Understanding HIV incidence, the rate at which new infections occur in populations, is critical for tracking and surveillance of the epidemic. In this article, we derive methods for determining sample sizes for cross-sectional surveys to estimate incidence with sufficient precision. We further show how to specify sample sizes for two successive cross-sectional surveys to detect changes in incidence with adequate power. In these surveys biomarkers such as CD4 cell count, viral load, and recently developed serological assays are used to determine which individuals are in an early disease stage of infection. The total number of individuals in this stage, divided by the number of people who are uninfected, is used to approximate the incidence rate. Our methods account for uncertainty in the durations of time spent in the biomarker defined early disease stage. We find that failure to account for this uncertainty when designing surveys can lead to imprecise estimates of incidence and underpowered studies. We evaluated our sample size methods in simulations and found that they performed well in a variety of underlying epidemics. Code for implementing our methods in R is available with this article at the Biometrics website on Wiley Online Library. © 2015, The International Biometric Society.

Lobectomy for non-small cell lung cancer (NSCLC) can be performed either through open thoracotomy or video-assisted thoracoscopic surgery (VATS). To improve the understanding of current attitudes of the thoracic community toward VATS lobectomy, the Collaborative Research Group conducted the Cross-sectional Survey on Lobectomy Approach (X-SOLA) study. We surveyed a large cohort of lobectomy-performing thoracic surgeons to examine their adoption of VATS lobectomy and their opinions of this technique vs conventional open thoracotomy. Participants included thoracic surgeons identified through an international index search from the Web of Science and the cardiothoracic surgery network. A confidential questionnaire was e-mailed in June 2012. Nonresponders were given two reminder e-mails at monthly intervals. The questionnaire, completed by 838 thoracic surgeons within a 3-month period, identified 416 surgeons who only performed lobectomy through open thoracotomy and 422 surgeons who performed VATS or robotic VATS. Of those who performed VATS, 95% agreed with the definition of "true" VATS lobectomy according to the Cancer and Leukemia Group B trial. Ninety-two percent of surgeons who did not perform VATS lobectomy responded that they were willing to learn this technique, but were hindered by limited resources, exposure, and mentoring. Both groups agreed there was a need for VATS lobectomy training in thoracic residency programs and in standardized workshops. X-SOLA represents the largest cross-sectional report within the thoracic community to date, demonstrating the penetration of VATS lobectomy for NSCLC internationally. From our study, we were able to identify a number of obstacles to broaden the adoption of this minimally invasive technique.

Food consumption surveys are performed in many countries. Comparison of results from those surveys across nations is difficult because of differences in methodological approaches. While consensus about the preferred methodology associated with national food consumption surveys is increasing, no inventory of methodological aspects across continents is available. The aims of the present review are (1) to develop a framework of key methodological elements related to national food consumption surveys, (2) to create an inventory of these properties of surveys performed in the continents North-America, South-America, Asia and Australasia, and (3) to discuss and compare these methodological properties cross-continentally. A literature search was performed using a fixed set of search terms in different databases. The inventory was completed with all accessible information from all retrieved publications and corresponding authors were requested to provide additional information where missing. Surveys from ten individual countries, originating from four continents are listed in the inventory. The results are presented according to six major aspects of food consumption surveys. The most common dietary intake assessment method used in food consumption surveys worldwide is the 24-HDR (24 h dietary recall), occasionally administered repeatedly, mostly using interview software. Only three countries have incorporated their national food consumption surveys into continuous national health and nutrition examination surveys. PMID:25984745

Blood products use has increased in France between 2000 and 2011. To understand the reasons for this increase, data about transfused patients and transfusion practices needed to be updated. A nationwide cross-sectional survey was performed with health care establishments. Diagnoses and indication for the transfusion, pretransfusion laboratory results, and blood products used were collected during a randomly selected 24-hour period in 2011. All patients who received at least one blood product delivered on the survey day were included. A total of 10,794 blood products were requested for 4720 patients: 8688 red blood cell (RBC) units, 842 platelet (PLT) concentrates, and 1264 fresh-frozen plasma (FFP) units. Hematologic and cancer pathologies included 46% of transfused patients, 34% of the patients had transfusions in a surgical context, and 32.4% of transfused patients were receiving medication with an impact on transfusion. Nearly half of RBC transfusions were performed with hemoglobin levels of less than 8 g/dL. PLT transfusions for prophylactic indication were prescribed with PLT counts of less than 20 × 10 9 and 50 × 10 9 /L in 56.9 and 86.6% of patients, respectively. RBCs and PLTs transfusion practices were in agreement with national guidelines. FFP units were involved in 8.0% of all prescriptions. Among these, 57.4% were requested in the context of an acute hemorrhage and 8.4% for plasma exchange. The median of FFP use (n = 2) in a nonsurgical context, excluding plasma exchange, suggests an insufficient dosing of FFP. Except for insufficient FFP dosing per patient and limitations on assessment of indications for prescribing, transfusion practices were in agreement with national guidelines. © 2016 AABB.

Background Transactional sex is associated with the HIV epidemic among young people in Uganda. Few quantitative studies based on nationally representative survey data explored the relationship between sexual behaviors, HIV infection, and transactional sex. Objective This study aimed to determine the associations between risky sexual behaviors, participation in transactional sex, and HIV sero-status among men and women aged 15–24 in Uganda. Design The study uses data from the Uganda AIDS Indicator Survey, a cross-sectional national HIV serological study conducted in 2011. We analyzed data on 1,516 men and 2,824 women aged 15–24 who had been sexually active in the 12 months preceding the survey. Private, face-to-face interviews were also conducted to record the sociodemographics, sexual history, and experiences of sexual coercion. Logistic regression analysis was performed to measure associations between sexual behaviors and transactional sex, and associations between HIV sero-status and transactional sex. Results Among young people who had been sexually active in the 12 months prior to the survey, 5.2% of young men reported paying for sex while 3.7% of young women reported receiving gifts, favors, or money for sex. Lower educational attainment (ORadjusted 3.25, CI 1.10–9.60) and experience of sexual coercion (ORadjusted 2.83, CI 1.07–7.47) were significantly associated with paying for sex among men. Multiple concurrent sexual relationships were significantly associated with paying for sex among young men (ORadjusted 5.60, CI 2.08–14.95) and receiving something for sex among young women (ORadjusted 8.04, CI 2.55–25.37). Paying for sex among young men and having three to five lifetime sexual partners among young women were associated with increased odds of testing positive for HIV. Conclusions Transactional sex is associated with sexual coercion and HIV risk behaviors such as multiple concurrent sexual partnerships among young people in Uganda. In addition

To determine the social networking practices of directors of anesthesiology residency programs. Cross-sectional survey. Online and paper survey tool. 132 anesthesiology residency program directors in the United States. A 13-item survey including dichotomous and multiple choice responses was administered using an online survey tool and a paper survey. Data analysis was conducted by descriptive and analytical statistics (chi-square test). A P-value < 0.05 indicated statistical significance. 50% of anesthesiology program directors responded to the survey (66/132). Policies governing social networking practices were in place for 30.3% (n=20) of the programs' hospitals. The majority of program directors (81.8%, 54) reported never having had an incident involving reprimand of a resident or fellow for inappropriate social networking practices. The majority (66.7%, n=44) of responding programs reported that departments did not provide lectures or educational activities related to appropriate social networking practices. Monitoring of social networking habits of residents/fellows by program directors mainly occurs if they are alerted to a problem (54.5%, n=36). Frequent use of the Internet for conducting searches on a resident applicant was reported by 12.1% (n=8) of program directors, 30.3% (n=20) reported use a few times, and 57.6% (n=38) reported never using the Internet in this capacity. Residency programs should have a written policy related to social media use. Residency program directors should be encouraged to become familiar with the professionalism issues related to social media use in order to serve as adequate resident mentors within this new and problematic aspect of medical ethics and professionalism.

While existing research indicates that housing improvements are associated with health improvements, less is known about the wider social and health benefits of meeting national housing standards, as well as those of their specific constituent measures. This study evaluates the impacts of a managed housing upgrade programme through a repeated cross-sectional survey design. A five-wave repeated cross-sectional survey was conducted over a seven-year period from 2009 to 2016 (n = 2075; n = 2219; n = 2015; n = 1991; and n = 1709, respectively). The study followed a managed upgrade programme designed to meet a national social housing standard over an extended period. The data were analysed from a multilevel perspective to take account of the time-dependent nature of the observations and differences in socio-demographic composition. The installation of the majority of individual housing measures (new windows and doors; boilers; kitchens; bathrooms; electrics; loft insulation; and cavity/external wall insulation) were associated with improvements in several social (housing suitability, satisfaction, and quality; thermal comfort and household finances) and health (mental, respiratory and general health) outcomes; and analyses showed relationships between the number of measures installed and the total amount invested on the one hand and the social and health outcomes on the other. There were however a few exceptions. Most notably, the installation of cavity wall insulation was associated with poorer health outcomes, and did not lead to better social outcomes. Also, no association was found between the number of measures installed and respiratory health. The study suggests that substantial housing investments through a managed upgrade programme may result in better social and health outcomes, and that the size of the improvements are proportionate to the number of measures installed and amount invested. However, there may be risks associated with specific

To study the psychometric characteristics of German version of the Hospital Survey on Patient Safety Culture and to compare its dimensionality to other language versions in order to understand the instrument's potential for cross-national studies. Cross-sectional multicentre study to establish psychometric properties of German version of the survey instrument. 73 units from 37 departments of two German university hospitals. Clinical personnel (n=995 responses, response rate 39.6%). Psychometric properties (eg, model fit, internal consistency, construct validity) of the instrument and comparison of dimensionality across different language translations. The instrument demonstrated acceptable to good internal consistency (Cronbach's alpha 0.64-0.88). Confirmatory factor analysis of the original 12-factor model resulted in marginally satisfactory model fit (root mean square error of approximation (RMSEA)=0.05; standardised root mean residual (SRMR)=0.05; comparative fit index (CFI)=0.90; goodness of fit index (GFI)=0.88; Tucker-Lewis Index (TLI)=0.88). Exploratory factor analysis resulted in an alternative eight-factor model with good model fit (RMSEA=0.05; SRMR=0.05; CFI=0.95; GFI=0.91; TLI=0.94) and good internal consistency (Cronbach's alpha 0.73-0.87) and construct validity. Analysis of the dimensionality compared with models from 10 other language versions revealed eight dimensions with relatively stable composition and appearance across different versions and four dimensions requiring further improvement. The German version of Hospital Survey on Patient Safety Culture demonstrated satisfactory psychometric properties for use in German hospitals. However, our comparison of instrument dimensionality across different language versions indicates limitations concerning cross-national studies. Results of this study can be considered in interpreting findings across national contexts, in further refinement of the instrument for cross-national studies and in better

Despite the high global burden of diseases caused by tobacco, valid and comparable prevalence data for patterns of adult tobacco use and factors influencing use are absent for many low-income and middle-income countries. We assess these patterns through analysis of data from the Global Adult Tobacco Survey (GATS). Between Oct 1, 2008, and March 15, 2010, GATS used nationally representative household surveys with comparable methods to obtain relevant information from individuals aged 15 years or older in 14 low-income and middle-income countries (Bangladesh, Brazil, China, Egypt, India, Mexico, Philippines, Poland, Russia, Thailand, Turkey, Ukraine, Uruguay, and Vietnam). We compared weighted point estimates and 95% CIs of tobacco use between these 14 countries and with data from the 2008 UK General Lifestyle Survey and the 2006-07 US Tobacco Use Supplement to the Current Population Survey. All these surveys had cross-sectional study designs. In countries participating in GATS, 48·6% (95% CI 47·6-49·6) of men and 11·3% (10·7-12·0) of women were tobacco users. 40·7% of men (ranging from 21·6% in Brazil to 60·2% in Russia) and 5·0% of women (0·5% in Egypt to 24·4% in Poland) in GATS countries smoked a tobacco product. Manufactured cigarettes were favoured by most smokers (82%) overall, but smokeless tobacco and bidis were commonly used in India and Bangladesh. For individuals who had ever smoked daily, women aged 55-64 years at the time of the survey began smoking at an older age than did equivalently aged men in most GATS countries. However, those individuals who had ever smoked daily and were aged 25-34-years when surveyed started to do so at much the same age in both sexes. Quit ratios were very low (<20% overall) in China, India, Russia, Egypt, and Bangladesh. The first wave of GATS showed high rates of smoking in men, early initiation of smoking in women, and low quit ratios, reinforcing the view that efforts to prevent initiation and promote

Associations between employment status and mental health are well recognised, but evidence is sparse on the relationship between paid employment and mental health in the years running up to statutory retirement ages using robust mental health measures. In addition, there has been no investigation into the stability over time in this relationship: an important consideration if survey findings are used to inform future policy. The aim of this study is to investigate the association between employment status and common mental disorder (CMD) in 50-64-year old residents in England and its stability over time, taking advantage of three national mental health surveys carried out over a 14-year period. Data were analysed from the British National Surveys of Psychiatric Morbidity of 1993, 2000 and 2007. Paid employment status was the primary exposure of interest and CMD the primary outcome - both ascertained identically in all three surveys (CMD from the revised Clinical Interview Schedule). Multivariable logistic regression models were used. The prevalence of CMD was higher in people not in paid employment across all survey years; however, this association was only present for non-employment related to poor health as an outcome and was not apparent in those citing other reasons for non-employment. Odds ratios for the association between non-employment due to ill health and CMD were 3.05 in 1993, 3.56 in 2000, and 2.80 in 2007, after adjustment for age, gender, marital status, education, social class, housing tenure, financial difficulties, smoking status, recent physical health consultation and activities of daily living impairment. The prevalence of CMD was higher in people not in paid employment for health reasons, but was not associated with non-employment for other reasons. Associations had been relatively stable in strength from 1993 to 2007 in those three cross-sectional nationally representative samples.

To examine the association between breakfast skipping and physical activity among US adolescents aged 12-19 years. A cross-sectional study of nationally representative 2007-2008 National Health and Nutrition Examination Survey (NHANES) data. Breakfast skipping was assessed by two 24 h dietary recalls. Physical activity was self-reported by participants and classified based on meeting national recommendations for physical activity for the appropriate age group. Multiple logistic regression analysis was used to model the association between breakfast skipping and physical activity while controlling for confounders. A total of 936 adolescents aged 12-19 years in the USA. After adjusting for family income, there was no association between breakfast skipping and meeting physical activity guidelines for age among adolescents aged 12-19 years (OR = 0.95, 95% CI 0.56, 1.32). Findings from the study differ from previous research findings on breakfast skipping and physical activity. Therefore, further research that uses large, nationally representative US samples and national recommended guidelines for physical activity is needed.

To describe data from the National Health Interview Survey (NHIS), both the annual core survey and periodic occupational health supplements (OHSs), available for examining national trends in worker health. The NHIS is an annual in-person household survey with a cross-sectional multistage clustered sample design to produce nationally representative health data. The 2010 NHIS included an OHS. Prevalence rates of various health conditions and health behaviors among workers based on multiple years of NHIS core data are available. In addition, the 2010 NHIS-OHS data provide prevalence rates of selected health conditions, work organization factors, and occupational exposures among US workers by industry and occupation. The publicly available NHIS data can be used to identify areas of concern for various industries and for benchmarking data from specific worker groups against national averages.

Context The scarcity of cross-national reports and the changes in DSM-5 regarding panic disorder (PD) and panic attacks (PAs) call for new epidemiological data on PD and PAs and its subtypes in the general population. Objective To present representative data about the cross-national epidemiology of PD and PAs in accordance with DSM-5 definitions. Design and Setting Nationally representative cross-sectional surveys using the World Health Organization Composite International Diagnostic Interview version 3.0. Participants Respondents (n=142,949) from 25 high, middle and lower-middle income countries across the world aged 18 years or older. Main Outcome Measures PD and presence of single and recurrent PAs. Results Lifetime prevalence of PAs was 13.2% (s.e. 0.1%). Among persons that ever had a PA, the majority had recurrent PAs (66.5%; s.e. 0.5%), while only 12.8% fulfilled DSM-5 criteria for PD. Recurrent PAs were associated with a subsequent onset of a variety of mental disorders (OR 2.0; 95% CI 1.8–2.2) and their course (OR 1.3; 95% CI 1.2–2.4) whereas single PAs were not (OR 1.1; 95% CI 0.9–1.3 and OR 0.7; 95% CI 0.6–0.8). Cross-national lifetime prevalence estimates were 1.7% (s.e. 0.0%) for PD with a median age of onset of 32 (IQR 20–47). Some 80.4% of persons with lifetime PD had a lifetime comorbid mental disorder. Conclusions We extended previous epidemiological data to a cross-national context. The presence of recurrent PAs in particular is associated with subsequent onset and course of mental disorders beyond agoraphobia and PD, and might serve as a generic risk marker for psychopathology.

Transportation assimilation revisited: New evidence from repeated cross-sectional survey data

PubMed Central

2018-01-01

Background Based on single cross-sectional data, prior research finds evidence of “transportation assimilation” among U.S. immigrants: the length of stay in the U.S. is negatively correlated with public transit use. This paper revisits this question by using repeated cross-sectional data, and examines the trend of transportation assimilation over time. Methods and results Using 1980, 1990, 2000 1% census and 2010 (1%) American Community Survey, I examine the relationship between the length of stay in the U.S. and public transit ridership among immigrants. I first run regressions separately in four data sets: I regress public transit ridership on the length of stay, controlling for other individual and geographic variables. I then compare the magnitudes of the relationship in four regressions. To study how the rate of transportation assimilation changes over time, I pool the data set and regress public transit ridership on the length of stay and its interactions with year dummies to compare the coefficients across surveys. Results confirm the conclusion of transportation assimilation: as the length of stay in the U.S. increases, an immigrant’s public transit use decreases. However, the repeated cross-section analysis suggests the assimilation rate has been decreasing in the past few decades. Conclusions This paper finds evidence of transportation assimilation: immigrants become less likely to ride public transit as the length of stay in the U.S. increases. The assimilation rate, however, has been decreasing over time. This paper finds that the rate of public transit ridership among new immigrants upon arrival, the geographic distribution of immigrants, and the changing demographics of the U.S. immigrants play roles in affecting the trend of transportation assimilation.

Objective To examine associations between the contract and ownership type of general practices and patient experience in England. Design Multilevel linear regression analysis of a national cross-sectional patient survey (General Practice Patient Survey). Setting All general practices in England in 2013-2014 ( n = 8017). Participants 903,357 survey respondents aged 18 years or over and registered with a general practice for six months or more (34.3% of 2,631,209 questionnaires sent). Main outcome measures Patient reports of experience across five measures: frequency of consulting a preferred doctor; ability to get a convenient appointment; rating of doctor communication skills; ease of contacting the practice by telephone; and overall experience (measured on four- or five-level interval scales from 0 to 100). Models adjusted for demographic and socioeconomic characteristics of respondents and general practice populations and a random intercept for each general practice. Results Most practices had a centrally negotiated contract with the UK government ('General Medical Services' 54.6%; 4337/7949). Few practices were limited companies with locally negotiated 'Alternative Provider Medical Services' contracts (1.2%; 98/7949); these practices provided worse overall experiences than General Medical Services practices (adjusted mean difference -3.04, 95% CI -4.15 to -1.94). Associations were consistent in direction across outcomes and largest in magnitude for frequency of consulting a preferred doctor (-12.78, 95% CI -15.17 to -10.39). Results were similar for practices owned by large organisations (defined as having ≥20 practices) which were uncommon (2.2%; 176/7949). Conclusions Patients registered to general practices owned by limited companies, including large organisations, reported worse experiences of their care than other patients in 2013-2014.

To assess whether following standardisation of tobacco packaging in Australia, smokers were, as predicted by the tobacco industry, more likely to use illicit tobacco. National cross-sectional telephone surveys conducted continuously from April 2012 (6 months before implementation of plain packaging (PP)) to March 2014 (15 months after) using responses from current cigarette smokers (n=8679). Changes between pre-PP, the transition to PP and PP phase were examined using logistic regression models. Among those whose factory-made cigarettes were purchased in Australia, compared with pre-PP, there were no significant increases in the PP phase in use of: 'cheap whites' (<0.1%; OR=0.24, 95% CI 0.04 to 1.56, p=0.134); international brands purchased for 20% or more below the recommended retail price (0.2%; OR=3.49, 95% CI 0.66 to 18.35, p=0.140); or packs purchased from informal sellers (<0.1%; OR=0.24, 95% CI 0.04 to 1.47, p=0.124). The prevalence of any use of unbranded illicit tobacco remained at about 3% (adjusted OR=0.79, 95% CI 0.58 to 1.08, p=0.141). While unable to quantify the total extent of use of illicit manufactured cigarettes, in this large national survey we found no evidence in Australia of increased use of two categories of manufactured cigarettes likely to be contraband, no increase in purchase from informal sellers and no increased use of unbranded illicit 'chop-chop' tobacco.

2008-11-01

The aim of this national cross-sectional survey was to draw information on pain prevalence and intensity from a large sample of patients who were admitted to oncologic centres for different reasons and to evaluate the pain treatment and possible influencing factors. A total of 2,655 patients completed the study. Nine hundred and one patients (34%) reported pain. Higher pain levels were observed in inpatients, in the presence of bone metastases, and with low levels of Eastern Cooperative Oncology Group status. The number of patients receiving strong opioids increased with the highest levels of pain. However, a significant part of patients with moderate-severe pain were not receiving appropriate medication, patients being predominantly administered non-opioid drugs. General practitioners' attitudes did not negatively influence the opioid prescription. The results of this survey indicate a need for continuing educational and informative program in pain management for oncologists and more generally for any physician dealing with cancer patients.

The chiropractic scope of practice in the United States: a cross-sectional survey.

Chang, Mabel

2014-01-01

The purpose of this study was to assess the current status of chiropractic practice laws in the United States. This survey is an update and expansion of 3 original surveys conducted in 1987, 1992, and 1998. A cross-sectional survey of licensure officials from the Federation of Chiropractic Licensing Boards e-mail list was conducted in 2011 requesting information about chiropractic practice laws and 97 diagnostic, evaluation, and management procedures. To evaluate content validity, the survey was distributed in draft form at the fall 2010 Federation of Chiropractic Licensing Boards regional meeting to regulatory board members and feedback was requested. Comments were reviewed and incorporated into the final survey. A duplicate question was imbedded in the survey to test reliability. Partial or complete responses were received from 96% (n = 51) of the jurisdictions in the United States. The states with the highest number of services that could be performed were Missouri (n = 92), New Mexico (n = 91), Kansas (n = 89), Utah (n = 89), Oklahoma (n = 88), Illinois (n = 87), and Alabama (n = 86). The states with the highest number of services that cannot be performed are New Hampshire (n = 49), Hawaii (n = 47), Michigan (n = 42), New Jersey (n = 39), Mississippi (n = 39), and Texas (n = 30). The scope of chiropractic practice in the United States has a high degree of variability. Scope of practice is dynamic, and gray areas are subject to interpretation by ever-changing board members.

Objective To examine associations between the contract and ownership type of general practices and patient experience in England. Design Multilevel linear regression analysis of a national cross-sectional patient survey (General Practice Patient Survey). Setting All general practices in England in 2013–2014 (n = 8017). Participants 903,357 survey respondents aged 18 years or over and registered with a general practice for six months or more (34.3% of 2,631,209 questionnaires sent). Main outcome measures Patient reports of experience across five measures: frequency of consulting a preferred doctor; ability to get a convenient appointment; rating of doctor communication skills; ease of contacting the practice by telephone; and overall experience (measured on four- or five-level interval scales from 0 to 100). Models adjusted for demographic and socioeconomic characteristics of respondents and general practice populations and a random intercept for each general practice. Results Most practices had a centrally negotiated contract with the UK government (‘General Medical Services’ 54.6%; 4337/7949). Few practices were limited companies with locally negotiated ‘Alternative Provider Medical Services’ contracts (1.2%; 98/7949); these practices provided worse overall experiences than General Medical Services practices (adjusted mean difference −3.04, 95% CI −4.15 to −1.94). Associations were consistent in direction across outcomes and largest in magnitude for frequency of consulting a preferred doctor (−12.78, 95% CI −15.17 to −10.39). Results were similar for practices owned by large organisations (defined as having ≥20 practices) which were uncommon (2.2%; 176/7949). Conclusions Patients registered to general practices owned by limited companies, including large organisations, reported worse experiences of their care than other patients in 2013–2014.

Given the rising profile of the Alexander Technique in the UK, there is a need for a comprehensive description of its teachers and of those who currently take lessons. In a national survey of Alexander teachers, we set out to address this information gap. A cross-sectional survey of 871 UK members of three main Alexander Technique teachers' professional associations was conducted. A questionnaire requested information about their professional background, teaching practice and methods, and about the people who attend lessons and their reasons for seeking help. With an overall response rate of 61%, 534 teachers responded; 74% were female with median age of 58 years, 60% had a higher education qualification, and 95% were self-employed, many with additional non-Alexander paid employment. The majority (87%) offered lessons on their own premises or in a privately rented room, and 19% provided home visits; both individual and group lessons were provided. People who took lessons were predominantly female (66%) with a median age of 48 years, and 91% paid for their lessons privately. Nearly two-thirds (62%) began lessons for reasons related to musculoskeletal conditions, including back symptoms, posture, neck pain, and shoulder pain. Other reasons were general (18%, including well-being), performance-related (10%, including voice-, music-, and sport-related), psychological (5%) and neurological (3%). We estimate that Alexander teachers in the UK provide approximately 400,000 lessons per year. This study provides an overview of Alexander Technique teaching in the UK today and data that may be useful when planning future research. Copyright © 2015 Elsevier Ltd. All rights reserved.

Influenza vaccination, inverse care and homelessness: cross-sectional survey of eligibility and uptake during the 2011/12 season in London

PubMed Central

2014-01-01

Background Influenza vaccination eligibility and uptake among homeless adults has not been previously assessed in the UK. This cross-sectional survey aimed to measure the proportion of homeless people visited by an NHS outreach service (Find and Treat) who were eligible for and had received vaccination during 2011/12. Methods A cross-sectional survey was carried out in 27 separate homeless hostels, day centres and drug services in London between July and August in 2012. Eligibility for the survey was by virtue of being in attendance at one of 27 venues visited by Find and Treat. No specific exclusion criteria were used. Results 455 clients took part in the survey out of 592 approached (76.9%). A total of 190 homeless people (41.8%; 95% CI: 34.5,50.5) were eligible for influenza vaccination. In those aged 16–64, eligibility due to clinical risk factors was 38.9% (95% CI: 31.5,48.2). Uptake of vaccination in homeless 16–64 year olds with a clinical risk factor during the 2011/12 influenza season was 23.7% (95% CI: 19.8,28.3) compared to national levels of 53.2% (excluding pregnant women). In those aged over 65, uptake was 42.9% (95% CI: 16.7,100.0) compared with 74.0% nationally. Conclusions This study demonstrates that the homeless population have high levels of chronic health problems predisposing them to severe complications of influenza, but vaccine uptake levels that are less than half those seen among eligible GP patient groups in England. It provides a clear example of the health inequalities and inverse care law that impact this population. The results of this study provide strong justification for intensifying efforts to ensure homeless people have access to influenza vaccination. PMID:24433371

Trends in overweight and obesity in Lebanon: evidence from two national cross-sectional surveys (1997 and 2009)

PubMed Central

2012-01-01

Background Even though the obesity epidemic continues to grow in various parts of the world, recent reports have highlighted disparities in obesity trends across countries. There is little empirical evidence on the development and growth of obesity in Lebanon and other countries of the Eastern Mediterranean Region. Acknowledging the need for effective obesity preventive measures and for accurate assessment of trends in the obesity epidemic, this study aims at examining and analyzing secular trends in the prevalence of overweight and obesity over a 12-year period in Lebanon. Methods Based on weight and height measurements obtained from two national cross-sectional surveys conducted in 1997 and 2009 on subjects 6 years of age and older, BMI was calculated and the prevalence of obesity was determined based on BMI for adults and BMI z-scores for children and adolescents, according to WHO criteria. Age -and sex- adjusted odds ratios for overweight and obesity were determined, with the 1997 year as the referent category. Annual rates of change in obesity prevalence per sex and age group were also calculated. Results The study samples included a total of 2004 subjects in the 1997 survey and 3636 in the 2009 survey. Compared to 1997, mean BMI values were significantly higher in 2009 among all age and sex groups, except for 6–9 year old children. Whereas the prevalence of overweight appeared stable over the study period in both 6–19 year old subjects (20.0% vs. 21.2%) and adults aged 20 years and above (37.0% vs. 36.8%), the prevalence of obesity increased significantly (7.3% vs. 10.9% in 6–19 year olds; 17.4% vs. 28.2% in adults), with the odds of obesity being 2 times higher in 2009 compared to 1997, in both age groups (OR = 1.96, 95% CI:1.29-2.97 and OR = 2.01, 95% CI: 1.67-2.43, respectively). The annual rates of change in obesity prevalence ranged between +4.1% in children and adolescents and +5.2% in adults. Conclusion The study’s findings highlight an

Despite advances in the management of chronic kidney disease (CKD), there is ongoing uncertainty regarding the prevalence of CKD in postmenopausal women. This study was designed to investigate both CKD prevalence and related risk factors in a cohort of postmenopausal Chinese women. A cross-sectional survey was administered to a nationally representative sample of female Chinese participants, including a total of 47,204 subjects, among whom were 8573 self-reported postmenopausal women. CKD was defined as either an estimated glomerular filtration rate (eGFR) of <60 mL/min/1.73 m2 body surface area or else the presence of albuminuria. All subjects completed a questionnaire that included items related to their lifestyles and medical histories. Data were collected on blood pressure, serum creatinine, urinary albumin, and urinary creatinine. Risk factors correlated with the presence of CKD were analyzed using logistic regression analysis. Results showed that the adjusted prevalence of an eGFR of < 60 mL/min/1.73 m2 among this postmenopausal survey cohort was 5.3% (95% confidence interval: 4.7-6.1) and of albuminuria, 12.4% (11.7-13.1). The overall prevalence of CKD in this postmenopausal cohort was 16.6% (15.8-17.4). Factors associated with kidney pathology included nephrotoxic drug use, history of cardiovascular disease, hyperuricemia, hypertension, and diabetes (the lower limit of multivariable adjusted odds ratios > 1). The current study revealed a high prevalence of CKD in Chinese postmenopausal women. These results provide baseline data for disease prevention and treatment.

To describe the sexual behaviour and related risk of a sample of dance drug users and compare this with data from the UK National Survey of Sexual Attitudes and Lifestyles 2000 survey. Cross-sectional purposive sampling using both self-completion postal and web-based questionnaires. This sample of dance drug users are more sexually active and have more concurrent partners than the general population. Rates of anal or vaginal sex within the last year without condom use are high and of concern (men 80 per cent; women 90 per cent). These dance drug users appear also to have higher lifetime prevalence of sexually transmitted infections than the general population and are also more likely to have ever attended a sexual health clinic. Clubbing and dance drug use, as part of a socially active lifestyle, is associated with elevated and pronounced sexual health risk. Future epidemiological studies of sexual health risk should incorporate investigation of both clubbing and recreational drug use in order to confirm the representativeness of these observations. Clubbers should be considered a target for dedicated sexual health promotion interventions, which may also be combined with interventions targeting drug and alcohol use.

Clinicians often ask pregnant women about tobacco smoking, but their practices of asking about other smoking and nicotine exposures are unknown. This study analysed how often clinicians ask pregnant women about their use of e-cigarettes, cannabis, chewing tobacco, and second-hand smoke (SHS) exposure. Two cross-sectional surveys were undertaken. A random sample of 500 General Practitioner (GP) members were invited from the National Faculty of Aboriginal and Torres Strait Islander Health (NFATSIH) to complete an on-line survey, and 5571 GP and Obstetrician (OBS) members of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) were sent a paper survey by mail. Questions on frequency of asking about the exposures used Likert Scales, later dichotomized to "often-always" and "never-sometimes". Logistic regressions estimated associations between clinician type and asking about cannabis, e-cigarettes, chewing tobacco, and SHS. An adjusted model reduced potential confounders of location, guidelines, gender and population. n = 378 GPs and OBS participated (6.2% response). In total, 13-14% asked "often-always" about e-cigarettes; 58% cannabis; 38% cannabis with tobacco; 27% SHS, and 10% chewing tobacco-compared to 95% of the sample asking about cigarette smoking. After adjustment, the odds of RANZCOG GPs (OR 0.34) and OBS (OR 0.63) asking about cannabis were lower compared to NFATSIH GPs. Clinician type was non-significant for asking about e-cigarettes, chewing tobacco and SHS. Surveyed Australian GPs and obstetricians asked less frequently about e-cigarettes, chewing, SHS exposure, and cannabis, potentially missing important exposures for mother and child.

Despite high-level evidence of the benefits of caseload midwifery for women and babies, little is known about specific practice arrangements, organisational barriers and facilitators, nor about workforce requirements of caseload. This paper explores how caseload models across Australia operate. A national cross-sectional, online survey of maternity managers in public maternity hospitals with birthing services was undertaken. Only services with a caseload model are included in the analysis. Of 253 eligible hospitals, 149 (63%) responded, of whom 44 (31%) had a caseload model. Operationalisation of caseload varied across the country. Most commonly, caseload midwives were required to work more than 0.5 EFT, have more than one year of experience and have the skills across the whole scope of practice. On average, midwives took a caseload of 35-40 women when full time, with reduced caseloads if caring for women at higher risk. Leave coverage was complex and often ad-hoc. Duration of home-based postnatal care varied and most commonly provided to six weeks. Women's access to caseload care was impacted by many factors with geographical location and obstetric risk being most common. Introducing, managing and operationalising caseload midwifery care is complex. Factors which may affect the expansion and availability of the model are multi-faceted and include staffing and model inclusion guidelines. Coverage of leave is a factor which appears particularly challenging and needs more focus. Copyright © 2017 Australian College of Midwives. Published by Elsevier Ltd. All rights reserved.

Background Quality indicators for primary care focus predominantly on the public health model and organisational measures. Patient experience is an important dimension of quality. Accreditation for GP training practices requires demonstration of a series of attributes including patient-centred care. Aim The national GP Patient Survey (GPPS) was used to determine the characteristics of general practices scoring highly in responses relating to the professional skills and characteristics of doctors. Specifically, to determine whether active participation in postgraduate GP training was associated with more positive experiences of care. Design and setting Retrospective cross-sectional study in general practices in England. Method Data were obtained from the national QOF dataset for England, 2011/12 (8164 general practices); the GPPS in 2012 (2.7 million questionnaires in England; response rate 36%); general practice and demographic characteristics. Sensitivity analyses included local data validated by practice inspections. Outcome measures: multilevel regression models adjusted for clustering. Results GP training practice status (29% of practices) was a significant predictor of positive GPPS responses to all questions in the ‘doctor care’ (n = 6) and ‘overall satisfaction’ (n = 2) domains but not to any of the ‘nurse care’ or ‘out-of-hours’ domain questions. The findings were supported by the sensitivity analyses. Other positive determinants were: smaller practice and individual GP list sizes, more older patients, lower social deprivation and fewer ethnic minority patients. Conclusion Based on GPPS responses, doctors in GP training practices appeared to offer more patient-centred care with patients reporting more positively on attributes of doctors such as ‘listening’ or ‘care and concern’.

Pregnancy-related low back pain (LBP) is very common. Evidence from a systematic review supports the use of exercise and acupuncture, although little is known about the care received by women with pregnancy-related back pain in the U.K. To describe current acupuncture and standard care management of pregnancy-related LBP by U.K. physiotherapists. Cross-sectional survey of physiotherapists with experience of treating women with pregnancy-related LBP from three professional networks of the Chartered Society of Physiotherapy. In total, 1093 physiotherapists were mailed a questionnaire. The questionnaire captured respondents' demographic and practice setting information, and experience of managing women with pregnancy-related back pain, and investigated the reported management of pregnancy-related LBP using a patient case vignette of a specific, 'typical' case. The overall response rate was 58% (629/1093). Four hundred and ninety-nine physiotherapists had experience of treating women with pregnancy-related LBP and were included in the analysis. Most respondents worked wholly or partly in the U.K. National Health Service (78%). Most respondents reported that they treat patients with pregnancy-related LBP in three to four one-to-one treatment sessions over 3 to 6 weeks. The results show that a range of management strategies are employed for pregnancy-related LBP, and multimodal management is common. The most common reported treatment was home exercises (94%), and 24% of physiotherapists reported that they would use acupuncture with the patient described in the vignette. This study provides the first robust data on the management of pregnancy-related LBP by U.K. physiotherapists. Multimodal management is common, although exercise is the most frequently used treatment for pregnancy-related LBP. Acupuncture is used less often for this patient group.

The aim of this study was to determine the prevalence of workplace bullying among junior doctors in Pakistan, identify the types and sources of bullying behaviours and investigate the perceived barriers to making complaints against bullying. We conducted a cross-sectional survey of junior doctors using convenience sampling in three tertiary care hospitals in two provinces of Pakistan. Demographic details and information about the different types of bullying behaviours experienced by junior doctors in the 12 months preceding the study were collected using a previously validated list of 20 such behaviours. Respondents were also asked to indicate the sources of bullying, any complaints made and if not, the reasons behind it. The data was analysed using the Statistical Package for the Social Sciences. A total of 654 doctors participated in the study. 417 (63.8 percent) of them reported experiencing one or more type of bullying in the past 12 months. 436 (66.7 percent) doctors had witnessed the bullying of others. The most common source of bullying was consultants (51.6 percent). 306 (73.4 percent) respondents did not make a complaint against the bullying. Bullying is faced by a fairly large proportion of junior doctors in Pakistan. The most frequent perpetrators of this bullying are consultants. Major changes are required at the national, organisational and individual levels in Pakistan to tackle the bullying problem and prevent its adverse consequences in an already vulnerable healthcare delivery system.

More than 27,000 Australians currently live with HIV. Most of these people have access to quality clinical care and antiretroviral treatment (ART) and can expect good general health. However, HIV-related stigma is a problem and many people living with HIV experience poorer than average mental health. Issues of aging are also of increasing concern. This paper describes the methods and sample for the HIV Futures 8 study, a national survey of people living with HIV in Australia that aimed to identify factors that support health and well-being among this population. HIV Futures 8 forms part of a series of cross-sectional surveys (The "HIV Futures" studies) that have been repeated periodically since 1997. In the most recent survey, participants were able to opt into a prospective longitudinal study. HIV Futures 8 was open to people aged over 17 who were living with HIV. Data were collected in 2015/2016 using a self-complete survey that contained approximately 250 items related to physical and mental health, use of ART, HIV exposure and testing, financial security, social connectedness, relationships, life satisfaction, resilience, stigma, use of health and support services, and health literacy. To enable comparison of cross-sectional data over time, questionnaire items were consistent with those used in previous HIV Futures surveys. In HIV Futures 8, participants were invited to volunteer coded information that will allow longitudinal follow-up when participants complete subsequent HIV Futures surveys. The survey was advertised through the networks of HIV organizations, on social media and through HIV clinics and services. HIV Futures 8 was completed by 895 participants. This represents approximately 3.8% of the total number of people living with diagnosed HIV in Australia in 2014. Findings from HIV Futures 8 will contribute important insights into the complexity of factors that support physical and mental well-being among people living with HIV. The findings will also

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

To assess the level of professional satisfaction amongst family physicians of Pakistan and to identify the factors associated with professional dissatisfaction. The study was part of a larger national survey for "Status of PostgraduateTraining and Continuing Medical Education of Family Physicians in Pakistan" which was a cross-sectional, postal survey of family physicians conducted over 10 months between November 2009 and September 2010. The main outcome variables were professional satisfaction, as well as reasons for professional satisfaction and dissatisfaction. SPSS 17 was used for data analysis. Multivariable logistic regression was used to determine factors associated with professional dissatisfaction. Of the total 1200 survey forms distributed, 288 (24%) were received back. The mean age of the participants was 37 +/- 9 years with a range between 26 and 72 years. Of the total, 226 (78.5%) were males. Overall, 213 (74%) family physicians were satisfied with their profession. The factors significantly associated with professional dissatisfaction included the participants opinion that they were not respected by the public (OR: 11.6, C.I: 1.9-71.5); as well as regretting being a doctor (OR:62.9, C.I: 8.4-469.8). Most of the family physicians had professional satisfaction, but a minority had regrets about being a doctor and were dissatisfied over how their profession affected their family life. Further research may be needed to study work-life balance amongst family physicians of Pakistan.

This cross-sectional multilevel study aimed to investigate the relationship between improvement of the work environment and work-related stress in a nationally representative sample in Japan. The study was based on a national survey that randomly sampled 1745 worksites and 17,500 nested employees. The survey asked the worksites whether improvements of the work environment were conducted; and it asked the employees to report the number of work-related stresses they experienced. Multilevel multinominal logistic and linear regression analyses were conducted. Improvement of the work environment was not significantly associated with any level of work-related stress. Among men, it was significantly and negatively associated with the severe level of work-related stress. The association was not significant among women. Improvements to work environments may be associated with reduced work-related stress among men nationwide in Japan.

To describe the state of the public and private malaria diagnostics market shortly after WHO updated its guidelines for testing all suspected malaria cases prior to treatment. Ten nationally representative cross-sectional cluster surveys were conducted in 2011 among public and private health facilities, community health workers and retail outlets (pharmacies and drug shops) in nine countries (Tanzania mainland and Zanzibar surveyed separately). Eligible outlets had antimalarials in stock on the day of interview or had stocked antimalarials in the past 3 months. Three thousand four hundred and thirty-nine rapid diagnostic test (RDT) products from 39 manufacturers were audited among 12,197 outlets interviewed. Availability was typically highest in public health facilities, although availability in these facilities varied greatly across countries, from 15% in Nigeria to >90% in Madagascar and Cambodia. Private for-profit sector availability was 46% in Cambodia, 20% in Zambia, but low in other countries. Median retail prices for RDTs in the private for-profit sector ranged from $0.00 in Madagascar to $3.13 in Zambia. The reported number of RDTs used in the 7 days before the survey in public health facilities ranged from 3 (Benin) to 50 (Zambia). Eighteen months after WHO updated its case management guidelines, RDT availability remained poor in the private sector in sub-Saharan Africa. Given the ongoing importance of the private sector as a source of fever treatment, the goal of universal diagnosis will not be achievable under current circumstances. These results constitute national baselines against which progress in scaling-up diagnostic tests can be assessed. © 2015 John Wiley & Sons Ltd.

No global consensus: a cross-sectional survey of maternal weight policies

PubMed Central

2014-01-01

Background Growing evidence suggests that maternal prepregnancy weight and gestational weight gain are risk factors for perinatal complications and subsequent maternal and child health. Postpartum weight retention is also associated with adverse birth outcomes and maternal obesity. Clinical guidelines addressing healthy weight before, during, and after pregnancy have been introduced in some countries, but at present a systematic accounting for these policies has not been conducted. The objective of the present study was to conduct a cross-national comparison of maternal weight guidelines. Methods This cross sectional survey administered a questionnaire online to key informants with expertise on the subject of maternal weight to assess the presence and content of preconceptional, pregnancy and postpartum maternal weight guidelines, their rationale and availability. We searched 195 countries, identified potential informants in 80 and received surveys representing 66 countries. We estimated the proportion of countries with guidelines by region, income, and formal or informal policy, and described and compared guideline content, including a rubric to assess presence or absence of 4 guidelines: encourage healthy preconceptional weight, antenatal weighing, encourage appropriate gestational gain, and encourage attainment of healthy postpartum weight. Results Fifty-three countries reported either a formal or informal policy regarding maternal weight. The majority of these policies included guidelines to assess maternal weight at the first prenatal visit (90%), to monitor gestational weight gain during pregnancy (81%), and to provide recommendations to women about healthy gestational weight gain (62%). Guidelines related to preconceptional (42%) and postpartum (13%) weight were less common. Only 8% of countries reported policies that included all 4 fundamental guidelines. Guideline content and rationale varied considerably between countries, and respondents perceived that

This study was undertaken to examine factors relating to adolescent suicide behavior. This was a cross-sectional school survey of 4,500 adolescent students based on a structured questionnaire. Data were collected using the supervised self-administered questionnaire (modified version of the Youth Risk Behavior Surveillance in the Malaysian National Language, Bahasa Malaysia). Seven percent (312 of 4,454) of the adolescent students had seriously considered attempting suicide. Among the adolescents, 4.6% had attempted suicide at least once during the 12 months preceding the survey. Female adolescents were more likely to put their suicidal thoughts into suicidal action than were male adolescents. Malay and Indian people are more likely than the Chinese to respond, "Felt sad and hopeless." However, Malay adolescents had the lowest rate of attempted suicide. Based on multiple logistic regression, factors significantly related to urban adolescents' suicide behavior are "Felt sad or hopeless," "Number of days felt unsafe to go to school," "Riding with a driver who had been drinking alcohol," "Physical fight," and "Number of days absent from school." In comparison, factors relating to rural adolescents' suicide behavior are "Felt sad or hopeless," "Physical fight," "Physical fight resulting in injury," and "Drive a vehicle after drinking alcohol." Adolescent suicide behavior should be viewed as a serious problem. Measures can be taken to prevent suicide by looking at the factors significantly linked to suicidal behavior among adolescents. Steps can then be taken to identify adolescents who have serious suicidal ideation so that intervention can be taken to reduce the suicidal rate.

Flaws in previous studies mean that findings of J-shaped risk curves for gambling should be disregarded. The current study aims to estimate the shape of risk curves for gambling losses and risk of gambling-related harm (a) for total gambling losses and (b) disaggregated by gambling activity. Four cross-sectional surveys. Nationally representative surveys of adults in Australia (1999), Canada (2000), Finland (2011) and Norway (2002). A total of 10 632 Australian adults, 3120 Canadian adults, 4484 people aged 15-74 years in Finland and 5235 people aged 15-74 years in Norway. Problem gambling risk was measured using the modified South Oaks Gambling Screen, the NORC DSM Screen for Gambling Problems and the Problem Gambling Severity Index. Risk curves for total gambling losses were estimated to be r-shaped in Australia {β losses = 4.7 [95% confidence interval (CI) = 3.8, 6.5], β losses(2 =)  -7.6 (95% CI = -17.5, -4.5)}, Canada [β losses = 2.0 (95% CI = 1.3, 3.9), β losses(2 =)  -3.9 (95% CI = -15.4, -2.2)] and Finland [β losses = 3.6 (95% CI = 2.5, 7.5), β losses(2 =)  -4.4 (95% CI = -34.9, -2.4)] and linear in Norway [β losses = 1.6 (95% CI = 0.6, 3.1), β losses(2 =)  -2.6 (95% CI = -12.6, 1.4)]. Risk curves for different gambling activities showed either linear, r-shaped or non-significant relationships. Player loss-risk curves for total gambling losses and for different gambling activities are likely to be linear or r-shaped. For total losses and electronic gaming machines, there is no evidence of a threshold below which increasing losses does not increase the risk of harm. © 2015 Society for the Study of Addiction.

Objectives: Good maternal health and fetal development require sufficient and good quality of sleep during pregnancy. This study investigated sleep duration and quality in pregnant women, assessing factors with possibly influence on sleep. Method: A cross-sectional survey was conducted on pregnant women between June and August in 2015 in 16 hospitals in five provinces in China. A total of 2345 pregnant women aged 18 years and older were surveyed. Insufficient sleeping duration was defined as sleeping of less than 7 h per day. Excessive sleep duration was defined as sleeping of more than 9 h per day. Results: A total of 561 (23.9%) participants reported insufficient sleeping duration, whereas 485 (20.9%) claimed excessive sleep duration. A total of 358 (15.2%) of pregnant women reported problems regarding sleep quality. Compared to pregnant women with sufficient sleeping duration, those with insufficient sleeping duration were prone to have poor sleep quality, whereas those with excessive sleeping duration featured low possibility of poor sleep quality. High-risk groups of insufficient sleep duration include women of Han nationality, with siblings, in their first trimester of pregnancy, receiving care in low-capacity/quality hospital settings, and with daily or 1-3 days of secondhand smoke exposure. High-risk groups of excessive sleep duration include women living in rural areas, unemployed, in their third trimester of pregnancy, and receiving care in medium-capacity/quality hospital settings. High-risk groups of poor sleep quality include women of non-Han nationality, low income level, in their third trimester of pregnancy, and with insufficient sleep duration. Conclusions: Insufficient/excessive sleep duration and poor sleep quality commonly occur during pregnancy in China. Findings provide a better understanding of the influencing factors of insufficient/excessive sleep duration and poor quality of sleep. These findings have some implications for future

South Africa is one of the 22 high tuberculosis burden countries that contribute 80% of the global tuberculosis cases. Tuberculosis is infectious and due to its rapid and easy transmission route poses a threat to population health. Considering the importance of social and psychological factors in influencing health outcomes, appraising knowledge and awareness of tuberculosis, remain vital for effective tuberculosis control. The main aim of this study was to investigate the factors that predict knowledge about tuberculosis among 18-64 year old adults in South Africa. A cross-sectional survey method was used. Multi-stage disproportionate, stratified cluster sampling was used to select households within enumeration areas stratified by province and locality type. Based on the Human Sciences Research Council 2007 master sample, 500 Enumerator Areas representative of the socio-demographic profile of South Africa were identified and a random sample of 20 households was randomly selected from each Enumerator Area, yielding an overall sample of 10,000 households. The tuberculosis module contained in the South African National Health And Nutrition Examination Survey I was the only module that examined the social determinants of an infectious disease. This module was questionnaire-based with no biomarkers obtained to screen for the presence of tuberculosis disease among the participants. Data was collected by administering a researcher developed individual level questionnaire. Simple and multiple linear regression was used to determine the independent variables associated with tuberculosis knowledge. Half the sample (52.6%) was female and the majority of the respondents were black African (76.5%). More than two thirds (68.0%) resided in urban areas, 56.9% did not complete high school and half were not in formal employment. Significant predictors of tuberculosis knowledge were race, sex, completion of high school, being in employment, having a diagnosis of the disease in ones

Objective To assess life-saving and disability-preventing surgical services (including emergency, trauma, obstetrics, anaesthesia) of health facilities in Somalia and to assist in the planning of strategies for strengthening surgical care systems. Design Cross-sectional survey. Setting Health facilities in all 3 administrative zones of Somalia; northwest Somalia (NWS), known as Somaliland; northeast Somalia (NES), known as Puntland; and south/central Somalia (SCS). Participants 14 health facilities. Measures The WHO Tool for Situational Analysis to Assess Emergency and Essential Surgical Care was employed to capture a health facility's capacity to deliver surgical and anaesthesia services by investigating four categories of data: infrastructure, human resources, interventions available and equipment. Results The 14 facilities surveyed in Somalia represent 10 of the 18 districts throughout the country. The facilities serve an average patient population of 331 250 people, and 12 of the 14 identify as hospitals. While major surgical procedures were provided at many facilities (caesarean section, laparotomy, appendicectomy, etc), only 22% had fully available oxygen access, 50% fully available electricity and less than 30% had any management guidelines for emergency and surgical care. Furthermore, only 36% were able to provide general anaesthesia inhalation due to lack of skills, supplies and equipment. Basic supplies for airway management and the prevention of infection transmission were severely lacking in most facilities. Conclusions According to the results of the WHO Tool for Situational Analysis to Assess Emergency and Essential Surgical Care survey, there exist significant gaps in the capacity of emergency and essential surgical services in Somalia including inadequacies in essential equipment, service provision and infrastructure.

Anxiety and depression are common in the perinatal period. Telephone interventions, including telephone peer support and counselling, have been developed to support those experiencing perinatal mental illness. PANDA Post and Antenatal Depression Association provides support to women and men experiencing perinatal mental illness via the Australian National Perinatal Depression Helpline, encompassing both volunteer peer support and professional counselling. This study aimed to explore the experiences of callers to the Helpline. A cross-sectional survey design was used. All new callers from 1(st) May to 30(th) September 2013 were invited to participate. The survey, adapted from a previous survey of PANDA callers, included 23 questions using Likert-type scales, demographic and open-ended questions. Thematic network analysis was undertaken for responses to open-ended questions. 124 responses were received (124/405; 30% response). The majority of callers had called the Helpline regarding themselves (90%), with over one third (33%) of all callers seeking crisis support and help. Ninety-nine per cent of respondents 'agreed' or 'strongly agreed' that staff and/or volunteers understood their concerns, and 97% 'agreed' or 'strongly agreed' that overall PANDA had helped them. Callers described the PANDA service as uniquely tailored to the perinatal period, providing accessible, non-judgemental understanding and support, with a global theme from open-ended comments describing PANDA as 'a safe space to be heard and receive support without judgement'. Recommendations for service changes included increased hours of availability. Callers reported positive experiences of accessing support from the PANDA National Perinatal Depression Helpline. The Helpline was described as an accessible and acceptable telephone support for individuals experiencing perinatal mental illness. Recommendations for changes to the service included an increase in hours of operation to enable greater

HIV incidence is an important measure for monitoring the development of the epidemic, but it is difficult to ascertain. We combined serial HIV prevalence and mortality data to estimate HIV incidence among key affected populations (KAPs) in China. Serial cross-sectional surveys were conducted among KAPs from 2010 to 2014. Trends in HIV prevalence were assessed by the Cochran-Armitage test, adjusted by risk group. HIV incidence was estimated from a mathematical model that describes the relationship between changes in HIV incidence with HIV prevalence and mortality. The crude HIV prevalence for the survey samples remained stable at 1.1 to 1.2% from 2010 to 2014. Among drug users (DUs), HIV prevalence declined from 4.48 to 3.29% (p<0.0001), and among men who have sex with men (MSM), HIV prevalence increased from 5.73 to 7.75% (p<0.0001). Changes in HIV prevalence among female sex workers (FSWs) and male patients of sexually transmitted disease clinics were more modest but remained statistically significant (all p<0.0001). The MSM population had the highest incidence estimates at 0.74% in 2011, 0.59% in 2012, 0.57% in 2013 and 0.53% in 2014. Estimates of the annual incidence for DUs and FSWs were very low and may not be reliable. Serial cross-sectional prevalence data from representative samples may be another approach to construct approximate estimates of national HIV incidence among key populations. We observed that the MSM population had the highest incidence for HIV among high-risk groups in China, and we suggest that interventions targeting MSM are urgently needed to curb the growing HIV epidemic.

The researchers conducted a cross-sectional survey to determine the relationship between handling heavy items during pregnancy and spontaneous abortion among working women in South Korea. One thousand working women were selected from a database of those eligible for maternity benefits under the National Employment Insurance Plan. Study results showed that handling heavy items during pregnancy was associated with an increased risk of spontaneous abortion after adjusting for general characteristics of the participants and their work environment. A collective effort is needed on the parts of employers, employees, occupational health nurses, and the government to protect working women from lifting heavy items while pregnant.

There is limited evidence on potential health benefits of active travel, independently of leisure-time physical activity (PA), with metabolic syndrome (MetS) in Latin-America. To investigate the relationship between active travel and metabolic syndrome (MetS) and its components in a national representative sample of Chilean adults. Cross-sectional study of 2864 randomly selected adults' participants enrolled in the 2009-2010 Chilean National Health Survey (CNHS). Self-reported PA was obtained with the validated Global PA Questionnaire and classifying participants into insufficiently active (<150min/week) or active (≥150min/week). MetS was diagnosed from the modified Adult Treatment Panel (ATP) III criteria with national-specific abdominal obesity cut points. Multilevel logistic regression analysis was applied to estimate associations of travel PA with MetS and its components at a regional level, adjusted for socio-demographic characteristics and other types of PA. 46.2% of the sample engaged in 150min/week of active travel and the prevalence of MetS was 33.7%. Mets was significantly lower among active travel participants. Active travel was associated with lower odds of MetS (OR 0.72; 95%CI 0.61-0.86), triglycerides (OR 0.77; 95%CI 0.64-0.92) and abdominal obesity (OR 0.82; 95%CI 0.69-0.97) after controlling for socio-demographics and other types of PA. Active travel was negatively associated with MetS, triglycerides and abdominal obesity. Efforts to increase regional active travel should be addressed as a measure to prevent and reduce the prevalence of MetS and disease burden in middle income countries. Copyright © 2017 Elsevier Inc.

Objectives To assess attitudes of ICU staff members toward practice guidelines in general and toward a specific guideline, CDC's Guideline for Hand Hygiene in Healthcare Settings; to correlate these attitudes with staff and hospital characteristics; and to examine the impact of staff attitudes toward the Hand Hygiene Guideline on self reported implementation of the Guideline. Methods A cross-sectional survey of staff in 70 ICUs in 39 U.S. hospitals, members of The National Nosocomial Infection Surveillance (NNIS) System. A survey, “Attitudes Regarding Practice Guidelines”, was administered anonymously to all willing staff during a site visit at each hospital; 1,359 ICU personnel: 1,003 nurses (74%), 228 physicians (17%), and 128 others (10%) responded. Results Significantly more positive attitudes toward practice guidelines were found among staff in pediatric as compared with adult ICUs (p<0.001). Nurses and other staff when compared with physicians had more positive attitudes toward guidelines in general but not toward the specific Hand Hygiene Guideline. Those with more positive attitudes were significantly more likely to report that they had implemented recommendations of the Guideline (p<0.001) and used an alcohol product for hand hygiene (p=0.002). Conclusions The majority of staff members were familiar with the CDC Hand Hygiene Guideline. Staff attitudes toward practice guidelines varied by type of ICU and by profession, and more positive attitudes were associated with significantly better self-reported guideline implementation. Because differences in staff attitudes might hinder or facilitate their acceptance and adoption of evidence-based practice guidelines, these results may have important implications for the education and/or socialization of ICU staff.

Patient safety is a core principle of health professional practice and as such requires significant attention within undergraduate curricula. However, patient safety practice is complex requiring a broad range of skills and behaviours including the application of sound clinical knowledge within a range of health care contexts and cultures. There is very little research that explores how this is taught within Australian nursing curricula. To examine how Australian nursing curricula address patient safety; identify where and how patient safety learning occurs; and describe who is responsible for facilitating this learning. A cross-sectional study. Eighteen universities across seven Australian States and Territories. The sample consisted of 18 nursing course coordinators or those responsible for the inclusion of patient safety content within a Bachelor of Nursing course at Australian universities. An online survey was conducted to evaluate the patient safety content included and teaching methods used in Australian pre-registration nursing curricula. Approaches to teaching patient safety vary considerably between universities where patient safety tended to be integrated within undergraduate nursing course subjects rather than explicitly taught in separate, stand-alone subjects. Three-quarters of the surveyed staff believed patient safety was currently being adequately covered in their undergraduate nursing curricula. Although there is consensus in relation to the importance of patient safety across universities, and similarity in views about what knowledge, skills and attitudes should be taught, there were differences in: the amount of time allocated, who was responsible for the teaching and learning, and in which setting the learning occurred and was assessed. There was little indication of the existence of a systematic approach to learning patient safety, with most participants reporting emphasis on learning applied to infection control and medication safety

We examined the distribution of diabetes and modifiable risk factors to provide data to aid diabetes prevention programmes in India. Population-based cross-sectional survey of men and women included in India's third National Family Health Survey (NFHS-3, 2005-2006). The sample is a multistage cluster sample with an overall response rate of 98 %. All states of India are represented in the sample (except the small Union Territories), covering more than 99 % of the country's population. Women (n 99 574) and men (n 56 742) aged 20-49 years residing in the sample households. Prevalence of diabetes was 1598/100 000 (95 % CI 1462, 1735) among men and 1054/100 000 (95 % CI 974, 1134) among women in India. Rural-urban and marked geographic variation were found with higher rates in south and north-eastern India. Weekly and daily fish intake contributed to a significantly higher risk of diabetes among both women and men. Risks of diabetes increased with increased BMI, age and wealth status of both women and men, but no effects of the consumption of milk/curd, vegetables, eggs, television watching, alcohol consumption or smoking were found. Daily consumption of pulse/beans or fruits was associated with a significantly reduced risk of diabetes among women, whereas non-significant inverse associations were observed in the case of men. Prevalence was underestimated using self-reports. The wide variation in self-reported diabetes is unlikely to be due entirely to reporting biases or access to health care, and indicates that modifiable risk factors exist. Prevention of diabetes should focus on obesity and target specific socio-economic groups in India.

The Detector for Advanced Neutron Capture Experiments (DANCE) at Los Alamos National Laboratory (LANL) was used for neutron capture cross section measurement on ^243Am. The high granularity of DANCE (160 BaF2 detectors in a 4π geometry) enables the efficient detection of prompt gamma-rays following neutron capture. DANCE is located on the 20.26 m neutron flight path 14 (FP14) at the Manuel Lujan Jr. Neutron Scattering Center at the Los Alamos Neutron Science Center (LANSCE). The methods and techniques established in [1] were used for the determination of the ^243Am neutron capture cross section. The cross sections were obtained in the range of neutron energies from 0.02 eV to 400 keV. The resonance region was analyzed using SAMMY7 and resonance parameters were extracted. The results will be compared to existing evaluations and calculations. Work was performed under the auspices of the U.S. Department of Energy at Los Alamos National Laboratory by the Los Alamos National Security, LLC under Contract No. DE-AC52-06NA25396 and at Lawrence Livermore National Laboratory by the Lawrence Livermore National Security, LLC under Contract No. DE-AC52-07NA27344.

To estimate the potential to reduce childhood obesity through targeted interventions of overweight households. Cross-sectional nationally representative samples of the Scottish population. Households in Scotland during 2008 and 2009. A total of 1651 households with parents and children aged 2-15 years. The WHO cut-off points for adult body mass index (BMI): overweight (25 to <30 kg/m2) and obese (≥30 kg/m2). Overweight and obesity in childhood respectively defined as a BMI 85th to <95th percentile and ≥95th percentile based on 1990 reference centiles. Thirty-two percent (600/1849) of children and 75% (966/1290) of adults were overweight or obese. Seventy-five percent (1606/2128) of all children lived with a parent who was overweight or obese. Among obese children, 58% (185/318) lived with an obese parent. The population attributable risk percentage of child obesity associated with parental obesity was 32.5%. Targeting obese households would require substantial falls in adult weight and need to reach 38% of all children; it might achieve a reduction in the prevalence of childhood obesity of 14% in these households (from 26% to 12%). Targeting parents with BMI ≥ 40 might reduce the overall prevalence of child obesity by 9%. Such an intervention would require large weight loss, consistent with approaches used for morbidly obese adults; it would involve 4% of all children and lead to a reduction in the prevalence of obesity in these households from 57% to 16%. Family-based interventions for obesity would be most efficiently targeted at obese children whose parents are morbidly obese.

Despite a growing number of studies on leaving the organization or long-term care among professional caregivers for older people, little is known about the impact of types of employment on leaving. To examine the association between the type of employment and intent to leave among Japanese professional caregivers. Secondary analysis of data from the 2006 Working Conditions Survey in Long-term Care, a nationally representative cross-sectional survey done in Japan. 10,107 professional caregivers aged 18 years and older. Predictor of intent to leave was type of employment (full-time permanent, full-time precarious, and part-time precarious). Precarious work was defined as employment that failed to meet the standard of full-time permanent employment, including fixed-term, temporary agency, and part-time work. Covariates included demographics, home or facility care, tenure in the profession, national qualification for caregivers, having other jobs, overtime work, and night shift work. We used multinomial logit models to estimate the strength of the association between the type of employment and intent to leave and to explore the possible mechanisms explaining this association. In the unadjusted model, when compared to part-time precarious workers, full-time permanent workers (OR=2.37; 95% CI=2.06, 2.72) and full-time precarious workers (OR=2.41; 95% CI=2.01, 2.88) were more likely to report intent to leave. After adjustment for covariates, these odds ratios were attenuated, but nevertheless remained significant. Overtime work greatly attenuated these odds ratios in both full-time precarious and full-time permanent workers, and having national qualification for caregivers only did in the case of full-time permanent workers. In contrast to people in other professions, full-time caregivers are more likely to have intent to leave than part-time caregivers. This study highlights the importance of policy strategies for retaining full-time workers by reducing their overtime

Women are increasingly entering the dental work force. This study examines the impact of sex, age and other demographic characteristics on dentists' work force participation and on hours worked from 1979 through 1999. The study drew on cross-sectional data on dentists (4,209 men and 354 women) from national population surveys conducted by the U.S. Bureau of Labor Statistics from 1979 through 1999. The authors used descriptive statistics and regression analyses to examine sex differences in work force participation and in hours worked across age, as well as other factors. Work force participation was high for both men and women. Men worked more hours and worked part time less frequently; they worked more than 42 hours per week more frequently. Older dentists worked fewer hours, with a larger impact of age seen among men. Having children had a significantly greater effect on the number of hours worked per week among female dentists than among male dentists. There were significant differences in dentists' hours worked by sex and by age. The consistency of the results with past studies suggests these differences will hold in the near future. Women's entry into the dental work force has been significant and has helped maintain the supply of dentists. Sex differences in the work force should be considered in evaluating the supply of dentists and related work force policy.

Introduction HIV incidence is an important measure for monitoring the development of the epidemic, but it is difficult to ascertain. We combined serial HIV prevalence and mortality data to estimate HIV incidence among key affected populations (KAPs) in China. Methods Serial cross-sectional surveys were conducted among KAPs from 2010 to 2014. Trends in HIV prevalence were assessed by the Cochran-Armitage test, adjusted by risk group. HIV incidence was estimated from a mathematical model that describes the relationship between changes in HIV incidence with HIV prevalence and mortality. Results The crude HIV prevalence for the survey samples remained stable at 1.1 to 1.2% from 2010 to 2014. Among drug users (DUs), HIV prevalence declined from 4.48 to 3.29% (p<0.0001), and among men who have sex with men (MSM), HIV prevalence increased from 5.73 to 7.75% (p<0.0001). Changes in HIV prevalence among female sex workers (FSWs) and male patients of sexually transmitted disease clinics were more modest but remained statistically significant (all p<0.0001). The MSM population had the highest incidence estimates at 0.74% in 2011, 0.59% in 2012, 0.57% in 2013 and 0.53% in 2014. Estimates of the annual incidence for DUs and FSWs were very low and may not be reliable. Conclusions Serial cross-sectional prevalence data from representative samples may be another approach to construct approximate estimates of national HIV incidence among key populations. We observed that the MSM population had the highest incidence for HIV among high-risk groups in China, and we suggest that interventions targeting MSM are urgently needed to curb the growing HIV epidemic.

Objectives To investigate the major stressors affecting GP registrars, how those at risk can be best identified and the most useful methods of managing or reducing their stress. Design, setting and participants Cross-sectional postal questionnaire of all GP registrars in one large regional training provider's catchment area. Main outcome measures The Depression, Anxiety and Stress Scale (DASS), a specifically developed Registrar Stressor Scale consisting of five subscales of potential stressors, plus closed questions on how to identify and manage stress in GP registrars. Results Survey response rate of 51% (102/199). Rural difficulties followed by achieving a work/life balance were the principal stressors. Ten percent of registrars were mildly or moderately depressed or anxious (DASS) and 7% mild to moderately anxious (DASS). Registrars preferred informal means of identifying those under stress (a buddy system and talks with their supervisors); similarly, they preferred to manage stress by discussions with family and friends, debriefing with peers and colleagues, or undertaking sport and leisure activities. Conclusions This study supports research which confirms that poor psychological well-being is an important issue for a significant minority of GP trainees. Regional training providers should ensure that they facilitate formal and informal strategies to identify those at risk and assist them to cope with their stress. PMID:20181138

Despite progress in recent years, Afghanistan is lagging behind in realizing the full potential of immunization. The country is still endemic for polio transmission and measles outbreaks continue to occur. In spite of significant reductions over the past decade, the mortality rate of children under 5 years of age continues to remain high at 91 per 1000 live births. The study was a descriptive community-based cross sectional household survey. The survey aimed to estimate the levels of immunization coverage at national and province levels. Specific objectives are to: establish valid baseline information to monitor progress of the immunization program; identify reasons why children are not immunized; and make recommendations to enhance access and quality of immunization services in Afghanistan. The survey was carried out in all 34 provinces of the country, with a sample of 6125 mothers of children aged 12-23 months. Nationally, 51% of children participating in the survey received all doses of each antigen irrespective of the recommended date of immunization or recommended interval between doses. About 31% of children were found to be partially vaccinated. Reasons for partial vaccination included: place to vaccinate child too far (23%), not aware of the need of vaccination (17%), no faith in vaccination (16%), mother was too busy (15%), and fear of side effects (11%). The innovative mechanism of contracting out delivery of primary health care services in Afghanistan, including immunization, to non-governmental organizations is showing some positive results in quickly increasing coverage of essential interventions, including routine immunization. Much ground still needs to be covered with proper planning and management of resources in order to improve the immunization coverage in Afghanistan and increase survival and health status of its children.

Objective 1) To determine the non-physician health profession perceived as best qualified to provide weight management; 2) To examine nutrition professionals’ current practice characteristics and perceived challenges and solutions for obesity care; and 3) To examine the association between nutrition professionals’ quality of training and self-efficacy in weight management. Design and methods We analyzed a 2014 national cross-sectional online survey of 500 U.S. non-physician health professionals (100 from each: nutrition, nursing, behavioral/mental health, exercise, pharmacy). Results Nutrition professionals most commonly self-identified as the most qualified group to help patients lose weight (92%), sentiments supported by other health professionals (57%). The most often cited challenge was lack of patient adherence (87%). Among nutrition professionals, 77% reported receiving high quality training in weight loss counseling. Nutrition professionals who reported high quality training were significantly more likely to report confidence (95% vs. 48%) and success (74% vs. 50%) in helping obese patients lose weight (p<0.05) than those reporting lower quality training. Conclusion Across all non-physician health professionals, nutrition professionals were identified as best suited to provide routine weight management counseling to obese patients. Yet, nutrition professionals’ receipt of high quality weight management training appears critical to their success in helping patients lose weight. PMID:25445319

In the US, once a medical device is made available for use, several requirements have been established by the US Food and Drug Administration (FDA) to ensure ongoing post-market surveillance of device safety and effectiveness. Our objective was to determine how commonly medical device manufacturers initiate post-market clinical studies or augment FDA post-market surveillance requirements for higher-risk devices that are most often approved via the FDA's pre-market approval (PMA) pathway. We conducted a cross-sectional survey of 47 manufacturers with operations in California, Minnesota, and Massachusetts who market devices approved via the PMA pathway. Among 22 respondents (response rate =47%), nearly all self-reported conducting post-market clinical research studies, commonly between 1 and 5; only 1 respondent reported never conducting post-market clinical research studies. While manufacturers most often engaged in these studies to satisfy FDA requirements, other reasons were reported, including performance monitoring and surveillance and market acceptance initiatives. Risks of conducting and not conducting post-market clinical research studies were described through open-ended response to questions. Medical device manufacturers commonly initiate post-market clinical studies at the request of the FDA. Clinical data from these studies should be integrated into national post-market surveillance initiatives.

This protocol builds on the development of a) a framework that identified the various supports (i.e. positions, activities, interventions) that a healthcare organisation or health system can implement for evidence-informed decision-making (EIDM) and b) a qualitative study that showed the current mix of supports that some Canadian healthcare organisations have in place and the ones that are perceived to facilitate the use of research evidence in decision-making. Based on these findings, we developed a web survey to collect cross-sectional data about the specific supports that regional health authorities and hospitals in two Canadian provinces (Ontario and Quebec) have in place to facilitate EIDM. This paper describes the methods for a cross-sectional web survey among 32 regional health authorities and 253 hospitals in the provinces of Quebec and Ontario (Canada) to collect data on the current mix of organisational supports that these organisations have in place to facilitate evidence-informed decision-making. The data will be obtained through a two-step survey design: a 10-min survey among CEOs to identify key units and individuals in regard to our objectives (step 1) and a 20-min survey among managers of the key units identified in step 1 to collect information about the activities performed by their unit regarding the acquisition, assessment, adaptation and/or dissemination of research evidence in decision-making (step 2). The study will target three types of informants: CEOs, library/documentation centre managers and all other key managers whose unit is involved in the acquisition, assessment, adaptation/packaging and/or dissemination of research evidence in decision-making. We developed an innovative data collection system to increase the likelihood that only the best-informed respondent available answers each survey question. The reporting of the results will be done using descriptive statistics of supports by organisation type and by province. This study will

Internationally the recruitment and retention of Indigenous and minority peoples into nursing is a persistent challenge, despite their participation being essential in reducing health disparities and improving health service quality for Indigenous and minority users. We aimed to identify Māori (Indigenous to New Zealand) nursing students' experiences of undertaking a nursing degree program. A non-experimental cross-sectional survey was undertaken with undergraduate nursing students identifying as Māori. The surveys were analyzed using descriptive and inferential statistics. One hundred and eight students responded, with a career, stable income, and desire to make a difference in Māori health outcomes motivating most to embark on a nursing program. They reported numerous obstacles that compromised their academic advancement. However, affirming students' identities; providing academic support; accessing Indigenous role models, mentors and relevant clinical experiences; and, having supportive teaching and learning environments and the inclusion of Indigenous content in curricula; were identified as strategies that promoted retention in nursing programs.

To explore general practitioner's (GP) knowledge, attitudes and practice regarding female genital cosmetic surgery (FGCS) in Australia. Cross-sectional survey. Australia. GPs who attended a women's health seminar and GPs who subscribed to a non-governmental, national health professional organisation database that provides education to primary care professionals. A national online survey of GPs was conducted for the 10-week period, starting 1 week prior and 2 months after a Women's Health seminar was held in Perth on 8 August 2015. 31 questions prompted GPs' knowledge, attitudes and practice in managing patients asking about FGCS. The survey was fully completed by 443 GPs; 54% had seen patients requesting FGCS. Overall, 75% (95% CI 71% to 79%) of GPs rated their knowledge of FGCS as inadequate and 97% (95% CI 94% to 99%) had been asked by women of all ages about genital normality. Of those who had seen patients requesting FGCS, nearly half (44%, 95% CI 38% to 51%) reported they had insufficient knowledge of risks of FGCS procedures and 35% (95% CI 29% to 41%) reported seeing females younger than 18 years of age requesting FGCS. Just over half (56%, 95% CI 51% to 60%) of the GPs felt that women should be counselled before making a referral for FGCS. More than half the GPs suspected psychological disturbances in their patients requesting FGCS such as depression, anxiety, relationship difficulties and body dysmorphic disorder. GPs see women of all ages presenting with genital anatomy concerns and in those who request FGCS, GPs often suspected a range of mental health difficulties. GPs require greater education to support their patients who request FGCS. Published by the BMJ Publishing Group Limited.

To use a nationwide household survey tool to provide an estimate of injury prevalence, mechanisms of traumatic injuries, and number of injury-related deaths in a low-income country. A randomized, cross-sectional nationwide survey using the Surgeons OverSeas Assessment of Surgical Need tool was conducted in 2012. Sierra Leone, Africa. Three thousand seven hundred fifty randomly selected participants throughout Sierra Leone. Mechanisms of injury based on age, sex, anatomic location, cause, and sociodemographic factors as well as mechanisms of injury-related deaths in the previous year were the primary outcome measures. Data were collected and analyzed from 1843 households and 3645 respondents (98% response rate). Four hundred fifty-two respondents (12%) reported at least 1 traumatic injury in the preceding year. Falls were the most common cause of nonfatal injuries (40%). The extremities were the most common injury site regardless of age or sex. Traffic injuries were the leading cause of injury-related deaths (32% of fatal injuries). This study provides baseline data on the mechanisms of traumatic injuries as well as the sociodemographic factors affecting injury prevalence in one of the world's poorest nations. It is anticipated that these data will provide an impetus for further studies to determine injury severity, associated disability, and barriers to accessing care in these resource-poor areas.

Objectives To determine the prevalence of workplace violence that Chinese nurses have encountered, identify risk factors and provide a basis for future targeted interventions. Setting Heilongjiang, a province in northeast China. Methods A cross-sectional survey. Participants A total of 588 nurses provided data. There were also in-depth interviews with 12 nurses, 7 hospital administrators and 6 health officials. Results A total of 7.8% of the nurses reported physically violent experiences and 71.9% reported non-physically violent experiences in the preceding year. Perpetrators were patients or their relatives (93.5% and 82%, respectively), and 24% of nurses experienced non-physical violence that involved Yi Nao (gangs specifically targeting hospitals). Inexperienced nurses were more likely to report physical (13.2%) or non-physical (89.5%) violence compared with experienced nurses. Graduate-level nurses were more likely to perceive and report non-physical violence (84.6%). Nurses who worked rotating shifts were 3.668 times (95% CI 1.275 to 10.554) more likely to experience physical violence, and 1.771 times (95% CI 1.123 to 2.792) more likely to experience non-physical violence compared with nurses who worked fixed day shifts. Higher anxiety levels about workplace violence and work types were associated with violence. Interviewees perceived financial burdens, unsatisfactory treatment outcomes and miscommunications as influencing factors for workplace violence. Conclusions Preplacement education should focus on high-risk groups to reduce workplace violence. Increased awareness from the public and policymakers is necessary to develop effective control strategies at individual, hospital and national levels. PMID:25814496

Background Pulmonary rehabilitation (PR) is a comprehensive intervention of exercise training, education, and behaviour change to improve the physical and psychological condition of people with chronic respiratory disorders, such as chronic obstructive pulmonary disease (COPD) and to promote long-term adherence to health-enhancing behaviours. Although PR is considered the standard of care for patients with COPD who remain symptomatic despite bronchodilator therapies, current evidence suggests that only 1.15% of COPD patients across Canada have access to PR facilities for care. Objectives The objectives of this study were to identify the number of health care facilities across Ontario providing PR services for patients with COPD, describe the scope of those services, and determine the province's current capacity to provide PR services relative to need, for the province as a whole and by local health integration network (LHIN). Methods The Pulmonary Rehabilitation Programs in Ontario (PRO) Survey was a province-wide, descriptive, cross-sectional survey of health care facilities (hospitals, family health teams, and community health centres). It was distributed to 409 facilities to collect information on various aspects of PR services in the province. Results Between April 2013 and February 2014, 187 facilities responded to the survey (46% response rate). Most responding centres (144) did not offer PR services, and only 43 were full PR sites providing a comprehensive program. Hospital-based programs made up the majority of sites offering full PR services (67%), followed by programs based at family health teams (19%) and community health centres (14%). More than 90% of PR programs are outpatient-based. The average wait time for outpatient PR was 6.9 weeks, and 58% of programs provide services 5 days per week. More than 80% of patients attending PR complete the full program. Across all program types, the total estimated provincial capacity for PR outpatient care is 4

Job satisfaction has become a critical issue for healthcare organizations, particularly in nursing, because of the shortage of nursing labor, the effect on patient care, and the associated costs. This study explores the factors that influence the level of job satisfaction of nurses working in one regional hospital in Oman. This study aims to measure the job satisfaction of nurses working at a regional hospital in Oman and to determine the factors that most significantly influence this satisfaction. Job satisfaction is measured using the McCloskey/Mueller Satisfaction Scale. In addition, the demographic characteristics of participants (age, gender, level of education, years of experience, marital status, work shift, work unit, and nationality) are obtained to assess potential correlations. A questionnaire survey was used to collect the data, and stratified random sampling was used to recruit potential participants. A cross-sectional survey was used to collect data from 155 participants who worked at one regional hospital in Oman, with survey data analyzed using SPSS version 19. One hundred forty-three valid responses were received (response rate: 92%). The study used descriptive data analysis to address the first research question and used analysis methods such as multiregression analyses, and one-way analysis of variance to identify the relationships between the other variables. The overall mean score for satisfaction was 3.49, indicating that participants had a moderate level of job satisfaction. "Interaction with coworkers" and "extrinsic reward" earned, respectively, the highest and lowest job satisfaction ratings on the subscale of McCloskey/Mueller Satisfaction Scale. The results showed that age, work shift, and nationality each had a statistically significant effect on overall job satisfaction. A multiple regression analysis indicated that 21.8% of the total variance in the dependent variables was explained by being non-Omani in nationality, indicating that

To examine the distribution of plasma glucose and related cardiovascular risk factors in two occupation-based cross-sectional surveys in a Chinese ethnic population. Two cross-sectional surveys in a Hong Kong working population. In 1990, 1496 participants aged 18-66 years underwent an OGTT, anthropometric, and other biochemical measures. Identical measures were collected from 534 participants aged 20-72 years in 2001-2003. Data were direct age-standardised to compare CVD risk factor prevalence. Linear regression modelling was used to examine the distribution of continuous CVD risk factors. Mean (SD) 2-h plasma glucose values were 5.6mmol/l (2.1) in 1990 and 6.5mmol/l (2.5) in 2001-2003, an apparent increase of 0.5mmol/l (95% CI 0.3 to 0.7, p<0.001) after age and sex adjustment. However, there was no significant difference in the age-standardised prevalence of glucose intolerance, overweight or obesity. There were significantly smaller proportions of women with hypertension and hyperlipidaemia and male smokers in the second compared to the first survey. We observed a relatively adverse glycaemia profile, which may have worsened over time, in two healthy populations of survey respondents, with comparatively low rates of most CVD risk factors. This has implications for the future burden of disease associated with hyperglycaemia in this population. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

A mathematical technique developed to design entrance sections for transonic or high-speed subsonic wind tunnels with rectangular cross sections is discribed. The transition from a circular cross-section setting chamber to a rectangular test section is accomplished smoothly so as not to introduce secondary flows (vortices or boundary-layer separation) into a uniform test stream. The results of static-pressure measurements in the transition region and of static and total-pressure surveys in the test section of a pilot model for a new facility at the Ames Research Center are presented.

Self-Care in Palliative Care Nursing and Medical Professionals: A Cross-Sectional Survey.

Self-care is an important consideration for palliative care professionals. To date, few details have been recorded about the nature or uptake of self-care practices in the palliative care workforce. As part of a broader mixed methods study, this article reports findings from a national survey of nurses and doctors. The objective of this study was to examine perceptions, education, and practices relating to self-care among palliative care nursing and medical professionals. A cross-sectional survey using REDCap software was conducted between April and May 2015. Perceived importance of self-care, self-care education and planning, and self-care strategies most utilized were explored. Descriptive statistics were calculated and content analysis used to identify domains of self-care. Three hundred seventy-two palliative care nursing and medical professionals practicing in Australia. Most respondents regarded self-care as very important (86%). Some rarely practised self-care and less than half (39%) had received training in self-care. Physical self-care strategies were most commonly reported, followed closely by social self-care and inner self-care. Self-care plans had been used by a small proportion of respondents (6%) and over two-thirds (70%) would consider using self-care plans if training could be provided. Self-care is practised across multiple health related domains, with physical self-care strategies used most frequently. Australian palliative care nurses and doctors recognize the importance of self-care practice, but further education and training are needed to increase their understanding of, and consistency in, using effective self-care strategies. These findings carry implications for professional practice and future research.

Spiritual health, along with physical, emotional, and social aspects, is one of four domains of health. Assessment in this field of research is challenging methodologically. No contemporary population-based studies have profiled the spiritual health of adolescent Canadians with a focus on health inequalities. In a 2014 nationally representative sample of Canadians aged 11-15 years we therefore: (1) psychometrically evaluated a series of items used to assess the perceived importance of spiritual health and its four potential sub-domains (connections with: self, others, nature and the natural environment, and the transcendent) to adolescents; (2) described potential inequalities in spiritual health within adolescent populations, overall and by spiritual health sub-domain, by key socio-demographic factors. Cross-sectional analysis of survey reports from the 2014 (Cycle 7) of the Canadian Health Behaviour in School-aged Children study (weighted n = 25,036). Principal components analysis followed by confirmatory factor analysis were used to explore the psychometric properties of the spiritual health items and the associated composite scale describing perceived importance of spiritual health. Associations among this composite scale, its individual sub-domains, and key socio-demographic factors were then explored. The principal components analysis best supported a four-factor structure where the eight scale items loaded highly according to the original four domains. This was also supported in confirmatory factor analyses. We then combined the eight items into composite spiritual health score as supported by theory, principal components analysis findings, and acceptable tests of reliability. Further confirmatory factor analysis suggested the need for additional refinements to this scale.

Interactions of species, such as atoms, radicals, molecules, electrons, and photons, in plasmas used for materials processing could be very complex, and many of them could be described in terms of collisional cross-sections. Researchers involved in plasma simulations must select reasonable cross-sections for collisional processes for implementing them into their simulation codes to be able to correctly simulate plasmas. However, collisional cross-section data are difficult to obtain, and, for some collisional processes, the cross-sections are still not known. Data on collisional cross-sections can be obtained from numerous sources including numerical calculations, experiments, journal articles, conference proceedings, scientific reports, various universities' websites, national labs and centers specifically devoted to collecting data on cross-sections. The cross-sections data received from different sources could be partial, corresponding to limited energy ranges, or could even not be in agreement. The DBCC software package was designed to help researchers in collecting, comparing, and selecting cross-sections, some of which could be constructed from others or chosen as defaults. This is important as different researchers may place trust in different cross-sections or in different sources. We will discuss the details of DBCC and demonstrate how it works and why it is beneficial to researchers working on plasma simulations.

The goal of this research is to study the psychosocial determinants of HIV-testing as a function of the decision or change stage concerning this health behavior. The determinants considered in the major ongoing health models and the stages contemplated in the Precaution Adoption Process Model are analysed. A cross-sectional survey was administered to 1,554 people over 16 years of age living in Spain by a computer-assisted telephone interview (CATI). The sample design was randomised, with quotas of sex and age. The survey measured various psychosocial determinants of health behaviors considered in the main cognitive theories, the interviewees' stage of change concerning HIV-testing (lack of awareness, decision not to act, decision to act, action, maintenance, and abandonment), and the signal for the action of getting tested or the perceived barriers to being tested. Approximately two thirds of the population had not ever had the HIV test. The predominant stage was lack of awareness. The most frequently perceived barriers to testing were related to the health system and to the stigma. We also found that the psychosocial determinants studied differed depending on the respondents' stage of change. Perception of risk, perceived self-efficacy, proximity to people who had been tested, perceived benefits of knowing the diagnosis, and a positive instrumental and emotional attitude were positively associated with the decision and maintenance of testing behavior. However, unrealistic underestimation of the risk of HIV infection, stereotypes about the infection, and the perceived severity of HIV were associated with the decision not to be tested. There are various sociocognitive and motivational profiles depending on people's decision stage concerning HIV-testing. Knowing this profile may allow us to design interventions to influence the psychosocial determinants that characterise each stage of change.

Some medical doctors in India have publicly expressed opposition to making emergency contraceptive pills (ECPs) easily accessible, even though ECPs are included in the method mix of the Ministry of Health and Family Welfare program and as an over-the-counter (OTC) product. Such opposition affects access to ECPs by influencing policy, procurement, and distribution, besides stigmatizing the ECP user. This study was conducted to assess ECP knowledge, attitudes, and practices of doctors in North India. A cross-sectional survey of 83 doctors who provide ECPs, randomly selected from 3 cities in the state of Uttar Pradesh, was conducted in 2011. The quantitative data were complemented by 19 in-depth interviews with purposively selected senior gynecologists and other opinion leaders. All surveyed physicians cited the correct dose and regimen for ECPs. However, the large majority of those surveyed believed that ECPs work by preventing implantation. (The best evidence currently indicates that ECPs do not work by preventing implantation.) Most doctors also believed incorrectly that ECPs have several contraindications and side effects. They also had strong reservations against OTC provision of ECPs by pharmacists and community health workers (CHWs) and negative attitudes toward ECP users, which serve as serious medical barriers to mainstreaming use of ECPs. Physicians and their professional associations exert a strong influence on the operationalization of national contraceptive policies. Evidence-based advocacy and educational campaigns targeting doctors are needed to address and resolve their reservations about ECPs, particularly about its provision as an OTC product and its distribution by CHWs. Partnerships with medical associations can help reduce doctors' negative attitudes and create a conducive environment for influencing clinical practices. Such changes are needed to increase the availability and use of ECPs as part of a package of a full range of contraceptive method

Research evaluating the relation of workplace psychosocial factors to mental health among U.S. women of different racial/ethnic backgrounds is limited. This study investigated the relationship between work-related psychosocial factors and mental health among non-Hispanic Black, Hispanic, and non-Hispanic White women using data from the 2010 National Health Interview Survey. Independent variables of interest included job insecurity, workplace harassment, and work-family conflict (WFC). Multiple Poisson regression models were used to examine the associations between the outcome and independent variables. The prevalence of unfavorable mental health was highest among non-Hispanic Black women (36%) compared to Hispanic (34%) and non-Hispanic White (30%) women. A higher proportion of non-Hispanic Black women reported WFC compared to Hispanics and non-Hispanic Whites (χ 2 = 15.50, p < .01), while more Hispanics reported job insecurity (χ 2 = 116.81, p < .01). Prevalence of workplace harassment did not differ significantly by race/ethnicity. Odds of unfavorable mental health were significantly higher for women reporting psychosocial work factors. Unexpectedly, a greater association between psychosocial work factors and unfavorable mental health was observed among non-Hispanic White women compared to non-White women; however, caution should be taken in interpreting these cross-sectional results. Future studies should investigate temporal associations and additional psychosocial variables that were not available for use in the current study.

The purpose of this study was to describe how people use social media to find and disseminate information about evidence-based maternity care. We used a cross-sectional Internet-based survey design in which 1,661 participants were recruited from childbirth-related blogs. Participants answered questions about how they find, use, and share evidence-based maternity information using social media. Overall, women in this study were highly engaged in using social media to find and share maternity information. Most respondents were very interested in reading evidence-based maternity care articles online. Most intend to use this information that they found, despite the fact that a substantial percentage had no intentions of discussing this information with their childbirth educators or physician.

Online social networks (OSNs) enable health professionals to learn informally, for example by sharing medical knowledge, or discussing practice management challenges and clinical issues. Understanding how learning occurs in OSNs is necessary to better support this type of learning. Through a cross-sectional survey, this study found that learning interaction in OSNs is low in general, with a small number of active users. Some health professionals actively used OSNs to support their practice, including sharing practical and experiential knowledge, benchmarking themselves, and to keep up-to-date on policy, advanced information and news in the field. These health professionals had an overall positive learning experience in OSNs.

Airline carriers have equipment, procedures, and protocols in place to handle in-flight medical events (IFMEs). Community physicians may be asked for aid during IFMEs. Cross-Sectional Survey of Physicians on Providing Volunteer Care for In-Flight Medical Events surveyed self-assessed awareness and knowledge, perceived barriers, and suggestions for improving responses to IFMEs. We composed a survey regarding clinicians' self-assessed understanding of in-flight resources, procedures, flight environmental issues, and Good Samaritan protections. The survey was distributed primarily via electronic mail to medical staff list serves to a total of approximately 1300 physicians representing 2 health networks that serve urban, suburban, and rural areas in both inpatient and outpatient settings. Total number of responses was 418. Physician response rate was 29.2% (379/1300). In 3% (39/1300), the responder either failed to indicate their background or was another type of health care professional (e.g., dentist, medical student, physician assistant). Of the physicians, 37.5% (142/379) were primary care and 42% (177/418) of responders reported at least one experience of being asked to volunteer. When asked how well they understand the protocols with which medical events are handled, 64% (262/412) responded "not at all" and 23% (94/412) reported "a little" knowledge. Only 56% (223/397) answered that 75% or more of U.S. flights have ground medical support available. There were 73% (298/411) who believed airlines were required to have medical supplies, but 54% (222/410) reported no knowledge of supplies available. A total of 69% (279/403) believed or were sure that the U.S. has a Good Samaritan law that applies to IFMEs. Many physicians lack basic knowledge about IFMEs. Responders may assist more effectively if better informed about protocols and the availability of ground medical support. Education and timely information support are recommended.Chatfield E, Bond WF, McCay B

Cross-sectional study design is a type of observational study design. In a cross-sectional study, the investigator measures the outcome and the exposures in the study participants at the same time. Unlike in case-control studies (participants selected based on the outcome status) or cohort studies (participants selected based on the exposure status), the participants in a cross-sectional study are just selected based on the inclusion and exclusion criteria set for the study. Once the participants have been selected for the study, the investigator follows the study to assess the exposure and the outcomes. Cross-sectional designs are used for population-based surveys and to assess the prevalence of diseases in clinic-based samples. These studies can usually be conducted relatively faster and are inexpensive. They may be conducted either before planning a cohort study or a baseline in a cohort study. These types of designs will give us information about the prevalence of outcomes or exposures; this information will be useful for designing the cohort study. However, since this is a 1-time measurement of exposure and outcome, it is difficult to derive causal relationships from cross-sectional analysis. We can estimate the prevalence of disease in cross-sectional studies. Furthermore, we will also be able to estimate the odds ratios to study the association between exposure and the outcomes in this design.

Since 2013, the National Resident Matching Program (NRMP) has asked all programs to declare themselves to be "all in" or "all out" for the NRMP. Before this rule was enacted, program directors who were surveyed expressed concerns about what they anticipated with the change, including resources for increased applications and potential delays with residency start times. This study investigated the positive and negative effects of the rule change on recruiting seen from the perspective of internal medicine (IM) program directors. In this mixed model cross-sectional survey, Accreditation Council for Graduate Medical Education-accredited IM program directors were surveyed regarding their impressions of the impact of the policy change. Data were aggregated using constant comparative analysis. A total of 127 of 396 (32%) IM program directors responded, and 122 of 127 (96%) identified their program as "all in." A total of 110 respondents expressed impressions of the rule change, with 48% (53 of 111) reporting positive responses, 28% (31 of 111) neutral responses, and 24% (27 of 111) negative responses. Programs with higher percentages of visa-holding residents had lower positive responses (37% [22 of 60] versus 61% [31 of 51]). Resident quality was felt to be unchanged or improved by most program directors (93%, 103 of 111), yet 24% (27 of 112) reported increases in delayed start times for visa-holding residents. Qualitative analysis identified increased fairness, at the expense of an increase in program resources as a result of the change. A slight majority of residency programs reported a neutral or negative impression of the rule change. Since the rule change, program directors noted increased application volume and delayed residency starts for visa-holding residents.

To determine the incidence of - and illnesses commonly associated with - catastrophic household expenditure on health in Nepal. We did a cross-sectional population-based survey in five municipalities of Kathmandu Valley between November 2011 and January 2012. For each household surveyed, out-of-pocket spending on health in the previous 30 days that exceeded 10% of the household's total expenditure over the same period was considered to be catastrophic. We estimated the incidence and intensity of catastrophic health expenditure. We identified the illnesses most commonly associated with such expenditure using a Poisson regression model and assessed the distribution of expenditure by economic quintile of households using the concentration index. Overall, 284 of the 1997 households studied in Kathmandu, i.e. 13.8% after adjustment by sampling weight, reported catastrophic health expenditure in the 30 days before the survey. After adjusting for confounders, this expenditure was found to be associated with injuries, particularly those resulting from road traffic accidents. Catastrophic expenditure by households in the poorest quintile were associated with at least one episode of diabetes, asthma or heart disease. In an urban area of Nepal, catastrophic household expenditure on health was mostly associated with injuries and noncommunicable diseases such as diabetes and asthma. Throughout Nepal, interventions for the control and management of noncommunicable diseases and the prevention of road traffic accidents should be promoted. A phased introduction of health insurance should also reduce the incidence of catastrophic household expenditure.

Most cancer patients experience the time when a doctor must "break the bad news" to them, a time when it is necessary for patients to call upon their self-determination to aid in the battle with cancer. The purpose of our study was to clarify the percentage of times doctors deliver bad news to patients at the end of life in each of four different situations, and to define the most common recipients of this bad news. We compare these results for two timepoints: 2006 and 2012. The study had a national cross-sectional design consisting of self-completed questionnaires sent to all hospitals that provide cancer care. We mailed them to hospital directors in January and February of 2012, requesting a reply. The results of the same survey in 2006 were employed as a point for comparison. A total of 1224 questionnaires were returned during 2012. 1499 responses collected in 2006 were employed as reference data. Some hospital characteristics had changed over that interval; however, the new data obtained were representative for patients being treated in Japanese cancer care hospitals. In hospitals with 300-499, there were significant differences between 2006 and 2012 in the providing information about ("disclosure of cancer diagnosis," "therapeutic options for treatment," and "a life-prolonging treatment"). In addition, the likelihood of doctors delivering bad news to patients and family members (as opposed to family members only) at the end of life increased from 2006 to 2012. Our results suggest that the overall incidence of bad news being disclosed has increased, especially in hub medical institutions for cancer care. Advanced treatment options or domestic legislation may have influenced the frequency or type of bad news.

Management of Patient-Reported Outcome (PRO) Alerts in Clinical Trials: A Cross Sectional Survey.

2016-01-01

Assessment of patient-reported outcomes (PROs) provides valuable information to inform patient-centered care, but may also reveal 'PRO alerts': psychological distress or physical symptoms that may require an immediate response. Ad-hoc management of PRO alerts in clinical trials may result in suboptimal patient care or potentially bias trial results. To gain greater understanding of current practice in PRO alert management we conducted a national survey of personnel involved in clinical trials with a PRO endpoint. We conducted a national cross-sectional survey of 767 UK-based research nurses, data managers/coordinators, trial managers and chief/principal investigators involved in clinical trials using PROs. Respondents were self-selected volunteers from a non-randomised sample of eligible individuals recruited via 55 UK Clinical Research Collaboration Registered Clinical Trials Units and 19 Comprehensive Local Research Networks. Questions centred on the proportion of trial personnel encountering alerts, how staff responded to PRO alerts and whether current guidance was deemed sufficient to support research personnel. We undertook descriptive analyses of the quantitative data and directed thematic analysis of free-text comments. 20% of research nurses did not view completed PRO questionnaires and were not in a position to discover alerts, 39-50% of the remaining respondent group participants reported encountering PRO alerts. Of these, 83% of research nurses and 54% of data managers/trial coordinators reported taking action to assist the trial participant, but less than half were able to record the intervention in the trial documentation. Research personnel reported current PRO alert guidance/training was insufficient. Research personnel are intermittently exposed to PRO alerts. Some intervene to help trial participants, but are not able to record this intervention in the trial documentation, risking co-intervention bias. Other staff do not check PRO information

Awareness of surgical costs: a multicenter cross-sectional survey.

Resource scarcity continues to be an important problem in modern surgical practice. Studies in North America and Europe have found that medical professionals have limited understanding of the costs of medical care. No cost awareness studies have been undertaken in Australasia or specifically focusing on the surgical team. This study determined the cost of a range of commonly used diagnostic tests, procedures, and hospital resources associated with care of the surgical patient. The surgical teams' awareness of these costs was then assessed in a multicenter cross-sectional survey. In total, 14 general surgical consultants, 14 registrars, and 25 house officers working in three New Zealand hospitals were asked to estimate the costs of 14 items commonly associated with patient care. Cost estimations were considered correct if within 25% plus or minus of the actual cost. Accuracy was assessed by calculating the median, mean, and absolute percentage discrepancy. A total of 57 surveys were completed. Of which, four were incomplete and were not included in the analysis. Cost awareness was generally poor, and members of the surgical team were rarely able to estimate the costs to within 25%. The mean absolute percentage error was 0.87 (95% CI: 0.58-1.18) and underestimates were most common. There was no significant difference in estimate accuracy between consultants, registrars, or house officers, or between consultants working in both public/private practice compared with those working in public practice alone. There is poor awareness of surgical costs among consultant surgeons, registrars, and junior physicians working in Australasia. Copyright © 2014 Association of Program Directors in Surgery.

2018-01-01

With the ongoing demographic and epidemiological transition, cancer is emerging as a major public health concern in India. This paper uses nationally representative household survey to examine the overall prevalence and economic burden of cancer in India. The age-standardized prevalence of cancer is estimated to be 97 per 100,000 persons with greater prevalence in urban areas. The evidence suggests that cancer prevalence is highest among the elderly and also among females in the reproductive age groups. Cancer displays a significant socioeconomic gradient even after adjusting for age-sex specifics and clustering in a multilevel regression framework. We find that out of pocket expenditure on cancer treatment is among the highest for any ailment. The average out of pocket spending on inpatient care in private facilities is about three-times that of public facilities. Furthermore, treatment for about 40 percent of cancer hospitalization cases is financed mainly through borrowings, sale of assets and contributions from friends and relatives. Also, over 60 percent of the households who seek care from the private sector incur out of pocket expenditure in excess of 20 percent of their annual per capita household expenditure. Given the catastrophic implications, this study calls for a disease-based approach towards financing such high-cost ailment. It is suggested that universal cancer care insurance should be envisaged and combined with existing accident and life insurance policies for the poorer sections in India. In concluding, we call for policies to improve cancer survivorship through effective prevention and early detection. In particular, greater public health investments in infrastructure, human resources and quality of care deserve priority attention.

This study aimed to determine the number eligible for bariatric surgery and their sociodemographic characteristics. We used Health Survey for England 2006 data, representative of the non-institutionalized English population. The number of people eligible for bariatric surgery in England based on national guidance is unknown. The UK National Institute for Health and Clinical Excellence criteria for eligibility are those with body mass index (BMI) 35-40 kg/m(2) with at least one comorbidity potentially improved by losing weight or a BMI > 40 kg/m(2). Of 13,742 adult respondents (≥18 years), we excluded participants with invalid BMI (n = 2103), comorbidities (n = 2187) or sociodemographic variables (n = 27) data, for a final study sample of 9425 participants. The comorbidities examined were hypertension, type 2 diabetes, stroke, coronary heart disease and osteoarthritis. Sociodemographic variables assessed included age, sex, employment status, highest educational qualification, social class and smoking status. 5.4% (95% CI 5.0-5.9) of the non-institutionalized adult population in England could meet criteria for having bariatric surgery after accounting for survey weights. Those eligible were more likely than the general population to be women (60.1% vs. 39.9%, p<0.01), retired (22.4% vs. 12.8% p<0.01), and have no formal educational qualifications (35.7% vs. 21.3%, p<0.01). The number of adults potentially eligible for bariatric surgery in England (2,147,683 people based on these results and 2006 population estimates) far exceeds previous estimates of eligibility. In view of the sociodemographic characteristics of this group, careful resource allocation is required to ensure equitable access on the basis of need.

Objectives The aim of this study was to analyse the clustering of multiple health-related behaviours among adolescents and describe which socio-demographic characteristics are associated with these patterns. Design Cross-sectional study. Setting Brazilian schools assessed by the National Survey of School Health (PeNSE, 2012). Participants 104 109 Brazilian ninth-grade students from public and private schools (response rate=82.7%). Methods Exploratory and confirmatory factor analyses were performed to identify behaviour clustering and linear regression models were used to identify socio-demographic characteristics associated with each one of these behaviour patterns. Results We identified a good fit model with three behaviour patterns. The first was labelled ‘problem-behaviour’ and included aggressive behaviour, alcohol consumption, smoking, drug use and unsafe sex; the second was labelled ‘health-compromising diet and sedentary behaviours’ and included unhealthy food indicators and sedentary behaviour; and the third was labelled ‘health-promoting diet and physical activity’ and included healthy food indicators and physical activity. No differences in behaviour patterns were found between genders. The problem-behaviour pattern was associated with male gender, older age, more developed region (socially and economically) and public schools (compared with private). The ‘health-compromising diet and sedentary behaviours’ pattern was associated with female gender, older age, mothers with higher education level and more developed region. The ‘health-promoting diet and physical activity’ pattern was associated with male gender and mothers with higher education level. Conclusions Three health-related behaviour patterns were found among Brazilian adolescents. Interventions to decrease those negative patterns should take into account how these behaviours cluster together and the individuals most at risk. PMID:28186927

To determine the frequency and perceptions of herbal medicine use among Hmong Americans. Cross-sectional telephone survey. Sacramento, California Hmong community. Out of 118 subjects reached, 77 (65.3 %) reported lifetime use of herbal medicines. A majority of respondents agreed that herbal medicines were able to treat the body as a whole. Respondents felt that a leaflet of information indicating uses/side effects would be important to include for herbal medicines. Herbal medicine use was commonly reported among Hmong Americans. Thus, health care providers should be encouraged to discuss these alternative medicines with their Hmong American patients.

Objectives Pedometers are an effective self-monitoring tool to increase users' physical activity. However, a range of advanced trackers that measure physical activity 24 hours per day have emerged (eg, Fitbit). The current study aims to determine people's current use, interest and preferences for advanced trackers. Design and participants A cross-sectional national telephone survey was conducted in Australia with 1349 respondents. Outcome measures Regression analyses were used to determine whether tracker interest and use, and use of advanced trackers over pedometers is a function of demographics. Preferences for tracker features and reasons for not wanting to wear a tracker are also presented. Results Over one-third of participants (35%) had used a tracker, and 16% are interested in using one. Multinomial regression (n=1257) revealed that the use of trackers was lower in males (OR=0.48, 95% CI 0.36 to 0.65), non-working participants (OR=0.43, 95% CI 0.30 to 0.61), participants with lower education (OR=0.52, 95% CI 0.38 to 0.72) and inactive participants (OR=0.52, 95% CI 0.39 to 0.70). Interest in using a tracker was higher in younger participants (OR=1.73, 95% CI 1.15 to 2.58). The most frequently used tracker was a pedometer (59%). Logistic regression (n=445) revealed that use of advanced trackers compared with pedometers was higher in males (OR=1.67, 95% CI 1.01 to 2.79) and younger participants (OR=2.96, 95% CI 1.71 to 5.13), and lower in inactive participants (OR=0.35, 95% CI 0.19 to 0.63). Over half of current or interested tracker users (53%) prefer to wear it on their wrist, 31% considered counting steps the most important function and 30% regarded accuracy as the most important characteristic. The main reasons for not wanting to use a tracker were, ‘I don't think it would help me’ (39%), and ‘I don't want to increase my activity’ (47%). Conclusions Activity trackers are a promising tool to engage people in self-monitoring a physical activity

Rapid diagnostic tests (RDTs) account for more than two-thirds of malaria diagnoses in Africa. Deletions of the Plasmodium falciparum hrp2 (pfhrp2) gene cause false-negative RDT results and have never been investigated on a national level. Spread of pfhrp2-deleted P. falciparum mutants, resistant to detection by HRP2-based RDTs, would represent a serious threat to malaria elimination efforts. Using a nationally representative cross-sectional study of 7,137 children under five years of age from the Democratic Republic of Congo (DRC), we tested 783 subjects with RDT-/PCR+ results using PCR assays to detect and confirm deletions of the pfhrp2 gene. Spatial and population genetic analyses were employed to examine the distribution and evolution of these parasites. We identified 149 pfhrp2-deleted parasites, representing 6.4% of all P. falciparum infections country-wide (95% confidence interval 5.1-8.0%). Bayesian spatial analyses identified statistically significant clustering of pfhrp2 deletions near Kinshasa and Kivu. Population genetic analysis revealed significant genetic differentiation between wild-type and pfhrp2-deleted parasite populations (GST = .046, p ≤ .00001). Pfhrp2-deleted P. falciparum is a common cause of RDT-/PCR+ malaria among asymptomatic children in the DRC and appears to be clustered within select communities. Surveillance for these deletions is needed, and alternatives to HRP2-specific RDTs may be necessary. © The Author 2016.

The purpose of this study was to analyze national survey data to provide estimates of prevalence of epilepsy and associated developmental disabilities and comorbid conditions. We analyzed data from Cycle 3 of Canada's National Longitudinal Survey of Children and Youth. The NLSCY captured, socio-demographic information, as well as age, sex, education, ethnicity, household income, chronic health related conditions from birth to 15 years old. The main survey question intended to identify "epilepsy", "cerebral palsy", "intellectual disability", "learning disability", and "emotional and nervous difficulties" in the population of children surveyed. Prevalence was based on the national cross-sectional sample and used 1000 bootstrap weights to account for survey design factors. Cycle 3 of the NLSCY had the largest number of patients with diagnosed epilepsy. Prevalence figures (n/1000) for epilepsy and cerebral palsy (EPI_CP), epilepsy and intellectual disability (EPI_ID), epilepsy and learning disability (EPI_LD), and epilepsy and emotional nervous difficulties (EPI_EMO_NERV) were 1.1, 1.17, 2.58 and 1.34 respectively. Amongst children with epilepsy, 43.17% reported the presence of one or more of the above comorbid conditions. These results provide an initial prevalence estimate of comorbid conditions with epilepsy in Canadian children. In a high proportion of children with epilepsy, the PMK had reported at least one comorbid disorder. These findings carry implications for health care utilization and long-term outcomes. We discuss methodological aspects related to the ascertainment of epilepsy in both surveys, and to the validity and implications of our findings. Copyright © 2014 British Epilepsy Association.

The stressful life of doctors makes them prone to burnout. We evaluated the prevalence of burnout among Hong Kong public hospital doctors and correlated burnout with job characteristics, working hours, stressors, and stress-relieving strategies. Cross-sectional survey. Hong Kong. One thousand doctors were randomly sampled from the Hong Kong Public Doctors' Association registry. Self-administered, anonymous questionnaires with postage-paid envelopes were mailed twice in early 2009. The Maslach Burnout Inventory-Human Services Survey was used for burnout assessment. According to this scale, burnout is defined as emotional exhaustion, depersonalisation, and a reduced sense of personal accomplishment. Correlation analysis, as well as univariate and multivariate analyses, were performed to assess factors associated with high degrees of burnout. RESULTS. A total of 226 questionnaires were analysed, of which 31.4% of the respondents satisfied the criteria for high burnout. They were younger and needed to work shifts, and their median year of practice was 8.5. High-burnout doctors worked similar hours per week to non-high-burnout doctors (mean ± standard deviation, 56.2 ± 12.7 vs 54.7 ± 10.9; P=0.413) and reported suicidal thoughts more often (9.9% vs 2.6%; P=0.033). Moreover, 52.2% of high-burnout doctors were dissatisfied or very dissatisfied with their jobs. 'Excessive stress due to global workload' and 'feeling that their own work was not valued by others' were the most significant stressors associated with high emotional exhaustion and depersonalisation, while 'feeling that their own work was not valued by others' and 'poor job security' correlated with low personal accomplishment. A high proportion of public doctors who responded to our survey endured high burnout. Trainees with some experience were at heightened risk. Stressors identified in this study should be addressed, so as to improve job satisfaction.

To examine the association between household food insecurity score and Z-scores of childhood nutritional status indicators. Population-based, cross-sectional survey, Nepal Demographic and Health Survey 2011. A nationally representative sample of 11 085 households selected by a two-stage, stratified cluster sampling design to interview eligible men and women. Children (n 2591) aged 0-60 months in a sub-sample of households selected for men's interview. Prevalence of moderate and severe household food insecurity was 23·2% and 19·0%, respectively, for children aged 0-60 months. Weighted prevalence rates for stunting (height-for-age Z-score (HAZ) <-2), wasting (weight-for-height Z-score (WHZ) <-2) and underweight (weight-for-age Z-score (WAZ) <-2) were 41·6% (95% CI 38·9, 44·3%), 11·5% (95% CI 9·8, 13·2%) and 30·1% (95% CI 27·5, 32·8%), respectively. Prevalences of stunting, severe stunting (HAZ<-3) and underweight by level of household food insecurity were statistically significant (P<0·001). By multiple linear regression analyses and after adjustment for sociodemographic, child and environmental factors, household food access insecurity score was associated with HAZ (β=-0·02, P=0·01) and WAZ (β=-0·01, P=0·01) but was not associated with WHZ and BMI-for-age Z-score. A 10-point increase in household food access insecurity score was associated with a decrease in HAZ of 0·2 (95% CI 0·05, 0·39) and decrease in WAZ of 0·1 (95% CI 0·03, 0·27). Our results from a nationally representative sample confirm the previously reported association of household food insecurity with stunting and underweight. Community nutrition interventions may use household food insecurity scales for identifying those households where children may be at risk of growth faltering.

Weight loss in dementia contributes to morbidity and mortality but the distribution of anthropometric change and its consistency between populations are less clear. Our aim was to investigate and compare the associations of dementia with waist and upper arm circumference in elders from seven low- and middle-income nations. Cross-sectional surveys were conducted of 15,022 residents aged 65 years and older in Cuba, Mexico, Venezuela, Peru, Dominican Republic, China, and India. Dementia was assessed using a cross-culturally validated algorithm, and anthropometric measurements were taken. Associations with dementia and dementia severity (clinical dementia rating scale) were investigated in linear regression models, with fixed-effects meta-analyses used to investigate between-country heterogeneity. Dementia and increased dementia severity were both associated with smaller arm and waist circumferences with little evidence of confounding by sociodemographic and health status. Associations between dementia/clinical dementia rating and arm circumference were homogeneous between countries (Higgins I(2) 0% and 7%, respectively), whereas those with waist circumference were more heterogeneous (Higgins I(2) 67% and 62%, respectively). Although cross-sectional, our findings are consistent with prospective observations of weight loss in dementia and suggest loss of both muscle and fat-the former being consistent across different settings and the latter being more context dependent.

Our objective was to compare obesity prevalence among human immunodeficiency virus (HIV)-infected adults receiving care and the U.S. general population and identify obesity correlates among HIV-infected men and women.Cross-sectional data was collected in 2009 to 2010 from 2 nationally representative surveys: Medical Monitoring Project (MMP) and National Health and Nutrition Examination Survey (NHANES).Weighted prevalence estimates of obesity, defined as body mass index ≥30.0 kg/m, were compared using prevalence ratios (PR, 95% confidence interval [CI]). Correlates of obesity in HIV-infected adults were examined using multivariable logistic regression.Demographic characteristics of the 4006 HIV-infected adults in MMP differed from the 5657 adults from the general U.S. population in NHANES, including more men (73.2% in MMP versus 49.4% in NHANES, respectively), black or African Americans (41.5% versus 11.6%), persons with annual incomes <$20,000 (64.5% versus 21.9%), and homosexuals or bisexuals (50.9% versus 3.9%). HIV-infected men were less likely to be obese (PR 0.5, CI 0.5-0.6) and HIV-infected women were more likely to be obese (PR1.2, CI 1.1-1.3) compared with men and women in the general population, respectively. Among HIV-infected women, younger age was associated with obesity (<40 versus >60 years). Among HIV-infected men, correlates of obesity included black or African American race/ethnicity, annual income >$20,000 and <$50,000, heterosexual orientation, and geometric mean CD4+ T-lymphocyte cell count >200 cells/μL.Obesity is common, affecting 2 in 5 HIV-infected women and 1 in 5 HIV-infected men. Correlates of obesity differ for HIV-infected men and women; therefore, different strategies may be needed for the prevention and treatment.

Fourier transform infrared absorption cross-sections of pure propane (C3H8) and propane broadened with H2 have been calculated from transmittance spectra recorded at temperatures from 292 K to 205 K. Transmittance spectra were recorded at the Canadian Light Source (CLS) Far-Infrared beamline, utilizing both the synchrotron source and the internal glowbar source. The absorption cross-sections have been calibrated to Pacific Northwest National Laboratory (PNNL) reference cross-sections of propane and can be used to interpret astronomical observations of giant planets such as Jupiter and Saturn as well as exoplanets.

In the past 3 years, 6 volleyball players with ischemic digits and small microemboli in the digital arteries of the dominant hand presented themselves in our hospital. These complaints were caused by an aneurysmatic dilation of the posterior circumflex humeral artery (PCHA) with distal occlusion and digital emboli in the isolateral limb. All were elite male volleyball players active in the national top league. Little is known about the exact symptoms associated with PCHA pathological lesions with digital emboli (PCHAP with DE) and its prevalence in elite volleyball players. If vascular injury can be identified at an early stage, thromboembolic complications and irreversible damage to the digits might be prevented. To assess the prevalence of symptoms that are consistent with digital ischemia and may be caused by PCHAP with DE in elite male volleyball players in the Netherlands. Cross-sectional study; Level of evidence, 3. A questionnaire survey was performed among elite volleyball players in the Dutch national top league and the Dutch beach volleyball team. The questionnaire was constructed using literature-based data on symptoms associated with PCHAP with DE, together with data retrieved from medical files. A total of 99 of the 107 athletes participated, with a response rate of 93%. The most frequently reported symptoms associated with PCHAP with DE were cold, blue, or pale digits in the dominant hand during or immediately after practice or competition. The prevalence of these symptoms ranged from 11% to 27%. The prevalence of cold digits during practice and competition was 27%. The prevalence of cold, blue, and pale digits during or immediately after practice and competition was 12%. An unexpectedly high percentage of elite volleyball players reported symptoms that are associated with PCHAP with DE in the dominant hand. Because these athletes are considered potentially at risk for developing critical digital ischemia, further analysis of the presence of digital

The Great East Japan earthquake, subsequent tsunamis and the Fukushima nuclear incident had a tremendous impact on Japanese society. Although small-scale surveys have been conducted in highly affected areas, few have elucidated the disaster's effect on health from national perspective, which is necessary to prepare national policy and response. The aim of the present study was to describe prefecture-level health status and investigate associations with number of aftershocks, seismic intensity, a closer geographical location to the Fukushima Nuclear Power Plant, or higher reported radiation dose in each prefecture even after adjusting for individual socioeconomic factors, by utilizing individual-level data acquired from a national cross-sectional Internet survey as well as officially reported prefecture-level data. A Japanese government research institute obtained 12,000 participants by quota sampling and 7335 participants were eligible for the analysis in an age range between 17 and 27 years old. We calculated the percentage of people with decreased subjective health in each prefecture after the earthquake. Variability introduced by a small sample size for some prefectures was smoothed using empirical Bayes estimation with a random-intercept logistic model, with and without demographic factors. Multilevel logistic regression was used to calculate adjusted odds ratios (ORs) for change of subjective health associated with prefecture-level and individual-level factors. Adjusted empirical Bayes estimates were higher for respondents commuting in the northeast region (Iwate 14%, Miyagi 19%, and Fukushima 28%), which faces the Pacific Ocean, while the values for Akita (10%) and Yamagata (8%) prefectures, which do not face the Pacific Ocean, were lower than those of Tokyo (12%). The values from the central to the western region were clearly lower. The number of aftershocks was coherently associated with decreased health (OR 1.05 per 100 times, 95% CI 1.04-1.06; P<.001

Objectives: This study examined the patterns and determinants of current smoking and intention to smoke among secondary school students of Han and Tujia nationalities in China. Methods: A cross-sectional survey was conducted in three regions, namely, Chongqing, Liaocheng, and Tianjin, of China in 2015. A structured self-administered questionnaire was used for data collection. Results: Of the total subjects ( n = 1805), 78.9% were ethnic Han and 21.1% were ethnic Tujia. Overall 9.4% (Han: 7.7%; Tujia: 15.5%) secondary school students were smokers and 37.28% smoked more than once per day. Of the non-smoker students ( n = 1636), 17.4% have an intention to smoke. A total of 81.1% of students reportedly had never been taught throughout school about smoking or tobacco prevention. When compared to the students who were taught in the school about smoking or tobacco prevention (18.90%) students who were never taught were more likely to smoke (OR = 2.39; 95% CI = 1.14-5.01). As compared to Han nationality students who were from Tujia nationality were more likely to smoke (OR = 2.76; 95% CI = 1.88-4.04) and were more likely to have a higher frequency of smoking (95% CI (0.88, 0.88), p = 0.010). Non-smokers who were high school students (OR = 4.29; 95% CI = 2.12-8.66), whose academic performance were situated in the last 25% (OR = 2.23; 95% CI = 1.48-3.34) and lower than 50% (OR = 1.50; 95% CI = 1.02-2.20) were more likely to have an intention of smoking. Conclusions: About one in ten secondary school students was a smoker, one in three smokers smoked more than one time per day, and a quarter of non-smokers had an intention of smoking in China. Smoking rate was higher among students from Tujia than the Han nationality. This study provided some important information for future tobacco control programs among secondary school students in the ethnic minority autonomous region and minority settlements in a multi-ethnic country.

Neutron capture and β- -decay are competing branches of the s-process nucleosynthesis path at 85Kr [1], which makes it an important branching point. The knowledge of its neutron capture cross section is therefore essential to constrain stellar models of nucleosynthesis. Despite its importance for different fields, no direct measurement of the cross section of 85Kr in the keV-regime has been performed. The currently reported uncertainties are still in the order of 50% [2, 3]. Neutron capture cross section measurements on a 4% enriched 85Kr gas enclosed in a stainless steel cylinder were performed at Los Alamos National Laboratory (LANL) using the Detector for Advanced Neutron Capture Experiments (DANCE). 85Kr is radioactive isotope with a half life of 10.8 years. As this was a low-enrichment sample, the main contaminants, the stable krypton isotopes 83Kr and 86Kr, were also investigated. The material was highly enriched and contained in pressurized stainless steel spheres.

Prospective studies exploring the associations between a large range of occupational factors and psychotropic drug use among national samples of workers are seldom. This study investigates the cross-sectional and prospective associations between occupational factors, including a large set of psychosocial work factors, and psychotropic drug use in the national French working population. The study sample comprised 7542 workers for the cross-sectional analysis and 4213 workers followed up for a 4-year period for the prospective analysis. Psychotropic drug use was measured within the last 12 months and defined by the use of antidepressants, anxiolytics or hypnotics. Three groups of occupational factors were explored: classical and emergent psychosocial work factors, working time/hours and physical work exposures. Weighted Poisson regression analyses were performed to adjust for covariates. In the cross-sectional analysis, psychological demands, low social support and hiding emotions were associated with psychotropic drug use. Job insecurity for men and night work for women were associated with psychotropic drug use. In the prospective analysis, hiding emotions and physical exposure were predictive of psychotropic drug use. Dose-response associations were observed for the frequency/intensity of exposure and repeated exposure to occupational factors. This study underlines the role of psychosocial work factors, including emergent factors, in psychotropic drug use. Prevention policies oriented toward psychosocial work factors comprehensively may be useful to reduce this use. Copyright © 2015 Elsevier Ltd. All rights reserved.

Professional quality of life among healthcare providers can impact the quality and safety of patient care. The purpose of this research was to investigate compassion satisfaction and compassion fatigue levels as measured by the Professional Quality of Life Scale self-report instrument in a community hospital in the United States. A cross-sectional survey study examined differences among 139 RNs, physicians, and nursing assistants. Relationships among individual and organizational variables were explored. Caregivers for critical patients scored significantly lower on the Professional Quality of Life subscale of burnout when compared with those working in a noncritical care unit. Linear regression results indicate that high sleep levels and employment in critical care areas are associated with less burnout. Identification of predictors can be used to design interventions that address modifiable risks. © 2013 Wiley Publishing Asia Pty Ltd.

To describe the prevalence of and risk factors for experiencing "phantom vibrations," the sensory hallucination sometimes experienced by people carrying pagers or cell phones when the device is not vibrating. Cross sectional survey. Academic medical centre. 176 medical staff who responded to questionnaire (76% of the 232 people invited). Measurements Electronic survey consisting of 17 questions about demographics, device use, phantom vibrations experienced, and attempts to stop them. Of the 169 participants who answered the question, 115 (68%, 95% confidence interval 61% to 75%) reported having experienced phantom vibrations. Most (68/112) who experienced phantom vibrations did so after carrying the device between 1 month and 1 year, and 13% experienced them daily. Four factors were independently associated with phantom vibrations: occupation (resident v attending physician, prevalence ratio 1.47, 95% confidence interval 1.10 to 1.97), device location (breast pocket v belt, prevalence ratio 1.66, 1.29 to 2.14), hours carried (per 6 hour increment, prevalence ratio 1.30, 1.07 to 1.58), and more frequent use in vibrate mode (per frequency category, prevalence ratio 1.18, 1.03 to 1.34). Of those who experienced phantom vibrations, 43 (39%, 30% to 48%) were able to stop them. Strategies for stopping phantom vibrations included taking the device off vibrate mode, changing the location of the device, and using a different device (success rates 75% v 63% v 50%, respectively, P=0.217). However, 39% (30% to 49%) of respondents did not attempt any strategies. Phantom vibration syndrome is common among those who use electronic devices.

Background Guatemala is presently engaged in the Central America Initiative to interrupt Chagas disease transmission by reducing intradomiciliary prevalence of Triatoma dimidiata, using targeted cross-sectional surveys to direct control measures to villages exceeding the 5% control threshold. The use of targeted surveys to guide disease control programs has not been evaluated. Here, we compare the findings from the targeted surveys to concurrent random cross-sectional surveys in two primary foci of Chagas disease transmission in central and southeastern Guatemala. Methodology/Principal Findings Survey prevalences of T. dimidiata intradomiciliary infestation by village and region were compared. Univariate logistic regression was used to assess the use of risk factors to target surveys and to evaluate indicators associated with village level intradomiciliary prevalences >5% by survey and region. Multivariate logistic regression models were developed to assess the ability of random and targeted surveys to target villages with intradomiciliary prevalence exceeding the control threshold within each region. Regional prevalences did not vary by survey; however, village prevalences were significantly greater in random surveys in central (13.0% versus 8.7%) and southeastern (22.7% versus 6.9%) Guatemala. The number of significant risk factors detected did not vary by survey in central Guatemala but differed considerably in the southeast with a greater number of significant risk factors in the random survey (e.g. land surface temperature, relative humidity, cropland, grassland, tile flooring, and stick and mud and palm and straw walls). Differences in the direction of risk factor associations were observed between regions in both survey types. The overall discriminative capacity was significantly greater in the random surveys in central and southeastern Guatemala, with an area under the receiver-operator curve (AUC) of 0.84 in the random surveys and approximately 0.64 in the

The aim of the study was to determine whether international students have greater risk-taking behaviours that could lead to importing novel and resistant strains of sexually transmitted infections (STIs). We conducted a cross-sectional web-based survey of university students' sexual behaviour, alcohol and drug use, and self-reported diagnosis of STIs and compared these between British and international students. In all, 827 students completed the survey, of whom 123 (15%) were international students. International students were less likely to have ever drunk alcohol (95.4% versus 87.8%, P = 0.002) and used drugs (56.4% versus 41.5%, P = 0.002). International students were on average almost two years older at first intercourse (18.7 versus 17 years; P < 0.001). There were no differences in the number of sexual partners between national and international students. On a discriminant analysis model, international students were characterized by being older and from a non-white background, less likely to use cocaine, they drank alcohol less frequently and were more likely to have had unprotected intercourse with two or more partners in the previous year. In conclusion, international students tend to drink more moderately and use fewer recreational drugs than British students. However, they exhibit higher sexual risk behaviours that could lead to importing novel and resistant strains of STIs.

Recent changes to the organisation and delivery of primary care in the UK have the potential to reduce continuity of care markedly, but it is not clear how this will have an impact on patient trust. This study aims to test the associations between specific aspects of continuity in the GP-patient relationship, and patient trust, informed by the theoretical framework of behavioural game theory. A cross-sectional survey of patients in three Leicestershire general practices was conducted. Regression analysis showed that ratings of the GP's interpersonal care, past experience of cooperation, and expectation of continuing care from the GP were all independent predictors of patient trust. These findings highlight the value of longitudinal aspects of the GP-patient relationship.

The Korea National Health and Nutrition Examination Survey (KNHANES) is a national surveillance system that has been assessing the health and nutritional status of Koreans since 1998. Based on the National Health Promotion Act, the surveys have been conducted by the Korea Centers for Disease Control and Prevention (KCDC). This nationally representative cross-sectional survey includes approximately 10 000 individuals each year as a survey sample and collects information on socioeconomic status, health-related behaviours, quality of life, healthcare utilization, anthropometric measures, biochemical and clinical profiles for non-communicable diseases and dietary intakes with three component surveys: health interview, health examination and nutrition survey. The health interview and health examination are conducted by trained staff members, including physicians, medical technicians and health interviewers, at a mobile examination centre, and dieticians' visits to the homes of the study participants are followed up. KNHANES provides statistics for health-related policies in Korea, which also serve as the research infrastructure for studies on risk factors and diseases by supporting over 500 publications. KCDC has also supported researchers in Korea by providing annual workshops for data users. KCDC has published the Korea Health Statistics each year, and microdata are publicly available through the KNHANES website (http://knhanes.cdc.go.kr).

The present shortage of registered nurses (RNs) in many European countries is expected to continue and worsen, which poses a substantial threat to the maintenance of healthcare in this region. Work-family conflict is a known risk factor for turnover and sickness absence. This paper empirically examines whether the nurse practice environment is associated with experienced work-family conflict. A multilevel model was fit with the individual RN at the 1st, and the hospital department at the 2nd level using cross-sectional RN survey data from the Swedish part of RN4CAST, an EU 7th framework project. The data analyzed here is based on a national sample of 8356 female and 592 male RNs from 369 hospital departments. We found that 6% of the variability in work-family conflict experienced by RNs was at the department level. Organizational level factors significantly accounted for most of the variability at this level with two of the work practice environment factors examined, staffing adequacy and nurse involvement in hospital affairs, significantly related to work-family conflict. Due to the design of the study, factors on ward and work group levels could not be analyzed, but are likely to account for additional variance which in the present analysis appears to be on the individual level, with private life factors likely explaining another major part. These results suggest that higher level organizational factors in health care have a significant impact on the risk of work-family conflict among RNs through their impact on the nurse practice environment. Lower level organizational factors should be investigated in future studies using hierarchical multilevel sampling. Copyright © 2013 The Authors. Published by Elsevier Ltd.. All rights reserved.

The aim of this study was to analyse the clustering of multiple health-related behaviours among adolescents and describe which socio-demographic characteristics are associated with these patterns. Cross-sectional study. Brazilian schools assessed by the National Survey of School Health (PeNSE, 2012). 104 109 Brazilian ninth-grade students from public and private schools (response rate=82.7%). Exploratory and confirmatory factor analyses were performed to identify behaviour clustering and linear regression models were used to identify socio-demographic characteristics associated with each one of these behaviour patterns. We identified a good fit model with three behaviour patterns. The first was labelled 'problem-behaviour' and included aggressive behaviour, alcohol consumption, smoking, drug use and unsafe sex; the second was labelled 'health-compromising diet and sedentary behaviours' and included unhealthy food indicators and sedentary behaviour; and the third was labelled 'health-promoting diet and physical activity' and included healthy food indicators and physical activity. No differences in behaviour patterns were found between genders. The problem-behaviour pattern was associated with male gender, older age, more developed region (socially and economically) and public schools (compared with private). The 'health-compromising diet and sedentary behaviours' pattern was associated with female gender, older age, mothers with higher education level and more developed region. The 'health-promoting diet and physical activity' pattern was associated with male gender and mothers with higher education level. Three health-related behaviour patterns were found among Brazilian adolescents. Interventions to decrease those negative patterns should take into account how these behaviours cluster together and the individuals most at risk. Published by the BMJ Publishing Group Limited.

Despite the rising childhood obesity rates, few studies have examined the association between access to recreational parks and facilities and obesity. A cross-sectional study was performed among 42 278 US children who participated in the 2007 National Survey of Children's Health. Access to parks and recreational facilities was self-reported by parents, and body mass index was calculated from parents' self-report of the child's height and weight. Logistic regression was used to obtain ORs and 95% CIs. Since obesity was not a rare occurrence, an OR correction method was used to provide a more reliable estimate of the prevalence ratio (PR). Children with access to parks and facilities had decreased prevalence of obesity as compared to children without access (PR=0.79, 95% CI 0.69 to 0.91). After adjustment for covariates, the magnitude of the association remained unchanged; however, results were no longer statistically significant (PR=0.77, 95% CI 0.55 to 1.07). Race/ethnicity was an effect modifier of the access-obesity relationship (p<0.0001). Among Non-Hispanic White children, there was no strong association (PR=0.89, 95% CI 0.64 to 1.23). However, among Non-Hispanic Black children, those who had access to recreational parks and facilities had 0.40 times the prevalence of obesity as compared to those without access, and this result was statistically significant (95% CI 0.17 to 0.90). This research highlights potential health disparities in childhood obesity due to limited access to recreational parks and facilities. Additional studies are needed to further investigate this association. If confirmed, providing safe, accessible parks and facilities may be one way to combat childhood obesity, particularly among minority children.

Purpose The purpose of this study was to determine if there was an association between receipt of diet/nutrition, exercise, and weight loss education in adult patients with a primary diagnosis of diabetes with various demographic and socioeconomic variables using data from the National Ambulatory Medical Care Survey (NAMCS) for the years 2008 to 2011. Methods This retrospective, cross-sectional, observational study design included patients ≥ 18 years of age with diabetes in the NAMCS between 2008 and 2011, inclusive. A series of weighted multivariable logistic regression models was constructed to evaluate predictors of diet/nutrition, exercise, and weight loss education. Odds ratios and 95% confidence intervals were reported. Results Among patients included in this study (n = 3027), 35.6% received diet/nutrition education, 21.8% received exercise education, and 13.6% received weight loss education. From the multivariable analyses, visits using "other" payment type, visits with Medicaid, and visits occurring in non-Metropolitan Statistical Areas were significantly less likely to receive diet/nutrition education; visits using other payment type, visits in non-Metropolitan Statistical Areas, and visits by those ≥ 65 and 45-64 years of age were significantly less likely to receive exercise education. No significant disparities in the receipt of weight loss education were found. Conclusion These findings indicate that although only approximately one third or fewer patients diagnosed with diabetes were receiving diet/nutrition, exercise, or weight loss education, there appeared to be limited disparities among the groups studied. Education rates appear to be trending upward over time, to be slightly improved as compared with previous studies, and to include fewer disparities.

Identification and characterisation of dietary patterns are needed to define public health policies to promote better food behaviours. The aim of this study was to identify the major dietary patterns in the French adult population and to determine their main demographic, socio-economic, nutritional and environmental characteristics. Dietary patterns were defined from food consumption data collected in the second French national cross-sectional dietary survey (2006-2007). Non-negative-matrix factorisation method, followed by a cluster analysis, was implemented to derive the dietary patterns. Logistic regressions were then used to determine their main demographic and socio-economic characteristics. Finally, nutritional profiles and contaminant exposure levels of dietary patterns were compared using ANOVA. Seven dietary patterns, with specific food consumption behaviours, were identified: 'Small eater', 'Health conscious', 'Mediterranean', 'Sweet and processed', 'Traditional', 'Snacker' and 'Basic consumer'. For instance, the Health-conscious pattern was characterised by a high consumption of low-fat and light products. Individuals belonging to this pattern were likely to be older and to have a better nutritional profile than the overall population, but were more exposed to many contaminants. Conversely, individuals of Snacker pattern were likely to be younger, consumed more highly processed foods, had a nutrient-poor profile but were exposed to a limited number of food contaminants. The study identified main dietary patterns in the French adult population with distinct food behaviours and specific demographic, socio-economic, nutritional and environmental features. Paradoxically, for better dietary patterns, potential health risks cannot be ruled out. Therefore, this study demonstrated the need to conduct a risk-benefit analysis to define efficient public health policies regarding diet.

To report total fluid intake (TFI) and the intake of different fluid types in adults (≥ 18 years old) from Mexico, Argentina, Brazil and Uruguay. To compare intakes between countries and with recommended adequate intake (AI) of water from fluids. Cross-sectional data were collected using a validated liquid intake 7-day record (Liq.In 7 ) in populations from Argentina (n = 1089), Brazil (n = 477), Mexico (n = 1677) and Uruguay (n = 554). Population characteristics, including age, gender, body mass index and socioeconomic level were recorded. Mean TFI was compared with the AI of water from fluids set by the USA Institute of Medicine. The lowest TFI was recorded in Mexican women (1748 mL/day) and the highest in Argentinean men (2318 mL/day). Median daily TFI was significantly different between countries; Uruguay and Argentina had higher values than Mexico and Brazil. In the former, plain water contributed to only 25% of TFI, the remainder being predominantly from hot beverages. Approximately, a third of adults did not drink enough fluid to meet the recommended AI. High SSB consumption was reported, which was significantly different between countries (p < 0.05), the highest being in Mexico (median 25-75th percentiles): 531 (300-895 mL/day. This survey highlights the need to increase water consumption and reduce SSB intake in this region to avoid potential associated health risks. These findings may be useful information in monitoring public health policy strategies.

Research concerning ethnocultural bullying and adolescent health in China remains extremely limited. This study among Chinese urban adolescents examines associations between ethnocultural bullying and eight health-related outcomes: suicidal ideation, suicide planning, depressive symptomology, anxiety symptomatology, fighting, injury intentionally inflicted by another, smoking and moderate/heavy alcohol consumption. Data were obtained from the World Health Organisation's 2003 Chinese Global School-based Health Survey, a cross-sectional national survey of urban adolescents in four Chinese cities. The analytic sample size was n = 8182, which represented a sampling frame of 769,835 adolescents. Statistical analysis was conducted using generalised linear mixed effects models and sampling weights. Prevalence of ethnocultural bullying was significantly higher in Urumqi, Xinjiang province (2.08%) compared with Beijing municipality (0.72%) or Wuhan, Hubei province (0.67%). Compared to participants who were not bullied, religious bullying victimisation was significantly associated with suicidal ideation, injury intentionally inflicted by another and depressive symptomology. Racial bullying victimisation was significantly associated with suicidal ideation, injury intentionally inflicted by another and among females but not males, depressive symptomology. Health effects of ethnocultural bullying appear to be distinct from that of bullying in general. Additional research on ethnocultural adolescent health issues in China is warranted.

A cross-sectional survey was carried out to investigate the seroprevalence of ovine and bovine brucellosis in the livestock-wildlife interface area of Nechisar National Park, Ethiopia. Furthermore, producer's knowledge about brucellosis and its zoonotic potential was assessed using a structured questionnaire. A total of 268 cattle and 246 goat sera were collected from 50 herds and 46 flocks and subjected to Rose Bengal test (RBT) and enzyme-linked immunosorbent assay (ELISA) in parallel to detect anti-Brucella species antibodies. Positive reactions were further confirmed with compliment fixation test (CFT). Flock and herd level seroprevalence rate was 12.8% (95% CI 4.8-25.7) and 32.0% (95% CI 19.5-46.7) in goats and cattle, respectively. An overall animal-level seroprevalence of 4.5% (95% CI 2.25-7.86) and 9.7% (95% CI 6.44-13.89) was recorded for goats and cattle, respectively. Seroprevalence showed an increasing trend with age, where adult cattle > 2 years. Goats (> 1 year) recorded relatively higher seroprevalence, but the differences were not statistically significant. Similarly, female cattle and goats recorded a relatively higher seroprevalence, 11 and 5.6%, respectively, compared to males but the difference was not significant. However, a significant (P < 0.01) variation of seroprevalence was noted for parity (bovine), higher in animals in second parity, and abortion history, in both species, higher in animals that experienced abortion. Interviews revealed lack of awareness about brucellosis and food safety related to the zoonotic potential from consuming raw animal products (milk and meat). Ninety-eight percent of respondents did not consider handling abortion material is risky, and only a very low proportion (8%, n = 50) was able to mention limited zoonotic diseases (anthrax and Taenia cysticercosis) could be transmissible to people. The study indicated that brucellosis is endemic in domestic animals in the interface area and calls for further

To examine the association between household food insecurity (HFI) and risk of childhood stunting and to determine whether this association is modified by maternal-child overweight/obesity. Observational cross-sectional study. Data come from the Mexican National Health and Nutrition Survey ( ENSANUT 2012 by its initials in Spanish), representative of rural and urban areas. Our study sample included 5087 mother-preschool child pairs and 7181 mother-schoolchild pairs. Differences in the prevalence (95% CI) of each HFI category by socioeconomic characteristics and maternal-child nutritional status were estimated. A logistic regression model was conducted for stunting and overweight among preschool children and for stunting and overweight/obesity among schoolchildren, adjusting for pertinent covariates. HFI was measured according to the Latin American and Caribbean Food Security Scale (ELCSA by its initials in Spanish). Weight and recumbent lenght or height measures were obtained from children. Overweight and obesity in women were determined according to the WHO Growth Reference Charts. The following covariates were included: sex of the child. urbanicity (urban/rural), region of residence and maternal education. Benefiting from food assistance programmes and socioeconomic status index were also included. Results were expressed as adjusted ORs. Stunting proved more prevalent in preschool children with moderate or severe HFI (16.2% and 16.8%, respectively) (p=0.036 and p=0.007, respectively) than in their counterparts with mild or no HFI (13.2% and 10.7%, respectively). Furthermore, the interaction between HFI and maternal obesity had a significant impact on stunting in preschool children (p<0.05). Severe HFI increased risk of stunting in children with non-obese mothers but not in those with obese mothers. We have discovered a new relationship between HFI and maternal obesity on the one hand and risk of childhood stunting on the other hand. This may reflect a shared

The National Bureau of Standards (NBS) has maintained a data base of experimental and theoretical photon absorption cross sections (attenuation coefficients) since 1950. Currently the measured data include more than 20,000 data points abstracted from more than 500 independen.t literature sources including both published and unpublished reports and private communications. We have recently completed a systematic comparison over the energy range 0.1-100 keV of the measured cross sections in the NBS data base with cross sections obtained using the photoionization cross sections calculated by Scofield and the semi-empirical set of recommended photoionization cross section values of Henke et al. Cross sections for coherent and incoherent scattering were added to that of photoionization to obtain a value which could be compared to the experimental results. At energies above 1 keV, agreement between theory and experiment is rather good except for some special situations which prevent the accurate description of the measured samples as free atoms. These include molecular effects near absorption edges and solid state and crystal effects (such as for silicon). Below 1 keV the comparison indicates the range of atomic numbers and energies where the theory becomes inapplicable. The results obtained using Henke et al. agree well with the measured data when such data exist, but there are many elements for which data are not available over a wide range of energies. Comparisons with other theoretical data are in progress. This study also enabled us to show that a suggested renormalization procedure to the Scofield calculation (from dartree-Slater to Hartree-Fock) worsened the agreement between the theory and experiment. We have recently developed a PC-based computer program to generate theoretical cross section values based on Scofield's calculation. We have also completed a related program to enable a user to extract selected data from the measured data base.

This study assessed students' attitudes toward science in Qatar. A cross-sectional, nationwide probability sample representing all students enrolled in grades 3 through 12 in the various types of schools in Qatar completed the 'Arabic Speaking Students' Attitudes toward Science Survey' (ASSASS). The validity and reliability of the 32-item instrument, encompassing five sub-scales, have already been shown to be robust. The present analysis focused on responses from 1978 participants representing the students who completed the ASSASS in Arabic. Descriptive statistics were computed and a competing pair of multiple indicators multiple causes models is presented that attempt to link patterns in students' responses to the ASSASS with a set of indicators. The final model retained student age, gender, nationality (i.e. Qatari vs. Non-Qatari Arab), and school type as indicators. Findings from this study suggest that participants' attitudes toward science decrease with age, and that these attitudes and related preferences are influenced by students' nationality and the type of school they attend. Equally important, the often-reported advantages for male over female precollege students in terms of attitudes toward science were much less prominent in the present study.

Domestic violence is a major public health problem. A wide range of health hazards result from violence against women directly, or from its long-term consequences. The objective of this study is to determine health related consequences of domestic violence against women. A community based cross-sectional study was carried through online survey; convenience sample was taken during the period between December 2013 and February 2014. 421 women completed the survey, who met the inclusion criteria and accepted willing to be a part of this study. The data was collected through online survey website. A validated Arabic version of NorVold Domestic Abuse Questionnaire (NOVAQ) was used as a tool to assess domestic violence among the study sample. Analysis was performed using SPSS, version 18.0. A total of 421 women participated in the survey. There was no significant correlation between socio-demographic characteristics and being abused or not. However, by further analysis we found more sexual abuse among non-working women P=0.048. There was significant correlation between abused women and general health status, doctor visits, depression, insomnia, and somatic symptoms. The consequences of abuse are profound, extending beyond the health of individual to affect the well-being of entire community. So, we recommend to increase community awareness through national awareness campaign, national prevalence survey of domestic violence and well trained health professionals for assessing domestic violence cases.

Background Health-state utilities for prisoners have not been described. Methods We used data from a 1996 cross-sectional survey of Australian prisoners (n = 734). Respondent-level SF-36 data was transformed into utility scores by both the SF-6D and Nichol's method. Socio-demographic and clinical predictors of SF-6D utility were assessed in univariate analyses and a multivariate general linear model. Results The overall mean SF-6D utility was 0.725 (SD 0.119). When subdivided by various medical conditions, prisoner SF-6D utilities ranged from 0.620 for angina to 0.764 for those with none/mild depressive symptoms. Utilities derived by the Nichol's method were higher than SF-6D scores, often by more than 0.1. In multivariate analysis, significant independent predictors of worse utility included female gender, increasing age, increasing number of comorbidities and more severe depressive symptoms. Conclusion The utilities presented may prove useful for future economic and decision models evaluating prison-based health programs. PMID:19715571

Study explanatory forms often state that an ethics committee has approved a research project. To determine whether the lay community understand the roles of ethics committees in research, we took a cross-sectional national sample from three sampling frames: the general population (n=1532); cohort study participants (n=397); and case-control study participants (n=151). About half (51.3%) of the participants had heard of ethics committees. Those who had were more likely to be those who had participated in previous surveys, older participants, those born in Australia and those with higher education. Almost all participants agreed that the roles of an ethics committee were to protect participants' privacy and ensure no harm came to study participants and most agreed that the committee's role was to ensure that the research was capable of providing answers. Case-control and cohort participants were more likely than the general population to consider that the role of an ethics committee was to design the research and obtain research funding. Overall, we found that about half of the population are aware of ethics committees and that most could correctly identify that ethics committees are there to protect the welfare and rights of research participants, although a substantial minority had some incorrect beliefs about the committees' roles. Increased education, particularly for migrants and older people, might improve understanding of the role of ethics committees in research. Published by the BMJ Publishing Group Limited.

Obesity is highly related to negative reproductive health outcomes, but its relationship with spontaneous abortion and stillbirth remains to be understood, especially in transitioning economies. This study aimed to examine the relationship between obesity and spontaneous abortions and stillbirths in a representative sample of the Brazilian population. Cross-sectional study using secondary data of Brazilian women of reproductive age (15-45 years old) from the National Demographic and Health Survey in 2006. Obesity was measured by body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHR). Logistic regression modeling of the survey data was used to evaluate the relationship between obesity and the study outcomes. The three obesity markers used were found to be strongly and positively associated with spontaneous abortion and stillbirth occurrence. In the adjusted models, there was strong evidence that for each unit increase in BMI (OR = 1.05; 95%CI: 1.02-1.08) and WHR (OR = 1.32; 95%CI: 1.03-1.69), the odds of having a spontaneous abortion was higher. In addition, compared to those of optimal weight, obese women were more likely to have negative outcomes. Maternal age, parity, skin color, educational level and household income were important covariates for adjustment. A sensitivity analysis among women who had only one pregnancy was also performed and showed similar results. Obesity is potentially associated with an increased risk of spontaneous abortion and stillbirth in a representative sample of the Brazilian population. These findings are in accordance with previous studies and thus reinforce the need for obstetric care providers to counsel obese reproductive-age women regarding the risks, complications and importance of weight loss and weight control prior to pregnancy.

Selective reporting of antibiotic susceptibility test (AST) results is one possible laboratory-based antibiotic stewardship intervention. The primary aim of this study was to identify where and how selective reporting of AST results is implemented in Europe both in inpatient and in outpatient settings. An ESCMID cross-sectional, self-administered, internet-based survey was conducted among all EUCIC (European Committee on Infection Control) or EUCAST (European Committee on Antimicrobial Susceptibility Testing) national representatives in Europe and Israel. Of 38 countries, 36 chose to participate in the survey. Selective reporting of AST results was implemented in 11/36 countries (31%), was partially implemented in 4/36 (11%) and was limited to local initiatives or was not adopted in 21/36 (58%). It was endorsed as standard of care by health authorities in only three countries. The organisation of selective reporting was everywhere discretionally managed by each laboratory, with a pronounced intra- and inter-country variability. The most frequent application was in uncomplicated community-acquired infections, particularly urinary tract and skin and soft-tissue infections. The list of reported antibiotics ranged from a few first-line options, to longer reports where only last-resort antibiotics were hidden. Several barriers to implementation were reported, mainly lack of guidelines, poor system support, insufficient resources, and lack of professionals' capability. In conclusion, selective reporting of AST results is poorly implemented in Europe and is applied with a huge heterogeneity of practices. Development of an international framework, based on existing initiatives and identified barriers, could favour its dissemination as one important element of antibiotic stewardship programmes.

Beverage consumption data were obtained by 1 d food records in an individual dietary survey. Nationwide cross-sectional survey, 2008-2009. Nationally representative sample of individuals aged ≥10 years (n 34 003). Beverages contributed 17.1 % of total energy consumption. Caloric coffee beverages provided the greatest level of energy overall (464 kJ (111 kcal)/d). Individuals aged 10-18 years (243 kJ (58 kcal)/d) and 19-39 years (230 kJ (55 kcal)/d) consumed a higher proportion of energy from sugar-sweetened soft drinks than individuals over this age (142 kJ (34 kcal)/d for those aged 40-59 years and 79 kJ (19 kcal)/d for those aged ≥60 years). Overall, the contribution of beverages, particularly sugary beverages, to total energy consumption in Brazil represents an important public health challenge and is comparable with those from other countries.

Labor force surveys conducted over time by the rotating panel design have been carried out in many countries, including Indonesia. Labor force survey in Indonesia is regularly conducted by Statistics Indonesia (Badan Pusat Statistik-BPS) and has been known as the National Labor Force Survey (Sakernas). The main purpose of Sakernas is to obtain information about unemployment rates and its changes over time. Sakernas is a quarterly survey. The quarterly survey is designed only for estimating the parameters at the provincial level. The quarterly unemployment rate published by BPS (official statistics) is calculated based on only cross-sectional methods, despite the fact that the data is collected under rotating panel design. The study purpose to estimate a quarterly unemployment rate at the district level used small area estimation (SAE) model by combining time series and cross-sectional data. The study focused on the application and comparison between the Rao-Yu model and dynamic model in context estimating the unemployment rate based on a rotating panel survey. The goodness of fit of both models was almost similar. Both models produced an almost similar estimation and better than direct estimation, but the dynamic model was more capable than the Rao-Yu model to capture a heterogeneity across area, although it was reduced over time.

Study Objectives: Sleep bruxism (SB) is characterized by tooth grinding and jaw clenching during sleep. Familial factors may contribute to the occurrence of SB. This study aims are: (1) revisit the prevalence and characteristics of SB in a large cross-sectional survey and assess familial aggregation of SB, (2) assess comorbidity such as insomnia and pain, (3) compare survey data in a subset of subjects diagnosed using polysomnography research criteria. Methods: A sample of 6,357 individuals from the general population in Quebec, Canada, undertook an online survey to assess the prevalence of SB, comorbidities, and familial aggregation. Data on familial aggregation were compared to 111 SB subjects diagnosed using polysomnography. Results: Regularly occurring SB was reported by 8.6% of the general population, decreases with age, without any gender difference. SB awareness is concomitant with complaints of difficulties maintaining sleep in 47.6% of the cases. A third of SB positive probands reported pain. A 2.5 risk ratio of having a first-degree family member with SB was found in SB positive probands. The risk of reporting SB in first-degree family ranges from 1.4 to 2.9 with increasing severity of reported SB. Polysomnographic data shows that 37% of SB subjects had at least one first-degree relative with reported SB with a relative risk ratio of 4.625. Conclusions: Our results support the heritability of SB-tooth grinding and that sleep quality and pain are concomitant in a significant number of SB subjects.

Health care is a demanding field, with a high level of responsibility and exposure to emotional and physical danger. High levels of stress may result in depression, anxiety, burnout syndrome, and in extreme cases, post-traumatic stress disorder. The aim of this study was to determine which personal, professional, and organizational variables are associated with greater perceived stress among critical care nurses for purposes of developing integrative solutions to decrease stress in the future. We conducted a correlation research survey using a cross-sectional design and an in-person survey method. The questionnaire consisted of 2 parts: (1) socioeconomic, professional, and institutional variables and (2) work stressors. Surveys were conducted between January 1, 2011, and December 1, 2015. Multistage cluster random sampling was utilized for data collection. Inclusion criteria were (1) age ≥18 years, (2) registered nurse, (3) works in the intensive care unit (ICU), and (4) willing and able to complete the survey. We surveyed 21 767 ICU nurses in Iran and found that male sex, lower levels of peer collaboration, working with a supervisor in the unit, nurse-patient ratios, and working in a surgical ICU were positively associated with greater stress levels. Increasing age and married status were negatively associated with stress. Intensive care unit type (semi-closed vs open), ICU bed number, shift time, working on holidays, education level, and demographic factors including body mass index, and number of children were not significantly associated with stress levels. As the largest study of its kind, these findings support those found in various European, North, and South American studies. Efforts to decrease workplace stress of ICU nurses by focusing on facilitating peer collaboration, improving resource availability, and staffing ratios are likely to show the greatest impact on stress levels.

Findings from the National Criminal Justice Drug Abuse Treatment Studies (CJ-DATS) National Criminal Justice Treatment Practices survey are examined to describe types of services provided by three types of prisons: those that serve a cross-section of offenders, those that specialize in serving offenders with special psychosocial and medical needs, and those that specialize in serving legal status or gender specific populations. Information is presented on the prevalence and type of specialized prisons and services provided to offenders as reported by wardens and other facility directors drawn from a nationally representative sample of prisons. Additional analyses explore organizational factors that differentiate prisons that serve specialized populations including staffing, training, other resources, leadership, and climate for change and innovation. Implications for expanding and improving services for special populations in correctional settings and the values of specialized prisons are discussed. PMID:18443650

Almost half of the patients with gout are not prescribed urate-lowering therapy (ULT) by their health care provider and >50 % use complementary and alternative therapies. Diet modification is popular among gout patients due to known associations of certain foods with gout flares. The interplay of the use of dietary supplements, diet modification, and ULT adherence in gout patients is not known. Despite the recent interest in diet and supplements, there are limited data on their use. Our objective was to assess ULT use and adherence and patient preference for non-pharmacological interventions by patients with gout, using a cross-sectional survey. People who self-reported physician-diagnosed gout during their visit to a gout website ( http://gouteducation.org ) were invited to participate in a brief anonymous cross-sectional Internet survey between 08/11/2014 to 04/14/2015 about the management of their gout. The survey queried ULT prescription, ULT adherence, the use of non-pharmacological interventions (cherry extract, diet modification) and the likelihood of making a lifelong diet modification for gout management. A total of 499 respondents with a mean age 56.3 years were included; 74% were males and 74% were White. Of these, 57% (285/499) participants were prescribed a ULT for gout, of whom 88% (251/285) were currently taking ULT. Of those using ULT, 78% (97/251) reported ULT adherence >80%. Gender, race, and age were not significantly associated with the likelihood of receiving a ULT prescription or ULT adherence >80%. Fifty-six percent of patients with gout preferred ULT as a lifelong treatment for gout, 24% preferred cherry extract and 16% preferred diet modification (4% preferred none). Men had significantly lower odds of preferring ULT as the lifelong treatment choice for gout vs. other choices (p = 0.03). We found that 38.3% participants were highly motivated to make a lifelong dietary modification to improve their gout (score of 9-10 on a 0

Objective To detect any change in exposure to secondhand smoke among primary schoolchildren after implementation of smoke-free legislation in Scotland in March 2006. Design Comparison of nationally representative, cross sectional, class based surveys carried out in the same schools before and after legislation. Setting Scotland. Participants 2559 primary schoolchildren (primary 7; mean age 11.4 years) surveyed in January 2006 (before smoke-free legislation) and 2424 in January 2007 (after legislation). Outcome measures Salivary cotinine concentrations, reports of parental smoking, and exposure to tobacco smoke in public and private places before and after legislation. Results The geometric mean salivary cotinine concentration in non-smoking children fell from 0.36 (95% confidence interval 0.32 to 0.40) ng/ml to 0.22 (0.19 to 0.25) ng/ml after the introduction of smoke-free legislation in Scotland—a 39% reduction. The extent of the fall in cotinine concentration varied according to the number of parent figures in the home who smoked but was statistically significant only among pupils living in households in which neither parent figure smoked (51% fall, from 0.14 (0.13 to 0.16) ng/ml to 0.07 (0.06 to 0.08) ng/ml) and among pupils living in households in which only the father figure smoked (44% fall, from 0.57 (0.47 to 0.70) ng/ml to 0.32 (0.25 to 0.42) ng/ml). Little change occurred in reported exposure to secondhand smoke in pupils' own homes or in cars, but a small decrease in exposure in other people's homes was reported. Pupils reported lower exposure in cafes and restaurants and in public transport after legislation. Conclusions The Scottish smoke-free legislation has reduced exposure to secondhand smoke among young people in Scotland, particularly among groups with lower exposure in the home. We found no evidence of increased secondhand smoke exposure in young people associated with displacement of parental smoking into the home. The Scottish smoke

Low iodine intake during pregnancy may cause thyroid dysfunction, which results in inadequate fetal brain development. In the absence of a universal salt iodization programme, we conducted a nationwide survey of iodine deficiency in pregnant women in Latvia. A countrywide twenty-cluster survey, with at least twenty women per cluster. Participants completed a questionnaire on dietary habits concerning iodine intake (n 739). Thyroid function (thyroid-stimulating hormone, free thyroxine and thyroperoxidase antibodies) was measured (n 550). Urinary iodine was measured using the ammonium persulfate method (n 696). The survey was performed in all regions of Latvia during the spring and autumn seasons in 2013. Pregnant women (n 829). The median creatinine (Cr)-standardized urinary iodine concentration (UIC) was 80·8 (interquartile range (IQR) 46·1-130·6) µg/g Cr or 69·4 (IQR 53·9-92·6) µg/l during pregnancy, and 81% of pregnant women had UIC levels below the WHO recommended range of 150-250 µg/g Cr. The UIC was lowest during the first trimester of pregnancy, 56·0 (IQR 36·4-100·6) µg/g Cr, reaching higher concentrations of 87·5 (IQR 46·4-141·7) µg/g Cr and 86·9 (IQR 53·8-140·6) µg/g Cr in the second and third trimesters, respectively. Women taking supplements containing ≥150 µg iodine (6·8% of respondents) had non-significantly higher UIC than did women without supplementation (96·2 v. 80·3 µg/g Cr, respectively, P=NS). Thyroperoxidase antibody concentration did not correlate significantly with UIC: Spearman's ρ=-0·012, P=0·78. The median UIC indicates iodine deficiency in pregnant women in Latvia. Iodine supplementation (150 µg daily) and regular UIC monitoring should be suggested to overcome iodine deficiency and to reach the recommended levels without inducing autoimmune processes.

To describe the credentialing systems of North American emergency department systems (EDS) with emergency ultrasound (EUS) fellowship programmes. This is a prospective, cross-sectional, survey-based study of North American EUS fellowships using a 62-item, pilot-tested, web-based survey instrument assessing credentialing and training systems. The American College of Emergency Physicians (ACEP) distributed the surveys using SNAP survey (Snap Surveys Ltd, Portsmouth, New Hampshire, USA). Over 6 months, 75 eligible programmes were surveyed, 55 responded (73% response rate); 1 declined to participate leaving 54 participating programmes. Less than 20% of EDS credential nurses, physician assistants, nurse practitioners and students in EUS. Respondent EDS reported having an average of 4.2 ± 3.3 ultrasound faculty members (faculty identifying their career focus as EUS). The median number of annual point-of-care ultrasounds reported was 5000 (IQR 3000-8000). 30 EDS (56%) credential each examination individually and 48 EDS (89%) use ACEP credentialing criteria. 61% of fellowship leadership believe their credentialing system is either satisfactory or very satisfactory (Cronbach's coefficient α=0.84). The data show heterogeneity among North American EDS with EUS fellowship programmes with regard to credentialing systems despite published guidelines from the ACEP and Canadian Emergency Ultrasound Society.

Drug use is becoming normalised among young Australian people involved in music sub-cultures. We aimed to determine prevalences of illicit drug use in this population and associations between preferences for different music genres and recent use of particular illicit drugs. A cross-sectional questionnaire of young people (aged 16-29 years) attending a music festival. Of 939 respondents, 46% had used illicit drugs (principally cannabis) in the past month, a significantly higher proportion than among respondents to the 2004 National Drug Strategy Household Survey (18%). Participants who favoured dance/house or rap music were more likely to have used illicit drugs recently than the remainder of the sample, while those who favoured pop or alternative music were less likely to have used drugs in the past month. These data suggest that music festival attendees use illicit drugs more commonly than their age-matched cohort in the general community, and that music festivals venues (particularly those that cater for dance/house and rap) would be appropriate places for interventions to promote safer drug use.

Objectives This study aimed to explore variations in the provision of integrated academic surgical training across the UK. Design This is an online cross-sectional survey (consisting of 44 items with a range of free-text, binomial and 5-point Likert scale responses) developed by the Association of Surgeons in Training. Setting A self-reported survey instrument was distributed to academic surgical trainees across the UK (n=276). Participants 143 (51.9%) responses were received (81% male, median age: 34 years), spanning all UK regions and surgical specialties. Of the 143 trainees, 29 were core trainees (20.3%), 99 were specialty trainees (69.2%) and 15 (10.5%) described themselves as research fellows. Results The structure of academic training varied considerably, with under a third of trainees receiving guaranteed protected time for research. Despite this, however, 53.1% of the respondents reported to be satisfied with how their academic training was organised. Covering clinical duties during academic time occurred commonly (72.7%). Although most trainees (n=88, 61.5%) met with their academic supervisor at least once a month, six (4.2%) never had an academic supervisory meeting. Most trainees (n=90, 62.9%) occupied a full-time rota slot and only 9.1% (n=13) described their role as ‘supernumerary’. Although 58.7% (n=84) of the trainees were satisfied with their clinical competence, 37.8% (n=54) felt that clinical time focused more on service provision than the acquisition of technical skills. 58 (40.6%) had experienced some form of negative sentiment relating to their status as an academic trainee. Conclusions Integrated academic training presents unique challenges and opportunities within surgery. This survey has identified variation in the quality of current programmes, meaning that the future provision of integrated surgical academic training should be carefully considered. PMID:28408726

Mental health literacy in korean older adults: A cross-sectional survey.

PubMed

Kim, Y S; Lee, H Y; Lee, M H; Simms, T; Park, B H

2017-09-01

WHAT IS KNOWN ON THE SUBJECT?: Mental health literacy is a fairly new concept, first introduced in 1997. It refers to what people know and believe about mental health disorders. People's knowledge and beliefs help them to recognize, manage and prevent mental disorders. Generally, older adults have lower health literacy compared to young and middle-aged adults. WHAT THIS STUDY ADDS TO EXISTING KNOWLEDGE?: This is the first study on the mental health literacy of Korean older adults. This study looks beyond peoples' ability to recognize mental health disorders and their opinions about them. It identifies factors that are associated with mental health literacy (level of education and social support, the number of people in one's social circles and how individuals rate their health). WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Older adults might get more out of mental health literacy programmes in group or social settings. Programmes that use older adult peer educators/supporters, such as the "older people's champions" of the Healthy Passport programme in England, might make the programmes more effective. Mental health campaigns, such as Australia's beyondblue, might increase mental health literacy of older adults. Introduction Korea is experiencing rapid population ageing, spurring an increased need for mental health services for the elderly. Approximately one-third of Korean older adults experience depressive symptoms, and Korea has the highest elder suicide rate among 34 developed nations. Mental health literacy is an important component of promoting mental health, yet studies on the concept have been conducted in few countries. Aim This study examines the level of mental health literacy among Korean older adults and identifies factors associated with their mental health literacy. Method A cross-sectional survey was conducted with 596 community-dwelling Korean adults aged 65 and older. Andersen's Behavioral Model of Health Services Use framed the study. Results Overall

Current estimates suggest that 15% of all prisoners worldwide are chronically infected with the hepatitis C virus (HCV), and this number is even higher in regions with high rates of injecting drug use. Although harm reduction services such as opioid substitution therapy (OST) and needle and syringe programs (NSPs) are effective in preventing the further spread of HCV and HIV, the extent to which these are available in prisons varies significantly across countries. The Hep-CORE study surveyed liver patient groups from 25 European countries in 2016 and mid-2017 on national policies related to harm reduction, testing/screening, and treatment for HCV in prison settings. Results from the cross-sectional survey were compared to the data from available reports and the peer-reviewed literature to determine the overall degree to which European countries implement evidence-based HCV recommendations in prison settings. Patient groups in nine countries (36%) identified prisoners as a high-risk population target for HCV testing/screening. Twenty-one countries (84%) provide HCV treatment in prisons. However, the extent of coverage of these treatment programs varies widely. Two countries (8%) have NSPs officially available in prisons in all parts of the country. Eleven countries (44%) provide OST in prisons in all parts of the country without additional requirements. Despite the existence of evidence-based recommendations, infectious disease prevention measures such as harm reduction programs are inadequate in European prison settings. Harm reduction, HCV testing/screening, and treatment should be scaled up in prison settings in order to progress towards eliminating HCV as a public health threat.

This study examined the extent to which sporting event attendance is associated with self-rated health. Drawing from an economic model of health production and psychological research on the health benefits of psychosocial resources, sporting event attendance was hypothesized to have a positive relationship with self-rated health. A two-level multilevel ordered logistic regression was used to analyze multiyear cross-sectional data collected from national surveys in Japan. The results demonstrate that, controlling for the effects of personal and environmental characteristics, sporting event attendance positively correlates with self-rated health over a 12-year period. Specifically, when compared to individuals who did not attend any sporting event during the past year, those who attended a sporting event were 33% more likely to indicate a higher level of self-rated health. These findings provide evidence for a positive association between sport spectatorship and the perception of general health and contribute to the literature examining the relationship between sport spectatorship and health outcomes.

To assess community pharmacists' knowledge of human immunodeficiency virus (HIV), antiretroviral therapy, and new in-home oral fluid HIV test. A cross-sectional questionnaire administered to pharmacists, student pharmacists, and technicians before an education program at the New Mexico Pharmacists Association 2013 Mid-Winter Meeting in Albuquerque, NM. The main outcome measure was community pharmacists' correct response rate of 75% or more. Overall survey response rate of attendees was 89% (173/194 attendees). Among them 87 participants were community pharmacists; 87% of community pharmacists responded correctly when asked how HIV antiretroviral medications work and 84.3% correctly identified known sources of HIV infection. The 75% predefined adequate knowledge threshold was not met on any HIV screening or in-home HIV test knowledge items. Only 65.1% of community pharmacists correctly identified the minimum number of antiretroviral drugs that should be included in an ideal HIV treatment regimen. The only variable that positively influenced pharmacists' knowledge was age. An inverse relationship between pharmacist age and HIV knowledge was observed among study participants. Community pharmacists from urban and rural areas in New Mexico possessed adequate basic HIV knowledge, but did not demonstrate adequate HIV screening or in-home HIV test knowledge. Future educational interventions aimed at improving pharmacist knowledge in this area are warranted.

Physician staffing is an important determinant of patient outcomes following intensive care unit (ICU) admission. We conducted a national survey of in-house after-hours physician staffing in Canadian ICUs. : Cross-sectional survey. Canadian adult and pediatric ICUs. ICU directors. ICU directors of Canadian adult and pediatric ICUs were surveyed to describe overnight staffing by interns, residents, critical care medicine trainees, clinical assistants, and ICU physicians in their ICUs. Data were collected regarding hospital and ICU demographics and ICU staffing. For ICUs with in-house overnight physicians, we documented physician experience, shift duration, and clinical responsibilities outside the ICU. We identified 98 Canadian ICU directors, of whom 88 (90%) responded. Dedicated in-house physician coverage overnight was reported in 53 (60%) ICUs, including 13 (15%) in which ICU staff physicians stayed in-house overnight. Compared with ICUs without in-house physicians, those with in-house physicians had more ICU beds (15 vs. 8.5, p=.0001) and fewer ICU staff physicians (5 vs. 7, p=.03). For the 271 physicians who provide overnight staffing, the median level of postgraduate experience was 3 yrs (range, <1 yr, >10 yrs); 129 (48%) had <3 months of ICU experience. Most shifts (83%) were >20 hrs long. In-house overnight physician staffing in Canadian ICUs varies widely. Only a minority of ICUs comply with the 2003 Society of Critical Care Medicine guidelines for adult ICUs recommending continuous in-house staffing by ICU staff physicians. The duration of most ICU shifts raises concern about workload-associated fatigue and medical error. The impact of current nighttime staffing requires further evaluation with respect to patient outcomes.

Aim To assess the reasons for low influenza vaccination coverage in Poland, including knowledge of influenza and attitudes toward influenza vaccination. Methods This was a cross-sectional, anonymous, self-administered survey in primary care patients in Lodzkie voivodship (central Poland). The study participants were adults who visited their primary care physicians for various reasons from January 1 to April 30, 2007. Results Six hundred and forty participants completed the survey. In 12 months before the study, 20.8% participants had received influenza vaccination. The most common reasons listed by those who had not been vaccinated were good health (27.6%), lack of trust in vaccination effectiveness (16.8%), and the cost of vaccination (9.7%). The most common source of information about influenza vaccination were primary care physicians (46.6%). Despite reasonably good knowledge of influenza, as many as approximately 20% of participants could not point out any differences between influenza and other viral respiratory tract infections. Conclusions The main reasons for low influenza vaccination coverage in Poland were patients’ misconceptions and the cost of vaccination. Therefore, free-of-charge vaccination and more effective informational campaigns are needed, with special focus on high-risk groups. PMID:21495194

The purpose of this study was to describe patient characteristics and summarize their perceptions of chiropractic in Australia. This study is part of a broader study aiming to extend the knowledge of the role of chiropractic within the current health care environment. A 33-item, paper-based, cross-sectional survey of a sample of patients from 100 systematically sampled chiropractic clinics from all the states and territories of Australia was conducted. The survey focused on patient demographics, socioeconomic status, perceived health status, and perceptions of chiropractic and chiropractic services. A total of 486 responses were received (24.3% response rate). Respondents were predominantly female patients (67.1%) of the 45- to 64-year age group. Approximately half of the respondents reported a pretax annual income exceeding $40000. Most patients sought chiropractic services because of musculoskeletal disorders (68.7%) and for general health (21.2%), and personal beliefs motivated most respondents (70.2%) to visit a chiropractor. Most respondents would seek the chiropractic services again (97.5%) and were satisfied with the service received. The results of this study show that the typical chiropractic patient in Australia is a middle-aged woman with a moderate to high income. Although only a small proportion of the Australian population sees a chiropractor, this group seems to be satisfied with the service. Copyright © 2014 National University of Health Sciences.

Although specific phobia is highly prevalent, associated with impairment, and an important risk factor for the development of other mental disorders, cross-national epidemiological data are scarce, especially from low- and middle-income countries. This paper presents epidemiological data from 22 low-, lower-middle-, upper-middle- and high-income countries. Data came from 25 representative population-based surveys conducted in 22 countries (2001-2011) as part of the World Health Organization World Mental Health Surveys initiative (n = 124 902). The presence of specific phobia as defined by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition was evaluated using the World Health Organization Composite International Diagnostic Interview. The cross-national lifetime and 12-month prevalence rates of specific phobia were, respectively, 7.4% and 5.5%, being higher in females (9.8 and 7.7%) than in males (4.9% and 3.3%) and higher in high- and higher-middle-income countries than in low-/lower-middle-income countries. The median age of onset was young (8 years). Of the 12-month patients, 18.7% reported severe role impairment (13.3-21.9% across income groups) and 23.1% reported any treatment (9.6-30.1% across income groups). Lifetime co-morbidity was observed in 60.5% of those with lifetime specific phobia, with the onset of specific phobia preceding the other disorder in most cases (72.6%). Interestingly, rates of impairment, treatment use and co-morbidity increased with the number of fear subtypes. Specific phobia is common and associated with impairment in a considerable percentage of cases. Importantly, specific phobia often precedes the onset of other mental disorders, making it a possible early-life indicator of psychopathology vulnerability.

OBJECTIVE. This study examined the relationship between childhood obesity and overweight and functional activity and its enjoyment. METHOD. A cross-sectional design was used to analyze data from the 2012 National Health and Nutrition Examination Survey National Youth Fitness Survey. Multivariate logistic regression models were used. RESULTS. Data for 1,640 children ages 3–15 yr were retrieved. Physical activity was negatively associated with risk of obesity (odds ratio [OR] = 0.93; 95% confidence interval [CI] [0.87, 0.98]). Although children who were obese and overweight were more likely to have functional limitations (ORs = 1.58–1.61), their enjoyment of physical activity participation was not significantly different from that of the healthy-weight group. CONCLUSION. Physical activity lowered the risk of obesity. Children who were obese had functional limitations compared with healthy-weight children, but both groups enjoyed physical activity equally. Future studies are needed to determine barriers to participation among these children in recreation and sporting activities. PMID:27548862

Objectives: This study examined the patterns and determinants of current smoking and intention to smoke among secondary school students of Han and Tujia nationalities in China. Methods: A cross-sectional survey was conducted in three regions, namely, Chongqing, Liaocheng, and Tianjin, of China in 2015. A structured self-administered questionnaire was used for data collection. Results: Of the total subjects (n = 1805), 78.9% were ethnic Han and 21.1% were ethnic Tujia. Overall 9.4% (Han: 7.7%; Tujia: 15.5%) secondary school students were smokers and 37.28% smoked more than once per day. Of the non-smoker students (n = 1636), 17.4% have an intention to smoke. A total of 81.1% of students reportedly had never been taught throughout school about smoking or tobacco prevention. When compared to the students who were taught in the school about smoking or tobacco prevention (18.90%) students who were never taught were more likely to smoke (OR = 2.39; 95% CI = 1.14–5.01). As compared to Han nationality students who were from Tujia nationality were more likely to smoke (OR = 2.76; 95% CI = 1.88–4.04) and were more likely to have a higher frequency of smoking (95% CI (0.88, 0.88), p = 0.010). Non-smokers who were high school students (OR = 4.29; 95% CI = 2.12–8.66), whose academic performance were situated in the last 25% (OR = 2.23; 95% CI = 1.48–3.34) and lower than 50% (OR = 1.50; 95% CI = 1.02–2.20) were more likely to have an intention of smoking. Conclusions: About one in ten secondary school students was a smoker, one in three smokers smoked more than one time per day, and a quarter of non-smokers had an intention of smoking in China. Smoking rate was higher among students from Tujia than the Han nationality. This study provided some important information for future tobacco control programs among secondary school students in the ethnic minority autonomous region and minority settlements in a multi-ethnic country.

To investigate associations between active transport, employment status and objectively measured moderate-to-vigorous physical activity (MVPA) in a representative sample of US adults. Cross-sectional analyses of data from the National Health and Nutrition Examination Survey. A total of 5180 adults (50.2 years old, 49.0% men) were classified by levels of active transportation and employment status. Outcome measure was weekly time spent in MVPA as recorded by the Actigraph accelerometer. Associations between active transport, employment status and objectively measured MVPA were examined using multivariable linear regression models adjusted for age, body mass index, race and ethnicity, education level, marital status, smoking status, working hour duration (among the employed only) and self-reported leisure time physical activity. Patterns of active transport were similar between the employed (n=2897) and unemployed (n=2283), such that 76.0% employed and 77.5% unemployed engaged in no active transport. For employed adults, those engaging in high levels of active transport (≥90 min/week) had higher amount of MVPA than those who did not engage in active transport. This translated to 40.8 (95% CI 15.7 to 65.9) additional minutes MVPA per week in men and 57.9 (95% CI 32.1 to 83.7) additional minutes MVPA per week in women. Among the unemployed adults, higher levels of active transport were associated with more MVPA among men (44.8 min/week MVPA, 95% CI 9.2 to 80.5) only. Findings from the present study support interventions to promote active transport to increase population level physical activity. Additional strategies are likely required to promote physical activity among unemployed women. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Introduction The effect on behavioral change of educational programs developed to reduce the community's disaster informational vulnerability is not known. This study describes the relationship of disaster education, age, sex, and country-specific characteristics with students discussing disasters with friends and family, a measure of proactive behavioral change in disaster preparedness. Three thousand eight hundred twenty-nine final year high school students were enrolled in an international, multi-center prospective, cross-sectional study using a pre-validated written questionnaire. In order to obtain information from different educational systems, from countries with different risk of exposure to disasters, and from countries with varied economic development status, students from Bahrain, Croatia, Cyprus, Egypt, Greece, Italy, Portugal, Romania, and Timor-Leste were surveyed. Logistic regression analyses examined the relationship between the likelihood of discussing disasters with friends and family (dependent variable) and a series of independent variables (age, gender, participation in school lessons about disasters, existence of a national disaster educational program, ability to list pertinent example of disasters, country's economic group, and disaster risk index) captured by the questionnaire or available as published data. There was no statistically significant relationship between age, awareness of one's surroundings, planning for the future, and foreseeing consequences of events with discussions about potential hazards and risks with friends and/or family. The national educational budget did not have a statistically significant influence. Participants who lived in a low disaster risk and high income Organization for Economic Co-operation and Development (OECD) country were more likely to discuss disasters. While either school lessons or a national disaster education program had a unique, significant contribution to the model, neither had a better

Cross-National Trends in Religious Service Attendance

Brenner, Philip S.

2016-01-01

The nature of religious change and the future of religion have been central questions of social science since its inception. But empirical research on this question has been quite American-centric, encouraged by the conventional wisdom that the United States is an outlier of religiosity in the developed world, and, more pragmatically, by the availability of survey data. The dramatic growth in the number and reach of cross-national surveys over the past two decades has offered a corrective. These data have allowed research on religious trends in the United States, Canada, and Europe, putting American trends into comparative relief. This research synthesis reviews the past quarter century of cross-national comparative survey research on religious behavior, focusing on religious service attendance as a commonly measured behavior that is arguably more equivalent across societies and cultures than other measures of religiosity. The lack of evidence for religious revival is highlighted, noting instead declining rates of attendance in the United States and Canada, and either declining rates or low “bottomed-out” stability in Western Europe, most of Eastern Europe, and Australia and New Zealand. Finally, countries in Latin America, Africa, and Asia are discussed to the extent that research allows, before a call for future research—in these places in particular—is made in order to correct for the Western and Christian focus of much of the research on cross-national religious trends.

To investigate the change in the prevalence of dental erosion, over time, by a review of the data from the published national dental surveys of young people in the UK. A subsidiary objective was to investigate the relationship between erosion and possible associated risk factors. The review was based on cross-sectional prevalence studies incorporating a clinical dental examination and structured interviews. The data were collated from the 1993 UK childrens' dental health survey and the dental report of the two National Diet and Nutrition Surveys (NDNS) of children aged 1(1/2)-4(1/2) in 1992/3 and 4-18 years in 1996/7. The criteria used for data collection were comparable between the three different studies. Comparing the data from the different studies, the prevalence of erosion was seen to increase from the time of the childrens' dental health survey in 1993 and the NDNS study of 4-18-year-olds in 1996/7. There was a trend towards a higher prevalence of erosion in children aged between 3(1/2) and 4(1/2) and in those who consumed carbonated drinks on most days compared with toddlers consuming these drinks less often. Drinks overnight were associated with an increased prevalence of erosion. More 4-6-year-olds with reported symptoms of gastro-oesophageal reflux had erosion compared with symptom-free children. On multivariate analysis, the strongest independent association with erosion was geography, with children living in the North having twice the odds of having erosion compared with those in London and the South-east. Comparing prevalence data from cross-sectional national studies indicates that dental erosion increases between different age cohorts of young people over time. Dietary associations with erosion are present but weak. Similarly, there is an association apparent between erosion, symptoms of gastro-oesophageal reflux and socio-demographic variables such as region of domicile, social class, and receipt of social benefits.

Objectives To examine whether patient satisfaction with nursing care in National Health Service (NHS) hospitals in England is associated with the proportion of non-UK educated nurses providing care. Design Cross-sectional analysis using data from the 2010 NHS Adult Inpatient Survey merged with data from nurse and hospital administrator surveys. Logistic regression models with corrections for clustering were used to determine whether the proportions of non-UK educated nurses were significantly related to patient satisfaction before and after taking account of other hospital, nursing and patient characteristics. Setting 31 English NHS trusts. Participants 12 506 patients 16 years of age and older with at least one overnight stay that completed a satisfaction survey; 2962 bedside care nurses who completed a nurse survey; and 31 NHS trusts. Main outcome measure Patient satisfaction. Results The percentage of non-UK educated nurses providing bedside hospital care, which ranged from 1% to 52% of nurses, was significantly associated with patient satisfaction. After controlling for potential confounding factors, each 10-point increase in the percentage of non-UK educated nurses diminished the odds of patients reporting good or excellent care by 12% (OR=0.88), and decreased the odds of patients agreeing that they always had confidence and trust in nurses by 13% (OR=0.87). Other indicators of patient satisfaction also revealed lower satisfaction in hospitals with higher percentages of non-UK educated nurses. Conclusions Use of non-UK educated nurses in English NHS hospitals is associated with lower patient satisfaction. Importing nurses from abroad to substitute for domestically educated nurses may negatively impact quality of care. PMID:26634400

2016-12-01

The Bhutan National Pharmacovigilance Centre (NPC) became an official member of the WHO Programme for International Drug Monitoring in December 2014; however, the number of adverse drug reactions (ADRs) reported is very low (50 reports per 773,722 inhabitants over 10 years). Surveys of healthcare professionals (HCPs) in similar countries have indicated that adequate knowledge of both ADRs and ADR reporting is likely to increase the number of ADR reports submitted. The aim of this study was to investigate the level of knowledge of both ADRs and ADR reporting among HCPs, including traditional medicine practitioners. A cross-sectional survey was conducted, using a validated self-administered questionnaire. The questionnaires were distributed to 670 HCPs, including clinical doctors, nurses, pharmacists and traditional medicine practitioners from four referral hospitals. The survey consisted of 12 questions pertaining to ADRs and 10 questions pertaining to knowledge of ADR reporting. The collected response was then analysed descriptively and results presented as mean ± standard deviation (SD) using SPSS version 20. The overall response rate was 434 (65 %) questionnaires, with HCPs consisting of clinical doctors (94, 22 %), nurses (257, 59 %), pharmacists (52, 12 %) and traditional medicine practitioners (31, 7 %). The overall mean ± SD score with regard to the level of knowledge of ADRs was 6.52 ± 2.81 out of a maximum score of 12, among which clinical doctors scored 7.48 ± 2.95, nurses 6.15 ± 2.47, pharmacists 8.15 ± 2.49 and traditional medicine practitioners 4.13 ± 3.18. The mean ± SD score with regard to the level of knowledge of ADR reporting among HCPs was 3.94 ± 1.89 out of a maximum score of 10, among which clinical doctors scored 3.93 ± 1.81, nurses 3.75 ± 1.74, pharmacists 5.00 ± 1.81 and traditional medicine practitioners 4.00 ± 1.77. Clinical doctors and pharmacists have better knowledge of ADRs than nurses and

A national survey was conducted to measure and benchmark women's experiences with pregnancy, birth and postnatal care in Norway. The purpose of this secondary analysis is to explore potential variation in these experiences with regard to the survey respondents' geographic origin. Data were collected in a national observational cross-sectional study, by a self-administered questionnaire and from registries. The questionnaire collects patient reported experience measures (PREMS) of mainly nontechnical aspects of the health-care services. While taking the clustered characteristics of the respondents into consideration, we compared the mean scores on 16 indexes between women of four different geographic origins using linear regression models. The origin of the 4904 respondents were classified as Norway (n = 4028, 82%), Western Europe, North-America, Oceania (n = 233, 5%), Eastern Europe (n = 290, 6%), and Asia, Turkey, Africa, and South-America) (n = 353, 7%). The observed differences were moderate, and no consistency was present in the results in respect of direction or magnitude of the differences between the groups. With some important cautions, we conclude that this study did not detect systematic differences between groups of different geographic origin, in their experiences with pregnancy and maternity care in Norway.

Background The negative impact of work has been the traditional focus of GP surveys. We know little about GP positive mental health and psychological resources. Aim To profile and contextualise GP positive mental health and personal psychological resources. Design and setting Cross-sectional survey of GPs working in Northern Ireland (NI). Method A questionnaire comprising the Warwick Edinburgh Mental Wellbeing Scale (WEMWBS) and measures of resilience, optimism, self-efficacy, and hope, and sociodemographic information was posted to 400 GPs randomly selected from a publicly available GP register. Results The response rate was 55% (n = 221 out of 400). Mean value for GP wellbeing (WEMWBS) was 50.2 (standard deviation [SD] 8) compared to UK vets 48.8 (SD 9), UK teachers 47.2 (SD 9), and the population of NI 50.8 (SD 9). After adjustment for confounding, mean WEMWBS was 2.4 units (95% CI = 0.02 to 4.7) higher in female GPs than males (P = 0.05), and 4.0 units (95% CI = 0.8 to 7.3) higher in GPs ≥55 years than GPs ≤44 years (P = 0.02). Optimism was 1.1 units higher in female GPs than male GPs (95% CI = 0.1 to 2.0), and 1.56 units higher in GPs ≥55 years (95% CI = 0.2 to 2.9) than in those ≤44 years. Hope was 3 units higher in GPs ≥55 years (95% CI = 0.4 to 5.7) than in those aged 45–54 years. Correlation between WEMWBS and psychological resources was highest with hope (r = 0.65, P < 0.001). Conclusion GPs have levels of positive mental health that are comparable to the local population and better than other occupational groups, such as vets and teachers. Male and younger GPs may have most to gain from wellbeing interventions. PMID:28716997

Background A high prevalence of stress-related disorders is well known among healthcare professionals. We set out to assess the prevalence of cardiovascular risk factors and compliance with national dietary and physical activity recommendations in NHS staff in the UK with comparison between clinical and non-clinical staff, and national surveys. Design A multi-centre cross-sectional study. Methods A web-based questionnaire was developed to include anonymised data on demographics, job role, cardiovascular risk factors and diseases, dietary habits, physical activity and barriers towards healthy lifestyle. This was distributed to staff in four NHS hospitals via emails. Results A total of 1158 staff completed the survey (response rate 13%) with equal distribution between the clinical and non-clinical groups. Most staff were aged 26-60 years and 79% were women. Half of the staff were either overweight or obese (51%) with no difference between the groups ( P = 0.176), but there was a lower prevalence of cardiovascular risk factors compared to the general population. The survey revealed a low compliance (17%) with the recommended intake of five-a-day portions of fruit and vegetables, and that of moderate or vigorous physical activity (56%), with no difference between the clinical and non-clinical staff ( P = 0.6). However, more clinical staff were exceeding the alcohol recommendations ( P = 0.02). Lack of fitness facilities and managerial support, coupled with long working hours, were the main reported barriers to a healthy lifestyle. Conclusions In this survey of UK NHS staff, half were found to be overweight or obese with a lower prevalence of cardiovascular risk factors compared to the general population. There was a low compliance with the five-a-day fruit and vegetables recommendation and physical activity guidelines, with no difference between the clinical and non-clinical staff.

Helicopter Emergency Medical Services (HEMS) aim to bring a highly specialised crew to the scene of major incidents for triage, treatment and transport. We aim to describe experiences made by HEMS in Norway in the management of major incidents. Doctors, rescue paramedics and pilots working in Norwegian HEMS and Search and Rescue Helicopters (SAR) January 1st 2015 were invited to a cross-sectional study on experiences, preparedness and training in major incident management. We identified a total of 329 Norwegian crewmembers of which 229 (70%) responded; doctors 101/150, (67%), rescue paramedics 64/78 (82%), pilots 64/101, (63%). HEMS and SAR crewmembers had experience from a median of 2 (interquartile range 0-6) major incidents. Road traffic incidents were the most frequent mechanism and blunt trauma the dominating injury. HEMS mainly contributed with triage, treatment and transport. Communication with other emergency services prior to arrival was described as bad, but good to excellent when cooperating on scene. The respondents called for more interdisciplinary exercises. HEMS and SAR crewmembers have limited exposure to major incident management. Interdisciplinary training on frequent scenarios with focus on cooperation and communication is called for.

This study aimed to characterize the use of mandated quality indicators (QIs) in public sector nursing homes by describing their adherence to established principles of measurement and whether nursing homes respond to QI data to improve care. Data were collected from a descriptive cross-sectional quantitative study using a confidential survey questionnaire distributed electronically to senior staff in all public sector nursing homes in Victoria, Australia. Staff from 113 of 196 facilities completed the survey (58%). Adherence to principles of measurement was suboptimal, with variation in applying QI definitions and infrequent random audits of data (n = 54, 48%). QI data triggered reviews of individual residents (62%-79%), staff practice (44%-65%), and systems of care (45%-55%). Most facilities (58%-75%) reported that beneficial changes in care occurred as a result of using QIs. QI performance data are positively received and used to improve care. Standardization of data collection, analysis, and reporting should strengthen the program's utility. © The Author(s) 2014.

Organisations seeking to establish themselves as leading cancer information sources for the public need to understand patterns and motivators for information seeking. This study describes cancer information seeking among New Zealanders through a national cross-sectional survey conducted in 2014/15 with a population-based sample of adults (18 years and over). Participants were asked if they had sought information about cancer during the past 12 months, the type of information they sought, what prompted them to look for information and ways of getting information they found helpful. Telephone interviews were completed by 1064 participants (588 females, 476 males, 64% response rate). Of these, 33.8% of females and 23.3% of males (total, 29.2%) had searched for information about cancer over the past year. A search was most frequently prompted by a cancer diagnosis of a family member or friend (43.3%), a desire to educate themselves (17.5%), experience of potential symptoms or a positive screening test (9.4%), family history of cancer (8.9%) or the respondent's own cancer diagnosis (7.7%). Across the cancer control spectrum, the information sought was most commonly about treatment and survival (20.2%), symptoms/early detection (17.2%) or risk factors (14.2%), although many were general or non-specific queries (50.0%). The internet was most commonly identified as a helpful source of information (71.7%), followed by health professionals (35.8%), and reading material (e.g. books, pamphlets) (14.7%).This study provides a snapshot of cancer information seeking in New Zealand, providing valuable knowledge to help shape resource delivery to better meet the diverse needs of information seekers and address potential unmet needs, where information seeking is less prevalent.

Abstract Background Although national findings regarding people's end-of-life care (EoLC) preferences and priorities are available within Europe, a lack of research coordination between countries has meant that cross-national understandings of EoLC remain unknown. Purpose To (1) identify English and German understandings of EoLC within the context of an EoLC survey, and (2) to synthesise these understandings to aid interpretation of results from a cross-national survey. Methods An inductive and interpretive two-phased sequential design involving (1) qualitative analysis of cognitive interview data from 15 English and 15 German respondents to develop country-related categories, and (2) qualitative synthesis to identify a conceptually coherent understanding of EoLC. Results Open and axial coding resulted in six English and six German categories. Commonalities included (a) the importance of social and relational dimensions, (b) dynamic decision making comprising uncertainty, (c) a valuing of life's quality and quantity, and (d) expectations for holistic care involving autonomy, choice, and timely information from trusted professionals. Differences involved attention to practical matters, and thoughts about prolongation of life, preferred place of death, and the role of media and context. Synthesis resulted in four concepts with underlying coherence: expectations of a high standard of EoLC involving autonomy, choice, and context; evolving decision making amid anticipated change; thoughts about living and existing; and worldviews shaping EoLC preferences in real and hypothetical scenarios. Conclusion Individual and country-related diversity must be remembered when quantifying EoLC understandings. Inductive-interpretive analysis of cognitive interview data aids interpretation of survey findings. Cross-national research coordination and qualitative synthesis assists EoLC in Europe.

Complementary and alternative medicine (CAM) use has steadily increased globally over the past two decades and is increasingly playing a role in the healthcare system in the United States. CAM practice-based effectiveness research requires an understanding of the settings in which CAM practitioners provide services. This paper describes and quantifies practice environment characteristics for a cross-sectional sample of doctors of chiropractic (DCs), licensed acupuncturists (LAcs), and licensed massage therapists (LMTs) in the United States. Using a cross-sectional telephone survey of DCs (n = 32), LAcs (n = 70), and LMTs (n = 184) in the Tucson, AZ metropolitan area, we collected data about each location where practitioners work, as well as measures on practitioner and practice characteristics including: patient volume, number of locations where practitioners worked, CAM practitioner types working at each location, and business models of practice. The majority of practitioners reported having one practice location (93.8% of DCs, 80% of LAcs and 59.8% of LMTs) where they treat patients. Patient volume/week was related to practitioner type; DCs saw 83.13 (SD = 49.29) patients/week, LAcs saw 22.29 (SD = 16.88) patients/week, and LMTs saw 14.21 (SD =10.25) patients per week. Practitioners completed surveys for N = 388 practice locations. Many CAM practices were found to be multidisciplinary and/or have more than one practitioner: 9/35 (25.7%) chiropractic practices, 24/87 (27.6%) acupuncture practices, and 141/266 (53.0%) massage practices. Practice business models across CAM practitioner types were heterogeneous, e.g. sole proprietor, employee, partner, and independent contractor. CAM practices vary across and within disciplines in ways that can significantly impact design and implementation of practice-based research. CAM research and intervention programs need to be mindful of the heterogeneity of CAM practices in order to create appropriate interventions, study

Wealth-related inequality across the South African antenatal HIV care cascade has not been considered in detail as a potential hindrance to eliminating mother-to-child HIV transmission (EMTCT). We aimed to measure wealth-related inequality in early (before enrolling into antenatal care) uptake of HIV testing and identify the contributing determinants. Cross-sectional survey. South African primary public health facilities in 2012. A national-level sample of 8618 pregnant women. Wealth-related inequality in early uptake of HIV testing was measured using the Erreygers concentration index (CI) further adjusted for inequality introduced by predicted healthcare need (ie, need-standardised). Determinants contributing to the observed inequality were identified using the Erreygers and Wagstaff decomposition methods. Participants were aged 13 to 49 years. Antenatal HIV prevalence was 33.2%, of which 43.7% came from the lowest 40% wealth group. A pro-poor wealth-related inequality in early HIV testing was observed. The need-standardised concentration index was -0.030 (95% confidence interval -0.038 to -0.022). The proportion of early HIV testing was significantly better in the lower 40% wealth group compared with the higher 40% wealth group (p value=0.040). The largest contributions to the observed inequality were from underlying inequalities in province (contribution, 65.27%), age (-44.38%), wealth group (24.73%) and transport means (21.61%). Our results on better early uptake of HIV testing among the poorer subpopulation compared with the richer highlights inequity in uptake of HIV testing in South Africa. This socioeconomic difference could contribute to fast-tracking EMTCT given the high HIV prevalence among the lower wealth group. The high contribution of provinces and age to inequality highlights the need to shift from reliance on national-level estimates alone but identify subregional-specific and age-specific bottlenecks. Future interventions need to be context

Smartphones and their apps are used ubiquitously in medical practice. However, in some cases their use can be at odds with current patient data safety regulations such as Canada's Personal Health Information Protection Act of 2004. To assess current practices and inform mobile application development, we sought to better understand mobile device usage patterns among Canadian neurosurgery residents. Through the Canadian Neurosurgery Research Collaborative, an online survey characterizing smartphone ownership and usage patterns was developed and sent to all Canadian neurosurgery resident in April of 2016. Questionnaires were collected and completed surveys analyzed. Of 146 eligible residents, 76 returned completed surveys (52% response rate). Of these 99% of respondents owned a smartphone, with 79% running on Apple's iOS. Four general mobile uses were identified: 1) communication between members of the medical team, 2) decision support, 3) medical reference, and 4) documentation through medical photography. Communication and photography were areas where the most obvious breaches in the Canadian Personal Health Information Protection Act were noted, with 89% of respondents taking pictures of patients' radiologic studies and 75% exchanging them with Short Message System. Hospital policies had no impact on user behaviors. Smartphones are used daily by most neurosurgery residents. Identified usage patterns are associated with perceived gains in efficacy and challenges in privacy and data reliability. We believe creating and improving workflows that address these usage patterns has a greater potential to improve privacy than changing policies and enforcing regulations.

The purpose of this study was to determine the relationship between hormone replacement therapy (HRT) and tinnitus in South Korea using data from the Korea National Health and Nutrition Examination Surveys (KNHANES) (2010-2012). Cross-sectional analysis of a nationwide health survey. KNHANES is a nationally representative cross-sectional survey of South Korea population. Only postmenopausal women aged 19-65 years were included in the study (n=2736). Auditory function was evaluated using pure-tone audiometric testing according to established KNHANES protocols. Subjects were questioned about their experience with tinnitus. Exogenous hormone-related factors included the starting age and duration of HRT. The overall prevalence of tinnitus was 22.2% among postmenopausal women. (1) Tinnitus severity was significantly higher in women using HRT (p=0.0024) and (2) significantly lower in women who breast fed their children (p=0.0386). (3) According to logistic regression models, the longer duration of HRT was significantly associated with increasing tinnitus (OR=1.323, 95% CI 1.007 to 1.737, p=0.0441). A longer duration of HRT was associated with developing tinnitus in Korean postmenopausal women. Further experimental and epidemiological researches are needed to elucidate the causal relationship between HRT and tinnitus. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Severe malaria has a case fatality rate of 10-20 %; however, few studies have addressed the quality of severe malaria case management. This study evaluated the diagnostic and treatment practices of malaria patients admitted to inpatient health facilities (HF) in Malawi. In July-August 2012, a nationwide, cross-sectional survey of severe malaria management was conducted in 36 HFs selected with equal probability from all eligible public sector HFs in Malawi. Patient records from all admissions during October 2011 and April 2012 (low and high season, respectively) were screened for an admission diagnosis of malaria or prescription of any anti-malarial. Eligible records were stratified by age (< 5 or ≥ 5 years). A maximum of eight records was randomly selected within each age and month stratum. Severe malaria was defined by admission diagnosis or documentation of at least one sign or symptom of severe malaria. Treatment with intravenous (IV) quinine or artesunate was considered correct. Patients without documentation of severe malaria were analysed as uncomplicated malaria patients; treatment with an artemisinin-based combination therapy (ACT) or oral quinine based on malaria test results was considered correct. All analyses accounted for HF level clustering and sampling weights. The analysis included 906 records from 35 HFs. Among these, 42 % (95 % confidence interval [CI] 35-49) had a severe malaria admission diagnosis and 50 % (95 % CI 44-57) had at least one severe malaria sign or symptom documented. Severe malaria patients defined by admission diagnosis (93, 95 % CI 86-99) were more likely to be treated correctly compared to patients defined by a severe sign (82, 95 % CI 75-89) (p < 0.0001). Among uncomplicated malaria patients, 26 % (95 % CI 18-35) were correctly treated and 53 % (95 % CI 42-64) were adequately treated with IV quinine alone or in combination with an ACT or oral quinine. A majority of patients diagnosed with severe malaria

Accurate total reaction cross section models are important to achieving reliable predictions from spallation and transport codes. The latest version of the Cascade Exciton Model (CEM) as incorporated in the code CEM03.03, and the Monte Carlo N-Particle transport code (MCNP6), both developed at Los Alamos National Laboratory (LANL), each use such cross sections. Having accurate total reaction cross section models in the intermediate energy region (50 MeV to 5 GeV) is very important for different applications, including analysis of space environments, use in medical physics, and accelerator design, to name just a few. The current inverse cross sections used inmore » the preequilibrium and evaporation stages of CEM are based on the Dostrovsky et al. model, published in 1959. Better cross section models are now available. Implementing better cross section models in CEM and MCNP6 should yield improved predictions for particle spectra and total production cross sections, among other results.« less

Objective To provide an overview of beverage consumption patterns using the first nationally representative survey of dietary intake in Brazil. Design Beverage consumption data were obtained by 1-day food records in an individual dietary survey. Setting nationwide cross-sectional survey, 2008–09. Subjects nationally representative sample of individuals ≥10 years (n=34,003). Results Beverages contributed to 17.1% of total energy consumption. Caloric coffee beverages provided the greatest level of energy overall (464 kJ or 111 kcal/d). Individuals from 10 to 18 (243 kJ or 58 kcal/d) and from 19 to 39 years old (230 kJ or 55 kcal/d consumed higher proportion of energy from sugar sweetened soft drinks than individuals over this age (142 kJ or 34 kcal/d for those 40–59 and 79 kJ or 19 kcal/d for those >60 years old). Conclusions Overall, the contribution of beverages, particularly sugary beverages, to total energy consumption in Brazil represents an important public health challenge and is comparable with those from other countries.

This study explored current demographics, characteristics, costs, evaluation methods, and outcome measures used in Australian cardiac rehabilitation (CR) programs. It also determined the actual usage and perceptions of high-intensity interval training (HIIT). A cross-sectional observational web-based survey was distributed to 328 Australian CR programs nationally. A total of 261 programs completed the survey (79.6% response rate). Most Australian CR programs were located in a hospital setting (76%), offered exercise sessions once a week (52%) for 6-8 weeks (49%) at moderate intensity (54%) for 46-60 min (62%), and serviced 101-500 clients per annum (38%). HIIT was reported in only 1% of programs, and 27% of respondents believed that it was safe while 42% of respondents were unsure. Lack of staff (25%), monitoring resources (20%), and staff knowledge (18%) were the most commonly reported barriers to the implementation of HIIT. Overall, Australian CR coordinators are unsure of the cost of exercise sessions. There is variability in CR delivery across Australia. Only half of programs reassess outcome measures postintervention, and cost of exercise sessions is unknown. Although HIIT is recommended in international CR guidelines, it is essentially not being used in Australia and clinicians are unsure as to the safety of HIIT. Lack of resources and staff knowledge were perceived as the biggest barriers to HIIT implementation, and there are inconsistent perceptions of prescreening and monitoring requirements. This study highlights the need to educate health professionals about the benefits and safety of HIIT to improve its usage and patient outcomes.

To characterize the existing national and multi-national registries and cohort studies in juvenile idiopathic arthritis (JIA) and identify differences as well as areas of potential future collaboration. We surveyed investigators from North America, Europe, and Australia about existing JIA cohort studies and registries. We excluded cross-sectional studies. We captured information about study design, duration, location, inclusion criteria, data elements and collection methods. We received survey results from 18 studies, including 11 national and 7 multi-national studies representing 37 countries in total. Study designs included inception cohorts, prevalent disease cohorts, and new treatment cohorts (several of which contribute to pharmacosurveillance activities). Despite numerous differences, the data elements collected across the studies was quite similar, with most studies collecting at least 5 of the 6 American College of Rheumatology core set variables and the data needed to calculate the 3-variable clinical juvenile disease activity score. Most studies were collecting medication initiation and discontinuation dates and were attempting to capture serious adverse events. There is a wide-range of large, ongoing JIA registries and cohort studies around the world. Our survey results indicate significant potential for future collaborative work using data from different studies and both combined and comparative analyses.

Since the introduction of orthodontic therapists (OTs), there has been little research on the scope of practice and the level of supervision they receive. This study investigates how OTs are being utilised and supervised, and how this compares with current recommendations. A postal cross-sectional survey was mailed to all UK General Dental Council (GDC) registered specialist orthodontists. A 59.7% response rate (747) was achieved. 52% of the respondents reported they worked with/employed an OT. The majority of orthodontists worked with an OT in primary care (67%) seeing predominantly NHS (56%) patients and performed a wide range of duties. Orthodontists reported a perceived increase in clinical output (74%) and time available for treatment planning (61%). The majority (85%) of orthodontists indicated they provide a written prescription for the OT. Forty-two per cent reported the prescription did not contain the required information as stipulated by the GDC. OTs are valued members of the orthodontic team, improving productivity and allowing orthodontists more time for treatment planning. The majority of orthodontists appeared to be working to the BOS and GDC recommendations, with greater awareness needed regarding the provision of a written treatment prescription.

Although the concern about coffee-associated health problems is increasing, the effect of coffee on osteoporosis is still conflicting. This study aimed to determine the relationship between coffee consumption and bone health in Korean postmenopausal women. A population-based, cross-sectional study was performed using a nationally representative sample of the Korean general population. All 4,066 postmenopausal women (mean age 62.6 years) from the fourth and fifth Korean National Health and Nutrition Examination Survey (2008-2011), who completed the questionnaire about coffee consumption and had data of dual-energy X-ray absorptiometry (DXA) examination. Bone mineral density (BMD) was measured using DXA at the femoral neck and lumbar spine and osteoporosis was defined by World Health Organization T-score criteria in addition to self-report of current anti-osteoporotic medication use. After adjusting for various demographic and lifestyle confounders (including hormonal factors), subjects in the highest quartile of coffee intake had 36% lower odds for osteoporosis compared to those in the lowest quartile (Adjusted odds ratio [aOR] = 0.64; 95% confidence interval [CI], 0.43-0.95; P for trend = 0.015). This trend was consistent in osteoporosis of lumbar spine and femoral neck (aOR = 0.65 and 0.55; P for trend = 0.026 and 0.003, respectively). In addition, age- and body mass index (BMI)-adjusted BMD of the femoral neck and lumbar spine increased with higher coffee intake (P for trend = 0.019 and 0.051, respectively). Coffee consumption may have protective benefits on bone health in Korean postmenopausal women in moderate amount. Further, prospective studies are required to confirm this association.

Objectives To examine the role of alcohol at the time of aggressive incidents between intimate partners in the general population by gender, by estimating (1) prevalence and severity of aggression, and drinking at the time, (2) associations of drinking at the time of the aggression with reported severity, anger and fear, and (3) association of usual drinking patterns with partner aggression. Design A national survey of 18–70-year-olds using an electoral roll sample obtained self-reported alcohol consumption, partner's alcohol consumption and details of the most severe partner aggression by the respondent and towards the respondent in the past 2 years. The mean scores for associated severity, anger and fear were analysed by gender and alcohol involvement. Multinomial models estimated associations of drinking patterns with aggression to and from the respondent. Results The response rate was 49% (n=1925). Men and women reported similar prevalence of victimisation and perpetration of aggression (11–15%). Alcohol was involved in more than 25% of incidents, and reported more by women than by men, particularly male-only drinking when the respondent was the victim. Women reported greater severity, anger and fear with victimisation than men, and drinking was associated with greater reported severity. Heavy episodic drinking by respondents was associated with a threefold increase in victimisation and doubling of perpetration of aggression involving alcohol. Heavy episodic drinking by either partner was also associated with drinking being involved in reported aggression. Conclusions The experience of intimate-partner aggression in a cross-section of households differs by gender and the involvement of alcohol, and ‘counts’ of aggressive acts in a population-based survey do not reflect the reality of gender differences. Heavy episodic drinking patterns are associated with more aggression involving alcohol within relationships, and alcohol involvement is associated

This study aimed to explore variations in the provision of integrated academic surgical training across the UK. This is an online cross-sectional survey (consisting of 44 items with a range of free-text, binomial and 5-point Likert scale responses) developed by the Association of Surgeons in Training. A self-reported survey instrument was distributed to academic surgical trainees across the UK (n=276). 143 (51.9%) responses were received (81% male, median age: 34 years), spanning all UK regions and surgical specialties. Of the 143 trainees, 29 were core trainees (20.3%), 99 were specialty trainees (69.2%) and 15 (10.5%) described themselves as research fellows. The structure of academic training varied considerably, with under a third of trainees receiving guaranteed protected time for research. Despite this, however, 53.1% of the respondents reported to be satisfied with how their academic training was organised. Covering clinical duties during academic time occurred commonly (72.7%). Although most trainees (n=88, 61.5%) met with their academic supervisor at least once a month, six (4.2%) never had an academic supervisory meeting. Most trainees (n=90, 62.9%) occupied a full-time rota slot and only 9.1% (n=13) described their role as 'supernumerary'. Although 58.7% (n=84) of the trainees were satisfied with their clinical competence, 37.8% (n=54) felt that clinical time focused more on service provision than the acquisition of technical skills. 58 (40.6%) had experienced some form of negative sentiment relating to their status as an academic trainee. Integrated academic training presents unique challenges and opportunities within surgery. This survey has identified variation in the quality of current programmes, meaning that the future provision of integrated surgical academic training should be carefully considered. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Ford, Allison; MacKintosh, Anne Marie; Moodie, Crawford; Richardson, Sol; Hastings, Gerard

2013-01-01

Objectives To compare adolescents’ responses to three different styles of cigarette packaging: novelty (branded packs designed with a distinctive shape, opening style or bright colour), regular (branded pack with no special design features) and plain (brown pack with a standard shape and opening and all branding removed, aside from brand name). Design Cross-sectional in-home survey. Setting UK. Participants Random location quota sample of 1025 never smokers aged 11–16 years. Main outcome measures Susceptibility to smoking and composite measures of pack appraisal and pack receptivity derived from 11 survey items. Results Mean responses to the three pack types were negative for all survey items. However, ‘novelty’ packs were rated significantly less negatively than the ‘regular’ pack on most items, and the novelty and regular packs were rated less negatively than the ‘plain’ pack. For the novelty packs, logistic regressions, controlling for factors known to influence youth smoking, showed that susceptibility was associated with positive appraisal and also receptivity. For example, those receptive to the innovative Silk Cut Superslims pack were more than four times as likely to be susceptible to smoking than those not receptive to this pack (AOR=4.42, 95% CI 2.50 to 7.81, p<0.001). For the regular pack, an association was found between positive appraisal and susceptibility but not with receptivity and susceptibility. There was no association with pack appraisal or receptivity for the plain pack. Conclusions Pack structure (shape and opening style) and colour are independently associated, not just with appreciation of and receptivity to the pack, but also with susceptibility to smoke. In other words, those who think most highly of novelty cigarette packaging are also the ones who indicate that they are most likely to go on to smoke. Plain packaging, in contrast, was found to directly reduce the appeal of smoking to adolescents. PMID:24056481

Guidelines for the assessment of non-alcoholic fatty liver disease (NAFLD) have been published in 2016 by National Institute for Health and Care Excellence and European Associations for the study of the Liver-European Association for the study of Diabetes-European Association for the study of Obesity. Prior to publication of these guidelines, we performed a cross-sectional survey of gastroenterologists and hepatologists regarding NAFLD diagnosis and management. An online survey was circulated to members of British Association for the Study of the Liver and British Society of Gastroenterology between February 2016 and May 2016. 175 gastroenterologists/hepatologists responded, 116 completing the survey, representing 84 UK centres. 22% had local NAFLD guidelines. 45% received >300 referrals per year from primary care for investigation of abnormal liver function tests (LFTs). Clinical assessment tended to be performed in secondary rather than primary care including body mass index (82% vs 26%) and non-invasive liver screen (86% vs 32%) and ultrasound (81% vs 37%). Widely used tools for non-invasive fibrosis risk stratification were aspartate transaminase (AST)/alanine transaminase (ALT) ratio (53%), Fibroscan (50%) and NAFLD fibrosis score (41%). 78% considered liver biopsy in selected cases. 50% recommended 10% weight loss target as first-line treatment. Delivery of lifestyle interventions was mostly handed back to primary care (56%). A minority have direct access to community weight management services (22%). Follow-up was favoured by F3/4 fibrosis (72.9%), and high-risk non-invasive fibrosis tests (51%). Discharge was favoured by simple steatosis at biopsy (30%), and low-risk non-invasive scores (25%). The survey highlights areas for improvement of service provision for NAFLD assessment including improved recognition of non-alcoholic steatohepatitis in people with type 2 diabetes, streamlining abnormal LFT referral pathways, defining non-invasive liver fibrosis

Objective To examine if streamlining a medical research funding application process saved time for applicants. Design Cross-sectional surveys before and after the streamlining. Setting The National Health and Medical Research Council (NHMRC) of Australia. Participants Researchers who submitted one or more NHMRC Project Grant applications in 2012 or 2014. Main outcome measures Average researcher time spent preparing an application and the total time for all applications in working days. Results The average time per application increased from 34 working days before streamlining (95% CI 33 to 35) to 38 working days after streamlining (95% CI 37 to 39; mean difference 4 days, bootstrap p value <0.001). The estimated total time spent by all researchers on applications after streamlining was 614 working years, a 67-year increase from before streamlining. Conclusions Streamlined applications were shorter but took longer to prepare on average. Researchers may be allocating a fixed amount of time to preparing funding applications based on their expected return, or may be increasing their time in response to increased competition. Many potentially productive years of researcher time are still being lost to preparing failed applications. PMID:25596201

Lee, Lai-Kah; Chen, Paul C Y; Lee, Kick-Kit; Kaur, Jagmohni

2007-03-01

The aim of this study was to determine the prevalence of violence-related behaviours among adolescents and the factors associated with it. This was a cross-sectional school survey conducted on 4500 adolescent students, using a structured questionnaire. Data were collected using the supervised self-administered questionnaire [a modified version of the Youth Risk Behavior Surveillance in the Malaysian National Language (Bahasa Malaysia)]. Our study showed that 27.9% of students had been involved in a physical fight, 6.6% had been injured in a fight, 5.9% had carried a weapon, 7.2% had felt unsafe, 18.5% had had their money stolen and 55.0% had had their property stolen. Adolescents who carried weapons to school, smoked, used drugs, felt sad or hopeless and played truant were more likely to be involved in physical fights after adjusting for age, sex, and ethnicity. Violence-related behaviours among adolescents, especially involvement in physical fights, are common and are positively associated with certain factors such as smoking, taking drugs, playing truant, feeling sad or hopeless. Interventions designed at targeting adolescent violence should also address these factors and target the high-risk groups. There may be a need to identify and provide services for adolescents who exhibit these factors.

To examine trends in socioeconomic inequalities in major cardiovascular disease (CVD) risk factors among the Korean population. Cross-sectional study. A nationally representative population survey database. A total of 42 725 Koreans, aged 25-64 years, who participated in the Korean National Health and Nutrition Examination Survey (KNHANES) II (2001) to VI (2013-2014). Trends in socioeconomic inequalities in five major CVD risk factors (smoking, obesity, diabetes, hypertension and hypercholesterolaemia). Gender differences were noted in the time trends in socioeconomic inequalities in smoking, obesity, diabetes and hypertension. Among men, low socioeconomic status (SES) was associated with higher prevalence of smoking, but not with obesity, diabetes or hypertension. The magnitudes of socioeconomic inequalities in smoking, obesity and diabetes remained unchanged, and the magnitude of the inequality in hypertension decreased over time. However, among women, low SES was associated with higher prevalence of smoking, obesity, diabetes and hypertension. Time trends towards increasing socioeconomic inequalities, measured by income, in smoking, obesity and diabetes were found in women. Unlike the other CVD risk factors, hypercholesterolaemia was not associated with socioeconomic inequality. SES had a stronger impact on major CVD risk factors among Korean women than men. Moreover, socioeconomic inequalities in smoking, obesity and diabetes worsened among Korean women over time. Public policies to prevent smoking, obesity and diabetes in women with lower SES are needed to address inequalities. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

2018-04-27

When a family member is diagnosed with schizophrenia, it causes stress to the caregiver that can eventually result in missed work days and lower work performance. This study aims at revealing productivity costs for caregivers of schizophrenia patients in Japan. A cross-sectional survey of caregivers was conducted and resulted in 171 respondents. The assessment of work productivity included calculating the costs of absenteeism, presenteeism and total productivity costs. This was accomplished using the "Work Productivity and Activity Impairment Questionnaire" (WPAI). A relative majority of caregivers in the sample provided care for their spouse (47%), 18% cared for their brother or sister and 16% provided care for their child. Per capita productivity costs totaled JPY 2.42 million, with JPY 2.36 million (97%) of that amount being due to presenteeism. The burden on caregivers is substantial enough to warrant structured support programs aimed at maintaining careers' physical and mental health, helping them provide more effective care to schizophrenia patients and eventually increase productivity at work.

A New Measurement of Neutron Induced Fission Cross Sections

NASA Astrophysics Data System (ADS)

Magee, Joshua; Niffte Collaboration

2017-09-01

Neutron induced fission cross sections of actinides are of great interest in nuclear energy and stockpile stewardship. Traditionally, measurements of these cross sections have been made with fission chambers, which provide limited information on the actual fragments, and ultimately result in uncertainties on the order of several percent. The Neutron Induced Fission ragment Tracking Experiment (NIFFTE) collaboration designed and built a fission Time Projection Chamber (fissionTPC), which provides additional information on these processes, through 3-dimensional tracking, improved particle identification, and in-situ profiles of target and beam non-uniformities. Ultimately, this should provide sub-percent measurements of (n,f) cross-sections. During the 2016 run cycle, measurements of the 238U(n,f)/235U(n,f) cross section shape was performed at the Los Alamos Neutron Science Center (LANSCE) Weapons Neutron Research (WNR) facility. An overview of the fission TPC will be given, as well as these recently reported results. This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.

Background Reliance on national figures may be underestimating the extent of mental ill health in urban communities. This study demonstrates the necessity for local information on common mental disorder (CMD) and substance use by comparing data from the South East London Community Health (SELCoH) study with those from a national study, the 2007 English Adult Psychiatric Morbidity Study (APMS). Methodology/Principal Findings Data were used from two cross-sectional surveys, 1698 men and women residing in south London and 7403 men and women in England. The main outcome, CMD, was indicated by a score of 12 or above on the Revised Clinical Interview Schedule. Secondary outcomes included hazardous alcohol use and illicit drug use. SELCoH sample prevalence estimates of CMD were nearly twice that of the APMS England sample estimates. There was a four-fold greater proportion of depressive episode in the SELCoH sample than the APMS sample. The prevalence of hazardous alcohol use was higher in the national sample. Illicit drug use in the past year was higher in the SELCoH sample, with cannabis and cocaine the illicit drugs reported most frequently in both samples. In comparisons of the SELCoH sample with the APMS England sample and the APMS sample from the Greater London area in combined datasets, these differences remained after adjusting for socio-demographic and socioeconomic indicators for all outcomes. Conclusions/Significance Local information for estimating the prevalence of CMD and substance use is essential for surveillance and service planning. There were similarities in the demographic and socioeconomic factors related to CMD and substance use across samples. PMID:23251330

Introduction: Undoubtedly, diabetes is an incremental threat for the world health and substantial evidence now suggest that diabetes is strongly associated with patients’ unhealthy lifestyle, behavioral patterns, and socioeconomic changes. Treatment modalities, in particular to this disease differs from patient to patient. In Ayurveda, this individuality is decided on the basis of Prakriti, Vaya, Bala, Desha etc., and hence it is essential to know these factors for successful management of diseases. Aim: To assess the role of demographic profile, changes in life style habits, dietary patterns, occupational and social background in increasing prevalence of type 2 diabete mellitus (DM) at Jamnagar region. Materials and Methods: A cross-sectional survey study was conducted on randomly selected 350 diabetic patients of Jamnagar region. A survey proforma was prepared and detailed history of each patient fulfilling the diagnostic criteria was taken along with demographic profile. Observations and Conclusion: The obtained data reveals that, certain faulty dietary and life style regimes of this region are responsible in manifestation of DM. Its magnitude and low awareness warrants appropriate public health interventions for its effective control. PMID:26730132

Objectives To identify gender-specific associations between education and income in relation to obesity in developed countries by considering both the interaction-effect terms of the independent variables and their main-effect terms. Design A cross-sectional study. Education and income levels were chosen as socioeconomic status indicators. Sociodemographics, lifestyles and medical conditions were used as covariates in multivariable logistic regression models. Adjusted ORs and predicted probabilities of being obese were computed and adjusted for a complex survey design. Setting Data were obtained from the Fifth Korea National Health and Nutrition Examination Survey (2010–2012). Participants The sample included 7337 male and 9908 female participants aged ≥19 years. Outcome measure Obesity was defined as body mass index of ≥25, according to a guideline for Asians. Results In models with no interaction-effect terms of independent variables, education was significantly associated with obesity in both men and women, but income was significant only in women. However, in models with the interaction-effect terms, education was significant only in women, but income was significant only in men. The interaction effect between income and education was significant in men but not in women. Participants having the highest predicted probability of being obese over educational and income levels differed between the two types of models, and between men and women. A prediction using the models with the interaction-effect terms demonstrated that for all men, the highest level of formal education was associated with an increase in their probability of being obese by as much as 26%. Conclusions The well-known, negative association between socioeconomic status and obesity in developed countries may not be valid when interaction effects are included. Ignoring these effects and their gender differences may result in the targeting of wrong populations for reducing obesity prevalence

Pre-hospital emergency care is a particularly vulnerable setting for workplace violence. However, there is no literature available to date on the psychological consequences of violence in pre-hospital emergency care. To evaluate the psychological consequences of exposure to workplace violence from patients and those accompanying them in pre-hospital emergency care. A retrospective cross-sectional study. 70 pre-hospital emergency care services located in Madrid region. A randomized sample of 441 health care workers (135 physicians, 127 nurses and 179 emergency care assistants). Data were collected from February to May 2012. The survey was divided into four sections: demographic/professional information, level of burnout determined by Maslach Burnout Inventory (MBI), mental health status using General Health Questionnaire (GHQ-28) and frequency and type of violent behaviour experienced by staff members. The health care professionals who had been exposed to physical and verbal violence presented a significantly higher percentage of anxiety, emotional exhaustion, depersonalization and burnout syndrome compared with those who had not been subjected to any aggression. Frequency of verbal violence (more than five times) was related to emotional exhaustion and depersonalization. Type of violence (i.e. physical aggression) is especially related to high anxiety levels and frequency of verbal aggression is associated with burnout (emotional exhaustion and depersonalization). Psychological counselling should be made available to professional staff who have been subjected to physical aggression or frequent verbal violence. Copyright © 2014 Elsevier Ltd.

Younes, W; Britt, H C

In a recent paper submitted to Phys. Rev. C they have presented estimates for (n,f) cross sections on a series of Thorium, Uranium and Plutonium isotopes over the range E{sub n} = 0.1-2.5 MeV. The (n,f) cross sections for many of these isotopes are difficult or impossible to measure in the laboratory. The cross sections were obtained from previous (t,pf) reaction data invoking a model which takes into account the differences between (t,pf) and (n,f) reaction processes, and which includes improved estimates for the neutron compound formation process. The purpose of this note is: (1) to compare the estimated crossmore » sections to current data files in both ENDF and ENDL databases; (2) to estimate ratios of cross sections relatively to {sup 235}U integrated over the ''tamped flattop'' critical assembly spectrum that was used in the earlier {sup 237}U report; and (3) to show the effect on the integral cross sections when the neutron capturing state is an excited rotational state or an isomer. The isomer and excited state results are shown for {sup 235}U and {sup 237}U.« less

Despite being highly educated in comparison with women in other member countries of the Organisation for Economic Cooperation and Development, Japanese women are expected to assume traditional gender roles, and many dedicate themselves to full-time housewifery. Women working outside the home do so under poor conditions, and their health may not be better than that of housewives. This study compared the self-rated health status and health behaviours of housewives and working women in Japan. Cross-sectional survey. A national university in Tokyo with 9864 alumnae. A total 1344 women who graduated since 1985 and completed questionnaires in an anonymous mail-based survey. Health anxiety and satisfaction, receipt of health check-ups, eating breakfast, smoking, and sleep problems according to job status and family demands: housewives (n=247) and working women with (n=624) and without (n=436) family demands. ORs were used for risk assessment, with housewives as a reference. After adjustment for satisfaction with present employment status and other confounding factors, working women were more likely than housewives to feel health anxiety (with family demands, OR: 1.68, 95% CI1.10 to 2.57; without family demands, OR: 3.57, 95% CI 2.19 to 4.50) and health dissatisfaction (without family demands, OR: 3.50, 95% CI 2.35 to 5.21); they were also more likely than housewives to eat an insufficient breakfast (with family demands, OR: 1.91, 95% CI 1.22 to 3.00; without family demands, OR: 4.02, 95% CI 2.47 to 6.57) and to have sleep problems (ORs: 2.08 to 4.03). No healthy-worker effect was found among Japanese women. Housewives, at least those who are well educated, appear to have better health status and health-related behaviours than do working women with the same level of education.

Provision of National Health Service (NHS) specialist chronic fatigue syndrome or myalgic encephalomyelitis (CFS/ME) services in England has been deemed patchy and inconsistent. Our objective was to explore variation in the provision of NHS specialist CFS/ME services and to investigate whether access is related to measures of deprivation and inequality. Survey of all CFS/ME clinical teams in England, plus cross-sectional data from a subset of teams. Secondary care. We used clinic activity data from CFS/ME clinical teams in England to describe provision of specialist CFS/ME services (referral, assessment and diagnosis rates per 1000 adults per year) during 2008-2011 according to Primary Care Trust (PCT) population estimates, and to investigate whether use of services was related to PCT-level measures of deprivation and inequality. We used postcode data from seven services to investigate variation in provision by deprivation. Clinic activity data were obtained from 93.9% (46/49) of clinical teams in England which between them received referrals from 84.9% (129/152) of PCTs. 12 PCTs, covering a population of 2.08 million adults, provided no specialist CFS/ME service. There was a six-fold variation in referral and assessment rates between services which could not be explained by PCT-level measures of deprivation and inequality. The median assessment rate in 2010 was 0.25 (IQR 0.17, 0.35) per 1000 adults per year. 91.9% (IQR 76.5%, 100.0%) of adults assessed were diagnosed with CFS/ME. Postcode data from seven clinical teams showed that assessment rates were equal across deprivation quartiles for four teams but were 40-50% lower in the most deprived compared with the most affluent areas for three teams. Two million adults in England do not have access to a specialist CFS/ME service. In some areas which do have a specialist service, access is inequitable. This inequity may worsen with the impending fragmentation of NHS commissioning across England.

This study aimed to investigate the perceptions of primary care workers about the impacts of the national essential medicines policy (NEMP). A cross-sectional questionnaire survey was undertaken in 42 urban community health centres randomly selected from four provinces in China. 791 primary care workers rated the impacts of the NEMP on a 5-point Likert scale. An average score for the impacts of the NEMP on four aspects (the practice of health workers, interactions of patients with health workers, operations of health centres and provision of medicines) was calculated, each ranging from 0 to 100. A higher score indicates a more positive rating. Linear regression models were established to determine the sociodemographic characteristics (region, age, gender, profession, training, income) that were associated with the ratings. The respondents gave an average rating score of 65.61±11.76, 63.17±13.62, 66.35±13.02 and 67.26±11.60 for the impacts of the NEMP on health workers, patients, health centres and provision of medicines, respectively. Respondents from the central region rated the NEMP higher than those from the eastern and western regions. The pharmacists (β=5.457~7.558, p<0.001) and nurses (β=2.612~3.107, p<0.05) gave a more positive rating on the NEMP than their physician counterparts. A higher income was found to be associated with a decrease in the NEMP ratings. Repetitive training was a predictor of higher ratings. The NEMP has significant impacts (as perceived by the health workers) on health services delivery in primary care settings. However, the impacts of the NEMP vary by region, professional practice and the income level of health workers. It is important to maintain support from physicians through income subsidies (to compensate for potential loss) and training. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

OBJECTIVES: To survey operating theatre and intensive care unit staff about attitudes concerning error, stress, and teamwork and to compare these attitudes with those of airline cockpit crew. DESIGN:: Cross sectional surveys. SETTING:: Urban teaching and non-teaching hospitals in the United States, Israel, Germany, Switzerland, and Italy. Major airlines around the world. PARTICIPANTS:: 1033 doctors, nurses, fellows, and residents working in operating theatres and intensive care units and over 30 000 cockpit crew members (captains, first officers, and second officers). MAIN OUTCOME MEASURES:: Perceptions of error, stress, and teamwork. RESULTS:: Pilots were least likely to deny the effects of fatigue on performance (26% v 70% of consultant surgeons and 47% of consultant anaesthetists). Most pilots (97%) and intensive care staff (94%) rejected steep hierarchies (in which senior team members are not open to input from junior members), but only 55% of consultant surgeons rejected such hierarchies. High levels of teamwork with consultant surgeons were reported by 73% of surgical residents, 64% of consultant surgeons, 39% of anaesthesia consultants, 28% of surgical nurses, 25% of anaesthetic nurses, and 10% of anaesthetic residents. Only a third of staff reported that errors are handled appropriately at their hospital. A third of intensive care staff did not acknowledge that they make errors. Over half of intensive care staff reported that they find it difficult to discuss mistakes. CONCLUSIONS: Medical staff reported that error is important but difficult to discuss and not handled well in their hospital. Barriers to discussing error are more important since medical staff seem to deny the effect of stress and fatigue on performance. Further problems include differing perceptions of teamwork among team members and reluctance of senior theatre staff to accept input from junior members.

Iodine is a key component of the thyroid hormones, which are critical for healthy growth, development and metabolism. The UK population is now classified as mildly iodine-insufficient. Adequate levels of iodine during pregnancy are essential for fetal neurodevelopment, and mild iodine deficiency is linked to developmental impairments. In the absence of prophylaxis in the UK, awareness of nutritional recommendations during pregnancy would empower mothers to make the right dietary choices leading to adequate iodine intake. The present study aimed to: estimate mothers' dietary iodine intake in pregnancy (using a FFQ); assess awareness of the importance of iodine in pregnancy with an understanding of existing pregnancy dietary and lifestyle recommendations with relevance for iodine; examine the level of confidence in meeting adequate iodine intake. A cross-sectional survey was conducted and questionnaires were distributed between August 2011 and February 2012 on local (Glasgow) and national levels (online electronic questionnaire); 1026 women, UK-resident and pregnant or mother to a child aged up to 36 months participated in the study. While self-reported awareness about general nutritional recommendations during pregnancy was high (96 %), awareness of iodine-specific recommendations was very low (12 %), as well as the level of confidence of how to achieve adequate iodine intake (28 %). Median pregnancy iodine intake, without supplements, calculated from the FFQ, was 190 μg/d (interquartile range 144-256μg/d), which was lower than that of the WHO's recommended intake for pregnant women (250 μg/d). Current dietary recommendations in pregnancy, and their dissemination, are found not to equip women to meet the requirements for iodine intake.

A simple but comprehensive theory of nuclear reactions is presented. Extensive tables of nucleon, deuteron, and heavy-ion absorption cross sections over a broad range of energies are generated for use in cosmic ray shielding studies. Numerous comparisons of the calculated values with available experimental data show agreement to within 3 percent for energies above 80 MeV/nucleon and within approximately 10 percent for energies as low as 30 MeV/nucleon. These tables represent the culmination of the development of the absorption cross section formalism and supersede the preliminary absorption cross sections published previously in NASA TN D-8107, NASA TP-2138, and NASA TM-84636.

In support of the Source Physics Experiment (SPE) at the Nevada National Security Site (NNSS), we have conducted two cross-borehole seismic experiments in the Climax Stock. The first experiment was conducted prior to the third shot in this multi-detonation program using two available boreholes and the shot hole, while the second experiment was conducted after the shot using four of the available boreholes. The first study focused on developing a well-characterized 2D pre-explosion Vp model including two VSPs and a seismic refraction survey, as well as quantifying baseline waveform similarity at reoccupied sites. This was accomplished by recording both "sparker" and accelerated weight drop sources on a hydrophone string and surface geophones. In total more than 18,500 unique source-receiver pairs were acquired during this testing. In the second experiment, we reacquired aproximately 8,800 source-receiver pairs and performed a cross-line survey allowing for a 3D post-explosion Vp model. The data acquired from the reoccupied sites was processed using cross-correlation methods and change detection methodologies, including comparison of the tomographic images. The survey design and subsequent processing provided an opportunity to investigate seismic wave propagation through damaged rock. We also performed full waveform forward modelling for a granitic body hosting a perched aquifer.

Haga, A; Nakagawa, K; Kotoku, J

2015-06-15

Purpose: The importance of the precision in photoelectric cross-section value increases for recent developed technology such as dual energy computed tomography, in which some reconstruction algorithms require the energy dependence of the photo-absorption in each material composition of human being. In this study, we revisited the photoelectric cross-section calculation by self-consistent relativistic Hartree-Fock (HF) atomic model and compared with that widely distributed as “XCOM database” in National Institute of Standards and Technology, which was evaluated with localdensity approximation for electron-exchange (Fock)z potential. Methods: The photoelectric cross section can be calculated with the electron wave functions in initial atomic state (boundmore » electron) and final continuum state (photoelectron). These electron states were constructed based on the selfconsistent HF calculation, where the repulsive Coulomb potential from the electron charge distribution (Hartree term) and the electron exchange potential with full electromagnetic interaction (Fock term) were included for the electron-electron interaction. The photoelectric cross sections were evaluated for He (Z=2), Be (Z=4), C (Z=6), O (Z=8), and Ne (Z=10) in energy range of 10keV to 1MeV. The Result was compared with XCOM database. Results: The difference of the photoelectric cross section between the present calculation and XCOM database was 8% at a maximum (in 10keV for Be). The agreement tends to be better as the atomic number increases. The contribution from each atomic shell has a considerable discrepancy with XCOM database except for K-shell. However, because the photoelectric cross section arising from K-shell is dominant, the net photoelectric cross section was almost insensitive to the different handling in Fock potential. Conclusion: The photoelectric cross-section program has been developed based on the fully self-consistent relativistic HF atomic model. Due to small effect on the

The aim of this study is to investigate the associations between social capital and antenatal depression among Chinese primiparas. A cross-sectional design was used and a questionnaire survey was conducted with 1471 participants using the intercept method at the provincial hospital in Zhejiang in 2016. Antenatal depression was evaluated using the Edinburgh Postnatal Depression Scale (EPDS) and social capital was assessed by the Chinese version of Social Capital Assessment Questionnaire (C-SCAQ). The prevalence of antenatal depression was assessed among Chinese primiparas in their third trimesters. The antenatal depression prevalence among sub-groups with lower social trust (ST), social reciprocity (SR), social network (SN), and social participation (SP) were significantly higher than those among higher score sub-groups. In the fully adjusted model, primiparas' antenatal depression was significantly associated with ST, SR, SN, and SP. Compared to the structural social capital, the cognitive social capital was a more crucial dimension to the prevalence of antenatal depression. For future community pregnancy health care management programs in China, it might be beneficial to add more social capital related intervention. Copyright © 2017 Elsevier B.V. All rights reserved.

A positive attitude toward evidence-based practice (EBP) has been identified as an important factor in the effectiveness of the dissemination and implementation of EBP in real-world settings. The objectives of this study were: (1) to describe dimensions of Icelandic physical therapists' attitudes toward the adoption of new knowledge and EBP and (2) to explore the association between attitudes and selected personal and environmental factors. This study was a cross-sectional, Web-based survey of the total population of full members of the Icelandic Physiotherapy Association. The Evidence-Based Practice Attitude Scale (EBPAS) was used to survey attitudes toward EBP; the total EBPAS and its 4 subscales (requirements, appeal, openness, and divergence) were included. Linear regression was used to explore the association between the EBPAS and selected background variables. The response rate was 39.5% (N=211). The total EBPAS and all of its subscales reflected physical therapists' positive attitudes toward the adoption of new knowledge and EBP. Multivariable analysis revealed that being a woman was associated with more positive attitudes, as measured by the total EBPAS and the requirements, openness, and divergence subscales. Physical therapists with postprofessional education were more positive, as measured by the EBPAS openness subscale, and those working with at least 10 other physical therapists demonstrated more positive attitudes on the total EBPAS and the openness subscale. Because this was a cross-sectional survey, no causal inferences can be made, and there may have been unmeasured confounding factors. Potential nonresponse bias limits generalizability. The results expand understanding of the phenomenon of attitudes toward EBP. They reveal potentially modifiable dimensions of attitudes and the associated characteristics of physical therapists and their work environments. The findings encourage investigation of the effectiveness of strategies aimed at influencing

The aim of this study is to investigate the remission rate of rheumatoid arthritis (RA) in China and identify its potential determinants. A multi-center cross-sectional study was conducted from July 2009 to January 2012. Data were collected by face-to-face interviews of the rheumatology outpatients in 28 tertiary hospitals in China. The remission rates were calculated in 486 RA patients according to different definitions of remission: the Disease Activity Score in 28 joints (DAS28), the Simplified Disease Activity Index (SDAI), the Clinical Disease Activity Index (CDAI), and the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) Boolean definition. Potential determinants of RA remission were assessed by univariate and multivariate analyses. The remission rates of RA from this multi-center cohort were 8.6% (DAS28), 8.4% (SDAI), 8.2% (CDAI), and 6.8% (Boolean), respectively. Favorable factors associated with remission were: low Health Assessment Questionnaire (HAQ) score, absence of rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP), and treatment of methotrexate (MTX) and hydroxychloroquine (HCQ). Younger age was also predictive for the DAS28 and the Boolean remission. Multivariate analyses revealed a low HAQ score, the absence of anti-CCP, and the treatment with HCQ as independent determinants of remission. The clinical remission rate of RA patients was low in China. A low HAQ score, the absence of anti-CCP, and HCQ were significant independent determinants for RA remission.

Demonstrate how the Surgeons OverSeas Assessment of Surgical Need (SOSAS) can be used to determine the burden of head and neck (H&N) surgical disease in developing countries and identify reasons for untreated disease. Cluster randomized, cross-sectional, countrywide survey. Sierra Leone. The survey was administered to 75 of 9671 enumeration areas in Sierra Leone between January 9 and February 3, 2012, with 25 households in each cluster randomly selected for the survey. A household representative and 2 randomly selected household members were interviewed. Need for surgical care was based on participants' responses to whether they had an H&N condition that they believed needed surgical care. Of 1875 households, data were analyzed for 1843 (98%), with 3645 total respondents. Seven hundred and one H&N surgical conditions were reported as occurring during the lifetime of the 3645 respondents (19.2%).The current prevalence of H&N conditions in need of a surgical consultation was 11.8%. No money (60.1%) was the most common reason respondents reported for not receiving medical care. A bivariate analysis demonstrated that age, village type, education, and type of condition may be predictors for seeking health care and/or receiving surgical care. These results show limited access for patients to be evaluated for a potential H&N surgical condition in Sierra Leone. The true incidence of untreated surgical disease is unknown as most respondents were not evaluated by a surgeon. This survey could be used in other countries as health care professionals assess surgical needs throughout the world. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

The presence of antibodies to human T-lymphotropic virus (HTLV) types 1 and 2 was examined in 5742 sera belonging to consecutive adult outpatients attended during June 2008 at 13 different hospitals across Spain. Overall, 58.8% were female. Foreigners represented 8% of the study population. Seven individuals were seropositive for HTLV-2 (overall prevalence 0.12%). No cases of HTLV-1 infection were found. All HTLV-2(+) subjects were Spanish natives, of whom six were coinfected with HIV-1 and five with hepatitis C virus (HCV). Moreover, all but one of the HTLV-2(+) subjects had been intravenous drug users. In summary, this cross-sectional survey suggests that the rate of HTLV infection in Spain is low, and is mostly represented by HTLV-2. Infected individuals are generally Spanish natives with a prior history of intravenous drug use and are coinfected with HIV-1 and/or HCV.

Background Sleep is important in terms of good general health and appropriate sleep duration has been linked to quality-of-life. Dysphonia may impair communication and social relationships, and is thus also closely related to quality-of-life. No large-scale, cross-sectional epidemiological study of a sample representative of the population of an entire country has yet assessed the possible existence of a relationship between sleep duration and dysphonia. Methods We investigated a possible association between subjective voice problems and self-reported sleep duration in South Korean subjects using 2010–2012 data from the Korean National Health and Nutrition Examination Survey (KNHANES). Cross-sectional data on 17,806 adults (7,578 males and 10,228 females) over the age of 19 years who completed the KNHANES were analyzed. All participants reported voice problems (if present) and their daily average sleep duration using a self-reporting questionnaire. Sleep duration was classified into five categories as follows: ≤5, 6, 7, 8, and ≥9 h/day. Results The overall prevalence of dysphonia was 6.8%; 5.7% in males and 7.7% in females. The prevalence for dysphonia by sleep duration exhibited a U-shape, with the lowest point being at sleep duration of 7-8h. After adjustment for covariates (age, sex, smoking status, alcohol consumption, regular exercise, low income, high-level education), a sleep duration of ≤5 h (OR = 1.454; 95% CI, 1.153–1.832) and a sleep duration of ≥9 h (OR = 1.365; 95% CI, 1.017–1.832) were significantly associated with dysphonia, compared to a sleep duration of 7 h. In terms of gender, males who slept for ≥9 h were at a 2-fold (OR = 2.028; 95% CI, 1.22–3.35) higher odds for dysphonia (p<0.05) compared to those who slept for 7 h. A sleep duration ≤5 h was associated with a 1.6-fold (OR = 1.574; 95% CI, 1.203–2.247) higher odds of dysphonia ≥3 weeks in duration (long-term dysphonia).

An accurate and up-to-date estimate of the potential reach of Internet-based smoking cessation interventions (ISCIs) would improve calculations of impact while an understanding of the characteristics of potential users would facilitate the design of interventions. This study reports the prevalence and the sociodemographic, smoking, and Internet-use characteristics of smokers interested in using ISCIs in a nationally representative sample. Data were collected using cross-sectional household surveys of representative samples of adults in England. Interest in trying an Internet site or "app" that was proven to help with stopping smoking was assessed in 1128 adult smokers in addition to sociodemographic characteristics, dependence, motivation to quit, previous attempts to quit smoking, Internet and handheld computer access, and recent types of information searched online. Of a representative sample of current smokers, 46.6% (95% CI 43.5%-49.6%) were interested in using an Internet-based smoking cessation intervention. In contrast, only 0.3% (95% CI 0%-0.7%) of smokers reported having used such an intervention to support their most recent quit attempt within the past year. After adjusting for all other background characteristics, interested smokers were younger (OR=0.98, 95% CI 0.97-0.99), reported stronger urges (OR=1.29, 95% CI 1.10-1.51), were more motivated to quit within 3 months (OR=2.16, 95% CI 1.54-3.02), and were more likely to have made a quit attempt in the past year (OR=1.76, 95% CI 1.30-2.37), access the Internet at least weekly (OR=2.17, 95% CI 1.40-3.36), have handheld computer access (OR=1.65, 95% CI 1.22-2.24), and have used the Internet to search for online smoking cessation information or support in past 3 months (OR=2.82, 95% CI 1.20-6.62). There was no association with social grade. Almost half of all smokers in England are interested in using online smoking cessation interventions, yet fewer than 1% have used them to support a quit attempt in the

To compare estimates of dental visits among adults using three national surveys. Cross-sectional data from the National Health Interview Survey (NHIS), National Health and Nutrition Examination Survey (NHANES), and National Health Expenditure surveys (NMCES, NMES, MEPS). This secondary data analysis assessed whether overall estimates and stratum-specific trends are different across surveys. Dental visit data are age standardized via the direct method to the 1990 population of the United States. Point estimates, standard errors, and test statistics are generated using SUDAAN. Sociodemographic, stratum-specific trends are generally consistent across surveys; however, overall estimates differ (NHANES III [364-day estimate] versus 1993 NHIS: -17.5 percent difference, Z = 7.27, p value < 0.001; NHANES III [365-day estimate] vs. 1993 NHIS: 5.4 percent difference, Z = -2.50, p value = 0.006; MEPS vs. 1993 NHIS: -29.8 percent difference, Z = 16.71, p value < 0.001). MEPS is the least susceptible to intrusion, telescoping, and social desirability. Possible explanations for discrepancies include different reference periods, lead-in statements, question format, and social desirability of responses. Choice of survey should depend on the hypothesis. If trends are necessary, choice of survey should not matter however, if health status or expenditure associations are necessary, then surveys that contain these variables should be used, and if accurate overall estimates are necessary, then MEPS should be used. A validation study should be conducted to establish "true" utilization estimates.

To examine nurse employees' and employers' views about responsibilities for managing nurses' careers. Career management policies are associated with cost savings, in terms of workforce recruitment and retention and an increase in job and career satisfaction. In nursing, responsibility for career management remains relatively unexplored. A multicenter, cross-sectional questionnaire survey. Data were collected from 871 nurse employees and employers in the British National Health Service. The study was conducted in 2008, a period when policy reforms aimed at modernizing the healthcare workforce in England. In the current discussions in Europe and the USA about the future of nursing, these data reveal insights not previously reported. Exploratory analyses were undertaken using descriptive and inferential statistics. The analysis indicated a temporal dimension to career management responsibilities. Short-term responsibilities for securing funding and time for development lay more with employers. Medium-term responsibilities for assessing nurses' strengths and weakness, determining job-related knowledge and skills and identifying education and training needs appeared to be shared. Long-term responsibilities for developing individual careers and future development plans lay primarily with employees. New ways of managing nurses' career development that lead to greater independence for employees and greater flexibility for employers, while retaining a high-calibre and competent workforce, are needed. Ultimately, career management responsibilities should not tilt to either side but rather be shared to benefit both parties. Clarifying employers' and employees' responsibilities for career management may help both parties to develop a common understanding of each other's role and to meet their obligations in a constructive dialogue. © 2014 John Wiley & Sons Ltd.

Educational outcomes associated with childhood obesity in the United States: cross-sectional results from the 2011–2012 National Survey of Children’s Health

PubMed Central

2015-01-01

Background Past research examining the effects of childhood obesity has largely focused on its projected effects into adulthood. However, there is emerging evidence that childhood obesity may have more immediate effects on school-related outcomes. We examine a range of educational attainment indicators to examine the possible pathway between obesity status and academic performance, while investigating the proximal effects of childhood obesity on health and utilization of health services, and whether these variables attenuate the relationship between obesity status and educational outcomes. Methods Data for the current study come from the 2011-2012 National Survey of Children’s Health, which details the impacts of childhood obesity on a range of outcomes among a nationally representative sample of children and adolescents aged 10-17 years (N=45,255). Educational outcomes (school absences, school problems, repeating a grade and school engagement) were modeled by logistic regression as a function of BMI, overall health status, health care utilization, and a range of sociodemographic variables. Results BMI status was significantly associated with all educational outcomes (p<0.001 for all), overall health status (p<0.001), and health care utilization (p=0.016). Prior to adjustment for covariates, obese children were significantly more likely to have school absences and school problems, to repeat a grade, and to have lower school engagement than non-overweight children. After adjustment for sociodemographic and health/healthcare variables, these outcomes remained significant for all but repeating a grade. The odds of having school problems, repeating a grade, and low school engagement that were associated with obesity were attenuated by the addition of sociodemographic variables into the model, while the addition of health and health care variables in the model decreased the odds of school absences. Conclusions This study provides evidence that increased weight status

There is a serious well-known problem of noticeable disagreements between the partial photoneutron cross sections obtained in various experiments. Such data were mainly determined using quasimonoenergetic annihilation photon beams and the method of neutron multiplicity sorting at Lawrence Livermore National Laboratory (USA) and Centre d'Etudes Nucleaires of Saclay (France). The analysis of experimental cross sections employing new objective physical data reliability criteria has shown that many of those are not reliable. The IAEA Coordinated Research Project (CRP) on photonuclear data evaluation was approved. The experimental and previously evaluated cross sections of the partial photoneutron reactions (γ ,1 n ) and (γ ,2 n ) on 197Au were analyzed using the new data reliability criteria. The data evaluated using the new experimental-theoretical method noticeably differ from both experimental data and data previously evaluated using nuclear modeling codes gnash, gunf, alice-f, and others. These discrepancies needed to be resolved.

To examine if streamlining a medical research funding application process saved time for applicants. Cross-sectional surveys before and after the streamlining. The National Health and Medical Research Council (NHMRC) of Australia. Researchers who submitted one or more NHMRC Project Grant applications in 2012 or 2014. Average researcher time spent preparing an application and the total time for all applications in working days. The average time per application increased from 34 working days before streamlining (95% CI 33 to 35) to 38 working days after streamlining (95% CI 37 to 39; mean difference 4 days, bootstrap p value <0.001). The estimated total time spent by all researchers on applications after streamlining was 614 working years, a 67-year increase from before streamlining. Streamlined applications were shorter but took longer to prepare on average. Researchers may be allocating a fixed amount of time to preparing funding applications based on their expected return, or may be increasing their time in response to increased competition. Many potentially productive years of researcher time are still being lost to preparing failed applications. Published by the BMJ Publishing Group Limited.

Obesity treatment is by large ineffective long term, and more emphasis on the prevention of excessive weight gain in childhood and adolescence is warranted. To inform energy balance related behaviour (EBRB) change interventions, insight in the potential personal, family and school environmental correlates of these behaviours is needed. Studies on such multilevel correlates of EBRB among schoolchildren in Europe are lacking. The ENERGY survey aims to (1) provide up-to-date prevalence rates of measured overweight, obesity, self-reported engagement in EBRBs, and objective accelerometer-based assessment of physical activity and sedentary behaviour and blood-sample biomarkers of metabolic function in countries in different regions of Europe, (2) to identify personal, family and school environmental correlates of these EBRBs. This paper describes the design, methodology and protocol of the survey. A school-based cross-sectional survey was carried out in 2010 in seven different European countries; Belgium, Greece, Hungary, the Netherlands, Norway, Slovenia, and Spain. The survey included measurements of anthropometrics, child, parent and school-staff questionnaires, and school observations to measure and assess outcomes (i.e. height, weight, and waist circumference), EBRBs and potential personal, family and school environmental correlates of these behaviours including the social-cultural, physical, political, and economic environmental factors. In addition, a selection of countries conducted accelerometer measurements to objectively assess physical activity and sedentary behaviour, and collected blood samples to assess several biomarkers of metabolic function. The ENERGY survey is a comprehensive cross-sectional study measuring anthropometrics and biomarkers as well as assessing a range of EBRBs and their potential correlates at the personal, family and school level, among 10-12 year old children in seven European countries. This study will result in a unique dataset

Critical care patients benefit from the attention of nursing personnel with a high competence level. The aim of the study was to describe and evaluate the self-assessed basic competence of intensive care unit nurses and related factors. A cross-sectional survey design was used. A basic competence scale (Intensive and Critical Care Nursing Competence Scale version 1, Likert scale 1–5, 1 = poor and 5 = excellent) was employed among Finnish intensive care unit nurses (n = 431). Intensive care unit nurses' self-assessed basic competence was good (mean 4.19, SD 0.40). The attitude and value base of basic competence was excellent whereas experience base was the poorest compared to the knowledge base and skill base of intensive and critical care nursing. The strongest factor explaining nurses' basic competence was their experience of autonomy in nursing care (F value 60.85, β 0.11, SE 0.01, and P ≤ 0.0001). Clinical competence was self-rated as good. Nurses gave their highest competence self-ratings for ICU patient care according to the principles of nursing care. The ICU nurses also self-rated their professional competence as good. Collaboration was self-rated as the best competence. In basic and continuing education and professional self-development discussions it is meaningful to consider and find solutions for how to improve nurses' experienced autonomy in nursing.

2014-09-01

Nuclear data such as neutron-induced fission cross sections play a fundamental role in nuclear energy and defense applications. In recent years, understanding of these systems has become increasingly dependent upon advanced simulation and modeling, where uncertainties in nuclear data propagate in the expected performances of existing and future systems. It is important therefore that uncertainties in nuclear data are minimized and fully understood. For this reason, the Neutron Induced Fission Fragment Tracking Experiment (NIFFTE) uses a Time Projection Chamber (TPC) to measure energy-differential (n,f) cross sections with unprecedented precision. The presentation will discuss how the capabilities of the NIFFTE TPC allow to directly measures systematic uncertainties in fission cross sections, in particular for what concerns fission-fragment identification, and target and beam uniformity. Preliminary results from recent analysis of 238U/235U and 239Pu/235U data collected with the TPC will be presented. This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.

Objective To estimate obesity prevalence among healthcare professionals in England and compare prevalence with those working outside of the health services. Design Cross-sectional study based on data from 5 years (2008–2012) of the nationally representative Health Survey for England. Setting England. Participants 20 103 adults aged 17–65 years indicating they were economically active at the time of survey classified into four occupational groups: nurses (n=422), other healthcare professionals (n=412), unregistered care workers (n=736) and individuals employed in non-health-related occupations (n=18 533). Outcome measure Prevalence of obesity defined as body mass index ≥30.0 with 95% CIs and weighted to reflect the population. Results Obesity prevalence was high across all occupational groups including: among nurses (25.1%, 95% CI 20.9% to 29.4%); other healthcare professionals (14.4%, 95% CI 11.0% to 17.8%); non-health-related occupations (23.5%, 95% CI 22.9% to 24.1%); and unregistered care workers who had the highest prevalence of obesity (31.9%, 95% CI 28.4% to 35.3%). A logistic regression model adjusted for sociodemographic composition and survey year indicated that, compared with nurses, the odds of being obese were significantly lower for other healthcare professionals (adjusted OR (aOR) 0.52, 95% CI 0.37 to 0.75) and higher for unregistered care workers (aOR 1.46, 95% CI 1.11 to 1.93). There was no significant difference in obesity prevalence between nurses and people working in non-health-related occupations (aOR 0.94, 95% CI 0.74 to 1.18). Conclusions High obesity prevalence among nurses and unregistered care workers is concerning as it increases the risks of musculoskeletal conditions and mental health conditions that are the main causes of sickness absence in health services. Further research is required to better understand the reasons for high obesity prevalence among healthcare professionals in England to inform interventions to

Proposed continuous-flow-electrophoresis (CFE) chamber of annular cross section offers advantages over conventional CFE chamber, and wedge-cross-section chamber described in "Increasing Sensitivity in Continuous-Flow Electrophoresis" (MFS-26176). In comparison with wedge-shaped chamber, chamber of annular cross section virtually eliminates such wall effects as electro-osmosis and transverse gradients of velocity. Sensitivity enhanced by incorporating gradient maker and radial (collateral) flow.

The objectives of this study were to determine the current staffing models of practice and the frequency of 24/7 coverage in academic medical centers in the United States and to assess the perceptions of critical care trainees and program directors toward these models. A cross-sectional national survey was conducted using an Internet-based survey platform. The survey was distributed to fellows and program directors of 374 critical care training programs in US academic medical centers. We received 518 responses: 138 from program directors (PDs) (37% of 374 programs) and 380 fellow responses. Coverage by a board-certified or board-eligible intensivist physician 24/7 was reported by 33% of PD respondents and was more common among pediatric and surgical critical care programs. Mandatory in-house call for critical care trainees was reported by 48% of the PDs. Mandatory call was also more common among pediatric-critical care programs compared with the rest (P < .001). Advanced nurse practitioners with critical care training were reported available by 27% of the PDs. The majority of respondents believed that 24/7 coverage would be associated with better patient care in the ICU and improved education for the fellows, although 65% of them believed this model would have a negative impact on trainees' autonomy. Intensivist coverage 24/7 was not commonly used in US academic centers responding to our survey. Significant differences in coverage models among critical care medicine specialties appear to exist. Program director and trainee respondents believed that 24/7 coverage was associated with better outcomes and education but also expressed concerns about the impact of this model on fellows' autonomy.

Poor mental health in adolescents has shown associations with engagement in other risk behaviours. However, evidence of this association in Sub-Saharan Africa, particularly South Africa, is lacking. This study examines the associations between pertinent risk behaviours and feelings of sadness or hopelessness amongst a nationally representative sample of South African school going adolescents. Data was analysed from the South African Youth Risk Behaviour Survey 2011 (n=10,997), a cross-sectional national survey among grades 8-11 school learners. Logistic regression examined the association of demographic, substance use, violent behaviour, sexual activity and suicidal plans and attempts with the primary outcome, feelings of sadness or hopelessness. Having feelings of sadness or hopelessness was significantly associated with more senior grades, being bullied (AOR:1.67, 95% CI: 1.42-1.96), being assaulted by a partner (1.33 [1.05-1.68]), forced sex (1.78 [1.37-2.32]); gang membership (1.32 [1.06-1.65]), binge drinking (1.37 [1.14-1.65]), ever having sex (1.23 [1.02-1.47]), having ≥1 partner/s in preceding three months (1.25 [1.02-1.53]), having made a plan to attempt suicide (2.50 [1.95-3.21]) and suicide attempt (1.49 [1.21-1.85]). Adolescents in South Africa are experiencing a multiple burden of risk. Health promotion strategies targeting adolescent mental health and risk behaviours need to be developed and implemented in a timely and comprehensive manner.

Nurses must have adequate knowledge to manage the complexities of urinary incontinence. Nursing students are the nurses of the future, yet little is known about urinary incontinence education in undergraduate nursing programs. The aim of this study was (a) to assess the knowledge and attitudes of urinary incontinence held by undergraduate nursing students in China and (b) to explore the relationship between knowledge, attitudes and socio-demographic characteristics. A cross-sectional survey using cluster random sampling. Undergraduate departments of Nursing within the Faculty of Health Sciences at six Universities, located in different areas of China. A random selection of 6 faculties with a total of 1313 full time undergraduate nursing students completed the survey. Self-reported data were collected using two validated questionnaires, the Urinary Incontinence Knowledge Scale and the Urinary Incontinence Attitude Scale, to access students' knowledge and attitudes toward urinary incontinence. Overall urinary incontinence knowledge was poor (49.9%, 15.0/30) and attitudes about urinary incontinence were generally positive (71.7%, 43.0/60). A high level of interest in learning more about urinary incontinence was found. There was a weak correlation between urinary incontinence knowledge and attitudes (r=0.135, p<0.01). There was also a significant positive correlation between urinary incontinence knowledge and attitudes and nursing students' year of study, urinary incontinence education and training, and formal clinical practicum experience in urology (p<0.05). Chinese nursing students showed poor urinary incontinence knowledge but generally positive attitudes toward urinary incontinence. This study suggests there is a need to examine urinary incontinence content throughout undergraduate nursing curricula in China. Copyright © 2016 Elsevier Ltd. All rights reserved.

Use of ultrasound guidance for Central Venous Catheter insertion has been associated with decreased complications and increased success rates. Previous reports show low rates of use among physicians. Evaluation of the frequency of Ultrasound Guidance use for Central Venous Catheter insertion among residents at a teaching institution. A cross sectional electronic survey of resident physicians at a tertiary care teaching hospital was conducted to evaluate use of Ultrasound Guidance for Central Venous Catheterization. Assessment included self reported frequency of ultrasound guidance use, and volume of central venous catheter placement. Attitudes toward the use of ultrasound were assessed using Likert scales. There is a high rate. over 90%, of ultrasound guidance use for Internal Jugular central venous catheters among residents. The majority of residents use sterile real-time imaging with a single operator with a reported success rate greater then 80%. Resident use of ultrasound guidance for Internal Jugular central venous catheter insertion can be much higher than previously reported in the literature.

Vertically stabilized elongated cross-section tokamak

DOEpatents

Sheffield, George V.

1977-01-01

This invention provides a vertically stabilized, non-circular (minor) cross-section, toroidal plasma column characterized by an external separatrix. To this end, a specific poloidal coil means is added outside a toroidal plasma column containing an endless plasma current in a tokamak to produce a rectangular cross-section plasma column along the equilibrium axis of the plasma column. By elongating the spacing between the poloidal coil means the plasma cross-section is vertically elongated, while maintaining vertical stability, efficiently to increase the poloidal flux in linear proportion to the plasma cross-section height to achieve a much greater plasma volume than could be achieved with the heretofore known round cross-section plasma columns. Also, vertical stability is enhanced over an elliptical cross-section plasma column, and poloidal magnetic divertors are achieved.

The national tuberculosis strain typing service (TB-STS) was introduced in England in 2010. The TB-STS involves MIRU-VNTR typing of isolates from all TB patients for the prospective identification, reporting and investigation of TB strain typing clusters. As part of a mixed-method evaluation, we report on a repeated cross-sectional survey to illustrate the challenges surrounding the evaluation of a complex national public health intervention. An online initial and follow-up questionnaire survey assessed the knowledge, attitudes and practices of public health staff, physicians and nurses working in TB control in November 2010 and March 2012. It included questions on the implementation, experience and uptake of the TB-STS. Participants that responded to both surveys were included in the analysis. 248 participants responded to the initial survey and 137 of these responded to the follow-up survey (56% retention). Knowledge: A significant increase in knowledge was observed, including a rise in the proportion of respondents who had received training (28.6% to 67.9%, p = 0.003), and the self-rated knowledge of how to use strain typing had improved ('no knowledge' decreased from 43.2% to 27.4%). Attitudes: The majority of respondents found strain typing useful; the proportion that reported strain typing to be useful was similar across the two surveys (95.7% to 94.7%, p = 0.67). Practices: There were significant increases between the initial and follow-up surveys in the number of respondents who reported using strain typing (57.0% to 80.5%, p < 0.001) and the proportion of time health protection staff spent on investigating TB (2.74% to 7.08%, p = 0.04). Evaluation of a complex public health intervention is challenging. In this example, the immediate national roll-out of the TB-STS meant that a controlled survey design was not possible. This study informs the future development of the TB-STS by identifying the need for training to reach wider professional groups, and argues

There is increasing evidence to suggest an association between sleep and diet. The aim of the present study was to examine the association between sleep duration and fruit/vegetable (FV) intakes and their associated biomarkers in UK adults. Cross-sectional. Data from The National Diet and Nutrition Survey. 1612 adults aged 19-65 years were included, pregnant/breastfeeding women were excluded from the analyses. Sleep duration was assessed by self-report, and diet was assessed by 4-day food diaries, disaggregation of foods containing FV into their components was conducted to determine total FV intakes. Sleep duration was divided into: short (<7 hours/day), reference (7-8 hours/day) and long (>8 hours/day) sleep periods. Multiple regression adjusting for confounders was used for analyses where sleep duration was the exposure and FV intakes and their associated biomarkers were the outcomes. Restricted cubic spline models were developed to explore potential non-linear associations. In adjusted models, long sleepers (LS) consumed on average 28 (95% CI -50 to -6, p=0.01) g/day less of total FV compared to reference sleepers (RS), whereas short sleepers (SS) consumed 24 g/day less (95% CI -42 to -6, p=0.006) and had lower levels of FV biomarkers (total carotenoids, β-carotene and lycopene) compared to RS. Restricted cubic spline models showed that the association between sleep duration and FV intakes was non-linear (p<0.001) with RS having the highest intakes compared to SS and LS. The associations between sleep duration and plasma total carotenoids (p=0.0035), plasma vitamin C (p=0.009) and lycopene (p<0.001) were non-linear with RS having the highest levels. These findings show a link between sleep duration and FV consumption. This may have important implications for lifestyle and behavioural change policy. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Objectives Provision of National Health Service (NHS) specialist chronic fatigue syndrome or myalgic encephalomyelitis (CFS/ME) services in England has been deemed patchy and inconsistent. Our objective was to explore variation in the provision of NHS specialist CFS/ME services and to investigate whether access is related to measures of deprivation and inequality. Design Survey of all CFS/ME clinical teams in England, plus cross-sectional data from a subset of teams. Setting Secondary care. Outcome measures We used clinic activity data from CFS/ME clinical teams in England to describe provision of specialist CFS/ME services (referral, assessment and diagnosis rates per 1000 adults per year) during 2008–2011 according to Primary Care Trust (PCT) population estimates, and to investigate whether use of services was related to PCT-level measures of deprivation and inequality. We used postcode data from seven services to investigate variation in provision by deprivation. Results Clinic activity data were obtained from 93.9% (46/49) of clinical teams in England which between them received referrals from 84.9% (129/152) of PCTs. 12 PCTs, covering a population of 2.08 million adults, provided no specialist CFS/ME service. There was a six-fold variation in referral and assessment rates between services which could not be explained by PCT-level measures of deprivation and inequality. The median assessment rate in 2010 was 0.25 (IQR 0.17, 0.35) per 1000 adults per year. 91.9% (IQR 76.5%, 100.0%) of adults assessed were diagnosed with CFS/ME. Postcode data from seven clinical teams showed that assessment rates were equal across deprivation quartiles for four teams but were 40–50% lower in the most deprived compared with the most affluent areas for three teams. Conclusions Two million adults in England do not have access to a specialist CFS/ME service. In some areas which do have a specialist service, access is inequitable. This inequity may worsen with the impending

Human immunodeficiency virus (HIV) self-testing presents an empowering alternative to facility-based testing for reaching undiagnosed HIV infected individuals, but is not currently available in Canada. We surveyed stakeholders (clinical providers, public health professionals, researchers) engaged in HIV testing initiatives nationwide to identify the concerns, opportunities and challenges to implementing HIV self-testing in Canada. An online cross-sectional survey was disseminated by the Canadian Institutes of Health Research Centre for REACH 2.0 National HIV & sexually transmitted and blood borne infections working group to stakeholders nationwide, with a target sample size of 200. Quantitative and qualitative data were analyzed using a mixed-methods, respondent-informed approach, to inform subsequent HIV self-testing in a country where self-testing is not yet accessible. A total of 183 responses were received. A majority (70.7%) (128/181) felt that self-testing was a necessary investment to reach the undiagnosed. 64.6% (117/181) felt that self-tests should be made available to their clients and 71.5% (128/179) of respondents agreed that self-test instructions required improvements. However, 50% (90/180) felt that self-testing will pose an economic challenge to current HIV testing models. Regardless, 21% urged for timely action and availability of HIV self-tests. Thematic analyses reflected the following concerns: (a) need for affordable self-tests, (b) need for expedited, customized, and accessible linkages to counselling, (c) concern for patients to cope with positive self-test results, (d) accuracy of self-tests to detect acute HIV and (e) liability in the context of non-disclosure. Stakeholders agreed to the provision of an option of HIV self-testing to reach the undiagnosed individuals. Concerns regarding costs and accuracy of self-tests, expedited linkages to counselling, and integration of self-test within prevailing HIV testing models, will need to be

Child mortality in the Democratic Republic of Congo: cross-sectional evidence of the effect of geographic location and prolonged conflict from a national household survey

PubMed Central

2014-01-01

Background The child mortality rate is a good indicator of development. High levels of infectious diseases and high child mortality make the Democratic Republic of Congo (DRC) one of the most challenging environments for health development in Sub-Saharan Africa (SSA). Recent conflicts in the eastern part of the country and bad governance have compounded the problem. This study aimed to examine province-level geographic variation in under-five mortality (U5M), accounting for individual- and household-level risk factors including environmental factors such as conflict. Methods Our analysis used the nationally representative cross-sectional household sample of 8,992 children under five in the 2007 DRC Demographic and Health Survey. In the survey year, 1,005 deaths among this group were observed. Information on U5M was aggregated to the 11 provinces, and a Bayesian geo-additive discrete-time survival mixed model was used to map the geographic distribution of under-five mortality rates (U5MRs) at the province level, accounting for observable and unobservable risk factors. Results The overall U5MR was 159 per 1,000 live births. Significant associations with risk of U5M were found for < 24 month birth interval [posterior odds ratio and 95% credible region: 1.14 (1.04, 1.26)], home birth [1.13 (1.01, 1.27)] and living with a single mother [1.16 (1.03, 1.33)]. Striking variation was also noted in the risk of U5M by province of residence, with the highest risk in Kasaï-Oriental, a non-conflict area of the DRC, and the lowest in the conflict area of North Kivu. Conclusion This study reveals clear geographic patterns in rates of U5M in the DRC and shows the potential role of individual child, household and environmental factors, which are unexplained by the ongoing conflict. The displacement of mothers to safer areas may explain the lower U5MR observed at the epicentre of the conflict in North Kivu, compared with rates in conflict-free areas. Overall, the U5M maps point

Since the comprehensive peace agreement was signed in 2005, institutionalization of immunization services in South Sudan remained a priority. Routine administrative reporting systems were established and showed that national coverage rates for DTP-3 rose from 20% in 2002 to 80% in 2011. This survey was conducted as part of an overall review of progress in implementation of the first EPI Multi-Year Plan for South Sudan 2007-2011. This report provides maiden community coverage estimates for immunization. A cross sectional community survey was conducted between January and May 2012. Ten cluster surveys were conducted to generate state-specific coverage estimates. The WHO 30x7 cluster sampling method was employed. Data was collected using pre-tested, interviewer guided, structured questionnaires through house to house visits. The fully immunized children were 7.3%. Coverage for specific antigens were; BCG (28.3%), DTP-1(25.9%), DTP-3 (22.0%), Measles (16.8%). The drop-out rate between the first and third doses of DTP was 21.3%. Immunization coverage estimates based on card and history were higher, at 45.7% for DTP-3, 45.8% for MCV and 32.2% for full immunization. Majority of immunizations (80.8%) were received at health facilities compared to community service points (19.2%). The major reason for missed immunizations was inadequate information (41.1%). The proportion of card-verified, fully vaccinated among children aged 12-23 months is very low at 7.3%. Future efforts to improve vaccination quality and coverage should prioritize training of vaccinators and program communication to levels equivalent or higher than investments in EPI cold chain systems since 2007.

Introduction Since the comprehensive peace agreement was signed in 2005, institutionalization of immunization services in South Sudan remained a priority. Routine administrative reporting systems were established and showed that national coverage rates for DTP-3 rose from 20% in 2002 to 80% in 2011. This survey was conducted as part of an overall review of progress in implementation of the first EPI Multi-Year Plan for South Sudan 2007-2011. This report provides maiden community coverage estimates for immunization. Methods A cross sectional community survey was conducted between January and May 2012. Ten cluster surveys were conducted to generate state-specific coverage estimates. The WHO 30x7 cluster sampling method was employed. Data was collected using pre-tested, interviewer guided, structured questionnaires through house to house visits. Results The fully immunized children were 7.3%. Coverage for specific antigens were; BCG (28.3%), DTP-1(25.9%), DTP-3 (22.0%), Measles (16.8%). The drop-out rate between the first and third doses of DTP was 21.3%. Immunization coverage estimates based on card and history were higher, at 45.7% for DTP-3, 45.8% for MCV and 32.2% for full immunization. Majority of immunizations (80.8%) were received at health facilities compared to community service points (19.2%). The major reason for missed immunizations was inadequate information (41.1%). Conclusion The proportion of card-verified, fully vaccinated among children aged 12-23 months is very low at 7.3%. Future efforts to improve vaccination quality and coverage should prioritize training of vaccinators and program communication to levels equivalent or higher than investments in EPI cold chain systems since 2007.

Water, sanitation, and hygiene (WaSH) in schools contributes to better health and educational outcomes among school-aged children. In 2012, UNICEF Nicaragua and partners conducted a cross-sectional survey of WaSH in 526 schools in 12 low socio-economic status municipalities in Nicaragua. The survey gathered information on: school characteristics; teacher and community participation; water and sanitation infrastructure; and hygiene education and habits. Survey results were analyzed for associations between variables. WaSH coverage was significantly higher in urban than rural areas. Presence of drinking water infrastructure (43%) was lower than sanitation infrastructure (64%). Eighty-one percent of schools had no hand washing stations and 74% of schools lacked soap. Sanitation facilities were not in use at 28% of schools with sanitation infrastructure and 26% of schools with water infrastructure had non-functional systems. Only 8% of schools had budgets to purchase toilet-cleaning supplies and 75% obtained supplies from students' families. This study generates transferable WaSH sector learnings and new insights from monitoring data. Results can be used by donors, service providers, and policy makers to better target resources in Nicaraguan schools.

Attitudes towards mental illness in Malawi: a cross-sectional survey

PubMed Central

2012-01-01

Background Stigma and discrimination associated with mental illness are strongly linked to suffering, disability and poverty. In order to protect the rights of those with mental disorders and to sensitively develop services, it is vital to gain a more accurate understanding of the frequency and nature of stigma against people with mental illness. Little research about this issue has been conducted in Sub- Saharan Africa. Our study aimed to describe levels of stigma in Malawi. Methods A cross-sectional survey of patients and carers attending mental health and non-mental health related clinics in a general hospital in Blantyre, Malawi. Participants were interviewed using an adapted version of the questionnaire developed for the “World Psychiatric Association Program to Reduce Stigma and Discrimination Because of Schizophrenia”. Results 210 participants participated in our study. Most attributed mental disorder to alcohol and illicit drug abuse (95.7%). This was closely followed by brain disease (92.8%), spirit possession (82.8%) and psychological trauma (76.1%). There were some associations found between demographic variables and single question responses, however no consistent trends were observed in stigmatising beliefs. These results should be interpreted with caution and in the context of existing research. Contrary to the international literature, having direct personal experience of mental illness seemed to have no positive effect on stigmatising beliefs in our sample. Conclusions Our study contributes to an emerging picture that individuals in Sub-Saharan Africa most commonly attribute mental illness to alcohol/ illicit drug use and spirit possession. Our work adds weight to the argument that stigma towards mental illness is an important global health and human rights issue. PMID:22823941

In this paper experiments are reported on annihilation and scattering of antiprotons in H{sub 2}O , D{sub 2}O, and O{sub 2}. From the data measured it is possible to obtain an antiproton-proton and an antiproton-deuteron cross section at 457 Mev (lab). Further analysis gives the p-p and p-n cross sections as 104 mb for the p-p reaction cross section and 113 mb for the p-n reaction cross section. The respective annihilation cross sections are 89 and 74 mb. The Glauber correction necessary in order to pass from the p-d to the p-n cross section by subtraction of the p-p cross section is unfortunately large and somewhat uncertain. The data are compared with the p-p and p-n cross sections and with other results on p-p collisions.

In this study, we determined the factors influencing parenting efficacy of Asian immigrant, first-time mothers. The research design was a cross-sectional, correlational study. The study included 125 first-time mothers who immigrated and married Korean men, and were living in Korea. Data were collected using translated questionnaires, and analyzed for descriptive statistics, Pearson correlation, and multiple regression analysis. The major finding was that the parenting efficacy of immigrant women was influenced by childcare support from their husbands, maternal identity, and original nationality. The findings suggest that customized programs be developed and used to enhance parenting efficacy for Asian immigrant, first-time mothers. In developing such programs, the advantages of maternal identity, social support from the husband, and women's cultural context should be considered. © 2017 John Wiley & Sons Australia, Ltd.

Ownership and use of mobile phones among health workers, caregivers of sick children and adult patients in Kenya: cross-sectional national survey

PubMed Central

2013-01-01

Background The rapid growth in mobile phone penetration and use of Short Message Service (SMS) has been seen as a potential solution to improve medical and public health practice in Africa. Several studies have shown effectiveness of SMS interventions to improve health workers’ practices, patients’ adherence to medications and availability of health facility commodities. To inform policy makers about the feasibility of facility-based SMS interventions, the coverage data on mobile phone ownership and SMS use among health workers and patients are needed. Methods In 2012, a national, cross-sectional, cluster sample survey was undertaken at 172 public health facilities in Kenya. Outpatient health workers and caregivers of sick children and adult patients were interviewed. The main outcomes were personal ownership of mobile phones and use of SMS among phone owners. The predictors analysis examined factors influencing phone ownership and SMS use. Results The analysis included 219 health workers and 1,177 patients’ respondents (767 caregivers and 410 adult patients). All health workers possessed personal mobile phones and 98.6% used SMS. Among patients’ respondents, 61.2% owned phones and 71.4% of phone owners used SMS. The phone ownership and SMS use was similar between caregivers of sick children and adult patients. The respondents who were male, more educated, literate and living in urban area were significantly more likely to own the phone and use SMS. The youngest respondents were less likely to own phones, however when the phones were owned, younger age groups were more likely to use SMS. Respondents living in wealthier areas were more likely to own phones; however when phones are owned no significant association between the poverty and SMS use was observed. Conclusions Mobile phone ownership and SMS use is ubiquitous among Kenyan health workers in the public sector. Among patients they serve the coverage in phone ownership and SMS use is lower and

Infrared absorption spectra for pure and He broadened propane have been recorded in the far-IR region (650-1300 cm-1) at the Canadian Light Source (CLS) facility using either the synchrotron or internal glowbar source depending on the required resolution. The measurements were made for 4 temperatures in the range 202-292 K and for 3 pressures of He broadening gas up to 100 Torr. Infrared absorption cross sections are derived from the spectra and the integrated cross sections are within 10 % of the corresponding values from the Pacific Northwest National Laboratory (PNNL) for all temperatures and pressures.

(1) To analyze the prevalence of Intimate Partner Violence by types. (2) To examine the relationship between sociodemographic characteristics and Intimate Partner Violence. Cross-sectional study using a self-administered questionnaire. Primary Healthcare centers in Spain. 10,322 women (18-70 years) attending Primary Healthcare centers. A compound index was calculated based on frequency, types, and duration of Intimate Partner Violence. Multivariable adjusted logistic regression models were used to identify the sociodemographic factors, which were independently associated with each Intimate Partner Violence category. The prevalence of Intimate Partner Violence was 24.8%. For the physical only category, no differences were observed regarding education or employment status, and women with the highest income have less risk. For the psychological only category, no differences were observed according to the income level. The risk increases as the education level decreases, and the greatest frequency of only psychological Intimate Partner Violence was observed in women who were unemployed or students. For both the physical and psychological category of Intimate Partner Violence, a clear risk increase is observed as income and education levels decrease. Retired women showed the highest frequency of this violence category. The results show that Intimate Partner Violence affects women of all social strata, but the frequency and Intimate Partner Violence category will vary according to the socio-economic.

adherence to medication. A questionnaire-based cross-sectional survey of 138 carers across 16 European countries. Interpretation of results was based on a descriptive comparison of responses. Carers recognized the importance of medication to help patients get better (76%) and improve their quality of life (76%) and relationships (74%). Sixty-seven per cent believed medication damages general health. Sixty-five per cent reported that treatment adherence was a burden for patients. Thirty-eight per cent indicated that it was a daily struggle to get patients to take their medication. Fifty per cent perceived that medication administered every few weeks rather than daily was quite/very important. Ninety-three per cent agreed on the importance of family support to boost adherence, with education and information deemed important for families and patients. Carers rely less on the patient themselves when assessing adherence than psychiatrists. The burden faced by carers and patients in taking medication provides an opportunity for healthcare professionals to provide support in a multidisciplinary 'team' involving psychiatrists, nurses and carers. © 2015 The Authors.

Eating patterns of Turkish adolescents: a cross-sectional survey

PubMed Central

2010-01-01

Background Adolescence is a crucial period for development of dietary behaviors that continue into adulthood and influence the risk of chronic diseases later in life. The aim of this study was to determine the eating patterns of adolescents' and their compliance with the Food Guide Pyramid. Methods 625 students, aged between 11-15 years, from an elementary school in Istanbul, Turkey were enrolled in this cross-sectional survey. A questionnaire of eating patterns (QEP) was administered to all participants. QEP is consisted of questions assessing the knowledge and behaviors on healthy eating, factors affecting food choice, physical activity status and demographical variables. Height and weight of all participants were measured. Physical activity status was determined by questioning about participation in regular sport activities, how much time spent watching TV, playing computer games or doing homework. Results The mean age of the participants was 12.15 ± 1.15 and 50.5% were female. According to body mass index (BMI) percentiles, 8.3% (52) were obese and 10.2% were overweight. 51% had breakfast every day and only 1.9% met all the recommendations of the Food Guide Pyramid. Among the participants, 31% have fast food at least once every day and 60.8% skip meals. When participants were asked to rate the factors effecting their food choice according to a 10 point Likert scale, the highest mean scores (high impact on food choice) were for the factors; family, health, body perception, teachers and friends; 7.5 ± 3.1, 7.4 ± 3.1, 6.1 ± 3.2, 4.8 ± 3.3 and 4.2 ± 3.0 respectively. Total mean time spent on all passive activities (TV, computer, reading homework etc) per day was 9.8 ± 4.7 hours. Conclusions In this study we have demonstrated that, adolescents do not have healthy eating patterns. Educational interventions should be planned to decrease the health risks attributable to their eating behaviors. PMID:21167070

Cross-sectional prevalence survey of intimate partner violence perpetration and victimization in Canadian military personnel

PubMed Central

2013-01-01

Background Intimate partner violence (IPV) is prevalent and is associated with a broad range of adverse consequences. In military organizations, IPV may have special implications, such as the potential of service-related mental disorders to trigger IPV. However, the Canadian Armed Forces (CAF) have limited data to guide their prevention and control efforts. Methods Self-reported IPV perpetration, victimization, and their correlates were assessed on a cross-sectional survey of a stratified random sample of currently-serving Canadian Regular Forces personnel (N = 2157). The four primary outcomes were perpetration or victimization of any physical and/or sexual or emotional and/or financial IPV over the lifespan of the current relationship. Results Among the 81% of the population in a current relationship, perpetration of any physical and/or sexual IPV was reported in 9%; victimization was reported in 15%. Any emotional and/or financial abuse was reported by 19% (perpetration) and 22% (victimization). Less physically injurious forms of abuse predominated. Logistic regression modelling showed that relationship dissatisfaction was independently associated with all four outcomes (OR range = 2.3 to 3.7). Probable depression was associated with all outcomes except physical and/or sexual IPV victimization (OR range = 2.5 – 2.7). PTSD symptoms were only associated with physical and/or sexual IPV perpetration (OR = 3.2, CI = 1.4 to 7.9). High-risk drinking was associated with emotional and/or financial abuse. Risk of IPV was lowest in those who had recent deployment experience; remote deployment experience (vs. never having deployed) was an independent risk factor for all IPV outcomes (OR range = 2.0 – 3.4). Conclusions IPV affects an important minority of military families; less severe cases predominate. Mental disorders, high-risk drinking, relationship dissatisfaction, and remote deployment were independently associated with abuse outcomes. The

An improved technique is presented for employing the 2.3m spectrometer to measure total ionization cross sections, Q sub ion, for positrons incident on He. The new ionization cross section agree with the values reported earlier. Estimates are also presented of total elastic scattering cross section, Q sub el, obtained by subtracting from total scattering cross sections, Q sub tot, reported in the literature, the Q sub ion and Q sub Ps (total positronium formation cross sections) and total excitation cross sections, Q sub ex, published by another researcher. The Q sub ion and Q sub el measured with the 3m high resolution time-of-flight spectrometer for 54.9eV positrons are in accord with the results from the 2.3m spectrometer. The ionization cross sections are in fair agreement with theory tending for the most part to be higher, especially at 76.3 and 88.5eV. The elastic cross section agree quite well with theory to the vicinity of 50eV, but at 60eV and above the experimental elastic cross sections climb to and remain at about 0.30 pi a sub o sq while the theoretical values steadily decrease.

While the majority of veteran suicides involve firearms, no contemporary data describing firearm ownership among US veterans are available. This study uses survey data to describe the prevalence of firearm ownership among a nationally representative sample of veterans, as well as veterans' reasons for firearm ownership. A cross-sectional, nationally representative web-based survey conducted in 2015. Nearly half of all veterans own one or more firearms (44.9%, 95% CI 41.3-48.6%), with male veterans more commonly owning firearms than do female veterans (47.2%, 95% CI 43.4-51.0% versus 24.4%, 95%CI 15.6-36.1%). Most veteran firearm owners own both handguns and long guns (56.5%, 95% CI 51.1-61.8%); a majority cite protection as a primary reason for firearm ownership (63.1%, 95% CI 58.2-67.8%). The current study is the first to provide detailed, nationally representative information about firearm ownership among U.S. veterans. Better understanding firearm ownership among veterans can usefully inform ongoing suicide prevention efforts aiming to facilitate lethal means safety among vulnerable veterans during at-risk periods.

Reducing cross-sectional data using a genetic algorithm method and effects on cross-section geometry and steady-flow profiles

The effects of reduced cross-sectional data points on steady-flow profiles were also determined. Thirty-five cross sections of the original steady-flow model of the Kootenai River were used. These two methods were tested for all cross sections with each cross section resolution reduced to 10, 20 and 30 data points, that is, six tests were completed for each of the thirty-five cross sections. Generally, differences from the original water-surface elevation were smaller as the number of data points in reduced cross sections increased, but this was not always the case, especially in the braided reach. Differences were smaller for reduced cross sections developed by the genetic algorithm method than the standard algorithm method.

This study evaluated the cross-sectional and longitudinal associations of functional and health status with institutional care, and examined determinants of institutional care use over time. Data of this study were obtained from the Survey of Health and Living Status of the Elderly in Taiwan (SHLSET), which was launched in 1989 and involved a nationally representative sample of nearly-old and old Taiwanese. The baseline data in this present study were collected in 1999, and followed in 2003 and 2007. Participants with institutional care use had a higher activities of daily living (ADL) score, more self-reported diseases and poorer self-reported health status than participants without institutional care use (all P<0.05). Cross-sectional analysis showed that a higher ADL score, having heart diseases and having a stroke were positively associated with institutional care use (P<0.05); whereas the number of self-reported diseases and poor self-reported health status were not associated with institutional care use. Longitudinal analysis showed that increased ADL scores and the number of self-reported diseases over 4- and 8 years were associated with an increased likelihood of subsequent institutional care use (all P<0.05). Worsening health status over 4 years was associated with an increased likelihood of subsequent institutional care use, but this association did not exist over 8 years. Only ADL and ADL deterioration over time are cross-sectionally and longitudinally associated with increased institutional care use. Declining functional status is a major determinant of institutional care use for Taiwanese aged over 53 years. © 2012 Japan Geriatrics Society.

Objective Transgender individuals are at increased risk for HIV infection around the world, yet few studies have focused on transgender individuals in China. We conducted an online cross-sectional survey of men who have sex with men (MSM) and transgender individuals to examine sociodemographics, intimate partner violence (IPV) and sexual behaviours in China. Methods We recruited participants (born biologically male, ≥16 years old, ever engaged in anal sex with men and agreed to provide cell phone number) from three web platforms in 2014. Data on sociodemographics, IPV and sexual behaviours were collected. Logistic regressions were performed to compare the differences between transgender individuals and non-transgender MSM. Results Overall, 1424 eligible participants completed our online survey. Of these participants, 61 (4.3%) were transgender individuals, including 28 (2.0%) identifying as women and 33 (2.3%) identifying as transgender. Compared with MSM, transgender individuals were more likely to have experienced IPV and sexual violence (economic abuse, physical abuse, threat to harm loved ones, threat to ‘out’, forced sex). In addition, transgender individuals were more likely to have engaged in commercial sex (21.3% vs 5.1%, aOR 4.80, 95% CI 2.43 to 9.51) and group sex (26.2% vs 9.2%, aOR 3.47, 95% CI 1.58 to 6.48) in the last 12 months. Conclusions Our study is consistent with the emerging literature demonstrating increased sexual risk behaviours and high levels of IPV among transgender individuals. Future research should further investigate transgender individuals’ experiences of IPV and explore ways to promote disclosure of gender identity to healthcare providers. Furthermore, transgender research in China should be expanded independently of MSM research. PMID:27052037

Schistosomiasis and soil-transmitted helminthiasis (STHs) are target neglected tropical diseases (NTDs) of preventive chemotherapy, but the control and elimination of these diseases have been impeded due to resource constraints. Few reports have described study protocol to draw on when conducting a nationwide survey. We present a detailed methodological description of the integrated mapping of schistosomiasis and STHs on the basis of our experiences, hoping that this protocol can be applied to future surveys in similar settings. In addition to determining the ecological zones requiring mass drug administration interventions, we aim to provide precise estimates of the prevalence of these diseases. A school-based cross-sectional design will be applied for the nationwide survey across Sudan. The survey is designed to cover all districts in every state. We have divided each district into 3 different ecological zones depending on proximity to bodies of water. We will employ a probability-proportional-to-size sampling method for schools and systematic sampling for student selection to provide adequate data regarding the prevalence for schistosomiasis and STHs in Sudan at the state level. A total of 108,660 students will be selected from 1811 schools across Sudan. After the survey is completed, 391 ecological zones will be mapped out. To carry out the survey, 655 staff members were recruited. The feces and urine samples are microscopically examined by the Kato-Katz method and the sediment smears for helminth eggs respectively. For quality control, a minimum of 10% of the slides will be rechecked by the federal supervisors in each state and also 5% of the smears are validated again within one day by independent supervisors. This nationwide mapping is expected to generate important epidemiological information and indicators about schistosomiasis and STHs that will be useful for monitoring and evaluating the control program. The mapping data will also be used for overviewing

Augmented Cross-Sectional Studies with Abbreviated Follow-up for Estimating HIV Incidence

PubMed Central

Claggett, B.; Lagakos, S.W.; Wang, R.

2011-01-01

Summary Cross-sectional HIV incidence estimation based on a sensitive and less-sensitive test offers great advantages over the traditional cohort study. However, its use has been limited due to concerns about the false negative rate of the less-sensitive test, reflecting the phenomenon that some subjects may remain negative permanently on the less-sensitive test. Wang and Lagakos (2010) propose an augmented cross-sectional design which provides one way to estimate the size of the infected population who remain negative permanently and subsequently incorporate this information in the cross-sectional incidence estimator. In an augmented cross-sectional study, subjects who test negative on the less-sensitive test in the cross-sectional survey are followed forward for transition into the nonrecent state, at which time they would test positive on the less-sensitive test. However, considerable uncertainty exists regarding the appropriate length of follow-up and the size of the infected population who remain nonreactive permanently to the less-sensitive test. In this paper, we assess the impact of varying follow-up time on the resulting incidence estimators from an augmented cross-sectional study, evaluate the robustness of cross-sectional estimators to assumptions about the existence and the size of the subpopulation who will remain negative permanently, and propose a new estimator based on abbreviated follow-up time (AF). Compared to the original estimator from an augmented cross-sectional study, the AF Estimator allows shorter follow-up time and does not require estimation of the mean window period, defined as the average time between detectability of HIV infection with the sensitive and less-sensitive tests. It is shown to perform well in a wide range of settings. We discuss when the AF Estimator would be expected to perform well and offer design considerations for an augmented cross-sectional study with abbreviated follow-up. PMID:21668904

Recently we applied the molecular convergent close-coupling (CCC) method to electron scattering from molecular hydrogen H2. Convergence of the major integrated cross sections has been explicitly demonstrated in the fixed-nuclei approximation by increasing the number of H2 target states in the close-coupling expansion from 9 to 491. The calculations have been performed using a projectile partial wave expansion with maximum orbital angular momentum Lmax = 8 and total orbital angular momentum projections | M | <= 8 . Coupling to the ionization continuum is modeled via a large pseudo state expansion, which we found is required to obtain reliable elastic and excitation cross sections. Here we present benchmark elastic, single-ionization, electronic excitation and total integrated cross sections over a broad energy range (0.1 to 300 eV) and compare with available experiment and previous calculations.

Objectives To determine the prevalence of antibodies to hepatitis B core antigen, hepatitis C virus, and HIV in entrants to Irish prisons and to examine risk factors for infection. Design Cross sectional, anonymous survey, with self completed risk factor questionnaire and oral fluid specimen for antibody testing. Setting Five of seven committal prisons in the Republic of Ireland. Participants 607 of the 718 consecutive prison entrants from 6 April to 1 May 1999. Main outcome measures Prevalence of antibodies to hepatitis B core antigen, hepatitis C virus, and HIV in prison entrants, and self reported risk factor status. Results Prevalence of antibodies to hepatitis B core antigen was 37/596 (6%; 95% confidence interval 4% to 9%), to hepatitis C virus was 130/596 (22%; 19% to 25%), and to HIV was 12/596 (2%; 1% to 4%). A third of the respondents had never previously been in prison; these had the lowest prevalence of antibodies to hepatitis B core antigen (4/197, 2%), to hepatitis C (6/197, 3%), and to HIV (0/197). In total 29% of respondents (173/593) reported ever injecting drugs, but only 7% (14/197) of those entering prison for the first time reported doing so compared with 40% (157/394) of those previously in prison. Use of injected drugs was the most important predictor of antibodies to hepatitis B core antigen and hepatitis C virus. Conclusions Use of injected drugs and infection with hepatitis C virus are endemic in Irish prisons. A third of prison entrants were committed to prison for the first time. Only a small number of first time entrants were infected with one or more of the viruses. These findings confirm the need for increased infection control and harm reduction measures in Irish prisons. What is already known on this topicHigh rates of using injected drugs, initiation of use of injected drugs, and sharing injecting equipment occur in Irish prisonsInjecting drug users have high rates of infection with hepatitis B and C viruses, and hepatitis C is

Malaria is often a major health problem in countries undergoing war or conflict owing to breakdown of health systems, displacement of vulnerable populations, and the increased risk of epidemics. After 23 years of conflict, malaria has become prevalent in many rural areas of Afghanistan. From 1993 to the present, a network of non-governmental organizations, co-ordinated by HealthNet International, has operated a programme of bednet sales and re-treatment in lowland areas. To examine whether a strategy based on insecticide-treated nets (ITN) is a viable public health solution to malaria, communities were given the opportunity to buy nets and then monitored to determine population coverage and disease control impact. This was carried out using two contrasting methods: cross-sectional surveys and passive surveillance from clinics using a case-control design. Nets were purchased by 59% of families. Cross-sectional surveys demonstrated a 59% reduction in the risk of Plasmodium falciparum infection among ITN users compared with non-users (OR 0.41; 95% CI 0.25-0.66). The passive surveillance method showed a comparable reduction in the risk of symptomatic P. falciparum malaria among ITN users (OR 0.31; 95% CI 0.21-0.47). The cross-sectional method showed a 50% reduction in risk of P. vivax infection in ITN users compared with non-users (OR 0.50; 95% CI 0.17-1.49) but this effect was not statistically significant. The passive surveillance method showed a 25% reduction in the risk of symptomatic P. vivax malaria (OR 0.75; 95% CI 0.66-0.85). ITN appeared to be less effective against P. vivax because of relapsing infections; hence an effect took more than one season to become apparent. Passive surveillance was cheaper to perform and gave results consistent with cross-sectional surveys. Untreated nets provided some protection. Data on socioeconomic status, a potential confounding factor, was not collected. However, at the time of net sales, there was no difference in malaria

Nucleon-Nucleon Total Cross Section

The total proton-proton and neutron-proton cross sections currently used in the transport code HZETRN show significant disagreement with experiment in the GeV and EeV energy ranges. The GeV range is near the region of maximum cosmic ray intensity. It is therefore important to correct these cross sections, so that predictions of space radiation environments will be accurate. Parameterizations of nucleon-nucleon total cross sections are developed which are accurate over the entire energy range of the cosmic ray spectrum.

Rehabilitation following medical conditions is largely offered as in-patient service in Germany. Foreign-national residents use rehabilitative services less often than Germans and attain less favourable treatment outcomes. These differences are independent of demographic, socioeconomic and health characteristics. Satisfaction with different aspects of rehabilitative care presumably affects the effectiveness of rehabilitative services. We compared the degree of satisfaction with different domains of the rehabilitative care process between Germans and non-German nationals residing in Germany. We used data from a cross-sectional rehabilitation patient survey annually conducted by the German Statutory Pension Insurance Scheme. The sample comprises 274 513 individuals undergoing medical rehabilitation in 642 hospitals during the years 2007-2011. Participants rated their satisfaction with different domains of rehabilitation on multi-item scales. We dichotomised each scale to low/moderate and high satisfaction. For each domain, a multilevel adjusted logistic regression analysis was conducted to examine differences in the levels of satisfaction between German and non-German nationals. Average marginal effects (AMEs) and 99.5% CI were computed as effect estimates. AMEs represent differences in the probability for the occurrence of the outcome. Turkish nationals had a higher probability for being less satisfied with most aspects of their rehabilitation, with AMEs ranging between 0.05 (99.5% CI 0.00 to 0.09) for 'satisfaction with psychological care' and 0.11 (99.5% CI 0.08 to 0.14) for 'satisfaction with treatments during rehabilitation'. Patients from former Yugoslavia and from Portugal/Spain/Italy/Greece were as satisfied as Germans with most aspects of their rehabilitation. Turkish nationals are less satisfied with their rehabilitative care than other population groups. This may be attributable to the diversity of the population in terms of its expectations towards

We sought to establish the extent of repeat participation in a large annual cross-sectional survey of people who inject drugs and assess its implications for analysis. We used "porn star names" (the name of each participant's first pet followed by the name of the first street in which they lived) to identify repeat participation in three Australian Illicit Drug Reporting System surveys. Over 2013-2015, 2468 porn star names (96.2%) appeared only once, 88 (3.4%) twice, and nine (0.4%) in all 3 years. We measured design effects, based on the between-cluster variability for selected estimates, of 1.01-1.07 for seven key variables. These values indicate that the complex sample is (e.g.) 7% less efficient in estimating prevalence of heroin use (ever) than a simple random sample, and 1% less efficient in estimating number of heroin overdoses (ever). Porn star names are a useful means of tracking research participants longitudinally while maintaining their anonymity. Repeat participation in the Australian Illicit Drug Reporting System is low (less than 5% per annum), meaning point-prevalence and effect estimation without correction for the lack of independence in observations is unlikely to seriously affect population inference.

To identify public perceptions of the risk to health after the poisoning of Alexander Litvinenko with polonium-210 (210Po) in London and to assess the impact of public health communications. Cross sectional telephone survey and qualitative interviews. London, United Kingdom. 1000 people completed the cross sectional survey and 86 potentially exposed people completed the qualitative interviews. Perception of risk to personal health after the 210Po incident. Qualitative interviews were analysed with an emphasis on information needs. 11.7% of the survey sample (n=117) perceived their health to be at risk. Aside from personal variables the main predictors of perceived risk to health were believing that the incident was related to terrorism (odds ratio 2.7, 95% confidence interval 1.5 to 4.6) rather than to espionage, that it was targeted at the wider public rather than one person (5.9, 3.2 to 10.9), and that it could affect people who had not been in the contaminated area (3.2, 2.1 to 5.1). Participants in the qualitative interviews were generally satisfied with the information they had received, although they would have preferred more information about their individual risk of exposure, the results of their urine tests, and the health implications of the incident. Perceptions of the public that the 210Po incident in London in 2006 was related to espionage helped to reassure them that the risks to personal health were low. In the event of future incidents it is important to ensure that detailed, comprehensible information about the risks of any exposure is available.

To assess the effects of costs on access to medicines in 11 developed countries offering different levels of prescription drug coverage for their populations. Cross-sectional study of data from the Commonwealth Fund 2014 International Health Policy Survey of Older Adults. Telephone survey conducted in 11 high-income countries: Australia, Canada, France, Germany, the Netherlands, New Zealand, Norway, Sweden, Switzerland, the UK and the USA. 22 532 adults aged 55 and older and living in the community in studied countries. Self-reported cost-related non-adherence (CRNA) in the form of either not filling a prescription or skipping doses within the last 12 months because of out-of-pocket costs. Estimated prevalence of CRNA among all older adults varied from <3% in the France, Norway, Sweden, Switzerland and the UK to 16.8% in the USA. Canada had the second highest national prevalence of CRNA (8.3%), followed by Australia (6.8%). Older adults in the USA were approximately six times more likely to report CRNA than older adults in the UK (adjusted OR=6.09; 95% CI 3.60 to 10.20). Older adults in Australia and Canada were also statistically significantly more likely to report CRNA than older adults in the UK. Across most countries, the prevalence of CRNA was higher among lower income residents and lower among residents over age 65. Observed differences in national prevalence of CRNA appear to follow lines of availability of prescription drug coverage and the extent of direct patient charges for prescriptions under available drug plans.

Among health care providers, prescription of HIV pre-exposure prophylaxis (PrEP) has been low. Little is known specifically about primary care physicians (PCPs) with regard to PrEP awareness and adoption (i.e., prescription or referral), and factors associated with adoption. To assess PrEP awareness, PrEP adoption, and factors associated with adoption among PCPs. Cross-sectional online survey conducted in April and May 2015. Members of a national professional organization for academic primary care physicians (n = 266). PrEP awareness, PrEP adoption (ever prescribed or referred a patient for PrEP [yes/no]), provider and practice characteristics, and self-rated knowledge, attitudes, and beliefs associated with adoption. The survey response rate was 8.6 % (266/2093). Ninety-three percent of respondents reported prior awareness of PrEP. Of these, 34.9 % reported PrEP adoption. In multivariable analysis of provider and practice characteristics, compared with non-adopters, adopters were more likely to provide care to more than 50 HIV-positive patients (vs. 0, aOR = 6.82, 95 % CI 2.06-22.52). Compared with non-adopters, adopters were also more likely to report excellent, very good, or good self-rated PrEP knowledge (15.1 %, 33.7 %, 30.2 % vs. 2.5 %, 18.1 %, 23.8 %, respectively; p < 0.001) and to perceive PrEP as extremely safe (35.1 % vs. 10.7 %; p = 0.002). Compared with non-adopters, adopters were less likely to perceive PrEP as being moderately likely to increase risk behaviors ("risk compensation") (12.8 % vs. 28.8 %, p = 0.02). While most respondents were aware of PrEP, only one-third of PrEP-aware PCPs reported adoption. Adopters were more likely to have experience providing HIV care and to perceive PrEP as extremely safe, and were less likely to perceive PrEP use as leading to risk compensation. To enhance PCP adoption of PrEP, educational efforts targeting PCPs without HIV care experience should be considered, as well as training

Previous studies suggest that obesity is associated with higher prostate cancer progression and mortality despite an association with lower prostate cancer incidence. This study aims to better understand these apparently inconsistent relationships among obese men by combining evidence from 3 nationally representative cross-sectional surveys. We evaluated relationships between obesity and 1) testosterone concentrations in the Third National Health and Nutrition Examination Survey (NHANES III; n=845); 2) prostate-specific antigen (PSA) in NHANES 2001-2004 (n=2458); and 3) prostate biopsy rates in the National Health Interview Survey (NHIS 2000; n=4789) population. Mean testosterone, PSA concentrations, and biopsy rates were computed for Body Mass Index (BMI) categories. Testosterone concentrations were inversely associated with obesity (P-trend <.0001) in NHANES III. In NHANES 2001-2004, obese (BMI >35) versus lean (BMI <25) men were less likely to have PSA concentrations that reached the biopsy threshold of >4 ng/mL (3% vs 8%; P <.0001). Among NHIS participants, all BMI groups had similar rates of PSA testing (P=.24). However, among men who had PSA tests, 11% of men with BMI >30 versus 16% with BMI <25, achieved a PSA threshold of 4 ng/mL; P=.01. Furthermore, biopsy rates were lower among men with BMI >30 versus BMI <25 in NHIS participants (4.6% vs 5.8%; P=.05). Obesity was associated with lower PSA-driven biopsy rates. These data support further studies to test the hypothesis that obesity affects prostate cancer detection independent of prostate cancer risk by decreasing the PSA-driven biopsy rates.

This study assessed drinking water quality, sanitation, and hygiene (WASH) conditions among 708 schoolchildren and 562 households in Dolakha and Ramechhap districts of Nepal. Cross-sectional surveys were carried out in March and June 2015. A Delagua water quality testing kit was employed on 634 water samples obtained from 16 purposively selected schools, 40 community water sources, and 562 households to examine water quality. A flame atomic absorption spectrophotometer was used to test lead and arsenic content of the same samples. Additionally, a questionnaire survey was conducted to obtain WASH predictors. A total of 75% of school drinking water source samples and 76.9% point-of-use samples (water bottles) at schools, 39.5% water source samples in the community, and 27.4% point-of-use samples at household levels were contaminated with thermo-tolerant coliforms. The values of water samples for pH (6.8-7.6), free and total residual chlorine (0.1-0.5 mg/L), mean lead concentration (0.01 mg/L), and mean arsenic concentration (0.05 mg/L) were within national drinking water quality standards. The presence of domestic animals roaming inside schoolchildren's homes was significantly associated with drinking water contamination (adjusted odds ratio: 1.64; 95% confidence interval: 1.08-2.50; p = 0.02). Our findings call for an improvement of WASH conditions at the unit of school, households, and communities.

to examine childbirth fear and identify its predictors among pregnant Chinese women. a cross-sectional descriptive questionnaire survey was conducted in a regional teaching hospital in Guangzhou, China, between October and November 2013. 353 pregnant Chinese women who were at least 18 years old, with a singleton fetus, in the third trimester of pregnancy, not at high risk for complications of pregnancy, and not having had a previous caesarean section. a social-demographic data sheet; the Chinese version of the Childbirth Attitude Questionnaire and the Spielberger׳s State-Trait Anxiety Inventory; and the short form of 32-item Chinese Childbirth Self-Efficacy Inventory. the pregnant Chinese women reported moderate levels of childbirth fear. The pregnant Chinese women who were younger, with lower educational level, not satisfied with their husbands׳ support, and with previous experience of miscarriage reported higher level of childbirth fear. Pregnant women׳s childbirth self-efficacy, state anxiety and trait anxiety were correlated with childbirth fear. The best-fit regression analysis revealed four variables that explained 28% of variance in childbirth fear: trait anxiety, state anxiety, age and previous experience of miscarriage. this study highlighted the connection between childbirth fear, state and trait anxiety, childbirth self-efficacy, age, education and previous miscarriage among pregnant Chinese women. the CAQ was an appropriate method to measure childbirth fear in pregnant Chinese women. The health-care professionals should be sensitive toward issues that could affect levels of childbirth fear in pregnant Chinese women, including age, education and previous miscarriage.

Registered nurses are under-represented in the primary health care setting both internationally and in Australia, and this shortage is predicted to worsen. To address the increasingly complex healthcare needs of an ageing population, it is vital to develop and sustain a primary health care nursing workforce, yet attracting nurses is challenging. In Australia, registered nurses graduating from university typically commence their careers in hospital-based transition to professional practice programs. Similar programs in primary health care settings may be a valuable strategy for developing the primary health care nursing workforce, yet little is known about nursing students desire to work in this setting, factors that influence this, or their expectations of primary health care-focused transition to professional practice programs. This study sought to identify factors associated with final year nursing students' desire to work in primary health care setting including demographic factors, expectations of future employment conditions, and job content. It also explored expectations of graduate transition programs based in primary health care. A cross-sectional survey design comprising a quantitative online survey. 14 Australian universities from all states/territories, both rural and urban. 530 final-year nursing students. Binary logistic regression identifying factors contributing to desire to work in primary health care. The desire of nursing students to work in primary health care is associated with older age, greater perceived value of employment conditions including flexibility, and less perceived importance of workplace support. Collaborative efforts from primary health care nurses, health professionals, academics and policy makers are needed to attract new graduate nurses to primary health care. Crown Copyright © 2017.

2017-01-06

Young people's perspectives on the association between having a family member with a chronic health concern (FHC) and their own health are under-researched. This study used young people's reports to assess the prevalence of FHCs and their association with negative health outcomes, with an aim of identifying potential inequalities between marginalised and non-marginalised young people. Family cohesion was examined as a moderating factor. Cross-sectional data from the Australian Child Wellbeing Project survey were used. Respondents were asked whether someone in their family experienced one or more FHCs (disability, mental illness or drug/alcohol addiction). In addition, their experience of different psychosomatic symptoms (headache, sleeplessness, irritability, etc), aspects of family relationships and social and economic characteristics (disability, materially disadvantaged and Indigenous) were documented. Nationally representative Australian sample. 1531 students in school years 4 and 6 and 3846 students in year 8. A quarter of students reported having an FHC (years 4 and 6: 23.96% (95% CI 19.30% to 28.62%); year 8: 25.35% (95% CI 22.77% to 27.94%)). Significantly, more students with FHCs than those without reported experiencing 2 or more negative health symptoms at least weekly (OR=1.78; 95% CI 1.19 to 2.65; p<0.01). However, an independent relationship between FHCs and symptom load was only found in the case of FHC-drug/alcohol addiction. Marginalised students and students reporting low family cohesion had an increased prevalence of FHCs and notably higher symptom loads where FHCs were present. Level of family cohesion did not impact the relationship between FHCs and symptom load. The burden of FHCs is inequitably distributed between marginalised and non-marginalised groups, and between young people experiencing different levels of family cohesion. More work is required regarding appropriate targets for community and family-level interventions to support young

This study evaluates total water intake (TWI) from plain water, beverages and foods among Lebanese children and compares TWI to dietary reference intakes (DRIs). In a national cross-sectional survey, data on demographic, socioeconomic, anthropometric, and physical activity characteristics were obtained from 4 to 13-year-old children (n = 752). Food and beverage consumption patterns were assessed using a validated food-frequency questionnaire. TWI was estimated at 1651 mL/day, with beverages contributing 72% of the TWI compared to 28% from foods. Beverages with the highest contribution to TWI included plain water, fruit juice and soda. A significantly higher proportion of 9-13-year-old children failed to meet the DRIs compared to 4-8 years old (92%-98% vs. 74%). Gender differentials were observed with a significantly higher proportion of boys meeting the DRIs compared to girls. The water to energy ratio ranged between 0.84 and 0.87, which fell short of meeting the desirable recommendations. In addition, children from higher socioeconomic status had higher intakes of water from milk and bottled water, coupled with lower water intakes from sodas. The study findings show an alarming high proportion of Lebanese children failing to meet TWI recommendations, and call for culture-specific interventions to instill healthy fluid consumption patterns early in life.

In the UK, NHS hospitals receive large amounts of evidence-based recommendations for care delivery from the National Institute for Health and Care Excellence (NICE) and other organisations. Little is known about how NHS organisations implement such guidance and best practice for doing so. This study was therefore designed to examine the dissemination, decision-making, and monitoring processes for NICE interventional procedures (IP) guidance and to investigate the barriers and enablers to the implementation of such guidance. A cross-sectional survey questionnaire was developed and distributed to individuals responsible for managing the processes around NICE guidance in all 181 acute NHS hospitals in England, Scotland, Wales and Northern Ireland. A review of acute NHS hospital policies for implementing NICE guidance was also undertaken using information available in the public domain and from organisations' websites. The response rate to the survey was 75 % with 135 completed surveys received. Additionally, policies from 25 % of acute NHS hospitals were identified and analysed. NHS acute hospitals typically had detailed processes in place to implement NICE guidance, although organisations recognised barriers to implementation including organisational process barriers, clinical engagement and poor targeting with a large number of guidance issued. Examples of enablers to, and good practice for, implementation of guidance were found, most notably the value of shared learning experiences between NHS hospitals. Implications for NICE were also identified. These included making improvements to the layout of guidance, signposting on the website and making better use of their shared learning platform. Most organisations have robust processes in place to deal with implementing guidance. However, resource limitations and the scope of guidance received by organisations create barriers relating to organisational processes, clinician engagement and financing of new procedures

In many European countries, foreign nationals experience, on average, less favorable treatment outcomes in rehabilitative care than the respective majority population. In Germany, this for example is reflected in a lower occupational performance and a higher risk of disability retirement after rehabilitation as analyses of routine data show. However, little is known about the perspective of health care users. The aim of the present study was to compare self-rated treatment outcomes between German and non-German nationals undergoing in-patient medical rehabilitation in Germany. We analyzed data from a cross-sectional representative rehabilitation patient survey of 239,811 patients from 642 clinics in Germany who completed about 3 weeks of in-patient rehabilitative treatment. The self-rating of the treatment outcome was based on a dichotomized Likert scale consisting of three items. A multilevel logistic regression analysis adjusted for various demographic, socio-economic, health and other covariates was conducted to examine differences in the self-rated treatment outcome between German and non-German nationals. Of the 239,811 respondents 0.9% were nationals from Turkey, 0.8% had a nationality from a former Yugoslavian country, 0.9% held a nationality from the South European countries Portugal, Spain, Italy or Greece and 1.9% were nationals from other countries. Non-German nationals reported a less favorable self-rated outcome than Germans. Adjusted odds ratios [OR] for reporting a less favorable treatment outcome were 1.24 (95%-confidence interval [95%-CI]: 1.12-1.37) for nationals from the South European countries Portugal/Spain/Italy/Greece, 1.62 (95%-CI: 1.45-1.80) for Turkish nationals and 1.68 (95%-CI: 1.52-1.85) for nationals from Former Yugoslavia. Knowledge on health outcomes from the patients' point of view is important for the provision of patient-centered health care. Our study showed that non-German nationals report less favorable outcomes of

Flow in curved ducts of varying cross-section

Two numerical methods for solving the incompressible Navier-Stokes equations are compared with each other by applying them to calculate laminar and turbulent flows through curved ducts of regular cross-section. Detailed comparisons, between the computed solutions and experimental data, are carried out in order to validate the two methods and to identify their relative merits and disadvantages. Based on the conclusions of this comparative study a numerical method is developed for simulating viscous flows through curved ducts of varying cross-sections. The proposed method is capable of simulating the near-wall turbulence using fine computational meshes across the sublayer in conjunction with a two-layer k-epsilon model. Numerical solutions are obtained for: (1) a straight transition duct geometry, and (2) a hydroturbine draft-tube configuration at model scale Reynolds number for various inlet swirl intensities. The report also provides a detailed literature survey that summarizes all the experimental and computational work in the area of duct flows.

Caseload midwifery has many benefits for women and their babies, however only around 8% of women receive caseload care in the public maternity system in Australia. Midwives working within caseload models are required to provide activity-based care (working on-call, responsively to the needs of their caseload of women) rather than undertaking shift work. There has been debate regarding the impact of caseload work on midwives, but recently caseload work has been associated with higher professional satisfaction and lower burnout when compared to midwives working in traditional models. However, there continues to be debate about the impact of caseload on midwives, so further investigation is needed. A national cross-sectional survey of midwives working in Australian public hospitals that have birthing services was undertaken. We explored burnout and midwives' attitudes to their professional role using the Copenhagen Burnout Inventory and the Midwifery Process Questionnaire, respectively. Comparisons were made across three groups of midwives: those who worked in the caseload model, midwives who did not work in this model but worked in a hospital with a caseload model, and midwives who worked in a hospital without a caseload model. We received 542 responses from midwives from 111 hospitals from all Australian states and one of the territories. Of respondents, 107 midwives worked in a caseload model, 212 worked in a hospital with a caseload model but did not work in caseload, and 220 midwives worked in a hospital without a caseload model. Midwives working in caseload had significantly lower burnout scores in the personal and work-related burnout subscales, and a trend toward lower scores in the client-related burnout subscale. They also had higher scores across all four subscales of the midwifery process questionnaire, demonstrating more positive attitudes to their professional role. Although concerns have been raised regarding the impact of caseload midwifery on midwives

A vaccine to prevent human papilloma virus (HPV) infection has been licensed recently in the United States of America and Australia. The aim of this study was to assess community attitudes to the introduction of HPV vaccine in the State of South Australia. A cross-sectional survey was conducted by computer-aided telephone interviews in February 2006. The survey assessed adult and parental attitudes to the introduction of HPV vaccine to provide protection against a sexually transmitted disease caused by HPV and against cervical cancer. Two thousand interviews were conducted in metropolitan and rural households. Two per cent of respondents knew that persistent HPV infection caused cervical cancer and a further 7% were aware that the cause was viral. The majority of adults interviewed (83%) considered that both men and women should receive HPV vaccine and 77% of parents agreed that they would have their child/children immunised. Parents were mainly concerned about possible side effects of the vaccine (66%), with only 0.2% being concerned about discussing a sexually transmitted disease with their children and 5% being concerned that use of the vaccine may lead to promiscuity. Our findings suggest that public health education campaigns for HPV vaccination will find a majority of parents receptive to their children being vaccinated, but attention must be paid to appropriate explanation about HPV infection as the cause of cervical cancer and education about the safety of the HPV vaccine.

To estimate obesity prevalence among healthcare professionals in England and compare prevalence with those working outside of the health services. Cross-sectional study based on data from 5 years (2008-2012) of the nationally representative Health Survey for England. England. 20 103 adults aged 17-65 years indicating they were economically active at the time of survey classified into four occupational groups: nurses (n=422), other healthcare professionals (n=412), unregistered care workers (n=736) and individuals employed in non-health-related occupations (n=18 533). Prevalence of obesity defined as body mass index ≥30.0 with 95% CIs and weighted to reflect the population. Obesity prevalence was high across all occupational groups including: among nurses (25.1%, 95% CI 20.9% to 29.4%); other healthcare professionals (14.4%, 95% CI 11.0% to 17.8%); non-health-related occupations (23.5%, 95% CI 22.9% to 24.1%); and unregistered care workers who had the highest prevalence of obesity (31.9%, 95% CI 28.4% to 35.3%). A logistic regression model adjusted for sociodemographic composition and survey year indicated that, compared with nurses, the odds of being obese were significantly lower for other healthcare professionals (adjusted OR (aOR) 0.52, 95% CI 0.37 to 0.75) and higher for unregistered care workers (aOR 1.46, 95% CI 1.11 to 1.93). There was no significant difference in obesity prevalence between nurses and people working in non-health-related occupations (aOR 0.94, 95% CI 0.74 to 1.18). High obesity prevalence among nurses and unregistered care workers is concerning as it increases the risks of musculoskeletal conditions and mental health conditions that are the main causes of sickness absence in health services. Further research is required to better understand the reasons for high obesity prevalence among healthcare professionals in England to inform interventions to support individuals to achieve and maintain a healthy weight. © Article

Several studies from other countries have shown that bullying, harassment, abuse or belittlement are a regular phenomenon faced not only by medical students, but also junior doctors, doctors undertaking research and other healthcare professionals. While research has been carried out on bullying experienced by psychiatrists and psychiatry trainees in Pakistan no such research has been conducted on medical students in this country. We conducted a cross-sectional questionnaire survey on final year medical students in six medical colleges of Pakistan. The response rate was 63%. Fifty-two percent of respondents reported that they had faced bullying or harassment during their medical education, about 28% of them experiencing it once a month or even more frequently. The overwhelming form of bullying had been verbal abuse (57%), while consultants were the most frequent (46%) perpetrators. Students who were slightly older, males, those who reported that their medical college did not have a policy on bullying or harassment, and those who felt that adequate support was not in place at their medical college for bullied individuals, were significantly more likely to have experienced bullying. Bullying or harassment is faced by quite a large proportion of medical students in Pakistan. The most frequent perpetrators of this bullying are consultants. Adoption of a policy against bullying and harassment by medical colleges, and providing avenues of support for students who have been bullied may help reduce this phenomenon, as the presence of these two was associated with decreased likelihood of students reporting having being bullied.

Management of hypertension and diabetes in cancer survivors is an important issue; however, not much is known about the level of management of such chronic disease in Korea. This study therefore assessed the prevalence, awareness, control, and treatment of hypertension and diabetes in Korean cancer survivors compared to non-cancer survivors. A cross-sectional design was employed, wherein data were obtained from standardized questionnaires completed by 943 cancer survivors and 41,233 non-cancer survivors who participated in the Fourth and Fifth Korea National Health and Nutrition Examination Surveys (2007-2011). We calculated adjusted proportions for prevalence and management of hypertension and diabetes in non-cancer survivors and cancer survivors. We also assessed the associated factors with prevalence and management of cancer survivors. Cancer survivors are more likely than the general population to have higher prevalence, awareness, treatment, and control of hypertension. However, diabetic management was not significantly higher in cancer survivors than in non-cancer survivors, despite their having a higher prevalence. Several factors, such as, age, drinking, years since cancer diagnosis, self-perceived health status, and specific cancer types were found to affect to management of hypertension and diabetes. These data suggest that cancer survivors appear to be better than non-cancer survivors at management of hypertension, but not diabetes. There is a need for healthcare providers to recognize the importance of long-term chronic disease management for cancer survivors and for the care model to be shared between primary care physicians and oncologists.

Assessment of the neutron cross section database for mercury for the ORNL spallation source

1996-06-01

Neutron source generation based on a high energy particle accelerator has been considered as an alternative to the canceled Advanced Neutron Source project at Oak Ridge National Laboratory. The proposed technique consists of a spallation neutron source in which neutrons are produced via the interaction of high-energy charged particles in a heavy metal target. Preliminary studies indicate that liquid mercury bombarded with GeV protons provides an excellent neutron source. Accordingly, a survey has been made of the available neutron cross-section data. Since it is expected that spectral modifiers, specifically moderators, will also be incorporated into the source design, the surveymore » included thermal energy, resonance region, and high energy data. It was found that data of individual isotopes were almost non-existent and that the only evaluation found for the natural element had regions of missing data or discrepant data. Therefore, it appears that to achieve the desired degree of accuracy in the spallation source design it is necessary to re-evaluate the mercury database including making new measurements. During the presentation the currently available data will be presented and experiments proposed which can lead to design quality cross sections.« less

The use of social media by health care organizations is growing and provides Web-based tools to connect patients, caregivers, and providers. The aim was to determine the use and factors predicting the use of social media for health care-related purposes among medically underserved primary care patients. A cross-sectional survey was administered to 444 patients of a federally qualified community health center. Community health center patients preferred that their providers use email, cell phones for texting, and Facebook and cell phone apps for sharing health information. Significantly more Hispanic than white patients believed their providers should use Facebook (P=.001), YouTube (P=.01), and Twitter (P=.04) for sharing health information. Use and intentions to use social media for health-related purposes were significantly higher for those patients with higher subjective norm scores. Understanding use and factors predicting use can increase adoption and utilization of social media for health care-related purposes among underserved patients in community health centers.

To evaluate the associations between population-wide loss and gain in weight with diabetes prevalence, incidence, and mortality, as well as cardiovascular and cancer mortality trends, in Cuba over a 30 year interval. Repeated cross sectional surveys and ecological comparison of secular trends. Cuba and the province of Cienfuegos, from 1980 to 2010. Measurements in Cienfuegos included a representative sample of 1657, 1351, 1667, and 1492 adults in 1991, 1995, 2001, and 2010, respectively. National surveys included a representative sample of 14 304, 22 851, and 8031 participants in 1995, 2001, and 2010, respectively. Changes in smoking, daily energy intake, physical activity, and body weight were tracked from 1980 to 2010 using national and regional surveys. Data for diabetes prevalence and incidence were obtained from national population based registries. Mortality trends were modelled using national vital statistics. Rapid declines in diabetes and heart disease accompanied an average population-wide loss of 5.5 kg in weight, driven by an economic crisis in the mid-1990s. A rebound in population weight followed in 1995 (33.5% prevalence of overweight and obesity) and exceeded pre-crisis levels by 2010 (52.9% prevalence). The population-wide increase in weight was immediately followed by a 116% increase in diabetes prevalence and 140% increase in diabetes incidence. Six years into the weight rebound phase, diabetes mortality increased by 49% (from 9.3 deaths per 10 000 people in 2002 to 13.9 deaths per 10 000 people in 2010). A deceleration in the rate of decline in mortality from coronary heart disease was also observed. In relation to the Cuban experience in 1980-2010, there is an association at the population level between weight reduction and death from diabetes and cardiovascular disease; the opposite effect on the diabetes and cardiovascular burden was seen on population-wide weight gain.

The Chinese health care system must meet the needs of 19% of the world's population. Despite recent economic growth, health care resources are unevenly distributed. This creates the potential for job stress and burnout. We therefore conducted a survey among anesthesiologists in the Beijing-Tianjin-Hebei region focusing on job satisfaction and burnout to determine the incidence and associated factors. A large cross-sectional study was performed in the Beijing-Tianjin-Hebei region of China. The anonymous questionnaire was designed to collect and analyze the following information: (1) demographic characteristics and employer information; (2) job satisfaction assessed by Minnesota Satisfaction Questionnaire; (3) burnout assessed by Maslach Burnout Inventory-Human Service Survey; and (4) sleep pattern and physician-patient communication. Surveys were completed and returned from 211 hospitals (response rate 74%) and 2873 anesthesiologists (response rate 70%) during the period of June to August 2015. The overall job satisfaction score of Minnesota Satisfaction Questionnaire was 65.3 ± 11.5. Among the participants, 69% (95% confidence interval [CI], 67%-71%) met the criteria for burnout. The prevalence of high emotional exhaustion, high depersonalization, and low personal accomplishment was 57% (95% CI, 55%-59%), 49% (95% CI, 47%-51%), and 57% (95% CI, 55%-58%), respectively. Using multivariable logistic regression analysis, we found that age, hospital category, working hours per week, caseload per day, frequency of perceived challenging cases, income, and sleep quality were independent variables associated with burnout. Anesthesiologists with a high level of depersonalization tended to engage in shorter preoperative conversations with patients, provide less information about pain or the procedure, and to have less empathy with them. The anesthesiologists in the Beijing-Tianjin-Hebei region of China expressed a below-average level of job satisfaction, and suffered a

France is currently facing a vaccine-hesitancy crisis. We conducted a questionnaire-based telephone interview with a large sample of general practitioners (GPs) as they play a crucial role in the vaccination process. Our main objectives were to study the GPs' vaccination behaviors when it comes to their own vaccination and that of their relatives, and the vaccine recommendations made to their patients. We also aimed to understand their opinion related to the severity of vaccine-preventable diseases and to assess their trust in various sources of information. Finally, we enquired about their opinion in terms of vaccination-related tools that could help them in their daily practice. The article aimed to present the design of this panel and survey. Four samples of GPs (one national and three regional) were selected among all the French GPs (metropolitan France) using random sampling. Five cross-sectional surveys should be conducted with that panel. The mean targeted sample size is 2350 GPs for each survey. The survey dedicated to vaccination was conducted by telephone or on the Internet. GPs were included in the survey between December 2013 and February 2014. The national sample included 1582 GPs (response rate: 46%) and the three regional samples included 1297 GPs (response rate: 44%). The survey dedicated to vaccination was conducted between April and July 2014; the national sample response rate was 92% (1582/1712). The results of the first wave of surveys, conducted on a large sample of French GPs, provide important information to guide the French vaccination policy. Copyright © 2015 Elsevier Masson SAS.

ABSTRACT Background: Improving maternal health is a global challenge. In Ghana, maternal morbidity and mortality rates remain high, particularly in rural areas. Antenatal care (ANC) attendance is known to improve maternal health. However, few studies have updated current knowledge regarding determinants of ANC attendance. Objective: This study examined factors associated with ANC attendance in predominantly rural Ghana. Methods: We conducted a cross-sectional study at three sites (i.e. Navrongo, Kintampo, and Dodowa) in Ghana between August and September 2013. We selected 1500 women who had delivered within the two years preceding the survey (500 from each site) using two-stage random sampling. Data concerning 1497 women’s sociodemographic characteristics and antenatal care attendance were collected and analyzed, and factors associated with attending ANC at least four times were identified using logistic regression analysis. Results: Of the 1497 participants, 86% reported attending ANC at least four times, which was positively associated with possession of national health insurance (AOR 1.64, 95% CI: 1.14–2.38) and having a partner with a high educational level (AOR 1.64, 95% CI: 1.02–2.64) and negatively associated with being single (AOR 0.39, 95% CI: 0.22–0.69) and cohabiting (AOR 0.57, 95% CI: 0.34–0.97). In site-specific analyses, factors associated with ANC attendance included marital status in Navrongo; marital status, possession of national health insurance, partners’ educational level, and wealth in Kintampo; and preferred pregnancy timing in Dodowa. In the youngest, least educated, and poorest women and women whose partners were uneducated, those with health insurance were more likely to report at least four ANC attendances relative to those who did not have insurance. Conclusions: Ghanaian women with low socioeconomic status were less likely to report at least four ANC attendances during pregnancy if they did not possess health insurance. The

Eating location has been linked with variations in diet quality including the consumption of low-nutrient energy-dense food, which is a recognised risk factor for obesity. Cross-sectional data from 4736 adults aged 19 years and over from Years 1-6 of the UK National Diet and Nutrition Survey (NDNS) Rolling Programme (RP) (2008-2014) were used to explore food consumption patterns by eating location. Eating location was categorized as home, work, leisure places, food outlets and "on the go". Foods were classified into two groups: core (included in the principal food groups and considered important/acceptable within a healthy diet) and non-core (all other foods). Out of 97,748 eating occasions reported, the most common was home (67-90% of eating occasions). Leisure places, food outlets and "on the go" combined contributed more energy from non-core (30%) than from core food (18%). Analyses of modulating factors revealed that sex, income, frequency of eating out and frequency of drinking were significant factors affecting consumption patterns ( p < 0.01). Our study provides evidence that eating patterns, behaviours and resulting diet quality vary by location. Public health interventions should focus on availability and access to healthy foods, promotion of healthy food choices and behaviours across multiple locations, environments and contexts for food consumption.

Sexual intercourse among Malaysian adolescents is a major concern, especially with the worry of HIV/AIDS. This study was done to determine the prevalence of sexual intercourse among secondary school students aged 12 to 19 years in Negeri Sembilan, Malaysia. This is a cross-sectional school survey conducted on 4,500 adolescent students based on a structured questionnaire. Data were collected using the self-administered questionnaire (translated version of the Youth Risk Behaviour Surveillance in Bahasa Malaysia). The study showed that 5.4 percent of the total sample were reported to have had sexual intercourse. The proportion among male students who had had sex was higher (8.3 percent) compared with female students (2.9 percent). The mean age at first sexual intercourse was 15 years. One percent of students reported that they had been pregnant or had made someone else pregnant. Adolescent sexual intercourse was significantly associated with (1) socio-demographical factors (age, gender); (2) environmental factors (staying with parents); and (3) substance use (alcohol use, cigarette smoking, drug use), even after adjustment for demographical factors. The survey showed that 20.8 percent of respondents had taken alcohol, 14.0 percent had smoked cigarettes, 2.5 percent had tried marijuana, 1.2 percent had tried ecstasy pills, 2.6 percent had tried glue sniffing, 0.7 percent had tried heroin, and 0.7 percent had intravenous drugs. Prevalence of sexual intercourse among Malaysian adolescents was relatively low compared to developed countries. However, certain groups of adolescents tend to be at higher risk of engaging in sexual intercourse. This problem should be addressed early by targeting these groups of high-risk adolescents.

For the past more than 50 years, the World Health Organisation has acknowledged through empirical findings that health workers that learn together work together effectively to provide the best care for their patients. This study aimed to: (1) describe the perceived extent of interprofessional education (IPE) experience among Filipino occupational therapists (OTs), physical therapists (PTs), and speech-language-pathologists (SLPs); (2) identify their attitudes towards interprofessional collaboration (IPC); and (3) compare their attitudes towards IPC according to: prior IPE experience, classification of IPE experience, profession, years of practice, and practice setting. Using a cross-sectional survey design, a two-part questionnaire was sent to Filipino OTs, PTs, and SLPs working in the Philippines via an online survey application. The first part of the survey contained eight items of demographic information and the second part contained the 14-item Attitudes Towards Health Care Teams Scale (ATHCTS). Findings revealed that among the Filipino OT, PT and SLP respondents (n = 189), 70.9% had prior experience on IPE. Moreover, the three most commonly used IPE teaching-learning strategies were case discussion (clinical setting), small group discussion, didactics, and case discussion (community setting), while the use of didactics and case discussion (community setting) yielded more agreeable attitudes towards IPC. Among the 14 items in the ATHCTS, 11 were rated with agreeability and three items with neutrality. For professional variables, only the practice setting variable yielded a statistically significant finding confirming those working in the academia to be more agreeable towards IPC compared to other settings. However, years of practice and professional background variables both yielded no statistically significant difference implying no association between years of practice and attitude towards IPC and a homogenous composition among respondents, respectively

Ongoing armed conflict in Syria has caused large scale displacement. Approximately half of the population of Syria have been displaced including the millions living as refugees in neighboring countries. We sought to assess the health and nutrition of Syrian refugees affected by the conflict. Representative cross-sectional surveys of Syrian refugees were conducted between October 2 and November 30, 2013 in Lebanon, April 12 and May 1, 2014 in Jordan, and May 20 and 31, 2013 in Iraq. Surveys in Lebanon were organized in four geographical regions (North, South, Beirut/Mount Lebanon and Bekaa). In Jordan, independent surveys assessed refugees residing in Za'atri refugee camp and refugees residing among host community nationwide. In Iraq, refugees residing in Domiz refugee camp in the Kurdistan region were assessed. Data collected on children aged 6 to 59 months included anthropometric indicators, morbidity and feeding practices. In Jordan and Lebanon, data collection also included hemoglobin concentration for children and non-pregnant women aged 15 to 49 years, anthropometric indicators for both pregnant and non-pregnant women, and household level indicators such as access to safe water and sanitation. The prevalence of global acute malnutrition among children 6 to 59 months of age was less than 5 % in all samples (range 0.3-4.4 %). Prevalence of acute malnutrition among women 15 to 49 years of age, defined as mid-upper arm circumference less than 23.0 cm, was also relatively low in all surveys (range 3.5-6.5 %). For both children and non-pregnant women, anemia prevalence was highest in Za'atri camp in Jordan (48.4 % and 44.8 %, respectively). Most anemia was mild or moderate; prevalence of severe anemia was less than or equal to 1.1 % in all samples of children and women. Despite the ongoing conflict, results from all surveys indicate that global acute malnutrition is relatively low in the assessed Syrian refugee populations. However, prevalence of anemia

Background Although systematic reviews of health care interventions are an invaluable tool for health care providers and researchers, many potential authors never publish reviews. This study attempts to determine why some people with interest in performing systematic reviews do not subsequently publish a review; and what steps could possibly increase review completion. Methods Cross-sectional survey by email and facsimile of the 179 participants in Australasian Cochrane Centre training events between 1998 and 2000. Results Ninety-two participants responded to the survey (51 percent). Response rate of deliverable surveys was 82 percent (92/112). The remainder of the participants had invalid or no contact information on file. More than 75 percent of respondents felt that the current workshops met their needs for training. The most critical barriers to completion of a Cochrane review were: lack of time (80 percent), lack of financial support (36 percent), methodological problems (23 percent) and problems with group dynamics (10 percent). Conclusions Strategies to protect reviewer time and increase the efficiency of the review process may increase the numbers of trained reviewers completing a systematic review. PMID:12057022

To test the cross-cultural validity of the U.S. Patient Perception of Integrated Care (PPIC) Survey in a Dutch sample using a standardized procedure. Primary data collected from patients of five primary care centers in the south of the Netherlands, through survey research from 2014 to 2015. Cross-sectional data collected from patients who saw multiple health care providers during 6 months preceding data collection. The PPIC survey includes 59 questions that measure patient perceived care integration across providers, settings, and time. Data analysis followed a standardized procedure guiding data preparation, psychometric analysis, and included invariance testing with the U.S. dataset. Latent scale structures of the Dutch and U.S. survey were highly comparable. Factor "Integration with specialist" had lower reliability scores and noninvariance. For the remaining factors, internal consistency and invariance estimates were strong. The standardized cross-cultural validation procedure produced strong support for comparable psychometric characteristics of the Dutch and U.S. surveys. Future research should examine the usability of the proposed procedure for contexts with greater cultural differences. © Health Research and Educational Trust.

Objectives This article investigates various reasons for sickness presenteeism (SP), that is, going to work despite illness. The research questions asked is: What are the main reported reasons for SP in Norway and Sweden? Design Cross-sectional survey in Norway and Sweden. Use of binomial logistic regression analysis. Participants A random sample of people aged between 20 and 60 years was obtained from complete and updated databases of the Norwegian and Swedish populations. A postal questionnaire was sent to the selected individuals, with response rate 33% (n=2843). 2533 workers responded to questions about SP during the last 12 months. Primary and secondary outcome measures The article informs about the distribution of reasons for SP in Norway and Sweden, selected by the respondents from a closed list. The article also examines which factors influence the most often reported reasons for SP. Results 56% of the Norwegian and Swedish respondents experienced SP in the previous year. The most frequently reported reasons for SP include not burden colleagues (43%), enjoy work (37%) and feeling indispensable (35%). A lower proportion of Norwegians state that they cannot afford taking sick leave adjusted OR (aOR 0.16 (95% CI 0.10 to 0.22)), while a higher proportion of Norwegians refer to that they enjoy their work (aOR=1.64 (95% CI 1.28 to 2.09)). Women and young workers more often report that they do not want to burden their colleagues. Managers (aOR=2.19 (95% CI 1.67 to 2.86)), highly educated persons and the self-employed more often report that they are indispensable. Conclusions Positive and negative reasons for SP are reported, and there are significant differences between respondents from the two countries. The response rate is low and results must be interpreted with caution. Study design Cross-sectional study. PMID:24523425

Objectives To identify public perceptions of the risk to health after the poisoning of Alexander Litvinenko with polonium-210 (210Po) in London and to assess the impact of public health communications. Design Cross sectional telephone survey and qualitative interviews. Setting London, United Kingdom. Participants 1000 people completed the cross sectional survey and 86 potentially exposed people completed the qualitative interviews. Main outcome measures Perception of risk to personal health after the 210Po incident. Qualitative interviews were analysed with an emphasis on information needs. Results 11.7% of the survey sample (n=117) perceived their health to be at risk. Aside from personal variables the main predictors of perceived risk to health were believing that the incident was related to terrorism (odds ratio 2.7, 95% confidence interval 1.5 to 4.6) rather than to espionage, that it was targeted at the wider public rather than one person (5.9, 3.2 to 10.9), and that it could affect people who had not been in the contaminated area (3.2, 2.1 to 5.1). Participants in the qualitative interviews were generally satisfied with the information they had received, although they would have preferred more information about their individual risk of exposure, the results of their urine tests, and the health implications of the incident. Conclusions Perceptions of the public that the 210Po incident in London in 2006 was related to espionage helped to reassure them that the risks to personal health were low. In the event of future incidents it is important to ensure that detailed, comprehensible information about the risks of any exposure is available. PMID:17975252

Around 200 million adults in China have hypertension, but few are treated or achieve adequate control of their blood pressure. Available and affordable medications are important for successfully controlling hypertension, but little is known about current patterns of access to, and use of, antihypertensive medications in Chinese primary health care. We used data from a nationwide cross-sectional survey (the China Patient-Centered Evaluative Assessment of Cardiac Events Million Persons Project primary health care survey), which was undertaken between November, 2016 and May, 2017, to assess the availability, cost, and prescription patterns of 62 antihypertensive medications at primary health-care sites across 31 Chinese provinces. We surveyed 203 community health centres, 401 community health stations, 284 township health centres, and 2474 village clinics to assess variation in availability, cost, and prescription by economic region and type of site. We also assessed the use of high-value medications, defined as guideline-recommended and low-cost. We also examined the association of medication cost with availability and prescription patterns. Our study sample included 3362 primary health-care sites and around 1 million people (613 638 people at 2758 rural sites and 478 393 people at 604 urban sites). Of the 3362 sites, 8·1% (95% CI 7·2-9·1) stocked no antihypertensive medications and 33·8% (32·2-35·4) stocked all four classes that were routinely used. Village clinics and sites in the western region of China had the lowest availability. Only 32·7% (32·2-33·3) of all sites stocked high-value medications, and few high-value medications were prescribed (11·2% [10·9-11·6] of all prescription records). High-cost medications were more likely to be prescribed than low-cost alternatives. China has marked deficiencies in the availability, cost, and prescription of antihypertensive medications. High-value medications are not preferentially used. Future efforts to

Augmented cross-sectional studies with abbreviated follow-up for estimating HIV incidence.

Cross-sectional HIV incidence estimation based on a sensitive and less-sensitive test offers great advantages over the traditional cohort study. However, its use has been limited due to concerns about the false negative rate of the less-sensitive test, reflecting the phenomenon that some subjects may remain negative permanently on the less-sensitive test. Wang and Lagakos (2010, Biometrics 66, 864-874) propose an augmented cross-sectional design that provides one way to estimate the size of the infected population who remain negative permanently and subsequently incorporate this information in the cross-sectional incidence estimator. In an augmented cross-sectional study, subjects who test negative on the less-sensitive test in the cross-sectional survey are followed forward for transition into the nonrecent state, at which time they would test positive on the less-sensitive test. However, considerable uncertainty exists regarding the appropriate length of follow-up and the size of the infected population who remain nonreactive permanently to the less-sensitive test. In this article, we assess the impact of varying follow-up time on the resulting incidence estimators from an augmented cross-sectional study, evaluate the robustness of cross-sectional estimators to assumptions about the existence and the size of the subpopulation who will remain negative permanently, and propose a new estimator based on abbreviated follow-up time (AF). Compared to the original estimator from an augmented cross-sectional study, the AF estimator allows shorter follow-up time and does not require estimation of the mean window period, defined as the average time between detectability of HIV infection with the sensitive and less-sensitive tests. It is shown to perform well in a wide range of settings. We discuss when the AF estimator would be expected to perform well and offer design considerations for an augmented cross-sectional study with abbreviated follow-up. © 2011, The

Low job satisfaction is linked to higher staff turnover and intensified shortages in healthcare providers (HCP). This study investigates the level of, and factors associated with, HCP job satisfaction in the national primary healthcare (PHC) network in Lebanon. The study adopts a cross-sectional design to survey HCP at 99 PHC centres distributed across the country between October 2013 and May 2014. The study questionnaire consisted of four sections: socio-demographics/professional background, employment characteristics, level of job satisfaction (Measure of Job Satisfaction scale) and level of professional burnout (Maslach Burnout Inventory-HSS scale). A total of 1,000 providers completed the questionnaire (75.8% response rate). Bivariate and multivariate regression analyses were used to identify factors significantly associated with job satisfaction. Findings of the study highlight an overall mean job satisfaction score of 3.59 (SD 0.54) indicating that HCP are partially satisfied. Upon further examination, HCP were least satisfied with pay, training and job prospects. Gender, age, career plans, salary, exposure to violence, and level of burnout were significantly associated with the overall level of job satisfaction which was also associated with increased likelihood to quit. Overall, the study highlights how compensation, development and protection of PHC HCP can influence their job satisfaction. Recommendations include the necessity of developing a nationally representative committee, led by the Ministry of Public Health, to examine the policies and remuneration scales within the PHC sector and suggest mechanisms to bridge the pay differential with other sectors. The effective engagement of key stakeholders with the development, organisation and evaluation of professional development programmes offered to HCP in the PHC sector remains crucial. Concerned stakeholders should assess and formulate initiatives and programmes that enrich the physical, psychological

Novel Phenotype Issues Raised in Cross-National Epidemiological Research on Drug Dependence

Stage-transition models based on the American Diagnostic and Statistical Manual (DSM) generally are applied in epidemiology and genetics research on drug dependence syndromes associated with cannabis, cocaine, and other internationally regulated drugs (IRD). Difficulties with DSM stage-transition models have surfaced during cross-national research intended to provide a truly global perspective, such as the work of the World Mental Health Surveys (WMHS) Consortium. Alternative simpler dependence-related phenotypes are possible, including population-level count process models for steps early and before coalescence of clinical features into a coherent syndrome (e.g., zero-inflated Poisson regression). Selected findings are reviewed, based on ZIP modeling of alcohol, tobacco, and IRD count processes, with an illustration that may stimulate new research on genetic susceptibility traits. The annual National Surveys on Drug Use and Health can be readily modified for this purpose, along the lines of a truly anonymous research approach that can help make NSDUH-type cross-national epidemiological surveys more useful in the context of subsequent genome wide association (GWAS) research and post-GWAS investigations with a truly global health perspective.

The aim of the study was to estimate the physical activity (PA) level among the professional college students in North India. One hundred three professional college students in the age group of 18–25 years were recruited by simple random sampling for this cross-sectional online survey. The survey was advertised on the social networking sites (Facebook, WhatsApp) through a link www.surveymonkey.com/r/MG-588BY. A Short Form of International Physical Activity Questionnaire was used for this survey study. The questionnaire included total 8 questions on the basis of previous 7 days. The questionnaire consists of 3 main categories which were vigorous, moderate and high PA. Time spent in each activity level was multiplied with the metabolic equivalent of task (MET), which has previously set to 8.0 for vigorous activity, 4.0 for moderate activity, 3.3 for walking, and 1.5 for sitting. By multiplying MET with number of days and minutes performed weekly, amount of each activity level was calculated and measured as MET-min/wk. Further by adding MET minutes for each activity level, total MET-min/wk was calculated. Total number of 100 students participated in this study, and it was shown that all professional course students show different levels in PA. The total PA level among professional college students, which includes, physiotherapy, dental, medical, nursing, lab technician, pharmacy, management, law, engineering, were 434.4 (0–7,866), 170.3 (0–1,129), 87.7 (0–445), 102.8 (0–180), 469 (0–1,164), 0 (0–0), 645 (0–1,836), 337 (0–1,890), 396 (0–968) MET-min/wk respectively.

Booster seat use among school-aged children has been consistently lower than national goals. In this study, we sought to explore associations between parental experiences with booster seats and carpooling. We conducted a cross-sectional Web-based survey of a nationally representative panel of US parents in January 2010. As part of a larger survey, parents of 4- to 8-year-old children responded to 12 questions related to booster seats and carpooling. Of 1612 parents responding to the full survey (response rate = 71%), 706 had a 4- to 8-year-old child and 681 met inclusion rules. Most parents (76%) reported their child used a safety seat when riding in the family car. Of children reported to use seat belts, 74% did so in accordance with their state law. Parent report of child safety seat use was associated with younger child age and with the presence of state booster seat laws. Sixty-four percent of parents carpool. Among parents who carpool and whose children use a child safety seat: 79% indicated they would always ask another driver to use a booster seat for their child and 55% reported they always have their child use their booster seat when driving friends who do not have boosters. Carpooling is a common driving situation during which booster seat use is inconsistent. Social norms and self-efficacy are associated with booster seat use. Clinicians who care for children should increase efforts to convey the importance of using the size-appropriate restraint for every child on every trip.

Recently we applied the molecular convergent close-coupling (CCC) method to electron scattering from molecular hydrogen H2. Convergence of the major differential cross sections has been explicitly demonstrated in the fixed-nuclei approximation. A large close-coupling expansion that coupled highly excited states and ionization channels proved to be important to obtain convergent results. Here we present benchmark elastic and electronic excitation differential cross sections for b3Σu+ , a3Σg+ , c3Πu , B1Σu+ , EF1Σg+ , C1Πu , and e3Σu+ states and compare with available experiment and previous calculations.

This study aimed to determine the association between socioeconomic determinants and Chronic Respiratory Diseases (CRDs) in Thailand. The data were used from the National Socioeconomics Survey (NSS), a cross-sectional study conducted by the National Statistical Office (NSO), in 2010 and 2012. The survey used stratified two-stage sampling to select a nationally representative sample to respond to a structured questionnaire. A total of 17,040 and 16,905 individuals in 2010 and 2012, respectively, were included in this analysis. Multiple logistic regressions were used to identify the association between socioeconomic factors while controlling for other covariates. The prevalence of CRDs was 3.81% and 2.79% in 2010 and 2012, respectively. The bivariate analysis indicated that gender, family size, geographic location, fuels used for cooking and smoking were significantly associated with CRDs in 2010, whereas education, family size, occupation, region, geographic location, and smoking were significantly associated with CRDs in 2012. Both in 2010 and 2012, the multiple logistic regression indicated that the odds of having CRDs were significantly higher among those who lived in urban areas, females, those aged ≥41-50 or ≥61 yr old, and smokers when controlling for other covariates. However, fuels used for cooking, wood and gas, are associated with CRDs in 2010.

Few studies have addressed the practice of chiropractic care of children in Europe. No systematic classification of conditions currently exists in chiropractic pediatrics. The objective of this study was to investigate characteristics of clinical chiropractic practice, including the age of pediatric patients, the number of reports of negative side effects (NSEs), the opinions of doctors of chiropractic on treatment options by patient age groups, the conditions seen and the number of treatment sessions delivered by conditions and by patient age. An Internet cross-sectional survey was conducted in 20 European countries with 4109 doctors of chiropractic invited to reply. The 19 national associations belonging to the European Chiropractic Union and the Danish Chiropractic Association were asked to participate. Respondents were asked to self-report characteristics of their practices. Of the 956 (23.3%) participating chiropractors, 921 reported 19821 pediatric patients per month. Children represented 8.1% of chiropractors' total patient load over the last year. A total of 557 (534 mild, 23 moderate, and 0 severe) negative (adverse) side effects were reported for an estimated incidence of 0.23%. On the given treatment statements, chiropractors reported varying agreement and disagreement rates based on patient age. The 8309 answers on conditions were grouped into skeletal (57.0%), neurologic (23.7%), gastrointestinal (12.4%), infection (3.5%), genitourinary (1.5%), immune (1.4%), and miscellaneous conditions (0.5%). The number of treatment sessions delivered varied according to the condition and the patient age. This study showed that European chiropractors are active in the care of pediatric patients. Reported conditions were mainly skeletal and neurologic complaints. In this survey, no severe NSEs were reported, and mild NSEs were infrequent.

Population-based studies on sero-epidemiology of Rubella in women before conception are lacking. The aim of this study was to investigate the sero-prevalence of Rubella in a nationwide survey among Chinese women planning to get pregnant within six months. This population-based, cross-sectional, sero-survey of Rubella virus infection was a part of the National Free Preconception Health Examination Project covering all 31 provinces in Mainland China. Women intending to get pregnant within six months was enrolled between 2010 and 12. Information on demographic characteristics (age, residence status, race, education and occupation) and vaccination history was obtained by interviews. Rubella virus IgG sero-positivity was determined using venous blood samples. Of 2,120,131 women recruited to the study, Rubella virus IgG serology was available in 1,974,188 (99.3%). Participating women were of young age (median=28years), mostly engaged in agricultural activities (78%), and the majority (90%) had high school education or lower. The overall prevalence of Rubella virus IgG sero-positivity was 58.4% (1,161,129); geographical variation ranged from 92.5% in Jilin to 20.1% in Qinghai and 0.0% in Tibet. Only 4.6% (n=91,604) women reported to have had Rubella virus vaccination, and it varied from 18.6% (Guangdong) to 0.2% (Qinghai). Self-reported vaccination status did not correlate with Rubella virus IgG seropositivity. Prevalence of Rubella sero-positivity is low among Chinese women of reproductive age and there are significant regional differences. Over 40% of women being susceptible to Rubella in preconception period calls for a targeted screening and vaccination strategy. Copyright © 2017 Elsevier Ltd. All rights reserved.

Unmet needs and service satisfaction of victim support for the direct and indirect victims of serious violence: Results from a cross-sectional survey in Taiwan

PubMed Central

2018-01-01

Victim support services, in mature societies, aim to help victims recover after suffering a traumatic event. The effectiveness of victim support has traditionally been evaluated through rates of service utilization and incidence of psychopathology such as posttraumatic stress disorder. The current study, instead, inquires into service users’ unmet needs and satisfaction, and identifies factors that mediate such subjective measures, using data from a national cross-sectional survey on victims and surviving families of violent crime in Taiwan in 2011. The results reveal: 1) a gap between available and expected services, and 2) a correlation between service utilization and satisfaction, both consistent with previous studies. In addition, the current study identifies unsatisfied service users: They are homicidally bereaved, live with their spouse, suffer from post-crime financial distress and are still waiting for a court verdict on the incident. Victim support that helps victims heal through tailored services incorporating relationship counseling is proposed. PMID:29466463

2015-12-28

Absolute single-photoionization cross-section measurements for Se 2+ ions were performed at the Advanced Light Source at Lawrence Berkeley National Laboratory using the merged-beams photo-ion technique. Measurements were made at a photon energy resolution of 24 ± 3 meV in the photon energy range 23.5-42.5 eV, spanning the ground state and low-lying metastable state ionization thresholds. Here, to clearly resolve the resonant structure near the ground-state threshold, high-resolution measurements were made from 30.0 to 31.9 eV at a photon energy resolution of 6.7 ± 0.7 meV. Numerous resonance features observed in the experimental spectra are assigned and their energies and quantummore » defects tabulated. The high-resolution cross-section measurements are compared with large-scale, state-of-the-art theoretical cross-section calculations obtained from the Dirac Coulomb R -matrix method. Suitable agreement is obtained over the entire photon energy range investigated. In conclusion, these results are an experimental determination of the absolute photoionization cross section of doubly ionized selenium and include a detailed analysis of the photoionization resonance spectrum of this ion.« less

The prevalence of common skin infections in four districts in Timor-Leste: a cross sectional survey

PubMed Central

2010-01-01

Background Skin infections are a common public health problem in developing countries; however, they are rarely managed using a population based approach. Recent data on the burden of skin infections in Timor-Leste are limited. Our survey appears to be the only widespread survey conducted in more than 30 years and was designed to determine the baseline prevalence of some common skin infections in Timor-Leste. Methods We conducted a cross sectional survey in 14 sites including community health clinics, schools and hospitals within four different geographical regions. Participants were examined for five conditions (scabies, pyoderma, fungal infections, leprosy and yaws) by a multidisciplinary team. Analyses were conducted using EpiInfo version 6.04d. Results We examined the skin of 1535 participants aged between four months and 97 years. The majority of participants were male, aged between 11 and 20 years and had at least one condition of interest (56.0%, 56.0%, and 63.1%, respectively). Fungal infections were the most common presentation (39.0%) and males were more commonly affected than females (42.3% vs 34.0%, respectively, pvalue < 0.0001). Among those people with more than one condition the two most common co-infections were scabies with either pyoderma or a fungal infection (38.0% and 32.0%, respectively). The survey identified 29 previously undiagnosed cases of leprosy and six cases of yaws. Conclusions Our findings indicate the need for a comprehensive programme to address these conditions. There are successful disease control programmes in place within the country and it is hoped a healthy skin programme could be integrated into an established disease control programme in order to maximise health benefits and resources.

Antiretroviral (ARV) drug treatment benefits the treated individual and can prevent HIV transmission. We assessed ARV drug use in a community-randomized trial that evaluated the impact of behavioral interventions on HIV incidence. Samples were collected in a cross-sectional survey after a 3-year intervention period. ARV drug testing was performed using samples from HIV-infected adults at 4 study sites (Zimbabwe; Tanzania; KwaZulu-Natal and Soweto, South Africa; survey period 2009-2011) using an assay that detects 20 ARV drugs (6 nucleoside/nucleotide reverse transcriptase inhibitors, 3 nonnucleoside reverse transcriptase inhibitors, and 9 protease inhibitors; maraviroc; raltegravir). ARV drugs were detected in 2011 (27.4%) of 7347 samples; 88.1% had 1 nonnucleoside reverse transcriptase inhibitors ± 1-2 nucleoside/nucleotide reverse transcriptase inhibitors. ARV drug detection was associated with sex (women>men), pregnancy, older age (>24 years), and study site (P < 0.0001 for all 4 variables). ARV drugs were also more frequently detected in adults who were widowed (P = 0.006) or unemployed (P = 0.02). ARV drug use was more frequent in intervention versus control communities early in the survey (P = 0.01), with a significant increase in control (P = 0.004) but not in intervention communities during the survey period. In KwaZulu-Natal, a 1% increase in ARV drug use was associated with a 0.14% absolute decrease in HIV incidence (P = 0.018). This study used an objective, biomedical approach to assess ARV drug use on a population level. This analysis identified factors associated with ARV drug use and provided information on ARV drug use over time. ARV drug use was associated with lower HIV incidence at 1 study site.

Cross-sections are often constructed from data to create a visual impression of the geologist's interpretation of the sub-surface geology. However as with all interpretations, this vision of the sub-surface geology is uncertain. We have designed and carried out an experiment with the aim of quantifying the uncertainty in geological cross-sections created by experts interpreting borehole data. By analysing different attributes of the data and interpretations we reflect on the main controls on uncertainty. A group of ten expert modellers at the British Geological Survey were asked to interpret an 11.4 km long cross-section from south-east Glasgow, UK. The data provided consisted of map and borehole data of the superficial deposits and shallow bedrock. Each modeller had a unique set of 11 boreholes removed from their dataset, to which their interpretations of the top of the bedrock were compared. This methodology allowed quantification of how far from the 'correct answer' each interpretation is at 11 points along each interpreted cross-section line; through comparison of the interpreted and actual bedrock elevations in the boreholes. This resulted in the collection of 110 measurements of the error to use in further analysis. To determine the potential control on uncertainty various attributes relating to the modeller, the interpretation and the data were recorded. Modellers were asked to fill out a questionnaire asking for information; such as how much 3D modelling experience they had, and how long it took them to complete the interpretation. They were also asked to record their confidence in their interpretations graphically, in the form of a confidence level drawn onto the cross-section. Initial analysis showed the majority of the experts' interpreted bedrock elevations within 5 metres of those recorded in the withheld boreholes. Their distribution is peaked and symmetrical about a mean of zero, indicating that there was no tendency for the experts to either under

2013-01-01

Background Previous studies suggest that obesity is associated with higher prostate cancer progression and mortality despite an association with lower prostate cancer incidence. This study aims to better understand these apparently inconsistent relationships among obese men, by combining evidence from three nationally representative cross-sectional surveys. Methods We evaluated relationships between obesity and (1) testosterone concentrations in the Third National Health and Nutrition Examination Survey (NHANES III; n=845), (2) prostate-specific antigen (PSA) in NHANES 2001–2004 (n=2,458) and (3) prostate biopsy rates in the National Health Interview Survey (NHIS 2000; n=4,789) population. Mean testosterone, PSA concentrations and biopsy rates were computed for body mass index (BMI) categories. Results Testosterone concentrations were inversely associated with obesity (p-trend<0.0001) in NHANES III. In NHANES 2001–2004 obese (BMI >35) versus lean (BMI <25) men were less likely to have PSA concentrations that reached the biopsy threshold of >4 ng/ml (3% versus 8%; p<0.0001). Among NHIS participants all BMI groups had similar rates of PSA testing (p=0.24). However, among men who had PSA tests, 11% of men with BMI >30 versus 16% with BMI <25, achieved a PSA threshold of 4 ng/ml; p=0.01. Furthermore, biopsy rates were lower among men with BMI >30 versus BMI <25 in NHIS participants (4.6% vs. 5.8%; p=0.05). Conclusions Obesity was associated with lower PSA-driven biopsy rates. These data support further studies to test the hypothesis that obesity affects prostate cancer detection independent of prostate cancer risk by decreasing the PSA-driven biopsy rates. PMID:20800152

Journal clubs have been traditionally incorporated into academic training programs to enhance competency in the interpretation of literature. We designed a structured journal club (JC) to improve skills in the interpretation of literature; however, we were not aware of how learners (interns, residents, clinical pharmacists, etc.) would perceive it. We aimed to assess the perception of learners at different levels of pharmacy training. A cross-sectional design was used. A self-administered online survey was emailed to JC attendees from 2010–2014 at King Abdulaziz Medical City, Jeddah, Saudi Arabia. The survey questions included: introduction sessions, topic selection, JC layout, interaction with the moderator, and decision-making skills by clinical pharmacists. The response rate was 58/89 (65%); 52/54 (96%) respondents believed that JC adds to their knowledge in interpreting literature. Topic selection met the core curriculum requirements for credentials exams for 16/36 (44.4%), while 16/22 (73%) presenters had good to excellent interaction with the moderator. JC facilitated decision-making for 10/12 (83%) of clinical pharmacists. The results suggest that clinical pharmacist-steered JC may serve as an effective tool to empower learners at different levels of pharmacy practice, with evidence-based principles for interpretation of literature and guide informed decision-making.

The present study aimed to determine major factors that influence blood donation in China. Factors affecting blood donation often vary in various populations. This cross-sectional study used self-administered, standardised, structured questionnaires to survey selected donors and non-donors in Guangzhou, China between 10 December 2013 and 25 June 2014. Among the 1080 questionnaires collected, 1034 (95·7%) questionnaires were valid for this analysis, including 602 donors and 432 non-donors. Results revealed that helping patients (n = 405, 68·2%) was the main objective of blood donation, and self-perception of poor health (n = 138, 33·1%) was the main reason for not donating. Responses to questions raised by donors and inquiring about a donor's physical condition were thought to be the most important blood donation routines (n = 302, 65·5%). For non-donors, 90·3% (n = 390) expressed their intention to donate blood in the future, and usage of blood (n = 182, 46·7%) was the most asked question. Prepaid cellular phone cards were the most popular incentives. Raising the awareness of blood donation was the most effective way of enhancing blood donation programmes, and television ads and the internet were the most effective means. Helping patients was the main objective of blood donation in China. However, self-perception of poor health was a major barrier to donating blood. Raising the awareness of blood donation in combination with multiple aspects of campaigns that target different populations with potential blood donors is critical. Television and the internet are the most effective tools for promotion of and recruitment for blood donation. © 2017 British Blood Transfusion Society.

The study aimed to explore how nurses and midwives obtain, use and embed evidence in everyday practice. The study design was cross-sectional survey method. The setting was one local health district in metropolitan Sydney, Australia. All nurses and midwives working within the local health district, with access to an email account, were invited to participate in the study. An online survey questionnaire was distributed to explore how evidence is obtained, used and embedded within the clinical setting. The data were analysed using descriptive statistics (frequency and percentages). Pearson's Chi-square tests were used for comparison between groups. There were 204 survey respondents. The findings identified that the majority (n = 157; 76.96%) of respondents obtained evidence primarily from clinical practice guidelines. The majority (n = 149; 73.04%) of respondents reportedly searched databases and used evidence related to general clinical practice. There was a statistical difference (χ = 17.069; df = 8; P = 0.029) when comparing leadership positions and other registered practitioner groups in the frequency of searching for evidence. Most respondents (n = 138; 67.65%) were confident in their ability to change practice on the basis of available evidence. Thematic analysis identified four barriers to sustaining evidence-based practice, which included: the need for time; the need for organizational and management support; the need for educational opportunities and challenges to accessing evidence. The study provided an understanding of how nurses and midwives obtain, use and embed evidence into everyday practice. More importantly, the role of leadership is significant to support a process of knowledge generation, research translation and the implementation of evidence into clinical settings.

Moral distress is associated with job dissatisfaction, turnover and early retirement. Because of these negative consequences moral distress should be reduced. Little research has been done on what job factors contribute to whether or not a situation causes moral distress. To identify individual and job characteristics associated with moral distress in nursing staff. This is a cross sectional correlational study. Nursing staff members completed two survey questionnaires with a time-interval of 3 months. In the first survey questions were asked about job characteristics and job satisfaction. Three months afterwards the respondents answered questions on moral distress. 365 nursing staff members employed in nursing homes, homes for the elderly, home care and acute care hospitals completed both questionnaires. High moral distress levels were related to lower job satisfaction. Moral distress is higher when nurses perceive less time available to give care to patients. If satisfaction with the consultation possibilities within the team is low and when an instrumental leadership style exists, nursing staff members are also more likely to experience moral distress. Nursing staff members working 30-40h per week experience less moral distress than colleagues working fewer hours per week. Multivariate analyses showed no relations with other individual characteristics measured. Job characteristics that contribute to moral distress should be an issue for managers because it is related to job satisfaction. Interventions to reduce moral distress should target at organisational issues. The way a team is supported can raise or decrease moral distress levels. Copyright © 2012 Elsevier Ltd.

Carpal tunnel syndrome (CTS) is the most common compressive entrapment neuropathy caused by the compression of the median nerve at the wrist space known as the carpal tunnel. The epidemiologic factors related to CTS include genetic, medical, social, vocational, and demographic factors. The common symptoms experienced include pain, paresthesia, and numbness in the median nerve distribution. If left untreated, it can lead to irreversible median nerve damage, causing a loss of hand function. Body mass index (BMI) has been attributed as a risk factor for the development of CTS. We planned to determine the frequency of obesity among CTS patients in the neurophysiology department of a tertiary care center in Islamabad, Pakistan. The survey was designed as a cross-sectional descriptive study from March 2016 to August 2016 using a consecutive nonprobability sampling technique. A total of 112 patients with a mean age of 54 ± 5 years were included in the study. In the study population, 39 patients (35 percent) were males and 73 were females (65 percent). Based on BMI, 74 patients (66 percent) had a normal weight and 38 (34 percent) were obese. The frequency of obesity in our study was 34 percent, excluding the other comorbid conditions, which is quite high. Targeted therapy in those with CTS should also include weight reduction measures because obesity poses a cause-and-effect relationship for both the severity and the pathogenesis of CTS.

Old Order Amish and Mennonites, or Plain populations, are a growing minority in North America with unique health care delivery and access challenges coupled with higher frequencies of genetic disorders. The objective of this study was to determine newborn screening use and attitudes from western Wisconsin Plain communities. A cross-sectional survey, with an overall response rate of 25 %, provided data representing 2010 children. In households with children (n = 297), the rate of newborn screening was 74 % and all children were screened in 40 % of these households. Lack of access to testing was the most common reason for not screening all children and parental age was inversely associated with testing. The majority of respondents reported some or more knowledge of screening, viewed screening as important, and had access to screening in their communities. Households with children who had never received newborn screening (26 %) reported lower frequencies of favorable responses in all categories compared to households that had at least one child screened. The difference in access to newborn screening was less marked between the groups compared to differences on knowledge and consideration of its importance. Moreover, 55 % of households who had never screened any of their children reported being unlikely or unsure of screening any future children. A focus on improving access to newborn screening alongside establishing approaches to change parental perceptions on the importance of newborn screening is necessary for increasing newborn screening in these Plain communities.

(1) To assess Jordanian ICU patients' pain characteristics (intensity and interference) and levels of pain management satisfaction; and (2) to determine potential predictors of pain management satisfaction among ICU patients. A descriptive cross-sectional design was utilised using the American Pain Society-Patient Outcome Questionnaire to survey 139 Jordanian ICU patients from different health care sectors in Jordan. High levels of pain and pain interferences were reported by participants, which were higher than those reported by previous studies in other countries. However, participants were relatively satisfied with pain management approaches. Also, the results showed a predictive model of three potential predictors, which accounted for 36% of the variance in participants' satisfaction with pain management (adjusted R(2)=0.36, F=12.14, df=7129, p<0.005). The strongest predictor to participants' satisfaction with pain management was time needed to get analgesia (beta=-0.480, p<0.001), followed by average pain interference (beta=0.218, p=0.02), and being told about importance of reporting pain (beta=0.198, p=0.006). Jordanian ICU patients reported high pain levels, which supports the need for applying a caring attitude in managing patients' pain reports. Also, such a study is among the first pain management studies in Jordan aiming at setting the stage for future research studies. Finally, results can be included in planning pain management strategies and protocols within hospitals. Copyright © 2014 Australian College of Critical Care Nurses Ltd. Published by Elsevier Ltd.

Objective To assess the responses of physicians to providing emergency medical assistance outside of routine clinical care. We assessed the percentage who reported previous Good Samaritan behaviour, their responses to hypothetical situations, their comfort providing specific interventions and the most likely reason they would not intervene. Setting Physicians residing in North Carolina. Participants Convenience sample of 1000 licensed physicians. Intervention Mailed survey. Design Cross-sectional study conducted May 2015 to September 2015. Main outcome and measures Willingness of physicians to act as Good Samaritans as determined by the last opportunity to intervene in an out-of-office emergency. Results The adjusted response rate was 26.1% (253/970 delivered). 4 out of 5 physicians reported previous opportunities to act as Good Samaritans. Approximately, 93% reported acting as a Good Samaritan during their last opportunity. There were no differences in this outcome between sexes, practice setting, specialty type or experience level. Doctors with greater perceived knowledge of Good Samaritan law were more likely to have intervened during a recent opportunity (p=0.02). The most commonly cited reason for potentially not intervening was that another health provider had taken charge. Conclusions We found the frequency of Good Samaritan behaviour among physicians to be much higher than reported in previous studies. Greater helping behaviour was exhibited by those who expressed more familiarity with Good Samaritan law. These findings suggest that physicians may respond to legal protections. PMID:26966061

Work-family conflict (WFC) may have negative effects on workers' health and productivity. The objective of this analysis was to assess the association between WFC and mental disorders that occurred in the past month. Data from the U.S. National Comorbidity Survey were used. The 1-month prevalence of mental disorders was estimated by levels of WFC and by gender. Compared to participants who reported low WFC, those who reported high WFC had a significantly higher prevalence of mental and/or substance use related disorders in the past month. Working hours and domestic roles did not have significant impacts on the association between WFC and mental disorders, irrespective of gender. Work and family roles and the balance between the two are important for workers' mental health. The influence of WFC on mental health should be investigated in conjunction with important work environment characteristics in longitudinal studies.

Objective HIV testing is mandatory in re-education-through-labour camps (laojiaosuo) in China yet no studies have reported on the process. Methods The survey response rate was 100% although 29 detainees were excluded because they were under 18 years of age. A cross-sectional face-to-face survey was conducted in three labour camps in Guangxi, located in the south-western region of China. Results Of the 755 detainees surveyed, 725 (96%) reported having a blood test in the labour camps of whom 493 (68%) thought this included an HIV test. 61 detainees self-reported they were HIV infected, their status confirmed by medical records, if available. Of these, 53 (87%) recalled receiving post-test HIV education, and 15 (25%) were currently receiving HIV antiretroviral therapy. Pretest education on HIV was provided to 233/725 (32%) detainees. The study further reports on detainees’ reactions and feelings towards non-disclosure and disclosure of their HIV test results in the labour camps. Conclusions Mandatory testing is almost universal in the labour camps although a proportion of detainees were unaware that this included an HIV test. HIV test results should be disclosed to all labour camp detainees to reduce their distress of not knowing and prevent misconceptions about their HIV status. Labour camps provide another opportunity to implement universal treatment (‘Test and Treat’) to prevent the spread of HIV. PMID:25739879

The Client Satisfaction Questionnaire (CSQ-8) is one of a limited number of standardised satisfaction measures that have been used widely across mental health services. This study examined the CSQ-8 as a measure of general satisfaction within residential substance abuse treatment. It compared the CSQ-8 with another established measure of client satisfaction that was developed for substance abuse treatment settings (Treatment Perceptions Questionnaire, TPQ). It also sought to examine the relationship between the CSQ-8 and commonly used process measures. Cross-sectional data was collected from across 14 Australian residential medium-to-long term alcohol and other drug treatment facilities (N = 1378). Demographic, substance abuse and mental health characteristics were collected, as well as process measures of craving, general functioning, self-perceptions, recovery and symptom distress. A confirmatory factory analysis established that the CSQ-8 retains a single factor. The scale was strongly correlated with the TPQ, suggesting high concurrent validity. However, while the TPQ was normally distributed, the CSQ-8 was highly negatively skewed. Significant associations were found between the CSQ-8 and cross-sectional process measures. Results suggest that that CSQ-8 is an appropriate measure to be used in residential substance abuse treatment settings. However, because of the high levels of negative skew, it is likely that the TPQ is more accurate in capturing clients' dissatisfaction than the CSQ-8. Future research should include longitudinal studies of satisfaction in order to examine how changes in satisfaction may be related to client characteristics, outcome measures, dropout or re-engagement in treatment.

Practical nurses have experienced an increasing scope of practice, including an expectation to care for complex patients and function on interdisciplinary teams. Little is known about the degree to which patient safety principles are addressed in practical nursing education. To examine self-reported patient safety competencies of practical nurses. A cross-sectional online survey (July 2014) and face-to-face interviews (June 2015). Ontario, Canada. Survey participants were practical nurses newly registered with the College of Nurses of Ontario between January 2012 and December 2013. Interview participants were faculty and students in a practical nursing program in Ontario. Survey respondents completed the Health Professional Education in Patient Safety Survey online. Self-reported competencies in various patient safety domains were compared between classroom and clinical settings. Faculty members were interviewed about educational preparation of practical nurses and students were interviewed to provide insight into interpretation of survey questions. The survey response rate was 28.4% (n=1104/3883). Mean domain scores indicated a high level of confidence in patient safety competence (<4.0/5.0). Confidence was highest in respondents registered with the College of Nurses of Ontario >2years and in those who obtained their education outside of Canada. Faculty believed their approach to teaching and learning instilled a deep understanding of the limits to practical nurse autonomous practice. Practical nurses were confident in what they learned about patient safety in their educational programs. The high degree of patient safety competence may be a true reflection of practical nurses understanding of, and comfort with, the limits of their knowledge and, ultimately, the limits of their individual autonomous practice. Further exploration as to whether the questionnaire requires additional modification for use with practical nurse populations is warranted. However, this

MC 2 -3: Multigroup Cross Section Generation Code for Fast Reactor Analysis

Lee, Changho; Yang, Won Sik

This paper presents the methods and performance of the MC2 -3 code, which is a multigroup cross-section generation code for fast reactor analysis, developed to improve the resonance self-shielding and spectrum calculation methods of MC2 -2 and to simplify the current multistep schemes generating region-dependent broad-group cross sections. Using the basic neutron data from ENDF/B data files, MC2 -3 solves the consistent P1 multigroup transport equation to determine the fundamental mode spectra for use in generating multigroup neutron cross sections. A homogeneous medium or a heterogeneous slab or cylindrical unit cell problem is solved in ultrafine (2082) or hyperfine (~400more » 000) group levels. In the resolved resonance range, pointwise cross sections are reconstructed with Doppler broadening at specified temperatures. The pointwise cross sections are directly used in the hyperfine group calculation, whereas for the ultrafine group calculation, self-shielded cross sections are prepared by numerical integration of the pointwise cross sections based upon the narrow resonance approximation. For both the hyperfine and ultrafine group calculations, unresolved resonances are self-shielded using the analytic resonance integral method. The ultrafine group calculation can also be performed for a two-dimensional whole-core problem to generate region-dependent broad-group cross sections. Verification tests have been performed using the benchmark problems for various fast critical experiments including Los Alamos National Laboratory critical assemblies; Zero-Power Reactor, Zero-Power Physics Reactor, and Bundesamt für Strahlenschutz experiments; Monju start-up core; and Advanced Burner Test Reactor. Verification and validation results with ENDF/B-VII.0 data indicated that eigenvalues from MC2 -3/DIF3D agreed well with Monte Carlo N-Particle5 MCNP5 or VIM Monte Carlo solutions within 200 pcm and regionwise one-group fluxes were in good agreement with Monte Carlo

The reaction 23Na(p, γ)24Mg can provide a link from the NeNa to the MgAl cycle in stellar burning and is therefore of interest in nuclear astrophysics. To determine the reaction rates at stellar temperatures, new cross section measurements at low proton energies have been performed recently, and further experiments are underway. The current cross section data implies that the reaction rate up to temperatures of 1 GK is determined by a few narrow resonances and direct capture. Complementary to these experimental efforts at low proton energies, cross section measurements at higher energies can help to constrain the direct capture and broad resonance contributions to the cross section and reduce the uncertainty of the extrapolation towards stellar energies. In this paper we report an experiment to measure the 23Na(p, γ)24Mg cross section with a solid target setup at the St. ANA 5U accelerator at the University of Notre Dame. The experiment and the current status of data analysis will be described.

This study assessed drinking water quality, sanitation, and hygiene (WASH) conditions among 708 schoolchildren and 562 households in Dolakha and Ramechhap districts of Nepal. Cross-sectional surveys were carried out in March and June 2015. A Delagua water quality testing kit was employed on 634 water samples obtained from 16 purposively selected schools, 40 community water sources, and 562 households to examine water quality. A flame atomic absorption spectrophotometer was used to test lead and arsenic content of the same samples. Additionally, a questionnaire survey was conducted to obtain WASH predictors. A total of 75% of school drinking water source samples and 76.9% point-of-use samples (water bottles) at schools, 39.5% water source samples in the community, and 27.4% point-of-use samples at household levels were contaminated with thermo-tolerant coliforms. The values of water samples for pH (6.8–7.6), free and total residual chlorine (0.1–0.5 mg/L), mean lead concentration (0.01 mg/L), and mean arsenic concentration (0.05 mg/L) were within national drinking water quality standards. The presence of domestic animals roaming inside schoolchildren’s homes was significantly associated with drinking water contamination (adjusted odds ratio: 1.64; 95% confidence interval: 1.08–2.50; p = 0.02). Our findings call for an improvement of WASH conditions at the unit of school, households, and communities. PMID:28106779

To investigate the relationship between turnover intentions and job satisfaction among hospital midwives from seven countries and to determine how the related variables differ between countries. Studies investigating professional turnover and job satisfaction among midwives are limited in scope. A cross-sectional descriptive survey was used to investigate the intended turnover and job satisfaction relationship among 1190 hospital midwives in European and Asian countries. Data were collected using a set of questionnaires that included questions regarding the leaving intentions of midwives and the McCloskey/Mueller satisfaction scale. Midwives were least satisfied with their extrinsic rewards and professional opportunities and with the balance between family and work. Significant differences were found in all domains of job satisfaction according to midwives' intentions to leave their current workplace in hospital or profession of midwife, and to work abroad. There are some general satisfying and dissatisfying elements for the profession of midwife across different countries. The results highlight the importance of understanding midwives' leaving intentions and related factors across different countries. To prevent midwife turnover, health-care managers should gain greater insight into the early stage of midwives' turnover intention. © 2015 John Wiley & Sons Ltd.

Healthcare workers who have received disaster preparedness education are more likely to report a greater understanding of disaster preparedness. However, research indicates that current nursing curricula do not adequately prepare nurses to respond to disasters. This is the first study to assess Asia-Pacific nurses' perceptions about their level of disaster knowledge, skills, and preparedness. A cross-sectional survey was conducted with 757 hospital and community nurses in seven Asia-Pacific countries. Data were collected using the modified Disaster Preparedness Evaluation Tool. Participants were found to have overall low-to-moderate levels of disaster knowledge, skills and preparedness, wherein important gaps were identified. A majority of the variance in disaster preparedness scores was located at the level of the individual respondent, not linked to countries or institutions. Multilevel random effects modelling identified disaster experience and education as significant factors of positive perceptions of disaster knowledge, skills, and management. The first step toward disaster preparedness is to ensure frontline health workers are able to respond effectively to disaster events. The outcomes of this study have important policy and education implications. © 2015 Wiley Publishing Asia Pty Ltd.

Objective: To evaluate the perceptions and attitudes of waterpipe (shisha) smokers in Qatar regarding the health risks associated with addiction and to determine their intentions to quit. Methods: A cross-sectional survey was conducted among 181 self-reported waterpipe smokers. Participants were approached in public places as well as in shisha cafes in Qatar. The questionnaire included items related to perception, attitude and intention to quit. Both descriptive and inferential statistics were performed for data analyses, with P ≤ 0.05 considered statistically significant. Results: About 44% of the respondents believed that waterpipe smoking was safer than cigarette smoking, and more than 70% would not mind if their children became involved in waterpipe smoking. More than half of the current smokers wanted to quit smoking shisha at some point, and 17% identified health concerns as the main motivating factor for their intention to quit. Conclusion: A large proportion of shisha smokers viewed shisha as a safer alternative to cigarettes, yet they admitted to intending to quit. These findings underscore the need to design educational interventions and awareness campaigns as well as impose stringent laws on waterpipe smoking in public places in Qatar. PMID:27051611

Accurate neutron-capture cross sections on unstable nuclei near the line of beta stability are crucial for understanding the s-process nucleosynthesis. However, neutron-capture cross sections for short-lived radionuclides are difficult to measure due to the fact that the measurements require both highly radioactive samples and intense neutron sources. Essential ingredients for describing the γ decays following neutron capture are the γ-ray strength function and level densities. We will compare different indirect approaches for obtaining the most relevant observables that can constrain Hauser-Feshbach statistical-model calculations of capture cross sections. Specifically, we will consider photon scattering using monoenergetic and 100% linearly polarized photon beams. Challenges that exist on the path to obtaining neutron-capture cross sections for reactions on isotopes near and far from stability will be discussed.

The purpose of this study is to examine the relationship between the number of unintended pregnancies and current contraceptive use. This is a secondary analysis of a cross-sectional survey, the 2006-2008 National Survey of Family Growth, which included 4,052 women between the ages of 15 and 44 years. A statistically significant association was found between the nonuse of contraceptives and repeated unintended pregnancies, as well as among those who used an effective contraceptive method and repeated unintended pregnancies. Nurses are encouraged to ask questions about intendedness of pregnancies during women's visits and help women choose appropriate contraceptive methods.

Contextual influences on environmental concerns cross-nationally: A multilevel investigation.

PubMed

Marquart-Pyatt, Sandra T

2012-09-01

Environmental issues continue to grow in international prominence, as environmental conditions are recognized as some of the most important problems facing the world. Research examining this globalization of environmental concern shown in public opinion surveys emphasizes the importance of context yet is currently underspecified. To address this gap, this research uses a multi-level, cross-national study to examine individual-level and country-level influences on three measures of environmental concern: environmental threat awareness, environmental efficacy, and willingness to pay. At the individual level, education, age, and gender affect environmental concerns. At the national level, economic, political, and environmental factors affect environmental concerns. Importantly, contextual factors differ in their effects depending on the dimension of environmental concern measured. Results from cross-level interactions for education confirm these complexities across these measures, supporting a dimensionality argument. The importance of the measurement of environmental concern shown in this research is emphasized for future cross-national scholarship. Copyright © 2012 Elsevier Inc. All rights reserved.

Food processing alters food from its natural state for safety, convenience, taste or palatability. Previous research suggests that industrially processed foods, and diets high in these products, tend to be less healthful. However, most previous work is based on household, rather than individual-level, data. Little has been reported on the relationship between processed food consumption and markers of health; or on socio-demographic correlates of processed food consumption. Our objective was to describe: the nutritional content of foods classified according to degree of processing; the nutritional content of diets with different relative intakes of processed foods; the socio-demographic characteristics of individuals with different relative intakes of processed foods; and the association between intake of processed foods and body weight. Secondary analysis of data from the UK National Diet and Nutrition Survey (2008-12), a large national cross-sectional study of diet. Dietary information was collected using four-day, unweighed, food-diaries. Foods were classified as: unprocessed or minimally processed (MPF; foods with no processing or mostly physical processes applied to single whole foods), processed ingredients (PI; extracted and purified components of single whole foods), or ultra-processed food products (UPF; products produced from industrial combining of MPF and PI). Two thousand one hundred seventy four adults were included. MPF and diets high in these foods, had the most healthful nutritional profile. UPF did not necessarily have the least healthful nutritional profile, but diets high in these foods did. Women, and older adults consumed more energy from MPF, and less from UPF. Those living in lower occupation social class households consumed less energy from MPF, but no more from UPF. Only higher intake of PI was consistently, inversely, associated with body weight. This is the first study to explore correlates of processed food consumption, using individual

Transfusion practice might significantly influence patient morbidity and mortality. Between European countries, transfusion practice of red blood cells (RBC) greatly differs. Only sparse data are available on transfusion practice of general internal medicine physicians in Switzerland. In this cross-sectional survey, physicians working in general medicine teaching hospitals in Switzerland were investigated regarding their self-reported transfusion practice in anemic patients without acute bleeding. The definition of anemia, transfusion triggers, knowledge on RBC transfusion, and implementation of guidelines were assessed. 560 physicians of 71 hospitals (64%) responded to the survey. Anemia was defined at very diverging hemoglobin values (by 38% at a hemoglobin <130 g/L for men and by 57% at <120 g/L in non-pregnant women). 62% and 43% respectively, did not define anemia in men and in women according to the World Health Organization. Fifty percent reported not to transfuse RBC according to international guidelines. Following factors were indicated to influence the decision to transfuse: educational background of the physicians, geographical region of employment, severity of anemia, and presence of known coronary artery disease. 60% indicated that their knowledge on Transfusion-related Acute Lung Injury (TRALI) did not influence transfusion practice. 50% of physicians stated that no local transfusion guidelines exist and 84% supported the development of national recommendations on transfusion in non-acutely bleeding, anemic patients. This study highlights the lack of adherence to current transfusion guidelines in Switzerland. Identifying and subsequently correcting this deficit in knowledge translation may have a significant impact on patient care.

Fiji, an upper-middle income state in the Pacific Ocean, has experienced an increase in confirmed case notifications of enteric fever caused by Salmonella enterica serovar Typhi (S. Typhi). To characterize the epidemiology of typhoid exposure, we conducted a cross-sectional sero-epidemiological survey measuring IgG against the Vi antigen of S. Typhi to estimate the effect of age, ethnicity, and other variables on seroprevalence. Epidemiologically relevant cut-off titres were established using a mixed model analysis of data from recovering culture-confirmed typhoid cases. We enrolled and assayed plasma of 1787 participants for anti-Vi IgG; 1,531 of these were resident in mainland areas that had not been previously vaccinated against S. Typhi (seropositivity 32.3% (95%CI 28.2 to 36.3%)), 256 were resident on Taveuni island, which had been previously vaccinated (seropositivity 71.5% (95%CI 62.1 to 80.9%)). The seroprevalence on the Fijian mainland is one to two orders of magnitude higher than expected from confirmed case surveillance incidence, suggesting substantial subclinical or otherwise unreported typhoid. We found no significant differences in seropositivity prevalences by ethnicity, which is in contrast to disease surveillance data in which the indigenous iTaukei Fijian population are disproportionately affected. Using multivariable logistic regression, seropositivity was associated with increased age (odds ratio 1.3 (95% CI 1.2 to 1.4) per 10 years), the presence of a pit latrine (OR 1.6, 95%CI 1.1 to 2.3) as opposed to a septic tank or piped sewer, and residence in settlements rather than residential housing or villages (OR 1.6, 95% CI 1.0 to 2.7). Increasing seropositivity with age is suggestive of low-level endemic transmission in Fiji. Improved sanitation where pit latrines are used and addressing potential transmission routes in settlements may reduce exposure to S. Typhi. Widespread unreported infection suggests there may be a role for typhoid

Swiss primary care (PC) is facing workforce shortage. Up to 2011 this workforce was supplied by two board certifications: general medicine and internal medicine. To strengthen them against subspecialties, they were unified into one: general internal medicine. However, since unification general practitioners' career options are no longer restrained by early commitment to PC. This may lead to a decrease of future primary care physicians (PCPs). To gain insights in timing and factors influencing career choice of internists, we addressed a cross sectional survey to all board certified internists in the years 2000-2010 (n = 1462). Main measures were: final career choice (PCPs, hospital internists or subspecialists), timing and factors influencing career choice, and attractiveness of PCP career during medical school and residency. Response rate was 53.2%, 44.8% were female and median age was 45 years old. Final career choice was PCP for 39.1% of participants, 15.0% chose to become hospital internists, 41.8% became subspecialists and 4.0% other. Timing of career choice significantly differed between groups. Most of the subspecialists have chosen their career during residency (65.3%), while only 21.9% of the PCPs chose during residency. Work experience in an academic hospital was negatively associated with becoming PCP (P < 0.001). Family influence on career choice was more frequently reported among PCPs and chiefs' influence more reported among non-PCPs (P < 0.001). Fifty-nine percent of the participants considered a career as PCP to be attractive during medical school, this proportion decreased over time. Timing of career choice of PCPs and subspecialists strongly differed. PCPs opted late for their career and potentially modifiable external factors seem to contribute to their decision. This stresses the importance of fostering attractiveness of PC during medical school as well as during and after residency and of tailored residency positions for future PCPs

Cross-Sectional Analysis of Longitudinal Mediation Processes.

Statistical mediation analysis can help to identify and explain the mechanisms behind psychological processes. Examining a set of variables for mediation effects is a ubiquitous process in the social sciences literature; however, despite evidence suggesting that cross-sectional data can misrepresent the mediation of longitudinal processes, cross-sectional analyses continue to be used in this manner. Alternative longitudinal mediation models, including those rooted in a structural equation modeling framework (cross-lagged panel, latent growth curve, and latent difference score models) are currently available and may provide a better representation of mediation processes for longitudinal data. The purpose of this paper is twofold: first, we provide a comparison of cross-sectional and longitudinal mediation models; second, we advocate using models to evaluate mediation effects that capture the temporal sequence of the process under study. Two separate empirical examples are presented to illustrate differences in the conclusions drawn from cross-sectional and longitudinal mediation analyses. Findings from these examples yielded substantial differences in interpretations between the cross-sectional and longitudinal mediation models considered here. Based on these observations, researchers should use caution when attempting to use cross-sectional data in place of longitudinal data for mediation analyses.

Understanding and Predicting Social Media Use Among Community Health Center Patients: A Cross-Sectional Survey

PubMed Central

2014-01-01

Background The use of social media by health care organizations is growing and provides Web-based tools to connect patients, caregivers, and providers. Objective The aim was to determine the use and factors predicting the use of social media for health care–related purposes among medically underserved primary care patients. Methods A cross-sectional survey was administered to 444 patients of a federally qualified community health center. Results Community health center patients preferred that their providers use email, cell phones for texting, and Facebook and cell phone apps for sharing health information. Significantly more Hispanic than white patients believed their providers should use Facebook (P=.001), YouTube (P=.01), and Twitter (P=.04) for sharing health information. Use and intentions to use social media for health-related purposes were significantly higher for those patients with higher subjective norm scores. Conclusions Understanding use and factors predicting use can increase adoption and utilization of social media for health care–related purposes among underserved patients in community health centers.

To describe the degree of community support - and factors associated with this support - for a number of potential transport policy options among an inner-city sample of residents in Sydney, Australia. This study analysed data collected from a cross-sectional online survey: Wave 3 of the Sydney Transport and Health Study, conducted in September-October 2015 (n=418). There was a high level of overall support for policies to make public transport cheaper (85%), have more bicycle paths separated from motor vehicles (82%) and have a public bike-share program (72%), with similar levels of support across usual commute mode, age and sex. Despite a natural tendency for respondents to support transport policies that were of most relevance to themselves, it appeared that, in this sample, public support for public transport and bicycling policies remained strong across all respondents. Implications for public health: Policies that support public transport and active travel and achieve positive health outcomes would be well received by inner-Sydney residents. © 2018 The Authors.

Generalized anxiety disorder (GAD) is poorly understood compared with other anxiety disorders, and debates persist about the seriousness of this disorder. Few data exist on GAD outside a small number of affluent, industrialized nations. No population-based data exist on GAD as it is currently defined in DSM-5. To provide the first epidemiologic data on DSM-5 GAD and explore cross-national differences in its prevalence, course, correlates, and impact. Data come from the World Health Organization World Mental Health Survey Initiative. Cross-sectional general population surveys were carried out in 26 countries using a consistent research protocol and assessment instrument. A total of 147 261 adults from representative household samples were interviewed face-to-face in the community. The surveys were conducted between 2001 and 2012. Data analysis was performed from July 22, 2015, to December 12, 2016. The Composite International Diagnostic Interview was used to assess GAD along with comorbid disorders, role impairment, and help seeking. Respondents were 147 261 adults aged 18 to 99 years. The surveys had a weighted mean response rate of 69.5%. Across surveys, DSM-5 GAD had a combined lifetime prevalence (SE) of 3.7% (0.1%), 12-month prevalence of 1.8% (0.1%), and 30-day prevalence of 0.8% (0). Prevalence estimates varied widely across countries, with lifetime prevalence highest in high-income countries (5.0% [0.1%]), lower in middle-income countries (2.8% [0.1%]), and lowest in low-income countries (1.6% [0.1%]). Generalized anxiety disorder typically begins in adulthood and persists over time, although onset is later and clinical course is more persistent in lower-income countries. Lifetime comorbidity is high (81.9% [0.7%]), particularly with mood (63.0% [0.9%]) and other anxiety (51.7% [0.9%]) disorders. Severe role impairment is common across life domains (50.6% [1.2%]), particularly in high-income countries. Treatment is sought by approximately half of

Association between home food preparation skills and behaviour, and consumption of ultra-processed foods: Cross-sectional analysis of the UK National Diet and nutrition survey (2008-2009).

'Ultra-processed foods' (UPF) have been industrially processed and tend to be higher in saturated fat, sodium and sugar than other foods. There is some evidence that consumption of UPF is associated with overweight, obesity and related diseases. In developed countries more than half of dietary energy is attributed to UPF. One reason for reliance on UPF may be poor home food preparation skills or infrequent use of these. This relationship has been previously proposed but not tested. We examined the relationship between home food preparation skills and behaviour and consumption of UPF. We used data from adults in the UK National Diet & Nutrition Survey 2008-09. Home food preparation skills and behaviours of adults (n = 509) were assessed using questions on confidence using eight cooking techniques, confidence cooking 10 foods, ability to prepare a cake or biscuits without help, and whether or not participants prepared a main meal five or more days per week. Individuals' UPF consumption was determined from four-day estimated diet diaries. Associations were adjusted for age, gender, occupational social class and household composition. In fully adjusted models, individuals who were confident with all 10 foods (adjusted beta (95% CI) = -3.76 (-6.02 to -1.50)), able to bake cakes or biscuits without help (-3.87 (-6.62 to -1.12)), and cooked a main meal at least five days a week (-2.84 (-5.43 to -0.24)) consumed a lower percentage of dietary energy from UPF. In UK adults better home food preparation skills and more frequent use of these skills tended to be cross-sectionally associated with lower UPF consumption. Greater encouragement of these skills may help reduce reliance on UPF.

The WIMSD4 code has been adopted for cross-section generation in support of the Reduced Enrichment Research and Test Reactor (RERTR) program at Argonne National Laboratory (ANL). Subsequently, the code has undergone several updates, and significant improvements have been achieved. The capability of generating group-collapsed micro- or macroscopic cross sections from the ENDF/B-V library and the more recent evaluation, ENDF/B-VI, in the ISOTXS format makes the modified version of the WIMSD4 code, WIMSD4M, very attractive, not only for the RERTR program, but also for the reactor physics community. The intent of the present paper is to validate the WIMSD4M cross-section librariesmore » for reactor modeling of fresh water moderated cores. The results of calculations performed with multigroup cross-section data generated with the WIMSD4M code will be compared against experimental results. These results correspond to calculations carried out with thermal reactor benchmarks of the Oak Ridge National Laboratory (ORNL) unreflected HEU critical spheres, the TRX LEU critical experiments, and calculations of a modified Los Alamos HEU D{sub 2}O moderated benchmark critical system. The benchmark calculations were performed with the discrete-ordinates transport code, TWODANT, using WIMSD4M cross-section data. Transport calculations using the XSDRNPM module of the SCALE code system are also included. In addition to transport calculations, diffusion calculations with the DIF3D code were also carried out, since the DIF3D code is used in the RERTR program for reactor analysis and design.

This study was carried out to: (1) explore the views of pharmacists in Nigeria on the extension of prescribing authority to them and determine their willingness to be prescribers and (2) identify the potential facilitators and barriers to introducing pharmacist prescribing in Nigeria. An online cross-sectional survey was conducted from August to October 2014 among 775 pharmacists recruited from the Facebook group of the Pharmaceutical Society of Nigeria using a simple random technique. The questionnaire used for the survey was developed based on the review of the literature and previous qualitative studies conducted in Nigeria. The instrument was evaluated for content validity by two external pharmacy practice researchers and the reliability of items assessed using internal consistency tests. Data obtained from the survey were entered into SPSS v.22, and descriptive statistics were generated. Relationships between variables were evaluated using the chi-square test, and P < 0.05 was considered statistically significant. The response rate was 40.6% (315/775). Three hundred and six (97.1%) respondents agreed that pharmacists should be given prescribing authority. Of these 306, 295 (96.4%) were willing to be prescribers, and just over half of them (148/295; 50.2%) would prefer to prescribe in collaboration with medical doctors. Of those willing to be prescribers, 285 (96.6%) reported that they would need additional training. The most perceived areas of training needed were in the principles of differential diagnosis (81.4%), pathophysiology of diseases (74.0%) and interpretation of laboratory results (68.1%). Respondents identified increasing patients' access to care (308/315; 97.8%) and better utilisation of pharmacists' skills (307/315; 97.5%) as the most likely facilitators to pharmacist prescribing in Nigeria. On the other hand, resistance from the medical doctors (299/315; 94.9%) and pharmacists' inadequate skills in diagnosis (255/315; 81.0%) were perceived as

Accurate neutron-capture cross sections on unstable nuclei near the line of beta stability are crucial for understanding the s-process nucleosynthesis. However, neutron-capture cross sections for short-lived radionuclides are difficult to measure due to the fact that the measurements require both highly radioactive samples and intense neutron sources. Essential ingredients for describing the γ decays following neutron capture are the γ-ray strength function and level densities. We will compare different indirect approaches for obtaining the most relevant observables that can constrain Hauser-Feshbach statistical-model calculations of capture cross sections. Specifically, we will consider photon scattering using monoenergetic and 100% linearly polarized photonmore » beams. Here, challenges that exist on the path to obtaining neutron-capture cross sections for reactions on isotopes near and far from stability will be discussed.« less

Routine pelvic examinations have been a fundamental part of the annual female examination. The 2014 American College of Physicians (ACP) guideline recommends against routine pelvic examinations in asymptomatic, nonpregnant, average-risk women. Our aim was to evaluate women's attitudes and beliefs about pelvic examinations and how knowledge of the new guidelines contributes to attitudes and beliefs. A descriptive cross-sectional study was performed using a self-administered written survey developed through literature review and pretested and revised on the basis of staff suggestions. Nonpregnant women age≥21years presenting to outpatient clinics at Mayo Clinic in Arizona or Mayo Clinic in Rochester, Minnesota, received the survey. After being asked about pelvic examination practices and beliefs, participants were informed of the ACP guideline, to determine effect on attitudes and beliefs. Demographic characteristics and pertinent medical history questions were collected from participants. In total, 671 women who were predominantly white, married, and educated completed surveys. Participants described pelvic examinations as reassuring, and a majority believed the examinations were useful in detecting ovarian cancer (74.6%), necessary for screening for sexually transmitted infections (STIs) (71.0%), or necessary before initiating contraception (67.0%). After reading the 2014 ACP guideline, significantly fewer women planned to continue yearly pelvic examinations (P<0.001). Despite evidence to the contrary, women believed pelvic examinations were necessary for STI screening, contraception initiation, and ovarian cancer detection. After education on the ACP screening guideline, fewer women planned to continue yearly pelvic examinations. Copyright © 2016 Elsevier Inc. All rights reserved.

To assess the current status of leadership training as perceived by family medicine residents to inform the development of a formal leadership curriculum. Cross-sectional quantitative survey. Department of Family Medicine at McMaster University in Hamilton, Ont, in December 2013. A total of 152 first- and second-year family medicine residents. Family medicine residents' attitudes toward leadership, perceived level of training in various leadership domains, and identified opportunities for leadership training. Overall, 80% (152 of 190) of residents completed the survey. On a Likert scale (1 = strongly disagree, 4 = neutral, 7 = strongly agree), residents rated the importance of physician leadership in the clinical setting as high (6.23 of 7), whereas agreement with the statement "I am a leader" received the lowest rating (5.28 of 7). At least 50% of residents desired more training in the leadership domains of personal mastery, mentorship and coaching, conflict resolution, teaching, effective teamwork, administration, ideals of a healthy workplace, coalitions, and system transformation. At least 50% of residents identified behavioural sciences seminars, a lecture and workshop series, and a retreat as opportunities to expand leadership training. The concept of family physicians as leaders resonated highly with residents. Residents desired more personal and system-level leadership training. They also identified ways that leadership training could be expanded in the current curriculum and developed in other areas. The information gained from this survey might facilitate leadership development among residents through application of its results in a formal leadership curriculum.

Objectives Since sex hormone markers are metabolically linked, examining sex steroid hormones singly may account for inconsistent findings by age, race/ethnicity and body mass index (BMI) across studies. First, these markers were statistically combined into profiles to account for the metabolic relationship between markers. Then, the relationships between sex steroid hormone profiles and age, race/ethnicity and BMI were explored in multinomial logistic regression models. Design Cross-sectional survey. Setting The US Third National Health and Nutrition Examination Survey (NHANES III). Participants 1538 Men, >17 years. Primary outcome measure Sex hormone profiles. Results Cluster analysis was used to identify four statistically determined profiles with Blom-transformed T, E, sex hormone binding globulin (SHBG), and 3-α diol G. We used these four profiles with multinomial logistic regression models to examine differences by race/ethnicity, age and BMI. Mexican American men >50 years were associated with the profile that had lowest T, E and 3-α diol G levels compared to other profiles (p<0.05). Non-Hispanic Black, overweight (25–29.9 kg/m2) and obese (>30 kg/m2) men were most likely to be associated with the cluster with the lowest SHBG (p<0.05). Conclusion The associations of sex steroid hormone profiles by race/ethnicity are novel, while the findings by age and BMI groups are largely consistent with observations from single hormone studies. Future studies should validate these hormone profile groups and investigate these profiles in relation to chronic diseases and certain cancers. PMID:23043125

Measures of maternal mortality and severe maternal morbidity have risen in the United States, sparking national interest regarding hospitals' ability to provide maternal risk-appropriate care. We examined the extent to which hospitals could be classified by increasingly sophisticated maternal levels of care. We performed a cross-sectional survey to identify hospital-specific resources and classify hospitals by criteria for basic, intermediate, and regional maternal levels of care in all nonmilitary childbirth hospitals in California. We measured hospital compliance with maternal level of care criteria that were produced via consensus based on professional standards at 2 regional summits funded by the March of Dimes through a cooperative agreement with the Community Perinatal Network in 2007 (California Perinatal Summit on Risk-Appropriate Care). The response rate was 96% (239 of 248 hospitals). Only 82 hospitals (34%) were classifiable under these criteria (35 basic, 42 intermediate, and 5 regional) because most (157 [66%]) did not meet the required set of basic criteria. The unmet criteria preventing assignment into the basic category included the ability to perform a cesarean delivery within 30 minutes 100% of the time (only 64% met), pediatrician availability day and night (only 56% met), and radiology department ultrasound capability within 12 hours (only 83% met). Only 29 of classified hospitals (35%) had a nursery or neonatal intensive care unit level that matched the maternal level of care, and for most remaining hospitals (52 of 53), the neonatal intensive care unit level was higher than the maternal care level. Childbirth services varied widely across California hospitals, and most hospitals did not fit easily into proposed levels. Cognizance of this existing variation is critical to determining the optimal configuration of services for basic, intermediate, and regional maternal levels of care. Copyright © 2015 Elsevier Inc.

Background Antiretroviral (ARV) drug treatment benefits the treated individual and can prevent HIV transmission. We assessed ARV drug use in a community-randomized trial that evaluated the impact of behavioral interventions on HIV incidence. Methods Samples were collected in a cross-sectional survey after a 3-year intervention period. ARV drug testing was performed using samples from HIV-infected adults at four study sites (Zimbabwe; Tanzania; KwaZulu-Natal and Soweto, South Africa; survey period 2009–2011), using an assay that detects 20 ARV drugs (6 nucleoside/nucleotide reverse transcriptase inhibitors [NRTIs]; 3 non-nucleoside reverse transcriptase inhibitors [NNRTIs]; 9 protease inhibitors; maraviroc; raltegravir). Results ARV drugs were detected in 2,011 (27.4%) of 7,347 samples; 88.1% had 1 NNRTI +/− 1–2 NRTIs. ARV drug detection was associated with sex (women>men), pregnancy, older age (>24 years), and study site (p<0.0001 for all four variables). ARV drugs were also more frequently detected in adults who were widowed (p=0.006) or unemployed (p=0.02). ARV drug use was more frequent in intervention versus control communities early in the survey (p=0.01), with a significant increase in control (p=0.004) but not in intervention communities during the survey period. In KwaZulu-Natal, a 1% increase in ARV drug use was associated with a 0.14% absolute decrease in HIV incidence (p=0.018). Conclusions This study used an objective, biomedical approach to assess ARV drug use on a population level. This analysis identified factors associated with ARV drug use and provided information on ARV drug use over time. ARV drug use was associated with lower HIV incidence at one study site.

Objective This study surveyed all Iraqi medical schools and a cross-section of Iraqi medical students regarding their institutional and student experiences of medical education amidst ongoing conflict. The objective was to better understand the current resources and challenges facing medical schools, and the impacts of conflict on the training landscape and student experience, to provide evidence for further research and policy development. Setting Deans of all Iraqi medical schools registered in the World Directory of Medical Schools were invited to participate in a survey electronically. Medical students from three Iraqi medical schools were invited to participate in a survey electronically. Outcomes Primary: Student enrolment and graduation statistics; human resources of medical schools; dean perspectives on impact of conflict. Secondary: Medical student perspectives on quality of teaching, welfare and future career intentions. Findings Of 24 medical schools listed in the World Directory of Medical Schools, 15 replied to an initial email sent to confirm their contact details, and 8 medical schools responded to our survey, giving a response rate from contactable medical schools of 53% and overall of 33%. Five (63%) medical schools reported medical student educational attainment being impaired or significantly impaired; 4 (50%) felt the quality of training medical schools could offer had been impaired or significantly impaired due to conflict. A total of 197 medical students responded, 62% of whom felt their safety had been threatened due to violent insecurity. The majority (56%) of medical students intended to leave Iraq after graduating. Conclusions Medical schools are facing challenges in staff recruitment and adequate resource provision; the majority believe quality of training has suffered as a result. Medical students are experiencing added psychological stress and lower quality of teaching; the majority intend to leave Iraq after graduation. PMID:26883241

Psychiatric illnesses have recently escalated in numbers, with patients resorting to various forms of healthcare providers, including faith healers. This delays early psychiatric treatment, resulting in further mental health deterioration of the patient. Various factors impact the mode of treatment preferred by psychiatric patients. To determine the frequency of psychiatric patients visiting faith healers, presenting at the outpatient department of Liaquat National Hospital, Karachi, Pakistan, and to explore the predictors that direct them toward visiting faith healers. This cross-sectional survey was conducted using a semi-structured pre-tested questionnaire, employing a total of 219 male and female psychiatric patients. Patients were recruited through non-random consecutive sampling technique. SPSS 18 was used for statistical analysis. About 32% of the patients had visited a faith healer in their lifetime. Frequency of current visitors declined; the most frequent reason being stated was no relief from their treatment. Students, patients of upper middle class and those coming for initial visit to a psychiatrist were more likely to visit a faith healer. Patients who knew of someone previously visiting a faith healer were less likely to have visited a faith healer. This study highlights the importance of a multisectoral approach to dealing with psychiatric patients to help in bridging the treatment gap in mental health.

Despite careful selection processes, residency programs face the challenge of training residents who fall below minimal performance standards. Poor performance of a resident can endanger both patient safety and the reputation of the residency program. It is important, therefore, for a program to identify such residents and implement strategies for their successful remediation. The purpose of our study was to gather information on evaluation and remediation strategies employed by different otolaryngology programs. Cross-sectional survey. We conducted a national survey, sending a questionnaire to the program directors of 106 otolaryngology residency programs. We collected information on demographics of the program, identification of problematic residents, and remediation strategies. The response rate was 74.5%, with a 2% cumulative incidence of problematic residents in otolaryngology programs during the past 10 years. The most frequently reported deficiencies of problematic residents were unprofessional behavior with colleagues/staff (38%), insufficient medical knowledge (37%), and poor clinical judgment (34%). Personal or professional stress was the most frequently identified underlying problem (70.5%). Remediation efforts included general counseling (78%), frequent feedback sessions (73%), assignment of a mentor (58%), and extra didactics (47%). These remediation efforts failed to produce improvement in 23% of the identified residents, ultimately leading to their dismissal. The apparent deficiencies, underlying causes, and remediation strategies vary among otolaryngology residency programs. Based on the results of this survey, we offer recommendations for the early identification of problematic residents and a standardized remediation plan.

Sleep disturbances are common during pregnancy, yet few studies are currently available regarding the determinants of sleep quality among pregnant women in China. This study aimed to: (a) calculate the prevalence of sleep disorder during pregnancy, (b) examine the difference in sleep quality among three trimesters, and (c) identify determinants of sleep quality in pregnant women. This study was designed as a cross-sectional survey. Five hundred pregnant women were recruited at the outpatient department of obstetrics and gynecology of two teaching hospitals in central China. Five selfreport questionnaires were used for gathering data, including information of sample characteristics, sleep quality (Pittsburgh Sleep Quality Index (PSQI)), prenatal depression (the Edinburgh Postnatal Depression Scale (EPDS)), perceived stress (Perceived Stress Scale (PSS)), and perceived social support (Multidimensional Scale of Perceived Social Support (MSPSS)). A total of 454 pregnant women participated in the study between September 2016 and April 2017. Eighty-seven percent pregnant women experienced sleep disorder (PSQI score >5). Poorer global sleep quality, subjective sleep quality, lower sleep efficiency and sleep disturbances were most prevalent during third trimester. The significant contributors to sleep quality for pregnant women were prenatal depression, maternal age, and gestational age. Sleep disorder is very common in pregnant women from China. Depressive symptoms, increased maternal age, and gestational age are determinants of sleep quality. These determinants can assist healthcare professionals in preventative intervention.

Clinical Governance (CG) program has been raised in Iran in order to improve the quality of clinical care. The purpose of this study is to investigate the awareness of clinical governance program among clinical staff working in selected teaching hospitals in Tehran, Iran. To investigate the CG awareness, a cross-sectional survey was conducted among 345 clinical staff working in 20 selected public hospitals in Tehran. Data were gathered using the standardized clinical governance awareness questionnaire. Descriptive statistics were used to analyze the data. The results showed that the level of staff awareness about the concept of CG was low. They perceived continuous quality improvement, responsibility, medical errors reduction and patient safety as the main concepts of the CG framework. Reaching agreement of standards concepts among staff and positive changes in attitudes were considered as two most observed changes. The main perceived barriers to the implementation of clinical governance included lack of proper management and leadership, lack of full support, inappropriate organizational culture, lack of knowledge, poor communication system and insufficient training. The concepts and goals of clinical governance have not been effectively conveyed to the staff and despite its implementation in the hospitals, there has been low clinical governance awareness among the staff. Clinical Governance must be implemented through comprehensive management support and participation of all staff and health professionals at both hospital and policy making level.

Although only a few studies have been published on teachers' health, certain ideas are widely accepted, such as for example, the preconceived notion that teachers suffer from an excessively high rate of mental health problems. The objective of this study is to compare teachers' mental and physical health to that of a control group. A cross-sectional postal survey was conducted among a sample of 3,679 teachers and 1,817 non-teachers aged 20 to 60 years old. No lifetime prevalence of any psychiatric disorder (with the exception of undifferentiated somatoform disorder in men) or mean scores of psychological distress were found to be significantly higher in teachers. However, multiple analyses, adjusted for all confounding variables, revealed a higher risk of lifetime anxiety disorders in male teachers. On the other hand, significant differences were observed for some physical ailments: a higher lifetime prevalence of rhinopharyngitis/laryngitis in both male and female teachers, of conjunctivitis and lower urinary tract infection in male teachers and of bronchitis, eczema/dermatitis and varicose veins in female teachers. No significant difference was found for chronic pain between the two groups. Teachers do not seem to have poorer mental health. However, their physical condition is characterized by a higher prevalence of health problems related to the ENT tract, and to a lesser extent, depending on the gender, to skin, eyes, legs and lower urinary tract.

Design Cross-sectional survey. Setting The Fifth National Health Service Survey was carried out in Guangdong, China. Participants All participants in this study were healthcare staff including physicians, nurses and public health staff from hospitals, health service centres and health clinics. A total of 6583 questionnaires were distributed and collected. After excluding the incomplete questionnaires, 5845 questionnaires were included for the analysis. Outcome measures Sociodemographic information and scores for evaluating job satisfaction, work stress, work–family conflict and doctor–patient relationship were obtained using the questionnaire developed by the National Health and Family Planning Commission of the People's Republic of China. To assess the significantly associated factors on job satisfaction of the healthcare staff in Guangdong, a binary logistic regression model was used. Results Based on the 5845 valid responses of the healthcare staff who worked in Guangdong, the mean score of overall perception of job satisfaction was 3.99 on a scale of 1–6. Among the sociodemographic variables, occupation, educational background, professional status, years of service, annual income and night shift frequency significantly influenced the level of job satisfaction. Work stress, work–family conflict and doctor–patient relationship also had significant effect on job satisfaction. Conclusions The overall job satisfaction exceeded slightly dissatisfied (score 3) and approached slightly satisfied (score 4). Measures to enhance job satisfaction include the reduction of workload, increase of welfare, maintaining moderate stress and balancing work–family conflict. Moreover

Previous work demonstrates that many surgery residents underreport duty hours. The purpose of this study was to identify characteristics of these residents and better understand why they exceed duty hours. During the winter of 2015 we conducted an anonymous cross-sectional survey of Accreditation Council for Graduate Medical Education accredited general surgery programs. A total of 101 general surgery residency programs across the United States. A total of 1003 general surgery residents across the United States. Respondents' mean age was 29.9 ± 3.0 years; 53% were male. Study response rate was 31.9%. Residents age <30 were more likely to exceed duty hours to complete charting/documentation (68% vs. 54%, p < 0.001). Females more often cited guilt about leaving the hospital (32% vs. 24%, p = 0.014) as to why they exceed duty hours. Programs with >40 residents had the highest rates of underreporting (82% vs. 67% in other groups p < 0.001) and residents who worked >90 hours on an average week more frequently cited external pressure (p = 0.0001), guilt (p = 0.006), and feeling it was expected of them (p < 0.0001) as reasons why they underreport compared to those who worked fewer hours. Underreporting and duty-hour violations are a complex issue influenced by many variables including age, sex, and internal and external pressures.

Neutron cross section standards and instrumentation. Annual report

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

Wasson, O.A.

The objective of this interagency program is to provide accurate neutron interaction measurements for the US Department of Energy nuclear programs which include waste disposal, fusion, safeguards, defense, fission, and personnel protection. These measurements are also useful to other energy programs which indirectly use the unique properties of the neutron for diagnostic and analytical purposes. The work includes the measurement of reference cross sections and related neutron data employing unique facilities and capabilities at NIST and other laboratories as required; leadership and participation in international intercomparisons and collaborations; the preservation of standard reference deposits and the development of improved neutronmore » detectors and measurement methods. A related and essential element of the program is critical evaluation of neutron interaction data including international coordinations. Data testing of critical data for important applications is included. The program is jointly supported by the Department of Energy and the National Institute of Standards and Technology. This report from the National Institute of Standards and Technology contains a summary of the accomplishments of the Neutron Cross Section Standards and Instrumentation Project during the third year of this three-year interagency agreement. The proposed program and required budget for the following three years are also presented. The program continues the shifts in priority instituted in order to broaden the program base.« less

Evaluation of proton cross-sections for radiation sources in the proton accelerator

Proton Engineering Frontier Project (PEFP) is currently building a proton accelerator in Korea which consists of a proton linear accelerator with 100 MeV of energy, 20 mA of current and various particle beam facilities. The final goal of this project consists of the production of 1 GeV proton beams, which will be used for various medical and industrial applications as well as for research in basic and applied sciences. Carbon and copper in the proton accelerator for PEPP, through activation, become radionuclides such as 7Be and 64Cu. Copper is a major element of the accelerator components and the carbon is planned to be used as a target material of the beam dump. A recent survey showed that the currently available cross-sections create a large difference from the experimental data in the production of some residual nuclides by the proton-induced reactions for carbon and copper. To more accurately estimate the production of radioactive nuclides in the accelerator, proton cross-sections for carbon and copper are evaluated. The TALYS code was used for the evaluation of the cross-sections for the proton-induced reactions. To obtain the cross-sections which best fits the experimental data, optical model parameters for the neutron, proton and other complex particles such as the deuteron and alpha were successively adjusted. The evaluated cross-sections in this study are compared with the measurements and other evaluations .

The numerical capture cross section is calculated from the capture ratio, defined as the fraction of trajectories reaching a prescribed minimum separation of 3 A. The calculated capture cross sections for a rotational temperature of 77 K suggest large reaction cross sections in 80 K experiments for the large dipole-moment target, methyl cyanide.

Objective To compare the health outcomes in sheltered and evacuated populations after a chemical incident in a plastics factory. Design Cross sectional survey. Setting Urban area in southwest England. Participants 1750 residents from the area exposed to the chemical smoke, of which 472 were evacuated and the remaining 1278 were advised to shelter indoors. Main outcome measure Number of adverse health symptoms. A case was defined by the presence of four or more symptoms. Main results 1096 residents (63%; 299 evacuated, 797 sheltered) provided data for analyses. The mean symptom score and proportion of cases were higher in evacuated people than in the sheltered population (evacuated: symptom score 1.9, cases 19.7% (n = 59); sheltered: symptom score 1.0, cases 9.5% (n = 76); P < 0.001 for both). The difference between the two groups attenuated markedly at the end of two weeks from the start of the incident. The two main modifiable risk factors for the odds of becoming a case were evacuation (odds ratio 2.5, 95% confidence interval 1.7 to 3.8) and direct exposure to smoke for more than two hours on the first day of the incident (2.0, 1.7 to 2.3). The distance of residence from the factory or level of exposure before intervention (first six hours) had little effect on the odds of a person becoming a case. Conclusions Sheltering may have been a better protective action than evacuation in this chemical incident, which is consistent with the prevailing expert view. Although this study has limitations, it is based on a real event. Evacuations carry their own risks and resource implications; increased awareness may help to reduce unnecessary evacuations in the future. PMID:15976419

Early childhood development (ECD) strongly influences children's basic learning, school success, economic participation, social citizenry and health. Although some risk factors related to childhood development are documented, further exploration is necessary considering various sociodemographic, nutritional, and psychosocial factors. This study investigated factors affecting ECD in Vietnamese preschoolers. We used data from the representative, cross-sectional round of the Vietnam Multiple Indicator Clusters Survey 2011. Early Childhood Development Index questionnaires were administered to mothers of all children aged 36-59 months in the household (n = 1459). Descriptive statistics and multivariate logistic regression were used in the analysis. In Vietnam, 17.2% of children did not reach their full developmental potential within the first 5 years. Children who had been breast-fed (AOR, 2.78; 95%CI: 1.28-6.02), attended preschool (AOR, 1.75; 95%CI: 1.28-2.39), were of major ethnicity (AOR, 2.41; 95%CI: 1.55-3.74), had a mother with secondary or higher education (AOR, 1.69; 95%CI: 1.19-2.38) and had relatives who engaged with them in four or more activities that promote learning (AOR, 1.55; 95%CI: 1.13-2.14) were more likely to have a normal developmental trajectory. Furthermore, children who experienced physical punishment and stunting were 0.69-fold (95%CI: 0.51-0.95) and 0.71-fold (95%CI: 0.51-0.98) less likely to be on track for ECD, respectively. The risk factors associated with delayed ECD were low level of maternal education; family ethnicity; lack of preschool attendance; relatives who did not engage with them in learning; physical punishment; not being breast-fed; and stunting. © 2015 Japan Pediatric Society.

Poor adherence to antipsychotic treatment is a widespread problem within schizophrenia therapy with serious consequences including increased risks of relapse and rehospitalization. Mounting evidence supports the key roles that nurses play in monitoring patient progress and facilitating long-term treatment adherence. The Adherencia Terapéutica en la Esquizofrenia (ADHES) nurses' survey was designed to assess the opinions of nurses on the causes and management of partial/nonadherence to antipsychotic medication. A questionnaire-based cross-sectional survey of 4120 nurses from Europe, the Middle East and Africa. Interpretation of results was based on a descriptive comparison of responses. Nurses perceived 54% of patients seen in the preceding month to be partially/nonadherent to treatment. Most nurses (90%) reported some level of experience with administration of long-acting injectable (LAI) antipsychotics, with 24% of nurses administering >10 injections per month. The majority (85%) of nurses surveyed believed that improving adherence would improve patient outcomes. Nearly half (49%) reported that most of their patients depend on a family member or other nonprofessional carer to remind them to take their medication as prescribed. A similar proportion of nurses (43%) reported that most of their patients relied on a professional to remind them to take medication. Most nurses (92%) felt that ensuring continuous medication with LAI antipsychotics would yield long-term benefits for patients, but their opinion was that over a third of patients were unaware of LAI antipsychotic treatments. In a series of forced options, the strategy used most often by respondents (89%) to promote medication adherence was to build trusting relationships with patients while listening to and interpreting their needs and concerns. Respondents also rated this as the most effective strategy that they used (48%). Nurses are highly aware of adherence issues faced by their patients; further patient

The development and implementation of electronic health records (EHRs) remains an international challenge. Better understanding of patient and public attitudes and the factors that influence overall levels of support toward EHRs is needed to inform policy. To explore patient and public attitudes toward integrated EHRs used simultaneously for health care provision, planning and policy, and health research. Cross-sectional questionnaire survey administered to patients and members of the public who were recruited from a stratified cluster random sample of 8 outpatient clinics of a major teaching hospital and 8 general practices in London (United Kingdom). 5331 patients and members of the public responded to the survey, with 2857 providing complete data for the analysis presented here. There were moderately high levels of support for integrated EHRs used simultaneously for health care provision, planning and policy, and health research (1785/2857, 62.47%), while 27.93% (798/2857) of participants reported being undecided about whether or not they would support EHR use. There were higher levels of support for specific uses of EHRs. Most participants were in favor of EHRs for personal health care provision (2563/2857, 89.71%), with 66.75% (1907/2857) stating that they would prefer their complete, rather than limited, medical history to be included. Of those "undecided" about integrated EHRs, 87.2% (696/798) were nevertheless in favor of sharing their full (373/798, 46.7%) or limited (323/798, 40.5%) records for health provision purposes. There were similar high levels of support for use of EHRs in health services policy and planning (2274/2857, 79.59%) and research (2325/2857, 81.38%), although 59.75% (1707/2857) and 67.10% (1917/2857) of respondents respectively would prefer their personal identifiers to be removed. Multivariable analysis showed levels of overall support for EHRs decreasing with age. Respondents self-identifying as Black British were more likely to

Influenza immunization among Canadian health care personnel: a cross-sectional study

Background: Influenza immunization coverage among Canadian health care personnel remains below national targets. Targeting this group is of particular importance given their elevated risk of influenza infection, role in transmission and influence on patients' immunization status. We examined influenza immunization coverage in health care personnel in Canada, reasons for not being immunized and the impact of "vaccinate-or-mask" influenza prevention policies. Methods: In this national cross-sectional study, we pooled data from the 2007 to 2014 cycles of the Canadian Community Health Survey and restricted it to respondents who reported a health care occupation. Using bootstrapped survey weights, we examined immunization coverage by occupation and by presence of vaccinate-or-mask policies, and reasons for not being immunized. We used modified Poisson regression to estimate the prevalence ratio (PR) of influenza immunization for health care occupations compared with the general working population. Results: For all survey cycles combined, 50% of 18 446 health care personnel reported receiving seasonal influenza immunization during the previous 12 months, although this varied by occupation type (range 4%-72%). Compared with the general working population, family physicians and general practitioners were most likely to be immunized (PR 3.15, 95% confidence interval [CI] 2.76-3.59), whereas chiropractors, midwives and practitioners of natural healing were least likely (PR 0.17, 95% CI 0.10-0.30). Among those who were not immunized, the most frequently cited reason was the belief that influenza immunization is unnecessary. Introduction of vaccinate-or-mask policies was associated with increased influenza immunization among health care personnel. Interpretation: Health care personnel are more likely to be immunized against influenza than the general working population, but coverage remains suboptimal overall, and we observed wide variation by occupation type.

This work presents some data of relevance from the National Survey on Working Conditions, carried out in Spain in 1993. A cross-section survey was undertaken on a representative sample of the industry and services sectors (3,148 workers), both through an individual interview which took place at their places of work, and a questionnaire. The study revealed that preventive activities are few and far between. Only 11.8% of the companies carried out surveys into the risk of occupational accidents and/or illnesses. This datum contrasts with the high incidence among workers of exposure to the risk of accidents (59%), noise (33%) or the inhaling of chemical substances (32%). Furthermore, approximately 50% of workers spend at least a quarter of their work time in a static posture or making repetitive hand-arm movements. It is estimated that 60% are exposed to high work rates or repetitive tasks of short duration. Where the question of morbidity is concerned, 60% of workers suffer from posture problems associated with their work. In this study, a comparison is made between these findings per activity sector, together with a detailed analysis of morbidity. Finally, it should be borne in mind, that the subjectivity in the responses and answers, which is inherent to any qualitative survey, should not be regarded as a negative aspect. The way in which the worker perceives and experiences his or her work environment, provides essential information for the preventionists.

Objective This paper presents an overview of the background and measures used in the National Comorbidity Survey Replication Adolescent Supplement (NCS-A). Methods The NCS-A is a national psychiatric epidemiological survey of adolescents ages 13–17. Results The NCS-A was designed to provide the first nationally representative estimates of the prevalence, correlates and patterns of service use for DSM-V mental disorders among US adolescents and to lay the groundwork for follow-up studies of risk-protective factors, consequences, and early expressions of adult mental disorders. The core NCS-A diagnostic interview, the World Health Organization (WHO) Composite International Diagnostic Interview (CIDI), is a fully-structured research diagnostic interview designed for use by trained lay interviewers. A multi-construct, multi-method, multi-informant battery was also included to assess risk and protective factors and barriers to service use. Design limitations due to the NCS-A evolving as a supplement to an ongoing survey of mental disorders of US adults include restricted age range of youth, cross-sectional assessment, and lack of full parental/surrogate informant reports on youth mental disorders and correlates. Conclusions Despite these limitations, the NCS-A contains unparalleled information that can be used to generate national estimates of prevalence and correlates of adolescent mental disorders, risk and protective factors, patterns of service use, and barriers to receiving treatment for these disorders. The retrospective NCS-A data on the development of psychopathology can additionally complement data from longitudinal studies based on more geographically restricted samples and serve as a useful baseline for future prospective studies of the onset and progression of mental disorders in adulthood.

Clinical leadership and organizational culture are important contextual factors for quality improvement (QI) but the relationship between these and with organizational change is complex and poorly understood. We aimed to explore the relationship between clinical leadership, culture of innovation and clinical engagement in QI within a national ambulance QI Collaborative (QIC). We used a self-administered online questionnaire survey sent to front-line clinicians in all 12 English ambulance services. We conducted a cross-sectional analysis of quantitative data and qualitative analysis of free-text responses. There were 2743 (12% of 22 117) responses from 11 of the 12 participating ambulance services. In the 3% of responders that were directly involved with the QIC, leadership behaviour was significantly higher than for those not directly involved. QIC involvement made no significant difference to responders' perceptions of the culture of innovation in their organization, which was generally considered poor. Although uptake of QI methods was low overall, QIC members were significantly more likely to use QI methods, which were also significantly associated with leadership behaviour. Despite a limited organizational culture of innovation, clinical leadership and use of QI methods in ambulance services generally, the QIC achieved its aims to significantly improve pre-hospital care for acute myocardial infarction and stroke. We postulate that this was mediated through an improvement subculture, linked to the QIC, which facilitated large-scale improvement by stimulating leadership and QI methods. Further research is needed to understand success factors for QI in complex health care environments. © 2016 The Authors.

We aimed to determine the prevalence of violence directed at emergency department (ED) physicians in Turkey and confirm the factors influencing such violence. Cross-sectional survey study. Country of Turkey. Physicians currently practising in EDs in Turkey. The prevalence of violence directed at physicians and factors that may influence it, such as physicians' personal characteristics, ED characteristics and physicians' opinions regarding the causes of and suggested methods of preventing violence. A total of 713 physicians participated. Of these, 78.1% reported being subjected to violence in the past year and 65.9% reported more than one such incident. Being subjected to violence was related to age (p=0.008), working in an ED with a high patient admission rate (p=0.018), current position (p<0.001), working outside regular work hours (p<0.001), working in a state hospital (p<0.001) and level of experience (p<0.001). Gender, type of patient typically seen, region and patient waiting period did not influence subjection to violence. The present safety precautions against violence do not appear to influence the prevalence of violence. Our results indicated that ED physicians' experience of violence is related to personal characteristics such as age and level of expertise, and hospital and ED characteristics such as high patient admission rates. Presently, no measures taken to reduce this violence have been proven effective. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

To assess the responses of physicians to providing emergency medical assistance outside of routine clinical care. We assessed the percentage who reported previous Good Samaritan behaviour, their responses to hypothetical situations, their comfort providing specific interventions and the most likely reason they would not intervene. Physicians residing in North Carolina. Convenience sample of 1000 licensed physicians. Mailed survey. Cross-sectional study conducted May 2015 to September 2015. Willingness of physicians to act as Good Samaritans as determined by the last opportunity to intervene in an out-of-office emergency. The adjusted response rate was 26.1% (253/970 delivered). 4 out of 5 physicians reported previous opportunities to act as Good Samaritans. Approximately, 93% reported acting as a Good Samaritan during their last opportunity. There were no differences in this outcome between sexes, practice setting, specialty type or experience level. Doctors with greater perceived knowledge of Good Samaritan law were more likely to have intervened during a recent opportunity (p=0.02). The most commonly cited reason for potentially not intervening was that another health provider had taken charge. We found the frequency of Good Samaritan behaviour among physicians to be much higher than reported in previous studies. Greater helping behaviour was exhibited by those who expressed more familiarity with Good Samaritan law. These findings suggest that physicians may respond to legal protections.

In support of the reaction microscope measurements at the free-electron laser facility at Hamburg (FLASH), we use the time-dependent close-coupling method (TDCC) to calculate fully differential nuclear-recoil cross sections for the two-photon double ionization of He at photon energy of 44 eV. The total cross section for the double ionization is in good agreement with previous calculations. The nuclear-recoil distribution is in good agreement with the experimental measurements. In contrast to the single-photon double ionization, maximum nuclear recoil triple differential cross section is obtained at small nuclear momenta.

Accurate Cross Sections for Microanalysis.

PubMed

Rez, Peter

2002-01-01

To calculate the intensity of x-ray emission in electron beam microanalysis requires a knowledge of the energy distribution of the electrons in the solid, the energy variation of the ionization cross section of the relevant subshell, the fraction of ionizations events producing x rays of interest and the absorption coefficient of the x rays on the path to the detector. The theoretical predictions and experimental data available for ionization cross sections are limited mainly to K shells of a few elements. Results of systematic plane wave Born approximation calculations with exchange for K, L, and M shell ionization cross sections over the range of electron energies used in microanalysis are presented. Comparisons are made with experimental measurement for selected K shells and it is shown that the plane wave theory is not appropriate for overvoltages less than 2.5 V.

Our primary aim was to determine the rate of overseas travel in immunocompromised individuals attending appropriate clinics at an Australian tertiary care hospital. We also aimed to characterise health-seeking behaviour prior to travel and investigated sources of pre-travel advice, compared travel patterns and activities between three specific immunosuppressed groups, and examined pre-immunosuppression patient serology. We implemented a cross-sectional survey of patients between February and August 2012. This survey was implemented among three outpatient populations at Monash Medical Centre, an Australian tertiary care hospital. We recruited 254 immunosuppressed adults from three patient populations: human immunodeficiency virus-positive individuals, renal transplant patients and rheumatology patients requiring immunosuppressive therapy. No clinical intervention was performed. In the 10 years preceding the survey, 153 (60.2%) participants reported international travel. Of these, 105 (68.6%) were immunosuppressed at the time of travel. These patients were 47.6% male and 60% Australian born. Forty per cent were visiting friends and relatives as part of their travel. Fifty-four per cent of those immunocompromised at the time of travel were going to high-risk destinations. Pathology files indicated that serological screening was frequently not performed prior to immunosuppression in the renal transplant and rheumatology groups. Immunocompromised patients often travel to high-risk destinations with limited or inadequate pre-travel preparations. Doctors caring for the immunocompromised should be aware of travel risks, suitable vaccination protocols and when to refer to specialist travel clinics. © 2015 Royal Australasian College of Physicians.

To explore trends, and identify risk factors, that may explain changes in adolescent exposure to family violence over time. Data for this study was drawn from the Youth 2000 series of cross-sectional surveys, carried out with New Zealand high school students in 2001, 2007 and 2012. Latent class analysis was used to understand different patterns of exposure to multiple risks for witnessing violence at home among adolescents. Across all time periods, there was no change in witnessing emotional violence and a slight decline in witnessing physical violence at home. However, significant differences were noted between 2001 and 2007, and 2007 and 2012, in the proportion of adolescents who reported witnessing emotional and physical violence. Four latent classes were identified in the study sample; these were characterised by respondents' ethnicity, concerns about family relationships, food security and alcohol consumption. For two groups (characterised by food security, positive relationships and lower exposure to physical violence), there was a reduction in the proportion of respondents who witnessed physical violence but an increase in the proportion who witnessed emotional violence between 2001 and 2012. For the two groups characterised by poorer food security and higher exposure to physical violence, there were no changes in witnessing of physical violence in the home. Implications for public health: In addition to strategies directly aimed at violence, policies are needed to address key predictors of violence exposure such as social disparities, financial stress and alcohol use. These social determinants of health cannot be ignored. © 2018 The Authors.

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