most of the intrusive rocks in the Greater Antilles with respect to their strontium isotopic geochemistry regardless of their major element composition indicates that intrusive magmas with a wide range of composition can be derived from a single source material. The most likely source material, in view of the available isotopic data, is the mantle wedge overlying the subduction zone. (orig.)

  11. ADR characteristics and corporate governance in the Greater China region

    2012-04-01

    Full Text Available We examine the relationship between firm valuation and governance mechanisms, firm characteristics, and institutional factors of the American Depository Receipts (ADRs domiciled in the Greater China region. We find that China ADRs have the highest market-to-book value ratio followed by Hong Kong and Taiwan ADRs. It appears that Chinese firms with the poorest external governance environment stand to benefit the most from cross listing under the ADR programs. Listing in the U.S. that requires more stringent regulations and disclosure rules may strengthen the firms’ governance practices and thereby enhance their firm value. Among the internal governance mechanisms, institutional ownership and insider ownership are important for firm value.

GCD practices of waste segregation, packaging, emplacement below the root zone, and waste stabilization are being used in the demonstration. Activity concentrations to select wastes for GCD are based on a study of SRP burial records, and are equal to or less than those for Class B waste in 10CFR61. The first disposal units to be constructed are 9-foot diameter, thirty-foot deep boreholes which will be used to dispose of wastes from production reactors, tritiated wastes, and selected wastes from off-site. In 1984 an engineered GCD trench will be constructed for disposal of boxed wastes and large bulky items. 2 figures, 1 table

    Plans for improved LLW disposal at the Savannah River Plant include Greater Confinement Disposal (GCD) for the higher activity fractions of this waste. GCD practices will include waste segregation, packaging, emplacement below the root zone, and stabilizing the emplacement with cement. Statistical review of SRP burial records showed that about 95% of the radioactivity is associated with only 5% of the waste volume. Trigger values determined in this study were compared with actual burials in 1982 to determine what GCD facilities would be needed for a demonstration to begin in Fall 1983. Facilities selected include 8-feet-diameter x 30-feet-deep boreholes to contain reactor scrap, tritiated waste, and selected wastes from offsite

    We propose that dishonest and creative behavior have something in common: They both involve breaking rules. Because of this shared feature, creativity may lead to dishonesty (as shown in prior work), and dishonesty may lead to creativity (the hypothesis we tested in this research). In five experiments, participants had the opportunity to behave dishonestly by overreporting their performance on various tasks. They then completed one or more tasks designed to measure creativity. Those who cheated were subsequently more creative than noncheaters, even when we accounted for individual differences in their creative ability (Experiment 1). Using random assignment, we confirmed that acting dishonestly leads to greater creativity in subsequent tasks (Experiments 2 and 3). The link between dishonesty and creativity is explained by a heightened feeling of being unconstrained by rules, as indicated by both mediation (Experiment 4) and moderation (Experiment 5).

    a positive impact on expatriates' job performance. Therefore, the purpose of this paper is toexamine the association between the age of business expatriates and their work performance in a Chinese cultural setting. Design/methodology/approach - Controlling for the potential bias of a number of background......, companies should not discriminate against older candidatesin expatriate selection for Greater China. Furthermore, older expatriates destined for a Chinesecultural context could be trained how to exploit their age advantage. Originality/value - In contrast to previous studies, this investigation attempts...... to match a certain personal characteristic of expatriates with a specific host culture. The results have implications for and contribute to the literature on expatriate selection as well as to the body of research on crosscultural training....

    Alexithymia is characterized by a difficulty identifying and describing emotional states, as well as an externally oriented thinking style. This study investigated the prevalence of alexithymia in a British undergraduate sample and assesses its relationship to both parental bonding and dissociation. The Toronto alexithymia scale (TAS-20), the Parental Bonding Instrument (PBI), and the Dissociative Experience Scale (DES) were administered to a sample of 181 male and 190 female undergraduate students from both arts and science subjects. Rates of alexithymia were comparable with those observed in some other countries. Contrary to predictions, females were found to have higher rates than males, and the highest presence of alexithymia was in female science students. As in previous studies, alexithymia was linked to both dissociation and perceptions of a lack of maternal care, though the degree of association to the latter was small. Dissociative experiences were predicted by both maternal overprotection and difficulties identifying feelings. Some qualified support was found for the relevance of early maternal bonding to later difficulties processing emotions. The presence of greater alexithymia in females, and female science students in particular, was discussed in reference to similar observations elsewhere. There was also an understandable relationship between 'difficulty identifying feelings' (TAS) and both depersonalization/derealization and absorption (DES).

  18. Economic and geographic factors affecting the development of Greater Baku

    Full Text Available Globally, the responsible factors for the ongoing development of urbanization are the high speed of population growth, and the mass migration of humans to cities and large urban areas. In most countries, this process resulted in the emergence of ‘pseudo-urbanization’ which is difficult to be regulated. The purpose of the carried researches to determine the development priorities in the territory of Greater Baku – the capital city of the Republic of Azerbaijan; to define the problems that take place in this connection; and to develop ways of elimination of these problems. The reason of taking Baku as a research area is connected with some of the factors. Firstly, studies on Baku have been conducted based on the Soviet geographical and urban planning school and their methods for a long period. In this regard, it is necessary to carry out research in this field based on the principles adopted in most countries. Secondly, since 1992, the intensive accumulation of population in the territory of the capital city and the surrounding areas is being observed because of socio-economic problems. As a result, the process of pseudo-urbanization intensified, entailing a densely-populated area. Thirdly, low-rise buildings still continue to exist in the large areas within the territory of Baku, and they are not associated with the functional structure of the city. This situation creates many challenges, particularly in terms of density growth and effective use of the city’s territory. Finally, numerous new buildings have been constructed in the residential areas of Baku in recent years, and this may entailserious problems in water supply, energy provision, and utilities. The study is carried out referring to previous works of researchers, statistic data, and the results of the population census conducted in 1959-2009.The practical significance of the scientific work is that positive and negative factors affecting the further development of Greater Baku

    Two studies examined the notion that negative affectivity (Watson & Clark, 1984) is associated with more accurate perceptions of conveyed impressions in social interactions. In Study 1 (n = 160), low self-esteem (LSE) and high self-esteem (HSE) subjects were paired with either an LSE or an HSE partner. After a 15-min interaction, they rated themselves, their partners, and how they believed their partners would rate them on 20 adjectives related to social competence. Study 2 (n = 40) was identical except that each interaction was observed by 2 observers who rated each participant, and participants also rated how they believed an observer would rate them. LSE subjects exhibited greater accuracy only with respect to the elevation component of observers' ratings; HSE subjects overestimated the positivity of observers' evaluations, whereas LSE subjects were relatively accurate. However, LSE subjects exhibited less overall accuracy with respect to their partners' ratings. We argue that when these results are considered with earlier research, there is no support for the notion of depressive realism in assessing conveyed impressions.

  20. Effects of the May 5-6, 1973, storm in the Greater Denver area, Colorado

    Rain began falling on the Greater Denver area the evening of Saturday, May 5, 1973, and continued through most of Sunday, May 6. Below about 7,000 feet altitude, the precipitation was mostly rain; above that altitude, it was mostly snow. Although the rate of fall was moderate, at least 4 inches of rain or as much as 4 feet of snow accumulated in some places. Sustained precipitation falling at a moderate rate thoroughly saturated the ground and by midday Sunday sent most of the smaller streams into flood stage. The South Platte River and its major tributaries began to flood by late Sunday evening and early Monday morning. Geologic and hydrologic processes activated by the May 5-6 storm caused extensive damage to lands and to manmade structures in the Greater Denver area. Damage was generally most intense in areas where man had modified the landscape--by channel constrictions, paving, stripping of vegetation and topsoil, and oversteepening of hillslopes. Roads, bridges, culverts, dams, canals, and the like were damaged or destroyed by erosion and sedimentation. Streambanks and structures along them were scoured. Thousands of acres of croplands, pasture, and developed urban lands were coated with mud and sand. Flooding was intensified by inadequate storm sewers, blocked drains, and obstructed drainage courses. Saturation of hillslopes along the Front Range caused rockfalls, landslides, and mudflows as far west as Berthoud Pass. Greater attention to geologic conditions in land-use planning, design, and construction would minimize storm damage in the future.
