    Background Considerable research has documented that exposure to traumatic events has negative effects on physical and mental health. Much less research has examined the predictors of traumatic event exposure. Increased understanding of risk factors for exposure to traumatic events could be of considerable value in targeting preventive interventions and anticipating service needs. Method General population surveys in 24 countries with a combined sample of 68 894 adult respondents across six continents assessed exposure to 29 traumatic event types. Differences in prevalence were examined with cross-tabulations. Exploratory factor analysis was conducted to determine whether traumatic event types clustered into interpretable factors. Survival analysis was carried out to examine associations of sociodemographic characteristics and prior traumatic events with subsequent exposure. Results Over 70% of respondents reported a traumatic event; 30.5% were exposed to four or more. Five types – witnessing death or serious injury, the unexpected death of a loved one, being mugged, being in a life-threatening automobile accident, and experiencing a life-threatening illness or injury – accounted for over half of all exposures. Exposure varied by country, sociodemographics and history of prior traumatic events. Being married was the most consistent protective factor. Exposure to interpersonal violence had the strongest associations with subsequent traumatic events. Conclusions Given the near ubiquity of exposure, limited resources may best be dedicated to those that are more likely to be further exposed such as victims of interpersonal violence. Identifying mechanisms that account for the associations of prior interpersonal violence with subsequent trauma is critical to develop interventions to prevent revictimization. PMID:26511595

    The purpose of this study was to assess the current status of patient radiation exposure tracking internationally, gauge interest and develop recommendations for implementation. A survey questionnaire was distributed to representatives of countries to obtain information, including the existence of a patient exposure tracking program currently available in the country, plans for future programs, perceived needs and goals of future programs, which examinations will be tracked, whether procedure tracking alone or dose tracking is planned, and which dose quantities will be tracked. Responses from 76 countries, including all of the six most populous countries and 16 of the 20 most populous, showed that although no country has yet implemented a patient exposure tracking program at a national level, there is increased interest in this issue. Eight countries (11%) indicated that such a program is actively being planned and 3 (4%) stated that they have a program for tracking procedures only, but not for dose. Twenty-two (29%) feel that such a program will be “extremely useful”, 46 (60%) “very useful” and 8 (11%) “moderately useful”, with no respondents stating “Mildly useful” or “Not useful”. Ninety-nine percent of countries indicated an interest in developing and promoting such a program. In a first global survey covering 76 countries, it is clear that no country has yet achieved exposure tracking at a national level, although there are successful examples at sub-national level. Almost all have indicated interest and some have plans to achieve dose tracking in the near future. PMID:22840382

    Full Text Available Recreational sun exposure accounts for a large number of acute and chronic dermatological diseases, including skin cancer. This study aimed at estimating the one-year prevalence of sun exposure and skin health-associated knowledge and attitudes among Austrian citizens. The population-based UVSkinRisk survey investigated a representative sample of Austrian adults using a structured questionnaire. In total, 1500 study subjects (median age 33.0 years, 50.5% females participated in this questionnaire survey. Among study participants, prevalence of sun exposure was 47%, with slightly higher rates in males (48% compared to females (46%. Younger age, lower professional category, darker skin type, motives to tan, sunbed use, sunburn, and outdoor sport activity increased the odds for prevalent sun exposure. This is the first population-based study evaluating the prevailing sun exposure and recreational habits influencing skin health among Austrian citizens. Despite public media campaigns educating on the harmful effects of sunlight exposure, we found a high prevalence of self-reported sunlight exposure. The results suggest that multifaceted socio-cultural characteristics stimulate recreational sun exposure and tanning habits. Communicating individualized Public (Skin Health messages might be the key to prevent photo-induced skin health hazards in light-skinned populations. The practical and theoretical implications of these findings are discussed.

    This study examined the prevalence of traumatic events and the conditional probability of posttraumatic stress disorder (PTSD) associated with both specific and broad classes of events in a nationally representative sample from France. The sample (N = 1,436) was a part of the European Study of the Epidemiology of Mental Disorders Survey (ESEMeD), under the WHO World Mental Health Surveys-2000 initiative. Overall, exposure to any traumatic event was 72.7%, which appeared to be lower than what has been reported in Sweden (80.8%), similar to data from the Netherlands (71.1%), and higher than what has been reported in Spain (54.0%), Italy (56.1%), Northern Ireland (60.6%) or the U.S (55.9%). Lifetime prevalence of PTSD was 3.9%, lower than in the United States (7.8%), Sweden (5.6%), or Northern Ireland (8.8%), but higher than in Spain (2.2%) or Italy (2.4%). Being beaten up by a romantic partner (25.0%), having a child with serious illness (23.5%), and rape (21.5%) were associated with the highest risk of PTSD. The average duration of PTSD was 5.3 years (0.2-28.1). The burden of PTSD in France appeared to come from the consequences of violence and social network events suggesting that prevention efforts might focus on limiting the occurrence of exposure to avoidable events such as violence as well as provide support for persons exposed to social network events.

    The results of a cross-sectional clinical field survey of 90 telephone cable splicers are presented. Despite the rare occurrence of clinically overt lead poisoning among cable splicers, the observed prevalence of symptoms was 29% for lead-associated central nervous system symptoms and 21% for gastrointestinal symptoms. These two groups of symptoms were directly related to zinc protoporphyrin (ZPP) levels but no relationship was found between them and blood lead concentrations. Only 5% of the workers had significantly elevated blood lead levels (> 40 ..mu..g/100 ml). Because of the intermittent lead exposure encountered in this trade, individuals were identified with normal blood lead levels associated with elevated zinc protoporphyrin concentrations, indicating the difference in biological significance between exposure-(blood lead) and biological-response tests (ZPP). Suggestion is made that both types of diagnostic tests be utilized in the medical surveillance of lead-exposed workers.

    Dental healthcare workers (DHWs) are at risk for occupational exposure to bloodborne pathogens (BBPs). The Occupational Safety and Health Administration Bloodborne Pathogens Standard requires employers to have a written exposure control plan (ECP) detailing methods and means to reduce and manage occupational BBP exposures. Because little information is available on whether ECPs are created and used, the National Institute for Occupational Safety and Health and the Organization for Safety, Asepsis and Prevention conducted an online survey to determine if dental practices had an ECP, whether present ECPs had the necessary components, and if impediments existed to prevent having an ECP in place. Respondents were primarily from nonfranchised practices (69%) and dentists who owned the practice (63%). Seventy-two percent of survey participants had an ECP, and 20% were unaware of any federal requirements for an ECP prior to the survey. Engineering controls were used by many practices, although the type varied. Fifteen percent of practices did not offer the hepatitis B vaccine for employees. The survey revealed many dental practices were unaware of or were lacking required elements of the ECP. Findings from this survey indicate DHWs would benefit from increased education regarding methods to prevent occupational exposures to BBPs.

    Since legislation prohibiting tobacco advertising in traditional media, online communication platforms and social media have become one of the few avenues for the tobacco industry to promote its products to Australians. Little is currently known about the exposure of young people to these new media promotions. To measure exposure to Internet-based tobacco advertising and branding among Australian youth, identify common formats of branding encountered, and examine the association between exposure and smoking susceptibility. The Tobacco Promotion Impact Study is a repeat cross-sectional telephone survey of young people (12-24 years) in 2 Australian states, conducted yearly from 2010 to 2013 (total n=8820). The survey included questions about past-month exposure to Internet-based tobacco advertising and tobacco company branding. Changes in levels of exposure, characteristics of exposed youth, and the association between exposure and smoking susceptibility were explored. Past-month exposure to Internet-based tobacco advertising and branding among young people increased over the years of the survey (advertising: 21% in 2010 to 29% in 2013; branding: 20% in 2010 to 26% in 2013). The participants who were younger, female, from lower socioeconomic status, and never-smokers were more likely to report exposure. Facebook was the most commonly cited platform for encountering tobacco branding in 2013 (22% of all branding). Compared with young people interviewed in 2013, participants in 2010 were significantly less likely to report exposure to tobacco branding on social media (odds ratio [OR] 0.26, 95% CI 0.20-0.33, Pbranding (OR 1.32, 95% CI 1.11-1.57, P=.002) or branding alone (OR 1.39, 95% CI 1.10-1.77, P=.007) were significant predictors of smoking susceptibility. Ensuring tobacco advertising bans are inclusive of Internet-based media is essential. Given the global nature of Internet-based content, cooperation among signatory nations to the World Health Organization

    The World Health Organization has declared that violence is a global public health problem. The prevalence of violence exposure among adults with intellectual and unspecific disabilities has been demonstrated in several studies, whereas only a few articles on people with sensory disabilities have been published. The aim of this study was to investigate the prevalence and risk for exposure to physical violence, psychological offence, or threats of violence in people with physical and/or sensory disabilities, compared with people with no such disabilities, controlling for socioeconomic data. Data from a public health survey were analyzed. A nationally representative sample of women and men aged 16 to 84 years had answered a questionnaire. In the present study, the whole sample, comprised of 25,461 women and 21,545 men, was used. Women with auditory disabilities were generally more often violence exposed than non-disabled women, whereas men with physical disabilities were more often violence exposed than non-impaired men. Some age groups among both women and men with visual disabilities had higher prevalence rates than women and men without disabilities. The adjusted odds ratios (ORs) were significantly higher among the auditory impairment group for exposure to physical (OR = 1.4, confidence interval [CI] = [1.1, 1.9]) and psychological (OR = 1.4, CI = [1.1, 1.8]) violence among women. Men with physical disabilities had raised odds ratios for physical violence (OR = 1.7, CI = [1.2, 2.4]) and psychological violence (OR = 1.4, CI = [1.0, 2.0]) compared with the non-disabled group. Both men and women with a physical or sensory disability showed higher odds of being exposed to violence than men and women without a disability. The results indicated that socioeconomic situation, smoking, and hazardous drinking strengthened the association between impairment and violence.

    A survey of time-weighted average (TWA) personal inhalable dust exposures for woodworkers in 15 Australian furniture factories was undertaken. There was significant variation in the individual dust measurements with mean exposures of 3.2, 5.2, and 3.5 mg/m3 for wood machinists, cabinetmakers, and chair framemakers, respectively. Hardwoods, softwoods, and reconstituted woods are used in the industry, but only minor differences in mean exposures or particle size distributions were found for the broad categories. In addition, a modified British Medical Research Council respiratory questionnaire was used to obtain information about work-related symptoms and job activities. Compared with a control group, the woodworkers reported more eye, ear, and nasal problems, with the differences being statistically significant. However, among the woodworkers themselves, with the exception of several nasal symptoms, the prevalences of reported symptoms were poorly correlated with gravimetric measurements of personal dust exposure. The problem of selection bias in cross-sectional studies is discussed. For a mean TWA personal exposure of about 3 mg/m3, hardwood users were more likely to report nasal symptoms than users of reconstituted wood. The question of appropriate exposure standards for woods in general is addressed by reference to those important health effects, besides sino-nasal cancer, that have been investigated. Further exposure guidelines should be formulated for groups of woods that are known to cause a common health effect, such as nasal/respiratory sensitization.

    Alcohol marketing is known to be a significant risk factor for underage drinking. However, little is known about youth and adult exposure to alcohol advertising in digital and social media. This study piloted a comparative assessment of youth and adult recall of exposure to online marketing of alcohol. From September to October 2013, a pilot survey of past 30-day exposure to alcohol advertising and promotional content in traditional and digital media was administered to a national sample of 1,192 youth (ages 13 to 20) and 1,124 adults (ages ≥21) using a prerecruited Internet panel maintained by GfK Custom Research. The weighted proportions of youth and adults who reported this exposure were compared by media type and by advertising and promotional content. Youth were more likely than adults to recall exposure to alcohol advertising on television (69.2% vs. 61.9%), radio (24.8% vs. 16.7%), billboards (54.8% vs. 35.4%), and the Internet (29.7% vs. 16.8%), but less likely to recall seeing advertising in magazines (35.7% vs. 36.4%). Youth were also more likely to recall seeing advertisements and pictures on the Internet of celebrities using alcohol (36.1% vs. 20.8%) or wearing clothing promoting alcohol (27.7% vs. 15.9%), and actively respond (i.e., like, share, or post) to alcohol-related content online. Youth report greater exposure to alcohol advertising and promotional content than adults in most media, including on the Internet. These findings emphasize the need to assure compliance with voluntary industry standards on the placement of alcohol advertising and the importance of developing better tools for monitoring youth exposure to alcohol marketing, particularly on the Internet.

    Latin American countries (Argentina, Brazil, Chile, Costa Rica, Cuba, Ecuador, El Salvador, Guatemala, Mexico, Nicaragua, Paraguay, Uruguay and Venezuela) working under the International Atomic Energy Agency (IAEA) Technical Cooperation Programme: TSA3 Radiological Protection of Patients in Medical Exposures have joined efforts in the optimisation of radiation protection in mammography practice. Through surveys of patient doses, the region has a unique database of diagnostic reference levels for analogue and digital equipment that will direct future optimisation activities towards the early detection of breast cancer among asymptomatic women. During RLA9/057 (2007-09) 24 institutions participated with analogue equipment in a dose survey. Regional training on methodology and measurement equipment was addressed in May 2007. The mean glandular dose (DG) was estimated using the incident kerma in air and relevant conversion coefficients for both projections craneo caudal and mediolateral oblique (CC and MLO). For Phase 2, RLA9/067 (2010-11), it was decided to include also digital systems in order to see their impact in future dose optimisation activities. Any new country that joined the project received training in the activities through IAEA expert missions. Twenty-nine new institutions participated (9 analogue and 20 digital equipment). A total of 2262 patient doses were collected during this study and from them D(G) (mGy) for both projections were estimated for each institution and country. Regional results (75 percentile in mGy) show for CC and MLO views, respectively: RLA9/057 (analogue) 2.63 and 3.17; RLA/067: 2.57 and 3.15 (analogue) and 2.69 and 2.90 (digital). Regarding only digital equipment for CC and MLO, respectively, computed radiography systems showed 2.59 and 2.78 and direct digital radiography (DDR) systems 2.78 and 3.04. Based on the IAEA Basic Safety Standard (BSS) reference dose (3 mGy), it can be observed that there is enough room to start

    Much of what is known about child abuse in Canada has come from reported cases of child abuse and at-risk samples, which likely represent the most severe cases of child abuse in the country. The objective of the current study is to examine the prevalence of a broad range of child abuse experiences (physical abuse, sexual abuse, and exposure to IPV) and investigate how such experiences and sociodemographic variables are related to contact with child protection organizations in Canada using a representative general population sample. Data were drawn from the 2012 Canadian Community Health Survey: Mental Health collected from the 10 provinces using a multistage stratified cluster design (n=23,395; household response rate=79.8%; aged 18 years and older). Physical abuse only (16.8%) was the most prevalent child abuse experience reported with the exposure to specific combinations of two or more types of child abuse ranging from 0.4% to 3.7%. Only 7.6% of the adult population with a history of child abuse reported having had contact with child protection organizations. Experiencing all three types of child abuse was associated with the greatest odds of contact with child protection organizations (AOR=15.8; 95% CI=10.1 to 24.6). Physical abuse only was associated with one of the lowest odds of contact with child protection organizations. Preventing child abuse is widely acknowledged as an important, but challenging public health goal. Strategies to increase reporting of child abuse may help to protect children and to connect families with necessary services. One obvious priority would be physical abuse.

  2. Bulletin Survey - Early Results

    CERN Multimedia

    2002-01-01

    There was a good response to our questionnaire on the Bulletin (around 450 so far). Many thanks to all of you - your views are invaluable to us. Pending publication of the full figures, which will give latecomers time to take part in the survey, here we give here answers some of your most frequent comments. Thank you for the many warm tributes and messages of encouragement we received. We also received criticisms about the way information is handled in the Bulletin and on its circulation. In today's issue we reply to these two points. Why is the Bulletin politically correct ? Many respondents reproach the Bulletin for a lack of objectivity and for being too politically correct to the point of being a propaganda organ. It is true that the Bulletin is not a newspaper, but rather a bulletin of communication (like SLAC's Beam Line). What is the difference ? A newspaper is objectively independent of the subjects it reports on, and when its reporters write stories they dig around for information from all parties...

  3. Validity of a Job-Exposure Matrix for Psychosocial Job Stressors: Results from the Household Income and Labour Dynamics in Australia Survey.

    Directory of Open Access Journals (Sweden)

    A Milner

    Full Text Available A Job Exposure Matrix (JEM for psychosocial job stressors allows assessment of these exposures at a population level. JEMs are particularly useful in situations when information on psychosocial job stressors were not collected individually and can help eliminate the biases that may be present in individual self-report accounts. This research paper describes the development of a JEM in the Australian context.The Household Income Labour Dynamics in Australia (HILDA survey was used to construct a JEM for job control, job demands and complexity, job insecurity, and fairness of pay. Population median values of these variables for all employed people (n = 20,428 were used to define individual exposures across the period 2001 to 2012. The JEM was calculated for the Australian and New Zealand Standard Classification of Occupations (ANZSCO at the four-digit level, which represents 358 occupations. Both continuous and binary exposures to job stressors were calculated at the 4-digit level. We assessed concordance between the JEM-assigned and individually-reported exposures using the Kappa statistic, sensitivity and specificity assessments. We conducted regression analysis using mental health as an outcome measure.Kappa statistics indicate good agreement between individually-reported and JEM-assigned dichotomous measures for job demands and control, and moderate agreement for job insecurity and fairness of pay. Job control, job demands and security had the highest sensitivity, while specificity was relatively high for the four exposures. Regression analysis shows that most individually reported and JEM measures were significantly associated with mental health, and individually-reported exposures produced much stronger effects on mental health than the JEM-assigned exposures.These JEM-based estimates of stressors exposure provide a conservative proxy for individual-level data, and can be applied to a range of health and organisational outcomes.

    Although fetal development is known to be sensitive to environmental agents, relatively little epidemiologic research has addressed this concern. Effects on pregnancy outcome of self-reported parental exposure to pesticides and to radiation were examined using data from the National Natality and Fetal Mortality Surveys, large national probability samples of live births and stillbirths occurring in 1980. In case-control analyses, maternal exposure to pesticides at home or work was associated with increased risk of stillbirth (odds ratios (ORs) = 1.5-1.6). Paternal pesticide exposure was associated with stillbirth (ORs = 1.2-1.4) and delivery of small-for-gestational-age infants (ORs = 1.4-2.0). A small increased risk of stillbirth (OR = 1.3) was found in relation to either parent's reported exposure to radiation. In spite of limitations in the quality of exposure data and the possibility of biased recall related to pregnancy outcome, associations of reported pesticide exposure to either parent with risk of stillbirth and small-for-gestational-age infants warrant further evaluation.

We examine the prevalence of psychiatric disorders and frequency of trauma exposures by position on the rural-urban continuum.The National Comorbidity Survey Replication (NCS-R was used to evaluate psychiatric disorders among a nationally-representative sample of the U.S. population. Rurality was designated using the Department of Agriculture's 2003 rural-urban continuum codes (RUCC, which differentiate counties into levels of rurality by population density and adjacency to metropolitan areas. Lifetime psychiatric disorders included post-traumatic stress disorder (PTSD, anxiety disorders, major depressive disorder, mood disorders, impulse-control disorders, and substance abuse. Trauma exposures were classified as war-related, accident-related, disaster-related, interpersonal or other. Weighted logistic regression models examined the odds of psychiatric disorders and trauma exposures by position on the rural-urban continuum, adjusted for relevant covariates.75% of participants were metropolitan, 12.2% were suburban, and 12.8% were from rural counties. The most common disorder reported was any anxiety disorder (38.5%. Drug abuse was more common among metropolitan (8.7%, p = 0.018, compared to nonmetropolitan (5.1% suburban, 6.1% rural participants. A one-category increase in rurality was associated with decreased odds for war-related trauma (aOR = 0.86, 95%CI 0.78-0.95. Rurality was not associated with risk for any other lifetime psychiatric disorders or trauma exposure.Contrary to the expectation of some rural primary care providers, the frequencies of most psychiatric disorders and trauma exposures are similar across the rural-urban continuum, reinforcing calls to improve mental healthcare access in resource-poor rural communities.

    E-cigarettes are frequently advertised and portrayed in the media as less harmful compared with regular cigarettes. Earlier surveys reported public perceptions of harms to people using e-cigarettes; however, public perceptions of harms from exposure to secondhand vapour (SHV) have not been studied. We examined associations between self-reported exposure to e-cigarette advertising, media coverage, and interpersonal discussion and perceived harms of SHV. Observational study. National online sample of US adults aged ≥18 years. 1449 US adults (mean age 49.5 years), 51.3% female, 76.6% non-Hispanic Caucasian, 7.5% African-American, 10.0% Hispanic and 5.9% other races. Perceived harm measures included (1) harmfulness of SHV to one's health, (2) concern about health impact of breathing SHV and (3) comparative harm of SHV versus secondhand smoke (SHS). Predictors were (1) self-reported frequency of exposure to e-cigarette advertising, media coverage and interpersonal discussion (close friends or family) and (2) perceived valence of exposure from each source. Covariates were demographic characteristics, cigarette smoking status and e-cigarette use, and were weighted to the general US adult population. More frequent interpersonal discussion was associated with lower perceived harmfulness of SHV to one's health and lower perceived comparative harm of SHV versus SHS. Frequency of e-cigarette ad and other media exposure were not significant predictors. Perceived negative valence of ad exposure and interpersonal discussion (vs no exposure) was associated with higher perceived harm across all three outcomes, while negative valence of media coverage was associated with higher concern about health impact of breathing SHV. Perceived positive valence (vs no exposure) of interpersonal discussion was associated with lower perceived harm across all three outcomes about health impact of breathing SHV.

    We aimed to evaluate the association of exposure to lead with glycated hemoglobin (HbA1c), fasting glucose levels (FGLs), and the likelihood for dysglycemia. We accessed data from Canada Health and Measures Survey. General linear models were used to estimate the association between blood lead concentrations (BPb) and both HbA1c and FGLs, while controlling for confounders. Multivariate logistic regression was used for assessing the relation between BPb and the likelihood for dysglycemia. FGLs in participants with moderate BPb (2.5-5.0 μg/dL) were 1.03 (95 % CI 1.00-1.06) times higher compared with participants with BPb Lead exposure was associated with the likelihood for neither FGLs ≥ 1.10 g/L nor HbA1c ≥ 5.7 %. The association between lead exposure and dysglycemia, if any, is likely to be very modest, at least at the population level.

    Waterpipe tobacco smoking (WTS) is a growing public health concern worldwide yet little is known about the epidemiology of use among young people. The objectives of this study were to examine the prevalence, patterns and correlates of WTS among students across Lebanon. The study design was a cross sectional survey. 126-item tobacco questionnaire was conducted among 1128 sixth and seventh grade students across Lebanon. Current patterns of use were descriptively analysed, and logistic regression models examined correlates of WTS. Ever WTS prevalence was 44.3%, current WTS prevalence was triple that of cigarettes (22.1% vs 7.4%), and 40.0% of current users were at least weekly or daily smokers. Initiation and patterns of use, as well as addiction and cessation attitudes have been reported. Significant correlates of current WTS included older age, reduced religiosity, peer and parent tobacco use, recent waterpipe advertisement exposure, increased pluralistic ignorance and current cigarette use. Significant correlates of ever WTS were similar to current WTS, but included second hand waterpipe tobacco smoke exposure at home and did not include recent waterpipe advertisement exposure. Neither gender nor socio-economic status were significant correlates of current or ever WTS. Waterpipe is the most common form of tobacco smoking, and is used regularly, among sixth and seventh grade Lebanese students. It should be considered a public health priority with increased tobacco surveillance and legislation. Widespread educational and policy interventions might help denormalize the social acceptability of WTS. Meanwhile, more research is needed to understand the changing paradigm of WTS epidemiology and the health outcomes among young smokers. Copyright © 2015 The Royal Society for Public Health.

    This document describes the exposure time calculator for the Wide-Field Infrared Survey Telescope (WFIRST) high-latitude survey. The calculator works in both imaging and spectroscopic modes. In addition to the standard ETC functions (e.g. background and SN determination), the calculator integrates over the galaxy population and forecasts the density and redshift distribution of galaxy shapes usable for weak lensing (in imaging mode) and the detected emission lines (in spectroscopic mode). The source code is made available for public use.

  11. Initial Blackbeard power survey results

    Murphy, T.; Devenport, J.; Holden, D.

    1996-06-01

    The Blackbeard broadband VHF radio receiver is in low-earth orbit aboard the ALEXIS satellite. The receiver has been used to measure the transmitted power in four VHF bands (55.2-75.8, 28.0-94.8, 132.3-152.2, and 107.7-166.0 MHz) over quiet and noisy parts of the earth. The authors present the results of the survey and discuss their implications. They find that there are remote ocean areas over which the observed spectrum is largely free of man-made interference, but that the spectrum over most of the earth is dominated by broadcast VHF signals. The signal characteristics observed over a given area are quite constant when observed at different times of day and at intervals of several weeks to months. It appears that in many cases the bulk of the signal power is coming from a small number of sources.

    Background Exposure to e-cigarette communications (e.g., advertisements, news and entertainment media, and interpersonal discussion) may influence support for smoke-free or vape-free policies. This study examined the socio-demographic correlates of self-reported exposure to e-cigarette communications and their relationships with support for restricting vaping and smoking in public venues. Method Online survey data was collected from a representative sample of U.S. adults (n=1,449) between October and December 2013 (mean age=50 years, 51% female, 8% African-American, 10% Hispanic, 6% other races) and weighted to match the U.S. adult population. We fitted multiple regression models, adjusting for demographic variables, to examine associations between support for policies to restrict vaping and smoking in public venues and self-reported frequency of exposure to e-cigarette communications in the preceding month. We fitted separate models to assess associations between policy support and frequency of exposures weighted by whether each category of e-cigarette communications was perceived as positive or negative. Results Higher self-reported exposure to advertising (B=-.022, p=.006), other media (B=-.022, p=.043), and interpersonal discussion (B=-.071, pExposure to e-cigarette communications was associated with lower support for smoking restrictions in bivariate analyses but was not significant after adjusting for covariates. Conclusion Further research is needed to assess whether messages portraying e-cigarettes as a way to circumvent smoking restrictions from advertisements and other media are influencing public support for vape-free policies. These findings provide empirical evidence to inform the policy debate over regulating specific e-cigarette advertising claims. PMID:25015372

    This report reviews mild gasification processes with respect to processing conditions and configurations. Special emphasis was placed on processes which could be commercialized within five years. Detailed market information was provided by J.E. Sinor concerning markets and economic considerations of the various processing steps. Processing areas studied include coal cleaning; mild gasification; and upgrading of the char, condensables, and hydrocarbon gases. Pros and cons in the different processing areas as well as ''gaps'' in pertinent data were identified and integrated into a detailed process development program. The report begins with a summary of the market assessment and an evaluation of the co-product. The impacts of feed materials and operating parameters--including coal rank, heating rate, pressure, agglomeration, temperature, and feed gas composition--on the co- products and processes were evaluated through a literature survey. Recommendations were made as to the preferred product specifications and operating parameters for a commercial plant. A literature review of mild gasification processes was conducted and evaluated with regard to product specification and operating parameters. Two candidate processes were chosen and discussed in detail with respect to scale-up feasibility. Recommendations were then made to process development needs to further consideration of the two processes. 129 refs., 33 figs., 16 tabs.

    Sample surveys are widely used in the social sciences and business. The news media almost daily quote from them, yet they are widely misused. Using students with prior managerial experience embarking on an MBA course, we show that common sample survey results are misunderstood even by those managers who have previously done a statistics course. In general, they fare no better than managers who have never studied statistics. There are implications for teaching, especially in business schools, as well as for consulting.

    The Arecibo L-Band Feed Array Zone of Avoidance (ALFA ZOA) Deep Survey is the deepest and most sensitive blind Hi survey undertaken in the ZOA. ALFA ZOA Deep will cover about 300 square degrees of sky behind the Galactic plane in both the inner (30 deg < l < 75 deg; b < |2 deg|) and outer (175 deg < l < 207 deg; -2 deg < b < +1 deg) Galaxy, using the Arecibo Radio Telescope. First results from the survey have found 61 galaxies within a 15 square degree area centered on l = 192 deg and b = -2 deg. The survey reached its expected sensitivity of rms = 1 mJy at 9 km/s channel resolution, and is shown to be complete above integrated flux, F_HI = 0.5 Jy km/s. The positional accuracy of the survey is 28 arcsec and detections are found out to a recessional velocity of nearly 19,000 km/s. The survey confirms the extent of the Orion and Abell 539 clusters behind the plane of the Milky Way and discovers expansive voids, at 10,000 km/s and 18,000 km/s. 26 detections (43%) have a counterpart in the li...

First results from the survey have found 61 galaxies within a 15 square degree area centered on l=192^\\circ and b = -2°. The survey reached its expected sensitivity of rms = 1 mJy at 9 km s-1 channel resolution, and is shown to be complete above integrated flux, FHi = 0.5 Jy km s-1. The positional accuracy of the survey is 28″ and detections are found out to a recessional velocity of nearly 19,000 km s-1. The survey confirms the extent of the Orion and Abell 539 clusters behind the plane of the Milky Way and discovers expansive voids, at 10,000 and 18,000 km s-1. Twenty-six detections (43%) have a counterpart in the literature, but only two of these have known redshifts. Counterparts are 20% less common beyond vhel = 10,000 km s-1 and 33% less common at extinctions higher than AB = 3.5 mag. The ALFA ZOA Deep survey is able to probe large scale structure beyond redshifts that even the most modern wide-angle surveys have been able to detect in the ZOA at any wavelength.

  3. Geothermal industry employment: Survey results & analysis

    Energy Technology Data Exchange (ETDEWEB)

    2005-09-01

    The Geothermal Energy Association (GEA) is ofteh asked about the socioeconomic and employment impact of the industry. Since available literature dealing with employment involved in the geothermal sector appeared relatively outdated, unduly focused on certain activities of the industry (e.g. operation and maintenance of geothermal power plants) or poorly reliable, GEA, in consultation with the DOE, decided to conduct a new employment survey to provide better answers to these questions. The main objective of this survey is to assess and characterize the current workforce involved in geothermal activities in the US. Several initiatives have therefore been undertaken to reach as many organizations involved in geothermal activities as possible and assess their current workforce. The first section of this document describes the methodology used to contact the companies involved in the geothermal sector. The second section presents the survey results and analyzes them. This analysis includes two major parts. The first part analyzes the survey responses, presents employment numbers that were captured and describes the major characteristics of the industry that have been identified. The second part of the analysis estimates the number of workers involved in companies that are active in the geothermal business but did not respond to the survey or could not be reached. Preliminary conclusions and the study limits and restrictions are then presented. The third section addresses the potential employment impact related to manufacturing and construction of new geothermal power facilities. Indirect and induced economic impacts related with such investment are also investigated.

    NASA OSIRIS-REx and JAXA Hayabusa 2 sample-return missions have targeted two near-Earth asteroids: (101955) Bennu and (162173) 1999 JU3, respectively. These are primitive asteroids that are believed to originate in the inner belt, where five distinct sources have been identified: four primitive collisional families (Polana, Erigone, Sulamitis, and Clarissa), and a population of low-albedo and low-inclination background asteroids. Identifying and characterizing the populations from which these two NEAs might originate will enchance the science return of the two missions.With this main objective in mind, we initiated in 2010 a spectroscopic survey in the visible and the near-infrared to characterize the primitive collisional families in the inner belt and the low-albedo background population. This is the PRIMitive Asteroids Spectroscopic Survey - PRIMASS. So far we have obtained more than 200 spectra using telescopes located at different observatories. PRIMASS uses a variety of ground based facilities. Most of the spectra have been obtained using the 10.4m Gran Telescopio Canarias (GTC), and the 3.6m Telescopio Nazionale Galileo (TNG), both located at the El Roque de los Muchachos Observatory (La Palma, Spain), and the 3.0m NASA Infrared Telescope Facility on Mauna Kea (Hawai, USA).We present the first results from our on-going survey (de Leon et al. 2015; Pinilla-Alonso et al. 2015; Morate et al. 2015), focused on the Polana and the Erigone primitive families, with visible and near-infrared spectra of more than 200 objects, most of them with no previous spectroscopic data. Our survey is already the largest database of primitive asteroids spectra, and we keep obtaining data on the Sulamitis and the Clarissa families, as well as on the background low-albedo population.

    This article aims to correlate the main results of three large national surveys on Chagas disease (entomologic, seroprevalence and electrocardiographic) carried out in Brazil from late 1970's to early 1980's, which served as baseline for definition of the control measures adopted in the country. The proportion of infected people was much higher in areas where Triatoma infestans, the most efficient vector of Chagas disease among the five principal species involved in transmission at that time, was predominant. Similar result was observed in places where Triatoma sordida was dispersed, mainly in the country's central region, which corresponds to its native area. This finding is due to the coincidence observed in the geographic distribution of both vectors, since T. sordida is not considered to play an important role in transmission. In the Northeastern semi-arid, endemic area for Triatoma brasiliensis and Triatoma pseudomaculata, rates of human infection were much lower, although both vectors may have some relevance in the maintenance of the disease. As for areas with Panstrongylus megistus, human infection varied according to the levels of domiciliation. Whenever domiciled, like in the humid northeastern coastal area, its involvement in transmission can be clearly demonstrated. In some parts of Bahia State it represented the exclusive vector of the disease. Based upon the results of the seroprevalence survey an electrocardiographic study was carried out in 11 Brazilian states, which showed marked differences in the presence of cardiac alterations when comparing different areas of the country.

    Through electronic mail, we surveyed members of an internet support group for emetophobia (fear of vomiting). Respondents were 50 women and 6 men with a mean age of 31 years. Results suggest that, for this sample, emetophobia is a disorder of early onset and chronic course, with highly persistent and intrusive symptoms. Emetophobia is implicated in social, home-marital, and occupational impairment and it causes significant constriction of leisure activities. Nearly half of women avoided or delayed becoming pregnant. About three quarters of respondents have eating rituals or significantly limit the foods they eat. Respondents describe other problems such as depression, panic attacks, social anxiety, compulsions, and frequent history of childhood separation anxiety.

    Full Text Available  Web is a huge information repository covering almost every topic, in which a human user could be interested. As the size and richness of information on the web increases, diversity and complexity of the tasks users tries to perform also increases. With the overwhelming volume of information on the web, the task of finding relevant information related to a specific query or topic is becoming increasingly difficult. Now a day’s commonly used task on internet is web search. User gets variety of related information for their queries. To provide more relevant and effective results to user, Personalization technique is used. Personalized web search refer to search information that is tailored specifically to a person’s interests by incorporating information about query provided. Two general types of approaches to personalizing search results are modifying user’s query and re-ranking search results. Several personalized web search techniques based on web contents, web link structure, browsing history, user profiles and user queries.

    Full Text Available Introduction In the United States, tobacco use is the leading preventable cause of death and disease. The health and cost consequences of tobacco dependence have made treatment and prevention of tobacco use a key priority among multiple stakeholders, including health plans, insurers, providers, employers, and policymakers. In 2002, the third survey of tobacco control practices and policies in health plans was conducted by America’s Health Insurance Plans’ technical assistance office as part of the Addressing Tobacco in Managed Care (ATMC program. Methods The ATMC survey was conducted in the spring of 2002 via mail, e-mail, and fax. A 19-item survey instrument was developed and pilot-tested. Of the 19 items, 12 were the same as in previous years, four were modified to collect more detailed data on areas of key interest, and three were added to gain information about strategies to promote smoking cessation. The sample for the survey was drawn from the 687 plans listed in the national directory of member and nonmember health plans in America's Health Insurance Plans. Results Of the 246 plans in the sample, 152 plans (62% representing more than 43.5 million health maintenance organization members completed the survey. Results show that health plans are using evidence-based programs and clinical guidelines to address tobacco use. Compared to ATMC survey data collected in 1997 and 2000, the 2002 ATMC survey results indicate that more health plans are providing full coverage for first-line pharmacotherapies and telephone counseling for smoking cessation. Plans have also shown improvement in their ability to identify at least some members who smoke. Similarly, a greater percentage of plans are employing strategies to address smoking cessation during the postpartum period to prevent smoking relapse and during pediatric visits to reduce or eliminate children’s exposure to environmental tobacco smoke. Conclusion The results of the 2002 ATMC survey

    The purpose of this paper is to measure patient safety culture in five Belgian general hospitals. Safety culture plays an important role in the approach towards greater patient safety in hospitals. The Patient Safety Culture Hospital questionnaire was distributed hospital-wide in five general hospitals. It evaluates ten patient safety culture dimensions and two outcomes. The scores were expressed as the percentage of positive answers towards patient safety for each dimension. The survey was conducted from March through November 2005. In total, 3,940 individuals responded (overall response rate = 77 per cent), including 2,813 nurses and assistants, 462 physicians, 397 physiotherapists, laboratory and radiology assistants, social workers and 64 pharmacists and pharmacy assistants. The dimensional positive scores were found to be low to average in all the hospitals. The lowest scores were "hospital management support for patient safety" (35 per cent), "non-punitive response to error" (36 per cent), "hospital transfers and transitions" (36 per cent), "staffing" (38 per cent), and "teamwork across hospital units" (40 per cent). The dimension "teamwork within hospital units" generated the highest score (70 per cent). Although the same dimensions were considered problematic in the different hospitals, important variations between the five hospitals were observed. A comprehensive and tailor-made plan to improve patient safety culture in these hospitals can now be developed. Results indicate that important aspects of the patient safety culture in these hospitals need improvement. This is an important challenge to all stakeholders wishing to improve patient safety.

    Medical Simulation Centers are an essential component of our learning infrastructure to prepare doctors and nurses for their careers. Unlike the military and aerospace simulation industry, very little has been published regarding the best practices currently in use within medical simulation centers. This survey attempts to provide insight into the current simulation practices at medical schools, hospitals, university nursing programs and community college nursing programs. Students within the MBA program at Saint Joseph's University conducted a survey of medical simulation practices during the summer 2010 semester. A total of 115 institutions responded to the survey. The survey resus discuss overall effectiveness of current simulation centers as well as the tools and techniques used to conduct the simulation activity

    The Tsinghua University-National Astronomical Observatories of China (NAOC) Transient Survey (TNTS) is an automatic survey for a systematic exploration of optical transients (OTs), conducted with a 60/90 cm Schmidt telescope at Xinglong station of NAOC. This survey repeatedly covers ~ 1000 square degrees of the north sky with a cadence of 3-4 days. With an exposure of 60 s, the survey reaches a limited unfiltered magnitude of about 19.5 mag. This enables us to discover supernovae at their relatively young stages. In this paper, we describe the overall performance of our survey during the first year and present some preliminary results.

    Paz, J.D.; Milliken, R.; Ingram, W.T.; Frank, A.; Atkin, A.

    1987-07-01

    A dosimetric survey of microwave radiation emitted by electrosurgical units used in operating rooms indicated that surgeons expose themselves to levels that may be hazardous, and that ocular exposures are especially high: 20 cm from the active lead, electric field strength at the eye/forehead position was 9.0 X 10(6) V2/M2 for the monopolar unit; and magnetic field strength at this position reached a magnitude of 3.5 A2/M2. These electric and magnetic fields exceeded the TLVs of the American National Standards Institute. The authors concluded that the high levels of microwave radiation generated by electrosurgery devices should receive immediate attention to assess health effects associated with such exposures.

    Full Text Available Appraising projects with intergenerational effects is a complex task, incorporating the issue of bringing future impacts to present value. This is usually achieved by applying the discount factor. However, the choice of discount rate to intergenerational context faces multiple technical and moral problems. The paper analyses a theoretical rationale behind the concept of intergenerational discount rate and preliminary assessment of intergenerational discount rate level in Poland based on survey done in 2012 among Finance & Insurance Faculty students at University of Economics in Katowice showing the decline in the value of discount rates with time.

  18. Comparative international analysis of radiofrequency exposure surveys of mobile communication radio base stations.

    Rowley, Jack T; Joyner, Ken H

    2012-01-01

    This paper presents analyses of data from surveys of radio base stations in 23 countries across five continents from the year 2000 onward and includes over 173,000 individual data points. The research compared the results of the national surveys, investigated chronological trends and compared exposures by technology. The key findings from this data are that irrespective of country, the year and cellular technology, exposures to radio signals at ground level were only a small fraction of the relevant human exposure standards. Importantly, there has been no significant increase in exposure levels since the widespread introduction of 3G mobile services, which should be reassuring for policy makers and negate the need for post-installation measurements at ground level for compliance purposes. There may be areas close to antennas where compliance levels could be exceeded. Future potential work includes extending the study to additional countries, development of cumulative exposure distributions and investigating the possibility of linking exposure measurements to population statistics to assess the distribution of exposure levels relative to population percentiles.

    The Herschel Reference Survey is a SPIRE guaranteed time key project aimed at studying the properties of the interstellar medium of a K-band selected, volume-limited (15 ≤ D ≤ 25 Mpc) complete sample of 322 galaxies spanning a large range in morphological type and stellar mass. We study the far infrared colours of the late-type galaxies of the cluster with the purpose of tracing with an empirical approach the relationships between the shape of the observed spectral energy distribution (SED) and different physical parameters such as the star formation rate, the birthrate parameter (or specific star formation rate), here taken as a tracer of the hardness of the inciding radiation, the intensity of the ionising and non ionising radiation, the metallicity and the Hα and FUV attenuation. We also show that the far infrared shape of the SED cannot be fitted with a modified black body with a fixed grain emissivity parameter β. All this analysis is a brief summary of a work presented in Boselli_etal. (2012).

    Full Text Available Abstract Background There is a lack of data describing the exposure of Malaysian schoolchildren to Secondhand Smoke (SHS. The aim of this study is to identify factors influencing schoolchildren's exposures to SHS in Malaysia. Method This cross-sectional study was carried out to measure salivary cotinine concentrations among 1064 schoolchildren (10-11 years attending 24 schools in Malaysia following recent partial smoke-free restrictions. Parents completed questionnaires and schoolchildren provided saliva samples for cotinine assay. Results The geometric mean (GM salivary cotinine concentrations for 947 non-smoking schoolchildren stratified by household residents' smoking behaviour were: for children living with non-smoking parents 0.32 ng/ml (95% CI 0.28-0.37 (n = 446; for children living with a smoker father 0.65 ng/ml (95% CI 0.57-0.72 (n = 432; for children living with two smoking parents 1.12 ng/ml (95% CI 0.29-4.40 (n = 3; for children who live with an extended family member who smokes 0.62 ng/ml (95% CI 0.42-0.89 (n = 33 and for children living with two smokers (father and extended family member 0.71 ng/ml (95% CI 0.40-0.97 (n = 44. Parental-reported SHS exposures showed poor agreement with children's self-reported SHS exposures. Multiple linear regression demonstrated that cotinine levels were positively associated with living with one or more smokers, urban residence, occupation of father (Armed forces, parental-reported exposure to SHS and education of the father (Diploma/Technical certificate. Conclusions This is the first study to characterise exposures to SHS using salivary cotinine concentrations among schoolchildren in Malaysia and also the first study documenting SHS exposure using salivary cotinine as a biomarker in a South-East Asian population of schoolchildren. Compared to other populations of similarly aged schoolchildren, Malaysian children have higher salivary cotinine concentrations. The partial nature of smoke

    The study is carried out to assess the exposure rate that could contribute to public exposure in a radioiodine ward delay tank facility of Radiotherapy, Oncology and Nuclear Medicine, Department, Hospital Universiti Sains Malaysia (HUSM). The exposure rate at several locations including the delay tank room, doorway and at the public walking route was measured using Victoreen 415P-RYR survey meter. The radioactive level of the 131I waste was measured using Captus 3000 well counting system. The results showed that exposure rate and total count of the delay tank sample increased when the radioiodine ward was fully occupied with patient and reduced when the ward was vacant. Occupancy of radioiodine ward for two consecutive weeks had dramatically increased the exposure rate around the delay tank and radioactive level of 131I waste. The highest exposure rate and radioactive level was recorded when the ward was occupied for two consecutive weeks with 177.00 µR/h and 58.36 kcpm respectively. The exposure rate decreased 15.76 % when the door of the delay tank room was closed. The exposure rate at public walking route decreased between 15.58 % and 36.92 % as the distance increased between 1 and 3 m.

    The study of corrosion products from short term atmospheric exposures of carbon steel, is very important to understand the processes that lead to corrosion of steels, and ultimately improve the performance of such steel in highly corrosive environments. Many regions along the Gulf of Mexico have extremely corrosive environments due to high mean annual temperature, humidity, time-of-wetness and every high atmospheric pollutants. The process the formation of corrosion products resulting from short term exposure of carbon steel, both as a function of environmental conditions and exposure time, has been investigated. Two sets of coupons were exposed at marine and marine locations, in Campeche, Mexico. Each set was exposed between 1 and 12 months to study the corrosion as a function of time. During the exposure periods, the relative humidity, rainfall, mean temperature, wind speed and wind direction were monitored along with the chloride and sulfur dioxide concentrations in the air. The corroded coupons were analyzed by Moessbauer, Raman, Infrared spectroscopies and X-ray diffraction in order to completely identify the oxides and map their location in the corrosion coating. Scattering and transmission Moessbauer analysis showed some layering of the oxides with lepidocrocite and akaganeite closer to the surface. The fraction of akaganeite phase increased at sites with higher chloride concentrations. A detailed analysis on the development of the oxide phases as a function of exposure time and environmental conditions will be presented. (Author)

  9. Differential pathologies resulting from sound exposure: Tinnitus vs hearing loss

    Science.gov (United States)

    Longenecker, Ryan James

    the acoustic startle reflex show that after sound exposure the magnitude of startle responses decrease in most mice, to varying degrees. Lastly, PPI audiometry was able to detect specific behavioral threshold deficits for each mouse after sound exposure. These deficits persist past initial threshold shifts and are able to detect frequency specific permanent threshold shifts. The third specific aim examined hyperactivity and increased bursting activity in the inferior colliculus after sound exposure in relation to tinnitus and hearing loss. Spontaneous firing rates were increased in all mice after sound exposure regardless of behavioral evidence of tinnitus. However, abnormal increased bursting activity was not found in the animals identified with tinnitus but was exhibited in a mouse with broad-band severe threshold deficits. CBA/CaJ mice are a good model for both tinnitus development and noise-induced hearing loss studies. Hyperactivity which was evident in all exposed animals does not seem to be well correlated with behavioral evidence of tinnitus but more likely to be a general result of acoustic over exposure. Data from one animal strongly suggest that wide-spread severe threshold deficits are linked to an elevation of bursting activity predominantly ipsilateral to the side of sound exposure. This result is intriguing and should be followed up in further studies. Data obtained in this study provide new insights into underlying neural pathologies following sound exposure and have possible clinical applications for development of effective treatments and diagnostic tools for tinnitus and hearing loss.

    A countrywide survey of radon concentrations in Estonian dwellings was carried out during the period 1998-2001. The survey formed a part of the cooperation program on radiation protection between the Estonian Radiation Protection (Kiirguskeskus) Centre and the Swedish Radiation Protection Authority (SSI). The survey included measurements in a number of dwellings representative for Estonia in detached houses and multifamily buildings (only dwellings on the bottom floor were included in the survey). Altogether, radon concentrations were measured in 515 dwellings, a number large enough to be statistically significant. All measurements were made with alphatrack film detectors of the same type that SSI uses in Sweden. The measurements were made during a 2-3 month period during the winter half-year. Two detectors were used in each dwelling. In Estonia there are 0.17 million dwellings in detached houses and 0.45 million in multi apartment buildings. Of the 1.26 million inhabitants in Estonia. 0.36 million live in detached houses and 0.90 million in multi apartment buildings. Most of the latter were built during the Soviet occupation. Of the dwellings in multifamily buildings 30 % are assumed to be situated on the first floor. The mean radon concentration in dwellings in detached hoses, according to the survey results, is 103 Bq/m{sup 3}, in dwellings on the bottom floor in multi apartment buildings it is 78 Bq/m{sup 3}. In 1% of the dwellings the radon concentration exceeded 400 Bq/m{sup 3}. The highest radon concentration found in the study was 1040 Bq/m{sup 3}. Based on the assumption that the average radon concentration in the dwellings in multi-apartment buildings that are not situated on the bottom floor is 30 Bq/m{sup 3}, and that these dwellings constitute 70% of all dwellings in multi apartment buildings, the mean radon concentration in dwellings in multi apartment buildings is calculated to be 44 Bq/m{sup 3}. The mean value for all Estonia dwellings is calculated

    The fact that the risks deriving from different activities involving the same radiation exposure are seen very differently by a single population is a highly significant one. Exactly identical risks are considered oppositely, depending on the origin of radiation (whether produced by medical applications or by nuclear power plants, resulting from natural radiation or from artificial radiation). It appears as if there was good radiation and bad radiation..{exclamation_point} One of the purposes of the paper is the discussion of causes. The acceptance of a given risk by a certain section of the population is closely related to the benefits that the group expects to receive-either consciously or unconsciously-from the activity producing the risk. Consequently, an analysis of the factors influencing the eventual rejection of a practice should explore not only fears, but also hopes...{exclamation_point} On the basis of a risk-perception survey carried out in a population sector attending hospitals-including both patients and physicians-, a prior objective analysis of the results obtained was performed and, later on, the various statements by those surveyed were studied. The design of the survey allowed for a comparative assessment of the perception of different risks depending on the people's educational and social level. An epistemological study was made on the validity involved in the use of the data resulting from the survey, so as to reach different conclusions. The population's opinion about the capacity for response, the qualification and the mitigation means available to the State authorities in order to face an eventual radiological emergency plays a leading role in risk perception. In an analysis of the relevant factors involved in risk and benefits perception by the population (in the real world), attention must be paid to the existence of organized opinion groups representing the interest of a given sector. Of course, the population's confidence

    The U.S. Fish and Wildlife Service (Service) collaborated with the U.S. Geological Survey to conduct a national survey of visitors regarding their experiences on national wildlife refuges. The survey was conducted to better understand visitor needs and experiences and to design programs and facilities that respond to those needs. The survey results will inform Service performance planning, budget, and communications goals. Results will also inform Comprehensive Conservation Plan (CCPs), Visitor Services, and Transportation Planning processes. The survey was conducted on 53 refuges across the National Wildlife Refuge System (Refuge System) to better understand visitor needs and experiences and to design programs and facilities that respond to those needs. A total of 14,832 visitors agreed to participate in the survey between July 2010 and November 2011. In all, 10,233 visitors completed the survey for a 71% response rate. This report provides a summary of visitor and trip characteristics; visitor opinions about refuges and their offerings; and visitor opinions about alternative transportation and climate change, two Refuge System topics of interest. The Refuge System, established in 1903 and managed by the Service, is the leading network of protected lands and waters in the world dedicated to the conservation of fish, wildlife and their habitats. There are 556 National Wildlife Refuges and 38 wetland management districts nationwide, encompassing more than 150 million acres. The Refuge System attracts more than 45 million visitors annually, including 25 million people per year to observe and photograph wildlife, over 9 million to hunt and fish, and more than 10 million to participate in educational and interpretation programs. Understanding visitors and characterizing their experiences on national wildlife refuges are critical elements of managing these lands and meeting the goals of the Refuge System. These combined results are based on surveying at 53 participating

    Full text of publication follows: UK policy on the control of radiation exposure via routine discharges from nuclear licensed sites has long been based on ICRP recommendations that embody the principles of justification of practices, optimisation of protection, and dose limitation. Radiological protection of the public is based on the concept of a critical group of individuals. This group is defined as those people who, as a result of the area they reside and their habits, receive the highest radiation dose due to the operations of a site. Therefore, if the dose to this critical group is acceptable in relation to relevant dose limits and constraints, then other members of the public will receive lower doses. Thus, the principle of critical groups provides overall protection for the public. Surveys to determine local habits involve an integrated methodology, whereby the potential radioactive exposure pathways from liquid and gaseous discharges and direct radiation from the site are investigated. Surveys to identify these habits must be undertaken rigorously for consistency, and have been known to reveal unexpected pathways of radiation exposure. Pathways typically include consumption of local foodstuffs and external exposure. Furthermore, a number of critical groups ma y be identified within a single survey area if the habits of one group do not adequately describe those of the other inhabitants of the area. Survey preparation involves the initial identification of high producers and consumers of local foods in a geographically defined area surrounding the nuclear facility. Pathways can be broken down into three general groups, which include exposure arising from; 1) Terrestrial (gaseous) discharges surveyed within 5 km of the site 2) Direct radiation surveyed within 1 km of the site 3) Aquatic (liquid) discharges surveyed within local areas affected by the discharges, including seas, rivers and sewage works. The survey fieldwork involves interviewing members of the

  15. Toxicoepidemiology in Zimbabwe: admissions resulting from exposure to paraffin (kerosene).

    Paraffin (kerosene) ingestion is the most common form of childhood poisoning in most developing countries. Despite this, there is a paucity of toxicoepidemiological data which could potentially be used in measures to reduce preventable exposures. This article reports on the patterns of hospital admissions resulting from paraffin exposure in Zimbabwe. All cases of paraffin ingestion admitted to eight major referral hospitals in Zimbabwe from January 1998 to December 1999 (inclusive), were identified using ICD-9 codes and ward registers and relevant information recorded on a standard data collection sheet. There were a total of 327 admissions due to oral exposure to paraffin. This represented 11.8% of all the poisoning admissions to the eight study hospitals. Most exposures (300; 91.7%) occurred accidentally, with only 6.7% resulting from deliberate ingestion of the chemical. The median age on admission was 2 years (interquartile range [IQR] 1-2 yrs) with over 85% of cases in the 0-5 year age range and less than 10% above the age of 12 years. The median age on admission was much higher for deliberate self poisoning (23 yrs; IQR 19-26 yrs) compared to that for accidental poisoning (1.5 yrs; IQR 1-2 yrs). Accidental poisoning from paraffin occurred throughout the year. Over three-quarters of patients received an antibiotic either alone, or in combination with another antibiotic or drug. Paracetamol (24.3%) was the next most commonly encountered treatment. The case fatality rate (CFR) was therefore 0.3 deaths per 100 admissions (95% Confidence Interval 0.0-1.7). Paraffin ingestion remains an important cause of poisoning morbidity in Zimbabwe throughout the year, particularly in children. Clinical management appears adequate with a low mortality, although there may be overuse of prophylactic antibiotics. Further study specific to this area is warranted to prevent unnecessary antibiotic use and wastage of resources.

    We present preliminary results for the photometric time-series data obtained with the BOKS survey (see BOKS I poster Feldmeier et al.). The BOKS survey covers about 1 square degree in the constellation of Cygnus. We obtained nearly 2000 SDSS r-band images spanning a total time period of 39 days. Each point source in our BOKS survey is also present in the single epoch, 7-color photometric survey catalogue being produced by the NASA Discovery program Kepler mission. Light curves of approximately 60,000 point sources, spanning r=14 to 20, are examined and discussed. We will present variability demographics for the BOKS survey including characterization of the light curves into variable classes based on type, color, amplitude, and any extra-solar planet transit candidates.

Using data from a real social science study as a baseline, three strategies that participants might use to farm are studied by Monte Carlo simulation. Findings show that farming influences survey results and can cause both statistical hypotheses testing Type I (false positive and Type II (false negative errors in unpredictable ways.

  2. Titanium-Water Thermosyphon Gamma Radiation Exposure and Results

    Titanium-water thermosyphons are being considered for use in heat rejection systems for fission power systems. Their proximity to the nuclear reactor will result in some gamma irradiation. Noncondensable gas formation from radiation-induced breakdown of water over time may render portions of the thermosyphon condenser inoperable. A series of developmental thermosyphons were operated at nominal operating temperature under accelerated gamma irradiation, with exposures on the same order of magnitude as that expected in 8 years of heat rejection system operation. Temperature data were obtained during exposure at three locations on each thermosyphon: evaporator, condenser, and condenser end cap. Some noncondensable gas was evident; however, thermosyphon performance was not affected because the noncondensable gas was compressed into the fill tube region at the top of the thermosyphon, away from the heat rejecting fin. The trend appeared to be an increasing amount of noncondensable gas formation with increasing gamma irradiation dose. Hydrogen is thought to be the most likely candidate for the noncondensable gas and hydrogen is known to diffuse through grain boundaries. Post-exposure evaluation of one thermosyphon in a vacuum chamber and at temperature revealed that the noncondensable gas diffused out of the thermosyphon over a relatively short period of time. Further research shows a number of experimental and theoretical examples of radiolysis occurring through gamma radiation alone in pure water.

  3. Cetacean behavioral responses to noise exposure generated by seismic surveys: how to mitigate better?

    Full Text Available Cetaceans use sound in many contexts, such as in social interactions, as well as to forage and to react in dangerous situations. Little information exists to describe how they respond physically and behaviorally to intense and long-term noise levels. Effects on cetaceans from seismic survey activities need to be understood in order to determine detailed acoustic exposure guidelines and to apply appropriated mitigation measures. This study examines direct behavioral responses of cetaceans in the southern Mediterranean Sea during seismic surveys with large airgun arrays (volume up to 5200 ci used in the TOMO-ETNA active seismic experiment of summer 2014. Wide Angle Seismic and Multi-Channel Seismic surveys had carried out with refraction and reflection seismic methods, producing about 25,800 air-gun shots. Visual monitoring undertaken in the 26 daylights of seismic exploration adopted the protocol of the Joint Nature Conservation Committee. Data recorded were analyzed to examine effects on cetaceans. Sighting rates, distance and orientation from the airguns were compared for different volume categories of the airgun arrays. Results show that cetaceans can be disturbed by seismic survey activities, especially during particularly events. Here we propose many integrated actions to further mitigate this exposure and implications for management.

    The survey provided by the College of American Pathologists (CAP) is chosen as one of the proficiency testing programs in Japan, and, recently, the numbers of participating facilities have increased. CAP provides 754 programs, and more than 1,000 tests were provided in 2014. Materials are translated as the "CAP global inter-laboratory comparison program" under the instruction of the Japanese Society of Laboratory Medicine (JSLM) selected from CAP surveys in Japan, and 68 programs and 261 items are provided. The total number of participating facilities was 174. CAP itself and the other services CAP provides are not well-known, while recognition of "the CAP survey as the proficiency test" has increased. The question "What is CAP and the CAP survey" was analyzed as a result of the questionnaire surveys conducted in 2014, and the advantage of the CAP survey and how to utilize it were considered. A questionnaire survey was conducted about the CAP survey for Japanese participants in 2014. Fifty-three questions were asked about their satisfaction level, intended use, and improvement. Eighty replies were analyzed. As a result, most CAP survey participants are satisfied. They intend to mainly use the CAP survey for their quality control. Furthermore, they can continuously monitor their systems throughout all testing phases as the survey has numbers of shipments a year and several specimens per each mailing. This helps in laboratory performance improvement. The Evaluation and Participant Summary (PSR) also effectively improves the laboratories' performance. CAP-accredited laboratories are required to participate in all survey programs concerning the test menu which they provide. Therefore, they have become accustomed to reviewing the evaluation and performing self-evaluation with a high usage rate of the Evaluation and PSR of the CAP survey. The questionnaire proved that performing the CAP survey properly enhanced the laboratories' quality control, and this meets the

    Human industrial activities have left behind a legacy of ecosystems strongly impacted by a wide range of contaminants, including radionuclides. Phyto-toxic effects of acute impact are well known, but the consequences of long-term chronic exposure to low pollutant concentrations is neither well understood nor adequately included in risk assessments. To understand effects of real-world contaminant exposure properly we must pay attention to what is actually going on in the field. However, for many wildlife groups and endpoints, there are no, or very few, studies that link accumulation, chronic exposure and biological effects in natural settings. To fill the gaps, results of field studies carried out on different plant species (winter rye and wheat, spring barley, oats, Scots pine, wild vetch, crested hair-grass) in various radioecological situations (nuclear weapon testing, the Chernobyl accident, uranium and radium processing) to investigate effects of long-term chronic exposure to radionuclides are discussed. Because each impacted site developed in its own way due to a unique history of events, the experience from one case study is rarely directly applicable to another situation. In spite of high heterogeneity in response, we have detected several general patterns. Plant populations growing in areas with relatively low levels of pollution are characterized by the increased level of both cytogenetic alterations and genetic diversity. Accumulation of cellular alterations may afterward influence biological parameters important for populations such as health and reproduction. Presented data provide evidence that in plant populations inhabiting heavily contaminated territories cytogenetic damage were accompanied by decrease in reproductive ability. In less contaminated sites, because of the scarcity of data available, it is impossible to establish exactly the relationship between cytogenetic effects and reproductive ability. Radioactive contamination of the plants

  6. Speak Up Speak Out Coalition Survey Results | Science ...

    Science.gov (United States)

    Comprehensive planning is a visionary planning process that integrates community values and land use policy. The Mayor of Duluth, Minnesota, directed the inclusion of two new values into the City’s comprehensive planning process to direct the community’s future, process: health and fairness. In order to understand the meanings of health and fairness that residents of the city hold, the Community Planning Department included questions in a city-wide survey of planning priorities. As a community organization reviewed the survey results that would inform the new directives, they realized that overburdened communities were underrepresented in the survey responses. To address this deficiency, the community organization asked the City of Duluth if they could conduct a survey of the underrepresented voices to ensure their input was included in the process. The Health in All Policies Coalition contacted the USEPA Office of Research and Development in Duluth, MN at the advice of the Planning Department. The support USEPA provided ensured that the Coalition could make recommendations to the City of Duluth based on systematically collected and analyzed data. This presentation will share the results of the survey. This presentation of the Speak Up Speak Out survey data represents support for local decision-making, technical assistance and data analysis. The data were collected and analyzed through advice and consultation with USEPA Office of Research and Development, an

    There is a need for objective data on the exposure of spraymen to pesticides in agriculture in order to assess minimum requirements for practicable protection in tropical areas. To provide data, a survey was carried out in the Sudan on spraymen using dimethoate. No cholinesterase depressions were found and the calculated dose received by each man per day was within safe limits in the circumstances of this survey. Respiratory exposure was only a minor part of total exposure. The methodology of such surveys is discussed and the need for the use of a standard protocol is emphasized. PMID:1088104

    2015-12-01

    Full Text Available Nearly 25 years ago, a “Zooarchaeology Practitioner Survey” was distributed via conventional mail to individuals in the USA and Canada and received 122 responses over a period of several months in 1991. Now, a revised “Demographics in Zooarchaeology Survey” provides an update to  those data and assesses the current state of the field. The 2014 survey remained open for 3 months and received 288 responses from practitioners worldwide. Global participation was made possible by hosting the survey online. Key findings of the 1991 survey included disparities in employment rank for women despite similar levels of degree level attainment as men, a point which the 2014 survey sought to investigate. This trend appears to persist for those without the PhD and at the highest levels of income for those holding a PhD. In addition, the recent survey asked participants about their racial or ethnic identity in order to evaluate the demographic diversity of the discipline beyond sex, age, and nationality. Data regarding topical and geographic research area were also collected and reflect a subtle bias towards working with mammals and a focus on research questions grounded in prehistory in Europe and North America, followed by Australia and Southwest Asia. Results are compared with those of the earlier survey and membership information from the International Council for Archaeozoology.

    We present preliminary results of our initial selection of emission-line galaxy candidates from the KPNO International Spectroscopic Survey (KISS) project. KISS is a wide-field survey for extragalactic emission-line objects being carried out with the Burrell Schmidt at Kitt Peak. It combines the classical objective-prism technique for finding strong-lined star-forming galaxies and AGNs with the use of CCD detectors and automated reduction software to enhance and stream-line the survey process. With its good depth plus significant areal coverage, KISS will be a powerful tool for the study of activity in galaxies. Our first survey strip covers 102 square degrees across the North Galactic Cap. The data consist of deep (to B = 20) objective-prism images, deep direct images in both B and V, and small-format photometric calibration images of each field. The objective-prism data cover two spectral regions: red spectra which include the Hα line, and blue spectra with the [O III]lambda 5007 line. Only results from analyzing the red spectra are presented here. The survey technique used for KISS is extremely successful. Our red spectra yield an average of 18 emission-line galaxy candidates per square degree, which is 180 times higher than the Markarian survey and 32 times the surface density of the Gallego et al. survey. Our direct images provide accurate photometry for all candidates, while rough redshifts and line strengths can be measured from the objective-prism spectra. We present an analysis of the completeness limits of the survey as well as the physical characteristics of the candidate galaxies, such as their luminosity, color, and redshift distributions. Examples of newly discovered emission-line galaxies are shown. The selection function of the survey can be accurately determined from the survey data, allowing us to utilize this large sample for performing statistical studies such as the determination of luminosity functions (B band and Hα ) and measurement of the

    The National Wildlife Refuge System (Refuge System), established in 1903 and managed by the U.S. Fish and Wildlife Service (Service), is the leading network of protected lands and waters in the world dedicated to the conservation of fish, wildlife and their habitats. There are 560 national wildlife refuges and 38 wetland management districts nationwide, encompassing more than 150 million acres. The Refuge System attracts nearly 45 million visitors annually, including 34.8 million people who observe and photograph wildlife, 9.6 million who hunt and fish, and nearly 675,000 teachers and students who use refuges as outdoor classrooms. Understanding visitor perceptions of refuges and characterizing their experiences on refuges are critical elements of managing these lands and meeting the goals of the Refuge System. The Service collaborated with the U.S. Geological Survey to conduct a national survey of visitors regarding their experiences on national wildlife refuges. The purpose of the survey was to better understand visitor experiences and trip characteristics, to gauge visitors’ levels of satisfaction with existing recreational opportunities, and to garner feedback to inform the design of programs and facilities. The survey results will inform performance, planning, budget, and communications goals. Results will also inform Comprehensive Conservation Plans (CCPs), visitor services, and transportation planning processes. This Data Series consists of 25 separate data files. Each file describes the results of the survey for an individual refuge and contains the following information: • Introduction: An overview of the Refuge System and the goals of the national surveying effort. • Methods: The procedures for the national surveying effort, including selecting refuges, developing the survey instrument, contacting visitors, and guidance for interpreting the results.• Refuge Description: A brief description of the refuge location, acreage, purpose, recreational

    Full Text Available Abstract Background Within the field of renal transplantation there is a lack of qualified and trainee surgeons and a shortage of donated organs. Any steps to tackle these issues should, in part, be aimed at future doctors. Methods A questionnaire was distributed to final year students at a single medical school in the UK to assess their exposure to and knowledge of renal transplantation. Results Although 46% of responding students had examined a transplant recipient, only 14% had ever witnessed the surgery. Worryingly, 9% of students believed that xenotransplantation commonly occurs in the UK and 35% were unable to name a single drug that a recipient may need to take. Conclusions This survey demonstrates a lack of exposure to, and knowledge of, the field of renal transplantation. Recommendations to address the problems with the recruitment of surgeons and donation of organs, by targeting medical students are made.

    We present results for the first three years of OzDES, a six-year program to obtain redshifts for objects in the Dark Energy Survey (DES) supernova fields using the 2dF fibre positioner and AAOmega spectrograph on the Anglo-Australian Telescope. OzDES is a multi-object spectroscopic survey targeting multiple types of targets at multiple epochs over a multi-year baseline, and is one of the first multi-object spectroscopic surveys to dynamically include transients into the target list soon after their discovery. At the end of three years, OzDES has spectroscopically confirmed almost 100 supernovae, and has measured redshifts for 17,000 objects, including the redshifts of 2,566 supernova hosts. We examine how our ability to measure redshifts for targets of various types depends on signal-to-noise, magnitude, and exposure time, finding that our redshift success rate increases significantly at a signal-to-noise of 2 to 3 per 1-A° ngstrom bin. We also find that the change in signal-to-noise with exposure time closely matches the Poisson limit for stacked exposures as long as 10 hours.We use these results to predict the redshift yield of the full OzDES survey, as well as the potential yields of future surveys on other facilities such as 4MOST, PFS, and MSE. This work marks the first OzDES data release, comprising 15,327 redshifts. OzDES is on target to obtain over 30,000 redshifts over the six-year duration of the survey, including a yield of approximately 5,700 supernova host-galaxy redshifts.

    We present the selection algorithm and anticipated results for the Time Domain Spectroscopic Survey (TDSS). TDSS is an Sloan Digital Sky Survey (SDSS)-IV Extended Baryon Oscillation Spectroscopic Survey (eBOSS) subproject that will provide initial identification spectra of approximately 220,000 luminosity-variable objects (variable stars and active galactic nuclei across 7500 deg{sup 2} selected from a combination of SDSS and multi-epoch Pan-STARRS1 photometry. TDSS will be the largest spectroscopic survey to explicitly target variable objects, avoiding pre-selection on the basis of colors or detailed modeling of specific variability characteristics. Kernel Density Estimate analysis of our target population performed on SDSS Stripe 82 data suggests our target sample will be 95% pure (meaning 95% of objects we select have genuine luminosity variability of a few magnitudes or more). Our final spectroscopic sample will contain roughly 135,000 quasars and 85,000 stellar variables, approximately 4000 of which will be RR Lyrae stars which may be used as outer Milky Way probes. The variability-selected quasar population has a smoother redshift distribution than a color-selected sample, and variability measurements similar to those we develop here may be used to make more uniform quasar samples in large surveys. The stellar variable targets are distributed fairly uniformly across color space, indicating that TDSS will obtain spectra for a wide variety of stellar variables including pulsating variables, stars with significant chromospheric activity, cataclysmic variables, and eclipsing binaries. TDSS will serve as a pathfinder mission to identify and characterize the multitude of variable objects that will be detected photometrically in even larger variability surveys such as Large Synoptic Survey Telescope.

    Despite President Obama's well-publicized excursion to Kotzebue in 2015 - the first presidential visit to the US Arctic - most of the public remains unaware that their country has any inhabited Arctic territory. This striking result emerged from two nationwide surveys in 2016 that assessed public knowledge and perceptions about the changing polar regions. Other questions tested knowledge about polar geography and conditions, sought perceptions on the importance of global impacts such as sea level or extreme weather, and asked for opinions about trusted information sources (scientists, TV news, websites, etc.) and preferred mitigation policies. With an oversampling of Alaska residents, the POLES survey allows comparisons between perceptions of Alaska residents (including rural Alaska) and people from the other 49 states. It also supports analysis of relationships among knowledge, opinions, information sources, and individual respondent characteristics. We take a first look at results, analysis and interpretation of this unique new polar-oriented survey. Image: "Which country has territory with thousands of people living north of the Arctic Circle? US, China, Estonia, Britain, or none of these?" Graph shows results from a July 2016 pretest with 523 interviews; full results from two nationwide surveys, including Alaska/49-state comparisons, will be presented at AGU.

    Environmental surveys yield three principal products: maps, a set of data tables, and a textual report. The relationships between these three elements, however, are often cumbersome to present, making full use of all the information in an integrated and systematic sense difficult. The published paper report is only a partial solution. Modern developments in computing, particularly in cartography, GIS, and hypertext, mean that it is increasingly possible to conceive of an easier and more interactive approach to the presentation of such survey results. Here, we present such an approach which links map and tabular datasets arising from a vegetation survey, allowing users ready access to a complex dataset using dynamic mapping techniques. Multimedia datasets equipped with software like this provide an exciting means of quick and easy visual data exploration and comparison. These techniques are gaining popularity across the sciences as scientists and decision-makers are presented with increasing amounts of diverse digital data. We believe that the software environment actively encourages users to make complex interrogations of the survey information, providing a new vehicle for the reader of an environmental survey report.

    The Deep Ecliptic Survey is a project whose goal is to survey a large area of the near-ecliptic region to a faint limiting magnitude (R ~ 24) in search of objects in the outer solar system. We are collecting a large homogeneous data sample from the Kitt Peak Mayall 4-m and Cerro Tololo Blanco 4-m telescopes with the Mosaic prime-focus CCD cameras. Our goal is to collect a sample of 500 objects with good orbits to further our understanding of the dynamical structure of the outer solar system. This survey has been in progress since 1998 and is responsible for 272 designated discoveries as of March 2003. We summarize our techniques, highlight recent results, and describe publically available resources.

    The results of a survey of 54 persons with upper limb amputations who anonymously completed a questionnaire on an Internet homepage are presented. The survey ran for four years and the participants were divided into groups of females, males, and children. It was found that the most individuals employ their myoelectric hand prosthesis for 8 hours or more. However, the survey also revealed a high level of dissatisfaction with the weight and the grasping speed of the devices. Activities for which prostheses should be useful were stated to include handicrafts, personal hygiene, using cutlery, operation of electronic and domestic devices, and dressing/undressing. Moreover, additional functions, e.g., a force feedback system, independent movements of the thumb, the index finger, and the wrist, and a better glove material are priorities that were identified by the users as being important improvements the users would like to see in myoelectric prostheses.

    Full Text Available Background. Large-scale poisonings caused by methyl mercury (MeHg have occurred in Japan (Minamata in the 1950s and Niigata in the 1960s and Iraq (in the 1970s. The current WHO neurological risk standard for adult exposure (hair level: 50 μg/g was based partly on evidence from Niigata which did not consider any cases who were diagnosed later and/or exposed to low level of MeHg (hair mercury level less than 50 μg/g. Methods. Early in the Niigata epidemic in June 1965 there were two extensive surveys. From these two surveys, we examined 103 adults with hair mercury measurement who consulted two medical institutions. We compared the prevalence and the distribution of neurological signs related to MeHg poisoning between exposure categories. Result. We found 48 subjects with neurological signs related to MeHg poisoning who had hair mercury concentration less than 50 μg/g. Among the neurological signs, sensory disturbance of the bilateral distal extremities was observed more frequently, followed by disequilibrium, hearing impairment, and ataxia, in groups with hair MeHg concentration both below 50 μg/g and over 50 μg/g. Conclusion. The present study suggests the possibility that exposure to MeHg at levels below the current WHO limits could cause neurologic signs, in particular, sensory disturbance.

    The growing use of social media is transforming the way health care professionals (HCPs) are communicating. In this changing environment, it could be useful to outline the usage of social media by radiologists in all its facets and on an international level. The main objective of the RANSOM survey was to investigate how radiologists are using social media and what is their attitude towards them. The second goal was to discern differences in tendencies among American and European radiologists. An international survey was launched on SurveyMonkey ( https://www.surveymonkey.com ) asking questions about the platforms they prefer, about the advantages, disadvantages, and risks, and about the main incentives and barriers to use social media. A total of 477 radiologists participated in the survey, of which 277 from Europe and 127 from North America. The results show that 85 % of all survey participants are using social media, mostly for a mixture of private and professional reasons. Facebook is the most popular platform for general purposes, whereas LinkedIn and Twitter are more popular for professional usage. The most important reason for not using social media is an unwillingness to mix private and professional matters. Eighty-two percent of all participants are aware of the educational opportunities offered by social media. The survey results underline the need to increase radiologists' skills in using social media efficiently and safely. There is also a need to create clear guidelines regarding the online and social media presence of radiologists to maximize the potential benefits of engaging with social media.

    The aim of this pilot project was to investigate the occurrence of occupational exposure to blood and body fluids in registered physiotherapists in Western Australia. Surveys were sent to physiotherapists with questions regarding personal background, exposure characteristics, and contributing factors included. Descriptive statistical methods were used to identify the area of practice posing the highest risk of exposure to physiotherapists. The authors found that 56.1% of surveyed physiotherapists recorded one or more exposures within the past 5 years. Work in hospitals was found to carry the highest rate of exposure for the physiotherapy profession. Other areas of practice, including community work, private practice, nursing homes/hostels, and work at sporting events carry comparable but lower risks of exposure. In private practice, 50% of exposures were associated with acupuncture. In nursing homes, 60% of exposures were brought on by exposure to contaminated materials, whereas in the community setting most exposures (64%) were attributed to unpredictable/uncontrollable situations. At sporting events, 90% of all exposures were associated with already existing sources of blood and body fluids (wounds). Within the hospital setting, the 3 dominant immediate causes reported were unpredictable situations (33.3%), existing sources (28.4%), and procedural causes (22.2%). The use of personal protective equipment for prevention of exposure is investigated and discussed. Data collected for this survey were not enough to draw conclusive assumptions regarding hazard management. A repeat of this study on a larger scale may provide physiotherapists with the tools and knowledge to minimize the likelihood of exposure and harm arising from exposure.

    Electromagnetic fields (EMFs) include everything from cosmic rays through visible light to the electric and magnetic fields associated with electricity. While the high frequency fields have sufficient energy to cause cancer, the question of whether there are human health hazards associated with communication radiofrequency (RF) EMFs and those associated with use of electricity remains controversial. The issue is more important than ever given the rapid increase in the use of cell phones and other wireless devices. This review summarizes the evidence stating that excessive exposure to magnetic fields from power lines and other sources of electric current increases the risk of development of some cancers and neurodegenerative diseases, and that excessive exposure to RF radiation increases risk of cancer, male infertility, and neurobehavioral abnormalities. The relative impact of various sources of exposure, the great range of standards for EMF exposure, and the costs of doing nothing are also discussed.

  10. The First Results from the DESK Survey (Abstract)

    2016-06-01

    (Abstract only) Young stellar objects (YSOs) are typically surrounded by protoplanetary circumstellar disks. One way to probe the size, mass, and composition of these disks is to observe a star being eclipsed by its own disk. So far only a few of these events have been discovered and analyzed in the literature. New wide-field time domain surveys are an ideal tool to search for rare eclipse events, depending on the coverage, cadence, and baseline of the survey. The Kilodegree Extremely Little Telescope (KELT) exoplanet survey covers a large portion of the sky, including a significant fraction of the galactic plane. Using time-series photometry from KELT we are looking for disk-eclipsing events, specifically in young stellar associations. To date, we have discovered three previously unknown large dimming events around the young stars RW Aurigae, V409 Tau, and TYC 2505-672-1. We attribute the dimming of RW Aurigae to its tidally disrupted disk, while for V409 Tau the dimming is interpreted to be caused by a feature, possibly a warp or perturbation, in its nearly edge-on circumstellar disk. TYC 2505-672-1 appears to be similar to epsilon Aurigae, with an M-giant being eclipsed every ~69 years by a white dwarf with an accretion disk surrounding it. I will describe our results and discuss how we are planning to search for these kinds of objects in future surveys such as LSST.

    2008-03-01

    Full Text Available Abstract Background Lack of methodological rigor can cause survey error, leading to biased results and suboptimal public health response. This study focused on the potential impact of 3 methodological "shortcuts" pertaining to field surveys: relying on a single source for critical data, failing to repeatedly visit households to improve response rates, and excluding remote areas. Methods In a vaccination coverage survey of young children conducted in the Commonwealth of the Northern Mariana Islands in July 2005, 3 sources of vaccination information were used, multiple follow-up visits were made, and all inhabited areas were included in the sampling frame. Results are calculated with and without these strategies. Results Most children had at least 2 sources of data; vaccination coverage estimated from any single source was substantially lower than from all sources combined. Eligibility was ascertained for 79% of households after the initial visit and for 94% of households after follow-up visits; vaccination coverage rates were similar with and without follow-up. Coverage among children on remote islands differed substantially from that of their counterparts on the main island indicating a programmatic need for locality-specific information; excluding remote islands from the survey would have had little effect on overall estimates due to small populations and divergent results. Conclusion Strategies to reduce sources of survey error should be maximized in public health surveys. The impact of the 3 strategies illustrated here will vary depending on the primary outcomes of interest and local situations. Survey limitations such as potential for error should be well-documented, and the likely direction and magnitude of bias should be considered.

    The purpose of this study was to investigate the prevalence of occupational exposure incidents among undergraduate dental students and the factors associated with it in the educational dental clinics at Pharos University in Alexandria - Egypt, and to measure the commitment with applying infection control policy in the form of compliance with post-exposure management protocol and reporting exposure incidents. An anonymous self-administered questionnaire consisting of thirteen multiple-choice questions was distributed among 350 undergraduate dental students in mid-senior and senior levels during lectures at the end of the second semester of 2011, with a response rate of 90.00%. About 62.00% of the senior students reported that exposures occurred outside the patient's mouth. A high percentage of both the mid-senior and senior students (74.70% and 70.70%, respectively) reported that they were exposed to multiple sources of incidents. The vast majority of studied groups stated that they didn't follow Infection Control Protocol after Incident Exposure. The findings of this study confirm that dental students experience exposure incidents but are not likely to report them, thus it is important that the principles of infection control training and reporting of all exposure incidents continue to be emphasized throughout undergraduate dental education.

  15. Shocking Results on the Adverse Effects of CO2 Exposures

    2012-01-01

    Carbon dioxide (CO2) is released in large quantities from humans while they live and work in spacecraft or work outside the spacecraft during extravehicular activity (EVA). Removal of this anthropogenic pollutant requires major resources, and these resources increase dramatically as the levels of CO2 set to protect human health and performance are reduced. The current Spacecraft Maximum Allowable Concentration of CO2 aboard the ISS is 0.7% or 5.3 mmHg; however, according to Chits (mission action requests), NASA and its international partners have agreed to control CO2 levels to less than 4 mmHg. In the meantime, retrospective investigations attempting to associate crew symptoms with elevated CO2 levels over the life if the International Space Station (ISS) are underway to determine if this level is sufficient to protect against health and performance decrements. Anecdotal reports suggest that crewmembers are not able to perform complex tasks as readily in spaceflight as they were able during ground-based training. While physiological effects of CO2 have been studied for many decades, it is only recently that the effects of CO2 on higher reasoning capabilities have been studied. The initial results are shocking. For example, one study published in the respected journal Environmental Health Perspectives showed obvious adverse effects of CO2 exposures on higher reasoning at 1.9 mmHg. The implications and limitations of this study are paramount in determining future CO2 SMACs for human spaceflight, both aboard the ISS and in exploration-class missions.

    This Month in Astronomical History is a short (~500 word) column on the AAS website that revisits significant astronomical events or the lives of people who have made a large impact on the field. The monthly column began in July 2016 at the request of the Historical Astronomical Division. Examples of topics that have been covered include Comet Shoemaker-Levy’s collision with Jupiter, the discovery of the moons of Mars, the life of Edwin Hubble, Maria Mitchell’s comet discovery, and the launch of Sputnik II. A survey concerning the column is in progress to ensure the column addresses the interests and needs of a broad readership, including historians, educators, research astronomers, and the general public. Eleven questions focus on the style and content of the column, while eight collect simple demographics. The survey has been available on the AAS website since and was mentioned in several AAS newsletters; however, non-members of AAS were also recruited to include respondents from a variety of backgrounds. Preliminary results of the survey are presented and will be used to hone the style and content of the column to serve the widest possible audience.

    We report on the results from the first six months of the Catalina Real-time Transient Survey (CRTS). In order to search for optical transients with timescales of minutes to years, the CRTS analyses data from the Catalina Sky Survey which repeatedly covers twenty six thousand of square degrees on the sky. The CRTS provides a public stream of transients that are bright enough to be followed up using small telescopes. Since the beginning of the survey, all CRTS transients have been made available to astronomers around the world in real-time using HTML tables, RSS feeds and VOEvents. As part of our public outreach program the detections are now also available in KML through Google Sky. The initial discoveries include over 350 unique optical transients rising more than two magnitudes from past measurements. Sixty two of these are classified as supernovae, based on light curves, prior deep imaging and spectroscopic data. Seventy seven are due to cataclysmic variables (only 13 previously known), while an additional...

    Purpose. To evaluate current exposure levels from pediatric MDCT examinations in order to issue recommendations for the routine clinical practice that may be used for establishing future diagnostic reference levels (DRL). Materials and methods. A survey was conducted at hospital sites affiliated with the SFIPP (Societe Francophone d'Imagerie Pediatrique et Prenatale). Tube potential and volume computed tomography dose index (CTDI) vol. values were obtained for three age groups (1, 5 and 10 years) for typical scanning indications of eight anatomical regions. Results. Twenty of 29 sites provided us with a copy of their protocols. All ages groups combined, 97% of protocols used a tension level {<=} 120 kVp. For age groups 1, 5 and 10 years respectively, the 75. percentiles of dose distributions were: 31, 39.5 and 49.5 mGy for the 'head' protocol; 24, 22 and 24 mGy for 'head and neck'; 11, 11, and 11 mGy for 'paranasal sinuses'; 46, 71 and 87 mGy for 'petrous bone'; 3, 3.5 and 5.5 mGy for 'chest'; 2, 3 and 4 mGy for 'low dose lung'; 4, 4.5 and 7 mGy for 'abdomen-pelvis'; 7,11 and 12 mGy for 'bone'. The inter-center discrepancy for doses were still high. Conclusion. This study provided an evaluation of current practices in reference centers for pediatric imaging and allowed readjustment of MDCT dose recommendations. It could help in the development of DRLS for pediatric MDCT. (author)

    Pesticide exposure is a potential risk factor for increased asthma prevalence among children. The authors used National Health and Nutrition Examination Survey (1999-2008) biomarker data to evaluate dialkylphosphate (DAP) urinary concentrations, serum dichlorodiphenyldichloroethylene (DDE), and asthma among school-aged children (Mexican American, Non-Hispanic Black, Non-Hispanic White). Poisson logistic regression included age, sex, nativity, poverty index ratio, tobacco smoke exposure, and body mass index covariates. No association was found between DAP (N=2,777) and asthma outcomes; adverse effect of DDE (N=940) was suggested for Current Wheeze. Subgroup analyses identified positive associations with some asthma outcomes among Non-Hispanic Blacks, whereas inverse associations were identified among Mexican Americans. Results support previous associations observed among children's DDE exposure and wheeze. Characterization of risk factors for pesticide exposure and disease recognition among Mexican Americans is needed.

    The VLA Sky Survey (VLASS) is a 5520 hour project to survey the 33885 square degrees of the sky above Declination -40 degrees from 2-4 GHz at 2.5" angular resolution using the upgraded Karl G. Jansky Very Large Array (VLA). Over the survey duration of 7 years, each area of the sky will be covered in 3 epochs spaced 32 months apart, to a depth of 0.12mJy/beam rms noise per epoch and 0.07mJy/beam for 3 epochs combined. Pilot observations were taken in mid-2016, with the full survey to start in September 2017. The raw data will be available in the NRAO archive immediately with no proprietary period and science data products will be provided to the community in a timely manner. Basic Data Products (BDP) that will be produced by the survey team include: raw and calibrated visibility data, quick-look continuum images, single-epoch images and spectral image cubes, single-epoch basic object catalogs, and cumulative "static sky" images and image cubes and basic object catalogs to the full survey depth. Single-epoch and cumulative images are in intensity and linear polarization (Stokes IQU). In addition to the BDP provided by NRAO and served through the NRAO archive, there are opportunities for Enhanced Data Products and Services that are provided by the community in partnership with the VLASS team.In this presentation we describe the survey design and the Technical Implementation Plan (TIP) for the VLASS, and report on results from the VLASS Pilot observations. The pilot survey covered 2480 unique square degrees, with 2160 square degrees within the SDSS/FIRST footprint. The pilot also covered key deep fields including COSMOS, GOODS-N, CDFS, Elais-N1, and the SDSS Stripe-82. Preliminary imaging and comparisons have been carried out for selected pilot fields as part of early science verification. We also discuss the technical issues and challenges remaining to be addressed before commencing the survey and our plans moving forward. There are also opportunities for community

    Since the numbers of women pursuing technical careers in aviation continues to remain very low, a study on retention of women was undertaken by a team of university faculty from Embry Riddle Aeronautical University, Arizona State University, and Kent State University. The study was initiated to discover the factors that influence women once they have already selected an aviation career and to ascertain what could be done to support those women who have demonstrated a serious interest in an aviation career by enrolling in a collegiate aviation program. This paper reports preliminary results of data collected in the first and second years of the study. The data was collected from surveys of 390 college students (195 women and 195 men) majoring in aviation programs in nine colleges and universities, representing widely varied geographic areas and including both two- and four-year institutions. Results revealed significant areas of concern among women in pilot training. When queried about these concerns, differences were evident in the responses of the male and female groups. These differences were expected. However, a surprising finding was that women in early stages of pilot training responded differently from women in more experienced stages, These response differences did not occur among the men surveyed. The results, therefore, suggest that women in experienced stages of training may have gone through an adaptation process and reflect more male-like attitudes about a number of objects, including social issues, confidence, family, and career.

    As part of an array of strategies to combat climate change, biomass is being used increasingly as a substitute for fossil fuels. It is important that the sustainability benefits thus accruing to the Netherlands are not at the expense of sustainable development in producer countries. Against this background the 'Sustainable biomass imports' project group is developing a set of criteria for evaluating the sustainability of biomass projects. To assess support for such criteria, CE conducted an internet survey among the various stakeholders (NGOs, industry, government), drawing a total of 104 responses. This report presents all the results and conclusions of the survey, for each category of stakeholders and overall. Among the most striking conclusions are the following: The majority of respondents see a sustainability audit on biomass as feasible, provided the sustainability criteria are adequate for the purpose (68%); Almost all the respondents are of the opinion that such sustainability criteria should apply to all applications of biomass (90%); On the issue of whether these criteria should vary according to the producer region concerned, respondents were divided (50% for, 50% against); Many NGOs state there should be different sustainability criteria in force for different biomass flows (50%), in contrast to industry, which argues for a uniform set of criteria for all flows; Most respondents hold that any biomass criteria should apply to both subsidised and unsubsidised projects; At the same time, a sizable majority of respondents state that subsidisation of biomass projects should depend on the degree of sustainability (72%) and in particular on the CO2 emission cuts achieved, this being regarded as the single most important factor; When it comes to the issue of GMO, opinions differ markedly between NGOs and industry, with some 75% of NGOs wanting this aspect included, but only 10% of industry; Respondents also commented on a number of additional issues

    Full Text Available Introduction: The therapeutic benefits of yoga and meditation are well documented, yet little is known about the practice of yoga in Australia or elsewhere, whether as a physical activity, a form of therapy, a spiritual path or a lifestyle. Materials and Methods: To investigate the practice of yoga in Australia, a national survey of yoga practitioners was conducted utilizing a comprehensive web-based questionnaire. Respondents were self-selecting to participate. A total of 3,892 respondents completed the survey. Sixty overseas respondents and 1265 yoga teachers (to be reported separately were excluded, leaving 2,567 yoga practitioner respondents. Results: The typical yoga survey respondent was a 41-year-old, tertiary educated, employed, health-conscious female (85% women. Asana (postures and vinyasa (sequences of postures represented 61% of the time spent practicing, with the other 39% devoted to the gentler practices of relaxation, pranayama (breathing techniques, meditation and instruction. Respondents commonly started practicing yoga for health and fitness but often continued practicing for stress management. One in five respondents practiced yoga for a specific health or medical reason which was seen to be improved by yoga practice. Of these, more people used yoga for stress management and anxiety than back, neck or shoulder problems, suggesting that mental health may be the primary health-related motivation for practicing yoga. Healthy lifestyle choices were seen to be more prevalent in respondents with more years of practice. Yoga-related injuries occurring under supervision in the previous 12 months were low at 2.4% of respondents. Conclusions: Yoga practice was seen to assist in the management of specific health issues and medical conditions. Regular yoga practice may also exert a healthy lifestyle effect including vegetarianism, non-smoking, reduced alcohol consumption, increased exercise and reduced stress with resulting cost benefits

    2013-12-01

    To assess knowledge on the abdominal wall closure through a surgeon cohort survey. A twenty question individual questionnaire on laparotomy in elective surgery. A total of 131 surgeons from seven hospitals responded (72% specialists and 28% in training). 71% of respondents estimated the frequency of incisional hernia to be higher than 15% and 54% considered the technique to be the most significant risk factor. 85% considered midline laparotomy closed with slow absorbable suture (57%) in a single layer (66%) to be the most appropriate technique. 67% believed retention sutures to be the appropriate prevention technique. 50% did not know or could not apply the 4:1 technique. 87% considered that an incisional hernia can be prevented and that the technique is the most important factor on which to act. 84% believed that a prosthesis can prevent the occurrence of incisional hernia, whereas 40% of respondents never use it and only 38% use it in patients at risk. On comparing surveys between specialists and residents, significant differences appeared in terms of a better understanding of the theoretical technical aspects in trainee surgeons. Although the results show an adequate understanding of the epidemiology and risk factors for development of incisional hernia, training and consensus measures are likely to be introduced in some basic technical aspects in order to improve results in laparotomy closure.

    2015-01-01

    This study aims to describe current risk management practices and policies across the world in relation to personal exposures from devices emitting radiofrequency fields, environmental exposures from fixed installations and exposures in the work environment. Data from 86 countries representing all WHO regions were collected through a survey. The majority of countries (76.8 %) had set exposure limits for mobile devices, almost all (90.7 %) had set public exposure limits for fixed installations and 76.5 % had specified exposure limits for personnel in occupational settings. A number of other policies had been implemented at the national level, ranging from information provisions on how to reduce personal exposures and restrictions of usage for certain populations, such as children or pregnant women to prevention of access around base stations. This study suggests that countries with higher mobile subscriptions tend to have set radiofrequency exposure limits for mobile devices and to have provisions on exposure measurements about fixed installations.

    This study's objective was to assess the patient safety culture in a large, integrated health delivery system's pharmacy department to allow for benchmarking with other health systems. This was a cross-sectional survey conducted in a pharmacy department consisting of staff members who provide dispensing, clinical, and support services within an integrated health delivery system. The U.S. Agency for Healthcare Research and Quality's 11-composite, validated Pharmacy Survey on Patient Safety Culture questionnaire was transcribed into an online format. All departmental staff members were invited to participate in this anonymous survey. Cronbach α and overall results and contrasts between dispensing and clinical services staff and dispensing pharmacists and technicians/clerks as percentage positive scores (PPSs) are presented. Differences in contrasts were assessed with χ tests of association. Completed questionnaires were received from 598 (69.9%) of 855 employees. Cronbach α ranged from 0.55 to 0.90. Overall, the highest and lowest composite PPSs were for patient counseling (94.5%) and staffing and work pressure (44.7%), respectively. Compared with dispensing service, the clinical service participants had statistically higher PPSs for all composites except patient counseling, communication about mistakes, and staffing and work pressure (all P > 0.05). The technicians/clerks had a statistically higher PPS compared with the pharmacists for communication about mistakes (P = 0.007). All other composites were equivalent between groups. Patient counseling consistently had the highest PPS among composites measured, but opportunities existed for improvement in all aspects measured. Future research should identify and assess interventions targeted to improving the patient safety culture in pharmacy.

    2014-01-01

    Objective: Our paper presents findings from the first population survey of stigma in Canada using a new measure of stigma. Empirical objectives are to provide a descriptive profile of Canadian’s expectations that people will devalue and discriminate against someone with depression, and to explore the relation between experiences of being stigmatized in the year prior to the survey among people having been treated for a mental illness with a selected number of sociodemographic and mental health–related variables. Method: Data were collected by Statistics Canada using a rapid response format on a representative sample of Canadians (n = 10 389) during May and June of 2010. Public expectations of stigma and personal experiences of stigma in the subgroup receiving treatment for a mental illness were measured. Results: Over one-half of the sample endorsed 1 or more of the devaluation discrimination items, indicating that they believed Canadians would stigmatize someone with depression. The item most frequently endorsed concerned employers not considering an application from someone who has had depression. Over one-third of people who had received treatment in the year prior to the survey reported discrimination in 1 or more life domains. Experiences of discrimination were strongly associated with perceptions that Canadians would devalue someone with depression, younger age (12 to 15 years), and self-reported poor general mental health. Conclusions: The Mental Health Experiences Module reflects an important partnership between 2 national organizations that will help Canada fulfill its monitoring obligations under the United Nations Convention on the Rights of Persons with Disabilities and provide a legacy to researchers and policy-makers who are interested in monitoring changes in stigma over time.

  18. Surveillance indicators for potential reduced exposure products (PREPs: developing survey items to measure awareness

    Directory of Open Access Journals (Sweden)

    2009-10-01

    Full Text Available Abstract Background Over the past decade, tobacco companies have introduced cigarettes and smokeless tobacco products (known as Potential Reduced Exposure Products, PREPs with purportedly lower levels of some toxins than conventional cigarettes and smokeless products. It is essential that public health agencies monitor awareness, interest, use, and perceptions of these products so that their impact on population health can be detected at the earliest stages. Methods This paper reviews and critiques existing strategies for measuring awareness of PREPs from 16 published and unpublished studies. From these measures, we developed new surveillance items and subjected them to two rounds of cognitive testing, a common and accepted method for evaluating questionnaire wording. Results Our review suggests that high levels of awareness of PREPs reported in some studies are likely to be inaccurate. Two likely sources of inaccuracy in awareness measures were identified: 1 the tendency of respondents to misclassify "no additive" and "natural" cigarettes as PREPs and 2 the tendency of respondents to mistakenly report awareness as a result of confusion between PREPs brands and similarly named familiar products, for example, Eclipse chewing gum and Accord automobiles. Conclusion After evaluating new measures with cognitive interviews, we conclude that as of winter 2006, awareness of reduced exposure products among U.S. smokers was likely to be between 1% and 8%, with the higher estimates for some products occurring in test markets. Recommended measurement strategies for future surveys are presented.

    Nainital;Cape Survey was started with an aim to search for new rapidly oscillating Ap stars in the northern hemisphere.We discovered one new mono-periodic roAp star HD 12098. The frequency separation of HD 12098 suggests a rotation period of 5.5 days for the star. We summarize here the observations of HD 12098 and briefly discuss the results of the multi-site observation campaign organized to resolve the ambiguity in the determination of the rotation period of HD 12098. Other interesting results like non-oscillating Ap stars discovered and two candidate stars in which roAp periodicity is seen but not confirmed are also discussed.

    The Taiwanese-American Occultation Survey (TAOS) aims to detect serendipitous occultations of stars by small ({approx}1 km diameter) objects in the Kuiper Belt and beyond. Such events are very rare (<10{sup -3} events per star per year) and short in duration ({approx}200 ms), so many stars must be monitored at a high readout cadence. TAOS monitors typically {approx}500 stars simultaneously at a 5 Hz readout cadence with four telescopes located at Lulin Observatory in central Taiwan. In this paper, we report the results of the search for small Kuiper Belt objects (KBOs) in seven years of data. No occultation events were found, resulting in a 95% c.l. upper limit on the slope of the faint end of the KBO size distribution of q = 3.34-3.82, depending on the surface density at the break in the size distribution at a diameter of about 90 km.

    In the present study, malignant mesothelioma (MM) cases in Japan were investigated retrospectively. We extracted records for 6030 cases of death due to MM between 2003 and 2008 to clarify the clinical features of MM, including its association with asbestos exposure (AE). Of all these cases, a clinical diagnosis of MM was confirmed for 929. The origin of MM included the pleura in 794 cases (85.5%), the peritoneum in 123 cases (13.2%), the pericardium in seven cases (0.8%), and the testicular tunica vaginalis in five cases (0.5%). The histological subtypes of MM included 396 epithelioid (55.9%), 154 sarcomatoid (21.7%), 126 biphasic (17.8%), and 33 cases (4.7%) classified as "other types". Of all the MM cases, AE was indicated in 76.8% and pleural plaques were detected in 34.2%. The number of asbestos particles was determined in 103 cases of MM. More than 1000 asbestos particles per gram dried lung tissue were detected in 74.8% of cases and more than 5000 particles were detected in 43.7% of cases. We compared patient characteristics and the diagnostic procedures for MM before and after the "Kubota shock". Compared with the early phase of this study (2003-2005), the median age at diagnosis of MM was higher, the number of cases without definite diagnosis of MM was lower, the proportion of cases diagnosed by thoracoscopy was higher, and the percentage of cases in which the occupational history was described in the medical records was significantly higher in the later phase (2006-2008). Our study confirmed that more than 70% of MM cases in Japan are associated with AE. The "Kubota shock" may affect some features pertaining to MM.

    STARtorialist (startorialist.com) is a Tumblr-based blog that curates the proliferation of "Astro Fashion" - clothing accessories, decor, and more - with the goal of celebrating the beauty of the universe and highlighting the science behind the astronomical imagery. Since launching in January 2013, we have written over 1000 unique posts about everything from handmade and boutique products to mass-produced commercial items to haute couture seen on fashion runways. Each blog post features images and descriptions of the products with links to the original astronomical images or other relevant science content. We also feature profiles of astronomers, scientists, students, and communicators wearing, making, or decorating with "startorial" items. Our most popular posts accumulate hundreds or thousands of notes (faves or reblogs, in Tumblr parlance), and one post has nearly 150,000 notes. In our second year, we have grown from 1,000 to just shy of 20,000 followers on Tumblr, with an increased audience on Twitter, Instagram, and Facebook as well. We present preliminary results from a reader survey conducted September-October 2015 in collaboration with science communication researcher Dr. Paige Jarreau. The survey provides data on reader habits, motivations, attitudes, and demographics in order to assess how STARtorialist has influenced our readers' views on science, scientists, and the scientific community as a whole.

  3. Salvia divinorum use and phenomenology: results from an online survey.

    Salvia divinorum is a hallucinogenic plant with ethnopharmacological and recreational uses. It differs from classic serotonergic hallucinogens such as LSD and psilocin in both phenomenology and potent agonist activity of the active component salvinorin A at κ-opioid receptors. Awareness of S. divinorum has grown recently, with both an increase in its public representation and concern over its potential harmful effects. This discussion is particularly relevant as S. divinorum is legal to use in many countries and regions and easily available through online retailers. Drawing upon previous investigations of S. divinorum and other hallucinogens, this study surveyed 154 recent users and questioned them on their use behaviours, consequences of use and other attitudinal measures. Although reporting an extensive substance use history, and considering the limitations of online surveys, there was little evidence of dysfunctional S. divinorum use, and few reports of troubling adverse consequences of use. Furthermore, there was no evidence that users exhibited increased schizotypy. Respondents reported that S. divinorum produced mixed hallucinogenic and dissociative effects, which lends support to assertions that it phenomenologically differs from other hallucinogens with primary serotonergic activity. The functions of use changed with greater experiences with the drug, and although many respondents reported use of S. divinorum as an alternative to illegal drugs it, was apparent that legal proscription would be unlikely to dissuade them from use. These results are discussed with reference to psychopharmacologically informed public health responses to substance use.

    Full Text Available Purpose: identify by means of a survey the off-label treatments more often used in the oncohaematology area, as well as to know the established procedures and criteria used to authorise those treatments. Methods: a four-section survey was designed: 1 demographic data and hospital activity, 2 Off-label treatments protocol, 3 Approval criteria and 4 Off-label oncology treatments conducted during the last year. Results: in 42.1% of the hospitals it’s needed an authorisation before dispensing in more tan 80% of the treatments. The most influential factor in the approval-dispensation system is the available evidence. The consent of the hospital management with previous Pharmacy department’s report was the most common authorisation procedure. 55.3% of the hospitals settled specific patient criteria to help the decision-making altogether with the available safety and efficacy data of the drug for the requested indication. In most centers a lower level of evidence is accepted if there are no therapeutic alternatives as well as in tumors of low prevalence. Most of the centers have not clearly established a criterion of effectiveness to consider a benefit as clinically relevant, nor the cost-effectiveness threshold for approving a FFT. Conclusions: there is a great variability in the off-label treatments use and also in the criteria used for its approval.

    The Danish Emergency Management Agency (DEMA) in co-operation with the Technical University of Denmark (TUD), Department of Automation, participated in the international exercise RESUME-95 arranged in Finland in August 1995. DEMA performed measurement with their airborne gamma-ray surveying system. Surveys were done in the three areas known as AREA I, II, III. Results from AREA II (3 km x 6 km) show that the apparent {sup 137}Cs deposition assuming a deposition profile equal to the profile in AREA I based on soil samples varies from a few 10th kBqm{sup -2} up to 110 kBqm{sup -2}. However, a detailed analysis using a new method, Noise Adjusted Singular Value Decomposition (NASVD), shows that the true variations probably are smaller and that the observed differences to some extend are due to major variations in the depth distribution of the cesium. For example agricultural areas appears to have cesium much deeper deposit than the undisturbed areas. Another interesting result is that the NASVD analysis shows that the ration of {sup 134}Cs to {sup 137}Cs is fixed and approximately 0.03 (August 1995) a number in good agreement with the expected ratio from the Chernobyl accident. No true real-time software for source detection is yet integrated in the Danish system. Results from AREA III, however, show that the implemented software for rapid post processing of data worked excellent for detection of radioactive sources. Post analysis using NASVD demonstrates that all sources except for a small {sup 137}Cs source can be localized. (au).

    Bone scintigraphy is used for displaying the radiologic undiagnosed bone lesions in nuclear medicine. It's general indications are researching bone metastases, detection of radiographically occult fractures, staging and follow-up in primary bone tumors, diagnosis of paget's disease, investigation of loosening and infection in orthopedic implants. It is applied with using 99mTc labeled radiopharmaceuticals (e.g 99m Tc MDP,99mTc HEDP and 99mTc HMDP). 20 -25 mCi IV radiotracer was injected into vein and radiotracer emits gamma radiation. Patient waits in isolated room for about 3 hours then a gamma camera scans radiation area and creates an image. When some patient's situation is not good, patients are hospitalized until the scanning because of patients' close contact care need. In this study, measurements were taken from ten patients using Geiger Muller counter. After these measurements, we calculated nurse's exposure radiations from patient's routine treatment, examination and emergency station.

    Objective Assess the national prevalence of current workplace exposure to potential skin hazards, secondhand smoke (SHS), and outdoor work among various industry and occupation groups. Also, assess the national prevalence of chronic workplace exposure to vapors, gas, dust, and fumes (VGDF) among these groups. Methods Data were obtained from the 2010 National Health Interview Survey (NHIS). NHIS is a multistage probability sample survey of the civilian non-institutionalized population of the US. Prevalence rates and their variances were calculated using SUDAAN to account for the complex NHIS sample design. Results The data for 2010 were available for 17,524 adults who worked in the 12 months that preceded interview. The highest prevalence rates of hazardous workplace exposures were typically in agriculture, mining, and construction. The prevalence rate of frequent handling of or skin contact with chemicals, and of non-smokers frequently exposed to SHS at work was highest in mining and construction. Outdoor work was most common in agriculture (85%), construction (73%), and mining (65%). Finally, frequent occupational exposure to VGDF was most common among mining (67%), agriculture (53%), and construction workers (51%). Conclusion We identified industries and occupations with the highest prevalence of potentially hazardous workplace exposures, and provided targets for investigation and intervention activities.

    Estimates suggest that up to 90% or more youth between 12 and 18 years have access to the Internet. Concern has been raised that this increased accessibility may lead to a rise in pornography seeking among children and adolescents, with potentially serious ramifications for child and adolescent sexual development. Using data from the Youth Internet Safety Survey, a nationally representative, cross-sectional telephone survey of 1501 children and adolescents (ages 10-17 years), characteristics associated with self-reported pornography seeking behavior, both on the Internet and using traditional methods (e.g., magazines), are identified. Seekers of pornography, both online and offline, are significantly more likely to be male, with only 5% of self-identified seekers being female. The vast majority (87%) of youth who report looking for sexual images online are 14 years of age or older, when it is developmentally appropriate to be sexually curious. Children under the age of 14 who have intentionally looked at pornography are more likely to report traditional exposures, such as magazines or movies. Concerns about a large group of young children exposing themselves to pornography on the Internet may be overstated. Those who report intentional exposure to pornography, irrespective of source, are significantly more likely to cross-sectionally report delinquent behavior and substance use in the previous year. Further, online seekers versus offline seekers are more likely to report clinical features associated with depression and lower levels of emotional bonding with their caregiver. Results of the current investigation raise important questions for further inquiry. Findings from these cross-sectional data provide justification for longitudinal studies aimed at parsing out temporal sequencing of psychosocial experiences.

    Background: Limited epidemiologic data are available concerning the cardiovascular effects of cadmium exposure, although recent studies suggest associations with myocardial infarction and peripheral arterial disease. We examined the associations of cadmium exposure with cardiovascular disease in nationally representative general Korean adults. Methods: We used cross-sectional data on blood cadmium and self-reported diagnoses of ischemic heart disease (IHD), stroke, and hypertension in a sub-sample of 1908 adults, aged 20 years and older, who participated in the 2005 Korea National Health and Nutrition Examination Survey (KNHANES). We used survey logistic regression models accounting for the complex sampling design to estimate the odds ratios (OR), adjusting for age, education, income, alcohol, smoking, body mass index, waist circumference, family history of hypertension, blood pressure, and blood lead. Results: The geometric mean of blood cadmium was 1.53 {mu}g/L. After adjusting for potential confounders, an interquartile range (IQR) increase in blood cadmium (0.91 {mu}g/L) was found to be associated with an increased risk for IHD (OR 2.1, 95% confidence interval (CI) 1.3-3.4). An IQR increase in blood cadmium was found to be associated with an elevated risk for hypertension only among men (OR 1.4, 95% CI 1.1-1.8) but not among women. No association was observed with stroke in both genders. Conclusions: These findings suggest that cadmium in blood may be associated with an increased risk for IHD and hypertension in the general Korean adult population.

    Full Text Available Pre-testing and post-testing is a commonly used method in Physics Education Research to assess student learning gains. It is well recognized in the community that timings and incentives in delivering conceptual tests can impact test results. However, it is difficult to control these variables across different studies. As a common practice, a pre-test is often administered either at or near the beginning of a course, while a post-test can be given either at or near the end of a course. Also, in conducting such tests there often is no norm as to whether incentives should be offered to students. Because these variations can significantly affect test results, it is important to study and document their impact. We analyzed five years of data that were collected at The Ohio State University from over 2100 students, who took both the pre-test and post-test of the Conceptual Survey of Electricity and Magnetism under various timings and incentives. We observed that the actual time frame for giving a test has a marked effect on the test results and that incentive granting also has a significant influence on test outcomes. These results suggest that one should carefully monitor and document the conditions under which tests are administered.

    SETH i is a survey of the distribution of galactic neutral hydrogen being performed comensally at the NAIC Arecibo Observatory. At the same time that observers use receivers in the Gregorian dome, SETHi is recording a 2.5MHz band centered at 1420 MHz from a flat feed on Carriage House 1. During normal astronomical observations, the SETH i feed scans across the sky at twice the sidereal rate. During 4 years of observations, we have accumulated over 15,000 hours of data covering most of the sky accessible to Arecibo. This survey has higher angular resolution than existing single dish surveys and higher sensitivity than existing or planned interferometric surveys.

    To evaluate whether women engage in outdoor activities and high altitude travel during pregnancy; the health care advice received regarding high altitude during pregnancy; and the association between high altitude exposure and self-reported pregnancy complications. An online survey of women with at least 1 pregnancy distributed on websites and e-mail lists targeting mothers and/or mountain activities. Outcome measures were outdoor activities during pregnancy, high altitude (>2440 m) exposure during pregnancy, and pregnancy and perinatal complications. Hiking, running, and swimming were the most common activities performed during pregnancy. Women traveled to high altitude in over half of the pregnancies (244/459), and most did not receive counseling regarding altitude (355, 77%), although a small proportion (14, 3%) were told not to go above 2440 m. Rates of miscarriage and most other complications were similar between pregnancies with and without travel above 2440 m. Pregnancies with high altitude exposure were more likely to have preterm labor (odds ratio [OR] 2.3; 95% CI 0.97-5.4; P = .05). Babies born to women who went to high altitude during pregnancy were more likely to need oxygen at birth (OR 2.34; 95% CI 1.04-5.26; P < .05) but had similar rates of neonatal intensive care unit admission (P = not significant). Our results suggest pregnant women who are active in outdoor sports and travel to high altitude have a low rate of complications. Given the limitations of our data, further research is necessary on the risks associated with high altitude travel and physical activity and how these apply to the general population.

    Context. Debris discs are a consequence of the planet formation process and constitute the fingerprints of planetesimal systems. Their solar system counterparts are the asteroid and Edgeworth-Kuiper belts.Aims. The DUNES survey aims at detecting extra-solar analogues to the Edgeworth-Kuiper belt around solar-type stars, putting in this way the solar system into context. The survey allows us to address some questions related to the prevalence and properties of planetesimal systems.Methods. We used Herschel PACS to observe a sample of nearby FGK stars. Data at 100 and 160 micron were obtained, complemented in some cases with observations at 70 micron, and at 250, 350 and 500 micron using SPIRE. The observing strategy was to integrate as deep as possible at 100 micron to detect the stellar photosphere. Results. Debris discs have been detected at a fractional luminosity level down to several times that of the Edgeworth-Kuiper belt. The incidence rate of discs around the DUNES stars is increased from a rate of approx. 12.1% +/- 5% before Herschel to approx 20.2 % +/- % 2. A significant fraction (approx. 52%) of the discs are resolved, which represents an enormous step ahead from the previously known resolved discs. Some stars are associated with faint far-IR excesses attributed to a new class of cold discs. Although it cannot be excluded that these excesses are produced by coincidental alignment of background galaxies, statistical arguments suggest that at least some of them are true debris discs. Some discs display peculiar SEDs with spectral indexes in the 70-160 micron range steeper than the Rayleigh-Jeans one. An analysis of the debris disc parameters suggests that a decrease might exist of the mean black body radius from the F-type to the K-type stars. In addition, a weak trend is suggested for a correlation of disc sizes and an anticorrelation of disc temperatures with the stellar age.

    Full Text Available Objectives: Expanding the information on exposure to environmental tobacco smoke (ETS at home and its associates is of great public health importance. The aim of the current analysis was to evaluate associates of exposure to environmental tobacco smoke among economically active male and female adults in Poland in their place of residence. Material and Methods: Data on the representative sample of 7840 adults from the Global Adult Tobacco Survey (GATS carried out in Poland in the years 2009 and 2010 were applied. The Global Adult Tobacco Survey is a nationally representative household study. The logistic regression model was used for relevant calculations. Results: The exposure to environmental tobacco smoke in the place of living affected 59% of studied subjects. Out of non-smokers 42% of males and 46% females were exposed to the ETS in the at home. Increased risk of residential ETS exposure was associated with low education attainment, lack of awareness on adverse health consequences of second hand smoke (SHS, low level of support for tobacco control policies, living with a smoker. One of the factors associated with the ETS exposure was also the approval for smoking at home of both genders. The residential ETS exposure risk was the highest among males (odds ratio (OR = 7.1, 95% confidence interval (CI: 6.1–13.8, p < 0.001 and females (OR = 8.1, 95% CI 6.5–11.8, p < 0.001 who declared that smoking was allowed in their place of residence compared to respondents who implemented smoking bans at their place of residence. Conclusions: Campaigns to decrease social acceptance of smoking and encourage adopting voluntary smoke-free rules at home might decrease the ETS exposure and reduce related risks to the health of the Polish population. Educational interventions to warn about adverse health effects of the ETS should be broadly implemented particularly in high risk subpopulations.

  3. Mimicking natural systems: Changes in behavior as a result of dynamic exposure to naproxen.

    Animals living in aquatic habitats regularly encounter anthropogenic chemical pollution. Typically, the toxicity of a chemical toxicant is determined by the median lethal concentration (LC50) through a static exposure test. However, LC50 values and static tests do not provide an accurate representation of exposure to pollutants within natural stream systems. In their native habitats, animals experience exposure as a fluctuating concentration due to turbulent mixing, temporal variations of contamination (seasonal inputs), and contaminant input type (point vs. non-point). Research has shown that turbulent environments produce exposures with a high degree of fluctuation in frequency, duration, and intensity. In order to more effectively evaluate the effects of pollutants, we created a dynamic exposure paradigm, utilizing both flow and substrate within a small mesocosm. A commonly used pharmaceutical, naproxen, was used as the toxicant and female crayfish (Orconectes virilis) as the target organism to investigate changes in fighting behavior as a result of dynamic exposure. Crayfish underwent either a 23h long static or a dynamic exposure to naproxen. Following exposure, the target crayfish and an unexposed size matched opponent underwent a 15min fight trial. These fight trials were recorded and later analyzed using a standard ethogram. Results indicate that exposure to sublethal concentrations of naproxen, in both static and flowing conditions, negatively impact aggressive behavior. Results also indicate that a dynamic exposure paradigm has a greater negative impact on behavior than a static exposure. Turbulence and habitat structure play important roles in shaping chemical exposure. Future research should incorporate features of dynamic chemical exposure in order to form a more comprehensive image of chemical exposure and predict the resulting sublethal effects from exposure. Possible techniques for assessment include utilizing flow-through experimental set-ups in

    Disruptive intraoperative behavior has detrimental effects to clinicians, institutions, and patients. How clinicians respond to this behavior can either exacerbate or attenuate its effects. Previous investigations of disruptive behavior have used survey scales with significant limitations. The study objective was to develop appropriate scales to measure exposure and responses to disruptive behavior. We obtained ethics approval. The scales were developed in a sequence of steps. They were pretested using expert reviews, computational linguistic analysis, and cognitive interviews. The scales were then piloted on Canadian operating room clinicians. Factor analysis was applied to half of the data set for question reduction and grouping. Item response analysis and theoretical reviews ensured that important questions were not eliminated. Internal consistency was evaluated using Cronbach α. Model fit was examined on the second half of the data set using confirmatory factor analysis. Content validity of the final scales was re-evaluated. Consistency between observed relationships and theoretical predictions was assessed. Temporal stability was evaluated on a subsample of 38 respondents. A total of 1433 and 746 clinicians completed the exposure and response scales, respectively. Content validity indices were excellent (exposure = 0.96, responses = 1.0). Internal consistency was good (exposure = 0.93, responses = 0.87). Correlations between the exposure scale and secondary measures were consistent with expectations based on theory. Temporal stability was acceptable (exposure = 0.77, responses = 0.73). We have developed scales measuring exposure and responses to disruptive behavior. They generate valid and reliable scores when surveying operating room clinicians, and they overcome the limitations of previous tools. These survey scales are freely available.

    Engineering, administrative, and work practice controls have been recommended for many years to minimize exposure to nitrous oxide during dental procedures. To better understand the extent to which these exposure controls are used, the NIOSH Health and Safety Practices Survey of Healthcare Workers was conducted among members of professional practice organizations representing dentists, dental hygienists and dental assistants. The anonymous, modular, web-based survey was completed by 284 dental professionals in private practice who administered nitrous oxide to adult and/or pediatric patients in the seven days prior to the survey. Use of primary engineering controls [i.e., nasal scavenging mask and/or local exhaust ventilation (LEV) near the patient's mouth] was nearly universal, reported by 93% and 96% of respondents who administered to adult (A) and pediatric (P) patients, respectively. However, adherence to other recommended precautionary practices were lacking to varying degrees, and were essentially no different among those administering nitrous oxide to adult or pediatric patients. Examples of work practices which increase exposure risk, expressed as percent of respondents, included: not checking nitrous oxide equipment for leaks (41% A; 48% P); starting nitrous oxide gas flow before delivery mask or airway mask was applied to patient (13% A; 12% P); and not turning off nitrous oxide gas flow before turning off oxygen flow to the patient (8% A; 7% P). Absence of standard procedures to minimize worker exposure to nitrous oxide (13% of all respondents) and not being trained on safe handling and administration of nitrous oxide (3%) were examples of breaches of administrative controls which may also increase exposure risk. Successful management of nitrous oxide emissions should include properly fitted nasal scavenging masks, supplemental LEV (when nitrous oxide levels cannot be adequately controlled using nasal masks alone), adequate general ventilation, regular

    Exposure to contaminants in fish may be associated with adverse health outcomes even as fish consumption is generally considered beneficial. Risk assessments conducted to support regulatory analyses rely on quantitative fish consumption estimates. Here we report the results of a national survey of high-frequency fish consumers (n = 2099) based on a survey population statistically representative of ~17.6 million U.S. individuals consuming three or more fish meals per week. The survey was conducted during 2013 using an on-line survey instrument. Total fish consumption averaged 111g/day from market, restaurant and self-caught sources. Depending on the season, the incidence of individuals reporting consumption of self-caught species ranged between 10-12% of our high-frequency fish consuming demographic, averaging approximately 30g/day and comprising 23% of total fish consumption from all sources of fish. Recreational or self-caught consumption rates vary regionally and are poorly understood, particularly for high-frequency consumers, making it difficult to support national-scale assessments. A divergence between sport-fishing and harvesting of fish as a food-staple is apparent in survey results given differences in consumption patterns with income and education. Highest consumption rates were reported for low income respondents more likely to harvest fish as a food staple. By contrast, the incidence of self-caught fish consumption was higher with income and education although overall consumption rates were lower. Regional differences were evident, with respondents from the East-South Central and New England regions reporting lowest consumption rates from self-caught fish on the order of 12-16g/day and those from Mountain, Pacific and Mid-Atlantic regions reporting highest rates ranging from 44 to 59g/day. Respondent-specific consumption rates together with national-level data on fish tissue concentrations of PCBs, MeHg, and PFOS suggest that 10-58% of respondents

    During the late 1950s and early 1960s, the former Dow Chemical Company plant, now owned and operated by Spectrulite Consortium Inc., supplied materials and provided services for the Atomic Energy Commission (AEC) under purchase orders issued by the Mallinckrodt Chemical Company, a primary AEC contractor. Information indicates that research and development work involving gamma-phase extrusion of uranium metal was conducted at the Dow Chemical plant. Because documentation establishing the current radiological condition of the property was unavailable, a radiological survey was conducted by members of the Measurement Applications and Development Group of the Oak Ridge National Laboratory in March 1989. The survey included: measurement of indoor gamma exposure rates; collection and radionuclide analysis of dust and debris samples; and measurements to determine alpha and beta-gamma surface contamination. The results of the survey demonstrate that Building 6, the area uranium extrusion and rod-straightening work occurred, is generally free of radioactive residuals originating from former DOE-sponsored activities. However, {sup 238}U- and {sup 232}Th-contaminated dust was found on overhead beams at the south end of Building 6. These findings suggest that past DOE-supported operations were responsible for uranium-contaminated beam dust in excess of guidelines in Building 6. However, the contamination is localized and limited in extent, rendering it highly unlikely that under present use an individual working in or frequenting these remote areas would receive a significant radiation exposure. We recommend that additional scoping survey measurements and sampling be performed to further define the extent of indoor uranium contamination southward to include Building 4 and northward throughout Building 6. 5 refs., 11 figs., 4 tabs.

    Context. We present the results of a seven-year-long radial velocity survey of a sample of 88 main-sequence and evolved stars to reveal signatures of Jupiter-mass planets in the solar-age and solar-metallicity open cluster M 67. Aims: We aim at studying the frequency of giant planets in this cluster with respect to the field stars. In addition, our sample is also ideal to perform a long-term study to compare the chemical composition of stars with and without giant planets in detail. Methods: We analyzed precise radial velocity (RV) measurements obtained with the HARPS spectrograph at the European Southern Observatory (La Silla), the SOPHIE spectrograph at the Observatoire de Haute-Provence (France), the HRS spectrograph at the Hobby Eberly Telescope (Texas), and the HARPS-N spectrograph at the Telescopio Nazionale Galileo (La Palma). Additional RV data come from the CORALIE spectrograph at the Euler Swiss Telescope (La Silla). We conducted Monte Carlo simulations to estimate the occurrence rate of giant planets in our radial velocity survey. We considered orbital periods between 1.0 day and 1000 days and planet masses between 0.2 MJ and 10.0 MJ. We used a measure of the observational detection efficiency to determine the frequency of planets for each star. Results: All the planets previously announced in this RV campaign with their properties are summarized here: 3 hot Jupiters around the main-sequence stars YBP1194, YBP1514, and YBP401, and 1 giant planet around the evolved star S364. Two additional planet candidates around the stars YBP778 and S978 are also analyzed in the present work. We discuss stars that exhibit large RV variability or trends individually. For 2 additional stars, long-term trends are compatible with new binary candidates or substellar objects, which increases the total number of binary candidates detected in our campaign to 14. Based on the Doppler-detected planets discovered in this survey, we find an occurrence of giant planets of 18

    We present the Multifrequency Snapshot Sky Survey (MSSS), the first northern-sky LOFAR imaging survey. In this introductory paper, we first describe in detail the motivation and design of the survey. Compared to previous radio surveys, MSSS is exceptional due to its intrinsic multifrequency nature providing information about the spectral properties of the detected sources over more than two octaves (from 30 to 160 MHz). The broadband frequency coverage, together with the fast survey speed generated by LOFAR's multibeaming capabilities, make MSSS the first survey of the sort anticipated to be carried out with the forthcoming Square Kilometre Array (SKA). Two of the sixteen frequency bands included in the survey were chosen to exactly overlap the frequency coverage of large-area Very Large Array (VLA) and Giant Metrewave Radio Telescope (GMRT) surveys at 74 MHz and 151 MHz respectively. The survey performance is illustrated within the "MSSS Verification Field" (MVF), a region of 100 square degrees centered at J...

    To determine the survey-related experiential and attitudinal correlates of future health-related survey participation. From July 21, 2005, through October 25, 2005, we conducted a mixed-mode mail and telephone survey of 1636 noninstitutionalized Minnesota residents aged 18 years or older. The overall response rate was 49%. We examined the unadjusted effect of each independent variable on the likelihood of future participation in health-related surveys using univariate logistic regression and discerned the relative contribution of the different variables with multivariate logistic regression analysis. Respondents were asked to complete an average of 4.5 different surveys in the year before the current survey; approximately a quarter of the respondents perceived these surveys to be burdensome. The likelihood of future participation in health-related surveys was negatively related to good health status, a busy schedule, and perceptions that the surveys were too long. Respondents were more than twice as likely to indicate that they would participate in a future health-related survey if they knew the organization doing the survey. For health-related surveys, investigators should remain mindful of people's busy schedules and keep their surveys as short as possible. Further research is needed to clarify whether the decision to participate in a survey hinges more on knowing the organization paying to have a survey performed (the sponsor) or the survey vendor collecting the data.

    The whole of the Taurus region (a total area of 52 sq. deg.) has been observed by the Herschel SPIRE and PACS instruments at wavelengths of 70, 160, 250, 350 and 500 {\\mu}m as part of the Herschel Gould Belt Survey. In this paper we present the first results from the part of the Taurus region that includes the Barnard 18 and L1536 clouds. A new source-finding routine, the Cardiff Source-finding AlgoRithm (CSAR), is introduced, which is loosely based on CLUMPFIND, but that also generates a structure tree, or dendrogram, which can be used to interpret hierarchical clump structure in a complex region. Sources were extracted from the data using the hierarchical version of CSAR and plotted on a mass-size diagram. We found a hierarchy of objects with sizes in the range 0.024-2.7 pc. Previous studies showed that gravitationally bound prestellar cores and unbound starless clumps appeared in different places on the mass-size diagram. However, it was unclear whether this was due to a lack of instrumental dynamic range ...

    The VISTA Magellanic Cloud (VMC, PI M.R. Cioni) survey is collecting deep Ks-band time-series photometry of the pulsating variable stars hosted by the system formed by the two Magellanic Clouds (MCs) and the "bridge" connecting them. In this paper we present the first results for Classical Cepheids, from the VMC observations of two fields in the Large Magellanic Cloud (LMC). The VMC Ks-band light curves of the Cepheids are well sampled (12-epochs) and of excellent precision. We were able to measure for the first time the Ks magnitude of the faintest Classical Cepheids in the LMC (Ks\\sim17.5 mag), which are mostly pulsating in the First Overtone (FO) mode, and to obtain FO Period-Luminosity (PL), Period-Wesenheit (PW), and Period-Luminosity-Color (PLC) relations, spanning a whole period range from 0.25 to 6 days. Saturation limits our Ks measurements of the Fundamental mode (F) Cepheids to periods shorter than 15-20 days. Therefore, we have complemented our sample with literature data for brighter F Cepheids. ...

    The Global Oscillation Network Group (GONG) Project will place a network of instruments around the world to observe solar oscillations as continuously as possible for three years. The Project has now chosen the six network sites based on analysis of survey data from fifteen sites around the world. The chosen sites are: Big Bear Solar Observatory, California; Mauna Loa Solar Observatory, Hawaii; Learmonth Solar Observatory, Australia; Udaipur Solar Observatory, India; Observatorio del Teide, Tenerife; and Cerro Tololo Interamerican Observatory, Chile. Total solar intensity at each site yields information on local cloud cover, extinction coefficient, and transparency fluctuations. In addition, the performance of 192 reasonable networks assembled from the individual site records is compared using a statistical principal components analysis. An accompanying paper descibes the analysis methods in detail; here we present the results of both the network and individual site analyses. The selected network has a duty cycle of 93.3%, in good agreement with numerical simulations. The power spectrum of the network observing window shows a first diurnal sidelobe height of 3 x 10(exp -4) with respect to the central component, an improvement of a factor of 1300 over a single site. The background level of the network spectrum is lower by a factor of 50 compared to a single-site spectrum.

    Purpose: To determine the number of radiologists who currently have Internet access, their use patterns on the Internet for Radiology purposes, the web sites they would recommend, and the potential site access to the Internet that they would like to see in the future. In addition, this study analyzed the best way to find nationwide radiological sites and their content. Materials and Methods: In a nationwide survey, 854 Austrian radiologist were asked to fill out and return a questionnaire about Internet access, current problems, current and future use, which web site they recommend, and about the use of e-mail. Next, the available nationwide radiological sites were searched with seven major search engines using 37 different keywords, as well as by category search, and by searching for links on the homepages of the radiological departments of all Universities of Austria. Then, the offered information of the founded pages was classified in categories. Results: Of the 210 (24.6%) radiologists who returned the questionnaire, 154 (73%) had Internet access. Time expenditure was considered the main problem using the Internet. The Internet was used for literature research by 69% of the radiologists with Internet access, for e-mail by 60%, and for congress information by 57%. In future, 43% would like to read electronic journals more often and 39% would like to use the web more intensively for scientific congresses. At the present time, we found 17 radiological web sites in Austria. The most promising way to find these sites was to use the search engines Alta Vista and Hotbot. Fifteen (88%) sites offered information for patients, seven (41%) for radiologists, five (29%) for students, and four (24%) for researchers. Summary: Many radiologists in Austria already have Internet access, although time expenditure was considered the main problem with Internet use. Survey responses showed a need for electronic journals. To our point of view, Universities and radiological societies

    Multidetector CT (MDCT) scanners have contributed to the widespread use of CT in paediatric imaging. However, concerns are raised for the associated radiation exposure. Very few surveys on radiation exposure from MDCT studies in children are available. The aim of this study was to outline the status of radiation exposure in children from MDCT practice in Italy. In this retrospective multicentre study we asked Italian radiology units with an MDCT scanner with at least 16 slices to provide dosimetric and acquisition parameters of CT examinations in three age groups (1-5, 6-10, 11-15 years) for studies of head, chest and abdomen. The dosimetric results were reported in terms of third-quartile volumetric CT dose index (CTDI{sub vol}) (mGy), size-specific dose estimate (SSDE) (mGy), dose length product (DLP) (mGy cm), and total DLP for multiphase studies. These results were compared with paediatric European and adult Italian published data. A multivariate analysis assessed the association of CTDI{sub vol} with patient characteristics and scanning modalities. We collected data from 993 MDCT examinations performed at 25 centres. For age groups 1-5 years, 6-10 years and 11-15 years, the CTDI{sub vol}, DLP and total DLP values were statistically significantly below the values observed in our analogous national survey in adults, although the difference decreased with increasing age. CTDI{sub vol} variability among centres was statistically significant (variance = 0.07; 95% confidence interval = 0.03-0.16; P < 0.001). This study reviewed practice in Italian centres performing paediatric imaging with MDCT scanners. The variability of doses among centres suggests that the use of standardised CT protocols should be encouraged. (orig.)

    Full Text Available Abstract Background The Breast Health Surveys, conducted by the National Breast Cancer Centre (NBCC in 1996 and 2003, are designed to gain insight into the knowledge, attitudes and behaviours of a nationally representative sample of Australian women on issues relevant to breast cancer. In this article, we focus on major aspects of the design and present results on respondents' knowledge about mammographic screening. Methods The 2003 BHS surveyed English-speaking Australian women aged 30–69 without a history of breast cancer using computer-assisted telephone interviewing. Questions covered the following themes: knowledge and perceptions about incidence, mortality and risk; knowledge and behaviour regarding early detection, symptoms and diagnosis; mammographic screening; treatment; and accessibility and availability of information and services. Respondents were selected using a complex sample design involving stratification. Sample weights against Australian population benchmarks were used in all statistical analyses. Means and proportions for the entire population and by age group and area of residence were calculated. Statistical tests were conducted using a level of significance of 0.01. Results Of the 3,144 respondents who consented to being interviewed, 138 (4.4% had a previous diagnosis of breast cancer and were excluded leaving 3,006 completed interviews eligible for analysis. A majority of respondents (61.1% reported ever having had a mammogram and 29.1% identified mammography as being the best way of finding breast cancer. A majority of women (85.9% had heard of the BreastScreen Australia (BSA program, the national mammographic screening program providing free biennial screening mammograms, with 94.5% believing that BSA attendance was available regardless of the presence or absence of symptoms. There have been substantial gains in women's knowledge about mammographic screening over the seven years between the two surveys. Conclusion The

    Full Text Available Measurement and analysis of noise level in various frequency bands was carried out in a textile factory. It was shown that the noise level in various working places, particularly in the weaving workshop, was quite excessive comparing to the standards and so, it may very likely result in producing hearing loss in the workers. To determine the hearing loss of the workers due to excessive noise, 136 weavers were randomly selected and examined. However, the number of samples was not large enough to give reliable results. It was concluded that the intensive noise level in the weaving workshops may have produced considerable hearing loss in the workers. Large the expo­sure to noise, more the hearing loss was observed.

  6. Time allocation shifts and pollutant exposure due to traffic congestion: an analysis using the national human activity pattern survey.

    Science.gov (United States)

    Zhang, Kai; Batterman, Stuart A

    2009-10-15

    Traffic congestion increases air pollutant exposures of commuters and urban populations due to the increased time spent in traffic and the increased vehicular emissions that occur in congestion, especially "stop-and-go" traffic. Increased time in traffic also decreases time in other microenvironments, a trade-off that has not been considered in previous time activity pattern (TAP) analyses conducted for exposure assessment purposes. This research investigates changes in time allocations and exposures that result from traffic congestion. Time shifts were derived using data from the National Human Activity Pattern Survey (NHAPS), which was aggregated to nine microenvironments (six indoor locations, two outdoor locations and one transport location). After imputing missing values, handling outliers, and conducting other quality checks, these data were stratified by respondent age, employment status and period (weekday/weekend). Trade-offs or time-shift coefficients between time spent in vehicles and the eight other microenvironments were then estimated using robust regression. For children and retirees, congestion primarily reduced the time spent at home; for older children and working adults, congestion shifted the time spent at home as well as time in schools, public buildings, and other indoor environments. Changes in benzene and PM(2.5) exposure were estimated for the current average travel delay in the U.S. (9 min day(-1)) and other scenarios using the estimated time shifts coefficients, concentrations in key microenvironments derived from the literature, and a probabilistic analysis. Changes in exposures depended on the duration of the congestion and the pollutant. For example, a 30 min day(-1) travel delay was determined to account for 21+/-12% of current exposure to benzene and 14+/-8% of PM(2.5) exposure. The time allocation shifts and the dynamic approach to TAPs improve estimates of exposure impacts from congestion and other recurring events.

    The ESO Imaging Survey (EIS) presented in early issues of the Messenger, and with up-to-date information on the ongoing observations available on the Web (http://www.eso.org/eis), is a concerted effort by ESO and the Member State community to provide targets for the first year of operation of the VLT. It consists of two parts: a relatively wide-angle survey (EIS-WIDE) to cover four pre-selected patches of sky, 6 square degrees each, spread in right ascension to search for distant clusters and quasars and a deep, multicolor survey of four optical (SUSI-2) and two infrared (SOFI) covering the HST/Hubble Deep Field South (HDFS) and its flanking fields (EIS-DEEP). From the start, the main challenge has been to carry out a public survey in a limited amount of time requiring observations, software development and data reduction with the goal of distributing the survey data products before the call for proposal for the VLT. To cope with this one-year timetable, a novel type of collaboration between ESO and the commu...

    We observed an area of 10 deg^2 of the Large Magellanic Cloud using the Infrared Camera on board AKARI. The observations were carried out using five imaging filters (3, 7, 11, 15, and 24 micron) and a dispersion prism (2 -- 5 micron, $\\lambda / \\Delta\\lambda$ $\\sim$ 20) equipped in the IRC. This paper describes the outline of our survey project and presents some initial results using the imaging data that detected over 5.9x10^5 near-infrared and 6.4x10^4 mid-infrared point sources. The 10 $\\sigma$ detection limits of our survey are about 16.5, 14.0, 12.3, 10.8, and 9.2 in Vega-magnitude at 3, 7, 11, 15, and 24 micron, respectively. The 11 and 15 micron data, which are unique to AKARI IRC, allow us to construct color-magnitude diagrams that are useful to identify stars with circumstellar dust. We found a new sequence in the color-magnitude diagram, which is attributed to red giants with luminosity fainter than that of the tip of the first red giant branch. We suggest that this sequence is likely to be related ...

    Full Text Available The Binational Arsenic Exposure Survey (BAsES was designed to evaluate probable arsenic exposures in selected areas of southern Arizona and northern Mexico, two regions with known elevated levels of arsenic in groundwater reserves. This paper describes the methodology of BAsES and the relationship between estimated arsenic intake from beverages and arsenic output in urine. Households from eight communities were selected for their varying groundwater arsenic concentrations in Arizona, USA and Sonora, Mexico. Adults responded to questionnaires and provided dietary information. A first morning urine void and water from all household drinking sources were collected. Associations between urinary arsenic concentration (total, organic, inorganic and estimated level of arsenic consumed from water and other beverages were evaluated through crude associations and by random effects models. Median estimated total arsenic intake from beverages among participants from Arizona communities ranged from 1.7 to 14.1 µg/day compared to 0.6 to 3.4 µg/day among those from Mexico communities. In contrast, median urinary inorganic arsenic concentrations were greatest among participants from Hermosillo, Mexico (6.2 µg/L whereas a high of 2.0 µg/L was found among participants from Ajo, Arizona. Estimated arsenic intake from drinking water was associated with urinary total arsenic concentration (p < 0.001, urinary inorganic arsenic concentration (p < 0.001, and urinary sum of species (p < 0.001. Urinary arsenic concentrations increased between 7% and 12% for each one percent increase in arsenic consumed from drinking water. Variability in arsenic intake from beverages and urinary arsenic output yielded counter intuitive results. Estimated intake of arsenic from all beverages was greatest among Arizonans yet participants in Mexico had higher urinary total and inorganic arsenic concentrations. Other contributors to urinary arsenic concentrations should be evaluated.

    2015-08-01

    The Attitudes of Consumers Toward Health, Cough, and Cold (ACHOO) survey was developed to better inform health care providers on the natural history and impact of common cold and cough, and related consumer experience and behaviors. Randomly selected US Internet/mobile device users were invited to participate in an online survey (N = 3333) in October 2012. Response quotas modeled upon 2010 US Census data ensured a demographically representative sample. To reduce potential bias from the quota design, 75% of the completed surveys were randomly selected as the primary analysis pool. Survey questions assessed participant demographics, frequency and duration of cough/cold symptoms, impact of symptoms on daily life, treatment preferences, and knowledge about cough/cold pathophysiology. In the past year, 84.6% of respondents had experienced at least one cold. Colds typically started with sore/scratchy throat (39.2%), nasal congestion (9.8%), and runny nose (9.3%) and lasted 3-7 days. Cough, the most common cold symptom (73.1%), had a delayed onset (typically 1-5 days after cold onset) and a long duration (>6 days in 35.2%). Nasal congestion and cough were the most bothersome symptoms. Many respondents waited until symptoms were 'bad enough' (42.6%) or multiple symptoms were present (20.2%) before using nonprescription medications. Drivers of choice included effectiveness in relieving symptoms, safety, and past experience. Respondents rarely consulted clinicians regarding treatment, and more than three-quarters had never received instructions from a clinician on how to choose a nonprescription cough/cold medication. Misperceptions regarding etiology and treatment of the common cold were prevalent. The main limitation is potential recall bias, since respondents had to recall cough/cold episodes over the prior year. The ACHOO survey confirms that cold is a common, bothersome experience and that there are gaps in consumers' knowledge of pathophysiology and appropriate

    Odors emitted from US Midwest hog production facilities present farmers, residents, and state regulatory agencies with a set of complex challenges. To predict odor exposure from multiple swine production sources simultaneously, and to determine siting recommendations for proposed new or enlarged hog facilities, researchers at Iowa State University designed the community assessment model for odor dispersion (CAM). A three-county citizen survey conducted in Iowa examined the level of hypothetical social acceptance of the modeling process, and level of trust in CAM results. While 69 % of respondents approved of modeling as a way to determine the most socially appropriate location for production sites, only 35 % would trust the results if potential odor exposure from a new facility were proposed to be built near their home. We analyzed approval of the CAM model, and level of trust, across a number of demographic, attitudinal, and belief factors regarding environmental quality and the hog industry. Overall, trust in CAM was uneven and varied across respondents. Those residents who would not trust CAM tended to be more concerned with environmental quality and less inclined to believe that the hog industry is critically important economically. Those who would not trust CAM results also had significantly more direct experience with odors. Findings point to predominantly positive, yet equivocal acceptance of CAM results among the citizenry, which is not unexpected given conflict typical of siting decisions in industry and waste disposal arenas. Recommendations are offered regarding the interaction of trust, beliefs and attitudes and the utility of CAM.

    The US Geological Survey and the State geological surveys of many coal-bearing States recently completed a new assessment of the top producing coal beds and coal zones in five major producing coal regions the Appalachian Basin, Gulf Coast, Illinois Basin, Colorado Plateau, and Northern Rocky Mountains and Great Plains. The assessments, which focused on both coal quality and quantity, utilized geographic information system technology and large databases. Over 1,600,000 million short tons of coal remain in over 60 coal beds and coal zones that were assessed. Given current economic, environmental, and technological restrictions, the majority of US coal production will occur in that portion of the assessed coal resource that is lowest in sulfur content. These resources are concentrated in parts of the central Appalachian Basin, Colorado Plateau, and the Northern Rocky Mountains. ?? Elsevier Science B.V. All rights reserved.

    The Americans with Disabilities Act (ADA), enacted in 1990, has had a significant impact on the way many institutions, including libraries, do business. The Association of Research Libraries surveyed its members in 1991 to determine the effect of this legislation, and the author conducted a similar survey in 1995 to learn what progress academic health sciences libraries have made in serving the needs of people with disablities. A questionnaire was mailed to 131 members of the Association of Academic Health Sciences Library Directors. Nearly three-quarters of respondents reported elimination of physical barriers. The most common services provided are retrieval of materials from the stacks and photocopy assistance. Much less attention has been paid to the use of adaptive technology that allows disabled users to search a library's online catalog and databases; special technology is often provided by another unit on campus but there seems to be little coordination with library services Few libraries have assigned responsibility for disability services to a specific staff member and even fewer have done a formal assessment of the need for special services. The issues identified by the survey should challenge academic health sciences libraries to examine their status regarding compliance with ADA legislation.

    Pisinger Charlotta

    2012-09-01

    Full Text Available Abstract Background Exposure to second hand smoke (SHS is an important preventable cause of morbidity and mortality in children. We hypothesised that there has been a growth in social inequality in children’s exposure to SHS at home over time. The purpose of this study was to investigate temporal change in smoking in homes including children, focusing on the socioeconomic differences. Methods Data is from a repeated cross-sectional survey, ‘Health Profiles of the Capital Region of Denmark’ conducted in 2007 and 2010, in 29 municipalities. The response rate was 52.3%, in both surveys. Our study included persons aged 25 to 64, living with children ≤15 years of age; N=9,289 in 2007 and 12,696 in 2010. Analyses were weighted for size of municipality and for non-response, which was higher among men and among persons who were younger, had a lower income, were living alone, were unemployed, and/or were of an ethnicity other than Danish. Regression analyses were used to investigate smoking in homes including children across parent/adult education levels, focusing on temporal changes. Results There were significant large socioeconomic differences in both 2007 and 2010. In 2010 it was more than 11 times more likely for a child to be exposed to SHS at home if the parent had very low education than if they were highly educated (p Conclusions Marked social inequalities in children’s exposure to SHS and a significant temporal decrease in exposure, independent of the education level of the parent/adult, were found in repeated large cross-sectional population-based studies. Social disparities have persisted over time, but not increased. Both clinical and population policy interventions will be needed in order to control child SHS exposure. We call for legislative protection of children from tobacco smoke inside their home as a supplement to parental education and support for smoking cessation.

    The Institute of Medicine noted that current food and beverage marketing practices promote unhealthful diets. However, little public health research has been conducted on food marketing directed toward adolescents, especially using caregiver- and adolescent-reported data. We assessed perceived frequency of food/beverage advertising exposure and common locations of food/beverage marketing exposure for adolescents using 2012 Summer ConsumerStyles and YouthStyles survey data on US adults ≥18 years of age and their children ages 12-17 (n=847), respectively. Exposure to advertisements for fast food, soda, fruit drinks, sports drinks, energy drinks, and bottled water were categorized as marketing most frequently on television followed by at the supermarket. Our study showed that adolescents reported lower frequency of food and beverage advertising exposure than their caregivers. Further research may be needed to verify self-reported exposure data on food and beverage advertising as a way to obtain data for use in research on its relationship with diet quality and obesity.

    Riding a motorcycle under the influence of alcohol is a dangerous activity, especially considering the high vulnerability of motorcyclists. The present research investigates the factors that affect the declared frequency of drink-riding among motorcyclists in Europe and explores regional differences. Data were collected from the SARTRE-4 (Social Attitudes to Road Traffic Risk in Europe) survey, which was conducted in 19 countries. A total sample of 4483 motorcyclists was interviewed by using a face-to-face questionnaire. The data were analyzed by means of multilevel ordered logit models. The results revealed significant regional differences (between Northern, Eastern and Southern European countries) in drink-riding frequencies in Europe. In general, declared drinking and riding were positively associated with gender (males), increased exposure, underestimation of risk, friends' behaviour, past accidents and alcohol ticket experience. On the other hand, it was negatively associated with underestimation of the amount of alcohol allowed before driving, and support for more severe penalties.

    Background: Environmental exposures to phthalates, particularly high-molecular-weight (HMW) phthalates, are suspected to contribute to allergy. Objective: We assessed whether phthalate metabolites are associated with allergic symptoms and sensitization in a large nationally representative sample. Methods: We used data on urinary phthalate metabolites and allergic symptoms (hay fever, rhinitis, allergy, wheeze, asthma) and sensitization from participants ≥ 6 years of age in the National Health and Nutrition Examination Survey (NHANES) 2005–2006. Allergen sensitization was defined as a positive response to at least one of 19 specific IgE antigens (≥ 0.35 kU/L). Odds ratios (ORs) per one log10 unit change in phthalate concentration were estimated using logistic regression adjusting for age, race, body mass index, gender, creatinine, and cotinine. Separate analyses were conducted for children (6–17 years of age) and adults. Results: The HMW phthalate metabolite monobenzyl phthalate (MBzP) was the only metabolite positively associated with current allergic symptoms in adults (wheeze, asthma, hay fever, and rhinitis). Mono-(3-carboxypropyl) phthalate and the sum of diethylhexyl phthalate metabolites (both representing HMW phthalate exposures) were positively associated with allergic sensitization in adults. Conversely, in children, HMW phthalate metabolites were inversely associated with asthma and hay fever. Of the low-molecular-weight phthalate metabolites, monoethyl phthalate was inversely associated with allergic sensitization in adults (OR = 0.79; 95% CI: 0.70, 0.90). Conclusion: In this cross-sectional analysis of a nationally representative sample, HMW phthalate metabolites, particularly MBzP, were positively associated with allergic symptoms and sensitization in adults, but there was no strong evidence for associations between phthalates and allergy in children 6–17 years of age.

    2017-01-01

    We present early analysis of the Hα survey of the Magellanic Stream using the Wisconsin H-Alpha Mapper (WHAM). The neutral component of the Stream extends some 200° across the sky (Nidever et al. 2010). However, the full extent of the ionized gas has not been mapped in detail. Previous studies (e.g., Putman et al. 2003; Weiner & Williams 1996) suggest that ionized gas is likely to be found all along the length of the Stream, and may extend beyond the current neutral boundaries as traced by 21 cm. Barger et al. (2013) used WHAM to map ionized gas throughout the Magellanic Bridge between the Magellanic Clouds. Although ionized emission tracks the neutral emission for the most part, it often spans a few degrees away from the H I at slightly offset velocities. Additionally, Fox et al. (2014) find evidence in an absorption line study that the tidal debris in the Magellanic System contains twice as much ionized gas as neutral material and may extend 30° away from 21-cm sensitivity boundaries. We are now compiling the first comprehensive picture of the ionized component of the Magellanic Stream using WHAM's unprecedented sensitivity to trace diffuse emission (~tens of mR), its velocity resolution (12 km/s) to separate the Stream from the Milky Way, and its multiwavelength capabilities (e.g., [S II] and [N II]) to examine the physical conditions of the gas. Much of the data along the primary axis of the Stream has been collected for the first phase of this extensive study, a complete kinematic Hα survey of the Stream. We present survey progress, challenges in extracting Stream emission, and first-look kinematic maps at select positions along the Stream.

    Although perhaps the most common worker-management structure, there has been surprisingly little research on describing and evaluating the characteristics of health and safety committees. A survey of 380 health and safety committee members from 176 manufacturing workplaces was supplemented with administrative data and compared with reported workers' compensation rates. Survey respondents also reported perceptions of overall safety, committee, effectiveness, committee activities, and "best practices." Extensive descriptive data is presented, including a mean of 8.7 members per committee spending 1,167 hr per year on committee business for an estimate of $40,500 worth of time per committee. Higher speed to correct action items, a focus on ergonomics, and planning for safety training was associated with lower injury rates. The discrepancy between managers and hourly committee members in estimating overall safety was strongly positively associated with injury rates. Communications and worker involvement may be important to address discrepancy issues. Prospective studies are needed to distinguish directionality of associations.

    We present two galaxy shape catalogues from the Dark Energy Survey Year 1 data set, covering 1500 square degrees with a median redshift of $0.59$. The catalogues cover two main fields: Stripe 82, and an area overlapping the South Pole Telescope survey region. We describe our data analysis process and in particular our shape measurement using two independent shear measurement pipelines, METACALIBRATION and IM3SHAPE. The METACALIBRATION catalogue uses a Gaussian model with an innovative internal calibration scheme, and was applied to $riz$-bands, yielding 34.8M objects. The IM3SHAPE catalogue uses a maximum-likelihood bulge/disc model calibrated using simulations, and was applied to $r$-band data, yielding 21.9M objects. Both catalogues pass a suite of null tests that demonstrate their fitness for use in weak lensing science. We estimate the 1$\\sigma$ uncertainties in multiplicative shear calibration to be $0.013$ and $0.025$ for the METACALIBRATION and IM3SHAPE catalogues, respectively.

    An online survey utilizing Survey Monkey linked through the American Association of Zoo Veterinarians listserve examined current practices in megavertebrate analgesia. Data collected included drugs administered, dosing regimens, ease of administration, efficacy, and adverse events. Fifty-nine facilities (38 housing elephants, 33 housing rhinoceroses) responded. All facilities administered nonsteroidal anti-inflammatory drugs (NSAIDs), with phenylbutazone (0.25-10 mg/kg) and flunixin meglumine (0.2-4 mg/kg) being most common. Efficacy was reported as "good" to "excellent" for these medications. Opioids were administered to elephants (11 of 38) and rhinoceroses (7 of 33), with tramadol (0.5-3.0 mg/kg) and butorphanol (0.05-1.0 mg/kg) being most common. Tramadol efficacy scores were highly variable in both elephants and rhinoceroses. While drug choices were similar among institutions, substantial variability in dosing regimens and reported efficacy between and within facilities indicates the need for pharmacokinetic studies and standardized methods of analyzing response to treatment to establish dosing regimens and clinical trials to establish efficacy and safety.

    Debris discs are a consequence of the planet formation process and constitute the fingerprints of planetesimal systems. Their solar system's counterparts are the asteroid and Edgeworth-Kuiper belts. The DUNES survey aims at detecting extra-solar analogues to the Edgeworth-Kuiper belt around solar-type stars, putting in this way the solar system into context. The survey allows us to address some questions related to the prevalence and properties of planetesimal systems. We used {\\it Herschel}/PACS to observe a sample of nearby FGK stars. Data at 100 and 160 $\\mu$m were obtained, complemented in some cases with observations at 70 $\\mu$m, and at 250, 350 and 500 $\\mu$m using SPIRE. The observing strategy was to integrate as deep as possible at 100 $\\mu$m to detect the stellar photosphere. Debris discs have been detected at a fractional luminosity level down to several times that of the Edgeworth-Kuiper belt. The incidence rate of discs around the DUNES stars is increased from a rate of $\\sim$ 12.1% $\\pm$ 5% befo...

    Workplace smoking cessation programs can increase smoking cessation rates, improve employee health, reduce exposure to second-hand smoke, and decrease costs. To assist with the development of such programs, we conducted a Global Workplace Smoking Survey to collect information on workplace attitudes towards smoking cessation programs. Data were collected from 1,403 employers (smoking and non-smoking) and 3,525 smoking employees participating in surveys in 14 countries in Asia, Europe, and South America in 2007. Results were weighted to ensure that they were representative of smokers and employers at companies with the specified number of employees. More than two-thirds of employers (69%) but less than half of employees (48%) indicated that their company should help employees with smoking cessation. Approximately two-thirds of employees and 81% of employers overall felt that smoke-free policies encourage cessation, but fewer individuals from Europe (vs. from Asia or South America) agreed with this. In companies with a smoke-free policy, 76% of employees and 80% of employers felt that their policy had been somewhat, very, or extremely effective in motivating employees to quit or reduce smoking. Employers and employees differed substantially regarding appropriate methods for encouraging cessation, with more employees favouring financial incentives and more employers favouring education. Both employees and employers value smoke-free workplace programs and workplace cessation support activities, although many would like their companies to offer more support. These results will be useful for organizations exploring means of facilitating smoking cessation amongst employees.

    We present the initial results of a 40 night contiguous ground-based campaign of time series photometric observations of a 1.39 sq. deg field located within the NASA Kepler mission field of view. The goal of this pre-launch survey was to search for transiting extrasolar planets and to provide independent variability information of stellar sources. We have gathered a data set containing light curves of 54,687 stars from which we have created a statistical sub-sample of 13,786 stars between 14< r <18.5 and have statistically examined each light curve to test for variability. We present a summary of our preliminary photometric findings including the overall level and content of stellar variability in this portion of the Kepler field and give some examples of unusual variable stars found within. We present a preliminary catalog of 2,457 candidate variable stars, of which 776 show signs of periodicity. We also present three potential exoplanet candidates, all of which should be observable in detail by the Ke...

    The National Geodetic Survey conducted a second Geoid Slope Validation Survey in the summer of 2014 (GSVS14). The survey took place in Iowa along U.S Route 30. The survey line is approximately 200 miles long (325 km), extending from Denison, IA to Cedar Rapids, IA. There are over 200 official survey bench marks. A leveling survey was performed, conforming to 1st order, class II specifications. A GPS survey was performed using 24 to 48 hour occupations. Absolute gravity, relative gravity, and gravity gradient measurements were also collected during the survey. In addition, deflections of the vertical were acquired at 200 eccentric survey benchmarks using the Compact Digital Astrometric Camera (CODIAC) camera. This paper presents the preliminary results of the survey, including the accuracy analysis of the leveling data, GPS ellipsoidal heights, and the deflections of the vertical which serves as an independent data set in addition to the GPS/leveling implied geoid heights.

    We describe two ground based observing campaigns aimed at building a grid of approximately 200 spectrophotometric standard stars (SPSS), with an internal ~1% precision and tied to Vega within ~3%, for the absolute flux calibration of data gathered by Gaia, the ESA astrometric mission. The criteria for the selection and a list of candidates are presented, together with a description of the survey strategy and the adopted data analysis methods. We also discuss a short list of notable rejected SPSS candidates and difficult cases, based on identification problems, literature discordant data, visual companions, and variability. In fact, all candidates are also monitored for constancy (within \\pm5 mmag, approximately). In particular, we report on a CALSPEC standard, 1740346, that we found to be a delta Scuti variable during our short-term monitoring (1-2 h) campaign.

    Durand, Arnaud; Makowsky, Johann; More, Malika

    2009-01-01

    In 1952, Heinrich Scholz published a question in the Journal of Symbolic Logic asking for a characterization of spectra, i.e., sets of natural numbers that are the cardinalities of finite models of first order sentences. G\\"unter Asser asked whether the complement of a spectrum is always a spectrum. These innocent questions turned out to be seminal for the development of finite model theory and descriptive complexity. In this paper we survey developments over the last 50-odd years pertaining to the spectrum problem. Our presentation follows conceptual developments rather than the chronological order. Originally a number theoretic problem, it has been approached in terms of recursion theory, resource bounded complexity theory, classification by complexity of the defining sentences, and finally in terms of structural graph theory. Although Scholz' question was answered in various ways, Asser's question remains open. One appendix paraphrases the contents of several early and not easily accesible papers by G. Ass...

    Nursing informatics (NI) can help provide effective and safe healthcare. This study aimed to describe current research trends in NI. In the summer 2015, the IMIA-NI Students Working Group created and distributed an online international survey of the current NI trends. A total of 402 responses were submitted from 44 countries. We identified a top five NI research areas: standardized terminologies, mobile health, clinical decision support, patient safety and big data research. NI research funding was considered to be difficult to acquire by the respondents. Overall, current NI research on education, clinical practice, administration and theory is still scarce, with theory being the least common. Further research is needed to explain the impact of these trends and the needs from clinical practice.

    To assess the effect of neurology residency education as trainees advance into independent practice, the American Academy of Neurology (AAN) elected to survey all graduating neurology residents at time of graduation and in 3-year cycles thereafter. A 22-question survey was sent to all neurology residents completing residency training in the United States in 2007. Of 523 eligible residents, 285 (54.5%) responded. Of these, 92% reported good to excellent quality teaching of basic neurology from their faculty; however, 47% noted less than ideal training in basic neuroscience. Two-thirds indicated that the Residency In-service Training Examination was used only as a self-assessment tool, but reports of misuse were made by some residents. After residency, 78% entered fellowships (with 61% choosing a fellowship based on interactions with a mentor at their institution), whereas 20% entered practice directly. After adjustment for the proportion of residents who worked before the duty hour rules were implemented and after their implementation, more than half reported improvement in quality of life (87%), education (60%), and patient care (62%). The majority of international medical graduates reported wanting to stay in the United States to practice rather than return to their country of residence. Neurology residents are generally satisfied with training, and most entered a fellowship. Duty hour implementation may have improved resident quality of life, but reciprocal concerns were raised about impact on patient care and education. Despite the majority of international trainees wishing to stay in the United States, stricter immigration laws may limit their entry into the future neurology workforce.

    We present the data acquisition strategy and characterization procedures for the Canada-France Ecliptic Plane Survey (CFEPS), a sub-component of the Canada-France-Hawaii Telescope Legacy Survey. The survey began in early 2003 and as of summer 2005 has covered 430 square degrees of sky within a few degrees of the ecliptic. Moving objects beyond the orbit of Uranus are detected to a magnitude limit of $m_R$=23 -- 24 (depending on the image quality). To track as large a sample as possible and avoid introducing followup bias, we have developed a multi-epoch observing strategy that is spread over several years. We present the evolution of the uncertainties in ephemeris position and orbital elements as the objects progress through the epochs. We then present a small 10-object sample that was tracked in this manner as part of a preliminary survey starting a year before the main CFEPS project. We describe the CFEPS survey simulator, to be released in 2006, which allows theoretical models of the Kuiper Belt to be comp...

    Population exposure to food and nutrients can be estimated from household food purchases, but store surveys of foods and their composition are more available, less costly and might provide similar information. Our aim was to compare estimates of nutrient exposure from a store survey of packaged food with those from household panel food purchases. A cross-sectional store survey of all packaged foods for sale in two major supermarkets was undertaken in Auckland, New Zealand, between February and May 2012. Longitudinal household food purchase data (November 2011 to October 2012) were obtained from the nationally representative, population-weighted New Zealand Nielsen HomeScan® panel. Data on 8440 packaged food and non-alcoholic beverage products were collected in the store survey. Food purchase data were available for 1229 households and 16 812 products. Store survey data alone produced higher estimates of exposure to Na and sugar compared with estimates from household panel food purchases. The estimated mean difference in exposure to Na was 94 (95 % CI 72, 115) mg/100 g (20 % relative difference; Pfood purchases, store survey data provided a reasonable estimate of average population exposure to key nutrients from packaged foods. However, caution should be exercised in using such data to estimate population exposure to Na and sugar and in generalising these findings to other countries, as well as over time.

    We present constraints on the abundance of carbon-monoxide in the early Universe from the CO Power Spectrum Survey (COPSS). We utilize a data set collected between 2005 and 2008 using the Sunyaev-Zel'dovich Array (SZA), which were previously used to measure arcminute-scale fluctuations of the CMB. This data set features observations of 44 fields, covering an effective area of 1.7 square degrees, over a frequency range of 27 to 35 GHz. Using the technique of intensity mapping, we are able to probe the CO(1-0) transition, with sensitivity to spatial modes between $k=0.5{-}2\\ h\\,\\textrm{Mpc}^{-1}$ over a range in redshift of $z=2.3{-}3.3$, spanning a comoving volume of $3.6\\times10^{6}\\ h^{-3}\\,\\textrm{Mpc}^{3}$.

    In most Western nations, the medical oncologist plays a significant role in the administration of systemic therapy for lung cancer. In Japan however, treatment for lung cancer has historically been provided by pulmonologists and thoracic surgeons. A comparison of the management of advanced disease between Japan and other nations has not been described. An online, self-administered, international survey was sent to 3907 active members of the American Society of Clinical Oncology. Eligible participants were degreed physicians who prescribed systemic agents for adult cancer treatment within the past five years. In total, 281 respondents answered the questions regarding management of lung cancer. Thorough analysis demonstrated that pulmonologists play a significant role in Japan and the Netherlands, where the role of oncologic specialists is not well established. Of note, all the respondents from the Netherlands reported that pulmonary medicine primarily manages systemic chemotherapy in stage IV, adjuvant chemotherapy, and targeted therapy. We found there are several nations where non-oncologic specialists play a critical role in the systemic treatment of lung cancer. We expect this practice pattern to continue until the global adoption of the oncologic specialty role. Copyright © 2017 The Japanese Respiratory Society. Published by Elsevier B.V.

    Registered dietitians are the nutrition experts in America. As such, their opinions about using technology-based nutrition games as teaching tools are important. The purpose of this study was to query registered dietitians about their experience and recommendations for topics, age, and platforms for future nutrition game development. The author gave a 1-hour talk to two state dietetic conference groups about nutrition games and their efficacy, concerns, and hopes and opportunities for their future as viable nutrition teaching tools. After the talks attendees completed a five-question survey about nutrition games, including if they played nutrition games, if they thought games could possibly help in their work, and preferences for topics, ages, and platforms for which they wanted to see priority development. Although only 4% of respondents played nutrition games, 79% thought they could be of benefit, and 21% felt that "maybe" they could be beneficial educational tools. Games on all nutrition topics were welcome, with preference for computers and smartphone apps. After a lengthy presentation on the new genre of technology-based nutrition games, registered dietitians reported that they are open to using technology-based nutrition education apps and feel they could have some benefit in educating the public about nutrition, even though dietitians presently have little experience with them. The talk was successful in informing dietitians about this new game genre, and their suggestions for topics, target ages, and tech platforms will be helpful to nutrition game developers and designers.

  10. Factors affecting occupational exposure to needlestick and sharps injuries among dentists in Taiwan: a nationwide survey.

    Directory of Open Access Journals (Sweden)

    Hsin-Chung Cheng

    Full Text Available BACKGROUND: Although the risks of needlestick and sharps injuries (NSIs for dentists are well recognized, most papers published only described the frequency of occupational exposure to NSIs. Less has been reported assessing factors contributing to exposure to NSIs. The purpose of this study was to update the epidemiology of NSIs among dentists in Taiwan and identify factors affecting NSIs in order to find preventive strategies. METHODOLOGY/PRINCIPAL FINDINGS: A nationwide survey was conducted in dentists at 60 hospitals and 340 clinics in Taiwan. The survey included questions about factors supposedly affecting exposure to NSIs, such as dentist and facility characteristics, knowledge and attitudes about infectious diseases, and practices related to infection control. Univariate and multivariate logistic regression analyses were conducted to determine the association between risk factors and exposure to NSIs. In total, 434 (74.8% of 580 dentists returned the survey questionnaires, and 100 (23.0% reported that they had experienced more than one NSI per week. Our data showed that the risk of occupational NSIs is similarly heightened by an older age (odds ratio [OR], 3.18; 95% confidence interval [CI], 1.62-6.25, more years in practice (OR, 2.57; 95% CI, 1.41-4.69, working in clinics (OR, 1.73; 95% CI, 1.08-2.77, exhibiting less compliance with infection-control procedures (OR, 1.82; 95% CI, 1.04-3.18, having insufficient knowledge of blood-borne pathogens (OR, 1.67; 95% CI, 1.04-2.67, and being more worried about being infected by blood-borne pathogens (OR, 1.82; 95% CI, 1.05-3.13. CONCLUSIONS/SIGNIFICANCE: High rates of NSIs and low compliance with infection-control procedures highly contribute to the chance of acquiring a blood-borne pathogen infection and threaten occupational safety. This study reveals the possible affecting factors and helps in designing prevention strategies for occupational exposure to NSIs.

    2007-03-01

    Full Text Available Abstract 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

This survey will cover the entire sky visible to the Green Bank Telescope ($\\delta > -40^\\circ$, or 82% of the sky) and outside of the Galactic Plane will be sensitive enough to detect slow pulsars and low dispersion measure ($<$30 $\\mathrm{pc\\,cm^{-3}}$) millisecond pulsars (MSPs) with a 0.08 duty cycle down to 1.1 mJy. For pulsars with a spectral index of $-$1.6, we will be 2.5 times more sensitive than previous and ongoing surveys over much of our survey region. Here we describe the survey, the data analysis pipeline, initial discovery parameters for 62 pulsars, and timing solutions for 5 new pulsars. PSR J0214$+$5222 is an MSP in a long-period (512 days) orbit a...

    To evaluate the radiation dose in routine multidetector computed tomography (MDCT) examinations in Italian population. This was a retrospective multicentre study included 5,668 patients from 65 radiology departments who had undergone common CT protocols: head, chest, abdomen, chest-abdomen-pelvis (CAP), spine and cardiac. Data included patient characteristics, CT parameters, volumetric CT dose index (CTDI{sub vol}) and dose length product (DLP) for each CT acquisition phase. Descriptive statistics were calculated, and a multi-regression analysis was used to outline the main factors affecting exposure. The 75th percentiles of CTDI{sub vol} (mGy) and DLP (mGy cm) for whole head were 69 mGy and 1,312 mGy cm, respectively; for chest, 15 mGy and 569 mGy cm; spine, 42 mGy and 888 mGy cm; cardiac, 7 mGy and 131 mGy cm for calcium score, and 61 mGy and 1,208 mGy cm for angiographic CT studies. High variability was present in the DLP of abdomen and CAP protocols, where multiphase examinations dominated (71 % and 73 % respectively): for abdomen, 18 mGy, with 555 and 920 mGy cm in abdomen and abdomen-pelvis acquisitions respectively; for CAP, 17 mGy, with 508, 850 and 1,200 mGy cm in abdomen, abdomen-pelvis and CAP acquisitions respectively. The results of this survey could help in the definition of updated diagnostic reference levels (DRL). (orig.)

    Full Text Available Abstract Background Research on the effect of survey timing on patient-reported experiences and patient satisfaction with health services has produced contradictory results. The objective of this study was thus to assess the association between survey timing and patient-reported experiences with hospitals. Methods Secondary analyses of a national inpatient experience survey including 63 hospitals in the 5 health regions in Norway during the autumn of 2006. 10,912 (45% patients answered a postal questionnaire after their discharge from hospital. Non-respondents were sent a reminder after 4 weeks. Multilevel linear regression analysis was used to assess the association between survey timing and patient-reported experiences, both bivariate analysis and multivariate analysis controlling for other predictors of patient experiences. Results Multivariate multilevel regression analysis revealed that survey time was significantly and negatively related to three of six patient-reported experience scales: doctor services (Beta = -0.424, pp p Conclusions Survey time was significantly and negatively related to three of the six scales for patient-reported experiences with hospitals. Large differences in survey time across hospitals could be problematic for between-hospital comparisons, implying that survey time should be considered as a potential adjustment factor. More research is needed on this topic, including studies with other population groups, other data collection modes and a longer time span.

    Full Text Available Abstract Background Higher exposure to outdoor air pollution is associated with increased cardiopulmonary deaths, but there is limited evidence about the association between outdoor air pollution and diagnosed cardiovascular disease. Our study aimed to estimate the size of the association between long term exposure to outdoor air pollution and prevalent cardiovascular disease. Methods We carried out a cross-sectional analysis of data on more than 19,000 white adults aged 45 and older who participated in three representative surveys of the English population in 1994, 1998 and 2003, examining the relationship between self-reported doctor-diagnosed cardiovascular disease and exposure to outdoor air pollutants using multilevel regression techniques and meta-analysis. Results The combined estimates suggested that an increase of 1 μg m-3 in concentration of particulate matter less than 10 microns in diameter was associated with an increase of 2.9% (95% CI -0.6% to 6.5% in prevalence of cardiovascular disease in men, and an increase of 1.6% (95%CI -2.1% to 5.5% in women. The year-specific analyses showed strongly positive associations in 2003 between odds of cardiovascular disease in both men and women and exposure to particulate matter but not in 1994 or 1998. We found no consistent associations between exposure to gaseous air pollutants and doctor-diagnosed cardiovascular disease. Conclusion The associations of prevalent cardiovascular disease with concentration of particulate matter less than 10 microns in diameter, while only weakly positive, were consistent with the effects reported in cohort studies. The results provide evidence of the size of the association between particulate air pollution and the prevalence of cardiovascular disease but no evidence for an association with gaseous pollutants. We found strongly positive associations between particulate matter and cardiovascular disease in 2003 only, which highlights the importance of

    Objectives To assess the impact of initiatives aiming to increase clinician awareness of radiation exposure; to explore the challenges they face when communicating with patients; to study what they think is the most appropriate way of communicating the long-term potential risks of medical radiological exposure to patients. Design A quantitative and qualitative evaluation through a survey and focal groups. Setting San Juan Hospital and Dr Peset Hospital (Southeast Spain) and clinicians from Spanish scientific societies. Participants The surveys were answered (a) in person (216: all the radiologists (30), urologists (14) and surgeons (44) working at both participant hospitals; a sample of general practitioners from the catchment area of one hospital (45), and a consecutive sample of radiologists attending a scientific meeting (60)) or (b) electronically through Spanish scientific societies (299: radiologists (45), pneumologists (123), haematologists (75) and surgeons (40)). Clinicians were not randomly selected and thus the results are limited by the diligence of the individuals filling out the survey. Primary and secondary outcome measures Clinicians' knowledge and practices regarding medical radiological exposure, and what they considered most appropriate for communicating information to patients. Results Nearly 80% of the clinicians surveyed had never heard of the European recommendations. Fewer than 20% of the clinicians surveyed identified correctly the radiation equivalence dose of intravenous urography or barium enema. It was reported by 31.7% that they inform patients about the long-term potential risks of ionising radiation. All participants agreed that the most appropriate way to present information is a table with a list of imaging tests and their corresponding radiation equivalence dose in terms of chest X-rays and background radiation exposure. Conclusions Medical radiological exposure is frequently underestimated and rarely explained to patients. With a

    The Gemini Planet Imager Exoplanet Survey (GPIES) is targeting 600 young, nearby stars using the GPI instrument. We report here on recent results obtained with this instrument from our team.Rameau et al. (ApJL, 822 2, L2, 2016) presented astrometric monitoring of the young exoplanet HD 95086 b obtained with GPI between 2013 and 2016. Efficient Monte Carlo techniques place preliminary constraints on the orbital parameters of HD 95086 b. Under the assumption of a coplanar planet-disk system, the periastron of HD 95086 b is beyond 51 AU. Therefore, HD 95086 b cannot carve the entire gap inferred from the measured infrared excess in the SED of HD 95086. Additional photometric and spectroscopic measurements reported by de Rosa et al. (2016, apJ, in press) showed that the spectral energy distribution of HD 95086 b is best fit by low temperature (T~800-1300 K), low surface gravity spectra from models which simulate high photospheric dust content. Its temperature is typical to L/T transition objects, but the spectral type is poorly constrained. HD 95086 b is an important exoplanet to test our models of atmospheric properties of young extrasolar planets.Direct detections of debris disk are keys to infer the collisional past and understand the formation of planetary systems. Two debris disks were recently studied with GPI:- Draper et al. (submitted to ApJ, 2016) show the resolved circumstellar debris disk around HD 111520 at a projected range of ~30-100 AU using both total and polarized H-band intensity. Structures in the disks such as a large brightness asymmetry and symmetric polarization fraction are seen. Additional data would confirm if a large disruption event from a stellar fly-by or planetary perturbations altered the disk density- Esposito et al. (submitted to ApJ, 2016) combined Keck NIRC2 data taken at 1.2-2.3 microns and GPI 1.6 micron total intensity and polarized light detections that probes down to projected separations less than 10 AU to show that the HD

    In March 2011 the second largest accidental release of radioactivity in history occurred at the Fukushima Daiichi nuclear power plant following a magnitude 9.0 earthquake and subsequent tsunami. Teams from the U.S. Department of Energy, National Nuclear Security Administration Office of Emergency Response performed aerial surveys to provide initial maps of the dispersal of radioactive material in Japan. The initial results from the surveys did not report the concentration of 131I. This work reports on analyses performed on the initial survey data by a joint Japan-US collaboration to determine 131I ground concentration. This information is potentially useful in reconstruction of the inhalation and external exposure doses from this short-lived radionuclide. The deposited concentration of 134Cs is also reported.

  2. Adverse effects in adulthood resulting from low-level dioxin exposure in juvenile zebrafish.

    There is strong evidence indicating that disease in adult humans stems from a combination of genetic and environmental factors. A problem in identifying environmental factors is that subacute exposures during early life are often unnoticed, or exposures are variable among a diverse population. This leads to a confusing pattern in adulthood. An additional problem in following exposure effects in humans is the length of time needed to study outcomes spanning a human generation. We have recently developed a zebrafish model for studying the effects of sublethal juvenile exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD, dioxin). Although the initial exposure produces no effect at the time, we find skeletal and reproductive defects in adulthood and into subsequent generations. The short generation time of zebrafish along with the ability to maintain large cohorts of exposed individuals and their offspring allows us to overcome variation in exposure and genetic background. Here we describe progress in studying TCDD as an endocrine and developmental disruptor, and our results showing adult consequences of early exposure.

    The effects of two different sonic exposures on two vegetables, namely Chinese cabbage and cucumber at two growth stages, including seedlings and mature plants were investigated. The 3 h exposures included either 20 kHz sound waves or "green music" that comprised classic music and natural sounds such as those of birds, insects, water, etc. Analysis of variance between groups (ANOVA) was used to determine the appropriate statistics parameters for the different treatments. Both exposures caused significant elevations in the level of polyamines (PAs) and increased uptake of oxygen O(2) in comparison with the controls. For Chinese cabbage the highest PAs' levels were determined for both seedlings and mature plants that were exposed to "green music". The oxygen uptake in Chinese cabbage also increased as a result of sonic exposures, and the highest oxygen uptake was also observed after "green music" treatment. For cucumber, the highest content of PAs for both seedlings and mature cucumber plants was determined as a result of 20 kHz ultrasound exposure. 20 kHz exposure of mature plants also resulted in the highest level of oxygen uptake. No statistically significant differences in the vitamin C level were determined between the different sonic treatments and sham exposed vegetables.

    Full Text Available Abstract Background The National Comprehensive Cancer Network clinical practice guidelines in oncology-gastric cancer guidelines have been widely used to provide appropriate recommendations for the treatment of patients with gastric cancer. The aim of this study was to examine the adherence of surgical oncologists, medical oncologists, and radiation oncologists' to the recommended guidelines. Methods A questionnaire asking the treatment options for gastric cancer cases was sent to 394 Chinese oncology specialists, including surgical oncologists, medical oncologists, and radiation oncologists working in hospitals joined in The Western Cooperative Gastrointestinal Oncology Group of China. The questionnaire involved a series of clinical scenarios regarding the interpretation of surgery, neoadjuvant, adjuvant, and advanced treatment planning of gastric cancer. Results Analysis of 358 respondents (91% showed variations between each specialization and from the recommended guidelines in the management approaches to specific clinical scenarios. The majority of specialists admitted that less than 50% of patients received multidisciplinary evaluation before treatment. The participants gave different responses to questions involving adjuvant, neoadjuvant, and advanced settings, compared to the recommended guidelines. Conclusions These results highlight the heterogeneity of the treatment of gastric cancer. Surgical oncologists, medical oncologists, and radiation oncologists are not adhering to the recommended guidelines.

    WHAT IS KNOWN ON THE SUBJECT?: There is a developing body of research on violence in healthcare workplaces. Although psychiatric visiting nurses (PVNs) are an important group of professionals who provide medical services for people with mental disorders live in the community, little is known about the experiences and characteristics of violence exposure among PVNs, or the characteristics and work situations of PVNs related to violence exposure. WHAT THIS STUDY ADDS TO EXISTING KNOWLEDGE?: Approximately 40% of participants were exposed to violence during the previous 12 months; approximately 50% had been exposed during their PVN careers in PVN settings. The most frequent violence was verbal abuse. Longer career length as a PVN and greater number of visits per month were both positively associated with verbal abuse during the previous 12 months. Twenty-eight of the 34 participants (83%) who completed the IES-R-J survey had some residual psychological distress, and two (6%) had a potentially high risk of posttraumatic stress disorder. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: In devising policies and strategies against violence, PVN organizations and administrators should consider the characteristics of the violence, especially verbal abuse, as well as the characteristics and work situations of PVNs that are related to verbal abuse. Furthermore, they might provide relevant information on violence in PVN settings within their violence-prevention manuals or education. It would be important to provide support and to construct a safe workplace environment for PVNs who are experiencing residual psychological distress. Introduction Psychiatric visiting nurses (PVNs) play a crucial role by providing medical services for community-living individuals with mental disorders in Japan. However, little is known about violence towards PVNs. Aim This cross-sectional study investigated violence during visits and the resulting psychological effects for PVNs. Methods PVNs were assessed

    In a diary-survey study in 234 households with children aged 4-12 years, we investigated the associations between children's exposure to food advertising and their consumption of (a) advertised food brands, (b) advertised energy-dense food product categories, and (c) food products overall. Relations were examined using multiple hierarchical regression analysis, while controlling for various child (i.e., age, sex, television viewing time) and family variables (i.e., family income and consumption-related communication styles). Results showed that children's exposure to food advertising was significantly related to their consumption of advertised brands (beta=.21) and energy-dense product categories (beta=.19). The relation between advertising exposure and overall food consumption only held in lower-income families (beta=.19). In addition, consumption-related family communication was an important moderator of the relations between advertising and the food consumption variables. Socio-oriented family communication (i.e., striving for harmony and conformity) was particularly successful in reducing these relations. In conclusion, consistent with communication theories predicting spill-over effects of advertising, the impact of television food advertising exceeded the advertised brand and generalized to more generic unhealthy consumption patterns. Theoretical and societal consequences, as well as the important role of the family are discussed.

    What are the faintest distant galaxies we can see with the Hubble Space Telescope (HST) now, before the launch of the James Webb Space Telescope? This is the challenge taken up by the Frontier Fields, a Director’s discretionary time campaign with HST and the Spitzer Space Telescope to see deeper into the universe than ever before. The Frontier Fields combines the power of HST and Spitzer with the natural gravitational telescopes of massive high-magnification clusters of galaxies to produce the deepest observations of clusters and their lensed galaxies ever obtained. Six clusters—Abell 2744, MACSJ0416.1-2403, MACSJ0717.5+3745, MACSJ1149.5+2223, Abell S1063, and Abell 370—have been targeted by the HST ACS/WFC and WFC3/IR cameras with coordinated parallel fields for over 840 HST orbits. The parallel fields are the second-deepest observations thus far by HST with 5σ point-source depths of ∼29th ABmag. Galaxies behind the clusters experience typical magnification factors of a few, with small regions magnified by factors of 10–100. Therefore, the Frontier Field cluster HST images achieve intrinsic depths of ∼30–33 mag over very small volumes. Spitzer has obtained over 1000 hr of Director’s discretionary imaging of the Frontier Field cluster and parallels in IRAC 3.6 and 4.5 μm bands to 5σ point-source depths of ∼26.5, 26.0 ABmag. We demonstrate the exceptional sensitivity of the HST Frontier Field images to faint high-redshift galaxies, and review the initial results related to the primary science goals.

    Full Text Available Abstract Background Incense burning has been reported to adversely affect respiratory health. The aim of this study was to explore whether exposure to bakhour contributes to the prevalence of asthma and/or triggers its symptoms in Omani children by comparing two Omani regions with different prevalence of asthma. Methods A randomly selected sample of 10 years old schoolchildren were surveyed using an Arabic version of ISAAC Phase II questionnaires with the addition of questions concerning the use and effect of Arabian incense on asthma symptoms. Current asthma was defined as positive response to wheeze in the past 12 months or positive response to "ever had asthma" together with a positive response to exercise wheeze or night cough in the past 12 months. Simple and multivariable logistic regression analyses were performed to estimate the effect of bakhour exposure and other variables on current asthma diagnosis and parents' response to the question: "Does exposure to bakhour affect your child breathing?" Results Of the 2441 surveyed children, 15.4% had current asthma. Bakhour use more than twice a week was three times more likely to affect child breathing compared to no bakhour use (adjusted OR 3.01; 95% CI 2.23–4.08 and this effect was 2.55 times higher in asthmatics (adjusted OR 2.55; 95% CI 1.97–3.31 compared to non-asthmatics. In addition, bakhour caused worsening of wheeze in 38% of the asthmatics, making it the fourth most common trigger factor after dust (49.2%, weather (47.6% and respiratory tract infections (42.2%. However, there was no significant association between bakhour use and the prevalence of current asthma (adjusted OR 0.87; 95% CI 0.63–1.20. Conclusion Arabian incense burning is a common trigger of wheezing among asthmatic children in Oman. However, it is not associated with the prevalence asthma.

    Caspofungin is a member of the echinocandin class of antifungal agents that inhibit the synthesis of β 1,3 glucan thus disrupting fungal cell wall structure and function. Exposure of the Aspergillus fumigatus cultures to caspofungin (0.01, 0.1 or 1.0 μg/ml) resulted in a reduction in cell growth, but the production of the epipolythiodioxopiperazine toxin, gliotoxin, was comparable, or greater, in cultures exposed to caspofungin than untreated controls. Exposure of A. fumigatus hyphae to 1.0 μg/ml caspofungin for 4 h resulted in the release of amino acids (P = 0.01), protein (P = 0.002) and gliotoxin (P = 0.02). Cultures of A. fumigatus incubated in the presence of caspofungin for 4 or 24 h demonstrated enhanced gliotoxin release (P = 0.04 and 0.03, respectively) and biosynthesis (P = 0.04 and 0.03, respectively) compared to that by control cultures. The results presented here indicate that exposure of A. fumigatus to caspofungin results in increased cell permeability and an increase in the synthesis and release of gliotoxin. Since gliotoxin has well established immunosuppressive properties it is possible that exposure of A. fumigatus to caspofungin may potentiate the production of this toxin at the site of infection. Elevated gliotoxin biosynthesis may be an attempt by the fungus to restore the redox balance of the cell following exposure to the antifungal agent but the overall effect appears to be enhanced synthesis and release.

    Decreased expression of connexins has been associated with cancer, but the underlying mechanisms are poorly understood. We have previously shown that a 5 day exposure to hexachlorobenzene (HCB) resulted in decreased connexins expression in hepatocytes 45 days later, and that this down-regulation was linked to activation of Akt through the ILK pathway. Because HCB promotes cancer in both the liver and breast, the present study aimed to determine if the mechanisms are similar in both tissues. MCF-12A breast cells were thus transfected with vectors coding for either Akt or a constitutively active form of Akt. In those cells, activation of Akt was correlated with decreased Cx43 levels. Female rats were then exposed to HCB by gavage either following the same protocol used previously for the liver or through a chronic exposure. While no changes were observed after the 5 days exposure protocol, chronic exposure to HCB resulted in increased Akt levels and decreased Cx43 levels in breast cells. In vitro, Akt was activated in MCF-12A cells exposed to HCB either for 7 days or chronically, but no changes were observed in junctional proteins. Together, these results suggested that, while activation of Akt can decrease Cx43 expression in breast cells in vitro, other mechanisms are involved during HCB exposure, leading to a decrease in Cx43 levels in a model- and duration-dependent manner. Finally, we showed that HCB effects are tissue specific, as we did not observe the same results in breast and liver tissues.

  15. Potential radiological exposure rates resulting from hypothetical dome failure at Tank W-10

    Energy Technology Data Exchange (ETDEWEB)

    1994-07-01

    The main plant area at Oak Ridge National Laboratory (ORNL) contains 12 buried Gunite tanks that were used for the storage and transfer of liquid radioactive waste. Although the tanks are no longer in use, they are known to contain some residual contaminated sludges and liquids. In the event of an accidental tank dome failure, however unlikely, the liquids, sludges, and radioactive contaminants within the tank walls themselves could create radiation fields and result in above-background exposures to workers nearby. This Technical Memorandum documents a series of calculations to estimate potential radiological exposure rates and total exposures to workers in the event of a hypothetical collapse of a Gunite tank dome. Calculations were performed specifically for tank W-10 because it contains the largest radioactivity inventory (approximately half of the total activity) of all the Gunite tanks. These calculations focus only on external, direct gamma exposures for prescribed, hypothetical exposure scenarios and do not address other possible tank failure modes or routes of exposure. The calculations were performed with established, point-kernel gamma ray modeling codes.

    The aim of this paper is to present fibre exposure data recorded on the COLCHIC database. This database consolidates all occupational exposure data collected in French companies by the Caisses Régionales d'Assurance Maladie (regional health insurance funds, CRAM) and the Institut National de Recherche et de Sécurité (national institute for research and safety, INRS). A total of 8029 concentration results, expressed in number of fibres measured by phase-contrast optical microscopy, are available for exposure to asbestos fibres, ceramic fibres and man-made mineral fibres other than ceramic fibres. Presentation of base data by activity branch, activity sector or workplace permits identification of situations, for which prevention efforts are most essential. Analysis of exposure levels during the 1986-2004 period show that these are broadly influenced by changes in the exposure limit values. Wearing of respiratory protection equipment by employees is also discussed. The data may be helpful to occupational physicians performing occupational screening of exposed workers and to epidemiologists seeking information for building job-exposures matrices. In this respect, a database (FIBREX) will be available on the INRS web site (www.inrs.fr) at the beginning of 2007. This database will provide a higher level of detail in activity and workplace description than that which was possible for practical reasons in this paper.

    Increased cannabis potency has renewed concerns that secondhand exposure to cannabis smoke can produce positive drug tests. A systematic study was conducted of smoke exposure on drug-free participants. Six experienced cannabis users smoked cannabis cigarettes (5.3% THC in Session 1 and 11.3% THC in Sessions 2 and 3) in a sealed chamber. Six non-smokers were seated with smokers in an alternating manner. Sessions 1 and 2 were conducted with no ventilation and ventilation was employed in Session 3. Non-smoking participant specimens (collected 0–34 h) were analyzed with four immunoassays at different cutoff concentrations (20, 50, 75 and 100 ng/mL) and by GC-MS (LOQ = 0.75 ng/mL). No presumptive positives occurred for non-smokers at 100 and 75 ng/mL; a single positive occurred at 50 ng/mL; and multiple positives occurred at 20 ng/mL. Maximum THCCOOH concentrations by GC-MS for non-smokers ranged from 1.3 to 57.5 ng/mL. THCCOOH concentrations generally increased with THC potency, but room ventilation substantially reduced exposure levels. These results demonstrate that extreme cannabis smoke exposure can produce positive urine tests at commonly utilized cutoff concentrations. However, positive tests are likely to be rare, limited to the hours immediately post-exposure, and occur only under environmental circumstances where exposure is obvious. PMID:25326203

    It is well established that high ambient heat could cause congenital abnormalities resulting in miscarriage or stillbirth among certain species of mammals. However, this has not been systematically studied in real field settings among humans, despite the potential value of such knowledge for estimating the impact of global warming on the human species. This study sought to test the hypothesis that maternal heat exposure during pregnancy in hot regions is associated with increased prevalence of spontaneous abortions or stillbirths and to develop an analytical strategy to use existing data from maternal health surveys and existing data on historical heat levels at a geographic grid cell level. A subsample of the Ghana Maternal Health Survey 2007 was used in this study. This study sample consisted of 1136 women with pregnancy experiences between 2004 and 2007, out of which 141 women had a pregnancy that terminated in miscarriage or stillbirth. Induced-abortion cases were excluded. The linkage between ambient heat exposure and pregnancy outcome followed the epidemiological time-place-person principle, by linking timing of pregnancy outcome with historical data of local area heat levels for each month, as estimated in an international database. Maternal heat exposure level was estimated using calculated levels of the wet-bulb globe temperature (WBGT), which takes into account temperature, humidity, heat radiation, and air movement over the skin (wind speed). The values we used applied to exposure in the shade or in buildings without cooling (no solar heat radiation) and a standard air movement of 1 m/s. We applied two exposure durations: yearly average and monthly average for second month of pregnancy. In one analysis, we restricted the sample to four regions with time-homogeneous ambient heat. Analysis was made using logistic regression. About 12% of the latest pregnancies ended in either miscarriage (9.6%) or stillbirth (2.8%). The odds ratios indicated 12 to 15

    Full Text Available Objective - to compare results of spondylolisthesis treatment using different surgical technologies. Material and methods: 84 patients (aged from 19 till 67 with spondylolisthesis of 1-3 degree (H.W Meyerding were operated. Two methods of surgical exposures were used for decompression and stabilization. Anterior decompression and stabilization exposures from retroperitoneal access were used for the first group of patients. The second group was operated using posteriolateral interbody fusion with transpedicular screw fixation. The following results were estimated after operation: the level of patients’ postoperative adaptation period and the rate of neurological and orthopedic rehabilitation during the postoperative period. Conclusions. The obtained functional results show no difference for both groups where posterior and anterior exposures were used for spondylolisthesis surgical treatment of 1-3 degree.

    Persistent organic pollutants (POPs) are chemicals that accumulate in the food chain and are toxic to humans and wildlife. The fourth World Health Organization (WHO) survey on POP levels in human milk (2006-2009) aims to provide baseline and trend information on human exposure to POPs. So far Belgium participated in all three previous rounds (1988, 1992, 2001). Whereas the first three rounds focused on determination of dioxins and PCBs in pooled (mixed) samples, the fourth survey comprised the analyses of individual milk samples for nine "basic POPs" (chlorinated pesticides and indicator PCBs) and of pooled milk samples for "basic POPs", "advanced POPs" (dioxins and dioxin-like PCBs) and "optional POPs" (polybrominated diphenylethers [PBDEs], polybrominated dioxins and dibenzofurans [PBrDD/F], mixed halogenated dioxins and dibenzofurans [PXDD/F] and hexabromocyclododecane [HBCD]). For the Belgian participation human milk samples were collected during the summer of 2006 from 197 women between 18 and 30 years old distributed over all Belgian provinces. The individual samples were analyzed in a Belgian Laboratory for "basic" POPs. A pooled sample was made from 178 individual samples and analyzed by the WHO Reference Laboratory for the "basic, advanced and optional" POPs. The results indicate that most organochlorinated pesticides banned 25-30 years ago were below or around detection limits in Belgian human milk samples although DDE was still found at low levels in all samples. Over the last five years the levels of marker PCBs and PCDD/Fs in Belgian human milk decreased, respectively, by 58% and 39%. For some of the other emerging or older compounds recent international data are needed to allow comparison. This shows the importance of international studies as run by WHO.

Finally, JP-8 exposure did result in a significant depletion of total GSH that was observable in liver with a nonsignificant trend toward depletion in the brain and lung raising the possibility that the promotion of noise-induced hearing loss by JP-8 might have resulted from oxidative stress.

    Objective To investigate variations in quality of life at older ages we take a life course perspective to analyse long-term effects of physical working conditions upon quality of life after retirement. In doing so, we study to what extent these associations are explained by individuals’ health at older ages. Method We use administrative data and self-administered questionnaire responses from the French GAZEL cohort. Quality of life was assessed with CASP-19 in 2009 and related to three types of physical working conditions during previous working life: (1) ergonomic strain, (2) physical danger and (3) exposures to chemicals. Health was assessed in 2007 with the SF-36 Health Survey. Multiple regressions were calculated in retired men only, controlling for important confounders including social position. Results In contrast to men, few women were exposed to strenuous and dangerous working conditions in this cohort and were not included in subsequent analyses. Negative effects on retired men’s quality of life were found for the physical occupational exposures of ergonomic strain and physical danger, but not for chemical exposures. Effects were attenuated after the introduction of physical and mental health to the models, indicating an indirect effect of physical working conditions upon quality of life via health. Conclusion Adverse physical working conditions have long-term consequences for health and quality of life at older ages. Improvements to physical working conditions may improve individuals’ quality of life over the long term. PMID:23560563

    Background: Many international studies have been conducted to assess the knowledge, attitudes and practices (KAP) of the public toward sun exposure and sun-protection measures. However, there are scarce data on these factors from the Middle East. Objectives: This study aimed to explore the KAP of the public toward sun exposure and sun-protection measures among Saudis. Methods: A cross-sectional survey using a specially designed questionnaire was conducted on a stratified random sample of the general population in the five geographical regions of Saudi Arabia (central, eastern, northern, southern, and western). Data were collected between October 2010 and March 2011. Multiple logistic regressions were applied to relate the use of sunscreen and skin cancer awareness with various socio-demographic variables. Results: The questionnaire was distributed to 2900 Saudis. A total of 2622 questionnaires were completed, returned, and included in the data analysis, corresponding to a response rate of 90.4%. The mean (SD) age of respondents was 27.8 ± 9.7 years. Fifty percent (1301/1601) of the respondents were males. Fifty-five percent (1406/2544) were aware of the association between sun exposure and skin cancer. Female, young and student respondents were more likely to be aware of the connection between sun exposure and skin cancer (p Protective clothes were the most commonly used sun protection measure as reported by more than 90% of our participants. Conclusion: This study has shown that sun awareness and protection are generally inadequate in the Saudi population and suggests the need for health education programs.

    2017-01-01

    The exposure on the Chandra Deep Field-South (CDF-S) has recently been increased to 7 Ms, making it the most sensitive extragalactic X-ray survey by a wide margin. About 1050 X-ray sources have been detected, primarily distant active galactic nuclei (AGNs) and starburst/normal galaxies. The unmatched deep multiwavelength coverage for these sources allows superb follow-up investigations; e.g., 98.4% of the X-ray sources have multiwavelength counterparts, and 97.8% have spectroscopic/photometric redshifts. I will briefly describe the source catalog for the 7 Ms CDF-S and some exciting first science results. The latter will likely include (1) constraints on SMBH growth in the first galaxies as revealed by direct detection and stacking; (2) long-term variability studies of the AGNs producing most of cosmic accretion power; (3) AGN/galaxy interactions as investigated via the host properties of X-ray AGNs; and (4) measurements of the evolving X-ray binary populations of normal and starburst galaxies.

    Background: Ultraviolet irradiation by sun exposure has been associated with both harms and benefits to metabolic health. Objective: The objective of this study was to determine whether unprotected daily sun exposure is associated with the prevalence of diabetes and explore the underlying mechanism. Methods: We analyzed the Korean National Health and Nutrition Survey V from 2010 to 2011. Participants 19–60 years of age were asked about the average amount of time they had been exposed to direct sunlight per day since the age of 19. We categorized participants into three groups with different levels of lifetime daily sun exposure and explored the association of sun exposure with the prevalence of diabetes. Results: The risk of diabetes was higher in subjects with more than 5 h of unprotected sun exposure per day, with an odds ratio of 2.39 (95% CI 1.75–3.25), compared to those with less than 2 h of sun exposure, and the association remained significant after adjusting for diabetes risk factors. Long-term sun exposure was associated with increased central obesity and the possibility of an increase in visceral adiposity, especially among women, and with decrease in beta cell function and peripheral adiposity or percent body fat in men. Conclusions: Our study provides a cutoff for upper limit of sun exposure and suggests unprotected daily sun exposure for more than 5 h should be avoided to prevent diabetes. Increased central adiposity and decreased beta cell function were observed in women and men, respectively, who had long-term unprotected daily sun exposure. - Highlights: • Sun exposure for more than 5 h per day is associated with diabetes risk. • Insulin resistance associated with visceral adiposity may play a role in women. • Insulin secretory defect may explain diabetes risk in men.

  7. Field surveys of carbon monoxide in commercial settings using personal exposure monitors

    1984-02-01

    Miniaturized personal exposure monitors (PEMs) were employed to measure carbon monoxide (CO) in 588 different commercial settings (e.g., retail stores, office buildings, hotels, restaurants) in five California cities. Altogether, 5000 CO observations were made by recording the instantaneous instrument reading at 1-minute intervals as the investigators walked along sidewalks and into buildings. For 11 of 15 survey dates, two investigators walked side-by-side, permitting two adjacent PEMs to be compared. Quality assurance tests for 1706 pairs of values showed a very high degree of agreement. CO levels for indoor commercial settings were similar to those measured outdoors on sidewalks, apparently because the pollutant seeps into the structures from traffic outside. Although indoor levels usually were above 0 ppm, they seldom were above 9 ppm (the National Ambient Air Quality Standard for an 8-hour exposure), unless some indoor source could be identified. Carbon monoxide levels on outdoor streets did not vary greatly on different sides of the street, on corners and faces of blocks, and intersections.

    Clinical and research staff who work around magnetic resonance imaging (MRI) scanners are exposed to the static magnetic stray fields of these scanners. Although the past decade has seen strong developments in the assessment of occupational exposure to electromagnetic fields from MRI scanners, there is insufficient insight into the exposure variability that characterizes routine MRI work practice. However, this is an essential component of risk assessment and epidemiological studies. This paper describes the results of a measurement survey of shift-based personal exposure to static magnetic fields (SMF) (B) and motion-induced time-varying magnetic fields (dB/dt) among workers at 15 MRI facilities in the Netherlands. With the use of portable magnetic field dosimeters, >400 full-shift and partial shift exposure measurements were collected among various jobs involved in clinical and research MRI. Various full-shift exposure metrics for B and motion-induced dB/dt exposure were calculated from the measurements, including instantaneous peak exposure and time-weighted average (TWA) exposures. We found strong correlations between levels of static (B) and time-varying (dB/dt) exposure (r = 0.88-0.92) and between different metrics (i.e. peak exposure, TWA exposure) to express full-shift exposure (r = 0.69-0.78). On average, participants were exposed to MRI-related SMFs during only 3.7% of their work shift. Average and peak B and dB/dt exposure levels during the work inside the MRI scanner room were highest among technical staff, research staff, and radiographers. Average and peak B exposure levels were lowest among cleaners, while dB/dt levels were lowest among anaesthesiology staff. Although modest exposure variability between workplaces and occupations was observed, variation between individuals of the same occupation was substantial, especially among research staff. This relatively large variability between workers with the same job suggests that exposure classification

    2013-01-01

    In environmental remediation after nuclear accidents, radioactive wastes have to be appropriately managed in existing exposure situations with contamination resulting from the emission of radionuclides by such accidents. In this paper, a framework of radiation protection from radioactive waste management in existing exposure situations for application to the practical and reasonable waste management in contaminated areas, referring to related ICRP recommendations was proposed. In the proposed concept, intermediate reference levels for waste management are adopted gradually according to the progress of the reduction in the existing ambient dose in the environment on the basis of the principles of justification and optimisation by taking into account the practicability of the management of radioactive waste and environmental remediation. It is essential to include the participation of relevant stakeholders living in existing exposure situations in the selection of reference levels for the existing ambient dose and waste management.

    This report presents summary results of the 2010 ITS Deployment Tracking survey, the most recent survey conducted by the ITS Deployment Tracking Project. The U.S. Department of Transportation and its member agencies, including the Research and Innovative Technology Administration, have pursued a research and development agenda, the Intelligent Transportation System (ITS) Program, designed to integrate the latest in information technologies to improve the safety, mobility, and reliability of surface transportation modes. Within metropolitan areas, implementation of these advanced technologies has been accomplished by a variety of state and local transportation and emergency management agencies as well as the private sector. In order to measure the rate of ITS deployment within the nation s largest metropolitan areas, the ITS Deployment Tracking Project has conducted a nationwide survey of state and local transportation and emergency management agencies nearly every year since 1997. The results presented in this report are intended to be a summary of the entire database from the 2010 survey. Access to the complete survey results and previous national surveys are available on-line at http://www.itsdeployment.its.dot.gov. The website also provides access to survey results in the form of downloadable reports, including a survey summary for each survey type and fact sheets. Nearly 1,600 surveys were distributed to state and local transportation agencies in 2010. A total of seven (7) survey types were distributed including: Freeway Management, Arterial Management, Transit Management, Transportation Management Center (TMC), Electronic Toll Collection (ETC), Public Safety Law Enforcement, and Public Safety Fire/Rescue. Among other things, the data collection results indicate that ITS has moved from being experimental to mainstream and interest in continuing investments in ITS continues to be very strong. When asked about future deployment plans, one-third to three

    Linking accelerated laboratory test to field performance for predicting the service life of polymeric materials are being investigated at NIST using the reliability-based methodology. Based on this methodology, a successful linkage between the laboratory and field exposure data for a model polymeric material has been made. Recently, this methodology, for the first time, was introduced to the lifetime assessment of PV polymeric materials. In this paper, a mechanistic study of the degradation of three unstabilized model ethylene vinyl acetate (EVA) systems---uncured EVA, cured EVA and laminated EVA---was carried out under accelerated laboratory exposure and outdoor exposure. The NIST SPHERE (Simulated Photodegradation via High Energy Radiant Exposure) was used for the accelerated laboratory tests, and the outdoor exposure was conducted in Gaithersburg, Maryland. Simultaneous multiple stresses, including temperature, relative humidity and UV radiation, were applied individually or in combination during SPHERE exposure. The effects of the environmental factors on the main degradation mechanisms of different EVA systems were investigated. The results showed that the UV radiation was the most important factor for the degradation of EVA and a synergistic effect occurred between UV radiation and relative humidity. A slower degradation rate was observed for the laminated system as a result of limited diffusion of O2 and H2O into EVA. It was also found that the substantial chemical changes of the uncured EVA system did not yield yellowing, which was dramatically different from the peroxide cured EVA system. Additionally, the chemical degradation modes of the three EVA systems exposed outdoors appeared to be similar to those exposed to the SPHERE. The implication of this work to the current test standards was discussed.

    Studies examining effects of air pollutants often use single compounds, while real world' exposures are to more than one chemical. Thus, it is necessary to assess responses following inhalation of chemical mixtures. Rabbits were exposed for 3 hr to sulfuric acid aerosol at 0, 50, 75, or 125 micrograms/m3 in conjunction with ozone at 0, 0.1, 0.3, or 0.6 ppm, following which broncho-pulmonary lavage was performed. Various pulmonary response endpoints related to general cytotoxicity and macrophage function were examined. In addition, a goal of the study was to define an improved approach to the analysis of data sets involving binary pollutant mixtures. Results were evaluated using analysis of variance with multiple linear contrasts to determine the significance of any effect in the pollutant-exposed groups compared to sham control animals and to assess the type, and extent, of any toxicological interaction between acid and ozone. Interaction was considered to occur when the effects of combined exposure were either significantly greater or less than additive. Pollutant exposures had no effect on lavage fluid levels of lactate dehydrogenase, prostaglandins E2 and F2 alpha, nor on the numbers, viability, or types of immune cells recovered by lavage. Phagocytic activity of macrophages was depressed at the two highest acid levels and at all levels of ozone. Superoxide production by stimulated macrophages was depressed by acid exposure at the two highest concentrations, while ozone alone had no effect. Significant antagonistic interaction was observed following exposure to mixtures of 75 or 125 micrograms/m3 acid with 0.1 or 0.3 ppm ozone. The activity of tumor necrosis factor elicited from stimulated macrophages was depressed by acid at 75 and 125 micrograms/m3 while ozone had no effect. Exposure to mixtures of 125 micrograms/m3 acid with 0.3 or 0.6 ppm ozone resulted in synergistic interaction.

    To evaluate sun exposure behaviours, sun protection practices, general knowledge, attitudes and awareness of University students about the benefits of sun exposure and harmful effects of too much or avoidance of sun exposure. This cross-sectional survey study was conducted in December 2014 and January2015 at Prince Sattam bin Abdulaziz University, Al-Kharj, Saudi Arabia. A questionnaire consisting of multiple-choice closed questions was used. Sample was collected using cluster sampling method. SPSS 16 was used for data analysis. Of the 399 participants, 200(50.1%) were men and 199(49.9%) were women. The overall mean age was 21±1.82years (range: 18-30 years). Moreover, 217(54.4%) participants intentionally exposed themselves to sun. Spending summer holidays in coastal areas was reported by 150(37.6%). Sunglasses were used by 161(40.4%) participants. Besides, 274(68.7%) participants agreed that sun exposure of 5 to 10 minutes for two or three times per week was very important; 189(47.4%) were aware of the importance of sun exposure for child health. 165(66%), knew that too much sun exposure was harmful and might cause skin cancer. Most of the participants were aware of both beneficial effects of the appropriate sun exposure and harmful effects of too much exposure or its avoidance. However, proper sun exposure practices and sun protection practices need further guidance and encouragements from health-promoting programmes.

    Prenatal exposure to pesticides of three different classes initiated persistent postnatal endocrine dysfunction. Adrenal function and hepatic metabolism of corticosterone were studied in adult hybrid mice exposed during development to either an organophosphate (Diazinon), a carbamate (Carbofuran), or an organochlorine (Chlordane). Animals were exposed to relatively low levels of the toxins in utero and neonatally via the mothers' milk. Exposure to lower doses of the anticholinesterase compounds, Diazinon or Carbofuran, resulted in impairment of hepatic metabolism of corticosterone in vitro due to a loss in reductive capacity per unit liver weight. Plasma levels of corticosterone were also elevated in these animals, but without a concomitant increase in adrenal steroidogenesis in vitro. The effects of exposure to Chlordane were more complex. In male animals, exposure to lower doses of chlordane resulted in an increase in plasma corticosterone levels without an apparent increase in hepatic metabolism of corticosterone or adrenal steroidogenesis. In contrast, side-chain metabolism of corticosterone was decreased in female mice exposed to Chlordane. Similar effects on pituitary-adrenal function were not evident for the offspring of mice exposed to higher doses of the toxins. Possible mechanisms for this non-linear dose-response are discussed.

    Full Text Available Introduction The study aimed at measuring exhaled breath malondialdehyde (EBC-MDA in workers exposed to dust containing silica and at its comparison with the non-exposed control group. Material and methods The cross sectional, case-control study (N = 50 was performed in a tile and ceramics production factory in Yazd, Iran. EBC-MDA was quantified in exhaled breath of the participants by a lab made breath sampler. Exposure intensity was measured according to the NIOSH 0600 method in selected homogeneous exposure groups. Additionally, spirometry test was conducted to investigate a correlation between EBC-MDA and spirometric findings in the exposed workers. Results There was no difference in the observed exposure intensities of silica containing dust in different units. However, “coating preparation” was the unit with the highest concentration of dust. Although, the level of EBC-MDA in the cases was slightly higher than in the controls, the difference was not statistically significant (U = 252, p = 0.464. A significant and positive correlation was found between dust exposure intensity in working units and the measured EBC-MDA of workers (r = 0.467, N = 25, p = 0.027. There were also no statistically significant differences among job categories in the exposed group for the values of FEV1% (F(3, 44 = 0.656, p = 0.584, FVC% (F(3, 44 = 1.417, p = 0.172, and FEV1/FVC% (F(3, 44 = 1.929, p = 0.139. Conclusions The results showed a significant correlation between respirable dust exposure intensity and the level of EBC-MDA of the exposed subjects. However, our results did not show a significant correlation between lung function decreases and EBC-MDA.

    The purpose of the study was to report the prevalence of trauma exposure and PTSD, conditional risk of PTSD associated with each trauma exposure in the community population in Japan. An interview survey was conducted of a random sample of adult residents in 11 communities of Japan. Among 4134 respondents (response rate, 55%), data from those who completed the part 2 interview (n = 1682) were analyzed with a weight for this subsample. Lifetime experiences of 27 trauma events and PTSD were assessed using the WHO-Composite International Diagnostic Interview version 3.0. Sixty percent of the part 2 sample reported exposure to at least one lifetime traumatic event. Lifetime and 12-month PTSD prevalences were 1.3% and 0.7%, respectively. Percentage of all months lived with PTSD in the population was predominantly accounted for by physical/sexual assaults and having a child with serious illness, and unexpected death of loved one. Ten percent of respondents reported "private events", for which respondents did not have to describe the content, which accounted for 19% of months with PTSD. The lower prevalence of PTSD in Japan seems attributable to lower conditional risks of PTSD following these events, as well as different distributions of the events. The greater impact of events that occurred to loved ones rather than to oneself and "private events" on PTSD in Japan warrants further research of cross-cultural assessment of trauma exposure and cultural heterogeneity in the trauma-PTSD relationship.

    Many women of childbearing age are occupationally exposed to chemicals and concerned with the ensuing risk when pregnant. To present the results of a prospective follow-up study of 100 pregnant women and to discuss them after a brief overview of the published data on this topic. Since January 1996 the Lyon Poison Center has been conducting a prospective follow-up of all request concerning pregnant women occupationally exposed to chemicals. A thorough evaluation of the hazards of the handled products and of the actual exposure at the workplace is done for each patient. A toxicological advice is given and the outcome of the pregnancy is followed-up. One hundred pregnant women were included between January 1996 and December 2000. Based on the nature of the handled products, two groups have been identified: the first included 73 women exposed to organic solvents and the second 27 women exposed to miscellaneous. When the exposure was considered potentially hazardous for the pregnancy, either withdrawal from the workstation (19 cases), avoidance of certain activities (9 cases) or improvement of individual protective measures (29 cases) was recommended. In 43% of the cases, the occupational exposure was not considered hazardous to the outcome of the pregnancy. No increase of adverse outcome was identified: 4 miscarriages and 96 living births were observed, with 2 major malformations and 1 minor malformation. Occupational exposure to chemicals was not found to affect adversely the outcome of these 100 pregnancies.

    We aimed to observe the therapeutic effects of lithium on inhalational anesthetic sevoflurane-induced apoptosis in immature brain hippocampus. From postnatal day 5 (P5) to P28, male Sprague-Dawley pups were intraperitoneally injected with lithium chloride or 0.9 % sodium chloride. On P7 after the injection, pups were exposed to 2.3 % sevoflurane or air for 6 h. Brain tissues were harvested 12 h and 3 weeks after exposure. Cleaved caspase-3, nNOS protein, GSK-3β,p-GSK-3β were assessed by Western blot, and histopathological changes were assessed using Nissl stain and TUNEL stain. From P28, we used the eight-arm radial maze test and step-through test to evaluate the influence of sevoflurane exposure on the learning and memory of juvenile rats. The results showed that neonatal sevoflurane exposure induced caspase-3 activation and histopathological changes in hippocampus can be attenuated by lithium chloride. Sevoflurane increased GSK-3β activity while pretreatment of lithium decreased GSK-3β activity. Moreover, sevoflurane showed possibly slight but temporal influence on the spatial learning and the memory of juvenile rats, and chronic use of lithium chloride might have the therapeutic effect. Our current study suggests that lithium attenuates sevoflurane induced neonatal hippocampual damage by GSK-3β pathway and might improve learning and memory deficits in rats after neonatal exposure.

    2007-09-01

    Full Text Available Abstract Background Casino workers are exposed to high levels of secondhand smoke (SHS at work, yet remain at risk of being excluded from smoke-free legislation around the world. If the prime motivation for smoke-free legislation is the protection of workers, then a workforce experiencing ill-health associated with SHS exposure should not be excluded from legislation. This study aimed to determine the prevalence of respiratory and sensory irritation symptoms among a sample of casino workers, to identify any association between the reporting of symptoms and exposure to SHS at work, and to compare the prevalence of symptoms with that in other workers exposed to SHS. Methods A postal questionnaire survey of 1568 casino workers in London. Using multivariate analysis we identified predictors of respiratory and sensory irritation symptoms. Results 559 workers responded to the questionnaire (response of 36%. 91% of casino workers reported the presence of one or more sensory irritation symptoms in the previous four weeks, while the figure was 84% for respiratory symptoms. The presence of one or more sensory irritation symptoms was most strongly associated with reporting the highest exposure to SHS at work (OR 3.26; 1.72, 6.16. This was also true for reporting the presence of one or more respiratory irritation symptoms (OR 2.24; 1.34, 3.74. Prevalence of irritation symptoms in the casino workers was in general appreciably higher than that reported in studies of bar workers. Conclusion Our research supports the need for comprehensive smoke-free legislation around the world, covering all indoor workplaces including casinos.

    Bullying is a common exposure in high school and more recently cyberbullying has become prevalent among teens. We used the 2011 Arkansas Youth Risk Behavior Survey to estimate the prevalence of school bullying and cyberbullying and to measure its association with teen suicidality. In Arkansas, 11.6% of students reported only school bullying, 6.2% only cyberbullying, and 10.2% both forms of bullying. We determined "feeling unsafe at school" was a significant risk factor for depression and all suicide questions. We also found that being a victim of school bullying, cyberbullying, or both, increased the risk for depression, suicidal ideation, and plan.

    Free trade with animals and animal products requires transparency concerning health information of animal populations. On the basis of the bilateral agreement with the European Union (EU), Switzerland is obliged to document freedom from Aujeszky's disease (AD) in its pig population by conducting surveys on a regular basis. Such a survey was planned for the first time for the year 2001. In this context, it was evaluated whether additional pig diseases should be included in the survey. This article describes the evaluation procedure for the selection of pig diseases integrated in the survey 2001. Additionally, it reports and interprets the results of this survey. All of the 2537 farms and 41,719 blood samples were tested negative. Therefore, it could be documented with a confidence of 99.98% that the AD-prevalence in Switzerland is below 1%.

    Measurement methods for chemicals in biological and personal environmental samples have expanded rapidly and become a cornerstone of health studies and public health surveillance. These measurements raise questions about whether and how to report individual results to study participants, particularly when health effects and exposure reduction strategies are uncertain. In an era of greater public participation and open disclosure in science, researchers and institutional review boards (IRBs) need new guidance on changing norms and best practices. Drawing on the experiences of researchers, IRBs, and study participants, we discuss ethical frameworks, effective methods, and outcomes in studies that have reported personal results for a wide range of environmental chemicals. Belmont Report principles and community-based participatory research ethics imply responsibilities to report individual results, and several recent biomonitoring guidance documents call for individual reports. Meaningful report-back includes contextual information about health implications and exposure reduction strategies. Both narrative and graphs are helpful. Graphs comparing an individual's results with other participants in the study and benchmarks, such as the National Exposure Report, are helpful, but must be used carefully to avoid incorrect inferences that higher results are necessarily harmful or lower results are safe. Methods can be tailored for specific settings by involving participants and community members in planning. Participants and researchers who have participated in report-back identified benefits: increasing trust in science, retention in cohort studies, environmental health literacy, individual and community empowerment, and motivation to reduce exposures. Researchers as well as participants gained unexpected insights into the characteristics and sources of environmental contamination. Participants are almost universally eager to receive their results and do not regret getting

    The National Wildlife Refuge System (Refuge System), established in 1903 and managed by the U.S. Fish and Wildlife Service (Service), is the leading network of protected lands and waters in the world dedicated to the conservation of fish, wildlife and their habitats. There are 556 national wildlife refuges and 38 wetland management districts nationwide, encompassing more than 150 million acres. The Refuge System attracts more than 45 million visitors annually, including 25 million people per year to observe and photograph wildlife, over 9 million to hunt and fish, and more than 10 million to participate in educational and interpretation programs. Understanding visitors and characterizing their experiences on national wildlife refuges are critical elements of managing these lands and meeting the goals of the Refuge System. The Service collaborated with the U.S. Geological Survey to conduct a national survey of visitors regarding their experiences on national wildlife refuges. The survey was conducted to better understand visitor needs and experiences and to design programs and facilities that respond to those needs. The survey results will inform Service performance planning, budget, and communications goals. Results will also inform Comprehensive Conservation Plan (CCPs), Visitor Services, and Transportation Planning processes. This data series consists of 53 separate data files. Each file describes the results of the survey for an individual refuge and contains the following information: * Introduction: An overview of the Refuge System and the goals of the national surveying effort. * Methods: The procedures for the national surveying effort, including selecting refuges, developing the survey instrument, contacting visitors, and guidance for interpreting the results. * Refuge Description: A brief description of the refuge location, acreage, purpose, recreational activities, and visitation statistics, including a map (where available) and refuge website link

    Epidemiological studies have examined the relative importance of Traumatic Events (TEs) in accounting for the societal burden of post-traumatic stress disorder (PTSD). However, most studies used the worst trauma experienced, which can lead to an overestimation of the conditional risk of PTSD. Although a number of epidemiological surveys on PTSD have been carried out in the United States, only a few studies in limited sample have been conducted in Italy. This study, carried out in the framework of the World Mental Health Survey Initiative, is a cross-sectional household survey of a representative sample of the Italian adult population. Lifetime prevalence of TEs and 12-month prevalence of PTSD were evaluated using the Composite International Diagnostic Interview (CIDI). Reports of PTSD associated with randomly selected TEs were weighted by the individual-level probabilities of TE selection to generate estimates of population-level PTSD risk associated with each TE. Network events was the most commonly reported class of TEs (29.4%). War events had the highest conditional risk of PTSD (12.2%). The TEs that contributed most to societal PTSD burden were unexpected death of a loved one (24.1%) and having seen atrocities (18.2%). Being female was related to high risk of PTSD after experiencing a TE. Exposure to network events is commonly reported among Italian adults, but two TEs are responsible for the highest burden associated with PTSD: the unexpected death of someone close and sexual assault. These results can help designing public health interventions to reduce the societal PTSD burden.

    In rhesus macaques, previous studies have shown that episodic exposure to allergen alone or combined with ozone inhalation during the first 6 months of life results in a condition with many of the hallmarks of asthma. This exposure regimen results in altered development of the distal airways and parenchyma (Avdalovic et al., 2012). We hypothesized that the observed alterations in the lung parenchyma would be permanent following a long-term recovery in filtered air (FA) housing. Forty-eight infant rhesus macaques (30 days old) sensitized to house dust mite (HDM) were treated with two week cycles of FA, house dust mite allergen (HDMA), ozone (O{sub 3}) or HDMA/ozone (HDMA + O{sub 3}) for five months. At the end of the five months, six animals from each group were necropsied. The other six animals in each group were allowed to recover in FA for 30 more months at which time they were necropsied. Design-based stereology was used to estimate volumes of lung components, number of alveoli, size of alveoli, distribution of alveolar volumes, interalveolar capillary density. After 30 months of recovery, monkeys exposed to HDMA, in either group, had significantly more alveoli than filtered air. These alveoli also had higher capillary densities as compared with FA controls. These results indicate that early life exposure to HDMA alone or HDMA + O{sub 3} alters the development process in the lung alveoli. - Highlights: • Abnormal lung development after postnatal exposure to ozone and allergen • This remodeling is shown as smaller, more numerous alveoli and narrower airways. • Allergen appears to have more of an effect than ozone during recovery. • These animals also have continued airway hyperresponsiveness (Moore et al. 2014)

    Full Text Available Abstract Background Health-related data at local level could be provided by supplementing national health surveys with local boosts. Self-completion surveys are less costly than interviews, enabling larger samples to be achieved for a given cost. However, even when the same questions are asked with the same wording, responses to survey questions may vary by mode of data collection. These measurement differences need to be investigated further. Methods The Health Survey for England in London ('Core' and a London Boost survey ('Boost' used identical sampling strategies but different modes of data collection. Some data were collected by face-to-face interview in the Core and by self-completion in the Boost; other data were collected by self-completion questionnaire in both, but the context differed. Results were compared by mode of data collection using two approaches. The first examined differences in results that remained after adjusting the samples for differences in response. The second compared results after using propensity score matching to reduce any differences in sample composition. Results There were no significant differences between the two samples for prevalence of some variables including long-term illness, limiting long-term illness, current rates of smoking, whether participants drank alcohol, and how often they usually drank. However, there were a number of differences, some quite large, between some key measures including: general health, GHQ12 score, portions of fruit and vegetables consumed, levels of physical activity, and, to a lesser extent, smoking consumption, the number of alcohol units reported consumed on the heaviest day of drinking in the last week and perceived social support (among women only. Conclusion Survey mode and context can both affect the responses given. The effect is largest for complex question modules but was also seen for identical self-completion questions.

    Full Text Available Understanding the short- and long-term impacts of a biomonitoring and exposure project and reporting personal results back to study participants is critical for guiding future efforts, especially in the context of environmental justice. The purpose of this study was to evaluate learning outcomes from environmental communication efforts and whether environmental health literacy goals were met in an environmental justice community. We conducted 14 interviews with parents who had participated in the University of Arizona’s Metals Exposure Study in Homes and analyzed their responses using NVivo, a qualitative data management and analysis program. Key findings were that participants used the data to cope with their challenging circumstances, the majority of participants described changing their families’ household behaviors, and participants reported specific interventions to reduce family exposures. The strength of this study is that it provides insight into what people learn and gain from such results communication efforts, what participants want to know, and what type of additional information participants need to advance their environmental health literacy. This information can help improve future report back efforts and advance environmental health and justice.

    We report constraints on spin-independent weakly interacting massive particle (WIMP)-nucleon scattering using a 3.35 ×1 04 kg day exposure of the Large Underground Xenon (LUX) experiment. A dual-phase xenon time projection chamber with 250 kg of active mass is operated at the Sanford Underground Research Facility under Lead, South Dakota (USA). With roughly fourfold improvement in sensitivity for high WIMP masses relative to our previous results, this search yields no evidence of WIMP nuclear recoils. At a WIMP mass of 50 GeV c-2 , WIMP-nucleon spin-independent cross sections above 2.2 ×10-46 cm2 are excluded at the 90% confidence level. When combined with the previously reported LUX exposure, this exclusion strengthens to 1.1 ×10-46 cm2 at 50 GeV c-2 .

    Private wells in the United States are unregulated for drinking water standards and are the homeowner’s responsibility to test and treat. Testing for water quality parameters such as arsenic (As) is a crucial first step for homeowners to take protective actions. This study seeks to identify key behavioral factors influencing homeowners’ decisions to take action after receiving well As test results. A January 2013 survey of central Maine households (n=386, 73% response) who were notified 3–7 years earlier that their well water contained As above 10 μg/L found that 43% of households report installing As treatment systems. Another 30% report taking other mitigation actions such as drinking bottled water because of the As, but the remaining 27% of households did not act. Well water As level appears to be a motivation for mitigation: 31% of households with well water level between 10 and 50 μg/L did not act, compared to 13% of households with well water > 50 μg/L. Belief that the untreated water is not safe to drink (risk) and that reducing drinking water As would increase home value (instrumental attitude) were identified as significant predictors of mitigating As. Mitigating As exposure is associated with less worry about the As level (affective attitude), possibly because those acting to reduce exposure feel less worried about As. Use of a treatment system specifically was significantly predicted by confidence that one can maintain a treatment system, even if there are additional costs (self-efficacy). An assessment of As treatment systems used by 68 of these households with well water As >10 μg/L followed up with in August-November 2013 found that 15% of treatment units failed to produce water below As 10 μg/L, suggesting there are continued risks for exposure even after the decision is made to treat.

    This study estimated in 7 Italian cities the prevalence of prenatal exposure to ethanol by determining fatty acid ethyl esters (FAEEs; palmitic, palmitoleic, stearic, oleic, linoleic, linolenic, and arachidonic esters) and ethyl glucuronide (EtG) in neonatal meconium samples. A total of 607 meconium samples were obtained from neonatal wards of 7 public hospitals: Verona and San Daniele del Friuli in the northeast of the country, Reggio Emilia in the middle east, Florence and Rome in the center, and Naples and Crotone in the southwest of the peninsula. Meconium biomarkers were assessed by a validated methodology using liquid chromatography-tandem mass spectrometry and the results categorized using the accepted cutoff of 2 nmol/g total amount of 7 FAEEs and 2 nmol/g EtG, to differentiate between heavy maternal ethanol use during pregnancy and occasional or no use at all. On the basis of the above-reported cutoffs, the overall prevalence of newborns prenatally exposed to maternal ethanol was 7.9%: 0% in Verona, 4.0% in San Daniele del Friuli, 4.9% in Naples, 5.0% in Florence, 6.2% in Crotone, up to 10.6% in Reggio Emilia, and 29.4% in Rome. Low maternal education level and younger maternal age were associated with biomarker scores over the cutoff. There was also a significant correlation between the highest percentage of prenatal exposure in the capital and certain maternal sociodemographic characteristics. These results indicate considerable variability in the prevalence of fetal exposure to ethanol in different Italian cities, as determined by the objective measurement of biomarkers in meconium. These data, together with previous ones obtained in Barcelona, Spain, indicate that gestational ethanol exposure is widespread, at least in parts of Europe.

    To investigate cigarette smoking prevalence and exposure to various forms of cigarette marketing among students in 10 African countries. We used data collected during 2009-2011 from the Global Youth Tobacco Survey (GYTS), a school-based cross-sectional survey of students aged 13-15years, to measure the prevalence of cigarette smoking and exposure to cigarette marketing; comparisons to estimates from 2005 to 2006 were conducted for five countries where data were available. Current cigarette smoking ranged from 3.4% to 13.6% among students aged 13-15 in the 10 countries studied, although use of tobacco products other than cigarettes was more prevalent in all countries except in Cote D'Ivoire. Cigarette smoking was higher among boys than girls in seven out of the 10 countries. Among the five countries with two rounds of surveys, a significant decrease in cigarette smoking prevalence was observed in Mauritania and Niger; these two countries also experienced a decline in three measures of cigarette marketing exposure. It is also possible that smoking prevalence might have risen faster among girls than boys. Cigarette smoking among youth was noticeable in 10 African countries evaluated, with the prevalence over 10% in Cote D'Ivoire, Mauritania, and South Africa. Cigarette marketing exposure varied by the types of marketing; traditional venues such as TV, outdoor billboards, newspapers, and magazines were still prominent. Published by Elsevier Inc.

    Full Text Available Abstract Background Human beings from time immemorial have eradicated neighbouring tribes, languages, religions, and cultures. In war and crisis, the cumulative exposure to traumatic stress constitutes a predictor of the development of post traumatic stress disorder (PTSD. However, homicide has evolved as a profitable strategy in man, leading to greater reproductive success. Thus, an evolutionary advantage of perpetrating violence would be eliminated if the exposure to aggressive acts would traumatize the perpetrator. We argue that perpetrating violence could actually ‘immunize’ a person against adverse effects of traumatic stressors, significantly reducing the risk of developing PTSD. Methods We surveyed 42 former child soldiers in Northern Uganda that have all been abducted by the Lord Resistance Army (LRA as well as 41 non-abducted controls. Results Linear regression analyses revealed a dose–response effect between the exposure to traumatic events and the Posttraumatic Diagnostic Scale (PDS sum score. However, the vulnerability to develop trauma related symptoms was reduced in those with higher scores on the Appetitive Aggression Scale (AAS. This effect was more pronounced in the formerly abducted group. Conclusions We conclude that attraction to aggression when being exposed to the victim’s struggling can lead to a substantial risk-reduction for developing PTSD.

    Conclusions: The ACA will affect all specialties, including plastic surgery. The results of this survey suggest that many plastic surgeons believe that they have a baseline understanding of current health-care reform. The majority of surveyed surgeons do not support the Act. It is imperative that plastic surgeons possess the knowledge of the ACA; its changes, both current and impending, will likely affect patient mix, coverage of procedures, and reimbursement.

    Concentrations of CPY in surface waters are an integral determinant of risk to aquatic organisms. CPY has been measured in surface waters of the U.S. in several environmental monitoring programs and these data were evaluated to characterize concentrations, in relation to major areas of use and changes to the label since 2001, particularly the removal of domestic uses. Frequencies of detection and 95th centile concentrations of CPY decreased more than fivefold between 1992 and 2010. Detections in 1992-2001 ranged from 10.2 to 53%, while 2002-2010 detections ranged from 7 to 11%. The 95th centile concentrations ranged from 0.007 to 0.056 j.lg L -I in 1992-2001 and 0.006-0.008 j.lg L -I in 2002-2010.The greatest frequency of detections occurred in samples from undeveloped and agricultural land-use classes. Samples from urban and mixed land-use classes had the smallest frequency of detections and 95th centile concentrations, consistent with the cessation of most homeowner uses in 2001. The active metabolite of CPY, CPYO, was not detected frequently or in large concentrations. In 10,375 analyses from several sampling programs conducted between 1999 and 2012, only 25 detections (0.24% of samples) of CPYO were reported and estimated concentrations were less than the LOQ.Although the monitoring data on CPY provide relevant insight in quantifying the range of concentrations in surface waters, few monitoring programs have sampled at a frequency sufficient to quantify the time-series pattern of exposure. Therefore,numerical simulations were used to characterize concentrations of CPY in water and sediment for three representative high exposure environments in the U.S. Thefate of CPY in the environment is dependent on a number of dissipation and degradation processes. In terms of surface waters, fate in soils is a major driver of the potential for runoff into surface waters and results from a number of dissipation studies in the laboratory were characterized.

    Full Text Available Background: Many international studies have been conducted to assess the knowledge, attitudes and practices (KAP of the public toward sun exposure and sun-protection measures. However, there are scarce data on these factors from the Middle East. Objectives: This study aimed to explore the KAP of the public toward sun exposure and sun-protection measures among Saudis. Methods: A cross-sectional survey using a specially designed questionnaire was conducted on a stratified random sample of the general population in the five geographical regions of Saudi Arabia (central, eastern, northern, southern, and western. Data were collected between October 2010 and March 2011. Multiple logistic regressions were applied to relate the use of sunscreen and skin cancer awareness with various socio-demographic variables. Results: The questionnaire was distributed to 2900 Saudis. A total of 2622 questionnaires were completed, returned, and included in the data analysis, corresponding to a response rate of 90.4%. The mean (SD age of respondents was 27.8 ± 9.7 years. Fifty percent (1301/1601 of the respondents were males. Fifty-five percent (1406/2544 were aware of the association between sun exposure and skin cancer. Female, young and student respondents were more likely to be aware of the connection between sun exposure and skin cancer (p < 0.001. Likewise, respondents from the middle social class and those with higher education levels were more likely to be informed (p < 0.02. The prevalence of regular sunscreen use among study participants was only 23.7%, and female and employed respondents were more likely to use sunscreen (p < 0.001. Protective clothes were the most commonly used sun protection measure as reported by more than 90% of our participants. Conclusion: This study has shown that sun awareness and protection are generally inadequate in the Saudi population and suggests the need for health education programs.

    In recent years increasing interest in the issue of treatment personalization for type 2 diabetes (T2DM) has emerged. This international web-based survey aimed to evaluate opinions of physicians about tailored therapeutic algorithms developed by the Italian Association of Diabetologists (AMD) and available online, and to get suggestions for future developments. Another aim of this initiative was to assess whether the online advertising and the survey would have increased the global visibility of the AMD algorithms. The web-based survey, which comprised five questions, has been available from the homepage of the web-version of the journal Diabetes Care throughout the month of December 2013, and on the AMD website between December 2013 and September 2014. Participation was totally free and responders were anonymous. Overall, 452 physicians (M=58.4%) participated in the survey. Diabetologists accounted for 76.8% of responders. The results of the survey show wide agreement (>90%) by participants on the utility of the algorithms proposed, even if they do not cover all possible needs of patients with T2DM for a personalized therapeutic approach. In the online survey period and in the months after its conclusion, a relevant and durable increase in the number of unique users who visited the websites was registered, compared to the period preceding the survey. Patients with T2DM are heterogeneous, and there is interest toward accessible and easy to use personalized therapeutic algorithms. Responders opinions probably reflect the peculiar organization of diabetes care in each country.

    Aim: To investigate the effects of prenatal exposure to lipopolysacchadde (LPS) on blood pressure and body weight of offspring in rats. Methods: Sixteen healthy,pregnant rats were randomly divided into 2 groups. The rats in the LPS group were injected intraperitoneally with LPS (0.79 mg/kg) on the d 8, d 10, and d 12 of gestation. Those in the control group were only treated with normal saline. After delivery, all offspring were weighed and blood pressure was measured by the tail-cuff method once every 2 weeks from the 6th to the 24th week. In the 15th week,their food intake was weighed every day. At the end of the 24th week, the rats were killed by decapitation. Abdominal adipose tissues were weighed, and the serum level of leptin was detected by radioimmunoassay. Results: The offspring with prenatal LPS exposure showed increased systemic arterial pressure, heavier body weight, elevated food intake, increased adipose tissue weight, and increased circulating leptin compared with the controls. Conclusion: Prenatal exposure to LPS leads to increases in blood pressure and body weight in rats.

    Ethyl tertiary butyl ether (ETBE) is biofuel additive recently used in Japan and some other countries. Limited evidence shows that ETBE has low toxicity. Acetaldehyde (AA), however, as one primary metabolite of ETBE, is clearly genotoxic and has been considered to be a potential carcinogen. The aim of this study was to evaluate the effects of ALDH2 gene on ETBE-induced genotoxicity and metabolism of its metabolites after inhalation exposure to ETBE. A group of wild-type (WT) and Aldh2 knockout (KO) C57BL/6 mice were exposed to 500ppm ETBE for 1-6h, and the blood concentrations of ETBE metabolites, including AA, tert-butyl alcohol and 2-methyl-1,2-propanediol, were measured. Another group of mice of WT and KO were exposed to 0, 500, 1750, or 5000ppm ETBE for 6h/day with 5 days per weeks for 13 weeks. Genotoxic effects of ETBE in these mice were measured by the alkaline comet assay, 8-hydroxyguanine DNA-glycosylase modified comet assay and micronucleus test. With short-term exposure to ETBE, the blood concentrations of all the three metabolites in KO mice were significantly higher than the corresponding concentrations of those in WT mice of both sexes. After subchronic exposure to ETBE, there was significant increase in DNA damage in a dose-dependent manner in KO male mice, while only 5000ppm exposure significantly increased DNA damage in male WT mice. Overall, there was a significant sex difference in genetic damage in both genetic types of mice. These results showed that ALDH2 is involved in the detoxification of ETBE and lack of enzyme activity may greatly increase the sensitivity to the genotoxic effects of ETBE, and male mice were more sensitive than females.

    This report contains the results of a limited series of measurements at the Lake Ontario Ordnance Works site, three miles northeast of Lewiston, New York. The scope of this survey was not extensive, and the survey was conducted to support a concurrent aerial survey conducted by EG and G, Inc. Results of this survey indicate two souces of significant external gamma exposure on the site as well as several locations that retain low to intermediate levels of radioactivity in soil. Off-site soil radionuclide concentrations were well within background levels with one exception. Water radionuclide concentrations on the site in the Central Drainage Ditch are significantly above background levels but decrease with distance from the spoil pile, and are within restrictive concentration guides for off-site locations.

    Details are presented of the HI Jodrell All Sky Survey (HIJASS). HIJASS is a blind neutral hydrogen (HI) survey of the northern sky, being conducted using the multibeam receiver on the Lovell Telescope at Jodrell Bank. HIJASS covers the velocity range -3500 km/s to 10000 km/s with a velocity resolution of 18.1 km/s and a spatial positional accuracy of ~2.5 arcmin. Thus far about 1115 sq deg have been surveyed. We describe the methods of detecting galaxies within the HIJASS data and of measuring their HI parameters. The properties of the resulting HI-selected sample of galaxies are described. Of the 222 sources so far confirmed, 170 (77 per cent) are clearly associated with a previously catalogued galaxy. A further 23 sources (10 percent) lie close (within 6 arcmin) to a previously catalogued galaxy for which no previous redshift exists. A further 29 sources (13 per cent) do not appear to be associated with any previously catalogued galaxy. The distributions of peak flux, integrated flux, HI mass and cz are di...

    We describe a new mm-wave molecular-line mapping survey of the southern Galactic Plane and its first data releases. The Three-mm Ultimate Mopra Milky Way Survey (ThrUMMS) maps a 60{\\deg}x2{\\deg} sector of our Galaxy's fourth quadrant, using a combination of fast mapping techniques with the Mopra radio telescope, simultaneously in the J=1-0 lines of $^{12}$CO, $^{13}$CO, C$^{18}$O, and CN near 112 GHz at ~arcminute and ~0.3 km s$^{-1}$ resolution, with ~2 K channel$^{-1}$ sensitivity for $^{12}$CO and ~1 K channel$^{-1}$ for the other transitions. The calibrated data cubes from these observations are made available to the community after processing through our pipeline. Here, we describe the motivation for ThrUMMS, the development of new observing techniques for Mopra, and how these techniques were optimised to the objectives of the survey. We showcase some sample data products and describe the first science results on CO-isotopologue line ratios. These vary dramatically across the Galactic Plane, indicating a...

    We performed a laboratory analysis of spices sold in Sri Lanka for lead content. Samples of curry powder, chili powder and turmeric powder from seven provinces, collected using the market basket survey method, underwent atomic absorption spectrometry. Blanks and standards were utilised for instrument calibration and measurement accuracy. The results were validated in two different laboratories. All samples were found to have lead levels below the US Food and Drug Administration's action level of 0.5 μg/g. Spices sold in Sri Lanka contain lead concentrations that are low and within the stipulated safety standards.

    Full Text Available Objective: Exposure to Second Hand Smoke (SHS has been associated with an increased risk of respiratory symptoms, upper and lower respiratory tract diseases and an increased risk of asthma and chronic obstructive pulmonary disease. The majority of cases of mortality and morbidity is attributable to exposure of adults to SHS and is related to cardiovascular diseases and lung cancer. In Egypt, comprehensive smoke-free laws exist, however, in many workplaces they are poorly enforced consequently exposing workers to the detrimental health hazards of SHS. We aimed at determination of workplace exposure to Second Hand Smoke (SHS and its association with respiratory and sensory irritation symptoms in hospital workers in Port-said governorate in Egypt. Material and methods: A cross-sectional face to face survey was conducted by the use of a standardised questionnaire among 415 adult hospital workers; representing 50% of all employees (81% response rate; recruited from 4 randomly selected general hospitals in Port-said governorate in Egypt. Results: All hospitals employees reported exposure to SHS - on average 1.5 (SD = 2.5 hours of exposure per day. After controlling for potential confounders, exposure to SHS at work was significantly associated with an increased risk of wheezes (OR = 1.14, p < 0.01, shortness of breath (OR = 1.17, p < 0.01, phlegm (OR = 1.23, p < 0.01, running and irritated nose (OR = 1.14, p < 0.01 as well as a sore, scratchy throat (OR = 1.23. Conclusions: These findings point out that workplace exposure to SHS is evident in hospitals in Port-said governorate and that workers are adversely affected by exposure to it at work. This underlines the importance of rigorous enforcement of smoke-free policies to protect the workers' health in Egypt.

    Full Text Available This study asked two broad questions: (1 what is the prevalence of teen pregnancy in contemporary Vietnam; and (2 what selected social, family, and individual factors are associated with teen pregnancy in Vietnam? The study utilized Vietnam Survey Assessment of Vietnamese Youth surveys conducted in 2003 and 2008 to answer the two research questions within the context of fast political, economic, and social change in Vietnam in the last two decades. Results of this study show that the prevalence of pregnancy among Vietnamese teenagers in the surveys was stable at 4%, or 40 pregnancies per 1000 adolescent girls aged 14 to 19. Age, experience of domestic violence, and early sexual debut were positively correlated with higher odds of teenage pregnancy for both survey cohorts; however, being an ethnic minority, educational attainment, sexual education at school, Internet use, and depressive symptoms were significantly related to teenage pregnancy only in the 2008 cohort.

    Exposure to secondhand smoke (SHS) from burning tobacco products causes disease and premature death among non-smoking adults and children. The objective of this study was to determine the nature, extent and demographic correlates of SHS exposure among adults in low- and middle-income countries with a high burden of tobacco use. Data were obtained from the Global Adult Tobacco Survey (GATS), a nationally representative household survey of individuals 15 years of age or older. Interviews were conducted during 2008-2010 in Bangladesh, Brazil, China, Egypt, India, Mexico, the Philippines, Poland, Russia, Thailand, Turkey, Ukraine, Uruguay and Vietnam. Descriptive statistics were used to determine the prevalence and correlates of SHS exposure in homes, workplaces, government buildings, restaurants, public transportation and healthcare facilities. Exposure to SHS in the home ranged from 17.3% (Mexico) to 73.1% (Vietnam). Among those who work in an indoor area outside the home, SHS exposure in the workplace ranged from 16.5% (Uruguay) to 63.3% (China). Exposure to SHS ranged from 6.9% (Uruguay) to 72.7% (Egypt) in government buildings, 4.4% (Uruguay) to 88.5% (China) in restaurants, 5.4% (Uruguay) to 79.6% (Egypt) on public transportation, and 3.8% (Uruguay) to 49.2% (Egypt) in healthcare facilities. A large proportion of adults living in low- and middle-income countries are exposed to SHS in their homes, workplaces, and other public places. Countries can enact and enforce legislation requiring 100% smoke-free public places and workplaces, and can also conduct educational initiatives to reduce SHS exposure in homes.

    2002-01-01

    In frame of a research project undertaken in collaboration with Polish airlines LOT, analysis of aircrews exposure to cosmic radiation has been performed. The applied methods included measurements of radiation doses with thermoluminescent detectors (MTS-N, MCP-N) and track detectors (CR-39) and also calculations of route doses with the CARI computer code. The obtained results indicate that aircrews of nearly all airplanes, with exception of these flying only on ATR aircraft, exceed regularly or may exceed in some conditions, effective doses of 1 mSv. In case of Boeing-767 aircrews such exceeding occurs always, independently of solar activity. Investigations revealed, that during these periods of the solar cycle, when intensity of cosmic radiation is high, exceeding of 6 mSv level is also possible. These results indicate, that according to Polish and European regulations it is necessary for airlines to provide regular estimations of radiation exposure of aircrews. Basing on the obtained results a system for pe...

    Full Text Available Abstract Background Little is known about long-term adverse health consequences experienced by flight attendants exposed to secondhand smoke (SHS during the time smoking was allowed on airplanes. We undertook this study to evaluate the association between accumulated flight time in smoky airplane cabins and respiratory tract diseases in a cohort of never smoking flight attendants. Methods We conducted a mailed survey in a cohort of flight attendants. Of 15,000 mailed questionnaires, 2053 (14% were completed and returned. We excluded respondents with a personal history of smoking (n = 748 and non smokers with a history of respiratory tract diseases before the age of 18 years (n = 298. The remaining 1007 respondents form the study sample. Results The overall study sample was predominantly white (86% and female (89%, with a mean age of 54 years. Overall, 69.7% of the respondents were diagnosed with at least one respiratory tract disease. Among these respondents, 43.4% reported a diagnosis of sinusitis, 40.3% allergies, 30.8% bronchitis, 23.2% middle ear infections, 13.6% asthma, 13.4% hay fever, 12.5% pneumonia, and 2.0% chronic obstructive pulmonary disease. More hours in a smoky cabin were observed to be significantly associated with sinusitis (OR = 1.21; p = 0.024, middle ear infections (OR = 1.30; p = 0.006, and asthma (OR = 1.26; p = 0.042. Conclusion We observed a significant association between hours of smoky cabin exposure and self-reported reported sinusitis, middle ear infections, and asthma. Our findings suggest a dose-response between duration of SHS exposure and diseases of the respiratory tract. Our findings add additional evidence to the growing body of knowledge supporting the need for widespread implementation of clean indoor air policies to decrease the risk of adverse health consequences experienced by never smokers exposed to SHS.

    Full Text Available The response of microalgae to photooxidative stress resulting from high light exposure is a well-studied phenomenon. However, direct analyses of photosystem II (PSII D1 protein (the main target of photoinhibition in diatoms are scarce. In this study, the response of the diatom model species Phaeodactylum tricornutum to short-term exposure to high light was examined and the levels of D1 protein determined immunochemically. Low light (LL acclimated cells (40 µmol photons m(-2 s(-1 subjected to high light (HL, 1,250 µmol photons m(-2 s(-1 showed rapid induction of non-photochemical quenching (NPQ and ca. 20-fold increase in diatoxanthin (DT concentration. This resulted from the conversion of diadinoxanthin (DD to DT through the activation of the DD-cycle. D1 protein levels under LL decreased about 30% after 1 h of the addition of lincomycin (LINC, a chloroplast protein synthesis inhibitor, showing significant D1 degradation and repair under low irradiance. Exposure to HL lead to a 3.2-fold increase in D1 degradation rate, whereas average D1 repair rate was 1.3-x higher under HL than LL, leading to decreased levels of D1 protein under HL. There were significant effects of both HL and LINC on P. tricornutum maximum quantum yield of PSII (F(v/F(m, showing a reduction of active PSII reaction centres. Partial recovery of F(v/F(m in the dark demonstrates the photosynthetic resilience of this diatom to changes in the light regime. P. tricornutum showed high allocation of total protein to D1 and an active D1-repair cycle to limit photoinhibition.

    The Arecibo Pisces-Perseus Supercluster Survey is a targeted HI survey of galaxies that began its second observing season in October 2016. The survey is conducted by members of the Undergraduate ALFALFA Team (UAT) and extensively involves undergraduates in observations, data reduction, and analysis. It aims to complement the HI sources identified by the ALFALFA extragalactic HI line survey by probing deeper in HI mass (to lower masses) than the legacy survey itself. Measurements of the HI line velocity widths will be combined with uniform processing of images obtained in the SDSS and GALEX public databases to localize the sample within the baryonic Tully Fisher relation, allowing estimates of their redshift-independent distances and thus their peculiar velocities.The survey is designed to constrain Pisces-Perseus Supercluster infall models by producing 5-σ detections of infall velocities to a precision of about 500 km/s. By targeting galaxies based on SDSS and GALEX photometry, we have achieved detection rates of 68% of the galaxies in our sample. We will discuss the target selection process, HI velocities and mass estimates from the 2015 fall observing season, preliminary results from 2016 observations, and preliminary comparisons with inflow models predicted by numerical simulations.This work has been supported by NSF grants AST-1211005, AST-1637339, AST-1637262.

    In this study, Community Multiscale Air Quality (CMAQ) model was applied to predict ambient gaseous and particulate concentrations during 2001 to 2010 in 15 hospital referral regions (HRRs) using a 36-km horizontal resolution domain. An inverse distance weighting based method was applied to produce exposure estimates based on observation-fused regional pollutant concentration fields using the differences between observations and predictions at grid cells where air quality monitors were located. Although the raw CMAQ model is capable of producing satisfying results for O3 and PM2.5 based on EPA guidelines, using the observation data fusing technique to correct CMAQ predictions leads to significant improvement of model performance for all gaseous and particulate pollutants. Regional average concentrations were calculated using five different methods: 1) inverse distance weighting of observation data alone, 2) raw CMAQ results, 3) observation-fused CMAQ results, 4) population-averaged raw CMAQ results and 5) population-averaged fused CMAQ results. It shows that while O3 (as well as NOx) monitoring networks in the HRRs are dense enough to provide consistent regional average exposure estimation based on monitoring data alone, PM2.5 observation sites (as well as monitors for CO, SO2, PM10 and PM2.5 components) are usually sparse and the difference between the average concentrations estimated by the inverse distance interpolated observations, raw CMAQ and fused CMAQ results can be significantly different. Population-weighted average should be used to account for spatial variation in pollutant concentration and population density. Using raw CMAQ results or observations alone might lead to significant biases in health outcome analyses.

    Full Text Available Abstract Background Persistence is a key factor for long-term blood pressure control, which is of high prognostic importance for patients at increased cardiovascular risk. Here we present the results of a post-marketing survey including 4769 hypertensive patients treated with irbesartan in 886 general practices in Switzerland. The goal of this survey was to evaluate the tolerance and the blood pressure lowering effect of irbesartan as well as the factors affecting persistence in a large unselected population. Methods Prospective observational survey conducted in general practices in all regions of Switzerland. Previously untreated and uncontrolled pre-treated patients were started with a daily dose of 150 mg irbesartan and followed up to 6 months. Results After an observation time slightly exceeding 4 months, the average reduction in systolic and diastolic blood pressure was 20 (95% confidence interval (CI -19.6 to -20.7 mmHg and 12 mmHg (95% CI -11.4 to -12.1 mmHg, respectively. At this time, 26% of patients had a blood pressure Conclusion The results of this survey confirm that irbesartan is effective, well tolerated and well accepted by patients, as indicated by the good persistence. This post-marketing survey also emphasizes the importance of the tolerability profile and of achieving an early control of blood pressure as positive predictors of persistence.

  9. Towards harmonisation of critical laboratory result management - review of the literature and survey of australasian practices.

    Timely release and communication of critical test results may have significant impact on medical decisions and subsequent patient outcomes. Laboratories therefore have an important responsibility and contribution to patient safety. Certification, accreditation and regulatory bodies also require that laboratories follow procedures to ensure patient safety, but there is limited guidance on best practices. In Australasia, no specific requirements exist in this area and critical result reporting practices have been demonstrated to be heterogeneous worldwide.Recognising the need for agreed standards and critical limits, the AACB started a quality initiative to harmonise critical result management throughout Australasia. The first step toward harmonisation is to understand current laboratory practices. Fifty eight Australasian laboratories responded to a survey and 36 laboratories shared their critical limits. Findings from this survey are compared to international practices reviewed in various surveys conducted elsewhere. For the successful operation of a critical result management system, critical tests and critical limits must be defined in collaboration with clinicians. Reporting procedures must include how critical results are identified; who can report and who can receive critical results; what is an acceptable timeframe within which results must be delivered or, if reporting fails, what escalation procedures should follow; what communication channels or systems should be used; what should be recorded and how; and how critical result procedures should be maintained and evaluated to assess impact on outcomes.In this paper we review the literature of current standards and recommendations for critical result management. Key elements of critical result reporting are discussed in view of the findings of various national surveys on existing laboratory practices, including data from our own survey in Australasia. Best practice recommendations are made that laboratories

Three important topics in particle physics, the bounds on neutrinos masses and parameters, on thermal axion mass and on the neutron lifetime derived from cosmological data are reviewed, with attention to the comparison with laboratory experiment results. Recent results from...

    Hypothenar hammer syndrome is a rare cause of ischemic fingers observed mainly in young men smoking cigarettes and it is associated with repeated trauma of the ulnar artery in the area of the hypothenar eminence of the dominant-hand arm, resulting in a deficit of blood supply with the occurrence of hand symptoms typical for chronic and sometimes critical ischemia. Artery injury in this location is most often the result of multiple repetitions of the same activity being mostly the result of occupational exposure. We present a case of a 27-year-old car mechanic admitted to the hospital with symptoms of critical ischemia of the fingers III, IV, and V of the right hand, which resolved after conservative treatment.

    Selenium (Se) leaches into water from agricultural soils and from storage sites for coal fly ash. Se toxicity causes population and community level effects in fishes and birds. We used the laboratory aquarium model fish, Japanese medaka (Oryzias latipes), an asynchronous breeder, to determine aspects of uptake in adults and resultant developmental toxicity in their offspring. The superior imaging properties of the model enabled detailed descriptions of phenotypic alterations not commonly reported in the existing Se literature. Adult males and females in treatment groups were exposed, separately and together, to a dry diet spiked with 0, 12.5, 25, or 50 μg/g (dry weight) seleno-L-methionine (SeMet) for 6 days, and their embryo progeny collected for 5 days, maintained under controlled conditions and observed daily for hatchability, mortality and/or developmental toxicity. Sites of alteration included: craniofacial, pericardium and abdomen (Pc/Ab), notochord, gall bladder, spleen, blood, and swim bladder. Next, adult tissue Se concentrations (liver, skeletal muscle, ovary and testis) were determined and compared in treatment groups of bred and unbred individuals. No significant difference was found across treatment groups at the various SeMet concentrations; and, subsequent analysis compared exposed vs. control in each of the treatment groups at 10 dpf. Increased embryo mortality was observed in all treatment groups, compared to controls, and embryos had a decreased hatching rate when both parents were exposed. Exposure resulted in significantly more total altered phenotypes than controls. When altered phenotypes following exposure of both parents were higher than maternal only exposure, a male role was suggested. The comparisons between treatment groups revealed that particular types of phenotypic change may be driven by the sex of the exposed parent. Additionally, breeding reduced Se concentrations in some adult tissues, specifically the liver of exposed females

    Cotton dust exposures and resulting respiratory disorders among Thai home-based garment workers in Bangkok were explored. Structured interviews focused on occupational health assessments of respiratory disorders; workflow process observations, lung function screening tests, and garment dust density assessments were used to gather data. Results revealed that garment workers in this study had worked in home-based tailoring an average of 14.88 years; 88.5% reported average health status, only 2.6% currently smoked cigarettes, and 8.6% had impaired lung function. The prevalence of respiratory disorders in this occupational group was 25%. Significant respiratory tract signs and symptoms were associated with lung function capacity (odds ratio [OR] = 52.15, 95% confidence interval [CI] = [6.49, 419.60]). Long work hours and few preventive behaviors were significantly associated with respiratory disorders (OR = 2.89 and OR = 10.183, respectively). Improving working conditions at home and minimizing fabric dust exposure among garment workers are recommended.

    Routine evaluation of aircraft crew exposure to cosmic radiation in the Czech Republic is performed by means of calculation method. Measurements onboard aircraft work as a control tool of the routine method, as well as a possibility of comparison of results measured by means of several methods. The following methods were used in 2006: (1) mobile dosimetry unit (MDU) type Liulin—a spectrometer of energy deposited in Si-detector; (2) two types of LET spectrometers based on the chemically etched track detectors (TED); (3) two types of thermoluminescent detectors; and (4) two calculation methods. MDU represents currently one of the most reliable equipments for evaluation of the aircraft crew exposure to cosmic radiation. It is an active device which measures total energy depositions (Edep) in the semiconductor unit, and, after appropriate calibration, is able to give a separate estimation for non-neutron and neutron-like components of H*(10). This contribution consists mostly of results acquired by means of this equipment; measurements with passive detectors and calculations are mentioned because of comparison. Reasonably good agreement of all data sets could be stated.

    We present early results from the JCMT Plane Survey (JPS), which has surveyed the northern inner Galactic plane between longitudes l=7 and l=63 degrees in the 850-{\\mu}m continuum with SCUBA-2, as part of the James Clerk Maxwell Telescope Legacy Survey programme. Data from the l=30 degree survey region, which contains the massive star-forming regions W43 and G29.96, are analysed after approximately 40% of the observations had been completed. The pixel-to-pixel noise is found to be 19 mJy/beam, after a smooth over the beam area, and the projected equivalent noise levels in the final survey are expected to be around 10 mJy/beam. An initial extraction of compact sources was performed using the FellWalker method resulting in the detection of 1029 sources above a 5-{\\sigma} surface-brightness threshold. The completeness limits in these data are estimated to be around 0.2 Jy/beam (peak flux density) and 0.8 Jy (integrated flux density) and are therefore probably already dominated by source confusion in this relativ...

    OmegaWhite is a wide-field, high cadence, synoptic survey targeting fields in the southern Galactic plane, with the aim of discovering short period variable stars. Our strategy is to take a series of 39 s exposures in the g band of a 1 deg2 of sky lasting 2 h using the OmegaCAM wide field imager on the VLT Survey Telescope (VST). We give an overview of the initial 4 yr of data which covers 134 deg2 and includes 12.3 million light curves. As the fields overlap with the VLT Survey Telescope Hα Photometric Survey of the Galactic plane and Bulge (VPHAS+), we currently have ugriHα photometry for ˜1/3 of our fields. We find that a significant fraction of the light curves have been affected by the diffraction spikes of bright stars sweeping across stars within a few dozen of pixels over the two hour observing time interval due to the alt-az nature of the VST. We select candidate variable stars using a variety of variability statistics, followed by a manual verification stage. We present samples of several classes of short period variables, including: an ultra compact binary, a DQ white dwarf, a compact object with evidence of a 100 min rotation period, three CVs, one eclipsing binary with an 85 min period, a symbiotic binary which shows evidence of a 31 min photometric period, and a large sample of candidate δ Sct type stars including one with a 9.3 min period. Our overall goal is to cover 400 deg2, and this study indicates we will find many more interesting short period variable stars as a result.

    The Czech Republic Global Youth Tobacco Survey (GYTS) is a school-based survey of students in grades 7-9, conducted in 2002. A two-stage cluster sample design was used to produce representative data for all of the Czech Republic. On a large sample of students (N=4,149) from 7-9th grade it reveals that smoking among children has been continually growing. According to the results of this study, over 34% of the respondents smoke. Results of the study help us to understand social and attitudinal factors that affect adolescent smoking habits. Social factors include particularly the convenient availability of cigarettes and the lack of the legal regulation of the retail of cigarettes: over one half of all smokers under 15 years of age regularly purchase cigarettes in regular retail outlets; 72% of them reported never having been restricted in their purchases because of their age. Advertising and media coverage appears to be another important factor that affects smoking in this age group. Over 80% of children under 15 years of age reported that they have been exposed to the tobacco advertising. The study also allows an interesting analysis of the exposure to the environmental tobacco smoke. Compared to non-smokers, this exposure has been significantly higher in the case of smokers--both in their homes and at other locations (58% vs. 25%, and 90% vs. 57% respectively). The analysis of the data also revealed a strong misconception about the health risks related to passive smoking among smokers. The study provides three key findings for health promotion: (1) it is necessary to exert a continuous pressure on the political representation to strictly enforce the regulations of tobacco distribution and availability to minors; (2) school health education as well as community oriented prevention programs need to explicitly communicate non-smoking as a standard; and (3) it is important to increase the attractiveness and availability of smoking cessation programs.

  20. Exposure to Zinc Sulfate Results in Differential Effects on Olfactory Sensory Neuron Subtypes in Adult Zebrafish

    2016-08-01

    Full Text Available Zinc sulfate is a known olfactory toxicant, although its specific effects on the olfactory epithelium of zebrafish are unknown. Olfactory organs of adult zebrafish were exposed to zinc sulfate and, after 2, 3, 5, 7, 10 or 14 days, fish were processed for histological, immunohistochemical, ultrastructural, and behavioral analyses. Severe morphological disruption of the olfactory organ was observed two days following zinc sulfate exposure, including fusion of lamellae, epithelial inflammation, and significant loss of anti-calretinin labeling. Scanning electron microscopy revealed the apical surface of the sensory region was absent of ciliated structures, but microvilli were still present. Behavioral analysis showed significant loss of the ability to perceive bile salts and some fish also had no response to amino acids. Over the next several days, olfactory organ morphology, epithelial structure, and anti-calretinin labeling returned to control-like conditions, although the ability to perceive bile salts remained lost until day 14. Thus, exposure to zinc sulfate results in rapid degeneration of the olfactory organ, followed by restoration of morphology and function within two weeks. Zinc sulfate appears to have a greater effect on ciliated olfactory sensory neurons than on microvillous olfactory sensory neurons, suggesting differential effects on sensory neuron subtypes.

    Behavioral resilience in mosquitoes poses a significant challenge to mosquito control. Although behavior changes in anopheline vectors have been reported over the last decade, there are no empirical data to suggest they compromise the efficacy of vector control in reducing malaria transmission. In this study, we quantified human exposure to both bites and infective bites of a major malaria vector in Papua New Guinea over the course of 4 years surrounding nationwide bednet distribution. We also quantified malaria infection prevalence in the human population during the same time period. We observed a shift in mosquito biting to earlier hours of the evening, before individuals are indoors and protected by bednets, followed by a return to preintervention biting rates. As a result, net users and non-net users experienced higher levels of transmission than before the intervention. The personal protection provided by a bednet decreased over the study period and was lowest in the adult population, who may be an important reservoir for transmission. Malaria prevalence decreased in only 1 of 3 study villages after the distribution. This study highlights the necessity of validating and deploying vector control measures targeting outdoor exposure to control and eliminate malaria.

    We report constraints on spin-independent weakly interacting massive particle (WIMP)-nucleon scattering using a 3.35×10^{4}  kg day exposure of the Large Underground Xenon (LUX) experiment. A dual-phase xenon time projection chamber with 250 kg of active mass is operated at the Sanford Underground Research Facility under Lead, South Dakota (USA). With roughly fourfold improvement in sensitivity for high WIMP masses relative to our previous results, this search yields no evidence of WIMP nuclear recoils. At a WIMP mass of 50  GeV c^{-2}, WIMP-nucleon spin-independent cross sections above 2.2×10^{-46}  cm^{2} are excluded at the 90% confidence level. When combined with the previously reported LUX exposure, this exclusion strengthens to 1.1×10^{-46}  cm^{2} at 50  GeV c^{-2}.

    The evaluation of incoherent artificial optical radiation (AOR) exposure in hospital environments is a complex task due to the variety of sources available. This study has been designed to provide a proposal for the precautionary assessment of the related risk. This survey suggested that, in our Institution, at least three kinds of AOR sources required specific investigations: ambient lighting, theatre operating lighting and ultraviolet radiation (UVR) sources. For each kind of evaluated sources a specific measurement approach was developed. All irradiance measurements were made using a commercial spectroradiometer. The obtained results were compared with the appropriate exposure limit values (ELVs) defined in the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines and adopted by the European Directive 2006/25/EC. The risk related to the evaluated AOR exposure was finally assessed according to our risk matrix. According to our results, the emission of ambient lighting in the actual exposure conditions was always in accordance with the ELVs and the related risk was classifiable as not relevant. The risk related to the exposure to theatre operating lighting resulted not negligible, especially when two or more sources were used with focal spots overlapping on reflective objects. UVR sources emission may represent a health hazard depending, in particular, on the set up of the device containing the source. In case of laminar flow cabinets and closed transilluminators, if the UVR source is well contained within an enclosure with interlock, it presents no risk of exposure. Otherwise, the emission arising from UVR lamps, open transilluminators or sources not provided with interlock, may represent a risk classifiable as high even in the actual working conditions. The personal protective equipment used by workers were also assessed and their suitability was discussed.

    We present the results of the 2015 quality metrics (QUALMET) survey, which was designed to assess the commonalities and variability of selected quality and productivity metrics currently employed by a large sample of academic radiology departments representing all regions in the USA. The survey of key radiology metrics was distributed in March-April of 2015 via personal e-mail to 112 academic radiology departments. There was a 34.8% institutional response rate. We found that most academic departments of radiology commonly utilize metrics of hand hygiene, report turn around time (RTAT), relative value unit (RVU) productivity, patient satisfaction and participation in peer review. RTAT targets were found to vary widely. The implementation of radiology peer review and the variety of ways in which peer review results are used within academic radiology departments, the use of clinical decision support tools and requirements for radiologist participation in Maintenance of Certification also varied. Policies for hand hygiene and critical results communication were very similar across all institutions reporting, and most departments utilized some form of missed case/difficult case conference as part of their quality and safety programme, as well as some form of periodic radiologist performance reviews. Results of the QUALMET survey suggest many similarities in tracking and utilization of the selected quality and productivity metrics included in our survey. Use of quality indicators is not a fully standardized process among academic radiology departments. Advances in knowledge: This article examines the current quality and productivity metrics in academic radiology.

    2014-12-01

    The purpose of this study was to characterize the climate and culture experienced by lesbian, gay, bisexual, and transgender (LGBT) employees and students at one large academic medical center. An anonymous, online institutional climate survey was used to assess the attitudes and experiences of LGBT employees and students. There were 42 LGBT and 14 non-LGBT survey participants. Results revealed that a surprisingly large percentage of LGBT individuals experienced pressure to remain "closeted" and were harassed despite medical center policies of non-discrimination. Continuing training, inclusive policies and practices, and the development of mechanisms to address LGBT-specific harassment are necessary for improving institutional climate.

    A survey of 800 offroad vehicle (ORV) owners at Big Cypress National Preserve, Florida, was conducted to obtain information on visitor characteristics and management preferences. This report characterizes survey results for riders of all-terrain vehicles, swamp buggies, standard 4-wheeled street vehicles, and airboats. Riders tended to feel satisfied with their ORV experiences and Preserve conditions. Riders were strongly opposed to management approaches that would restrict use or require certain behaviors. More favored were management actions to encourage low impact use practices

    Bouhours, Brigitte; Broadhurst, Roderic

    2015-11-01

    In Hong Kong, nearly 1,300 women participated by telephone in the International Violence Against Women Survey in 2006. One in five respondents had experienced violence since age 16. Sexual violence (13.4%) was more frequent than physical violence (11.7%). Women were more likely to be abused by men they knew (13.5%) than by strangers (8%). Compared with other surveyed countries, Hong Kong recorded among the lowest rates of violence by both intimate partners and non-partners. These results suggest that cultural influences linked to the interaction of modernization and some protective factors found in the adherence to traditional Chinese values are relevant.

    Full Text Available In this article, we present the preliminary results of a national survey conducted by INDIRE on head teachers communities and professional networks. About one-fourth of the total population of Italian public school leaders participated in the survey. One of the main intents of this research is to contribute to understanding of the phenomenon of professional networks frequented by school leaders and to pave the way for a further reflection on how to use such networks for head teachers’ training so as to support their daily professional practice conducted too often in isolation.

    The Galactic O-Star Spectroscopic Survey (GOSSS) is a project that is observing all known Galactic O stars with B < 13 (~2000 objects) in the blue-violet part of the spectrum with R~2500. It also includes two companion surveys (a spectroscopic one at R~1500 and a high resolution imaging one). It is based on v2.0 of the Galactic O star catalog (v1, Ma\\'iz-Apell\\'aniz et al. 2004; v2, Sota et al. 2008). We have completed the first part of the main project. Here we present results on the first 400 objects of the sample.

    2010-01-01

    When complete, the ALFALFA survey catalog will cover 7000 square degrees and provide a catalog with 30,000 detections, improving our understanding of the density of HI in the local Universe and its environmental dependence. Following 585 observing runs with a total of 3400 hours of telescope time, observations for the ALFALFA survey are now 77% complete. Data reduction and catalog production has been completed for two large contiguous sections in the Virgo and anti-Virgo directions ( 1600 and 530 square degrees, respectively), and the ALFALFA survey now has the largest sample of blindly HI-selected galaxies. The regions analyzed here are 07h30ALFALFA Survey and contain on the order of 10,000 HI selected galaxies in a range of local environments, out to distances of 250 Mpc. In particular, this catalog contains 300 galaxies with log HI mass less than 8.0 solar masses, providing a robust determination of the low-mass end of the HI mass function presented here. Along with these preliminary results, we compare the HI mass function in the region containing the overdense Virgo cluster to that in the anti-Virgo direction, which includes the void in the foreground of the Pisces-Perseus supercluster. Finally, we discuss future improvements to this first HI mass function estimate from the ALFALFA survey. This work is partly supported by NSF grant AST-0607007 and the Brinson Foundation.

    2017-01-01

    The IMIA-NIstudents' and emerging professionals' working group conducted a large international survey in 2015 regarding research trends in nursing informatics. The survey was translated into half-a-dozen languages and distributed through 18 international research collaborators' professional connections. The survey focused on the perspectives of nurse informaticians. A total of 272 participants responded to an open ended question concerning recommendations to advance nursing informatics. Five key areas for action were identified through our thematic content analysis: education, research, practice, visibility and collaboration. This chapter discusses these results with implications for nursing competency development. We propose how components of various competency lists might support the key areas for action. We also identify room to further develop existing competency guidelines to support in-service education for practicing nurses, promote nursing informatics visibility, or improve and facilitate collaboration and integration with other professions.

    This report presents the findings of the annual inspection and radiological survey of the Piqua, Ohio, Decommissioned Reactor Site (site). The decommissioned nuclear power demonstration facility was inspected and surveyed on April 15, 2016. The site, located on the east bank of the Great Miami River in Piqua, Ohio, was in fair physical condition. There is no requirement for a follow-up inspection, partly because City of Piqua (City) personnel participated in a March 2016 meeting to address reoccurring safety concerns. Radiological survey results from 104 locations revealed no removable contamination. One direct beta activity reading in a floor drain on the 56-foot level (1674 disintegrations per minute [dpm]/100 square centimeters [cm2]) exceeded the minimum detectable activity (MDA). Beta activity has been detected in the past at this floor drain. The reading was well below the action level of 5000 dpm/100 cm2.

    Zwickl, Benjamin M; Finkelstein, Noah; Lewandowski, H J

    2013-01-01

    In response to national calls to better align physics laboratory courses with the way physicists engage in research, we have developed an epistemology and expectations survey to assess how students perceive the nature of physics experiments in the contexts of laboratory courses and the professional research laboratory. The Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS) evaluates students' shifts in epistemology and affect at the beginning and end of a semester. Also, at the end of the semester, the E-CLASS assesses students' reflections on their course's expectations for earning a good grade. By basing survey statements on widely embraced learning goals and common critiques of teaching labs, the E-CLASS serves as an assessment tool for lab courses across the undergraduate curriculum and as a tool for PER research. We present the development, evidence of validation, and initial formative assessment results from a sample that includes 45 classes at 20 institutions. We also d...

  15. Tobacco exposure and diabetes-related autoantibodies in children: results from the ABIS study.

    Passive smoking has decreased in recent years ("increased hygiene"). Less environmental tobacco smoke (ETS) gives increased hygiene that, if the hygiene hypothesis is true, in turn might give more autoimmune diseases. The presence of auto antibodies is considered to be an early indicator of type 1 diabetes (T1D). Because tobacco exposure may influence the immune system, we analyzed the relation between passive smoking and development of autoantibodies. A subsample (n= 8794) of the children in the ABIS study was used for this analysis. The parents answered questionnaires on smoking from pregnancy and onwards, and blood samples from the children aged 2.5-3 years were analyzed for GADA and IA-2A. Results showed that there was no significant difference in the prevalence of GADA or IA-2A (>95 percentile) between tobacco-exposed and nonexposed children. It was concluded that passive smoking does not seem to influence development of diabetes-related autoantibodies early in life.

    We report constraints on spin-independent weakly interacting massive particle (WIMP)-nucleon scattering using a 3.35e4 kg-day exposure of the Large Underground Xenon (LUX) experiment. A dual-phase xenon time projection chamber with 250 kg of active mass is operated at the Sanford Underground Research Facility under Lead, South Dakota (USA). With roughly four-fold improvement in sensitivity for high WIMP masses relative to our previous results, this search yields no evidence of WIMP nuclear recoils. At a WIMP mass of 50 GeV/c^2, WIMP-nucleon spin-independent cross sections above 2.2e-46 cm^2 are excluded at the 90% confidence level.

    We report the results of a weakly-interacting massive particle (WIMP) dark matter search using the full 80.1\\;live-day exposure of the first stage of the PandaX experiment (PandaX-I) located in the China Jin-Ping Underground Laboratory. The PandaX-I detector has been optimized for detecting low-mass WIMPs, achieving a photon detection efficiency of 9.6\\%. With a fiducial liquid xenon target mass of 54.0\\,kg, no significant excess event were found above the expected background. A profile likelihood analysis confirms our earlier finding that the PandaX-I data disfavor all positive low-mass WIMP signals reported in the literature under standard assumptions. A stringent bound on the low mass WIMP is set at WIMP mass below 10\\,GeV/c$^2$, demonstrating that liquid xenon detectors can be competitive for low-mass WIMP searches.

  18. Lessons learnt on biases and uncertainties in personal exposure measurement surveys of radiofrequency electromagnetic fields with exposimeters.

    Bolte, John F B

    2016-09-01

    Personal exposure measurements of radio frequency electromagnetic fields are important for epidemiological studies and developing prediction models. Minimizing biases and uncertainties and handling spatial and temporal variability are important aspects of these measurements. This paper reviews the lessons learnt from testing the different types of exposimeters and from personal exposure measurement surveys performed between 2005 and 2015. Applying them will improve the comparability and ranking of exposure levels for different microenvironments, activities or (groups of) people, such that epidemiological studies are better capable of finding potential weak correlations with health effects. Over 20 papers have been published on how to prevent biases and minimize uncertainties due to: mechanical errors; design of hardware and software filters; anisotropy; and influence of the body. A number of biases can be corrected for by determining multiplicative correction factors. In addition a good protocol on how to wear the exposimeter, a sufficiently small sampling interval and sufficiently long measurement duration will minimize biases. Corrections to biases are possible for: non-detects through detection limit, erroneous manufacturer calibration and temporal drift. Corrections not deemed necessary, because no significant biases have been observed, are: linearity in response and resolution. Corrections difficult to perform after measurements are for: modulation/duty cycle sensitivity; out of band response aka cross talk; temperature and humidity sensitivity. Corrections not possible to perform after measurements are for: multiple signals detection in one band; flatness of response within a frequency band; anisotropy to waves of different elevation angle. An analysis of 20 microenvironmental surveys showed that early studies using exposimeters with logarithmic detectors, overestimated exposure to signals with bursts, such as in uplink signals from mobile phones and Wi

    Full Text Available The present article intends to analyze the exposure of Romanian children and teens to sexually explicit message and the so-called „sexting” activities they perform in the online environment. The main research topic to which we try to find some answers is: are young people more exposed to risks because they view sexually explicit content online and send sexual messages to others? Our results validate the risk migration hypothesis, the blurring boundaries between the online and offline worlds enabling the migration of risk from the real world to the internet and the reverse. At the same time, the date of EU Kinds Online II validate the vulnerability hypothesis, according to which the harm declared by the children following the exposure to sexually explicit images and the receiving the sexual messages is the result of their socio-demographic vulnerabilities

    An exposure assessment of hot-mix asphalt (HMA) paving workers was conducted to determine which of four exposure scenarios impacted worker exposure and dose. Goals of this report are to present the personal-breathing zone (PBZ) data, discuss the impact of substituting the releasing/cleaning agent, and discuss work practices that resulted in the highest exposure concentration for each analyte. One-hundred-seven PBZ samples were collected from HMA paving workers on days when diesel oil was used as a releasing/cleaning agent. An additional 36 PBZ samples were collected on days when B-100 (100% biodiesel, containing no petroleum-derived products) was used as a substitute releasing/cleaning agent. Twenty-four PBZ samples were collected from a reference group of concrete workers, who also worked in outdoor construction but had no exposure to asphalt emissions. Background and field blank samples were also collected daily. Total particulates and the benzene soluble fraction were determined gravimetrically. Total organic matter was determined using gas chromatography (GC) with flame ionization detection and provided qualitative information about other exposure sources contributing to worker exposure besides asphalt emissions. Thirty-three individual polycyclic aromatic compounds (PACs) were determined using GC with time-of-flight mass spectrometry; results were presented as either the concentration of an individual PAC or a summation of the individual PACs containing either 2- to 3-rings or 4- to 6-rings. Samples were also screened for PACs containing 4- to 6-rings using fluorescence spectroscopy. Arithmetic means, medians, and box plots of the PBZ data were used to evaluate trends in the data. Box plots illustrating the diesel oil results were more variable than the B-100. Also, the highest diesel oil results were much higher in concentration than the highest B-100 results. An analysis of the highest exposure results and field notes revealed a probable association between

    The association between exposure to welding fume and chronic obstructive pulmonary disease (COPD) has been insufficiently clarified. In this study we assessed the influence of exposure to welding fume on lung function parameters. We investigated forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), FEV1/FVC, and expiratory flow rates in 219 welders. We measured current exposure to respirable particles and estimated a worker's lifetime exposure considering welding techniques, working conditions and protective measures at current and former workplaces. Multiple regression models were applied to estimate the influence of exposure to welding fume, age, and smoking on lung function. We additionally investigated the duration of working as a welder and the predominant welding technique. The findings were that age- and smoking-adjusted lung function parameters showed no decline with increasing duration, current exposure level, and lifetime exposure to welding fume. However, 15% of the welders had FEV1/FVC below the lower limit of normal, but we could not substantiate the presence of an association with the measures of exposure. Adverse effects of cigarette smoking were confirmed. In conclusion, the study did not support the notion of a possible detrimental effect of exposure to welding fume on lung function in welders.

    From July to August 2014, Epilepsia conducted an online survey seeking opinions that explained the discrepancy between the incidence and prevalence of epilepsy in lower income countries. Data on cumulative incidence suggest a higher rate of active epilepsy than reported in lifetime prevalence surveys. This study reports the findings of that poll addressing the proposal in our Controversy in Epilepsy series that it could be from increased death rates. The survey consisted of a question addressing possible reasons to explain the discrepancy between the incidence and prevalence of epilepsy. Another four questions addressed demographic information. There were 34 responders who completed the survey. Half (50%) of the responders felt that the discrepancy between cumulative incidence and lifetime prevalence was due to lack of uniform definitions and misclassification of patients in study design, 23.5% said the discrepancy was due to a higher mortality from diseases and conditions such as trauma and infections associated with epilepsy, 23.5% indicated that the stigma of epilepsy prevented people from acknowledging their disease in prevalence surveys, and 2.9% felt it was from poor access to qualified medical personal and utilization of medical treatments that increased death rates directly related to epilepsy. Within the limitations of sample size, the results of this survey support that the discrepancy between the incidence and prevalence of epilepsy in lower income regions of the world is due to problems in acquiring the data and stigma rather than higher mortality from diseases associated with epilepsy and repeated seizures.

    VISTA Variables in the Via Lactea (VVV) is an ESO variability survey that is performing observations in near-infrared bands (ZY JHK{sub s}) toward the Galactic bulge and part of the disk with the completeness limits at least 3 mag deeper than Two Micron All Sky Survey. In the present work, we searched in the VVV survey data for background galaxies near the Galactic plane using ZY JHK{sub s} photometry that covers 1.636 deg{sup 2}. We identified 204 new galaxy candidates by analyzing colors, sizes, and visual inspection of multi-band (ZY JHK{sub s}) images. The galaxy candidate colors were also compared with the predicted ones by star count models considering a more realistic extinction model at the same completeness limits observed by VVV. A comparison of the galaxy candidates with the expected one by Millennium simulations is also presented. Our results increase the number density of known galaxies behind the Milky Way by more than one order of magnitude. A catalog with galaxy properties including ellipticity, Petrosian radii, and ZY JHK{sub s} magnitudes is provided, as well as comparisons of the results with other surveys of galaxies toward the Galactic plane.

    We present the first results from the B-fields In STar-forming Region Observations (BISTRO) survey, using the Sub-millimetre Common-User Bolometer Array 2 camera, with its associated polarimeter (POL-2), on the James Clerk Maxwell Telescope in Hawaii. We discuss the survey’s aims and objectives. We describe the rationale behind the survey, and the questions that the survey will aim to answer. The most important of these is the role of magnetic fields in the star formation process on the scale of individual filaments and cores in dense regions. We describe the data acquisition and reduction processes for POL-2, demonstrating both repeatability and consistency with previous data. We present a first-look analysis of the first results from the BISTRO survey in the OMC 1 region. We see that the magnetic field lies approximately perpendicular to the famous “integral filament” in the densest regions of that filament. Furthermore, we see an “hourglass” magnetic field morphology extending beyond the densest region of the integral filament into the less-dense surrounding material, and discuss possible causes for this. We also discuss the more complex morphology seen along the Orion Bar region. We examine the morphology of the field along the lower-density northeastern filament. We find consistency with previous theoretical models that predict magnetic fields lying parallel to low-density, non-self-gravitating filaments, and perpendicular to higher-density, self-gravitating filaments.

    Full Text Available Flood hazards perception. The result of an opinion survey made in the little towns from lower Arieş corridor. This paper has been prepared based on information obtained from a survey conducted on a sample of 560 residents from the towns of Turda and Câmpia Turzii, residing in areas with different degrees of exposure to the risk of flooding. The residents were questioned about the floods they had suffered and gave varied responses to the degree of flood damage on the population, to the amount of information and the degree of insurance against floods. The questionnaire was structured on different aspects that emphasized: identification, level of experience, knowledge and information; the perception of the causes that generated and amplified floods; the perception involving authorities in prevention and mitigation of flood damage; availability for implementation of voluntary actions, the degree of insurance and aid to flood. In this study it was taken into account the location of households, the previous flood experience, the age and the education level of the respondents.

    Environmental exposures during pregnancy and early life may have adverse health effects. Single birth cohort studies often lack statistical power to tease out such effects reliably. To improve the use of existing data and to facilitate collaboration among these studies, an inventory of the environmental exposure and health data in these studies was made as part of the ENRIECO (Environmental Health Risks in European Birth Cohorts) project. The focus with regard to exposure was on outdoor air pollution, water contamination, allergens and biological organisms, metals, pesticides, smoking and second hand tobacco smoke (SHS), persistent organic pollutants (POPs), noise, radiation, and occupational exposures. The review lists methods and data on environmental exposures in 37 European birth cohort studies. Most data is currently available for smoking and SHS (N=37 cohorts), occupational exposures (N=33), outdoor air pollution, and allergens and microbial agents (N=27). Exposure modeling is increasingly used for long-term air pollution exposure assessment; biomonitoring is used for assessment of exposure to metals, POPs and other chemicals; and environmental monitoring for house dust mite exposure assessment. Collaborative analyses with data from several birth cohorts have already been performed successfully for outdoor air pollution, water contamination, allergens, biological contaminants, molds, POPs and SHS. Key success factors for collaborative analyses are common definitions of main exposure and health variables. Our review emphasizes that such common definitions need ideally be arrived at in the study design phase. However, careful comparison of methods used in existing studies also offers excellent opportunities for collaborative analyses. Investigators can use this review to evaluate the potential for future collaborative analyses with respect to data availability and methods used in the different cohorts and to identify potential partners for a specific research

    Adverse environment in early life can modulate the adult phenotype, including blood pressure. Lipopolysaccharide (LPS) exposure in utero results in increased blood pressure in the offspring, but the exact mechanisms are not clear. Studies have shown that the renal dopamine D1 receptor (D1R) plays an important role in maintaining sodium homeostasis and normal blood pressure; dysfunction of D1R is associated with oxidative stress and hypertension. In this study, we determined if dysfunction of the renal D1R is involved in fetal-programmed hypertension, and if oxidative stress contributes to this process. Pregnant Sprague-Dawley (SD) rats were intraperitoneally injected with LPS (0.79 mg/kg) or saline at gestation days 8, 10, and 12. As compared with saline-injected (control) dams, offspring of LPS-treated dams had increased blood pressure, decreased renal sodium excretion, and increased markers of oxidative stress. In addition, offspring of LPS-treated dams had decreased renal D1R expression, increased D1R phosphorylation, and G protein-coupled receptor kinase type 2 (GRK2) and type 4 (GRK4) protein expression, and impaired D1R-mediated natriuresis and diuresis. All of the findings in the offspring of LPS-treated dams were normalized after treatment with TEMPOL, an oxygen free radical scavenger. In conclusion, prenatal LPS exposure, via an increase in oxidative stress, impairs renal D1R function and leads to hypertension in the offspring. Normalization of renal D1R function by amelioration of oxidative stress may be a therapeutic target of fetal programming of hypertension.

    The assessment of magnetic field exposure in children is an important point in the context of epidemiological issues. EXPERS is the first study ever carried out measuring personal exposure to extremely low frequency magnetic fields at a national scale, involving 977 French children with 24 h personal measurements. Descriptive statistical analyses were performed for all the children, and only for children where no alarm clock was identified, as in some cases this requirement of the measurement protocol was not respected. The proportion of children with a 24 h arithmetic mean of ≥0.4 μT was 3.1% when considering all children and 0.8% when excluding alarm clocks. The alarm clocks were the main variable linked to the child exposure measurements. Magnetic field exposure increased when the home was located close to a high voltage power line. However, none of the 0.8% of children living at 0.4 μT. A multiple correspondence analysis showed the difficulty to build a statistical model predicting child exposure. The distribution of child personal exposure was significantly different from the distribution of exposure during sleep, questioning the exposure assessment in some epidemiological studies.

    Full Text Available Exposure to tobacco product marketing promotes the initiation, continuation, and reuptake of cigarette smoking and as a result the World Health Organization Framework Convention on Tobacco Control (WHO FCTC has called upon member Parties to enact comprehensive bans on tobacco advertising and promotion. This study examines the immediate and long term effectiveness of advertising restrictions enacted in different countries on exposure to different forms of product marketing, and examines differences in exposure across different socioeconomic status (SES groups. Nationally representative data from the United Kingdom, Canada, Australia, and the United States, collected from adult smokers between 2002 and 2008 using the International Tobacco Control Four Country Survey (ITC-4, were used in this study (N = 21,615. In light of the specific marketing regulation changes that occurred during the course of this study period, changes in awareness of tobacco marketing via various channels were assessed for each country, and for different SES groups within countries. Tobacco marketing regulations, once implemented, were associated with significant reductions in smokers’ reported awareness of pro-smoking cues, and the observed reductions were greatest immediately following the enactment of regulations. Changes in reported awareness were generally the same across different SES groups, although some exceptions were noted. While tobacco marketing regulations have been effective in reducing exposure to certain types of product marketing there still remain gaps, especially with regard to in-store marketing and price promotions.

    Background Kawasaki disease (KD) has been reported in many countries. However, the incidence of KD in Mongolia is not known. This is the first report of incident cases of KD in Mongolia, which were identified using data from 2 nationwide surveys. Methods Two nationwide retrospective surveys were conducted: medical histories were collected from patients aged 0 to 16 years who were hospitalized countrywide between 1996 and 2008. Hospital records for these patients were also reviewed. Nationwide training seminars on KD were conducted before each survey. Results For the nationwide surveys, the participation rates among all hospitals with pediatric wards were 97% and 94%. Inpatient medical histories from 1996 through 2008 were reviewed, and, among children younger than 16 years, 9 patients with KD were investigated. The age of KD patients ranged from 1.4 to 14 years; 7 of 9 patients were male. Six (67%) patients fulfilled all 6 clinical diagnostic criteria; the other 3 (33%) were defined as having KD based on the presence of 5 such criteria. Fever persisting 5 or more days, bilateral conjunctival congestion, and changes of the lips and oral cavity were the most common symptoms, and cervical lymphadenopathy was the least common symptom. Cardiac sequelae developed in 5 of the patients, 4 of whom were older than 10 years. Conclusions The results of these nationwide surveys reveal that KD cases do exist in Mongolia. However, knowledge of KD among Mongolian pediatricians is likely to be poor. Thus, there is a need to augment their understanding to improve management of KD patients. Further studies are crucial to clarify the epidemiologic characteristics of KD in Mongolia. PMID:21691035

    Addiction beliefs about tobacco use are associated with intentions to use and use of tobacco products. Exposure to information about tobacco products in media sources may affect addiction beliefs. To examine the relationship between media exposure and tobacco product addiction beliefs. A nationally representative sample of US adults (n=3738) from the 2015 National Cancer Institute's Health Information National Trends Survey was used to examine addiction beliefs about cigarettes, cigars, smokeless tobacco, electronic cigarettes, hookah/waterpipe tobacco, and roll-your-own cigarettes. We used logistic regression to examine the relationship between media exposure and addiction beliefs. We defined media exposure by hours exposed, as well as exposure to tobacco use health effects information through media sources including social media. We categorized media sources by whether respondents actively or passively engaged with the source. A majority (60.6% to 87.3%) of respondents believed that cigarettes, cigars, roll-your-own cigarettes and smokeless tobacco are addictive. Less than half of respondents believed that electronic cigarettes or hookah/waterpipes are addictive (45.2% and 49.8%, respectively). Respondents exposed to messages about tobacco use health effects on active media channels (e.g., social media) had greater odds of believing that smokeless tobacco (adjusted odds ratio [AOR]=1.48), hookah/waterpipe (AOR=1.69), and roll-your-own cigarettes (AOR=1.61) are addictive. Respondents exposed to tobacco use health effects messages on passive media channels (e.g., television), had greater odds of believing that cigarettes (AOR=2.76) and electronic cigarettes (AOR=2.12) are addictive. US adult exposure to information about the health effects of tobacco use was associated with addiction beliefs about tobacco products. Published by Elsevier Ltd.

    Since the 1970s, the federal government has spearheaded major national education programs to reduce the burden of chronic diseases in the United States. These prevention and disease management programs communicate critical information to the public, those affected by the disease, and health care providers. The National Diabetes Education Program (NDEP), the leading federal program on diabetes sponsored by the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC), uses primary and secondary quantitative data and qualitative audience research to guide program planning and evaluation. Since 2006, the NDEP has filled the gaps in existing quantitative data sources by conducting its own population-based survey, the NDEP National Diabetes Survey (NNDS). The NNDS is conducted every 2–3 years and tracks changes in knowledge, attitudes and practice indicators in key target audiences. This article describes how the NDEP has used the NNDS as a key component of its evaluation framework and how it applies the survey results for strategic planning and program improvement. The NDEP's use of the NNDS illustrates how a program evaluation framework that includes periodic population-based surveys can serve as an evaluation model for similar national health education programs.

    STREGA (STRucture and Evolution of the GAlaxy) is a Guaranteed Time survey being performed at the VST (the ESO VLT Survey Telescope) to map about 150 square degrees in the Galactic halo, in order to constrain the mechanisms of galactic formation and evolution. The survey is built as a five-year project, organized in two parts: a core program to explore the surrounding regions of selected stellar systems and a second complementary part to map the southern portion of the Fornax orbit and extend the observations of the core program. The adopted stellar tracers are mainly variable stars (RR~Lyraes and Long Period Variables) and Main Sequence Turn-off stars for which observations in the g,r,i bands are obtained. We present an overview of the survey and some preliminary results for three observing runs that have been completed. For the region centered on $\\omega$~Cen (37 deg^2), covering about three tidal radii, we also discuss the detected stellar density radial profile and angular distribution, leading to the ide...

    2011-12-01

    Physiology faculty members at a wide range of institutions (2-yr colleges to medical schools) were surveyed to determine what core principles of physiology they want their students to understand. From the results of the first survey, 15 core principles were described. In a second survey, respondents were asked to rank order these 15 core principles and, independently, to identify the three most important for their students to understand. The five most important core principles were "cell membrane," "homeostasis," "cell-to-cell communications," "interdependence," and "flow down gradients." We then "unpacked" the flow down gradients core principle into the component ideas of which it is comprised. This unpacking was sent to respondents who were asked to identify the importance of each of the component ideas. Respondents strongly agreed with the importance of the component ideas we had identified. We will be using the responses to our surveys as we begin the development of a conceptual assessment of physiology instrument (i.e., a concept inventory).

    Biomedical informatics programs exist in many countries. Some analyses of the skills needed and of recommendations for curricular content for such programs have been published. However, not much is known of the job profiles and job careers of their graduates. To analyse the job profiles and job careers of 175 graduates of the biomedical informatics bachelor and master program of the Tyrolean university UMIT. Survey of all biomedical informatics students who graduated from UMIT between 2001 and 2013. Information is available for 170 graduates. Eight percent of graduates are male. Of all bachelor graduates, 86% started a master program. Of all master graduates, 36% started a PhD. The job profiles are quite diverse: at the time of the survey, 35% of all master graduates worked in the health IT industry, 24% at research institutions, 9% in hospitals, 9% as medical doctors, 17% as informaticians outside the health care sector, and 6% in other areas. Overall, 68% of the graduates are working as biomedical informaticians. The results of the survey indicate a good job situation for the graduates. The job opportunities for biomedical informaticians who graduated with a bachelor or master degree from UMIT seem to be quite good. The majority of graduates are working as biomedical informaticians. A larger number of comparable surveys of graduates from other biomedical informatics programs would help to enhance our knowledge about careers in biomedical informatics.

    Maywood Chemical Works (MCW) of Maywood, New Jersey, generated process wastes and residues associated with the production and refining of thorium and thorium compounds from monazite ores from 1916 to 1956. MCW supplied rare earth metals and thorium compounds to the Atomic Energy Commission and various other government agencies from the late 1940s to the mid-1950s. Area residents used the sandlike waste from this thorium extraction process mixed with tea and cocoa leaves as mulch in their yards. Some of these contaminated wastes were also eroded from the site into Lodi Brook. At the request of the US Department of Energy (DOE), a group from Oak Ridge National Laboratory conducts investigative radiological surveys of properties in the vicinity of MCW to determine whether a property is contaminated with radioactive residues, principally /sup 232/Th, derived from the MCW site. The survey typically includes direct measurement of gamma radiation levels and soil sampling for radionuclide analyses. The survey of this site, 17 Redstone Lane, Lodi, New Jersey (LJ030), was conducted during 1985 and 1986. Results of the survey demonstrated radionuclide concentrations in excess of the DOE Formerly Utilized Sites Remedial Action Program criteria. The radionuclide distributions are typical of the type of material originating from the MCW site. 4 refs., 7 figs., 3 tabs.

    We present a magnetic survey conducted in the offshore region between Cabo da Roca and Sesimbra (mouth of Tagus River, Portugal). Strong magnetic anomalies are recognized in this area since a first marine survey in 1958 (Allan, 1965) and by further aeromagnetic survey (c.f. Silva et al, 2000). The anomalies have been linked to Cretaceous magmatic events related to the Upper Cretaceous Sintra magmatic complex and Lisbon volcanic complex, but their geometry and extension has yet not been resolved. The aim of the present survey was to unravel the location, geometry and type of the magnetic sources, thus contributing for the characterization of the main magmatic and tectonic features in the region. The survey was conducted in two legs (October 2014 and June 2015), consisting of 27 lines and 6 tielines, extending up to 40 km from the coast. The line spacing was 1 mile for the main lines and 5-6 miles for the tielines. The bathymetry of the surveyed area varies from very shallow (about 10 m) to near 3000 m. Total field was measured with a G-882 Cesium marine magnetometer of Geometrics (self-oscillating split-beam Cesium vapor), with frequency of acquisition of 10 Hz. Layback was real-time corrected using the acquisition software. Noise was removed by despike in Magpick software (Geometrics), and further processing was done using Oasis montaj (Geosoft) software. Data were subtracted of IGRF values and levelled by tielines to retrieve the final map of anomalies. Several punctual and linear anomalies with varying amplitude and wavenumber were identified, which cannot be explained by bathymetric variation; therefore they must then be due to the presence of higher susceptibility, likely volcanic rocks, and to structural inheritance associated with rifting and Alpine orogeny. The highest anomaly corresponds to the Cabo Raso positive magnetic anomaly, with maximum and minimum of 2800 nT and -1350 nT, respectively. This anomaly, already surveyed in 1958, has been compared to a

    Worldwide energy consumption has risen 30% in the last 25 years. Fossil fuels exploitation is causing depletion of resources and serious environmental problems. Energy efficiency improvement and energy savings are important targets to be achieved on every society as a whole and in residential buildings in particular. In this article, results of a survey and questionnaire on energy consumption and thermal environment held in Kansai area, Japan are reported. Energy savings potential was analyzed for the surveyed 13 houses focusing on certain electrical appliances e.g. TV, rice cooker and refrigerator. Residents' environmental awareness towards energy consumption was clarified through questionnaire. An energy information session towards residents was held, and the resulting changes in lifestyle and their implications on energy consumption were evaluated. (author)

    As part of the VISTA Science Verification programme, a large set of images in Orion was obtained at five near-infrared wavelength bands, from 0.9 to 2.2 μm. The resulting multi-band catalogue contains approximately three million sources, allowing investigation of various issues concerning star and brown dwarf formation, such as a) the difference in the shape of the substellar mass function in a cluster vs. non-clustered environment, b) the influence of massive OB stars on the process of brown dwarf formation, c) the size and morphology of dust envelopes around protostars, and d) the comparative role of mass and environment on the evolution of circumstellar discs. The data from the VISTA Orion Survey, including catalogues, are available to the community. In this article we present an overview of selected science results that have emerged so far from this survey.

    We present an overview and first results of the SOFIA Massive (SOMA) Star Formation Survey, which is using the FORCAST instrument to image massive protostars from $\\sim10$-$40\\:\\rm{\\mu}\\rm{m}$. These wavelengths trace thermal emission from warm dust that in Core Accretion models mainly emerges from the inner regions of protostellar outflow cavities. Dust in dense core envelopes also imprints characteristic extinction patterns at these wavelengths causing intensity peaks to shift along the outflow axis and profiles to become more symmetric at longer wavelengths. We present observational results for the first eight protostars in the survey, i.e., multiwavelength images, including some ancillary ground-based MIR observations and archival Spitzer and Herschel data. These images generally show extended MIR/FIR emission along directions consistent with those of known outflows and with shorter wavelength peak flux positions displaced from the protostar along the blue-shifted, near-facing sides, thus confirming quali...

    Results are presented from an extensive survey of stellar X-ray emission, using the Einstein Observatory. Over 140 stars have been detected to date, throughout the H-R diagram, thus showing that soft X-ray emission is the norm rather than the exception for stars in general. This finding is strongly at odds with pre-Einstein expectations based on standard acoustic theories of coronal heating. Typical examples of stellar X-ray detections and an overview of the survey data are presented. In combination with recent results from solar X-ray observations, the new Einstein data argue for the general applicability of magnetic field-related coronal heating mechanisms.

    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

    Kawasaki disease (KD) has been reported in many countries. However, the incidence of KD in Mongolia is not known. This is the first report of incident cases of KD in Mongolia, which were identified using data from 2 nationwide surveys. Two nationwide retrospective surveys were conducted: medical histories were collected from patients aged 0 to 16 years who were hospitalized countrywide between 1996 and 2008. Hospital records for these patients were also reviewed. Nationwide training seminars on KD were conducted before each survey. For the nationwide surveys, the participation rates among all hospitals with pediatric wards were 97% and 94%. Inpatient medical histories from 1996 through 2008 were reviewed, and, among children younger than 16 years, 9 patients with KD were investigated. The age of KD patients ranged from 1.4 to 14 years; 7 of 9 patients were male. Six (67%) patients fulfilled all 6 clinical diagnostic criteria; the other 3 (33%) were defined as having KD based on the presence of 5 such criteria. Fever persisting 5 or more days, bilateral conjunctival congestion, and changes of the lips and oral cavity were the most common symptoms, and cervical lymphadenopathy was the least common symptom. Cardiac sequelae developed in 5 of the patients, 4 of whom were older than 10 years. The results of these nationwide surveys reveal that KD cases do exist in Mongolia. However, knowledge of KD among Mongolian pediatricians is likely to be poor. Thus, there is a need to augment their understanding to improve management of KD patients. Further studies are crucial to clarify the epidemiologic characteristics of KD in Mongolia.

    To survey all US medical school clerkship directors (CDs) in neurology and to compare results from a similar survey in 2005. A survey was developed by a work group of the American Academy of Neurology Undergraduate Education Subcommittee, and sent to all neurology CDs listed in the American Academy of Neurology database. Comparisons were made to a similar 2005 survey. Survey response rate was 73%. Neurology was required in 93% of responding schools. Duration of clerkships was 4 weeks in 74% and 3 weeks in 11%. Clerkships were taken in the third year in 56%, third or fourth year in 19%, and fourth year in 12%. Clerkship duration in 2012 was slightly shorter than in 2005 (fewer clerkships of ≥4 weeks, p = 0.125), but more clerkships have moved into the third year (fewer neurology clerkships during the fourth year, p = 0.051). Simulation training in lumbar punctures was available at 44% of schools, but only 2% of students attempted lumbar punctures on patients. CDs averaged 20% protected time, but reported that they needed at least 32%. Secretarial full-time equivalent was 0.50 or less in 71% of clerkships. Eighty-five percent of CDs were "very satisfied" or "somewhat satisfied," but more than half experienced "burnout" and 35% had considered relinquishing their role. Trends in neurology undergraduate education since 2005 include shorter clerkships, migration into the third year, and increasing use of technology. CDs are generally satisfied, but report stressors, including inadequate protected time and departmental support. © 2014 American Academy of Neurology.

    Objectives The objectives of this study were to (1) obtain a national perspective of the current state of nursing home (NH) infection prevention and control (IPC) programs and (2) examine differences in IPC program characteristics for NHs that had and had not received an infection control deficiency citation. Design A national cross-sectional survey of randomly sampled NHs was conducted and responses were linked with Certification and Survey Provider Enhanced Reporting (CASPER) and NH Compare data. Setting Surveys were completed and returned by 990 NHs (response rate 39%) between December 2013 and December 2014. Participants The person in charge of the IPC program at each NH completed the survey. Measurements The survey consisted of 34 items related to respondent demographics, IPC program staffing, stability of the workforce, resources and challenges, and resident care and employee processes. Facility characteristics and infection control deficiency citations were assessed using CASPER and NH Compare data. Results Most respondents had at least two responsibilities in addition to those related to infection control (54%) and had no specific IPC training (61%). While many practices and processes were consistent with infection prevention guidelines for NHs, there was wide variation in programs across the US. About 36% of responding facilities had received an infection control deficiency citation. NHs that received citations had infection control professionals with less experience (P = .01) and training (P = .02) and were less likely to provide financial resources for continuing education in infection control (P = .01). Conclusion The findings demonstrate that a lack of adequately trained infection prevention personnel is an important area for improvement. Furthermore, there is a need to identify specific evidence-based practices to reduce infection risk in NHs. PMID:26712489

    Amazon Mechanical Turk was used, for the first time, to collect statistically representative survey data from U.S. households on the presence, number, type and usage of refrigerators, freezers, and various “miscellaneous” refrigeration products (wine/beverage coolers, residential icemakers and non-vapor compression refrigerators and freezers), along with household and demographic information. Such products have been poorly studied to date, with almost no information available about shipments, stocks, capacities, energy use, etc. A total of 9,820 clean survey responses were obtained from four distinct surveys deployed in 2012. General refrigeration product survey responses were weighted to demographics in the U.S. Energy Information Administration’s Residential Energy Consumption Survey 2009 dataset. Miscellaneous refrigeration product survey responses were weighted according to demographics of product ownership found in the general refrigeration product surveys. Model number matching for a portion of miscellaneous refrigeration product responses allowed validation of refrigeration product characteristics, which enabled more accurate estimates of the penetrations of these products in U.S. households. We estimated that there were 12.3±1.0 million wine/beverage coolers, 5.5(–3.5,+3.2) million residential icemakers and 2.9(–2.5,+4.5) million non-vapor compression refrigerators in U.S. households in 2012. (All numerical results are expressed with ranges indicating the 95% confidence interval.) No evidence was found for the existence of non-vapor compression freezers. Moreover, we found that 15% of wine/beverage coolers used vapor compression cooling technology, while 85% used thermoelectric cooling technology, with the vast majority of thermoelectric units having capacities of less than 30 wine bottles (approximately 3.5 cubic feet). No evidence was found for the existence of wine/beverage coolers with absorption cooling technology. Additionally, we estimated

    2014-06-01

    In response to national calls to better align physics laboratory courses with the way physicists engage in research, we have developed an epistemology and expectations survey to assess how students perceive the nature of physics experiments in the contexts of laboratory courses and the professional research laboratory. The Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS) evaluates students' epistemology at the beginning and end of a semester. Students respond to paired questions about how they personally perceive doing experiments in laboratory courses and how they perceive an experimental physicist might respond regarding their research. Also, at the end of the semester, the E-CLASS assesses a third dimension of laboratory instruction, students' reflections on their course's expectations for earning a good grade. By basing survey statements on widely embraced learning goals and common critiques of teaching labs, the E-CLASS serves as an assessment tool for lab courses across the undergraduate curriculum and as a tool for physics education research. We present the development, evidence of validation, and initial formative assessment results from a sample that includes 45 classes at 20 institutions. We also discuss feedback from instructors and reflect on the challenges of large-scale online administration and distribution of results.

    We present results from the first phase of the Seoul National University Bright Quasar Survey in Optical (SNUQSO) as well as its basic observational setup. Previous and current large-area surveys have been successful in identifying many quasars, but they could have missed bright quasars due to their survey design. In order to help complete the census of bright quasars, we have performed spectroscopic observations of new bright quasar candidates selected from various methods based on optical colors, near-infrared colors, radio, and X-ray data. In 2005/2006, we observed 55 bright quasar candidates using the Bohyunsan Optical Echelle Spectrograph (BOES) on the 1.8 m telescope at the Bohyunsan Optical Astronomy Observatory in Korea. We identify 14 quasars/Seyferts from our observation, including an optically bright quasar with i=14.98 mag at z=0.092 (SDSS J003236.59-091026.2). Non-quasar/Seyfert objects are found to be mostly stars, among which there are five M-type stars and one cataclysmic variable. Our result ...

    A new national online survey by Harris Interactive of 1245 hypertensive individuals indicates that >90% were aware that elevated blood pressure (BP) is a major risk factor for cardiovascular disease. The majority discovered that they had elevated BP levels as a result of a routine examination. More than two thirds of persons identified 120/80 mm Hg as an optimal BP level; only 6.0% stated that the Internet was their primary source of information about high BP. More than 60% of respondents had a body mass index >30 kg/m(2), and >50% had other cardiovascular risk factors. More than 50% were involved in some lifestyle change to control BP, and >90% were taking medication. More than 60% reported that BP was controlled (time. The survey results suggest that >90% of hypertensive patients are aware of the risks of elevated BP and that a high percentage of hypertensive patients are being treated with medication. Control rates as reported by respondents were >60% based on last BP recorded; however, between 31% and 40% of patients (based on differences in ethnic groups) were continued on the same therapy despite elevated BP levels. The survey suggests a high degree of risk awareness and treatment, and what appears to be an increase in control rates among hypertensive patients.

    This study provides a summary of the results of an expert opinion survey initiated by the International Society for Traumatic Stress Studies Complex Trauma Task Force regarding best practices for the treatment of complex posttraumatic stress disorder (PTSD). Ratings from a mail-in survey from 25 complex PTSD experts and 25 classic PTSD experts regarding the most appropriate treatment approaches and interventions for complex PTSD were examined for areas of consensus and disagreement. Experts agreed on several aspects of treatment, with 84% endorsing a phase-based or sequenced therapy as the most appropriate treatment approach with interventions tailored to specific symptom sets. First-line interventions matched to specific symptoms included emotion regulation strategies, narration of trauma memory, cognitive restructuring, anxiety and stress management, and interpersonal skills. Meditation and mindfulness interventions were frequently identified as an effective second-line approach for emotional, attentional, and behavioral (e.g., aggression) disturbances. Agreement was not obtained on either the expected course of improvement or on duration of treatment. The survey results provide a strong rationale for conducting research focusing on the relative merits of traditional trauma-focused therapies and sequenced multicomponent approaches applied to different patient populations with a range of symptom profiles. Sustained symptom monitoring during the course of treatment and during extended follow-up would advance knowledge about both the speed and durability of treatment effects.

    This paper is the first of a series describing the results of the Australia Telescope Hubble Deep Field South (ATHDFS) radio survey. The survey was conducted at four wavelengths - 20, 11, 6, and 3 cm, over a 4-year period, and achieves an rms sensitivity of about 10 microJy at each wavelength. We describe the observations and data reduction processes, and present data on radio sources close to the centre of the HDF-S. We discuss in detail the properties of a subset of these sources. The sources include both starburst galaxies and galaxies powered by an active galactic nucleus, and range in redshift from 0.1 to 2.2. Some of them are characterised by unusually high radio-to-optical luminosities, presumably caused by dust extinction.

    The intermediate-mass protostar OMC-2 FIR 4 in Orion is the focus of several ongoing studies, including a CHESS key programme Herschel/HIFI spectral survey. In this poster, we review recent CHESS results on this source, including the properties of the central hot core, the presence of a compact outflow, the spatial variation of the chemical composition, and the discovery of a tenuous foreground cloud. The HIFI spectrum of FIR 4 contains 719 lines from 40 species and isotopologs. Cooling by lines detectable with our sensitivity contributes 2% of the total in the 480 to 1900 GHz range. The total line flux is dominated by CO, followed by H2O and CH3OH. Initial comparisons with spectral surveys of other sources will also be presented.

    To describe health and nutrition status in the elderly population in Mexico. Information from 5,480 adults (>60 years) obtained by the National Health and Nutrition Survey (ENSANUT-2006) was analyzed. Frequencies, means, and confidence intervals at 95% were obtained and adjusted for design effect. Forty percent of the adults reported a lack of social security, 2% suffered from malnutrition, women were affected two times more than men by anemia (34.8 vs. 17%), more than 60% of the population were overweight and had obesity, approximately 25% suffered from hypertension according to the survey, and between 15 and 20% were diabetic. The results of this study show that health and nutrition status among the Mexican elderly population is inadequate. This is a situation that urgently needs to be addressed in order to improve the quality of life of older adults in Mexico.

  5. Perspectives of Speech-Language Pathologists on the Use of Telepractice in Schools: Quantitative Survey Results

    Directory of Open Access Journals (Sweden)

    Janice K. Tucker

    2012-12-01

    Full Text Available This research surveyed 170 school-based speech-language pathologists (SLPs in one northeastern state, with only 1.8% reporting telepractice use in school-settings. These results were consistent with two ASHA surveys (2002; 2011 that reported limited use of telepractice for school-based speech-language pathology. In the present study, willingness to use telepractice was inversely related to age, perhaps because younger members of the profession are more accustomed to using technology.  Overall, respondents were concerned about the validity of assessments administered via telepractice; whether clinicians can adequately establish rapport with clients via telepractice; and if therapy conducted via telepractice can be as effective as in-person speech-language therapy. Most respondents indicated the need to establish procedures and guidelines for school-based telepractice programs.

    Full Text Available Robert Costanza presents four compelling visions of the future, but the language he uses to describe them is emotive and value-laden and may bias the survey results. The descriptions and analogies used may evoke responses from the survey participants that reveal more about their reactions to the description than their attitudes toward a given scenario. It is hypothesized that the use of more neutral language may lead to more support for the scenario involving "self-limited consumption with ample resources" that Costanza calls "Big Government." If this hypothesis is correct, then the skeptic's policy that Costanza appears to prefer has the additional advantage of always leading to the favored outcome, regardless of the state of the world.

    The Work Package 4 of the ORAMED project, a collaborative project (2008-11) supported by the European Commission within its seventh Framework Programme, is concerned with the optimisation of the extremity dosimetry of medical staff in nuclear medicine. To evaluate the extremity doses and dose distributions across the hands of medical staff working in nuclear medicine departments, an extensive measurement programme has been started in 32 nuclear medicine departments in Europe. This was done using a standard protocol recording all relevant information for radiation exposure, i.e. radiation protection devices and tools. This study shows the preliminary results obtained for this measurement campaign. For diagnostic purposes, the two most-used radionuclides were considered: (99m)Tc and (18)F. For therapeutic treatments, Zevalin(®) and DOTATOC (both labelled with (90)Y) were chosen. Large variations of doses were observed across the hands depending on different parameters. Furthermore, this study highlights the importance of the positioning of the extremity dosemeter for a correct estimate of the maximum skin doses.

    We present a tomographic cosmic shear study from the Deep Lens Survey (DLS), which, providing a limiting magnitude {r}{lim}˜ 27 (5σ ), is designed as a precursor Large Synoptic Survey Telescope (LSST) survey with an emphasis on depth. Using five tomographic redshift bins, we study their auto- and cross-correlations to constrain cosmological parameters. We use a luminosity-dependent nonlinear model to account for the astrophysical systematics originating from intrinsic alignments of galaxy shapes. We find that the cosmological leverage of the DLS is among the highest among existing \\gt 10 deg2 cosmic shear surveys. Combining the DLS tomography with the 9 yr results of the Wilkinson Microwave Anisotropy Probe (WMAP9) gives {{{Ω }}}m={0.293}-0.014+0.012, {σ }8={0.833}-0.018+0.011, {H}0={68.6}-1.2+1.4 {\\text{km s}}-1 {{{Mpc}}}-1, and {{{Ω }}}b=0.0475+/- 0.0012 for ΛCDM, reducing the uncertainties of the WMAP9-only constraints by ˜50%. When we do not assume flatness for ΛCDM, we obtain the curvature constraint {{{Ω }}}k=-{0.010}-0.015+0.013 from the DLS+WMAP9 combination, which, however, is not well constrained when WMAP9 is used alone. The dark energy equation-of-state parameter w is tightly constrained when baryonic acoustic oscillation (BAO) data are added, yielding w=-{1.02}-0.09+0.10 with the DLS+WMAP9+BAO joint probe. The addition of supernova constraints further tightens the parameter to w=-1.03+/- 0.03. Our joint constraints are fully consistent with the final Planck results and also with the predictions of a ΛCDM universe.

    Full Text Available Background: International guidelines for the surveillance of breast cancer patients recommend a minimized clinical follow-up including routine history and physical examination and regularly scheduled mammograms. However, the abandonment of scheduled follow-up examinations in breast cancer survivors remains a contradiction to established follow-up guidelines for other solid tumours.Patients and Methods: We report the patients’ view on the basis of a survey performed in two separate geographical areas in Germany. The questionnaires were sent out to 2.658 patients with a history of breast cancer.Results: A total of 801 patients (30.1% responded to the questionnaire. The results of the survey can be summarized in two major categories: First, necessity for surveillance was affi rmed by a majority (>95%, and 47.8% of the organized patients answered that there was a need for more intensive diagnostic effort during follow-up. The main expectation from an intensified follow-up was the increased feeling of security as expressed by >80% of the women. Second, the present survey indicates that most of the regularly scheduled follow-up visits were expanded using extensive laboratory and imaging procedures exceeding the quantity of examinations recommended in the present follow-up guidelines.Conclusion: Despite the fact that only one third of the patients responded to the questionnaire, the survey indicates that a majority of physicians who treated these patients still do not accept the present follow-up guidelines. To some extent this may be explained by the observation that patients and possibly also their doctors trust that intensified follow-up increases diagnostic security and survival. Since considerable changes in the treatment options of breast cancer have been made during the last decades a new trial of investigations in follow-up is warranted.

    Background/Aims Although chronic constipation is a common symptom, to date no international consensus has been reached regarding its definition. The aims of this study were (1) to investigate defecation habits and (2) to examine the prevalence of constipation using the Japanese Society of Internal Medicine (JSIM) and the Rome III criteria using an online survey. Methods An online questionnaire composed of items on the frequency, interval, form of defecation, the management, and self-recognition of constipation (reference standard of constipation) was created. A total of 5155 valid responses were received. In addition, constipation symptoms were evaluated through a survey using the JSIM and the Rome III criteria. Results In the internet survey, 28.4% of the respondents considered themselves to be constipated. Stratified by sex, significantly more females (37.5%) than males (19.1%) considered themselves to be constipated (P < 0.001). The prevalence of constipation among the respondents was 28.0% using the Rome III, but only 10.1% using the JSIM. The diagnostic accuracy was 73.2% for the Rome III and 78.1% for the JSIM, while the diagnostic specificity was 81.1% for the Rome III and 97.5% for the JSIM. However, the diagnostic sensitivities for both measures were low, at 52.2% and 29.2% for the Rome III and the JSIM, respectively. Conclusions The online survey developed for this study was able to provide clarification regarding defecation patterns. The results also suggest a discrepancy between the self-recognized prevalence of constipation in Japan and prevalence of constipation based on the JSIM criteria. PMID:27426278

    Background Cachexia has a high prevalence in cancer patients and negatively impacts prognosis, quality of life (QOL), and tolerance/response to treatments. This study reports the results of three surveys designed to gain insights into cancer cachexia (CC) awareness, understanding, and treatment practices among health care professionals (HCPs). Methods Surveys were conducted globally among HCPs involved in CC management. Topics evaluated included definitions and synonyms of CC, diagnosis and treatment practices, and goals and desired improvements of CC treatment. Results In total, 742 HCPs from 14 different countries participated in the surveys. The majority (97%) of participants were medical oncologists or hematologists. CC was most frequently defined as weight loss (86%) and loss of appetite (46%). The terms loss of weight and decreased appetite (51% and 34%, respectively) were often provided as synonyms of CC. Almost half (46%) of the participants reported diagnosing CC and beginning treatment if a patient experienced a weight loss of 10%. However, 48% of the participants would wait until weight loss was ≥15% to diagnose CC and start treatment. HCPs also reported that 61%–77% of cancer patients do not receive any prescription medication for CC before Stage IV of disease is reached. Ability to promote weight gain was rated as the most important factor for selecting CC treatment. Key goals of treatment included ensuring that patients can cope with the cancer and treatment and have a QOL benefit. HCPs expressed desire for treatments with a more CC-specific mode of action and therapies that enhance QOL. Conclusions These surveys underscore the need for increased awareness among HCPs of CC and its management. PMID:28007753

    A major solar particle event (SPE) may place astronauts at significant risk for the acute radiation syndrome (ARS), which may be exacerbated when combined with other space flight stressors, such that the mission or crew health may be compromised. The National Space Biomedical Research Institute (NSBRI) Center of Acute Radiation Research (CARR) is focused on the assessment of risks of adverse biological effects related to the ARS in animal models exposed to space flight stressors combined with the types of radiation expected during an SPE. As part of this program, FDA-approved drugs that may prevent and/or mitigate ARS symptoms are being evaluated. The CARR studies are focused on the adverse biological effects resulting from exposure to the types of radiation, at the appropriate energies, doses and dose-rates, present during an SPE (and standard reference radiations, gamma rays or electrons). The ARS is a phased syndrome which often includes vomiting and fatigue. Other acute adverse biologic effects of concern are the loss of hematopoietic cells, which can result in compromised bone marrow and immune cell functions. There is also concern for skin damage from high SPE radiation doses, including burns, and resulting immune system dysfunction. Using 3 separate animal model systems (ferrets, mice and pigs), the major ARS biologic endpoints being evaluated are: 1) vomiting/retching and fatigue, 2) hematologic changes (with focus on white blood cells) and immune system changes resulting from exposure to SPE radiation with and without reduced weightbearing conditions, and 3) skin injury and related immune system functions. In all of these areas of research, statistically significant adverse health effects have been observed in animals exposed to SPE-like radiation. Countermeasures for the management of ARS symptoms are being evaluated. New research findings from the past grant year will be discussed.

    The tectonic uplift of South Portugal in the last 5 Million years (My) was firstly identified on the basis of morphologic criteria by Mariano Feio (1952, "The evolution of the relief of Baixo Alentejo and Algarve", transl.). However, the assessment of continental vertical movements off Portugal and its relation with tectonics was only initiated in the 1990-ies. This work was carried out in the framework of FP6 and FP7 in the domains of Natural Hazards funded by the European Community. The swath bathymetry cartography of the southwest part of the Iberian Peninsula resulted from the effort of European and national projects, of 19 oceanographic surveys, a total of 200 ship time days executed from 2000 to 2006, involving 14 research institutions from 7 European countries. As a result of this effort together with acquisition and interpretation of thousands of km of seismic reflection profiles, the Pliocene-Quaternary uplift of the Alentejo continental margin (SW Portugal) is now widely accepted by the scientific community. This uplift has not been yet quantified but it is possible that can have contributed to erosion and deposition of metallic ores as placers in the continental shelf. This argues in favor of the potential existence of placers in the continental shelf and the need for the detailed investigation that will allow determination of ideal location for placers deposition in the past Pliocene-Quaternary (5 My). The source for metals can arguably be associated to the Iberian Pyrite Belt ores hosted in the Alentejo Paleozoic formations and to the hyper-alkaline intrusions of Sines and Monchique of Late Cretaceous age. Artificial renourishment of beaches with offshore sand has not been assessed for the Alentejo littoral, despite that the coast located to the south of the Sines segment shows high susceptibility to erosion. This has been observed on a regular basis as the beaches are frequently devoid of sand, thus jeopardizing their touristic potential. The detailed

    Full Text Available Abstract Background Results from studies of road traffic noise and hypertension are heterogeneous with respect to effect size, effects among males and females and with respect to effects across age groups. Our objective was to further explore these associations. Methods The study used cross-sectional public health survey data from southern Sweden, including 24,238 adults (18 - 80 years old. We used a geographic information system (GIS to assess the average road noise (LAeq 24 hr at the current residential address. Effects on self-reported hypertension were estimated by logistic regression with adjustment for age, sex, BMI, alcohol intake, exercise, education, smoking and socioeconomic status. Results Modest exposure effects (OR ≈ 1.1 were generally noted in intermediate exposure categories (45 -64 dB(A, and with no obvious trend. The effect was more pronounced at > 64 dB(A (OR 1.45, 95% CI 1.04 - 2.02. Age modified the relative effect (p = 0.018. An effect was seen among middle-aged (40 - 59 years old at noise levels 60 - 64 dB(A (OR = 1.27, 95% CI 1.02 - 1.58 and at > 64 dB(A (OR = 1.91, 95% CI 1.19 - 3.06. An effect was also indicated among younger adults but not among elderly. No apparent effect modification by gender, country of origin, disturbed sleep or strained economy was noted. Conclusion The study supports an association between road traffic noise at high average levels and self-reported hypertension in middle-aged. Future studies should use age group -specific relative effect models to account for differences in prevalence.

    Most of the maize silage stored in horizontal silos is exposed to air and can be spoiled by fungi. Potentially toxigenic fungi have been found in maize silage, and about 300 mycotoxins have been detected. Among these mycotoxins, the most harmful for feed and food safety are aflatoxins. The aim of the study was to set up a specific method to detect aflatoxins in maize silage, and to investigate whether aflatoxin contamination in maize silage depends on the level of field contamination of the crop, and whether the occurrence of aerobic spoilage during ensiling has any effect on the final contamination of the silage. A method for the determination of aflatoxin B(1), B(2), G(1) and G(2) in maize silage using high-performance liquid chromagraphy with fluorescence detection has been developed and validated. Recoveries of aflatoxin B(1), B(2), G(1), and G(2) spiked over the 0.25 to 5 µg kg(-1) range averaged 74-94%. The results of laboratory scale and farm scale ensiling experiments indicated that aflatoxins could increase when silage is exposed to air during conservation or during the feed-out phase. The method here proposed to detect aflatoxins in silages has proved to be sensitive and is able to detect levels of 0.1 and 0.5 ng mL(-1) for AFB(1) and AFG(1), and between 0.025 and 0.125 ng mL(-1) for AFB(2) and AFG(2). This study also provides evidence of aflatoxin accumulation in whole crop maize silage as a result of aerobic exposure. Copyright © 2011 Society of Chemical Industry.

    Full Text Available BACKGROUND: In 2006, Spain implemented a national smoke-free legislation that prohibited smoking in enclosed public places and workplaces (except in hospitality venues. In 2011, it was extended to all hospitality venues and selected outdoor areas (hospital campuses, educational centers, and playgrounds. The objective of the study is to evaluate changes in exposure to secondhand smoke among the adult non-smoking population before the first law (2004-05 and after the second law (2011-12. METHODS: Repeated cross-sectional survey (2004-2005 and 2011-2012 of a representative sample of the adult (≥ 16 years non-smoking population in Barcelona, Spain. We assess self-reported exposure to secondhand smoke (at home, the workplace, during leisure time, and in public/private transportation vehicles and salivary cotinine concentration. RESULTS: Overall, the self-reported exposure to secondhand smoke fell from 75.7% (95%CI: 72.6 to 78.8 in 2004-05 to 56.7% (95%CI: 53.4 to 60.0 in 2011-12. Self-reported exposure decreased from 32.5% to 27.6% (-15.1%, p<0.05 in the home, from 42.9% to 37.5% (-12.6%, p=0.11 at work/education venues, from 61.3% to 38.9% (-36.5%, p<0.001 during leisure time, and from 12.3% to 3.7% (-69.9%, p<0.001 in public transportation vehicles. Overall, the geometric mean of the salivary cotinine concentration in adult non-smokers fell by 87.2%, from 0.93 ng/mL at baseline to 0.12 ng/mL after legislation (p<0.001. CONCLUSIONS: Secondhand smoke exposure among non-smokers, assessed both by self-reported exposure and salivary cotinine concentration, decreased after the implementation of a stepwise, comprehensive smoke-free legislation. There was a high reduction in secondhand smoke exposure during leisure time and no displacement of secondhand smoke exposure at home.

    Background Thyroid-stimulating hormone (TSH) is used as the first-line test of thyroid function. Siemens Healthcare Diagnostics recommend that Siemens Centaur reagents must be protected from light in the assay information and on reagent packaging. We have compared the effect of light exposure on results using Siemens TSH-3Ultra and follicle-stimulating hormone reagents. The thyroid-stimulating hormone reagent includes fluoroscein thiocyanate whereas the follicle-stimulating hormone reagent does not. Methods Three levels of quality controls were analysed using SiemensTSH-3Ultra and follicle-stimulating hormone reagent packs that had been kept protected from light or exposed to light at 6-h intervals for 48 h and then at 96 h. Results Thyroid-stimulating hormone results were significantly lower after exposure of TSH-3Ultra reagent packs to light. Results were >15% lower at all three levels of quality control following 18 h of light exposure and continued to decrease until 96 h. There was no significant difference in follicle-stimulating hormone results whether reagents had been exposed to or protected from light. Conclusions Thyroid-stimulating hormone results but not follicle-stimulating hormone results are lowered after exposure of reagent packs to light. Laboratories must ensure that TSH-3Ultra reagents are not exposed to light and analyse quality control samples on every reagent pack to check that there has not been light exposure prior to delivery. The labelling on TSH-3Ultra reagent packs should reflect the significant effect of light exposure compared with the follicle-stimulating hormone reagent. We propose that the effect of light exposure on binding of fluoroscein thiocyanate to the solid phase antibody causes the falsely low results.

    Food safety and food defense are both responsibilities of public health agencies. Food safety practices within restaurants are regulated by state and local public health laws based on the US Food and Drug Administration Model Food Code. However, little is known about preemptive practices against intentional food-borne outbreaks within restaurants. The researchers administered a survey to a 50 percent random sample of South Carolina's restaurants, a state that relies heavily on tourism and the restaurant industry for its economic well-being. The survey received a response rate of 15 percent. The food defense practice items fall under three functional categories: employee management and training practices; vendor and delivery-related practices; and physical facilities and operational security practices. This study presents the results, classified by geographic region. Findings indicate some key areas of vulnerability that need attention to protect the public from mass food outbreaks due to intentional contamination. Of concern, there is much variation in practices by geographic region. On the basis of the survey, recommendations are made to improve restaurant preparedness against food-borne outbreaks from terrorism and malevolent contamination.

    Full Text Available In July of 1931, on the eve of International Polar Year II, an Arctic flight of the Graf Zeppelin rigid airship was organized. This flight was a realization of the idea of F. Nansen, who advocated the use of airships for the scientific exploration of the Arctic territories, which were poorly studied and hardly accessible at that time. The route of the airship flight was Berlin – Leningrad – Arkhangelsk – Franz Josef Land – Severnaya Zemlya – the Taimyr Peninsula – Novaya Zemlya – Arkhangelsk – Berlin. One of scientific goals of the expedition was to measure the H and D geomagnetic field components. Actually, the first aeromagnetic survey was carried out in the Arctic during the flight. After the expedition, only preliminary results of the geomagnetic measurements, in which an anomalous behavior of magnetic declination in the high-latitude part of the route was noted, were published. Our paper is concerned with the first aeromagnetic measurements in the Arctic and their analysis based on archival and modern data on the magnetic field in the Barents and Kara sea regions. It is shown that the magnetic field along the flight route had a complicated structure, which was not reflected in the magnetic charts of those times. The flight was very important for future development of aero- and ground-based magnetic surveys in the Arctic, showing new methods in such surveys.

    Full Text Available Background. The aim of this survey was to describe, in a situation of growing availability of monitoring devices and parameters, the practices in haemodynamic monitoring at the bedside. Methods. We conducted a Web-based survey in Swiss adult ICUs (2009-2010. The questionnaire explored the kind of monitoring used and how the fluid management was addressed. Results. Our survey included 71% of Swiss ICUs. Echocardiography (95%, pulmonary artery catheter (PAC: 85%, and transpulmonary thermodilution (TPTD (82% were the most commonly used. TPTD and PAC were frequently both available, although TPTD was the preferred technique. Echocardiography was widely available (95% but seems to be rarely performed by intensivists themselves. Guidelines for the management of fluid infusion were available in 45% of ICUs. For the prediction of fluid responsiveness, intensivists rely preferentially on dynamic indices or echocardiographic parameters, but static parameters, such as central venous pressure or pulmonary artery occlusion pressure, were still used. Conclusions. In most Swiss ICUs, multiple haemodynamic monitoring devices are available, although TPTD is most commonly used. Despite the usefulness of echocardiography and its large availability, it is not widely performed by Swiss intensivists themselves. Regarding fluid management, several parameters are used without a clear consensus for the optimal method.

    Rural areas of the United States are uniquely vulnerable to the impacts of natural disasters. One possible way to mitigate vulnerability to disasters in rural communities is to have a high-quality hazard mitigation plan in place. To understand the resources available for hazard mitigation planning and determine how well hazard mitigation plans in rural counties meet the needs of vulnerable populations, we surveyed the lead planning or emergency management official responsible for hazard mitigation plans in 96 rural counties in eight states in the Southeastern United States. In most counties, emergency management was responsible for implementing the county's hazard mitigation plan and the majority of counties had experienced a presidentially declared disaster in the last 5 years. Our research findings demonstrated that there were differences in subjective measures of vulnerability (as reported by survey respondents) and objective measures of vulnerability (as determined by US Census data). In addition, although few counties surveyed included outreach to vulnerable groups as a part of their hazard mitigation planning process, a majority felt that their hazard mitigation plan addressed the needs of vulnerable populations "well" or "very well." These differences could result in increased vulnerabilities in rural areas, particularly for certain vulnerable groups.

    Extracorporeal life support (ECLS) is a procedure used to support the failing heart and/or lungs via a heart lung machine. Over 145 institutions perform this practice in the United States with more than 24,000 ECLS cases recorded. While many articles are published each year on common perfusion practice, little information is shared on emerging technologies in ECLS and common practices among perfusionists and ECLS specialists. This article presents our 2006 ECLS survey results and discusses emerging technologies and management topics new to the ECLS arena. ECLS specialists were asked to participate in an online survey. Two hundred twenty-two ECLS specialists responded. This survey suggests positive displacement roller pumps are still the leading pump used for ECLS 122/188 (64.9%). Silicone membrane oxygenators are used by responders 75% of the time for long-term use, while hollow fiber membrane oxygenators are used 44%. Forty-five percent of responders are using heparin or biocoated circuits exclusively, while 14.6% restrict their use to specific subpopulations. The most common coating is heparin coating (67.9%). Activated clotting time (ACT) management is still standard of care for coagulation monitoring (98%), while partial thromboplastin time (PTT) follows at 71.7%. The interquartile range for ACTs is 160-220 seconds and 160-200 seconds with active bleeding. This article suggests ECLS specialists are beginning to incorporate different technology into their practice, such as centrifugal pumps with hollow fiber oxygenators and coated-circuits.

    To reduce bacterial growth and to ensure the quality and safety of food products, the U.S. Department of Agriculture and the U.S. Food and Drug Administration advise consumers to clean their refrigerators regularly, use a refrigerator thermometer, and keep refrigerator temperatures at 40 degrees F (4.4 degrees C) or below. We conducted a nationally representative Web-enabled survey (n = 2,060) to collect data on refrigerator thermometer ownership, home refrigerator temperatures, and the frequency of home refrigerator cleaning. We stratified the sample to provide results for pregnant women, older adults (60 years or older), and the remaining population. About half of all respondents had cleaned their refrigerators at least 1 month before the survey. Only 11% of all respondents had a thermometer in their refrigerator before the survey. Older adults (77.5%) were more likely than the remaining population (70.4%) to have their refrigerators at the recommended temperature (P refrigerator thermometers and to have their refrigerators at a recommended temperature (P refrigerator thermometer were more likely to have their refrigerators at the recommended temperature than were respondents who did not previously own a thermometer (P refrigerated foods at home.

    BACKGROUND AND OBJECTIVE: Adverse effects associated with difficult airway management can be catastrophic and include death, brain injury and myocardial injury. Closed-malpractice claims have shown prolonged and persistent attempts at endotracheal intubation to be the most common situation leading to disastrous respiratory events. To date, there has been no evaluation of the types of difficult airway equipment currently available in Irish departments of emergency medicine. The objective of this survey was to identify the difficult airway equipment available in Irish departments of emergency medicine. METHODS: Departments of emergency medicine in the Republic of Ireland with at least one dedicated Emergency Medicine consultant were surveyed via telephone. RESULTS: All of the departments contacted held at least one alternative device on site for both ventilation and intubation. The most common alternative ventilation device was the laryngeal mask airway (89%). The most common alternative intubating device was the surgical airway device (100%). CONCLUSIONS: Irish departments of emergency medicine compare well with those in the UK and USA, when surveyed concerning difficult airway equipment. However, we believe that this situation could be further improved by training inexperienced healthcare providers in the use of the laryngeal mask airway and intubating laryngeal mask airway, by placing greater emphasis on the ready availability of capnography and by the increased use of portable difficult airway storage units.

    We will present the latest results from a prototype PRV survey with CSHELL. With CSHELL at the NASA Infrared Telescope Facility atop Mauna Kea (R~46,000), we have completed a PRV 2.3 micron survey to detect exoplanets around ~30 red, low mass, and young stars. We are able to reach long-term radial velocity dispersions of ~30 m/s on our survey targets. We are following up candidate RV variables, and have confirmed other previously known RV variables. With a spectral grasp of only 5 nm at 2.3 microns, this performance with CSHELL is limited by detector artifacts, and fringing in the data and flatfields. iSHELL will replace CSHELL at IRTF, with first light expected in May 2016. iSHELL is a 1.15-5.4 micron high spectral resolution (R~70,000) immersion grating, cross-dispersed, white pupil spectrograph. With iSHELL we should be able to obtain a precision of less than 5 m/s in the NIR with iSHELL from the improvements in spectral grasp alone.

    In the last decade, increasing divorce rates, a joint custodial concept, and a deficient legal situation of non-married fathers have been involuntarily provoking cases of a parent with child custody alienating that child in order to exclude the other parent from visitations and educational participation. Medical certificates are frequently of fateful importance in child custody litigation. In an mail survey conduced in six German cities, N = 133 child psychiatrists were asked about the frequency in which they issue such certificates, what certificates contained, what recommendations were made, and where possible the reasons why the other parent was not included in the diagnostic process. According to the results 74.4% of those surveyed were asked to issue such medical certificates at least once in the year prior to the survey; 42% of the psychiatrists stating that the other parent never or only sometimes participated. The symptoms most frequently certified were behavioural disorders (46%), aggression (34%), problems in school/ADD (28%), anxiety (26%), bed-wetting (23%), depression (21%), and psychosomatic reactions (20%). Outlining the characteristics of alienated children and of alienating parents, of "natural" and of "induced" stress-symptoms in children after parental separation, the article provides physicians and institutions of the health system with support to prevent medical certificates being abused in child custody litigation. Some fundamental guidelines are presented as to what aspects and should be explored and which persons referred to before certificates are issued to parents, social workers or judges of family law courts.

    Tests on cyanobacteria communities embedded in cryptobiotic crusts collected in hot and cold deserts on Earth were performed under Mars-like conditions. The simulations were realized as a survey, to find the best samples for future research. During the tests organisms have to resist Mars-like conditions such as atmospheric composition, pressure, variable humidity (saturated and dry conditions) and partly strong UV irradiation. Organisms were tested within their original habitat inside the crust. Nearly half of the cryptobiotic samples from various sites showed survival of a substantial part of their coexisting organisms. The survival in general depended more on the nature of the original habitat and type of the sample than on the different conditions they were exposed to. The best survival was observed in samples from United Arab Emirates (Jebel Ali, 25 km SW of Dubai town) and from Western Australia (near the South edge of Lake Barley), by taxa: Tolypothrix byssoidea, Gloeocapsopsis pleurocapsoides, Nostoc microscopicum, Leptolyngbya or Symploca sp. At both places in salty desert areas members of the Chenopodiaceae family dominated among the higher plants and in the cryptobiotic crust cyanobacterial taxa Tolypothrix was dominant. These organisms were all living in salty locations with dry conditions most of the year. Among them Tolypothrix, Gloeocapsopsis and Symploca sp. were tested in Mars simulation chambers for the first time. The results suggest that extremophiles should be tested with taken into account the context of their original microenvironment, and also the importance to analyse communities of microbes beside single organisms.

    The Mission Accessible Near-Earth Object Survey (MANOS) is a physical characterization survey of Near-Earth Objects (NEOs) to provide physical data for several hundred mission accessible NEOs across visible and near-infrared wavelengths. Using a variety of 1-m to 8-m class telescopes, we observe 5 to 10 newly discovered sub-km NEOs per month in order to derive their rotational properties and taxonomic class.Rotational data can provide useful information about physical properties, like shape, surface heterogeneity/homogeneity, density, internal structure, and internal cohesion. Here, we present results of the MANOS photometric survey for more than 200 NEOs. We report lightcurves from our first three years of observing and show objects with rotational periods from a couple of hours down to a few seconds. MANOS found the three fastest rotators known to date with rotational periods below 20s. A physical interpretation of these ultra-rapid rotators is that they are bound through a combination of cohesive and/or tensile strength rather than gravity. Therefore, these objects are important to understand the internal structure of NEOs. Rotational properties are used for statistical study to constrain overall properties of the NEO population. We also study rotational properties according to size, and dynamical class. Finally, we report a sample of NEOs that are fully characterized (lightcurve and visible spectra) as the most suitable candidates for a future robotic or human mission. Viable mission targets are objects with a rotational period >1h, and a delta-v lower than 12 km/s. Assuming the MANOS rate of object characterization, and the current NEO population estimates by Tricarico (2016), and by Harris and D'Abramo (2015), 10,000 to 1,000,000 NEOs with diameters between 10m and 1km are expected to be mission accessible. We acknowledge funding support from NASA NEOO grant number NNX14AN82G, and NOAO survey program.

    We introduce and provide the scientific motivation for a wide-field photometric and spectroscopic chemodynamical survey of nearby early-type galaxies (ETGs) and their globular cluster (GC) systems. The SAGES Legacy Unifying Globulars and GalaxieS (SLUGGS) survey is being carried out primarily with Subaru/Suprime-Cam and Keck/DEIMOS. The former provides deep gri imaging over a 900 arcmin{sup 2} field-of-view to characterize GC and host galaxy colors and spatial distributions, and to identify spectroscopic targets. The NIR Ca II triplet provides GC line-of-sight velocities and metallicities out to typically ∼8 R {sub e}, and to ∼15 R {sub e} in some cases. New techniques to extract integrated stellar kinematics and metallicities to large radii (∼2-3 R {sub e}) are used in concert with GC data to create two-dimensional (2D) velocity and metallicity maps for comparison with simulations of galaxy formation. The advantages of SLUGGS compared with other, complementary, 2D-chemodynamical surveys are its superior velocity resolution, radial extent, and multiple halo tracers. We describe the sample of 25 nearby ETGs, the selection criteria for galaxies and GCs, the observing strategies, the data reduction techniques, and modeling methods. The survey observations are nearly complete and more than 30 papers have so far been published using SLUGGS data. Here we summarize some initial results, including signatures of two-phase galaxy assembly, evidence for GC metallicity bimodality, and a novel framework for the formation of extended star clusters and ultracompact dwarfs. An integrated overview of current chemodynamical constraints on GC systems points to separate, in situ formation modes at high redshifts for metal-poor and metal-rich GCs.

    2012-02-01

    BACKGROUND AND OBJECTIVE: The last 25 years have seen changes in the management of epidural analgesia for labour, including the advent of low-dose epidural analgesia, the development of new local anaesthetic agents, various regimes for maintaining epidural analgesia and the practice of combined spinal-epidural analgesia. We conducted a survey of Irish obstetric anaesthetists to obtain information regarding the conduct and management of obstetric epidural analgesia in Ireland in 2005. The specific objective of this survey was to discover whether new developments in obstetric anaesthesia have been incorporated into clinical practice. METHODS: A postal survey was sent to all anaesthetists with a clinical commitment for obstetric anaesthesia in the sites approved for training by the College of Anaesthetists, Ireland. RESULTS: Fifty-three per cent of anaesthetists surveyed responded. The majority of anaesthetists (98%) use low-dose epidural analgesia for the maintenance of analgesia. Only 11% use it for test-dosing and 32% for the induction of analgesia. The combined spinal-epidural analgesia method is used by 49%, but two-thirds of those who use it perform fewer than five per month. Patient-controlled epidural analgesia was in use at only one site. CONCLUSION: It appears that Irish obstetric anaesthetists have adopted the low-dose epidural analgesia trend for the maintenance of labour analgesia. This practice is not as widespread, however, for test dosing, the induction of analgesia dose or in the administration of intermittent epidural boluses to maintain analgesia when higher concentrations are used. Since its introduction in 2000, levobupivacaine has become the most popular local anaesthetic agent.

    Background: Bioethics consultations are conducted in varied settings, including hospitals, universities, and other research institutions, but there is sparse information about bioethics consultations conducted in corporate settings such as pharmaceutical companies. The purpose of this article is to describe a bioethics consultation service at a pharmaceutical company, to report characteristics of consultations completed by the service over a 6-year period, and to share results of a consultation feedback survey. Methods: Data on the descriptive characteristics of bioethics consultations were collected from 2008 to 2013 and analyzed in Excel 2007. Categorical data were analyzed via the pivot table function, and time-based variables were analyzed via formulas. The feedback survey was administered to consultation requesters from 2009 to 2012 and also analyzed in Excel 2007. Results: Over the 6-year period, 189 bioethics consultations were conducted. The number of consultations increased from five per year in 2008 to approximately one per week in 2013. During this time, the format of the consultation service was changed from a committee-only approach to a tiered approach (tailored to the needs of the case). The five most frequent topics were informed consent, early termination of a clinical trial, benefits and risks, human biological samples, and patient rights. The feedback survey results suggest the consultation service is well regarded overall and viewed as approachable, helpful, and responsive. Conclusions: Pharmaceutical bioethics consultation is a unique category of bioethics consultation that primarily focuses on pharmaceutical research and development but also touches on aspects of clinical ethics, business ethics, and organizational ethics. Results indicate there is a demand for a tiered bioethics consultation service within this pharmaceutical company and that advice was valued. This company's experience indicates that a bioethics consultation service raises

    Full Text Available Aim: Using the data from graduate surveys, this study aims to analyze which factors related to teaching and learning at the Freiburg Faculty of Medicine can influence study success.Background: Study success and the factors influencing it have long been the subject of investigation, with study success being measured in terms of easily quantifiable indicators (final grades, student satisfaction, etc.. In recent years, it has also frequently been assessed in terms of graduate competency levels. Graduate surveys are considered suitable instruments for measuring these dimensions of study success.Method: Data from three Freiburg graduate surveys conducted one and a half years after graduation were drawn upon for the analysis.Study success was operationalized using four indicators: results on the written section of the M2 exam, self-assessment of medical expertise and scientific expertise, and student satisfaction. Using multiple regression analyses, the predictive power was calculated for selected variables, also measured by the graduate surveys, for the different study success indicators.Results: It was possible to identify models that contribute slightly or moderately to the prediction of study success. The score earned on the university entrance qualification demonstrated itself to be the strongest predictor for forecasting the M2 written exam: R is between 0.08 and 0.22 for the three surveys. Different variables specific to degree program structure and teaching are helpful for predicting medical expertise (R=0.04-0.32 and student satisfaction (R=0.12-0.35. The two variables, and , show themselves to be significant, sample-invariant predictors (β-weight=0.21-0.58, β-weight=0.27-0.56. For scientific expertise, no sample-independent predictors could be determined.Conclusion: Factors describing teaching hardly provide any assistance when predicting the written M2 exam score, which makes sense to the extent that teaching goes far beyond the heavily

    Background Oncology pharmacists are capable of providing medication therapy management (MTM) because of their level of training, practice experiences, and responsibilities. Very little data exist about their current practice, including changing roles in the multidisciplinary team, overall impact, and effects in the education of patients and healthcare professionals. Methods A 70-item survey about oncology pharmacists' activities in oral chemotherapy programs, MTM, and collaborative practice agreements (CPAs) was deployed using a web survey tool (Qualtrics, Provo, UT, USA), targeting pharmacist members of American College of Clinical Pharmacy (ACCP) Hematology/Oncology Practice and Research Network (PRN). The objective of this study was to determine oncology pharmacists' activities in areas of oral chemotherapy programs, MTM, and CPAs. A cross-sectional survey was distributed to the ACCP Hematology/Oncology PRN membership. Investigational Review Board approval was obtained. Results Of the 795 members who were sent the survey, 81 members (10%) responded; 33 respondents (47%) are involved with an oral chemotherapy program; with 42% measuring outcomes of programs. Only six pharmacists (19%) have published or presented their data. A total of 28 (35%) respondents provide MTM services, with almost half (43%) of these MTM services being dictated by CPAs. A small fraction of these pharmacists (21.4%) reported conducting quality assurance evaluations of their MTM services and three pharmacists (10.7%) reported publishing their results. Those pharmacists practicing under CPAs ( n = 28) were surveyed as to activities included in their CPA. The most common activities included adjusting medication, ordering, interpreting, and monitoring lab tests, developing therapeutic plans and educating patients. Reimbursement for providing these services was uncommon: MTM (4%), oral chemotherapy program (6%), and CPA services (11%). Reported obstacles to reimbursement included lack of

    Introduction In view of the debate about occupational factors in Dupuytren’s disease, the aim of this study was to describe the prevalence of the disease in men and its relationship with work exposure, and especially to distinguish heavy manual work with and without significant use of vibrating tools by using data from a surveillance program for musculoskeletal disorders. Method This cross-sectional study was conducted in France between 2002 and 2004. Dupuytren’s disease was diagnosed clinically by one of the 83 occupational physicians involved in the program. Exposure in relation to work status and occupational risk factors was assessed with a self-administered questionnaire, and was categorized according to vibration exposure (defined as use of vibrating tools ≥2h/day), heavy manual work without vibration exposure [defined as use of hand tools ≥2h/day (use of vibrating tools ≥2h/day excluded) and Borg scale ≥15/20] and no form of such exposure. Bivariate and multivariate associations using logistic models were recorded in men and also in those with over 10 years at the same job. Results Of the 2,161 men, 1.3% (n=27) suffered from Dupuytren’s disease (mean age 47.1+/−6.7 years). Heavy manual work without vibration exposure was significantly associated with the disease (adjusted odds ratio - aOR- 3.9[1.3;11.5]) adjusted on age and diabetes), as was the use of vibrating tools (aOR 5.1[2.1;12.2]). These associations remained significant among subjects with over 10 years at the same job, with increases in aOR of 6.1[1.5;25.0] and 10.7[3.4;34.6], respectively. Conclusion Despite the limited number of cases, occupational exposure, including both vibration exposure and heavy manual work without significant vibration exposure, was associated with Dupuytren’s disease.

    Full Text Available The authors assessed sex and age differences in secondhand smoke (SHS exposure among vulnerable adolescent populations. Data from the 2013 Korea Youth Risk Behavior Web-based Survey of 64,499 non-smokers aged 13–18 years were analyzed using multiple logistic regression. Girls were exposed 1.26 times (95% confidence interval, 1.21–1.32 more to home SHS than boys, and the younger adolescents were more likely to be exposed to home SHS than were the older, regardless of sex (p < 0.001. Younger girls living with or without current smokers and the younger boys living with current smokers were more likely to be exposed to SHS at home, when the data were stratified according to current household member smoking, which was one of the main risk factors for SHS exposure at home. Girls living with current smokers were more likely to be exposed to SHS at home than boys regardless age. Girls and younger adolescents, populations vulnerable to smoke exposure, were more likely to be exposed to SHS at home, even though they should be more protected. It is necessary to improve home SHS awareness, especially among these vulnerable populations.

  20. Prenatal low dosage dioxin (TCDD) exposure impairs cochlear function resulting in auditory neuropathy.

    2,3,7,8-tetrachorodibenzo-p-dioxin (TCDD), a ubiquitous and persistent environmental contaminant, is a potent teratogen. Whereas developmental TCDD toxicity is mediated by the aryl hydrocarbon receptor (AhR), the normal function of the AhR is poorly understood. We tested whether dioxin exposure during a critical period of hair cell development disrupts cochlear function in three mouse strains, (C57BL6, BalbC, and CBA) that contain high affinity AhR-b alleles. C57BL/6, BalbC, and CBA dams were exposed to 500 ng/kg TCDD or olive oil (vehicle) on embryonic day 12 by gavage. Cochlear function was analyzed at 1.5 months of age by measuring 1) auditory brainstem response (ABRs) to tone pips from 5.6 to 30 kHz, and 2) distortion-product otoacoustic emissions (DPOAEs) evoked by primaries with f2 at the same frequency values. Cochlear threshold sensitivity following TCDD exposure was significantly elevated in both female and male mice in the C57BL/6 strain, carrying the Ahb-1 allele, but not significantly elevated in the BalbC or CBA strains, carrying the Ahb-2 allele. These ABR threshold deficits in mice carrying the Ahb-1 allele parallels the cleft palate incidence to higher TCDD exposures, suggesting that ABR testing could serve as a sensitive indicator of TCDD toxicity in at-risk children. Moreover, DPOAEs were not affected following TCDD exposure in any of the mouse strains, suggesting that following TCDD exposure mice with the Ahb-1 allele exhibit a mild auditory neuropathy. The causes of many auditory neuropathies are unknown, yet a developmental exposure to dioxin may be a risk factor for this condition.
