Thresholds and the rising pion inclusive cross section

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

Jones, S.T.

In the context of the hypothesis of the Pomeron-f identity, it is shown that the rising pion inclusive cross section can be explained over a wide range of energies as a series of threshold effects. Low-mass thresholds are seen to be important. In order to understand the contributions of high-mass thresholds (flavoring), a simple two-channel multiperipheral model is examined. The analysis sheds light on the relation between thresholds and Mueller-Regge couplings. In particular, it is seen that inclusive-, and total-cross-section threshold mechanisms may differ. A quantitative model based on this idea and utilizing previous total-cross-section fits is seen to agreemore » well with experiment.« less

GP registrar well-being: a cross-sectional survey

2010-01-01

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

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

Retention of indigenous nursing students in New Zealand: a cross-sectional survey.

2011-01-01

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.

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

The study investigated whether perceived social support varied among children who have lost their parents to AIDS, those who have lost their parents to other causes, those who are living with HIV/AIDS-infected caregivers and children from intact families (comparison group). This study employed cross-sectional, quantitative survey that involved 291 children aged 10-18 years in the Lower Manya Krobo District of Ghana and examined their social support disparities. Multivariate linear regressions indicate that children living with HIV/AIDS-infected caregivers reported significantly lower levels of social support compared with AIDS-orphaned children, other-orphaned children and non-orphaned children independent of socio-demographic covariates. Children who have lost their parents to other causes and other-orphaned children reported similar levels of social support. In terms of sources of support, all children orphans and vulnerable children were more likely to draw support from friends and significant others rather than from the family. The findings indicate a need to develop interventions that can increase levels of social support for orphaned and vulnerable children within the context of HIV/AIDS in Ghana, particularly networks that include the family.

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.

Throughout the world, there is increasing awareness and acknowledgement of the value of research evidence in the development of effective health policy and in quality health care practice and administration. Among the major challenges associated with the lack of uptake of research evidence into policy and practice in Nigeria is the capacity constraints of policymakers to use research evidence in policy making. To assess the capacity of maternal and child health policy makers to acquire, access, adapt and apply available research evidence. This cross-sectional quantitative survey was conducted at a national maternal, newborn and child health (MNCH) stakeholders' engagement event. An evidence to policy self-assessment questionnaire was used to assess the capacity of forty MNCH policy makers to acquire, assess, adapt and apply research evidence for policy making. Low mean ratings were observed ranging from 2.68-3.53 on a scale of 5 for knowledge about initiating/conducting research and capacity to assess authenticity, validity, reliability, relevance and applicability of research evidence and for organizational capacity for promoting and using of research for policy making. There is need to institute policy makers' capacity development programmes to improve evidence-informed policymaking.

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.

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.

2017-01-01

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.

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.

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

Bade, Kim; Hoogerbrug, Jonathan

2015-01-01

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.

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.

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.

Prior research has often overlooked potential cohort differences in marijuana views and use across adolescence and young adulthood. To begin to address this gap, we conduct an exploratory examination of marijuana views and use among American youth using a panel of cross-sectional surveys. Findings are based on repeated, cross-sectional data collected annually from adolescents (ages 12-17; n=230,452) and young adults (ages 18-21; n=120,588) surveyed as part of the National Survey on Drug Use and Health between 2002 and 2014. For each of the birth years between 1986 and 1996, we combined a series of nationally representative cross-sections to provide multi-year data strings designed to approximate nationally representative cohorts. Compared to youth born in the mid-to-late 1980s, youth born in the mid-1990s reported significantly higher levels of marijuana disapproval during the early adolescent years (Age 14: 1988=64.7%, 1994=70.4%) but lower levels of disapproval during the young adult years (Age 19: 1988=32.0%, 1994=25.0%; Age 20: 1988=27.9%, 1994=19.7%). Moreover, the prevalence of marijuana use among youth born in 1994 was significantly lower-compared to youth born in 1988-at age 14 (1988: 11.39%, 1994: 8.19%) and significantly higher at age 18 (1988: 29.67%, 1994: 34.83%). This pattern held even when adjusting for potential confounding by demographic changes in the population across the study period. We see evidence of changes in the perceptions of marijuana use among youth born during the late twentieth century. Copyright © 2016 Elsevier Ireland 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.

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

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.

Occupational risks for voice disorders: Evidence from a Korea national cross-sectional survey.

This study aims to analyze the relationship between occupation and voice disorders using a national cross-sectional survey that represents the Korean population. Subjects were 5,407 members of the non-institutionalized population aged 19-59 (2,258 men, 3,149 women) who completed the laryngeal examination of the Korea National Health and Nutrition Examination Survey 2010-2012. Voice disorders were surveyed by classifying laryngeal pathologies and self-reported voice problems. Occupations were classified into 'managers & professionals', 'clerical support workers', 'service & sales workers', 'skilled agricultural & forestry & fishery workers', 'craft & plant and machine operators and assemblers', and 'unskilled laborers', based on the sixth Korean Standard Classification of Occupations. The results of the multinomial logistic regression analysis indicated that managers & professionals were 1.4 times (OR 1.42, 95% CI 1.01-2.01) more likely to have self-reported voice problems, and service & sales workers were 1.6 times (OR 1.62, 95% CI 1.14-2.30) more likely to have self-reported voice problems than economically inactive people (P < 0.05). Still, there was no significant association between the presence of laryngeal pathology and profession. Managers & professionals and service & sales workers may have a higher risk of voice problems than the economically inactive.

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

The absolute photoionization cross-section of the methyl radical has been measured using two completely independent methods. The CH3 photoionization cross-section was determined relative to that of acetone and methyl vinyl ketone at photon energies of 10.2 and 11.0 eV by using a pulsed laser-photolysis/time-resolved synchrotron photoionization mass spectrometry method. The time-resolved depletion of the acetone or methyl vinyl ketone precursor and the production of methyl radicals following 193 nm photolysis are monitored simultaneously by using time-resolved synchrotron photoionization mass spectrometry. Comparison of the initial methyl signal with the decrease in precursor signal, in combination with previously measured absolute photoionization cross-sections of the precursors, yields the absolute photoionization cross-section of the methyl radical; sigma(CH3)(10.2 eV) = (5.7 +/- 0.9) x 10(-18) cm(2) and sigma(CH3)(11.0 eV) = (6.0 +/- 2.0) x 10(-18) cm(2). The photoionization cross-section for vinyl radical determined by photolysis of methyl vinyl ketone is in good agreement with previous measurements. The methyl radical photoionization cross-section was also independently measured relative to that of the iodine atom by comparison of ionization signals from CH3 and I fragments following 266 nm photolysis of methyl iodide in a molecular-beam ion-imaging apparatus. These measurements gave a cross-section of (5.4 +/- 2.0) x 10(-18) cm(2) at 10.460 eV, (5.5 +/- 2.0) x 10(-18) cm(2) at 10.466 eV, and (4.9 +/- 2.0) x 10(-18) cm(2) at 10.471 eV. The measurements allow relative photoionization efficiency spectra of methyl radical to be placed on an absolute scale and will facilitate quantitative measurements of methyl concentrations by photoionization mass spectrometry.

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

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. Although statutes may not address specific procedures, upon challenge, there may be a possibility of sanctions depending on interpretation. Copyright © 2014 National University of Health Sciences.

Despite the potential benefit of primaquine in reducing Plasmodium falciparum transmission and radical cure of Plasmodium vivax and Plasmodium ovale infections, concerns over risk of hemolytic toxicity in individuals with glucose-6-phosphate dehydrogenase deficiency (G6PDd) have hampered its deployment. A cross-sectional survey was conducted in 2014 to assess the G6PDd prevalence among 631 children between 6 and 59 months of age in southwestern Uganda, an area where primaquine may be a promising control measure. G6PDd prevalence was determined using three detection methods: a quantitative G6PD enzyme activity assay (Trinity Biotech® G-6-PDH kit), a qualitative point-of-care test (CareStart™ G6PD rapid diagnostic test [RDT]), and molecular detection of the G6PD A− G202A allele. Qualitative tests were compared with the gold standard quantitative assay. G6PDd prevalence was higher by RDT (8.6%) than by quantitative assay (6.8%), using a < 60% activity threshold. The RDT performed optimally at a < 60% threshold and demonstrated high sensitivity (≥ 90%) and negative predictive values (100%) across three activity thresholds (below 60%, 30%, and 40%). G202A allele frequency was 6.4%, 7.9%, and 6.8% among females, males, and overall, respectively. Notably, over half of the G202A homo-/hemizygous children expressed ≥ 60% enzyme activity. Overall, the CareStart™ G6PD RDT appears to be a viable screening test to accurately identify individuals with enzyme activities below 60%. The low prevalence of G6PDd across all three diagnostic modalities and absence of severe deficiency in our study suggests that there is little barrier to the use of single-dose primaquine in this region.

Leptospirosis is a widespread but under-reported cause of morbidity and mortality. Global re-emergence of leptospirosis has been associated with the growth of informal urban settlements in which rodents are thought to be important reservoir hosts. Understanding the multi-host epidemiology of leptospirosis is essential to control and prevent disease. A cross-sectional survey of rodents in the Kibera settlement in Nairobi, Kenya was conducted in September–October 2008 to demonstrate the presence of pathogenic leptospires. A real-time quantitative polymerase chain reaction showed that 41 (18.3%) of 224 rodents carried pathogenic leptospires in their kidneys, and sequence data identified Leptospira interrogans and L. kirschneri in this population. Rodents of the genus Mus (37 of 185) were significantly more likely to be positive than those of the genus Rattus (4 of 39; odds ratio = 15.03). Questionnaire data showed frequent contact between humans and rodents in Kibera. This study emphasizes the need to quantify the public health impacts of this neglected disease at this and other urban sites in Africa. PMID:24080637

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

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.

The Achilles tendon is one of the most commonly observed tendons injured with a variety of causes, such as trauma, overuse and degeneration, in the human body. Rupture and tendinosis are relatively common for this strong tendon. Stress-strain properties and shape change are important biomechanical properties of the tendon to assess surgical repair or healing progress. Currently, there are rather limited non-invasive methods available for precisely quantifying the in vivo biomechanical properties of the tendons. The aim of this study was to apply quantitative ultrasound (QUS) methods, including ultrasonic attenuation and speed of sound (SOS), to investigate porcine tendons in different stress-strain conditions. In order to find a reliable method to evaluate the change of tendon shape, ultrasound measurement was also utilized for measuring tendon thickness and compared with the change in tendon cross-sectional area under different stress. A total of 15 porcine tendons of hind trotters were examined. The test results show that the attenuation and broadband ultrasound attenuation decreased and the SOS increased by a smaller magnitude as the uniaxial loading of the stress-strain upon tendons increased. Furthermore, the tendon thickness measured with the ultrasound method was significantly correlated with tendon cross-sectional area (Pearson coefficient = 0.86). These results also indicate that attenuation of QUS and ultrasonic thickness measurement are reliable and potential parameters for assessing biomechanical properties of tendons. Further investigations are needed to warrant the application of the proposed method in a clinical setting.

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.

MRV is an important blood vessel imaging and diagnostic tool for the evaluation of stenosis, occlusions, or aneurysms. However, an accurate image-processing tool for vessel comparison is unavailable. The purpose of this study was to develop and test an automated technique for vessel cross-sectional analysis. An algorithm for vessel cross-sectional analysis was developed that included 7 main steps: 1) image registration, 2) masking, 3) segmentation, 4) skeletonization, 5) cross-sectional planes, 6) clustering, and 7) cross-sectional analysis. Phantom models were used to validate the technique. The method was also tested on a control subject and a patient with idiopathic intracranial hypertension (4 large sinuses tested: right and left transverse sinuses, superior sagittal sinus, and straight sinus). The cross-sectional area and shape measurements were evaluated before and after lumbar puncture in patients with idiopathic intracranial hypertension. The vessel-analysis algorithm had a high degree of stability with <3% of cross-sections manually corrected. All investigated principal cranial blood sinuses had a significant cross-sectional area increase after lumbar puncture (P ≤ .05). The average triangularity of the transverse sinuses was increased, and the mean circularity of the sinuses was decreased by 6% ± 12% after lumbar puncture. Comparison of phantom and real data showed that all computed errors were <1 voxel unit, which confirmed that the method provided a very accurate solution. In this article, we present a novel automated imaging method for cross-sectional vessels analysis. The method can provide an efficient quantitative detection of abnormalities in the dural sinuses. © 2016 by American Journal of Neuroradiology.

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

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.

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

Objectives To deliver an estimate of bullying among residents and fellows in the United States graduate medical education system and to explore its prevalence within unique subgroups. Design/Setting/Participants A national cross-sectional survey from a sample of residents and fellows who completed an online bullying survey conducted in June 2015. The survey was distributed using a chain sampling method that relied on electronic referrals from 4,055 training programs, with 1,791 residents and fellows completing the survey in its entirety. Survey respondents completed basic demographic and programmatic information plus four general bullying and 20 specific bullying behavior questions. Between-group differences were compared for demographic and programmatic stratifications. Main Outcomes/Measures Self-reported subjected to workplace bullying from peers, attendings, nurses, ancillary staff, or patients in the past 12 months. Results Almost half of the respondents (48%) reported being subjected to bullying although both those subjected and not subjected reported experiencing ≥ 1 bullying behaviors (95% and 39% respectively). Attendings (29%) and nurses (27%) were the most frequently identified source of bullying, followed by patients, peers, consultants and staff. Attempts to belittle and undermine work and unjustified criticism and monitoring of work were the most frequently reported bullying behaviors (44% each), followed by destructive innuendo and sarcasm (37%) and attempts to humiliate (32%). Specific bullying behaviors were more frequently reported by female, non-white, shorter than < 5’8 and BMI ≥ 25 individuals. Conclusions/Relevance Many trainees report experiencing bullying in the United States graduate medical education programs. Including specific questions on bullying in the Accreditation Council for Graduate Medical Education annual resident/fellow survey, implementation of anti-bullying policies, and a multidisciplinary approach engaging all

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.

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

Background Musculoskeletal impairment (MSI) is an important cause of morbidity and mortality worldwide, especially in developing countries. Prevalence studies for MSI in the developing world have used varying methodologies and are seldom directly comparable. This study aimed to develop a new tool to screen for and diagnose MSI and to pilot test the methodology for a national survey in Rwanda. Methods A 7 question screening tool to identify cases of MSI was developed through literature review and discussions with healthcare professionals. To validate the tool, trained rehabilitation technicians screened 93 previously identified gold standard 'cases' and 86 'non cases'. Sensitivity, specificity and positive predictive value were calculated. A standardised examination protocol was developed to determine the aetiology and diagnosis of MSI for those who fail the screening test. For the national survey in Rwanda, multistage cluster random sampling, with probability proportional to size procedures will be used for selection of a cross-sectional, nationally representative sample of the population. Households to be surveyed will be chosen through compact segment sampling and all individuals within chosen households will be screened. A pilot survey of 680 individuals was conducted using the protocol. Results: The screening tool demonstrated 99% sensitivity and 97% specificity for MSI, and a positive predictive value of 98%. During the pilot study 468 out of 680 eligible subjects (69%) were screened. 45 diagnoses were identified in 38 persons who were cases of MSI. The subjects were grouped into categories based on diagnostic subgroups of congenital (1), traumatic (17), infective (2) neurological (6) and other acquired(19). They were also separated into mild (42.1%), moderate (42.1%) and severe (15.8%) cases, using an operational definition derived from the World Health Organisation's International Classification of Functioning, Disability and Health.

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

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.

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 critical care context presents important opportunities for nurses to deliver skilled, comprehensive care to patients at the end of life and their families. Limited research has identified the actual end-of-life care practices of critical care nurses. To identify the end-of-life care practices of critical care nurses. A national cross-sectional online survey. The survey was distributed to members of an Australian critical care nursing association and 392 critical care nurses (response rate 25%) completed the survey. Exploratory factor analysis using principal axis factoring with oblique rotation was undertaken on survey responses to identify the domains of end-of-life care practice. Descriptive statistics were calculated for individual survey items. Exploratory factor analysis identified six domains of end-of-life care practice: information sharing, environmental modification, emotional support, patient and family centred decision-making, symptom management and spiritual support. Descriptive statistics identified a high level of engagement in information sharing and environmental modification practices and less frequent engagement in items from the emotional support and symptom management practice areas. The findings of this study identified domains of end-of-life care practice, and critical care nurse engagement in these practices. The findings highlight future training and practice development opportunities, including the need for experiential learning targeting the emotional support practice domain. Further research is needed to enhance knowledge of symptom management practices during the provision of end-of-life care to inform and improve practice in this area.

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

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

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

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. 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. 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. 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. Transactional sex is associated with sexual coercion and HIV risk behaviors such as multiple concurrent sexual partnerships among young people in Uganda. In addition, transactional sex appears to place young men at increased

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

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.

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

Developing Scientific Reasoning Through Drawing Cross-Sections

NASA Astrophysics Data System (ADS)

Hannula, K. A.

2012-12-01

Cross-sections and 3D models of subsurface geology are typically based on incomplete information (whether surface geologic mapping, well logs, or geophysical data). Creating and evaluating those models requires spatial and quantitative thinking skills (including penetrative thinking, understanding of horizontality, mental rotation and animation, and scaling). However, evaluating the reasonableness of a cross-section or 3D structural model also requires consideration of multiple possible geometries and geologic histories. Teaching students to create good models requires application of the scientific methods of the geosciences (such as evaluation of multiple hypotheses and combining evidence from multiple techniques). Teaching these critical thinking skills, especially combined with teaching spatial thinking skills, is challenging. My Structural Geology and Advanced Structural Geology courses have taken two different approaches to developing both the abilities to visualize and to test multiple models. In the final project in Structural Geology (a 3rd year course with a pre-requisite sophomore mapping course), students create a viable cross-section across part of the Wyoming thrust belt by hand, based on a published 1:62,500 geologic map. The cross-section must meet a number of geometric criteria (such as the template constraint), but is not required to balance. Each student tries many potential geometries while trying to find a viable solution. In most cases, the students don't visualize the implications of the geometries that they try, but have to draw them and then erase their work if it does not meet the criteria for validity. The Advanced Structural Geology course used Midland Valley's Move suite to test the cross-sections that they made in Structural Geology, mostly using the flexural slip unfolding algorithm and testing whether the resulting line lengths balanced. In both exercises, students seemed more confident in the quality of their cross-sections when the

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.

The present study, taking a resource-oriented approach to mental health, aimed at investigating mental resilience and its determinants among undergraduate physiotherapy students using quantitative and qualitative tools. A questionnaire-based cross-sectional survey supplemented by 2 focus groups. One university in Hungary. 130 physiotherapy students at years 1, 2, and 3. Sense of coherence, a measure of dynamic self-esteem, as well as social support from family and peers were used to assess mental well-being. A screening instrument for psychological morbidity and perceived stress were used as deficiency-oriented approaches. Student opinions were gathered on positive and negative determinants of mental health. Resilience was lower [mean difference 4.8 (95% CI -3.4; 13.1)], and the occurrence of psychological morbidity (32.5% vs. 0%) was higher among female compared to male students. However, the proportion of students fully supported by their peers was higher among females (63% vs. 37.5%). Female students, unlike their male counterparts, experienced higher stress compared to their peers in the general population. Social support declined as students progressed in their studies though this proved to be the most important protective factor for their mental well-being. Results were fed back to the course organizers recommending the implementation of an evidence-based method to improve social support as delineated by the Guide to Community Preventive Services of the US the outcomes of which are to be seen in the future.

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

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.

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.

Bergh, Ingrid H E; Ek, Kristina; Mårtensson, Lena B

2013-06-01

Assessment of women's labor pain is seldom acknowledged in clinical practice or research. The words "aching" and "hurting" are frequently used by women to describe childbirth pain. The aim of this study was to determine the quantitative meanings midwifery students attribute to the terms "hurt", "ache" and "pain". Data was collected by self-administered questionnaire from students at seven Swedish midwifery programs. A total of 230 filled out and returned a completed questionnaire requesting them to rate, on a visual analog scale, the intensity of "hurt", "ache" or "pain" in the back, as reported by a fictitious parturient. The midwifery students attributed, with substantial individual variation, different quantitative meanings to the studied pain descriptors. To be able to communicate about pain with a woman in labor, it is essential that the midwife be familiar with the value of different words and what they mean to her as this may affect her assessment when the woman describes her pain.

Neutron Fission of 235,237,239U and 241,243Pu: Cross Sections, Integral Cross Sections and Cross Sections on Excited States

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

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

Although stroke is the fourth cause of death in Western societies, public stroke awareness remains suboptimal. The aim of this study was to estimate stroke risk perception and stroke awareness in Greece through a cross-sectional telephone survey. A trained interview team conducted this cross-sectional telephone survey between February and April 2014 using an online structured questionnaire. Participants were selected using random digit dialing of landline and mobile telephone numbers with quota sampling weighted for geographical region based on the most recent General Population Census (2011). Between February and April 2014, 723 individuals (418 women [58%], 47.4 ± 17.8 years) agreed to respond. Among all respondents, 642 (88.8%) were able to provide at least 1 stroke risk factor; 673 respondents (93.08%) were able to provide correctly at least 1 stroke symptom or sign. When asked what would they do in case of acute onset of stroke symptoms, 497 (68.7%) responded that they would either call the ambulance or visit the closest emergency department. Only 35.3%, 18.9%, 17.2%, 20.7%, and 15.0% of respondents with atrial fibrillation, arterial hypertension, dyslipidemia, diabetes mellitus, and current smoking, respectively, considered themselves as being in high risk for stroke. Stroke risk perception in Greece is low despite moderate public stroke awareness. Copyright © 2015 National Stroke Association. Published by Elsevier Inc. All rights reserved.

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.

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.

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.

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.

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.

Icelandic Physical Therapists' Attitudes Toward Adoption of New Knowledge and Evidence-Based Practice: Cross-Sectional Web-Based Survey.

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

Optical absorption is the most fundamental optical property characterizing light–matter interactions in materials and can be most readily compared with theoretical predictions. However, determination of optical absorption cross-section of individual nanostructures is experimentally challenging due to the small extinction signal using conventional transmission measurements. Recently, dramatic increase of optical contrast from individual carbon nanotubes has been successfully achieved with a polarization-based homodyne microscope, where the scattered light wave from the nanostructure interferes with the optimized reference signal (the reflected/transmitted light). Here we demonstrate high-sensitivity absorption spectroscopy for individual single-walled carbon nanotubes by combining the polarization-based homodyne technique with broadband supercontinuum excitation in transmission configuration. To our knowledge, this is the first time that high-throughput and quantitative determination of nanotube absorption cross-section over broad spectral range at the single-tube level was performed for more than 50 individual chirality-defined single-walled nanotubes. Our data reveal chirality-dependent behaviors of exciton resonances in carbon nanotubes, where the exciton oscillator strength exhibits a universal scaling law with the nanotube diameter and the transition order. The exciton linewidth (characterizing the exciton lifetime) varies strongly in different nanotubes, and on average it increases linearly with the transition energy. In addition, we establish an empirical formula by extrapolating our data to predict the absorption cross-section spectrum for any given nanotube. The quantitative information of absorption cross-section in a broad spectral range and all nanotube species not only provides new insight into the unique photophysics in one-dimensional carbon nanotubes, but also enables absolute determination of optical quantum efficiencies in important

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.

Several total and partial photoionization cross section calculations, based on both theoretical and empirical approaches, are quantitatively evaluated with statistical analyses using a large collection of experimental data retrieved from the literature to identify the state of the art for modeling the photoelectric effect in Monte Carlo particle transport. Some of the examined cross section models are available in general purpose Monte Carlo systems, while others have been implemented and subjected to validation tests for the first time to estimate whether they could improve the accuracy of particle transport codes. The validation process identifies Scofield's 1973 non-relativistic calculations, tabulated in the Evaluated Photon Data Library (EPDL), as the one best reproducing experimental measurements of total cross sections. Specialized total cross section models, some of which derive from more recent calculations, do not provide significant improvements. Scofield's non-relativistic calculations are not surpassed regarding the compatibility with experiment of K and L shell photoionization cross sections either, although in a few test cases Ebel's parameterization produces more accurate results close to absorption edges. Modifications to Biggs and Lighthill's parameterization implemented in Geant4 significantly reduce the accuracy of total cross sections at low energies with respect to its original formulation. The scarcity of suitable experimental data hinders a similar extensive analysis for the simulation of the photoelectron angular distribution, which is limited to a qualitative appraisal.

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 development of new therapeutic agents for the treatment of Duchenne muscular dystrophy has put a focus on defining outcome measures most sensitive to capture treatment effects. This cross-sectional analysis investigates the relation between validated clinical assessments such as the 6-minute walk test, motor function measure and quantitative muscle MRI of thigh muscles in ambulant Duchenne muscular dystrophy patients, aged 6.5 to 10.8 years (mean 8.2, SD 1.1). Quantitative muscle MRI included the mean fat fraction using a 2-point Dixon technique, and transverse relaxation time (T2) measurements. All clinical assessments were highly significantly inter-correlated with p < 0.001. The strongest correlation with the motor function measure and its D1-subscore was shown by the 6-minute walk test. Clinical assessments showed no correlation with age. Importantly, quantitative muscle MRI values significantly correlated with all clinical assessments with the extensors showing the strongest correlation. In contrast to the clinical assessments, quantitative muscle MRI values were highly significantly correlated with age. In conclusion, the motor function measure and timed function tests measure disease severity in a highly comparable fashion and all tests correlated with quantitative muscle MRI values quantifying fatty muscle degeneration.

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.

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.

Introduction According to the Ethiopian Health Sector Development Plan IV annual performance report (HSDP IV), Ethiopia targeted to reach 90% coverage with DPT-Hib-HepB 3 (Pentavalent3) vaccine and 86% coverage with measles vaccine in 2010- 2011. However, the actual performance fell-short of the intended targets due to several reasons. Therefore, a nationwide comprehensive study was conducted to examine the behavioral determinants of immunization practices in the Ethiopian context. The study employed the Modified Steps of Behavioral Change (SBC) Model as a theoretical lens. Methods A cross-sectional study was conducted in May 2012 in all the nine regions and the two city administrations of Ethiopia. The study used a community-based quantitative survey design comprising of multistage cluster sampling to draw relevant data from a sample of 2,328 caretakers whose children were 12-23 months of age at the time of data collection. Results Overall, the multivariate analysis findings revealed that caretakers, who had high knowledge were 2.24 times more likely to vaccinate their children than participants had low knowledge (OR= 2.24, 95%CI: 1.68-2.98). Participants who had high approval were 2.45 times more likely to vaccinate their children than participants who had unfavorable approval (OR= 2.45, 95%CI: 1.67-3.59); and participants who had high intention were 6.49 times more likely to vaccinate their children with pentavalent3 vaccines than participants who had low intention(OR= 6.49, 95%CI: 4.83-8). Also, it was clear from the regression analysis that aspects of caretakers' demographic characteristics were significant predictors of their immunization practice for the sample group. Conclusion We identified that caretakers' knowledge, approval, intention, parents' residence, and religious backgrounds were associated with immunization service utilization. To achieve sustainable behavioral change on immunization service utilization of the caretakers in Ethiopia, this study

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.

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.

Little population-based work has been published about the mental health of adolescents with both sexual/gender (SG) and ethnic minority (i.e. double minority) status. This study aimed to provide an overview on their mental health. Analysis of data from a total of 17,607 high school students from New Zealand's 2007 and 2012 cross-sectional nationally representative Adolescent Health Surveys, including a total of 1306 (7.4%) SG minority participants, of whom 581 (3.3%) were also an ethnic minority. SG minority status, minority ethnicity, and female sex were associated with higher mental distress and poorer well-being. Generally speaking, double minority students reported poorer mental health than SG majority students of the same ethnicity, but reported better mental health than SG minority New Zealand European students. Explanations and future directions for research were suggested to further explore how double minority students negotiate mental health in the context of their communities/cultures in New Zealand.

Vertically stabilized elongated cross-section tokamak

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.

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

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

HIV infection has been associated with increased risk of osteoporosis and fragility fractures. Dual-energy X-ray absorptiometry (DXA) is the reference standard to assess bone mineral density (BMD); however, it is not easily accessible in several settings. Heel Quantitative ultrasound (QUS) is a radiation-free, easy-to-perform technique, which may help reducing the need for DXA. In this cross-sectional study, we used heel QUS (Hologic Sahara(®)) to assess bone status in a cohort of HIV-infected patients. A QUS stiffness index (QUI) threshold >83 was used to identify patients with a low likelihood of osteoporosis. Moreover, we compared QUS results with those of 36 sex- and age-matched HIV-negative controls. 244 HIV-positive patients were enrolled. Median heel QUI value was 83 (73-96) vs. 93 (IQR 84-104) in the control group (p = 0.04). 110 patients (45 %) had a QUI value ≤83. Risk factors for low QUI values were age (OR 1.04 per year, 95 % CI 1.01-1.07, p = 0.004), current use of protease inhibitors (OR 1.85, CI 1.03-3.35, p = 0.039), current use of tenofovir (OR 2.28, CI 1.22-4.27, p = 0.009) and the number of risk factors for secondary osteoporosis (OR 1.46, CI 1.09-1.95, p = 0.01). Of note, QUI values were significantly correlated with FRAX score (r = -0.22, p = 0.004). According to EACS guidelines, 45 % of patients had risk factors for osteoporosis which make them eligible for DXA. By using QUS, we may avoid DXA in around half of them. As HIV-positive patients are living longer, the prevalence of osteoporosis is expected to increase over time. Appropriate screening, prevention and treatment are crucial to preserve bone health in this population. The use of screening techniques, such as heel QUS, may help reducing the need for DXA. Further studies are needed to define the diagnostic accuracy of this promising technique in the setting of HIV.

Abstract Background In 2015, more than 1 million refugees arrived in Europe. During their travels, refugees often face harsh conditions, violence and torture in transit countries, but there is a lack of quantitative evidence on their experiences. We present the results of a retrospective survey among refugees in the ‘Jungle’ of Calais, France, to document their health problems and the violence they endured during their journeys. Methods We conducted a cross-sectional population-based survey in November and December 2015. The sample size was set at 402 individuals, and geospatial simple random sampling was used. We collected data on demographics, routes travelled, health status, violence and future plans. Results Departures from the country of origin increased beginning in September 2015. Sixty-one percent of respondents reported having at least one health problem, especially while in Calais. Overall, 65.6% (95% CI 60.3–70.6) experienced at least one violent event en route; 81.5% of refugees wanted to go to the UK. Conclusions This first quantitative survey conducted among refugees in Europe provides important socio-demographic data on refugees living in Calais and describes the high rate of violence they encountered during their journeys. Similar documentation should be repeated throughout Europe in order to better respond to the needs of this vulnerable population. PMID:29325099

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

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.

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.

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. PMID:26035665

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.

Rundberg, Robert S.

The neutron activation of components in a nuclear device can provide useful signatures of weapon design or sophistication. This lecture will cover some of the basics of neutron reaction cross sections. Nuclear reactor cross sections will also be presented to illustrate the complexity of convolving neutron energy spectra with nuclear excitation functions to calculate useful effective reactor cross sections. Deficiencies in the nuclear database will be discussed along with tools available at Los Alamos to provide new neutron cross section data.

Two-Photon Excitation, Fluorescence Microscopy, and Quantitative Measurement of Two-Photon Absorption Cross Sections

NASA Astrophysics Data System (ADS)

DeArmond, Fredrick Michael

As optical microscopy techniques continue to improve, most notably the development of super-resolution optical microscopy which garnered the Nobel Prize in Chemistry in 2014, renewed emphasis has been placed on the development and use of fluorescence microscopy techniques. Of particular note is a renewed interest in multiphoton excitation due to a number of inherent properties of the technique including simplified optical filtering, increased sample penetration, and inherently confocal operation. With this renewed interest in multiphoton fluorescence microscopy, comes an increased demand for robust non-linear fluorescent markers, and characterization of the associated tool set. These factors have led to an experimental setup to allow a systematized approach for identifying and characterizing properties of fluorescent probes in the hopes that the tool set will provide researchers with additional information to guide their efforts in developing novel fluorophores suitable for use in advanced optical microscopy techniques as well as identifying trends for their synthesis. Hardware was setup around a software control system previously developed. Three experimental tool sets were set up, characterized, and applied over the course of this work. These tools include scanning multiphoton fluorescence microscope with single molecule sensitivity, an interferometric autocorrelator for precise determination of the bandwidth and pulse width of the ultrafast Titanium Sapphire excitation source, and a simplified fluorescence microscope for the measurement of two-photon absorption cross sections. Resulting values for two-photon absorption cross sections and two-photon absorption action cross sections for two standardized fluorophores, four commercially available fluorophores, and ten novel fluorophores are presented as well as absorption and emission spectra.

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.

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.

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

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.

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

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

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

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

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.

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.

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.

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.

Africa is in an orphan-care crisis. In Zimbabwe, where one-fourth of adults are HIV-positive and one-fifth of children are orphans, AIDS and economic decline are straining society's ability to care for orphans within their extended families. Lack of stable care is putting thousands of children at heightened risk of malnourishment, emotional underdevelopment, illiteracy, poverty, sexual exploitation, and HIV infection, endangering the future health of the society they are expected to sustain. To explore barriers and possible incentives to orphan care, a quantitative cross-sectional survey in rural eastern Zimbabwe asked 371 adults caring for children, including 212 caring for double orphans, about their well-being, needs, resources, and perceptions and experiences of orphan care. Survey responses indicate that: 1) foster caregivers are disproportionately female, older, poor, and without a spouse; 2) 98% of non-foster caregivers are willing to foster orphans, many from outside their kinship network; 3) poverty is the primary barrier to fostering; 4) financial, physical, and emotional stress levels are high among current and potential fosterers; 5) financial need may be greatest in single-orphan AIDS-impoverished households; and 6) struggling families lack external support. Incentives for sustainable orphan care should focus on financial assistance, starting with free schooling, and development of community mechanisms to identify and support children in need, to evaluate and strengthen families' capacity to provide orphan care, and to initiate and support placement outside the family when necessary.

The concrete application of research findings in nursing practice is a multidimensional process. In Austria, there are currently no results available that explain the impact of and association with the implementation of research in hospitals. The aim of the study was to investigate influences and relationships of individual attitudes towards research utilization, availability of research results and institutional support of nurses in Austrian hospitals with respect to research application. In a non-experimental quantitative cross-sectional design a multi-centre study (n = 10) was performed in 2011. The sample comprises 178 certified nurses who were interviewed with a survey questionnaire. The multiple regression analysis shows that a positive attitude towards research use (β = 0.388, p < 0.001), the availability of processed research results (β = 0.470, p < 0.001), and an adequate institutional support (β = 0.142, p < 0.050) has a significant influence on the application of research results. The path analysis proves that course attendance in evidence-based nursing has a strong positive influence towards research application (β = 0.464; p < 0.001). Health institutions are, according to legal instructions, called on to make use of the positive attitude and supply supporting measures in order to introduce research results into the daily nursing practice.

We use optical trapping to continuously bend an isolated microtubule while simultaneously measuring the applied force and the resulting filament strain, thus allowing us to determine its elastic properties over a wide range of applied strains. We find that, while in the low-strain regime, microtubules may be quantitatively described in terms of the classical Euler-Bernoulli elastic filament, above a critical strain they deviate from this simple elastic model, showing a softening response with increasing deformations. A three-dimensional thin-shell model, in which the increased mechanical compliance is caused by flattening and eventual buckling of the filament cross-section, captures this softening effectmore » in the high strain regime and yields quantitative values of the effective mechanical properties of microtubules. Our results demonstrate that properties of microtubules are highly dependent on the magnitude of the applied strain and offer a new interpretation for the large variety in microtubule mechanical data measured by different methods.« less

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.

Mei, B.; Tu, X. L.; Wang, M.

2018-04-01

An evident odd-even staggering (OES) in fragment cross sections has been experimentally observed in many fragmentation and spallation reactions. However, quantitative comparisons of this OES effect in different reaction systems are still scarce for neutron-rich nuclei near the neutron drip line. By employing a third-order difference formula, the magnitudes of this OES in extensive experimental cross sections are systematically investigated for many neutron-rich nuclei with (N -Z ) from 1 to 23 over a broad range of atomic numbers (Z ≈3 -50 ). A comparison of these magnitude values extracted from fragment cross sections measured in different fragmentation and spallation reactions with a large variety of projectile-target combinations over a wide energy range reveals that the OES magnitude is almost independent of the projectile-target combinations and the projectile energy. The weighted average of these OES magnitudes derived from cross sections accurately measured in different reaction systems is adopted as the evaluation value of the OES magnitude. These evaluated OES magnitudes are recommended to be used in fragmentation and spallation models to improve their predictions for fragment cross sections.

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.

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.

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.

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

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.

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

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.

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.

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

We aimed to define characteristics and needs of Facebook users in relation to congenital anomalies. Cross-sectional analysis of Facebook related to four congenital anomalies: anorectal malformation (ARM), congenital diaphragmatic hernia (CDH), congenital heart disease (CHD) and hypospadias/epispadias (HS/ES). A keyword search was performed to identify relevant Groups/Pages. An anonymous survey was posted to obtain quantitative/qualitative data on users and their healthcare needs. 54 Groups and 24 Pages were identified (ARM: 10 Groups; CDH: 9 Groups, 7 Pages; CHD: 32 Groups, 17 Pages; HS/ES: 3 Groups), with 16,191 Group members and 48,766 Page likes. 868/1103 (79%) of respondents were parents.

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

2012-03-01

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

With recent advancement in hardware of optoacoustic imaging systems, highly detailed cross-sectional images may be acquired at a single laser shot, thus eliminating motion artifacts. Nonetheless, other sources of artifacts remain due to signal distortion or out-of-plane signals. The purpose of image reconstruction algorithms is to obtain the most accurate images from noisy, distorted projection data. In this paper, the authors use the model-based approach for acoustic inversion, combined with a sparsity-based inversion procedure. Specifically, a cost function is used that includes the L1 norm of the image in sparse representation and a total variation (TV) term. The optimization problem is solved by a numerically efficient implementation of a nonlinear gradient descent algorithm. TV-L1 model-based inversion is tested in the cross section geometry for numerically generated data as well as for in vivo experimental data from an adult mouse. In all cases, model-based TV-L1 inversion showed a better performance over the conventional Tikhonov regularization, TV inversion, and L1 inversion. In the numerical examples, the images reconstructed with TV-L1 inversion were quantitatively more similar to the originating images. In the experimental examples, TV-L1 inversion yielded sharper images and weaker streak artifact. The results herein show that TV-L1 inversion is capable of improving the quality of highly detailed, multiscale optoacoustic images obtained in vivo using cross-sectional imaging systems. As a result of its high fidelity, model-based TV-L1 inversion may be considered as the new standard for image reconstruction in cross-sectional imaging.

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.

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.

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. PA levels among professional college students in North India have been established. PMID:29511653

To evaluate the quality of doctoral education in nursing in the United Kingdom. In recent decades, doctoral education programmes in nursing are increasing worldwide. There are many reasons for this and concerns have been raised regarding the quality of provision in and across countries. To date, the quality of doctoral education on a global level has not been reported in the literature. This United Kingdom study is part of a seven country investigation into the quality of doctoral education in nursing (Australia, Japan, Korea, South Africa, Thailand, United Kingdom and United States of America). A quantitative study using a cross-sectional comparative survey design. An online survey was administered to collect the views of doctoral students and staff members on four domains: programme, faculty/staff, resource and evaluation. The study was carried out between 2010-2012. In most cases, staff perceived these more positively than students and the differences in perception were often statistically significant. Interestingly, many students rated the quality of supervision as excellent, whereas no staff member rated supervision this highly. The crucial importance of resources was confirmed in the path analysis of the four Quality of Doctoral Nursing Education domains. This demonstrates that investment in resources is much more cost-effective than investment in the other domains in relation to improving the overall quality of doctoral education in nursing. This study has wide-ranging implications for how the quality of doctoral education is monitored and enhanced. © 2013 John Wiley & Sons Ltd.

The shortage of nurses is a global problem. One strategy for producing more registered nurses worldwide and in Israel in particular is to offer graduate entry nursing programs for individuals with non-nursing academic degrees. In order to recruit academic degree holders into the nursing profession, it is important to identify factors that might attract them. The purpose of this study was to explore whether the perception of nurse characteristics by academic degree holders is associated with their interest in enrolling in a graduate entry nursing program or in recommending this program to a family member, and whether ethnic background, gender and interaction with a nurse have an effect on this interest. A cross-sectional quantitative study. The setting of the study was on the campus of Tel Aviv University. A convenience sample of 522 individuals with an academic education, men and women, aged 18-60 and equally distributed between Jewish and Arab Israelis, took part in the study. Participants completed a questionnaire based on the Porter Nursing Image Scale. A moderate positive correlation was found between perception of nurses and interest in nursing (r=0.32, p<0.01). Arab Israelis, women, and individuals who have or have had interactions with nurses, viewed nurses in a more positive light and had a higher interest in nursing than their counterparts. Efforts should be made to foster a positive public image of nursing among the population of people with an academic education. Recruitment strategies should be tailored to each of this population's subgroups. Copyright © 2015 Elsevier Ltd. All rights reserved.

Both media use and cancer knowledge have been identified as important predictors of a healthy lifestyle. However, little is known about the interplay between these two variables, and about differences between cancer diagnosed and non-diagnosed consumers of media and knowledge. This study investigated the relationship between media use (television and internet exposure) and lifestyle choices of cancer diagnosed and non-diagnosed individuals, and looked at the influence of cancer knowledge on this relationship. A cross-sectional, quantitative survey (the Leuven Cancer Information Survey) was administered to 621 cancer diagnosed and 1387 non-diagnosed individuals, aged 16-88 years old in Flanders (Belgium). Bivariate analyses, hierarchical linear regression analyses and advanced moderation and mediation analyses were conducted. Internet exposure was not a predictor of lifestyle choices. Television exposure, however, was a negative predictor of healthy lifestyle choices. Moreover, television exposure was a direct negative predictor of cancer knowledge, which in turn positively predicted lifestyle choices. However, no differences were found in the investigated relationships between the two subsamples. These results indicate that higher levels of television exposure coincide with less cancer knowledge and with less healthy lifestyle choices. It offers a pathway for intervention by suggesting that improving cancer knowledge through television might positively affect lifestyle choices. © The Author 2015.

The aim of this study was to investigate associations between poor spinal posture and the recurrence of major depressive episodes and severity of symptoms in patients with major depressive disorder (MDD). This was a cross-sectional quantitative study of MDD patients. Outpatients were recruited from consecutive admissions at a mood disorders unit of a tertiary psychiatric hospital. Of 136 MDD patients, 72 (53 women, 19 men; mean age, 42.4±9.1years) met all the criteria and completed the study. Forty-one patients were classified with a recurrent episode (RE) of MDD and 31 with a single episode (SE). Quantitative assessments of postural deviations were made using photogrammetry, including kyphosis, shoulder protraction, and head inclination. The severity of depressive episodes was assessed using the Hamilton Depression Rating Scale. The diagnosis and classification of patients were performed according to DSM-IV-TR and SCID criteria. Multivariate analysis of variance indicated that the RE group had greater anterior head inclination (35.39; SD: 1.57), greater scapular abduction (1.69; SD: 0.93), and worse thoracic kyphosis (139.38; SD: 1.19) than the SE group (p<0.001 for all). Multivariate analysis of covariance showed an interaction between the severity of depressive symptoms and the degree of thoracic kyphosis (p=0.002). Recurrence of depressive episodes is associated with measures of postural misalignment. Copyright © 2016 Elsevier B.V. All rights reserved.

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.

Quantifying and predicting interpretational uncertainty in cross-sections

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

Electrical impedance myography and quantitative ultrasound are two noninvasive, painless, and effort-independent approaches for assessing neuromuscular disease. Both techniques have potential to serve as useful biomarkers in clinical trials in Duchenne muscular dystrophy. However, their comparative sensitivity to disease status and how they relate to one another are unknown. We performed a cross-sectional analysis of electrical impedance myography and quantitative ultrasound in 24 healthy boys and 24 with Duchenne muscular dystrophy, aged 2 to 14 years with trained research assistants performing all measurements. Three upper and three lower extremity muscles were studied unilaterally in each child, and the data averaged for each individual. Both electrical impedance myography and quantitative ultrasound differentiated healthy boys from those with Duchenne muscular dystrophy (P < 0.001 for both). Quantitative ultrasound values correlated with age in Duchenne muscular dystrophy boys (rho = 0.45; P = 0.029), whereas electrical impedance myography did not (rho = -0.31; P = 0.14). However, electrical impedance myography phase correlated with age in healthy boys (rho = 0.51; P = 0.012), whereas quantitative ultrasound did not (rho = -0.021; P = 0.92). In Duchenne muscular dystrophy boys, electrical impedance myography phase correlated with the North Star Ambulatory Assessment (rho = 0.65; P = 0.022); quantitative ultrasound revealed a near-significant association (rho = -0.56; P = 0.060). The two technologies trended toward a moderate correlation with one another in the Duchenne muscular dystrophy cohort but not in the healthy group (rho = -0.40; P = 0.054 and rho = -0.32; P = 0.13, respectively). Electrical impedance myography and quantitative ultrasound are complementary modalities for the assessment of boys with Duchenne muscular dystrophy; further study and application of these two modalities alone or in combination in a longitudinal fashion are warranted.

Chemical cross-linking mass spectrometry (XL-MS) provides protein structural information by identifying covalently linked proximal amino acid residues on protein surfaces. The information gained by this technique is complementary to other structural biology methods such as x-ray crystallography, NMR and cryo-electron microscopy[1]. The extension of traditional quantitative proteomics methods with chemical cross-linking can provide information on the structural dynamics of protein structures and protein complexes. The identification and quantitation of cross-linked peptides remains challenging for the general community, requiring specialized expertise ultimately limiting more widespread adoption of the technique. We describe a general method for targeted quantitative mass spectrometric analysis of cross-linked peptide pairs. We report the adaptation of the widely used, open source software package Skyline, for the analysis of quantitative XL-MS data as a means for data analysis and sharing of methods. We demonstrate the utility and robustness of the method with a cross-laboratory study and present data that is supported by and validates previously published data on quantified cross-linked peptide pairs. This advance provides an easy to use resource so that any lab with access to a LC-MS system capable of performing targeted quantitative analysis can quickly and accurately measure dynamic changes in protein structure and protein interactions.

Medical student educators play critical roles in evidence-based healthcare (EBHC) teaching and learning and as role models practicing EBHC. This study assessed their confidence to practice and teach EBHC, their attitude to EBHC and barriers to practicing and teaching EBHC. We conducted a cross-sectional online survey of educators of undergraduate medical students at a South African academic institution. STATA 12 was used for quantitative data analysis. Responses to open-ended questions were coded, and further interpretation done using thematic content analysis. Forty two (19%) educators from various departments responded to the invitation sent to everyone formally involved in teaching undergraduate medical students. They had high levels of knowledge and understanding of EBHC. Many had received training in teaching and learning approaches, although EBHC training received was mainly on enabling competencies. Limitations to practicing EBHC included lack of time, clinical workload, limited access to Internet and resources, knowledge and skills. One quarter of the respondents indicated that they teach EBHC. Perceived barriers to teaching EBHC reported related to students (e.g. lack of interest), context (e.g. access to databases) and educators (e.g. competing priorities). Respondents' suggestions for support included reliable Internet access, easy point-of-care access to databases and resources, increasing awareness of EBHC, building capacity to practice and facilitate learning of EBHC and a supportive community of practice. Educators play a critical role in facilitating EBHC learning not just in the classroom, but also in practice. Without adequate support, training and development, they are ill equipped to be the role models future healthcare professionals need.

Women who inject drugs (WWID) are neglected globally in research and programming yet may be likelier than males to practise sexual and injecting risks and be infected with HIV and more stigmatised but seek fewer services. Little is known about characteristics, practices and nexus between drugs and sex work of WWID in Vietnam, where unsafe injecting has driven HIV transmission, and commercial sex and inconsistent condom use are prevalent. This was the first quantitative investigation of Vietnamese WWID recruited as injecting drug users. This article summarises descriptive findings. A cross-sectional survey was conducted among WWID in Hanoi (n = 203) and Ho Chi Minh City (HCMC) (n = 200) recruited using respondent-driven sampling. Characteristics varied within and between sites. Twenty-two percent in Hanoi and 47.5 % in HCMC had never sold sex. Almost all commenced with smoking heroin, some as children. Most injected frequently, usually alone, although 8 % (Hanoi) and 18 % (HCMC) shared equipment in the previous month. Some had sex--and sold it--as children; most had multiple partners. Condom use was high with clients but very low with intimate partners, often injecting drug users. HIV knowledge was uneven, and large minorities were not tested recently (or ever) for HIV. Nearly all perceived intense gender-related stigma, especially for drug use. This ground-breaking study challenges assumptions about characteristics and risks based on anecdotal evidence and studies among men. Most WWID were vulnerable to sexual HIV transmission from intimate partners. Interventions should incorporate broader sociocultural context to protect this highly stigmatised population.

Human immunodeficiency virus (HIV) is spreading rapidly among men who have sex with men (MSM) in China. Anonymous questionnaires or direct interviews have been frequently used to study their behavior. The aim of the study was to describe the behavioral risk profile of the MSM in Beijing using the randomized response techniques (RRTs). A cross-sectional survey of sexual behavior among a sample of MSM was conducted in two HIV counseling and testing clinics in Beijing. The survey was carried out with an anonymous questionnaire containing sensitive questions on sexual behavior. To obtain the honest responses to the sensitive questions, three distinctive RRTs were used in the questionnaire: (1) Additive randomized response model for quantitative questions, (2) randomized response model for multiple choice questions, and (3) Simmons randomized response model for binomial questions. Formulae for the point estimate, variance, and confidence interval (CI) were provided for each specific model. Using RRTs in a sample of 659 participants, the mean age at first homosexual encounter was estimated to be 21.7 years (95% CI: 21.2-22.2), and each had sex with about three (2.9, 95% CI: 2.4-3.4) male partners on average in the past month. The estimated rate for consistent condom use was 56.4% (95% CI: 50.1-62.8%). In addition, condom was estimated to be used among 80.0% (95% CI: 74.1-85.9%) of the population during last anal sex with a male partner. Our study employed RRTs in a survey containing questions on sexual behavior among MSM, and the results showed that RRT might be a useful tool to obtain truthful feedback on sensitive information such as sexual behavior from the respondents, especially in traditional Chinese cultural settings.

Nurses' knowledge of pressure ulcer (PU) prevention and management is an important first step in the provision of optimal care. To evaluate PU prevention/risk, staging, and wound description knowledge, a descriptive, cross-sectional survey was conducted among nurses working in an acute care Turkish hospital. The survey instrument was a modified and translated version of the Pieper Pressure Ulcer Knowledge Test (PUKT), and its validity and reliability were established. Nurses completed a Personal Characteristics Form, including sociodemographic information and exposure to educational presentations and information about and experience with PUs, followed by the 49-item modified PUKT which includes 33 prevention/risk items, 9 staging items, and 7 wound description items. All items are true/false questions with an I don't know option (scoring: minimum 0, maximum 49). Correct answers received 1 point and incorrect/unknown answers received 0 points. The paper-pencil questionnaires were distributed by 2 researchers to all nurses in the participating hospital and completed by those willing to be included. Responses were analyzed using descriptive statistics. Pearson's correlation test was used to examine the relationship between quantitative variables, and mean scores were compared using the Mann-Whitney U and Kruskal-Wallis tests. Among the 308 participating nurses (mean age 29.5 ± 8.1 [range 19-56] years) most were women (257, 83.4%) with 7.3 ± 7.8 (range 1-36) years of experience. The mean knowledge score for the entire sample was 29.7 ± 6.7 (range 8-42). The overall percentage of correct answers was 60.6% to 61.8% for PU prevention/risk assessment, 60% for wound description, and 56.6% for PU staging. Knowledge scores were significantly (P <.05) higher for participants who attended at least 1 lecture/conference/course on PUs in the last year, read articles/books about PUs, cared for patients with PUs, or believed their patients were at risk for PU development.

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.

2017-04-01

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.

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.

Determinants of moral distress in daily nursing practice: a cross sectional correlational questionnaire survey.

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

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

Hypertension is an increasing problem in Southeast Asia, particularly in Bangladesh. Although some epidemiological studies on hypertension have been conducted in Bangladesh, the factors associated with hypertension in this nation remain unclear. We aimed to determine the factors associated with hypertension among the adults in Bangladesh. We conducted a cross-sectional study using data from the nationally representative 2011 Bangladesh Demographic and Health Survey (BDHS). A total of 7,839 (3,964 women and 3,875 men) adults aged 35 years and older who participated in the survey was included. Hypertension was defined by a systolic blood pressure ≥ 140 mmHg and/or, diastolic blood pressure ≥ 90 mmHg and/or, receipt of an anti-hypertensive medication at time of the survey. The degree of association between the risk factors and the outcome was assessed by the odd ratio (OR) obtained from the bivariate and multivariable logistic regression models. The overall prevalence of hypertension was 26.4 %, and the prevalence was higher in women (32.4%) than men (20.3%). Study participants with the age group of 60-69 years had higher odds of having hypertension (AOR: 3.77, 95% CI: 3.01-4.72) than the age group 35-39 years. Moreover, individuals who had higher educational attainment (AOR: 1.63, 95% C.I: 1.25-2.14) and higher wealth status (AOR = 1.91, 95% CI: 1.54-2.38) had higher odds of having hypertension than the individuals with no education and lower social status, respectively. The analysis also showed that high BMI (AOR: 2.19, 95% C.I: 1.87-2.57) and having diabetes (AOR: 1.54, 95% C.I: 1.31-1.83) were associated with the increasing risk of hypertension. Our study shows that the risk of hypertension was significantly associated with older age, sex, education, place of residence, working status, wealth index, BMI, and diabetes. Moreover, hypertension is largely untreated, especially in rural settings. The health system needs to develop appropriate strategies

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

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

The inelastic electron scattering cross section spectra of Fe have been calculated based on experimental spectra of characteristic reflection electron energy loss as dependences of the product of the inelastic mean free path by the differential inelastic electron scattering cross section on the electron energy loss. It has been shown that the inelastic electron scattering cross-section spectra have certain advantages over the electron energy loss spectra in the analysis of the interaction of electrons with substance. The peaks of energy loss in the spectra of characteristic electron energy loss and inelastic electron scattering cross sections have been determined from the integral and differential spectra. It has been shown that the energy of the bulk plasmon is practically independent of the energy of primary electrons in the characteristic electron energy loss spectra and monotonically increases with increasing energy of primary electrons in the inelastic electron scattering cross-section spectra. The variation in the maximum energy of the inelastic electron scattering cross-section spectra is caused by the redistribution of intensities over the peaks of losses due to various excitations. The inelastic electron scattering cross-section spectra have been analyzed using the decomposition of the spectra into peaks of the energy loss. This method has been used for the quantitative estimation of the contributions from different energy loss processes to the inelastic electron scattering cross-section spectra of Fe and for the determination of the nature of the energy loss peaks.

Extrinsic extinction cross-section in the multiple acoustic scattering by fluid particles

Mitri, F. G.

2017-04-01

Cross-sections (and their related energy efficiency factors) are physical parameters used in the quantitative analysis of different phenomena arising from the interaction of waves with a particle (or multiple particles). Earlier works with the acoustic scattering theory considered such quadratic (i.e., nonlinear) quantities for a single scatterer, although a few extended the formalism for a pair of scatterers but were limited to the scattering cross-section only. Therefore, the standard formalism applied to viscous particles is not suitable for the complete description of the cross-sections and energy balance of the multiple-particle system because both absorption and extinction phenomena arise during the multiple scattering process. Based upon the law of the conservation of energy, this work provides a complete comprehensive analysis for the extrinsic scattering, absorption, and extinction cross-sections (i.e., in the far-field) of a pair of viscous scatterers of arbitrary shape, immersed in a nonviscous isotropic fluid. A law of acoustic extinction taking into consideration interparticle effects in wave propagation is established, which constitutes a generalized form of the optical theorem in multiple scattering. Analytical expressions for the scattering, absorption, and extinction cross-sections are derived for plane progressive waves with arbitrary incidence. The mathematical expressions are formulated in partial-wave series expansions in cylindrical coordinates involving the angle of incidence, the addition theorem for the cylindrical wave functions, and the expansion coefficients of the scatterers. The analysis shows that the multiple scattering cross-section depends upon the expansion coefficients of both scatterers in addition to an interference factor that depends on the interparticle distance. However, the extinction cross-section depends on the expansion coefficients of the scatterer located in a particular system of coordinates, in addition to the

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.

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

Han, Yiyong; Tzoumas, Stratis; Nunes, Antonio

2015-09-15

Purpose: With recent advancement in hardware of optoacoustic imaging systems, highly detailed cross-sectional images may be acquired at a single laser shot, thus eliminating motion artifacts. Nonetheless, other sources of artifacts remain due to signal distortion or out-of-plane signals. The purpose of image reconstruction algorithms is to obtain the most accurate images from noisy, distorted projection data. Methods: In this paper, the authors use the model-based approach for acoustic inversion, combined with a sparsity-based inversion procedure. Specifically, a cost function is used that includes the L1 norm of the image in sparse representation and a total variation (TV) term. Themore » optimization problem is solved by a numerically efficient implementation of a nonlinear gradient descent algorithm. TV–L1 model-based inversion is tested in the cross section geometry for numerically generated data as well as for in vivo experimental data from an adult mouse. Results: In all cases, model-based TV–L1 inversion showed a better performance over the conventional Tikhonov regularization, TV inversion, and L1 inversion. In the numerical examples, the images reconstructed with TV–L1 inversion were quantitatively more similar to the originating images. In the experimental examples, TV–L1 inversion yielded sharper images and weaker streak artifact. Conclusions: The results herein show that TV–L1 inversion is capable of improving the quality of highly detailed, multiscale optoacoustic images obtained in vivo using cross-sectional imaging systems. As a result of its high fidelity, model-based TV–L1 inversion may be considered as the new standard for image reconstruction in cross-sectional imaging.« less

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

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.

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

DBCC Software as Database for Collisional Cross-Sections

2014-10-01

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.

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.

Assessment of livestock production constraints in the smallholder dairy systems in the western Kenya highlands was carried out using both qualitative and quantitative epidemiological methods. Rapid rural appraisals (qualitative) were conducted in rural and peri-urban areas. A cross-sectional survey (quantitative) was then conducted on a random sample of farms in the study area. Diseases, poor communication, lack of marketing of livestock produce, lack of artificial insemination services, and feed and water shortages during the dry season were identified as the major constraints to cattle production in both areas. Tick borne diseases (especially East Coast fever) were identified as the major constraint to cattle production. Qualitative methods were found to be more flexible and cheaper than the quantitative methods by a ratio of between 2.19-2.0. The two methods were found to complement each other. Qualitative studies could be applied in preliminary studies before initiating more specific follow up quantitative studies.

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

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.

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

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.

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.

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.

Absolute photoionization cross sections of furanic fuels: 2-ethylfuran, 2-acetylfuran and furfural.

Smith, Audrey R; Meloni, Giovanni

2015-11-01

Absolute photoionization cross sections of the molecules 2-ethylfuran, 2-acetylfuran and furfural, including partial ionization cross sections for the dissociative ionized fragments, are measured for the first time. These measurements are important because they allow fuel quantification via photoionization mass spectrometry and the development of quantitative kinetic modeling for the complex combustion of potential fuels. The experiments are carried out using synchrotron photoionization mass spectrometry with an orthogonal time-of-flight spectrometer used for mass analysis at the Advanced Light Source of Lawrence Berkeley National Laboratory. The CBS-QB3 calculations of adiabatic ionization energies and appearance energies agree well with the experimental results. Several bond dissociation energies are also derived and presented.

The 153Eu(n ,2 n ) m1,m2,g152Eu cross section was measured by means of the activation technique at three neutron energies in the range 13-15 MeV. The quasimonoenergetic neutron beam was formed via the 3H(d ,n ) 4He reaction, in the Pd-300 Neutron Generator at the Chinese Academy of Engineering Physics (CAEP). The activities induced in the reaction products were measured using high-resolution γ-ray spectroscopy. The cross section of the population of the second high-spin (8-) isomeric state was measured along with the reaction cross section populating both the ground (3-) and the first isomeric state (0-). Cross sections were also evaluated theoretically using the numerical code TALYS-1.8, with different level density options at neutron energies varying from the reaction threshold to 20 MeV. Results are discussed and compared with the corresponding literature.

The association between student characteristics and depression among students attending women's colleges (single-sex institutions of higher education that exclude or limit males from admission) is poorly understood. Our objective was to estimate the prevalence of depression and determine behavioral and social characteristics associated with depression among students attending a women's college. We administered a cross-sectional Internet-based survey between April and May 2012 to students (n = 277) enrolled at a private women's college in the southeastern US. Center for Epidemiologic Studies Depression (CES-D) and Depression Anxiety Stress Scale 21 (DASS-21) instruments measured self-reported depression. Bivariate and multivariable logistic regression methods were used to estimate adjusted associations. Prevalence of depression measured by CES-D and DASS-21 instruments was 26.3% (95% confidence interval [CI] 20.8-32.3%) and 26.0% (95% CI 20.4-32.3%), respectively. After adjusting for confounders, absence of strong social support (prevalence odds ratio [OR] = 4.3, 95% CI 1.4-13.7), history of mental health disorder (OR = 4.8 95% CI 1.9-12.4), and poor sleep hygiene (OR = 2.8, 95% CI 1.3-5.8) were associated with depression. This cross-sectional survey identified absence of strong social support, history of mental health disorder, and poor sleep hygiene as potential predictors of depression among students attending a women's college. Further investigation of these factors may inform depression interventions for students attending women's colleges and other undergraduate student populations.

Cross sections are measured, relative to a reference 93Nb(n,2n)92mNb reaction cross section, by means of the activation technique at three neutron energies 13.5, 14.1, and 14.8 MeV. Monoenergetic neutron beams were formed via the 3H(d,n)4He reaction and both Eu2O3 samples and Nb monitor foils were activated together to determine the reaction cross section and the incident neutron flux. The activities induced in the reaction products were measured using high-resolution gamma ray spectroscopy. Cross sections were also evaluated theoretically using the numerical nuclear model code, TALYS-1.8 with different level density options at neutron energies varying from the reaction threshold to 20 MeV. Results are discussed and compared with the corresponding literature.

We measured neutron-induced reaction cross sections for the 76Ge(n,2n)75m,gGe reactions and their isomeric cross section ratios σm/σg at three neutron energies between 13 and 15MeV by an activation and off-line γ-ray spectrometric technique using the K-400 Neutron Generator at the Chinese Academy of Engineering Physics (CAEP). Ge samples and Nb monitor foils were activated together to determine the reaction cross section and the incident neutron flux. The monoenergetic neutron beams were formed via the 3H( d, n)4He reaction. The pure cross section of the ground state was derived from the absolute cross section of the metastable state and the residual nuclear decay analysis. The cross sections were also calculated using the nuclear model code TALYS-1.8 with different level density options at neutron energies varying from the reaction threshold to 20MeV. Results are discussed and compared with the corresponding literature data.

We investigated contemporary diabetes care, quality of glycaemic control, and progression of obesity in patients with diabetes mellitus in different cultural regions within Switzerland. Overall, 1121 patients treated for type 2 diabetes mellitus by 134 general practitioners were enrolled in this representative, national, cross-sectional survey and were followed retrospectively from the start of diabetes treatment. Patients were classified into four cultural regions; the German, French, Italian and Romansh speaking parts of Switzerland. During 5.5 ± 5.1 years of diabetes treatment (retrospective survey), mean HbA1c decreased from 8.28 ± 2.01% to 7.03 ± 1.24%, fasting glucose decreased from 9.97 ± 3.86 to 7.52 ± 2.23 mmol/l, and BMI decreased from 30.2 ± 5.5 to 29.8 ± 5.6 kg/m² (p <0.001 for all parameters). Insulin therapy was associated with a larger improvement of mean HbA1c (-1.66 ± 2.33% vs. -1.15 ± 1.91%, p = 0.001) and an increase in BMI (+0.36 ± 2.92 vs. -0.63 ± 2.60 kg/m2, p <0.001). At the time when the cross-sectional survey was conducted, the mean HbA1c and fasting glucose were higher in the Italian part compared to other regions (7.72 ± 1.60% and 9.03 ± 2.49 mmol/l, respectively, p <0.001), and lower in the German part (6.89 ± 1.02% and 7.25 ± 2.02 mmol/l, respectively, p <0.001). In comparison to other regions, biguanides were more often used in the French part (86.1% versus 75.7%), insulin secretagogues in the Italian part (69.9% versus 37.8%), thiazolidinediones in the Romansh part (34.1% versus 17.8%), and insulin was more often used in the German part of Switzerland (27.0% versus 17.1%) (p <0.01 for all parameters). Efforts to identify regional-cultural differences and attempts to overcome associated potential barriers should be emphasised in any health care system when aiming for better diabetic patient care.

ABSTRACT Aim: Medical student educators play critical roles in evidence-based healthcare (EBHC) teaching and learning and as role models practicing EBHC. This study assessed their confidence to practice and teach EBHC, their attitude to EBHC and barriers to practicing and teaching EBHC. Methods: We conducted a cross-sectional online survey of educators of undergraduate medical students at a South African academic institution. STATA 12 was used for quantitative data analysis. Responses to open-ended questions were coded, and further interpretation done using thematic content analysis. Results: Forty two (19%) educators from various departments responded to the invitation sent to everyone formally involved in teaching undergraduate medical students. They had high levels of knowledge and understanding of EBHC. Many had received training in teaching and learning approaches, although EBHC training received was mainly on enabling competencies. Limitations to practicing EBHC included lack of time, clinical workload, limited access to Internet and resources, knowledge and skills. One quarter of the respondents indicated that they teach EBHC. Perceived barriers to teaching EBHC reported related to students (e.g. lack of interest), context (e.g. access to databases) and educators (e.g. competing priorities). Respondents’ suggestions for support included reliable Internet access, easy point-of-care access to databases and resources, increasing awareness of EBHC, building capacity to practice and facilitate learning of EBHC and a supportive community of practice. Conclusion: Educators play a critical role in facilitating EBHC learning not just in the classroom, but also in practice. Without adequate support, training and development, they are ill equipped to be the role models future healthcare professionals need. PMID:26626283

Published electron impact cross section data on halogens Cl2, F2, and halogen containing compounds such as Cx Fy, HCl, Cx Cly Fz are reviewed and critically evaluated based on the information provided by various researchers. The present work reports data on electron impact excitation, ionization, dissociation, electron attachment, electron detachment, and photo detachment. Elastic scattering cross sections and data on bulk properties such as diffusion coefficients in various background gases are also evaluated. Since some of the cross sectional data is derived from indirect measurements such as drift velocity, care has been taken to reconcile the differences among the reported data with due attention to the measurement technique. In conclusion, the processes with no or very limited amount of data and questionable set of data are identified and recommendation for further research direction is made.

Longitudinal studies of women's health often seek to identify predictors of good health. Research has shown that following simple guidelines can halve women's mortality. The ongoing Australian Longitudinal Study of Women's Health (ALSWH) shows that Australian women are getting better at reducing their smoking and alcohol use, and are generally diligent about attending recommended health screenings, but are becoming less successful at dealing with obesity. There are communities of women who live unusually healthy lives (Rosetans, Seventh-Day Adventists, traditional Japanese women), but their lifestyles are unlikely to be adopted widely. Universal Medicine (UM) is a complementary-to-medicine approach that emphasizes personal empowerment and the importance of menstrual health symptoms. This survey investigates whether the approximately 500 women associated with UM exhibit health status significantly above the norm. As part of this investigation, questions for a newly developed menstrual attitudes questionnaire will also be evaluated. A quantitative cross-sectional survey of women in a UM cohort was designed with the help of three focus groups of women at three life stages: in menses, peri-menopausal, and menopausal. The menstrual attitudes portion of the survey incorporates the insights of these women regarding female health issues. The survey also includes 41 questions taken from the ALSWH. Focus groups generated additional questions about symptoms experienced and attitudes toward female health issues. ALSWH questions, including a range of health scales like the Short Form 36 (SF-36), Center for Epidemiologic Studies Depression Scale, Perceived Control Scale, Kessler Psychological Distress Scale, and the Multi-Item Summed Score for Perceived Stress, along with questions about experienced major health events, were investigated and incorporated if considered suitable. The validity of the menstrual attitudes questionnaire will be evaluated with Cohen's kappa. ALSWH

Using linearly-polarized laser-Compton scattering γ-rays, partial E1 and M1 photoneutron cross sections along with total cross sections were determined for 207,208Pb at four energies near neutron threshold by measuring anisotropies in photoneutron emission. Separately, total photoneutron cross sections were measured for 207,208Pb with a high-efficiency 4π neutron detector. The partial cross section measurement provides direct evidence for the presence of pygmy dipole resonance (PDR) in 207,208Pb in the vicinity of neutron threshold. The strength of PDR amounts to 0.32%-0.42% of the Thomas-Reiche-Kuhn sum rule. Several μN2 units of B(M1)↑ strength were observed in 207,208Pb just above neutron threshold, which correspond to M1 cross sections less than 10% of the total photoneutron cross sections.

Calculation of total electron excitation cross-sections and partial electron ionization cross-sections for the elements. Ph.D. Thesis

Computer programs were used to calculate the total electron excitation cross-section for atoms and the partial ionization cross-section. The approximations to the scattering amplitude used are as follows: (1) Born, Bethe, and Modified Bethe for non-exchange excitation; (2) Ochkur for exchange excitation; and (3) Coulomb-Born of non-exchange ionization. The amplitudes are related to the differential cross-sections which are integrated to give the total excitation (or partial ionization) cross-section for the collision. The atomic wave functions used are Hartree-Fock-Slater functions for bound states and the coulomb wave function for the continuum. The programs are presented and the results are examined.

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.

2003-01-01

Objectives: To establish the prevalence and distribution of witnesses, victims, and perpetrators of different types of violence in the general population and the proportion of victims consulting health services or reporting the incident to authorities. Methods: Cross sectional survey of a random sample of 3007 inhabitants between the ages of 15 and 60 in the city of Bogotá, Colombia, in 1997, based on a face to face interview. Results: Age adjusted past year prevalence of witnesses, victims, and perpetrators of physical aggression was 61%, 27%, and 27%, respectively, while lifetime prevalence of witnesses, victims, and perpetrators of assault with a weapon in this population reached 70%, 55%, and 5.8%. Between 11% and 67% of the victims consulted a health service and less than 32% reported the incident to an authority. Those involved in most types of physical violence tended to be young, male, from lower middle social classes, with some degree of secondary education, and single or divorced. Conclusions: Prevalence of witnesses and victims of violence in this sample appears to be high, while perpetrators constitute a small proportion. Violence is not equally distributed throughout the population suggesting the possibility of identifying a population at higher risk for the development of intervention programmes. PMID:12700220

Temperature dependence of the cross section for the fragmentation of thymine via dissociative electron attachment

Kopyra, Janina; Abdoul-Carime, Hassan, E-mail: hcarime@ipnl.in2p3.fr

Providing experimental values for absolute Dissociative Electron Attachment (DEA) cross sections for nucleobases at realistic biological conditions is a considerable challenge. In this work, we provide the temperature dependence of the cross section, σ, of the dehydrogenated thymine anion (T − H){sup −} produced via DEA. Within the 393-443 K temperature range, it is observed that σ varies by one order of magnitude. By extrapolating to a temperature of 313 K, the relative DEA cross section for the production of the dehydrogenated thymine anion at an incident energy of 1 eV decreases by 2 orders of magnitude and the absolutemore » value reaches approximately 6 × 10{sup −19} cm{sup 2}. These quantitative measurements provide a benchmark for theoretical prediction and also a contribution to a more accurate description of the effects of ionizing radiation on molecular medium.« less

Most patients experience changes to prescribed medicines during a hospital stay. Ensuring they understand such changes is important for preventing adverse events post-discharge and optimising patient understanding. However, little work has explored the information that patients receive about medicines or their perceived needs for information and support after discharge. To determine information that hospital inpatients who experience medicine changes receive about their medicines during admission and their needs and preferences for, and use of, post-discharge support. Cross-sectional survey with adult medical inpatients experiencing medicine changes in six English hospitals, with telephone follow-up 2-3 weeks post-discharge. A total of 444 inpatients completed surveys, and 99 of these were followed up post-discharge. Of the 444, 44 (10%) were unaware of changes to medicines and 65 (16%) did not recall discussing them with a health professional, but 305 (77%) reported understanding the changes. Type of information provided and patients' perceived need for post-discharge support differed between hospitals. Information about changes was most frequently provided by consultant medical staff (157; 39%) with pharmacists providing information least often (71; 17%). One third of patients surveyed considered community pharmacists as potential sources of information about medicines and associated support post-discharge. Post-discharge, just 5% had spoken to a pharmacist, although 35% reported medicine-related problems. In north-west England, patient inclusion in treatment decisions could be improved, but provision of information prior to discharge is reasonable. There is scope to develop hospital and community pharmacists' role in medicine optimisation to maximise safety and effectiveness of care. © 2017 Royal Pharmaceutical Society.

Estimates of the proportion of HIV infections coming from within regular sexual relationships among gay and bisexual men (GBM) vary widely. Research surveys use various partner type categories, but there is little understanding of how men classify their partners. We conducted an online cross-sectional survey of Australian GBM exploring sexual relationships, including 2057 men reporting on 2566 regular partnerships. Just over half of the partnerships were considered 'relationships', while the remainder were non-romantic 'fuckbuddy'-style arrangements. In multivariable analysis, factors associated with considering the partnership a 'relationship' were: using a 'romantic' descriptor, partnership length, monogamous agreements, any condomless anal sex with each other, love, and commitment. The category of 'regular partner' can mask diverse partnership types, which have different meanings to GBM, associated behaviours, and HIV risks. Certain HIV prevention techniques may be more suited to particular types of partnerships. 'Fuckbuddy' arrangements need to be more explicitly acknowledged in HIV prevention.

The 56Fe cross section we are interested in have a lot of fluctuations. We would like to fit the average of the cross section with cross sections calculated within EMPIRE. EMPIRE is a Hauser-Feshbach theory based nuclear reaction code, requires cross sections to be smoothed using a Lorentzian profile. The plan is to fit EMPIRE to these cross sections in the fast region (say above 500 keV).

Gok Metin, Zehra; Izgu, Nur; Karadas, Canan; Arikan Donmez, Ayse

In Turkey, between 22.1% and 84.1% of patients with cancer use complementary and alternative medicine (CAM). However, few CAM-related studies have focused on the perspective of oncology nurses. This study aimed to determine the knowledge, attitudes, and practices of Turkish oncology nurses regarding CAM. A descriptive cross-sectional survey of 127 participants was conducted in Ankara, Turkey. A semistructured questionnaire including characteristics, knowledge, attitudes, and practices of oncology nurses toward CAM was administered to participants. We found that more than half of nurses (54.0%) surveyed had no information on CAM modalities. Most oncology nurses (81.1%) used audiovisual media sources to obtain CAM information. Many nurses (81.3%) reported not using any CAM in cancer care, and only 26.8% recommended CAM to patients. Most nurses used CAM to accelerate wound healing (19.7%) and to manage symptoms, including constipation and diarrhea (8.8%) and anxiety (7.9%). Music (52.8%), massage (49.6%), and exercise (48.8%) were stated to be beneficial. Important barriers to use CAM for patients with cancer involved a lack of knowledge (60.6%); needing physician approval to apply any CAM methods to patients (52.1%); legal and institutional issues (47.2%); and limited educational, training, or certificate programs (44.1%). There is a need for increased knowledge about CAM by oncology nurses, considering their vital role in symptom management of patients with cancer. This can be achieved through solving legal and institutional problems, structured and comprehensive education/training programs, and the integration of CAM therapy into cancer care guidelines.

Predictors of hospital nurses' intent to stay: a cross-sectional questionnaire survey in Shanghai, China.

To investigate predictors of hospital nurses' intent to stay in the nursing profession. A cross-sectional survey design was adopted. Over 1000 nurses working in hospitals in Shanghai, China, were invited to complete a survey questionnaire between May and October 2009 and 919 nurses responded for an 82% response rate. Regression models explained 41.3% of variance in nurse intent to stay. Although the proposed model hypothesized 18 predictors of intent to stay, only seven were statistically significant factors of nurse intent to stay: normative commitment, economic costs commitment, age, limited alternatives commitment, praise/recognition, professional advancement opportunities and the hospital classification. Of these, the strongest predictors were normative commitment, economic costs commitment and age, which explained 37.3% of variance in nurse intent to stay. Possible strategies to improve nurses' intent to stay include employment practices that improve the work environment, increased wages and benefits, and greater professional opportunity for nurses' personal growth development and promotion. Healthcare organizations should establish an asserting and nurturing environment for nurses and improve nurses' normative commitment and economic costs commitment. Increased effort should be made to improve nurses' conditions in primary and secondary hospitals where nurses report a lower level of intent to stay in nursing. Participants came from a limited number of hospitals in Shanghai. A larger sample from different hospitals in Shanghai and other districts in Mainland China could have enhanced the generalizability of the results and increased the power of the study. © 2012 The Authors.

Objectives To explore the prevalence of attitudes and beliefs about back pain in New Zealand and compare certain beliefs based on back pain history or health professional exposure. Design Population-based cross-sectional survey. Setting Postal survey. Participants New Zealand residents and citizens aged 18 years and above. 1000 participants were randomly selected from the New Zealand Electoral Roll. Participants listed on the Electoral Roll with an overseas postal address were excluded. 602 valid responses were received. Measures Attitudes and beliefs about back pain were measured with the Back Pain Attitudes Questionnaire (Back-PAQ). The interaction between attitudes and beliefs and (1) back pain experience and (2) health professional exposure was investigated. Results The lifetime prevalence of back pain was reported as 87% (95% CI 84% to 90%), and the point prevalence as 27% (95% CI 24% to 31%). Negative views about the back and back pain were prevalent, in particular the need to protect the back to prevent injury. People with current back pain had more negative overall scores, particularly related to back pain prognosis. There was uncertainty about links between pain and injury and appropriate physical activity levels during an episode of back pain. Respondents had more positive views about activity if they had consulted a health professional about back pain. The beliefs of New Zealanders appeared to be broadly similar to those of other Western populations. Conclusions A large proportion of respondents believed that they needed to protect their back to prevent injury; we theorise that this belief may result in reduced confidence to use the back and contribute to fear avoidance. Uncertainty regarding what is a safe level of activity during an episode of back pain may limit participation. People experiencing back pain may benefit from more targeted information about the positive prognosis. The provision of clear guidance about levels of activity may enable

The satisfaction in career is an important indicator for the growth of the discipline and the profession. An empirical investigation of satisfaction in career and amendments needed in course and profession may help in growth of discipline. To assess career satisfaction among Dental Public Health (DPH) specialists working in India and analyze their perspective on changes required in the profession. Questionnaire for this cross-sectional survey was adapted from Minnesota Job Satisfaction Survey which included 40 enquiries to understand the reasons for choosing public health dentistry as career, competencies of public health dentists, satisfaction as a public health dentist and changes required in the profession. The questions were both open and closed end type. Updated electronic mail details of all registered public health dentists were collected from the head office of Indian Association of Public Health Dentistry. Each participant was contacted by electronic mail and consent to participate were sought. Reminders were e-mailed thrice during three months. A total of 580 participants were contacted. A total of 183 responses were received, among which 179 consented. Nearly half of the respondents felt they are yet to achieve the accomplishment from the present career as public health dentist. Only 46.9% felt that there is advancement in the profession as career. Nearly three-fourth of respondents could not attain recognition as a public health dentist. A 45.8% of respondents were of the opinion that career in public health dentistry would provide them a steady employment and 53.1% of public health dentists would envision as satisfied in their career in next 10 years. Nearly 85% felt public health dentistry training needs a major course correction. There has been some reservation or skepticism about the future of the specialty as the jobs are in declining stage. This information provides insight about success and failures of public health dentistry as profession which

Patients can play an important role in reducing healthcare harm but little is known about the factors that may affect patients' willingness to participate. In order to encourage the 'active' patient it is critical that we gain a deeper understanding of the antecedents of safety-relevant behaviours. Doing this will enable the implementation of effective interventions aimed at supporting patients to work with healthcare professionals in ensuring safe care. To examine predictors of patients' intentions to engage in two safety behaviours: (1) reminding healthcare staff to wash their hands and; (2) notifying healthcare staff if they are not wearing a hospital identification bracelet. Cross-sectional survey study. A purposive sampling method was employed to recruit 80 medical and surgical hospital inpatients aged 18-80 (mean 48) from one inner city London teaching hospital. A 42 item survey that measured the extent that patients' control beliefs, behavioural beliefs, normative beliefs and perceived susceptibility and severity towards a hospital-acquired infection or a misidentification error could predict their intentions to ask doctors/nurses about their hand washing compliance or notify doctors/nurses if they are not wearing a hospital identification bracelet. Data was analysed using multiple regression analysis. Control beliefs, normative beliefs and perceived severity were the strongest predictors of patients' intentions to participate in both behaviours. The regression models accounted for a smaller percentage of the variance in patients' intentions to ask doctors/nurses if they have washed their hands (42%/37%) than notifying staff if they were not wearing an identification bracelet (54%/56%). If patients understand why a behaviour is beneficial, they perceive it as acceptable to participate in and that they have control over the decision to engage in the behaviour, we hypothesise that more patients will intend to participate in that behaviour.

We report a detailed calculation of total elastic, differential elastic, momentum transfer and electronic excitation for electron impact on difluoroacetylene (C2F2) molecules using the R-matrix method at low energies. After testing many target models, the final results are reported for the target model that gave the best target properties and predicted the lowest value of the shape resonance. The shape resonance is detected at 5.86 eV and 6.49 eV with the close-coupling and static exchange models due to 2Πg (2B2g, 2B3g) states. We observed that the effect of polarization becomes prominent at low energies below 4 eV, decreasing the magnitude of the elastic cross section systematically as it increases for C2F2. We have also computed elastic cross sections for C2H2, C2F4 and C2H4 with a similar model and compared with the experimental data for these molecules along with C2F2. General agreement is found in terms of the shape and nature of the cross section. Such a comparison shows the reliability of the present method for obtaining the cross section for C2F2. The calculation of elastic scattering cross section is extended to higher energies up to 5 keV using the spherical complex optical potential method. The two methods are found to be consistent, merging at around 12 eV for the elastic scattering cross section. Finally we report the total ionization cross section using the binary encounter Bethe method for C2F2. The perfluorination effect in the shape and magnitude of the elastic, momentum transfer and ionization cross sections when compared with C2H2 showed a similar trend to that in the C2H4-C2F4 and C6H6-C6F6 systems. The cross-section data reported in this article could be an important input for the development of a C2F2 plasma model for selective etching of Si/SiO2 in the semiconductor industry.

To assess the predictors of intentions to quit smoking in a community sample of Aboriginal smokers of reproductive age, in whom smoking prevalence is slow to decline. A cross-sectional survey involved 121 Aboriginal smokers, aged 18-45 years from January to May 2014, interviewed at community events on the Mid-North Coast NSW. Qualitative and quantitative data were collected on smoking and quitting attitudes, behaviours and home smoking rules. Perceived efficacy for quitting, and perceived threat from smoking, were uniquely assessed with a validated Risk Behaviour Diagnosis (RBD) Scale. Logistic regression explored the impact of perceived efficacy, perceived threat and consulting previously with a doctor or health professional (HP) on self-reported intentions to quit smoking, controlling for potential confounders, that is, protection responses and fear control responses, home smoking rules, gender and age. Participants' comments regarding smoking and quitting were investigated via inductive analysis, with the assistance of Aboriginal researchers. Two-thirds of smokers intended to quit within 3 months. Perceived efficacy (OR=4.8; 95% CI 1.78 to 12.93) and consulting previously with a doctor/HP about quitting (OR=3.82; 95% CI 1.43 to 10.2) were significant predictors of intentions to quit. 'Smoking is not doing harm right now' was inversely associated with quit intentions (OR=0.25; 95% CI 0.08 to 0.8). Among those who reported making a quit attempt, after consulting with a doctor/HP, 40% (22/60) rated the professional support received as low (0-2/10). Qualitative themes were: the negatives of smoking (ie, disgust, regret, dependence and stigma), health effects and awareness, quitting, denial, 'smoking helps me cope' and social aspects of smoking. Perceived efficacy and consulting with a doctor/HP about quitting may be important predictors of intentions to quit smoking in Aboriginal smokers of reproductive age. Professional support was generally perceived to be low

Exercise training is a core component of cardiac rehabilitation (CR), however, little information exists regarding the specific exercise interventions currently provided for coronary heart disease in Australian practice. We aimed to analyse the current status of exercise-based CR services across Australia. Cross-sectional survey. Australian sites offering exercise-based CR were identified from publically available directories. All sites were invited by email to participate in an online Survey Monkey questionnaire between October 2014 and March 2015, with reminders via email and phone follow-up. Questions investigated the demographics and format of individual programmes, as well as specific exercise training characteristics. 297 eligible programmes were identified, with an 82% response rate. Most sites (82%) were based at hospital or outpatient centres, with home (15%), community (18%) or gym-based options (5%) less common. While CR was most often offered in a comprehensive format (72% of sites), the level of exercise intervention varied greatly among programmes. Most frequently, exercise was prescribed 1-2 times per week for 60 min over 7 weeks. Almost one-quarter (24%) had a sole practitioner supervising exercise, although the majority used a nurse/physiotherapist combination. Low to moderate exercise intensities were used in 60% of programmes, however, higher intensity prescriptions were not uncommon. Few sites (<6%) made use of technology, such as mobile phones or the internet, to deliver or support exercise training. While advances have been made towards providing flexible and accessible exercise-based CR, much of Australia's service remains within traditional models of care. A continuing focus on service improvement and evidence-based care should, therefore, be considered a core aim of those providing exercise for CR in order to improve health service delivery and optimise outcomes for patients.

Objective We aimed to determine the prevalence of violence directed at emergency department (ED) physicians in Turkey and confirm the factors influencing such violence. Design Cross-sectional survey study. Setting Country of Turkey. Participants Physicians currently practising in EDs in Turkey. Main outcome measures 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. Results 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. Conclusions 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. PMID:28663323

To measure the prevalence of domestic violence (DV) experienced by women seeking termination of pregnancy (TOP) in a UK abortion clinic. A cross-sectional anonymous questionnaire survey of all women aged over 16 years accessing a TOP clinic in inner London between 20 May 2012 and 2 July 2012. The main outcome measures were: distribution of questionnaires, response rate, lifetime prevalence of abuse, past-year prevalence of physical and sexual abuse, prevalence of physical abuse during current pregnancy, relationship of lifetime abuse to number of terminations, and receptivity to DV services. Questionnaires were distributed to 46% (383/828) of women accessing the clinic. Response rate was 50% (190/383). Lifetime prevalence of abuse was 16%. Past-year prevalence of physical abuse was 11% and sexual abuse was 4%. Prevalence of physical abuse during the current pregnancy was 4%. Prevalence of lifetime abuse was lower in women having a first termination (12%) versus one (20%) or two or more previous terminations (24%), although this was not statistically significant (p=0.192). The majority (75%) of participants expressing an opinion on the possibility of having a support service for DV in the abortion clinic setting were positive, unrelated to their personal experience, but some concerns were raised about implementation. In order to provide effective support for women, services require a needs assessment of their local population. Asking women presenting for abortion about DV, even anonymously, is challenging but feasible. Future work should be directed to women's unmet safety needs.

Docter, R F; Prince, V

1997-12-01

One thousand and thirty-two male periodic cross-dressers (transvestites) responded to an anonymous survey patterned after Prince and Bentler's (1972) report. With few exceptions, the findings are closely related to the 1972 survey results. Eighty-seven percent described themselves as heterosexual. All except 17% had married and 60% were married at the time of this survey. Topics surveyed included demographic, childhood, and family variables, sexual orientation and sexual behavior, cross-gender identity, cross-gender role behavior, future plans to live entirely as a woman, and utilization of counseling or mental health services. Of the present sample, 45% reported seeking counseling compared to 24% of the 1972 survey, and those reporting strong transsexual inclinations were up by 5%. Today's transvestites strongly prefer both their masculine and feminine selves equally. A second research objective was to identify variables discriminating between so-called Nuclear (stable, periodic cross-dressers) and Marginal transvestites (more transgendered or transsexually inclined); 10 strongly discriminating parameters were found. The most important are (i) cross-gender identity, (ii) commitment to live entirely as a woman, (iii) taking steps toward body feminization, (iv) low sexual arousal to cross-dressing. Neither age nor experience as a cross-dresser were found to be correlates of cross-gender identity. Although the present generation of transvestites describe themselves much as did similar subjects 20 years ago, the percentage migrating toward full-time living as a woman is greater.

Structured Abstract Objectives We describe the methodology for a major study investigating the impact of reconfigured cleft care in the United Kingdom (UK) 15 years after an initial survey, detailed in the Clinical Standards Advisory Group (CSAG) report in 1998, had informed government recommendations on centralization. Setting and Sample Population This is a UK multicentre cross-sectional study of 5-year-olds born with non-syndromic unilateral cleft lip and palate. Children born between 1 April 2005 and 31 March 2007 were seen in cleft centre audit clinics. Materials and Methods Consent was obtained for the collection of routine clinical measures (speech recordings, hearing, photographs, models, oral health, psychosocial factors) and anthropometric measures (height, weight, head circumference). The methodology for each clinical measure followed those of the earlier survey as closely as possible. Results We identified 359 eligible children and recruited 268 (74.7%) to the study. Eleven separate records for each child were collected at the audit clinics. In total, 2666 (90.4%) were collected from a potential 2948 records. The response rates for the self-reported questionnaires, completed at home, were 52.6% for the Health and Lifestyle Questionnaire and 52.2% for the Satisfaction with Service Questionnaire. Conclusions Response rates and measures were similar to those achieved in the previous survey. There are practical, administrative and methodological challenges in repeating cross-sectional surveys 15 years apart and producing comparable data. PMID:26567851

Dural sinuses vary in size and shape in many pathological conditions with abnormal intracranial pressure. Size and shape normograms of dural brain sinuses are not available. The creation of such normograms may enable computer-assisted comparison to pathologic exams and facilitate diagnoses. The purpose of this study was to quantitatively evaluate normal magnetic resonance venography (MRV) studies in order to create normograms of dural sinuses using a computerized algorithm for vessel cross-sectional analysis. This was a retrospective analysis of MRV studies of 30 healthy persons. Data were analyzed using a specially developed Matlab algorithm for vessel cross-sectional analysis. The cross-sectional area and shape measurements were evaluated to create normograms. Mean cross-sectional size was 53.27±13.31 for the right transverse sinus (TS), 46.87+12.57 for the left TS (p=0.089) and 36.65+12.38 for the superior sagittal sinus. Normograms were created. The distribution of cross-sectional areas along the vessels showed distinct patterns and a parallel course for the median, 25th, 50th and 75th percentiles. In conclusion, using a novel computerized method for vessel cross-sectional analysis we were able to quantitatively characterize dural sinuses of healthy persons and create normograms.

To obtain a comprehensive understanding of the job opinions of hospital professionals by conducting qualitative analyses of the open comments included in a job satisfaction survey and combining these results with the quantitative results. A cross-sectional survey targeting all Lausanne University Hospital professionals was performed in the fall of 2013. The survey considered ten job satisfaction dimensions (e.g. self-fulfilment, workload, management, work-related burnout, organisational commitment, intent to stay) and included an open comment section. Computer-assisted qualitative analyses were conducted on these comments. Satisfaction rates on the included dimensions and professional groups were entered as predictive variables in the qualitative analyses. Of 10 838 hospital professionals, 4978 participated in the survey and 1067 provided open comments. Data from 1045 respondents with usable comments constituted the analytic sample (133 physicians, 393 nurses, 135 laboratory technicians, 247 administrative staff, including researchers, 67 logistic staff, 44 psycho-social workers, and 26 unspecified). Almost a third of the comments addressed scheduling issues, mostly related to problems and exhaustion linked to shifts, work-life balance, and difficulties with colleagues' absences and the consequences for quality of care and patient safety. The other two-thirds related to classic themes included in job satisfaction surveys. Although some comments were provided equally by all professional groups, others were group specific: work and hierarchy pressures for physicians, healthcare quality and patient safety for nurses, skill recognition for administrative staff. Overall, respondents' comments were consistent with their job satisfaction ratings. Open comment analysis provides a comprehensive understanding of hospital professionals' job experiences, allowing better consideration of quality initiatives that match the needs of professionals with reality.

There continue to be assumptions within the nursing literature that nursing is synonymous with a feminine sex role identity. A comparative cross-sectional survey consisting of the Bem Sex Role Inventory and the Australian sex role scale was used to determine sex difference in gender characteristics of Australian nurses and with male engineers. A statistically significant difference in femininity was found between all the samples (F((2,908)) = 20.24, p < 0.00001; F((2,908)) = 60.13, p < 0.00001). A statistical difference in masculinity was found between female nurses and the two male samples on the two masculine scales (F((2,908)) = 12.48, p < 0.000001; F((2,908)) = 6.94, p = 0.001). Path analysis found strong significant direct relationships between the samples and expressive orientation (t = 27.67) and self display (t = 12.42). Whilst differences in expressive characteristics were found between male and female nurses, a similar difference was found between male nurses and male engineers, supporting the notion that male nurses perceive themselves as having feminine characteristics essentially required for nursing.

Calculated fusion-evaporation cross sections from five different codes are compared to experimental data. The present comparison extents over a large range of nuclei and isotopic chains to investigate the evolution of experimental and calculated cross sections. All models more or less overestimate the experimental cross sections. We found reasonable agreement by using the geometrical average of the five model calculations and dividing the average by a factor of 11.2. More refined analyses are made for example for the 100Sn region.

Gestational diabetes mellitus (GDM) is one of the most common pregnancy disorders; however, if well managed, women with GDM experience similar pregnancy outcomes to those without. Currently, there is limited evidence on actual management practices across Australia or how multidisciplinary teams interact to optimise care. To examine the current screening, diagnostic, task and role perceptions and management practices, as reported by members of the GDM multidisciplinary team. A 64-item electronic survey containing multiple choice, Likert scale and open-ended questions was developed for this cross-sectional observational study and advertised through health professional organisations and Queensland Health facilities in May and June, 2017. The 183 survey respondents included 45 diabetes educators, 43 dietitians, 21 endocrinologists/diabetes specialists, 14 obstetricians and 21 midwives. Although almost 90% reported using updated diagnostic guidelines, less than two-thirds used GDM management guidelines. While 68% reported using the same blood glucose targets for GDM management, there was variation to what criteria prompted the commencement of medication to control blood glucose levels. There was a good consensus concerning the health professional responsible for tasks such as medical nutrition therapy, gestational weight gain and self-blood glucose monitoring education and ultrasound use. Other tasks appeared to be the role of almost any member of the GDM multidisciplinary team. The survey results indicate there is a need for consistent evidence on how to best manage GDM and that role identity, access to specialist knowledge and best practice need to be clearly defined within GDM models of care. © 2018 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

AIM.: This study focuses on the experience of healthcare staff with regard to patient and visitor violence in a general hospital. The occurrence of patient and visitor violence, staffs' interventions and the consequences of violence for different professions are investigated. There is a lack of studies describing the factors influencing the occurrence of patient and visitor violence, intervention strategies and consequences. Existing studies often focus on nurses' experiences and single interactive factors between staff and patients/visitors involved. A cross-sectional survey. The survey was conducted in 2007 including 2495 staff working on different wards in a Swiss university general hospital. The questionnaire used was the Survey of Violence Experienced by Staff German Version-Revised. Half of the staff experienced patient and visitor violence in the past 12 months and 11% in the past week. The age of the staff and the length of experience in their present workplace influenced the exposure to patient and visitor violence. Violence occurred mainly when staff carried out tasks involving close personal contact. Only 16% of the staff was trained in aggression management. The feeling of confidence in managing patient and visitor violence depended significantly on the organizational attitude towards violence. The principal interventions used were calming and informative discussion. To prevent patient and visitor violence and improve management strategies, training which focuses on communication skills, which is specific to the professional context and which emphasizes patient centeredness, need to be designed and implemented. A strong organizational commitment is imperative to reduce violence. © 2012 Blackwell Publishing Ltd.

Early detection and intervention seem to improve development in autistic children, and teachers form an important part of their early social environment. The objective of this study was to assess baseline knowledge and misconceptions regarding autism among school teachers and evaluate factors influencing their knowledge. This is a cross-sectional survey enrolling primary school teachers using a self-administered questionnaire. Seventy-three teachers (mean age of 34 years, 66% females) responded. Gaps in awareness and knowledge were found. About 52 (71.2%) teachers identified themselves as having some knowledge about autism, with 23 (44.2%) among this group understanding autism as a neurological/mental disorder. The majority (73.1%) believe that special education is a helpful intervention. The only significant factor that influenced knowledge among teachers was attendance of behavioral classes ( P = 0.01). Results suggest that teachers have an inadequate understanding of autism due to several misconceptions. This calls for increased education of teachers with regard to autism and other childhood disorders.

The relevance of Public Health Genomics (PHG) education among public health specialists has been recently acknowledged by the Association of Schools of Public Health in the European Region. The aim of this cross-sectional survey was to assess the prevalence of post-graduate public health schools for medical doctors which offer PHG training in Italy. The directors of the 33 Italian public health schools were interviewed for the presence of a PHG course in place. We stratified by geographical area (North, Centre and South) of the schools. We performed comparisons of categorical data using the chi-squared test. The response rate was 73% (24/33 schools). Among respondents, 15 schools (63%) reported to have at least one dedicated course in place, while nine (38%) did not, with a significant geographic difference. Results showed a good implementation of courses in PHG discipline in Italian post-graduate public health schools. However further harmonization of the training programs of schools in public health at EU level is needed.

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.

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

Lower urinary tract dysfunction in school-aged children is common and yet data are lacking on current teacher practice regarding bathroom use and daytime incontinence during classroom hours. We determined the prevalence of elementary school teachers who promote lower urinary tract health and identified predictors for and against such behavioral promotion. We performed an electronic cross-sectional survey among self-identified teachers using targeted social media advertisement during a 1-week period in July 2014. The empirical survey tool consisted of 27 questions and collected data on 5 principal domains, including 1) teacher demographics, 2) rules and regulations on water intake and bathroom use during classroom hours, 3) characteristics of school bathrooms in terms of safety, supervision and suitability for use, 4) experience with and management of students with daytime incontinence and 5) training on the topic of lower urinary tract health. Predictors for promoting lower urinary tract health were identified by multivariable logistic regression. Of the 4,166 teachers who completed the survey 88% indicated that they encourage students to hold urine. Despite strict bathroom protocols 81% of teachers allowed children unlimited access to water. Of the teachers 82% reported never having undergone any professional development on bathroom regulations for children. Overall only 24% of surveyed teachers met criteria for promoting lower urinary tract health. The odds of promoting lower urinary tract health decreased with ascending grade level (OR 0.80, 95% CI 0.76-0.84). Conversely it increased if teaching experience was greater than 5 years (OR 1.66, 95% CI 1.39-1.98) or professional development on the subject had been received (OR 1.42, 95% CI 1.18-1.70). Of elementary school teachers 76% are not promoting lower urinary tract health in school-aged children.

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.

Decisions by anaesthesiologists directly impact the treatment, safety, recovery and quality of life of patients. Physical or mental collapse due to overwork or stress (burnout) in anaesthesiologists may, therefore, be expected to negatively affect patients, departments, healthcare facilities and families. To evaluate the prevalence of burnout among anaesthesiologists in Belgrade public teaching hospitals. A cross-sectional survey. Anaesthesiologists in 10 Belgrade teaching hospitals. Burnout was assessed using Maslach Burnout Inventory-Human Services Survey. The response rate was 76.2% (205/272) with the majority of respondents women (70.7%). The prevalence of total burnout among anaesthesiologists in Belgrade teaching hospitals was 6.34%. Measured level of burnout as assessed by high emotional exhaustion, high depersonalisation and low personal accomplishment was 52.7, 12.2 and 28.8%, respectively. More than a quarter of the studied population responded in each category with symptoms of moderate burnout. We detected that sex, additional academic education, marital status and working conditions were risk factors for emotional exhaustion and depersonalisation. Ageing increased the likelihood of burnout by 21.3% with each additional year. Shorter professional experience and increased educational accomplishment increased the risk of total burnout by 272%. Burnout rates in Belgrade teaching hospitals among anaesthesiologists are higher than in foreign hospitals. Emotional and/or physical breakdowns can have serious effects when these individuals care for patients in extremely stressed situations that may occur perioperatively. Causes for burnout should be examined more closely and means implemented to reverse this process.

Specialty satisfaction, positive psychological capital, and nursing professional values in nursing students: A cross-sectional survey.

Ideally, college majors should be chosen to achieve self-realization and correspond to self-concept. However, some students select a major based on extrinsic factors, rather than aptitude or interests, because of a lack of employment opportunities. If they have negative college experiences with an unsatisfactory major, they might not engage fully in their occupation following graduation. This study aimed to identify factors affecting specialty satisfaction in preclinical practice nursing-college students. A cross-sectional descriptive survey. A nonprobability convenience sample of 312 nursing-college students at colleges in Deajeon City, South Korea. The survey questionnaire was distributed to those who agreed to participate. Freshmen and sophomore nursing students (n=312). Participants were 312 students at colleges in Deajeon City. A structured questionnaire was used to collect data, which were analyzed using SPSS/WIN. Positive psychological capital and nursing professional values were positively correlated with specialty satisfaction. Significant predictors for specialty satisfaction included hope and optimism (as components of positive psychological capital), the roles of nursing service and originality of nursing (as nursing professional values), and aptitude/interests and job value (as motives for selecting a major). The findings suggested that nursing students' specialty satisfaction was partially linked to positive psychological capital and professional values. Therefore, the promotion of positive factors should be useful in enhancing specialty satisfaction in preclinical-practice nursing-college students. Copyright © 2017 Elsevier Ltd.

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. 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. 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. 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. 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. Published by the BMJ Publishing Group Limited.

Pressure Dependence of Excitation Cross Sections for Resonant Levels of Rare Gases

NASA Astrophysics Data System (ADS)

Stewart, Michael D.; Chilton, J. Ethan; Lin, Chun C.

2000-06-01

In the rare gases, the excited n'p^5ns and n'p^5nd levels with J = 1 are optically coupled to ground as well as lower lying p levels. Resonant photons emitted when the atom decays to ground can be reabsorbed by another ground-state atom. At low gas pressures this reabsorption occurs infrequently, but at higher pressures becomes increasingly likely until the resonant transition is completely suppressed. This enhances the cascade transitions into lower p levels, resulting in pressure dependent optical emission cross sections. This reabsorption process can be understood quantitatively with a model developed by Heddle et al(D. W. O. Heddle and N. J. Samuel, J. Phys. B 3), 1593 (1970).. The radiation from transitions into the nonresonant levels often lie in the ir, while the resonant radiation is always in the uv spectral region. Using a Fourier-transform spectrometer, one can measure the cross sections for the ir transitions as a function of pressure. The Heddle model can be fit to these data with the use of theoretical values for the Einstein A coefficients. This provides a test of the accuracy of calculated A values. Discussion will include cross section measurements for Ne, Ar, and Kr excited by electron impact over a range of gas pressures.

Nursing is an emotionally demanding profession and deficiencies in nurses' mental wellbeing, characterised by low vitality and common mental disorders, have been linked to low productivity, absenteeism and presenteeism. Part of a larger study of nurses' health, the aim of this paper was to describe the mental health status and related characteristics of nurses working in two acute metropolitan teaching hospitals. A cross sectional survey design was used. The Registered and Enrolled Nurse workforce, employed on any form of contract, at two teaching hospitals in Sydney Australia were invited to participate. The survey tool was compiled of validated tools and questions. Family and medical history and health risk-related characteristics, current psycho-active medications, smoking status, alcohol intake, eating disorders, self-perceived general health, mental health and vitality, demographic, social and occupational details were collected. A total of 1215 surveys were distributed with a usable response rate of 382 (31.4%). Altogether 53 nurses (14%) reported a history of mental health disorders, of which n = 49 (13%) listed diagnoses of anxiety and/or depression; 22 (6%) were currently taking psychoactive medication. Symptoms that could potentially indicate a mental health issue were more common, with 248 (65.1%) reporting they had experienced symptoms sometimes or often in the last 12 month. Nurses had better mental health if they had better general health, lived with a spouse/ partner rather than alone, had fewer symptoms, sleep problems or disordered eating behaviours, were not an informal carer and did not work nights. Nurses had greater vitality if they were male, had better general health, fewer sleep problems or symptoms generally and lived with a spouse/ partner rather than alone; less vitality if they were an informal carer or had disordered eating. Nurses and their managers should strive to create workplaces where working practices promote nurses' health

Although there is a call for patient-centred prenatal care, women's preferences for and concerns about preterm birth (PTB) prevention have not been well-studied. Therefore, we conducted a cross-sectional survey to determine women's preferences for PTB prevention and their likelihood of following their healthcare provider's recommendations for PTB prevention, as well as factors associated with these responses. A piloted self-administered questionnaire was completed by pregnant women who could read English. Data were collected about their preferences for and concerns about PTB prevention, and the likelihood of following their healthcare provider's recommendations, using multivariable logistic regression to control for other factors. Three hundred and eleven women at a median of 32-weeks of gestation completed the survey, a response rate of 85.2%. Most women reported that if they were told they were at increased risk for PTB, they preferred not to use PTB prevention (65.8%), of whom almost all (93.4%) reported they preferred close-monitoring and 6.6% preferred neither monitoring nor prevention. A much smaller proportion of women reported that they would not follow their healthcare provider's recommendation for progesterone (10.9%) compared to pessary (28.7%) or cerclage (50.2%). Women who were neither married nor in a common-law relationship were more likely to report that they would not follow recommendations for progesterone (aOR = 5.88 [95% CI: 1.72, 20.00]). Most women (84.5%) reported they would use other sources of information other than their main healthcare provider to learn more about PTB prevention, with the most popular source being the internet. Most women reported that if they were told they were at increased risk of PTB, they preferred close-monitoring over using PTB prevention. Their reported likelihood of not following their healthcare provider's recommendations for PTB prevention varied from 10.9% for progesterone to 50.2% for cerclage. These

It is well known that job burnout is a major problem for many professions. Correctional officers, the most important driving force in correctional facilities, deal with unwilling and potentially violent populations, and this may lead to burnout. However, in China, few studies are available regarding burnout among correctional officers and associations with work-related factors. The aim of this study was to explore the impact of work characteristics on job burnout among Chinese correctional officers in public prisons. Cross-sectional survey. This cross-sectional study was performed in March/April 2011. The study population comprised 2185 correctional officers working in four prisons in a province in north-east China. A questionnaire that examined job burnout [three subscales: emotional exhaustion (EE), cynicism (CY) and professional efficacy (PE)], work conditions, occupational stress and demographic factors was distributed to these correctional officers. In total, 1769 responses were received (response rate 81%). Multiple logistic regression was used to explore the factors related to burnout. Mean (±standard deviation) scores were 10.59 ± 7.51 for EE, 9.65 ± 6.56 for CY and 23.90 ± 9.39 for PE. Strong extrinsic effort and reward were the most powerful predictors of job burnout; an imbalance between effort and reward at work and perceived threat was mainly associated with EE and CY, and strong overcommitment was mainly associated with EE and PE. Chinese correctional officers experience a slightly higher level of job burnout, and this is affected by work-related stress. It is important to reduce occupational stress in correctional officers and improve disadvantageous work conditions in order to reduce burnout in this population.

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.

Background. The objectives of the study were to explore the knowledge and attitudes of Pakistani university students toward mental illnesses. People with mental illnesses are challenged not only by their symptoms but also by the prejudices associated with their illness. Acknowledging the stigma of mental illness should be the first essential step toward devising an appropriate treatment plan. Methods. A cross-sectional survey was conducted at the University of Punjab, Lahore, CMH Lahore Medical and Dental College, Lahore, and University of Sargodha, Sub-campus Lahore, from February to May 2014. The self-administered questionnaire consisted of three sections: demographics, general knowledge of psychiatric illnesses, and Community Attitudes towards Mental Illnesses (CAMI) Scale. The questionnaire was distributed to 650 participants enrolled in different disciplines (Social Sciences, Medicine and Formal Sciences). Results. Response rate was 81% (527/650 respondents). Mean age was 20.98 years. Most of the students (331, 62.8%) had an urban background and studied Social Sciences (238, 45.2%). Four hundred and eighteen respondents (79.3%) considered religion very important and most respondents considered psychiatrists (334, 63.4%) and spiritual leaders (72, 13.7%) to be best able to treat mental illnesses. One hundred and sixty nine respondents (32.1%) considered black magic to be a cause of mental illness. Only 215 (41%) respondents had ever read an article on mental illnesses. Multiple regression analysis revealed study discipline, exposure, perceived causes of mental illnesses and superstitions to be significantly associated with attitudes towards mental illnesses (p < .05). Conclusion. Although low awareness and exposure were found in this sample of Pakistani university students, their attitude towards mental illnesses was generally positive. Most respondents gave supernatural explanations for mental illnesses but only a few believed that spiritual leaders can play a

The radar cross section of dielectric disks

A solution is presented for the backscatter (nonstatic) radar cross section of dielectric disks of arbitrary shape, thickness and dielectric constant. The result is obtained by employing a Kirchhoff type approximation to obtain the fields inside the disk. The internal fields induce polarization and conduction currents from which the scattered fields and the radar cross section can be computed. The solution for the radar cross section obtained in this manner is shown to agree with known results in the special cases of normal incidence, thin disks and perfect conductivity. The solution can also be written as a product of the reflection coefficient of an identically oriented slab times the physical optics solution for the backscatter cross section of a perfectly conducting disk of the same shape. This result follows directly from the Kirchhoff type approximation without additional assumptions.

Bangladesh is facing the unavoidable challenge of adaptation to climate change. However, very little is known in relation to climate change and health. This article provides information on potential climate change impact on health, magnitude of climate-sensitive diseases, and baseline scenarios of health systems to climate variability and change. A cross-sectional study using multistage cluster sampling framework was conducted in 2012 among 6,720 households of 224 rural villages in seven vulnerable districts of Bangladesh. Information was obtained from head of the households using a pretested, interviewer-administered, structured questionnaire. A total of 6,720 individuals participated in the study with written, informed consent. The majority of the respondents were from the low-income vulnerable group (60% farmers or day labourers) with an average of 30 years' stay in their locality. Most of them (96%) had faced extreme weather events, 45% of people had become homeless and displaced for a mean duration of 38 days in the past 10 years. Almost all of the respondents (97.8%) believe that health care expenditure increased after the extreme weather events. Mean annual total health care expenditure was 6,555 Bangladeshi Taka (BDT) (1 USD=77 BDT in 2015) and exclusively out of pocket of the respondents. Incidence of dengue was 1.29 (95% CI 0.65-2.56) and malaria 13.86 (95% CI 6.00-32.01) per 1,000 adult population for 12 months preceding the data collection. Incidence of diarrhoea and pneumonia among under-five children of the households for the preceding month was 10.3% (95% CI 9.16-11.66) and 7.3% (95% CI 6.35-8.46), respectively. The findings of this survey indicate that climate change has a potential adverse impact on human health in Bangladesh. The magnitude of malaria, dengue, childhood diarrhoea, and pneumonia was high among the vulnerable communities.

Quantitative cross-linking/mass spectrometry (QCLMS) is an emerging approach to study conformational changes of proteins and multi-subunit complexes. Distinguishing protein conformations requires reproducibly identifying and quantifying cross-linked peptides. Here we analyzed the variation between multiple cross-linking reactions using bis[sulfosuccinimidyl] suberate (BS3)-cross-linked human serum albumin (HSA) and evaluated how reproducible cross-linked peptides can be identified and quantified by LC-MS analysis. To make QCLMS accessible to a broader research community, we developed a workflow that integrates the established software tools MaxQuant for spectra preprocessing, Xi for cross-linked peptide identification, and finally Skyline for quantification (MS1 filtering). Out of the 221 unique residue pairs identified in our sample, 124 were subsequently quantified across 10 analyses with coefficient of variation (CV) values of 14% (injection replica) and 32% (reaction replica). Thus our results demonstrate that the reproducibility of QCLMS is in line with the reproducibility of general quantitative proteomics and we establish a robust workflow for MS1-based quantitation of cross-linked peptides.

Are public health professionals prepared for public health genomics? A cross-sectional survey in Italy

PubMed Central

2014-01-01

Background Public health genomics is an emerging multidisciplinary approach, which aims to integrate genome-based knowledge in a responsible and effective way into public health. Despite several surveys performed to evaluate knowledge, attitudes and professional behaviors of physicians towards predictive genetic testing, similar surveys have not been carried out for public health practitioners. This study is the first to assess knowledge, attitudes and training needs of public health professionals in the field of predictive genetic testing for chronic diseases. Methods A self-administered questionnaire was used to carry out a cross-sectional survey of a random sample of Italian public health professionals. Results A response rate of 67.4% (797 questionnaires) was achieved. Italian public health professionals have the necessary attitudinal background to contribute to the proper use of predictive genetic testing for chronic diseases, but they need additional training to increase their methodological knowledge. Knowledge significantly increases with exposure to predictive genetic testing during postgraduate training (odds ratio (OR) = 1.74, 95% confidence interval (CI) = 1.05–2.88), time dedicated to continuing medical education (OR = 1.53, 95% CI = 1.14–2.04) and level of English language knowledge (OR = 1.36, 95% CI = 1.07–1.72). Adequate knowledge is the strongest predictor of positive attitudes from a public health perspective (OR = 3.98, 95% CI = 2.44–6.50). Physicians show a lower level of knowledge and more public health attitudes than other public health professionals do. About 80% of public health professionals considered their knowledge inadequate and 86.0% believed that it should be improved through specific postgraduate training courses. Conclusions Specific and targeted training initiatives are needed to develop a skilled public health workforce competent in identifying genomic technology that is ready for use in

The aim of this study was to examine the knowledge, attitudes and practices of Australian general practice nurses (GPNs) regarding influenza vaccination. Despite the evidence for the benefits of influenza vaccination, vaccination rates remain sub-optimal. The knowledge, attitudes and practices of nurses both affects vaccination rates and the advice given to consumers. Given their significant role in opportunistic and planned vaccinations, GPNs are in an optimal position to positively influence vaccination rates. A descriptive cross-sectional survey was used. GPNs were recruited by email to complete an online survey. The survey tool comprised the King's College Nurses' Influenza Vaccination Questionnaire and adapted demographic items. Data analysis used descriptive and inferential statistics. Open-ended questions were analysed using thematic analysis. Most of the 85 respondents had received the seasonal influenza vaccination in the last year (n = 67; 78·8%); fewer received the H1N1 vaccination (n = 54; 63·5%). Intention to receive vaccination was affected by previous vaccination. Those who had received the seasonal influenza vaccine in the last year had a higher total knowledge score. The seasonal and total influenza knowledge score was high, with lower scores on the H1N1 sub-scale. A positive correlation was identified between influenza knowledge and risk perception. This study highlighted the high level of knowledge amongst GPNs related to seasonal influenza, whilst identifying a knowledge deficit around the H1N1 items. It demonstrated that GPN's knowledge of seasonal influenza was related to vaccination status and risk perception. Further research is required to explore how this translates into the advice GPNs give to consumers. Influenza vaccination should be considered as a key topic for GPNs ongoing professional development. The evidence for links between education and vaccination uptake should encourage employers to facilitate opportunities for this

Background Socially withdrawn youth belong to an emerging subgroup of youth who are not in employment, education, or training and who have limited social interaction intention and opportunities. The use of the internet and social media is expected to be an alternative and feasible way to reach this group of young people because of their reclusive nature. Objective The aim of this study was to explore the possibility of using various social media platforms to investigate the existence of the phenomenon of youth social withdrawal in 3 major cities in China. Methods A cross-sectional open Web survey was conducted from October 2015 to May 2016 to identify and reach socially withdrawn youth in 3 metropolitan cities in China: Beijing, Shanghai, and Shenzhen. To advertise the survey, 3 social media platforms were used: Weibo, WeChat, and Wandianba, a social networking gaming website. Results In total, 137 participants completed the survey, among whom 13 (9.5%) were identified as belonging to the withdrawal group, 7 (5.1%) to the asocial group, and 9 (6.6%) to the hikikomori group (both withdrawn and asocial for more than 3 months). The cost of recruitment via Weibo was US $7.27 per participant. Conclusions Several social media platforms in China are viable and inexpensive tools to reach socially withdrawn youth, and internet platforms that specialize in a certain culture or type of entertainment appeared to be more effective in reaching socially withdrawn youth.

The objectives of this study were to explore current provision of laparoscopic simulation training, and to determine attitudes of trainers and trainees to the role of simulators in surgical training across the UK. An anonymous cross-sectional survey with cluster sampling was developed and circulated. All Royal College of Obstetricians and Gynaecologists (RCOG) Training Programme Directors (TPD), College Tutors (RCT) and Trainee representatives (TR) across the UK were invited to participate. One hundred and ninety-six obstetricians and gynaecologists participated. Sixty-three percent of hospitals had at least one box trainer, and 14.6% had least one virtual-reality simulator. Only 9.3% and 3.6% stated that trainees used a structured curriculum on box and virtual-reality simulators, respectively. Respondents working in a Large/Teaching hospital (p = 0.008) were more likely to agree that simulators enhance surgical training. Eighty-nine percent agreed that simulators improve the quality of training, and should be mandatory or desirable for junior trainees. Consultants (p = 0.003) and respondents over 40 years (p = 0.011) were more likely to hold that a simulation test should be undertaken before live operation. Our data demonstrated, therefore, that availability of laparoscopic simulators is inconsistent, with limited use of mandatory structured curricula. In contrast, both trainers and trainees recognise a need for greater use of laparoscopic simulation for surgical training.

This article reports electron impact ionisation cross sections for platinum-based drugs viz., cisplatin (H6N2Cl2Pt), carboplatin (C6H12N2O4Pt), oxaliplatin (C8H14N2O4Pt), nedaplatin (C2H8N2O3Pt) and satraplatin (C10H22ClN2O4Pt) complexes used in the cancer chemotherapy. The multi-scattering centre spherical complex optical potential formalism is used to obtain the inelastic cross section for these large molecules upon electron impact. The ionisation cross section is derived from the inelastic cross section employing complex scattering potential-ionisation contribution method. Comparison is made with previous results, where ever available and overall a reasonable agreement is observed. This is the first attempt to report total ionisation cross sections for nedaplatin and satraplatin complexes.

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.

Pregnant women are routinely prescribed medicines while self-medicating with herbal natural products to treat predominantly pregnancy related conditions. The aim of this study was to assess the potential for herb-drug interactions (HDIs) in pregnant women and to explore possible herb-drug interactions and their potential clinical significance. A cross-sectional survey of women during early pregnancy or immediately postpartum in North-East Scotland. Outcome measures included; Prescription medicines use excluding vitamins and potential HDIs assessed using Natural Medicines Comprehensive Database. The survey was completed by 889 respondents (73% response rate). 45.3% (403) reported the use of at least one prescription medicine, excluding vitamins. Of those taking prescription medicines, 44.9% (181) also reported concurrent use of at least one HNP (Range 1-12). A total of 91 different prescription medicines were reported by respondents using HNPs. Of those taking prescription medicines, 44.9% (181) also reported concurrent use of at least one HNP (Range 1-12). Thirty-four herb-drug interactions were identified in 23 (12.7%) women with the potential to increase the risk of postpartum haemorrhage, alter maternal haemodynamics, and enhance maternal/fetal CNS depression. Almost all were rated as moderate (93.9%), one as a potentially major (ginger and nifedipine) and only one minor (ondansetron and chamomile). Almost half of pregnant women in this study were prescribed medicines excluding vitamins and minerals and almost half of these used HNPs. Potential moderate to severe HDIs were identified in an eighth of the study cohort. Healthcare professionals should be aware that the concurrent use of HNPs and prescription medicines during pregnancy is common and carries potential risks.

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.

This article shares an in-depth summary of a formative evaluation that used quantitative data to inform the development and selection of promotional ads for the antismoking communication component of a social marketing campaign. A foundational survey provided cross-sectional data to identify beliefs about quitting smoking that campaign messages should target, as well as beliefs to avoid. Pretesting draft ads against quantitative indicators of message effectiveness further facilitated the selection and rejection of final campaign ads. Finally, we consider lessons learned from the process of balancing quantitative methods and judgment to make formative decisions about more and less promising persuasive messages for campaigns.

2016-01-01

Predicting thermoelastic damping (TED) is crucial in the design of high Q micro-resonators. Microrings are often critical components in many micro-resonators. Some analytical models for TED in microrings have already been developed in the past. However, the previous works are limited to the microrings with rectangular cross-section. The temperature field in the rectangular cross-section is one-dimensional. This paper deals with TED in the microrings with circular cross-section. The temperature field in the circular cross-section is two-dimensional. This paper first presents a 2-D analytical model for TED in the microrings with circular cross-section. Only the two-dimensional heat conduction in the circular cross-section is considered. The heat conduction along the circumferential direction of the microring is neglected in the 2-D model. Then the 2-D model has been extended to cover the circumferential heat conduction, and a 3-D analytical model for TED has been developed. The analytical results from the present 2-D and 3-D models show good agreement with the numerical results of FEM model. The limitations of the present 2-D analytical model are assessed.

We extended the classic anorthoscopic viewing procedure to test a model of visualization of 3D structures from 2D cross-sections. Four experiments were conducted to examine key processes described in the model, localizing cross-sections within a common frame of reference and spatiotemporal integration of cross sections into a hierarchical object representation. Participants used a hand-held device to reveal a hidden object as a sequence of cross-sectional images. The process of localization was manipulated by contrasting two displays, in-situ vs. ex-situ, which differed in whether cross sections were presented at their source locations or displaced to a remote screen. The process of integration was manipulated by varying the structural complexity of target objects and their components. Experiments 1 and 2 demonstrated visualization of 2D and 3D line-segment objects and verified predictions about display and complexity effects. In Experiments 3 and 4, the visualized forms were familiar letters and numbers. Errors and orientation effects showed that displacing cross-sectional images to a remote display (ex-situ viewing) impeded the ability to determine spatial relationships among pattern components, a failure of integration at the object level.

Few studies have described the challenges experienced by long-term care facilities (LTCFs) following Hurricane Sandy. This study examined LTCF preparedness and experiences during and after the storm. A cross-sectional survey was conducted 2 years after Hurricane Sandy to assess LTCF demographics, preparation, and post-storm resources. Surveys were conducted at LTCFs located on the Rockaway Peninsula of New York City. All LTCFs located in a heavily affected area were approached. Of 29 facilities, 1 had closed, 5 did not respond, 9 declined to participate, and 14 participated, yielding a response rate of 50% for open facilities. Twenty-one percent of the facilities had preparations specifically for hurricanes. More than 70% of the facilities had lost electricity, heat, and telephone service, and one-half had evacuated. Twenty-one percent of the facilities reported not receiving any assistance and over one-half reported that relief resources did not meet their needs. Many LTCFs lacked plans specific to such a large-scale event. Since nearly all of the LTCFs in the region were affected, preexisting transportation and housing plans may have been inadequate. Future preparation could include hazard-specific planning and reliance on resources from a wider geographic area. Access to electricity emerged as a top priority.

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.

Head and neck cancer (HNC) survivors have substantial psychological distress in addition to treatment-related side effects. This study examines the long-term quality of life (QOL) of HNC survivors in a busy tertiary care center. A prospective, cross-sectional survey was conducted studying 212 HNC survivors 1 year after completion of their treatment at a tertiary cancer center. Quality of life assessments were performed using the 2 standardized health-related QOL questionnaires: The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 and The Quality of Life Questionnaire Head and Neck Cancer Module. The overall global QOL rating for the study cohort was satisfactory. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 scores showed that the domains where most patients faired poorly included financial difficulties (54%), appetite loss (36%), fatigue (33%), and cough (30%). The Quality of Life Questionnaire Head and Neck Cancer Module scale identified the domains with poor scores to be dry mouth (64%), dental problems (42%), sticky saliva (40%), cough (39%), and problems with mouth opening (32%). Patients with early-stage tumors and those treated with surgery alone had significantly better QOL scores when compared with advanced stage tumors and patients receiving either radiation alone or multimodality treatment, respectively. Quality of life questionnaires provide a medium for patients to effectively communicate with their physician in a busy tertiary care facility and provide an insight into the physical, psychological, and social problems affecting our patients which can then direct future interventions.

To evaluate the prevalence, awareness and management of acute faecal incontinence with diarrhoea (AFId) in the Intensive Care Unit. Cross-sectional descriptive survey design of intensive care units across Germany, Italy, Spain and the United Kingdom. 962 questionnaires were completed by nurses (60%), physicians (29%) and pharmacists or purchasing personnel (11%). The estimated prevalence of AFId ranged from 9 to 37% of patients on the day of the survey. The majority of respondents reported a low-moderate awareness of the clinical challenges associated with AFId. Patients with AFId commonly had compromised skin integrity, which included perineal dermatitis, moisture lesions or sacral pressure ulcers. Reducing the risk of cross-infection and protecting skin integrity were rated as the most important clinical challenges. 49% had no hospital protocol or guideline for AFId management. There was also a low awareness of nursing time spent managing AFId; 60% of respondents estimated that 10-20 minutes are required for managing an AFId episode by 2-3 healthcare staff. AFId in the critical care setting may be an underestimated problem which is associated with a high use of nursing time. Copyright © 2012 Elsevier Ltd. All rights reserved.

The NHS Plan required extensive changes in the configuration of mental health services in the UK, including introduction of crisis resolution teams, CRTs. Little is known about the effects of these changes on mental health staff and their recruitment and retention. To assess levels of burnout and sources of satisfaction and stress in CRT staff and compare them with assertive outreach team (AOT) and community mental health team (CMHT) staff. Cross sectional survey using questionnaires, including the Maslach Burnout Inventory, the Minnesota Satisfaction Scale and global job satisfaction item from the Job Diagnostic Survey. All staff in 11 CRTs in 7 London boroughs were included. One hundred and sixty-nine questionnaires were received (response rate 78%). CRT staff were moderately satisfied with their jobs and scores for the three components of burnout were low or average. Their sense of personal accomplishment was greater than in the other types of team. Our results suggest that CRTs may be sustainable from a workforce morale perspective, but longer term effects will need to be assessed.

Recently, nucleon-nucleon (N-N) cross sections in the medium have been extracted directly from experiment. The in-medium N-N cross sections form the basic ingredients of several heavy-ion scattering approaches including the coupled-channel approach developed at the Langley Research Center. In the present study the ratio of the real to the imaginary part of the two-body scattering amplitude in the medium was investigated. These ratios are used in combination with the in-medium N-N cross sections to calculate total proton-nucleus cross sections. The agreement is excellent with the available experimental data. These cross sections are needed for the radiation risk assessment of space missions.

Study Objective: The objective of this study was to examine the association between the use of mobile phones after lights out and sleep disturbances among Japanese adolescents. Design and Setting: This study was designed as a cross-sectional survey. The targets were students attending junior and senior high schools throughout Japan. Sample schools were selected by cluster sampling. Self-reported anonymous questionnaires were sent to schools for all students to fill out. Participants: A total of 95,680 adolescents responded. The overall response rate was 62.9%, and 94,777 questionnaires were subjected to analysis. Intervention: N/A Measurements and Results: Daily mobile phone use, even if only for a brief moment every day, was reported by 84.4%. Moreover, as for use of mobile phones after lights out, 8.3% reported using their mobile phone for calling every day and 17.6% reported using it for sending text messages every day. Multiple logistic regression analysis showed that mobile phone use for calling and for sending text messages after lights out was associated with sleep disturbances (short sleep duration, subjective poor sleep quality, excessive daytime sleepiness, and insomnia symptoms) independent of covariates and independent of each other. Conclusion: This study showed that the use of mobile phones for calling and for sending text messages after lights out is associated with sleep disturbances among Japanese adolescents. However, there were some limitations, such as small effect sizes, in this study. More studies that examine the details of this association are necessary to establish strategies for sleep hygiene in the future.

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.

Background: Changes in modern societies develop the perception that the external environment is essential in organization’s practices, especially in the way they deal with aspects such as human rights, community needs, market demands and environmental interests. These issues are usually under the umbrella of the concept of social responsibility. Given the importance of this concept in the context of health care delivery, suggesting a new paradigm in hospital governance, the aim of this study was to measure the social responsibility in hospitals. Methods: A cross-sectional survey was employed to collect data from a sample of 946 hospital staff of Isfahan city. Data was obtained by structured and valid self-administrated questionnaire and analyzed by descriptive and analytic statistics using SPSS. Results: The mean score of hospitals’ social responsibility was 3.0 compared with the justified range from 1.0 to 5.0. Results showed that there was a significant relationship between social responsibility score and hospitals’ ownership (public or private). Also, there was no significant relationship between social responsibility and type of hospital specialty. Conclusion: It is recommended that hospital managers develop and apply appropriate policies and strategies to improve their hospitals’ social responsibility level, especially through concentrating on their staff’s working environment.

Graduate entry programs leading to registration are gaining momentum in nursing. These programs attract student cohorts with professional, cultural, gender and age diversity. As a consequence of this diversity, such accelerated programs challenge traditional pedagogical methods used in nursing and require different approaches. To date, however, there has been limited research on the learning styles of students undertaking these programs to inform academics involved in their delivery. Kolb's Experiential Learning model has been used widely in a variety of educational settings because it is based on the theory of experiential learning. More recently VARK (Visual, Aural, Read/write and Kinaesthetic) model has become popular. The aim of this study was to investigate the learning styles of two cohorts of graduate entry nursing students undertaking an accelerated masters-level program. This was a cross-sectional survey of two cohorts of Master of Nursing Practice students enrolled at a large Australian university. The students were more inclined toward converging (practical) and least toward concrete experience (experiencing) learning styles. The majority of students were more inclined toward kinaesthetic and least toward aural learning style. Findings have implications for academics engaged in teaching graduate entry nursing students.

Cases of West Nile Virus (WNV) disease were recorded for three consecutive years in Greece following the year 2010 outbreak. A cross-sectional serologic survey was conducted to estimate the WNV seroprevalence and assess the ratio of infection to neuroinvasive disease. A stratified left-over sampling methodology was used including age and residence strata. A total of 3,962 serum samples was collected and tested for WNV Immunoglobulin G (IgG) antibodies by Enzyme–Linked Immunosorbent Assay (ELISA). All positive samples were further tested by Plaque Reduction Neutralization Test (PRNT) and WNV Immunoglobulin M (IgM) antibodies. WNV IgG antibodies were detected in 82 samples and 61 were also positive in PRNT representing a weighted seroprevalence of 2.1% (95% C.I.: 1.7–2.6) and 1.5% (95% C.I.: 1.2–2.0), respectively. Multivariable analysis showed that seroprevalence was associated with age and residence. The overall ratio of neuroinvasive disease to infected persons was estimated at 1:376 (95% C.I.: 1:421–1:338), while the elderly people had the highest ratio. This nationwide study provided valuable data regarding the epidemiology of WNV in Greece based on the fact that elderly people have higher risk of being both infected and having severe disease.

2011-12-01

The cross section for H on H2 collisions is important for astrophysics as well as our understanding of the simple chemical systems. This is the simplest atom-molecule cross section. With a new H3 potential surface by Mielke et al., we have modified the ABC code by Skouteris, Castillo and Manolopoulos to calculate new cross sections. These cross sections are compared to previous cross section calculations.

The absolute neutron-capture cross section of 242Pu was measured at the Los Alamos Neutron Science Center using the Detector for Advanced Neutron-Capture Experiments array along with a compact parallel-plate avalanche counter for fission-fragment detection. During target fabrication, a small amount of 239Pu was added to the active target so that the absolute scale of the 242Pu(n,γ) cross section could be set according to the known 239Pu(n,f) resonance at En,R = 7.83 eV. The relative scale of the 242Pu(n,γ) cross section covers four orders of magnitude for incident neutron energies from thermal to ≈ 40 keV. The cross section reported in ENDF/B-VII.1 for the 242Pu(n,γ) En,R = 2.68 eV resonance was found to be 2.4% lower than the new absolute 242Pu(n,γ) cross section.

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.

Objective To obtain a comprehensive understanding of the job opinions of hospital professionals by conducting qualitative analyses of the open comments included in a job satisfaction survey and combining these results with the quantitative results. Design A cross-sectional survey targeting all Lausanne University Hospital professionals was performed in the fall of 2013. Material and methods The survey considered ten job satisfaction dimensions (e.g. self-fulfilment, workload, management, work-related burnout, organisational commitment, intent to stay) and included an open comment section. Computer-assisted qualitative analyses were conducted on these comments. Satisfaction rates on the included dimensions and professional groups were entered as predictive variables in the qualitative analyses. Participants Of 10 838 hospital professionals, 4978 participated in the survey and 1067 provided open comments. Data from 1045 respondents with usable comments constituted the analytic sample (133 physicians, 393 nurses, 135 laboratory technicians, 247 administrative staff, including researchers, 67 logistic staff, 44 psycho-social workers, and 26 unspecified). Results Almost a third of the comments addressed scheduling issues, mostly related to problems and exhaustion linked to shifts, work-life balance, and difficulties with colleagues’ absences and the consequences for quality of care and patient safety. The other two-thirds related to classic themes included in job satisfaction surveys. Although some comments were provided equally by all professional groups, others were group specific: work and hierarchy pressures for physicians, healthcare quality and patient safety for nurses, skill recognition for administrative staff. Overall, respondents’ comments were consistent with their job satisfaction ratings. Conclusion Open comment analysis provides a comprehensive understanding of hospital professionals’ job experiences, allowing better consideration of quality

Social, behavioral, and sleep characteristics associated with depression symptoms among undergraduate students at a women’s college: a cross-sectional depression survey, 2012

PubMed Central

2014-01-01

Background The association between student characteristics and depression among students attending women’s colleges (single-sex institutions of higher education that exclude or limit males from admission) is poorly understood. Our objective was to estimate the prevalence of depression and determine behavioral and social characteristics associated with depression among students attending a women’s college. Methods We administered a cross-sectional Internet-based survey between April and May 2012 to students (n = 277) enrolled at a private women’s college in the southeastern US. Center for Epidemiologic Studies Depression (CES-D) and Depression Anxiety Stress Scale 21 (DASS-21) instruments measured self-reported depression. Bivariate and multivariable logistic regression methods were used to estimate adjusted associations. Results Prevalence of depression measured by CES-D and DASS-21 instruments was 26.3% (95% confidence interval [CI] 20.8-32.3%) and 26.0% (95% CI 20.4-32.3%), respectively. After adjusting for confounders, absence of strong social support (prevalence odds ratio [OR] = 4.3, 95% CI 1.4-13.7), history of mental health disorder (OR = 4.8 95% CI 1.9-12.4), and poor sleep hygiene (OR = 2.8, 95% CI 1.3-5.8) were associated with depression. Conclusions This cross-sectional survey identified absence of strong social support, history of mental health disorder, and poor sleep hygiene as potential predictors of depression among students attending a women’s college. Further investigation of these factors may inform depression interventions for students attending women’s colleges and other undergraduate student populations. PMID:24410897

To analyse the incidence and characteristics of medical complaints received by doctors in New Zealand. A cross-sectional survey of New Zealand doctors randomly selected from each of three groups from the New Zealand medical register: vocationally registered general practitioners; vocationally registered hospital-based specialists; and general registrants. Nine hundred and seventy one doctors (11% of registered New Zealand doctors) indicated that 34% had ever received a medical complaint, and 66% had never received one. The rate of complaint in New Zealand is rising. The annual rate of complaint in 2000 was 5.7%, with doctors in the 40-60 age group receiving 68% of complaints. Doctors who were male, vocationally registered general practitioners, and holding higher postgraduate qualifications were more likely to receive a complaint. Time to resolution of a complaint is long, with 74% of dismissed and 59% of upheld complaints being resolved within 12 months. This study finds a high incidence of complaint in New Zealand. It finds differences between doctors based on gender, qualification, and field of practice, and suggests that responsibility for patient care may be an important determinant of the risk of receiving a complaint.

We examined associations between longitudinal neighborhood poverty trajectories and preterm birth (PTB). Using data from the Neighborhood Change Database (1970-2000) and the American Community Survey (2005-2009), we categorized longitudinal trajectories of poverty for California neighborhoods (i.e., census tracts). Birth data included 23 291 singleton California births from the Maternal and Infant Health Assessment (2003-2009). We estimated associations (adjusted for individual-level covariates) between PTB and longitudinal poverty trajectories and compared these to associations using traditional, cross-sectional measures of poverty. Compared to neighborhoods with long-term low poverty, those with long-term high poverty and those that experienced increasing poverty early in the study period had 41% and 37% increased odds of PTB (95% confidence interval [CI] = 1.18, 1.69 and 1.09, 1.72, respectively). High (compared with low) cross-sectional neighborhood poverty was not associated with PTB (odds ratio = 1.08; 95% CI = 0.91, 1.28). Neighborhood poverty histories may contribute to an understanding of perinatal health and should be considered in future research.

Recently [Nucl. Instr. and Meth. B 145 (1998) 277; Extraction of in-medium nucleon-nucleon amplitude from experiment, NASA-TP, 1998], we developed a method of extracting nucleon-nucleon (N-N) cross-sections in the medium directly from experiment. The in-medium N-N cross-sections form the basic ingredients of several heavy-ion scattering approaches including the coupled-channel approach developed at the NASA Langley Research Center. We investigated [Proton-nucleus total cross-sections in coupled-channel approach, NASA/TP, 2000; Nucl. Instr. and Meth. B 173-174 (2001) 391] the ratio of real to imaginary part of the two body scattering amplitude in the medium. These ratios are used in combination with the in-medium N-N cross-sections to calculate proton-nucleus elastic cross-sections. The agreement is excellent with the available experimental data. These cross-sections are needed for the radiation risk assessment of space missions. c2002 Elsevier Science B.V. All rights reserved.

Using quasimonochromatic laser-Compton scattering γ rays, total photoneutron cross sections were measured for 206,207,208Pb near neutron threshold with a high-efficiency 4π neutron detector. Partial E1 and M1 photoneutron cross sections along with total cross sections were determined for 207,208Pb at four energies near threshold by measuring anisotropies in photoneutron emission with linearly polarized γ rays. The E1 strength dominates over the M1 strength in the neutron channel where E1 photoneutron cross sections show extra strength of the pygmy dipole resonance in 207,208Pb near the neutron threshold corresponding to 0.32%-0.42% of the Thomas-Reiche-Kuhn sum rule. Several μN2 units of B(M1)↑ strength were observed in 207,208Pb just above neutron threshold, which correspond to an M1 cross section less than 10% of the total photoneutron cross section.

Exact analytical expressions for the cross-section correlation functions of chaotic scattering systems have hitherto been derived only under special conditions. The objective of the present article is to provide expressions that are applicable beyond these restrictions. The derivation is based on a statistical model of Breit-Wigner type for chaotic scattering amplitudes which has been shown to describe the exact analytical results for the scattering (S)-matrix correlation functions accurately. Our results are given in the energy and in the time representations and apply in the whole range from isolated to overlapping resonances. The S-matrix contributions to the cross-section correlations are obtained in terms of explicit irreducible and reducible correlation functions. Consequently, the model can be used for a detailed exploration of the key features of the cross-section correlations and the underlying physical mechanisms. In the region of isolated resonances, the cross-section correlations contain a dominant contribution from the self-correlation term. For narrow states the self-correlations originate predominantly from widely spaced states with exceptionally large partial width. In the asymptotic region of well-overlapping resonances, the cross-section autocorrelation functions are given in terms of the S-matrix autocorrelation functions. For inelastic correlations, in particular, the Ericson fluctuations rapidly dominate in that region. Agreement with known analytical and experimental results is excellent.

To measure the prevalence of burnout and explore its professional and psychosocial predictors among Swiss primary care practitioners. A cross-sectional postal survey was conducted to measure burnout, work-related stressors, professional and psychosocial characteristics among a representative sample of primary care practitioners. Answers to the Maslach burnout inventory were used to categorize respondents into moderate and high degree of burnout. 1784 physicians responded to the survey (65% response rate) and 1755 questionnaires could be analysed. 19% of respondents had a high score for emotional exhaustion, 22% had a high score for depersonalisation/cynicism and 16% had a low score for professional accomplishment; 32% had a high score on either the emotional exhaustion or the depersonalisation/cynicism scale (moderate degree of burnout) and 4% had scores in the range of burnout in all three scales (high degree of burnout). Predictors of moderate burnout were male sex, age 45-55 years and excessive perceived stress due to global workload, health-insurance-related work, difficulties to balance professional and private life, changes in the health care system and medical care uncertainty. A high degree of burnout was associated with male sex, practicing in a rural area, and excessive perceived stress due to global workload, patient's expectations, difficulties to balance professional and private life, economic constraints in relation to the practice, medical care uncertainty and difficult relations with non-medical staff at the practice. About one third of Swiss primary care practitioners presented a moderate or a high degree of burnout, which was mainly associated with extrinsic work-related stressors. Medical doctors and politicians in charge of redesigning the health care system should address this phenomenon to maintain an efficient Swiss primary care physician workforce in the future.

To identify patterns of asthma control and treatment in Australian adults with asthma. Cross-sectional web-based survey, conducted 1-27 November 2012. Adults with current asthma, at least 16 years of age, drawn randomly from a web-based panel and weighted to reflect national population proportions for people with asthma. Asthma Control Test (ACT) scores; health care utilisation; medication use. 2686 participants completed the survey (57.1% female; median age group, 40-49 years). Mean ACT score was 19.2 (95% CI, 18.9-19.3), with asthma classified as "well controlled" for 54.4% of participants, "not well controlled" for 22.7% and "very poorly controlled" for 23.0%. 60.8% reported using preventer medication (mostly combined inhaled corticosteroid/long-acting β2-agonist) during the previous year. 23.4% had made at least one urgent visit to a general practitioner concerning their asthma, 10.0% at least one emergency department visit. Urgent consultations were more common for "very poorly controlled" than "well controlled" asthma (adjusted odds ratio, urgent GP visits 5.98 [95% CI, 4.75-7.54] and emergency department visits 2.59 [95% CI, 1.91-3.53] respectively). Participants were classified according to asthma symptom control and frequency of preventer medication usage: Those with "well controlled" asthma included Group A (40.0% of participants) who used preventer medication infrequently (less than 5 days a week) or not at all, consistent with mild asthma, and Group B (14.7%), who used it at least 5 days a week. Uncontrolled asthma symptoms were reported by Group C (19.7%) despite regular preventer use, and by Group D (25.7%), who used none or little. This study provides the first data about asthma control and its relationship with treatment in a large representative Australian population. The findings highlight significant preventable asthma morbidity in Australia.

Objectives This study aimed to explore determinants of second pregnancy and underlying reasons among pregnant Chinese women. Design The study was a population-based cross-sectional survey. Setting 16 hospitals in 5 provinces of Mainland China were included. Participants A total of 2345 pregnant women aged 18 years or above were surveyed face to face by investigators between June and August 2015. Main outcome measures The pregnancy statuses (first or second pregnancy) and reasons for entering second pregnancy. Results A total of 1755 (74.8%) and 590 (25.2%) women in their respective first and second pregnancies were enrolled in this study. The most common self-reported reasons for entering second pregnancy among participants included the benefits to the first child (26.1%), love of children (25.8%), adoption of the 2-child policy (11.5%), concerns about losing the first child (7.5%) and suggestions from parents (7.5%). Pregnant women with low (prevalence ratio (PR) 1.96; 95% CI 1.62 to 2.36) and moderate education level (PR 1.97; 95% CI 1.65 to 2.36) were more likely to have a second pregnancy than their higher educated counterparts. Income was inversely associated with second pregnancy. However, unemployed participants (PR 0.79; 95% CI 0.66 to 0.95) were less likely to enter a second pregnancy than those employed. Women with moderate education were 3 times more likely to have a second child following the ‘2-child policy’ than the low education level subgroup. Conclusions 1 in every 4 pregnant women is undergoing a second pregnancy. The benefits of the firstborn or the love of children were the key drivers of a second pregnancy. Low socioeconomic status was positively associated with a second pregnancy as well. The new 2-child policy will have an influence on China's demographics. PMID:28348193

Identifying essential competencies in end-of-life care, as well as general practitioners' (GPs) confidence in these competencies, is essential to guide training and quality improvement efforts in this domain. To determine which competencies in end-of-life care are considered important by GPs, to assess GPs' confidence in these competencies in a European context and their reasons to refer terminally ill patients to a specialist. Cross-sectional postal survey involving a stratified random sample of 2000 GPs in Switzerland in 2014. Survey development was informed by a previous qualitative exploration of relevant end-of-life GP competencies. Main outcome measures were GPs' assessment of the importance of and confidence in 18 attributes of end-of-life care competencies, and reasons for transferring care of terminally-ill patients to a specialist. GP characteristics associated with main outcome measures were tested using multivariate regression models. The response rate was 31%. Ninety-nine percent of GPs considered the recognition and treatment of pain as important, 86% felt confident about it. Few GPs felt confident in cultural (16%), spiritual (38%) and legal end-of-life competencies such as responding to patients seeking assisted suicide (35%) although more than half of the respondents regarded these competencies as important. Most frequent reasons to refer terminally ill patients to a specialist were lack of time (30%), better training of specialists (23%) and end-of-life care being incompatible with other duties (19%). In multiple regression analyses, confidence in end-of-life care was positively associated with GPs' age, practice size, home visits and palliative training. GPs considered non-somatic competencies (such as spiritual, cultural, ethical and legal aspects) nearly as important as pain and symptom control. Yet, few GPs felt confident in these non-somatic competencies. These findings should inform training and quality improvement efforts in this domain, in

Objectives (1)To describe the prevalence and severity of tremor in patients with multiple sclerosis (MS) registered within a large North American MS registry; (2) to provide detailed descriptions on the characteristics and severity of tremor in a subset of registrants and (3) to compare several measures of tremor severity for strength of agreement. Setting The North American Research Committee on MS (NARCOMS) registry. Participants Registrants of NARCOMS reporting mild or greater tremor severity. Outcome measures We determined the cross-sectional prevalence of tremor in the NARCOMS registry over three semiannual updates between fall 2010 and fall 2011. A subset of registrants (n=552) completed a supplemental survey providing detailed descriptions of their tremor. Outcomes included descriptive characteristics of their tremors and correlations between outcome measures to determine the strength of agreement in assessing tremor severity. Results The estimated prevalence of tremor in NARCOMS ranged from 45% to 46.8%, with severe tremor affecting 5.5–5.9% of respondents. In the subset completing the supplemental survey, mild tremor severity was associated with younger age of MS diagnosis and tremor onset than those with moderate or severe tremor. However, tremor severity did not differ by duration of disease or tremor. Respondents provided descriptions of tremor symptoms on the Clinical Ataxia Rating Scale, which had a moderate to good (ρ=0.595) correlation with the Tremor Related Activities of Daily Living (TRADL) scale. Objectively scored Archimedes’ spirals had a weaker (ρ=0.358) correlation with the TRADL. Rates of unemployment, disability and symptomatic medication use increased with tremor severity, but were high even among those with mild tremor. Conclusions Tremor is common among NARCOMS registrants and severely disabling for some. Both ADL-based and symptom-descriptive measures of tremor severity can be used to stratify patients.

2015-01-01

Professional nursing practice is informed by biological, social and behavioural sciences. In undergraduate pre-registration nursing programs, biological sciences typically include anatomy, physiology, microbiology, chemistry, physics and pharmacology. The current gap in the literature results in a lack of information about the content and depth of biological sciences being taught in nursing curricula. The aim of this study was to establish what priority is given to the teaching of science topics in these programs in order to inform an understanding of the relative importance placed on this subject area in contemporary nursing education. This study employed a cross-sectional survey method. This paper reports on the first phase of a larger project examining science content in nursing programs. An existing questionnaire was modified and delivered online for completion by academics who teach science to nurses in these programs. This paper reports on the relative priority given by respondents to the teaching of 177 topics contained in the questionnaire. Of the relatively small population of academics who teach science to nursing students, thirty (n = 30) completed the survey. Findings indicate strong support for the teaching of science in these programs, with particular priority given to the basic concepts of bioscience and gross system anatomy. Of concern, most science subject areas outside of these domains were ranked as being of moderate or low priority. While the small sample size limited the conclusions able to be drawn from this study, the findings supported previous studies that indicated inadequacies in the teaching of science content in nursing curricula. Nevertheless, these findings have raised questions about the current philosophy that underpins nursing education in Australia and whether existing practices are clearly focused on preparing students for the demands of contemporary nursing practice.

Medical students’ personal choice for mode of delivery in Santa Catarina, Brazil: a cross-sectional, quantitative study

PubMed Central

2012-01-01

Background The increase in overall rates of cesarean sections (CS) in Brazil causes concern and it appears that multiple factors are involved in this fact. In 2009, undergraduate students in the first and final years of medical school at the University of Santa Catarina answered questionnaires regarding their choice of mode of delivery. The aim of the study was to evaluate whether the education process affects decision-making regarding the waay of childbirth preferred by medical students. Methods A cross-sectional, quantitative study was conducted based on data obtained from questionnaires applied to medical students. The questions addressed four different scenarios in childbirth, as follows: under an uneventful pregnancy; the mode of delivery for a pregnant woman under their care; the best choice as a healthcare manager and lastly, choosing the birth of their own child. For each circumstance, there was an open question to explain their choice. Results A total of 189 students answered the questionnaires. For any uneventful pregnancy and for a pregnant woman under their care, 8.46% of the students would opt for CS. As a healthcare manager, only 2.64% of the students would recommend CS. For these three scenarios, the answers of the students in the first year did not differ from those given by students in the sixth year. In the case of the student’s own or a partner’s pregnancy, 41.4% of those in the sixth year and 16.8% of those in the first year would choose a CS. A positive association was found between being a sixth year student and a personal preference for CS according to logistic regression (OR = 2.91; 95%CI: 1.03–8.30). Pain associated with vaginal delivery was usually the reason for choosing a CS. Conclusions A higher number of sixth year students preferred a CS for their own pregnancy (or their partner’s) compared to first year students. Pain associated with vaginal delivery was the most common reason given for haven chosen a CS. The students�

'Do as we say, not as we do:' a cross-sectional survey of injuries in injury prevention professionals.

As the leading cause of death and among the top causes of hospitalisation in Canadians aged 1-44 years, injury is a major public health concern. Little is known about whether knowledge, training and understanding of the underlying causes and mechanisms of injury would help with one's own prevention efforts. Based on the Theory of Planned Behaviour, we hypothesised that injury prevention professionals would experience fewer injuries than the general population. An online cross-sectional survey was distributed to Canadian injury prevention practitioners, researchers and policy makers to collect information on medically attended injuries. Relative risk of injury in the past 12 months was calculated by comparing the survey data with injury incidence reported by a comparable subgroup of adults from the (Canadian Community Health Survey (CCHS)) from 2009 to 2010. We had 408 injury prevention professionals complete the survey: 344 (84.5%) women and 63 (15.5%) men. In the previous 12 months, 86 individuals reported experiencing at least one medically attended injury (21,235 people per 100,000 people); with sports being the most common mechanism (41, 33.6%). Fully 84.8% individuals from our sample believed that working in the field had made them more careful. After accounting for age distribution, education level and employment status, injury prevention professionals were 1.69 (95% CI 1.41 to 2.03) times more likely to be injured in the past year. Despite their convictions of increasing their own safety behaviour and that of others, injury prevention professionals' knowledge and training did not help them prevent their own injuries.

1988-01-01

Relative absorption cross sections for hydrogen peroxide vapor were measured over the temperature ranges 285-381 K for lambda = 230 nm-295 nm and 300-381 K for lambda = 193 nm-350 nm. The well established 298 K cross sections at 202.6 and 228.8 nm were used as an absolute calibration. A significant temperature dependence was observed at the important tropospheric photolysis wavelengths lambda over 300 nm. Measured cross sections were extrapolated to lower temperatures, using a simple model which attributes the observed temperature dependence to enhanced absorption by molecules possessing one quantum of O-O stretch vibrational excitation. Upper tropospheric photodissociation rates calculated using the extrapolated cross sections are about 25 percent lower than those calculated using currently recommended 298 K cross sections.

Electron impact ionization cross sections of beryllium-tungsten clusters*

2016-01-01

We report calculated electron impact ionization cross sections (EICSs) of beryllium-tungsten clusters, BenW with n = 1,...,12, from the ionization threshold to 10 keV using the Deutsch-Märk (DM) and the binary-encounter-Bethe (BEB) formalisms. The positions of the maxima of DM and BEB cross sections are mostly close to each other. The DM cross sections are more sensitive with respect to the cluster size. For the clusters smaller than Be4W they yield smaller cross sections than BEB and vice versa larger cross sections than BEB for clusters larger than Be6W. The maximum cross section values for the singlet-spin groundstate clusters range from 7.0 × 10-16 cm2 at 28 eV (BeW) to 54.2 × 10-16 cm2 at 43 eV (Be12W) for the DM cross sections and from 13.5 × 10-16 cm2 at 43 eV (BeW) to 38.9 × 10-16 cm2 at 43 eV (Be12W) for the BEB cross sections. Differences of the EICSs in different isomers and between singlet and triplet states are also explored. Both the DM and BEB cross sections could be fitted perfectly to a simple expression used in modeling and simulation codes in the framework of nuclear fusion research.

2016-08-01

The aim of the study was to assess whether perceptions of organizational politics (defined as self-serving behaviours at the expense of others) influence the prospective associations between nurses' burnout and its consequences, namely, intention to quit and neglect of work. Researchers have previously investigated relationships between nurses' burnout, intention to quit, neglect of work and perceptions of organizational politics in different research models and from different perspectives. As far as we know, no studies have considered whether nurses' perceptions of organizational politics moderate the influence of burnout. A cross-sectional survey using self-report questionnaires. Data were collected by questionnaire from a sample of 456 nurses from six private hospitals in Ankara, Turkey in March 2015. Four different previously designed scales were used to measure research variables (burnout, intention to quit, neglect of work and perceptions of organizational politics). Following confirmatory validity and reliability analyses of data collection instruments, descriptive statistics for each research variable were analysed. Structural regression models were created to assess relationships among variables. Burnout resulted in intention to quit and neglect. Intention to quit partially mediated the association between burnout and neglect. Burnout gave rise to intention to quit slightly more strongly in nurses who had greater perceptions of organizational politics. This study uncovers and emphasizes the moderating role of perceptions of organizational politics in consequences of burnout. This may help hospital managers and nurses to improve costs, efficiency, satisfaction and productivity. © 2016 John Wiley & Sons Ltd.

We have previously documented blinding trachoma to be a serious public health problem in Southern Sudan, with an unusually high prevalence of trachomatous trichiasis (TT) among children. We aimed to investigate risk factors for TT in children in Southern Sudan. Cross-sectional surveys were undertaken in 11 districts between 2001 and 2006, and eligible participants were examined for trachoma signs. Risk factors were assessed through interviews and observations. Using logistic regression, associations between TT in children and potential risk factors were investigated. In total, 11155 children aged 1-14 years from 3950 households were included in the analysis. Overall prevalence of TT was 1.5% (95% CI 1.1-2.1). Factors independently associated with increased odds of TT in children aged 1-14 years were: increasing age (P(trend)<0.001); female gender (odds ratio=1.5; 95% CI 1.1-2.1); increasing proportion of children in the household with trachomatous inflammation-intense (TI) (P(trend)=0.002); and increasing number of adults in the household with TT (P(trend)<0.001). Our study revealed risk factors for TT in children consistent with those previously reported for TT in adults. While the associations of TT in children with TI in siblings and TT in adult relatives merit further investigation, there is an urgent need for trachoma prevention interventions and trichiasis surgery services that are tailored to cater for young children in Southern Sudan.

Objective: Early contact of medical students with pharmaceutical promotion has been shown in many international studies. We assessed the frequency and places of contact of German medical students to pharmaceutical promotion and examined their attitudes toward pharmaceutical promotional activities. Methods: This cross-sectional survey was based on a self-developed questionnaire. It was distributed to all clinical students at the University of Goettingen Medical School in 2010. A 4-point rating scale was used to assess the attitudes toward different statements regarding pharmaceutical promotion. Results: The overall response rate was 55% (702/1287). The proportion of students with direct contact to pharmaceutical sales representatives increased from 21% in the first clinical year up to 77% in the final year. 60% were contacted during their elective clerkship. 80% had accepted promotional gifts. 86% stated their prescribing behavior to be unsusceptible to the influence of accepting promotional gifts. However, 35% of the unsusceptible students assumed doctors to be susceptible. Almost all (90%) reported that dealing with pharmaceutical promotion was never addressed during lectures and 65% did not feel well prepared for interactions with the pharmaceutical industry. 19% agreed to prohibit contacts between medical students and the pharmaceutical industry. Conclusions: German medical students get in contact with pharmaceutical promotion early and frequently. There is limited awareness for associated conflicts of interests. Medical schools need to regulate contacts and incorporate the topic in their curriculum to prepare students for interactions with the pharmaceutical industry. PMID:25228934

To understand staff factors associated with patient aggression towards the staff of an inpatient forensic psychiatric hospital. Violence by patients is a serious concern in psychiatric hospitals and staff are the most frequent targets of physical and verbal assault. Assault and its consequences can severely disrupt the hospital environment and impair the functioning of staff members and patients. This study examined the interplay of staff dispositional and interpersonal factors associated with patient violence. This cross-sectional study surveyed the staff of a large public forensic hospital. A sample of 348 psychiatric staff participated in an online survey about their workplace experiences, psychosocial characteristics and well-being. Data were collected from November - December 2011. Nearly all staff reported verbal conflict with patients (99%) and 70% reported being assaulted during the previous 12 months. Verbal conflict with other staff (92%) was also high. Multiple regression analyses indicated that in addition to static risk factors (i.e. staff position, years of experience and gender), the risk of assault was associated with the frequency of conflicts with staff and patients, which in turn was moderated by personal stress reactivity. Physical violence by patients was a pervasive threat for a high proportion of staff. Frequent conflict interactions with volatile patients contributed the most risk, but reactivity to conflict was a dynamic risk factor. The strain associated with assault risk and stress reactivity could be prospectively mitigated by resilience enhancement programming for staff. © 2014 John Wiley & Sons Ltd.

Community awareness is crucial to early detection of breast cancer in low- and middle-income countries. In Ghana 60% of the cases are detected at late stages. Breast Care International (BCI) is a Ghanaian non-governmental organization dedicated to raising breast cancer awareness. A cross-sectional survey was designed to assess the impact of BCI program on knowledge, attitudes and practices (KAP) toward breast cancer among women from rural communities of Ghana. A total of 232 women were interviewed in June 2011 in the Ashanti region; of these 131 participants were from a community that received the BCI program in August 2010 (intervention group) and 101 from another community that received the program post-survey (referent group). Data analysis was performed using Epi-Info version 3.5.3. Knowledge about breast cancer among participants who received the program was better than among those who did not. Only 53.5% of participants from the referent group knew that breast cancer usually appears as painless breast lump when compared to 82.3% from the intervention group. Participants who attended the program were significantly more likely to obtain higher knowledge scores (odds ratio (OR) = 2.10, 95% confidence interval (CI) = 1.14-3.86) and to state practicing breast self-examination (OR = 12.29, 95% CI = 5.31-28.48). The BCI program improved KAP toward breast cancer. Further research is warranted to provide stronger evidence that the program improves breast cancer early detection. © 2013 UICC.

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.

Job Satisfaction of Nurses in a Regional Hospital in Oman: A Cross-Sectional Survey.

PubMed

Al Maqbali, Mohammed Abdullah

2015-09-01

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

Background Despite the growing reputation and subject coverage of the Cochrane Database of Systematic Reviews, many systematic reviews continue to be published solely in paper-based health care journals. This study was designed to determine why authors choose to publish their systematic reviews outside of the Cochrane Collaboration and if they might be interested in converting their reviews to Cochrane format for publication in the Cochrane Database of Systematic Reviews. Methods Cross-sectional survey of Australian primary authors of systematic reviews not published on the Cochrane Database of Systematic Reviews identified from the Database of Abstracts of Reviews of Effectiveness. Results We identified 88 systematic reviews from the Database of Abstracts of Reviews of Effectiveness with an Australian as the primary author. We surveyed 52 authors for whom valid contact information was available. The response rate was 88 per cent (46/52). Ten authors replied without completing the survey, leaving 36 valid surveys for analysis. The most frequently cited reasons for not undertaking a Cochrane review were: lack of time (78%), the need to undergo specific Cochrane training (46%), unwillingness to update reviews (36%), difficulties with the Cochrane process (26%) and the review topic already registered with the Cochrane Collaboration (21%). (Percentages based on completed responses to individual questions.) Nearly half the respondents would consider converting their review to Cochrane format. Dedicated time emerged as the most important factor in facilitating the potential conversion process. Other factors included navigating the Cochrane system, assistance with updating and financial support. Eighty-six per cent were willing to have their review converted to Cochrane format by another author. Conclusion Time required to complete a Cochrane review and the need for specific training are the primary reasons why some authors publish systematic reviews outside of the

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

A cross-sectional survey by anonymous self-assessment questionnaire was given to 3600 high school students from 30 high schools. The purpose of this study was to analyze the prevalence of neck and shoulder pain (NSP) and its effects among high school students in Shanghai, China. NSP has become a problem in many countries in recent years among adolescents. No recent studies have estimated the prevalence of NSP in Chinese school populations. A total of 3600 high school students from all 3 grades chosen from 30 random schools participated in this study. Participants were asked to fill out a questionnaire on NSP and to provide information on demographic items, family factors, schooling, and lifestyles. χ tests were used to compare the incidence of NSP, univariate and multivariate logistic regression analyses were used to obtain influencing factors of NSP. In total, 3600 questionnaires were distributed, and 2842 were valid. The cross-sectional prevalence of NSP was 41.1%, with more girls (653 of 1478, i.e., 44.2%) reporting having NSP than boys (514 of 1364, i.e., 37.7%) (odds ratio = 0.764; 95% confidence interval = 0.657-0.888; P < 0.05). The frequency, duration, and degree of NSP in girls were also higher than in boys. For high school years 1, 2, and 3, the incidence of NSP was 40.1%, 40.7%, and 45.4%, respectively. The multivariate logistic regression indicated that sex, family history of NSP, school furniture, long sitting time, computer use, insufficient rest time, sleep time, commuting method, perceived schoolbag weight, and smoking had a significant effect on NSP. The incidence of NSP in high school students in Shanghai is quite high. The occurrence of NSP is related to several factors including sex and school year, as well as some factors related to family, schooling, and lifestyles. 3.

Distinct minima and maxima in the neutron total cross section uncertainties were observed in model calculations using spherical optical potential. We found this oscillating structure to be a general feature of quantum mechanical wave scattering. Specifically, we analyzed neutron interaction with 56Fe from 1 keV up to 65 MeV, and investigated physical origin of the minima.We discuss their potential importance for practical applications as well as the implications for the uncertainties in total and absorption cross sections.

In 2011, the senior authors were contacted by Ron Gardiner of Questa, and Village of Questa Mayor Esther Garcia, to discuss the existing and future groundwater supply for the Village of Questa. This meeting led to the development of a plan in 2013 to perform an integrated geologic, geophysical, and hydrogeologic investigation of the Questa area by the New Mexico Bureau of Geology & Mineral Resources (NMBG), the U.S. Geological Survey (USGS), and New Mexico Tech (NMT). The NMBG was responsible for the geologic map and geologic cross sections. The USGS was responsible for a detailed geophysical model to be incorporated into the NMBG products. NMT was responsible for providing a graduate student to develop a geochemical and groundwater flow model. This report represents the final products of the geologic and geophysical investigations conducted by the NMBG and USGS. The USGS final products have been incorporated directly into the geologic cross sections. The objective of the study was to characterize and interpret the shallow (to a depth of approximately 5,000 ft) three-dimensional geology and preliminary hydrogeology of the Questa area. The focus of this report is to compile existing geologic and geophysical data, integrate new geophysical data, and interpret these data to construct three, detailed geologic cross sections across the Questa area. These cross sections can be used by the Village of Questa to make decisions about municipal water-well development, and can be used in the future to help in the development of a conceptual model of groundwater flow for the Questa area. Attached to this report are a location map, a preliminary geologic map and unit descriptions, tables of water wells and springs used in the study, and three detailed hydrogeologic cross sections shown at two different vertical scales. The locations of the cross sections are shown on the index map of the cross section sheet.

Osteoarthritis is a leading cause of chronic pain and disability and one of the most common conditions diagnosed and managed in primary care. Despite the evidence that patients would value discussions about the course of osteoarthritis to help them make informed treatment decisions and plan for the future, little is known of GPs' practice of, or views regarding, discussing prognosis with these patients. A cross-sectional postal survey asked 2500 randomly selected UK GPs their views on discussing prognosis with patients with osteoarthritis and potential barriers or facilitators to such discussions. They were also asked if prognostic discussions were part of their current practice and what indicators they considered important in assessing the prognosis associated with osteoarthritis. Of 768 respondents (response rate 30.7 %), the majority felt it necessary to discuss prognosis with osteoarthritis patients (n = 738, 96.1 %), but only two thirds reported that it was part of their routine practice (n = 498, 64.8 %). Most respondents found predicting the course of osteoarthritis (n = 703, 91.8 %) and determining the prognosis of patients difficult (n = 589, 76.7 %). Obesity, level of physical disability and pain severity were considered the most important prognostic indicators in osteoarthritis. Although GPs consider prognostic discussions necessary for patients with osteoarthritis, few prioritise these discussions. Lack of time and perceived difficulties in predicting the disease course and determining prognosis for patients with osteoarthritis may be barriers to engaging in prognostic discussions. Further research is required to identify ways to assist GPs making prognostic predictions for patients with osteoarthritis and facilitate engagement in these discussions.

The absorption cross sections of sodium dimers were studied using a heat pipe over operating in the non-heat-pipe mode. Three wavelength regions were observed. They are in the red, the green-blue, and the near ultraviolet regions. The absorption cross section depends on the wavelength of the incident light. Representative peak values for the v"=0 progression in the red and green-blue regions are 2.59 A sup 2 (average value) and 11.77 A sup 2 (T sub ave=624 K). The value for the C greater than X transitions is several tenths A sup 2. The cross sections were measured from absorption spectra taken as a function of temperature.

Patient-reported outcome measures (PROMs) collected in clinical trials should be administered in a standardised way across sites and routinely screened for avoidable missing data in order to maximise data quality/minimise risk of bias. Recent qualitative findings, however, have raised concerns about the consistency of PROM administration in UK trials. The purpose of this study was to determine the generalisability of these findings across the wider community of trial personnel. Online cross-sectional survey. Participants were recruited from 55 UK Clinical Research Collaboration Registered Clinical Trials Units and 19 Comprehensive Local Research Networks. Research nurses, data managers/coordinators, trial managers and chief/principal investigators involved in clinical trials collecting PROMs. We undertook descriptive analyses of the quantitative data and directed thematic analysis of free-text comments. Factors associated with the management of missing PRO data were explored using logistic regression. Survey data from 767 respondents supported the generalisability of qualitative study findings, suggesting inconsistencies in PROM administration with regard to: the level of assistance given to trial participants; the timing of PROM completion in relation to the clinical consultation; and the management of missing data. Having ≥10 years experience in a research role was significantly associated with the appropriate management of missing PROM data (OR 2.26 (95% CI 1.06 to 4.82), p=0.035). There was a consensus that more PROM guidance was needed in future trials and agreement between professional groups about the necessary components. There are inconsistencies in the way PROMs are administered by trial staff. Such inconsistencies may reduce the quality of data and have the potential to introduce bias. There is a need for improved guidance in future trials that support trial personnel in conducting optimal PROM data collection to inform patient care. Published by the

To assess the prevalence of counterfeit antimalarial drugs in Southeast (SE) Asia. Cross-sectional survey. Pharmacies and shops selling antimalarial drugs in Myanmar (Burma), Lao PDR, Vietnam, Cambodia and Thailand. Proportion of artemisinin derivatives or mefloquine containing drugs of substandard quality. Of the 188 tablet packs purchased which were labelled as 'artesunate' 53% did not contain any artesunate. All counterfeit artesunate tablets were labelled as manufactured by 'Guilin Pharma', and refinements of the fake blisterpacks made them often hard to distinguish from their genuine counterparts. No other artemisinin derivatives were found to be counterfeited. Of the 44 mefloquine samples, 9% contained <10% of the expected amount of active ingredient. An alarmingly high proportion of antimalarial drugs bought in pharmacies and shops in mainland SE Asia are counterfeit, and the problem has increased significantly compared with our previous survey in 1999-2000. This is a serious threat to public health in the region.

To identify the side effects most important to glucocorticoid (GC) users through a survey of a UK online health community (Healthunlocked.com). Online cross-sectional survey. Participants were recruited through Healthunlocked.com, an online social network for health. Adults who were currently taking GCs, or had taken GCs in the past month. Responders scored the importance of listed side effects from 1 to 10, with 10 being of high importance to them. For each side effect, histograms were plotted, and the median rating and IQR were determined. Side effects were ranked by median ranking (largest to smallest) and then IQR (smallest to largest). The scores were categorised as low (scores 1-3), medium (scores 4-7) and high (scores 8-10) importance. 604 responders completed the survey. Histograms of side effect scores showed a skew towards high importance for weight gain, a U-shaped distribution for cardiovascular disease (CVD), diabetes, eye disease and infections, and a skew towards low importance for acne. When ranked, the side effect of most importance to responders was weight gain (median score=9, IQR 6-10) followed by insomnia and moon face with equal median score (8) and IQR (5-10). Three serious side effects, CVD, diabetes and infections, were ranked of lower importance overall but had wide ranging scores (median score=8, IQR 1-10). The three most highly rated side effects were not clinically serious but remained important to patients, perhaps reflecting their impact on quality of life and high prevalence. This should be taken into consideration when discussing treatment options and planning future GC safety studies. Published by the BMJ Publishing Group Limited.

2016-01-01

Background Social media can be used in health care settings to enhance professional networking and education; patient communication, care, and education; public health programs; organizational promotion; and research. Objective The aim of this study was to explore the use of social media networks for the purpose of professional development among health care professionals in Saudi Arabia using a purpose-designed Web-based survey. Methods A cross-sectional web-based survey was undertaken. A link to the survey was posted on the investigator’s personal social media accounts including Twitter, LinkedIn, and WhatsApp. Results A total of 231 health care professionals, who are generally social media users, participated in the study. Of these professionals, 70.6% (163/231) use social media for their professional development. The social media applications most frequently used, in the descending order, for professional development were Twitter, YouTube, Instagram, Facebook, Snapchat, and LinkedIn. The majority of respondents used social media for professional development irrespective of their age group, with the highest proportion seen in those aged 20-30 years. Social media were perceived as being most beneficial for professional development in terms of their impact on the domains of knowledge and problem solving and least helpful for enhancing clinical skills. Twitter was perceived as the most helpful type of social media for all domains listed. Respondents most frequently reported that social media were useful for professional development for the reasons of knowledge exchange and networking. Conclusions Social media are frequently used by health care professionals in Saudi Arabia for the purposes of professional development, with Twitter most frequently used for this purpose. These findings suggest that social media networks can be powerful tools for engaging health care professionals in their professional development. PMID:27731855

Although abortion care has been an established routine since decades in India, 8% of maternal mortality is attributed to unsafe abortion. Increased knowledge and improved attitudes among health care providers have a potential to reduce barriers to safe abortion care by reducing stigma and reluctance to provide abortion. Previous research has shown that medical students' attitudes can predict whether they will perform abortions. The objective of our study was to explore attitudes toward abortion among medical interns in Maharastra, India. A cross-sectional survey was carried out among 1996 medical interns in Maharastra, India. Descriptive and analytical statistics were used to interpret the study instrument. Almost one quarter of the respondents considered abortion to be morally wrong, one fifth did not find abortions for unmarried women acceptable and one quarter falsely believed that a woman needs her partner or spouse's approval to have an abortion. Most participants agreed that unsafe abortion is a serious health problem in India. A majority of the respondents rated their knowledge of sexual and reproductive health as good, but only 13% had any clinical practice in abortion care services. Disallowing attitudes toward abortion and misconceptions about the legal regulations were common among the surveyed medical students. Knowledge and attitudes toward abortion among future physicians could be improved by amendments to the medical education, potentially increasing the number of future providers delivering safe and legal abortion services. Abortion is legal in India since decades, but maternal mortality due to unsafe abortions remains high. This survey of attitudes toward abortion among medical interns in Maharastra indicates that disallowing views prevail. Improved knowledge and clinical training can increase numbers of potential abortion providers, thus limit unsafe abortion. Copyright © 2014 Elsevier Inc. All rights reserved.

The values of ion-atom ionization cross sections are frequently needed for many applications that utilize the propagation of fast ions through matter. When experimental data and theoretical calculations are not available, approximate formulas are frequently used. This paper briefly summarizes the most important theoretical results and approaches to cross section calculations in order to place the discussion in historical perspective and offer a concise introduction to the topic. Based on experimental data and theoretical predictions, a new fit for ionization cross sections is proposed. The range of validity and accuracy of several frequently used approximations (classical trajectory, the Born approximation,more » and so forth) are discussed using, as examples, the ionization cross sections of hydrogen and helium atoms by various fully stripped ions.« less

The Germanwings Flight 9525 crash has brought the sensitive subject of airline pilot mental health to the forefront in aviation. Globally, 350 million people suffer from depression-a common mental disorder. This study provides further information on this important topic regarding mental health especially among female airline pilots. This is the first study to describe airline pilot mental health-with a focus on depression and suicidal thoughts-outside of the information derived from aircraft accident investigations, regulated health examinations, or identifiable self-reports, which are records protected by civil aviation authorities and airline companies. This is a descriptive cross-sectional study via an anonymous web-based survey administered between April and December 2015. Pilots were recruited from unions, airline companies, and airports via convenience sampling. Data analysis included calculating absolute number and prevalence of health characteristics and depression scores. One thousand eight hundred thirty seven (52.7%) of the 3485 surveyed pilots completed the survey, with 1866 (53.5%) completing at least half of the survey. 233 (12.6%) of 1848 airline pilots responding to the Patient Health Questionnaire 9 (PHQ-9), and 193 (13.5%) of 1430 pilots who reported working as an airline pilot in the last seven days at time of survey, met depression threshold-PHQ-9 total score ≥ 10. Seventy-five participants (4.1%) reported having suicidal thoughts within the past two weeks. We found a significant trend in proportions of depression at higher levels of use of sleep-aid medication (trend test z = 6.74, p < 0.001) and among those experiencing sexual harassment (z = 3.18, p = 0.001) or verbal harassment (z = 6.13, p < 0.001). Hundreds of pilots currently flying are managing depressive symptoms perhaps without the possibility of treatment due to the fear of negative career impacts. This study found 233 (12.6%) airline pilots meeting

The integrated approximate cross section itself can be written as the product of an insertion operator (in colour space) times the Born cross section. We give selected results for the insertion operator for processes with two and three hard partons in the final state.

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.

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.

Recruitment to psychiatry is insufficient to meet projected mental health service needs world-wide. We report on the career plans of final year medical students from 20 countries, investigating factors identified from the literature which influence psychiatric career choice. Cross sectional electronic or paper survey. Subjects were final year medical students at 46 medical schools in participating countries. We assessed students' career intentions, motivations, medical school teaching and exposure to psychiatry. We assessed students' attitudes and personality factors. The main outcome measure was likelihood of specializing in psychiatry. Multilevel logistic regression was used to examine the joint effect of factors upon the main outcome. 2198 of 9135 (24%) of students responded (range 4 to 91%) across the countries. Internationally 4.5% of students definitely considered psychiatry as a career (range 1 to 12%). 19% of students (range 0 to 33%) were "quite likely", and 25% were "definitely not" considering psychiatry. Female gender, experience of mental/physical illness, media portrayal of doctors, and positive attitudes to psychiatry, but not personality factors, were associated with choosing psychiatry. Quality of psychiatric placement (correlation coefficient = 0.22, p < 0.001) and number of placements (correlation coefficient =0.21, p < 0.001) were associated with higher ATP scores. During medical school, experience of psychiatric enrichment activities (special studies modules and university psychiatry clubs), experience of acutely unwell patients and perceived clinical responsibility were all associated with choice of psychiatry.Multilevel logistic regression revealed six factors associated with students choosing psychiatry: importance of own vocation, odds ratio (OR) 3.01, 95% CI 1.61 to 5.91, p < 0.001); interest in psychiatry before medical school, OR 10.8 (5.38 to 21.8, p < 0.001); undertaking a psychiatry special study module, OR 1.45 (1.05 to 2.01, p = 0

An accurate knowledge of cross sections for pion production in proton-proton collisions finds wide application in particle physics, astrophysics, cosmic ray physics, and space radiation problems, especially in situations where an incident proton is transported through some medium and knowledge of the output particle spectrum is required when given the input spectrum. In these cases, accurate parameterizations of the cross sections are desired. In this paper much of the experimental data are reviewed and compared with a wide variety of different cross section parameterizations. Therefore, parameterizations of neutral and charged pion cross sections are provided that give a very accurate description of the experimental data. Lorentz invariant differential cross sections, spectral distributions, and total cross section parameterizations are presented.

The intersections between chronicity, disability and social inequality are well understood. Novel ways to counter the social determinants of health and disability are needed. Men's Sheds are a community space where men can participate in a range of shared activities and potentially experience a health and social benefits. This cross-sectional survey was conducted to inform future research by determining who attended Men's Sheds and the range of health, social, community, and educational activities undertaken there. This paper explores the membership of people with disabilities (PWD) at Men's Sheds and the factors that predict their membership. An online survey link was sent to all known Men's Sheds internationally in 2012. Data were analyzed using descriptive and inferential (univariate and multivariate) statistics. 32.2% of international sheds and 29% of Australian sheds specifically targeted the inclusion of PWD. 80% of these sheds have significantly more members with disabilities than sheds who do no target PWD. Factors associated with greater membership of PWD included the provision of transport, social outings and promoting occupational skills. PWD are being encouraged to join and are joining Men's Sheds. This is significant as the value of participation and inclusion toward better health and wellbeing is well known. Men's Sheds offer a community space where the social determinants of chronicity and disability can potentially be countered. Copyright © 2016 Elsevier Inc. All rights reserved.

The experience of having their new-borns admitted to an intensive care unit (NICU) can be extremely distressing. Subsequent risk of post-incident-adjustment difficulties are increased for parents, siblings, and affected families. Patient and next of kin satisfaction surveys provide key indicators of quality in health care. Methodically constructed and validated survey tools are in short supply and parents' experiences of care in Neonatal Intensive Care Units is under-researched. This paper reports a validation of the Neonatal Satisfaction Survey (NSS-8) in six Norwegian NICUs. Parents' survey returns were collected using the Neonatal Satisfaction Survey (NSS-13). Data quality and psychometric properties were systematically assessed using exploratory factor analysis, tests of internal consistency, reliability, construct, convergent and discriminant validity. Each set of hospital returns were subjected to an apostasy analysis before an overall satisfaction rate was calculated. The survey sample of 568 parents represents 45% of total eligible population for the period of the study. Missing data accounted for 1,1% of all returns. Attrition analysis shows congruence between sample and total population. Exploratory factor analysis identified eight factors of concern to parents,"Care and Treatment", "Doctors", "Visits", "Information", "Facilities", "Parents' Anxiety", "Discharge" and "Sibling Visits". All factors showed satisfactory internal consistency, good reliability (Cronbach's alpha ranged from 0.70-0.94). For the whole scale of 51 items α 0.95. Convergent validity using Spearman's rank between the eight factors and question measuring overall satisfaction was significant on all factors. Discriminant validity was established for all factors. Overall satisfaction rates ranged from 86 to 90% while for each of the eight factors measures of satisfaction varied between 64 and 86%. The NSS-8 questionnaire is a valid and reliable scale for measuring parents' assessment of

Cross sections for electron impact excitation of the b 3Sigma(+)u state of H2 - An application of the Schwinger multichannel variational method

In this and the two accompanying letters, the results of calculations of the cross sections for electron impact excitation of the b 3Sigma(+)u state of H2, for collision energies from near threshold to 30 eV, are presented. These results are obtained using a multichannel extension of the Schwinger variational principle at the two-state level. The quantitative agreement between the integral cross sections of these three studies is very good. Inclusion of correlation terms in the scattering wavefunctions, which relax the orthogonality between bound and continuum orbitals, is seen to affect the cross sections substantially. Although a comparison of these calculated cross sections with available experimental data is encouraging, some seious discrepancies exist.

Our prior nuclear absorption cross sections model is extended for light systems (A less than or equal to 4) where either both projectile and target are light particles or one is a light particle and the other is a medium or heavy nucleus. The agreement with experiment is excellent for these cases as well. Present work in combination with our original model provides a comprehensive picture of absorption cross sections for light, medium, and heavy systems, a very valuable input for radiation protection studies.

Using a crossed laser-molecular beam scattering apparatus, these experiments photodissociate ethyl chloride at 193 nm and detect the Cl and ethyl products, resolved by their center-of-mass recoil velocities, with vacuum ultraviolet photoionization. The data determine the relative partial cross-sections for the photoionization of ethyl radicals to form C2H5+, C2H4+, and C2H3+ at 12.1 and 13.8 eV. The data also determine the internal energy distribution of the ethyl radical prior to photoionization, so we can assess the internal energy dependence of the photoionization cross-sections. The results show that the C2H4++H and C2H3++H2 dissociative photoionization cross-sections strongly depend on the photoionization energy. Calibrating the ethyl radical partial photoionization cross-sections relative to the bandwidth-averaged photoionization cross-section of Cl atoms near 13.8 eV allows us to use these data in conjunction with literature estimates of the Cl atom photoionization cross-sections to put the present bandwidth-averaged cross-sections on an absolute scale. The resulting bandwidth-averaged cross-section for the photoionization of ethyl radicals to C2H5+ near 13.8 eV is 8+/-2 Mb. Comparison of our 12.1 eV data with high-resolution ethyl radical photoionization spectra allows us to roughly put the high-resolution spectrum on the same absolute scale. Thus, one obtains the photoionization cross-section of ethyl radicals to C2H5+ from threshold to 12.1 eV. The data show that the onset of the C2H4++H dissociative photoionization channel is above 12.1 eV; this result offers a simple way to determine whether the signal observed in photoionization experiments on complex mixtures is due to ethyl radicals. We discuss an application of the results for resolving the product branching in the O+allyl bimolecular reaction.

DrinkWise Australia is an alcohol industry Social Aspects/Public Relations Organisation (SAPRO). We assessed the Australian public's awareness of DrinkWise, beliefs about its funding source, and associations between funding beliefs and perceptions of DrinkWise. A total of 467 adult weekly drinkers completed an online cross-sectional survey in February 2016. Half the sample had heard of DrinkWise (48.6%); of these, the proportion aware that DrinkWise is industry funded (37.0%) was much smaller than the proportion believing it receives government funding (84.1%). Respondents who incorrectly believed DrinkWise receives government funding were more likely to hold a favourable perception of the organisation's credibility, trustworthiness and respectability than those who did not believe it receives government funding (75.9% vs. 58.3%; p=0.032). The drinking population is vulnerable to believing that alcohol industry public relations organisations such as DrinkWise are government funded, which in turn is associated with more favourable perceptions of the organisation's credibility, trustworthiness, and respectability. Implications for public health: Favourable perceptions of DrinkWise may enhance the industry's ability to delay or dilute potentially effective alcohol control policies. Future research should investigate whether educating the public about DrinkWise's alcohol industry funding alters the public's perception of how credible, trustworthy and respectable the organisation is. © 2017 The Authors.

Objectives The utility value attributed to taking pills for prevention can have a major effect on the cost-effectiveness of interventions, but few published studies have systematically quantified this value. We sought to quantify the utility value of taking pills used for prevention of cardiovascular disease (CVD). Design Cross-sectional survey. Setting Central North Carolina. Participants 708 healthcare employees aged 18 years and older. Primary and secondary outcomes Utility values for taking 1 pill/day, assessed using time trade-off, modified standard gamble and willingness-to-pay methods. Results Mean age of respondents was 43 years (19–74). The majority of the respondents were female (83%) and Caucasian (80%). Most (80%) took at least 2 pills/day. Mean utility values for taking 1 pill/day using the time trade-off method were: 0.9972 (95% CI 0.9962 to 0.9980). Values derived from the standard gamble and willingness-to-pay methods were 0.9967 (0.9954 to 0.9979) and 0.9989 (95% CI 0.9986 to 0.9991), respectively. Utility values varied little across characteristics such as age, sex, race, education level or number of pills taken per day. Conclusions The utility value of taking pills daily in order to prevent an adverse CVD health outcome is approximately 0.997. PMID:25967985

School dropout in adolescents can have negative consequences, not only for the individual and the family, but also for the society. To identify the characteristics associated with the occurrence of this event might contribute to the planning of a prevention strategy. To evaluate the relationship between the individual and home characteristics and school dropout in adolescents from 12 to 17 years old in Colombia. A cross sectional study was conducted from information taken from the results obtained in the 2015 National Mental Health Survey. A study was made of the relationship between the individual and home characteristics and school dropout in adolescents from 12 to 17 years old RESULTS: A higher percentage of school dropouts was found in the older adolescents, females, and those who have children. Among the home characteristics, it was observed that those homes with more than two people, located in rural area, or that are classified as poor, have an increased percentage of school dropout adolescents. Strategies for which the main goal is to prevent school dropout should consider populations with higher prevalence of out-of-school adolescents (female, homes in rural area, or household poverty). Preventive actions of adolescent pregnancy might contribute to reduce the school dropout rate. Copyright © 2016 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

Ineffective coping may lead to impaired job performance and burnout, with adverse consequences to staff well-being and patient outcomes. We examined the relationship between coping styles and burnout in emergency physicians, nurses and support staff at seven small, medium and large emergency departments (ED) in a Canadian health region (population 500,000). Linear regression with the Coping Inventory for Stressful Situations (CISS) and Maslach Burnout Inventory (MBI) was used to evaluate the effect of coping style on levels of burnout in a cross-sectional survey of 616 ED staff members. CISS measures coping style in three categories: task-oriented, emotion-oriented and avoidance-oriented coping; MBI, in use for 30 years, assesses the level of burnout in healthcare workers. Task-oriented coping was associated with decreased risk of burnout, while emotion-oriented coping was associated with increased risk of burnout. Specific coping styles are associated with varied risk of burnout in ED staff across several different types of hospitals in a regional network. Coping style intervention may reduce burnout, while leading to improvement in staff well-being and patient outcomes. Further studies should focus on building and sustaining task-oriented coping, along with alternatives to emotion-oriented coping. Published by the BMJ Publishing Group Limited.

This study explored current physiotherapy practice trends for management of children who are overweight or obese. The professional needs of physiotherapists working with this population were also assessed, including the perceived need for physiotherapy clinical guidelines for prevention and management of children with obesity. A cross-sectional survey design was used, with questionnaires purposefully distributed through 13 key physiotherapy services throughout Australia. Snowball sampling resulted in completed questionnaires from 64 physiotherapists who provided services to children. Half (n=33, 52%) of respondents provided services specifically to overweight or obese children. Of those providing services, one-quarter had prior training specific to working with this population. Most used multi-disciplinary models (n=16, 76%) and provided under 5h of obesity-related services each week (n=29, 88%). Half (n=16, 49%) used body mass index as an outcome measure but more (n=25, 76%) used bodyweight. Only 14 (42%) assessed motor skills. The majority of respondents (n=57, 89%) indicated a need for physiotherapy guidelines to best manage overweight and obese children. Professional development priorities included: 'Educating children and families', 'Assessment methods' and 'Exercise prescription' for overweight and obese children. This data provides workforce intelligence to guide future professional training and inform development of clinical guidelines for physiotherapists in prevention and management of children with obesity and related chronic disease.

Dijet production by almost real photons has been studied at HERA with the ZEUS detector. Jets have been identified using the cone algorithm. A cut on xγOBS, the fraction of the photon energy participating in the production of the two jets of highest transverse energy, is used to define cross sections sensitive to the parton distributions in the proton and in the photon. The dependence of the dijet cross sections on pseudorapidity has been measured for xγOBS ⩾ 0.75 and xγOBS < 0.75. The former is sensitive to the gluon momentum density in the proton. The latter is sensitive to the ginon in the photon. The cross sections are corrected for detector acceptance and compared to leading order QCD calculations.

Cross-sectional structural parameters from densitometry

Cleek, Tammy M.; Whalen, Robert T.

Bone densitometry has previously been used to obtain cross-sectional properties of bone from a single X-ray projection across the bone width. Using three unique projections, we have extended the method to obtain the principal area moments of inertia and orientations of the principal axes at each scan cross-section along the length of the scan. Various aluminum phantoms were used to examine scanner characteristics to develop the highest accuracy possible for in vitro non-invasive analysis of cross-sectional properties. Factors considered included X-ray photon energy, initial scan orientation, the angle spanned by the three scans (included angle), and I(min)/I(max) ratios. Principal moments of inertia were accurate to within +/-3.1% and principal angles were within +/-1 degrees of the expected value for phantoms scanned with included angles of 60 degrees and 90 degrees at the higher X-ray photon energy (140 kVp). Low standard deviations in the error (0.68-1.84%) also indicate high precision of calculated measurements with these included angles. Accuracy and precision decreased slightly when the included angle was reduced to 30 degrees. The method was then successfully applied to a pair of excised cadaveric tibiae. The accuracy and insensitivity of the algorithms to cross-sectional shape and changing isotropy (I(min)/I(max)) values when various included angles are used make this technique viable for future in vivo studies.

Women's and men's negative experience of child birth-A cross-sectional survey.

PubMed

Nystedt, Astrid; Hildingsson, Ingegerd

2018-04-01

A negative birth experience may influence both women and men and can limit their process of becoming a parent. This study aimed to analyze and describe women's and men's perceptions and experiences of childbirth. A cross-sectional study of women and their partners living in one Swedish county were recruited in mid pregnancy and followed up two months after birth. Women (n=928) and men (n=818) completed the same questionnaire that investigated new parents' birth experiences in relation to socio-demographic background and birth related variables. Women (6%) and men (3%) with a negative birth experiences, experienced longer labours and more often emergency caesarean section compared to women (94%) and men (97%) with a positive birth experience. The obstetric factors that contributed most strongly to a negative birth experience were emergency caesarean and was found in women (OR 4.7, 95% CI 2.0-10.8) and men (OR 4.5, Cl 95% 1.4-17.3). In addition, pain intensity and elective caesarean section were also associated with a negative birth experiences in women. Feelings during birth such as agreeing with the statement; 'It was a pain to give birth' were a strong contributing factor for both women and men. A negative birth experience is associated with obstetric factors such as emergency caesarean section and negative feelings. The content of negative feelings differed between women and men. It is important to take into account that their feelings differ in order to facilitate the processing of the negative birth experience for both partners.

Socially withdrawn youth belong to an emerging subgroup of youth who are not in employment, education, or training and who have limited social interaction intention and opportunities. The use of the internet and social media is expected to be an alternative and feasible way to reach this group of young people because of their reclusive nature. The aim of this study was to explore the possibility of using various social media platforms to investigate the existence of the phenomenon of youth social withdrawal in 3 major cities in China. A cross-sectional open Web survey was conducted from October 2015 to May 2016 to identify and reach socially withdrawn youth in 3 metropolitan cities in China: Beijing, Shanghai, and Shenzhen. To advertise the survey, 3 social media platforms were used: Weibo, WeChat, and Wandianba, a social networking gaming website. In total, 137 participants completed the survey, among whom 13 (9.5%) were identified as belonging to the withdrawal group, 7 (5.1%) to the asocial group, and 9 (6.6%) to the hikikomori group (both withdrawn and asocial for more than 3 months). The cost of recruitment via Weibo was US $7.27 per participant. Several social media platforms in China are viable and inexpensive tools to reach socially withdrawn youth, and internet platforms that specialize in a certain culture or type of entertainment appeared to be more effective in reaching socially withdrawn youth. ©Lucia Lin Liu, Tim MH Li, Alan R Teo, Takahiro A Kato, Paul WC Wong.

Setting 32 hospital units in 19 Norwegian hospitals with electronic medical records systems. Participants 227 (72%) of 314 hospital doctors responded, equally distributed between the three electronic medical records systems. Main outcome measures Proportion of respondents who used the electronic system, calculated for each of 23 tasks; difference in proportions of users of different systems when functionality of systems was similar. Results Most tasks listed in the questionnaire (15/23) were generally covered with implemented functions in the electronic medical records systems. However, the systems were used for only 2-7 of the tasks, mainly associated with reading patient data. Respondents showed significant differences in frequency of use of the different systems for four tasks for which the systems offered equivalent functionality. The respondents scored highly in computer literacy (72.2/100), and computer use showed no correlation with respondents' age, sex, or work position. User satisfaction scores were generally positive (67.2/100), with some difference between the systems. Conclusions Doctors used electronic medical records systems for far fewer tasks than the systems supported. What is already known on this topicElectronic information systems in health care have not undergone systematic evaluation, and few comparisons between electronic medical records systems have been madeGiven the information intensive nature of clinical work, electronic medical records systems should be of help to doctors for most clinical tasksWhat this study addsDoctors in Norwegian hospitals reported a low level of use of all electronic medical records systems

Despite the rapid growth of Chinese nursing PhD programs, little is known about the career intentions of students in this field. To investigate the career intentions of nursing PhD students. Online cross-sectional survey. Nursing PhD students at Chinese universities. An online questionnaire was designed and the data were analyzed using SPSS. The mean age of the participants was 31.53 ± 4.92 years, and most were female (89.9%), married (74.2%), and had been employed previously (69.7%). Most intended to work in the city where their family lived (34.8%) or near their previous workplace (32.6%). Most (60.7%) desired to work in an educational institution (e.g., a university or college). The most common expected salary was 8000-11,999 RMB/month. The work benefits perceived as indispensable were "Five Insurances and One Fund" (77.5%), good educational resources for children (59.6%), financial allowances for PhD graduates (52.8%), staff dormitories/housing subsidies (50.6%), and tenure (50.6%). Nursing education (75.3%) and research (70.8%) were the most favored fields. The key job characteristics were the opportunity to put strengths to fullest use (79.8%), time to conduct research (60.7%), and work-life balance (51.7%). The key research conditions included a good research incentive mechanism (77.5%), a Basic Scientific Research Foundation (68.5%), opportunity to apply to conduct research projects (66.3%), and the nursing team's atmosphere regarding research (64.0%), and 91.0% were eager to study abroad (e.g., as part of an international exchange). Nursing PhD students would like to work in their hometown or near their previous workplace. Most preferred working in an educational institution, and the most popular fields were nursing education and research (rather than clinical care), despite the high demand of hospital management for nursing PhD graduates. Flexible work, high-quality research conditions, a certain salary, work benefits, and training were key

The present paper reports electron impact total inelastic and ionization cross section for silicon, germanium, and tin tetrahalides at energies varying from ionization threshold of the target to 5000 eV. These cross section data over a wide energy domain are very essential to understand the physico-chemical processes involved in various environments such as plasma modeling, semiconductor etching, atmospheric sciences, biological sciences, and radiation physics. However, the cross section data on the above mentioned molecules are scarce. In the present article, we report the computation of total inelastic cross section using spherical complex optical potential formalism and the estimation of ionization cross section through a semi-empirical method. The present ionization cross section result obtained for SiCl4 shows excellent agreement with previous measurements, while other molecules have not yet been investigated experimentally. Present results show more consistent behaviour than previous theoretical estimates. Besides cross sections, we have also studied the correlation of maximum ionization cross section with the square root of the ratio of polarizability to ionization potential for the molecules with known polarizabilities. A linear relation is observed between these quantities. This correlation is used to obtain approximate polarizability volumes for SiBr4, SiI4, GeCl4, GeBr4, and GeI4 molecules.

1993-01-01

The temperature dependence of the HNO3 absorption cross sections between 240 and 360 K over the wavelength range 195 to 350 nm has been measured using a diode array spectrometer. Absorption cross sections were determined using both (1) absolute pressure measurements at 298 K and (2) a dual absorption cell arrangement in which the absorption spectrum at various temperatures is measured relative to the room temperature absorption spectrum. The HNO3 absorption spectrum showed a temperature dependence which is weak at short wavelengths but stronger at longer wavelengths which are important for photolysis in the lower stratosphere. The 298 K absorption cross sections were found to be larger than the values currently recommended for atmospheric modeling (DeMore et al., 1992). Our absorption cross section data are critically compared with the previous measurements of both room temperature and temperature-dependent absorption cross sections. Temperature-dependent absorption cross sections of HNO3 are recommended for use in atmospheric modeling. These temperature dependent HNO3 absorption cross sections were used in a two-dimensional dynamical-photochemical model to demonstrate the effects of the revised absorption cross sections on loss rate of HNO3 and the abundance of NO2 in the stratosphere.

Positron induced scattering cross sections for hydrocarbons relevant to plasma

Singh, Suvam; Antony, Bobby

2018-05-01

This article explores positron scattering cross sections by simple hydrocarbons such as ethane, ethene, ethyne, propane, and propyne. Chemical erosion processes occurring on the surface due to plasma-wall interactions are an abundant source of hydrocarbon molecules which contaminate the hydrogenic plasma. These hydrocarbons play an important role in the edge plasma region of Tokamak and ITER. In addition to this, they are also one of the major components in the planetary atmospheres and astrophysical mediums. The present work focuses on calculation of different positron impact interactions with simple hydrocarbons in terms of the total cross section (Qtot), elastic cross section (Qel), direct ionization cross section (Qion), positronium formation cross section (Qps), and total ionization cross section (Qtion). Knowing that the positron-plasma study is one of the trending fields, the calculated data have diverse plasma and astrophysical modeling applications. A comprehensive study of Qtot has been provided where the inelastic cross sections have been reported for the first time. Comparisons are made with those available from the literature, and a good agreement is obtained with the measurements.

Decision makers are searching for models to redesign home care and to organize health care in a more sustainable way. The aim of this study is to identify and characterize home care models within and across European countries by means of structural characteristics and care processes at the policy and the organization level. At the policy level, variables that reflected variation in health care policy were included based on a literature review on the home care policy for older persons in six European countries: Belgium, Finland, Germany, Iceland, Italy, and the Netherlands. At the organizational level, data on the structural characteristics and the care processes were collected from 36 home care organizations by means of a survey. Data were collected between 2013 and 2015 during the IBenC project. An observational, cross sectional, quantitative design was used. The analyses consisted of a principal component analysis followed by a hierarchical cluster analysis. Fifteen variables at the organizational level, spread across three components, explained 75.4% of the total variance. The three components made it possible to distribute home care organizations into six care models that differ on the level of patient-centered care delivery, the availability of specialized care professionals, and the level of monitoring care performance. Policy level variables did not contribute to distinguishing between home care models. Six home care models were identified and characterized. These models can be used to describe best practices.

SU-E-I-43: Photoelectric Cross Section Revisited

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

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

Neutrino-nucleus cross sections for oscillation experiments

Katori, Teppei; Martini, Marco

2018-01-01

Neutrino oscillations physics is entering an era of high precision. In this context, accelerator-based neutrino experiments need a reduction in systematic errors to the level of a few percent. Today, one of the most important sources of systematic errors are neutrino-nucleus cross sections which, in the energy region of hundreds of MeV to a few GeV, are known to a precision not exceeding 20%. In this article we review the present experimental and theoretical knowledge of neutrino-nucleus interaction physics. After introducing neutrino-oscillation physics and accelerator-based neutrino experiments, we give an overview of general aspects of neutrino-nucleus cross sections, from both the theoretical and experimental point of view. Then, we focus on these cross sections in different reaction channels. We start with the quasi-elastic and quasi-elastic-like cross section, placing a special emphasis on the multinucleon emission channel, which has attracted a lot of attention in the last few years. We review the main aspects of the different microscopic models for this channel by discussing analogies and the differences among them. The discussion is always driven by a comparison with the experimental data. We then consider the one-pion production channel where agreement between data and theory remains highly unsatisfactory. We describe how to interpret pion data, and then analyze, in particular, the puzzle related to the difficulty of theoretical models and Monte Carlo to simultaneously describe MiniBooNE and MINERvA experimental results. Inclusive cross sections are also discussed, as well as the comparison between the {ν }μ and {ν }e cross sections, relevant for the charge-conjugation-parity violation experiments. The impact of nuclear effects on the reconstruction of neutrino energy and on the determination of the neutrino-oscillation parameters is also reviewed. Finally, we look to the future by discussing projects and efforts in relation to future detectors, beams

Inclined Bodies of Various Cross Sections at Supersonic Speeds

To aid in assessing effects of cross-sectional shape on body aerodynamics, the forces and moments have been measured for bodies with circular, elliptic, square, and triangular cross sections at Mach numbers 1.98 and 3.88. Results for bodies with noncircular cross sections have been compared with results for bodies of revolution having the same axial distribution of cross-sectional area (and, thus, the same equivalent fineness ratio). Comparisons have been made for bodies of fineness ratios 6 and 10 at angles of attack from 0 deg to about 20 deg and for Reynolds numbers, based on body length, of 4.0 x 10(exp 6) and 6.7 x 10(exp 6). The results of this investigation show that distinct aerodynamic advantages can be obtained by using bodies with noncircular cross sections. At certain angles of bank, bodies with elliptic, square, and triangular cross sections develop considerably greater lift and lift-drag ratios than equivalent bodies of revolution. For bodies with elliptic cross sections, lift and pitching-moment coefficients can be correlated with corresponding coefficients for equivalent circular bodies. It has been found that the ratios of lift and pitching-moment coefficients for an elliptic body to those for an equivalent circular body are practically constant with change in both angle of attack and Mach number. These lift and moment ratios are given very accurately by slender-body theory. As a result of this agreement, the method of NACA Rep. 1048 for computing forces and moments for bodies of revolution has been simply extended to bodies with elliptic cross sections. For the cases considered (elliptic bodies of fineness ratios 6 and 10 having cross-sectional axis ratios of 1.5 and 2), agreement of theory with experiment is very good. As a supplement to the force and moment results, visual studies of the flow over bodies have been made by use of the vapor-screen, sublimation, and white-lead techniques. Photographs from these studies are included in the report.

As international development partners reduce funding for family planning (FP) programs, the need to estimate the financial resources devoted to FP is becoming increasingly important both at all levels. This cross-sectional assessment examined the FP financing sources, agents, and expenditures in two counties of Kenya for fiscal years 2010/2011 and 2011/2012 to guide local decision-making on financial allocations. Data were collected through a participatory process. This involved stakeholder interviews, review of financial records and service statistics, and a survey of facilities offering FP services. Financing sources and agents were identified, and source amounts calculated. Types of FP provider organizations and the amounts spent by expenditure categories were identified. Overall, five financing sources and seven agents for FP were identified. Total two-year expenditures were KSh 307.8 M (US$ 3.62 M). The government's share of funding rose from 12% to 21% over the two years (p=0.029). In 2010/2011, the largest expense categories were administration, commodities, and labor; however, spending on commodities increased by 47% (p=0.042). This study provides local managers with FP financing and expenditure information for use in budget allocation decision-making. These analyses can be done routinely and replicated in other local counties or countries in a context of devolution.

Background Rural-to-urban migrant women may be vulnerable to smoking initiation as they are newly exposed to risk factors in the urban environment. We sought to identify correlates of smoking among rural-to-urban migrant women in China. Methods/Principal Findings A cross-sectional survey of rural-to-urban migrant women working in restaurants and hotels (RHW) and those working as commercial sex workers (CSW) was conducted in ten provincial capital cities in China. Multiple logistic regression was conducted to identify correlates of smoking. We enrolled 2229 rural-to-urban migrant women (1697 RHWs aged 18–24 years and 532 CSWs aged 18–30 years). Of these, 18.4% RHWs and 58.3% CSWs reported ever tried smoking and 3.2% RHWs and 41.9% CSWs reported current smoking. Participants who first tried smoking after moving to the city were more likely to be current smokers compared to participants who first tried smoking before moving to the city (25.3% vs. 13.8% among RHWs, p = 0.02; 83.6% vs. 58.6% among CSWs, p = <0.01). Adjusting for other factors, “tried female cigarette brands” had the strongest association with current smoking (OR 5.69, 95%CI 3.44 to 9.41) among participants who had ever tried smoking. Conclusions/Significance Exposure to female cigarette brands may increase the susceptibility to smoking among rural-to-urban migrant women. Smoke-free policies and increased taxes may be effective in preventing rural-to-urban migrant women from smoking initiation. PMID:21829683

Background The demographics and lifestyles of Canadians are changing, thereby influencing food choices and food preparation in the home. Although different dietary practices are associated with increased risk of foodborne illness, our ability to evaluate food consumption trends and assess risks associated with foodborne illness is limited by lack of data on current eating habits and consumer food safety practices. The objective of this study was to describe, for the first time, the food consumption patterns in a Canadian-based population from a food safety perspective, in order to establish baseline data on actual food intake of individuals. Method A cross-sectional telephone survey of 2,332 randomly selected residents of Waterloo Region, Ontario, Canada (C-EnterNet pilot site) was conducted between November 2005 and March 2006. Food intake was assessed using a 7-day dietary recall method. Results Certain food items were consumed more than others among the same food groups, and consumption of many food items varied by gender and age. Specific foods considered high-risk for the transmission of certain enteric pathogens were significantly more likely to be consumed by males (i.e. unpasteurized juice, bean sprouts, and undercooked meat) and elderly individuals (i.e. undercooked eggs). The majority of households prepared and consumed most meals at home, allocating an average of 44 minutes to prepare a meal. Conclusion Baseline data on actual food intake is useful to public health professionals and food safety risk assessors for developing communication messages to consumers and in foodborne outbreak investigations.

The degree of thromboprophylaxis in medical outpatients is low despite a substantial risk for venous thromboembolism (VTE). This may be attributable to difficulties in assessing risk. Assessment tools like the Haas' scorecard aid in determining the need for thromboprophylaxis. We aimed at evaluating how the use of this tool may aid physicians in appropriately using anticoagulants. This was an epidemiological, cross-sectional survey of acute medically ill patients with limited mobility treated by general practitioners and internists. Risk assessment for VTE by the treating physician was compared to calculated risk. Of 8,123 patients evaluated between August 2006 and April 2008, 7,271 fulfilled the in- and exclusion criteria. Mean age was 69.4 ± 13.6 years, and 45.2% were male. Of these 82.8% were high risk based on their acute medical condition, 37.9% based on their underlying chronic condition. Immobilisation, heart failure, pneumonia, age, obesity, and major varicosis were the most frequently encountered risk factors. The agreement between the Haas' scorecard and physician indicated risk was high. At least 94.1% of patients with high risk received adequate anticoagulation mostly as low molecular weight heparins for a mean duration of 15.1 ± 30.5 days. There is a substantial risk for VTE in medical outpatients. Using a simple structured scorecard resulted in an overall appropriate risk assessment and high degree of anticoagulation. The scorecard may provide a tool to improve the overall awareness for VTE risk in medical outpatients, substantially improving the degree of prophylaxis in a patient population with largely underestimated risk.

Objective Little evidence, other than that commissioned by the tobacco industry, exists on the size of the illicit tobacco trade. This study addresses this gap by examining the level and nature of illicit cigarettes and hand-rolled tobacco in 18 European countries. Design Face-to-face cross-sectional survey on smoking. Setting 18 European countries. Participants For each country, around 1000 subjects representative of the population aged 15 and over were enrolled. Current cigarette smokers were asked to show their latest purchased pack of cigarettes or hand-rolled tobacco. Main outcome measure A comprehensive measure called Identification of an Illicit Pack (IIP) was used to study the extent of illicit trade, defining a pack as illicit if it had at least one of the following tax evasion indicators: 1) it was bought from illicit sources, as reported by smokers, 2) it had an inappropriate tax stamp, 3) it had an inappropriate health warning, 4) its price was substantially below the known price in their market. Results Overall, the proportion of illicit packs was 6.5%. The highest prevalence of IIP was observed in Latvia (37.8%). Illicit packs were more frequent among less educated smokers and among those living in a country, which shared a land or sea border with Ukraine, Russia, Moldova or Belarus. No significant association was found with price of cigarettes. Conclusion this study indicates that IIP is less than 7% in Europe, and suggests that the supply of illicit tobacco, rather than its price, is a key factor contributing to tax evasion. PMID:23233420

Little evidence exists on the burden that chronic heart failure (HF) poses specifically to patients in China. The objective of this study, therefore, was to describe the burden of HF on patients in China. A cross-sectional survey of cardiologists and their patients with HF was conducted. Patient record forms were completed by 150 cardiologists for 10 consecutive patients. Patients for whom a patient record form was completed were invited to complete a patient questionnaire. Most of the 933 patients (mean [SD] age 65.8 [10.2] years; 55% male; 80% retired) included in the study received care in tier 2 and 3 hospitals in large cities. Patients gave a median score of 4 on a scale from 1 (no disruption) to 10 (severe disruption) to describe how much HF disrupts their everyday life. Patients in paid employment (8%) missed 10% of work time and experienced 29% impairment in their ability to work due to HF in the previous week. All aspects of patients' health-related quality of life (QoL) were negatively affected by their condition. Mean ± SD utility calculated by the 3-level 5-dimension EuroQol questionnaire was 0.8±0.2, and patients rated their health at 70.3 (11.5) on a 100 mm visual analog scale. Patients incurred costs associated with HF treatment, travel, and professional caregiving services. HF is associated with poor health-related QoL and considerable disruption in patients' lives. Novel and improved therapies are needed to reduce the burden of HF on patients and the health care system.

It has long been recognized that galactic cosmic rays are of such high energy that they tend to pass through available shielding materials resulting in exposure of astronauts and equipment within space vehicles and habitats. Any protection provided by shielding materials result not so much from stopping such particles but by changing their physical character in interaction with shielding material nuclei forming, hopefully, less dangerous species. Clearly, the fidelity of the nuclear cross-sections is essential to correct specification of shield design and sensitivity to cross-section error is important in guiding experimental validation of cross-section models and database. We examine the Boltzmann transport equation which is used to calculate dose equivalent during solar minimum, with units (cSv/yr), associated with various depths of shielding materials. The dose equivalent is a weighted sum of contributions from neutrons, protons, light ions, medium ions and heavy ions. We investigate the sensitivity of dose equivalent calculations due to errors in nuclear fragmentation cross-sections. We do this error analysis for all possible projectile-fragment combinations (14,365 such combinations) to estimate the sensitivity of the shielding calculations to errors in the nuclear fragmentation cross-sections. Numerical differentiation with respect to the cross-sections will be evaluated in a broad class of materials including polyethylene, aluminum and copper. We will identify the most important cross-sections for further experimental study and evaluate their impact on propagated errors in shielding estimates.

The effect of identification of the partial wave parameter of the J/sub z/ CCS and IOS approximations as an orbital angular momentum rather than the total angular momentum is studied. Comparison with accurate close coupling calculations for Ar--N/sub 2/ and He--CO/sub 2/ collisions is made, and it is found that this identification results in a marked improvement, both quantitative and qualitative, in calculated IOS opacity functions and integral cross sections for both elastic and inelastic collisions. Use of the correct energy in the cross section formula also makes a marked improvement even though T matrices are computed with an averagemore » energy. (AIP)« less

Codeine misuse and dependence poses a clinical and public health challenge. However, little is known about dependence and treatment needs in the UK and Ireland. To characterize codeine use, dependence and help-seeking behaviour. An online cross-sectional survey advertised on Facebook, Twitter, health and drug websites and e-mail circulars. The survey collected data on demographics and codeine use amongst adults from the UK and Ireland. The Severity of Dependence Scale measured the level of codeine dependence. The sample of 316 respondents had a mean age of 35.3 years (SD = 12.3) and 67% were women. Of the 316 respondents, 54 scored ≥5 on the Severity of Dependence Scale indicating codeine dependence (17.1%). Our study found that codeine dependence is a problem with both prescribed and 'over-the-counter' codeine. Codeine dependence was associated with daily use of codeine, faking or exaggerating symptoms to get a prescription for codeine and 'pharmacy shopping' ( P < 0.01). A higher number of respondents had sought advice on the Internet (12%) rather than from their general medical practitioner (GP) (5.4%). Less than 1% of respondents had sought advice from a pharmacist. Codeine dependent users were more likely to seek help on the Internet to control their use of codeine than from a GP, which may indicate a potential for greater specialized addiction treatment demand through increased identification and referrals in primary care. © The Author 2017.

2012-01-01

Supplementation of conventional medicines with herbs is increasing globally, including among people infected with HIV. Yet there is little data systematically describing the prevalence and patterns of this supplementation and on which counseling scripts can be based. Moringa oleifera is an herb found in the tropics and sub-tropics commonly used for medicinal and nutritional purposes. This survey determined the prevalence and patterns of use of M. oleifera among HIV positive patients. The study was a cross-sectional survey. HIV-infected adults were enrolled from an opportunistic infections clinic of a referral hospital. Using a previously piloted researcher administered questionnaire; patients who reported to the clinic over three months were interviewed about their use of herbal medicines. The focus was on M. oleifera use, and included plant part, dosage, prescribers and the associated medical conditions. Sixty-eight percent (68%) of the study participants consumed M. oleifera. Of these, 81% had commenced antiretroviral drugs. Friends or relatives were the most common source of a recommendation for use of the herb (69%). Most (80%) consumed M. oleifera to boost the immune system. The leaf powder was mainly used, either alone or in combination with the root and/or bark. M. oleifera supplementation is common among HIV positive people. Because it is frequently prescribed by non-professionals and taken concomitantly with conventional medicine, it poses a potential risk for herb-drug interactions. Further experimental investigations into its effect on drug metabolism and transport would be useful in improving clinical outcome of HIV positive patients. PMID:28239440

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.

Infant feeding practices in Bhaktapur, Nepal: a cross-sectional, health facility based survey

PubMed Central

2012-01-01

Background Promotion of proper breastfeeding practices for the first six months of life is the most cost-effective intervention for reducing childhood morbidity and mortality. However, the adherence to breastfeeding recommendations in many developing countries is not satisfactory. The aims of the study were to determine breastfeeding and infant feeding patterns at nine months of age and to assess factors influencing exclusive breastfeeding practices. Methods In Bhaktapur, Nepal, we carried out a cross-sectional survey of 325 infants who came for measles vaccination at the age of nine months. Mothers were interviewed on details regarding feeding of their child and health since birth. Results Three quarters of all mothers reported that they did not receive any information on breastfeeding during the antenatal visit. Two hundred and ninety five (91%) mothers gave colostrum and 185 (57%) initiated breastfeeding within one hour of delivery. The prevalence of exclusively breastfeeding at 1, 3 and 6 months were 240 (74%), 78 (24%) and 29 (9%), and partial feeding was initiated in 49 (15%), 124 (38%) and 257 (79%) babies, respectively. The main reason, according to the mother, for introducing other foods before six months of age was insufficient breast milk. In logistic regression analyses, mother's knowledge on how long child should be given only breast milk and not living in joint families were associated positively with exclusive or predominant breastfeeding for four months or beyond. Conclusions Despite the high proportion of mothers who initiated breastfeeding immediately after birth, continuation of exclusive breastfeeding for up to six months was not common. Very few mothers received any information on breastfeeding during the antenatal visit, indicating a need for counseling on exclusive breastfeeding. Possible options for this counseling could be during antenatal visits and at regular clinic visits for vaccination. PMID:22230510

Nonadherence to antihypertensive medicines limits their effectiveness, increases the risk of adverse health outcome, and is associated with significant health care costs. The multiple causes of nonadherence differ both within and between patients and are influenced by patients' care settings. The objective of this article was to identify determinants of patient nonadherence to antihypertensive medicines, drawing from psychosocial and economic models of behavior. Outpatients with hypertension from Austria, Belgium, England, Germany, Greece, Hungary, The Netherlands, Poland, and Wales were recruited to a cross-sectional online survey. Nonadherence to medicines was assessed using the Morisky Medication Adherence Scale (primary outcome) and the Medication Adherence Rating Scale. Associations with adherence and nonadherence were tested for demographic, clinical, and psychosocial factors. A total of 2595 patients completed the questionnaire. The percentage of patients classed as nonadherent ranged from 24% in The Netherlands to 70% in Hungary. Low age, low self-efficacy, and respondents' perceptions of their illness and cost-related barriers were associated with nonadherence measured on the Morisky Medication Adherence Scale across several countries. In multilevel, multivariate analysis, low self-efficacy (odds ratio = 0.73; 95% confidence interval 0.70-0.77) and a high number of perceived barriers to taking medicines (odds ratio = 1.70; 95% confidence interval 1.38-2.09) were the main significant determinants of nonadherence. Country differences explained 11% of the variance in nonadherence. Among the variables measured, patients' adherence to antihypertensive medicines is influenced primarily by their self-efficacy, illness beliefs, and perceived barriers. These should be targets for interventions for improving adherence, as should an appreciation of differences among the countries in which they are being delivered.

BACKGROUND: Young adults, especially men, are among those least likely to consult healthcare professionals when mentally distressed or suicidal. AIMS: To investigate the help-seeking behaviours of mentally distressed young adults. Design of study: Cross-sectional survey. SETTING: Bristol and surrounding areas, including inner-city, suburban and urban locations. METHOD: A questionnaire was sent to a sample of 3004 young adults aged 16-24 years. This assessed probable mental disorder (using the 12-item general health questionnaire [GHQ-12]), suicidal thoughts (GHQ-28 suicide subscale), and help-seeking behaviours. RESULTS: Most responders who were assessed as having probable mental disorders (GHQ "cases") had not sought help. Help seeking was more common in female GHQ cases than male cases (34.8% and 21.8%,respectively; P = 0.003) and women with suicidal thoughts more commonly sought help than men with suicidal thoughts (41.6% and 30.9%, respectively; P = 0.15). Small proportions of male and female GHQ cases (7.5% and 8.9%, respectively; P = 0.6), and less than one in five responders with suicidal thoughts, had consulted a general practitioner. In more female than male cases, help was sought from family and friends (30.7% and 18.4%, respectively; P = 0.004). GHQ score was the strongest predictor of help seeking. Men had a higher threshold of severity at which they would seek help than women. Recent experience of suicidal thoughts appeared to be a stronger predictor of formal help seeking in mentally distressed women than mentally distressed men. CONCLUSION: Distressed young adults are reluctant to seek help. Men are particularly unlikely to do so unless severely distressed and tend not to seek lay support. Sex differences in help seeking may be important in understanding the high suicide rate for men. PMID:15113490

Compassion satisfaction and compassion fatigue influence nurses' intention to stay or leave nursing. Identification of compassion satisfaction or fatigue in critical care nurses is important in this high turnover workforce. The aim of this study was to examine factors predicting and contributing to compassion satisfaction and compassion fatigue experienced by critical care nurses in Australian intensive care units. A self-reported cross-sectional survey using an established tool collected data from critical care nurses of two adult Australian intensive care units. Overall, these critical care nurses reported what Professional Quality of Life Scale guidelines designated as 'average' levels of compassion satisfaction and burnout, and 'low' levels of Secondary Traumatic Stress (STS). Compared to Site B, nurses at Site A had significantly higher compassion satisfaction (p=0.008) and lower STS scores (p=0.025), with site significantly predictive for compassion satisfaction (p<0.024) and STS (p<0.002). Nurses with postgraduate qualifications had significantly higher compassion satisfaction scores (p=0.027), and compassion satisfaction significantly increased with increasing duration of practice (p=0.042) as a nurse and in their current ICU (p=0.038). Burnout scores significantly reduced with increasing age, years of tenure and practice; burnout was predicted by lower years of tenure (p<0.016). These critical care nurses revealed profiles that, whilst not in crisis, fell short of the ideal high compassion satisfaction and moderate/low fatigue. More recent tenure flags those potentially at higher risk of compassion fatigue, whilst the better scores associated with postgraduate education and from one site need further exploration. Further research should develop understanding and interventions to enhance compassion satisfaction and support retention of this crucial nursing workforce.

Recent work has shown that solutions of the Boltzmann equation which use the so called {open_quotes}two-term{close_quotes} approximation provide an inadequate description of the transverse diffusion of electrons in argon gas at low values of E/N, contrary to earlier evidence. Previous determinations of the momentum transfer cross section for argon from the analysis of transport data have used two-term codes in good faith. Progress towards the determination of a new cross section in the energy range O - 4 eV, including an analysis of the energy dependence of the uncertainty in the derived cross section is reported.

Prevalence rates of Fear of Birth and postnatal depressive symptoms have not been explored in Chhattisgarh, India. To validate Hindi Wijma Delivery Experience Questionnaire and to study the prevalence of Fear of Birth and depressive symptoms among postnatal women. A cross-sectional survey at seventeen public health facilities in two districts of Chhattisgarh, India among postnatal women who gave birth vaginally or through C-section to a live neonate. Participants were recruited through consecutive sampling based on health facility records of daily births. Data were collected through one-to-one interviews using the Wijma Delivery Experience Questionnaire Version B and the Edinburgh Postnatal Depression Scale. Non-parametric associations and linear regression data analyses were performed. The Hindi Wijma Delivery Experience Questionnaire Version B had reliable psychometric properties. The prevalence of Fear of Birth and depressive symptoms among postnatal women were 13.1% and 17.1%, respectively, and their presence had a strong association (p<0.001). Regression analyses revealed that, among women having vaginal births: coming for institutional births due to health professionals' advice, giving birth in a district hospital and having postnatal depressive symptoms were associated with presence of FoB; while depressive symptoms were associated with having FoB, perineal suturing without pain relief, and giving birth to a low birth-weight neonate in a district hospital. The prevalence of Fear of Birth and depressive symptoms is influenced by pain management during childbirth and care processes between women and providers. These care practices should be improved for better mental health outcomes among postnatal women. Copyright © 2017 Australian College of Midwives. Published by Elsevier Ltd. All rights reserved.

Objectives. We examined associations between longitudinal neighborhood poverty trajectories and preterm birth (PTB). Methods. Using data from the Neighborhood Change Database (1970–2000) and the American Community Survey (2005–2009), we categorized longitudinal trajectories of poverty for California neighborhoods (i.e., census tracts). Birth data included 23 291 singleton California births from the Maternal and Infant Health Assessment (2003–2009). We estimated associations (adjusted for individual-level covariates) between PTB and longitudinal poverty trajectories and compared these to associations using traditional, cross-sectional measures of poverty. Results. Compared to neighborhoods with long-term low poverty, those with long-term high poverty and those that experienced increasing poverty early in the study period had 41% and 37% increased odds of PTB (95% confidence interval [CI] = 1.18, 1.69 and 1.09, 1.72, respectively). High (compared with low) cross-sectional neighborhood poverty was not associated with PTB (odds ratio = 1.08; 95% CI = 0.91, 1.28). Conclusions. Neighborhood poverty histories may contribute to an understanding of perinatal health and should be considered in future research. PMID:25880941

Despite the instruments on the right to adequate food adopted by the United Nations, there exists limited information on how this right is perceived. Following a major 2010 landslide disaster in the Bududa district of Eastern Uganda and the resettlement of some affected households into the Kiryandongo district in Western Uganda, we surveyed both districts to explore perceptions about the right to adequate food among households with different experiences; disaster-affected and controls. We deployed qualitative and quantitative techniques to a cross-sectional survey. The index respondent was the head of each randomly selected household from the landslide affected communities and controls from a bordering sub-county. Data was collected by interviews and focus group discussions (FGDs). Structured entries were tested statistically to report associations using Pearson's Chi-square at the 95% CI. Information from FGDs was transcribed, coded, sequenced and patterned. Findings from both techniques were triangulated to facilitate interpretations. Analysis included 1,078 interview entries and 12 FGDs. Significant differences between the affected and control households (P < 0.05) were observed with: age; education level; religious affiliation; existence of assets that complement food source; and having received relief food. Analysis between groups showed differences in responses on: whether everyone has a right to adequate food; who was supposed to supply relief food; whether relief food was adequate; and preferred choice on the means to ensure the right to adequate food. FGDs emphasized that access to land was the most important means to food and income. Affected households desired remedial interventions especially alternative land for livelihood. Despite the provision of adequate relief food being a state's obligation, there was no opportunity to exercise choice and preference. Comprehension and awareness of accountability and transparency issues was also low. Though a

Three meteorite specimens were used in a microwave scattering experiment to determine the scattering cross sections of stony meteorites and iron meteorites in the frequency range from 10 to 14 GHz. The results indicate that the stony meteorites have a microwave scattering cross section that is 30 to 50 percent of their projected optical cross section. Measurements of the iron meteorite scattering were inconclusive because of specimen surface irregularities.

Poster - 18: New features in EGSnrc for photon cross sections

Purpose: To implement two new features in the EGSnrc Monte Carlo system. The first is an option to account for photonuclear attenuation, which can contribute a few percent to the total cross section at the higher end of the energy range of interest to medical physics. The second is an option to use exact NIST XCOM photon cross sections. Methods: For the first feature, the photonuclear total cross sections are generated from the IAEA evaluated data. In the current, first-order implementation, after a photonuclear event, there is no energy deposition or secondary particle generation. The implementation is validated against deterministicmore » calculations and experimental measurements of transmission signals. For the second feature, before this work, if the user explicitly requested XCOM photon cross sections, EGSnrc still used its own internal incoherent scattering cross sections. These differ by up to 2% from XCOM data between 30 keV and 40 MeV. After this work, exact XCOM incoherent scattering cross sections are an available option. Minor interpolation artifacts in pair and triplet XCOM cross sections are also addressed. The default for photon cross section in EGSnrc is XCOM except for the new incoherent scattering cross sections, which have to be explicitly requested. The photonuclear, incoherent, pair and triplet data from this work are available for elements and compounds for photon energies from 1 keV to 100 GeV. Results: Both features are implemented and validated in EGSnrc.Conclusions: The two features are part of the standard EGSnrc distribution as of version 4.2.3.2.« less

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

To determine the association between exposure to disablism and the health and well-being of adults with intellectual disabilities. Cross-sectional survey. Secondary analysis of data extracted from the survey of Adults with Learning Difficulties in England 2003/4. Both self-reported exposure to bullying while at school and self-reported exposure to overt acts of disablism over the previous 12 months were associated with poorer self-reported health outcomes. In the vast majority of instances, these associations were stronger for people with lower levels of material or social resources. Exposure to overt acts of disablism may contribute to the health inequalities experienced by people with intellectual disabilities. Copyright © 2010 The Royal Society for Public Health.

2018-01-01

Positron-impact total scattering cross-sections for Li, Na, K, Rb, Cs and Fr atoms are calculated in the energy range from 5-5000 eV employing modified spherical complex optical potential formalism. The main aim of this work is to apply this formalism to the less studied positron-target collision systems. The results are compared with previous theoretical and experimental data, wherever available. In general, the present data show overall agreement and consistency with other results. Furthermore, we have done a comparative study of the results to investigate the effect of atomic size on the cross-sections as we descend through the group in the periodic table. We have also plotted a correlation graph of the present total cross-sections with polarizability and number of target electrons. The two correlation plots confirm the credibility and consistency of the present results. Besides, this is the first theoretical attempt to report positron-impact total cross-sections of alkali atoms over such a wide energy range.

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.

The Importance of the Maternal/Self-Role Satisfaction for Reducing Anxiety: A Cross-Sectional Survey of Japanese Mothers.

Iwasaki, Riho; Arimoto, Azusa; Naruse, Takashi; Nagata, Satoko; Murashima, Sachiyo

Women who rear children have two types of roles: the maternal role and the self-role. Previous studies have suggested that maternal role satisfaction is related to anxiety, but the importance of self-role satisfaction in promoting the health of mothers has received less attention. The changing roles of women in society, especially in urban areas, have altered mothers' views of child-rearing. Our primary focus was on the relationship between maternal/self-role satisfaction and anxiety in mothers. To examine this, we conducted a cross-sectional survey using self-administered questionnaires that were distributed in 2011 to 2,342 mothers attending the 18-month health checkup of their children, in 7 cities of the Tokyo metropolitan area. A total of 881 responded (effective response rate = 38.0%). Multiple regression analysis revealed that maternal role satisfaction and self-role satisfaction were both significantly and negatively associated with anxiety. Thus, self-role satisfaction should be considered alongside maternal role satisfaction in evaluating and reducing anxiety. Health care professionals in community settings should conduct comprehensive assessments of maternal role satisfaction and self-role satisfaction.

Community pharmacists are very accessible to most patients yet; they have been underutilized in the aspect of providing HIV care and services. The World Health Organisation recently recommended expanding community pharmacists' roles to address the increasing complexity of antiretroviral agents and co-infection drug regimen. This study therefore was designed to assess the readiness and willingness of community pharmacists in Nigeria to participate in the care of people living with HIV/AIDS and the possible inclusion of their pharmacy premises as sites for HIV care services. A descriptive cross sectional survey was carried out among 205 community pharmacists in south east, Nigeria between October, 2016 and February, 2017. Two hundred and five self-administered questionnaires were distributed to conveniently selected community pharmacists in the region. Data collected were analysed using SPSS version 23. Descriptive statistics was conducted for the demographics and percentage mean scores for each domain were computed. The variables in each domain were categorised into groups and simple percentages were used to show the percentage distribution of the variables. Cross tabulation was also carried out to show the relationship between the variables and groups' differences were explored using analysis of variance and P -values <0.05 were considered significant. All distributed questionnaires were filled and retrieved. The overall knowledge of HIV among the surveyed pharmacists was seen to be high (70.41%). Although the percentage attitude score of the respondents towards HIV care services was on the average (57%), they were highly willing and ready to use their premise to offer HIV services with a percentage mean readiness score of 87.32%. However, their perceived skills in carrying out these services were observed to be low. Community pharmacists in the south eastern part of Nigeria have high knowledge of HIV and a somewhat attitude towards HIV care services with high

Cross-Section Measurements in the Fast Neutron Energy Range

Generation IV focuses research for advanced nuclear reactors on six concepts. Three of these concepts, the lead, gas and sodium fast reactors (LFR, GFR and SFR) have fast neutron spectra, whereas a fourth, the super-critical water reactor (SCWR), can be configured to have a fast spectrum. Such fast neutron spectra are essential to meet the sustainability objective of GenIV. Nuclear data requirements for GenIV concepts will therefore emphasize the energy region from about 1 keV to 10 MeV. Here, the potential is illustrated of the GELINA neutron time-of-flight facility and the Van de Graaff laboratory at IRMM to measure the relevant nuclear data in this energy range: the total, capture, fission and inelastic-scattering cross sections. In particular, measurement results will be shown for lead and bismuth inelastic scattering for which the need was recently expressed in a quantitative way by Aliberti et al. for Accelerator Driven Systems. Even without completion of the quantitative assessment of the data needs for GenIV concepts at ANL it is clear that this particular effort is of relevance to LFR system studies.

Survival Mediated Heavy Element Capture Cross Sections

NASA Astrophysics Data System (ADS)

Loveland, Walter; Yao, Larry

2017-11-01

Formally, the cross section for producing a heavy evaporation residue, σEVR, in a fusion reaction can be written as where E is the center of mass energy, and T is the probability of the colliding nuclei to overcome the potential barrier in the entrance channel and reach the contact point. PCN is the probability that the projectile-target system will evolve from the contact point to the compound nucleus. Wsur is the probability that the compound nucleus will decay to produce an evaporation residue rather than fissioning. However, one must remember that the Wsur term effectively sets the allowed values of the spin, which in turn, restricts the values of the capture and fusion cross sections. We point out the implications of this fact for capture cross sections for heavy element formation reactions.

Precision (n,f) and (n, γ) cross sections are important for the network calculations of the radiochemical diagnostic chain for the U.S. DOE's Stockpile Stewardship Program. 242Pu(n, γ) cross section is relevant to the network calculations of Pu and Am. Additionally, new reactor concepts have catalyzed considerable interest in the measurement of improved cross sections for neutron-induced reactions on key actinides. To date, little or no experimental data has been reported on 242Pu(n, γ) for incident neutron energy below 50 keV. A new measurement of the 242Pu(n, γ) reaction was performed with the DANCE together with an improved PPAC for fission-fragment detection at LANSCE during FY14. The relative scale of the 242Pu(n, γ) cross section spans four orders of magnitude for incident neutron energies from thermal to ~ 30 keV. The absolute scale of the 242Pu(n, γ) cross section is set according to the measured 239Pu(n,f) resonance at 7.8 eV; the target was spiked with 239Pu for this measurement. The absolute 242Pu(n, γ) neutron capture cross section is ~ 30% higher than the cross section reported in ENDF for the 2.7 eV resonance. Latest results to be reported.

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

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.

To investigate the factors affecting the research productivity of young nursing faculty in Japan. An online survey targeting young nursing scholars (aged ≤ 39 years) who were members of the Japan Academy of Nursing Science was conducted from October to November 2012. Of 1634 potential respondents, 648 completed the survey (39.7%), and 400 full-time faculty of a baccalaureate degree program were selected for the analysis. The numbers of English-language and Japanese publications in the past 3 years were regressed onto personal characteristics, such as academic degree and type of university. The mean numbers of publications in English and Japanese in the past 3 years were 0.41 and 1.63, respectively. Holding a doctoral degree was significantly related to a higher number of publications in English and Japanese (e(β) = 5.78 and e(β) = 1.89, respectively). Working at a national university (e(β) = 2.15), having a research assistant (e(β) = 2.05), and the ability to read research articles in English (e(β) = 2.27) were significantly related to more English-language publications. Having the confidence to conduct quantitative research (e(β) = 1.67) was related to a larger number of Japanese publications. The lack of mentoring (e(β) = 0.97) and university workload (e(β) = 0.96) were associated with a lesser number of Japanese publications. The research productivity of young nursing faculty appeared to be quite low. Strategies to enhance research productivity in young nursing faculty, such as encouraging the achievement of a doctoral degree or enrichment of research resources, should be undertaken. © 2014 The Authors.

Shvelidze, T. D.; Malyuto, V. D.

Quantitative spectral classification of F, G and K stars with the 70-cm telescope of the Ambastumani Astrophysical Observatory in areas of the main meridional section of the Galaxy, and for which proper motion data are available, has been performed. Fundamental parameters have been obtained for 333 stars in four areas. Space densities of stars of different spectral types, the stellar luminosity function and the relationships between the kinematics and metallicity of stars have been studied. The results have confirmed and completed the conclusions made on the basis of some previous spectroscopic and photometric surveys. Many plates have been obtained for other important directions in the sky: the Kapteyn areas, the Galactic anticentre and the main meridional section of the Galaxy. The data can be treated with the same quantitative method applied here. This method may also be applied to other available and future spectroscopic data of similar resolution, notably that obtained with large format CCD detectors on Schmidt-type telescopes.

The data preprocessing in apparent resistivity pesudo-section construction of two-dimensional electrical resistivity tomography survey

NASA Astrophysics Data System (ADS)

Zhou, Q.

2015-12-01

Although three-dimensional (3-D) electrical resistivity tomography (ERT) survey has become a popular practice in the site characterization and process monitoring, the two-dimensional (2-D) ERT survey is still often used in the field. This is because that the 2-D ERT survey is relatively easy to do and the focus of site characterization is on the information of 2-D cross section, not necessarily of the 3-D subsurface structure. Examples of such practice include tunnel line and crossing fault survey. In these cases, depending on the property of surface soil to be surveyed, the 2-D ERT survey with pole-pole array may occasionally make us obtain quality good data, however it often gives us a suit of data set both with real and erroneous ones that incorporated the effects of electrode contact and not far enough far electrodes. Without preprocessing, the apparent resistivity pseudo-section constructed from this kind of data set may quite deviate from the real one and the information obtained from it may be misleading and even completely incorrect. In this study, we developed a method of far electrode dynamic correction that is appropriate for raw data preprocessing from 2-D pole-pole array ERT survey. Based on this method, we not only can find and delete the abnormal data points easily, but also can position the coordinates of far electrodes actually working in the field, thus delete the far electrode effects and make best use of the looked strange data points. The method also makes us to be able to judge the effects of electrode contact and avoid using such data points in the following apparent resistivity pseudo-section construction. With this preprocessing to the data set, the constructed apparent resistivity pseudo-section is demonstrated to be more approximate to the real one. This makes the following reversion calculation more robust. We'll introduce this far electrode dynamic correction method and show application examples in the meeting.

The purpose of this cross-sectional survey was to evaluate attitudes and opinions of doctors of chiropractic (DCs) specializing in pediatric care toward patient safety. The Medical Office Survey on Patient Safety Culture of the Agency for Healthcare Research and Quality was adapted for providers who use spinal manipulation therapy and sent out to 2 US chiropractic organizations' pediatric council members (n = 400) between February and April 2014. The survey measured 12 patient safety dimensions and included questions on patient safety items and quality issues, information exchange, and overall clinic ratings. Data analyses included a percent composite average and a nonrespondent analysis. The response rate was 29.5% (n = 118). Almost one- third of respondents' patients were pediatric (≤17 years of age). DCs with a pediatric certification were 3 times more likely to respond (P < .001), but little qualitative differences were found in responses. The patient safety dimensions with the highest positive composite percentages were Organizational Learning (both administration and clinical) and Teamwork (>90%). Patient Care Tracking/Follow-up and Work Pressure and Pace were patient safety dimensions that had the lowest positive composite scores (<85%). The responses also indicated that there was concern regarding information exchange with insurance/third-party payors. Two quality issues identified for improvement were (1) updating a patient's medication list and (2) following up on critically abnormal results from a laboratory or imaging test within 1 day. The average overall patient safety rating score indicated that 83% of respondents rated themselves as "very good" or "excellent." Compared with 2014 Agency for Healthcare Research and Quality physician referent data from medical offices, pediatric DCs appear to have more positive patient safety attitudes and opinions. Future patient safety studies need to prospectively evaluate safety performance with direct feedback

This analysis seeks to identify strengths and gaps in the existing facility capacity for intrapartum and immediate postpartum fetal and neonatal care, using data collected as a part of Malawi’s Helping Babies Breath program evaluation. From August to September 2012, the Maternal and Child Health Integrated Program (MCHIP) conducted a cross-sectional survey in 84 Malawian health facilities to capture current health facility service availability and readiness and health worker capacity and practice pertaining to labor, delivery, and immediate postpartum care. The survey collected data on availability of equipment, supplies, and medications, and health worker knowledge and performance scores on intrapartum care simulation and actual management of real clients at a subset of facilities. We ran linear regression models to identify predictors of high simulation performance of routine delivery care and management of asphyxiated newborns across all facilities surveyed. Key supplies for infection prevention and thermal care of the newborn were found to be missing in many of the surveyed facilities. At the health center level, 75% had no clinician trained in basic emergency obstetric care or newborn care and 39% had no midwife trained in the same. We observed that there were no proportional increases in available transport and staff at a facility as catchment population increased. In simulations of management of newborns with breathing problems, health workers were able to complete a median of 10 out of 16 tasks for a full-term birth case scenario and 20 out of 30 tasks for a preterm birth case scenario. Health workers who had more years of experience appeared to perform worse. Our study provides a benchmark and highlights gaps for future evaluations and studies as Malawi continues to make strides in improving facility-based care. Further progress in reducing the burden of neonatal and fetal death in Malawi will be partly predicated on guaranteeing properly equipped and

Background Identifying essential competencies in end-of-life care, as well as general practitioners’ (GPs) confidence in these competencies, is essential to guide training and quality improvement efforts in this domain. Aim To determine which competencies in end-of-life care are considered important by GPs, to assess GPs’ confidence in these competencies in a European context and their reasons to refer terminally ill patients to a specialist. Design and Setting Cross-sectional postal survey involving a stratified random sample of 2000 GPs in Switzerland in 2014. Method Survey development was informed by a previous qualitative exploration of relevant end-of-life GP competencies. Main outcome measures were GPs’ assessment of the importance of and confidence in 18 attributes of end-of-life care competencies, and reasons for transferring care of terminally-ill patients to a specialist. GP characteristics associated with main outcome measures were tested using multivariate regression models. Results The response rate was 31%. Ninety-nine percent of GPs considered the recognition and treatment of pain as important, 86% felt confident about it. Few GPs felt confident in cultural (16%), spiritual (38%) and legal end-of-life competencies such as responding to patients seeking assisted suicide (35%) although more than half of the respondents regarded these competencies as important. Most frequent reasons to refer terminally ill patients to a specialist were lack of time (30%), better training of specialists (23%) and end-of-life care being incompatible with other duties (19%). In multiple regression analyses, confidence in end-of-life care was positively associated with GPs’ age, practice size, home visits and palliative training. Conclusions GPs considered non-somatic competencies (such as spiritual, cultural, ethical and legal aspects) nearly as important as pain and symptom control. Yet, few GPs felt confident in these non-somatic competencies. These findings

This study aimed to explore determinants of second pregnancy and underlying reasons among pregnant Chinese women. The study was a population-based cross-sectional survey. 16 hospitals in 5 provinces of Mainland China were included. A total of 2345 pregnant women aged 18 years or above were surveyed face to face by investigators between June and August 2015. The pregnancy statuses (first or second pregnancy) and reasons for entering second pregnancy. A total of 1755 (74.8%) and 590 (25.2%) women in their respective first and second pregnancies were enrolled in this study. The most common self-reported reasons for entering second pregnancy among participants included the benefits to the first child (26.1%), love of children (25.8%), adoption of the 2-child policy (11.5%), concerns about losing the first child (7.5%) and suggestions from parents (7.5%). Pregnant women with low (prevalence ratio (PR) 1.96; 95% CI 1.62 to 2.36) and moderate education level (PR 1.97; 95% CI 1.65 to 2.36) were more likely to have a second pregnancy than their higher educated counterparts. Income was inversely associated with second pregnancy. However, unemployed participants (PR 0.79; 95% CI 0.66 to 0.95) were less likely to enter a second pregnancy than those employed. Women with moderate education were 3 times more likely to have a second child following the '2-child policy' than the low education level subgroup. 1 in every 4 pregnant women is undergoing a second pregnancy. The benefits of the firstborn or the love of children were the key drivers of a second pregnancy. Low socioeconomic status was positively associated with a second pregnancy as well. The new 2-child policy will have an influence on China's demographics. Published by the BMJ Publishing Group Limited.

In The Netherlands, approximately 45% of patients' requests for euthanasia are granted by a physician. After a rejected request, some patients approach non-physicians and ask them for assistance in suicide. Recently, a non-physician who assisted his mother's suicide was declared guilty without punishment. The aim of the current study was to investigate the opinion of the Dutch general public on non-physician-assisted suicide. A cross-sectional survey among the Dutch general public was performed. A total of 1113 respondents were included (response rate 80%). The survey covered two case descriptions in which a patient asks a non-physician for assisted suicide after a non-granted request for physician-assisted dying. In both cases, a son, friend or professional facilitates the suicide by either the provision of information or the purchase of lethal medication. Respondents were invited to give their opinion on these cases and in addition on 10 propositions on non-physician-assisted suicide. When a son provides information on how to acquire lethal medication in case of a patient with a terminal illness, this involvement is accepted by 62% of the respondents. The actual purchase of lethal medication receives less support (38%). If the patient suffers without a serious disease, both forms of assistance are less accepted (46% and 24%, respectively). In addition, only 21% support the legalisation of non-physician-assisted suicide. The Dutch public prefer involvement of a physician in assisted suicide (69%). The Dutch general public consider non-physician-assisted suicide in some specific cases a tolerable alternative for patients with a rejected request for physician-assisted dying if the assistance is limited to the provision of information. However, the majority do not support the legalisation of non-physician-assisted suicide. Published by the BMJ Publishing Group Limited.

Interest in nephrology careers among internal medicine residents in the United States is declining. Our objective was to assess the impact of the presence of a nephrology fellowship training program on perceptions and career interest in nephrology among internal medicine residents. A secondary objective was to identify commonly endorsed negative perceptions of nephrology among internal medicine residents. This was a repeated cross-sectional survey of internal medicine residents before (Group 1) and 3 years after (Group 2) the establishment of nephrology fellowship programs at two institutions. The primary outcome was the percentage of residents indicating nephrology as a career interest in Group 1 vs. Group 2. Secondary outcomes included the frequency that residents agreed with negative statements about nephrology. 131 (80.9%) of 162 residents completed the survey. 19 (14.8%) residents indicated interest in a nephrology career, with 8 (6.3%) indicating nephrology as their first choice. There was no difference in career interest in nephrology between residents who were exposed to nephrology fellows during residency training (Group 2) and residents who were not (Group 1). The most commonly endorsed negative perceptions of nephrology were: nephrology fellows have long hours/burdensome call (36 [28.1%] of residents agreed or strongly agreed), practicing nephrologists must take frequent/difficult call (35 [27.6%] agreed or strongly agreed), and nephrology has few opportunities for procedures (35 [27.3%] agreed or strongly agreed). More residents in Group 2 agreed that nephrology is poorly paid (8.9% in Group 1 vs. 20.8% in Group 2, P = 0.04), whereas more residents in Group 1 agreed that nephrologists must take frequent/difficult call (40.0% in Group 1 vs. 18.1% in Group 2, P = 0.02).

Phys. 106), 9602 (1997), and references therein. that combines the Mott cross section at low incident energies T and the Bethe cross section at high T was applied to fluorine compounds of interest to plasma processing of semiconductors (CF_4, CHF_3, C_2F_6, C_4F_8, etc.). The theory provides total ioniztion cross sections in an analytic form from the threshold to a few keV in T, making it convenient to use the theory for modeling. The theory is particularly effective for closed-shell molecules. The theoretical cross sections are compared to available experimental data.

The cross section for 236U fission in the neutron-energy range E n = 0.001 20 keV was measured by using the INR RAS (Institute of Nuclear Research, Russian Academy of Sciences, Moscow) LSDS-100 neutron spectrometer of the lead slowing-down spectrometer type. The resonance fission areas of the resonances at 5.45 eV and 1.28 keV were found, and the fission widths of these resonances were evaluated. The cross section for the 238U( n, f) fission process was measured, and the threshold sensitivity of the LSDS-100 to small values of fission cross sections was estimated. The well-known intermediate structure in the cross section for the neutron-induced subbarrier fission of 236U was confirmed.

A new automated method for the determination of cross-section limits in ephemeral gullies

Castillo, Carlos; Ángel Campo-Bescós, Miguel; Casalí, Javier; Giménez, Rafael

2017-04-01

The assessment of gully erosion relies on the estimation of the soil volume enclosed by cross sections limits. Both 3D and 2D methods require the application of a methodology for the determination of the cross-section limits what has been traditionally carried out in two ways: a) by visual inspection of the cross-section by a certain expert operator; b) by the automated identification of thresholds for different geometrical variables such as elevation, slope or plan curvature obtained from the cross-section profile. However, for these last methods, typically, the thresholds are not of general application because they depend on absolute values valid only for the local gully conditions where they were derived. In this communication we evaluate an automated method for cross-section delimitation of ephemeral gullies and compare its performance with the visual assessment provided by five scientists experienced in gully erosion assessment, defining gully width, depth and area for a total of 60 ephemeral gullies cross-sections obtained from field surveys conducted on agricultural plots in Navarra (Spain). The automated method only depends on the calculation of a simple geometrical measurement, which is the bank trapezoid area for every point of each gully bank. This rectangle trapezoid (right-angled trapezoid) is defined by the elevation of a given point, the minimum elevation and the extremes of the cross-section. The gully limit for each bank is determined by the point in the bank with the maximum trapezoid area. The comparison of the estimates among the different expert operators showed large variation coefficients (up to 70%) in a number of cross-sections, larger for cross sections width and area and smaller for cross sections depth. The automated method produced comparable results to those obtained by the experts and was the procedure with the highest average correlation with the rest of the methods for the three dimensional parameters. The errors of the automated
