    Poverty is widespread and significant in developing countries. As world poverty expands and the gap between rich and poor widens, advocates increasingly support development policies designed to help the poor meet basic needs. Policies generally followed since the second World War have contributed to GNP growth but fail to reduce income inequalities and noticeably improve life for the poor. This paper discusses the evolution of basic needs as a concept and policy goal, the conflict between basic needs and growth, the impact of basic needs on population and popular participation, and results of empirical studies. Basic needs policies may be humanitarian, but evidence supports neither their ability to promote growth, control population, nor encourage popular participation. Basic needs policies are nonetheless noble and challenge us to face poverty as a universal problem.

    Aiming at stable coal supply which occupies an important role as energy substitute for petroleum, as a link in surveys necessary to promote development of coal resources abroad, out of those areas with high reliability as coal resources inside and outside of Japan, by carrying out geophysical exploration and drilling in unexplored districts, a general outline of the overall geological construction and coal bed distribution, etc., can be grasped. This survey has been carried out in FY 1982-1984 in the 2 districts in Kyushu, ARIAKE SEA and OFF NISHI SONOGI and 5 districts in Hokkaido, OFF KUSHIRO, SHINJO,KITA ASHIBETSU, HOKUYO and RUSHIN to verify the coal bed and ascertain distribution conditions. Countinued surveys in these districts so as to grasp the geological construction of the district. Through these surveys, Japanese techniques in coal drilling prospecting, geophysical exploration and data processing have been found useful.

    Full Text Available Abstract Background Due to the low participation in colorectal cancer screening, public preference for colorectal cancer screening modality was determined. Methods A cross-sectional survey was performed of healthy ambulatory adults in a pediatrics primary care office and neighboring church. Overall preference was ranked for each of four colorectal cancer screening modalities: Faecal Occult Blood, Fiberoptic Sigmoidoscopy, Barium Enema and Colonoscopy. Four additional domains of preference also were ranked: suspected discomfort, embarrassment, inconvenience and danger of each exam. Results 80 surveys were analyzed, 57 of which were received from participants who had experienced none of the screening tests. Fecal Occult Blood Testing is significantly preferred over each other screening modality in overall preference and every domain of preference, among all subjects and those who had experienced none of the tests. Conclusions Efforts to increase public participation in colorectal cancer screening may be more effective if undertaken in the context of public perceptions of screening choices.

    We are using screen-based virtual reality landscapes, created using the Unity 3D game engine, to augment the training geoscience students receive in preparing for fieldwork. Students explore these landscapes as they would real ones, interacting with virtual outcrops to collect data, determine location, and map the geology. Skills for conducting field geological surveys - collecting, plotting and interpreting data; time management and decision making - are introduced interactively and intuitively. As with real landscapes, the virtual landscapes are open-ended terrains with embedded data. This means the game does not structure student interaction with the information as it is through experience the student learns the best methods to work successfully and efficiently. These virtual landscapes are not replacements for geological fieldwork rather virtual spaces between classroom and field in which to train and reinforcement essential skills. Importantly, these virtual landscapes offer accessible parallel provision for students unable to visit, or fully partake in visiting, the field. The project has received positive feedback from both staff and students. Results show students find it easier to focus on learning these basic field skills in a classroom, rather than field setting, and make the same mistakes as when learning in the field, validating the realistic nature of the virtual experience and providing opportunity to learn from these mistakes. The approach also saves time, and therefore resources, in the field as basic skills are already embedded. 70% of students report increased confidence with how to map boundaries and 80% have found the virtual training a useful experience. We are also developing landscapes based on real places with 3D photogrammetric outcrops, and a virtual urban landscape in which Engineering Geology students can conduct a site investigation. This project is a collaboration between the University of Leeds and Leeds College of Art, UK, and all

  11. The effect of health literacy on knowledge and receipt of colorectal cancer screening: a survey study

    2007-03-01

    Full Text Available Abstract Background An estimated one-half of Americans have limited health literacy skills. Low literacy has been associated with less receipt of preventive services, but its impact on colorectal cancer (CRC screening is unclear. We sought to determine whether low literacy affects patients' knowledge or receipt of CRC screening. Methods Pilot survey study of patients aged 50 years and older at a large, university-affiliated internal medicine practice. We assessed patients' knowledge and receipt of CRC screening, basic sociodemographic information, and health literacy level. We defined limited literacy as reading below the ninth grade level as determined by the Rapid Estimate of Adult Literacy in Medicine. Bivariate analyses and exact logistic regression were used to determine the association of limited health literacy with knowledge and receipt of CRC screening. Results We approached 105 patients to yield our target sample of 50 completing the survey (recruitment rate 48%. Most subjects were female (72%, African-American (58%, and had household incomes less than $25,000 (87%. Overall, 48% of patients had limited literacy skills (95% CI 35% to 61%. Limited literacy patients were less likely than adequate literacy patients to be able to name or describe any CRC screening test (50% vs. 96%, p Conclusion Patients with limited literacy skills are less likely to be knowledgeable of CRC screening compared to adequate literacy patients. Primary care providers should ensure patients' understanding of CRC screening when discussing screening options. Further research is needed to determine if educating low literacy patients about CRC screening can increase screening rates.

    We investigated the cancer screening rates for five types of cancer (stomach, liver, colorectal, breast, and cervix uteri) using data from the Korean National Cancer Screening Survey (KNCSS), which is a nationwide, annual cross-sectional survey. The eligible study population included cancer-free men 40 years of age and older and women 30 years of age and older. The lifetime screening rate and screening rate with recommendation were calculated. The lifetime screening rates for gastric, liver, colorectal, breast, and cervical cancers were 77.9%, 69.9%, 65.8%, 82.9%, and 77.1%, respectively. The screening rates with recommendation were 70.9%, 21.5%, 44.7%, 70.9%, and 67.9%, respectively. The most common reason for all types of cancer was "no symptoms, " followed by "lack of time" and "fear of the examination procedure. " Efforts to facilitate participation in liver and colorectal cancer screening among Korean men and women are needed.

  13. Pseudo-populations a basic concept in statistical surveys

    CERN Document Server

    Quatember, Andreas

    2015-01-01

    This book emphasizes that artificial or pseudo-populations play an important role in statistical surveys from finite universes in two manners: firstly, the concept of pseudo-populations may substantially improve users’ understanding of various aspects in the sampling theory and survey methodology; an example of this scenario is the Horvitz-Thompson estimator. Secondly, statistical procedures exist in which pseudo-populations actually have to be generated. An example of such a scenario can be found in simulation studies in the field of survey sampling, where close-to-reality pseudo-populations are generated from known sample and population data to form the basis for the simulation process. The chapters focus on estimation methods, sampling techniques, nonresponse, questioning designs and statistical disclosure control.This book is a valuable reference in understanding the importance of the pseudo-population concept and applying it in teaching and research.

    2013-04-01

    Tuberculosis (TB) is a major global health threat. An estimated one-third of the world's population has a history of TB infection, and millions of new infections are occurring every year. The advent of new powerful hardware and software techniques has triggered attempts to develop computer-aided diagnostic systems for TB detection in support of inexpensive mass screening in developing countries. In this paper, we describe the medical background of TB detection in chest X-rays and present a survey of the recent approaches using computer-aided detection. After a thorough research of the computer science literature for such systems or related methods, we were able to identify 16 papers, including our own, written between 1996 and early 2013. These papers show that TB screening is a challenging task and an open research problem. We report on the progress to date and describe experimental screening systems that have been developed.

    This study was conducted to determine the use of screening for stomach, liver, colorectal, breast, and cervical cancers, which are included in the Korean National Cancer Screening Programme. In 2011 the National Cancer Centre in Korea conducted a nationwide, population-based, cross-sectional interview survey using multi-stage random sampling. Participants included 4,100 cancer-free men 40 years and over of age and women over 30 years of age. The lifetime screening rates for stomach, liver, colorectal, breast, and cervical cancers were 76.2%, 54.3%, 56.1%, 79.0%, and, 74.8%, respectively. The rates of recommended screening for stomach, liver, colorectal, breast, and cervical cancers were 64.6%, 22.9%, 35.3%, 60.4%, and 62.4%, respectively. More than 70% of all screening was attributed to organised cancer screening programmes. The main reason given for non attendance was 'no symptoms'. A greater effort is needed to increase screening rates, especially for liver and colorectal cancers.

  16. Basic survey on coal resources in Ariake Sea area

    1984-09-21

    This is a contracted NEDO project. Potential existance of coal resources and geological conditions were studied and the following information was acquired. Area examined is the Ariake Sea area with breadth of 12 km (east to west) and 17 km (north to south) between the Miike Coal Mines and the Karatsu Coal Mines. Investigation was made by a marine drilling (depth being 864.8 m and 865.2 m below the sea bottom) and by a marine seismic method. Existence of coal bed groups comparable with the coal bed in the trial section of the Miike Coal Mines was confirmed by the two-drill trial. This indicates that the west end line of the Miike Coal Mines lies further west of the line connecting the Chikugo barrier and the Minenosu barrier. Investigation by a marine earthquake indicates that the upper surface of the coal beds in the investigated area is distributed in the depth of 400 - 1,100 m below the sea level, and that the basic surface is situated at the depth of 700 - 1,400 m below the sea level. This suggests the possibility that the coal beds of the Miike Coal Mines are distributed to reach the western part of the Ariake Sea. (9 figs, 3 tabs)

  17. Induced Polarization Surveying for Acid Rock Screening in Highway Design

    Highway and pipeline construction agencies have become increasingly vigilant in their efforts to avoid cutting through sulphide-bearing bedrock that has potential to produce acid rock drainage. Blasting and fragmentation of such rock increases the surface area available for sulphide oxidation and hence increases the risk of acid rock drainage unless the rock contains enough natural buffering capacity to neutralize the pH. In December, 2001, the New Brunswick Department of Transportation (NBOT) sponsored a field trial of geophysical surveying in order to assess its suitability as a screening tool for locating near-surface sulphides along proposed highway alignments. The goal was to develop a protocol that would allow existing programs of drilling and geochemical testing to be targeted more effectively, and provide design engineers with the information needed to reduce rock cuts where necessary and dispose of blasted material in a responsible fashion. Induced polarization (IP) was chosen as the primary geophysical method given its ability to detect low-grade disseminated mineralization. The survey was conducted in dipole-dipole mode using an exploration-style time domain IP system, dipoles 8 to 25 m in length, and six potential dipoles for each current dipole location (i.e. n = 1 - 6). Supplementary information was provided by resistivity and VLF-EM surveys sensitive to lateral changes in electrical conductivity, and by magnetic field surveying chosen for its sensitivity to the magnetic susceptibility of pyrrhotite. Geological and geochemical analyses of samples taken from several IP anomalies located along 4.3 line-km of proposed highway confirmed the effectiveness of the screening technique. IP pseudosections from a region of metamorphosed shales and volcaniclastic rocks identified discrete, well-defined mineralized zones. Stronger, overlapping, and more laterally extensive IP anomalies were observed over a section of graphitic and sulphide-bearing metasedimentary

    Full Text Available Abstract Background Cancer screening rates in Korea for five cancer types have increased steadily since 2002. With regard to the life-time cancer screening rates in 2009 according to cancer sites, the second highest was breast cancer (78.1% and the third highest was cervical cancer (76.1%. Despite overall increases in the screening rate, disparities in breast and cervical cancer screening, based on sociodemographic characteristics, still exist. Methods Data from 4,139 women aged 40 to74 years from the 2005 to 2009 Korea National Cancer Screening Survey were used to analyze the relationship between sociodemographic characteristics and receiving mammograms and Pap smears. The main outcome measures were ever having had a mammogram and ever having had a Pap smear. Using these items of information, we classified women into those who had had both types of screening, only one screening type, and neither screening type. We used logistic regression to investigate relationships between screening history and sociodemographic characteristics of the women. Results Being married, having a higher education, a rural residence, and private health insurance were significantly associated with higher rates of breast and cervical cancer screening after adjusting for age and sociodemographic factors. Household income was not significantly associated with mammograms or Pap smears after adjusting for age and sociodemographic factors. Conclusions Disparities in breast and cervical cancer screening associated with low sociodemographic status persist in Korea.

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

    Star formation is arguably the most important physical process in the cosmos. It is a fundamental driver of galaxy evolution and the ultimate source of most of the energy emitted by galaxies. A correct interpretation of star formation rate (SFR) measures is therefore essential to our understanding of galaxy formation and evolution. Unfortunately, however, no single SFR estimator is universally available or even applicable in all circumstances: the numerous galaxies found in deep surveys are often too faint (or too distant) to yield significant detections with most standard SFR measures, and until now there have been no global, multi-band observations of nearby galaxies that span all the conditions under which star-formation is taking place. To address this need in a systematic way, we have undertaken a multi-band survey of all types of star-forming galaxies in the local Universe. This project, the Star Formation Reference Survey (SFRS), is based on a statistically valid sample of 369 nearby galaxies that span...

    1990-07-01

    Insights from the cognitive sciences indicate a continuing need for physicians to understand conceptual knowledge from the basic sciences, despite recent concerns regarding the increasing amount of information in medicine and the growing emphasis on performance skills. A 1987 survey of selected basic science and clinical teachers in North American medical schools was undertaken to identify basic biomedical concepts that are important in the practice of medicine and to specify how difficult these are for students to learn, apply, or both. Responses from faculty (nominated by their deans to answer the survey) from 82% of the medical schools indicated considerable agreement between the basic science teachers and clinical teachers on the relative importance of a set of biomedical concepts, and showed relatively minor levels of disagreement on how difficult these concepts are. The judgments of these teachers could prove extremely useful in (1) determining concepts that--because of their importance--should receive special attention in curriculum efforts, and (2) determining concepts that--because of their difficulty--need "special handling."

    We conducted a tuberculosis (TB) prevalence survey and evaluated the screening methods used in our survey, to assess if screening in TB prevalence surveys could be simplified, and to assess the accuracy of screening algorithms that may be applicable for active case finding. All participants with a positive screen on either a symptom questionnaire, chest radiography (CXR) and/or sputum smear microscopy submitted sputum for culture. HIV status was obtained from prevalent cases. We estimated the accuracy of modified screening strategies with bacteriologically confirmed TB as the gold standard, and compared these with other survey reports. We also assessed whether sequential rather than parallel application of symptom, CXR and HIV screening would substantially reduce the number of participants requiring CXR and/or sputum culture. Presence of any abnormality on CXR had 94% (95%CI 88-98) sensitivity (92% in HIV-infected and 100% in HIV-uninfected) and 73% (95%CI 68-77) specificity. Symptom screening combinations had significantly lower sensitivity than CXR except for 'any TB symptom' which had 90% (95%CI 84-95) sensitivity (96% in HIV-infected and 82% in HIV-uninfected) and 32% (95%CI 30-34) specificity. Smear microscopy did not yield additional suspects, thus the combined symptom/CXR screen applied in the survey had 100% (95%CI 97-100) sensitivity. Specificity was 65% (95%CI 61-68). Sequential application of first a symptom screen for 'any symptom', followed by CXR-evaluation and different suspect criteria depending on HIV status would result in the largest reduction of the need for CXR and sputum culture, approximately 36%, but would underestimate prevalence by 11%. CXR screening alone had higher accuracy compared to symptom screening alone. Combined CXR and symptom screening had the highest sensitivity and remains important for suspect identification in TB prevalence surveys in settings where bacteriological sputum examination of all participants is not feasible.

    Socioeconomic disparities in colorectal and breast cancer screening persist, partially accounting for disparities in cancer outcomes. Some neighborhood characteristics--particularly area level socioeconomic factors--have been linked to cancer screening behavior, but few studies have examined the relationship between perceived neighborhood quality and screening behavior, which may provide more insight into the ways in which neighborhood environments shape cancer related behaviors. This study examines the relationship between several aspects of the perceived neighborhood environment and breast and colorectal cancer screening behavior among a population-based sample of Wisconsin residents. A sub-goal was to compare the relevance of different perceived neighborhood factors for different screening tests. This is a cross-sectional study of 2008-2012 data from the Survey of the Health of Wisconsin, a population-based annual survey of Wisconsin residents. An average risk sample of Black, Hispanic and White women age 50 and older (n = 1265) were selected. Survey regression analyses examined predictors of screening, as well as adherence to screening guidelines. Models controlled for individual socio-demographic information and insurance status. Perceptions of social and physical disorder, including fear of crime and visible garbage, were associated with screening rates. Findings emphasize the particular importance of these factors for colorectal cancer screening, indicating the necessity of improving screening rates in areas characterized by social disorganization, crime, and physical disorder. Additional work should be done to further investigate the pathways that explain the linkage between neighborhood conditions, perceived neighborhood risks and cancer screening behavior.

    As part of the Basic Science Survey Series (BSSS) for Dentistry, members of the American Dental Education Association (ADEA) Physiology, Pharmacology, and Therapeutics Section surveyed course directors of basic pharmacology courses in North American dental schools. The survey was designed to assess, among other things, faculty affiliation and experience of course directors, teaching methods, general course content and emphasis, extent of interdisciplinary (shared) instruction, and impact of recent curricular changes. Responses were received from forty-nine of sixty-seven (73.1 percent) U.S. and Canadian dental schools. The findings suggest the following: 1) substantial variation exists in instructional hours, faculty affiliation, placement within curriculum, class size, and interdisciplinary nature of pharmacology courses; 2) pharmacology course content emphasis is similar among schools; 3) the number of contact hours in pharmacology has remained stable over the past three decades; 4) recent curricular changes were often directed towards enhancing the integrative and clinically relevant aspects of pharmacology instruction; and 5) a trend toward innovative content delivery, such as use of computer-assisted instruction applications, is evident. Data, derived from this study, may be useful to pharmacology course directors, curriculum committees, and other dental educators with an interest in integrative and interprofessional education.

    Full Text Available Abstract Background Professional medical organizations recommend individualized patient decision making about prostate cancer screening. Little is known about primary care physicians' use of pre-screening discussions to promote informed decision making for prostate cancer screening. The aim of this study is to explore physicians' use of pre-screening discussions and reasons why physicians would or would not try to persuade patients to be screened if they initially refuse testing. Methods Primary care physicians completed a self-administered survey about prostate cancer screening practices for informed decision making. Results Sixty-six physicians (75.9% completed the survey, and 63 were used in the analysis. Thirteen physicians (20.6% reported not using prescreening discussions, 45 (71.4% reported the use of prescreening discussions, and 3 (4.8% reported neither ordering the PSA test nor discussing it with patients. Sixty-nine percent of physicians who reported not having discussions indicated they were more likely to screen African American patients for prostate cancer, compared to 50% of physicians who reported the use of discussions (Chi-square(1 = 1.62, p = .20. Similarly, 91% of physicians who reported not having discussions indicated they are more likely to screen patients with a family history of prostate cancer, compared to 46% of those who reported the use of discussion (Chi-square(1 = 13.27, p Conclusion Although guidelines recommend discussing the risks and benefits of prostate cancer screening, physicians report varying practice styles. Future research needs to consider the nature of discussions and the degree to which informed decision making is being achieved in clinical practice.

    O’Neill, MB

    2017-06-01

    This study was undertaken to evaluate uncertainty from the Basic Specialist Trainee perspective. The survey of trainees explored 1) factors in decision making, 2) the personal impact of uncertainty, 3) the responses to both clinical errors and challenges to their decision making and 4) the potential strategies to address uncertainty. Forty-one (93%) of trainees surveyed responded. Important factors in decision making were clinical knowledge and senior colleague’s opinion. Sixty percent experienced significant anxiety post call as a consequence of their uncertainty. When errors are made by colleagues, the trainee’s response is acceptance (52.5%), and sympathy (32%).Trainees are strongly influenced by the opinions of senior colleagues often changing their opinions having made confident decisions. Solutions to address uncertainty include enhanced knowledge translation, and to a lesser extent, enhanced personal awareness and resilience awareness. To enhance the training experience for BST and lessen the uncertainty experienced these strategies need to be enacted within the training milieu.

    The purpose of this study was to determine how North American dental students are taught neuroscience during their preclinical dental education. This survey represents one part of a larger research project, the Basic Science Survey Series for Dentistry, which covers all of the biomedical science coursework required of preclinical students in North American dental schools. Members of the Section on Anatomical Sciences of the American Dental Education Association assembled, distributed, and analyzed the neuroscience survey, which had a 98.5 percent response from course directors of the sixty-seven North American dental schools. The eighteen-item instrument collected demographic data on the course directors, information on the content in each course, and information on how neuroscience content is presented. Findings indicate that 1) most neuroscience instruction is conducted by non-dental school faculty members; 2) large content variability exists between programs; and 3) an increase in didactic instruction, integrated curricula, and use of computer-aided instruction is occurring. It is anticipated that the information derived from the survey will help guide neuroscience curricula in dental schools and aid in identifying appropriate content.

    Create a screening measure of health literacy for use with the Health Information National Trends Survey (HINTS). Participants completed a paper-based survey. Items from the survey were used to construct a health literacy screening measure. A population-based survey conducted in geographic areas of high and low minority frequency and in Central Appalachia. Two thousand nine hundred four English-speaking participants were included in this study: 66% white, 93% completed high school, mean age = 52.53 years (SD = 16.24). A health literacy screening measure was created using four items included in the HINTS survey. Scores could range from 0 (no questions affirmative/correct) to 4 (all questions answered affirmatively/correctly). Multiple regression analysis was used to determine whether demographic variables known to predict health literacy were indeed associated with the constructed health literacy screening measure. The weighted average health literacy score was 2.63 (SD = 1.00). Those who were nonwhite (p = .0005), were older (p literacy screening measure scores. This study highlights the need to assess health literacy in national surveys, but also serves as evidence that screening measures can be created within existing datasets to give researchers the ability to consider the impact of health literacy. © The Author(s) 2016.

    AIM: To identity the factors influencing colorectal cancer (CRC) screening behavior and willingness among Chinese outpatients. METHODS: An outpatient-based face-to-face survey was conducted from August 18 to September 7, 2010 in Changhai Hospital. A total of 1200 consecutive patients aged ≥ 18 years were recruited for interview. The patient's knowledge about CRC and screening was pre-measured as a predictor variable, and other predictors included age, gender, educational level, monthly household income and health insurance status. The relationship between these predictors and screening behavior, screening willingness and screening approach were examined using Pearson's χ2 test and logistic regression analyses. RESULTS: Of these outpatients, 22.5% had undergone CRC screening prior to this study. Patients who had participated in the screening were more likely to have good knowledge about CRC and screening (OR: 5.299, 95% CI: 3.415-8.223), have health insurance (OR: 1.996, 95% CI: 1.426-2.794) and older in age. Higher income, however, was found to be a barrier to the screening (OR: 0.633, 95% CI: 0.467-0.858). An analysis of screening willingness showed that 37.5% of the patients would voluntarily participated in a screen at the recommended age, but 41.3% would do so under doctor's advice. Screening willingness was positively correlated with the patient's knowledge status. Patients with higher knowledge levels would like to participate in the screening (OR: 4.352, 95% CI: 3.008-6.298), and they would select colonoscopy as a screening approach (OR: 3.513, 95% CI: 2.290-5.389). However, higher income level was, again, a barrier to colonoscopic screening (OR: 0.667, 95% CI: 0.505-0.908). CONCLUSION: Patient's level of knowledge and income should be taken into consideration when conducting a feasible CRC screening.

    2014-06-01

    As part of the Basic Science Survey Series for Dentistry, members of the American Dental Education Association (ADEA) Physiology, Pharmacology, and Therapeutics Section surveyed directors of physiology courses in North American dental schools. The survey was designed to assess, among other things, faculty affiliation and experience of course directors, teaching methods, general course content and emphasis, extent of interdisciplinary (shared) instruction, and impact of recent curricular changes. Responses were received from forty-four of sixty-seven (65.7 percent) U.S. and Canadian dental schools. The findings suggest the following: substantial variation exists in instructional hours, faculty affiliation, class size, and interdisciplinary nature of physiology courses; physiology course content emphasis is similar between schools; student contact hours in physiology, which have remained relatively stable in the past fifteen years, are starting to be reduced; recent curricular changes have often been directed towards enhancing the integrative and clinically relevant aspects of physiology instruction; and a trend toward innovative content delivery, such as use of computer-assisted instruction, is evident. Data from this study may be useful to physiology course directors, curriculum committees, and other dental educators with an interest in integrative and interprofessional education.

    As part of the Basic Science Survey Series (BSSS) for Dentistry, members of the American Dental Education Association (ADEA) Anatomical Sciences Section surveyed faculty members teaching embryology and histology courses at North American dental schools. The survey was designed to assess, among other things, curriculum content, utilization of laboratories, use of computer-assisted instruction (CAI), and recent curricular changes. Responses were received from fifty-nine (88.1 percent) of the sixty-seven U.S. and Canadian dental schools. Findings suggest the following: 1) a trend toward combining courses is evident, though the integration was predominantly discipline-based; 2) embryology is rarely taught as a stand-alone course, as content is often covered in gross anatomy, oral histology, and/or in an integrated curriculum; 3) the number of contact hours in histology is decreasing; 4) a trend toward reduction in formal laboratory sessions, particularly in embryology, is ongoing; and 5) use of CAI tools, including virtual microscopy, in both embryology and histology has increased. Additionally, embryology and histology content topic emphasis is identified within this study. Data, derived from this study, may be useful to new instructors, curriculum and test construction committees, and colleagues in the anatomical sciences, especially when determining a foundational knowledge base.

    Basic scientific research generates knowledge that has intrinsic value which is independent of future applications. Basic research may also lead to practical benefits, such as a new drug or diagnostic method.  Building on our previous study of basic biomedical and biological researchers at Harvard, we present findings from a new survey of similar scientists from three countries.  This survey asked about the scientists' motivations, goals and perspectives along with their attitudes concerning  policies designed to increase both the practical (i.e. public health) benefits of basic research as well as their own personal satisfaction. Close to 900 basic investigators responded to the survey; results corroborate the main findings from the previous survey of Harvard scientists.  In addition, we find that most bioscientists disfavor present policies that require a discussion of the public health potential of their proposals in grants but generally favor softer policies aimed at increasing the quality of work and the potential practical benefits of basic research. In particular, bioscientists are generally supportive of those policies entailing the organization of more meetings between scientists and the general public, the organization of more academic discussion about the role of scientists in the society, and the implementation of a "basic bibliography" for each new approved drug.

    Full Text Available Abstract Background Intimate partner violence (IPV is a human rights violation that is pervasive worldwide, and is particularly critical for women during the reproductive period. IPV includes physical, sexual and emotional abuse. Nurses on in-patient postpartum units are well-positioned to screen women for IPV, yet low screening rates suggest that barriers to screening exist. The purpose of this study was to (a identify the frequency of screening for IPV, (b the most important barriers to screening, (c the relationship between the barriers to screening and the frequency of screening for types of abuse, and (d to identify other factors that contribute to the frequency of screening for IPV. Methods In 2008, we conducted a cross-sectional survey of 96 nurses from postpartum inpatient units in three Canadian urban hospitals. The survey included the Barriers to Abuse Assessment Tool (BAAT, adapted for postpartum nurses (PPN. Ordinary least squares (OLS regression models were used to predict barriers to screening for each type of IPV. Results The frequency of screening varied by the type of abuse with highest screening rates found for physical and emotional abuse. According to the BAAT-PPN, lack of knowledge was the most important barrier to screening. The BAAT-PPN total score was negatively correlated with screening for physical, sexual, and emotional abuse. Using OLS regression models and after controlling for demographic characteristics, the BAAT-PPN explained 14%, 12%, and 11% of the variance in screening for physical, sexual and emotional abuse, respectively. Fluency in the language of the patient was negatively correlated with screening for each type of abuse. When added as Step 3 to OLS regression models, language fluency was associated with an additional decrease in the likelihood of screening for physical (beta coefficient = -.38, P P = .05, and emotional abuse (beta coefficient = -.48, P Conclusions Our findings support an inverse

    Transgender men are less likely than cisgender women to receive cervical cancer screening. The purpose of the current study was to understand experiences with and preferences for cervical cancer screening among transgender men. Ninety-one transgender men ages 21-63 completed the survey. The survey evaluated experiences with and preferences for screening, including opinions regarding human papillomavirus (HPV) self-sampling as a primary cervical cancer screening. Half (50.5%) of participants did not have Pap smear screening within the past 3 years. The majority (57.1%) of participants preferred HPV self-sampling over provider-collected Pap smear screening. Participants who reported discrimination were more likely to prefer HPV self-sampling (odds ratio = 3.29, 95% confidence interval 1.38-7.84, P = 0.007). Primary HPV testing via HPV self-sampling may improve cervical cancer screening uptake among transgender men. Future work should pilot this innovative cervical cancer screening method within this population.

    2009-10-01

    To survey American College of Occupational and Environmental Medicine (ACOEM) members regarding recent consensus guidelines for screening commercial drivers for Obstructive Sleep Apnea (OSA). A brief survey instrument was distributed electronically by the American College of Occupational and Environmental Medicine to its members during February 2008 to April 2008. Most (92%) of the 552 examiners opined that screening commercial drivers for OSA was important. Nevertheless, only 42% reported screening using consensus guidelines or another specific protocol. Common reasons for not applying the guidelines included unaware (36%), too complicated (12%), client retention (10%), and driver inconvenience (10%). Most would consider using the guidelines going forward but 39% wanted additional evidence and another 21% only if they became the "community standard." More education regarding OSA and drivers is needed. A Federal mandate and eliminating "doctor shopping" would likely increase examiners' compliance with screening.

    2013-01-01

    OBJECTIVE Prior research indicates CT colonography (CTC) would be a cost-effective colorectal cancer (CRC) screening test if widespread availability were to increase overall CRC screening adherence rates. The primary aims of this multicenter study were to evaluate patient experience and satisfaction with CTC screening and compare preference against screening colonoscopy. MATERIALS AND METHODS A 12-question survey instrument measuring pretest choice, experience, and satisfaction was given to a consecutive cohort of adults undergoing CTC screening in three disparate screening settings: university academic center, military medical center, and community practice. The study cohort was composed of individuals voluntarily participating in clinical CTC screening programs. RESULTS A total of 1417 patients responded to the survey. The top reasons for choosing CTC for screening included “noninvasiveness” (68.0%), “avoidance of sedation/anesthesia” (63.1%), “ability to drive after the test” (49.2%), “avoidance of optical colonoscopy risks” (46.9%), and “identifying abnormalities outside the colon” (43.3%). Only 7.2% of patients reported pain during the CTC examination and only 2.5% reported greater than moderate discomfort. Of 441 patients who had experienced both CTC and optical colonoscopy, 77.1% preferred CTC and 13.8% preferred optical colonoscopy. Of all patients, 29.6% indicated that they may not have undergone optical colonoscopy screening if CTC were not available. Of all patients, 92.9% labeled their overall experience with CTC as “excellent” or “good,” and 93.0% indicated they would choose CTC for their next screening. CONCLUSION Respondents reported a very high satisfaction level with CTC, and those who had experienced both modalities indicated a preference for CTC over optical colonoscopy. These results suggest that CTC has the potential to increase adherence to CRC screening guidelines if widely available. PMID:22623549

    Agilent GC-MS MSD Chemstation offers automated library search report for toxicological screening using total ion chromatogram (TIC) and mass spectroscopy in normal mode. Numerous peaks appear in the chromatogram of biological specimen such as blood or urine and often large migrating peaks obscure small target peaks, in addition, any target peaks of low abundance regularly give wrong library search result or low matching score. As a result, retention time and mass spectrum of all the peaks in the chromatogram have to be checked to see if they are relevant. These repeated actions are very tedious and time-consuming to toxicologists. MSD Chemstation software operates using a number of macro files which give commands and instructions on how to work on and extract data from the chromatogram and spectroscopy. These macro files are developed by the own compiler of the software. All the original macro files can be modified and new macro files can be added to the original software by users. To get more accurate results with more convenient method and to save time for data analysis, we developed new macro files for reports generation and inserted new menus in the Enhanced Data Analysis program. Toxicological screening reports generated by these new macro files are in text mode or graphic mode and these reports can be generated with three different automated subtraction options. Text reports have Brief mode and Full mode and graphic reports have the option with or without mass spectrum mode. Matched mass spectrum and matching score for detected compounds are printed in reports by modified library searching modules. We have also developed an independent application program named DrugMan. This program manages drug groups, lists and parameters that are in use in MSD Chemstation. The incorporation of DrugMan with modified macro modules provides a powerful tool for toxicological screening and save a lot of valuable time on toxicological work.

    2016-03-01

    Virtual screening, the search for bioactive compounds via computational methods, provides a wide range of opportunities to speed up drug development and reduce the associated risks and costs. While virtual screening is already a standard practice in pharmaceutical companies, its applications in preclinical academic research still remain under-exploited, in spite of an increasing availability of dedicated free databases and software tools. In this survey, an overview of recent developments in this field is presented, focusing on free software and data repositories for screening as alternatives to their commercial counterparts, and outlining how available resources can be interlinked into a comprehensive virtual screening pipeline using typical academic computing facilities. Finally, to facilitate the set-up of corresponding pipelines, a downloadable software system is provided, using platform virtualization to integrate pre-installed screening tools and scripts for reproducible application across different operating systems.

  9. Shale oil specialty markets: Screening survey for United States applications

    Energy Technology Data Exchange (ETDEWEB)

    1987-12-01

    EG and G requested J. E. Sinor Consultants Inc. to carry out an initial screening study on the possibilities for producing specialty chemicals from oil shale. Raw shale oil is not an acceptable feedstock to refineries and there are not enough user of heavy fuel oil in the western oil shale region to provide a dependable market. The only alternatives are to hydrotreat the oil, or else ship it long distances to a larger market area. Either of these alternatives results in a cost penalty of several dollars per barrel. Instead of attempting to enter the large-volume petroleum products market, it was hypothesized that a small shale oil facility might be able to produce specialty chemicals with a high enough average value to absorb the high costs of shipping small quantities to distant markets and still provide a higher netback to the plant site than sales to the conventional petroleum products market. This approach, rather than attempting to refine shale oil or to modify its characteristics to satisfy the specifications for petroleum feedstocks or products, focuses instead on those particular characteristics which distinguish shale oil from petroleum, and attempts to identify applications which would justify a premium value for those distinctive characteristics. Because byproducts or specialty chemicals production has been a prominent feature of oil shale industries which have flourished for periods of time in various countries, a brief review of those industries provides a starting point for this study. 9 figs., 32 tabs.

  10. Illustrative presentation of some basic concepts of network internal reliability with comments as regards engineering surveys

    Prószyński, Witold

    2016-06-01

    The paper integrates some earlier and the recent findings of the author in the area of network internal reliability and presents a consistent system of concepts in this respect. The concepts of outlier detection and outlier identification linked directly with the global model test and the outlier tests respectively, are shown as a basis for the concepts such as outlier detectability and outlier identifiability. Also, a four level classification of gross errors expressed in a form of a tree-diagram is presented including perceptible and imperceptible errors, detectable and undetectable errors and identifiable and unidentifiable errors. Their properties are given mainly in a descriptive way, deliberately limiting rigorous mathematical formulas to a necessary minimum. Understanding of different types of gross errors is useful in analyzing the results of the outlier detection and identification procedures as well as in designing the networks to make them duly robust to observation gross errors. It is of special importance for engineering surveys where quite often low-redundancy networks are used. Main objective of the paper is to demonstrate a clear and consistent system of basic concepts related to network internal reliability.

    2017-05-01

    United Nation's Sustainable Development Goals and the World Health Organization's Global Monitoring Framework support a strong global commitment to reducing the high burden of cervical and breast cancers among low- and middle-income countries. Strategies include vaccination, screening, and early diagnosis. Population-based surveys, such as those conducted by the Demographic and Health Surveys (DHS) Program, can collect the information needed to guide cancer control efforts in a standardized comparable manner. We identified and evaluated the breadth of breast and cervical cancer screening information that was collected by the DHS from 1984 through 2015. Then, we determined if these surveys currently provide the specific and measurable data about both the quantity and quality of cancer screening needed to guide national efforts to reduce the overall effects of cervical and breast cancers. We searched the DHS website to identify surveys conducted between the start of the DHS Program in 1984 and November 2015 that included questions about breast and cervical cancer screening. The relevant questions were extracted from the questionnaire, translated into English, and grouped by themes. Of the 90 countries where DHS surveys have been implemented, cervical cancer screening questions were included in 22 countries (24.4%) and breast cancer screening questions in 18 countries (20.0%). The common themes identified were disease knowledge, screening knowledge, screening practice, and screening outcomes. Most countries with survey questionnaires available for review addressed at least one aspect of screening practice (88.9% of cervical and 87.5% of breast), although few countries queried knowledge and outcomes. Questions that assess varied aspects of breast and cervical cancer screening have been incorporated into relatively few DHS surveys. The themes identified could guide the design of a standard set of questions for use in future population-based surveys and enable evaluation

    A DNA aptamer based high-performance affinity chromatography is developed for selective extraction and screening of a basic protein lysozyme. First, a poly(glycidyl methacrylate-co-ethylene dimethacrylate) monolithic column was synthesized in situ by thermally initiated radical polymerization, and then an anti-lysozyme DNA aptamer was covalently immobilized on the surface of the monolith through a 16-atom spacer arm. The target protein lysozyme but non-target proteins can be trapped by the immobilized anti-lysozyme DNA aptamer. In contrast, lysozyme cannot be trapped by the immobilized oligodeoxynucleotide that does not contain the sequence of the anti-lysozyme DNA aptamer. The study clearly demonstrates the trapping of lysozyme by the immobilized anti-lysozyme DNA aptamer is mainly due to specific recognition rather than simple electrostatic interaction of positively charged protein and the negatively charged DNA. The inter-day precision was determined as 0.8% for migration time and 4.2% for peak area, respectively. By the use of aptamer affinity monolith, a screening strategy is developed to selectively extract lysozyme from chicken egg white, showing the advantages of high efficiency, low cost and ease-of-operation.

    Full Text Available Background: Internationally, breast cancer comprises 29% of all cancer incidences. In Greece, 1,500-1,800women die annually from breast cancer out of the 4,000 who are affected. Only 5% are detected at an early diseasestage through mammography screening.Aim: This paper presents findings from a study exploring the factors that influence Greek women’smammography screening behaviour.Methodology: Data were collected in Athens-Greece, during the period March-July 2008, from individuals whowere members of six women’s associations. One hundred and eighty six questionnaires were completed and 33interviews were conducted from a sub-sample. This paper reports the findings from the questionnaire survey.Results: Participants had a variety of demographic characteristics with 85% of them having attendedmammography screening. Only 61% of them intended to continue in the future. Τhe majority of women agreedwith a number of factors which supported their decision to participate in regular mammography screening, such asdoctors’ encouragement and mammogram efficacy to detect breast cancer at an early stage, while anxiety wasidentified as a possible inhibitor to their participation.Conclusion: Women’s mammography screening behaviour and perceptions of mammography screening appearedto be positive in relation to their participation. However, the reasons as to why a large number of women indicatedthey were unlikely to go for mammography screening again is not known, and needs further investigation.

    Colorectal cancer (CRC) screening rates are often ascertained via self-reports but can be subject to overreporting bias. Asking about intention to get screened before asking about past screening may minimize overreporting of cancer screening. In a statewide survey conducted from July through October of 2005, we embedded an experiment that tested the effect of question ordering (asking about future intention to get screened before or after asking about past screening; "future first" and "future second," respectively), crossed with survey mode (mail versus telephone), on CRC screening rates. Weighted analysis focused on 752 respondents who were ages 50 years or older. We found (a) that asking about future intentions to get screened before asking about past screening (future first) statistically significantly lowers reports of past CRC screening [70.9% future second versus 58.0% future first; odds ratio (OR), 1.83; 95% confidence interval (95% CI), 1.08-3.13]; (b) that there was no main effect of survey mode; and (c) that the effect of the ordering of the future intentions item varies by survey mode. In the mailed survey, the odds of reporting past CRC screening were almost thrice greater in the future second condition compared with the future first condition (72.4% versus 49.0%, respectively; OR, 2.74; 95% CI, 1.22-6.17). In the telephone condition, the odds of reporting were only 28% higher in the future second (69.5%) condition than in the future first condition (63.9%; OR, 1.28; 95% CI, 0.64-2.57). The results suggest that asking about future intentions to get screened before the actual behavior elicits lower, and arguably more truthful reports of CRC screening but mainly in mailed surveys.

    Full Text Available Aims: To evaluate the prevailing practices for proper screening and referral scheme among Indian pediatricians for retinopathy of prematurity (ROP. Materials and Methods: Pediatricians registered with Indian Academy of Pediatrics from six states of India were selected randomly and were telephonically interviewed in accordance with a preformed questionnaire which comprised of questions regarding demographic factors, number of premature children seen per month, awareness and referral scheme to ophthalmologist; responses thus obtained were analyzed. Results: Hundred percent knowledge about ROP and need for screening in premature babies was observed among the respondents. However, only 135 (58% pediatricians always referred for ROP screening, 19 (8% referred only sometimes and 80 (34% did not refer at all. Consistent referral protocols taking into account all plausible risk factors for ROP were followed by only 25% of those who always referred. Major deterrent in ROP screening was perceived as non-availability of trained ophthalmologists. Conclusions: Only 14.5% of total pediatricians contacted were following international recommendations for ROP referral. Screening for ROP remains dismal as observed in this pilot survey as a consequence of non-availability of trained ophthalmologists as well as inconsistent screening guidelines.

    Full Text Available Background Prostate cancer is the most common cancer among men and the second leading cause of deaths from cancer. Results of previous studies indicate the effectiveness of screening and early detection in reducing mortality from this disease. Objectives The purpose of this study was to survey the knowledge about prostate cancer and perceived barriers to prostate cancer screening among medical staff of two universities in Ahvaz, Iran. Materials and Methods This cross-sectional descriptive study was performed on 120 employees over 40 years old at Ahvaz Jundishapur University of Medical Sciences and Shahid Chamran University of Ahvaz, who were selected by using simple random sampling. The data collection tool was a researcher-created questionnaire based on the study of texts and other studies. Data analysis was performed using SPSS software and through analytical methods including descriptive and inferential statistics. Results The most common barriers to screening for prostate cancer were a lack of knowledge about where to go for tests and how screening tests are done (70.8%, a lack of emphasis on screening tests (59.1%, and a fear of thinking about the disease (50%. Results showed that there was no significant relationship between doing the serum antigen test and having knowledge regarding prostate cancer. But there was a significant association between prostate cancer screening and perceived barriers (P = 0.001. Conclusions Results showed that whereas knowledge by itself cannot guarantee men’s participation in prostate cancer screenings, perceived barriers can play an important role in discouraging men from cancer screening participation. Therefore, designing programs to address these barriers is very important.

    Full Text Available Abstract Background The incidence of colorectal cancer can be decreased by appropriate use of screening modalities. Patients with a family history of colon cancer and of African-American ethnicity are known to be at higher risk of developing colorectal cancer. We aimed to determine if there is a lack of physician knowledge for colorectal cancer screening guidelines based on family history and ethnicity. Between February and April 2009 an anonymous web-based survey was administered to a random sample selected from a national list of 25,000 internists, family physicians and gastroenterologists. A stratified sampling strategy was used to include practitioners from states with high as well as low CRC incidence. All data analyses were performed following data collection in 2009. Results The average knowledge score was 37 ± 18% among the 512 respondents. Gastroenterologists averaged higher scores compared to internists, and family physicians, p = 0.001. Only 28% of physicians correctly identified the screening initiation point for African-Americans while only 12% of physicians correctly identified the screening initiation point and interval for a patient with a family history of CRC. The most commonly cited barriers to referring high-risk patients for CRC screening were "patient refusal" and "lack of insurance reimbursement." Conclusions There is a lack of knowledge amongst physicians of the screening guidelines for high-risk populations, based on family history and ethnicity. Educational programs to improve physician knowledge and to reduce perceived barriers to CRC screening are warranted to address health disparities in colorectal cancer.

    Maternal hypothyroidism in pregnancy is associated with several adverse outcomes. The American Thyroid Association and the Endocrine Society Guidelines for the management of thyroid diseases in pregnancy were published in 2011 and 2012, respectively; however, impact of the guidelines in routine clinical practice is unknown. We therefore carried out a survey to study current practices in the screening and management of hypothyroidism in pregnancy. We collected completed questionnaire survey based on clinical case scenarios from 321 members of the Asia-Oceania Thyrpid Association (AOTA). Responses from 310 clinician members (from 21 Asian countries) were analyzed. For a woman with hypothyroidism planning pregnancy, 54% favored testing thyroid function before adjusting the dose, whilst 32% recommended increasing the dose of L-thyroxine (L-T₄) as soon as pregnancy is confirmed. For a pregnant woman with newly diagnosed overt hypothyroidism, most responders initiated a full dose of L-T₄. One half of responders used serum TSH and free T₄ to monitor the dose of L-T₄. Although the target of thyroid function tests that responders aimed to achieve with L-T₄ was inconsistent, but a majority aim to keep TSH within recommended trimester specific range. Twenty-one % responders or their institutions screened all pregnant women for thyroid dysfunction, 66% performed targeted screening of only the high-risk group, whilst 13% did not carry out systemic screening. Majority of responders practices within recommendations of major professional societies; however, there is wide variation in the clinical practice in the treatment and screening of hypothyroidism during pregnancy in Asia.

    Full Text Available This study was performed to identify factors associated with screening for diabetic retinopathy and nephropathy. Data from the Korean National Health and Nutrition Examination Survey between 2007 and 2009 were analyzed. Of 24,871 participants, 1,288 patients diagnosed with diabetes at ≥30 years of age were included. 36.3% received screening for diabetic retinopathy, and 40.5% received screening for diabetic nephropathy during the previous year. Patients living in rural areas, those with less education, those who had not received education about diabetes care, and those who did not receive medical care for diabetes were screened less often for retinopathy or nephropathy. Patients with poorer self-reported health status were screened more often. Occupation, smoking status, and diabetes duration were associated with retinopathy screening. Lower family income was associated with decreased nephropathy screening. Receiving education about diabetes care and receiving medical care for diabetes were significant factors in patients with a shorter duration of diabetes (the significant odds ratio [OR] of not receiving education varied between 0.27 and 0.51, and that of not receiving medical care varied between 0.34 and 0.42. Sociodemographic factors and health-related factors as well as education and medical care influenced screening for diabetic complications among those with a longer duration of diabetes (for retinopathy and nephropathy, the significant OR of living in a rural area varied between 0.56 and 0.61; for retinopathy, the significant OR of current smokers was 0.55, and the p-trend of subjective health status was <0.001; for nephropathy, the significant OR of a monthly household income of <3000 dollars was 0.61 and the p-trends of education and subjective health status were 0.030 and 0.007, respectively. Efforts to decrease sociodemographic disparities should be combined with education about diabetes care to increase the screening, especially

    Full Text Available Abstract Background Liver cancer is one of most commonly diagnosed cancers among Koreans. Chronic hepatitis B virus (HBV infection is a major risk factor for liver cancer. HBV infection can be prevented by effective screening and vaccination programs. The purpose of this study is to examine the status of HBV infection and the predictors associated with HBV vaccination. Methods The study population was derived from the 2005 Korea National Cancer Screening Survey (KNCSS. The KNCSS is an annual cross-sectional survey that uses a nationally-representative random sampling to investigate cancer screening rates. A total of 1,786 Koreans over 40 years of age participated in this study. Results Of all the participants, 5.9% reported HBV positive (HBsAg+, HBsAb-, 41.8% were HBV negative but protected (HBsAg-, HBsAb+, and 52.3% were unprotected (HBsAg-, HBsAb-. Among unprotected individuals (n = 934, 23.1% reported to have received the vaccination. About half of those who had vaccinations completed the 3-shot vaccine series. In multiple analyses, education, having private cancer insurance, alcohol use, having regular check-up, and doing regular exercise were associated with completed HBV vaccination. Conclusion This study result suggests that we need a liver cancer education program to increase HBV awareness and to increase the liver cancer prevention message among low educated populations.

    Full Text Available Screening for atrial fibrillation (AF in primary care has been recommended; however, the views of healthcare professionals (HCPs are not known. This study aimed to determine the opinions of HCP about the feasibility of implementing screening within a primary care setting.A cross-sectional mixed methods census survey of 418 HCPs from 59 inner-city practices (Nottingham, UK was conducted between October-December 2014. Postal and web-surveys ascertained data on existing methods, knowledge, skills, attitudes, barriers and facilitators to AF screening using Likert scale and open-ended questions. Responses, categorized according to HCP group, were summarized using proportions, adjusting for clustering by practice, with 95% C.Is and free-text responses using thematic analysis.At least one General Practitioner (GP responded from 48 (81% practices. There were 212/418 (51% respondents; 118/229 GPs, 67/129 nurses [50 practice nurses; 17 Nurse Practitioners (NPs], 27/60 healthcare assistants (HCAs. 39/48 (81% practices had an ECG machine and diagnosed AF in-house. Non-GP HCPs reported having less knowledge about ECG interpretation, diagnosing and treating AF than GPs. A greater proportion of non-GP HCPs reported they would benefit from ECG training specifically for AF diagnosis than GPs [proportion (95% CI GPs: 11.9% (6.8-20.0; HCAs: 37.0% (21.7-55.5; nurses: 44.0% (30.0-59.0; NPs 41.2% (21.9-63.7]. Barriers included time, workload and capacity to undertake screening activities, although training to diagnose and manage AF was a required facilitator.Inner-city general practices were found to have adequate access to resources for AF screening. There is enthusiasm by non-GP HCPs to up-skill in the diagnosis and management of AF and they may have a role in future AF screening. However, organisational barriers, such as lack of time, staff and capacity, should be overcome for AF screening to be feasibly implemented within primary care.

    Obesity is associated with poor breast cancer (BC) prognosis. Larger tumor size and more advanced disease stage at diagnosis could partly explain this outcome and nonadherence of obese women to BC screening may play a role. We examined the relationship between BMI (kg/m) and the use of mammography in Switzerland as well as separately in the German-speaking part with mainly opportunistic screening and in the French-speaking part with organized programs. We analyzed the data of 50-69-year-old women (n=3121) of the Swiss Health Survey 2012. Study participants were classified as underweight (BMIself-perceived health. In Switzerland, 47% of women aged 50-69 years had had BC screening within the last 2 years, 35% of women in the German-speaking and 78% of women in the French-speaking part. In the total group, mammography use was higher in overweight than in normal-weight women (adjusted odds ratio 1.21, 95% confidence interval 0.98-1.49). Stratified by region, this effect was only maintained in women of the German-speaking part (adjusted odds ratio 1.41, 95% confidence interval 1.08-1.85; P-interactionspeaking part, overweight women even attended mammography screening more often than normal-weight women.

    Office tracking, scheduling, and reminder systems have been shown to improve utilization of screening mammography, but little is known about the use of these systems by primary care physicians. We surveyed 132 primary care and obstetrics and gynecology practices affiliated with an independent practice association model health maintenance organization in central Massachusetts to determine their use of reminder, scheduling, and follow-up systems, and education and counseling services aimed at increasing screening mammography rates. The use of chart flags to remind physicians of a patient's need for mammography screening was reported by 30% of practices. Thirty-one percent reported the use of flow sheets, and 27% reported the use of mail or telephone patient reminders. At least one of these three systems was used by 57% of the practices, whereas 43% reported having none of these three systems. Variations in the use of these office systems were related to specialty type, physician number, and clinical staffing. The majority of practices (77%) reported using written educational materials, and 42% offered prevention counseling with nonphysician staff. Very few offices (8%) reported using mail or telephone reminders for previously scheduled appointments. Despite the proven effectiveness of reminder systems for screening mammography, many practices do not have a system in place. Promotion of reminder systems in primary care practices could have a substantial impact on mammography utilization.

    The aim of this article is to identify factors affecting access to breast cancer screening in Mexico according to the sociodemographic characteristics of the women, using three nationally-representative surveys. Descriptive statistics were performed and multiple classification analysis techniques were used. The dependent variables were that the women had realized: 1) breast self-examination, 2) clinical breast examination, or 3) mammography; the covariates were: age group, education level, type of locality (urban/rural), marital status, number of children, enrollment in social security and socioeconomic status. A low level of screening use was detected and gaps were observed between different groups of women according to sociodemographic characteristics. In general women of lower economic strata, without enrollment in social security and with lower educational levels, showed fewer detection practices than the national average.

    Full Text Available Clinical and research laboratory employees have to face various hazards and biological risk factors in the working environment due to laboratory structures and regulations. In order to protect personnelfrom these occupational hazards and laboratory acquired infections, basic microbiological practices which are the major factors of biosafety concept should be well known, appropriate and safe laboratory equipments (primary barriers should be used and functional working areas (secondary barriers should be designed. We have limited data regarding biosafety profiles of the laboratories and laboratory staff in our country. Nevertheless, in the light of the existing studies, it is thought that technical and infrastructural facilities are inadequate and also biosafety levels and related applications are either not well known or not properly carried out by the staff. Implementing theoretically accepted basic microbiological practices, a certain quality and cosciousness level of the staff, continuous in-service training are important factors of a safe and efficient working environment in the laboratories.

    Objective To investigate the awareness and use of the Systematic Review Center for Laboratory Animal Experimentation’s (SYRCLE) risk-of-bias tool, the Animal Research: Reporting of In Vivo Experiments (ARRIVE) reporting guidelines, and Gold Standard Publication Checklist (GSPC) in China in basic medical researchers of animal experimental studies. Methods A national questionnaire-based survey targeting basic medical researchers was carried in China to investigate the basic information and awareness of SYRCLE’s risk of bias tool, ARRIVE guidelines, GSPC, and animal experimental bias risk control factors. The EpiData3.1 software was used for data entry, and Microsoft Excel 2013 was used for statistical analysis in this study. The number of cases (n) and percentage (%) of classified information were statistically described, and the comparison between groups (i.e., current students vs. research staff) was performed using chi-square test. Results A total of 298 questionnaires were distributed, and 272 responses were received, which included 266 valid questionnaires (from 118 current students and 148 research staff). Among the 266 survey participants, only 15.8% was aware of the SYRCLE’s risk of bias tool, with significant difference between the two groups (P = 0.003), and the awareness rates of ARRIVE guidelines and GSPC were only 9.4% and 9.0%, respectively; 58.6% survey participants believed that the reports of animal experimental studies in Chinese literature were inadequate, with significant difference between the two groups (P = 0.004). In addition, only approximately 1/3 of the survey participants had read systematic reviews and meta-analysis reports of animal experimental studies; only 16/266 (6.0%) had carried out/participated in and 11/266 (4.1%) had published systematic reviews/meta-analysis of animal experimental studies. Conclusions The awareness and use rates of SYRCLE’s risk-of-bias tool, the ARRIVE guidelines, and the GSPC were low among Chinese

    To describe the degree of diffusion and acceptance of national guideline on screening and diagnosis of gestational diabetes (GDM) among Italian diabetes centers and to detect possible areas for benchmarking. In 2013 the Italian Diabetes in Pregnancy Study Group structured a national survey, focused on GDM screening and diagnostic procedures, that was administered to diabetologists. Overall, 122 diabetologists of 122 different diabetes centers (21.7% territorial, 78.3% hospital/University) completed the questionnaire. All respondents declared to execute a 75 g-oral glucose tolerance test (OGTT) as diagnostic test. Almost one in five centers preferred a universal screening procedure, the others executing a selective risk factors-based screening. In patients at high risk for GDM the OGTT was performed at 16-18 weeks' gestation in 84.0% of the cases; only 6.5% of respondents preferred to execute it as soon as possible; and 9.5% used to wait until 24-28 weeks' gestation. In the case of fasting plasma glucose (FPG) ≥ 5.1 mmol/l (92 mg/dl), two third of respondents used to proceed with the execution of the complete diagnostic OGTT, the others considering sufficient the FPG value for the diagnosis. Good level of reception of national recommendations was documented. The diagnostic procedure was generally accepted and applied. Some criticisms were specifically linked to the choice of universal or risk factor-based screening procedure, and to the right time for executing the OGTT in women at high risk.

    For the purpose of evaluating coal resource in the Kalewa area southwest of Sagaing about 300km northwest of Mandalay city, Myanmar, survey was conducted on geology, test boring, specimen analysis, infrastructure, etc. The range of geological survey is approximately 5.5km{sup 2}, and test boring was carried out for 9 holes (total length: 2,046.74m). For the coal analysis, 8 specimens were used, and measurement was made of the combustion calorie, sulfur content, water content, density, ash, ash melting temperature, etc. Survey was also conducted on drilling conditions/methods for coal mines in the periphery, roads for coal transportation, barge loading ports, etc. The results of the survey are as follows. The thickness of the minable main coal seam is 2.1-2.9m, and the inclination angle is 40-42 degrees. Specimens from coal seams indicate low ash, low sulfur content and high combustion calorie. The estimated coal reserves are 7,730,000 tons, and they total 15,300,000 tons including those from other coal seams. In the development by the 100m-width longwall mining which was proposed, it is possible to produce 130,000 tons/year for more than 20 years. (NEDO)

    Full Text Available Eye-tracking studies on exploration of faces and objects in autism provided important knowledge but only in a constraint condition (chin rest, total time looking at screen not reported, without studying potential differences between subjects with autism spectrum disorder (ASD and controls in spontaneous visual attention toward a screen presenting these stimuli. This study used eye tracking to compare spontaneous visual attention to a screen displaying a face or an object between children with autism and controls in a nonconstraint condition and to investigate the relationship with clinical characteristics in autism group. Time exploring screen was measured during passive viewing of static images of faces or objects. Autistic behaviors were assessed by the CARS and the BSE-R in autism group. In autism group, time exploring face screen and time exploring object screen were lower than in controls and were not correlated with degree of distractibility. There was no interaction between group and type of image on time spent exploring screen. Only time exploring face screen was correlated with autism severity and gaze impairment. Results highlight particularities of spontaneous visual attention toward a screen displaying faces or objects in autism, which should be taken into account in future eye-tracking studies on face exploration.

    Full Text Available The study of alcohol abuse is relatively new in Brazil. Government estimates suggest that 11.2% of the Brazilian population is alcohol dependent. Problems associated with alcohol dependence include domestic violence, increased risk of traffic accidents, poor self-esteem and weak academic performance. A factor known to correlate with alcohol abuse in 12-17 year olds is to have the money necessary to purchase alcoholic beverages. No data is available, however, on the price of alcoholic beverages. The objective of the present study was to provide data on price and to compare the price of alcoholic beverages to basic food items in the Brazilian diet. We also had interest in studying a population in the northeast region of Brazil. This region is the poorest in Brazil, has the highest percentage of alcohol dependency and is seldom the focus of research on dependency. We report that the prices of many alcoholic beverages are less than the price of basic food items. Prices of alcoholic beverages including beer, wine and spirits were compared to the prices of select food items as represented in the Food Pyramid. Food items were selected from the categories of Grain, Dairy, Fruit, Meat and Vegetable. Data was gathered from 32 supermarkets in 8 cities in the northeast state of Paraiba. The price of alcohol is generally less expensive than most basic food group items, especially brands of cachaça (a spirit distilled from sugar cane and beer. Data on price should be considered in any alcohol dependency program in Brazil.

    Comorbidity at the time of diagnosis is an independent prognostic factor for survival among women suffering from cervical or breast cancer. Although cancer screening practices have proven their efficacy for mortality reduction, little is known about adherence to screening recommendations for women suffering from chronic conditions. We investigated the association between eleven chronic conditions and adherence to cervical and breast cancer screening recommendations in France. Using data from a cross-sectional national health survey conducted in 2008, we analyzed screening participation taking into account self-reported: inflammatory systemic disease, cancer, cardiovascular disease, chronic respiratory disease, depression, diabetes, dyslipidemia, hypertension, obesity, osteoarthritis and thyroid disorders. We first computed age-standardized screening rates among women who reported each condition. We then estimated the effect of having reported each condition on adherence to screening recommendations in logistic regression models, with adjustment for sociodemographic characteristics, socioeconomic position, health behaviours, healthcare access and healthcare use. Finally, we investigated the association between chronic conditions and opportunistic versus organized breast cancer screening using multinomial logistic regression. The analyses were conducted among 4226 women for cervical cancer screening and 2056 women for breast cancer screening. Most conditions studied were not associated with screening participation. Adherence to cervical cancer screening recommendations was higher for cancer survivors (OR = 1.73 [0.98-3.05]) and lower for obese women (OR = 0.73 [0.57-0.93]), when accounting for our complete range of screening determinants. Women reporting chronic respiratory disease or diabetes participated less in cervical cancer screening, except when adjusting for socioeconomic characteristics. Adherence to breast cancer screening recommendations was lower for

    To examine the relationship between cervical screening uptake and political engagement, and to test whether political engagement and voting behaviour mediate the association between age and cervical screening uptake. A population-based survey of women in England in 2010. Women aged 26-64 took part in home-based computer-assisted interviews (n = 890). Women were classified as 'up to date' or 'overdue/never been screened' for cervical screening. Most women (81%) were up-to-date with screening; 19% were overdue. Age and marital status were associated with screening status. Women who were not registered to vote, had not voted in previous general elections, and those who showed less interest in elections and lower intention to engage in political activities were more likely to be overdue for screening. In multivariate analyses (adjusting for all significant measures) 'being on the electoral register' was the only significant independent predictor of screening status. 'Being on the electoral register' was also the only measure of voting behaviour that mediated the association between age and screening status. We found limited evidence for the hypothesis that falling attendance for cervical screening could be associated with a broader phenomenon of disillusionment as indexed by reported voting behaviour and other measures of political engagement. Alternative explanations should be considered in order to better understand falling cervical screening uptake, particularly among younger women.

    To explore perceptions, barriers and patterns of social media (SM) use among rheumatology fellows and basic scientists. An online survey was disseminated via Twitter, Facebook and by email to members of the Emerging European League Against Rheumatism Network. Questions focused on general demographics, frequency and types of SM use, reasons and barriers to SM use. Of 233 respondents (47 countries), 72% were aged 30-39 years, 66% female. 83% were active users of at least one SM platform and 71% were using SM professionally. The majority used SM for communicating with friends/colleagues (79%), news updates (76%), entertainment (69%), clinical (50%) and research (48%) updates. Facebook was the dominant platform used (91%). SM was reported to be used for information (81%); for expanding professional networks (76%); new resources (59%); learning new skills (47%) and establishing a professional online presence (46%). 30% of non-SM users justified not using SM due to lack of knowledge. There was a substantial use of SM by rheumatologists and basic scientists for social and professional reasons. The survey highlights a need for providing learning resources and increasing awareness of the use of SM. This could enhance communication, participation and collaborative work, enabling its more widespread use in a professional manner. Published by the BMJ Publishing Group Limited.

    Despite health education efforts to educate women on breast cancer and breast cancer screening modalities, the incidence of breast cancer and presentation at an advanced stage are still a problem in Malaysia. To determine factors associated with the uptake of breast cancer screening among women in the general population. This pre-intervention survey was conducted in a suburban district. All households were approached and women aged 20 to 60 years old were interviewed with pre-tested guided questionnaires. Variables collected included socio-demographic characteristics, knowledge on breast cancer and screening practice of breast cancer. Univariate and multivariate analysis were performed. 41.5% of a total of 381 respondents scored above average; the mean knowledge score on causes and risks factors of breast cancer was 3.41 out of 5 (SD1.609). 58.5% had ever practiced BSE with 32.5% performing it at regular monthly intervals. Uptake of CBE by nurses and by doctors was 40.7% and 37.3%, respectively. Mammogram uptake was 14.6%. Significant predictors of BSE were good knowledge of breast cancer (OR=2.654, 95% CI: 1.033-6.816), being married (OR=2.213, 95% CI: 1.201-4.076) and attending CBE (OR=1.729, 95% CI: 1.122-2.665). Significant predictors for CBE included being married (OR=2.161, 95% CI: 1.174-3.979), good knowledge of breast cancer (OR=2.286, 95% CI: 1.012-5.161), and social support for breast cancer screening (OR=2.312, 95% CI: 1.245-4.293). Women who had CBE were more likely to undergo mammographic screening of the breast (OR=5.744, 95% CI: 2.112-15.623), p<0.005. CBE attendance is a strong factor in promoting BSE and mammography, educating women on the importance of breast cancer screening and on how to conduct BSE. The currently opportunistic conduct of CBE should be extended to active calling of women for CBE.

    Full Text Available Abstract Background This study sought to describe stroke prevalence in Spanish elderly populations and compare it against that of other European countries. Methods We identified screening surveys -both published and unpublished- in Spanish populations, which fulfilled specific quality requirements and targeted prevalence of stroke in populations aged 70 years and over. Surveys covering seven geographically different populations with prevalence years in the period 1991–2002 were selected, and the respective authors were then asked to provide descriptions of the methodology and raw age-specific data by completing a questionnaire. In addition, five reported screening surveys in European populations furnished useful data for comparison purposes. Prevalence data were combined, using direct adjustment and logistic regression. Results The overall study population, resident in central and north-eastern Spain, totalled 10,647 persons and yielded 715 cases. Age-adjusted prevalences, using the European standard population, were 7.3% for men, 5.6% for women, and 6.4% for both sexes. Prevalence was significantly lower in women, OR 0.79 95% CI 0.68–0.93, increased with age, particularly among women, and displayed a threefold spatial variation with statistically significant differences. Prevalences were highest, 8.7%, in suburban, and lowest, 3.8%, in rural populations. Compared to pooled Spanish populations, statistically significant differences were seen in eight Italian populations, OR 1.39 95%CI (1.18–1.64, and in Kungsholmen, Sweden, OR 0.40 95%CI (0.27–0.58. Conclusion Prevalence in central and north-eastern Spain is higher in males and in suburban areas, and displays a threefold geographic variation, with women constituting the majority of elderly stroke sufferers. Compared to reported European data, stroke prevalence in Spain can be said to be medium and presents similar age- and sex-specific traits.

  1. A survey of the clinical acceptability of screening for postnatal depression in depressed and non-depressed women

    2006-08-01

    Full Text Available Abstract Background Information on clinical acceptability is needed when making cost-utility decisions about health screening implementation. Despite being in use for two decades, most data on the clinical acceptability of the Edinburgh Postnatal Depression Scale (EPDS come from qualitative reports, or include relatively small samples of depressed women. This study aimed to measure acceptability in a survey of a relatively large, community sample with a high representation of clinically depressed women. Methods Using mail, telephone and face-to-face interview, 920 postnatal women were approached to take part in a survey on the acceptability of the EPDS, including 601 women who had screened positive for depression and 245 who had received DSM-IV diagnoses of depression. Acceptability was measured on a 5-point Likert scale of comfort ranging from "Not Comfortable", through "Comfortable" to "Very Comfortable". Results The response rate was just over half for postal surveys (52% and was 100% for telephone and face-to-face surveys (432, 21 and 26 respondents for postal, telephone and face-to-face surveys respectively making 479 respondents in total. Of these, 81.2% indicated that screening with the EPDS had been in the range of "Comfortable" to "Very Comfortable". The other 18.8 % rated screening below the "Comfortable" point, including a small fraction (4.3% who rated answering questions on the EPDS as "Not Comfortable" at the extreme end of the scale. Comfort was inversely related to EPDS score, but the absolute size of this effect was small. Almost all respondents (97% felt that screening was desirable. Conclusion The EPDS had good acceptability in this study for depressed and non-depressed women. Women's views on the desirability of postnatal depression screening appear to be largely independent of personal level of comfort with screening. These results should be useful to policy-makers and are broadly supportive of the Edinburgh Postnatal

    The gravity survey is applied to model a ground structure. For this purpose, a spring-type relative gravimeter is usually used. Though this type of gravimeter can provide very accurate data, it is very expensive and difficult to handle. This means that a simple and inexpensive sensor to measure the gravity is required. For this, we began to develop a new gravimeter using a force-balanced-type accelerometer. In this study, we develop a preliminary system and calibrate it. Then, a simple measurements is carried out on an observation wheel, on a car, and on a ship. The gravity data is contaminated by vibration of carriers, though we found a technique of blind source separation can be hopeful to pick up gravity data from the observed data. However, we also recognized some problems that needs to be solved.

    Full Text Available The giant panda (Ailuropoda melanoleuca is a critically endangered mammalian species. Studies on functions of regulatory proteins involved in developmental processes would facilitate understanding of specific behavior in giant panda. The basic helix-loop-helix (bHLH proteins play essential roles in a wide range of developmental processes in higher organisms. bHLH family members have been identified in over 20 organisms, including fruit fly, zebrafish, mouse and human. Our present study identified 107 bHLH family members being encoded in giant panda genome. Phylogenetic analyses revealed that they belong to 44 bHLH families with 46, 25, 15, 4, 11 and 3 members in group A, B, C, D, E and F, respectively, while the remaining 3 members were assigned into "orphan". Compared to mouse, the giant panda does not encode seven bHLH proteins namely Beta3a, Mesp2, Sclerax, S-Myc, Hes5 (or Hes6, EBF4 and Orphan 1. These results provide useful background information for future studies on structure and function of bHLH proteins in the regulation of giant panda development.

    Although they are the main constituents of the Galactic disk population, for half of the open clusters in the Milky Way reported in the literature nothing is known except the raw position and an approximate size. The main goal of this study is to determine a full set of uniform spatial, structural, kinematic, and astrophysical parameters for as many known open clusters as possible. On the basis of stellar data from PPMXL and 2MASS, we used a dedicated data-processing pipeline to determine kinematic and photometric membership probabilities for stars in a cluster region. For an input list of 3784 targets from the literature, we confirm that 3006 are real objects, the vast majority of them are open clusters, but associations and globular clusters are also present. For each confirmed object we determined the exact position of the cluster centre, the apparent size, proper motion, distance, colour excess, and age. For about 1500 clusters, these basic astrophysical parameters have been determined for the first time....

    Background and aims The aim of this study was to test the screening properties of several combinations of items from gambling scales, in order to harmonize screening of gambling problems in epidemiological surveys. The objective was to propose two brief screening tools (three items or less) for a use in interviews and self-administered questionnaires. Methods We tested the screening properties of combinations of items from several gambling scales, in a sample of 425 gamblers (301 non-problem gamblers and 124 disordered gamblers). Items tested included interview-based items (Pathological Gambling section of the DSM-IV, lifetime history of problem gambling, monthly expenses in gambling, and abstinence of 1 month or more) and self-report items (South Oaks Gambling Screen, Gambling Attitudes, and Beliefs Survey). The gold standard used was the diagnosis of a gambling disorder according to the DSM-5. Results Two versions of the Rapid Screener for Problem Gambling (RSPG) were developed: the RSPG-Interview (RSPG-I), being composed of two interview items (increasing bets and loss of control), and the RSPG-Self-Assessment (RSPG-SA), being composed of three self-report items (chasing, guiltiness, and perceived inability to stop). Discussion and conclusions We recommend using the RSPG-SA/I for screening problem gambling in epidemiological surveys, with the version adapted for each purpose (RSPG-I for interview-based surveys and RSPG-SA for self-administered surveys). This first triage of potential problem gamblers must be supplemented by further assessment, as it may overestimate the proportion of problem gamblers. However, a first triage has the great advantage of saving time and energy in large-scale screening for problem gambling.

    Current research is reported on precise and accurate descriptions of the earth's surface and gravitational field and on time variations of geophysical parameters. A new computer program was written in connection with the adjustment of the BC-4 worldwide geometric satellite triangulation net. The possibility that an increment to accuracy could be transferred from a super-control net to the basic geodetic (first-order triangulation) was investigated. Coordinates of the NA9 solution were computed and were transformed to the NAD datum, based on GEOS 1 observations. Normal equations from observational data of several different systems and constraint equations were added and a single solution was obtained for the combined systems. Transformation parameters with constraints were determined, and the impact of computers on surveying and mapping is discussed.

    Genetic screening is an important tool to control, minimize, and prevent genetic disorders. Saudi Arabia started the first national premarital screening (PMS) program to control inherited hemoglobin (Hb) disorders that are the most commonly inherited genetic disorders in the Kingdom of Saudi Arabia. The aim of this study was to assess the knowledge, perception, and attitude among the Saudi population about the PMS program through a questionnaire-based survey. A total of 1,047 candidates were included, divided into three groups. Group A represented the general population, group B was composed of couples presenting for PMS, and group C represented couples who had received their results. There was a fair knowledge among participants of the three groups about the nature of the tests and the targeted disorders, with more than 80% believing that it should include both sexually and genetically transmitted diseases. The concept of genetic counseling was liked by most of the participants. There was a positive attitude toward the program and the majority agreed to apply the PMS program to all couples in all country regions. More than 60% of all the participants were in favor of preventing at-risk marriages.

    A nationwide survey was performed in an attempt to investigate the distribution of average glandular doses caused by mammography for breast cancer mass screening, and to utilize the data to determine the national guidance level for mammography. A phantom equivalent to a breast with a compressed thickness of 42 mm, and glass radio-photo luminescence dosimeters were sent to 104 institutions and facilities. The dosimeters were exposed using a method based on the protocols described in the Mammography Quality Control Manual. The returned dosimeters were then analyzed, and the beam qualities and the entrance surface exposure were determined. Using these values, the average glandular doses were estimated with an accuracy of {+-}8%. The doses ranged from 0.5 to 3.7 mGy. The mean dose and the standard deviation were 1.48 mGy and 0.52 mGy, respectively. In 91 facilities, the doses were less than 2 mGy. Regarding the technical factors for facilities which presented doses of 2 mGy or over, it seemed that the doses could be easily reduced to less than 2 mGy if the settings of the auto exposure controller (AEC), anti-scatter grid and/or the film-screen system were optimized.

    Full Text Available As nations seek to address obesity and diet-related chronic disease, understanding shifts in food intake over time is an imperative. However, quantifying intake of basic foods is not straightforward because of the diversity of raw and cooked wholefoods, processed foods and mixed dishes actually consumed. In this study, data from the Australian national nutrition surveys of 1995 and 2011, each involving more than 12,000 individuals and covering more than 4500 separate foods, were coherently disaggregated into basic foods, with cooking and processing factors applied where necessary. Although Australians are generally not eating in a manner consistent with national dietary guidelines, there have been several positive changes. Australians are eating more whole fruit, a greater diversity of vegetables, more beans, peas and pulses, less refined sugar, and they have increased their preference for brown and wholegrain cereals. Adult Australians have also increased their intake of nuts and seeds. Fruit juice consumption markedly declined, especially for younger Australians. Cocoa consumption increased and shifts in dairy product intake were mixed, reflecting one of several important differences between age and gender cohorts. This study sets the context for more detailed research at the level of specific foods to understand individual and household differences.

    Domestic violence (DV) has significant health impacts for victims and their families. Despite evidence that routine screening increases the identification of DV and opportunities for support; routine screening is uncommon in Australian emergency departments (EDs). This study explored ED clinicians' level of support for DV screening; current screening practices; and perceived barriers and readiness to screen prior to a pilot intervention. Census survey of 76 ED clinicians. A number of questionnaire items were generated through a review of the literature, with readiness to screen for DV assessed through the short version of the Domestic Violence Healthcare Provider Scale [1]. The confidential and anonymous online survey was hosted on the Qualtrics platform. Descriptive and comparative statistical analysis was performed using IBM SPSS version 22. Most clinicians supported screening for DV in the ED. In the absence of protocols, 72.3% (n=55) of clinicians reported currently engaging in case-based screening, which preferenced women with physical injury. The majority did not always feel comfortable screening for DV (79.7% n=59) and reported they had received insufficient training for this role (88.7% n=55). Lower perceived self-efficacy and fear of offending were statistically associated with discomfort or negative beliefs about DV enquiry (p=<0.05). Emergency department clinicians reported feeling ill-equipped and under-prepared to inquire about and respond to DV. These findings provide valuable insight about the training and support needs of ED clinicians prior to the commencement of routine screening in EDs. Copyright © 2017. Published by Elsevier Ltd.

    High demand for housing and limited land in town area has increasing the provision of high-rise residential scheme. This type of housing has different owners but share the same land lot and common facilities. Thus, maintenance works of the buildings and common facilities must be well organized. The purpose of this paper is to identify and classify basic facilities for high-rise residential building hoping to improve the management of the scheme. The method adopted is a survey on 100 high-rise residential schemes that ranged from affordable housing to high cost housing by using a snowball sampling. The scope of this research is within Kajang area, which is rapidly developed with high-rise housing. The objective of the survey is to list out all facilities in every sample of the schemes. The result confirmed that pre-determined 11 classifications hold true and can provide the realistic classification for high-rise residential scheme. This paper proposed for redefinition of facilities provided to create a better management system and give a clear definition on the type of high-rise residential based on its facilities.

    A broad targeted screening method based on broadband collision-induced dissociation (bbCID) ultra-performance liquid chromatography high-resolution time-of-flight mass spectrometry (UPLC-HR-TOF-MS) was developed and evaluated for toxicological screening of whole blood samples. The acidic, neutral and basic substances covered by the method were identified in postmortem and antemortem whole blood samples from forensic autopsy cases, clinical forensic cases and driving under the influence of drugs (DUID) cases by a reverse target database search. The screening method covered 467 substances. Validation was performed on spiked whole blood samples and authentic postmortem and antemortem whole blood samples. For most of the basic drugs, the established cut-off limits were very low, ranging from 0.25ng/g to 50ng/g. The established cut-off limits for most neutral and acidic drugs, were in the range from 50ng/g to 500ng/g. Sample preparation was performed using simple protein precipitation of 300μL of whole blood with acetonitrile and methanol. Ten microliters of the reconstituted extract were injected and separated within a 13.5min UPLC gradient reverse-phase run. Positive electrospray ionization (ESI) was used to generate the ions in the m/z range of 50-1000. Fragment ions were generated by bbCID. Identification was based on retention time, accurate mass, fragment ion(s) and isotopic pattern. A very sensitive broad toxicological screening method using positive electrospray ionization UPLC-HR-TOF-MS was achieved in one injection. This method covered basic substances, substances traditionally analyzed in negative ESI (e.g., salicylic acid), small highly polar substances such as beta- and gamma-hydroxybutyric acid (BHB and GHB, respectively) and highly non-polar substances such as amiodarone. The new method was shown to combine high sensitivity with a very broad scope that has not previously been reported in toxicological whole blood screening when using only one injection.

    In 2013, the USPSTF issued a Grade B recommendation that long-term current and former smokers receive lung cancer screening. Shared decision-making is important for individuals considering screening, and patient-provider discussions an essential component of the process. We examined prevalence and predictors of lung cancer screening discussions pre- and post-USPSTF guidelines. Data were obtained from two cycles of the Health Information National Trends Survey (2012; 2014). The analyzed sample comprised screening-eligible current and former smokers with no personal history of lung cancer (n=746 in 2012; n=795 in 2014). Descriptive and multiple logistic regression analyses were conducted; patient-reported discussion about lung cancer screening with provider was the outcome of interest. Contrary to expectations, patient-provider discussions about lung cancer screening were more prevalent pre-guideline, but overall patient-provider discussions were low in both years (17% in 2012; 10% in 2014). Current smokers were more likely to have had a discussion than former smokers. Significant predictors of patient-provider discussions included family history of cancer and having healthcare coverage. The prevalence of patient-provider discussions about lung cancer screening is suboptimal. There is a critical need for patient and provider education about shared decision-making and its importance in cancer screening decisions. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available As a primary point of contact within the health care system, family physicians are able to play a vital role in identifying individuals with substance use disorders and connecting them to the appropriate treatment. However, there is very little data available on whether family physicians are actively screening for and treating substance use disorders. The objective of the current survey was to assess whether family physicians in Ontario are screening for alcohol, opioid and tobacco use disorders, using validated tools and providing treatment.An online survey consisting of a series of 38 primarily close-ended questions was circulated to family physicians in Ontario. Rates of screening for alcohol, opioid and tobacco dependence, use of validated tools for screening, providing treatment for dependent individuals and the current barriers to the prescription of pharmacotherapies for these drug dependences were assessed.The use of validated screening tools was limited for all three substances. Screening by family physicians for the substance use disorders among adolescents was much lower than screening among adults. Pharmacotherapy was more commonly used as an intervention for tobacco dependence than for alcohol and opioid dependence. This was explained by the lack of knowledge among family physicians on the pharmacotherapies for alcohol and opioid dependence.Findings from the current study suggest there is a need for family physicians to integrate screening for substance use disorders using validated tools into their standard medical practice. Furthermore, there is a need for increased knowledge on pharmacotherapies for alcohol and opioid use disorders. It is important to note that the low response rate is a major limitation to this study. One possible reason for this low response rate may be a lack of interest and awareness among family physicians on the importance of screening and treatment of substance use disorders in Ontario.

    To describe and compare breast and cervical cancer screening among women in Barcelona in 1992, 2001, and 2006 by social class, age, and screening approach. This was a study of trends based on analysis of Barcelona health interview surveys for the years 1992 (n=5,003), 2001 (n=10,030), and 2006 (n=6,050). Dependent variables were having regular mammographies (at least every 2 years) and having regular cytologic testing (at least every 3 years). Independent variables were age, social class, and survey year. A descriptive analysis was carried out. To compare prevalence in terms of social class and the years studied, we calculated prevalence differences (PD) and prevalence ratios (PR) by fitting robust Poisson regression models. In 1992, women aged 40?49 had more regular mammographies than those aged 50?69, with social class inequalities in both age groups. Having cervical cancer screening was more common than having breast cancer screening, with prevalence varying from 46.4% in the low social classes to 59.2% in the high classes. In 2001, breast cancer screening had risen, particularly in women aged 50?69, a tendency that had stabilized by 2006. Inequalities diminished over the period, more markedly in women aged 50?69; PRs of 1.22 and 1.58, respectively, for high and middle social classes with respect to the lowest class in 1992 fell to PRs of 1.07 and 1.08, respectively, in 2006. In the case of cervical cancer screening, inequalities also diminished but not to the same extent. Preventive screening for breast and cervical cancer has increased, and the population screening program for breast cancer among women aged 50?69 years appears to contribute more than opportunistic screening for cervical cancer in reducing social class inequalities.

    The objective of this study was to survey registered dietitians (RDs) at acute care hospitals across Canada to determine whether valid screening and assessment methods (i.e. those with formal evaluation of the psychometric and/or clinimetric properties of the tool) are used to identify protein-energy malnutrition following stroke. One hundred and twenty-five Canadian healthcare institutions admitting high volumes (≥100/year) of acute stroke patients were identified. RDs at these sites who provided services to patients recovering from acute stroke were contacted and invited to participate in an online survey. Ninety-five RDs completed the survey. Sixty dietitians (63%) indicated that patients were screened routinely at their institution, which was conducted primarily by dietitians (n = 64, 67.3%). Ten respondents (10.5%) stated they used a screening tool with previously-established validity, while 32 (33.7%) indicated they used a validated assessment tool. Among dietitians using validated tools, 40% and 64% indicated that they used modified versions of the original screening and assessment tools. The most frequently cited tools used for both screening and assessment purposes were Subjective Global Assessment and Mini Nutritional Assessment. The results of this national survey suggest that screening and assessment of nutritional status following acute stroke is conducted using tools that have not been validated previously. Implications for Rehabilitation Although the use of valid screening and assessment tools is considered part of evidence-based practice, and recommendations for their adoption are included in several national stroke-specific clinical practice guidelines, the results from an online survey suggest that they are not used in clinical practice by RDs in Canada caring for patients following stroke. There are associated risks with the use of screening and assessment tools, which have not been formally validated. The true nutritional status of

    Full Text Available Abstract Background Many studies reported that brief interventions are effective in reducing excessive drinking. This study aimed to assess the efficacy of a protocol of brief intervention for college students (BASICS, delivered face-to-face, to reduce risky alcohol consumption and negative consequences. Methods A systematic review with meta-analysis was performed by searching for randomized controlled trials (RCTs in Medline, PsycInfo, Web of Science and Cochrane Library databases. A quality assessment of RCTs was made by using a validated scale. Combined mean effect sizes, using meta-analysis random-effects models, were calculated. Results 18 studies were included in the review. The sample sizes ranged from 54 to 1275 (median = 212. All studies presented a good evaluation of methodological quality and four were found to have excellent quality. After approximately 12 months of follow-up, students receiving BASICS showed a significant reduction in alcohol consumption (difference between means = −1.50 drinks per week, 95% CI: -3.24 to −0.29 and alcohol-related problems (difference between means = −0.87, 95% CI: -1.58 to −0.20 compared to controls. Conclusions Overall, BASICS lowered both alcohol consumption and negative consequences in college students. Gender and peer factors seem to play an important role as moderators of behavior change in college drinking. Characteristics of BASICS procedure have been evaluated as more favorable and acceptable by students in comparison with others interventions or control conditions. Considerations for future researches were discussed.

    Full Text Available Abstract Background The appropriateness and cost-effectiveness of screening mammography (SM for women younger than 50 and older than 74 years is debated in the clinical research community, among health care providers, and by the American public. This study explored primary care physicians' (PCPs perceptions of the influence of clinical practice guidelines for SM; the recommendations for SM in response to hypothetical case scenarios; and the factors associated with perceived SM effectiveness and recommendations in the US from June to December 2009 before the United States Preventive Services Task Force (USPSTF recently revised guidelines. Methods A nationally representative sample of 11,922 PCPs was surveyed using a web-based questionnaire. The response rate was 5.7% (684; (41% 271 family physicians (FP, (36% 232 general internal medicine physicians (IM, (23% 150 obstetrician-gynaecologists (OBG, and (0.2% 31 others. Cross-sectional analysis examined PCPs perceived effectiveness of SM, and recommendation for SM in response to hypothetical case scenarios. PCPs responses were measured using 4-5 point adjectival scales. Differences in perceived effectiveness and recommendations for SM were examined after adjusting for PCPs specialty, race/ethnicity, and the US region. Results Compared to IM and FP, OBG considered SM more effective in reducing breast cancer mortality among women aged 40-49 years (p = 0.003. Physicians consistently recommended mammography to women aged 50-69 years with no differences by specialty (p = 0.11. However, 94% of OBG "always recommended" SM to younger and 86% of older women compared to 81% and 67% for IM and 84% and 59% for FP respectively (p = p = Conclusions A majority of physicians, especially OBG, favour aggressive breast cancer screening for women from 40 through 79 years of age, including women with short life expectancy. Policy interventions should focus on educating providers to provide tailored recommendations for

    Screening tests were carried out for radioactive cesium in foods using a NaI (Tl) scintillation survey meter. The screening level was set at 250 Bq/kg, and specimens exceeding this level were scheduled to be sent to an external testing organization, which would conduct further tests using a germanium semiconductor detector. Some specimens that did not reach the screening level were also sent to the same organization. Foodstuffs used in commercial food products circulated in Chiba city were targeted, along with food services provided to schools and day care centers. In all, 495 specimens were tested; however, no specimens exceeded the screening level. The results of verification tests confirmed that no specimen exceeded the tentative regulatory limit.

    Full Text Available The purpose of the study is to examine the associations of youth physical activity and screen time with weight status and cardiorespiratory fitness in children and adolescents, separately, utilizing a nationally representative sample. A total of 1,113 participants (692 children aged 6-11 yrs; 422 adolescents aged 12-15 yrs from the 2012 NHANES National Youth Fitness Survey. Participants completed physical activity and screen time questionnaires, and their body mass index and cardiorespiratory fitness (adolescents only were assessed. Adolescents completed additional physical activity questions to estimate daily MET minutes. Children not meeting the screen time guideline had 1.69 times the odds of being overweight/obese compared to those meeting the screen time guideline, after adjusting for physical activity and other control variables. Among adolescent, screen time was significantly associated with being overweight/obese (odds ratio = 1.82, 95% confidence interval: 1.06-3.15, but the association attenuated toward the borderline of being significant after controlling for physical activity. Being physically active was positively associated with cardiorespiratory fitness, independent of screen time among adolescents. In joint association analysis, children who did not meet physical activity nor screen time guidelines had 2.52 times higher odds of being overweight/obese than children who met both guidelines. Adolescents who did not meet the screen time guideline had significantly higher odds ratio of being overweight/obese regardless of meeting the physical activity guideline. Meeting the physical activity guideline was also associated with cardiorespiratory fitness regardless of meeting the screen time guideline in adolescents. Screen time is a stronger factor than physical activity in predicting weight status in both children and adolescents, and only physical activity is strongly associated with cardiorespiratory fitness in adolescents.

    The aim of the present study was to model indoor TV/screen viewing and a series of adult health conditions and cognitive performance in a country-wide, population-based setting in recent years. Data was retrieved from Health Survey for England, 2012. Information on demographics, lifestyle factors, self-reported health conditions, and TV and/or screen watching hours in adults was collected by household interviews. Chi-square test and survey-weighted logistic and multi-nominal modeling were performed. Of 8114 English adults aged 18-98, 4138 people (51.1 %) watched TV and/or screen daily for 2 h or more on average. Two thousand five-hundred people (30.9 %) watched for 3 h or more. TV and/or screening watching for 2+ hours was associated with endocrine or metabolic disorders, diabetes, mental disorders (including poor scores in General Health Questionnaire and Warwick-Edinburgh Mental Well-being Scale), nervous system disorders, eye complaints, circulatory system disorders, respiratory system disorders, musculoskeletal system disorders, and self-rated health. TV and/or screen watching for 3+ hours was associated with digestive disorders and clotting disorder. TV and/or screen watching for 5+ hours was associated with cancer. TV and/or screen watching for 6+, 8+, or 11+ hours was associated with bladder disease, genito-urinary system disorders or bowel disease, respectively. There were no risk associations (within 20 h) found with ear complaints, infectious disease, and blood system disorders. Future educational and public health programs minimizing TV and/or screen viewing in order to protect from physical inactivity and X-radiation might be needed while research on the combined effect of physical inactivity and X-radiation should be explored.

    In the search for new therapeutic modalities for cancer, gene therapy has attracted enormous interest over the last few years. Recently, the use of bacteria as a tumor specific protein transfer system has attracted interest. Attenuated Salmonella has been shown to provide selective colonization in tumors. This strategy to apply gene therapy for cancer has been defined as 'Radiogenic Therapy'. In this research, firstly, we screened a radiation inducible promoter of Salmonella responding to clinically relevant low dose of 10 Gy using microarray analysis. Of all genes showing a expression ratio of at least 2-fold changes relative to wild type, 168 genes were induced. To confirm the findings of the microarray by an alternative method, we investigated the transcriptional changes of radio-inducible genes using real time PCR analysis. To verify the ability of screened genes (fadB, narK, cyoA, STM1011, STM2617, and STM2632) to produce a downstream protein by irradiation, the reporter plasmids were constructed. Finally, we found that the promoter of fadB, cyoA, and STM2617 can be activated by irradiation within cancer cells. These results suggest that these genes may be the most probable candidate used in radiogenic therapy.

    We present a uniform mid-infrared imaging and photometric survey of 36 young, nearby, star-forming clusters and groups using {\\it Spitzer} IRAC and MIPS. We have confidently identified and classified 2548 young stellar objects using recently established mid-infrared color-based methods. We have devised and applied a new algorithm for the isolation of local surface density enhancements from point source distributions, enabling us to extract the overdense cores of the observed star forming regions for further analysis. We have compiled several basic structural measurements of these cluster cores from the data, such as mean surface densities of sources, cluster core radii, and aspect ratios, in order to characterize the ranges for these quantities. We find that a typical cluster core is 0.39 pc in radius, has 26 members with infrared excess in a ratio of Class II to Class I sources of 3.7, is embedded in a $A_K$=0.8 mag cloud clump, and has a surface density of 60 pc$^{-2}$. We examine the nearest neighbor dista...

    To determine how endocrinologists in Latin America deal with clinical case scenarios related to hypothyroidism and pregnancy. In January 2013, we sent an electronic questionnaire on current practice relating to management of hypothyroidism in pregnancy to 856 members of the Latin American Thyroid Society (LATS) who manage pregnant patients with thyroid disease. Subsequently, we have analyzed responses from physician members. Two hundred and ninety-three responders represent clinicians from 13 countries. All were directly involved in the management of maternal hypothyroidism and 90.7% were endocrinologists. The recommendation of a starting dose of L-thyoxine for a woman diagnosed with overt hypothyroidism in pregnancy, preconception management of euthyroid women with known thyroid autoimmunity and approach related to ovarian hyperstimulation in women with thyroid peroxidase antibodies were widely variable. For women with known hypothyroidism, 34.6% of responders would increase L-thyroxine dose by 30-50% as soon as pregnancy is confirmed. With regard to screening, 42.7% of responders perform universal evaluation and 70% recommend TSH hypothyroid pregnant women. Deficiencies in diagnosis and management of hypothyroidism during pregnancy were observed in our survey, highlighting the need for improvement of specialist education and quality of care offered to patients with thyroid disease during pregnancy in Latin America.

    This study examined the following: (1) relationships between religiosity-as measured by religious service attendance-and screening for breast, cervical, and colorectal cancers; (2) the potential mediating role of social support; and (3) the potential moderating effect of race/ethnicity. Statistical analyses showed that religiosity was associated with greater utilization of breast, cervical, and colorectal cancer screening. Social support fully mediated the relationship between religiosity and Pap screening, and partially mediated the relationship between religiosity and colorectal screening, but had no effect on the relationship between religiosity and mammography screening. Race/ethnicity moderated the relationship between religiosity and social support in the cervical cancer screening model, such that the positive association between religiosity and social support was stronger for non-Hispanic Blacks than it was for non-Hispanic Whites. These findings have implications for the role of social networks in health promotion and can inform cancer screening interventions in faith-based settings.

    This study investigated factors associated with breast and cervical cancer screening using data from a nationwide community survey. A nationwide cross-sectional study was performed in all 253 administrative districts of Korea. The breast and cervical cancer screening rate was negatively associated with the obesity (β = -2.91, 95% confidence interval [CI] = -4.73 to -1.03; β = -1.93, 95% CI = -3.43 to -0.43), positively associated with the European Quality of Life-5 Dimensions scale (β =2.53, 95% CI = 0.24 to 4.81; β = 2.51, 95% CI = 0.68 to 4.34). Moreover, higher alcohol consumption rate was negatively related to screening rates for breast cancer, while areas with higher proportion of diabetes were found to have higher screening rates. Area with higher rate of osteoarthritis had a lower screening rate for cervical cancer. This study showed breast and cervical cancer screening was associated with particular area characteristics. This ecological approach is thought to be a major complement to measures of health attributes.

    To investigate the factors associated with compliance with recommendations regarding liver cancer screening intervals and methods among individuals at high-risk for liver cancer in the Republic of Korea. We used data from the fourth Korean National Health and Nutrition Examination Survey (KNHANES IV), a representative cross-sectional nationwide survey conducted between 2007 and 2009. The liver cancer screening rate and factors associated with compliance with recommended screening intervals (6 months) and methods (both abdominal ultrasonography and serum alpha-fetoprotein testing) among individuals at high risk for liver cancer such as hepatitis B virus (HBV) carriers were investigated. Out of 24,871 KNHANES IV participants, 604 HBV carriers aged ≥ 20 years were included in our analysis. 39.6% of our study sample reported attending liver cancer screening at least once in their lifetime, 12.3% had attended within the previous 6 months, and 14.6% were screened using both recommended methods. Older age was associated with increased compliance with screening intervals (P-trend 0.011) and methods (40-49 year: OR = 3.25, 95% CI: 1.62-6.51; 50-59 years: OR = 3.09, 95% CI: 1.44-6.66; 60-69 years: OR = 3.17, 95% CI: 1.28-7.82). Unawareness of HBV infection status was negatively related to compliance with screening intervals and methods (OR = 0.30, 95% CI: 0.17-0.53; OR = 0.45, 95% CI: 0.26-0.79). Female sex (OR = 0.45, 95% CI: 0.25-0.78), lower household income (P-trend 0.011), and routine and manual occupations (OR = 0.46, 95% CI: 0.22-0.97) were associated with decreased compliance with screening methods. The liver cancer screening rate among high-risk individuals is much less suboptimal. Considering that those unaware of their HBV infection status got regular and complete liver cancer screening much less often, efforts should be made not only to decrease sociodemographic disparities, but also to better identify the high-risk population.

    Introduction Women with a history of gestational diabetes mellitus (GDM) are at increased risk for developing type 2 diabetes mellitus. We examined individual, socioeconomic, and health care use characteristics of women with a history of GDM and the association of those characteristics with diabetes screening, and we estimated their rates of undiagnosed prediabetes and diabetes. Methods Using 3 cycles of the National Health and Nutrition Examination Survey (2007–2008, 2009–2010, and 2011–2012), we identified 284 women with a history of GDM who were eligible for diabetes screening. Screening status was defined by self-report of having had a blood test for diabetes within the prior 3 years. Undiagnosed prediabetes and diabetes were assessed by hemoglobin A1c measurement. Results Among women with a history of GDM, 67% reported diabetes screening within the prior 3 years. Weighted bivariate analyses showed screened women differed from unscreened women in measured body mass index (BMI) category (P = .01) and number of health visits in the prior year (P = .001). In multivariable analysis, screening was associated with a greater number of health visits in the prior year (1 visit vs 0 visits, adjusted odds ratio [AOR], 1.91; 95% confidence interval [CI], 0.71–5.18; 2 or 3 visits, AOR, 7.05; and ≥4 visits, AOR, 5.83). Overall, 24.4% (95% CI, 18.3%–31.7%) of women had undiagnosed prediabetes and 6.5% (95% CI, 3.7%–11.3%) had undiagnosed diabetes. Conclusion More health visits in the prior year was associated with receiving diabetes screening. Fewer opportunities for screening may delay early detection, clinical management, and prevention of diabetes. Prediabetes in women with a history of GDM may be underrecognized and inadequately treated. PMID:27609302

    Recent amendments to the Child Abuse Prevention and Treatment Act tie the receipt of federal block grants to mandatory reporting of substance-exposed newborns. To determine rates of screening, testing, and reporting of drug and alcohol use at the time of delivery, we administered a telephone survey of nursing managers and perinatal social workers at Maryland birthing hospitals. Of the 34 hospitals, 31 responded (response rate 91%). Although 97% of hospitals reported universal screening, only 6% used a validated instrument. Testing was reported by 94% with 45% reporting universal maternal testing and 7% universal newborn testing. Only 32% reported obtaining maternal consent prior to testing. There is significant heterogeneity in screening and testing for substance use in birthing hospitals. Given federal reporting mandates, state-level practices need to be standardized.

    This study examined the concurrent associations of physical activity and screen-based sedentary behavior with sleep duration among adolescents by using data from the national Youth Risk Behavior Survey 2011–2013. Using latent class analysis, we identified 4 latent subgroups of adolescents with various levels of physical activity and screen-based sedentary behavior. The subgroup with high levels of physical activity and low levels of sedentary behavior generally showed greater odds of having sufficient sleep (≥8 hours/night) than the other subgroups. Findings imply that concurrent achievement of a high level of physical activity and low level of screen-based sedentary behavior is necessary to promote sufficient sleep among adolescents.

    Full Text Available Abstract Background The cytological screening programme of Viterbo has completed the second round of invitations to the entire target population (age 25–64. From a public health perspective, it is important to know the Pap-test coverage rate and the use of opportunistic screening. The most commonly used study design is the survey, but the validity of self-reports and the assumptions made about non respondents are often questioned. Methods From the target population, 940 women were sampled, and responded to a telephone interview about Pap-test utilisation. The answers were compared with the screening program registry; comparing the dates of Pap-tests reported by both sources. Sensitivity analyses were performed for coverage over a 36-month period, according to various assumptions regarding non respondents. Results The response rate was 68%. The coverage over 36 months was 86.4% if we assume that non respondents had the same coverage as respondents, 66% if we assume they were not covered at all, and 74.6% if we adjust for screening compliance in the non respondents. The sensitivity and specificity of the question, "have you ever had a Pap test with the screening programme" were 84.5% and 82.2% respectively. The test dates reported in the interview tended to be more recent than those reported in the registry, but 68% were within 12 months of each other. Conclusion Surveys are useful tools to understand the effectiveness of a screening programme and women's self-report was sufficiently reliable in our setting, but the coverage estimates were strongly influenced by the assumptions we made regarding non respondents.

    Little is known about the role of the medical home in promoting essential preventive health care services in the general pediatric population. This study examined associations between having a medical home and receipt of health screenings and anticipatory guidance. We conducted a cross-sectional analysis of the 2004-2006 Medical Expenditure Panel Survey (MEPS). Our sample included 21 055 children aged 0 to 17 years who visited a health care provider in the year prior to the survey. A binary indicator of the medical home was developed from 22 questions in MEPS, reflecting 4 of the 7 American Academy of Pediatrics' recommended components of the medical home: accessible, family-centered, comprehensive, and compassionate care. Multivariable logistic regression was used to examine the association between the medical home and receipt of specific health screenings and anticipatory guidance, controlling for confounding variables. Approximately 49% of our study sample has a medical home. The medical home, defined when the usual source of care is a person or facility, is significantly associated with 3 health screenings (ie, weight, height, and blood pressure) and several anticipatory guidance topics (ie, advice about dental checkups, diet, exercise, car and bike safety), with odds ratios ranging from 1.26 to 1.54. The medical home is associated with increased odds of children receiving some health screenings and anticipatory guidance. The medical home may provide an opportunity to improve the delivery of these services for children. Copyright 2010 Academic Pediatric Association. Published by Elsevier Inc. All rights reserved.

    Full Text Available Newborn screening (NBS follow-up protocols vary significantly by state, and there is a need to better understand the infrastructure and communication flow of NBS programs. In addition, assessment of the educational needs of families and providers with regard to the implications of NBS results is required to inform the development of appropriate informational resources and training opportunities. To begin to address these issues, we administered a web-based survey to state NBS coordinators within the Southeast Regional Newborn Screening & Genetics Collaborative (SERC. Fourteen coordinators responded to the survey, including at least one from each of the 10 SERC states/territories. Over one-third of respondents had never received formal training regarding the metabolic conditions identified on NBS. Most communicated results via telephone or fax, though two centers indicated use of a web-based platform. Only two programs were involved in directly reporting results to the family. Four programs reported a long-term follow-up protocol. Deficits were noted for primary care provider (PCP knowledge of metabolic disorders identified on NBS, and how to inform parents of abnormal results. Close to half indicated that the adequacy of the number of genetic counselors, dietitians, and medical/biochemical geneticists was minimal to insufficient. Respondents uniformly recognized the importance of providing additional educational and informational resources in multiple categories to NBS staff, PCPs, and families.

    Full Text Available Under-screening may increase the risk of cervical cancer in middle-aged women. This study aimed to investigate cervical cancer screening behaviour and its predictors among women aged 50 years or above. A population-based sample of 959 women was recruited by telephone from domestic households in Hong Kong, using random methods, and a structured questionnaire developed to survey participants. Multivariable logistic regressions were performed to examine the factors independently associated with cervical screening behaviour. Nearly half the sample (48% had never had a cervical smear test. Multivariable analyses showed that age, educational level, marital status, family history of cancer, smoking status, use of complementary therapy, recommendation from health professionals, and believing that regular visits to a doctor or a Chinese herbalist were good for their health were predictors of cervical screening behaviour. Misconceptions concerned with menopause may reduce women’s perceived susceptibility to cervical cancer, especially if they are 50 or above, and exert a negative effect on their screening behaviour. Healthcare professionals should actively approach these high-risk groups–older unmarried women, smokers, those less educated and who are generally not much concerned with their health.

    Issue addressed: To compare the level of cervical screening uptake between refugee and non-refugee African immigrant women living in Brisbane, Australia, and examine factors associated with Pap smear testing. Methods: Cross-sectional survey with a convenience sample of 254 women aged 21-62 years from 22 African countries (144 refugees, 110 non-refugees). Chi-square tests were used to compare the demographic and health-related characteristics between refugee and non-refugee women. Bivariate and multiple logistic regression analyses were used to assess the relationship between the outcome variable (Pap smear testing) and the independent variables. Results: Two-thirds of women had used Pap smear services in Australia. Chi-square test analysis established that non-refugee women were significantly more likely to have used Pap smear services than refugee women (73.6% vs 61.8% respectively; P=0.047). Immigration status, however, was not a significant predictor of cervical screening uptake in the multiple regression analyses. The significant predictors for screening uptake in these analyses were work arrangement, parity, healthcare visit, knowledge about Pap smear and perceived susceptibility to cervical cancer. Conclusion: Most women relied on opportunistic screening after receiving invitation letters to screen or after visiting health professionals for antenatal or postnatal care. So what?: The findings suggest that organised cervical screening programs are not reaching most African immigrant women living in Brisbane. It is incumbent on the public health sector, including healthcare professionals and settlement agencies working with African communities, to develop health promotion strategies that meaningfully engage African immigrant women, including those from refugee backgrounds, to enhance their knowledge about cervical cancer and screening practices.

    To identify which feasible obesity and insulin resistance (IR) screening tools are most strongly associated in adolescents by using a nationally representative sample. Adolescents aged 12.0 to 18.9 years who were participating in the National Health and Nutrition Examination Survey (NHANES) (n=3584) and who were measured for height, weight, waist circumference (WC), triceps and subscapular skinfold thickness, glycated hemoglobin, fasting glucose (FG) and fasting insulin (FI) level were included. Adolescents were split by gender and grouped by body mass index (BMI) percentile. Age- and gender-specific classifications were constructed for each obesity screening tool measure to account for growth and maturation. General linear models were used to establish groups objectively for analysis based on when IR began to increase. Additional general linear models were used to identify when IR significantly increased for each IR measure as obesity group increased and to identify the variance accounted for among each obesity-IR screening tool relationship. As the obesity group increased, homeostasis model assessment-insulin resistance (HOMA-IR) and FI significantly increased, while FG increased only (above the referent) in groups with BMI percentiles ≥95.0, and glycated hemoglobin level did not vary across obesity groups. The most strongly associated screening tools were WC and FI in boys (R(2)=0.253) and girls (R(2)=0.257). FI had the strongest association with all of the obesity measures. BMI associations were slightly weaker than WC in each in relation to IR. Our findings show that WC and FI are the most strongly associated obesity and IR screening tool measures in adolescents. These feasible screening tools should be utilized in screening practices for at-risk adolescents. Copyright © 2015 Canadian Diabetes Association. Published by Elsevier Inc. All rights reserved.

    This study examined the association between survey responses to health behaviors, personality/psychosocial factors, and self-reported sexually transmitted infections (STIs) to create a brief survey to identify youth at risk for contracting STIs. Participants included 200 racially diverse 14- to 18-year-old patients from a pediatric primary care clinic. Two sexual behavior variables and one peer norm variable were used to differentiate subgroups of individuals at risk of contracting a STI based on reported history of STIs using probability (decision tree) analyses. These items, as well as sexual orientation and having ever had oral sex, were used to create a brief sexual health screening (BSHS) survey. Each point increase in total BSHS score was associated with exponential growth in the percentage of sexually active adolescents reporting STIs. Findings suggest that the BSHS could serve as a useful tool for clinicians to quickly and accurately detect sexual risk among adolescent patients.

    A basic extraction procedure for analysis of ochratoxin A (OTA) in currants and raisins is described, as well as the occurrence of OTA and a control of heterogeneity of the toxin in samples bought for two small marketing surveys 1999/2000 and 2001/02. Most samples in the surveys were divided into two subsamples that were individually prepared as slurries and analysed separately. The limit of quantification for the method was estimated as 0.1 microg kg(-1) and recoveries of 85, 90 and 115% were achieved in recovery experiments at 10, 5 and 0.1 microg kg(-1), respectively. Of all 118 subsamples analysed in the surveys, 96 (84%) contained ochratoxin A at levels above the quantification level and five samples (4%) contained more than the European Community legislation of 10 microg kg(-1). The OTA concentrations found in the first survey were in the range Big differences were often achieved between individual subsamples of the original sample, which indicate a wide heterogeneous distribution of the toxin. Data from the repeatability test as well as recovery experiments from the same slurries showed that preparation of slurries as described here seemed to give a homogeneous and representative sample. The extraction with the basic sodium bicarbonate-methanol mixture used in the surveys gave similar or somewhat higher OTA values on some samples tested in a comparison with a weak phosphoric acid water-methanol extraction mixture.

    The incidence of colorectal cancer has been increasing in many Asian countries including Malaysia during the past few decades. A physician recommendation has been shown to be a major factor that motivates patients to undergo screening. The present study objectives were to describe the practice of colorectal cancer screening by primary care providers in Malaysia and to determine the barriers for not following recommendations. In this cross sectional study involving 132 primary care providers from 44 Primary Care clinics in West Malaysia, self-administered questionnaires which consisted of demographic data, qualification, background on the primary care clinic, practices on colorectal cancer screening and barriers to colorectal cancer screening were distributed. A total of 116 primary care providers responded making a response rate of 87.9%. About 21% recommended faecal occult blood test (FOBT) in more than 50% of their patients who were eligible. The most common barrier was "unavailability of the test". The two most common patient factors are "patient in a hurry" and "poor patient awareness". This study indicates that colorectal cancer preventive activities among primary care providers are still poor in Malaysia. This may be related to the low availability of the test in the primary care setting and poor awareness and understanding of the importance of colorectal cancer screening among patients. More awareness programmes are required for the public. In addition, primary care providers should be kept abreast with the latest recommendations and policy makers need to improve colorectal cancer screening services in health clinics.

    Basic nursing education has a major impact on the future professional practices of nurses. Nurses must be adequately trained to perform health promotion activities, such as smoking cessation. However, nurses play only a minor role in this field. The objective of this research was to describe the smoking cessation content in basic nursing programmes in Quebec. A simple descriptive mixed design (quantitative and qualitative) study was conducted among nursing programme administrators in Quebec, using a validated online questionnaire. On average, the time devoted to smoking cessation was reported to be less than one hour per year, essentially concerning the physiological and pathophysiological factors of tobacco consumption, while nursing professional assessment and counselling in smoking cessation were almost non-existent. The results confirm the need to increase and improve the time and content devoted to smoking cessation in the basic nursing education curriculum. It is also important to structure basic training courses so to improve knowledge, attitudes, and skills of future nurses in order to influence their role in smoking cessation in their future professional practice.

    Staphylococcus aureus nasal carriage is frequent in dialysis patients and is associated with an increased risk of staphylococcal infections in this population. Data from the literature showed that decolonization of S. aureus nasal carriers in hemodialysis and peritoneal dialysis reduce S. aureus catheter-related infections. During the last national congress of nephrology, a survey was conducted among volunteer dialysis physicians to evaluate their practice about screening and decolonization of S. aureus nasal carriage among their patients. Only 30 participants (45.5% [30/66]) declared to screen S. aureus nasal carriage in patients of hemodialysis and 59.6% (31/52) in peritoneal dialysis. Participants declared to decolonize their patients before insertion of a vascular catheter in 55.8% of cases. This small study would need to be completed by a national survey.

    The aim of this study was to compare breast and cervical cancer screening rates between female cancer survivors and a population without cancer to identify factors related to cervical and breast cancer screening in cancer survivors. We included 17,765 adults (738 cancer survivors and 17,027 individuals without cancer) in this study, all of whom who were 30 years of age or older and participated in the Fourth and Fifth Korean National Health and Nutritional Examination Surveys from 2007-2012. Multiple logistic regression analysis was performed to identify factors related to cervical and breast cancer screening uptake in female cancer survivors. The screening rate for breast cancer was 56.6%, which was higher than that in the non-cancer control group (P=0.001). The screening rate for cervical cancer was 51.4%, which was not different from that of the non-cancer control group. In terms of breast cancer screening, cancer survivors showed no significant difference in the rate of screening 5 years after their cancer diagnosis. However, cervical cancer survivors were less likely to have cervical cancer screening 10 years after their cancer diagnosis. There was no significant association between cancer screening and sociodemographic factors. Breast and cervical cancer screening rates in Korean female cancer survivors are low. Secondary primary cancer screening of female cancer survivors needs to be planned in a comprehensive manner, with the consideration of influences beyond sociodemographic factors.

    2011-01-01

    Full Text Available Introduction & Objective: The breast cancer is the most common malignancy in women and in recent years it is seen in younger ages. Because of dense breast tissue in these ages, the mammography sensitivity for breast cancer detection is reduced, so high quality ultrasonography (US as a combined screening method is effective. The aim of this study is the evaluation of the mammographic finding with the positive finding of ultrasonogarphy.Materials & Methods: In this cross-sectional study 300 cases were referred to the Mehr Medical Imaging Center for breast US and sonography of breast and axilla was performed. Mammography before or after US was also performed by another radiologist. All suspicious patients were referred for biopsy or surgery.Results: Mean age of patients was 46 y/o with the range of 32-76 y/o. Pathologic specimens approved malignancy in 21 patients and abscess in 1 patient. The most frequent symptom was palpable breast mass with mean diameter of 29 mm. Mean diameter of lymph nodes was 17.3 mm. Positive mammographic findings were seen in 85.7%and negative findings or only an asymmetric density in 14.3%.Conclusion: According to dense breast tissue especially in young women sensitivity of single screening by mammography is reduced in breast cancer detection, so combined screening with sonography and mammography especially in younger women improves the detection rate of breast carcinoma.

  18. Informed Choice in the German Mammography Screening Program by Education and Migrant Status: Survey among First-Time Invitees.

    Directory of Open Access Journals (Sweden)

    Eva-Maria Berens

    Full Text Available Breast cancer is the most prevalent cancer among women and mammography screening programs are seen as a key strategy to reduce breast cancer mortality. In Germany, women are invited to the population-based mammography screening program between ages 50 to 69. It is still discussed whether the benefits of mammography screening outweigh its harms. Therefore, the concept of informed choice comprising knowledge, attitude and intention has gained importance. The objective of this observational study was to assess the proportion of informed choices among women invited to the German mammography screening program for the first time. A representative sample of 17,349 women aged 50 years from a sub-region of North Rhine Westphalia was invited to participate in a postal survey. Turkish immigrant women were oversampled. The effects of education level and migration status on informed choice and its components were assessed. 5,847 (33.7% women responded to the postal questionnaire of which 4,113 were used for analyses. 31.5% of the women had sufficient knowledge. The proportion of sufficient knowledge was lower among immigrants and among women with low education levels. The proportion of women making informed choices was low (27.1%, with similar associations with education level and migration status. Women of low (OR 2.75; 95% CI 2.18-3.46 and medium education level (OR 1.49; 95% CI 1.27-1.75 were more likely to make an uninformed choice than women of high education level. Turkish immigrant women had the greatest odds for making an uninformed choice (OR 5.30, 95% CI 1.92-14.66 compared to non-immigrant women. Other immigrant women only had slightly greater odds for making an uninformed choice than non-immigrant women. As immigrant populations and women with low education level have been shown to have poor knowledge, they need special attention in measures to increase knowledge and thus informed choices.

  20. Strategies for Using Plagiarism Software in the Screening of Incoming Journal Manuscripts: Recommendations Based on a Recent Literature Survey.

    Lykkesfeldt, Jens

    2016-08-01

    In recent years, several online tools have appeared capable of identifying potential plagiarism in science. While such tools may help to maintain or even increase the originality and ethical quality of the scientific literature, no apparent consensus exists among editors on the degree of plagiarism or self-plagiarism necessary to reject or retract manuscripts. In this study, two entire volumes of published original papers and reviews from Basic & Clinical Pharmacology & Toxicology were retrospectively scanned for similarity in anonymized form using iThenticate software to explore measures to predictively identify true plagiarism and self-plagiarism and to potentially provide guidelines for future screening of incoming manuscripts. Several filters were applied, all of which appeared to lower the noise from irrelevant hits. The main conclusions were that plagiarism software offers a unique opportunity to screen for plagiarism easily but also that it has to be employed with caution as automated or uncritical use is far too unreliable to allow a fair basis for judging the degree of plagiarism in a manuscript. This remains the job of senior editors. Whereas a few cases of self-plagiarism that would not likely have been accepted with today's guidelines were indeed identified, no cases of fraud or serious plagiarism were found. Potential guidelines are discussed.

    The authors investigated the use of simulator platforms in fourth-year medical student education. To evaluate which simulation platform students preferred for learning dermatologic procedures and to assess the effectiveness of the exercise in terms of the change in confidence that the students had performing dermatologic procedures. After medical students were instructed on how to perform a punch biopsy and then assisted in executing the task, they were surveyed to determine their preferred simulation platform and simulator properties. Students were surveyed at the beginning and completion of the teaching block. One hundred fifty-seven students completed the skills laboratory, and 78 completed the preference questionnaire. Of the 11 surveyed categories, students preferred the pig foot in eight categories. Seventy students responded to a surgical skills questionnaire that assessed their overall confidence in planning and executing the procedure before and after the skills laboratory. The students had a statistically significant increase in confidence in dermatologic procedural skills as a result of the activity. Preference data show that the pig foot model is preferred for teaching dermatologic surgical skills. These results re-affirm that the pig foot model is an effective, low-cost solution for training. © 2014 by the American Society for Dermatologic Surgery, Inc. Published by Wiley Periodicals, Inc.

    Full Text Available Background lodine deficiency disorders (IDD are a significant public health problem globally. Iodine deficiency may cause subclinical hypothyroidism during pregnancy and early infancy. Neonatal thyroid screening of serum thyroid-stimulating hormone (TSH to detected hypothyroidism may olso be used to determine the prevcalence of IDD in a population. Previous studies reported mild IDD status in differen parts of Indonesia Objective To evaluate the iodine status of neonates born in Mitra Keluarga Surabaya Hospital (MKSH by TSH screening over a 6-year period. Methods This is a cross-sectional and hospital-based study conducted in MKSH from January 2005 to December 2010. Of the 5,619 infants took part in this study. Blood specimens for TSH measurement were collected from subjects 2 to 6 days after birth, and sent to a reference laboraratory for evaluation. Using the neonatal TSH values, the iodine deficiency level of the group was determined according to the WHO/UNICEF/International Council for the Control of IDD criteria Results A total of 3,349 newborn babies underwent neonatal TSH screening in MKSH. Subjects’ mean TSH concentration was 5.14 mIU/L. A TSH concentration > 5mIU/L was found in 1270 (37.9% subjects, 166 (27.6% in 2005, 252 (44.0% in 2006, 331 (47.1% in 2007, 356 (57.7% in 2008, 114 (20.7% in 2009 and 51 (16.8% in 2010. On the basis of the WHO/UNICEF/International Council for the Control of Iodine Deficiency Disorder criteria, this frequency corresponded to a moderate level of IDD. Twenty-two neonates had TSH > 20 mIU/L from which 2 infants were confirmed positive for hypothyroidism. Conclusion A 6-year study of 3,349 newborns screenerd for TSH revealed that 37.9% of subjects had TSH concentration of more than 5mIU/L. this frequency indicates a moderate level of IDD in the study population.

    Socioeconomic disparities influence the usage rate of advanced communication technologies in Canada. It is important to assess all patient interactions with computers and electronic devices based on these socioeconomic differences. This project studied the ease of use of a touch-screen interface program for collecting patient feedback. The interface collected feedback on physicians' communication skills, an important health concern that has been garnering more and more attention. A concurrent paper survey was used to gather information on the socioeconomic status and the usability of the touchscreen device. As expected, patients who were older, had lower annual household income, and had lower educational attainment were associated with more difficulty using the devices. Surprisingly, 94% of all users (representing a wide range of socioeconomic status backgrounds) rated the device as easy to use.

    Social and anecdotal reports suggest a predilection for visual media among individuals on the autism spectrum, yet no formal investigation has explored the extent of that use. Using a distributed questionnaire design, parents and caregivers report on time allotted toward media, including observable behaviors and communicative responses. More time was spent engaged with electronic screen media (ESM) than any other leisure activity. Television and movie viewing was more popular than computer usage. Across media platforms, animated programs were more highly preferred. Prevalent verbal and physical imitation was reported to occur during and following exposure to ESM. Clinical implications to strategically incorporate ESM into learning approaches for children with autism spectrum disorders (ASD) are provided.

    Full Text Available Purpose: To determine whether the Wu-Jones Motion Sensitivity Screening Test (MSST accurately reflects the burden of optic nerve disease in several onchoendemic communities in Africa. Materials and Methods: The MSST was used to evaluate subjects in the communities of Raja in Sudan, Bushenyi in Uganda, Morogoro in Tanzania, and Ikon, Olomboro, and Gembu in Nigeria. Motion sensitivity was expressed as a percentage of motion detected in the individual eye, and this was averaged for the community. A perfectly normal eye would detect all motion and score 100%. Results: In this study, 3858 eyes of 2072 subjects were tested. The test was completed in 76% of respondents. Acceptability was high. Average test time was 120.4 s. The overall mean motion sensitivity of all eyes tested was 88.49%, ±17.49. Using a cutoff level of 50%, 6.4% of all subjects tested were subnormal. The highest proportion of subnormals recorded was in Morogoro at 12.7%. Severe defects in a community best correlated with optic nerve disease prevalence, while the proportion of the defect from a higher cutoff level best correlated with overall ocular morbidity. A repeat examination in the next 5 years following ivermectin treatment will show the influence, if any, on community-wide MSST performance. Conclusion: A wide range in community scores reflected disease diversity. The MSST appears to be a useful test in community-wide screening and diagnosis as it reflects the general level of ocular pathology and specifically, optic nerve disease.

  8. Survey and screening of intermediate-size photovoltaic total energy and electric applications

    One of the principal objectives of this photovoltaic mission analysis effort has been to identify and evaluate applications for photovoltaic solar energy conversion that could lead to significant contributions to the national energy supply and that would provide attractive opportunities for application experiments aimed at stimulating the adoption of photovoltaic technology. The scope of the study has included applications both for electric-only photovoltaic (PV) systems and for photovoltaic total energy systems (PTES), i.e., systems that provide both photovoltaic electricity and solar thermal energy to meet all or part of the energy demand at a single load point or a group of related load points. In either case, both flat-plate and concentrating systems have been considered and it has been assumed that the thermal energy is collected in and transported by the fluid used in an active cooling system for the photovoltaic cells. Because the efficiency of photovoltaic devices decreases rapidly with increasing temperature and because the operational lifetime of such devices is reduced by prolonged operation at elevated temperatures, a practical upper limit of about 200/sup 0/C (400/sup 0/F) was assumed for the temperature at which arrays can be allowed to be operated. This limitation, in turn, places an upper bound on the temperature at which solar thermal energy is available in PTES applications. An initial screening aimed at identifying the most promising applications has therefore been required, with the expectation that detailed evaluation will be made of only the higher-ranking candidates. A description of the screening procedure that was adopted and a discussion of the results are presented.

    Breast density notification laws, passed in 19 states as of October 2014, mandate that patients be informed of their breast density. The purpose of this study is to assess the impact of this legislation on radiology practices, including performance of breast cancer risk assessment and supplemental screening studies. A 20-question anonymous web-based survey was emailed to radiologists in the Society of Breast Imaging between August 2013 and March 2014. Statistical analysis was performed using Fisher's exact test. Around 121 radiologists from 110 facilities in 34 USA states and 1 Canadian site responded. About 50% (55/110) of facilities had breast density legislation, 36% of facilities (39/109) performed breast cancer risk assessment (one facility did not respond). Risk assessment was performed as a new task in response to density legislation in 40% (6/15) of facilities in states with notification laws. However, there was no significant difference in performing risk assessment between facilities in states with a law and those without (p facilities in states with laws implemented handheld whole breast ultrasound (WBUS), automated WBUS, and tomosynthesis, respectively. The ratio of facilities offering handheld WBUS was significantly higher in states with a law than in states without (p facilities are offering supplemental screening with WBUS and tomosynthesis, and many are performing formal risk assessment for determining patient management.

    For the construction of a coal mine assessment technology system, surveys are conducted on the current state and technology trends of resources-related GIS (geographical information system) in other countries. When one ponders over coal-rich areas to be newly explored and developed in one's study on the stable exploitation of coal abroad and its import to this country, what interests one gradually shifts from known superior large-scale coal mine areas to next-generation coal mine areas yet to be exploited. Accordingly, it is mandatory to build an assessment-oriented comprehensive technology system capable of promptly dealing with any changes in natural, geological conditions that may be presented by coal mines to be exploited. Although GIS is recognized as a useful means not only in the field of natural science but also in other fields whose data may be plotted on a map, its position is not yet established when it comes to coal resources. It is therefore necessary to promptly introduce GIS into the field of coal. In fiscal 1998, on-site surveys were conducted not only in Japan but also in the U.S., Canada, and Australia who are senior to Japan in terms of GIS application. Also, information was collected from literature and via Internet, surveys were conducted about the use of GIS in the field of earth science especially in the field of coal resources, and the state of the digital data utilizing setup indispensable for the proper operation of GIS was investigated.

    The basic helix-loop-helix (bHLH) proteins play essential roles in a wide range of developmental processes in higher organisms. bHLH family members have been identified in over 20 organisms, including nematode, fruit fly, and human. Our study identified 114 rat and 14 additional mouse bHLH members in rat and mouse genomes, respectively. Phylogenetic analyses revealed that both rat and mouse had 49, 26, 15, 4, 12, and 4 bHLH members in groups A, B, C, D, E, and F, respectively. Only the rat Mxi1 gene has two copies in the genome. All other rat bHLH genes and all mouse bHLH genes are single-copy genes. The chromosomal distribution pattern of mouse, rat, and human bHLH genes suggests the emergence of some bHLH genes through gene duplication, which probably happened at least before the divergence of vertebrates from invertebrates. The present study provides useful information for future studies using rat as a model animal for mammalian development.

    Fishes have been used as laboratory animal for research of estrogenic endocrine disrupters by many researchers. However, much less attention was paid to the possibility that compounds with estrogenic activity are present in fish diets. In order to examine this possibility, we measured the estrogenic activity in commercial fish feed by in vitro yeast estrogen-screen (YES) assay based on the binding ability of tested compounds to estrogen receptors. Estrogenic activity was detected in all the commercial fish feed examined (0.2-6.2 ng estradiol equivalent/g fish feed), some phytoestrogens (genistein, formononetin, equol and coumestrol; relative activity to estradiol, 8.6 x 10(-6)-1.1 x 10(-4) by giving a value of 1.0 to estradiol) and some androgens (testosterone, 11-ketotestosterone and 5 alpha-dihydrotestosterone; relative activity to estradiol, 3.0 x 10(-6)-1.2 x 10(-4)). Therefore, it is possible that these compounds could affect the results of in vivo estrogen assay, such as vitellogenin production in male fish, especially when fish are fed commercial feed.

    Because diabetes is associated with increased colorectal cancer (CRC) risk, it is important that people with diabetes receive CRC screenings according to guidelines. In addition, many diabetes self-care recommendations are associated with a reduced risk of CRC. This study aims to identify potential opportunities for enhancing CRC prevention within the context of diabetes management. Using data from 1,730 adults with diabetes aged 50-75 years who responded to the 2010 National Health Interview Survey, we calculated population estimates of behaviors consistent with US Preventive Services Task Force guidelines for CRC screening and American Diabetes Association recommendations for diabetes care. We examined bivariate associations between CRC screening and selected diabetes self-care behaviors associated with CRC risk. Results were stratified by demographic characteristics. Thirty-nine percent of adults with diagnosed diabetes were not up-to-date with CRC screenings. Sixteen percent smoked and 2 % exceeded alcohol intake recommendations. Among those capable of exercise, 69 and 90 % did not meet aerobic exercise and resistance training recommendations, respectively. CRC screening was generally not associated with diabetes self-care behaviors. Among some demographic groups, CRC screening was associated with adequate aerobic activity, not smoking, and being overweight or obese. Many adults with diabetes do not follow guidelines for CRC screening or recommendations for diabetes care that may also reduce CRC risk. Thus, opportunities may exist to jointly promote CRC screening and prevention and diabetes self-management among adults with diabetes.

    The Korean Breast Cancer Society (KBCS) has reported a nationwide breast cancer data since 1996. We present a comprehensive report on the facts and trends of breast cancer in Korea in 2013. Data on the newly diagnosed patients in the year 2013 were collected from 99 hospitals by using nationwide questionnaire survey. Clinical characteristics such as stage of cancer, histologic types, biological markers, and surgical management were obtained from the online registry database. A total of 19,316 patients were newly diagnosed with breast cancer in 2013. The crude incidence rate of female breast cancer including carcinoma in situ was 76.2 cases per 100,000 women. The median age at diagnosis was 50 years, and the proportions of postmenopausal women with breast cancer accounted for more than half of total patients. The proportion of early breast cancer increased consistently, and the pathologic features have changed accordingly. Breast-conserving surgery was performed in more cases than total mastectomy in the year. The total number of breast reconstruction surgeries markedly increased approaching 3-fold in last 11 years. According to annual percentile change of invasive cancer incidence, the incidence increased rapidly until 2010. And thereafter the increase of it became steadier. For ductal carcinoma in situ, the incidence consistently increased during the same period without any joinpoint. Analysis of nationwide registry data will contribute to defining of the trends and characteristics of breast cancer in Korea.

    Full Text Available Abstract Background The "Put Prevention into Practice" campaign of the US Public Health Service (USPHS was launched with the dissemination of the Clinician's Handbook of Preventive Services that recommended standards of clinical care for various prevention activities, including preventive clinical strategies to reduce the risk of adverse drug events. We explored whether nonprescribing clinicians such as chiropractors may contribute to advancing drug safety initiatives by identifying potential adverse drug events in their chiropractic patients, and by bringing suspected adverse drug events to the attention of the prescribing clinicians. Methods Mail survey of US chiropractors about their detection of potential adverse drug events in their chiropractic patients. Results Over half of responding chiropractors (62% reported having identified a suspected adverse drug event occurring in one of their chiropractic patients. The severity of suspected drug-related events detected ranged from mild to severe. Conclusions Chiropractors or other nonprescribing clinicians may be in a position to detect potential adverse drug events in the community. These detection and reporting mechanisms should be standardized and policies related to clinical case management of suspected adverse drug events occurring in their patients should be developed.

    Personality refers to the individual style in characteristic patterns of thinking, feeling and behaving. Traits may configure a personality disorder when there is a long-lasting rigid pattern of inner experience that deviates from the expectations of the individual's culture, are inflexible and form maladaptative schemes in different interpersonal scenarios. Given the pervasiveness of this structure, they cause impairment of functioning in the affected person. To establish the prevalence of personality traits in all selected adults, using the module-structured interview WHO WHM-CIDI-CAPI for clusters A, B and C of personality traits. Colombian National Survey on Mental Health with persons older than 18 years of age. Personality traits that are the most frequently described: Cluster A 46% (95%CI, 45.2-48.1) of people believe they are convinced that there are conspiracies behind many things in the world. Regarding the features of cluster B, 35.6% (95%CI, 34.2-37.0) of the population reports that generally they do not feel bad when offending or upsetting someone and 35.4% (95%CI, 33.9-36.8) refer to show feelings to anyone. The highest proportion of traits were found to the probable borderline personality disorder, as 4.6% (95%CI, 4.1-5.2) of the Colombian population aged 18 and older has 6 or more features of this type, and is the widely reported as an individual entity with similar rates in men and women. The high prevalence of disruptive personality traits requires more research. The high prevalence reported for borderline personality traits suggests the need to implement measures to improve and integrate a collaborative model of care for people afflicted with a possible borderline personality disorder.

    This study sought to learn the wishes of young adolescents via an open-ended survey question and to determine the association of these wishes with sociodemographic variables. We performed a cross-sectional study of consecutive adolescents aged 11-14 years who had a well-child visit at a clinic with a diverse patient population, who completed a Guidelines for Adolescent Preventive Services (GAPS) previsit health questionnaire, and who answered the question, "If you could have three wishes come true, what would they be?" Responses to this question were double-coded according to thematic content and whether wishes were for self, others, or both. Among 96 respondents, wishes for others were listed more frequently by girls than by boys (54% versus 31%; P = .02). Girls also had more family-oriented wish themes (27% versus 10%; P = .04). Boys were more likely to wish for success (17% versus 4%; P = .05). Among respondents with private insurance, 45% wished for the good for the world, with responses such as "world peace"; only 12% of respondents with Medicaid wished for the good of the world (P = .01). No statistically significant differences were identified by race/ethnicity or age. Positive future orientation themes such as career were not as prioritized as previously suggested in the literature. The sample population derives from a single university-based clinic in North Carolina; while diverse, this population may not be representative of larger groups. Many wishes seemed predictable (ie, for wealth, athleticism), but occasionally wishes were poignant and original ("to have papers for my parents to pass the border"); this finding reinforces the value of listening to adolescents' wishes. Both sex and insurance status were related to wish themes. Further research should determine how knowledge of adolescents' wishes can be used to best direct individual care.

    Health system reforms are the most strategic issue that has been seriously considered in healthcare systems in order to reduce costs and increase efficiency and effectiveness. The costs of health system finance in our country, lack of universal coverage in health insurance, and related issues necessitate reforms in our health system financing. The aim of this research was to prepare a structure of framework for social health insurance in Iran and conducting a comparative study in selected countries with social health insurance. This comparative descriptive study was conducted in three phases. The first phase of the study examined the structure of health social insurance in four countries - Germany, South Korea, Egypt, and Australia. The second phase was to develop an initial model, which was designed to determine the shared and distinguishing points of the investigated structures, for health insurance in Iran. The third phase was to validate the final research model. The developed model by the Delphi method was given to 20 professionals in financing of the health system, health economics and management of healthcare services. Their comments were collected in two stages and its validity was confirmed. The study of the structure of health insurance in the selected countries shows that health social insurance in different countries have different structures. Based on the findings of the present study, the current situation of the health system, and the conducted surveys, the following framework is suitable for the health social insurance system in Iran. The Health Social Insurance Organization has a unique service by having five funds of governmental employees, companies and NGOs, self-insured, villagers, and others, which serves as a nongovernmental organization under the supervision of public law and by decision- and policy-making of the Health Insurance Supreme Council. Membership in this organization is based on the nationality or residence, which the insured by

    Cancer screening participation rates in Germany differ depending on patients' gender. International studies have found that patient-physician gender concordance fosters recommendation and conducting of cancer screening, and especially cancer screening for women. We aimed to ascertain whether gender concordance influences general practitioners' (GPs') rating of the usefulness of cancer screening, as well as their recommendations and readiness to conduct cancer screening in general practice in Germany. For an exploratory cross-sectional survey, 500 randomly selected GPs from all over Germany were asked to fill in a questionnaire on cancer screening in general practice between March and June 2015. We asked them to rate the usefulness of each cancer screening examination, how frequently they recommended and conducted them and whether they viewed GPs or specialists as responsible for carrying them out. We used multiple logistic regression to analyse gender effect size by calculating odds ratios. Our study sample consisted of 139 GPs of which 65% were male. Male and female GPs did not differ significantly in their rating of the general usefulness of any of the specified cancer screening examinations. Male GPs were 2.9 to 6.8 times as likely to consider GPs responsible for recommending and conducting PSA testing and digital rectal examinations and were 3.7 to 7.9 times as likely to recommend and conduct these examinations on a regular basis. Patient-physician gender concordance made it more likely that male-specific cancer screenings would be recommended and conducted, but not female-specific screenings. [Box: see text].

    Full Text Available Background: Cancer-screening programs are effective in reducing cancer prevalence and mortality; however, cancer remains the leading cause of death in elderly people in Korea. The aim of this study was to identify the factors associated with elders’ participation in the National Cancer Screening Program (NCSP and differences in screening rates by gender.Methods: Original data from the Korea National Health and Nutrition and Examination Survey were analyzed by logistic regression analysis. The sample consisted of 5,505 elderly individuals over age 60. Selected demographic variables, cancer screening participation, physical and psychological health status, and lifestyle were examined.Results: The NCSP participation rates decreased in both men and women as age increased. Private medical insurance (OR 95% CI: 1.04–1.78, one or more chronic disease (OR 95% CI: 1.07–1.71, and current smoker (OR 95% CI: 0.52–0.94 had the strongest associations with cancer screening participation among men after multivariate adjustment. In contrast, cancer screening participation among women was significantly associated only with living place (OR 95% CI: 1.06–2.203 after multivariate adjustment.Conclusions: Effective health promoting interventions for elders require individualized programs that address gender-related factors associated with elders’ participation in cancer screening programs.

    Questionnaire development, validation and completion. Develop comprehensive survey of sexuality issues including validated self-report versions of the International Spinal Cord Injury male sexual function and female sexual and reproductive function basic data sets (SR-iSCI-sexual function). People with spinal cord damage (SCD) living in the community, Australia from August 2013 to June 2014. An iterative process involving rehabilitation medicine clinicians, a nurse specialising in sexuality issues in SCD and people with SCD who developed a comprehensive survey that included the SR-iSCI-sexual function. Participants recruitment through spinal rehabilitation review clinic and community organisations that support people with SCD. Surveys completed by 154 people. Most were male (n=101, 65.6%). Respondents' median age was 50 years (interquartile range (IQR) 38-58), and they were a median of 10 years (IQR 4-20) after the onset of SCD. Sexual problems unrelated to SCD were reported by 12 (8%) respondents, and 114 (n=75.5%) reported sexual problems because of SCD. Orgasms were much less likely (χ(2)=13.1, P=0.006) to be normal in males (n=5, 5%) compared with females (n=11, 22%). Males had significantly worse (χ(2)=26.0, P=0.001) psychogenic genital functioning (normal n=9, 9%) than females (normal n=13, 26%) and worse (χ(2)=10.8, P=0.013) reflex genital functioning. Normal ejaculation was reported in only three (3%) men. Most (n=26, 52%) women reported reduced or absent menstruation pattern since SCD. The SR-iSCI-sexual function provides a useful tool for researchers and clinicians to collect information regarding patient-reported sexual functioning after SCD and to facilitate comparative studies.

    With an objective to make clear the basic information about aged and handicapped persons requiring welfare goods upon the development thereof, this survey performed a questionnaire survey to business entities performing design, development, improvement and fitting of welfare goods. The questionnaire survey selected 879 business entities involved in manufacture and sale of the welfare goods. The effective reply recovery rate was 19.3%. The questions had the data contents required by products classified into body dimensions, motion capability, sensory functions, and work capability, asking to state data contents required for each item, reasons for the needs, and data sources. The data source currently utilized reveals that most of the replied enterprises utilize data derived from the company's own measurements, developments and experiences. The contents thereof indicate that the data are too old, the data contents do not match the current situation, and no required data are available. In designing, developing and fitting the welfare goods, the required data may not necessarily be obtained, whereas improvement in the database is strongly desired. (NEDO)

    Full Text Available A strategy for analyzing formaldehyde in beer, wine, spirits, and unrecorded alcohol was developed, and 508 samples from worldwide origin were analyzed. In the first step, samples are qualitatively screened using a simple colorimetric test with the purpald reagent, which is extremely sensitive for formaldehyde (detection limit 0.1 mg/L. 210 samples (41% gave a positive purpald reaction. In the second step, formaldehyde in positive samples is confirmed by quantitative spectrophotometry of the chromotropic acid-formaldehyde derivative combined with Multivariate Curve Resolution-Alternating Least Squares (MCR-ALS. Calculation of UV-VIS and 13C NMR spectra confirmed the monocationic dibenzoxanthylium structure as the product of the reaction and disproved the widely cited para,para-quinoidal structure. Method validation for the spectrophotometric procedure showed a detection limit of 0.09 mg/L and a precision of 4.2–8.2% CV. In total, 132 samples (26% contained formaldehyde with an average of 0.27 mg/L (range 0–14.4 mg/L.

    Bilateral Breast Reduction (BBR) is a common procedure performed by Breast and Plastic surgeons in the UK. No consensus exists regarding preoperative screening for malignancy or for selective criteria for such screening. Preoperative BBR screening practices among UK Breast and Plastic surgeons are unknown. Ascertain the preoperative and postoperative BBR screening practices of UK Breast and Plastic surgeons. A questionnaire was posted to all 434 Breast and 335 Plastic surgeons in the UK. All results were analysed with relevant statistical methods. 64% of Breast surgeons and 72% of Plastic surgeons responded. 40% of Breast surgeons and 91% of Plastic surgeons perform BBR. Routine radiological screening: 92% Breast 41% Plastic (p Plastic. Routine histology for BBR specimens: 96% Breast 90% Plastic. Selective screening of patients aged 30-40 years old: Breast 38% Plastic 10%. Selective screening of patients aged 40-50: Breast 78%, Plastic 53%. Selective screening of patients with strong family history of breast cancer: Breast 72%, Plastic 91%. Selective screening of patients with previous breast cancer: Breast 77%, Plastic 93%. There are significant differences in practice between UK Breast surgeons and Plastic surgeons in preoperative oncological screening for BBR. The large discrepancy in preoperative radiological screening, reflects a ubiquitous pro-screening ideology among Breast surgeons not prevalent among Plastic surgeons. These results will provoke debate towards the direction of consensus to ultimately reflect best practice. Copyright © 2010. Published by Elsevier Ltd.

    Full Text Available Background: A prediction formula for mean pulmonary artery pressure (MPAP using standard lung function measurement has been recently validated to screen for pulmonary hypertension (PH in idiopathic pulmonary fibrosis (IPF patients. Objective: To test the usefulness of this formula as a new non invasive screening tool for PH in IPF patients. Also, to study its correlation with patients′ clinical data, pulmonary function tests, arterial blood gases (ABGs and other commonly used screening methods for PH including electrocardiogram (ECG, chest X ray (CXR, trans-thoracic echocardiography (TTE and computerized tomography pulmonary angiography (CTPA. Materials and Methods: Cross-sectional study of 37 IPF patients from tertiary hospital. The accuracy of MPAP estimation was assessed by examining the correlation between the predicted MPAP using the formula and PH diagnosed by other screening tools and patients′ clinical signs of PH. Results: There was no statistically significant difference in the prediction of PH using cut off point of 21 or 25 mm Hg (p0 = 0.24. The formula-predicted MPAP greater than 25 mm Hg strongly correlated in the expected direction with O2 saturation (r = −0.95, P < 0.000, partial arterial O2 tension (r = −0.71, P < 0.000, right ventricular systolic pressure measured by TTE (r = 0.6, P < 0.000 and hilar width on CXR (r = 0.31, P = 0.03. Chest symptoms, ECG and CTPA signs of PH poorly correlated with the same formula (P > 0.05. Conclusions: The prediction formula for MPAP using standard lung function measurements is a simple non invasive tool that can be used as TTE to screen for PH in IPF patients and select those who need right heart catheterization.

    Full Text Available Abstract Background Racial and ethnic disparities in cervical cancer screening have been attributed to socioeconomic, insurance, and cultural differences. Our objective was to explore racial and ethnic differences in adherence to cervical cancer screening recommendations among female post-graduate physicians. Methods We conducted a cross-sectional survey at one university hospital among a convenience sample of 204 female post-graduate physicians (52% of all potential participants, examining adherence to United States Preventive Services Task Force cervical cancer screening recommendations, perception of adherence to recommendations, and barriers to obtaining care. Results Overall, 83% of women were adherent to screening recommendations and 84% accurately perceived adherence or non-adherence. Women who self-identified as Asian were significantly less adherent when compared with women who self-identified as white (69% vs. 87%; Relative Risk [RR] = 0.79, 95% Confidence Interval [CI], 0.64–0.97; P Conclusion Among a small group of insured, highly-educated physicians who have access to health care, we found racial and ethnic differences in adherence to cervical cancer screening recommendations, suggesting that culture may play a role in cervical cancer screening.

    Background High tuberculosis (TB) burden countries should consider systematic screening among adults in the general population. We identified symptom screening rules to be used in addition to cough ≥2 weeks, in a context where X-ray screening is not feasible, aiming to increase the sensitivity of screening while achieving a specificity of ≥85%. Methods We used 2010 Zambia South Africa Tuberculosis and HIV/AIDS Reduction (ZAMSTAR) survey data: a South African (SA) training dataset, a SA testing dataset for internal validation and a Zambian dataset for external validation. Regression analyses investigated relationships between symptoms or combinations of symptoms and active disease. Sensitivity and specificity were calculated for candidate rules. Results Among all participants, the sensitivity of using only cough ≥2 weeks as a screening rule was less than 25% in both SA and Zambia. The addition of any three of six TB symptoms (cough <2 weeks, night sweats, weight loss, fever, chest pain, shortness of breath), or 2 or more of cough <2 weeks, night sweats, and weight loss, increased the sensitivity to ~38%, while reducing specificity from ~95% to ~85% in SA and ~97% to ~92% in Zambia. Among HIV-negative adults, findings were similar in SA, whereas in Zambia the increase in sensitivity was relatively small (15% to 22%). Conclusion High TB burden countries should investigate cost-effective strategies for systematic screening: one such strategy could be to use our rule in addition to cough ≥2 weeks. PMID:28257424

    It has been recommended that screening for sexually transmitted disease (STDs) be carried out at the time of termination of pregnancy to allow prevention of post-abortion infection. Screening offers the opportunity to treat an infected woman and prevent serious complications following the termination procedure. Our findings indicate that general practitioners (GPs) in South Thames did not routinely carry out screening and few realized it took place at referral centres. PMID:9624755

    In cancer screening programs, performing appropriate further work-up is essential. In order to elucidate whether the further work-up for the subjects with positive screening results by sputum cytology was performed appropriately, the present study was conducted as the first large-scale thorough survey in Japan. All of the lung cancer screening records from 2007 to 2012 in Ishikawa Prefecture were reviewed. Additional investigations about the further work-up were performed. In total, 2 234 984 people were invited to undergo lung cancer screening, and 494 424 people participated in the screening. Of these, 25 264 people underwent sputum cytology, and 68 positive cases were identified. Three of these 68 cases did not undergo further work-up, and another three cases had already been diagnosed to have lung cancer. Forty-five of the remaining 62 cases did not have suspicious chest shadows, and bronchoscopic examinations were performed in 36 cases. Seventeen of these 36 cases were diagnosed as having cancer, whereas none of the nine cases who did not receive the examination was diagnosed (P = 0.038). A bronchoscopic examination was not performed due to other medical conditions in three cases, due to the patient's refusal in another three cases and in the remaining three cases, the reasons were unknown. The participation rate for further work-up was very high. However, there are some issues to be resolved regarding the transmission of information. With our new registered hospital system, the quality assurance of our screening program will be improved. © The Author 2014. Published by Oxford University Press. All rights reserved.

    A new method was established for the simultaneous determination of 15 basic artificial dyes in fishery products by ultra performance liquid chromatography coupled with quadrupole-time of flight mass spectrometry (UPLC-Q-TOF MS). The analytes in fishery products were extracted with acetonitrile containing 10% (v/v) acetic acid, then purified by dispersive solid phase extraction with C18-silicone adsorbent. The compounds were separated by a C18 column with acetonitrile and 0.1% (v/v) formic acid-5 mmol/L ammonium acetate solution as the mobile phases, and measured by UPLC-Q-TOF MS with electrospray ionization in positive mode. As a result, the limits of quantification (LOQs, S/N = 10) of the 15 target compounds were 0.1-100 μg/kg in fishery products. The 15 analytes behaved linearly in their respective ranges with the correlation coefficients no less than 0.993. The average recoveries of the 15 analytes spiked at three levels were ranged from 80.60% to 107.37% with the RSDs of 3.33%-6. 69% (n = 6). This method is suitable for routine qualitative and quantitative analyses of the 15 basic artificial dyes in fishery products due to its fastness, simplicity and relatively high sensitivity.

  3. Near Surface Gas Simulator (NSGS): A Visual Basic program to improve the design of near-surface gas geochemistry surveys above CO2 geological storage sites

    2009-04-01

    If CO2 were to leak from a geological storage site and be released to the atmosphere, where would it occur and how large would the leak be in terms of dimension and flow rate? There are many options available to monitor storage sites, including deep and shallow geophysical or geochemical methods, biological markers, or remote sensing techniques, each with its advantages and disadvantages. However only the direct measurement of CO2 at the earth's surface, that is soil gas or gas flux analyses, can give a definitive answer to these questions. Considering that these methods involve point measurements, the question has be raised regarding the sampling density that would be needed to locate a leak above a storage site, or, conversely, to ensure that a leak does not exist. To address this issue we have written a program in Visual Basic which uses highly-detailed, gridded synthetic data (with user-defined gas leakage areas) to study the link between sampling density and anomaly size and to find a sampling strategy which minimises the number of samples collected while maximizing the probability that an anomaly (i.e. a leak) will be found. At the beginning of a run the user is asked to define the location, size, and intensity of leakage areas; these areas are then superimposed on a grid (1 x 1 m step size) of normally-distributed background CO2 flux values. Then the user is asked to provide a series of sampling densities (for example, x = 10, 50, 100, 500, and 1000 samples km-2) and the number of simulations that must be conducted for each sampling density (e.g. y = 100). The program then uses a nested loop structure whereby the synthetic dataset is randomly subsampled at the sampling density "x" for a total of "y" times - each of these smaller datasets is then analysed statistically and spatially using subroutines from the programs Statistica and Surfer, and the resultant data from each simulation for that "x" sampling density is combined to define its statistical

    Endoscopic diagnosis of gastrointestinal tumors consists of the following processes: (i) detection; (ii) differential diagnosis; and (iii) quantitative diagnosis (size and depth) of a lesion. Although detection is the first step to make a diagnosis of the tumor, the lesion can be overlooked if an endoscopist has no knowledge of what an early-stage 'superficial lesion' looks like. In recent years, image-enhanced endoscopy has become common, but white-light endoscopy (WLI) is still the first step for detection and characterization of lesions in general clinical practice. Settings and practice of routine esophagogastroduodenoscopy (EGD) such as use of antispasmodics, number of endoscopic images taken, and observational procedure are customarily decided in each facility in each country and are not well standardized. Therefore, in the present article, we attempted to outline currently available evidence and actual Japanese practice on gastric cancer screening using WLI, and provide tips for detecting EGC during routine EGD which could become the basis of future research.

    Full Text Available Objective -- As a first step in gathering evidence, this study surveyed school libraries and examined the services those libraries provide in relation to the Universal Basic Education (UBE program at a primary level. The purpose of this paper is to explore these UBE factors in relation to school libraries in Oyo State, Nigeria.Methods -- A questionnaire was sent to the 33 schools which have a library and information centre staffed by a teacher-librarian, in order to examine library services and the views of those providing them. The questionnaire covers library space, categories of library resources, student activities during library visits, mobile library services, and the teacher-librarians’ perception of the adequacy of the collection and the challenges in the use of library.Results -- Questionnaires were returned by 30 teacher-librarians out of 33, a response rate of 91%. Although pupils across each local government area have the chance to visit school libraries, the system of one short visit per week is inadequate for developing a universal interest in reading and in study skills. Staff responsible for the libraries consider many of the resources to be inadequate or outdated and stock is depleted as pupils borrow books, leaving fewer for those who follow.Conclusions -- As a first step to implementing evidence based practice, this paper describes the primary school library system in Nigeria and provides evidence on how it operates in Oyo State. Teacher-librarians who staff the libraries confirm the inadequacies in the system. They perceive collections to be inadequate and confirm that some pupils in the state have only limited access to library resources. Respondents also believe that they need further training, particularly in computer and information literacy.

    A national survey was conducted to assess immunization practices and tuberculosis screening methods for animal care and research workers in biomedical settings throughout the United States. Veterinarians (n = 953) were surveyed via a web-based mechanism; completed surveys (n = 308) were analyzed. Results showed that occupational health and safety programs were well-developed, enrolling veterinary, husbandry, and research staff at rates exceeding 90% and involving multiple modalities of health assessments and risk communication for vaccine-preventable diseases. Most (72.7%) institutions did not store serum samples from animal research personnel. More than half of the institutions housed nonhuman primates and maintained tuberculosis screening programs, although screening methods varied. Immunization protocols included various recommended or required vaccines that differed depending on job duties, type of institution, and nature of scientific programs. A single case of an identified vaccine-preventable illness in a laboratory worker was noted. Tetanus toxoid was the predominant vaccine administered (91.7%) to animal care and research workers, followed by hepatitis B (54.8%), influenza (39.9%), and rabies (38.3%). For some immunization protocols, an inconsistent rationale for administration was evident. Indications that animal care and research workers are unprotected from work-related etiologic agents did not emerge from this survey; rather, existing guidelines from the Advisory Committee on Immunization Practices and available biologics seem sufficient to address most needs of the laboratory animal research community. Institutions should commit to performance-based standards in parallel with context-specific risk assessment methods to maintain occupational health and safety programs and practices appropriate to their needs.

  10. Inequity of healthcare utilization on mammography examination and Pap smear screening in Thailand: Analysis of a population-based household survey

    Science.gov (United States)

    2017-01-01

    Healthcare in Thailand is not equally distributed, and not all people can equally access healthcare resources even if they are covered by health insurance. To examine factors associated with the utilization of mammography examination for breast cancer and Pap smear screening for cervical cancer, data from the national reproductive health survey conducted by the National Statistical Office of Thailand in 2009 was examined. The survey was carried out on 15,074,126 women aged 30–59 years. The results showed that the wealthier respondents had more mammograms than did the lower-income groups. The concentration index was 0.144. The data on Pap smears for cervical cancer also showed that the wealthier respondents were more likely to have had a Pap smear than their lower-income counterparts. The concentration index was 0.054. Determinants of mammography examination were education, followed by health welfare and wealth index, whereas the determinants of Pap smear screening were wealth index, followed by health welfare and education. The government should support greater education for women because education was associated with socioeconomic status and wealth. There should be an increase in the number of screening campaigns, mobile clinics, and low-cost mammograms and continued support for accessibility to mammograms, especially in rural areas and low-income communities.

    In Japan, the field of Basic Sciences encompasses clinical, academic, and translational research, as well as the teaching of medical sciences, with both an MD and PhD typically required. In this study, it was hypothesized that the characteristics of a Basic Sciences career path could offer the professional advancement and personal fulfillment that many female medical doctors would find advantageous. Moreover, encouraging interest in Basic Sciences could help stem shortages that Japan is experiencing in medical fields, as noted in the three principal contributing factors: premature resignation of female clinicians, an imbalance of female physicians engaged in research, and a shortage of medical doctors in the Basic Sciences. This study examines the professional and personal fulfillment expressed by Japanese female medical doctors who hold positions in Basic Sciences. Topics include career advancement, interest in medical research, and greater flexibility for parenting. A cross-sectional questionnaire survey was distributed at all 80 medical schools in Japan, directed to 228 female medical doctors whose academic rank was assistant professor or higher in departments of Basic Sciences in 2012. Chi-square tests and the binary logistic regression model were used to investigate the impact of parenthood on career satisfaction, academic rank, salary, etc. The survey response rate of female physicians in Basic Sciences was 54.0%. Regardless of parental status, one in three respondents cited research interest as their rationale for entering Basic Sciences, well over twice other motivations. A majority had clinical experience, with clinical duties maintained part-time by about half of respondents and particularly parents. Only one third expressed afterthoughts about relinquishing full-time clinical practice, with physicians who were parents expressing stronger regrets. Parental status had little effect on academic rank and income within the Basic Sciences, CONCLUSION

    There is now a requirement for every doctor in the UK to obtain patient feedback for revalidation. This can be an onerous and time-consuming task. The objective of this study was to evaluate a novel electronic patient feedback method in an outpatient lithotripsy service setting. Between September 2013 and January 2014, 100 patients attending an outpatient lithotripsy service in Oxford were asked to complete a selection of pre-approved NHS questions about the service they had received. Questions were presented on a tablet device (iPad™) and answered using the touch screen. Departmental staff were unaware of the questions in the survey. Patients were asked to complete the survey by an independent research nurse. Questions were created online in a free-to-use web-based survey application and presented on the tablet device in a user-friendly format via an application. Data were uploaded via wifi™ to the online system. Data were viewed, automatically analysed and displayed graphically. The age range of the patients surveyed was 20-80 years of age. All 100 patients completed the survey without difficulty. All patients answered every question. Data could be automatically viewed, analysed and presented graphically. This method of collecting patient feedback proved to be rapid and efficient. The feedback highlighted a high patient satisfaction with the lithotripsy service. A touch screen tablet device is an efficient and effective method of collecting truly objective patient feedback. This method of patient feedback could be employed in other clinical environments to collect data for revalidation purposes.

    2015-06-01

    An automated multi-analyte screening method for the identification and quantification of 92 drugs and metabolites based on on-line solid-phase extraction-high-performance liquid chromatography-diode array detection technique was developed and successfully validated. In addition, a database with 870 entries including UV-spectra, relative/retention times and response factors of toxicologically relevant compounds was created. Plasma samples (0.2 mL) were treated with methanol, diluted with buffer and on-line extracted (Strata X, 20 ×2 mm, 25 µm) at pH 9. Analytical separation was carried out on a Gemini NX column (150 ×4.6 mm, 3 µm) using gradient elution with acetonitrile-water (90:10,v/v) and 0.05 m potassium dihydrogen phosphate buffer (pH 2.3). Linear calibration curves with correlation coefficients ≥0.9950 were obtained for 78 analytes. As an additional benefit, the newly developed method allows the quantification of 42 analytes (e.g. antidepressants, neuroleptics and anticonvulsants) in a concentration range suitable for therapeutic drug monitoring. Limits of quantitation ranged from 0.02 mg/L (chlordiazepoxide) to 3.4 mg/L (mexiletine). Inter- and intra-day precisions of quality control samples (low/high) were better than 15% (zolpidem) and accuracy (bias) ranged from -11% (opipramol, venlafaxine) to 11% (venlafaxine, trazodone). Tests for carry-over and sample stability under different storage conditions were also performed and stability was adequate. Four cases of poisoning analysis are presented.

    We automated portions of the QuantiFERON-TB Gold In-Tube test (QFT-GIT) and assessed its quality when performed concurrently with the tuberculin skin test (TST) among U.S. Air Force basic military trainees (BMTs). The volume of blood collected for QFT-GIT was monitored. At least one of the three tubes required for QFT-GIT had blood volume outside the recommended 0.8- to 1.2-mL range for 688 (29.0%) of 2,373 subjects who had their blood collected. Of the 2,124 subjects who had TST and QFT-GIT completed, TST was positive for 0.6%; QFT-GIT was positive for 0.3% and indeterminate for 2.0%. Among 2,081 subjects with completed TST and determinate QFT-GIT results, overall agreement was 99.5% but positive agreement was 5.6%. Specificity among the 1,546 low-risk BMTs was identical (99.7%). Indeterminate QFT-GIT results were 2.7 times more likely when mitogen tubes contained >1.2 mL blood than when containing 0.8- to 1.2-mL blood. Automation can facilitate QFT-GIT completion, especially if the recommended volume of blood is collected. Mycobacterium tuberculosis infection prevalence among BMTs based on TST and QFT-GIT is similar and low. Selectively testing those with significant risk may be more appropriate than universal testing of all recruits. Reprint & Copyright © 2014 Association of Military Surgeons of the U.S.

    Regular screening is considered the most effective method to reduce the mortality and morbidity associated with breast cancer. Nevertheless, contradictory evidence about screening mammograms has led to periodic changes and considerable variations among different screening guidelines. This study is the first to examine the immediate impact of the 2009 US Preventive Services Task Force (USPSTF) guideline modification on physician recommendation of mammograms. The study included visits by women aged 40 years and older without prior breast cancer from the National Ambulatory and Medical Care Survey 2008-2010. Bivariate and multiple logistic regressions were used to determine the factors associated with mammography recommendation. Approximately 29,395 visits were included and mammography was recommended during 1350 visits; 50-64-year-old women had 72% higher odds, and 65-74-year-old women had twice the odds of getting a mammogram recommendation compared with 40-49-year-old women in 2009. However, there was no difference in recommendation by age groups in 2008 and 2010. Obstetricians and gynecologists did not modify their recommendation behavior in 2009, unlike all other specialists who reduced their recommendation for 40-49-year-old women in 2009. Other characteristics associated with mammogram recommendations were certain patient comorbidities, physician specialty and primary care physician status, health maintenance organization status of the clinic, and certain visit characteristics. This study demonstrated a temporary effect of the USPSTF screening guideline change on mammogram recommendation. However, in light of conflicting recommendations by different guidelines, the physicians erred toward the more rigorous guidelines and did not permanently reduce their mammogram recommendation for women aged 40-49 years.

    Routine colorectal screening, decreases in incidence, and advances in treatment have lowered colorectal cancer mortality rates over the past three decades. Nevertheless, it remains the second most common cause of cancer death amongst men and women combined in U.S. Most cases of colon cancer are diagnosed at a late stage leading to poor survival outcomes for patients. After extensive research of publically available data, it would appear that the state of Connecticut does not have available state-wide data on patient wait times for routine colonoscopy screening. Furthermore, there are no publicly available, or Connecticut-specific, reports on Medicaid participation rates for colorectal screening amongst gastroenterologists (GI) in Connecticut. In 2012, the American Cancer Society report on Colorectal Cancer Screening Rates confirmed barriers to health-care access and disparities in health outcomes and survival rates for colon cancer patients based on race, ethnicity, and low socioeconomic status. Given this information, one could conjecture that low Medicaid participation rates among GIs could potentially have a more severe impact on health-care access and outcomes for underserved populations. At present, funding and human resources are being employed across the state of Connecticut to address bottlenecks in colorectal cancer screening. More specifically, patient navigation and outreach programs are emerging and expanding to address the gaps in services for hard-to-reach populations and the medically underserved. Low Medicaid participation rates and increased wait times for colonoscopy screening may impair the efficacy of colorectal cancer patient navigation and outreach efforts and potentially funding for future interventions. In this study, we report the results of our secret-shopper telephone survey comprising of 93 group and independent gastroenterologist (GI) practices in different counties of Connecticut.

    Full Text Available Background and objective It has been proven that increase of the awareness level of lung cancer prevention and control could enhance participation of lung cancer screening of lung cancer high risk group. The aim of this study is to investigate the awareness level of lung cancer prevention and control and the effect of individual characteristics on lung cancer awareness, and to provide evidence for comprehensive lung cancer prevention in high risk areas of lung cancer. Methods Staffs of Tianjin Dagang Oil Field who participate low dose CT (LDCT lung cancer screening by cluster sampling or according to voluntary principle were surveyed, data of lung cancer awareness were collected by questionnaire. Results A total of 1,633 valid questionnaires were collected. The average age of respondents was 60.08±6.58. Most participants were males (82.2% while female only accounted for 17.8%. The proportions of awareness about lung cancer in China, risk factors, screening methods and the knowledge of health examination were 64.5%, 77.1%, 43.7%, 49.6% respectively. Result of multiple logistic regression analysis showed that education level, smoking (pack-year, age, prior tuberculosis were the influencing factors of lung cancer awareness with adjusted Ors for education and age level as of 0.567 (95%CI: 0.439-0.733 and 1.373 (95%CI: 1.084-1.739 respectively. 80.3% of the participants can accept health examination once a year, while the ability to pay the medical expenses was not high. The influencing factors of health examination willingness were gender, age, income, the knowledge of lung cancer. Conclusion Education level and smoking affect the awareness of lung cancer prevention and control, health education for lung cancer should be conducted especially in population with low education level. Comprehensive lung cancer control in high risk areas should combined lung cancer screening, tobacco control and health education.

    The purpose of the survey is to promote the international research cooperation projects from the survey stage, via demonstration research stage to the diffusion stage. Field surveys have been conducted to find out the needs of energy saving and environmental technology for the efficient consumption of petroleum in the developing countries with mass-consumption of petroleum in the future. The survey was conducted in the Philippines in the FY 1996. Next developing themes were proposed. The first theme was developing method of sugar plant. The magnesia method has been developed as a basic technology for cleaning sugar solution process instead of using lime. By the recycling method, the waste cake amount can be remarkably reduced. The second theme was electron beam exhaust gas treatment by a dry method of simultaneous desulfurization and denitrification of high concentration SOx and NOx in the fertilizer production plants. The third theme was the energy saving technology for SOx reduction of heating furnace for iron-steel by using an ultra energy saving-type regenerative burner. The last theme was chlorine bypass technology in cement industry, which would become an advanced technology development for the use of chlorine containing fuels in the near future. 40 refs., 36 figs., 79 tabs.

    Chan, Y T

    1995-01-01

    Since the study of wavelets is a relatively new area, much of the research coming from mathematicians, most of the literature uses terminology, concepts and proofs that may, at times, be difficult and intimidating for the engineer. Wavelet Basics has therefore been written as an introductory book for scientists and engineers. The mathematical presentation has been kept simple, the concepts being presented in elaborate detail in a terminology that engineers will find familiar. Difficult ideas are illustrated with examples which will also aid in the development of an intuitive insight. Chapter 1 reviews the basics of signal transformation and discusses the concepts of duals and frames.

    Haemoglobinopathies are the most inherited disorders worldwide including Saudi Arabia which can be preventable with application of screening programmers. Ministry of Health in Saudi Arabia had initiated premarital screening program (PMS) in all country regions. The aim of this study was to explore the impact of the PMS program and genetic counseling on couples at risk for thalassaemia and sickle cell anima in an area of the country with high hemoglobinopathy prevalence. A total of 129 candidates identified by PMS to be at risk were included. Out of this cohort, 98% proceeded with marriage. Culture pressure was the main reason in more than 48%. Over a period of 4 years, these marriages resulted in 15 diseased children. Although most of the candidates did not receive genetic counseling yet, the concept of genetic counseling was liked by most of them. This study showed some early benefits of the PMS in prevention of the targeted diseases and the program helped in early detection of the disease in their offspring.

    The purpose of this study was to investigate the distribution of 10 rare red blood groups in Chinese Nanjing population, so as to provide compatible rare blood to patients and to create a donor data bank. Jk (a-b-) (Kidd) phenotypes were detected by urea, while H-(H), GPA-(MNS), GPC-(Gerbich), i+ (Ii) and Lub-(Lutheran) phenotypes were detected by monoclonal, polyclonal antibodies with U type 96 well microplate technology. The screening of Jsb- and k-(Kell), Fya-(Duffy), Ok-(Ok), s-(MNS) and Dib-(Digeo) phenotypes were performed by polymerase chain reaction. The results showed that 2 Jk (a-b-) out of 40337 donation samples and 3 Fy (a-b+) out of 1782 donation samples were found, while no other rare blood phenotypes (H-, GPA-, GPC-, Lub-, Ok-, s-, Jsb-, k-, Dib- and i+) were detected. It is concluded that the frequencies of Jk (a-b-) and Fya(a-b+) are 0.0049% and 0.168% respectively. No more rare blood phenotype was found in this screening.

    Full Text Available Abstract Background In this study we evaluated the usefulness of a free self-test for screening albuminuria in the general population. Methods Dutch adults were invited by the Dutch Kidney Foundation to order a free albuminuria self-test, consisting of three semi quantitative dipstick tests, via the Internet. Results were classified in negative, low-positive and high-positive. In case of a positive test result, the tester was recommended to visit a GP for supplementary examination and/or treatment. Participants of the programme were sent a questionnaire for evaluation by e-mail eight weeks after receiving the self-test. Results During the first 30 days of the self-test programme, 996,927 self-tests were ordered. In total, 71,714 participants completed the questionnaire: 79% had a negative test result and 21% had a positive test result (20% low-positive and 1% high-positive. Of the positive testers, 25% visited a GP after testing for albuminuria. Among the 3,983 participants who visited a GP, 193 new diseases were detected: 25 chronic renal failure, 152 hypertension and 31 diabetes mellitus. Conclusion Using a free self-test for screening albuminuria in the general population resulted in a large response and a number of newly detected diseases. However, we found a very high percentage of positive testers of which probably a large part is false positive. Furthermore, only a small part of the positive testers visited a GP for additional examination and/or treatment. The efficiency of such a campaign could be increased by embedding the testing in health care to reduce the number of false-positive results and to ensure follow-up and treatment in case of a positive test result.

    Full Text Available Abstract Background Perceived racial discrimination is one factor which may discourage ethnic minorities from using healthcare. However, existing research only partially explains why some persons do accept health promotion messages and use preventive care, while others do not. This analysis explores 1 the psychosocial characteristics of those, within disadvantaged groups, who identify their previous experiences as racially discriminatory, 2 the extent to which perceived racism is associated with broader perspectives on societal racism and powerlessness, and 3 how these views relate to disadvantaged groups' expectation of mistreatment in healthcare, feelings of mistrust, and motivation to use care. Methods Using survey data from 576 African-American women, we explored the prevalence and predictors of beliefs and experiences related to social disengagement, racial discrimination, desired and actual racial concordance with medical providers, and fear of medical research. We then used both sociodemographic characteristics, and experiences and attitudes about disadvantage, to model respondents' scores on an index of personal motivation to receive breast cancer screening, measuring screening knowledge, rejection of fatalistic explanatory models of cancer, and belief in early detection, and in collaborative models of patient-provider responsibility. Results Age was associated with lower motivation to screen, as were depressive symptoms, anomie, and fear of medical research. Motivation was low among those more comfortable with African-American providers, regardless of current provider race. However, greater awareness of societal racism positively predicted motivation, as did talking to others when experiencing discrimination. Talking was most useful for women with depressive symptoms.

    Full Text Available Background : Current psychometric measures of childhood trauma history generally fail to assess the relational-socioecological context within which childhood maltreatment occurs, including the relationship of abusers to abused persons, the emotional availability of caregivers, and the respondent's own thoughts, feelings, and actions in response to maltreatment. Objective : To evaluate a computerized approach to measuring the relational-socioecological context within which childhood maltreatment occurs. Method : The psychometric properties of a Childhood Attachment and Relational Trauma Screen (CARTS were evaluated as a retrospective survey of childhood maltreatment history designed to be appropriate for completion by adults. Participants were undergraduates (n=222, an internet sample (n=123, and psychiatric outpatients (n=30. Results : The internal reliability, convergent, and concurrent validity of the CARTS were supported across samples. Paired differences in means and correlations between rated item-descriptiveness to self, mothers, and fathers also accorded with findings of prior attachment and maltreatment research, illustrating the utility of assessing the occurrence and effects of maltreatment within a relational-socioecological framework. Conclusions : Results preliminarily support a new survey methodology for assessing childhood maltreatment within a relational-socioecological framework. Further psychometric evaluation of the CARTS is warranted.

    Full Text Available Abstract Background Despite evidence that breast cancer screening reduces morbidity and mortality, until recently most women have not undergone regular mammogram examinations in Korea. We aimed to identify factors associated with use of breast cancer screening services. Methods The Health Promotion Knowledge, Attitude and Practice survey (HP-KAP survey is part of the Third Korea National Health and Nutrition Examination Survey 2005 (KNHANES III, a nationwide health survey in Korea. Of 7,802 individuals who participated in the HP-KAP survey, 4,292 were female. Of these, 2,583 were women aged at least 40 years and without a history of breast cancer; these women were included in this study. Information about breast cancer screening participation was obtained from the responses to questionnaires. The overall rate of regular breast cancer screening was measured. Factors that affect participation in a breast cancer screening program were identified using multiple logistic regression analysis. Results Among women aged at least 40 years, 30.4% complied with breast screening recommendations. Age of at least 65 years (adjusted odds ratio, aOR 0.61, 95% CI: 0.42-0.88, education level (no [ref], elementary school [aOR 1.51, 95% CI: 1.06-1.47], middle/high school [aOR 1.99, 95% CI: 1.36-2.92], university/higher [aOR 2.73, 95% CI: 1.71-4.35], private health insurance (aOR 1.42, 95% CI: 1.71-4.35, attitude towards screening tests (aOR 0.18, 95% CI: 0.14-0.23, self-reported health status of 'fair' (aOR 1.26 95% CI: 1.00-1.58, and smoking (aOR 0.52, 95% CI: 0.35-0.79 were associated with the rate of regular breast cancer screening Conclusions To increase the nationwide breast cancer screening rate, more attention should be given to underrepresented groups, particularly the elderly, those with a low education level, smokers, and those with a negative attitude towards screening tests. These issues highlight the need for a new emphasis in health education

Tanito Harum which owns the mining right. The area for survey is approximately 10km west of Tenggarong city, the capital of Kabupaten Kutai, East Kalimantan Province which is northeast part of Kalimantan island of Indonesia. The field survey was divided into the geological/boring survey and the survey of conditions for underground mining development and the infrastructure. This survey made it clear that in the underground mining of PDL7A seam, assuming the minable coal reserve to be 6.81 million tons, it is possible to produce raw coal of 0.5 million tons/year by adopting the longwall pick mining. The raw coal is all prepared, and the yield is 80%. Accordingly, the production of product coal is 0.4 million tons/year.

    Background: The European Community recommends mammography, cervical and colorectal cancer screening programmes. In Italy, cancer screening programmes have been included in the Basic Healthcare Parameters (Livelli Essenziali di Assistenza since 2001. Full national coverage of a population-based organized screening programme has been planned for in Italy and is being implemented. Since 2005, the Ministry of Health - Department of Prevention has formally charged The National Centre for Screening Monitoring (Osservatorio Nazionale Screening –ONS- with monitoring and promoting screening programmes nationwide. Participation of target populations is a key indicator of the impact and efficacy of a screening programme in reducing cancer mortality.

    Methods: Attendance of invitees is one of the indicators calculated every year in the quality control of Italian screening programmes. Data collection is organized by means of a structured questionnaire, sent by ONS to the referent for data collection in each Region, who then returns the completed questionnaires to the Regional Centre. Questionnaires are then sent to the National Centre. Logical and epidemiologic checks are performed at both levels. Every year ONS publishes reports on the results of the surveys. A feasibility study for a National data warehouse based on individual records is in progress. The national survey “Multiscopo sulle famiglie” and the Passi Study (Progetti delle Aziende Sanitarie per la Salute in Italia provided additional information regarding spontaneous preventive health care activities in the Italian population.

    Results: Mammography screening: In 2006, 78.2% of Italian women aged 50-69 lived in areas where organised screening was in place (theoretical extension, however, the distribution of the screening activity is not uniform (higher in Northern/Central Italy compared with Southern

    Deciding about undergoing prenatal screening is difficult, as it entails risks, potential loss and regrets, and challenges to personal values. Shared decision making and decision aids (DAs) can help pregnant women give informed and values-based consent or refusal to prenatal screening, but little is known about factors influencing the use of DAs. The objective of this study was to identify the influence of psychosocial factors on pregnant women's intention to use a DA for prenatal screening for Down syndrome (DS). We also added health literacy variables to explore their influence on pregnant women's intention. We conducted a survey of pregnant women in the province of Quebec (Canada) using a Web panel. Eligibility criteria included age >18 years, >16 weeks pregnant, low-risk pregnancy, and having decided about prenatal screening for the current pregnancy. We collected data based on an extended version of the Theory of Planned Behavior assessing 7 psychosocial constructs (intention, attitude, anticipated regret, subjective norm, descriptive norm, moral norm, and perceived control), 3 related sets of beliefs (behavioral, normative, and control beliefs), 4 health literacy variables, and sociodemographics. Eligible women watched a video depicting the behavior of interest before completing a Web-based questionnaire. We performed descriptive, bivariate, and ordinal logistic regression analyses. Of the 383 eligible pregnant women who agreed to participate, 350 pregnant women completed the Web-based questionnaire and 346 were retained for analysis (completion rate 350/383, 91.4%; mean age 30.1, SD 4.3, years). In order of importance, factors influencing intention to use a DA for prenatal screening for DS were attitude (odds ratio, OR, 9.16, 95% CI 4.02-20.85), moral norm (OR 7.97, 95% CI 4.49-14.14), descriptive norm (OR 2.83, 95% CI 1.63-4.92), and anticipated regret (OR 2.43, 95% CI 1.71-3.46).

    ERT is an economic instrument which helps power companies achieve emission reduction compliance cost-effectively. This paper presents the basics of ERT with reference to trading concepts, types of systems and types of emissions. The paper also describes the state of the Canadian energy market regarding greenhouse gases (GHG), nitrogen oxides, sulphur dioxide and volatile organic compounds. The association between ERT and district energy is also explained. By 2010, the global market for GHG trading is expected to be worth $10 billion to $3 trillion U.S. Canada has committed to reducing its GHG to 6 per cent below 1990 levels by 2012, but currently emits 705 Mt per year. This is expected to increase to 770 Mt by 2010. Therefore, in order to meet its commitment, GHGs will have to be reduced 200 Mt per year. Canada is currently considering ratifying the Kyoto agreement and a trading system is being developed. There are several abatement technologies currently under consideration for district energy systems, including adding scrubbers, improving efficiency, and fuel switching. The marginal cost of abatement was also discussed. tabs., figs.

    We aimed to disentangle the effects of obesity and mobility limitation on cervical and breast cancer screening among community dwelling women. The data source was the French national Health and Disability Survey - Household Section, 2008. The Body Mass Index (BMI) was used to categorize obesity status. We constructed a continuous score of mobility limitations to assess the severity of disability (Cronbach's alpha = 0.84). Logistic regressions were performed to examine the association between obesity, mobility limitations and the use of Pap test (n = 8 133) and the use of mammography (n = 7 561). Adjusted odds ratios were calculated (AOR). Interaction terms between obesity and the disability score were included in models testing for effect modifications. Compared with non-obese women, the odds of having a Pap test in the past 3 years was 24% lower in obese women (AOR = 0.76; 95% CI: 0.65 to 0.89), the odds of having a mammogram in the past 2 years was 23% lower (AOR = 0.77; 95% CI: 0.66 to 0.91). Each time the disability score was 5 points higher, the odds of having a Pap test decreases by 20% (AOR = 0.96; 95% CI: 0.94 to 0.98), the odds of having a mammogram decreases by 25% (AOR = 0.95; 95% CI: 0.94 to 0.97). There was no significant interaction between obesity and disability score. Obesity and mobility limitation are independently associated with a lower likelihood of cervical and breast cancer screening. Protective outreach and follow-up are necessary to reduce inequalities and thus to reduce health disparities in these vulnerable and high-risk populations of obese women with disabilities.

    Full Text Available Abstract Background A discrete choice experiment (DCE is a preference survey which asks participants to make a choice among product portfolios comparing the key product characteristics by performing several choice tasks. Analyzing DCE data needs to account for within-participant correlation because choices from the same participant are likely to be similar. In this study, we empirically compared some commonly-used statistical methods for analyzing DCE data while accounting for within-participant correlation based on a survey of patient preference for colorectal cancer (CRC screening tests conducted in Hamilton, Ontario, Canada in 2002. Methods A two-stage DCE design was used to investigate the impact of six attributes on participants' preferences for CRC screening test and willingness to undertake the test. We compared six models for clustered binary outcomes (logistic and probit regressions using cluster-robust standard error (SE, random-effects and generalized estimating equation approaches and three models for clustered nominal outcomes (multinomial logistic and probit regressions with cluster-robust SE and random-effects multinomial logistic model. We also fitted a bivariate probit model with cluster-robust SE treating the choices from two stages as two correlated binary outcomes. The rank of relative importance between attributes and the estimates of β coefficient within attributes were used to assess the model robustness. Results In total 468 participants with each completing 10 choices were analyzed. Similar results were reported for the rank of relative importance and β coefficients across models for stage-one data on evaluating participants' preferences for the test. The six attributes ranked from high to low as follows: cost, specificity, process, sensitivity, preparation and pain. However, the results differed across models for stage-two data on evaluating participants' willingness to undertake the tests. Little within

    A discrete choice experiment (DCE) is a preference survey which asks participants to make a choice among product portfolios comparing the key product characteristics by performing several choice tasks. Analyzing DCE data needs to account for within-participant correlation because choices from the same participant are likely to be similar. In this study, we empirically compared some commonly-used statistical methods for analyzing DCE data while accounting for within-participant correlation based on a survey of patient preference for colorectal cancer (CRC) screening tests conducted in Hamilton, Ontario, Canada in 2002.

    Full Text Available Abstract Background The prevalence and predictors of functional status and disability of elderly people have been studied in several European countries including Spain. However, there has been no population-based study incorporating the International Classification of Functioning, Disability and Health (ICF framework as the basis for assessing disability. The present study reports prevalence rates for mild, moderate, and severe/extreme disability by the domains of activities and participation of the ICF. Methods Nine populations surveyed in previous prevalence studies contributed probabilistic and geographically defined samples in June 2005. The study sample was composed of 503 subjects aged ≥75 years. We implemented a two-phase screening design using the MMSE and the World Health Organization-Disability Assessment Schedule 2nd edition (WHO-DAS II, 12 items as cognitive and disability screening tools, respectively. Participants scoring within the positive range of the disability screening were administered the full WHO-DAS II (36 items; score range: 0-100 assessing the following areas: Understanding and communication, Getting along with people, Life activities, Getting around, Participation in society, and Self-care. Each disability area assessed by WHO-DAS II (36 items was reported according to the ICF severity ranges (No problem, 0-4; Mild disability, 5-24; Moderate disability, 25-49; Severe/Extreme disability, 50-100. Results The age-adjusted disability prevalence figures were: 39.17 ± 2.18%, 15.31 ± 1.61%, and 10.14 ± 1.35% for mild, moderate, and severe/extreme disability, respectively. Severe and extreme disability prevalence in mobility and life activities was three times higher than the average, and highest among women. Sex variations were minimal, although life activities for women of 85 years and over had more severe/extreme disability as compared to men (OR = 5.15 95% CI 3.19-8.32.

    Following repeated import bans imposed by Saudi Arabia on livestock originated from Somalia due to suspicion of Rift Valley fever (RVF) presence and the severe socio-economic consequences of this, it was imperative for the Somaliland government to carry out surveillance activities in order to determine the status of transboundary diseases in its territory. A GIS computer software (Arcview) was used to overcome the lack of lists of sampling sites due to the high mobility of pastoral nomadic herds in the study area. This method proved very convenient and flexible for the random selection of sampling sites and thus the compliance with the requirements by the World Organisation for Animal Health (OIE) for statistically valid methods if the surveillance outcome is to meet international recognition and acceptance. Screening in Somaliland in 2001 and in Puntland in 2003 which targeted mainly sheep and goats aged 1-2 years (97% of surveyed animals) revealed no signs compatible with the disease but an overall sero-prevalence of 2+/-0.02% (90/4570) and 5+/-0.3% (206/4050), respectively. The spatial distribution showed clusters of high sero-prevalence located mostly in the Nugal Valley. This trend was confirmed by the follow-up survey implemented in Somaliland in 2004 with a herd prevalence of 80+/-6% and a within-herd prevalence up to 50% located again in the Nugal Valley. This result suggests the maintenance and increase of RVF virus activity in the valley. In addition conditions favourable to the breeding and survival of the vector population and the high density of livestock make the Nugal Valley an area of high risk for a RVF outbreak where sentinel herds will be placed.

    Background Most US adolescents do not meet guidelines of at least 60 daily minutes of moderate- to vigorous-intensity physical activity. Additionally, sedentary behaviors among this age group are of increasing concern. This study examined the association of movement behaviors with cardiovascular fitness among US adolescents. Methods Data from the 2012 NHANES National Youth Fitness Survey were used to assess the association of movement behaviors (physical activity, sedentary time, screen time) with cardiovascular fitness among adolescent males and females. Multiple logistic regressions were used to test the independent and interactive effects of movement behaviors on cardiovascular fitness. Results Among females, physical activity was directly associated with cardiovascular fitness; no significant association was observed between sedentary behaviors and CVF. Among males, sedentary time moderated the relationship between physical activity and cardiovascular fitness, such that a significant, direct association was only observed among those with high sedentary time (OR: 5.01, 95% CI: 1.60, 15.70). Conclusions Results from this cross-sectional analysis suggest that among female US adolescents, physical activity, but not sedentary behavior, is associated with cardiovascular fitness. Among males, the interaction between physical activity and sedentary time seems to be important for cardiovascular fitness. Longitudinal studies are warranted to confirm these findings.

    Dietetics contributes to life-long, sustainable health and optimal life quality of people. The knowledge of the nutritional state can be informative and normative in order to optimize personal care. The aims of this study were to summarize the relevant legislative considerations of nourishing the elderly in different long-term residential social institutions and to screen the nutritional state of those living there. No investigation of this type has ever been carried out in Hungary or in central eastern Europe before. We used the malnutrition universal screening tool (MUST) screening program for the evaluation of nutritional status. Our survey was done in 20 Hungarian nursing homes in 2006. The sample (n=1381) was representative of regional distribution and number of residents. In our study population 38.2% of the patients were endangered in point of malnutrition. The results of our survey call attention to the elevated number of elderly people at risk of malnutrition in nursing homes. As malnutrition has serious consequences regarding also quality of life, nutritional screening of nursing home residents is not only a basic economical interest, but is also in full harmony with the idea "not only to feed, but to nourish" and it is a basic moral duty.

    Planar chip technology has strongly facilitated the progress towards fully automated electrophysiological systems that, in contrast to the traditional patch clamp technology, have the capability of parallel compound testing. The throughput has been increased from testing below 10 compounds per day to a realized capacity approaching high throughput levels. Many pharmaceutical companies have implemented automated planar chip electrophysiology in their drug discovery process, particularly at the levels of lead optimization, secondary screening and safety testing, whereas primary screening is generally not performed. In this review, we briefly discuss the technology and give examples from selected NeuroSearch ion channel programs, where one of the systems, the QPatch, has been evaluated for use in lead optimization and primary screening campaigns, where high information content was a requirement.

    Full Text Available Obviously, since the challenges of life change with time, education should aim at bringing up children with hearing impairment to face these changes and make necessary adjustment in their lives for successful living. Hence education programs and service provisions should therefore be dynamic. To realise these important functions, programs and services designed for the students with hearing impairment in an inclusive education setting should not be on exemption, since the society itself is dynamic in many respects, its fundamental needs equally change with time which hitherto makes societal objective changes also, owing to advancement in scientific inventions, innovation in trends and practices of inclusive education. Bearing this in mind, this paper sought to ascertain the level of provision and availability of basic facilities and services necessary for the successful inclusion of students with hearing impairment. The survey focused on the availability and use of assistive technology devices by the hearing impaired students, recruitment and training of teaching and supportive staff, communication strategies adapted by the teachers, medical and socials services .Data were collected using a Likert-like questionnaire from the sampled secondary schools in the states under investigation. The researcher analysed the data using the Pearson Product Moment Correlation co-efficient. The results revealed that much is yet to be put in place in the states under study for the successful inclusion of students with hearing impairment into inclusive education setting.

    The effects of technical parameters, such as screen-film combinations, antiscatter grids, processing conditions and X-ray beam qualities, on the average glandular tissue dose of radiation were analyzed under two exposure conditions: The standard radiographic condition for an RMI 156 phantom at each facility (Standard Radiographic Condition). The radiographic condition needed to obtain a radiographic density of 1.20 to 1.40 with an RMI 156 phantom (Canonical Radiographic Condition). The analysis included 208 dose measurements at 104 facilities. The results showed that the average glandular tissue dose depends strongly on the grid types and screen-film combinations used. There were also significant differences in radiographic density between the Standard Radiographic Condition and the Canonical Radiographic Condition. This analysis of the technical parameters affecting the glandular tissue dose will be useful in establishing a standardized mammographic breast cancer screening system. (author)

    2008-11-01

    Full Text Available Abstract Background Since July 1998 all Dutch women (± 200,000/y are screened for red cell antibodies, other than anti-RhesusD (RhD in the first trimester of pregnancy, to facilitate timely treatment of pregnancies at risk for hemolytic disease of the fetus and newborn (HDFN. Evidence for benefits, consequences and costs of screening for non-RhD antibodies is still under discussion. The screening program was evaluated in a nation-wide study. As a part of this evaluation study we investigated, according to the sixth criterium of Wilson and Jüngner, the acceptance by pregnant women of the screening program for non-RhD antibodies. Methods Controlled longitudinal survey, including a prenatal and a postnatal measurement by structured questionnaires. Main outcome measures: information satisfaction, anxiety during the screening process (a.o. STAI state inventory and specific questionnaire modules, overall attitude on the screening program. Univariate analysis was followed by standard multivariate analysis to identify significant predictors of the outcome measures. Participants: 233 pregnant women, distributed over five groups, according to the screening result. Results Satisfaction about the provided information was moderate in all groups. All screen- positive groups desired more supportive information. Anxiety increased in screen- positives during the screening process, but decreased to basic levels postnatally. All groups showed a strongly positive balance between perceived utility and burden of the screening program, independent on test results or background characteristics. Conclusion Women highly accept the non-RhD antibody screening program. However, satisfaction about provided information is moderate. Oral and written information should be provided by obstetric care workers themselves, especially to screen-positive women.

    Objective To learn about the awareness of vaccination knowledge among pregnant women in an attempt to provide basis for improving its publicity and promoting health education. Methods Self-designed questionnaires were used to conduct the survey among 358 randomly selected pregnant women who taking pregnancy examination in No. 323 PLA Hospital from January to June in 2014, including participants’ basic information, awareness of basic vaccination knowledge and demands for vaccination knowledge. Likert Scale was used and statistical analysis was conducted. Results Participants being younger or with lower education level, migrant workers and self-employed individuals had relatively lower level of awareness, but the difference among groups was not significant (all P>0. 05). The main ways to learn about vaccination were publicity in community of the hospital (94. 41%) and information from others (89. 66%). The differences in the attitudes towards ‘wanting to learn vaccination knowledge’ ,‘willing to participate lecture’ , and‘supporting the whole vaccination for children’ were not significant among participants with different culture and occupation (all P>0. 05). Conclusion Efforts are needed to concentrate on key population, to improve the awareness of vaccination among pregnant women, and to carry out kinds of health education, so as to spread vaccination knowledge better and improve vaccination rate among children.%目的:了解孕妇对预防接种知识的认知情况,为做好宣传工作、实施健康教育提供依据。方法自行设计调查问卷,随机对2014年1至6月在解放军第三二三医院进行孕期检查的358名女性进行问卷调查,内容包括基本信息、预防接种基础知识以及预防接种知识需求等,采用记分制,并对调查结果进行统计分析。结果低年龄、低学历、农民工和个体商户的认知程度较低,但组间比较差异均无统计学意义(均P>0.05);孕妇获得

    1996-01-01

    greatest responsibility lies with medical and health care institutions and those who determine the priorities of these institutions. Patient and physician barriers to mass cancer screening can be addressed by institutional support. If the quality of care delivered by providers, group practices, managed-care organizations, and HMOs is assessed with priority given to the regularity and consistency with which basic screening procedures are performed, cancer screening will undoubtedly receive greater attention in the clinic. Medical institutions must collaborate to develop standards for cancer screening with attention to the cost-effectiveness of various screening techniques to determine how limited resources can best be spent in cancer control. Such efforts should keep in mind "that a very small change implemented over a broad population may have a greater effect in absolute numbers than a large level of change applied in a small segment of the population."

    Attempts to modify gravity in the infrared typically require a screening mechanism to ensure consistency with local tests of gravity. These screening mechanisms fit into three broad classes; we investigate theories which are capable of exhibiting more than one type of screening. Specifically, we focus on a simple model which exhibits both Vainshtein and kinetic screening. We point out that due to the two characteristic length scales in the problem, the type of screening that dominates depends on the mass of the sourcing object, allowing for different phenomenology at different scales. We consider embedding this double screening phenomenology in a broader cosmological scenario and show that the simplest examples that exhibit double screening are radiatively stable.

    Compare public perceptions and intentions to undergo colorectal cancer screening tests following detailed information regarding CT colonography (CTC; after non-laxative preparation or full-laxative preparation), optical colonoscopy (OC) or flexible sigmoidoscopy (FS). A total of 3,100 invitees approaching screening age (45-54 years) were randomly allocated to receive detailed information on a single test and asked to return a questionnaire. Outcomes included perceptions of preparation and test tolerability, health benefits, sensitivity and specificity, and intention to undergo the test. Six hundred three invitees responded with valid questionnaire data. Non-laxative preparation was rated more positively than enema or full-laxative preparations [effect size (r) = 0.13 to 0.54; p < 0.0005 to 0.036]; both forms of CTC and FS were rated more positively than OC in terms of test experience (r = 0.26 to 0.28; all p-values < 0.0005). Perceptions of health benefits, sensitivity and specificity (p = 0.250 to 0.901), and intention to undergo the test (p = 0.213) did not differ between tests (n = 144-155 for each test). Despite non-laxative CTC being rated more favourably, this study did not find evidence that offering it would lead to substantially higher uptake than full-laxative CTC or other methods. However, this study was limited by a lower than anticipated response rate. (orig.)

    Fusarium species isolated from Belgian maize were screened for their ability to produce fusarin C, fusaric acid, fumonisins B1 (FB1), FB2 and FB3 in maize grains. First, cultivation of Fusarium species in Myro liquid medium allowed overcoming the shortage of the standard of fusarin C on the market. All Fusarium verticillioides produced much higher contents of mycotoxins in Myro compared to Fusarium graminearum or Fusarium venenatum. The optimization of the LC-MS/MS method resulted in low limits of detection and quantification for fusarin C, fusaric acid, FB1, FB2 and FB3 determination in maize grains. Its application for screening the potential toxin production ability evidenced that the concentrations of the analytes were significantly increased at various levels when F. verticillioides strains were cultivated in maize grains and reached 441 mg kg(-1) for fusaric acid, 74 mg kg(-1) for fusarin C, 1,301 mg kg(-1) for FB1, 367 mg kg(-1) for FB2 and 753 mg kg(-1) for FB3.

    Human papillomavirus (HPV) vaccine was approved for girls aged 9-24 years in 2006 to prevent HPV infection and cervical cancer. The Parental Human Papillomavirus Survey (PHPVS) was framed on theoretical constructs of the health belief model (HBM) and developed to survey parents regarding their HPV knowledge, attitudes, and intent to vaccinate. We evaluated the psychometric properties of the PHPVS using classical item analysis and exploratory factor analysis (EFA) among a sample of 200 parents/caregivers. The EFA yielded a 4-factor unidimensional model that explained between 62% and 68% of the total variance depending on the extraction method used. The estimated Cronbach's alpha for the PHPVS was .96. The PHPVS is a reliable measure of HPV knowledge, attitudes, and intent to vaccinate.

The aims of this study were to compare the characteristics of women who got a Pap-test during the mass media campaign, carried out in an Italian region by broadcasts advertising, and two years later and to identify the determinants of knowledge of cervical cancer etiology and of the adherence to the mass media campaign. Methods. A cross-sectional survey was carried out through a self-administered questionnaire. Results. A total of 8570 randomly selected women were surveyed, 823 of these had a Pap-test during the mass media campaign period and 7747 two years later. Higher educational level, being not married, and living in urban areas were the main independent characteristics associated with a higher level of knowledge of cervical cancer etiology, although a previous treatment following a Pap smear abnormality was the strongest predictor (OR = 2.88; 95% CI: 2.43–3.41. During the campaign period women had the Pap-test more frequently as a consequence of the mass media campaign (OR = 8.28; 95% CI; 5.51–12.45. Conclusions. Mass media campaign is a useful tool to foster cervical screening compliance; however, its short-term effect suggests repeating it regularly.

In 2008, births given by mothers under PMTCT in five selected hospitals of Health Region 4 of Thailand between 2002 and 2006 were identified from the registered data and the medical records, were reviewed. Their homes were visited to collect the data. Among 138 mothers and 143 children studied, nobody died. Forty-four were healthy 91 experienced mild episode of various infections and allergy within the past three months, one was admitted for pneumonia, two were HIV-positive, 53 were negative and the other 88 had no final blood tested In the Denver Developmental Screening Test (DDST), all parameters were minimal, less than 5%. Overall, the suspected delay development is around 15.4%. For nutritional status assessment by height for age (HFA), weight for age (WFA) and weight for height (WFH) reported a quarter (23.1%) was stunting whereas 12.6% were thin and 5.6% were wasting, respectively. Among the study PMTCT children, serious morbidity was rare. Nutritional deficiency was more common than delayed development.

    The aims of this study were to assess the diagnostic value of the weight-to-height ratio (WHtR) for the detection of obesity and metabolic syndrome (MS) in Korean children and adolescents, and to determine the advantages of WHtR as a population-based screening tool in comparison with other obesity indicators, such as body mass index (BMI) and waist circumference (WC). We performed a cross-sectional analysis of data from 3057 children and adolescents (1625 boys, 1332 girls) aged 10–19 years who were included in the fifth Korean National Health and Nutrition Examination Survey (KNHANES, 2010–2012) up to the second year of the sixth KNHANES (2013–2014). Receiver operation characteristic (ROC) curves were generated to determine the optimal cutoff value and accuracy of WHtR for predicting individual obesity indicators or more than two non-WC components of MS. The area under the ROC curve (AUC) is a measure of the diagnostic power of a test. A perfect test will have an AUC of 1.0, and an AUC equal to 0.5 means that the test performs no better than chance. The optimal WHtR cutoff for the evaluation of general obesity and central obesity was 0.50 in boys and 0.47–0.48 in girls, and the AUC was 0.9. Regarding the assessment of each MS risk factor, the optimal WHtR cutoff was 0.43–0.50 in boys and 0.43–0.49 in girls, and these cutoffs were statistically significant only for the detection of high triglyceride and low High-density lipoprotein (HDL) cholesterol levels. When a pairwise comparison of the AUCs was conducted between WHtR and BMI/WC percentiles to quantify the differences in power for MS screening, the WHtR AUC values (boys, 0.691; girls, 0.684) were higher than those of other indices; however, these differences were not statistically significant (boys, p = 0.467; girls, p = 0.51). The WHtR cutoff value was 0.44 (sensitivity, 67.7%; specificity, 64.6%) for boys and 0.43 (sensitivity, 66.4%; specificity, 66.9%) for girls. There was no significant

    1992-07-01

    Ortony and Turner's (1990) arguments against those who adopt the view that there are basic emotions are challenged. The evidence on universals in expression and in physiology strongly suggests that there is a biological basis to the emotions that have been studied. Ortony and Turner's reviews of this literature are faulted, and their alternative theoretical explanations do not fit the evidence. The utility of the basic emotions approach is also shown in terms of the research it has generated.

    A survey on perkinsosis was performed involving 15 locations scattered along the Galician coast (NW Spain) and four clam species with high market value (Ruditapes decussatus, Ruditapes philippinarum, Venerupis corrugata and Polititapes rhomboides). The prevalence of Perkinsus parasites was estimated by PCR using genus-specific primers. The highest percentage of PCR-positive cases for perkinsosis corresponded to clams R. decussatus and V. corrugata, while lower values were detected in R. philippinarum and no case was found in P. rhomboides. The discrimination of Perkinsus species was performed by PCR-RFLP and by a new PCR-DGGE method developed in this study. Perkinsus olseni was identified in every clam species, except in P. rhomboides, using both PCR-DGGE and PCR-RFLP. Additionally, Perkinsus chesapeaki was only detected by PCR-DGGE infecting two Manila clams R. philippinarum from the same location, reporting the first case in Galicia. P. chesapeaki identification was further confirmed by in situ hybridisation assay and phylogenetic analysis of ITS region and LSU rDNA.

    2007-01-01

    Basic Electromagnetism and Materials is the product of many years of teaching basic and applied electromagnetism. This textbook can be used to teach electromagnetism to a wide range of undergraduate science majors in physics, electrical engineering or materials science. However, by making lesser demands on mathematical knowledge than competing texts, and by emphasizing electromagnetic properties of materials and their applications, this textbook is uniquely suited to students of materials science. Many competing texts focus on the study of propagation waves either in the microwave or optical domain, whereas Basic Electromagnetism and Materials covers the entire electromagnetic domain and the physical response of materials to these waves. Professor André Moliton is Director of the Unité de Microélectronique, Optoélectronique et Polymères (Université de Limoges, France), which brings together three groups studying the optoelectronics of molecular and polymer layers, micro-optoelectronic systems for teleco...

    2014-05-01

    We present a brief overview of nuclear multifragmentation reaction. Basic formalism of canonical thermodynamical model based on equilibrium statistical mechanics is described. This model is used to calculate basic observables of nuclear multifragmentation like mass distribution, fragment multiplicity, isotopic distribution and isoscaling. Extension of canonical thermodynamical model to a projectile fragmentation model is outlined. Application of the projectile fragmentation model for calculating average number of intermediate mass fragments and the average size of the largest cluster at different bound, differential charge distribution and cross-section of neutron-rich nuclei of different projectile fragmentation reactions at different energies are described. Application of nuclear multifragmentation reaction in basic research as well as in other domains is outlined.

    Hepatocellular carcinoma (HCC) is one of the most frequently diagnosed tumour diseases throughout the world. In the vast majority of cases those affected are high-risk patients with chronic viral hepatitis and/or liver cirrhosis, which means there is a clearly identifiable target group for HCC screening. With resection, transplantation, and interventional procedures for local ablation, following early diagnosis curative treatment options are available with which 5-year survival rates of over 60% can be reached. Such early diagnosis is a reality only in a minority of patients, however, and in the majority of cases the disease is already in an advanced stage at diagnosis. One of the objects of HCC screening is diagnosis in an early stage when curative treatment is still possible. Precisely this is achieved by screening, so that the proportion of patients treated with curative intent is decisively higher. There is not yet any clear evidence as to whether this leads to a lowering of the mortality of HCC. As lower mortality is the decisive indicator of success for a screening programme the benefit of HCC screening has so far been neither documented nor refuted. Nonetheless, in large regions of the world it is the practice for high-risk patients to undergo HCC screening in the form of twice-yearly ultrasound examination and determination of AFP. (orig.)

Volume 1 was called Band Theory and Transport Properties in the first edition, but the subject has broadened to such an extent that Basic Properties is now a more suitable title. Seven chapters have been rewritten by the original authors. However, twelve chapters are essentially new, with the bulk of this work being devoted to important current topics which give this volume an almost encyclopaedic form. The first three chapters discuss various aspects of modern band theory and the

The reason it is so interesting to me is that the term 'back to basics' implies reverting to a simpler time in life - when by just sticking to the rules, life became easier. However, with decontamination this is not actually true.

    2015-01-01

    Full Text Available Background: Many ocular conditions when detected at an early age such as basic school age through vision screening are amenable to interventional measures. Despite this, there are no eye screening programs for school children in Ghana. Objective: The study set out to determine the prevalence of ocular morbidity among basic school children in the Kwabre East District of Ghana. Methods: A descriptive, cross-sectional survey was carried out in March 2014. A multi-stage random sampling technique was used to select school children aged 6-16 years from five randomly selected schools in the district. Ocular history and basic ocular examinations were carried out on the children that were sampled. Results: A total of 456 children were examined; they comprised 170 (27.3% males and 286 (62.7% females with a mean age of 12.6 ± 2.25. 215 (47.1% of the school children had various ocular morbidities. Refractive error was found to be the most predominant ocular morbidity among 120 (26.3% school children, followed by allergic conjunctivitis 79 (17.3%. A total of 445 (97.6% of the participants had a visual acuity (VA of 6/5-6/12, 8 (1.8% had a VA of < 6/12-6/36 and 3 (0.7% had a VA of 6/60 - NPL in their right eye. Only 12.8% of the school children had knowledge about refractive errors. Conclusion: Uncorrected refractive error and allergic conjunctivitis were the leading ocular morbidities found among school children in this sample. A routine ocular health assessment among basic school children is recommended to prevent any visual impairment.

    The present survey was intended to enhance accuracy of analysis and interpretation of the geological structures in the northern and north-western parts of this area, and the status of coal seam existence. The survey used the most part of the earthquake exploration data obtained in fiscal 1988, and parts of the earthquake exploration data obtained in fiscal 1983 and fiscal 1985 in the vicinities thereof, and incorporated a new treatment method to perform re-analysis. The quaternary deposit seam has thickness of 80 to 610 m, and the Palaeogene deposit seam has thickness of 600 to 1600 m as a whole. The structure of the foundation bed is nearly parallel with the structure of the top of a coal seam in the Palaeogene deposit seam, having a distance of 300 m between the seams. The surveys combining the test drillings having been done to date and the physical exploration estimates that the coal seam groups are distributed over the entire area of Ariake Sea. Possibility has heightened, that the coal seam groups may spread over the land area. The collapsed fault passing east-west the northern most area of the Ariake Sea and having drop of 200 to 300 m forms the northern boundary of the Miike coal field. However, the coal seam groups are estimated to spread north of the coal field as a sedimentary basin, and continue to the northern side of the fault. (NEDO)

    We aimed to investigate the use of placebos (e.g. saline injections) and non-specific treatments (e.g. vitamin supplements in individuals without a relevant deficiency) among physicians working in private practices in Germany, and how such use is associated with the belief in and the use of complementary and alternative treatments, and basic professional attitudes. A four-page questionnaire was sent to nationwide random samples of general practitioners (GP), internists and orthopaedists working in private practices. The response rate was 46% (935 of 2018). 24% of GPs, 44% of internists and 57% of orthopaedists had neither used pure placebos nor non-specific therapies in the previous 12 months. 11% percent of GPs, 12% of internists and 7% of orthopaedists had exclusively used pure placebos; 30%, 33% and 26%, respectively, had exclusively used non-specific therapies; 35%, 12% and 9% had used both. Age, sex and agreement to the statement that physicians should harness placebo effects were not significantly associated with any pattern of use. Exclusive use of pure placebos was associated with being a GP, being an internist, and having unorthodox professional views. In addition to these three factors, a lower use of CAM therapies and a wish for having more time was associated with the exclusive use of non-specific therapies. Among physicians using both pure placebo and non-specific therapies, heterodox views were also somewhat more pronounced. However, associations were particularly strong for being a GP (Odds ratio 11.6 (95%CI 6.41; 21.3)) and having orthodox views (Odds ratio 0.10 (95%CI 0.06; 0.18)) among this group. In conclusion, the use of placebos and non-specific treatments varies strongly between medical specialties and is associated with basic professional attitudes. The findings support the view that the use of placebos and, in particular, of non-specific therapies is primarily a coping behaviour for difficult and uncertain situations.

    Müller-Kirsten, Harald J W

    2013-01-01

    Statistics links microscopic and macroscopic phenomena, and requires for this reason a large number of microscopic elements like atoms. The results are values of maximum probability or of averaging. This introduction to statistical physics concentrates on the basic principles, and attempts to explain these in simple terms supplemented by numerous examples. These basic principles include the difference between classical and quantum statistics, a priori probabilities as related to degeneracies, the vital aspect of indistinguishability as compared with distinguishability in classical physics, the differences between conserved and non-conserved elements, the different ways of counting arrangements in the three statistics (Maxwell-Boltzmann, Fermi-Dirac, Bose-Einstein), the difference between maximization of the number of arrangements of elements, and averaging in the Darwin-Fowler method. Significant applications to solids, radiation and electrons in metals are treated in separate chapters, as well as Bose-Eins...

    Gallo, A

    2011-01-01

    RF electronics deals with the generation, acquisition and manipulation of high-frequency signals. In particle accelerators signals of this kind are abundant, especially in the RF and beam diagnostics systems. In modern machines the complexity of the electronics assemblies dedicated to RF manipulation, beam diagnostics, and feedbacks is continuously increasing, following the demands for improvement of accelerator performance. However, these systems, and in particular their front-ends and back-ends, still rely on well-established basic hardware components and techniques, while down-converted and acquired signals are digitally processed exploiting the rapidly growing computational capability offered by the available technology. This lecture reviews the operational principles of the basic building blocks used for the treatment of high-frequency signals. Devices such as mixers, phase and amplitude detectors, modulators, filters, switches, directional couplers, oscillators, amplifiers, attenuators, and others are d...

    Blyth, T S

    2002-01-01

    Basic Linear Algebra is a text for first year students leading from concrete examples to abstract theorems, via tutorial-type exercises. More exercises (of the kind a student may expect in examination papers) are grouped at the end of each section. The book covers the most important basics of any first course on linear algebra, explaining the algebra of matrices with applications to analytic geometry, systems of linear equations, difference equations and complex numbers. Linear equations are treated via Hermite normal forms which provides a successful and concrete explanation of the notion of linear independence. Another important highlight is the connection between linear mappings and matrices leading to the change of basis theorem which opens the door to the notion of similarity. This new and revised edition features additional exercises and coverage of Cramer's rule (omitted from the first edition). However, it is the new, extra chapter on computer assistance that will be of particular interest to readers:...

  11. Basic electronic circuits

    CERN Document Server

    Buckley, P M

    1980-01-01

    In the past, the teaching of electricity and electronics has more often than not been carried out from a theoretical and often highly academic standpoint. Fundamentals and basic concepts have often been presented with no indication of their practical appli­ cations, and all too frequently they have been illustrated by artificially contrived laboratory experiments bearing little relationship to the outside world. The course comes in the form of fourteen fairly open-ended constructional experiments or projects. Each experiment has associated with it a construction exercise and an explanation. The basic idea behind this dual presentation is that the student can embark on each circuit following only the briefest possible instructions and that an open-ended approach is thereby not prejudiced by an initial lengthy encounter with the theory behind the project; this being a sure way to dampen enthusiasm at the outset. As the investigation progresses, questions inevitably arise. Descriptions of the phenomena encounte...

    Nadkarni, M G

    2013-01-01

    This is an introductory book on Ergodic Theory. The presentation has a slow pace and the book can be read by any person with a background in basic measure theory and metric topology. A new feature of the book is that the basic topics of Ergodic Theory such as the Poincare recurrence lemma, induced automorphisms and Kakutani towers, compressibility and E. Hopf's theorem, the theorem of Ambrose on representation of flows are treated at the descriptive set-theoretic level before their measure-theoretic or topological versions are presented. In addition, topics around the Glimm-Effros theorem are discussed. In the third edition a chapter entitled 'Additional Topics' has been added. It gives Liouville's Theorem on the existence of invariant measure, entropy theory leading up to Kolmogorov-Sinai Theorem, and the topological dynamics proof of van der Waerden's theorem on arithmetical progressions.

    2013-09-01

    After WTG Morton's first public demonstration in 1846 of use of ether as an anaesthetic agent, for many years anaesthesiologists did not require a machine to deliver anaesthesia to the patients. After the introduction of oxygen and nitrous oxide in the form of compressed gases in cylinders, there was a necessity for mounting these cylinders on a metal frame. This stimulated many people to attempt to construct the anaesthesia machine. HEG Boyle in the year 1917 modified the Gwathmey's machine and this became popular as Boyle anaesthesia machine. Though a lot of changes have been made for the original Boyle machine still the basic structure remains the same. All the subsequent changes which have been brought are mainly to improve the safety of the patients. Knowing the details of the basic machine will make the trainee to understand the additional improvements. It is also important for every practicing anaesthesiologist to have a thorough knowledge of the basic anaesthesia machine for safe conduct of anaesthesia.

    Patient experience and clinical quality, which are represented by preventive care measures such as cancer screening, are both widely used for the evaluation of primary care quality. The aim of this study was to examine the association between patient experience and cancer screening uptake among women in a Japanese population. We conducted a cross-sectional mail survey. The questionnaire was sent to 1000 adult female residents randomly selected from a basic resident register in Yugawara town, Kanagawa, Japan. We assessed patient experience of primary care using a Japanese version of Primary Care Assessment Tool (JPCAT) and uptake of breast and cervical cancer screening. The overall response rate was 46.5%. Data were analyzed for 190 female participants aged 21-74 years who had a usual source of primary care. Multivariate logistic regression analyses revealed that the JPCAT total score was significantly associated with uptake of breast cancer screening [odds ratio (OR) per 1 standard deviation increase = 1.63; 95% CI 1.11-2.41], but not with uptake of cervical cancer screening (OR per 1 standard deviation increase = 1.47; 95% CI 0.97-2.24). Patient experience of primary care was associated with uptake of breast cancer screening among Japanese women. The results of our study might support the argument that patient experience of primary care and the clinical process of preventive care, such as breast cancer screening, are linked.

    Objective To screen a high stable host bacterium that can repeatedly transfer the culture and meet the re -quirements of pilot-scale technology and to select the optimal basic fermentation medium for this engineering bacterium . Methods A plasmid pSVK-HBVA was transformed into several different E. coli competent cells and the morphology of ex -tracted plasmids was monitored by agarose gel electrophoresis , with the continuous passage method used for testing the sta -bility of the engineered bacterium. Based on the above -mentioned results , the engineered bacterium that harbored a plasmid with the highest yield and stability was selected as the original seed to establish the three seed lots and identify the seed lots. From LB, TB, M9 ( glycerol) and M9 ( glucose) we selected the optimal medium which could generate the highest plasmid yield. Results We found that plasmid pSVK-HBVA showed similar stability to conventional plasmid DNA harbored in E. coli XL10-Gold host bacterium, which could transfer 30 passages without recombination or fragment loss and meet the requirements of the pilot process . LB was the optimal basic fermentation medium that could generate the highest plasmid volumetric yield 5. 5 mg/L. Conclusion The host bacterium E. coli XLIO-Gold is more conducive to amplification of self replication HBV therapeutic DNA vaccine pSVK-HBVA, and the optimal basic fermentation medium for this engineered bacterium is LB.%目的 为乙肝治疗性可复制型DNA疫苗质粒pSVK-HBVA筛选稳定性高,能多次传代的宿主菌,以满足中试工艺的要求,同时对该工程菌最适的基础发酵培养基进行选择.方法 将质粒pSVK-HBVA分别转化几种不同的大肠杆菌感受态细胞并提取质粒,通过琼脂糖凝胶电泳检测质粒的形态结构,连续传代法对工程菌的稳定性进行检测;选取质粒含量最高和稳定性最好的工程菌作为原始种子,按照2010版要求建立工程菌的三级种子批,并对种子批

  7. Catalyst in Basic Oleochemicals

    Full Text Available Currently Indonesia is the world largest palm oil producer with production volume reaching 16 million tones per annum. The high crude oil and ethylene prices in the last 3 – 4 years contribute to the healthy demand growth for basic oleochemicals: fatty acids and fatty alcohols. Oleochemicals are starting to replace crude oil derived products in various applications. As widely practiced in petrochemical industry, catalyst plays a very important role in the production of basic oleochemicals. Catalytic reactions are abound in the production of oleochemicals: Nickel based catalysts are used in the hydrogenation of unsaturated fatty acids; sodium methylate catalyst in the transesterification of triglycerides; sulfonic based polystyrene resin catalyst in esterification of fatty acids; and copper chromite/copper zinc catalyst in the high pressure hydrogenation of methyl esters or fatty acids to produce fatty alcohols. To maintain long catalyst life, it is crucial to ensure the absence of catalyst poisons and inhibitors in the feed. The preparation methods of nickel and copper chromite catalysts are as follows: precipitation, filtration, drying, and calcinations. Sodium methylate is derived from direct reaction of sodium metal and methanol under inert gas. The sulfonic based polystyrene resin is derived from sulfonation of polystyrene crosslinked with di-vinyl-benzene. © 2007 BCREC UNDIP.

We have selected a few of the most significant contributions to the fields of basic and clinical immunology published between October 2001 and October 2002. Our choice of topics in basic immunology included the description of T-bet as a determinant factor for T(H)1 differentiation, the role of the activation-induced cytosine deaminase gene in B-cell development, the characterization of CD4(+)CD25(+) regulatory T cells, and the use of dynamic imaging to study MHC class II transport and T-cell and dendritic cell membrane interactions. Articles related to clinical immunology that were selected for review include the description of immunodeficiency caused by caspase 8 deficiency; a case series report on X-linked agammaglobulinemia; the mechanism of action, efficacy, and complications of intravenous immunoglobulin; mechanisms of autoimmunity diseases; and advances in HIV pathogenesis and vaccine development. We also reviewed two articles that explore the possible alterations of the immune system caused by spaceflights, a new field with increasing importance as human space expeditions become a reality in the 21st century.

    South Pacific Islands played important roles in People’s Republic of China’s strategies of unification and development. Chinese migration into these islands started from the 19th century with concentration on only economic activities. Now Chinese Diaspora in these islands now expanded both in quantity and in spatial distribution, which was further strengthened by the arrival of more and more new Chinese immigrants. This article try to make a general survey to Chinese Diaspora in South Pacific islands, with special concerns with their immigration history, socio-eco-nomic situation, the evolution of the Chinese community, Chinese education and political participations.%南太平洋群岛在中国统一战略、发展战略中占有重要的位置。自19世纪中叶开始便有华人定居在南太平洋群岛,形成小型华商中心。至今,华人足迹遍布南太平洋岛国,而且不断有新的华人移民涌入。本文从华人移民史、社会经济状况、华社、华文教育、政治参与等几个方面论述南太平洋岛国华侨华人的概况。

    Lieberman, E; Faich, G A; Simon, P R; Mullan, R J

    1981-04-03

    Rhode Island law requires that rubella serological screening be done for most female marriage license applicants. To evaluate the effect of the law, 203 rubella-susceptible women detected through premarital screening over a four-month period in 1978 were surveyed. Of those responding, 37% had been immunized, 21% were pregnant or infertile, and 42% were eligible for immunization but had not received vaccine. Premarital immunization occurred most frequently when physicians advised and directly offered vaccine. A survey of primary care physicians indicated that 24% immunized none of their rubella-susceptible patients detected by premarital screening.

    Die Entscheidung, einen zeit- bzw. ereignisgesteuerten Ansatz für ein Echtzeitsystem zu verwenden, ist schwierig und sehr weitreichend. Weitreichend vor allem deshalb, weil diese beiden Ansätze mit äußerst unterschiedlichen Kontrollflussabstraktionen verknüpft sind, die eine spätere Migration zum anderen Paradigma sehr schwer oder gar unmöglich machen. Wir schlagen daher die Verwendung einer Zwischendarstellung vor, die unabhängig von der jeweils verwendeten Kontrollflussabstraktion ist. Für diesen Zweck verwenden wir auf Basisblöcken basierende Atomic Basic Blocks (ABB) und bauen darauf ein Werkzeug, den Real-Time Systems Compiler (RTSC) auf, der die Migration zwischen zeit- und ereignisgesteuerten Systemen unterstützt.

  7. Anisotropic hydrodynamics -- basic concepts

    CERN Document Server

    Florkowski, Wojciech; Ryblewski, Radoslaw; Strickland, Michael

    2013-01-01

    Due to the rapid longitudinal expansion of the quark-gluon plasma created in relativistic heavy ion collisions, potentially large local rest frame momentum-space anisotropies are generated. The magnitude of these momentum-space anisotropies can be so large as to violate the central assumption of canonical viscous hydrodynamical treatments which linearize around an isotropic background. In order to better describe the early-time dynamics of the quark gluon plasma, one can consider instead expanding around a locally anisotropic background which results in a dynamical framework called anisotropic hydrodynamics. In this proceedings contribution we review the basic concepts of the anisotropic hydrodynamics framework presenting viewpoints from both the phenomenological and microscopic points of view.

    2012-01-01

    This textbook is aimed at engineering students who are likely to come across magnetics applications in their professional practice. Whether designing lithography equipment containing ferromagnetic brushes, or detecting defects in aeronautics, some basic knowledge of 21st century magnetism is needed. From the magnetic tape on the pocket credit card to the read head in a personal computer, people run into magnetism in many products. Furthermore, in a variety of disciplines tools of the trade exploit magnetic principles, and many interdisciplinary laboratory research areas cross paths with magnetic phenomena that may seem mysterious to the untrained mind. Therefore, this course offers a broad coverage of magnetism topics encountered more often in this millenium, revealing key concepts on which many practical applications rest. Some traditional subjects in magnetism are discussed in the first half of the book, followed by areas likely to spark the curiosity of those more interested in today’s technological achi...

    1987-12-01

    Of the 319 radiologists who responded to a survey concerning mammography practices, 50% were employed in a private hospital and 26% in a private office. Film-screen mammography was used most often (54%) followed by xeromammography (30%) and a combination of film-screen and xeromammography (16%). Of the respondents, 62% had changed their method of performing mammography in the last 10 years. Of these, 50% had switched from xeromammography to film-screen, 23% from direct film to film-screen, 15% from direct film to xeromammography, and 6% from film-screen to xeromammography. Mammographic equipment had been purchased by 71% of respondents after 1983. Most respondents (71%) monitored mammography equipment doses, usually at 6- to 12-month intervals. Manual breast examinations were done at the time of mammography at 42% of the facilities, and breast self-examination was taught at 32%. For screening, 87.4% used a two-view examination, 92% required the name of a referring physician to whom the report could be sent, 28% accepted self-referred patients, and only 12% charged a reduced fee for screening. Breast sonography was performed by 53% (93% hand-held vs 7% automated), but none used sonography for screening. Only one respondent reported using thermography; three used light scanning. A need for postgraduate mammography courses for radiologists was indicated by 81%, while 69% recommended technologist courses and 64% recommended 1-week fellowships for radiologists.

    The purpose of this project is to reduce environmental load by investigating the recovery/utilization technologies of mine methane gas, to build predictive simulation for the behavioral change in methane gas that is incidental to underground mining, and to reflect the simulation on the optimum mining plan. Performed in the survey this year were the information collection/analysis of the coal and gas resources, exploratory boring for the purpose of grasping the geology, coal bed and gas abundance in the selected survey sites, measurement of coal bed gas reservoir, and the survey of geotechnological features. The operations were as follows; collection of existing geological data and selection of exploratory boring sites for Arrowfield layers and Bowfield layers in the Hunter Valley region. The coal bed gas reservoir and the composition of the coal cores obtained in eight borings this year provided precious gas data along with the survey results performed in the subject sites in the past. In particular, significant data necessary for depth coal development were also obtained in the surrounding mines including the subject survey sites. It was confirmed that the gas reservoir in the coal bed was 8 m{sup 3}/t to 9 m{sup 3}/t on the average. (NEDO)

  17. Debye screening

    Brydges, David C.; Federbush, Paul

    1980-10-01

    The existence and exponential clustering of correlation functions for a classical coulomb system at low density or high temperature are proven using methods from constructive quantum field theory, the sine gordon transformation and the Glimm, Jaffe, Spencer expansion about mean field theory. This is a vindication of a belief of long standing among physicists, known as Debye screening. That is, because of special properties of the coulomb potential, the configurations of significant probability are those in which the long range parts of r -1 are mostly cancelled, leaving an effective exponentially decaying potential acting between charge clouds. This paper generalizes a previous paper of one of the authors in which these results were obtained for a special lattice system. The present treatment covers the continuous mechanics situation, with essentially arbitrary short range forces and charge species. Charge symmetry is not assumed.

    Osteoarthritis (OA) is a prevalent, disabling disorder of the joints that affects a large population worldwide and for which there is no definitive cure. This review provides critical insights into the basic knowledge on OA that may lead to innovative end efficient new therapeutic regimens. While degradation of the articular cartilage is the hallmark of OA, with altered interactions between chondrocytes and compounds of the extracellular matrix, the subchondral bone has been also described as a key component of the disease, involving specific pathomechanisms controlling its initiation and progression. The identification of such events (and thus of possible targets for therapy) has been made possible by the availability of a number of animal models that aim at reproducing the human pathology, in particular large models of high tibial osteotomy (HTO). From a therapeutic point of view, mesenchymal stem cells (MSCs) represent a promising option for the treatment of OA and may be used concomitantly with functional substitutes integrating scaffolds and drugs/growth factors in tissue engineering setups. Altogether, these advances in the fundamental and experimental knowledge on OA may allow for the generation of improved, adapted therapeutic regimens to treat human OA.

    2001-01-01

    rii application of linear operators on a Hilbert space. We begin with a chapter on the geometry of Hilbert space and then proceed to the spectral theory of compact self adjoint operators; operational calculus is next presented as a nat­ ural outgrowth of the spectral theory. The second part of the text concentrates on Banach spaces and linear operators acting on these spaces. It includes, for example, the three 'basic principles of linear analysis and the Riesz­ Fredholm theory of compact operators. Both parts contain plenty of applications. All chapters deal exclusively with linear problems, except for the last chapter which is an introduction to the theory of nonlinear operators. In addition to the standard topics in functional anal­ ysis, we have presented relatively recent results which appear, for example, in Chapter VII. In general, in writ­ ing this book, the authors were strongly influenced by re­ cent developments in operator theory which affected the choice of topics, proofs and exercises. One ...

    Hirschel, Ernst Heinrich

    2015-01-01

    This successful book gives an introduction to the basics of aerothermodynamics, as applied in particular to winged re-entry vehicles and airbreathing hypersonic cruise and acceleration vehicles. The book gives a review of the issues of transport of momentum, energy and mass, real-gas effects as well as inviscid and viscous flow phenomena. In this second, revised edition the chapters with the classical topics of aerothermodynamics more or less were left untouched. The access to some single topics of practical interest was improved. Auxiliary chapters were put into an appendix. The recent successful flights of the X-43A and the X-51A indicate that the dawn of sustained airbreathing hypersonic flight now has arrived. This proves that the original approach of the book to put emphasis on viscous effects and the aerothermodynamics of radiation-cooled vehicle surfaces was timely. This second, revised edition even more accentuates these topics. A new, additional chapter treats examples of viscous thermal surface eff...

    2013-01-01

    There is no doubt that nanoscience will be the dominant direction for technology in this century, and that this science will influence our lives to a large extent as well as open completely new perspectives on all scientific and technological disciplines. To be able to produce optimal nanosystems with tailor-made properties, it is necessary to analyze and construct such systems in advance by adequate theoretical and computational methods. Since we work in nanoscience and nanotechnology at the ultimate level, we have to apply the basic laws of physics. What methods and tools are relevant here? The book gives an answer to this question. The background of the theoretical methods and tools is critically discussed, and also the world view on which these physical laws are based. Such a debate is not only of academic interest but is of highly general concern, and this is because we constantly move in nanoscience and nanotechnology between two extreme poles, between infinite life and total destruction .

    This is a review of the articles dealing with basic science published in recent issues of Archivos de Bronconeumología. Of particular interest with regard to chronic obstructive pulmonary disease were an article on extrapulmonary inflammation and oxidative stress and another on bronchial remodeling. The articles relating to asthma included a review on the use of drugs that block free immunoglobulin-E and an article about the contribution of experimental models to our knowledge of this disease. Two of the most interesting articles on the topic of lung cancer dealt with gene therapy and resistance to chemotherapy. Also notable were 2 studies that investigated ischemia-reperfusion injury. One evaluated tissue resistance to injury while the other analyzed the role played by interleukin-8 in this process. On the topic of pulmonary fibrosis, an article focused on potential biomarkers of progression and prognosis; others dealt with the contribution of experimental models to our understanding of this disorder and the fibrogenic role of transforming growth factor b. In the context of both sleep apnea syndrome and pulmonary infection, studies investigating the role of oxidative stress were published. Finally, 2 studies analyzed the diagnosis and treatment of tuberculosis and other pulmonary infections.

    Full Text Available The goal of grounded theory is to generate a theory that accounts for a pattern of behavior that is relevant and problematic for those involved. The goal is not voluminous description, nor clever verification. As with all grounded theory, the generation of a basic social process (BSP theory occurs around a core category. While a core category is always present in a grounded research study, a BSP may not be.BSPs are ideally suited to generation by grounded theory from qualitative research because qualitative research can pick up process through fieldwork that continues over a period of time. BSPs are a delight to discover and formulate since they give so much movement and scope to the analyst’s perception of the data. BSPs such as cultivating, defaulting, centering, highlighting or becoming, give the feeling of process, change and movement over time. They also have clear, amazing general implications; so much so, that it is hard to contain them within the confines of a single substantive study. The tendency is to refer to them as a formal theory without the necessary comparative development of formal theory. They are labeled by a “gerund”(“ing” which both stimulates their generation and the tendency to over-generalize them.

    2011-09-01

    Gastric cancer (GC) is a world health burden, ranging as the second cause of cancer death worldwide. Etiologically, GC arises not only from the combined effects of environmental factors and susceptible genetic variants but also from the accumulation of genetic and epigenetic alterations. In the last years, molecular oncobiology studies brought to light a number of genes that are implicated in gastric carcinogenesis. This review is intended to focus on the recently described basic aspects that play key roles in the process of gastric carcinogenesis. Genetic variants of the genes IL-10, IL-17, MUC1, MUC6, DNMT3B, SMAD4, and SERPINE1 have been reported to modify the risk of developing GC. Several genes have been newly associated with gastric carcinogenesis, both through oncogenic activation (GSK3β, CD133, DSC2, P-Cadherin, CDH17, CD168, CD44, metalloproteinases MMP7 and MMP11, and a subset of miRNAs) and through tumor suppressor gene inactivation mechanisms (TFF1, PDX1, BCL2L10, XRCC, psiTPTE-HERV, HAI-2, GRIK2, and RUNX3). It also addressed the role of the inflammatory mediator cyclooxygenase-2 (COX-2) in the process of gastric carcinogenesis and its importance as a potential molecular target for therapy.

    Renewable gases such as biogas and biomethane are considered as key energy carrier when the society is replacing fossil fuels with renewable alternatives. In Sweden, almost 80 % of the fossil fuels are used in the transport sector. Therefore, the focus in Sweden has been to use the produced biogas in this sector as vehicle gas. Basic Data on Biogas contains an overview of production, utilisation, climate effects etc. of biogas from a Swedish perspective. The purpose is to give an easy overview of the current situation in Sweden for politicians, decision makers and interested public. 1.4 TWh of biogas is produced annually in Sweden at approximately 230 facilities. The 135 wastewater treatment plants that produce biogas contribute with around half of the production. In order to reduce the sludge volume, biogas has been produced at wastewater treatment plants for decades. New biogas plants are mainly co-digestion plants and farm plants. The land filling of organic waste has been banned since 2005, thus the biogas produced in landfills is decreasing.

    Heinemann, Lutz; Hompesch, Marcus

    2014-01-01

    Until now most of the insulin used in developed countries has been manufactured and distributed by a small number of multinational companies. Beyond the established insulin manufacturers, a number of new players have developed insulin manufacturing capacities based on modern biotechnological methods. Because the patents for many of the approved insulin formulations have expired or are going to expire soon, these not yet established companies are increasingly interested in seeking market approval for their insulin products as biosimilar insulins (BI) in highly regulated markets like the EU and the United States. Differences in the manufacturing process (none of the insulin manufacturing procedures are 100% identical) can lead to insulins that to some extent may differ from the originator insulin. The key questions are if subtle differences in the structure of the insulins, purity, and so on are clinically relevant and may result in different biological effects. The aim of this article is to introduce and discuss basic aspects that may be of relevance with regard to BI. © 2014 Diabetes Technology Society.

    The Gaia all-sky astrometric survey is challenged by several issues affecting the spacecraft stability. Amongst them, we find the focus evolution, straylight and basic angle variations Contrary to pre-launch expectations, the image quality is continuously evolving, during commissioning and the nominal mission. Payload decontaminations and wavefront sensor assisted refocuses have been carried out to recover optimum performance. An ESA-Airbus DS working group analysed the straylight and basic angle issues and worked on a detailed root cause analysis. In parallel, the Gaia scientists have also analysed the data, most notably comparing the BAM signal to global astrometric solutions, with remarkable agreement.

    The Gaia all-sky astrometric survey is challenged by several issues affecting the spacecraft stability. Amongst them, we find the focus evolution, straylight and basic angle variations Contrary to pre-launch expectations, the image quality is continuously evolving, during commissioning and the nominal mission. Payload decontaminations and wavefront sensor assisted refocuses have been carried out to recover optimum performance. An ESA-Airbus DS working group analysed the straylight and basic angle issues and worked on a detailed root cause analysis. In parallel, the Gaia scientists have also analysed the data, most notably comparing the BAM signal to global astrometric solutions, with remarkable agreement. In this contribution, a status review of these issues will be provided, with emphasis on the mitigation schemes and the lessons learned for future space missions where extreme stability is a key requirement.

    Full Text Available INTRODUCTION: HIV premarital screening is one of the practices that is prevalent and compulsory in religious communities of many African countries and is a major health issue that constitutes basic threat to fundamental human right when made mandatory. AIM: This study is therefore tailored towards assessing the awareness, attitude and practice of HIV premarital screening among religious leaders in Ilorin metropolis of Nigeria. METHOD: This study was a descriptive cross sectional survey carried out in 2008. A total of 375 religious leaders were used. Multistage sampling technique involving five stages sampling procedures was used to select participants. The research instrument was structured interviewer administered questionnaire. Results obtained from the questionnaire were analysed using EPI-INFO computer software and data were presented in form of tables, cross tabulation and test of statistical significance. RESULTS: Result showed that the awareness of religious leaders on HIV/AIDS, premarital HIV screening and Voluntary Confidential Counselling and Testing (VCCT was high. Most of the premarital HIV screening was initiated by the religious leaders. Also, majority of leaders made premarital HIV screening compulsory which is against the right of the members. More than half of the respondents said they will conduct marriage without premarital HIV screening and more than half also said that they will conduct marriage if one of the partners is tested positive. Religion was found to influence respondents’ attitude in making premarital HIV screening mandatory, rejection among respondents members on premarital HIV screening and conduction of marriage without premarital HIV screening. CONCLUSION: In as much as premarital HIV screening is good; members should be convinced to do this screening and not to be coerced by these religious leaders, thus, stepping on one of their human right.

  12. Criminal policy: Basic concepts

    2014-01-01

    Full Text Available In the contemporary literature on law, politicology and security, there have been various attempts in both scientific and applied disciplines to define the notion and content of the crime suppression policy. The differences underlying these diverse views are based on the different starting points, i.e. whether the criminal policy is perceived as: 1] a scientific (academic] discipline; b] a practical daily activity of competent state authorities and other relevant bodies; 3] an activity of combating crime as a set of most dangerous human behaviors which imperil the most important personal assets and social values; and 4] an activity aimed at suppressing all types of illegal behavior (felonies, misdemeanors, delinquency, economic crimes, etc]. Some authors view the policy of crime suppression as a scientific discipline which provides for the appropriate use of existing tools in combating crime. Concurrently, on the basis of defined body of knowledge and analysis, the science (including some sciences outside the field of law] suggests relevant measures for efficient suppression of crime. Another conception is based on the idea that criminal policy has a dual meaning, i.e. that it may be understood as: 1] a practical social activity aimed at accomplishing the envisaged goals (also known as a practical dimension of crime policy], and 2] a scientific discipline which explores, analyses and proposes measures of social reaction towards criminal behavior. In practice, criminal policy encompasses a system of purposeful, consciously planned and coordinated social activities aimed at preventing crime and protecting the society at large. When perceived in this way, criminal policy is the basic element of the general public policy in a specific society. Just like the criminal law of an individual state, criminal policy is based on specific principles (governing rules].

    Breast cancer is the main cause of cancer deaths for Hispanic women. This study analyzes the role of functional health literacy on mammography screening behavior and adherence of Hispanic women. Survey data from 722 Mexican American women age 40 and over residing in the Lower Rio Grande Valley of Texas in 2008 were used to estimate logistic regression models to assess the role of functional health literacy on mammography screening behavior and adherence. About 51% of survey respondents had a functional health literacy level deemed as inadequate or marginally functional. After adjusting for other factors, women with adequate health literacy levels were more likely to report to have ever had a mammogram (odds ratio [OR] = 2.92; 95% confidence interval [CI] = 1.62-5.28), to have had a mammogram within the last 2 years (OR = 1.70; 95% CI = 1.14-2.53) or to have had one within the last year (OR = 2.30; 95% CI = 1.54-3.43), compared to women with inadequate or marginally adequate functional health literacy levels. Inadequate/marginal functional health literacy is strongly associated with lower mammography screening. Large improvements in breast cancer control in this population may come from either basic advances in health literacy or by tailored approaches to help women with low literacy navigate local health care systems.

    2005-05-04

    Celebrities often promote cancer screening by relating personal anecdotes about their own diagnosis or that of a loved one. We used data obtained from a random-digit dialing survey conducted in the United States from December 2001 through July 2002 to examine the extent to which adults of screening age without a history of cancer had seen or heard or been influenced by celebrity endorsements of screening mammography, prostate-specific antigen (PSA) testing, or sigmoidoscopy or colonoscopy. The survey response rate was 72% among those known to be eligible and 51% among potentially eligible people accounting for those who could not be contacted. A total of 360 women aged 40 years or older and 140 men aged 50 years or older participated in the survey. Most respondents reported they "had seen or heard a celebrity talk about" mammography (73% of women aged 40 years or older), PSA testing (63% of men aged 50 years or older), or sigmoidoscopy or colonoscopy (52% of adults aged 50 years or older). At least one-fourth of respondents who had seen or heard a celebrity endorsement said that the endorsement made them more likely to undergo mammography (25%), PSA testing (31%), or sigmoidoscopy or colonoscopy (37%).

    Current demographic trends and medical practices raise the question of cancer screening in the elderly, especially those with dementia. Furthermore, studies have suggested that patient with Alzheimer disease showed a reduced risk of cancer. However, this link may be biased by the absence of cancer screening. That's why we conducted a survey to poll general practitioners' (GP) opinion on screening cancer in the elderly. In this study, 304 general practitioners were asked, from May to March 2014, about their cancer screening practices and on the elements influencing it. Eighty-two physicians responded. The rate of response was 29.4%. Forty-nine (60%) GP said practicing cancer screening in the elderly, 60 (64%) thought that screening does not lead to treatment, 51 (62%) GP were not favorable to cancer screening in patients with dementia, 63 (77%) GP thought that there is a lack of recommendations to guide cancer screening in the elderly. Finally, this study shows that cancer screening is less performed in patients with dementia. Further, promote exchange between general practitioners and specialists, by strengthening Cancer and Geriatrics networks, could probably increase cancer screening in the elderly, with or without dementia.

    Screening and postsymptomatic diagnostic testing are often conflated in cancer screening surveillance research. We examined the error in estimated colorectal cancer screening prevalence due to the conflation of screening and diagnostic testing. Using data from the 2008 National Health Interview Survey, we compared weighted prevalence estimates of the use of all testing (screening and diagnostic) and screening in at-risk adults and calculated the overestimation of screening prevalence across sociodemographic groups. The population screening prevalence was overestimated by 23.3%, and the level of overestimation varied widely across sociodemographic groups (median, 22.6%; mean, 24.8%). The highest levels of overestimation were in non-Hispanic white females (27.4%), adults ages 50-54 years (32.0%), and those with the highest socioeconomic vulnerability [low educational attainment (31.3%), low poverty ratio (32.5%), no usual source of health care (54.4%), and not insured (51.6%); all P colorectal cancer screening prevalence was overestimated, and patterns of overestimation often aligned with social and economic vulnerability. These results are of concern to researchers who use survey data from the Behavioral Risk Factor Surveillance System (BRFSS) to assess cancer screening behaviors, as it is currently not designed to distinguish diagnostic testing from screening. Surveillance research in cancer screening that does not consider the impetus for testing risks measurement error of screening prevalence, impeding progress toward improving population health. Ultimately, to craft relevant screening benchmarks and interventions, we must look beyond "what" and "when" and include "why." ©2015 American Association for Cancer Research.

    2016-07-01

    Full Text Available Introduction : Osteoporosis is an illness characterized by the handicapped endurance of the bones, causing an increased risk of fracture. Aim of the study was to establish the level of knowledge about osteoporosis prevention among women screened by bone densitometry and to answer the question whether the level of knowledge is dependent on socio-demographic factors. Material and methods: The research was realized by means of a survey method, a poll technique in 2014. The study involved 292 women aged 51-83. The examined women were patients undergoing bone densitometry in the healthcare centres in Lublin. The osteoporosis knowledge test (OKT, revised 2011 by Phyllis Gendler was used as a research tool. Gathered material was subject to descriptive and statistical analysis. Tukey’s test, t-Student test and variance analysis (ANOVA were all applied. A statistical significance level was set at  = 0.05. Results and conclusions : Respondents presented the basic exercise knowledge (M = 9.97 and low knowledge concerning risk factors, screening and treatment of osteoporosis (M = 7.87. The calcium knowledge remained on an average level (M = 14.03. Better educated women, city inhabitants as well as women having very good or good social and welfare conditions showed a significantly higher level of knowledge about osteoporosis prevention. Even women undergoing bone densitometry examination present insufficient knowledge about osteoporosis prevention.

  4. Spousal influence on mammography screening: a life course perspective.

    Recently, researchers have challenged the basic tenet that marriage is universally protective for all individuals. We scrutinize socio-economic differences between married couples to shed light on the mechanisms underlying the effects of marriage. We introduce the life course perspective to investigate if differences in positive health behavior between couples are related to their early life conditions. Within the theoretical framework of cultural health capital, we hypothesize that the accumulation of cultural health capital proceeds at the marriage level when partners provide each other with health-related information and norms. For this purpose, we examine the influence of the childhood preventive health care behavior of both wives and husbands on the initiation of mammography screening for a sample of Belgian women (N = 734). Retrospective life histories of both partners are provided by the Survey of Health, Ageing and Retirement (SHARE) and are examined by means of event history analysis. The results show that a partner's cultural health capital affects the initiation of mammography screening by a woman in later life, even after her own cultural health capital and traditional measures of socio-economic status (SES) are taken into account. In line with cumulative advantage theory, it seems that inequalities in cultural health capital are accumulated at the marriage level. In order to shed further light on the spousal influence on health behavior, researchers should revert to early life in order to discern the attribution of premarital and marital conditions.

    Career selection is a crucial and a complex process which is also true for the medical profession. In the context of our country, due to the limited opportunity and proper guidance, migration of medical graduates to foreign countries is increasing. Though, clinical subjects have a huge attraction, basic science field has failed to impress our medical graduates. In current scenario, basic science field seems to be a dumping site for the incompetent as the candidates who have failed trying their luck elsewhere stumble upon basic science careers though it is not true for all. Moreover, a very few medical graduates are interested in developing their career as a basic scientist. Therefore, to motivate today's young medical graduates, there is a need of a good mentor along with a proper career guidance which can help them to understand the basic science field as an alternative career.

    Although the term 'genetic screening' has been used for decades, this paper discusses how, in its most precise meaning, genetic screening has not yet been widely introduced. 'Prenatal screening' is often confused with 'genetic screening'. As we show, these terms have different meanings, and we...... examine definitions of the relevant concepts in order to illustrate this point. The concepts are i) prenatal, ii) genetic screening, iii) screening, scanning and testing, iv) maternal and foetal tests, v) test techniques and vi) genetic conditions. So far, prenatal screening has little connection...... with precisely defined genetics. There are benefits but also disadvantages in overstating current links between them in the term genetic screening. Policy making and professional and public understandings about screening could be clarified if the distinct meanings of prenatal screening and genetic screening were...

    2001-08-01

    The relation of personal characteristics, health and lifestyle behaviors, and cancer screening practices to current colorectal cancer (CRC) screening was assessed and compared with those factors' relation to current mammography screening in women and prostate-specific antigen (PSA) screening in men. A cross-sectional random-digit-dialed telephone survey of 954 Massachusetts residents aged 50 and older was conducted. The overall prevalence of current CRC screening was 55.3%. Logistic regression results indicated that family history of CRC (odds ratio [OR] = 1.98; 95% confidence interval [CI] = 1.02, 3.86), receiving a regular medical checkup (OR = 3.07; 95% CI = 2.00, 4.71), current screening by mammography in women and PSA in men (OR = 4.40; 95% CI = 2.94, 6.58), and vitamin supplement use (OR = 1.87; 95% CI = 1.27, 2.77) were significant predictors of CRC screening. Health and lifestyle behaviors were related to increased current CRC, mammography, and PSA screening. Personal factors independently related to CRC screening were not consistent with those related to mammography and PSA screening. This lack of consistency may reflect different stages of adoption of each type of screening by clinicians and the public.

    Full Text Available Well-developed point-of-care (POC cancer screening tools have the potential to provide better cancer care to patients in both developed and developing countries. However, new medical technology will not be adopted by medical providers unless it addresses a population's existing needs and end-users' preferences. The goals of our study were to assess primary care providers' level of awareness, interest, and preferences in using POC cancer screening technology in their practice and to provide guidelines to biomedical engineers for future POC technology development. A total of 350 primary care providers completed a one-time self-administered online survey, which took approximately 10 minutes to complete. A $50 Amazon gift card was given as an honorarium for the first 100 respondents to encourage participation. The description of POC cancer screening technology was provided in the beginning of the survey to ensure all participants had a basic understanding of what constitutes POC technology. More than half of the participants (57% stated that they heard of the term "POC technology" for the first time when they took the survey. However, almost all of the participants (97% stated they were either "very interested" (68% or "somewhat interested" (29% in using POC cancer screening technology in their practice. Demographic characteristics such as the length of being in the practice of medicine, the percentage of patients on Medicaid, and the average number of patients per day were not shown to be associated with the level of interest in using POC. These data show that there is a great interest in POC cancer screening technology utilization among this population of primary care providers and vast room for future investigations to further understand the interest and preferences in using POC cancer technology in practice.

    2002-07-01

    Developing effective programs to promote colorectal cancer (CRC) screening requires understanding of the effect of healthcare system factors on access to screening and adherence to guidelines. This study assessed the role of insurance status, type of plan, the frequency of preventive health visits, and provider recommendation on utilization of CRC screening tests using a cross-sectional, random-digit-dial survey of 1002 Massachusetts residents aged > or =50. A broad definition of CRC screening status included colonoscopy or barium enema (screening or diagnostic) within 10 years, flexible sigmoidoscopy (FSIG) within 5 years, and fecal occult blood testing (FOBT) in the past year as options; 51.7% of subjects aged 50 to 64 and 61.5% of older subjects were current. The uninsured had the lowest current testing rate. Among insured participants, type of insurance had little impact on CRC testing; older subjects enrolled in HMOs had marginally higher rates, although not statistically significant. Increased frequency of preventive health visits and ever receiving a physician's recommendation for FSIG or ever receiving FOBT cards were associated with higher rates of CRC screening among both age groups. Even when broad criteria are used to define current CRC screening status, a substantial proportion of the age-eligible population remains underscreened. Obtaining regular preventive care and receiving a physician's recommendation for screening appear to be potent facilitators of screening that should be considered in designing promotional efforts.

    Optimal tuberculosis testing usually involves sputum centrifugation followed by broth culture. However, centrifuges are biohazardous and scarce in the resource-limited settings where most tuberculosis occurs. To optimize tuberculosis testing for these settings, centrifugation of 111 decontaminated sputum samples was compared with syringe-aspiration through polycarbonate membrane-filters that were then cultured in broth. To reduce the workload of repeated microscopic screening of broth cultures for tuberculosis growth, the colorimetric redox indicator 2,3-diphenyl-5-(2-thienyl) tetrazolium chloride was added to the broth, which enabled naked-eye detection of culture positivity. This combination of filtration and colorimetric growth-detection gave similar results to sputum centrifugation followed by culture microscopy regarding mean colony counts (43 versus 48; P = 0.6), contamination rates (0.9% versus 1.8%; P = 0.3), and sensitivity (94% versus 95%; P = 0.7), suggesting equivalency of the two methods. By obviating centrifugation and repeated microscopic screening of cultures, this approach may constitute a more appropriate technology for rapid and sensitive tuberculosis diagnosis in basic laboratories.

    Most midwives and nurses do not write for publication. Previous authors on this topic have focussed on the processes of writing and getting published. Although definitive English usage style guides exist, they are infrequently consulted by new midwifery authors. To enable new writers to confidently apply the basic skills of scientific writing when preparing a paper for publication. The basic skills needed for scientific writing are the focus of this paper. The importance of careful word choices is discussed first. Next, the skills of writing sentences are presented. Finally, the skills of writing paragraphs are discussed. Examples of poor and better writing are given in relation to each of these basic elements.

  2. The basic aerodynamics of floatation

    1983-09-01

    The original derivation of the basic theory governing the aerodynamics of both hovercraft and modern floatation ovens, requires the validity of some extremely crude assumptions. However, the basic theory is surprisingly accurate. It is shown that this accuracy occurs because the final expression of the basic theory can be derived by approximating the full Navier-Stokes equations in a manner that clearly shows the limitations of the theory. These limitations are used in discussing the relatively small discrepancies between the theory and experiment, which may not be significant for practical purposes.

  8. Are immigrants and nationals born to immigrants at higher risk for delayed or no lifetime breast and cervical cancer screening? The results from a population-based survey in Paris metropolitan area in 2010.

    Directory of Open Access Journals (Sweden)

    Claire Rondet

    Full Text Available OBJECTIVES: This study aims to compare breast cancer screening (BCS and cervical cancer screening (CCS practices of French women born to French parents with those of immigrants and nationals born to immigrants, taking their socioeconomic status into account. METHODS: The study is based on data collected in 2010 in the Paris metropolitan area among a representative sample of 3000 French-speaking adults. For women with no history of breast or cervical cancer, multivariate logistic regressions and structural equation models were used to investigate the factors associated with never having undergone BCS or CCS. RESULTS: We confirmed the existence of a strong gradient, with respect to migration origin, for delaying or never having undergone BCS or CCS. Thus, being a foreign immigrant or being French of immigrant parentage were risk factors for delayed and no lifetime screening. Interestingly, we found that this gradient persisted (at least partially after adjusting for the women's socioeconomic characteristics. Only the level of income seemed to play a mediating role, but only partially. We observed differences between BCS and CCS which suggest that organized CCS could be effective in reducing socioeconomic and/or ethnic inequities. CONCLUSION: Socioeconomic status partially explained the screening nonparticipation on the part of French women of immigrant origin and foreign immigrants. This was more so the case with CCS than with BCS, which suggests that organized prevention programs might reduce social inequalities.

    2016-01-01

    Based on the latest version of designing codes both for buildings and bridges (GB50010-2010 and JTG D62-2004), this book starts from steel and concrete materials, whose properties are very important to the mechanical behavior of concrete structural members. Step by step, analysis of reinforced and prestressed concrete members under basic loading types (tension, compression, flexure, shearing and torsion) and environmental actions are introduced. The characteristic of the book that distinguishes it from other textbooks on concrete structures is that more emphasis has been laid on the basic theories of reinforced concrete and the application of the basic theories in design of new structures and analysis of existing structures. Examples and problems in each chapter are carefully designed to cover every important knowledge point. As a basic course for undergraduates majoring in civil engineering, this course is different from either the previously learnt mechanics courses or the design courses to be learnt. Compa...

    Cervical cancer and its precancerous lesions caused by human papilloma virus (HPV) are steadily increasing in women in Japan. In comparison with women in other resource-rich countries, young women in Japan have a dismally low screening rate for cervical cancer. Our preliminary research has shown that 20-year-old women in Japan usually ask their mothers for advice regarding their initial cervical cancer screening. The objective of our current research is to determine the social factors among mothers in Japan that are causing them to give advice to their daughters regarding the HPV vaccine and cervical cancer screening. The survey's targets were mothers who had 20-year-old daughters. We recruited respondents from the roster of a commercial internet survey panel. We analyzed for correlations between a mother's knowledge concerning cervical cancer, her recent cancer screening history, and the advice she gave to her daughter regarding cervical cancer screening. We obtained 618 valid answers to the survey. Compared with mothers who did not get screening, mothers who had cervical cancer screening had significantly more knowledge about cervical cancer and its screening (p < 0.05). The daughters of mothers with recent screening had received HPV vaccination more often than those of mothers without recent screening (p = 0.018). Mothers with recent screening histories tended more often to encourage their daughters to have cervical cancer screening (p < 0.05). When mothers were properly educated concerning cervical cancer and its screening, they were significantly more likely than before to recommend that their daughters have it (p < 0.0001). In young Japanese women, given the important role their mothers have in their lives, it is probable that we could improve their cervical cancer screening rate significantly by giving their mothers better medical information, and a chance to experience cervical cancer screening for themselves.

    2008-03-01

    Maize (Zea mays) is an excellent model for basic research. Genetic screens have informed our understanding of developmental processes, meiosis, epigenetics and biochemical pathways--not only in maize but also in other cereal crops. We discuss the forward and reverse genetic screens that are possible in this organism, and emphasize the available tools. Screens exploit the well-studied behaviour of transposon systems, and the distinctive chromosomes allow an integration of cytogenetics into mutagenesis screens and analyses. The imminent completion of the maize genome sequence provides the essential resource to move seamlessly from gene to phenotype and back.

    The special mechanical properties of nanoparticles allow for novel applications in many fields, e.g., surface engineering, tribology and nanomanufacturing/nanofabrication. In this review, the basic physics of the relevant interfacial forces to nanoparticles and the main measuring techniques are briefly introduced first. Then, the theories and important results of the mechanical properties between nanoparticles or the nanoparticles acting on a surface, e.g., hardness, elastic modulus, adhesion and friction, as well as movement laws are surveyed. Afterwards, several of the main applications of nanoparticles as a result of their special mechanical properties, including lubricant additives, nanoparticles in nanomanufacturing and nanoparticle reinforced composite coating, are introduced. A brief summary and the future outlook are also given in the final part.

    This paper is a short survey on four basic questions on Artin-Tits groups: the torsion, the center, the word problem, and the cohomology ($K(\\pi,1)$ problem). It is also an opportunity to prove three new results concerning these questions: (1) if all free of infinity Artin-Tits groups are torsion free, then all Artin-Tits groups will be torsion free; (2) If all free of infinity irreducible non-spherical type Artin-Tits groups have a trivial center then all irreducible non-spherical type Artin-Tits groups will have a trivial center; (3) if all free of infinity Artin-Tits groups have solutions to the word problem, then all Artin-Tits groups will have solutions to the word problem. Recall that an Artin-Tits group is free of infinity if its Coxeter graph has no edge labeled by $\\infty$.

    2009-05-01

    In this review, we highlight recent applications of machine learning to virtual screening, focusing on the use of supervised techniques to train statistical learning algorithms to prioritize databases of molecules as active against a particular protein target. Both ligand-based similarity searching and structure-based docking have benefited from machine learning algorithms, including naïve Bayesian classifiers, support vector machines, neural networks, and decision trees, as well as more traditional regression techniques. Effective application of these methodologies requires an appreciation of data preparation, validation, optimization, and search methodologies, and we also survey developments in these areas.

    2013-01-01

    The Basic Operational Robotics Instructional System (BORIS) is a six-degree-of-freedom rotational robotic manipulator system simulation used for training of fundamental robotics concepts, with in-line shoulder, offset elbow, and offset wrist. BORIS is used to provide generic robotics training to aerospace professionals including flight crews, flight controllers, and robotics instructors. It uses forward kinematic and inverse kinematic algorithms to simulate joint and end-effector motion, combined with a multibody dynamics model, moving-object contact model, and X-Windows based graphical user interfaces, coordinated in the Trick Simulation modeling environment. The motivation for development of BORIS was the need for a generic system for basic robotics training. Before BORIS, introductory robotics training was done with either the SRMS (Shuttle Remote Manipulator System) or SSRMS (Space Station Remote Manipulator System) simulations. The unique construction of each of these systems required some specialized training that distracted students from the ideas and goals of the basic robotics instruction.

  7. The basic aerodynamics of floatation

    Davies, M. J.; Wood, D. H.

    1983-09-01

    It is pointed out that the basic aerodynamics of modern floatation ovens, in which the continuous, freshly painted metal strip is floated, dried, and cured, is the two-dimensional analog of that of hovercraft. The basic theory for the static lift considered in connection with the study of hovercraft has had spectacular success in describing the experimental results. This appears surprising in view of the crudity of the theory. The present investigation represents an attempt to explore the reasons for this success. An outline of the basic theory is presented and an approach is shown for deriving the resulting expressions for the lift from the full Navier-Stokes equations in a manner that clearly indicates the limitations on the validity of the expressions. Attention is given to the generally good agreement between the theory and the axisymmetric (about the centerline) results reported by Jaumotte and Kiedrzynski (1965).

    2016-12-01

    The objective of this paper is to identify factors associated with compensation for Emergency Medical Technician (EMT)-Basics and Paramedics and assess whether these associations have changed over the period 1999-2008. Data obtained from the Longitudinal EMT Attributes and Demographic Study (LEADS) surveys, a mail survey of a random, stratified sample of nationally certified EMT-Basics and Paramedics, were analyzed. For the 1999-2003 period, analyses included all respondents providing Emergency Medical Services (EMS). With the addition of a survey in 2004 about volunteers, it was possible to exclude volunteers from these analyses. Over 60% of EMT-Basics reported being either compensated or noncompensated volunteers in the 2004-2008 period. This was substantially and significantly greater than the proportion of EMT-Paramedic volunteers (EMT-Paramedics earned significantly more than EMT-Basics, with differentials of $11,000-$18,000 over the course of the study. The major source of earnings disparity was type of organization: respondents employed by fire-based EMS agencies reported significantly higher earnings than other respondents, at both the EMT-Basic and EMT-Paramedic levels. Males also earned significantly more than females, with annual earnings differentials ranging from $7,000 to $15,000. There are a number of factors associated with compensation disparities within the EMS profession. These include type of service (ie, fire-based vs. other types of agencies) and gender. The reasons for these disparities warrant further investigation. Studnek JR . Compensation of Emergency Medical Technician (EMT)-Basics and Paramedics.
